Del desempleo como riesgo al desempleo como trampa: ¿Qué distribución de las responsabilidades plantea el paradigma de la activación propuesto por las instituciones europeas?
The purpose of this contribution is to discuss the social and ethical principles underlying the new model of social intervention proposed by these bodies. To promote and place in circulation concepts that will fuel public debate is an approach to the achievement of supranational regulation increasingly favoured by the European institutions. Here, in relation to the specific case of activation, we will discuss both the differing ways in which the model is utilised and the effects entailed by its implementation, as well as how it affects the adjudication of responsibilities between the welfare state, workers and employers. A diagnosis of the problem will be proposed and explored, together with possible and legitimate alternatives for its resolution. The activation paradigm posits a transformation of the social and ethical underpinnings of the social contract, requiring us to take up a moral stance in relation to unemployment and social exclusion. It accordingly fosters a change in ideological and terminological presuppositions —in what is taken for granted— as a means of depoliticising the handling of the social conflicts likely to accompany current developments in changing production models, in order to prevent the socio-political nature of social exclusion from emerging. The point is to avoid all consideration of this issue, thereby forestalling any questions of power or oppression that might be raised.El objetivo de esta contribución es analizar los principios sociales y morales del modelo de intervención social propuesto por las instituciones europeas. La extensión y difusión de conceptos articuladores de debates políticos es el eje nuclear de esta regulación supranacional. Se planteará el caso específico de la activación, en el cual, se discutirá qué tipo de diagnóstico del problema plantea, las alternativas posibles y legítimas para su resolución, así como su propuesta de articulación de responsabilidades entre el Estado social, el trabajador y los empleadores. Este paradigma de la activación plantea un proceso de transformación de los ejes sociales y morales en torno a los cuales se articula la cuestión social, dirigiéndonos hacia un enfoque moral frente al desempleo y a la exclusión social. Se está estimulando un cambio ideológico y terminológico de las cuestiones dadas por supuesto, cuya función es despolitizar la gestión del conflicto social que puede acompañar al desarrollo de las actuales condiciones del modelo productivo, incapacitando la emergencia del carácter sociopolítico de la exclusión social
New perspectives on employability and labour market policy: reflecting on key issues
This editorial introduces a theme issue on ``New Perspectives on Employability and Labour Market Policy''. The papers that follow were developed by participants in a cross-national research network established with the support of the Regional Studies Association, which aimed to share knowledge on both the individual and spatial dimensions of employability and labour market exclusion, and related policy responses. The papers were selected to take in research on barriers to work and job-search strategies among different groups, the role of employers in providing opportunities for job seekers, how the geography of labour markets shapes the experience of unemployment, and local and regional governance arrangements that provide the context for policy responses
Propiedades psicométricas de la versión española del "Cuestionario de responsabilidad personal y social" en contextos de educación física
El objetivo del presente trabajo ha consistido en analizar las propiedades psicométricas de la versión española del Cuestionario de Responsabilidad Personal y Social (Personal and Social Responsibility Questionnaire-PSRQ), que evalúa la percepción de responsabilidad personal y social de los alumnos en educación física. La muestra fue seleccionada por conveniencia, y la formaron 395 alumnos de 9 a 15 años, pertenecientes a 10 colegios públicos y concertados de la Comunidad Valenciana. Los resultados del análisis factorial confirmatorio han corroborado la estructura bifactorial propuesta por sus autores, y los coeficientes de consistencia interna han resultado satisfactorios. Por otro lado, las correlaciones de los factores de responsabilidad con la motivación intrínseca han sido positivas y estadísticamente significativas, apoyando su validez criterialThe purpose of this study was to analyse the psychometric properties of the Spanish version of the Personal and Social Responsibility Questionnaire (PSRQ), which assesses students' perception of personal and social responsibility in physical education. The sample was selected on the basis of convenience and consisted in 395 students, ages 9 to 15, from 10 primary and secondary schools in the Community of Valencia. The results of the confirmatory factor analysis supported the bifactorial structure proposed by its authors and its internal consistency coefficients were satisfactory. The correlations between the responsibility factors and intrinsic motivation were positive and statistically significant, which supported the validity of the criteri
Observación de las estrategias que emplean los profesores de educación física para enseñar responsabilidad personal y social
The purpose of this study was two-fold: (1) to analyse the psychometric properties of the Spanish version of the first part of the "Tool for Assessing Responsibility-based Education (TARE)" that we have called instrumento de observación de las estrategias de los profesores para enseñar responsabilidad; (2) to analyse the strategies used by 4 physical education teachers in their classes. The results revealed, on the one hand, that the validity and reliability of the Spanish version of the TARE were satisfactory. On the other hand, the four teachers showed strategies that fostered respect and gave all the students opportunities for success. Additionally, differences in teachers' strategies for giving students choices and voices were found. Nevertheless, teachers did not use many strategies for fostering students' autonomy and leadership. Thus, all teachers showed low use of strategies for fostering students' role in assessing their own learning and transferring to other contexts
