Oil Discovery and its effect on democratic growth in Ghana Essay

Oil Discovery and its effect on democratic growth in Ghana - Essay Example Over the last decade, oil explorations in the Atlantic Ocean off to the coast of Western and Southern Africa have ushered the region of Sub-Saharan Africa into an oil boom. There was a rapid incursion of multinational oil companies from around the world seeking to exploit these untouched oil reserves (Jerome 9). This oil boom has given Sub-Saharan countries such as Nigeria, Angola and Sudan great opportunity to turn their situations upside down and steer their country towards a better future. However, in the midst of this great opportunity rest numerous pathologies such as high level of corruption, high risks of civil war, low prevalence of democracy, high poverty rates and poor economic growth (Jerome 9). Thus, the ensuing years of the oil boom was marked by a drastic realization for these countries. When Ghana gained its independence in 1957 from the British, it had one of the strongest economies in Africa. However, years after it gained its independence, numerous domestic problems have caused the economy to drop and further decline till the year 1980. For more than 15 years, Ghana was able to slowly recover through economic reforms and Ghana is now considered as one of the Africa’s brightest prospects. However, what made Ghana attain such status quo is the recent oil discovery in offshore Tan/West Cape three Points Basin in the Western Region of Ghana. Oil companies who led the explorations were Kosmos Energy of US and Tullow Oil of UK under the supervision of Ghana National Petroleum Corporation (GNPC). In an instant, Ghana joined the ranks of its fellow African countries who are also producing oil and it is also expected that for the next two decades, billions of pounds and dollars are expected to pour in Ghana (Lerrick 7). Unfortunately, the excitement did not last long for the people. Once the jubilation was over, people begin to wonder whether it is really oil that their economy needs in order to achieve its goal.

Peacekeeping and Collective Security Essay Example | Topics and Well Written Essays - 2500 words

Peacekeeping and Collective Security - Essay Example If the UN is to maintain its credibility, he says, it has to conserve its resources--unless its members are prepared to approach peacekeeping in a more serious and generous spirit. On May 13th Mr Boutros Ghali told the Security Council that it was impractical to send UN peacekeepers to Bosnia while the war there was still pursued with such ferocity. If the council members wanted to intervene, they should not try to do so on the cheap; they would have to consider sending in tens of thousands of troops equipped with offensive capability. Even if they opted, at this stage, only for armed escorts to protect the relief convoys, they would have to think along similarly expansive lines; a convoy led by the UN had been brutally ambushed by Muslim militiamen. But the council, ignoring his warning, voted two days later for the provision of armed escorts without going into their military needs. The new secretary-general, who for many years was the eminence grise of Egyptian foreign policy, is not a table-thumper, a politician or even a good speaker. But he is beginning to show a sure touch and may be less worried than his predecessor about making enemies. One sign of this is his readiness to accuse the council of telling him to find people to do difficult and dangerous things without giving them the wherewithal to do them. He believes that when regional groups are strong, as the European Community supposedly is, they should work more consistently to bring about a peace. The UN peacekeeping operation is kept permanently and humiliatingly on the verge of bankruptcy. If the Security Council insists on sending a force into Bosnia without adequate political and military backing, the result on the ground could be a cruel farce. The background to Mr Boutros Ghali's caution is that the newly assertive ambassadors at the Security Council, unlocked from American-Soviet rivalry, are trying to do something exciting, but they are doing it by stealth rather than accepting that there may have to be changes in approach. The argument for stealth is that pragmatism works; attempts to bring the changes into daylight could open a box of troubles. One of the troubles is the membership of the council itself: the five permanent members are the victors of the Second World War. Japan, murmuring from the outside, wants to join the permanent five by the time the UN has its 50th anniversary in 1995. More important, the new peacekeeping operations exploding around the council's head are no longer of the traditional kind and do not necessarily call for traditional answers, let alone traditional fund-raising. That the UN charter makes no mention of peacekeeping'' is handy since it lets members be inventive in stretching the international peace and security'' criterion. Iraq's invasion of Kuwait was exceptional in being the type of conflict the charter writers had in mind. Most of the conflicts with which the UN is now involved are civil or ethnic--domestic matters into which the Security Coun

The Office of Digital Communication manages the main Facebook, Twitter, Instagram, Foursquare, YouTube and Vimeo accounts. Furthermore, social media depend on mobile and web-based technologies to create highly interactive platforms through which individuals and communities share, co-create, discuss, and modify user-generated content. They introduce substantial and pervasive changes to communication between organizations, communities, and individuals.These changes are the focus of the emerging field of  technoself  studies. Social media are different from traditional or industrial media in many ways, including quality, reach, frequency, usability, immediacy, and permanence Diagram depicting the many different types of social media There are many effects that stem from internet usage. According to Nielsen, internet users continue to spend more time with social media sites than any other type of site. At the same time, the total time spent on social media in the U.S. across PC and mobile devices increased by 99 percent to 121 billion minutes in July 2012 compared to 66 billion minutes in July 2011 Popular Social Media Tools and Platforms Blogs A platform for casual dialogue and discussions on a specific topic or opinion. Face bookThe world’s largest social network, with more than 1.32 billion monthly active users (as of June 2014). For accessing users create a personal profile, add other users as friends, and exchange messages, including status updates. Brands create pages and Facebook users can â€Å"like† brands’ pages. WhatsApp WhatsApp is the best social network and mobile application. User create accounts send images videos audio notes update status, recently Facebook purchased it. Viber Viber is also an application and bestest application that gives both option of chat and call to the user.

LinkedIn GroupsA place where groups of professionals with similar areas of interest can share information and participate in conversations. VimeoVideo hosting and watching websites. Scenario 1 An example of digital social media, i.e. Face book. Facebook(formerly[thefacebook]) is an online  social networking service  headquartered in  Menlo Park, California. Facebook now allows anyone who claims to be at least 13 years old to become a registered user of the website. After registering to use the site, users can create a  User profile, add other users as  friends, exchange messages, post status updates and photos, share videos and receive notifications when others update their profiles. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as People from Work or Close Friends. Construct a finite automata for facebook in which a user first access to the login page of facebook then user enter ID and password for login process. This process work in backend due to searching algorithm and after search facebook opens the account of the user who enters the ID and password. And now user is entered in home page. If the user wants to create account on facebook then he/she have to enter some details that are required for creating an account and after verification of detail the user can use their home page. In home page there are 4 main options and many other option if the user wants to stay on the home page i.e. user may use search bar for searching any stuff, any application any friend or anything. User want to access a group that he already joined and either option. The 5 main options are: Newsfeed (notification) Sharing Profile Search Chat Now if user want to open newsfeed then user is able to see latest notification or anything in which user is tagged or anyone post on his time line or having response of the something which the user is already shared. User wants to share any picture/audio/video or any status among his friends. The other option is profile. Profile is the timeline of the user in which user can see or comment on what user have already shared or any friend have shared or commented on is shared thing or on status and user can update his/her personal information. The other option is search. The user want to search some content by using search bar. The last but not least option is chat. That enable the user to chat with the friends on his/her friend list. As the whole automaton of the facebook is too vast that’s why for describing them clearly we divided it into 2 states. The first state is login state and the other stage is after login stage. And at the end we will combine all the stages as final automata. STATE 1 (login state) L= {L, EN, P, H, CA, ED, V,} Q= q0, q1, q2, q3, q4, q5, q6, q7 Where, L=login EN= enter name P= enter password H=home page CA=create an account ED=enter detail V=detail verified The above automaton is illustrating that when the user give the input â€Å"L† means login and after â€Å"L† machine accepts the name and the password i.e. EN (enter name ) and p (password) for reaching the final stage of login state i.e. HOME. The user have another option if the user have not any account then the facebook machine (automata) also gives the opportunity to create an account for creating the account the machine accepts the particular details i.e. ED means to enter the required detail. In this automata it is defined that when user open the facebook user have 2 option either he/she open account or he/she creates new account. So if user have not his account so he follow the second option go to create option enter all the details then verified these detail and account created and if have user have already account so he he/she just enter name and password and enter these thing . So same as defined in this automata user have to follow two paths which are clearly mentioned in this automata. Regular expression for the state 1 STATE 2 (After login ) L= { H, SH, NF, Pr, S, CH, LO, D} Where SH = user wants to share the pictures/audio/video or text among his friends. NF = notification from the friends or the pages liked. The user can select the notification and see Pr= timeline of the user. In which user can see what he shared or he/she can update his/her information. S= the user want to search some contact. CH = it stands for chat. That it enables user to chat with the friend on his/her friends list LO = logout. The user sign out and get return to the main page Second state is describes is the state open after login so after login facebook is a multifunction social media but we compiled main functions. So when user logins to fb user have many options now depend on user what user wants to do. either user stays on home page and read normally or he shared any others post, or check the notification of other or the thing which he/she tagged in, or view his own profile or any others profile or use the search option to find any person or search any app or games for playing or using.†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ There are many others also things to do but these are the main thing which normally user can do on the daily basis. Now there are some other things also which we mention in automata is using keelene. It’s like if user logins the page and he do not do anything just stay remain in home page it’s not necessary that all user do the same so it’s also mention in automata. Regular expression for the state 2 It’s a general regular expression which is made by the automata but we have to normalize the regular expression fro make it simple and complicated for other so they don’t try to copy, After normalization I denoted as the r.e2 because it’s the same regular expression but just a normalized form. See transition table on the next page, Combined automata L= {L, EN, P, H, CA, ED, V, H, SH, NF, Pr, S, CH, LO, D } r.e = S (L.E.N.P.H + CA. ED. V. H) H*(SH+ + NF++ Pr+ +S++CH*)D(H+LO) Scenario 2 Another example of digital social media i.e., WhatsApp WhatsAppis a  proprietary,  cross-platform  instant messaging  subscription service  for  smartphones  and selected  feature phones  that uses the  Internet  for communic

