Adolescent homicides in Finland: offence and offender characteristics

Approximately 9% of the homicides in Finland are committed by adolescents under 20 years of age. The purpose of this study was to investigate the offence and offender characteristics in homicidal adolescents. Forensic psychiatric evaluation statements of adolescent offenders accused of a homicide during 1990-2001 were reviewed retrospectively (n=57). In 38% of the cases, there were multiple offenders. In 58% of the cases, the victim was an acquaintance, in 25% a stranger, in 12% a family member and in 5% of the cases an (ex)intimate partner. Sixty-nine percent of the offenders were intoxicated and 21% under the influence of drugs at the time of the killing. The most frequent motives were an argument (25%) and a robbery (25%). Sixty-four percent of the offenders had developmental problems and 42% had a crime history. Approximately half were diagnosed as having a conduct or a personality disorder, but 32% of the offenders were considered not to suffer from a mental illness or substance abuse. For 63%, the level of intellectual functioning was average or above average. There were signs of more than one form of violence in 54% of the cases and 28% of the cases contained excessive violence. The use of multiple and excessive violence was significantly related to the offender age, multiple offenders, offender-victim relationship and substance abuse, but not related to having developmental problems, crime history or mental illness.     

Reform, change, and continuity in Finnish health care

This article describes some essential aspects of the Finnish political and governmental system and the evolution of the basic institutional elements of the health care system. We examine the developments that gave rise to a series of health care reforms and reform proposals in the late 1980s and early 1990s and relate them to changes in health care expenditure, structure, and performance. Finally, we discuss the relationship between policy changes, reforms, and health system changes and the strength of neo-institutional theory in explaining both continuity and change. Much of the change in Finnish health care can be explained by institutional path dependency. The tradition of strong but small local authorities and the lack of legitimate democratic regional authorities as well as the coexistence of a dominant Beveridge-style health system with a marginal Bismarckian element explain the specific path of Finnish health care reform. Public responsibility for health care has been decentralized to smaller local authorities (known as municipalities) more than in any other country. Even an exceptionally deep economic recession in the early 1990s did not lead to systems change; rather, the economic imperative was met by the traditional centralized policy pattern. Some of the developments of the 1990s are, however, difficult to explain by institutional theory. Thus, there is a need for testing alternative theories as well.     

The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives

This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to identify possible sources of errors that could arise during the analysis and interpretation of mtDNA profiles. These findings were taken as a basis to tentatively make suitable arrangements for the construction of a high quality mtDNA database. One hundred fifty mtDNA profiles were submitted to the evaluating laboratory, and disaccording profiles were classified into four groups corresponding to the source of error: clerical errors, sample mix-ups, contaminations and discrepancies with respect to the mtDNA nomenclature. Overall, 14 disaccording haplotypes (16 individual errors) were observed. The errors included 10 clerical errors, 3 interpretation problems, 2 cases of sample mix-up and 1 case of point heteroplasmic mixture, where the 2 sequencing reactions brought inconsistent base calls. This corresponds to an error rate of 10.7% in a virtual mtDNA database consisting of the collaborative exercise results. However, this estimate is still conservative compared to conclusions drawn by authors of meanwhile numerous publications critically reviewing published mtDNA population databases. Our results and earlier published concerns strongly emphasize the need for appropriate safety regulations when mtDNA profiles are compiled for database purposes in order to accomplish the high standard required for mtDNA databases that are used in the forensic context.     

Comparison of ethyl glucuronide and fatty acid ethyl ester concentrations in hair of alcoholics, social drinkers and teetotallers

In previous investigations hair analysis for ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEE) proved to be suitable for the detection of excessive alcohol consumption. The aim of this study was to compare EtG and FAEE concentrations in hair of alcoholics, social drinkers and teetotallers. Hair samples from 10 alcoholics in withdrawal treatment, 11 fatalities with documented excessive alcohol consumption, four moderate social drinkers who consumed up to 20 g ethanol per day, and three strict teetotallers were analysed. After external degreasing with n-heptane, extraction with a dimethyl sulfoxide/n-heptane mixture and headspace solid-phase microextraction of the extracts, four fatty acid ethyl esters (FAEEs) (ethyl myristate, ethyl palmitate, ethyl oleate and ethyl stearate) were analysed by gas chromatography-mass spectrometry (GC-MS) with deuterated internal standards. EtG was determined by GC-MS/NCI after ultrasonication of the samples with H2O, cleanup by SPE with aminopropyl columns and PFP derivatisation. The following concentrations were measured for the four groups: teetotallers EtG < 0.002 ng/mg, FAEE 0.05-0.37 ng/mg, moderate social drinkers EtG < 0.002 ng/mg, FAEE 0.26-0.50 ng/mg, alcoholic patients EtG 0.030-0.415 ng/mg, FAEE 0.65-20.50 ng/mg and the fatalities with alcohol history EtG 0.072-3.380 ng/mg, FAEE 1.30-30.60 ng/mg. The results confirm that by using a cut-off value of the sum of FAEE > 1 ng/mg and/or a positive EtG result in hair, excessive alcohol consumption can be identified using hair analysis. However, no significant correlation between the EtG and FAEE concentrations in the positive cases could be shown. Segmental analysis of some of the specimens did not reveal the same distribution for EtG compared to FAEE in hair, and no chronological accordance compared to the self-reported alcohol consumption could be observed for both parameters. These different results of both methods are discussed in terms of differences between EtG and FAEE in mechanism of formation and incorporation into hair and elimination from hair.     

