Practices and trends of telework in the Portuguese industry: the results of surveys in the textile, metal and software sectors

The aim of the TeleRisk Project on labour relations and professional risks within the context of teleworking in Portugal – supported by IDICT – Institute for Development and Inspection of Working Conditions (Ministry of Labour), is to study the practices and forms of teleworking in the manufacturing sectors in Portugal. The project chose also the software industry as a reference sector, even though it does not intend to exclude from the study any other sector of activity or the so-called “hybrid” forms of work. However, the latter must have some of the characteristics of telework. The project thus takes into account the so-called “traditional” sectors of activity, namely textile and machinery and metal engineering (machinery and equipment), not usually associated to this type of work. However, telework could include, in the so-called “traditional” sectors, other variations that are not found in technologically based sectors. One of the evaluation methods for the dynamics associated to telework consisted in carrying out surveys by means of questionnaires, aimed at employers in the sectors analysed. This paper presents some of the results of those surveys. It is important to mention that, being a preliminary analysis, it means that it does not pretend to have exhausted all the issues in the survey, but has meant that it shows the bigger tendencies, in terms of teleworking practices, of the Portuguese industry.

The globalisation in the clothing sector and its implications for work organisation: a view from the Portuguese case

The clothing sector in Portugal is still seen, in many aspects as a traditional sector with some average characteristics, such as: low level of qualifications, less flexible labour legislation and stronger unionisation, very low salaries and low capability of investment in innovation and new technology. Is, nevertheless, a very important sector in terms of labour market, with increased weight in the exporting structure. Globalisation and delocalisation are having a strong impact in the organisation of work and in occupational careers in the sector. With the pressure of global competitiveness in what concerns time and prices, very few companies are able to keep a position in the market without changes in organisation of work and workers. And those that can perform good responses to such challenges are achieving a better economical stability. The companies have found different ways to face this reality according to size, capital and position. We could find two main paths: one where companies outsource a part or the entire production to another territory (for example, several manufacturing tasks), close and/or dismissal the workers. Other path, where companies up skilled their capacities investing, for example, in design, workers training, conception and introduction of new or original products. This paper will present some results from the European project WORKS – Work organisation and restructuring in the knowledge society (6th Framework Programme), focusing the Portuguese case studies in several clothing companies in what concern implications of global context for the companies in general and for the workers in particular, in a comparative analysis with some other European countries.

Futures of automobile industry and challenges on sustainable development and mobility

Portugal had only very few foresight exercises on the automobile sector, and the most recent one was a survey held in a project on work organisation systems in the automobile industry, its recent historical paths and the special strategies of location of companies (the WorTiS project). This involved several teams with different disciplinary backgrounds and from two Portuguese universities. The provisional main results of the first round of a Delphi survey held in Portugal on the automotive sector were already published, but a further analysis was not yet done. This foresight survey was done under the WorTiS project, developed in 2004 by IET – Research Centre on Enterprise and Work Innovation (at FCT-UNL), and financed by the Portuguese Ministry of Science and Technology. Some of this experience on foresight analysis is also been transferred to other projects, namely the WORKS project on work organisation restructuring in the knowledge society that received the support from EC and still is running. The majority of experts considered having an average of less knowledge in almost all the scenario topics presented. This means that information on the automotive industry is not spread enough among academics or experts in related fields (regional scientists, innovation economists, engineers, sociologists). Some have a good knowledge but in very specialised fields. Others have expertise on foresight, or macroeconomics, or management sciences, but feel insecure on issues related with futures of automobile sector. Nevertheless, we considered specially the topics where the experts considered themselves to have some knowledge. There were no “irrelevant” topics considered as such by the expert panel. There are also no topics that are not considered a need for co-operation. The lack of technological infrastructures was not considered as a hindered factor for the accomplishment of any scenario. The experts’ panel considered no other international competence besides US, Japan or Germany in these topics. Special focus will be made in this paper on the topic 2. Public policy and automobile industries, and more specifically on the technological and/or research policies issues, where one can specify the automobile’s role in transport policies with further implications like environment, safety, energy, mobility.

