Indoor radon related with the geology in romanian urban agglomerations (cluj-napoca)

Radon is a natural radioactive gas that occurs due to the radioactive decay of radium (226Ra) present in rocks which, in turn, cames from the radioactive decay of uranium (238U), a primordial natural element. Along with factors such as porosity, permeability and humidity of the rocks and soils, pressure and temperature, geology setting plays one of the most important roles in the release of radon into the environment. Depending on the mineralogical compositions and characteristics of the bedrock from a certain area, a higher or lower concentration of radioactive minerals can be found in the rocks, which will directly influence the level of radon in the atmosphere, implicitly the concentration of radon measured in houses. In this study, a six months concentration of radon (222Rn) was assessed in 256houses from Cluj-Napoca area using CR-39 nuclear track detectors. Correlations between the indoor radon levels and the geological setting was further analyzed. The aim is to better understand the influence of geology on the concentration of radon levels in homes, in order to further identify other risk areas in terms of exposure to radon. Further investigation is needed on other factors influencing the accumulation of radon in high concentrations indoor, such as ventilation, occupation patterns or constructive and architectural features for typical houses. Therefore, the results of this work are considered to be important for indoor radon management in Romania

Reputation of the large clothing retailers in Spain

[ESP]El objetivo principal de este Trabajo Fin de Grado es analizar desde el punto de vista de los clientes la reputación de las grandes distribuidoras de moda en España. En el trabajo también se estudian otros conceptos relacionados con la reputación de las empresas como son la satisfacción, la lealtad y el boca a boca de los clientes para conocer su valoración en el sector. Para ello, se ha elaborado una encuesta online mediante la cual se han recogido las opiniones de 69 clientes de las grandes distribuido ras de moda. Como conclusión destacar que percepción de la reputación por los clientes del sector analizado es media-baja (media de 3.23 sobre 5), siendo las dimensiones utilizadas para determinarla (de mayor a menor valoración): empresa fiable y financieramente fuerte, producto y calidad del servicio, orientación al cliente, buen empleador, y responsabilidad social y medioambiental. En cuanto a la satisfacción, la lealtad y el boca a boca se obtienen igualmente valoraciones bajas. Por ello, se hacen una serie de recomendaciones para mejorar estos resultados organizativos que influyen en los resultados económicos y financieros de las empresas [ENG] he main objective of this Final Degree Project is to analyze corporate reputation of large fashion and clothing retailers in Spain from their customers’ perspective.

How do employees cope with mandatory working from home during COVID-19?

How do employees who are coerced to work from home during COVID-19 cope with this unprecedented situation? Drawing upon the job-demands-resources (JD-R) model and upon the literature on coping, we analyse empirical qualitative material which stems from two-stage interviews with and online diaries prepared by 15 white-collar employees in Romania. We identify four initial coping types in relation to mandatory working from home: 'explorers', 'statics', 'chaotics' and 'irremediables'. In the follow-up stage of the field work, the 'chaotic' type of coping disappears. These findings in relation to the unique pandemic situation represent a significant contribution to the literature on working from home as well as on coping with stress
