Novedades sobre derechos de información y facilidades para los representantes de los trabajadores en supuestos de subcontratación

Los fenómenos de descentralización productiva y de fragmentación de las estructuras empresariales generan problemas para articular la protección de los trabajadores a través de representaciones colectivas a nivel de empresa. El legislador ha tomado conciencia de esas dificultades y ha introducido algunos mecanismos correctores. Este estudio analiza con detalle el libro registro, como obligación documental en los supuestos de subcontratación y que sirve de apoyo a los derechos de información y las facultades de vigilancia de los representantes de los trabajadores en la empresa y las novedades en materia de coordinación de actividades entre representantes de los trabajadores de diferentes empresas en los supuestos de desarrollo de actividades en un mismo espacio físico.

El modelo sueco de cuidados a la infancia y sus consecuencias sobre las mujeres

La política familiar en Suecia constituye un pilar básico de su Estado de Bienestar, teniendo entre sus objetivos el reparto equitativo del trabajo de cuidados infantiles entre las madres y los padres. Este artículo analiza el impacto y las consecuencias, en términos de igualdad, de las medidas familiares: si todos tienen las mismas responsabilidades familiares y laborales porqué las mujeres se han comprometido en un alto grado con el mercado de trabajo y los hombres no han cumplido con su parte de los cuidados familiares. Suecia, país pionero, considera esencial la participación de los hombres en el cuidado de los hijos como vía para alcanzar la igualdad y por ello defiende una política familiar desarrollada y de calidad.

La política familiar como instrumento de igualdad: distintas concepciones europeas

[ES] Este artículo se centra en el estudio de las políticas familiares que se han implantado en los países de nuestro entorno europeo y sus consecuencias sobre las mujeres en términos de bienestar y de igualdad. La paulatina e irreversible incorporación de las mujeres al mercado de trabajo no solo ha modificado la estructura familiar sino que también ha puesto de manifiesto la estrecha relación entre el trabajo remunerado y el trabajo no remunerado, es decir, el trabajo doméstico y el trabajo de cuidados tanto de la infancia como de las personas dependientes. El objetivo que se persigue es examinar y comparar el grado de compromiso que tienen estos países tanto con el bienestar de la infancia como con la igualdad entre mujeres y hombres, a través de los instrumentos que permiten articular la vida familiar con la vida laboral fomentando la participación masculina en el trabajo de cuidados así como la participación femenina en el empleo remunerado.

Proceedings of the Eighteenth International Sea Turtle Symposium, 3-7 March 1998, Mazatlán, Sinaloa, Mexico

For the first time in its history, the International Symposium on Sea Turtle Biology and Conservation migrated to a site outside of the United States. Thus the Eighteenth edition was hosted by the Mazatlán Research Unit of the Instituto de Ciencias del Mar y Limnología of the Mexican National Autonomous University (UNAM) in Mazatlán, Sinaloa (Mexico) where it was held from 3-7, March, 1998. Above all, our symposium is prominent for its dynamism and enthusiasm in bringing together specialists from the world´s sea turtle populations. In an effort to extend this philosophy, and fully aware of how fast the interest in sea turtles has grown, the organizers paid special attention to bring together as many people as possible. With the tremendous efforts of the Travel Committee and coupled with a special interest by the Latin American region´s devotees, we managed to get 653 participants from 43 countries. The number of presentations increased significantly too, reaching a total of 265 papers, ranging from cutting-edge scientific reports based on highly sophisticated methods, to the experiences and successes of community-based and environmental education programs. A priority given by this symposium was the support and encouragement for the construction of "bridges" across cultural and discipline barriers. We found success in achieving a multinational dialogue among interest groups- scientists, resource managers, decision makers, ngo's, private industry. There was a broad representation of the broad interests that stretch across these sectors, yet everyone was able to listen and offer their own best contribution towards the central theme of the Symposium: the conservation of sea turtles and the diversity of marine and coastal environments in which they develop through their complicated and protracted life cycle. Our multidisciplinary approach is highly important at the present, finding ourselves at a cross roads of significant initiatives in the international arena of environmental law, where the conservation of sea turtles has a key role to play. Many, many people worked hard over the previous 12 months, to make the symposium a success. Our sincerest thanks to all of them: Program committee: Laura Sarti (chair), Ana Barragán, Rod Mast, Heather Kalb, Jim Spotilla, Richard Reina, Sheryan Epperly, Anna Bass, Steve Morreale, Milani Chaloupka, Robert Van Dam, Lew Ehrhart, J.

