Previous issue date: 2008-08-29 / The present work of research proposes to teach the fractal geometry in high school classroom, with approach in the forms the objects natural and build by the man. Despite of the utility of the fractal geometry for description of the natural objects, this geometry is a subject that has been taught poor in the last series of the high school. The objective of the work is: i. to identify as the students conceive the geometric forms of objects and processes of the nature, without previous knowledge of fractal geometry; the procedure methodological is to carry the students for to apply the Euclidian and fractal in the description of the different shape natural an build by the man. Educational software of dynamic geometry will be used to work with the Euclidean and fractal geometry. The object used will be some students the last year of the high school from a public school of the state of Pernambuco. The theory of the Kelly personal constructs were be used in the analysis of the data. / O presente trabalho propõe introduzir o conceito e propriedades da Geometria Fractal no Ensino Médio, com enfoque numa abordagem baseada nas descrições das formas dos objetos construídos pelo homem e pela natureza. A Geometria Fractal é um tema que tem sido explorado de maneira bastante superficial nas séries finais do ensino médio, apesar da sua extrema utilidade na descrição das formas construídas pela natureza. O principal objetivo do trabalho é investigar como os alunos concebem as formas geométricas dos objetos e processos da natureza. A proposta metodológica para a realização da pesquisa consistiu em utilizar objetos construídos pela natureza e pelo homem e levar os alunos a descreverem suas formas a partir da geometria euclidiana (estudada previamente) e da geometria fractal (discutida numa oficina realizada durante a pesquisa). Softwares educacionais de geometria dinâmica foram usados para trabalhar com os alunos as duas geometrias. A amostra trabalhada foi constituída de alunos de uma turma de terceiro ano do ensino médio de uma escola pública da rede oficial de ensino do Estado de Pernambuco. A teoria dos construtos pessoais de George Kelly foi usada para analisar os dados.

Client-Therapist Interaction and Perceived Therapeutic OutcomeFogle, Joseph Edwin 12 1900 (has links)
This study sought to determine the therapeutic effectiveness of client-therapist dyads in a residential treatment center for emotionally disturbed adolescents. The theories of George Kelly's personal construct psychology were utilized in assessing the dyadic relationship. The four elements investigated were organizational similarity, understanding, organizational congruency and predominant selves. The sample consisted of 140 dyads comprised of 10 adolescent boys and girls and 14 therapeutic staff of a residential treatment center in the southwest United States. Responses to Kelly's Role Construct Repertory Test were compared to four relational factors—parental/respect, identity, problem-solving, and sexual/affection—and two rating scales of client-therapist preference and ratings of therapeutic effectiveness. Contrary to expectations, as content similarity among dyads composed of clients and staff increased, there was not an increase in functional aspects of the therapy relationship. Possible mitigating factors may have been level of client disturbance and/or methodological issues relating to how organizational similarity was determined. Dyadic understanding was not found to be related to perceptions of the therapy relationship. This may be a function of adolescent of adolescent clients' need for independence and resistance to adult understanding and control. Therapy dyads with a moderate level of lateral or vertical organizational congruence were not found to be curvilinearly related to functional aspects of the therapy relationship. However, a weak linear relationship regarding client perceptions of the therapy relationship was noted on four measures. Several methodological recommendations related to the instruments used to determine therapeutic effectiveness and the means of eliciting personal constructs on the REP test.

A journey across football modelling with application to algorithmic tradingKharrat, Tarak January 2016 (has links)
In this thesis we study the problem of forecasting the final score of a football match before the game kicks off (pre-match) and show how the derived models can be used to make profit in an algorithmic trading (betting) strategy. The thesis consists of two main parts. The first part discusses the database and a new class of counting processes. The second part describes the football forecasting models. The data part discusses the details of the design, specification and data collection of a comprehensive database containing extensive information on match results and events, players' skills and attributes and betting market prices. The database was created using state of the art web-scraping, text-processing and data-mining techniques. At the time of writing, we have collected data on all games played in the five major European leagues since the 2009-2010 season and on more than 7000 players. The statistical modelling part discusses forecasting models based on a new generation of counting process with flexible inter-arrival time distributions. Several different methods for fast computation of the associated probabilities are derived and compared. The proposed algorithms are implemented in a contributed R package Countr available from the Comprehensive R Archive Network. One of these flexible count distributions, the Weibull count distribution, was used to derive our first forecasting model. Its predictive ability is compared to the models previously suggested in the literature and tested in an algorithmic trading (betting) strategy. The model developed has been shown to perform rather well compared to its competitors. Our second forecasting model uses the same statistical distribution but models the attack and defence strengths of each team at the players level rather than at a team level, as is systematically done in the literature. For this model we make heavy use of the data on the players' attributes discussed in the data part of the thesis. Not only does this model turn out to have a higher predictive power but it also allows us to answer important questions about the 'nature of the game' such as the contribution of the full-backs to the attacking efforts or where would a new team finish in the Premier League.

