The effect of sodium fluoride on the stability of cyanide in postmortem blood samples from fire victims

Assigning a level of significance to cyanide concentrations found in the blood of fire victims is often hampered by the fact that cyanide is inherently unstable in cadavers and in stored blood samples. A few researchers have proposed that sodium fluoride can be used to minimize the instability of cyanide in blood samples; however, controlled studies have not been performed to support validation of this hypothesis. To test the sodium fluoride hypothesis, both treated and control blood samples from 14 autopsied fire victims were tested over a 25-30 day period. A 2% concentration of sodium fluoride was added to the blood samples at the start of testing and the samples were refrigerated between testing intervals. Cyanide concentrations in the treated and control samples were measured between 9 and 11 days post treatment and between 25 and 30 days post treatment. A statistically significant difference was not present between blood cyanide concentrations in treated and control samples between 9 and 11 days. During this time period, although there were small statistically significant increases in both treated and untreated samples the fluctuations were minor. Since the treated and control samples did not exhibit instability between 9 and 11 days, it is not surprising that the sodium fluoride appeared to have no effect. However, a statistically significant difference between blood cyanide concentrations in treated and control samples was observed between 25 and 30 days. Those samples treated with sodium fluoride showed a reduction in blood cyanide variability with virtually no overall change, over a 25-30 day period when compared to control samples, while unconditioned samples showed a significant, average increase of 35%. Based on the findings of this study, it is recommended that 2% sodium fluoride be added to blood samples obtained from fire victims to reduce cyanide instability due to bacteriological activity.     

The second-order election model revisited: An experimental test of vote choices in European Parliament elections

This paper examines the micro-foundations of the second-order elections model of European Parliament (EP) elections. We extend the existing literature in several ways. First, we propose an individual-level model of voting behaviour in second-order elections. Second, we present the first study using experimental methods to test the predictions of the second-order model, allowing us to test the individual-level propositions about vote choice in a controlled environment. Importantly, we also examine the conditioning effect of information on the ‘second-order’ nature of voting behaviour in EP elections. Our findings show that while voters base their EP vote choices primarily on domestic preferences, those who are given additional information about the European integration dimension are also more likely to vote on this basis.     

Predictors of Positive Development in Emerging Adulthood

This article responds to recent calls for a focus on successful development in young people and examination of its developmental precursors, in order to identify potentially modifiable targets for interventions. The current study examined child and adolescent precursors of positive functioning in emerging adulthood, including individual characteristics, relationship factors, and connections to the community, using a multidimensional positive development measure at 19–20 years. The sample consisted of 511 males and 647 females who were participants in the Australian Temperament Project, a population based longitudinal study that has followed young people’s psychosocial adjustment from infancy to early adulthood. Higher levels of positive development in emerging adulthood were associated with stronger family and peer relationships, better adjustment to the school setting, higher family socioeconomic status, and better emotional control. Some significant gender differences were observed, with emotional control, family relationships, and community orientation all being stronger predictors of males’ than of females’ positive development. The findings provide possible targets for child and adolescent interventions to promote positive development in early adulthood.     

A REVIEW OF ONLINE DIVORCE EDUCATION PROGRAMS

Divorce education programs first surfaced over four decades ago. Today, many states mandate parents to participate in a divorce education program before their dissolution can be finalized. Changes in the technological landscape have allowed innovative practitioners to create online divorce education programs, yet these programs have not been formally evaluated for quality. Adapting a research design for evaluating face‐to‐face programs, we created an online divorce education review form and reviewed online divorce education programs that parents use to meet court‐mandated requirements. Results reveal that online programs have significant potential to help divorcing parents, yet there are areas of online program content and instructional strategies that can be improved. Program content that includes legal and court focused topics or modules, or that offer advice for families facing special circumstances such as domestic violence, could be enhanced. Additionally, most of the instructional strategies were passive. With this research, recommendations were made for improving program content and instructional strategies for online divorce education programs.     

Spatial displacement and diffusion of benefits among geographically focused policing initiatives: a meta-analytical review

Objectives  

To undertake a systematic review of the extent to which geographically focused policing initiatives appear to displace crime (simply relocate it to other places) or diffuse benefits (lead to reductions elsewhere).     

