The ambidexterity framework, which comprises two contradictory, yet interrelated processes of exploration and exploitation, has been researched using a variety of perspectives. Few studies, however, provide insight into the question: how is ambidexterity managed across multiple organizational levels? To address this question, we introduce the term ambidexterity penetration that refers to the enactment of ambidexterity across multiple organizational levels and develop a conceptual framework about how it is practiced (horizontally, vertically and organizationally). We empirically showcase this framework using findings from six business units of an aerospace and defense organization and analyzing data from 30 interviews. Overall, our study contributes to ambidexterity research and offers an empirical investigation of ambidexterity penetration across multiple organizational levels in the context of the aerospace and defense sector. 相似文献

针对在发展职业教育中所出现的问题和偏见,提出要建立大职教体系的主张.把职教作为与普教并列的体系来看待,认为职教有自己独立的办学宗旨和培养目标,这是知识经济时代技术高深化和职业教育的性质与特点所决定的;是提高技术人才培养质量的需要.为此,要建立起真正具有职业教育意义的本科和研究生层次的办学方式,并改革职业教育的课程体系以实现阶段性与连续性的统一,在外部条件上要建立起适合大职教体系独立发展的评价氛围和政策环境,实现职教体系与普教体系的互通,同时,对进入职业教育各办学层次的方式也作了从实际出发的探索. 相似文献

The standard hypothesis testing procedure in meta-analysis (or multi-center clinical trials) in the absence of treatment-by-center
interaction relies on approximating the null distribution of the standard test statistic by a standard normal distribution.
For relatively small sample sizes, the standard procedure has been shown by various authors to have poor control of the type
I error probability, leading to too many liberal decisions. In this article, two test procedures are proposed, which rely
on thet—distribution as the reference distribution. A simulation study indicates that the proposed procedures attain significance
levels closer to the nominal level compared with the standard procedure. 相似文献

文章结合十六大文件的深入学习,透视了当代文化产业遭遇的各种现实尴尬,并对一系列相关的理论与实践问题展开了学理性追问,包括当代西方马克思主义美学和19世纪的传统马克思主义美学的相关论述,着重分析了当代文化生产的四个重要特征:即不间断的意识形态再生产的商品化特征,以符号作手段以传媒为载体进行市场流通的特征,个性化与标准化及原创性与复制性的综合过程特征,在多次体验消费中获得价值增值的特征。 相似文献

The contemporary retreat from marriage in the United States has had a differential impact across socioeconomic and racial groups. Here, 1990 marriage rates and propensities for Virginia, North Carolina, and Wisconsin are analyzed regarding (a) the likelihood that persons in different groups ever marry and (b) patterns of partner choice with respect to race and educational level. Marriage remains strong in most race‐education groups but is substantially lower among Blacks and among those with less than 12 years of education. Patterns of partner choice have shifted to show greater symmetry between the educational levels of brides and grooms. Changes have been modest with regard to the level and pattern of interracial (Black‐White) marriage. Marriage is increasingly a union of equals, but a union chosen more by Whites than by Blacks and more by the well educated than by the poorly educated. 相似文献

Conventional globalization theory states that regional economic integration will precede price standardization across participating countries due to the increased buying power of large retail groups and parallel imports. The resulting price corridor should merely reflect differences in logistic costs and short-term, local competitive actions. Yet, this study uses panel data from 25 European countries to examine how hefty food and beverage price differentials between regions remained constant over the last decade. Income, store productivity, and market concentration all contribute to the explanation for regional price differences. These findings suggest that, contrary to straight-line globalization theory, large European retailers’ decisions can influence price convergence and maintain important price dispersion between economically integrated countries. We provide recommendations to enhance market integration. 相似文献

Bailey has shown that choice of certain trigonometlk levels for factors in a symmetrical confounded factorial design is more efficient for quantitative treatments. This paper introduces certain incidence matrices associated with the flats of different pencils of such designs to obtain an explicit expression for the efficiency and also gives a simpler derivation of Bailey's results. 相似文献
