Shakespeare and Anti-Semitism in the Merchant of Venice

Anti-Semitism and the desecration of the Jewish population have been in existence for nearly five thousand years. In the Elizabethan era, a question of anti-Semitism invariably arises. In William Shakespeares The Merchant of Venice, we find that one of the characters is the embodiment and expression of anti-Semitic attitude that is pervasive in Elizabethan society. Anti-Semitism was an intricate part in Shakespeares years. Jews were considered vile and scorned upon. Shakespeare presents Judaism as an unchangeable trait (Bloom 37). Shakespeares age based their anti-Semitism on religious grounds because the Elizabethans inherited the fiction, fabricated by the early Church, that the Jews murdered Christ and were therefore in†¦show more content†¦In act two, scene two, lines twenty-four through twenty-eight, Launcelot Gobbo identifies Shylock as a kind of devil, the devil himself, and the very devil incarnation. Shylocks daughter, Jessica, identifies Shylocks house as h ell. Solanio identifies Shylock as the devil . . . in the likeness of a Jew (III,i,19-21) and Bassanio echoes this sentiment by identifying Shylock as a cruel devil (IV,i,217). Antonio further cements the association between Shylock and the devil by noting how Shylocks arguments remind him how The devil can cite scripture for his purpose (I,iii,97-100). This explicit demeaning of Shylock cannot but be significant in light of the historical outline that has been observed through the desecration of Jews for many years. The images of Jews as blood-thirsty murderers of Jesus who snatch innocent Christian children for slaughter in bizarre Passover rituals seems to provide a potent back-drop for the demonic appellations that are heaped upon Shylock in The Merchant of Venice (Fiedler 63). The progressive abuse of Shylock as a usurer, which leads to the reduction of his humanity to a demonic form, should fully prepares us for the revelation in The Merchant of Venice that Shylocks motive for the entire bond with Antonio is murder. By murdering Antonio, Shylock will be rid of a bothersome business of rival. The play appears to suggest that Bassanio was right to caution Antonio to suspect fair termsShow MoreRelated Is The Merchant of Venice an Anti-Semitic Play?

Master At Greenville Technical College - 947 Words

Young 1 When I finish my associates in Arts at Greenville Technical College, I plan to transfer to get my Bachelors (B.A.) in Early Childhood Education from University of South Carolina- Columbia. I chose this career because I love children with a passion and every job I’ve had has been with children involved. Being in the presence of children makes me happy. I also chose this career because I know that when I wake up in the morning I will not dread going to work every day, I will gladly get up an strive to make a difference in their lives. I want to be an impact on as many of their lives as I can by being a part of their life and teaching them. I want to be someone they look up to, someone â€Å"who inspires and encourages us [them] to strive for greatness, live to our [their] full potential and see the best in [them]† (Teach). To become a teacher takes a lot of hard work and motivation. Education itself has come a long way. In the earlier times, certain races and genders were not able to learn, blacks and whites were not able to sit in the same classrooms, or use the same things, and many people just couldn’t get along. Today, every gender and race is entitled to make something of themselves and get an education, we all have the right to learn.

Short Notes Free Essays

â€Å"Two gentlemen of Verona† â€Å"An Irish Rose† are the two heart touching stories written by A. J. Cronin. We will write a custom essay sample on Short Notes or any similar topic only for you Order Now In an Irish Rose, the 14 year old Rose plays the central character of the story. She sacrifices her life to look after her baby brother who lost his mother when he was just one month old. In the â€Å"Two gentlemen of Verona † we find the touching story of Jacopo Nicola ,two brothers aged 12 13 who do odd jobs and live a hard life themselves to sustain and treat their elder sister Lucia who is suffering from tuberculosis of spine. Both stories of A J Cronin are heart touching. In an analysis of the characters portrayed in both the works we can find certain similarities. As stated above we can see the characters themselves in a moral and sacrificial light wherein they are not thinking or living for themselves but for their respective siblings. If we go into the actual character portrayal too, we can find how the characters are dressed in rags to save even the smallest penny for their siblings comfort. They do not even eat or dress well lest they have to spend any money, which can be found to have a better use for their siblings. In the Irish Rose as well as the Two Gentlemen of Verona, we find that the author finds hope for a better future of the world after meeting Rose, Jacopo and Nicolo. Never thinking for themselves, all three of his characters have fought to better the lives of their loved ones in every way possible. In both the stories the plot is set in a rousing manner and giving a detailed and graphic expression till the climax. In the Irish Rose, the main character Rose Donegan has to earn for the family, buy milk for her youngest brother Michel. She had to cook, attend to the children and father. With a slum child’s elemental knowledge she had to do everything, even she would bargain the baker to extend her credit for an extra loaf. As in the case of the Two Gentlemen OF Verona, the writer himself becomes a character in the plot of Irish Rose. Along with the writer the rest of the characters too play a significant role in the plot to finally bring out the actual sacrifice of the three children. In both the stories the importance given to the children’s attitude towards work, love and responsibility shows how important the said characters are in the view of the author too. Herein we find the hope for a better world when these children grow up rather than the war ravaged time frame in which the stories are set. It was W. B. Yeats who said that, â€Å"Too long a sacrifice can make a stone of the heart†. But through these stories Cronin has endeavored to prove Yeats wrong, as nicely as possible. He was also able to teach us the value of not running away from our responsibilities. How to cite Short Notes, Essay examples

