The aim of this paper is to investigate the major differences between the government's role in building energy efficiency (BEE) in China and three developed countries, and to further the understanding of market expectations of the most effective government measures to encourage BEE development in China.

The approach taken was: establish a framework for a critical comparative study; compare and assess the BEE promotion measures available to governments in the USA, Canada, the UK and China; survey the BEE market expectations of building design professionals to better understand the favourable measures the Chinese Government could take to further promote BEE; and triangulate the findings of the comparative study and questionnaire survey to develop recommendations for BEE promotion in mainland China.

Economic incentives are important for BEE promotion at the current stage, but they are lacking in China. Active government interventions, such as adjusting energy pricing and implementing BEE legislation, are needed in China if BEE is to become economically viable and efficient.

Owing to limited resources, the questionnaire survey did not reach every part of China. A further study should be carried out to extend the investigation to more areas of China and to obtain wider stakeholder coverage.

The originality of this paper lies in its development of a theoretical framework to further understanding of the government's role in BEE promotion and its use of first‐hand data collected from industry to verify market expectations of that role in China.

Nonprofit Organisations (NPOs) receive their funding in three major types: government subvention, donations and fees collected for services provided. While the contributors do not normally act as the decision agents, the potential existence of agency problem has to be dealt with. This paper investigates whether effective monitoring of principal‐agent relationship exists in NPOs in Hong Kong, which may be perceived to be attached to different types of funding provided to NPOs. While findings from previous studies suggest that NPOs' expense level will be low when they are subject to external monitoring, our results reveal that the expense level of NPOs is similarly associated with the type of funding. More specifically, sizeable donations induce a perception of effective external monitoring on the decision agents, which leads to the adoption of a lower expense level. On the other hand, due to the weak control that can be imposed by existing regulatory framework and disclosure requirements, government subvention and fees collected do not seem to impose any effective monitoring effects on NPOs.

Investors in Hong Kong tend to overreact to good news but not to bad news in the short run. ‘Winner’ stock portfolios making abnormal gains on the event day tend to make abnormal losses in the subsequent test period. On the contrary, abnormal losses persist in the test period for the loser stock portfolios. This may be attributable to the speculative nature of the Hong Kong market and thin trading of small‐sized stocks. Some evidence of small firm effect is found in this study, but price overreactions are more apparent with large size portfolios. Apart from size, asymmetrical investors' response to good news and bad news also drives stock prices to behave differently after experiencing abnormal gains or losses. For winner stocks, larger abnormal gains on day 0 are followed by larger abnormal losses in the subsequent 10‐day period. Whereas for loser stocks, larger abnormal losses are followed by larger but further losses in the test period. Last but not least, symptoms of weekly price seasonally are found amongst the abnormal return patterns in this study.

Builds on the work of Damodaran (1993) and Brisley and Theobald (19967) on measuring the speed with which stock markets convert information into price changes by using a simpler model of the price adjustment coefficient and applying it to 1988‐1966 data from the Hong Kong, US and Japanese markets and the Morgan Stanley Capital International indexes. Explains the methodology and presents the detailed results, which show that the Hong Kong adjustment is similar to the US and Japan for systematic and for all information; although the range of adjustment speeds depends on the sector and composition of the indexes. Makes many comparisons between the three markets and suggests that this method of describing market efficiency could provide a more consistent and objective ranking of worlds capital markets.

Social interaction in comment sections has become a key factor for backers' decision making in crowdfunding platforms. However, current research on the two-way social interaction in crowdfunding is insufficient, and there exist inconsistent conclusions. This study focuses on the social interaction between creators and backers and explores its influence on the successful exit of crowdfunding projects.

The extended Cox model is used for the empirical analysis of 1,988 crowdfunding projects on the Modian (www.modian.com) platform, a crowdfunding platform for cultural and creative projects in China. The two-way social interaction is reflected in comment quantity and sentiment, as well as reply rate.

Results reveal an inverted U-shaped relationship between comment quantity/sentiment and the successful exit of crowdfunding projects. This relationship is strengthened by high reply rate.

This study focuses on comment quantity and sentiment. The inverted U-shaped results reconcile previous conclusions. Replies from creators are regarded as a separate factor, and their moderating role is explained. The study research proves the importance of social interaction in crowdfunding platforms and provides suggestions for backers, creators and platform managers.

Dual Diagnosis Anonymous (DDA) is a peer-led programme developed in the USA, which aims to address mental and addictive disorders in an integrated manner. This study is part of a mixed-methods evaluation of the first DDA pilot in the UK, and the purpose of this study is to explore the impact and mechanism of change of the programme through the perspective of DDA attendees, facilitators and the funding commissioners.

Six DDA members were interviewed three times over a period of 12 months, the facilitators were interviewed twice and the commissioner was interviewed once. The qualitative longitudinal data were analysed using a trajectory thematic analysis.

DDA attendance was perceived to have had a positive impact on five main areas: acceptance of self, of others and from others; social functioning; self-development; recovery progression; and feeling of hope. The possibility of addressing both mental health and addiction at the same time was a key factor in the recovery process. The facilitators observed that DDA had contributed to integrate members into employment and education, while the commissioner stressed the importance of joint commissioning and sustainability.

