Into a new phase of the research on restructuring of work in the knowledge society: the Third WORKS General Assembly in Sofia (Bulgaria)

The WORKS Project started two years ago (2005), involving the efforts of research institutes of 13 European countries with the main purpose of improving the understanding of the major changes in work in the knowledge-based society, taking account both of global forces and the regional diversity within Europe. This research meeting in Sofia (Bulgaria) aimed to present synthetically the massive amount of data collected in the case studies (occupational and organisational) and with the quantitative research during last year.

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.

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).

The role of detoxification in the mosquito Anopheles gambiae response to Plasmodium infection

Rute C. Félix PALAVRAS-CHAVE: Malária, mosquito vector, Anopheles gambiae, parasita, Plasmodium berghei, infecção, enzimas de detoxificação, citocromos P450, tubulinas A malária, uma das doenças mais devastadoras que ocorrem em África é causada por um parasita do género Plasmodium e é transmitida aos humanos por mosquitos vectores do género Anopheles durante a refeição de sangue. Apesar da resposta do mosquito à infecção por Plasmodium ter vindo a ser intensamente estudada nos últimos anos, as interacções entre o mosquito vector e o parasita são muito complexas e, estão longe de serem completamente compreendidas. Este estudo tem como objectivo principal contribuir para o conhecimento da resposta do mosquito à infecção por Plasmodium, focando-se no papel das enzimas de detoxificação. Para atingir este objectivo realizouse uma análise transcriptómica com microarrays, com o intuito de identificar alterações de transcrição de enzimas de detoxificação no mosquito Anopheles gambiae em resposta à infecção por Plasmodium. Esta análise permitiu identificar alterações na expressão de 254 genes de destoxificação no estômago e corpo gordo de A. gambiae durante a invasão do intestino médio pelos oocinetos e durante a libertação dos esporozoítos do oocisto. Os resultados mostraram que a invasão do intestino médio pelos oocinetos causou alterações num maior número de genes em ambos os tecidos estudados, sendo o intestino médio do mosquito o tecido mais afectado nas duas fases da infecção do parasita. De todos os genes de destoxificação com expressão alterada, as tubulinas e os citocromos P450 destacaram-se e foram escolhidos para continuar o estudo. As tubulinas foram seleccionadas porque estão associadas à invasão do epitélio do intestino médio e a sua função na resposta à invasão do Plasmodium ainda não está bem definida. Os citocromos P450 foram seleccionados porque já foram descritos como tendo a expressão alterada em resposta ao Plasmodium e a outras infecções. Para identificar e caracterizar o papel das tubulinas durante a infecção pelo parasita e a sua possível associação com os citocromos P450 foi utilizado o silenciamento génico por RNA de interferência e a injecção de inibidores químicos de tubulinas. O silenciamento e co-silenciamento das tubulinas causaram um aumento da taxa e intensidade da infecção. No entanto, apesar de o aumento ser consistente não foi significativo. Por outro lado, a injecção de paclitaxel, um inibidor de tubulinas, aumentou significativamente a taxa e intensidade da infecção, fortalecendo a hipótese do envolvimento das tubulinas na resposta à infecção por Plasmodium. Este trabalho também mostrou que o co-silenciamento da tubulina A e tubulina B e a injecção do inibidor de tubulinas colchicine causam alterações significativas na expressão da CYP6Z2, sendo este proposto como um possível elo de ligação entre as tubulinas e os citocromos P450. Finalmente, uma análise comparativa foi realizada para estudar as regiões promotoras dos citocromos P450: CYP6M2 e o CYP6Z1. Este estudo obteve novos dados sobre compostos que activam estes citocromos e quais os possíveis factores de transcrição envolvidos. Dos diferentes estímulos utilizados, a exposição a insecticidas e a bactérias foram os que mais afectaram estes citocromos. O conjunto total das diferentes abordagens utilizadas neste trabalho contribuiu para aumentar o conhecimento do papel das enzimas de destoxificação durante a passagem do parasita da malária pelo mosquito vector.

Fruta com cheiro: The implementation of a new brand of fruit in the Portuguese market

‘’Fruta com Cheiro’’ is an idea for a new brand of fruit that would be introduced in the Portuguese market that would differentiate itself from the brands already in the market and from other non-branded fruit producers. In order to prove that the idea was valid and would have a place in the market, two methods of exploratory research were used – in-depth interviews and focus groups – to understand attitudes and behaviors regarding fruit selection and purchase and also people’s perceptions to ‘’Fruta com Cheiro’’. After these two steps, several considerations were made in relation to preliminary marketing aspects such as brand creation and positioning. There was also a final remark on the fact that this thesis is not a business plan and its purpose was to show how viable would the project be.

Portuguese commercial banking: An assessment of competition in the 1960-2013 period

Strong consolidation is one of the most evident developments of banking markets around the world in recent decades. This change is raising questions on how and to what an extent competition is affected by the expansion of the largest banks. The aim of the present study is to measure the degree of competition in the Portuguese commercial banking market in the long-run, during the period ranging from1960 to 2013, by using the non-structural model developed by Panzar and Rosse. The main findings are that the Portuguese banking system, despite the legal restrictions in place, operated mostly in a market with some degree of competition and, at some points in time, presented some interesting competitive features. More recently, it has evolved into functioning as a cartel.

Historic and recent occurrences of pinnipeds in the Archipelago of the Azores

The Archipelago of the Azores (Portugal) is located between 378 and 418N and 258 and 318W and crosses the Mid-Atlantic Ridge. It is the most isolated archipelago in the Atlantic, situated 1600 km west of mainland Portugal and 3500 km from the eastern coast of the United States of America. At present, the only population of seals occurring in the Portuguese territory is found on Desertas Islands, Archipelago of Madeira, where a colony of 24 Mediterranean monk seals, Monachus monachus (Hermann, 1779), still persists (Pires and Neves 2001). Nonetheless, historical accounts reported by Frutuoso (1983) dating from the early to late 1500s mention sightings of ‘‘sea wolves’’ (the old Portuguese folk term for the Mediterranean monk seal) at several sites along the Azorean Island of Santa Maria. Little is known about the occurrence of monk seals in this area over the past five centuries, but the species certainly did not escape deliberate killing by the first settlers. While the early monk seal reports by Frutuoso (1983) are the only reports referring to the presence of colonies of seals in the Azores, more recently several sightings and strandings of vagrant seals of other species have been noted.
