我国开征碳税的制度经济学视角分析

碳税被国际社会公认为是削减二氧化碳排放的有效的经济手段之一,目前我国正在尝试开征碳税,本文从制度经济学视角来分析碳税及其开征的必要性,尝试提出开征碳税的正式规则和非正式规则两种制度设计。     

The role of environmental factors in the causation of sudden death in infants: two cases of sudden unexpected death in two unrelated infants who were cared for by the same babysitter

We report two cases of sudden unexpected death in two unrelated African American female infants, 2 months and 4 months old. Both infants were attended to by the same babysitter in the same apartment and died 39 days apart in the same bed and in the same bedroom. The autopsy of the first infant revealed sudden unexplained death in an infant. Toxicologic analysis for carbon monoxide (CO) was not performed because it was not suspected. When the second infant died, investigation into the ambient air quality within the apartment revealed high levels of CO emanating from a poorly ventilated and defective hot water heater, which was located across a hallway from the bedroom where the two babies died. CO saturation levels in the postmortem blood samples of the two babies were elevated and were similar (13% and 14%). Nicotine and cotinine were not detected in the blood sample of the two infants. Cherry-red livor mortis was absent. Acute CO intoxication was determined to be the underlying cause of these two unexpected deaths. These two cases underscore the need to integrate ambient air analysis and postmortem CO analysis as routine components of the comprehensive death investigation of infants who die suddenly and unexpectedly.     

论“碳政治”博弈的国际法治理

围绕哥本哈根国际法进程而展开的碳政治博弈,因《哥本哈根协议》的无约束力而造成零和博弈的结果,也使未来国际法进程面临＂双轨＂抑或＂三轨＂并进的机制选择,同时,气候变化的国际法治理仍将针对＂共同但有区别责任＂的适用而展开,国际社会如能经由＂人类共同关切事项＂明确＂共同责任＂的内涵,通过实质性公平原则而认同＂区别责任＂的要旨,推动《哥本哈根协议》的落实和发展,将在＂霸权缺失＂下的＂碳政治＂博弈中,以＂软法＂特有的张力和灵活性,维护＂共同但有区别的责任＂的国际法地位,并弥合各方分歧,促进＂为今世后代保护全球气候＂的可持续发展目标的实现。     

国际“碳政治”博弈与中国的对策

作为一种新型国际政治,"碳政治"一词伴随全球变暖问题而出现,为国际政治舞台增添了新的博弈因素。需要指出的是,我们欢迎"碳政治"这一新型国际政治,但反对把国际气候问题政治化。把国际气候问题政治化、寻求实现其他目的,无助于切实解决气候变化问题给人类社会带来的挑战。     

影响我国碳金融发展的原因分析

与西方发达国家较为完善的碳金融发展相比,我国碳金融发展相对比较滞后,造成这种状况的原因主要有：一是对碳金融的认识有待深化;二是碳金融的综合配套政策不完备;三是碳金融市场分割现象严重;四是中介服务机构发育不完善。对这些原因进行深入分析,有利于排除碳金融发展的障碍,开创我国碳金融发展的光明前景。     

浅析影响碳素墨水显现胶带指纹的若干因素

为提高胶带粘面指纹的显现质量,便于后期针对该指纹的检验鉴定,通过对胶带粘面指纹显现过程中的各个环节进行测试、对比,可以寻找出一些影响显现效果的因素。经过实验发现,在胶带剥离阶段及对胶带的浸泡、显现阶段,各种不同的实验材质、环境、手法均会对指纹显现效果产生影响。     

EU Legislation to Reduce Carbon Emissions from Cars: Intergovernmental or Supranational Policy Making?

This article examines the making and implementation of the 2009 European Union (EU) regulation on cars and CO₂ emissions (Regulation [EC] No 443/2009). As the first legally binding measure to target the CO₂ emissions of passenger cars, this regulation represents a milestone in EU efforts to reduce the climate impacts of road transport. The analysis draws on two central theoretical perspectives on EU policy making: liberal intergovernmentalism and supranationalism. Both offer important insights, but their explanatory power varies with the policy‐making phase in focus. The analysis shows that the Commission and the car industry were instrumental in shaping what eventually became an industry‐friendly regulation applicable in all EU countries. However, far from being a case of closed negotiations between the industry and the Commission, Germany and other EU countries defending the interest of manufacturers of high‐emission vehicles made use of their powers during the decision‐making phase and succeeded in watering down the Commission's proposal.     

Diesel fumes do kill: a case of fatal carbon monoxide poisoning directly attributed to diesel fuel exhaust with a 10-year retrospective case and literature review*

While it is known that diesel fuel combustion engines produce much lower concentrations of carbon monoxide (CO) than gasoline engines, these emissions could certainly generate lethal ambient concentrations given a sufficient amount of time in an enclosed space and under suitable environmental conditions. The authors report a case of CO poisoning which was initially referred for autopsy as a presumed natural death of a truck driver found in the secure cab of a running diesel tractor trailer truck. Completion of the preliminary investigation ascribed death to complications of ischemic heart disease (IHD), pending toxicological analysis that included quantification of CO. When the toxicology results showed lethal blood COHbg, the cause of death was re-certified as CO intoxication secondary to inhalation of (diesel) vehicular exhaust fumes. Because of the unique source of fatal CO intoxication in this case, the contributory IHD and the possible contaminants in the putrefied blood, a 10-year retrospective review was conducted on all nonfire related CO deaths autopsied (n = 94) at the Office of the Chief Medical Examiner in Louisville, KY from 1994 to 2003. For validation of the COHbg detection method used by the Kentucky Office of Forensic Toxicology (KYOFT), blood samples from these cases along with controls were submitted to three laboratories using various analytical methods yielding no statistically significant differences. Lastly, an extensive literature review produced no scientifically reported cases of fatal CO poisoning attributed to diesel fuel exhaust.

Comparison of Different Analytical Methods for the Determination of Carbon Monoxide in Postmortem Blood

The determination of carbon monoxide (CO) and carboxyhemoglobin (COHb) is of utmost importance in forensic toxicology to determine the cause of death in cases of CO poisoning, fire, and explosions. To this end, reliable and updated analytical methods are required. In this paper, four different methods for the determination of carbon monoxide in postmortem blood samples were compared: (i) the spectrophotometric determination of COHb applying the method proposed by Rodkey and modified by Beutler–West, (ii) the spectrophotometric determination of CO using a micro-diffusion-based method, (iii) the determination of CO by gas chromatography coupled to a TCD detector, and (iv) the determination of COHb by blood gas analysis. Three postmortem blood samples were analyzed with all methods, and the results were comparable. The applied methodologies showed different features depending on the sensitivity, sample preparation, and volume. The HS-GC/TCD method in our hand was the most appropriate, on postmortem samples, and versatile to apply. Unfortunately, only a limited number of postmortem blood samples were available for this study due to the rarity of that kind of intoxication in our jurisdiction.
