ICT in higher education in Portugal. Call computer assisted language learning
Este artÃculo pretende explorar el Aprendizaje de Lenguas Asistido por Ordenador (CALL, Computer-Assisted Language Learning) en Portugal. Para ello, se centrará en el nivel de educación superior. La escasa explotación del CALL en Portugal ha sido ampliamente estudiado en varios informes, por ejemplo, el informe encargado por la UE titulado The Impact of Information and Communications Technologies on the Teaching of Foreign Languages and on the Role of Teachers of Foreign Languages (2002: 5): "The use and employment of ICT in FLT and FLL is far from satisfactory, as ICT resources are traditionally reserved for '(computer) science' subjects, and rarely assigned to art subjects. A general lack of appropriate training of language teachers in meaningful uses of ICT tends to strengthen this trend". Este artÃculo abordará dichas necesidades centrándose en los resultados de proyectos europeos como POOLS. Analizaremos cuestiones relativas a los materiales en lÃnea que pueden utilizarse para desarrollar contenidos de clases de lengua, hacienda uso de las ventajas del e-Learning.G.I.

Simulação da brisa marÃtima na costa ocidental portuguesa
Mestrado em Meteorologia e Oceanografia FÃsicaO presente trabalho propõe estudar o comportamento da brisa marÃtima em três locais da costa ocidental portuguesa, utilizando uma simulação realizada com o modelo numérico WRF.
Foram seleccionados dois dias do mês de Agosto de 2009 para se proceder à realização da simulação. Com os resultados obtidos através da simulação foram analisados campos de temperatura, humidade relativa e vento, no sentido de comparar o comportamento nos três locais previamente seleccionados.
Foi possÃvel observar o aumento da humidade relativa e a diminuição da temperatura, consequência directa da passagem da brisa marÃtima, bem como o aumento da altura da camada limite planetária. Observou-se ainda uma zona de convergência, indicando a existência da frente de brisa.
Concluiu-se que a brisa marÃtima adquire diferentes comportamentos consoante as condições verificadas em cada local, sendo que o factor estudado neste trabalho que mais influencia esse comportamento é a topografia do terreno.
ABSTRACT: This paper proposes to study the behaviour of sea breeze in three locations at the western Portuguese coast, using a simulation with the WRF numerical model.
Two days of August 2009 were selected to proceed with the simulation. With the results obtained by the simulation fields of temperature, humidity and wind were analyzed in order to compare the behaviour in the three previously selected locations.
It was possible to observe the increase of relative humidity and a temperature decrease, a direct result of crossing the sea breeze, as well as increasing the height of the planetary boundary layer.
There was also a convergence zone, indicating the existence of the breeze front. It was concluded that the sea breeze has different behaviours depending on the conditions found at each site, and the factor studied in this work which mostly influences this behaviour is the topography
Profitability and liability of size : evidence of Portugal
Mestrado em EconomiaA presente tese apresenta um estudo do efeito do tamanho na rendibilidade das empresas recém-criadas, cobrindo um perÃodo de 8 anos, entre 2010 e 2018.
No geral, os resultados obtidos indicam que o tamanho tem um impacto positivo na rendibilidade de novas empresas. Em particular, aumentos no número de empregados têm uma relação positiva com a rendibilidade dos ativos sugerindo a existência de "liability of smalless".
Adicionalmente, a análise efetuada considera efeitos lineares e não lineares, assim como a inclusão da idade das empresas como moderador. este Os resultados obtidos são robustos a diferentes medidas de tamanho e rendibilidade.This thesis provides a comprehensive study on the effects of size on profitability for new venture firms, covering a period of 8 years, between 2010 and 2018.
Overall, the results obtained indicate that size has a positive impact on the profitability of new venture firms. In particular, increases in the number of employees will cause a positive effect on the return on assets, in all the three estimated models, thus suggesting the existence of the liability of smallness in the new firms.
Furthermore, this study accounts for both linear and non-linear effects, as well as for the inclusion of age as a moderator. Additionally, this study confirms the robustness of the results using different size and profitability measures.info:eu-repo/semantics/publishedVersio

New decision support tools for forest tactical and operational planning
Doutoramento em Engenharia Florestal e dos Recursos Florestais - Instituto Superior de AgronomiaThe economic importance of the forest resources and the Portuguese forest-based industries motivated
several studies over the last 15 years, particularly on strategic forest planning.
This thesis focuses on the forest planning processes at tactical and operational level (FTOP). These
problems relate to harvesting, transportation, storing, and delivering the forest products to the mills.
Innovative Operation Research methods and Decision Support Systems (DSS) were developed to
address some of these problems that are prevalent in Portugal.
Specifically, Study I integrates harvest scheduling, pulpwood assortment, and assignment decisions at
tactical level. The solution method was based in problem decomposition, combining heuristics and
mathematical programming algorithms.
Study II presents a solution approach based on Revenue Management principles for the reception of
Raw Materials. This operational problem avoids truck congestion during the operation of pulpwood
delivery.
Study III uses Enterprise Architecture to design a DSS for integrating the operations performed over
the pulpwood supply chain. Study IV tests this approach on a toolbox that handled the complexity of
the interactions among the agents engaged on forest planning at regional level.
Study V proposes an innovative technological framework that combines forest planning with forest
operations' control
The promotion of self-care in the elderly, psychomotor reality
Abstract: Along the aging occur several changes that influence the reduction in functionality. As a result of this process,
becomes the loss of autonomy in the elderly. The ability to self-care is aimed at maintaining life and well-being, and the
individual carries it around himself and the world that surrounds him.
This article aims to address the way in which psychomotricity is related to the promotion of self-care taking into account
the importance of self-care in the elderly and the caregiver
Posturographic Assessment in Yoga Practitioners and Non-Practitioners: Balance Benefits
[Introduction: Balance is a complex process resulting from the interaction between the following systems: sensorial (input), central nervous system (coordinator), and motor (output).The aging of the vestibular system, central nerv-ous system, and the rest of the body systems may con-tribute to balance dysfunction.]info:eu-repo/semantics/publishedVersio
