Advanced applied quantitative methods in finance Essay

Advanced applied quantitative methods in finance - Essay Example Financial time series have features that are represented well by models with dynamic variances. In this part, we focus at modeling the financial time series of the Italian Stock market index as well as the Spanish stock market index. We thus intend to examine the volatility in the Italian Spanish markets by understanding the change in commodity prices over a period of time. Finally we aim to present the various processes through which financial decisions are taken by aid of volatility modeling. Uses regression to provide possible estimates of the disturbance variances at each sample point and the original relation is then re-estimated by the weighted least squares procedure that corrects for the heteroskedasticity. The data is a time series data that includes 4255 daily market index prices for the Italian stock market spanning over the period 12/31/1997-22/01/2014 we also have the Spanish stock market data that includes 7122 daily market index prices spanning from 1/5/1987 to 4/22/2014 The series are characterized by random, rapid changes and are said to be volatile. The volatility seems to change over time as well. There has been upward and downward effects in volatility for the Italian market while the time series plot for Spanish market shows somehow an upward increase with slight variations (decreases) in between the years. The variations in volatility could be as a result among other factors, political factors or the international market changes. The histograms of the empirical distribution of the series are given below. For both the two market indexes, we observe that the series are leptokurtic. That is, they have lots of observations around the average and a relatively large number of observations that are far from average; for the Italian market index, the centre of the histogram has a high peak and the tails

Latin American Countries - Essay Example Native inhabitants were powerless against the superior firearm and the onslaught of foreign disease leading to their colonization. The previously free spirited populace was organized into communities and were made as labourers in gold mines and plantations. Their rights were limited and their life left to the whims of the captors. There were many excesses on the part of the victors and many sacrifices on the part of the conquered. Nevertheless, they would continue to bear this yolk as their beliefs and grudges were tempered by religious missions which instilled superstitious beliefs and damned all those who tried to break free from the system. Yet, even that could not prevent the inevitable. With the weakening of Spain and Portugal in the face of its French adversary and the rise of nationalistic sentiments, it was not long before the populace rebelled against those who have wronged them. This paper aims at investigating the fight for independence of three South American countries namely Mexico, Brazil and Chile. I am to discuss their colonial background and then highlight the similarities and difference in their fight for independence. I will also be discussing the possible reasons behind these so as to provide a more critical perspective regarding the history of the three nations. Brazil became a Portuguese colony by the early... The region soon became a major sugar, gold and diamond exporter. Brazil's road to independence started in September 1821 when Don Pedro, a Portuguese himself, defied the ruling of the Cortes in Portugal which placed the Kingdom of Brazil under direct control of Lisbon. The first confrontation involved the loyal- to-Lisbon troops and thousands of armed Brazilians. There was no bloodshed as Dom Pedro ordered the Portuguese commanding general and his soldiers to go back to Portugal. Bloodshed occurred in uprisings in other regions. Fuelled by being branded as traitors by Lisbon, Don Pedro finally declared independence in September 7, 1822 when he swore:"By my blood, by my honour, and by God: I will make Brazil free." Britain and Portugal recognized Brazilian independence by signing a treaty on August 29, 1825. (Cavaliero, 1993) Mexico's path to independence was much more violent than that of Brazil. Mexico experienced a decade long war starting with an armed conflict between the people of Mexico and Spanish colonial authorities on September 16, 1810. The Mexican War of Independence movement was led by Mexican-born Spaniards, Afro-mexicans and mestizos who sought independence from Spain. It started as an idealistic peasants' rebellion against their colonial masters, but finally ended as an unlikely alliance between conservative Spaniards not wanting to recognize the new head in their motherland and the Creoles (Spaniards born in Mexico) who instigated the cry for independence. Representatives of the Spanish crown and the head of the Mexican alliance signed on August 24, 1821 the Treaty of Crdoba which recognized Mexican independence. (Ruiz, 1992) Chile's move for independence came about when news of Napoleon's advance into Spain and the deposing of the

