New service development in e‐government: identifying critical success factors

Purpose – The purpose of this paper is to suggest a model that incorporates critical factors contributing to the success in new service development (NSD) projects in electronic government (e‐government).Design/methodology/approach – After a brief introduction to e‐government and NSD in respect to models for successful implementation, the authors justify and build on the existing literature that advocates the use of critical success factors (CSFs) to study the implementation of these projects. They suggest a model that incorporates the determinants of success or failure for a new service through a set of variables.Findings – This paper proposes a framework, which is believed to help with the empirical research of CSF in NSD. The suggested framework attempts to bring experience in leadership and coordination of work theory and practice together by synthesising the existing literature with real‐life experience.Research limitations/implications – The paper contributes to the e‐government implementation litera...

Cyberbullying-Entrenched or Cyberbully-Free Classrooms? A Class Network and Class Composition Approach

Cyberbullying threatens young peoples well-being. This study is one of the first to examine cyberbullying from a social network perspective. The class-based friendship networks of 103 classes were reconstructed using peer-nomination questionnaires. Closeness centralization and the global clustering coefficient were calculated using social network analysis and subsequently entered into a Poisson-regression. The outcomes of these analyses show that in classes featured by high closeness centralization in the offline and online friendship network, more cyberbullying happens. Additionally, our analyses reveal that in classes featuring a high global clustering coefficient in the online network, less cyberbullying occurs. The composition of the class in terms of gender and ethnicity were not significantly associated with the number of cyberbullying incidents in class.

Bridging the Divide between Virtual and Embodied Spaces: Exploring the Effect of Offline Interactions on the Sociability of Participants of Topic-Specific Online Communities

Our paper focuses on the effect that offline interactions have on the sociability of participants of online communities. We present the findings of a longitudinal study of an invitation-only online community of cigar smokers, tracing the interactions of its participants over a period of eighteen months. We identify the emergence of distinctive patterns of interaction that persist over the course of the study, and explore their effect on the sociability of the participants of the online community. The identified interactions are associated with a mix of behaviors that include play, trading and gifting, and entail the exchange or flow of informational and material objects. Our findings demonstrate that offline interactions play a significant role for the social networking of participants on online communities, and have a positive effect on their online sociability over time. We provide novel insights regarding online participation and offline interactivity, significant for both academics and practitioners.

A Roadmap to the Introduction of Pervasive Information Systems in Healthcare

Pervasive healthcare is an emerging research discipline, which focuses on the development of pervasive and ubiquitous computing technology for healthcare environments. Information and Communication Technologies have dramatically evolved during the last decade, laying a solid foundation for the future generation of Ubiquitous Internet access. As a result, current efforts in research and development in the areas of pervasive healthcare, promote the formation of inter-disciplinary international teams of experts, scientists, researchers and engineers to create a new generation of applications and technologies that will facilitate the fully automated information cyberspace systems. The authors discuss the current state-of-the-art in the world of Telecommunications and Internet Technologies as well as new technological trends in the Internet and Automation Industries, while promoting research and development in the interdisciplinary projects conducted by multinational teams worldwide.

Inter-Social-Networking: Accounting for Multiple Identities

We argue that the current approaches to online social networking give rise to numerous challenges regarding the management of the multiple facets of people’s digital identities within and around social networking sites (SNS). We propose an architecture for enabling people to better manage their SNS identities that is informed by the way the core Internet protocols developed to support interoperation of proprietary network protocols, and based on the idea of Separation of Concerns [1]. This does not require modification of existing services but is predicated on providing a connecting layer over them, both as a mechanism to address problems of privacy and identity, and to create opportunities to open up online social networking to a much richer set of possible interactions and applications.

Decision Making for Content Management Systems: Criteria Identification and Categorisation

The use of content management systems (CMS) has radically changed the way that web sites are deployed. The plethora of such systems however, makes the decision-making process a challenging task since there is no available classification for CMS. Our study attempts to identify distinctive characteristics of CMS in order to classify them in performance categories. The analysis of our study incorporates both quantitative and qualitative research methods for the successful triangulation of the identified results. For the needs of the study we explored 570 CMS and identified 51 criteria, which we ranked into six distinctive categories that describe clearly the issue of CMS selection. The results of our study can represent an invaluable asset for the successful outcome of decision-making regarding CMS selection from an organization or individuals, and a competitive advantage for the use of innovation toolkits such as benchmarking.
