The who and the what of usage of two cancer online communities

The explosion of use of Internet-based communication for health requires attention to the ways survivors of specific diseases and those close to them participate in using resources. This research focuses on two cancer groups – breast and prostate – and how they use WebMD asynchronous bulletin boards. Four hundred and eighty two messages were coded for communicator (survivors, spouses, others) and content of messages. Most common communicators were survivors, but the two groups differed in percentages of communicator. Of four main categories of content – medical/treatment, intimacy/sexuality, emotional expression, and support – most common were support and medical/treatment. The groups differed significantly on those four categories, with breast cancer more support-dominated and prostate more medical/treatment-dominated and more intimacy/sexuality messages. There were no group differences in emotional-toned vs. social support seeking vs. providing support, or positive vs. negative emotions expressed. Generally, there was considerable commonality, and the differences found primarily supported gender-specific notions of communication and need.     

The lesbian,gay, bisexual and transgender community online: discussions of bullying and self-disclosure in YouTube videos

Computer-mediated communication has become a popular platform for identity construction and experimentation as well as social interaction for those who identify as lesbian, gay, bisexual or transgender (LGBT). The creation of user-generated videos has allowed content creators to share experiences on LGBT topics. With bullying becoming more common amongst LGBT youth, it is important to obtain a greater understanding of this phenomenon. In our study, we report on the analysis of 151 YouTube videos which were identified as having LGBT- and bullying-related content. The analysis reveals how content creators openly disclose personal information about themselves and their experiences in a non-anonymous rhetoric with an unknown public. These disclosures could indicate a desire to seek friendship, support and provide empathy.     

Predicting continuance in online communities: model development and empirical test

Popular interest in online communities has grown rapidly in recent years as a result of the widespread diffusion of Web 2.0 applications. However, the full values and potential of online communities cannot be realised without users' ongoing participation. Thus, this study aims at developing and empirically testing a research model to examine users' continuance intention to participate in an online community based on an extended information systems (IS) continuance model. Specifically, entertainment value and affective commitment are included in the IS continuance model and empirically examined in the context of online communities. A total of 240 returns collected from an online survey, which was conducted among users of a website bulletin board-based community in China, were analysed using partial least squares. The results reveal that users' continuance intention to participate in an online community is determined by both satisfaction and affective commitment. Satisfaction and affective commitment are, in turn, influenced by positive disconfirmations of purposive and entertainment values. The findings of this study contribute not only to theory building in online community continuance but also inform online community moderators in their effort to develop strategies for retaining their users.     

Building more resilient communities with a wildfire preparedness drill in the U.S.: Individual and community influences and communication practices

When a wildfire strikes, it impacts entire communities. Yet it can be challenging to get communities to take the lead in becoming more prepared, and thus build lasting resilience. Guided by theoretical preparedness models, and using a case study design, this study examines the planning, execution, and subsequent sensemaking around one of the first community-led wildfire evacuation drills in the United States. Findings illustrate the interplay between individual preparedness, communication, and community involvement as the neighbourhood studied conducted their drill in partnership with multiple emergency response organizations. Our model explains 39% of the variance in individuals' preparedness, finding that people with higher self-efficacy, more involved with the community, and who felt strong social norms around preparedness had more items prepared for a wildfire. The community's desire to share the preparedness organizing process with external audiences is a unique and important contribution in understanding how communication can be used to sustain community resilience.     

Examination of community identification and interpersonal trust on continuous use intention: Evidence from experienced online community members

Members’ continued intention to use a community service is rooted in social identity. Past research has examined social identity but ignored the development of interpersonal trust through community identification. Drawing on social identity theory, one can conclude that community identification is the foundation of a member’s continuous use intention through interpersonal trust. Data come from responses to a two-stage survey of experienced members of an online game-based community. The findings support the belief that the identity of the community will strengthen long-term relationships within it. The projection of community identification on continuous use intention is tied to interpersonal trust.     

Learning and self-disclosure behavior on social networking sites: the case of Facebook users

This paper studies Facebook users’ learning-based attitude formation and the relationship between member attitude and self-disclosure. Through the theoretical lens of learning theories, we recognize the key antecedents to member attitude toward a social networking as stemming from classical conditioning, operant conditioning, and social learning-related factors. In addition, we explore the underlying process through which member attitude affects self-disclosure extent and theorize the mediating role of site usage rate on the relationship between attitude and self-disclosure extent. Analysis of 822 survey data results provides strong support for the role of learning theories in explaining Facebook members’ attitude development. The results also confirm a significant, partial mediating effect of site usage rate. A series of post-hoc analyses on gender difference further reveal that attitude formation mechanisms remain constant between male and female Facebook users; gender difference exists on the association between attitude and self-disclosure extent and the association between site usage rate and self-disclosure extent; and the mediating effect of site usage rate exists in male user group only. Our research, therefore, contributes to the literature on social networking sites, as well as providing behavioral analysis useful to the service providers of these sites.

