新《保险法》对中国海上保险合同法律的影响

2009年2月公布的《中华人民共和国保险法》在很多方面进行了重大的修改,势必对中国海上保险合同法律制度产生重要影响。一方面是对海上保险合同法律的补充,另一方面同《中华人民共和国海商法》在海上保险合同不少制度和规则上出现了程度不同的差异。而这些也为后者未来的修改提供了丰富的素材和良好的借鉴蓝本。

I don't Agree with Nick: Retrodicting the Conservative–Liberal Democrat Coalition

Insider and journalistic accounts of the formation in May 2010 of the Conservative‐Liberal Democrat coalition actually, although not explicitly, rely on types of explanation familiar to those who study politics. They tell us that structure (or at least the economy) was important. So too, they suggest, were institutions (timing and the rules of the game). They also stress the importance of contingency (‘events, dear boy, events’) and agency (who did and said what to whom). While none of these things were unimportant, they only served to make certain an outcome that anyone with a passing acquaintance with the theory and the practice of coalition formation would have predicted—namely a ‘minimum winning coalition’. The only thing that could have made that outcome uncertain was a fundamental ideological difference between the two parties involved; however, it quickly became apparent—to the surprise of those of us who failed to appreciate how much the Liberal Democrats had changed—that no such difference existed. Indeed, it is possible to argue that the coalition formed was not merely minimum winning but ‘minimum connected winning’. As such, its formation was not so much breathtakingly bold and exciting as pretty much inevitable. In the end, the maths and the physics mattered more than the chemistry. Fortunately for the Conservatives, the Liberal Democrats seriously underplayed their hand in the negotiations, with possibly disastrous consequences for them in the long term.     

P300测谎的新取向

现在,P300是研究者使用的最多也是研究的最深入的一种脑电指标。根据实验模式的不同,目前的P300研究可以分为两大类：模拟犯罪模式和自传性信息模式。而目前P300研究的取向则集中在三个方面：一个是关于反测谎对P300的影响;一个则探讨撒谎动机或意向对P300的影响;还有一些研究则集中在将P300与其他脑电指标结合测谎上。如今,P300测谎的实验室研究已经颇有成效,但仍有生态效度不足的缺点。今后P300测谎研究应该以实际生活中的真实犯罪案件或普通人的过失行为为主,提高实验的生态效度及应用性。     

Änderungskündigung

Für Bestandverh?ltnisse, auf die noch § 1 Abs 2 Z 4 MRG aF weiterhin anzuwenden ist (§ 49d Abs 2 MRG), gilt auch § 45 Abs 3 MRG nF wie für Mietgegenst?nde nach § 1 Abs 4 Z 1 MRG nF (weiter). Ab dem Anhebungsbegehren des Vermieters nach § 45 MRG gelten ua die §§ 18ff MRG. Nur wenn das Verlangen nach einem Erhaltungsbeitrag wegen der H?he des vereinbarten Hauptmietzinses nicht m?glich w?re, der vereinbarte Hauptmietzins aber zur Erhaltung des Hauses nicht ausreichte, k?me eine "?nderungskündigung" in Betracht. Es ist n?mlich lediglich die Einhebung eines Erhaltungsbeitrages, nicht aber eine ?nderungskündigung mit dem Ziel m?glich, den Mieter zu einer Erh?hung des Hauptmietzinses auf das angemessene Ma? zu bringen.     

Methyl 3-[3',4'-(methylenedioxy)phenyl]-2-methyl glycidate: an ecstasy precursor seized in Sydney, Australia

Five 44 gallon drums labeled as glycidyl methacrylate were seized by the Australian Customs Service and the Australian Federal Police at Port Botany, Sydney, Australia, in December 2004. Each drum contained a white, semisolid substance that was initially suspected to be 3,4-methylenedioxymethylamphetamine (MDMA). Gas chromatography-mass spectroscopy (GC/MS) analysis demonstrated that the material was neither glycidyl methacrylate nor MDMA. Because intelligence sources employed by federal agents indicated that this material was in some way connected to MDMA production, suspicion fell on the various MDMA precursor chemicals. Using a number of techniques including proton nuclear magnetic resonance spectroscopy ((1)H NMR), carbon nuclear magnetic resonance spectroscopy ((13)C NMR), GC/MS, infrared spectroscopy, and total synthesis, the unknown substance was eventually identified as methyl 3-[3',4'(methylenedioxy)phenyl]-2-methyl glycidate. The substance was also subjected to a published hydrolysis and decarboxylation procedure and gave a high yield of the MDMA precursor chemical, 3,4-methylenedioxyphenyl-2-propanone, thereby establishing this material as a "precursor to a precursor."     

Postmortem Blood Concentrations of R‐ and S‐Enantiomers of Methadone and EDDP in Drug Users: Influence of Co‐Medication and P‐glycoprotein Genotype

Abstract: We investigated toxicological and pharmacogenetic factors that could influence methadone toxicity using postmortem samples. R‐ and S‐methadone were measured in femoral blood from 90 postmortem cases, mainly drug users. The R‐enantiomer concentrations significantly exceeded that of the S‐enantiomers (Wilcoxon’s test, p < 0.001). The samples were divided into four groups according to other drugs detected (methadone only, methadone and strong analgesics, methadone and benzodiazepines, or methadone and other drugs). There was no significant difference in any of the R‐methadone/total methadone ratios among the four groups. The median R/S ratio was 1.38, which tends to be higher than that reported for the plasma of living subjects. In addition, we investigated whether small nucleotide polymorphisms in the MDR1 gene that encode the drug transporter P‐glycoprotein were associated with the concentrations of R‐ and S‐methadone and its metabolite 2‐ethylidene‐1,5‐dimethyl‐3,3‐diphenylpyrrolidine. No significant association was detected.     

P物质在过敏性休克家兔胃肠道内的表达

目的观察P物质在过敏性休克家兔胃肠道组织中随时间变化的规律,探讨其在过敏性休克中的作用。方法 30只家兔随机分为实验组(24只)和对照组(6只)。实验组采用多人混合血清致敏家兔,建立过敏性休克模型。休克不同时间段(猝死即刻、休克0.5h、休克1h、休克2h)提取家兔胃、小肠、圆小囊。冰冻切片,应用免疫组化(IHC)SP法和原位杂交(ISH)方法进行P物质染色,BI-2000计算机图像分析系统进行图像分析,计算阳性积分光密度值(IOD),用SPSS11.5统计软件进行方差分析,SNK检验。结果与对照组相比,实验组各小组胃、肠、圆小囊P物质蛋白和mRNA表达明显增加,且随着休克时间的变化逐渐减弱(P0.001)。IHC方差分析结果为:胃组织F=198.008,肠组织F=56.796,圆小囊组织F=67.231;ISH统计学分析方差分析结果为:胃组织F=67.506,肠组织F=72.117,圆小囊组织F=216.798。结论家兔胃肠道P物质在过敏性休克后一段时间内(2h)均表达增高,随休克时间的延长逐渐下降。     

试论“后悔权”设立之法学证成

作为舶来事物,＂后悔权＂一经浮出水面,即遭受或赞或弹的命运。其中的质疑不无道理,但又有失偏颇。据此,厘清＂后悔权＂之真正意旨,区别相关权利,奠定对其讨论的正确基础实为必须且为必要。此外,＂后悔权＂作为一个货真价实的＂国际惯例＂,无理由将之拒之门外,但为避免＂水土不服＂的尴尬,其设立必须兼顾本土实际,即：一切从实际出发,设立中国特色的＂后悔权＂制度——＂有限后悔权＂制度。
