Mestrado em Contabilidade, Fiscalidade e Finanças Empresariais ; Este estudo pretende analisar a influência dos sistemas de governação das sociedades na prática de gestão de resultados, entre os anos de 2003 a 2011. Para tal utilizou-se uma amostra constituÃda por empresas portuguesas cotadas na Euronext Lisboa, foram construÃdas quatro medidas de gestão de resultados e recolhidos dados acerca da conc...
The changes taking place in low density territories underscore a process of spatial differentiation. Rural areas are being restructured, where macro trends interact with micro realities and micro trends, progressively building a highly diversified spatial mosaic. This paper intends to analyse a few spatial typologies, highlighting the diversity and heterogeneity of the prevailing perspectives and results, which...
A range of events and processes seem to be encouraging networks of interaction and cooperation, favouring processes of change in rural areas. Territorial interdependencies have multiplied, new identities are being built and processes of a renewed social appreciation for what is rural are starting to flourish. The local producer markets of the Trás-os-Montes e Alto-Douro region are starting to drive processes of...
O presente artigo apresentam-se resultados relativos ao estudo conjunto de diversos parâmetros na resistência mecânica e na capacidade de auto-limpeza de argamassas fotocatalíticas. Os resultados obtidos mostram que a fim de manter a mesma consistência em todas as argamassas se torna necessário aumentar a razão w/b com a percentagem de TiO2 o que se traduz numa redução acentuada da resistência mecânica das arga...
Cystic fibrosis (CF) is a genetic disorder associated with multispecies infections where interactions between classical and newly identified bacteria might be crucial to understanding the persistent colonisation in CF lungs. This study investigated the interactions between two emerging species, Inquilinus limosus and Dolosigranulum pigrum, and the conventional CF pathogen Pseudomonas aeruginosa by evaluating th...
Dissertação de mestrado em Engenharia de Informática ; Ad-hoc networks can be useful in many contexts because they can be spontaneously created and do not require any sort of infrastructure. They can be useful for small groups when no other network is accessible. They can also be used in wider areas as a low cost replacement for wireless infrastructure networks with multiple dedicated access points. Despite th...
Este trabalho expõe o levantamento estatístico e a caracterização clínica da leishmaniose cutânea na Beira Interior. Pretende-se, assim, tentar definir a importância que esta infecção assume neste meio e identificar os principais problemas epidemiológicos e clínicos com ela relacionados, bem como propor algumas medidas a tomar para a sua resolução. Foi efectuado um estudo descritivo tipo série de casos explorat...
Central banks have different objectives in the short and long run. Governments operate simultaneously at different timescales. Many economic processes are the result of the actions of several agents, who have different term objectives. Therefore, a macroeconomic time series is a combination of components operating on different frequencies. Several questions about economic time series are connected to the unders...
Economic agents simultaneously operate at different horizons. Many economic processes are the result of the actions of several agents with different term objectives. Therefore, economic time-series is a combination of components operating on different frequencies. Several questions about the data are connected to the understanding of the time-series behavior at different frequencies. While Fourier analysis is n...
