Utilitarian Ethics in Philosophy

Introduction Ethics is an important aspect of humanity that distinguishes people from animals. However, an analysis of multiple issues related to the subject of ethics may raise uncertainty and confusion. Deciding what is right or wrong is not clear-cut. Thus, several philosophers developed several frameworks from which one could understand the subject of ethics.Advertising We will write a custom essay sample on Utilitarian Ethics in Philosophy specifically for you for only $16.05 $11/page Learn More As a result, the principle of utilitarianism falls among the most important frameworks in which one can apply ethics. Utilitarianism is both a practical and a logical approach of viewing the subject of ethics. This paper defends the principle of utilitarianism as an important perspective to use when applying ethics. A utilitarian views a right or a wrong action from a practical threshold, which holds that if some acts bring benefits to most people, they may be considered as the right ones, while if some deeds result in negative outcomes to the majority, they are meant to be wrong (Hammond 38). One can clearly see that utilitarian ethic is both practical and simple in use, when compared to other types of ethics (Hammond 40). Other types of ethics, such as virtual ethics, are obviously ambiguous in several respects (Hammond 43). For instance, people hold different and sometimes opposite views on ethics (Hammond 48). Consider, for example, the issue of euthanasia. While some people think that it is absolutely wrong to take away somebody’s life, others believe in the opposite calling it â€Å"good death†. Since it gives a person an opportunity to determine according to one’s views if such an action can bring good to people, utilitarian ethics eliminates ambiguities that originate with other types of ethics (Hammond 35). Another important argument for the application of utilitarian ethics lies in its capacity to avoid a need to determine an absolutely right or wrong principle, which is often unattainable in fact (Hammond 45). The vanity of attempting to classify an action as right or wrong is evident (Hammond 31). Governing laws in several countries recognize the room for giving exceptions to some offences depending on circumstances. For example, some countries that do not allow abortions make exceptions for the unique circumstances, when the unborn child can kill the mother; due to such a threat, a doctor can do abortion.Advertising Looking for essay on ethics?

The examples above are just a few among a database of utilitarian moral principles that shape laws and guide the general life of the society (Hammond 42). In some cases, everyone should adopt utilitarian et hics in his/her daily activities. Besides, utilitarian ethics gives a clear framework for deciding on an important choice when faced with a dilemma. Such a case is especially true for leaders, or those in positions that lay heavy responsibilities with them. Consider an army commander who is to make a decision if it is necessary to use an annihilating force against an enemy that poses a potential threat to the country (Hammond 50). When such a commander applies utilitarian ethics to evaluate his/her decision, he/she will need to consider if utter annihilation of the enemy force will lead to more benefits for his/her nation and the world; thus, a person will have a clear platform on which the one can base his/her moral actions (Hammond 56). Importantly, utilitarian ethics brings a sense of responsibility to people and can build an honest personality as well. It allows to judge morals from a perspective that does not consider the benefits that such an action will bring to people. A per son who applies deontological or virtual ethics may practice a type of morality that has an origin in one’s childhood or environmental background. Often, such an influence does not take into account the dynamics the one is facing. Such a direction can limit the choices and make individual practice right morals. Since a utilitarian considers the issue at hand, he/she bases his/her decisions on his/her sense of responsibility and honesty, while applying his/her ethics. Some philosophers point out an unclear line between happiness and sadness as an inherent weakness in utilitarian ethics (Hammond 41). Since pleasure depends on multiple factors, which include culture, beliefs and psychology, it is sometimes difficult to decide whether an action will benefit most people. Here, the utilitarian perspective stands that while people may disagree on several components of advantage or disadvantage, it is clear that some actions may bring a degree of general comfort and enhance well-bein g of most people. For example, an action that will reduce poverty within the society is generally acceptable as a right action in the perspective of utilitarianism. However, as it clear from western societies, reducing poverty, although it eliminates some form of suffering, does not itself guarantee a construction of happy society. The society then concentrates on the other needs, which determine its overall state of satisfaction with life.Advertising We will write a custom essay sample on Utilitarian Ethics in Philosophy specifically for you for only $16.05 $11/page Learn More Still, one cannot blame an initiative of solving the issue of poverty for the emerging needs of a wealthy society. One should not stop to dream of a society free of violence and crime because managing such an issue can lead to more challenges (and needs) for future societies. Moreover, one cannot stop attempting to decide on an action that can potentially be advantageous to the l argest segment of the population simply because the society may evolve new needs (Hammond 39). The lack of a universal set of moral standards in utilitarian ethics may create concern for some philosophers (Hammond 57). Since moral decisions are often left at the discretion of people (or small parties) to decide what is potentially good for the major part of the community, there is a potential risk to make wrong choices. Still, it is unfair to judge utilitarianism from such a perspective since other type of ethics, such as deontological ethics, falls in a similar category. Even a supporter of virtual ethics will admit that he/she often regrets for some moral decisions he/she has made. Similarly, when making a decision, one cannot remain absolutely certain that whatever he/she does will benefit the largest segment of the community (Hammond 47). However, since such a person makes moral decisions based on his/her own view, one cannot avoid bias and an opportunity to be wrong due to oneà ¢â‚¬â„¢s limitations and lack of knowledge. Conclusion The issue of ethics needs an evaluation that considers crucial dynamics in our society. Here, the conflicting ethical values within communities and the unique nature of situations that require individuals to make moral decisions are the specific factors that one needs to consider when reviewing ethics. Besides, varying cultural, religious, educational and social dynamics within countries make it difficult to develop universal ethics (Hammond 50). Utilitarian ethics provides a foundation for addressing the above mentioned trends that arise in society. When applying utilitarian ethics, the most important consideration, which is a common interest for everyone, is the benefit it may give to the general population (Hammond 42).

David essays

David essays The term Renaissance (approx 1400-1520AD) art seems to draw to mind feelings of a rebirth, a reincarnation of artistic expression in a sense. For Donatello though, living amongst such a time period did not seem to skew his artistic grandeur. In creating his sculptural rendition of the biblical character David, he employed classical models in order to convey a sense of realism. His stylistic approach in crating David was of a type uncommon and un-witnessed since the days of the classical era. Dating around 1440 AD, it was the first large-scale bronze nude statue in the renaissance. Donatello took great inspiration from classical models when he created his sculpture of David. His model for David though did not turn out to be a Greek youth in his prime. Instead, he seems to have chosen a barely developed adolescent boy, with a great deal of feminine features. David is mainly a closed-form sculpture cast out of bronze. The objects represented throughout the sculpture as well as his limbs appear in a type of S-curve stance balancing his human form. His arms appear to be a little more then feeble due to lack of muscle and he also seems to be having trouble holding the sword letting it rest to his side. Almost looking seamlessly, the sword appears to provide stability to the arm securing its construction. He stands on Goliaths head in almost a skeptical pose making an audience wonder if it could all be possible that he accomplished such a feat. His archaic smile leaves him himself even astonished giving a look of awe as he glances down. Donatello was one of the most important fifteenth century artists whose bronze David appears to be an enigma as it is completely unlike his other works in its unusual style, and classical time of origin. The major distinction with Greek art was that it was extremely narrative; in accordance is the sculpture of David. David is seen wearing a broad-brimmed hat that is garlanded wit...

