PolyU Tops the List of Maritime Research Article Producers in Chinese Economies
PolyU published the highest number of maritime research papers among institutions in Chinese economies, achieving the highest weighted score and the second highest impact score during the years 2000 to 2015.
"Dynamic Changes in Maritime Research Capability in Chinese Universities" has been published by Hindawi, an open access publisher. This study refers to China in the broad sense of Chinese economies, including mainland China, Hong Kong, Taiwan and Singapore. It analyses 65 maritime and transportation journals indexed in the Social Sciences Citation Index (SSCI) and Science Citation Index (SCI) between 2000 and 2015. The rankings are based on three indicators: total number of articles, weighted score (an indication of author contribution), and impact score.
The study examines the top 50 authors and affiliations in China in the field of maritime transportation in comparison with their world ranking. Ranking by affiliation shows that PolyU has the highest number of papers (176) and the highest weighted score (99.9). Ranking by author shows that Ir Professor T.C. Edwin Cheng, the Faculty Dean, is second in terms of the number of papers published.

The authors study whether social media can play a negative information role by impeding price discovery in the presence of highly speculative rumors. They focus on merger rumors, where most do not materialize. They find that merger rumors accompanied by greater Twitter activity elicit greater immediate market reaction even though rumor-related Twitter activity is unrelated to the probability of merger realization. The price distortion associated with tweet volume persists weeks after a rumor and reverses only after eight weeks. The price distortion is more pronounced for rumors tweeted by Twitter users with greater social influence, for target firms with low institutional ownership, and for rumors that supply more details. Their evidence suggests that social media can be a rumor mill that hinders the market's price discovery of potentially false information.
