An Investigation of Normal Urine with a Creatinine Concentration Under the Cutoff of 20 mg/dL for Specimen Validity Testing in a Toxicology Laboratory,

In clinical and forensic toxicology laboratories, one commonly used method for urine specimen validity testing is creatinine concentration. In this study, workplace guidelines are examined to determine their relevance to forensic and clinical toxicology samples. Specifically, it investigates the occurrence of urine creatinine concentrations under 20 mg/dL and notes potential issues with factors influencing creatinine concentration by utilizing a simple, novel method consisting of cation‐paring high‐pressure liquid chromatography in tandem with ultraviolet detection to determine the creatinine concentration in 3019 donors. Of the 4227 sample population in this study, 209 (4.94%) were below the cutoff value of 20 mg/dL for dilute urine. Because there are many factors that can influence the urinary creatinine concentration, samples that have creatinine under the 20 mg/dL cutoff do not always implicate sample adulteration.     

Trichophyton Mentagrophytes Perforates Hair of Adult Corpses in the Gaseous Period*

Abstract: Despite the substantial literature on mycology, there are still limited reports of the interaction between fungi and human hosts in the postmortem period. Thus, the main goal of this study was to investigate the in vitro perforation test using Trichophyton mentagrophytes on hair from adult corpses in the postmortem period (gaseous period). The protocol was carried out with positive (prepubescent children’s hair) and negative controls (healthy adult hair) as well. One strain of Trichophyton rubrum was also used as a negative perforation control. Perforations were found in all the hair samples from corpses and prepubescent children after 12–14 days exposure to T. mentagrophytes and were absent in the hair samples of healthy adults. Furthermore, hair perforation was not observed with T. rubrum. Our preliminary findings suggest the use of T. mentagrophytes as a potential marker of the death interval in forensic science.     

Comprehensive evaluation: a holistic approach to evaluating domestic violence offender programmes

This article argues that the focus on behavioural outcomes in evaluations of domestic violence offender programmes has been too narrow, and that a more holistic approach incorporating investigation of the psychological characteristics of offenders and treatment characteristics may be required to determine what works, for whom, and under what circumstances. To this end, one interpretation of a comprehensive evaluation framework is outlined. The article hypothesises the insights to be gained by assessing the contribution of several potential mediating variables of the treatment process in the evaluation of these programmes. These variables are the heterogeneity of treatment targets in the target population; motivation to change; programme integrity variables; and therapeutic factors. The article concludes that only by implementing theoretically informed, multifaceted evaluations will we move closer to understanding the process of successful rehabilitation.     

When transgressions become transparent: limiting family forms in assisted conception

This article explores the social processes through which ideas about the family become translated into regulation and practice in assisted conception. Drawing on social problems literature, it is suggested that claims are made (by regulators, practitioners and others) about the desirability of certain family types and that forms of regulation occur when families transgress, in particularly obvious ways, the boundaries of those definitions. The apparently disparate examples of lesbian access to donor insemination and donor anonymity are brought together to illustrate the argument. It is also suggested that much formal regulation and clinical practice is directed towards making such transgressions less transparent, thus protecting the practice of assisted conception from unwelcome scrutiny.     

Value orientations,life transitions,and desistance: Assessing competing perspectives

Laub and Sampson (2003) and Paternoster and Bushway (2009) offered opposing explanations of desistance from crime. Yet, extant research has failed to test the key theoretical differences that distinguish these perspectives: 1) the temporal ordering of internal changes in identity/values and life transitions and 2) the impact of values/life transitions on offending conditional on key predictors from the opposing theory (e.g., whether marriage contributes to desistance among individuals who already hold prosocial values). We assess competing claims using data from the Pathways to Desistance. We find that within-person changes in prosocial value orientations are significantly related to within-person changes in one's likelihood of entering into serious romantic relationships and becoming employed. Conversely, life transitions are unrelated to changes in one's values. The results derived from fixed-effects Poisson models indicate high or increasing prosocial value orientations help explain offending patterns among those who enter into serious romantic relationships/get employed and help explain changes in offending among those who do not experience structural “turning points.” Marriage/cohabitation is unrelated to within-person changes in offending, whereas the impact of employment has an inconsistent relationship. Theoretical and policy implications are discussed.     

SNP Miniplexes for Individual Identification of Random‐Bred Domestic Cats

Phenotypic and genotypic characteristics of the cat can be obtained from single nucleotide polymorphisms (SNPs) analyses of fur. This study developed miniplexes using SNPs with high discriminating power for random‐bred domestic cats, focusing on individual and phenotypic identification. Seventy‐eight SNPs were investigated using a multiplex PCR followed by a fluorescently labeled single base extension (SBE) technique (SNaPshot^®). The SNP miniplexes were evaluated for reliability, reproducibility, sensitivity, species specificity, detection limitations, and assignment accuracy. Six SNPplexes were developed containing 39 intergenic SNPs and 26 phenotypic SNPs, including a sex identification marker, ZFXY. The combined random match probability (cRMP) was 6.58 × 10^?19 across all Western cat populations and the likelihood ratio was 1.52 × 10¹⁸. These SNPplexes can distinguish individual cats and their phenotypic traits, which could provide insight into crime reconstructions. A SNP database of 237 cats from 13 worldwide populations is now available for forensic applications.     

Threat,emboldenment, or both? The effects of political power on violent hate crimes*

How do expressions of support or opposition by the U.S. federal government, influence violent hate crimes against specific racial and ethnic minorities? In this article, we test two hypotheses derived from Blalock's (1967) conceptualization of intergroup power contests. The political threat hypothesis predicts that positive government attention toward specific groups would lead to more hateful violence directed against them. The emboldenment hypothesis predicts that negative government attention toward specific groups would also lead to more hateful violence directed against them. Using combined data on U.S. government actions and federal hate crime statistics from 1992 through 2012, vector autoregression models provide support for both hypotheses, depending on the protected group involved. We conclude that during this period, African Americans were more vulnerable to hate crimes motivated by political threat, and Latinx persons were more vulnerable to hate crimes motivated by emboldenment.     

Is It Race,Class, or Gender? The Sources of Perceived Discrimination in Brazil

Observers have long noted Brazil's distinctive racial politics: the coexistence of relatively integrated race relations and a national ideology of “racial democracy” with deep social inequalities along color lines. Those defending a vision of a nonracist Brazil attribute such inequalities to mechanisms perpetuating class distinctions. This article examines how members of disadvantaged groups perceive their disadvantage and what determines self‐reports of discriminatory experiences, using 2010 AmericasBarometer data. About a third of respondents reported experiencing discrimination. Consistent with Brazilian national myths, respondents were much more likely to report discrimination due to their class than to their race. Nonetheless, the respondent's skin color, as coded by the interviewer, was a strong determinant of reporting class as well as race and gender discrimination. Race is more strongly associated with perceived “class” discrimination than is household wealth, education, or region of residence; female gender intensifies the association between color and discrimination.     

Things Can Only Get Better? Changing Views of the Past,Present and Future in the Former Soviet Union

Previous research has reported substantial levels of nostalgia for the Soviet era among citizens of some of the independent republics that emerged from its collapse. We report new analyses from eight former Soviet republics, and from two surveys, in 2001 and 2010, comparing attitudes to government in the Soviet period and at the time of the surveys, as well as expectations for the future. Everywhere, views of the past have become less positive and those of the present more positive. However, both the views in each survey and the change between each of them vary among countries and socio-demographic groups.
