国际技术溢出:基于进口传导机制的实证研究

本文研究以进口贸易为传导机制的国际技术溢出对我国技术进步(全要素生产率)的促进作用。协整检验结果表明通过进口贸易传导机制,贸易伙伴国R＆D投入、国内科技投入对我国全要素生产率的提高具有显著的促进效应。进一步的误差修正模型分析结果表明贸易伙伴国研发投入、财政科技投入对我国全要素生产率的促进作用具有一定的滞后效应。

Online social viewing: Cross-cultural adoption and uses of bullet-screen videos

ABSTRACT

Bullet-screen technology, an innovative way of interacting with online videos, allows viewers to contribute comments that simultaneously appear over videos. Popular in East Asia, the technology is making its way to American audiences. This study employed a comparative qualitative focus group approach to explore how American and Chinese viewers responded to and interacted with this new format of online videos. Three themes emerge from this investigation: (1) the unique affordances of this technology; (2) barriers to adoption and usage; and (3) cultural differences that impact the user experience. The theoretical and practical implications for bullet-screen technologies are discussed.

Use and evaluation of a technology-rich experimental collaborative classroom

In order to pilot a shift towards greater use of collaborative learning in our higher education programs, the University of Hong Kong has invested in the development of a prototype technology-enhanced collaborative learning space. The space was created by retrofitting a vacant studio, turning it into an innovative classroom space in which collaborative learning is promoted and facilitated both through the provision of technology and by the physical layout of the room. We have used the space to pioneer collaborative learning both by holding professional development workshops for faculty in the room and also by helping academic staff to run experimental courses in the learning space. The opportunity to offer professional development and support for academic staff in this environment is particularly valuable as it ensures they do not simply deliver traditional didactic lectures in a space designed to promote interactive student learning and engagement. By using the space as a ‘student’ they are able to consider how they may use collaborative learning environments with their students. This paper describes use of the room for professional development of academic staff and also provides two examples of the use and evaluation of the room by faculty who used the room to teach experimental classes.
