Critical context, Essay Example | Topics and Well Written Essays - 2500 words

Critical context, - Essay Example ong had never taken place at all based on an assessment of economic and other losses and injuries that have been caused to the Plaintiff.3 Tort offers an option for the victims to shift at least some of the costs for the damages that they have to bear on to others who may be partly responsible for the fate of the victim. In order to establish a cause of action under tort, three aspects must be established: Liability under tort is generally determined along the lines of (a) strict liability or (b) no fault liability. Under the tort of strict liability, a defendant will be obliged to pay damages for a breach of duty of care and the Court will not question whether or not the defendant has acted in a justifiable manner. On the other hand in a case of no fault liability, it is possible that a victim may not receive damages for the harm caused if there has been a good justifiable reason for the wrong that has been perpetrated on the victim. Applying this to the case of the Marsh Down school children, the children and their parents could have had good cause to file a suit for tort on the basis of personal injuries at the disco, if they had suffered them. Firstly, the nature of the harm would have been serious enough to merit a cause of action, secondly, the cause of such injuries would have been the wrongful action of the school in giving publicity to the August camp in the local paper, especially in view of ethnic diversities among the school children. The School could have therefore been a party to the suit, with the supervising teachers – Clyde West, James, Dot and Duff being cited as respondents. It is the school that is most likely to be held liable, because the teachers are employed by the school and injuries that have occured to students at the dicso are the result of the failure of the teachers to protect them. As a result, vicarious liability will be imputed to the school, since an employer is expected t o be responsible for the negative consequences

Founding Brothers Essay Example for Free

Founding Brothers Essay The novel, Founding Brothers, written by Joseph Ellis is a thought provoking novel on the intertwined lives of George Washington, Thomas Jefferson, James Madison, John Adams, Alexander Hamilton, Aaron Burr and Ben Franklin. Ellis calls the 1790’s the most decisive decade in our country. The author exemplifies three major points in our nation’s history: George Washington and his prominent legacy; the collaborative yet antagonistic relationship between Thomas Jefferson and John Adams; and the many problems of the young union during its revolutionary era. George Washington was a monumental character and played a vital role in the molding of our country. Although, his reputation was nearly impeccable, he was great in stature, standing at six foot four. The farewell address was a key element to Washington’s legacy. In this he displayed how grateful he was to have such a remarkable opportunity to serve his country, although this only was the beginning part of his speech. Secondly he decided to stress the importance of the union. But it started in 1776 when Washington was being described as â€Å"Father of our Country† prematurely. Even Ben Franklin acknowledged Washington’s supremacy. In the 1790’s Washington was well known, he was the presiding officer at the Constitutional Convention and the chief executive of the federal government. â€Å"Washington was the core of gravity that prevented the American Revolution from flying off into random orbits, the stable center around which the revolutionary energies formed† (Ellis 121). He impacted the government tremendously with his way of thinking and his attitude toward the need for national unity. He talked about independence from foreign nations; he devoted several paragraphs to this in his in his address. Washington always made the well- being of the country first. For example, when Continental Congress wanted help the French with an invasion of Canada, Washington opposed. He feared that that putting the France in possession of that capital that they would become greedy, and doubted that they would withdraw once they were ensconced in Canada. I think that he may have felt that also, America was young and still growing as a country. He was criticized for this decision. In closing on Washington’s legacy, I feel that there were many reasons why he retired. In short, he was just getting old and probably couldn’t take the political pressure. He was also going through a physical decline. Washington intended for his farewell address to be advice to his countrymen. He wanted them to sustain without, and without a king. Adams and Jefferson were indeed friends but had different agendas on how the country should be run. Their relationship was unique; they were great friends but even better competitors. The presidency drove them apart. Adams was a federalist, and Jefferson was a democratic republican so to speak. Through the Continental congress and diplomatic missions they became close friends. As they worked more together Adams developed more respect Jefferson, although he was less effusive. The low point of their relationship was definitely after the election in 1800. After this their relationship became more antagonistic. As politicians and colleagues they went through many phases. After the election they did not speak for a long 12 years. Adams felt that Jefferson had betrayed their friendship. After the death of Jefferson daughter, Abigail Adams began to exchange letters of condolences. Jefferson confused it as an invitation to reconcile with Adams family. The two disputed briefly, John didn’t find out until several months later. Finally in January of 1812, Adams sent a letter from Quincy to Monticello. â€Å"Why then, did Adams take the fateful step, which led to a fourteen year exchange of 158 letters, a correspondence that is generally regarded as the intellectual capstone to the revolutionary generation and the most impressive correspondence between prominent states in all of American history† (Ellis 223)? For the last 15 years of their lives they contacted each other through letters and rebuilt their friendship. On the 50th Anniversary of the signing of the Declaration of the Independence, both Thomas Jefferson and John Adams died within hours of each other. They will never be forgotten for the inevitable and timely contributions to our young country. In the introduction Ellis describes the American Revolution perfectly with the statement â€Å"No event in American history which was so improbable at the time has seemed as inevitable in retrospect as the American Revolution†. America’s victory seemed beyond improbable seeing as how England had the greatest army of the Revolutionary era. The young colonists chose to seek out alliances with the French, Dutch, and Spanish due to their lack of monetary resources, experience or even the pure man power. British beforehand, even tried attacking the colonists politically which had their in leading to an inevitable rebellion. They initiated taxes, and other events such as the Boston Massacre took place that ignited the young colonists to take stand against Great Britain. Though faith, inspiration and prosperity the Americans shocked the world, defeated the odds and took the victory in 1783, securing their new independent world. This victory inspired countries worldwide to rebel against the tyrannical empires that were controlling them. This victory is evident in today’s society as America thrives as country that influences others and still is, independent. Founding Brothers truly exposes a much more personal point of view of our founding fathers and their irrefutable destiny. Joseph Ellis targets critical elements of their and what they thought was best for the young country of America. They molded something bigger than themselves during this revolutionary era. The author really brings to life the intricate detail of Washington’s legacy and the partnership between two great leaders Thomas Jefferson and John Adams. Joseph Ellis’ statement was more than valid; it justifies American in a few short words.

Put a Girl in it Essay -- Sociology, Human Companionship

Put a Girl in it Human companionship is one of the most basic needs of humans that can be seen in the Creation story. It is tricky for any human to find the perfect companion, especially if one is one of a kind. In Mary Shelly’s Frankenstein two characters exemplify this need Dr. Victor Frankenstein and The Creature. They are in search of the same thing companionship, and they go to great lengths to try to achieve it from the traditional to scientific discoveries. The classic theme of perversion of family is a major component in Frankenstein. Dr. Frankenstein comes from a good family and in his adult life he longing for a loving companion is mainly found in the pursuit of the Creature and Elizabeth. The development for the need for the Creature starts when he falls in love with knowledge and is furthered when he leaves to study. In his childhood he finds â€Å"Natural philosophy is the genius that has regulated my fate; I desire, therefore, in this narration, to state those facts which led to my predilection for that science† (Shelley 36). This passion develops into his obsession in his adult life when he gains more accesses to scientific knowledge and new technology. Then it climaxes with start of the creation of the Creature because his accesses to bodies and tools. Victor sees his progression, â€Å"I read with ardour those works, so full of genius and discrimination†¦ it easily conceived that my progress was rapid† (48 ). His description of the creation makes it seem like he is mothering a child into birth. He distorts the sanctity of childbirth by creating a human in a lab. This also makes him the mother and father of the Creature. He realizes the immense power he holds, â€Å"When I found so astonishing a power placed within my han... ...led â€Å"You must create a female for me with whom can live in the interchange of those sympathies necessary for being† (145). Creature seems to be devout of all humanity except the meager scrapes of which it was made, but it still appears to have the deep emotional needs of all humans. Having to fight off the world he seems callus. The need for a female is so overpowering, it forsakes everything to just have a companion to love. The Creature is seen as a human. It really shares all the properties that humans have but it is ostracized because of his appearance. The basic need of compassion and a companion is shared by all humans. Victor Frankenstein and his child Creature both long for the same thing, a companion to love. They both conflict with the others pursuit of companionship.

Milgram’s Destructive Obedience Essays -- Psychology

Stanley Milgram was a social psychologist best known for an experiment he did regarding destructive obedience (Hockenbury & Hockenbury, 2011). According to McLeod, Milgram had originally set out to prove that Germans were somehow more obedient than Americans. This was a short while after WWII had finished and the horrors committed by the Nazis under Hitler’s authority had been learned. His experimental results were contradictory to the results predicted by fellow psychiatrists, college students and some adults of various occupations. They had predicted that very few people would obey an order that would harm another person; however, the actual results proved quite the opposite. Instead of proving that German’s were more obedient, Milgram opened the door to the possibility that anyone is capable of carrying out orders that would harm another person (2007). Douglas Navarick expanded on the experiment’s results and derived a three-stage model for defiance and withdrawal (2012). After comparing the three sources on the previously mentioned topic, it is my belief that the peer reviewed journal (Navarick, 2012) is the most credible. Its credibility is largely accredited to the established requirements of publication in the journal it is found in. Hockenbury and Hockenbury summarized Milgram’s experiments as simply as they could. The test subject was led to believe that the second participant was as uniformed as they were and that their roles in the experiment were chosen at random. They were told that the experiment was about learning and memory and the effect punishment has on them. The test subject was given the role of â€Å"teacher† and the other participant given the role of â€Å"learner† seemingly at random. The second partici... ... it means avoiding personal discomfort. A source is considered credible if it is accepted by general consensus of the experts of the field it concerns. It should also show the scientific facts that support it. A standalone source that does not show any form of reference to other psychologists that agree with or support his/her theory would not be considered as credible.

