Discovering the ways through which firms develop and maintain competitive advantage is a central research stream in management theory. The objective of this paper is to present a contribution to the discussion of the knowledge of the firm as a source of competitive advantage. The paper states that a firm's success is a consequence of its ability in the continuous development of core competencies that will sustain its competitiveness over time. Core competencies are understood as the sets of knowledge that differentiate a company strategically. The firm must discover, develop, share and update the knowledge that sustains the present and future core competencies. Knowledge management, through processes of knowledge creation and integration, is one way of doing this.

Those over sixty years of age accounted for 6.6% of the total population of Brazil in 1985, in the Federal Republic of Germany this proportion was 20.3% in 1984. As early as 1950 it had been 14.5%. This proportion will not even be reached in Brazil in the year 2000 when persons aged sixty years and older are only projected to make up 8.8% of the total population. Similarly, in 1982/84 life expectancy at birth in the Federal Republic was 70.8 years for men and 77.5 for women; in Brazil the figures for 1980/85 were, by contrast, "only" 61.0 and 66.0. Against this background it is easy to understand why the discussion concerning an ageing society with its many related medical, economic, individual and social problems has been so slow in coming into its own in Brazil. As important as a more intensive consideration of these aspects may be in Brazil at present, they are, nevertheless, only one side of the story. For a European historical demographer with a long-term perspective of three of four hundred years, the other side of the story is just as important. The life expectancy which is almost ten years lower in Brazil is not a result of the fact that no one in Brazil lives to old age. In 1981 people sixty-five years and older accounted for 34.4% of all deaths! At the same time infants accounted for only 22.1% of total mortality. They are responsible, along with the "premature" deaths among youths and adults, for the low, "average" life expectancy figure. In Europe, by contrast, these "premature" deaths no longer play much of a role. In 1982/84 more than half of the women (52.8%) in the Federal Republic of Germany lived to see their eightieth birthdays and almost half of the men (47.3%) lived to see their seventy-fifth. Our biological existence is guaranteed to an extent today that would have been unthinkable a few generations ago. Then, the classic troika of "plague, hunger and war" threatened our forefathers all the time and everywhere. The radical transition from the formerly uncertain to a present-day certain lifetime, which is the result of the repression of "plague, hunger and war", led to unexpected consequences for our living together. Our forefathers were forced to live in closely knit Gemeinschaften in the interest of physical survival and to subordinate their egoistic goals to a common value, but now these pressures have, for the most part, fallen away. Correspondingly, this much more certain EGO has taken center stage. An ever greater number of us chooses to live life as single beings: the number of marriages is lower every year; the number of divorces is on the increase; in Berlin (West) more than half (sic! 52.3%) of all households are already composed on only one person. For the last dozen years the annual number of births in the Federal Republic has been insufficient to ensure population replacement. Not a population explosion but rather the opposite, a population implosion, is our problem. Human beings do not appear to be "social animals", as was axiomatically assumed for so long. They were only forced to behave as such for as long as "plague, hunger and war" forced them to do so. When these life endangering conditions no longer exist and life becomes certain even without their being integrated into a Gemeinschaft then humans suddenly show themselves more and more to be independent single beings. It is not the percentage of the population that is over sixty or sixty-five that is decisive in this context but rather how certain adults perceive their biological lives to be, since they are the ones who organize their lives, who build communities or who are ever more often willing only to enter into means-to-an-end personal unions without lasting or close ties and mutual responsibilities. There are many signs which seem to point to a development in this direction in Brazil as well. More and more adults in Brazil are caught up in the deep-seated transition from an uncertain to a certain lifetime. A third of them die after having reached their sixty-fifth birthday. It therefore seems to me to be high time that one began to give more consideration to the other side of the story in Brazil as well. And who is more suited intensively to consider the long-term perspectives than those engaged in the public health sector in whose competence, after all, such aspects, as "life certainty", "life expectancy" and "age at death" belong?

Em estudos de acessibilidade, e nao so, sao muito uteis um tipo de estruturas que se podem obter a partir de uma rede, eventualmente multi-modal e parametrizavel: as chamadas areas de servico, as quais sao constituidas por poligonos, cada qual correspondente a uma zona situada entre um certo intervalo de custo, relativamente a uma certa feature (ponto, multiponto, etc.). Pretende-se neste estudo obter, a partir de areas de servico relativas a um universo de features, areas de servico relativas a subconjuntos dessas features. Estas tecnicas envolvem manipulacoes relativamente complexas de poligonos e podem ser generalizadas para conjuntos de conjuntos e assim sucessivamente. Convem notar que nem sempre se dispoe da rede, podendo dispor-se das referidas estruturas; eventualmente, no caso de areas de servico, sob a forma de imagens (raster) a serem convertidas para formato vectorial.