Electronic transformation of government in the U.K.: a research agenda

This paper presents the findings of an exploratory research project into future e-Government (electronic Government) initiatives. The Virtual Institute for Electronic Government Research (VIEGO) project aimed at identifying and further developing the research agenda of e-Government based on a solid practical ground. As such, the paper offers a novel methodology in identifying the road map for future e-Government initiatives based on a series of workshops organised around the U.K. hosting a mixture of stakeholders involving both academics and practitioners. The analysis of the VIEGO workshops depicted that an e-Government research agenda involves a combination of social, technological and organisational issues at both governmental and individual citizen level, ultimately driven by empirical case-based experience and active participation in e-Government processes. Unlike other propositions for the future of e-Government offered in the e-Government literature, it raised research questions not only originated from an analysis of e-Government literature but also on the outcome of brainstorming, reflections and contemplations throughout the duration of the project.     

IGBA and the national geochemical data bank in the U.K.: Design and systems

The evolution of geochemical data banking in the UK is summarized, and the relation of the IGBA data base to the National Geochemical Data Bank explained. The method of collecting data into IGBA is through authors at the time they are preparing for publication, papers carrying the geochemical information. The data are collected in fixed card image format in hard copy or machine-readable form. The format permits storage and retrieval not only of chemically determined major and trace element contents per sample, but also of the name, sample number, locality, mineral assemblage, petrography, texture, mode of occurrence, degree of alteration, precision of mineralogical and petrographic information, age, isotopic data, analytical procedure and quality control, and if appropriate oceanographic information for ship-borne collected samples. The path of data from the research operator's file to retrievable national data base is described, and an example given.     

Recent history and imminent prospects for CAL in the U.K.

In this paper the author examines the events leading up to the National Development Programme for Computer Assisted Learning (1973–1977), the achievements of that programme and of the microelectronics education programmes initiated in 1979/80. Looking forward, he emphasises the need for continuing development programmes if education is to meet the needs of students in a rapidly changing world. New developments such as interactive video and expert systems offer new educational possibilities, but the technology itself is less significant than the consideration of the type of educational system in which it should be applied.     

Exploring the effect of user engagement in online brand communities: Evidence from Twitter

Social media such as forums, blogs and microblogs has been increasingly used for public information sharing and opinions exchange nowadays. It has changed the way how online community interacts and somehow has led to a new trend of engagement for online retailers especially on microblogging websites such as Twitter. In this study, we investigated the impact of online retailers' engagement with the online brand communities on users' perception of brand image and service. Firstly, we analysed the overall sentiment trends of different brands and the patterns of engagement between companies and customers using the collected tweets posted on a popular social media platform, Twitter. Then, we studied how different types of engagements affect customer sentiments. Our analysis shows that engagement has an effect on sentiments that associate with brand image, perception and customer service of the online retailers. Our findings indicate that the level, length, type and attitude of retailers' engagement with social media users have a significant impact on their sentiments. Based on our results, we derived several important managerial and practical implications.     

The reciprocal effects of social network site use and the disposition for self-disclosure: A longitudinal study

Since the advent of social network sites (SNSs), scholars have critically discussed the psychological and societal implication of online self-disclosure. Does Facebook change our willingness to disclose personal information? The present study proposes that the use of SNSs and the psychological disposition for self-disclosure interact reciprocally: Individuals with a stronger disposition show a higher tendency to use SNSs (selection effect). At the same time, frequent SNS use increases the wish to self-disclose online, because self-disclosing behaviors are reinforced through social capital within the SNS environment (socialization effect). In a longitudinal panel study, 488 users of SNSs were surveyed twice in a 6 months interval. Data were analyzed using structure equation modeling. The proposed reciprocal effects of SNS activities and self-disclosure were supported by the data: The disposition for online self-disclosure had a positive longitudinal effect on SNS use which in turn positively influenced the disposition for online self-disclosure. Both effects were moderated by the amount of social capital users received as a consequence of their SNS use.     

A survey of information technology in the U.K. service sector

Relationships between the use of information technology and organizational variables have been analysed using a sample of 638 business organizations in the service sector in the U.K. Data for the study were collected through a mail survey. Among the results presented here are the variation of the proportions of managers and information workers with size of organization, and the relationship between the use of computers and profitability. Discriminant analysis was used to distinguish between organizations using computers and those not using them. The study shows that organizations using computers tend to have more formality in communications, a higher growth rate and a higher proportion of information workers than organizations not using computers. The variation of computer capacity with size of organization is also examined.     

