This study aims to investigate whether epistemological assessment is a suitable approach to evaluate students’ learning of dietary knowledge via the use of an augmented reality (AR) information system. Students’ perceived dietary knowledge was compared before and after learning with the AR system. Two major questions were addressed: Did students improve their understanding of dietary knowledge after the use of AR information system? Did students gain more appropriate understanding of dietary knowledge after the use of AR information system?

A mixed-methods approach was used in the study. The mobile AR system was used among 65 volunteered non-nutrition-major college students recruited in campus. For promoting epistemological development of personal dietary knowledge, students practiced with life experiences to access daily dietary information. Pre- and post-tests of students’ understanding of dietary knowledge were compared. Interviews with 20 students were used for gathering in-depth research data to analyse students’ epistemological understanding of dietary knowledge.

The epistemological assessment indicated an improvement in learning after the use of the AR system. Students gradually gained awareness of dietary knowledge and changed their perceptions of their dietary behaviours. Epistemological approaches to the analysis of students’ conceptual change in dietary knowledge revealed a significant increase in the mean nutritional concepts (p < 0.01) and a decrease in their mean misconceptions (p < 0.001) after learning via the mobile nutrition monitoring system. Learning assessment of 65 students also indicated a significant increase from the post-test after learning with the system (p < 0.0001).

This study might have its limitations, as it only assessed learning using a pretest-posttest design for a specific learning context over a short period of learning time. The use of interviews based on the epistemological approach might have its limitations in the interpretations of the phenomenon. Future implementations can also be extended to different populations to promote self-monitoring dietary behaviours.

The findings of this study will contribute to the application of AR in learning about dietary knowledge. The research involving in-depth observation of students’ learning relevant to personal nutritional information needs via mobile AR might provide potential contributions to dietitian professionals and health education.

Collaborative arts incorporate theatrical elements including sound, movement, text, design, technology and visual elements into a synthetic original form of art. This paper examines a sub-category of collaborative arts, New Music Theater, in the contemporary context from the 1980s onwards in Hong Kong.

Interviews with artists Kung Chi Shing, Steve Hui and Amy Chan exhibit their personal creative and collaborative experiences.

These interviews provide a view of the current practice of New Music Theater in Hong Kong.

This paper highlights the emergence of a new art form in Hong Kong and fills a gap in the relevant literature.

The purpose of this paper is to examine market reactions to private equity placements and intra-industry information spillover effects in the Taiwan Stock Exchange.

The authors first use the market model to compute the abnormal announcement returns. To examine the joint impact of the private investment in public equity (PIPE) purposes and the lead investor industry, the authors regress the issuers’ cumulative abnormal returns (CARs) on the dummy variables of PIPE purposes and the lead investor industry. To study the spillover effects, the authors regress the rivals’ CARs on the issuers’ CARs, PIPE purposes, and the lead investor industry. Finally, the industry Herfindahl index is used as a proxy for the market power of issuers and rivals to examine its impact on the spillover effects.

The authors find that issuing firms experience positive abnormal returns during the announcement period. Issuers enjoy more positive market reactions when the proceeds of offerings are primarily used to establish a long-term strategic alliance or to integrate business and when the lead investor is in the same industry. Furthermore, the authors show that the contagion effect dominates the competitive effect in private equity placements at the aggregate level. At the subsample level, the authors find competitive effect overpowers contagion effect when the purpose of offerings is primarily used to establish a long-term strategic alliance or to integrate business and when the lead investor is in the different industry. Finally, the authors show that rivals with relative lower market power enjoy more positive contagion effects.

First, the analysis documents the simultaneous importance of both the purposes of private offerings and the lead investor’s industry on announcement reactions, which shed new light on the positive abnormal returns during the announcement period. Second, the study adds to the literature on the information spillover effects by analyzing the role played by purposes of offerings and rivals’ market power. This paper provides a more complete picture of the offsetting competitive and contagion effects.
