John Stuart Mill and Utilitarianism Essay

John Stuart Mill published Utilitarianism in 1861 in installments in Fraser’s Magezine it was later brought out in book form in 1863. The book offers a candidate for a first principle of morality, a principle that provides us with a criterion distinquishing right and wrong. The unilitarian candidate is the principle of utility, which holds that â€Å"actions are right in proportion as they tend to promote happiness; wrong as they tend to produce the reverse of happpiness. By happiness is intended pleasure and the absence of pain; by unhappiness, pain and the privation of pleasure.† One version of cecular utilitarianism was represented by William Godwin the husband of Mary Wollstonecraft and father of Mary Shelley, who achieved great notoriety with the publication of hil Political Justice of 1793. Godwin’s use of the principle of utility for the cause of radical political and social critique began the identification of utilitarianism with anti-religiosity and with dangerous democratic values. The second version of secular utilitarianism, and the one that inspired Mill, arose from the work of Jeremy Bentham. Benthan, who was much more successful than Godwin at building a movement around his ideas, employed the principle of utility as a device of political, social, and legal criticism. Bentham’s interest in the principle of utility did not arise from concern about ethical theory as much as from concern about lefislative and legal reform. Though Bentham and Godwin intended it to have this function in the late eighteenth century, utilitarianism became influential only when tied with the political machinery of the Radical party, which had particular prominence on the English scene in the 1830’s.

Mr Daniel

Contract is a part of the business transaction. Contract is an agreement between two or more parties each of whom has the intention to create a legal relation to have a lawful object between them. Contract is more used in the partnership business where each party has a common goal, trust one another and a specific time period. IQ . 1 : What are the essential elements of forming a valid contract? Explain the importance of each element by providing relevant legal principles derived from decided cases: An agreement that can be enforced by law is considered as a contract Cones v.Daniel 1894). An agreement is enforceable by law when it fills up certain conditions that are regarded as essential element of valid contract. Essential elements are: Offer and Acceptance, Lawful Consideration, Intention to create Legal Relationship, Certainty: Offer Offer is crucial element for a contract, is very important that the offer to intend to for a term as an expression of willingness to enter in to a c ontract, contract which will became lawful upon acceptance. Gibson V Manchester City Council (1979)1 WALL 294 HAL) Acceptance An acceptance is a willingness that the offered agree to all the terms of the offer has made. Also the acceptance must be ‘mirror image' of the offer. (Day Morris Associates v Voice 2003 COCA civic 189). If the offered try to set up new terms on the offer, this normally is a counter offer which will kill the original offer. (Hyde v Wrench 1840). Lawful Consideration: Consideration is defined as an acts or a promise of a payment or charge or value which is called ‘Consideration' made from promise to the promise or both. Currie v Miser 1875) An agreement should be based on the freedom of contact theory of all parties. Free consent is hampered when coercion, mistake, fraud and misrepresentation are made. Chapel & Co. V Nestle 1960 AC). Intention to create Legal Relationship: A legal relation is created through the agreement that is intended. An agree ment to sell or buy a product is agreement intended to make legal relationship and is therefore contract. A contact may not be valid if the participants they are not intending to create legal relation. (Buffalo v Buffalo 1919).Domestic and Social contracts are not considered to be a legal relation. Cones v Badminton 1966). Also commercial agreements is normally considered that is made in a business context and automatically is an intention to create legal relation. Case: Sees petroleum v Commissioner of customs and Excise 1976). Family agreements can be enforceable if there is a clearly made in to a ‘business connect'(Smelling v John G Smelling Ltd 1973). Certainty As a contract to be valid it must contain terms of the contract and if a important term is hidden that contract will not be lawful.IQ . 2: Describe different types of contract usually undergone in business context. Critically analyze the legal impact of distance selling contract.

Distance selling contract regulations: sellers give certain basic information to customer, deliver goods within 30 days, and provide customers a right to cancel their order. All business must comply with the ‘Sale of Goods Act' IQ . 3: Analyze the contrasting aspects of different kind of terms generally used in a commercial contract. 200 words The lawfulness of commercial contract based on different kind of terms.These terms are considered as implied and express terms. Four categories of implied terms (Porter v Atonement U. D. CHIC 5) are: Terms Implied by fact: Under this term court believe that both parties of the contract know about the fact. Terms implied in law: Under this term court indicate a specific law of defined type in the contract. That law protects the weaker party in the contract. Terms implied by custom: In this term, local custom is applied on the contract. Terms implied by trade usage: Terms regularly used in contracts within a particular business can be implied on other such contract.Express terms are: a) Oral contract b) Written contract c) Parole evidence role d) Collateral contract There are three types of contractual terms: a) Condition: Major term of contract. Serious consequence occurs when it is broken. (Passwords v Speers and pond 1876) b) Warranties: Under this term an affected party an sue for damage when it is breached but cannot terminate the contract. C) In nominate term: If this type of term is breached serious or negl igible result can occur depending on the particular fact. ‘Implied terms are more sensitive to deal with than express terms in a business contract' – how far would you agree with this comment?In contract implied terms refers to terms that are not directly written in the contract but are introduced into contract by the court or by statute. Express terms are conditions that are directly written and agreed by both parties at the time of contract made. As the terms are not mentioned in the contract, it is more sensible to deal with during conflict than express terms. Task 2: Application of Contracts in Business Situations Q. 1: (a) Green Pharmacy put an advertisement in a trade Journal stating: for the wholesale buyers only, our ‘new moisturizing creams' are now at a special low price of Ole per dozen. Mr. Khan, one of Green Pharmacy trusted vendors, rushed to one of your show room and wanted to place a large order. Meanwhile the company made a new decision not to sel l the creams any more. Mr. Khan became cross and he wished to pursue a legal action against the company. Advice Green Pharmacy about the possible legal consequence. Justify your comments with reference to similar case precedents. In the given business scenario Green put an advertisement to sell its new moisturizing cream at a special low price Green Pharmacy was making only an invitation to treat. (Partridge v Christened (1968) 1 WALL 1204). As a result Mr.. Khan one of the trusted vendors rushed to one of the show room and wanted to place a large order but he was refused to give order. As a result he wished to pursue a legal action against the company. Mr.. Khan wanted to make an offer to Green Pharmacy to ay the goods but was no acceptance from the company therefore was not valid contract, in event of seeking legal action from Mr. Khan will not affect Green Pharmacy in any way legally. (b) You work into the night to complete ‘an important report' for your immediate boss, Tan ia.Tania is very pleased with the report and says ‘l know you have worked very hard on this, I will make sure there's an extra IEEE in your pay at the end of the month. Can you enforce this promise? 100 words In the given situation you can't make lawsuit against Tania although it is a oral promise that is done with spoken words. Tania makes a statement or promise which we can call consideration but that consideration was completed before Tania has made her promise. We called this situation past consideration so it can be a lawful consideration (Re Macrame 1951). (c) Joe works in the purchase department of Green Pharmacy. He lives near to you.By an agreement he provides you with a lift to work in return for a contribution towards the petrol. Would this contract be legally enforceable? Justify your answer with legal arguments. 75 words In the above situation Joe can't be enforced in this contract legally due to lack of intention to create legal relation, furthermore the agreemen t was done in a social context, if in event to seek legal action the court will not enforce this agreement (Buffalo b Buffalo 1919) Q. 2: Albany is the business development manager of Green Pharmacy. Four months ago he bought a ‘Landmasses' car from Brand's Garage Ltd for use in his business activities.He paid El 2,500 for the car and was given a written guarantee in the following terms. ‘Brand's Garage Ltd guarantees that, for three months from the date of purchase, it will put right free of charge any defects in the vehicle which cannot be discovered on roper examination at the time of purchase. Thereafter all work and materials will be charged to the customer. ‘ The sales manager recommended to Albany that he should take out the ‘special extended warranty under which, for payment of ?350, the car would have been guaranteed in respect of all defects for a further two years, but Albany declined.Last week the engine and gearbox seized up. The repairs will cos t E,OHO. Advise Albany. Would your answer differ if he bought the car only for his personal use? Is made with personally or commercially. All contracts are made up with the essential elements. When Albany purchases a Landmasses car from Brand's Garage Ltd for use in business activities, he made a legal contract through offer and acceptance, and a written agreement. It also includes the consideration in the contract that defines each party to the agreement gets something.There was the existence of the certainty element of the contract through which Brenda indicates for three month from the date of purchase they will provide warranty service of the car. If Albany purchase the car for personal use he would make a contract with the seller of the by maintaining the element of the valid contract. Albany can not make a claim for compensation of the car if want it to do that because was outside of the warranty was given. Although if Albany would buy the car for personal use he has the right to lawsuit against the Brenda' to recover the cost repair due to Sale Goods Act implied terms of satisfactory quality.Q. 3: Explain the effects of the following in the running of a Pharmaceutical company such as Green Pharmacy: a) Breach of conditions, and, nominate terms Breach of condition: Condition is the basic term of contract we also can call it hart of the contract. When condition is breached, the affected party can sue as well as end he contract and claim for damages. Warranty: Warranties as a secondary condition can be a specific kind of terms representation of fact that the law can enforce against the warrants.If a warranty is breached the victim party can only demand for compensation but cannot end the contract, therefore Green Pharmacy offer replacements which will conduct to damages only. Nominate terms: As a result of such breach the innocent party is deprived of the whole benefit of the contract. The inexperience vendors will be entitled to repudiate the contract and to get compensations (Hong Kong fir shipping co. Ad v Sukiyaki Essen Aisha Ltd (1962) b) Legality of exemption clauses. Please include relevant examples to explain different aspects of the terms. 00 words An exemption clause is a term in the contract made by one party to protect them from lawsuit done by other party for damage,loss,negligence or non-performance etc. It is done usually by the party who draft the agreement. For example, a digital camera shop use exemption clause in their selling document where they accept no liability for any damaged camera after selling it to customer. Outsource generally describes exemption clauses narrowly to e if it is logical in specific perspective.An exemption clause can be included and bound into a contract if it is written in a signed contractual document; it does not fact whether the party understands it. Task 3: Principles of Liability in Business Negligence Q. 1: In what aspects, liabilities in tort are different from contractual liabilit ies? Give examples of ‘duty of care' in the context of someday- to- day situations. Explain the concept of ‘causation' and ‘remoteness' in the tort of negligence. 220 words Tortuous Contractual liability holds more privacy than liabilities in tort (Fleming, 1984).Sole proprietorship and Partner in partnership are responsible for the tort committed by them and torts committed by the business. In the contractual liability parties are engaged with one another by mutual consent which is conducted by the contract. On the other hand, the relationship in the tortuous liability is imposed by the law, the defendant must responsible the claimant a duty of care. The basic contrast between the contractual liability and the liability in tort is that the first is the result of agreement whereas the second is the result of law.Day to day examples of duty of care: ) Keepers of dangerous pets will hold a duty of care to people who will be likely to be affected. B) Lorry drivers owe s a duty of care to his goods that it's delivering. According to the law, duty of care is a legal responsibility that is applied on an individual requiring maintains a reasonable care during completing a specific task to overtake any acts that make Jeopardize others. Duty of care is done by a employer to his employees, by a traffic police to the pedestrian, by a supplier to the manufacturer for the quality of the raw materials etc.Causation defines and determines the extension of liability. Causation is the indicator through which one party proves that another party makes loss to them that is considered before damages. It may be difficult to prove when there is more than one cause. Remoteness determines how much a defendant is responsible for his wrongful doings. A defendant must make up the damages or loss if it is within the reasonable consideration. Q. 2: Explain the nature of liability in negligence by giving reference to different scenarios. Negligence is not intentional tort b ut accidental.Negligence liability holds that defendant know about the probable risk that can occur damage largely to the injured party. Here the injured party does not know about the risk before it happens. Negligence liability also assumes that the defendant has control power over the probable risk of harms that caused the plaintiff injury. (Lewis, R. , Morris, A. And Elephant, K. 2006). For example, negligence liability occurs when a landlord sell a portion of his property to a customer although knowing about the legality problem in the property documents that may cause serious damage in future if any legal issues increases.In this situation the buyer of the property will know about the problem and damages after the occurrence happens. Another example, negligence liability occurs when a nurse does not mention the medicine to the patient who has no knowledge about the medicine causing the patient take wrong medicine. Q. 3: Explain the legal requirements to hold employers vicarious ly liable for the torts committed by their employees. Vicarious liability in English law is a doctrine that applies rigorous liability on the employers for the wrongdoing of their employees (CRY-Evans Canada Ltd. . Pettifoggers). In this perspective, the person who is vicariously liable is free from blame although the person is legally responsible. An employer is vicariously responsible for doing the conduct of employees or a group of employees, agents, supervisors or managers, a person deployed by the firm disturbing a member, legislation that applies if the person was an employee and not from a contractor or agency. (Merges Docks & Harbor Board v Cogging and Griffith Ltd 1947). We can consider tort of an employee if occurs to connection with the person's employment.Without taking all responsibilities the employers may be held liable for the actions of the employees. (Limps v London General Omnibus Co 1862) Also we may have another situation where the driver of a bus company is not in his course of employment where is injures passengers it can not be responsible for the accident. (Beard v London General Omnibus Co 1900) Courts attribute to the employer where the employers' objectives do not reach in the absence of the employee's serious risk which has committed.So, there are some close connection between the tortuous act of the employee and the circumstances of his employment to establish a vicarious liability. Examples of vicarious liability are: employees seize the goods of the firm. Task 4: Application of Principles of Liability in Business Situations Q. : By applying the relevant legal principles answer the following: (a) what is the level of duty of care to be shown by (1) a learner driver (2) a Chinese herbal doctor working in England and (3) Junior doctor in a hospital? The duty of care refers to the principle that the duty to take responsible care to avoid foreseeable injury to a neighbor.A learner driver Must know the rules and regulations of the tra ffic and level of care is not been different from all other drivers. (Nettlesome v Weston 1971). Understand the possible magnitude of the probable harm or injury occurred on roads. Know the importance f the social value of this activity. Chinese herbal doctor A doctor must mention reasonable harm and can not be considered a full doctor therefore is not grade of comparison. (Sharon v Situ 2004). The relationship between the defendant and the claimant about proximate cause.A Junior doctor To practice under the supervision of senior doctor (Bola v Iffier Hospital Management Committee 1957). Maintain reasonable standard of the profession. Avoid negligence actions for medical malpractices. Know the bad effect of malpractice that causes harm or injury. (b) Green Pharmacy engages Mr. Ken, a local electrician, to rewire its office. Two weeks later Leo, a visitor, is electrocuted. Discuss Green Pharmacy liability in tort. Would your answer differ if Green Pharmacy put the following notice at the entrance: ‘Persons entering these premises do so at their own risk? 25 words A tort liability is the legal obligation of a party which causes to suffer or loss someone as a result of a civil wrong or injury. Green Pharmacy has experience in defending clients, variety of personal injury. In this scenario it is found that one of the visitors has attacked by the electrocuted. There was a rule to set up a notice for awareness. But due to negligence of the employee he notice was not hung. As a result, the Green Pharmacy is responsible for the accident of the visitors. The visitors can sue for getting the compensation of the damage.If there was the rule in the entrance: ‘Persons entering these premises do so at their own risk. In this perspective the visitor should follow the notice in the entrance. If not follow Green Pharmacy will not responsible for the accident. The visitor cannot sue against the company for getting the compensation for the damage. Q. 2: collect his o wn television from a repair shop. He parks his van carelessly and it moves off, injuring Kelly, a pedestrian. Is Green Pharmacy vicariously liable? Vicarious liability indicates a situation where someone is liable for the acts of another person.In this business scenario John is van driver employed by Green Pharmacy who use the van for his personal use to carry a television from a repair shop. As he parks the van carelessly that resulting injured Kelly a pedestrian, the pedestrian can sue against the Green Pharmacy because the owner of the van is the Green Pharmacy who not is vicariously liable for the injury of the pedestrian. Beard v London General Omnibus Co 1900 (b) Robert, who is a security guard in Green Pharmacy head office, has been encouraged by the company to keep order by force – if necessary. One night he grabbed one Martins on suspicion and stabbed him in the back.Discuss the potential vicarious liability of Green Pharmacy. 100 words Here Green Pharmacy plays the role of the employer and Robert is the employee of this. Green Pharmacy is vicariously liable for the act of the Robert because he has done the action encouraged by the company to protect his Job. Seemingly, Green Pharmacy is free from the blame but it is legally liable for the negligence of the employee. As a result Mr.. Mantis affected by stabbing can demand for the compensation that must be paid y the company. Many employers are not aware that they can be liable for a range of actions done by their employee in the course of their employment.Conclusion: To regulate and expand the business the importance of law is increasing day by day. The capacities and culture of the different organization and nations are not same. Law provides the fundamental understanding of the negotiation deals that is required in the business. Legitimate contract helps to debate settlement of the business organization in the court by legal Jurisdictions. Top management of a organization should know the reas onable information about the various elements of he agreement to understand and get important point in the business arena.

