    Unidade de Monitorização em Indicadores de Saúde - UMISAbstract - To understand the importance that nurses assign to simulation in the development of non-technical skills in cardiac arrest event in pre-hospital setting. Background Nursing is projected in the future, developing a patient centred approach consistent with the values, needs and desires of patients, considering process of care as a complex intervention. Simulation based on scenarios is an opportunity to recreate this complexity in a virtual way, to develop the non-technical skills. Methods This study uses an inductive, interpretative and constructivist qualitative research. 7 nurses were interviewed. It was developed a thematic analysis content. Results Three themes were identified: Simulation scenarios in pre-hospital emergencies; The acquisition of knowledge to skills development and Construction of the virtual from the real Conclusions The interviewed nurses present weakness of knowledge about simulation types. Debriefing is relevant to the learning skills: critical thinking. thinking, clinical judgement and decision making.Resumo - Compreender a importância que os enfermeiros atribuem à simulação no desenvolvimento de competências não técnicas no evento paragem cardíaca em ambiente préhospitalar. Enquadramento A enfermagem é projetada no futuro, desenvolvendo uma abordagem centrada na pessoa consistente com a valorização de valores, necessidades e desejos destes, considerando o processo de cuidados como intervenção complexa. A simulação baseada em cenários é uma oportunidade para recriar essa complexidade de forma virtual, no desenvolvimento de competências não-técnicas. Metodologia Este estudo utiliza uma pesquisa qualitativa indutiva, interpretativa e construtivista. Foram entrevistados 7 enfermeiros. Foi desenvolvida análise de conteúdo temática. Resultados Foram identificados três temas: cenários de simulação em emergências pré-hospitalares; A aquisição de conhecimento para o desenvolvimento de habilidades e Construção do virtual a partir do real. Conclusões Os enfermeiros entrevistados apresentam conhecimentos a melhorar em relação aos tipos de simulação. Consideram o Debriefing relevante para as habilidades de aprendizagem: pensamento crítico, julgamento clínico e a tomada de decisão.Resumen - Comprender la importancia que los enfermeros atribuyen a la simulación en el desarrollo de competencias no técnicas en el evento paro cardíaco en ambiente prehospitalario.

    The Role of Fermions in Bubble Nucleation

    We present a study of the role of fermions in the decay of metastable states of a scalar field via bubble nucleation. We analyze both one and three-dimensional systems by using a gradient expansion for the calculation of the fermionic determinant. The results of the one-dimensional case are compared to the exact results of previous work.Comment: 15 pages, revtex, 9 figure

    Geometric Phase for Fermionic Quasiparticles Scattering by Disgyration in Superfluids

    Full text link
    We consider a Volovik's analog model for description of a topological defects in a superfluid and we investigate the scattering of quasiparticles in this background. The analog of the gravitational Aharonov-Bohm in this system is found. An analysis of this problem employing loop variables is considered and corroborates for the existence of the Aharonov-Bohm effect in this system. The results presented here may be used to study the Aharonov-Bohm effect in superconductors.Comment: 7 pages, to appear in Europhys. Let

    Semiclassical Series from Path Integrals

    We derive the semiclassical series for the partition function in Quantum Statistical Mechanics (QSM) from its path integral representation. Each term of the series is obtained explicitly from the (real) minima of the classical action. The method yields a simple derivation of the exact result for the harmonic oscillator, and an accurate estimate of ground-state energy and specific heat for a single-well quartic anharmonic oscillator. As QSM can be regarded as finite temperature field theory at a point, we make use of Feynman diagrams to illustrate the non-perturbative character of the series: it contains all powers of \hbar and graphs with any number of loops; the usual perturbative series corresponds to a subset of the diagrams of the semiclassical series. We comment on the application of our results to other potentials, to correlation functions and to field theories in higher dimensions.Comment: 18 pages, 4 figures. References update