Participating in civil society: the case of networked communities

A community computer network facilitates civic participation by providing pervasive local resources online and by connecting people to local communication and discussion channels, public and non-profit organization leaders and members, and many other civic resources. We present findings from longitudinal data (two rounds between 2001 and 2002) of a stratified random survey of 100 households in a mature community network, the Blacksburg Electronic Village (BEV). We offer exploratory and confirmatory analyses, including a ‘civic effects’ model, that show demographic characteristics (education, age) and psychological factors (extroversion) explain staying informed, collective efficacy, group membership, activism, and using the Internet for civic and political purposes. The model further explains differences in respondents' involvement in local issues once they go online. Informed activists with multiple group memberships become more involved in local issues once going online, whereas informed non-activists become less involved once online. Our study suggests that in order to play a constructive role in creating a more civil society, community networks should explicitly pursue strategies that encourage community activism. One way to do this, given the strong role of association membership in activism, is for ISPs to offer bundled standard Internet applications at low cost to non-profit community groups (e.g. email for leadership, online discussion for members, web space). Community networks should also promote and support the use by local groups of innovative tools for non-experts, such as easy collaborative web-based tools for information production and collaboration.     

The mediating role of group dynamics in shaping received social support from active and passive use in online health communities

Exchanging social support on online health communities (OHCs) can be beneficial to people's health, but the OHC characteristics that promote environments in which users feel socially supported are understudied. We develop a model that examines the mediating influence of OHC cohesiveness, altruism, and universality on the relationships between active and passive use and received OHC social support. Our findings indicate that social support can be derived from both active and passive use of the OHC. Although active use can directly stimulate received OHC social support, the relationship between passive use and social support is fully mediated by OHC group dynamics.

The integration of a satellite spectral analysis into a heather moorland management model (HMMM): The case of Moidach More,northeast Scotland,U.K.

In this paper, high resolution, remotely-sensed data are investigated as a source of management information for moorland vegetation communities on a hypothetical farm in a marginal farming area of Scotland. A hybrid technique for vegetation mapping is adopted. This involves unsupervised machine classification of spectral variation in digitally enhanced air photographs and satellite imagery, together with visual interpretation of the imagery in both the laboratory and the field. This technique enables relative estimates of annual gross biomass production, for a range of vegetation types, to be obtained. The data are integrated into a simple heather moorland management model (HMMM), to produce potential sheep-stocking capacities under a range of management scenarios, the possible financial implications of these scenarios are also assessed.     

The shaping of I.T. trajectories: evidence from the U.K. public sector

This paper reports upon I.T. initiatives in the U.K. public sector where choices were made, decisions taken, major investment authorised, and new I.T. introduced. The research investigation followed practice over several years in three Police Forces as new information technologies were introduced. We focus on these I.T. trajectories, and in particular the actions, interactions and events within and across groups of people. We argue that practices surrounding I.T. choice are socially shaped. Indeed, the choices and subsequent acquisition can be viewed as part of a process of ongoing configuration. We argue that Social Worlds Theory has much to offer in understanding what happens as I.T. trajectories evolve in organisations. The empirical part of the paper reports upon the findings from a longitudinal, cross-case analysis within the three Police Forces – institutions that are often characterised as bureaucratic in form, and culture. In each case, the I.T. trajectories were followed utilising a variety of qualitative techniques. Drawing upon social worlds theory, and boundary objects, we consider the influence of certain ‘objects’ upon I.T. outcomes, and the way in which other boundary objects become a focus for the construction of apparent facades of formality.     

Knowledge construction in an outsider community: Extending the communities of practice concept

We present an empirical analysis of a web forum in which followers of a health-related community exchange information and opinions in order to pass on and develop relevant knowledge. We analyzed how knowledge construction takes place in such a community that represents an outsider position which is not accepted by majority society. For this purpose we applied the Community of Practice (CoP) concept as a guideline for our analysis and found that many well-known activities of CoPs were true of the Urkost community. The social network analysis findings also supported interpreting this community as a CoP. But we found as well that this community had a variety of structural characteristics that the CoP literature deals with insufficiently. We identified the structure of goals, roles, and communication as relevant features that are typical of this outsider CoP. For example, the attitude of the core members towards people of a ‘different faith’ was characterized by strong hostility and rejection. These features provided an effective basis for the development and maintenance of a shared identity in the community. Our findings are discussed against the background of the necessity for further development of the CoP concept.
