亚健康中抑郁程度人群分布特点的对应分析

为了分析亚健康人群抑郁的不同表现程度与不同人口学资料的关系,采用"亚健康状态的测量及诊断标准研究"课题组调查的中国人亚健康资料,利用对应分析对抑郁表现因子总分的不同等级与不同的年龄、婚姻、职业和学历的关系进行分析。结果显示,20岁～30岁、未婚、学生和大专及以上学历主要表现为中重度抑郁倾向,31岁～40岁、已婚、专业人士和高中专学历主要表现为中度抑郁倾向,41岁～60岁、工人、农民和初中以下学历的抑郁倾向较轻,结论为亚健康人群的心理不适,特别是抑郁倾向,主要集中在年龄较轻、学历较高的专业人士和白领人群当中,还包括大学生群体,我们应该针对这些群体采取相应的措施减轻他们的心身不适。     

医学模式的转变与对腰痛患者实施认知行为治疗

随着医学模式从生物医学模式向生物-心理-社会医学模式的转变,心理社会因素对腰痛患者疼痛的影响亦日益引起社会的普遍关注.从心理社会因素对腰痛患者疼痛的影响探讨医学模式转变的必要性以及给腰痛患者实施认知行为治疗的可行性.     

论技术主义对人类道德责任的消解

技术主义流行于 2 0世纪的工业社会之中 ,成为支配人们思维方式和生活方式的意识形态。“知识就是力量”的技术主义知识立论 ,在学理层面上消解了人的道德责任 ;技术意志取代人的自由意志 ,在伦理层面上消解了人的道德责任 ;社会生产领域和政治领域的标准化和科层制 ,在操作层面上颠覆了人的道德责任 ;人与自然关系问题上的人类中心主义拒斥了对自然的道德责任。     

Auditory localization in teleoperator and virtual environment systems: ideas, issues, and problems.

The increasing availability and use of advanced high-tech human-machine interfaces raise many interesting questions about what information should be presented to each sensory modality and how the information should be coded for a given modality. In this paper, attention is confined to the auditory component of the interface and, more specifically, to auditory localization. Both teleoperator systems and virtual-environment systems are considered, and attention is focused upon the opportunities and difficulties associated with the use of unnatural perceptual cues in these systems. Of central interest in this discussion is the use of such cues to improve resolution and thereby obtain systems with superlocalization capabilities.     

Manual discrimination and identification of length by the finger-span method

Experiments were conducted on length resolution for objects held between the thumb and fore-finger. The just noticeable difference in length measured in discrimination experiments is roughly 1 mm for reference lengths of 10 to 20 mm. It increases monotonically with reference length but violates Weber's law. Also, it decreases when the subject is permitted to maintain a constant finger span between trials; however, it tends to increase when the nondominant hand is used. As would be expected from studies of other stimulus dimensions in other sense modalities, resolution is considerably poorer in identification experiments than in discrimination experiments. For stimulus sets that cover a broad range (90 mm), the total information transfer is roughly 2 bits; for those that cover a relatively small range (18 mm), it is roughly 1 bit. The data are analyzed and interpreted using analysis techniques and models that have been used previously in studies of audition (e.g., Durlach & Braida, 1969).     

Analysis of the unique cue in configural discriminations

Four experiments used an autoshaping procedure with pigeons to investigate the basis of configural discriminations. The elements of both a negative patterning (A+, B+, AB-) and a conditional discrimination (AC+, BD+, AD-, BC-) were paired, in a second-order procedure with two new key lights, X and Y. Responding was then tested to X and Y presented in compound with each other and with A and B. The pattern of responding to compounds containing X and Y was like the pattern of responding to compounds containing their associates, A and B. This suggests that A and B can be replaced by their associates without disrupting responding to their compounds. Because X and Y are physically different from A and B, this in turn suggests that any unique cue controlling responding to their compounds does not depend on the physical presence of the component stimuli. Instead the unique stimulus appears to arise from the joint activation of memory representations.     

直觉和分析在不同任务条件下的逃生决策效果

目的：探讨针对简单和复杂逃生任务时, 直觉和分析在不同判断依据条件下的逃生决策效果。方法：采用两个主实验和两个预备实验。实验一和实验二的被试人数分别为：85人和87人。两个主实验均采取2 (思维方式：直觉和分析) × 2 (判断依据：简单和复杂)组间实验设计。主要结果：(1)针对简单逃生任务, 直觉组和分析组在不同判断依据条件下的逃生决策效果差异不明显; (2)针对复杂逃生任务, 在简单判断依据条件下分析决策优于直觉决策; 在复杂判断依据条件下直觉决策优于分析决策。主要结论：直觉性和分析性逃生决策的效果主要与决策任务的复杂程度有关, 而与判断依据的复杂程度关系不大。     

Human–Robot Interaction in the Context of Simulated Route Reconnaissance Missions

The goal of this research was to examine the ways in which human operators interact with simulated semiautonomous unmanned ground vehicles (UGVs), semiautonomous unmanned aerial vehicles (UAVs), and teleoperated UGVs (Teleop). Robotic operators performed parallel route reconnaissance missions with each platform alone and with all three platforms. When given all three platforms, participants failed to detect more targets than when given only the UAV or UGV; they were also less likely to complete their mission in the allotted time. Target detection during missions was the poorest with the Teleop alone, likely because of the demands of remote driving. Spatial ability was found to be a good predictor of target-detection performance. However, slowing sensor feed video frame rate or the imposition of a short response latency (250 ms) between Teleop control and Teleop reaction failed to affect target-detection performance significantly. Nevertheless, these video image manipulations did influence assessment of system usability.

亚健康的相关概念比较

结合医学的发展轨迹,在对相关文献进行系统疏理中发现,一些曾经或正在风靡的病症概念中或系统或散在地涉及了亚健康的相关问题。就亚健康与慢性疲劳综合征、神经衰弱、神经官能症及中医未病等相关概念作一比较分析,希冀有助于亚健康概念与范畴的研究及确定。
