this paper is about EU “soft policies” on immigrant integration. It analyzes the “Common Basic Principles” (CBPs) and the “European Integration Fund” (EIF), two devices that have been recently established within this framework. It adopts the theoretical perspective of the “anthropology of policy” and “governmentality studies”. It shows the context of birth of the aforementioned devices, as well as their functioning and the assessment done by the actors implied in the elaboration/implementation/evaluation of the related policies. It is based both on documentary research as well as direct observation and interviews done to the actors implied. It concludes that the PBC and the EIF should be considered as a “technology of government”, that strives to align the conduct of the actors with the governmental aims, as well as it produces specific practices and knowledge. It also underlines an intrinsic feature of many policies: their “congenital failure”, since they are (often) disputed and resignified by situated actors, who are embedded in asymmetrical power relations.

La realidad del voluntariado es sumamente compleja hasta el punto de que resulta complicado definir y caracterizar el trabajo voluntario, dada la gran variedad de interpretaciones, motivaciones, variables sociodemográficas y aspectos culturales que configuran el perfil de los voluntarios. El objetivo de este trabajo es analizar la influencia conjunta de algunas variables sociodemográficas, así como de los valores culturales de índole secular o tradicional, sobre el perfil de los voluntarios en Europa. Además, se investiga qué variables orientan a los voluntarios hacia un determinado tipo de voluntariado u otro. Para ello se ha aplicado principalmente una metodología de regresión logística a partir de la información disponible en la European Value Study. Los resultados obtenidos ayudan a establecer una caracterización del voluntariado en Europa, y confirman la influencia de los valores culturales, en primer lugar, en la realización o no de trabajos de voluntariado, y en segundo lugar, en la elección que hacen estas personas del tipo de actividad con la que están comprometidos. Al analizar dos tipos de voluntariado de motivación supuestamente muy diferente, se concluye que existe un grupo de valores que influyen en ambos, aunque el sentido y la intensidad en la que lo hacen sea diferente; por otra parte, algunos valores tienen influencia o no en la realización de trabajos de voluntariado, dependiendo del tipo específico al que nos refiramos.

La globalización ha recrudecido más si cabe la competencia en los mercados y las empresas deben afianzar y mejorar su posición competitiva para asegurar la supervivencia. Para ello resulta vital, entre otras cuestiones, velar por los intereses de los inversores al tiempo que cuidan de sus clientes. Las cooperativas sufren una coyuntura semejante respecto a sus socios y el mercado, es decir respecto a sus clientes internos (socios) y externos (mercado). El enfoque de las actividades y la estrategia de la cooperativa frente a esta dualidad determina su grado de orientación al mercado.Los estudios relacionados con la orientación al mercado en cooperativas son escasos en comparación con otras formas empresariales y han estado normalmente centrados en la figura de las cooperativas de segundo grado y circunscritos a sectores muy específicos.El sector citrícola español es uno de los más dinámicos y desarrollados del panorama productivo agrario. Su extensa experiencia comercial tanto a nivel doméstico como internacional confiere un carácter diferenciador a las entidades que operan en este subsector. Este trabajo analiza la posición de las cooperativas citrícolas españolas en relación a la orientación al mercado así como los factores de gestión y estrategia que están relacionadoscon ella. Para ello se utiliza una escala MARKOR, validada en estudios anteriores, sobre una muestra de 45 cooperativas.Se establece además una tipología de cooperativas citrícolas en base a los factores de competitividad que permiten ahondar en el conocimiento que existe sobre esta cuestión en entidades de economía social. Los resultados ponen de manifiesto un elevado grado de relación entre la innovación, el perfil del empresario y el conocimiento del entorno en relación con el grado de orientación al mercado.

Cooperatives, as a kind of firms, are considered by many scholars as an remarkable alternative for overcoming the economic crisis started in 2008. Besides, there are other scholars which pointed out the important role that these firms play in the regional economic development. Nevertheless, when one examines the economic literature on cooperatives, it is detected that this kind of firms is mainly studied starting from the point of view of their own characteristics and particularities of participation and solidarity. In this sense, following a different analysis framework, this article proposes a theoretical model in order to explain the behavior of cooperatives based on the entrepreneurship theory with the aim of increasing the knowledge about this kind of firms and, more specifically, their contribution to regional economic development.

