Through this article we theorize on the nature and effects of articulation work relative to the take-up and use of information and communications technologies (ICT). Articulation work is “work that enables other work”: that which links people, processes, and technologies within organizations. Articulation work in organizations is both common and too often invisible from a managerial or budgetary perspective. Drawing on data from a study of the introduction and implementation of mobile computing technologies into criminal justice organizations, we highlight two findings: (1) There exist ongoing but unmet articulation needs present in any organization or work system. (2) Articulation is cumulative. We find, that as work becomes more complex (such as adding new work tasks and using new technologies), there is more articulation needed. These findings raise issues with assessing the costs of articulation on individuals, and making arrangements to accommodate explicit and implicit articulation in organizational work, particularly around the take-up and ongoing use of ICT-based systems. 相似文献

The aim of this study was to determine how shaft length affects golf driving performance. A range of drivers with lengths between 1.168 m and 1.270 m, representing lengths close to the 1.219 m limit imposed by R&;A Rules Limited (2008), were assembled and evaluated. Clubhead and ball launch conditions and drive distance and accuracy were determined for seven category 1 golfers (handicaps 0.21 ± 2.41) who performed shots on a purpose-built practice hole. As shaft length increased from 1.168 m to 1.270 m, initial ball velocity increased (+1.8 m/s, P < 0.01). Ball carry (+4.3 m, P = 0.152) also increased, although not significantly so. Furthermore, as shaft length increased, for all club comparisons there was no decrease in accuracy. Ball launch conditions of spin components and launch angle remained unaffected by shaft length. Launch angle increased (0.8°, F = 1.074, P = 0.362) as driver shaft length increased. Our results show that clubhead and ball velocity together with ball carry tended to increase with no loss of accuracy. 相似文献
