On the basis of the data contained in the European Sourcebook, this article tries to answer the question: 'What influences the prisoner rate most? The number of entries into prison, the length of sentences, or the crime rate?' The authors show that the crime rate is absolutely not correlated with the prisoner rate. The latter depends principally on the length of the imposed custodial sanctions and secondly on the number of those imposed prison sentences. Nevertheless, there are some indications suggesting that these results could be different from one type of offence to another. Unfortunately, this hypothesis could not be tested on the basis of the European Sourcebook data.  相似文献

Shaken baby syndrome (SBS), one of the most deadly and devastating forms of child abuse, is caused by violent shaking. The combination of subdural hematoma, retinal hemorrhage, brain swelling, and diffuse axonal injury is highly typical of this syndrome and faced with these autopsy findings, induced traumatic lesions are strongly considered. However, it is known that motor-vehicle accidents and falls from great height can also produce this pattern of injury. Nevertheless, stories of arms fall, couch fall, or bumped head while the baby is being carried are generally considered incompatible with SBS. We here report a case of a 2-year-old boy presenting with all the classic autopsy findings of SBS from a playground rocking toy shaken by an older child.  相似文献

The exposition to heavy metal-rich airborne due to fire practicing has forced to the development of heavy metal-free environmental ammunition primers all over the world. Here we characterize the GSR elements present in the Brazilian lead-free ammunition produced by Companhia Brasileira de Cartuchos (CBC) and commercialized by MagTech in the U.S. and Europe under the name CleanRange centerfire cartridges. Both first and second generations of CleanRange in calibers 9 mm Luger, .40 S&W, .380 AUTO and .38 SPL were analyzed and compared to regular Brazilian CBC ammunition by scanning electron microscopy/energy dispersive spectroscopy. Differences in composition and morphology of GSR particles from the two generations of CleanRange were observed. The first generation ammunition (found in Europe) presented spherical particles, being strontium the only unique element detected. The second generation (found in the U.S.) produced irregular particles composed mostly by potassium, aluminum, silicon and calcium. We can conclude that identification of GSR derived from CBC second generation lead-free ammunition in suspects' hands may be impossible without the addition of a distinct metallic taggant in the primer composition by the manufacturer.  相似文献

Abstract The paper offers a macroscopic view of the legislative electoral formulas in force in 166 sovereign countries, whether democratic or not. The purpose is to determine which formulas are the most widespread, and whether the prevalence of a formula is correlated with geographical, historical, economic, and political factors. While plurality and PR systems are equally frequent, the former tend to be found in more populated countries. PR prevails in Europe and South America, and among the most democratic countries, while the plurality rule is more typical of Asia, Africa, and North America, and is especially popular among former British colonies. Large countries are more likely to opt for single–member districts. No significant correlation emerges between the level of economic development or French colonial background and any electoral formula. The study suggests that the selection of an electoral system is not merely the outcome of party interest, but is also strongly influenced by ideas about what is good, just, or efficient.  相似文献

Turnout in electoral democracies   总被引:1,自引:0,他引:1  
Abstract. We examine turnout in 324 democratic national lower house elections held in 91 countries, between 1972 and 1995. We rely on Freedom House ratings of political rights to determine whether an election is democratic or not. We distinguish three blocs of factors that affect turnout: the socio–economic environment, institutions, and party systems. We show that turnout is influenced by a great number of factors and that the patterns that have been shown to prevail in studies dealing with more limited samples of countries generally hold when we look at a larger set of democracies. But we also show that the socioeconomic environment, which has been downplayed in previous studies, has a substantial impact on turnout.  相似文献

This paper investigates whether national elections in Europegenerate political cycles in other European countries, and, ifso, whether these spillover effects are likely to surviveinside EMU. The paper first tests whether elections in Germanyaffect macroeconomic outcomes in other European countries andthen investigates the impact of elections on budget deficits.The results indicate that German politics significantlyimpacts macroeconomic variables in other European countries,and also that politics significantly affects the behaviour ofEuropean budgetary policy. The prospect of elections tends toincrease public deficits in recessions, whereas left-winggovernments tend to be more deficit-prone than right-winggovernments regardless of the state of the economy. Moreover,the existence of political cycles spillovers among Europeancountries suggest that there may be a need for electoralcoordination.  相似文献

In criminal activities, soil can be transferred from a crime scene to items linked with a perpetrator; for example, shoes, cars or tools. Several parameters will influence the quantity of soil transferred in a given scenario. The knowledge of the most influential factors can help the expert to assess the evidence using a logical approach at the activity level or to predict the amount of soil that can be expected in a given scenario. The influence of five chosen parameters, namely the shoe profile, shoe size, walker's weight, soil type and soil humidity were assessed using Design of Experiment (DOE) in order to understand their influence on soil quantity transferred on shoes.The Faced Central Composite Design (FCCD) using a quadratic model was found to be highly significant, thus they could be adequately used to model and to interpret the amount of soil recovered from one shoe.These designs demonstrate that the characteristics of the donor (soil type and soil humidity), as well as a combination of these two factors have a very significant impact on the soil transfer. The characteristics of the receptor (shoe profile, shoe size and walker's weight) also have an impact on the transfer but to a lesser extent.Globally, this research provides valuable information for the forensic scientist both in investigative mode: evaluation of the soil quantity possibly transferred on shoes, and in the evaluative steps: is the quantity of soil found on the suspect shoes in accordance to the proposition/scenario given by the prosecution and the defence?  相似文献