Once again, Ed Drane worked his usual magic with the Treasury of the Symposium Significant financial contributions were generously provided by government agencies. SEMARNAP (Mexico´s Ministry of Environment, Natural Resources and Fisheries) through its central office, the Mazatlán Regional Fisheries Research Center (CRIP-Mazatlán) and the National Center for Education and Capacity Building for Sustainable Development (CECADESU) contributed to the logistics and covered the costs of auditoria and audiovisual equipment for the Symposium, teachers and their hotels for the Community Development and Environmental Education workshop in the 5th Latin American Sea Turtle Specialists; DIF (Dept of Family Affairs) provided free accomodation and food for the more than 100 participants in the Latin American Reunion. In this Reunion, the British Council-Mexico sponsored the workshop on the Project Cycle. The National Chamber of the Fisheries Industry (CANAINPES) kindly sponsored the Symposium´s coffee breaks. Personnel from the local Navy (Octave Zona Naval) provided invaluable aid in transport and logistics. The Scientific Coordination Office from UNAM (CICUNAM) and the Latin American Biology Network (RELAB) also provided funding. Our most sincere recognition to all of them. In the name of this Symposium´s compilers, I would like to also express our gratitude to Wayne Witzell, Technical Editor for his guidance and insights and to Jack Frazier for his help in translating and correcting the English of contributions from some non-native English speakers. Many thanks to Angel Fiscal and Tere Martin who helped with the typing in the last, last corrections and editions for these Proceedings. To all, from around the world, who generously helped make the 18th Symposium a huge success, shared their experiences and listened to ours, our deepest gratitude! (PDF contains 316 pages)

Pautas de conducta constructiva en psicomotricidad a los dos años

[Es]Este trabajo forma parte de una investigación empírica que aplica la metodología observacional a la incipiente actividad constructiva propia de la psicomotricidad espontánea a los dos años de edad. Es un estudio idiográfico, el diseño observacional utilizado es nomotético, de seguimiento y multidimensional. El instrumento de observación desarrollado ad hoc para el registro de la conducta conscontructiva es el formato de campo “la construcción en psicomotricidad durante el tercer año de vida”. La fiabilidad del instrumento se establece a partir del grado de concordancia entre los observadores. Los resultados, obtenidos mediante el análisis de coocurrencias, informan sobre las condiciones, modalidades, tendencias, evolución y niveles de acción que estas primeras conductas constructivas despliegan. Esta actividad de construcción, de acuerdo con la teoría psicogenética walloniana, puede ser considerada invención de nuevas conductas adecuadas a las nuevas situaciones. Su suspensión da lugar a símbolos enactivos, precursores del juego simbólico infantil.

High-Throughput Sequencing of microRNAs in Peripheral Blood Mononuclear Cells: Identification of Potential Weight Loss Biomarkers

INTRODUCTION: MicroRNAs (miRNAs) are being increasingly studied in relation to energy metabolism and body composition homeostasis. Indeed, the quantitative analysis of miRNAs expression in different adiposity conditions may contribute to understand the intimate mechanisms participating in body weight control and to find new biomarkers with diagnostic or prognostic value in obesity management. OBJECTIVE: The aim of this study was the search for miRNAs in blood cells whose expression could be used as prognostic biomarkers of weight loss. METHODS: Ten Caucasian obese women were selected among the participants in a weight-loss trial that consisted in following an energy-restricted treatment. Weight loss was considered unsuccessful when <5% of initial body weight (non-responders) and successful when >5% (responders). At baseline, total miRNA isolated from peripheral blood mononuclear cells (PBMC) was sequenced with SOLiD v4. The miRNA sequencing data were validated by RT-PCR. RESULTS: Differential baseline expression of several miRNAs was found between responders and non-responders. Two miRNAs were up-regulated in the non-responder group (mir-935 and mir-4772) and three others were down-regulated (mir-223, mir-224 and mir-376b). Both mir-935 and mir-4772 showed relevant associations with the magnitude of weight loss, although the expression of other transcripts (mir-874, mir-199b, mir-766, mir-589 and mir-148b) also correlated with weight loss. CONCLUSIONS: This research addresses the use of high-throughput sequencing technologies in the search for miRNA expression biomarkers in obesity, by determining the miRNA transcriptome of PBMC. Basal expression of different miRNAs, particularly mir-935 and mir-4772, could be prognostic biomarkers and may forecast the response to a hypocaloric diet.

