Security analysis - Essay Example fund managers from the United Kingdom have made efforts to invest in China since its economic growth rate is significantly higher compared to other countries in the world. It is imperative to note that investment fund managers are driven by the potential rate of return from a given region, and this is the motivating factor for choosing an investment destination. One of the advantages of investing in China is the magnitude presented in the potential of its market. Foreign ventures and businesses set up investments in order to serve a local market. The market size and growth rate opportunities are some of the key factors in the determination of an investment destination. Essentially, investors target unexploited markets that are of a significant size with potential for growth. Therefore, countries that have large markets and growth potential are viable investment destinations. The Chinese population of over one billion people offers a large market for any industrial products (Malkiel et al., 2010). In fact, the huge population has a great consumption potential that can be harnessed for business gain. In the recent past, the purchasing power of the Chinese population has also increased significantly, scaling up the uptake of goods and services. Therefore, the large population of the Chinese region attracts fund managers to invest in the region due to the potentially huge market that population offers. Imperatively, China is a prime location for any investor to pump financial resources into as the prospect of getting a market for the goods and services produced is high. The infrastructural development of a region has an influence on the economic growth of the place. The availability of roads, waterways and other forms of transport is a critical consideration in the evaluation of an investment destination. The Chinese administration has made significant investments in the transport infrastructure. In fact, popular investment destinations in China such as Beijing,

The Old Man and the Sea by Ernest Hemingway Essay Example for Free
The Old Man and the Sea by Ernest Hemingway Essay The Old Man and the Sea is a story, in my view, about man vs. the elements, individuality, and one mans obsession to dominate his world. For Ernest Hemingway far more than for most men, the specter of age was a terrible specter indeed, and the virtue of action upon which he had based his art in his life was the virtue of the young. This, I believe, pervaded the legendary figure of Ernest Hemingway as the youthful, virile adventurer, tempered with humility. Hemingway has been notably preoccupied with individualism as well as self-endurance and, in my view, no where is this more exemplified than in his novel The Old Man and the Sea. The Old Man and the Sea is basically a story about an old man who sets out in a small boat on what presumes to be a routine fishing expedition. Unexpectedly, he connected with a very large fish which precipitated a struggle which appeared interminable. The fish was a marlin, and the struggle resulted in the death and capture of this enormous fish. At that point, he secured the marlin and headed home. Unfortunately, along the way, he was besieged by sharks which he was unable to fight off. The time span in the novel The Old Man and the Sea is relatively short. The old mans name is Santiago, and he spends all of eighty-four days without catching a fish. After his first nibble from this great marlin, he struggles greatly to hang on to this fish even though every muscle in his body causes him the greatest pain à ¾ and the second night he nibbles on a small fish and sleeps for the first time, whereupon a furious jerk of the line awakens him. Its during the third day that the great marlin begins to circle the boat and, in almost no time, the sharks (beginning with a mako) begin to move in on Santiagos catch. Even after Santiago brings in the bare remains of the flesh-stripped marlin, it creates a big stir among the village fisherman, and tourists observe with detached amusement the skeletal remains of Santiagos three-day battle. They do not understand the nature or significance of Santiagos experiences. Hemingway refers to the fishing rod being part of a life-death cycle. While the rod is alone without a fish on the other end, it is dead. However, when there is a fish on the end of the line, the rod becomes a living rod. This life ends, however, when the fish is removed from the line. The struggle for life is aptly presented in this story by Hemingway through describing the struggle of a fish and a man in which the fish struggles to free himself, while the man struggles to maintain him. It is a huge fish and he puts up a great fight. Two Hearted River: Part II à ¾ Summary and Analysis. Another story regarding life and death and the struggle for life was Ernest Hemingways short story Two Hearted River: Part II. he warmth and life-giving