Determinação da prevalência de fibrilhação auricular na população portuguesa ao nível da NUTS III usando modelos hierárquicos bayesianos

A Fibrilhação Auricular é uma alteração do ritmo cardíaco designada por arritmia. Esta patologia é considerada a forma de arritmia mais frequentemente observada na prática clínica e que constitui uma importante causa de morbilidade pelo risco inerente de desenvolvimento de AVC. Em 2010 foi realizado um estudo epidemiológico na população Portuguesa com o objectivo determinar a prevalência de Fibrilhação Auricular na população portuguesa com idade igual ou superior a 40 anos, sob o acrónimo de FAMA. Os dados publicados indicaram uma estimativa de prevalência de 2,5%, com um aumento da prevalência em função da classe etária. A nível regional não foram observadas diferenças na taxa de prevalência. Estudos de mapeamento de doenças mostraram que a determinação de taxas de prevalência por região, quando o número de casos observados é relativamente baixo, apresentam sobredispersão e, consequentemente, uma falta de precisão nas estimativas obtidas através um método frequencista clássico. A utilização de modelos Bayesianos hierárquicos no mapeamento de doenças tem apresentado vantagem na estimação de valores de risco da doença comparativamente à abordagem clássica. Assim, é objectivo deste trabalho determinar a prevalência de Fibrilhação Auricular na população Portuguesa por região, ao nível da NUTS III, usando modelos hierárquicos Bayesianos. Os dados utilizados neste estudo são os dados referentes ao estudo FAMA, pós-estratificados para correcção dos ponderadores. O modelo Bayesiano proposto por Besag, York e Mollié (1991) foi usado para modelar os dados, covariando para a idade e índice de massa corporal. A revisão do desenho do estudo e o recálculo dos ponderadores foi realizado com recurso ao software R, survey, e a análise Bayesiana efectuada através do WinBugs. iii Os resultados deste estudo demonstram que o uso de modelos Bayesianos são uma melhor opção para a estimação de valores risco relativo e prevalência da doença. Contudo, a utilização de covariáveis não resultou numa melhoria considerável ao contrário do que seria esperado. Conclui-se que a Fibrilhação Auricular apresenta variações regionais significativas, a nível de NUTS III, que não devem ser desvalorizadas na determinação de políticas de saúde pública para controle da doença.

Education in Brazil: A big challenge?

Brazil is an emerging country where community school is being promoted in order to respond to the still significant gap between the poor and the rich population. This paper attempts to analyze one community school. Although other social programs whose scopes are also to enhance education have been implemented, such as the "Bolsa Familia", the impact of community schools need attention as well. Indeed, community schools must be studied due to the relevant positive attributes they can provide. Moreover, by improving the quality of education, studies show an enhancement of a higher-skilled nation and a better qualified labour force for the future. To clearly demonstrate the impacts of these communities, the treatment effect will be measured by using a matching estimator.

The establishment mode choice of German multinational enterprises in Brazil: A comparative approach

We examine the drivers behind the establishment mode choice of German multinational enterprises (MNEs) in the sectors of Automotive, Chemicals and Mechanical Engineering in Brazil for the years 1993-2013 using a novel sample of primary data obtained directly from German MNEs. Based on prevalent theories found in the literature, we test the most common hypotheses on our sample. Firms with high R&D activities and firms with prior market knowledge in Brazil in from of previous sales offices are more likely to enter Brazil by a Greenfield investment. We also show that it is the specific private ownership of the German so-called hidden champions that drive those specific SMEs to enter Brazil by Greenfield, a sneaking suspicion that has been made before. Finally, we show that the establishment mode choice between Brazil and the USA only deviates to a low extent, with German MNEs preferring to enter Brazil by Greenfield and the USA by M&A. Thereby, we provide valuable insights for future research in this field.

Potential M&A between TIM Brazil and Oi S.A: The irreversible force of Telecommunications convergence

The intrinsic forces of market aiming for telecom industry convergence has arrived to Brazil. This case presents real characters, a sequence of events and other public information that has been impacting two corporations studied in this case. TIM Brazil and Oi S.A, two top players in the Brazilian telecom industry mobile and fixed segment respectively. While a merge between the two of them looks perfect and simple in an operational perspective due to its vertical complementarity, bring to them opportunities to win over a bundle offer (multi service package) that will consolidate their market predominance. Macroeconomic and internal corporate contrasts between these companies’ environment might signal that an impulsive could have a high price to pay in the future.

Internationalization strategy of reliance to Brazil

This Work Project was focused, firstly, in an internal analysis to assess the possible competitive advantage sources of the firm and to identify the key weakness that the firm should improve before advancing with the internationalization strategy. Completed the analysis was possible to verify that the source of sustainable competitive advantage of Relance is the use of specific raw materials and that its biggest weaknesses are the lack of capacity and the excessive dependence on key employees. Overall, it was possible to conclude that the firm is in position of competing in the international markets. Secondly, due to its crucial importance, the country selection was made with a deep objective analysis, resulting with the selection of Brazil as the country with the highest market potential. Regarding the strategy to actually enter in Brazil’s market, after the study of 12 modes of entry it was possible to conclude that there is no ideal mode. However, the study performed allowed to undertake the conclusion that in order to obtain long-term optimization on the process, the adaptation, to the firm´s situation, of the Uppsala model progressive stages is the ideal. At the course of this Work Project it was inferred that the critical success factors are the choice of the distributor and the promotion of Relance as a premium brand.
