Conflict of interest Case Study Example | Topics and Well Written Essays - 500 words

Conflict of interest - Case Study Example Most of the cases that are brought to the surface are of corruption, bribery, and money laundering. Despite the fact that these issues are worth concerning, but the conflict of interest that is exhibited by these institutions behind the scene and during interrogation phase is gross and vulgar (Hines & Reserve, 2014). Moreover, these acts not only violate the Charter of Human Rights, but it also disobeys the various international treaties, international law, and etc. Conflict of interest is a phenomenon that deals with the abuse of power, where public rights are compromised in order to obtain private gain. Everywhere all across the government and non-government organization one can find several examples of the officials who abuse their authority and position for obtain personal benefits. Conflict refers to disagreement, this disagreement can be on various levels, for instance it can be on the basis of violation of organization’s policy, it may be a disagreement in principle, or disagreement in practice and etc. Conflict of interest can also be dealt as an act of corruption, because it is the violation of trust, and misuse of a power entrusted to an official on a higher rank who is supposed to use the power for public security instead of personal profit. The case of Captain James CoBell is yet another example of a military official crossing his limits, and using his influence for satisfying his pleasure. CoBell was assigned the command of the fleet readiness commander Mid-Atlantic in 2011. In a press release by Naval Air System Command, quotes the investigation, by Commander, Fleet Readiness Centers "misused his position in using subordinates for personal favors, used abusive language toward his personnel and failed to properly account for personal leave," (Stewart, 2012). However, in response to the charges laid upon him, CoBell said that his tenure as Executive and commanding officer did not have any element

How Consumer Insight Are Shaping Companies in India Essay Example for Free

How Consumer Insight Are Shaping Companies in India Essay Customer is King is an adage that most companies across the globe have embraced. The need to concentrate on customers and be responsive to their demands has long been acknowledged by organizations. However, with globalisation and technological revolution the dynamics of business, the meaning of customer and market knowledge have all undergone a transformation. Today, the customer is the controlling factor in business and to be market-driven, an organisation has to evolve a culture that constantly listens to the customer, analyses competition and has strategies that meet existing, anticipated and even unanticipated needs of the customer. Going one step further, organizations must focus on customer relationship management which has given way to customer knowledge management. Given the international environment and knowledge economy, market and customer intelligence serves as a core competency and a principal source of competitive advantage. Leading by listening Practically every success story in today’s corporate realm reflects how awareness of customer needs shapes competitive business strategy. Let’s look at some examples. Procter Gamble When PG, the largest consumer goods company in the world, chose to offer its products to the lower income customer in developing countries, it had research teams associating with the poorest of homes for weeks. This gave the company valuable insights, which aided the company in creating a range of products that suited the pockets of this segment, enabling it to gain substantial market share. Amazon.com Amazon.com, the first e-retailer of books in the world, attained competitive advantage by emerging as book lovers’ forum where they could also share knowledge. It maintains customer knowledge through services such as book reviews, access to order histories and product recommendations based on preceding orders. Consequently, Amazon has recorded more than 70% repeat orders from its customers. Mahindra Mahindra Mahindra Mahindra’s SUV, Scorpio, has experienced enormous success in domestic and international markets. The positioning of Scorpio as an economy SUV was centered on the findings of extensive market visits and exploration of customer needs. The customer needs and wants ascertained were transformed into product specifications for Scorpio. Customer groups were consulted at every stage of design and product development. Scorpio was designated as the â€Å"Car of the Year† by ‘BBC on Wheels’ shortly after its launch. Indian Railways The amazing transformation of Indian Railways from what was termed as a white elephant to a profit making entity in less than two years has caught the attention of Indian and foreign academic and corporate establishments. This turnaround was not owing to any high-end technology but to a modest information means — the passenger feedback form. Data attained from these forms was analysed to identify customer expectations from the Railways. This was supported by a study of the best railways worldwide, and benchmarking with other transportations such as roadways and airlines. The outcome was a complete renovation of trains, stations and railway services to render them passenger-friendly. Needless to say, customers welcomed this change. The above examples highlight that it is vital to listen to customers for a success marketer-customer relationship, where the customer is not just a beneficiary, but a partner. Effective listening, together with strategic initiatives, can bring about a happily-ever-after end to this association.

Ernest Hemingway :: essays research papers

Hemingway Essay   Ã‚  Ã‚  Ã‚  Ã‚  A good writer’s objective is to say as much as possible as briefly as possible. This enables the thinking about the implications of the word’s presented. Ernest Hemingway explained this idea in his “iceberg'; theory of writing fiction in an interview for Paris Review: “ If it is any use to know it, I always try to write on the principle of the iceberg. There are seven-eighths of it under water for every part that shows.'; In order to expand on the meaning of his plots and characters, Hemingway used symbols and extended meanings to supply the unstated and submerged portion of his stories. The story “ Hills Like White Elephants'; is an excellent example of Hemingway’s “iceberg'; principal with its extensive use of literary symbols.   Ã‚  Ã‚  Ã‚  Ã‚  In Hemingway’s “iceberg'; theory of writing, Hemingway wants readers to “read in-between lines'; and derive the true meaning of the story. To do this, you must interpret the symbolism Hemingway uses.   Ã‚  Ã‚  Ã‚  Ã‚  The story “Hills Like White Elephants'; is about a man and a woman who are at a train station in Madrid, Spain. The woman is pregnant and the man and the woman are discussing whether the woman should have an abortion operation. They have only forty minutes (the time they have to wait for their train to arrive) to make their decision. At the end of the story, the woman is still not certain if she should have the abortion operation.   Ã‚  Ã‚  Ã‚  Ã‚  In “Hills Like White Elephants';, there are many examples of the “iceberg'; theory. One strong example was when the woman, referring to the hills, says,“ They look like white elephants.'; The woman later says, in response to the man’s request of trying to have a fine time,“ All right. I was trying. I said the mountains looked like white elephants. Wasn’t that bright?'; The white elephants in these two statements symbolize the woman’s mythical dreams. The white elephants were just a figment of her imagination. The background and the horizon of the hills represent all the remote possibilities for the resolution of their current problem. Another example of Hemingway’s iceberg theory in the story “Hills Like White Elephants'; is the two sides of the valley; “ The hills across the valley of the Ebro were long and white. On this side there was no shade and no trees and the station was between two lines of rails in the sun.'; The detailed symbolism of the two sides of the valley represent the two characters, the man and the woman.

Jose Rizal’s Family

Jose Rizal's parents, Francisco Mercado Rizal y Alejandro (1818–1898)[8] and Teodora Alonzo y Quintos(1826–1911),[8] were prosperous farmers who were granted lease of a hacienda and an accompanying rice farm by the Dominicans. Rizal was the seventh child of their eleven children namely: Saturnina (1850–1913), Paciano (1851–1930), Narcisa (1852–1939), Olympia (1855–1887), Lucia (1857–1919), Maria (1859–1945), Jose Protasio (1861–1896), Concepcion (1862–1865), Josefa (1865–1945), Trinidad (1868–1951) and Soledad (1870–1929). Rizal was a 9th-generation patrilineal descendant of Domingo Lam-co (Chinese: pinyin: Ke Yinan), a Chinese immigrant entrepreneur who sailed to the Philippines from Jinjiang, Quanzhou in the mid-17th century. [9] Lam-co married Inez de la Rosa, a Sangley native of Luzon. To free his descendants from the Sinophobic animosity of the Spanish authorities, Lam-co changed the surn ame to the Spanish â€Å"Mercado† (market) to indicate their Chinese merchant roots. In 1849, Governor-General Narciso Claveria ordered all native families in the Philippines to choose new surnames from a list of Spanish family names. Jose's father Francisco[8] adopted the surname â€Å"Rizal† (originally Ricial, the green of young growth or green fields), which was suggested to him by a provincial governor, or as Jose had described him, â€Å"a friend of the family†. However, the name change caused confusion in the business affairs of Francisco, most of which were begun under the old name. After a few years, he settled on the name â€Å"Rizal Mercado† as a compromise, but usually just used the original surname â€Å"Mercado†. Upon enrolling at the Ateneo Municipal de Manila, Jose dropped the last three names that make up his full name, at the advice of his brother, Paciano Rizal Mercado, and the Rizal Mercado family, thus rendering his name as â€Å"Jose Protasio Rizal†. Of this, Rizal writes: â€Å"My family never paid much attention [to our second surname Rizal], but now I had to use it, thus giving me the appearance of an illegitimate child! â€Å"[10] This was to enable him to travel freely and disassociate him from his brother, who had gained notoriety with his earlier links with native priests who were sentenced to death as subversives. From early childhood, Jose and Paciano were already advancing unheard-of political ideas of freedom and individual rights which infuriated the authorities. [11][12] Despite the name change, Jose, as â€Å"Rizal† soon distinguishes himself in poetry writing contests, impressing his professors with his facility with Castilian and other foreign languages, and later, in writing essays that are critical of the Spanish historical accounts of the pre-colonial Philippine societies. Indeed, by 1891, the year he finished his sunset, this second surname had become so well known that, as he writes to another friend, â€Å"All my family now carry the name Rizal instead of Mercado because the name Rizal means persecution! Good! I too want to join them and be worthy of this family name†¦ â€Å"[10] Jose became the focal point by which the family became known, at least from the point of view of colonial authorities.