The friction force mouse-pad and the forearm muscles efforts (preliminary results)

The objective of the article is to evaluate the impact of the friction force mouse-pad in the contraction level of the forearm muscles M. extensor carpi ulnaris, M. extensor digitorum and M. extensor carpi radialis longus. A standard protocol of mouse movements was performed involving horizontal, vertical and diagonal mouse displacements drag-and-drop type. The operators were instructed to execute the protocol with their normal working speed. The movements protocol were performed by each subject (n=17) with three selected pairs mouse-pad, classified as low, medium and high friction force pairs. The mean time to execute the protocol with each mouse was ~138s. Mean values of ~13%MVE and ~17%MVE were found in the M. extensor carpi ulnaris and in the M. extensor digitorum respectively when performing the movements’ protocol. A 8.1% increase in %MVE was observed in the M. extensor digitorum and a 9.4% increase in %MVE was observed in the M. extensor carpi ulnaris when the high friction force pair was operated, relatively to the low friction force pair (p<0.05). The main preliminary conclusions of this study is that operating a high friction force mouse-pad may increase the risk to symptoms or disorders in the wrist due to an increase in the forearm muscles contraction levels, particularly during work with drawing application

Epidemiologia e Saúde Públi

RESUMO - Visa-se explicitar a origem, a razão de ser, a natureza e o que se perspectiva da relação entre a Epidemiologia e a Saúde Pública, através de uma leitura histórica. As duas entidades foram-se definindo e fazendo sentido em conjunto, com sucessos e, também, muita polémica, desde há milénios e até meados do século XIX. Nesta época, uma combinação de circunstâncias proporcionou-lhes uma explosão de crescimento e de definição, de par com várias outras áreas disciplinares. Desde o antigo relato bíblico de como boa alimentação explica o bom estado de saúde, até à valorização científica das condicionantes sociais e económicas da saúde por Marmot e Rose, passando por «miasmas» causando doença e pela deslocação do conceito de risco individual de saúde para o de risco populacional — com as implicações inerentes a essa importante inovação —, este percurso permite identificar as fundações de tão notável simbiose, explicar o estado presente, vê-la evoluir e achar nela o significado do património hoje disponível, e o que ele promete. Algumas discrepâncias quanto à designação dos seus métodos, bem como a contínua discussão quanto à sua verdadeira natureza e orientação futura, atestam a juventude da Epidemiologia como disciplina científica. Entretanto, a Saúde Pública esforça-se por manter a sua essência integradora, à medida que outras disciplinas contribuem mais para que concretize os seus objectivos; é desafiada pela exposição das populações, em larga escala, a factores de doença, por vezes de intensidade mínima, e pelo surgimento de novas doenças ou a ampliação do volume de outras na população, muitas vezes não respeitando fronteiras. A história dessa simbiose mostra bem que conhecer o modo como uma doença se origina permite controlá-la na população, ou mesmo evitá-la, e que é grande o número de problemas que, em sinergia, as duas disciplinas podem clarificar e resolver. Assim, a Epidemiologia oferece à Saúde Pública explicações (olhos, inteligência e linguagem) para os problemas de saúde das populações — o que permite à segunda saber sobre o quê agir —, cenários de possível evolução dos problemas — o que permite aos decisores optarem em função de diferentes pressupostos, sobre como agir — e capacidade de juízo sobre os resultados das acções empreendidas, em simultâneo com a elevação do nível de consciência, de compreensão e de intervenção quanto ao que se está a passar, tanto pelos profissionais, como pela população — transferência do conhecimento. Facilmente se antecipa que a relação entre as duas disciplinas irá evoluir para maior complexidade e, também, solicitação e exigência da Saúde Pública sobre a Epidemiologia, que terá que corresponder em utilidade. E esta, continuando a subespecializar-se e a sofisticar-se tanto nos métodos, como nos enfoques sobre categorias específicas de factores, precisará de progredir muito na gestão da sua consistência enquanto corpo de conhecimento integrado e com peculiaridades metodológicas, à semelhança da Saúde Pública.O modo como evoluirá a relação entre ambas depende ainda da evolução dos próprios problemas, conceitos, teorias e soluções relacionados com a saúde das populações, e ainda