Main features of the labour policy in Portugal

In this working paper is presented information on the Portuguese labour market developed with the support of the European project WORKS-“Work organisation and restructuring in the knowledge society”. Is still a on the process article and thus commentaries are welcome. The structure is based on the following topics: a) The employment policy (Time regimes - time use, flexibility, part-time work, work-life balance -, and the work contracts regimes – wages, contract types, diversity); b) Education and training (skilling outcomes, rules on retraining and further training, employability schemes, transferability of skills); c) Equal opportunities (relevance of equal opportunity regulation for restructuring outcomes, the role of gender and age regulation); d) Restructuring effects (policy on transfer of personnel, policy on redundancies, and participation or voice in restructuring).

Tendências futuras de evolução das qualificações na Europa

The aim of this report is to highlight the importance of foresight exercises as a necessary tool to help the decision makers, allowing through projections and identification of the main trends, the identification of the key variables of the process and which ones may have more influence in the process of evolution of societies. It will be presented some examples of prospective methods and also scenarios construction. One example is the European project WORKS (Work organization restructuring in the knowledge society) that pretend to built a set of scenarios about the possible evolution of work in Europe in a short, medium and long term, stressing the key variables that may have an important role in the process and their interconnections. Another exemple is the report ‘Future skill needs in Europe’ prepared in 2008 by Cedefop, that presents data about the future development of employment by industry, occupation and qualification by 2015.

Change Processes and Future Perspectives in the Knowledge Society. The Example of Clothing and Textile Industry

The paper examines change processes und future perspectives in the knowledge society. It presents the clothing and textile industry as an example for a transforming industry in a global economy. The paper reviews existing future studies, which have surveyed change processes and future developments in the clothing and textile industry. Main goals of the review are the identification of changes in work and the description of the restructuring of global value chains within the clothing and textile sector. The paper also highlights major current trends, drivers of change and future prospects in this sector.

The First WORKS Conference on Transformation of Work in a Global Knowledge Economy

The relationship between the changes of the global economy and individual working conditions formed the background of the first WORKS conference “The transformation of work in a global knowledge economy: towards a conceptual framework”, held in Chania, Greece from 21st – 22nd September, 2006 and attended by around 50 European researchers. Experts from academia and trade unions from all over the world were invited to give insights into their field of research, contributing to one of the main topics of the conference: (i) globalisation and organisational restructuring, (ii) workers’ organisation, the quality of working life and the gender dimension and (iii) global experiences and recommendations.

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.

Application of FTA and the perceived impact on employment policies: the case of nanotechnology in the Netherlands, Germany and Portugal

In this paper we will analyse the usage of FTA to support decision-making in employment policy relate to specific occupational groups. The examples can be better understood if one focus on the nanotechnology and its implications on some sectors (clothing, bio-medical engineering, micro-electronics). When this is done will be clear which occupations will engage a restructuring process (engineers, specialised technicians, qualified machine operators, quality controllers) and what policies are being designed to cope with it. This means toward which extend social partners have driven specific policies on these issues (focused in their sectors).

International Conference on “Foresight Studies on Work in the Knowledge Society“ in Monte de Caparica (FCT-UNL) on 19-20 October 2006

On 19 and 20 October 2006, the Research Centre on Enterprise and Work Organisation (IET) organised the first international conference on “Foresight Studies on Work in the Knowledge Society”. It took place at the auditorium of the new Library of FCT-UNL and had the support of the research project “CodeWork@VO” (financed by FCT-MCTES and co-ordinated by INESC, Porto). The conference related to the European research project “Work Organisation and Restructuring in the Knowledge Society” (WORKS), which is financed by the European Commission. The main objective of the conference was to analyse and discuss research findings on the trends of work structures in the knowledge society, and to debate on new work organisation models and new forms of work supported by ICT.

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.

