Despite calls for improving current approaches to conceptualizing and measuring the construct of information system use, theoretical advances in this regard are still insufficient. The present paper proposes to expand the focus of existing conceptualizations that exclusively focus on technology interaction behaviors via the construct of IS use-related activity. Based on task-technology fit and activity theory, IS use-related activity is conceptualized as a second-order aggregate construct that comprises both technology interaction behaviors, as well as activities users undertake to adapt the task-technology-individual system. A multiple-indicators and multiple-causes analysis of data collected from 190 users in 21 organizations is found to support the proposed conceptualization.

Despite increased research interest on e-government, the field currently lacks sound theoretical frameworks that can be useful in addressing two key issues concerning the implementation of e-government systems: (1) a better understanding of the factors influencing the adoption of e-government systems, and (2) the integration of various e-government applications. The objective of this paper is to provide a foundation towards the development of a theoretical framework for the implementation of e-government systems via extensive literature review, which resulted in (1) a synthesis of existing empirical findings and theoretical perspectives related to e-government adoption, and (2) development of the premises of a conceptual model that would reflect the multi-level and multi-dimensional nature of e-government systems’ acceptance.
