The most popular handgun in Brazil is the single round-barrel caliber 0.38 revolver. In recent years, however, owing to the modernization of police arms and their availability on the legal and illicit markets, pistols have become increasingly popular and currently represent about 20% of police seizures. In a previous paper we presented a novel collection method for gunshot residues (GSR) using a sampling procedure based on ethylenediamine-tetraacetic acid (EDTA) solution as a complexing agent on moistened swabs with subsequent detection using sector field-high resolution-inductively coupled plasma-mass spectrometry (SF-HR-ICP-MS). In the present paper, we discuss the capability of this methodology to identify antimony (Sb), barium (Ba) and lead (Pb) on the hands of volunteers after shot tests with 9 mm and 0.40 in. caliber pistols. Two types of munitions were tested: 9 mm Taurus and clean range. The use of a technique with high sensitivity, such as SF-HR-ICP-MS, permits the identification of low concentrations (less than 1 microg/L) of metals in firearm residue and constitutes a powerful tool in forensic science. We also discuss the importance of the sampling procedure, including collection from a different body part than the gun hand of the suspect. Comparison of the analytical data obtained allows clear discrimination between samples from the hands of shooters and non-shooters. 相似文献

During a three year period, 418 victims of intimate partner violence (IPV) were examined and their injuries documented at the Center for Victims of Violence (CVV) in Hamburg, Germany. All victims were questioned if their acute injuries were attributable to recurring acts of violence by the same intimate partner. The victims' experiences with recurring IPV were analyzed and associated risk factors as well as findings of acute physical injuries were integrated into the assesment. Overall, women were significantly more often victims of recurring episodes of IPV than men. In 35.4% of cases, victims of recurring IPV sustained injuries to three or more body regions. However, women who were victimized during a single act of violence, presented with the same distribution of injuries in only 21.1% of cases (p = 0.01). The results emphasize the fact that IPV often manifests itself in a spiraling escalation of physical violence. Furthermore, blunt force trauma to the head was diagnosed significantly more often (p = 0.05). The risk of sustaining a head injury was equally high for women who experienced a first-time violent episode by their ex-partner as it was for married women or women living in a non-marital partnership during recurring episodes of IPV. In an effort to reduce the increased risk for victims of IPV, health care personnel are highly encouraged to partake in forensic medicine based continuing education. This preventative measure may prepare clinicians to recognize IPV earlier as well as to treat and advise clients appropriately. 相似文献

In response to recent and past medical malpractice insurance crises, most states have implemented reforms meant to stabilize premiums and coverage availability. The importance of understanding whether these reforms implicitly affect the behavior and incentives of plaintiffs, attorneys, medical providers, and malpractice insurers in the intended way is crucial to policy makers, if they are to achieve their goal. This study specifically examines the effect of reforms on the claims defense efforts of insurers, given that defense expenses account for approximately 30 percent of malpractice premiums. Using state data for the period 1998-2002, we regress claims defense expenses against a variety of reform variables. These include seven tort reforms (noneconomic damage caps, punitive damage limits, attorney fee limits, modified collateral source rule, modified joint and several liability doctrine, mandatory pretrial screening, and statute of limitations) and two government-sponsored insurance mechanisms (joint underwriting associations and patient compensation funds). Claims defense expenses are found to be higher in the presence of noneconomic damage caps, punitive damage limits, and attorney fee limits--an unintended and counterproductive effect of reform--but are lower with mandatory pretrial screening and patient compensation funds. 相似文献

In the analysis of road accidents two types of calculation result uncertainty can be distinguished: modelling uncertainty and uncertainty in calculation results [R.M. Brach, M. Brach, Vehicle Accident Analysis & Reconstruction Methods, SAE International Publisher, Warrendale, 2005]. The problem becomes very important first of all when minor modifications of input parameters or application of different models of the phenomenon lead to a fundamentally different answer to the question posed by the court. The aim of the paper was to prove the necessity of including the problem of uncertainty in calculations related to vehicle collision mechanics and to justify the application of different error analysis methods recommendable in vehicle collision reconstruction. The data file from crash test No. 7 [H. Burg, M. Lindenmann, Unfallversuche, Verlag Information Ambs, Kippenheim, 1982] was used, the selection restricted to the range typical of average police records of collision place. Collision speeds were calculated using two methods: reconstruction and simulation. The analysis of uncertainty was carried out. Maximum and mean square uncertainty were calculated by means of total differential of relevant forms. Since the reconstruction resulted in very broad error intervals of uniform distribution, additional calculations were performed by the Monte Carlo method using algorithm described in [W. Wach, J. Unarski, Determination of vehicle velocities and collision location by means of Monte Carlo simulation method, Special Publication Accident Reconstruction SP-1999, SAE Paper No. 2006-01-0907, 2006]. 相似文献

