Trabajadores mayores con discapacidad: Diferencias de satisfacción laboral en el sector público y el sector privado en Europa

Análisis de las diferencias en satisfacción laboral de las personas mayores con y sin discapacidad europeas (entre 50 y 64 años) que se encuentran empleadas en el sector público o privado. Usando los datos suministrados por la Survey of Health, Ageing and Retirement in Europe (SHARE) para los años 2004 y 2007, se estiman ecuaciones de satisfacción laboral con técnicas de panel para los trabajadores del sector público y sector privado, las cuales incluyen variables relacionadas con el grado de discapacidad del trabajador (es decir, no discapacitado, discapacitado no limitado y discapacitado limitado). Los resultados muestran que aunque los trabajadores discapacitados limitados en sus actividades diarias están menos satisfechos que los no discapacitados y no limitados en ambos sectores, éstos poseen unos mayores niveles de satisfacción laboral cuando trabajan en el sector público que cuando lo hacen en el sector privado. Desde un punto de vista de políticas públicas es necesario diseñar y acometer medidas y acciones que contribuyan a mejorar los niveles de satisfacción laboral de los trabajadores mayores con discapacidad, en especial entre aquellos que están limitados en sus actividades diarias.Universidad de Málaga.

COVID-19: Recomendaciones técnicas sobre el correcto uso de equipos agrícolas en los espacios públicos para la aplicación de soluciones de Cloro

La evidencia actual sugiere que el COVID-19 (SARS-CoV-2) puede permanecer viable durante horas o días en la superficies de distintos tipo de materiales. La limpieza de las mismas visiblemente sucias seguida de desinfección es una medida de mejores prácticas para la prevención de COVID-19 y otras enfermedades respiratorias virales en hogares y entornos comunitarios. En tal sentido, se sugiere, el presente protocolo para el caso de utilizar pulverizadoras comerciales de fitosanitarios para la desinfección de espacios de uso público, cada vez que el Ministerio de Salud y/o sus Dependencias o Comités de Emergencia así lo decidan. Se identifica como el desinfectante de uso más común, una solución en base a hipoclorito de sodio (cloro). Al respecto y a los efectos de lograr la máxima eficacia y eficiencia en la aplicación, siendo el objetivo básico de la misma llegar al blanco (virus) en el momento adecuado, con la cantidad de producto desinfectante adecuado recomendado por las autoridades de salud competentes.Instituto de Ingeniería RuralFil: Martens, Silvia Fanny.

Bienestar psicológico, salud general, autonomía percibida y lesiones en futbolistas

Given the concern with the practice of healthy sport activities, the aim of this study is to find what levels of eudaimonic psychological well-being (Ryff, 1989a) and general health, related with their perceived autonomy, and their record of sports injuries in 85 football players in Mexico. We used the Escala de Bienestar Psicológico, EBP, Díaz et al., 2006 to measure psychological well-being. Perceived autonomy was assessed by the Escala de Autonomía Percibida en el Deporte (Balaguer, Castillo and Duda, 2008) and general and emotional health by the Spanish version (Sánchez and Dresch, 2008) of the 12-item General Health Questionnaire (GHQ-12, Goldberg and Hillier, 1979). Also, records of injuries were assessed using an ad hoc questionnaire derived from the Global psychological model of sports injuries (Olmedilla and Garcia-Mas, 2009). The results show that players have a bad perception of general and emotional health, but have good levels of psychological well-being in relation to their perceived autonomy. The number of injuries -not their duration- is related to their poor perception of general and emotional health while it is negatively related to the volitional aspect of perceived autonomy. Their injuries are seen to be frequently associated with pre-competitive anxiety and stress

Mapping of Genetic Abnormalities of Primary Tumours from Metastatic CRC by High-Resolution SNP Arrays

This is an open-access article distributed under the terms of the Creative Commons Attribution License.-- et al.[Background]: For years, the genetics of metastatic colorectal cancer (CRC) have been studied using a variety of techniques. However, most of the approaches employed so far have a relatively limited resolution which hampers detailed characterization of the common recurrent chromosomal breakpoints as well as the identification of small regions carrying genetic changes and the genes involved in them. [Methodology/Principal Findings]: Here we applied 500K SNP arrays to map the most common chromosomal lesions present at diagnosis in a series of 23 primary tumours from sporadic CRC patients who had developed liver metastasis. Overall our results confirm that the genetic profile of metastatic CRC is defined by imbalanced gains of chromosomes 7, 8q, 11q, 13q, 20q and X together with losses of the 1p, 8p, 17p and 18q chromosome regions. In addition, SNP-array studies allowed the identification of small (1.5 Mb) altered DNA sequences, many of which contain cancer genes known to be involved in CRC and the metastatic process. Detailed characterization of the breakpoint regions for the altered chromosomes showed four recurrent breakpoints at chromosomes 1p12, 8p12, 17p11.2 and 20p12.1; interestingly, the most frequently observed recurrent chromosomal breakpoint was localized at 17p11.2 and systematically targeted the FAM27L gene, whose role in CRC deserves further investigations. [Conclusions/Significance]: In summary, in the present study we provide a detailed map of the genetic abnormalities of primary tumours from metastatic CRC patients, which confirm and extend on previous observations as regards the identification of genes potentially involved in development of CRC and the metastatic process.This work has been partially supported by grants from the Consejeria de Sanidad, Junta de Castilla y Leon, Valladolid, Spain (SAN191/SA09/06 and SAN673/SA39/08), Fundacion Memoria de Don Samuel Solorzano Barruso, Salamanca, Spain, Caja de Burgos (Obra Social), Burgos, Spain, Grupo Excelencia de Castilla y Leon (GR37) and the RTICC from the Instituto de Salud Carlos III (ISCIII), Ministerio de Ciencia e Innovacion, Madrid, Spain (RD06/0020/0035-FEDER).