Antioxidant defense system and family environment in adolescents with family history of psychosis

[EN] Our objective was to determine antioxidant defence activity in healthy controls (HC) and healthy unaffected second-degree relatives of patients with early onset psychosis (HC-FHP),and to assess its relationship with familiar environment measured using the Family Environment Scale (FES). Methods: We included 82 HC and 14 HC-FHP aged between 9 and 17 years. Total antioxidant status,lipid peroxidation, antioxidant enzyme activities and glutathione levels were determined in blood samples. Results:There was a significant decrease in the total antioxidant level in the HC-FHP group compared with the HC group (OR = 2.94; p = 0.009), but no between-group differences in the Global Assessment of Functioning (GAF) scale scores. For the FES, the HC-FHP group had significantly higher scores in the cohesion (p = 0.007) and intellectual-cultural dimensions (p=0.025). After adjusting for these two FES dimensions, total antioxidant status remained significantly different between groups (OR = 10.86, p = 0.009).

Cambios oceanográficos y climáticos en el sur del golfo de Vizcaya durante el Cuaternario final, detectados por medio de los foraminíferos y ostrácodos

La microfauna bentónica y planctónica se ha convertido en una herramienta precisa de detección de las variaciones paleoceanográficas y paleoclimáticas. La combinación de grupos faunísticos diferentes, cuya respuesta ante los mismos factores ecológicos puede ser diversa, permite analizar de manera aún más concreta los cambios oceanográficos y climáticos en la misma área de estudio. Así mismo, el estudio de las asociaciones microfaunísticas con técnicas isotópicas y sedimentológicas, posibilitan la determinación del grado de afectación de los parámetros ecológicos considerados en las especies identificadas. La comparación de las variaciones específicas detectadas en el pasado con la distribución de dichas asociaciones en los modelos actuales, permite caracterizar los cambios pretéritos del medio que habitaban estos organismos. El presente trabajo está estructurado en dos bloques principales: por un lado, se estudia la microfauna (foraminíferos bentónicos, planctónicos y ostrácodos) en muestras superficiales de la plataforma, con el objetivo de determinar los parámetros ecológicos que controlan su distribución a lo largo del área de estudio. Por otra parte, se analizan 5 sondeos obtenidos a diferente profundidad, que permiten definir las variaciones oceanográficas y climáticas acontecidas en la plataforma Vasca a finales del Cuaternario, basándonos en los cambios de las asociaciones de microfauna que se suceden a lo largo de los sondeos. Estas variaciones faunísticas denotan, por tanto, cambios ambientales.

An Open and Social Spaced Repetition System for Language Learning

In the last decades big improvements have been done in the field of computer aided learning, based on improvements done in computer science and computer systems. Although the field has been always a bit lagged, without using the latest solutions, it has constantly gone forward taking profit of the innovations as they show up. As long as the train of the computer science does not stop (and it won’t at least in the near future) the systems that take profit of those improvements will not either, because we humans will always need to study; Sometimes for pleasure and some other many times out of need. Not all the attempts in the field of computer aided learning have been in the same direction. Most of them address one or some few of the problems that show while studying and don’t take into account solutions proposed for some other problems. The reasons for this can be varied. Sometimes the solutions simply are not compatible. Some other times, because the project is an investigation it’s interesting to isolate the problem. And, in commercial products, licenses and patents often prevent the new projects to use previous work. The world moved forward and this is an attempt to use some of the options offered by technology, mixing some old ideas with new ones.
