Adaptação ocupacional de indivíduos obesos a partir dos conceitos de identidade e competência ocupacional: associação com os níveis de atividade física e os valores máximos de pressão plantar

A Obesidade é considerada um grave problema de saúde pública, com consequências negativas para os indivíduos obesos, nomeadamente dificuldades no desempenho de atividades de vida diária, na locomoção e na prática de exercício físico, o que pode restringir a participação em atividades sociais e de lazer. Esta investigação consiste num estudo quantitativo descritivo e tem como objetivo principal descrever de que forma os indivíduos adultos obesos classificam a sua adaptação ocupacional, a partir dos conceitos de identidade e competência ocupacional. Com este estudo, pretende-se ainda verificar se os indivíduos obesos apresentam níveis de atividade física mais baixos e valores mais elevados de pressão plantar, em relação a indivíduos com peso normal. A amostra é constituída por dez indivíduos adultos, de ambos os sexos, com índice de massa corporal igual (IMC) ou superior a 30 Kg/m2, e os instrumentos de avaliação utilizados são o Questionário Ocupacional (adaptado por N. Riopel com assistência de G. Kielhofner e J. Hawkins Watts – 1986), o IPAQ – Versão Curta e o Sistema de Palmilhas Pedar. A partir dos resultados, pode-se verificar que os indivíduos obesos apresentam uma rotina diária em que a maioria das atividades realizadas está relacionada com a casa, o trabalho e o descanso e que a percentagem de atividades de lazer em que participam é reduzida. No entanto, parecem satisfeitos com o seu desempenho na maior parte das atividades, consideram que muitas delas são importantes para si e estão motivados para as realizar. Dos resultados obtidos, podemos sugerir que os indivíduos obesos apresentam boa adaptação ocupacional. Pode-se ainda dizer que os indivíduos obesos apresentam um baixo nível de intensidade de atividade física, não se observando diferenças significativas relativamente aos indivíduos com peso normativo e que os seus valores máximos de pressão plantar normalizados são inferiores quando comparados com a população de peso normal.

Transtextualidade na tradução de "Der mann im fahrstuhl / The mann in the elevator"

In an age where Babel has turned into transcultural communication, an interlingual approach – i.e. in English and in French – to the translating process from German to Portuguese appeared pertinent. Aiming at a refinement of the translating competence, this process consists in contrasting different linguistic and literary strategies through an intercultural and multi-etymological perspective. Thus, we settled upon Heiner Müller‘s play Der Auftrag. Erinnerung an eine Revolution (1980), on which the composer Heiner Goebbels has based himself to textually and musically dramatize an excerpt, Der Mann im Farhstuhl / The Man in the Elevator. A transcription of such excerpt in its source language, German, as well as its translation into English (Carl Weber, 1984, Performing Arts Publications, New York) and French (Jean Jourdheuil, Heinz Schwarzinger, Editions Minuit, Paris) can be found in the booklet that accompanies the CD – edited in 1988 by ECD (München: Records GmbH). It should be emphasized that such a creation allows a framing of Müller‘s text into a musical scenography and, therefore, encourages an intersemiotic contrast. This experience enabled us to come up with a unique imagery of Müller‘s piece of writing, by means of its dramatic and musical conversion and, simultaneously, lead us to stretch our textual consciousness to a multitude of intra-, extra- and interlinguistic elements.

Knowledge management in multinational companies: the repatriates’ role in the competitive advantage in subsidiaries

This paper addresses the topic of knowledge management in multinational companies (MNCs). Its purpose is to examine the role of expatriates in knowledge acquisition and transfer within MNCs. Specifically it focuses on knowledge acquisition and transfer from one MNC head office located in Germany to two Portuguese subsidiaries as a basis for competitive advantage in their Portuguese subsidiaries. A qualitative research methodology is used, specifically through an exploratory case study approach, which examines how international assignments are important for the role of expatriates In knowledge acquisition and transfer between foreign head offices and their Portuguese subsidiaries. The data were collected through semi structured interviews to 10 Portuguese repatriates from two Portuguese subsidiaries of one foreign MNC. The findings suggest that the reasons that lead to expatriating employees from Portuguese subsidiaries to foreign head offices are connected to (1) knowledge management strategies to development the subsidiary’s performance; (2) new skills and knowledge acquisition by future team leaders and business/product managers in Portuguese subsidiaries; (3) procuring knowledge, from agents in head office, to be disseminated amongst co-workers in Portuguese subsidiaries; (4) acquiring global management skills, impossible to acquire locally and; (5) developing global projects within MNC. Also our results show that knowledge acquisition and transfer from foreign head office, through subsidiaries’ expatriates, contributes directly to the Portuguese subsidiaries’ innovation, improved performance, competitive advantage and growth in the economic sectors in which they operate. Moreover, evidence reveals that expatriation is seen as a strategy to fulfil some of the main organisational objectives through their expatriates (e.g., create new products and business markets, develop and incorporate new organisational techniques and processes, integrate global teams within multinational corporation with a responsibility on the definition of global objectives). The results obtained suggest that expatriates have a central role in acquiring and transferring strategic knowledge from MNC head office to their subsidiaries located in Portugal. Based on the findings, the paper discusses in detail the main theoretical and managerial implications. Suggestions for further research are also presented. The study’s main limitation is the small size of the sample, but its findings and methodology are quite original and significant.

