Concentrations of ethanol in two segments of the vascular system.

The time courses of capillary and venous blood concentrations of ethanol after oral administration of 0.30 and 0.34 g/kg doses of ethanol to two normal human subjects indicated that, by interpolation, equal capillary and venous concentrations are reached at only one time, and this time varied with the subject. The capillary/venous blood concentration ratios varied markedly as a function of time in both subjects over the entire observation period of 4 h.     

Enhancing sustainable development in Sub-Saharan Africa: concepts,recommendations and illustrations

In recent years, the concept of sustainable development has received renewed attention. As global resources shrink and needs continue to grow, the staying power of development impact is becoming central concern of both governments and donors. Recent studies have shown that only a small percentage of projects throughout the world have achieved sustainability, and the need for improving the long-term vitality of development investments is growing. No area in the world has shown more need of this than Africa. This paper outlines a conceptual approach for analyzing sustainability and synthesizes the lessons learned from the application of this model in recent field work. The model is based on the theory that two preconditions must exist before sustainability can occur: 1 ) commitment to long term sustainable development; and 2) beneficiary and stakeholder involvement via incentives which support achieving sustainability . Fieldwork-based recommendations to enhance sustainability include: 1) understand the long-term incentive structure that drives the project; 2) identify performance targets and communicate results early-on; 3) identify long-term recurrent costs and funding options; 4) build in flexibility to the project plan; 5) build-in ways for participants to support and “take ownership” of the project; 6) use local resources, both human and physical, and keep technologies simple; and 7) use marketing strategies to reinforce perceived, satisfactory benefits of the project. Case examples of successful African projects from West Africa, Burkina Faso and Kenya illustrate the application of the sustainability concepts. In the context of these illustrations, the sustainability framework appears useful for understanding and analyzing sustainability and provides a necessary addition to thinking about development projects and programs.     

Is Germany Going Bananas? Life Cycle and Cohort Effects on Party Performance in Germany from 1953 to 2049

In the public debate concerning the consequences of demographic change in Germany it is often argued that the rising share of older voters will help the CDU/CSU to consolidate its power. This argumentation only applies if the age effect is assumed to be dominant. However, diverse socialisation backgrounds, captured by the cohort effect, also have to be taken into account. Based on the Repräsentative Wahlstatistik (Representative Electoral Statistic, RES) and Population Forecasts, the consequences of demographic shifts for federal elections since 1953 are estimated, as well as for future elections. First, age, cohort and period effects on vote choice for previous elections are calculated by using cohort analysis. Second, these effects are applied to the future age distribution. The results show that the ‘greying’ electorate is expected to favour the CDU/CSU and the FDP, while especially the SPD is likely to suffer electoral losses due to demographic shifts.     

Indonesia's democratic stagnation: anti-reformist elites and resilient civil society

As Egypt and Tunisia begin difficult democratic transitions, comparative political scientists have pointed to the world's largest Muslim nation, Indonesia, as a role model. Seen as a stand-out exception from the global recession of democracy in the pre-2011 period, Indonesia has been praised as an example of a stable post-authoritarian polity. But a closer look at Indonesia's record in recent years reveals that its democratization is stagnating. As this article demonstrates, there have been several attempts to roll back reforms introduced in the late 1990s and early 2000s. While not all of these attempts have been successful, Indonesia's democratic consolidation is now frozen at 2005–2006 levels. However, the reason for this democratic stasis, the article argues, is not related to Diamond's notion of societal dissatisfaction with bad post-authoritarian governance. Opinion polls clearly show continued support for democracy despite citizen disgruntlement over the effectiveness of governance. Instead, I contend that anti-reformist elites are the main forces behind the attempted roll back, with civil society emerging as democracy's most important defender. This insight, in turn, questions the wisdom of the decision by foreign development agencies – in Indonesia, but other countries as well – to reduce their support for non-governmental organizations and instead intensify their cooperation with government.     

