ePortfolios in translators’ training and assessment

Translator’s training and assessment has used more and more tools and innovative strategies over the years. The goals and results to achieve haven’t changed much, however: translation quality. In order to accomplish it, the translator and all the tasks and processes he develops appear as crucial, being pre-translation and post-translation processes equally important as the translation itself, namely as far as autonomy, reflexive and critical skills are concerned. Finally, the need and relevance of 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. In this paper we describe a case-study of a pilot experiment on the using of e-portfolios as a translation training tool and discuss their role in the definition of a clear set of objectives and 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 of eportfolios.

Moodle and multiple-choice tests

Multiple-Choice items are used in many different kinds of tests in several areas of knowledge. They can be considered an interesting tool to the self-assessing or as an alternative or complementary instrument to the traditional methods for assessing knowledge. The objectivity and accuracy of the multiple-choice tests is an important reason to think about. They are especially useful when the number of students to evaluate is too large. Moodle (Modular Object-Oriented Dynamic Learning Environment) is an Open Source course management system centered around learners' needs and designed to support collaborative approaches to teaching and learning. Moodle offers to the users a rich interface, context-specific help buttons, and a wide variety of tools such as discussion forums, wikis, chat, surveys, quizzes, glossaries, journals, grade books and more, that allow them to learn and collaborate in a truly interactive space. Come together the interactivity of the Moodle platform and the objectivity of this kind of tests one can easily build manifold random tests. The proposal of this paper is to relate our journey in the construction of these tests and share our experience in the use of the Moodle platform to create, take advantage and improve the multiple-choices tests in the Mathematic area.

The Role of lifelong learning in creation of a european knowledge-based society

The dominant discourse in education and training policies, at the turn of the millennium, was on lifelong learning (LLL) in the context of a knowledge-based society. As Green points (2002, pp. 611-612) several factors contribute to this global trend: The demographic change: In most advanced countries, the average age of the population is increasing, as people live longer; The effects of globalisation: Including both economic restructuring and cultural change which have impacts on the world of education; Global economic restructuring: Which causes, for example, a more intense demand for a higher order of skills; the intensified economic competition, forcing a wave of restructuring and creating enormous pressure to train and retrain the workforce In parallel, the “significance of the international division of labour cannot be underestimated for higher education”, as pointed out by Jarvis (1999, p. 250). This author goes on to argue that globalisation has exacerbated differentiation in the labour market, with the First World converting faster to a knowledge economy and a service society, while a great deal of the actual manufacturing is done elsewhere.

Organization knowledge management change from a complex adaptive systems perpective with ability for ambidexeterity

We are working on the confluence of knowledge management, organizational memory and emergent knowledge with the lens of complex adaptive systems. In order to be fundamentally sustainable organizations search for an adaptive need for managing ambidexterity of day-to-day work and innovation. An organization is an entity of a systemic nature, composed of groups of people who interact to achieve common objectives, making it necessary to capture, store and share interactions knowledge with the organization, this knowledge can be generated in intra-organizational or inter-organizational level. The organizations have organizational memory of knowledge of supported on the Information technology and systems. Each organization, especially in times of uncertainty and radical changes, to meet the demands of the environment, needs timely and sized knowledge on the basis of tacit and explicit. This sizing is a learning process resulting from the interaction that emerges from the relationship between the tacit and explicit knowledge and which we are framing within an approach of Complex Adaptive Systems. The use of complex adaptive systems for building the emerging interdependent relationship, will produce emergent knowledge that will improve the organization unique developing.

Knowledge extraction from medium voltage load diagrams to support the definition of electrical tariffs

With the electricity market liberalization, distribution and retail companies are looking for better market strategies based on adequate information upon the consumption patterns of its electricity customers. In this environment all consumers are free to choose their electricity supplier. A fair insight on the customer´s behaviour will permit the definition of specific contract aspects based on the different consumption patterns. In this paper Data Mining (DM) techniques are applied to electricity consumption data from a utility client’s database. To form the different customer´s classes, and find a set of representative consumption patterns, we have used the Two-Step algorithm which is a hierarchical clustering algorithm. Each consumer class will be represented by its load profile resulting from the clustering operation. Next, to characterize each consumer class a classification model will be constructed with the C5.0 classification algorithm.

