Age at Menarche and Adolescent Alcohol Use

Research has shown that early maturation is related to problematic alcohol use, yet the differential effect of early pubertal timing (i.e., younger age at menarche) on the onset of alcohol use and subsequent level of alcohol use has rarely been examined. This distinction is relevant, as younger age at menarche can have differential effects on these outcomes, which in turn can have long-lasting effects. Therefore, the present study examined the relationship between age at menarche and adolescent alcohol use among girls, hereby distinguishing between onset and level of alcohol use. In addition, the moderating effects of alcohol-specific rules, child disclosure and class gender composition were examined. Participants were 430 girls from a Dutch four-wave survey, with a mean age of 12.17 years (SD = 0.50) at the beginning of the study. Results showed that the probability of onset of alcohol use was increased by younger age at menarche, but only when girls were younger than 15. Moderation analyses showed that younger age at menarche increased the risk of alcohol onset only in low risk girls (with high levels of alcohol-specific rules and in classes with a high percentage of girls). Once adolescent girls started drinking alcohol, younger age at menarche was associated positively with alcohol consumption only for girls in classes with a moderate to high percentage of girls. These findings confirm that younger age at menarche is a risk factor for the onset of alcohol use, but strongly suggest that this effect is strongest for girls having restrictive alcohol-specific rules and in classes with a high percentage of girls. Possibly, in the absence of social factors that “push” to alcohol use, biological factors (like age at menarche) become more important. Another possibility is that adolescent girls start drinking alcohol to oppose their parents if they set too strict alcohol-specific rules.     

Teaching for Implementation: Designing Negotiation Curricula to Maximize Long-Term Learning

Most negotiation students — and their instructors — aspire to develop negotiation skills that they can transfer to real-world contexts beyond the classroom. Instructors can maximize the likelihood of long-term learning through transfer-oriented curriculum design. Curriculum design elements likely to support lasting and flexible learning include (1) articulation of clear, performance-oriented goals; (2) careful selection of a range of learning activities tailored toward those goals, including activities that promote schema development and adjustment, activities that promote behavioral skill development, and activities that reinforce explicit theoretical understanding; (3) provision of multiple opportunities for constructive feedback from a variety of sources; and (4) the facilitation of self-reflection and metacognition.     

Interactions Between Rejection Sensitivity and Supportive Relationships in the Prediction of Adolescents’ Internalizing Difficulties

Rejection sensitivity, the tendency to anxiously or angrily expect rejection, is associated with internalizing difficulties during childhood and adolescence. The primary goal of the present study was to examine whether supportive parent–child relationships and friendships moderate associations that link angry and anxious rejection sensitivity to depression and social anxiety during middle adolescence in an ethnically diverse sample of 277 youth (M age = 14.30 years; 46.93% male). Analyses revealed that angry rejection sensitivity was related to depressive symptoms, but only for adolescents reporting low support from parents and friends. Friend support moderated the association between (1) angry rejection sensitivity and social anxiety, and (2) anxious rejection sensitivity and depressive symptoms. For adolescents reporting low support from friends, support from parents was positively related to social anxiety. Findings highlight the importance of considering relationships in studies of rejection sensitivity and adjustment during adolescence.     

Encouraging Writing on the White Walls: Co‐production in Museums and the Influence of Professional Bodies

Museums, along with other public sector organisations, have been urged to co‐produce. Co‐production may offer increased resourcing and greater effectiveness, and enhances public value through stronger relationships between government and citizens. However, co‐production, particularly that which involves collaboration with communities, is largely resisted by public sector organisations such as museums. This research examines the extent to which museums co‐produce and the role played by professional bodies in driving or inhibiting co‐production. It finds that the study of co‐production in museums reveals the influence of ‘institutional inertia’ and the limits to which professional bodies are able to ‘diffuse’ co‐production and change established professional practice.     

Analysis of 2,4-Dinitrophenol in Postmortem Blood and Urine by Gas Chromatography–Mass Spectrometry: Method Development and Validation and Report of Three Fatalities in the United States

2,4-dinitrophenol (2,4-DNP) is a compound used in the early 1900s as a weight-loss drug but later prohibited due to its severe adverse effects, including death. It has however been attracting interest, due to its weight-loss properties, and appears to be re-emerging in forensic casework. As 2,4-DNP is available for use in industry and as a pesticide and easily accessible online, the dissemination of this drug can be fast. The compound exerts its effects through inhibition of ATP synthesis, and corresponding thermogenic energy loss which can be fatal. A method for qualitative and quantitative analysis of 2,4-DNP in blood and urine specimens using GC-MS with hydrogen as carrier gas is described. The method was validated and displayed acceptable performance parameters with linearity (R² higher than 0.998), inter-assay imprecision (lower than 10.6%), intra-assay imprecision (lower than 10.7%), and extraction efficiency (92.1%). Stability of 2,4-DNP in blood and urine was studied, and the drug was stable up to 30 days refrigeration or frozen. Six cases in United States suspected to be related to 2,4-DNP were analyzed. Three cases were found to be positive for 2,4-DNP. Concentrations of 2,4-DNP were in the range of 61.6–220 mg/L in urine and <3–114 mg/L in blood. Based on our findings, we suggest that medical examiners and forensic toxicologists be aware of the reappearance of 2,4-DNP, including this compound as a target in death investigations related to weight-loss drugs.

Buying Amendments? Lobbyists' Campaign Contributions and Microlegislation in the Creation of the Affordable Care Act

When do campaign contributions matter? This article advances the claim that a group that gives campaign contributions to US Members of Congress is more likely to achieve legislative success when (1) a single legislator can deliver to the group (2) a private benefit (3) without attracting negative attention. Using an original data set based on the written comments of nearly 900 interest groups lobbying the US Senate Finance Committee on health reform legislation in 2009, I link group requests to corresponding legislation. The analysis shows a significant relationship between lobby groups' campaign contributions and their legislative success, and at distinct units of analysis—the group, the side, and the group-senator dyad. The relationship is particularly strong in predicting senators’ amendments in committee. The rare data presented here offer compelling evidence that interest groups' legislative victories are sometimes connected to campaign contributions in a way that previous studies could not identify.