Caracterização da função do monóxido de azoto e glutationo hepáticos na sensabilidade periférica à insulina

xi RESUMO A acção da insulina no músculo esquelético depende de um reflexo parassimpático hepático que conduz à libertação de uma substância hepática sensibilizadora da insulina, designada por HISS, responsável por cerca de 55% do efeito hipoglicemiante da insulina. A acção da HISS é finamente regulada pelo monóxido de azoto (NO) hepático e pelo estado prandial, aumentando no período pós-prandial imediato e diminuindo progressivamente com as horas de jejum. A secreção da HISS pode ser inibida cirúrgica ou farmacologicamente, quer por desnervação selectiva do plexo anterior hepático, quer por administração de atropina, quer por inibição do sintase do NO (NOS) hepático. O objectivo geral do trabalho apresentado nesta dissertação foi a caracterização da via de transdução de sinal que conduz à libertação da HISS. O modelo utilizado neste estudo foi o rato Wistar. A sensibilidade à insulina foi avaliada através do teste rápido de sensibilidade à insulina (RIST). A primeira hipótese de trabalho testada foi que a sequência de eventos que conduzem à secreção da HISS inicia-se com a activação do sistema parassimpático hepático seguida de activação do NOS hepático com subsequente produção de NO e activação do guanilato ciclase (GC). Observou-se que a administração de um dador de NO reverteu a resistência à insulina induzida, quer por inibição do NOS hepático, quer por antagonismo dos receptores muscarínicos com atropina. Em contraste, a resistência à insulina produzida por inibição do NOS hepático não foi revertida por administração intraportal de acetilcolina (ACh). Constatou-se que a inibição do GC hepático diminuiu a sensibilidade à insulina. Estes resultados sugerem que: a ACh libertada no fígado induz a síntese de NO hepático que conduz à libertação da HISS, que por sua vez é modulada pelo GC hepático. A libertação da HISS em resposta à insulina é regulada pelo estado prandial. Uma vez que os níveis hepáticos de glutationo (GSH) se encontram, tal como a HISS, diminuídos no estado de jejum e aumentados após a ingestão de uma refeição, testou-se a hipótese de que o GSH hepático está envolvido na secreção da HISS. Observou-se que a depleção do GSH hepático induziu resistência à insulina, comparável à obtida após inibição do NOS hepático. Estes resultados suportam a hipótese de que o GSH hepático desempenha um papel crítico na acção periférica da insulina. Considerando que, no estado de jejum, tanto os níveis de GSH hepático como os níveis de NO hepático são baixos, testou-se a hipótese de que a co-administração intraportal de um dador de GSH e de um dador de NO promove um aumento da sensibilidade à insulina no estado de jejum, devido ao restabelecimento do mecanismo da HISS. Observou-se que a administração sequencial de dadores de GSH e de NO no fígado provocou um aumento na sensibilidade à insulina, dependente da dose de dador de GSH administrada. Concluiu-se portanto que ambos, GSH e NO, são essenciais para que o mecanismo da HISS esteja completamente funcional. O GSH e o NO reagem para formar um S-nitrosotiol, o S-nitrosoglutationo (GSNO). Os resultados supra-mencionados conduziram à formulação da hipótese de que a secreção/acção da HISS depende da formação de GSNO. Observou-se que a administração intravenosa de S-nitrosotióis (RSNOs) aumentou a sensibilidade à insulina, em animais submetidos a um período de jejum, ao contrário da administração intraportal destes fármacos, o que RSNOs têm uma acção periférica, mas não hepática, na sensibilidade à insulina. Os resultados obtidos conduziram à reformulação da hipótese da HISS, sugerindo que a ingestão de uma refeição activa os nervos parassimpáticos hepáticos levando à libertação de ACh no fígado que, por sua vez activa o NOS. Simultaneamente, ocorre um aumento dos níveis de GSH hepático que reage com o NO hepático para formar um composto nitrosado, o GSNO. Este composto mimetiza a acção hipoglicemiante da HISS no músculo esquelético. SUMMARY Insulin action at the skeletal muscle depends on a hepatic parasympathetic reflex that promotes the release of a hepatic insulin sensitizing substance (HISS) from the liver, which contributes 55% to total insulin action. HISS action is modulated by hepatic nitric oxide (NO) and also by the prandial status so as to, in the immediate ostprandial state, HISS action is maximal, decreasing with the duration of fasting. HISS secretion may be inhibited by interruption of the hepatic parasympathetic reflex, achieved either by surgical denervation of the liver or by cholinergic blockade with atropine, or by