Demands on scientific studies in different fields of forensic medicine and forensic sciences. Traffic medicine--impaired driver: alcohol, drugs, diseases

Since human performance is a key factor in crash causation detailed knowledge of the involvement of alcohol, drugs and diseases is of fundamental interest for road safety. To better understand the effect of these influencing factors it is important to use a combination of witness observations and a range of experimental and epidemiological studies. Epidemiological approaches to research such as road-side-surveys, case-control-studies, culpability analysis, pharmaco-epidemiological studies are usually seen as being able to provide the best answers. This article discusses the relative merits of experimental and epidemiological approaches.     

The 2015 Norwegian Local Elections: Support for Governing Radical Right Progress Party Plummets and Great Gains for Greens in ‘Second-Order’ Elections

Two years into the first term of the right wing Conservative/Progress Party coalition government, the 2015 Norwegian local elections displayed many features of a ‘second-order’ election: the governing parties lost considerable support, minor parties did well and voter turnout was low. For the second local elections in a row, political circumstances prevented the far right Progress Party from mobilizing on the anti-immigration issue, adding to the burdens of governing nationally for the first time. The Green Party leveraged its 2013 entry into the national parliament into record support, consolidating the progress made in the 2011 local elections. Although the elections were shaped by national politics, municipal and county variation shows that local political factors did matter.     

Unregistered residents and registered crime: an estimate for asylum seekers and irregular migrants in Norway

The purpose of our study has been to better estimate the number and types of crimes committed by asylum seekers and irregular migrants. While data on immigration status for non-residents are lacking in Norwegian crime statistics, we use indirect identifiers (lack of a national ID number, citizenship, residency) to arrive at an estimate for persons with a pending asylum claim and the related group of irregular migrants (i.e. non-EU citizens). A very small amount of the total crimes registered with a known offender are committed by this group. However, these groups are most likely overrepresented as offenders compared to the registered resident population, also when taking age and gender into consideration. Our method is recommended in a field otherwise dominated by political arguments and as an alternative to registering asylum status in crime registers.     

Higher Education as an Arena for Political Socialisation: Myth or Reality?

Political values and voting behaviour differ significantly between employees in the public and the private sectors, to the extent that some have called this one of the most important political cleavages in modern societies. But what causes these differences? The article outlines two hypotheses, one being the possibility that political values are shaped during higher education. To try and shed some light on this hypothesis, the political values of two groups of students at Agder University College in southern Norway were studied over a period of time. One group of students studied disciplines – nursing, social work, and teaching – that would almost without exception give them jobs in the public sector. The other group studied economics, a subject that for most of them would lead to a job in the private sector. Their political values were then measured at two points in time: when beginning study and after three years of studying. The main conclusion is that political values differ when the students begin to study, and that most political values change only marginally during the three‐year period. The few changes that occur during the period hint at a minor tendency for students to become more politically alike, indicating that higher education has a slight homogenising effect on political values. For one type of political values, however, rather dramatic changes take place. Both student groups acquire significantly more non‐authoritarian values during studies, indicating that higher education may be an important cause of such values.     

Age estimation and the developing third molar tooth: an analysis of an Australian population using computed tomography

The third molar tooth is one of the few anatomical sites available for age estimation of unknown age individuals in the late adolescent years. Computed tomography (CT) images were assessed in an Australian population aged from 15 to 25 years for development trends, particularly concerning age estimation at the child/adult transition point of 18 years. The CT images were also compared to conventional radiographs to assess the developmental scoring agreement between the two and it was found that agreement of Demirjian scores between the two imaging modalities was excellent. The relatively wide age ranges (mean ± 2SD) indicate that the third molar is not a precise tool for age estimation (age ranges of 3-8 years) but is, however, a useful tool for discriminating the adult/child transition age of 18 years. In the current study 100% of females and 96% of males with completed roots were over 18 years of age.     

New designer drug of abuse: 3,4-Methylenedioxypyrovalerone (MDPV). Findings from apprehended drivers in Finland

Starting in 2008 a new designer drug, 3,4-methylenedioxypyrovalerone (MDPV) appeared among users of illegal drugs in Finland. Since then there have been several seizures of MDPV by police and customs and it has been connected to many crimes of different types. In this study the incidence and impact of the use of MDPV in drivers suspected of being under the influence of drugs (DUID) in Finland was assessed. Since autumn 2009, blood samples from drivers suspected of DUID in Finland have been analysed for the presence of MDPV. A new LC-MS/MS method for the determination of MDPV in serum was established. In order to assess the impact of MDPV on driving performance, drug and alcohol findings of positive MDPV cases were compared with data from the clinical examination carried out while the suspect was under arrest. In a period of one year there were 259 positive MDPV cases from apprehended drivers (5.7% of all confirmed DUID cases). In 80% of the cases in which MDPV was found, amphetamine was also present. Benzodiazepines were also frequently found together with MDPV, which was to be expected since in Finland, in our experience, stimulants are very often used together with benzodiazepines. In most cases it remained unclear whether the observed psycho-physical achievement deficiency was induced by MDPV because the concentrations of other drugs, especially other stimulants, were often high. However, in some subjects, MDPV, or MDPV in combination with other substances was the most probable cause of the impairment. The concentrations of MDPV varied from 0.016mg/L to over 8.000mg/L. Little is known about the pharmacology of MDPV. However, based on our findings it is clear that MDPV has a serious impact on traffic safety in Finland.     

Carbon monoxide concentrations in the 2009 Victorian Bushfire disaster victims

Blood was available for the estimation of carboxyhemoglobin saturation (COHb) in 30 of the 173 persons who died in the Victorian bushfires in February 2009. The ages of these 30 deaths ranged from 3 to 80 years and there were 8 females. 13 cases (43%) were considered negative (less than 5% COHb), 12 (40%) were between 5 and 40% COHb, 2 (6.7%) between 40 and 50% and 3 (10%) were greater than 50% COHb. There were 6 persons either found within a building or a car and the COHb in these cases ranged up to 69% (mean 50%). There were 5 cases where the location was unable to be determined as either indoor or outdoor due to the extensive nature of the fire. The remaining 19 deceased persons were all located outside in the open and the concentration of COHb in these cases ranged up to 30% (mean 19%). Hydrogen cyanide was only detected in two deceased persons at concentrations of 0.5 and 2.7 mg/L, respectively. 13 deceased were found to have soot in the airways following necropsy but this did not correlate with the COHb levels.
