集群新创企业平行搜索风险的识别、度量与控制——基于FMEA原理

首先基于既有研究文献从领先搜索、同步搜索和跟随搜索三个方面探讨了集群新创企业平行搜索的宽度、深度和速度可能引发的典型风险。然后借助潜在失效模式与影响分析(FMEA)原理对集群新创企业平行搜索的风险模式、风险原因及风险影响进行分析,进而厘清风险度量标准并提出风险防范措施。最后通过案例分析探讨了集群新创企业平行搜索风险的识别、度量及管控过程,为集群新创企业识别、防范重点风险的实践提供参考。     

Measuring Enterprise Sustainability

The purpose of this paper is to identify the key requirements for measuring enterprise sustainability. The paper argues that measuring enterprise sustainability requires the explicit consideration of a focal firm, its supply chain and the sustainability context within which the firm operates. Building on this notion, original definitions of enterprise sustainability and enterprise sustainability performance measurement systems (ESPMSs) are proposed. The definitions provide the basis for the development of a novel conceptual framework. The framework is used to identify seven key requirements and 35 associated sub‐requirements for an ESPMS. Overall, the requirements highlight that sustainability performance measurement requires a systematic, structured and integrated approach that considers all aspects of enterprise sustainability. The framework presented in this paper is a conceptual model. In recognition of this point, the paper provides discussions on the potential application of the framework and guidance for further research. The academic, managerial and societal implications of the paper are also discussed. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment

Development of a multi-dimensional measure for assessing entrepreneurial ecosystems

ABSTRACT

Researchers and theorist have put great effort into defining and examining entrepreneurial ecosystems and how business clusters develop in certain regions. Favourable entrepreneurship ecosystems are thought to drive business and innovation. However, a commonly accepted measure of entrepreneurial ecosystem favourableness has yet to be developed. The purpose of the present research is to contribute to ecosystems research by taking a two-study approach to developing and validating a perceptual measure of entrepreneurial ecosystems. The perceptual measure is based upon prior conceptual frameworks that outline ecosystems. In developing this measure, we are able to further unpack and illuminate the factor structure of ecosystems, the results of which have direct scholarly and practitioner uses.

基于OpenCV的物体轮廓尺寸测量

针对现有无人快递机器人对于快递物品进行尺寸测量的缺乏,提出了一种基于OpenCV的机器视觉测量方法,通过对图片进行预处理,利用Canny算法进行边缘检测,对物体的轮廓尺寸进行测量。通过添加修正系数对测量系统进行改进,通过前后两次测量数据对比,该测量系统精度得到显著提高,为无人快递机器人提供了更准确的测量方法。

Performance Differences in German Higher Education: Empirical Analysis of Strategic Groups

Initial investments and different strategic actions of universities lead to their different positions in the higher education sector. Pursuing similar strategies leads to similar positions that influence structure and performance within the system. Institutions cannot only choose to focus on research or on teaching, but also to focus either on natural sciences or social sciences. Using 73 public universities in Germany, this paper examines the existence of strategic groups based on performance. Common strategic variables only partly determine performance in high and low efficiency groups.     

陈家山煤矿425综放工作面贯通控制测量浅析

煤矿井下测量工作是煤矿生产过程中必不可少的一个重要环节,由于井下巷道纵横交错,贯通测量更是重中之重。特别是在走向长工作面中,由于工作面走向长度超过2公里。加之与相邻工作面其它巷道之间留设煤柱的间距为30米。这就对测设工作带来诸多不便,从布点、导线测量、内外业计算、成果整理、精度评定等过程,必须注重测量的每个环节。同时巷道放线开口要符合设计,准确标定施工要素,才能实现安全贯通、安全生产,防止误透事情的发生。     

Cultural distance in international business and management: from mean-based to variance-based measures

Extant practice in international management is to measure cultural distance as a nation-to-nation comparison of country means on cultural values, thereby ignoring the cultural variation that exists within countries. We argue that these traditional mean-based measures of cultural distance should take within-country cultural variation into account. Therefore, we propose the use of variance-based measures of cultural distance. To illustrate our argument, we examine total US foreign affiliate sales in more than 40 host countries over the 1983–2008 period, complemented with data from the World Values Survey. We analyze the effects of three cultural distance measures: the Kogut and Singh (1988 Kogut, B., and Singh, H. (1988), ‘The Effect of National Culture on the Choice of Entry Mode,’ Journal of International Business Studies, 19, 411–432.[Crossref], [Web of Science ®] , [Google Scholar]) mean-based index of cultural distance, the Kogut and Singh (1988 Kogut, B., and Singh, H. (1988), ‘The Effect of National Culture on the Choice of Entry Mode,’ Journal of International Business Studies, 19, 411–432.[Crossref], [Web of Science ®] , [Google Scholar]) index conditioned by host-country cultural variation and a variance-based measure that takes into account both home- and host-country cultural variation. Our findings indicate that, when within-country cultural variation is taken into account, the explanatory power of the Kogut and Singh (1988 Kogut, B., and Singh, H. (1988), ‘The Effect of National Culture on the Choice of Entry Mode,’ Journal of International Business Studies, 19, 411–432.[Crossref], [Web of Science ®] , [Google Scholar]) index is substantially decreased. In addition, our variance-based measure of cultural distance outperforms the Kogut and Singh (1988 Kogut, B., and Singh, H. (1988), ‘The Effect of National Culture on the Choice of Entry Mode,’ Journal of International Business Studies, 19, 411–432.[Crossref], [Web of Science ®] , [Google Scholar]) measure in the explanation of foreign US sales. We therefore suggest to move from mean-based to variance-based measures of cultural distance, thereby taking the cultural variation within countries into account.