Eulogy for Father :: Eulogies Eulogy

Eulogy for Father For the first time in my life, I'll celebrate Father's Day this year without my dad. The man who had the most influence on the man I became passed away on April 14. Jack was 79. It has been said that the loss of a parent is one of life's most traumatic events. I now know the devastating truth of that statement. I've been told that, in time, the hurt will fade, only to be replaced by positive memories that soothe the soul. Already, I can feel that happening. Maybe it's because my father and I had a simple and loving relationship. He was a remarkably good man, like many of the inspiring role models and mentors who frequently appear in Fast Company's pages. Like them, he was a person of devotion and integrity, a man who understood a hard day's work. Yet, unlike most of them, he never had the advantage of a college education. He worked pretty much his entire life in two places: a dye house and a post-office sorting facility. His core accomplishment was family. And as his only child, I was the lucky beneficiary. My father poured vast amounts of love and energy into me during my most formative years. That is why I measure his life in the warehouse of photographs and movies he created for me. It is why I measure it in the size of his hands. Because what I remember most about my father are those sandpaper-rough hands, made rugged from factory work. From my earliest days, he took my hand in his and we discovered the world together. With his hand in mine, we walked through New York's Times Square. We went to Tad's Steakhouse, where you could get a T-bone, a baked potato, a hunk of garlic bread, and a tossed salad for $2.79. We went to my grandmother's house on Saturday afternoons for endless games of gin rummy, Parcheesi, and Chinese checkers. We went for long hikes on Sunday afternoons, through the nearby woods. We hitchhiked together. We played music together -- he on a keyboard, me on a drum kit. We strolled the railroad tracks together in Paterson, New Jersey, laying pennies on the rails and waiting for the train to pass so we could use the flattened coins for guitar picks. We fished together, in rowboats, off riverbanks and bridges, in rivers and lakes, with worms and fish eggs, and lures and flies.

Firstly, I will focus on the time he wrote the story and than I will describe his life and his three major writing phrases. Next, I will go on with giving the most important of the story touching the most important point of its sources and who influenced James to such a work. The next section in the term paper is one of the most important ones because it touches all the most important things connected with fiction in James`s short story which will be a guide towards the analysis of Paste. In the analysis I will examine the narrative techniques and I will connect the discourse with the story. Finally, the term paper ends with an conclusion summing up all the relative points. 2. American Modernism The large cultural wave of Modernism, which gradually emerged in Europe and the United States in the early years of the 20th century, expressed a sense of modern life through art as a sharp break from the past, as well as from Western civilization's classical traditions. Modern life seemed radically different from traditional life — more scientific, faster, more technological, and more mechanized. Modernism embraced these changes. Technological innovation in the world of factories and machines inspired new attentiveness to technique in the arts. To take one example: Light, particularly electrical light, fascinated modern artists and writers. Posters and advertisements of the period are full of images of floodlit skyscrapers and light rays shooting out from automobile headlights, moviehouses, and watchtowers to illumine a forbidding outer darkness suggesting ignorance and old-fashioned tradition. The way the story was told became as important as the story itself. Form and structure became more important than content. Henry James, William Faulkner, and many other American writers experimented with fictional points of view. Vision and viewpoint became an essential aspect of the modernist novel as well. No longer was it sufficient to write a straightforward third-person narrative or (worse yet) use a pointlessly intrusive narrator. The way the story was told became as important as the story itself. 3. Henry James (1843-1916) [pic] Life: Henry James was born in New York City into a wealthy family. His father, Henry James Sr. , was one of the best-known intellectuals in mid-nineteenth-century America, whose friends included Thoreau, Emerson and Hawthorne. In his youth James traveled back and forth between Europe and America. From an early age James had read the classics of English, American, French and German literature, and Russian classics in translation. He studied with tutors in Geneva, London, Paris, Bologna and Bonn. At the age of nineteen he briefly attended Harvard Law School, but was more interested in literature than studying law. James published his first short story, A Tragedy of Errors two years later, and then devoted himself to literature. In 1866-69 and 1871-72 he was contributor to the Nation and Atlantic Monthly where his first novel, Watch and Ward (1871) was published. James wrote it while he was traveling through Venice and Paris. After living in Paris, where James was contributor to the New York Tribune, he moved to England, living first in London and then in Rye, Sussex. During his first years in Europe James wrote novels that portrayed Americans living abroad. James's years in England were uneventful. In 1905 he visited America for the first time in twenty-five year, and wrote ‘Jolly Corner'. It was based on his observations of New York, but also a nightmare of a man, who is haunted by a doppelganger. Between 1906 and 1910 James revised many of his tales and novels for the so-called New York Edition of his complete works. It was published by Charles Scribner's Sons. His autobiography, A small boy and others (1913) was continued in Notes of a son and brother (1914). The third volume, The middle years, appeared posthumously in 1917. The outbreak of World War I was a shock for James and in 1915 he became a British citizen as a loyalty to his adopted country and in protest against the US's refusal to enter the war. James suffered a stroke on December 2, 1915. He expected to die and exclaimed: â€Å"So this is it at last, the distinguished thing! † However, James died three months later in Rye on February 28, 1916. Two novels, The Ivory Tower and The sense of the past(1917), were left unfinished at his death. James`s three writing phases after his Biographer Leon Edel: James's first, or â€Å"international,† phase encompassed such works as Transatlantic Sketches (travel pieces, 1875), The American (1877), Daisy Miller (1879), and a masterpiece, The Portrait of a Lady (1881). James's second period was experimental. He exploited new subject matters — feminism and social reform in The Bostonians (1886) and political intrigue in The Princess Casamassima (1885). He also attempted to write for the theater, but failed embarrassingly when his play Guy Domville (1895) was booed on the first night. In his third, or â€Å"major,† phase James eturned to international subjects, but treated them with increasing sophistication and psychological penetration. The complex and almost mythical The Wings of the Dove (1902), The Ambassadors (1903) (which James felt was his best novel), and The Golden Bowl (1904) date from this major period. In James, only self-awareness and clear perceptio n of others yields wisdom and self-sacrificing love. Characteristic for James novels are understanding and sensitively drawn lady portraits; James himself was a homosexual, but sensitive to basic sexual differences and the fact that he was a male. His main themes were the innocence of the New World in conflict with corruption and wisdom of the Old. In James's later works, the most important events are all psychological — usually moments of intense illumination that show characters their previous blindness. Apart from writing fiction, James made important contributions to the genre of literary theories, especially through his famous essay, The Art of Fiction, 1884. g. In his early critics James considered British and American novels dull and formless and French fiction â€Å"intolerably unclean†. â€Å"M. Zola is magnificent, but he strikes an English reader as ignorant; he has an air of working in the dark; if he had as much light as energy, his results would be of the highest value. † (from The Art of Fiction) 4. Paste Two weeks after his fathers death Arthur Prime lost also his stepmother, an former actress Miss Bradshaw. After his stepmothers funeral Arthur told his cousin Charlotte to select and take some of the jewelry her aunt left. Charlotte selected a pearl necklace which seemed to her as real. Arthur felt deeply insulted with the thought that they were real