Enhancing reflexivity and technology in translation learning: case study on the use of ePortfolio as a training environment

In this paper we describe a casestudy of an experiment on how reflexivity and technology can enhance learning, by using ePorfolios as a training environment to develop translation skills. Translation is today a multiskilled job and translators need to assure their clients a good performance and quality, both in language and in technology domains. In order to accomplish it, for the translator all the tasks and processes he develops appear as crucial, being pretranslation and posttranslation processes equally important as the translation itself, namely as far as autonomy, reflexive and critical skills are concerned. Finally, the need and relevance for collaborative tasks and networks amongst virtual translation communities, led us to the decision of implementing ePortfolios as a tool to develop the requested skills and extend the use of Internet in translation, namely in terminology management phases, for the completion of each task, by helping students in the management of the projects deadlines, improving their knowledge on the construction and management of translation resources and deepening their awareness about the concepts related to the development and usability of ePorfolios.

Accounting education in an action-based learning environment: lessons learned

In the context of the Bologna Declaration a change is taking place in the teaching/learning paradigm. From teaching-centered education, which emphasizes the acquisition and transmission of knowledge, we now speak of learning-centered education, which is more demanding for students. This paradigm promotes a continuum of lifelong learning, where the individual needs to be able to handle knowledge, to select what is appropriate for a particular context, to learn permanently and to understand how to learn in new and rapidly changing situations. One attempt to face these challenges has been the experience of ISCAP regarding the teaching/learning of accounting in the course Managerial Simulation. This paper describes the process of teaching, learning and assessment in an action-based learning environment. After a brief general framework that focuses on education objectives, we report the strengths and limitations of this teaching/learning tool. We conclude with some lessons from the implementation of the project.

Energy resources scheduling in competitive environment

The increasing use of distributed generation units based on renewable energy sources, the consideration of demand-side management as a distributed resource, and the operation in the scope of competitive electricity markets have caused important changes in the way that power systems are operated. The new distributed resources require an entity (player) capable to make them able to participate in electricity markets. This entity has been known as Virtual Power Player (VPP). VPPs need to consider all the business opportunities available to their resources, considering all the relevant players, the market and/or other VPPs to accomplish their goals. This paper presents a methodology that considers all these opportunities to minimize the operation costs of a VPP. The method is applied to a distribution network managed by four independent VPPs with intensive use of distributed resources.

Auction of financial transmission rights in electricity market environment

An auction model is used to increase the individual profits for market players with products they do not use. A Financial Transmission Rights Auction has the goal of trade transmission rights between Bidders and helps them raise their own profits. The ISO plays a major rule on keep the system in technical limits without interfere on the auctions offers. In some auction models the ISO decide want bids are implemented on the network, always with the objective maximize the individual profits for all bidders in the auction. This paper proposes a methodology for a Financial Transmission Rights Auction and an informatics application. The application receives offers from the purchase and sale side and considers bilateral contracts as Base Case. This goal is maximize the individual profits within the system in their technical limits. The paper includes a case study for the 30 bus IEEE test case.

Diagnóstico ambiental dos estabelecimentos de ensino orientado para a implementação de um sistema de gestão ambiental

As instituições de ensino procuram ser impulsionadoras de boas práticas ambientais demonstrando com isso o seu compromisso com o meio ambiente e com as gerações futuras. Os Sistemas de Gestão Ambiental (SGA), nomeadamente as exigências da ISO 14001:2004 podem ser uma oportunidade para as instituições gerirem correctamente todos os seus recursos, assim como eliminarem os riscos e custos desnecessários, ao mesmo tempo que reforçam os seus valores quanto à protecção do meio ambiente, prevenção da poluição, cumprimento legal e as necessidades socioeconómicas. Pretendeu-se com este estudo determinar quais os factores que condicionam a abordagem de uma política ambiental nos estabelecimentos de ensino, relacionando-as com as diferentes características das escolas com as suas abordagens ambientais, assim como determinar quais os factores que influenciam a postura ambiental das escolas. Os resultados foram recolhidos através de um inquérito por questionário, direccionado para os estabelecimentos de ensino pré-escolar, 1º, 2º, 3º ciclos e secundário da Área Metropolitana do Porto. Através da análise das respostas de 405 escolas, conclui-se que aqueles com melhores desempenhos ambientais e melhores condições para implementar um SGA são os estabelecimentos de ensino com a tipologia EB2,3/ES, públicos, pertencentes aos concelhos de Gondomar, Mais e Sto Tirso, localizados nas zonas urbanas e com edifícios escolares recentes em excelentes ou bons estados de conservação. De um modo geral todos os estabelecimentos de ensino demonstram um desempenho ambiental considerado bom e acima do considerado satisfatório para a implementação de um SGA.

