Purpose-The purpose of this paper is to help in providing a better understanding on knowledge sharing amongst academics in Higher Education Institutions (HEIs). The aim in this study is realized by profiling existing literature to understand the determinants of knowledge sharing, research trends, theories and future research opportunities. Design/methodology/approach-After carefully examining the extant literature, and by utilising relevant academic-based research databases, a total of 73 papers published in peer-reviewed journals over the last decade were reviewed and analysed using well established systematic literature review methodology. Findings-The adopted systematic review revealed that there is limited contributions in understanding knowledge sharing in HEIs when compared with other sectors. The review provides a number of avenues for future research including technological, cultural, organisational and behavioural aspects at different levels. Practical implications-This study helps in offering a focal point to senior management in HEIs for realising the requirements for developing appropriate strategies and programmes to promote knowledge sharing among academics and consequently enhance their institutions' performance. Originality/value-This study utilised Jesson et al. (2011) in presenting a comprehensive systematic review of knowledge sharing specifically in the context of HEIs. This paper offers some theoretical and practical insights on what contributes towards understating the determinates affecting knowledge sharing practices among academics.

Examining the Influence of Intermediaries in Facilitating E-Government Adoption: An Empirical Investigation AbstractThe adoption and diffusion of electronic government is often impeded by many social and individual factors relating to citizens. In this respect, intermediaries have emerged as a new model for delivering e-government services to overcome such obstacles. This study aims to examine the role of intermediaries in facilitating e-government adoption and diffusion using a survey based empirical study of 502 participants in Madinah City in Saudi Arabia. An extended UTAUT model is used as the theoretical basis utlising trust in the Internet andIntermediaries. The results of this study show that there are significant relationships among the factors that influence intention to use e-government, namely, performance expectancy, effort expectancy, and trust of intermediary. In addition, the findings show that there is a significant relationship between facilitating conditions and usage behaviour proving that intermediaries can influence adoption of e-government services.

With the advancement of disruptive new technologies, there has been a considerable focus on personalisation as an important component in nurturing users' engagement. In the context of smart cities, Internet of Things (IoT) offer a unique opportunity to help empower citizens and improve societies' engagement with their governments at both micro and macro levels. This study aims to examine the role of perceived value of IoT in improving citizens' engagement with public services. A survey of 313 citizens in the UK, engaging in various public services, enabled through IoT, found that the perceived value of IoT is strongly influenced by empowerment, perceived usefulness and privacy related issues resulting in significantly affecting their continuous use intentions. The study offers valuable insights into the importance of perceived value of IoT-enabled services, while at the same time, providing an intersectional perspective of UK citizens towards the use of disruptive new technologies in the public sector.
