论派遣劳动者与正式工的待遇差别

那些在企业核心岗位、常年性岗位的派遣劳动者与要派单位正式工从事相同的工作,却得不到同等的待遇。这表明派遣劳动者与正式工存在待遇差别,我们应该从健全法律制度、保障集体劳权、加强政府监督三个方面入手,解决派遣劳动者待遇差别问题。     

论强制医疗程序中鉴定人出庭模式重构

出于多方考量,强制医疗程序中已对鉴定行为人精神状态作出强制性规定,并佐之以配套制度支撑.但从司法实践来看,诉讼资源与案件数量的不匹配性,加之制度设计无法有效解决出庭困境,使得鉴定人出庭率依旧不容乐观.正是因为鉴定意见的真实、准确被视为确保案件质量的核心,所以有必要在制度上进行创新探索,通过重构强制医疗程序中鉴定人选择性...

马病毒性动脉炎和马鼻肺炎抗体时间分辨荧光免疫分析检测方法的建立

以基因重组抗原包被96孔板,Eu3+标记兔抗马IgG,建立了马病毒性动脉炎和鼻肺炎抗体的时间分辨荧光免疫分析检测方法,对其特异性、灵敏性、稳定性进行了分析,并与进口ELISA试剂盒和微量血清中和试验进行了比较。结果显示,该方法交叉反应不明显,特异性好,灵敏度高于ELISA方法;该方法的批内和批间变异系数分别为2.68%～4.43%和4.21%～7.25%,Eu3+标记物可稳定保存5个月以上。证实,建立的马病毒性动脉炎和马鼻肺炎抗体的时间分辨荧光免疫分析检测技术灵敏度高,特异性和稳定性好,具有很好的应用前景。     

固相萃取技术（SPE）在苯丙胺类毒品分析中的应用

固相萃取（SPE）技术是利用固体吸附剂将目标化合物吸附,使之与样品的基体及干扰化合物分离,从而达到分离和富集的目的。SPE是20世纪70年代后期发展起来的一种样品前处理技术,本文主要综述了近10年来SPE技术在苯丙胺类毒品分析中的应用现状及其趋势。     

INTERNET INTERMEDIARIES’ LIABILITY FOR ONLINE ILLEGAL HATE SPEECH

Considering the prevalence of online hate speech and its harm and risks to the targeted people, democratic discourse and public security, it is necessary to combat online hate speech. For this purpose, internet intermediaries play a crucial role as new governors of online speech. However, there is no universal definition of hate speech. Rules concerning this vary in different countries depending on their social, ethical, legal and religious backgrounds. The answer to the question of who can be liable for online hate speech also varies in different countries depending on the social, cultural, history, legal and political backgrounds. The First Amendment, cyberliberalism and the priority of promoting the emerging internet industry lead to the U.S. model, which offers intermediaries wide exemptions from liability for third-party illegal content. Conversely, the Chinese model of cyberpaternalism prefers to control online content on ideological, political and national security grounds through indirect methods, whereas the European Union (EU) and most European countries, including Germany, choose the middle ground to achieve balance between restricting online illegal hate speech and the freedom of speech as well as internet innovation. It is worth noting that there is a heated discussion on whether intermediary liability exemptions are still suitable for the world today, and there is a tendency in the EU to expand intermediary liability by imposing obligation on online platforms to tackle illegal hate speech. However, these reforms are again criticized as they could lead to erosion of the EU legal framework as well as privatization of law enforcement through algorithmic tools. Those critical issues relate to the central questions of whether intermediaries should be liable for user-generated illegal hate speech at all and, if so, how should they fulfill these liabilities? Based on the analysis of the different basic standpoints of cyberliberalists and cyberpaternalists on the internet regulation as well as the arguments of proponents and opponents of the intermediary liability exemptions, especially the debates over factual impracticality and legal restraints, impact on internet innovation and the chilling effect on freedom of speech in the case that intermediaries bear liabilities for illegal third-party content, the paper argues that the arguments for intermediary liability exemptions are not any more tenable or plausible in the web 3.0 era. The outdated intermediary immunity doctrine needs to be reformed and amended. Furthermore, intermediaries are becoming the new governors of online speech and platforms now have the power to curtail online hate speech. Thus, the attention should turn to the appropriate design of legal responsibilities of intermediaries. The possible suggestions could be the following three points: Imposing liability on intermediaries for illegal hate speech requires national law and international human rights norms as the outer boundary; openness, transparency and accountability as internal constraints; balance of multi-interests and involvement of multi-stakeholders in internet governance regime.

土地承包经营权制度改革的思考——一种法和经济学分析的思路

本立足于法和经济学的分析方法，揭示了我国农村土地承包经营权制度效率低下的根本缘由，提出了增进这一制度效率的立法途径，认为：从经济分析角度睦，重构农村土地集体所有权制度仍是立法成本最低的一种立法路径，从交易成本理论考察，应将村民小组界定为集体土地所有权主体，土地承包权的物权化有助于消除承包合同双方的协议障碍，降低交易成本，物权法在对土地使用权进行以利配置时，应区别土地承何种功能而遵循不同的价值取向。
