Despite the important role of schools in influencing juvenile delinquency, limited research has investigated the contextual effects of schools on delinquency. Using the framework of macro-level strain theory, this study investigates the effects of school-level strain on delinquent behavior among Chinese adolescents. The sample comprises 1411 adolescents from 32 middle schools in Guangzhou, a large city in Southern China. Results from multilevel regression models show that school-aggregated level of strain is positively associated with both self-destructive and other-directed delinquent behaviors, after adjusting for individual strain and other sociodemographic variables. Specifically, school-level anticipated educational goal blockage and negative treatment by teachers are positively associated with self-destructive behavior, whereas school mean level of negative treatment by peers is positively related to other-directed behavior. Although individual-level strain is positively associated with both types of delinquency, it only partially mediates the effect of school-level strain on self-destructive delinquent behavior. This study also investigates whether school-level variables may condition the strain-delinquency relationship. The results show a significant interaction between personal strain and overall delinquent schoolmates on both self- and other-directed delinquent behaviors, indicating that school-level delinquent peers significantly exacerbate the effect of strain on delinquent behaviors. These findings suggest that the effort to reduce juvenile delinquency should target practices to alleviate both individual strain and aggregate strain, and provide more resources and support for students, particularly those in schools with substantial disruptive student behaviors, to legitimately cope with strains.

This research note argues that the “lone wolf” typology should be fundamentally reconsidered. Based on a three-year empirical research project, two key points are made to support this argument. First, the authors found that ties to online and offline radical milieus are critical to lone actors' adoption and maintenance of both the motive and capability to commit acts of terrorism. Second, in terms of pre-attack behaviors, the majority of lone actors are not the stealthy and highly capable terrorists the “lone wolf” moniker alludes to. These findings not only urge a reconsideration of the utility of the lone-wolf concept, they are also particularly relevant for counterterrorism professionals, whose conceptions of this threat may have closed off avenues for detection and interdiction that do, in fact, exist.  相似文献

这项研究探讨香港与上海两地青年的公共政策或社会责任、子孙或家庭责任、个人责任的觉识对其照顾、接纳和承担照顾父母的意愿的效应.研究结果显示:(1)对政府或社会的养老政策责任的觉识愈高者则照顾父母的意愿明显地愈高;然而,对老年人的自立生活具愈高的觉识者,其照顾父母的意愿却愈低;(2)对倡导尊敬老年人的觉识愈高和对老年人的自立生活的觉识愈低者,其接纳照顾父母的意愿愈高;(3)对政府责任的觉识愈高者和对个人责任的觉识愈低者,其承担照顾父母的意愿愈高.文章同时就倡导两地照顾或供养父母的政策启示进行讨论.  相似文献

This paper examines the incentive and the consequences of using discriminatory pricing by a monopolist in a rent-seeking economy. It is shown that, even if all consumer groups' demands have identical elasticities at any given price, the monopolist has an incentive to charge a lower price to high pressure consumer groups so as to alleviate their rent-seeking efforts in challenging its monopolistic power. Furthermore, it is shown that by allowing the firm to price discriminate total welfare may increase, even if all rent-seeking expenditures are completely wasteful.  相似文献

Abstract: The “will of the people’ is considered to be the highest authority in a democracy and said to be the driving force behind public policies. Yet not many past studies have assessed the level of citizen satisfaction with government services and identified ways of improving service delivery. At a municipal level, there is even less emphasis on measuring consumer satisfaction. This study measures citizens' satisfaction with municipal services in a town in Atlantic Canada. A taxonomy of government services based on user experience with the service and heterogeneity of consumer needs was developed and tested. Results indicate that while consumer satisfaction with municipal services is high, it does vary based on the nature of the service. Some action guidelines are suggested at the end of the paper to improve town service delivery. Sommaire: La «volonté du peuple» est considérée comme étant la plus haute autorité dans une démocratice, et l'on dit même que c'est elle qui est à l'origine des politiques publiques. Pourtant, peu d'études ont examiné le niveau de satisfaction du citoyen en ce qui concerne les services gouvernementaux et ont tenté de cerner les moyens permettant d'améliorer ces services. Au niveau municipal, on fait encore moins d'efforts pour mesurer la satisfaction des consommateurs. La présente étude mesure la satisfaction des citoyens à l'égard des services municipaux dans une ville située dans la région Atlantique du Canada. Une taxonomie des services gouvernementaux basée sur l'expérience des utilisateurs et sur l'hétérogénéité des besoins des consommateurs a été mise au point et testée. Les résultats indiquent que, bien que la satisfaction des consommateurs face aux services municipaux soit élevée, elle varie selon la nature de services. À la fin de l'article, on suggère quelques lignes directrices pour améliorer la prestation de services des villes.  相似文献

Fraudulent substitution of a page within a multiple page document such as a will or business contract, the counterfeit manufacture of paper banknotes, and linking ransom or extortion notes have all been the focus of criminal investigations at one time or another. In a recent homicide investigation, document examiners were requested to compare a threatening letter received by a business partner of the deceased with paper samples seized under warrant from a suspect's house. Through a quantitative elemental analysis of the concentrations of nine elements (Na, Mg, Al, Mn, Sr, Y, Ba, La, and Ce) within the questioned and specimen documents, determined by inductively coupled plasma-mass spectrometry (ICP-MS), it was concluded that (i) the paper of the threatening letter originated from a different source to that of the paper seized from the suspect's house and (ii) all six pages of paper seized from the suspect's house originated from the same source. This discrimination of paper is presented as both a statistical t-test analysis (99.9% confidence limit) as well as construction of an elemental fingerprint for individual replicates within the questioned and specimen sample populations. This is the first reported use of the comparison of the elemental composition of document paper, determined by ICP-MS, to assist in a criminal investigation.  相似文献
