Digital storytelling: an integrated approach to language for the 21st century student

Societal changes have, throughout history, pushed the long-established boundaries of education across all grade levels. Technology and media merge with education in a continuous complex social process with human consequences and effects. We, teachers, can aspire to understand and interpret this volatile context that is being redesigned at the same time society itself is being reshaped as a result of the technological evolution. The language- learning classroom is not impenetrable to these transformations. Rather, it can perhaps be seen as a playground where teachers and students gather to combine the past and the present in an integrated approach. We draw on the results from a previous study and argue that Digital Storytelling as a Process is capable of aggregating and fostering positive student development in general, as well as enhancing interpersonal relationships and self-knowledge while improving digital literacy. Additionally, we establish a link between the four basic language-learning skills and the Digital Storytelling process and demonstrate how these converge into what can be labeled as an integrated language learning approach.

An Evaluation of clinical, serologic, anatomopathologic and immunohistochemical findings for fifteen patients with mucosal leishmaniasis before and after treatment

Treatment of mucosal leishmaniasis (ML) can be controlled by clinical examination and by serologic titers by the indirect immunofluorescence serologic reaction (IISR). We studied the correlation between the presence of antigen in tissue determined by immunohistochemistry, the IISR titers and the anatomopathologic findings in fifteen patients with ML before and after healing of the lesions as determined by otorhinolaryngologic evaluation, and evaluated these parameters to determine which of them could be useful during follow-up. Tissue antigens became negative in four patients (group A) after treatment, with a statistically significant reduction or negativity of IISR titers (p<0.05). This did not occur in patients in whom the antigen persisted after treatment (group B), suggesting that serologic follow-up should be performed together with the search for tissue antigen, a combination which, to our knowledge, has not been used in previous studies. The negativity of tissue antigens and the behavior of IIRS titers in group A patients probably indicate a lower possibility of recurrence. Upon anatomopathologic examination the inflammatory process was found to persist after treatment even in group A, suggesting that the permanence of inflammatory activity even in clinically healed lesions is possibly correlated with the presence of the antigen or of some unknown factor.

Projecto e concepção de um dispositivo experimental para medição e caracterização dos esforços aplicados no finca-pés de um caiaque de pista: Investigação, desenho e desenvolvimento

Após o enquadramento da canoagem, como modalidade Olímpica, verificou-se um aumento significativo de estudos e pesquisas acerca da biomecânica da modalidade, o que contribuiu para uma diminuição dos tempos na competição. Contudo poucos foram os que se focaram nas forças desenvolvidas e aplicadas ao caiaque através do finca-pés, criado assim oportunidade de desenvolvimento de dispositivos para a medição das mesmas. Assim, o objectivo primordial é desenvolver um sistema experimental capaz de quantificar as forças geradas em cada um dos lados do finca-pés (esquerdo e direito). Este, deverá não só ser passível de se utilizar em caiaque ergómetro como também num caiaque de pista, permitido avaliar as forças aplicadas durante o ciclo de pagaiada, tanto em compressão como em tracção. A sua concepção baseou-se num modelo de finca-pés já existente, tornando-o compatível com os caiaques de competição mais comercializados, e permitindo que no futuro se possa utilizar na água, bastando para isso apenas possuir um caiaque e embarcar o sistema de medição. Este sistema experimental foi testado em caiaque ergómetro por 7 (sete) sujeitos com níveis distintos: seis homens (um atleta olímpico medalhado e cinco de nível nacional) e uma mulher (de nível de selecção Portuguesa) que, entre outros, realizaram um plano definido por 60s a uma frequência de 75 pagaiadas por minuto, seguido de uma intensa mudança de ritmo e força (Sprint). Após análise dos dados obtidos em cada um dos diferentes sujeitos, conseguimos identificar algumas das suas características, tais como: esforço assimétrico dos membros inferiores; utilização de forma heterogénea da fita do finca-pés; diferença de forças máximas aplicadas entre atletas (Ex.: para um atleta olímpico as forças medidas (Min; Max): Pé Esquerdo (- 444; 1087) N e Pé Direito (- 476; 1068) N); etc. Os resultados não só são bastante promissores como também são motivantes e congruentes com estudos anteriores, nomeadamente Begon et al. 2008 e Sturm 2010 e 2012. Finalmente, consegue-se afirmar, com segurança, que foram alcançados os objectivos propostos com a concepção deste dispositivo de medição de forças. Este permite caracterizar os esforços desenvolvidos no finca-pés por cada membro inferior, com ou sem a fita de suporte, possibilitando aos treinadores e atletas uma visão, para muitos desconhecida, das forças transmitidas e das suas assimetrias. No final, este conhecimento permitirá aos atletas melhorar o seu desempenho desportivo bem como facilitar a gestão desportiva, com base nos principais princípios mecânicos inerentes ao movimento dos atletas desde desporto Olímpico.

