No Longer at Ease Essay

One of Chinua Achebe’s main socio-political criticisms in No Longer At Easeis that of corruption in Nigeria. From the moment the book begins the main character, Obi Okonkwo, is confronted with the issue of bribery. From the moment he arrives at customs to the point at where he gives in to taking bribes himself, the voice of Achebe lingers in the backdrop through the words. At first Obi is as critical as Achebe of bribery. He refuses to take bribes and also finds it necessary for himself to be a â€Å"pioneer† in Nigeria, bringing down corruption in government and instigating change. It seems that corruption runs rampant and that everyone in Nigeria from the â€Å"white man† to the Umuofian Progressive Union participates in â€Å"seeing† people about what they need done. Men offer money, and women offer their bodies, in return for favors and services. Obi believes that by not taking brwhile at the university in London, a paper in which he theorized on what would change the corruption of high positions in Nigeria. He believed that the â€Å"old Africans† at the top of civil service positions would have to be replaced by a younger generation of idealistic and educated university graduates, such as himself. Achebe, however, is not as optimistic as Obi because he has Obi fail. Achebe takes us through the path of how someone like Obi can come to take bribes. The book begins on a negative note: starting with Obi’s trial. It is as if Achebe, by beginning in the end, is saying that Obi was doomed from the start. Obi’s position is a difficult one. He is born in Ibo, but he has been educated in England and often feels himself a stranger in his own country. He has lost his love because of a rule of the past, he has suffered under great financial distress, he has exerted himself because of the expectations others have placed on him, and he has lost his mother. All of this brings the protagonist of the novel to fall into what he once had believed was a terrible and corrupt act. Still, Obi always feels guilt at taking a bribe, and he had decided to stop ibes he can make a difference. He had written, them. By having Obi get caught, even amid an aura of repentance  and guilt, Achebe further illustrates the hypocrisy of all who have participated in bribes and now throw stones at Obi. And, at the same time, it tells us that, although he got caught, Obi is still a pioneer because he has sworn to not do it again. It may be that his beginning as a â€Å"pioneer† is a rough one, one that has taken a curved path, but it does not definitely mean that he cannot still lead toward change. Still, perhaps Achebe may be saying that this is not true, and that Obi, ultimately, has failed at the task he set before himself. Whether the book is a tragedy (an unresolved situation) in Obi’s definition of the word or not is up to whether we believe that it is Achebe who is the greatest â€Å"pioneer† in the novel. In other words, it is the author’s critical voice that will lead others out of such corruption, if not by only making the world and younger generations of Nigerians aware of it. The Influence of Education One of the most important aspects of Obi’s life is that he was educated in England. This small fact molds the way others treat him and shapes what others expect of him. At the same time, the education he holds dear is also one for which he has felt guilt and one which has often made him a stranger in his own Nigeria. Upon his return from England, Obi is secured a position in the civil service, given a car, money, and respect. At the same time, however, he seems to be making constant mistakes because of what he has learned to be like, what he has come to understand, and what he has never learned. For instance, when Obi first arrives, he is given a reception by the Umuofian Progressive Union at which he makes several mistakes. He has forgotten how to act in his home or simply does not agree with its ways: he wears a short-sleeved shirt and sees nothing wrong with it, for it is hot, and he speaks casually in English, instead of the kind of heavy English that the Umuofians admire in the president of the Union. His education has brought him status and has placed him in a position where others expect the most and best of him. No one can understand, in the end, how a man of â€Å"his education and promise† could take a bribe. Of course, Achebe, says this cheekily since many who have accused him and who also hold high positions are guilty of similar transgressions. Ironically, the only thing his â€Å"education† did not teach him was how not to get caught. Another important aspect of education, aside from the contradictions mentioned above, is the  fact that Obi’s generation uses its education as a tool, paradoxically, against colonialism. Sam Okoli, the Minister of State and also an educated man, verbalizes the position of the populace by saying that, yes, the white man has brought many things to Africa, but it is time for the white man to go. In other words, a man like Obi can use his education to take his country back into his own hands, even if his education is something that the colonizer gave him. It is important to remember that the only way to survive in a world where two cultures have met is to allow a certain amount of mixture to be used in a positive regard. Tradition versus Progression While Obi is in England he misses his home, longs for his family, and writes nostalgic poetry about Lagos and the sun and the trees of his homeland. He even begins to feel a certain degree of guilt, at times, for studying English and not being in Nigeria with other Ibo people. Nevertheless, this â€Å"English† has become a part of him, one that he cannot erase when he arrives back in Nigeria. Obi is in love with his native tongue, and it holds a place in his heart. At the same time, however, he is also comfortable with the English language. The struggle of language is just one of the many examples of how African tradition and English culture collide in this novel. Obi loves his family dearly, and since his family is symbolic of his roots, it can be said that he loves his roots dearly. This is not to say, however, that he will not rebel against his roots because of things he has learned elsewhere. Obi possesses the more liberal, and even â€Å"European,† belief that he may marry anyone he wishes, even though his family and his countrymen are opposed to it. And, even though he wishes to marry Clara in the end, despite her history, he is tied to his mother a symbolic traditional root †¦ his blood. It is this struggle between tradition and European ways that is evidenced throughout and that is further amplified by the European presence of characters like Mr. Green. And, aside from the obvious Mr. Green, there are also the more subtle presences of Europeans at lounges and restaurants throughout Nigeria serving English food and importing European beers. Some of these colonial importations and introductions are good, as is evidenced by the scene about the radiogram between Obi and the Minister of State. Nevertheless, the  struggle exists, and it is obvious that Achebe has a strong negative opinion about colonialism as a whole. Motifs Songs and Poetry Throughout the novel there are songs and poetry that mean different things at different moments in time. When Obi is away at school his poetry is a kind of pull toward Nigeria, a calling and remembrance of home and yet, he writes these poems in English. While he is in Nigeria, there are many songs sung in his presence, some of which Obi also dissects using the English language but not without the Ibo pulling at his heart. It is as though, however, all of this poetry and song represents his desire for home and his heart’s need for it. He has studied poetry in England, but poetry also links him to home—these poetic contradictions are all appropriate to the novel’s ultimate struggle, which is that of the young man living under the end of a long colonial reign. Proverbs If allusions to English literature are what are constantly driving us toward England, it is the constant allusion to proverbs that drives us back to Africa. Achebe peppers his novel with proverb after proverb, making the novel specifically and strategically African. Achebe, like Obi, is using the tools of colonialism for his own purposes; he is making the European form of the novel his own. Language The issue of language is omnipresent in the novel and is simply one of the many issues that arise out of a colonial society. Obi struggles between two tongues (Ibo and English) just as he does between two cultures. He was born into one language, and he obtained â€Å"knowledge† in the form of the other causing one of the basic problems throughout No Longer At Ease. Symbols Mr. Green Mr. Green is symbolic of the European presence in Nigeria, as he is the epitome of the â€Å"paternal colonizer,† who has brought some good but mostly arrogance. He is very much the kind of Englishman who believes in the good of empires and thinks he can, as Obi points out, tell people how to live their lives. The Umuofian Progressive Union If Mr. Green stands for Europe in Obi’s struggle between tradition and European ways, then the UPU stands for the stubborn traditional ways of the past. Mr. Omo  Omo stands for what Obi calls the â€Å"old African,† which is representative of a more submissive, (to the British) older generation of Nigerian. It is a generation that has more â€Å"fear† of the British than the younger generation, which longs for independence and freedom. ————————————————- Analysis of Major Characters Obi Okonkwo The protagonist of the No Longer at Ease, Obi Okonkwo, is a young man born in Ibo in the Eastern Nigerian village of Umuofia. He was well educated and eventually sent to study law in England, a course of study he eventually changed to English. He stays in England for nearly four years, at times longing for the warm weather of home and all the other nostalgic qualities his memory supplies him during long winters abroad. Nevertheless, his arrival is less than what he has expected. Because he is educated, he is given a â€Å"European post,† and he works in an office whose ethics he finds repulsive. He stands firmly against the bribery that goes on and is opposed to his boss, a very old, white, and English colonial man named Mr. Green. Obi finds himself in a constant battle between traditions of the world into which he was born (that of the village and his traditional African roots), represented by the Umuofian Progressive Union, and the conventions of a changing world. Obi finds himself at the beginning of a generation of change, caught between two worlds. He is unable to marry the woman that he loves because she is considered an outcast. He claims to want to marry her anyway because by the time he has children, the world will have changed, and it will not matter, just as it does not matter now that his father is a convert to Christianity (a conversion that was once quite scandalous). Still, Obi loses his fiancà ©e, his mother, and finds himself in serious debt throughout the course of the novel. He must pay back his scholarship loan and is responsible for sending money home. Eventually, Obi breaks under all of this pressure and gives in to the bribery he had stood against so  idealistically, but he does not give in without guilt. At the end, he even claims to be finished with bribery, right before he is caught. Somehow it is too late, and his situation, his position of being caught between two shifting worlds, becomes almost impossible. Obi’s birth name is Obiajulu which means â€Å"the mind at last is at rest,† and this naming is a looming irony, considering the title of the novel and Obi’s predicament. Obi is ill at ease in both of his cultural experiences—he lies in the middle, a difficult place. Clara Clara is another character in the novel that is struggling in the changing world of pre-independence Nigeria. She is educated abroad, like Obi, and has a career as a nurse. She has a mind of her own and is often stubborn but shows herself to be quite caring, nevertheless. The first one-on-one conversation she has with Obi was regarding Obi’s seasickness (she had gone to his cabin, on their voyage