Social networking sites have in recent years become an increasingly popular avenue for young people to express and to share their thoughts, views, and emotions. When young people are emotionally distressed for instance, instead of the traditional channel of consulting friends, parents or specialists, social networking blogs may provide a channel to share and release their emotions and intentions. The objective of the paper is to explore the use of text mining and data warehousing technologies to identify and monitor bloggers who are depressed and may be at risk of suicide, self harm or harming others.

The paper first provides a literature review on relevant work in affective and emotional content text mining and relevant suicide research. An algorithm based on a weighted dictionary text search algorithm was developed to identify at risk bloggers to illustrate the viability of the system. An example that compares the percentage of at‐risk bloggers of three different countries – Australia, the UK and New Zealand‐– from a sample blog population is provided.

The results show that it is possible to use text mining technologies to identify depressed bloggers. However, there is a need for future research to improve identification and remove false alarms.

The ability to identify at‐risk bloggers and to provide appropriate interventions could be critical in avoiding tragic consequences. Such a system could provide an e‐monitoring service for various social agencies to engage with potentially at‐risk bloggers.

The current research represents pioneer work in monitoring depression risk in weblogs – research on monitoring at‐risk bloggers is rather limited.

The aim of this research is to identify users' perceived affordances and explore how they influence the acceptance of an e‐reader device collaborative learning system.

The paper reports on two studies conducted to identify and explore perceived affordances. The first study enabled four users to experience a collaborative problem‐solving task to elicit perceived affordances. The second study developed and used a survey instrument based on a modified technology acceptance model with 54 participants to investigate the influences of the affordances on users' acceptance using the partial least square technique.

Five major affordance factors were found to be significantly influencing users' acceptance of the proposed system. These affordance factors are: mobility affordance, support affordance, connectivity affordance, immediacy affordance, and collaborative affordance. Surprisingly, sustainability affordance was found to have limited influence on the acceptance of the proposed system.

The findings can be applied to other e‐reader devices with features similar to iLiad such as Sony PRS, Kobo, Nook, PocketBook and Viewsonic. Prototyping is a critical design process which aims to elicit user experiences. The research implies that the prototype system is capable of generating perceived affordances that are useful for e‐reader device development in order to enhance acceptance. The convenience sample used in the survey is biased towards male participants. As male and female users perceive information and communications technologies (ICT) differently, caution should be taken when applying the findings to the general population.

Practitioners should focus on utilising the support affordance of the system and identifying clear learning goals with the help of collaborative affordance as the learning pedagogy. System designers should focus on creating a good range of visible support affordances that are intuitive, while enhancing or complementing the collaborative learning affordances. The design of an integrated chat application is important as it lays the foundation for ensuring that collaborative learning with e‐reader devices is possible.

E‐reader devices have not been studied extensively as collaborative learning systems. This research is believed to be the first to integrate and explore the use of an e‐reader device in a collaborative learning environment. This study introduces the concept of composite affordance with a modified technology acceptance model for investigating users' acceptance of an e‐reader device as a collaborative learning system.

The purpose of this study is to explore a consumption values model for Islamic mobile banking acceptance and to identify any differences in perceived consumption values between Muslims and non-Muslims towards the use of Islamic mobile banking services.

Using an online survey method, a sample of 183 was collected and the partial least squares (PLS) method was used to evaluate the model and validate hypothesis, as it is ideal for assessing both the psychometric properties of all scales and, subsequently, to test the structural relationships proposed in the model.

Empirical results via the PLS method demonstrates that the result satisfactorily explains the adoption of Islamic mobile banking and further demonstrates the use of the consumption values model as an alternate approach for technology adoption. The consumption values model approach appears to have a stronger fit for Muslims than non-Muslims with 66.6 per cent of the variance explained and a goodness-of-fit index of 0.724. The conditional factors are important in the non-Muslims compared to Muslims. Muslims seem to value emotional factors more than non-Muslims.

The current research findings represent mainly university students with some exposure to Islamic mobile banking experience and familiarity with mobile technology. Indeed, the samples were taken from Malaysia, an Islamic country that has a diverse ethnic and cultural background. Hence, the result may not apply to other Islamic countries, e.g. Arabic countries due to the cultural background differences. Future researchers could overcome the limits of generalisability by increasing sample coverage.

This research finding is useful as the comparison is made between Muslim and non-Muslim consumers which help practitioners and researchers to better understand the different adoption characteristics and advance insights on how to promote such a technological service for everyday banking needs especially to different segments of the community. In developing Islamic mobile banking interactions, designers should look beyond the system’s ease of use and take advantage of the different consumption values to include personalisation in the service design through automatically recognising Muslim customers and non-Muslim customers during system use.

The study contributed to the theory of consumption values model in technology adoption and demonstrated the model is capable of explaining the functional, emotional, epistemic, conditional and social values on consumers in their adoption intention. This research provides empirical findings not reported in previous studies due to the overly represented technology acceptance model approach.
