The limited literature on the topic speculates that the rate of ADHD would be higher among incarcerated youth than found in the general population. However, to our knowledge no such published figures exist for juveniles in the United States. This study investigates the likelihood of ADHD diagnosis among 453 incarcerated youth and compares and contrasts a variety of demographic, social, educational, psychological, and criminal characteristics to the general literature on ADHD. Both similarities and differences are reported. This project was supported by Grant #99-RT-VX-K020 awarded by the National Institute of Justice. Points of view in this document are those of the author and do not necessarily represent the official position or policies of the U.S. Department of Justice. An early version of the paper was presented at the annual meeting of the Academy of Criminal Justice Science in Chicago, Illinois.  相似文献

Political scientists lack domain‐specific measures for the purpose of measuring the sophistication of political communication. We systematically review the shortcomings of existing approaches, before developing a new and better method along with software tools to apply it. We use crowdsourcing to perform thousands of pairwise comparisons of text snippets and incorporate these results into a statistical model of sophistication. This includes previously excluded features such as parts of speech and a measure of word rarity derived from dynamic term frequencies in the Google Books data set. Our technique not only shows which features are appropriate to the political domain and how, but also provides a measure easily applied and rescaled to political texts in a way that facilitates probabilistic comparisons. We reanalyze the State of the Union corpus to demonstrate how conclusions differ when using our improved approach, including the ability to compare complexity as a function of covariates.  相似文献

The influence of childhood contexts on adult blood pressure is an important yet understudied topic. Using a developmental perspective, this study examines the association between neighborhood socioeconomic disadvantage in early childhood (0–5?yrs), middle childhood (6–12?yrs) and adolescence (13–18?yrs) on subsequent blood pressure in young adulthood. Data were from 263 college students (52% Black; Mage?=?19.21 years) and neighborhood socioeconomic disadvantage was measured using a tract-level Area Deprivation Index. Neighborhood disadvantage in early childhood was significantly associated with diastolic blood pressure and explained 22% of the race difference between Black and White adults. The findings are consistent with the notion that early childhood may be a sensitive period for the effects of neighborhood disadvantage on blood pressure.

The private investigation industry in the United Kingdom has been challenged by dubious work practices arising from the activities of a number of private investigators undertaking work for The News of the World. The allegations of private investigators acting as a conduit for improper behaviour are not new; in Australia this assessment was borne out in the 1992 New South Wales Independent Commission Against Corruption (ICAC) inquiry which found that investigators acted as the go-betweens in a ‘massive illicit trade’ in confidential information (Independent Commission Against Corruption (ICAC), 1992). The last study on private investigator's in Australia was undertaken by Prenzler (2001). In terms of public awareness the image of the private investigator remains a person of dubious character spying on domestic couples. Since the last study the private investigation industry has undergone significant changes in terms of licensing training, regulation and investigative services. These developments have not received much attention in the public media. This lack of media attention is somewhat surprising as developments pose challenges to the justice system.  相似文献

Are sectorally dependent states destined to regime instability as a result of chornic fiscal crisis? Literature emphasizing the importance of a country’s sectoral endowment suggests that oil exporters in particular should exhibit similar policy stagnation and regime decay as a result of fiscal crisis. The cases of Kuwait, Qatar, and Bahrain in the 1980s and 1990s demonstrate that fiscal crisis outcomes are not uniform. This article develops the critique that structuralist assumptions about what drives business-state relations during crisis are flawed. Abstract logics typing exogenous price sifts to the character of business-state interaction neglect the historical and instituional grounding of those relations. It is variation in the historical and institutional crafting of business-state relations that best explains how these relations shape reform under crisis and how regime stability is affected.  相似文献