Chemical and Physical Defense Traits in Two Sexual Forms of Opuntia robusta in Central Eastern Mexico

In this study, we showed that the seed output is higher in hermaphrodites than in females of O. robusta but also has a higher variance. Furthermore, the hermaphrodite sexual form is on average spinier than the female form, and reproductive cladodes are spinier in hermaphrodites than in females. In addition, we showed that hermaphrodite empty cladodes contain a higher concentration of phenolic compounds than female empty cladodes and found a possible trade-off between the production of phenolic compounds in parental cladodes and their content in daughter cladodes. There also was a possible trade-off between the density of spines on areolae and average number of areolae per cladode, and a positive relationship between physical and chemical defense traits. With the current data, we cannot conclude that sexual polymorphism in the study population is herbivore mediated. In addition, we cannot make inferences about the possible evolution from gynodioecy to dioecy in O. robusta because of the need for accurate information concerning the costs of inbreeding, the entire costs of reproduction, the lifetime reproductive success, the estimation of vegetative growth traits, and possible competition for pollinators with other plant species.Sexually dimorphic plants provide an excellent opportunity for examining the differences in the extent of their defense against herbivores because they exhibit sex-related differences in reproductive investment. Such differences enable comparison of the sex with high reproduction expenses with the sex that expends less. The more costly sex is usually also better defended against herbivores. Generally, females are considered more valuable than hermaphrodites in terms of fitness; however, hermaphrodites are more valuable if they can produce seed by autonomous selfing, provided that the inbreeding depression is low and pollen is limited. We studied a gynodioecious population of Opuntia robusta from Central- Eastern Mexico, which has been reported to be trioecious, dioecious, or hermaphrodite, and addressed the following questions: 1) Is the hermaphrodite’s reproductive output higher than the female’s, and are hermaphrodites thus better defended? 2) Are plant tissues differentially defended? 3) Do trade-offs exist among different physical defense traits? and 4) among physical and chemical defense traits? We found that 1) hermaphrodites had a higher seed output and more spines per areola than females and that their spines contained less moisture. Non-reproductive hermaphrodite cladodes contained more total phenolic compounds (TPCs) than female ones. In addition, 2) hermaphrodite reproductive cladodes bore more spines than female cladodes, and 3) and 4) we found a negative relationship between spine number per areola and areola number per cladode and a positive relationship between spine number per areola per plant and TPC concentration per plant. Non-reproductive hermaphrodite cladodes contained a higher concentration of TPCs than female cladodes, and parental cladodes contained fewer TPCs than both reproductive and empty cladodes.UAEM project 2823/2009U CONACyT project 180694/201

Patterns of Spiny Lobster (Panulirus argus) Postlarval Recruitment in the Carribbean: A CRTR Project

As part of the Coral Reef Targeted Research (CRTR) Program, a partnership between the Global Environment Facility and the World Bank, our research team examined the recruitment patterns of Caribbean spiny lobster (Panulirus argus) postlarvae among regions in the Caribbean, with a particular focus on Mesoamerica. Our goal was to collect comparable information on postlarval supply among regions and to provide data to test predictions of connectivity generated from a coupled biophysical oceanographic model of lobster larval dispersal. Here we present the results of the postlarval recruitment monitoring program. We monitored the catch of postlarvae on Witham-style collectors at sites in the Caribbean from March 2006 to May 2009, although the duration and frequency of sampling varied among locations. Recruitment varied considerably among months and locations. It peaked in the Western Caribbean in the fall (Oct - Dec), whereas in Florida, Puerto Rico, and Venezuela peaks were in spring (Feb - April) with a smaller peak in the fall. Sites generally fell into two groups with respect to monthly variability in recruitment: low variability sites (e.g., Honduras, southern Mexico, Venezuela) and high variability sites (e.g., Florida, San Andres Islands, Puerto Rico, northern Mexico). Recruitment magnitude varied locally, but generally increased (lowest to highest) from Puerto Rico, San Andres Islands, Honduras, Mexico, Venezuela, to Florida. Recruitment trends mirrored fishery catch in some locations, implying a recruit-to-stock linkage. Recruitment was significantly correlated among several sites, suggesting similarity in their larval sources and oceanographic regimes
