Thinking of government as entrepreneur is a unique lens through which to view a subset of government actions. The lens is not a template for an evaluation of government policy; rather, it is a characterization that underscores the government's purposeful intent, ability to act in new and innovative ways, and willingness to undertake policy actions that have uncertain outcomes. Our focus is on the U.S. Small Business Innovation Research (SBIR) program. We argue that the innovative action of government - the innovative use of public resources through the SBIR program to target and support research in small firms - does lessen innovation barriers that cause small firms to underinvest in R&D. However, this government action is subject to entrepreneurial risk, namely the a priori uncertainty that the funded research will result in a commercialized product, process, or service. We quantify the uncertainty that the government accepts in the context of innovation supported by the SBIR program; or stated alternatively, we quantify the probability that a project funded by the SBIR program will fail to commercialize its results. Our empirical results show that the entrepreneurial risk that characterizes the SBIR program is, on average, somewhat more than the probability of failing to get heads on the toss of a fair coin. Importantly, however, our evidence shows that there is a large range in the entrepreneurial risk that the government accepts—across the projects, the predicted probability of failure covers essentially the entire range from 0 to 1.0. 相似文献

Strategic research partnerships (SRPs) have become a salient feature of the US National Innovation System. We provide an overview of SRPs and examine the antecedents and consequences of centerpiece legislation designed to stimulate the formation of SRPs: the National Cooperative Research Act (NCRA) of 1984. NCRA allows firms to disclose their research joint ventures (RJVs) to the Department of Justice, which enabled them to significantly reduce their exposure to antitrust litigation. We estimate an econometric model of trends in RJV filings and find that, as intended by the legislation, the propensity of firms to engage in RJVs is sensitive to changes in the global competitiveness of US high-technology industries. More importantly, our results suggest that the establishment of the Commerce Department’s Advanced Technology Program, which provides financial support to firms that engage in collaborative research projects, induced firms to engage in additional (privately financed) RJVs. This is a spillover mechanism that warrants further attention as national innovation systems evolve. 相似文献

Entrepreneurship involves innovation and uncertainty. We outline a theory of entrepreneurship, which highlights the importance of social networks in promoting innovation and reducing uncertainty. Our findings suggest that this “social” aspect of entrepreneurship increases the probability of entrepreneurial success. The results also lend credence to theories of entrepreneurship that suggest that entrepreneurial opportunities are formed endogenously by the entrepreneurs who create them. We also consider the public policy implications of our findings. 相似文献

Many previous time allocation studies treat work as a single activity and examine trade-offs between work and other activities. This paper investigates the at-work allocation of time among teaching, research, grant writing and service by science and engineering faculty at top US research universities. We focus on the relationship between tenure (and promotion) and time allocation, and we find that tenure and promotion do affect the allocation of time. The specific trade-offs are related to particular career paths. For example, full professors spend increasing time on service at the expense of teaching and research while longer-term associate professors who have not been promoted to full professor spend significantly more time teaching at the expense of research time. Finally, our results suggest that women, on average, allocate more hours to university service and less time to research than do men. 相似文献

US school libraries are required to ensure that schoolchildren and school staff with disabilities have equal opportunity to use and benefit from library facilities and information services under federal law. However, evidence indicates teacher‐librarians (TLs) often lack the training, knowledge and skills to provide programmes and services that meet the needs of students with disabilities. Project ENABLE (Expanding Nondiscriminatory Access by Librarians Everywhere) was created to respond to this shortfall by designing, implementing and evaluating a professional development programme in New York State. The project applies a social model of disability to help 100 TLs, special educators and general educators further develop their skills and resources by teaming together to create an inclusive environment for all students. This is achieved through the use of universal design principles, appropriate assistive and other technologies, an emphasis on person‐first language and sensitivity simulations, a focus on inclusive lesson planning, and by developing collaboration capacity among participant teams. Curriculum development, data collection and analyses are presented. The effect of the Project ENABLE trainings was significant in terms of higher levels of skill and knowledge reported by participants for creating accessible library programmes, advancing inclusive education and building effective collaborations. Drawing from their workshop learning and resources, participant teams developed action plans to implement during the 2011–2012 school year. This project underscores the importance of TLs in the education of all students, including those with disabilities. Higher education and local professional development programmes must place greater emphasis on preparing TLs to perform this role effectively and confidently. 相似文献

This article discusses and demonstrates combining scores from multiple-choice (MC) and constructed-response (CR) items to create a common scale using item response theory methodology. Two specific issues addressed are (a) whether MC and CR items can be calibrated together and (b) whether simultaneous calibration of the two item types leads to loss of information. Procedures are discussed and empirical results are provided using a set of tests in the areas of reading, language, mathematics, and science in three grades. 相似文献