In The Coral Island Ralph, Jack and Peterkin are cast away on a desert island, where they live active, civilized, and civilizing lives. Practical difficulties are easily surmounted; they light fires with bowstrings and spyglasses, hunt pigs for food, and kill them with much ease and a total absence of guiltindeed of bloodshed. They are all Britonsa term they use to compliment each other all brave, obedient and honourable. There is much useful information conveyed concerning tropical islands, including fieldworkers' reporting of the conduct of cannibals: but anthropology is something nasty that clears up on the arrival of a missionary, and Jack himself prevents an act of cannibalism by telling the flatnoses not to be such blockheads and presenting them with six newly slaughtered pigs. The parallel between the island and the Earthly Paradise causes a trace of literary sophistication: 'Meat and drink on the same tree! My de ar boys, we're set up for life; it must be the ancient paradisehurrah! . . . We afterwards found, however, that these lovely islands were very unlike Paradise in many things.' But these 'things' are non-Christian natives and, later, pirates; the boys themselves are cleanly (cold baths recommended) and godlyregenerate, empire-building boys, who know by instinct how to turn paradise into a British protectorate. The Coral Island could be used as a document in the history of ideas; it belongs inseparably to the period when boys were sent out of Arnoldian schools certified free of Original Sin. Golding takes Ralph, Jack and Peterkin (altering this name to Simon, 'called Peter') and studies them against an altered moral landscape. He is a schoolmaster, and knows boys well enough to make their collapse into savagery plausible, to see them as the cannibals; the authority of the grown-ups is all there is to prevent savagery. If you dropped these boys into an Earthly Paradise 'they would not behave like God-fearing English gentlemen' but 'as like as not . . . find savages who were kindly and uncomplicated. . . The devil would rise out of the intellectual complications of the three white men.' Golding leaves the noble savages out of Lord of the Flies but this remark is worth quoting because it states the intellectual position in its basic simplicity. It is the civilized who are corrupt, out of phase with natural rhythm. Lord of the Flies Essay Writing Service Lord of the Flies book review writing is not easy for most students.

Critical appraisal of a qualitative research paper Essay

Critical appraisal of a qualitative research paper - Essay Example he review links potential findings of the study to a wider framework of theoretical knowledge in the area of community health services and helps the reader identify gaps in the existing body of knowledge and justify the need for their study. Such synthesis of relevant information relating to the previous research provides adequate background to the study. Specific nature of the formulated research purposes raised a set of specific requirements to be addressed within a certain methodological framework. The context of study undertaken by Bissel and colleagues suggests that the choice of qualitative approach is the most appropriate alternative in this case. Such choice of methodology and research design is absolutely justified by the formulated research purposes and obtained results: the type of reasoning utilised by Bissel and colleagues is apparently inductive: the authors do not formulate any specific hypothesis or suggest a theory to be tested. Instead, they offer several research objectives to be fulfilled. Data gathering techniques chosen by the authors within the qualitative methodology are congruent with the purposes of their study. The authors prefer semi-structured interview is the instrument of data collection. Semi-structured interview is one of the most popular types of interviewing due to several reasons. Firstly, semi-structured interviewing allow for focused two-way communication. Secondly, while the questionnaire framework implies formulation of detailed questions, a semi-structured interview starts with more general topic or questions, identified ahead of time, and makes it possible for the interviewer to seek for relationships between the questions/topic and variety of relevant issues. The answers given by the interviewee serve as the basis for more specific questions formulated during the interview. And finally, semi-structured interviewing is not as time-consuming and costly as other qualitative methods, while the data is valid, diverse and

