Detection and quantification of low levels of benzoylecgonine in equine urine

Cocaine (COC) is a highly addictive plant alkaloid expressing strong psychostimulatory effect. It has no medical use in equine veterinary practice. The contamination of the environment with cocaine such as its presence on the US paper currency has been reported few times. There are anecdotal reports of low benzoylecgonine (BE) concentrations (usually much less than 100 ng/mL) being found in urine of race horses. In order to protect horsemen against harsh penalties associated with the presence of trace amounts of BE in horse urine as a result of environmental contamination, in February 2005 the Illinois Racing Board issued new medication rules that established the threshold level of 150 ng/mL for BE in equine urine. The penalties associated with this rule provide for increasing fines ($250, $500, $1000) with successive positive reports against a trainer for levels of BE below 150 ng/mL. A total of 19,315 urine samples were collected over the 2-year period of time from winning horses (both harness and thoroughbred) at race tracks in Illinois for routine drug screening (ELISA). The presence of BE was confirmed by GC/MS in 28 urine samples (0.14%). The concentration range for BE in harness horses (21 detections) was < 5-91 ng/mL, and for thoroughbred (seven detections) was 7-52 ng/mL. To date, the laboratory has not reported concentrations of BE that exceed the established threshold concentration of 150 ng/mL.     

Factors Associated with Separation and Ongoing Violence among Women with Civil Protective Orders

This study examined a large sample of women recruited out of court at the time they received a civil protective order to better understand relationship status after obtaining a protective order (PO) and factors associated with protective order violations. Results are consistent with prior research suggesting that the protective order may be the impetus in separating from the abusive partner for some women, while for other women it is part of the separation process. Results also indicated that five out of ten women who did not continue a relationship experienced a violation while seven out of ten women who did continue a relationship with the PO partner experienced a violation. The majority of women felt safer and reported they believed the protective order was effective 13 months post-PO, regardless of relationship status. Furthermore, stalking played a significant role in separation from an abusive relationship and in protective order violations regardless of relationship status. Implications for practice and future research are discussed.

Mother–infant separations in prison. A systematic attachment-focused review of the academic and grey literature

This review systematically searched UK academic and grey literature in relation to mother and child separation in prison. Attachment theory is referred to in current prison policy for mothers and could provide a framework linking policy and practice. Reviewing grey literature provided an opportunity to explore practice-based literature. Twenty-four academic papers and 51 grey documents were reviewed. Use of attachment theory in the academic literature varied according to discipline, ranging from extensive use to no use. There was greater use of attachment theory in the grey literature. Despite linguistic differences, all documents highlighted the detrimental impact of separation on imprisoned mothers. However, specificity was lacking regarding support for mothers, and staff needs were overlooked. Given its use across the sparse research and practice literature, and its basis for policy, attachment theory could underpin theoretically informed support for imprisoned mothers separated from their infants and staff who support them.     

Reciprocal Relationships between Trajectories of Depressive Symptoms and Screen Media Use during Adolescence

Adolescents are constantly connected with each other and the digital landscape through a myriad of screen media devices. Unprecedented access to the wider world and hence a variety of activities, particularly since the introduction of mobile technology, has given rise to questions regarding the impact of this changing media environment on the mental health of young people. Depressive symptoms are one of the most common disabling health issues in adolescence and although research has examined associations between screen use and symptoms of depression, longitudinal investigations are rare and fewer still consider trajectories of change in symptoms. Given the plethora of devices and normalisation of their use, understanding potential longitudinal associations with mental health is crucial. A sample of 1,749 (47% female) adolescents (10–17 years) participated in six waves of data collection over two years. Symptoms of depression, time spent on screens, and on separate screen activities (social networking, gaming, web browsing, TV/passive) were self-reported. Latent growth curve modelling revealed three trajectories of depressive symptoms (low-stable, high-decreasing, and low-increasing) and there were important differences across these groups on screen use. Some small, positive associations were evident between depressive symptoms and later screen use, and between screen use and later depressive symptoms. However, a Random Intercept Cross Lagged Panel Model revealed no consistent support for a longitudinal association. The study highlights the importance of considering differential trajectories of depressive symptoms and specific forms of screen activity to understand these relationships.     

