关系与IT外包绩效:服务质量调节的中介作用

基于社会资本理论,从IT外包承接商视角深入分析关系对IT外包承接商绩效的作用机制,并在此基础上考察服务质量的中介作用和关系的调节作用。以237家IT外包承接商企业高层管理者的数据为样本,运用结构方程模型对所提假设进行实证检验。结果表明:关系对IT外包承接商绩效的直接作用并不显著,以服务质量为中介变量产生间接正向影响;关系对服务质量的中介作用具有负向调节作用,即在企业关系弱的条件下,服务质量对企业绩效的作用越显著,反之亦然。     

人格测验在基于行为的绩效评估中的应用评述

随着组织行为学的兴起,作业绩效、关系绩效和团队绩效逐渐成为工作绩效考评的综合指标。近二十年实证研究已确定人格特质是预测工作绩效的一项重要指标。本研究系统总结出国内外学者对人格特质和作业绩效、关系绩效以及团队绩效的关系的研究结果,拟通过描述和分析论题的研究现状和发展趋势为今后从事有关研究提供一些启示。     

The Use of Contextual Interference Trials by Mildly Mentally Handicapped Children

The present study examined the predicted positive and linear relationship (Iwanaga, 1995a, 1995b) between exercise heart rate and music tempo preference. Initially, 128 undergraduate students (M age = 20.0 years, SD = 0.9) were surveyed to establish their three favorite music artists. A separate experimental group of 29 undergraduates (M age = 20.3 years, SD = 1.2) selected the music of a single artist from the three highest-rated artists from the earlier survey. They reported their preference for slow, medium, and fast tempo selections from each artist for three treadmill walking conditions at 40%, 60%, and 75% maximal heart rate reserve. A mixed-model 3 × 3 × 2 (Exercise Intensity × Music Tempo × Gender) analysis of variance was used to analyze the data. Results indicated there was no three-way interaction for music preference. There was, however, a significant (p < .05) two-way interaction for Exercise Intensity x Music Tempo (partial η² = .09) and a significant (p < .05) main effect for music tempo, with large differences evident between preference for medium versus slow tempo and fast versus slow tempo music at all exercise intensities (partial η² = .78). Participants reported a preference for both medium and fast tempo music at low and moderate exercise intensities and for fast tempo music at high intensity. Only partial support was found for the expected linear relationship between exercise intensity and music tempo preference.     

语境因素与语言得体--社会语言学视域下的语体观

文章以社会语言学中的言语事件分析框架为依据,探讨了何谓语言得体以及怎样做到语言得体。认为语言使用者只有洞悉主要语境因素,才能确保语言得体,才能最大限度地减少交际、尤其是跨文化交际失误。     

Multilevel Mediation With Small Samples: A Cautionary Note on the Multilevel Structural Equation Modeling Framework

Multilevel structural equation modeling (ML-SEM) for multilevel mediation is noted for its flexibility over a system of multilevel models (MLMs). Sample size requirements are an overlooked limitation of ML-SEM (100 clusters is recommended). We find that 89% of ML-SEM studies have fewer than 100 clusters and the median number is 44. Furthermore, 75% of ML-SEM studies implement 2–1–1 or 1–1–1 models, which can be equivalently fit with MLMs. MLMs theoretically have lower sample size requirements, although studies have yet to assess small sample performance for multilevel mediation. We conduct a simulation to address this pervasive problem. We find that MLMs have more desirable small sample performance and can be trustworthy with 10 clusters. Importantly, many studies lack the sample size and model complexity to necessitate ML-SEM. Although ML-SEM is undeniably more flexible and uniquely positioned for difficult problems, small samples often can be more effectively and simply addressed with MLMs.     

论语境线索在阅读理解中的作用

阅读是读者和作者以语篇为中介交流思想的过程，作者借助语篇表达自己的思想和意图，读者则需要通过推理采解读语篇的意义，领会作者的思想和意图。然而，舍理的推理必须依据语境线索进行。语境线索是指作为语境的语篇为读者解读语篇意义提供的线索。当读者在阅读过程中遇到理解障碍时，语境线索起着十分重要的作用：它们不仅可以帮助读者确定多义词的情景意义、推测生词的意义，而且还有助于推导超常搭配的隐含意义、填补信息空缺。     

Learning Environments,Family Contexts,Educational Aspirations and Attainment: A Moderation-Mediation Model Extended

In this extension of a previous study (Marjoribanks, 1999), a moderation-mediation model was constructed to examine relationships among learning environments, adolescents' educational aspirations and the educational attainment of young adults from different family contexts. Data were collected as part of a longitudinal survey of Australian youth (4382 females, 3940 males). The findings from the two investigations indicated that when distal family contexts were defined conjointly by family social status and parents' aspirations: (1) distal family contexts, academic performance and learning environments combined to have large associations with adolescents' educational aspirations; (2) distal family contexts, adolescents' learning environments and educational aspirations combined to have large associations with young adults' educational attainment; and (3) there were family-context differences in the linear and curvilinear nature of the relations among measures of individual characteristics, learning environments and educational outcomes, and these also varied between females and males in those family contexts. This revised version was published online in July 2006 with corrections to the Cover Date.     

黑格尔的思辨理性

知性超越问题即知性向理性的过渡问题是德国古典哲学面临的重大问题.黑格尔哲学的任务是要扬弃分裂,达到最高的统一整体.思辨理性是扬弃了知性思维的更高一层的理性,反思学说是理解黑格尔辩证法及思辨理性的关键.反思高于知性但尚未达到真正的理性,是知性向理性过渡的中介和桥梁.但在不少现代西方哲学家眼中,黑格尔对辨证法所作的种种理性说明基本上是无效的,黑格尔的思辨理性因此而难逃非理性主义曲解的命运.     

浅析口头交际中的明示与语境效果的获得

言语交际需要一定的语境效果;好的语境效果,有利于交际的顺延.口头交际中,语境效果的获得与发话人的明示有着直接的联系.面对不同的交际对象、交际场合,灵活变换明示方式,以期获得理想的语境效果,是发话人自然会(也必须)首先考虑的问题.本文仅从明示--推理的视角对此做了一些粗浅的分析.     

蒋介石对陶德曼调停的态度之变化

抗日战争初期,蒋介石对于陶德曼调停,先是委婉拒绝,继而表示有条件接受,最后拖延作答,前后三次做出了不同的反应。这主要是受当时战争局势、国际形势、和谈条件的变化以及自身策略考虑的影响。
