Discrimination Because of Family Reconciliation Reasons

[Resumen] En este trabajo de fin de grado, discriminación por circunstancias de conciliación familiar, se intenta explicar con claridad la discriminación laboral de mujeres en comparativa con los hombres, así como, los tipos de discriminación y consecuencias jurídicas que ello conlleva. También por otra parte, se hace necesario, definir los beneficios y desventajas de dicha conciliación, y mostrar las diferencias jurídicas en la ley actual comparándolas con la anterior de la reforma laboral. Por último intentar comprender la importancia de la igualdad en las organizaciones y la integración de políticas de conciliación para el beneficio de mujeres y hombres en dicha conciliación con vida familiar y trabajo.[Abstract] This proyect, Discrimination Because of Family Reconciliation Reasons, will explain and clarify the labor discrimination of women compared to men, and also, the different types of discrimination and legal consequences involved. Moreover, we need to define the pros and cons of this conciliation, and show the legal differences between the current law and previous labor legislation. Finally, we will try to understand the importance of the gender equality in the organizations and the implementation of conciliation policies, looking for the benefit of women and men in the already stated conciliation of family and professional life.Traballo fin de grao (UDC.FCT).

Sustainability of public pension system

[Resumen] En este trabajo de fin de máster, sostenibilidad del sistema público de pensiones, se intenta explicar con claridad el problema de la sostenibilidad del modelo que hasta ahora conocemos de las pensiones públicas españolas, explicando las contingencias cubiertas y la acción protectora de la seguridad social, entendiendo los factores clave y las amenazas para ese sistema de pensiones, así también las posibles reformas que se necesitarían para hacerlo sostenible y una proyección a largo plazo. Por último incluir las soluciones que se podrían llevar a cabo para no perder lo que hasta ahora es la realidad en España, o intentar poco a poco mejorar el sistema de pensiones público con propuestas para esa sostenibilidad y una comparativa con los sistemas de pensiones privadas.[Abstract] In this Thesis, sustainability of the public pension system, attempts to explain clearly the problem of sustainability model that we have knowledge of the Spanish public pensions, explaining the contingencies covered and the protective action of social security, understanding the key factors and threats to the pension system, so possible reforms that would be needed to make it sustainable and long-term projection. Finally include solutions that could be carried out to keep what so far is the reality in Spain, or try to gradually improve the public pension system with proposals for such sustainability and a comparison with private pension systems.Traballo fin de mestrado (UDC.FCT).

Price dispersion in Uruguay

Retail prices for a product vary across time and places. The sources that drive price disp ersion can be grouped into three categories: (i) price diffrences across markets, (ii) price diferences across stores in a market, and (iii) within-store price variation over time. I find there is price dispersion in the retail market in Uruguay. The decomposition shows that 39.16 percent is across-markets, 36.90 percent corresponds to across-store, and 23.94 percent over time. These results highlight the relevance of intertemporal pricing strategies of stores, and how they set prices at the local market to understand price dispersion. Nevertheless, in recent years across-market price dispersion has been increasing, which can imply a structural change of price dispersion sources. The price dispersion phenomenon and its decomposition are heterogeneous. Across products, stores, and over time I find differences in price dispersion as well as differences in the sources behind it

Interaction of Hawking radiation with static sources in deSitter and Schwarzschild-deSitter spacetimes

We study and look for similarities between the response rates $R^{\rm dS}(a_0, \Lambda)$ and $R^{\rm SdS}(a_0, \Lambda, M)$ of a static scalar source with constant proper acceleration $a_0$ interacting with a massless, conformally coupled Klein-Gordon field in (i) deSitter spacetime, in the Euclidean vacuum, which describes a thermal flux of radiation emanating from the deSitter cosmological horizon, and in (ii) Schwarzschild-deSitter spacetime, in the Gibbons-Hawking vacuum, which describes thermal fluxes of radiation emanating from both the hole and the cosmological horizons, respectively, where $\Lambda$ is the cosmological constant and $M$ is the black hole mass. After performing the field quantization in each of the above spacetimes, we obtain the response rates at the tree level in terms of an infinite sum of zero-energy field modes possessing all possible angular momentum quantum numbers. In the case of deSitter spacetime, this formula is worked out and a closed, analytical form is obtained. In the case of Schwarzschild-deSitter spacetime such a closed formula could not be obtained, and a numerical analysis is performed. We conclude, in particular, that $R^{\rm dS}(a_0, \Lambda)$ and $R^{\rm SdS}(a_0, \Lambda, M)$ do not coincide in general, but tend to each other when $\Lambda \to 0$ or $a_0 \to \infty$. Our results are also contrasted and shown to agree (in the proper limits) with related ones in the literature.Comment: ReVTeX4 file, 9 pages, 5 figure

Do static sources respond to massive scalar particles from the Hawking radiation as uniformly accelerated ones do in the inertial vacuum?

We revisit the recently found equivalence for the response of a static scalar source interacting with a {\em massless} Klein-Gordon field when the source is (i) static in Schwarzschild spacetime, in the Unruh vacuum associated with the Hawking radiation and (ii) uniformly accelerated in Minkowski spacetime, in the inertial vacuum, provided that the source's proper acceleration is the same in both cases. It is shown that this equivalence is broken when the massless Klein-Gordon field is replaced by a {\em massive} one.Comment: 4 pages, 2 figure