Act Utilitarianism Essay Example for Free

Act Utilitarianism Essay Utilitarianism is a theory in normative ethics holding that the proper course of action is the one that maximizes overall happiness. It is now generally taken to be a form of consequentialism, although when Anscombe first introduced that term it was to distinguish between old-fashioned Utilitarianism and consequentialism. [1] According to utilitarianism the moral worth of an action is determined only by its resulting outcome although there is debate over how much consideration should be given to actual consequences, foreseen consequences and intended consequences. Two influential contributors to this theory are Jeremy Bentham and John Stuart Mill. In A Fragment on Government Bentham says ‘it is the greatest happiness of the greatest number that is the measure of right and wrong’ and describes this as a fundamental axiom. In An Introduction to the Principles of Morals and Legislation he talks of ‘the principle of utility’ but later prefers â€Å"the greatest happiness principle. [2][3] Utilitarianism can be characterized as a quantitative and reductionist approach to ethics. It is a type of naturalism. [4] It can be contrasted with deontological ethics,[5] which does not regard the consequences of an act as a determinant of its moral worth; virtue ethics,[6] which primarily focuses on acts and habits leading to happiness; pragmatic ethics; as well as with ethical egoism and other varieties of consequentialism. [7] Utilitarianism has often been considered the natural ethic of a democracy operating by simple majority without protection of individual rights. [8] Early utilitarianism The importance of happiness as an end for humans has long been recognized. Forms of hedonism were put forward by Aristippus and Epicurus; Aristotle argued that eudaimonia is the highest human good and Augustine wrote that all men agree in desiring the last end, which is happiness. Happiness was also explored in depth by Aquinas[9][10][11][12][13] However, utilitarianism as a distinct ethical position only emerged in the eighteenth century. Although utilitarianism is usually thought to start with Jeremy Bentham there were earlier writers who presented theories that were strikingly similar. In An Enquiry Concerning the Principles of Morals David Hume writes: In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind. [14] Hume had studied under Francis Hutcheson and it was he who first introduced a key utilitarian phrase. In An Inquiry into the Original of Our Ideas of Beauty and Virtue (1725) Hutcheson writes, In comparing the moral qualitys of actions, in order to regulate our election among various actions proposed, or to find which of them has the greatest moral excellency, we are led by our moral sense of virtue to judge thus; that in equal degrees of happiness, expected to proceed from the action, the virtue is in proportion to the number of persons to whom the happiness shall extend (and here the dignity, or moral importance of persons, may compensate numbers); And in equal numbers, the virtue is as the quantity of the happiness, or natural good; or that the virtue is in a compound ratio of the quantity of good, and number of enjoyers. In the same manner, the moral evil, or vice, is as the degree of misery, and number of sufferers; so that, that action is best, which procures the greatest happiness for the greatest numbers; and that, worst, which, in like manner, occasions misery. [15]. In the first three editions of the book Hutcheson followed this passage with various mathematical algorithms â€Å"to compute the Morality of any Actions†. In this he pre-figured the hedonic calculus of Bentham. It is claimed[16] that the first systematic theory of utilitarian ethics was developed by John Gay. In Concerning the Fundamental Principle of Virtue or Morality (1731) Gay argues that. Utilitarianism â€Å"happiness, private happiness, is the proper or ultimate end of all our actions†¦ each particular action may be said to have its proper and peculiar end†¦(but)†¦. they still tend or ought to tend to something farther; as is evident from hence, viz. that a man may ask and expect a reason why either of them are pursued: now to ask the reason of any action or pursuit, is only to enquire into the end of it: but to expect a reason, i. e. an end, to be assigned for an ultimate end, is absurd. To ask why I pursue happiness, will admit of no other answer than an explanation of the terms. †[17] This pursuit of happiness is given a theological basis: â€Å"Now it is evident from the nature of God, viz.his being infinitely happy in himself from all eternity, and from his goodness manifested in his works, that he could have no other design in creating mankind than their happiness; and therefore he wills their happiness; therefore the means of their happiness: therefore that my behaviour, as far as it may be a means of the happiness of mankind, should be such†¦thus the will of God is the immediate criterion of Virtue, and the happiness of mankind the criterion of the wilt of God; and therefore the happiness of mankind may be said to be the criterion of virtue, but once removed†¦(and)†¦ I am to do whatever lies in my power towards promoting the happiness of mankind. [18] Gay’s theological utilitarianism was developed and popularized by William Paley. It has been claimed that Paley was not a very original thinker and that the philosophical part of his treatise on ethics is â€Å"an assemblage of ideas developed by others and is presented to be learned by students rather than debated by colleagues. †[19] Nevertheless, his book The Principles of Moral and Political Philosophy (1785) was a required text at Cambridge[19] and Smith says that Paley’s writings were â€Å"once as well known in American colleges as were the readers and spellers of William McGuffey and Noah Webster in the elementary schools. †[20] Although now largely missing from the philosophical canon, Schneewind writes that utilitarianism first became widely known in England through the work of William Paley. [21] The now forgotten significance of Paley can be judged from the title of Birks 1874 work Modern Utilitarianism or the Systems of Paley, Bentham and Mill Examined and Compared. Apart from restating that happiness as an end is grounded in the nature of God, Paley also discusses the place of rules. He writes, â€Å"†¦actions are to be estimated by their tendency. Whatever is expedient, is right. It is the utility of any moral rule alone, which constitutes the obligation of it. Modern Utilitarianism by T. R. Birks 1874 2 But to all this there seems a plain objection, viz. that many actions are useful, which no man in his senses will allow to be right. There are occasions, in which the hand of the assassin would be very useful†¦ The true answer is this; that these actions, after all, are not useful, and for that reason, and that alone, are not right. To see this point perfectly, it must be observed that the bad consequences of actions are twofold, particular and general. The particular bad consequence of an action, is the mischief which that single action directly and immediately occasions. The general bad consequence is, the violation of some necessary or useful general rule†¦ You cannot permit one action and forbid another, without showing a difference between them. Consequently, the same sort of actions must be generally permitted or generally forbidden. Where, Utilitarianism therefore, the general permission of them would be pernicious, it becomes necessary to lay down and support the rule which generally forbids them. †[22] 3 Classical utilitarianism Jeremy Bentham Benthams book An Introduction to the Principles of Morals and Legislation was printed in 1780 but not published until 1789. It is possible that Bentham was spurred on to publish after he saw the success of Paley’s The Principles of Moral and Political Philosophy. [23] Benthams book was not an immediate success[24] but his ideas were spread further when Pierre Etienne Louis Dumont translated edited selections from a variety of Benthams manuscripts into French. Traite de legislation civile et penale was published in 1802 and then later retranslated back into English by Hildreth as The Theory of Legislation, although by this time significant portions of Dumont’s work had already been retranslated and incorporated into Sir John Bowrings edition of Benthams works, which was issued in parts between 1838 and 1843. Benthams work opens with a statement of the principle of utility, â€Å"Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do†¦ By the principle of utility is meant that principle which approves or disapproves of every action whatsoever according to the tendency it appears to have to augment or diminish the happiness of the party whose interest is in question: or, what is the same thing in other words to promote or to oppose that happiness. I say of every action whatsoever, and therefore not only of every action of a private individual, but of every measure of government. †[25] In Chapter IV Bentham introduces a method of calculating the value of pleasures and pains, which has come to be known as the hedonic calculus. Bentham says that the value of a pleasure or pain, considered by itself, can be measured according to its intensity, duration, certainty/uncertainty and propinquity/remoteness. In addition, it is necessary to consider â€Å"the tendency of any act by which it is produced† and, therefore, to take account of the act’s fecundity, or the chance it has of being followed by sensations of the same kind and its purity, or the chance it has of not being followed by sensations of the opposite kind. Finally, it is necessary to consider the extent, or the number of people affected by the action. Perhaps aware that Hutcheson eventually removed his algorithms for calculating the greatest happiness because they â€Å"appear’d useless, and were disagreeable to some readers†[26] Bentham contends that there is nothing novel or unwarranted about his method for â€Å"in all this there is nothing but what the practice of mankind, wheresoever they have a clear view of their own interest, is perfectly conformable to. † Rosen warns that descriptions of utilitarianism can bear â€Å"little resemblance historically to utilitarians like Bentham and J. S. Mill† and can be more â€Å"a crude version of act utilitarianism conceived in the twentieth century as a straw man to be attacked and rejected. †[27] It is a mistake to think that Bentham is not concerned with rules. His seminal work is concerned with the principles of legislation and the hedonic calculus is introduced with the words â€Å"Pleasures then, and the avoidance of pains, are the ends that the legislator has in view. † In Chapter VII Bentham says, â€Å"The business