La serie de televisión Dexter se caracteriza por desplegar un discurso que si bien se inscribe en un género específico, el psychokillers, se diferencia notoriamente en las formas en que es representado el mundo y la conducta de un asesino serial. El artículo intenta analizar los motivos por los cuales el sujeto espectador empatiza y simpatiza con este peculiar asesino serial, construyendo un puente entre la realidad ficcional y la realidad social actual caracterizada por la inseguridad, la incertidumbre y el trastocamiento de los valores instaurados por la modernidad sobre la idea de justicia.

Método. Analisou-se o coeficiente de mortalidade por tuberculose por 100 mil habitantes, calculado com dados do Sistema de Estatísticas Vitais da Fundação SEADE, por sexo, faixa etária e forma clínica. Para verificar a tendência dos coeficientes de mortalidade por tuberculose, foram utilizadas técnicas de regressão linear para a tuberculose como causa básica e causa associada para cada uma das variáveis de interesse. Resultados. A mortalidade por tuberculose como causa básica decresceu de forma linear de 1970 até 1993. A partir de 1994 houve uma interrupção da queda dos coeficientes de mortalidade, com exceção da faixa etária de menores de 20 anos e de 60 a 69 anos. A tuberculose como causa associada apresentou comportamento ascendente de 1985 a 1996, coincidindo com a endemia de AIDS. A partir de 1996 a mortalidade decresceu para os indivíduos com idades até 49 anos, para as demais faixas etárias a mortalidade manteve comportamento ascendente. Conclusões. A mudança na tendência de queda dos coeficientes de mortalidade como causa básica a partir de 1994 parece não estar associada à epidemia de AIDS, sugerindo problemas de operacionalização das ações de controle da tuberculose no município. A AIDS tem grande influência no comportamento da mortalidade por tuberculose como causa associada que aumentou de maneira linear de 1985 até 1995, decrescendo a partir de então coincidindo com a introdução das terapias com anti retrovirais / Abstract: Aim. To focus upon death rate due to tuberculosis as both a basic and an associated cause in the County of Campinas (State of São Paulo) during the period ranging from 1970 to the year 2000 according to gender, age and clinic form. Method. Tuberculosis death rate was analysed within the scope of each 100 thousand inhabitants. It was calculated according to data taken from the Vital Statistics System of the SEADE Foundation [Fundação SEADE] in conformity with gender, age and clinic form. The tuberculosis death rate indicators verification was accomplished by means of linear regression techniques in relation to tuberculosis as a basic cause and as an associated cause according to each of the variables concerned. Results. The death rate by tuberculosis as a basic cause decreased linearly from 1970 up to the 1993. From 1994 on, there had been an interruption in the decrease of mortality rates, except for the age groups of people under 20 and the ones from 60-69 years of age. Tuberculosis as an associated cause presented an increasing index from 1985 up to 1996, which coincide with endemic AIDS. From 1996 on, mortality decreased in relation to people aging up to 49 years of age. Other age groups death rate kept on reaching higher levels. Conclusions. The fall of tuberculosis death rates concerning people under 20 years of age can be mainly assigned to the high intradermic BCG vaccine coverage levels attained in the first year of age. The change in death rate fall tendency as a basic cause from 1994 on is not associated with endemic AIDS, which suggests operationalization problems in the actions to control tuberculosis in the area. AIDS implies noticeable influence on mortality by tuberculosis as an associated cause which linearly increased in the period ranging from 1985 to 1995. It decreased thereafter, coinciding with the introduction of therapies such as the antiretroviral ones / Mestrado / Saude Coletiva / Mestre em Saude Coletiva

