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

Abstract:  With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element concentrations was investigated. Paper samples from two different vendors were microwave-digested and trace element concentrations (Mg, Al, Mn, Fe, Sr, Y, Ba, Ce, and Nd) were determined using inductively coupled plasma–mass spectrometry. Differences in concentration were assessed statistically using two-way ANOVA and Tukey's honestly significant differences test. Elemental concentrations were shown to be consistent across a single sheet as well as within a single ream of paper for each vendor. Reams from vendor A were differentiated based on Al and Ba concentration while reams from vendor B were differentiated based on Mg, Mn, and Sr concentrations. Paper was differentiated according to vendor based on significant differences in Ba, Sr, Ce, and Nd concentrations.  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 current controversy over the politicization of science by the Bush administration is, by definition, a political controversy. As such, it must be addressed by political measures as well as the administrative strategies that Dr. Lambright suggests. The administration's actions go beyond the bounds of "business as usual" and reflect the interests of its powerful constituencies, as well as the unease of many citizens with some scientific and technological advances. Scientists need to engage these citizens and take their concerns into account in order to build trust between the scientific community and the public, as well as to impede unscrupulous politicians from distorting scientific information to suit their purposes.  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
