Combinatorial data analysis: Association and partial association

A combinatorial data analysis strategy is reviewed that is designed to compare two arbitrary measures of proximity defined between the objects from some set. Based on a particular cross-product definition of correspondence between these two numerically specified notions of proximity (typically represented in the form of matrices), extensions are then pursued to indices of partial association that relate the observed pattern of correspondence between the first two proximity measures to a third. The attendant issues of index normalization and significance testing are discussed; the latter is approached through a simple randomization model implemented either through a Monte Carlo procedure or distributional approximations based on the first three moments. Applications of the original comparison strategy and its extensions to partial association may be developed for a variety of methodological and substantive tasks. Besides rank correlation, we emphasize the topics of spatial autocorrelation for one variable and spatial association between two and mention the connection to the usual randomization approach for one-way analysis-of-variance.     

康德哲学与企业文化

本文分析了中国当前企业文化的三种类型即官商、儒商和佛商,指出佛商流行于华南一带,是目前最有生机活力的一种企业文化,但这种生机活力是由于解构一切规范带来的,具有投机性,不具有积极建设性,对市场经济规律没有自觉意识,尤其对于赚钱的目的性不明确,背后受本能欲望的支配;康德哲学和西方基督教文化在这方面的启示是能够提供一种终极关怀,实践理性的道德自律为人的生存指明了一种理想目标。因此,当代企业文化的发展前景依赖于个人自由意志的确立和建立理性的规范,赚钱的目的应归结到完成自由人格。     

遗忘症患者外显与内隐记忆分离的实验研究：自由回忆与再认任务

采用WMS－CR和MMSE筛选了9名遗忘症患者,采用自由回忆和再认两项任务观察了他们及正常对照组的外显记忆。结果发现：遗忘症患者两项外显记忆任务操作呈分离现象,自由回忆任务操作明显受损,再认任务的操作尽管较对照组低,但与对照组差异未达显著性水平。推论;①外显记忆受患者损伤的颞叶或间脑结构调节。②再认任务至少包含两种性质不同的潜在加工过程,一种为意识性重组加工,另一种为无意识自动加工,两者相互独立地贡献再认任务的操作。正常人意识性重组加工的贡献占优势,掩盖了无意识的作用。遗忘症患者意识性重组加工损伤,无意识自动加工部分代偿作用。③先前研究未对遗忘症患者进行认知功能的筛选,患者对再认障碍可能源于其他认知功能障碍,而非记忆障碍之故。     

Coding categorical and coordinate spatial relations in visual–spatial short-term memory

Four experiments explored the coding of categorical and coordinate spatial relations in visual–spatial short-term memory (VSSTM). Participants judged whether two stimuli presented successively on a computer screen were the same or different. On positional change trials the two stimuli differed in the position of one element. Positional changes were of two types, coordinate and categorical. On coordinate trials the position of one element changed by a small amount, but retained the categorical relationships (above, below, left of, right of) to all other elements. On categorical trials one element moved by the same amount but additionally changed its categorical relationship to one of the other elements (e.g., changed from below to above). Participants detected categorical changes more accurately than coordinate changes when the elements were independent locations marked by squares, indicating that the categorical relationships amongst the squares were encoded in memory. Furthermore, this categorical advantage was unmodulated by either the suppression of articulation (Experiment 2) or by the requirement to retain either colour–position associations or positions only (Experiment 3). When the elements to be remembered were the vertices of simple outline polygons (Experiment 4) there was no categorical advantage, establishing the effect as spatial in nature. Contrary to predictions derived from Postma and De Haan (1996) Postma, A. and De Haan, E. H. 1996. What was where? Memory for object locations. Quarterly Journal of Experimental Psychology, 49A: 178–199. [Crossref], [Web of Science ®] , [Google Scholar], the employment of categorical relations appears not to be specifically linked to either verbal coding or to the requirement to associate objects with positions. The results suggest that the categorical relations are an intrinsic property of the representation of spatial configurations.     