Critical Thinking and Ethics Essay

In a discussion of ethics, critical thinking may not be the first term that comes to mind, unless opposing. However in some ways, critical thinking can the foundation, from which an ethical decision is made. This paper will explain the relationship between critical thinking and ethics, how the principles and rules of critical thinking are applicable to ethical reasoning, and if ethical decisions would be necessary if everyone followed the rules of logic. Is Critical Thinking Applicable to Ethical Reasoning? Ethical reasoning is based on the principles of what is considered right and wrong. Critical thinking on the other hand, warrants more of a thought process, causing one to analyze the situation from all aspects before reaching a conclusion. â€Å"By taking the path of a critical thinker, a person develops a mental process of evaluation which helps to determine their ethical standards† (Mnmelillo, 2010, Professional Growth, para. 1). Logic versus Ethical Reasoning The purpose of logic is to find that which is true. Logical thinking processes are often times used in ethics to answer important moral questions. However logic does not guarantee a morally correct outcome. For example, the legalization of marijuana is constantly under debate. Using the rules of logic, one would be able to see both the pros and cons of this argument. Although drug use is considered unethical by US government standards, even for medicinal use, the state of California, has legalized medicinal marijuana. In this particular case or should I say state, the rules of logic did not produce a morally correct result. Conclusion Ethical reasoning and critical thinking are derived from different  processes, although there are circumstances in which one is necessary to reach a decision regarding the other. As with critical thinking, there are no hard rules determining the use of ethics, considering what may be unethical in some cultures, for example, may prove to be ethical in another. Ultimately the use of ethics versus critical thinking or logic is determined by the situation at hand. Reference: Mnmelillo, N. (2010). What is the relationship between critical thinking and ethics?

Free Essays on Deaf Culture

Deaf Culture: Is it all Peaceful? Deafness is not a disability but a different way of being. â€Å"So the members of the American deaf community are not characteristically isolated, or uncommunicative, or unintelligent or childlike, or needy, or any of these things we imagine them to be,† stated Harlan Lane (269). The deaf produce their own culture and way of living. Knowing that, what is a culture, what are factors in their culture, and why is there negativity associated with the deaf community producing their own culture? Culture is what individuals learn in life. Cultures are taught. Individuals learn their culture from people within their society. They learn language, acceptable behavior, beliefs, customs, and values to help them throughout life. Cultures can also be viewed as a standard of living and be used as a sense of belonging. There are many cultures in this world. They range from cultures of a particular country to cultures of a certain group. There are even cultures within a culture. The deaf community for example has more than one culture. The main culture they learn is the culture they are raised in, basically, what their countries’ cultures are, but they are also part of their own culture. Deaf individuals have their own language, needs, and customs along with the mainstream culture they live in. In the deaf community, they have their own opportunities for their group of people. They have schools, social activities, jobs, and forms of communication to say the least. Deaf grade schools and colleges are all over the country. One of the better-known colleges is Gallaudet University. According to Oliver Sacks, â€Å"Gallaudet is the only liberal arts college for the deaf in the world and is, moreover, the core of the world’s deaf community† as of 1988 (236).

Introduction to the Human Genome Project

Introduction to the Human Genome Project The set of nucleic acid sequences or genes that form the DNA of an organism is its genome. Essentially, a genome is a molecular blueprint for constructing an organism. The human genome is the genetic code in the DNA of the 23 chromosome pairs of Homo sapiens, plus the DNA found within human mitochondria. Egg and sperm cells contain 23 chromosomes (haploid genome) consisting of around three billion DNA base pairs. Somatic cells (e.g., brain, liver, heart) have 23 chromosome pairs (diploid genome) and around six billion base pairs. About 0.1 percent of the base pairs differ from one person to the next. The human genome is about 96 percent similar to that of a chimpanzee, the species that is the nearest genetic relative. The international scientific research community sought to construct a map of the sequence of the nucleotide base pairs that make up human DNA. The United States government started planning the Human Genome Project or HGP in 1984 with a goal to sequence the three billion nucleotides of the haploid genome. A small number of anonymous volunteers  supplied the DNA for the project, so the completed human genome was a mosaic of human DNA and not the genetic sequence of any one person. Human Genome Project History and Timeline While the planning stage started into 1984, the HGP didnt officially launch until 1990. At the time, scientists estimated it would take 15 years to complete the map, but advances in technology led to completion in April of 2003 rather than in 2005. The U.S. Department of Energy (DOE) and U.S. National Institutes of Health (NIH) provided most of the $3 billion in public funding ($2.7 billion total, due to early completion). Geneticists from all over the world were invited to participate in the Project. In addition to the United States, the international consortium included institutes and universities from the United Kingdom, France, Australia, China, and Germany. Scientists from many other countries also participated. How Gene Sequencing Works To make a map of the human genome, scientists needed to determine the order of the base pair on the DNA of all 23 chromosomes (really, 24, if you consider the sex chromosomes X and Y are different). Each chromosome contained from 50 million to 300 million base pairs, but because the base pairs on a DNA double helix are complementary (i.e., adenine pairs with thymine and guanine pairs with cytosine), knowing the composition of one strand of the DNA helix automatically provided information about the complementary strand. In other words, the nature of the molecule simplified the task. While multiple methods were used to determine the code, the main technique employed BAC. BAC stands for bacterial artificial chromosome. To use BAC, human DNA was broken into fragments between 150,000 and 200,000 base pairs in length. The fragments were inserted into bacterial DNA so that when the bacteria reproduced, the human DNA also replicated. This cloning process provided enough DNA to make samples for sequencing. To cover the 3 billion base pairs of the human genome, about 20,000 different BAC clones were made. The BAC clones made what is called a BAC library that contained all the genetic information for a human, but it was like a library in chaos, with no way to tell the order of the books. To fix this, each BAC clone was mapped back to human DNA to find its position in relation to other clones. Next, the BAC clones were cut into smaller fragments about 20,000 base pairs in length for sequencing. These subclones were loaded into a machine called a sequencer. The sequencer prepared 500 to 800 base pairs, which a computer assembled into the correct order to match the BAC clone. As the base pairs were determined, they were made available to the public  online and free to access. Eventually all the pieces of the puzzle were complete and arranged to form a complete genome. Goals of the Human Genome Project The primary goal of the Human Genome Project was to sequence the 3 billion base pairs that make up human DNA. From the sequence, the 20,000 to 25,000 estimated human genes could be identified. However, the genomes of other scientifically significant species were also sequenced as part of the Project, including the genomes of the fruit fly, mouse, yeast, and roundworm. The Project developed new tools and technology for genetic manipulation and sequencing. Public access to the genome assured the entire planet could access the information to spur new discoveries. Why the Human Genome Project Was Important The Human Genome Project formed the first blueprint for a person and  remains the largest collaborative biology project that humanity ever completed. Because the Project sequenced genomes of multiple organisms, scientist could compare them to uncover the functions of genes and to identify which genes are necessary for life. Scientists took the information and techniques from the Project and used them to identify disease genes, devise tests for genetic diseases, and repair damaged genes to prevent problems before they occur. The information is used to predict how a patient will respond to a treatment based on a genetic profile. While the first map took years to complete, advances have led to faster sequencing, allowing scientists to study genetic variation in populations and more quickly determine what specific genes do. The Project also included the development of an Ethical, Legal, and Social Implications (ELSI) program. ELSI became the largest bioethics program in the world and serves as a model for programs that deal with new technologies.

