The Pragmatic Press of Political Reality: Use of P.L. 94-142 Discretionary and Set-Aside Funds

Two major reports regarding the financing of special education and the use of P.L. 94-142 discretionary and set-aside funds are analyzed and interpreted with respect to the impact of these funds on state and local education agencies. The need for flexibility as required by the law, as well as the pragmatic press of political reality in the identification of needs and the distribution of resources, are recognized as key factors in the utilization of these monies. The impact of a change in the amount and/or allocation of these funds are discussed in the context of probable consequences at the state and local levels.

Bets and Boundaries: Assigning Probabilities to Imprecisely Specified Events

Uncertainty and vagueness/imprecision are not the same: one can be certain about events described using vague predicates and about imprecisely specified events, just as one can be uncertain about precisely specified events. Exactly because of this, a question arises about how one ought to assign probabilities to imprecisely specified events in the case when no possible available evidence will eradicate the imprecision (because, say, of the limits of accuracy of a measuring device). Modelling imprecision by rough sets over an approximation space presents an especially tractable case to help get one’s bearings. Two solutions present themselves: the first takes as upper and lower probabilities of the event X the (exact) probabilities assigned X’s upper and lower rough-set approximations; the second, motivated both by formal considerations and by a simple betting argument, is to treat X’s rough-set approximation as a conditional event and assign to it a point-valued (conditional) probability. With rough sets over an approximation space we get a lot of good behaviour. For example, in the first construction mentioned the lower probabilities are n-monotone, for every . When we examine other models of approximation/imprecision/vagueness, and in particular, proximity spaces, we lose a lot of that good behaviour. In the literature there is not (even) agreement on the definition of upper and lower approximations for events (subsets) in the underlying domain. Betting considerations suggest one choice and, again, ways to assign upper and lower and point-valued probabilities, but nothing works well.

The interaction of distress tolerance and intolerance of uncertainty in the prediction of symptom reduction across CBT for social anxiety disorder

Distress tolerance (DT) and intolerance of uncertainty (IU) have been identified as transdiagnostic processes that predict symptom severity across a range of distinct anxiety disorders. However, the joint effect of these two variables on therapeutic outcome has not yet been examined. It is possible that DT and IU may both impact on treatment response to cognitive-behavioural therapy (CBT) in clients with anxiety, as clients with weak DT and strong IU may be less likely to engage in exposure and cognitive restructuring tasks across treatment due to their associated distress. The purpose of this study was to examine the interaction of DT and IU as predictors of post-treatment symptom severity and treatment response to group CBT in participants with primary DSM-IV-TR diagnosed social anxiety disorder (SAD). Participants (N = 95) with SAD completed 12 weeks of manualized group CBT. Results of multilevel longitudinal analysis demonstrated an interaction effect, such that lower DT and higher IU predicted higher SAD symptom severity across the course of therapy. The findings are discussed in terms of clinical implications for the disorder-specific and transdiagnostic treatment of anxiety disorders.     

Commentary on the Current Status of Assessment in Rational-Emotive and Cognitive-Behavior Therapy

This commentary focuses on the current status of assessment in rational-emotive and cognitive-behavior therapy, in the context of making comments about three assessment articles published in the same journal issue. The commentary describes important characteristics of rational-emotive and cognitive-behavior assessment measures, suggests several avenues of psychometric research on behavioral tests of distress tolerance as clinical measures, reviews psychometric and other important properties of existing irrational belief measures, and endorses assessment related to newly proposed anger disorder diagnoses.

Flaw tolerance promoted by dissipative deformation mechanisms between material building blocks

Novel high-performance composite materials often draw inspiration from natural materials such as bone or mollusc shells. A prime feature of such composites is that they are, like their natural counterparts, quasibrittle. They are tolerant to material flaws up to a certain characteristic flaw-tolerant size scale, exhibiting high strength and toughness, but start to behave in a brittle manner when sufficiently large flaws are present. Here, we establish that better flaw tolerance can be achieved by maximizing fracture toughness relative to the maximum elastic energy available in the material, and we demonstrate this concept with simple two-dimensional coarse-grained simulations where the transition from brittle to quasibrittle behaviour is examined.     

风险社会中公众政治信任的形成机制及影响

风险社会中如何提升公众的政治信任成为焦点。以政治信任形成的终生学习理论为基础,将理性选择理论和社会文化理论相整合,探讨影响政治信任形成的因素,以及政治信任对政治合作的影响。对291名被试进行问卷调查,层次回归结果发现：政治信任在政治透明度感知、宽容度感知和政治合作之间发挥正向中介作用;在负面认知固化程度和政治合作之间发挥负向中介作用;政治氛围感知在政治信任和政治合作行为之间起调节作用。最后,对该结果形成的原因与在现实生活中的应用进行讨论,并对未来研究的发展方向进行展望。