and the way his stepmother as an actress could got such pearls. Charlotte apologizes and agrees with Arthur that they are paste and takes them s back to Bleet where she worked as governess. Once at a party, Mrs. Guy noticed the pearls, recognizes them as genuine and with Charlottes approval wears the string at the party. When Charlotte noticed that everybody at the party assumed they were real she insisted at the idea to return them to her cousine Arthur who still pretends to believe that they were pasteand later writes to her that he smashed them to destroy any false slur upon his family. Later however, Charlotte sees Mrs. Guz wearing a beautiful pearl string. She explained to Charlotte she bought it from a dealer to whom Arthur sold them. Charlotte was disappointed how her cousin could be so deceitful. The origin of â€Å"Paste† is rather more expressible, since it was to consist but of the ingenious thought of transposing the terms of one of Guy de Maupassant's admirable stories. The story originated from the idea of reversing the situation of de Maupassant`s La Parure, in which a supposedly genuine necklace is found to be false, by centering the action on a string of perals, thought to worthless but proved to be real. In â€Å"La Parure† a poor young woman, under â€Å"social† stress, the need of making an appearance on an important occasion, borrows from an old school friend, not much richer than herself, a pearl necklace which she has the appalling misfortune to lose by some mischance never afterwards cleared up. Her life and her pride, as well as her husband's with them, become subject, from the hour of the awful accident, to the redemption of their debt; which, effort by effort, sacrifice by sacrifice, excuses, a rage of desperate explanation of their failure to restore the missing object, they finally obliterate–all to find that their whole consciousness and life have been convulsed, that the pearls were an â€Å"imitation† and that their passionate apology has ruined them for nothing. According to Henry James and his theory of fiction Guy de Mauppasant holds that we have no universal measure of the truth and that there are many different classes of fiction which help us to understand that the particular way we see the world is our particular illusion about it. 5. Fiction in Paste and Henry James Henry James`s conception of writing fiction is defined in these words: â€Å"A novel is, in its broadest definition, a personal, a direct impression of life, that, to begin with, constitutes its value, which is greater or less according to the intensity of the impression. But there will be no intensity at all, and therefore, no value, unless there is freedom to feel and say. † In his treatment of subject matter, James felt that no aspect of life should be excluded. He said that â€Å"the province of art is all life, all feeling, all observation, all vision †¦ it is all experience. That is a sufficient answer to those who maintain that it must not touch the sad things of life †¦ † James's style of writing is magnificent and his canvas is broad – encompassing both Europe and America. He is a master of character portrayal and has extensively used the â€Å"stream of consciousness† method in his fictional writing. Julie Rivkin explains the term as a radiating luminous intelligence which integrated the â€Å"felt life† into fiction. Perhaps more than any previous writer, James refined the technique of narrating a novel from the point of view of a character, thereby laying the foundations of modern stream of consciousness fiction. Henry James produced one hundred and twelve stories and majority of them have been ignored or dismissed as a tributary to the mainstream of his novels. James creative energies were devoted equally into his novels, essays and his short stories, which means that also the stories deserved critical research as his novels or essays. James wrote about Guy de Maupassant that he will be remembered because of his more than hundred tales he wrote and not on his half a dozen novels meaning probably that he wanted to state that his whish would be to remember him himself also because of his novels and his short stories. 6. Paste analysis Henry James is grappling with the idea of keeping the story under 7,000 words. Part of this struggle develops from his idea seemingly having too much to say, but the notebook entry also leans towards the difficulty of being able to create a diverse enough idea to actually have a story within this space. James seems to be attempting to begin answering what is the short story: â€Å"†¦but to do anything worth while with it I must †¦ be very clear as to what it is in it and what I wish to get out of it. †¦ It must be a picture; it must illustrate something. † This also refers back to that that the writer needs to avoid a simple summary of events and the reader must encounter a story within the sketch structure. Within James’ description of the story he intends to work on, he places a great deal of emphasis on contrast to relay his story. Paste is one of the few tales in which James successfully approaches Maupassant`s technique, allowing the objective action of the tale to reveal all its characters and values. The plot is swiftly set in motion, on the day of his stepmothers` funeral , Arthur allows his cousin Charlotte to take one peace of stage jewelry, she picks out some paste pearls which she honorably returns to Arthur when she founds out they are real. Arthur being a prudish stepson is greedy enough to sell the pearls , while he wrote her cousin he destroyed them. As so often in this tales, the professional virtuous are exposed as utterly fraudulent and the decent people as Charlotte as selfless fools. Only Mrs. Guy which with her name remembers us on Guy de Maupassant is one of James`s innumerable versions of the Madame Merle- type competent wordly woman with an innocent look and a strong authority manages to a short while to win the reader`s thoughts. Paste is told by an omniscient third-person narrator, who refrains from judging the characters or their actions. The narrator does have access to the characters' thoughts, but for the most part, the narrator simply describes the events of the story, leaving it up to the reader to determine the nature of the characters through their actions. Most of all, the narrator is concerned with Charlotte Prime. The moral dimension is most obvious in what appears to be James`s confident insistence on the reality of moral evil, motivated by egoism and by self-sacriface, especially sacrifice of own happiness. Charlotte insisted on the problem of sacrifice and she does not act for her own good, she wants to be fair and returns the pearls to her greedy cousin and when she founds out that he sold them she asks her self why was she so moral and truthful James`s characters, especially Charlotte, are presented as they having a very difficult time to simply trying to understand what they most need to understand- their own and others intentions or motives. The major themes in the story are paste, greed, losing moral values, truth vs. lie. All the themes are connected with a symbol in the story. Paste meaning the farce which Arthur plays toward his cousin, implying that things are not always what they seem to be. All the themes are connected with transition from innocence and naivety to experience. Development of Charlotte Prime in Paste Charlotte Prime is a governess in a little town called Bleet and the role of a governess in Victorian times was not a popular figure in Victorian England. The governess did not have a social position worthy of attention. The problem existed in them that aristocrats and middle-class Victorians were not sure how to treat the governess because she was in many cases also from the same class as they were, but her lack of financial stability made them view her as she were from the lower class. To work as a governess in Victorian times was justified by the society only if she found herself in financial distress or had no relatives to give her support. From the story it is noticeable that Charlotte Prime was also working as a governess because her bad financial situation 6. Conclusion The main aim of this research paper was to show how James dealt with fiction in his short stories, especially in Paste. James was fascinated to be challenged with writing short stories. He knew that had to take one single incident and his fiction does not generally lend itself to a close examination or its values are diffuse, the structure is often loose, its effects depend on stock devices and responses. That means that a plot need be no more than a string of stock devices for arousing stock responses of concern and excitement in the reader. The reader’s interest may be captured t the outset by the promise of conflicts or mysteries or frustrations that will eventually be resolved, and he will gladly—so strong is his desire to be moved or entertained—suspend criticism of even the most trite modes of resolution. 7.

