An examination of parents’ and preschool workers’ perspectives on bullying in preschool
2016
ABSTRACTParents (n = 141) and preschool workers (n = 81) completed a survey regarding their perspectives towards: (a) the existence of bullying in preschool, (b) interpretations of bullying, (c) the roles of bullies and victims, and (d) gender differences. Findings suggest that both groups largely believe that bullying occurs in preschool. Excluding others from play, conditional threats, and the victim's perception of being bullied were the three conditions most likely to be associated with bullying. Parents were significantly more likely than workers to hold a negative view of bullies and believe that bullying differs with regard to gender. Whereas most participants felt that bullying coul…
Collaborative argumentation through role-play by students on a degree programme in social services
2019
The aim of this study was to investigate the nature of collaborative argumentation by students enrolled in a degree program in social services. Students (n = 29) in a University of Applied Sciences participated in role-play discussions and problem solving on adolescents’ substance abuse. The discussions were conducted either online (15 students) or face-to-face (14 students). The data comprise the students’ asynchronous online and face-to-face discussions, which were analysed by identifying discussion fragments relevant in collaborative argumentation, and by comparing the results of the two groups. The results showed that the face-to-face discussions were more collaborative than the online …
Using random networks to study the dynamics of respiratory syncytial virus (RSV) in the Spanish region of Valencia
2011
[EN] Seasonal fluctuations in the incidence of several respiratory infections are a feature of epidemiological surveys all around the world. This phenomenon is characteristic of influenza and respiratory syncytial virus pandemics. However, the explanation of the seasonal outbreaks of these diseases remains poorly understood. Many statistical studies have been carried out in order to provide a correlation of the outbreaks with climatic or social factors without achieving a definitive conclusion. Here we show that, in a random social network, self-sustained seasonal epidemics emerge as a process modulated by the infection probability and the immunity period after recovering from the infection…
La docencia de Estadística en el Grado de Psicología: una experiencia de colaboración interdisciplinar con la asignatura de Psicología Social del Tra…
2011
Se presenta una experiencia de innovación docente fundamentada en la colaboración interdisciplinar entre los estudiantes y profesores de dos asignaturas de la titulación de Psicología de la Universitat de València: Estadística y Psicología Social del Trabajo. De acuerdo a la valoración de los propios estudiantes y de los profesores, esta experiencia ha tenido un efecto positivo en el aprendizaje de los contenidos de ambas asignaturas, a la vez que un importante papel motivador para los estudiantes, estimulándoles a valorar la estadística como una parte integral del proceso de investigación y como un elemento importante de su formación.
Análisis de la realidad sociolingüística del valenciano
2011
Se analiza la situación actual del uso y la percepción social del valenciano entre los habitantes del País Valenciano a partir de los estudios realizados por el Centro de Investigaciones Sociológicas. Para ello, se presta especial atención a variables sociodemográficas a partir de análisis estadístico multivariante con distribuciones de frecuencias bivariadas, análisis de segmentación y regresión logística. El estudio concluye que se produce un estancamiento en el porcentaje de hablantes del valenciano y que las personas de izquierdas y con mayor nivel de estudios son quienes se postulan más a favor de la unidad del valenciano con el catalán. Palabras clave: sociolingüística; diglosia; esta…

A typology of theatre audiences based on the impact of various sources of influence and the use of information channels
2020
En: Doxa Comunicación: revista interdisciplinar de estudios de comunicación y ciencias sociales. e-ISSN 2386-3978 n. 30, 2020, pp 127-143. Este estudio presenta una tipología de espectadores teatrales que contempla la influencia de los medios de comunicación y otras instancias de prescripción en sus decisiones de asistencia al teatro, un aspecto no abordado por ninguna investigación previa. La investigación se basa en una encuesta a 210 asistentes a representaciones teatrales de tres salas de la ciudad de Valencia. La aplicación de diversas técnicas estadísticas multivariables ha permitido identificar una tipología de cuatro perfiles de consumidores escénicos: los informados-alternativos, l…
RANKING DECISION MAKING UNITS BY MEANS OF SOFT COMPUTING DEA MODELS
2011
This paper presents a method for ranking a set of decision making units according to their level of efficiency and which takes into account uncertainty in the data. Efficiency is analysed using fuzzy DEA techniques and the ranking is based on the statistical analysis of cases that include representative situations. The method enables the removal of the sometimes unrealistic hypothesis of a perfect trade-off between increased inputs and outputs. This model is compared with other DEA models that work with imprecise or fuzzy data. As an illustration, we apply our ranking method to the evaluation of a group of Spanish seaports, as well as teams playing in the Spanish football league. We compar…
Insights from Operator Interviews
2009
The previous section analysed use of software to improve productivity from a general perspective and provided a quick statistical analysis of software usage to the performance of a CSP. Before conducting elaborated statistical analysis on CSP software usage, we need to gain some insight into operator business and understanding on how operators see the role of software in their business as well as how they acquire software.
Numerical study of soliton stability, resolution and interactions in the 3D Zakharov–Kuznetsov equation
2021
International audience; We present a detailed numerical study of solutions to the Zakharov-Kuznetsov equation in three spatial dimensions. The equation is a three-dimensional generalization of the Korteweg-de Vries equation, though, not completely integrable. This equation is L-2-subcritical, and thus, solutions exist globally, for example, in the H-1 energy space.We first study stability of solitons with various perturbations in sizes and symmetry, and show asymptotic stability and formation of radiation, confirming the asymptotic stability result in Farah et al. (0000) for a larger class of initial data. We then investigate the solution behavior for different localizations and rates of de…
