The application of anodic stripping voltammetry to forensic science. II. Anodic stripping voltammetric analysis of gunshot residues

Non-destructive analysis of gunshot residues on hands was studied by anodic stripping voltammetry using a low-cost home-constructed polarograph. The washing solution was 0.5 M HCl. Antimony was first analyzed in 4 M HCl solution; and zinc, lead and copper were then simultaneously analyzed in 0.2 M acetate buffer (pH 5.9 ± 0.1).     

Enhancing Witness Memory with Focused Meditation and Eye-Closure: Assessing the Effects of Misinformation

Despite the decline in popularity of hypnosis as an investigative interviewing technique, this paper builds on previous research showing that some of the techniques employed in traditional hypnotic interviewing may still be useful in the development of simple, brief memory facilitation procedures for use by the police. Three experiments are described that investigate the effects of a short Focused Meditation with eye-closure technique in situations where participants are presented with misleading information. In the first study, which utilized a standard misinformation paradigm, a significant memory facilitation effect was shown with Focused Meditation, though the effect was not significant for eye-closure alone. There were no increases in errors when the Meditation and eye-closure procedures were used alone or in combination. The second experiment showed that a combined Focused Meditation with eye-closure technique reduced misinformation effects associated with fictitious events, and a third showed that the same technique reduced interrogative suggestibility effects as measured by the Gudjonsson Suggestibility Scale, whilst facilitating free recall memory. It is concluded that a Focused Meditation with eye-closure technique may potentially have applications in the field where brief alternatives to the Cognitive Interview are required.     

Distribution of Venlafaxine,O‐desmethylvenlafaxine,and O‐desmethylvenlafaxine to Venlafaxine Ratio in Postmortem Human Brain Tissue

Venlafaxine (VEN) and its metabolite O‐desmethylvenlafaxine (ODV) inhibit reuptake of serotonin and norepinephrine. This study examines whether VEN is differentially distributed in postmortem brain and examines relationships between brain and femoral blood concentrations from donors prescribed VEN for treatment of depression. Using high‐pressure liquid chromatography‐ultraviolet detection, VEN and ODV concentrations were measured in temporal, occipital, and cerebellar cortex of six postmortem brains. The ODV/VEN ratio was calculated as a relative measure of drug metabolism within each region where higher ratios indicated a greater conversion of VEN to ODV. Compared to the other regions examined, the cerebellum showed decreased VEN (p = 0.056), ODV (p = 0.006), and ODV/VEN (p = 0.027) ratios. In parts per million, VEN was higher in temporal and occipital cortex, but not cerebellum, as compared to femoral blood concentration. These observations suggest that VEN and ODV are differentially distributed in the brain, and metabolism of VEN to ODV may vary across brain regions.     

The Emergence of a New Party in the Italian Party System: Rise and Fortunes of the Five Star Movement

This article examines the fortunes of the recently created Five Star Movement, a party that at its first general election in February 2013 became the most voted for party in Italy. It explains the success of this new party through citizens’ demands, patterns of party competition and institutional rules. Building on the interplay between popular demands and party supply, the study examines the overall political stance of this party and how it fits the policy priorities of citizens. By comparing it with other parties, the article investigates how the Five Star Movement distinguished itself from its competitors. Finally, the article examines how the electoral system has limited its emergence.     

Making Choices: Adoption Seekers’ Preferences and Available Children with Special Needs

Most children available from public adoption agencies are children with special needs, such as disabilities. This pilot study on the child profile preferences of 5830 adults registered with province-wide adoption agency found that those who were most open to considering children with special needs had been formally seeking to adopt for some time and had completed government-required SAFE assessments and training. Most preferred younger children, and half would consider sibling groups. Between 43% to 60% indicated willingness to consider adopting children with degrees of learning disabilities, emotional behavioral disorders, and physical disabilities, although the willing proportion decreased as the level of each disability's specified impact progressed from “mild” to “moderate” to “severe.” Most preferred, among 20 categories of available children's possible exposures and health diagnoses, were past abuse exposures versus diagnosed disabilities or enduring conditions. Possible explanations for these findings and their implications are explored and ideas for further research proposed.     

Weight-Related Teasing in the School Environment: Associations with Psychosocial Health and Weight Control Practices Among Adolescent Boys and Girls

Weight-related teasing has been found to be associated with low self-esteem, depressive symptoms, body dissatisfaction, and weight control behaviors in adolescents. While research has typically examined weight-related teasing directed towards the individual, little is known about weight-related teasing at the school level. This study aimed to determine the association between the school-level prevalence of weight-related teasing and psychosocial factors, body dissatisfaction and weight control behaviors in adolescents. Adolescents (N = 2,793; 53.2 % female) attending 20 US public middle and high schools were surveyed as part of the Eating and Activity in Teens (EAT) 2010 study. Generalized estimating equations were used to estimate the association between school-level weight-related teasing and health variables, controlling for individual-level weight-related teasing, clustering of individuals within schools, and relevant covariates. A greater school-level prevalence of weight-related teasing was associated with lower self-esteem and greater body fat dissatisfaction in girls, and greater depressive symptoms in boys, over and above individual-level weight-related teasing. Dieting was associated with the school-level prevalence of weight-related teasing in analysis adjusted for covariates in girls, but not following adjustment for individual-level weight-related teasing. Unhealthy weight control behaviors, extreme weight control behaviors, and muscle-enhancing behaviors were not associated with the school-level prevalence of weight-related teasing in girls or boys. Findings from the current study, in conjunction with previous findings showing associations between weight-related teasing, psychological concerns, and weight control behaviors, highlight the importance of implementing strategies to decrease weight-related teasing in schools.     

Inhabiting Mourning: Spectral Figures in Cases of Extrajudicial Executions (False Positives) in Colombia

In this article we analyse various forms of emotional management of mourning in the experiences of six female relatives of victims of extrajudicial executions in Colombia. Referencing the concept of the ‘spectral’, we discuss the ways in which family members establish ways of living with mourning that emphasise the impossibility of achieving closure, and explore the ways in which they keep the wounds of their suffering open as a means of organising themselves politically, in pursuit of justice. The article suggests an alternative to a teleology of closure, suggesting that, in contexts of impunity such as the one prevailing in Colombia, mourning becomes a scenario of habitability.