quality of the sun is mentioned early in the story. In the morning, it is as if the grasshoppers are lifeless. It takes the warmth and life-giving quality of the sun to spring these creatures to life. One grasshopper slowly works its way out of the b ottle Nick was holding. It seemed that temporarily this grasshopper had found life. However, as it jumped into the stream, its life was over as a trout ate the small animal and killed it. Another grasshopper was taken from the bottle. It was alive and squirming in Nicks hand. Nick then took a hook and thrust it into the thorax and the abdomen of the creature, killing it. Thus, life occurs one moment and death takes over the next. Another struggle is identified by Hemingway in this story. A living trout is hooked by Nick once more. The trout puts up a desperate struggle to free himself from the hook in his mouth. However, the struggle is lost and Nick hauls in the fish. Although he is allowed to live temporarily in a small sack that is filled with water, the fate of this fish is obvious. Nick holds the fish and whacks him against a log. The life in the fish ceases. The wriggling of the body stops as he turns rigid and lifeless. The death of a tree is also mentioned in this story. A huge, living elm had been uprooted by the force of the river, and it was not dead and lifeless. The aforementioned, Two Hearted River: Part II, is a minor work by E. Hemingway. At the same time, I chose this particular story because I felt it had particular significance for the primary subject of this research paper. Published Criticism At this point, I should like to proffer some criticism of Ernest Hemingway à ¾ and at the same time attempt to relate this to the primary topic of choice, i.e. The Old Man and the Sea. Whether Hemingway every achieved an ultimate solution to the dilemma of his approach to age, virtue and boyishness is not for us to judge, although the circumstances of his death indicated that he could not and would not abide a final weakening of those powers which were so important to the protagonists of his stories. In the last decade or so of his life, however, Hemingway did find a way to cope with the fact of his own age. He would dramatize what he could not avoid. Because of his absolute youthfulness, he regards old age as an utter and complete tragedy, as it is of course the only true tragedy, and he is not going to degrade himself by maturing or anything absurd of that sort. All the same, since he has a sense of costume, he will emphasize his decline in all its hopelessness by sprouting a white beard and generally acting the part of Senex. To a large extent, I believe that this critique has to do with the old man who has to give up on catching this fish. Similarly, in my mind , there is strong metaphysical evidence in terms of the old man and his refusal to give up on a struggle which he personally acknowledges is particularly difficult due to his old age à ¾ but yet he refuses to capitulate to this inevitability. Why is it that Ernest Hemingway pursues such thematic material with such drive and vigor? I believe that the answer may be found within the man himself. It has been acknowledged by critics à ¾ almost unanimously à ¾ that much of his thematic material reflects the man himself as, in my view, do his novels and short stories, as already indicated. To this extent, I should like to offer some biography on Ernest Hemingway which may serve to illuminate this belief. Hemingway was the second of six children of Clarence and Grace Hemingway. Upon graduation from Oak Park High School in 1917, he chose journalism instead of college, and spent seven educational months as a cub reporter for the Kansas City Star. Hemingway secured a part-time job as a feature writer for the Toronto Star and, in the fall of 1920, he became contributing editor of a trade journal in Chicago wherein he met one, Hadley Richardson, whom he married in September of 1921. Together they sailed for France and, for nineteen months occupied a walk-up flat in the Latin quarter of Paris. Hemingways serious writings began tentatively with the Paris publication in 1923-24 of two slender books of pros and poetry, yet his name was still little known in the U.S. Subsequently, he divorced Hadley and moved to Key West, Florida in 1928. He remained there for twelve years and completed A Farewell to Arms. There is much to be said about this man, and his experiences in Spain represented an entire chapter unto themselves. In Cuba in 1945, Hemingway began a romantic novel of reminiscences, including The Garden of Eden which, to date, to my knowledge, remains unpublished. Considering Hemingways passion for the sea à ¾ where he spent much of his life à ¾ and fishing, the thematic content of The Old Man and the Sea, to me, underscores the thematic content of individualism, struggle against the elements, and the refusal to bend to the challenges of time and old age.

