The effect of competition on manager's compensation : evidence from a quasi-nat...
Fernandes, Ana P.; Ferreira, Priscila; Winters, L. AlanThis paper studies the effect of competition on executive compensation. We estimate the effect of increased product market competition on the performance-pay sensitivity of CEOs, and contrast it with the effect for department managers and other workers in the corporation. We use a recent reform that simplied firm entry regulation in Portugal as a quasi-natural experiment. The empirical strategy exploits the sta...
Firm entry deregulation, competition and returns to education and skill
Ferreira, Priscila; Fernandes, Ana P.; Winters, L. AlanThis paper studies the effect of firm entry deregulation on the returns to skill and education. We use matched employer-employee data for the universe of workers and firms in Portugal and exploit a comprehensive episode of entry deregulation, unique in the industrialized world, as a quasi-natural experiment to investigate how increased competition affects wages. We find that after the reform the returns to a un...
Caracterização do perfil de deposição e do diâmetro de gotas e otimização do es...
Fernandes,Ana P.; Parreira,Renata S.; Ferreira,Marcelo C.; Romani,Gustavo N.A escolha e o uso adequado de pontas de pulverização são essenciais para a correta aplicação de produtos fitossanitários, sendo, portanto, indispensável o conhecimento de suas características. Este trabalho teve o objetivo de caracterizar o perfil de distribuição e o diâmetro de gotas, oferecendo dados para otimizar o espaçamento entre bicos na barra de pulverização. Foram avaliados os perfis de distribuição da...
Apo B/Apo A-I ratio in central and peripheral arterial diseases
Lima,Luciana M.; Carvalho,Maria das Graças; Sabino,Adriano de P.; Mota,Ana P.L.; Fernandes,Ana P.; Sousa,Marinez O.BACKGROUND: The apo B/apo A-I ratio represents the balance between atherogenic particles, rich in apo B, and the antiatherogenic ones, apo A-I rich. This study investigated the association between atherosclerotic diseases in different anatomical sites and apo B/apo A-I ratio. METHODS: Lipids, lipoproteins, and apolipoproteins A-I and B were assessed in 30 subjects with coronary artery disease (CAD), 26 with isc...
High-sensitivity C-reactive protein in subjects with type 2 diabetes mellitus a...
Lima,Luciana M.; Carvalho,Maria das Graças; Soares,Anna L.; Sabino,Adriano de P.; Fernandes,Ana P.; Novelli,Bethânia A.; Sousa,Marinez O.Type 2 diabetes mellitus (DM2) and high blood pressure (HBP) may contribute to the development of cardiovascular disease, and inflammation may be an important factor in these diseases. In the present study, plasma levels of high-sensitivity C-reactive protein (hs-CRP) were measured in subjects with DM2 and/or HBP and compared to those of normal subjects. Eighty-nine subjects were analyzed for hs-CRP, including ...
Glucose-mediated Ca2+ signalling in single clonal insulin-secreting cells: evid...
Salgado, António P.; Santos, Rosa M.; Fernandes, Ana P.; Tomé, Angelo R.; Flatt, Peter R.; Rosário, Luís M.Using clonal insulin-secreting BRIN-BD11 cells, we have assessed whether the graded response of the whole cell population to glucose can be accounted for by a dose-dependent recruitment of individual cells, an amplification of the response of the recruited cells or both. Cytosolic free Ca2+ concentration ([Ca2+]i) is an established index of [beta]-cell function. We used fura-2 microfluorescence techniques to as...
