Serendipity in the Theater: Maude Adams as James M. Barrie's American Muse

A special niche in theatre history is addressed to begin to fill a void in the contemporary creativity literature. The present essay focuses on Maude Adams and James M. Barrie in an attempt to demonstrate that, serendipitously, Adams initially impacted Barrie's creative process, and thereafter became his platonic source of inspiration for the plays he created for her, meriting the belated title of muse. Set change theory is underscored as a plausible cognitive explanation for Barrie's illumination. The psychoanalytic theory of transference is proposed as an underlying mechanism for facilitating the change of mental set during the incubation stage. A brief discussion on a selective theoretical integration from the fields of cognitive psychology, psychoanalysis, and neuroscience is followed by conclusions.     

Light Affine Set Theory: A Naive Set Theory of Polynomial Time

In [7], a naive set theory is introduced based on a polynomial time logical system, Light Linear Logic (LLL). Although it is reasonably claimed that the set theory inherits the intrinsically polytime character from the underlying logic LLL, the discussion there is largely informal, and a formal justification of the claim is not provided sufficiently. Moreover, the syntax is quite complicated in that it is based on a non-traditional hybrid sequent calculus which is required for formulating LLL.In this paper, we consider a naive set theory based on Intuitionistic Light Affine Logic (ILAL), a simplification of LLL introduced by [1], and call it Light Affine Set Theory (LAST). The simplicity of LAST allows us to rigorously verify its polytime character. In particular, we prove that a function over {0, 1}* is computable in polynomial time if and only if it is provably total in LAST.     

Tackling conflict: a beyond opposites approach

The issue of conflict is pervasive to most human undertakings at both individual/intra level and group level. Conflicts are the source of internal and external suffering. It has been argued by many authors that although humans have advanced in the technological sphere tremendously and managed to find solutions to countless scientific and material challenges, their ability to effectively resolve internal and external aspects of conflicts remains elusive. Given the level of pain and suffering that can derive from both psychological and social conflicts, it can be argued that any advances in helping improve the resolution of conflicts can have immense benefits in alleviating human suffering making this issue a very worthwhile area of study. Accordingly this paper aims to describe a developing counselling methodology for addressing conflict. The methodology, which was originally inspired by Fuzzy Logic, adopts a cognitive behavioural therapy (CBT) perspective despite awareness of its limitations. The paper traces the origins of the methodology and the areas within counselling it could be applied to. The paper concludes with recommendations regarding the relevance of this approach to an increasingly multicultural environment.     

情绪状态对不同年龄儿童定势转换的影响

采用情绪影片引发情绪的方法,考察64名8~12岁儿童在正负情绪状态下定势转换能力的表现。研究为4(年龄)×2(情绪)×3(重复转换条件:重复、短时转换、长时转换)3因素重复测量混合设计。结果表明,情绪状态对任务转换产生了影响,可能是积极情绪比消极情绪对任务定势的长时转换削弱更大。不同年龄的儿童在这两种任务转换条件中没有出现显著的年龄差异,说明8~12岁儿童均已具备在两个任务之间进行即时转换的能力。     

内隐的可接近信息对FOK判断等级和准确性的影响

该研究使用RJR研究范式,探讨内隐的可接近信息对FOK判断等级和判断准确性的影响。结果发现：FOK判断等级受内隐的可接近信息量的影响,二者呈非单调递增、递减的关系;FOK判断等级随内隐的可接近信息强度的增强而增高;FOK判断准确性随内隐的可接近信息量的增多而降低,并随内隐的可接近信息强度的增强而增高。     

Constructing robust crew schedules with bicriteria optimization

Optimization‐based computer systems are used by many airlines to solve crew planning problems by constructing minimal cost tours of duty. However, today airlines do not only require cost effective solutions, but are also very interested in robust solutions. A more robust solution is understood to be one where disruptions in the schedule (due to delays) are less likely to be propagated into the future, causing delays of subsequent flights. Current scheduling systems based solely on cost do not automatically provide robust solutions. These considerations lead to a multiobjective framework, as the maximization of robustness will be in conflict with the minimization of cost. For example crew changing aircraft within a duty period is discouraged if inadequate ground time is provided. We develop a bicriteria optimization framework to generate Pareto optimal schedules for the domestic airline. A Pareto optimal schedule is one which does not allow an improvement in cost and robustness at the same time. We developed a method to solve the bicriteria problem, implemented it and tested it with actual airline data. Our results show that considerable gain in robustness can be achieved with a small increase in cost. The additional cost is mainly due to an increase in overnights, which allows for a reduction of the number of aircraft changes. Copyright © 2003 John Wiley & Sons, Ltd.     

心理定势现象的认知神经机制

问题解决活动中的心理定势,是指人们固执地沿用熟悉方案、忽略其他方案的反应倾向。它可能源于人们已经掌握的陈述性知识,也可能源于程序性知识,两类不同来源的心理定势的发生条件和影响效果都不尽相同。然而,过往的研究都没有做出严格区分。本文通过梳理相关研究,描述心理定势现象,解释心理定势是怎么发生的,分析心理定势是在什么条件下发生的、会对心理与行为活动造成什么样的影响,从而评述两种来源的心理定势的认知神经机制,指出尚未解决的科学问题。     

Constructing Cantorian counterexamples

Cantors diagonal argument provides an indirect proof that there is no one-one function from the power set of a set A into A. This paper provides a somewhat more constructive proof of Cantors theorem, showing how, given a function f from the power set of A into A, one can explicitly define a counterexample to the thesis that f is one-one.     

Disbelief,lies, and manipulations in a transactional discourse model

Disbelief, lies, and manipulations have been objects of scholarly consideration from widely different perspectives: historical, sociological, philosophical, ethical, logical, and pragmatic. In this paper, these notions are re-examined in the framework of a Transactional Discourse Model which operates in terms of the location and relocation of various knowledge items within two sets of knowledge, A and B, representing two interlocators A and B, and two of their subsets C_a and C_b, which constitute the sets of the matters of A's and B's current concern. This approach reveals certain formal features shared by lies, disbelief, and manipulations that indicate that these three types of discourse behavior constitute a deviation from successful interpersonal communication as defined in the proposed model. The model, moreover, enables us to explicitly capture both the similarities and the differences of lies and manipulations with other pragmatic phenomena, such as jokes, impersonating, role-acting, memory failure, politeness expressions, and tact; the comparison suggests that certain modifications of Gricean conversational maxims may be in order.
