AbstractThis paper uses both univariate and multivariate Markov‐switching models to explore the characteristics of the regional business cycle phases in Taiwan. In particular, this paper provides novel evidence regarding the "turning‐point identification" puzzle in Taiwan that to date has not been fully resolved. We find that the regime‐switching behaviour of the common regional business cycle is consistent (or even precedes recession) with the business cycle expansion and contraction indicators used by the Council for Economic Planning and Development. This finding suggests that the common regional business cycle identifies the turning point after the 1990s. This finding also suggests that the employment growth index would be a great indicator for monitoring the business cycle in Taiwan.

ABSTRACTA key to the content diversity on user‐generated content platforms is what subject users choose to contribute on. This research investigates how two factors can shape contributors' subject choice decisions, namely, the amount of existing content and content contributed by online friends or "friend content." Our experimental findings show that both the amount of existing content and friend content can shape a contributor's subject choice decisions: ceteris paribus, contributors prefer subjects with less existing content and ones with friend content when the amount of existing content is the same. In addition, contributors' preference for subjects with friend content weakens as the amount of existing content on other subject's decreases. Our findings hold important implications for research and practice in user‐generated content platforms and beyond.

AbstractSpatial and temporal distribution characteristics of total nitrogen and ammonium nitrogen in the sediments, pore water and overlying water of Xiangxi Bay in China Three‐Gorge Reservoir were investigated. In surveys, the sampling was undertaken from six sites of Xiangxi Bay on three dates: 29 March 2009, 28 March 2010 and 17 August 2010. Mean values of total nitrogen and ammonium nitrogen contents in the sediments and pore water of Xiangxi Bay all increased with time, especially in summer. There were intimate relationships between internal nitrogen loading and water ecosystem. Correlation coefficients R were 0.7408 (between total nitrogen in pore water and total nitrogen in sediments) and 0.7483 (between total nitrogen in sediments and chlorophyll‐a in surface water), respectively. Total nitrogen concentration differences between pore water and overlying water were all positive and had good correlation with chlorophyll‐a concentration of Xiangxi Bay. The release of nitrogen in sediments had an important impact on phytoplankton growth in Xiangxi Bay.