Integrity in the System of Corporate Accountability The corporate accounting system encompasses the traditional accounting and also the social reporting method. The social re porting concepts are supposed to revolve around environmental and also the social aspects of the assets and liabilities reporting methods. It is concerned with the benefits and cost associated with the issues and the verification, assurance provided by the auditors (Rao, Tilt and Lester, 2012). It encompasses various issues which revolve around the interactions and the inclusion of elements like ethics, corporate governance, social and environmental accounting, philanthropy activities (Pollock, 2011). The development of social corporate accounting encompasses the formulation of accounting systems as per the guidelines provided by the Global Reporting Initiative (GRI) to provide accuracy in the global and environmental accounting. Role of Auditors The role of internal auditors of the company identifies the errors and checks whether the measures undertaken by the management are in compliance with the norms and regulations. The duty of internal auditor is to check of the transparency o f accounting system and also provide advice based on the conducted auditing function (National Fraud Authority, n.d). One of the prime objectives of the auditor is to provide the stakeholders and shareholders the key assurance that risk management activities are carried out effectively. The auditor’s incompetence will be observed when he/she would be able to uncover the misappropriations in the accounting systems and also the preparation of the timely accounting reports, risk management system and various other activities.

The Curriculum Descriptive Theory Essay Example | Topics and Well Written Essays - 1000 words

The Curriculum Descriptive Theory - Essay Example (Marsh 2004, p. 201) The analysis in this paper is focused on the curriculum descriptive theory. The descriptive theory is marked against other theories in several ways. But its main distinction resides on its principle which is to understand the various steps and procedures in curriculum development and the relationships among them. This is achieved by identifying how curriculum development actually takes place, especially in school settings. (Marsh, p. 201) There are scholars who label the descriptive theory as the scientific theory as well. The reason behind is, the methods employed in theorizing the curriculum is clinical and follows the scientific approach. Alfie Kohn (2000), who stressed that descriptive theory is technically aligned with constructivism, cites four of its principles that facilitate learning. According to him, the teacher should It is far more difficult to figure out how to implement descriptive theory than it is to generate it. I am reasonably intelligent, and it took me 14 years of almost full-time effort to figure out how to consistently work just four thinking skills into a detailed and effective curriculum. (Reigeluth 1999, p. 15) Indeed, some degree of support was given by Dwayne Huebner (1999, p. 215) asserting that curricularists must be concerned not only with the descriptive theory but also with prescriptive theory. This statement explained the descriptive theory best and its relationship with the prescriptive theory content-wise in the perspective of most of its critics. That is, he who would talk about curriculum must do more than describe what’s going on; many people want him to issue imperatives about what should be done. We should not forget that it is the scholars themselves who widely believe that theories are generally descriptive in nature. This is because situations like curriculum development can be thought of as dealing with cause-and-effect relationships or with flows of events in

Gun Control in the United States Research Paper

Gun Control in the United States - Research Paper Example In short, more thorough background checks of those people who wish to buy guns is a necessity for stricter gun control due to the increased level of crimes involving guns in our communities. However, as DeConde (2001) notes, ‘no social issue of recent decades has produced more distorted data and contention among Americans than the struggle to control gun violence’ (p. 3), and so the issue is far from simple. There are well over 200 million guns in the United States (far more than in other developed countries) while the gun laws are comparatively weak. Canter ( 2006) found that when the US is compared to other economically-developed and democratically-governed countries, the age-adjusted rate of death by firearms is eight times as high as the average of the other countries pooled together. It is obvious that current background checks are not good enough. The massacre at Virginia Tech in April 2007, which left 32 staff and students dead, was carried out using two weapons, both of which was purchased completely legally at local stores. The killer had, two years earlier, been declared mentally ill and a danger to himself by a judge. This alone should surely have disqualified him from purchasing firearms, but he was never placed on a list banning him from buying guns in Virginia. The issue here was surely the vastly-different state laws on gun controls. What is needed is strong national laws, and checks conducted using nationwide databases. Fig. 1. The Geography of Gun Deaths in America. Source: atangledweb.org [Accessed January 27 2011] Background checks as a feature of the gun control debates in the United States date all the way back to the 1930s, when the District of Columbia introduced a 48-hour cooling off period for the purchase of firearms. Indeed, until the 1970s, the National Rifle Assocation (NRA) – the leading group in the pro-gun lobby, actually supported such policies. From 1986, there was a nationwide campaign for the introduction of a waiting period on all gun purchases, and in 1993, the passage of the Brady Handgun Violence Prevention Act established a 5-day waiting period, during which time background checks were to be conducted to ascertain whether a gun could responsibly be sold to the applicant. Spitzer (2002) produced a list of the reasons for which a gun purchase could be blocked: if the applicant had been convicted of a crime carrying a sentence of more than a year, if a restraining order had been placed against them for violence, if they had been convicted of domestic abuse, if they had been arrested for using or selling banned substances, if they were deemed to be mentally unstable, or if they were an illegal alien (p. 51).The Brady Act is held to have had some effect on firearm-related violence. Canter (2006) noted that the number of deaths by guns fell from 37,776 in 1992 to 32,436 in 1997 (p. 3). Nevertheless, this can scarcely be hailed as the major breakthrough in tackling gun crime which is n eeded in the United States. While the Supreme Court struck down the requirement for police to conduct background checks in 1997, handgun background checks have largely continued. In theory, all this should have done much to ensure that only those who could safely be sold a handgun would be able to procure one. However, there have been major issues. In 1998, the Federal Bureau of Investigation (FBI) set up its National Instant Criminal Background

Critically evaluate the religious conflict in Northern Ireland using Essay

Critically evaluate the religious conflict in Northern Ireland using both contemporary and traditional sociological theories. Examine the ways in which the con - Essay Example The popular perception usually centres on such things as gang warfare, tribal disputes, or religious animosity or perhaps even an inclination for straight-forward mindless violence. As is so often the case, this turns out to be, if not completely misguided, at least a gross over-simplification of a complex human phenomenon. One of the main aims of this essay will be to illustrate not just how popular myths as to the causes of the Troubles in Northern Ireland are misconceived, but also how some of the more serious attempts to understand the conflict have suffered from a limited appreciation of the multiple factors involved. In order to pursue this goal, it is first necessary to identify the main historical precursors that led to the conflict and the various strategies that were engaged by way of resolution. We will then be in a better position to assess the different theoretical frameworks that have suggested a way forward and to ascertain how they might be applied to the political reality of Northern Ireland from the perspective of religion and secularisation. Even before England became a Protestant country, its brand of Catholicism was different to that of Ireland. Irish Catholicism was deemed to be idiosyncratic because it followed the northern Celtic tradition. So, though both countries were Catholic, differences had already begun to emerge in their respective religious identities. Henry II of England was the first to invade Ireland gaining control over the region around Dublin but the expansion of English influence did not occur until the 16th century with the reign of Elizabeth I. It was during this period that the Ulster clans allied themselves against the invading army. By the time of Elizabeth, however, England had already left the Roman Catholic Church. The break from Catholicism was essentially political and not doctrinal, the Anglican and Catholic services remaining almost identical. It was only after Henry VIII's death and the accession of Edward VI did the tendency towards Lutheran Protestantism begin. It was also during Eliz abeth's time, in face of the threat from the Catholic Spanish, that English nationalism became wedded to Protestantism. Eventually, Ulster came to be dominated by the English and Irish leaders sought sanctuary in Europe. Their lands were confiscated and given to colonists from England. As English foreign policy had come into conflict with those of Catholic Europe, Ireland became a convenient 'back door' to European enemies. To counter this problem a program of colonial settlement called the Plantation was embarked upon. Although English settlers were at first encouraged, they were reluctant to take up the invitation and it was the Scots from Galloway, who were already accustomed to travelling to Ulster, who took up the challenge. With the arrival of the Scottish Presbyterians, the native Irish were banished to peripheral lands. There was no deliberate policy of populating Ireland with Scottish Presbyterians as, like the Catholics, they were regarded as dissenters by James 1 of England (Clayton 1998). The counties of Antrim and Down, where Presbyterians were most numerous, did not form part of the Plantation but were

Rating Your Dimensional Data Warehouse - Article Example While a sum total score of 0 would indicate a system completely unsupportive of a dimensional approach, a score of 20 would indicate a system that is fully supportive of a dimensional approach. The author outlays 12 of the 20 criteria in the article. Some of the criteria that pertain to the Architecture of the Data Warehouse are: Explicit Declaration, Conformed Dimensions and Facts, Dimensional Integrity, Open Aggregate Navigation, Dimensional Symmetry, Dimensional Scalability and Sparsity Tolerance, etc. Kimball explains Open Aggregate Navigation as follows: â€Å"The system uses physically stored aggregates as a way to enhance performance of common queries. These aggregates, like indexes, are chosen silently by the database if they are physically present. End users and application developers do not need to know what aggregates are available at any point in time, and applications are not required to explicitly code the name of an aggregate. All query processes accessing the data, even those from different application vendors, realize the full benefit of aggregate navigation.† (Kimball, 2000) Similarly, some of the criteria that fall under Administration category are: Graceful Modification, Dimensional Replication, Dimension Notification, Surrogate Key Administration, International Consistency, etc. Kimball explains Dimensinal Replication as follows: â€Å"The system supports the explicit replication of a conformed dimension outward from a dimension authority to all the client data marts, in such a way that we can only perform drill-across queries on data marts if they have consistent versions of the dimensions. Aggregates that are affected by changes to the content of a dimension are automatically taken offline in each client data mart until we can make them consistent with the revised dimension and the base fact table.† (Kimball, 2000) One of the impressive aspects of the article is its compact

