Barriers to Seeking Police Help for Intimate Partner Violence

Intimate partner violence is underreported to police. A study was conducted utilizing focus group methodology to identify women's perceptions of the barriers to seeking police help for intimate partner violence (IPV). Facilitators used a structured format with open-ended questions for five focus group sessions that were recorded and subsequently analyzed using Ethnograph software. Participants were 41 women identified from social service agencies in an urban setting serving IPV women with diverse ethnic and cultural backgrounds. Participants identified many barriers for victims, which fell within the following three themes: (1) Predisposing characteristics — situational and personal factors; (2) fears and negative experiences with police response; and (3) fears of possible repercussions. Participants also described positive experiences with police and generated a wish list for improving police response to IPV. Policies and actions that can be taken by police and social service agencies to address the barriers IPV victims face in seeking police help are discussed.     

Identification of Acer rubrum using amplified fragment length polymorphism

Amplified fragment length polymorphism (AFLP) analysis of botanical forensic evidence provides a means of obtaining a reproducible DNA profile in a relatively short period of time in species for which no sequence information is available. AFLP profiles were obtained for 40 Acer rubrum trees. Leaf material from five additional species was also typed. Genomic DNA was isolated using the DNeasy Plant Miniprep Kit (Qiagen, Valencia, CA), double-digested by two restriction endonucleases (EcoRI and MseI) and ligated to oligonucleotide adapters. Two consecutive PCR reactions (pre-amplification and selective amplification) were performed using a modification of the AFLP protocol described by Gibco (Invitrogen, Rockville, MD). The DNA fragments were separated by capillary electrophoresis using the CEQ 8000 DNA Fragment Analyzer. A number of Acer rubrum species-specific peaks were identified. In addition, within this closed set of samples, 15 of 16 (93.8%) blind samples were correctly identified. AFLP data can be used to determine the species of botanical evidence or to associate a sample to a source. This information can be used in forensic investigations to link a piece of evidence with a particular location or suspect.     

Allele frequencies for 27 Y-STR loci with U.S. Caucasian, African American, and Hispanic samples

A total of 263 U.S. Caucasians, 260 African Americans and 140 U.S. Hispanics or a subset of 31 Caucasians, 32 African Americans, and 32 Hispanics were typed for 27 Y-chromosome short tandem repeat (Y-STR) markers: DYS444, DYS446, DYS449, DYS463, DYS485, DYS490, DYS495, DYS504, DYS505, DYS508, DYS520, DYS522, DYS525, DYS532, DYS533, DYS534, DYS540, DYS556, DYS557, DYS570, DYS575, DYS576, DYS594, DYS632, DYS635, DYS641, and DYS643. Allele frequencies for each locus are reported along with nomenclature based on sequence analysis.     

Psychological Distress Following Suicidality Among Gay,Lesbian, and Bisexual Youths: Role of Social Relationships

Longitudinal relations between past suicidality and subsequent changes in psychological distress at follow-up were examined among gay, lesbian, and bisexual (GLB) youths, as were psychosocial factors (e.g., self-esteem, social support, negative social relationships) that might mediate or moderate this relation. Past suicide attempters were found to have higher levels of depressive symptoms, anxious symptoms, and conduct problems at a later time than youths who neither attempted nor ideated. Psychosocial factors failed to mediate this relation. The interaction among past suicidality, social support, and negative relationships was associated with subsequent changes in all 3 psychological distress indicators 6 months later. Specifically, high levels of support (either from family or friends) or negative relationships were found to predict increased psychological distress among those with a history of suicide attempts, but not among youths without a history of suicidality. The findings suggest that GLB youths who attempt suicide continue to have elevated levels of psychological distress long after their attempt and they highlight the importance of social relationships in the youths psychological distress at follow-up.Earlier versions of this paper were presented at the biannual meeting of the European Association for Research on Adolescence, Oxford, UK, September 2002; and, at the annual meeting of the American Public Health Association, San Francisco, CA, November 2003.Associate Professor of Psychology, The City University of New York—The City College and Graduate Center.

The cost-effectiveness of methanol for reducing motor vehicle emissions and urban ozone

This article analyzes the costs and emissions characteristics of methanol vehicles. The cost-effectiveness of methanol—the cost per ton of reactive hydrocarbon emissions reduced—is calculated and compared to the cost-effectiveness of other hydrocarbon reduction strategies. Methanol is found to cost from $33,000 to nearly $60,000 per ton, while several other options are available for under $10,000 per ton. The cost per part-per-million reduction in peak ambient ozone levels is also computed for two cities, Houston and Philadelphia. Despite the greater improvement in ozone in Philadelphia than Houston, methanol is found to be more cost-effective in Houston. This result occurs because Houston's distribution and marketing costs are lower than Philadelphia's. The costs in both cities, however, are far higher than estimates of the benefits from acute health improvements. Finally, the reduction in ozone exposure in Los Angeles is estimated and the costs of the reduction compared with an estimate of acute health benefits. Again, the benefits fall far short of the costs.

Radioimmunological determination of cocaine in human hair

A simple procedure for the determination of cocaine in human hair was described. After washing hair samples were crushed in 0.1 m HCl and incubated overnight at 45 degrees C. The acid extracts were neutralized with 1 m NaOH. Phosphate buffer (pH 7.4) was added to the extracts. The cocaine concentrations were measured by radioimmunoassay. Detection in hair was achieved in all hair samples obtained from cocaine users. This method appears to be suitable for the routine determination of cocaine.