Inserción laboral como transición psicosocial
Esta investigación ha consistido en una reflexión acerca de los procesos de inserción y socialización laboral del joven, entendiendo dicha inserción como un proceso de transición psicosocial al mundo adulto. El análisis de las formas bajo las cuales algunos jóvenes están llevando a cabo su inserción en el mundo adulto en el momento actual ha puesto de manifiesto las tensiones y contradicciones ante las que muchos de ellos están sometidos entre, por un lado, una demanda normativa implícita que hace del joven un estado deficitario (en términos de reciprocidad, agencia y racionalidad) y por otro, las condiciones de precariedad del mercado de trabajo que les instala en esta condición transitoria juvenil como un estado permanente. Se analizan las consecuencias de esta situación en la diversificación de las trayectorias de inserción, por un lado, y en la definición de plurales estadios adultos de llegada, por otro. Se ha observado que si la inserción al trabajo, y con ella, al mundo adulto, de ciertos jóvenes implicaba una afirmación de valores propios de la modernidad (reciprocidad, progreso y agencia), la inserción de otros instalaba a estos en la inestabilidad y en la polisemia como principios de vida. Esta polisemia explicaba su visión del mundo pluricentrada que les permitía desplazarse entre distintos planos semánticos, muchas veces antitéticos entre si, a través de los cuales se dotaba de sentido a la realidad social y laboral. Esta situación tenia el efecto paradójico de preparar y de dotar de estrategias mas adecuadas a estos jóvenes para el enfrentamiento ante la polivalencia y el cambio constante que caracterizan la situación del capitalismo avanzado en el que esta instalada la sociedad española actua
Different Toxicity Mechanisms for Citrinin and Ochratoxin A Revealed by Transcriptomic Analysis in Yeast
[EN] Citrinin (CIT) and ochratoxin A (OTA) are important mycotoxins, which frequently co-contaminate foodstuff. In order to assess the toxicologic threat posed by the two mycotoxins separately or in combination, their biological effects were studied here using genomic transcription profiling and specific live cell gene expression reporters in yeast cells. Both CIT and OTA cause highly transient transcriptional activation of different stress genes, which is greatly enhanced by the disruption of the multidrug exporter Pdr5. Therefore, we performed genome-wide transcription profiling experiments with the pdr5 mutant in response to acute CIT, OTA, or combined CIT/OTA exposure. We found that CIT and OTA activate divergent and largely nonoverlapping gene sets in yeast. CIT mainly caused the rapid induction of antioxidant and drug extrusion-related gene functions, while OTA mainly deregulated developmental genes related with yeast sporulation and sexual reproduction, having only a minor effect on the antioxidant response. The simultaneous exposure to CIT and OTA gave rise to a genomic response, which combined the specific features of the separated mycotoxin treatments. The application of stress-specific mutants and reporter gene fusions further confirmed that both mycotoxins have divergent biological effects in cells. Our results indicate that CIT exposure causes a strong oxidative stress, which triggers a massive transcriptional antioxidant and drug extrusion response, while OTA mainly deregulates developmental genes and only marginally induces the antioxidant defense.We thank Lorena Latorre and Javier Forment for their help with the microarray experiments and data analysis.

Se trata de una investigación cualitativa a través de un doble estudio de casos. Las participantes fueron dos profesoras generalistas de Educación Primaria. La obtención de los datos se realizó a través de diarios personales y entrevistas. Para las participantes las fortalezas de la formación fueron: el intercambio de experiencias entre los participantes, el efecto motivador que tuvo que el facilitador del curso fuera un experto profesor de una universidad extranjera y la presentación de un nuevo enfoque metodológico más flexible en la aplicación del PRPS. Los puntos débiles de la formación fueron: la corta duración de la formación y una oferta insuficiente de actividades prácticas para el desarrollo de la responsabilidad en los niños. Las propuestas de mejora hechas por los participantes contemplaron el incremento de actividades prácticas específicas para el desarrollo del liderazgo y la transferencia, así como la utilización de una metodología basada en el active learning (Bonwell y Eison, 1991).This paper examines the assessment that the teachers participating in a training course did to improve the implementation of Personal and Social Responsibility Program (PSRP) (Escartí, Pascual and Gutierrez, 2005) at school. This is a qualitative research through a double case study. Participants were two primary school teachers. Data were collected from teacher’s diaries and interviews. Findings: For the participants the strengths of the teacher training were: the exchange of experiences between participants, the motivating effect of the fact that the training facilitator was an expert teacher in a foreign university, and the presentation of a new more flexible methodological approach to implement PSRP. The teacher training weaknesses were: the short duration of training and the insufficient supply of practical activities to develop responsibility in children. In order to improve teacher training in PRPS the participants proposed specific practical activities to develop leadership and transference, and the use of a methodology based on active learning (Bonwell and Eison, 1991)
