Assessment and control of human resource strategies in the tourism sector. Empirical evidence at Granada and Málaga province.

En un contexto económico de derrumbe de la economía real, el turismo ha adquirido un gran protagonismo como primer generador de empleo en nuestro país. En este contexto, la estrategia de recursos humanos, uno de los factores clave de éxito para conseguir una ventaja competitiva, debe ser un estímulo para que el capital humano desarrolle su carrera profesional en este sector, lo que redundará en la mejora de las expectativas de rendimientos empresariales. Sin embargo, hay que contemplar el efecto negativo producido por las diferencias existentes entre las estrategias empresariales y su implantación, en particular, en el ámbito de los recursos humanos. El objetivo de este trabajo es obtener evidencia empírica sobre la estructura y situación de los recursos humanos en el sector turístico andaluz desde la perspectiva de las actuaciones impulsadas por las empresas del sector (con especial referencia a Málaga y Granada). La metodología empleada para su análisis ha sido el método estadístico, en la versión basada en la moda, tras categorizar los establecimientos hoteleros (de Málaga y Granada) utilizando el análisis discriminante de la información económica agregada, más relevante, de cada empresa. Para la aplicación del método estadístico se ha utilizado la información proveniente de una encuesta, realizada a establecimientos hoteleros, y un análisis Delphi, a expertos y líderes sociales del sector. La Conclusión más relevante, en términos generales, se refiere al desajuste existente entre la valoración de la importancia que se asigna a la Estrategia de Recursos Humanos y al desarrollo que, en la práctica, se realiza de la misma. Todo lo cual refleja una política que no favorece la retención de talentos.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Stress-strain response and microstructural evolution of a FeMnCAl TWIP steel during tension-compression tests

© 2016. The stress-strain response of a Fe-17.5Mn-0.7C-2Al TWIP steel during cyclic loading has been investigated by means of tension-compression tests within the strain limits of ±2%, ±5% and ±10%. In addition, the microstructural evolution during the ±5% cyclic test has also been studied. The difference between the forward and reverse stress for each pre-strain has been analyzed at 0.2% offset strain and at the strains in which forward and reverse curves were parallel in order to study the Bauschinger effect (BE) and permanent softening, respectively. The evolution of the BE with pre-strain for this steel is similar to other FeMnC TWIP steels, that is, increasing values of BE are obtained as the pre-strain increases. However, its absolute values are half those reported in the literature on other FeMnC steels. This diminution of the BE is related to the lower activity of mechanical twinning in FeMnCAl TWIP steels at the pre-strains herein investigated, which promotes less polarized stresses in the matrix due to the lower dislocation storage capacity.Regarding permanent softening, the evolution is similar to that of the BE and the same analysis can be applied. During reverse compression, a slight increase of twin thickness and twin spacing with respect to the first tensile stage took place. This fact might be linked to the lower flow stress observed in the permanent softening period during reverse straining.Peer ReviewedPostprint (author's final draft

Safeguarding Health at the Workplace: A Study of Work Engagement, Authenticity and Subjective Wellbeing among Religious Workers

: Research in work and organizational psychology has paid little attention to religious workers, something certainly surprising as faith-based organizations play a key role in the welfare state of many countries. This research shows that religious workers in a Catholic order present a high degree of subjective wellbeing, both in terms of flourishing and satisfaction with life in general, and a positive balance of positive and negative feelings. More specifically, this study examines the relationship between authenticity and wellbeing amongst religious workers. Survey responses from 142 religious workers in Spain were analyzed using partial least squares path modelling. The results reveal that subjective wellbeing at work is positively related to authenticity. In addition, this relationship is mediated by their level of work engagement

Surface growth for molten silicon infiltration into carbon millimeter-sized channels: Lattice-Boltzmann simulations, experiments and models

The process of liquid silicon infiltration is investigated for channels with radii from $0.25$ to $0.75$ [mm] drilled in compact carbon preforms. The advantage of this setup is that the study of the phenomenon results to be simplified. For comparison purposes, attempts are made in order to work out a framework for evaluating the accuracy of simulations. The approach relies on dimensionless numbers involving the properties of the surface reaction. It turns out that complex hydrodynamic behavior derived from second Newton law can be made consistent with Lattice-Boltzmann simulations. The experiments give clear evidence that the growth of silicon carbide proceeds in two different stages and basic mechanisms are highlighted. Lattice-Boltzmann simulations prove to be an effective tool for the description of the growing phase. Namely, essential experimental constraints can be implemented. As a result, the existing models are useful to gain more insight on the process of reactive infiltration into porous media in the first stage of penetration, i.e. up to pore closure because of surface growth. A way allowing to implement the resistance from chemical reaction in Darcy law is also proposed

The Subjective Well-Being Challenge in the Accounting Profession: The Role of Job Resources

The main activity of the accountant is the preparation and audit of the financial information of a company. The subjective well-being of the accountant is important to ensure a balanced professional judgment and to offer a positive image of the profession in the face of the incorporation and retention of talent. However, accountants are subjected to intense pressures that affect their well-being in the performance of their tasks. In this paper, the job demands–resources theoretical framework is adopted to analyze the relationships between job demands, job resources, and the subjective well-being of a large sample of 739 accounting experts at the European level. Applying a structural equations model, the results confirm, on the one hand, the direct effects provided in the theoretical framework and, on the other, a new mediating role of job demands–subjective well-being relationship resources