Leonardo Da Vinci modern review Essay Example For Students

Leonardo Da Vinci modern review Essay You are about to read a story of Leonardo Da Vinci. We hasten to tell you we have another variant Leonardos biography. Leonardo Da Vinci (Born 1452. Died 1519) The fourth centenary of Leonardo da Vinci has been celebrated in Italy; in England the date of the death of this strange and legendary figure of the latter half of the fifteenth century, who was still climbing after knowledge infinite,† has passed almost unnoticed. Always one of the world’s greatest names—for no artist of the past lent himself so readily to apotheosis — his fame has grown with the revelation of his greatness as a man of science. Other sons of the Renaissance, such as Leon Battista Alberti, were gifted with comprehensive genius, but the quality of Leonardo’s endowment dwarfs their record when we sum up his activities as painter, sculptor, architect, engineer, hydraulician, anatomist, mathematician, geologist, botanist, astronomer, and geographer. Apart from his guesses and achievements in these provinces, there is something in his personal character â€Å"super-European and silent,† as Nietzsche terms it, â€Å"the character- istic of one who has seen too wide a circle of things good and evil.† He behaved in such a way as to arouse the wonder of his contemporaries. â€Å"He dressed with originality and distinction, bore himself impressively. Sur- rounded, so to speak, by censer-swinging acolytes, he acted the part of hierophant and modern Empedocles, and was not far from being a precursor of Paracelsus.† He was  unconditioned, above the law, the divine artist, the worker of miracles. Yet he was a solitary in the midst of court life, in the changes and chances of his employment, and speaks of the necessity of the solitary life in no uncertain voice: â€Å"If you are alone, you belong entirely to yourself; if you are accompanied even by one companion, you belong only half to yourself, or even less in proportion to the thoughtlessness of his conduct; and if you have more than one companion, vou will fall more deeply into the same plight.†* We see how the strange and solitary power is impressed on his red chalk drawing in his old age of his silent face. The index of a mind forever Voyaging through strange seas of thought alone.† For all his cryptic utterances and the reserve of his spirit, we must not suppose that he was in any respect a charlatan, a suspicion that clings to the name of Para- celsus. His notebooks bear witness to the intense and laborious concentration of his mind upon the problems of science, physics, or engineering he had set before himself, to his patient and manifold industry, the ordered continuity and range of his effort. His personal character, as shown in the glass of his notebooks rather than in the distorting mirror of Vasari’s famous Life, reveals an authentic greatness. â€Å"I wish,† he says, â€Å"to work miracles; I may have fewer possessions than other men who are more tranquil and those who wish to grow rich in a day.† â€Å"As a well-spent day brings happy sleep, so life well used brings happy death.† â€Å"Our body is subject to heaven, and heaven is subject to the spirit.† â€Å"Where there is most power of feeling, there of mar- tyrs is the greatest martyr.† â€Å"Intellectual passion drives out sensuality.† â€Å"To the ambitious, whom neither the boon of life nor the beauty of the world suffices to content, it comes as a penance that life with them is squandered, and that they possess neither the benefits nor the beauty of the world.† These sublimations of Leonardo’s experience are expressed with a concision which renders him, like Blake, the master of significant language. Leonardo’s life is a paradox. He recommends for the artist a life spent in the seclusion of the studio; his own was spent in courts; a wanderer, from place to place Florence, Milan, Rome, finally Amboise in France. The most laborious of men, he has left little realized and achieved work in building and the arts behind him. None of his monumental projects of construction or town-planning seem to have been carried out, most of his paintings and sculptures were never executed, others were left half finished. He has survived his masterpieces. Modern research has shown him to have been, not the capricious and inconstant artist whose performance was always less than his promise, but the most learned of painters, studying with the intentness of a scientist the medium in which he worked, the structure of the human body, plants, trees, and rocks, in order that he should know their essence and inner reality. His habit of scientific investigation* in the end drew him aside from the practice of his art; he was rapt away by the Virgilian passion rerum cognoscere causas. It was impossible, Isabella d’Este found, to get a picture out of him. She had applied to a friar of the Carmelite Order whom she knew, to know what manner of life the master was leading, and the answer was returned that he was â€Å"entirely wrapped up in geometry, and has no patience for painting.† The whole world of knowledge was his province. In reading his notebooks there is at first a feeling of dis- appointment at the meagerness of the scientific result, but this is counterbalanced by the realization that he is the first of the moderns in his belief in experimental methods, his distrust for mere authority in science as in the arts he practised. â€Å"Whoever in discussion,† he writes, â€Å"adduces authority, uses not intellect, but rather memory.†4 He has been loosely said to have been the forerunner of Bacon, Watt, Newton and Harvey, but it cannot be maintained that he anticipated their discoveries in any definite sense. Though he set down in unusually large letters â€Å"the sun does not move,†9 and surmised that the earth was a star â€Å"much like the moon,† and knew that blood moved,* and so forth, his actual achievements were in the invention of certain ingenious devices, such as the diving-bell and the lifebelt, and in the employment of a definitely scientific method, as in his discovery of the significance of fossils found in the mountain ridges of Lombardy as showing the waters at one time covered the earth. â€Å"If you should say that the shells which are visible at the present time within the borders of Italy, far away from the sea at great heights, are due to the Flood having de- posited them there, I reply that, granting this Flood to have risen seven cubits above the highest mountain. those shells which always inhabit near the shores of the sea   ought to be found lying on the mountain side, and not at so short a distance above their bases, and all at the same level, layer upon layer. Should you say that the nature of these shells is to keep near the edge of the sea, and that as the sea rose in height the shells left their former place and followed the rising waters to their highest level: —to this I reply that the cockle is incapable of more rapid movement than a snail out of water, or is even somewhat slower, since it does not swim, but makes a furrow in the sand, and supporting itself by means of the sides of this furrow it will travel between three and four braccia a day; and therefore with such a motion as this it could not have traveled from the Adriatic Sea as far as Monferrato in Lombardy, a distance of two hundred and fifty miles, in forty days. Art History: The Movement II: People EssayHe sings hymns to Law and Causation: â€Å"Nature never breaks her own law. â€Å"O marvelous necessity, thou with supreme reason constrainest all efforts to be the direct result of their causes, and by a supreme and irrevocable law every natural action obeys thee by the shortest possible process. â€Å"Who would believe that so small a space could contain the images of all the universe? O mighty process, what talent can avail to penetrate a nature such as thine? What tongue will it be that can unfold so great a wonder? Verily none. This it is that guides the human discourse to the considering of divine things.† Leonardo, who sums up war as a â€Å"bestial frenzy† (in   the descriptive passage entitled â€Å"The Way to Represent a Battle†), was the inventor of numerous engines of war, steam guns and breech-loading arms with screw breech block, and in the draft of a letter in which he offers his services as architect and military engineer to Ludovico Sforza, Duke of Milan, he claims that he can â€Å"construct bridges that arc very light and strong and very portable, with which to pursue and defeat the enemy, and others more solid, which resist fire or assault,† also â€Å"a kind of cannon which is light and easy of transport, with which to hurl small stones like hail,† â€Å"catapults, mangonels, tra- bocchi, and other instruments of admirable efficacy not in general use,† and â€Å"armored wagons carrying artillery which shall break through the most serried ranks of the enemy, and so open a safe passage for the infantry†he can also construct †Å"subterranean passages either straight or winding, passing if necessary underneath trenches or a river. † As far as the evidence of Leonardo’s manuscripts can substantiate the claims put forward, they have been found to have been correct; and Dr. Mà ¼ller-Walde,18 in that por- tion of his work dealing with Leonardo as a military en- gineer, has shown that Leonardo did in fact study the construction and use of the engines of warfare mentioned in the first seven clauses of the letter. In the arts of peace, his schemes and sketches for canalization and the layout of towns are no less remarkable. According to specialists’ opinions, Benedetto Castelli, who is considered to be the actual originator of the Lombardy canal system, appears to have studied Leonardo’s schemes, in which practical standards for hydraulic engineering are already worked out. He wished to lay out cleaner and healthier cities, so that the people would not need to live â€Å"packed together like goats, and pollute the air for one another,† and proposed to II Moro to build ten cities, each with 5000 houses and accomodating 30,000 inhabitants. These cities are to be seated on rivers regulated by locks; the streets are to be as wide as the height of the houses, and laid out with wide squares and market-places. Moreover, he provides two kinds of streets on different levels, the higher and spotless walks for foot passengers, and the lower for traffic, which can be cleaned by flushi ng from locked rivers.*8 In his notebooks are found a wealth of designs, exhausting every possible combination of circular and polygonal ground-plans for domed public buildings and churches. As he himself states, it was his intention to write a treatise on the theory of cupola construction. His devices and designs for hydraulic work, and for warlike machines, were, for the most part, within the limits of possible construction in his day. It is otherwise with the problem that occupied so much of his time, that of flight. He had for many years watched the flight of birds, and made himself, thanks to an amazingly keen power of fixing rapid movement, familiar with every characteristic of wing action. The subject gives its name to a treatise which exists in a more or less complete form—II Codice sul volo degli uccelli. and is also treated in the Codice Atlantico and other of Leonardo’s manuscripts. The conviction grew on him that men might raise themselves above the earth on wings, for: â€Å"A bird is an instrument working according to mathematical law, which instrument it is within the capacity of man to reproduce, with all its movements, but not with a corresponding degree of strength, though it is deficient only in the power of maintaining equilibrium. We may there- fore say that such an instrument constructed by man is lacking in nothing except the life of the bird, and this life must needs be supplied from that of man.† Flight is a natural phenomenon, and consequently its laws are to be deduced by observation of nature. Yet Leonardo doubted the adequacy of strength of the human agent to accomplish more than short flights, and sought to supplement it by a screw-propeller. He has a drawing of a large screw constructed to revolve round a vertical axis. â€Å"The notes at the side and below the drawing tell of the materials and dimensions, and reveal also the purpose which it was intended to serve. M. Govi, who first called attention to the significance of these passages, speaks of them as proving not only that Leonardo invented the screw-propeller, but that he had considered small paper models for this purpose, which were set in motion by fine bent steel wires.† He must have, at one moment, at any rate, felt sure of success, when he wrote triumphantly that â€Å"the huge bird will take his first flight high aloft on the ridge of his great Ceceri—the mountain between Majano and Fiesole—he will fill the universe with wonder and all writings with his fame.† The experimental flight must have failed, but from his own day Leonardo has not been judged by his achievement, for, in the words of his earliest biographer, â€Å"his spirit was never at rest, his mind was ever devising new things.†

Caroline Herschel (Astronomer and Mathematician)

Caroline Herschel (Astronomer and Mathematician) Dates: March 16, 1750 - January 9, 1848 Known for: first woman to discover a comet; helping discover the planet UranusOccupation: Mathematician, astronomerAlso known as: Caroline Lucretia Herschel Background, Family: Father: Isaac Herschel, court musician and amateur astronomerSiblings included: William Herschel, musician and astronomer Education: educated at home in Germany; studied music in England; taught mathematics and astronomy by her brother, William About Caroline Herschel: Born in Hanover, Germany, Caroline Herschel gave up on getting married after a bout with typhus left her growth stunted seriously. She was well-educated beyond traditional womens work, and trained as a singer, but she choose to move to England to join her brother, William Herschel, then an orchestra leader with a hobby in astronomy. In England Caroline Herschel began assisting William with his astronomical work, while she trained to become a professional singer, and began to appear as a soloist. She also learned mathematics from William, and began helping him with his astronomy work, including grinding and polishing mirrors, and copying his records. Her brother William discovered the planet Uranus, and credited Caroline for her help in this discovery. After this discovery, King George III appointed William as court astronomer, with a paid stipend. Caroline Herschel abandoned her singing career for astronomy. She helped her brother with calculations and paperwork, and also made her own observations. Caroline Herschel discovered new nebulae in 1783: Andromeda and Cetus and later that year, 14 more nebulae. With a new telescope, a gift from her brother, she then discovered a comet, making her the first woman known to have done so. She went on to discover seven more comets. King George III heard of her discoveries and added a stipend of 50 pounds annually, paid to Caroline. She thus became the first woman in England with a paid government appointment. William married in 1788, and though Caroline at first was skeptical of having a place in the new home, she and her sister-in-law became friends, and Caroline had more time for astronomy with another woman in the house to do the domestic chores. She later published her own work cataloguing stars and nebulae. She indexed and organized a catalogue by John Flamsteed, and she worked with John Herschel, Williams son, to publish a catalog of nebulae. After Willliams death in 1822, Caroline had to return to Germany, where she continued writing. She was recognized for her contributions by the King of Prussia when she was 96, and Caroline Herschel died at 97. Caroline Herschel was, along with Mary Somerville, appointed to honorary membership in the Royal Society in 1835, the first women to be so honored.