The Quantitation of Cocaine on U.S. Currency: Survey and Significance of the Levels of Contamination

It has long been suspected that the illicit distribution of cocaine in the United States has led to a large‐scale contamination of the currency supply. To investigate the extent of contamination, 418 currency samples (4174 bills) were collected from 90 locations around the United States from 1993 to 2009. The extent of their cocaine contamination was quantitated via gas chromatography/mass spectrometry or liquid chromatography/mass spectrometry. The level of cocaine contamination was determined to average 2.34 ng/bill across all denominations ($1, $5, $10, $20, $50, and $100). Levels of cocaine contamination on currency submitted to the Federal Bureau of Investigation Laboratory in criminal cases over the 1993–2001 timeframe had significantly higher contamination than currency in general circulation. A mathematical model was developed based on the background survey that indicates the likelihood of drawing a bill in specific concentration ranges. For example, there is a 0.8349 likelihood that random bill will have contamination less than 20 ng.     

Standardization of Histological Procedures for the Detection of Toxic Substances by Immunohistochemistry in Dipteran Larvae of Forensic Importance

Immunohistochemistry (IHC) technique is an alternative toxicological analysis to detect drugs in insects of forensic importance, but it requires thorough histological procedures. In this study, we tested different fixatives—phosphate‐buffered paraformaldehyde 4% (PP), Carnoy's fluid (CF), Kahle's solution (KS), ethanol in different concentrations, and ethanol associated to PP and CF, time of fixation and histological processes for dipteran larvae's tissue, aiming to develop a sample preparation protocol for IHC application. A suitable fixation was achieved using PP for 12 and 24 h, CF for 3 h, 70% ethanol for 19 days, and 70% ethanol/CF for 2 h/3 h. Postfixation using negative pressure, two immersions in xylene for 30 min each, and one in xylene plus paraffin for 45 min increased tissue preservation. An immunohistochemical test for cocaine detection was performed using monoclonal benzoylecgonine antibody from mouse, peroxidase‐conjugated anti‐mouse IgG and visualized by 3,3′‐diaminobenzidine method showed these histological procedures didn't compromise antigenicity.     

Editorial

ABSTRACT

The current paper examined the association between childhood sexual victimization (CSV) and constructs thought to be relevant for sexual offending in secondary analyses of three samples of adult males who committed sexual offences against children (N?=?16, 28, and 20). Compared to participants who reported no CSV, those who reported CSV exhibited slightly to moderately more cognitive distortions and moderately to largely less negative evaluations of sexual offending against children; slightly to moderately higher self-esteem, positive evaluation of people who commit sexual offences, and identification with people who commit sexual offences against children; and much more emotional congruence with children. Our findings suggest that CSV may be associated with variables presumed to play a role in sexual offending against children. However, given the small sample sizes and other limitations of our studies, our evidence does not permit conclusions regarding causal relationships and any novel findings require replication.     

The Impact of Children on Legal Actions Taken by Women Victims of Intimate Partner Violence

Successful criminal or civil legal system response to assaults against intimate partners (intimate partner violence; IPV) usually rely on the victim’s participation in the legal process, including having contact with the prosecutor, filing charges, and/or applying for an order of personal protection. Using data abstracted from criminal and civil legal system records for a county-wide cohort of 990 female IPV victims over a 4-year period, we examine the impact of having children, and of specific child factors, on victims’ engagement with the criminal prosecution of their abusive partners and/or seeking a personal protection order (PPO) in the civil court system. Having children increased victim’s contact with the prosecutor and applications for PPOs, but did not increase her likelihood of wanting to file or drop charges. Findings support prior work suggesting both the importance and complexity of children on mothers’ decision-making. Policy makers and service providers may want to assess survivors’ thoughts about the role children play in their decision-making. Additionally, by offering survivors interventions to help their children address the impact of IPV exposure, survivors may be more willing to engage with services.

Dynamics of Polarizing Rhetoric in Congressional Tweets

Affective polarization is pervasive in modern US politics, and can be intensified by strategic messaging from members of Congress. But there are gaps in our knowledge of the dynamics of polarizing appeals from elected representatives on social media. We explore the usage of polarizing rhetoric by members of Congress on Twitter using the 4.9 million tweets sent by members of Congress from 2009 to 2020, coded for the presence of polarizing rhetoric via a novel and highly accurate application of supervised machine learning methods. Fitting with our expectations, we find that more ideologically extreme members, those from safer districts, and those who are not in the president’s party are more likely to send polarizing tweets, and that polarizing tweets garner more engagement, increasing campaign funding for more polarizing members.