Causas e consequências do empreendedorismo no concelho de Vila do Conde entre 2005 e 2011

A economia portuguesa regista nos últimos anos uma enorme “turbulência”, que foi em grande parte motivada pela constante transformação dos mercados, sobretudo dos financeiros. Torna-se então, fundamental que as empresas apostem na modernidade, na competitividade e na inovação. A atual crise económica faz “disparar” os níveis de desemprego e nesta perspetiva o empreendedorismo pode assumir um papel fundamental na compensação do mesmo. Este fenómeno pode ser visto como um elemento de desenvolvimento que contribui de uma forma positiva para o aumento da competitividade na economia, gerando riqueza e emprego. Por outro lado, pode também originar estabilidade social, uma vez, que se foca na política económica e industrial, abrangendo quer a criação de novos negócios quer o desenvolvimento de novas oportunidades de negócio em organizações já existentes. O espirito empresarial é também um grande impulsionador da inovação. O objetivo deste trabalho é analisar as causas e as consequências do empreendedorismo no Concelho de Vila do Conde entre os anos de 2005 e 2011, para se identificarem os aspetos que assumem particular relevância. Quanto à metodologia usada para estudar as causas deste fenómeno, optamos pela elaboração de um inquérito a todos os empreendedores atrás referidos, quanto à metodologia utilizada para estudar as consequências, optamos pela elaboração de um estudo económico-financeiro comparativo entre empresas de criação recentes e empresas de criação mais antiga. Com a realização deste estudo, verificamos que, no que concerne às causas, o empreendedorismo não está associado a um mecanismo de refúgio para os desempregados e ainda que a auto-realização é a principal motivação para a criação dos novos negócios. No que concerne às consequências, observamos que as empresas mais recentes apresentam pior performance económico-financeira que as mais antigas.

Estudo técnico relativo à instalação de micro eólicas em edifícios urbanos para microprodução de energia eléctrica

O Planeta Terra tem vindo a ser fustigado pelas alterações climáticas resultado da poluição ambiental provocada pelo Homem. Com o objectivo de minimizar estes efeitos deletérios, os países mais desenvolvidos estabeleceram compromissos relativamente às emissões de gases com efeito de estufa, tendo por base o Protocolo de Kyoto. A iniciativa «Renováveis na Hora» é uma das medidas previstas no plano para a política de energia e alterações climáticas, apresentado em Fevereiro de 2008, pelo Ministério da Economia e da Inovação Português. Actualmente, em Portugal, existe um mercado emergente para a microgeração, que se rege segundo a legislação aplicada recentemente, que estabelece o novo regime jurídico aplicável à produção de energia por intermédio de unidades de microprodução. Esta iniciativa levará à criação de um novo paradigma de exploração e utilização de energia. Deste modo, é fundamental avançar com alguns alertas das condições de exploração. A energia eólica é umas das fontes renováveis em que o rendimento de conversão pode atingir valores interessantes (poderá ser superior a 50%) e em determinadas regiões o seu potencial é bastante bom, nomeadamente em zonas litorais e em zonas montanhosas. Em ambiente urbano é impraticável a instalação de grandes torres eólicas, mas a micro produção baseada em pequenas turbinas eólicas é perfeitamente possível e desejável. O propósito deste trabalho é realizar um estudo de cariz técnico acerca da instalação de um mini parque eólico num edifício urbano, tendo em conta todas as condicionantes (velocidade do vento, obstáculos na zona, altura de montagem, inter-distância entre aerogeradores). Foi realizado um software que irá auxiliar a escolha dos aerogeradores e inversores para o tipo de local onde vai ser instalado o parque eólico.

