The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes.  相似文献

In recent years a growing interest in gender diversity has arisen in the business context, and a significant number of research studies have analysed its effect on corporate performance. Nonetheless, these studies have not led to conclusive results, perhaps owing to the complexity of the relationship. The present work focuses on analysing two possible justifications of the contradictory effects of gender diversity on company performance: the business context and the optimum size of the female presence in decision-making bodies. The results obtained show that when working conditions and academic background are similar, women achieve better performance in sectors traditionally dominated by men. Moreover, to take the best advantage of gender diversity it is recommended that boards of directors should be balanced or have a slightly higher female presence.  相似文献

Public support for policy instruments is influenced by perceptions of how benefits and costs are distributed across various groups. We examine different carbon tax designs outlining different ways to distribute tax revenues. Using a national online sample of 1,606 US respondents, we examine support for a $20/ton carbon tax that is: (1) revenue neutral: revenue is returned to citizens via tax cuts; (2) compensation-focused: revenue is directed to helping actors disproportionately hurt by the tax; (3) mitigation-focused: revenue funds projects reducing carbon emissions; and (4) adaptation-focused: revenue is directed to enhancing community resilience to extreme weather events. We find devoting revenue to mitigation raises overall support for carbon tax by 6.3 per cent versus the control (54.9 per cent) where no information on spending is provided. Other frames raise support in specific subgroups only. Revenue neutrality raises support among lower-income households (+6.6 per cent) and political independents (+9.4 per cent), while compensation increases support among lower-income repondents (+6.1 per cent).  相似文献

ABSTRACT

The paper deals with the issue of overpricing of public procurement in low-performing EU countries. It examines a uniquely large sample of public procurement in 11 Central and Eastern European countries. Hierarchical regression is used to analyze the factors that influence public contract. Our results indicate that institutional factors have a greater impact on overpricing than individual decisions by the contracting authority. Our analysis for low-performing EU countries provides interesting results and also draws attention to behavior that is not typical of the better established and more advanced EU countries. Our results are particularly important for public policy in each country, as they show the direction of regulatory action in the field of public procurement. The results introduce a debate on the appropriateness of “one size fits all” regulations within the EU.  相似文献

Most chemical and physical methods employed in visualizing latent marks have shown detrimental effects on human health and, therefore, some research groups have directed their attention to the utilization of various (bio)polymers with the aforementioned purpose. Although chitosan is widely used in medicine, pharmacy, food, and drug delivery systems, there are very few studies that address this biopolymer utilization in forensic applications, such as the detection of latent fingerprints. We used chitosan crosslinked with sodium tripolyphosphate and conjugated with L‐lysine to enhance the visualization of latent fingerprints, due to its ability to interact with fingerprint sweat residues. These conjugates were prepared using different (w/w) amounts of chitosan and tripolyphosphate (6/1; 4/1; 1/1; 1/4; and 1/6), and those with the most promising results (i.e., 6/1 formulation) were investigated in detail. Fourier transform infrared (FT‐IR) spectroscopy confirmed interactions between components of the systems. Optical microscopy and scanning electron microscope (SEM) analysis showed that prepared powder formulations were uniform in size and confirmed that chitosan/tripolyphosphate/lysine conjugates bind easily to the sweat and lipid residues present in the latent fingerprints. The testing of prepared conjugates demonstrated the potential of these systems as bio‐based powder substitution for commercially available powders.  相似文献

By discussing the role of the Balkan Entente within Turkish–Yugoslav relations, this article endeavours to reflect the extent to which the Entente guaranteed security to Turkey and Yugoslavia. It deals with the 1934–41 period, which starts with the formation of the Balkan Entente and ends with the German invasion of Yugoslavia. The article is written mainly based on Yugoslav archival documents and aims to provide an alternative narrative that contests the conventional Turkish view. It also demonstrates that although the political leaders in Turkey and Yugoslavia became more optimistic about the future of the region after having signed the Balkan Entente, their perception of threat changed over time during the period of increasing instability in Europe.  相似文献
