The transitions literature emphasises the role of niches, defined as a protective space for path-breaking innovations. Surprisingly, the concept of protection has not been systematically interrogated. Our analysis identifies effective protection as having three properties in wider transition processes: shielding, nurturing and empowerment. Empowerment is considered the least developed in current niche literature. It can be understood as either processes that make niche innovations competitive within unchanged selection environments (fit-and-conform) or as processes that contribute to changes in mainstream selection environments in ways favourable to a path-breaking niche innovation (stretch-and-transform). Adopting a more constructivist perspective, we subsequently argue that analysis of these properties needs to be complemented with particular attention for the politics involved in their construction. Attention to empowerment confirms the view that niche actors need to link to wider processes of social change, and suggests how this arises. The paper ends with an outlook upon two promising research avenues: (1) the reconstruction of niche development in light of the present framework; (2) analyses of the diverse (political) narratives seeking to empower niches across time and space. 相似文献

This paper investigates different types of innovations (from radical to incremental) in the pharmaceutical industry by studying bibliometric data of drugs approved by the United States Food and Drug Administration (FDA), looking at time-to-market aspects, knowledge sources of these innovations, and protection strategies. Scientific knowledge stemming from the public sector is found to be important for all innovations. Nevertheless, radical innovations build on a higher degree on basic research, and they build on a significantly higher share of own prior scientific research than do incremental innovations. Furthermore, each drug is shown to be accompanied by, on average, about 19 journal publications and 23 additional patents. Additional patent filings peak when the commercialization of the drug is in reach. Firms do not differ among the various types of innovations regarding the amount of additional patent filings, but rather with the speed of filing these patents. Finally, this work contributes to the improvement of future econometric analyses that aim to link bibliometric indicators such as patent or publication counts to firm success. 相似文献

Advances in the publishing world have emerged new models of digital library development. Open access publishing modes are expanding their presence and realize the digital library idea in various means. While user-centered evaluation of digital libraries has drawn considerable attention during the last years, these systems are currently viewed from the publishing, economic and scientometric perspectives. The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive. The results demonstrate that several attributes of usefulness, such as the level and the relevance of information, and usability, such as easiness of use and learnability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction. 相似文献