Buddhism Essay Example | Topics and Well Written Essays - 1000 words

Buddhism - Essay Example Buddhism is one such religion. It is a religious practice that recognize and appreciates the reasonable teaching that emanate from every other religion (Harvey 19). Moreover, it tolerates the customs of other religions and cultural practices that might not be able to appreciate their teaching of Buddhists in return. Buddhism In essence, Buddhists are in a position to respect the views of man and appreciate other practices without harboring any religious prejudices. Buddhists, who are not able to appreciate the ways of other religious practices, maintain their silence and refrain from confrontations of any kind thus ensuring that is peaceful co-existence through sympathetic understanding (Harvey 23). Buddhism commenced as a reform group in Hinduism; India in the sixth century B.C (Eliot, 20). It was one of the ancient religions to emerge to become international having a membership of over two hundred thousand people. It was founded by Siddhartha Gautama, who was a son of the ruler of the Kshatriya caste (Eliot, 22). Gautama left his family and went out to seek enlightenment concerning the sufferings and anxiety of a decrepit man that he had witnessed in outside the royal compound. After seven weeks, he received the Enlightenment, hence became Buddha-the enlightened one. The Buddhists emphasize on practicing a religion that is honest, sincere, and truthful and that which is kind to others. They do not try to justify war under any circumstances rather they believe in solving a problem in a more considerable way while ensuring that they are not irritated or angered by people not paying attention to them (Skilton 24). In fact, they argue that, the attitude of a real religion; the Buddhism is to advice people instead of ruling or intimidating them. According to Buddha, human beings are not cruel or wicked by nature rather they make mistakes and act as cruel as people due to their ignorance. Hence the importance of guiding them in the right path, as opposed to condemn ing them to external suffering or religious damnation. They point out the vainness of certain religious beliefs and practices but at the same time preach religious intolerance. Needles to say, Buddhism has also been able to incorporate religious practices and customs from other religions, which have refined them in the course of their expansion (Skilton 26). Buddhism as a reform religion In relation to this, I agree to the fact that Buddhism is a reform religion. This is because Buddha who was associated with the Buddhism, lived a life that was sustainably different he considered himself as one who revolutionized the religious way of life in a more dignified manner. Although he was condemned, criticized and insulted by most noted teachers and critics, there is no doubt that Buddha reformed certain customs, duties pertaining to religion, rites, ethics and the general way of life. Essentially, his outstanding character cut across the buckets of false beliefs and practices that were pr esent in the religion leading to the exposure of the fact that they lacked content (Harvey 27). In particular, he brought up the idea of Nibbana, the Eightfold Path and the Four Noble Truths. And even though they believes were common per say, he gave rational and realistic explanations to support his argument and initiated it as a natural law of cause and effect. Further more, he appreciated the value of the many he come across especially those that related to the Truth hand even offered an explanation of their

Bacons Rebellion Essay Example | Topics and Well Written Essays - 750 words

Bacons Rebellion - Essay Example This reality struck the manipulative white class which controlled the disadvantaged class. As is shown in the picture below, whites and blacks are together preoccupied by a mission, however offensive it may be. The picture shows white Virginia settlers and amidst them there are also black men. The man on extreme right beating the drum is a black rebel who like other men in the picture is provoked by Bacon to set Jamestown on fire. The supporters Bacon gathered around himself to thwart Berkeley for personal reasons were a mix of whites and blacks. The image above also shows that Bacon, though leading the rebellion for personal motives, unconsciously demonstrated to the ruling white class that poor whites and blacks could be unified for a solid cause. The whites and blacks who would never stand close to one another struck up an alliance which sent out a very clear message to the rich Virginia colonists. There is a message of unity emanating from this picture and this message frightened the rich white class. This unity between poor white and black social groups motivated the ruling elites to turn whites against black servants by inculcating a sense of racial hatred in them. This also motivated them to incapacitate poor blacks by the aid of slavery. It was due to this alliance between whites and blacks in the Bacon’s rebellion that the rich white planters set out on creating distances between them by very strategically extending more benefits to the disadvantaged whites. Giant masses of Negro slaves and white servants bonded during the course of Bacon’s rebellion. They allied against rich whites of Virginia because Bacon promised them equal rights and independence from economic contraction. It is not a general consensus that Bacon only instigated this rebellion for personal benefits (Rothbard 2012). Bacon might have had some good reasons too to start a rebellion on such a large scale as was believed by a large number of whites and

ESSAY PROMPT Example | Topics and Well Written Essays - 1250 words

PROMPT - Essay Example If we talk about Hamlet, we can’t but mention that suicide represents a continuous theme in the tragedy. During the play Hamlet considers suicide many times, his thinking about the life and its essence, about the troubles of real life and the fascination of unconsciousness is famous all over the world as remains unique. The given paper will discuss two famous soliloquies of Hamlet, in which he is talking about death and prove that Hamlet does not really want and was going to die. Hamlet is naive and passionate, not suicidal. Evidence: Soliloquy in Act I When we get acquainted with Hamlet, his first soliloquy in Act I reveals his nature. We see a passionate and vulnerable guy who is extremely astounded by his father’s death. He is almost a child and can’t help crying and wishing to die to be with his beloved father. It is very difficult to lose parents, especially when you are still young. Moreover, Hamlet has one more reason to be so upset: his beloved mother doe s not share his sorrow. Instead she is celebrating her wedding with Hamlet’s uncle Claudius. A young person, who still considers love to be a sacred thing is shocked with such an indifference. The pain is stronger because he knows what love is himself – and we remember about Hamlet’s feeling to Ophelia. Hamlet knows what love is, thus he is extremely astounded by the events as he considered his father’s marriage to be happy. ... The father is dead and the mother is married to another man, thus she does not share the son’s sorrow about the death of his father. These thoughts of suicide are not true, they are the results of the young guy’s despair. Hamlet’s soul is beautiful and he was sure that the souls of other people, especially his own mother’s soul was also pure and beautiful. But now he calls his mother: â€Å"an unweeded garden that grows to seed.† (1.2.139). He considered his mother to be sacred but suddenly became a witness of her fall. He is full of negative emotions, thus he thinks about death like many other people in such state. Hamlet is also religious. He perfectly understands that death is a sin, thus he should not even think about it. He feels bad but would never commit suicide at that moment as he believes in â€Å"Everlasting† (1.2.135). In the Act 1 Hamlet still believes that the God would save him and would not let him die. Here we see Hamlet as s till young, naive and sentimental creature who cries about the love between his parents, which he considered to be true, but now he has to change his mind because of the mother’s very fast marriage. Having high moral principles and believing in God, Hamlet suffers recollecting his mother’s â€Å"unrighteous tears† (1.2.159) caused by the father’s death, the tears, which he considered to be true. â€Å"To be or not to be† does not mean â€Å"to live or not to live†. Evidence: Soliloquy in Act III In the Act 3 we already see Hamlet from another side and this makes us understand that everything he said and was thinking about in Act 1 was just childish melancholy. Hamlet also understands this and this is what his most famous soliloquy is focused on. After his conversation with the ghost he suddenly

