    En este artículo se da cuenta de uno de los estudios realizados en la Comunidad Canaria en torno a los principales servicios de apoyo externo a los centros educativos, en concreto el referido a los CEP. Se pretendían dos objetivos: la obtención de conocimiento para comprender mejor la naturaleza, funciones, modelos de actuación y condiciones en que se desempeña la labor de asesoramiento; y, la detección de los problemas y necesidades más importantes, ofreciendo recomendaciones para su mejora. Se recogió información, mediante cuestionarios, tanto de los asesores como del profesorado. Las principales conclusiones apuntan a la existencia de un doble divorcio: 1) entre lo que los asesores piensan que deben hacer (funciones más relacionadas con los procesos de desarrollo y mejora de los centros y con la capacitación de las escuelas y el desarrollo profesional del profesorado) que con lo que hasta la fecha han hecho (cubrir las necesidades derivadas del proceso de implantación de la LOGSE, especialmente en el diseño y desarrollo de cursos y en la divulgación de la normativa); 2) entre lo que los asesores creen que hacen y lo que el profesorado percibe de ellos. Se sugiere que los CEP deben retomar su idea original de instituciones al servicio del profesorado y los centros, adquiriendo una mayor autonomía de la Administración.En aquest article s'informa d'un dels estudis realitzats a la Comunitat Canària al voltant dels principals serveis de suport extern als centres educatius, en concret el referit als Centres de Professors (CEP). Es pretenien dos objectius: l'obtenció de coneixement per a comprendre millor la naturalesa, funcions, models d'actuació i condicions en les que es porta a terme la tasca d'assessorament; i, la detecció de les problemàtiques i necessitats més importants, oferint recomanacions per a la seva millora. Es va recollir informació, mitjançant qüestionaris, dels assessors i dels professors. Les principals conclusions apunten a l'existència d'un doble divorci: 1) entre el que els assessors pensen que han de fer (funcions més relacionades amb els processos de desenvolupament i millora dels centres i amb la capacitació de les escoles i el desenvolupament professional del professorat) amb el que fins a la data han fet (cobrir les necessitats derivades del procés d'implantació de la LOGSE, especialment en el disseny i desenvolupament de cursos i en la divulgació de la normativa); 2) entre el que els assessors creuen que fan i el que el professorat percebeix d'ells. Se suggereix que els CEP han de reprendre la seva idea original d'institucions al servei del professorat i dels centres, adquirint una més gran autonomia de l'Administració.In this article we present the results of one of the studies developed about the external support systems to the schools in Canary Islands, especially the one refered to the Teachers' Centers. The study aimed to the following main purposes: to gather information about Teachers' Centers in order to reach a better understanding of the nature, functions, performance models and work conditions of school consultants, and to identify the main needs and problems thei are facing, offering at the time some suggestions for improvement. The main conclusions point to a double divorce 1) between what the school consultants think they should be doing (this is, functions related to school development and improvement, and to teachers' empowement and professional development) and what they are doing to the date (meeting needs related to the process of implementation of the 1990 Educational Act, mainly working in the designing and development of trainning courses for teachers and the dissemination of legal regulations related to the Educational Act); and 2) between what the school consultants think they are doing and what the techaers perceived abouy it. It is suggested that Teachers' Centers should recover the original idea becoming institutions at the service of teachers and schools, geeting more autonomy in their functioning from the Regional Educational Authorities

    Motivation: The use of pesticides in the modern agriculture has meant an improvement in the conditions and production of crops. However, the continuous use has led to contamination problems in soils, water and sediments affected by its application. One of the pesticides widely used to fight against insect pests is the chlorpyrifos. This organophosphate pesticide produces a metabolite known as triclhoro-2-pyridinol (TCP) which presents a high toxicity increasing the risk of environmental toxicity. The current study was carried out to assess the effect of native microorganisms from an agricultural soil contaminated by chlorpyrifos in the bioremediation of soils contaminated with this pesticide.  Methods: The soil sample was collected from a private property where chlorpyrifos was commonly used that was located in Roche, in the southern Cadiz. In order to isolate degrading bacterial strains from the soil treated with chlorpyrifos, enrichment technique with mineral salt medium (MSM), a nutrients solution and using the insecticide as the only carbon source was employed. Subsequently, potential CLP bacteria strains degraders were isolated from the microbial consortium, initially isolated. Biological oxygen demand (BOD) assays were performed with the aim of determining which bacterial strains were capable to biodegrade chlorpyrifos. Once the BOD results were obtained, the samples were analysed by the gas chromatography-mass spectrometry to measure the insecticide concentration present in the solution, after the assay.Results:  A total of 21 bacterial strains were isolated from the enrichment mediums. From these strains, nine of them reached values of 50 mg O2 L-1 in BOD assays. These values were relevant to continue with the analysis of the solution from the samples in the gas chromatography-mass spectrometry. The degradation studies with gas chromatography-mass spectrometry where the concentration of supernatants from the BOD assays were analysed with the 197-ion extraction, indicated that R13A strain was able to degrade 70% of chlorpyrifos within 384 hours.Conclusions: In the present work, the effect of microbial population in the treatment of a soil that had received continuous applications of chlorpyrifos was determined. The R13A strain isolated from soil has shown promising results in the preliminary assays of biodegradation

