The Effect of Members' Satisfaction with a Virtual Community on Member Participation

The authors develop a four-dimensional scale to measure members'satisfaction with virtual communities. The dimensions consist ofmembers' satisfaction with member-member interactions,organizer-member interactions, organizer-community interactions, andthe community's site. Using a sample of 3605 members of a virtualcommunity the authors investigate the effect of each satisfactiondimension on member participation and the moderating effect ofmembership length on the links between the satisfaction dimensions andmember particip ation. The results reveal that satisfaction withmember-member interactions, organizer-member interactions and thecommunity's site have positive effects on member participation.Satisfaction with organizer-community interactions has no effect onmember participation. The findings also show that the linkages betweenthe satisfaction dimensions and member participation are moderated bymembership length.satisfaction;internet;virtual community;consumers;relationship age

Social control in online communities of consumption: a framework for community management

Online communities of consumption (OCCs) represent highly diverse groups of consumers whose interests are not always aligned. Social control in OCCs aims to effectively manage problems arising from this heterogeneity. Extant literature on social control in OCCs is fragmented as some studies focus on the principles of social control, while others focus on the implementation. Moreover, the domain is undertheorized. This article integrates the disparate literature on social control in OCCs providing a first unified conceptualization of the topic. The authors conceptualize social control as a system, or configuration, of moderation practices. Moderation practices are executed during interactions operating under different governance structures (market, hierarchy, and clan) and serving different purposes (interaction initiation, maintenance, and termination). From this conceptualization, important areas of future research emerge and research questions are developed. The framework also serves as a community management tool for OCC managers, enabling the diagnosis of social control problems and the elaboration of strategies and tactics to address them

Virtuele communities voorbij de hype: Nieuw inzichten voor managers, marketeers en marktonderzoekers

Consumenten leggen steeds vaker contact met elkaar via het Internet. Elektronische discussieforums, mededelingenborden, nieuwsgroepen, e-maillijsten, chatrooms en weblogs bieden consumenten, waar dan ook ter wereld, de mogelijkheid om hun kennis, ervaringen en meningen te delen. De populariteit van deze elektronische contacten tussen consumenten blijkt uit de grote hoeveelheid virtuele communities die georganiseerd zijn rondom consumptiegerelateerde interesses. Dit soort communities vertegenwoordigen uitgebreide netwerken van consumptiekennis en kameraadschap die invloed hebben op consumentengedrag. In dit artikel gaan we in op een aantal nieuwe inzichten ten aanzien van virtuele communities die managers, marketeers en marktonderzoekers beter in staat stellen om strategisch gebruik te maken van de vele mogelijkheden die nu nog vaak onbenut worden gelaten

Why online consumption communities brutalize

Consumers who socialize in online consumption communities sometimes become alarmingly hostile, toxic, and otherwise verbally violent toward one another—a phenomenon known in sociology as brutalization. Research indicates that short-lived, situational outbursts of verbal violence—such as gross insults, harassment, or trolling—are common in online consumption contexts. However, it does not explain why such behaviors sometimes become endemic, turning entire communities into toxic social spaces. To address this question, the authors studied 18 years of interactions in an online electronic dance music community. Their interpretive analysis reveals three constellations of interacting, mutually reinforcing, forms of direct, structural, and cultural violence—sadistic entertainment, clan warfare, and popular justice—that fuel community brutalization in distinct ways. This article introduces these brutalization constellations, substantiates them with empirical data, and discusses their implications for theories of violence in consumption communities as well as the wider social media sphere

Social media use and impact during the holiday travel planning process

Through an empirical study among holiday travellers, residing in the Former Soviet Union Republics, this paper presents a comprehensive view of role and impact of social media on the whole holiday travel planning process: Before, during and after the trip, providing insights on usage levels, scope of use, level of influence and trust. Findings suggest that social media are predominantly used after holidays for experience sharing. It is also shown that there is a strong correlation between perceived level of influence from social media and changes made in holiday plans prior to final decisions. Moreover, it is revealed that user-generated content is perceived as more trustworthy when compared to official tourism websites, travel agents and mass media advertising

The Zinc Finger Protein A20 Inhibits TNF-induced NF-κB–dependent Gene Expression by Interfering with an RIP- or TRAF2-mediated Transactivation Signal and Directly Binds to a Novel NF-κB–inhibiting Protein ABIN