Factors Contributing to Obesity and Diabetes among Americans

Factors Contributing to Obesity and Diabetes among Americans Obesity is a condition that emanates from malnutrition and presents with serious social and psychological problems. It is present across different ages and affects individuals in the developing and developed countries. Aiko and Sturm (845-856) writes that obesity has turned into one of the most serious global epidemics as it spreads, to many parts of the globe affecting millions of healthy lives each day. The most shocking revelation is that obesity epidemic is not only affecting developed nations. From studies this condition continues to affect even the individuals in the developing world. This essay aims at discussing some of the views of Aiko and Sturm who authored an article dubbed â€Å"The obesity epidemic and changes in self-report biases in BMI.† on obesity epidemic and how self-report biases have increased the trends in obesity cases across the globe. This essay will also cite the research gaps that the authors did not include in their study. According to World Health Organisation (WHO), the obesity epidemic remains one of the ignored public health problems that affect millions of individuals across the globe. In a forecast, WHO predicts that without proper public health initiatives, obesity epidemic will affect many people globally and lead to aggressive health complications. According to WHO, this condition is mainly affecting women as compared to men. Nonetheless, the author notes that many men have higher cases of overweight while women have higher cases of obesity. What the article fails to mention is the cases of obesity among children. Children who had developed obesity in the US and other major cities tend to place the blame on the food sellers such as McDonald. The author reiterates that while many people blame the eater (children), the blame should be made on the food makers. I agree with the author on the fact that many children who are trying to get affordable foods often end up feeding on unhealthy fast foods. Such foods as stated by Aiko and Sturm (855) should not be taken more than once in a single day. However, the author notes how he had to eat fast foods repeatedly since it was the only option for affordable food. This article explains that there are many cases of diabetes because the fast food industry has grown ten-fold t offer children as well as adults cheaper and easier alternative to affordable foods. Nevertheless, many people working in the restaurants have not realised the dangers that they expose their customers to. I also agree with the fact that ignorance among individuals has contributed to obesity epidemic. While many people yearn for sumptuous foods sold in McDonald, Taco, and KFC, a few understand the risks of obesity that they are exposed to. The fact that Food and Drug Administration does not cover prepared foods, there is little information concerning the caloric contents of such foods. Additionally, I also contend with the claim that marketing of hazardous fast foods to children is to blame for the heightened rates of obesity among the children. As many fast food companies continue to grow, many children find access to such foods regularly. This has led to unprecedented levels of risks of developing obesity. In this manner, the claim by the author that food sellers are to be blamed for the obesity epidemic. However, the author did not mention the possible effects of sedentary lifestyle and other risk factors such as family history of obesity and lack of warning labels on high-calorie foods. On the other hand, there are many initiatives that had been introduced in the US such as funding for new bike trails and sidewalks, restrictive labelling of foods and prohibiting marketing of dangerous foods to children. According to the article, such initiatives have the ability of reducing the cases of obesity among school children. High tax for high-fat foods aimed at reducing the production and sale of foods known to cause obesity among the children. According to Gotay et al. (e64-e68), such initiatives are wrought and irrelevant. Balko (Para.3) objects such moves on the basis that they limit the ownership of one’s control of health. The author says that if such regulations are enforced, then certain individuals are forced to be responsible for other people’s problems. I contend with the claim that individuals have become irresponsible for their own health. While people are supposed to care about their health, many individuals continue to blame the Federal Government on healthcare management. While many consumers continue to develop bad habits, obesity epidemic continues to rise. I also contend that whatever we eat is our own business. While there are many people who think that public health can resolve the issue of obesity, I concur with the writer that our health is a private issue and should not belong to the public health. For instance, Aiko and Sturm (856-860) note that fighting the obesity epidemic starts by change of lifestyle, nutrition as well as physical exercise. These preventive measures are often done privately and not with the help of the government or the public health. However, I disagree with the author on account that healthcare should be privatized. While the government spends millions of shillings in facilitating preventive proj ects, Dietz (575-596) acknowledge that many people may not be able to afford such initiatives. The cost of health is very high, as such; public health programs aim at initiating preventive measures that target the reduction of diseases and epidemics. It is true that the contemporary methods of measuring obesity among various populations. The article dubbed, â€Å"The Obesity Epidemics and the changes in the Self-reported biases in BMI,† gives a clear insight of how cases of obesity are not fully discovered among individuals. Idyllically, such cases may remain obscure for a longer period of time without the knowledge of the public health officials. I agree with the author that biases subject to social desirability as well as recall errors have led to poor reporting of obesity cases in many countries. As such, this event has facilitated increased cases of obesity leading to unimaginable obesity epidemic. The author notes that BMI measurement error leads to underestimation of the BMI that can be used to determine the case of obesity among individuals. I also contend with Aiko and Sturm on the fact that media coverage on the cases of obesity has uncovered the lack of awareness among individuals and their weights. According to Aiko and Sturm (4), poor reporting of BMI is one of the faults that ostensibly cause lack of awareness on obesity and related disorders. However, the media has played an imminent role that has transformed lives of many individuals by exposing the disparities in BMI self-reports and the actual BMI reports. While the bias in self-reporting has been cited as one of the reasons why obesity is growing rapidly in the US, Aiko and Sturm (3) note that measuring of the BMI should include the detailed analyses that will minimise the errors that occur during measurement of the procedures. While the media has been proactive in raising obesity awareness in the recent times, Aiko and Sturm (5) note that the problem of error in self-reporting has led to poor accuracy in estimating the number of individuals who suffer from obesity. To this end, acknowledge that there are possibilities of the obesity epidemic becoming out of control. Individuals only continue to gain weight when there are no weight reduction initiatives. As such, it is important to institute proper weight and height measuring techniques that ensure accuracy in reporting the BMIs of individuals. The BMI measurement remains the commonest way of determining whether an individual is obese or not. In this manner, it is imperative as stated by Aiko and Sturm (5) to use techniques that teach individual populations on the obesity epidemic. On the contrary, I disagree with the claims of the author that the outburst of obesity epidemic is due to errors in measuring the BMI among individuals. Ideally, there are many factors that have changed over time concerning how individuals view healthy choices. Awareness on the obesity issues help in adopting preventive measures that help many individuals in preventing obesity. In this manner, the author should have included lack of information as one of the main facilitators of obesity. A mixture of factors leads to the development of obesity. In this manner, note that erroneous measurement of the BMI can only be counted as a secondary factor in the development of obesity epidemic. The American Heart Association indicates that many Americans are dealing with complications of obesity in the United States. This is a confirmation that this condition has become a major epidemic. Individuals have chosen unhealthy lifestyles that continue to facilitate the development of the epidemic. With the increased trends in technology, sedentary lifestyles have replaced the manual techniques that ensured physical activities among individuals. On the other side, resisting food cues has been a major problem among many individuals suffering from weight problems. As such, there is a major problem in dealing with nutrition and lifestyle than dealing with BMI measurement errors. However, Aiko and Sturm (4) are also right since raising awareness on obesity can help people in remaining fully aware and capable of regulating risks that can initiate the development of obesity. To this end, it is evident that obesity epidemic is dependent on variant factors that should be considered while preventing the condition. Works Cited Dietz, William.

Integration and Animal Farm by Orwell :: Free Essay Writer

Integration and Animal Farm by Orwell Integration of Education in the United States Throughout history, education is recognized as one of the key components of any civilized society. It is a natural instinct for man to learn, and feel the need to pass on that knowledge to their young and to all those who come behind them. People have a passion for education, and will fight for the opportunity to gain the valuable knowledge that education provides. The importance of education in a society is illustrated in two aspects. The first being the actual events in American history regarding the desegregation of schools, and the second being the action of the animals in George Orwell's Animal Farm upon receiving their liberation on Manor Farm. In recent times we have witnessed a struggle in American society for the opportunity of minorities to realize the education that their white counterparts received. It began with slavery, when blacks were prohibited from obtaining even the basic skills to read and write. When blacks were finally allowed this liberty, we began our own makeshift schools, and were content with this opportunity. As time progressed, and more formal schools were established, minorities realized that they were not receiving the same quality education as those of the majority. This sparked a legal battle that lasted over fifty years. The first landmark was the case of Plessy v. Ferguson in 1896. It established the doctrine of "separate but equal." This concept stated that separate public facilities of equal quality do not violate the equal protection clause of the Fourteenth Amendment of the Constitution. This amendment says that no state may "abridge" the privileges of any citizen, nor may any stat e deprive any citizen of life, liberty, or property without due process of the law. In 1954, fifty-eight years later, the Case of Brown v. the Board of Education of Topeka finally settled the debate of whether or not blacks and whites can receive an education integrated with or separate from each other. This time the Supreme Court unanimously ruled to overturn the Plessy v. Ferguson decision. In his opinion, the Chief Justice wrote, "We conclude that, in the field of public education, the doctrine of "separate but equal" has no place. Separate educational facilities are inherently unequal." The Brown case signaled the end of segregation of public places mandated by law.

