Mitochondrial DNA sequencing of cat hair: an informative forensic tool

Approximately 81.7 million cats are in 37.5 million U.S. households. Shed fur can be criminal evidence because of transfer to victims, suspects, and/or their belongings. To improve cat hairs as forensic evidence, the mtDNA control region from single hairs, with and without root tags, was sequenced. A dataset of a 402-bp control region segment from 174 random-bred cats representing four U.S. geographic areas was generated to determine the informativeness of the mtDNA region. Thirty-two mtDNA mitotypes were observed ranging in frequencies from 0.6-27%. Four common types occurred in all populations. Low heteroplasmy, 1.7%, was determined. Unique mitotypes were found in 18 individuals, 10.3% of the population studied. The calculated discrimination power implied that 8.3 of 10 randomly selected individuals can be excluded by this region. The genetic characteristics of the region and the generated dataset support the use of this cat mtDNA region in forensic applications.     

Identifying and classifying juvenile stalking behavior

Despite the growing research in the area of stalking, the focus has been on adults who engage in this behavior. Unfortunately, almost no studies investigate the prevalence of this behavior in adolescents. Two cases are presented demonstrating not only that stalking occurs during the period of adolescence, but also that there is a significant difference in the motivation underlying this behavior that can be classified similarly to that of adult stalkers. Further, a suggested classification based on these two cases as well as our experience with other juveniles who have exhibited stalking behaviors is proposed. The first case involves a narcissistic youth who also possesses psychopathic traits, while the second involves a lonely, severely socially awkward teen. Juvenile stalking is a societal problem that has not yet garnered the attention it deserves, and all systems that deal with juvenile delinquency (juvenile court, law enforcement, and mental health personnel) as well as the school system must be educated to the prevalence and severity of this yet-to-be-recognized problem.     

The WTO's Environmental Progress

The linkage between trade and the environment stands out asan important challenge in global economic governance. Over thepast decade, the WTO devoted considerable attention to thisissue and included it on the agenda of the Doha Round. In parallel,the jurisprudence on trade and the environment has experiencedsignificant advances. This study provides an overview of themain institutional changes at the WTO and of the developmentsin the jurisprudence most relevant to the interaction betweenthe environment and trade. Specifically, this study focuseson General Agreement on Tariffs and Trade (GATT) Article XXand takes note of many positive (and a few negative) featuresof the key Appellate Body decisions.     

Real-time polymerase chain reaction quantification of canine DNA

The accurate quantification of target DNA is an important step in the short tandem repeat analysis of forensic biological samples. By utilizing quantification data to control the amount of template DNA in the polymerase chain reaction (PCR), forensic scientists can optimize testing and minimize the consumption of limited samples. The ability to identify and quantify target DNA in mixed-species samples is crucial when it may be overwhelmed by nontarget DNA, as in cases of dog attack. We evaluated two quantitative real-time PCR assays for dynamic range, species specificity, and inhibition by humic acid. While both assays proved to be highly sensitive and discriminating, the Melanocortin-1 Receptor (MC1R) gene Taqman assay had the advantages of a shorter run time, greater efficiency, and safer reagents. In its application to forensic casework, the MC1R assay has been advantageous for quantifying dog DNA in a variety of mixed-species samples and facilitating the successful profiling of individual dogs.     

Self-Defense, Punishing Unjust Combatants and Justice in War

Some contemporary Just War theorists, like Jeff McMahan, have recently built upon an individual right of self-defense to articulate moral rules of war that are at odds with commonly accepted views. For instance, they argue that in principle combatants who fight on the unjust side ought to be liable to punishment on that basis alone. Also, they reject the conclusion that combatants fighting on both sides are morally equal. In this paper, I argue that these theorists overextend their self-defense analysis when it comes to the punishment of unjust combatants, and I show how in an important sense just and unjust combatants are morally equal. I contend that the individualistic and quid pro quo perspective of the self-defense analysis fails to consider properly how the international community, morally speaking, ought to treat combatants, and I set forth four elements of justice applicable to war, which, together, support the conclusion that in principle the international community should not take on the activity of punishing combatants solely for fighting on the unjust side.     

Predictors of sex offender treatment dropout: psychopathy,sex offender risk,and responsivity implications

Abstract

We examined sex offender treatment dropout predictors, in particular, the relationship of psychopathy and sex offender risk to treatment dropout in a sample of 154 federally incarcerated sex offenders treated in a high intensity sex offender treatment program. Demographic, criminal history, mental health and treatment-related data as well as data on risk assessment measures including the Static 99, Violence Risk Scale – Sexual Offender version (VRS-SO), and Psychopathy Checklist – Revised (PCL-R) were collected. Logistic regression and discriminant function analyses were used to identify predictors that made significant and unique contributions to dropout among all the variables under study. The Emotional facet of Factor 1 of the PCL-R and never being married were found to be the most salient predictors of treatment dropout and correctly identified about 70% of the cases. The implications of the findings for managing treatment dropout and for the treatment of psychopathic offenders are discussed.     

A New Method of Assessing Judicial Workload in Juvenile Dependency Cases

This article describes a new method for calculating judicial workload in dependency or child abuse and neglect cases. In contrast to traditional judicial workload methods, the method described herein produces estimates of judicial workload that take into account the complex role of the juvenile dependency court judge—a role that includes both on‐ and off‐the‐bench activities. The method provides workload estimates that give guidance to courts not only about the minimally sufficient judicial resources needed to accommodate current caseload needs, but also what level of judicial resources would be required to hold substantive dependency court hearings that comport with nationally recognized practice recommendations. The article reviews commonly used judicial workload methods, outlines the new method, and uses a pilot of the method as an example of how the method works in practice. Broader implications of this workload method are also discussed.     

Market coordination and the making of conventions: qualities,consumption and sustainability in the agro-food industry

Abstract

The coordination of activity across sites and spaces of production and consumption is a key concern for economic analysis. Joining a revival in the application of convention theory to agro-food scholarship, this paper considers complementary insights – related principally to ‘the economy of qualities’ – that animate different aspects of e/valuation, competition and alignment. These understandings are extended by more thoroughly acknowledging contemporary developments in consumption scholarship. The arguments are advanced through a case study of the orange juice market, linking its current high-carbon trajectory to the commercial and cultural significance of freshness. The analysis offers new insights into distributed processes of qualification as well as the mechanisms through which conventions are assembled and sustained. Finally, a more integrated approach to food production and consumption is outlined.