How Hacking Can be Helpful Term Paper Example | Topics and Well Written Essays - 3000 words

How Hacking Can be Helpful - Term Paper Example In addition, ethical hackers do not delete files, disclose the information to public, or ruin the network once they manage to break into the security. Today corporations widely hire ethical hackers or white hat hackers to check if their security systems are strong enough to prevent strong malicious attacks. Hacking contests like Pwn2Own are organized to identify unknown vulnerabilities in computer networks and security system. It is interesting to note that leading social networks like Facebook and Twitter and search engines like Google and Yahoo offer millions of dollars to hackers who can successfully break into their security. Still some companies are overconfident about the security systems they maintain without knowing the modern tricks in computer hacking. Today it is not necessary for one to sit the whole day at computer to break into the security of an organization because there have been many simple techniques in use. Although the concept of ethical hacking can be helpful fo r companies to improve their security levels, today hacking techniques are widely used for supporting illegal purposes like credit card fraud and information theft. This paper will describe how hacking can be helpful for companies to improve their operational efficiency. ... tion of a secure wireless telegraphy technology by John Ambrose Fleming by sending inappropriate Morse code messages with the help of the auditorium’s projector (â€Å"A history of hacking†). In 1930s a major hacking event happened when Polish cryptologists Marian Rejewski, Henryk Zygalski, and Jerzy Rozycki hacked the Enigma machine code. In 1960s, university facilities like MIT’s artificial intelligence lab became a hot target for hackers. In 1965, William D. Mathew detected a vulnerability in a Multics CTSS running on an IBM 7094 and he found that this weakness causes to disclose the password file’s contents; and as a result of this flaw, any user logging into this system could see the system CTSS password file’s contents (Baker, â€Å"14 Years of SQL Injection..†). During this period, the term ‘hacker’ was used in a positive sense to represent a person with advanced computing skills who could alter computer programs beyond wh at they were actually designed to perform. Hacking activities became more common with the beginning of 1970s. In early 1970s, an individual named John Draper made a free long distance call by blowing a precise tone into a telephone that commands the system to clear a line (â€Å"A history of hacking†). Draper was repeatedly arrested throughout the1970s for telephone tampering. During the same period, the Yippie social movement made arrangements like Technical Assistance Program to back up phone hackers’ efforts to make free long distance calls. Later in this decade, two members from the Homebrew Computer Club of California began making devices called ‘blue boxes’, which were used to intrude into the phone system. The two members earned the handle ‘Berkeley Blue’ (Steve Jobs) and ‘Oak Toebark’ (Steve Wozniak) were the

Innovations In English Language Teaching Essay Example for Free

Innovations In English Language Teaching Essay Within the inter-related fields of linguistics, psychology and specifically language learning it has been recognized that language acquisition depends on several cognitive and environmental aspects. When giving instruction in a foreign language, it is also necessary to consider the language of origin already mastered by the learner, as well as the peculiarities of culture that may interfere with or otherwise have an impact on the manner in which a given language is learned (Collier, 1995). In Singapore, innovations in language learning based on these criteria have already been made, but implementation has posed a challenge (Tucker Corson, 1997). The true language expert has a deep understanding these barriers and must be prepared to come up with ideas that facilitate the change that drives the actual implementation of these innovative processes (Reza-Hernandez Clifford, 2003; Garcia, 1994). In Singapore, English has been acknowledged as the language of business and commerce, and therefore it has become crucial for greater strides to be made in passing on its knowledge to the citizens (Tucker Corson, 1997). Singapore’s national university has instituted such innovations as the creation of computerized databases that hold â€Å"profiles of Singapore-based English† as a method improving the research and development in the area of English language teaching in the country (1997, p. 227). This type of research appears to enable language instructors to understand the general areas of English that need more or better instruction. Other innovations directly affecting Singapore include the new dictionary of Southeast Asian English as well as numerous conferences that promote the improvement of the language. This research hopes to add further innovations, including in the area of technology, that would build on the projects already begun and further enhance the learning of the language in the country (Chapelle, 2003; Parker, 2007; Reza-Hernandez Clifford, 2003; Klein et al. 2006). Research Objectives The aim of this research is to find new approaches to teaching English that can be easily implemented in the Singaporean context. These will include new instructional methods, teaching aids, and the use of technologies as an integral aspect of imparting the language experience to those who learn. Research Question: How does collaborative learning, using the primary learners as mediators of the language, affect English language instruction in Singapore? Methods The major theme of the implementation strategies will be the establishment of a community of English language learners using a core group of English language institute students as mediators of the language. The use of technology will enhance the project but not be the main focus. In community building, emphasis will be placed on building bridges between and among students of language-learning institution and other schools or groups within the community (Hones, 2000; Parker, 2007; Klein, et al. , 2006). Technology will come into play as computers and the internet will provide the means of uniting persons separated by distance. It will also be used to engage the participation of native speakers of English from the United Kingdom, the United States, Australia, and other English speaking countries of the world. Technology will also be used as a supplement to the activities performed in the language-learning setting (Kamhi-Stein, 2000). The study will therefore take the form of an action research in which the use of existing educational software, games, and activities in English are used within an integrative context. This integrative context will involve the exposure of the language-learning institute students to activities with native speakers, which they will in turn pass on to a group of Singaporeans within a given community—perhaps children or youth group. The types of activities used will include the following †¢ internet word-searches and studies †¢ webquests (Teclahaimanot Lamb, 2004) †¢ on- and offline word-game applications such as Scrabble †¢ watching and discussing movies in English †¢ reading and discussing books in English These will be done together with volunteers from English speaking countries who will be instructed to maintain constant dialogue with the institute student about the activities for the duration of the session. Group chats as well as one-on-one conversations will be used. Later the student will be expected to impart the knowledge gained from the session to members of the community. Activities will be monitored via reports and observation in order to provide the data for the research.

Segmentation Essay Example for Free

Segmentation Essay Market segmentation is where marketers split the market into groups with similarities that would make it easy to target their product to the consumers, if they do not do this then they could waste money and time on targeting the wrong people. The company would be trying to maximise their sales so that they can gain as much money as possible. Using market segmentation could mean a business could gain a commercial advantage as they would be advertising to a specific audience, they would be matching target audience and the product effectively. Demographics are where the companies target market would be to a group because of their Gender, age, race/nationality, family size, occupation and education. For example McDonalds advertise happy meals to children because they would keep bugging their parents to take them to get them it. Geographic’s are where the companies target market would be to a group because of where they live, for example an expensive store wouldn’t come to Burnley because most of the residents are working class and don’t have a lot of money. Psychographics are where the companies target market would be to a group because of personality, lifestyle and interests. For example subway would advertise to people with a healthy lifestyle. These segmentation methods are used to split up the market so business can find the perfect target market, if companies didn’t use these methods then the companies wouldn’t have a good understanding of the people they are trying to advertise to. ACORN or A Classification of Residential Neighbourhoods, is used to segment the market into different classifications, the classifications are split up into 5 categories, which are: †¢ Wealthy Achievers – wealthy people who already have good, well-paid jobs, †¢ Urban Prosperity – wealthy people who are aspiring to have good, well-paid jobs, †¢ Comfortably Off – people aren’t particularly wealthy but have a decent sized house etc. †¢ Hard Pressed lower classed people, who are live in high rise flats etc. Moderate Means – working class people, live in terraces. Another method of segmentation the public are is a system created by Experian called Mosaic, this assigns people to groups based on their post code, neighbourhood etc. and it makes assumptions about peoples likes, dislikes and lifestyles based on their postcode area. †¢ A Career professionals living in sought after locations †¢ B Younger families living in newer h omes †¢ C Older families living in suburbia D Close-knit, inner city and manufacturing town communities †¢ E Educated, young, single people living in areas of transient populations †¢ F People living in social housing with uncertain employment in deprived areas †¢ G Low income families living in estate based social housing †¢ H Upwardly mobile families living in homes bought from social landlords †¢ I Older people living in social housing with high care needs †¢ J Independent older people with relatively active lifestyles †¢ K People living in rural areas far from urbanisation McDonalds target markets are happy meals, saver menu, portion sizes, fillet o’Fish, breakfast and hot drinks; the happy meal is targeted towards children as they will use pester power to make their parents take them to McDonalds. They sell small portions that contain a healthy snack and you get a free toy in them, the toy is themed towards a children’s cartoon film, they normally advertise on nickelodeon, cartoon network and Disney channel because that’s what most children watch. They advertise after 3 o’clock because that’s when most children get home from school as if they advertised before 3 o’clock then not a lot of children would see it; the happy meal would also suit the elderly as they won’t be able to eat a big meal. The saver menu would suit students and people who don’t have a lot of money; it would suit students as they won’t have to spend a lot of money on the larger meals and they can spend it more important things or going out at the weekend. It would suit people who don’t have a lot of money as they are relatively small portions and it is only 99p for a burger so it is a cheap. The portion sizes would be good for when people who aren’t particularly hungry or they are really hungry, as if they aren’t hungry they can get a medium meal, If they are really hungry they can get the large meals. This is good as it creates more of a target market for McDonalds to attract. The Fillet o’Fish as people who don’t like eating meat can get this instead of just getting chips, this is good as well as it McDonalds look like they are family orientated and they don’t miss anyone out. The McDonalds breakfast suits people who have to get up early as they do normal breakfast meals instead of a burger they could get sausage or something else. The hot drinks are good for when it is winter as people won’t want cold drinks as they would want warm drinks like coffee or hot chocolate etc. McDonalds will have a variety of different targets for their products and services. 4 examples can look at: Families: Families are targets as when families go out, they normally go to places that the kids will enjoy as if the kids aren’t happy, then parents will not be happy as they will be seeing their children unsatisfied with where they are. McDonalds will advertise all they can to make it look more appealing to all generations of families, These services aim towards providing friendly environments for the customers to have fun at and enjoy meals at affordable prices. They will be close families, as they will be visiting places with the idea of where is best suitable for the kids and themselves to enjoy themselves. The gender is not again specific as families could be of mixed gender. The age range will be from 1+ as a nice little outing to McDonald’s with the family is always nice. Parents with Children: parents with children will take their child to McDonald’s to give their children a treat. This is a product that McDonalds has produced to attract children between the ages of 1-10, as it has a free toy with the meal it is aiming to attract children and not only will the food be a treat but they will also get a free toy to play with. The target markets for happy meals is the parents buying their children food will be identified as young children ranging from ages of 1-10 as the toys that come with the happy meals look suitable for children of that age. Teenagers: Teenagers usually have limits to how much they can spend on food, As they may have limited pocket money or more important ideas of something they may want to purchase so cannot afford to spend their money on fast food. This is why they are attracted to the saver menu, the saver menu is where you can buy food for a reasonably price. Also teenagers are known to be the main users of social networking sites and users of the internet, so the idea of free WIFI access available in their restaurants is also another way to attract people to their restaurants. So, the target market for the saver menu will be identified as someone who wants to enjoy McDonald’s at an affordable price and the target market for the free wifi will be mainly teenagers as a stop at a restaurant for a quick check of their social networking sites will tempt them to buy something quick to enjoy whilst they are in the store. The age range for both the saver menu and WI-FI will be from 16+ as people from the age of 16 + are identified to be the age range of social networking sites and the saver menu is for everyone. Local Workers: Whilst on their breaks; local workers may pop in to the closest McDonalds, they have nearest to them to have a hot meal as it’s usually served very quickly and this makes it very efficient for the workers as they may have a short break. The lifestyle of these regular workers will be busy as they are working and may not have enough time in mornings to prepare dinner before they leave so they visit cafe/restaurants that are close by to eat in at and then head back to work. Also, they will need reasonable prices as they may have budgets for their dinner/meals. Gender of local workers will also not be specific in this case as you can be of any gender to have a job. The age range will be that of 18+ to about 65, as 18 is the age you most people start working and usually people retire at 65 and are not likely to be regular customers, as fast food places as due to being older than maybe teenagers, they have to be more careful with their diets as they can be more affected easily health wise with regular takeaway consuming. A Business Person: a business person will visit McDonalds during the morning, maybe for a brew or the breakfast, Also their food can be eaten in a vehicle without it affecting a busy work schedule, as they can use the drive thru, McDonalds have many drive thru’s which is a service that makes it efficient for people that may not have enough time to eat in to enjoy their products in their vehicles. The target market for a drive thru will be busy people that do not have enough time to eat in. The gender for business customers will be both male and female as in the modern world. The age range of established and busy business people is most likely to be about 30+.