Expatriates’ influence on knowledge sharing: an empirical study with International portuguese companies

Despite the abundant literature in knowledge management, few empirical studies have explored knowledge management in connection with international assignees. This phenomenon has a special relevance in the Portuguese context, since (a) there are no empirical studies concerning this issue that involves international Portuguese companies; (b) the national business reality is incipient as far as internationalisation is concerned, and; (c) the organisational and national culture presents characteristics that are distinctive from the most highly studied contexts (e.g., Asia, USA, Scandinavian countries, Spain, France, The Netherlands, Germany, England and Russia). We examine the role of expatriates in transfer and knowledge sharing within the Portuguese companies with operations abroad. We focus specifically on expatriates’ role on knowledge sharing connected to international Portuguese companies and our findings take into account organizational representatives’ and expatriates’ perspectives. Using a comparative case study approach, we examine how three main dimensions influence the role of expatriates in knowledge sharing among headquarters and their subsidiaries (types of international assignment, reasons for using expatriation and international assignment characteristics). Data were collected using semi‐structured interviews to 30 Portuguese repatriates and 14 organizational representatives from seven Portuguese companies. The findings suggest that the reasons that lead Portuguese companies to expatriating employees are connected to: (1) business expansion needs; (2) control of international operations and; (3) transfer and knowledge sharing. Our study also shows that Portuguese companies use international assignments in order to positively respond to the increasingly decaying domestic market in the economic areas in which they operate. Evidence also reveals that expatriation is seen as a strategy to fulfill main organizational objectives through their expatriates (e.g., business internationalization, improvement of the coordination and control level of the units/subsidiaries abroad, replication of aspects of the home base, development and incorporation of new organizational techniques and processes). We also conclude that Portuguese companies have developed an International Human Resources Management strategy, based on an ethnocentric approach, typically associated with companies in early stages of internationalization, i.e., the authority and decision making are centered in the home base. Expatriates have a central role in transmitting culture and technical knowledge from company’s headquarters to the company’s branches. Based on the findings, the article will discuss in detail the main theoretical and managerial implications. Suggestions for further research will also be presented.

Human capital in the knowledge-based society: comparative analysis: Romania-Portugal

The current economic crisis has rushed even more the economists’ concerns to identify new directions for the sustainable development of the society. In this context, the human capital is crystallised as the key variable of the creative economy and of the knowledge-based society. As such, we have directed the research underlying this paper to identifying the most eloquent indicators of human capital to meet the demands of the knowledge-based society and sustainable development as well as towards achieving a comprehensive analysis of the human capital in the EU countries, respectively of a comparative analysis: Romania - Portugal. To carry out this paper, the methodology used is based on the interdisciplinary triangulation involving approaches from the perspective of human resource management, economy and economic statistics. The research techniques used consist of the content analysis and investigation of secondary data of international organisations accredited in the field of this research, such as: the United Nation Development Programme - Human Development Reports, World Bank - World Development Reports, International Labour Organisation, Eurostat, European Commission’s Eurobarometer surveys and reports on human capital. The research results emphasise both similarities and differences between the two countries under the comparative analysis and the main directions in which one has to invest for the development of human capital.

Knowledge Society and Geography: A Theoretical Approach

The transition process between information and knowledge is faster and so the inputs that influence social and political practises. The dissemination of information is now determinant in terms of territorial competitiveness and both public and private sector take large benefits when the data-information- knowledge value chain repeats itself trough space and time. Mankind depends nowadays on the creation and diffusion of good and reliable information. Speed is also important and the greater the speed, the faster the opportunities for global markets. Information must be an input for knowledge and obviously for decision. So, the power of information is unquestionable. This paper focuses on concepts like information, knowledge and other, more geographical and tries to explain how territories change from real to virtual. Knowledge society appears on an evolutional context in which information dissemination is wider and technological potential overwrites traditional notions of Geography. To understand the mutations over the territories, the causes and the consequences emerges the Geography of the Knowledge Society, a new discipline inside Geography with a special concern about modern society and socio-economical developing models.

Are societal changes new? Questions or trends and future perceptions on knowledge-based economy

With the emergence of a global division of labour, the internationalisation of markets and cultures, the growing power of supranational organisations and the spread of new information technologies to every field of life, it starts to appear a different kind of society, different from the industrial society, and called by many as ‘the knowledge-based economy’, emphasizing the importance of information and knowledge in many areas of work and organisation of societies. Despite the common trends of evolution, these transformations do not necessarily produce a convergence of national and regional social and economic structures, but a diversity of realities emerging from the relations between economic and political context on one hand and the companies and their strategies on the other. In this sense, which future can we expect to the knowledge economy? How can we measure it and why is it important? This paper will present some results from the European project WORKS – Work organisation and restructuring in the knowledge society (6th Framework Programme), focusing the future visions and possible future trends in different countries, sectors and industries, given empirical evidences of the case studies applied in several European countries, underling the importance of foresight exercises to design policies, prevent uncontrolled risks and anticipate alternatives, leading to different ‘knowledge economies’ and not to the ‘knowled