Health Social Care Essay Ai Identify four key pieces of Legislation and Codes of Practice relating to handling information in social care setting. 1). Data Protection Act 1998 Gives rights to individuals in respect of personal data held about them. It also seeks to protect individuals with regard to the processing of personal data. 2). Freedom of Information Act 2000 The Freedom of Information Act gives you the right to ask any public sector organisation for all the recorded information they have on any subject. Anyone can make a request for information – there are no restrictions on your age, nationality or where you live. If you ask for information about yourself, then your request will be handled under the Data Protection Act. 3). Employees Policies Procedures To make sure that all records that are kept in the office are put away in a locked secure cabinet. And when you write out the daily report sheet in the Care Plan Book, make sure that the Care Plan Book is closed and not left open. 4). Health and Social Care Act 2008 requires us to publish a code that sets out the practice we will follow in obtaining, handling, using and disclosing confidential personal information. Aii Explain how legal requirements and codes of practice affect the day to day work of a social care worker in relation to handling information. It is important to follow the codes of practice in everything you do in your day to day work. For example, I personally had a situation a while ago where my regular service user was in hospital for a couple of months, and a friend of Mr Ts approached me and asked if I could give her the key safe code so she could go into to his property and clean round and get him some shopping. I told her that I could not give her Mr Ts key safe code as it is my duty of care not to give out any information that was entrusted to me. And if I gave it to her then I would be breaking the codes of practice and my employees policies and procedures.

National Science Foundation Pre-doctoral Fellowship Essay -- Medical E

National Science Foundation Pre-doctoral Fellowship Biotin is an essential vitamin for humans; it must be included in infant formulas and in fluids for intravenous nutrition. Even though it is a necessary component of our diet, we do not yet know the mechanism by which biotin, also known as vitamin H, is synthesized in the body from dethiobiotin. The enzyme that accomplishes this conversion has been termed biotin synthase. This enzyme catalyzes the insertion of sulfur at nonactivated positions of dethiobiotin, between carbons C1 and C4, to generate biotin. This mechanism is of interest because it appears to involve uncommon chemistry and because of the commercial value of the product. Biotin is sold as a pharmaceutical and as a food and cosmetic additive. This water soluble vitamin is essential for the growth and well-being of animals and humans, and it is used in the formation of fats the utilization of carbon dioxide. Prof. Richard H. Holm's bioinorganic chemistry class sparked my interest in the understanding of enzyme mechanisms as model systems for the design of more selective drugs and better synthetic catalysts that allow us to run reactions with good yield, little waste, and inexpensively. Having worked for two years with Prof. JoAnne Stubbe on the mechanism of nucleotide reduction in E. coli by ribonucleoside diphosphate reductase, I have come to appreciate the positive effects of an understanding of this mechanism in the synthesis of more efficient drugs for the treatment of cancer and viral diseases. Increased knowledge of the biotin biosynthase mechanism should allow us to produce biotin more efficiently, and the knowledge gained from this mechanism could be applied to similar enzymes. Despite recent advan... ...should aid me in designing more successful experiments. Works Cited 1. Sanyal, I., G. Cohen, and D.H. Flint. (1994) Biochemistry 33, 3625-3631. 2. Birch, O.M., M.

Managing Cultural Diversity An Organization - 2226 Words

Managing cultural diversity workplaces are a challenge that has the potential to influence organization positively or negatively. People are an organization’s most important key of assets and knowing how to maximize their abilities is critical to success. Utilizing diversity and acknowledging, appreciating will help build the resources that business needs to be successful now and in the future. Australia has seen dramatic changes in the structure of its workplace. Now made up of women, immigrants, and minorities are increasing percentage of workplace. In addition to these workers, who speak variety different languages, approaches to work, and have varying customs, the population is also getting older, requiring people who are from†¦show more content†¦There is no accurate definition of multiculturalism . According to Koleth in Australia, Multiculturalism has served a variety of objectives over the years, including, the pursuit of social justice, appreciation of di versity and the recognition of identities, the integration of migrants, nation building, and attempts to achieve and maintain social cohesion.’ The Keating government was particularly focused on linking multiculturalism to the Australian value of ‘fair go’ (Koleth, 2010, p60). Multiculturalism has evolved as the dominant bipartisan policy approach to address Australia s cultural diversity since the early 1970s. Since that time momentous advances have been made in the workplaces. For example, anti-discrimination laws have been enacted. Government programs have become more sensitive to the needs of all clients, society has generally embraced diversity in the arts, lifestyles, and cuisine, and Australia government has begun to use cultural diversity for economic benefit. Australia government has also begun to appreciate how the existence of people from culturally diverse backgrounds in their society provides bridges to other countries and cultures in an increasingly global community. The review of literature is a key process of any research as it allows research to be placed in context. Equally, it does not only become familiar concepts, theories and arguments associated to the research topic. Particularly, this literature review comprises