About the United States Congress - Overview

About the United States Congress - Overview The Congress of the United States was created by Article I, section 1, of the Constitution, adopted by the Constitutional Convention on September 17, 1787, providing that All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives. The first Congress under the Constitution met on March 4, 1789, in the Federal Hall in New York City. The membership then consisted of 20 Senators and 59 Representatives. New York ratified the Constitution on July 26, 1788, but did not elect its Senators until July 15 and 16, 1789. North Carolina did not ratify the Constitution until November 21, 1789; Rhode Island ratified it on May 29, 1790. The Senate is composed of 100 Members, 2 from each State, who are elected to serve for a term of 6 years. Senators were originally chosen by the State legislatures. This procedure was changed by the 17th Amendment to the Constitution, adopted in 1913, which made the election of Senators a function of the people. There are three classes of Senators, and a new class is elected every 2 years. The House of Representatives comprises 435 Representatives. The number representing each State is determined by population, but every state is entitled to at least one Representative. Members are elected by the people for 2-year terms, all terms running for the same period. Both the Senators and the Representatives must be residents of the State from which they are chosen. In addition, a Senator must be at least 30 years of age and must have been a citizen of the United States for at least 9 years; a Representative must be at least 25 years of age and must have been a citizen for at least 7 years. [Â  How Much Do Members of Congress Really Make? ] A Resident Commissioner from Puerto Rico (elected for a 4-year term) and Delegates from American Samoa, the District of Columbia, Guam, and the Virgin Islands complete the composition of the Congress of the United States. Delegates are elected for a term of 2 years. The Resident Commissioner and Delegates may take part in the floor discussions but have no vote in the full House or in the Committee of the Whole House on the State of the Union. They do, however, vote in the committees to which they are assigned. Officers of CongressThe Vice President of the United States is the Presiding Officer of the Senate; in his absence the duties are taken over by a President pro tempore, elected by that body, or someone designated by him. The Presiding Officer of the House of Representatives, the Speaker of the House, is elected by the House; he may designate any Member of the House to act in his absence. The positions of Senate majority and minority leader have been in existence only since the early years of the 20th century. Leaders are elected at the beginning of each new Congress by a majority vote of the Senators in their political party. In cooperation with their party organizations, leaders are responsible for the design and achievement of a legislative program. This involves managing the flow of legislation, expediting noncontroversial measures, and keeping Members informed regarding proposed action on pending business. Each leader serves as an ex officio member of his partys policymaking and organizational bodies and is aided by an assistant floor leader (whip) and a party secretary. [Â  How to Write Effective Letters to Congress ] The House leadership is structured essentially the same as the Senate, with the Members in the political parties responsible for the election of their respective leader and whips. The Secretary of the Senate, elected by vote of the Senate, performs the duties of the Presiding Officer of the Senate in the absence of the Vice President and pending the election of a President pro tempore. The Secretary is the custodian of the seal of the Senate, draws requisitions on the Secretary of the Treasury for moneys appropriated for the compensation of Senators, officers, and employees, and for the contingent expenses of the Senate, and is empowered to administer oaths to any officer of the Senate and to any witness produced before it. The Secretarys executive duties include certification of extracts from the Journal of the Senate; the attestation of bills and joint, concurrent, and Senate resolutions; in impeachment trials, issuance, under the authority of the Presiding Officer, of all orders, mandates, writs, and precepts authorized by the Senate; and certification to the President of the United States of the advice and consent of the Senate to ratification of treaties and the names of persons confirmed or rejected upon the nomination of the President. The Sergeant at Arms of the Senate is elected by and serves as the Executive Officer of that body. He directs and supervises the various departments and facilities under his jurisdiction. He is also the Law Enforcement and Protocol Officer. As Law Enforcement Officer, he has statutory power to make arrests; to locate absentee Senators for a quorum; to enforce Senate rules and regulations as they pertain to the Senate Chamber, the Senate wing of the Capitol, and the Senate Office Buildings. He serves as a member of the Capitol Police Board and as its chairman each odd year; and, subject to the Presiding Officer, maintains order in the Senate Chamber. As Protocol Officer, he is responsible for many aspects of ceremonial functions, including the inauguration of the President of the United States; arranging funerals of Senators who die in office; escorting the President when he addresses a Joint Session of Congress or attends any function in the Senate; and escorting heads of state when they visit the Senate. The elected officers of the House of Representatives include the Clerk, the Sergeant at Arms, the Chief Administrative Officer, and the Chaplain. The Clerk is custodian of the seal of the House and administers the primary legislative activities of the House. These duties include: accepting the credentials of the Members-elect and calling the Members to order at the commencement of the first session of each Congress; keeping the Journal; taking all votes and certifying the passage of bills; and processing all legislation. Through various departments, the Clerk is also responsible for floor and committee reporting services; legislative information and reference services; the administration of House reports pursuant to House rules and certain legislation including the Ethics in Government Act and the Lobbying Disclosure Act of 1995; the distribution of House documents; and administration of the House Page Program. The Clerk is also charged with supervision of the offices vacated by Members due to death, resignation, or expulsion. Clerk of the HouseThe Sergeant at Arms maintains the order of the House under the direction of the Speaker and is the keeper of the Mace. As a member of the U.S. Capitol Police Board, the Sergeant at Arms is the chief law enforcement officer for the House and serves as Board Chairman each even year. The ceremonial and protocol duties parallel those of the Senate Sergeant at Arms and include arranging the inauguration of the President of the United States, Joint Sessions of Congress, visits to the House of heads of state, and funerals of Members of Congress. The Sergeant at Arms enforces the rules relating to the privileges of the Hall of the House, including admission to the galleries, oversees garage and parking security of the House, and distributes all House staff identification cards. Congressional CommitteesThe work of preparing and considering legislation is done largely by committees of both Houses of Congress. There are 16 standing committees in the Senate and 19 in the House of Representatives. The standing committees of the Senate and the House of Representatives can be viewed from the links below. In addition, there are select committees in each House (one in the House of Representatives), and various congressional commissions and joint committees composed of Members of both Houses. Each House may also appoint special investigating committees. The membership of the standing committees of each House is chosen by a vote of the entire body; members of other committees are appointed under the provisions of the measure establishing them. Each bill and resolution is usually referred to the appropriate committee, which may report a bill out in its original form, favorably or unfavorably, recommend amendments, report original measures, or allow the proposed legisla tion to die in committee without action.

Customer behaviour towards online shopping Essay

Customer behaviour towards online shopping - Essay Example Introduction 1.1 Introduction The development of the Internet has not only provided a technological tool but also an essential tool for commercial dealings. In recent years, business people and their customers have increasingly used the Internet for a variety of purposes. Businesses use the Internet and other online functions such as electronic mail as a means of advertising their products and popularizing their brands to their prospective customers. The Internet has also made it possible for consumers to research the brands and products they intend to buy and then purchase their desired products online. Businesses that have embraced the use of the Internet have seen their organizations grow at the same time that they have seen their costs of advertising shrink (Evans, 2009). Such firms have also witnessed an increase in overall sales levels due to increased online shopping. Industry related sources such as the Interactive Media in Retail Group (IMRG, 2012) anticipate that Internet s ales just in the UK will be approximately seventy seven billion pounds or more by the end of year 2012. The Internet can have profound effects on the way one conducts business. It has become a vital tool and avenue for carrying out trade and aids to trade, i.e. commerce. As a tool, it equips buyers and sellers with adequate information on products and services. As an avenue, it overcomes the limitation brought about by geographical distance, time zone, and the need for a physical office. Great Britain has experienced the fastest growth in terms of electronic shopping in the entire Europe, having estimated sales of sixty eight billion pounds in the year 2011 representing an increase of 1.6% (Wood, 2012).... This paper considers general Internet usage in the context of marketing, provide an overview of online shopping, and discuss the profitability of online shopping over the past few years, before looking at Tesco and Asda specifically. Finally, since the factors that affect consumer confidence towards online shopping are diverse, it is important to study some of the factors within e-marketing frame such as product, price, promotion, distribution and customer service. Technological factors and demographics as well as social factors are also important and are considered as the macro environment of marketing. The World Wide Web has dramatically increased the general use of the Internet. In 1993, the World Wide Web was developed to be a commercial tool by the British scientist Tim Berners-Lee. Instead of using the Internet's â€Å"World Wide Webâ€Å" as a technological tool, the Internet quickly became an effective commercial outlet for vendors and customers. By late 2000, the Internet already had more than 450 million online users thanks to the convenience of the World Wide Web. According to estimates by Nua, there were already more than 30 million hosted websites as reported by the various server organizations by that time (Web update, www.nua.ie/surveys). This proves that the Internet environment is very effective and important for business (www.emarketing.com). E-business success through the Internet is also evidence of increasingly new customers to online shopping for company products and services.

Capital emerged as the pivotal factor of production. This led to a greater polarization of opinion on both sides that are the labor and the capitalists, thereby both sections getting more organized and politicized. One negative thing about Industrial Revolution was that it envisaged earth as an external resource to serve as a fodder for the industrial engine of growth. In the long run it not only resulted in an irreversible depletion of natural resources and the commensurate pollution, but led to the contemporary challenges like global warming. There is no denying the fact that the map set by Industrial Revolution is not absolutely relevant in the current times marked by the emergence of new priorities like sustainable development and corporate social

Medical Group Analysis Essay Example | Topics and Well Written Essays - 1750 words

Medical Group Analysis - Essay Example Different points of view of each group contribute to establish a level on which each group functions or does not function, and to see how interaction in the group and interaction of that group with the society has an influence in the efficiency of medical care. The importance of each group can be observed through close analysis of its interaction with society and itself. Therefore, two important aspects can be differentiated. The micro-level interaction in the groups explains the working conditions, while at a macro level it explains their purpose in society and the potentials and problems of globalization. Although modern nursing was created a little more than a hundred years ago, mostly by the enormous contribution of Florence Nightingale during the Crimean War, the foundations of nursing were laid many centuries before the publication of the first nursing guidelines. Nursing and its formation as a science is closely related to and must be placed within a sociological perspective; the desire to help the sick and injured is a continuing sociological phenomena, dating back to the formation of the first civilizations. A fine example is the effort of nuns and other clergy during the middle ages, which essentially performed the duties of modern nurses. Society and science may have changed over the ages, but the necessity for a specific medical group that cares, both for the physical and psychological well-being, of the sick is always present. The 1.3 million registered nurses working in hospitals in the United States, and the ever growing demand is a natural results of the necessity of nu rses (Steinbrook, 2002). Much research is done into the micro-level interaction of nurses and nursing groups in hospitals in order to determine the effectives of the latter. Most of the research was performed through participation observation, and according to one research, it was determined that the hours of nursing care provided by registered nurses is proportional with better care for hospitalized patients (Steinbrook, 2002). Also, the larger number of registered-nurse-hours per day or licensed-nurse-hours per day is associated with a lower rate of failure to rescue critical patients. Studies have also reported a correlation between higher levels of staffing by nurses and lower mortality and lower rates of other outcomes. According to another research, however, conducted amongst surgical patients, no evidence was found of an association between in-hospital mortality and the proportion of registered-nurse-hours, leading to the conclusion that mortality is not connected with good care of nurses but with oth er health care group. If we observe two different hospitals, where we can determine the symbolic interaction between different nursing groups, we are supposed to consider other unmeasured factors with higher levels of staffing by registered nurses or other unmeasured characteristics of the hospitals' nursing work force. The level of staffing by nurses is an incomplete measure of the quality of nursing care in hospitals. Other factors, such as effective communication between nurses and physicians and a positive work environment, have been found to influence patients' outcomes. The outcomes for which we found