Introduction: The Role of Process Metaphysics in Our World of Science

This article applies the analytic rigor of philosophy to the vexed topic of business strategy, and uses the objective, public evidence of business strategy as an existence proof for the possibility of free will and purpose in the private realm of subjective intentionality. The first part distinguishes three types of intentionality in philosophy—purposive intentionality, referential intentionality, and the problematic intentionality of a godlike, miraculous “inner intender.” After rejecting this third type of intentionality, and noting that its rejection saves the first two types of intentionality from guilt by association, the second part draws parallels with three types of strategy in business: purposive, referential, and godlike. The first defines the goals and objectives of a company; the second picks out and targets consumers in market driven strategy; and the third, with the help of philosophical reflections, demands a rethinking of the function of leadership without reliance on a single, godlike leader. In the third part of this article, the existence proof from the public world of business is used to shed light on the possibility of intentionality in the private world of subjective intentionality. Finally, the article draws conclusions for its three audiences: for the philosophers, with credit to Nietzsche who saw it all, a greater clarity about intentionality and free will; for business people, greater clarity about the importance of purposiveness and strategic intent; and for business philosophers, a demonstration showing how—through strategy and intentionality—we can both create value and give meaning to the lives of our employees, ourselves, and our customers.     

积极情景线索对内隐攻击性的影响

通过向被试呈现代表积极情景线索的材料(一段含有互助、和谐信息的公益短片),运用内隐联想测验(IAT)范式,从内隐社会认知的角度来研究积极情境线索对个体内隐攻击性的影响,并分析这种影响是否具有性别差异。结果表明:未观看积极情景线索材料的被试表现出显著的内隐攻击性,而观看积极情景线索材料的被试的内隐攻击性不显著;积极情景线索的主效应显著,且这一效应不存在性别差异。这说明,积极情景线索能有效抑制个体的内隐攻击性,并支持自我攻击信念IAT是测量个体内隐攻击性的有效工具。     

论述理解中逻辑有效与逻辑无效条件推理的研究

句法理论和心理模型理论是解释论述理解中逻辑有效 (如MP)与逻辑无效 (如AC)条件推理机制的两种不同观点。本研究通过两项实验旨在对这两种理论加以检测。实验要求被试阅读遵循MP或AC形式的故事后对故事结论的正确性做出判断。结果表明 ,在论述理解中 ,条件前提的语义联系强度影响MP推理 ;深思熟虑对MP和AC推理均产生影响。研究结果支持心理模型理论。     

Indeterminism, Explanation, and Luck

I first adumbrate pertinent aspectsof Robert Kane's libertarian theory of free choice oraction and an objection of luck that has been levelledagainst the theory. I then consider Kane's recentresponses to this objection. To meet these responses,I argue that the view that undetermined choices (ofthe sort implied by Kane's theory) are a matter ofluck is associated with a view about actionexplanation, to wit: when Jones does A and hisdoing of A is undetermined, and when hiscounterpart, Jones*, in the nearest possibleworld in which the past and the laws are held constantuntil the moment of choice does B instead, thereis no explanation (deterministic or indeterministic)of the difference in outcome – Jones's A-ing butJones*'s B-ing – in terms of prior reasonsor motives of either agent. Absence of such anexplanation is one crucial factor that underliesthe charge that Jones's A-ing and Jones*'sB-ing are matters of luck. I argue that thissort of luck is incompatible with responsibility.     

Nonparametric IRT: Testing the bi-isotonicity of isotonic probabilistic models (ISOP)

Nonparametric tests for testing the validity of polytomous ISOP-models (unidimensional ordinal probabilistic polytomous IRT-models) are presented. Since the ISOP-model is a very general nonparametric unidimensional rating scale model the test statistics apply to a great multitude of latent trait models. A test for the comonotonicity of item sets of two or more items is suggested. Procedures for testing the comonotonicity of two item sets and for item selection are developed. The tests are based on Goodman-Kruskal's gamma index of ordinal association and are generalizations thereof. It is an essential advantage of polytomous ISOP-models within probabilistic IRT-models that the tests of validity of the model can be performed before and without the model being fitted to the data. The new test statistics have the further advantage that no prior order of items or subjects needs to be known.     

A further note on freeman's measure of association

This note extends and elaborates Hubert's attempt to provide an interpretation of Freeman's measure of association,. The measure is used in a a contingency table when observations are ordered on one variable and unordered on the other. No attempt is made explore the distribution of.
