新尝试"假设法脑出血测量"与常用方法的对比

介绍一种CT脑血肿体积测量的新方法-假设法.制作水模进行CT扫描,分别用CT脑出血测量之假设法与多田公式法、CT定量法对其测量,比较结果的准确性.该方法较多田公式法、CT定量法更便捷准确.此假设法,计算简单、快速、准确,比多田公式法、CT定量法更具优势.     

拓展后的GGUM在LOT-R中的适用性分析

该研究对拓广等级展开模型（GGUM）进行了拓展,取消GGUM中关于主观反应类别阈限对称的假设,并将拓展之后的新模型和GGUM同时用于生活取向测验修订版（LOT-R）的被试反应数据分析,采用新编的单项目、两项目对和三项目组χ2/df计算程序计算和比较新模型和GGUM在该测验数据上的拟合差异。结果显示,新编程序与Stark等人开发的MODFIT程序具有同样的有效性,新模型在这些指标上的值显著小于GGUM,并且均小于3,表明新模型较GGUM更适合于分析LOT-R的反应数据,说明新模型更适用于分析具有多个评定等级的人格测验数据。根据以上结果,该研究认为,未来人格测验的数据分析应该使用没有对主观反应类别阈限进行对称限定的新拓展的模型更合理。     

付出-回馈工作压力模型：西方国家十年来研究的回顾与评析

付出&;#8722;回馈工作压力模型(Effort-Reward Imbalance, ERI)以社会交换理论为视角, 从付出、回馈、过度投入三个方面探讨了工作压力的形成机制和作用机理。在对近十几年来有关ERI模型实证研究文献的梳理和分析的基础上, 系统地介绍ERI模型的理论基础、模型的适用性验证、相关变量探索及模型拓展等, 发现目前的ERI模型具有较好的解释力和适用性, 但是模型的中间变量及交互假设有待进一步探索, 付出、回报失衡值的计算方法尚需进一步优化。     

On the theoretical error bound for estimating psychometric functions

The theoretical limits to the amount of error, or the Cramer-Rao bounds, were derived for estimating psychometric functions. These theoretical error bounds were compared with the variability of psychometric functions estimated from human as well as computer-simulated observers. For the simulated observers, due to the limited efficiency of the sampling strategies, including the placement of the signals and the distribution of the trials, the variances of the estimated parameters are seven times the theoretical bound for threshold and 22 times that for slope. For the human observers, the variance is 18 times the theoretical bounds for threshold and 80 times that for slope. Therefore, a major portion of the variances (60% for threshold and 73% for slope) for the human observers is associated with factors other than sampling strategies. Further improvement of the accuracy for estimating psychometric functions will depend on not only optimizing the sampling strategy, but also better understanding the various sources of error related to the behavior of human observers.     

当代中学生性别角色发展现状调查分析

为揭示我国中学生性别角色的发展现状以及发展中的问题和特点,本研究采用最新本土化的性别角色量表(CSRI-50)对初中生、高中生进行调查,发现:各年级段的双性化、未分化、单性化(男性化与女性化)比例各约占30%,双性化替代单性化成为中学生性别角色发展的新趋势,未分化现象也极为普遍;我国青少年双性化发展较国外已提前至青春期,初三、高三升学、恋爱等重大生活事件对个体的适应和发展提出更高要求,从而催生大量双性化并大幅减少未分化,这两个个年级可能既是双性化发展又是抑制未分化的重要时期;此外,中学女生双性化发展明显优于男生。     

人文医学的视角：裘法祖误诊误治思想初探——兼论医学伦理道德

本文结合裘法祖的相关论述,对裘法祖的误诊误治思想进行梳理勾连。认为裘法祖这一重要医学思想内涵是要勇于总结医学当中的误诊误治、老专家要“真心帮助青年人”,要学习国外经验,但也不能枉自菲薄,这一思想在当代医学医德教育当中有重要的启示意义。     

当今中国伦理学的现象学还原

当前我们的伦理学有时因为缺乏情感而过于客观,有时因为讲究亲情而过于主观,时常处于主客二元分裂状态.根据现象学的主客不分立场,推进中国伦理学创新,最要紧的是实现胡塞尔所期待的现象学还原.     

Moderating effect of Zhong Yong on the relationship between creativity and innovation behaviour

The present study examined the moderating effect of Zhong Yong on the relationship between perceived creativity and innovation behaviour in Chinese companies. A total of 273 paired questionnaires were collected with employee self-rated creativity and Zhong Yong and supervisor-rated innovation behaviour. The results show that for people higher on Zhong Yong, their creativity was not correlated with innovation behaviour; for people less immersed in Zhong Yong, this correlation is significant. This finding provides a new insight into the effects of Zhong Yong on the creativity-innovation behaviour transformation processes. The implications for future research are also discussed.     

论马克思对康德自由概念的感性证明

自由是贯穿整个西方文化的价值目标,是主体之为主体的根据,它发展到德国古典哲学时期已经取得了巨大成果,康德和马克思的自由观就宛如德国近代自由思想的两个点:康德自由概念的核心是自由意志,并且它是纯粹理性的唯一事实,但对它的证明始终是个问题;马克思对康德的"自由"进行了感性证明。
