Entrepreneurship: Exploring the knowledge base 总被引:1,自引:0,他引:1
Entrepreneurship research has a long tradition and since the 1980s the field has grown significantly. In this study we identify the ‘knowledge producers’ who have shaped the field over time and their core entrepreneurship research works. A unique database consisting of all references in twelve entrepreneurship ‘handbooks’ (or state-of-the-art books) has been developed. The chapters in these handbooks were written by experts within the field, and it can be assumed that the most frequently cited references represent ‘core knowledge’ with relevance to entrepreneurship research.From our analysis, it appears that entrepreneurship is a rather changeable field of research, closely linked to disciplines such as ‘management studies’ and ‘economics’. Over time, the field has become more formalized with its own core knowledge, research specialities and an increasing number of ‘insider works’. However, it is still based on some fairly old theoretical frameworks imported from mainstream disciplines, although during the last decade we have seen the emergence of a number of new field-specific concepts and theories. We argue that to successfully develop entrepreneurship research in the future, we need to relate new research opportunities to earlier knowledge within the field, which calls for a stronger ‘knowledge-based’ focus. We would also like to see greater integration between the fields of entrepreneurship and innovation studies in the future. 相似文献

Sustainability oriented innovation and technology studies have received increasing attention over the past 10-15 years. In particular, a new field dealing with “sustainability transitions” has gained ground and reached an output of 60-100 academic papers per year. In this article, we aim to identify the intellectual contours of this emerging field by conducting a review of basic conceptual frameworks, together with bibliographical analysis of 540 journal articles in the field. It is against this background that we position the six papers assembled in a special section in Research Policy. These papers pave the way for new conceptual developments and serve as stepping-stones in the maturation of sustainability transition studies, by linking with the scholarly literatures of management studies, sociology, policy studies, economic geography, and modeling. 相似文献

This paper addresses the challenge of striking a balance between, on one hand, mitigating uncertainty through the existence of systematic processes and structures and, on the other, stimulating creativity through allowable variation in work processes and structures. Both objectives are fundamental aspects of product development work. Our main finding is that both objectives can be achieved simultaneously. We introduce trust as a mediating variable. We show first, that being systematic in the processes for obtaining information and applying explicit organizational rules and structures in product development work creates an atmosphere of trust in the organization. Second, we show that trust increases creativity. The paper contributes to an understanding of how and why trust is important in product development organizations and of how trust can be actively managed. Above all, the paper contributes to the understanding of how uncertainty and creativity should be managed in organizations conducting product development. 相似文献

Wrist injuries are frequently observed after falls in snowboarding. In this study, laboratory experiments mimicking forward and backward falls were analysed. In six different falling scenarios, participants self-initiated falls from a static initial position. Eighteen volunteers conducted a total of 741 trials. Measurements were taken for basic parameters describing the kinematics as well as the biomechanical loading during impact, such as impact force, impact acceleration, and velocity. The effective mass affecting the wrist in a fall also was determined. The elbow angle at impact showed a more extended arm in backward falls compared to forward falls, whereas the wrist angle at impact remained similar in forward and backward falls. The study results suggest a new performance standard for wrist guards, indicating the following parameters to characterize an impact: an effective mass acting on one wrist of 3-5 kg, an impact angle of 75 degrees of the forearm relative to the ground, and an impact velocity of 3 m/s. 相似文献

BACKGROUND: Information technology (IT) has slowly been implemented in many health-care organizations (i.e. hospitals). The use of computers has advanced to home care and long-term facilities. Consequently, it is important that nurses are able to demonstrate competence and feel confident in the use of IT. Yet, research has reported that nursing students have varying degrees of competence and experience with IT. AIMS: The purpose of this study was to ascertain nursing students' and nursing educators' self-reported attitudes, skills and experiences using IT. METHODS: Data were collected through a written survey distributed and completed by 247 nursing students (45 of whom were registered nurses who participated in extension courses) and 52 staff members from the nursing faculty at a university in Sweden. RESULTS: Two-thirds of the students and 92% of the nursing educators had access to the Internet from their homes. Of the students, 71% identified their IT skills as being sufficient for their current or future work as a registered nurse. Nurse educators were less confident in the students' ability, reporting that only 29% of nursing students had sufficient IT skills. Comparatively, 48% of the nursing educators believed that they themselves had sufficient IT skills for their role as a nurse educator. CONCLUSIONS: It is important that nursing students have basic IT skills and are familiar with e-mail, word-processing and various databases on the World Wide Web. Findings indicate that participants had a deficit in these skills, suggesting the need to integrate IT into the nursing curriculum. 相似文献
