Nuclear Responses to Electro-Weak Probes and In-Medium Chiral Perturbation Theory

We discuss two topics concerning the application of chiral perturbation theory to nuclear physics: (1) the latest developments in the study of possible kaon condensation in dense baryonic systems; (2) nuclear responses to electro-weak probes.Comment: 9 pages, invited talk at WEIN'95, Osaka, Japa

Model Independent Electromagnetic corrections in hadronic τ\tau decays

The long distance correction to the total decay width of the $\tau^{\pm}\to K^{0}\pi^{\pm}\nu$ decay is calculated in a model independent approach where a discrimination of photons in the Bremmstrahlung process is assumed. This correction is completely free of UV and IR singularities and moreover, it satisfies electromagnetic gauge invariance. The result of this work can be applied on the tau decays: $\tau^{\pm}\to \pi^{\pm}\pi^{0}\nu, K^{\pm}\pi^{0}\nu$

Resource Relationship Characteristics of Homeless Youth Accessing Higher Education Opportunities

This phenomenological study sought to explore how resource relationships impact college independent students during his/her homeless experience, while accessing higher education opportunities. Six students were interviewed at a Colorado university about their individual experiences. It was found that experiences pertaining to collegiate aspirations, educational barriers, accessing resource opportunities, and finding supplemental support were shared between the participants. Three major areas were identified as access areas for finding support including educational settings, community organizations, and intimate connections. These relationships assisted in providing social capital, based primarily on trust, as well as skill building and navigating the process of accessing college opportunities

El diálogo social en España: Perspectiva jurídico-profesional

Este trabajo se ha desarrollado en el marco de una red de investigadores que, perteneciendo al ámbito jurídico laboral, aunan sus backgrounds -no solo científico-teóricos sino también científico-prácticos- para fortalecer el concepto internacional de Trabajo Decente.El diálogo social se perfila, sin duda, como una herramienta clave para el mantenimiento de la paz social. Especialmente las relaciones laborales, tradicionalmente asentadas sobre la cooperación, necesitan repensar el papel que la buena fe negocial desempeña en su ordenación jurídico-normativa. En concreto la búsqueda y el análisis de la influencia de las relaciones colectivas en la integración y desarrollo del Trabajo Decente.Universidad de Málaga.

La evolución de los conceptos de espacio y tiempo

Newton desarrolló la ciencia de la mecánica bajo la hipótesis de que el tiempo y el espacio son absolutos. A principios del siglo XX Einstein desarrolló la teoría de la relatividad en la que el espacio y el tiempo ya no son absolutos, sino que están integrados en la estructura espacio-tiempo. La cosmología moderna, basada en la teoría general de la relatividad, presentó tres escenarios, dos de ellos corresponden a un universo infinito e ilimitado mientras que el tercero es un universo curvo finito pero ilimitado. La verdadera estructura del universo depende de la densidad másica de éste

Alternative calculation of the physical mass of the p-meson

We have derived an expression for the physical mass and width of the ρ-meson in vacuum from its spectral function, calculated in the vector meson dominance model when a ρ 0 meson couples to two virtual pions π +–π −. The propagator is computed after evaluating the ρ-meson self-energy. The real part of the ρ-meson self-energy is given by a divergent integral and needs to be regularized; the regularization is done by using a double subtracted dispersion relation. The result leads to a closed analytical expression which allow us to evaluate the spectral function in a closed way. The physical mass, defined as the magnitude of the four-momentum |k| for which the spectral function S(k 2 ) attains its maximum value, is obtained, and it gives a value of 770 MeV, which is in total agreement with the reported experimental value of the ρ-meson mas
