Background: Peer victimization is ubiquitous across schools and cultures, and has the potential for long-lasting effects on the well-being of victims. To date, research has focused on the consequences of peer victimization during childhood but neglected adolescence. Peer relationships and approval become increasingly important during adolescence; thus, peer victimization at this age may have a damaging psychological impact. Methods: Participants were 5030 adolescents aged 11–16 recruited from secondary schools in the UK. Self-report measures of victimization and symptoms of anxiety and depression were administered on three occasions over a 12-month period. Latent growth models examined concurrent and prospective victimization-related elevations in anxiety and depression symptoms above individual-specific growth trajectories. Results: Peer victimization was associated with a concurrent elevation of 0.64 and 0.56 standard deviations in depression and anxiety scores, respectively. There was an independent delayed effect, with additional elevations in depression and anxiety (0.28 and 0.25 standard deviations) six months later. These concurrent and prospective associations were independent of expected symptom trajectories informed by individual risk factors. Conclusions: Adolescent peer victimization was associated with immediate and delayed elevations in anxiety and depression. Early intervention aimed at identifying and supporting victimized adolescents may prevent the development of these disorders. 相似文献

Between 1980 and 2010 there were 1 million homicides in Brazil. Dramatic increases in homicide rates followed rises in inequality, more young men in the population, greater availability of firearms, and increased drug use. Nevertheless, disarmament legislation may have helped reduce homicide rates in recent years. Despite its very high rate of lethal violence, Brazil appears to have similar levels of general criminal victimization as several other Latin American and North American countries. Brazil has lower rates of drug use compared to other countries such as the United States, but the prevalence of youth drug use in Brazil has increased substantially in recent years. Since 1990, the growth of the Brazilian prison population has been enormous, resulting in the fourth largest prison population in the world. Through a systematic review of the literature, we identified 10 studies assessing the prevalence of self-reported offending in Brazil and 9 studies examining risk factors. Levels of self-reported offending seem quite high among school students in Brazil. Individual and family-level risk factors identified in Brazil are very similar to those found in high-income countries. 相似文献

This paper analyzes the levels of job satisfaction reported by older workers (aged 50–64) with and without disability by using an aggregating approach in which job satisfaction is seen as a combination of various job satisfaction domains (physical effort, time pressure, level of freedom, capability to develop new skills, support in the workplace, recognition of the work, salary, promotion prospect and job security). Using the Survey of Health, Ageing and Retirement in Europe, we estimate a two-layer model based on the interrelation between the different domains of job satisfaction and wherein the individual’s overall job satisfaction depends on each of these domains. The results show that the levels of satisfaction with the recognition of the work, support in difficult situations and physical effort have a significant effect on the overall job satisfaction reported by limited disabled workers. For this group, the trade-offs between the domains recognition with work and support and satisfaction with salary are especially high. These findings can help organizations, managers and policy makers to design or modify current jobs to make them more attractive in terms of satisfaction for limited disabled older workers. 相似文献

ResumenEsta investigación ha tenido como objetivo comparar la amplitud de aprehensión de dos grupos de pacientes esquizofrénicos (paranoide y no-paranoide) y la de un grupo de sujetos normales. Las variables independientes han sido la duración de la exposición y el número de items. Los resultados sugieren que los esquizofrénicos procesan la información visual menos eficientemente que los normales. 相似文献

AbstractThe relationship between music training and cognitive performance has been much explored over the last decades. A variety of evidence shows a different neurological and cognitive processing in the population who have undergone instrumental music training compared to people who have not. A review of the literature shows the many advantages in cognitive skills musicians have gained from musical training, such as benefits to their executive functions and other aspects of cognition, in children as well as adults and the elderly. This study investigates in greater depth certain cognitive aspects associated with musical training in the adult population. Specifically, it explores its relationship with inhibition, working memory (verbal and visual-spatial), flexibility, processing speed, fluid intelligence and divided attention. Our results suggest that there is indeed a relationship between musical training and improvements in cognitive performance, both in executive functions and in other areas of cognition. 相似文献

Goldfish (Carassius auratus) were trained in different place-finding tasks as a means of analyzing their ability to encode the geometric and the featural properties of the environment. Results showed that goldfish could encode and use both geometric and featural information to navigate. Goldfish trained in a maplike, or relational, procedure encoded both types of information in a single representation. In contrast, fish trained in a directly cued procedure developed 2 independent and competing strategies. These results suggest that the geometric properties of the spatial arrangement and discrete landmarks are sensitive to encoding in a maplike or relational system, whereas different sources of spatial information are encoded in a single and flexible representation of the environment. 相似文献