Suicide rate in prison Essay Example

Suicide rate in prison Essay Example Suicide rate in prison Essay Suicide rate in prison Essay Essay Topic: Blankets Prison inmates have a higher suicide rate than those in the general community.   In the US, research shows that for inmates housed in pretrial facilities, the suicide rate is ten times that of the outside community (World Health Organisation 2000).   In facilities accommodating sentenced prisoners, the suicide rate is three times greater than in the outside community (World Health Organisation 2000). Additionally, it is worth pointing out that for every successful suicide attempt, there are numerous more unsuccessful suicide attempts (World Health Organisation 2000).   Suicide rates in prison have steadily increased over the decades. In the US, the number of inmates who take their own life has overtaken and now more than doubles the number of inmates that are killed by other prisoners (Wortley 2002).   In 1990, 134 inmates in US prisons committed suicide.   In 1995, the number rose to 169 (Stephan 1997).   In the UK, the number of suicides in prison was 37 in the year 198 8, and rose to 82 in 1998 (HM Chief Inspector of Prisons for England and Wales 1999: 12).According to Hayes (1995), one of the most constant findings in his research was that suicide rates are highest among smaller prison systems.   This finding, Hayes argued, reflects the lack of resources that smaller prisons tend to have.   This finding obviously shows that the prison environment is an important factor implicated in prison suicide.Research shows that hanging is the most common manner in which inmates commit suicide.   In a British study, 90 per cent of inmates committed suicide by hanging themselves, 4 per cent did it via poison or drug overdose, 3 per cent via cutting themselves, and 1 per cent via smoke inhalation or burns (Dooley 1990).   These figures are similar to those found by Hayes (1995) in the US, who found that 96 per cent of inmates committed suicide by hanging themselves, and the rest did it via cutting themselves or ingesting drugs. Similarly, White and Sch immel (1995) found that 79 per cent of prison suicides were done by hanging, 7 per cent by jumping to their deaths, while drug overdose, shooting and cutting accounted for 5 per cent each.Research conducted on attempted suicide shows that the most common way inmates attempt, unsuccessfully, to kill themselves is by cutting or slashing their wrists.   Inch et al (1995) found that 64 per cent of inmates attempted suicide by cutting, 32 per cent by hanging and 4 per cent by swallowing a sharp object.According to Hayes and Rowan (1988), the statistics for specific instruments involved in prison suicide are as follows: 48 per cent of inmates use bedding, 34 per cent use clothes, 5 per cent use shoelace, 4 per cent use towels, 2 per cent use belts, and 1 per cent use guns.   The rest of the instruments utilized in prison suicide are knives, razor blades, drugs, glass, and knives, however these account for only 1 per cent each (Wortley 2002).Who commits suicide in prisonAn analysis was made of 52 suicides in New York prisons between 1986 and 1994 (Hayes 1995).   The analysis revealed that white inmates, who represented 18 per cent of the prison population, accounted for 42 per cent of the suicides.   In comparison, black inmates represented 50 per cent of the prison population, but accounted for only 20 per cent of suicides (Hayes 1995).   Further, this study found that while inmates condemned for violent crimes represented   56 per cent of the prison population, they accounted for 80 per cent of suicides.   With respect to length of incarceration, 64 per cent of all victims committed suicide within 2 years of incarceration. 66 per cent of the victims had mandatory minimum sentences of at least 4 years, and 23 per cent of victims were serving life sentences (Hayes 1995).Inmates under 21 years of age are more likely to commit suicide than older inmates (Worltey 2002).   According to Wortley, younger prisoners tend to react more intensely and more impul sively than older prisoners.   Another explanation for the higher rate of suicide among young prisoners could be that bullying and harassment are greater in prisons with larger numbers of youths (Wortley 2002).   Additionally, Dooley (1990) found that occurrences of suicides in prisons with high youth populations had the effect of inciting other young prisoners to imitate the behaviour.CausesSocial isolation is regarded by psychologists as the most important cause of suicide (Berman, 2007).   It is not surprising therefore, that the prison environment, being one of loneliness, deprivation, hardship, and isolation from their friends and family, has a strong influence in prison suicide victims and can offer an explanation to the higher suicide rate in prisons.Modern psychologists have described several common characteristics found in suicides.   These include a sense of unbearable psychological pain, a sense of isolation from others, and the opinion that death is the only solu tion to problems for which a person feels hopeless and powerless (Berman 2007).   One would think that an environment such as that found in a prison would seem to foster those very feelings in their inmates.Mental health problems are also believed by experts to be a major factor in suicides (Berman 2007).   Not surprisingly, a relatively high incidence of mental-health problems is found among prison suicide victims.   According to White and Schimmel (1995), in a study conducted on 43 suicides, 23 victims had a prior psychiatric diagnosis, including 11 diagnosed with severe psychotic disturbance, 6 with affective disorder and 4 with paranoid ideation.   17 of the victims had previously attempted suicide at least once (White Schimmel 1995).At the same time, the evidence suggests that there is a direct relationship between prison suicide and the experience of being in prison (Wortley 2002).   A previous record of psychiatric treatment is less likely for prison suicide victim s, than for suicides of the general community.   In research conducted by Liebling, et al (1999), the percentage of prison suicide victims with past psychiatric treatment was 33 per cent, and the percentage of suicide victims in the general community with past psychiatric treatment was 80 to 90 per cent.   This once again suggests that the prison environment itself plays an important factor in prison suicide.According to Wortley, 30 per cent of inmates who had attempted suicide said the reason for doing so was threats or teasing by other inmates, 24 per cent said that it was because they had been punished or placed in segregation, 22 per cent said that their sentence was longer than they expected, 12 per cent had received or were expecting to receive a letter from a loved one, 8 per cent had received an unwanted transfer, and 4 per cent had had their parole rejected. White and Schimmel (1995) found that the most common factors were new legal problems (28 per cent), relationship problems (23 per cent) and conflicts with other inmates (23 per cent).Security levelResearch has shown a greater number of suicides and attempted suicides in maximum security prisons than in medium and minimum security prisons (White Schimmel 1995).   A possible reason for this could be than maximum security prisons are more disheartening and gloomy, or it could be that maximum security prisons house more suicide-risk inmates. In any case, this shows that the additional restrictions and observations that occur in maximum security prisons are not enough to prevent inmates from killing themselves (Wortley 2002).Stage of sentenceOne of the most constant results with respect to prison suicide is that the risk is greater while prisoners are on remand or in the early stages of their sentence (White and Schimmel 1995).   Over 50 per cent of jail suicides occur within the first 24 hours of incarceration, and 26 per cent occur within the first three hours (Hayes 1995).   In prison, 17 per cent of suicides occur within the first week of incarceration and 51 per cent within the first three months (Dooley 1990).   Obviously, the first months in prison are the hardest and the most difficult to cope with, and this can push some inmates over the edge.There is also evidence of a relationship between time served and suicide.   Prisoners with sentences over twenty years seem to have a higher suicide risk.   In one study, this group accounted for 28 per cent of suicides but represented only a 12 per cent of the prison population. (Wortley 2002).   It is reasonable to concur that the high prison sentences most likely gave the inmates a deep sense of hopelessness.This paper will now proceed to outline several strategies to prevent prison suicide.Prevention of Prison SuicideIncreased visitation rightsAs previously mentioned, feelings of isolation from family and friends is a key factor in suicides.   It is beneficial to prisoners that they have adequate visiting ar rangements and facilities in order for them to not feel so isolated.   These visits are important because it would provide much needed emotional support that may protect inmates from despair and irrational thinking during their difficult times in prison.   If the prisoner can make physical contact with his loved ones this would be even better (Reser 1992). These visits can be of special significance to some cultural groups, as some research has identified lack of family contact as the crucial factor in prison suicides among some cultural groups such as Australian Aborigines (Johnston 1991).Increasing guard patrols and surveillanceA successful surveillance regime in prisons, with regular guard patrols and close-circuit television, can lower suicide rates in prisons.   Hayes reported on a successful suicide prevention regime in a US prison in which close-circuit television and physical checks were conducted at least every five minutes, depending on an inmates suicide-risk level.    Additional random checks were made so that inmates could never predict them and so had no opportunity to kill themselves.   The result of this regime was that over a 12 year period, only one suicide occurred among 57,000 processed inmates (Hayes 1995).Cell designTo prevent suicide, something should be done about the design of windows and doors so that they are unable to be utilized as hanging points.   Similarly, the design of ventilation covers and light fixtures should be altered so that they cannot be used as hanging points (Atlas 1989).   Metal door bars should be replaced with polycarbonate glazing; light fixtures and ventilation covers should be covered with tamperproof screen; exposed pipes, brackets, hinges, knobs and electrical outlets should be eliminated.   Additionally, to help elevate the depressing mood in prison cells, cells should have access to natural sunlight and be painted in pastel rather institutional colors (Atlas 1989).Role of staffStaff should b e appropriately trained in suicide prevention, and strategies to prevent suicide should be carefully outlined in prison policy documents and given to staff. There is a need to provide staff with the necessary information about suicide and suicide prevention.   Staff should be made aware of the signs of suicide-risk inmates and the appropriate protocols for dealing with suicide-risk inmates.   Inappropriate staff attitudes such as that nothing can be done to stop a suicidal inmate, or that suicide attempts are meant only to get attention, should be done away with.   Any sign that suggest that an inmate could be suicidal should be taken seriously (Wortley 2002).Restriction of dangerous itemsThe instruments used to commit suicide in prison are those that are easily available to inmates.   Hanging with the use of clothing and bedding, is the most common way in which suicide is accomplished.   Together with the elimination of hanging points, suicide by hanging can be reduced wi th the use of tear-resistant sheets and blankets (Wortley 2002).   The restriction of razor blades, and other objects that could be fashioned to inflict self-harm is obviously another way in which prison suicides could be prevented.   The main task here lies in identifying which items prisoners can utilize to harm themselves, which is not always easy to accomplish as prisoners in the past have imaginatively used what one would think were harmless items, such as toothbrushes, to commit suicide (Wortley 2002).ConclusionHigh prison suicide rates are a worldwide phenomenon.   Several causes for this have been suggested, but perhaps the most relevant is the prison environment itself which drives vulnerable inmates, especially younger the inmates, into committing suicide.   The strategies presented in this paper for preventing prison suicide could be utilized to control prison suicide rates.   The control and lowering of prison suicide rates is important, as suicide has a devast ating emotional impact on surviving family members and friends of suicide victims.ReferencesAtlas, R.

The iroquois and the US constitution essays

The iroquois and the US constitution essays Nothing is so fundamental yet so important to the freedoms we enjoy as Americans as the United States Constitution, which guarantees our right to do and say as we please so long as it does no harm. The Iroquois Federation preamble describes the purpose of the government set up by the government in their statements the emphasis is placed on perfect peace for the welfare of the people. Their focus was fighting for, the liberty of the people. Among the Indian nations whose ancient seats were within the limits of our republic, the Iroquois have long continued to occupy the most conspicuous position. The Iroquois flourished in independence, and capable of self protection, long after the new England and Virginia races had surrendered their jurisdictions, and fallen into the condition of dependent. Nations they now stand forth upon the canvas of Indian history prominent alike for the wisdom of their civil institutions of the league. Only the Iroquois had a system that seemed to meet most of the demands espoused by the many parties to the debates the Iroquois certainly have a considered the influence on the drafty of our own constitution, and we present day Americans owe them a very large debt. At the time of the founding of Iroquois League of nation, we have only the early stories, which was passed down from generation until such time as a written language existed. We only have stories that were passed down form generation to generation until such time as there was a written language and interprets available to record that early history. Early explores and colonist found the Iroquois well establish as they had been for many generations with a democratic government, with a form at religion that acknowledged a creator in heaven; with a strong sense of family which was used on, and controlled by their women. In 1744 an Iroquois leader, Canassatege, had an idea. In presenting the idea to his assembly, he realized that no one was ...