Factors Affecting Postharvest Quality of Fresh Fruits

Factors Affecting Postharvest Quality of Fresh Fruits A ripened ovary of a flower together with any accessory part associated with, is referred to as fruit (Lewis Robert 2002). In non-technical usage the term fruit normally means the fleshy seed-associated structures of certain plants that are sweet and edible in the raw state, for example apples, oranges, grapes, strawberries and bananas (Mauseth James, 2003). Fresh fruits and vegetables are living tissues which undergo continuous changes after harvest. Some of these changes are desirable, but from consumers point of view most of them are undesirable. It is not possible to stop the postharvest changes in fresh produce, but they can be retarded within certain limits (Kader, 2002). There are several atmospheric factors which affect the postharvest life of fresh fruits. Climatic conditions, specially temperature and light have a significant effect on the nutritional quality of fresh fruits and vegetables (Kader, 2002). FACTORS AFFECTING THE POSTHARVEST LIFE OF FRUIT RESPIRATION Respiration is the process by which stored organic materials are broken down into simple end products with a release of energy. During this process oxygen (O2) is consumed while carbon dioxide (CO2) is produced. All living organisms must carry out respiration at all times (Kader, 2002). Respiration Metabolism Even after the harvest, fruits and vegetables remain as living organs. Like all living tissues, harvested produce continues to respire throughout its postharvest life. The main purpose of respiration is to maintain sufficient supply of adenosine triphosphate (ATP).The process of aerobic respiration involves the regeneration of ATP from ADP (adenosine diphosphate) and Pi (inorganic phosphate) with the release of CO2 and H2O. In case of hexose sugar the overall reaction can be written as (Kader Saltveit, 2003) The different components in this reaction have different sources of destinations. The 1 mole of glucose (180g) can come from stored simple sugars (glucose, sucrose) or complex polysaccharides (starch). The 6 moles of O2 (192g) used to oxydize the 1 mole of glucose diffuses into the tissue from the surrounding atmosphere, while the 6 mole of CO2 (264g) diffuses out of the tissue. The 6 mole of water (108g) produced is simply incorporated into the aqueous solution of the cell.(Kader Saltveit, 2003) Aerobic respiration involeves a series of three reactions, each of which is catalyzed by a number of specific enzymes that either (i) add a phosphate group to a molecule, (ii) rearrange the molecule, or (iii) break down the molecule to a simpler one ((Biale, 1960);(Davies, 1980)). The three interconnected metabolic pathways are glycolysis, the tricarboxylic acid (TCA) and the electron transport system. Glycolysis The breakdown of glucose occurs in the cytoplasm, which produce two molecules of pyruvate. 10 different sequential reactions are catalysed by one enzyme. Phosphofructokinase (PFK) is the main enzyme in Glycolysis, which cleaves fructose 1, 6-diphosphate into two triose phosphate molecules. By controlling PFK activity of Glycolysis, cell can control their rate of energy production. ATP is used as a negative feedback inhibitor to control the activity of PFK (Davies, 1980). Besides pyruvate, Glycolysis also produces two molecules of ATP and two molecule of NADH (reduced nicotinamide adenine dinucleotide) from the breakdown of each molecule of glucose. Tricarboxylic Acid (TCA) Cycle The TCA cycle occur in mitochondrial matrix, involves in the breakdown of pyruvate into CO2 in nine sequential enzymatic reactions. Pyruvate is decarboxylated to form acetate, which condenses with a co enzyme to form Acetyl CoA. This compound then enters the cycle by condensation with oxaloacetate to form citric acid. Citric acid has three carboxyl groups, from which the cycle derives its name (Kader Saltveit, 2003). Through a series of seven successive rearrangements, oxidations and decarboxylations, citric acid is converted into oxaloacetate, which is then ready to accept another acetyl CoA molecule. The TCA cycle also produces one molecule of FADH2 (reduced flavin adenine dinucleotide) and four molecules of NADH for each molecule of pyruvate metabolism. Electron Transport System The electron transport system occurs in the cristae of mitochondria, results in the production of ATP from the FADH2 and NADH. The energy produced is more than the cellular process requirement. In a series of reactions, one NADH molecule produces three ATP molecules and one FADH2 molecule produces two ATP molecules, but the exact number of ATP produced during electron transport depends not only on the energy of NADH and FADH2 but also on the chemical environment within the cell and mitochondria. In the absence of O2, NADH and FADH2 accumulates, the TCA cycle stops and Glycolysis become the only source of ATP production. In anaerobic respiration hexose sugar is converted into alcohol and CO2 in the absence of O2. Pyruvate produced in Glycolysis is decarboxylated by the enzyme pyruvate carboxylase to form CO2 and acetaldehyde. The acetaldehyde is converted by the enzyme alcohol dehydrogenase to ethanol with regeneration of NAD+. Two moles of ATP and 21 kcal of heat energy are produced in anaerobic respiration (alcoholic fermentation) from each molecule of glucose (Kader Saltveit, 2003). Respiration Quotient (RQ) The respiration quotient (RQ) determines the amount of substrates utilized in the respiration process. In other words RQ is the ratio of CO2 produced to O2 consumed measured in mole or volumes. In the aerobic respiration of carbohydrates the RQ is near 1, while is 1 for organic acids. Very high RQ values usually indicate anaerobic respiration in those tissues which produce ethanol. GAS EXCHANGE Barrier to Diffusion Gas exchange between a plant organ and its environment follows Ficks first law of diffusion. The sequential steps are (i) diffusion in the gas phase through the dermal system (i.e. cuticle, epidermis, stomata etc.); (ii) diffusion in the gas phase between the intercellular spaces; (iii) exchange of gases between the intercellular atmosphere and the cellular solution (cell sap) and (iv) diffusion in solution within the cell to centres of O2 consumption and from centers of CO2 production. This exchange is a function of the resistance of the dermal system to gas diffusion, the surface area across which diffusion can take place etc. CO2 produced within each cell will raise the local concentration and this will drive diffusion of CO2 outward, toward the lower concentration near the cell-wall surface adjacent to the intercellular space. Diffusion of CO2 into intercellular space continues toward regions of lower concentration until it reaches the intercellular space below the dermal system. From there, CO2 moves through the cuticle or openings in the commoditys surface to the air (Burton, 1982). Movement of O2 within plant tissue is in a reverse but similar process to that mentioned above for CO2. In senescent tissue, O2 diffusion may be slowed down if the intercellular spaces become filled with cellular solution that anaerobic conditions develop within tissues. The rate of gas movement depends on the properties of gas molecule and the physical properties of the barriers (thickness, density etc.). Solubility and diffusivity of each gas are important for its diffusion across barrier. CO2 moves more readily than O2, while diffusion rate of C2H4 and CO2 are similar. Internal concentration of CO2 and O2 in plant organs depend upon the maturity stage at harvest, the current organ temperature, the composition of external atmosphere and any additional barrier. Maturity stage influences the dermal system that effects gas diffusion. Increased temperature results raised rate of respiration as a result internal CO2 level increases as the O2 level decreases. If all other factors are held constant and the movement in the gas concentrations is the driving force for diffusion, then the concentration of O2 and CO2 within the tissue will fluctuate according to the fluctuation in the external atmosphere. Methods to Alter rates of Gas Exchange There are three types of barriers to gas exchange that affect the postharvest handling of fresh produce (Fig. 1). These are (i) the structure of the dermal system such as thickness of cuticle, number and distribution of stomata and breaks in epidermis etc. Resistance to gas diffusion can be increased by adding barrier such as wax coating or covering produce with polymeric films. (ii) The package in which the commodity is shipped can be additional barrier to gas diffusion. (iii) The degree of gas tightness of the transit vehicle or storage room will also affect gas exchange with outside air. Schematic model of a commodity and its environment with three levels of gas exchange: B1=structure of dermal system and added barriers (waxing and film wrapping), B2= Permeability of package to gas diffusion, and B3 = gas tightness of the storage room Source: (Kader Saltveit, 2003) Ficks first law of diffusion states that the movement or flux of a gas in or out of a plant tissue depends on the concentration gradient across the barrier involved, the surface area of the barrier and the resistance of the barrier to the diffusion. Ficks law can be written as follows: J = A. ΆC/R Where J =Total flux of gas to be diffused (cm3.s-1) ΆC= Concentration gradient across the barrier A=the surface area of the barrier R= Resistance to diffusion If the production or consumption rate of the gas by the organ and the concentration of the gas in the internal and external atmosphere is known, then the resistance is calculated as follows: R = Concentration gradient/ Production or consumption rate Different harvested fruits and vegetables have different rates of respiration; some respire at a faster rate (more perishable), while some respire at a relatively slow rate (less perishable vegetables) (Table 1). Table 1: Classification of Sample Horticultural Commodities According to Respiration Rates (Wilson, 1999). Respiration Rates Types of Fruits and Vegetables Very Low Dried fruit and nuts Low Apples, garlic, grapes, onions, potatoes (mature), sweet potatoes Moderate Apricots, cabbages, carrots, figs (fresh), lettuce, nectarines, peaches, pears, peppers, plums, potatoes (immature), tomatoes High Artichokes, Brussels sprouts, cut flowers, green onions, snap beans Extremely High Asparagus, broccoli, mushrooms, peas, sweet corn The process of respiration is very important during ripening of fruit. In general there is an inverse relation between the rate of respiration and the postharvest life of fruit. Postharvest produce are classified according to their respiration rate as climacteric or non- climacteric. The rate of respiration increases in climacteric fruits during ripening while non-climacteric fruit shows no change in their low CO2 and ethylene production rates during ripening (Kader, 2002). If prevention or decrease in respiration is achieved, this will prolong post-harvest storage life. Ethylene causes the increase in respiration, so decreasing ethylene is also a strategy used to increase post-harvest storage life. Factors affecting respiration rate Environmental Factors Temperature Temperature is important environmental factor in the postharvest life of fresh produce due to its outstanding effect on rates of biological reactions, including respiration. Within the physiological temperature range, the velocity of biological reaction increases two to threefold for every 10  °C rise in temperature (Vant Hoff rule). The ratio of reaction rates at two dissimilar temperatures is called the temperature coefficient (Q10) if the interval between the two temperatures is 10oC. If the temperature interval of Q10 is not exactly 10o C then it can be determined by the following equation: Q10 = (R2/ R1) 10/T2-T1 Where R2 = rate of respiration at T2 R1 = rate of respiration at T1 T1 and T2 = temperature in  °C Scientists have found that Q10 is not constant for most biological processes over a wide range of physiological temperatures. Usually Q10 ranges from 1 to 5, although higher value may occur. For most biological reaction the Q10 is between 2 and 3 for temperature between 10 to 30  °C that means the reaction rate will be double or triple with every 10  °C increase. O2 and CO2 Concentration Practically, respiration can be controlled by either increasing carbon dioxide or decreasing oxygen. Decrease in oxygen near to zero is not desirable, though the O2 concentration reduces below that in air (20.9%) and especially below 10%, a significant reduction in respiration rate is observed (Gorny, 2001). However when O2 concentration drops to less than 2 %, anaerobic respiration rate become predominant and CO2 production increases. (Figure 2) (Kader Saltveit, 2003). Ethylene Concentration Exposure of climacteric tissues during their pre-climacteric stage to ethylene raises the rate of respiration. Once the respiration rise has begun, the endogenous rate of ethylene production increases and the internal ethylene concentration also increases, reaching levels that saturate its biological activity. However, unlike the case in climacteric tissues in non-climacteric tissues endogenous ethylene production remains unaffected (Kader Saltveit, 2003). Internal factors Type of Commodity Fruits and vegetables vary greatly in their respiration rate (Table. 