    Knowledge along with the human resource is the most valued asset of a company. Knowledge management has received much interested by researchers since it is a determinant key to perform efficiently. Due to society‚Äôs evolution, namely technological tools, on personal and professional routines, literature has improved in that sense and concluded that it can raise knowledge sharing facilitating the way employees work as well as the access to information, improving the performance. However, it is not known much about the interaction of this variables on team level. In this study, we explored how technology influence team performance through knowledge sharing and application considering sense making leadership, meaning, how the relationship above works if there was a promotion of discussion among team members. We tested our model in a sample of 54 teams (210 individuals). The results showed that there is a significant relationship between technology and knowledge sharing and hence team performance. Knowledge application does not have a direct implication, despite its indirectly impact on team‚Äôs performance. As a moderator, sense making leadership has a crucial role in the relationships described above in a way that can work as a substitute of technology, enhancing knowledge sharing and application when IT tools are not available. Therefore, regarding practical implications of this study, since society is continuously improving being more technological over time, it is important to organizations to keep the investment on it, never forgetting the way it is managed into teams.O conhecimento em paralelo com os recursos humanos s√£o o maior ativo numa empresa. A gest√£o do conhecimento tem recebido a aten√ß√£o dos investigadores, dado que poder√° ser a chave para um desempenho eficiente. Tendo a tecnologia sofrido uma consider√°vel evolu√ß√£o, a n√≠vel pessoal e profissional, a literatura tem acompanhado este progresso e concluiu que a partilha do conhecimento √© proporcionada pela tecnologia disponibilizada, que facilitar√° o m√©todo de trabalho e o acesso √† informa√ß√£o melhorando o desempenho. Contudo, ao n√≠vel da equipa, estas din√Ęmicas n√£o t√™m sido aprofundadas. Ao longo do trabalho, o modelo explorado permite averiguar de que forma a tecnologia influencia o desempenho da equipa atrav√©s da partilha e aplica√ß√£o do conhecimento, tendo em conta a promo√ß√£o da discuss√£o das variadas situa√ß√Ķes na equipa. O modelo foi testado numa amostra de 54 equipas (210 trabalhadores). Os resultados revelaram uma rela√ß√£o significativa entre a tecnologia e a partilha do conhecimento e, consequentemente, no desempenho da equipa. A aplica√ß√£o do conhecimento tem um impacto indireto no desempenho da mesma. A promo√ß√£o de sense making pelo l√≠der tem um papel fundamental nas rela√ß√Ķes acima descritas, na medida em que funcionar√° como substituto da tecnologia, promovendo a transfer√™ncia e uso do conhecimento quando este tipo de recurso n√£o est√° dispon√≠vel. Cada vez mais, a tecnologia faz parte das rotinas da sociedade, pelo que, √© importante que as empresas continuem a investir nesta √°rea, nunca esquecendo de que √© importante o modo como √© utilizada e gerida ao n√≠vel das equipas

