The relationship between life satisfaction, risk-taking behaviors, and youth violence 总被引:1,自引:0,他引:1
MacDonald JM Piquero AR Valois RF Zullig KJ 《Journal of interpersonal violence》2005,20(11):1495-1518
This study builds on existing criminological theories and examines the role of life satisfaction and self-control in explaining youth violence. Using data from a stratified cluster sample of 5,414 public high school students who responded to the South Carolina Youth Risk Behavior Survey, the study examines the relationship between adolescents'perceptions of life satisfaction, behavioral risky acts, and self-reported acts of violence. Analyses indicate that higher levels of life satisfaction are associated with lower violence. Participation in work and involvement in health-related risk-taking behaviors pertaining to sex, drugs, and alcohol are also associated with increased violence. The implications of these findings for criminological theory and for school-based violence prevention programs are discussed. 相似文献

A naked man died under peculiar circumstances and the postmortem examination revealed unexpected lesions in the cervical spine. Investigations of the cervical spine (computed tomography, magnetic resonance imaging, and histological examination) showed that a piece of bone was torn of the anterior part of vertebra C6 and that there was fresh bleeding in the surrounding tissue. The cause of death remained unclear but was most likely cardiac arrhythmia initiated by beta-2 agonist inhalation due to an acute asthmatic attack. Data from biomechanical investigation using finite element analysis supported the conclusion that the cervical spine injury was secondary to impact during falling as a consequence of the cardiac arrhythmia. 相似文献

A prospective study of 161 victims of falls from height is reported. The aim was to determine the interest of systematic qualitative and quantitative toxicological analysis in such fatalities. The primary cause of death was suicide (84.5%), followed by accidents (7%) and homicide (1%). In the remaining 7.5%, cause of death was undetermined. In the suicides, there was evidence of psychotropic medicines in 57% of the observations, with a much higher proportion of benzodiazepines and antidepressants in women than in men. Quantitative toxicologic analysis showed overdosing on medication in 16 suicide victims, with toxic levels in 11 of these. Systematic qualitative and quantitative toxicologic analysis made a significant contribution to the diagnosis of suicide by revealing either an unknown psychiatric treatment or a toxic level. 相似文献

Since the end of the Cold War, security studies have broadened to take into account a wide range of non‐military threats ranging from poverty to environmental concerns rather than just national defence. Security scholars, backed by international organizations and a growing number of national governments, have developed the concept of ‘human security’, focusing on the welfare of ordinary people against a broad range of threats. This has aroused vigorous debate. The first part of this article proposes an analytical model of human security. The second part argues that it is important to measure how ordinary people perceive risks, moving beyond state‐centric notions of human security. New evidence is examined that draws upon survey items specially designed to monitor perceptions of human security, included for the first time in the sixth wave of the World Values Survey (WVS), with fieldwork conducted in 2010–12. The third part demonstrates that people distinguish three dimensions – national, community and personal security – and then explores some structural determinants driving these perceptions. The fourth part discusses why perceptions of human security matter, particularly for explaining cultural values and value change around the world. The conclusion argues that the shift from a narrow focus on military security toward the broader concept of human security is a natural response to the changing challenges facing developed societies, in which the cost‐benefit ratio concerning war has become negative and cultural changes have made war less acceptable. In this setting, valid measures of perceptions of human security have become essential, both to understand the determinants of the concept among ordinary people and to analyze their consequences. 相似文献

Many voters are canvassed by British political parties in the months and weeks immediately preceding a general election – but many are not. The parties are selective in whom they make contact with, and where. They focus on those in marginal constituencies who are likely to vote for them – and having identified them early in the process they contact them again, seeking to sustain that support in the seats where the contest overall will be either won or lost. A large panel survey conducted immediately before and after the 2010 general election allows detailed insight into that pattern of canvassing, identifying who the parties contacted, and where, in the six months prior to the election being called, and then who were contacted during the month immediately preceding polling day, and in how many different ways. Each party focused on its own supporters in the marginal constituencies, and in the middle-class neighbourhoods within those constituencies, but whereas the Conservatives, expecting to win the election, campaigned most intensively in the seats they lost by relatively small margins at the previous contest, Labour and the Liberal Democrats fought defensive campaigns in the seats that they won then. Such tactics were successful; the more ways in which respondents were contacted by a party, the more likely they were to vote for it. 相似文献

Gordon Tullock is one of the world’s leading economists. Even more so than Chicago’s Gary Becker, Tullock has extended the rational choice model into areas previously judged to lie outside the realm of economics. This essay identifies Tullock’s contributions to constitutional political economy, public choice, bureaucracy, the law, and bio-economics. The essay focuses attention most especially on Tullock’s pioneering contributions to public choice, including his twenty-year editorship of Public Choice. 相似文献