The Risky Undertaking of a Business Opportunity by an Entrepreneur Essay

The Risky Undertaking of a Business Opportunity by an Entrepreneur - Essay Example All organizations have an external environment, which plays a key role in determining the success or failure of the organization (Ebert and Griffin ). The external environment of the organization consists of all the outside forces and factors that may affect the organization either positively or negatively. It is therefore very important for any organization manager to have a clear understanding of this environment. There are six external environments and they can affect an organization either directly or indirectly. The six environments include the domestic environment; this comprises of the environment in which the organization carries out its business and generates income. The second environment is the global environment; this is composed of the international forces and factors that affect the operation of the business either direct or indirect (Ebert and Griffin ). The third environment is technological; this environment is made up of the factors and ways in which the organizatio n generates value for its constituents. Four environments are made up of Political-legal environment; this is comprised of the link between the business and the government. A thorough knowledge into this environment is essential for any manager. The fifth environment is socio-cultural and it deals with the society in which the organization operates. It reflects on the demographic characteristics and the customer's values of society. Lastly, there is the economic environment; this section reflects on the relevant conditions that are linked to the economic system in which the firm operates.

Accrual Method Essay Example for Free

Accrual Method Essay The accrual method of accounting and the cash basis of accounting are different in the way that they record transactions. With cash basis accounting, the agency records money to its book once it is received or when it leaves their system. The accrual method, though, records a transaction when it happens, even if they do not receive money for it yet. Accrual accounting is a more accurate portrait of the nonprofit organization’s finances. If they supply a service they immediately record the cost of that service. This point of view is important because it is more accurate than the cash basis form of accounting, which only documents income when cash comes into the organization. The statement of cash flow is of fundamental importance to an organization’s financial management. This statement gives the organization a breakdown of every transaction that comes in or out. This is totaled up over a particular time period. If there are any differences in the organizational transactions, the statement of cash flow makes this clear. The financial stability of an organization rests on what money they make or spend every day. The organization might go bankrupt if they do not track how their money is spent. These accounting practices offer solid documentation of where money goes.

Geography and Culture of the uk

Most of its colonies became independent, and many sectors of the British economy became nationalized. Not until the 1960 did Britain fully recover from World War II. In 1979 Margret Thatcher became Britain’s first women prime minister. She became commonly known as the â€Å"Iron Lady† for her politics and leadership style. In the 1980 she began privatization of state-owned companies and reducing the power of trade unions. Culture According to the Hofstede Centre website the current rankings for the United Kingdom is as follows, Power distance 35, Individualism 89, Masculinity 66, Uncertainty avoidance 35, and Long Term Orientation 25. At a rank of 35 the United Kingdom ranks low in the power distance, reflecting that their society stresses equality and opportunity. With Individualism score of 89, it reflects that as a society they believe in the rights of an individual rather and act as individuals rather than members of a group or as one society. The low ranking of 35 for Uncertainty avoidance shows that as a society they are less rule oriented, more accepting of ambiguity and are more readily to accept change. They have a more they go with the flow approach. With Masculinity score of 66, this reflects a culture that favors more traditional masculine roles of control, achievement, and power. With a score of 25 the Long Term Orientation people look more to the long term rather than the right now. It is more a bout looking more into the future and putting value in tradition and persistence. Population According to the Central Intelligence Agency World Factbook website the current population in the United Kingdom 63,742,977, placing it 23rd on the world country comparison list. The median age is 40.4, (Males 39.2, Females 41.6) and largest section of the population at 41% is 25-54 year olds; see the following pie chart for age comparisons. Of the major urban areas London is the most populated at 8.615 million, Birmingham second at 2.296 million and Manchester third at 2.247 million.

The United Kingdom is 29th on the world comparison chart for life expectancy the total population 80.42 years (males 78.26, Female 82.69). Form of government The form of government in the United Kingdom is that of a Constitutional Monarchy. Queen Elizabeth II is the Head of State in the United Kingdom; however her role is not that of a ruler of the country she fulfils important ceremonial and formal roles with respect to Government. David Cameron is the current Prime Minister and holds the senior minster role also considered the Head of Government and Head of the Executive Branch. Parliament is an essential part of United Kingdom government. The main roles of Parliament are legislation, debating and passing all laws, enabling the government to raise taxes and examine and challenging the work of the government. Parliament is made up of two houses, the House of Commons and the House of Lords, the two houses act as a check and balances system as decisions made in one house have to be approved by the other. The House of Commons is a publicly elected, the House of Lords members are appointed by the Queen.

These officials have important advisory and advocacy roles regarding legislative issues affecting the church such as abortion and euthanasia. The Church of England holds no authority in Scotland and unlike the Church of England the Church of Scotland is separate from the state. Negotiation In negotiations you must practice patience and do not try and rush your British counterparts into a decision. Do not use a hard-sell attitude or attempt pressure tactics, as this will only be counterproductive in your negations. When it comes to your business plans stick to the facts and do not over sell or schmooze, British executives are more concerned with the facts of the deal than the relationship. They are more concerned with the letter of the law than the spirit of law. British Executives tend to be direct and to the point, it is more about fact than feeling or emotion. They also tend to be very reserved and will rarely show emotion good or bad, and will often down play dangerous situations. Financial In 2008 the United Kingdom was hit with the Financial Crisis.

Failure of te Two-Party System Essay -- essays research papers

A valuable factor within any democracy is the presence of political parties. As dictated by Webster, a party is meant as "a group, which unites to promote or maintain a policy, a cause, or other purposes, as a political group." This definition can be easily simplified as individuals with a common cause. This is just the case with American political parties. They are ordinary groups of individuals with a common cause in hopes to gain political power. Within the United States, two political parties make up the majority, the Republicans and Democrats. Unlike many other democratic nations around the world, America is unique with their generalized lack of parties. However, there is a growing trend within America that implies the two-party system, which has been the leader in American politics, has started to become weak. When the United States initially formed as a nation, there were few differentiations between the people. Those with voting privileges were mostly white Anglo-Saxons. The greatest differences seemed to be developing around the issue of slavery creating a North versus South political atmosphere. Siding with the intelligence of the era, Thomas Jefferson and Alexander Hamilton, the federalist and anti federalist parties developed around opposing ideas regarding a written Bill of Rights. This form of elitism running the government was not unreasonable in a time when communication to the outskirts and rural areas of the nation wa...

Designer children should be available for families everywhere because it will help with disease prevention, give parents the choice of the traits for their child, and it will give scientists a better understanding of the continuously evolving science of embryology. Many families carry genetic diseases that, with the help of science, can easily be terminated. Diseases like juvenile diabetes, heart disease, AIDS, breast cancer, and sickle cell disease run in thousands of families today. Being able to take a closer look at DNA will give parents a chance to help expand their child’s life span. Parents everywhere would agree to have their child rid of any harm. The doctors would be able to access the egg or sperm and discard the specific gene. This alteration would last for generations to come. If the mother is able to attend doctor’s appointments while she is pregnant to check on the health of the baby, why not be able to cure the sickness before it is born, rather than waiting until birth? Today, not only could infertile parents get the chance to have a child, but also they can make sure it is safe and healthy. Genetic diseases can be devastating news to potential parents, but science can help reduce the likelihood of contracting it . Don’t people wish they were born with bright blue eyes?

What Goals Are We Trying to Achieve Through Sentencing? Essay

Alternative sentencing Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the recent years, use of other alternative options of sentences apart from incarceration is being advocated in United States and Canada among other countries as a way of solving the issue of congestion in prisons. Therefore, use of alternative sentencing will help in stabilizing the prison populations. Criminal sentencing should help in punishing and rehabilitating the criminal offenders so as to deter them from taking part in criminal activities again in the future. However, the prisons tend to focus more on punishing the offenders instead of rehabilitating them so as to change their behaviors. This reason has made the alternative sentencing options to be advocated so as to help in rehabilitating those offenders. Some alternative sentencing options which includes the punishments which are fairly innovative, involves requiring the offenders to stay at home under the house arrest, attending alcohol or drug treatment program, teaching cla sses or giving lectures concerning dangers of the criminal behavior, attending the weekend jail time, and installing the breathalyzer devices in personal cars, thus, ensuring that the cars only start when the offenders are not under alcohol influence.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Such sentencing options have many practical implications such as reducing the populations in the prisons, cost savings and effectiveness among other implications. Religion also condemns all manner of criminal evils that are carried out by the offenders. According to the Christianity, the bible clearly explains various evils and also ways of deterring from carrying out those criminal activities. According to Matthew 15-18, it shows how God is unhappy by those who commit the criminal activities. It states that out of the heart there comes the adultery, theft, murder, slander, sexual immorality and false testimony. All these evils make a person be unclean. American society is usually perceived to be built on values of Judeo- Christian. Torah does not advocate for the prisons and therefore it perceives the alternative options of sentencing to be the ideal way of punishing and deterring the offenders from committing such criminal activities aga in. Even in the Bible the offenders even those who committed murder were not imprisoned. For instance, in the land of Israel those offenders who committed murder were usually sent to the cities of refuge not for isolation, but for atonement purposes. In conclusion, the punishments of the criminal justice system should have positive results to benefit all the involved parties comprising of the victim, perpetrator and the society in general. Imprisonment does not serve the intended functions thus it does not benefit the victims. Prisons destroys families, inhibits the potential of the offenders, breeds anger, bitterness, insensitivity and the eventual recidivism. Therefore, innovative and alternative sentencing should be adopted as a way of solving all these problems which result due to the traditional sentencing. References Lipskar, R. S. (n.d.).

