Nanotechnology: The Challenge of Regulating Known Unknowns

Media reports of the health hazards posed by nano-sized particles (NSPs) have turned a white hot spotlight on the risks of nanotechnology. Worried about the risks posed to workers producing nano-materials, the Washington Post has labeled nanotechnology a "seat-of-the-pants occupational health experiment." This article examines our emerging knowledge base about the hazards of two types of exposure: inhalation of NSPs and topical application of products containing NSPs. It argues that a clear-eyed evaluation of the benefits and risks of nanotechnology is made extremely difficult by the marriage of a complex science with a venture capitalist-like hype. It then suggests that, absent additional statutory authority, governmental regulators cannot readily address the risks posed by these products. This regulatory inaction leaves a significant role for the private insurance market, a role that regulators should support in tangible ways outlined in the article.     

Validation of the Cozart Amphetamine Microplate EIA for the analysis of amphetamines in oral fluid

The purpose of this study was to determine the performance characteristics of the Cozart Amphetamine Microplate EIA for detecting amphetamine in oral fluid. Oral fluid samples were collected using the Cozart RapiScan Collection System from 135 volunteer donors from drug treatment clinics. A further 35 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory using the Cozart Amphetamine Microplate EIA and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen until analysis by GC-MS. The intra-assay precision for the Cozart Amphetamine Microplate EIA for amphetamine in oral fluid over forty assays was 2.74-7.1% CV (within assay) and 3.4-7.0% CV (within day). A total of 78 samples were positive for various amphetamines and related designer drugs. The Cozart Amphetamine Microplate EIA, using a cutoff of 45 ng/ml amphetamine equivalents in neat oral fluid, had a sensitivity of 91.7+/-3.3% and a specificity of 95.9+/-1.9% versus GC-MS using a cutoff of 30 ng/ml. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result.     

Perception of and Satisfaction with Relationship Power,Sex, and Attachment Styles: A Couples Level Analysis

Eighty heterosexual dating couples provided information about their gender, individual histories of abuse in their current relationship, attachment styles, perception of and satisfaction with relationship power. Partner report of physical abuse was the dependent variable. APIM actor results suggest that an individual's gender interacts with perceived level of relationship power and satisfaction with relationship power for physical abuse. Both dimensions of attachment interacted with perceived relationship power for physical abuse. Partner effects were also found. One's partner's sex interacted with perceived power and satisfaction with relationship power. Finally, the partner's avoidant attachment interacted with satisfaction with relationship power. These findings generally replicate and extend the work of H. M. Ronfeldt, R. Kimerling, and I. Arias (1998, J. Marriage Fam. 60: 70–78) by showing how attachment styles, perception of relationship power, and satisfaction with relationship power are related in predicting aggression against a romantic partner.     

Cognitive-behavioral rehabilitation for high-risk violent offenders: an outcome evaluation of the violence prevention unit

Rehabilitation programs for adult violent offending are still novel, and few published studies examine the recidivism outcomes of those who complete such programs. This study describes a New Zealand prison program for high-risk violent men. The program is intensive and cognitive behavioral. Preliminary outcome data are presented for three indices during 2 or more years of follow-up: nonviolent reconviction, violent reconviction, and subsequent imprisonment. In comparison with untreated offenders, treated men were less likely to be reconvicted of a violent offense, and those who were took longer to fail. There was also a 12% difference in favor of the treated men on the two other indices, nonviolent reconviction and reimprisonment. The authors conclude that the program shows early promise and that further evaluation with a larger sample of treated men will be important in clarifying whether the program is having a differential impact on violent versus nonviolent offending.     

Do Women Representatives Regender Legislative Bureaucracy? Assessing the Effect of Representative Sex on Women's Presence among US Congressional Staff

Achieving greater female presence in influential positions is a commonly discussed strategy for gender reform in institutions such as the US Congress. Using theory adapted from research on gender in the workplace, this study examines whether women representatives, as ‘managers’ of congressional offices, alter patterns of gender representation in Congress by hiring and promoting more women staffers compared with men representatives. Cross-sectional logistic regression analyses of staffer sex during the 110th and 111th Congresses (2007–10) reveal a positive relationship between women representatives and female presence on congressional staffs. However, the relationship does not hold with respect to the most influential staff positions. These findings provide only limited support for theories that women representatives act as ‘change agents’ by directly facilitating opportunities for women, and highlight the importance of exploring alternative strategies for empowering women and regendering legislative institutions.     

Effectiveness of modified therapeutic community treatment within a medium-secure service for personality-disordered offenders

There is debate as to whether secure hospital treatment for offenders with personality disorder can be effective relative to criminal justice interventions. This study examines the evidence for long-term treatment of such offenders in hospital within in a modified therapeutic community model including accredited offending behaviour programmes. A panel sample of 47 patients were followed up on measures of violence risk (HCR-20, VRS) and symptom severity (SCL90-R). Intention-to-treat analysis with reliability thresholds showed significant positive change between assessment and discharge in both violence risk (VRS) and symptoms (SCL90-R) indicating a positive treatment effect. Threshold effects for treatment effectiveness seemed to occur at 1?year of treatment for risk and 3?years for symptom reduction.
