Motives to patent: Empirical evidence from Germany 总被引:4,自引:0,他引:4
Against the background of the patent upsurge, we first analyse the role of patenting and alternative instruments to protect intellectual property, based on a sample of German companies active in patenting. In a second step, we investigate the motives to patent, considering sector and company size effects. We find that company size matters, both for the importance of instruments and the motives to patent. Especially important are the new strategic motives to patent, like using patents to improve a company's own position in negotiations with partners, licensees and the financial sector, or to use patents as incentives for R&D personnel or performance indicators—these correlate positively with company size. We derive some possible challenges for future patent policies from these insights. 相似文献

Summary Adults have tried to identify and to seek complex explanations for Potter's success. She explained it simply: “It is much
more satisfactory to address a real live child. I often think that was the secret of the success of Peter Rabbit; it was written
to a child—not made to order” (Lane, 1976, p. 183). She felt the more spontaneous the pleasure, the better the result.
You are encouraged to heed Potter's advice. Address the real live child as you enjoy the pleasure of this adventure into the
life and times of Beatrix Potter and all her animal friends. 相似文献

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country. 相似文献

There is a vast terrain of emerging research that explores recent innovations in digital games, particularly as they relate to questions of teaching and learning science. One such game, Citizen Science, was developed to teach players about the practice of citizen science as well as lake ecology. Citizen science is a pedagogy that has a long history within the scientific community, engaging the public in ongoing community and environmental surveys to collect data for existing small-scale studies. More recently, citizen science has gained traction as an educational context for teaching and learning science in ways that connect to students?? lives and interests. By placing citizen science within the realm of digital worlds, Matthew Gaydos and Kurt Squire invite new possibilities for knowledge to become more kinetic, moving in multiple directions. In this article we discuss some of the tensions we experienced as we explored the digital game, Citizen Science. We highlight questions about narrative and complexity, emergent game play and transfer to encourage thinking about the development and implementation of games such as Citizen Science. 相似文献

We investigated the use of self-regulated study strategies among undergraduates with dyslexia by means of extensive web-based diary data, comparing their strategy use to that of matched students without dyslexia who completed the diary in the same period. Additionally, we examined the perceived benefits of using the recorded strategies in both groups, as well as relationships between the recorded strategies and perceived self-efficacy and academic performance. Results indicated that across lecture, individual study, and social study contexts, students with and without dyslexia recorded a comparable, broad range of strategies, yet students with dyslexia seemed to use particular visual and social strategies more consistently than did students without dyslexia. Across the three study contexts, both students with and without dyslexia also perceived the strategies they recorded in the diaries to be quite beneficial, but with particular visual and social strategies seemingly perceived as more helpful by students with dyslexia. Finally, self-regulated study strategies were positively related to perceived self-efficacy and academic performance among the students with dyslexia but not among the students without dyslexia. We discuss the possibility that the diary method used to assess strategy use among students with dyslexia in different study contexts over time was more appropriate for revealing the breadth and value of their strategy repertoire than the decontextualized, one-time questionnaire and interview approaches used in prior work. 相似文献

This essay critiques the main responses to 9/11 by US intellectuals and analyzes how these reactions reinforced a determined ignorance of the consequences of US economic, foreign, and military policy and a further depoliticization of the culture in general. As a class, faculty have the resources—material and intellectual—to make a serious contribution to progressive political and social change in the world. They need to start putting those resources to work. 相似文献

Determining what factors predict media learning is an important avenue of research for the field of mass communication. The present study provides a comparative investigation of two models of media learning: the cognitive mediation model and the information utility model. Participants (N = 1,076) read a news article related to scientific discoveries relevant to cancer prevention and responded to all constructs of the two models. Recognition and comprehension were used to measure knowledge acquisition. Results generally support previous predictions of each model, though predicted variance remains small. In addition to testing the existing models, a modified cognitive mediation model using a key construct related to information utility—perceived relevance—was tested. The refined cognitive mediation model offered a more nuanced understanding of certain causal mechanisms but did not result in a meaningful change in predictive power of the model. Implications of the theoretical comparison and integration are discussed. 相似文献