This article examines the socio-economic evolution of the social economy sector in the Basque Country during the 2008-2014 period of economic crisis. Data have been obtained within a framework of collaboration between university, Basque Government and private sector of the social economy. The results suggest that such entities have evolved better, both in terms of number of enterprises and employment, than the general economy of the Basque Country, while the context of public policies aimed at social economy has worsened over the years. However, in economic terms (measured through the Gross Value Added generated), they have not been able to cope with the crisis in equal conditions to the general economy. The main contribution of this research lies in that, unlike similar studies, it discusses the evolution of the whole sector of the social economy, taking as reference a broad period of the current economic crisis.

In this paper the claim for the market for a new business management to ensure the presence of women in decision -making to respond to new social needs addressed. Thus, this paper analyzes the influence of gender diversity of the directors on the profitability and the level of debt for a sample of 5,199 Spanish cooperatives. Unlike capitalist societies, these organizations have a number of peculiarities in their government, and that the partners are themselves major time, agents and customers. The study focuses on the Spanish context, where there is an open debate on the importance of women's business management, as in other countries, driven by the proliferation of legislation on gender equality, being, in addition, Spain, the pioneer in having specific legislation on Social Economy. The results show that cooperatives with greater female representation in theirs Boards have higher profitability. On the other hand, those Boards with a higher percentage of women show a lower level of indebtedness.

Access to higher education has increased among students with disabilities, and universities are adopting different alternatives which must be assessed. The purpose of this study was to identify the situation of a sample of students with disabilities (n=91) who attend a university in Spain, through the design and validation of the “CUNIDIS-d” scale, with satisfactory psychometric properties. The results show the importance of making reasoned curriculum adaptations, adapting teacher training, improving accessibility and involving all the university community. Different proposals were provided which support the social dimension of the EHEA.

Las organizaciones empresariales han cambiado desde inicios del siglo XX hasta la actualidad. Este cambio es continuo y los nuevos escenarios invitan a una participación más activa de la pedagogía en el entorno empresarial. Ahora no es suficiente con competir para obtener un mayor beneficio, también es necesario innovar bajo el paraguas de la sostenibilidad y tener presente la realidad social en la que se encuentra la empresa. Las personas ocupan un papel aun más protagonista en las organizaciones empresariales de sociedades avanzadas. La pedagogía no debe ni puede permanecer al margen. La formación, la capacitación, la cualificación, la capacidad de innovación y la vinculación de la persona con la organización son las claves para el desarrollo, crecimiento y supervivencia de las organizaciones empresariales. La formación debe colaborar desde una perspectiva pedagógica. No debe limitar su actuación a ámbitos externos de la empresa (antes de la incorporación de la persona, o cuando la persona no está en el mercado laboral). Debe actuar desde dentro de las organizaciones empresariales.

The transformation of the Information and Communication Technologies (ICT) into knowledge and learning technologies is increasingly becoming a matter of concern. Teaching settings associated with the use of blogs in Higher Education are presented in this paper, proceeding from an innovative learning experience of projects carried out by a group of professors between 2009 and 2013. Both, teachers and students who took part in the subjects that implemented the blog, considered it as helpful resource to create a virtual and learning-teaching environment due to the multiple potentialities it offers. Among some of these potentialities, some stand out: it makes easier the access to knowledge, promotes a more active and reflective learning, expands the social experience of learning, provides evidence about the students’ progress which helps to reorient the teaching-learning process, and encourages the critical judgment. Nevertheless, several problems related with the students’ participation and the teacher’s blog management have been identified.

Los beneficios que aporta la musicoterapia en alumnos con Trastorno del Espectro Autista, han sido demostrados profusamente por los distintos autores, si bien carecemos de literatura suficiente sobre su utilización en las Aulas Abiertas Especializadas en colegios ordinarios (Aulas TEA). En este sentido, el objetivo del trabajo, ha consistido en analizar qué mejoras aporta la musicoterapia al desarrollo de la comunicación en los alumnos con Trastorno del Espectro Autista dentro de las Aulas Abiertas de los CEIPs de Castilla-La Mancha y la Comunidad Autónoma de Madrid. Para ello, se ha realizado una amplia revisión documental de fuentes de referencia y se ha entrevistado a los docentes responsables de las Aulas Abiertas Especializadas que utilizan actividades de musicoterapia como recurso en el aula. Se concluye el artículo manifestando, en primer lugar, la escasa integración de la musicoterapia en las aulas TEA (menos del 20% de los centros). En aquellas aulas que sí se programa con actividades de musicoterapia, los beneficios que ésta aporta se ven reflejados en un incremento claro de la intención comunicativa en los alumnos. Además, a la hora de planificar las actividades se tiene muy en cuenta conocer las preferencias y la historia musical del niño. No obstante, existen factores que impiden el aprovechamiento total de las posibilidades terapéuticas de la musicoterapia debido, especialmente a: a) una escasa formación del profesorado y b) un espacio inadecuado para poner en práctica una sesión de musicoterapia.

