This paper aims to explore the pattern and significance of cross‐organizational ties in an emergent professional field, web production in UK higher education.

The research is based on in‐depth interviews with 21 practitioners and analysis of activity in cross‐organizational spaces, such as an online community and a series of annual practitioner conferences on the web in HE (1997).

The cross‐organizational spaces have support and symbolic roles as well as informational ones. They have overlapping but different membership and agendas. Key factors that govern individual participation and so the shape of cross‐organizational spaces are differential involvement in technical innovation, degree of organizational embedding or marginality, differences in organizational position and role, orientation towards centralization or decentralization and orientation towards marketing or IT. There is some sense of occupational community among web managers, but within that also diversity and a significant fracture line between marketing and IT perspectives on the role. This may explain the lack of formal professionalization. As a more natural boundary practice between organizations than marketing, IT has more public visibility, possibly influencing the course jurisdictional struggles over who should control the web.

Most studies of knowledge sharing have focussed on the factors which influence it within an organization, yet cross‐organizational sharing is also of importance, even for established professions as the boundaries of organizations become more open. For new occupations cross‐organizational ties may be a critical resource, and not only for sharing information or support, but for making sense of what the job is about at the deepest level. The research is also original in analysing a relatively little researched occupational group, those producing web sites for a living. It will be relevant to those interested in online and people centered information seeking, in professionalization and occupational identity.

The purpose of this paper is to investigate the cross-effects of on-site sponsorship on online sponsorship effectiveness in communities. The research evaluates how members’ commitment to a sports-oriented community and attitude to brands providing sponsorship developed through sponsorship on-site, and sponsor-community fit, influence the effectiveness of online sponsorship measured as the intention to purchase the same brands online through sponsoring banners displayed on the community web site.

Data were collected through a web-survey from a self-selected sample of 272 respondents belonging to non-professional sports communities. By drawing on the principal tenets of the theory of reasoned action, the authors developed a theoretical framework and tested it through a structural equation model to evaluate the role of attitude to sponsor brands developed through sponsorship on-site, and its antecedents, on the intention to purchase the same brands online through sponsoring banners exposed on the community web site.

The attitude to sponsor brands developed through sponsorship on-site affects the intention to make online purchases of the same brands through sponsoring banners exposed on the web sites of non-professional communities. On the other hand, antecedents of sponsorship on-site, that is, sponsor-community fit and commitment to the community, affect the intention to purchase the same brands online through sponsor banners displayed on the community web site, with attitude playing a different mediating role.

The research contributes to sponsorship literature by establishing the existence of cross-effects of on-site sponsorship on online sponsorship effectiveness and providing insights into the central role of commitment and attitude developed on-site. Managerially, non-professional communities emerge as attractive targets for multiple sponsorship investment owing to their on-site and online social interaction that offers managers an opportunity to exploit sponsorship cross-effects.

The study contributes to the scant body of knowledge on the cross-effects of on-site sponsorship on online sponsorship and provides insights into the importance of communities as a beneficial target of sponsorship investment.

A layered approach for identifying communities in the Web is presented and explored by applying the flake exact community identification algorithm to the UK academic Web. Although community or topic identification is a common task in information retrieval, a new perspective is developed by: the application of alternative document models, shifting the focus from individual pages to aggregated collections based upon Web directories, domains and entire sites; the removal of internal site links; and the adaptation of a new fast algorithm to allow fully‐automated community identification using all possible single starting points. The overall topology of the graphs in the three least‐aggregated layers was first investigated and found to include a large number of isolated points but, surprisingly, with most of the remainder being in one huge connected component, exact proportions varying by layer. The community identification process then found that the number of communities far exceeded the number of topological components, indicating that community identification is a potentially useful technique, even with random starting points. Both the number and size of communities identified was dependent on the parameter of the algorithm, with very different results being obtained in each case. In conclusion, the UK academic Web is embedded with layers of non‐trivial communities and, if it is not unique in this, then there is the promise of improved results for information retrieval algorithms that can exploit this additional structure, and the application of the technique directly to partially automate Web metrics tasks such as that of finding all pages related to a given subject hosted by a single country's universities.

