This paper presents a new widely applicable omnibus test for discrete distributions which is based on the difference between the integrated distribution function Ψ(t)=∫t ∞ (1−F(x))dx and its empirical counterpart. A bootstrap version of the test for common lattice models has accurate error rates even for small samples and exhibits high power with respect to competitive procedures over a large range of alternatives.

Literature on academic spin-offs gives evidence of different modes of interaction between spin-offs and their parent and their relative role in different modes of knowledge production. In this article, we examine the development of interactions between academic spin-offs and their parent organizations over a mid- to long-term period (4–15 years), drawing on a series of 25 case studies of spin-off/parent pairs from France and Switzerland. We show that the relational trajectories can be captured by four major dynamic patterns. These patterns range from an early cut-off of interactions in line with a linear model of innovation to sustained interactions supporting joint production of knowledge. Some patterns even include a change in the mode of knowledge production over time. In addition, we identify a number of determinants, internal or external to the pair, affecting the dynamic pattern. We conclude that management of spin-off processes and support policies for academic spin-offs should embrace this dynamic diversity. 相似文献

The present paper reports the results of a vignette- and questionnaire-based research project investigating the influence of Moral Intensity (MI) on decision making in a New Zealand business context. The use of a relatively sensitive research design yielded results showing that – in contrast to previous research – objective manipulations, as well as subjective perceptions, of three of the six MI components were of particular importance in accounting for a comparatively large proportion of the variation in four outcome variables. There were no interactions of appreciable magnitude between MI components, or variations across scenarios. Also, no support was found for a reliable multi-dimensional structure of perceptions of Moral Intensity. Implications of the findings are discussed. 相似文献

Project motivation is a key aspect to a successful project, yet few studies exist that shed light on this important subject. This article reviews the current literature and theoretical aspects of motivation and provides an analysis of the data. A survey was conducted by soliciting project managers to tell how they perceive their ability to influence motivation. In total, 115 certified project managers responded to the survey. A discussion and suggestions for future research follow the data. 相似文献

Viele Umfragen deuten auf eine massive Abwanderung des deutschen Mittelstands in die neuen EU-Beitrittsl?nder hin. Inwieweit
kann dieser Exodus empirisch untermauert werden? In welchen Aktivit?ten engagieren sich die deutschen mittelst?ndischen Unternehmen
in den Beitrittsl?ndern? Welche Chancen und Risiken erwarten sie von der Osterweiterung? 相似文献

Many developing countries are currently considering liberalisation of external capital flows. While the ultimate objective of financial opening is to raise efficiency and growth, the reform process must be carefully designed to achieve these results. A recent conference has discussed the policy choices. 相似文献
