组织细胞DNA含量变化与死亡时间的相关性研究

目的研究人死后各器官组织细胞DNA降解变化规律,探讨其在推断死亡时间方面的应用价值,为推断死亡时间提供科学依据。方法已知死亡时间人尸体的心、肝、脾、肾,按死后6,12,24和48h四个时间段取材,制成石蜡切片,经Feulgen染色并图像分析;同时将各器官组织按不同时间段取材,制成单细胞悬液,应用流式细胞仪检测DNA含量。结果(1)人体各器官组织细胞经FCM检测,脾细胞核DNA随死亡时间延长呈现较好的下降梯度,而心、肝、肾,则由于自溶较快,死后6h细胞核DNA含量已很低,其变化情况与死亡时间的相关性不佳;(2)各器官组织细胞核DNA染色强度指数均随死亡时间的延长而下降。结论(1)机体死亡后,各器官组织细胞核DNA含量随死亡时间延长逐渐减少,具有一定的变化规律,其中以脾细胞核DNA含量的变化趋势与死亡时间最具相关性,肝、肾次之,而心最差;(2)方法学分析,图像分析技术(IAT)与流式细胞术(FCM)两种检测方法在研究组织细胞DNA含量变化方面,各有利弊,可互补不足。     

呼吁加强高等学校之间师资人才流动立法——以知识经济背景下我国高等学校公平竞争为视角

随着知识经济时代的到来，特别是随着教育体制改革的深化和市场竞争机制的确立，高等学校对高层次人才的争夺十分激烈，这使高等学校之间的竞争白热化。从规范高等学校之间公平竞争的角度出发，必须对高等学校之间的师资人才流动行为进行法制化管理。     

农村社会中传统型管理者与底层精英的社会流动

公安院校刑事科学技术专业实践教学流程设计

刑事科学技术专业是公安院校的主干专业之一，公安院校毕业生作为地方实战部门技术人员的主要来源，其素质的高低主要取决于在学校所接受教育达到的学习效果及所形成的能力水平。文章针对实践教学过程中存在的主要问题，借鉴学习——实践——再学习——再实践……的开放式的教育理念，本着理论联系实际、教学延续性、层次递进性、学生主体性及普遍可行性原则，设计了由校内实践和校外实践两大模块构成的公安院校刑事科学技术专业实践教学流程，力求更有效地提高公安教育质量，实现培养应用型与实用型人才的教学目标。     

我国农村劳动力流动的组织化问题分析

提高农村劳动力流动的组织化程度是实现我国大规模农村劳动力合理、有序流动的重要条件。政府组织、中介组织和自组织是我国农村劳动力流动的主要组织形式;农村劳动力流动组织化程度低是不争的事实,但原因是多方面的;提高农村劳动力流动组织化程度,需要健全组织系统,建立组织间的沟通、协调与衔接机制,构建网络信息共享平台。     

Information pathways into prison mental health care

Police and court liaison and diversion services provide important specialist mental health input along critical stages of the criminal justice pathway. Effective sharing of information between the services and relevant justice agencies is essential. However, various problems exist with the flow of information between agencies and services across the criminal justice pathway. This service evaluation explored how clinically relevant information is transferred, by drawing on the perspectives of prison health care staff in a large urban UK male prison. A qualitative service evaluation was conducted using semi-structured interviews with a purposive sample of 11 prison staff. The main themes included: gaps in the transfer of essential information, (particularly concerning risk and offending information); information gathering to fill these gaps; the importance of professional relationships, information sharing between agencies; and information solutions. Improving information transfer across the criminal justice pathway could prevent treatment delays and ensure more timely mental health care in prison.     

Mephitic projects: a forensic leisure science analysis of the BTK serial murders

Although it has been suggested among both forensic experts and a small number of leisure scientists that serial murder may be a form of recreational leisure, such suggestions remain largely unexplored both theoretically and empirically. Given the absence of scholarship on this possibility, this project explored and analyzed the structure and function of leisure activities within an unusual case (Dennis Rader) of serial murder. A thorough analysis of relevant case documents confirmed that serial murder itself can be experienced by the killer as a form of recreational leisure with the potential for optimal psychological experience (flow), and that various leisure activities may function in specific ways within the serial murder process. An unexpected finding in this case was that leisure, specifically project-based leisure, served to structure specific killings. Findings provide valuable new insights for forensics behavioral experts that may be used to guide future research.     

Social networks versus technical networks： How different social interaction patterns effect information system utilization in the organizations？

Improvements in information and communication technologies have reshaped production and consumption relations during the post-modern era. Societies have tried to adapt themselves to the requirements of new knowledge-based economy. It has also become vital for the organizations to meet the needs of knowledge society. Whether they are public or private, organizations play key roles in the transformation processes of the societies and economies. It is important for the organizations not only to use the latest information technologies, but also create social structures, which can ease information flow throughout the organization. Social network studies that are quite different from traditional approaches in sociology can be very useful tools to understand arid manipulate organizational networks. The results of several research activities have shown that actors use their social connections to reach information, resources and possible opportunities （Garguilo ＆ Benassi, 2000）. It is not enough to use advanced information technologies in an organization to build an effective knowledge distribution system regarding the social network perspective, it is required to understand the patterns of social interactions between actors and to find a fit between technical structure and social structure for effective knowledge-based organizational design. Structural holes theory （Butt, 1992） emphasized the importance of brokerage roles of the actors in a social network. Structural holes are unconnected actors （individuals, groups or organizations） in a social network （Burt, 1992）. If there are numerous structural holes in an organization, there will also be quite a number of brokerage opportunities for some actors in the organizational networks. Brokers are the bridges and gatekeepers who are controlling information flow in the organizations. It is vitally important to explore brokerage patterns in an organizational network for an effective knowledge based design. This study is a conceptual framework aiming at bringing an explanation to socially created information flow structures in the organizations by using structural holes theory.
