Close examination of global financial systems Essay

Close assessment of worldwide money related frameworks - Essay Example Not exclusively is the current capacity of German all inclusive banking overemphasized, it maybe never was as significant as pushed, even at its top by the turn of the century. The picture that shows up isn't consistent with the case that German all inclusive banks applied impressive force on mechanical organizations and offered a lot of subsidizing (Bongini et al, 2009, p. 76). Despite the fact that there were various cases of this, these were the exemptions to the general standard, which was for organizations to help themselves within to a great extent. Even minded investigation on the overall estimations of bank-based just as market-put together money related frameworks has centered with respect to â€Å"Germany and Japan as bank-based frameworks and the United States and the United Kingdom as market-based systems† (World Bank, 2012, p. 111). The bank-put together thought underlines with respect to the helpful capacity of banks in enacting assets, sorting great endeavors, m anaging administrators, and managing hazard. The bank-put together methodology also stresses with respect to the general restrictions of market-based frameworks. Particularly, exceptionally delicate markets quickly uncover information inside open markets, which decreases the instigations for singular investors to get data. Consequently, better market extension may obstruct promptings for grouping spearheading adventures that energize advancement. Banks, then again, reduce this misfortune as they make proceeding with joins with organizations and don't uncover information quickly inside open. Backers of the bank-based methodology too feature that fluid markets structure a preferential speculator condition. In fluid markets, financial specialists can monetarily exchange their offers, with the goal that they have more modest number of instigations to apply exhaustive corporate control. As a... In the wake of raising the primary the principle subject of the exposition, we see that it makes a couple of admirable sentiments to contend about. While the capacity of monetary frameworks is contended, the presentation of various sorts of money related frameworks is much more extraordinarily contends. Banks in Germany are primarily responsible for the development of the country, having advanced and built up its businesses. To them, more than some other gathering might be ascribed the brilliant results yet figured it out. The exposition goes further into the subject by bringing different models. Down to business concentrate on the general estimations of bank-based just as market-put together budgetary frameworks has centered with respect to â€Å"Germany and Japan as bank-based frameworks and the United States and the United Kingdom as market-based systems† (World Bank, 2012, p. 111). The paper says that hypothetically, the budgetary administrations thought is totally perfect with both the bank-based just as market-based methodologies. Afterward, we are offered bits of guidance, for example, when attempting to control the plan of a monetary framework, the examination suggests that administrative bodies ought not eagerly focus on banks and markets autonomously, but instead consider them to be fundamental segments of a co-creating framework. Taking everything into account, we see that when attempting to control the structure of a monetary framework, the examination suggests that administrative bodies ought not eagerly focus on banks and markets freely, but instead consider them to be basic parts of a co-creating framework.

Goodbye, Hope to See You Again

Goodbye, Hope to See You Again This post is for those who are moving on from this blog today, May 1st First: thank you. Its been a real pleasure getting to know you. Weve spent the last year thinking about you, getting to know you, talking to you, your parents, and more. After a ridiculously competitive admissions process, we chose you from the thousands upon thousands of super-qualified applicants, because we truly believe in you. And, in the process, we grew very attached to you, and not just for what youd bring to the MIT community, but also for the amazing persons you are. Like a wise man once said, for us, its more than a job. Its hard not to get attached. This college process, is, of course, a two-way street. You get to choose where to apply, then we (the admissions officers) choose whom to admit, but the final choice is yours which school is the best fit for you? We knew coming in that approximately one-third of all of the students we admitted would choose to enroll somewhere else. Thats a statistic. But zooming in, there are 500 individuals who find a better match, and letting go of other options can be hard on both sides. That can be emotional. To those of you who have written in with personal letters some bordering on apologies (theres nothing to apologize for!) letting us know that youre choosing another school thats a better fit for you: thank you for your letters, thank you for your friendship, and congratulations on making a great choice for yourself. This isnt the end of the road, and I hope youll feel free to keep in touch and talk about all the amazing things that happen in your life. In the end, wherever you ended up for college, you were going to be an awesome person. I truly and honestly wish you all the best for your next four years and beyond. Youve got an amazingly bright future ahead.

Dishonesty As A Vice, Is Universal And Timeless Essay

Dishonesty, as a vice, is universal and timeless; according to the Bible, the very first humans on earth committed the first sin of deception. Adam and Eve lied to God about whether they had eaten the fruit of the forbidden tree in the Garden of Eden, cementing the human race as one which feels that the burden of truth is too cumbersome to carry, and dooming humanity to a life of sin. Modern liars still carry on this legacy of deception, and rather than seeing â€Å"modern liars† as their own association, all living humans are modern liars. Regardless of whether the practice of dishonesty is daily or hourly, small â€Å"white lies† or large-scale intentional misdirection, each mortal creature contributes to the act of lying. Some of these â€Å"large-scale liars† were interviewed in the documentary entitled â€Å"(Dis)Honesty: The Truth About Lies† - people from all walks of life who share solidarity in the experience of the exposition and chastisement w hich frequently follows the act of lying. The interviewees also collectively understand the snowballing effect of lies taking on a life of their own and growing exponentially in size as they must be maintained through an ever-expanding mountain of mistruths. All those who were interviewed started with good intentions and seemingly justifiable excuses for their dishonesty, and yet have all had to face the consequences that come with lying.

