Structural change in search engine news service: a social network perspective

This research investigates structural change made by Naver's online news section and how it has impacted the overall traffic flow of Korea's online news. This paper examined 45 websites in 2008 and 2010, and the total number of pages viewed within these sites was considered in the analysis. Social network analysis was applied to study the relationships between the news sites. The analysis through degree centrality and Bonacich powers shows that there has been a shift in market leadership. In 2007, Naver, the top search engine in Korea, stepped down from its leading position after they started to provide news services. Daum, the second largest search engine, has taken over the central position as the most influential news site. Based on the results of this study, practical implications for online service markets and theoretical implications for online services are recommended accordingly.clos

What sparks quality-driven change programmes in not-for-profit service sector? Some evidence from the voluntary sector

Despite the massive amount of attention paid to quality management in privately owned manufacturing and services firms and publicly owned organisations, few scholars have attempted to examine the application and outcomes of various quality-driven change initiatives in the context of voluntary sector organisations. This paper reports on the application of quality management programmes in terms of logic of adoption, implementation decisions and the resultant performance outcomes in a sample of voluntary sector organisations. Using a multiple case study design of three firms, the findings largely support the view that initiating quality-oriented change programmes poses a unique challenge to the management on two fronts: first, management logic and understanding for adopting quality initiatives, and the ability of the management to appreciate the synergetic relationship between efficiency gains and legitimacy concerns so that a continuous learning environment will follow. Drawing on insights from institutional theory literature, we shed light on the complexities inherent in the sector that necessitate a reappraisal of the logic of quality initiatives adoption, which in turn create a dilemma and indeed build resistance for the management to embody an unconditional commitment to the strategic importance of quality. The paper concludes with several working propositions and discusses the practical implications of the findings

Interorganizational collaboration and innovation: towards a portfolio approach.

In the literature on innovation, interorganizational collaboration has been advanced as beneficial for the innovative performance of firms. At the same time, large-scale empirical evidence for such a relationship is scarce. This article examines whether evidence can be found for the idea that interorganizational collaboration supports the effectiveness of innovation strategies. This article empirically addresses this research question by analyzing data on Belgian manufacturing firms (n 5221) collected in the Community Innovation Survey, a biannual survey organized by Eurostat and the European Commission aimed at obtaining insights into the innovation practices and performance of companies within the various European Union (EU) member states. Tobit analyses reveal a positive relationship between interorganizational collaboration and innovative performance. At the same time, the impact on innovative performance differs depending on the nature of the partner(s) involved. These findings strongly suggest the relevance of adopting a portfolio approach to interorganizational collaboration within the context of innovation strategies
