Effectiveness of hotline, advocacy, counseling, and shelter services for victims of domestic violence: a statewide evaluation

The authors report the results of an evaluation of services provided by 54 Illinois domestic violence agencies. In collaboration with the University of Illinois at Chicago evaluation team, domestic violence advocates identified services to be evaluated, specified desired outcomes of those services, and participated in developing measures of those outcomes in both English and Spanish. With in the limitations of the study, outcomes were positive in all four program areas: hotline, counseling, advocacy, and shelter. The authors then discuss implications for evaluation of domestic violence programs that maintain victim safety as a guiding principle.     

Postmortem findings of the victims of the Jonestown tragedy

The procedure for processing and identifying the victims of the Jonestown, Guyana tragedy is outlined. Autopsies were performed on seven of the victims, and the autopsy anatomic and toxicologic findings are presented. Problems encountered in the interpretation of the autopsy findings are noted.     

The tools to understand: community as co-researcher on culture-specific protective factors for Alaska Natives

A collaborative research process engaging Alaska Native communities in the study of protective factors in Alaska Native sobriety and the design of a preventative intervention using its findings is described. Study 1 was discovery oriented qualitative research whose objectives were identification of protective factors and development of a heuristic model. Study 2 involved quantitative survey methods to develop and test ameasure of protective factors identified by the qualitative study. Empirical data from these studies is presented, and the role of Alaska Native co-researchers who did not possess specialist research training is described in the design and implementation of the study, interpretation of findings, and design of the intervention model and tools. Benefits that emerged from co-researcher involvement in this process, to the community and to the co-researchers themselves, are described.     

Attributions for fair exchange outcomes: The effects of power and status

This study focuses on how two fundamental social factors, structural power position and social status, affect attributions for relatively common, non-problematic exchange outcomes. We argue that the relative power and statuses of dyad members activate expectations of competence which in turn shape attributions in the situation. Subjects assumed the role of a typist described in a vignette of a transaction between a typist and a student needing a paper typed. We manipulated power positions in the vignette by varying the value and availability of the resource each actor desired; subject's sex and that of the fictive student represented social statuses. Despite the typicality of the exchange situation, results indicated that status and, to some extent power, created variation in the strength of attributions for the exchange outcome. Females, presumably expected to be more competent typists, made stronger self-attributions for the typing payment than males. Similarly, those in high power positions tended to attribute the payment more to themselves than occupants of low power positions.     

How the probability of a false positive affects the value of DNA evidence

Errors in sample handling or test interpretation may cause false positives in forensic DNA testing. This article uses a Bayesian model to show how the potential for a false positive affects the evidentiary value of DNA evidence and the sufficiency of DNA evidence to meet traditional legal standards for conviction. The Bayesian analysis is contrasted with the "false positive fallacy," an intuitively appealing but erroneous alternative interpretation. The findings show the importance of having accurate information about both the random match probability and the false positive probability when evaluating DNA evidence. It is argued that ignoring or underestimating the potential for a false positive can lead to serious errors of interpretation, particularly when the suspect is identified through a "DNA dragnet" or database search, and that ignorance of the true rate of error creates an important element of uncertainty about the value of DNA evidence.     

A simple DNA extraction method for marijuana samples used in amplified fragment length polymorphism (AFLP) analysis

As a first step in developing a molecular method for the individualization of marijuana samples, we evaluated a plant DNA extraction kit. The QIAGEN plant DNeasy method uses a spin column format for recovery of DNA and is effective for obtaining high molecular weight DNA from leaf, flower (bud), and seed samples of marijuana. The average DNA yield was 125-500 ng per 100 milligrams of fresh plant tissue. The recovered DNA was of polymerase chain reaction (PCR) quality as measured by the ability to generate reproducible amplified fragment length polymorphism (AFLP) profiles. AFLP is a technique used to create a DNA profile for plant varieties and is being applied to marijuana samples by the authors to link growers and distributors of clonal material. The QIAGEN plant DNeasy method was simple, efficient, and reproducible for processing small quantities of marijuana into DNA.
