Developing the “Science of Science Policy” will require data collection and analysis related to the processes of innovation and technological change, and the effects of government policy on those processes. There has been much work on these topics in the last three decades, but there remain difficult problems of finding proxies for subtle concepts, endogeneity, distinguishing private and social returns, untangling cumulative effects, measuring the impact of government programs in a true “but for” sense, and sorting out national and global effects. I offer observations on how to think about these issues. This paper was presented as the Keynote Address at the NSF Workshop on Advancing Measures of Innovation: Knowledge Flows, Business Metrics, and Measurement Strategies, Arlington, VA, June 2006.  相似文献

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR® SGM Plus® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h.  相似文献

Government policies like the Advanced Technology Program (“ATP”) are intended, at least in part, to remedy the “market failure” inherent in the fact that a significant portion of the social benefits of new knowledge and technology are not captured by a firm that invests in R&D. ATP’s project selection, and its evaluation of the impact of its program, can be made more effective by explicitly incorporating the analysis of such “spillovers.” For project selection, this means identifying technological, organizational and economic factors that tend to oint to a large “spillover gap,” or deviation between the social and private rates of return to a proposed project. For program evaluation and assessment, it means adapting existing study methods that measure social returns to innovation in ways that explicitly capture spillover effects. This paper is based on a study that I performed for the ATP, Economic Analysis of Research Spillovers: Implications for the Advanced Technology Program, NIST GCR 97-708. I have benefited from comments and useful discussions with Zvi Griliches, Jeanne Powell, Rosalie Ruegg, and Richard Spivack. Some of the ideas in this paper grew out of previous joint research with James Adams. The views expressed herein are my own, however, and should not be attributed to any of these individuals or to the ATP.  相似文献

This article examines the recruiting practices, political propositions and changing identities of the Scottish adventurer Gregor MacGregor in the early nineteenth‐century Caribbean. Based on original archival research and revision of the existing secondary literature, it seeks to understand why he has consistently been judged as a failure, and why neither Scotland nor any of the countries MacGregor worked in have wanted to claim him as their own hero. After an introduction providing biographical details and some historical context for the Caribbean in the period 1811–1830, the article looks in detail at what have been seen to be his successes and failures in the Caribbean region. It asks to what extent questions of ethnicity or masculinity have affected the way contemporaries and historians viewed MacGregor and his actions. In conclusion, it suggests that although he was a soldier and a sailor, and he was declared both an Inca and a King, his career was deemed a failure by both contemporaries and historians in Scotland, South America and the Caribbean. The main explanation for this negative assessment is that his ambitions continually fell foul of the interests of various Caribbean elites and of the distinctive historical circumstances of the region.1  相似文献
