Barriers and Supports to Dating Violence Communication between Latina Adolescents and Their Mothers: A Qualitative Analysis

Few Latinx parents and adolescents talk with one another about dating violence, yet communication with parents could help adolescents make better decisions about dating relationships. Seventeen Latina adolescents (15–17 years old) and their mothers living in Washington D.C and central Virginia participated in semi-structured interviews to explore their perceptions of dating violence behavior and communication with parents about dating violence. Interviews were digitally recorded, transcribed, and coded for emergent themes using a grounded theory approach. Seven themes emerged and were grouped into three domains: (a) Parental Messages about Problems in Dating Relationships; (b) Barriers and Supports for Parent-Adolescent Communication about Dating Problems; and, (c) Cultural Values and Differences. The results of this study can be used to inform future work focused on improving parent-adolescent communication about dating violence and to enhance healthy adolescent Latina dating decisions.

A possible source of reference DNA from archived treated adhesive lifters

During the course of a double murder trial, it became apparent that the two adhesive lifters from the two cadavers had been mislabeled before being presented in court. The question was raised whether DNA testing from the biological material remaining attached to the lifters could resolve this mix-up. In fatal shooting cases where a bullet has been fired through a body surface, an adhesive lifter is applied directly to the entrance wound. The total nitrite residues, as well as biological material surrounding the wound (blood, hair, tissue) are transferred to the adhesive lifter. The nitrite residues are used for estimating firing distance. In a worst-case scenario, the biological material on the lifter may be the only remaining reference material from a victim. In this paper, we examined whether the biological material retrieved from adhesive lifters could be used for DNA typing after the lifters had been treated for GSR pattern. In as much as the biological material found on the lifters can be typed and profiled following physical and chemical treatment, we submit that archived adhesive lifters can be used as a future source of reference DNA from cadavers where no other sample is available.     

Tax Amnesty as Price-Discriminating Behavior by a Monopolistic Government

We consider perfectly anticipated periodic tax amnesties characterized by a tax rate lower than the ordinary one and used by a monopolistic government to maximize net fiscal revenue. We model tax amnesties as a form of intertemporal price discrimination. It turns out that, under certain conditions, discrimination secures the highest net revenue, as amnesties incorporate a self-selection mechanism that renders it possible to collect additional payments from tax evaders, without inducing honest taxpayers to join them. Optimal timing for granting tax amnesties may be calculated, but problems of time inconsistency in government behavior may arise.     

'The story of Abraham,Isaac and Jacob" or "am I my brother's keeper?"

Presented is a case report of a violent sexual assault where the DNA profile obtained from an item of evidence was compared to a suspect's profile. The profiles did not match, but the sharing of such a large number of alleles raised the suspicion that perhaps the real perpetrator was a blood relative of the suspect. The investigators requested a sample from the suspect's brother, and a match was defined. In an era of technological breakthroughs in the field of forensic DNA analysis, the importance of the scientist's attention to the evidence presented in each case is stressed.     

A Y-chromosome STR marker should be added to commercial multiplex STR kits

Abstract:  Autosomal short tandem repeat (STR) analysis has become highly relevant in the identification of victims from mass disasters and terrorist attacks. In such events, gender misidentification can be of grave consequences, yet the list reporting amelogenin amplification failure using STR multiplex kits continues to grow. Presented here are three such examples. In the first case, we present two male suspects who demonstrated amelogenin Y-deficient results using two commercial kit procedures. The presence of their Y chromosomes was proven by obtaining a Y-haplotype. The second case demonstrated a profile from a third male suspect where only the Y homolog of the XY pair was amplified. In events such as mass disasters or terrorist attacks, timely and reliable high throughput DNA typing results are essential. As the number of reported cases of amplification failure at the amelogenin gene continues to grow, we suggest that the incorporation of a better gender identification tool in commercial kits is crucial.     

Human height estimation from highly distorted surveillance image

Video surveillance camera (VSC) is an important source of information during investigations especially if used as a tool for the extraction of verified and reliable forensic measurements. In this study, some aspects of human height extraction from VSC video frames are analyzed with the aim of identifying and mitigating error sources that can strongly affect the measurement. More specifically, those introduced by lens distortion are present in wide-field-of-view lens such as VSCs. A weak model, which is not able to properly describe and correct the lens distortion, could introduce systematic errors. This study focuses on the aspect of camera calibration to verify human height extraction by Amped FIVE software, which is adopted by the Forensic science laboratories of Carabinieri Force (RaCIS), Italy. A stable and reliable approach of camera calibration is needed since investigators have to deal with different cameras while inspecting the crime scene. The performance of the software in correcting distorted images is compared with a technique of single view self-calibration. Both approaches were applied to several frames acquired by a fish-eye camera and then measuring the height of five different people. Moreover, two actual cases, both characterized by common low-resolution and distorted images, were also analyzed. The height of four known persons was measured and used as reference value for validation. Results show no significant difference between the two calibration approaches working with fish-eye camera in test field, while evidence of differences was found in the measurement on the actual cases.     

Perspectives,practices and prospects of public affairs in Central and Eastern Europe: a lobbying future anchored in an institutional context

‘Public Affairs’ is not a term most people in Central and Eastern Europe (CEE) will recognise and associate with interest representation and lobbying as ways of linking business, society and government. The term may be seen as a euphemism for corruption-inspired ‘lobbying’, an artificial and confusing umbrella term or a public relations creation. It is a term in transition for a subject in transition in a part of Europe in transition. Even as part of the European Union, CEE is still different, in transition, finding its own feet like a phoenix arising from the ashes of 50 years of communism, but slowly, in bursts, réculer pour mieux sauter and very different from country to country. Which are the features and values of the 50 years of communism that will disappear, fast more slowly, which ones will linger on? What are the institutions in CEE countries that public affairs will have to deal with, and what is the view on transparency and transparency regulation in CEE? To add understanding, values, cultural differences, institutional context and other factors affecting the public affairs environment are examined. Copyright © 2014 John Wiley & Sons, Ltd.