Methodism, the most astonishing eruption in the eighteenth century history of religion, was an anomaly

The eighteenth century is commonly viewed by historians as a period of decline for the Anglican establishment which suffered increasing losses in its authority over local parishes and failing to respond adequately to the changing society of the early industrial age and challenges over the nature of religion and its role in the lives of individuals. In the 1740s, Samuel Wesley and his sons began to preach outside the confines of the Church, advocating a more voluntary approach to religious devotion and encouraging increased involvement of laymen in the work of the parish. Methodism was effectively born out of societies set up to integrate the church into the community, but in carrying voluntarism to its logical conclusion, argues Gilbert, such a movement would naturally come into conflict with the establishment by offering an alternative to the prescribed methods of religious practise and undermining the ministerial authority and organising machinery of the Church. Although the Wesley family were conservative Tories and John Wesley, who was to become the leading Methodist figure, always expressed a keen desire to remain within Anglicanism, he told a inaugural conference in 1744 that Methodism would either leave the whole church or â€Å"be thrust out of it† Whether the Methodists were in essence a radical or conservative group was at the time, and remains a much debated topic. In an essay on Methodism, Dissent and Political Stability2, Gilbert argues that it was in fact both. Methodism was a means of taking a stand against prescribed religion and the status quo of social organisation through the withdrawal of status respect and assertion of freedom. Methodism was in effect a radical means of political and social protest in an era of new ideas and social instability, epitomised abroad by the violent revolutions in France, and yet the movement was unobtrusive in its politics and the moderate nature of this radicalism had a stabilising effect on society, acting as a â€Å"safety valve† that contained tension and helped avoid the polarisation of opinions. Looking at the religious history of other European nations, Methodism is quite the anomaly, a dissenting movement, cast out of the Anglican Church that eventually serves to prop up the traditional order. Weakness in the Anglican establishment dated back to the reformation, which had been a break away from authority from Rome, but had also meant an increase in secular authority over the ecclesiastical, through the judicial courts, some tithe taxes and rights of patronage. Though the clerical influence in national politics and in local parishes was still strong, it was no longer as an independent body, but in conjunction with secular authorities. Loss of influence in the upper echelons of power, with monarchs of differing faith on the throne and the abbots losing their majority in the Lords was coupled with strain on authority in the parishes through lack of adequate funding or dynamism. The demographic boom of the late eighteenth century and the breakdown of the traditional parish based organisation of ancien regime society with the increase in manufacturing towns left many outside the network of pastoral oversight, as Ward notes, this and toleration laws paved the way for eager dissenters to exert influence3. However, the first half of the century is more commonly characterised by a mood of religious apathy. Numbers attending Anglican services were declining, but Gilbert argues, Protestant dissent was also in a state of atrophy in 1740. Looking at statistics, this could be seen as a dramatic turning point in the history of religious dissent, but it must be remembered that after new toleration acts were passed it became necessary for all groups to register, nevertheless, this was a period when old dissenting movements were being surpassed by the new evangelicals, who could serve the community where the Anglican church could no longer cope. Naturally there was a certain discontinuity of dissent, with different traditions declining and growing in different patterns across the country. The chapel movement was one that responded to local needs, in some areas lay societies along evangelical lines were even encouraged by the local clergy, but the most prominent groups inevitably sprang up where the church was least effective and inevitably would become a source of conflict with the establishment. The evangelical revival of the late eighteenth and early nineteenth centuries was above all a popular movement, and with no central driving force, it is difficult to define the limits of the movement. Dissenters within the orthodoxy of the Church had existed before, but a newfound zeal, enthusiastic conversion methods and a more coherent programme now developed into a single, if multiform, religious phenomenon. Although there were divisions between Methodists, Baptists, Congregationalists and Independents, they were not fundamental. All relied on lay preachers and the centrality of village communities to spread their message of voluntary piety, based around the family and spiritual equality, whereby all could receive salvation through faith and good works. Methodism can perhaps be characterised by its system of connexion networks that linked dissenting groups across the country. Wesley had hoped to unite his movement through the Anglican ministers and in 1764 had sent fifty letters appealing for a unity of purpose, but receiving only three replies, realised he would have to unite and organise his followers outside the clergy. The strength of the movement however, was not in a system of alliances, but its dynamism. Methodism was a movement that spread rapidly through expansionist missionary societies, and Wesley's followers breached the movement further away from the church by demanding that its preachers should be able to give communion. A 1793 conference voted that members of a society who were unanimous in their desire to receive the sacrament from their preacher might do so. Ward questions whether this was a case of the preachers following the flock, or the scheming of radical ministers to use the Methodist congregations to spread their radical political ideas. Samuel Bradburn was one such minister who introduced ideas of unbounded liberty and the Rights of Man into his sermons, but he shunned Kilham, an even more defiant political Methodist, casting doubt on any suggestion of a central political aim. In the 1790s, social tensions were reaching boiling point. Evangelical societies attracted dissenters at all social levels, even at court, where many independent politicians, clergymen and intellectuals deserted George III and headed a campaign as a Unitarian group for reforms to free trade and end slavery, believing in free enquiry and social progress. Among the lower social orders there was a backlash against the increasing number of dissenters and riots broke out, prompted by food shortages but also calling for â€Å"Church and King† and were largely unhindered by the clergy and magistrates of the old order. It is important to remember that while the growth of evangelical movements was significant, it still only affected a small proportion of the population, with many remaining ambivalent towards new ideals of piety and man others choosing to remain firmly within the Anglican fold. For some, traditional means of expressing discontent were still favoured. Davidoff sees the Evangelical movement as a largely middle class phenomenon. This was a rapidly expanding social group that needed to form their identity. He argues that a sense of religious belonging was provided by the various evangelical movements became a part of middle class culture and the success of the movement can be credited to its ability to fill this need. Traditional church practise did not involve participation from the lay community, and while the middle classes were a group with little political power, there role was gradually becoming more like that of the traditional gentry, as Lords devolved their duties in a practise of stewardship. Dissenting evangelical groups formed a basis of a middle class community as well as a middle class culture. The religious focus is undeniably meritocratic in tone; that salvation was open to all through their own piety. Davidoff also believes that there was a notion that this piety could give individuals strength to bare hostility from others, as the new middle classes may well have faced in the years of hardship and social tension at the end of the eighteenth century. The central importance of the family crossed denominations, another middle class value. The ideal was of the home as a moral haven from the amoral world of the business market. This haven was created by women, who were viewed as naturally more pious than men. The concepts of masculine and feminine were being transposed into more distinct social roles, each with their own responsibilities. Men were the material providers of the family and women's role was to create a moral home for her husband and children, domestic seclusion was a moral ideal and some serious evangelicals even shunned the pleasures of sport and the theatre in favour of this domesticity. Women did have increased prominence in church life, in some denominations they could even be ministers, but overall, the new movements were still male dominated. In some areas women may even have lost influence, where before they could have performed duties of clerks where necessary, roles were now more often formalised into those that were acceptable for women and those that were not. The evangelical community gave the middle class a forum to profess their beliefs and help to form their own culture and community. Dissenting groups were most prominent in new manufacturing towns and much of their establishment can be seen as benefiting the middle classes. They set up church schools and welfare societies, seeing their community almost s an extension of their family that need to be provided for. Schools were central to the evangelical movement, supporting the middle class love of reading and reflection as alternative entertainments. Indeed it was often the case that the school came before the chapel, as was the case in Bollington, a manufacturing town in the Northwest. Although initially non-denominational, the school soon became dominated by the Methodists. But importantly, the erection of such public buildings was not decided on by the preachers, but went before an appeal to the town, in tune with democratic principals. The practise of the Sunday school was an important means of gaining support among the locals, as many sent their children to work in factories at an early age and this would still give them a chance to learn to read. The work of evangelicals within their communities through charity and education may have stunted working class resentment, but Davidoff asserts that they still tended to stay away from Church. Gilberts sees the evangelicals as targeting the lower echelons of society, corroding the image of the lower orders as simple minded and maybe thus giving cause for concern to the ruling classes, but it is probable that these are two differing views of what was essentially the same social group, seen as the lower orders by contemporaries, but viewed by some historians, in the pattern of social evolution, as the emerging middle classes. The end of the eighteenth and beginning of the nineteenth centuries saw a demographic boom, centred around new manufacturing towns. It was the early years of the industrial age and the changing structure of society had new needs that the state and church could not provide for. Looking abroad for a point of comparison, French society, with its firmly established monarchy and church was thrust into a violent revolution that was to remove both. In England, the less powerful position occupied by the monarchy and church could be seen as perhaps what saved them from a similar fate. Dissenting movements had been allowed to develop that were then to serve as a moderating force. There was much confusion in the late eighteenth century as to Methodists and their significance. The movement grew further and faster than other evangelical societies, and what Smyth called â€Å"Christian godliness without Christian organisation† in 1795 was attacked by others as having too much organisation and followers were subject to too much pastoral oversight, threatening the formation of a radical political force. 5 Indeed, Sidney Pollard and Robert Southerly were of the view that revolution was imminent. With hindsight, historians like Halevy have argued that there was nothing for the state to fear in the rise of Methodism, but contemporary powers would not have been able to see the larger picture of changing society and the development of a middle-class and so the movement may have been forced into its unobtrusive political stance where perhaps more radical beliefs were deep-seated. Jabez Bunting, a radical Methodist figure after the death of Wesley, saw the movement as wide, but not deep. He was relatively apolitical, but was keen to preserve the liberties that Methodism had benefited from in the face of conservative reaction to social tensions and revolution in Europe. But the evangelical revival, viewed with historical hindsight is indeed a political movement, the energies of the chapel communities were a force that resisted to reactionism and later advocated reforms, but after 1850 the dynamism of the movement had dwindled, as the social tensions of the age eased.

