关于现代中医学研究的几点思考

以中医学的研究目的为线索,从中医学研究的历史观、现代中医研究的得失观、今后中医研究应当明确的几个问题的发展观三个方面对中医的研究目的进行了探讨,提出今后中医药研究应当明确的问题有：否定是中医学研究的突破口;政策指导是中医学研究的保障;求实是中医学研究的灵魂;研究成果向临床实践转化是中医学研究的生命。     

和而不同,相辅相成——制度与道德相关性的哲学辨析

在社会发展实践中,制度与道德之间有着相互交叉、相互促进、相互转化的错综复杂的关系。制度的生成、演化、运行背后有着强烈的道德意蕴,道德本身所具有的规范性也不可避免地体现出制度的色彩。制度的道德依托使得制度的价值指向更加积极和明确,道德的制度支持则会促进道德的有效实现和践履。但制度和道德毕竟是各自独立的范畴,有着各自内涵的确定性,不能不适当地淡化两者之间的差别,两者之间是互补而不是替代的关系。

Trained interpretive bias and anxiety

The relationship between anxiety and interpretive bias has been studied extensively, but the causal direction of this relationship remains largely unexplored. Do negative interpretations cause anxiety or is anxiety the cause of negative interpretations? Or are the two mutually reinforcing? The present study addressed this issue by experimentally inducing either a negative or a positive interpretive bias using Mathews and Mackintosh' [(2002). Induced emotional interpretation bias and anxiety. Journal of Abnormal Psychology, 109, 604-615] training paradigm and then examining its impact on state anxiety and anxiety vulnerability. In addition, it was investigated as to whether the interpretive bias was trained implicitly. Results indicated that style of interpreting could be manipulated. That is, when confronted with ambiguous information after the training, participants (n=118) interpreted this information congruent with their (positive or negative) training condition. Data on the issue of implicitness showed that participants tended to be explicitly aware of the valence of their training stimuli. Effects of trained interpretive bias on anxiety were only marginal and absent on anxiety vulnerability. It appears that interpretive bias can be trained reliably, but its effects on mood and vulnerability require further explanation.     

基于YAH（You—Are-Here）地图定向中的方位效应

目的：研究基于YAH地图进行方位判断时是否存在方位效应及其表现形式。方法：90名被试分为三组参加三个被试内设计实验,实验一为基于YAH地图的绝对朝向判断,实验二为基于YAH地图的相对方位判断,实验三为不同绝对朝向条件下（失匹配）的相对方位判断。结果：绝对朝向判断中存在绝对朝向效应及北优势效应,反应时上表现为“0°〈（90°／180°／270°）〈（45°／135°／225°／315°）”;相对方位判断中存在相对方位效应,表现为反应时“（0°／90°／180°／270°）〈（45°／135°／225°／315°）”;失匹配条件下相对方位效应表现为“0°〈（90°／180°／270°）〈（45°／／315°）〈（135°／225°）”,相对方位效应模式不受绝对朝向影响。结论：基于YAH地图定向存在绝对朝向效应及相对方位效应,相对方位效应不受绝对朝向的影响。     

Measuring preschool cognitive growth while it's still happening: The Learning Express

Educators need accurate assessments of preschool cognitive growth to guide curriculum design, evaluation, and timely modification of their instructional programs. But available tests do not provide content breadth or growth sensitivity over brief intervals. This article details evidence for a multiform, multiscale test criterion-referenced to national standards for alphabet knowledge, vocabulary, listening comprehension and mathematics, developed in field trials with 3433 3–5¹/₂-year-old Head Start children. The test enables repeated assessments (20–30 min per time point) over a school year. Each subscale is calibrated to yield scaled scores based on item response theory and Bayesian estimation of ability. Multilevel modeling shows that nearly all score variation is associated with child performance rather than examiner performance and individual growth-curve modeling demonstrates the high sensitivity of scores to child growth, controlled for age, sex, prior schooling, and language and special needs status.     

Age-related Assessment of Postural Control Development: A Cross-sectional Study in Children and Adolescents

Abstract

The aim of this study was to outline an age-dependent range of posturography measures obtained from healthy children. One hundred and fifty healthy 4–18-year-old children underwent video Head Impulse Test and static posturography testing. Surface, length and power spectra values were compared between each group of pupils and 32 healthy adults. As well as a significant (p?<?0.025) increase in surface and length, when compared to healthy adults, increased values within the low/middle frequency domain and within the high frequency domain were also observed in 4–13 and 4–7-year-old children, respectively. In conclusion, although the nature of postural control development remains largely undetermined, this study represents a first attempt to outline an age-dependent normal range of the relative contribution of inputs in typically developing children.     

The effects of age on the contributions of head and eye movements to scanning behavior at intersections

The current study was aimed at evaluating the effects of age on the contributions of head and eye movements to scanning behavior at intersections. When approaching intersections, a wide area has to be scanned requiring large lateral head rotations as well as eye movements. Prior research suggests older drivers scan less extensively. However, due to the wide-ranging differences in methodologies and measures used in prior research, the extent to which age-related changes in eye or head movements contribute to these deficits is unclear. Eleven older (mean 67 years) and 18 younger (mean 27 years) current drivers drove in a simulator while their head and eye movements were tracked. Scans, analyzed for 15 four-way intersections in city drives, were split into two categories: eye-only (consisting only of eye movements) and head + eye (containing both head and eye movements). Older drivers made smaller head + eye scans than younger drivers (46.6° vs. 53°), as well as smaller eye-only scans (9.2° vs. 10.1°), resulting in overall smaller all-gaze scans. For head + eye scans, older drivers had both a smaller head and a smaller eye movement component. Older drivers made more eye-only scans than younger drivers (7 vs. 6) but fewer head + eye scans (2.1 vs. 2.7). This resulted in no age effects when considering all-gaze scans. Our results clarify the contributions of eye and head movements to age-related deficits in scanning at intersections, highlight the importance of analyzing both eye and head movements, and suggest the need for older driver training programs that emphasize the importance of making large scans before entering intersections.     

医学本体论的当代转向——医学教育模式改革的前提性问题

医学本体论,是指“关于医学的”最根本的根据、本质和基础的理论,它是医学赖以存在的本质基础和逻辑根据。当代医学本体论的转向是从人体学本体论向人学本体论的转变。实现这一转变的主要途径在于医学教育模式的改革,而其前提性问题,则是建构人学本体论思想。