Behaviour of Studied Plant Species in Terms of Heating Mitigation and Evapotranspiration

5 Discussion5.1 Weather ConditionssUpwind conditions during the season and the six measuring runs played a cardinal function for the procedure of this survey. As mentioned antecedently in respects to the survey of thermic imagination and specific conditions conditions were a requirement. The optimum conditions conditions for transporting out these measurings included clear sky, no air current and high values of PAR. These conditions slightly restricted the measurings as they were hard to be obtained for many yearss during the months from May until July. The measurement period was characterized by many yearss of cloud screen, rainfall and low temperatures and merely a few yearss of clear sky and high temperatures every bit good as high PAR values. The most restrictive factor was the cloud screen, as there were yearss with high temperature and besides there was cloud screen. However, there were yearss with clear sky and no air current but the PAR values were excessively low ( below 120 0 ?mol s-1m-2) , so that measurings could non be performed. Besides, it is of import to observe that the conditions conditions differed for each of the measuring dates as it was impossible to hold the exact same conditions every clip. Maes and Steppe ( 2012 ) had highlighted the limitation of conditions conditions in thermic imagination and the confining factor of cloud screen. However the consequences of the six successful measuring day of the months led to observations and decisions about the thermic behavior of the five studied works species.5.2 Behaviour of Studied Plant Species in Footings of Heating Mitigation and EvapotranspirationThe current survey have shown that all of the tried workss species had an effectual chilling potency by comparing to the bare dirt. Planted trays had ever lower surface temperatures than the control trays. This was besides supported by the statistical analysis which indicated important differences between mesocosms and control trays. Several surveies stated that one of the benefits of green roof workss is to maintain the temperature low ( Nagase and Dunnett, 2010 ; Teemusk and Mander, 2009 ) . Specifically, the four of the five species,Koeleria glauca, Lotus corniculatus,Dianthus carthusianorumandPhedimus floriferumhave been shown to hold lower temperatures than the controls trays for the full period of when the measurings were conducted. However, in the last two day of the months sing the measurings, theThymus serpyllumhad showed higher temperatures than the controls trays because the mini bush had died antecedently. While all workss of the monocultures had died many single species were able to last in combination with other species. However,Thymus serpyllumis considered a common green roof species ( Teemusk and Mander, 2009 ) . Besides, Jones ( 2002 ) had indicated thatThymusspecies frequently did non last. The ground for the bad public presentation ofThymusis still non clear. Although heat and drouth emphasis are known to hold a negative impact on the species, it is besides believed that works infections could be another cause for its bad public presentation. Sing the evapotranspiration, all the mesocosm systems showed to hold higher values than the control trays. System 5 (Phedimus floriferum )showed to hold the lowest evapotranspiration of the 15 mesocosms due to the facultative CAM metamorphosis of the species. The last two yearss System 4 showed the lowest evapotranspiration values sinceThymus serpyllumin the monocultures where they had wholly died off. Several surveies have been conducted to compare between green roof works species in monocultures and combinations in order to transport out and understand in which of the two is the most good. The surveies concluded that works mixtures were more effectual and good in footings of heating extenuation, evapotranspiration and H2O gaining control than monocultures and recommended for extended green roofs ( Lundholmet al. ,2010 ; Nagase and Dunnett, 2012, 2010 ) . This survey had concluded that System 7 a combination ofPhedimus floriferum( succulent ) andLotus corniculatus( leguminous plant ) was more effectual and good along with System 10 which is a combination ofPhedimus floriferum( succulent ) ,Koeleria glauca( grass ) andDianthus carthusianorum( herb)and can be considered as the best of the 15 systems in footings of extenuating warming effects. These systems showed significantly lower temperatures during most of the measurings. Systems 6( Phedimus floriferum + Koeleria glauca )and 14 (Phedimus floriferum + Koeleria glauca +Lotus corniculatus )had so followed with satisfactory consequences. These consequences are in general conformity with other surveies which showed that grass and herb or mixtures of these species are really suited to green roofs. Although they are less drought tolerant than succulent they are more effectual in footings of evapotranspiration and H2O keeping capacity ( Van Mechelenet Al., 2014 ) . Besides, the bulk of green roofs in North America and Europe are combinations of Sedum species or combinations of Sedum and grasses ( Wolf and Lundholm, 2008 ) . Lundholmet al. ,( 2010 ) had stated that the best combination for green roof is succulents, grasses and tall forbs. Since thei experiment this works mixture optimized most of the maps which were measured. Koeleria glaucacan maintain the H2O balance stable alternatively of intensive transpiration. Besides, its foliages are sclerenchymatous and about lush at the same time ( Kalapos T.,1989 ) . Furthermore, many herbaceous species are characterized by adaptative steps and could confront drouth ( Dvorak and Volder, 2010 ) . Some adaptative steps for Sedum species and stress-tolerant grasses and herbaceous are CAM photosynthetic tracts, H2O storage variety meats, succulent foliages which characterized the Sedum species, drought-avoidance ( bulbs and ruderals ) and woody growing. These and other morphological and anatomical characteristics could cut down the heat addition and H2O loss ( Wolf and Lundholm, 2008 ) . Grasss and forbs are characterized by low root H2O electrical capacity and/or drouth turning away which allow them to last in green roof systems ( Wolf and Lundholm, 2008 ) . It is besides deserving observing the importance in respects to the monocultures ofKoeleria glaucaandLotus corniculatusholding shown really good warming extenuation and chilling effects consequences. Besides combinations which included these species proofed to be really suitable. These species are both characterized by holding high evapotranspiration values andLotus corniculatusbesides being good of making high works screen due to strong vegetive growing. In respects to the Sedum speciesPhedimus floriferum,it is confirmed that it is really good for green roofs. Although it was frequently hotter than the other species likely due to its CAM metamorphosis it had a positive consequence on the other species.Phedimus floriferumwas presented with combinations which showed the best heat emphasis extenuation and kept the temperatures at low degrees during the measurement period. Several surveies investigatedSedumspecies as they are the most normally used for extended green roofs. Most of the surveies concluded thatSedumspecies can be characterized as ideal species and the best option for green roofs because of their facultative CAM metamorphosis, stress- tolerance and ability to re-sprout ( Butler and Orians, 2011 ; Farrellet al. ,2013 ; Nagase and Dunnett, 2012 ; Van Mechelenet al. ,2014 ) . Since none of the deep-rootedPhedimuspersons died in the survey, it must besides be noted that the high continuity of the species is another positive fac et.5.3 Plant Cover and Temperature of Studied Plant SpeciesIn current survey that have been examined in respects to the dealingss between the works screen and average temperatures of the mesocosms, there was the premise that the works screen would had influenced the temperatures. It was concluded that temperatures were so slightly influenced by the works screen, the higher the works cover the lower were the temperatures. This had so led to the decision that the species which are characterized by distributing via vegetive growing such asPhedimus floriferumandLotus corniculatusare advantageous for green roofs. A high screen and leaf wonts of workss can besides be good.5.4 Restrictions of the StudyAs antecedently stated the chief problem/limitation during measurings was the clip consequence on tray temperatures. In order to cut down the job of different heating throughout the twenty-four hours, measurings were carried out at midday when the radiation and the temperatures usually reach a tableland. Besides, dry and wet â€Å" unreal foliages † were used and exposed to the same environmental conditions ( air temperature, radiation, wind velocity ) as the trays in order to avoid theoretical appraisals of baselines. It was observed that the temporal temperature gradient decreased when the measurings were carried out at midday. By this, the clip consequence was partially solved but it still existed. Furthermore, for most of the measuring day of the months at that place was a good convergence between the temperatures of unreal foliages measured by the usage of thermocouples and the IR-camera. Thus the emissivity needed non to be adapted. As mentioned antecedently, the thermic imagination was performed within two hours and this period of clip could hold resulted in big differences in ambient temperature or the consecutive warming of the trays. One solution was to cut down this clip period but due to the high figure of trays it was about impossible to execute the thermic imagination in a shorter clip length. Maes and Steppe ( 2012 ) had besides indicated this restriction in thermic imaging so they alternatively highlighted the clip devouring process of thermic imagination. Another solution to execute thermic imagination of all trays in one spell is the usage of aircraft but this method leads to a instead harsh declaration of images ( Leuzingeret al. ,2010 ) . It is besides of import to observe that the clip consequence had complicated the finding of the important differences between the systems, due to the high criterion divergences. However, the consequences of this survey clearly indicated important differences between the systems and the control trays. Besides, it can be concluded that systems equipped with species such asKoeleria glaucaandLotus corniculatusshowed satisfactory consequences and could be characterized as being appropriate works species. The restriction as stated above in respects to the clip consequence besides led to the determination to maintain the emissivity to a default value of 1 since the survey was concerned in temperature differences between the systems and non in the absolute temperatures of the objects ( works leaves, dirt substrate, pebbles and lava ) . However, as mentioned in subdivision 3.3.1 during March and April 2014 ( before the measurings started ) several efforts were made in order to define/calculate the emissivity of the studied works species but because of the complexness the efforts were kept to a lower limit. It is deserving observing that most surveies on works temperatures set emissivity to a default value and that there are merely little differences between dirt and works emissivities ( Leuzinger and Korner, 2007 ; Maes and Steppe, 2012 ) . It would besides be interesting to analyze day-to-day rhythms of leaf temperatures particularly inPhedimussince it is a facultative CAM species. Unfortunately another restriction of this survey which wasn’t conducted was that this survey didn’t examine the day-to-day behavior in footings of the temperature and transpiration of the workss. If the restriction had been conducted the behavior ofPhedimuswould hold besides been researched in order to detect its transpiration.5.5 Inventions of the StudyDespite the restrictions mentioned above that had non been conducted the current survey is the first in which a high figure of replicated green roof mesocosms were researched. Every system had eight replicates and the control trays were seven. This high figure of replicates is sufficient for stand foring temperature measurings, which had ne'er been studied on green roof works species. The measurings were carried out from May until July in 2014. This long measuring period allowed more observations about the studied works species and their thermic behavior over clip in different conditions conditions and state of affairss. The usage of IR-thermometry can be considered as another invention since this method is new and it started to be used in recent old ages. However, this could be seen as a hazard since there are no fixed protocols available for IR-thermometry on workss. As antecedently mentioned, the usage of thermic imagination and infrared cameras enables the observation of thermic conditions of the objects in item. The technique of infrared thermometry has started to be normally used because of its truth. Infrared cameras are now being used more and more by works scientists because the costs of the equipment has been diminishing. Another of import factor is the usage of image analysis to derive mean, lower limit and maximal temperatures of selected objects and it has besides brought in a new method in respects to research. The corresponding package of the camera, IRBIS ®, has been a really helpful tool in order to research the temperatures of the studied workss. As a farther affair in respects to the statistical analysis that was performed in order to place important differences between the mesocosm systems, and controls and besides between the different types described as advanced because so many statistical trials were carried out for each day of the month of measurings in order to compare the systems.6 DecisionIn the last decennaries, the effects of planetary heating have become progressively seeable. One technique used to extenuate urban heat is the building of â€Å" green roofs † , a method that is progressively used in many states. Green roof workss have the capableness to change the microclimate outside and inside of edifices. A new method to look into the temperature and accordingly the chilling potency of workss is infrared thermometry. Thermal imaging utilizing infrared cameras enables the observation of thermic conditions of the objects in item. Topographic point measurings of foliage temperatures utilizing thermocouples a re inferior to IR-thermometry but the latter attack has restrictions, excessively. The survey was carried out to look into the effectivity of five commonly used green roof works species:Koeleria glauca( a grass ) ,Lotus corniculatus( a leguminous plant ), Dianthus carthusianorum( a herb ) ,Thymus serpyllum (a low turning bush ) andPhedimus floriferum( a succulent ) . The undermentioned three hypotheses were tested: – The workss have an effectual chilling potency as compared to the bare dirt. – TheSedumspecies,Phedimus floriferum,could hold a positive consequence on the other species and could cut down heat emphasis. – Plant mixtures of different species are more effectual than monocultures. The overall aims of this survey was to i ) Compare the deep-rooted trays with control trays ( au naturel dirt ) in order to look into the chilling potency of workss. two ) Examine the effectivity ofPhedimus floriferumin footings of evapotranspiration, heat consequence extenuation and possible positive consequence on the other species. three ) Compare the works mixtures with monocultures to place important differences. The consequences in general supported the first hypothesis. It had particularly supported the speciesKoeleria glaucaandLotus corniculatusand some of the mixtures with these species holding shown to hold significantly lower surface temperatures than the controls trays and some of the deep-rooted mesocosms for the whole measuring period. The consequences in respects to the 2nd hypothesis was besides supported.ThePhedimus floriferumso had a positive consequence on the other species as the combinations with the species kept the temperatures at lower degrees during the measurement period. SincePhedimusis a extremely drought stress-tolerant and relentless species, it had a positive consequence on the ecological services of green roofs. The consequences besides lead to the credence of the 3rd hypothesis that works mixtures are more effectual than monocultures since the best systems in footings of extenuating the heat effects were works mixtures. However, the survey besides faced some restrictions such as the clip consequence on tray temperatures and the proper accommodation of emissivity values. Several efforts were made and several methods were applied in order to turn to those limitations. Harmonizing to the literature, old surveies had faced the same restrictions. In order to cut down the clip effects during measurement runs of a high figure of replicates, high scaffolds should be used from which all objects can be monitored in one spell. However, due to the big field of position the low declaration of images would hold been a job. Taking exposure of all the objects at the same clip had its advantages in that many images could be taken over clip, e.g. to analyze day-to-day temperature rhythms of works surfaces. This could be characterized as an mentality which should be investigated farther by similar experiments in the hereafter, in order to see whether it helps the survey to minimise or extinguish similar restrictions and limitations and besides to lend to this current research.

