Alianzas antiembalse y luchas hidroepistemológicas. Los retos de la gestión colectiva del agua en el Río Grande, Málaga, España

2018

En este artículo analizamos las luchas epistemológicas y retos que ha tenido el movimiento social en la subcuenca del río Grande frente a los diversos proyectos modernizadores que intentan transferir el agua rural hacia la ciudad de Málaga. El primero asociado a la construcción de un gran embalse y el segundo con la modernización de los sistemas de riego tradicionales. Concluimos que el reto está en desenmascarar el régimen de verdad que respalda los proyectos de modernidad hidráulica, reivindicar los derechos de uso y control colectivos del agua y así generar procesos de apropiación comunitaria para la defensa del río como un bien socio-ambiental, económico-cultural y político-epistemológi…

Roczna wydajność instalacji PV zamontowanej na dachu budynku dydaktycznego Uniwersytetu Opolskiego

2018

Celem badań była analiza i ocena sprawności pracy instalacji fotowoltaicznej zamontowanej na dachu budynku dydaktycznego Uniwersytetu Opolskiego mieszczącego się przy ul. Kominka 6 w Opolu. Zakres pracy obejmował ocenę: energetyczną - uzysku energetycznego (ilość wyprodukowanego prądu a położenie geograficzne paneli fotowoltaicznych) i ekologiczną - redukcja emisji szkodliwych substancji niewyemitowanych do aerozolu atmosferycznego z powodu produkcji prądu przez instalację PV, a niedostarczonej przez elektrownię opalaną węglem. Badania wykazały dobry wynik uzysku energetycznego w ciągu roku - 5,30 MWh energii z tego systemu oraz znaczną redukcję emisji CO2 do atmosfery - 4,27 Mg/rok, co pot…

A New Academic Quality at Work Tool (AQ@workT) to Assess the Quality of Life at Work in the Italian Academic Context

2022

Refereed/Peer-reviewed The present study provides evidence for a valid and reliable tool, the Academic Quality at Work Tool (AQ@workT), to investigate the quality of life at work in academics within the Italian university sector. The AQ@workT was developed by the QoL@Work research team, namely a group of expert academics in the field of work and organizational psychology affiliated with the Italian Association of Psychologists. The tool is grounded in the job demands-resources model and its psychometric properties were assessed in three studies comprising a wide sample of lecturers, researchers, and professors: a pilot study (N = 120), a calibration study (N = 1084), and a validation study …

The roles of achievement-related behaviours and parental beliefs in children´s mathematical performance

2003

This study aimed to investigate the developmental dynamics between children's mathematical performance, the task-focused versus task-avoidant behaviours they show in the classroom, and their parents' beliefs concerning their school competence. The mathematical performance of 111 six- to seven-year-old children was tested, and their task-focused versus task-avoidant behaviours were rated by their teachers four times during their first school year. Parents filled in questionnaires measuring their skill-specific and general beliefs about their children's school competencies at the beginning and at the end of the school year. The results showed that parents' beliefs in their children's general …

Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…

2021

Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…

Student participation in peer interaction : use of material resources as a key consideration in an open-ended problem-solving mathematics task

2021

This study explores how students deal with material resources in their peer interaction when working in pairs in an open-ended problem-solving task. The productive use of material resources can be expected to support successful peer work. However, research into social phenomena in peer interaction is needed in order to identify and describe productive and less productive forms of dealing with material resources as students participate in open-ended problem-solving tasks. Consequently, this explorative study responds to this research need. Based on multimodal data, including video recordings, transcribed talk and the written contributions from four pairs of Year 7 students aged 12-13 years, …

Decoupled control scheme of grid-connected split-source inverters

2017

Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…

Interaction between students and class teachers in vocational education and training: ‘Safety distance is needed’

2020

Interaction between students and teachers is fundamental and has therefore been widely studied in education. However, there have been few studies on intensive spe-cial support being provided to vocational education and training (VET) students. Firstly, the focus of this article is on students’ perceptions of interactions with their class teachers. Students (aged 17–34 years) from four Finnish vocational institutions providing intensive special support were interviewed. According to the findings, the demands students placed on their class teachers and for interactions with them were modest and their perceptions of both were favourable. Interactions seemed to be study-orientated and class tea…

The Emotion Detectives Game: Supporting the Social-emotional Competence of Young Children

2017

The potential of digital games to enhance learning in different areas of child development has drawn increasing interest amid growing concern about children’s emotional well-being, social-emotional difficulties, and problem behaviors alongside diminishing economic resources for intervention and habilitation. However, digital games designed to promote social-emotional competence are surprisingly scarce. In this chapter, we explore children’s use of the digital game Emotion Detectives (ED), designed to promote children’s acquisition of emotional knowledge skills (e.g., recognizing, appreciating, and understanding emotions and their expressions), prosocial behaviors (e.g., helping, sharing, co…