Should We Continue To Play Violent Video Games? Violent video games have remained in the spotlight amidst mast shootings in the United States orchestrated by avid violent video gamers. This has raised concerns about the adverse effects these games might have on gamers.

However, by the age of twelve, I explored more complicated video games that required strategic planning with reasonable violence.

At her pastor s suggestion, she and her fiancà © filled out a questionnaire to measure the strengths and weaknesses of their relationship. 165 questions derived from John Gottman’s Four Horseman, on their personalities, backgrounds, values and aspirations. â€Å"How did you answer this question?† She asked him in the car afterward.

Nutrient References Values for Australia - Myassignmenthelp.Com

Question: Discuss about the Nutrient References Values for Australia. Answer: Introduction The purpose of this essay is to demonstrate how I would design a diet plan for a pregnant woman based on professional nutrition information. With specific reference to data provided by the Ministry of Health through its periodic publications on health and nutritional guidelines, the following is a meal plan for a woman with a six-month-old pregnancy, which will ensure that the baby grows healthily and acquires the type of nutrients from the mothers main foods daily: a) Fruit and vegetables: the mother should take fruits not less than six times a day. b) Cereals and bread: wholegrain bread and cereals should be taken at least 6 times per day. c) Milk products and milk: Low-fat milk products or milk should be taken at least three times per day. d) The woman should also take at least two meals of chicken, lean meat, eggs, legumes or nuts per day. Plenty of Fluids To ensure that the mother and the baby are in constant supply of water, she should always drink immediately upon feeling thirsty. According to MOH (2015), it is also recommended for the mother to take at least 9 cups of fluids (low-fat milk or water) on a daily basis. Similarly, while it is normal to experience weight changes during pregnancy, overweight women should consider gaining less weight while underweight women should consider gaining more (World Health Organization Diet,2017). However, it is advisable to consult a doctor before intentionally gaining or losing weight during pregnancy. Keeping Safe The riskiest part of a womans life in terms of susceptibility to infections is during pregnancy. When a woman is pregnant, they are likely to acquire foodborne diseases which may ultimately affect the child (Nutrient References Values for Australia and New Zealand, 2017). Thus, to keep her and the baby safe, she should consider: a) Keeping her hands clean before eating b) Ensure food is cooked in a clean environment c) Take boiled/clean water.

Catch 22 And A Few Good Men Essays - English-language Films

Catch 22 And A Few Good Men Catch-22 and A Few Good Men Catch-22 is a novel about the Second World War. It is set on the island of Pianosa, which is off the coast of Italy. It is set in the end of the war while the Germans are on the run and being pushed out of Italy. The book focuses on a bomb group, more specifically a squadron in which a bombardier named Yossarian is assigned to. Yossarian is very upset because all these people he doesnt even know (the Germans) are trying to kill him. The novel is very hard to understand because of the way it is written. It is helpful in books about the military to have a time-date group so you know what is going on. This book doesnt have that and is so full of flash backs and flash-forwards that it made my head spin. It wasnt poorly written but it was hard follow. It has many technical errors such as having helicopters for search and rescue while helicopters werent used in military service until the Korean War. The story is a good one but paints a picture of military life as a joke almost. Most of the servicemen in this book had no discipline and did pretty much as they pleased. Yossarian goes through the whole story trying to get out of his squadron and go home. His problem is the commander of the group keeps raising the number of missions required to fly before the rotate home. Every time he gets close the raise the number on him again. Through it all he tries all these schemes to get sent home he acts sick and tries to act crazy. When he tries to acts crazy he thinks that he has a perfect plan to get sent home since there was a rule that anyone who was crazy was unfit to serve in the rigors of combat, but the rule said they had to ask to be grounded. When he goes to get himself grounded he discovers there is a catch. Catch-22 says that anyone who asks to be grounded is not crazy because recognizing danger is the process of a rational mind and anyone with a rational mind is not crazy. That is the main story line of the book. A Few Good Men is a movie about the trial of two Marines for murder. The main characters are Lt.j.g. Dan Kaffey and Lt.Cmdr Joanne Galloway. They are both lawyers in the Judge Advocate General Corps of the Department of the Navy. They are the defense attorneys for Lance Corporal Dawson and Private First Class Downey. Dawson and Downey were charged with murdering a member of their squad, Private First Class William Santiago. The reason that they killed him was technically an accident. They were trying to haze him when something went wrong. The reason they were disciplining him was because he broke the chain of command and went outside his unit for help. In the Marine Corps that is wrong because it makes the Marines in your chain of command look like a bunch of morons. The two Marines, Dawson and Downey were ordered by their platoon commander who in turn was ordered by the battalion commander to discipline Santiago. The two Marines did not want to cut a deal for minimum jail time because the believed that they did nothing wrong they were following orders and they did not intend to kill him. The movie talks about a code that Marines follow especially Marines forward deployed on tense situation. Basically the code said that the unit and the mission come first all other things are secondary including comfort and personal safety. The Marines get through the trial and are found innocent because they were only following orders and did not intend to kill Santiago. They were found guilty of conduct unbecoming of a Marine and were dishonorably discharged from the Marine Corps. The battalion commander Colonel Jessup was set to be court martialed for ordering the Code Red (hazing) and Kaffey and Galloway look like heroes for finding out the truth and righting the wrongs. When you compare these two works you find yourself

