Multiple stable isotope characterization as a forensic tool to distinguish acid scavenger samples

Acid scavengers are frequently used as stabilizer compounds in a variety of applications. When used to stabilize volatile compounds such as nerve agents, the lower volatility and higher stability of acid scavengers make them more persistent in a post-event forensic setting. Compound-specific isotope analysis of carbon, nitrogen, and hydrogen in three acid-scavenging compounds (N,N-diethylaniline, tributylamine, and triethylamine) were used as a tool for distinguishing between different samples. Combined analysis of multiple isotopes improved sample resolution, for instance differentiation between triethylamine samples improved from 80% based on carbon alone to 96% when combining with additional isotope data. The compound-specific methods developed here can be applied to instances where these compounds are not pure, such as when mixed with an agent or when found as a residue. Effective sample matching can be crucial for linking compounds at multiple event sites or linking a supply inventory to an event.     

Family Violence and Children’s Behavior Problems: Independent Contributions of Intimate Partner and Child-Directed Physical Aggression

Using data from a diverse sample of 581 families living in predominantly low-income, rural communities, the current study sought to investigate the longitudinal associations among father-perpetrated intimate partner violence (IPV) and child-directed physical aggression perpetrated by the mother. The unique contributions of each of these types of family violence on children’s behavioral problems at school entry were also examined. Results confirm bidirectional associations between father-perpetrated IPV and maternal physical aggression directed toward the child, and indicate that both types of physical aggression contribute to child behavior problems at school entry.     

CHINA RESPONDS

Imagine the U.S.Government shutting down almost all forms of public transportation,a substantial number of international airline flights,all schools and many businesses during the period between Thanksgiving through the end of the Christmas season and beyond.That is what is currently going on in Wuhan,the epicenter of the novel coronavirus outbreak,with what has become possibly the largest quarantine in human history.     

How Ideology Fuels Affective Polarization

Scholars have reached mixed conclusions about the implications of increased political polarization for citizen decision-making. In this paper, we argue that citizens respond to ideological divergence with heightened affective polarization. Using a survey experiment conducted with a nationally representative sample of U.S. citizens, we find that increased ideological differences between political figures produce increasingly polarized affective evaluations, and that these differences are especially large among respondents with stronger ideological commitments and higher levels of political interest. We provide further support for these findings in an observational study of citizens’ evaluations of the U.S. Senators from their state. We also find that the polarizing effects of ideological differences can be largely mitigated with biographical information about the public officials, which suggests that the pernicious consequences of ideological polarization can be overcome by focusing on matters other than political disagreement.     

Ingredients of institutional reputations and citizen engagement with regulators

The purpose of this study is to examine the link between the reputational components of efficacy and moral reliability of institutions, and citizens' compliance with institutional recommendations. Research on bureaucratic reputations highlights the significance of positive political reputations based on credibility and legitimacy, but the impact of these components is not systematically isolated and studied. We draw insights from political psychology to move beyond a positive‐negative valence‐based approach of reputation, and highlight the different effect of efficacy and moral reliability components of reputation on citizens' cooperation, engagement in water saving activities, and levels of complaints. We use the Cypriot Water Authority as a case study and inquire how its institutional reputation influences Cypriot citizens' behavior regarding water use. Our data was collected via a representative national survey administered to a random sample of 800 Cypriots in the spring of 2009 and show that favorable perceptions of particular components of institutional reputation shape the levels of satisfaction with specific organizational outputs.     

'Just War' or Just War? The Future(s) of a Tradition

The greatest virtue of the just war lies in its ability to pass judgement on war (the announced aims) and its conduct (the adopted strategy). But how coherent is this synthesis of ideas that assumes a unity between force, political expediency and morality? Can individual wars be morally assessed, and how useful is the just war in this respect? This article assesses the modern relevance of the tradition before suggesting directions for further research in the light of the recent Kosovo Crisis.     

Policy Transfer and Policy Learning: A Study of the 1991 NewZealand Health Services Taskforce

Research into policy transfer and lesson drawing has been criticized asfew authors have convincingly shown how cross-national policy learning actually influences policy formation in a particular jurisdiction. This article addresses this gap by presenting a study of the development of the 1991 health policy in New Zealand. By studying the process of policy development, rather than just a policy document, it was possible to disaggregate different aspects of the policy and to identify sources and influences. This article finds that the 'conspiracy' model of policy formation does not fit this case as it presents an overly simplistic view, which allows little space for policy learning. This case illustrates the subtle and multifaceted influence of different jurisdictions, different institutions, and different individuals on a given policy.     

False Profits: Why Product Counterfeiting is Increasing

Product counterfeiting has grown in scope, scale and complexity in the last two decades, and now affects many areas of manufacturing and retailing from clothes and CDs to items such as shampoo and vehicle components. Based on a wide range of interviews in the UK, this article argues that despite recent legislative change and increased criminal penalties for counterfeiters, enforcement is haphazard, resource problems often dictate that no criminal prosecution is undertaken, and actual penalties remain low. Moreover, questions of whether or not a particular item is counterfeit have become greatly complicated by the development of outsourcing and the rise of parallel trading. These points suggest that counterfeiting is likely to grow in the future.