10 Last-Minute PSAT Cramming Tips

10 Last-Minute PSAT Cramming Tips SAT / ACT Prep Online Guides and Tips The PSAT is coming up- fast. Test day will be here whether you've been studying or not.For the SAT, I would recommend delaying for a later test date, but that's not really possible with the PSAT. If youhave less than three weeks left, you're going to have to cram. So? How are you best going to preparefor the exam? In this article, I'll guide you through how to prepare quickly, including what to focus on for each section of the test and the best test-day techniques. Cramming for the PSAT: General Guidance There are a few over-arching principles that are crucial to the crammingprocess. Commit to Putting in the Time, but Don't Overstress the Test Time is of the essence,and you'll need tospend a lot of it preparing for the test.Don't give up on your homework, though- grades are hugely important in the bigger picture of college admissions, far moresothan the PSAT. The PSAT is not going to determine your fate. Its primary role is to help you understand where you stand as you start thinking about the SAT.No matter how good or bad your scores, colleges won't see them. The one thing your PSAT score does count for is theNational Merit Scholarship. If this matters to you, you'll probably need to put in more time to reachthe score cutoff for your state. Regardless, don't blow the PSAT's importanceout of proportion - if you do poorly, just make sure you start studying for the SAT earlier! Cramming for the PSAT is hard work. It will not, however, build muscles. Listen to Your Own Needs As you're preparing for the test, make sure to take care of yourself. Rest is beyond important.Practice good sleep hygiene and enact a decently early bedtime starting a good week before the test. Your bodystarts storing sleep not just the night before an event, but the night before that.Plus, if your sleepis usually limited (or simply not great), getting enough sleep can make you experience some extra fatigue, initially- so give your body time to adjust to getting rest. Temper healthy nerves by way of a reality check. As we said above, it's not the be-all, end-all of your life, your schooling, or even your high school career. Keep your confidence, and your calm. Limit stress, fatigue, and pessimism (in other words, the effects of overwork). Monitor your mindset: this is an opportunity to shine, not just a chance to get stomped on. How to Cram for the PSAT You may not havemuch time, but you do have some. Put those last few days or weeksto good use! Cooking, like the taking the PSAT, requires lots of preparation. #1: Take a Practice Test The first thing to do is take a full-length practice test. It's best to take it under test-day conditions if you can, but, if that's not possible, just make sure you get through the thing. If nothing else, this will serve as an opportunity to get thoroughly acquainted with the instructions and what they mean in practice. This will boost your confidence and decrease the time you waste on test day trying to figure out what you're expected to do. This is also a chance to acclimate to the types of questions on the test. Take note of the style and wording of the questions. Especially note that not all questions are technically questions- some include a command term and end in a period. (This is the difference between, "What is the solution?" and "Identify the solution.") See if you can find any patterns. Certain types of questions and formats of possible answers show up disproportionately. Perhaps most importantly, a practice test will show you whichareas need some extra attention. Ideally you should reviewevery section of the test as you prepare, but give documented weaknesses additional care. #2: Drill Official Questions This tip applies to all sections: drill real PSAT questions. There's nothing like practicing with official questions to show you where your potential difficulties lie. Both quality and quantity matter. You want to work as many problems as you can, but you also want to dissect what's going wrong when you make mistakes and work through the same (tricky) problems multiple times to get the hang of those routines. The more you go through the process, the more comfortable that process will become. #3:Read a Lot You don't have a lot of time, but spend your spare minutes immersed in literature. You're going to be doing a lot of reading on both the Reading Test and the Writing and Language Test, so getting comfortable understanding different types of texts is extermely important to excelling on the PSAT. However, not all reading is created equal. Reading for pleasure and entertainment is amazing. Right now, though, our focus is this test. Reading what's uncomfortable and unfamiliar builds new connections in your brain- not to mention that there's just more meat to dissect, anddissecting text is exactly what the test wants from you. The PSAT is going to present some pretty dense text, and you need to be at least somewhat used to looking at non-contemporary, formal, and/or academic literature.Read attentively and read critically, and get in as much as you can. Granted, this would work better if you were starting the process sooner, but even just acclimating to reading unfamiliar texts quickly will be helpful. If you dive right in now, it'll seem less stressfulby test day. This cactus didn't prepare before test day, and now see how overwhelmed he is? #4: Review Basic Grammar For the Writing and Language section, you absolutelymustknow the basic grammar rulescovered on the tests.You can't just follow your ear- there are many common errors that sound completely correct, and thesewill be on the test. Happily, there are relatively few concepts tested on this section, so you can cover the main ones very quickly. Even a few hours of review can make a big difference in your score. #5: Get Comfortable With Your Tools for Math Review the formulas that will be given to you on the test, as well as those you'll need to have memorized. As for the ones in your test booklet, they're no good to you if you barely recognize them; get familiar with them. As for the rest, you'll be on your own on test day when you find you need them. Practice rearranging equations; there's alot of algebra on this test, and mathematical manipulation is one of the primary skills that the test-makerslook at. Finally,ake sure you're comfortable with your calculator. Even if you've been using it in math class, try it out on some of the math problems that you're drilling (you are dirlling, right?). There are a few odd functions that'll come in handy, and you may or may not be familiar with them now. Also make sure your calculator is approved. Don't bring an abacus to the PSAT. PSAT Test-DayTips No matter how much studying you've done (or haven't done), there are a few solid principles that can make test day run much more smoothly. Warm Up the Morning Of Wake up, stretch, do your thing- and then do a bit of a warm-up. Review tricky practice problems that you've persevered in mastering, and try a fresh, new problem or two. Don't go beyond a simple warm-up, though: don't try to cram new material into your head. At best, it won't stick; at worst, it will muddle you up and stress you out. Feeling Panicky? Work It Out Self-talk is huge. How are you treating yourself? Kindly? Gently? Compassionately? Avoid being harsh or judgmental. Instead, affirm your assets: you've prepared, and you're ready. Put your game face on. Visualize the specifics of what's going to happen- and how you're going to handle it all like a champ. Let's try not to end up like this guy- he's not eveninside the test center yet. Answer Every Question There's no guessing penalty, so you can'tlose anything by bubbling in a choice. Do what you know how to do first. Next, eliminate answers where you can. Then, guess away! Guess on everything that's left. Leave nothing blank. To use this technique to your especial advantage, take a moment to read about how to guess strategically. Conclusion It's always best to start any study program with plenty of time before an exam. When that doesn't happen, though, or when it's just not possible, some types of cramming are smarter than other types of cramming. When it comes to the PSAT, taking a practice test and drilling extra practice questions can give enormous benefits. Beyond that, a lot of it is reading and reviewing basic rules. Also, remember: you're going to be working hard, so it's especially important to take intentional care of yourself. What's Next? Learn about the score range associated with the PSAT, so you know what general kinds of numbers you might expect to see when scores come out. Wondering exactly when scoreswill come out? It's a great idea to check out the dates to look for. If you're not sure what agood score might look like, though, take a moment to read about why that's a more complicated question than it seems. Get a sense of what an appropriate goal would be for you, while you're at it. Don't repeat the procrastinate-and-cram cycle for the SAT or ACT; start preparing earlier next time around. Take practice tests, and consider a prep program: PrepScholar has a great, customized program developed by experts, complete with a score-improvement guarantee. Want to improve your SAT score by 160 points or your ACT score by 4 points?We've written a guide for each test about the top 5 strategies you must be using to have a shot at improving your score.

