Self-efficacy has often been found to play a significant role in healthy dietary behaviours. However, self-efficacy interventions most often consist of intensive interventions. The authors aim to provide more insight into the effect of brief self-efficacy interventions on healthy dietary behaviours.

In the present article, two randomized controlled trials are described. In study 1, a brief self-efficacy intervention with multiple self-efficacy techniques integrated on a flyer is tested, and in study 2, an online brief self-efficacy intervention with a single self-efficacy technique is tested.

The results show that a brief self-efficacy intervention can directly increase vegetable intake and indirectly improve compliance to a diet plan to eat healthier.

These findings suggest that self-efficacy interventions do not always have to be intensive to change dietary behaviours and that brief self-efficacy interventions can also lead to more healthy dietary behaviours.

With the advent of the digital era, the internet has gradually become an essential factor in people’s lives. Its increasing popularity has also caused e-commerce to thrive, and has increased the power of online marketing. In recent years, social commerce has emerged as a new mode of operation which can be distinguished from traditional e-commerce. The paper aims to discuss these issues.

The main purpose of this study is to determine which factors influence a consumer’s behavioral intention in the context of social commerce websites, and to explore overall purchase intentions based on the consumer’s cognitive evaluation. The examination reveals that consumers’ multidimensional perceptions influence both their perceptions of value and their purchase intentions. Other related social awareness factors explored by this study are also shown to influence customers’ purchase intentions.

In summary, the results show that perceived value and social awareness factors influence customers’ purchasing decisions and behavioral intentions for different gender. These findings have significant theoretical and managerial implications.

Social commerce is a subset of e-commerce brought about by the development of social networking. Activities conducted on social networking websites can be considered as a form of social commerce. In Taiwan, social commerce is still in the early stages of development.

The purpose of this paper was to document the food-related environmental beliefs and behaviours of undergraduate university students. More specifically, this research was focussed on determining if environmental sustainability is a consideration in students’ food choices, identifying the specific choices and behaviours adopted to reduce their food-related environmental footprint, and documenting the role of gender and pro-environmental values in these food-related environmental beliefs and behaviours.

This research employed a mixed methods approach, i.e. focus group discussions and a survey, to document the food-related environmental beliefs and behaviours of undergraduate university students. The survey was informed by the results of the focus group discussions, and included standard measures of pro-environmental values and worldview.

Results from focus group discussions revealed a broad array of beliefs and behaviours related to the connection between food, food production and the environment. The survey confirmed these results, but indicated a preference for such actions as recycling and reducing food waste in contrast to such alternatives as reducing meat consumption or avoiding processed foods. These results suggest that educational campaigns could focus on strengthening beliefs about the food-environment connection, as well as help to empower students to take a greater variety of actions to reduce their food-related environmental footprint.

Relatively little attention has been focussed on individual beliefs and practices with respect to achieving more sustainable food consumption, particularly on university and college campuses. The research also represents a departure from previous work in that it utilizes both qualitative and quantitative methods, and takes a broad approach to the food-environment connection.

This study aims to explore switch intention of users’ reading behaviour. Amazon’s 2007 introduction of the Kindle e-book reader launched a new way of reading. The popularity of e-book readers has exploded over past several years. However, the Chinese e-book reader market is still relatively underdeveloped and underexploited when compared with North America or other regions. At the time, it remained unclear whether consumers could be persuaded to abandon conventional printed books for the new device in the Chinese market.

This research has gathered 352 valid questionnaire samples on an Internet survey from the general population. Path analysis was used to investigate the causal relationships which were hypothesized by the structural equation modelling methodology to identify key factors in intention to switch to the e-book reader.

The results indicate that convenience and social influence were found to have a significant effect on consumer switching intention, while switching cost was found to be a significant obstacle to switching. This research also found that convenience of carry and operation of new technological products will lower switching costs. Furthermore, it will lead consumers to have higher switching intention when surrounding friends and families have good experiences and impressions of using new products. Thus, the manufacturers and sellers of e-readers have to consider the easy-to-handle convenient-to-carry while designing products. And the concept of higher social influence and lower switching cost shall lead the marketing strategies.

Recently, some studies address what factors drive users’ willingness to use this new device for reading based on innovation diffusion theory or the technology acceptance model. Few studies have investigated adoption of e-readers for consumers’ perceived innovative and their perception of the costs. Hence, this paper studies the switching intention of readers through dimensions including new product attributes (compatibility, complexity, convenience and e-book content), social influence, price and switching costs and verifies the relationships among these dimensions on Chinese market.
