Comparing ethics education in medicine and law: combining the best of both worlds

This article compares various models of ethics education and how these models are employed by both medical schools and law schools. The authors suggest ways in which each profession can enhance their ethical teaching and argue that ethics education in both medicine and law should combine the best elements of each education model, thereby producing graduates who are more knowledgeable and appreciative of ethical issues in practice.     

A validation study for duct tape end matches

Fracture matches are considered to be the strongest association achievable in forensic examinations of glass, metal, wood, plastic, paint, tape, and other trace evidence. Despite being fairly routine examinations, few publications exist to support their admissibility in court. This study was designed, using duct tape as the fractured medium, to determine the validity and error rate associated with conducting end match (fracture match) examinations on this material. Five test designs, which varied either the source roll of tape or manner of separation (torn or cut) from the roll, were administered to four analysts with instructions to examine the assigned test sets for end matches. If an end match was not identified by the initial analyst, the entire test set was independently evaluated by the remaining three analysts. Results indicated that while tape grade did not hinder end match identification, the manner of separation could affect results.     

Immunohistochemical staining as a potential method for the identification of vaginal epithelial cells in forensic casework

There is currently no accurate method to identify vaginal epithelial cells uniquely. This study aimed to use a cell extraction procedure compatible with routine forensic sampling methods, and to investigate the expression of cytokeratin (CK), estrogen receptor-alpha (ERalpha), and phosphodiesterase 5 (PDE5) in order to distinguish between skin, buccal, vaginal, and external penile epithelial cells. Seminal fluid samples were also examined. Epithelial cell samples were fixed in formalin, embedded in agarose, and processed using histological methods. Antigen-antibody reactions were detected using the DAKO Envision+ detection system. CK was present in all cells from all five sources confirming the origin of cells as epithelial. Both ERalpha and PDE5 positively labeled vaginal, buccal, and skin epithelial cells. Although an antigen unique to vaginal epithelial cells was not identified, we have described a cell extraction procedure for use in the immunohistochemical detection of a wide range of antigens, an approach compatible with forensic diagnostics.     

Decision-Making About Volitional Impairment in Sexually Violent Predators

The Kansas v. Hendricks (1997) decision, in which the Supreme Court authorized post-sentence civil commitment for certain sex offenders, appeared to be constitutionally legitimized by limiting the class of offenders eligible for this special form of civil commitment to those who are "unable to control" their dangerousness. Nowhere in the available record, however, did the Court elucidate what they meant by this notion of volitional impairment. This study sought to examine factors that legal professionals (n=43), psychologists (n=40), and mock jurors (n=76) deem most relevant to a determination of sex offender volitional impairment. Participants, who were randomly assigned to a sexual predator commitment or an insanity hearing context, read a series of 16 vignettes that described a pedophilic offender and included combinations of variables hypothesized to be related to judgments of volitional impairment. Results suggested that participants, who as a group made remarkably high estimates of likelihood of future sexual violence, considered verbalization of control, history of sexual violence, and the context of the hearing as highly relevant to determinations of volitional impairment. Implications for policy and practice are explored.     

Violence against women associated with arrests for sex trade but not drug charges

The current study was designed to examine associations between gender-based violence and arrests due to sex trade or drug-related charges among a statewide sample of incarcerated women in Rhode Island. Incarcerated women were asked to participate in brief pre- and posttest surveys of their experiences of violence, sexual risk and substance use behaviors, as part of a study on the effectiveness of a family planning program in a state correctional facility; data from pretest surveys (N=447) were used for current analyses. Logistic regression analyses adjusted for demographics were used to assess significant associations between gender-based violence variables (i.e., adolescent intimate partner violence (IPV), adult IPV, childhood sexual assault (SA), adolescent SA, and adult SA) and arrests due to sex trade or drug-related charges. Significant relationships were observed between arrests for sex trade and adult SA (OR=2.1, 95%CI=1.2-3.6), adolescent IPV (OR=2.5, 95%CI=1.5-4.1), and adult IPV (OR=1.7, 95%CI=1.1-2.6); no significant associations were observed for drug-related charges. Findings from the current study demonstrate that experiences of gender-based violence are associated with arrests for sex trade but not drug-related charges. Interventions for incarcerated women are needed to consider and address history of victimization from gender-based violence and its relation to women's historic and future sex trade involvement.     

Teaching Young Children to Discriminate Abusive From Nonabusive Situations Using Multiple Exemplars in a Modified Discrete Trial Teaching Format

Personal safety programs can teach young children knowledge and skills they can utilize to avoid or escape abduction and sexual abuse (Wurtele, 1990). An appropriate escape response will not occur, however, if the child is unable to discriminate an innocuous situation from a potentially abusive one. This study examines the crucial elements involved in training the recognition or discrimination phase in personal safety programs. A multiple probe design across three typically developing children, ages 5-years 7-months through 6-years 7-months, was used to determine whether rules and discrete trial training of discriminations of appropriate and inappropriate touch and situations generalized to puppet role-play scenarios. All participants showed increases in correct responding on generalization role-play probes and maintained these increases over a 3-and 6-week follow-up.     

Why do evaluation researchers in crime and justice choose non-experimental methods?

Despite the general theoretical support for the value and use of randomized controlled experiments in determining ‘what works’ in criminal justice interventions, they are infrequently used in practice. Reasons often given for their rare use include that experiments present practical difficulties and ethical challenges or tend to over-simplify complex social processes. However, there may be other reasons why experiments are not chosen when studying criminal justice-related programs. This study reports the findings of a survey of criminal justice evaluation researchers as to their methodological choices for research studies they were involved in. The results suggest that traditional objections to experiments may not be as salient as initially believed and that funding agency pressure as well as academic mentorship may have important influences on the use of randomized controlled designs.In August 2005, Dr. Lum’s affiliation will change to George Mason University.
