(International) R&D collaboration and SMEs: The effectiveness of targeted public R&D support schemes

This study analyses the impact and effectiveness of targeted public support for R&D investment at the firm level. We test whether the policy design aiming at incentivizing (international) collaboration and R&D in SMEs achieves input as well as output additionality. Our results show that the targeted public subsidies trigger R&D spending, especially so in internationally collaborating SMEs. We further evaluate the different impact of privately financed and publicly induced R&D investment on innovation performance. The results confirm that the publicly induced R&D is productive as it translates into marketable product innovations. While both types of R&D investments trigger significant output effects, the effect of policy-induced R&D investment on sales from market novelties is highest for international collaborators as well as for SMEs.

The accessibility of Chinese local government Web sites: An exploratory study

With the rapid development of Chinese e-government, Chinese citizens are encouraged to access e-government services as their convenience. However, the accessibility of Chinese e-government Web sites has been overlooked. This research study tries to provide an overview of the accessibility of Chinese local government Web sites. Three hundred twenty-four Chinese local government Web sites were examined to find out how accessible they are with reference to the Web Content Accessibility Guidelines 1.0 (WCAG) published by the World Wide Web Consortium (W3C). This research found that all the surveyed Chinese e-government Web sites failed one or more W3C's accessibility measures and thus many disabled Chinese people may have substantial problems to access them. Several valuable recommendations are made based on the research findings and the China's actual conditions.     

Understanding others Kellyian theory,methodology and applicationComprendre les autres la théorie de Kelly: methodologie et applicationEntendimiemto de los otros la teoría de Kelly: metodología y applicación

This article discusses Kelly's theory of personal constructs and its Repertory grid technique as means of revealing the nature of cultural differences and similarities. It shows how Kelly's theory relates to cognitive theory, implicit personality theory and subjective culture theory. According to Kelly, people and groups are best understood in terms of the ways they anticipate events. People are all psychologists since they employ constructs. These bases of discrimination are bipolar in nature and open to revision. A group's culture is summarized by its members' shared superordinate constructs. Kelly's Commonality Corollary explains that members of a group are similar because they use the same constructs to order events. Kelly's Sociality Corollary states that, in order to enter into a relationship with others, people need first to subsume the others' personal constructs. His custom-built Repertory grid elicits constructs by having a person decide how in a matrix other people, for example, are similar and different. In the rated grid form, each person or element is rated from most to least on the positive pole of each construct. Either principal components or cluster analysis or multidimensional scaling can reveal the interviewed person's superordinate dimensions of appraisal. As an emic technique, the grid is contrasted with the semantic differential and other fixed-format tests. A review of the personal construct literature shows that many individuals and cultural groups have been explained in their own terms. In this research, difference is construed as interesting and others are understood by construing their construction processes as a first step towards approval.
