Euro Behaviour Essay Example | Topics and Well Written Essays - 2000 words

Euro Behaviour - Essay Example From the report it is clear that  economic performance of a trade block depend more on individual countries performance. In our analysis, we intend to evaluate euro’s performance and as such will rely more on the overall activity within member countries. Euro is not political affiliated and thus depend in multi-nation policies regarding the member countries economic performance. When crisis in economic activity within one trade block occur, the effects easily spill to the global economic and asset market. The European Union, as a trade block, has frequently suffered such.According to the report findings  the links in international financial and asset markets are key determinants of a currency’s exchange rate. Single currency or states supremacy cannot influence the rates that her currencies are accorded. Macroeconomics teaches that multiple factors are put into play in regard to determining a currency’s worth in the international market. Individual states cur rency is rated on a scale that is unanimously accepted within the trading scope against a common denomination; majorly the U.S dollar, yen or the euro. However, the rates are never constant varying on the prevailing economic performances as determined by the World Bank. ‘Purchasing power parity’ (PPP) compares rates of trade and prices within a state. Projections of future interest rates of a currency relative to nominal interests are determined by the interest rate parity. (Cumby and Obstfeld, 1982, 1-2). Therefore, at the macro and micro level performance of an economy, the policies made always have an impact to the valuation of her currency. However, the determination of these indices within an economic block like the EU is not dependent on a single country but rather on sum of the overall economic performance of the economic block. The Euro use has expanded very much within the EU region and is now estimated to be in used throughout

Learning Disabilities Essay -- A Level Essays

Learning Disabilities Eleven-year-old Anna is outgoing and bright. She attempts to work hard, but her progress in school has always been slow. She is a year behind her peers, particularly in her English class and her teachers have slowly begun to reduce their expectations of her. Her parents are worried because her confidence for learning is decreasing, and there is less motivation for her to do homework and class assignments. A psychologist found that her intelligence is in the gifted range, but she has difficulty in making out written symbols. It is easy to make the assumption that Anna seems merely as a child who is slow intellectually, but when taking a closer look, it shows that she is just as intelligent but happens to suffer from a learning disorder. Students with learning disorders have brain impairments that make it difficult for them to acquire skills and knowledge accurately and fast enough to keep pace with average academic progress (Encarta, 2003, p.1). The purpose of this research paper is t o investigate the causes of learning disorders, various types of disabilities, their causes, and finally how in today’s modern era assistive technology is able to reduce the frustration of students and increase their level of performance. Defining Learning Disorders/Disabilities The IDEA (The Health & Fitness Association) 1997 Definition of Learning Disabilities is: â€Å"A disorder in one or more of the basic psychological processes involved in understanding or using language, spoken or written, that may manifest itself in imperfect ability to listen, think, speak, read, write spell, or to do mathematical calculations.

Compare how a sense of claustrophobia is built up in the Handmaids Tale and an Evil Cradling

