Study of the adhesion of explosive residues to the finger and transfer to clothing and luggage

It is important to understand the extent of transfer of explosive particles to different surfaces in order to better evaluate potential cross-contamination by explosives in crowded security controls such as those at airports. This work investigated the transfer of nine explosive residues (ANFO, dynamite, black powder, TNT, HMTD, PETN, NH₄NO₃, KNO₃, NaClO₃) through fingerprints from one surface to another. First, the extent of adhesion of explosive residues from different surfaces to the bare finger, nitrile and latex gloves was studied. Then, the transfer of explosive residues from one surface to another through fingerprints was investigated. Cotton fabric (hereinafter referred to as cotton) as clothing material and polycarbonate plastic (hereinafter referred to as polycarbonate) as luggage material were chosen for the experiments. These surfaces containing explosive particles were imaged using a reflex camera before and after the particles were transferred. Afterwards the images were processed in MATLAB where pixels corresponding to explosive residues were quantified. Results demonstrated that transfer of explosive residues frequently occurred with certain differences among materials. Generally, the amount of explosive particles adhered to the finger decreased in the following order: skin>latex>nitrile, while the transfer of particles from the finger to another surface was the opposite. The adhesion of explosive residues from polycarbonate to the finger was found to be better compared to cotton, while the amount of particles transferred to cotton was higher.     

Institutional Change and Professional Norms: A Study of Grading Behavior in Higher Education

This study investigates how an institutional exogenous change interacts with professional norms in relation to behavior in public organizations. We test how a new grading scale introduced in 2007 changed grade point averages and pass rates at two university departments. Data consist of register data on grading between 2004 and 2010. We find that the new grading scale both increased grade point averages and pass rates and halted the negative time trend in these variables. These effects are even greater for exams with an external examiner. The main conclusion is that grading systems affect grading both immediately and over time.     

Children's reporting patterns after witnessing homicidal violence – the effect of repeated experience and repeated interviews

For both legal and clinical purposes, it is of importance to study children's memories and reports of stressful events. The present study investigated the reporting patterns of 83 children who had witnessed homicidal violence, which is considered to be a highly stressful experience. More specifically, we explored the possible effects of prior violence exposure and of repeated questioning on the amount of details reported. Results showed that the majority of children provided detailed reports about the homicidal violence they had witnessed, including details concerning what happened before, during, and after the violent act. The children provided detailed and vivid testimonies from their experiences, whether they witnessed the event for the first time or had prior experience of witnessing severe violence against the victim by the perpetrator. Children with no prior experience of repeated violence who underwent repeated interviews provided more details than those interviewed once. The present data indicate that children are competent witnesses when questioned in legal contexts after having been exposed to extremely stressful events. These findings have implications for research related to children's memories and reporting of traumatic experiences, as well as practical implications for future treatment and evaluation of children's testimonies.     

Globalisation,workers and the northern league

This article seeks to explain why the Northern League's main basis of support now comes primarily from Northern workers and artisans. To explain the nature of the League's support, we hypothesise that a fear of globalisation has led workers in the north to vote for the party that has put the greatest emphasis on the protection of local identities. We analyse survey data to document the affect globalisation has on the voting patterns of Northern workers. From our data, we construct a regression model to identify the issues and socioeconomic factors that predict support for the Northern League. In addition to the regression model, we also present cross‐tabulated data revealing that Northern League supporters tend to be extremely provincial, yet they are convinced that global forces are threatening their quality of life.     

Duopoly,court politics and the Danish core executive

This article applies the ideas of the core executive and court politics to Danish coalition and minority governments. It asks two questions. Do these ideas travel beyond their Westminster origins? What are the dilemmas confronting the Danish executive and its court politics? The analysis is based on documentary sources and 22 elite interviews with cabinet ministers and permanent secretaries. It identifies a duopoly of Prime Minister and Minister of Finance as a distinctive variety of court politics. It identifies the key dilemmas confronted by the Danish executive; namely trust, political support and politicization. It concludes that court politics provides unique insights into the workings of Danish government. The article is a contribution to the comparative analysis of the court politics of governing elites. It shows that the focus on court politics is not only useful for majoritarian Westminster systems but also for the analysis of consensual parliamentary democracies.     

Monopoly and Transition to the Market

An American economist describes recent Soviet thinking on monopoly and traces its impact on the reform process up until 1991. After an overview of industrial concentration in the Soviet economy, the study proceeds to examine the content of Gorbachev's antimonopoly policy, focusing on policy toward dominant firms, mergers, and entry of firms. Drawing on this background and antitrust experience in Western countries, it concludes by analyzing the role of antitrust policy and import competition in the transition to the market.

Transforming Teens: Measuring the Effects of Restorative Justice Principles in a Teen Court Setting

This paper examines the impact of restorative justice principles in a teen court setting. Specifically, our research attempts to quantitatively measure learning of certain restorative justice principles through the teen court process by comparing matched, pre‐ and post‐survey responses to questions involving the adolescent's ability to understand their crime as a violation of relationships within their community, as opposed to merely a violation of law. Qualitative responses regarding the efficacy of the teen court program from both teen participants and their parents are also examined in the context of restorative justice principles. Finally, the efficacy of the teen court model is discussed in terms of recidivism rates compared to teens who do not experience the teen court process.