The zinc finger protein A20 is a tumor necrosis factor (TNF)– and interleukin 1 (IL-1)-inducible protein that negatively regulates nuclear factor-kappa B (NF-κB)–dependent gene expression. However, the molecular mechanism by which A20 exerts this effect is still unclear. We show that A20 does not inhibit TNF- induced nuclear translocation and DNA binding of NF-κB, although it completely prevents the TNF- induced activation of an NF-κB–dependent reporter gene, as well as TNF-induced IL-6 and granulocyte macrophage–colony stimulating factor gene expression. Moreover, NF-κB activation induced by overexpression of the TNF receptor–associated proteins TNF receptor–associated death domain protein (TRADD), receptor interacting protein (RIP), and TNF recep- tor–associated factor 2 (TRAF2) was also inhibited by expression of A20, whereas NF-κB activation induced by overexpression of NF-κB–inducing kinase (NIK) or the human T cell leukemia virus type 1 (HTLV-1) Tax was unaffected. These results demonstrate that A20 inhibits NF-κB–dependent gene expression by interfering with a novel TNF-induced and RIP- or TRAF2-mediated pathway that is different from the NIK–IκB kinase pathway and that is specifically involved in the transactivation of NF-κB. Via yeast two-hybrid screening, we found that A20 binds to a novel protein, ABIN, which mimics the NF-κB inhibiting effects of A20 upon overexpression, suggesting that the effect of A20 is mediated by its interaction with this NF-κB inhibiting protein, ABIN

A theoretical framework to describe communication processes during medical disability assessment interviews

BACKGROUND: Research in different fields of medicine suggests that communication is important in physician-patient encounters and influences satisfaction with these encounters. It is argued that this also applies to the non-curative tasks that physicians perform, such as sickness certification and medical disability assessments. However, there is no conceptualised theoretical framework that can be used to describe intentions with regard to communication behaviour, communication behaviour itself, and satisfaction with communication behaviour in a medical disability assessment context. OBJECTIVE: The objective of this paper is to describe the conceptualization of a model for the communication behaviour of physicians performing medical disability assessments in a social insurance context and of their claimants, in face-to-face encounters during medical disability assessment interviews and the preparation thereof. CONCEPTUALIzATION: The behavioural model, based on the Theory of Planned Behaviour (TPB), is conceptualised for the communication behaviour of social insurance physicians and claimants separately, but also combined during the assessment interview. Other important concepts in the model are the evaluation of communication behaviour (satisfaction), intentions, attitudes, skills, and barriers for communication. CONCLUSION: The conceptualization of the TPB-based behavioural model will help to provide insight into the communication behaviour of social insurance physicians and claimants during disability assessment interviews. After empirical testing of the relationships in the model, it can be used in other studies to obtain more insight into communication behaviour in non-curative medicine, and it could help social insurance physicians to adapt their communication behaviour to their task when performing disability assessment

NRP/Optineurin Cooperates with TAX1BP1 to Potentiate the Activation of NF-κB by Human T-Lymphotropic Virus Type 1 Tax Protein

Nuclear factor (NF)-κB is a major survival pathway engaged by the Human T-Lymphotropic Virus type 1 (HTLV-1) Tax protein. Tax1 activation of NF-κB occurs predominantly in the cytoplasm, where Tax1 binds NF-κB Essential Modulator (NEMO/IKKγ) and triggers the activation of IκB kinases. Several independent studies have shown that Tax1-mediated NF-κB activation is dependent on Tax1 ubiquitination. Here, we identify by co-immunoprecipitation assays NEMO-Related Protein (NRP/Optineurin) as a binding partner for Tax1 in HTLV-1 infected and Tax1/NRP co-expressing cells. Immunofluorescence studies reveal that Tax1, NRP and NEMO colocalize in Golgi-associated structures. The interaction between Tax1 and NRP requires the ubiquitin-binding activity of NRP and the ubiquitination sites of Tax1. In addition, we observe that NRP increases the ubiquitination of Tax1 along with Tax1-dependent NF-κB signaling. Surprisingly, we find that in addition to Tax1, NRP interacts cooperatively with the Tax1 binding protein TAX1BP1, and that NRP and TAX1BP1 cooperate to modulate Tax1 ubiquitination and NF-κB activation. Our data strongly suggest for the first time that NRP is a critical adaptor that regulates the assembly of TAX1BP1 and post-translationally modified forms of Tax1, leading to sustained NF-κB activation
