This study deals primarily with the question of continuity in serious criminality. The study follows a cohort consisting of 15,117 individuals from the age of 15 years through the age of 30 years. The age-based transition probabilities are studied, both for males and for females, showing that the transitions for females conform to a first-order Markov chain, so that the original matrices can be seen as estimates from a single parent matrix. This was not the case for males. The predictive power of prior criminality for later transition probabilities is also studied. Finally, the difference between stating that a given percentage will relapse in crime and the ability to make real prediction is emphasized. 相似文献

Abstract: Within the framework of the ENFSI Expert Working Group "Firearms" a proficiency test on the detection and identification of GSR by energy-dispersive scanning electron microanalysis (SEM/EDX) is carried out in a 2 years term. The latest test was performed in 2005/2006 and was denoted as GSR2005 . Seventy-five laboratories from 28 countries participated in this proficiency test and submitted in total 83 independent data-sets. The participating laboratories were requested to determine the total number of PbSbBa containing particles on a synthetic test sample following their own laboratory specific methods of automated GSR particle search and detection by SEM/EDX. Furthermore size and position of the detected particles had to be reported by the laboratories and were evaluated statistically. The results were compiled by means of z -scores according to the IUPAC and EURACHEM guidelines—assessing individual laboratory achievements (inter-laboratory) as well as intra-laboratory performance—and were compared to the results of the previous proficiency test run GSR2003 ( 1 ). The comparison shows that there is a noticeable improvement in the method's detection capability. 相似文献

The frozen party hypothesis has been rejected in several contemporary studies. However, by conceptualizing the Scandinavian parties in three categories, and by focusing the study on the three pole parties originally emphasized by Stein Rokkan, the bulk of the Scandinavian party system is still frozen. Diminishing class voting and electoral instability are inefficient measures of how well cleavages structures are reflected in the party system. Cleavages must be understood in a broader context where the struggle between the three fronts to incorporate new categories of voters is the very essence of an enduring cleavage structure. 相似文献

This study on trafficking in women from Central and Eastern Europe explores the contextual factors, the characteristics, and the motivation of victims as well as the methods of traffickers. A combination of rational choice theory, strain theory and social control theory forms the theoretical framework of our research. Based on information from experts in the field, interviews with victims, questionnaires, a study of dossiers and a search of the literature, we developed a typology of victims, which may be helpful for prevention and law enforcement. 相似文献

With increasing regional disparities in economic development and living conditions in Europe, migration has become a key element in domestic politics of many European countries. One of the main concerns of analysis has been the search for important determinants of migration, however, the role of ?region specific cultural capital“ has not been considered. This omission is the starting point of our discussion and we introduce region specific capital as a form of cultural capital. In contrast to widespread approaches, hypotheses deriving from the theory of Pierre Bourdieu and his distinction of economic, social and cultural capital are deduced and empirically tested, using a representative survey of 3005 persons living in Saxony. The results show that the main determinants of migration are region specific cultural capital, dissatisfaction and age. 相似文献
