Person Perception through Gait Information and Target Choice for Sexual Advances: Comparison of likely Targets in Experiments and Real Life

Point-light and full-view short video clips of female walkers were displayed on a CRT monitor and male students rated the likelihood of selecting a walker for various advances. Relationships between the ratings, the walkers’ self-reported frequencies of being approached, gait cues, and self-rated personality traits were examined. In the point-light condition, raters selected slow walkers with a short stride length and personality traits implying vulnerability as targets for inappropriate touching. In the full-view condition, the raters selected fashionably groomed or physically attractive walkers as sexual advance targets. These criteria corresponded partially with reported occurrences of advances. Awkward movement impression was suggested as a kinematic gait quality influencing sexual advance target choice.     

试论信息时代学报编辑的信息意识

信息时代为高校学报的发展带来了契机,同时对学报编辑提出了更高的要求,学报编辑工作的每一个环节都离不开信息,信息意识的强弱与学报的学术质量息息相关。研究新时期学报编辑信息意识的内涵,对高校学报事业的持续发展具有重要的意义。文章在阐述学报编辑信息意识内涵的基础上,提出了学报编辑具备信息意识的重要性及培养信息意识的基本对策。     

信息霸权的国际政治学思考--兼论美国的信息霸权

信息霸权是指信息技术发达国家利用技术优势(如制网权)妨碍、限制或压制他国对信息的自主动用,以谋求政治、经济和军事等利益.信息霸权巩固了信息技术发达国家在国际政治领域的主导地位,而数字鸿沟则对发展中国家维护信息主权形成强烈冲击.构建信息时代的信息主权和国家安全屏障要有战略眼光,既要及时维护国家利益,又要有长期的战略措施.

MODEL-ASSISTED HIGHER-ORDER CALIBRATION OF ESTIMATORS OF VARIANCE

In survey sampling, interest often centres on inference for the population total using information about an auxiliary variable. The variance of the estimator used plays a key role in such inference. This study develops a new set of higher‐order constraints for the calibration of estimators of variance for various estimators of the population total. The proposed strategy requires an appropriate model for describing the relationship between the response and auxiliary variable, and the variance of the auxiliary variable. It is therefore referred to as a model‐assisted approach. Several new estimators of variance, including the higher‐order calibration estimators of the variance of the ratio and regression estimators suggested by Singh, Horn & Yu and Sitter & Wu are special cases of the proposed technique. The paper presents and discusses the results of an empirical study to compare the performance of the proposed estimators and existing counterparts.     

基于价格的消费者信息搜寻过程研究

消费者在购买商品之前,信息搜集是一个必不可少的阶段。消费者的信息搜集过程是比较复杂的。文章通过构建信息搜寻模型,并对影响信息搜集的因素进行分析,认为产品的价格是影响信息搜集量及其持续时间的主要因素,即消费者在购买高价商品时花费的时间远远大于购买低价商品所花费的时间,并用实例进行验证。     

Proportional reversed hazard rate model and its applications

The purpose of this paper is to study the structure and properties of the proportional reversed hazard rate model (PRHRM) in contrast to the celebrated proportional hazard model (PHM). The monotonicity of the hazard rate and the reversed hazard rate of the model is investigated. Some criteria of aging are presented and the inheritance of the aging notions (of the base distribution) by the PRHRM is studied. Characterizations of the model involving Fisher information are presented and the statistical inference of the parameters is discussed. Finally, it is shown that several members of the proportional reversed hazard rate class have been found to be useful and flexible in real data analysis.