The Influence of Maternal Acculturation,Neighborhood Disadvantage,and Parenting on Chinese American Adolescents’ Conduct Problems: Testing the Segmented Assimilation Hypothesis

Associations among neighborhood disadvantage, maternal acculturation, parenting and conduct problems were investigated in a sample of 444 Chinese American adolescents. Adolescents (54% female, 46% male) ranged from 12 to 15 years of age (mean age = 13.0 years). Multilevel modeling was employed to test the hypothesis that the association between maternal acculturation and adolescents’ conduct problems could be explained by differences in mothers’ reliance on monitoring and harsh discipline. In addition, guided by segmented assimilation theory, measures of neighborhood disadvantage were expected not only to be related to differences in parenting, but also to moderate the effects of maternal acculturation on parenting. Results indicated that increased maternal acculturation was related to higher levels of maternal monitoring and lower levels of harsh discipline, which, in turn, were related to lower levels of adolescents’ conduct problems. Hierarchical linear modeling results revealed that neighborhood disadvantage was related to lower levels of maternal monitoring. However, neighborhood disadvantage did not moderate the link between maternal acculturation and parenting practices.

Longitudinal Effects of Perceived Maternal Approval on Sexual Behaviors of Asian and Pacific Islander (API) Young Adults

Data were obtained from the National Longitudinal Study of Adolescent Health to examine the longitudinal association between Asian and Pacific Islander (API) adolescents’ perceptions of maternal approval of their sexual activity and contraception use, and four sexual outcomes during young adulthood. The study includes a nationally representative sample of 1,195 API adolescents. Logistic regression analyses were used to estimate the associations between predictors (Wave I) and outcomes (Wave III), controlling for covariates. API adolescents who perceived that their mothers approved of their sexual activities were more likely to have engaged in sex before age 15, contracted HIV/Sexually Transmitted Diseases, had multiple sex partners, and paid money for sex during young adulthood. Findings highlight the need for parent–adolescent communication and parental involvement in preventing negative sexual health outcomes among API adolescents transitioning to young adulthood.

Understanding the effects of perceived ethics failure,compassionate leadership,and communication strategy on anti-government sentiment

This study conceptualizes anti-government sentiment and tests the relationships between anti-government sentiment and three antecedents (i.e., ethics failure, compassionate leadership, and communication strategy). An online survey (n = 1,112) was conducted in South Korea. Exploratory factor analysis with principal component analysis and confirmatory factor analysis was conducted on the measures proposed for anti-government sentiment. The hypotheses were tested using structural equation modeling. Results show that publics' perceptions of the government's ethics failure, lack of compassionate leadership, and use of a buffering strategy for communication are positively related to their anti-government sentiment toward the incumbent government.     

Coproducing the Endangered Polar Bear: Science,Climate Change,and Legal Mobilization

Applying insights from science and technology studies about the “coproduction” of science and sociopolitical order to research on legal mobilization yields important theoretical insights. Using the polar bear petition campaign by the Center for Biological Diversity as an illustrative case, this article shows how this protracted legal campaign around protection of the polar bear and its habitat opened up new legal opportunities for those advocating for the regulation of carbon emissions, mandated state-sponsored generation of climate science, legally constructed the polar bear as “endangered,” and helped to shape the priorities of the nongovernmental organization itself.     

Nudging Early Reduces Administrative Burden: Three Field Experiments to Improve Code Enforcement

In the past decade, public sector organizations around the world have worked to simplify administrative processes as a way to improve user experience and compliance. Academic evidence on administrative burden supports this approach and there is a strong body of research showing that learning costs, compliance costs, and psychological costs help to explain why residents do not always take up programs for which they are eligible. This article considers the role of these types of costs in a different set of resident-state interactions: compliance with regulations. We present the results of three large field experiments aimed at improving resident compliance with municipal housing codes using targeted behavioral interventions. We find that contacting property owners earlier, redesigning first notices, and proactively communicating with previous violators, can significantly improve compliance by 14.7 percent, 3.3 percent, and 9.2 percent, respectively, with costs savings ranging from 6 to 15 percent of a city's annual enforcement budget. Our results counterintuitively suggest that sometimes adding steps to an administrative process can reduce the costs associated with the resident-state interaction.
