A união faz a força: Cooperação como resposta aos desafios organizacionais: Contrato psicológico e compromisso organizacional

Dissertação de Mestrado em Psicologia Social e das Organizações apresentada ao ISPA - Instituto UniversitárioNeste trabalho pretende-se estudar a cooperação e a sua relação com o compromisso e com o contracto psicológico no contexto organizacional. A literatura sobre a relação destas variáveis ainda é escassa e, por isso, é importante delinear a relevância e o impacto destas variáveis. Estamos perante um estudo com uma amostra de 136 participantes, transversal, exploratório e explanatório. Os resultados mostraram que a hipótese 1 confirma-se, ou seja, o compromisso tem um impacto significativo na cooperação. No caso da cooperação, os resultados mostraram que a hipótese 2 não se confirma, isto é, o contracto psicológico não tem impacto significativo na cooperação. Uma terceira hipótese foi formulada: o contracto psicológico tem um efeito moderador na relação do compromisso com a cooperação. Esta hipótese não foi confirmada.ABSTRACT: The aim of this research was to study the relation between cooperation with commitment and psychological contract in the organizational context. The literature referring to this subject is still scarce and, therefore, it is important to outline the relevance and impact of these variables. This investigation it is an exploratory and explanatory, cross-sectional study and it has 136 participants. The results showed that the first hypothesis was confirmed, i. e., the commitment as a significant impact on cooperation. The data also presented lack of support for both hypotheses 2 and 3. Thus, the hypothesis 2 was not confirmed; hence, the psychological contract has no significant impact on cooperation. A third hypothesis was formulated: the psychological contract has a moderating effect on the relationship of commitment to cooperation. This hypothesis was not confirmed

PAIN with and without PAR: variants for third-spin assisted heteronuclear polarization transfer

In this article, we describe third-spin assisted heteronuclear recoupling experiments, which play an increasingly important role in measuring long-range heteronuclear couplings, in particular N-15-C-13, in proteins. In the proton-assisted insensitive nuclei cross polarization (PAIN-CP) experiment (de PaA C-13) polarization transfer while simultaneously minimizing homonuclear (e.g.C-13 -> C-13) transfer (PAIN without PAR). This minimization of homonuclear polarization transfer is based on the principle of the resonant second-order transfer (RESORT) recoupling scheme where the passive proton spins are irradiated by a phase-alternating sequence and the modulation frequency is matched to an integer multiple of the spinning frequency. The similarities and differences between the PAIN-CP and this het-RESORT experiment are discussed here

Communist Revolution and Peasant Mobilisation in the Hinterland of North China: The Early Years

This chapter examines the depiction by populism in the domain of 'popular culture' of what purports to be its non-capitalist/non-socialist alternative: in short, the socio-economic and political structure of its 'imaginary' as this involves a symptomatic opposition between the utopic and dystopic. Using the pseudonym of Ivan Kremnev, the Russian neo-populist theoretician A. V. Chayanov wrote the utopian fiction The Journey of My Brother Alexei to the Land of Peasant Utopia. Accordingly, the utopic vision of Chayanov entails traversing time but not space; the protagonists in his narrative are projected forward into a future within the same demarcated space. Much of the populist discourse which structures the agrarian myth is present in the films of Frank Capra, who directed not only Lost Horizon but also Mr Deeds Goes to Town (1936), Mr Smith Goes to Washington (1939) and t's a Wonderful Life (1946)
