Conocimiento y cobertura vacunal autodeclarada en inmigrantes adultos residentes en la provincia de Alicante

Introducción: Existe una estimable probabilidad de cobertura vacunal insuficiente entre la población inmigrante. Los estudios realizados se centran en población infantil. Este trabajo explora la opinión y conocimientos sobre vacunas, así como la cobertura vacunal autodeclarada en población adulta inmigrante en edad laboral. Métodos: Estudio transversal basado en un cuestionario específico dirigido a inmigrantes entre 18-65 años residentes en la provincia de Alicante. Se realizó mediante entrevista personal a una muestra de 692 individuos entre febrero y abril de 2010. Resultados: Del total de encuestados, un 56,6% son mujeres, el 90,8% reside en España desde hace menos de 10 años y un 88,7% dispone de tarjeta sanitaria. Las comunidades rumanas y marroquíes son las que menos confianza muestran hacia las vacunas. Las más conocidas son las del tétanos (65,8%), la gripe (56,8%) y la hepatitis B (56,2%); a su vez, las más administradas son las del tétanos y la hepatitis B (entre los marroquíes), y la antigripal (entre los europeos). El colectivo marroquí es el peor vacunado en su país de origen y el que más vacunas ha recibido en España (1,3 vacunas/persona). Un 46,7% refiere haber sido inmunizado alguna vez en España, aconsejados principalmente en su centro de salud o el lugar de trabajo. Un 13,3% del colectivo rumano y un 4,7% del ecuatoriano declararon haber tenido alguna dificultad para ser vacunados. Conclusiones: Aunque existe una opinión general favorable hacia las vacunas, algunas nacionalidades muestran cierta indiferencia o desapego. El estado vacunal y la predisposición a vacunarse difiere entre nacionalidades. Sería muy conveniente reforzar la tarea realizada por los equipos de atención primaria y aprovechar las ocasiones que representa la visita a un centro sanitario para ampliar la cobertura vacunal del colectivo de inmigrantes adultos.

Evolution of extracellular polymeric substances produced in two submerged membrane bioreactors working at high sludge age

This research paper deals with the evolution of the extracellular polymeric substances (EPS) produced in the mixed liquor of two 25 L bench-scale membrane bioreactors (MBRs), with micro (MF-MBR) and ultrafiltration (UF-MBR) submerged membranes. The conclusion focuses on the relationship between the operation and how EPS respond, demonstrating that significant changes in EPS concentration were commonly observed when abrupt changes in the operational conditions took place. Bound EPS (EPSb) showed moderate positive statistical correlations with sludge age and MLSS for the two MBRs. Soluble EPS (EPSs), on the other hand, showed a moderate negative statistical correlation between EPSs with the two parameters analyzed for MF-MBR and no correlation with the UF-MBR was found. With respect to the composition of EPS, EPSb were mostly made up of proteins (44–46%) whereas in EPSs, the three components (proteins, carbohydrates, and humic substances) appeared in approximately the same proportion. The statistical analysis exhibited strong positive correlations between EPSb and their constituents, however for EPSs, the correlation was strong only with carbohydrates and moderate with humic substances.

Technical efficiency in the retail food industry: the influence of inventory investment, wage levels, and age of the firm

The objective of this paper is to estimate technical efficiency in retailing; and the influence of inventory investment, wage levels, and firm age on this efficiency. We use the output supermarket chains’ sales volume, calculated isolating the retailer price effect on its sales revenue. This output allows us to estimate a strictly technical concept of efficiency. The methodology is based on the estimation of a stochastic parametric function. The empirical analyses applied to panel data on a sample of 42 supermarket chains between 2000 and 2002 show that inventory investment and wage level have an impact on technical efficiency. In comparison, the effect of these factors on efficiency calculated through a monetary output (sales revenue) shows some differences that could be due to aspects related to product prices.

Looking Forward to a Dynamic Third Age - Comparative Survey Report

BALL (Be Active Through Lifelong Learning) is an Erasmus + project of the European Union with the chief objective of analysing the degree of Preparation for Retirement among European citizens. The team working for this project, funded by the EU, is composed by organizations with broad experience at work with the third age from three European countries, Poland, Iceland and Spain, and the results obtained from these three contexts aim to provide a clear picture about the state of the art in preparation for retirement nowadays. The main objective of the project is to develop innovative guidelines and recommendations for use at lifelong learning centres; universities; companies; unions; associations; local and regional authorities who need and wish to prepare and encourage individuals under their auspices to prepare for the third age. The project defines the age group of 50 to 70 (the “baby boomer” generation) as the target group for such early preparations. The project and its outcomes will be used to raise awareness of these important issues and disseminate the results throughout the European Educational Area and the worldwide U3A network.
