La marginalidad electoral y política de la extrema derecha valenciana (2003-2015)
2017
El partido político España 2000 se auto define como “social patriota” y “anti inmigración” y en su discurso se aprecian elementos de formaciones neo populistas europeas que han obtenido importantes resultados electorales en la última década. Sin embargo, España 2000, tras más de diez años de historia, no ha conseguido el éxito de sus homólogos europeos. Por ello, el texto trata de ofrecer las claves que han favorecido su emergencia y moderado crecimiento en esta región española a través de una metodología cuantitativa y la técnica de inferencia ecológica y a partir de sus datos electorales. El resultado muestra el posible origen de su electorado y las características sociodemográficas de su…
The influence of preparation methodology on the concentrations of heavy metals in Pleurozium schreberi moss samples prior to use in active biomonitor…
2020
AbstractActive biomonitoring is used to assess environmental pollution of elements such as heavy metals by indicator species such as mosses. They are used, among others, in urbanized areas where no indicator species are found. In such study areas, mosses collected from sites considered to be ecologically clean shall be exposed. In this context, it is very important to prepare the mosses properly before the exposure, so that the information received about the condition of the environment is reliable. In 2018, studies were conducted in the forested areas of southern Poland—in Opolskie Province. Pleurozium schreberi mosses were used in these studies. Atomic absorption spectrometry with flame a…
Simultaneous determination of main phenolic acids and flavonoids in tomato by micellar electrokinetic capillary electrophoresis
2017
[EN] A methodology for the determination of tomato phenolic acids and flavonoids has been developed combining MEKC and DAD detection. The influence on polyphenol separation of pH and background electrolyte, BGE (borax, acetonitrile, methanol and SDS concentrations), was studied and optimized using response surface methodology and weighted desirability function. Separation of polyphenols was achieved within 20 min at 15 degrees C using 11.3 mM borax and 11.2 mM SDS adjusted to pH 8.5 as BGE. Validation was performed using standards and tomato extracts. Recoveries ranged from 77 to 106%. Acceptable repeatabilities were obtained for peak area (% RSD <3.1% and <3.7%) and migration times (% RSD …
Estrategias ante el uso de Internet por población usuaria en Atención Primaria: una clasificación sociológica
2021
Resumen: Objetivo: Analizar y clasificar las estrategias comunicativas que desarrollan los/las profesionales de atención primaria de salud de la Comunitat Valenciana ante el uso de Internet como fuente de información de salud por parte de la población usuaria, a través de las categorías analíticas de poder y control que, según Basil Bernstein, caracterizan los procesos de comunicación de los encuentros terapéuticos. Método: Estudio cualitativo mediante entrevistas en profundidad a profesionales de atención primaria de salud de la Comunitat Valenciana (n = 18). Para el análisis de los discursos se ha aplicado el lenguaje de descripción de la teoría de Bernstein con el objetivo de clasificar …
An individual-based dataset of carbon and nitrogen isotopic data of Callinectes sapidus in invaded Mediterranean waters
2022
The characterisation of functional traits of non-indigenous and invasive species is crucial to assess their impact within invaded habitats. Successful biological invasions are often facilitated by the generalist diet of the invaders which can modify their trophic position and adapt to new ecosystems determining changes in their structure and functioning. Invasive crustaceans are an illustrative example of such mechanisms since their trophic habits can determine important ecological impacts on aquatic food webs. The Atlantic blue crab Callinectes sapidus is currently established and considered invasive in the Mediterranean Sea where it has been recorded for the first time between 1947 and 19…
Un estudio sobre la praxis docente del violonchelo en los conservatorios profesionales de la provincia de Valencia / A study about the practice of te…
2016
El presente estudio tiene como objetivo conocer la metodología empleada en la especialidad de violonchelo en los conservatorios de enseñanzas profesionales de la provincia de Valencia. El instrumento de recogida de la información ha sido el cuestionario y la muestra ha estado formada por 34 profesores de 22 conservatorios. Se ha empleado una metodología de complementación, tanto cualitativa como cuantitativa. Los resultados muestran que a pesar de existir algunas coincidencias en la forma y herramientas de trabajo, cada profesor aplica su propia metodología adaptada a las necesidades y características de cada alumno.
De la nécessité d'évaluer les pratiques enseignantes : entre enjeux sociaux et obstacles méthodologiques
2003
This article takes a critical look at the assessment of teaching practices. Firstly, it reminds both principles and methodology whereby school is assessed ; secondly, it mentions social and political issues on which those researches have an effect. Unfortunately, teaching practices are not very much known in France, and so is their efficiency. As a result, significative improvements may be done to develop research on education in France.
An evaluation of the environmental factors for supply chain strategy decisions using grey systems and composite indicators
2020
[EN] The purpose of this work is to assess the importance of environmental factors in a supply chain with four partners as a preliminary step to select the competitive strategies and objectives. To achieve this purpose, a real case study was carried out in a footwear supply chain, in which two approaches were used: the grey system theory and uncertainty analysis tools for composite indicators. In order to validate both approaches, a seven-phase research methodology was developed and applied to our case study. In addition, the priorization of environmental factors was calculated individually for each partner. The results allow managers to establish the competitive strategy that best suits th…
Facebook’s Emotional Contagion Experiment as a Challenge to Research Ethics
2016
This article analyzes the ethical discussion focusing on the Facebook emotional contagion experiment published by the <em>Proceedings of the National Academy of Sciences</em> in 2014. The massive-scale experiment manipulated the News Feeds of a large amount of Facebook users and was successful in proving that emotional contagion happens also in online environments. However, the experiment caused ethical concerns within and outside academia mainly for two intertwined reasons, the first revolving around the idea of research as manipulation, and the second focusing on the problematic definition of informed consent. The article concurs with recent research that the era of social med…
Sensitivity in topic development and meaning making in a process consultation contract meeting
2013
PurposeThe purpose of this paper is to explore the discursive practices used when the agenda for a consultation process was negotiated in a contract meeting. The paper illustrates the role of sensitivity in meaning making practices, that is, how displays of sensitivity were intertwined with topic development.Design/methodology/approachThe paper offers an in‐depth analysis of naturally occurring conversation in a meeting between a consultant and two client managers. The audio‐recorded data is analyzed by utilizing methodology introduced and developed in the traditions of Ethnomethodology and Conversation Analysis (CA).FindingsThe authors show how both the consultant and the clients displayed…
