An experimental model of regulating the sharing economy in China: The case of online car hailing

Online car hailing represents a disruptive innovation model in the sharing economy and requires a new regulatory response. China's attempts to regulate this emerging industry can be considered highly experimental model. To relieve the pressure from offline competitors and to clarify the ambiguous legal status of online car hailing, China currently enforces a strict regulatory scheme through what can be described as a central-local dual system. Questions, however, have arisen regarding the legality, proportionality and effectiveness of this approach. Moreover, the current system's choice for a segmented market strategy heavily impairs the sustainable development of the sharing economy. Therefore, the adoption of Internet-based regulations for online car hailing might create better prospects to establish a fairly competitive market as well as to further boost the ever dynamic Internet sharing economy in China.     

Societal openness during the urban crisis. Partner selection in the 19th-century Belgian textile cities Ghent and Verviers

This paper examines the partner selection of the lower classes during an urban crisis period in early industrial Belgian cities. It was found that in this period characterized by an economic transition, overpopulation, migration and a low standard of living, social heterogamy was high, whereas social homogamy increased, or was ‘restored’, in the subsequent period. The urban crisis effect on partner selection contradicts the claims of modernization theory that there was a gradual increase in societal openness and that societal openness was typically modern, but it fits the idea of the informalization of marriage, a process marked by an increase in unmarried cohabitation and illegitimacy.     

中国（上海）自由贸易试验区公安警务工作实践研究

2013年7月3日,国务院正式批准建设中国（上海）自由贸易试验区。上海自贸区的各项创新举措是对现行行政管理模式与管理体制的一次挑战,也将给负责公共安全与社会治安服务管理的警方带来全新的考验。公安机关应当深入分析上海自贸区的建立可能对警务工作产生的影响,并制定相应的工作对策。     

公安高校实验教学示范中心教学资源共享的探索

公安高校实验教学资源的有限性,决定了公安高校实验教学资源应当使用共享。当前这方面存在一些急须解决的问题。警务技能综合实训教学中心项目建设实践,为实施资源共享,从实验教学资源共享的规章制度和实验室管理共享平台的建设等方面入手,以实验硬件、软件资源共享为核心,资源整合为手段,对实验教学的资源进行战略重组和资源优化,以完善公安高校实验教学资源共享机制。     

The modern trends in alcohol, drugs and driving research

Research on alcohol, drugs and driving can be broadly separated into experimental and epidemiological studies. Every approach has its inherent advantages and disadvantages. Experimental studies can result in an interpretation by single cause, but can only identify potential risks, and the results can sometimes be of limited value because of the use of non-realistic doses or because of the drug use history or inter-individual differences of the volunteers. Recent studies have used higher, more realistic doses and paid more attention to the combination of alcohol and drugs and have shown that the chronic use of illicit drugs can be associated with some cognitive and/or psychomotor impairment, and can lead to a decrease in driving performance even when the subject is no longer intoxicated.Epidemiological studies include roadside surveys, studies in a subset of drivers, accident risk studies, responsibility analyses, surveys and pharmaco-epidemiological studies. Between studies, results may be incomparable due to testing different populations, different kinds of samples, etc. More large-scale roadside studies are conducted now.Advances in analytical toxicology have also contributed to a better understanding of the risks associated with driving under the influence. While older studies measured the inactive metabolite THC-COOH and did not show an increased risk in cannabis-positive drivers, more recent studies measured the active THC in blood and did show a concentration dependent increase in crash risk. The use of LC–MS/MS has allowed more broad-range screening as this technique can measure many different drugs in a small sample volume. While some older studies used saliva but had many analytical problems (including an insufficient sample volume in up to a third of the cases), newer methods of saliva sampling and analysis give better results. The use of saliva for roadside surveys allows non-invasive sampling, but the lack of correlation with the concentrations in blood makes interpretation of results difficult.The results of both epidemiological and experimental studies should be combined to obtain a good estimate of the impact of certain drugs on driving performance and accident risk. In 2006–07 a committee of international experts drafted guidelines for future research into drugs and driving. These have been taken on board by the DRUID project, a large-scale EU funded project on driving under the influence of drugs, alcohol and medicines.     

An experimental evaluation of teen courts

Teen Court (TC) is a juvenile diversion program designed to prevent the formal processing of first-time juvenile offenders within the juvenile justice system. TC instead utilizes informal processing and sanctions in order to prevent future offending. Despite its widespread popularity throughout the United States of America, little rigorous research has been conducted on the effectiveness of the TC model for reducing recidivism. Using an experimental design, this study examined the effectiveness of TC in reducing recidivism and improving the attitudes and opinions of juvenile offenders in comparison with a control group of youth who were formally processed. Self-reported delinquency was higher for those youth who participated in TC. TC youth were also found to have significantly lower scores on a scale of belief in conventional rules than had youth who were processed in the Department of Juveniles Services. Implications of these findings are discussed.

论《刑事侦查》课堂教学实践观

实践的核心就是发挥个体的主观能动性 ,主动去认识世界和改造世界。这是对课堂教学观进行实践构造的基础。树立以学生为中心的教育主体观 ,并以此为基础来确定实践性教学原则。课堂教学要从传统的只重视认知性学习转变到以培养学生的创新精神和实践能力为重点的目标上来 ,教学内容的变革要从重视学科体系为主的书本知识转到对学生的全面影响上来 ,教学模式要从传统的单一讲授向多元化转变 ,教学手段要从传统的权威控制转变到以教学目标为导向上来     

男炎消对大鼠实验性前列腺炎影响的病理学观察

目的 :观察男炎消对大鼠实验性前列腺炎的组织病理学影响。方法 :采用向大鼠前列腺组织内注入角叉菜胶的方法复制大鼠前列腺炎模型 ,并分别对模型组及口服男炎消冲剂后的大鼠组进行前列腺组织病理学检查。结果 :口服男炎消冲剂后的大鼠前列腺湿质量均比模型组明显要轻 ,两者比较有统计学差异 (P <0 .0 5) ,且镜下炎症改变亦比模型组明显轻。结论 :口服男炎消冲剂对角叉菜胶所致大鼠实验性前列腺炎具有较好的抑制炎症发生作用。

论公安机关的公共性以及与阶级性的关系

公安机关的“公共性”是指公安机关的各项工作必须面向社会公众,公安工作的唯一目的是为了实现社会和公共安全利益,公安机提供的是涉及社会全体成员共享的公共安全产品和服务。加强公安机关公共性的研究有助于公安机关克服“自利性”,发挥公益性;克服公安机关片面追求政治镇压职能、忽视社会管理职能的片面倾向;有助于树立“执法为民”的思想观念和有助于确立警察权使用的公共性原则。公安机关的公共性与阶级性是相辅相成、辩证统一的关系。
