The juvenile death penalty and the Eighth Amendment

The present study investigated the Eighth Amendment tests of societal consensus and proportionality as applied to juvenile death penalties. A sample of former jurors (N=179) voted on whether to execute the defendant in a hypothetical case. Defendant's age (10, 15, 16, or 19) and level of remorse were varied. A large percentage of participants voted to execute the defendant in each condition, but the defendant's age and the participant's attitude toward juvenile culpability significantly predicted the likelihood of execution. Implications for the constitutionality of the juvenile death penalty and future research directions are discussed.     

Prevalence of spouse aggression in Hong Kong

The present study explored the extent of spouse aggression in Chinese families in Hong Kong. Subjects were 246 female and 136 male undergraduate students who reported on the various forms of interparental aggression and violence. About 75% of the subjects reported interparental verbal or symbolic aggression and 14% indicated the use of physical violence between parents. In general, compared to mothers, fathers engaged in more verbal aggression against their spouses. Mothers were as likely as fathers to use actual physical force toward their spouses. Interparental responses to family conflicts did not vary with children's gender except that female subjects observed that fathers reasoned less but engaged in more insulting, throwing, smashing, hitting, or kicking things than mothers.     

The Missing Child in Child Protection: The Constitutional Context of Child Maltreatment From Meyer to DeShaney

This paper employs DeShaney v Winnebago County (1989) as an illustration of how the law has lost sight of the interests of children in cases of child maltreatment. The historical constitutional context of child maltreatment – balancing state's interests and parental rights – is discussed. The opinions in DeShaney and two of the major criticisms of the majority's opinion – the action versus inaction dichotomy and the restrictive interpretation of the special relationship doctrine – are then considered. Legislatively created entitlements to protection are suggested as an avenue of relief for injured children which also necessitates a focus on the rights and interests of children.     

Detection and quantification of the age-related point mutation A189G in the human mitochondrial DNA

Mutation analysis in the mitochondrial DNA (mtDNA) control region is widely used in population genetic studies as well as in forensic medicine. Among the difficulties linked to the mtDNA analysis, one can find the detection of heteroplasmy, which can be inherited or somatic. Recently, age-related point mutation A189G was described in mtDNA and shown to accumulate with age in muscles. We carried out the detection of this 189 heteroplasmic point mutation using three technologies: automated DNA sequencing, Southern blot hybridization using a digoxigenin-labeled oligonucleotide probe, and peptide nucleic acid (PNA)/real-time PCR combined method on different biological samples. Our results give additional information on the increase in mutation frequency with age in muscle tissue and revealed that the PNA/real-time PCR is a largely more sensitive method than DNA sequencing for heteroplasmy detection. These investigations could be of interest in the detection and interpretation of mtDNA heteroplasmy in anthropological and forensic studies.     

Potential and pitfalls in establishing the provenance of Earth-related samples in forensic investigations

Earth scientists are often asked to establish or constrain the likely provenance of very small quantities of earth-related material as part of a forensic investigation. We tested the independent and collective interpretations of four experts with differing analytical skills in the prediction of sample provenance for three samples from different environmental settings. The methods used were X-ray diffraction, scanning electron microscopy, the assessment of pollen assemblages, and structural characterization of organic matter at the molecular level. Independent interpretations were less accurate than those where multiple techniques were combined. Collective interpretation was very effective in the assessment of provenance for two of the three sites where the mineralogy and plant communities were distinctive. At the other site, although the mineralogical analysis correctly identified the Triassic mudstone soil parent material, Carboniferous spores from domestic coal were initially interpreted as deriving directly from bedrock. Such an interpretation could be a common pitfall owing to anthropogenic redistribution of material such as coal.     

A prospective analysis of sexual assault perpetration: risk factors related to perpetrator characteristics

This study prospectively evaluated perpetrator risk factors for sexual assault perpetration, including peer influences, beliefs and attitudes about sexuality, alcohol use, and token resistance. Perpetration of sexual assault was evaluated at three time periods: pretest, 3-month follow-up, and 7-month follow-up. Retrospective and prospective analyses yielded differential predictors of sexually aggressive behavior. However, perpetration of sexual assault at any particular assessment period was a predictor of perpetration during the subsequent follow-up period. Furthermore, several variables that have previously been demonstrated in the literature to be related to the perpetration of sexual assault were not significant in regression analyses, indicating that these variables may be rendered insignificant when accounting for past perpetration in prospective analyses. These findings may have significant potential impact on development of sexual assault prevention programming with men.
