Bullying in schools and exposure to domestic violence   总被引:4,自引:0,他引:4  
OBJECTIVES: The study aimed to investigate the relationship between bullying and victimization in school and exposure to interparental violence in a nonclinical sample of Italian youngsters. METHODS: A cross-sectional study was conducted with a sample of 1059 Italian elementary and middle school students. Participants completed a self-report anonymous questionnaire measuring bullying and victimization and exposure to interparental violence. The questionnaire also included measures on parental child abuse and socio-demographic variables. RESULTS: Almost half of all boys and girls reported different types of bullying and victimization in the previous 3 months, with boys more involved than girls in bullying others. Exposure to interparental physical violence and direct bullying were significantly associated especially for girls: girls exposed to father's violence against the mother and those exposed to mother's violence against the father were among the most likely to bully directly others compared with girls who had not been exposed to any interparental violence. Hierarchical multiple regression analyses revealed that bullying and victimization were predicted by exposure to interparental violence, especially mother-to-father violence, over and above age, gender, and child abuse by the father. CONCLUSIONS: Exposure to interparental violence is associated with bullying and victimization in school, even after controlling for direct child abuse. Violence within the family has detrimental effects on the child's behavior; schools, in this regard, can play a fundamental role in early detection of maladjustment.  相似文献

To identify pathways to lower environmental impacts, this research examined the motivation and antecedents of motivation (autonomy, relatedness, competence), of environmentally active people. Previous research suggests that people with more self-determined motivation for pro-environmental behavior (PEB) should carry out more PEBs, and have lower environmental impacts, than people whose motivation is more externally regulated. Path analysis in Sample 1 (N = 261) confirmed that self-determined motivation was positively related to both easy and difficult PEB. The more participants judged that their needs for autonomy and relatedness were met in relation to performing PEB, the more self-determined their motivation. Higher perceived relatedness was also directly related to reporting more engagement in difficult PEB. Perceived competence was not related to self-determined motivation or PEB. The pattern of results was largely supported when re-tested with a sample (N = 320) who completed a ‘carbon footprint’ measure of environmental impact as well as the questionnaire completed by Sample 1. In this sample, autonomy, relatedness, and competence were related to self-determined motivation. The research is the first to our knowledge to examine and find a relationship between higher self-determined motivation and lower self-reported environmental impact. These findings point to new approaches to increasing PEB.  相似文献

This study investigated dopamine receptor genes (DRD2 and DRD4) and maternal sensitivity as predictors of infant respiratory sinus arrhythmia (RSA) and RSA reactivity, purported indices of vagal tone and vagal regulation, in a challenge task at 3, 6, and 12 months in 173 infant-mother dyads. Hierarchical linear modeling (HLM) revealed that at 3 and 6 months, RSA withdrawal in response to maternal separation was greater (suggesting expected physiological regulation) in infants without the DRD2 risk allele than those with the risk allele. At 12 months, infants with the risk allele who were also exposed to maternal sensitivity showed levels of RSA withdrawal comparable to infants who were not at genetic risk. Findings demonstrate the importance of developmental analysis of gene-environment interaction.  相似文献

Visual illusions are objects that are made up of elements that are arranged in such a way as to result in erroneous perception of the objects’ physical properties. Visual illusions are used to study visual perception in humans and nonhuman animals, since they provide insight into the psychological and cognitive processes underlying the perceptual system. In a set of three experiments, we examined whether dogs were able to learn a relational discrimination and to perceive the Müller-Lyer illusion. In Experiment 1, dogs were trained to discriminate line lengths using a two-alternative forced choice procedure on a touchscreen. Upon learning the discrimination, dogs’ generalization to novel exemplars and the threshold of their abilities were tested. In the second experiment, dogs were presented with the Müller-Lyer illusion as test trials, alongside additional test trials that controlled for overall stimulus size. Dogs appeared to perceive the illusion; however, control trials revealed that they were using global size to solve the task. Experiment 3 presented modified stimuli that have been known to enhance perception of the illusion in other species. However, the dogs’ performance remained the same. These findings reveal evidence of relational learning in dogs. However, their failure to perceive the illusion emphasizes the importance of using a full array of control trials when examining these paradigms, and it suggests that visual acuity may play a crucial role in this perceptual phenomenon.  相似文献