1). Differences among plant parts and in the nature of their surface coatings (e.g. cuticle thickness, stomata, lenticels) influence their rate of diffusion characteristic and consequently their respiration rates. Stage of development at Harvest The respiration rate is usually high at early stages of development and decreases as plant organs mature. Thus fruits and vegetables harvested during the active growth phase have high respiration rates. Chemical Composition Respiration rate decreases with a decrease in water content of the tissue. The value of Respiration Quotient (RQ) is usually controlled by the rate of utilization of carbohydrates, proteins, lipids etc. ETHYLENE PRODUCTION Ethylene (C2H4) is a gaseous hormone produced from bacteria, fungi and all parts of higher plants such as shoots, flowers, seeds, leaves, roots, and fruits (Pech et al., 2003). It is a flammable and colourless gaseous compound (Arshad Frankenberger, 2002). Being a ripening hormone ethylene play a very important role in the postharvest life of many horticultural products, like increasing senescence speed and reducing shelf life but beneficially it improves the quality of the fruit and vegetables by manipulating uniform ripening process (Reid, 2002, p. 149). Because of the enormous influence of ethylene on the physiological development and postharvest life of fruits and vegetables, its biosynthesis, action, and control have been intensively investigated (Reid, 2002; Pech et al., 2003). The biosynthetic process of ethylene is usually completed in three major steps. The ethylene biosynthetic pathway is given in the figure 3. Step I: The biosynthesis of ethylene hormone is started by the conversion of Methionine (MET) to S-adenosyl-L-methionine (SAM) by the enzyme methionine adenosyltransferase (Pech et al., 2003). However, methionine adenosyltransferase is thought to consider as a rate limiting enzyme in ethylene biosynthesis because formation of SAM depends on the activity of this enzyme and SAM levels may indeed regulate ethylene production. Therefore, the sensitivity or importance of methionine adenosyltransferase to SAM implies that this enzyme may play a regulatory role in ethylene biosynthesis (Arshad Frankenberger, 2002, p. 13). Step II: SAM is consequently converted to 1-aminocyclopropane-1-carboxylic-acid (ACC) by a pyridoxal enzyme ACC synthase (ACS) (Figure 1). Actually, before the discovery of ACC, as intermediate, immediate precursor in MET dependent ethylene production process, the ethylene biosynthetic pathway was intangible (Arshad Frankenberger, 2002, pp. 11-50). The conversion of SAM to ACC by ACS is another rate-limiting step in the biosynthetic pathway of ethylene. ACS is a cytosolic enzyme (found in the cytoplasm of plants) (Paliyath Murr, 2008b) and its activity is strongly inhibited by aminoethoxyvinylglycine (AVG) (a competitive inhibitor) and aminoisobutyric acid (AIB) (an inhibitor of pyridoxal phosphate-mediated enzyme reactions) (Arshad Frankenberger, 2002, pp. 11-50). Moreover, the activity of ACC synthase is also influenced by factors such as fruit ripening, senescence, auxin levels, physical stresses, and chilling injury. The synthesis of this enzyme increases with an increase in the level of auxins, indole acetic acid (IAA) and cytokinins (Wills et al., 1998, p. 42). Step III: At last the ACC converts into ethylene by the action of ACC oxidase (known as ethylene forming enzyme or EFE) (Arshad Frankenberger, 2002, pp. 11-50; Pech et al., 2003). However, ACC oxidase is a bi-substrate enzyme as it requires both oxygen and ACC. Moreover, this enzyme also requires Fe2+, ascorbate and CO2 for its activity. Activity of ACC oxidase is inhibited by cobalt ions, and temperatures higher that 35oC (Wills et al., 1998, p. 42). The sub cellular position of ACC oxidase is still a point of controversy because there is a large number of data is available showing that this enzyme is associated with plasma-membrane or with apoplast or tonoplast. The activity of this enzyme (ACC oxidase) has been studied in many horticultural crops like melon, avocado, apple, winter squash, pear and banana. The activity of ACC oxidase is not highly regulated as ACS. It is constituted in most  vegetative tissues and it is induced during fruit ripening, wounding, senescence and fungal  eli citors (Arshad Frankenberger, 2002, pp. 11-50). In fruits and vegetables several metabolic reactions starts after harvesting. In most cases, an increase in biosynthesis of gaseous hormone like ethylene serves as the physiological indication for the ripening process. During ripening process, in some fruits large amount of ethylene is produced which is usually referred as autocatalytic ethylene production response. However, fruits are divided into two main categories on the basis of ethylene production, i.e. climacteric (those produce large amount of ethylene) and non-climacteric fruits (those produce smaller amount of ethylene). In climacteric fruits like apple, pear, banana, tomato and avocado, ethylene production usually ranges from 30-500 ppm/(kgh) during ripening. While non-climacteric fruits like orange, lemon, strawberry and pineapple, produce 0.1-0.5ppm/(kgh) of ethylene (Paliyath Murr, 2008) (Table 2). Therefore application of even a very low concentration of ethylene (0.1-1.0 ÃŽÂ ¼L/L) is sufficient enough to accelerat e full ripening of climacteric fruits; however, the magnitude of the climacteric rise is not dependent on the amount of ethylene treatment. On the contrary, application of ethylene causes a temporary rise in the rate of respiration of non-climacteric fruits and the degree of increase depend upon the amount of ethylene (Wills et al., 1998). Moreover, the difference in the respiratory patterns of climacteric and non-climacteric fruits is associated with the different behaviour in terms of the production and response to ethylene gas (Burton, 1982). The increase in respiration, as influenced by ethylene application, may happen several times in non-climacteric fruits, but only once in climacteric fruits (Wills et al., 1998). Indeed, ethylene is produced by all parts of the plant but the magnitude of ethylene production varies from organ to organ and also depends on the stage and type of growth and developmental process. In fact, recent ethylene based research findings have increased the understanding of biosynthetic pathways and enzymes involved in ethylene production, as well as the development of several ways to manipulate ethylene production e.g. by genetic alteration of plants (Arshad Frankenberger, 2002). Ethylene is produced by various plant parts growing under normal conditions however, any kind of biological, chemical or physical stress (e.g. wounding) strongly promotes endogenous ethylene synthesis by plants. Among stress induced ethylene production, pre-harvest deficit irrigation is one of the most important factor causing higher ethylene production rates in fruits like avocado (Adato Gazit, 1974) and tomato (Pulupol et al., 1996). REGULATION OF ETHYLENE BIOSYNTHESIS In plants, ethylene itself stimulates the ability of the tissue to convert ACC into ethylene, which is also regarded as phenomenon of auto-regulation. In ripening fruits, regulation of ethylene biosynthesis is a characteristic feature and is triggered by the exposure to exogenous ethylene by the activation of ACC synthase and/or ACC oxidase (Arshad Frankenberger, 2002, pp. 25-27). On the other hand, sometimes ethylene inhibits its own synthesis, as negative feedback has already been recognised in a number of fruits and vegetable tissues. In such cases, exogenous ethylene significantly inhibits the production of endogenous ethylene, induced by ripening, wounding and/or treatment with auxins. Moreover, this auto inhibitory effect seems more directed towards limited availability of ACC in the presence of AVG, an inhibitor of ACC synthase (Arshad Frankenberger, 2002, pp. 25-27). Scientists have also revealed that the inhibition or negative regulation of ethylene synthesis is the result of activity of a gene, E8 whose expression leads to the inhibition of ethylene production in tomatoes (Arshad Frankenberger, 2002, pp. 25-27). MECHANISM OF ACTION The response of ethylene action can be classified into two categories namely concentration response and sensitivity response. The concentration response involves the changes in concentration of cellular ethylene while the sensitive response involves the increase in tissue sensitivity to ethylene. Moreover, both of these responses involve the binding of ethylene to some components of the cell to mediate the physiological effects (Arshad Frankenberger, 2002, pp. 28-36). Wills et al. (1998, pp. 42-45) likewise explained that plant hormones control the physiological processes by binding to specific plant or fruit receptor sites, which trigger the succession of events leading to visible responses. In the absence of ethylene, these receptor sites are active, allowing the growth of plant and fruit to proceed. During fruit ripening, ethylene is produced naturally or, if it is artificially introduced in a ripening room, it binds with the receptor and inactivates it, resulting in a series of events like ripening or healing of injuries in plant organs. Ethylene action can be controlled through modification of the amount of receptors or through disruption of the binding of ethylene to its receptors. Binding of ethylene is believed to be reversible at a site which contains metal like copper, zinc, or iron (Burg Burg, 1965, as cited in Burton, 1982). The affinity of receptor for ethylene is high in the presence of oxygen and decreases with carbon dioxide. Changes in the pattern of ethylene production rates and the internal concentrations of ethylene associated with the onset of ripening have been studied in various climacteric fruits. For instance, tomato and honeydew melon exhibited a rise in ethylene concentration prior to the onset of ripening, determined as the initial increase in respiration rate. On the other hand, apple and mango did not show any increase in ethylene concentration before the increase in respiration (Wills et al., 1998, pp. 42-45). Ripening has been associated with senescence as it leads to the breakdown of the cellular integrity of the tissue. It is part of the genetically programmed phase in the development of plant tissue with altered nucleic acid and protein synthesis occurring during the onset of the respiratory climacteric resulting in new or enhanced biochemical reactions operating in a coordinated manner (Wills et al., 2007, p. 40). These concepts confirm the known degradative and synthetic capacities of fruit during the ripening process. The ability of ethylene hormone to initiate biochemical and physiological events leads to the theory that ethylene action is regulated at the level of gene expression (Pech et al., 2003; Wills et al., 1998, pp. 45-46). TRANSPIRATION/ WATER LOSS Plants depend more on the availability of water than any other single environmental factor (Kramer and Boyer, 1995). Water loss is very important in determining the shelf life and quality of harvested plant organs. As long as the harvested produce retains water, it remains fresh. Transpiration is one of the main processes that affect postharvest life of the fruit (Ben-Yehoshua Rodov, 2003) Most fresh produce contains from 65 to 95 percent water when harvested. Within growing plants there is a constant flow of water. Fresh produce continues to lose water after harvest, but contrary to the growing plant it cannot replace lost water from the soil and so must use up its water content remaining at harvest (Gustavo et al., 2003). This loss of water from fresh produce after harvest is a serious problem, causing shrinkage and loss of weight. When the harvested produce loses 5 or 10 percent of its fresh weight, it begins to wilt and soon becomes unusable. To extend the usable life of produce, its rate of water loss must be as low as possible (Wilson et al., 1995). Although temperature is the prime concern in the storage of fruits and vegetables, relative humidity is also important. The relative humidity of the storage unit directly affects water loss in produce. Water loss means salable weight loss and reduced profit (Wilson et al., 1995). Transpiration of fresh fruits is a mass transfer process in which water vapor moves from surface of the plant organ to the surrounding air. Ficks law of mass transfer explains this process as follows: J = (Pi-Pa) At / (RDT)r Where Pi and Pa are the partial gas pressures in intercellular spaces and in the ambient atmosphere respectively; At is surface area of fruit; RD is the gas constant per unit mass; T is the absolute temperature; r is the resistance; and J is the gas flux. According to Ficks law, the movement of any gas in or out of the plant tissue is directly proportion to the partial pressure gradient (Pi-Pa) across the barrier involved and the surface area of the barrier and is inversely proportion to the barrier to diffusion. Therefore the driving force of transpiration is the difference of water vapor pressure (WVP) between the tissue and the surrounding air. While the water vapor pressure deficit (VPD) of the air is difference between the WVP of air and that of saturated air at the same temperature. Relative Humidity is the most popular term for expressing the water content of air. It can be defined as the ration of actual WVP in the air to the saturation WVP at a given temperature. Water loss depends on the difference between the water vapour pressure inside the fruit and the pressure of water vapour in the air. To control water loss in fresh produce as low as possible, it must be kept in a moist atmosphere. Air movement also plays a vital role in the water loss from the fresh produce. Water loss is directly proportion to the air movement in the surrounding. Though air movement through produce is also indispensable to remove the heat of respiration, but the rate of movement must be kept as low as possible (Gustavo et al., 2003). ROUTES OF WATER TRANSMISSION As the harvested fruits and vegetables are detached from plant, the xylem vessels are blocked with air and their operation is stopped (Burton, 1982). Therefore, water has to use different routes to move through the tissue. Following are the major potential pathways for water movement in harvested produce. Symplast The cytoplasm of connected cells is interconnected by plasmodesmata, filled with protoplasm and lined with the plasmalemma. Therefore symplast is formed throughout the interior of a plant organ. Water and dissolved solutes move through the symplast system from cell to cell by diffusion (Ben-Yehoshua Rodov, 2003). Apoplast The cell wall surrounding symplast also form a continuous system, termed as apoplast. The apoplas provide an alternative avenue for liquid water movement by hydrostatic pressure through the interfibrillar spaces in the cell wall (Woods, 1990). Intercellular Atmosphere The plant also contains a system of intercellular gas-filled spaces that form a continuous network and serve as main pathway for O2 and CO2 transport. This field of air space provide adequate gas exchange in bulky organs (Ben-Yehoshua.S, 1969). MAJOR EVAPORATION SITE: COMMODITY SURFACE There are three major routes for moisture loss from harvested commodities to the atmosphere: (a) through outer layer that forms a surface for evaporation (cuticle and epicuticle wax; periderm) resistance for water movement through (b) the apertures in the surface connecting the internal and external atmosphere (stomata, lenticels) and (c) through the stem scars or pedicel. Cuticle and Epicuticular wax This layer, which lines all interfaces between the plant and the atmosphere, protects the plant from its relative dry environment. Resistance to water movement is derived from cuticular layer (Ben- Yehoshua, 1969; (Burg Burg, 2006). The cuticle cosntains a matrix of cellulose, polyuronic acids, proteins and phenolic compounds. These are combined with variation of amount of waxes embedded over its surface (Kolattukudy, 1980). Permiability to water usually depends more on amount of waxes than on the thickness of cuticle (Kramer Boyer, 1995). Periderm Periderm is a corky peripheral tissue. This tissue consists of several layers of cells that become corky as a result of deposition of waxes on their cell walls, and they lose their living contents. The periderm is not readily permeable to water and is permeable to gases only through lenticular pores, which replace the stomata of the original epidermis. About 97% of the total water lost from the potato tubers migrates through cell walls to the periderm, where it evaporates (Burton, 1982). Trichomes and Hairs Unicellular or multicellular projections develop on the epidermis of all parts of plants. Their exact function is still vague, but they are considered to reduce water loss (Cutter, 1976). The presence of trichomes can decrease the driving force of transpiration by reducing the surface temperature and increasing the boundary layer resistance. Stomata Before harvest, most of the evaporation occurs from undersides of leaves via stomatal guard cells and adjacent cells (Kramer and Boyer, 1995). Stomata occur in many fruits at early stages of development, but sometimes they are not found in mature fruits of some species, for example, in the grape berry (Possingham et al., 1967). Orange has greatest stomatal density reported so far for any fleshy fruit (Banks, 1995). Stomata usually function less effectively in mature fruit (Blanke and Leyhe, 1988). In most cases it is reduced with maturation and usually of minor importance for fruit water loss during postharvest period (Ben-Yehoshua Rodov, 2003).

