Morphometrics of the hyoid bone for human sex determination from digital photographs

The identification of unknown remains is very important. When unknown remains are found, anthropologists first determine their sex and age. The sex of most skeletons is determined by their shape. In the hyoid bone, the shape is sex related, so it can be used forensically to determine the sex. This study focused on sex-based morphometry of the hyoid bone in Koreans using digital photographs. Hyoid bones from 52 males and 33 females were examined. For each subject, we took 34 measurements from photographs using a computer program, and the data were analyzed statistically using SPSS 11.0. Twenty-one of 34 measurements had significant sex differences (p<0.05). The discriminant functions based on three measurements (X(1)-X(3)) were as follows: The accuracy of discriminant functions is 88.2% in both groups, so these can be used to distinguish males from females in a statistically significant manner.     

Chaos in The Courtroom Reconsidered: Emotional Bias and Juror Nullification

A widespread presumption in the law is that giving jurors nullification instructions would result in "chaos"-jurors guided not by law but by their emotions and personal biases. We propose a model of juror nullification that posits an interaction between the nature of the trial (viz. whether the fairness of the law is at issue), nullification instructions, and emotional biases on juror decision-making. Mock jurors considered a trial online which varied the presence a nullification instructions, whether the trial raised issues of the law's fairness (murder for profit vs. euthanasia), and emotionally biasing information (that affected jurors' liking for the victim). Only when jurors were in receipt of nullification instructions in a nullification-relevant trial were they sensitive to emotionally biasing information. Emotional biases did not affect evidence processing but did affect emotional reactions and verdicts, providing the strongest support to date for the chaos theory.     

Drug and chemical related deaths: incidence in the State of Maryland--1975 to 1980

The incidence of drug and chemical related deaths was studied over a six-year period in the State of Maryland. Deaths were classified into the following categories: alcohol, carbon monoxide (CO), single drugs, multiple drugs, and narcotism. The last three categories were further subdivided as to the specific drugs or chemicals involved. Over the six-year period the number of alcohol and CO deaths remained steady, the number of barbiturate and propoxyphene deaths declined, while the number of tricyclic antidepressant drug deaths increased.     

Possibilities of the positive following violence and trauma: informing the coming decade of research

The effects of trauma and violence may be better understood by taking a broader perspective that includes resilience and recovery as well as damage and symptomatology. Based on this broader view, this article describes three interrelated, cutting-edge trends in mental health research: (a) the positive psychology movement, (b) the recognition of the role of spirituality and religion in health and well-being, and (c) stress-related growth. The integration of these trends into mainstream studies of trauma and violence will provide a counterbalance to the predominant orientation of victimization and pathology currently evidenced in the literature. All three have important implications for survivors of violence and trauma.     

An analysis of Korean homicide crime-scene actions

Recent studies have focused on how different styles of homicides will be reflected in the different types of behaviors committed by offenders at a crime scene. It is suggested that these different types of behaviors best be understood using two frameworks, expressive/instrumental aggression and planned/unplanned violence, to analyze the way the offender acts at the crime scene. Multidimensional analysis is carried out on the crime-scene actions of 70 Korean homicides. The proposed frameworks are found to be a useful way of classifying homicide offenses, assigning 80% of homicides to a dominant theme. Results also indicate that behavioral differences can be related to the differences in the offender-victim relationship. Finally, implications and suggestions for future research are discussed.
