Hair as a specimen to document tetramethylene disulfotetramine exposure

Tetramethylene disulfotetramine (tetramine) is a rodenticide that has been banned for many years in China. Since 2005, inhabitants of a village in the Henan Province have been suffering from grand mal seizures. To investigate the possibility of tetramine as the cause, we developed a method to determine tetramine in human hair. Sample preparation involved external decontamination, frozen pulverization, and ultrasonication in 2 mL ethyl acetate in the presence of cocaine-d3 as an internal standard. The method exhibited good linearity; calibration curve was linear over a range of 0.1-20 ng/mg hair. The limit of detection for the assay was 0.05 ng/mg hair. Except for one subject (No. 4), all head and pubic hair samples were positive for tetramine. The concentrations of tetramine in pubic hair were significantly higher than those in the same subjects' head hair samples. Because of a long retention in body, segmental head hair analysis cannot provide an accurate exposure history of tetramine in the body.

我国证券法的域外效力研究

证券市场的国际化使得一国证券法适用于境外发生的某些证券行为成为必要。中国致力于打造国际金融中心,建立证券市场的国际板,有必要赋予其证券法以适度的域外效力。美国证券法半个多世纪以来的实践值得研究和借鉴,特别是2010年的Morrison案判决,颠覆了此前的行为标准和结果标准,而代之以交易标准。鉴于中国目前正在修订《证券法》,建议其中增设关于域外效力的有关条款。其具体设计可保留现行的无域外效力推定,以行为地点作为判别管辖权的原则,同时辅以结果标准,允许中国法院对某些发生于境外但对境内有直接影响的证券行为进行管辖。同时,中国证券法应允许法院以非方便管辖原则为由驳回某些起诉。而从长远看,中国应积极推动制定证券跨国诉讼的多边国际公约,以根本解决管辖权冲突。     

多样化社会思潮背景下青年大学生马克思主义信仰调研分析

通过问卷调查、个案访谈方式对多样化社会思潮背景下青年大学生马克思主义信仰进行研究,结果显示：总体而言,青年大学生的马克思主义信仰现状整体上积极、健康、向上,但多样化社会思潮对青年大学生的马克思主义信仰冲击凸显,存在着知行背离、多元、注重自我感受、对马克思主义和社会主义发展前景认识模糊等倾向。因而,必须采取综合举措以提高青年大学生马克思主义信仰教育的实效性,全面实现马克思主义信仰在多样化社会思潮中的引领作用。     

我国家族企业内部纠纷的起因与规范——以家族企业内部的产权关系为视角

随着家族企业对社会经济发展作用的日益增强,我国家族企业内部纠纷已经不再是婚姻、家庭内部的事情,它关涉企业的发展与壮大甚至存活.本文认为,家庭财产与企业资产的混同,家庭生活与企业生产的重叠,个人投资与家庭投入的模糊,体力付出与脑力贡献的混淆等是家族企业内部纠纷产生的根源.因此,资产归属的事先明确是避免家族企业内部纠纷的关键.

19世纪末西方在华传教士的朝鲜观——以《教务杂志》为中心的考察

19世纪中叶以前的朝鲜，从未进入西方世俗世界的视野中。这种状况在19世纪60年代以后逐步改变。实际上，在整个19世纪后半叶，西方列强和崛起的日本都将侵略的矛头对准了朝鲜。伴随着列强侵略的进程，“隐士之国”朝鲜被揭开了神秘面纱。在向世人揭开朝鲜面纱时，西方传教士在中国创办的《教务杂志》（TheChineseRecorder）发挥了重要作用。由于西方传教士长久生活于朝鲜社会中，更少有功利性，因而反映的朝鲜面目更具有真实性和全面性。