Biography of Heinrich Hertz

Biography of Heinrich Hertz Physics students around the world are familiar with the work of Heinrich Hertz, the German physicist who proved that electromagnetic waves definitely exist. His work in electrodynamics paved the way for many  modern uses of light (also known as electromagnetic waves). The frequency unit that physicists use is named the Hertz in his honor. Fast Facts Heinrich Hertz Full Name: Heinrich Rudolf HertzBest Known For: Proof of the existence of electromagnetic waves, Hertzs principle of least curvature, and the photoelectric effect.Born: February 22, 1857 in Hamburg, GermanyDied: January 1, 1894 in  Bonn, Germany, at age 36Parents: Gustav Ferdinand Hertz and Anna Elisabeth PfefferkornSpouse: Elisabeth Doll, married 1886Children: Johanna and MathildeEducation: Physics and mechanical engineering, was a professor of physics in various institutes.Significant Contributions: Proved that electromagnetic waves propagated various distances through the air, and summarized how objects of different materials affect each other on contact. Early Life and Education Heinrich Hertz was born in Hamburg, Germany, in 1857. His parents were Gustav Ferdinand Hertz (a lawyer) and Anna Elisabeth Pfefferkorn. Although his father was born Jewish, he converted to Christianity and the children were raised as Christians. This did not stop the Nazis from dishonoring Hertz after his death, due to the taint of Jewishness, but his reputation was restored after World War II. The young Hertz was educated at the Gelehrtenschule des Johanneums in Hamburg, where he showed a deep interest in scientific subjects. He went on to study engineering in Frankfurt under such scientists as Gustav Kirchhoff and Hermann Helmholtz. Kirchhoff specialized in studies of radiation, spectroscopy, and electrical circuit theories. Helmholtz was a physicist who developed theories about vision, the perception of sound and light, and the fields of electrodynamics and thermodynamics. It is small wonder then, that the young Hertz became interested in some of the same theories and eventually did his lifes work in the fields of contact mechanics and electromagnetism. Life's Work and Discoveries After earning a Ph.D. in 1880, Hertz took up a series of professorships where he taught physics and theoretical mechanics. He married Elisabeth Doll in 1886 and they had two daughters. Hertzs doctoral dissertation focused on James Clerk Maxwells theories of electromagnetism. Maxwell worked in mathematical physics until his death in 1879 and formulated what is now known as Maxwells Equations. They describe, through mathematics, the functions of electricity and magnetism. He also predicted the existence of electromagnetic waves. Hertzs work focused on that proof, which took him several years to achieve. He constructed a simple dipole antenna with a spark gap between the elements, and he managed to produce radio waves with it. Between 1879 and 1889, he did a series of experiments that used electrical and magnetic fields to produce waves that could be measured. He established that the velocity of the waves was the same as the speed of light, and studied the characteristics of the fields he generated, measuring their magnitude, polarization, and reflections. Ultimately, his work showed that light and other waves he measured were all a form of electromagnetic radiation that could be defined by Maxwells equations. He proved through his work that electromagnetic waves can and do move through the air.   In addition, Hertz focused on a concept called the photoelectric effect, which occurs when an object with electrical charge loses that charge very quickly when it is exposed to light, in his case, ultraviolet radiation. He observed and described the effect, but never explained why it happened. That was left to Albert Einstein, who published his own work on the effect. He suggested that light (electromagnetic radiation) consists of energy carried by electromagnetic waves in little packets called quanta. Hertzs studies and Einsteins later work eventually became the basis for an important branch of physics called quantum mechanics.  Hertz and his student Phillip Lenard also worked with cathode rays, which are produced inside vacuum tubes by electrodes.   Heinrich Hertzs portrait and drawings of electrical fields that he studied appeared on a German postage stamp in 1994. Deutsche Bundespost. What Hertz Missed Interestingly, Heinrich Hertz did not think his experiments with electromagnetic radiation, particularly radio waves, had any practical value. His attention was focused solely on theoretical experiments. So, he proved that electromagnetic waves propagated through the air (and space). His work led others to experiment even further with other aspects of radio waves and electromagnetic propagation. Eventually, they stumbled across the concept of using radio waves to send signals and messages, and other inventors used them to create telegraphy, radio broadcasting, and eventually television. Without Hertzs work, however, todays use of radio, TV, satellite broadcasts, and cellular technology wouldnt exist. Nor would the science of radio astronomy, which relies heavily on his work.   Other Scientific Interests Hertzs scientific accomplishments werent limited to electromagnetism. He also did a great deal of research on the topic of contact mechanics, which is the study of solid matter objects that touch each other. The big questions in this area of study have to do with the stresses the objects produce on each other, and what role friction plays in interactions between their surfaces. This is an important field of study in mechanical engineering. Contact mechanics affect design and construction in such objects as combustion engines, gaskets, metalworks, and also objects that have electrical contact with each other.   Hertzs work in contact mechanics began in 1882 when he published a paper titled On the Contact of Elastic Solids, where he was actually working with the properties of stacked lenses. He wanted to understand how their optical properties would be affected. The concept of Hertzian stress is named for him and describes the pinpoint stresses that objects undergo as they contact each other, particularly in curved objects.   Later Life Heinrich Hertz worked on his research and lecturing until his death on January 1, 1894. His health began failing several years prior to his death, and there was some evidence he had cancer.  His final years were taken up with teaching, further research, and several operations for his condition. His final publication, a book titled  Die Prinzipien der Mechanik (The Principles of Mechanics), was sent to the printer a few weeks before his death.   Honors Hertz was honored not only by the use of his name for the fundamental period of a wavelength, but his name appears on a memorial medal and a crater on the Moon. An institute called the Heinrich-Hertz Institute for Oscillation Research was founded in 1928, known today as the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI. The scientific tradition continued with various members of his family, including his daughter Mathilde, who became a famous biologist. A nephew, Gustav Ludwig Hertz, won a Nobel prize, and other family members made significant scientific contributions in medicine and physics.   Bibliography â€Å"Heinrich Hertz and Electromagnetic Radiation.† AAAS - The Worlds Largest General Scientific Society, www.aaas.org/heinrich-hertz-and-electromagnetic-radiation. www.aaas.org/heinrich-hertz-and-electromagnetic-radiation.Molecular Expressions Microscopy Primer: Specialized Microscopy Techniques - Fluorescence Digital Image Gallery - Normal African Green Monkey Kidney Epithelial Cells (Vero), micro.magnet.fsu.edu/optics/timeline/people/hertz.html.http://www-history.mcs.st-and.ac.uk/Biographies/Hertz_Heinrich.htmlâ€Å"Heinrich Rudolf Hertz.† Cardan Biography, www-history.mcs.st-and.ac.uk/Biographies/Hertz_Heinrich.html.

