Fifty years on: against the stigmatising myths, taboos and traditions embedded within the Suicide Act 1961 (UK)

Although assisted suicide carries a maximum of 14 years imprisonment in England, courts and juries have historically demonstrated a reluctance to convict, most specifically in relation to those travelling abroad to accompany a terminally ill person seeking assisted dying. The possibility of prosecution is still present, however, and there have recently been a number of challenges to the law on assisted dying. During the consultation period of the Coroners and Justice Act 2009 (UK) an amendment was proposed that would have legalised, among other things, assisting suicide overseas. However, it was voted down by peers who believed it to be dangerously radical. In 2008 a multiple sclerosis sufferer requested a clear policy statement, should her partner help her to seek assisted dying abroad in the future. After her application was initially rejected, Mrs Purdy was granted leave to appeal and following a favourable ruling by the House of Lords in 2009, the Director of Public Prosecutions clarified the law on assisted suicide, introducing a Full Code Test which includes the consideration of "public interest factors". Although the new guidelines are not a direct threat to the 50-year-old Suicide Act 1961 (UK), it is clearly an historic development: the latest in a series of high-profile cases and debates which have taken place over the last decade. It is suggested that English law on assisted dying continues to rely on a range of inappropriate concepts, taboos and superstitions, and it is from this perspective that the implications for future legislative reform are addressed.     

A method for studying knife tool marks on bone

The characteristics of knife tool marks retained on hard tissues can be used to outline the shape and angle of a knife. The purpose of this study was to describe such marks on bone tissues that had been chopped with knives. A chopping stage with a gravity accelerator and a fixed bone platform was designed to reconstruct the chopping action. A digital microscope was also used to measure the knife angle (θ) and retained V-shape tool mark angle (ψ) in a pig skull. The κ value (elasticity coefficient; θ/ψ) was derived and recorded after the knife angle (θ) and the accompanied velocity were compared with the proportional impulsive force of the knife and ψ on the bone. The constant impulsive force revealed a correlation between the V-shape tool mark angle (ψ) and the elasticity coefficient (κ). These results describe the tool marks--crucial in the medicolegal investigation--of a knife on hard tissues.     

Effects of an Alibi Witness’s Relationship to the Defendant on Mock Jurors’ Judgments

Two studies tested the impact of an alibi witness’s relationship to a defendant on the perceived credibility of that witness. In the first study, 291 mock jurors estimated the frequency with which individuals would invent alibis, the frequency they themselves would do so, and the frequency of interpersonal contact among individuals of varying relationships. The degree of relationship between an alibi witness and a defendant remained a predictor of witness credibility when contact frequency was controlled. In the second study, 512 mock jurors were randomly assigned to case scenarios. Skepticism toward witnesses who are biologically or affinally related to a defendant was greater than skepticism toward a socially linked witness. Both studies supported predications from kinship theory and reciprocal altruism.     

Share the Wealth: Redistribution Can Increase Economic Efficiency

People frequently face uncertain income and the threat of loss can inhibit economic investments. Government redistribution can insure citizens against economic losses, but its effect on people’s investment decisions depends on how they react to redistributive rules. We apply methods from experimental economics to study how a redistributive institution affects people’s investment decisions. Experiment 1 tests whether redistribution can increase economic efficiency when people face risk problems—investment opportunities that are profitable on average but could result in a loss. In a between-subject design, participants decide whether to make a risky investment either individually or under an institution that redistributes earnings equally among four group members. We find greater investment and profits when participants are required to share their earnings. In Experiment 2, we examine free-riding by comparing an institution that allows non-investors to exploit investors to an assortment institution that matches investors with investors. We find that vulnerability to free-riding suppresses investment, whereas an assortment mechanism increases investment by preventing free-riding and thereby facilitating risk pooling.     

Female Overweight and Obesity in Adolescence: Developmental Trends and Ethnic Differences in Prevalence, Incidence, and Remission

Despite substantial increases in the prevalence of adolescent overweight and obesity documented in recent decades, few studies have prospectively tracked their development during the entire adolescent period. The aims of this study were to characterize developmental trends in prevalence, incidence, and remission of overweight and obesity using annual data collected from ages 12 to 19 for 496 adolescent females. Ethnic differences between African American (n = 37), Latina (n = 96), and European American (n = 348) adolescents were also compared. The prevalence of overweight decreased slightly across adolescence and remission rates exceeded incidence (onset). Obesity was more chronic, with increasing incidence accompanied by decreasing remission rates. Middle through late adolescence was the period of greatest risk for the transition from overweight to obesity. African American and Latina females had higher overweight and obesity prevalence than European American females throughout adolescence. Differences in prevalence were driven by higher onset rates for African American and Latina females, whereas remission rates were comparable across ethnic groups. Results suggest that adolescence is not a high-risk period for onset of obesity for European American adolescent females, but is for African American and Latina adolescent females.
