Panel data in the National Longitudinal Survey of Youth (NLSY97) provide an excellent opportunity to examine the relationship between Hispanic immigration, assimilation, and retail theft. This study examines the relationship between length of time Hispanic youth have spent in America, with the probability of stealing from a store. After controlling for traditional predictors of crime that are correlated with adolescence and immigrant status, random effects logistic regression models indicate that immigrants are less likely to steal than non-immigrants. However, calculating the marginal effects of time spent in the United States reveals that their probability increases with assimilation. Supplementary analyses specify that Hispanic youth who enter the United States within their first 5 years of age will have higher odds of engaging in retail theft. Supportive parenting and a structured home environment is a consistent protective factor in the models. Policies targeting pro-family and social identification are likely to benefit immigrant youth as they acculturate to America. 相似文献

Life satisfaction is quite heterogeneously distributed across countries of the enlarged European Union. Previous research has shown how living conditions within individual countries, such as access to material and emotional resources, are important for personal well-being, but it has been less successful in explaining differences between countries. This article investigates whether it matters in which political and economic circumstances people live, as well as whether their particular perception of the quality of their societal environment plays a role. People are well aware that the institutional and cultural settings in which their lives are embedded create opportunities and limitations: within individual countries, perceptions of society influence life satisfaction outcomes irrespective of access to resources. However, their importance for well-being differs across Europe: perceptions of societies are highly decisive in countries that provide only a minimum of social security and in which the reliability of political institutions is poor. In rich and stable countries, the impact is weaker and private social support becomes more important. In addition to these country-specific weights of life satisfaction determinants, life satisfaction variations between countries can be explained to a large extent by taking into consideration the economic performance, the social security level, and the political culture in a country—all in all, general conditions that enable people to live a respectable life. 相似文献

The good government models of the 1990s realized a focus that included reinventing, reengineer-ing, rethinking, quality, empowerment, and devolution of the organization. These organizational reform ideologies sought to increase involvement, improve productivity, manage performance, and drive results. One essential key that has been disregarded in these government models is the involvement of community in the decision-making process. This paper points to the importance of involving and empowering citizens in the decision-making process, particularly in regard to community justice based on the notion of restorative justice system. Community justice, a modern day reform movement with international proportions, is based on the principles of empowering community, repairing harm caused by a crime or disturbance, and reducing risk to the community. 相似文献

En route to the top. Requirements on candidates for top positionsThe assessment of candidates for positions as managing director or as an executive committee member by means of management diagnostics has been frowned upon by German companies for a long time. There has, however, been a clear change of opinion regarding this matter in the meantime. The authors have developed a model of requirements to assess the competencies and potential critical for success. Six areas of responsibility are differentiated between thereby: “Ability to cope with complexity” and “development of decidedness”, “Will to create” and “establishment of structures”, “Establishment of bonds” and “ability of self-management”, and are divided into three levels: the personal level, the co-operative level and the level of corporate culture respectively. 相似文献

We study the extremal parameter N(n,m,H) which is the largest number of copies of a hypergraph H that can be formed of at most n vertices and m edges. Generalizing previous work of Alon (Isr. J. Math. 38:116–130, 1981), Friedgut and Kahn (Isr. J. Math. 105:251–256, 1998) and Janson, Oleszkiewicz and the third author (Isr. J. Math. 142:61–92, 2004), we obtain an asymptotic formula for N(n,m,H) which is strongly related to the solution α
q
(H) of a linear programming problem, called here the fractional q-independence number of H. We observe that α
q
(H) is a piecewise linear function of q and determine it explicitly for some ranges of q and some classes of H. As an application, we derive exponential bounds on the upper tail of the distribution of the number of copies of H in a random hypergraph. 相似文献

In this paper we explore the use of disclosure as a regulatory tool, using as an illustration the current UK requirements regarding the disclosure of information about internal control. After discussing the broad concept of regulation by disclosure, we trace the evolution of concepts of internal control and its reporting, describing the background to the Turnbull guidance for directors on internal control reporting, the basis of current UK requirements. We then examine recent examples of internal control disclosures, identifying the range of ways in which they address the disclosure requirements and considering the possible impact of the disclosure requirements on corporate behaviour and on the audiences for disclosure. We conclude with some reflections on the disclosure life cycle. The paper contributes to the literature on disclosure by specifically considering the role of disclosure as a regulatory tool and by examining the nature of specific disclosures in an area of continuing interest, that of internal control. 相似文献