The Roles of WWI and WWII in International Politics Essay -- History W
Throughout the field of international politics, many things forward the change of thinking and many cause futile argument and heated debate amongst international relations theorists and politicians alike, but none do this more than the subject of war. War has long been on the minds of the greatest thinkers the world has known, from Aristotleââ¬â¢s ââ¬Å"A Treatise on Governmentâ⬠(322BC) through, Machiavelli, Da Vinci to more recent thinkers and philosophers of our time. Theories have clashed violently over the subject and no other wars have had such a significant impact as World War I or World War II. They have become staple points for debate, and the basisââ¬â¢ of theories themselves, not just for war, but for the eventualities of other world-changing factors. The question of which war has had more impact on thinking about International Politics has puzzled intellectuals since the Second World War commenced. Not like many would think, at the end of World War II, simply the advent and prospect of another ââ¬ËGreat Warââ¬â¢Ã¢â¬â¢ immediately changed opinion. Realists sat smugly back as Liberal Internationalists ideals were thrown out. The questions began. How has the start of this war altered our previous ideals? How will it change world opinion? How on earth are we going to win another war? And the questions never stop, to this day, we evidently are still discussing the outcomes and impact of each World War, and of their collective impact. Unlike many of the great debates throughout International Politics, there is no ââ¬Ëgeneral consensusââ¬â¢ to subscribe to on this subject of thought.

Dress Code Essay Essay
In some high schools dress codes are being suggested. Parents and teachers believe that changing the dress code could possibly improve the learning environments in the school. In contrast, dress codes should not be changed because parents have the responsibility to supervise what their children wear, the students will lose their individuality but not their behavior in any way, and finally the school staff should be strict to begin with. Before parents start to ask for a change in other childrenââ¬â¢s wardrobe, they should first check what their child is wearing. This issue all begins at home and if the parent doesnââ¬â¢t see it then they shouldnââ¬â¢t be asking some other kid to change the way he/she dresses. As long as every parent enforced what their child wore, there would be no problem at school and the rules would be fine. Not every parent will do it, but for those who do care they should start to get rid of the inappropriate clothes that belong to their children. If the parents would be responsible enough to see and limit what their child wore, there would be no need for a change in the dress code in the first place. Enforcing a dress code would take away individuality but not change behavior. There are various ââ¬Å"clicksâ⬠around a campus and that is what makes it diverse. Changing the dress code would discourage creativity and aesthetic values in students. People desperately try to stand out from the crowd and these rules restrict oneââ¬â¢s fashionable rights. As a result, students just wonââ¬â¢t change behavior and all of a sudden become thirsty for knowledge, the students will remain the same. There is no point in changing the dress code because it wonââ¬â¢t work nor improve behavior in classrooms. The dress code would only limit individuality not personality. The dress code should be enforced not changed. Instead of telling students to buy similar outfits, which some cannot, the staff should be more stricter in dress code policies. For example, in my school teachers and staff are complaining about how girls dress. However, I have never seen them actually punish them or warn them to not do it again. If schools were to enforce the rules they come up with everyone would know not to rebel against them. The students would keep in mind that they might be punished for doing something that is against the rules. When staff begins to reinforce their rules a decrease in rule breaking will occur. Therefore, changing the strictness of the rules will bring about a better environment not a change in dress code. There is no need for a new dress code. Knowing that the parents and teachers could first change the ways they do things could help eliminate the thought of changing the dress code. Parents should limit what their children wear to respect the dress code already in effect. This will let the rest of the student body express themselves liberally and not have to give up their creativity and fashion sense. Staff should begin to enforce the rules to create the positive environment they want. Changing the dress code is the wrong alternative for an increase in academic potential.