What is Stereotyping

What is Stereotyping Free Online Research Papers A stereotype is a generalized perception of first impressions: behaviors presumed by a group of people judging with the eyes, criticizing ones outer appearance (or a population in general) to be associated with another specific group. Stereotypes, therefore, can instigate prejudice and false assumptions about entire groups of people, including the members of different ethnic groups, social classes, religious orders, the opposite sex, etc. A stereotype can be a conventional and oversimplified conception, opinion, or image, based on the assumption that there are attributes that members of the other group have in common. Stereotypes are sometimes formed by a previous illusory correlation, a false association between two variables that are loosely correlated if correlated at all. Though generally viewed as negative perceptions, stereotypes may be either positive or negative in tone. Sociologist Charles E. Hurst of the College of Wooster states that, â€Å"One reason for stereotypes is the lack of personal, concrete familiarity that individuals have with persons in other racial or ethnic groups. Lack of familiarity encourages the lumping together of unknown individuals†. Different disciplines give different accounts of how stereotypes develop: Psychologists focus on how experience with groups, patterns of communication about the groups, and intergroup conflict. Sociologists focus on the relations among groups and position of different groups in a social structure. Psychoanalytically-oriented humanists have argued (e.g., Sander Gilman) that stereotypes, by definition, the representations are not accurate, but a projection of one to another. Stereotypes are not accurate representations of groups, rather they arise as a means of explaining and justifying differences between groups, or system justification. Social status or group position determines stereotype content, not the actual personal characteristics of group members. Groups which enjoy fewer social and economic advantages will be stereotyped in a way which helps explain disparities, such as lower employment rates. Although disadvantaged group members may have greater difficulty finding a job due to in-group favoritism, racism, and related social forces, the disadvantaged group member is unjustifiably characterized as unmotivated (he could find a job if he looked hard enough), unintelligent (hes not smart enough to have that job), and lazy (he would rather take hand-outs than work). Stereotypes focus upon and thereby exaggerate differences between groups. Competition between groups minimizes similarities and magnifies differences. This makes it seem as if groups are very different when in fact they may be more alike than different. For example, among African Americans, identity as an American citizen is a more salient categorization than racial background; that is, African Americans are more American than African. Yet within American culture, Black and White Americans are often seen as completely different groups. For as long as there has been a human species, individuals have been different from one another. Persons have gravitated to groups of other persons like themselves. People create and develop categories of qualities by which to classify the groups; some were based on ancestry. Many of these groupings have become the key factors in determining which groups have political, social, and economic power in the world. Automatic stereotype activation can be totally involuntary, and is described as the activation of categorically associated nodes, according to Leopold and Brown from the Journal of Personality and Social Psychology. For individual people there can be both positive and negative effects of a stereotype which is seen to apply to them. The overall effects of stereotyping are seen by many to always be negative. Some people believe that stereotypes are generally based on actual differences. Others believe that they are always false generalizations (by definition). For some individual people the effects of this might be positive or negative a separate issue to whether they are positive or negative for society. Stereotypes can be self-fulfilling to at least some extent. Stereotypes can be deeply embedded in a culture. The term stereotype is more often used once those perceived truths are put into arguments. There are some complicating factors which arise when the accuracy of stereotypes is discussed. One of these is that a factor leading to stereotyping can be the existence of a group of people who do share a characteristic. For instance, there might be a reasonably significant number of men working in sales roles, and showing little integrity and honesty. This can lead to the creation of a stereotype of a salesman figure. In this limited sense it might be seen that the stereotype is based on a real group of people (i.e. salesmen who behave with little integrity). Stereotype is often used as a form of dramatic shorthand for stock character. Stereotypes change with time. The unwitting use of some stereotypes appears awkward to a present-day audience which refuses to tolerate a representation of individuals based on that stereotype. Many other stereotypes pass unnoticed, sometimes even by those being stereotyped. Bibliography Hurst, Charles E. Social Inequality: Forms, Causes, and Consequences. 6.

Calydonian Boar Hunt

Calydonian Boar Hunt What Is the Calydonian Boar Hunt The Calydonian Boar Hunt is a story from Greek mythology chronologically following the voyage the Argonaut heroes took to capture the Golden Fleece for Jason. A group of heroic hunters chased after a boar sent by the irate goddess Artemis to ravage the Calydonian countryside. This is the most famous of the Greek hunts in art and literature. Representations of the Calydonian Boar Hunt The earliest literary representation of the Calydonian boar hunt comes from Book IX (9.529-99) of the Iliad. This version doesnt mention Atalanta. The boar hunt is clearly shown in art work, architecture, and sarcophagi. Artistic depictions run from the 6th century B.C. through the Roman period. Principal Characters in the Calydonian Boar Hunt Meleager - Hunt organizer and killer of the boarOineus (Oeneus) - King of Calydon, in Aetolia, who failed to sacrifice to Artemis (hubris)Calydonian Boar - the fierce animal who ravaged the countryside as Artemis sent him to do.Artemis - virgin goddess of the hunt who sent the boar and may have trained Atalanta.Atalanta - Female, Amazon-type, a  devotee of Artemis, who draws first blood.Althaea (Althaia) - daughter of Thestius, wife of Oineus and mother of Meleager who causes her sons death when he kills her brothers.Uncles - Meleager kills at least one of his uncles and is then killed himself. Apollodorus 1.8 on Heroes of the Calydonian Boar Hunt Meleager, son of Oeneus, from CalydonDryas, son of Ares, from CalydonIdas and Lynceus, sons of Aphareus, from MesseneCastor and Pollux, sons of Zeus and Leda, from Lacedaemon Theseus, son of Aegeus, from AthensAdmetus, son of Pheres, from PheraeAncaeus and Cepheus, sons of Lycurgus, from ArcadiaJason, son of Aeson, from IolcusIphicles, son of Amphitryon, from Thebes [Sometimes the name Iphicles is given an uncle of Meleager]Pirithous, son of Ixion, from LarissaPeleus, son of Aeacus, from PhthiaTelamon, son of Aeacus, from SalamisEurytion, son of Actor, from PhthiaAtalanta, daughter of Schoeneus, from ArcadiaAmphiaraus, son of Oicles, from Argossons of Thestius. Basic Story of the Calydonian Boar Hunt King Oineus neglects to sacrifice annual first fruits to Artemis (only). To punish his hubris she sends a boar to ravage Calydon. Oineus son Meleager organizes a band of heroes to hunt the boar. Included in the band are his uncles and, in some versions, Atalanta. When the boar is killed, Meleager and his uncles fight over the trophy. Meleager wants it to go to Atalanta for drawing first blood. Meleager kills his uncle(s). Either a fight ensues between Meleagers fathers people and his mothers, or his mother knowingly and deliberately burns a firebrand that magically ends Meleagers life. Homer and Meleager In the ninth book of the Iliad, Phoenix tries to persuade Achilles to fight. In the process, he tells the story of Meleager in a version sans Atalanta. In the Odyssey, Odysseus is recognized by an odd scar caused by a boar tusk. In Judith M. Barringer ties the two hunts together. She says they are both rites of passage with maternal uncles serving as witnesses. Odysseus, of course, survives his hunt, but Meleager isnt so fortunate, although he survives the boar. Death of Meleager Although Atalanta draws first blood, Meleager kills the boar. The hide, head, and tusks should be his, but he is enamored of Atalanta and offers her the prize on the controversial claim of first blood. A hunt is a heroic event reserved for the aristocrats. It was hard enough to get them to participate in Atalantas company, let alone give her the principle honor, and so the uncles grow angry. Even if Meleager doesnt want the prize, it is his familys to have. His uncles will take it. Meleager, young leader of the group, has made up his mind. He slays an uncle or two. Back at the palace, Althaea hears of the death of her brother(s) at the hands of her son. In revenge, she takes out a brand the Moirae (fates) had told her would mark the death of Meleager when it was burned completely. She sticks the wood in the hearth fire until it is consumed. Her son Meleager dies simultaneously. Thats one version full of magic and a very non-maternal mother. There is another that is easier to stomach. Apollodorus on Version 2 of the Death of Meleager But some say that Meleager did not die in that way, but that when the sons of Thestius claimed the skin on the ground that Iphiclus had been the first to hit the boar, war broke out between the Curetes and the Calydonians; and when Meleager had sallied out134 and slain some of the sons of Thestius, Althaea cursed him, and he in a rage remained at home; however, when the enemy approached the walls, and the citizens supplicated him to come to the rescue, he yielded reluctantly to his wife and sallied forth, and having killed the rest of the sons of Thestius, he himself fell fighting.

Principles of Business - Research Paper Example The company also encourages its employees to volunteer in community outreach activities. The foundation supports Grace Foundation, World Vision and Asia Society in China, Taiwan and Hong Kong respectively. Hong Kong Council of Social Service awarded JP Morgan Chase foundation â€Å"The Caring Company†. Apart from external undertakings, CSR is also concerned with improving organizational management, mitigating overall risks facing the organization and stress proper use of company’s resources. Therefore, it is an activity meant to support company’s positioning to enable it take advantages of both foreseen and unforeseen opportunities. Connection between CSR program and its importance to bank According to Werther and Chandler (2010), CSR is an activity performed by banks and other companies to the community and environment to impact positively to the society and increase their overall competiveness. It integrates legal, ethical, economic and discretionary actions th at affects overall economic performance of the company. CSR seeks to provide the bank with sustainable competitive edge as it improves the reputation of the bank in the eyes of the governments and societies. Financial contracts and agreements executed by banks are characterized by uncertainty and asymmetrical information that makes good reputation and trust condition for conducting business. Therefore, CSR improves banks reputation and increases the level of trust. How does the CSR program apply to today’s trends and current issues in the global marketplace? Customers are increasingly getting versed with the need for investment in societies. Therefore, such customers are less likely to be customers of companies that exploit employees or that pollute the environment or those that are corrupt or carrying out illegal activities. Therefore, it is important for companies to maintain good relationship with the community in which it operates. Whom is the company responsible to? The company is responsible to the society in which it operates. Therefore, it must ensure that it operates business that improves lives of the people. Why a company implements a CSR program First, CSR protects shareholders and improve relationships with banking and investors. Shareholders understand that their investments gain better values not only through profit maximizing behavior but also operating in a responsible manner. CSR encourages companies to appoint board of directors who will deliver exemplary returns according to expectations of shareholders as well as protect company’s wealth and investments. With CSR programs, activities will contribute to bank’s strategic plan and shareholders will be assured of increased wealth emanating from steady dividends. CSR program demonstrates improved organizational management as well as improved processes in the bank. It also acts as channel of communication and reinforces relationships between shareholders and bankers as well as bankers and the community at large. Companies that have good reputation have undisputed advantage in convincing investors and other company stakeholders to support the company achieve its objective. Most investors prefer companies with strong CSR programs. Secondly, CSR improves stakeholder perceptions. Company’s stakeholders are many and varied. It is necessary to portray a good name for the company so that stakeholders of the company could be respected, trusted and liked. When stakeholder

Solving Eurozone Financial Crisis Essay Example | Topics and Well Written Essays - 250 words - 1

Solving Eurozone Financial Crisis - Essay Example For Buruma to suggest a political solution is a wild unrealistic dream since European region is synonymous with self-centered political and democratic interests. Indeed, a flashback on causes of World War 1 and World War 2 had the strong political correlation that has since then made states more cautious on interstate politics and democracy issues. Zakaria, on the other hand, suggests a workable financial solution to Greek’s financial nightmare. Bailouts and financial restructuring have not worked so far largely because they have not provided favorable economic growth for Greece. Greece and Italy crisis is not just a problem of respective countries but a financially cancerous disease for entire Europe. Europe can only resuscitate Greece’s economy by enabling Greece to attract capital and investments whilst keeping wage bill within manageable limits. The moment Greece starts recording positive economic growth, recovery will be guaranteed. This approach is highly likely t o succeed since it does not require dramatic political and democratic restructuring of entire Europe zone. In simple terms, it is better to show Greece â€Å"how to fish† instead of â€Å"lending them a fish† every time they are hungry.