Present Simple Exceptions in English Grammar

Present Simple Exceptions in English Grammar Here is the most important English language rule to remember: Almost every rule is about 90% valid. As confusing as that concept may be, it is certainly one of the most frustrating and truthful things about learning English. All that hard work to learn the correct grammar and then you read or hear something like this: Peter does want to come this summer. Its just that he cant get off work. As an excellent student, the first thought that comes to your mind is; wait a minute, that first sentence is a positive sentence.  Does want  cant be correct. It should be; Peter  wants to come this summer. Of course, according to what you have learned you are correct. However, in certain instances, you can use both the auxiliary and principal verb together to form a positive sentence. We allow this exception to add extra emphasis. In other words: Peter really wants to come this summer. Exceptions to the (English) Rules This feature will concern the various uses of and exceptions to the simple present. You all know that we usually use the simple present to express: Habitual actionsOpinions and preferencesTruths and facts You also know that the standard construction is the following: Positive: Tom goes to the beach on SaturdaysNegative: Mary doesnt like to eat fish on Fridays.Interrogative: Do they work in New York? Here are some simple present exceptions/extra possibilities. Exception 1 In order to add stress to a positive sentence, we can use the auxiliary verb to do. We often use this exception when we are contradicting what someone else has said. Example: A: I dont think Peter wants to come with us this summer. He told me that he wouldnt be able to come, but I think he just doesnt want to come with us. B: No, thats not true. Peter  does  want to come. Its just that he has too much work and cant get away from the office. Exception 2 The simple present can also be used for the future. We use the simple present to express future, scheduled, events with verbs that express beginning and end, or departure and arrival. Example: A: When does the train for Paris leave?B: It leaves at 7 tomorrow morning. Exception 3 We use the simple present in time clauses when talking about future events. The  when  is expressed with the simple present. The  result  is expressed with a future form, usually the future with will. Time clauses are introduced by time signifiers such as when, as soon as, before, after, etc. The construction is the same as the first conditional except that we use a time signifier such as as soon as instead of if. Example: A: When are you going to come and see the new house?B: We will come as soon as we finish the Smith project. Exception 4 We often use the simple present when we write timelines or biographical outlines even if all the events take place in the past. Example: 1911 - Pete Wilson is born in Seattle, Washington.1918 - Pete begins to play the saxophone.1927 - Pete is discovered by Fat Man Wallace.1928 - Fat Man Wallace arranges Petes first concert with Big Fanny and the Boys in New York.1936 - Pete goes to Paris. Exception 5 In the question form, we usually use the auxiliary verb to do. However, if the question word/words (usually who, which or what) express the subject and not the object of the sentence, the question is asked using positive sentence structure with a question mark. By the way, this is true of other tenses as well. Example: Regular: Who do you work with? (some people prefer Whom do you work with?)Exception: Who works with you? Regular: Which toothpaste do you use?Exception: Which brands of toothpaste use fluoride? Exception 6 Time words cause a great deal of confusion to English learners. Here are some exceptions concerning time words. Adverbs of frequency such as regularly, usually, normally, always, often, sometimes, never, etc. are generally put before the main verb. However, they can also be put at the beginning or end of a sentence. Example: Regular: John usually arrives home at 5 oclock.Also possible: Usually John arrives home at 5 oclock OR John arrives home at 5 oclock usually. Note: Some teachers do not consider the other possibilities correct. However, if you listen carefully to native speakers, you will also hear these forms used. Exception 7 The verb to be also causes special problems. If the adverb of frequency is placed in the middle of the sentence (as is usually the case) it must  follow  the verb to be. Example: Regular: Fred often eats in a bar and grill.To be: Fred is often late to work. Exception 8 This is one of the strangest uses of adverbs of frequency. Negative adverbs of frequency used in the initial position of a sentence must be followed by question word order. These adverbs include  rarely, never,  and  seldom. Example: Regular: Patricia rarely finishes work before 7 p.m.Initial placement: Seldom does John play volleyball. The above exceptions are certainly not the  only  exceptions, however, they are some of the most common ones that you will encounter in your English language-learning journey.

Personal Statement Example It is through family that I have learnt to invest in simple things such as happiness and respect, prerequisites to every good life. Playing Persian drums requires both physical and mental skills. Physically, one need to develop a listening ear, it is through listening that one learns how and what to play. Any missed part means a lost rhythm which waters down the efforts of other instrumentalists and that of the lead singer or singers. Secondly, one needs a sense of rhythm and timing, one has to identify a rhythm fast enough to be able to play and aid the other performers. This also means that as a Persian drummer you have to have a fast response in order to coordinate well with the rest. The last physical skill is hands and feet coordination. One has to be able to coordinate their hands and feet to create the required rhythm. This level of coordination should be top notch to ensure a stable rhythm through out a performance. Physical skills and engagements may spell one’s prowess on the drums; however, it is the mental skills that allow one to develop the requisite physical skills. The most important mental skills are: a positive mindset, self-discipline and patience. A positive mindset helps one’s patience and resilience as they learn how to play drums. This is because it is a process and without a positive mindset then one will undoubtedly give up. Self-discipline is also another skill this is greatly informed by a positive mindset. Self-discipline ensures that a drummer becomes committed to his act and manages his time well to provide adequate time for practice. Just like in any other engaging activity, patience is paramount. One has to continually resist the urge to walk before one can crawl, a drummer must learn to make the small steps which ultimately build up the necessary skills. As evident, playing Persian drums is an involving engagement. Taking the learning process and being able to stay focused has required a lot of determination. Thankfully,

Furthermore, through eradicating pace in slow working will be to the advantage of the employer and employee. Reason being, it will lead to increased outputs for both men and the machine. With regard to clear facts, the existence of maximum prosperity depends on employees’ daily attendance. However, the main causes of men deliberately underperforming results from fallacies, faulty management system, and inefficient rule-of thumb method. The old management systems emphasized on allocation of final responsibility to workers with minimal advice and help. However, according to scientific laws, the management ought to be tasked with the responsibility of overseeing operations of a company. Consequently, this motivates the worker to perform their roles much better than they would have done. Beneath the management of incentive and initiatives, the entire problem associated with management is up to the worker. On the other hand, within the context of scientific management part of the problem is up to the management. The purpose of the study was to present the fundamental aspects involved in scientific management. The author’s point of argument is that the main purpose of management is safeguarding the maximum prosperity for both the employers and employees. Furthermore, the author asserts that maximum prosperity for both the workers and the employers should be the leading factors of management. In addition, the author believes that even though disagreements between employers and employees are rampant (due to the existing perception that the two factions cannot unit) he is confident that the two are the same. Therefore, they need each other for prosperity of both employees and employers. Lastly, the writer purports that within the management context problems experiences involves the worker while under scientific

Furthermore, the influence of social media on career choices in PR and media will be given an in-depth analysis. An overview of the unit represented three related think pieces. There was a one press release exam in which we all read the article and examined on the content. The unit featured a class debate in which the topic was â€Å"50 should Be the Cut off Age for Women to Have Children†. The unit was interesting and represented a personal interaction with the real issues affecting us. The press release exam concerned on a recent event that took place while the debate gave the real issue affecting women in the society. The lecturer was had vast knowledge and ready to listen to us. He would joke and make us laugh breaking the boredom. At times, he would allow us to stretch. His philosophy was that learning should not be difficult but rather made easier for students to understand. He always reminded us to remain practical at all times since the world out there needed people with our abilities. Some of the advices given by the lecturer influenced our learning both at the personal and class level. Since the unit had some level of difficulty, we decide to come together and form a class discussion for one minute session. It was difficult when coming up with the idea. Most of the students did not support the idea, but I insisted that it was appropriate we form a one minute session for the class for deliberating. I had to convince a rebellious friend to understand that it was for our common good. The lecturer was not strict in terms of the approach to the unit. He required 100% class attendance, and submission of while observing the deadline. He reminded us that in life it is important to make personal choices that we would never regret. With like-minded friends, we made it our decision to form the one minute session. Forming a one minute session helped in deliberating on the

Do European Works Councils represent a major advance in employee Essay

Do European Works Councils represent a major advance in employee representation - Essay Example countries with central management of large multinational companies to discuss issues as complex as worker rights and any plans the company may be considering that would affect workers. Meetings also allow employees of one country to share information and experiences with colleagues from other nations. â€Å"Employee participation at a European level became a reality with the introduction of the European Works Council Directive† (Fitzgerald, 2004: 1). The purpose of the Councils: to provide workers within large multinational corporations, through their designated representatives, a direct line of communication to top management. With communication as key, various national councils insure that workers in all countries are provided accurate information about plans and policies of the transnational companies who employ them, and ensure worker representatives of established unions and national works councils the opportunity to consult amongst each other and develop a common response before policies and plans are implemented. Beyond these goals, three main views about why works councils primarily exist include benign goals as stated to improve communication and less benign goals of worker control over bargaining and negotiations and input into company policy when market failures occur that may negatively impact their employment. Based purely on description of purpose, the formation of the councils appear a valid and reasonable response to the advent and power of multinational corporations—impersonal behemoths larger than life with little sense of employee conditions or problems experienced at lower management levels. The success of the councils as regards employee representation is, as might be expected, mixed. This paper examines the reality of the success or failure of the councils, and to what degree they have advanced the cause of worker representation. Fitzgerald (2004) points out that the EWC Directive in its final form was viewed as a watered-down version of