The aim of this thesis is to investigate of bootstrap methods (Efron, 1979), in the the performance estimation of parameter estimates in non-linear time series models, in particular SETAR models (Tong, 1993). First and higher order SETAR models in known and unknown thresholds cases are considered. To assess the performance of bootstrap methods, we first give an extensive simulation study (by using simulated normal errors), in chapters 3 and 4, to investigate large and small sample behaviours of the true sampling distributions of parameter estimates of SETAR models and how they are affected by sample size. First and higher order SETAR models in the known and unknown threshold cases are considered. An introduction to the bootstrap methods (Efron, 1979 ) is given in chapter 5. The effect of sample size on the bootstrap distributions of parameter estimates of first and higher order SETAR models in the known and unknown threshold cases ( for given order, delay and number of thresholds ) are also investigated in this chapter, via simulation and by using the same models used in the simulated normal errors 'true distribution' case ( chapters 3 & 4). The results are compared with simulated normal case in order to assess the bootstrap results. Tong and Lim (1980) method is used for fitting SETAR models to bootstrap samples, which is also used in the initial fit. Moreover, applications of bootstrap to celebrated data sets, namely, the logarithmically transformed lynx data covering the period (182-1934); and the sunspot numbers covering the period (1700- 1920), are attempted. The cyclical behaviours of bootstrap models are also examined. Finally, in chapter 5, an attempt is also made to study the problem of non-linear properties of the skeleton of a non-linear autoregressive process (Jones, 1976) via simulation and we study in particular a limit cycle behaviour.

Causal analysis is a significant role-playing field in the applied sciences such as statistics, econometrics, and technometrics. Particularly, probability-raising models have warranted significant research interest. Most of the discussions in this area are philosophical in nature. Contemporarily, the econometric causality theory, developed by C.J.W. Granger, is popular in practical, time series causal applications. While this type of causality technique has many strong features, it has serious limitations. The processes studied, in particular, should be stationary and causal relationships are restricted to be linear. However, we cannot classify regime-switching processes as linear and stationary. I.J. Good proposed a probabilistic, event-type explication of causality that circumvents some of the limitations of Granger’s methodology. This work uses the probability raising causality ideology, as postulated by Good, to propose some causal analysis methodology applicable in a stochastic, non-stationary domain. There is a proposal made for a Good’s causality test, by transforming the originally specified probabilistic causality theory from random events to a stochastic, regime-switching framework. The researcher performed methodological validation via causality simulations for a Markov, regime-switching model. The proposed test can be used to detect whether none stochastic process is causal to the observed behaviour of another, probabilistically. In particular, the regime-switch causality explication proposed herein is pivotal to the results articulated. This research also examines the power of the proposed test by using simulations, and outlines some steps that one may take in using the test in a practical setting.

The purpose of this thesis is to determine the spectrum of a type of integral operator called "Convolution Operator" acting on LP(0, °°) . In the special case p = 2 , we have a tool called the Mellin transform, this enables us to analyze the spectrum in more detail. A number of papers have dealt with special cases of our result, the reader is referred to the bibliography of a paper by D. W. Boyd; (to appear).

We consider the entire function [formula omitted] whose set of zeros includes the zeros of [formula omitted](s), expand it in an everywhere converging Maclauring series [formula omitted] Then we determine analytic expressions for the coefficients a[formula omitted] which will enable us to proceed with the numerical evaluation of some of these coefficients. To achieve this, we define an operator D[formula omitted] acting on a restricted class of power series and which we call the zeta operator. Using the operator D[formula omitted], we are able to express the coefficients a[formula omitted] as infinite n-dimensional integrals. Numerical values for the coefficients a₀ and a₁ are easily determined. For a₂ and a₃, we transform the multidimensional integrals into products of single integrals and obtain infinite series expressions for these coefficients. Although our method can also be used on the following coefficients, it turns out that the work involved to obtain an expression leading to a practical numerical evaluation of a₄, a₅, …,seems prohibitive at this stage. We then proceed with the numerical computation of a₂ and a₃ and we use these coefficients to calculate the sums of reciprocals of the zeros of [formula omitted](s) in the critical strip. Finally, assuming Riemann hypothesis, we calculate a few other quantities which may prove to be of interest. / Science, Faculty of / Computer Science, Department of / Graduate
