This article identifies the arrest trajectories of youth from ages 12 through 24 years old and tests hypotheses derived from Moffitt’s developmental taxonomic theory of crime concerning the impact of various emotional disturbances on the specific trajectories of the youth involved. The study uses exclusively administrative data sets and includes a gender and racially diverse sample of 10,360 youth (30.7 % females) who were arrested at least once between ages 12 and 24 in the early 2000s. Latent class growth analysis was employed in order to identify distinct arrest trajectories of youth in the sample. Multinomial logistic regression was used to identify diagnostic and other characteristics associated with membership in the specific trajectories predicted by Moffitt’s theory. Five trajectory classes were identified, 3 of which were consistent with taxonomic theory including high and classic adolescence limited trajectory classes and a “snared adolescence limited class” described more recently by Moffitt. The distribution of youth among the 5 classes was very different for those with and without emotional disturbances. Youth with emotional disturbances in their late adolescent years were more likely to fall into the high arrest trajectory class and much less likely to fall into the low arrest trajectory class. Compared to youth without an emotional disturbance, youth with psychotic disorders were more than twice as likely to fall into the high as into the low arrest trajectory class. Youth with disruptive behavior disorders were more than twice as likely to fall into the high and intermediate classes as into the low trajectory class. Anxiety and depressive disorders were not associated with significantly greater likelihood of falling into any one of the trajectory classes. Youth in the snared adolescence limited class were more likely than those in the classic adolescence limited class to be male, black versus white and in the foster care enrollment category lending some support to Moffitt’s conceptualization of this class as an adolescence limited class composed of youth who are snared by involvement in the criminal justice and or social services systems. Implications of these results for public policy and the study of adolescence are discussed. 相似文献

This paper examines whether foreign direct investment (FDI) influences confidence in commercial contracts in developing countries. While the research on how host countries’ policy environments encourage FDI inflows has flourished, scholars have paid less attention to how the policy environment and local actors’ beliefs might, in turn, be affected by FDI. This is surprising because multinational enterprises are well‐recognized political and economic actors across the world. We expect that their increasing economic salience will influence the policy environments in which they function. By employing an innovative measure of property rights protection – contract‐intensive money – we examine how foreign direct investment influences host countries’ contract‐intensive money ratio in a large panel time series of both developed and developing countries from 1980 to 2002. Our analysis suggests that higher levels of FDI inflows are associated with greater confidence in commercial contracts and, by extension, the protection of property rights in developing countries. 相似文献

The disintegration of the Soviet Union had profound economic and social effects on many of the newly independent transition economies. Nowhere was this more so than in the fisheries sector – with one of the biggest production shortfalls occurring in Kyrgyzstan, following the collapse of lake capture and pond-culture production. In 2005, aggregate landings were just 48 tonnes – barely 3 per cent of the catch level recorded in 1989. This article has two objectives. First it analyses the extent to which the dissolution of the Soviet Union can explain the collapse of the fisheries sector in Kyrgyzstan. Second, in the light of these findings, it considers what practical steps, if any, might be taken to revitalize the sector. 相似文献

This article contains an examination of the way in which the largely British model of professional comprehensive housing management became important in Hong Kong. It shows how a comparatively small number of pioneers, mainly women who were followers of the principles of Octavia Hill, a philanthropic social reformer who developed her ideas in 19th century London, had a considerable influence in the very different environment of Hong Kong. An examination of the comparatively small amount of literature on the housing management profession is followed by a detailed analysis of the way in which the housing management profession has developed in Hong Kong. A review of the origin of public housing programmes in Hong Kong highlights the influence which housing professionals had when the housing administration was radically restructured at the time of the formation of the Hong Kong Housing Authority in the early 1970s. 相似文献

This paper examines Scottish licensing law, in particular the granting of licenses to supply alcoholic liquor. Any application for a license must be granted unless one or more of four conditions are fulfilled. One of these, that the award would lead to overprovision, is the central concern of this study. The paper does not investigate why the consumption and distribution of alcohol are regulated nor why regulatory control takes the form it does. 1 The starting point is rather that regulation exists and takes a particular form. Attention is focused on the operation of this regulatory control and with how it might be improved.In the next section, some of the key features of the licensing law and its appeals are reviewed, establishing the importance of evidence of the presence or otherwise of overprovision. Section II discusses the use of density of licensed premises as a measure of provision, indicates the problems, and argues that a measure might be refined and validated by entering it in an equation explaining the retail price of alcoholic beverages. Section III examines empirically the relationship between price and licensing density. 相似文献

What follows is a reply to a number of points raised by Nicos Mouzelis in his review of my book, From Modernisation to Modes of Production: A Critique of the Sociologies of Development and Underdevelopment (Macmillan 1979, £4.95 paper) in The Journal of Peasant Studies, Volume 7, No. 3, April 1980. I focus on Mouzelis’ arguments that my framework for analysing Third World societies is ideological and reductionist. I try to show how the analysis put forward in my book can be used to analyse what for me is the central problem of ‘development ‘ ‐ namely the relations between the restricted and uneven capitalist development characteristic of Third World societies, their class structures, forms of state and development strategy. I also examine the relevance of Mouzelis's alternative ‐ of inter‐relating structuralist and action perspectives ‐ and suggest that the framework put forward in my work can deal more adequately with the issues raised by Mouzelis in his review. I agree with Mouzelis that the most fruitful debates in the Sociology of Development currently centre on the relevance of the Marxist approach, and view my comments here as part of this wide‐ranging, continuing debate, of which my work forms a part. 相似文献