of government is to promote the happiness of the society, by punishing and rewarding†¦ In proportion as an act tends to disturb that happiness, in proportion as the tendency of it is pernicious, will be the demand it creates for punishment. † The question then arises as to when, if at all, it might legitimate to break the law. This is considered in The Theory of Legislation where Bentham distinguishes between evils of the first and second orders. Those of the first order are the more immediate consequences; those of the second are when the consequences spread through the community causing ‘alarm’ and ‘danger’. Utilitarianism â€Å"It is true there are cases in which, if we confine ourselves to the effects of the first order, the good will have an incontestable preponderance over the evil. Were the offence considered only under this point of view, it would not be easy to assign any good reasons to justify the rigour of the laws. Every thing depends upon the evil of the second order; it is this which gives to such actions the character of crime, and which makes punishment necessary. Let us take, for example, the physical desire of satisfying hunger. Let a beggar, pressed by hunger, steal from a rich mans house a loaf, which perhaps saves him from starving, can it be possible to compare the good which the thief acquires for himself, with the evil which the rich man suffers? †¦ It is not on account of the evil of the first order that it is necessary to erect these actions into offences, but on account of the evil of the second order. †[28] 4 John Stuart Mill Mill was brought up as a Benthamite with the explicit intention that would carry on the cause of utilitarianism. [29] Mills book Utilitarianism first appeared as a series of three articles published in Frasers Magazine in 1861 and was reprinted as a single book in 1863. Higher and lower pleasures Mill rejects a purely quantitative measurement of utility and says, â€Å"It is quite compatible with the principle of utility to recognise the fact, that some kinds of pleasure are more desirable and more valuable than others. It would be absurd that while, in estimating all other things, quality is considered as well as quantity, the estimation of pleasures should be supposed to depend on quantity alone. †[30] Mill notes that, contrary to what its critics might say, there is â€Å"no known Epicurean theory of life which does not assign to the pleasures of the intellect†¦ a much higher value as pleasures than to those of mere sensation. † However, he accepts that this is usually because the intellectual pleasures are thought to have circumstantial advantages, i. e. â€Å"greater permanency, safety, uncostliness, c. † Instead, Mill will argue that some pleasures are intrinsically better than others. The accusation that hedonism is â€Å"doctrine worthy only of swine† has a long history. In Nicomachean Ethics (Book 1 Chapter 5) Aristotle says that identifying the good with pleasure is to prefer a life suitable for beasts. The theological utilitarians had the option of grounding their pursuit of happiness in the will of God; the hedonistic utilitarians needed a different defense. Mill’s approach is to argue that the pleasures of the intellect are intrinsically superior to physical pleasures. Few human creatures would consent to be changed into any of the lower animals, for a promise of the fullest allowance of a beasts pleasures; no intelligent human being would consent to be a fool, no instructed person would be an ignoramus, no person of feeling and conscience would be selfish and base, even though they should be persuaded that the fool, the dunce, or the rascal is better satisfied with his lot than they are with theirs†¦ A being of higher faculties requires more to make him happy, is capable probably of more acute suffering, and is certainly accessible to it at more points, than one of an inferior type; but in spite of these liabilities, he can never really wish to sink into what he feels to be a lower grade of existence†¦ It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied. And if the fool, or the pig, are of a different opinion, it is because they only know their own side of the question†¦ [31] Mill argues that if people who are â€Å"competently acquainted† with two pleasures show a decided preference for one even if it be accompanied by more discontent and â€Å"would not resign it for any quantity of the other† then it is legitimate to regard that pleasure as being superior in quality. Mill recognises that these ‘competent judges’ will not always agree, in which case the judgment of the majority is to be accepted as final. Mill also acknowledges that â€Å"many who are capable of the higher pleasures, occasionally, under the influence of temptation, postpone them to the Utilitarianism lower. But this is quite compatible with a full appreciation of the intrinsic superiority of the higher. † Mill says that this appeal to those who have experienced the relevant pleasures is no different to what must happen when assessing the quantity of pleasure for there is no other way of measuring â€Å"the acutest of two pains, or the intensest of two pleasurable sensations. † Mills proof of the principle of utility In Chapter Four of Utilitarianism Mill considers what proof can be given for the Principle of Utility. He says’ â€Å" The only proof capable of being given that an object is visible, is that people actually see it. The only proof that a sound is audible, is that people hear it In like manner, I apprehend, the sole evidence it is possible to produce that anything is desirable, is that people do actually desire it†¦ No reason can be given why the general happiness is desirable, except that each person, so far as he believes it to be attainable, desires his own happiness†¦ we have not only all the proof which the case admits of, but all which it is possible to require, that happiness is a good: that each persons happiness is a good to that person, and the general happiness, therefore, a good to the aggregate of all persons. †[32] It is usual[33] to say that Mill is committing a number of fallacies. He is accused of committing the naturalistic fallacy, because he is trying to deduce what people ought to do from what they do in fact do; the fallacy of equivocation, because he moves from the fact that something is desirable(1), i. e. is capable of being desired, to the claim that it is desirable(2), i. e.that it ought to be desired; and the fallacy of composition, because the fact that people desire their own happiness does not imply that the aggregate of all persons will desire the general happiness. Hall[34] and Popkin[35] defend Mill against this accusation pointing out that he begins Chapter Four by asserting that â€Å"that questions of ultimate ends do not admit of proof, in the ordinary acceptation of the term† and that this is â€Å"common to all first principles. † According to Hall and Popkin, therefore, Mill does not attempt to â€Å"establish that what people do desire is desirable but merely attempts to make the principles acceptable. †[33] The type of â€Å"proof† Mill is offering consists only of some considerations which, Mill thought, might induce an honest and reasonable man to accept utilitarianism. [33] Having claimed that people do, in fact, desire happiness Mill now has to show that it is the only thing they desire. Mill anticipates the objection that people desire other things such as virtue. He argues that whilst people might start desiring virtue as a means to happiness, eventually, it becomes part of someone’s happiness and is then desired as an end in itself. The principle of utility does not mean that any given pleasure, as music, for instance, or any given exemption from pain, as for example health, are to be looked upon as means to a collective something termed happiness, and to be desired on that account. They are desired and desirable in and for themselves; besides being means, they are a part of the end. Virtue, according to the utilitarian doctrine, is not naturally and originally part of the end, but it is capable of becoming so; and in those who love it disinterestedly it has become so, and is desired and cherished, not as a means to happiness, but as a part of their happiness. [36] 5 Utilitarianism 6 Twentieth century developments Ideal Utilitarianism The description Ideal Utilitarianism was first used by Hastings Rashdall in The Theory of Good and Evil (1907) but is more often associated with G. E. Moore. In Ethics (1912) Moore rejected a purely hedonistic utilitarianism and argued that there is a range of values that might be maximized. Moore’s strategy was to show that it is intuitively implausible that pleasure is the sole measure of what is good. He says that such an assumption, â€Å" involves our saying, for instance, that a world in which absolutely nothing except pleasure existed—no knowledge, no love, no enjoyment of beauty, no moral qualities—must yet be intrinsically better—better worth creating—provided only the total quantity of pleasure in it were the least bit greater, than one in which all these things existed as well as pleasure. † â€Å"It involves our saying that, even if the total quantity of pleasure in each was exactly equal, yet the fact that all the beings in the one possessed in addition knowledge of many different kinds and a full appreciation of all that was beautiful or worthy of love in their world, whereas none of the beings in the other possessed any of these things, would give us no reason whatever for preferring the former to the latter. †[37] Moore admits that it is impossible to prove the case either way but believed that it was intuitively obvious that even if the amount of pleasure stayed the same a world that contained such things as beauty and love would be a better world. He adds that if anybody took the contrary view then â€Å"I think it is self-evident that he would be wrong. †[37] Act and rule utilitarianism In the mid-twentieth century a number of philosophers focused on the place of rules in utilitarian thinking. [38] It was already accepted that it is necessary to use rules to help you choose the right action because the problems of calculating the consequences on each and every occasion would almost certainly result in you frequently choosing something less than the best course of action. Paley had justified the use of rules and Mill says, â€Å"It is truly a whimsical supposition that, if mankind were agreed in considering utility to be the test of morality, they would remain without any agreement as to what is useful, and would take no measures for having their notions on the subject taught to the young, and enforced by law and opinion†¦ to consider the rules of morality as improvable, is one thing; to pass over the intermediate generalisations