Anticipated Mortality,HIV Vulnerability,and Psychological Distress Among Adolescents and Young Adults at Higher and Lower Risk for HIV Infection

This study described multivariate patterns of associations among psychological distress, anticipated mortality, and perceived vulnerability to HIV among urban, multiethnic samples of (a) adolescents (N = 120) undergoing substance abuse treatment, and (b) young adult university students (N = 222). While there were significant correlations between (a) psychological distress and reported vulnerability to HIV in the treatment sample; and (b) psychological distress and anticipated mortality in the university sample, there was no significant relation between anticipated mortality and perceived vulnerability to HIV in either sample. Cluster analysis revealed four distinct and meaningful groups in both samples, including parallel high- and low-functioning subgroups. Multivariate group differences in both samples were validated via corresponding group differences in (a) motives for drinking during sex, and (b) markers of serious psychological distress (e.g., suicidal thoughts and attempts). The findings challenge popular sterotpes of adolescents' perceptions of their own mortality and vulnerability to HIV and may have significant implications for the planning and implementation of effective HIV preventions among at-risk youth.     

Bring back the party: personalisation,the media and coalition politics

What effect, if any, does a change in type of government have on the degree of media personalisation? This article argues that the different incentives that single- and multi-party governments provide to individual politicians and parties affect the level of media personalisation. Where the parties are more involved (i.e. multi-party coalitions) there will be less media personalisation. In contrast, where a single individual can command the party, there will be more media personalisation. The article tests these assumptions with a novel dataset created from over 1 million newspaper articles covering a continuous 24-year period in the UK. It finds that the switch to a coalition government in 2010 indeed changed the dynamics of media personalisation. These findings not only provide key insights into the phenomenon of personalisation but also enable us to better understand some of the potential consequences of changes in government types for power dynamics and democratic accountability.     

Developing political trust in a developing country: the impact of institutional and cultural factors on political trust in Ghana

Political distrust is often widespread in African countries, but the prospects for increasing trust are uncertain given the lack of research on the origins of political trust in the region. Using the 2013 NSS Survey in Ghana and employing hierarchical regression analyses, we develop a model of institutional trust based on insights from both cultural and institutional performance theories. The results clearly support the superiority of institutional performance theories while at the same time providing limited support for cultural explanations. National pride, however, does also substantially encourage institutional trust. This asks for future, cultural-specific studies on trust-building in developing countries trying to establish working institutions using more representative, cross-national, and longitudinal data.     

Using Frons Width to Differentiate Blow Fly Species (Diptera: Calliphoridae) Phormia regina (Meigen) and Protophormia terraenovae (Robineau‐Desvoidy)

Protophormia terraenovae (Robineau‐Desvoidy) (Diptera: Calliphoridae) and Phormia regina (Meigen) (Diptera: Calliphoridae) are morphologically similar blow fly species commonly used for estimating postmortem intervals. Field collection and storage of adults can result in color changes, in particular on calypters and palps; often collected specimens show damage such as wing fray or fungal growth. We measured the frons width: total head width ratio using photographs (ImageJ version 1.49) to differentiate these two species. Both sexes were distinguishable to species, with the greatest difference between males: 12.34% P. terraenovae versus 1.62% P. regina, less so for females: 40.25% P. terraenovae, versus 33.65% P. regina. Incorporating this feature into future blow fly keys would help with distinguishing field‐caught specimens when other features are obstructed.     

To address or not to address the violent past in the classroom? That is the question in Côte d’Ivoire

In the aftermath of violent conflict, divided societies have to answer the important question of whether, when and how to address their country’s violent past within their educational system. Whereas some scholars within the field of peace education and transitional justice argue that addressing the violent past in the classroom is important for fostering mutual understanding and empathy among future generations in order to prevent conflict recurrence, other scholars are more sceptical about the need and feasibility of addressing the violent past in schools. They emphasize the possible negative impact in terms of increased tensions within schools and within society more generally. The current paper makes an important empirical contribution to this debate by analysing the views and perceptions on this matter of 984 secondary school teachers in Abidjan, the largest city and de facto capital of Côte d’Ivoire – a country that was recently torn apart by ethnic strife and violent conflict. It emerges that while so far most teachers have shied away from addressing their country’s conflict history in class, it also appeared that many of the teachers were actually in favour of breaking this culture of silence.     

Cleavage of synthetic pentazocine glucuronide with hydrochloric acid

It has been reported before that pentazocine (I) and pentazocine-glucuronide (II) form an artifact (III) by the addition of water to the double bond in the presence of HCl. This reaction leads to different results concerning the investigation of the rate of hydrolysis of II and the recovery of I. The glucuronide was quantitatively hydrolyzed by 20% HCl, but yielded only 15% of I (about 64% was detected as III). With 5% HCl the rate of hydrolysis only amounted to 40%-43%, whereas I yielded 31% (only 9% was recovered as III). The best III yield was obtained with a HCl concentration of 17.5%.
