How do foreign firms patent in emerging economies with weak appropriability regimes? Archetypes and motives     

Marcus Matthias Keupp  Sascha FriesikeMaximilian von Zedtwitz 《Research Policy》2012,41(8):1422-1439

Foreign firms patent in emerging economies with weak appropriability regimes at an increasing rate. This phenomenon constitutes a paradox since in such a setting foreign firms should have weak incentives to patent. In an attempt to resolve this paradox, we conducted an inductive analysis of 11 foreign firms that patent in such a setting, using the case of China as our empirical context. We identify four archetypes of foreign firms and three key antecedents the interaction of which determines which archetype a firm can be subsumed under.Our study complements the developed-economy focus of the extant appropriation literature by adding an international perspective. We extend previous econometric studies by identifying salient factors on the firm level that determine the extent to which a foreign firm patents in emerging economies with a weak appropriability regime, highlighting that the extent of a firm's motivation to maintain its freedom to operate can supersede imitability concerns. We also comment on the practical implications of these contributions for managers of foreign firms. Highlighting a structural conflict of interest between foreign firms from developed economies and the development goals of an emerging economy, we point to the generalizability of our results to a wide range of other emerging economies worldwide.  相似文献

A quality of interrelating: describing a form of meaningful experience on a wilderness river journey     

Marcus Morse 《Journal of Adventure Education & Outdoor Learning》2013,13(1):42-55

In this paper I identify the components of ‘meaningful experiences’ for participants on a wilderness river rafting journey. The research is phenomenologically informed, and includes interviews, journals, observations and follow-up emails from 32 participants on eight Franklin River (Tasmania) 10-day trips. It elicits individual perceptions of meaningful experiences and combines recollections to reveal the commonalities within those experiences. The research identifies two key recurrent ‘streams of experience’ that provide meaning. The two recurrent streams of experience involved, firstly, a feeling of humility and, secondly, being alive to the present. In this paper I focus on the stream of experience surrounding a feeling of humility, highlighting the qualities of the ways in which participants interrelated with their surrounding environments and the structure of such experiences. Additionally, I consider some unique elements of the wilderness river journey that contributed to the experiences that participants valued as meaningful.  相似文献

Historical perspective taking: A standardized measure for an aspect of students' historical thinking     

Ulrike Hartmann  Marcus Hasselhorn   《Learning and individual differences》2008,18(2):264-270

Researchers widely agree that learning history should involve more than learning historical facts and should include competencies of historical thinking. Various models of historical thinking view students' competency to take historical perspectives as a standard in history education. In this study we introduce a standardized measure for historical perspective taking (HPT) consisting of a short scenario set in the German Weimar Republic. We assessed students' HPT by using rating scales; our data were obtained in grammar schools from 170 German 10th graders. Latent class analyses identified three types of students with similar profiles of HPT. One was present-oriented and two showed more or less contextualized historical thinking. Students' history grades were connected to their HPT competency. We discuss limitations of the study and argue for further research on measures assessing students' historical thinking.  相似文献   

Performance strategies of US Olympians in practice and competition     

Marcus K. Taylor  Daniel Gould  Cristina Rolo 《High Ability Studies》2008,19(1):19-36

Until recently, no self‐report instruments have examined psychological skills use in both practice and competition. In light of the significant role of practice in sport performance outcomes, a need exists to measure these skills in both domains. This study was designed to investigate differences in performance strategies of US Olympians in both practice and competition. The Test of Performance Strategies was administered to 176 US participants in the 2000 Sydney Olympic Summer Games. Discriminant function analyses demonstrated significant differences between medalists and nonmedalists in both the competition and practice performance strategies. Furthermore, significant gender and age differences were identified for competition strategies only. The 16 subscales of the TOPS, with two exceptions, create an internally stable instrument with moderate predictive ability relative to quality of sport performance, gender, and age in this elite sample of athletes.  相似文献
