How Critical is the Dialectical Tier?

This paper addresses the issue of the relationship between Ralph Johnson’s idea of dialectical tier and the critical scrutiny function in argument. We first give a concise articulation of the critical view of argument, and then probe into both the apparent similarities and deep discrepancies between the critical view of argument and Johnson’s views on the dialectical tier and manifest rationality. On that basis, we disprove the conjecture that the presence of a dialectical tier indicates that the thesis in argument is critically established. However, we also urge to bridge together the critical view of argument and Johnson’s theory of argument, and thereby to make the dialectical tier critical in nature. We argue that this could be a promising proposal, and conclude with some remarks on exploring the critical dimension within our current study of argument.     

数学应用题中语言成分模型的构建—— 多元随机效应项目反应理论模型的运用

数学应用题中的语言成分可能对被试问题解决过程产生复杂影响。通常, 这种影响对所有被试并非完全一致, 而是具体数学题目特征与特定被试的认知特性之间交互作用的结果。本研究采用多元随机效应项目反应理论模型的建模方法, 分析了数学应用题中语言成分对问题解决过程的影响。该方法的优势在于它不仅分析了语言成分对数学问题解决过程的平均效应, 同时给出了相应的随机效应, 揭示了相应成分对不同个体问题解决过程的具体影响程度。结果表明, 较难的项目倾向于单词更多, 命题密度更高, 要求对图/表信息进行编码和转译, 或者根据问题表述生成数学公式。项目命题密度影响效应存在着显著的个别差异。项目命题密度对能力较低的被试的影响高于对能力较高的被试的影响。     

当代农民工感知社会支持、自尊和主观幸福感的关系

本研究以600名农民工为被试,采用自编的农民工感知社会支持情景问卷以及修订的自尊量表、农民工主观幸福感问卷,以探讨农民工感知社会支持、自尊与主观幸福感的关系,并考查农民工自尊在其感知社会支持与主观幸福感之间的中介作用。结果表明：（1）高自尊水平农民工的主观幸福感及其各维度、感知社会支持都极其显著地高于低自尊农民工;（2）自尊水平与主观幸福感及各维度、感知社会支持水平之间存在极其显著的正相关关系;（3）感知社会支持、自尊与主观幸福感显著两两正相关;（4）自尊在感知社会支持基础上对主观幸福感及两个维度回归效应显著,为二者之间重要的中介变量。     

Lightness constancy and illumination discounting

Contrary to the implication of the term "lightness constancy", asymmetric lightness matching has never been found to be perfect unless the scene is highly articulated (i.e., contains a number of different reflectances). Also, lightness constancy has been found to vary for different observers, and an effect of instruction (lightness vs. brightness) has been reported. The elusiveness of lightness constancy presents a great challenge to visual science; we revisit these issues in the following experiment, which involved 44 observers in total. The stimuli consisted of a large sheet of black paper with a rectangular spotlight projected onto the lower half and 40 squares of various shades of grey printed on the upper half. The luminance ratio at the edge of the spotlight was 25, while that of the squares varied from 2 to 16. Three different instructions were given to observers: They were asked to find a square in the upper half that (i) looked as if it was made of the same paper as that on which the spotlight fell (lightness match), (ii) had the same luminance contrast as the spotlight edge (contrast match), or (iii) had the same brightness as the spotlight (brightness match). Observers made 10 matches of each of the three types. Great interindividual variability was found for all three types of matches. In particular, the individual Brunswik ratios were found to vary over a broad range (from .47 to .85). That is, lightness matches were found to be far from veridical. Contrast matches were also found to be inaccurate, being on average, underestimated by a factor of 3.4. Articulation was found to essentially affect not only lightness, but contrast and brightness matches as well. No difference was found between the lightness and luminance contrast matches. While the brightness matches significantly differed from the other matches, the difference was small. Furthermore, the brightness matches were found to be subject to the same interindividual variability and the same effect of articulation. This leads to the conclusion that inexperienced observers are unable to estimate both the brightness and the luminance contrast of the light reflected from real objects lit by real lights. None of our observers perceived illumination edges purely as illumination edges: A partial Gelb effect ("partial illumination discounting") always took place. The lightness inconstancy in our experiment resulted from this partial illumination discounting. We propose an account of our results based on the two-dimensionality of achromatic colour. We argue that large interindividual variations and the effect of articulation are caused by the large ambiguity of luminance ratios in the stimulus displays used in laboratory conditions.     

作为程序与属性的论辩术——析当代论证理论中“论辩术”视角的差异解读

当代论证理论中"论辩术"之理论视角存在着两种不同的解读方式。一种以语用论辩术理论为代表,将"论辩术"外化为论证活动的程序与规则,另一种以非形式逻辑理论为代表,将"论辩术"内化为论证成果的属性或品质。对这两种"论辩术"的解析将揭示出语用论辩术与非形式逻辑在规范性理论之建构与情境性实践之关注间的深层差异,同时也展现出其自身在谬误研究及论证界定等当代论证研究议题上的理论潜力。     

How do people apprehend large numerosities?

People discriminate remarkably well among large numerosities. These discriminations, however, need not entail numerical representation of the quantities being compared. This research evaluated the role of both non-numerical and numerical information in adult judgments of relative numerosity for large-numerosity spatial arrays. Results of Experiment 1 indicated that judgments of relative numerosity were affected by the amount of open space in the arrays being compared. Further, the accuracy of verbal estimates of the numerosities of the arrays made upon completion of the comparison task bore little relation to performance on that task. Experiment 2, however, showed that numerical estimates for individually presented arrays were affected in much the same way by open space within or around the edges of the array as were the comparative judgments examined in Experiment 1. The findings suggest that adults heuristically utilize non-numerical cues as well as numerical information in apprehending large numerosities.     

急性心肌梗死发病年轻化的因果分析

越来越多的中青年人因急性心肌梗死住院甚至猝死,其发病具有原因和结果的必然联系。过劳、不良生活习惯、吸烟、大量饮酒等原因都会使冠状动脉内斑块形成或冠状动脉痉挛而诱发急性心肌梗死。患者及医务工作者都应针对病因及发病机制积极治疗并有效预防,从而提高全民的心血管健康水平。

从能量观疾病

能量在机体的各种离子、分子、细胞、器官、组织、系统间协调分布,共同维持着健康状态。某一病因作用于人体后,“协调分布”会被不同程度地打破,当超过一定的阈值,就会产生疾病。对于人体,各种能量的直接表现形式和能量的携带者——各种营养物质,都与疾病之间有着千丝万缕的联系。从“能量”角度,我们既可进一步探讨尚未阐述清楚的疾病发生机制,又可以设计更为完美的治疗方案与医学仪器。
