TL;DR: Young adult cancer survivors with weak ''bonding'' social capital with other cancer survivors, little social support from friends and family, and lower family interaction participated in the social networking intervention more than those with stronger social capital and larger bases of support.

TL;DR: The findings revealed that PrEP-related information on Twitter covered a wide range of issues, and individual users constituted the majority of the Tweet creators among all the sources, including news media, nonprofit and academic groups, and commercial entities.
Abstract: Previous literature has suggested that examining Twitter messages can be productive for studying how the public shares and spreads health information on social media. Preexposure prophylaxis (PrEP) is a promising approach to HIV prevention, yet there are many issues that may influence its effective implementation. This study examined social representations of PrEP on Twitter. One thousand four hundred and thirty-five Tweets were collected and 774 English Tweets were content-analyzed to explore propagation of various issues around daily oral PrEP, as well as characteristics of the sources of those Tweets. We also examined how Twitter message content influenced information propagation. Our findings revealed that PrEP-related information on Twitter covered a wide range of issues, and individual users constituted the majority of the Tweet creators among all the sources, including news media, nonprofit and academic groups, and commercial entities. Using Poisson regression, we also found that a Tweet's affective tone was a significant predictor of message propagation frequency. Implications for health practitioners are discussed.

TL;DR: Although pediatric cancer survivors often do not publicly discuss a “cancer survivor identity,” they do internalize both positive and negative stereotypes about cancer survivorship, and it is important for practitioners to be aware of the long-term implications of cancer survivor identity and stereotypes.

TL;DR: It was found that Twitter was used to generate public discussions and collectively interpret new medical information, especially in frequently propagated tweets and from users with more followers, which revealed the presence of illicit online pharmacies that marketed and sold PrEP without the need for a prescription.
Abstract: Daily oral pre-exposure prophylaxis PrEP is a new approach to HIV prevention. The study aims to examine how PrEP has been represented and disseminated on one of the most popular social networking sites - Twitter. We collected 1435 public tweets containing the word "Truvada." After computer-mediated and manual de-duplication, we analyzed 447 unique tweets and calculated weights between two words to measure their co-occurrence in 7-word windows. Semantic networks of PrEP-related tweets were constructed. We found that Twitter was used to generate public discussions and collectively interpret new medical information, especially in frequently propagated tweets and from users with more followers. In the meantime, the results revealed the presence of illicit online pharmacies that marketed and sold PrEP without the need for a prescription. We discussed implications for public health and made urgent call for better regulation of online pharmacies.

TL;DR: The current meta-analysis synthesizes decades of empirical research examining the effect of immersive system technology on user experiences of presence and finds that technological immersion has a medium-sized effect on presence.
Abstract: The concept of presence, or “being there” is a frequently emphasized factor in immersive mediated environments. It is often assumed that greater levels of immersive quality elicit higher levels of presence, in turn enhancing the effectiveness of a mediated experience. To investigate this assumption the current meta-analysis synthesizes decades of empirical research examining the effect of immersive system technology on user experiences of presence. Aggregating 115 effect sizes from 83 studies, it finds that technological immersion has a medium-sized effect on presence. Additionally, results show that increased levels of user-tracking, the use of stereoscopic visuals, and wider fields of view of visual displays are significantly more impactful than improvements to most other immersive system features, including quality of visual and auditory content. These findings are discussed in light of theoretical accounts of the presence construct as well as practical implications for design.

TL;DR: Evidence suggests that SNSs differentially relate to adolescents’ social connectivity and identity development, with sociability, self-esteem, and nature of SNS feedback as important potential moderators.
Abstract: Since the advent of social networking site (SNS) technologies, adolescents' use of these technologies has expanded and is now a primary way of communicating with and acquiring information about others in their social network. Overall, adolescents and young adults' stated motivations for using SNSs are quite similar to more traditional forms of communication-to stay in touch with friends, make plans, get to know people better, and present oneself to others. We begin with a summary of theories that describe the role of SNSs in adolescents' interpersonal relationships, as well as common methodologies used in this field of research thus far. Then, with the social changes that occur throughout adolescence as a backdrop, we address the ways in which SNSs intersect with key tasks of adolescent psychosocial development, specifically peer affiliation and friendship quality, as well as identity development. Evidence suggests that SNSs differentially relate to adolescents' social connectivity and identity development, with sociability, self-esteem, and nature of SNS feedback as important potential moderators. We synthesize current findings, highlight unanswered questions, and recommend both methodological and theoretical directions for future research.