Analysis of newton’s second law lab

Law Lab The first lab we did for chapter 4, Newton's Second Law, dealt with the relationships between force, acceleration, and mass. Our goal was to verify Newton's Second Law that says force is equal to the mass multiplied by the acceleration. Our procedures included setting up the lab according to the directions and collecting data as someone moved the cart that we set up forward and backward in two settings – with additional mass and without additional mass.For the part where we had to attach mass, we observed that the mass can be rotated sideways as we did our data collecting, so we decided to fix its position with tape, which did not affect the significant digits of the mass. After we were done with both trials, we showed linear relationships for both the force vs†¦ Acceleration graphs. In our first trial, we had a . 629 keg cart and an equation of F=O. AAA+O. 1289; in our second trial, we had a 1 . 143 keg cart with the added mass and an equation of F=l . AAA-1. 075 . In the equations, F represented force and a represented acceleration.We observed in the equations that he slope of the graphs were equal to, ignoring the insignificant digits, the mass of the cart used in the corresponding trials. The data were viable; the observations that we had made perfect sense to us since we knew that force is equal to mass times acceleration. The y-intercept, however, was unexpected; y Intercepts were not present in the second law of Newton. The Increased/decreased force then, I presumed, must have been caused by discrepancies made from minor friction caused by the wheel of the cart. Experiments regarding these y-landscapes should also be Interesting future experiments.

M1A3 - Leadership and ethics - Essay Example It has a customer base that runs into millions per week and expeditiously boasts of workforce of over 500,000 employees (Wrigley, 1988). Jack Cohen founded the company in 1919. The name Tesco appeared first in 1924, but it was not until 1929 when the first store started its operations. The store was originally a UK grocery retailer, but it has diversified increasingly geographically and into other areas including electronics, petrol, clothing, furniture, books retail, financial services, software, internet services, and music downloads, DVD rental and telecoms. Tesco repositioned itself in the 1990s to Tesco Finest ranges (Tesco). This inevitably led to successful chain growth of the store from five hundred stores in the nineties to two thousand five hundred stores in 2005. Tesco’s Values sits at the heart of its business and helps the store to deliver its core purpose, which is to generate value for its treasured customers in order to earn their lifetime loyalty. The store af firms that it tries to its level best for its customers, treat people, as they would love to be treated in order to, fully enjoy their work (Bell & Reavis, 2003). The year 1997 was the year that these values were developed. Various touch ups have been done to perfect the values to align them to today’s business current trends. ... These stores stock all range of Tesco’s products although some of the stores are in middle of inner-city locations and town centers. Tesco Superstores are large standard supermarkets, which stock groceries and a smaller range of non-food products in comparison with Extra stores. Tesco Metro stores are mainly located in the inner city, in city centers and on high streets of towns. They are in between Tesco Express stores and Tesco Superstores in terms of size. Tesco Express sores are notably the neighborhood convenience stores that are found in residential areas, in the city centre districts, small villages and towns and in various Esso petrol stations (Tesco). According to Bell & Reavis (2003), One Stop stores do not have the Tesco brand name. The stores are to be found in smaller residential areas. There prices also differ from other Tesco stores. Tesco Homeplus are non-food only ventures, and there are 13 stores nationwide. The stores offer all of the Tesco’s items bu t with an exception of food. The stores have a style that is similar to a warehouse unit and are found in retail parks. Dobbies Garden Centers are 28 garden centers in total. This number is equally divided between the stores in England and Scotland. Tesco bought 65% shares of the Dobbies Garden Centers PLC in 2008. According to Woods (2012), other business activities that Tesco undertakes include Internet retailing, financial services, petrol stations, telecoms, photo shops, Tesco Tech Support, Technika, filmmaking, record label, video-on-demand, gold exchange, Tesco Tyres and beauty salon. The store made record profits of ?3.4 billion in the year 2010 despite the economy suffering the effects of recession. Tesco is

The Changing Role of Women In Society Today Essay

The Changing Role of Women In Society Today - Essay Example The days when the woman stayed at home and depended on their husbands for household and family responsibilities are being replaced by the scenario where the modern woman has become an equal if not a better contributor in these and other roles that were deemed to belong to men in the past. The advance of education has made women become enlightened and visionary, thus discovering their potential and importance in society. Education has revolutionized women from the notion of only being involved in domestic chores to join their male counterparts in becoming doctors, engineers, Presidents and Prime ministers, mathematicians, economists, teachers, winners of educational and other awards among many other fields. Roles that were branded as only being suited for males like serving in the army, the building industry, the space program and others are seeing the inclusion of women who are handling them with a lot of capability. The past saw women who pursued a career or an education as strange or whose ability to raise up children was hampered, or it was assumed that her husband was not able to provide adequately for his household. This has changed dramatically as women have taken opportunities available to them. Today’s woman has become powerful, independent, competitive , strong and respected in society, and their contribution in society has been immense (Colombo, Cullen, and Lisle, 521). The running of households which was under the control of the husband is now a shared responsibility because the wife’s new status enables her to make a contribution both intelligently and financially, improving the running of the home in this regard. Each of the partners is able to positively impact on raising up children in an enlightened environment, guiding them in their career paths in a world where knowledge is increasingly becoming power.

In the movie The Hurricane what was Ruben Hurricane Carter's Identity, Essay

In the movie The Hurricane what was Ruben Hurricane Carter's Identity, meaning and relationships with other chartecters - Essay Example Carter has personally authored the screenplay which is the reason why it fundamentally portrays the opinion of Rubin "Hurricane" Carter. The film portrays Carter as a passerby who is innocent and is not involved in the act of murder. According to the story’s plot, Carter was driving with a friend of his named John Artis towards home. They were on their way back from a club in Paterson when the police made them stop and inquired them about the murder of three people in a bar. The police’s suspicion was flared up by the claim of Alfred Bello that Artis and Carter were the witnesses of the act of murder. The police arrested Artis and Carter due to the allegations imposed by Bello upon the two and later, Carter was sentenced for life thrice. Carter maintained his position saying that he was being humiliated because of his African American race and his active participation in the civil rights movement. Despite the fact that Arthur Bradley and Bello recanted their allegation in 1974, Artis and Carter faced reconviction. Carter’s case was reinvestigated in 1980s by the state of New Jersey upon the insistence of Lesra Martin, a Brooklyn teenager who was working with activists from Canada. The Federal District Court decided in 1985 that the conviction of Carter happened solely because of racism.

The Importance of Communication Personal Statement - 1

The Importance of Communication - Personal Statement Example Since the research work was done as a group, there were challenges that were encountered in terms of different factors affecting the way the group was expected to perform and deliver the identified outcome. In every group endeavor, there were initial challenges in terms of aligning each member’s time, skills and abilities, and efforts toward the fulfillment of the group’s goal. In this particular situation, the goal was to come up with a comprehensive case study which focused on miscommunication during a funds transfer transaction within a bank setting. To do this, it was crucial to initially identify the competencies and capabilities of each member, as well as skills and talents. This is necessary to be able to assign roles and responsibilities and to equitably delegate tasks. Thus, during the process of group formation, members were able to agree on a group leader who governed all the tasks, roles, performance, and coordinating among members to ensure that various pha ses of the case studies are complied with effectively according to a definite time frame. Thus, at this particular phase alone, the challenges encountered were as follows: (1) carefully assessing skills, talents, abilities, and roles that each member would assume; (2) deciding who the group leader would be; (3) agreeing on the delegated tasks and responsibilities; (3) coming up with an outline of scheduled tasks to be delivered by each member depending on a time frame; (4) agreeing to meet or correspond on a particular schedule and venue; and (5) exchanging relevant personal details (names, addresses, contact numbers, and available schedules).

