eGov (eGovernment/eGovernance) is a complex endeavor involving many actors, ambitions, and perspectives. The field has, in research and in practice, over the years expanded its focus from service orientation to a comprehensive perspective with the ambition to integrate all of government in coherent action. Comprehensive integration requires a future-oriented perspective so investment is made in robust and flexible solutions meeting not only today's demands but also sustainable to meet those of the future. This paper addresses the use of the sustainability concept in eGov research. We discuss definitions and elements of sustainability and conduct a structured review of eGov literature investigating how various sustainability areas (social, economic, environmental and technical) are addressed. We find 21 overall themes in 94 papers, with the highest number in the “social” category. Two cross-cutting themes to which 21 overall themes relate are also identified; Decision-making and Infrastructure. Findings show that sustainability is mainly addressed narrowly, focusing on projects rather than general issues, and shallowly with a focus on single factors rather than the complex interaction among them, and with little foundation in sustainability theory. The paper contributes with an overview of themes in previous research as well as theory-based input for future research efforts on eGov sustainability, from a dynamic and sociotechnical sustainability perspective.  相似文献

The purpose of this paper is to examine the complex relationships between educational policy and classroom practice. By employing a sociocultural perspective, we examine formulations inscribed in socio-material artifacts about what students should learn and how they should engage with knowledge. We explore how these formulations are mobilized in instructional work and the implications this activity has for student participation. To address this issue, we analyzed video data of how teachers invoke competence aims from the national curriculum in their instructional work in six classrooms. The analytical procedures were derived from interaction analysis. The analysis focuses on how such formulations explicitly mediate social interaction as it unfolds on a micro level. The findings show that competence aims gain different functions as they are mobilized in classroom practice; in other words, they serve different purposes in teachers’ instructional work and anticipate different modes of student participation. In this study, the competence aims were (a) invoked as a source of authority, (b) translated into instructions, and (c) mobilized to obtain social order in the classroom. More rarely, the competence aims were used in meta-level discussions, where they functioned to reach agreements on how to pursue work toward joint goals. We discuss the implications of these ways of invoking competence aims for student participation.