home, because she had seen that he was feeling ill). She is also willing to compromise, and, although she finds Obi’s poetry boring, she is willing to listen to it. She is also willing to meet with friends of Obi’s that she dislikes. While she seems quite spoiled at times, she does her shopping in the slums and is willing to genuinely give Obi money to save him from trouble, even if he is unwilling to take it. However, the truth remains that she is a difficult person, perhaps because she finds it difficult to let go of her past. She is strong-minded though not intellectual and finds herself bound to a tradition that seems unfair to both her and Obi. She is burdened by the fact that she is an osu, which means that because of her ancestral past, she is an outcast. It is for this reason that she cannot marry the man she wishes to marry. Though Obi claims he does not care, he respects the ultimatum of his mother, which is that he must wait until she is dead, or she will kill herself if he marries Clara while she (his mother) is alive. This upsets Clara, and it is after this that they have their final break-up, after which Clara is hospitalized because of complications during an abortion. During this time Clara refuses to see Obi. From the beginning Clara’s romance with Obi was on unstable ground. Symbolically we need only to look at where Clara and Obi first began their relationship: in the water, on turbulent and fluctuating grounds. William Green The character of Mr. Green is representative of the white, European presence in Africa that resulted from the spread of England’s empire and its colonial hold on Nigeria. He is an arrogant man, who believes that the African is â€Å"corrupt through and through† and that it is the British who have brought Africans civilization and education. Nevertheless, Mr. Green seems to be committed to Nigeria, and there are characters in the book such as his secretary, Miss Tomlinson, who constantly support him in spite of his â€Å"strangeness.† Miss Tomlinson, however, is also a white Englishperson living in Nigeria. The narrator tells the reader that Green works long and hard hours, but this â€Å"quality† is constantly being uprooted by reminders of his colonial attitude and superiority complex. He thus has a problematic relationship with Obi, who is an educated African in a European post. Still he believes in education, which makes it both ironic and fitting that he pays for the education of his steward’s sons. Mr. Green finds it a problem that Africans ask for weeks off at a time for Mr. Green finds it a problem that Africans ask for weeks off at a time for vacations. However, this tradition was actually started by the very Europeans who held these high posts in civil service prior to the Africans themselves. These contradictions are constantly arising out of the character of Mr. Green. He is an archetypal figure of patriarchic colonialism that finds it difficult to relinquish such a position. In fact, when he thought Nigerians would attain independence, he had threatened to resign. Significantly, Mr. Green is a figure of an older world that is constantly present in the Nigeria of the late fifties, which Achebe portrays, only several years before its eventual independence, when a figure like Green will remain a problem but eventually become obsolete. ————————————————- Plot Overview Obi Okonkwo is a young man, about twenty-six years old, who returns to Nigeria after studying in England at a university for four years. No Longer At Ease, begins with a trial against Obi that takes place a while after his return, and the novel then works its way backward to explain how Obi has come to be charged with accepting a bribe. The Umuofia Progressive Union  (U.P.U) has given Obi a scholarship to study law in England, a scholarship that Obi has to pay back upon his return. And, thus, he leaves for England, stopping in Lagos on the way out. While in England, several things happen to him. First, he changes his course of study to English and abandons law. Secondly, he finds himself nostalgic for home, writing poems about Nigeria. Finally, he meets a girl named Clara at a dance in London but fails to make a good impression. However, the girl is Nigerian also, and on Obi’s boat ride back home, after nearly four years in England, he meets Clara once again. This time, they begin a relationship. Once back in Nigeria, Obi stays, once again, in Lagos with his friend Joseph, trying to find a job and a place of his own. He also visits his own home village of Umuofia. Obi is quickly given a post on the Scholarship Board of the Civil Service and is also quickly introduced to the world of bribery, which is a world he wholeheartedly rejects with a strong idealism at first. This is indicated early on when a man offers Obi money in order for Obi to â€Å"pull strings† for his little sister’s scholarship. Obi is appalled and rejects the offer, only later to be met at home by the little sister herself who offers Obi her body in return for the scholarship favor. Again, Obi rejects this offer. Although Obi begins his life in Nigeria in an honest way, events do not go as he has planned. First, Clara tells him that she cannot marry him because she is an osu, an outcast. Obi decides to ignore this and go against what most of his fellow countrymen believe to be a major transgression of custom, and he decides he will marry her anyway. Still, his economic hardship worsens, given that he has to send money home and that he is in debt. Obi then receives a letter from his father telling him that he must go home. When he arrives at home he sees that his mother is very ill. And, his parents tell him he must not marry Clara because she is an osu. In fact, Obi’s dying mother gives him an ultimatum: she tells him that if he insists on marrying Clara, he must wait until she is dead because if he marries Clara while she is alive, she will kill herself. Obi, therefore returns back to Lagos and tells Clara all that has transpired. Clara becomes angry and breaks off the engagement, afterwards hinting at the fact that she is pregnant. It is at this point when Obi arranges an abo rtion. He does not have the money and needs to borrow it. Complications arise out of the operation, and Clara is hospitalized, after which she refuses to see Obi. Obi then returns to work,  only to be notified that his mother has died. He does not go home for the funeral, and the U.P.U. discusses this failure on Obi’s behalf as a sign of his not having cared about his mother’s death. The truth, however, is that he was terribly saddened by her death, feels terrible remorse and guilt, and has entered into a state of mental unrest. However, Obi awakes from this unrest with a new sense of calm. He feels like a new man, and it is at this point that he takes his first bribe, not without a certain degree of guilt. Obi allows this acceptance of bribes to become habitual. He continues to take bribes until the end of the novel, when Obi decides he cannot stand it anymore. He has paid off all of his debts and can no longer be a part of the corruption. It is at this moment, however, when he has taken his last bribe, that he is caught, which brings us back to the beginning of the novel. Discuss the Significance of the novel’s title: No Longer at Ease. Answer for Study Question 1 >> The title of the novel relates mostly to Obi and his predicament. He finds that he is â€Å"no longer at ease† inside African society, where bribes are taken, where he is shunned for wanting to marry the woman he loves because of his ancestry, and where he is looked down upon because he has trouble relating the people from the village where he was born. He is not â€Å"at ease,† either, however, within British sectors of society. He is able to speak fluent and good English, he is able to analyze and discuss, but he is unable to relate to someone like Mr. Green. He also feels himself, like other Nigerians, as is evidenced in the retrospective scene about London, a stranger in a strange land while in England. He misses Nigeria and is in fact nostalgic for her when he is away. He understands what he must do for his country and that she is important; however, his return is different from memory. Memory is, in many ways, shattered when he revisits Lagos and his old home of Umuofia. Furthermore, by the end he finds himself uneasy with his lot in life: he is broke, he has lost Clara and his mother and has given in to taking bribes. Finally he feels guilt for this but it is too late. There is also the irony of Obi’s name, which means â€Å"the mind is at last at rest.† It is supposed to mean that his father’s mind is at rest because he was born a boy after so many girls; however, when juxtaposed against the title of the novel it becomes the greatest irony of the novel because Obi  is, of course, never, himself, â€Å"at rest.† The title is perfect because it describes a generation of Africans, in this case Nigerians, that find themselves living in between worlds, cultures, and on the verge of a post-colonial world. Close Discuss the problem of language in the novel. Think about the problem as it relates to the characters of the novel as well as to Chinua Achebe. Answer for Study Question 2 >>  Language is an issue that arises out of all colonized countries because the colonized are educated in the â€Å"language† of the colonized. The issue arises time and again in Achebe’s novel. When Obi returns from England, the members of the Umuofian Progressive Union are not impressed by Obi’s English because it is too casual. They like to listen to English when it is full and spoken in all its purple prose, in the way that the president of the UPU speaks it. This kind of English is a kind of class token. There is a certain amount of pride, ironically, in the language of the colonizer. This may be, however, because those admiring this English are from an older generation. When Obi is discussing eating yams with his hands he says that the younger generation can do this because they do not fear being called â€Å"uncivilized†Ã¢â‚¬â€the same may apply to their mode of feeling regarding language. The younger generation of Obi and Christopher, Obi’s friend, plays with language much more easily. For instance Christopher speaks different kinds of English, depending on what he is talking about and to whom he talking. Obi claims that most educated Africans participate in this playfulness with language. Obi has his own problems with language as is evidenced when he attempts to speak or read for his family in his own language and finds it difficult. His mother tongue, although never replaced sentimentally, is often replaced by an English that comes with more â€Å"ease. He is able to translate into English and understand. Nevertheless, Ibo is still a special language—the language of home. It is the language that Clara speaks to him when they are alone for the first time, and it is the language he longs for while he is across the sea in England. Close What are the main reasons for Obi’s change of opinion toward bribery? Answer for Study Question 3 >> First of all, Obi never really believes that it is all right to take a bribe, he always seems to do so with a sense of guilt. Nevertheless, there may have been moments where it was simply a fall into complacency or even an act that arose out of the aftermath of desperation. Obi’s financial situation was poor, he owed money to many people, he had his scholarship to pay back, he had to take care of himself, and he had to send money home. The temptation to take a bribe was always present. However, what seemed to put him over the edge was not his financial burden but his loss of hope. He had lost his mother and his lover, plus he found himself constantly out of place and ill at ease. He longed for complacency and contentment—for the kind of attitude that Christopher, an educated friend much like himself, was able to take on. Perhaps he even took the bribes to illustrate that he knew the way things worked that he, too, even if he had gone away for four years, knew how the ways of the Civil Service functioned. Still, this bribery was never something he was comfortable with but his feelings of unease only amplify by his guilt and his being caught.

