Analysis of Explosives by GC‐UV

A mixture of explosives was analyzed by gas chromatography (GC) linked to ultraviolet (UV) spectrophotometry that enabled detection in the range of 178–330 nm. The gas‐phase UV spectra of 2,4,6‐trinitrotoluene (TNT), 2,4‐dinitrotoluene (DNT), ethylene glycol dinitrate (EGDN), glycerine trinitrate (NG, nitroglycerine), triacetone triperoxide (TATP), and pentaerythritol tetranitrate (PETN) were successfully recorded. The most interesting aspect of the current application is that it enabled simultaneous detection of both the target analyte and its decomposition products. At suitable elevated temperatures of the transfer line between the GC instrument and the UV detector, a partial decomposition was accomplished. Detection was made in real time and resulted in overlaid spectra of the mother compound and its decomposition product. Hence, the presented approach added another level to the qualitative identification of the explosives in comparison with traditional methods that relies only on the detection of the target analyte. As expected, the decomposition product of EGDN, NG, and PETN was NO, while TATP degraded to acetone. DNT and TNT did not exhibit any decomposition at the temperatures used.     

Molding Minds That Form Policy: How to Make Research Useful

How can policy-relevant ideas be effectively communicated to practitioners? While the existing literature has focused on what kind of theory and research are policy relevant, it does not say much about how this knowledge can be communicated. If you want to make a difference, you must know how to reach your target. We take note of the important, but in this context often overlooked opportunities for knowledge diffusion that are provided by the education of young minds and the training of mid-career officials and officers. This article first discusses three contending perspectives on the relationship between scholars and practitioners. It then makes a conceptual elaboration of conditions for communicating research to practitioners, drawing on a wide body of literature on the power of ideas. We conclude by summarizing pointers for how scholars may reflect and how we can act, if we wish to enrich foreign policy practice with research-based ideas.     

Daunorubicin-induced chronic cardiomyopathy — An experimental model system for study of sudden death. A preliminary report

Experimental cardiomyopathy in terms of heart hypertrophy and noninflammatory myocardial lesions was induced in rabbit by i.v. administration of anthracycline antibiotic daunorubicin during 2 to 12 weeks. The animals showed a high rate of unexpected mortality in comparison with controls. This mortality was evaluated from the point of view of the unexpected death as a forensic pathologic term.     

A defence model for the Baltic states

It is often argued that the Baltic states should not be accepted in NATO because they are not defensible and NATO forces would not be able to intervene in time if they were attacked. This article presents a possible Baltic defence concept which appears to be well adapted to Baltic terrain and Baltic material and manpower resources, and which should at the very least impose significant delay (weeks) and heavy losses on a massive attack. Friendly intervention could be in the form of air strikes against aggressor columns blocked on the roads.     

Analyzing Criminal Trajectory Profiles: Bridging Multilevel and Group-based Approaches Using Growth Mixture Modeling

Over the last 25 years, a life-course perspective on criminal behavior has assumed increasing prominence in the literature. This theoretical development has been accompanied by changes in the statistical models used to analyze criminological data. There are two main statistical modeling techniques currently used to model longitudinal data. These are growth curve models and latent class growth models, also known as group-based trajectory models. Using the well known Cambridge data and the Philadelphia cohort study, this article compares the two “classical” models—conventional growth curve model and group-based trajectory models. In addition, two growth mixture models are introduced that bridge the gap between conventional growth models and group-based trajectory models. For the Cambridge data, the different mixture models yield quite consistent inferences regarding the nature of the underlying trajectories of convictions. For the Philadelphia cohort study, the statistical indicators give stronger guidance on relative model fit. The main goals of this article are to contribute to the discussion about different modeling techniques for analyzing data from a life-course perspective and to provide a concrete step-by-step illustration of such an analysis and model checking.

Reading level and the prevalence of a dyslexic profile among patients in a forensic psychiatric clinic

This study aims to investigate Swedish language reading ability of forensic patients and the number of them that present a dyslexia profile. Another aim is to compare the reading level in different subtypes of psychiatric diagnoses. Assessments were made of 185 patients by a battery of reading tests. They were also interviewed about their schooling and their self-estimated reading and writing ability. The results show that the patients’ reading level is below average for grade six children in Swedish compulsory school, and that 16 per cent show a dyslexic profile. Male patients with an immigrant background and a diagnosis of psychosis and anxiety disorders perform the lowest when measuring literacy skills. This proportionately low reading ability can cause difficulties in understanding texts as presented in broadsheet newspapers, civic information and patient records, and might even jeopardize the understanding of adult spoken language.     

Coping with transnationalism in Northern Europe

This report communicates findings on the management techniques devised to cope with the effects of transnationalism in Northern Europe. The most important aspect of this collective policy coordination effort is extensive and intensive interactions among governmental elites across national boundaries. Recently, an effort has been made to increase central, cabinet control of these trans‐Nordic activities. The national bureaucracies remain the most crucial actors while the regional officials have an influence on outcomes to the extent that they can mobilise political commitments or transgovernmental coalitions.     

Refinement and Preliminary Testing of an Imagery-Based Program to Improve Coping and Performance and Prevent Trauma among Urban Police Officers

Police officers are regularly exposed to traumatic critical incidents. The substantial mental, behavioral, and social costs of police trauma indicate a substantial need for prevention. We have refined and enhanced a previously tested Swedish program to the harsh conditions of U.S. inner cities. The program was designed to strengthen resilience during stressful encounters and teach methods of coping after exposure, thereby preventing the emergence of maladaptive symptoms and behaviors with adverse effects on professionalism. In an uncontrolled demonstration project, junior officers were trained by senior officers to engage in imaginal rehearsal of specific dangerous situations while incorporating optimal police tactics and healthy emotional reactions. A class of 32 officers in the police academy engaged in the program, and they and the trainers reported high satisfaction with it. After their first year of field work, 22 officers were reassessed. Compared to pre-training, these officers showed significant increases in the use of positive reframing and humor and significant reductions in anxiety and alcohol use over the year. Trauma symptoms did not increase. These results offer preliminary evidence for the feasibility and effectiveness of this trauma prevention program for new police officers.
