Social media monitoring is gradually becoming a common practice in public organizations in the Netherlands. The main purposes of social media monitoring are strategic control and responsiveness. Social media monitoring poses normative questions in terms of transparency, accountability and privacy. We investigate practices of social media monitoring in four Dutch public organizations. Policy departments seem to be more strongly orientated towards monitoring, whereas organizations involved in policy implementation seem to be more inclined to progress to webcare. The paper argues for more transparency on social media monitoring.  相似文献

The outcomes of public libraries as perceived by individuals in the major areas of their lives are analyzed and the benefits as outcome types are systematized. The data are based on a representative sample of 1000 Finnish adults, ranging in age from 15 to 79. The results give a systematic account of the benefits in 22 areas of life that adults derive from using public libraries. These 22 benefits were reduced by factor analysis into three major outcome types: benefits in everyday activities, cultural interests, and career. The association of these outcome types with gender, educational levels, and age is also explored.  相似文献

Large scale open-source library automation systems can increase efficiencies in bibliographic production. The implementation of such a system, Evergreen, was examined in order to ascertain whether it facilitated detection and use of library collections in Indiana public libraries. Three hundred forty-nine participants recruited from nine public libraries completed user surveys. Additionally, library server data about interlibrary loan (ILL) statistics were collected from participating libraries on a monthly basis. The self-reported user survey included questions about patron history at local public libraries, use of the previous Online Public Access Catalogs (OPACs), and use of the Evergreen OPAC for finding and accessing multiple library collections since library users could directly request interlibrary loans via the Evergreen OPAC. The findings indicate that the implementation of the Indiana Evergreen system received moderately positive ratings from the participants; the positive evaluation was primarily related to the use of the ILL function. The ILL service satisfied the participants' needs and motivated them to use the Evergreen OPAC. Benefits for Evergreen users were confirmed.  相似文献

E-Government initiatives of varying scope and complexity have been implemented at the municipal and other levels of government throughout the world. These projects have been chronicled in both academic and practitioner journals and the proceedings of various E-Government conferences. As a consequence of this growing body of data, it is now possible to look across the experiences of numerous governments to understand if there are common issues that may impact the probability of success of E-Government programs. This paper examines the literature to search for critical planning and implementation issues that have had significant effects upon the success of E-Government initiatives. A conceptual framework is proposed which contributes to the theoretical understanding of E-Government initiative planning and implementation, and may inform practitioner success with new E-Government initiatives.  相似文献

This article explores how an alternative multichannel management strategy can improve the way governments and citizens interact. Improvement is necessary because, based on empirical data from various sources, the conclusion can be drawn that there is a gap between the communication channels governments prefer and those that citizens prefer. Governments may be too much guided by rational arguments like the cost efficiency of channels while citizens may choose channels depending on, e.g., task characteristics, personal characteristics or situational factors. In order to close the existing gap and to increase understanding about how different channel types may be positioned in multichannel management, this article proposes an alternative multichannel management strategy that takes both the citizen’s and the government’s perspective into account. This strategy is based on differences in channel types and channel modes via which governments and citizens interact.  相似文献

In this paper, we illustrate the development of a realistic simulation of a humanoid robot model in a virtual environment using USARSim (Urban Search and Rescue Simulator). USARSim provides an accurate 3D simulation of a virtual environment with a detailed rendering and a realistic physics. Moreover, USARSim allows users to observe the virtual environment from different views. One of these is the egocentric view, which can simulate the camera mounted on the robot. The small humanoid robot presented in this work is Robovie-M, developed by VStone Ltd. (Japan). This robot is used by our team Artisti in the RobotCup soccer competitions.Reported experiments compare the behaviors of a real robot and of its virtual model, when controlled by the same control software to asses the possibility to faithfully simulate a robot with 22 degrees of freedom in USARSim. Moreover, we discuss the possibility to close the control loop of the robot in simulation, by simulating also the main robot sensor, i.e. the camera.The experiments show that USARSim, despite being a simple simulator based on a low cost computer game, provides an accurate enough simulation of the physics and a realistic rendering of the 3D scene enabling a faithful simulation of a small humanoid robot at low cost. Thus, one can entirely test the robot software modules in the simulation (namely: the motion control modules, the vision system modules and, by closing the robot control loop in simulation, the behavior and behavior-selection modules).  相似文献

Research has identified numerous factors that influence initial technology adoption decisions. However, extant studies consider beliefs to be static rather than dynamic over the adoption time-span. Various models have been employed to identify adoption behavior, pre- and post-adoption, however, there is little research on the dynamics of users’ belief structures over time and the inter-relationships among them. This study aims to investigate the dynamic nature of users’ beliefs and the relationships among their dynamics, i.e., rates of change. We test our research model based on data obtained at three time-windows using a parallel-growth process model. The results reveal that self-efficacy, usefulness and intention to use are likely to be dynamic, and increase with time. The rate of change in self-efficacy influences the rate of change in usefulness, which in turn affects the rate of change in intention to use. This study theoretically contributes to expanding the extant cross-sectional TAM research to include time-phased TAM studies, and highlights the role of self-efficacy as an important determinant of the dynamics.  相似文献
