Las elecciones autonómicas de 1999 y las Españas electorales
2000
En las siguientes paginas se estudian las principales caracteristicas de los sistemas y subsistemas de partidos surgidos de la ultima convocatoria electoral de caracter autonomico. Se analizan los datos que en cada Comunidad Autonoma alcanzan la fragmentacion, el numero de partidos, la concentracion, la competitividad, la polarizacion y la volatilidad, y se comparan con los valores que estas dimensiones alcanzan en otras Comunidades Autonomas, asi como con los registrados en anteriores convocatorias. En la conclusion se senalan los distintos sistemas y subsistemas, modelo general y excentricos, que pueden distinguirse en atencion a las respectivas caracteristicas de las pautas de la competi…
Quality control for exposure assessment in epidemiological studies
2010
In the framework of an epidemiological study, dosemeters were used for the assessment of radio frequency electromagnetic field exposure. To check the correct dosemeter's performance in terms of consistency of recorded field values over the entire study period, a quality control strategy was developed. In this paper, the concept of quality control and its results is described. From the 20 dosemeters used, 19 were very stable and reproducible, with deviations of a maximum of +/- 1 dB compared with their initial state. One device was found to be faulty and its measurement data had to be excluded from the analysis. As a result of continuous quality control procedures, the confidence in the meas…
Analysis of fumonisins B1, B2 and B3 in corn-based baby food by pressurized liquid extraction and liquid chromatography/tandem mass spectrometry
2008
A sensitive and reliable method using pressurized liquid extraction (PLE) and liquid chromatography (LC)/electrospray ionization (ESI) tandem mass spectrometry with a triple quadrupole (QqQ) analyzer has been developed for the analysis of fumonisin B(1) (FB(1)), fumonisin B(2) (FB(2)) and fumonisin B(3) (FB(3)) in corn-based baby foods. Influence of several extraction parameters that affect PLE efficiency such as temperature, pressure, solvent extraction, number of cycles and dispersant/clean-up agents were studied. The selected PLE operating method was: 3g of sample was packed into 11 ml stainless-steel cell and fumonisins were extracted with methanol at 40 degrees C, 34 atm in one cycle o…
Nanoelectrospray with ion-trap mass spectrometry for the determination of beta-casomorphins in derived milk products.
2009
Beta-casomorphins (b-CMs) are bioactive peptides derived from casein with opioid agonist effects similar to morphine. The use of electrospray (ESI) with quadrupole ion-trap mass spectrometry (QIT-MS) for these compounds in two matrices, cheese and milk, was examined. It was compared to a liquid chromatography (LC) coupled to mass spectrometry (LC-MS), and a "soft" ionisation technique, NanoMate, with selected ion monitoring (SIM), which are unreliable for the determination of trace casomorphins in derived milk products. b-CM mass fragmentation pathways were done for the four most common b-CMs: beta-casomorphin (1-5) bovine (b-CM-5), beta-casomorphin (1-7) bovine (b-CM-7), [D-Ala2, D-Pro4,Ty…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
1993
Resumen basado en el de la publicación Resumen en inglés ¿La educación sanitaria es lo mismo que la educación para la salud? ¿Qué factores hay que tener en cuenta al configurar un plan de estudios para la educación de la salud? ¿Es necesario tratar asuntos de salud tales como higiene, vacunaciones, etc., para desarrollar este tipo de educación para las escuelas? Estas son solo algunas de las preguntas que se plantean y se muestra el uso de fuentes que determinan un plan de estudios, como en el caso específico de Alimentación-Nutrición. ESP
Group analytic therapy for eating disorders: preliminary results in a single-group study.
2008
Objectives There is a lack of empirical data on the effectiveness and process of group-analytic therapy in eating disorders. This single-group study aimed to explore the effectiveness of such treatment for anorexic and bulimic individuals. Method Eight patients (three anorexic and five bulimic women) entered group-analytic treatment, meeting weekly for 2 years. Eating behaviours, overall psychological distress and group process variables were regularly assessed using quantitative and qualitative measures, with comparisons made at the beginning and end of the therapy. Results Treatment was discontinued in two cases. When outcome was classified on the basis of reliable change and clinical sig…
Resultado económico y de empleo en las organizaciones sociales de origen familiar
2018
La Unión Europea ha apostado por el modelo de empresa social como una herramienta para corregir los desequilibrios socioeconómicos en los países miembros. En el contexto de la economía española, las organizaciones familiares destacan debido a su fuerte presencia y apoyo. El objetivo de este trabajo es estudiar la relación entre el rendimiento económico y el nivel de empleo, como indicador de impacto social, en las organizaciones aragonesas de origen familiar, así como las diferencias en esta interacción cuando la forma lucrativa o no lucrativa de la estructura formada por la unidad familiar se introduce como variable moderadora. Para ello, se obtuvo una muestra de 2.931 empresas y 117 funda…
Transcultural adaptation and validation of Italian Selfcarediabetic foot questionnaire
2021
[Abstract] The Italian Self care diabetic foot questionnaire, (SDFQ-IT) is considered a dia-betic foot self-care evaluation tool with 16 questions for assessing diabetic foothealth disorders. To date, SDFQ has been validated in different languages, butan Italian version was lacking. Consequently, the purpose of this study was totranslate and validate the Italian version of the SDFQ-I T (SDFQ-IT). A suitablemethod was developed for the translation protocol and cross-cultural valida-tion from Spanish to Italian. Regarding the total marks from each sub-scale,agreement degrees, and confidence were analysed using the Cronbach's α andintraclass correlation coefficient (IC C), respectively. In add…
Analytical Performance and Validation of a Bioassay for Thyroid-Blocking Antibodies
2016
A cell-based bioassay for the measurement of thyroid blocking autoantibodies (TBAb) has been recently reported. The analytical performance and validation of this bioassay is assessed and described.Chinese hamster ovary cells expressing a chimeric thyrotropin receptor were treated with bovine (b) TSH and different concentrations of an immunoglobulin G (IgG) monoclonal human TBAb (K1-70). TBAb was measured as a function of luciferase activity relative to bTSH alone and expressed as percent inhibition. Results obtained in the chimeric cell line were compared with those of a wild-type cell line. Analytical performance studies were subsequently performed with the chimeric cell line only.Immunode…
A mixed FES/EMG system for real time analysis of muscular fatigue
2010
International audience; In this article, we present a functional electrical stimulator allowing the extraction in real time of M-wave characteristics from resulting EMG recodings in order to quantify muscle fatigue. This system is composed of three parts. A Labview software managing the stimulation output and electromyogram (EMG) input signal, a hardware part amplifying the output and input signal and a link between the two previous parts which is made up from input/output module (NIdaq USB 6251). In order to characterize the fatigue level, the Continuous Wavelet Transform is applied yielding a local maxima detection. The fatigue is represented on a scale from 0 for a fine shaped muscle to …
