Fernando Henrique Cardoso e o pensamento político brasileiro
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Sociologia Política, Florianópolis, 2015.A construção do legado de Fernando Henrique Cardoso tem transcorrido a partir do signo de rupturas e dicotomias estruturantes, características que se articulam em torno da ideia da transição da atividade intelectual para a atividade política, num processo que reforça traços marcantes da imaginação política brasileira. Partindo da crítica dessa visão, este trabalho investiga o que o processo de formação do legado do autor como levado a cabo até aqui tem a dizer sobre os modos pelos quais se produz e se reinventa o ?pensamento político brasileiro?, ou, em outras palavras, o que sua trajetória intelectual individual representa em relação à trajetória coletiva de pensamento designada por esta expressão. Duas teses interpretativas principais são desenvolvidas ao longo deste trabalho: a primeira, de que o fio de continuidade e de unidade entre os diversos momentos da trajetória intelectual de Cardoso, negado pelas abordagens que até o presente vão dando conta da sistematização de seu legado, pode ser reconstruído e recuperado se a ênfase da análise recair na especificidade política de seus escritos, reconstrução e recuperação que, obviamente, não se furtam a considerar possíveis inconsistências, incoerências e mudanças nas crenças ao longo de sua trajetória; e a segunda, de que tal pensamento político, sem desconsiderar outras fontes genericamente rotuladas como ?universais?, estrutura-se a partir de um diálogo seletivo, sistemático e contínuo com algumas das principais matrizes de interpretação do político no país, diálogo este que, de um lado, torna possível evidenciar a existência de uma cosmovisão a atuar como ?fio condutor? para o conjunto de seu pensamento (conferindo a ele um sentido de coerência) e, de outro, entender o impacto ressignificador desse pensamento sobre tais matrizes. O trabalho está organizado em três partes: na primeira, produz-se uma reflexão teórico-metodológica do campo do pensamento político brasileiro; na segunda, discute-se a especificidade da reflexão política do autor a partir de dois momentos distintos (o do estabelecimento e o da consolidação das suas crenças políticas); e na terceira, num exercício de tentar aproximar as duas primeiras, discute-se a especificidade da inscrição do pensamento político do autor no campo do pensamento político brasileiro a partir de duas variáveis: as filiações e as recepções.Abstract : The construction of Fernando Henrique Cardoso?s legacy has been developed based on the mark of structuring ruptures and dichotomies, characteristics that are both articulated around the idea of the transition from the intellectual to the political activity, in a process that reinforces strong features of the Brazilian political imagination. Anchored in a criticism of this view, this study investigates what the process of formation of the author?s legacy developed until the present moment reveal about the forms through which the ?Brazilian political thought? is produced and reinvented, or, in other words, what his personal intellectual trajectory represents in relation to the collective thought trajectory designated by this expression. Two main interpretative theses are tested throughout this work: the first one is that the continuity and the unity between the several moments of Cardoso?s intellectual trajectory (denied by the approaches that, until the present moment, have been systematizing his legacy) can be reconstructed and recuperated if the emphasis of the analysis lies in the political specificity of his writings - assuming that both the reconstructing and the recuperation, obviously, do not fail to consider possible inconsistencies, incoherences and changes in the beliefs of the author throughout his trajectory; and second , that such political thought , without disregarding other sources generally labeled as ?universal? , is structured from a selective, systematic and continuous dialogue with some of the main forms of interpretation of the policy in the country, this dialogue , on the one hand , makes it possible to show the existence of a worldview to act as ?common thread? for all of his thought (giving him a sense of coherence), and on the other, to understand the impact of this ressignificador thinking about such matrices. The work is organized in three parts: in the first, the field of the Brazilian political thought is theoretical and methodologically questioned; in the second part, the specificity of the author?s political reflection is discussed based on two different moments (the establishment and the consolidation of his political beliefs); and, in the third part, in an attempt of approximating the two previous parts, the specificity of the insertion of the author?s political thought in the Brazilian political thought field is discussed, which is based on two variables: the filiations and the receptions
Genetic evaluation and selection in multibreed populations
No full textCrossbreeding is used widely in animal production, thus theory and methods for genetic evaluation and selection are required for multibreed populations. This study developed theory for modelling genotypic means and covariances which are required to obtain genetic evaluation by best linear unbiased prediction (BLUP) for multibreed populations. Theory and methods for genetic evaluation and selection by BLUP using the multibreed covariance theory were presented, and the effects of using this covariance theory for genetic evaluation and selection were studied. With additive inheritance, the covariance between crossbred relatives can be computed using the formula for a purebred population, provided that the variance of crossbred individuals are computed correctly. The additive variance for a crossbred individual is a function of additive variances for the pure breeds, the covariance between parents, and segregation variances. The segregation variance is the genetic variance derived from the differences in allelic frequencies between pure breeds. An efficient algorithm to compute the inverse of the additive covariance matrix was also given. With dominance inheritance, the covariance between relatives in a multibreed population is a linear function of identity coefficients, coefficients of breed origin, and 25 dispersion parameters. A recursive procedure was given to compute the necessary identity coefficients. Genetic evaluations were obtained by BLUP via Henderson's mixed model equations. Constructing these equations requires the inverse of the multibreed covariance matrix. However, an efficient method to invert this covariance matrix has not yet been developed. Thus, alternative mixed model equations were presented for obtaining genetic evaluations efficiently in two-breed and three-breed terminal crossbreeding systems. Numerical examples were used to illustrate the multibreed evaluation procedures. Multibreed covariance theory under dominance inheritance was validated by comparing a covariance matrix estimated from simulated data with the theoretical covariance matrix. Selection index theory and computer simulation were used to study the advantage of using multibreed covariance theory for genetic evaluation and selection. A significant advantage was observed when differences in allelic frequencies between the pure breeds were large and the degree of dominance was greater than or equal to one. Results from this study suggested that use of multibreed covariance theory for genetic evaluation and selection may be most useful for low heritability traits such as fertility traits.Made available in DSpace on 2011-05-07T13:35:40Z (GMT).

