The Professor and the Saint

I review James E. Dittes' scholarship on St. Augustine through the perspective of my experiences as a student in his seminar on The `Theologies' of Freud and Jung, sponsored by the National Endowment for the Humanities. Throughout this review, I emphasize Dittes' personal engagement with Augustine, and note his unabashed introspection as a mode of theological reflection.     

初中生羞怯与手机依赖的关系:一个有调节的中介模型

为探讨初中生羞怯、疏离感、班级心理环境和手机依赖的关系,采用羞怯量表、青少年疏离感量表、班级心理环境量表和手机依赖指数量表对山东省两所学校的1077名初一至初三年级的学生进行调查。结果显示：（1）羞怯显著正向预测初中生手机依赖;（2）疏离感在初中生羞怯与手机依赖之间起完全中介作用;（3）班级心理环境对中介效应的后半段路径起调节作用,高班级心理环境会缓解疏离感对手机依赖的影响,但在极高疏离感水平下,高班级心理环境反而会加剧个体的手机依赖水平。研究有助于了解羞怯对手机依赖的复杂影响机制,对预防以及减少初中生手机依赖具有一定的现实意义。     

A behavioral economic analysis of concurrently available money and cigarettes.

In economic terms, consumption of a reinforcer is determined by its price and the availability and price of other reinforcers. This study examined the effects of response-requirement (i.e., price) manipulations on the self-administration of two concurrently available reinforcers. Six cigarette smokers participated in 4-hr sessions in which money and puffs on a cigarette were concurrently available according to fixed-ratio schedules of reinforcement. Once stable responding was obtained with both reinforcers available at Fixed Ratio 100, the response requirement for one reinforcer was systematically varied (Fixed Ratio 1,000 and 2,500), while the other reinforcer remained scheduled at Fixed Ratio 100. Increasing the fixed-ratio size for a reinforcer decreased its consumption, with a greater decrease occurring for monetary reinforcement. This finding was quantified in economic terms as own-price elasticity, with elasticity coefficients greater for money than cigarettes. The effects of fixed-ratio size on response output also differed across the two reinforcers. Although greater responding occurred for money at Fixed Ratio 100, increases in fixed-ratio size (for money) decreased responding for money, whereas the same increase in fixed-ratio size (for puffs) increased responding for puffs. Finally, increasing the fixed-ratio size for one reinforcer had little effect on consumption of the other concurrently available reinforcer. This finding was quantified as cross-price elasticity, with elasticity coefficients near 0.0 for most subjects, indicating little or no reinforcer interaction. The results indicate that the reinforcing effects of cigarettes and money in the setting studied here differed, and that the effects produced by changing the price of one reinforcer did not interact with the consumption of the other concurrently available reinforcer.     

心理戒毒实验研究

1问题以往对毒品依赖者的临床治疗,偏重于躯体依赖的药物戒治,实践表明,克服戒断反应并不困难。然而,戒断反应消除了,毒瘾却并没戒除,表现是：复吸率非常高──达98％。如此之高的复吸率引起我们的注意：反复吸毒到底是一个生理问题还是一个心理问题？吸毒者在反复吸毒过程中追求的是什么？由此,导向另一个更深层次的问题：“戒毒要戒掉什么？”我们就此问题进行了调查,调查对象包括广州、探圳等戒毒所收治的150名吸毒者。结果显示：（1）开始吸毒时有非常强烈的情绪体验,这种情绪体验的强烈程度和愉快程度远远超过性交的体验。随…     

Drug effects on fixed-interval responding with pause requirements for food presentation.