Emotional Intelligence Essay

?When it comes to the five elements of Emotional Intelligence, I can relate to Self-Regulation the most which is my best aspect. In general, I am a pretty easy going type of guy. Even when someone bad mouths me or attacks me verbally, I tend to keep my cool and analyze the situation before responding back. When it comes to my job as a police officer and dealing with people, we deal with all types of emotions. Some personalities can be distressed, combative, and anxious or anger. Whatever the situation may be, I always tend to self regulate my emotions so that I can best deal with the situation. One example is during an interrogation, another officer and I will play the roles of God Cop Bad Cop, with me being the Good Cop. I am always the Good Cop because I can restrain myself when the suspect tends to be argumentative or angry. I tend to regulate my emotions and not respond in the same manner. The worst aspect of Emotional Intelligence for me would be Social Skills. This is something I am constantly struggling with. When it comes to conflicts, I tend to either avoid it or eliminated the easiest way to avoid more conflict. I know it is easier said than done, but with learning how to deal with can make me a better leader at earning respect and loyalty. I also tend to lack on praising others outwardly. For example, when I see a good arrest from a co-worker based on his observations skills, I know he did a good job and I praise him for it, but I usually don’t say it to him. Not because I do not want to but because I am not comfortable saying it outwardly. I know I can improve on praising others because it is important for your co-workers or subordinates to feel important and appreciated. It tends to bring the best out of them. When it comes to conflict resolution, I will work on reaching a solution through common techniques like negotiations or compromises.

Science ; Future

Much of what IVe said would seem uncontroversial or even platitudinous to the scientifically-attuned audiences here in Newcastle this week. But there's one thing that scientific advisors in any democratic system must not forget. When really big and long-term policies are in contention – whether about nuclear weapons, nuclear power, drug classification, or health risks – political decisions are seldom purely scientific: they involve ethics, economics and social policies as well.Such discussions hould engage all of us, as citizens – and of course our elected representatives. Sometimes this has happened, and constructively too. The dialogue with parliamentarians led, despite divergent ethical stances, to a generally-admired legal framework on embryos and stem cells – a contrast to what happened in the US. And Lisa Jardine has chaired the HFEA, another fine precedent. But we've had failures too: the GM crop debate was left too late – to a time when opin ion was already polarised between eco-campaigners on the one side and commercial interests on the other.Scientists have a special responsibility to engage – though they should accept that on the economic, social and ethical aspects of any policy they speak as citizens and not as experts. But despite many worthy efforts, there are habitual grumbles that such inputs don't have much traction with politicians. For them, the urgent trumps the important. The local trumps the global. And getting re-elected trumps almost everything. Anything that gets headlined in the media, or makes their postbag bulge, will get attention.It's volume not quality that counts. So scientists might have more leverage on politicians indirectly – by publicising their research and letting the media do the campaigning – rather than by more official and direct channels. This is one reason – over and above the general cultural value of our findings – why â€Å"outreach† by s cientists is important. And there are special things universities teachers can do. We're privileged to have influence over successive generations of students.We should try to sensitise them to the issues that will confront them in their careers – ndeed, polls show, unsurprisingly, that younger people who expect to survive most of the century, are more engaged and anxious about long-term issues. We fret too much about minor hazards of everyday life: improbable air crashes, carcinogens in food, low radiation doses, and so forth. But the wide public is in denial about two kinds of threats: those that we're causing collectively to the biosphere, and those that stem from the greater vulnerability of our interconnected world to error or terror induced by individuals or small groups.The issues impel us to plan internationally (for nstance, whether or not a pandemic gets global grip may hinge, for instance, on how quickly a Vietnamese poultry farmer can report any strange sickness). And many of them – energy and climate change, for instance, involve multi-decade timescales – plainly far outside the â€Å"comfort zone† of most politicians. One issue that should be addressed is whether nations need to give up more sovereignty to new organisations along the lines of IAEA, WHO, etc.Final message Unlike our 17th century forebears who I cited at the beginning of this talk, we know a reat deal about our world – and indeed about what lies beyond. Technologies that our ancestors couldn't nave conceived enrich our lives and our understanding. Many phenomena still make us fearful, but the advance of science spares us from irrational dread. We know that we are stewards of a precious â€Å"pale blue dot† in a vast cosmos – a planet with a future measured in billions of years, whose fate depends on humanitys collective actions. But all too often the focus is parochial and short term.We downplay what's happening even now in impoverish ed far-away countries. And we discount too heavily the problems we'll leave for our grandchildren. We can truly be techno-optimists. But the intractable politics and sociology – the gap between potentialities and what actually happens – engenders pessimism. We need a change in priorities and perspective – and soon – if we are to navigate the challenges of the 21st century: to share the benefits of globalisation, to prioritise clean energy, and sustainable agriculture; and to handle the Promethian challenge posed by ever more powerful technology.To survive this century, we'll need the idealistic and effective efforts of natural scientists, environmentalists, social scientists and humanists. They must be guided by the insights that 21st century science will offer, but inspired by values that science itself can't provide. And I give the last word to a great scientist who was himself once the president of the BA – the biologist Peter Medawar: The bells that toll for mankind are like the bells of Alpine cattle. They are attached to our own necks, and it must be our fault if they do not make a tuneful and melodious sound.

Plate Tectonics and Weathering and Erosion Essay

Plate Tectonics and Weathering and Erosion - Essay Example Some territories of our planet suffer from annual earthquakes constantly, but it does not mean that population of these regions has got used to such events.

Write a tight, spare story - Essay Example Henry was in his office when Alice, boss’s wife came into his room, she dressed to kill in a red tightly fitted dress. She stood there in front of his desk staring right into Henry’s eyes. Henry inhaled. He clearly knew what the woman was all after and the thought of it terrified him to his bones. He lit a cigarette to try and ease the tension that had started to build up. A chemical smolder build in his lungs, somewhat stinging the raw flesh of his body, through his throat to his nose making his eyes water. Exhaling into the dark room Alice was still there standing plotting on how to trick this man into her fantasy. After a while they chanted about all sorts of things and the relationship between them started to blossom gradually. That day was the beginning of their clandestine relationship. They began to meet often for dinner and would occasionally spend the night at restaurants without the knowledge of anyone who knew them. However, as time went by, the husband, the boss, began suspecting the two after observing some of the behaviors the two showed towards each other. He decided to hire a private investigator to look into the matter well. It was a fateful evening when Henry and Alice embarked on their affairs as usual in one of the most secluded hotels in town near the beach. The sky was calm and so was the breeze. The two were enjoying their lustful acts when the boss emerged all of a sudden in the hotel room they were! The two were perplexed and petrified beyond words; the bossed looked at them disappointed and then left without uttering a word. The following morning Henry was sacked and embarked on a journey back to London wondering where to

Loophole in the Legal System Essay Example | Topics and Well Written Essays - 500 words

Loophole in the Legal System - Essay Example More specific questions regarding the influence of race on jury decision-making have also emerged from this spate of well-publicised cases: How does a defendant's race influence juror's perception and judgement How does the racial composition of a jury affect its deliberations and final decision Is the influence of race on jurors the same in all trails What difference, if any, would it make if more of the lawyers representing criminal defendants were racial minorities Studies show that Justices of the courts who served from 1789-1962 were socially atypical of the average American background: they came from upper-class families, attended the best law schools, were white male and generally protestant (Abraham, 1962; Ulmer, 1973). This unrepresentative nature of the courts can challenge the legitimacy of an institution. A judicial system of white men can be seen as producing only white man's justice. Another reason one can posit for the desirability of minorities in the judiciary is assimilation. America's heterogeneous population is clustered in groups that thrive along racial, religious, and national-background harmonization (Gordon, 1964). With the Hispanic population growing at a rapid rate, with blacks, Native American Indians, Asians, Jews, and White Anglo-Saxons, America, as a nation, faces the problem of how these groups can exist alongside one another. The United States is a pluralistic society.

