This study is aimed to explore the social nature of membership in an online community of practice (NETwork, Nurturing Elementary Teachers’ work) whose purpose is to support pre-service and in-service teachers with a collaborative virtual space for learning how to teach. Path analysis was employed to explore the relationships among social constructs: perceived ease of use and usefulness, social ...

E-government adoption is the focus of many research studies. However, few studies have compared the adoption factors to identify the most salient predictors of e-government use. This study compares popular adoption constructs to identify the most influential. A survey was administered to elicit citizen perceptions of e-government services. The results of stepwise regression indicate perceived u...

The challenge of multimedia processing is to provide services that seamlessly integrate text, sound, image, and video information and to do it in a way that preserves the ease of use and interactivity of conventional plain old telephone service (POTS) telephony, irrelevant of the bandwidth or means of access of the connection to the service. To achieve this goal, there are a number of technolog...

The service of E-Commerce logistics enterprises in our country is unable to meet the needs of consumers. The good customer experience can promote consumer s ' perception of the service level of E-Commerce logistics enterprises. The paper elaborates the factors affecting customer experience from website usefulness, website ease of use, transaction costs, customer participation and interactivity,...

Modern information and communication technologies enable service providers to observe and record an individual’s daily actions with relative ease. Given the ability to construct detailed collections of person-specific information, service providers hope to mine for patterns, models, and trends that will assist in the provision of knowledge-dependent services in various environments, including e...

This paper presents three simple techniques for improving network service using relatively unknown features of many existing networks. The resulting system provides greater reliability, enhanced security, and ease of management. First, it addresses the application of IP anycast to provide reliable recursive DNS service. Next, it explains the use of unicast reverse path forwarding and its useful...

Based on the expectancy disconfirmation theory, this study proposes a decomposed technology acceptance model in the context of an e-learning service. In the proposed model, the perceived performance component is decomposed into perceived quality and perceived usability. A sample of 172 respondents took part in this study. The results suggest that users’ continuance intention is determined by sa...

In thispaper we develop a conceptualframework around the attitudes and intentions towards using online information sewice, and we theorise about the differences in relationships between regular information systems and online information services, Specijcally we hypothesize (1) that affect and perceived ease of use are more important than perceived usefulness. and (2) that gender and experìence ...

Abstract—Beyond 3G mobile systems are characterized by the usage of a multitude of different terminals, from high-end devices to miniaturized ubiquitous devices, as well as heterogeneous networks. Complexity for configuration and service provisioning is increased on both terminal and network sides. To ease of the users’ burden, flexible adaptation and personalization support are fundamental req...

Clouds refer to computational resources (in particular, clusters) that are accessible as scalable, on demand, payas-you-go services provided in the Internet. However, clouds are in their infancy and lack a high level abstraction. Specifically, there is no effective discovery and selection service for clusters and offer little to no ease of use for clients. Here we show a technology that exposes...
