Removing and identifying drug contamination in the analysis of human hair

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.     

The Spatial Patterning of County Homicide Rates: An Application of Exploratory Spatial Data Analysis

The possibility that homicides can spread from one geographic area toanother has been entertained for some time by social scientists, yetsystematic efforts to demonstrate the existence, or estimate the strength,of such a diffusion process are just beginning. This paper uses exploratoryspatial data analysis (ESDA) to examine the distribution of homicides in 78counties in, or around, the St. Louis metropolitan area for two timeperiods: a period of relatively stable homicide (1984–1988) and aperiod of generally increasing homicide (1988–1993). The findingsreveal that homicides are distributed nonrandomly, suggestive of positivespatial autocorrelation. Moreover, changes over time in the distribution ofhomicides suggest the possible diffusion of lethal violence out of onecounty containing a medium-sized city (Macon County) into two nearbycounties (Morgan and Sangamon Counties) located to the west. Althoughtraditional correlates of homicide do not account for its nonrandom spatialdistribution across counties, we find some evidence that more affluentareas, or those more rural or agricultural areas, serve as barriers againstthe diffusion of homicides. The patterns of spatial distribution revealedthrough ESDA provide an empirical foundation for the specification ofmultivariate models which can provide formal tests for diffusion processes.     

The Impoundment Control Act of 1974: Restraining or Reviving Presidential Power?

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.     

How some rules just don't matter: The regulation of lobbyists

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.     

Reducing Adolescents’ Perceived Barriers to Treatment and Increasing Help-seeking Intentions: Effects of Classroom Presentations by General Practitioners

The Building Bridges to General Practice (BBGP) program is an outreach initiative. It aims to reduce young peoples’ perceived knowledge- and belief-based barriers to engaging in treatment and to increase their behavioral intentions to consult a general medical practitioner (GP) for physical and psychological problems. By increasing intentions, the BBGP program aims to increase actual consultations with a GP for both types of problem. A quasi-experimental nested design was used to evaluate the effect of the intervention in three Australian high schools. A Treatment group (n = 173, M = 16 years) and Comparison group (n = 118, M = 15 years) completed questionnaires of perceived barriers, intentions and self-reported consultations with a GP. Questionnaires were completed 1 week before the intervention, 5 then 10 weeks post-intervention. The Treatment group, but not the Comparison group, showed reductions in perceived barriers over time, increased intentions to consult a GP for psychological problems and a significant correlation between intentions and subsequent GP consultations. Results support the utility of the intervention for improving adolescents’ beliefs, intentions and behavior related to consulting a GP for physical and psychological problems.

Reconsidering The Counter-Mobilization Hypothesis: Health Policy Lobbying In The American States

Despite its widespread use since the concept was introduced by David Truman (1951. The Governmental Process. New York: Alfred A. Knopf), counter-mobilization by organized interests has remained theoretically ambiguous and rarely studied empirically. We more fully develop the concept of short-term counter-mobilization, distinguish it from long-term counter-mobilization, specify the conditions under which we might observe short-term counter-mobilization, and test the resulting hypotheses with data on health care lobby registrations in the American states during the late 1990s. We find little evidence of short-term counter-mobilization among health interest organizations, which leads us to more fully consider several null hypotheses about the limits of strategic behavior on the part of organized interests.An earlier version of this paper was prepared for presentation at the Annual Meeting of the Midwest Political Science Association, Chicago, April 2004. This research was supported by a Robert Wood Johnson Foundation Investigator Award in Health Policy Research (ID#047727).     

Narcotization as Security Dilemma: The FARC and Drug Trade in Colombia

This article addresses the relationship between the Revolutionary Armed Forces of Colombia (FARC) and the cocaine trade in Colombia, and implications for the FARC's complete demobilization under the 2016 peace agreement. The article identifies two phases of FARC interaction with drug markets. During the regulation phase (1982–1991), the FARC regulated the coca economy and charged protection rents. During vertical integration (1991–present), the FARC directly participated in drug markets. Contrary to conventional approaches, the article adopts the concept of the security dilemma to argue that FARC integration in drug markets was a strategic response to threats from paramilitaries and narcotics traffickers.     

The effect of respondents' just world beliefs and target person's social worth and awareness-of-risk on perceptions of a person with AIDS

The present research examined how individuals' just world beliefs affected their perceptions of a person with AIDS who was depicted as having contracted the HIV virus while either aware or unaware of health risks, and who was defined as either high or low in general social deservingness or worth. Dependent variables included respondents' affective reactions to the person with AIDS, their willingness to allocate resources to him, and their perception of the fairness or the unfairness both of his general plight and that various types of resources be given to him. Results indicated that those who were higher in just world beliefs were more emotionally negative to the other with AIDS, they were less willing to contribute resources to him, and they felt that it was less fair that such resource transfers be required. Similar response patterns were found when the other with AIDS was described as lower in social worth and when he was depicted as having contracted AIDS with full awareness of health risks. Implications of the findings were discussed in terms of how psychological theories of justice might inform health care policy.