Freemark Abbey Winery Case Study Example | Topics and Well Written Essays - 3750 words

Freemark Abbey Winery - Case Study Example Hence, Freemark Abbey Winery might be better off harvesting immediately before the storm and eliminating the risk of the rain spoiling the grapes. The not-so-ripe grapes could yield wine that sells for $2.85 per bottle. If Jaeger decided to harvest later and the storm did not strike, there is a high chance that the acidity of the grapes would not fall below about 0.7 percent. In this case, the resulting wines would still sell at a higher price than wine produced from the not-so-ripe grapes harvested now, regardless of what the weather condition is like. However, there is a slight chance that the acidity of the of the grapes would drop below about 0.7, in which case the resulting wine would sell at a slightly lower price of $2.50 per bottle. To make this decision, a decision tree, Michael Porter's (1997) five forces analysis, and SWOT analysis are used to aid in the decision making process. Both five forces analysis and SWOT analysis reveal that Freemark Abbey Winery should pursue a differentiation strategy. From the decision tree in Appendix 1, it can be seen that there are 3 possible decision alternatives and 7 possible outcomes. The first possible decision alternative is to harvest after the storm and sell thin wine should the storm strike and the botrytis mold not form. The second possible decision alternative is to harvest after the storm and sell the wine in bulk should the storm strike and the botrytis mold not form. The third possible decision alternative is to harvest immediately. The first decision alternative has the highest expected revenue per bottle of wine but is inconsistent with a differentiation strategy. The second decision alternative yields the next higher level of expected revenue and is consistent with a differentiation strategy. The third decision alternative yields the least revenue and at the same time is inconsistent with a differentiation strategy. However, the third decision alternative is the least risky. Prioritizing the criteria, it is felt that the revenue and differentiation criteria are more important. Hence, it is recommended that Freemark Abbey harvest the grapes later. Should the storm strike and the botrytis mold not form, it is recommended that Freemark Abbey sell the wine in bulk or the grapes directly. Both the expected value and the rollback analyses yield the same recommendation. 2. DECISION PROBLEM Should the grapes be harvested immediately or after the storm If Jaeger waited after the storm, there are some chances of a warm, light rain, which will result in the formation of botrytis mold yielding the botrytised Riesling. The quantity is 30 percent lower than the normal wine but it sells for $8 per bottle. However, a storm just before the harvest is more likely to produce rain-soaked berries, yielding a thin wine that would sell wholesale for only about $2.00 per bottle and costing Freemark Abbey Winery its reputation. It could sell the wine in bulk or sell the grapes directly to preserve its reputation but these options would bring only half as much revenue, which is the second decision problem. Hence, Freemark Abbey Winery might be better off harvesting immediately before the storm and eliminating the risk of the rain spoiling the grapes. The not-so-ripe grapes could yield wine that sells for $2.85 per bottle.

Loung's Life Within One Month after the End of Her Story - Essay Example Lying on her bed, with eyes wide open, Loung stares at the ceiling and thinks of good old days, her childhood days, before the Khmer Rouge regime destroyed it once and forever. She dreams of her visit to the noodle shop with her family and her playing hotchpotch with her siblings and friends. But these thoughts inevitably turn towards that fatal day when the bad soldiers came and took her father to the killing fields. The good memories struggle hard against the flood of bad memories that impinge incessantly on her mind and then she is left to grapple in her bed clinging to her pillow, as if, it is the only thing on earth that she could rightfully hold on to. And as she slowly closes her eyes, her mind hovers over the home she has left behind, her father, mother, brothers and sisters. It is her dreams that keep her past alive. For Loung, days in the one-bedroom apartment seems better than nights. With Meng leaving in search for work, she is left with Eang who has become more like a mother to her than a sister-in-law. Loung helps Eang with all the household activities which in reality takes hardly any time. Then they sit and talk and talk about their families and days they cherish. They look outside the window to watch the hustle bustle of the street. Unknowingly, they stop talking and get engrossed in watching people on the street and try to imagine their life. They are brought back to reality by the shrill ringing of the doorbell. It is the weekly visit by the members of the sponsor who have brought them to the United States. The man sits on the dining table, the only set of chair and table in the house, and enquires about their health. He then asks Eang to sign some papers which were needed for the admission of Loung to school. He also suggests some job options for Eang and gives some papers. As Eang clo ses the door behind him, Loung looks at Eangs face, and they hug.  