Margret Atwood's fictive autobiography ‘The Handmaid's Tale' And Brian Keenan's autobiography, ‘An Evil Cradling' documenting his kidnapping by fundamentalist Shi'ite militiamen both present a sense of claustrophobia. Each novel presents tional. strophobia Keenan' the manifestation of claustrophobia within the protagonists. ‘An Evil Cradling' presents Keenan's physical claustrophobia as a hostage and the emotional entrapment. Both authors successfully create a sense of claustrophobia whilst exploring the different situations of both protagonists. Both Offred and Keenan's lifestyles appear even more claustrophobic in contrast to their previous lives. There is an asymmetry in the presentation of a sense of claustrophobia within and between the two novels. Whilst on the one hand, both writers deal with the notion of claustrophobia as having a negative consequence on their lives. On the other hand the life of the main protagonists before their captive state is presented with considerable differences. These differences are exemplified in the opening chapters of both texts. Keenan in his exploration of life before captivity seems to suggest life was not all that tranquil and certainly not without its problems before he was taken captive in the Lebanon, where one might imagine the root of all his problems with claustrophobia began. In the preface Keenan states, â€Å"I was brought up in that harsh, divided landscape of Northern Irish, working class and I went into with all its baggage. † Furthermore he claims in his first chapter, â€Å"Before I left Belfast, I had been torn with a desperate kind of love and distaste for my place. Both statements from the two parts of Keenan's book, show that his life, as he puts it himself, was a type of ‘cul-de-sac. ‘ This metaphor for a dead-end shows that Keenan was no more free in his native Ireland, so much that he was forced to seek mental comfort elsewhere. The entire opening chapter of an evil cradling highlights Keenan's disconnection with his country and how he felt trapped and a sense of c laustrophobia in a place so familiar to him. Contrastingly, Atwood presents her protagonist as having a far more affectionate, possibly ‘rose tinted' view on her life before taken into captivity. In Atwood's ‘A Handmaid's Tale' Offred conveys a large amount of nostalgia towards her past. In the opening chapter Atwood contrasts the senses of the past. The lights are vividly described as â€Å"a revolving ball of mirrors, powdering the dancers with a snow of light. † Atwood chooses this poetic metaphor to show her fondness towards previous times. Atwood describes the simplicity of the lights under the regime â€Å"The lights were turned down but not out. † Offred's feelings of extreme claustrophobia are exacerbated through the juxtaposition of the former senses. In Offred's case she is more sensitive towards these feelings of freedom. Offred is a victim of gradual entrapment that has been apparent in her society for many years; chapter 28 reveals the gradual oppression of women â€Å"Things continued in that state of suspended animation for weeks†¦ Newspapers were censored†¦ roadblocks began to appear, and identipasses†¦ † by stripping women of their political and social rights the Gileadean regime came to power. Offred uses listing to highlight the continuous changes in society, specifically directed at women, showing her own shock and resentment towards her gradual confinement. Offred does not only demonstrate nostalgia towards her past in the opening chapters. Atwood constantly uses similes throughout that are reminiscent of the past. These similes present an escape from the routine regime; they often involve the senses which allow Offred to escape the regime by remembering and juxtaposing elements and senses of the past. † It's almost like June,† Offred shifts in mental perspective via association of seasons, Offred's memories of the seasons are superimposed over Gilead's charade of normality, it is as though Offred escapes into her own private narrative underneath her imprisonment as a handmaid her recollections act as freedom from the past. Both Offred and Keenan's sense of claustrophobia is intensified by the way that their human rights are no longer recognised and they have no freedom of choice. Keenan's beard is used in ‘The Devil's Barbershop' to symbolise his dignity and freedom of choice. Keenan is very reluctant to have his beard shaved off; his behaviour becomes the manifestation of claustrophobia. He becomes attached to his beard and it symbolises his