Free Essays on The Comparative Analysis Of The Computer History In The USSR &USA

Introduction Once in a lifetime a new invention will come about to touch every aspect of our lives. Such a device that changes the way we work, live, and play is a special one, indeed. A machine that has done all this and more now exists in nearly every business and one out of every two households. This incredible invention is the computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40 years it has changed the society. From the first wooden abacus to the latest high-speed microprocessor, the computer has changed nearly every aspect of people’s lives for the better. The very earliest existence of the modern day computer’s ancestor is the abacus. These date back to almost 2000 years ago. It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to â€Å"programming† rules that the user must memorize, all ordinary arithmetic operations can be performed. The next innovation in computers took place in 1694 when Blaise Pascal invented the first digital calculating machine. It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal’s father who was a tax collector. In the early 1800’s, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would need. It was programmed by and stored data on cards with holes punched i n them, appropriately called punchcards. His inventions were failures for the most part because of the lack of precision machining techniques used at the time and the lack of demand for such a device. After Babbage, people began to lose interest in computers. However, between 1850 and 1900 there were great advances...

Discussion Post Movie Review Example | Topics and Well Written Essays - 500 words

Discussion Post - Movie Review Example It is important to note and mention that he involves humor thus introducing comic relief ensuring the audience relaxes to engage during the presentation. Another advantage and merit is that David Gallo uses hands and gestures to make points clearer and show vigor during the presentation (Dunlap & Lowenthal, 2011). This is to mention that the use of body language enhances the ease of putting the message across thereby stressing on the important issues and points. In some instances, the speaker uses short sentences which in conventional knowledge are used to portray tension. Thus, the fact that David Gallo uses short sentences at the end of the presentation is akin to introducing tension or some sort of edginess in the presentation. In all fairness and respect, the use of short sentences is a short coming of the presentation. Similarly, there is less use of rhetoric questions in the presentation which means that the presentation translates to a monologue. Thus, few uses of rhetoric que stions reduces the presentation to a one man show. From the outset, it is notable that he uses a fast paced approach of talking in his speech. This is so because one easily notes that he speaks in a relative fast pace. It is important to note and mention that the voice of Sir Ken Robinson is commanding and authoritative in a way and manner. In terms of his use of stage, he does not move around the stage and instead stands in one place. This is to say that he does not engage the whole audience effectively. Secondly, he maintains eye contact with the audience thus improving the appeal of the audience and attract their attention. Equally interesting in the presentation of the speaker is that he maintains facial expression which are used to mean and imply different things. For instance, during the times of humor, he contorts his face in a friendly way therefore engaging the audience during the light moments. On the other hand, this presentation is non-interactive because the speaker

How different was Sparta from other Greek States Essay

How different was Sparta from other Greek States - Essay Example Some scholars feel that other states felt that Sparta was too obsessed with war and power and that this is the reason why this stated paid attention to the development of a strong army and their involvement in war. Additionally, this is the city that gave a woman the right to conduct business and train for war. Resultantly, other states felt safe to associate with Sparta especially during periods of war. A deep analysis of the Sparta state will unveil the difference of this state compared with other states. The Sparta social structure comprised of three categories of individuals; the citizens, Periokioi and the Helots. The citizens formed the large group of native citizens who were the original habitants of the land. This group of people formed the loyal part of the society. They formed part of the army and had the absolute right to own any kind of property. In the structure oligarchy that existed, the citizens were the superior people that dominated the society. The Periokioi were a group of people who had migrated to this society. They formed the intermediate group that separated the inhabitants and slave. Since this group was way below the habitants, they were not allowed to partake in military action but could own land and control business. They trusted than the minority group of the Helots in this society. The Helots were those people who had entered the country and did not have the right to own land nor participate in war. The formed the source of labour and worked in the lands a nd business enterprises in the society. As observed, the country applied oligarchy unlike other nations such as Athens that were fully democratic1. On this note, this was a good environment only for the original habitants while the aboriginals were treated as inferior beings. The military system in Sparta was stronger than any other in the whole of Greece. The Original citizens in this state were compulsorily supposed to attend military training at their early age. Unlike in

