US State governments invest in early-stage innovative activity as an economic development strategy. Nevertheless, attention directed at the public sector’s role in this capacity has been placed on federal policy actions overlooking the growing role of states. The primary aims of this paper are two-fold: (1) to articulate the motivations for multilevel public support for small business innovative activity, placing emphasis on state level incentives directed towards entrepreneurial activity; and (2) to empirically evaluate the State Match Phase I (SMP-I) program. The SMP-I program is a diffuse state level policy designed to complement the federal Small Business Innovation Research (SBIR) program by offering noncompetitive matching funds to the state’s successful SBIR Phase I recipients. This offers an opportunity to examine the marginal impact of public R&D given the state intervention. This paper employs a state and year fixed effects model and considers two outcome variables—SBIR Phase II success rates and SBIR Phase I application activity. To account for industrial heterogeneity, the data are stratified by the federal mission agencies. Results from the empirical analysis indicate that the state match increases the Phase II success rates for firms participating in the National Science Foundation SBIR program. 相似文献

A major challenge to the Doctrine of Double Effect (DDE) is the concern that an agent’s intention can be identified in such a fine-grained way as to eliminate an intention to harm from a putative example of an intended harm, and yet, the resulting case appears to be a case of impermissibility. This is the so-called “closeness problem.” Many people believe that one can address the closeness problem by adopting Warren Quinn’s version of the DDE, call it DDE*, which distinguishes between harmful direct agency and harmful indirect agency. In this paper, I first argue that Quinn’s DDE* is just as vulnerable to the closeness problem as the DDE is. Second, some might think that what we should therefore do is give up on intentions altogether and move towards some kind of non-state-of-mind, victim-based deontology. I shall argue against this move and explain why intentions are indispensable to an adequate nonconsequentialist theory. Finally, I shall propose a new way of answering the closeness problem. 相似文献

How should the judge or jury in a just criminal court treat a civil disobedient, someone who performs a conscientiously motivated communicative breach of the criminal law? Kimberley Brownlee contends that all else equal a court of law should neither convict nor punish such offenders. Though I agree with this conclusion, I contend that Brownlee mischaracterizes the nature of the criminal defense to which civil disobedients are entitled. Whereas Brownlee maintains that such actors ought to be excused for their criminal breach, I argue that they ought to enjoy a justification defense. Acts of civil disobedience are not (morally) wrongful violations of the law for which an actor ought not to be blamed; rather, they are violations of the law that are not (morally) wrong in virtue of their illegality. It is the absence of wrongdoing, and not merely the absence of fault, that renders the conviction and punishment of those who perform acts of civil disobedience inappropriate. 相似文献
