Electrophysiological difference between the representations of causal judgment and associative judgment in semantic memory

Causally related concepts like “virus” and “epidemic” and general associatively related concepts like “ring” and “emerald” are represented and accessed separately. The Evoked Response Potential (ERP) procedure was used to examine the representations of causal judgment and associative judgment in semantic memory. Participants were required to remember a task cue (causal or associative) presented at the beginning of each trial, and assess whether the relationship between subsequently presented words matched the initial task cue. The ERP data showed that an N400 effect (250–450 ms) was more negative for unrelated words than for all related words. Furthermore, the N400 effect elicited by causal relations was more positive than for associative relations in causal cue condition, whereas no significant difference was found in the associative cue condition. The centrally distributed late ERP component (650–750 ms) elicited by the causal cue condition was more positive than for the associative cue condition. These results suggested that the processing of causal judgment and associative judgment in semantic memory recruited different degrees of attentional and executive resources.     

A general proof of consistency of heuristic classification for cognitive diagnosis models

The Asymptotic Classification Theory of Cognitive Diagnosis (Chiu et al., 2009, Psychometrika, 74, 633–665) determined the conditions that cognitive diagnosis models must satisfy so that the correct assignment of examinees to proficiency classes is guaranteed when non‐parametric classification methods are used. These conditions have only been proven for the Deterministic Input Noisy Output AND gate model. For other cognitive diagnosis models, no theoretical legitimization exists for using non‐parametric classification techniques for assigning examinees to proficiency classes. The specific statistical properties of different cognitive diagnosis models require tailored proofs of the conditions of the Asymptotic Classification Theory of Cognitive Diagnosis for each individual model – a tedious undertaking in light of the numerous models presented in the literature. In this paper a different way is presented to address this task. The unified mathematical framework of general cognitive diagnosis models is used as a theoretical basis for a general proof that under mild regularity conditions any cognitive diagnosis model is covered by the Asymptotic Classification Theory of Cognitive Diagnosis.     

5G远程超声诊断：提升医疗质量、安全和可及性

回顾了5G远程超声诊断的技术特点和应用趋势,剖析受检者、医护人员及社会的获益与风险,认为5G 远程超声诊断模式作为远程医疗全新应用,可以成为我国医联体资源共享的重要载体,有望改善医疗资源在基层和偏远地区时空分布不均,满足公共卫生疾病筛查、院前急救和隔离病房超声检查需求,提高医疗质量、安全和可及性。此外,针对衍生出的受检者-本地端-远程端三方权责关系治理挑战,以及未来直接面向消费者的健康管理新模式,提出运用医师多点执业制度、设备备案管理等措施予以规范的建议。     

新中国成立初期针灸推广实施路径与历史经验研究——以中央人民政府卫生部针灸疗法实验所为中心

新中国成立初期,在统一战线和发挥中医作用的要求下,针灸推广作为一项卫生工作被提上日程。中央人民政府卫生部针灸疗法实验所率先开展这项工作,开创了“理论学习+临床实习”的短期人才培训模式,在国内部分地区有计划、有组织地训练了一批针灸师资力量,并尝试通过实验研究为针灸推广提供科学理论支持。针灸疗法实验所推广针灸的工作为今后针灸推广在全国范围内进一步开展提供了可靠的人才培养模式,积累了宝贵经验,也是过渡时期中医力量参与新中国卫生事业建设的典型例证。

辅助生殖技术随访工作中的伦理原则探讨

随着人类辅助生殖技术 (assisted reproductive technology, ART) 的发展, 术后进行的定期随访工作在ART中的伦理学问题不断凸显, 有必要对其重视及规范。从伦理原则角度探讨了ART随访工作中存在的诸多伦理学问题, 即个人隐私权保护的缺失、知情同意的形式化、医源性多胎的伦理困境等。保密互盲、知情同意、保护患者、保护后代等伦理原则监督和规范ART近期及远期随访工作, 对于引导人类辅助生殖技术健康发展, 具有重大现实意义。     

项目特征曲线等值的抽样误差

现在,等值越来越受到各考试测验机构及测量学研究人员的重视,特别是项目反应理论等值的优越性更使他们有了信心。然而,很多人却没有注意到被试能力分布形态可能给等值结果带来的影响效果及程度。本研究以项目反应理论两级记分模型的项目参数等值在不同被试能力分布形态下的结果差异作为重点,探讨被试抽样偏差可能给项目特征曲线等值带来的误差问题。研究结果表明,被试能力分布形态会显著地影响项目参数等值的系数,特别地,能力分布的偏态系数与等值方程的截距存在显著的线性相关关系,但能力分布形态的变化对等值方程中斜率的影响并不明显     

康德实践理性的事实概念及其对自由的证明

康德实践理性的事实概念指的是道德律或道德律的意识,而道德律本身实际上是道德律的意识。道德律是某种自身肯定的东西,它作为事实肯定了纯粹实践理性的客观实在性,并通过理性的这一积极的概念,证明了它自身在实践上的客观实在性。正是通过道德律这一事实,在思辨哲学那里只具有消极性的自由的原因性的概念,在实践哲学中获得了积极的规定,也成为了一个“事实”。     

Testing the semantic differential as a model of task processes with the implicit association test

In this study, we examined the hypothesis that semantic judgment tasks share overlapping processes if they require processing on common dimensions but not if they require processing on orthogonal dimensions in semantic space (Osgood, Suci, & Tannenbaum, 1957). We tested the hypothesis with the implicit association test (IATl Greenwald, McGhee, & Schwartz, 1998) in three experiments. Consistent with the hypothesis, IAT effects (costs in reaction time because of incompatible response mapping between associated judgment tasks) occurred consistently when judgment tasks tapped into common semantic dimensions, whereas no IAT effect appeared when judgment tasks entailed processing on orthogonal semantic dimensions.     

The Effects of Collectivistic and Individualistic Values on Conflict and Decision Making: An Experiment in China

In an experiment with 80 participants in China, protagonists with opposing views in organizations that valued collectivism, compared to individualism, were found to develop cooperative goals, were confident that they could work, sought to understand, and demonstrated that they understood the opposing arguments, accepted these arguments as reasonable, and combined positions to create an integrated decision. The inductions comparing participants who valued harmony as a goal or a technique in which they pretended to agree were only partially effective and did not yield significant differences on conflict dynamics and outcomes. Findings challenge traditional theorizing that collectivistic values lead to conflict avoidance, and support recent arguments that strong, cooperative relationships promote the productive discussion of opposing views in decision making.
