We theorize about the strategic alignment of computing with organizational mission, using the Commonwealth of Pennsylvania's efforts to pursue digital government initiatives as evidence. To do this we draw on a decade (1995–2004) of changes in Pennsylvania to characterize how a state government shifts from an organizational to an enterprise perspective regarding computing. We document and analyze the strategic and operational aspects of a series of information and communications technology (ICT) planning efforts to highlight the nature and roles of strategic alignment used to achieve this transition. Findings from this analysis mark the importance of combining several approaches to strategic planning regarding the adoption and application of ICT. 相似文献

There is growing interest in the role of emotion when considering communication in the workplace. This work has most often considered workers in front-line service positions in investigations of emotional labor, and human service workers in investigations of empathy and emotional work. In this study, we consider processes of both emotional labor and emotional work in the financial planning profession. Financial planners occupy a role requiring ongoing relationships with clients, conversations about the often emotional topic of money, and a need to manage emotion in a variety of interaction contexts. Thus, from extant theory and literature regarding emotion and communication, we proposed research questions regarding the roles of emotional labor and emotional work in the financial planning profession. These questions were investigated in a web-based survey study of almost 300 professional financial planners and supporting interviews with 14 financial planners. Results indicate support for existing theory on emotional work, extensions to current research regarding emotional labor, and important implications for the role of emotion and communication in a range of professional service roles. 相似文献

This study explores faculty deposits in institutional repositories (IR) within selected disciplines and identifies the diverse navigational paths to IR sites from library Web site homepages. The statistical relationship between the development of an IR and the presence of a Web site dedicated to the reform of traditional scholarly communication is also explored. The implications for the development of institutional repositories are highlighted. 相似文献

We consider some issues of the development of the national information infrastructure in the field of innovation, including a national system of accounting for the results of scientific and technical activities (RSTA) and a national new-generation research computer network (NNGRCN). The current state of the national system of scientific and technical information and its resources for information support of innovation processes are analyzed. In the context of further development of the Commonwealth of Independent States (CIS), we propose a Conception of scientific and technical support for programs and projects of NIS member-states in the field of innovation, making it possible to incorporate the existing innovation-oriented information resources into a joint distributed integrated information system as well as to create new information resources and technologies. 相似文献

This paper explores surviving documentation and what it reveals about the underlying social structure and relations in a historic time and place. The mid-nineteenth century is chosen as a period prior to modern bureaucracies so that documents are not found in defining filing systems. Some six hundred documents are studied individually and characterized collectively. They are examined not to tell a story, however, but for evidence of their creation and maintenance and of their physical types, functional characteristics, and relations between authors and recipients. The study reveals the fruitfulness of such an orientation to documents, which complements traditional historical uses that emphasize document content. 相似文献