prevention of hepatic NO release, using NO synthase (NOS) antagonists. The main objective of this work was to characterize the signal transduction pathways that lead to HISS secretion by the liver. Wistar rats were used and insulin sensitivity was evaluated using the rapid insulin sensitivity test (RIST). The first hypothesis tested was that the sequence of events that lead to HISS secretion starts with an increase in the hepatic parasympathetic tone, followed by the activation of hepatic NOS and subsequent triggering of guanylate cyclase (GC). We observed that insulin resistance produced either by muscarinic receptor antagonism with atropine or by hepatic NOS inhibition was reversed by the intraportal administration of an NO donor. In contrast, intraportal acetylcholine (ACh) did not restore insulin sensitivity after NOS inhibition. We also observed that GC inhibition lead to a decrease in insulin sensitivity.These results suggest that the release of ACh in the liver activates hepatic NO synthesis in order to allow HISS secretion, through a signaling pathway modulated by GC. HISS release in response to insulin is controlled by the prandial status. The second hypothesis tested was that glutathione (GSH) is involved in HISS secretion since the hepatic levels of GSH are, like HISS action, decreased in the fasted state and increased after ingestion of a meal. We observed that hepatic GSH depletion led to insulin resistance of the same magnitude of that observed after inhibition of hepatic NOS. These results support the hypothesis that hepatic GSH is crucial in peripheral insulin action. Since, in the fasted state, both hepatic GSH and NO levels are low, we tested the hypothesis that intraportal o-administration of a GSH donor and an NO donor enhances insulin sensitivity in fasted Wistar rats, by restoring HISS secretion. We observed that GSH and NO increased insulin sensitivity in a GSH dose-dependent manner. We concluded that HISS secretion requires elevated levels of both GSH and NO in the liver. GSH and NO react to form a S-nitrosothiol, S-nitrosoglutathione (GSNO). The last hypothesis tested in this work was that HISS secretion/ action depends on the formation of GSNO. We observed that intravenous administration of -nitrosothiols (RSNOs) increased insulin sensitivity in animals fasted for 24 h, in contrast with the intraportal administration of the drug. This result suggests that RSNOs enhanced insulin sensitivity through a peripheral, and not hepatic, mechanism. The results obtained led to a restructuring of the HISS hypothesis, suggesting that the ingestion of a meal triggers the hepatic parasympathetic nerves, leading to the release of Ach in the liver, which in turn activates NOS. Simultaneously, hepatic GSH levels increase and react with NO to form a nitrosated compound, GSNO. S-nitrosoglutathione mimics HISS hypoglycaemic action at the skeletal muscle.

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

The clothing industry as a globalized sector: implications for work organisation, quality of work and job content

The clothing sector in several countries is still seen, in many aspects as a traditional sector with some average characteristics, nevertheless is a very important sector in terms of labour market. Globalization and de-localization are having a strong impact in the organisation of work and in occupational careers. Very few companies are able to keep a position in the market without changes in organisation of work and workers, founding different ways to face this reality according to size, capital and position. We could find two main paths: one where companies outsource production to another territory, close and/ or dismissal the workers; other path, where companies up skilled their capacities. 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 a comparative analysis with some other European countrie

O conto - Subversão e hibridismo na estrutura tradicional

The questioning of fictional identities is central in both texts. Their structure illustrates the Bakhtinian notions of heteroglossia and dialogism and one of their main themes is the structuring and restructuring of social and personal history. Together with the use of irony and humour, the parody of social context, the use of intertextuality and metafiction, the exploration of fragment and of discontinuity, the development of self reflection and the interrogation of the author before the condition of his work, the focusing on the presence of a reader lost in the interpretation of the text, this problematisation of fictional identities places these two novels between the acts of modernism and postmodernism.
