We offer empirical information on the correlates of commercialization activity for research projects funded through the US National Institutes of Health's (NIH's) Small Business Innovation Research (SBIR) award program. Based on this analysis we suggest possible recommendations for improving this aspect of the performance of NIH's SBIR program. Specifically, we estimate a model of the probability of commercialization as a function of the project's ability to attract additional developmental funding, along with other control variables. We find that additional developmental funding from non-SBIR federal sources and from own internal sources are important predictors of commercialization success, relatively more so than additional developmental funding from venture capitalists. We also find, among other things, that university involvement in the underlying research increases the probability of commercialization. Thus, these factors should be considered by NIH when making awards, if increased commercialization is an objective.  相似文献

Abstract

This article draws on the conflicting arguments surrounding outdoor adventure tourism activities to determine if such activities might usefully be considered beneficial for humans and nature, and how they might offer avenues for sustainable tourism practice. Research in the field has often examined outdoor adventure activities through a lens that either highlights their negative environmental impacts or has sought to conceptualise motivations and/or experiences. In this article, we argue that through practices that are often seen as destructive, there is the possibility to think differently about human-nature relationships and pro-environmentalism. To explore these issues, we draw on data collected from a series of semi-structured interviews with outdoor adventure tourists. Our analysis highlights how outdoor adventure tourism facilitates reconnections to nature, offering potential wellbeing impacts and pro-environmental attitudes and behaviours. We conclude that outdoor adventure activities as a form of sustainable tourism have potential implications for our understanding of, and engagement with, sustainability, mental health and wellbeing.  相似文献

The institutional environment of science differs across countries. Its particularities have an impact on productivity of scientific enterprise in terms of both research and teaching. Reform of the system of higher education occupies an important place in programs of catch-up modernization. Attempts to replicate Western institutional arrangements and organizational designs in this area have been undertaken in Russia since the very beginning of economic and political reforms of the 1990s. This paper considers a particular transplant, the Higher School of Economics (HSE) established in 1992, and its subsequent evolution. A structural analysis shows its divergence from the organizational patterns that served as a model. The HSE case is compared with several "representative" Western universities as well as other Russian universities. When explaining divergent patterns between the HSE and the Western counterparts, special attention is paid to the issue of power relationships and their role in the functioning of the scientific organization. The paper aims to contribute to the discussion of "cultural entrepreneurs" and their motivation.  相似文献

This paper explores the concept of internal marketing (IM) as an internal supportive system that could provide the infrastructure for a strategic business take-off. It investigates how IM, as a concept, is understood and made practical in the context of Ghanaian small- and medium-sized enterprises (SMEs). This qualitative research method was used due to the nature of the enquiry. The government of Ghana is constantly searching for more effective ways of assisting SME performance, through various strategic growth and development schemes. Despite the fact that much has been said in the literature, the IM concept remains elusive. Most SMEs are not aware of IM and demonstrate little understanding of the concept. And SMEs have problems with the implementation of IM. The manufacturing sector demonstrates more IM orientation than does the service sector. This paper unravels sociocultural factors that frustrate the practice of IM among Ghanaian SMEs and calls for a greater awareness of the concept by stakeholders. Suggestions include more general business support for SMEs to improve performance and subsequently grow. The paper finishes by drawing attention to management implications within the practice of IM.  相似文献

In the context of green bonds playing an increasingly vital role in the green financial market, this study selects 61 green bonds issued in China from 2016 to 2021 as samples to examine the factors influencing green bond credit, including financial information and ratings of issuers, green certification, and government subsidies. First and foremost, based on AHP and entropy method, the financial composite index is constructed to evaluate the issuers’ finance. Additionally, the differences in the cost of green bonds issued by state-owned enterprises (SOEs) and semi-enterprises are explored by adding the property rights variable. Empirical results indicate that the issuer’s rating could significantly affect the credit spread. In addition, the green bond credit spreads of SOEs are more competitive than those of semi-enterprises. When the issuer is a SOE, green bond credit spread has a remarkable negative correlation with finance information. Furthermore, green certification and government grants are not the main factors. Finally, the green bond market, crucial to controlling the green financial system, is presented with specific recommendations for its growth in this study.