Ulster Solemn League and Covenant Essay Example | Topics and Well Written Essays - 1250 words

Ulster Solemn League and Covenant - Essay Example The Ulster unionists in 1912 believed that their situation was difficult although not completely lost. The leading Ulster unionists came to the conclusion that the Solemn League and Covenant and then the Ulster Volunteer Force were essential elements of preventing Home Rule leading to an independent Irish Republic dominated by Roman Catholics, their worst nightmare come true.1 The drawing - up of the Solemn League and Covenant amply demonstrated the general fear of the Ulster Protestants towards the Home Rule Act as passed by the British Parliament would be introduced throughout Ireland in 1912. The act was designed to provide Ireland with a high degree of autonomy, the Ulster unionists fearing it would sooner rather than later make Ireland an independent nation.2 The Ulster unionists did not want the granting of home rule for Ulster even if it was given to the rest of Ireland, as they wished to maintain their allegiance to the British crown. On the 28 September 1912, quickly dubbed Ulster Day, the solemn league and covenant was signed by more than 450,000 unionist supporters on the first day. The covenant publicly declared the Ulster unionist determination to stay loyal to the Crown and vehemently opposed the enforcement of home rule for Ireland as a whole.3 The Home Rule Act was primarily intended to give an Irish Parliament control over its internal affairs only' leaving it part of the United Kingdom. It would give the Irish autonomy whilst leaving defence, trade, and foreign to be run from London. The province of Ulster was made up of nine counties in the north-eastern part of Ireland with a Protestant majority. Another major factor was that Ulster had maintained its trade superiority over the rest of the Ireland. The unionists therefore, argued that Ulster needed to maintain its British and Protestant identity and the best way to do so were to remain loyal to the crown (the unionists are also refereed to as Loyalists). The moderate Irish nationalist leader was John Redmond the strongest advocate of Home Rule, and naturally enough argued that Ulster was included in Home Rule so that its heavy industry and generally successful commercial activities particularly in Belfast could be shared with the rest of Ireland. The Roman Catholics, who formed a majority of the Irish peoples, supported the autonomy that Home Rule would have granted them. Only a very small minority of Irish Roman Catholics supported the concept of a united Irish Republic completely free of British control and influence.4 The introduction of the Ulster Covenant, masterminded by Sir James Craig was subsequently signed by the vast majority of unionists they openly proclaimed their loyalty to the crown and were assisted by the Conservatives who worked behind the scenes to block or at least water down Home Rule legislation. The controversy over David Lloyd George's Peoples Budget of 1909 had the unforeseen consequence of inadvertently delaying the legislation for Irish Home Rule whilst the Parliament Act was passed to curb the power of the House of Lords. The crisis over the Peoples Budget gave the opponents of Home Rule in Ulster particular the opportunity as well as the time to organise resistance to its adoption. They were helped considerably by the Conservativ

My Family History Essay Example for Free

My Family History Essay In all of us there is a hunger, marrow deep, to know our heritage to know who we are and where we came from. Without this enriching knowledge, there is a hollow yearning. No matter what our attainments in life, there is still a vacuum, emptiness, and the most disquieting loneliness. † –Alex Haley This quote explained to me the importance of my grandparent’s legacy and their history. A long twisting family tree inspires one who does not know where their roots originated. My grandfather Frank Douglas and my grandmother Delores Jones gave me a reason to find out where our legacy started. My grandfather Frank Kelow was adopted into a four person white family, which gave him the last name of Douglas. My grandfather was born on February 12, 1902. Frank was raised in Greenville, Mississippi with dozens of cousins, which gave him comfort. Frank’s biological parents did not attend college; in fact, they didn’t even graduate from high school. In Mississippi, â€Å"I was surrounded by racism, slavery, and poverty, which gave me the inspiration to give my father a better life† (Douglas). As a young kid Frank often hung out in the streets with his friends and partied a lot. He was a heavy smoker with a tiny taste for alcohol. â€Å"Growing up in a poor neighborhood I was introduced to a lot of bad things such as drugs, gambling, and fighting† (Douglas). Around the house, Frank was responsible for mowing the lawn, taking out the trash, and cleaning the pool. At the age of 21 my grandfather entered the army and decided to fight in World War II. After the war concluded, my grandfather married and moved to Queens, New York. Frank and his wife made history that day because they were the first black couple to move into the neighborhood, which they lived. This was the birthplace of my father Lance Douglas Sr. My grandmother Delores Jones was born on December 14, 1906, into a family of four. She was also raised through poverty, but with the help of her brother and cousins she found a way to stick it out. She was raised in New Orleans, Louisiana where her parents worked several jobs to maintain the tiny shack she was raised in. â€Å"Back in my day society consisted of smoking cigarettes, drinking beer, and partying heavily† (Jones). At the age of 13, she was required to work to earn extra money around the house. Some chores my grandmother had around the house was to clean the house, wash the dishes, wash clothes, and pull weeds from the lawn. The relationship between my grandmother and her parents was quite the opposite of mine with my parents. â€Å"After completing my chores, I was allowed to do basically whatever, as long as I was in the house at a reasonable hour† (Jones). Delores was a very social person. â€Å"I rarely spent time with my grandparents† (Jones). During her high school years she was often looked at as beautiful, ambitious, and persistent. At the age of 18 she was elected as prom queen for her senior dance. Although she was often free to do what she wanted, she was also held responsible. Delores was sometimes whooped and grounded for disobeying curfew rules and not completing her chores. This gave her everlasting the mentality of you must work for everything you want in life. I was born in Mississauga, Canada on the date of February 23, 1993. The name Kobie was given to me by my mother, it means warrior. Raised in a family with both parents, one-brother, and one sister, I was surrounded by people who loved me. My brother, Lance Douglas, was born four years earlier than me. Likewise, my sister was born two years prior of my birth. At the age of two, my parents decided to move to Plano, Texas, a beautiful city with the population of about 700,0000 people. As usual, around five I attended Kindergarten at the local school where my brother and sister attended elementary school. Being the youngest in the family provided both advantages and disadvantages. My brother and sister inherited my father’s gene of aggravating me to the point of physical confrontation, which later led to me getting beat up. Although women are usually on the feminine side, my sister was completely different. When my teenage years came around that’s when my siblings began to lighten up on the bullying. During my high school years I was considered the man on campus. I was an all-star at basketball, football, and baseball. During my senior year I only participated in football and was offered a scholarship to play for the Louisiana Lafayette, Ragin Cajuns. Now, as a freshman at the University of Louisiana at Lafayette I am living the life I once dreamed about; experiencing things I never thought I would. For example, going to the club on Mondays, Wednesdays, Fridays, and Saturdays. A student athlete who is enrolled in 17 hours and is also committed to football. Waking up at five a. m to workout on Mondays, Wednesdays, and Thursdays. Most of all, living the dream people told me wasn’t meant. All across the world there are families who have their own original legacies. In all of us there is a hunger, marrow deep, to know our heritage to know who we are and where we came from. Without this enriching knowledge, there is a hollow yearning. No matter what our attainments in life, there is still a vacuum, emptiness, and the most disquieting loneliness (Haley page 1). Its up to one to figure out how and where their family started. My grandfather Frank Douglas and my grandmother Delores Jones gave me a reason to find out where our legacy started. My grandparents have told me many things I never thought I would know about which has expanded my knowledge for the better.