Racial profiling Essay
Imagine driving home from school to go put on your uniform to go to work. You are driving the posted speed limit, obeying all traffic laws, and you car is in perfect working condition. All of a sudden, flashing red and blue lights behind you and youââ¬â¢re being pulled over. The officer treats you as a suspect right off the bat, smothering you with questions concerning what youââ¬â¢re doing, where youââ¬â¢re going; yet never really telling you why youââ¬â¢ve been pulled over. Without any warranted reason the officer wants to search your car. After much hassle you are finally free to go, yet still have no explanation as to why you were pulled over to begin with. Well that happened to me one year ago after being pulled over three hours earlier. Later on i learned that there were a Mercedes Benz that was stolen in the neighborhood, and i was a black women driving a Mercedes Benz fitting the description of the one that were being stolen. But there were other Mercedes car in t he street that day. Why didnââ¬â¢t he stooped them. Guess what the officer was a white man, this prove that i was subject to racial profiling. Still today many people donââ¬â¢t know the definition of racial profiling. What does it means? According to Kenneth Jost, author of the ââ¬Å"racial profiling ;Are minority unfairly targeted by policeâ⬠stated that Racial Profiling is any police or private security practice in which a person is treated as a suspect because of his or her race, ethnicity, nationality or religion. This occurs when police investigate, stop, frisk, search or use force against a person based on such characteristics instead of evidence of a personââ¬â¢s criminal behavior. It often involves the stopping and searching of people of color for traffic violations, known as ââ¬Å"DWBâ⬠or ââ¬Å"driving while black or brown.â⬠Is racial profiling helps or huts community/America? In my opinion i think that racial profiling is a detriment to our soc iety, because it is a form of discrimination, it is unconstitutional, and its violates humans right. Should there be something done to stop this growing madness? Racial Discrimination is a serious problem in the world today. Race remains a significant social issue because people use racial differences as the basis for discrimination. Racism is a clear reality in our society, and it is continues to shatter and destroy lives. Racial discrimination is anà ongoing human judgment that U.S. citizens canââ¬â¢t really stop. Letââ¬â¢s take a look at one example on how racism is a problem ââ¬Å"New York City college student Trayon Christian, 19, filed a civil rights suit against Barneys after he was stopped, handcuffed and taken to a police station after buying a $349 belt at the upscale department store.â⬠Why did that happen ,well because he was black. The life chances and opportunities of people of color in the United States are limited as compared to whites. The legacy of historic discrimination continues to weigh on the present; and current day discrimination persists throughout American life in access to healthcare, educational serv ices, employment opportunities, wage levels, capital, the criminal justice system, and media employment. Racism, is difference plus power. All forms of racism suppose,on Paul Bou-Habibââ¬â¢s conception,author of theâ⬠Racial profiling and background injusticeâ⬠say that ââ¬Å"the differences between races mean that they cannot coexist in one society on terms of equality. This information is important because it allows us to further understand the history of racial discrimination. In the United States Bill of Rights, the Fourth Amendment is ââ¬Å"the right of the people to be secure in their houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized,â⬠(qtd.in Saeed). Racial profiling is a clear violation of the bills of rights in the United States citizens. New measures must be taken in conjunction with current measures to curb racial profiling. A strict federal program to monitor and survey our nationââ¬â¢s police officers is needed. The public also needs to become more involved in efforts to stop racial profiling. Until these measures are taken, racial profiling will continue to eat away at the heart of our nation. Being frisked, arrested, or incarcerated is often a humiliating and degrading process in violates human rights. Many police officers have also been known to abuse their authority. Take for instance. In 2009, police in Detroit, Michigan, conducted a stop and- frisk of Elvis Ware. While in a public parking lot, one officer shoved his bare hand down Wareââ¬â¢s pants andà squeezed his genitals and then attempted to stick a bare finger into Wareââ¬â¢s anus. Other young men of African descent report that the same two officers who stopped Ware conducted similar outrageous and inappropriate searches on them without warrants, probable cause, or reasonable suspicion.ââ¬â¢ Such ââ¬Å"encounters can result in negative behavioral changesâ⬠(Jost). Minorities, even those who are innocent, may feel pressured to dress in a particular way to avoid drawing attention to themselves, or to stop traveling certain routes in order to avoid interacting with the police. Additionally, exposure to racial profiling may be psychological detrimental, possibly resulting in lowered self-confidence and dignity. Based on these, as well as others, it can be effectively argued that racial profiling is not, in and of itself, an unethical practice. However, it must be used in a precise manner in order to be morally sound. This method includes using it as a tool in the investigative process and not before it has been determined that a crime has been committed. It must also be used in a specific way: to describe an individual suspect and not a group of people who are suspected of possibly committing one crime or another. The witnessââ¬â¢s background and bias must be taken into account, and racial profiling must be done equally and without favor to one racial group. After these steps are taken into account, racial profiling cannot be considered ââ¬Å"unethicalâ⬠(Saeed).

