In this study, a new class of generalized distributions was developed, based on the Kummer beta distribution (NG; KOTZ, 1995), which contains as particular cases the exponentiated and beta generators of distributions. The main feature of the new family of distributions is to provide greater flexibility to the extremes of the density function and therefore, it becomes suitable for analyzing data sets with high degree of asymmetry and kurtosis. Also, two new distributions belonging to the new class of distributions, based on the Birnbaum-Saunders and generalized gamma distributions, that has as main characteristic the hazard function which assumes different forms (unimodal, bathtub shape, increase, decrease) were studied. In all studies, general mathematical properties such as ordinary and incomplete moments, generating function, mean deviations, reliability, entropies, order statistics and their moments were discussed. The estimation of parameters is approached by the method of maximum likelihood and Bayesian analysis and the observed information matrix is derived. It is also considered the likelihood ratio statistics and formal goodness-of-fit tests to compare all the proposed distributions with some of its sub-models and non-nested models. The developed results for all studies were applied to six real data sets. / Neste trabalho, foi proposta uma nova classe de distribuições generalizadas, baseada na distribuição Kummer beta (NG; KOTZ, 1995), que contém como casos particulares os geradores exponencializado e beta de distribuições. A principal característica da nova família de distribuições é fornecer grande flexibilidade para as extremidades da função densidade e portanto, ela torna-se adequada para a análise de conjuntos de dados com alto grau de assimetria e curtose. Também foram estudadas duas novas distribuições que pertencem à nova família de distribuições, baseadas nas distribuições Birnbaum-Saunders e gama generalizada, que possuem função de taxas de falhas que assumem diferentes formas (unimodal, forma de banheira, crescente e decrescente). Em todas as pesquisas, propriedades matemáticas gerais como momentos ordinários e incompletos, função geradora, desvios médio, confiabilidade, entropias, estatísticas de ordem e seus momentos foram discutidas. A estimação dos parâmetros é abordada pelo método da máxima verossimilhança e pela análise bayesiana e a matriz de informação observada foi derivada. Considerou-se, também, a estatística de razão de verossimilhanças e testes formais de qualidade de ajuste para comparar todas as distribuições propostas com alguns de seus submodelos e modelos não encaixados. Os resultados desenvolvidos foram aplicados a seis conjuntos de dados.

Nos últimos anos, diversos autores têm concentrado seus esforços na generalização de distribuições de probabilidades obtendo, dessa forma, maior flexibilidade e, consequentemente, ganho na análise de dados e na capacidade de incorporar um grande número de sub-modelos nas distribuições generalizadas.

Some properties of the new distributions are presented and the method of maximum likelihood was used to estimate the parameters of the proposed models.

Trata-se de estudo qualitativo desenvolvido por meio de análise de discurso cujo objetivo foi analisar a discursividade dos gestores em diferentes níveis de gestão sobre transferência da política do tratamento diretamente observado (TDO) no controle da tuberculose. Para isto, esta análise parte do contexto de decisão macropolítico para o contexto micropolítico tendo como cenário local o município de Ribeirão Preto-SP, considerado prioritário para o controle da doença. Foram entrevistados quatro sujeitos-gestores envolvidos com a política do TDO nas instâncias estadual, regional, municipal e no nível intermediário entre a regional e o município, mediante aceite de termo de compromisso. Os dados foram coletados no período de agosto a dezembro de 2013, as entrevistas foram audiogravadas, transcritas, respeitando-a na sua íntegra. O corpus da pesquisa foi composto por recortes, formação discursiva e marcas linguísticas, quais foram selecionados dos discursos dos sujeitos. A análise ocorreu mediante a fundamentação teórico-metodológica da Análise de Discurso (AD) de matriz francesa, que se sustenta sobre três vertentes teóricas: o Materialismo Histórico, a Linguística e a Psicanálise. Este tipo de análise não visa uma análise exaustiva horizontal ou de toda extensão do objeto de pesquisa, por entender que este não se esgota e que um discurso institui-se sempre em relação aos outros. Busca-se apoiar na exaustividade vertical com o intuito de contemplar o objetivo do trabalho e da temática abordada. Os dados foram organizados sob o eixo da temática da transferência de políticas e da temática da TB os quais apontaram para diferentes efeitos de sentido durante a transferência da política do TDO como o silenciamento, apagamento, polifonia, polissemia e contradição durante o processo de transferência desta política nos diferentes níveis de gestão, que passou gradativamente pelo processo de transferência autoritária para a transferência voluntária da maior instancia política para a menor. Destaca-se que no município este processo ocorreu de forma incompleta visto que não houve a superação do paradigma da desconcentração das ações de TB para a Atenção Primária em Saúde (APS) / This qualitative study was conducted using discourse analysis, the objective of which was analyzed the reports of different level managers regarding policy transfer of Directly Observed Treatment (DOT) in the control of tuberculosis. This analysis starts with the context of macro-political decisions in the micro-political context and the local setting was the city of Ribeirão Preto, SP, Brazil, considered a priority in the control of the disease. Four managers involved with the DOT policy at the state, regional, and city levels and another manager in the intermediate level between region and city were interviewed after signing consent forms. Data were collected from August to December 2013. The interviews were recorded, transcribed, respecting it in its entirety. The study\'s corpus was composed of excerpts, discursive formations and linguistics marks, which were selected from the participants\' reports according to the guiding question. Analysis was based on the French theoretical-methodological framework of Discourse Analysis, which in turn is grounded on three theoretical aspects: the Historical Materialism, Linguistics and Psychoanalysis. An exhaustive horizontal analysis, or an analysis that encompasses the entire extent of the research\'s object, is not intended in this type of analysis because the topic is not exhausted and discourses are always instituted in relation to others. The objective is to be supported in vertical exhaustiveness to contemplate the objective of the study and the topic under study. Data were organized under policy transfer\' and tuberculosis\' thematic axis, which indicate different effects of meanings during DOT policy transfer, such as muting, blanking, polyphony, polysemy, and contradictions during this policy transfer process at the different levels of management, which gradually moved from an authoritative transfer to a voluntary transfer, from a higher political instance to a lower one. Nonetheless, this process was not completed in the city because the paradigm decentralizing TB actions from Primary Health Care (PHC) was not overcome