freedom of expression, â€Å"I've had this beard for too long for some halfwit who thinks he owns me to make me what he wants me to be. Throughout this passage Keenan uses long sentences that highlight his heightened emotions, Keenan's aggressive tone towards his captors also shows his reluctance to change, Keenan's identity is displayed through his beard and similarly to Offred he is being made to conform and accept his claustrophobic surroundings. In â€Å"The Handmaid's Tale† Offred is defined by her uniform, and looses her previous identity. This expresses that in Gilead their lives have become so claustrophobic that even their ability to express themselves has been repressed. Offred feels trapped in a system which rigidly controls women. The colour coding of women's clothes indicates that in this society their individual identities are lost in prescribed roles. â€Å"Everything except the wings around my face is red: the colour of blood, which defines us†¦ a sister, dipped in blood. † Atwood uses this negative metaphor to highlight Offred's feelings towards loosing her individuality. Offred's uniform in addition acts as a physical restriction, â€Å"The white wings†¦ they are to keep us from seeing, but also from being seen. It is made apparent that their clothes are also a way of physically restricting them as way of control, deliberately designed to limit the Handmaids view. The blood red is a constant reminder of the vilification of women in Giliadean society. ‘Blood red' is symbolised throughout the novel and acts as a constant reminder to Offred's role in society, although her role as a child barer allows her more freedom unde r the regime it is also the one thing that traps her. The description of the characters' surroundings and routines present a sense of claustrophobia, Offred's account of going out and doing the daily shopping illustrates this. Under the Gileadaen regime the Handmaids never went out unaccompanied, this partnership system provided both chaperones and spies. Offred considers the image of both women dressed identically in red, thinking of them as doubles, both visually and in circumstances. â€Å"The truth is that she is my spy, as I am hers. † Each woman traps the other. However, a suggestion of freedom is present in the structure of the two novels. For Keenan, his ability to let his mind wander in times of extreme captivity has been vital to his survival. Keenan changes tenses abruptly, from describing the cell, to a present time, showing the way in which his mind jumps, to escape his present situation. However, in â€Å"Into the Bread Basket† Keenan's senses were shut down by the â€Å"tight confinement of the tape† which â€Å"will not let my mind escape. † Now that even his mind cannot escape he feels as if a â€Å"riot is bursting out within my senses† which further reflects how his repressed senses are desperate to escape the confinement, without his freedom of mind Keenan finds himself completely trapped. Correspondingly, Offred is able to escape into her private world of memory and desire. Offred uses storytelling as a means of personal survival her narrative is the only way of bridging the gap between an isolated self and the world outside. â€Å"It is also a story I am telling, in my head, as I go along. † Offred is able to escape the intense feelings of claustrophobia through expressing her feelings. Atwood chooses short sentences to emulate the natural nature of speech resulting in a flowing structure. Fear plays a main role in increasing the sense of physical claustrophobia experienced by both Keenan and Offred. In ‘into the bread basket' Keenan uses imagery that creates associations with death â€Å"I am being embalmed and mummified† and â€Å"I am going back to the coffin. † This demonstrates how in such claustrophobic conditions where all his senses have been effectively shut off he is completely helpless and that in these cramped dark conditions the difference between life and death becomes uncertain. Keenan carries on this extended metaphor in the oxymoron â€Å"a living corpse† this again reflects the negative experience of being in such claustrophobic conditions. Finally, both authors have used literary and structural techniques to reveal the many ways in which claustrophobia can be created and intensified. Although the two protagonists' situations are very different, as Offred lives a controlled and limited life and Keenan one of absolute entrapment they show many similar traits and emotions triggered from their individual feelings of claustrophobia.

