Patterns of Chatter: An Empirical Case Study of Participation in an Online Health Community

This research-in-progress is an in-depth case study of the patterns of interactions between participants in a virtual community. The study will examine the stability of the community membership, posting behavior of the members over time, the existence of clusters or groups of users, especially a core group, and the possible classification of members based upon participation. Social network analysis diagrams showing who is talking to whom will be produced, revealing the social structure of the community. All 16,112 messages posted by 1,670 users of a medical virtual community were gathered over the course of one year. Preliminary results are given and future analysis of the data is proposed

Applying TAM to a Paralell Systems Conversion Strategy

According to the Technology Acceptance Model (TAM) user perceptions of usefulness and ease of use are major determinants of IT adoption. Extensive research dealing with direct cut over implementation of new IT in field settings support this assertion. In today’s market, however, new IT are often deployed using a parallel systems strategy: new IT are implemented while existing IT are retained so that both IT work in parallel for some time. This study suggests and supports a model showing that user preference for using the new IT depends on user assessment of the usefulness of both the old IT and the new IT. Survey data from a large telecommunications organization that was in the process of adopting a new customer service system while continuing to run the older system in parallel, shows that the respondents?overall preference to use the new IT was, as hypothesized, affected by user perceptions of both IT: perceived usefulness of the new IT increased user preference to adopt the new IT, while perceived usefulness of the old IT decreased it. The perceived usefulness of each system was, as suggested by TAM, increased by the perception of its ease of use. Implications are discussed

Online discussion group sustainability: Investigating the interplay between structural dynamics and social dynamics over time

Online discussion groups have become an increasingly popular way to create social networks where individuals congregate electronically to share advice and ideas. In order to better understand sustainability, we propose that research needs to go beyond examining quantitative changes in the structural dynamics of online discussion groups (such as membership size and message volume) and include investigation of the social dynamics characterizing the underlying qualities of the interactions among members. We take a mixed-methods approach to provide qualitative and empirical support for our theory by investigating the dynamics of one successful online discussion group over a five-year period. Our data set includes all 150,267 messages posted to 27,743 threads by 9,042 unique individuals over a five year period in a group that is focused on sharing advice about a medical topic (back pain). We find support for our hypotheses that 1) shifts in the structural and social dynamics underlying resource availability lead to changes in communication activities, but in unexpected ways: Fewer members contributed significantly more message volume. In turn, 2) shifts in the structural and social dynamics underlying communication activities lead to changes in coping strategies: As message volume increased and became more social, members increased their efforts and were less likely to defect. Finally, 3) shifts in the structural and social dynamics underlying coping strategies lead to changes in attraction and retention: as individual efforts increased, more individuals were retained; however, fewer new members were attracted to join the group. Our main thesis is that each online discussion group is a product of its structural and social dynamics in combination, and the influence of these factors on sustainability is best understood when they are examined in relation to each other over time

Psychological Barriers: Lurker and Poster Motivation and Behavior in Online Communities

Virtual communities provide an attractive place for organizations to mine information regarding customer perceptions, needs, and demographics; as well as to generate revenue through sales of products, services, information, and advertising. However, the community conversation provides information about only one type of community user, the poster. Information about the lurker, who never posts, is conspicuously absent from the obvious community data source, the postings. Lurkers may be a large portion of the user community and could provide key revenue sources and vital information, or they potentially could turn into posters. This research contrasts the differences in the underlying motivations of lurkers, infrequent posters, and posters in order to understand the resulting differences in their behavior. 518 users from 20 virtual communities were categorized into three groups based upon their posting behaviors: lurkers who never posted, infrequent posters who posted three or less times per month, and frequent posters. Results revealed that lurkers differed significantly from posters, especially in their willingness to give information and exchange social support. There was a gradual progression from lurker to poster regarding the desires to get knowledge and obtain shopping information. Implications about a possible psychological barrier regarding giving information and social support are discussed

Emotional Dysregulation and Borderline Personality Disorder: Explaining the Link between Secondary Psychopathy and Alexithymia

Research explaining the overlap between psychopathy and alexithymia is in its infancy. A study by Lander, Lutz-Zois, Rye, and Goodnight (2012) revealed a significant positive correlation between secondary, but not primary, psychopathy and alexithymia. However, little is known about what accounts for this differential association. Because both alexithymia (Webb & McMurran, 2008) and secondary psychopathy (Blackburn, 1996) have been linked to Borderline Personality Disorder (BPD), the current study sought to determine if emotional processing deficits characteristic of BPD could explain the link between secondary psychopathy and alexithymia. The results supported the hypothesis that BPD would mediate the association between secondary psychopathy and alexithymia. Implications, limitations, and future directions are discussed

Growing Local Food Systems: Information Technology Use and Impacts in Geographically-Embedded Markets

Over recent decades, reliance on global food systems involving highly distributed supply chains has increased. However, as awareness of environmental, social, and health consequences of these arrangements has developed, so has interest in local food systems (LFSs) in which consumers are served by nearby producers and intermediaries. Yet, in spite of the purported benefits of LFSs, there are challenges which limit their impact. There is an opportunity for IS scholars to contribute by examining how technology is and could be used in geographically-embedded markets like LFSs. We draw on prior studies of IT use and impacts in markets to generate exploratory propositions regarding ways that IT might be used to in LFSs. The results have the potential to build a bridge between IS research and the study and development of LFSs and, thus, create opportunities for IS scholars to contribute directly to the economic health and quality of life of communities

An Examination of Gender Differences in the Construct Validity of the Silencing the Self Scale

Jack’s (1991) theory of self-silencing was originally designed to explain higher rates of depression in women in comparison to men. However, research finding that men score equal or even higher than women on measures of self-silencing has led theorists to speculate that self-silencing tendencies may be driven by different motivations and have different consequences for women versus men (Jack & Ali, 2010). Using a sample of 247 college students, we examined gender differences in the construct validity of the Silencing the Self Scale (STSS; Jack & Dill, 1992). We hypothesized that women would score higher on the Externalized Self-Perception subscale, but not in the other three subscales. Gender differences in the relationship between the STSS subscales and theoretically relevant constructs were also explored. The results indicated that women on average scored higher than men on the Externalized Self-Perception subscale, whereas men scored higher on the Care as Self-Sacrifice subscale. Further, there was a significant Gender × Care as Self-Sacrifice subscale interaction in the prediction of depression, such that this subscale was negatively correlated to depression in men and uncorrelated in women. These results clarify how self-silencing might translate into different mental health outcomes for women and men. Highlights: As hypothesized, women scored higher on the Externalized Self-Perception subscale of the STSS. * We examined Gender × Subscale interactions in prediction of theoretically-relevant constructs. * The Gender × Care as Self-Sacrifice subscale interaction significantly predicted depression