Desire to be disabled: Body Integrity Identity Disorder

Desire to be disabled: Body Integrity Identity Disorder Body Integrity Identity Disorder (BIID) is a rare phenomenon in which individuals desire to become disabled through the amputation of fully functioning limbs. BIID is described as the disparity between the individuals perception of their body and the actual form of their physical body (Bayne Levy, 2005). Other psychological disorders and classifications have been linked to BIID, including Gender Identity Disorder, Body Dysmorphic Disorder, and Hypochondriasis. The neurological origins of BIID are unknown at this time, and treatment of this condition through elective amputation is highly controversial. As a clinical audiologist, it is important to recognize symptoms of BIID in patients, as well as being aware of the possible treatment of BIID through vestibular testing. Arguments for and against elective amputation will also be discussed, as well as differential diagnoses of BIID. Audiology and BIID As a clinical audiologist, coming into contact with a patient who has Body Integrity Identity Disorder (BIID) is rare. However, the possibility does exist and it is important to understand the characteristics if one should encounter a BIID patient. The awareness of BIID in the audiology field can come into play concerning treatment of BIID, with one possible option incorporating aspects of vestibular testing. Body Integrity Identity Disorder John first took leftover prescription painkillers and numbed his left foot in ice water to reduce impending pain. He then buried his foot in dry ice for six hours to induce severe frostbite and force surgeons to operate (Adams, 2007). The previous insert from William Lee Adams article, Amputee Wannabes, describes a 33-year-old mans wish for amputation of his foot. There was nothing physically or medically wrong with this limb; John only stated that he did not feel comfortable with his own body and felt as though his foot was not a part of him. After causing severe frostbite to spread throughout his foot, Johns leg was amputated above the knee. Post-surgery, he went on to describe that the operation resolved his anxiety and allowed him to be at ease in his own body (Adams, 2007). What causes someone to desire amputation of a healthy limb? This desire was first reported by French surgeon Jean-Joseph Sue in 1785 (Lawrence, 2006). However, this delusion only began to receive public attention in the early 2000s due to the increase in documented cases. Soon thereafter, a psychiatric condition titled Body Integrity Identity Disorder (BIID), previously known as Amputee Identity Disorder (AID), became the more favorable diagnosis for these individuals. Currently, it is estimated that only a few thousand people worldwide are afflicted with BIID (Henig, 2005). BIID is described as a disparity between the individuals perception of their body and the actual form of their physical body (Bayne Levy, 2005). A common complaint of these individuals is that the limb is alien and feels as though it is not part of them. Remarkably, those with BIID are often free of psychological issues, outside of their desire for amputation. Many are of normal intelligence, have families, and hold jobs such as lawyers, professors, and doctors (Henig, 2005). So what triggers these seemingly normal individuals to desire amputation? The neurological origins of this disorder are unknown, yet those with BIID share similar backgrounds. Most are exposed to an amputee at a young age, usually before they are 4 years old, and the fascination stems from this encounter. They begin to experience discomfort with their own bodies, and the delusion is full-blown by the time they reach puberty. As the leading BIID researcher at Columbia University, Michael First believes that these individuals encounter an amputee while they are still in the developmental stage in which normal individuals come to accept the existence of their own arms and legs. He believes the sight of an amputee prevents such acceptance (Adams, 2007). Although the neurological cause of BIID is unidentified, many associations have been made between BIID and other psychoses in order to narrow down the diagnosis. Whether this disorder occurs because of a single experience during childhood, or stems from a combination of other psychological conditions, it is important to discuss other closely related diagnoses of BIID. Differential Diagnoses of BIID Some professionals, such as Michael First, have suggested that BIID may involve a similar psychological desire as is seen in Gender Identity Disorder (GID), better known as transsexualism (Lawrence, 2006). GID is a condition in which wrong embodiment is the main concern. More commonly, a male patient feels as though they are a female trapped in a males body. In both BIID and GID, dissatisfaction with ones own body occurs because their body part in question disagrees with their perceived sense of self (MÃ ¼ller, 2009). This displeasure, as well as the desire for amputation, is the commonality of BIID and GID. Similarities also exist between BIID and a condition known as Body Dysmorphic Disorder (BDD). The desired outcome of those with BDD is also amputation, but these individuals mistakenly believe that a part of their body is disease-ridden or remarkably ugly. BDD ties in closely to anorexia nervosa, being that they are both delusions based on misguided perceptions of ones own body (Bayne Levy, 2005). On the contrary, the only grounds for amputation for those with BIID revolved around the fact that the body part felt foreign, despite the individuals knowledge that the limb was perfectly healthy. Desiring a Disability Individuals who are suffering with BIID have also been associated with individuals who desire to become disabled, or truly believe they are disabled or sick when they are not. One such disorder is known as Hypochondriasis, with the term hypochondriac being used more often for these individuals. Hypochondriasis is a psychiatric disorder where an individual constantly fears that they have or, at some point, will have a serious disease, even when there is no medical proof or diagnosis (Hypochondriasis, 2002). These individuals misinterpret their physical feelings as symptoms of a serious disease, similarly to those with BIID who misinterpret their healthy body part as not being part of them. Symptoms that hypochondriacs face are also similar to those with BIID, including severe anxiety and depression. Hypochondriacs are not fabricating their symptoms, and become extremely concerned with minor problems such as excessive sweating, dizziness, and occasional tinnitus (Hypochondriasis, 2002) . Hypochondriasis can also be as socially debilitating as BIID, in that it also causes individuals to not function at work or in their daily lives. Another phenomenon associated with the desire to be disabled is known as non-organic hearing loss (NOHL). NOHL is described as responses to a hearing test indicating a deficit greater than can be explained by organic pathology (Austen Lynch, 2004). Some motives for NOHL behavior include monetary and personal gain, such as being involved in a car accident and fabricating a hearing loss as a conjunctive injury. However, not all individuals who are labeled as NOHL are malingering; some truly believe they have a hearing loss, or do not respond to the audiological testing even though their hearing sensitivity is normal. There are also those known as deaf wannabes, who, much like amputee wannabes, desire to belong to a community that is based on the disability or disorder. Deaf wannabes may have grown up in the deaf community, and although they have normal hearing sensitivity, wish to be deaf themselves. Overall, these conditions listed above may or may