中国跨国公司外派人员多目标主动行为的前因与后果——挑战性-阻碍性压力视角

传统研究强调跨文化多重压力阻碍外派成功, 但相对忽视压力具备的动力作用。该研究基于挑战性-阻碍性压力视角, 遵循“压力-动机-行为-结果”的逻辑框架, 对中国跨国公司外派人员多目标主动行为及结果的产生机制展开研究。依据自我决定理论分析挑战性-阻碍性两种不同属性压力如何通过影响动机和主动行为进而影响外派人员的职业发展、工作绩效及组织绩效的过程, 并根据工作要求-控制模型, 从组织和工作资源两方面识别两种压力影响外派结果的边界条件, 以及跨文化背景下主动行为发挥作用的边界条件。该研究揭示外派主动动机及行为在高不确定性跨文化背景下的价值功效, 可以为中国跨国公司挑选、培训、激励和保留国际化人才提供实践的参考。     

从主文化视角看20世纪我国社会道德规范体系的演变与重建

根据社会学关于主文化的理论观点,可以将主义化细分为主导文化、主体文化、主流文化.回顾20世纪中国文化的发展历程,可以看到,主文化在三个维度上一直处在消长与变革之中,并由此使社会道德规范体系呈现出相应的演变历程.针对改革开放后我国社会道德规范体系"碎片化"的态势,要大力建设以"社会主义和谐文化"为标志的主文化,紧紧抓住社会主义核心价值体系这个根本,尊重差异、包客多样,构建中国特色社会主义道德规范体系.     

The aging decision maker: cognitive aging and the adaptive selection of decision strategies

Are older adults' decision abilities fundamentally compromised by age-related cognitive decline? Or can they adaptively select decision strategies? One study (N = 163) investigated the impact of cognitive aging on the ability to select decision strategies as a function of environment structure. Participants made decisions in either an environment that favored the use of information-intensive strategies or one favoring the use of simple, information-frugal strategies. Older adults tended to (a) look up less information and take longer to process it and (b) use simpler, less cognitively demanding strategies. In accordance with the idea that age-related cognitive decline leads to reliance on simpler strategies, measures of fluid intelligence explained age-related differences in information search and strategy selection. Nevertheless, both young and older adults seem to be equally adapted decision makers in that they adjust their information search and strategy selection as a function of environment structure, suggesting that the aging decision maker is an adaptive one.     

Age difference in numeral recognition and calculation: an event-related potential study.

In this study, we investigated the age difference in numeral recognition and calculation in one group of school-aged children (n = 38) and one of undergraduate students (n = 26) using the event-related potential (ERP) methods. Consistent with previous reports, the age difference was significant in behavioral results. Both numeral recognition and calculation elicited a negativity peaking at about 170-280 ms (N2) and a positivity peaking at 200-470 ms (pSW) in raw ERPs, and a difference potential (dN3) between 360 and 450 ms. The difference between the two age groups indicated that more attention resources were devoted to arithmetical tasks in school-aged children, and that school-aged children and undergraduate students appear to use different strategies to solve arithmetical problems. The analysis of frontal negativity suggested that numeral recognition and mental calculation impose greater load on working memory and executive function in schoolchildren than in undergraduate students. The topography data determined that the parietal regions were responsible for arithmetical function in humans, and there was an age-related difference in the area of cerebral activation.     

Chinese kindergartners’ automatic processing of numerical magnitude in Stroop-like tasks

Using Stroop-like tasks, this study examined whether Chinese kindergartners showed automatic processing of numerical magnitude. A total of 36 children (mean age 5 5 years 10 months) were asked to perform physical size comparison (i.e., “Which of two numbers is bigger in physical size?”) and numerical magnitude tasks (i.e., “Which of two numbers is bigger in numerical magnitude?”) on 216 number pairs. These number pairs varied in levels of congruence between numerical magnitude and physical size (for Stroop effect) and numerical distance (for distance effect). On the basis of analyses of response time and error rates, we found that Chinese kindergartners showed automatic processing of numerical magnitude. These results are significantly different from previous studies’ findings about the onset age (ranging from around the end of first grade to third grade) for automatic processing of numerical magnitude.     

结直肠癌诊断模式的若干思考

结直肠癌是常见的消化道恶性肿瘤,然而在临床上得到诊断时大多已经到了中晚期,错过了最佳的治疗时机.近年来,随着基因相关技术及生物信息技术的迅猛发展,结直肠癌诊断方法得到不断改进,但早期诊断仍不尽如人意.因此现有的诊断模式值得我们去深思,从哲学意义上探索更为完善的诊断模式.

The ameliorating effect of oroxylin A on scopolamine-induced memory impairment in mice

Oroxylin A is a flavonoid and was originally isolated from the root of Scutellaria baicalensis Georgi., one of the most important medicinal herbs in traditional Chinese medicine. The aim of this study was to investigate the ameliorating effects of oroxylin A on memory impairment using the passive avoidance test, the Y-maze test, and the Morris water maze test in mice. Drug-induced amnesia was induced by administering scopolamine (1 mg/kg, i.p.) or diazepam (1 mg/kg, i.p.). Oroxylin A (5 mg/kg) significantly reversed cognitive impairments in mice by passive avoidance and the Y-maze testing (P<.05). Oroxylin A also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze (P<.05). Moreover, the ameliorating effects of oroxylin A were antagonized by both muscimol and diazepam (0.25 mg/kg, i.p., respectively), which are GABA(A) receptor agonists. Furthermore, oroxylin A (100 microM) was found to inhibit GABA-induced inward Cl(-) current in a single cortical neuron. These results suggest that oroxylin A may be useful for the treatment of cognitive impairments induced by cholinergic dysfunction via the GABAergic nervous system.     

情绪对学习不良青少年选择性注意和持续性注意的影响

以学习不良青少年为被试,采用成绩反馈法诱发情绪,考察了情绪对学习不良青少年选择性注意和持续性注意的影响,结果表明：（1）情绪会影响学习不良青少年的选择性注意,具有积极低唤醒情绪的学习不良青少年,他们的选择性注意的反应时显著短于消极情绪下的被试;(2)学习不良青少年的情绪会影响到他们的持续性注意能力,消极高唤醒的情绪能够增加虚报率,而积极高唤醒的情绪能够提高判断标准,降低虚报率
