服务业创新的新熊彼特定义：基于新分类法的概念探讨

创新是一项复杂的过程并具有多面性。在众多以创新与生产率之间联系为主题的研究中，由于数据限制，往往只采用单一指标来测度创新。本文对这种方式提出了质疑，认为这种研究方法可能会系统地偏向于某类经常通过参与创新活动以达到各种商业目的的公司或产业。为了更好地测度创新，本文介绍了一种创新索引，即以潜变量模型为基础的含有多项创新指标的线性指标组合。这一尝试得到加拿大制造业公司的大量微观数据组合的支持。     

Partnership Programs in U.S. Schools: Their Development and Relationship to Family Involvement Outcomes

This study examined data from over 300 U.S. schools on their efforts to develop high quality programs of school, family, and community partnerships. Analyses show that elementary schools, schools with greater support from parents, teachers, and the community; and schools that evaluated progress reported higher quality partnership programs over time. Higher quality programs were associated with wider implementation of parent-child interactive homework, higher levels of parent volunteering, and more parents on school decision-making committees. Results identify factors that could help schools develop quality partnership programs and suggest that these programs translate into higher levels of family involvement in students’ learning.     

Cultural differences in the perception of critical interaction behaviors in global virtual teams

We investigated whether members of virtual teams from the U.S., India, and Belgium perceived the same interaction behaviors to be critical for team functioning as Dutch members from an earlier study. Thirteen virtual team workers from the U.S., 11 from India, and 11 from Belgium were interviewed by means of the Critical Incident Technique Flanagan [Flanagan, J. C. (1954). The critical incident technique. Psychological Bulletin, 51, 327–358]. The total number of critical incidents from all countries was 493 and most incidents could be grouped into the same 13 categories as those found in the original Dutch study. However, the results showed that the distributions of the critical incidents from the American, Indian, and Belgian respondents differed from those of the Dutch. Indian and Belgian respondents also mentioned a new category of critical incidents: Respectfulness. The cultural differences were interpreted by means of Hofstede's [Hofstede, G. (2001). Cultures consequences: comparing values, behaviors, institutions, and organizations across nations (2nd ed.). Thousand Oaks, California, U.S.: SAGE Publications] dimensions.     

The effect of video-feedback on the learning of the tennis service by intermediate players

Effects of video-feedback on improvement of the tennis service were investigated in subjects having at least 2 years of playing experience in tennis. The experiment was carried out in an indoor tennis hall under normal training conditions. Subjects were randomly divided into three groups: a video-feedback training (VFT) group, a traditional training (TT) group and a control group, each consisting of 22 subjects. While the subjects of the control group received no training at all, subjects in both the VFT and TT groups were trained twice weekly during 5 consecutive weeks. Each training session lasted 40 min, of which 30 min was spent on actual practice in training of the service. The remaining 10 min was spent on watching, analysing and discussing video recordings of either their own service performed during the training session (VFT group), or ground strokes and volleys of top level players (TT group). Both the VFT and TT group showed significantly greater improvements in both achievement scores and form (technique) scores than did the control group. No differences, however, could be demonstrated between the VFT and TT group, indicating that the subjects of the former group did not benefit from the video-feedback they received. While form scores correlated significantly (P less than 0.001) with the velocity of the served ball, no such relation between form scores and spatial accuracy was apparent.     

Building Your Licensing and Negotiation Skills Toolkit

Licensing and the negotiating of electronic resources can be a daunting task for librarians who lack the proper skill sets and are unfamiliar with the intricacies of publisher agreements. Claire Dygert broke down the individual elements of a standard licensing agreement and explained the importance of protecting the rights of libraries. By providing insight from her years of experience, librarians learned how to develop a support network, build confidence, and be more effective negotiators.     

Priming and Fake News: The Effects of Elite Discourse on Evaluations of News Media

Fake news has become a prominent topic of public discussion, particularly among elites. Recent research has explored the prevalence of fake news during the 2016 election cycle and possible effects on electoral outcomes. This scholarship has not yet considered how elite discourse surrounding fake news may influence individual perceptions of real news. Through an experiment, this study explores the effects of elite discourse about fake news on the public’s evaluation of news media. Results show that exposure to elite discourse about fake news leads to lower levels of trust in media and less accurate identification of real news. Therefore, frequent discussion of fake news may affect whether individuals trust news media and the standards with which they evaluate it. This discourse may also prompt the dissemination of false information, particularly when fake news is discussed by elites without context and caution.
