We use data from Italian local level governments for the years 1985?C2008 to investigate whether political competition affects the quality of politicians, as measured by some ex-ante characteristics such as educational level and type of job held. We handle endogeneity problems through an instrumental variable approach using as an instrument for political competition a variable taking into account whether the previous Municipal Council survived until the end of its legislative term. Two Stage Least Square estimates support the view that political competition positively affects politician quality. Results are robust to different measures of political competition and to different estimation strategies. 相似文献

Genotype and allele frequencies for STR loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820 were investigated in 289 unrelated Italian Caucasian individuals from the North and South regions. After co-amplification by polymerase chain reaction, automatic DNA profiling of these nine STR loci was performed by ABI PRISM((R)) 310 DNA Genetic Analyzer. For each locus, statistical parameters for forensic and paternity purposes were then calculated; the combined power of discrimination and the combined power of exclusion of all nine loci were 0.9999999999917 and 0.99992 for the Northern population and 0.9999999999921 and 0.99991 for the Southern population. 相似文献

A fatal suicidal ingestion of drugs, together with activated charcoal, is reported. The death occurred 31 hours after the self-administration. The autopsy revealed a large amount of gastric content that appeared to be a compact mass of black color. Toxicologic analyses showed the presence of toxic levels of desalkylflurazepam and trazodone; metamizole and pridinol were also detected. The obtained results supported the hypothesis of a death due to acute intoxication delayed by the self-administration of activated charcoal, which elimination was probably hindered by the action of pridinol. 相似文献

There has been relatively little change over recent decades in the methods used in research on self-reported delinquency.
Face-to-face interviews and self-administered interviews in the classroom are still the predominant alternatives envisaged.
New methods have been brought into the picture by recent computer technology, the Internet, and an increasing availability
of computer equipment and Internet access in schools. In the autumn of 2004, a controlled experiment was conducted with 1,203
students in Lausanne (Switzerland), where “paper-and-pencil” questionnaires were compared with computer-assisted interviews
through the Internet. The experiment included a test of two different definitions of the (same) reference period. After the
introductory question (“Did you ever...”), students were asked how many times they had done it (or experienced it), if ever,
“over the last 12 months” or “since the October 2003 vacation”. Few significant differences were found between the results
obtained by the two methods and for the two definitions of the reference period, in the answers concerning victimisation,
self-reported delinquency, drug use, failure to respond (missing data). Students were found to be more motivated to respond
through the Internet, take less time for filling out the questionnaire, and were apparently more confident of privacy, while
the school principals were less reluctant to allow classes to be interviewed through the Internet. The Internet method also
involves considerable cost reductions, which is a critical advantage if self-reported delinquency surveys are to become a
routinely applied method of evaluation, particularly so in countries with limited resources. On balance, the Internet may
be instrumental in making research on self-reported delinquency far more feasible in situations where limited resources so
far have prevented its implementation.

Abstract: Machinery‐related fatalities are one of the leading causes of traumatic occupational deaths. In our report, we present the case of a 40‐year‐old male who suffered a severe head trauma while working in a cut‐foam industry and died despite an early craniectomy. The radiological reconstruction of the skull based on preoperative computed tomography scans disclosed a large depressed conical fracture of the left parietal bone. The 3D‐reconstruction of the work area, combined with a fit‐matching analysis between the machinery and the depressed skull fracture allowed us to conclude that the head was crushed between the sliding bar of the cutting device and the metallic protuberance on the opposite side. The case underlines the importance of a detailed workplace investigation and of a thorough evaluation of all circumstantial, clinical, radiological, and autopsy data in the reconstruction of machinery‐related fatalities to identify any possible legal responsibilities of the worker and/or the employer. 相似文献

Abstract: In the present study, ultrastructural analysis of mitochondrial deposits (black dots within mitochondria) as a method for the detection of early acute myocardial infarction (AMI) was evaluated. In 24 patients with AMI and six controls, analysis was performed in the heart of infarcted patients and noninfarcted controls. In the infarction area in lactate dehydrogenase (LDH)‐diagnosed AMI, the percentage of positive mitochondria was significantly higher compared to corresponding heart tissue in control patients and compared to noninfarcted areas within these patients. Also in patients with a clinically diagnosed AMI but no LDH decoloration, a significant higher percentage of positive mitochondria was found in the left ventricle compared to controls and noninfarcted areas. In patients with AMI, an increase in mitochondria with deposits was found in the infarction area compared to controls and noninfarcted tissue within the same patient, suggesting that electron microscopical changes in mitochondria can be used for the diagnosis of AMI less than 3 h old. 相似文献

Archaeological remains can provide concrete cases, making it possible to develop, refine or validate medico-legal techniques.In the case of the so-called ‘Joan of Arc's relics’ (a group of bone and archaeological remains known as the ‘Bottle of Chinon’), 14 specialists analysed the samples such as a cadaver X of carbonised aspect: forensic anthropologist, medical examiners, pathologists, geneticists, radiologist, biochemists, palynologists, zoologist and archaeologist. Materials, methods and results of this study are presented here.This study aims to offer an exploitable methodology for the modern medico-legal cases of small quantities of human bones of carbonised aspect. 相似文献

Criminal behavior of parents substantially affects the criminal behavior of children. Little is known, however, about how
crime is transmitted from one generation to the next. In order to test two possible explanations against each other, we pose
the question whether the timing of the criminal acts of fathers is important for children’s chances of committing crime. Static
theories predict that it is the number of delinquent acts performed by fathers that is important, and that the particular
timing does not affect the child’s chance of committing crime. Dynamic theories state that the timing is important, and children
have a greater chance of committing crime in the period after fathers have committed delinquent acts. Results show that the
total number of convictions of a father is indeed very important, but also the exact timing is key to understanding intergenerational
transmission of crime. In the year a father is convicted the chance his child is also convicted increases substantially and
it decays in subsequent years. This decay takes longer the more crimes father has committed. Our results show that some of
the assumptions of the static theories at least need to be adjusted. 相似文献

The entry into force of the Lisbon Treaty has suspended discussions over the release of a EU PNR processing system. Plans to introduce an intra-EU PNR processing system initiated since 2007, although strongly supported by the Commission and the Council, did not bear fruit before the ratification of the Lisbon Treaty and the, institutional, involvement of the Parliament. While discussions have been suspended since October 2009 and most probably a new draft proposal will be produced, it is perhaps useful to present in brief the proposal currently in place so as to highlight its shortcomings for European data protection and suggest ways individual protection may be strengthened in future drafts. 相似文献