not be exclusive. An individual may not suffer from desired amputation based solely on the condition of BIID, BDD, or GID alone. Rather, they may suffer from a variety of combinations of these disorders, including Hypochondriasis and NOHL. With NOHL as a possible association, audiologists may be included in the group of professionals who interact and help with the treatment of these patients. That being said, the associations of these disorders and the knowledge that they are closely linked may lead to the best possible diagnosis of individuals who suffer from a desired disability. Arguments in Favor of Healthy Limb Amputation Many individuals who suffer with BIID believe that amputation is the only option. Upon learning of BIID, most people would consider it a psychotic disorder that by no means should be solved through elective amputation. However, the argument for permission of amputation by surgeons has been strongly considered. Individuals with BIID often feel desperate, and if this frustration continues it may lead to dangerous behaviors. These behaviors may include self-inflicted wounds, causing infection of these wounds, and burning a limb to injure it beyond repair in order to provoke amputation. Furthermore, these individuals may go as far as carrying out amputation on their own if a surgeon will not do it. Between 1997 and 1999, elective amputations were allowed in the United Kingdom in order to avoid these hazardous behaviors of individuals with BIID. However, such operations were quickly banned after they caught the attention of the public (Sorene et al., 2006). In order to minimize the harm t hat these individuals may inflict on themselves, amputation of healthy limbs by competent surgeons may be a viable option. Another argument for the amputation of healthy limbs would be that an individual has the right to alter ones body in the pursuit of acceptance and happiness (Jotkowitz Zivotofsky, 2009). Similar to those who undergo cosmetic surgery, as well as those who have had surgery due to Gender Identity Disorder, individuals with BIID are unsatisfied with their physical appearance and desire a change. Although both cosmetic surgery and GID surgery also encounter many arguments against altering ones appearance or gender, they are nationally recognized as an accepted medical practice. If these types of surgery are allowed to improve ones body image, then elective amputations may not be far-removed from these common practices. A final argument for the amputation of healthy limbs is the possible therapeutic effects that may occur post-surgery. Bayne and Levy (2005) describe this argument in four stages: (1) the individual suffers because of their condition; (2) amputation is expected to provide relief from this suffering; (3) less-serious approaches and treatments will not bring about this relief; and (4) the severity of amputation is minimal compared to finding relief of this disorder. Some individuals who are afflicted with BIID have stated that their condition has interfered with their social lives (Bayne Levy, 2005), including their jobs and leisure activities. These individuals do have valid emotions and are truly suffering from an internal crisis, so regardless of the diagnosis of BIID, psychological intervention is necessary. Also, seeing as some BIID individuals go to extreme measures in order to reach liberation from their unwanted limbs, the therapeutic effects may be reason enough to allow healt hy limb amputations. Arguments against Healthy Limb Amputation Without question, the allowance of healthy limb amputations by surgeons would inevitably be met by resistant forces. Society is likely to lead these arguments with feelings of repugnance and disgust. In the case of individuals who have lost limbs from accidents or disease, the thought of amputating a fully functioning limb is appalling. Paddy Rossbach, the president of Amputation Coalition of America, stated that Its very difficult for people who have been through what they consider to be a devastating life experience to understand why anybody would want to mutilate himself in this way, (Henig, 2005). Others who suffered unwanted amputation often say that the existence of BIID diminishes what they have been going through emotionally. Desired amputation will meet public disdain, and those who have experienced unwanted amputation will undoubtedly be at the forefront. An additional argument against healthy limb amputations is the life-threatening consequences of such operations. According to MÃ ¼ller (2009), the principle of nonmaleficence states that physicians should not perform amputations without medical necessity. Such amputations often have severe consequences besides causing the individual to be disabled, including infection, phantom pains, thrombosis, paralysis, and necrosis (MÃ ¼ller, 2009). Furthermore, such operations may not be successful at bringing about the desired relief. In some cases, desire for a new amputation of a previously accepted limb may follow the first operation (Hilti Brugger, 2010). Amputation causes irreversible damage that may not heal properly, and if the operation is not justified based on life-saving measures, permission of such operations may never be accepted. Possible Treatment: Vestibular Caloric Testing? A final argument against healthy limb amputations is the possibility of vestibular caloric stimulation as a treatment option for BIID. Although the neurological cause of BIID is unknown, one speculation is the involvement of the right parietal lobe. Evidence of somatoparaphrenia, or the belief that part of ones own body is not their own, has been documented in cases of right parietal lobe stroke patients (MÃ ¼ller, 2009). Neuroscientists Vilayanur Ramachandran and Paul McGeoch suggested that the right parietal lobe may also be involved in BIID patients, with supportive evidence that most who desire amputation show a left-side preference, as well as an emotional rejection of their unwanted limb (MÃ ¼ller, 2009). The speculation that vestibular caloric stimulation (specifically left-ear cold water irrigation) may be a treatment option for BIID is based on its known temporary treatment of somatoparaphrenia. Benefits of caloric stimulation over amputation include less-expensive treatme nt, lack of side effects, and immediate results showing if the treatment is working or not (Ryan, 2009). Overall, a trial of vestibular caloric stimulation should be the first step in treatment of BIID, and a clinical audiologist would perform this type of testing. For this reason, knowledge of BIID and the expertise to deal with these types of patients is important for audiologists to understand. Although caloric testing has not been proven to relieve BIID patients of their suffering, and the effects on bodily awareness may disappear as soon as the caloric stimulation has stopped, it is a less drastic approach that has been speculated to be successful. In Conclusion The limited knowledge of BIID as a valid psychological condition, as well as causes and treatments, is a barrier to finding some sort of relief for these individuals. Whether or not elective amputation is the solution for patients with BIID, the drastic decision to remove ones limb forever should not be made until more is known regarding BIID. Regardless of the background and probable causes of this disorder, individuals are still suffering daily from the notion that a body part is not their own. Intervention is necessary for BIID patients, whether it be vestibular testing by an audiologist, or other therapeutic remedies. Physicians should perform a thorough diagnostic evaluation when encountering a patient with BIID. Prior to causing irreversible damage to that individuals body, other treatment options and therapy should be researched.