Routing Protocol Simulation With NS2

Routing Protocol Simulation With NS2 Network simulation is a method of investigation in network technology. In the process of investigating a new technology, due to various reasons, it is costly and unrealistic to physically test a network system. In such situation, simulation becomes one of the best available solutions in testing, evaluation and validation. Network simulation has the features of small cycle and low cost, and it is easier for researchers to use others research, in order to concentrate on the particular part and no need to waste too much time on other part of the system. NS2 is a simulation platform that is developed in free open source for network technologies. Researchers can easily use it for the development of network technology. Until today, NS2 contains rich modules that are almost related to all aspects of network technology. Wireless network communications obtained a rapid development in recent years. Ad hoc networks do not need the support of cable infrastructure; the communication is achieved by free mobile network hosts. The emergence of ad hoc network has promoted the achievement of the process of free communication at any environment, at the same time it has also provided an effective communication solution of military, disaster relief and temporary communications. Considering the ad hoc network is constantly moving, and the network topology is changing, therefore the traditional internet routing protocols (e.g. RIP, OSPF) are not be able to adapt into the actual need of ad hot networks. Therefore there are many specialised routing protocols are designed for the ad hoc network, the aim of this paper is to compare, analyse and evaluate the most popular routing protocols for ad hoc networks by running the simulation test with NS2. Introduction A mobile ad hoc network (MANET), sometimes called a mobile mesh network, is a self-configuring network of mobile devices connected by wireless links. Along with the desire of get rid of the wired network constraints and be able to communicate at any time and any place, wireless network communications obtained a rapid development in recent years. Mobile communications can be achieved by portable computers with wireless interface equipped and PDAs. Most current mobile communications require a wired infrastructure, e.g. base station. To be able to communicate without fix infrastructure, a new network technology Ad Hoc network technology arises at the historic moment. Ad hoc networks do not need the support of cable infrastructure; the communication is achieved by free mobile network hosts. The emergence of ad hoc network has promoted the achievement of the process of free communication at any environment, at the same time it has also provided an effective communication solution of military, disaster relief and temporary communications. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. Ad-hoc network was originally used in the military field. With the developments of wireless networks, it has begun the development in the civilian fields. A mobile ad-hoc network does not need any infrastructures, any node can quickly and automatically form the network, and each node can move freely and is able to join or leave the network at any time. The characteristics and advantages of fast deployment, invulnerability makes mobile ad-hoc becoming more and more widely used in either military or civilian fields. In recent years, as the emerging wireless communication network, Ad-hoc is gradually attracting more attention of the industry and become a research hotspot. Ad-hoc networking supports flexible and convenient communication without the support of infrastructure, this technique broadens the fields of mobile communications and has a bright future. Ad hoc network can be regarded as the cross of mobile communication and computer network. In ad hoc networks, computer network packet exchange mechanism is used rather than circuit switching mechanism. Communication hosts are usually portable computer, personal digital assistants (PDA) and other mobile devices. Ad Hoc network is different from mobile IP network in the current Internet environment. In mobile IP networks, mobile hosts can link and access the network through fixed wired network, wireless link and dial up link, and in ad hoc network, these is only a wireless link connection. In mobile IP networks, the communication need to be supported by adjacent base stations and still using the traditional internet routing protocol, however, ad hoc networks do not have the support of these facilities. In addition, a mobile host in the mobile IP network is only an ordinary end device which does not have routing function. When the mobile host moves from one zone to another does not chan ge the network topology, and in Ad Hoc networks the movement of mobile hosts would lead to topology change. The thesis is to research on the Ad-hoc networking mode and its network layer through simulation with NS2, mainly focused on the comparison and analysis of the popular ad-hoc routing protocols. The aim of this article is to research and develop on the key technology of self-configuring network routing protocols, based on ad-hoc network structure. Wireless Ad-Hoc network Structure and Characteristics Ad Hoc wireless network has its own particularity, in the formation of actual use of the working network, the application size, scalability and the reliability and real-time requirements must be taken full account. In addition, due to the unique structure of the ad hoc network, the characteristics of ad hoc network should be fully considered when design and build the network, which will help us to design a routing protocol that is suitable for particular network structure in order to maximise the performance across the network. Ad-hoc network Structure Ad Hoc wireless network topology can be divided into two kinds: Flat structure and hierarchical structure, in flat network structure, all network nodes have equal status. However, in the hierarchical structure of the Ad Hoc wireless network topology, the whole network is composed of clusters for the subnet, each cluster consists of a cluster head and multiple cluster members, the cluster heads forms a higher level network. Each cluster head and cluster members are dynamic and automatic networking. The hierarchy is based on different hardware configurations, and hierarchical structure can be divided into single-band and multi-band classification structure. Single band hierarchy use single frequency in communication, all nodes use the same frequency. But in multi-band hierarchy, if there are two networks in different levels exist, the lower level network has a smaller communication range and higher level network has a larger communication range, cluster members use the same frequency to communicate, cluster head nodes uses one frequency to communicate with cluster members and another frequency to maintain the communication with cluster heads. There are advantages and disadvantages exist in either flat or hierarchical network structures: the structure of flat structure network is simple, each node has an equal status, there are multiple paths exist in communication of the source node and destination node, therefore no network bottlenecks, and the network is relatively safe. However, the biggest drawback is the limited network size, when the network scale expanding, routing maintenance overhead exponential growth and consume the limited bandwidth; Hierarchical network structure is not limited by the scale of network, the scalability is good, and because of clustering, routing overhead is relatively smaller, although there is the need of complex cluster head selection algorithm in hierarchical structure, but because of hierarchical network structure with high system throughput, node localisation is simple, therefore ad hoc network is now increasingly showing grading trend, many network routing algorithms proposed are based o n the hierarchical network structure model. Ad-Hoc network Characteristics Wireless ad hoc network is a combination of mobile communications and computer networks, each node in the network have both router and host functions. The characteristics of ad hoc networks in mainly in the following areas: Dynamically changing network topologies: Ad Hoc networks have no fixed infrastructure and central management communications equipment, network nodes can randomly move to any direction in any speed rate, coupled with the power change of wireless transmitter device, the environment impact and the signal mutual interference between each other, which all will result in dynamic changes of the network topology. Limited resources: the working energy provided to the mobile hosts in Ad Hoc networks are limited, and the mobile host with more energy loss, will reduce the Ad Hoc network functions; on the other hand, the network itself provides limited bandwidth and signal conflicts and Interference, which results the mobile host with limited available bandwidth which is normally far less than the theoretical maximum bandwidth. Multi-hop communication: if two network nodes are not in the same network coverage due to the limited resources available, multi-hop may be used in Ad Hoc network communication, in order to achieve the communication between the source host and destination host which are not in the same network coverage. Limited physical security: the communication of Ad Hoc network nodes are through the wireless channel, the information transmitted is very vulnerable, and eavesdropping, retransmission, falsify or forgery attack can be achieved easily, If routing protocol once suffered the malicious attacks, the whole self-organizing networks will not work properly. These features of the Ad Hoc network have made a special request in the routing algorithm design. A reasonable routing algorithm must take the factors of limited network resources, dynamic network topology changes and improve the network throughput into account. Ad-Hoc Wireless network routing protocols The key issue in ad hoc network design is to develop a routing protocol that is able to provide high quality and high efficient communication between two nodes. The mobility characteristic in the network makes the network topology constantly changing, the traditional internet based routing protocol is unable to adapt to these characteristics therefore the routing protocol that is specialised for ad hoc networks is needed, According to earlier on the Ad Hoc network architecture and features described, the design of the routing protocol must meet the following conditions: The need of rapid response capability for dynamic network topology, and try to avoid routing loops from occurring, and provide simple and convenient network node localise method. Must be efficiently use of the limited bandwidth resources, and try to compress unnecessary overhead. Limit the number of intermediate transfer during the implementation of multi-hop, generally not more than 3 times. Must minimise the launch time and amount of launch data, in order to save limited working energy. In possible conditions, make the design of routing protocol with securities to reduce the possibility of being attacked. Routing Protocols According to the specific characteristics of ad hoc wireless network routing protocols, in recent years, there are a variety of ad hoc network routing protocols have been proposed. IETFs MANET working group is currently focused on research Ad Hoc network routing protocols, and protocols many protocol drafts, such as DSR, AODV, ZRP etc. in addition, the professional researchers also published a extensively amount of articles related to Ad hoc network routing protocols and proposed many network routing protocols for the ad hoc networks, such as DSDV, WRP etc. According to the routing trigger principle, the current routing protocols can be divided into three types: Proactive Routing protocol, Reactive routing protocol and Hybrid routing protocols. Proactive Routing protocol Proactive routing protocol is also known as Table-driven routing protocol, each node maintains a routing table that contains the routing information to reach the other node, and updates the routing table constantly according the network topology changes, and therefore the routing table can accurately reflect the topology structure of the network. Once the source code needs to send messages, the route to the destination node can be immediately obtained. This type of routing protocol is usually modified from the existing wired network routing protocol to adapt to the wireless ad hoc network requirements, such as the Destination-Sequenced Distance Vector protocol, which is modified from the Routing Information Protocol (RIP). Therefore, this type of routing protocol has a small delay, but requires a lot of control message, the overhead is large. Commonly used proactive routing protocols include DSDV, HSR, GSR, WRP etc. Destination-Sequenced Distance Vector (DSDV) DSDV avoids the generation of routing loops by set serial number for each route, using time-driven and event-driven technology to control the transfer of routing table, i.e. a routing table is kept in each moving node locally, it contains valid points, routing hops and destination routing serial number etc. destination routing serial number is used to distinguish old and new route to avoid routing loops. Each node periodically sends the local routing table to the neighbour nodes, or when the routing table changes, the information will also be passed to neighbouring nodes, when there is no moving nodes, use a larger packet with longer interval to update the route. When the neighbouring node receives the information contains modified routing table, it will first compare the serial number of destination node, the routing with larger serial number will be used and the one with smaller serial number will be eliminated, and if the serial number are the same, the best optimised route (e.g. shortest path) will be used. Each node must periodically exchange the routing information with adjacent nodes, the routing information update is also can be triggered by the