陌生的邻居:东正教之于中俄相互认知上的障碍性角色

在中俄战略协作伙伴关系的框架下,双方的确没有出现如中美或中国与欧盟之间那样的纷争和冲突,但也缺乏中美、中欧之间相互深刻影响对方的社会进程、经济发展和生活方式变革等积极成果。造成这种矛盾现象的因素固然复杂,但俄罗斯东正教作为远远超出宗教领域的巨大存在,影响着后苏联社会进程的每个方面,却不能被中俄战略协作伙伴关系所考虑,这在客观上必然影响俄中关系,应该是这种战略实施后果不很理想的重要原因。本文探讨两个问题:俄罗斯东正教之于后苏联的超常重要性,以及,中国对俄国的认知绕开东正教因素和无神论政策是不可能的。     

班级辅导对改善初中生乐观心理品质的实验研究

以《生活取向测量修订版》、《儿童解释风格问卷》、《中国中学生心理健康量表》为评估工具,从积极心理学和积极心理健康教育的理念出发,对实验班进行8周的班级辅导。结果表明:班级心理辅导能改善和培养初中生乐观心理品质。     

维生素D在危重病治疗中的价值

近年来随着研究的深入,发现维生素D除了调节钙磷代谢外,对先天性免疫、适应性免疫亦具有调节作用,其不仅能降低重症加强治疗病房(ICU)内多器官衰竭的病死率,还能预测疾病的严重程度及预后,在危重患者中具有广阔的应用前景,可作为ICU的一种辅助治疗手段.

Association of catechol-O-methyltransferase (COMT) polymorphism and academic achievement in a Chinese cohort

Catechol-O-methyltransferase (COMT) is a methylation enzyme that catalyzes the degradation pathway and inactivation of dopamine. It is accepted widely as being involved in the modulation of dopaminergic physiology and prefrontal cortex (PFC) function. The COMT Val158Met polymorphism is associated with variation in COMT activity. COMT 158Met allele may be advantageous for PFC-related cognitive abilities; however, it is also associated with increased anxiety, depression, and emotional vulnerability in response to stress or educational adversity. We hypothesized that the COMT polymorphism might be associated with academic performance. In this study, 779 Taiwanese tenth-grade volunteers were recruited. Scores from the Basic Competency Test (BCT), an annual national competitive entrance examination, were used to evaluate academic performance. The results indicated that students bearing homozygous for the Met allele tended to perform more poorly in all BCT subtests as compared to the other groups. In particular, the former performed significantly more poorly in the science and social science subtests. These findings provide evidence that affective factors might overwhelm cognitive abilities in high-stake tests like the BCT.     

任务切换机制研究的理论争议与整合

任务切换是执行控制的一种重要功能。切换代价是量化执行控制持续时间的指标。并广泛应用于各个研究领域。但是切换代价在多大程度上体现了执行控制的作用,仍然还存在争论．当前主要存在任务设置重构、任务设置惯性和联结竞争三种理论。本文首先介绍了三种理论的基本观点和实验证据,以及对任务切换加工机制的分析;其次阐明了对三种理论进行整合的相关研究;最后分析了进一步研究的方向。     

Systematic behavior research for understanding consumer decision making

This study incorporates means—end chain (MEC) theory and dynamic programming for understanding the implications of consumer decision making. The conceptual framework of this study can help programmers design information systems for analyzing consumption behaviors. Such analyses will provide marketers with meaningful information for formulating marketing strategies. The main contributions of this article are as follows: (1) to enable researchers to obtain information for consumer cognitive hierarchies utilizing an information system, (2) to enhance the functions of traditional MEC methodology and provide an integrated method for analyzing consumption information, and (3) to construct an information system for analyzing consumer decision-making processes.     

盐酸戊乙奎醚对心脏瓣膜置换术患者NF-κB表达的影响

为研究盐酸戊乙奎醚对心脏瓣膜置换术患者心肌NF-κB转录活性的影响,选取择期瓣膜置换术患者60例,随机分为对照组（C）、盐酸戊乙奎醚组1（P1）、盐酸戊乙奎醚组2（P2）,每组20例。结果心肌缺血再灌注后,P1、P2组NF-κB的转录活性明显下降,可见盐酸戊乙奎醚可以抑制心肌NF-κB的激活,在一定程度上具有心肌保护作用。     

Abusive supervision, intentions to quit, and employees’ workplace deviance: A power/dependence analysis

We conducted a two-study examination of relationships between abusive supervision and subordinates’ workplace deviance. Consistent with predictions derived from power/dependence theory, the results of a cross-sectional study with employees from three organizations suggest that abusive supervision is more strongly associated with subordinates’ organization deviance and supervisor-directed deviance when subordinates’ intention to quit is higher. The results also support the prediction that when intention to quit is higher, abusive supervision is more strongly associated with supervisor-directed deviance than with organization-directed deviance. These results were replicated in a second study, a two-wave investigation of people employed in a variety of industries and occupations.     

Chicks Injected with Antisera to either S-100α or S-100β Protein Develop Amnesia for a Passive Avoidance Task

The cellular expression of S-100β protein is upregulated in Alzheimer's disease and in Down's syndrome, and this protein has been implicated in memory-related processes in laboratory animals. However, the possibility that the α subunit of S-100 is also involved in memory has not yet been examined. In the present study, day-old black Australorp white Leghorn cockerel chicks (Gallus domesticus) received injections of monoclonal antisera to S-100α (1:50) or S-100β (1:500) into each hemisphere immediately after training on a one-trial passive avoidance task. The chicks displayed significantly lower retention levels than control birds that had been injected with antisera to carbonic anhydrase, or with saline (p< .01). S-100α antisera had an amnestic effect when injected between 0 and 20 min after training, with memory deficits occurring from 30 min postlearning, at the point of transition between the A and the B phases of the Gibbs-Ng intermediate memory stage. By contrast, the S-100β antisera needed to be injected either 5 min before or immediately after training and produced amnesia 10 min earlier, at the start of the A phase of the intermediate memory stage. We conclude that the two subunits of the S-100 protein are required at different points in the sequence of events leading to the consolidation of passive avoidance memory.