Code offloading on real-time multimedia systems: a framework for handling code mobility and code offloading in a QoS aware environment

Actualmente, os smartphones e outros dispositivos móveis têm vindo a ser dotados com cada vez maior poder computacional, sendo capazes de executar um vasto conjunto de aplicações desde simples programas de para tirar notas até sofisticados programas de navegação. Porém, mesmo com a evolução do seu hardware, os actuais dispositivos móveis ainda não possuem as mesmas capacidades que os computadores de mesa ou portáteis. Uma possível solução para este problema é distribuir a aplicação, executando partes dela no dispositivo local e o resto em outros dispositivos ligados à rede. Adicionalmente, alguns tipos de aplicações como aplicações multimédia, jogos electrónicos ou aplicações de ambiente imersivos possuem requisitos em termos de Qualidade de Serviço, particularmente de tempo real. Ao longo desta tese é proposto um sistema de execução de código remota para sistemas distribuídos com restrições de tempo-real. A arquitectura proposta adapta-se a sistemas que necessitem de executar periodicamente e em paralelo mesmo conjunto de funções com garantias de tempo real, mesmo desconhecendo os tempos de execução das referidas funções. A plataforma proposta foi desenvolvida para sistemas móveis capazes de executar o Sistema Operativo Android.

Melhoria do processo produtivo da Yazaki Porto Technical Centre

No actual contexto macroeconómico, a melhoria dos processos e o aproveitamento de todas as sinergias, são factores que se tornaram ainda mais importantes e nalguns casos, condição sine qua non para a sobrevivência das próprias empresas. Cada vez mais as empresas são obrigadas a produzir mais com menos recursos, com a qualidade desejada pelos clientes e a preços competitivos. A qualidade do produto final não deve ser afectada com a desculpa da implementação de uma política da redução de custos. Pelo contrário, deve existir a preocupação de eliminar da cadeia de valor tudo o que não contribui com valor acrescentado, melhorando nalguns casos a própria qualidade do produto final. A realização deste projecto tem como objectivo, analisar e implementar, através de ferramentas relacionadas com a metodologia Lean, melhorias na produção de aplicadores de cravação numa empresa multinacional ligada ao ramo automóvel. Pretende-se um aumento da taxa de produção diária em 50%, obtida essencialmente através do balanceamento dos recursos humanos e no desenvolvimento de um sistema kanban incorporado no sector produtivo. A parte inicial do trabalho incidiu no estudo e análise do produto e respectivo processo produtivo. Posteriormente e por várias fases efectuaram-se análises aos tempos de fabrico e ao sequenciamento das operações, com vista ao conhecimento de todo o processo de montagem de modo a identificar os aspectos de melhoria. Após o registo dos pontos a eliminar e/ou a melhorar, procedeu-se a uma análise criteriosa dos dados recolhidos, efectuando-se o balanceamento dos recursos de modo a tornar eficaz a implementação do sistema kanban. Este sistema é a base da melhoria proposta para este tema de dissertação. Após implementação do sistema kanban, foi avaliado o seu desempenho e foram registadas melhorias na produção diária dos aplicadores bem como no lead time despendido no processamento dos mesmos.

Ecotoxicological aspects related to the presence of pharmaceuticals in the aquatic environment

Pharmaceuticals are biologically active and persistent substances which have been recognized as a continuing threat to environmental stability. Chronic ecotoxicity data as well as information on the current distribution levels in different environmental compartments continue to be sparse and are focused on those therapeutic classes that are more frequently prescribed and consumed. Nevertheless, they indicate the negative impact that these chemical contaminants may have on living organisms, ecosystems and ultimately, public health. This article reviews the different contamination sources as well as fate and both acute and chronic effects on non-target organisms. An extensive review of existing data in the form of tables, encompassing many therapeutic classes is presented.

Effects of home environment and center-based child care quality on children’s

This study examined the joint effects of home environment and center-based child care quality on children’s language, communication, and early literacy development, while also considering prior developmental level. Participants were 95 children (46 boys), assessed as toddlers (mean age = 26.33 months;Time 1) and preschoolers (mean age = 68.71 months; Time 2) and their families. At both times, children attended center-based child care classrooms in the metropolitan area of Porto, Portugal. Results from hierarchical linear models indicated that home environment and preschool quality, but not center-based toddler child care quality, were associated with children’s language and literacy outcomes at Time 2. Moreover, the quality of preschool classrooms moderated the association between home environment quality and children’s language and early literacy skills – but not communication skills – at Time 2, suggesting the positive cumulative effects of home environment and preschool quality. Findings further support the existence of a detrimental effect of low preschool quality on children’s language and early literacy outcomes: positive associations among home environment quality and children’s developmental outcomes were found to reduce substantially when children attended low-quality preschool classrooms.