In test score equating the focus is on the problem of finding the relationship between the scales of different test forms. This can be done only if data are collected in such a way that the effect of differences in ability between groups taking different test forms can be separated from the effect of differences in test form difficulty. In standard equating procedures this problem has been solved by using common examinees or common items. With common examinees, as in the equivalent groups design, the single group design, and the counterbalanced design, the examinees taking the test forms are either exactly the same, i.e., each examinee takes both test forms, or random samples from the same population. Common items (anchor items) are usually used when the samples taking the different test forms are assumed to come from different populations. The thesis consists of four papers and the main theme in three of these papers is the use of covariates, i.e., background variables correlated with the test scores, in observed score equating. We show how covariates can be used to adjust for systematic differences between samples in a non-equivalent groups design when there are no anchor items. We also show how covariates can be used to decrease the equating error in an equivalent groups design or in a non-equivalent groups design. The first paper, Paper I, is the only paper where the focus is on something else than the incorporation of covariates in equating. The paper is an introduction to test score equating, and the author's thoughts on the foundation of test score equating. There are a number of different definitions of test score equating in the literature. Some of these definitions are presented and the similarities and differences between them are discussed. An attempt is also made to clarify the connection between the definitions and the most commonly used equating functions. In Paper II a model is proposed for observed score linear equating with background variables. The idea presented in the paper is to adjust for systematic differences in ability between groups in a non-equivalent groups design by using information from background variables correlated with the observed test scores. It is assumed that conditional on the background variables the two samples can be seen as random samples from the same population. The background variables are used to explain the systematic differences in ability between the populations. The proposed model consists of a linear regression model connecting the observed scores with the background variables and a linear equating function connecting observed scores on one test forms to observed scores on the other test form. Maximum likelihood estimators of the model parameters are derived, using an assumption of normally distributed test scores, and data from two administrations of the Swedish Scholastic Assessment Test are used to illustrate the use of the model. In Paper III we use the model presented in Paper II with two different data collection designs: the non-equivalent groups design (with and without anchor items) and the equivalent groups design. Simulated data are used to examine the effect - in terms of bias, variance and mean squared error - on the estimators, of including covariates. With the equivalent groups design the results show that using covariates can increase the accuracy of the equating. With the non-equivalent groups design the results show that using an anchor test together with covariates is the most efficient way of reducing the mean squared error of the estimators. Furthermore, with no anchor test, the background variables can be used to adjust for the systematic differences between the populations and produce unbiased estimators of the equating relationship, provided that the “right” variables are used, i.e., the variables explaining those differences. In Paper IV we explore the idea of using covariates as a substitute for an anchor test with a non-equivalent groups design in the framework of Kernel Equating. Kernel Equating can be seen as a method including five different steps: presmoothing, estimation of score probabilities, continuization, equating, and calculating the standard error of equating. For each of these steps we give the theoretical results when observations on covariates are used as a substitute for scores on an anchor test. It is shown that we can use the method developed for Post-Stratification Equating in the non-equivalent groups with anchor test design, but with observations on the covariates instead of scores on an anchor test. The method is illustrated using data from the Swedish Scholastic Assessment Test.

