The intention to use mobile digital library technology: A focus group study in the United Arab Emirates

IGI Global (“IGI”) granted Brunel University London the permission to archive this article in BURA (http://bura.brunel.ac.uk).This paper presents a qualitative study on student adoption of mobile library technology in a developing world context. The findings support the applicability of a number of existing constructs from the technology acceptance literature, such as perceived ease of use, social influence and trust. However, they also suggest the need to modify some adoption factors previously found in the literature to fit the specific context of mobile library adoption. Perceived value was found to be a more relevant overarching adoption factor than perceived usefulness for this context. Facilitating conditions were identified as important but these differed somewhat from those covered in earlier literature. The research also uncovered the importance of trialability for this type of application. The findings provide a basis for improving theory in the area of mobile library adoption and suggest a number of practical design recommendations to help designers of mobile library technology to create applications that meet user needs

Does Market Sentiment Affect Order Submissions and Order Imbalances? Evidence from the Stock Index Futures Markets in Taiwan

[[abstract]]Using a database of Taiwan Stock Exchange Capitalization Weighted Index Futures (ticker symbol: TX) that allows us to identify the trader type for an order submission, we investigate the relationship between market sentiment and both order submissions and order imbalances, by trader type. We find more aggressive order submissions from individual traders during periods when market sentiment is highly fearful. For individual traders, the relationship between market sentiment and market order ratios is positive. Although the relationship between market sentiment and market order ratios is insignificant for institutional traders, the sample selection model (Heckman, 1979; Nawata, 1994; Guo and Fraser, 2010) demonstrates that institutional traders submit less market orders when market sentiment is fearful conditional on narrower spread. In addition, there is a negative relationship between positive market sentiment and market (limit) order imbalances. That is, when market sentiment is highly fearful, individual (institutional) traders submit more market (limit) sell orders. To the best of our knowledge, ours is the first study to empirically examine such a relationship although our findings are consistent with reports from practitioners and regulators that emphasize its importance (e.g. Report of the Staffs of the CFTC and SEC to the Joint Advisory Committee on Emerging Regulatory Issues, September 30, 2010). Our research indicates that regulators could better defuse periods of market turmoil by tying circuit breakers to an index of market sentiment, in addition to the range of a price decline