This study examines how narrative is used by remote stakeholders to cope with organizational change. Specifically, I focus on the public narratives of community leaders because these narratives often function as a rhetorical resource to attract businesses, receive grants, and retain local residents. Public stories announcing, explaining, and managing the ripple effects of organizational change warrant deeper analysis in order to refine our ability to respond to these effects at a community level. This in-depth case study analysis of one community's efforts to respond to the loss of its largest employer suggests that naming a change event as a crisis, disaster, or opportunity positions actors differently within narratives, creating powerful implications for social action. Specifically, crisis narratives call for punishment of the causal agent and legislation of responsibility; disaster narratives call for assistance to affected communities and legislation of support; and opportunity narratives create an unclear policy mandate and demand transformational leadership to mobilize action.  相似文献

We live in challenging times. The divisions among people related to race, gender, gender identity, religion, and socioeconomic class are becoming more apparent. Past efforts toward social justice and the dismantling of these divisions seem to be losing their momentum and are even negated. As kinesiologists, we each need to commit to standing for social justice with every opportunity we are presented with and most importantly, in our classes. After a review of terms and clarification of ideas related to diversity and social justice, this lecture will present the position that collaboration will provide an effective approach to develop the knowledge, skills, and confidence essential to appropriately address diversity in our professional lives and advocate for social justice. This collaboration should be across disciplines and move us beyond our own research agendas to working with those whose research agendas or areas of expertise are diversity and social justice. Our collective commitment and collaborations will hopefully change the times we are living in to one where each person is respected for who they are, and social justice becomes part of our American fabric.  相似文献

The aim of this meta-study is to provide a critical synthesis of qualitative research on athletic identity in sport psychology. A total of 108 empirical studies were identified, including 63 quantitative studies, 40 qualitative studies, and five mixed methods studies. Qualitative and mixed methods studies were reviewed with the meta-study method, which involves a meta-analysis in terms of theoretical perspectives, methodologies, and findings. In our discussion we focus on evaluating and critiquing the current status of qualitative research on athletic identity and outlining recommendations for improving methodological rigor. It is concluded that both quantitative and qualitative studies need to be more explicit about their philosophical underpinnings and better grounded in psychological identity theory.  相似文献

ABSTRACT

This study aimed to examine the scoring mode (line goal, double goal or central goal) and age-related effects on the defensive performance of youth soccer players during 4v4 small-sided games (SSGs). Altogether, 16 male players from 2 age groups (U13, n = 8, mean age: 12.61 ± 0.65 years; U15, n = 8, 14.86 ± 0.47 years) were selected as participants. In six independent sessions, participants performed the three SSGs each during 10-min periods. Teams’ defensive performance was analysed at every instant ball possession was regained through the variables: ball-recovery type, ball-recovery sector, configuration of play and defence state. Multinomial logistic regression analysis used in this study revealed the following significant main effects of scoring mode and age: (1) line goal (vs. central goal) increased the odds of regaining possession through tackle and in the defensive midfield sector, and decreased the odds of successful interceptions; (2) double goal (vs. central goal) decreased the odds of regaining possession through turnover won and with elongated playing shapes; (3) the probability of regaining possession through interception significantly decreased with age. Moreover, as youth players move forward in age groups, teams tend to structurally evolve from elongated playing shapes to flattened shapes and, at a behavioural level, from defending in depth to more risky flattened configurations. Overall, by manipulating the scoring mode in SSGs, coaches can promote functional and coadaptive behaviours between teams not only in terms of configurations of play, but also on the pitch locations that teams explore to regain possession.  相似文献

The relationship between study success and the nature of 550 first-year law students’ study processes was investigated using a modified version of the Approaches to Learning and Studying Inventory. The students were classified into four study profiles according to their approaches to learning, indicating the nature of their study processes. In addition, the students were divided into six study success groups on the basis of their earned study credits and grade point average. The results showed that both approaches to learning and study success in the first study year predicted graduation time and the completion of the degree. Thus, it is important that faculties actively use measures, such as the inventory used in the present study, to promote first-year students’ awareness of their study practices and support the progress of their studies. Individual students need tailored guidance in transitioning to university studies and identifying the demands of the study programme.  相似文献