How is Uranus Pronounced

The seventh planet from the Sun is a frozen ice giant of a world smothered in a heavy atmosphere. For those reasons, planetary scientists continue to study it with both ground-based and space-based telescopes. The Voyager 2 spacecraft swept past the planet in 1986, giving astronomers their first close-up look at this distant world. Historical / Getty Images However, Uranus has a problem. Or, rather, humans have a problem with its name. It has long been the butt of jokes ranging from classroom giggles to much more explicit commentary on the late-night talk shows. Why? Because it has a name that, if people say it wrong, it sounds really, really  naughty.   While school students have a lot of fun with the name, discussions about Uranus  even elicit  giggles from college students and adults at live planetarium star lectures. Its understandable, even at the same time that astronomers and teachers privately roll their eyes when they have to teach about the planet. The question is, though, is all this merriment necessary? And, how DO we say its name? One Word, Two  Uranuses It turns out that both pronunciations that people use are correct. The classic, potty-mouth version (specifically  Ã… «Ã‚ ·rÄ Ã¢â‚¬ ²Ã‚ ·nÉ™s, or you-RAY-nuss)  places the emphasis on the long A sound. Thats the one that leads to raised eyebrows, giggling and outright laughter. Its the pronunciation that most planetarium lecturers, for example, dont even want to talk about in front of an audience. Which is probably why kids still ask about it and adults still snicker when they hear it. The other pronunciation (Ã… «r†²Ã‚ ·Ã‰â„¢Ã‚ ·nÉ™s) places the emphasis on the long U while the long A sound is replaced with an uh as in YOU-ruh-nuss. As it turns out this pronunciation is the one preferred among academics. Sure, it almost sounds like Urine-uss, and that raises the eyebrows among people for whom any mention of bathroom stuff is icky. But, honestly, that second pronunciation is much better to use and is more historically accurate. The name comes from the ancient Greek name for the god of the sky. Read up on  Greek gods and mythology to learn more about the planets namesake. Uranus was considered one of the most basic  gods. He was married to the Earth mother Gaia (and, quite interestingly, he was also her son which really IS kind of racy!). They had children who became the first  Titans and were ancestors of all the other Greek gods who followed. Because Greek mythology is of interest to scholars and because Greek names are scattered throughout astronomical nomenclature, using the Greek pronunciation is more academically pleasing. Of course, its also less embarrassing. Pronouncing it YOU-ruh-nuss  stops the students from snickering. Or so people hope.   Uranus is Really Fascinating Its really too bad that people have to be so squirrelly the name of one of the more fascinating worlds in the solar system. If they look beyond the name, they would learn cool information a world that rolls around the Sun on its side and periodically points one pole or the other directly at us. That gives the planet some strange (and very long) seasons. When the Voyager 2 spacecraft rushed past, it sent back views of the planet in different wavelengths of light. Two views of Uranus from Voyager 2. The left image is a normal view, showing very little detail in the clouds. With special instruments, Voyager 2 showed us that the pole of the planet was pointing toward the Sun and that there were distinct atmospheric layers. NASA.JPL   It also checked out the strange little moons of Uranus, which all appear to be frozen, cratered, and in a few cases, have very odd-looking surfaces.   Pictures of the Uranian moon Miranda, with its unique surface features. NASA/JPL Uranus itself is classified as an ice giant world. That doesnt mean its actually made completely of ice. Its interior is a small rocky worldlet (maybe about the size of Earth) surrounded by a layer of ammonia, water, ammonia, and methane ices. Above that are the atmospheric layers, which are made mostly of hydrogen, helium, and methane gases; the topmost layer is made of clouds, and there are ice particles there, too. That qualifies as a pretty interesting world in anybodys book, regardless of what its called!   Finding Uranus Another secret about Uranus? Not so mysterious really; this world was  discovered by British astronomer and musical composer William Herschel, back in 1781. He wanted to name it after his patron, King George III. That didnt fly with astronomers in France, who claimed to have discovered it, too. So, eventually, it was named Uranus, which pleased everybody.   So, Which Uranus to Use? So which pronunciation to use? Go with whats comfortable. A sense of humor about the whole thing helps. Remember that the planet  is gassy, but those gases are mostly of hydrogen and helium, with some methane here and there. And, heres a final thought: far from being a huge joke, Uranus turns out to be a repository of important building blocks of the solar system! That ​and its position out beyond Saturn keep planetary scientists busy trying to understand its fascinating characteristics.   Edited by Carolyn Collins Petersen.