do desenvolvimento das demais disciplinas chamadas à integração por ambas, para enfrentarem esses desafios. Nomeadamente, a Epidemiologia terá que gerir com perícia dificuldades já identificadas, como: incorporar métodos qualitativos de investigação na sua fortíssima tradição e cultura quantitativa; operacionalizar satisfatoriamente o conceito de «risco atribuível na população», ao serviço da definição de prioridades de acção dirigida às necessidades de saúde; aperfeiçoar modelos de interpretação causal que respeitem a multicausalidade; aproveitar as técnicas estatísticas de análise multivariada, sem se perder na abstracção dos seus modelos; desenvolver a investigação nas dimensões positivas de saúde, além da doença, para contribuir melhor para a realização da Saúde Pública, sua principal cliente e fornecedora de oportunidades.--------------------------ABSTRACT - The aim of the author is to explicit the origin, the rationale, the nature and the prospects of the relationship between Epidemiology and Public health, through an historic approach. The two entities have been defining and making sense together, by achieving successes, but also with much controversy, since millennia ago, until mid XIX century. A combination of circumstances provided them the opportunity for an explosion of growth and definition, then, alongside several other disciplines. From the ancient biblical report on how good food explains good health, up to the scientific appreciation of both social and economical constraints to health by Marmot and Rose, passing through «miasma» causing disease and through displacing from individual health risk to population risk — with the inherent implications of that important innovation —, this route allows the identification of the foundations of such remarkable symbiosis, the explanation of current status, to see its evolution and find in it the meaning of today’s heritage and what it promises. Some discrepancies on the name of its methods, as well as the continuing discussion about its true nature and future orientation, attest Epidemiology’s youth as a scientific discipline. Meanwhile, Public Health strives to keep its integrating essence, while other disciplines increasingly contribute so that it achieves its objectives; it is challenged by large scale population exposure to disease factors, sometimes with a minimum intensity, and by new diseases emerging in the population or by old ones getting amplified, often not respecting regions boundaries. The history of such a symbiosis shows that knowing the way a disease is generated allows to control it in the population, or even to avoid it, and that the number of problems that the two disciplines are able to clarify and solve together in synergy is considerable. Therefore, Epidemiology offers Public Health explanations (eyes, intelligence and language) for populations’s health problems — allowing that the latter knows on what to act —, scenarios on how problems may tend to evolve — allowing decision-makers to make their choices as a function of different assumptions, on how to act — and judgement capabilities on the results of already undertaken actions, accompanied by the raising of conscience level, understanding and intervention of what is going on by both professionals and the population – knowledge transfer. It is easy to anticipate that the relationship between both disciplines will develop towards increasing complexity and demand from Public Health to Epidemiology, and that this one will have to correspond in usefulness. And the latter, while continuing its subspecialisation and sophistication either in its methods, or in its approaches to specific factor categories, will need to progress in managing its consistency as an integrated body of knowledge having methodological peculiarities, similarly to Public Health. Further, the way the relationship between both will evolve depends on the evolution of the problems themselves, of the concepts, theories and solutions related to the health of populations, and on the development of remaining disciplines called to integration by both, in other to face those problems. Namely, Epidemiology will have to manage with expertise some already known difficulties, as: the inclusion of qualitative research methods in its very strong quantitative tradition and culture; to grant satisfactory operation to the «population attributable risk» concept, in support to the definition of action priorities envisaging health needs; to improve causal interpretation models that comply with multicausality; to take advantage of multivariate statistical techniques, without get
