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.     

“多次违法行为”入罪之思考——以多次非法行医为视角

我国法律规定未取得医生执业资格的人非法行医,被卫生行政部门行政处罚两次以后,再次非法行医的,应当以非法行医罪追究其刑事责任。此种将多次行政处罚后再实施违法的行为纳入刑事犯罪构成要件或者说作为罪量要素的定罪模式是合理的,不违反禁止重复评价原则和刑法谦抑性原则。但为了防止刑事制裁范围的肆意扩大,应从违法主体、违法程序及违法次数上对"非法行医被二次行政处罚后再次非法行医"入罪进行一定的限制,以实现人权保障和惩罚犯罪的有机统一。

法律与行为选择:法律激励及其发生机制

法治理念早已深入人心,但法治是有成本的,如何降低法治成本,应该是法学研究的核心命题之一。可以预设,如果建立一种内在自觉的而非外部强制的“知法——守法”的机制,就可以大幅度降低法治成本。那么,有这种机制吗?本文从法律对人们行为选择的影响切入,论及法律的威慑机制、需求机制、公平机制和期望机制,为揭示法律与行为的内在关联提供一种新思路。     

澳大利亚外交新走向

由于战略合作的需要,澳大利亚和美国仍然保持着冷战时期建立的同盟关系.与此同时,随着其在亚太地区的战略和经济利益不断增多,澳大利亚越来越重视亚太地区,其外交重心愈益向亚太地区倾斜.现在澳外交上处于由只有对美关系一根支柱向对美关系和对亚太关系两根支柱过渡的时期.     

社会影响力债券模式下的养老服务合作治理

老龄化社会的迫近使我国养老社会服务供给面临巨大压力,倡导多元合作供给,创新理论、方法和实践已经成为解决我国老年社会服务问题的必由之路.在文献研究的基础上,创新性地利用社会影响力债券这一方兴未艾的社会治理工具,联结政府、市场和社会组织,使三方共存于同一个利益诉求整合、平等磋商协作的框架下,能够为我国社会养老服务的合作治理提供更高效的供给模式和更稳固的合作模式.以老年健康服务为例,基于社会影响力债券的运作理念,构建社会影响力债券的合作模式,关键是需要以政府、市场、社会组织与评估机构共同为主体;以实现提供高质量的养老健康服务、节省政府开支、提高资金效率为目标;以第三方评估和数字物联网技术实现过程涵盖式的结果控制.同时,坚持基于成功结果导向的付费机制,倡导互信,维护多元互益的合作机制.基于社会影响力债券的养老服务合作治理模式能为破解社会养老困局提供参考.     

Positive and Negative Emotions: Differential Associations with Sleep Duration and Quality in Adolescents

Despite positive and negative emotions being equally important predictors of adolescent wellbeing, research examining positive emotions is limited. In 4582 adolescents (69.4% females; age M?±?SD?=?14.55?±?1.74 years), we used structural equation modelling to examine associations between self-reported sleep duration and quality with positive affect, negative affect, and happiness, controlling for age and sex. Overall, sleep quality displayed stronger associations with all measures of emotions compared to sleep duration. Shorter sleep was more specifically associated with lower positive emotions (happiness, followed by positive affect), whereas poorer sleep showed stronger associations with negative affect. Protecting sleep duration may promote positive emotions and enhancing sleep quality may reduce mood disturbances. Future research could incorporate both positive and negative emotions to better understand adolescents’ wellbeing.     

全球治理背景下的工会法律参与——以工会参与核心劳工标准的实现为重点

经济全球化和全球治理的背景下,劳动标准的全球化趋势不可避免.通过对不同国家核心国际劳工标准落实情况的比较,得出了公约是否批准与国家的经济发展状况并不成正比例关系等结论.我国由于经济发展状况、政治体制等诸多方面的原因,没有完全批准8个核心劳工公约.在全球治理的背景下,中国工会应该坚持既有的批准国际劳工公约的立场,既反对将劳工标准与贸易挂钩,又要积极应对劳工标准对贸易的影响,配合政府在劳动教养制度的废除、集体合同制度的完善等诸多方面与国际劳工标准接轨.