Museum research paper Example | Topics and Well Written Essays - 750 words

Museum - Research Paper Example Most of the animals used in the painting all can cause harm and even lead to loss of human life. However, there is some twist when it comes to the bird. The whole idea of the painting is to symbolize a society where a man needs to be careful when ruling or running his life. The elephant depicts danger that is huge and can be detected from a distance. Such calamities strike severely if not dealt with before hand. The flamingo shows the beauty of the land. Such people may be good and appreciating in life and end up making it even sweeter. Despite the good aspect of peace with the bird, there lies an even bigger danger with the snake. The snake is used symbolically to point at issues, which creep in slowly by slowly and cause detrimental hazards. This may include addictions, drug abuse, failing to service a mortgage amongst others. The bitter peel is that such troubles are nearer than we thought and we are at times blind to them. The land life as depicted in painting appears to be safer compared to water life. The set of aquatic animals the artist uses are known to cause serious damage to human life. The hippo, crocodile, the shark and the polar bear keep man off these areas. The hippo is a silent ruthless creature; the crocodile on the other hand is a slow yet powerful animal that kills its prey using its powerful jaws. The shark sharps teeth and sensory system is able to detect blood miles away and faster to catch the prey. The polar bear has sharp claws and powerful arm that tear flesh very easily and fast. Happy human life can only be achieved by careful balance and keen consideration of every move made in life (Hall 17). The man is able to dominate at the center with careful balancing all his surroundings. Even though the snake is dangerous, man should device a way of maintaining close relationship and be alert of all its impending dangers (Hubbard 149). Where you can avoid trouble, keep them a

To what extend can it be argued that blogs encourage active citizens - Essay Example ontain reflections about daily life and produced by individuals with the primary audience being other bloggers that the individual links with on a regular basis. However, the blogs do not have any restriction on access and can therefore available to anyone. Even as a majority of blogs contain personal reflections, blogs that have had profound influence on society due to their wide readership are those that focus on matters of public interest. This essay focuses on the role played by blogs targeting public interests in order to assess the role such platforms play in encouraging active citizens (Herring, Scheidt, Wright and Bonus, 2005). The ability of blogs to attract public interest and therefore influence the way people interact and can be seen from the popularity gained by Instapundit.com written by Glenn Reynolds. The blogger a law lecturer at the University of Tennessee, had by March 2005 reached the hundred-millionth page hit plus a further 200,000 more hits on a daily basis. Given that Reynolds’ blog is dedicated to the commentary of current public affairs, it indicates the attraction of citizens to such blogs as a platform for them to contribute in what is going on around them. This further indicates the ability of blogs to generate popularity by attracting readership in most cases through their sharp, partisan commentary on current public affairs (Griffiths 2004). Further, a single blog has the ability to introduce readers into new debates and topic discussions through hyperlinks that lead readers to other topics that they might find interesting.

Importance of supervision in the workplace Research Paper

Importance of supervision in the workplace - Research Paper Example This small restaurant is among the favorite restaurants frequented by students from Fordham University. The menu comprises of snacks, entrees and drinks. This restaurant is unique as a buffet is located near the entrance whereby workers are line up with the main objective of providing quality service to the restaurant’s daily customers. A burrito bar is adjacent to the buffet. This burrito bar has all the items needed to make a burrito or a sandwich. The room adjacent the burrito bar towards the interior holds a machine packed with fountain beverages .This room also contains the soup and salad bar. The restaurant also contains a dining room with a table put near the register that acts as a resting place for the workers during breaks. The dining room holds three television sets with one connected near this table. It is also important to assert that the observations were performed in this area. Observation My observation for this report took four days to complete. The first thre e days of the observation were done with the absence of the head supervisor, Kimberly. Observation on the fourth day was done in the presence of Kimberly. This is attributed to the fact that Kimberly was on vacation on the first three days of the observation. Kimberly is an African American female aged twenty nine. She has a Bachelor of Science degree in Food Science, Nutrition, and Dietetics. The observation included taking notes on the different jobs as well as the special tasks that the employees were expected to carry out. The observation elucidated many jobs including cooks (four), entree servers (two), floor cleaners, pizza servers (one), salad bar runner (one), burrito makers and servers (two), cashier (one), dish washers (four), food runner (one), and student managers (eight). The work of the food runner involved transporting food from downstairs to upstairs. Gender roles As may be expected the jobs are distributed differently among the sexes. Serving and distributing food i s for the females. For instance, only females serve entree and burritos. Their job involves cutting food in distinct ways that are catching to the eyes due to their improved appearance. Mary and Jane, both from African origins were the experts in serving entree and burritos. Mary is twenty seven years old and a Kenyan while Jane is a twenty nine lady from Ghana. Both Mary and Jane have finished three years courses in catering and have both worked in this restaurant for one year. It is therefore hard to find a man serving and distributing food. On the other hand, males are involved in jobs necessitating lifting. For instance beverage worker are males are they are capable of lifting bags of syrup that are used in fountain beverage machines. Other roles associated with men include food runners since the task calls for heavy lifting at times. The floor jobs are also usually for men as they involve a lot of sweeping, moping, and lifting heavy garbage bags. One of the most respected clean er was George, a Mexican. George is forty years old, married, and a father of three. He is heralded as being one of the most behaved workers in the restaurant and has worked there for eight years. Therefore, gender roles seem to play an important aspect in deciding the duties of each and every employee. As asserted by Jeffrey and Streicher, â€Å"

Personal Statement on Philosophy of Education Research Paper

Personal Statement on Philosophy of Education - Research Paper Example From the understanding of the historical literature philosophy of education, it is worth noting that a learner or every child must be identified as a unique individual who needs to secure knowledge towards stimulating intellectual, emotional, social, and physical growth and maturity. Therefore, as an educator (Dhawan 79), it is my desire to help each student to meet his or her fullest potential in educational growth and maturity by providing for them with a safe environment that supports risk-taking and inviting sharing of ideas towards their knowledge growth and development. Notably, I believe that the three educational philosophy elements that I must apply to achieve these goals. These elements are usually conductive towards establishing proper learning and developing an environment in every learner’s education or learning process. These elements include the expectation of the teacher as the guide to any educational process; learners should be allowed to follow their natural curiosity and the same should to direct the learning process, and the last element is promoting respect among the learners. Therefore, it is understandable that it is my role as a teacher to guide and provide access to information to the students rather than being the primary source of the information to the students or learners. Hence, the learner should be in the forefront in search of knowledge such that their search of knowledge is quenched as they learn to provide an appropriate answer to their questions.... Hence, the learner should be in the forefront in search of knowledge such that their search of knowledge is quenched as they learn to provide an appropriate answer to their questions (Kilpatrick 38). Thus, the construction of knowledge needs the opportunity for discovering new practices and skills in authentic situations (Frankena 90). Therefore, as a teacher I understand that adequate access to hand on activities, as well as adequate space and time to students, is vital enable them to use the identified material to apply and reinforce acquired knowledge thereby allowing them with an individual opportunity to construct and discover knowledge. Additionally, other than providing learning materials and self-discoveries opportunities to the learners, it is vital to ensure that these materials are relevant and meaningful to the life and the interest of the learner. Achieving these targets can only be met through a constructive and thoughtful curriculum that revolves mainly around or foste rs intrinsic interests that motivate and stimulates the learner’s passion and interest (Kilpatrick 35). Therefore, curriculum is a vital tool that will help me to follow the right path towards helping the learner to achieve his or her interests and goals objectively and successfully (Elias 213). Notably, an effective curriculum can only be generated from learners’ ideas and set goals rather than creating the curriculum for educator’s self-imaginations (Frankena 132). In other words, as an educator, I will give students the opportunity to help in negating a curriculum and this will be achieved through viewing and analysing their interests. It is worth noting that when the students are taught by their own the curriculum, they will