South African Apartheid Essay -- South Africa Apartheid Essays

Have you ever wondered how it would feel to be considered inferior because of your race? The people of South Africa had to endure racial inferiority during the era of apartheid. The apartheid laws the government of South Africa made led to an unequal lifestyle for the blacks and produced opposition. South Africa really began to suffer when apartheid was written into the law. Apartheid was first introduced in the 1948 election that the Afrikaner National Party won. The plan was to take the already existing segregation and expand it (Wright, 60). Apartheid was a system that segregated South Africa’s population racially and considered non-whites inferior (â€Å"History of South Africa in the apartheid era†). Apartheid was designed to make it legal for Europeans to dominate economics and politics (â€Å"History of South Africa in the apartheid era†). Apartheid consisted of a set of unequal laws that favored the whites (â€Å"History of South Africa in the apartheid era†). The Race Classification Act, which divided everyone into four race groups, whites, blacks, coloreds, and Indians were the first of many major laws (Evans, 8). Hundreds of thousands of black South Africans were forced to leave their homes and move into special reservations called â€Å"homelands† or Bantustans that were set up for them (Evans, 8). There were twenty-three million blacks and they were divided into nine tribal groups, Zulu, Xhosa, Tswana, North and South Sotho, Venda, Tsonga, Swansi, and South Ndebele, and each group were moved into a separate homeland (Evans, 8). Another major law was the Groups Area Act, which secluded the twenty-three million blacks to 14 percent of land, leaving 86 percent of the land for the 4.8 million (Evans, 9). Under apartheid laws a minority ... ...rry their pass books (â€Å"Black’s resistance to Apartheid†). â€Å"During 1980 there were 304 major incidents concerning struggle with apartheid including arrests, tear gas violence, stoning, and strikes (â€Å"Black’s resistance to Apartheid†). In 1986 violent conflict forced the government to assert a national state of emergency (Wright, 68). The Public Safety Act increased penalties such as fining, imprisonment, and whippings for protesting the law (â€Å"History of South Africa in the apartheid era†). Finally in 1990 De Klerk, president of South Africa unbanned the ANC (‘History of South Africa in the apartheid era†). In 1994 the first free multiracial elections were held and the people voted to end apartheid (â€Å"History of South Africa in the apartheid era†). Nelson Mandela was elected president (Wright, 66). The opposition to apartheid helped turn things around in South Africa.

Why is Aluminium utilised in the contemporary world?

