Prevalence of the bullying phenomenon in a schools sample of Palermo, Sicily: a pre-post intervention observational study among teachers
2018
Background and aim of the work: Bullying involves a significant percentage of school-age children. According to the latest available surveillance data, in Sicily, the estimated prevalence among 11-15 years old children is 14%. This study aimed to estimate a prevalence of the bullying phenomenon, observed by teachers, in a sample of secondary schools of Palermo, Sicily. Moreover, after the conduction of preventive interventions among teachers, aimed to evaluate any modification in bullying prevalence. Methods: A cluster sampling selection according to socio-economic level of the school neighborhood was carried out. Two anonymous online questionnaires, pre and post-intervention, were administ…
Development of a Brief Multicultural Version of the Test of Mobile Phone Dependence (TMDbrief) Questionnaire
2016
The Test of Mobile Phone Dependence (TMD) questionnaire (Chóliz, 2012) evaluates the main features of mobile phone dependence: tolerance, abstinence syndrome, impaired impulse control, associated problems, excessive use, etc. Objective: The objective of this study was to develop a multicultural version of the TMD (TMDbrief) adapted to suit the novel communication tools of smartphones. Procedure: In this study, the TMD was completed by 2,028 young respondents in six distinct world regions: Southern Europe, Northwest Europe, South-America, Mesoamerica, Pakistan, and India. Results: Psychometric analysis of the reliability of the instrument and factor analysis were performed to adapt the TMDbr…

Revista electrónica de investigación y evaluación educativa
2018
La victimización en la escuela representa un fenómeno preocupante dado las consecuencias negativas que se le asocian, como son estados de depresión o ansiedad, los cuales guardan relación con los hábitos de ocio digital. Se realizó un estudio descriptivo de tipo transversal, realizado en una muestra de 1038 escolares de tercer ciclo de Educación Primaria (M = 11,33; DT = 1,27), el cual persigue como principal objetivo contrastar un modelo explicativo del uso de televisión y videojuegos en función de la victimización. Se emplearon como principales instrumentos la Escala de Victimización en la Escuela (Mynard y Joseph, 2000), el Cuestionario de Experiencias Relacionadas con Videojuegos (Chama…
Educación artística : revista de investigación
2016
La tecnología multiplica los espacios donde ocurre la relación pedagógica. Determinadas temáticas en la universidad, como los procesos de reflexión sobre las preconcepciones, permiten en este trabajo analizar una actividad crítica de la formación inicial de docentes. También pensar, simultáneamente, sobre una relación pedagógica ampliada. Los autores dialogan, con sus experiencias de varios años inmersos en este tipo de prácticas, sobre el propósito, las limitaciones, los resultados y la toma de conciencia sobre la profesión. Se han generado actividades de debate mediante foros, tutelados por ellos, en varias materias para la formación de maestros: unas de tipo pedagógico y otra que es el s…
Indistinguishability of Elementary Systems as a Resource for Quantum Information Processing.
2017
Typical elements of quantum networks are made by identical systems, which are the basic particles constituting a resource for quantum information processing. Whether the indistinguishability due to particle identity is an exploitable quantum resource remains an open issue. Here we study independently prepared identical particles showing that, when they spatially overlap, an operational entanglement exists which can be made manifest by means of separated localized measurements. We prove this entanglement is physical in that it can be directly exploited to activate quantum information protocols, such as teleportation. These results establish that particle indistinguishability is a utilizable …
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
The Case of Insertional Adductor Tendinopathy of an International-Level 3,000-m Steeplechase Runner
2021
Background: Groin pain is a frequent condition among athletes. One of the causes of groin pain is tendinopathy, a frequently diagnosed medical condition, which can also occur in the adductor muscles. Despite the high prevalence of this medical condition among athletes, it is infrequent to observe tendinopathic groin pain in steeplechase runners. The aim of this case study is to describe the case of an international-level 3,000-m steeplechase runner with groin pain, who was subsequently diagnosed with adductor insertional tendinopathy.Case Presentation: We present the case of an Italian 3,000-m steeplechase and long distance runner, Ala Zoghlami (180 cm, 57 kg), with groin pain, diagnosed as…
Adaptació del coeficient de GINI per a la formulació d'un coeficient de desigualtat lingüística
2020
El text adapta el Coeficient de Gini per elaborar un Coeficient de Desigualtat Lingüística (CDL) i aplicar-lo al cas valencià, tenint en compte les Taxes de Competència i les Taxes d?Ús. Es desenvolupen dos models, un basat en corbes parabòliques i un altre basat en corbes exponencials per al cas de disposar d?una parella de dades (x,y). Es calculen els Coeficients de Desigualtat Lingüística en ambdós casos per a les regions sociolingüístiques valencianes. Finalment es compara el resultat amb una corba general per al cas valencià