The Domestication of the Apple Gift from Central Asia

The domestic apple (Malus domestica Borkh and sometimes known as M. pumila) is one of the most important fruit crops grown in temperate regions worldwide, used for cooking, eating fresh, and cider production. There are 35 species in the genus Malus, part of the Rosaceae family which includes several temperate fruit trees. Apples are one of the most widely distributed of any perennial crop and one of the top 20 most productive crops in the world. A total of 80.8 million tons of apples are produced annually worldwide. The apples domestication history starts in the Tien Shan mountains of Central Asia, at least 4,000 years ago, and probably closer to 10,000. Domestication History Modern apples were domesticated from wild apples, called crabapples. The Old English word crabbe means bitter or sharp-tasting, and that certainly describes them. There were likely three main stages in the use of apples and their eventual domestication, widely separated in time: cider production, domestication and spread, and apple breeding. Crabapple seed remains likely from cider production have been found in numerous Neolithic and Bronze age sites across Eurasia. Apples were first domesticated from the crabapple Malus sieversii Roem somewhere in the Tien Shan mountains of Central Asia (most likely Kazakhstan) between 4,000–10,000 years ago. M. sieversii grows at intermediate elevations between 900–1,600 meters above sea level (3,000–5,200 feet) and is variable in growth habit, height, fruit quality, and fruit size. Domesticated Characteristics There are thousands of apple cultivars today with a wide range of fruit sizes and flavors. The small, sour crabapple was turned into large and sweet apples, as humans selected for large fruits, firm flesh texture, longer shelf life, better post-harvest disease resistance, and reduced bruising during harvest and transportation. Flavor in apples is created by a balance between sugars and acids, both of which have been altered depending on the variety. The domestic apple also has a comparatively lengthy juvenile phase (it takes 5–7 years for apples to begin producing fruit), and the fruit hangs longer on the tree. Unlike crabapples, domesticated apples are self-incompatible, that is to say, they cant self-fertilize, so if you plant the seeds from an apple the resulting tree frequently does not resemble the parent tree. Instead, apples are propagated by grafting rootstocks. The use of dwarfed apple trees as rootstocks allows for the selection and propagation of superior genotypes. Crossing into Europe Apples were spread outside of central Asia by steppe society nomads, who traveled in caravans along ancient trade routes predating the Silk Road. Wild stands along the route were created by seed germination in horse droppings. According to several sources, a 3,800-year-old cuneiform tablet in Mesopotamia illustrates grapevine grafting, and it may well be that grafting technology helped to spread apples into Europe. The tablet itself has not yet been published. As the traders moved the apples outside of central Asia, the apples were crossed with local crabapples such as Malus baccata in Siberia; M. orientalis in the Caucasus, and M. sylvestris in Europe. Evidence of that westward movement from central Asia includes isolated patches of large sweet apples in the Caucasus mountains, Afghanistan, Turkey, Iran, and the Kursk region of European Russia. The earliest evidence for M. domestica in Europe is from the Sammardenchia-Cueis site in northeastern Italy. There a fruit from M. domestica was recovered from a context dated between 6570–5684 RCYBP (cited in Rottoli and Pessina listed below). A 3,000-year-old apple at Navan Fort in Ireland may also be evidence of early apple seedling imports from central Asia. Sweet apple production—grafting, cultivation, harvesting, storage, and the use of dwarf apple trees—is reported in ancient Greece by the 9th century BCE. The Romans learned about apples from the Greeks and then spread the new fruit throughout their empire. Modern Apple Breeding The last step in apple domestication took place only in the last few hundred years when apple breeding became popular. Current apple production worldwide is limited to a few dozen ornamental and edible cultivars, which are treated with high levels of chemical inputs: however, there are many thousands of named domestic apple varieties. Modern breeding practices start with the small set of cultivars and then create new varieties by selecting for a range of qualities: fruit quality (including flavor, taste, and texture), higher productivity, how well they keep over the winter, shorter growing seasons and synchronicity in blooming or fruit ripening, length of cold requirement and cold tolerance, drought tolerance, fruit tenacity, and disease resistance. Apples occupy a central position in folklore, culture, and art in several myths from many western societies (Johnny Appleseed, fairytales featuring witches and poisoned apples, and of course the stories of untrustworthy snakes). Unlike many other crops, new apple types are released and embraced by the marketplace—Zestar and Honeycrisp are a couple of new and successful varieties. In comparison, new grape cultivars are very rare and typically fail to gain new markets. Crabapples Crabapples are still important as sources of variation for apple breeding and food for wildlife and as hedges in agricultural landscapes. There are four extant crabapple species in the old world: M. sieversii in the Tien Shan forests; M. baccata in Siberia; M. orientalis in the Caucasus, and M. sylvestris in Europe. These four wild apple species are distributed across temperate zones in Europe, usually in small low-density patches. Only M. sieversii grows in large forests. Native North American crabapples include M. fusca, M. coronaria, M. angustifolia, and M. ioensis. All of the extant crabapples are edible and were likely used before the spread of cultivated apple, but compared with sweet apples, their fruit are tiny and sour. M. sylvestris fruit are between 1-3 centimeters (.25-1 inches) in diameter; M. baccata are 1 cm, M. orientalis are 2-4 cm (.5-1.5 in). Only M. sieversii, the progenitor fruit for our modern domesticate, can grow up to 8 cm (3 in): sweet apple varieties typically range less than 6 cm (2.5 in) in diameter.
