Master of Music / Department of Music / Kurt R. Gartner / This is a report intended for musicians planning to perform any number of, or scholars seeking to enrich understanding of, the following compositions: Concerto for Marimba and Wind Ensemble by David Gillingham, XL Plus One by Alvin Etler, March from Eight Pieces for Four Timpani by Elliott Carter, 42nd Street Rondo by Wayne Siegel, and Oceanus by Steve Houghton and Wendell Yuponce. Each work is analyzed in accordance with Jan Larue's method of style analysis. For some compositions, analysis of harmony has been omitted. For all compositions, the author has added a pedagogical realm of analysis, dedicated to notable performance considerations, interpretive possibilities, and technical considerations, to Larue's organizational scheme. Therefore, the approach taken in this document can be expressed as: Sound, Harmony, Melody, Rhythm, Growth, and Performance.

One of the facets of the mobile or wireless environment is that errors quite often occur in bursts. Thus, strong codes are required to provide protection against such errors. This in turn motivates the employment of decoding algorithms which are simple to implement, yet are still able to attempt to take the dependence or memory of the channel model into account in order to give optimal decoding estimates. Furthermore, such algorithms should be able to be applied for a variety of channel models and signalling alphabets. The research presented within this thesis describes a number of algorithms which can be used with linear block codes. Given the received word, these algorithms determine the symbol which was most likely transmitted, on a symbol-by-symbol basis. Due to their relative simplicity, a collection of algorithms for memoryless channels is reported first. This is done to establish the general style and principles of the overall collection. The concept of matrix diagonalisation may or may not be applied, resulting in two different types of procedure. Ultimately, it is shown that the choice between them should be motivated by whether storage space or computational complexity has the higher priority. As with all other procedures explained herein, the derivation is first performed for a binary signalling alphabet and then extended to fields of prime order. These procedures form the paradigm for algorithms used in conjunction with finite state channel models, where errors generally occur in bursts. In such cases, the necessary information is stored in matrices rather than as scalars. Finally, by analogy with the weight polynomials of a code and its dual as characterised by the MacWilliams identities, new procedures are developed for particular types of Gilbert-Elliott channel models. Here, the calculations are derived from three parameters which profile the occurrence of errors in those models. The decoding is then carried out using polynomial evaluation rather than matrix multiplication. Complementing this theory are several examples detailing the steps required to perform the decoding, as well as a collection of simulation results demonstrating the practical value of these algorithms.

Canada's continued forgetfulness concerning slavery here, and the nation-state's attempts to record only Canada's role as a place of sanctuary for escaping African-Americans, is part of the story of absenting blackness from its history. Rinaldo Walcott The fact that people of African descent have had a presence in Canada for over four hundred years is not well known within the Canadian mainstream. The fact that slavery existed as an institution in Canada is another fact that is not well known. Within the Canadian mainstream writing of African-Canadian history, Blacks most often appear in historical narratives around the late-eighteenth and early-nineteenth centuries, as American fugitives or refugees—either as escaping slaves or British Loyalists. Through the representative writing of the "the Black refugee," Canada is often constructed as a "Promised Land," a sanctuary or safe haven for Blacks, a place of refuge and redemption that does not speak to the complex history of slavery that existed well before the American exodus. Many Black Canadian writers and scholars argue that there is a price to be paid for this kind of representation. First, the absence of people of African descent in Canadian historical narratives, prior to the coming o f the American refugees, ignores the long presence of Blacks in Canada and the contributions that Blacks have made in the development of Canada. Second, in focusing on the American Loyalists and refugee slaves, Canadian writers and historians often construct Black Canadians as a homogenous, genderless group, ignoring the diversity within Canada's Black population and, in particular, the concerns of Black women. Finally, the mainstream representation of Canada as a 'safe haven' proves problematic for any critical discussion of racism in contemporary Canadian society, for notions of "Canada the good" and "America the evil" that arose from those crossings North still penetrate the Canadian mainstream today. This autobiocritical exploration examines the representation of the haven and offers alternative readings to contemporary mainstream writings of African-Canadian history. In part one, I track the appearance of Black Canadians, over the past fifty years, from 1949 to 2001, in a survey of mainstream and scholarly texts. Using the results of this survey, which does not see the appearance of Blacks in Canada until 1977, I examine how mainstream texts might use the works of Black writers to offer more critical and complex histories of Black Canadians and, in particular, Black women. In part two, I take up an analysis of George Elliott Clarke's Beatrice Chancy. Seen as a counter-narrative to mainstream writings of African-Canadian history, Clarke's work, which takes up the subject of slavery in early-nineteenth century Nova Scotia, presents an/Other kind of Loyalist story, one with a Black woman at its centre. In this discussion I examine how Clarke's poetic work subverts the national narrative, as he speaks to the diversity within blackness and the complexities in defining racial identities.

