Most of the literature on Asynchronous Learning Networks (ALNs) has focused on the pedagogical and technological advantages of this educational delivery mode and the way ALNs can respond to the changing demands and pressures placed on institutions of higher education. However, there are considerable obstacles preventing the widespread implementation of ALNs. These obstacles, and the associated ...

Our paradigm can account for persistent disagreement in con...

Although much contemporary thought considers advanced information technologies as either determinants or enablers of radical organizational change, empirical studies have revealed inconsistent findings to support the deterministic logic implicit in such arguments. This paper reviews the contradictory empirical findings both across studies and within studies, and proposes the use of theories emp...
