交通警察正当执法权益受侵害的原因及其维护

交通警察作为公安机关的业务警种和国家执法机构,是离人民群众最近、最直接的执法群体,其执法活动应依法受到保护,执法行为神圣不可侵犯。然而在工作实践中,交通警察正当执法权益受到不法侵害的事件却屡屡发生,这些事件严重影响了交通警察的工作积极性和公安机关的威信。各级公安机关应采取切实可行的措施维护广大交通民警的正当执法权益。

Negotiating a New Social Contract for Work: An Online,Distributed Approach

A massive open online course (MOOC) entitled “Shaping the Future of Work” (offered through MITx, the Massachusetts Institute of Technology's online learning division) has been the context for a multiparty simulation designed to produce classroom negotiation results that will have social impacts. After running the course in the MOOC context three times and in face‐to‐face settings eight times, we noticed that key themes emerged. Participants have brought their own workforce perspectives to their simulation roles as employers, worker representatives, elected officials, and educators. They have called for reciprocal agreements centered on fair treatment and representation in the workplace, improved organizational performance, investments in skills and capabilities, aligned rewards and benefits for workers, and work–life balance in communities. We continue to use the simulation in the classroom and are exploring ways to expand its use. In the meantime, in this article, we discuss how the insights gleaned from this simulation could be used to crystallize and advance a new social contract at a time when the public policies, institutions, and organizational practices governing employment relations have not kept up with the dramatic changes taking place in the workforce, nature of work, and overall economy.     

How Measurement Error in Content Analysis and Self-Reported Media Use Leads to Minimal Media Effect Findings in Linkage Analyses: A Simulation Study

In the debate on minimal media effects and their causes, methodological concerns about measurement are rarely discussed. We argue that even in state-of-the-art media-effects studies that combine measures of media messages and media use (i.e., linkage analyses), measurement error in both the media content analysis and the media use self-reports will typically lead to severely downward-biased effect estimates. We demonstrate this phenomenon using a large Monte Carlo simulation with varying parameters of the content analysis and the survey study. Results show that measurement error in the content analysis and media use variables does indeed lead to smaller effect estimates, especially when the media messages of interest are relatively rare. We discuss these findings as well as possible remedies and implications for future research.     

交通事故脑外伤所致精神障碍伤残评定有关问题

在交通事故受伤人员脑外伤所致精神障碍伤残评定中,由于《道路交通事故受伤人员伤残评定》中涉及精神伤残评定条款内容可操作性差,精神伤残评定客观检查及量化指标较少,导致评定意见不一致,给交通事故理赔带来困难。在此就精神伤残评定技术操作中的有关问题提出一些经验性观点。     

3D Finite Element Model of Human Knee Injuries in the Traffic Accident

Objective To explore the injury mechanism of the human knee in a traffic accident by estab lishing a 3D finite element （FE） model. Methods The FE model, composed of femur, tibia, fibula, patel la, meniscus, knee ligaments and surrounding soft tissues, was reconstructed by CT scanning data from a male volunteer. Validation was performed by the lateral impact simulation, and the stress and strain re sults were obtained to be compared with those previously reported for injury prediction. Results The re suits derived from the FE model were found to be similar with those previously reported, most of the ligaments and meniscus wounded at 40 m/s collision, which was readily observed. Conclusion The simu lation results generated by FE model can be effectively used for the injury mechanism analysis of initial contact.

试论因逃逸致人死亡

"因逃逸致人死亡"之合理诠释乃交通肇事逃逸案件正确认定之基础.然而,实践之复杂及理论之分歧却一直困扰着条文之司法适用."因逃逸致人死亡"之逃逸、致人死亡、主现心理态度等构造体系,情节加重犯之加重情节之法律性质及具体适用等诸多方面,学界与实务界认识并不统一.因此,有必要对其进行充分的阐释与准确厘定,以便司法之正确认定与合...