The aim of this study is to investigate the effects of different virtual product experiences (VPEs, interpersonal and machine) on sense of virtual community (SOVC) for consumers. Furthermore, parasocial interaction (PSI) and the sequence of VPEs likely moderate the relationship between different combinations of VPEs and SOVC.

The study employed a factorial online experimental design: 8 (combinations of VPEs, between subjects) x 2 (sequences of VPEs, between subjects). Participants were randomly assigned to the 16 groups.

The results show that with a high degree of PSI, the “escapism + social” VPEs group has the greatest beneficial effects on SOVC, whereas with a low degree of PSI, the “aesthetics + information” VPEs group has the greatest beneficial effects on SOVC. Besides, in VPES sequence 1 (interpersonal → machine), the “escapism + social” VPEs group has a greater effect on SOVC, whereas in sequence 2 (machine → interpersonal), there was no statistically significant difference for VPEs combinations relative to SOVC.

This study determines that consumers with different degrees of PSI differ from one another regarding their interactions with web sites and communities. Therefore, the characteristics of PSI provide manufacturers with various marketing strategies for interaction. The combinations and sequences of interpersonal and machine VPEs in this study can provide manufacturers with suggestions for appropriate online shopping web site design.

Although the importance of these virtual experiences is continuously increasing, there is still a lack of studies that empirically analyze from the combinations of machine interaction and interpersonal interaction of VPEs of the effects on consumer behavior.

In any critical system, high‐availability of software components like web services has so far been achieved through replication. Three replication strategies known as active, passive, and hybrid, describe for example how many replicas are needed, where to locate replicas, and how replicas interact with the original web service and among themselves if needed. The purpose of this paper is to show how replicates could be substituted with components that are similarly functional to the component that needs back‐up in case of failure.

After examination of the different existing replication strategies, it was decided to test the suitability of the proposed web services high‐availability approach based on communities for each strategy. To this end, the specification of web services using two behaviors, namely control and operational, was deemed appropriate.

The active replication strategy is the only strategy that could support the development of a web services high‐availability approach based on communities of web services.

The proposed approach has been validated in practice by deploying a JXTA‐based testbed. The experimental work has implemented the active replication strategy.

Software component high‐availability could be achieved by components that are similarly functional to this component, which permits the common limitations of existing replication strategies to be addressed.

The purpose of this paper is to propose an in-depth analysis of online communities of practice that support the innovative development of web applications. The analysis is aimed at understanding the preeminent characteristics of communities of practice that can favour the process of innovation (conceptualisation and realization of a web application) and if these characteristics differ in the diverse phases of a software development project (requirement specification, design, implementation and verification).

The authors adopted a multiple case study research design, selected 29 communities of practice related to the development of web applications and classified them recognizing the different practices that refer to the different phases of the innovation process of web-applications software development. Finally, the authors focussed on seven communities comparing five important dimensions for each one.

The results of the empirical analysis show that the best practices are different, considering the different phases of the project, and that these practices can be strategies directed at members to attract them and also, strategies directed at the community to permit collaboration.

The paper proposes an important and new insight into the management of virtual communities of practice (VCoP). The authors supposed that the ways to manage a VCoP could depend on project phases. In particular, the management practices of community should differ according to the different project phases, i.e. requirements specification, design, implementation and verification of the software. Literature in this sense presented only research focussed on the different effects of virtualness on teams depending on the length of team duration and on communication efforts.

The purpose of this paper is to improve the general operationalization of an “active patient,” by examining the specific activities and skills expected of active patients.

Expected activities and necessary skills were studied through a qualitative case study into the development and use of an assistive technology (i.e. web site) aimed at stimulating active patient-ship. Interviews, observations and document analysis were used to capture and explore designers’ inscribing practices and their consequences regarding expected competences and activities of patients using the web site.

