Substance Use as a Longitudinal Predictor of the Perpetration of Teen Dating Violence

The prevention of teen dating violence is a major public health priority. However, the dearth of longitudinal studies makes it difficult to develop programs that effectively target salient risk factors. Using a school-based sample of ethnically diverse adolescents, this longitudinal study examined whether substance use (alcohol, marijuana, and hard drugs) and exposure to parental violence predicted the perpetration of physical dating violence over time. 1,042 9th and 10th grade high schools students were recruited and assessed in the spring of 2010, and 93 % of the original sample completed the 1-year follow-up in the spring of 2011. Participants who had begun dating at the initial assessment and who self-identified as African American (n = 263; 32 %), Caucasian (n = 272; 33 %), or Hispanic (n = 293; 35 %) were included in the current analyses (n = 828; 55 % female). Slightly more than half of the adolescents who perpetrated dating violence at baseline reported past year dating violence at follow-up, relative to only 11 % of adolescents who did not report perpetrating dating violence at baseline. Structural equation modeling revealed that the use of alcohol and hard drugs at baseline predicted the future perpetration of physical dating violence, even after accounting for the effects of baseline dating violence and exposure to interparental violence. Despite differences in the prevalence of key variables between males and females, the longitudinal associations did not vary by gender. With respect to race, exposure to mother-to-father violence predicted the perpetration of dating violence among Caucasian adolescents. Findings from the current study indicate that targeting substance use, and potentially youth from violent households, may be viable approaches to preventing the perpetration of teen dating violence.     

Effects of Institutional Reforms on Women's Representation in Colombia, 1960–2014

Starting in the 1990s, reforms aimed at addressing the underrepresentation of women have been implemented in Colombia. However, research on the consequences of these reforms has been inconclusive. This article analyzes the influence of institutional variables on the proportion of nominated and elected women in Colombia between 1962 and 2014, at both the national and local levels of government, in three different institutional environments. Results confirm the influence of institutional change, indicating that decentralizing reforms and the introduction of the gender quota have had a positive impact on the proportion of women's candidacies and elections, but that the adoption of the open list negatively affected the percentage of elected women.     

Argentinian Myths: Semiotics and Cultural Identity

This paper offers a semiotic reading of certain aspects of Argentinian culture and identity. We will analize some of the fundamental myths that are held by tourist when they visit the city of Buenos Aires. Tourists assume the existence of an Argentinian identity and believe it can be found by doing certain things. However cultural identities are nowadays defined by a tension between the local and the global consumption.     

Identification of victims of the collapse of a mine tailing dam in Brumadinho

The collapse of the B1 Dam of VALE SA mining company in Brumadinho, Minas Gerais, Brazil was the largest humanitarian disaster and occupational accident in the country’s history, and it posed challenges regarding the management and identification of multiple victims. We evaluated the impact of the iron ore tailings on the victims’ bodies. We examined the scientific identification of the victims and the dynamics of the disaster over the 1st year after it occurred. We also determined the socio-demographic profiles of the victims. In this retrospective, cross-sectional study, we investigated the expert reports of the victims’ biological remains from 25 January 2019 to 25 January 2020. We analysed the socio-demographic data, identification methods, identification status, identification time, and necroscopic information. During the study period, 259 of 270 victims were identified, and 603 biological materials were analysed; among them, 86.2% were body parts and 13.8% were whole bodies. Of the total cases registered that year, 476 (78.9%) were submitted during the first 10 weeks after the disaster. Friction ridge analysis accounted for 67.9% of primary identifications and DNA analysis did so for 91.6% of re-identification cases. Body dismemberment was 3.4 times greater among mine workers than among community victims. Adult males accounted for the greatest number of victims (P < 0.001). Polytraumatic injury was the prevalent single cause of death. Necropsy examination revealed the occurrence of asphyxia in 7% of cases. The higher number of fatalities and greater dismemberment among employees than with community residents underlines the occupational dangers in the mining industry and clarifies the dynamics of the disaster. In the initial weeks after the dam collapsed, friction ridge analysis was the most appropriate method for identification. Subsequently, DNA analysis became the most-used technique for identification and re-identification owing to the great volume of body parts and decomposed biological tissue. Autopsy allowed diagnosis of the causes of death to be clarified according to the Brazilian criminal legal system.     

Decision Making in Delinquency Cases: The Role of Race and Juveniles' Admission/Denial of the Crime

Investigated how accused delinquents' admission/denial of their crimes affected adjudication and disposition decisions. An archival analysis of 2,043 adjudication decisions in 16 Georgia counties found that juveniles who admitted committing their crimes were treated more severely than juveniles who denied committing their crimes. Whites were more likely than Blacks to admit committing the crime, and, after controlling for this and other legal factors, race did not have a significant effect. In the second study, 67 judges, 53 probation officers, and 126 court service workers made adjudication and disposition decisions about three juveniles in an experimental simulation in which race of juvenile, length of prior record, and the juvenile's reaction to the crime (admitting or denying it) were systematically manipulated. Consistent with the archival study, juveniles who admitted committing their offense were treated more severely than juveniles who denied committing their offense. Possible reasons are discussed for why admitting a crime leads to more punishment.     

A cost comparison study of using global positioning system technology (electronic monitoring) in a medium secure forensic psychiatric service

‘Electronic Monitoring’ (EM) uses devices to monitor individuals’ whereabouts. In 2010, South London and Maudsley medium secure unit introduced EM to monitor individuals on leave. Analysis after two years revealed EM was associated with increased unescorted leave and reduced leave violation; however, comparative costs were not established. This study aims to compare costs of EM for patients on leave by comparing average total cost per patient with and without EM. Costs were compared before and after implementation of EM. Total cost of leave for each group was divided by number of patients to generate average total cost per patient. The average total cost per patient without EM was £1702; £1617 with EM. Although cost decreased, this was not statistically significant. The results showed no significant difference between average total costs per patient before and after EM. The finding of EM being cost-neutral is cautiously optimistic. Further trials are recommended.
