The body of a 30‐year‐old woman was found in Como lake at a depth of about 120 meters in her own car after 3 years of immersion. The aim of this study was to evaluate psychoactive drugs as well as alcohol biomarkers in biological matrices. The following analyses were initially performed: GC‐MS systematic toxicological analysis on biological fluids and tissues; GC‐MS analysis of drugs of abuse on pubic hair; direct ethanol metabolite determination in pubic hair by LC‐MS/MS. After 7 years, the samples, that had been stored at ?20°C, were re‐analyzed and submitted to an LC‐MS/MS targeted screening method, using multiple reaction monitoring mode. These analyses detected citalopram (150–3000 ng/mL), desmethylcitalopram (50–2300 ng/mL), clotiapine (20–65 ng/mL), and ethyl glucuronide (97 pg/mg). The methods showed an acceptable reproducibility, and the concentrations of citalopram and desmethylcitalopram calculated through the two analytical techniques did not significantly differ in biological fluids. 相似文献

Dealing with burnt bodies, the forensic pathologist must first of all answer the question whether the victim was alive at the moment of the fire. This study aims at clarifying whether some human solid tissues may be reliably used for the forensic diagnosis of Co poisoning on burnt bodies providing no collectable blood during the autopsy. From 34 selected cases, both cardiac blood and parenchymal samples were collected to perform CO‐oxymeter, spectrophotometry, and gas chromatography tests: blood CO estimations (blood COHb% and blood[CO]) and parenchymal[CO] values have been compared with special focus on R values. The solid tissues having the best correlations with blood CO amount turned out to be the lung (R 0.84), the liver (R 0.83), the kidney (R 0.79), and the spleen (R 0.92). 相似文献

This paper analyzes the effect of traffic tickets on motor vehicle accidents. Ordinary least squares (OLS) estimate may be upward biased because police officers tend to focus on areas where and periods when there is heavy traffic and thus higher rates of accidents. This paper exploits the dramatic increase in tickets during the Click‐it‐or‐Ticket campaign to identify the causal impact of tickets on accidents using data from Massachusetts. I find that tickets significantly reduce accidents and nonfatal injuries. I provide suggestive evidence that tickets have a larger impact at night and on female drivers. 相似文献

Abstract Only two years after the critical elections of 27 March 1994, the Italian parliamentary election of 1996 marks another important step in the transformation of the political class. The extent of turnover is declining, and the renewal of the parliamentary elite shows some signs of stabilization. This article inquires into the differences in the sociological configuration of the new elite, and whether this means that new consolidated pathways to the parliamentary elite now already exist. The article analyzes the distribution of freshmen in the political class, the return of old backbenchers in the new political parties, the social and occupational background of MPs and, finally, their local and political experiences. In the final section, the article discusses some hypotheses about the perspectives on the recruitment of Italian MPs, focusing in particular on the effects of the structural crisis of political parties and the introduction of the plurality system. An empirically–derived typology of professionalization patterns is also provided. 相似文献

Sex assessment is one of the first essential steps in human identification, in both medico-legal cases and bio-archaeological contexts. Fragmentary human remains compromised by different types of burial or physical insults may frustrate the use of the traditional sex estimation methods, such as the analysis of the skull and pelvis. Currently, the application of discriminant functions to sex unidentified skeletal remains is steadily increasing. However, several studies have demonstrated that, due to variation in size and patterns of sexual dimorphism, discriminant functions are population-specific. In this study, in order to improve sex assessment from skeletal remains and to establish population-specific discriminant functions, the diagnostic values of the carpal bones were considered. A sample of 136 individuals (78 males, 58 females) of known sex and age was analyzed. They belong to a contemporary identified collection from the Laboratory of Physical Anthropology, Faculty of Medicine, UNAM (Universidad Nacional Autónoma de México, Mexico City). The age of the individuals ranged between 25 and 85 years. Between four and nine measurements of each carpal bone were taken. Independent t-tests confirm that all carpals are sexually dimorphic. Univariate measurements produce accuracy levels that range from 61.8% to 90.8%. Classification accuracies ranged between 81.3% and 92.3% in the multivariate stepwise discriminant analysis. In addition, intra- and inter-observer error tests were performed. These indicated that replication of measurements was satisfactory for the same observer over time and between observers. These results suggest that carpal bones can be used for assessing sex in both forensic and bio-archaeological identification procedures and that bone dimensions are population specific. 相似文献

Sex assessment is one of the first essential steps in human identification, in both medico-legal cases and bio-archaeological contexts. Fragmentary human remains compromised by different types of inhumation or physical insults may frustrate the use of the traditional sex estimation methods, such as the analysis of the skull and pelvis. Currently, the application of discriminant functions to sex unidentified skeletal remains is steadily increasing. However, several studies have demonstrated that, due to variation in size and patterns of sexual dimorphism, discriminant function equations are population-specific [1,2,5,12,61]. In this study, in order to improve sex assessment from skeletal remains and to establish population-specific discriminant functions, the diagnostic values of the carpal bones were considered. A sample of 100 individuals (50 males and 50 females) of known sex and age was analyzed. They belong to a 20th century identified collection from the Municipal Cemetery of "San José", Granada (Spain) and housed in the Laboratory of Anthropology, Faculty of Medicine, University of Granada (Spain). The age of the individuals ranged between 22 and 85 years. Between four and nine measurements of each carpal bone were performed [41,59]. Discriminant function statistics showed a sex assessment accuracy as high as 97.8%. The results suggest that carpal bones can be used for assessing sex in both forensic and bio-archaeological identification procedures. 相似文献

Building on the recent re-discovery of the Iranian Revolution, this analysis examines the policies of the Carter Administration and their effects on Iran and the Iranian opposition. Starting with Jimmy Carter's election and hopes for a new era in American–Iranian relations, there occurred the progressive creation and expansion of a rift between the Carter Administration and the Iranian opposition. This rift was exacerbated by stubborn American support for an increasingly weak Shah, and by the complete unwillingness, both in Washington and at the American Embassy in Tehran, to meet with opposition members, let alone with Ayatollah Ruhollah Khomeini. In this sense, the horizon of the analysis of the origins of the Iran hostage crisis is expanded with a longer-term perspective. The taking of the hostages represented the final act of a troubled relationship that had probably begun before Carter took office. 相似文献

Abstract Child services organisations need policies that minimise the risk of sexual abuse of the children in their care. In particular, managers (and the public) are justifiably concerned when abuse is perpetrated by individuals who should not have been working with children in the first place. Unfortunately, there has been relatively little work on determining unacceptable risk for sexually abusive behaviour in child service organisations. The purpose of this paper is to describe the contexts in which screening procedures are appropriate, review the academic literature on screening procedures and present the results of a pilot survey of current screening practices in the United Kingdom. We comment on the effectiveness of screening measures available for use by organisations and provide suggestions for improvement. Specifically, we recommend that screening procedures consider risk factors associated with the onset and persistence of child sexual abuse perpetration. 相似文献

This paper provides novel empirical evidence on productivity growth in the manufacturing sector in Chile, Colombia, Mexico and Peru. Relying on plant-level data, we first decompose productivity and productivity growth into plant-level growth and market allocation forces. While the average productivity of the survivors is higher than the overall contribution of reallocation forces, during recessions the inverse is true and reallocation gives a positive, albeit small, contribution to aggregate productivity growth. Next we analyze how policy measures can determine allocative efficiency levels and growth, and find important scope for action on education, financial regulation, and structural reforms. 相似文献
