Getting the word out on Twitter: the role of influentials,information brokers and strong ties in building word-of-mouth for brands

Using a sample of over 5300 tweets from top global brands, this study investigated how different types of users can influence brand content diffusion via retweets. Twitter users who influenced followers to retweet brand content were categorized as (1) influentials, because of their above average ability to influence others to retweet their tweets (in general), (2) information brokers, because of their position connecting groups of users or (3) having strong ties, because of their high percentage of friends in common and a mutual friend–follower relationship with the influenced follower. The results indicate that influentials and information brokers are associated with larger number of retweets for brand content. In addition, although information brokers have a larger overall influence on retweeting, they are more prone to do so when influentials are mentioned in the brand tweet, providing support for the strategy that aims to associate the brand with influential users.     

The link between supply chain fit and financial performance of the firm

The bottom-line financial impact of supply chain management has been of continuing interest. Building on the operations strategy literature, Fisher's (1997) conceptual framework, a survey of 259 U.S. and European manufacturing firms, and secondary financial data, we investigate the relationship between supply chain fit (i.e., strategic consistencies between the products’ supply and demand uncertainty and the underlying supply chain design) and the financial performance of the firm. The findings indicate that the higher the supply chain fit, the higher the Return on Assets (ROA) of the firm, and that firms with a negative misfit show a lower performance than firms with a positive misfit.

The development of the Yangtze River container port system

This paper sheds an empirical light on port development patterns by discussing the structure and the development of the Yangtze River ports system. We argue that the Yangtze River system is going through a regionalization phase, mainly in relation to the port of Shanghai. This process started on the lower Yangtze but is now also moving upstream. The transition towards the port regionalization phase is typically a gradual and market-driven process that mirrors the increased focus of market players on logistics integration. This paper builds on the existing literature on port systems and adapts port development models to river ports. Furthermore, we employ some statistical techniques that are common to the analysis of port systems, and introduce some techniques that have not been used much by transport geographers in ports. This paper will address the dynamics in the Yangtze River ports system by analyzing the level of cargo concentration and the degree of inequality in operations of the container ports. The paper also assesses observed differences in development of ports in different areas along the river (upstream/downstream) and reflects on the role of ownership structures in shaping regional load centre networks.     

Intellectual property rights as development determinants

Abstract While intellectual property rights (IPRs) are the key drivers of economic performance in R&D based growth models, they have not been fully explored in empirical development studies. We introduce IPRs to this literature, using Two‐Stage Least Squares Bayesian Model Averaging to address endogeneity and model uncertainty at the instrument and income stages. We show that IPRs exert effects similar to ‘Rule of Law’ and therefore provide robust evidence that both physical and intellectual property rights are crucial development determinants. We document that unenforced IPRs exert no effect on development. Instead, it is the level of enforced IPRs that causes development.     

Time-varying Integration and International diversification strategies

This paper investigates the impact of globalization and integration on the relative benefits of country and industry diversification. Unlike previous models, our factor model allows asset exposures and volatilities to vary with both structural changes and temporary fluctuations in the economic and financial environment. First, we find that globalization and integration have lead to a gradual convergence of country to industry betas, especially in Europe. Second, the structurally-driven increase in market betas is accompanied by a gradual decrease in country-specific risk. Third, even though the edge has structurally decreased, geographical diversification continues being superior to industry diversification.     

Concentration and the formation of multi-port gateway regions in the European container port system: an update

The European container port system features a unique blend of different port types and sizes combined with a vast economic hinterland. This paper provides an update of the detailed container traffic analysis developed by Notteboom (1997) by extending it to the period 1985–2008 and to 78 container ports. The paper also aims at identifying key trends and issues underlying recent developments in the European container port system. These trends include the formation of multi-port gateway regions, changes in the hinterland orientation of ports and port regionalization processes. While the local hinterland remains the backbone of ports’ traffic positions, a growing demand for routing flexibility fuels competition for distant hinterlands between multi-port gateway regions. The prevailing assumption that containerisation would lead to further port concentration is not a confirmed fact in Europe: the European port system and most of its multi-port gateway regions witness a gradual cargo deconcentration process. Still, the container handling market remains far more concentrated than other cargo handling segments in the European port system, as there are strong market-related factors supporting a relatively high cargo concentration level in the container sector.     

Governance factors enabling knowledge transfer in interorganisational development projects

In this study we examine governance factors affecting knowledge transfer in interorganisational development projects. There is a gap in the literature indicating a need for more insights into processes of knowledge sharing and governance of interorganisational development projects. By using cases from the Dutch construction industry, we discus how interorganisational development projects are governed and what impact this has on knowledge transfer between the firms involved. We find that knowledge transfer towards participating firms cooperating in an interorganisational development project is positively influenced when partners govern their cooperation by using mutual trust and contract complementary.
