Tese de doutoramento, Educação (História da Educação), Universidade de Lisboa, Instituto de Educação, 2013 ; The present work intends to redirect and reposition several questions related to the birth of schools conceived for the blind, which happened simultaneously in several locations of the modern western world. This very same event may also by related with the global tendency for the school to become an institutional process of taxonomical classification and establishment of a self-control economy over the citizens being taught and socially captured, as well as with the discourses of desire of those same citizens, concerning their own integration in a space of individual power determination and development. By working with documents from three different case studies, coming from diverse political, geographical and social situations (the Institut National des Jeunes Aveugles in Paris, the Royal National Institute for the Blind in the United Kingdom and the Istituto per I Poveri Ciechi in Milan, I was able to find patterns in diversity. This empiric enrichment led me, on the footsteps of Deleuze, Derrida and Foucault, to rethink the attainability of body normalization through the normation of pedagogic and social discourses. Likewise, my question ponders the identification of common possibilities between different movements of institutional teaching, oriented for bodies with diversified sensorial input perception, paving parallel paths towards a same citizenship model. At the same time, it also awakes me to the leading of those bodies onto a provocative desire to be equal, turning each person into a participant of both a personal disciplinary web and also a labyrinth of indetermination, as powerful as self-knowledge exclusion itself. ; O presente trabalho tem como objetivo redirecionar e recolocar questões associadas ao nascimento das escolas para cegos, movimento que emergiu em diversos pontos do ocidente moderno, em associação com o movimento mais global da escola enquanto processo institucional de taxonomia ...

In March 2018, representatives of member countries of the African Union signed the African Continental Free Trade Area (AfCFTA) agreement. This agreement provides a framework for trade liberalization in goods and services and is expected to eventually cover all African countries. Using a multi-country, multi-sector general equilibrium model based on Costinot and Rodriguez-Clare (2014), we estimate the welfare effects of the AfCFTA for 45 countries in Africa. Three different model specifications-comprising both perfect competition and monopolistic competition-are used. Simulations include full elimination of import tariffs and partial but substantial reduction in non-tariff barriers (NTBs). Results reveal significant potential welfare gains from trade liberalization in Africa. As intra-regional import tariffs in the continent are already low, the bulk of these gains come from lowering NTBs. Overall gains for the continent are broadly similar under the three model specifications used, with considerable variation of potential welfare gains across countries in all model structures

African Swine Fever (ASF) has emerged as a disease of great concern to swine producers and government disease control agencies because of its severe consequences to animal health and the pig industry. Early detection of an ASF introduction is considered essential for reducing the impact of the disease. Risk-based surveillance approaches have been used as enhancements to early disease epidemic detection systems in livestock populations. Such approaches may consider the role wildlife plays in hosting and transmitting a disease. In this study, a method is presented to estimate and map the risk of introducing ASF into the domestic pig population through wild boar intermediate hosts. It makes use of data about hunted wild boar, rest areas along motorways connecting ASF affected countries to Switzerland, outdoor piggeries, and forest cover. These data were used to compute relative wild boar abundance as well as to estimate the risk of both disease introduction into the wild boar population and disease transmission to domestic pigs. The way relative wild boar abundance was calculated adds to the current state of the art by considering the effect of beech mast on hunting success and the probability of wild boar occurrence when distributing relative abundance values among individual grid cells. The risk of ASF introduction into the domestic pig population by wild boar was highest near the borders of France, Germany, and Italy. On the north side of the Alps, areas of high risk were located on the unshielded side of the main motorway crossing the Central Plateau, which acts as a barrier for wild boar. Estimating the risk of disease introduction into the domestic pig population without the intermediary of wild boar suggested that dispersing wild boar may play a key role in spreading the risk to areas remote from motorways. The results of this study can be used to focus surveillance efforts for early disease detection on high risk areas. The developed method may also inform policies to control other diseases that are ...