Passive vs. Active Voice
Passive vs. Active Voice Passive vs. Active Voice Passive vs. Active Voice By Erin English teachers like myself love to warn new writers against the evils of passive voice. Here at Daily Writing Tips, Michael has written about passive writing, and I recently wrote about dummy subjects, but it looks like theres still some confusion about passive voice and its use. For more on passive vs. active sentence construction, I turn to two books that should be staples in any writers library: William Zinssers On Writing Well, and Constance Hales Sin and Syntax. First, lets review what passive voice is. In most sentences, we have a subject performing an action. For example: Jason threw the ball. Jason is the subject. In a passive sentence, the subject of the sentence is acted upon rather than performing the action, as in: The ball was thrown by Jason. The ball is the subject and it is being acted upon. Verbs in the passive voice have two parts: some form of the verb to be and a past participle form of the action verb: was thrown. (The helping verbs has or have can also appear in a passive verb: the ball has been thrown.) A writer may choose to use the passive voice in order to emphasize one thing over another. In the second example, the ball (rather than Jason) becomes the most important component of the sentence. Zinsser says that passive voice should be used sparinglyonly when theres no way around it. The difference between an active-verb style and a passive-verb stylein clarity and vigoris the difference between life and death for a writer. In most (but not all) cases, the passive construction is longer, clunkier, and more vague. Take these examples from student research papers: The poorer people were deprived of their opportunities. Documents were cited to prove that an estimated 12 to 20 million illegal immigrants have been admitted to the United States. Talks have been conducted on the subject of starting a worker program for the illegal immigrants. In each of these examples, the passive voice construction gives us unnecessary words and clunky sentences that can be easily revised: Harsh immigration laws deprive poorer people of opportunities. State Department officials estimate the number of illegal immigrants at from 12 to 20 million. President Bush has proposed starting a [guest] worker program for the illegal immigrants. In part, the use of active voice over passive voice is a matter of word economy and simplicity. If you can say something with fewer words, you probably should. Its also a matter of making your words work for you. As Zinsser says, active verbs push hard and passive verbs tug fitfully. Using an active verb helps make the sentence more vivid and precise; does your subject walk, or does he saunter? Does she fall, or does she stumble? Hale warns against relying too heavily on is and are (and to be in all its forms): Novices tend to rely on is and other static verbs and lose momentum by stumbling into the passive voice. That said, you still have to be careful not to overdo it. Sometimes, passive voice is useful. Sometimes its even necessary. As commenter Bill G pointed out, the dummy subject it is necessary in describing weather phenomenon (it is raining). In Sin and Syntax, Hale gives us this example: Writers and editors can get too literal-minded about eschewing the stationary passive. They forget that the passive voice does exist for a reason. One syntactically challenged slot editor at the Oakland Tribune, sticking adamantly to a policy demanding the active voice, changed the screaming, above-the-fold headline I-580 killer convicted to Jury convicts I-580 killer (which screamed less loudly, since the stretched-out phrase required a smaller type). In Hales headline example, we can see that the sentence was better served by the passive construction. The action (the killers conviction) was more important than the subject of the sentence (the jury). The trick is knowing when to use active voice, and when passive voice is more effective. Many writersespecially beginnersrely too heavily on passive construction, allowing their prose to become limp and lazy. You can keep from falling into this trap by being conscious of your use of dummy subjects (it and there) and be verbs. Want to improve your English in five minutes a day?