The Ethics of Gene Therapy Essay -- Genetics Science Papers

The Ethics of Gene Therapy Francis Crick was quoted as saying, "We used to think that our fate was in our stars. Now we know that, in large measure, our fate is in our genes." Over 40 years ago, James Watson and Francis Crick discovered the structure of deoxyribonucleic acid (DNA). From this a new technique has evolved called gene therapy. Gene therapy was discovered in the 1980’s a few years after researchers were already able to isolate specific genes from DNA. These techniques matured from the massive surge of ideas generated during the Recombinant DNA (rDNA) era. Gene therapy is basically the repairing of genes to correct for diseases that result from a loss or change in our genetic material. It is hard to comprehend the total effects of gene therapy, because we do not know if it should really be used? Who does it really benefit? And ultimately people can easily contemplate how it affects him or herself and their family. Therefore, to understand gene therapy some technical aspects need to be discuss ed. Technical aspects DNA is present in the nucleus of cells and is the genetic information of all organisms. The information of a human genome could be thought of in terms as an "encyclopedia", the 23 chromosome pairs would be "chapters", each gene a "sentence", three letter words "codons", which are spelled by each letter a "molecular nucleotide"--adenine (A), cytosine (C), guanine (G), and thymine (T) (Elmer-Dewitt, 1994). A gene acts as a blueprint and if these were blueprints for a house and the measurements were off by a foot, it has a huge influence on its total structure. This is the same for our bodies, if a slight alteration in our genetic information occurs like a mutation this could lead to a disease. D... ...tad. 1991. Principles of genetics. 8th ed.

Crime and Punishment :: essays papers

Crime and Punishment In the novel Crime and Punishment, by Fyodor Dostoevsky, suffering is an important part of every character’s role. However, the message that Dostoevsky wants to present with the main character, Raskolnikov, is not one of the Christian ideas of deliverance through suffering. Rather, it appears to me, as if the Dostoevsky never lets his main character suffer mentally throughout the novel, in relation to the crime that is. His only pain seems to be physical sickness. I chose literary criticism from The Times Literary Supplement, The Literary World and criticism by Lafcadio Hearn, Oscar Wilde and D.I. Pisarev, because they all deal with the issue of how the main character, Raskolnikov, dealt with the crime that he has committed. â€Å"Raskolnikov does not commit the crime because, by way of varied philosophical considerations, and necessity. On the contrary, the conditions he must live under drive him to commit the crime as they have moved him to philosophize about his intentions. In short, Raskolnikov makes the theory up for his own convenience† (Pisarev, 135). I chose this quote because it is a good way to express how and why Raskolnikov would commit this murder. Raskolnikov commits a thought-out murder in a state of delirium. He ends up committing a second murder, which he never wanted to be responsible for. He kills Lizaveta, an exceedingly innocent person. But does Dostoevsky every remind us of the murder at any time in the novel again? Not in the physical sense of the crime itself. You as the reader doesn’t ever hear about how heavily the murders are weighing on his heart, or how he is tormented by visions of the crime. Raskolnikov doesn’t feel the least bit guilty about having committed the crime; only his pride is being hurt. He doesn’t mention the idea of the pain that might arise from recurrent visions of the crime. Raskolnikov never again recalls the massive amount of blood everywhere, the look on Lizaveta’s face when he brings down the axe on her head. These things clearly show that the crime isn’t what might cause his suffering or pain, it is something else. After Raskolnikov is sent off to Siberia, he doesn’t feel regretful. He grows depressed only when he learns of his mother’s death. He still hasn’t found any reason to feel remorse for his crime.

Drivers Essay -- essays research papers

Drivers   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Trying to sort out what type of driver a person might be is an extremely challenging task. In a person’s own mind, they think they are the aggressive type of driver, or the cautious type, but no one will ever admit that they are the “I got my license in a cracker jacks box driver';. The only fact that is certain about a person is they are never always aggressive or cautious while they drive. A person’s driving type varies from time, place, and, the most important reason, their attitudes affect one’s driving style.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The roads today are filled with all types of drivers, but one of the worst drivers is the hot shot or aggressive drivers. All the time, day after day, people encounter these maniacs, who drive like they think they are invincible. The short period of time that I have been driving, I have encountered some crazy drivers. The first hotshot driver I saw, was actually two teens who were drag racing down the streets going ninety mph or faster. While they were racing, one of the two cars was actually driving on the opposite lane. Other experiences I have encountered were a high performance bike that was weaving in and out of cars just because he didn’t want to stop. This biker was going real fast for what he was doing he reminded me of a cop chasing a robber movie of just how fast the bike was ...

Chapter

Why? Found it really interesting that Gerry had Stan tell so many early recollections in a row without spending time talking about them individually. This technique makes sense so that the stories form a pattern, but it was surprising to me. The most interesting aspect of the early recollections that Stan spoke of, was that he felt that all the past memories were not as emotional as the one with the kitten. I would have expected being yelled at in very memory would have been a saddening realization.But, the memories, other than the one about the kitten, were ones he had already thought about prior to the session, so maybe he had already processed the emotions of them in a way. If you were counseling Stan from this particular theoretical framework, what is one additional technique you might use? What would you hope to accomplish with this intervention? I would have encouraged Stan to make the connection of his memories of his parents being all filled with anxiety and yelling, and ask if those memories reflect anything in his current relationship with them.If you were the client, how would you be likely to respond to the therapist's (Jersey's) comments and interventions in this particular session? If I were Stan would have been very interested in the connections between my early memories and my present life. I would be exited to write down more memories in hopes of finding even more connections to current views, thoughts, or habits. Connections, like these, are fascinating. Chapter After the plague had already been unleashed in Europe, one of the first reactions was people believing that God had unleashed the deadly disease, as depicted in Giovanni Ceramic's (Doc 3) illustration of angels, coming down from the heavens, delivering their arrows of death unto the people. Sarcasms acknowledges that some people were able to escape the arrow of the Black Death in the description of his illustration. As an apothecary, it makes sense hat he views the plague as being delivered by arrows, because normally disease does not affect everyone.Disease, like arrows bypass those who are immune and strike those that are not immune. Another depiction of the plague by an anonymous source (Doc 6) illustrates that a divine entity was delivering the plague to those on earth. The common belief that God caused the plague shows how many people were religious and believed in God and thought that He was punishing them. An alternate view of the plague was blame. Many people blamed the Jews, hill others blamed God and beat themselves in hopes of God intervening. Biochip (Doc 2) discusses that people would torture themselves, the Flagellants, in hopes of God's mercy.This response to the plague was very erratic but somewhat logical because even though they beat themselves, it was for a reason, a call for God's help. With a humanistic point of view, Biochip believes that there is a more scientific approach to conquering the plague instead of hoping God will come down from the heavens and intervene and help the Flagellants. On the other hand, many people blamed the Jews, for instance when they were cremated in Strasbourg, Germany on Valentine's Day (Doc 7) where the Jews were alleged to have poisoned the water supply, in which case they were all burned.This response was made out of hatred, the Jews were a scapegoat because no one really knew how the plague came to be. Many people acted angrily and erratically in hopes Of ending the plague which ended in even more death. Th e Black Plague had a major effect on the population in Europe at the time it ravaged through the continent. The pre-plague population (Doc 9) in Europe was approximately 83 million, but after the plague ran its course, the population subsequently decreased to 60 million.The plague had a major pros and cons to it. A pro would be the fact that it led to the Renaissance Era; while a con would be the major loss of life in Europe. The most popular place of death or where most people died (Doc 8) would be the Holy Roman Empire followed by France. The significance of the amount of death in these two areas is important because it allows us to recognize that these two areas had he worst overpopulation, living conditions, famine, or economic depression over all of Europe.Even though the plague was a traumatic and insane experience for those who lived through the Bubonic Plague, but without the plague, perhaps the most important era that led to the spread of information, knowledge, and prosper ity. People today are able to look how people during the plague responded to disease and now are able to use their reactions to guide future reactions and help resolve the problems people faced back then. Chapter State diagram shows the states of the objects and how those states change. Sequence diagram only shows the message interactions among the objects. 4. Mention and describe three different views used in architectural design. Architectural design is a high level view of the system. It can be described with: logical view : represents the decomposition of a system and how those parts work with each other physical architectural view: represents the mapping of the software to the hardware process view: represents the run- time â€Å"processes† and flow of the system. 5.What is the difference between data modeling and logical data base design? In data modeling we are instructing and showing the Entity-Relationship among the objects. In logical data base design, the E-R diagram is converted to the sets of tables and relationships among the tables. 6. What is the difference between low fidelity prototypes and high fidelity prototypes? Low fidelity prototypes are quick hand drawn screens using markers, post-it notes, post cards, and/or cut out images to represent the screens of the system. Simple mockup sketch of the target product.High fidelity prototypes are screens created using a tool to design the screens. These screens look and mimic the behavior of the future screens of the system. An example of a tool is visual basic with the use of hide and show. Detailed mockup resembling and behaving close to the final product. 7. Discuss Figure 7. 26 with regard to the user's interaction; the screen's interaction; and the system's interaction (process). The user sees the Registration Screen for the Spring 2012, using the drop box â€Å"All Courses† they would select a course and click the button â€Å"Add Course†.The screen would show the representation seen at the top of Figure 7. 26 initially. This screen would react to the user's usage of the drop box (showing a scrollable list of he available courses and showing the course selected). When the user has selected a course and clicked â€Å"Add Course' the screen would send the information to the registration and when the Registration returns success it would show the second screen in Figure 7. 26. The system's interaction shown in Figure 7. 26 begins with the Registrations object passing the registration information to the section object.This section object needs to check if the student has the prerequisites for the course. If the Boolean returned is True then the message Add(student) is sent to students object. Note: another sequence diagram would represent Boolean = False. 8. Explain â€Å"Adding a course† from section 7. 3. 4. 1 using Normal's 7 Stage Model. 1 Form a goal -? add Engle 201 1 – The user (student) forms the goal â€Å"l need to add Engle 2011 to my schedule†. 2 Form an intention – find Engle 201 1 The user (student) forms the intention on the screen shown in 7. 26 to find Engle 201 1 in the drop box. Specify the action – mouse can show courses in the drop box – The user will decide to use the mouse to click and hold open the drop box and move the mouse down until he/she sees the Engle 2011 course. Execute the action – The user moves the mouse to the arrow in the drop box and clicks when he/she is on the arrow of the drop box. 5 Perceive the system state (feedback) – he/she sees the drop box open with multiple courses in a list. 6 Interpret the feedback – he/she sees the Engle 201 1 7 Evaluate – because the user sees the course they evaluate â€Å"Success† to their intention.Note: They would continue with the next intention to click â€Å"Add Course†. 9. List the four components of the GYMS model for user interfaces. The 4 factors of GYMS model are : Goals, Operators, Methods, and Selection Rules 10. Explain how the Model-View-controller architectural style is done using HTML-Script-SQL. The Model-View-Controller (MFC) architectural style is done with HTML as t he View of the system and SQL as a database. The database has the model of the system. PH is the script used as the controller for the system. Chapter 8: 1 .Question: What are the two general characteristics of a design that naturally carry over from requirements? Answer: The design is an evolution from requirements. So the two general characteristics of a) consistency and b) completeness of requirements usually carry over to the design. 2. Question: What is Menace's climatic complexity number a) attempting to measure, and b) what is the climatic complexity number of a program A that contains 3 binary predicates (or branches)? Answer: a) Menace's climatic complexity number measures the control flow complexity of software. ) Using the simple formula of (#if binary branches + 1), the climatic number of program A is (3+1 ) or 4. 3. Question: What is a program slice? Answer: A program slice is the set of statements that can affect the value of some specified variable of interest in the program. 4. Question: What are glue tokens and super glue tokens, and which type nutrients more to cohesion? Answer: Glue tokens are data tokens that lie in more than one data-slice, and super glue tokens are data tokens that lie in every data-slice. The super glue tokens contribute more to cohesion because they lie in every data slice. 5. Question: What is software cohesion?Answer: Cohesion is a characteristic that describes the degree of relatedness within the software. 6. Question: What are the levels of cohesion? Answer: There are 7 levels of cohesion listed in the order of worst to best: coincidental, logical, temporal, procedural, communicational, sequential, and national. 7. Question: What is software coupling? Answer: Coupling is a characteristic that describes the degree of interdependence or interaction among the parts within the software. 8. Question: What are the levels of coupling? Answer: There are 5 levels of coupling listed in the order of worst to best: content, com mon, control, stamp, and data. . Question: What are the six design measurements of C-K metrics in 00? Answer: They are a) weighted number of methods per class, b) depth of inheritance tree of the class, c) number of children of a class, d) coupling between objects, e) number of espouses to a class message, and f) lack of cohesion among methods in a class 10. Question: In contrast to general design, what is user interface design interested in? Answer: The general software design is concerned about the software components, their characteristics and their interactions.User interface design is focused on the interaction between the software and its human users; thus both software and human attributes are of concern in user interface design. 1 1 . Question: List four out of the eight rules of user interface design identified by Seminarian and Pleasant. Answer: There are actually 8: a) consistency, b) roved short cuts, c) informative feedback, d) closure in dialogues, e) simple error hand ling and prevention, f) permit â€Å"re-do†, g) support locus of control, h) reduce the amount of short-term memory needs. Any four of the eight would be fine. 12.Question: What are the general cohesion and coupling goals when designing software? Answer: We strive for lesser or looser coupling of software, and we design for stringer or tighter cohesion. 13. Question: What is the Law of Demeter attempting to achieve? Answer: Law of Demeter is a set of guiding rules that limits the span of control of an object y restricting the messaging structure among methods of a class. Through these restrictions it is conjectured that we can reduce coupling and enhance cohesion. 14. Question: What is fan-in and fan-out, and what attribute do they measure?Answer: Fan-in is a measure of number of information flow into a module or component. Fan-out is the number of information flow out of a module. An example of fan-in for module-x would be the number of modules that call module-x and for fan -out of module-x would be the number of modules that are called by module-x. Thus fan-in and fan-out measure the coupling attribute among modules. Chapter 9: 1. Question: is the act of transforming the detailed design into a valid program in some programming language.