Symbolic Knowledge Extraction from Trained Neural Networks Governed by Lukasiewicz Logics

This work describes a methodology to extract symbolic rules from trained neural networks. In our approach, patterns on the network are codified using formulas on a Lukasiewicz logic. For this we take advantage of the fact that every connective in this multi-valued logic can be evaluated by a neuron in an artificial network having, by activation function the identity truncated to zero and one. This fact simplifies symbolic rule extraction and allows the easy injection of formulas into a network architecture. We trained this type of neural network using a back-propagation algorithm based on Levenderg-Marquardt algorithm, where in each learning iteration, we restricted the knowledge dissemination in the network structure. This makes the descriptive power of produced neural networks similar to the descriptive power of Lukasiewicz logic language, minimizing the information loss on the translation between connectionist and symbolic structures. To avoid redundance on the generated network, the method simplifies them in a pruning phase, using the "Optimal Brain Surgeon" algorithm. We tested this method on the task of finding the formula used on the generation of a given truth table. For real data tests, we selected the Mushrooms data set, available on the UCI Machine Learning Repository.

The influence of curing conditions on the mechanical performance of concrete made with recycled concrete waste

Research on the use of Construction and Demolition Waste (CDW) as recycled aggregate (in particular crushed concrete) for the production of new concrete has by now established the feasibility of this environmentally-friendly use of otherwise harmful waste. However, contrary to conventional concrete (CC), no large applications of concrete made with recycled concrete have been made and there is still a lack of knowledge in some areas of production and performance of recycled aggregate concrete (RAC). One issue concerns curing conditions: these greatly affect the performance of concrete made on site and some potential users of RAC wonder how RAC is affected by far-from-ideal curing conditions. This paper shows the main results of experiments to determine the influence of different curing conditions on the mechanical performance of concrete made with coarse recycled aggregate from crushed concrete. The properties analyzed include compressive strength, splitting tensile strength, modulus of elasticity, and abrasion resistance. The general conclusion in terms of mechanical performance is that RAC is affected by curing conditions roughly in the same way as CC. (C) 2011 Elsevier Ltd. All rights reserved.

Formação contínua e supervisão pedagógica: o impacto do Programa Nacional do Ensino do Português no desenvolvimento profissional de professores do 1º Ciclo do Ensino Básico

Este estudo pretende descrever e compreender o processo formativo dos professores do 1º ciclo do Ensino Básico, no contexto do Programa Nacional de Ensino do Português (PNEP), as suas dimensões mais relevantes e como é percecionada a supervisão nesse processo de formação contínua. A metodologia adotada nesta investigação foi de natureza qualitativa e baseou-se num conjunto de entrevistas semi-diretivas realizadas a formandos que frequentaram o PNEP entre 2008/2010. Dos resultados obtidos foi possível verificar o impacto positivo que esta modalidade de formação contínua teve no desenvolvimento profissional dos professores preparando-os para a implementação do novo programa de português e permitindo-lhes desmistificar o papel do supervisor através da participação numa experiência de supervisão. O trabalho colaborativo entre professores emergiu durante este processo formativo fomentando a construção de saber em colaboração. A prática pedagógica dos professores apresentou mudanças que pretenderam repercutir-se no aproveitamento dos alunos na área da língua portuguesa. - Abstract This study aims to comprehend and describe the formative process and practice of teachers in Basic education (1st Cycle), in the context of the National Programme for the Teaching of Portuguese Language (PNEP), its most relevant dimensions, the factors which affected it and how supervision was perceived by the teachers involved. A qualitative approach was used, based on semi-directed interviews done to teachers that attended the PNEP, from 2008 to 2010. The impact of this type of continuing training on teachers‟ professional development was positive. They felt prepared for the implementation of the new Portuguese Language Programme. They also demystified the role of the supervisor through the participation in an experience of supervision. The teachers‟ collaborative work emerged during this formative process, promoting the construction of knowledge among teachers. Added to this, teachers‟ pedagogical practice also improved reflected on the students‟ proficiency in the Portuguese language.

Os seguros na gestão de uma obra

Neste trabalho pretende-se evidenciar algumas práticas que podem e devem ser adotadas na direção de empreitadas, de modo a reduzir os riscos de uma obra através de uma gestão apropriada de seguros, acautelando, contudo, o equilíbrio entre o custo e respetivas coberturas. Os seguros de Construção, internacionalmente designados por “All risks” (todos os riscos de construção), são uma questão pouco explorada apesar da sua elevada importância para a atividade, pois os custos que possam decorrer de um sinistro poderão ter um impacto muito significativo para as empresas. Por vezes, estes seguros são encarados como mais um encargo e não como um mecanismo de gestão de Risco. Do conhecimento profundo que a empresa construtora detém sobre a particularidade da sua obra, esta procura todos os tipos de seguro que melhor se enquadram nas suas necessidades, que aliadas a pessoas especializadas na matéria, aconselham e gerem os seguros de obra, de maneira a que, em caso de ocorrência de um sinistro, não existam surpresas para o segurado. Por fim, é importante associar e entender a importância da relação que existe entre risco, interesse e seguro na gestão de uma obra.
