Contributions of the dorsal hippocampus and the dorsal subiculum to processing of idiothetic information and spatial memory

It is well established that the dorsal hippocampal formation is crucial for spatial memory in rats. However, little is known about the distinct functions of the dorsal hippocampus and the dorsal subiculum. To examine the role of the dorsal hippocampus and the dorsal subiculum, Long-Evans rats with excitotoxic lesions (NMDA) of the dorsal hippocampus (DH), the dorsal subiculum (DS), or both (DHDS), and controls were trained on a nonmatching-to-place task. Then, to identify the strategy used by each group, they were tested on the same task in the dark with the T-maze being rotated between the sample and the test runs. In the light, rats with combined lesions were impaired. In the dark, groups DH, DS, and controls performed near chance level except in trials without rotation, suggesting the use of a sense of direction. The same rats were trained on a radial-arm maze task. In the light, where proximal visual cues were accessible, combined lesions affected performance whereas in the dark, it was impaired by all lesions. This experiment demonstrated that the dorsal subiculum and the dorsal hippocampus play a crucial role in processing idiothetic information and/or in maintenance of this information in memory.     

A preliminary investigation of acceptance and commitment therapy as a treatment for marijuana dependence in adults

In this investigation, 3 adults who met criteria for marijuana dependence were treated using an abbreviated version of acceptance and commitment therapy (ACT). The treatment was delivered in eight weekly 90-min individual sessions. The effects of the intervention were assessed using a nonconcurrent multiple baseline across participants design. Self-reported marijuana use, confirmed through oral swabs, reached zero levels for all participants at posttreatment. At a 3-month follow-up, 1 participant was still abstinent and the other 2 were using but at a lower average level of consumption compared to baseline. Depression, anxiety, withdrawal symptoms, and general levels of experiential avoidance generally improved. This preliminary test suggests that additional development and testing of ACT for marijuana use are warranted.     

预见性的本体论指归

囿于认识论或价值论范围,把有关预见性的一切解释置于本体论解释的视野之外,预见性的本体论根据之追究就会被无端地“搁置”起来,从而处在被“荒漠化”的境地,本体论意义之显现也就会被严实地“遮蔽”起来,即使偶有论及也只处在被“边缘化”的地带。本文由自我认识的诠解引发关于自我认识的预见性研究的本体论和方法论意义,进而集中解说自我认识何以具有预见性,自我认识的预见性有什么特点和表现形式,其存在变化是否具有客观基础暨本体论指归。     

Abrupt onsets and gaze direction cues trigger independent reflexive attentional effects

The present study investigated whether the direction of visual signals is influenced independently by two automatic visual orienting phenomena: orienting to a gazed-at location and inhibition of return (IOR) to the location of an abrupt onset. A schematic face served as both a nonpredictive gaze direction cue and an abrupt onset cue. Results indicated that target detection was facilitated at the gazed-at location, and that it was inhibited at the abrupt onset location. Importantly, these two different reflexive attention effects were triggered by the same event and exhibited overlapping time courses. Moreover, the IOR effect did not vary as a function of the facilitatory effect of gaze. These findings strongly suggest that reflexive attention to gaze direction and reflexive inhibition to an abrupt onset are independent processes, and that gaze direction does not produce IOR at the gazed-at location.     

On the need for negative local item dependence

While negative local item dependence (LID) has been discussed in numerous articles, its occurrence and effects often go unrecognized. This is due in part to confusion over what unidimensional latent trait is being utilized in evaluating the LID of multidimensional testing data. This article addresses this confusion by using an appropriately chosen latent variable to condition on. It then provides a proof that negative LID must occur when unidimensional ability estimates (such as number right score) are obtained from data which follow a very general class of multidimensional item response theory models. The importance of specifying what unidimensional latent trait is used, and its effect on the sign of the LIDs are shown to have implications in regard to a variety of foundational theoretical arguments, to the simulation of LID data sets, and to the use of testlet scoring for removing LID.This paper is based in part on a chapter in the first author's doctoral dissertation, written at the University of Illinois at Urbana-Champaign under the supervision of William Stout. Part of this research has been presented at the annual meeting of the National Council on Measurement in Education, San Diego, California, April 14–16, 1998.The research of the first author was partially supported by a Harold Gulliksen Psychometric fellowship through Educational Testing Service and by a Research and Productive Scholarship award from the University of South Carolina.     

