The visual image in Epiphanic Short History

The visual image is a fundamental component of epiphany, stressing its immediacy and vividness, corresponding to the enargeia of the traditional ekphrasis and also playing with cultural and social meanings. Morris Beja in his seminal book Epiphany in the Modern Novel, draws our attention to the distinction made by Joyce between the epiphany originated in a common object, in a discourse or gesture and the one arising in “a memorable phase of the mind itself”. This type materializes in the “dream-epiphany” and in the epiphany based in memory. On the other hand, Robert Langbaum in his study of the epiphanic mode, suggests that the category of “visionary epiphany” could account for the modern effect of an internally glowing vision like Blake’s “The Tyger”, which projects the vitality of a real tyger. The short story, whose length renders it a fitting genre for the use of different types of epiphany, has dealt with the impact of the visual image in this technique, to convey different effects and different aesthetic aims. This paper will present some examples of this occurrence in short stories of authors in whose work epiphany is a fundamental concept and literary technique: Walter Pater, Joseph Conrad, K. Mansfield, Clarice Lispector. Pater’s “imaginary portraits” concentrate on “priviledged moments” of the lives of the characters depicting their impressions through pictorial language; Conrad tries to show “moments of awakening” that can be remembered by the eye; Mansfield suggests that epiphany, the “glimpse”, should replace plot as an internal ordering principle of her impressionist short-stories; in C. Lispector the visualization of some situations is so aggressive that it causes nausea and a radical revelation on the protagonist’s.

Ligand K-edge X-ray absorption spectroscopy and DFT calculations on [Fe3S4]0,+ clusters: delocalization, redox, and effect of the protein environment

Ligand K-edge XAS of an [Fe3S4]0 model complex is reported. The pre-edge can be resolved into contributions from the í2Ssulfide, í3Ssulfide, and Sthiolate ligands. The average ligand-metal bond covalencies obtained from these pre-edges are further distributed between Fe3+ and Fe2.5+ components using DFT calculations. The bridging ligand covalency in the [Fe2S2]+ subsite of the [Fe3S4]0 cluster is found to be significantly lower than its value in a reduced [Fe2S2] cluster (38% vs 61%, respectively). This lowered bridging ligand covalency reduces the superexchange coupling parameter J relative to its value in a reduced [Fe2S2]+ site (-146 cm-1 vs -360 cm-1, respectively). This decrease in J, along with estimates of the double exchange parameter B and vibronic coupling parameter ì2/k-, leads to an S ) 2 delocalized ground state in the [Fe3S4]0 cluster. The S K-edge XAS of the protein ferredoxin II (Fd II) from the D. gigas active site shows a decrease in covalency compared to the model complex, in the same oxidation state, which correlates with the number of H-bonding interactions to specific sulfur ligands present in the active site. The changes in ligand-metal bond covalencies upon redox compared with DFT calculations indicate that the redox reaction involves a two-electron change (one-electron ionization plus a spin change of a second electron) with significant electronic relaxation. The presence of the redox inactive Fe3+ center is found to decrease the barrier of the redox process in the [Fe3S4] cluster due to its strong antiferromagnetic coupling with the redox active Fe2S2 subsite.

Os enfermeiros e as dimensões motivacionais : estudo não experimental, descritivo, analítico e transversal, baseado na técnica de inquérito

RESUMO - A profissão de enfermagem é definida por Virgínia Henderson (1966), como tendo por objeto "ajudar o indivíduo, saudável ou doente, na execução das atividades que contribuem para conservar a sua saúde ou a sua recuperação, de tal maneira, devendo desempenhar esta função no sentido de tornar o indivíduo o mais independente possível, ou seja, a alcançar a sua anterior independência". A atenção à saúde ao longo da história da humanidade vem sendo desenvolvida de muitos modos e por diversos atores sociais. O trabalho em saúde é essencial para a vida humana e envolve atividades realizadas por profissionais e equipas multidisciplinares que dominam os conhecimentos e técnicas essenciais para assistir o indivíduo com problemas de saúde ou em risco de adoecer, em atividades de investigação, de prevenção, curativo e de reabilitação. À Enfermagem tal como a outras profissões, são cada vez mais exigidos requisitos de eficiência, eficácia e polivalência na sua atividade, tendo a motivação um papel fundamental na atitude, postura e desempenho do profissional. Este trabalho descreve o estudo da motivação profissional, numa população de enfermeiros portugueses numa instituição privada. A versão adaptada de um inquérito como instrumento de autopreenchimento representa vários construtos implicados no processo motivacional, em contexto profissional. Pretendo com este estudo identificar a dimensão da motivação mais relevantes no processo motivacional dos enfermeiros, assim como as suas variações face a variáveis de características pessoais, profissionais e institucionais. A partir dos resultados obtidos pretendo ainda apresentar sugestões de maneira a oferecer oportunidade de transformação do seu ambiente organizacional em instituições similares.
