System Design Methodology Essay Example for Free

System Design Methodology Essay Newbiz Telecommunication Services is a company that sells mobile phones, mobile accessories, prepaid cards and other items related to telecommunications and mobile computing industry. The company intends to develop a system to manage its inventory needs. This system will be used by the company’s staff and management to monitor the movement of its stocks. Among the many reasons why the system is required are: a. The system enables the company to reduce labor and paper costs since many of the daily functions will then be automated. b. It allows employees to concentrate on their jobs rather than spending time on searching records. c. Human errors can be reduced e.g. calculation error might lead to wrong billing to the customers. d. It allows the company to keep track of its stock levels as late replenishment of inventory can result in insufficient stocks to meet customer demands. e. The time it takes to process sales to customers can be made faster. Faster response time means that sale of items can be quickly closed. f. It presents a good image to the company’s clients leading to more confidence in the company. This allows it to gain a competitive advantage over its competitor. g. Inventory levels can be closely and easily watched with the new system as the management has better control over inventory levels. This is because inventory levels are updated every time a sale to customer is made and whenever new stocks arrive.

Argumentative Essay: Gun Control Violates the Second Amendment :: Constituton Bill Rights Right To Bear Arms

Few issues incite americans more than the issue of rising crime and violence. This problem can easily be linked to the availability of guns."The debate over whether guns are a hallowed tradition and a right guaranteed by the Second Ammendment of the U.S.constitution or whether they are a fearful danger contributing to crime and violence." ("gun control") Due to the outbreak of violence in our society, some people feel that repealing the Second Ammendment would solve the problem. These people feel that repealing the Second Ammendment would solve the problem. These people feel that there are two reasons for the repeal; One is the rising of violence among teenagers, the second reason is their interpertation of the Second Ammendment which could be considered a strict one. The side opposing these views use arguments like how it would be immpossible to repeal the Second Ammendment, and a long western civilizations history with a right to bear arms. Finally one can see the conflict of views dealing with the Second Ammenment, but one would also see that repealing the ammendment wouldn't solve the problem facing our society. The contriversy of this issue that has the potential to pulverise this country is why it is such a good topic to discuss, people should be better informed and make a decision based on fact and not fiction. Many advocates of the limitations of guns can quote numerous examples of increasing violence and homicide crimes. But the area which hits the closest to home is the issue of violence among the teenagers of our society. The years have changed on how students deal with their problems "Twenty-five or thirty years ago, when teenage boys got into a fight... it usually meant a fist fight. In more and more neighborhoods... it now means a shoot out" ("Gun Control"320). Violence like that is a major problem on our streets and even in our schools. Almost everywhere now "youngsters are packing weapons, Some are involved in drugs or gangs; others carry them for self-defense... One study says at least one in every three male juveniles is armed"(Muller 2). Now more than ever before an "increasing number of children under the age of 18 arrested each year for murder has jumped 55% in the past decade,... Juvenile arrests for aggravated assault are rising dramatically" (Henkoff 2). The results of this rising trend in violence has led to the release of a "center for disease center reports that since 1988, American teenage boys have been more likely to die from gunshot wounds than from... All other natural diseases" ("Gun Control" 83).

