EMPLOYEE SELF-SERVICE TECHNOLOGY ACCEPTANCE: A COMPARISON OF PRE-IMPLEMENTATION AND POST-IMPLEMENTATION RELATIONSHIPS

Implementation of employee self-service (ESS) technology presents a variety of challenges for organizations as they strive to maximize return on investment and change management. Using a research framework grounded in the theory of planned behavior, this study examines factors that enhance user acceptance of ESS technology both before and after implementation. Results suggest that employees are more likely to intend to use ESS technology when they have positive attitudes toward using it and when subjective norms in the organization support use of the technology. Perceived organizational support (POS) enhanced the effect of managerial pressure on perceptions of normative beliefs supporting use of the technology post-implementation. Implications of the research and future research directions are discussed.     

《乾卦》爻辞中星宿信息钩沉

先贤用天象来解释乾卦六龙,但由于未涉及具体的星宿证据,不能断定乾卦爻辞只能来自与苍龙有关的天象。本文发现乾卦爻辞中按天象出现的先后顺序,除了容易被泛哲理化解释的“龙”之外,还隐含着五个星宿信息,即天田、健闭、天渊、鱼、天渊,因此可断言这些爻辞的原型来自天象。     

流动儿童的问题行为与人格、家庭功能的关系

以北京市806名流动儿童和319名城市儿童为被试,采用问题行为问卷、小五人格问卷和家庭功能问卷,考察流动儿童问题行为的特点及其与城市儿童的差异,并探讨人格和家庭功能对流动儿童问题行为的影响。结果发现:(1)流动儿童内、外化问题行为的自我报告率分别达到了31.0%2、0.1%,与城市儿童相比,流动儿童的内化问题行为较为突出。(2)人格的情绪性、开放性显著正向预测流动儿童的内化问题题行为,外向性、家庭功能的亲密度显著负向预测其内化问题行为,情绪性、开放性显著正向预测流动儿童的外化问题行为,宜人性、谨慎性、亲密度显著负向预测外化问题行为。(3)人格在家庭功能的亲密度与内化问题行为之间起部分中介作用,在亲密度与外化问题行为之间起完全中介作用。     

人际交往能力与生命意义的关系:孤独感和年级的作用

基于存在主义心理学理论,本研究采用人际交往能力问卷、孤独感量表和生命意义量表对福建省三所大学的1476名大一和大二学生进行调查,考察人际交往能力与生命意义的关系,以及孤独感的中介作用和年级的调节作用。结果表明：（1）交往能力和孤独感存在显著的性别差异。男生的交往能力显著高于女生,孤独感显著低于女生;（2）交往能力与孤独感呈显著负相关,与拥有意义和追寻意义均呈显著正相关,而孤独感与它们均呈显著负相关;（3）孤独感在交往能力与拥有生命意义之间的中介作用受到年级的调节。与大二学生相比,大一新生孤独感的中介效应更大。研究结果在一定程度上揭示了交往能力对生命意义的作用过程,为针对性提升大学新生生命意义提供方向指导和实证依据。     

中药注射剂有效性及“毒性”的物质基础分析

中药注射剂的有效性得到了临床用药的广泛验证,但带来的安全性（“毒性”）问题也引起业界和社会的广泛关注。本文通过分析中药注射剂和同处方的口服剂有效性和“毒性”的特点,认为中药注射剂的有效性来自于小分子物质,而大分子物质则是导致“毒性”的主要物质基础,进而提出从严监控中药注射剂中的大分子物质是提高中药注射剂的有效策略。     

Learning a two-cue inference task when one of the cue-criterion relations is known

Learning two-cue probability learning (MPL) tasks when the functional relation between the first cue and the criterion was known to the subject was studied in a factorial experiment. Contrary to the predictions from a hypothesis sampling model assuming independent learning of each cue in MPL, the function form for the first cue was found to affect learning of the second cue, facilitating it when the functional relations were the same for both cues and inhibiting it when the functions were different. These results suggest that it is not possible to extrapolate findings from single-cue probability learning directly to MPL.     

Hemispheric asymmetry effects in children studied by dichotic listening and visual half-field testing

Dichotic listening (DL) and visual half-field (VHF) testing were used to study hemisphere asymmetry in a developmental perspective. Five-, 8-, and 11-year-old children were presented lists of fused words using a DL technique in Experiment 1, and 8- and 11-year-old children were presented pictures of common objects using a VHF technique in Experiment 2. In both experiments, measures of identification, free recall, and recognition of the words/pictures were employed. The results revealed effects of ear input (right-ear advantage) and half-field presentation (right visual half-field advantage) for all age groups, although the magnitude of this lateralization effect differed between the three memory measures. The results are discussed in relation to developmental aspects of language laterality, and in relation to the clinical utility of non-invasive lateralization techniques.
