道德外语效应的三种机制及与外语水平的关系

道德外语效应(Moral Foreign Language effect)是指人们的道德判断在外语条件下发生改变的现象,自该效应提出以来,其背后的机制一直都是研究的热点。道德外语效应的解释机制主要有审慎加工增强、情绪反应减少和道德规范联结的减弱等。本文对三种影响机制进行了探讨,发现情绪、道德规范和外语水平对道德判断可能会产生影响。同时,本文指出未来可以从自我控制、认知启动效应、消极情绪启动效应及道德规范与外语水平之间的关系进行研究和探讨。     

Self-referential tags in the discourse of people with Alzheimer's disease

In a study of the discourse of 100 people with Alzheimer's disease treated for 12 months with donepezil, we observed that, as a group, they used a form of tag, described here as a self-referential tag (SRT), 14 times more frequently than did caregivers. Patients use SRTs to check propositions dependent on episodic memory as in I haven't seen the doctor recently, have I? and to monitor information flow as in I told you that already, didn't I? Based on criteria developed for distinguishing checking from monitoring tags, we document the type and frequency of patients' SRT use in the ACADIE corpus and analyze these in relation to standard measures of cognitive function (Mini Mental State Exam and Alzheimer's Disease Assessment Scale-cognitive sub-scale) at baseline and 12 months. Patients using monitoring SRTs (N=31), with or without checking SRTs, show significantly better cognitive test scores at 12 months, than are seen in patients who never use tags (N=29), or who only use checking tags (N=40). SRT use may be an independent measure of potential treatment responsiveness.     

The Mother–Daughter Relationship as a Resource for Korean Women's Career Aspirations

Korean college women's career aspirations were examined among 482 Korean college women in South Korea. The inability of women to envision themselves in a career has been largely attributed to formal education that perpetuates gender inequality. As such, this study investigated the inter-relationships between external factors (school experiences and peer influences) and internal factors (maternal influences with the mother–daughter relationship) in Korean women's development of self-perception and in the significance of their sex-role behaviors (career orientation and feminist identification). The structural equation model (SEM) utilized in this study revealed that Korean women's career orientation was determined directly by their nontraditional sex-role attitudes and by a close, continuous, and satisfactory relationship with their mothers. Overall, maternal influences on the development of daughters' career orientation outweigh other factors encountered in schools, and emerge as key predictor variables in Korean women's career development.     

Differential effect of TEA on long-term synaptic modification in hippocampal CA1 and dentate gyrus in vitro.

The effectiveness of tetraethylammonium (TEA) and high-frequency stimulation (HFS) in inducing long-term synaptic modification is compared in CA1 and dentate gyrus (DG) in vitro. High-frequency stimulation induces long-term potentiation (LTP) at synapses of both perforant path-DG granule cell and Schaffer collateral-CA1 pyramidal cell pathways. By contrast, TEA (25 mM) induces long-term depression in DG while inducing LTP in CA1. The mechanisms underlying the differential effect of TEA in CA1 and DG were investigated. It was observed that T-type voltage-dependent calcium channel (VDCC) blocker, Ni2+ (50 microM), partially blocked TEA-induced LTP in CA1. A complete blockade of the TEA-induced LTP occurred when Ni2+ was applied together with the NMDA receptor antagonist, D-APV. The L-type VDCC blocker, nifidipine (20 microM), had no effect on CA1 TEA-induced LTP. In DG of the same slice, TEA actually induced long-term depression (LTD) instead of LTP, an effect that was blocked by D-APV. Neither T-type nor L-type VDCC blockade could prevent this LTD. When the calcium concentration in the perfusion medium was increased, TEA induced a weak LTP in DG that was blocked by Ni2+. During exposure to TEA, the magnitude of field EPSPs was increased in both CA1 and DG, but the increase was substantially greater in CA1. Tetraethylammonium application also was associated with a large, late EPSP component in CA1 that persisted even after severing the connections between CA3 and CA1. All of the TEA effects in CA1, however, were dramatically reduced by Ni2+. The results of this study indicate that TEA indirectly acts via both T-type VDCCs and NMDA receptors in CA1 and, as a consequence, induces LTP. By contrast, TEA indirectly acts via only NMDA receptors in DG and results in LTD. The results raise the possibility of a major synaptic difference in the density and/or distribution of T-type VDCCs and NMDA receptors in CA1 and DG of the rat hippocampus.

青少年饮酒期望与饮酒行为的关系:追踪研究的证据

通过对1000余名青少年为期一年的追踪调查,探讨了青少年饮酒期望与饮酒行为之间的关系,同时考察了饮酒期望的发展和性别差异。研究结果表明:(1)一年来青少年的饮酒行为、饮酒消极期望和饮酒积极期望都显著增加;女生的饮酒行为和饮酒积极期望的增加都显著高于男生。(2)第二次测查时,青少年的饮酒行为、饮酒积极期望和饮酒消极期望高于一年前原同年级的学生。(3)饮酒积极期望、消极期望和饮酒行为之间的基本关系一年来没有发生变化:消极期望可能降低饮酒行为,积极期望可能增加饮酒行为,消极期望对积极期望与饮酒行为的关系具有显著的调节作用。但是消极期望对饮酒行为的作用降低,积极期望的作用升高。     

经世致用：仍主宰着近代中医方书的发展
