Dada a lacuna nos ensaios promovidos pela RELACRE - Associação de Laboratórios Acreditados de Portugal, no domínio do ar ambiente de trabalho, durante o mes de Julho de 2008 as entidades A. Ramalhão -Consultoria, Gestão e Serviços Lda, Cinfu - Centro Profissional da Indústria de Fundição e INETI - Instituto Nacional de Engenharia Tecnologia e Inovação, I.P. executaram um ensaio de comparação entre laboratórios nesse domínio intitulado "Determinação de partículas totais e respiráveis em suspensão no ambiente de trabalho". Este ensaio teve como objectivo a determinação da concentração de partículas respiráveis e totais pelos laboratórios participantes, de modo a contribuir para a melhoria do desempenho e da qualidade, com vista ao cumprimento de alguns requisitos exigidos a metodologias de amostragem acreditadas. Para o efeito, cada participante efectuou a amostragem baseando-se em metodologias NIOSH - National Institute for Occupational Safety and Health e determinou a concentração de poeiras respiráveis e totais na perspectiva da avaliação da exposição profissional a agentes químicos utilizando os valores limite estabelecidos na Norma Portuguesa 1796 (2007). O presente artigo apresenta a metodologia utilizada na colheita da amostra, na determinação das concentrações, os resultados obtidos e principais conclusões.

Com vista ao cumprimento de alguns requisitos exigidos a metodologias de amostragem acreditadas e após a execução do ensaio de comparação entre laboratórios para a determinação de partículas totais e respiráveis em suspensão no ambiente de trabalho, tornou-se necessário proceder ao calculo da incerteza. A metodologia de calculo da incerteza da medição, bem como o ensaio foram da responsabilidade das entidades A. Ramalhão - Consultoria, Gestão e Serviços Lda, Cinfu - Centro Profissional da Indústria de Fundição e INETI - Instituto Nacional de Engenharia Tecnologia e Inovação, I.P. Sendo para os laboratórios participantes a garantia da qualidade dos seus resultados primordial, o calculo da incerteza apresenta-se como factor determinante. Neste artigo são apresentadas as fontes de incerteza consideradas como relevantes e a metodologia para o calculo da incerteza de medição expandida associada.

In recent years, audiovisual production and consumption have undergone quite significant changes. New platforms, new technologies, new habits are contribut­ing to greater interaction and, currently, an intensification of niche content audience formation is observed. Based on a case developed in an experimental way, the webseries #E_VC? and another case produced by the Gloob channel (Globo Studios) we seek to exemplify how some strategies previously adopted in productions made for broadcasting on the internet were also adopted in television productions. This “hybridization” has been quite re­current and shows a certain market trend in the adoption of these languages and technologies, promoting virtual and face-to-face interactions to their audiences. Top­ics such as transmedia, virtual environments, forms of interaction and audiovisual consumer experience have been increasingly discussed in this light. TV channels and media conglomerates have turned their attention to on-demand au­diovisual consumption environments, as well as other platforms and websites that provide new information (not only those that are placed in the script and history of audiovisual content) but also experiences in these complementary environments, that is, the production of audiovisual content and design concepts are being worked on together, focusing on their audiences and how this relationship can be approached from the personal interests of this audience. Algorithms, manipulation of information increasingly faster from large databases are of great value to understand communi­cation contexts and changes in this market.

This study examined differences in personality features and antisocial behaviour of institutionalized female and male juvenile offenders. Sixty juvenile delinquents (30 female) were evaluated in order to obtain antisocial personality traits, measures of delinquent disposition, as well as measures of frequency and diversity of delinquent behaviour. Contrary to what was expected and reported in the literature, the results showed no gender differences in terms of psychopathic features, nor disposition to delinquent behaviour, but a gender effect was found in relation to the frequency and diversity of antisocial behaviours, with a male dominance in both cases. We advance with possible explanations for the obtained results within the context of the limitations of the study, and identify cues that may contribute to further researches on gender differences in juvenile delinquency, still scarce in Portugal.

Globalization of the economy has revived the interest on the theme of internationalization of companies. There may be several motives for a company to expand its markets, but whatever they are, the success of the process depends on specific and characteristic assets that the company possesses and on their capacity to provide competitive muscle. Among other strategic choices, the development of innovation capabilities is a possible path to provide the firm with knowledge and organizational assets that confer it a competitive edge. Knowledge assets are increasingly important in an interconnected and open world market, where traditional localized competitive factors, such as low labour costs, are rapidly losing appeal as drivers of sustainable and continued value creation. In a highly competitive international market, innovation and internationalization seem to be themes that are intrinsically related to each other, in the sense that knowledge and innovation capabilities seem to be a necessary prerequisite to an internationalization process. However, per se, innovation capabilities, and the assets behind it, may not be enough to a successful endeavour. In the absence of privileged, localized knowledge of the national market, strategic considerations are of paramount importance to the internationalization process. Strategic actions are important, not only at the planning stage but also at the implementation stage. It is argued in this paper that these aspects, knowledge, innovation and strategy, are crucial to understand actual internationalization processes and dynamics. This paper intends to examine the above concepts and the links between these factors and their effects on business performance and competitiveness and comprehend internationalization processes. It provides a comprehensive review on the literature regarding the possible connections between the three concepts and it identifies the main ideas and variables that have been suggested and are being regarded. It provides a useful synthesis and it suggests f