Aluminium is used extravagantly in the contemporary world, primarily due to its unique structure and desirable properties. Further, aluminium is the most abundant metal in the earth’s crust; thus, scarcity is not a problem. It is a member of the Boron group of chemical elements, and is ‘the most widely used non-ferrous metal’ (Planet Ark, 2010). It has the symbol Al, and its atomic number is 13. It is necessary to consider the fact that ‘pure aluminium is not often used as it has poor mechanical properties. It is usually alloyed with other metals or silicon’ (Chemical Industry Education Centre, 2011). A key area in which aluminium alloys are utilised is for the construction of aircraft and rockets. Aircraft manufacturers use high-strength aluminium alloys for the construction of aircraft and rockets. This is because aluminium (the predominant element of the alloy) is able to be compounded with other metals and substances, is highly malleable, resistant to corrosion and consists of a high strength to density ratio, in comparison to other metals. ‘Aluminium is used in virtually all segments of the aircraft, missile and spacecraft industry-in airframes, engines, accessories, and tankage for liquid fuel and oxidizers’ (Davis, 2000).Further, Aluminium 7075 is an aluminium alloy that is used heavily in the construction of aircraft and rockets (The Aluminum Association, 2008). Aluminium consists of a low ionisation energy, as well as a relatively high atomic radius, in comparison to other metals. The ground state valence electron configuration of Aluminium is 3s2 3p1 (Web Elements Ltd, 2011). Consequently, Aluminium comprises of three valence electrons, which are able to be shared with other elements, or in this instance, metal atoms. In addition, as aluminium has a low ionization number, 6.0 Electron Volts (Ev), as well as moderately low ionisation energies, this implies that the valence electrons of aluminium atoms are not strongly held by the nucleus, and are thus, delocalized. Delocalized electrons are not restricted to one atom or another; they are distributed across several atoms in the solid. Thus, valence electrons can move freely out of the influence of their kernels (atomic orbit/structure minus valence electrons). Consequently, aluminium, and other metals, has free mobile electrons (Tutor Vista, 2010). In addition, the bonding in metals is often described through the â€Å"electron sea model†. Another reason as to why Aluminium is able to be compounded with other elements pertains to its electronegativity. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons (Clark, 2009). The Pauling Scale is used to measure the electronegativity of a particular element. Metal's reactivity is dependent on their electropositivity; thus, a metal with a higher value in the Pauling Scale is less reactive than another metal with a lower value in the Pauling Scale (Tutor Vista, 2010). The electronegativity of aluminium is 1.61 Pauling units (Pu) (refer to table 3), whereas the electronegativity of copper is 1.65 Pu and iron, 1.83 Pu (refer to table 3). Thus, aluminium is more reactive than copper and steel, and is able to be adeptly bonded with other elements. (Other factors are involved) Malleability is the ability of a metal to exhibit large deformation or plastic response when being subjected to compressive force (Engineers Edge, 2012). The key reason as to why Aluminium is highly malleable pertains to its polycrystalline structure. The polycrystalline structure of aluminium consists of various dislocations, or crystallographic defects. The presence and movement of these dislocations, gives rise to characteristic and desirable metallic properties, for instance, malleability (Davyson). Aluminium is highly resistant to corrosion. This is primarily because a thin visible oxide forms instantly, when the metal is exposed to the atmosphere. These substances are formed as aluminium has the electron configuration 1s22s22p63s23p1, and oxygen has the electron configuration 1s22s22p4; this means that aluminium loses 1-3 valance electrons to oxygen, yielding aluminium cations with a 3+ charge, as well as oxygen atoms with a 2- charge. This is an example of an ionic bond. In addition, when Aluminium oxide is formed, it consists of a noble gas configuration, and; therefore, is balanced as well as stable. The formation of Aluminium oxide can be represented by the following formula: 4Al(s) + 3O2(g) → 2Al2O3(s) Further, this oxide layer is one of the main reasons for aluminium’s good corrosion properties; it is self-repairing if damaged, and is stable in the general ph range 4-9 (SAPA Profiles UK Ltd, 2010). When aluminium is used for the construction of aircraft and rockets, it is often anodized to improve strength, and colour (Davis, 2000). Aluminium 7075 possesses an incredibly high strength to density ratio. The maximum/ultimate tensile strength of the alloy varies from 40000 psi to 78000 psi, depending on the grade of the temper (Alcoa, 2011). It is strong, with strength comparable to many steels (iron). The tensile strength of iron (Fe) is approximately 40,000 psi (All Metals & Forge Group, 2011). Aluminium 7075 has a density of 2.8g/cm ³; where as the density of steel is 7.87 g/cm ³, approximately 282.07% greater. The low atomic mass, 26.982 AMU, and high atomic radius of aluminium, 182pm, relate to the principal reason as to why it has a low density, in comparison to iron. Iron, on the other hand, has an atomic mass of 58.845 AMU and an atomic radius of 172pm. Aluminium consists of a face-centred cubic (fcc) crystal structure, whereas iron has a body-centred cubic structure. The atomic packing factor (APF) of a face-centred cubic crystal structure is 0.74, whilst the APF of a body-centred cubic crystal structure is 0.68. Although aluminium comprises of a more compact atomic structure, the fact that Aluminium has a higher atomic radius, as well as lower atomic mass, in comparison to that of iron; thus, having less mass in a certain space than iron, allows it to have a lower density. This pertains to the fact that density is equal to mass over volume (d=m/v). Aluminium is used extravagantly in the contemporary world, primarily due to its unique structure and desirable properties. A Key area in which aluminium is utilised is for the construction of aircraft and rockets. The reasons, as to why aluminium is used in this particular application, are apparent and abundant.
