The rise in popularity of e-books is expected to erode the market share of printed books significantly. However, the demand for e-books has not been as great as initially hoped, especially in developing countries. While it would appear that customer apathy is the foremost obstacle in the growth and use of e-books, more research is necessary in order to understand the broader complexities behind this issue. This study analyses the behavioural intention of students in selected South African tertiary intuitions to use e-books. The study is based on theory rooted in the Unified Theory of Acceptance and Use of Technology (UTAUT) model. Data were collected from 439 participating students from five tertiary institutions in South Africa.The results suggest that, with regard to students in South Africa, performance expectancy, social influence and facilitating conditions are significant antecedents of behavioural intention towards e-book use. Surprisingly, gender differences did not moderate the relationships between the factors examined and behavioural intention, whilst use experience only moderated the relationship between effort expectancy and behavioural intention. The findings of this study do not only provide useful guidelines for the development and promotion of the acceptance of e-books in South Africa, but also make an important contribution to the extant body of literature on e-book acceptance.

This study explores whether investors and analysts might be less attentive at the end of the week for a variety of reasons, including being distracted by the coming weekend or having other information that competes with relevant financial information for their attention. A database containing 22 626 recommendations over the 2000-2011 period was analysed to compare analyst and investor activity on Fridays with their activity during the rest of the week. Analyst activity on Fridays was generally higher than during the week, although it was the highest on Mondays - possibly because they had more time to reflect over the weekend. Analysts issued more positive recommendations on Fridays than during the three preceding days, and issued a higher proportion of negative recommendations on the weekdays with the lowest overall activity. Investors exhibited lower levels of attention on Fridays, and reacted most strongly to analysts' opinions on Tuesdays.

In a global context in which pandemics such as Ebola or the emergence of antibiotic resistance threaten human populations, management theory must offer timely, effective and innovative management of research responses if is to address these it challenges. Certain insights derived from management challenges associated with such extreme cases can be useful for the development of management theory in general. Given the continued presence of these extreme threats, it is clear that capacity to respond satisfactorily is currently lacking. Drawing from Kuhn's theory of paradigms and from epidemiological theory, and extending Schwartz's theory of values configurations, it is argued that values systems constrain research innovation and a theoretical framework is offered for how values transmit into, across and within individuals and groups. It is argued here that values infections can contribute to group conflicts with consequences on the same scale as disease pandemics. It is hoped that this study can contribute to novel understandings of how constraints to innovation (and to real-time research productivity) can be better managed by organisations. Recommendations for management and future research are offered.
