The dynamic relationship between stock returns and trading volume: Domestic and cross-country evidence

Abstract: This paper examines the dynamic relations – causal relations and the sign and magnitude of dynamic effects – between stock market trading volume and returns (and volatility) for both domestic and cross-country markets by using the daily data of the three largest stock markets: New York, Tokyo, and London. Major findings are as follows: First, trading volume does not Granger-cause stock market returns on each of three stock markets. Second, there exists a positive feedback relationship between trading volume and return volatility in all three markets. Third, regarding the cross-country relationships, US financial market variables, in particular US trading volume, contains an extensive predictive power for UK and Japanese financial market variables. Fourth, sub-sample analyses show evidence of stronger spillover effects after the 1987 market crash and an increased importance of trading volume as an information variable after the introduction of options in the US and Japan.

A critical review of the use of virtual reality in construction engineering education and training

Abstract: Virtual Reality (VR) has been rapidly recognized and implemented in construction engineering education and training (CEET) in recent years due to its benefits of providing an engaging and immersive environment. The objective of this review is to critically collect and analyze the VR applications in CEET, aiming at all VR-related journal papers published from 1997 to 2017. The review follows a three-stage analysis on VR technologies, applications and future directions through a systematic analysis. It is found that the VR technologies adopted for CEET evolve over time, from desktop-based VR, immersive VR, 3D game-based VR, to Building Information Modelling (BIM)-enabled VR. A sibling technology, Augmented Reality (AR), for CEET adoptions has also emerged in recent years. These technologies have been applied in architecture and design visualization, construction health and safety training, equipment and operational task training, as well as structural analysis. Future research directions, including the integration of VR with emerging education paradigms and visualization technologies, have also been provided. The findings are useful for both researchers and educators to usefully integrate VR in their education and training programs to improve the training performance.

The conceptual change approach to improving teaching and learning: An evaluation of a Hong Kong staff development programme

Abstract: This paper reports a study ofthe effectiveness of an innovative approach tostaff development, the conceptual changeapproach, which attempts to change teachers'frameworks for conceptualising teaching andlearning. The evaluation investigated theprogramme at three levels: the impact on theconceptions of teaching of the participants,the resultant impact on teaching practices, andthe consequential effect on student learning.Encouraging results were obtained. Theprogramme brought about detectable conceptualchange or conceptual development in two-thirdsof the sample group. Subsequently, all the`changed' teachers received better ratings ontheir teaching practices from their students inthe following academic year while none of thosewho did not change their conceptions showedsimilar gains in student rating scores. Aresultant positive impact on their students'studying approaches was observed for half ofthe teachers who changed their conceptions.
