工作不安全感对员工心理与行为的影响

采用工作不安全感问卷,对不同企业的223名员工进行调查,探讨了工作不安全感中各维度对员工心理与行为的具体影响。结果表明:(1)在工作执行和人际关系不安全感上,男女性别差异显著;在工作丧失、人际关系不安全感、群体组织公民行为以及留职意愿这四个维度上,不同企业类型差异显著。(2)工作丧失、工作执行,人际关系不安全感均对留职意愿有正向预测作用;过度竞争不安全感对群体组织公民行为及个体组织公民行为均有显著的负向预测作用。     

The auditory motion aftereffect: its tuning and specificity in the spatial and frequency domains

In this paper, the auditory motion aftereffect (aMAE) was studied, using real moving sound as both the adapting and the test stimulus. The sound was generated by a loudspeaker mounted on a robot arm that was able to move quietly in three-dimensional space. A total of 7 subjects with normal hearing were tested in three experiments. The results from Experiment 1 showed a robust and reliable negative aMAE in all the subjects. After listening to a sound source moving repeatedly to the right, a stationary sound source was perceived to move to the left. The magnitude of the aMAE tended to increase with adapting velocity up to the highest velocity tested (20 degrees/sec). The aftereffect was largest when the adapting and the test stimuli had similar spatial location and frequency content. Offsetting the locations of the adapting and the test stimuli by 20 degrees reduced the size of the effect by about 50%. A similar decline occurred when the frequency of the adapting and the test stimuli differed by one octave. Our results suggest that the human auditory system possesses specialized mechanisms for detecting auditory motion in the spatial domain.     

A cGMP-dependent protein kinase gene, foraging, modifies habituation-like response decrement of the giant fiber escape circuit in Drosophila

The Drosophila giant fiber jump-and-flight escape response is a model for genetic analysis of both the physiology and the plasticity of a sensorimotor behavioral pathway. We previously established the electrically induced giant fiber response in intact tethered flies as a model for habituation, a form of nonassociative learning. Here, we show that the rate of stimulus-dependent response decrement of this neural pathway in a habituation protocol is correlated with PKG (cGMP-Dependent Protein Kinase) activity and foraging behavior. We assayed response decrement for natural and mutant rover and sitter alleles of the foraging (for) gene that encodes a Drosophila PKG. Rover larvae and adults, which have higher PKG activities, travel significantly farther while foraging than sitters with lower PKG activities. Response decrement was most rapid in genotypes previously shown to have low PKG activities and sitter-like foraging behavior. We also found differences in spontaneous recovery (the reversal of response decrement during a rest from stimulation) and a dishabituation-like phenomenon (the reversal of response decrement evoked by a novel stimulus). This electrophysiological study in an intact animal preparation provides one of the first direct demonstrations that PKG can affect plasticity in a simple learning paradigm. It increases our understanding of the complex interplay of factors that can modulate the sensitivity of the giant fiber escape response, and it defines a new adult-stage phenotype of the foraging locus. Finally, these results show that behaviorally relevant neural plasticity in an identified circuit can be influenced by a single-locus genetic polymorphism existing in a natural population of Drosophila.     

欧阳渐"佛法非宗教非哲学"思想衍论

“佛法非宗教非哲学”的思想是近代佛学大师欧阳渐先生提出来的。该文考察了欧阳渐对“佛法”的理解,并在对“如何正确理解”、“如何客观评判”、“如何合理发扬”欧阳渐“佛法”思想等问题展开讨论的同时,简要分析了该思想的成因、价值及其学术意义。该文认为：要客观评判欧阳渐的“佛法”思想,应该正确区分“佛法”与“佛教”、“佛学”的关系,全面理解其“佛法”思想,并根据“佛法”的实际来加以评价;佛法非宗教非哲学而始终为人类所必需,乃是欧阳渐“佛法”思想留给我们的有益启示,值得在深入思考和研究的基础上加以发扬。     

Cross-cultural equivalence and validity of the Vietnamese MMPI-2: assessing psychological adjustment of Vietnamese refugees

The cross-cultural equivalence and validity of the Vietnamese translation of the Minnesota Multiphasic Personality Inventory--2 (MMPI-2) were examined in a sample of 1st-generation Vietnamese refugees in the United States (N = 143). Respondents completed the Vietnamese MMPI-2, the Harvard Trauma Questionnaire, a measure of acculturation, and a demographic questionnaire. An inspection of MMPI-2 mean profiles and items showing extreme endorsement rates suggested that certain symptom tendencies and cultural values may be reflected in responses to some MMPI-2 items. Older age, lower acculturation, greater experienced premigration-postmigration traumas, and military veteran status were all associated with elevated MMPI-2 profiles, suggesting that the MMPI-2 functions in a reasonably equivalent and valid way in this population.

The effect of the physical versus mental presence of a high-powered person on consumers' healthy food choices

Consumers make distinct food choices when they see versus when they think about a powerful person. This research identifies two scenarios involving the presence of a high-powered other, physical presence versus mental presence, and examines the effect of the physical and mental presence of a high-powered other on consumers' healthy food choices. Conducting six experiments, we show that the physical presence of a high-powered other increases one's self-enhancement motivation and leads to healthier food choices, while the mental presence of a high-powered other increases one's perceived constraints and leads to unhealthy food choices. We also find that interpersonal closeness moderates the positive effect of the physical presence of a high-powered other on healthy food choices but does not moderate the negative effect of the mental presence of a high-powered other on healthy food choices.     

弘扬孟子仁政思想精华促进建设和谐小康社会

孟子继承发挥孔子仁学德治思想,提出以民为本的仁政学说,经剔除其封建糟粕,具超时代超阶级的积极意义.孟子仁政说中保民而王、亲亲仁民、与民同乐及制民之产以安民富民的思想,其积极意义、历史贡献须充分肯定,它对我们今天加强党风政风建设,促进加强社会主义政治文明精神文明建设,促进全面建设和谐小康社会,有现实意义,须大力弘扬.     

概念及概念结构研究新进展

近来有关归类和概念结构的研究与理论出现了两个方面的转变。第一个方面是从概念定义属性的假设 (经典观 )到概念表征属性的观点 (概率观 ) ;第二个方面是从概念以相似性组织的观点到概念围绕理论而组织的观点。本文综合概述了基于相似性和理论驱动的归类理论。
