Hair analysis: self-reported use of "speed" and "ecstasy" compared with laboratory findings

Drug use histories were collected from 100 subjects recruited from the "dance scene" in and around Glasgow, Scotland. In addition, each subject donated a hair sample which was analyzed by gas chromatography/mass spectrometry (GC/MS) for amphetamine (AP), methamphetamine (MA), 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MD MA) and 3,4-methylenedioxyethylamphetamine (MDEA). The hair samples were analyzed in two 6 cm segments or in full, ranging from 1.5 to 12 cm depending on the length of the hair. Approximately 10 mg of hair was ground to a fine powder before treatment with beta-glucuronidase/aryl sulfatase. A solid-phase extraction procedure was carried out followed by derivatization with pentafluoropropionic anhydride (PFPA). All extracts were analyzed by gas chromatography/mass spectrometry (GC/MS). Of the 139 segments analyzed, 77 (52.5%) were positive for at least one of the five amphetamines. The drug concentrations found in the hair were compared with the self-reported drug histories. A concordance of greater than 50% was found between the self-report data and levels detected in hair. However, no correlation was found between the reported number of "ecstasy" tablets consumed and the drug levels detected in hair. An increase in the average drug levels measured was observed from low to high use (number of "ecstasy" tablets/month). A large number of false negatives and a low number of false positives were observed.     

Resistance of degraded hair shafts to contaminant DNA

We have investigated the susceptibility of degraded human hair shaft samples to contamination by exogenous sources of DNA, including blood, saliva, skin cells, and purified DNA. The results indicate that on the whole hair shafts are either largely resistant to penetration by contaminant DNA, or extremely easy to successfully decontaminate. This pertains to samples that are both morphologically and biochemically degraded. We suggest that this resistance to the incorporation of contaminant DNA relates to the hydrophobic and impermeable nature of the keratin structures forming the hair shaft. Therefore, hair samples represent an important and underestimated source of DNA in both forensic and ancient DNA studies.     

Nonviolent offenders' and college students' attachment and social support behaviors: implications for counseling

This study examines the relationships between adult attachment orientations and the ability to seek social support as factors in mediating behavior. Data were collected on non violent offenders (n = 57) and college students (n = 89). The results indicated the non-normative group of nonviolent offenders reported being more securely attached and having more satisfaction with their social supports than the normative group of college students. Fewer college students reported being securely attached than the nonviolent offenders but had a larger number of social supports. In the insecure categories, nonviolent offenders reported being more dismissively attached whereas college students reported being preoccupied in their attachment orientation. The study suggests that attachment and social-support-seeking behaviors across different populations may be potential factors in designing counseling services that are used for risk classification and needs assessment.     

Advances in the assessment and prediction of interpersonal violence

This article underscores the weakness of clinical judgment as a mechanism for prediction with examples from other areas in the psychological literature. Clinical judgment has as its Achilles'heel the reliance on a person to incorporate multiple pieces of information while overcoming human judgment errors--a feat insurmountable thus far. The actuarial approach to risk assessment has overcome many of the weaknesses of clinical judgment and has been shown to be a much superior method. Nonetheless, the static/historical nature of the risk factors associated with most actuarial approaches is limiting. Advances in risk prediction will be found in part in the development of dynamic actuarial instruments that will measure both static/historical and changeable risk factors. The dynamic risk factors can be reevaluated on an ongoing basis, and it is proposed that the level of change in dynamic factors necessary to represent a significant change in overall risk will be an interactive function with static risk factors.     

Understanding the historical turn in the policy sciences: A critique of stochastic, narrative, path dependency and process-sequencing models of policy-making over time

This article evaluates four general models of historical change processes which have emerged in various fields in the social sciences – namely stochastic, historical narrative, path dependency and process sequencing – and their application to the study of public policy-making. The article sets out and assesses the merits and evidence for each, both in general social research and in the policy sciences. The article suggests that more work needs to be done examining the assumptions and presuppositions of each model before it can be concluded that any represents the general case in policy processes. However, since neither the irreversible linear reality assumed by narrative models, nor the random and chaotic world assumed by stochastic models, nor the contingent turning points and irreversible trajectories required of the path dependency model are found very often in policy-making, these models are likely to remain less significant than process-sequencing models in describing the overall general pattern of policy dynamics.     

Citizen-Centered Collaborative Public Management

Civic engagement and collaborative public management are concepts that are defined broadly, making theoretical explication challenging and practical application of empirical research difficult. In this article, the authors adopt definitions of civic engagement and collaborative public management that are centered on the citizen and the potential for active citizenship. Following a historical review of civic engagement in the United States, a conceptual model of five approaches to civic engagement is offered. Citizen-centered collaborative public management is enhanced through these approaches. The authors suggest the need for further empirical research on collaborative public management that is grounded in citizenship action.     

All Together Now? An Empirical Study of the Voting Behaviors of Homeowner Association Members in St. Louis County

Homeowner associations (HOAs), by design, collect homogenous members of a community into a residential development with defined boundaries and contain at least some very active individuals. This implies that HOAs may lower the transaction costs involved with voting resulting in HOA membership increasing voter participation. Further, as more HOAs provide goods and services to their members as substitutes for goods and services provided by the public sector, one would expect HOA members to vote more conservatively and in support of more privatization. Using a detailed population database constructed for Saint Louis County, Missouri, and results from the November 2004 general election, this article analyzes the effect that living in an HOA has on voter participation and on the results of several election issues. Following a similar study by the Public Policy Institute of California, the results show that, once population characteristics are controlled for, there is no HOA effect on the likelihood of HOA members to vote Republican. Unlike previous work, this study shows that if the vote reporting districts are broken into five mutually exclusive categories rather than using the 60% rule used in other studies, areas with more HOAs do show an increase in participation rates and an increased likelihood to vote against property tax increases. The results hold up even after the presence of spatial autocorrelation is confirmed and controlled for.     

The Australian Public Sector and New Governance

The AJPA resumed publishing the Administrative Chronicle in 1996. Each year the editors invite a distinguished writer to contribute an administrative essay reviewing developments in the previous year. They are asked to examine trends and topics of major importance rather than simply providing a chronology of events. In inviting contributors the editors have attempted to incorporate different views across Australia. Previous chronicles have included J Stewart (55)1; S Prasser (56)1 and J Homeshaw (57)3.
