Secure and sustainable but not as prominent among the ambivalent: Attachment style and proenvironmental consumption
2021
Abstract Human activity has degraded the environment and contributed to numerous public health hazards. Thus, the United Nations recently made an urgent call to develop sustainable consumption practices. Although existing literature has acknowledged attachment style as a potential predictor of certain consumption responses, its influence on proenvironmental consumption has not yet been examined. We conducted a large-sampled study (N = 1397) on this topic and found securely attached individuals to report significantly higher scores on a scale measuring proenvironmental consumption compared to people with anxious/ambivalent and avoidant attachment styles, respectively. The latter two groups d…
COLLABORATIVE ECONOMY AS AN INDICATION OF SUSTAINABLE CONSUMPTION IN RESULTS OF EXAMINED PEOPLE
2017
Sustainable consumption takes inspiration from the newest trends in economics which is a collaborative economy. This type of economy changes the model of organization and distribution based on sharing, using and creating together. The basic aim of this study is pointing out a purpose of a collaborating economy in the accomplishment of sustained consumption rules and in a conscious and self-motivated limit of personal consumption to the purpose of co-sharing. This task is going to be achieved with empirical verification of consumers behavior based on answers to a questionnaire. Research has confirmed the suggested hypothesis. People want to attend in collaborative consumption, which is posit…
Contextual resources in meaning negotiations of a student pair in a web-based history project
2007
Abstract This study examines how one student pair working face-to-face at a computer and engaged in a web-based discussion environment negotiated meanings for their activity and what contextual resources they used in this negotiation process. The aim was also to study how the students themselves interpreted the learning activity. The subjects were two secondary school students (aged 15) participating in a web-based history project. Data was collected by various means in order to validate the findings. Linell's [(1998). Approaching dialogue. Talk, interaction and contexts in dialogical perspectives . Amsterdam: John Benjamins Publishing Co.] notion of contextual resources was used as an anal…
Exception-Tolerant Hierarchical Knowledge Bases for Forward Model Learning
2021
This article provides an overview of the recently proposed forward model approximation framework for learning games of the general video game artificial intelligence (GVGAI) framework. In contrast to other general game-playing algorithms, the proposed agent model does not need a full description of the game but can learn the game's rules by observing game state transitions. Based on hierarchical knowledge bases, the forward model can be learned and revised during game-play, improving the accuracy of the agent's state predictions over time. This allows the application of simulation-based search algorithms and belief revision techniques to previously unknown settings. We show that the propose…
Concepções pessoais de inteligência e auto-estima: que diferenças entre estudantes portuguese e italianos?
2004
Neste artigo apresentam-se alguns dos resultados de um estudo intercultural sobre as concepções pessoais de inteligência e a auto-estima global, comparando alunos de dois níveis de ensino (secundário e superior) de Portugal e de Itália. A amostra total compreende 1540 alunos, 811 italianos e 729 portugueses, de ambos os sexos e de diferentes níveis sócio-económicos, frequentando os 10.º e o 12.º anos do ensino secundário e o 1.º ano de vários cursos universitários em ambos os países. Os instrumentos utilizados foram a Escala de Con- 763 cepções Pessoais de Inteligência (Faria, 2003), com 26 itens, e a Escala de Auto-Estima Global (Rosenberg, 1965), com 10 itens, traduzidas e adaptadas para …
UNIVERSITY STUDENTS’ GROWTH GOALS, OPPORTUNITIES FOR GOAL FULFILLMENT, AND PERCEIVED UNIVERSITY AND MESOSYSTEM SUPPORT
2021
This study assessed the relationship between students’ growth goals and perceived opportunities to achieve these goals in Latvia and the perceived support from the university and the mesosystem. Socialization models emphasize that the setting of personal goals occurs in continuous interaction with the sociocultural context, which includes perceived opportunities to achieve these goals and the interpersonal environment. Both – perceived support from close people (mesosystems) and perceived support from the university – are significant for students. The study involved 432 university students between 18 and 49. We have assessed the extent to which students’ goals regarding education, work, and…
The Playing Brain. The Impact of Video Games on Cognition and Behavior in Pediatric Age at the Time of Lockdown: A Systematic Review
2021
A growing number of children and adolescents play video games (VGs) for long amounts of time. The current outbreak of the Coronavirus pandemic has significantly reduced outdoor activities and direct interpersonal relationships. Therefore, a higher use of VGs can become the response to stress and fear of illness. VGs and their practical, academic, vocational and educational implications have become an issue of increasing interest for scholars, parents, teachers, pediatricians and youth public policy makers. The current systematic review aims to identify, in recent literature, the most relevant problems of the complex issue of playing VGs in children and adolescents in order to provide sugges…
The role of teachers’ controlling behaviour in physical education on adolescents’ health-related quality of life: test of a conditional process model*
2019
AbstractStudents’ health-related quality of life (HRQoL) may depend on the extent to which the school environment fostered by their teacher is perceived as autonomy-supportive. We tested a conditio...
How Physical Education Teachers’ Interpersonal Behaviour is Related to Students’ Health-Related Quality of Life
2019
Grounded in self-determination theory (SDT), this cross-sectional study tested relations of students’ perceptions of autonomy-supportive and controlling behaviour from teachers in physical education with students’ health-related quality of life (HRQoL), and the potential role of students’ perceived need satisfaction and need frustration as a mediator of these relationships. School students (N = 1031) completed self-report measures of perceived autonomy support, perceived teachers’ controlling behaviour, students’ need satisfaction and need frustration, and HRQoL. Results indicated that students’ perceptions of autonomy support from teachers was positively associated with HRQoL through need …
Heat transfer simulation in a vertical Bridgman CdTe growth configuration
1999
Modelling and numerical simulation of crystal growth processes have been shown to be powerful tools in order to understand the physical effects of different parameters on the growth conditions. In this study a finite difference/control volume technique for the study of heat transfer has been employed. This model takes into account the whole system: furnace temperature profile, air gap between furnace walls and ampoule, ampoule geometry, crucible coating if any, solid and liquid CdTe thermal properties, conduction, convection and radiation of heat and phase change. We have used the commercial code FLUENT for the numerical resolution that can be running on a personal computer. Results show th…
