Perceptions of help resources for victims of intimate partner violence

Intimate partner violence (IPV) constitutes a major public health problem in the United States. This cross-sectional survey of 108 emergency department (ED) care providers and 146 ED visitors at three metropolitan EDs compared the beliefs of ED health care providers with those of community members about the relative benefits of the helpfulness of resources for IPV victims using hypothetical case scenarios. Although providers generally indicated that help resources were helpful in all scenarios, visitors were more discriminating, showing less support for resources in the lower-risk scenario. Regarding differences between groups, visitors selected police and attorneys more frequently than providers as a helpful resource, whereas providers selected shelters and counselors more frequently than visitors. Adjustment for previous experience with IPV did not change these results. Understanding the differences between health care providers' and community members' perceptions of resources for victims of IPV may improve the effectiveness of referral to IPV resources.     

What Makes a Good Alibi? A Proposed Taxonomy

A taxonomy of alibis is proposed involving two forms of supporting proof: physical evidence and person evidence. Levels of physical evidence and person evidence were combined to create 12 cells in the taxonomy. Participants (n = 252), who were asked to assume the role of detectives, evaluated alibis representing these 12 cells. The believability of the alibis generally followed the taxonomy's predicted pattern, but physical evidence, when present, tended to overwhelm the person evidence more than had been expected. In addition, alibi evaluators seemed to not consider the possibility that a stranger who corroborated an alibi might be mistaken about the identity of the person. Trait inferences regarding the alibi providers tended to follow the believability data, even when the traits themselves were not relevant to believability of the alibi. We call for the development of a literature on the psychology of alibis, recommend the taxonomy as a framework, and suggest several avenues of inquiry.     

Comprehensive evaluation: a holistic approach to evaluating domestic violence offender programmes

This article argues that the focus on behavioural outcomes in evaluations of domestic violence offender programmes has been too narrow, and that a more holistic approach incorporating investigation of the psychological characteristics of offenders and treatment characteristics may be required to determine what works, for whom, and under what circumstances. To this end, one interpretation of a comprehensive evaluation framework is outlined. The article hypothesises the insights to be gained by assessing the contribution of several potential mediating variables of the treatment process in the evaluation of these programmes. These variables are the heterogeneity of treatment targets in the target population; motivation to change; programme integrity variables; and therapeutic factors. The article concludes that only by implementing theoretically informed, multifaceted evaluations will we move closer to understanding the process of successful rehabilitation.     

Characterization and validation studies of powerPlex 2.1, a nine-locus short tandem repeat (STR) multiplex system and penta D monoplex

In order to increase the power of discrimination for human identification purposes, a nine-locus short tandem repeat (STR) multiplex, the GenePrint PowerPlex 2.1 system (PowerPlex 2.1) developed by Promega Corporation and a separate pentanucleotide-repeat locus, Penta D, were tested. This megaplex system includes the highly polymorphic loci FGA, TPOX, D8S1179, vWA, Penta E, D18S51, D21S11, TH01, and D3S1358 and may be used in combination with the eight-locus STR multiplex, the GenePrint PowerPlex 1.1 system (PowerPlex 1.1) that has been previously developed. Three of the loci, TPOX, TH01 and vWA, have been included in both systems for quality control purposes. As with PowerPlex 1.1, PowerPlex 2.1 is also based on a two-color detection of fluorescent-labeled DNA products amplified by polymerase chain reaction (PCR) and provides a valuable tool for accurate and rapid allele determination. The primer sequences used in the PowerPlex 2.1/Penta D system are also presented in this report. To meet the "Quality Assurance Standards for Forensic DNA Testing Laboratories" (FBI), we tested the efficiency and reproducibility of the PowerPlex 2.1/PentaD system by several validation studies that were conducted as a joint project among seven laboratories. Validation tests included concordance studies, sensitivity, and species specificity determination, as well as performance in forensic and environmentally impacted samples. The results produced from these tests demonstrated the consistency and reliability of the PowerPlex 2.1/Penta D system.     

The (Un)Acceptability of Betrayal: A Study of College Students' Evaluations of Sexual Betrayal by a Romantic Partner and Betrayal of a Friend's Confidence

Because loyalty and trust are viewed as key requirements for relationships with friends as well as with romantic partners, acts of betrayal, which violate the trust on which these relationships are based, are viewed as serious transgressions. This study focused on 2 commonly occurring kinds of betrayal—betrayal of a friend's confidence despite a promise not to do so and sexual betrayal by a romantic partner despite an agreement to be monogamous. Approximately 261 college students, aged 18 to 23, answered questions concerning the acceptability of betrayal under a variety of different conditions and described their self-restraint, tolerance of deviation, and betrayal behavior. Despite pervasive disapproval of betrayal, the extent of disapproval was a function of the type of betrayal (whether of a romantic partner or a same-sex friend), the justification for the betrayal, the sex of the transgressor, and the characteristics of the respondent. There was greater acceptance of sexual betrayal than betrayal of a friend's confidence, of male than female transgression, and by male than female respondents. These results are largely accounted for by the finding that male respondents gave high ratings of acceptance of sexual betrayal by male transgressors. Acceptance of both forms of betrayal was correlated with lack of self-restraint, tolerance of deviation, and behavioral betrayal.     

The Bottom Line: The Effect of Written Expert Witness Statements on Juror Verdicts and Information Processing

Mock jurors recruited from jury rolls were either not given written statements of expert witnesses' direct testimony or were provided with such statements before or after the presentation of that testimony. Presentation of the statements before the testimony and cross-examination provided jurors with a schema that allowed them to distinguish more effectively among the claims of four differentially worthy plaintiffs because they processed more probative evidence than other jurors. Jurors in receipt of written statements before the testimony found the evidence to be more comprehensible than other jurors. Jurors provided with written statements following testimony and cross-examination were able to differentiate between the most and least severely injured plaintiffs, whereas jurors not in receipt of any written statements were unable to differentiate among any of the differentially worthy claimants. The limitations of this case management technique and of the study are discussed.
