机动车登记中的物权保护问题探析

对于机动车的权属问题,有必要立足于物权的基本原理,从私法和公法的双重角度进行理论分析和立法调整。本文认为,机动车登记行为具有行政确认和行政许可的双重法律属性,公安机关在办理机动车登记中对相关事实的审查属于实质审查。《物权法》对机动车登记效力采取的是登记对抗主义而非登记要件主义。对于登记中的错误应区分具体情形,采取不同的方式予以补救。对于第三人善意购买的被盗抢机动车,应当采取有偿回复的方式予以处理,不宜不加区分地予以追缴。     

卧底侦查证据问题研究

卧底侦查作为一种特殊的侦查手段,对于某些重、特大犯罪案件的侦破有着无法替代的作用。但是,由于其特殊性极易造成严重的后果,必须对其进行严格的限制。本文通过对实践侦查工作的调查与分析,结合我国侦查实际,提出在我国应该明确卧底侦查的法律地位,赋予侦查机关卧底侦查权,对如何具体规定卧底侦查提出了构想。     

不同固定液对冷冻组织病理切片HE染色质量比较

目的探讨选择不同固定液处理冷冻病理组织HE切片质量的效果。方法选择我中心冷冻后尸体法医病理解剖100例,冷冻温度为-22±3℃,针对心、肝、脑以及肺选择6种不同固定液处理组织块并制作HE切片,对切片质量进行对比分析。结果不同固定液针对不同冷冻脏器处理效果有显著差异,各组HE切片观察结果显示:甲醇固定液处理脑组织处理更优,EAF固定液处理心肌组织更优,10%中性甲醛处理肝脏组织更优,丙酮固定液处理肺组织更优。结论不同脏器因其组织结构及细胞所含成分不同,选择相应固定液能有效改善或缓解因冷冻后对组织及细胞带来的不良效应。     

True and false memories in middle childhood: the relationship with cognitive functioning

This study was designed to investigate developmental changes in true and false memories and to detect links among them in middle childhood. Participants were 372 Italian children (from 6 to 11 years, 174 males) divided into two age groups. After hearing a story, children provided a free-recall and their true and false retrieved information was measured. Then children were repeatedly asked some true and misleading questions about the story and their cued-recall and interrogative suggestibility were measured. Finally, children again recalled the story to assess the post-event misinformation effect of the suggested information. Individual differences in fluid intelligence, working memory and executive functions were also assessed to investigate their relationships with true and false memories. Typical age effects were found in memory recall and interrogative suggestibility. Interesting links among true, spontaneous and suggested false memories were found. Finally, analyses did not reveal the existence of a relationship between suggestibility and cognitive functioning.     

Public Service and Commercial Broadcasting: Impacts on Politics and Society

This article provides an accessible overview of the growing research literature on the impact of public service and commercial broadcasting and highlights its main implications for policy discussions about the future of public service broadcasting in Western societies. It shows that the populations of countries with public service broad‐ and narrowcasting are better informed about government and politics, are more trusting of other people, have more positive civic attitudes, have greater confidence in democratic institutions and are more likely to engage in democratic politics. Moreover, levels of social trust are higher in countries which have a significant public service element in their media systems, even among individuals who do not habitually watch public TV channels. The article ends with a brief discussion of the implications of this research for the future of public broadcasting in the Western world.     

Public sector leadership‐subordinate ethical diffusion conundrum: perspectives from developing African countries

The interaction between organizational superiors and their subordinates has a practical implication on the entire organizational life cycle in terms of ethical conduct. This study explores how ethics among public leadership could trickle down on the conduct of public employees by using two empirical cases from developing African countries context. Using the attraction–selection–attrition and social learning models, the study assesses how superiors influence street level bureaucrats' interaction with clients or customers. Drawing from existing cases and other secondary data, we propose a leadership‐ethical diffusion model that argues that subordinates' perception and experience of superiors' behavior tend to create a kind of organizational ‘ethical groupthink’, which spans the rank and file of the organization.

我国多层次社会保障体系内部影响:促进还是抑制?

习近平在党的十九大报告中做出了全面建成多层次社会保障体系的战略部署,各层次之间的影响机制值得研究。基于政策反馈理论发现,一个层次可以通过两个平行的中介机制影响另一个层次,具体表现为:解释效应,行动者对层次Ⅰ的认知影响他对层次Ⅱ的认知,继而影响行动意愿;资源效应,行动者在层次Ⅰ的资源变化影响他在层次Ⅱ的预算,继而影响行动能力。以2008-2015年A股上市公司为样本,检验社会保险影响补充保险的双重中介机制。结果显示:基本养老保险通过解释效应促进企业年金参保和缴费,通过资源效应抑制企业年金参保;基本医疗保险通过解释效应促进补充医疗保险参保和缴费,没有显著的资源效应;社会保险对补充保险既有推动作用也有抑制作用。建议科学评估社会保障体系各层次之间的解释效应和资源效应,规避相互挤出,从解释效应和资源效应两面着手推动多层次社会保障体系的完善。     

A Study on the Estimation of Postmortem Interval Based on Environmental Temperature and Concentrations of Substance in Vitreous Humor

A method to determine postmortem interval (PMI) based on environmental temperature and the concentrations of vitreous humor (VH) molecules were explored. Rabbit carcasses were placed in a chamber at 5, 15, 25, or 35°C, and 80–100 μL of VH was collected with the double‐eye alternating micro‐sampling method every 12 h. A Roche DPPI biochemical analyzer was used to measure the concentrations of six substances in VH samples. The interpolation function model and mixed‐effect model were employed for data fitting to establish equations for PMI estimation. The concentrations of K⁺, P, Mg²⁺, creatinine (CRE), and urea nitrogen (UN) exhibited an upward trend with increasing PMI in all temperature groups, while the concentration of Ca²⁺ showed a downward trend. Validation results using K⁺ and Mg²⁺ ions revealed that the mixed‐effect model provided a better estimation than the interpolation function model using the data from our experiment. However, both models were able to estimate PMI using temperature and VH molecule concentrations.