School's Pastoral Structure and Pupil Achievement Essay

School's Pastoral Structure and Pupil Achievement - Essay Example According to the report findings  Pastoral Care, rather than the aggregate of actions or exercises that employ its practitioners over time, in essence is the underlying impetus for the care in its implementation. Effective Pastoral Care facilitates optimal education by cultivating open communication between students and practitioners as well as carers and parents. Through discrete consultation and positive attention to the student's personal learning style, pastoral care serves to augment the greatest prospects for quality realisation of each pupil's best. When a pastoral curriculum   succeeds in promoting good relations and feedback in the academic process among all participants, it is an operative element of successful education of the whole person.From this discussion it is clear that  significant research currently indicates that academic structures operating under the auspices of pastoral care can quite easily relapse into an academic exercise less focused on aspects of st udent welfare than issues of social management and organizational expediency, carving a considerable gap between lip-service and actuality.  Distortions of pastoral care transpire when perfunctory notions of education seize control of the comprehensive discipline. The upshot is a dichotomy between pastoral care and the academic curriculum where the educational ambience, frustrated by an obsession with control, intensifies an instinctive power struggle on the part of young people who on the whole are naturally prone to test the limits of independence.   A study of student attitudes toward pastoral care shows that on average pupils mistrust its nuances basically as a further assertion of school authority over their lives (Power 75). When government mandates hold teachers accountable for pupil performance the temptation is to assert more control in the classroom. The National Literacy Strategy intervention may authoritatively approve interactive whole-class teaching but by all indications such policies drive practitioners to more autocratic styles of instruction with little occasion for student discovery and development of intellectual insights. Legislative impositions, deliberated from the inside, tend to repeat time-worn educational models from sheer precedent (Watkins 3). A survey of pastoral curricula across schools in a single London borough distinguished four diverse types: tutorial-centred, tutorial aimed at individual and communal learning, the pastoral curriculum integrated into the responsibilities of the faculties, and, finally, a pastoral curriculum strongly established as the academic culture (Best 19). In his article "Pastoral Care and the Millennium," Ron Best regrets that the 1988 Education Act ironically discourages any real progress on a pastoral outlook for the National Curriculum that might have been designed to advance the very expertise and competence that furthers individual initiative in the context of social accountability (Collins and McNiff 27). In terms of evaluating academic merit, intangible values whose worth is easily ascertained, are cast into doubt and abandoned with neglect. Instead

Property law Essay Example | Topics and Well Written Essays - 2500 words - 3

Property law - Essay Example ie Plc and Target there would be both privity of contract1 and privity of estate2 between Leslie Plc and Target as they were the original lessor and lessee. By the action of Target assigning the lease to Ace the relationship between Leslie and Ace would only be on the basis of privity of estate as there is no contractual relationship between them. Similarly by Leslie selling the property to Rake there would be no privity of contract between Rake and Target or Rake and Ace3, only a privity of estate4. The further subletting of the lease by Ace to Simon creates neither privity of estate of privity of contract as there was no agreement with Rake to sublet the property. If Rake had agreed to the sublet then a privity of estate would have been created and Rake could enforce the repair covenant against Simon5. The differences that apply under privity of contract and privity of estate will affect the ability of Rake to enforce the covenant. Under a privity of contract all covenants bind6 whereas under privity of estate7 only the covenants which are regarded as typically part of the landlord and tenant relationship will be bound8. Privity of estate only affects the benefit and burden on the assignee and the landlord in respect of covenants that touch and concern the land9. Having established the relationship of the parties it is necessary to look as to whether the burden and benefit of the covenants can pass with the assignments. Looking first at the position of pre 1996 leases the general rule was that the original tenant could not pass the burden to the assignee. If the lease began prior to 1996 then the assignment of the tenancy would not absolve Target from the liability10 in accordance with the contract11. This would mean that Target would be bound by the covenants throughout the duration of the lease even though his interest has been assigned12. Covenants in leases are deemed to be made on behalf of the covenantor and his successors in title unless a contrary

Financial Accounting assignment Speech or Presentation

Financial Accounting assignment - Speech or Presentation Example payment of dividend to the preference shareholders is under the discretion of the board of directors of a company, whereas the interest payment for debentures is not under their control. Interests on debentures are tax deductible whereas dividend payments are not. In the case of a company going insolvent, debentures get preference over the preference shares (Harvard, 2009). A stock exchange placing will enable the company to raise the additional funds very rapidly. However the company has to also satisfy the demands of the common shareholders and a number of changes have to be brought in terms of the management and policies. There is also a possibility of another company placing a bid to acquire the company through the stock exchange. A stock exchange placing can also act an effective marketing for the company, as the more people will become aware of the business (Hobson, 2007). A rights issue is offered to all exiting shareholders, as opposed to stock exchange placing where the stocks are open to common public. The shares are issued based on a ratio, for instance, every share qualifies to buy another four shares, for a specified period of time. The shareholders can either accept or reject the offering. There is a possibility that the required capital may not be raised, as the shareholders may not accept the offering. However, the company does not run the risk of adding more shareholders and also taking the risk of mergers and acquisitions (Hobson, 2007 and Keef, 1992). The additional capital required can also be raised by not paying the dividends to the shareholders for the financial year. The main advantage of this method is that there are no additional costs involved in raising capital. However, it is to be noted that the shareholders may not be happy with this decision and it might have a negative effect on the potential investors (Frankfurter, Wood and Wansley, 2003). The net present value is computed by discounting the future savings to present values at

Discuss paper - Essay Example It should be noted that there were a couple of preliminary injections that were injected in the crayfish before using 5HT antagonist for stress exposure within the body. In order to make sure that the research data was not flawed, the researchers made all the hemolymph samples at the same time. Notably the timings were marked to be 10am to 1pm. In addition, the process involved the usage of 25  µl with the string was noted in order to insert in the soft cuticle (Fossat et al. 2014). The analysis of the data gathered during the research work was critically analyzed using non-parametric tests. This is a statistical test which ensures reliable results for research works associated with animal stress. As mentioned in the research paper, the result of the research work marked that there is an avid difference between a stressed and non-stressed animal by â€Å"glucose titers at t=0 (0, 05 ±0, 01  µg/ µl, n=8), t=30 151 (0, 06 ±0, 01  µg/ µl, n=7) and t=60 min (0,076 ±0,007  µg/ µl, n=3) (Fossat et al. 2014)†. The results of the research have surely made researchers give a new thinking schema when it comes to stress in

America Experience in Nineteenth Century Essay Example for Free

America Experience in Nineteenth Century Essay During the half of nineteenth century in America, it really brought in experience to the recently happenings. Throughout this period, more individuals were trying so hard to carve out their own versions of the American dream and create their own definition on citizenship. Despite the obvious diversity of experience, most historians such as, Andrew Carnegie, Mary Church Tyrell and minor individuals argue that the mentioned experience shared commonalities are the foundation of American experience.                  Andrew Carnegie tries too hard to explain the gospel of wealth whereby he states that the rich and the poor can be tied together in harmonious relationship by proper administration of wealth. He says that the contrast between millionaires and cottage laborers currently measures change that has come with civilization. This change in wealth approves to be so beneficial and essential for the progress of the race in refinements of civilization that a house is the household for all. There is no bias in the change in the wealth since today the world obtains commodities at excellent quality prices in which the poor and the rich can enjoy with no prejudice (Andrew 23).                There is a great indifference lynching on the side of the church due to barbarism at homes (Mary 178). She pledges to the forei.gn missionary work that they should inaugurate crusades against barbarism at homes that has conformed hundreds of people into savage. This context is contrary rebellious to biblical teachings since only ignorance and lawlessness to date has led to people criticizing the effort put forth by the churches in the Negro’s behalf.                     During the times, there were wars and fight that took over so as they could get lands to settle in. they fought with the Indians, took over their properties such as, horses and cattle, and carried them away (Chief Joseph 187). The Indians were left homeless and some lost their lives during the wall. The author always prayed that the white men would live as brethren and that the case today. During the times, America was so strong and worked together for a certain goal and that is why they won the battle against the Indians.                     During the century, people in America slept in a ranch and ate cook shack most of the time. During the round up, and occasional other spells, people slept in the open and ate their chuck when squatted on their haunches around the check wagon. Besides feeding on beef and beans, they played wild games whenever the cooky took the notation or one of the waddies would decide to diverge the meat deal by going out and shooting some games (Sheldon 37).                From the past, women have been held responsible for the health of the community a function that is now represented by the health department. Certainly, the military conception to educate children so as they are equipped with kindergartens andare given a decent place for play, these things have traditionally in the hands of women (Jane 64). Most of the departments in modern cities can be traced as women’s traditional activities for example; home cleanliness and wholesome was in the hands of women but recently is represented by Bureau of Teenagers House Inspection                   Chinese people were given an appeal from the American citizens, on the pedestal fund of the Bartholdi Statue of Liberty. Chinese never believed in liberty since they had a lot of hardship while the other nationalities were free (American Missionary 290). This showed inhuman since other countries enjoyed liberty but Chinese did not. Chinese loved and adored liberty but they could not allow the ones denying it to them liberty invite them to a graven image and bow to it. In assumption, from the understanding about the America experience, I concur with the shared idea since most of the history can be approved by the recently happenings.