4‐bromo‐2,5‐dimethoxyphenethylamine (2C‐B) is a designer drug. In Europe, 2C‐B is easily obtained and used for recreational purposes. It is known for its stimulating effects similar to those of 3,4‐methylenedioxymethamphetamine, although in higher doses it has more hallucinogenic effects. Here, we report a case of 2C‐B ingestion, confirmed by liquid chromatography‐tandem mass spectrometry, in an 18‐year‐old man. The neurological consequences were severe, including the development of serotonin syndrome and severe brain edema. Supportive therapy resulted in a stable condition, although, after several months, the patient still suffered from severe neurological impairment due to the drug‐induced toxicity. This case showed that 2C‐B could not be identified with the drugs of abuse screening routinely used in Dutch hospitals. The use of 2C‐B carries many risks, with potentially profound neurological damage, that both consumers and healthcare physicians are unaware of. 相似文献

This study aimed to evaluate whether the elapsed time after release to first re-offense is longer for those who complete coerced forensic addiction treatment than for those who fail to complete the treatment. It is also aimed to identify predictors of re-offending for both those who complete such treatments as compared with those who do not. Two hundred and sixty-one patients discharged from five German forensic addiction clinics were investigated on 65 anamnestic, socio-demographic, and therapeutic process variables. One hundred and fifty-one patients were prematurely discharged and returned to prison (group A; time at risk [TAR] = 58.7 months), 110 finished treatment successfully (group B; TAR = 44.2 months). Federal Criminal Register data were used for follow-up. Univariate survival analyses and multivariate stepwise Cox-regression models were computed. Twelve predictors in group A revealed a four-factor model: age at admission to treatment, duration of concurrent prison sentence, number of entries in the criminal register, and attendance at prior substitution programs. The model for group B covered five out of eight predictors: regular working activities before first diagnosis of mental illness, type of main offense, (secondary) traffic offenses, outpatient rehabilitation treatments, and escapes during treatment. Successful completers of forensic addiction treatment are slower to re-offend than non-completers. 相似文献

This meta-analysis, including six studies (13 effect sizes) and 164 adolescents, examined the effectiveness of individually oriented treatment (which means that the intervention contained at least an individual component, possibly in combination with group and/or family therapy) with CBT-elements for adolescents with severe aggression problems. A large and homogeneous overall effect size was found (d = 1.139) indicating consistency across studies. The included studies examined the effect of three interventions, namely, mode deactivation therapy (MDT; four studies), stress-inoculation therapy (1), and the cell-phone program (1). This multilevel analysis demonstrated that only few individually oriented interventions have been developed and evaluated, while four of the included studies used a weak research design. Effective individually tailored interventions for youths with severe aggression problems (who are unsuitable for group treatment) are scant. There may be added value if group interventions are supplemented with more individually tailored evidence-based interventions. 相似文献

Against the background of recent developments in Hungary, the article discusses the question whether the European Union ought to play a role in protecting liberal democracy in Member States. First, it is argued that the EU has the authority to do so, both in a broad normative sense and in a narrower legal sense (though the latter is more likely to be disputed). The article then asks whether the EU has the capacity to establish a supranational militant democracy; here it is argued that at the moment both appropriate legal instruments and plausible political strategies are missing. To remedy this situation, the article proposes a new democracy watchdog, analogous to, but more powerful than, the Venice Commission. Finally, it is asked whether EU interventions would provoke a nationalist backlash. There is insufficient evidence to decide this question, but the danger of such a backlash probably tend to be overestimated. 相似文献
