This study examines the performance of a cross-boundary e-government system. It draws from studies in the fields of e-government, collaborative public management, and information system success with a focus on inter-organizational information systems to develop a conceptual framework. This framework includes efficiency, effectiveness, and accountability as key performance measures; identifies technical, managerial, and inter-organizational factors for success; and develops hypotheses accordingly. Empirical investigation utilizes user-level data from an inter-organizational e-government system that provides integrated commerce and industry service. The results underscore the importance of management support, shared goals, and inter-agency trust in improving all three measures of performance. In addition, citizen-centric and innovative organizational culture enhances efficiency and accountability while administrative interdependence impacts effectiveness and accountability. The managerial and theoretical implications of these findings and future research opportunities are also explored. 相似文献

Citizen participation in E-governance is, essentially, a social exchange between individuals and their government through which the citizen creates public value as well as acquires private value. The direct effects of participation antecedents on participation outcomes have been fully examined, but few researchers have investigated the internal mechanism of citizen participation at the level of psychological value perception. The roles of perceived public and private value between the participation antecedents and outcomes remain unclear. Private value merits careful research in particular as the E-governance environment is being shaped by increasing privatization and continuous IT innovation. Based on the cognitive integration theory and the civic voluntarism model, this paper proposes a theoretical framework to examine the mediating roles of two values. We built a complete research model encompassing ten hypotheses centered on citizen e-participation in the context of green commuting governance. By analyzing survey data on a green commuting platform, we demonstrate the significant mediating effects of these two values and greater effect of private value acquisition on continuous e-participation intentions than public value creation. Our results have important research implications in regards to the roles of perceived values in participation, especially perceived private value. 相似文献

Local governments around the world are increasingly implementing e-participation platforms to involve citizens in consultation and decision-making processes. E-participation platforms usually succeed and produce positive effects in the community when adopted in the long-term scenario. The adoption of those platforms is still a challenge for local governments. The understanding of the factors that influence the continuous intention to use e-participation over time is critical for the design of diffusion and promotion strategies that motivate the citizens to keep using e-participation. This article explores the drivers that predict the post-adoption of e-participation platforms from the perspective of the sense of virtual community theory, that is the degree of affective attachment to a given community mediated by information technology. Specifically, our research model evaluates the association between the sense of virtual community with use behaviour and the continuous intention to use e-participation. Structural equation modelling was used to evaluate the data collected from 370 citizens who experienced an e-participation platform hosted by a European capital city. We found out that the direct association between the sense of virtual community and use was significant. Even though the direct association between the sense of virtual community and the continuous intention was non-significant, the indirect association sense of virtual community to use to continuous intention was statistically significant. This finding may indicate that the use behaviour is triggered by the influence of other members of the community for a short period of time, but it does not persist to influence the continuous intention over time. 相似文献

Cognitive authorities in health education classrooms: A nexus analysis on group-based learning tasks
Socio-technical changes have transformed information practices and challenged conceptions of cognitive authorities, referring to information sources that are deemed credible and legitimate and influence people's thinking. Cognitive authorities in group-based knowledge-construction projects in health education lessons were explored in this study. Nexus analysis was used to analyze participant interviews and video-observed social actions in three secondary school health-education classrooms (Grades 8–9) in Finland. The findings show how group-based projects employing multiple information sources offer opportunities for the distribution and co-construction of cognitive authorities. However, explicit negotiations on the authority of sources were rare. Cognitive authorities appeared as contextual and situational but also guided by broader discourses circulating in the scene of action. By embedding information literacy instruction throughout the curriculum, information professionals and teachers can support young learners to recognize relevant authorities in different spheres of knowledge and to become competent users of health information. 相似文献

Despite the widespread application of technology in the 21st century, making informed decisions regarding its acceptance in organisations is a function of several factors, particularly in developing countries, due to factors such as rising cost of the information technology infrastructure and low technological exposure. A model that incorporated perceived ease of use (PEOU) and e-Skills to examine librarians' intention for actual library technology acceptance was tested. The correlational research design, along with a multistage sampling procedure, was applied to select samples to reduce the sample to a manageable proportion. Professional librarians and library officers in four university libraries provided the data for the study. Results showed that e-Skill is the model's strongest determinant of technology acceptance intention among librarians. Also, PEOU will significantly moderate librarians' intention towards library technology acceptance when e-Skills are insufficient. From these outcomes, the understanding of the determinants of behavioural intention captured in the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAT) is extended and refined. 相似文献

Library instruction often involves one-shot sessions where librarians interact with students for a short period of time and are then left wondering what the students thought of the session and if students perceive the session as helpful for their course work. Using two surveys to gather data, this study compared student perceptions of a redesigned library curriculum and of their own information literacy skills immediately after attending a library workshop and six weeks later after completing a research paper. The findings indicate that the library workshop is meeting student needs and has a lasting effect. Additionally, the researchers found that students were better able to articulate gaps in their own knowledge after having the opportunity to apply their skills to a research assignment. The researchers recommend that librarians using surveys to inform one-shot curricular changes gather data after students have applied the skills and knowledge gained in the instruction session. 相似文献

When myths become canonical beliefs within a professional culture, they can have a profound impact on professional practice. In this paper we identify as a pernicious educational myth the belief that the ability to teach well is a naturally occurring innate talent or skill. The first two sections of the paper aim to demonstrate (i) that the concept of the naturally gifted teacher is a myth based on factually incorrect assumptions about expertise development and (ii) that this myth has several major negative implications for professional practices around teaching in academic libraries. We then we draw on the education literature to offer an alternative model for the cultivation of teaching excellence, an instructional design/action research framework that prioritizes ‘deliberative’ practice over innate talent. We close with suggestions for how academic librarians and library administrators can implement this framework within their institutions. 相似文献

To determine the nature and extent of the emerging field of “health law” scholarship in China, we retrieved 2956 publications about various aspects of health law published up through 2014 in 268 journals from the “Chinese Social Science Citation Index” and from the list of Chinese “Core Journals” maintained by the Peking University Library. By bibliometric analysis, we observed some interesting results which were different from our expectations. The collaboration network among Chinese health law (CHL) authors was relatively small, loose, unstable and early in its development. Kan Tian and Lixin Yang were leading authors, Renmin University of China was the primary institution, and Beijing was the predominant region studying Chinese health law (CHL). Kan Tian ranked 1st in the collaboration network and Lixin Yang published the most number of articles on CHL. Comprehensive universities made up the majority of institutions studying CHL, while medical colleges did not focus on health law research, possibly due to medical schools focusing mainly on clinical education and not attaching as much importance to social and humanistic aspects of medicine. Food safety, health administration, and the general principles of civil law were the main areas of focus in CHL research, which is basically in line with what we expected. 相似文献
