The countable homogeneous universal model of B 2

We give a detailed account of the Algebraically Closed and Existentially Closed members of the second Lee class B ₂ of distributive p-algebras, culminating in an explicit construction of the countable homogeneous universal model of B ₂. The axioms of Schmid [7], [8] for the AC and EC members of B ₂ are reduced to what we prove to be an irredundant set of axioms. The central tools used in this study are the strong duality of Clark and Davey [3] for B ₂ and the method of Clark [2] for constructing AC and EC algebras using a strong duality. Applied to B ₂, this method transfers the entire discussion into an equivalent dual category X ₂ of Boolean spaces which carry a pair of tightly interacting orderings. The doubly ordered spaces of X ₂ prove to be much more readily constructed and analyzed than the corresponding algebras in B ₂.     

顿悟与问题表征的转变

阐述了解决残缺棋盘问题的顿悟过程。该实验的结果证明,顿悟过程中需要发现一种正确的问题表征,即对等性问题空间,为了发现这一表征,被试必须使问题表征从“铺试问题空间”转变为“元水平的问题空间”．被试在这两个空间中进行搜索时,必须有很强的限制,使搜索成为有高度选择性的搜索,才能最终在元水平问题空间中发现正确的表征。本研究还发现,被试的搜索并不总是知觉驱动的,有时是概念驱动的,而且后者的迁移性更高。     

人体系统的非优性与疾病的时空特征

人体系统并非完美,生命抛物线是由生理年龄、社会年龄、人体熵三大要素在非线性作用下相干的结果,从而呈现一种复杂的网状“大Ｘ构架”。每一个交叉点都具有阶段性态变的意义和对生命质量的表征。疾病是人体系统非优的必然。熵压决定了熵的退行性运动,从而也决定了生命时间的有限性。疾病是熵增过程造成机体不同程度封闭的结果。每次疾病都是对熵的增压,造成机体的物质丢失、时间丢失与跳跃,出现熵运动方面的引力偏折,从而在局     

Some effects of response-correlated increases in reinforcer magnitude on human behavior

After training under short or long fixed-interval schedules, humans responded under a modified fixed-interval schedule in which magnitude of reinforcement (X or 2X) was minimally correlated with response frequency. Response frequencies that equaled or exceeded a minimum response criterion were followed by the larger reinforcer at the end of the interval; otherwise, the smaller reinforcer was delivered. The modified schedule alternated with the baseline schedule across conditions. In a control condition, the reinforcer magnitudes produced by control subjects were yoked to those of experimental subjects. Experimental subjects, but not control subjects, showed increased responding. In addition to the baseline and modified fixed-interval schedules used in Experiment 1, subjects in Experiment 2 also responded under a second modified fixed-interval contingency in which increases in reinforcer magnitude were more highly correlated with response frequency. Experimental subjects, but not control subjects, showed increased responding under both procedures. Direct comparison of these two procedures showed that the high-correlation procedure produced greater increases in responding than did the low-correlation procedure.     

Affordances after spinal cord injury

Spinal cord injury can cause cognitive impairments even when no cerebral lesion is appreciable. As patients are forced to explore the environment in a non-canonical position (i.e., seated on a wheelchair), a modified relation with space can explain motor-related cognitive differences compared to non-injured individuals. Peripersonal space is encoded in motor terms, that is, in relation to the representation of action abilities and is strictly related to the affordance of reachability. In turn, affordances, the action possibilities suggested by relevant properties of the environment, are related to the perceiver's peripersonal space and motor abilities. One might suppose that these motor-related cognitive abilities are compromised when an individual loses the ability to move. We shed light on this issue in 10 patients with paraplegia and 20 matched controls. All have been administered an affordances-related reachability judgement task adapted from Costantini, Ambrosini, Tieri, Sinigaglia, and Committeri (2010, Experimental Brain Research, 207, 95) and neuropsychological tests. Our findings demonstrate that patients and controls show the same level of accuracy in estimating the location of their peripersonal space boundaries, but only controls show the typical overestimation of reaching range. Secondly, patients show a higher variability in their judgements than controls. Importantly, this finding is related to the patients’ ability to perform everyday tasks. Finally, patients are not faster in making their judgements on reachability in peripersonal space, while controls are. Our results suggest that not moving freely or as usual in the environment impact decoding of action-related properties even when the upper limbs are not compromised.     

Spaces of the Religious Economy: Negotiating the Regulation of Religious Space in Singapore

Over the past three decades, the theory of religious economy has been established, applied, debated, developed, and rejected. It has proven to be as divisive as any "general theory" of religion should be, and yet its core tenets continue to engage and unite scholars around the world. In response to broader shifts within the sociology of religion, this article reframes religious economy by advancing a spatial approach to its theorization. A spatial approach can help develop new perspectives on the regulation of religion, and the resistant agency of religious groups. With a focus on the "secular monopoly" of Singapore, it demonstrates how the restricted supply of land for religious purposes increases competition between religious groups. To overcome restrictions, religious groups pursue strategies of spatial and organizational boundary crossing. This has led to the closer regulation of space, and highlights the recursive interplay between the regulation and praxis of religion in Singapore.     

Mood and Creativity over Time in a Bipolar Participant

When depression alternates with mania, as in a bipolar affective disorder, creativity might be enhanced. To investigate this, we employed a single‐subject design, looking at both affective space and the spectral covariation of mood and creativity in a participant presenting with bipolar affective disorder. The study was conducted over a period of 54 days, and employed a standard measure of mood (the Brief Mood Introspection Scale) and a standard task of creativity (Alternative Uses Task). Both positive affect and negative affect appear to be somewhat undifferentiated for this participant, and her mood space does not conform to that described by the accepted major dimensions of Arousal and Pleasure. Conceivably, this is because of her rapid mood fluctuations. A 2.7‐day periodicity was found for Tired, Peppy, Nervous, and Calm, on the one hand, and ideational fluency, ideational flexibility, and originality, on the other. In addition, a 9‐day periodicity was common to Happy, Sad, and Gloomy—all three affects clustering in the same affective space—together with both ideational flexibility and originality. This finding brings into question the relationship between creativity and both positive and negative mood.     

可预测性和空格对中文阅读影响的眼动研究

Oneness Experience: Looking Through Multiple Lenses

This article defines healthy oneness experience and establishes the progressive, life enhancing components of the experience. The author clarifies the paradox that a cohesive, well-integrated self allows unitive, non-self-definitional experiences. The author attempts to work the cultural/clinical border by exploring oneness phenomena as they occur in art, religion, literature and the clinical consulting room. The author uses psychoanalytic tools to understand non-clinical experiences of oneness. Through compelling accounts of such experiences as described by artists, writers and meditators, psychoanalytic theorizing about oneness is illumined further.     

Technological Other/Quasi Other: Reflection on Lived Experience

This reflection focuses on lived experience with the Technological Other (Quasi-Other) while pursuing creative video and film activities. In the last decade work in the video and film industries has been transformed through digital manipulation and enhancement brought about by increasingly sophisticated computer technologies. The rules of the craft have not changed but the relationship the artist/editor experiences with these new digital tools has brought about increasingly interesting existential experiences in the creative process. How might this new way of being with technology change the craft and the crafter? Through a phenomenological understanding of Martin Heidegger, Maurice Merleau-Ponty, Don Ihde, and their contributions to the human-technology conversation, this essay moves to reveal the lived experiences of artists/editors who use computers to create by means of film and digital video formats. Exploring notions of lived space, lived body, lived time, and lived relation through the computer interface allows for digging deeper into inhabiting technology and experiencing the Technological Other.
