腔内泌尿外科若干技术的评价

随着高科技的发展,通过各种多功能的内镜技术,已可将电、激光、超声及机械力转入到整个泌尿系统的腔道内,不仅可以诊断疾病,还可以治疗疾病。回顾腔内泌尿外科的发展历史,社会实践的需要是腔内泌尿外科发展的根本动力,科学技术进步推动医学的发展,高新技术促进了腔内泌尿外科的迅速发展。     

对建立我国艾滋病防治督导与评估体系的思考

随着我国艾滋病防治工作的持续深入,定期对艾滋病防治工作进行督导与评估越来越重要。但是,到目前为止,我国尚未建立国家综合协调的艾滋病防治督导与评估体系。通过对建立国家艾滋病防治督导评估体系的必要性、可行性及存在的问题进行分析,围绕如何构建一个统一、综合、有效的督导评估体系提出政策建议。     

医学专科能力评审的争议及规避策略

医院的医学重点专科建设是医院发展的重要战略,如何认定某医院某专科为地方的重点专科,是一个系统工程。地方卫生行政主管部门如何把握评审认定标准,展示政府执政的公正公平,是十分敏感的问题,它蕴藏着很大的风险。在重点专科的评定过程中如何体现政府形象,规避行政风险,需要认真探讨。结合某市重点专科检查的实际情况进行分析,就此种争议及规避策略提出建议。     

管理培训背景下适应性绩效的结构分析

本研究以适应性绩效理论为基础,在上海、北京、广州、浙江、江苏、重庆等地用问卷调查了十多个企业的管理培训实施情况,得到了334个有效样本。对数据进行探索性因素分析和验证性因素分析后,得到了管理培训背景下的四因素适应性绩效结构模型,四个因素分别被命名为:压力和应急处理、创新解决问题、岗位持续学习以及人际和文化适应。该适应性绩效结构为管理培训评估研究中效标的确定提供了新思路。最后讨论了今后研究需要进一步注意的问题。     

Right Motive, Wrong Action: Direct Consequentialism and Evaluative Conflict

In this paper I look at attempts to develop forms of consequentialism which do not have a feature considered problematic in Direct Consequentialist theories (that is, those consequentialist theories that apply the criterion of rightness directly in the evaluation of any set of options). The problematic feature in question (which I refer to as ‘evaluative conflict’) is the possibility that, for example, a right motive might lead an agent to perform a wrong act. Theories aiming to avoid this phenomenon must argue that causal relationship entails motives and acts (for example) having the same moral status. I argue that attempts to ensure such ‘evaluative consistency’ are themselves deeply problematic, and that we must therefore accept evaluative conflict.     

The linear utility model for optimal selection

A linear utility model is introduced for optimal selection when several subpopulations of applicants are to be distinguished. Using this model, procedures are described for obtaining optimal cutting scores in subpopulations in quota-free as well as quota-restricted selection situations. The cutting scores are optimal in the sense that they maximize the overall expected utility of the selection process. The procedures are demonstrated with empirical data.     

肿瘤内科治疗的疗效评价

肿瘤内科治疗是肿瘤综合治疗三大手段之一,在肿瘤治疗中占有举足轻重的地位。肿瘤内科治疗的疗效评价也逐步发展和完善。新的疗效评价指标逐渐被接受,延长生存期和提高肿瘤病人的生存质量已成为肿瘤内科治疗疗效评价的原则,临床肿瘤学工作者应转变观念,以利于更好地开展临床工作。     

Who knows what's good to eat? Infants fail to match the food preferences of antisocial others

Humans gather most of their knowledge about the world, including objectively true facts and specific cultural norms, by observing and being taught by others. Some individuals are worthy teachers and objects of imitation, having knowledge of cultural practices and positive intentions to inform. Others are better ignored because they are ignorant, because they mean us harm, or simply because we do not wish to be “like them.” This study examines whether 16-month-olds are sensitive to the pro- or antisocial behavior of a source that demonstrates preference for two novel foods. Infants took the emotional reactions displayed by novel and previously prosocial sources, but not antisocial sources, into account when deciding what to eat. These results suggest that others’ social behavior influences infants’ likelihood to match their preferences, illustrating the influence of social evaluation on social learning.     

Decomposition of multivariate utility functions in non-additive expected utility theory

In expected utility many results have been derived that give necessary and/or sufficient conditions for a multivariate utility function to be decomposable into lower-dimensional functions. In particular, multilinear, multiplicative and additive decompositions have been widely discussed. These utility functions can be more easily assessed in practical situations. In this paper we present a theory of decomposition in the context of nonadditive expected utility such as anticipated utility or Choquet expected utility. We show that many of the results used in conventional expected utility carry over to these more general frameworks. If preferences over lotteries depend only on the marginal probability distributions, then in expected utility the utility function is additively decomposable. We show that in anticipated utility the marginality condition implies not only that the utility function is additively decomposable but also that the distortion function is the identity function. We further demonstrate that a decision maker who is bivariate risk neutral has a utility function that is additively decomposable and a distortion function q for which q(½) = ½.