A study of Spissipes Section of Culex (Melanoconion) adults behaviour was carried out from August 1992 through December 1993 in human dominated (anthropic) environment in the Ribeira Valley, S.Paulo State, Brazil. By sampling at several sites it the dominance of Culex ribeirensis and Cx. sacchettae became evident even through a total number of ten species was recorded. Those two mosquitoes showed a clear tendency to frequent the domiciliary environment where they were caught, both indoor and outdoor, through the use of the human bait. In the outside environments, the residual patchy forests seems to display a concentration role, from which these adults spread to the open land and reach the dwellings. As their vector competence has been demonstrated through the virus isolations in natural conditions, it is advisable to pay attention to the presence of these mosquitoes in the man-made environment.

Este trabalho um contributo para o desenvolvimento de sistemas de converso de energia elica em energia elctrica em equipamentos comercialmente disponveis. Com base na recolha de dados meteorolgicos, foi caracterizada a disponibilidade da energia elica num local de instalao de um sistema de gerao de energia elctrica. A explorao dos recursos elicos pode ser caracterizada por intermdio de geradores elctricos accionados por turbinas de eixo vertical ou de eixo horizontal. O sistema de gerao projectado utiliza como gerador elctrico a mquina assncrona de rotor em curto-circuito accionada por uma turbina de eixo vertical do tipo Savonius. No que respeita a converso electromecnica de energia, para realizar a excitao do gerador de induo e o controlo da potncia entregue rede, foi utilizado um conversor electrnico industrial do tipo regenerativo dedicado a accionamentos de velocidade varivel. A estratgia de controlo utilizada, nos modelos desenvolvidos para simulao do sistema de gerao proposto, utiliza a tcnica de controlo vectorial de orientao de campo para realizar o controlo do binrio do gerador de induo, colocando-o em modo de frenagem, atravs do qual recolhida energia elctrica. Tendo em vista a comprovao experimental do desempenho do sistema proposto, foi realizado em laboratrio um prottipo. Neste prottipo a turbina Savonius simulada por um accionamento mecnico constitudo por um conjunto variador de velocidade - mquina sncrona de magnetos permanentes. O controlo do sistema feito por intermdio de um processador digital de sinal (DSP). O DSP impe a dinmica desejada para turbina ao seu simulador electromecnico, faz o tratamento dos dados adquiridos no sistema gerador, implementa o seu controlo e estabelece a interface humano-mquina. O modelo terico proposto para o sistema de gerao e a estratgia de controlo adoptada so validados por comparao entre resultados de simulao numrica e os correspondentes resultados experimentais.

Environmental tobacco smoke (ETS) is recognized as an occupational hazard in the hospitality industry. Although Portuguese legislation banned smoking in most indoor public spaces, it is still allowed in some restaurants/bars, representing a potential risk to the workers health, particularly for chronic respiratory diseases. The aims of this work were to characterize biomarkers of early genetic effects and to disclose proteomic signatures associated to occupational exposure to ETS and with potential to predict respiratory diseases development. A detailed lifestyle survey and clinical evaluation (including spirometry) were performed in 81 workers from Lisbon restaurants. ETS exposure was assessed through the level of PM 2.5 in indoor air and the urinary level of cotinine. The plasma samples were immunodepleted and analysed by 2D-SDSPAGE followed by in-gel digestion and LC-MS/MS. DNA lesions and chromosome damage were analysed innlymphocytes and in exfoliated buccal cells from 19 cigarette smokers, 29 involuntary smokers, and 33 non-smokers not exposed to tobacco smoke. Also, the DNA repair capacity was evaluated using an ex vivo challenge comet assay with an alkylating agent (EMS). All workers were considered healthy and recorded normal lung function. Interestingly, following 2D-DIGE-MS (MALDI-TOF/TOF), 61 plasma proteins were found differentially expressed in ETS-exposed subjects, including 38 involved in metabolism, acute-phase respiratory inflammation, and immune or vascular functions. On the other hand, the involuntary smokers showed neither an increased level of DNA/chromosome damage on lymphocytes nor an increased number of micronuclei in buccal cells, when compared to non-exposed non-smokers. Noteworthy, lymphocytes challenge with EMS resulted in a significantly lower level of DNA breaks in ETS-exposed as compared to non-exposed workers (P<0.0001) suggestive of an adaptive response elicited by the previous exposure to low levels of ETS. Overall, changes in proteome may be promising early biomarkers of exposure to ETS. Likewise, alterations of the DNA repair competence observed upon ETS exposure deserves to be further understood.

