    The paper is devoted to determine necessary and sufficient conditions for existence of solutions to the problem infesssupxΩf(u(x)):uu0+W01,(Ω){\rm inf}{{\rm ess sup}_{x \in \Omega} f(\nabla u(x)): u \in u_0 + W^{1,\infty}_0(\Omega)} when the supremand ff is not necessarily level convex. These conditions are obtained through a comparison with the related level convex problem and are written in terms of a differential inclusion involving the boundary datum. Several conditions of convexity for the supremand ff are also investigated

    Dissertação de Mestrado Integrado em Medicina VeterináriaMyxomatous mitral valve disease is the most common cardiovascular disease reported in dogs. Although many patients may remain asymptomatic, some of them progress to left-sided congestive heart failure and develop clinical signs. Little has yet been published regarding the possible influence of the neutering status on changes secondary to myxomatous mitral valve disease. This study aims to assess a possible correlation between neutering status and myxomatous mitral valve disease. A retrospective study was conducted and included all the cases diagnosed with myxomatous mitral valve disease, consulted at the Cardiology service of the University of Liverpool. To help assess the association between neutering status and cardiac remodelling, dogs were categorized into four groups: FE (female entire), FN (female neutered), ME (male entire) and MN (male neutered). Retrospective review of echocardiographic data, signalment, and underlying diseases were performed. Echocardiographic measurements were made through offline analysis. Echocardiographic measurements were then compared between groups. Five hundred and eighty-two dogs (n = 582) were included: female entire (n = 24), female neutered (n = 235), male entire (n = 115) and male neutered (n = 208). Left ventricular internal diameter at end diastole (LVIDd), left atrial dimension to the aortic root diameter (LA:Ao) and left atrium maximal dimension to the aortic root dimension (LAmax:Ao) were significantly different between ME and MN, with ME dogs presenting higher mean values for LVIDd and higher median LA:Ao and LAmax:Ao measurements. Left ventricular internal diameter at end systole (LVIDs) was not significantly different between ME and MN. There were no significant differences between FE and FN groups. This study shows that neutering status may influence the development of myxomatous mitral valve disease in male dogs and that entire male dogs could be at higher risk of developing cardiac remodelling secondary to myxomatous mitral valve disease. On the other hand, neutering status doesn’t seem to have an influence on disease progression in female dogs.RESUMO - Estudo retrospetivo da associação entre a esterilização e alterações secundárias à doença mixomatosa da válvula mitral - A doença mixomatosa da válvula mitral é a doença cardiovascular mais prevalente em cães. Apesar da maior parte dos pacientes permanecerem assintomáticos, alguns podem progredir para insuficiência cardíaca esquerda e desenvolver sinais clínicos. Até hoje, existem poucas publicações sobre o possível efeito que a esterilização possa ter no desenvolvimento da doença mixomatosa da válvula mitral. O objetivo deste estudo é avaliar se existe de facto uma relação entre a esterilização e a doença mixomatosa da válvula mitral. Foi realizado um estudo retrospetivo que incluiu todos os casos diagnosticados com doença mixomatosa da válvula mitral consultados no serviço de Cardiologia da Universidade de Liverpool. Para avaliar a relação entre a esterilização e a presença de remodelação cardíaca, os cães foram categorizados em quatro grupos: FE (fêmeas inteiras), FN (fêmeas esterilizadas), ME (machos inteiros) e MN (machos castrados). A história pregressa e os dados ecocardiográficos dos animais foram revistos retrospetivamente e as medidas ecocardiográficas foram obtidas por medição offline. Estas medições foram depois comparadas entre os diferentes grupos. Quinhentos e oitenta e dois cães (n = 582) foram incluídos: fêmeas inteiras (n = 24), fêmeas esterilizadas (n = 235), machos inteiros (n = 115) e machos castrados (n = 208). Nos resultados obtidos, o diâmetro interno do ventrículo esquerdo no final da diástole (LVIDd), o rácio átrio esquerdo-aorta (LA:Ao) e o rácio diâmetro máximo do átrio esquerdo-aorta (LAmax:Ao) foram estatisticamente significativos entre machos inteiros e machos castrados. Os machos inteiros apresentaram não só um LVIDd médio superior, como também uma mediana de LA:Ao e LAmax:Ao superior aos machos castrados. Ao mesmo tempo, o diâmetro interno do ventrículo esquerdo no final da sístole (LVIDs) não mostrou ser estatisticamente significativo entre machos inteiros e machos castrados e nenhum dos parâmetros ecocardiográficos anteriormente referidos revelou ser estatisticamente significativo entre fêmeas inteiras e fêmeas esterilizadas. Este estudo demonstra que a esterilização poderá influenciar o desenvolvimento da doença mixomatosa da válvula mitral e que os cães machos inteiros poderão apresentar um maior risco de desenvolver remodelação cardíaca secundária a esta doença. No entanto, a esterilização não aparenta influenciar a progressão desta doença em cadelas.N/