Chapter In 1 966 the gate ticket revenues mainly paid for player's wages and with the commercial television of Ames global audiences and fan bases grew. In 2009 clubs such as real Madrid, Manchester united and Barcelona became lucrative deals for investors. However, the investment model for football clubs changed and many investors started leveraging the investments through massive amounts of debt. Many clubs in the UK were public limited companies and were listed on the stock exchange but recently many have been brought into private ownership again through private equity.Bankruptcies and corruption scandals have raised questions to whether many football clubs have been able to have a smooth transition into the repressions business world. A clubs livelihood is directly related to their fan base (spectators, TV audiences, or consumers of merchandise) but over the past decade the average attendance to the English Premier League matches has stagnated and younger people have been wary to attend. With high prices for tickets, fans have been feeling alienated by the players' wages and TV scheduling has greatly fuelled the feeling that football is no longer a fan's game but a business oriented way of generating revenue for owners. Between 1 996 and 2006, the seventy-two clubs of the English Football League add a pre-tax loss of IEEE m; in comparison, the other leagues clubs, that were predominantly owned by fans, made Emma operating profit through higher attendance at lower ticket prices.Recently initiatives, such as Supporters Direct, have addressed the fans' interests more directly. They have also been involving themselves in various social projects in the community (usually addressing social exclusion, unemployment, or anti-social behavior). These clubs have created community schemes that often partner with fans, police, and local council. However, clubs such as Real Madrid and FCC Barcelona are member-owned, democratic, and not-for-profit organizations and have leaderships that are accountable to the people who watch and pay.The All party Parliamentary Football Group published three recommendations to improve governance in the industry, these included: A ‘fit and proper persons test' for the management and ownership of clubs Supporter-led governance and, Nurture Eng domestic talent. With these recommendations given, a Stewardship Scorecard, developed by CAR think-tank tomorrow's company, ranked clubs on various criteria such as putting the club first' and â€Å"engagement with fans and the community'. Overall football is still dependent on a constant fan base since they are far less likely to switch allegiances due to poor performance.Ethical Dilemma: Who cares whose shares? 1. What is the main ethical issues in this case? The main issue is whether or not you should tell Freddie to sell his shares of Parchment (PC) because there will be a report published in Big Science magazine that could effect that shares negatively. This is considered insi der trading and is illegal. There are four main ethical arguments that used against insider: fairness, misappropriation to property, harm to investors and the market and undermining of fiduciary relationships (Crane & Matted, 2010).By telling Freddie, you would be giving himself and his clients an unfair advantage over other investors, he would also give up information of PC's privately documented information and knowledge without PC knowing meaning that he is BPCS property is being shared without knowledge. Harm would come to investors and the market because if everyone of Fireside's linens decide to sell their shares then other investors' stocks would decrease and leave others, including the company, wondering why the stocks dropped so much before the release of the report.Your fiduciary responsibility to the company and other shareholders should be one of the most important things since you are an employee of PC as well. 2. Who are the main stakeholders here, and how would you co mpare the relative importance of their stakes? The main stakeholders in the company are the shareholders the employees that don't have shares and the product users. From a humanitarian respective, the product users, whose health and safety are at risk by using product, would be considered the most important stakeholder, and then followed by the employees and then shareholders.From the business aspect the shareholders are the main stakeholders and then the employees and the product users would equally important. This is because the company will most likely not notice a change if a small amount of customers stop using the product. 3. Explain how you would ultimately decide and why. Would not tell Freddie about it because I would rather have a friend mad at e then to end up going to jail/be fined for insider trading by the company. Loud also not tell him because if it were to get out then my reputation for good work habits and judgment would be affected if I ever looked for another job or wanted to be promoted within PC. 4. Is there a difference between acting yourself on the information you were given and passing this information on to Freddie. Yes there is a difference because you aren't sharing company information with anyone so if you do end up selling your shares, and the stocks do not go own, then you would only be hurting yourself and not effecting other investors.