Physics-Inclined Plane Lab Essays
Physics-Inclined Plane Lab Essays Physics-Inclined Plane Lab Paper Physics-Inclined Plane Lab Paper If an object is placed upon a surface that is inclined at a certain angle then that will decide the acceleration in which the object is going down the inclined plane. When looking at an inclined plane it is important to see what forces are acting upon it to see what the object is doing. In our case of there was Fn, Gravitational Force and, Fd. These forces act upon the object to see where it is going. In an inclined plane there will always be at least two forces acting upon the object which would be weight (pointing downwards) and force normal (pointing forwards). Force normal as always been the opposite of the gravitational force, but that is not true because we now of horizontal planes, but this is a inclined plane and the truth is that Force Normal is always perpendicular to the surface the object is on. ength of Ramp: The length of the ramp was always constant as it was 100 cm. The length of the ramp never changed as the car always began accelerating for a total distance of 100 cm Distance of Motion Detector from Ramp: The distance of the motion detector and the ramp was about 40 cm. With there being 40 cm between the motion detector and the ramp the data that we collected could be extremely precise. The data would be precise and our acceleration would pin point. The only problem we had at the start was that it took time to set the motion detector to detect the car until we found the perfect place for the ramp to perceive the data. Coefficient of Friction: The coefficient of friction was taken away because of the equipment that we used. For example we had the frictionless car that helped reduce the friction greatly; also the ramp let the wheels fit into the plane which made the friction almost definitely According to our graph above which is the points we got from our lab; we can say that as the angle of inclination increases then the average acceleration would increase. Except for a few exceptions its is proved through our graph that the acceleration is increased as the angle is increased, but for those exceptions we may be able to say that error was involved as 30% is quite high. We found our data using two different methods and different numbers for each and generally got different answers. By looking at all of our data we can come to the conclusion that the angle of inclination does not affect the acceleration. Like our Projectile Motion lab that we have done recently the projectile went a certain distance at a certain angle and then after changing the angle the distance would decrease after a while. We can say the same for this Lab as that when the angle is lower than 90 the acceleration would increase until the angle is above 90 and the acceleration will decrease again. This is because if one looks at this problem it makes sense. The car will go much faster until the ramp if perpendicular to the ground and when you lower the ramp to 180i then the car will barely have any acceleration considering there is no friction. In our Lab we can calculate that there is about 32% error which is very high, but for several reasons is true. I believe that this 32% error was taken because of random and systemic errors meaning that what we did made the error much higher than it should be and also the fact that the instrument was a bit hard to work with. One random error was that we definitely did not collect data and that if we did collect more data the results would be much more precise then they are. Another Random Error was the time that we used, we may have not used the time to our best accomplishment as it took much time to prepare and also take all the data down. A Systemic error that occurred was with the frictionless car as the motion detector took a lot of time to detect the car and we had to measure at which height the car would be detected. This took several pre trails of which none were counted. Our results from which we got from the lab compared to the gsin? results were not that much different, however there were certain points that did not match up. From my overall look I can say that the design and method of the investigation was good. There were few weaknesses in the lab, such as the motion detector taking time to set up as well as getting it to work properly which may have increased the error. Another weakness was our time management which was not up to par, where in this case we were at times working to fast and rushing a lot as we didnt have much time left which affected our data greatly. Another weakness was when averaging the acceleration we only had constant acceleration for about 1 second in which we averaged those numbers together. The precision of the data was decent as our motion detector was quite accurate. For the few weaknesses I had I can say there are simple solutions for them to be avoided next time. With the motion detector I think we could first find a proper height for both the ramp and the car to be placed at and whenever we raised the ramp we would raise the motion detector by the same amount. Next was the time management where as always we could have stopped rushing and taken our time even though it was scarce, this was because we had to do this lab during a time with constraints. The last weakness was with the acceleration and my solution is to increase the length of the ramp and let the car run for more time and thus we will get a more detailed acceleration. To remove systemic/ random error next time we would have to make sure we have more time for the experiment and set up properly.
