Friederike Welter Lutz Trettin Uwe Neumann 《The International Entrepreneurship and Management Journal》2008,4(2):109-128
During the last decade entrepreneurship research has focused increasingly on spatial aspects of entrepreneurship. Many systematic
studies have been conducted on the national or regional scale, although other geographical scales—cities and their single
districts and neighbourhoods—have drawn less attention. In this context, the paper aims, firstly, at identifying spatial success
factors of entrepreneurial activities and their promotion at the local scale. Secondly, the paper aims at contributing to
the development of a conceptual frame at the interface of entrepreneurship research, urban and economic geography, and regional
economics. Empirically, the paper draws on results from explorative case studies in two distressed urban areas. 相似文献

Quality function deployment (QFD) is comprised of two major group decision-making processes. One is to collect the customer
requirements from a group of customers, whereas the other is to determine the relationship between customer requirements and
technical measures by a cross-functional team. Generally, different and/or even subjective opinions are quite often in a group
decision-making process due to the limitations of experience and impreciseness. Obviously, the importance of each customer
requirement and the relationship between customer requirements and technical measures are determined by a group of people
with imprecision and vagueness. Under such circumstances, a fuzzy group decision-making approach can be applied in QFD to
deal with a group decision-making process when the information is imprecise and fuzzy. Moreover, an example is provided as
well as the computational steps to show this fuzzy group decision-making approach can be effectively used in QFD to make decisions
with imprecision and vagueness. 相似文献

Data driven test procedure for detection of change is introduced and its properties are studied. The new solution is max-type
statistic related to data-driven rank tests for two-sample subproblems. Simulations show that the new test possesses high
and stable power. The test is consistent at essentially any alternative. Asymptotic null distribution of the test is derived.

Robert G. Chambers 《Journal of Productivity Analysis》2008,30(2):107-120
Stochastic productivity indicators are defined, and superlative measures of these indicators are derived. It is shown that,
in the presence of complete markets or a common-expectations equilibrium, differences in the market values of firms are superlative
indicators of cross-sectional productivity differences. Exactness results are used to decompose nonstochastic productivity
indicators into a measure of true productivity change and a measure of ‘luck’. The decomposition is illustrated empirically.
