论李鼎祚的《周易集解》

唐人李鼎祚的《周易集解》是现存最早的两汉象数易学文献,具有独一无二的文献价值。然李鼎祚的《周易集解》作为经学的解释文本是其所处时代学术思想的集中体现,他以两汉以来的象数易学及唐代易学中的"新义"反对孔颖达的《周易正义》,反映了唐代易学发展的新动向;李鼎祚的《周易集解》强烈地批判了王弼等玄学派易学"以无为本"的哲学观念,在整个易学哲学发展史中,成为沟通汉代易学与宋代易学的重要纽带。     

Numbers in social practices: the case of Tseltal Mayan children / Los números en las prácticas sociales: el caso de los niños y niñas mayas tseltales

Abstract

From a historical and cultural perspective as well as a critical ethnographic approach, this work analyses the numerical relationships that take place within the social practices of the Tseltal Mayan community. In this social group, children learn to identify numbers through the use of cultural artefacts and natural elements, as well as collaborating with adults and other children, bringing body, emotions and cognition into play. We describe how for Tseltal Mayan children, numbers constitute a way of naming the world.     

Division by zero in non-involutive meadows

Meadows have been proposed as alternatives for fields with a purely equational axiomatization. At the basis of meadows lies the decision to make the multiplicative inverse operation total by imposing that the multiplicative inverse of zero is zero. Thus, the multiplicative inverse operation of a meadow is an involution. In this paper, we study ‘non-involutive meadows’, i.e. variants of meadows in which the multiplicative inverse of zero is not zero, and pay special attention to non-involutive meadows in which the multiplicative inverse of zero is one.     

A Fuzzy Topsis Method for Prioritized Aggregation in Multi‐Criteria Decision Making Problems

Aggregation in a decision making environment requires the fusion of opinions of a group of decision makers. The group of decision makers are required to analyse a set of interrelated criteria that are usually measured on a linguistic scale. This process requires, in many instances, to capture experts experience, intuition and thinking that are traditionally expressed in a linguistic fashion rather than a numerical fashion. Furthermore, the necessity of considering the relationship between the criteria to the overall decision must be considered by the group of decision makers. This paper extends the application of fuzzy numbers, fuzzy relative importance scores (FRIS), fuzzy relative weights (FRW) and the fuzzy technique of order preference by similarity to ideal solution (TOPSIS) in prioritized aggregation. This extension provides a mean to systematically aggregate a group of decision makers' views for a set of interrelated criteria that are measured on a linguistic scale. First, an overview of the application of fuzzy numbers and the characteristics of aggregating fuzzy numbers in multi‐criteria decision making problems are presented. Then, the application of TOPSIS in fuzzy environments is presented. Next, past research is highlighted to present prioritized aggregation and the different aggregation operators' classes. Subsequently, a new prioritized aggregation method is presented. This method utilizes fuzzy TOPSIS with prioritized aggregation in fuzzy environments. Finally, the fuzzy prioritized aggregation method presented in this paper is applied on an actual case study. According to the results, the method presented in this paper provides a systematic approach to capture the uncertainty and imprecision associated with quantifying linguistic measurements in multi‐criteria decision making problems. Furthermore, it considers the relationship between the set of linguistically measured criteria undergoing prioritized aggregation in a fuzzy environment. Lastly, findings, conclusions and future work are presented. Copyright © 2016 John Wiley & Sons, Ltd.     

数字空间表征的在线建构：来自干扰情境中数字SNARC效应的证据

尽管已有研究发现数字以空间方式表征在人类记忆系统, 但是人脑如何完成数字的空间表征尚存争议。本研究两个实验在不同比例的数字字母(实验1)和不同比例的数字汉字(实验2)混合情境中考察了数字空间表征特点及其机制, 对上述争议进行了深入研究。结果发现：(1)当数字字母比例为“1 : 1”时, 数字加工中不出现SNARC效应。当数字字母比例为“1 : 6”和“6 : 1”时, 数字加工中均出现SNARC效应。即数字字母比例与数字SNARC效应之间呈倒“U”型关系。(2)数字汉字混合情境中数字汉字比例与数字SNARC效应之间同样呈倒“U”型关系。结果说明：(1)干扰刺激与数字混合呈现会影响数字SNARC效应。(2)干扰刺激加工对数字SNARC效应的影响受到数字与干扰刺激比例的调节, 且具有跨干扰材料的稳定性。研究结果意味着数字的空间表征是人类通过统计学习在线建构的, 支持了工作记忆理论。     

《周易》自然哲学与生命实践

《周易》蕴涵的自然哲学思想,可谓是一种以生命为隐喻,宇宙论、本体论、价值论统一的生成哲学,它基于道德实践与认识实践统一的生命实践。文章根据《周易》"经"、"传"本身之内涵,按现代哲学表述方法,从源于道德之宇宙论,三才圆通之本体论,知行不二之实践论,生成整体之方法论等方面,阐明中国式自然哲学的特性与意义。指出正是这种独特的自然哲学,不仅开启了中国文化超越的价值之源,为中国古代科学提供了形而上学基础,而且应在21世纪伟大历史转型和中西对话中,共同创造人类不同文化"殊途同归"、"和而不同"的世界生成之序。     

听觉通道下负数的低水平加工引起注意的SNARC效应

采用刺激探测任务,探讨了听觉通道下负数的低水平加工能否引起注意的SNARC效应。结果表明:(1)负数的低水平加工能够产生注意的SNARC效应,即线索为绝对值小的负数时,被试对左耳目标反应更快;线索为绝对值大的负数时,被试对右耳目标反应更快。(2)负数的加工所引起听觉空间注意的转移并不依赖于负数所在的情境,而仅通过其绝对值大小与空间表征发生关联。这一结论与视觉条件下所得到的结论不一致,并支持了系统发生论假说。     

Order information in verbal working memory shifts the subjective midpoint in both the line bisection and the landmark tasks

A largely substantiated view in the domain of working memory is that the maintenance of serial order is achieved by generating associations of each item with an independent representation of its position, so-called position markers. Recent studies reported that the ordinal position of an item in verbal working memory interacts with spatial processing. This suggests that position markers might be spatial in nature. However, these interactions were so far observed in tasks implying a clear binary categorization of space (i.e., with left and right responses or targets). Such binary categorizations leave room for alternative interpretations, such as congruency between non-spatial categorical codes for ordinal position (e.g., begin and end) and spatial categorical codes for response (e.g., left and right). Here we discard this interpretation by providing evidence that this interaction can also be observed in a task that draws upon a continuous processing of space, the line bisection task. Specifically, bisections are modulated by ordinal position in verbal working memory, with lines bisected more towards the right after retrieving items from the end compared to the beginning of the memorized sequence. This supports the idea that position markers are intrinsically spatial in nature.     

外框数目、线索数目和线索类型对返回抑制的影响

采用被试内重复测量设计和经典的线索—靶子实验范式,考查了外框数目（4和8）、线索数目（1和3）、不同线索类型（on-off线索（即线索出现后消失）、onset线索（即线索持续呈现））对返回抑制的影响,发现靶子潜在位置数目越多反应时越长,返回抑制量越小;线索数目越少反应时越长,返回抑制量越大;onset线索反应时长于on-off线索,onset线索产生的返回抑制量大于on-off线索。这表明空间工作记忆负载和记忆痕迹会影响返回抑制。