Taking this into consideration, it was developed a descriptive and exploratory study aiming at analyzing the social representations of tuberculosis made by its patient from the Unidades de Sa?de da Fam?lia (Family Health Units a public health program) in Campina Grande City PB, in relation to the decentralization of the policies that administrate the disease. It was interviewed 34 tuberculosis patient that were being treated from 2007 to 2008. The age group of the interviewees varied from 10 to 60 years old, but most of them were between 36 and 60 years old (58,8%, n=20), some were young adult and adult (21 35 years old), with 11 (32,3%) respondents, and, less frequent, children and teenagers (11 20 years old), with 03 (8,8%) participants. Data was collected through semi-structured interview. The questions that guided the research were elaborated based on the operational recommendations of DOTS strategy; that is: access to laboratory examinations; medication guarantee; directly observed treatment. Besides that, the experiences of the patient were considered in their relation with the family and the different social groups. The analysis of the discursive material was submitted to the Analyse Lexicale par Context d un Ensemble de Segments de Texte software - ALCESTE 4.7. Data interpretation showed five categories for the social representations of the tuberculosis patient that participated in DOTS strategy: 1) the accessibility of the health assistance service; 2) the patient perspective of the disease; 3) the change in the operation of the productive life; 4) the signals and symptoms of the tuberculosis disease; 5) the rearrangement and mechanisms used to face the disease. The Central Nucleus reveals that tuberculosis is a transmissible disease that can be prevented by people through educational practices, health promotion, active search for symptomatic respiratory and control of the carriers communication; these mechanisms should be incorporated to the routine of all participants of the family health groups. The Intermediate Elements, based on quotidian life, as well as the individual experiences of the tuberculosis patient, reveals prejudiced attitude and beliefs that lead to isolation and restriction of interpersonal relationship. Peripheral Elements were constituted by themes that showed the patient feelings of indignation because of the social barriers they had to face in the Family Health Units during the treatment. These elements demonstrate a negative perspective of the representation concerning the accessibility, i.e. inadequate structure of the health service; long distance to the Health Centre, this factormakes it difficult for the patient to continue the treatment; scheduling delay; and limited service regarding other requests (doctor, dentist etc). One expects to contribute for the construction of a new perspective of the health question between the different agents who make the assistencial institutions and formation of professionals, either in central or local scope / A tuberculose, considerada uma das mais antigas doen?as que acometem a humanidade, cujos registros datam desde o ano 3900 antes de Cristo, atualmente constitui-se, no cen?rio mundial, como um grave problema de sa?de p?blica, reflexo da m? distribui??o de renda e conseq?ente precariedade das condi??es de vida, dentre outros fatores. Nesse sentido, desenvolveu-se um estudo explorat?rio e descritivo, com o objetivo de analisar as representa??es sociais da tuberculose pelos usu?rios das Unidades de Sa?de da Fam?lia do Munic?pio de Campina Grande-PB, frente ? descentraliza??o das a??es de controle da doen?a. Entrevistou-se 34 doentes de Tuberculose que realizaram tratamento no per?odo de 2007 a 2008. A faixa et?ria dos entrevistados variou entre 10 e 60 anos, com predom?nio dos 36 aos 60 (58,8%, n=20); em seguida, adulto jovem e adulto (21- 35 anos), com 11 (32,3%) respondentes e, em menor freq??ncia, a faixa correspondente a crian?as e adolescentes (11-20 anos), com 03 (8,8%) participantes. Os dados foram coletados atrav?s de entrevista semi-estruturada. As quest?es norteadoras foram elaboradas com base nas recomenda??es operacionais propostas pela Estrat?gia DOTS, a saber: acesso aos exames laboratoriais; garantia de medicamentos; tratamento diretamente observado. Al?m disso, foram consideradas as experi?ncias do usu?rio nas rela??es familiares e com os diferentes grupos sociais. A an?lise do material discursivo foi submetida ao software Analyse Lexicale par Context d un Ensemble de Segments de Texte - ALCESTE 4.7. A interpreta??o dos dados apontou cinco categorias tem?ticas em que est?o organizadas as representa??es sociais relacionadas aos doentes de tuberculose atendidos na estrat?gia DOTS: 1) A acessibilidade sobre o atendimento nos servi?os de sa?de; 2) A doen?a entendida pelos usu?rios; 3) A mudan?a de funcionamento na vida produtiva; 4) Os sinais e sintomas de estar doente com tuberculose; 5) Os rearranjos e mecanismos de enfrentamento. O N?cleo Central evidenciou a compreens?o da tuberculose como uma doen?a transmiss?vel que pode ser prevenida atrav?s de pr?ticas educativas, promo??o da sa?de, busca ativa de sintom?ticos respirat?rios, controle dos comunicantes; mecanismos que devem estar incorporados ? rotina de atividades de todos os membros das equipes de sa?de da fam?lia. Os Elementos Intermedi?rios, ancorados no cotidiano, e experi?ncias individuais dos doentes de tuberculose, apontam quest?es relacionadas a atitudes e cren?as circundadas pelo preconceito, levando ao isolamento, bem como ? restri??o dos relacionamentos interpessoais. Os Elementos Perif?ricos foram constitu?dos por temas cercados por sentimentos de indigna??o do doente de tuberculose frente ?s barreiras encontradas nas Unidades B?sicas de Sa?de da Fam?lia durante o tratamento. Estes elementos denotam um conte?do negativo da representa??o quanto ? acessibilidade, a saber: estrutura inadequada dos servi?os de sa?de; dist?ncia para o Centro de Refer?ncia (Centro de Sa?de), o que dificulta a continuidade do atendimento; demora no agendamento e resultados dos exames; limita??o dos servi?os em responder a outras demandas (m?dico, dentista, entre outras). Espera-se contribuir para a constru??o de uma nova perspectiva da quest?o sa?de entre os diferentes agentes que fazem as institui??es assistenciais e de forma??o de profissionais, seja em ?mbito central ou local.