entirely, and endeavour to test each individual action directly by the first principle, is another†¦ The proposition that happiness is the end and aim of morality, does not mean that no road ought to be laid down to that goal†¦ Nobody argues that the art of navigation is not founded on astronomy, because sailors cannot wait to calculate the Nautical Almanack. Being rational creatures, they go to sea with it ready calculated; and all rational creatures go out upon the sea of life with their minds made up on the common questions of right and wrong. †[39] However, rule utilitarianism proposes a more central role for rules that was thought to rescue the theory from some of its more devastating criticisms, particularly problems to do with justice and promise keeping. Throughout the 1950s and 1960s articles were published both for and against the new form of utilitarianism and through this debate the theory we now call rule utilitarianism was created. In an introduction to an anthology of these articles the editor was able to say, â€Å"The development of this theory was a dialectical process of formulation, criticism, reply and reformulation; the record of this process well illustrates the co-operative development of a philosophical theory. †[40] Smart[41] and McCloskey[42] initially used the terms extreme and restricted utilitarianism but eventually everyone settled on the terms act and rule utilitarianism. The essential difference is in what determines whether or not an action is the right action. Act utilitarianism maintains that an action is right if it maximises utility; rule utilitarianism maintains that an action is right if it Utilitarianism conforms to a rule that maximises utility. In 1953 Urmson published an influential article[43] arguing that Mill justified rules on utilitarian principles. From then on articles have debated this interpretation of Mill. In all probability it was not a distinction that Mill was particularly trying to make and so the evidence in his writing is inevitably mixed. In 1977 a collection of Mill’s writing was published which included a letter in which he said: â€Å"I agree with you that the right way of testing actions by their consequences, is to test them by the natural consequences of the particular action, and not by those which would follow if everyone did the same. But, for the most part, the consideration of what would happen if everyone did the same, is the only means we have of discovering the tendency of the act in the particular case. †[44] This seems to tip the balance in favour of saying that Mill is best classified as an act utilitarian. Some school level textbooks and at least one UK examination board[45] make a further distinction between strong and weak rule utilitarianism. However, it is not clear that this distinction is made in the academic literature. It has been argued that rule utilitarianism collapses into act utilitarianism, because for any given rule, in the case where breaking the rule produces more utility, the rule can be refined by the addition of a sub-rule that handles cases like the exception. [46] This process holds for all cases of exceptions, and so the ‘rules’ have as many ‘sub-rules’ as there are exceptional cases, which, in the end, makes an agent seek out whatever outcome produces the maximum utility. [47] 7 Two-level Utilitarianism In Principles (1973)[48] R. M. Hare accepts that rule utilitarianism collapses into act utilitarianism but claims that this is a result of allowing the rules to be as specific and un-general as we please. He argues that one of the main reasons for introducing rule utilitarianism was to do justice to the general rules that people need for moral education and character development and he proposes that â€Å"a difference between act-utilitarianism and rule-utilitarianism can be introduced by limiting the specificity of the rules, i. e. , by increasing their generality. †[49] This distinction between a ‘specific rule utilitarianism’ (which collapses into act utilitarianism) and ‘general rule utilitarianism’ forms the basis of Hare’s two-level utilitarianism. When we are ‘playing God or the ideal observer’ we use the specific form and we will need to do this when we are deciding what general principles to teach and follow. When we are ‘inculcating’ or in situations where the biases of our human nature are likely to prevent us doing the calculations properly, then we should use the more general rule utilitarianism. Hare argues that in practice, most of the time, we should be following the general principles: â€Å"One ought to abide by the general principles whose general inculcation is for the best; harm is more likely to come, in actual moral situations, from questioning these rules than from sticking to them, unless the situations are very extra-ordinary; the results of sophisticated felicific calculations are not likely, human nature and human ignorance being what they are, to lead to the greatest utility. †[50] In Moral Thinking (1981) Hare illustrated the two extremes. The archangel is the hypothetical person who has perfect knowledge of the situation and no personal biases or weaknesses and always uses critical moral thinking to decide the right thing to do; the ‘prole’ is the hypothetical person who is completely incapable of critical thinking and uses nothing but intuitive moral thinking and, of necessity, has to follow the general moral rules they have been taught or learned through imitation. [51] It is not that some people are archangels and others proles but rather â€Å"we all share the characteristics of both to limited and varying degrees and at different times. †[51] Hare does not specify when we should think more like an archangel and more like a prole as this will, in any case, vary from person to person. However, the critical moral thinking underpins and informs the more intuitive moral thinking. It is responsible for formulating and, if necessary, reformulating the general moral rules. We also switch to critical thinking when trying to deal with unusual situations or in cases where the intuitive moral rules give Utilitarianism conflicting advice. 8 Preference utilitarianism Preference utilitarianism was first put forward in 1977 by John Harsanyi in Morality and the theory of rational behaviour[52] but it is more commonly associated with R. M. Hare,[51] Peter Singer[53] and Richard Brandt. [54] Harsanyi claimed that his theory is indebted to Adam Smith, who equated the moral point of view with that of an impartial but sympathetic observer; to Kant who insisted on the criterion of universality and which may also be described as a criterion of reciprocity; to the classical utilitarians who made maximising social utility the basic criterion of morality; and to ‘the modern theory of rational behaviour under risk and uncertainty, usually described as Bayesian decision theory’. [55] Harsanyi rejects hedonistic utilitarianism as being dependent on an outdated psychology saying that it is far from obvious that everything we do is motivated by a desire to maximise pleasure and minimise pain. He also rejects ideal utilitarianism because â€Å"it is certainly not true as an empirical observation that people’s only purpose in life is to have ‘mental states of intrinsic worth’. †[56] According to Harsanyi, â€Å"preference utilitarianism is the only form of utilitarianism consistent with the important philosophical principle of preference autonomy. By this I mean the principle that, in deciding what is good and what is bad for a given individual, the ultimate criterion can only be his own wants and his own preferences. †[57] Harsanyi adds two caveats. People sometimes have irrational preferences. To deal with this Harsanyi distinguishes between ‘manifest’ preferences and ‘true’ preferences. The former are those â€Å"manifested by his observed behaviour, including preferences possibly based on erroneous factual beliefs, or on careless logical analysis, or on strong emotions that at the moment greatly hinder rational choice† whereas the latter are â€Å"the preferences he would have if he had all the relevant factual information, always reasoned with the greatest possible care, and were in a state of mind most conducive to rational choice. †[57] It is the latter that preference utilitarianism tries to satisfy. The second caveat is that antisocial preferences such as sadism, envy and resentment have to be excluded. Harsanyi achieves this by claiming that such preferences partially exclude those people from the moral community. â€Å"Utilitarian ethics makes all of us members of the same moral community. A person displaying ill will toward others does remain a member of this community, but not with his whole personality. That part of his personality that harbours these hostile antisocial feelings must be excluded from membership, and has no claim for a hearing when it comes to defining our concept of social utility. †[58] More varieties of utilitarianism Negative utilitarianism In The Open Society and its Enemies (1945), Karl Popper argued that the principle maximize pleasure should be replaced by minimize pain. He thought â€Å"it is not only impossible but very dangerous to attempt to maximize the pleasure or the happiness of the people, since such an attempt must lead to totalitarianism. †[59] He claimed that, â€Å"there is, from the ethical point of view, no symmetry between suffering and happiness, or between pain and pleasure†¦ In my opinion human suffering makes a direct moral appeal, namely, the appeal for help, while there is no similar call to increase the happiness of a man who is doing well anyway. A further criticism of the Utilitarian formula ‘Maximize pleasure’ is that it assumes a continuous pleasure-pain scale which allows us to treat degrees of pain as negative degrees of pleasure. But, from the moral point of view, pain cannot be outweighed by pleasure, and especially not one man’s pain by another man’s pleasure. Instead of the greatest happiness for the greatest number, one should demand, more modestly, the least amount of avoidable suffering for all †[60] Utilitarianism The actual term Negative Utilitarianism was introduced by R. N. Smart as the title to his 1958 reply to Popper[61] in which he argued that the principle would entail seeking the quickest and least painful method of killing the entirety of humanity. â€Å"Suppose that a ruler controls a weapon capable of instantly and painlessly destroying the human race. Now it is empirically certain that there would be some suffering before all those alive on any proposed destruction day were to die in the natural course of events. Consequently the use of the weapon is bound to diminish suffering, and would be the rulers duty on NU grounds. †[62] Negative utilitarianism would seem to call.

