Forensic Application of Analytical Mechanics in Fatal Fall From a Height

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.     

Child Sexual Abuse Perpetrated by Women: Case Series and Review of the Literature

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims’ severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims’ caregivers.     

Representational Altruism: The Wary Cooperator as Authoritative Decision Maker

What drives policymakers to put the interests of others above their own? If human nature is inherently selfish, it makes sense to institutionalize incentives that counter decision makers' temptations to use their positions to benefit themselves over others. A growing literature rooted in evolutionary theories of human behavior, however, suggests that humans, under certain circumstances, have inherent predispositions towards “representational altruism,” i.e., to make an authoritative decision to benefit another at one's own expense. Drawing on Hibbing and Alford's conception of the wary cooperator, a theoretical case is made for such behavioral expectations, which are confirmed in a series of original laboratory experiments.     

Exploring the Relationship Between Childhood Sexual Abuse and Adult Sexual Perpetration

Empirical findings indicate that many adult sexual offenders experienced sexual abuse during childhood. It has been suggested that characteristics of offenders' sexual perpetrating behaviors may resemble their own victimization experiences, although there has been minimal empirical investigation in this area. The purpose of the present study was to provide preliminary data on the relationship between childhood sexual abuse and characteristics of sexual offending behavior. A sample of adult male sexual offenders with histories of sexual abuse completed the Sexual Victimization Survey as well as a measure on their sexual offenses. Such characteristics as the nature of sexual activities, duration and frequency of experiences, and age and relationship of participants were examined. Results showed trends in the hypothesized direction and revealed a variety of similarities between childhood sexual abuse and adult sexual perpetration. Findings of this exploratory study suggest the importance of addressing the nature of victimization in the treatment of sexually abused boys and offenders with histories of sexual abuse.     

Histologic findings in the lung in sudden infant death

The lungs of 79 children who had died between the ages of 1 week and 2 years old were histologically examined. 59 of these children could be categorized as cases of Sudden Infant Death because of the history and postmortem findings. In the remaining 20 cases a definite cause of death could be established. This is the same collective on which the histological investigations of the lymphatic tissue has been carried out. Morphological changes which are typical for a virus pneumonia were found in a substantially higher frequency in the cases of Sudden Infant Death than in the control cases. The validity of these findings and their possible significance for the cause of death are discussed.     

Restriction fragment length polymorphism analysis of forensic science casework in the People's Republic of China.

Restriction fragment length polymorphism (RFLP) analysis for the purpose of individualization is now being used in casework in the People's Republic of China. This report describes the use of the multilocus minisatellite probe 33.15 to solve three cases, including two homicides and a rape. In the third case, fetal tissue was analyzed to prove that the alleged rapist was, in fact, the father. In each case, analysis of deoxyribonucleic acid (DNA) resulted in a positive match. The probability of chance association of the DNA fingerprint was calculated as 5.6 x 10(-12), which is similar to the figures reported in the literature.