Motivating Employees and Self-Managed Teams Essay

Motivating Employees and Self-Managed Teams - Essay Example As a state of mind, Bruce and Pepitone described this as the attitudes and perceptions of individuals manifesting in the willingness to contribute greater effort towards the achievement of organizational goals with the willingness conditioned by expectation of satisfying individual objectives (2). State of mind depends on various factors. Nickels and McHugh identified these factors as scientific management (260) in organizations, the Hawthorne effect with perceptions of organizational concern towards employees linked to positive outcomes (262), a work environment meeting an individual's hierarchy of needs (263), existence of positive incentives and challenges (269), and intrinsic and extrinsic factors influencing job satisfaction (265). As a process, Bruce and Pepitone described motivation as the process of arousing, directing and maintaining attitudes, behavior and perceptions towards the attainment of organizational goals (2). Nickels and McHugh discussed motivation as the facilitation of the interaction between individual and organizational goals (273) in a manner that ensures the achievement of individual and organizational expectations (274) and perceived as fair (275). ... Motivating individual employees is important to the business environment because this creates a number of benefits. First benefit is job satisfaction (Nickels and McHugh 260), which refers to the positive emotional condition of employees that comes from their personal appraisal and/or organizational performance assessment of accomplished tasks. Job satisfaction means employees feeling better about the value of their work contribution to the organization, going beyond minimum expectations, and positive response to task completion. This is important in the contemporary business environment because of its link to customer service and satisfaction. Satisfied employees are likely to do better in their work. This spills over to their treatment of customers. Customers then receive better service and improved experience of the products and services of the firm (Nickels and McHugh 260). This could lead to repeat purchases and even loyalty. Second benefit is improved individual performance, which when combined translates into improved organizational performance (Bruce and Pepitone 38). This links employee performance and organizational performance. Employee performance refers to both work outcomes and task completion processes. Measurement of work outcomes could include task completion based on quotas or other standards applied by the organization. Efficiency in task completion by working with errors at a minimum level, targeting more than the minimum expectations, and better disposition towards work also reflect the performance of motivated employees. Improved individual performance is important to the contemporary business environment because

Approaches to Exceptional Psychology Essay Example for Free

Approaches to Exceptional Psychology Essay Psychoanalysis and psychodynamic therapies are possible in intervention for hydrocephalus. This approach focuses on changing problematic behaviors, feelings, and thoughts by discovering their unconscious meanings and motivations. Psychoanalytically oriented therapies are characterized by a close working partnership between therapist and patient. Patients learn about themselves by exploring their interactions in the therapeutic relationship. While psychoanalysis is closely identified with Sigmund Freud, it has been extended and modified since his early formulations. Psychoanalytic therapies have a strong research base confirming their efficacy. Hydrocephalus is usually the result of another medical problem within the skull. Medical interventions of hydrocephalus usually include a surgical shunt or medication or both. Therapist and patients should have a good relationship with each other. Cognitive approach Cognitive approach can be either applied in hydrocephalus intervention. Cognitive therapy emphasizes what people think rather than what they do. Cognitive therapists believe that its dysfunctional thinking that leads to dysfunctional emotions or behaviors. By changing their thoughts, people can change how they feel and what they do. The therapist role is to strengthen and encourage the families of the client that there is still hope inspite of the unwanted condition. The therapist can change the mindset of the client and the families of the client to still look in the positive outlook of the situation. While there is no cure for this ailment, there are still two surgical treatment that can be applied to Hydrocephalus. These are Shunt Placement and Third Ventriculostomy. Shunt Placement diverts the flow of cerebrospinal fluid (CSF) from a site within the central nervous system (CNS) to another area of the body where it can be absorbed as part of the circulatory process. For some people, hydrocephalus treatment can be performed using an alternative procedure called third ventriculostomy. With this option, a neuroendoscope(a small camera designed to visualize small and difficult-to-reach surgical areas)allows a healthcare provider to view the ventricular surface using fiber optic technology. The scope is guided into position so that a small hole can be made in the floor of the third ventricle, allowing the CSF to bypass the obstruction and flow toward the site of resorption around the surface of the brain. Approaches to treating hydrocephalus are both patient-focused and family-centered. Therapist should never lose sight of the fact that the client is , first and foremost, an individual—not merely a patient.

