Chinese university patenting has gained importance in recent years. Using a comprehensive dataset of university patents by 155 leading Chinese universities from 1991 to 2009, our study pursues two objectives: First, we analyze the quantity and quality of patents filed by leading Chinese universities. Second, we analyze the role of subsidy programs with regard to university patenting in China. With regard to the first objective, our results show that university patents witnessed rapid growth in terms of quantity while patent quality did not increase to a similar degree. Regarding the second objective, we find that a subsidy program to promote research excellence at selected universities is a significant driver of patent quantity and quality. In contrast, a subsidy program that decreases the costs of patent applications seems to enhance patent quantity but not patent quality. We conclude that innovation policies which aim to stimulate patents of higher quality should focus primarily on increasing university R&D, and to a lesser extent on decreasing the costs of university patenting.  相似文献

The simple treatment of complex issues in the nuclear world has created dangerously self-deceptive and sterile views of such conflict. Calculations of missile duels and other possible strategic interactions have led to analytic self-deception where the more simplified the calculation, the greater the distance between the atrocious abstraction and the incomprehensible reality for which it serves as a disguise. Fictionalizing about deterrence and its variants has led to intellectual and moral self-deception where the focus of the fiction has diverted attention and action from other likely ways in which a nuclear conflict could be initiated, such as accidents, conventional wars, or terrorism. Besides reexamining old and diversionary patterns of thought and action—cultural strait jackets—we need more fundamental investigations into ways in which the weapons of modern war might be made less dangerous, procedures to make crises reversible, and improved and creative mechanisms for reducing and limiting the spread of nuclear weapons.  相似文献

This essay concentrates on the hitherto unknown origins ofIran-Contra. Through a series of interviews with participantsand access to previously private papers, the essay establishesthe role played by the U.S. and Israel in initiating arms deals with Iran before any hostage taking in Lebanon. Therefore,it corrects the proposition advanced by Special Prosecutor Walsh and others who linked the clandestine sale of weaponsto Iran with the deteriorating situation in Lebanon.  相似文献

In this note, a new method for defining gang activity areas based uponpolice records is illustrated using the Chicago Police Department's1996 incident files. This method is based upon standard geographictechniques and uses a uniform grid that divides the city into 150-msquares. It is shown that this technique may be useful both in describinggang activity areas and in describing the spatial distribution of crime inlarge cities. A strong relationship is found between the number of gangsthat are active in an area and the general level of criminal activity.  相似文献

Debt limits, interest coverage ratios, one‐off balanced budget requirements, pay‐as‐you‐go rules, and tax and expenditure limits are among the most important fiscal rules for constraining intertemporal transfers. There is considerable evidence that the least costly and most effective of such rules are those that focus directly on the rate of spending growth, even with their seemingly ad hoc nature and possibilities for circumvention. In this paper, we use optimal control theory and martingale methods to justify a transparent, nonarbitrary rule governing maximum sustainable rate of spending growth, treating the revenue structure of a jurisdiction as a given continuous‐time stochastic process. Our results can be used to determine whether a proposed rate of spending growth is sustainable or not. © 2009 by the Association for Public Policy Analysis and Management  相似文献

Covid-19 has highlighted our fragile relationship with the planet. But it represents a minor challenge compared to the permanent havoc that runaway climate change threatens. Politicians and governments—some at least—are beginning to recognise the scale of the danger. In this article we assess the evolution of policy thinking on how to make climate transitions happen; the potential of the European Green Deal; and how progressives need to shape it and any UK counterpart to meet the challenges of modern society. The European initiative arises from a broad coalition spanning the political spectrum. Yet, its central thrust of active government offers the prospect of reviving a battered social democracy. We indicate the openings here for a pluralist, ecological left. The run-up to the next global climate conference—COP26—will be a vital period which will show whether parties and governments across the world are prepared to meet the climate change challenge.  相似文献

Reparations whether to blacks for slavery, or to Indians for land theft, or to settle any number of other conflicts, has an interesting political background. Analysts on the left, who are usually no friend of private property rights, nevertheless rely on this doctrine to support their case for reparations. Those on the right, in contrast, who supposedly defend the institution of property rights, jettison them when it comes to reparations. It is only libertarians, such as the present authors, who both favor private property rights in general, and, also, apply them to the issue of reparations, who are logically consistent.

Despite interest in the role of religiosity in youth development and health behavior, few studies have examined these associations in sexual minority youth. Participants (n = 11,699) who were adolescents (wave 1) and young adults (wave 3) in the Add Health survey were used to examine proximal and distal religiosity by sexual identity group and to test group differences in associations between religiosity and alcohol use. Sexual minorities were less likely than heterosexuals to report a current religious affiliation. In young adulthood, heterosexual females reported significantly higher distal and proximal religiosity than heterosexual males and sexual minority young adults. From adolescence to young adulthood, religiosity in all three sexual identity groups (heterosexual, bisexual, gay/lesbian) significantly declined, with the largest effects found for the sexual minority groups. Distal and proximal religiosity scores were significantly associated with less alcohol use and less binge drinking among heterosexuals, but not among sexual minorities. Future studies of sexual minority youth and their religious contexts are suggested.
