Incestuous paternity detected by STR-typing of chorionic villi isolated from archival formalin-fixed paraffin-embedded abortion material using laser microdissection

Microscopic examination of a blood clot expelled by a physically and mentally disabled woman taken to the emergency room because of genital bleeding revealed the presence of chorionic villi encircled by decidua, hemorrhage, and necrosis. In order to identify the father of the product of conception, sections of formalin-fixed, paraffin-embedded abortion material were subjected to laser microdissection: DNA extraction from chorionic villi selectively isolated from the surrounding tissues allowed successful STR-typing of fetal cells, which was otherwise prevented by excess maternal DNA. The large number of homozygous genotypes in the fetal profile suggested incestuous paternity. Analysis of reference DNA samples from male relatives excluded the woman's father, paternal grandfather, and maternal grandfather, whereas the obligate paternal alleles of the fetus were constantly present in the genotypes of the woman's brother, clearly demonstrating brother-sister incest (probability of paternity > 99.99999%).     

Amino acid alanine reactivity with the fingerprint reagent ninhydrin. A detailed ab initio computational study

Ninhydrin is one of the most widely used reagents for chemical development of fingerprints on porous surfaces. The detection is based on the reaction of ninhydrin with a monoacidic component of the fingerprint to form an intensively colored compound named Ruhemann's Purple. A computational study of the mechanisms and reaction energetics of the formation of Ruhemann's Purple from ninhydrin and alanine is presented. Such a study is significant from a forensic science point of view because of the strong interest in the forensic chemistry and law enforcement communities in developing alternatives to the current generation of ninhydrin like chemicals for the detection and development of latent fingerprints. Information about the mechanism of reaction between ninhydrin and amino acids can ultimately help to design compounds with stronger chromo-fluorogenic properties in aid of detecting fingerprints at crime scenes. The three most accepted mechanisms of formation have been considered using ab initio quantum mechanical calculations. At relatively high temperature ( approximately 100 degrees C) all three mechanisms are energetically feasible. However since it is recommended that forensic analyses be performed at room temperature, a revised mechanism is proposed for the formation of Ruhemann's Purple under this condition.     

Gender disparity in criminal offenses among persons of high IQ

Criminologists have largely neglected deviance among those with high IQs. This work uses Towers's (1988) concept of conventional genius to analyze how deviant behavior varies by gender among genius offenders. Like Bisi (2002), the authors expect female patterns of deviance to be lower than that for males even within this genius sample. Their work finds that male geniuses are significantly more likely to self-report ever having committed violent felonies. Among the authors' conventional genius sample of university students, gender differences in nonviolent felonies, misdemeanor offenses, and unethical behaviors are not significantly different between the female and male respondents.     

Prior Experiences as Temporal Frames of Reference in Social Justice: The Influence of Previous Fairness Experiences on Reactions to New and Old Supervisors

This paper focuses on the psychology of social change and social justice. Specifically, we focus on subordinates’ reactions to new and old supervisors, and we argue that in evaluating these different types of supervisors, subordinates may rely on prior fair or unfair experiences as temporal frames of reference. We further propose that a result of these frames of reference may be that previous fairness experiences have a bigger impact on subordinates’ reactions to subsequent neutral communications when an old rather than when a new supervisor is the source of that communication. Findings of two empirical studies indeed show that subordinates who had had fair experiences with a particular supervisor reacted more positively toward subsequent neutral messages when the communication was coming from the old supervisor rather than from the new supervisor. Subordinates who had had unfair experiences, however, reacted more negatively toward the communication when the source was the old rather than the new supervisor. Some evidence was also found for contrast effects such that people who react to a new supervisor may react more positively with the neutral demand from this authority figure when they have earlier experienced unfair as opposed to fair treatment by a different supervisory agent. These findings were obtained on subordinates’ satisfaction with the supervisors’ communication and their acceptance of the supervisor. Finally, we discuss the implications for the psychology of social change and social justice.     

Working women making it work: intimate partner violence, employment, and workplace support

Partner violence may have significant consequences on women's employment, yet limited information is available about how women cope on the job with perpetrators' tactics and the consequences of her coping methods on employment status. This article investigates whether there is an association between workplace disclosure of victimization and current employment status; and whether there is an association between receiving workplace support and current employment status among women who disclosed victimization circumstances to someone at work. Using a sample of partner victimized women who were employed within the past year (N = 485), cross-tabulation and ANOVA procedures were conducted to examine the differences between currently employed and unemployed women. Binary logistic regressions were conducted to examine whether disclosure and receiving workplace support were significantly associated with current employment. Results indicate that disclosure and workplace support are associated with employment. Implications for clinical practice, workplace policies, and future research are discussed.     

Partner stalking and implications for women's employment

In general research suggests partner violence has a negative impact on women's employment. However, there has been limited examination of partner stalking and consequences for employment. The purpose of this study was to examine partner stalking and employment consequences among two samples of women. One sample was women who had obtained a protective order against a violent partner and had worked in the prior year (n = 482), about one half of these women were stalked by their violent partner and one half were not. The second study examined qualitative information from women recently stalked (n = 62) by a violent partner. Results from both studies suggest that women who were stalked by a violent partner were significantly more susceptible to on-the-job harassment and problems. Also, women reported that stalking by a partner interfered in their work through on-the-job harassment, work disruption, and job performance problems. Implications for policy and research are discussed.
