El impacto sobre los trabajadores de una gestión de recursos humanos socialmente responsable. Un análisis para Catalunya

Socially responsible human resource management constitutes the conceptual-theory framework of the thesis. The results obtained from the empirical part show the existence of three clusters inasmuch as the application of socially responsible practices for promoting job quality in the case of Catalonia: the group of workers in “organizations with low-level of social responsibility”; those who work in a environment of “work practices for implication” and the group of workers in a environment oriented to “health and safety at work”. Among the determining factors in applying these practices we can find characteristics of the firms where the employees work as well as personal characteristics and those of the job. The research also shows that, in general, applying socially responsible management in human resources does have positive effects on the worker and therefore creates greater trust in management, increased job satisfaction, less stress at work and a lower intention to quit a job.

WMR navigation using local potential field corridors and narrow local occupancy grid perception

Path planning and control strategies applied to autonomous mobile robots should fulfil safety rules as well as achieve final goals. Trajectory planning applications should be fast and flexible to allow real time implementations as well as environment interactions. The methodology presented uses the on robot information as the meaningful data necessary to plan a narrow passage by using a corridor based on attraction potential fields that approaches the mobile robot to the final desired configuration. It employs local and dense occupancy grid perception to avoid collisions. The key goals of this research project are computational simplicity as well as the possibility of integrating this method with other methods reported by the research community. Another important aspect of this work consist in testing the proposed method by using a mobile robot with a perception system composed of a monocular camera and odometers placed on the two wheels of the differential driven motion system. Hence, visual data are used as a local horizon of perception in which trajectories without collisions are computed by satisfying final goal approaches and safety criteria