Directing A New Production Of An Inspector Calls by J. B. Priestly :: English Literature

Directing A New Production Of An Inspector Calls by J. B. Priestly, With Special Reference To Act Two, Page 33 (in Heinemann Plays An Inspector Calls), And The Characters Of The Inspector And Mrs. Birling The two characters that I have chosen - the in The two characters that I have chosen from the play, 'An Inspector Calls', are the Inspector and Mrs. Birling. I chose these characters because they have very contrasting personalities. The Inspector is called 'Goole', which symbolises a ghoul and reflects on his personality. He is very probing when he asks the family questions and obviously has experience with 'interrogating' people. He is very direct and quite blunt when he is questioning the Birling family. In the BBC video version of the play, it was quite obvious that the Inspector was not a normal man as soon as he entered the room. This may have been helped by dramatic music, but it was also evident in the play. "The Inspector enters, and Edna goes, closing the door after her. The Inspector need not be a big man but he creates at once an impression of massiveness, solidity and purposefullyà ¢Ã¢â€š ¬Ã‚ ¦ He speaks carefully, weightily, and has a disconcerting habit of looking hard at the person he addresses before actually speaking." As soon as the Inspector enters the room, the other characters are immediately aware of this "impression of massiveness". In the BBC video the Inspector was quite an old man and he looked feeble in a way, but he still created this effect when he spoke to the other characters. He seems to have a gift to be able to make people feel uncomfortable and guilty when he wants. "INSPECTOR: 'That's more or less what I was thinking earlier tonight, when I was in the infirmary looking at what was left of Eva Smith. A nice little promising life there, I thought, and a nasty mess somebody's made of it.' BIRLING looks as if he is about to make some retort, then thinks better of it, and goes out, closing the door sharply behind him. GERALD and ERIC exchange uneasy glances. The INSPECTOR ignores them." This is a particularly good quote because it shows the Inspector's way of speaking and the character's reactions to him. It seems that Mr Birling cannot even confront the Inspector and has to leave the room, even though Mr Birling was Lord Mayor which gives him authority over a Police Inspector, and is of a higher class than the Inspector, which should give him confidence. Mrs Birling is the quiet wife of the successful owner of Birling and Co. She is a very high-class lady who could be described as 'posh'.

Texting, Bad or Good

When it comes to texting, people either love it, hate it, or just don’t even try because they may feel that they are â€Å"too old for that young people stuff†. Some people will promote it as one of the easiest ways to communicate or consider it a waste of time and murderous to the English language. I, for one, consider it a blessing and a curse. I can see both sides of the subject. I do agree that people shouldn’t text in some situations or places where it is considered rude, dangerous, or where it would take away from the human interaction that people need to mentally survive. Some may argue that with the rise of texting, it has hindered our grammar, the way we interact with others, and possibly our business relations. I used to be a cashier at a grocery store, and from a personal point of view, when the customers were on their cell phone, it made my job as a cashier rough to do. When that happens, the person isn't paying attention because they are busy texting or talking to someone on their phone. It made the job difficult because you were trying to get their attention for a payment method and sometimes had to repeat yourself two or three times. Then, other customers waiting get impatient and look at you like you aren’t doing your job in a speedy fashion. On the other hand, texting can be great and beneficial in some situations. I’ve been in some situations where it was easier to send a text message. At my church I either play the piano or I’m in the sound booth doing the Media for service. From the sound booth to the platform, it’s at least one hundred feet or more. There have been occasions where people on the platform and sound booth needed to tell each other something about the sound or some other situation. It was easier and faster to send a text message to each other rather than trying to read facial expressions or hand signals. All in all, texting is what you make of it. There are some situations in which you need to have respect and not text, such as classrooms, church, and driving in your automobile for example. The thing to do is use common sense and think, â€Å"Is this safe? Is this respectful to others? If I were teaching, would I be okay with people’s attention being divided? † Most of all, we need to just use our brain and use moderation. We can survive without our phones. Our society survived for hundreds of years without mobile devices. I’m pretty sure we could too if we had to.