The longitudinal approach provided a unique insight into the recovery process of DDA members. Being able to address the mental health as well as the substance use problems was considered to be a fundamental strength of DDA in comparison to the single purpose peer-support fellowships.

Suicide is a tragic cause of death and causes considerable distress for families, carers and healthcare professionals. Thankfully, suicide rates in older people in the UK have steadily declined for both men and women since the mid‐1980s. An understanding of the clinical and demographic characteristics of both completed suicide and non‐fatal self‐harm in older people is important in informing the development of preventative strategies to sustain this decline. Non‐fatal self‐harm in older people is relatively uncommon compared with younger age groups, but research indicates that self‐harm among older people is frequently a failed attempt at suicide. Thus, the important factors associated with self‐harm in this age group are similar to those linked with completed suicide, particularly high rates of clinical depression, poor physical health and social isolation. Unfortunately, there is also a high rate of subsequent completed suicide. For this reason, self‐harm in later life needs to be taken very seriously and a careful assessment of risk and need by a specialist in older people's mental health should be conducted. The identification and appropriate management of older people with depression in the community and general hospitals is a key area for the prevention of self‐harm and suicide in this age group and requires further attention, particularly with targeted support programmes for those at high risk.

This research aims to gain a holistic understanding of how video conferencing (VC) apps' media characteristics influence individuals' perceptions of VC apps and, ultimately, their use and continued use in professional settings.

A conceptual research model is developed by integrating constructs from media synchronicity theory (MST), social presence theory and the unified theory of acceptance and use of technology (UTAUT2) model, as well as ubiquity, technicality and perceived fees. Structural equation modeling (SEM) is used to empirically test the conceptual model using data collected from 252 working professionals from the European Union.

The results reveal that while performance expectancy (PE) and facilitating conditions (FC) are fundamental to VC app use, these factors alone do not explain the use and continuing use of VC apps in the professional context. Media characteristics that include synchronicity, social presence, and ubiquity are equally crucial to professionals using VC apps. It also confirms the moderating effect of convergence on the relationship between synchronicity and PE and the moderating effect of technicality and perceived fees on the relationship between ubiquity and FC.

For researchers, the study offers insights into the extent to which technological and socially derived characteristics of VC apps influence the routine tasks undertaken by professionals in virtual work settings. For practitioners, recommendations pivotal to the use of VC apps are presented to promote higher acceptance and improved well-being of the professional workforce.

Creative performance relies on the capability of developing and presenting an original concept or idea, and the collaborative production of creative content which enhances feeling of connection with others and formation of strong community. The purpose of this paper is to apply the theory of work performance containing four dimensions (capacity, opportunities, willingness, and performance) to investigate how the capabilities of social network sites enhance user creative performance through collective social capital and information capital (opportunities) for and individual habit of use (willingness) of the user to engage in social learning process.

Many measurement items are adapted from the literature, except those measuring the constructs of social media capabilities (i.e. transmission velocity (TV), parallelism, symbol sets, rehearsability, and reprocessability) and user creative performance. The study uses survey method to collect data from social media network (SMN) users in Taiwan. Facebook is chosen as the source because it is the most prevalent and sophisticated social media platform that provides a home for users to interact and communicate. Structural equation modeling with partial least square is used to analyze the usable data collected from 533 Facebook users.

The results show that the constructs are significantly and positively correlated, meaning that social media capabilities enable social capital, information capital, and habit of use to improve user creative performance in SMNs. Three out of five social media capabilities (i.e. TV, parallelism, and rehearsability) are identified as the key enablers.

Because of the sampled surveyed subjects and the single research method, there are some limitations in this study. The research results may lack generalizability that should be taken into account when they are interpreted. The authors encourage researchers to test the proposed theoretical model further with additional subjects, variables, and linkages.

The findings of this research shed light for managers of SMN platforms on how to manage the platforms more effectively. A healthy SMN platform must implement at least these three media capabilities: the functions of news feed (i.e. TV), chat (i.e. parallelism), edit (i.e. rehearsability), in order to sustain its service.

This study confirmed that user creative performance can be increased in various ways through social capital, information capital, and habit of use. Company management should use SMNs (e.g. Facebook or Twitter) to enable employees to interact and exchange ideas and promote “coopetition” among employees across the company. If the organizational culture supports free expression of ideas and sharing of opinions, the development and robustness of group creativity can be enhanced, leading to higher competitive advantage for a company against its competitors.

Past studies related to individual creativity have mostly discussed it as a personality trait or talent; yet, personality trait or talent is implicit until it is shown by one’s behavior. Thus, for the collective performance of user creativity on SMNs, the authors elicit individual creativity through the creative performance manifested by user behavior. Furthermore, the authors confirm that social capital, information capital, and habit of use are the critical antecedents of user creative performance, and that the five social media capabilities are the enablers of social capital, information capital, and habit of use on SMNs.