Poverty Porn Essay Example for Free

Poverty Porn Essay Fundraising is a noble and selfless deed. However, an ethical issue has risen concerning the process of raising funds for poverty-stricken communities. Often, visuals of the harsh lives people in poverty face are portrayed when raising funds. The exploitation of such visuals to increase donations or support a cause is known as poverty pornography (Collin, 2009). Poverty pornography is effective in raising funds but it is incorrect due to the unethical way it is carried out that degrades the poverty-stricken communities. Poverty pornography is widely used by charitable organisations because it is an effective method of collecting donations. Research has shown that negative stimuli which evoke emotion can easily capture an individual’s attention (Murphy, Hill, Ramponi, Calder Barnard, 2010). Images of children as well as those which bring about negative emotions also tend to generate more donations (Burt Strongman, 2005). Thus, the disturbing visuals of dying children and women as well as their harsh living conditions portrayed in poverty pornography is effective in grabbing attention and generating feelings of sympathy. These feelings are then converted into actions whereby donations are increased. Therefore, poverty pornography plays a role in helping poverty-stricken communities as it easily grabs people’s attention and encourages them to increase their donations. However, its method of exploiting visuals that degrade the poverty-stricken communities makes poverty pornography unethical. The exploitation of biased visuals depicts poverty-stricken communities in a negative manner. Common examples are severely malnourished African children staring at the camera, waiting to be â€Å"saved† (Osa, 2010). While it is true that there are malnourished children, there are healthier children too. However, poverty pornography is biased as it does not represent this side of poverty-stricken communities. Although taken for a good cause, a distorted image of them is painted (Opoku-Owusu, 2003). This is unethical as the partial representation degrades them, leaving the impression that they are helpless individuals, waiting for their lives to be taken away and unable to do anything. On the other hand, some charitable organisations try to incorporate positive images into their advertisements by showing the after-effects of our donations. For example, they may show visuals of happy, smiling children as a result of our aid. However, such images indirectly degrade the communities as it gives us the impression that without our assistance, they are unable to survive. In 2001, a poll conducted in United Kingdom discovered that 74% thought that â€Å"Developing countries depend on the money and knowledge of the West to progress† (Voluntary Service Overseas, 2002). From this, we can deduce that many have the perception that poverty-stricken communities are weak and vulnerable as they are highly dependent on our help. However, this may not be true because in reality, they are the most â€Å"strongest willed, most tenacious people one could hope to meet† (Cowdroy Evans, 2010). Thus, the misrepresentation creates a false impression that poverty-stricken communities are weak and cannot survive without our aid. This false impression may also create an environment of self-pity which may lead to self-fulfilling prophecies. The self-fulfilling prophecy, introduced by Merton (1948), refers to circumstances whereby an initial false claim later turns into reality. The exploitation of negative visuals pertaining to the lives of poverty-stricken communities has led to a stereotype that they are â€Å"uneducated, incapable of freeing themselves from poverty, lacking in competence, and miserable† (Clark, 2004). This stereotype may cause people to hold negative expectations on the poverty-stricken communities (Madon, Jussim, Eccles, 1997). Although these negative expectations may not be true initially, the poverty-stricken communities might adhere to them thus leading to a self-fulfilled prophecy. Therefore, the use of poverty pornography to assist them may backfire as incorrect claims can become true. Nevertheless, many organizations unremittingly use poverty pornography. Does this make poverty pornography a necessary evil? Poverty pornography is definitely not a necessary evil. It is unethical to degrade or stereotype the poverty-stricken communities, even if it is for a noble cause. Moreover, poverty pornography can instead contribute to the  poverty cycle as the negative assumptions about the poverty-stricken communities may become self-fulfilling prophecies. Thus, instead of eradicating poverty, it may worsen the conditions of poverty-stricken communities. However what other methods can we adopt to increase awareness on the needs of the poverty-stricken communities without degrading them? Instead of exploiting biased images that generate feelings of sympathy, programmes that create feelings of empathy and responsibility can be created. One such event is the inaugural 30 Hour Famine Camp in Singapore held by World Vision. In this camp, youths are given a feel of life in poverty by taking part in activities that simulates lives of children in poverty. The youths also make a stand to end global poverty by fasting for thirty hours. This camp generates empathy which encourages youths to not only donate but also to think of more ways to assist by allowing them to realise that they have the ability and responsibility to help end poverty. To portray full representation of their lives, some have embarked on projects like ‘Perspectives of Poverty’ which â€Å"expose[s] this bias [poverty pornography] and present people in a light of dignity† (McNiholl, n.d). Even though it may not help in raising funds, by presenting poverty-stricken in a better light, it balances off how degrading poverty pornography has been and slowly alters people’s perception on poverty-stricken communities. This can help remove stereotypes on them thus avoid self-fulfilling prophecies. Poverty pornography has proven to be effective. However, its unethical methods have undermined the usefulness of helping poverty-stricken communities. Instead of assisting, it strips them of their dignity, their ability to help themselves and contribute to the poverty cycle. Even though poverty pornography cannot be eradicated in the near future as it is widely used, the two methods presented above are examples of how we can slowly break away from poverty pornography. People in poverty are human beings too. Thus, in the process of assisting them, we must create a full representation of them and treat them as dignified human beings. To achieve this, poverty pornography must be eradicated. REFERENCES Burt, CDB. Strongman, K. Use Of Images In Charity Advertising: Improving Donations and Compliance Rates.