    A case for including fiscal policies in the Eurostat Labour Market Policy database

    In the context of the growing coordination of labour market policies (LMP) implementation within the European Employment Strategy (EES), the Eurostat offers a harmonised database that intends to be a valuable instrument for international comparisons in the field. However, because its tight scope fails to include some important LMP measures, this database has been playing a small role on studies related with the EES as well on those broadly focusing on labour market and employment policies. This paper intends to address, by using meaningful LMP measures - tax credits in the UK, the prime pour l'emploi and general reductions of employers’ social contributions in France -, the importance of having a more comprehensive database, while maintaining its current structure. For that we discuss the aims and the level of targeting defined by the Eurostat and we include, under this framework, an assessment of these measures to illustrate the limits of the database. We conclude that these policies - apparently fitting the broad objectives of the EES - are explicitly targeted to the labour market, aim at improving its efficiency and undoubtedly benefit particular groups. Moreover, they have an important impact in terms of participants and expenditure involved.European Employment Strategy; Eurostat Database; Active Labour Market Policies; Tax Credits; Reductions of Social Security Contributions.

    La fine dell’eccezione atlantica e la decolonizzazione dell’Europa

    Fin dalla sua fondazione, il Portogallo venne visto, e si vide, come ciò che Eduardo Lourenço, nella sua opera, ha chiamato “insolita eccezione portoghese” (Lourenço, 1999a: 11). Un’eccezione divenuta storicamente norma, costruita prima di tutto in rapporto allo stesso corpo fisico e politico dell’Iberia, e che ha poi portato all’indipendenza del Regno del Portogallo, nell’eccezionale e narrativamente miracolosa, battaglia di Ourique, poi riaffermata nella non meno miracolosa battaglia di Aljubarrota; questa specie di vocazione all’eccezionalità era inscritta nella stessa geografia del paese, sottolineata già in tempi antichi da Zurara nella prima cronaca dell’espansione, la Crónica da Tomada de Ceuta.Since its foundation Portugal has been seen by others and by itself as, in the words of Eduardo Lourenço, an “uncommon Portuguese exception”. An exception that has historically become a norm firstly built upon the relationship with both the physical and political body of Iberia, leading afterwards to the independence of the Reign of Portugal. This independence was perceived as an achievement gained through the exceptional and narratively miraculous Battle of Ourique and reaffirmed then thanks to the equally miraculous Battle of Aljubarrota. This sort of vocation for 'exceptionality' was inherent in the geography of the country itself, as Zurara emphasized in ancient times in the first chronicle of its expansion: the Crónica da Tomada de Ceuta

    A partir da poesia de Ana Paula Tavares, procurarei mostrar neste artigo como a dupla premissa do poder e do conhecimento, sobre a qual se ergueu o colonialismo dos séculos XIX e XX, foi femininamente reapropriada, subvertida, desmultiplicada e antropofagizada, revelando outras identidades. Este processo inaugura assim um tempo pós-colonial de possibilidade de acesso e valorização de outros conhecimentos, de outros poderes, expressos noutras línguas, noutros sons, noutras escritas, e hoje transmitidos em língua portuguesa.Through a reading of the poetry of Ana Paula Tavares, I will argue that the power/knowledge binary, based on 19th and 20th century colonialism, has been reappropriated, subverted, multiplied and cannibalized, revealing other identities. This process thus initiates a postcolonial time of possible access and appreciation of other knowledges, other powers, expressed originally in other languages, sounds and writings, and nowadays transmitted through the Portuguese language
