Is the human species hard-wired for violence? It is often assumed to be the case, accompanied by the assumption that external controls are needed to mitigate aggressive tendencies. But there are several empirically based counterarguments to this pessimist view, many of which underscore that the pessimistic view reflects shifted baselines—from child-raising practices, to what is considered normal human development and nature. We examine briefly views from ethological, historical, developmental, anthropological, and biological research.  相似文献

This paper follows earlier research (Rowe et al., 1992) in evaluating the basis of family influences on adolescent delinquent behavior. Delinquency is measured in a number of different ways to account for important theoretical distinctions that exist in the delinquency literature. We use recently identified kinship structure in a large national data set—the National Longitudinal Survey of Youth—to estimate genetic and shared environmental influences on self-reported delinquency scores. Our analytic model is based on DF analysis, a regression procedure used to estimate parameters reflecting genetic and environmental influence. Results suggest a consistent and moderate genetic basis to sibling similarity in delinquency and little evidence of a shared environmental basis. A large amount of variance is attributable to nonshared influences and/or measurement error. Our findings suggest that the search for environmental influences on adolescent delinquency should focus on those that are not shared by siblings.  相似文献

Much research has been conducted into aspects of the police workplace that contribute to stress for individual officers. The current paper examines the influence of worksplace and job characteristics on both officers' stress and their job satisfaction. Police officers recruited from two divisions of an Australian state police service (n=749) were surveyed. Results show that there was a positive relationship between organizational support and job satisfaction and a negative relationship between organizational support and job stress. Difficulty in dealing with organizational change led to lower job satisfaction and higher levels of job stress. Working long hours led to increased job stress but it did not lead to lower job satisfaction. In contrast, shiftwork led to lowered job satisfaction but it did not lead to job stress. Of particular interest in this study was the finding that the job content factor of dealing with dangerous and unpredictable duties was not predictive of job stress but in fact led to higher job satisfaction.

Several studies have indicated that an early onset of delinquent and problem behaviors is associated with a greater risk of subsequent behavioral and mental health problems. This study builds on that literature by examining histories of behavior problems in relation to indicators of thriving and precocious behavior during late adolescence. Using longitudinal data from 289 high-risk adolescents, participants were classified according to their problem behavior histories at ages 15 and 19. Findings indicated that although some adolescents experienced decline over time in their overt behavior problems, those youth showed fewer indicators of thriving when compared to adolescents with no history of behavior problems. Youth with an earlier onset of behavior problems also evinced an increased risk for precocious behavior. Gender differences and implications for prevention through youth development programming are discussed.

Hopeful expectations for the future have been shown to play an important role in the positive development of youth, including youth contributions to society. Although theory and some research suggest that familial socialization may influence future-oriented cognitions, little work has focused on the possible interrelation of parent–child relationships and the development of hope, particularly during adolescence. Accordingly, the first goal of this study was to identify developmental profiles of youth with respect to hopeful future expectations (HFE) and parental trust across adolescence. Next, we explored whether these developmental trajectories were related to youth Contribution, indexed by community leadership, service, and helping attitudes and behaviors. We used growth mixture modeling to simultaneously examine trajectories of adolescents’ perceived connections with parents (indexed by parent trust) and HFE among 1,432 participants (59 % female) from Waves 3 through 6 (Grades 7 through 10) of the 4-H Study of Positive Youth Development. A four-profile model provided the best fit to the data, with the following profiles: Moderate HFE/U-shaped Trust; Moderate HFE/Increasing Trust; Both Decreasing; and Both High Stable profiles. We then explored whether hope-trust profiles were related to youth Contribution in Wave 7. Contrary to hypotheses, results indicated that the profile reflecting the greatest discrepancy in HFE and trust across early to middle adolescence (i.e., Moderate Hope/U-shaped Trust) was associated with the highest mean Contribution scores. The implications of the findings for future theory and research are discussed.  相似文献

The desired outcome for children in foster care is to be reunited with their parents or to be permanently placed in a stable home. Federal and state legislation directs increased efforts by the social welfare and judicial systems in the United States to act in the best interests of the child and to identify and reduce barriers to permanency. Records from two county dependency courts in Florida were examined and caregivers surveyed to identify issues that prevented them from adopting the child in their care, and to identify services that would have enhanced the likelihood of adoption. The findings and their implications suggest that more integration of the two systems and support for concrete assistance to caregivers are paramount to facilitating adoption of children in foster care.  相似文献
