Overcrowding satisfies the physician's criteria for a disease—of society, caused by the lack of a doctrine for the future. This article is a clinical examination of the disease, its symptoms, pathogenesis, diagnosis and treatment.  相似文献

The partial correlation is a commonly used measure for assessing the bivariate correlation of two quantitative variables after eliminating the influence of one or more other variables. The partial correlation is generally interpreted as the correlation that would result if the variables to be eliminated were fixed (not allowed to vary and influence the other variables), which is referred to in the statistical literature as conditional correlation. The present paper demonstrates, by means of theoretical derivations and practical examples, that when the assumption of multivariate normality is violated (e.g., as a result of nonlinear relationships among the variables investigated) the usual interpretation of the partial correlation coefficient will be basically incorrect. In extreme cases the value of the partial correlation coefficient may be strongly positive, close to 1, whereas the conditional correlation may have a large negative value. To solve this problem the paper suggests to partial out a certain function (in most cases the square) of the variables whose effects are to be eliminated if nonlinear relationships are likely to occur.  相似文献

Product innovation is the result of a constant interaction between the in‐house research and development (R&D) department and knowledge exchanges with the firm's environment. Knowledge exchanges come in different forms. They break down into information gathering applied in new product development, research cooperation on particular innovation projects, and managing information outflows allowing the consequent appropriation of the results of product innovation through specific methods. The way firms handle knowledge exchanges affects their performance. This paper looks at three related indicators of performance: (1) research intensity (a measure of innovative input); (2) the share of revenue realized through innovative product sales (a measure of innovative output); and (3) their impact on the growth in total revenue. The bulk of the econometric literature looking into these matters only allows general statistical statements on the behavior of an “average” firm. This paper takes on another view by using the quantile regression method to stress the heterogeneity of innovative firms in their dealing with knowledge exchange and the effect this has on their performance. A first key finding is that research intensity is positively influenced by knowledge externalities, research cooperation, and appropriability, and it is through this that these variables affect innovative revenue and also the growth in total revenue. By using quantile regression these relationships are further refined to screen for differences in behavior between dynamic and lagging innovators. This refinement indicates that, in the case of research intensity, the knowledge externalities gain in importance in the higher quantiles and are insignificant in the lower ones. Next, research cooperation remains important in all quantiles, but a higher significance is observed in the higher quantiles as well. Finally, appropriability is extremely important for the lower quantiles, but it becomes insignificant in the highest. These findings corroborate the assumptions made in the literature on open innovation: knowledge externalities and research collaboration are vital for those opening up their firm for new ideas and who are, at the same time, reluctant to protect their findings through specific appropriation measures. In the case of innovative revenue all variables on knowledge exchange operate through the research intensity irrespective of the quantile, although the impact of research intensity on this type of revenue is higher in the upper quantiles. As for the growth in revenue, the effect of the innovative revenue is, again, higher in the higher quantiles. This suggests that dynamic product innovators have the most efficient R&D process and the strongest growers are so, especially, because they are successful product innovators.  相似文献

Sustainable development (SD) – that is, “Development that meets the needs of current generations without compromising the ability of future generations to meet their needs and aspirations” – can be pursued in many different ways. Stakeholder relations management (SRM) is one such way, through which corporations are confronted with economic, social, and environmental stakeholder claims. This paper lays the groundwork for an empirical analysis of the question of how far SD can be achieved through SRM. It describes the so-called SD–SRM perspective as a distinctive research approach and shows how it relates to the wider body of stakeholder theory. Next, the concept of SD is operationalized for the microeconomic level with reference to important documents. Based on the ensuing SD framework, it is shown how SD and SRM relate to each other, and how the two concepts relate to other popular concepts such as Corporate Sustainability and Corporate Social Responsibility. The paper concludes that the significance of societal guiding models such as SD and of management approaches like CSR is strongly dependent on their footing in society.

This paper re-examines the link between new firm formation and subsequent employment growth. It investigates whether it is possible to have the wrong type of entrepreneurship—defined as new firm formation which leads to zero or even negative subsequent employment growth. It uses a very similar approach to that of Fritsch and Mueller (Regional Studies, 38(8), 961–976, 2004), confirming their findings that the employment impact of new firm formation is in three discrete phases. Then, using data for Great Britain, the paper shows the employment impact of new firm formation is significantly positive in the high-enterprise counties of Great Britain. However, for the low-enterprise counties, it shows that new firm formation has a negative effect on employment. Of the 15 low-enterprise regions, eight are Scottish (of nine Scottish regions in our data base) and three are North East Counties (of four). Our findings imply that having the “wrong type of entrepreneurship” is indeed possible.

Research shows that, under certain circumstances, people using GSS can be substantially more productive than people who do not. However GSS has been slow to transition into the workplace. This paper argues that the Technology Transition Model (TTM) may be a useful way to explain this seeming paradox. The paper presents a case study of GSS transition in two organizations – one where a self-sustaining and growing community of users emerged, and one where it did not. Following TTM, it explores the frequency with which users perceived cognitive, economic, affective, political, social, and physical value from using the system. Comparison of the cases reveals differences in perceptions of value along several of these dimensions that are consistent with TTM. The findings suggest the model may be a useful way to explain the transition of collaboration technology, but more research will be required to test the model more rigorously.  相似文献

Based on a theoretical exploration in a previous article, this paper empirically analyzes which issues of SD are taken into account by corporations and stakeholders in what way, and to what extent the concept of sustainable development (SD) can be achieved through stakeholder relations management (SRM) on the corporate level. An important basis for this empirical analysis is a referential framework, which specifies 14 issues of SD. In a first empirical step, the literature-based framework has been operationalized for the business world by analyzing sustainability reports. In a second empirical step, the operationalized framework served as the basis for a survey of selected MNCs. The analyses of the sustainability reports and the survey show how MNCs deal with particular issues of SD and what role they perceive particular stakeholders play. A key conclusion of the article is that SRM indeed promotes SD, but that it is no alternative to predictable government regulation.  相似文献