Orthogonal Frequency Division Multiplexing and Multi-Carrier Code Division Multiple Access

CHAPTER – 1Introduction1.1 OverviewThe involvement for wireless communications disposals has developed gigantically. In malice of the fact that the agreement of 3rd coevals cellular model has been slower than was ab initio expected, scientists are now analyzing 4th coevals cellular systems. These models will convey at much higher rates than the echt 2G models, and even 3G models, in an of all time jammed frequence spectrum. The indispensable aim of next-generation radio systems ( 4G ) won’t merely be the familiarity of new inventions with spread the demand for higher information rates and new services, to boot the incorporation of bing progresss in a typical phase. The scheme of multi-carrier transmittal has late been having broad involvement, peculiarly for high informations rate broadcast applications. The cardinal points of multi-carrier transmittal are its strength in frequence selective attenuation channels and specifically, the reduced signal processing complexnes s by equalisation in the frequence sphere. Figure 1.1: Time variant multipath extension Signals in wireless communicating state of affairss are impaired by melting and multipath hold spread. This prompts a corruptness of the general executing of the model. Henceforth, a few techniques are accessible to relieve these damages and fulfill the expanding demands. Figure 1.1 demonstrates an illustration of clip variant multipath extension. A considerable step of involvement has been placed in transition techniques like Orthogonal Frequency Division Multiplexing ( OFDM ) and Code Division Multiple Access ( CDMA ) . Multiple entree strategies based on a combination of codification division and OFDM techniques have already proven to be strong campaigners for future 4G systems. A major outfall of the higher coevals radio systems is spectral efficiency. In this study, we concentrate on Multicarrier Code-Division Multiple Access ( MCCDMA ) , a fresh digital transition and multi entree strategy. It is a promising attack to the challenge of supplying high informations rate radio communicating. MC-CDMA combines the benefits of CDMA with the natural hardiness to frequency selectivity offered by OFDM. It can be interpreted as CDMA with the distributing taking topographic point in the frequence instead than temporal sphere. Multicarrier CDMA is merger of two different techniques:Orthogonal Frequency Division Multiplexing ( OFDM )Code Division Multiple Access ( CDMA )1.2 Communication SystemCommunication is a manner of conveying information, ’ Technology alterations, but communicating lasts’ ; the handiness of communicating engineerings has made a great impact on human lives. When we communicate, we are sharing information. This sharing can be local or distant. While distant communicating takes topographic point over a distance, the term â€Å"telecommunication† includes telephone and telecasting, means communicating at a distance ( tele is Grecian for â€Å"far† ) Telecommunications can therefore grouped into two -voice & A ; informations. Three cardinal faculties that comprise a full communicating channel: The Sender – A sender encodes the message in a linguistic communication that can be understood by the receiving system.The Receiver –decodes the message.The Medium – Air, Cu wires, optical fibre. These carry the message across from the transmitter to the receiving system. Figure 1.2: Communication system Telecommunication systems have now made it possible to pass on with virtually anyone at any clip. Early telegraph and telephone system used Cu wire to transport signals over the earth’ surface and across oceans and high frequence ( HF ) wireless, besides normally called shortwave wireless, made possible intercontinental telephone links. But now there is different types of communicating strategy. They are following:Telephone SystemCellular SystemsPacket Data SystemsSatellite SystemsMicrowave SystemsFiber Optic SystemsEvery communicating system has its ain frequence scope, system, capacity, application execution cost. On the footing of transmittal system there are two types of communicating systemWired communicating systemWireless communicating system1.2.1 Wireless CommunicationIt is the transportation of information over a distance without the usage of electrical music directors or â€Å"wires† The distances involved may be short agencies few metres as in telecasting remote control or long like 1000s or 1000000s of kilometres for wireless communications. When the scene is clear, the period is frequently shortened to â€Å"wireless† . Wireless communicating is by and large considered to be a subdivision of telecommunications. The term â€Å"wireless† has become a generic and across-the-board word used to depict communications in which electromagnetic moving ridges or RF ( instead than some signifier of wire ) carries a signal over portion or the full communicating way.1.2.2 Previous Work on Wireless SystemJagadish Chandra Bose has been credited with the innovation of the first radio sensing device and the find of millimetre length electromagnetic moving ridges. David E. Hughes, eight old ages before Hertz’s investigates, induced electromagnetic moving ridges in a signaling system. Hughes base on balls on Morse codification by an initiation device. In 1878, Hughes’s initiation transmittal strategy utilized a â€Å"clockwork transmitter† to convey signals. In 1885, T. A. Edison used a vibrator magnet for initiation transmittal. In 1888, Edison set up a theoretical account of signaling on the Lehigh Valley Railroad. In the history of radio engineering, the presentation of the theory of electromagnetic moving ridges by Heinrich Rudolf Hertz in 1888 was of import. The theories of electromagnetic moving ridges were predicted from the research of James Clerk Maxwell and Michael Faraday. Hertz established that electromagnetic moving ridges could be transmitted and caused to go through infinite in consecutive lines and that they were able to be received by an investigational tool. The research was non followed up by Hertz. The applied utilizations of the radio communicating and remote control engineering were implemented by Nikola Tesla.1.3 Drawbacks of Communication SystemCommunication system has some restriction. Bandwidth and Noise restriction is portion of the communicating system. Bandwidth is merely a step of frequence scope. It is easy to see that the bandwidth we define here is closely related to the sum of informations you can convey within it, therefore the more infinite in the frequence spectrum, the more informations you can suit in at a given minute. In a communications system deficiency of bandwidth means deficiency of throughput of apprehensible informations. So that Bandwidth restriction means curtailing the measure of information transmitted from transmitter to receiver each 2nd. The consequences of which are the debasement in the quality of information arrives. Noise will besides impact intelligibility. In an electronic device such as an operational amplifier so there is such a thing known as a addition bandwidth merchandise, in other words how fast can the end product respondent to the input and how much crud ( noise ) is added in the procedure. Thermal noise is besides a topic and Boltzmann’s changeless K finds its manner into the figure of equations. The noise is so important, a assortment of steps have been developed to quantify the consequence of noise in a communications system There is another restriction of communicating is melting. Fading is the fluctuation happened in standard signal strength at the receiving system that is, any arbitrary divergence in the standard signal can be named as attenuation. However the microwave signal travel in the medium due to different parametric quantities there is a decrease in signal strength.1.4 Multiple Access MethodsA limited sum of bandwidth is allocated for radio services. A wireless t heoretical account is compulsory to suit as many users as possible by efficaciously apportion the bandwidth. Therefore, in the field of communications, the word multiple entree could be chiseled as a manner of leting multiple users to concurrently administer the finite bandwidth with smallest likely debasement in the public presentation of the system. There are a figure of methods demoing how the multiple accessing can be attained. There are four basic strategies:Frequency Division Multiple Access ( FDMA ) .Time Division Multiple Access ( TDMA ) .Code Division Multiple Access ( CDMA )Space Division Multiple Access ( SDMA )These techniques can be grouped as wideband and narrowband systems, subjected to how the available bandwidth is allocated to the users. The duplexing method of a multiple entree system is normally described along with the peculiar multiple entree system, as shown in the cases that follow. Narrowband Systems:The term narrowband is used to associate the bandwidth of a individual channel to the expected coherency bandwidth of the channel. In a narrowband multiple entree strategy, the unfilled wireless spectrum is separated into a big figure of narrowband channels. The channels are by and large operated utilizing FDD. To diminish intervention between contrary and frontward links on each channel, the frequence separation is made every bit great as possible within the frequence spectrum, while still allowing low-priced duplexers and a common transceiver aerial to be used in each subscriber terminal. Wideband Systems:In wideband theoretical accounts, transmittal bandwidth of a individual channel is much larger than the coherency bandwidth of the channel. Therefore, multi-path attenuation does non greatly vary the standard signal power within a wideband channel and the frequence selective slices go on in merely a little fraction of the signal bandwidth at any juncture of clip. In wideband multiple entree theoretical accounts a big figure of senders are allowed to convey on the same channel.1.5 Requirement of MC-CDMAThree major multiple entree strategies exist: frequence division multiple entree ( FDMA ) , clip division multiple entree ( TDMA ) and code division multiple entree ( CDMA ) [ 1 ] . In the undermentioned subdivisions, the advantages and disadvantages of these techniques will be studied, and the necessity for multicarrier codification division entree ( MC-CDMA ) will be discussed.1.5.1 Frequency Division Multiple Access ( FDMA ) Figure 1.3: Frequency division multiple entree ( FDMA ) [ 1 ] Frequency division multiple entree ( FDMA ) was the first multiple entree technique, developed in the early 1900s [ 2 ] . With FDMA, the entire frequence bandwidth is divided into frequence channels that are assigned to each user for good, ensuing in multiple user signals that are both spectrally separated and at the same time transmitted and received. This has been diagrammatically signified in Figure 1.3. The FDMA systems require a comparatively simple algorithm and execution compared to TDMA and CDMA [ 1 ] , but there are several drawbacks. First, due to the lasting assignment of FDMA channels, fresh channels can non be utilized by other clients, the effect of which is the abuse of the communicating resources. Second, nonlinearities in the power amplifier can do signal spreading in the frequence sphere, doing inter-channel intervention ( ICI ) in other FDMA channels. Finally, the capacity of an FDMA system is limited by Thursday vitamin E figure of channels available.1.5.2 Time Division Multiple Access ( TDMA ) Figure 1.4: Time division multiple entree ( TDMA ) [ 1 ] Time division multiple entree ( TDMA ) has been developed with a similar thought to FDMA, but with TDMA, multiple user signals are separated in the clip sphere instead than the frequence sphere. Figure 1.4 shows a TDMA system with the transmittal clip divided into a figure of cyclically reiterating clip slots that can be assigned to single users, leting all users entree to all of the available bandwidth. Compared to FDMA systems, TDMA systems offer more flexibleness in the assignment of clip slots whereby different Numberss of clip slots can be allocated to different users depending on the service needed. In add-on, because TDMA users can convey signals merely in their ain clip slots, the transmittal of TDMA signal is noncontiguous and occurs in explosions, ensuing in less battery power ingestion. But, the TDMA signal needs a big synchronism operating expense due to its non-continuous transmittal. Inter-symbol intervention ( ISI ) , caused by multipath extension, is besides a serious bug for TDMA, particularly durin g high informations rate transmittals.1.5.3 Code Division Multiple Access ( CDMA )In the last 10 old ages, codification division multiple entree ( CDMA ) has been developed to get the better of the disadvantages of other multiple entree techniques such as TDMA and FDMA [ 3 ] . Figure 1.5: Code division multiple entree ( CDMA ) [ 1 ] Figure 1.5 demonstrates multiple CDMA user signals that are separated by distributing sequences. In specific, all user signal is spread utilizing a pseudorandom sequence which is extraneous to the sequence of other users. As a consequence, merely the intended user-receiver can despread and have the information right ; other users on the system perceive the signal as noise, ensuing in multiple user signals that can be transmitted within the same bandwidth at the same time. The chief advantage with CDMA is that the system capacity is limited merely by the sum of intervention ; with a lower degree of intervention the system can back up a higher figure of users [ 1 ] . CDMA systems are besides robust to narrow set jamming as the receiver signal can distribute the jamming signal’s energy over the full bandwidth doing it undistinguished in comparing to the signal itself [ 2 ] . If the spreading sequence is absolutely extraneous, it is possible to convey multiple CDMA signals without presenting multiple entree intervention ( MAI ) during synchronal transmittal [ 3 ] Assorted types of CDMA such as direct-sequence CDMA ( DS-CDMA ) and wideband CDMA ( W-CDMA ) , have been utilised and advanced in both 2G and 3G systems similar to CDMA One ( IS-95 ) , UMTS and CDMA2000 [ 4 ] . These techniques are considered to be single-carrier CDMA systems. Unfortunately when traveling into the 4th coevals of wireless communicating systems ( 4G ) , in which information is transmitted at a rate every bit high as 1 Giga bits-per-second ( bits per second ) [ 5 ] , single-carrier CDMA theoretical accounts are non appropriate. This is for the grounds as fallowWith high informations rates the symbol continuance will go sawed-off, ensuing in the channel hold spread transcending the symbol continuance doing ISI [ 6 ] .When informations rate goes beyond a 100 Mega bits per second, it turn out to be a hard undertaking to synchronise, as the information is sequenced at high velocities [ 7 ] .Because of the multipath extension, signal energy is distributed in the clip sphere: in single-carrier CDMA systems such as DS-CDMA, RAKE receiving systems are frequently used to unite the multipath signals. However, non all waies of signals can be successfully received. If the figure of fingers in the RAKE receiving system is less than the figure of resolvable waies, some of the standard signal energy can non be combined, therefore a part of the signal energy is lost [ 8 ] . But if the figure of fingers in the RAKE receiving system is more than the figure of resolvable waies, noise will be improved.Therefore an Orthodox single-carrier CDMA such as DS-CDMA is non practical for 4G systems where a high information rate is required.1.5.4 Orthogonal Frequency Division Multiplexing ( OFDM )Orthogonal frequence division multiplexing ( OFDM ) proposed in [ 9 ] has the ability to back up higher information rate transmittal. When utilizing OFDM, the channel bandwidth is divided into a figure of equal bandwidth bomber channels, with each bomber channel using a subcarrier to convey a information symbol. The frequence separation of next subcarriers is chosen to be the opposite of the symbol continuance, ensuing in all the subcarriers being extraneous to one another over one symbol interval. Therefore, OFDM method can convey a immense figure of different informations symbols over multiple subcarriers at the same time, enabling this technique to back up a higher information rate transmittal. In add-on the bandwidth of each bomber channel is designed to be so narrow that the frequence features of each bomber channel are changeless, creative activity OFDM signals healthy to frequency selective attenuation [ 10 ] . The other advantage of OFDM is that the signal can be easy and expeditiously modulated and demodulated utilizing fast Fourier transform ( FFT ) devices [ 11 ] . As FFT can be easy implemented, the receiving system complexness does non increase well while transmittal rate can be mostly increased. Despite all these advantages, OFDM still has some drawbacks due to its execution of multicarrier transition. OFDM suffers a high peak-to-average power ratio that occurs when all the signals in the subcarriers are added constructively [ 12, 13 ] . This consequences in the impregnation of the power elaboration at the sender, triping inter-modulation deformation. OFDM is really sensitive to frequency offset, as the graph of the subcarriers is overlapping [ 14, 15 ] . Any frequence offset can do to ICI, which put forward that OFDM requires a high grade of synchronism of subcarriers. Besides, the conventional OFDM systems can back up merely a individual client, demanding the demand for multicarrier codification divi Zion multiple entree ( MC-CDMA ) .1.5.5 Multicarrier Code Division Multiple Access ( MC-CDMA )Based on the combination of OFDM and DS-CDMA, a multicarrier codification division multiple entree ( MC-CDMA ) is proposed [ 16 ] . Unlike DS-CDMA, which spreads the original informat ion watercourse into the clip sphere, MC-CDMA spreads the original information watercourse into the frequence sphere by ab initio change overing the input informations watercourse from consecutive to parallel so multiplying this watercourse by the distributing french friess in different OFDM subcarriers, the consequence of which is MC-CDMA signal which takes on the advantages of both DS-CDMA and OFDM. The advantages of MC-CDMA are:The capacity is interference limited [ 17 ] and any techniques that cut down intervention are capable of increasing the capacity of MC-CDMA.The signal is robust to frequency selective attenuation and can back up high informations rate transmittal.Bandwidth is used more expeditiously as the spectra of subcarrier convergence [ 18 ] .Since the standard signal is combined in the frequence sphere, an MC-CDMA receiving system can use all the standard signal energy scattered in the frequence sphere [ 19 ] . This is a important advantage over DS-CDMA, where portio n of the signal energy can be lost due to deficient figure of fingers in the RAKE receiving system.The sender and receiving system signals can be implemented utilizing FFT, which does non increase the grade of complexness.1.6 ObjectiveThe chief aim of this thesis is to develop an attack to minimise the consequence of multipath attenuation in Rayleigh attenuation environment utilizing Multicarrier CDMA ( MC-CDMA ) with RAKE receiving system and different uniting strategies viz ; Equal Gain Combining ( EGC ) , Maximal Ratio Combining ( MRC ) , Zero-Forcing ( Z-F ) and Minimal Mean Square Error ( MMSE ) Equalization.1.7 Outline Of DissertationChapter-1 Introduction: This chapter is divided in six parts ; overview, communicating system, drawbacks of communicating system, multiple entree methods, demand of MC-CDMA, and eventually nonsubjective is explained. Chapter-2 Orthogonal Frequency Division Multiplexing: This chapter gives a elaborate account about overview of OFDM, guard interval, perpendicularity, mathematical analysis of OFDM and fourier transform. Chapter-3 Multi-Carrier Code Division Multiple Access: This chapter gives elaborate information about overview of multi-carrier transition, channel synchronism and appraisal in multi-carrier systems, overview of CDMA, rudimentss of MC-CDMA and channel theoretical accounts. Chapter-4 Literature Review: This chapter gives elaborate information about old work on Multi Carrier Code Division Multiple Access. It besides elaborate the job definition sing the research work. Chapter-5Proposed Methodology: This chapter explains the proposed methodological analysis which is used in this undertaking.

