Trends in the Perpetration of Physical Aggression among Norwegian Adolescents 2007–2015

Most research on trends in physical aggression has shown declining levels among adolescents during the past two decades. However, few studies have attempted to explain such time trends. Based on two representative cross-sectional surveys of students in the final year of high school in 2007 (N?=?6631; 58.8% girls) and 2015 (N?=?4145; 60.3% girls), this study reports a substantial decline in physical aggression among Norwegian adolescents. Moreover, mediation analyses show that declining levels in problematic alcohol use and family violence during the same period are plausible explanations for some of this reduction. The results are discussed in light of contemporary changes in socialization of adolescents, and implications for violence prevention are presented.     

Exploring the foundational origins of public service motivation through the lens of behavioral genetics

Despite the proliferation of research on public service motivation (PSM), fundamental questions about its origins continue to evade scholars: Is PSM driven by genetics, socialized through experiences, or both? If PSM is socialized, when does socialization occur? Answering these questions is critical for reconciling the state versus trait debate, and for assessing the validity of practical implications prescribed by PSM studies. Utilizing “nature's own experiment,” we adopt a classical twin design with 1035 twin pairs to identify how genetic heritability, a common environment, or unique environment and experiences can explain variation in PSM. Results show that PSM is heavily influenced by individuals' unique environments and experiences; not by genetics. This lends strong evidence to PSM's uniqueness as a motivational construct as related “other-regarding” concepts show sizeable genetic components. Finally, our results corroborate that PSM is a human resource with dynamic properties organizations can cultivate to enhance productivity in public service workforces.     

Effect of integrated treatment on the use of coercive measures in first-episode schizophrenia-spectrum disorder. A randomized clinical trial

The effect of integrated treatment on the use of coercive measures in first-episode schizophrenia-spectrum disorder in Denmark is not known. A total of 328 patients were randomly assigned to integrated treatment (167 patients) or standard treatment (161 patients). Integrated treatment consisted of assertive community treatment, psycho-educational multi-family groups, and social skills training. Data on coercion were extracted from the register from the National Board of Health, and data on continuity from medical records. Even though the level of continuity seemed higher in integrated treatment, this did not reduce the use of coercive measures compared to the use in standard treatment.     

Legal aspects of sexual violence--does forensic evidence make a difference?

A survey was done of 307 alleged victims of sexual violence reported to the police departments in Greater Aarhus, Denmark, in 1999-2004. The legal disposition was ascertained and related to victim and assault characteristics together with the forensic medical and laboratory findings. The police pressed charges in more than half of the cases and 11% turned out to be false allegations. Nineteen percent of all cases ended with sentencing of the defendant. Sperm was detected in 35% of the examined and analysed cases, and in 46% consumption of alcohol prior to the assault was reported. Information in the forensic report regarding injury documentation, intoxication, and detection of sperm and DNA match between victim and alleged assailant did not aid in the prosecution of the case. Severe coercion used by the assailant increased the likelihood of conviction. Intoxication estimation and sperm detection suffered from low sensitivity compared with laboratory analyses. Results suggest the need for new research and optimising the sexual assault examination protocol to strengthen the legal impact of forensic evidence.     

Pervasive developmental disorders and criminal behaviour: a case control study

The prevalence and pattern of criminal behaviour in a population of 313 former child psychiatric in-patients with pervasive developmental disorders were studied. The patients were divided into three subgroups and compared with 933 matched controls from the general population. Age at follow-up was between 25 years and 59 years. An account of convictions in the nationwide Danish Register of Criminality was used as a measure of criminal behaviour. Among 113 cases with childhood autism, .9% had been convicted. In atypical autism (n=86) and Asperger's syndrome (n=114) the percentages were 8.1% and 18.4%, respectively. The corresponding rate of convictions in the comparison groups was 18.9%, 14.7%, and 19.6% respectively. Particular attention is given to arson in Asperger's syndrome (p= .0009).     

Sudden death due to congenital pericardial defect: an autopsy case

Pericardial defects are rare in childhood and outcome is usually benign. Patients may be asymptomatic, but chest pain, emboli, arrhythmia, and sudden death have been described in the literature. We report the case of a 12-year-old boy who suddenly died after mild exercise. A left-sided pericardial defect with a diameter of 8 cm was detected on medico-legal autopsy.     

A new system for computer aided dental identification in mass disasters

In recent years, several computer programs for dental identification in mass disasters have been developed. Unfortunately, it may be difficult to get access to such programs. The Norwegian police presently utilizes a text retrieval program, NOVA¹STATUS, for detection work. This program is based on the British STATUS ONE program, and it enables the user to find from a large pool of postmortem dental registration one or several sets containing specific information about one tooth or several teeth. The complete relevant set(s) can be displayed for visual examination and comparison. A coding system for dental information has been developed as well as a system for interrogating the computer. This system and its efficiency have been tested on a simulated small scale disaster where various well-known difficulties in dental identification were included.     

Exclusive Safeguards and Technology Transfer: Subcontracting Agreements in Eastern Europe's Car Component Industry

We study the rationale for the use of exclusivity to protect transfer of technology in subcontracting agreements. The legal possibility arises through the EU Notice on Subcontracting. Empirically, the link between exclusive agreements and technology transfer among firms in the automotive supply industry in EU candidate countries is surprisingly weak, although with exclusive-supply or exclusive-buying clauses in subcontracting agreements upstream transfer of technology is more likely. Exclusive agreements are often reciprocal, and are typically passed on. Downstream firms are more likely to face and use vertical restraints. Technology trickles upstream: Multinational final assemblers transfer more technology than lower-tier suppliers.
