Continuous usage of e-participation: The role of the sense of virtual community     

Mijail Naranjo-Zolotov  Tiago Oliveira  Sven Casteleyn  Zahir Irani 《Government Information Quarterly》2019,36(3):536-545

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

一种基于RFID的化工危险品企业人员定位算法研究     

王晓媛 《洛阳工业高等专科学校学报》2015,(1)

针对化工危险品企业无法全面、及时、准确地掌握厂区内人员实时分布信息,从而间接导致事故发生的问题。采用RFID定位系统,介绍了RFID阅读器拓扑网络定位算法,针对算法不足提出了结合VIRE定位算法的改进方法。通过在阅读器周围部署参考标签和虚拟标签来解决模型中目标标签同时被两个以上的阅读器识读的难题,最后找出目标标签的实时位置坐标。并采用使得定位精度更高的权重因子计算公式解决Ej＝0的问题。实验证明：在复杂环境中与RFID阅读器拓扑定位算法相比改进算法在定位精度上有显著提高。  相似文献

‘I like the sound of that’ – an evaluation of providing audio feedback via the virtual learning environment for summative assessment     

Clare Carruthers  Brenda McCarron  Peter Bolan  Adrian Devine  Una McMahon-Beattie  Amy Burns 《Assessment & Evaluation in Higher Education》2015,40(3):352-370

This study aims to ascertain student and staff attitudes to and perceptions of audio feedback made available via the virtual learning environment (VLE) for summative assessment. Consistent with action research and reflective practice, this study identifies best practice, highlighting issues in relation to implementation with the intention of redesigning activities in the light of the findings. It utilises four case studies where audio feedback was provided to students using the Wimba voice authoring tool within Blackboard Learn+ for various types of summative assessment. The intention was to identify how and in what context audio feedback via the VLE is effective and why. The research was undertaken via a combination of techniques, including a student survey and staff reflective logs. The findings indicate that students liked the convenience, effectiveness, flexibility and personalised nature of this feedback, but raised concerns with some aspects of the technology. This paper also makes practical recommendations for the use of the feedback mechanism, focusing on the most effective use of the digital medium, and highlights directions for future research.  相似文献