This Fall Apart Essays - African Writers Series, Free Essays This Fall Apart ESSAY ON THINGS FALL APART Things fall apart tells a story of an African tribe and it's cultures. It tells the story of the life of a man by the name of Okonkwo, by his lifelong friend, Obierika. Okonkwo, a well-respected member of his village, had an undying desire to be manly at all times. He was a father and a husband of three wives and worked very hard to support his family; he began doing so at a very young age. Under no circumstances would he ever warrant the assumption by any man that he was either weak or afraid. The only fear that he did have was that any man think such of him. Okonkwo had a very short, violent temper that was immediately triggered in response to actions that he deemed to be weak of another. Unfortunately, almost every time that Okonkwo let loose his violent temper in his manly way, he brought trouble upon himself, as well as those around him. Though highly respected in his village, Okonkwo was exiled and banished from the village for seven years. This was the result of the murder of a clansman. Although the act was truly accidental during the funeral of an elder in the village, to kill fellow clansmen was not accepted. During the ceremony guns where fired, Okonkwo accidentally fired his gun, killing the son of the dead elder. Since this was done accidentally he was able to return to the village with his family after being banished for seven years. During the seven years of his exile, the Ibo village started to fall apart. The downfall of the Ibo spiritually was the mechanism that triggered the downfall of the Ibo village and it's livelihood. White missionaries emerged on the village bringing with them their Christian religion and beliefs that were totally different from the Ibo people. This was two years after one of their own was killed in the village. Although the collapse was primarily caused by three men, Mr. Brown, Rev. James Smith, and the District Commissioner, it was the passivity of the village (Umuofia), as well as the power of the mission's government that led to the demise of the Ibo way of life. Clearly this strengthened the credibility of the new white men and their religion. Futhermore, a major blow was dealt to the Ibo religion. Christianity provided an answer to the questions' people had about their spirituality: the Ibo religion began to appear to be false by default. The new religion's validity and acceptance, coupled with the void created by the dissolution of the void created by the dissolution of the Ibo spiritually, left the remaining Ibo believers over powered by the Christian converts and their new followers. A final illustration of Okonkwo's rash actions leading suffering for himself and those around him occurs when he hastily kills the head messenger who comes to Umuofia to break up a town meeting. Okonkwo and his fellow villagers came together and were planning to kill the missionaries. The messenger stood up to Okonkwo demanding to get by. Able to speak only two short sentences, Okonkwo furiously assassinated him; taking his machete and cutting off his head. This did not produce a war of any type. The remaining three messengers continued their journey and the villagers never attacked. This brought the ultimate suffering to Okonkwo, who hangs himself, as well as the suffering for the rest of the tribe, who may not bury him and some of whom are brought to the court where Okonkwo and some others had at one time suffered. In concluding I would say that Africans in their traditional beliefs and ethics, are very passionate about what I would consider supernatural, or mystical powers. Some of their beliefs I could accept in a spiritual way but not as a way of living my life. The beating of one's wife is not condoned under any circumstances, and effects the community as a whole. This is regarded as totally unacceptable but not because it happened on the wrong day but because it's morally wrong.

Research proposal - Essay Example Lesser and lesser number of people are willing to spare a dime or a penny for them as days go by. Business establishments frown at the sight of them near their front doors. While there have been scientific studies focusing on beggary and their activities, beggars are generally misunderstood. Amidst, their seeming oblivious perception of the world turning either indifferent or hostile to their plight, beggars have their own untold stories, which this research will attempt to unfold before the world. A better awareness of beggars and their fight for survival, may rally people and organizations to their cause, thus, lesser hostility and greater sympathy, empathy and respect. The eleventh edition of Merriam-Webster’s Collegiate Dictionary defined the noun beggar as â€Å"a person who lives by asking for gifts† (Mish 110). From the early goings of the survey of existing literature, much of the literature and studies on beggary were more of decade-old legal reviews into the unconstitutionality of prohibiting panhandling in cities or states of the US from the New York Law School (Mitchell 697-717), University of Baltimore (Mitchell 291) and other institutions for law studies. One literature investigated the constitutional implications of the ban on begging in the state of California (Walston 547). There were also found substantial and recent scientific literature dealing with beggars. Three of these works are discussed in this proposal. Lee and Farrell (299-324), Smith (par. 1-8) and Lankenau (288-318 ). Lee and Farrell utilized data from two American national surveys to gather information homeless pan-handlers and non-panhandlers and the public perception on pandhandling activities. Findings revealed that the homeless panhandlers are â€Å"more isolated, troubled and disadvantaged† than the homeless non-panhandlers. The study also disclosed that although minority of the homeless

Art - Essay Example It would have been more natural if he had drawn soft boundaries with light pencil. Warhol has very nicely painted the nose giving shades of gray and white color very nicely. It is where he has kept his hand very light giving this feature a very original feel. The sketch is cool overall and the painter has no doubt drawn it with keen observation. I like the way the hair has been drawn and painted giving the man a sober look. The hair is not parted and is very cleverly hiding half of the ear. The collar covering the neck has also been nicely drawn giving a brief description of the man’s satire. Although, the picture is not colorful, yet the sketch is complete in itself and the color tones the painter has used seem enough for this piece of art. It is his great success that he has been able to show what age the man was, how he looked like, and his personality, using a few shades of two to three colors. In this picture, Raymond Johnson has put into abstract the sky and landscape of New Mexico and the picture tells more of his experience with the scene. Johnson was of the view that a masterpiece results from actual experience depicted in the form of painting and what counts is the internal significance of things which is an abstract quality. Something painted in abstract gives it the real life and soul. Johnson has always used two approaches to paint land. First, he would give a deep insight into his mood and experience that he had, and second, he would paint out in abstract everything giving special consideration to their forms and the manner in which they receive and emit light. The picture is a beautiful abstract form of landscape with black clouds hovering over it giving the feel of gloominess and pleasure at the same time. I like the green patches the painter has shown on the landscape and the shades of orange, pink, green and yellow give a very soothing look. The place the pai nter had in his mind must have been a piece of calm and cozy piece of land which
