Race and Ethnicity: Responsible Use from Epidemiological and Public Health Perspectives

While the concepts of race and ethnicity have been abused historically, they are potentially invaluable in epidemiology and public health. Epidemiology relies upon variables that help differentiate populations by health status, thereby refining public health and health care policy, and offering insights for medical science. Race and ethnicity are powerful tools for doing this. The prerequisite for their responsible use is a society committed to reducing inequalities and inequities in health status. When this condition is met, it is irresponsible not to utilize these concepts.     

侦查讯问制度与对抗制庭审制度之价值协同问题研究

侦查讯问具有结果价值和程序价值。这两种价值的不同追求决定着侦查讯问的诉讼结构,而且该结构一般与庭审方式保持了相同的理念运作。然而从我国1996年刑诉改革以来,对抗制特色庭审方式与强职权侦查讯问方式存在着不可调和的价值冲突,以至司法实践中两种制度难以对接运作,问题颇多。     

当前我省农村思想政治工作中存在的问题及对策

当前我省思想政治工作还存在诸多不足和不少急待解决的问题,主要是思想政治工作缺乏针对性和实效性。造成这些问题的原因主要是一些领导认识不够,思想政治工作队伍素质低。加强我省思想政治工作必须以“三个代表”重要思想为指导解决认识问题,切实加强制度建设,提高队伍素质。     

关于提高国有企业人力资源利用率的研究

拥有人才优势,才能拥有竞争优势,这是一个不争的事实。作为人才流失最严重的企业类型之一——国有企业人才流失给企业带来的损失是巨大的,并导致商业泄密现象和劳动争议增多,影响到了企业生产经营上的连续性和稳定性,制约了国有企业的发展和人才整体素质的提高。对国有企业人才流失的成因进行分析,探讨国企吸纳和稳定人才的方法,寻找提高国有企业人力资源利用率的对策,正在成为相关主管部门和广大国有企业关注的焦点问题。     

The Effect of Negotiation Practices on the Relationship between Suppliers and Customers

This article examines the effects of negotiation practices, such as coercion and contract formality, on how suppliers and customers perceived the resulting business relationship. We conducted a purchasing negotiation simulation with students in a classroom setting in which participants competed for resources in a mock supply-chain context. The participants were surveyed at key stages of the ongoing negotiation in order to measure their behaviors as a customer–supplier relationship developed. The data were used to test several hypotheses developed from the marketing and purchasing literature. The hypotheses were analyzed using structural equation modeling.
Results demonstrated that the use of coercive techniques by negotiators during negotiation had a negative effect on satisfaction. In addition, the findings showed that, as expected, negotiators entering a negotiation with a cooperative orientation would tend to avoid the use of coercive practices during negotiation. The cooperative orientation also exhibited an unexpected positive effect on the formalization of the design of the contract between the parties. This study contributes to the current knowledge base focusing on the creation of agreements between companies and will, we hope, encourage the integration of suppliers and customers in an operating context within a supply-chain setting.     

Demand Pull Technology Transfer Applied to the Field of Assistive Technology

Technology transfer has generally had little impact on the assistive technology industries serving small, highly fragmented “disability markets.” Persons with disabilities often require specialized, relatively sophisticated technology. Third-party payer reimbursement rates and the low levels of disposable income among disability populations often cap product pricing. Transferring technology to these industry segments therefore poses special challenges. In October 1998, the Rehabilitation Engineering Research Center on Technology Transfer initiated the “Demand-Pull Project on Wheeled Mobility.” Successful transfers resulting from this project demonstrate that a systematic technology transfer process can be successfully applied to industries serving specialized and underserved niche markets.