Tests of Significance: Uses and Limitations

Tests of Significance: Uses and Limitations Abstract Statistical tools are undoubtedly important in decision making. The use of these tools in everyday problems has led to a number of discoveries, conclusions and enhancement of knowledge. This ranges from direct calculations using general statistical formulas to formulas integrated in Statistical software to fasten the process of decision making. Statistical tools for testing hypothesis, significance tests are strong but only if used correctly and in good understanding of their concepts and limitations. Some researchers have indulged into wrong usage of this tests leading to wrong conclusions. This paper looks at the different significance tests (both parametric and non-parametric tests) their uses, when to be used and their limitations. It also evaluates the use of Statistical Significance tests in Information Retrieval and then proceeds to check the different significant tests used by researchers in the papers submitted to Special Interest Group on Information Retrieval (SIGR) in the period 2006, 2007 and 2008. For the combined period 2006-2008, including the years 2006 and 2008, of the papers submitted had statistical tests used and of these tests were used wrongly. Key Words: Significance Test, Information Retrieval, Parametric Tests, Non-parametric Tests, Hypothesis Testing Chapter One 1.0 Introduction Statistical methods play a very important role in all aspects of research, ranging from data collection, recording, analysis, to making conclusions and inferences. The credibility of the research results and conclusions will depend on each and every step mentioned above; any fault made in these steps can render a research carried out for several years, spending millions of shillings to be worthless. This does not mean carrying any test and mincing figures shows that statistics has been used in the given research; the researcher should be able support why he or she used that specific test or method. Misuse of significance test is not new in the world of science. According to Campbell (1974), there are different types of statistical misuse: Discarding unfavorable portion of data This occurs when the researcher selects only a portion of data which produces the results that he/she requires perfectly while discarding the other portion. After a well done research, the researcher might get values that are not consistent to what he/she was expecting. This researcher might decide to ignore this section of data during the analysis so as to get the â€Å"expected results†. This is a wrong take since the inconsistent data could give very new thoughts in that particular field that is if these irregularities are checked and explained why they occurred, more ideas abut that area can be explored.. Overgeneralization Sometimes the conclusions from a research can only work on that particular research problem but the researcher might blindly generalize the results obtained to other kinds of research similar or dissimilar. Overgeneralization is a common mistake in current research activities. A researcher after successfully completing a research on a particular field, he/she might be tempted to make generalizations reached in this research to other fields of study without regarding the different orientations of these different populations and assumptions in them. Non representative sample This arises when the researcher selects a sample which produces results geared towards his/her liking. Sample selected for a particular study should be one that truly represents the entire population. The procedure of selecting the sample units to be used in the study should be done in an unbiased manner. Consciously manipulating data Occurs when a researcher consciously changes the collected data in order to reach a particular conclusion. This is mainly noticed when the researcher knows exactly what the customers aim are, so the researcher changes part of the data so that the aim of that research is covered strongly. For example if a researcher is carrying out a regression analysis and does a scatter plot, if he/she sees that there are many out liers,the researcher might decide to change some values so that the scatter plot appears as a straight line or something very close to that. This act leads to results which are appealing to the customer and the eyes of other user but in real sense does not give a clear indicator of what is really happening in the population at large. 1.0.5 False correlation This is observed when the researcher claims that one factor causes the other while in real sense both two factors are caused by another hidden factor which was not identified during the study. Correlation researches are common in social sciences and sometimes they are not adequately approached, this leads to wanting results. In correlation studies say to check if variable X causes variable Y, in real sense there are four possible things. The first one is that X causes Y,secondly Y causes X, third is X and Y are both caused by another unidentified variable say Z and lastly the correlation between X and Y occurred purely by sheer luck. All these possibilities should be checked while doing these kinds of study to avoid rushing into wrong conclusions. False causality can be eliminated in studies by using two groups for the same experiment that is the â€Å"control group (the one receiving a placebo)† and the â€Å"treatment group (the one receiving the treatment)† . Even though this method is efficient, implementing it raises very many challenges. There are ethical issues like when one patient is given a placebo (effect less drug) without his/her conscious and the other group given the right drug. One question comes to mind; is it ethical to do this to the first group? Carrying out the experiment in parallel for two different groups can also prove to be very expensive. 1.0.6 Overloaded questions. The questions used in survey can really affect the outcome of the survey. The structure of questions in a questionnaires and the method of formulating and asking the questions can influence the manner in which the respondent answers the questions. Long wordy questions in a questionnaire can be too boring to a respondent and he/she might just fill the questionnaire in a hurry so that he/she finishes it but does not really care about the answers that he/she has provided. The framing of questions can also yield leading questions. Some questions will just lead the respondent on what to answer for example â€Å"The government is not offering security to its citizens, do you agree to this? (Yes or No)† Use of statistical significance has been with us for more than 300 years (Huberty, 1993).Despite being used for a long time, this field of decision making is cornered by criticism from all directions, which has led to many researchers writing materials digging into the problems of statistical significance testing. Harlow et. al (1997), discussed the controversy in significance testing in depth. Carver (1993) expressed dislike of significance tests and clearly advocated researchers to stop using them. In his book, How to Lie with Statistics, Huff (1954) outlined errors both intentional and unintentional and misinterpretations made in statistical analyses in depth. Some journals e.g. American Psychological Association (APA) recommended minimum use of statistical significance test by researchers submitting papers for publications (APA, 1996), though not revoking the use of the tests. With the relentless criticism, other researchers have not given up on using statistical significance testing but have clearly encourage users of the tests to have good knowledge in them before making conclusions using them. Mohr (1990) discussed the use of these tests and supported their use but warning researchers to know the limitations of each tests and correct application of the tests so as to make a correct inferences and conclusions. In his paper, Burr (1960) supported the use of statistical significance test but requested researchers to make allowances for existence of statistical errors in the data. Amidst these controversies, statistical significance testing has been applied to many areas of research and remarkable achievements have been recorded. One such area is the information retrieval (IR). Significant tests have been used to compare different algorithms in information retrieval. 1.1.0 Information retrieval Information retrieval is defined as the science of searching databases, World Wide Web and other documents looking for information on a particular subject. In order to get information, the user is required to enter keywords which are to be used for searching, a combination of objects containing the keywords are usually returned from which the user looking for information can single out and pick one which gives him or her the much required information. The user usually progressively refines the search by narrowing down and using specific words. Information retrieval has developed as a highly dynamic and empirical discipline, requiring careful and thorough evaluation to show the superior performance of different new techniques on representative document collections. There are many algorithms for Information Retrieval .It is usually important to measure the performance of different information retrieval systems so as to know which one gives the required information faster. In order to measure information retrieval effectiveness, three test items are required; (i) A collection of documents on which the different retrieval methods will be run on and compared. (ii) A test collection of information needs which are expressible in terms of queries (iii)A collection of â€Å"relevance judgment† that will distinguish on whether the results returned are relevant to the person doing the search or they are irrelevant. A question might arise on which collection of objects to be used in testing different systems. There are several standard test collections used universally, these include; (i) Text Retrieval Conference (TREC). – This a standard collection comprising 6 CDs containing 1.89 million documents (mainly, but not exclusively, newswire articles) and relevance judgments for 450 information needs, which are called topics and specified in detailed text passages. Individual test collections are defined over different subsets of this data. (ii)GOV2-This was developed by The U.S. National Institute of Standards and Technology (NIST).It is a 25 paged collection of web pages. (iii) NII Test Collections for IR Systems (NTCIR)-This is also a large test collection focusing mainly on East Asian language and cross-language information retrieval, where queries are made in one language over a document collection containing documents in one or more other languages. (iii) Cross Language Evaluation Forum (CLEF). This Test collection is mainly focused on European languages and cross-language information retrieval. (iv) 20 Newsgroups. This text collection was collected by Ken Lang. It consists of 1000 articles from each of 20 Usenet newsgroups (the newsgroup name being regarded as the category). After the removal of duplicate articles, as it is usually used, it contains 18941 articles. (v) The Cranfield collection. This is the oldest test collection in allowing precise quantitative measures of information retrieval effectiveness, but is nowadays too small for anything but the most elementary pilot experiments. It was collected in the United Kingdom starting in the late 1950s and it contains 1398 abstracts of aerodynamics journal articles, a set of 225 queries, and exhaustive relevance judgments of all (query, document) pairs. There exist several methods of measuring the performance of retrieval systems namely; Precision, Recall, Fall-Out, E-measure and F-measure just to mention a few since researchers are coming up with other new methods. A brief description of each method will shade some light. 1.1.1 Recall Recall in information retrieval is defined as the number of relevant documents returned from a search divided by the total number of documents that can be retrieved from a database. Recall can also be looked at as evaluating how well the method that is being used to retrieve information gets the required information. Letbe the set of all retrieved objects andbe the set of all relevant objects then, Recall(1.1) As an example, if a database contains 500 documents, out of which 100 contain relevant information required by a researcher, the complement ,number of documents not required = 400. If the researcher uses a system to search for the documents in this database and it return 100 documents of which all of them are relevant to the researcher, then the recall is given by: Recall Supposed that out of 120 returned documents, 30 are irrelevant, then the recall would be given by Recall 1.1.2 Precision Precision is defined as the number of relevant documents retrieved from the system over the total number of documents retrieved in that search. It valuates how well the method being used to retrieve information filters the unwanted information. Letbe the set of all retrieved objects andbe the set of all relevant objects then, Precision(1.2) As an example, if a database contains 500 documents, out of which 100 contain relevant information required by a researcher, the complement ,number of documents not required = 400. If the researcher uses a system to search for the documents in this database and it returns 100 documents of which all of them are relevant to the researcher, then the precision is given by: Precision Supposed that out of 120 returned documents, 30 are irrelevant, then the precision would be given by Precision Both precision and recall are based on one term; Relevance Oxford dictionary defines relevance as â€Å"connected to the issue being discussed†. Yolanda Jones (2004) identified three types of relevance, namely; Subject relevance which is the connection between the subject submitted via a query and subject covered by returned texts. Situational relevance: connection between the situation being considered and texts returned by database system. Motivational relevance: connection between the motivations of a researcher and texts returned by database system. There are two measures of relevance; Novelty Ratio: This refers to the proportion of items returned from a search and acknowledged by the user as being relevant, of which they were previously unaware of. Coverage Ratio: This refers to the proportion of items returned from a search out of the total relevant documents that the user was aware of before he/she started the search. Precision and recall affect each other i.e. increase in recall value decreases precision value. If one increases a system’s ability to retrieve more documents, this implies increasing recall, this will have a drawback since the system will also be retrieving more irrelevant documents hence reducing the precision of that system. This means that a trade-off is required in these two measures so as to ensure better search results. Precision and recall measures make use of the following assumptions They make the assumption that either a system returns a document or doesn’t. They make the assumption that either the document is relevant or not relevant, nothing in between. New methods are being introduced by researchers which rank the degree of relevance of the documents. 