Announcing Pregnancy Loss on Facebook: A Decision-Making Framework for Stigmatized Disclosures on Identified Social Network Sites

論文アブストラクト: Pregnancy loss is a common experience that is often not disclosed in spite of potential disclosure benefits such as social support. To understand how and why people disclose pregnancy loss online, we interviewed 27 women in the U.S. who are social media users and had recently experienced pregnancy loss. We developed a decision-making framework explaining pregnancy loss disclosures on identified social network sites (SNS) such as Facebook. We introduce network-level reciprocal disclosure, a theory of how disclosure reciprocity, usually applied to understand dyadic exchanges, can operate at the level of a social network to inform decision-making about stigmatized disclosures in identified SNSs. We find that 1) anonymous disclosures on other sites help facilitate disclosure on identified sites (e.g., Facebook), and 2) awareness campaigns enable sharing about pregnancy loss for many who would not disclose otherwise. Finally, we discuss conceptual and design implications. CAUTION: This paper includes quotes about pregnancy loss.

Falling for Fake News: Investigating the Consumption of News via Social Media

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173950

論文アブストラクト: In the so called 'post-truth' era, characterized by a loss of public trust in various institutions, and the rise of 'fake news' disseminated via the internet and social media, individuals may face uncertainty about the veracity of information available, whether it be satire or malicious hoax. We investigate attitudes to news delivered by social media, and subsequent verification strategies applied, or not applied, by individuals. A survey reveals that two thirds of respondents regularly consumed news via Facebook, and that one third had at some point come across fake news that they initially believed to be true. An analysis task involving news presented via Facebook reveals a diverse range of judgement forming strategies, with participants relying on personal judgements as to plausibility and scepticism around sources and journalistic style. This reflects a shift away from traditional methods of accessing the news, and highlights the difficulties in combating the spread of fake news.

The Context of College Students' Facebook Use and Academic Performance: An Empirical Study

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173992

論文アブストラクト: The effects of Facebook on academic performance have attracted both public and scholarly attention. Prior research found that Facebook use is linked to poor academic performance, suggesting that Facebook distracts students from studying. These studies, which are primarily based on survey responses, are insufficient to uncover exactly how Facebook is used or embedded in students' studying activities. To capture unbiased, detailed use patterns and to investigate the context of Facebook use, we studied 50 college students using automatic logging and experience sampling. We analyzed the activities and attentional states of students prior to visiting Facebook. Results show that GPAs of frequent Facebook users do not suffer. Students with high GPAs spend shorter time in each Facebook session and shorter Facebook use often follows schoolwork. These results point to a possibility that potentially problematic Facebook use occurs when students are in a spree of leisure activities, not while studying.

Personality Depends on The Medium: Differences in Self-Perception on Snapchat, Facebook and Offline

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174181

論文アブストラクト: We investigate self-perception in social media through the lens of personality theory. Two mixed-methods studies involving 148 participants examine if people self-report different personality traits in social media compared with their offline traits. We first compare offline and Facebook traits, finding that on Facebook people are less Neurotic, Open and Agreeable. A second study compared offline, Facebook and Snapchat traits, replicating and extending our initial results. Again Facebook personality was less Neurotic and less Open than offline. In contrast, Snapchat personality was more Extravert than both offline and Facebook and more Open than Facebook. Interviews indicate how personality differences arise from social media affordances. Anxiety about audience judgments leads people to curate posts to appear less Neurotic on social media, but the transience of Snapchat promotes greater Extraversion than offline and Facebook. We discuss theory and design implications.