STR polymorphism among two tribal populations of India

Two tribal populations of India, Bison Horn Maria and Muria from Bastar district of Madhya Pradesh in Central India were studied for DNA polymorphisms at tetranucleotide short tandem repeat (STR) loci (F13A01 and HUMvWA). A total of 63 random adult individuals for F13A01 locus and 53 samples for HUMvWA were analyzed in the present study.     

Cause-of-death query in validation of death certification by expert panel; effects on mortality statistics in Finland, 1995

The correctness of selection, coding and registration of underlying cause-of-death is important for the quality of mortality statistics. One measure to improve quality is the query to the certifier for verification of the underlying cause-of-death. In Finland, 3478 death certificates, 7.1% of total 49074 certifications in 1995, were considered questionable by statisticians. The expert panel at Statistics Finland was able to resolve 2813 (80.9%) of them. However, 665 (19.1%) certificates needed to be further queried from the certifier. Of these, 318 (47.8%) were re-assigned to another ICD-9 category or to the applicable three-digit category within the main category of heart and vascular diseases, resulting in changes from a 17.00-fold increase in rheumatic heart diseases (ICD-9 codes 390-398) to a decrease of about one-half (0.45-fold change) in unspecified neoplasms (codes 235-239). However, a statistically significant impact on national mortality statistics was not observed in any of applied ICD categories. Among all questionable death certificates, most prone to query of the certifier, and with a statistical significance of P<0.05, were those with no cause-of-death specified, those stating underlying cause-of-death as non-specified neoplasms (with a observed/expected ratio, O/E, of 1.69), and heart and vascular diseases (1.45), with its subcategories of ischaemic heart diseases (1.33) and other heart diseases (2.92). Death certificate validation, by expert panel consultations and query to the certifiers, and the importance of estimation of the validity of cause-of-death information on death certificates are strongly pointed out in a continuous strive for correct and reliable mortality statistics.     

Methadone and its role in drug-related fatalities in Cologne 1989-2000

All drug-associated deaths from 1989 to 2000 were analysed at the Institute of Forensic Medicine in Cologne. Information concerning sex, gender, drug consumption, time, place and circumstances of death were analysed. A number of 605 cases were recorded; in 518 cases a toxicological analysis was possible and in 171 an autopsy was performed. When it was possible to determine the cause of death form the information available, acute drug intoxication was recorded in 65%. Heroin head the list of identified substances. Sixty-three percent of the specimens showed a combination of several substances, especially a combination of morphine, benzodiazepines, other medications and alcohol. In comparison with other studies the percentage of methadone-positive specimens is low, even though the proportion of specimens positive for methadone increased from 1989 to 2000. This analysis is discussed using background information concerning the management of substitution therapy and the available literature.     

The checks and balances of party federalism: German federal government in a divided legislature

Abstract In this study, we assess the potential for policy change of the German government of Helmut Kohl after unification combining party positions with formal bicameral settings in a spatial model of legislative action. We distinguish between two policy areas and two types of legislation, mandatory and non–mandatory legislation imposing either a symmetric or asymmetric power distribution between both German chambers. In order to identify German legislators' party positions in different policy areas, we use data from ECPR Party Manifesto research covering the period from German unification in 1990 to the end of the government of Helmut Kohl in 1998. We find that the federal government of Helmut Kohl had a policy leadership position until April 1991 with no procedural differences, but the gridlock danger for governmental proposals was higher on the societal than the economic dimension. Afterwards, the government's potential for policy change was considerably determined by the type of legislation, independently from the policy dimension. At the end of the Kohl era, the governmental policy leadership position was limited to policies that left even the opposition majority of German states better off. The procedural settings mattered greatly on the economic dimension, and the danger of gridlock on societal policy was smaller only for non–mandatory legislation.     

Supercritical fluid chromatography in forensic science: a critical appraisal

The application of supercritical fluid chromatography (SFC) in forensic science is reviewed. The applications centre on the analysis of explosives and of drugs of abuse. The systems employed are discussed in the context of comparison with gas chromatography and high-performance liquid chromatography methods which are traditionally used for such analyses. The advantages and disadvantages of SFC over these methods are discussed. Recommendations are made for the developments which are required in SFC technology if it is to find greater application in forensic science.