Methods of Lipid Analysis in Food

Methods of Lipid Analysis in Food Lipids are defined as the biomolecules whose solubility in water is less than that in non-polar solvents. This definition puts structurally distinct classes of compounds such as fatty acids, terpenes, steroids, prostaglandins and carotenes in the same class (Carey Giuliano, 2014). Other definition for lipid has also been suggested (Eoin, et al., 2005). They perform a variety of functions in living system including but not limited to structural integrity, energy storage, digestion and communication (Nelson Cox, 2005). Although lipids are essential for many body functions, not all lipids are required in same amount. Food and Agriculture Organization (FAO) recommends that total fat of the food contribute to 20-35% of energy for adults. This should include 8% saturated fatty acid(SFA), 11% poly unsaturated fatty acid (PUFA) and less than 1% trans fatty acid (TFA) (FAO, 2010). Chances of insulin resistance is more in overweight person in high SFA diet (Lovejoy, et al., 2002). Similarly, excessive TFA intake also increases the risk of cardiovascular disease (Song, et al., 2015). Fat content also affects taste. It is proposed that fat has a unique taste Oleogustus that is dependent of chain length and is unique from five conventional tastes: sweetness, sourness, bitterness, saltiness and umami (Running, Craig, Mattes, 2015). Butter produced from milk with high unsaturated fatty acid (UFA) was found to be more spreadable, softer and less adhesive (Bobe, Hammond, Freeman, Lindberg, Beitz, 2003). As the fat content and type effects health as well as taste and texture, it is essential to know the fat content of food. Fat sample is characterized by a variety of criteria and methods. The selection of the criteria and method depends upon the sample type, purpose, accuracy, precision, legal requirement as well as available funds. Hence, despite having limited significance for nutritional purpose, total lipid (TL) measurement is widely carried out as many food labelling regulations require the TL report. Similarly, iodine value can be used for unsaturation study when sophisticated chromatography or spectroscopy methods are unavailable (Greenfield Southgate, Review of methods of analysis, 2003). This review intends to compile the available methods of lipid analysis of food products. Focus will be given on the type of sample required, result provided, resolving capacity of each criteria and method. Only brief discussion will be done on the theoretical and experimental process of the method. Sample preparation is very essential part of analysis of lipid sample. A separate section is dedicated to sample preparation.          In order to analyze the lipid, suitable sample must be prepared. If the sample has lipid inside cells (such as meat) the lipid should be extracted from the cells (Christie Han, Lipid Analysis, 2012). Samples must undergo some pretreatment before they can be used as test sample. Depending on the nature of sample one or more of the following work is necessary. 2.1. Storage Vessel Plastic container should be strictly avoided to store lipids. Plasticizers can leach into the sample and contaminate it. Glass vessels or Teflon coated vessels should be used. The atmosphere should be argon or nitrogen to prevent oxidation. (Christie Han, Lipid Analysis, 2012) 2.2. Protection from Oxidation Unsaturated fatty acids are prone to oxidation from atmospheric oxygen. Once the oxidation starts, autocatalysis accelerates the process. Different products are formed during oxidation and it may follow various mechanisms. Light, heat, metals, enzyme are known to catalyze the reaction (Angelo, 1996) Oxidation interferes with lipid analysis not only by destroying the unsaturated fats but also by formation of conjugated double bonds which show strong absorption at UV, thus providing false positive results (Christie Han, Lipid Analysis, 2012) Elimination of oxygen is the major step in prevention of oxidation. Therefore, all steps should be done in nitrogen atmosphere as far as possible. Equipment should be flushed with nitrogen before experiments. Small amount of antioxidant like 2,6-di-tert-butyl-p-cresol, which do not interfere with analytical process, may be added. Excess of these antioxidant should not be used as they can facilitate oxidation in high concentration. (Christie Han, Lipid Analysis, 2012) 2.3. Drying of Sample Lipid sample containing water can make analysis difficult and might be a source of error. Solvents cannot penetrate sample with >8% moisture easily. Hygroscopic solvents like diethyl ether can absorb the moisture, decreasing its extraction efficiency. Low moisture also facilitates grinding and increases the surface area of sample (Shahidi Wanasindara, 2008). Petroleum spirit, the most widely used solvent requires completely dried sample. (Greenfield Southgate, Review of methods of analysis, 2003) Depending on the type of water present (free, adsorbed or water of hydration) different methods may be required for water removal (Bradley, Jr, 2010). Care should be taken during drying as high temperature might lead to decomposition and combination of lipids with other components. These associated lipids cannot be extracted by solvents. Lyophilization (freeze-drying) and vacuum drying methods are preferred drying methods. (Shahidi Wanasindara, 2008) 2.4. Particle size reduction (Grinding) Solid food sample might need grinding. Grinding increases the surface area and decreases the length through which solvent need to penetrate the sample (Min Ellefson, 2010). Care should be taken that the particles are not too fine, too much heat is generated or too much moisture is lost. (IUPAC, 1979) 2.5. Hydrolysis Lipids in food may be bound ionically or covalently with non-lipid components such as carbohydrate or protein. Solvents are not able to extract them efficiently. Therefore, lipid needs to be hydrolyzed with acid or alkali to turn them into free state. Significant error in lipid extraction is reported when no hydrolysis is carried out. (Min Ellefson, 2010) Hydrolysis also breaks emulsified fat. (Shahidi Wanasindara, 2008) Acid hydrolysis is used for most foods except diary and high sugar content food which require alkaline hydrolysis. Hydrolysis is not preferred when the lipid extract needs to be further analyzed for fatty acid components because they can cause decomposition and oxidation of the sample components. (Greenfield Southgate, Review of methods of analysis, 2003) The given sample of food might not be entirely lipid. The amount of lipid in the food sample is called total lipid concentration. It is usually expressed as percentage or per 100gm food (Moreau, 2005). Although total lipid is widely used for food labelling and regulation of food composition, it has limited value as it does not provide the type of molecule in the lipid. (Greenfield Southgate, Review of methods of analysis, 2003) There are various methods to determine total lipid in food like solvent extraction, non-solvent extraction, instrumental methods. The selection of methods depends on a number of factor which is discussed below. 3.1. Solvent Extraction In solvent extraction, the lipid component of the food is extracted by dissolving in suitable organic solvent(s). The solvent selectively dissolves the lipid while leaving the non-lipid portion undissolved. The solvent is then evaporated to leave fat residue. Total lipid is then determined gravimetrically as: -(i) The above data gives the total fat. However, a significant portion of the fat includes glycerol (from triglycerides) phospholipids and other unsaponifiable matters. Thus, corrections are required so as to represent the correct amount of fatty acids in the sample. The correction factor is provided by FAO. (Greenfield Southgate, Appendix 5, 2003) The extracted portion of solvent extraction is highly dependent on solvent use. Hence selection of solvent is discussed in detail next. Solvent Selection Ideal solvent should extract all lipids and lipids only. However, due to wide range of polarity of different lipid types, no single solvent can provide an ideal solution. Moreover, the solvent selected should preferably be low boiling, non-flammable, non-toxic in liquid as well as solid, easily disposable after extraction, inexpensive and non- hygroscopic. It should also penetrate sample thoroughly (Min Ellefson, 2010). Petroleum ether is the most commonly used solvent for its selectivity towards lipid, cost and availability. However, diethyl ether is better solvent for lipids but its fire hazard and hygroscopic nature makes it less favorable than petroleum ether. Ethyl ether and petroleum ether is also sometimes used alternately or together for extraction. (Pomeranz Meloan, 1994) n-hexane is preferred for oil extraction. (IUPAC, 1979) Mixture of polar and non-polar solvents has shown to extract all the lipids from most food. However, care should be given so as to prevent extraction of unwanted portion. The lipids extracted by this method without hydrolysis is suitable for further treatment to determine fatty acid fractions. (Greenfield Southgate, Review of methods of analysis, 2003) Alcohol-ether can be used to remove fat from tissue. Water-butanol is used in cereals. Chloroform-methanol is preferred for animal tissue (Pomeranz Meloan, 1994). Solvent extraction is the standard method of analysis for many types of food. Hence, it is widely used and is undergoing continuous improvement. There are different types of solvent extraction, each with its pros and cons. 3.1.1. Batch Extraction Batch extraction is a very simple, yet widely used method of extraction. The sample is mixed with one or more solvent which along with endogenous water (if any) forms multiple layer of varying concentration. As the lipids are more soluble in non-polar solvents than in water, lipid portion goes to the layer with more solvents and non-lipid component remains in the layer with more water. The lipid part is then separated using a separating funnel. The separation is based on partition principle hence multiple extraction of the aqueous phase is necessary to obtain most of the lipid. The weight of lipid not extracted is given by the equation below: (Pomeranz Meloan, 1994) -(ii) Where, is the weight of lipid remaining, the volume of aqueous layer, volume of solvent in each extraction step, the distribution ratio of lipid in solvent, the number of extraction steps. The selection of solvent is then done using the distribution ratio of lipids in known solvents. Folch method uses chloroform-methanol extraction followed by washing with water. This extracts all lipid from tissue except strandin which remains with the non-lipid phase. (Folch, 1957) Folch method was improved by Bligh and Dyer to improve the speed of extraction and purify the sample at the same time. (Bligh Dyer, 1959) Extraction using low toxicity solvents like hexane: propanol has also been developed. (Hara Radin, 1978) Batch extraction is usually slow and requires a large amount of solvent. When other faster and easier methods are available, this method is not preferred. However, as no sophisticated equipment is necessary, batch extraction is very useful where the cost of equipment outweighs the usefulness of more accurate data. 3.1.2. Continuous Extraction Continuous solvent extraction recycles the solvent used so that small amount of solvent can accomplish the equivalent extraction of several steps. This process is preferred for solid samples and sample where the distribution ratio is low. These samples need multi step extraction as very little lipid is extracted to the solvent in each step. (Pomeranz Meloan, 1994) Soxhlet extractor is widely used extractor for lipid. Although first developed to measure milk fat it has developed as a standard extractor for lipid as well as other substances. (Soxhlet, 1879) It has gone various improvements since its first publication and now various modifications are commercially available. Goldfish extraction is a faster extraction system which suspends the sample in the solvent vapour. Although faster than Soxhlet based system, it might not completely extract the lipid due to channeling i.e. solvent may take a preferential path in the solid sample and may not cover whole of the sample. (Moreau, 2005) As continuous extraction is faster and uses less solvents than batch extraction it is the most widely used extraction system. Moreover, the equipment used is not very expensive and can be used for extraction of other materials. However, these processes are slow and disposal of solvent is an everyday problem. 