Comparison of the Original Operetta Arizona Lady, by Emmerich Kálmán, with its 2015 Adaptation Performed by Arizona OperaJanuary 2019 (has links)
abstract: Emmerich Kálmán (1882-1953) was a leading composer during the Silver Age of Viennese operetta. His final work, Arizona Lady (1954), premiered posthumously, on Bavarian Radio, January 1, 1954. The stage premiere followed on February 14, 1954, at the Stadttheater in Bern, Switzerland. It is his only operetta that is set entirely in the United States, in Tucson, Arizona. Arizona Opera commissioned and produced a new adaptation of Arizona Lady, which was performed in October 2015, in both Tucson, Arizona, and Phoenix, Arizona. The libretto was heavily revised, as well as translated, primarily into English with some sections in Spanish and German.
Through comparison of the original and adaptation, this study examines the artistic decisions regarding which materials, both musical and dramatic, were kept, removed, or added, as well as the rationale behind those decisions. The changes reflect differences between an Arizonan audience in 2015 and the European audience of the early 1950s. These differences include ideas of geographical identity from a native versus a foreign perspective; tolerance for nationalistic or racial stereotypes; cultural norms for gender and multiculturalism; and cultural or political agendas. Comparisons are made using the published piano/vocal score for the original version, the unpublished piano/vocal score for the adaptation, archival performance video of the Arizona Opera performance, and the compact disc recording of the 1954 radio broadcast premiere. / Dissertation/Thesis / Doctoral Dissertation Performance 2019

Previous issue date: 2014-02-17 / Pair trading is an old and well-known technique among traders. In this paper, we discuss an important element not commonly debated in Brazil: the cointegration between pairs, which would guarantee the spread stability. We run the Dickey-Fuller test to check cointegration, and then compare the results with non-cointegrated pairs. We found that the Sharpe ratio of cointegrated pairs is greater than the non-cointegrated. We also use the Ornstein-Uhlenbeck equation in order to calculate the half-life of the pairs. Again, this improves their performance. Last, we use the leverage suggested by Kelly Formula, once again improving the results.

The perceived influence of the elements of internal marketing on the brand image of staffing agencies in South AfricaBurin, Candice Natalie 08 June 2012 (has links)
M.Comm. / The primary objective of the study is to determine the influence of service quality on the perceived relationship between internal marketing and the brand image of the South African staffing brands and staffing subsidiaries of the Kelly Group. The study will further seek to determine how the different elements of internal marketing influence the brand image of employees and clients of selected staffing agencies in South Africa. The elements of internal marketing mix, namely product, price, promotion, distribution, people, processes and physical evidence will be separately observed in terms of their influence on the brand image dimensions, namely brand consistency, brand trust, brand satisfaction and brand commitment. The influence of the dimensions of service quality, namely reliability, responsiveness, assurance and empathy on the dimensions of brand image and the influence of service quality on the elements of internal marketing, will be explored in order to determine the influence of service quality on the relationship between internal marketing and brand image. A framework to manage internal marketing, service quality and brand image in an integrated manner was determined. The conclusion and findings of the study were found to support the objectives of the study, and the results of the statistical analysis were found to accept the hypotheses of the study. Various recommendations for staffing agencies were given, based on the findings of the statistical analysis. These recommendations included the need for staffing agencies to monitor service quality gaps and confirmed that the internal product was highly influential to service quality, and therefore staffing agencies need to provide a competitive internal product to employees. Internal distribution was found to be highly influential towards the responsiveness, assurance and empathy of a service, and therefore staffing agencies need to focus on creating higher levels of internal service quality and teamwork within their organisations. Physical evidence and tangibles were found to be influential regarding the assurance and empathy of service quality and the importance of a modern, open-plan staffing environment and a professional employee dress code were identified. Internal promotion was found to be influential to the responsiveness of a staffing agency’s service, and therefore the need to segment employees to determine how much and how frequently information needs to be communicated to each group of employees was mentioned. The importance of staffing agencies considering the use of new media such as social networking websites, intranets and wikis was identified as most staffing agency employees work at the clients’ premises.