Methods for checking the goodness of fit of alternative nonlinear mixed models with an application in fertility traits of beef cows
No full textTwo different methods for comparing alternative mixed models describing the continuous variable underlying all-none response traits were proposed. The first may be viewed as an extension of the analysis of deviance using posterior density functions associated with alternative models, rather than likelihood functions. The major problem with the statistic generated here (referred hereafter as STAT) resides in calculating the integration constants exactly. To avoid this problem a simpler statistic (referred hereafter as STAT1), based on the joint density of the data and the unknowns, was also proposed. The second method relies on the Bayesian concept of posterior odds ratios. Several alternatives for the specification of prior distributions and the hyperparameters were suggested, and an asymptotic normal approximation of the joint posterior density was presented. Finally, guidelines for the prediction of future observations were also proposed following Bayesian procedures. Three different traits: conception to A.I sires (CAI), fertility I (FI), and conception to pasture sires (CP1) were analyzed as an illustration. These traits represented different aspects of cow fertility measured as a successful conception, i.e., calving a viable calf, to an A.I. sire or to a service sire. Using STAT and STAT1 as criteria, the simplest model explaining CAI may include as fixed factors: days postpartum, hormonal treatment, and the interaction pasture program x age of cow. With respect to FI, influential fixed factors were: type of service sire, days postpartum, age of cow, hormonal treatment, breed of service sire, and the interaction breed of service sire x type of service sire. Fixed factors affecting CP1 were: type of pasture sire, pasture program, the two-way interaction breed of pasture sire x type of pasture sire, and the three-way interaction pasture program x breed of pasture sire x breed of cow. In general, inferences with respect to the models containing interactions were not possible when STAT was used as a criterion because negative values were obtained for this statistic. However, when feasible, it seemed easier to reject null hypotheses when STAT was used.Made available in DSpace on 2011-05-07T13:36:45Z (GMT). No. of bitstreams: 2

Genetic Evaluation and Parameter Estimation Using Marker and Trait Information
No full textGenetic evaluation by BLUP using marker and trait information requires knowledge of genetic parameters, such as the recombination rate ( r) between a marker locus and a marked QTL. Maximum likelihood methods are widely used to estimate genetic parameters. This thesis presents a new approximation to the likelihood for a pedigree with loops, based on cutting all loops and extending the pedigree at the cuts. An optimum strategy to cut loops and an iterative extension technique are presented. The likelihood for a pedigree with loops is then approximated by the conditional likelihood for the entire cut-extended pedigree given the extended part. The approximation is efficient for large pedigrees with complex loops in terms of computing speed and memory requirements.Made available in DSpace on 2015-09-25T21:08:38Z (GMT). No. of bitstreams: 2

Estimation of genetic covariances between antibody response and bacterial burden
No full textFour unrelated males from a commercial broiler breeder male line were each mated to fifteen females of the same line. The offspring from four consecutive hatches received various treatments and were evaluated for resistance to Salmonella enteritidis. The standard errors for the genetic covariances indicated that the amount of data were not adequate to obtain reliable estimates of the genetic covariances. Thus, we have used likelihood theory to determine the amount of data required to obtain reliable estimates of variance and covariance components from a two-trait analysis. where both traits were not be measured on the same bird