    Tese de mestrado integrado em Psicologia (Psicologia dos Recursos Humanos do Trabalho e das Organiza√ß√Ķes), apresentada √† Universidade de Lisboa atrav√©s da Faculdade de Psicologia e de Ci√™ncias da Educa√ß√£o, 2008Assumindo como enquadramento te√≥rico basilar a literatura no √Ęmbito do Contrato Psicol√≥gico, o presente estudo debru√ßa-se sobre as rela√ß√Ķes tripartidas de emprego contingente, as quais envolvem o colaborador contingente, a ag√™ncia empregadora e a organiza√ß√£o cliente, na qual este colaborador desempenha as suas fun√ß√Ķes. A presente investiga√ß√£o visa explorar, empiricamente, o contrato psicol√≥gico dos colaboradores contingentes, partindo da premissa de que a percep√ß√£o de cumprimento das obriga√ß√Ķes da ag√™ncia √© influenciada pela percep√ß√£o de cumprimento das obriga√ß√Ķes do cliente, pela atractividade deste mesmo cliente, pela inseguran√ßa no trabalho e pela empregabilidade. As hip√≥teses colocadas foram testadas com base em question√°rios respondidos por colaboradores de quatro ag√™ncias, localizadas em Portugal. A amostra abrangia oitenta e oito colaboradores diferenciados que trabalhavam em organiza√ß√Ķes clientes, cujas actividades se enquadravam no sector financeiro e no sector das tecnologias de informa√ß√£o. Os resultados obtidos sugerem que a percep√ß√£o de cumprimento das obriga√ß√Ķes da ag√™ncia √© influenciada positivamente pela percep√ß√£o de cumprimento das obriga√ß√Ķes do cliente. A segunda hip√≥tese apresentada n√£o foi corroborada, na medida em que n√£o se verificou uma influ√™ncia significativa por parte da atractividade da organiza√ß√£o cliente, na percep√ß√£o de cumprimento das obriga√ß√Ķes da ag√™ncia. Adicionalmente, os resultados demonstraram que a percep√ß√£o de cumprimento das obriga√ß√Ķes da ag√™ncia √© influenciada negativamente pela percep√ß√£o de inseguran√ßa no trabalho, o que suporta a terceira hip√≥tese em an√°lise. No que concerne √† quarta hip√≥tese, os resultados n√£o a suportaram, n√£o se constatando uma influ√™ncia significativa da percep√ß√£o de empregabilidade, na percep√ß√£o de cumprimento das obriga√ß√Ķes da ag√™ncia. Numa sec√ß√£o final, os resultados mencionados s√£o discutidos, sendo apresentadas as implDrawing on psychological contract literature, the present study examines the emerging contingent employment relationships, which involve the contingent employee, the employing agency and the client organization on whose premises the contingent employee works. This investigation will empirically explore the psychological contracts of contingent employees, anticipating that the perceived fulfilment of agency's obligations is influenced by the perceived fulfilment of client's obligations, by client organization attractiveness, by job insecurity and by employability. We tested our hypotheses using a survey collected from employees working in four Portuguese agencies. The sample included eighty-eight white-collared employees, working for client organizations in the financial and information technologies sectors. The results suggest that the perceived fulfilment of agency's obligations is positively influenced by the perceived fulfilment of client organization's obligations. Our second hypothesis was not supported by the results, meaning that perceived client organization attractiveness did not significantly influence the perceived fulfilment of agency's obligations. Furthermore, as expected, we found that the fulfilment of agency's perceived obligations is negatively influenced by the perception of job insecurity. Concerning our fourth hypothesis, it was not supported by the results, meaning that the perceived fulfilment of agency's obligations is not influenced by the perception of employability. In a final section, the obtained results are discussed and their possible implications on human resource practices for contingent employees are presented. There will also be suggested some new paths for future investigations

    Hybrid sol-gel coatings: smart and green materials for corrosion mitigation

    Corrosion degradation of materials and metallic structures is one of the major issues that give rise to depreciation of assets, causing great financial outlays in their recovery and or prevention. Therefore, the development of active corrosion protection systems for metallic substrates is an issue of prime importance. The promising properties and wide application range of hybrid sol-gel-derived polymers have attracted significant attention over recent decades. The combination of organic polymers and inorganic materials in a single phase provides exceptional possibilities to tailor electrical, optical, anticorrosive, and mechanical properties for diverse applications. This unlimited design concept has led to the development of hybrid coatings for several applications, such as transparent plastics, glasses, and metals to prevent these substrates from permeation, mechanical abrasion, and corrosion, or even for decorative functions. Nevertheless, the development of new hybrid products requires a basic understanding of the fundamental chemistry, as well as of the parameters that influence the processing techniques, which will briefly be discussed. Additionally, this review will also summarize and discuss the most promising sol-gel coatings for corrosion protection of steel, aluminium, and their alloys conducted at an academic level.info:eu-repo/semantics/publishedVersio
