The theoretical foundation of the convex case discusses a local solution obtained by solving a convex problem and some additional assumptions. For nonconvex case we show that the algorithm have a global convergence, in which the theoretical foundations ensure that curvature condition is obtained. / Neste trabalho, apresentam-se caracterizações de soluções para Otimização Multiobjetivo Irrestrita para os casos de funções convexas e não convexas. A fundamentação teórica do caso convexo discorre sobre uma solução local, obtida através da resolução de um problema convexo e algumas hipóteses adicionais. Para o caso não convexo, mostramos que o algoritmo tem convergência global, no qual os fundamentos teóricos asseguram que a condição de curvatura é obtida

XIX, por meio de Gaetano Mosca (1858-1941) e Vilfredo Pareto (1848-1923), que encontrou sistematização suficiente para alcançar status de teoria política. Antonio Gramsci (1891-1937), nos Quaderni del Carcere estabelece importante diálogo com a teoria das elites, externando confluências e distanciamentos. Em comum com os autores elitistas possui a tradição maquiaveliana dos estudos políticos, isto é, o realismo maquiaveliano, que é responsável por algumas extraordinárias continuidades temáticas e afinidades nas formulações gerais de conceitos políticos entre estes autores. Contudo, existe uma discussão subjacente à teoria das elites, que, apesar de ser menos aparente, nem por isso é menos importante - o debate acerca da possibilidade de formulação de uma ciência das realidades políticas. Por meio deste debate o realismo maquiaveliano adquire diferentes feições. Pareto reivindica uma ciência livre de ideais fictícios, calcada na observação empírica e histórica, o que o leva a compreender a divisão entre governantes e governados como uma realidade imutável, correspondente às divisões do gênero humano. Gramsci, por outro lado, propõe a formulação de uma ciência da política capaz de apreender as ocorrências históricas em sua complexidade compreendendo a "realidade" como fenômeno/aparência dos processos gerados no interior do movimento dialético entre estrutura e superestrutura. Isto o leva a entender o problema das elites por um viés histórico-político. Com isto, Gramsci contribui para um enriquecimento do realismo maquiaveliano. Desta discussão acerca da possibilidade e natureza da ciência política, importantes questões de ordem metodológica e política são trazidas a lume e são importantes, cremos, não apenas para os debates da ciência política da primeira metade do século XX, mas também suscitam problemas contemporâneos e embates no interior da ciência política que permanecem como questões fundamentais para o aperfeiçoamento dos instrumentos teórico-metodológicos da disciplina / Abstract: Although the phenomenon of minority officers has been treated by different authors, was in Italy at the end of the century. XIX, by Gaetano Mosca (1858-1941) and Vilfredo Pareto (1848-1923), who found systematic enough to achieve status of political theory. Antonio Gramsci (1891-1937), in Quaderni del Carcere establishes important dialogue with the theory of elites, expressing confluences and differences. In common with the authors has the elitist tradition of Machiavellian political studies, ie, the Machiavellian realism, which is responsible for some remarkable continuities and thematic affinities in the formulations of general political concepts between these authors. However, there is a discussion of the theory underlying the elites, who, though less apparent, so it is not less important - debate about the possibility of formulating a science of political realities. Through this debate Machiavellian realism acquires different features. Pareto claims science fictional ideals of freedom, based on empirical observation and history, which leads him to understand the division between rulers and ruled as an immutable reality, corresponding to the divisions of mankind. Gramsci, on the other hand, proposes the development of a science of politics can grasp the historical occurrences in their complexity comprising the "reality" as a phenomenon/appearance of the processes generated within the dialectical movement between structure and superstructure. This leads him to understand the problem of elites by a historical-political bias. With this, Gramsci contributes to an enrichment of Machiavellian realism. This discussion about the possibility and nature of political science, important methodological issues and policy are brought to light and are important, we believe, not only for discussions of political science in the first half of the twentieth century, but also raise contemporary issues and conflicts within science policy issues that remain fundamental to improving the theoretical and methodological tools of the discipline / Doutorado / Ciencia Politica / Doutora em Ciência Política

How can we predict key decisions made by organizations in the presence of big data and on-demand information? In this dissertation we exploit a large repository of B2B real-time transactional data with service quality indicators and present evidence that organizational decision analytics apply both rational and boundedly-rational (i.e. behavioral) economic models. The dissertation’s findings demonstrate that both utility and heuristic models, respectively, play significant roles in predicting organizational decisions on churn, a key decision in this context. In the presence of a large data set the assumed rationality of organizations appears to provide accurate predictions in uncontrolled experiences and selected boundedly-rational decision rules appear to cause somatic states that make organizations more sensitive to past total qualities of service. This dissertation makes significant new contributions to the understanding of how organizations can effectively use big data to make key operational decisions. As a managerial implication, organizations must be alert to heuristics that might exacerbate the impact of total service pain on customer’s decision to churn.

The diploma thesis deals with the performance measurement in supply chains. Performs analysis of the supply chain of Dahlhausen CZ, s.ro. Detail is then focused on the creation of a new framework for evaluating the performance of suppliers of this company.

The facts that relative consumption concerns may give rise both to positional and environmental externalities, and that these two externalities are increasingly transboundary require us to derive an optimal commodity tax in an international framework. The corrective tax policy decided at a national level is found to fail to internalize all positional and environmental externalities. The optimal tax policy under an international cooperative framework reflects correction for both global positional and environmental externalities. In this broader framework, we also characterize the provision of pollution abatement as an additional policy instrument. The results show that relative concerns for one of the private goods do not lead to any modification of the policy rule for public abatement.

Magister Scientiae - MSc / The intention is to draw more specific connections between certain deconvolution methods and also to demonstrate the application of the statistical theory of estimation in the presence of measurement error. A parametric methodology for deconvolution when the underlying distribution is of the Pareto form is developed. Maximum likelihood estimation (MLE) of the parameters of the convolved distributions is considered. Standard errors of the estimated parameters are calculated from the inverse Fisher’s information matrix and a jackknife method. Probability-probability (P-P) plots and Kolmogorov-Smirnov (K-S) goodnessof- fit tests are used to evaluate the fit of the posited distribution. A bootstrapping method is used to calculate the critical values of the K-S test statistic, which are not available. / South Africa