In this purpose, this paper aimed to make, for the period between the years of 2007 and 2008, an empirical study of the brazilian stock market in the light of Technical Analysis and Behavioral Finance, as well as verifying the performance of technical index as auxiliary instrument for the decision taking. This way, the work is divided in two parts. In the first part, adopting the complementarity hypothesis of behavioral-technique approach in the process of analysis and taking of decision in the stock market, is aimed to establish a relation between Technical Analysis (Dow Theory and Elliott Waves Theory) and Behavioral Finance assumptions in the interpretation of the subprime crisis in the Brazilian stock market, through a documentary research with referring information of the years 2007 and 2008, crisis development period. The results had evidenced the utility of these theories, not only for the analysis of the subprime crisis consequences, as, also, for the examination of financial market agent s behavior in a historical perspective of larger reach. In the second part, adopting the hypothesis that the technical index are capable to assist the investors in the process of decision taking, had been refined the performances of the Exponential Moving Average, Moving Average Convergence/Divergence, Relative Force Index, Stochastic and Directional System, using as base, Brazilian s stock market data referring to the year of 2007. The research results demonstrated that the Assertiveness (A) of the purchase signals is superior to the Assertiveness (A) of the sales signals the results had demonstrated as well, the uselessness of Directional System (DS) as beeper of the market s predominant trend. / Este trabalho aprofunda a discussão no campo de estudos da Análise Técnica, alinhando suas premissas ao arcabouço teórico das Finanças Comportamentais. Neste intuito buscou-se realizar, para o período compreendido entre os anos de 2007 e 2008, um estudo empírico do mercado brasileiro de ações à luz da Análise Técnica e das Finanças Comportamentais, bem como verificar o desempenho de indicadores técnicos como instrumento auxiliar para a tomada de decisão. Desta forma, o trabalho encontra-se dividido em duas partes. Na primeira parte, adotando a hipótese de complementaridade das abordagens técnica-comportamental no processo de análise e tomada de decisão no mercado de ações, busca-se estabelecer uma relação entre os pressupostos da Análise Técnica (Teoria Dow e Teoria da Ondas de Elliott) e das Finanças Comportamentais na interpretação da crise subprime no mercado de ações brasileiro, através de uma pesquisa documental com informações referentes aos anos de 2007 e 2008, período de desenvolvimento da crise. Os resultados evidenciaram a utilidade destas teorias, não só para a análise dos reflexos da crise subprime, como, também, para o exame do comportamento dos agentes do mercado financeiro numa perspectiva histórica de maior alcance. Na segunda parte, adotando a hipótese de que os indicadores técnicos são capazes de auxiliar os investidores no processo de tomada de decisão, foram apurados os desempenhos dos indicadores Média Móvel Exponencial, Convergência/Divergência da Média Móvel, Índice de Força Relativa, Estocástico e Sistema Direcional, tomando como base dados do mercado de ações brasileiro referentes ao ano de 2007. Os resultados encontrados demonstraram que a Assertividade (A) dos sinais de compra é superior à Assertividade (A) dos sinais de venda, bem como apontaram a inutilidade do Sistema Direcional (SD) enquanto sinalizador da tendência predominante do mercado.
