国有企业经营者道德风险:深层导因及对策研究

我国国有企业经营者出现道德风险行为的原因主要来自这样几个方面:国有企业产权制度本身的缺陷、法人治理结构的缺陷、国有企业经营者人力资本与其报酬的不对称、对国有企业经营者难以进行有效的监督。要消除国有企业经营者道德风险行为,需要从建立健全企业经营者的激励机制、建立健全公司内部的权利制衡机制、建立严格的约束机制、完善公司治理结构、加强监督等方面采取防范对策。     

伴有广场恐怖症的惊恐障碍的网络心理学治疗新技术

近年来,加拿大Universitédu Québec en Outaouais大学Bouchard教授领导的团队进行了一系列网络心理学的研究,这种研究尝试将最新的计算机技术融合到传统临床心理治疗中去,并通过实验来评估其疗效。针对伴有广场恐怖症的惊恐障碍的研究一直是其研究重点,其包括对传统认知行为疗法(Cognitive Behavior Therapy,CBT)的评价研究、将远程视频会议技术应用于CBT疗法的研究,以及将虚拟现实技术与传统CBT疗法相结合的研究。     

颜色对基于时间的视觉选择的影响

旨在探讨颜色属性对基于时间的图形预览搜索的影响及其机制。实验采用视觉标记实验范式的变式考察三种颜色的图形刺激的预览收益。结果发现:搜索与旧干扰物相同颜色的靶子和搜索新异颜色刺激并未出现反应时的差异,而且,两者都快于搜索与新干扰物颜色相同的靶子。这说明,在图形刺激的预览搜索中,观察者没有主动抑制旧干扰物的颜色,而是主动加工新出现的刺激。还探讨了基于颜色标记的抑制机制和主动非抑制机制。

多级计分测验中基于残差统计量的被试拟合研究

本文提出一种多级计分项目下的个人拟合统计量R, 考察它在检测6种常见的异常作答模式(作弊、猜测、随机、粗心、创新作答、混合异常)下的表现, 并与标准化对数似然统计量l_zp进行比较。结果表明：(1) 在异常作答覆盖率较低并且异常作答类型为作弊和猜测时, R的检测率显著高于l_zp; (2) 随着测验长度和被试异常程度的增加, 两种统计量的检测率都会上升; (3) 在一些条件下, R与l_zp检测效果接近。实证数据分析进一步展示了R统计量的使用方法和过程, 结果也表明R统计量具有较好的应用前景。     

心理信息学:网络信息时代下的心理学新发展

在见证了社会计算与计算社会科学的勃兴之后,心理学和信息科学在网络信息时代相遇,催生出心理信息学这门新兴交叉学科。该学科旨在利用计算机与信息科学技术,通过开展网络调查和实验、开发和利用移动设备、建立数据库和分类体系、使用开源软件和数据挖掘技术等,获取、整理和分析心理学研究资料。其对大规模复杂数据的掌控能力,使心理学家可以从新的高度和视野,针对现实和虚拟网络中的个体与群体心理现象展开研究,重新检视已有理论假设并探索新发现。但是,心理信息学在展现巨大潜力的同时,也在技术和研究设计、伦理和研究规范、研究重心与人才培养等诸多方面面临挑战。     

Solving Smullyan Puzzles with Formal Systems

Solving numeric, logic and language puzzles and paradoxes is common within a wide community of high school and university students, fact witnessed by the increasing number of books published by mathematicians such as Martin Gardner (popular books as old as Gardner in Aha! insight. W. H. Freeman & Co., London, 1978, Wheels, life and other mathematical amusements. W H Freeman & Co., London, 1985), Douglas Hofstadter [in one of the best popular science books on paradoxes (Hofstadter in Godel, escher, bach: an eternal golden braid, Penguin, London, 2000)], inspired by Gödel’s incompleteness theorems), Patrick Hughes and George Brecht (see Hughes and Brecht in Vicious circles and infinity, an anthology of paradoxes. Penguin Books, London, 1993) and Raymond M. Smullyan (the most well known being Smullyan in Forever undecided, puzzle guide to godel. Oxford Paperbacks, Oxford 1988, To Mock a Mockingbird and other logic puzzles. Oxford Paperbacks, Oxford 2000, The lady or the tiger? And other logic puzzles. Dover Publications Inc., Mineola 2009), inter alia. Books by Smullyan (such as Smullyan 1988, 2000) are, however, much more involved, since they introduce learning trajectories and strategies across several subjects of mathematical logic, as difficult as combinatorial logic (see, e.g., Smullyan 2000), computability theory (see Smullyan 1988), and proof theory (see Smullyan 1988, 2009). These books provide solutions to their suggested exercises. Both statements and their solutions are written in the natural language, introducing some informal algorithms. As an exercise in Mathematics we wonder if an easy proof system could be devised to solve the amusing equations proposed by Smullyan in his books. Moreover, university students of logic could well train themselves in constructing deductive systems to solve puzzles instead of a non-uniform treatment one by one. In this paper, addressing students, we introduce one such formal systems, a tableaux approach able to provide the solutions to the puzzles involving either propositional logic, first order logic, or aspect logic. Let the reader amuse herself or himself!     

孙诒让管子研究之特色与影响

道咸以来,考据学渐衰,《管子》研究也随之进入了平缓时期。生活于清末的学者孙诒让,在《管子》研究史上承前启后,乃清末考据学之杰出者。他的《札迻》引经据典,校勘辨疑,极有乾嘉之遗风。特别是其中的《管子》部分,充分体现其学术思想,无论内容还是特色,很有典型性。后世学者校读《管子》,多以不同版本对勘,再参以前人之成果,注重多重证据,就是受了孙诒让《管子》研究的影响。     

Gender differences in children's arithmetic performance are accounted for by gender differences in language abilities

Studies have shown that female children, on average, consistently outperform male children in arithmetic. In the research reported here, 1,556 pupils (8 to 11 years of age) from urban and rural regions in the greater Beijing area completed 10 cognitive tasks. Results showed that girls outperformed boys in arithmetic tasks (i.e., simple subtraction, complex multiplication), as well as in numerosity-comparison, number-comparison, number-series-completion, choice reaction time, and word-rhyming tasks. Boys outperformed girls in a mental rotation task. Controlling for scores on the word-rhyming task eliminated gender differences in arithmetic, whereas controlling for scores on numerical-processing tasks (number comparison, numerosity estimation, numerosity comparison, and number-series completion) and general cognitive tasks (choice reaction time, Raven's Progressive Matrices, and mental rotation) did not. These results suggest that girls' advantage in arithmetic is likely due to their advantage in language processing.