1.1. 3 Receiver Operating Characteristics (ROC) Curve This is the plot of the true positive rate or sensitivity against the false positive rate or (1 − specificity).Sensitivity is just another term for recall. The false positive rate is given by. An ROC curve always goes from the bottom left to the top right of the graph. For a good system, the graph climbs steeply on the left side. For unranked result sets, specificity, given bywas not seen as a very useful idea. Because the set of true negatives is always so large, its value would be almost 1 for all information needs (and, correspondingly, the value of the false positive rate would be almost 0). 1.1.4 F-measure and E-measure This is defined as the weighted harmonic mean of the recall and precision. Numerically, it is defined as (1.3) Whereis the weight. Ifis assumed to be 1, then (1.4) The E-measure is given by(1.5) E –measure has a maximum value of 1.0, 1.0 being the best. 1.1.5 Fall-Out This is defined as the proportion of irrelevant documents that are returned in a search out of all the possible irrelevant documents. Fall out(1.6) It can also be defined as the probability of a system retrieving an irrelevant document. These are just a few methods of measuring performance of search systems. Then after looking after one system, there arise a problem of comparing two systems or algorithms, that is, is this system better than the other one? To answer this question, scientist in Information retrieval use statistical significance tests to do the comparisons in order to establish if the difference in systems performance are not by chance. These tests are used to confirm beyond doubt that one system is better than another. Statement of the problem Statistical inference tools like statistical significance tests are important in decision making. Their use has been on the rise in different areas of research. With their rise, novel users make use of these tools but in questionable manners. There are many researchers who do not understand the basic concepts in statistics leading to misuse of the tools. Any conclusions reached from a research might be termed bogus if the statistical tests used in it are shoddy. More light needs to be shade in this area of research to ensure correct use of these tests. Researchers in Information Retrieval also use these tests to compare systems and algorithms, are the conclusions from these tests truly correct? Are there any other ways of comparison which minimize the use of statistical tests? Objectives of the study The objectives of this study are: Investigate use and misuse of statistical significance tests in scientific papers submitted by researchers to SIGIR. Shade light on different statistical significance tests their use, assumptions and limitations. Identify the most important statistical concepts that can provide solutions to the problems of statistical significance in scientific papers submitted by researchers to SIGIR. Investigate the reality of the problems of statistical significance in scientific papers submitted by researchers to SIGIR. Investigate the use of statistical significant tests used by researchers in Information Retrieval Discover the availability of statistical concepts and methods that can provide solutions to the problems of statistical significance in scientific papers submitted by researchers to SIGIR Chapter Two This section of this paper has been divided into three major parts, the sample selection and sample size choosing which will discusses methods of selecting a sample and the size of the sample to be used in a given research, the second part deals with statistical analysis methods and procedures, mainly in significance testing and the third part discusses other statistical methods that can be used in place of statistical significance test. 2.0 Sample Selection and Sample Size 2.0.1 Sample selection Sampling plays a major role in research, according to Cochran (1977), sampling is the process of selecting a portion of the population and using the information derived from this portion to make inferences about the entire population. Sampling has several advantages, namely; (i)Reduced cost For example it is very expensive to carry out a census than just collecting information from a small portion of the population. This is because only a small number of measures will be made so only a few people will be hired to do the job compared to complete census which will require a large labor force. (ii)Greater speed during the process(less time) Since only a few people will be used or rather only a few items will be measured, the time for doing the measurement will be reduced and also summarization of the data will be quick as opposed to when measures are taken for the whole population. (iii)Greater accuracy Since only a few people will be considered in the process, the researchers will be very thorough as compared to the entire population which will see the researchers get tired in the middle of the process leading to lousy collection of data and shoddy analysis. The choice of the sampling units in a given research may affect the credibility of the whole research. The researcher must make sure that the sample being used is not biased, that is it represents the whole population. There are several methods of selecting samples to be used in a study. A researcher should always make sure that the sample drawn is large enough to be a representative of the population as a whole and at the same time manageable. In this section the two major types of sampling, random and non-random, will be examined. 2.0.1.1 Random sampling In random sampling, all the items or individuals in the population have equal chances of being selected into the sample. This procedure ensures that no bias is introduced during the selection of sample units since a n items selection will be only by chance and will not depend on the person assigned with the duty of coming up with the sample. There exist five major random sampling techniques, namely; simple random sampling, multi-stage sampling, stratified sampling, cluster sampling and systematic sampling. The following section discusses each of these. 2.0.1.1.1 Simple random sampling In simple random sampling, each item in the population has the same and equal chance of being included in the sample. Usually each sampling unit is assigned a unique number and then numbers are generated using a random number generator and a sampling unit is included in the sample if its corresponding number is generated from the random number generator. One advantage attributed to simple random sampling is its simplicity and ease in application when dealing with small populations. Every entity in the population has to be enlisted and given a unique number then their respective random numbers be read. This makes this method of sampling very tedious and cumbersome especially where large populations are involved. 2.0.1.1.2 Stratified sampling In stratified random sampling, the entire population is first divided into N disjoint subpopulations .Each sampling unit belongs to one and only one sub population. These sub populations are called strata, they might be of different sizes and they are homogenous within the strata and each stratum completely differs with the other strata. It is from these strata that samples are drawn for a particular study. Examples of strata that are commonly used include States, provinces, Age and Sex, religion, academic ability or marital status etc. Stratification is most useful when the stratifying variables are simple to work with, easy to observe and closely related to the topic of the survey (Sheskin, 1997). Stratification can be used to select more of one group than another. This may be done if it is felt that the responses obtained vary in one group than another. So, if the researcher knows that every entity in each group has much the same value, he/she will only need a small sample to get information for that group; whereas in another group, the values may differ widely and a bigger sample is needed. If you want to combine group level information to get an answer for the whole population, you have to take account of what proportion you selected from each group. This method is mainly used when information is required for only a particular subdivision of the population, administrative convenience is an issue and the sampling problems differ greatly in different portions of the population of study. 2.0.1.1.3 Systematic sampling Systematic sampling is quite different from the other methods of sampling, supposed the population contains N units and a sample of n units is required, a random number is generated using the random number generator, call it k, then a unit(represented as a number) is drown from the sample then the researcher picks every kth unit thereafter. Consider the example that k is 20 and the first unit that is drawn is 5, the subsequent units will be 25,45,65,85 and so on. The implication of this method is that the selection of the whole sample will be determined by only the first item since the rest will be obtained sequentially. This type is called an every kth systematic sample. This technique can also be used when questioning people in a sample survey. A researcher might select every 15th person who enters a particular store, after selecting a person at random as a starting point; or interview the shopkeepers of every 3rd shop in a street, after selecting a starting shop at random. It may be that a researcher wants to select a fixed size sample. In this case, it is first necessary to know the whole population size from which the sample is being selected. The appropriate sampling interval, I, is then calculated by dividing population size, N, by required sample size, n. This method is advantageous since it is easy and it is more precise than simple random sampling. Also it is simpler in systematic sampling to select one random number and then every kth member on the list, than to select as many random numbers as sample size. It also gives a good spread right across the population. A disadvantage is that the researcher may be forced to have a starting list if he/she wishes to know the sample size and calculate the sampling interval. 2.0.1.1.4 Cluster sampling The Austarlian Bureau of Statistics insinuates that cluster sampling divides the population into groups, or clusters. A number of clusters are selected randomly to represent the population, and then all units within selected clusters are included in the sample. No units from non-selected clusters are included in the sample. They are represented by those from selected clusters. This differs from stratified sampling, where some units are selected from each group. The clusters are heterogeneous within each cluster (that is the sampling units inside a cluster vary from each other completely) and each cluster looks alike with the other clusters. Cluster sampling has several advantages which include reduced costs, simplified field work and administration is more convenient. Instead of having a sample scattered over the entire coverage region, the sample is more concentrated in relatively few collection points (clusters). Cluster sampling provides results that are less accurate compared to stratified random sampling. 2.0.1.1.5 Multi-stage sampling Multi-stage sampling is like cluster sampling, but involves selecting a sample within each chosen cluster, rather than including all units in the cluster. The Australian Bureau of Statistics postulates that multi-stage sampling involves selecting a sample in at least two stages. In the first stage, large groups or clusters are selected. These clusters are designed to contain more population units than are required for the final sample. In the second stage, population units are chosen from selected clusters to derive a final sample. If more than two stages are used, the process of choosing population units within clusters continues until the final sample is achieved. If two stages are used then it will be called a two stage sampling, if three stages are used it will be called a three stage sampling and so on. 2.0.2 Determination of sample size to be used 2.1 Statistical Analysis In this section, different statistical tests are discussed in details in their general form, then move to discussed how each of them(the ones used in IR) are applied to information retrieval. Only some of these tests are used to compare systems or/and algorithms. In this paper we look at three sections of statistical analysis, namely: (i) Summarizing data using a single value. (ii) Summarizing variability. (iii) Summarizing data using an interval (no specific value) In the first case, we have the mean, mode, median etc and in the second case, we look at variability in the data and in the third case we look at the confidence intervals, parametric and nonparametric tests of hypothesis testing 2.1.1 Summarizing data using a single value In this case, the data being analyzed is represented by a single value, example for this scenario are discussed below: 2.1.1.1 Mean There are three different kinds of mean: (i)Arithmetic mean (ii)Geometric Mean (iii)Harmonic mean (i) Arithmetic mean This is computed by summing all the observations then dividing by the number of observations that you have collected. Letbe n observations of a random variable X. The arithmetic mean is defined as Arithmetic mean When to use the arithmetic mean The arithmetic mean is used when: When the collected data is a numeric observation. When the data has only one mode (uni-modal) When the data is not skewed i.e. not concentrated to extreme values. When the data does not have many outliers (very extreme values) The arithmetic mean is not used when: You have categorical data When the data is extremely skewed. (ii) Geometric mean This is defined as the product of the observations, everything raised to power of, usually n. Letbe n observations of a random variable X. The geometric mean is defined as Geometric mean The Geometric mean is used when: The observations are numeric. The item that we are interested in is the product of the observations. (iii) Harmonic mean This is defined as the number of observations divide be the sum of reciprocals of the observations. Letbe n observations of a random variable X. The harmonic mean is defined as Harmonic mean The Harmonic mean is used when: The average can be justified for the reciprocal of the observations. 2.1.1.2 Median This is defined as the middle value of the observations. The observations are first arranged in ascending or descending order then the middle value is taken as the median. The median is used when: When the observations are skewed. The observations have a single mode. The observations are numerical. The median is not used when: We are interested in the total value. 2.1.1.3 Mode This is defined as the largest value in the given dataset or the value that has the highest frequency of occurrence. The mode is used when: The dataset is categorical. The dataset is both numeric and multimodal. 2.1.2 Summarizing variability Variability in a data can be summarized using the following measures: 2.1.2.1 Sample variance Letbe n observations of a random variable X, then the Sample variance, is given by The standard deviation is used when: The data is normally distributed. 2.1.2.2 The C

