自由与功利之间——密尔伦理思想的双重诉求

约翰·斯图亚特·密尔是一个功利主义者,更是一个自由主义者.功利原则与自由原则是密尔伦理思想中的两个密切相关的基本原则,功利原则以最大多数人的最大幸福为终极价值诉求,自由原则则赋予个体的自由权利以价值优先性.密尔的一生都致力于以功利原则为哲学基础来证明个体自由,致力于论证功利主义与自由主义的一致与契合,但实际上若要追求功利原则和自由原则的融合就决定了他既不能执守严格的功利主义,也无法坚持一般的自由主义.因此,功利主义不是自由主义最好的哲学基础.     

社会主义核心价值观初探

确立社会主义核心价值观,是建设社会主义核心价值体系的重要内容.以富强、民主、文明、和谐和人的自由全面发展为内容的社会主义核心价值观,体现着社会主义的价值本质,是社会主义核心价值体系的内核,是社会主义建设的灵魂,指导着社会主义的奋斗目标和前进方向,引领着中国特色社会主义的伟大实践.     

公正与关怀——民生制度与实践的伦理原则

从伦理学的视角来看,民生包含三个方面的内涵:一是公民根基性的"生存",二是公民尊严性的"生活",三是公民理想性的"好的生活".基于对中国当下民生的现状及问题的全面把握,政府在民生制度和民生实践中首先应遵循刚性的公正原则,它既能够一般地解决资源供给的有限与人的欲望的无限之间的冲突,又能有效地解决当下民生中的突出问题.但公正原则的普遍性和抽象性决定了它无法惠及每一特殊个体的需求,强调具体性、关系性、情境性、理解与关爱的关怀原则可以弥补这一缺陷.因此,以刚性的"公正"与柔性的"关怀"为伦理原则的民生制度与民生实践,将最终引领全体公民过上他们所珍视的和值得过的"好的生活".     

宽恕干预对降低农村留守儿童拒绝敏感性的作用

为探讨宽恕干预对降低农村留守儿童拒绝敏感性的作用,本研究将18名高拒绝敏感性农村留守儿童随机分配到实验组和控制组,其中实验组接受为期六周的团体宽恕干预,控制组不接受任何干预。结果显示:(1)留守儿童的拒绝敏感性水平与宽恕水平之间存在显著负相关。(2)在前测数据中,实验组和控制组之间不存在显著差异;在后测和追踪数据中,实验组儿童的拒绝敏感性水平显著低于控制组。(3)在干预之后,实验组留守儿童的拒绝敏感性水平显著下降,并且维持在较低水平,而控制组留守儿童的拒绝敏感性水平始终处于较高水平。该结果在一定程度上证明宽恕干预对降低农村留守儿童的拒绝敏感性水平是有效的,并且其效果稳定。     

义务教育阶段学业质量监测题库建设的理论与实践

义务教育阶段学业质量监测是学生学业质量评价的重要方式,在当前国内外教育质量评价领域中发挥着极为重要的作用.加强学业质量监测的题库建设,则是促进学业质量监测工具的命制与实施从经验型向科学化迈进的必由之路.本文在对义务教育阶段学业质量监测题库的性质和功能进行阐述的基础上,重点探讨了学业质量监测题库建设的理论基础、基本流程和关键环节,并进一步分析指出了当前题库建设中有待深入研究的问题.     

面孔—人格知觉的影响因素

人们会迅速地对目标人物的面孔线索进行人格特质分析,进而形成对目标的人格第一印象。在这个面孔—人格知觉的过程中,知觉结果会受到知觉对象、知觉者以及两者交互作用的影响。本文基于这三个方面对影响面孔—人格知觉的因素进行了综述和展望,以期更系统、科学地研究与看待面孔—人格知觉,并为人际印象设计与管理等提供理论参考。     

Phobic anxiety in 11 nations. Part I: Dimensional constancy of the five-factor model

The Fear Survey Schedule-III (FSS-III) was administered to a total of 5491 students in Australia, East Germany, Great Britain, Greece, Guatemala, Hungary, Italy, Japan, Spain, Sweden, and Venezuela, and submitted to the multiple group method of confirmatory analysis (MGM) in order to determine the cross-national dimensional constancy of the five-factor model of self-assessed fears originally established in Dutch, British, and Canadian samples. The model comprises fears of bodily injury-illness-death, agoraphobic fears, social fears, fears of sexual and aggressive scenes, and harmless animals fears. Close correspondence between the factors was demonstrated across national samples. In each country, the corresponding scales were internally consistent, were intercorrelated at magnitudes comparable to those yielded in the original samples, and yielded (in 93% of the total number of 55 comparisons) sex differences in line with the usual finding (higher scores for females). In each country, the relatively largest sex differences were obtained on harmless animals fears. The organization of self-assessed fears is sufficiently similar across nations to warrant the use of the same weight matrix (scoring key) for the FSS-III in the different countries and to make cross-national comparisons feasible. This opens the way to further studies that attempt to predict (on an a priori basis) cross-national variations in fear levels with dimensions of national cultures.     

Neural correlates of Pavlovian conditioning in components of the neural network supporting ciliary locomotion in Hermissenda

Pavlovian conditioning in Hermissenda consists of pairing light, the conditioned stimulus (CS) with activation of statocyst hair cells, the unconditioned stimulus (US). Conditioning produces CS-elicited foot shortening and inhibition of light-elicited locomotion, the two conditioned responses (CRs). Conditioning correlates have been identified in the primary sensory neurons (photoreceptors) of the CS pathway, interneurons that receive monosynaptic input from identified photoreceptors, and putative pedal motor neurons. While cellular mechanisms of acquisition produced by the synaptic interaction between the CS and US pathways are well-documented, little is known about the mechanisms responsible for the generation or expression of the CR. Here we show that in conditioned animals light reduced tonic firing of ciliary activating pedal neurons (VP1) below their pre-CS baseline levels. In contrast, pseudorandom controls expressed a significant increase in CS-elicited tonic firing of VP1 as compared to pre-CS baseline activity. Identified interneurons in the visual pathway that have established polysynaptic connections with VP1 were examined in conditioned animals and pseudorandom controls. Depolarization of identified type I_e interneurons with extrinsic current elicited a significant increase in IPSPs recorded in VP1 pedal neurons of conditioned animals as compared with pseudorandom controls. Conditioning also enhanced intrinsic excitability of type I_e interneurons of conditioned animals as compared to pseudorandom controls. Light evoked a modest increase in IPSP frequency in VP1 of conditioned preparations and a significant decrease in IPSP frequency in VP1 of pseudorandom controls. Our results show that a combination of synaptic facilitation and intrinsic enhanced excitability in identified components of the CS pathway may explain light-elicited inhibition of locomotion in conditioned animals.