    Introduction: Flexor tendon injuries in children represent a diagnostic and therapeutic challenge for the surgeons involved in the treatment. These Injuries go unnoticed, directed rehabilitation is difficult but good results are achieved during follow-up. The objective of this study is to describe the clinical characteristics of a series of pediatric patients with injuries of flexor tendons of the hand and their functional results. Materials and methods: This is a retrospective study of patients with flexor tendon injuries over a two-year period. Variables analyzed were: age, sex, laterality, trauma mechanism, affected area, associated lesions and results with TAM scale. Inclusion criteria: age 0-16 years, diagnosis of flexor lesion and minimum follow-up of 10 weeks. Results: Twenty-one patients were found, 15 of them had a cutting injury. One case had bilateral involvement. Zone V was the most affected in all cases, followed by zone II. The most frequent associated lesions were colateral nerve and ulnar nerve injuries. Short-term results were good in most patients. Conclusions: A high index of suspicion is necessary for the diagnosis of these lesions; In pediatric patients, surgical exploration is recommended in case of clinical suspicion of tendinous lesion. Primary repair is the gold standard of treatment and the results are good with an adequate follow-up and immobilization protocol

    La conciliación laboral y familiar y la organización de la jornada laboral. El caso de Tenerife.

    Get PDF
    El objetivo de este trabajo es ofrecer una perspectiva reciente de diversos aspectos relativos a la conciliación familiar y laboral y mostrar cuál es la situación actual en Tenerife en esta materia. Con este fin, se ha revisado legislación e informes de distinto tipo y, además, se ha realizado una encuesta en la que se pregunta sobre esta problemática. Entre las conclusiones alcanzadas cabe señalar la preocupación por la conciliación tanto a nivel político como social, si bien no se ha avanzado lo suficiente en este aspecto. Así, aunque haya una mayor flexibilidad en términos de organización de la jornada laboral que antes, la jornada completa dificulta la conciliación. Las mujeres son las más perjudicadas porque se siguen encargando mayoritariamente del cuidado de otras personas. Específicamente, la atención a los hijos es una dificultad importante, ya que, al menos en Tenerife, no hay suficientes guarderías públicas.The aim of this paper is to offer a recent perspective on various aspects related to work-life balance and to show the current situation in Tenerife in this area. To this end, different types of legislation and reports have been reviewed and, in addition, a survey has been carried out in which questions have been asked about this issue. Among the conclusions reached, it is worth mentioning the concern for work-life balance at both political and social levels, although not enough progress has been made in this area. Thus, although there is greater flexibility in terms of the organisation of the working day than in the past, the full working day makes work-life balance more difficult. Women are the most disadvantaged because they are still mostly responsible for caring for other people. Specifically, childcare is a major difficulty, since, at least in Tenerife, there are not enough public nurseries

In this area have been developed a variety of methods, strategies and activities to approach this target language to increase the learning of the English language fast. It also includes teaching approaches, didactic resources and learning styles. In Nicaragua`s public schools there are many difficulties with the teaching of the English as a foreign language in secondary school and this research provides a lot of information that can help the teacher to improve the English teaching and develop speaking skills. It can improve the reliability and effectiveness of the teaching – learning process. This work is supported by survey answered by the students and the collaboration of the teacher and the principal of the Jose Augusto public schoo

    First derivative-supervised pattern recognition for the flow-injection spectrophotometric discrimination of s-triazines in water

    Get PDF
    A new spectrophotometric method is presented for the automated differentiation of chloro- (0.5 to 5.0 mg/mL), thio- (0.5 to 5.0 mg/mL) and methoxy-triazines (1 to 10 mg/mL) in water samples. Classification models obtained by K-nearest neighbours, Soft Independent Modeling of Class Analogy, and Partial Least Squares-Discriminatory Analysis were constructed from zero order and first derivative absorption spectra as independent variables, in the spectral range from 210 to 270 nm. Binary responses were used as classifying variables (with/without certain group of triazines). With this dichotomous structure, parameters related to 2x2 contingency tables were used to evaluate the performance of the models. For tap and well water samples, sensitivity and selectivity values equal or higher than 50 % were obtained from autoscaled first derivative spectra, discriminated by Partial Least Squares-Discriminatory Analysis
