Design rationale is design information that explains why an entity is designed as it is. This paper investigates how the documentation process and the use of documents in service design projects influence the reuse of design information across projects.

This study analyzes two sets of data collected through interviews and field observation. It first applied Lund's (2004) four elements of documentation process to categorize the collected data. Then it used bottom-up data analysis approach to identify patterns of the documentation process.

The author speculates designers' focus on certain documents' social aspect instead of material aspect influences how they reuse design information across projects. Some documents are important because they represent a consensus, and some are important because of the document producers rather than its content. The author also found a similarity between economists and service designers by comparing the study results with Harper and Sellen's (1995) findings. Based on the comparison, the author concludes that detailed research reports are easily reusable across design projects. Finally, although the author observed that designers are using templates to explicate design rationale, the created content is not used across projects.

This study identifies six types of documents that are commonly created in service design projects, three types of producer involvement and three types of provisional design outcomes. It also provides two suggestions for designers to reuse design information across service design projects better and two implications for future study.

The purpose of this paper is to propose an indexing and teaching focus mining system for lecture videos recorded in an unconstrained environment.

By applying the proposed algorithms in this paper, the slide structure can be reconstructed by extracting slide images from the video. Instead of applying traditional shot‐change detection methods for general videos, a new edge‐based shot‐change detection algorithm is designed specifically for lecture videos. Besides, light influence and occlusions in the lecture video can be removed to obtain more accurate results. Moreover, the teaching focus can be extracted according to instructors' behavior based on the analyses of visual and audio information extracted from the lecture video.

Experiment results show the feasibility of the proposed method, that is, the slide shots can be correctly detected even if the illumination conditions are variant or the slides are obstructed by the instructor or students, and the teaching focus can be extracted to provide learners with an efficient way to study.

This paper provides only technical experiments, but lacks complete educational study. In the future, more subjective tests will be designed to examine the educational effects on students.

This paper proposes a practical indexing and teaching focus mining system for lecture videos which can help students learn.

The proposed algorithms for indexing and teaching focus mining are derived and applied in lecture videos in this paper.

As the application of gamification is gaining great attention and has grown increasingly, thousands of these applications can be easily obtained from mobile phone stores, thus causing intensified competition and discontinuance of use accordingly. Besides, though understanding what factors influence the discontinuance of use of information systems (ISs) is critical for theoretical as well as practical reasons, studies pertaining to the saliency of the final phase, termination of an IS, are still limited. As such, the purpose of this paper is to propose a holistic view to fulfill the above-mentioned research gaps based on the expectation-confirmation model with other salient factors such regret, habit and gamification app values.

The context of a fitness gamification app is investigated. A total of 210 valid responses were received, and structural equation modeling was applied for data analysis.

The findings of this paper are as follows: among all factors influencing discontinuance intention, regret is the strongest, habit is second and gamification is third; among all factors affecting user satisfaction, gamification app value is the strongest, confirmation is second, perceived usefulness (PU) and perceived ease of use are third and regret is the last one; for factors influencing users’ habits, satisfaction is the strongest, following by PU and frequency of prior use; confirmation negatively influences the degree of regret; and confirmation positively influences PU.

This study highlights the important determinants influencing users’ discontinuance intentions in the context of gamification apps by incorporating two overlooked factors, regret and habit. Besides, this study suggests that app designers can not only increase user’s perceived value through external cooperation with other alternatives, but can be through internal enhancement with diverse services development as well.

Social media is still influencing consumers and is extending social commerce (S-Commerce) use. Different social media activities can influence the users' trust and e-satisfaction at different levels, which in turn influence the purchase intentions. This is evident for the food and beverage industry as S-Commerce mediated by social media can help realise a shorter time to market and meet buyer demands. In addition, credibility factors may influence trust and purchase intentions. Understanding the various factors of influence such as social constructs, namely ratings, reviews and referrals; design constructs such as credibility and features and behavioural constructs such as trust, satisfaction and motivation; and analysing the relationship between these factors and how they influence purchase intentions can provide deeper insights into S-Commerce research, decision-making process and purchase intentions particularly from a food and beverage context.

Drawing on trust through social media activities and surface credibility as well as e-commerce satisfaction, the authors have proposed a research model to investigate the purchase intention of consumers in S-Commerce platforms. Survey data were collected from six countries in Asia and analysed using SEM-PLS.

Results indicated that both trust and surface credibility significantly influence e-commerce satisfaction leading to purchase intention. Furthermore, surface credibility, which is a novel predictor for purchase intention in S-Commerce context, is highly significant on e-commerce satisfaction. Besides, encouraged by surface credibility, it was identified that trust significantly affects e-commerce satisfaction and results in purchase intention. This research adds contribution to theory and practice in S-Commerce stream as discussed at the end of the paper.

The results of this research contribute to the S-Commerce literature and have practical implications for practitioners in the food and beverage industry. As such, focussing on these constructs, this paper analyses the relationship between the social media activities, trust, e-commerce satisfaction, surface credibility and intention to buy.

Integrated reporting (IR) aims to improve the quality of information available to capital providers. While IR is associated with decreases in investor uncertainty and increases in firm value, it is unclear how IR information directly influences investment decisions. This paper aims to investigate the investment considerations of Taiwanese investors and their initial impressions of the International Integrated Reporting Framework (IIRC Framework). In doing so, this study examines the relationships between investment considerations and the IIRC Framework’s concepts.

Semi-structured interviews were undertaken with 16 investors in Taiwan. Thematic analysis was used to analyse the data collected.

In addition to economic and financial outlook, competitive advantages and ownership structure, Taiwanese investors emphasise management credibility as an important factor that influences investment decisions. Investors are reliant on private information sources and quantitative data. Sustainability disclosures and sustainability performance beyond legal requirements are often not considered. Taiwanese investors lack awareness of the IIRC Framework and are sceptical about the premise that integrated reports can provide information material to investment appraisal. The assertion that integrated reports reduce information asymmetry and influence investment decisions has to be treated with caution.

Self-selection bias and a potential lack of transferability in the findings are issues inherent in the research method and sample used.

IR information needs to be frequently updated rather than disclosed in a periodic report. Furthermore, integrated reports need to demonstrate a direct link between non-financial performance and financial value creation.

Mandating the supply of integrated reports is unlikely to influence investors’ capital allocation decisions unless investor demand is a driver of the regulation.

This study is one of the few to investigate IR from the investor’s perspective. Observations from this preliminary study warrant further investigations into the relevance of IR to investment communities globally.