Ijarah and conventional lease contracts Assignment

Ijarah and conventional lease contracts - Assignment Example The main aim of this research is to give detailed characteristic of conventional leasing system and Ijara, to disclose differences and common features and discuss the variety of options and applications of both(Usmani). â€Å"Ijarah† in the language of banking and finance can have two simple definitions â€Å"hiring† and â€Å"leasing† which are commonly interchangeable, but the origin of that word comes from Arabic ‘ajara’ which means ‘recompensing’ or ‘rewarding’. From the view of the Islamic banking system Ijarah is referred to Islamic contract of leasing of property and equipment, of land to be leased to a client for rental payments or stream payments. From the view of Islamic banking system Ijarah is referred to a certain leasing contract of property and equipment or land which is leased to a client for rental or stream payment(Open to comparison). Ijarah word is to symbolize a contract between the two sides – the lessee and the lessor where the lessor is presented as an owner of a property of any kind and he gives permission to a lessee to make use of the usufructs of the property in question with terms agreed about the leasin g and the rental period. According to the fact that Islamic countries cannot be disconnected with their religion Ijarah contract has gained the permission of the Shari’ah due to several authorities(Nizram): The both parts of the contract are to be provided with certain conditions: they must be able to take responsibilities as well as being in sound mind and having reached the age puberty and the majority age. Secondly, the must not be banned to deal with their property, they need to present stability and stay far from being declared bankrupt or wasteful. Both of the sides should not be under pressure re any kind of compulsion. There are four conditions set up for property: first and foremost property must be owned by a lessor, it has to be available for immediate use, it is supposed to be delivered to the lessee and

Common Inventory System Problems & Solution Essay Example for Free

Common Inventory System Problems Solution Essay Symptoms: Preoccupation with the forecast within the execution time frame. Typically, companies begin altering their forecast management processes when addressing supply chain performance. But this is unwise without understanding the nature of your demand and the root causes of forecast errors. When forecast accuracy is overemphasized, fill rates and inventory turns don’t improve, even when forecast accuracy does. No measure of customer service or inventory turns. Customers must be satisfied on an ongoing basis for a company to achieve long-term sustainability. Yet, inventory managers often have no idea how well customers’ needs are being met. Similarly, without knowing how quickly inventory moves through the value-creation-and-delivery system, a company won’t be able to manage inventory levels. Daily planning is based on a back order report. This is an entirely reactive model. Today’s fast-paced marketplace requires proactive inventory planning to meet current demand. Customers will switch to a competitor if their needs are consistently unmet in the time frame they dictate. Solutions: Mandatory tracking of fill rate and inventory turns for all product lines. Product managers should know these measures at all times. Fill rate should be measured daily, while inventory-turn measures will vary based on sales and production cycles. The important thing is that managers are both tracking and working to improve these rates. Develop realistic forecast-error measures. Developing realistic measures for how much forecast error you can tolerate without a SKU stock-out is essential. Typically, companies estimate plus or minus 10 for this measure, which equals about two days worth of inventory-a miniscule amount considering that companies often have weeks or months worth of inventory. Effective forecast management and inventory planning require accurate data, so accurate forecast error measures are a must. Mistake No. 2: Having unqualified employees manage inventory Symptoms: A sentiment that â€Å"our business is different because (fill in the blank).† Every company has inventory planning challenges, such as variable demand. No business is so different that it would not benefit from strategic  inventory management. Decentralized inventory management. If warehouse managers, office clerks, and other employees without specific inventory-management training are making inventory-management decisions, then it is certain that wasteful inventory is piling up throughout the system. Usually, this model reflects a company with no clear goals or strategy for inventory planning. Lack of formal training program or professional peer interaction. Inventory management is a professional skill that requires upfront and ongoing education. Emphasizing â€Å"buying† over planning. Buyers make purchases, but planners make strategic decisions to meet goals. Thinking of inventory planning from a purely â€Å"buying† point of view means opportunities for improvement and financial benefits will be overlooked—daily. Solutions: Recognize that inventory management requires professional job skills, and hire and train accordingly. Just as a company with hundreds of thousands of free dollars on its balance sheet would hire professional investment advisers, a company with hundreds of thousands of dollars in inventory should have professional inventory managers. Assign accountability for inventory management. Often, companies can’t answer the question, â€Å"Who is in charge of making sure inventory levels support strategic goals?† If no one is, then these inventory planning goals will never be met. TOP 5 SOLUTIONS: 1. Use reorder points on inventory items to keep purchasing streamlined and inventory manageable. Reorder points (otherwise known as min. and max. levels) are the best method for making sure you have the right amount of inventory in your warehouse at all times. If you have too little inventory you could lose out on sales, but if you have too much your cash is tied up in inventory that will not be sold. One of the biggest problems many companies have is managing their cash. A quick way to solve that from an inventory standpoint is by making sure you have set the appropriate reorder points for your business. 2. Spend money on specialized training for mission-critical software. Companies with a lot of inventory spend thousands of dollars on software they need in order to manage and track their items as  they move all over the world. This software manages millions of dollars’ worth of assets. After spending so much money on software, some companies don’t want to spend a f ew thousand dollars extra to buy the specialized training they need to implement the software. This is a big mistake because this software won’t do you any good if you don’t spend a little bit more to learn how to use it. If you try to learn your software on your own you may suffer for months before you learn the basics of how it works. 3. Rearrange the warehouse to set up for picking efficiencies. Sometimes trainers see mistakes that are so obvious you would think they’d be corrected immediately, but warehouse managers may be too distracted to notice them. We often see 100,000-square-foot warehouses that are organized inefficiently. These companies could save themselves large sums of money by making a few changes to where they place their inventory. The items that you sell the most or send out the most should be right next to the shipping dock. This keeps your employees from having to walk all the way across the warehouse to pick them up every time you are going to send them out. As companies grow, sometimes they just randomly put things where there is sp ace. This works for a little while, but as you grow you need to think about efficiency because the minutes that your employees spend driving around the forklift cost you money. 4. Take time to get to know your technology so that you can use all the functionality. Rarely will a company use all of the functionality their software provides. Most of the time there is more that the software can do for you that you haven’t explored. Software companies always hear from their customers about which features they want added to the software when a lot of the time the features are already there. The more features that you use in the software the more effective you can be in managing your inventory. You should either assign someone within the company to learn the software functionality or pay someone to come in and teach it to you. 5. Stop doing yearly physical inventories and move to a more regular, smaller cycle counting and reconciling routine. Businesses used to shut down for a day to a week each year to go into their warehouse and physically count everything to make sure that it matched the information in their software. This practice is mostly outdated because of the amount of time and money it takes. Doing these checks in smaller, more regular cycles keeps a company from having to shut down. We recommend picking one section each day to check  your product levels against the information from your inventory software.

