DNA statistics in the Simpson matter.

Abstract

On 3 October 1995, O.J. Simpson was acquitted of two murders in spite of very strong DNA evidence linking his blood to the crime. Although numerical statements describing the strength of this evidence were made, the DNA profiles included so many loci that the need for presenting numbers in this case, and in others using similarly high numbers of loci, is probably unnecessary. If numbers are to be presented, however, they should be given in the form of likelihood ratios. One thing the verdict in the Simpson case makes clear is that it is essential that the integrity of DNA evidence (with regard to collection, potential contamination or tampering) be beyond doubt.

Coding-complete genome sequence of grapevine leafroll-associated virus 13 from grapevine in California.

In this study, we report the coding-complete genome sequence of Grapevine leafroll-associated virus 13 (GLRaV-13), isolate CA8881, detected in Vitis vinifera in California, USA. The genome sequence exhibited over 95% nucleotide identity with previously reported GLRaV-13 isolates and contributed to better understanding of the genetic diversity of ampeloviruses infecting grapevine.

Increasing syringe access and HIV prevention in California: findings from a survey of local health jurisdiction key personnel.

This article presents results from the first survey of California local health jurisdictions (LHJs) subsequent to passage of legislation that allows for over-the-counter pharmacy sales of syringes. In 2004 Governor Arnold Schwarzenegger signed Senate Bill 1159 (SB1159) into law to "prevent the spread of HIV, hepatitis and other blood-borne disease among drug users, their sexual partners and their children." This legislation permits counties and cities to authorize a local disease prevention demonstration project (DPDP). Once authorized, a DPDP permits individuals to legally purchase and possess up to ten syringes from registered pharmacies without a doctor's prescription. From June to August 2005, we surveyed health departments in all 61 LHJs to assess implementation status of SB1159. Fifty-seven (93%) LHJs responded. Nine (16%) had approved a DPDP by August 2005, 17 (30%) were in the process of obtaining authorization, and 18 (32%) anticipated that SB1159 would never be authorized in their LHJ. Among LHJs that do not plan to approve a DPDP (n = 18), the reasons included: strong community opposition (41%), competing priorities (35%), law enforcement opposition (29%), and little or no interest among pharmacies (29%). In LHJs that have authorized a DPDP, 31.4% of pharmacies registered to legally sell nonprescription syringes. Preliminary results indicate that local coalitions, comprised of public health, waste management and pharmacy officials, have been instrumental in facilitating DPDP authorization. Further research is needed to identify facilitators and barriers to adopting SB1159, to identify areas for improving technical assistance to implementers, and to assess the public health impact of the legislation.

Acción Mutua (Shared Action): a multipronged approach to delivering capacity-building assistance to agencies serving Latino communities in the United States.

Culturally appropriate, theory-based capacity-building assistance can serve a vital role in helping HIV prevention providers remain up-to-date, effective, and responsive to those they serve. Funded by the Centers for Disease Control and Prevention (CDC), AIDS Project Los Angeles, in collaboration with San Francisco State University's César E. Chávez Institute, conducted full-day site visits and qualitative interviews in 2005 with mid-level management staff of CDC-funded community-based organizations delivering HIV prevention services to Latino communities in the western region of the United States. We found that agencies we visited (1) had not yet adapted the evidence-based interventions they were using at the time of our visit and (2) requested technical assistance and training in the areas of program development, evaluation, group facilitation techniques, consumer recruitment, client retention, intervention adaptation, and materials development. Findings from this needs assessment were used to inform our seven-pronged approach to delivering capacity-building assistance entitled "Acción Mutua" (Shared Action). The approach emphasizes strategic partnerships, stakeholder involvement, organizational self-assessment, culturally appropriate materials development, interactive training, tailored onsite technical assistance, and professional networking opportunities. This article describes our approach in detail, the assessment process we used to develop it, and its implications for capacity-building practice.