A Range Of Problems In The Future Essay Example for Free

A Range Of Problems In The Future Essay ‘The world will have to grapple with a range of problems in the future’ The world will inevitably change as time continues to expose the past’s perception of the future to the now. As the earth ages, generations to come adapt to the new world they perceive to be as It is near impossible for every parent to educate their young on everything they have ever learned; thus attitudes and morals are continually fluctuating. It is undeniable that it has already affected society it is evident throughout today’s problems that were never pondered upon by older generations such as the rapid advances in technology. The future can only change, and will encounter many dilemmas along the way. Earth already has an overwhelming number of human inhabitants, and the world’s population continues to increase. Many people do not want to acknowledge the problem, but ignorance will not change the inevitable consequences of overpopulation. No animal species can exist without adequate food, water, shelter and other essential resources and humans are not exempt from this rule. When the human population exceeds the resources needed to sustain it, the same thing that happens to any overpopulated species; nature will reduce the population through famine, disease, interspecies fighting or a combination of either one. That reality has already affecting people in some Third World countries. Because of cultural, political and religious attitudes, almost no world leader is willing to acknowledge the problem, much less take the necessary steps to resolve it. The underlying cause of almost every environmental problem in the world today is human overpopulation. Air pollution, water shortages, habitat loss, extinctions, and invasive species all are caused or intensified from having too many people in the world. Humans are unique among all animal species in having the ability to solve even a monumental problem like overpopulation. This awareness is existent in George Orwell’s ‘1984’, the effects of extreme totalitarian society have stripped society’s resources and forced them to live in a dystopian environment full of pollution and overpopulation. Such a situation of local overpopulation has existed since the dawn of humanity and is slowly becoming a global existential problem. Technology today has transformed the world and changed how people live in their day to day lives. As advances in technology are generally perceived to be an advantage, it can enable the most malevolent evil. The realm of communications has likewise seen immense change. People are provided with new ways to communicate with each other, such as email and instant messaging which can pose as a breach of privacy if used for the wrong intentions. Documents placed on the internet are sources of information for the rest of the world, and will forever leave a digital footprint. Global positioning satellites allow us to track our exact location and find our way to various destinations; such accessible conveniences can alter the future in foretelling ways. George Orwell’s ‘1984, illustrates a dystopian society ruled by a totalitarian government. This extreme realization portrays a government with absolute power, in which controls every aspect of human life using a number of dehumanising techniques. Orwell’s dark vision poses as a foreshadowing notice, which thoroughly explores the consequences of advanced technology and its misuse. As Oceania’s mechanical citizens are constantly monitored using microphones and surveillance, expunges their right to privacy and to make choices. It is clear that the innovations of technology could escalate out of control, leaving society with no defence against it. Thus, it will ultimately destroy humanity in the pursuit of absolute power. The discovery of DNA has the possibility to lead to major social and scientific issues in society. With new advances in technology, there are increases in the consequences that the new technology will allow. It is evident in Andrew Niccol’s film ‘Gattaca’ that the more powerful genetic engineering becomes the more helpful and harmful it develops. The film depicts a society ruled by ‘genoism’, where your genetics decide your social class in the world with a stressed need for perfectionism. This depressing image where there is no determinism for fate or influence for ethical standards eliminates the right for freedom of choice, that people freely and obliviously exhaust today. The consequences of selective breeding solutions are frequently addressed in past and modern literature. In ‘Jurassic Park’, a scientist exhumes and modifies dinosaur DNA to then create an island inhabited by dinosaurs. Consequently, the impact of unnaturally producing a breed that has been extinct for a long period of time threatened the rest of  the human race’s existence. It is clear that such meticulous science created in the wrong hands has the potential to impact the world permanently. Similarly, a frightening futuristic concept that threatens to dominate society is totalitarianism. The objective of totalitarian government is to limit and regulate every aspect of public and private life. George Orwell’s novel, ‘1984’, exemplifies a society lacking in freedom and expression. His fictional society in the year 1984 stands as a metaphor for a totalitarian society. Communication, personal beliefs, and national loyalty are controlled by the inner party which governs the people of Oceania in order to keep society from rebelling. The concept of also controlling the personal beliefs of the citizens promotes totalitarianism by limiting the form of any emotional or individual expression. The citizens of Oceania were forced to work long days which limited self-expression because they were too exhausted to do anything else. Oceania, where protagonist Winston Smith lives, is ruled by the INGSOC. â€Å"BIG BROTHER IS WATCHING YOU†, the main party slogan of Oceania which makes clear that every action you make is all seen by Big Brother, the big leader. The Inner Party, controlled by Big Brother, dictates several aspects of the people’s life. As a society, Oceania are completely brain washed by the continuous propaganda which is based on false news, a new language which reduces the capacity of using words in a double sensed way named Newspeak and indoctrination, this newborn dialect empowers and respects INGSOC. The overall concept is designed to control personal beliefs of the citizens by limiting their form of expression. Essentially, controlling the communication aligns with the Totalitarian aspects of governing. George Orwell envisioned the lack of communication could possibly result to total dominance and control of the people. As civilization moves toward the point where human life will be irreversibly transformed, it will also have to overcome the potential problems that are carried along with any advancement in technology and government. All of these possibilities portray a pessimistic view of the future which has the potential to accrue into tremendous issues of whom the world will have to grapple.

The Importance Of Heat Integration In Distillation Columns Engineering Essay

The Importance Of Heat Integration In Distillation Columns Engineering Essay The combination of high crude oil prices due to increasing energy demand and concern about pollution has led researchers to exploring the possibilities of more energy efficient and environmentally friendly process technologies. The importance of distillation as a separation technique has made making it more energy efficient a high priority. Consequently, many heat integrated design schemes have been produced through the decades that it has been investigated and many of these techniques are outlined in this report along with some current commercial schemes. However, this technology has not been fully commercialised and this is mainly due to the high initial investment costs and the complexities of the equipment design, control schemes and operation. There is also a lack of real experimental data that is needed in order to verify the many theoretical predictions that claim that large energy saving are possible. Several areas have been identified as in need of further research in the fu ture to hopefully allow this technology to become an industrial standard and not just a theory. Introduction 1.1 The Importance of Heat Integration in Distillation Columns The combined threat of increasing energy demands and costs, global warming and the increased dependence upon oil imported from politically unstable parts of the world have resulted in an interest in enhancing the thermodynamic efficiency of current industrial processes. Increasing energy efficiency in chemical processes not only provides economic benefits but also it leads to reduce the emissions resulting from the process operation. Distillation is perhaps the most important and widely used separation technique in the world today as it is used for about 95% of all fluid separation in the chemical industry. In the US, about 10% of the industrial energy consumption accounts for distillation while it accounts for an estimated 3% of the world energy consumption. More than 70% of the operation costs are caused by the energy expenses (Nakaiwa et al. 2003.) It is a fact that the energy consumption in distillation and CO2  gases produced in the atmosphere are strongly related as the highe r the energy demands are the larger the CO2  emissions to the atmosphere are. This is due to the energy being mostly generated through the combustion of fossil fuel. Despite its apparent importance the overall thermodynamic efficiency of a conventional distillation is only around 5-20% (Jana, 2009). Clearly, improving on this value is imperative and a top priority objective. In order to achieve this, the concept of heat integration was introduced almost 70  years ago (Jana, 2009.) The basic idea of heat integration is that the hot process streams are heat exchanged with cold process streams which results in a more economic use of resources. Consequently a whole range of heat integrated distillation schemes have been proposed. In a conventional distillation column (Figure  1) with a feed, a top product and a bottom product, heat is added at the bottom of the stripping section. In distillation, heat is used as the separating agent. The heat is conventionally supplied at the bottom reboiler in order to evaporate a liquid mixture but is lost when liquefying the overhead vapour at the reflux condenser. The temperature of this heat corresponds to the highest temperature point in the distillation column. The temperature of the heat rejected at the top of the rectifying section corresponds to the lowest temperature point in the distillation column. Thus, distillation involves the loss of heat from a higher temperature level to a lower temperature level in order to perform the work of separation. The efficiency of distillation is reduced if the heat rejected in the rectifying section of the distillation column is not reutilized (Smith, 2005.) This is the principle from which heat integration of distillation is m ainly based. Full-size image (28 K) Figure A schematic representation of a conventional distillation column (Kiran, 2012) 1.2 Benefits and Drawbacks of Heat Integration The possible benefits of heat integration tend to be potential energy savings due to greater efficiency and also less waste. Unfortunately due to a number of issues the technology has yet to be commercialised. Installation of any type of heat integration will entail a higher capital investment than that of any standard distillation column due to the increased complexity of the design. Also, the amount by which the efficiency is improved by is not always substantial in certain cases and therefore it must be considered whether the perceived benefits from the greater efficiency outweigh those of the added costs. The increased complexity can also increase the difficulty of designing, operating and controlling the system. There has also been a lack of experimental data for large scale examples to verify theoretical predictions. A successful heat integrated column design would show positive energy savings at reasonable economic figures that can be effectively operated and controlled. 2. Energy-efficient distillation techniques This section discusses some of the many heat integrated techniques that have so far been proposed with the purpose of improving the energy efficiency of separation processes. 2.1 Pseudo-Petlyuk column The thermally coupled distillation scheme was first patented by Brugma in 1937. The process is used for separating a ternary feed and consists of a conventional prefractionator and side stream tower. Both of these parts are equipped with a reboiler and a condenser. The unit is divided vertically by a wall through a set of trays in order to keep the feed stream and side product separated. It was Wolff and Skogestad (1995)who referred to this set up as a pseudo-petluk column. However, their research led to some concerns about serious issues during operation for high purity separations which would limit the effective use of this system in many cases (Wolff, 1995.) 2.2 The Divided-Wall Column The elimination of the prefractionator unit from the pseudo-Petlyk column leads to a configuration known as the divided-wall column (DWC) (Robin Smith et al, 1992.) It is displayed in figure 2. It is achieved by introducing a vertical partition into a distillation column to arrange a prefractionator and a main column inside a single shell. The advantage of this partitioned column is that a ternary mixture can be distilled into pure product streams with only one distillation structure, one condenser and one reboiler. Naturally the cost of the separation is reduced along with the number of equipment units which leads to a reduced initial investment cost. Subsequently, further research has been undertaken with for example Agrawal (2001) discussing for multicomponent mixture separation the various types of partitioned columns and their advantages and disadvantages. However, as a result of the lack of experience in design and control, the dividing wall columns were yet to be extensively used in industry. This is changing though and there has been a rapid growth in the number of units in use. In 2004 there were 40 units used worldwide (Adrian et al, 2004) Full-size image (11 K) Figure A schematic representation of a Petlyuk distillation column (also known as divided-wall column) (Jana, 2009). 2.3. Petlyuk column Petlyuk et al (1965) presented a detailed theoretical study on a divided-wall column called the Petlyuk column. This reduced Petlyuk structure involves low initial investment and consumes less energy which reduces the operating costs. However, upon comparison with a conventional distillation unit the Petlyuk column has many more degrees of freedom in both design and operation which can cause difficulty when designing the column and creating a control system. As displayed in figure 3, the two-column Petlyk configuration will commonly consist of a prefractionator connected to a distillation shell equipped with only one condenser and reboiler (Jana, 2009.). The thermal coupling in a Petyluk scheme has lead to large energy savings. Unfortunately, little progress has been made with regard to improving operation and control of the structure which hinders its usability. .

