The purpose of this study was to delineate the development of the Computerized Evaluation Protocol of Interactions in Physical Education, a data collection program for multiple interaction behavior measures in elementary inclusive physical education settings. The theoretical and empirical base for the Computerized Evaluation Protocol of Interactions in Physical Education is described in a three-phase study presenting (1) development of 25 multi-component interaction behavior items from presented literature, (2) content related evidence of validity evaluated by international adapted physical education experts, and (3) strong evidence of convergent validity of the Computerized Evaluation Protocol of Interactions in Physical Education. Overall, the outcomes of multiple studies indicated that the Computerized Evaluation Protocol of Interactions in Physical Education demonstrates promise for the adapted physical education research and assessment by documenting interaction behaviors in elementary physical education environments. 相似文献

This empirical study examines small firms’ strategies for capturing returns to investments in innovation. We find that small firms’ strategies are qualitatively different from those found in earlier studies of both small and large firms. Most of the small firms examined here find informal means of protection, such as speed to market or secrecy, more important than patenting. Only firms with university cooperation—typically R&D intensive and science-based small firms—were likely to identify patents as the most important method of appropriating innovation returns in their field. Thus, the strategic choice for most small firms is between secrecy and speed to market. Firms that cooperate in innovation with horizontal partners or significantly depend on vertical partners tend to prefer speed, whereas process innovators with modest R&D investments or few cooperative R&D activities display a preference for trade secrets. Indeed, cooperation activities greatly influence the choice of intellectual property strategy for small firms. Earlier research has emphasized patents and trade secrets as key strategies of appropriation, yet these strategies do not appear to be very beneficial for small firms engaged in cooperative innovation. These results raise policy questions regarding the functionality of the existing system of intellectual property rights. 相似文献

This empirical study analyzes the patterns of innovation within and across industries using firm-level survey data from Finland and Denmark. The theoretical starting point is evolutionary theory with its premise that firms in different technological regimes pursue different paths to innovation. Similar modes of behaviour are found in the two datasets, and they closely correspond to those found in earlier studies. Contrary to prevailing assumptions, however, the results show that industries are not at all uniform in terms of how firms innovate; in almost all four- or five-digit NACE industries, three or more different modes of innovation can be identified. This suggests that firms’ strategic differentiation or local search activities overcome pressures in the technological environment towards homogenous behaviour, at least in the short term. 相似文献

We examine patent licensing business models of non-practicing entities that generate revenue by selling, licensing, or litigating patents. They may also pursue R&D activities, invent new technologies, or provide services to inventors or product companies. We describe their business models and patent market behavior and then compare their litigation strategies against product companies using a matched sample of highly comparable patents. The main differences among patent licensing firms stem from their technological capabilities, patent portfolio sizes, and external relationships. We find that licensing firms with technological capabilities often pursue litigation until decision and engage in forum shopping. In contrast, litigation incidence, parties involved, and outcomes are primarily determined by patent characteristics, not entity types. Licensing business models drive the acquisition of certain types of patents that influence the outcomes of the patent system. We argue that patent policy should strengthen mechanisms to discover invention quality rather than focus on the amount of litigation or types of entities. 相似文献