The Nature Of Subsonic Airflow

The Nature Of Subsonic Airflow The nature of subsonic airflow over aerodynamic sections and over the aircraft at large must be considered, including the forces that result from such airflow and the effect these forces have on the aircraft, during steady flight and during manoeuvres. Although there are various kinds of pressure, pilots are mainly concerned with atmospheric pressure. It is one of the basic factors in weather changes, helps to lift an aircraft, and actuates some of the important flight instruments. The pressure of the atmosphere varies with time and location. Due to the changing atmospheric pressure, a standard reference was developed. The International Civil Aviation Organization (ICAO) has established this as a worldwide standard, and it is often referred to as International Standard Atmosphere (ISA) or ICAO Standard Atmosphere. Large modern passenger aircraft can weigh in excess of five hundred thousand kilograms when they fly with a full fuel and passenger load, yet this combined mass is lifted into the air with apparent ease. Modern jet fighter aircraft can exceed the speed of sound and are very manoeuvrable. Thrust, drag, lift, and weight are forces that act upon all aircraft in flight. Understanding how these forces work and knowing how to control them with the use of power and flight controls are essential to flight. Task 1 A, The international standard atmosphere is an atmospheric model of how the pressure, temperature, density and viscosity of the earths atmosphere change over a wide range of altitudes. ISA model divides the atmosphere into layers. http://en.citizendium.org/images/thumb/2/26/AtmTempProfile.png/350px-AtmTempProfile.png Atmospheric Layers Figure 1 source= http://www.google.co.uk/imgres?q=international+standard+atmosphere+diagramum=1hl=ensa=Nbiw=1366bih=667tbm=ischtbnid=IWsOmm4pNQN12M:imgrefurl=http://en.citizendium.org/wiki/Atmospheric_lapse_ratedocid=IVZzKSSCCNR_KMimgurl=http://en.citizendium.org/images/thumb/2/26/AtmTempProfile.png/350px-AtmTempProfile.pngw=350h=385ei=aImJUMrXNo2Y1AWj04G4Dwzoom=1iact=hcvpx=369vpy=138dur=273hovh=207hovw=188tx=145ty=90sig=113637047184909608346page=1tbnh=137tbnw=125start=0ndsp=19ved=1t:429,r:1,s:0,i:72 Troposphere Troposphere contains about 80% of atmospheres mass 99 % of its water vapour and aerosol. The temperature of the troposphere generally decreases as the altitude increases. The reason for the temperature difference is that the absorption of the suns energy occurs at the top of the atmosphere cooling the Earth, this process maintaining the overall heat balance of the Earth. Stratosphere Stratosphere is the second important layer of the atmosphere. It is separated from troposphere by tropopause. It takes about 12 to 50km of the atmosphere. The temperature increases as the altitude increase. At the top of the stratosphere the thin air may attain temperature close to 0c. this is happening because of the absorption of UV radiation from the sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions and the stratospheric lacks the air turbulence that is so prevalent in the troposphere. Stratosphere is completely free of clouds and any other forms of weather. This layer is very good for the flights to fly as it is above stormy weather and has strong, steady and horizontal winds. Stratosphere is separated from the mesosphere by the stratopause. Mesosphere This layer is the third highest layer of the atmosphere. This layer takes 50 to 80km above the surface of the Earth. It is separated from the stratosphere by stratopause and from the thermosphere by mesopause. Temperature drops when the altitude increases to about -100. Mesosphere is the coldest of all the layers as it is colder than Antarctica. This layer can freeze water vapour into ice clouds so that when the sunlight hits them you can see it after sunset. It is also the layer where the meteors burns up while entering the Earths atmosphere. Thermosphere Thermosphere is the outer layer of the atmosphere. Mesopause separates mesosphere from thermosphere. In this layer the temperature rise continually to well beyond 1000 The few molecules that are in this layer receives an extraordinary amount of energy from the sun therefore warms up the layer making it hotter. Air temperature however is the measure of the kinetic energy of air molecules, not of the total energy stored by the air so the air is so thin within the thermosphere, such temperature values is not comparable to other layers. Although the temperature is very high we would feel very cold because the total energy of only a few air molecules residing there wouldnt be enough to transfer any heat to our skin. Ionosphere After thermosphere its Ionosphere. This area is full of ionized air extending from 80km above the Earths surface altitudes of 600km and more. Technically Inosphere is not layer.In this region/area the suns energy breaks molecules and atoms of air as the energy is so strong and hot leaving ions and free floating electrons. Ionisation of the air molecules is produced by UV radiation, other radiation from sun and cosmic rays. Ionosphere is the region where aurora appears. B, Source figure 2= http://www.google.co.uk/imgres?q=turbulent+and+laminar+flowum=1hl=ennoj=1tbm=ischtbnid=-FJHlXUJvGV3qM:imgrefurl=http://www.daviddarling.info/encyclopedia/L/laminar_flow.htmldocid=aHyeoqPiHZRJqMimgurl=http://www.daviddarling.info/images/laminar_flow.jpgw=280h=171ei=LIqJUL2YKcLX0QXjxoBIzoom=1iact=rcdur=364sig=113637047184909608346page=1tbnh=136tbnw=224start=0ndsp=16ved=1t:429,r:6,s:0,i:87tx=89ty=37biw=1366bih=667http://www.daviddarling.info/images/laminar_flow.jpg Laminar flow Turbulent flow Laminar flow is good for aircrafts as there is less drag and much easier to create lift. It is a very smooth and uninterrupted flow of air over the contour of the wings and other parts of an aircraft. Laminar is found at the front of the streamlined body. An air foil is designed for minimum drag and uninterrupted flow of the boundary layer is called a laminar air foil. The pattern of the flow involves of layers. Particles in each layer do not interfere with other particles in the other layer which makes it smooth flowing layers. There is no difference in velocity between the layers. Boundary layers are thinner at the leading edge of the aircraft wing and thicker towards the trailing edge, such boundary has laminar flow in the leading portion and turbulent flow at the trailing portion. There is more drag than laminar. In this flow the direction and velocity changes continuously. Particles move opposite to other particles causing collision which makes turbulence. The trust need to be more counteract the flow of turbulence. Reynolds number is dimensionless quantity associated with the smoothness of flow of air/fluid. At low velocity the flow of a fluid/gas is laminar; the fluid/gas in the layers of laminar flow gives rise to viscosity. As the gas flows more rapidly, it reaches a velocity known as critical velocity. This is when the motion changes from laminar to turbulent. Viscosity is the resistance of a fluid to flow. The coefficient of viscosity of gases increases with increasing temperature. Task2 A, Bernoullis principle As the velocity of the gas increases the pressure exerted by that fluid decreases. The aeroplane gets part of the lift from Bernoullis principles. This principle says that increased air velocity produces. When the Bernoullis principle is applied the fluid has these qualities Fluid flows more smoothly Fluid flows without any swirls(eddies) Fluid flows everywhere through the pipe Fluid has same density everywhere As the fluid passes through a narrow or wide pipe, the velocity and pressure of the fluid vary. As the fluid flows through a narrow pipe the flow quickly. This principle says that fluid flows more quickly through the narrow section, the pressure actually decreases than increasing. Air passes faster over the top of the cambered wing and results in lower pressure. The top of the wing is curved, the air that passes over the top of the wing moves faster because it travels a greater distance in the same amount of time as compared to the air that passes underneath the wing. Lift is created because the air under the wing is slower and exerts higher air pressure so the difference in the pressure creates the lift. Venturi principle An inverse association of gas pressure, velocity of flow, and restriction of passage. This principle states that the pressure drop distal to a restriction can nearly be restored to the pre restriction pressure if there is a dilation of the passage immediately distal to the stenos is, with an angle of divergence not exceeding 15 degrees. In venture tube the area decreases the velocity increases and the pressure decreases, and vice versa as well. So the difference in pressure creates lift. B, Total drag Total drag is the sum of all of the aerodynamic forces which act parallel to, and opposite to, the direction of flight also it is the total resistance to the motion of the aircraft through the air.it is the sum of other drags acting on the aeroplane which are parasite drag and induced drag. Induced drag is the drag created by the vortices at the tip of an aircrafts wing. Induced drag is the drag due to lift. The high pressure underneath the wing causes the airflow at the tips of the wings to curl around from bottom to top in circular ms in a trailing vortex. Induced drag increases in direct proportion to increases in the angle of attack. the circular motion creates a change in the angle of attack near the wing tip which causes an increase in drag. The greater the angle of attack up to the critical angle, the greater the amount of lift developed and the greater the induced drag. parasite drag the parasite drag of a airplane in the cruise configuration primarily of the skin friction, roughness and pressure drag of the major components. There is usually some additional parasite drag due to such things as fuselage upsweep, control surface gaps, base areas and other extraneous items. Since most of the elements that make up the total parasite drag are dependent on Reynolds number and since some are dependent on mach number, it is necessary to specify the conditions under which the parasite drag is to be evaluated. In the method of these notes, the conditions selected are the mach number and the Reynolds number corresponding to the flight condition of interest. This drag comprises skin, form drag and interference drag. Skin friction drag is a friction force between an object and the air through which it is moving produce skin friction drag. Form drag is when the airflow actually separates from the surface, eddies are formed and the streamline flow is disturbed. The turbulent wa ke so formed increase drag this is form drag. Interference drag is caused by flow interference at the wing and other such junctions. This interference leads to the modification of boundary layers and creates a greater pressure difference between the for and after area on the surface concerns. This in turn leads to greater total drag. Fairing or additional fillets are used to streamline these intersections and decrease interference drag.

It doesnt change significantly with an angle of attack of the airfoil section, but increase moderately as airspeed increases. Is the drag incurred as a result of production of lift. Higher angles of attack which produced more lift also produce increased induced drag. In rotary wing aircraft induced drag decreased aircraft airspeed. The induced drag is the portion of the total aerodynamic force which is oriented in the direction opposing the movement of the airfoil.