The Death Of Abraham Lincoln - The Pinkey Or The Bullet :: essays research papers fc

Lincoln   Ã‚  Ã‚  Ã‚  Ã‚  Many people â€Å"think† that they know about the Lincoln assassination. There are two theories on the death of Abraham Lincoln. The first theory is that of John Wilkes Booth shooting Lincoln in the cerebrum. The second theory is that a doctor misplaced his pinkie finger when assisting Lincoln to a hospital. Many people believe that the doctor’s finger actually pushed the bullet further into Lincoln’s brain, leading to his death. This research paper will compare and contrast the different theories and viewpoints about how Lincoln was assassinated. (Norton)   Ã‚  Ã‚  Ã‚  Ã‚  Abraham Lincoln was born on Sunday, February 12, 1809, in a log cabin in Kentucky. In his early life, he worked jobs including; running a store, surveying, and serving as a postmaster in New Orleans. There, Lincoln lived, worked, and he even wrestled the town bully, earning him the nickname, â€Å"Honest Abe†. Later on in life, Lincoln got married to a woman named Mary Todd. They had four children; Robert (1843 - 1926), Edward (1846 - 1850), William (1850 - 1862), and Thomas (1853 - 1871). Later on, Lincoln became an attorney, decided to settle down and buy a house in Springfield. (Norton) In 1846 Lincoln ran for the United States House of Representatives and won. He was well known throughout the political world for his opposition to the Mexican War and his will to put an end to slavery. In 1860, Lincoln won on the third ballot and was elected the 16th President of the United States on November 6, winning over Stephen A. Douglas. (Norton)   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  On April 14, 1865, the Lincoln family attended a play entitled â€Å"Our American Cousin†, at Ford’s Theater. At about 10:15 P.M. Lincoln was shot in the brain by John Wilkes Booth.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Booth was the ninth out of ten children. He was born in Bel Air, Maryland in 1838. Booth was an actor and chose not to fight in the Civil War, his sympathies lay with the South and against President Lincoln. As the Confederacy began to lose, Booth’s hatred of Lincoln became stronger and stronger. He eventually began to plot against the President. Booth fired a single shot - .44 - caliber Derringer into Lincoln’s head, behind the left ear (according to the book, â€Å"True Crime: Assassination†), by the editors of Time - Life Books. After the shooting, Booth leaped for the stage. One of his spurs got caught in a flag, and he broke his leg after landing on the stage. (Lattimer)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  He staggered to his feet and shouted: â€Å"Sic semper tyrannis!† - meaning, â€Å"Thus always to tyrants!† On April 26, he was caught by Union soldiers on a farm near Bowling

Julius Caesar - Mark Antony :: essays research papers

Mark Antony The character of Mark Antony from Shakespeare’s play Julius Caesar may be viewed as simply the confident and devoted supporter of Julius Caesar. On the contrary, Antony presents the qualities of a shrewd flatterer, a ruthless tyrant, as well as a loyal follower. Antony’s characteristics will change as the play progresses. He will begin using flattery to get what he wants, but he will eventually depend on his powerful relentlessness. Furthermore, Antony uses these various attributes to make him successful. Throughout the play, Antony uses flattering to achieve his goals. Following the assassination of Caesar, Antony quickly grasps that he must deal with Brutus, and he has the shrewdness to take advantage of Brutus’s gullibility. Antony has his servant say, "Brutus is noble, wise, valiant, and honest" (III i 126). From this point, it is clear that Antony intends to flatter Brutus and to work upon those personal qualities of Brutus which represent his fundamental weaknesses. Antony then comes to the Capitol where he further flatters the conspirators by shaking their hands and saying, "Friends am I with you all, and love you all..." (III i 220). This act symbolizes that Antony has made a new friendship with the conspirators, but in reality, he is plotting to seek revenge so he can take over Rome. Antony is also able to flatter the vast angry crowd in order to get his way. He is first able to get the crowd to feel sorry for him. This feeling is evident when the second plebeian says, "Poor soul, his eyes are red as fire with weeping" (III ii 116). Antony is then able to turn the people in the crowd against Brutus by teasing them with Caesar’s will. Antony says, "And being men, hearing the will of Caesar, it will inflame you, it will make you mad" (III ii 144-145). This blandishment provokes an immediate response of the crowd demanding that Antony read Caesar’s will. Although Antony uses flattery to get what he wants, he will also show respect for others with his devotion and loyalty. One of the most significant characteristics of Mark Antony is his strong, affectionate loyalty to Julius Caesar. Antony’s devotion to Caesar extends beyond a simple friendship, but politically as well. This fact is best recognized when he offers Caesar the crown of Rome three times in the beginning of the play. This act shows that Antony is dedicated to Caesar because he is quite willing to serve under the rule of an ambitious tyrant. Immediately following the assassination of Caesar, Antony acts as though he Julius Caesar - Mark Antony :: essays research papers Mark Antony The character of Mark Antony from Shakespeare’s play Julius Caesar may be viewed as simply the confident and devoted supporter of Julius Caesar.

What Affects the Strength of an Electromagnet? Essay -- essays researc

What Affects the Strength of an Electromagnet? Aim What is the effect of increasing the current and increasing the number of coils when picking up paper clips? Definition First of all, an electromagnet has to be defined. An electromagnet can also be called a Solenoid, Which consists of a core of iron and then wire is wrapped round it. Prediction I predict that as the current carried in the wire gets stronger, so will the magnetic field surrounding the electromagnet. Therefore, I think that the amount of paper clips picked up will increase as the voltage gets higher until the electromagnet can't pick up any more paper clips. I also predict that the more coils wrapped round the wire creates a bigger magnetic field allowing more paper clips to be picked up. Variables Thickness Coils Length of wire Core Material If the paper clips are already slightly magnetized from previous experiments Weight of the Paperclips Number of Paperclips available Equipment Mat - (To protect the surface of the bench) Power Pack - (To control the voltage of the current) *Battery Pack – (To control the voltage of the current) Crocodile Clips - (To take the electricity to the Electromagnet) Paper Clips – (To test the conductivity of the Electromagnet) Electromagnet Iron Nail - (to act as a core) Wire - (wrapped around the core) Test the Voltage Method 1. Take the Iron rod and wind the wire around it, leaving the two ends of the wire free. 2. Plug two crocodile clip leads into the Power pack and attach each crocodile clip to a different end of the wire which is wound around the rod. 3. Turn on the power to the required voltage (I had a problem with the power pack because they kept short circuiting so I decided to use a battery pack but they would drain very quickly and could only test 2, 4, and 6 volts) and then bring the box of paper clips up so that they are touching the Iron rod 4. If there are any paper clips still hanging, take them off and count them and record the results The above method was repeated at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 & 12 Volts. Testing the Number of Wires Method 1. Take the Iron rod and wind the wire around it 10 times increasing the number of coils by 10 each time up to 100 coils, leaving the two ends of the wire free. 2. Plug two crocodile clip leads into the Power pack and attach each crocodile clip to a different end of the wire which ... ...;  Ã‚  Ã‚  Ã‚  4.60  Ã‚  Ã‚  Ã‚  Ã‚  50  Ã‚  Ã‚  Ã‚  Ã‚  51  Ã‚  Ã‚  Ã‚  Ã‚  45  Ã‚  Ã‚  Ã‚  Ã‚  51  Ã‚  Ã‚  Ã‚  Ã‚  49 12  Ã‚  Ã‚  Ã‚  Ã‚  5.00  Ã‚  Ã‚  Ã‚  Ã‚  50  Ã‚  Ã‚  Ã‚  Ã‚  53  Ã‚  Ã‚  Ã‚  Ã‚  45  Ã‚  Ã‚  Ã‚  Ã‚  46  Ã‚  Ã‚  Ã‚  Ã‚  48 Conclusion The results did show that my predictions had been right. The amount of paper clips increased by increasing voltage or by increasing the no. of coils(as Shown on the graph). The fact that the electromagnet gets stronger or weaker as you change the voltage is a useful one and the fact that the magnetic field gets bigger depending on how many no. of coils and gets stronger for how much voltage is passed through the coils. Probably the reason that some of the results were anomalous because some of the paperclips may have become magnetised, or the Rod may have become a weak permanent magnet. My best fit line didn't pass through the origin, although it came very close. This is probably because the iron rod became slightly magnetised and acted as a weak permanent magnet, before it was connected.
