The procedure used in this laboratory for removing and identifying contamination of hair specimens with drugs is demonstrated by its application to hair contaminated by various experimental models. The models include soaking; coating with drug followed by sweat conditions for 6 h; and soaking in a very high concentration of cocaine followed by storage and multiple shampoo treatments. A multi-part wash procedure along with a wash criterion is applied to all samples containing drug above the cutoff. The failure of the wash criterion is a signal that the sample may be positive due to contamination rather than use, and in the absence of other over-riding evidence, the sample would be considered to be negative for drug use. This Wash Criterion has also been tested with hair from subjects demonstrated to be drug users by one or more drug-positive urines; in these studies, all hair samples from demonstrated users passed the Wash Criterion test. 相似文献

Definitions of sexual sadism in ICD-10 and DSM-IV will be presented as well as the historical routes of the concept. Today studies on differently selected clinical samples reveal a different distribution of sexual sadism versus masochism with masochism prevailing in general especially outpatient psychiatric facilities, and sadism prevailing in forensic settings, thus corroborating the concept of two separated diagnoses sadism versus masochism. In forensic settings the diagnosis of a sadistic character disorder (sadistic personality disorder [SPD] according DSM-III-R) is found to a much higher degree than in other clinical samples (50-fold). Our own follow-up study on a forensic sample implies that sadism as a paraphilia is of relevance for relapse-rates of sex-offenders. Symptoms of SPD can be combined with sexual sadism, or occur independently. This may corroborate arguments in favor of a dimensional concept of sexual sadism. Symptoms of SPD may then be a sign of generalization of sadistic traits at least in some cases. A concept of two factors contributing to sadistic pleasure is suggested, one taking the aspect of bodily gratification by sexual-aggressive stimuli as decisive, and the other taking inner representation of hostile objects into consideration (stressing the antisocial-anger-rage aspect). 相似文献

The power to impound allows the president to cancel or postpone the spending of appropriated funds. Over the years Congress has struggled with the challenge of maintaining some control over impoundment actions while still allowing sufficient discretion for the president during budget implementation. This article examines the events leading up to the passage of the Impoundment Control Act as Title X of the Congressional Budget and Impoundment Control Act of 1974, and the framework established by the law. It provides some analysis of data on rescissions and deferrals in the period from 1975–1995 and reviews efforts to grant the president expanded impoundment authority, culminating in the passage of the Line Item Veto Act of 1996. On April 10, 1997, the new law was found unconstitutional by a district court, but on June 26 the Supreme Court set aside that earlier decision on jurisdictional grounds, ruling that the plaintiffs (six members of Congress) lacked proper legal standing to bring the case ( Raines v. Byrd , 96–1671). However, the Supreme Court decision was confined to this technical issue and did not address the underlying constitutional questions. Whatever the further legal developments relating to the Line Item Veto Act, the article suggests that the issue of restraining or reviving presidential impoundment power will remain unsettled. 相似文献

Brinig, Holcombe, and Schwartzstein (1993) have argued recently that lobby regulation restricts entry into the population of lobbying organizations, and that the number of lobbying organizations then influences legislative activity. However, they analyze only the relationship between the restrictiveness of lobby regulation and legislative activity, thereby assuming that regulation actually reduces numbers of registered interest organizations. We test this assumption with data on state interest organization populations and find little support for it. We consider several other explanations and comment more generally on the status of institutions and their rules in the study of political phenomena. 相似文献

In policy research a frequent aim is to estimate treatment effects separately by subgroups. This endeavor becomes a methodological challenge when the subgroups are defined by post‐treatment, rather than pre‐treatment, variables because if analyses are performed in the same way as with pre‐treatment variables, causal interpretations are no longer valid. The authors illustrate a new approach to this challenge within the context of the Infant Health and Development Program, a multisite randomized study that provided at‐risk children with intensive, center‐based child care. This strategy is used to examine the differential causal effects of access to high‐quality child care for children who would otherwise have participated in one of three child care options: no non‐maternal care, home‐based non‐maternal care, and center‐based care. Results of this study indicate that children participating in the first two types of care would have gained the most from high‐quality center‐based care and, moreover, would have more consistently retained the bulk of these positive benefits over time. These results may have implications for policy, particularly with regard to the debate about the potential implications of providing universal child care. © 2002 by the Association for Public Policy Analysis and Management. 相似文献

In reviewing a number of marriage and family textbooks, published in the years 1958 through 1970, it was found that the theoretical orientation toward sex roles was generally normative, and that typically sex roles were bifurcated into artificial classificatory types, with highly polarized role properties. The ideological message implicit in such a value context was conservative, strongly urging conformity to status quo sex roles within a rigid family system. 相似文献