3.1.3. Pressurized Fluid Extraction Pressurized fluid extraction (PLE) is carried out in high pressure and high temperature. In literature, this process is also called Pressurized Solvent Extraction or Accelerated Solvent Extraction. The term ASE ®is the registered trademark of Dionex Corporation which manufactures pressurized fluid extraction apparatus commercially. (Dean, 2009) Richter et al. studied the effect of variables like temperature, pressure, solvent volume on extraction. Their work showed that the ASE ® extractor could provide results comparable to Soxhlet but with reduced extraction time and solvent volume. This is attributed to decreased viscosity of solvent, weaker bond between components and increased diffusion capacity of solvent at higher temperature. Increased pressure is primarily applied to keep the solvent liquid, however, it provides the added advantage of forcing the solvent into pores blocked by insoluble matter. (Richter, et al., 1996) However, there is evidence that PLE is not selective to lipids for certain foods. (Boselli, Velazco, Caboni, Lercker, 2001) Moreover, no significant difference was seen on lipid extracted from poultry meat between Folch, Soxlet or ASE ® method. (Toschi, Bendini, Ricci, Lercker, 2003) Pressurized solvent extraction can be highly useful in labs where routine extraction is required as it greatly reduces the extraction time and solvent use. On the other hand, the investment on the apparatus may not be economical if extraction is not carried out regularly. In all cases the stability of temperature sensitive components should be known before using PLE. 3.1.4. Supercritical Fluid Extraction Substance in temperature above its critical temperature and pressure is called supercritical fluid. (IUPAC, 1997) Solvent property of supercritical fluid was first demonstrated in 1879. (Hannay Hogarth, 1879) They have huge prospects in extraction because they combine the solubility power of liquid with penetration power of gas. Moreover, their solubility can be fine-tuned by changing the pressure and temperature. Carbon dioxide and water are the most promising fluid for supercritical extraction due to their non-toxicity and environmentally friendly nature. (Hedrick, Mulcahey, Taylor, 1992) 3.2. Non-Solvent Liquid Extraction In this method, the sample is treated with some liquid reagent which separates the lipid from sample and the lipid fraction is then measured. This method is mostly used to determine milk fat. They require specialized vessels for each method and cannot determine phospholipids. (McClements, 2003) Several methods are present: 3.2.1. Babcock Method 3.2.2. Gerber Method 3.2.3. Detergent Method 3.3. Instrumental Methods Different instrumental methods have been developed to determine the total lipid content of the sample. They rely on some physical properties that vary systematically with lipid concentration. (McClements, 2003) Based on the property measured it is mainly of three types: 3.3.1. Measuring Bulk Properties Density: Density decreases as lipid content increases. This relation can be used to know the percentage of fat in a sample. (McClements, 2003) Electrical Conductivity: Conductivity decreases as lipid content increases. Thus, it can be used as fat concentration measure. (McClements, 2003) Ultrasonic Velocity: This is a fast and non-invasive method for fat content calculation. Amplitude and brightness analysis can be used to find the fat content and also distribution. (Abdul, N, Mohd, Abu, Z, 2013) Moreover, attenuation(absorption) of ultrasound is linearly proportional to the amount of fat in the body. (Dukhin, Goetz, Travers, 2013) 3.3.2. Measuring Absorption of Radiation UV-VIS: Fatty Acid absorb UV light proportional to its concentration. This method requires sample preparation to remove substances like proteins and hydrophobic peptides which interfere with the measurement. (Forcato, Carmine, Echeverria, Pecora, Kivatinitz, 2005) Because of the extraction and dilution needed the process can be time consuming and labor intensive. (McClements, 2003) IR: Near infrared (NIR) spectroscopy is mainly used to analyze fatty acid content in food. (Mossoba, Azizian, Kramer, 2012) Fat show strong absorbance at 5.74 mm which provides rapid and online fat composition measure. (McClements, 2003) The carbonyl absorption is the major reason for lipids NIR activity. This method requires intensive calibration with other approved methods hence is mainly used for routine analyses of large number of similar sample. (Greenfield Southgate, Review of methods of analysis, 2003) NMR: NMR is also a non-destructive and fast method of total fat analysis. Although it requires a calibration curve, it is better suited than IR or UV because it can be operated by non-experts and the calibration curve is long lasting. (Oxford Instuments Molecular Biotools, 2010) X-Ray: Fat absorbs less X-Ray than lean meat. Hence, by building a proper calibration curve, fat content in meat can be determined by X-Ray absorption (McClements, 2003) 3.3.3. Measuring Scattering of Radiation Light and Ultrasonic Scattering: Light as well as ultrasound waves are scattered by oil droplets present in emulsions. The linear relation between concentration of droplet and light scattering can be used to measure total fat, provided no other interfering molecules exist. (McClements, 2003) X-Ray: Fat molecules show a sharp X-Ray scattering peak at 1.1 nm-1 while a water rich tissue shows a peak at 1.6nm-1. Thus, varying amount of fat can give a scattering profile which can be used for fat content determination. (Elshemey, 2011) 3.4. Other Methods 3.4.1. Solid Phase Extraction 3.4.2. Microwave Assisted Extraction Total Lipid Concentration is a very simple data about food. As lipid contain diverse chemical species, in addition to total lipid, the type of lipid and their distribution also plays a major role to determine the purity, nutritional value, aesthetic look and taste. Hence, complete information about the type of lipids is necessary for scientist as well as legal bodies. (McClements, 2003) Sample preparation is the most important part in most method to analyses lipids. As the lipid is extracted, care should be given to prevent the change of one form of lipid to another. Hydrolysis should be rigorously prevented as it reduces triglycerides and increases free fatty acids. Extraction should cause as less oxidation as possible. (Greenfield Southgate, Review of methods of analysis, 2003) Extraction in chloroform, chloroform-methanol and hexane-isopropanol is preferred. Storage of sample in cold at -20oC is preferred. (AAFCO Lab Methods Services Committee, 2014) The various method present have their advantages and drawbacks and the preferable method depends on the type of food and the type of lipid to me examined, (Greenfield Southgate, Review of methods of analysis, 2003) 4.1. Chromatography It is a very powerful tool for lipid analysis. It can give compete profile of the lipid molecules in the given sample. Chromatography separates the different components of lipid in fractions, these are then subject to spectrometric analysis which gives the molecular identity as well as relative concentration. IR, NMR and Mass Spectrometry are most commonly used. (McClements, 2003) These methods, although very reliable and comprehensive are very expensive due to the instrumental and reagent cost and is only carried out where complete molecular identification is required. (Greenfield Southgate, Review of methods of analysis, 2003) Three types are used: TLC: Thin Layer Chromatography is used to find concentration of different lipid groups. The TLC plate is prepared with suitable adsorbent and kept in proper solvent. A drop of sample is placed on one end and let to flow. The plate after separation to different fractions is compared to standard plates to identify the lipids. The spots can be analyzed further by GC, MS, NMR. (McClements, 2003) After the advent of HPLC, TLC use has decreased considerably. However, after the availability of pre-coated plates, the use of TLC for instant result is still carried out when there are few samples only. It is cheaper than HPLC. However, care during experimentation is required. (Christie, Thin-Layer Chromatography of Lipids, 2011) This method cannot be used to separate different types of phospholipids. (Zaima, Goto-Inoue, Adachi, Mitsutoshi, 2011) HPLC: High Performance Liquid Chromatography is now a preferred method for lipid analysis. This is because it is more versatile than TLC and operates at room temperature, thus can be used to analyses labile groups that cannot be done using GC. (Christie, Thin-Layer Chromatography of Lipids, 2011) GC: Gas Chromatography is the preferred method for analysis of trans fatty acid. It can also be used for triglycerides and fatty acids; however, methylation is necessary. (Greenfield Southgate, Review of methods of analysis, 2003) Fatty acids are non-volatile, hence before carrying out GC, the lipids are saponified and methylated to give Fatty Acid Methyl Esters(FAME) which are volatile and can be used for GC. (McClements, 2003) -(2) It is now possible to convert a lipid sample of a fraction of a milligram in size to the methyl ester derivatives, separate these by gas chromatography, and have a quantitative result in under one hour. (Christie, Chapter 1 Introduction and Summary, 2011) 4.2. Chemical Methods These methods are very cheap and do not require expensive machinery. However, only crude and average results are obtained. Following test gives different information on fat: Iodine Value: It gives the average degree of unsaturation in the lipid. The lipid to be analyzed is titrated with ICl and the consumption of ICl gives the amount of unsaturation in lipid. Saponification Number: It gives the average molecular weight of triglycerols. The triglycerols are saponified with KOH and the amount of KOH used is determined. This is the saponification number. High saponification number corresponds to low molecular weight and vice versa. Acid Value: It gives the amount of free fatty acid. Here, the lipid is titrated with KOH until the solution turns alkaline. Other acids may interfere with results. (McClements, 2003) 4.3. Instrumental Techniques Various instrumental techniques for fat analysis are present. Methods like NMR, IR, MS are usually coupled with chromatography. Measurement of density and refractive index can be used to measure change in chain length and unsaturation. (McClements, 2003) Lipids with high unsaturation undergoes aerial oxidation. This includes variety of reactions usually summarized as follows: reactants à ¯Ã‚ ¿Ã‚ ½ primary products à ¯Ã‚ ¿Ã‚ ½ secondary products (unsaturated lipids and O2) à ¯Ã‚ ¿Ã‚ ½ (peroxides and conjugated dienes) à ¯Ã‚ ¿Ã‚ ½ (ketones, aldehydes, alcohols, hydrocarbons) 5.1. Chromatography Loss of reactants as well as formation of specific products can be monitored by using time profile. 5.2. Oxygen Uptake Measures the amount of oxygen consumed over time while maintaining constant oxygen concentration on the reaction vessel. 5.3. Peroxide Value Measures the amount of peroxide formed by titration with iodine. 5.4. Conjugated Dienes Measures the concentration of conjugated dienes by UV spectroscopy (at 233nm for diene and 268nm for trines) 5.5. Thiobarbituric Acid(TBA) Measures the secondary products (aldehydes) in the sample. The sample is treated with TBA and absorbance measured at 540nm. The absorbance value corresponds with the concentration of aldehyde. 5.6. Accelerated Oxidation Tests The sample is oxidized in oxidation friendly environment and the time taken for rancidity to form is measured. These tests help to know the physicochemical characteristics corresponding to flavor, appearance, flow etc. 6.1. Solid Fat Content(SFC) Measures the fraction of fat present as solid. Density measure is mostly used (3) Where is the density at given temperature and are the density if it was completely liquid or solid at the same temperature. NMR signal decay rate is also being used recently. More solid component, faster is the signal decay. Differential Scanning Calorimetry uses latent heat measure are also used to measure SFC-temperature profile. 6.2. Melting Point Used when SFC is not required but only the temperature of melting is required. Due to different components present no sharp melting point is seen. Instead different melting points are used: Clear Point: The temperature at which fat completely melts and becomes clear Slip point: The temperature at which the fat in a capillary tube starts to slip. Wiley melting point: the temperature at which a disc suspended in alcohol-water mixture turns to a sphere. 6.3. Cloud Point The temperature at which a completely melted lipid starts to develop turbidity. 6.4. Smoke Point The temperature at which the lipid starts to smoke at standard condition 6.5. Flash Point The temperature at which a flash appears on the surface at ignition at standard condition 6.6. Fire Point The temperature at which a continuous flame stats to form at standard condition 6.7. Rheology The measure of deformation and flow. Viscosity, elastic modulus and other relevant flow or plasticity measure is used. (n.d.).
