Entrepreneurship as a scientific field has grown significantly, irrespective of the measures used. In this article we raise the question: How can we understand the evolution and success of entrepreneurship as a scholarly field? In particular, we focus on the social structure of entrepreneurship scholars to explain (1) how they are becoming integrated into larger scholarly communities and (2) how they differ from the way scholars integrate within the field of innovation studies. Based on a unique database and responses from 870 entrepreneurship scholars, we demonstrate that entrepreneurship can be regarded as a phenomenon-driven field bound together by a shared communication system and social interaction rather than strong theoretical influences, i.e., a social scholarly community. We identify two broader social communities; one embedded in entrepreneurship conferences that includes a rather eclectic group of entrepreneurship scholars, and another related to entrepreneurship journals and entrepreneurship economics, characterized by a stronger domain orientation. In contrast, scholars in innovation studies tend to be more theory-driven and are bound together by their disciplinary and theoretical background, i.e., an intellectual scholarly community.  相似文献

While the female activewear market is growing rapidly, research on activewear consumption and female consumers is lagging. Existing researchers have failed to produce an in-depth understanding of female consumers’ perceptions of activewear, thereby providing limited insights for the activewear industry. Drawing upon brand association theory and the functional, expressive, and aesthetic model, the authors identify important attributes of activewear brands and how attributes lead to benefits pursued by female activewear consumers. Focus groups were conducted with 72 female activewear consumers in Australia. Findings reveal three product-related attributes (functional design, colour, and size and fit) and two non-product-related attributes (price and model imagery) influence the fulfillment of four benefits (mood enhancement, exercise facilitation, healthy and active lifestyle, and physical fit body image). This research contributes theoretical and empirical knowledge about activewear consumption and the vertical structure of brand associations. Findings of this research can help activewear brands deliver benefits to female consumers through improved product designs and marketing strategies.  相似文献

Abstract

The assessment of nutrition and activity in athletes requires accurate and precise methods. The aim of this study was to validate a protocol for parallel assessment of diet and exercise against doubly labelled water, 24-h urea excretion, and respiratory gas exchange. The participants were 14 male triathletes under normal training conditions. Energy intake and doubly labelled water were weakly associated with each other (r = 0.69, standard error of estimate [SEE] = 304 kcal · day?1). Protein intake was strongly correlated with 24-h urea (r = 0.89) but showed considerable individual variation (SEE = 0.34 g · kg?1 · day?1). Total energy expenditure based on recorded activities was highly correlated with doubly labelled water (r = 0.95, SEE = 195 kcal · day?1) but was proportionally biased. During running and cycling, estimated exercise energy expenditure was highly correlated with gas exchange (running: r = 0.89, SEE = 1.6 kcal · min?1; cycling: r = 0.95, SEE = 1.4 kcal · min?1). High exercise energy expenditure was slightly underestimated during running. For nutrition data, variations appear too large for precise measurements in individual athletes, which is a common problem of dietary assessment methods. Despite the high correlations of total energy expenditure and exercise energy expenditure with reference methods, a correction for systematic errors is necessary for the valid estimation of energetic requirements in individual athletes.  相似文献

Political theorists like Alexis de Tocqueville have long recognized the importance of citizen associations for the practice of democracy. Through participation in associations, citizens both receive an education in public affairs and create centers of political power independent of the state. Essential to participation in an association is participation in a forum, a communication space that allows for many-to-many communication in which citizens can "treat of public affairs in public" (Tocqueville, 1945, p. 109). Participation in forums suffers from numerous barriers, however, such as the need to meet in one common place, the need to meet at one common time, and the potentially high costs of participation. Online forums on the Internet avoid many of these barriers, and thus they hold the promise of facilitating the formation and operation of citizen associations. This was confirmed in 1995 by the experiences of a Boston-based citizen association, the Telecommunication Policy Roundtable-Northeast (TPR-NE). TPR-NE's uses of the Internet suggest that online forums may allow associations to be more responsive, more robust, and able to unite more members.  相似文献

This paper represents the views of two scholars in the USA with respect to the scholar lecture presented by David Kirk at the 2012 BERA – Physical Education and Sport Pedagogy (PESP) Special Interest Group meeting. We discuss how two unique features of the American universities have an impact on both the corporate nature of our work and our scholarship. These features are described as ‘the notion of outreach scholarship’ and the ‘nature of giving.’ In addition, we discuss our different situations and how they affect our ability to do the best academic work. We can, and by consequence, give our best efforts to resist the hegemony of corporatization.  相似文献
