In this paper we compare the relationship between a firm’s innovation capital and the likelihood that a firm will commercialize an invention. Our index of innovation capital is the product of the firm’s human capital, social capital, and reputational capital. We find from our empirical experiment, which uses Small Business Innovation Research data, that innovation capital is a statistically more important entrepreneurial input to the innovation output of commercialization than any of its components.  相似文献

There are several accounts of the past relations between Swaziland and South Africa. Some are set in the realist school of international relations scholarship. These studies portray Swaziland's policy behaviour as ‘submissive’ because of ‘immutable structural forces’. The neo-Marxian analyses locate the relations exclusively in class/ideological setting. Other accounts depict the ‘kaleidoscopic’ nature of the relations. The post-apartheid understanding of this relationship is largely gleaned from regional studies – the dominant view of which is that South Africa is reluctant to exercise hegemony in its relations with regional states. This article critiques the one-directional thrust of the realist and Marxian accounts. While endorsing multidirectional and multidimensional accounts of policy behaviour, the article shows that they lack an over-arching theoretical framework. A similar charge is directed at the post-apartheid literature. The position of this article is that constructivism offers analytical tools needed to understand the relations between the two states and how South Africa can reorder them.  相似文献

Abstract

From a criminological perspective, romantic relationships are supposed to decrease the risk of antisocial behaviour (Laub, Nagin, & Sampson, American Sociological Review, 63, 225–238, 1998). However, the effects of these relationships probably depend on the romantic partner's behaviour. In the current study we examined partner similarity for antisocial behaviour in an ethnically heterogeneous community sample of 4135 married, cohabiting and dating couples from Rotterdam, the Netherlands, using self-reports. Spousal correlations were consistently positive for antisocial behaviour but differed in strength according to the type of antisocial behaviour. Associations between spouses remained strong after adjusting for age and educational level depending on the type of antisocial behaviour. In addition, antisocial behaviour was positively associated between partners across marital status and ethnicity, but the strength of this association varied to some extent. Results are discussed in light of the phenotypic assortment, the socialization and the social homogamy hypotheses.  相似文献

In this paper we show that the patenting behavior of innovators is correlated with the patenting behavior of their fathers. Our argument for exploring this relationship stems from established theories of entrepreneurial behavior, specifically theories on intergenerational behavior. Our empirical analyses are based on survey data collected from MIT’s Technology Review (TR) winners.  相似文献

During the 6th Conference of Parties (COP-6) in The Hague, the Netherlands, November 2000, crucial progress on a number of outstanding issues related to the Kyoto Protocol will have to be made to open the way for its early ratification, if not to save it from complete failure. Given the present lack of internal US political support for the Kyoto Protocol, the EU may play a pivotal role in making the Kyoto Protocol agreement a reality even without initial ratification of the US, if its able to provide sufficient leadership. In this overview article we discuss the main issues under negotiation, the problems of finding agreement and opportunities for the EU to catalyse a compromise agreement at COP-6, building on key scientific papers as included in this issue and discussions at the European Forum on Integrated Environmental Assessment Climate Policy Workshop in Amsterdam. Key elements are the inclusion of sinks, the use of the Kyoto Protocol mechanisms as a supplement to domestic action and the international compliance system. Domestic implementation of climate policy is a major factor for the EU's credibility.  相似文献

This paper describes a small, unique set of project data that was assembled as part of a larger study on universities as research partners. Herein, we summarize, to the extent possible, our interpretation of what the project data reveal about barriers, intellectual property (IP) concerns in particular, inhibiting industry from partnering with universities.  相似文献

The U.S. government has long included in its tax code various special provisions designed to stimulate industrial R&D. In 1981, those provisions were substantially augmented by a special R&D tax credit, and various proposals are now under consideration to relax the antitrust statutes in order to encourage research through joint ventures. The case for any of these measures is difficult to establish, being based on assumptions that are not readily tested in objective terms. Nevertheless, one point is fairly clear: As between stimulating industrial R&D by individual firms and stimulating R&D joint ventures of such firms, the joint venture approach appears superior in its likely results.  相似文献

This article looks at the effect that pretrial, statutorilyrequired screening panels in Nevada have had on medical malpracticelitigation. I use two unique data sets on litigation in Nevadaand neighboring states from 1983–88, during which theNevada legislature enacted screening panels. Applying time-seriesand difference-in-difference analyses, I show that observeddecreases in Nevada with respect to damage awards, attorney'sfees, and duration in litigation reflected a broader seculartrend. The panels did, however, reduce the relative probabilityof claims requiring resolution by the Nevada courts.  相似文献

Studies of criminal-court dispositions have traditionally aggregated courts along political and geographic boundaries. This article suggests that courts should be analyzed individually, even within the same jurisdiction, as a means of increasing the explanatory capacity of the variables involved. Further, it is contended that intercourt differences are a result of organizational influences operating within each court.  相似文献