始终代表中国先进文化的前进方向

“三个代表”是个有机的整体。始终代表中国先进文化的前进方向,是其中的关键环节。中国共产党从来就是与先进文化紧密联系在一起的。党的十六大把“三个代表”列入党章,有着重大的理论意义。     

The Moral Contours of Empathy

Morally contoured empathy is a form of reasonable partiality essential to the healthy care of dependents. It is critical as an epistemic aid in determining proper moral responsiveness; it is also, within certain richly normative roles and relationships, itself a crucial constitutive mode of moral connection. Yet the achievement of empathy is no easy feat. Patterns of incuriosity imperil connection, impeding empathic engagement; inappropriate empathic engagement, on the other hand, can result in self-effacement. Impartial moral principles and constraints offer at best meager protection against these perils, and hence serve poorly in securing morally contoured empathy. More nuanced and practical guidance should be sought in normatively substantive conceptions of our roles and relationships and their defining moral stakes. These, joined with more abstract moral tools, can facilitate rich, narratively textured interpretations of moralitys demands. While the content of our normative conceptions must be continually debated, engaging in this debate is vital to the achievement of proper empathy, and thus to effective, respectful, morally healthy care of dependents.This paper was originally presented at the conference on Reasonable Partiality at the Vrije Universiteit, Amsterdam, October 22–24, 2003. I wish to thank all those present for stimulating discussion. Special thanks go to Bert Musschenga, who organized the conference, and who has provided insightful feedback on this paper. Warm thanks as well to Brenda Almond and Bernie Rollin for lively exchanges on the issues addressed here and to Nancy Sherman for sharing with me an ongoing fascination with, and her own fantastic work on, empathy. Comments from an anonymous reviewer for the journal were challenging and helpful. Finally, I wish to express gratitude beyond normal bounds to Maggie Little both for her generosity, keen insight, and artful intervention at key points in this essays evolution and for her ground-breaking work on deontic pluralism that deeply influences the position I frame here.     

The Rôle of Language In Belief Revision

Analytical tools that give precision to the concept of "independence of syntax" are developed in the form of a series of substitutivity principles. These principles are applied in a study of the rôle of language in belief revision theory. It is shown that sets of sentences can be used in models of belief revision to convey more information than what is conveyed by the combined propositional contents of the respective sets. It is argued that it would be unwise to programmatically restrain the use of sets of sentences to that of representing propositional contents. Instead, the expressive power of language should be used as fully as possible. Therefore, syntax-independence should not be seen as a criterion of adequacy for language-based models of information-processing, but rather as a property that emerges from some but not all the idealization processes through which such models are constructed.     

The adoption of innovation in collective action organizations

This study used a quantitative/qualitative methodology to explore how collective action organizations (CAOs) remain open to organizational change and innovation. It examined the adoption of inclusion—a recent innovation in the field of disabilities—by local chapters of The Arc Michigan (a disabilities CAO). We found considerable variability in the adoption of inclusion by local Arc chapters. This variability was significantly related to the ecology surrounding these chapters. Local Arc chapters that had adopted an inclusion philosophy had significantly different internal and external environments from those that had not adopted inclusion. Our qualitative findings make it clear, however, that innovative Arc chapters were not the passive recipients of these internal and external influences. These chapters were proactive players in defining and shaping the nature of their internal and external environments. Strategies that were related to a chapter's ability to remain open to innovation included (a) a change orientation, (b) a conscious philosophy or vision, (c) a proactive strategy for achieving chapter goals and overcoming barriers to change, (d) the creation of a supportive organizational network, and (e) avoidance of resource dependencies that required them to engage in activities that were inconsistent with the innovation. These findings provide a framework by which CAOs can maintain an openness to innovation and remain on the forefront of social change.
