In 1982, the Small Business Innovation Development Act established the small business innovation research (SBIR) program. This program reserves a percentage of federal agencies’ extramural R&D budgets for research projects conducted by small businesses. When this Act was reauthorized in 1992, the selection criteria for funding dramatically increased the likelihood of funding for projects that promised to lead to commercial success. Using data from a survey of the SBIR program award recipients at NASA Langley Research Center, we address three questions about this change: (i) was there a shift to projects with more commercial potential? (ii) did these projects experience higher rates of commercial success? and (iii) was there a reduction in basic research accompanying the increased commercial success? Our analysis suggests, the answer to all three of these questions is ‘yes’.  相似文献

The purpose of this paper is to examine whether the technical universities have been more successful in facilitating the spillover and commercialization of knowledge. We compare the impact of technical and general universities on the performance of knowledge-based firms. Based on a unique data set consisting of publicly held high technology firms, the empirical evidence suggests that, in fact, firm performance is not influenced by the type of university. Technical universities do not have a differential impact on firm performance from more general universities.  相似文献

The relationship between institutional change and entrepreneurship is poorly understood. We build the theory in this area by tracing institutional change in the US electric power industry over a 40-year period. Our analysis shows that environmental jolts mobilize actors to reformulate institutions, resulting in increased entrepreneurial opportunity. When the institutional environment is stable, we find that incumbent organizational forms and embedded logics present formidable obstacles to entrepreneurial activity. Environmental jolts, however, catalyze search processes and motivate the evaluation of current institutional logics. Specifically, in the case of the electric power industry, environments of abundance and regulation resulted in homogeneity of organizational structures and strategies, and few entrepreneurial opportunities. Environments marked by scarcity and crisis, however, witnessed heavy scrutiny of existing institutional arrangements that eroded their taken-for-grantedness and symbolic value, resulting in opportunities for entrepreneurial action.  相似文献

Case histories were compiled of 100 instances of technological change in 102 manufacturing companies in eight industries in Ireland, Spain and Mexico. The cases are analyzed for the source of initial ideas and for sources of technology employed in resolving major problems.Technology is found to flow principally through informal channels within industries. Very little information was obtained from the formal mechanisms or institutions normally considered central to the technology transfer process.Foreign subsidiaries obtain the greatest proportion of their technology from their parent firms. Surprisingly, they are found to have several channels of technology blocked to them, which are more readily available to domestic firms. Domestic firms, in many ways have easier access to foreign technology than do the subsidiaries of multinational firms.Product and process innovations originate in somewhat different quarters. Process innovations are slightly more likely to be based on foreign technology; product innovations are more likely to be based on domestic technology.The results reported in the present paper are very similar in many ways to results reported previously in Brazil and Australia.  相似文献

The work practices of the professional photojournalist are currently undergoing rapid change in the digital era. New technologies, new platforms and new methods of visual storytelling are exerting a range of pressures and influences that require photojournalists to adapt and respond in different ways. The changes provoke a number of questions that are critical to the future of professional photojournalism: What are the new risks being faced by photojournalists? How are the transformations in the media economy affecting photojournalists’ employment? What does this mean for image quality? How do photojournalists think about the manipulation of images or the staging of events? Given the rise of citizen journalism, digital technology and social media, will there even be professional photojournalists in the future? This paper presents some of the results and new analysis from the first international study into the current state and future of professional photojournalism, with a specific focus on risk and on perceptions of risk among photographers. The results indicate a high degree of risk is experienced among professional photographers with a very strong correlation to the country in which they are based.  相似文献

ABSTRACT

A case study demonstrating how an online narrative featuring the adventures of a cuddly toy penguin, Pablo Penguin (@uoppenguin on Twitter) has been introduced at the University of Portsmouth Library to build trust and engagement between university students and library services and facilities. Evidence for the benefits of anthropomorphic brand mascots and best practice for their design and use to enhance the library brand, emotionally engage, build trust, lower barriers to service engagement, and mentor students from the perspective of a perpetual student are drawn from the marketing and psychological literature then illustrated in the case study.  相似文献

1我沿着一条小路穿过乔治亚州的一片森林,看到这条小路的前面有一个水坑。我改变方向,从这条小路没有水和泥浆的地方绕过这个水坑。当我走到水坑边时,突然受到了攻击!但是,对这根本无法预测、完全不知从何处而来的攻击,我毫无防备。我吃了一惊,尽管已经受到了四五次攻击,但没存受伤。我后腿了一步,攻击者停止了攻击。他拍动着美丽的蝴蝶翅膀盘旋在我面前的空中。如果我受了伤,我就不会发现这是多么有趣,但是,我没有受伤,我大笑了起来。毕竟,攻击我的不过是一只蝴蝶!  相似文献