In this article, we address the importance and relevance that social networks exhibit in their use as an educational resource.  This relevance relies in the possibility of implementing new learning resources or increasing the level of the participant's connectivity, as well as developing learning communities.  Also, the risk entailed from their use is discussed, especially for the students that have a low technological education or those having excessive confidence on the media.  It is important to highlight that the educational use of social networks is not a simple extension or translation of the student's habitual, recreational use, but that it implies an important change in the roles given to teachers as well as learners; from accommodative learning environments that only encourage memorization to other environments that demand an active, reflective, collaborative and proactive attitude, that require the development/acquisition of technological as well as social abilities, aptitudes and values.  It is also important to highlight that a correct implementation and adequate use will not only foment formal learning, but also informal and non-formal learning.

Voltammetric studies of PCl3 and POCl3 have not been reported in the literature to date, probably due to the instability of these molecules in conventional aprotic solvents giving unstable and irreproducible results. From a previous study [Amigues et al. Chem. Commun. 2005, 1-4], it was found that ionic liquids have the ability to offer a uniquely stable solution phase environment for the study of these phosphorus compounds. Consequently, the electrochemistry of PCl3 and POCl3 has been studied by cyclic voltammetry on a gold microelectrode in the ionic liquid [C(4)mpyrr][N(Tf)(2)] (1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) imide). For both compounds, reduction and oxidation waves were observed and a tentative assignment of the waves is given. For PCl3, the reduction was thought to proceed via the following mechanism: PCl3 + e(-) h reversible arrow PCl3-, PCl3- reversible arrow Cl- + (PCl2)-Cl-center dot, (and) Cl- + PCl3 h PCl4-. For POCl3, the suggested reduction mechanism was analogous to that of PCl3: POCl3 + e(-) reversible arrow POCl3-, POCl3- reversible arrow Cl- + (POCl2)-O-center dot, and Cl- + POCl3 h POCl4-. In both cases (PCl2)-Cl-center dot and (POCl2)-O-center dot are likely to engage in further reactions. Potential step microdisk chronoamperometry was carried out on the reductive waves of PCl3 and POCl3 to measure diffusion coefficients and number of electrons transferred. It was found that the diffusion of PCl3 was unusually slow (3.1 x 10(-12) m(2) s(-1)): approximately 1 order of magnitude less than that for POCl3 (2.2 x 10(-11) m(2) s(-1)). For both PCl3 and POCl3, a

Lecithin:cholesterol acyltransferase (LCAT) is a key enzyme involved in lipoprotein metabolism. It mediates the transesterification of free cholesterol to cholesteryl ester in an apoprotein A-I-dependent process. We have isolated purified LCAT from human plasma using anion-exchange chromatography and characterized the extracted LCAT in terms of its molecular weight, molar absorption coefficient, and enzymatic activity. The participation of LCAT in the oxidation of very low density lipoproteins (VLDL) and low-density lipoproteins (LDL) was examined by supplementing lipoproteins with exogenous LCAT over a range of protein concentrations. LCAT-depleted lipoproteins were also prepared and their oxidation kinetics examined. Our results provide evidence for a dual role for LCAT in lipoprotein oxidation, whereby it acts in a dose-responsive manner as a potent pro-oxidant during VLDL oxidation, but as an antioxidant during LDL oxidation. We believe this novel pro-oxidant effect may be attributable to the LCAT-mediated formation of oxidized cholesteryl ester in VLDL, whereas the antioxidant effect is similar to that of chain-breaking antioxidants. Thus, we have demonstrated that the high-density lipoprotein-associated enzyme LCAT may have a significant role to play in lipoprotein modification and hence atherogenesis. (C) 2007 Elsevier Inc.