Designers inscribed two “co-design roles” that active patients were expected to perform on the web site (co-designing their own healthcare and co-designing the healthcare of peers), for which at least eight different competencies were needed. The absence of skills or facilities to apply these skills resulted in incomplete use, a different use than intended by designers and non-use of the web site.

Technological choices and inscribing processes determine who is able or facilitated to become active and who is not. Due to inscribed co-design roles, it also influences the extent to which already active peers are able to perform health-related activities. Different users with different conditions should be taken into account in the design as specific group characteristics can influence level of individual activity.

This study is, as far as the authors know, the first that examines the “active patient” concept by studying an assistive technology and using scripting literature, resulting in an improved understanding of what it means to become “active” in terms of skills and activities.

By expanding the technology acceptance model, the purpose of this paper is to provide a research model to examine the impact of online (information quality, system quality and service quality) and offline (offline activities) features on the sustainability of virtual communities. Design/methodology/approach – Based on a survey of 165 community members, the paper uses structural equation modeling approach to investigate the research model.

The findings indicate that perceived of usefulness, perceived ease of use and offline activities are determinants of sustainability of virtual communities. In addition, information quality affects perceived usefulness, while system‐quality and service quality influence both perceived ease of use and perceived usefulness of virtual communities.

Since this study only considered non‐profit virtual communities, it is unclear whether these analytical results can be generalized to other virtual communities. Further research can apply this research model to examine profit‐oriented virtual communities, such as eBay.com.tw or brand communities.

To sustain a successful virtual community, attention must be paid to enhance both online and offline interactions, including content management, specific sets of web site functions and offline communication. Virtual community providers can apply the findings of this study to focus on the determinants of success for their virtual communities.

Theoretically, while drawing upon the extended TAM, this paper provides a model that is capable of understanding the determinants of sustainability of virtual communities. From a managerial perspective, the findings should provide further insight into member behaviors, leading to more effective strategies for expanding the virtual community.

Aims to investigate the way that the semantic web is being used to represent and process social network information.

The Swoogle semantic web search engine was used to construct several large data sets of Resource Description Framework (RDF) documents with social network information that were encoded using the “Friend of a Friend” (FOAF) ontology. The datasets were analyzed to discover how FOAF is being used and investigate the kinds of social networks found on the web.

The FOAF ontology is the most widely used domain ontology on the semantic web. People are using it in an open and extensible manner by defining new classes and properties to use with FOAF.

RDF data was only obtained from public RDF documents published on the web. Some RDF FOAF data may be unavailable because it is behind firewalls, on intranets or stored in private databases. The ways in which the semantic web languages RDF and OWL are being used (and abused) are dynamic and still evolving. A similar study done two years from now may show very different results.

This paper describes how social networks are being encoded and used on the world wide web in the form of RDF documents and the FOAF ontology. It provides data on large social networks as well as insights on how the semantic web is being used in 2005.

Social websites have become a major medium for social interaction. From Facebook to MySpace to emergent sites like Twitter, social websites are increasing exponentially in user numbers and unique visits every day. How do these websites encourage sociability? What features or design practices enable users to socialize with other users? The purpose of this paper is to explore sociability on the social web and details how different social websites encourage their users to interact.

Four social websites (Facebook, MySpace, LinkedIn and Twitter) were examined from a user study perspective. After thoroughly participating on the websites, a series of observations were recorded from each experience. These experiences were then compared to understand the different approaches of each website.

Social websites use a number of different approaches to encourage sociability amongst their users. Facebook promotes privacy and representing “real world” networks in web environment, while MySpace promotes publicity and representing both real world and virtual networks in a web environment. Niche websites like LinkedIn and Twitter focus on more specific aspects of community and technology, respectively.

A comparison of different models of sociability does not yet exist. This study focuses specifically on what makes social websites “social.”