The Accredited Compromise included 6 amendments and 4 congressional resolutions to guarantee permanent slavery. He did this in order to avoid war. 4. Lincoln did what he did in order to not be the first party of the war to take action. He did it to also escape the situation they'd been trapped in for several months. . 6. The National Bank Act of 1 865 established a system of national banks of which eventually developed the banking system we have today. It was important because it encouraged a national currency. 7. From the beginning, it was expected to be a short and low funding war. Walt that being said, the initial (first) war funded by borrowing but eventually realized that it was much more, so they created the Revenue Act of 1862 which increased taxes drastically including federal income taxes which infuriated supporters Of the war. 8. The government raised the majority of it's money by Revenue tax stamps. . The majority of the Northern nation was not supportive at all; riots occasionally occurred. They saw these laws to be an intrusion of privacy and a violation of one's sovereignty. 10. One could avoid by buying their way out of being drafted, or even substitute themselves with another member of their household. 11. Lincoln considered certain parts of the constitution to be â€Å"inconvenient,† in turn often ignoring those specific portions and did what he thought needed be done rather than consulting with congress as to what the constitution states and/or implies should be done. 12.The peace democrats ere a group of people of which believed the North pushed the South to secession. They also believed Lincoln was a tyrant and that the war was a national tragedy. This group was present in the mid-west section of the US including Ohio, Indiana, and Illinois. 13. A. ) He justified the suspension by claiming it was in respect of those arrested. B. ) Everyone' rights were affected as it limited citizens to have an opinion that wasn't supporting the government. 14. Chief Justice Tangy issued this writ, or formal written order, requiring him to release an imprisoned Maryland secessionist leader. Lincoln swaggered this request. 5. The Confiscation Act declared that all slaves that were used for â€Å"insurrectionist† purposes would be considered freed. The second Confiscation Act declared to free the slaves of the persons aiding and us porting the insurrection (regardless of if the slaves were doing so) and also authorized the president to employ African Americans, including freed slaves, as soldiers. As a result, with the progression of the war, the North grew to be more accepting Of emancipation. By the end Of the Civil War, slavery had been abolished i n two Union slave states and in three Confederate dates occupied by Union forces. 16.The Emancipation Proclamation was the war power act Pres. Lincoln issued on Jan. 1, 1863. This act declared forever free slaves in all areas of the Confederacy aside from those already under Union control (Tennessee, western Virginia, and southern Louisiana). It also did no apply to border slave states. 17. Slaves were often taken from their designated plantations and transported to the front, escaping Northern lines, unable to be returned to their masters. Some slaves joined the Union army, while others stayed with troops to flee to free states. Antislavery impulse gained strength, regardless of the act's inability to affect certain areas. 8. About 1 86,000 emancipated African Americans served as soldiers, sailors, and laborers for the Union forces. It was only the first few months of the war that African Americans were widely excluded. They were treated very poorly. Many died from disease due to w orking in unsanitary conditions for arduous hours. Black soldiers were paid a third less in comparison to white soldiers, as well. 19. Women were often put in nursing positions whether it'd been by choice or necessity. They also worked as retail sales clerks, office workers, and mill & factory hands.Shallowness' wives often became responsible for managing slave work forces; the wives Of more modest farmers plowed fields and harvested crops. These were all positions previously dominated by men. 20. Although there were several significant exceptions, the Federal government and the Confederate government were very similar (These exceptions included the acknowledgment of the sovereignty of the individual states, and the sanctioning of slavery [of which made abolition nearly impossible]). 21 . The region focused so intensely on producing cotton and other export crops.The departure of so many white males severely diminished the region's ability to maintain food production. Copious amounts of doctors were conscripted to serve the needs of the military, of which left many communities without any medical care. In effect, the South experienced shortages of everything. Because of this, along with inflation, there was a major instability in Southern society. Resistance to conscription, food impressments, and taxation increased throughout the Confederacy, as well as hoarding and black-market monomer. 22. While raising their armies, many more white Southerners were exempted from military service than Northerners.Conscription was successful for a period of time. Although, after 1862, conscription began to produce fewer men. In early 1864, the government experienced a shortage of manpower. At this time, situations called for desperate measures; the Confederate congress began drafting men as young as 1 7 and as old as 50. 23. The North's economy was strengthened, thus increasing industry and railroad development. The South's was weakened because of millions of Lars worth of pr operty being destroyed and the region's young male population having depleted. 24.The production of weapons was more efficient due to technological advances. Weapons were also stronger and more powerful. 25. A. ) The first battle occurred on July 21, 1861. This battle nearly succeeded in dispersing the Confederate forces, but was unable due to the Southerners taking action in stopping a last strong Union assault and performing a savage counterattack. As a result, the Confederates retreated in an unrecognized manner. When disorganized, as the Union forces were by feat with a short of supplies and transportation, the Confederates did not pursue.Because of this battle, the Union's morale and the president's confidence in his officers were destroyed. B. ) The battle of Animate began on September 17. Mescaline's 87,000-man army attacked Lee's force of 50,000. 6,000 soldiers died, and 1 7,000 sustained injuries. At the end of the day, as the Confederate line seemed ready to break, the las t of Jackson's troops arrived to reinforce it. McClellan then allowed Lee to retreat to Virginia. This battle only lasted one day. C. ) There were complications for the Union forces n the East, but important victories occurred in the West.Grant moved his his and supplies to an area south of the city. He then attacked Vicksburg from the rear. Vicksburg surrendered 6 weeks later on July 4, due to the fact that residents were starving as a result of a prolonged siege. D. ) Lee attacked Mead's army once they were perched on the hills south of the town. Lee's forces Were outnumbered 75,000 to 90,000 and his assault On the Union forces on Cemetery Ridge failed. The next day he ordered a second, larger effort. 1 5,000 Confederates advanced nearly a mile while being swept by Union fire. Chapter First Pages editor of the Harvard Business Review, noted that organizations must also undergo significant efforts to protect their human capital. A firm may â€Å"diversify the ownership of vital knowledge by emphasizing teamwork, guard against obsolescence by developing learning programs, and shackle key people with golden handcuffs. â€Å"23 In addition, people are less likely to leave an organization if there are effective structures to promote teamwork and information sharing, strong leadership that encourages innovation, and cultures that demand excellence and ethical behavior.Such issues are central to this chapter. Although we touch on these issues throughout this chapter, we provide more detail in later chapters. We discuss organizational controls (culture, rewards, and boundaries) in Chapter 9, organization structure and design in Chapter 10, and a variety of leadership and entrepreneurship topics In Chapters 11 and 12. Human Capital: The Foundation of Intellectual Capital Organizations must recruit talented people?employees at all levels with the proper sets of skills and capabilities coupled with the right values and attitudes.Such skills and attitudes must be continually developed, strengthened, and reinforced, and each employee must be motivated and her efforts focused on the organization's goals and objectives. 24 The rise to prominence of knowledge workers as a vital source of competitive advantage is changing the balance of power in today's organization. Knowledge workers place professional development and personal enrichment (financial and otherwise) above company loyalty. Attracting, recruiting, and hiring the â€Å"best and the brightest,† Is a critical first step in the process of building intellectual capital.How to Lure Gene Y Workers? Commonly. Com, August 17: NP; Mantilla. 2007. How Going Green Draws Talent, Cut Costs. Wall Street Journal, November 13: BIO; and, O'Dell, A. M. 2007. Working for the Earth: Green Companies and Gree n Jobs Attract Employees. Www. Socializing . Com, 4. 1 environmental responsibility when it recruits on campuses. It showcases the company's new corporate headquarters, in Measuring, Ohio, that uses 28 percent to 39 percent less energy than a standard office building and is furnished with environmentally friendly materials.Says Nephew CEO Mark Sunny, â€Å"At the end of the day, we are competing with everyone else for the best talent, and this is a generation that is very concerned with the environment. † To meet the growing demand for students interested in working for green companies, Nonstarters, a unit of the giant employment firm Monster. Com, launched Greengrocers. It was the first online recruitment service that focuses on green employment. Econometrical and the Environmental Defense Fund, two environmental nonprofits, are adding their expertise in partnership with Nonstarters. Econometrical approached Nonstarters to create Greengrocers because there is an urgent need to reach and educate environmentally ‘agnostic' audiences, in this case college students, about the ways they can address climate change and other serious environmental problems,† claims Mark Cockroach, vice president and general manager at Nonstarters. Environmental sustainability To illustrate such interdependence, poor hiring impedes the effectiveness of development and retention processes. In a similar vein, ineffective retention efforts place additional burdens on hiring and development.Consider the following anecdote, provided by Jeffrey Prefer of the Stanford University Business School: Not long ago, I went to a large, fancy San Francisco law firm?where they treat their associates like dog do and where the turnover is very high. I asked the managing partner about the turnover rate. He said, â€Å"A few years ago, it was 25 percent, and now we're up to 30 percent. I asked him how the firm had responded to that trend. He said, â€Å"We increased our recruiting. â €  So I asked him, â€Å"What kind of doctor would you be if your patient was bleeding faster and faster, and your only response was to increase the speed of the transfusion? 29 Clearly, stepped-up recruiting is a poor substitute for weak retention. Although there are no simple, easy-to-apply answers, we can learn from what leading-edge firms are doing to attract, develop, and retain human capital in today's highly competitive marketplace. 30 Before moving on, Strategy Spotlight 4. 1 addresses the importance of firm's â€Å"green† or environmental sustainability strategy in attracting young talent. Deserted chic 118-155. Tend 124 Attracting Human Capital All we can do is bet on the people we pick. So my whole Job is picking the right people.Jack Welch, former chairman, General Electric Company 31 The first step in the process of building superior human capital is input control: attracting and selecting the right person. Human resource professionals often approach employee selection from a â€Å"lock and key' mentality?that is, fit a key (a Job candidate) into a lock (the Job). Such an approach involves a thorough analysis of the errors and the Job. Only then can the right decision be made as to how well the two will fit together. How can you fail, the theory goes, if you get a precise match of knowledge, ability, and skill profiles?Frequently, however, the precise matching approach places its emphasis on task-specific skills (e. G. , motor skills, specific information processing capabilities, and communication skills) and puts less emphasis on the broad general knowledge and experience, social skills, values, beliefs, and attitudes of employees. Many have questioned the precise matching approach. They argue that firms can identify top performers by focusing on key employee mind-sets, attitudes, social skills, and general orientations. If they get these elements right, the task-specific skills can be learned quickly. This does not imply, however, th at task-specific skills are unimportant; rather, it suggests that the requisite skill sets must be viewed as a necessary but not sufficient condition. ) This leads us to a popular phrase today and serves as the title of the next section. â€Å"Hire for Attitude, Train for Skill† Organizations are increasingly emphasizing general knowledge and experience, social skills, values, beliefs, and attitudes of employees. 32 Consider Southwest Airlines' hiring practices, which focus on employee values and attitudes. Given its strong team orientation, Southwest uses an â€Å"indirect† approach.For example, the interviewing team asks a group of employees to prepare a five- minute presentation about themselves. During the presentations, interviewers observe which candidates enthusiastically support their peers and which candidates focus on polishing their own presentations while the others are presenting. 33 The roomer are, of course, favored. Alan Cooper, president of Cooper Soft ware, Inc. , in Palo Alto, California, goes further. He cleverly uses technology to hone in on the problem- solving ability of his applicants and their attitudes before an interview even takes place.He has devised a â€Å"Bozo Filter,† an online test that can be applied to any industry. Before you spend time on whether Job candidates will work out satisfactorily, find out how their minds work. Cooper advised, â€Å"Hiring was a black see our test. It's a self-administering bozo filter. â€Å"34 How does it work? The online test asks questions designed to see how prospective employees approach provisioning tasks. For example, one key question asks software engineer applicants to design a table-creation software program for Microsoft Word. Candidates provide pencil sketches and a description of the new user interface.Another question used for design communicators asks them to develop a marketing strategy for a new touch- tone phone?directed at consumers in the year 1850. Cand idates e-mail their answers back to the company, and the answers are circulated around the firm to solicit feedback. Only candidates with the highest marks get interviews. Sound Recruiting Approaches and Networking Companies that take hiring seriously must also take recruiting seriously. The number of Jobs that successful knowledgeableness companies must fill is astonishing.Ironically, many companies still have no shortage of applicants. For example, Google, ranked fourth on Fortune's 2009 â€Å"100 Best Companies to Work For,† still attracts 777,000 applicants a year?even though hiring has slowed. 35 The challenge becomes having the right Job candidates, not the greatest number of them. Resources 125 Deserted chic 118-155. And 125 11/11/09 PM GE Medical Systems, which builds CT scanners and magnetic resonance imaging (MR.) systems, relies extensively on networking. They have found that current employees are the best source for new ones.Recently, Steven Potshot, head of staff ing and leadership development, made a few simple changes to double the number of referrals. First, he simplified the process?no complex forms, no bureaucracy, and so on. Second, he increased incentives. Everyone referring a qualified candidate received a gift certificate from Sears. For referrals who were hired, the â€Å"bounty' increases to $2,000. Although this may sound like a lot of money, it is â€Å"peanuts† compared to the $1 5,000 to $20,000 fees that GE typically pays to headhunters for each person hired. 6 Also, when someone refers a former colleague or friend for a Job, his or her credibility is on the line. Thus, employees will be careful in recommending people for employment unless they are reasonably confident that these people are good candidates. This provides a good â€Å"screen† for the firm in deciding whom to hire. Hiring the right people makes things a lot easier: fewer rules and regulations, less need for monitoring and hierarchy, and greater i nitialization f organizational norms and objectives. Consider some of the approaches that retire, people in this demographic group are becoming more and more important in today's workforce.We also provide some â€Å"tips† on how to get hired. We address these issues in Exhibit 4. 3. Developing Human Capital It is not enough to hire top-level talent and expect that the skills and capabilities of those employees remain current throughout the duration of their employment. Rather, training and development must take place at all levels of the organization. 37 For example, Selection assembles printed circuit boards and other components for TTS Silicon Valley clients. 38 Its employees receive an average of 95 hours of company- provided training each year.Chairman Winston Chem. observed, â€Å"Technology changes so fast that we estimate 20 percent of an engineer's knowledge becomes obsolete each year. Training is an obligation we owe to our employees. If you want high growth and hig h quality, then training is a big part of the equation. † Although the financial returns on training may be hard to calculate, most experts believe it is essential. One company that has calculated the benefit from training is Motorola. Every dollar spent on training returns $30 in productivity gains over the following three years.In addition to training and developing human capital, firms must encourage widespread involvement, monitor and track employee development, and evaluate human capital. 39 Encouraging Widespread Involvement Developing human capital requires the active involvement of leaders at all levels. It won't be successful if it is viewed only as the responsibility of the human resources department. Each year at General Electric, 200 facilitators, 30 officers, 30 human resource executives, and many young managers actively participate in Gee's orientation program at Correlation, its training center outside New York City.

The system's interaction shown in Figure 7. 26 begins with the Registrations object passing the registration information to the section object.This section object needs to check if the student has the prerequisites for the course. If the Boolean returned is True then the message Add(student) is sent to students object. Note: another sequence diagram would represent Boolean = False. 8. Explain â€Å"Adding a course† from section 7. 3. 4. 1 using Normal's 7 Stage Model. 1 Form a goal -? add Engle 201 1 – The user (student) forms the goal â€Å"l need to add Engle 2011 to my schedule†. 2 Form an intention – find Engle 201 1 The user (student) forms the intention on the screen shown in 7. 26 to find Engle 201 1 in the drop box. Specify the action – mouse can show courses in the drop box – The user will decide to use the mouse to click and hold open the drop box and move the mouse down until he/she sees the Engle 2011 course. Execute the action – The user moves the mouse to the arrow in the drop box and clicks when he/she is on the arrow of the drop box. 5 Perceive the system state (feedback) – he/she sees the drop box open with multiple courses in a list. 6 Interpret the feedback – he/she sees the Engle 201 1 7 Evaluate – because the user sees the course they evaluate â€Å"Success† to their intention.Note: They would continue with the next intention to click â€Å"Add Course†. 9. List the four components of the GYMS model for user interfaces. The 4 factors of GYMS model are : Goals, Operators, Methods, and Selection Rules 10. Explain how the Model-View-controller architectural style is done using HTML-Script-SQL. The Model-View-Controller (MFC) architectural style is done with HTML as t he View of the system and SQL as a database. The database has the model of the system. PH is the script used as the controller for the system. Chapter 8: 1 .Question: What are the two general characteristics of a design that naturally carry over from requirements? Answer: The design is an evolution from requirements. So the two general characteristics of a) consistency and b) completeness of requirements usually carry over to the design. 2. Question: What is Menace's climatic complexity number a) attempting to measure, and b) what is the climatic complexity number of a program A that contains 3 binary predicates (or branches)? Answer: a) Menace's climatic complexity number measures the control flow complexity of software. ) Using the simple formula of (#if binary branches + 1), the climatic number of program A is (3+1 ) or 4. 3. Question: What is a program slice? Answer: A program slice is the set of statements that can affect the value of some specified variable of interest in the program. 4. Question: What are glue tokens and super glue tokens, and which type nutrients more to cohesion? Answer: Glue tokens are data tokens that lie in more than one data-slice, and super glue tokens are data tokens that lie in every data-slice. The super glue tokens contribute more to cohesion because they lie in every data slice. 5. Question: What is software cohesion?Answer: Cohesion is a characteristic that describes the degree of relatedness within the software. 6. Question: What are the levels of cohesion? Answer: There are 7 levels of cohesion listed in the order of worst to best: coincidental, logical, temporal, procedural, communicational, sequential, and national. 7. Question: What is software coupling? Answer: Coupling is a characteristic that describes the degree of interdependence or interaction among the parts within the software. 8. Question: What are the levels of coupling? Answer: There are 5 levels of coupling listed in the order of worst to best: content, com mon, control, stamp, and data. . Question: What are the six design measurements of C-K metrics in 00? Answer: They are a) weighted number of methods per class, b) depth of inheritance tree of the class, c) number of children of a class, d) coupling between objects, e) number of espouses to a class message, and f) lack of cohesion among methods in a class 10. Question: In contrast to general design, what is user interface design interested in? Answer: The general software design is concerned about the software components, their characteristics and their interactions.User interface design is focused on the interaction between the software and its human users; thus both software and human attributes are of concern in user interface design. 1 1 . Question: List four out of the eight rules of user interface design identified by Seminarian and Pleasant. Answer: There are actually 8: a) consistency, b) roved short cuts, c) informative feedback, d) closure in dialogues, e) simple error hand ling and prevention, f) permit â€Å"re-do†, g) support locus of control, h) reduce the amount of short-term memory needs. Any four of the eight would be fine. 12.Question: What are the general cohesion and coupling goals when designing software? Answer: We strive for lesser or looser coupling of software, and we design for stringer or tighter cohesion. 13. Question: What is the Law of Demeter attempting to achieve? Answer: Law of Demeter is a set of guiding rules that limits the span of control of an object y restricting the messaging structure among methods of a class. Through these restrictions it is conjectured that we can reduce coupling and enhance cohesion. 14. Question: What is fan-in and fan-out, and what attribute do they measure?Answer: Fan-in is a measure of number of information flow into a module or component. Fan-out is the number of information flow out of a module. An example of fan-in for module-x would be the number of modules that call module-x and for fan -out of module-x would be the number of modules that are called by module-x. Thus fan-in and fan-out measure the coupling attribute among modules. Chapter 9: 1. Question: is the act of transforming the detailed design into a valid program in some programming language. Answer: Implementation. 2. Question: List 3 desirable characteristics of a good implementation.Answer: Readability; maintainability; performance; traceability; correctness; completeness. 3. Question: True or False? : The most important issues for maintaining a good coding style are: to be consistent and to try to highlight the meaning of your code. Answer: True. 4. Question: You should choose longer names for local variables or entities, but can use shorter ones for global variables or entities. Answer: False. 5. Question: List 3 of the types of code comments described in the book. Answer: Repeat of the code; explanation of the code; marker in the code; summary of the code; description of the code intent; external refe rences.