Legal and political regulation of higher education in Portugal: an evolutionary perspective on the current policy issues and the problem of order

The higher education system in Europe is currently under stress and the debates over its reform and future are gaining momentum. Now that, for most countries, we are in a time for change, in the overall society and the whole education system, the legal and political dimensions have gained prominence, which has not been followed by a more integrative approach of the problem of order, its reform and the issue of regulation, beyond the typical static and classical cost-benefit analyses. The two classical approaches for studying (and for designing the policy measures of) the problem of the reform of the higher education system - the cost-benefit analysis and the legal scholarship description - have to be integrated. This is the argument of our paper that the very integration of economic and legal approaches, what Warren Samuels called the legal-economic nexus, is meaningful and necessary, especially if we want to address the problem of order (as formulated by Joseph Spengler) and the overall regulation of the system. On the one hand, and without neglecting the interest and insights gained from the cost-benefit analysis, or other approaches of value for money assessment, we will focus our study on the legal, social and political aspects of the regulation of the higher education system and its reform in Portugal. On the other hand, the economic and financial problems have to be taken into account, but in a more inclusive way with regard to the indirect and other socio-economic costs not contemplated in traditional or standard assessments of policies for the tertiary education sector. In the first section of the paper, we will discuss the theoretical and conceptual underpinning of our analysis, focusing on the evolutionary approach, the role of critical institutions, the legal-economic nexus and the problem of order. All these elements are related to the institutional tradition, from Veblen and Commons to Spengler and Samuels. The second section states the problem of regulation in the higher education system and the issue of policy formulation for tackling the problem. The current situation is clearly one of crisis with the expansion of the cohorts of young students coming to an end and the recurrent scandals in private institutions. In the last decade, after a protracted period of extension or expansion of the system, i. e., the continuous growth of students, universities and other institutions are competing harder to gain students and have seen their financial situation at risk. It seems that we are entering a period of radical uncertainty, higher competition and a new configuration that is slowly building up is the growth in intensity, which means upgrading the quality of the higher learning and getting more involvement in vocational training and life-long learning. With this change, and along with other deep ones in the Portuguese society and economy, the current regulation has shown signs of maladjustment. The third section consists of our conclusions on the current issue of regulation and policy challenge. First, we underline the importance of an evolutionary approach to a process of change that is essentially dynamic. A special attention will be given to the issues related to an evolutionary construe of policy analysis and formulation. Second, the integration of law and economics, through the notion of legal economic nexus, allows us to better define the issues of regulation and the concrete problems that the universities are facing. One aspect is the instability of the political measures regarding the public administration and on which the higher education system depends financially, legally and institutionally, to say the least. A corollary is the lack of clear strategy in the policy reforms. Third, our research criticizes several studies, such as the one made by the OECD in late 2006 for the Ministry of Science, Technology and Higher Education, for being too static and neglecting fundamental aspects of regulation such as the logic of actors, groups and organizations who are major players in the system. Finally, simply changing the legal rules will not necessary per se change the behaviors that the authorities want to change. By this, we mean that it is not only remiss of the policy maker to ignore some of the critical issues of regulation, namely the continuous non-respect by academic management and administrative bodies of universities of the legal rules that were once promulgated. Changing the rules does not change the problem, especially without the necessary debates form the different relevant quarters that make up the higher education system. The issues of social interaction remain as intact. Our treatment of the matter will be organized in the following way. In the first section, the theoretical principles are developed in order to be able to study more adequately the higher education transformation with a modest evolutionary theory and a legal and economic nexus of the interactions of the system and the policy challenges. After describing, in the second section, the recent evolution and current working of the higher education in Portugal, we will analyze the legal framework and the current regulatory practices and problems in light of the theoretical framework adopted. We will end with some conclusions on the current problems of regulation and the policy measures that are discusses in recent years.

User-interface technologies for the industrial environment: towards the cyber-factory

In the past few years the so-called gadgets like cellular phones, personal data assistants and digital cameras are more widespread even with less technological aware users. However, for several reasons, the factory-floor itself seems to be hermetic to this changes ... After the fieldbus revolution, the factory-floor has seen an increased use of more and more powerful programmable logic controllers and user interfaces but the way they are used remains almost the same. We believe that new user-computer interaction techniques including multimedia and augmented rcaliry combined with now affordable technologies like wearable computers and wireless networks can change the way the factory personal works together with the roachines and the information system on the factory-floor. This new age is already starting with innovative uses of communication networks on the factory-floor either using "standard" networks or enhancing industrial networks with multimedia and wireless capabilities.
