翻译者,背叛者?

忠实不必是普遍的伦理要求和译者必须达到的目标。译者有两个选择：做一个忠实者或背叛者。如果是前一个选择,译者必须尽可能地深入原文;如果是后一个选择,译者必须对他的动机和行为做出有效的辩护。译者的选择决定了原文意义的折射方向、译文的基本面貌和读者的见解空间。在一个全球交往的时代,译者必须认真对待并谨慎行使自己的＂译者权力＂。     

演绎推理的认知和脑机制研究述评

演绎推理是指假设在某些前提成立的条件下推测必然会出现的结论,它是人类重要的思维形式.不同的认知理论对人在推理过程中表现出的逻辑和非逻辑特性作出了相应的解释和预测,而来自认知神经科学的研究也进一步揭示了推理行为的脑机制,对演绎推理的认知理论进行了验证和发展.本文通过对国内外有关演绎推理认知与脑机制研究现状的回顾,以期能促进该领域研究的不断深入.     

机器理解古汉语的实验和若干问题

本文介绍了机器理解古汉语的一个实验系统(ACLUS)。该系统由一个知识库和三个子程序组成。知识库包含有一部机器词典和若干集用来加工句子的规则。三个子程序是:句法分析子程序、翻译子程序和问答子程序,它们分别执行三种不同的功能。本文还讨论了有关机器理解古汉语的若干重要问题。     

An analysis of fidgeting and associated individual differences

Fidgeting was defined as engaging in manipulations of one's own body parts or other objects, such actions being peripheral or nonessential to central ongoing events or tasks Two studies employed preliminary fidgeting questionnaires of 70 and 106 items, respectively, tapping a wide range of habitual behaviors Item selection and factor analyses led to the development of a final, 40-item, individual difference measure of fidgeting tendency which is balanced for response bias and has an alpha reliability coefficient of 89 Convergent and construct validity were supported by positive correlations between the fidgeting tendency measure and measures of tendencies to engage in extraneous activities (consuming alcoholic drinks, cigarette smoking, eating, daydreaming, restlessness, insomnia) while preoccupied with certain situations and tasks These findings implied that fidgeting is an activity overflow and that it is more probable when the organism's physical activity is constrained by the central or focal act Fidgeting tendency also correlated positively with binge eating and with physical activity In two additional studies, questionnaire fidgeting tendency scores correlated positively with direct observations of fidgeting by subjects and with peer predictions Personality correlates of fidgeting tendency were well defined More fidgety persons were more unpleasant and more arousable (i e, more anxious or hostile) Fidgeting tendency did not correlate significantly with subject sex or with arousal-seeking tendency     

The social-encoding benefit in face recognition is generalized to other-race faces

Faces are visual stimuli that convey rich social information. Previous experiments found better recognition for faces that were evaluated based on their social traits than on their perceptual features during encoding. Here, we ask whether this social-encoding benefit in face recognition is also found for categories of faces that we have no previous social experience with, such as other-race faces. To answer this question, we first explored whether social and perceptual evaluations for other-race faces are consistent and valid. We then asked whether social evaluations during encoding improve recognition for other-race faces. Results show that social and perceptual evaluations of own- and other-race faces were valid. We also found high agreement in social and perceptual evaluations across individuals from different races. This indicates that evaluations of other-race faces are not random but meaningful. Furthermore, we found that social evaluations facilitated face recognition regardless of race, demonstrating a social-encoding benefit for both own- and other-race faces. Our findings highlight the role of social information in face recognition and show how it can be used to improve recognition of categories of faces that are hard to recognize due to lack of experience with them.     

Unconscious structural knowledge of tonal symmetry: Tang poetry redefines limits of implicit learning

The study aims to help characterize the sort of structures about which people can acquire unconscious knowledge. It is already well established that people can implicitly learn n-grams (chunks) and also repetition patterns. We explore the acquisition of unconscious structural knowledge of symmetry. Chinese Tang poetry uses a specific sort of mirror symmetry, an inversion rule with respect to the tones of characters in successive lines of verse. We show, using artificial poetry to control both n-gram structure and repetition patterns, that people can implicitly learn to discriminate inversions from non-inversions, presenting a challenge to existing models of implicit learning.     

Latent variable selection in multidimensional item response theory models using the expectation model selection algorithm

The aim of latent variable selection in multidimensional item response theory (MIRT) models is to identify latent traits probed by test items of a multidimensional test. In this paper the expectation model selection (EMS) algorithm proposed by Jiang et al. (2015) is applied to minimize the Bayesian information criterion (BIC) for latent variable selection in MIRT models with a known number of latent traits. Under mild assumptions, we prove the numerical convergence of the EMS algorithm for model selection by minimizing the BIC of observed data in the presence of missing data. For the identification of MIRT models, we assume that the variances of all latent traits are unity and each latent trait has an item that is only related to it. Under this identifiability assumption, the convergence of the EMS algorithm for latent variable selection in the multidimensional two-parameter logistic (M2PL) models can be verified. We give an efficient implementation of the EMS for the M2PL models. Simulation studies show that the EMS outperforms the EM-based L₁ regularization in terms of correctly selected latent variables and computation time. The EMS algorithm is applied to a real data set related to the Eysenck Personality Questionnaire.     

“增益”还是“损耗”?挑战性工作要求对工作-家庭增益的“双刃剑”影响

基于资源保存理论和不确定管理理论, 采用日记研究法收集81个样本10个工作日的数据, 从静态和动态两个视角, 通过明晰挑战性工作要求的不同属性(每日水平、平均水平、日间变动、波动变化), 全面检验了挑战性工作要求对工作-家庭增益的影响。研究结果表明：(1)在静态模型中, 挑战性工作要求通过工作专注度(增益路径)和放松(损耗路径)作用于工作-家庭增益, 且在个体间的平均水平模型中, 放松的中介作用更为显著; (2)在动态模型中, 挑战性工作要求的日间变动和波动变化, 均通过减少员工工作专注度和放松, 进而降低工作-家庭增益。最后, 本研究讨论了管理者应重视挑战性工作要求的双刃剑作用等实践启示。     

角色压力、工作家庭冲突和心理抑郁的中美比较--社会支持的调节作用

在中国和北美两个样本中,探讨了工作家庭冲突模型的共性和差异。首先使用多组验证性因子分析找到适用于中美样本的模型,然后采用结构方程模型和多层次回归进行假设检验。结果显示,中美员工感知到的工作-家庭(家庭-工作)冲突在工作(家庭)角色压力和心理抑郁的关系中都起中介作用。此外,情境的差异导致中美员工在工作支持和家庭支持的调节作用上有不同的表现,即中国员工感受到的工作(家庭)支持对角色压力和冲突间关系的调节作用不显著,在北美样本中,工作支持负向调节工作角色压力到工作-家庭冲突的关系,而工作支持和家庭支持正向调节家庭角色压力到家庭-工作冲突的关系。本文的发现能够帮助管理者意识到情境因素的重要作用,从而制定更为有效的管理决策。     

On Pretabular Logics in NExtK4 (Part I)

This paper partly answers the question “what a frame may be exactly like when it characterizes a pretabular logic in NExtK4”. We prove the pretabularity crieria for the logics of finite depth in NExtK4. In order to find out the criteria, we create two useful concepts—“pointwise reduction” and “invariance under pointwise reductions”, which will remain important in dealing with the case of infinite depth.