A problemtica da insero profissional dos novos professores tem sido largamente estudada sob vrias perspetivas das quais destacamos, as dificuldades enfrentadas no incio do seu desempenho como docentes (Alen y Sardi, 2009) Krichesky y Merodo (2009), o vinculo entre insero e identidade profissional (Martineau y Portelance, 2005), o desenvolvimento da competncia tica nos novos professores (St. Vincent 2011) e as trajetrias de emprego, entre outras.Os resultados destas pesquisas tm revelado o tipo de problemas enfrentados pelos novos professores entrada na carreira docente e confirmado que nem todos os percursos se iniciam de modo tranquilo e sereno. esta a problemtica que serve de base ao objeto de estudo desta dissertao, pretendendo-se mais precisamente, centrar a nossa pesquisa no percurso profissional de seis professores diplomados pela Escola Superior de Educao de Lisboa h dois anos. O objetivo geral do estudo , assim, descrever e compreender o desenvolvimento profissional desses professores, identificar as dimenses mais relevantes, os fatores que o condicionam e os contextos que o limitam ou facilitam. Tendo em conta o objeto de estudo identificaram-se as seguintes questes: 1) Quais as implicaes da formao inicial no desempenho da profisso? 2) Quais as principais dificuldades / problemas com que se defrontaram os novos professores na insero na profisso?; 3) Como atuam os professores principiantes?; O que mudam nas suas prticas, o que perdura?; 4) Como se incrementa o sentimento de pertena ao novo grupo profissional?; 5) Quais as particularidades dos contextos de trabalho em que estes professores se encontram integrados que se revelam facilitadoras e/ou constrangedoras da sua insero profissional? Para o efeito recorremos a uma metodologia qualitativa, e privilegimos como tcnica de recolha de dados a entrevista semiestruturada. Para o tratamento dos dados sustentmo-nos na anlise de contedo seguindo os passos recomendados para a anlise de contedo (Bardin, 2009). Os resultados do estudo permitiram identificar os constrangimentos experimentados por estes professores entrada da profisso, assim como os modos como os ultrapassaram. Destes, destacam-se dificuldades relacionadas com a falta de autonomia, com aspetos de natureza metodolgica, ao nvel da organizao e desenvolvimento curricular e de relacionamento com os elementos da direo das instituies nos contextos de trabalho.Abstract The issue of employability of new teachers has been widely studied from various perspectives. Research has revealed the sort of problems faced by new teachers at the beginning of their career. It confirms that frequently it is not a peaceful and serene start. We highlight the following difficulties: the link between integration and professional identity (Alen y Sardi, 2009; Krichesky y Merodo, 2009), the development of ethical competence in new teachers (y Portelance Martineau, 2005), and the professional path (St. Vincent 2011). This is the hypothesis explored in this thesis. Specifically, we focus our research on the career of six graduate teachers by the Lisbon School of Education. The main objective is to describe and understand the professional development of these teachers. For that we identify the most relevant dimensions, the factors that constrain and contexts that limit or facilitate their development. A qualitative methodology was used throughout the study. Semi structured interviews were the main data collection process. Data treatment followed the recommended framework for content analysis (Bardin, 2009). The following research questions were put forward: 1) What are the impacts of base level of knowledge in the professional performance? 2) What are the main difficulties / problems that new teachers face? 3) How do novice teachers perform? What changes in their methods, what endures? 4) What increases the feeling of belonging to the new professional group? 5) What are the peculiarities of work contexts that act as facilitators and/or barriers to professional acceptance? The results allowed identifying the constraints experienced by teachers at the beginning of their careers, and the ways to surpass them. We highlight the difficulties related to: lack of autonomy; methodologies; curricular organization and development; and the relationship with the directors at their workplace.
