An in vitro study of the accuracy and precision of Breathalyzer models 900, 900A, and 1000

Ninety Breathalyzer instruments (Model 1000) and twenty instruments (Models 900, 900A) were studied using a protocol described by the Department of Transportation's "Standard for Devices to Measure Breath Alcohol." Although the mean of each of three concentrations tested (0.05, 0.10, and 0.15 g/210 L) compared favorably in both series, the standard deviation was consistently higher for the Model 1000 instruments. The Model 1000 instruments also produced a significant number of test results which exceeded the normally expected scientific deviation.     

Heroin abuse and a gas chromatographic method for determining illicit heroin samples in Singapore.

The abuse of heroin (diacetylmorphine) in Singapore escalated sharply in 1975 and 1976, as indicated by the 35-fold increase in the number of heroin seizures and the 20-fold increase in the urine samples containing morphine since 1974. A rapid and simple GC method has been described to estimate diacetylmorphine (and caffeine). Monoacetylmorphine and acetylcodeine may be ascertained by an additional step involving acetylation. All gas chromatograms of a large number of samples analyzed consistently had the same pattern, indicating that they possibly had a common origin. This GC "fingerprint," together with the quantitative data, appears to be characteristic of the illicit Asian or Chinese type of heroin found in Singapore. The proportions of the four major ingredients in some twelve typical samples have been tabulated. Statistical data confirming the accuracy and reproducibility of the analytical method have also been presented.     

论违规审核证券发行的侵权责任

现行《公司法》、《证券法》立法仅规定了违规审核人员的行政责任和刑事责任 ,而未涉及侵权责任问题 ,存在立法缺漏。违规审批、核准证券发行的行为完全符合侵权责任的构成要件。一般而言 ,违规审批、批准证券发行的侵权责任应由该证券发行审核机构承担 ,但审核人员犯滥用管理公司、证券职权罪的 ,应自己承担相应的侵权责任。违规审核证券发行的侵权责任的范围应从投资人的实际直接损失为限。投资人可选择单独诉讼或者共同诉讼方式 ,通过行政侵权诉讼或附带民事诉讼的途径 ,追究违规审核证券发行的侵权责任     

关于劳动争议几个法律问题的思考

劳动争议是当前比较突出的社会矛盾,笔者试图以归纳性的逻辑方法论证现行的有关劳动争议方面的法律、法规以及劳动行政部门的解释、批复存在的实践性问题。在此基础上,根据公正与效率的法律精神,就劳动争议方面如何建立健全科学的法律体系、改革诉讼活动、切实保护劳动者和弱势群体的民事权利及其诉讼权利等问题提出个人设想,盼望引起司法界的议论和立法者的重视。     

当代西方政治思潮的基础与特征

当代西方政治思潮是西方社会政治现象的反映,是解构当代西方政治的基础。时代的变化、国情的差异,使得制约西方政治思潮的基础与条件日趋复杂。政治思潮的发展呈现出多元化的态势,并形成了关注现实、主题泛化和流派纷呈的基本特征。     

外部性与政府干预行为

市场机制无法解决而又普遍存在的外部性问题，通过政府干预可以获得消除和矫正。但是政府干预行为本身也会产生外部性问题。对政府干预行为所派生的外部性问题可以通过严格界定政府干预的界限、引入市场机制、加强政府法治化建设、提高公共政策质量来防范和矫正。