Factors Predicting Relationship Satisfaction,Investment, and Commitment When Women Report High Prevalence of Psychological Abuse

Relationship satisfaction, investment, and commitment in women experiencing extensive psychological abuse were examined to determine predictive factors. Participants were the top quartile of a national sample of women in conflictual relationships (N = 81) experiencing psychological maltreatment. Relationship satisfaction, investment, and commitment were each used as criterion variables with conceptually related factors as the predictors (e.g., reactions to the psychological abuse; mental health indicators; personality variables; perceived harm; problematic relationship schemas; response styles; demographics). These relationship markers were differentially predicted within this group of women. Three independent clusters of women, based on patterns of satisfaction, investment, and commitment scores, were compared regarding physical abuse, reactions to psychological abuse, ratings of perceived harm, endorsement of relationship schemas, psychological distress variables, and personality variables. The cluster of women reporting higher satisfaction, investment, and commitment in these seemingly aversive relationships frequently demonstrated differences from the other two clusters. Implications for clinical applications are discussed.     

Examining the relationship between childhood animal cruelty motives and recurrent adult violent crimes toward humans

Few researchers have studied the predictive ability of childhood animal cruelty motives as they are associated with later recurrent violence toward humans. Based on a sample of 180 inmates at one medium- and one maximum-security prison in a Southern state, the present study examines the relationship among several retrospectively identified motives (fun, out of anger, hate for the animal, and imitation) for childhood animal cruelty and the later commission of violent crimes (murder, rape, assault, and robbery) against humans. Almost two thirds of the inmates reported engaging in childhood animal cruelty for fun, whereas almost one fourth reported being motivated either out of anger or imitation. Only one fifth of the respondents reported they had committed acts of animal cruelty because they hated the animal. Regression analyses revealed that recurrent animal cruelty was the only statistically significant variable in the model. Respondents who had committed recurrent childhood animal cruelty were more likely to have had committed recurrent adult violence toward humans. None of the motives for committing childhood animal cruelty had any effect on later violence against humans.     

Associations between intimate partner violence and emotional distress among pregnant women in Durban, South Africa

Intimate partner violence (IPV) during pregnancy has been associated with multiple negative health outcomes including emotional distress during pregnancy. However, little is known about IPV during pregnancy and its association with emotional distress among South African women. The objectives of this study were to determine the prevalence of both emotional distress and IPV during pregnancy, to identify whether different exposures of violence were associated with emotional distress and to assess whether social support attenuated the relationship between IPV and emotional distress. Pregnant women enrolled in the South Africa HIV Antenatal and Posttest Support Study (SAHAPS) who completed the baseline survey were included in this cross sectional analysis. We used logistic regression models to explore bivariate and multivariate relationships between the proposed covariates and emotional distress. Nearly a quarter of women experienced some type of IPV during the current pregnancy, with psychological violence being the most prevalent. The odds of emotional distress was 1.41 times (95% CI: [1.26, 1.57]) higher for each additional episode of psychological violence and 2.01 times (95% CI: [1.16, 3.77]) higher for each additional episode of sexual violence during pregnancy, adjusting for other covariates. Physical violence was only marginally associated with increased odds of emotional distress. Finally, social support was marginally significant as a main effect but did not attenuate the relationship between IPV and emotional distress. The high prevalence of IPV among South African women and its association with emotional distress during pregnancy suggest that interventions that reduce violence during or prior to pregnancy are needed.     

Evidence of arteriosclerosis in cremated remains.

Severely burned or cremated human remains (i.e., cremains) are among the most challenging cases investigated by forensic pathologists, odontologists, and anthropologists. Exposure to extreme heat of long duration destroys all organic components of the body, leaving only the inorganic component of the skeleton. The numerous calcined osseous or dental fragments that remain after the cremation process rarely convey useful information to the investigator. In most cases, it is associated nonosseous artifacts that provide evidence of the decedent's identity. In a case investigated at the University of Florida's C. A. Pound Human Identification Laboratory, as well as in several cases examined during data collection for a research project, several fragments were identified as calcined plaque tubules from sclerotic blood vessels. These tubules provide direct evidence that the cremated individual had a variety of arteriosclerosis.     

Variations in the Recidivism of Treated and Nontreated Sexual Offenders in New Jersey: An Examination of Three Time Frames

This study examines the recidivism of sexual offenders in New Jersey at three different time intervals: three years, five years, and ten years after release from prison. The sample is comprised of sexual offenders released from the general prison population (untreated sample, n = 150) and the Adult Diagnostic and Treatment Center (ADTC) (treated sample, n = 150), a sex offender specific facility. The goals of this study were twofold: (1) to identify the recidivism rates of sexual offenders and to determine whether sexual offenders who receive treatment demonstrate lower levels of recidivism and (2) to examine whether differences in recidivism exist among the varying time frames and offender subtypes. The results indicate that treated sex offenders maintained decreased nonsexual recidivism rates. Additionally, offenders who committed acts of rape and offenders followed up after six years had increased rates of recidivism.