changes in routing table. There are two ways to update the routing table, Full dump, i.e. the topology update message will include the entire routing table, which is mainly applied to the case of fast changing network. Another way is Incremental update, in which update message contains only the changed part in routing, such way is usually used in a network with slower changes. Hierarchical State Routing (HSR) HSR is a routing protocol that is used in hierarchical network, nodes at a higher level saves all the location information of its peers, logical sequence address is assigned along from the root node at the highest level to the leaf node at the lowest level, node address can be used by sequence address. Global State Routing (GSR) GSR protocol works similar with the DSDV mechanism, it uses link-state routing algorithm, but avoids the flooding of routing packets, which includes an adjacent node table, network topology table, next hop routing table and the distance table. Wireless Routing Protocol (WRP) WRP is a distance-vector routing protocol, each node maintains a distance table, routing table, link overhead table and packet retransmission table, through the Short Path Spanning Tree (SST) of the neighbouring node to generate its own SST, and then transmit updates. When there is no any change in the network routing, the receiver node must return an idle message to show the connection, otherwise modify the distance table to look for better route. The feature of this algorithm is that when any changes of the neighbouring node is detected, and then checks the sturdiness of all adjacent nodes in order to eliminate the loop, has a faster convergence. Reactive Routing Protocol Reactive Routing protocol is also known as on-demand routing protocol, it finds the route only when needed. Nodes do not need to maintain routing information constantly, it will initiate route look up only when the packet is need to be sent. Compare with proactive routing protocols, the overhead of reactive routing protocol is smaller, but the packet transmission delay is larger, which means it is not suitable for real time applications. Commonly used reactive routing protocols include AODV, DSR, TORA and so on. 2.2.2 Dynamic Source Routing (DSR) DSR is designed to restrict the bandwidth consumed by control packets in ad hoc wireless networks by eliminating the periodic table-update messages required in table-driven approach. DSR is composed of two main mechanisms Route Discovery and Route Maintenance. The Route Discovery mechanism is used when the source node needs to send a packet to the destination node but does not know the route. When the source node is using a source route to reach the destination node, source node uses the route maintenance mechanism to identify the route that cannot be used due to the topology changes. In DSR, route discovery and route maintenance mechanisms are fully on-demand operation, DSR does not require any periodic routing broadcast packets and link state detection packets. 2.2.3 Temporally Ordered Routing Algorithm (TORA) TORA is an adaptive distributed routing algorithm based on link reversal method, which is mainly used for high-speed dynamic multi-hop wireless network. As a source initiated on-demand routing protocol, it is able to find multi-paths from the source to the destination node. The main characteristics of TORA are, when topology changes, the control message transmission in local area of topology changes only. Therefore, the node only needs to maintain the information of adjacent nodes. The protocol consists of three parts: route generation, route maintenance and route deletion. In the initialisation stage, the transmission sequence number of the destination node is set to 0. The QRY packet which contains the destination node ID broadcast by the source end and a node with a transmission sequence number that is not 0 responses to the UDP packet. The node that receives UDP packet has the sequence number higher than the source node by 1, and the node with higher sequence number is set as the upstream node. Through this method, a Directed Acyclic Graph (DAG) from the source to the destination node can be created. When nodes move, routes need to be rebuilt. In the route deletion phase, TORA removes the invalid route by broadcasting a CLR. There is one problem that exists with TORA, which is when multiple nodes proceeds to route selection and deletion, routing oscillation will be produced. 2.2.4 Ad-hoc On-Demand Distance Vector Routing (AODV) AODV is an improvement to the DSDV algorithm, but the difference with DSDV is that it is a Reactive routing protocol. In order to find the route leading to the destination node, the source end will broadcast a routing request packet, and adjacent in turn broadcast the packet to the surrounding nodes until the packet was sent to the destination node, or, to the intermediate node which has the routing information to the destination node. A node will discard duplicated request packet received, the serial number of routing request packet is to prevent routing loops, and is able to determine whether the intermediate node has responses to the corresponding routing requests. When a node forwards a route request packet, it will mark the ID of its upstream node into the routing table, in order to build a reverse route from the destination node to the source node. When the source end moves, it will re-initiate route discovery algorithm; if the intermediate nodes move, then the adjacent node wi ll find the link failure and send the link failure message to its upstream node and spread the message all the way to the source node, afterwards the source node re-launches the route discovery process according to the circumstances. The achievement of AODV is a combination of DSR and DSDV protocols. It has the features of route discovery and route maintenance in DSR, and at the same time use by-hop routing, sequence number and Beacon messages that adopted in DSDV. Hybrid Routing Protocol In wireless ad hoc networks, neither proactive nor reactive routing protocols alone can solve the routing problem completely, therefore hybrid routing protocols which combines the advantage of both proactive and reactive protocols have been proposed by the researchers, such as the Zone Routing Protocol (ZRP). ZRP is a combination of proactive and reactive routing protocols, all nodes within the network to themselves as the centre of a virtual zone, the number of nodes in the area is related to the radius set of the zone, and the areas overlap, this is the difference with clustering routing. It uses proactive routing algorithm within the zone, the centre node uses Intrazone Routing protocol to maintain in the zone. Literature Review Network Simulation Tool The platform that will be used in simulation is Windows XP Professional + Cygwin + NS2. NS2 is a simulation platform that is developed in free open source for network technologies. Researchers can easily use it for the development of network technology. Until today, NS2 contains rich modules that are almost related to all aspects of network technology. Since the release 2.26, NS2 has stopped support with Windows platforms, therefore to get the latest NS2 running on the Windows XP, Cygwin is needed. Cygwin is an UNIX emulator on Windows platform. Implementation Configure simulation platform Normally, NS2 simulation can be divided into the following steps: 1. Compose necessary components: i.e. add or remove new components 2. Testing: test whether the component composed is validated. When the component in the library satisfies the simulation needs (e.g. simulation process based on existing protocols in the library),then the simulation starts from the third step. 3. Compose Otcl script file: configure the topology structure of the simulating network, and identify the basic link features, protocols that have been used by moving nodes, and number of nodes etc, and binding the terminal device protocol, setting the scene and traffic load of simulation (TCP stream or CBR stream), setting simulation start and end time etc, and set trace objects of the script file, trace file is the file that records all of the events of simulation process, and also can set the nam object at the same time, nam is the tool to demonstrate the network running animation. 4. Use NS command to execute script file: once executed, *.tr file will be generated in the same directory of the script file, to record the simulation results. if nam object is set in the script file, *.nam file will be generated in the same directory. 5. Analyse trace file: due to the large size of trace file, we will need to compose gawk program to process the data after simulation (calculate packet delivery date, routing overload, and throughput etc), then use the drawing tools to produce the graph for direct analysis. In NS2 the classic routing protocols such as DSDV, DSR, TAORA and AODV are already integrated; the source code of routing protocols is located in C:cygwinhomeAdministratorns-allinone-2.34ns-2.34, show in figure 1.1 Take AODV as an example (fig. 1.2), within the ADOV folder, aodv.cc and aodv.h are the most important files, they defines the main functional features. Under general circumstances, we do not need to modify the source code of the protocols. Fig.1.2 AODV Routing Protocol Simulation scripting According to the simulation model designed, each routing protocol (DSDV, DSR, AODV, and TORA) will be compared in small (20 nodes) and medium (50 nodes) ad hoc wireless network. The corresponding scripts composed are: dsdv.tcl, dsr.tcl, aodv.tcl and tora.tcl (see appendix). Taking aodv.tcl as an example, the coding is show in fig.3.2.1 Partial scripts in aodv.tcl Some script explanation of most important codes in aodv.tcl set val(ifq)Queue/DropTail/PriQueue; #Interface queue set val(nn)50; #Number of nodes in simulation scenario set val(rp)AODV; #Routing protocol to be simulated set val(stop)300 #Simulation time length set val(x)500; #Length of scene set val(y)500; #Width of scene set val(tr) out50.tr #Output trace file set val(nam) out50.nam #Output nam file set opt(cp) cbr50 #Stream file set opt(sc) scen50 #Scene file In addition, write the following statement in script head to generate a simulation ns_ object: set ns_[new Simulator] Tracking the file object is used to specify the Trace file (with .tr extension) in recording of the simulation data. NS2 supports record application layer, routing layer, MAC layer and node movement those four types of data in difference layers. The data that needs to be recorded can be specified in settings in the simulation process. The data in of each layer that trace object specified are all recorded in the trace file, labels are added to distinguish them. In addition, NS2 also supports NAM tool simulation process visualisation, such function needs to generate the NAM trace file object to specify the trace file of records of simulation data. The following statements are used to generate those two trace file object described. #Generate trace file: $ns_use-newtrace set tracefd[open out50.tr w]; $ns_trace-all$tracefd #Generate NAM trace file object: set namtracefd[open out50.nam w] $ns_namtrace-all-wireless$namtracefd$val(x)$val(y) Data Stream Generation Tool Data stream generation tool cbrgen is used to generate traffic loads, which can generate the TCP steam and CBR steam. Cbrgen.tcl file (see appendix) can be used as following: Codes are defined as following: -type #TCP stream or CBR stream -nn #Number of nodes -seed #Specify number of random seeds -mc #Maximum connection of each node -rate #Overload of each stream connection The format is used as following: ns cbrgen.tcl [-type cbr|tcp] [-nn nodes] [-seed seed] [-mc connections] [-rate rate] Movement Scene ./setdest is used to randomly generate the nodes movement scene needed form wireless network, used as following (2 versions): ./setdest -v -n -p -M -t time> -x -y or ./setdest -v -n -s -m -M -t -P -p -x -y Which speed type set to uniform/normal ¼Ã…’pause type set to constant/uniform. NAM animation The NAM function is used to run the animation of specific trace output format, the output file can be based on real or simulated environment. For example, the trace file that is from the output of NS simulator. The commands to control to control NAM animation in NS2 as following: nam out.nam 1.

Qualitative indicator describes the overall performance of a particular aspect of the network, such as the security, distribution operation, provide loop free route and whether to support single channel etc. and quantitative indicators can describe the performance of a certain aspect of the network in more details. The quantitative indicator of packet delivery ratio, average end to end delay and throughput etc are often used to measure the performance of network routing protocols. a. Packet delivery ratio: is a ratio of the number of packet sent from the source node and the number of packet that have been received by destination node in the application layer, which not only describes the loss rate observed in the application layer, but also reflect the maximum throughput supported by the network. It is the indicator of routing protocol completeness and correctness. End to end average delay: it can be calculated with the following equation, which N represent the packets successfully delivered, rt represents the time that packet reached the destination node, and st represent packet sending time. Routing overhead: Routing overhead is the total number of control packets of all routes, in a multi-hop routing each hop transmission is equivalent to one packet transmission. Routing overhead can be used to compare the scalability, the ability to adapt to network congestion and the efficiency of different routing protocols. It can be calculated with the following formula: Routing overhead = The Total number of routing control packets Gawk code The output file out.tr generated in simulation analysis will be filtered by selecting all of the packets in Agent layer, calculate all the number of data packets sent by this layer and the number of data packets that has been successfully received, and then divide the number