(Jana,2009) 2.4 Multi-Effect Column The basic idea of this method for separating multicomponent mixtures is to use the overhead vapour of the one column as the heat source in the reboiler for the next column. The columns may be heat integrated in the direction of the mass flow which is forward integration or back integration can be used with is in the opposite direction. A sample column that represents a multi-effect column with a prefractionator for a ternary mixture separation is displayed in figure 4. Full-size image (19 K) Figure A schematic representation of a multi-effect system for ternary (A-C) feed mixture (Jana, 2009) This integrated arrangement has been proved to provide considerable energy savings (Cheng et al, 1985.) However, the issue preventing commercialisation of the process is the operation difficulties owed to the nonlinear, multivariable and interactive nature of the process (Han et al, 1996.) More research must be undertaken to try and find appropriate solutions before there can be a more extensive use for this system and to make use of the energy saving potential. 2.5 Heat Pump-assisted Distillation Column The heat pump is mainly used as a way for increasing the thermal economy of a single distillation column. The heat pump-assisted distillation column or vapour recompression column (VRC) was implemented as an energy-efficient process for the chemical industries after an oil crisis in 1973 (Jana, 2009.) In the system the overhead vapour is pressurised by a compressor to the point where it can be condensed at an increased temperature which will supply the heat required in the reboiler. A schematic representation of this can be seen in figure 5. Full-size image (14 K) Figure A schematic representation of a heat pump-assisted distillation column (Jana, 2009) There are potentially large energy savings to be made, mainly for fractionating close boiling mixtures. This is due to the small temperature difference between the top and bottom of the column which will result in small compression ratios and consequently small compressor duties being required (De Rijke, 2007.) For a conventional distillation column attempting to fractionate the same close boiling mixture there will be a higher reflux ratio and thus larger reboiler duties would be required. The drawback for this technique is the high capital costs. Reducing the cost of running the heat pump-assisted distillation column would certainly increase its cost effectiveness and make it more viable as an option. 2.6 Heat integrated distillation column Using heat pump technology it is possible for separate rectifying columns and stripping columns to be heat integrated internally. This structure is a heat integrated distillation column (HIDiC.) Originally only part of the stripping and rectifying sections were integrated under the name of the SRV scheme but later column design has incorporated heat integration between the whole rectifying and stripping sections (Jana, 2009.) Figure 6 displays a typical partial energy integrated distillation scheme. Full-size image (26 K) Figure A schematic representation of a partial HIDiC scheme (Jana, 2009)) In this configuration the stripping column operates at pressure lower than the rectifying column. A compressor and throttling valve are installed in order to adjust the pressures. The pressure differential means there will be a corresponding difference in operating temperature which allows energy to be transferred between the two columns through heat exchangers. Reflux flow for the rectifying section and vapour flow for the stripping section is generated from the heat exchanged between the rectifying hot vapour and the stripping cold liquids. This allows the reboiler heat load to be substantially reduced. Less energy is consumed the more heat that is exchanged and through appropriate process design it can be possible for reflux and/or reboil free operations to be performed. It has been shown that the HIDiC, compared to the VRC, can lead to energy savings of about 50% (Sun et al, 2003.) However, the structure has a very complex design and requires large capital investment (Jana, 2009.) Meanwhile it has also been found find that there are many binary feed separations where HIDiC is actually less energy efficient than simple heat pump schemes using only one or two heat transfer locations. Furthermore, it was shown that the energy efficiency of HIDiC cannot be solely decided based on the feed composition or product purities as many calculations are based. A better performance indicator is the temperature profile along the height of the rectifying section relative to the corresponding temperature profile in the stripping section (Herron ,2011) Research is ongoing, focussing on the dynamics and the thermodynamic efficiency aspects while extensive research was undertaken by Suphanit (2011) focussing on optimal heat distribution depending on the column arrangement and number of heat exchangers. Suphanit also produced a couple of potential schemes display in figure 7. Full-size image (41 K) Figure Fig. 2. Internally heat-integrated distillation column (HIDiC) (a) and HIDiC constructed in a concentric column (b) (Suphanit, 2011) The development of HIDiC has now reached the pilot plant stage in some countries such as Japan and the Netherlands.  Despite this, further research, both in terms of design and hardware development issues, is still needed before this application can be fully established and accepted in commercial use while further detailed study on the economic evaluation of this column structure is needed in order to ensure its advantage over more conventional schemes (Suphanit, 2011.) 2.7 Heat Integrated Batch Distillation Column Batch distillation is generally known to be a less energy efficient option than its continuous counterpart. However, the batch distillation is extensively used in pharmaceutical, fine and specialty chemicals industry due to its greater flexibility where the demand and lifetime of the products can be uncertain and may vary significantly with time. Jana (2009) proposed a novel heat integrated batch distillation column (HIBDC.) The proposal was based on a binary batch distillation example that separates an equimolar ethanol/water mixture. In comparison with the conventional batch process, the HIBDC also includes a compressor. The produced vapour in this concentric reboiler is firstly compressed and is then introduced at the bottom of the rectifier. This results in a pressure difference between the rectifier and reboiler. Consequently, energy is exchanged from the rectifier to the reboiler through the internal wall and brings the downward liquid flow for the former and upward vapour flow for the latter. This reduces the reboiler and condenser heat loads. However, an additional compressor duty is involved in the thermally coupled column. Full-size image (28 K) Figure Schematic of a heat integrated batch distillation column (HIBDC) [D = distillate rate (kmol/h), L1 = flow rate of liquid leaving 1st tray (kmol/h), nt = top tray, Qc = condenser duty (kW), Qn = rate of internal heat transfer from nth tray (kW),R = ref reflux rate (kmol/h),  VB  =  vapor boil-up rate (kmol/h)] (Jana, 2009) From the investigation it was observed that the HIBDC system appears overwhelmingly superior to its conventional stand alone column providing a significant savings in energy as well as cost. The potential energy integration leads to achieving about 56.10% energy savings and 40.53% savings in total annual cost. However, a single example comparing different configurations does not indicate that the proposed method would perform equally successfully for all mixtures. Therefore it was proposed that further investigation would take place in the future to come to a full conclusion as to the future promise of this technique. Takamatsu et al. (1998) also performed a comparative study between the heat integrated batch distillation and the conventional batch distillation that proved the superiority of the heat integrated scheme over its conventional counterpart in terms of energy efficiency. However, no more development has been found with regard to energy-efficient batch distillation. 2. 8 Intensified Heat Integrated Ternary Distillation Column Kiran et al. (2012) extensively investigated a novel intensified heat integrated ternary distillation column (int-HITDiC.) Their objective was to show that the int-HITDiC was superior in terms of energy consumption and economics than its general form, namely the HITDiC and the conventional standalone column. It was also investigated that the traditional HITDiC scheme shows a reasonable energy household and better economic figures than the conventional standalone column. The int-HITDiC is a hybrid scheme which gets the advantage of both the HIDiC and VRC strategies. It was found that this kind of heat integration could help to improve the process design not only in terms of thermodynamic efficiency but also in terms of capital investment. The intensified scheme can be classified into two different structure based on the number of compressors: the single compressor int-HITDiC and the double compressor int-HITDiC. From experimentation it was found that the double compressor system provided the best performance in terms of cost and energy consumption where it produced a maximum energy saving of 59.15%. Another attraction of the proposed double compressor int-HITDiC was its least payback time of excess capital which was 3.44 years. The performance of this proposed thermal integration techniques was measured using a ternary distillation system. A more general conclusion regarding energy and economic viewpoints could be found by extending its application to other example processes and checking for a consistent performance. An issue that should be mentioned regarding intensification is that although economic benefit is usually achieved the operability of the column tends to be reduced. Also, if the HIDiC is sensitive to disturbances then potentially the economic, safety and environmental performance may be unfavourably affected (Kiran et al, 2012.) 