This article will show the impact of employment equity legislation on the psychological employment contracts of the three main employee groupings in South African society. This study is important in that it fills the gap in the literature that identifies labour market regulations as an important shaping influence on the psychological contract. More than 500 managers from across South African industry and from all ethnic groups were surveyed to identify differences in psychological contracts and attitudes towards the social transformation regulations. We found that the legislation has impacted differentially on the three groupings mainly in terms of their loyalty to stay with their organizations, the focus on their career development in terms of the external labour market and the degree to which they felt they had been affected by the legislation. Additionally we find that the perceived linkage between job satisfaction and labour turnover is significantly weakened by labour market legislation in the case of the beneficiaries of the legislation, but that this may not be the case for those negatively affected by the legislation. The findings have significant implications for the HRM practices of multinationals operating in societies with significant labour market regulatory interventions.  相似文献

Extant research on the decomposition of unit sales bumps due to price promotions considers these effects only within a single product category. This article introduces a framework that accommodates specific cross-category effects. Empirical results based on daily data measured at the item/SKU level show that the effects of promotions on sales in other categories are modest. Between-category complementary effects (20%) are, on average, substantially larger than between-category substitution effects (11%). Hence, a promotion of an item has an average net spin-off effect of (20 − 11 =) 9% of its own effect. The number of significant cross-category effects is low, which means that we expect that, most of the time, it is sufficient to look at within-category effects only. We also find within-category complementary effects, which implies that competitive items within the category may benefit from a promotion. We find small stockpiling effects (6%), modest cross-item effects (22%), and substantial category-expansion effects (72%). The cross-item effects are the result of cross-item substitution effects within the category (26%) and within-category complementary effects (4%). Approximately 15% (= 11% / 72%) of the category-expansion effect is due to between-category substitution effects of dependent categories.  相似文献

Most research on corporate directors has focused on two roles: agency and resource dependence. While these two roles are theoretically and practically distinct, previous research has used the same classification scheme for measuring board composition regardless of role examined. Our paper examines the resource dependence role of directors and posits that the widely used insider/outsider categorizations do not adequately capture this role of directors. A taxonomy of directors is presented specifically for studying the resource dependence role. We then apply the taxonomy to a sample of US airline firms undergoing deregulation, and examine how board composition changes parallel the changing resource dependence needs of the firms. We conclude that the board's function as a link to the external environment is an important one, and that firms respond to significant changes in their external environment by altering board composition.  相似文献

Research summary : We develop and test a contingency theory of the influence of top management team (TMT) performance‐contingent incentives on manager–shareholder interest alignment. Our results support our theory by showing that although TMTs engage in significantly higher levels of acquisition investment when their average incentive levels increase, investors' responses to those large investments are generally negative. More importantly, however, we further find that within‐TMT incentive heterogeneity conditions that effect, such that investors evaluate TMTs' large acquisition investments more positively as the variance in those top managers' incentive values increases. Thus, within‐TMT incentive heterogeneity appears to increase manager–shareholder interest alignment, in the context of large acquisition investments. Managerial summary : We find that as the average value of TMTs' incentives increase, relative to their total pay, they invest more in acquisitions and investors' respond negatively to the announcement of those deals. However, we further show that investors respond more positively to acquisitions announced by TMTs whose members' incentive values vary (some TMT members hold higher incentives and others hold lower). Results imply that when TMT members hold differing incentives levels, they approach investments from divergent perspectives, scrutinize those investments more heavily, and make better decisions, relative to TMTs with similar incentives. They also suggest that boards seeking tighter manager–shareholder interest alignment may benefit from introducing variance into TMT members' incentive structures, as doing so appears to create divergent preferences that can improve team decision making.