In pigeons performing under a multiple schedule of food presentation, low key-pecking rates (0.18 to 0.29 responses per second) were maintained during 3-min fixed-interval components by requiring a 4-, 5-, or 6-sec pause preceding the food-delivery response (tandem DRL), while higher rates (0.70 to 1.37 responses per second) were maintained in alternative fixed-interval components by requiring a pause of no more than 40 msec preceding the food-delivery response (tandem DRH). Thus, reinforcement density was equal but overall response rates markedly different in the two schedule components. Pentobarbital (3, 10 mg/kg) had effects on overall rates of responding consistent with a rate-dependency interpretation (low rates were increased while higher rates were decreased), but d-amphetamine (0.03 to 3 mg/kg) either failed to increase low overall rates in the tandem DRL components or increased them only slightly. Effects of both drugs on local responding within the fixed-intervals were always related in an orderly way to control response rate, but the extent of rate increases produced by d-amphetamine was modifed in some birds by pause requirements such that the drug increased comparable rates less when these occurred in the tandem DRL component than when they occurred in the tandem DRH components. Control rate is an important determinant of drug effects, independent DRH components. Control rate is an important determinant of drug effects, independent of reinforcement density maintaining rates, and independent of environmental influences, such as response-spacing requirements for food presentation, that can modify the extent of some drug-produced rate changes.     

The effects of aerobic exercise on working memory in methamphetamine-dependent patients: Evidence from combined fNIRS and ERP

ObjectiveTo explore the effect of aerobic exercise on working memory according to exercise intensity in patients with methamphetamine (MA) dependence.DesignTwelve-week randomized controlled trial.MethodForty-five MA-dependent patients were divided randomly into three groups participating in 12-week moderate- and high-intensity aerobic exercise interventions and no intervention (control), respectively. Working memory performance was assessed using a 2-back task, and a combined functional near-infrared spectral imaging–event-related potential measure was used to identify spatial and temporal components of the neurofunctional underpinnings of this performance.ResultsHigh-intensity exercise significantly enhanced the discernment aspect of working memory. It also decreased N1 and P2 amplitudes, and increased neural activity in the left dorsolateral prefrontal cortex.ConclusionsThe findings of this study suggest that high-intensity aerobic exercise can enhance working memory and neural activity in MA-dependent patients, and thus that it may serve as an effective therapeutic tool for these patients.     

行为公共管理学视角下公共决策的社会许可机制：“一提两抑”

公共管理的本质是公共决策。“公共决策的社会许可”指当地民众对于公共决策的持续接受和支持程度, 是公共决策合法性的基石。本研究借助“行为公共管理学”的理论视角, 通过两个调查实验(N = 354 + 354), 一个现场调查(N = 520), 全面考察公共决策透明(过程透明和内容透明)与社会许可之间的因果关系, 进而明确这一关系的作用边界。结果发现：1) 决策过程透明与内容透明正向影响社会许可; 2) 政府信任调节决策内容透明与社会许可的关系; 3) 结果依赖调节两类透明与社会许可的关系。基于这些结果, 作者总结出正性的“决策透明效应”以及“谨慎的不介意”和“有选择的忽视”之双缓冲作用, 即“一提两抑”, 以更好地理解公共决策的社会许可机制。     

From IF to BI

We take a fresh look at the logics of informational dependence and independence of Hintikka and Sandu and Väänänen, and their compositional semantics due to Hodges. We show how Hodges’ semantics can be seen as a special case of a general construction, which provides a context for a useful completeness theorem with respect to a wider class of models. We shed some new light on each aspect of the logic. We show that the natural propositional logic carried by the semantics is the logic of Bunched Implications due to Pym and O’Hearn, which combines intuitionistic and multiplicative connectives. This introduces several new connectives not previously considered in logics of informational dependence, but which we show play a very natural rôle, most notably intuitionistic implication. As regards the quantifiers, we show that their interpretation in the Hodges semantics is forced, in that they are the image under the general construction of the usual Tarski semantics; this implies that they are adjoints to substitution, and hence uniquely determined. As for the dependence predicate, we show that this is definable from a simpler predicate, of constancy or dependence on nothing. This makes essential use of the intuitionistic implication. The Armstrong axioms for functional dependence are then recovered as a standard set of axioms for intuitionistic implication. We also prove a full abstraction result in the style of Hodges, in which the intuitionistic implication plays a very natural rôle.