2.9 Internally Heat-Integrated Reactive Distillation Processes Internally heat-integrated distillation and reactive distillation are two promising technologies that can potentially result in considerable economical benefits. Jiao et al. (2012) conducted a study regarding internally heat-integrated reactive distillation; a technology which combines internally heat-integrated distillation and reactive distillation and is employed in order to further enhance the advantages of both technologies. The study tested three ideal quaternary systems, that reactive distillation processes with internal heat integration have been designed to use, to find which had the best potential for decreasing the total annual cost. These systems are types IP  and IIP  with stoichiometric design and also type IR which has excess design. In the case of type IP which has the reaction zone located in the centre of the reactive distillation column (RDC,) M-HIRDC will provide the highest economical benefit for the endothermic and exothermic reactions, chemical equilibrium constants and various relative volatilities. Here the reaction rate in the reactive trays in the high pressure section increases while in the reactive trays located in the pressure section the reaction rate will decrease. It is desirable to use HIRDC. The reaction zone is located at the bottom of the RDC when using type IIP  . Here the process with M-HIRDC will have better economical design than that of a conventional reaction distillation process in the case of both exothermic and endothermic reactions. The M-HIRDCs reactive trays are mostly positioned in the low-pressure section. Due to low pressure and temperature values the reaction rate is also smaller. It can be concluded that there are only minimal benefits to using HIRDC. The final system, type IR, has its reaction zone placed at the top of the RDC. This process shows the smallest total annual cost for the endothermic and exothermic reactions. The reactive trays are situated in the HP section and due to the increased temperature and pressure values the reaction rate is also increased. Thus, HIRDC is again a desirable operation. In conclusion, when the reaction zone is situated at the top of the column the lowest total annual cost will be found for the RDC. 2.10 Externally Heat-Integrated Double Distillation Column Liu et al. (2011) investigated the potential of externally heat-integrated double distillation columns (EHIDDiC.) In terms of the separation of an ideal binary mixture of hypothetical components A and B, the synthesis and design of the EHIDDiC were studied with the assumption of a constant pressure elevation between the low-pressure (LP) to the high-pressure (HP) distillation columns that are involved. It was found employing between one and three external heat exchangers results in a reasonable design option for the EHIDDiC. When a number of external heat exchangers greater than three were employed the process configuration has to be carefully determined as the increase in number of stages externally heat-integrated may not actually be beneficial to the system performance. This is due to the strong mass and heat couple between the LP and HP distillation columns that are involved and reflects the unique feature of the EHIDDiC. To reduce capital investment, the total external heat exchange areas should be installed through as small a number of heat exchangers as possible. The extreme situation would be the employment of a single external heat exchanger which would need knowledge in arranging the total heat heat transfer areas between the HP and LP distillation columns involved. These findings are of great significance both to process synthesis and design. A novel decentralised control scheme was also proposed for use for EHIDDiC operation. (Liu et al, 2011.) Huang et al. (2011) investigated three different configurations for externally heat-integrated double distillation columns performances for separating a binary mixture of ethylene and ethane. The configurations were a symmetrical EHIDDiC (S-EHIDDiC), an asymmetrical EHIDDiC (A-EHIDDiC), and a simplified asymmetrical EHIDDiC (SA-EHIDDiC), which were compared with respect to aspects related to process design and controllability. It was found that the A-EHIDDiC and SA-EHIDDiC were both superior to the S-EHIDDiC in terms of thermodynamic efficiency as well as in terms of process dynamics and controllability. Upon comparing the A -EHIDDiC and SA-EHIDDiC, the latter showed similar behaviour with the former in terms of process design and controllability. These results demonstrated that the asymmetrical configuration should generally be favoured over the symmetrical one for the development of the EHIDDiC (Huang et al, 2011.) 2.11 The structured heat integrated distillation column Krikken et als (2012) recent investigation into a structured heat integrated distillation column showed that a plate-packing configuration using structured packing gave a superior performance in comparison with the HIDIC based on the plate-fin heat exchanger. Further experimentation showed that the mass transfer and heat transfer efficiency increased significantly with increasing throughput. However, this was accompanied by an increasing pressure drop per stage. By simulating an industrial scale plate-packing unit it was found that an even better performance is possible through increasing the volumetric thermal load by further optimisation of the internals. The principle of a S-HIDiC is shown in figure 9. Here the rectifier and the stripper are alternatively stacked in a sandwich of layers which creates a high surface area for the heat and mass transfer while maintaining a high voidage. Full-size image (36 K) Figure Flow scheme of an S-HIDiC.(Krikken et al, 2012) Internals are used inside the layers to optimize the HIDIC performance. In the plate-packing HIDiC, which was developed and tested in this study, both heat and mass transfer are in balance at an acceptable pressure drop. This result of this is a column design providing substantial cost and energy savings. It could be possible to optimise the column configuration even further by decreasing the number of heat integrated stages and by increasing the volumetric thermal load but research is ongoing with regard to this. It is also important to note that the results obtained were purely based on one experience with conventional packed columns so further optimisation of the performance through adjustment of the internals is required. It was also noted that in order to achieve this development of design models would be useful (Krikken et al, 2012.) 2.12 Other Noteworthy Techniques Other techniques worth mentioning but are not explored in detail here are the inter-coupled column, concentric HIDiC, the fractionating heat-exchanger (all outlined by Jana, 2009,) control systems for heat integrated distillation systems with a multicomponent stream (Amidpour et al. 2012) and membrane distillation system using heat exchanger networks (Lu et al. 2012.) 3 Industrial Applications 3.1 Using i-HIDiC to Separate a Close-boiling Mixture It has already been proven that HIDiC can be superior in terms of energy savings when compared to other thermally coupled and conventional distillation columns. In an attempt to broaden the application of the ideal integration concept the economical and operational feasibility of the i-HIDiC scheme has been explored for the use in separating components of a close-boiling multicomponent mixture. It was found to be possible to employ two ideal HIDiCs to separate a hypothetical close boiling ternary mixture and two options of a direct and indirect sequence have been considered just as with its conventional equivalent. It has been previously found that it possible to achieve 30% to 50% energy savings for the separation of two close-boiling mixtures using a HIDiC (Iwakabe et al, 2006.) However it was then found that the ideal HIDiC system is even more thermodynamically efficient than a conventional distillation system (Huang et al, 2007.) Huang et al. (2007) found a process that was conducted with minimization of the total annual cost in mind. They analysed the closed-loop controllability for the ternary mixture separation using the i-HIDiC and the intensified i-HIDiC. Upon comparison it was shown that the intensified i-HIDiC showed worse closed loop control performance with large overshoots and a longer settling out time due to the positive feedback mechanism that is involved within the intensified structure. 3.2 Heat-integrated Extractive Distillation It is not possible to separate a binary mixture which has a very low value of relative volatility as the two components will evaporate at almost the same temperature and at a similar rate. For such cases extractive distillation can be utilised where a third components called solvent (which is a high boiling and relatively non-volatile component) is added in order to alter the relative volatility of the original feed components. It has previously been investigated as to the effectiveness and operation feasibility of several energy-integrated extractive distillation technologies including the divided-wall column, Petlyuk column and heat-integrated extractive distillation scheme (Abushwireb et al, 2007.) The work included a comparison between energy-integrated extractive distillation columns and conventional extractive distillation technique based on the recovery of aromatics from pyrolysis gasoline using a solvent called  N-methylpyrolidone. The optimum design was found through using a minimal total annual cost as the objective function. The conclusion of the study was that the designed extractive distillation schemes should meet all expectations in terms of energy consumption and purity of cuts. It was shown that the heat-integrated extractive distillation configuration is the preferred option ahead of the Petlyuk column, divided-wall column and conventional column. 3.3 Separating Close-boiling Mixtures using Heat Integrated Pressure-swing Distillation Three commonly used techniques for fractionating a binary close-boiling mixture are azeotropic distillation, extractive distillation and pressure swing distillation (PSD.) The first two techniques require a third component called a solvent that enhances the relative volatility of the components that are to be separated. This can lead to certain drawbacks such as the solvent never being completely removed thus adding impurity to the products, the cost of solvent recovery, the loss of solvent and potential environmental concerns (Treybal, 1980.) These potential issues with using a solvent have allowed the PSD approach to emerge as an attractive alternative option. An important prerequisite for the use of a PSD column is that the azeotrope separate has to be pressure sensitive. Here you have a low pressure (LP) distillation column and high pressure (HP) distillation column that are combined to avoid the azeotropic point. The inclusion of the HP and LP columns in the PSD configuration allows for the possibility of heat integration to be explored. Two appropriate types of energy integration for PSD processes were shown by K. Huang et al. (2008.) The first is the condenser/reboiler type heat integration where the condenser of the HP distillation column is integrated with the reboiler of the LP distillation process. The other option is the stripping/rectifying section type heat integration where the stripping section of the LP distillation unit is coupled with the HP distillation units rectifying section. It was found that for se parating close-boiling mixtures the best option is the latter while for other types of mixtures the reverse is actually true. However it was clear that both types of heat integrated PSD column have potential for large energy savings when separating close-boiling mixtures. Yu et al. (2012) also developed a new method for separating methyal/methanol using PSD. There it was found that the fully heat-integrated pressure swing distillation process had lower costs due its energy saving capabilities. 3.4 Heat integrated Cryogenic Distillation Cryogenic distillation columns will generally operate at extremely low temperatures. An example of this the process of separating air into its basic components where the process will run at about 100K (Mandler, JA.et al. 1989.) This temperature is low enough that oxygen and nitrogen will be in their liquid state and can consequently be separated in the column. The cryogenic separation unit has a highly costly installation arranged with the condenser if the overhead vapour is meant to covert to liquid phase as the overhead vapour is enriched with more volatile component which has a very low boiling point. The heat integration principle can be used by coupling the reboiler and condenser in the cryogenic distillation unit in order to reduce this high energy cost. The energy that is expelled in the condenser can then be utilised in the reboiler. A heat integrated cryogenic distillation column (HICDiC) that is constructed with two smaller c
