Gasoline on hands: preliminary study on collection and persistence

The identification of an arsonist remains one of the most difficult challenges a fire investigation has to face. Seeking and detection of traces of gasoline could provide a valuable information to link a suspect with an arson scene where gasoline was used to set-up the fire. In this perspective, a first study was undertaken to evaluate a simple, fast and efficient method for collecting gasoline from hands, and to assess its persistence over time. Four collection means were tested: PVC, PE and Latex gloves, as well as humidified filter paper. A statistical assessment of the results indicates that Latex and PVC gloves worn for about 20 min, as well as paper filter rubbed on hands, allow an efficient collection of gasoline applied to hands. Due to ease of manipulation and to a reduced amount of volatile compounds detected from the matrix, PVC gloves were selected for the second set of experiments. The evaluation of the persistence of gasoline on hands was then carried out using two initial quantities (500 and 1000 microl). Collection was made with PVC gloves after 0, 30 min, 1, 2 and 4h, on different volunteers. The results show a common tendency of massive evaporation of gasoline during the first 30 min: a continued but non-linear decrease was observed along different time intervals. The results of this preliminary study are in agreement with other previous researches conducted on the detection of flammable liquid residues on clothes, shoes and skin.     

Who cares about human rights? Public opinion about human rights foreign policy

Literature on foreign aid and human rights often presupposes that constituents favor using foreign policy to promote human rights abroad and lead elected policymakers to pursue such policies to retain electoral support. This assumption, although frequently asserted, has not been empirically evaluated. And there are reasons to be skeptical about whether public opinion supports human rights foreign policy compared to other policy objectives. This article explores US public opinion about human rights, by asking two questions: Does the public think human rights should factor in foreign aid decisions and does the context—the strategic or economic relationship between the donor and recipient—affect this? This article uses results from a nationwide experimental survey to evaluate these questions. I find that the majority of respondents support cutting aid to punish human rights violators and that this depends minimally on the importance of the recipient.

Quantitative Analysis of the Morphological Changes of the Pubic Symphyseal Face and the Auricular Surface and Implications for Age at Death Estimation

Age estimation methods are often based on the age‐related morphological changes of the auricular surface and the pubic bone. In this study, a mathematical approach to quantify these changes has been tested analyzing the curvature variation on 3D models from CT and laser scans. The sample consisted of the 24 Suchey–Brooks (SB) pubic bone casts, 19 auricular surfaces from the Buckberry and Chamberlain (BC) “recording kit” and 98 pelvic bones from the Terry Collection (Smithsonian Institution). Strong and moderate correlations between phases and curvature were found in SB casts (ρ 0.60–0.93) and BC “recording kit” (ρ 0.47–0.75), moderate and weak correlations in the Terry Collection bones (pubic bones: ρ 0.29–0.51, auricular surfaces: ρ 0.33–0.50) but associated with large individual variability and overlap of curvature values between adjacent decades. The new procedure, requiring no expert judgment from the operator, achieved similar correlations that can be found in the classic methods.     

Association for Conflict Resolution Guidelines for Eldercaring Coordinators

On November 6, 2014, the AFCC Board of Directors endorsed the Association for Conflict Resolution (ACR) Guidelines for Eldercaring Coordination, including ethical principles for Eldercaring Coordinators, training protocols, and court pilot project template. The collaboration between Task Forces created by ACR and the Florida Chapter of AFCC, composed of twenty U.S./Canadian and twenty Florida‐wide organizations, produced both an overarching guide to assist in the development of programs and a more detailed model addressing state/province‐specific needs and characteristics. Eldercaring coordination is a dispute resolution option specifically for high‐conflict cases involving the care, needs, and safety of elders.

Key Points for the Family Court Community:
• There are currently no dispute resolution options for parties involved in high‐conflict cases regarding the care, needs, and safety of an elder.
• The ACR Guidelines for Eldercaring Coordination address the discrepancies between dispute resolution options available for parents in conflict regarding their minor children and mature families with unresolved concerns about the care, needs, and safety of an elder.
• The ACR Guidelines for Eldercaring Coordination provide information regarding the ethical practice of eldercaring coordination including a specific definition, recommended qualifications, ethical practices, grievance procedures, training protocols, and a court pilot project template.
• The practice of eldercaring coordination will address the influx of court cases expected as baby boomers continue to age, reducing delays in court hearings, as parties will have the opportunity to resolve their concerns without continuous court attention.
• As of June 2015, five states began Pilot Projects on Eldercaring Coordination, which will be studied by an independent research group to enhance the progress of the process and to develop the best practices for initiating the programs elsewhere.

     

Exploring the criminal histories of stranger sexual killers

Although sexual homicide is receiving increasing research attention, few studies have examined the criminal histories of sexual killers in any detail. This study examined the criminal histories of 81 British stranger sexual killers to determine whether they were generalist, specialists or both and whether their criminal histories reflected violent, sexual, marginality and over control pathways. Results found most stranger sexual killers were generalist offenders and sexual homicide was part of a varied criminal repertoire and non-sexual crimes predominate. This ‘antisocial orientation’ means future offending may not be limited to sexual violence. Criminal histories reflected the violent, sexual, marginality and over control pathways, but offenders in the violent pathway were more criminally orientated. The clinical and investigative implications of these findings were considered as they suggest knowledge of the criminal histories of stranger sexual killers is an important consideration for criminal justice professionals.     

The association of distress and denial of responsibility with maladaptive personality traits and self‐esteem in offenders

This study aimed to examine the relationship of offenders' distress and responsibility with maladaptive personality traits, self‐esteem, and offence‐type. It also further validated the Distress and Responsibility Scale (DRS; Xuereb et al., 2009a, Pers. Individ. Diff., 46, 465). A new sub‐scale measuring social desirability was included and assessed in the DRS. Maladaptive personality traits and self‐esteem were measured in relation to the following predictions: (1) that maladaptive personality traits would positively correlate with distress (2) that self‐esteem would negatively correlate with distress and acknowledging responsibility. The sample was 405 male sexual, violent, and general offenders from a UK prison. Participants anonymously completed a questionnaire measuring the variables under investigation. The factor‐structure of the DRS was confirmed via Confirmatory Factor Analysis after minor changes. No significant differences in distress and denial of responsibility were found between sexual, violent, and general offenders. Maladaptive personality traits positively correlated with chronic and offence‐related distress, chronic self‐blame, and minimization of offence harm. Chronic and offence‐related distress and responsibility negatively related to self‐esteem. The study concludes that the DRS has reached stability, and that the social desirability scale increases the measure's validity. Assessment and treatment for offence‐related distress and denial of responsibility should be offered to all offence groups. Offenders would benefit from structured interventions to manage difficulties associated with maladaptive personality traits, including chronic distress and self‐blame. Finally, it was concluded that self‐esteem might serve a self‐defensive function for offenders.
