Factors predictive of black students' communication with the administration and students at a predominantly white university     

Warren Watson  Ina Siler 《Int J Intercult Relat》1984,8(3):255-267

Black students' interaction with a predominantly white university's administration, faculty, and students appears to be a central issue in current study of black student success in college. This study examined personality and situational factors predictive of black students' communication with such a university's administration, faculty, and students. The development of an instrument describing environmental and social concerns of black students demonstrated reasonable predictive validity of communication with the administration and white students. Feelings about the social environment and tendencies of communication anxiety were among the strongest predictors of black students' communication.  相似文献   

From knowledge to added value: A comparative, panel-data analysis of the innovation value chain in Irish and Swiss manufacturing firms     

Stephen Roper  Spyros Arvanitis 《Research Policy》2012,41(6):1093-1106

The innovation value chain (IVC) divides the innovation process into three separate links or activities: knowledge gathering, knowledge transformation and knowledge exploitation. Here, we report a comparative panel data analysis of the IVC in Ireland and Switzerland. Both economies are small, very open and depend significantly on innovation to maintain competitive advantage. In recent years, however, R&D and innovation growth in Ireland has been markedly stronger than that in Switzerland. We investigate these differences through the ‘lens’ of the IVC. Significant similarities exist between some aspects of firms’ innovation behaviour in each country: strong complementarities emerge between external knowledge sources and between firms’ internal and external knowledge. And, in both countries, in-house R&D and links to customers prove important drivers of innovation. Innovation drives productivity growth in different ways in the two countries, however, through product change in Switzerland and through process change in Ireland. Other differences in the determinants of innovation performance linked to ownership and firms’ institutional context emphasise the systemic nature of innovation and the legacy of past patterns of industrial development.  相似文献   

Selective search, sectoral patterns, and the impact on product innovation performance     

Christian Köhler 《Research Policy》2012,41(8):1344-1356

The shift toward more open and interconnected innovation activities has been a major topic in recent academic and practitioner discussions. Firms must connect their in-house R&D activities with external partners, such as leading customers or universities, to increase the effectiveness of their innovation activities. Hence, management needs to define where to search for valuable knowledge in its environment. In this paper we argue that knowledge search has to reflect the heterogeneity of various knowledge sources with regard to the knowledge they can provide and how these sources can be activated. We hypothesize that search strategies driven by science, suppliers and the product market will contribute differently to innovation success with new-to-market versus imitated products. Moreover, we explore the effect of these types of knowledge search within different sectoral patterns of innovation. Our empirical analysis rests on a sample of almost 5000 firms from five Western European countries. The results support our hypotheses and highlight the potentials and shortcomings of different types of knowledge search.  相似文献   

The impact of national research funds: A regression discontinuity approach to the Chilean FONDECYT     

José Miguel Benavente  Alessandro Maffioli 《Research Policy》2012,41(8):1461-1475

This paper analyses the role of national research funds in promoting scientific production in emerging economies. The study focuses on the impact of the Chilean National Science and Technology Research Fund (FONDECYT). The analysis uses data drawn from international sources of bibliometric information combined with the administrative records of the program's executing unit. To measure the program's impact, we implement a regression discontinuity (RD) design on principal researchers who applied for funding between 1988 and 1997 considering as outcomes both quantity (publications up to 2002) and quality (citations up to 2005) of their scientific production. Our results show significant and positive impact in terms of publications, but no impact in terms of quality of scientific production in the proximity of the program's threshold ranking.  相似文献   

心理语言学在外语教学中的运用     

张冬楠  王朝培 《科教文汇》2012,(17):122-123

心理语言学兴起于20世纪50年代,是语言学的一个重要分支,是一门研究语言活动中的心理过程的学科,是对语言的生成、结构、语用、语言习惯等的研究。外语教师应该认真学习研究心理语言学,并运用心理语言学的理论,去指导我们的外语教学。  相似文献