Environmental Decision Support: a Distributed Artificial Intelligence Approach

Decision making in any environmental domain is a complex and demanding activity, justifying the development of dedicated decision support systems. Every decision is confronted with a large variety and amount of constraints to satisfy as well as contradictory interests that must be sensibly accommodated. The first stage of a project evaluation is its submission to the relevant group of public (and private) agencies. The individual role of each agency is to verify, within its domain of competence, the fulfilment of the set of applicable regulations. The scope of the involved agencies is wide and ranges from evaluation abilities on the technical or economical domains to evaluation competences on the environmental or social areas. The second project evaluation stage involves the gathering of the recommendations of the individual agencies and their justified merge to produce the final conclusion. The incorporation and accommodation of the consulted agencies opinions is of extreme importance: opinions may not only differ, but can be interdependent, complementary, irreconcilable or, simply, independent. The definition of adequate methodologies to sensibly merge, whenever possible, the existing perspectives while preserving the overall legality of the system, will lead to the making of sound justified decisions. The proposed Environmental Decision Support System models the project evaluation activity and aims to assist developers in the selection of adequate locations for their projects, guaranteeing their compliance with the applicable regulations.

Mitochondria are the main source and one of the targets of Pb (lead)-induced oxidative stress in the yeast Saccharomyces cerevisiae

The yeast Saccharomyces cerevisiae is a useful model organism for studying lead (Pb) toxicity. Yeast cells of a laboratory S. cerevisiae strain (WT strain) were incubated with Pb concentrations up to 1,000 μmol/l for 3 h. Cells exposed to Pb lost proliferation capacity without damage to the cell membrane, and they accumulated intracellular superoxide anion (O2 .−) and hydrogen peroxide (H2O2). The involvement of the mitochondrial electron transport chain (ETC) in the generation of reactive oxygen species (ROS) induced by Pb was evaluated. For this purpose, an isogenic derivative ρ0 strain, lacking mitochondrial DNA, was used. The ρ0 strain, without respiratory competence, displayed a lower intracellular ROS accumulation and a higher resistance to Pb compared to the WT strain. The kinetic study of ROS generation in yeast cells exposed to Pb showed that the production of O2 .− precedes the accumulation of H2O2, which is compatible with the leakage of electrons from the mitochondrial ETC. Yeast cells exposed to Pb displayed mutations at the mitochondrial DNA level. This is most likely a consequence of oxidative stress. In conclusion, mitochondria are an important source of Pb-induced ROS and, simultaneously, one of the targets of its toxicity.

El cambio del perfil del profesional de recursos humanos en Portugal

El presente estudio pretende caracterizar el perfil de los profesionales responsables por la gestión de recursos humanos, en concreto su perfil académico, las funciones que ocupan y los requisitos demandados por las empresas portuguesas que pretenden admitir a nuevos profesionales para asumir funciones en el ámbito de la gestión de personas. Este estudio está basado en una encuesta por cuestionario realizado a una muestra de 261 responsables de recursos humanos de empresas ubicadas en Portugal (133 fueron encuestados en 2004, 128 fueron encuestados en 2013). En paralelo, fueron analizados 78 anuncios publicados en 2014 para identificar el perfil requerido en la actualidad. Los resultados muestran que, durante los últimos 10 años, la gran parte de los profesionales responsables por la gestión de recursos humanos asumen papeles específicos relacionados con los recursos humanos (RH). La calificación superior en RH empieza logrando más importancia en 2013, cuando se compara con otras áreas de calificación superior (ej. Gestión, Derecho e Ingeniería) prevalecientes en 2004. Las vacantes disponibles en anuncios relacionados con la función de RH buscan, sobretodo, candidatos (1) para asumir el cargo de técnico de RH, (2) que posean calificación superior en las áreas de RH o Ciencias Sociales y (3) que detengan competencias personales e interpersonales, así como competencias lingüísticas e informáticas. Basado en estos resultados, el artículo discute en detalle las principales implicaciones teóricas y prácticas. Sugestiones de investigación futura son, de igual modo, presentadas.

Assessing Reading Abilities of Mechanical Engineering College Students: A Prospecting Study*

Reading is a basic competence that students have to master to be successful. Despite this fact, recent studies show that there may be a significant decline in the reading abilities of college students, one of the most educated segments of any population. This work is a prospecting study regarding the assessment of reading abilities of college students, namely in the context of Engineering education. Based on an existing screening test for assessing reading difficulties of children and teenagers, this work presents the results obtained by administrating that test to students at a top engineering institution in Portugal. An outcome of this study is the determination of a time range suitable for a massive, time limited, use of the previously mentioned test to assess college students, thus enabling a basic tool that will permit, in future works, to screen reading abilities in wider college populations. This work also shows evidence that ca. 20% of college students present a poor reading performance, revealing a strong need for monitoring college students’ reading abilities along different generations.

Expatriates recruitment and selection for long-term international assignments in portuguese companies

Long-term international assignments’ increase requires more attention being paid for the preparation of these foreign assignments, especially on the recruitment and selection process of expatriates. This article explores how the recruitment and selection process of expatriates is developed in Portuguese companies, examining the main criteria on recruitment and selection of expatriates’ decision to send international assignments. The paper is based on qualitative case studies of companies located in Portugal. The data were collected through semi-structured interviews of 42 expatriates and 18 organisational representatives as well from nine Portuguese companies. The findings show that the most important criteria are: (1) trust from managers, (2) years in service, (3) previous technical and language competences, (4) organisational knowledge and, (5) availability. Based on the findings, the article discusses in detail the main theoretical and managerial implications. Suggestions for further research are also presented.

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.