Analysis of a Dream of China by Ovidia Yu

Task 2: Written Assignment A Dream of China by Ovidia Yu A Dream of China is written by Ovidia Yu, a Singaporean writer during the 1980s. This story talks about a woman who grew up with many stories revolving around China. The stories were told by her father who was from a wealthy family. He and his brother joined the army to fight off the Japanese in Singapore and were disowned by their father for doing so. After the war ended, the narrator’s father decides to stay in China while the brother chose otherwise. For this choice, the father feels extremely guilty throughout the years.Being convinced that China was amazing, the narrator grabs the opportunity to visit China and finds out for herself many things that differ from her father’s stories. According to Oxford Dictionary (2010), criticism is defined as the analysis and judgement of the merits and faults of a literary or artistic work. Literary criticism therefore, means judging of literary works for both the good and bad. According to a handout of Twentieth-Century Literary Theories, there are many different kinds of literary criticism which include Formalism, Reader-Response, Sociological, Historicism, Structuralism and Psychoanalytic.Several of the mentioned theories are applicable to this text by Ovidia Yu while the others are not very suitable. One of the literary theories that are applicable to A Dream of China would be Reader-Response Criticism. As the handout describes, reader-response criticism is a critical view that sees the reader’s interaction with the text as central to interpretation. This criticism involves the reader’s elucidation and opinion towards the text because as different readers read it, they will have expectations.From those expectations, there lies a perfect explanation in the back of the reader’s mind. The beauty of it is, nobody has the exact same opinion and that is where variety of interpretations could be established. Collaboratively, these r esponses could be put together to criticise a text completely from the inside out, covering all aspects of the text. My response towards this text will be regarding the theme of the text which is an unnecessary guilt of a father. The narrator’s father’s choice of staying in Singapore after the war is a rational one ecause he has already settled down unlike his brother who was still unmarried then. â€Å"He had a wife and my eldest sister, who was already born,† (p163) perfectly justifies that the father’s choice of staying was a rational one. I believe that any man caught in that situation would make the exact same choice he did as it was the best choice available. Besides that, after the Japanese left Singapore and China, staying in Singapore was a smarter choice as it was much smaller thus, suffered less damage compared to China which is many times bigger and of course, more severely damaged.Furthermore, Singapore remains the trading hub of overseas tra ders which gives the place that much more advantage in its nation’s recovery and growth compared to China. With such advantage in the nation and a weight of responsibility towards the family, I would not see how one father would choose otherwise. This is proven the right choice again by the narrator during her expedition to China when she finally meets her nobly described uncle who turns out to be a ‘drab old man’ (p173), ‘barely tolerated by people’ and ‘children throw names at him’ (p170).All in all, they contribute and directly support the theme ‘unnecessary guilt of a father’. Another suitable literary criticism theory would be historicism. Historicism focuses on a text in relation to the historical and cultural contexts of the period in which it was created and critically evaluated. In the case of this text, it is written in the 1980s. During this time, Singapore has already made great progress with their countryâ€℠¢s development and is far more organised and modernised compared to China then in which some parts still live in extremely poor conditions.The narrator’s father however, settled in Singapore around 1945 as that was the year the Japanese left Singapore. At that point of time, Singapore as mentioned above stands a greater chance of recovering their loss and move on with development of their tiny country whereas China is so vast and was undergoing post-war clashes politically at that time. In 1946, civil war in China erupted yet again. With such circumstances, it is of no doubt that the narrator’s father, who was married and had a family living in a peaceful developing country, chooses to stay.Going back to China at such times would only be asking for trouble. This is also one of the reasons why the father feels guilty. It would be because he let his own brother make the unwise choice without trying to make him stay as stated in (p170) ‘If my father had only given h im a word of warning he would now be in Singapore living in the lap of luxury†¦ ’ In the 80s when the narrator finally visits China, which was then undergoing another reform related to communism of Mao-Zedong, she met her noble uncle who turned out to be dull, arrogant, rude and living in poverty, hated by most of the villagers.Seeing such sight would make anyone compare with their own home, in this case, Singapore, which was far more modernised and civilised where husbands treat their wives as equal in status and power unlike in Sechuan where the narrator’s uncle still ‘swore continuously at his wife’ (p169). Even now, we can still see how staying in Singapore would be the best choice at that time. In this 21st century, Singapore has become one of the most modernised countries competing alongside Japan as well as America.While in mainland China, some parts are much modernised, but many other parts are still, till this day, without electricity and wat er what more to say, education. In conclusion, both theories of literary criticism has their unique own way of approach towards literary works. The choice of theories is still ultimately up to the readers to choose which is most suitable. Without literary criticism, literature would have lost their art form that has been appealing to linguists for centuries, similar to how art would lose its value if nobody cares to analyse and evaluate it.

Rousseau s Views On The State Of Nature And Civilization

In this essay, I will compare the contrasting views between Thomas Hobbes and Jean Jacques Rousseau based on the state of nature and civilization. Rousseau was seen as an optimist who viewed human nature as good (â€Å"Noble Savage†) and believed that civilization corrupted us; While, Hobbes thought the complete opposite believing that humans in their natural state were selfish creatures purely interested in themselves and that government is imperative in keeping us in check. Throughout this essay, I will further explain their differing ideas and I will show how I view and interpret them as well. As I’ve stated before, Jean Jacque-Rousseau and Hobbes have contrasting views when it comes to the state of nature. Rousseau held an optimistic view of the state of nature. He viewed humans who lived in early times as â€Å"Noble Savages† and that man was â€Å"naturally good.† Rousseau viewed individuals who lived in a state of nature were happier, healthier, self-sufficient and had the freedom to do as they desired. To live in a state of nature was to live a simple life focused on family, self-love, and self-preservation. Rousseau believed we were better off in a state of nature, where as civilization corrupts us. Had Thomas Hobbes been alive during Rousseau’s time, or vice-versa, they would have been the greatest of rivals.
