State of the issue and new challenges of Social Work: reflections of recently graduated professionals from Peru and Spain

Currently the primacy of the market economy in most of the nations is constituted as a global phenomenon, which has direct consequences on the structure of the different states socio-political systems. In this framework, the way in which the relations between the market and each nation-state are materialized, including their intervention strategies, generate differential contexts with relevant implications in various areas, including education. These relationships deeply affect the social protection systems and especially the Public System of Social Services, traditionally associated with the most vulnerable and less economically solvent population. The discipline of Social Work is no stranger to this situation, living in recent years convulsive moments both in terms of the construction of own knowledge and in the practice of the profession. Given this situation, it is intended to obtain the discourse that social workers have on aspects as important as the relevance of the training model, the significance given to research, the social imaginary around the discipline or the adequacy of the available resources for the exercise of the profession.Universidad de Málaga.

Hints for the existence of hexaquark states in the baryon-antibaryon sector

The discovery of some baryon-antibaryon resonances has led us to consider 3q~3\bar{q} systems as possible candidates. We predict their spectrum in the framework of a constituent model, where the chromo-magnetic interaction plays the main role. The relevant parameters are fixed by the present knowledge on tetraquarks. The emerging scenario complies well with experiment. Besides the description of the baryon-antibaryon resonances, we find evidence for new tetraquark states, namely the a0(Y) in the hidden strangeness sector and, in the cs\bar{c}\bar{s} sector, the Y(4140) and the X(4350). A detailed account of the spectra and the decay channels is provided for future comparisons with data.Comment: 17 page

Core Losses and Torque Ripple in IPM Machines: Dedicated Modeling and Design Trade Off

The proper combination of stator and rotor slot numbers is pursued in the design of interior permanent-magnet (IPM) motors with wide constant-power speed range. At high speed, in the flux-weakening region, the arising of stator and rotor iron losses due to magnetomotive-force (MMF) spatial harmonics limits the IPM motor performance. Torque ripple is another problem for this kind of machines, both at low and high speed. The numbers of stator slots and rotor equivalent slots have a major impact on both the loss and ripple aspects. A simplified model is proposed here in order to evaluate both problems with a general approach and point out the possible design tradeoff. With respect to previous models in the literature, both stator and rotor losses are included, and a more comprehensive approach is followed in the description of the rotor MMF harmonics. The model's effectiveness is tested through finite element analysis simulations and some experimental results. The proposed approach is useful for the selection of the IPM machine structure according to the specific requirements of the applicatio
