Magnetic structure, dipole reversals, and 1/f noise in resistive MHD spherical dynamos

A parametric study of the magnetic dipole behavior in resistive incompressible magnetohydrodynamics inside a rotating sphere is performed, using direct numerical simulations and considering Reynolds and Ekman numbers as controlling parameters. The tendency is to obtain geodynamolike magnetic dipole reversal regimes for sufficiently small Ekman and large Reynolds numbers. The typical dipole latitude obtained in the reversal regime is around 40-(with respect to the rotation axis of the sphere). A statistical analysis of waiting times between dipole reversals is also performed, obtaining a non-Poissonian distribution of waiting times, indicating long-term memory effects. We also report the presence of a 1/f frequency power spectrum in the magnetic dipole time series, which also shows a tendency to grow toward lower frequencies as the Ekman number is decreased.Fil: Fontana, Mauro.

An equivariant Reeb-Beltrami correspondence and the Kepler-Euler flow

We prove that the correspondence between Reeb and Beltrami vector fields can be made equivariant whenever additional symmetries of the underlying geometric structures are considered. As a corollary of this correspondence, we show that energy levels above the maximum of the potential energy of mechanical Hamiltonian systems can be viewed as stationary fluid flows, though the metric is not prescribed. In particular, we showcase the emblematic example of the $n$-body problem and focus on the Kepler problem. We explicitly construct a compatible Riemannian metric that makes the Kepler problem of celestial mechanics a stationary fluid flow (of Beltrami type) on a suitable manifold, the Kepler-Euler flow.Comment: 16 pages, 3 figures.

Implantação de atividades profissionais confiabilizadoras (EPAs) no ensino baseado em competências em medicina de emergência em um hospital universitário

A educação baseada em competências e o uso das atividades profissionais confiabilizadoras (EPAs) como ligação entre uma estrutura de competência e o treinamento prático médico ainda são incipientes em nosso meio. O estudo desenvolveu e implantou uma EPA relacionada ao atendimento dos pacientes clinicamente estáveis em emergência no Programa de Residência Médica do Serviço de Emergência do Hospital de Clínicas de Porto Alegre. O processo foi realizado através da constituição de um grupo de trabalho representado por médicos preceptores do Serviço de Emergência, médicos residentes e membros da equipe multiprofissional. Esse grupo elaborou a EPA utilizando a metodologia de conferência de consenso. Também foi sintetizado um guia do percurso metodológico da implantação da EPA na residência médica e descritos, através da realização de abordagem qualitativa de entrevistas em profundidade e grupos focados com profissionais de saúde e médicos residentes, os agentes facilitadores e dificultadores da implantação. Os dados receberam análise de conteúdo com pré-análise, exploração do material e tratamento dos resultados com inferência e interpretação. Esses foram divididos em 3 categorias: impactos positivos e negativos na qualidade do cuidado prestado na emergência; influência nos processos educacionais e na formação de profissionais; facilidade e dificuldades na sua implantação.Competency-based education and the use of entrustable professional activities (EPAs) as a link between a competency framework and practical medical training are still incipient in our context. The study developed and implemented an EPA related to the care of clinically stable patients in the Medical Residency Program of the Emergency Service of the Hospital de Clínicas de Porto Alegre. The process was carried out through the constitution of a working group represented by preceptors of the Emergency Service, resident physicians and members of the multidisciplinary team. This group designed the EPA using the consensus conference methodology. A guide to the methodological path of EPA implementation in medical residency was also synthesized and described, through a qualitative approach of in-depth interviews and focus groups with health professionals and resident physicians, the facilitating and hindering agents of the implementation. The data underwent content analysis with pre-analysis, material exploration and treatment of results with inference and interpretation. These were divided into 3 categories: positive and negative impacts on the quality of care provided in the emergency; influence on educational processes and training of professionals; ease and difficulties in its implementation

2N or infinitely many escape orbits

In this short note, we prove that singular Reeb vector fields associated with generic Melrose-type $b$-contact forms have either (at least) $2N$ or an infinite number of escape orbits, where $N$ denotes the number of connected components of the critical set. We obtain this result as a corollary of the same statement for the number of escape orbits of singular Beltrami fields using the singular version of Etnyre-Ghrist's contact/Beltrami correspondence.Comment: 12 pages, for Alain Chenciner on his 2N-birthda

Análisis de las herramientas de competitividad impulsadas en la economía ecuatoriana como eje de desarrollo económico durante el mandato del presidente Rafael Correa en el período 2007-2011

La competitividad ha sido analizada a lo largo de la historia contemporánea y diversos pensadores han inquietado a la sociedad sobre la importancia de contar con factores internos o externos para crear niveles de bienestar en la sociedad. Desde el siglo XVIII, el proceso sobre mejoramiento de la productividad a nivel interno ha tenido un nivel de estudio amplio para conocer las razones por las que los niveles de crecimiento son asimétricos

De l’adhésion à l’exercice d'une responsabilité syndicale, facteurs d’engagement, de renforcement et obstacles à l’agir syndical

L’étude dont nous rendons compte dans ce rapport traduit une double déci- sion : celle de la Direction Régionale du Travail de l’Emploi et de la Formation Professionnelle de Midi-Pyrénées de soutenir les organisations syndicales dans leurs fonctions d’accueil, d’accompagnement et de formation des futurs acteurs du dialogue social; et celle de l’Institut régional du travail de Midi- Pyrénées d’inaugurer une démarche de recherche sur les militants-es syndi- caux, en l’occurrence celles et ceux qui ont pris récemment une responsabi- lité syndicale. Dans cette optique, l’Irt a proposé une dynamique de travail associant au pro- tocole de la recherche et plus particulièrement dans ses moments cruciaux, des représentants des trois organisations syndicales.L’objet du questionnement initial est celui de la prise de responsabilité syndicales et de son exercice : quelles en sont ses modalités, quels sont les facteurs déterminants qui influent sur la décision de passer d’une situation d’adhérent-e ou de salarié-e sensibilisé-e au fait syndical à celle de responsable syndicale? Existe-t-il des conditions favorables ou défavorables
