    Description: Social cognitive theory is often implemented when researchers develop treatments and campaigns for health behavior change. Immersive virtual environment technology (IVET) enables novel explorations of health behavior modeling. In Study 1, participants were randomly assigned to one of three treatments: vicarious reinforcement, in which a virtual representation of the physical self (VRS) gained or lost weight in accordance with participants' physical exercise; an unchanging VRS; or no virtual representation. The reinforcement group performed significantly more exercise in a voluntary phase than those in other conditions. Study 2 separated reward (weight loss) from punishment (weight gain) and also explored model identification by contrasting the effects of a VRS with a VRO (virtual representation of an other); participants exercised significantly more when they viewed the VRS, regardless of whether reward or punishment was shown. In Study 3, participants were exposed to either a VRS running on a treadmill, a VRO running, or a VRS loitering, and we examined effects 24 hours after the experiment. Follow-up surveys revealed that participants in the VRS-running condition demonstrated significantly higher levels of exercise than those in other conditions. We discuss implications for media use and health communication.

    Description: Although previous research has investigated relationships between media consumption, sexism, and rape myth acceptance (RMA), limited research has investigated video games despite their emergence as one of the most popular forms of media entertainment globally. Given that video games typically feature even less diverse and more objectified representations of women than traditional mainstream media, we predicted that there would be relationships between video game consumption and negative beliefs and attitudes about women. In this study, we conducted a survey (N = 351) of male and female adults and used structural equation modeling to analyze relationships among video game consumption, trait interpersonal aggression, ambivalent sexism, and first-order (percentage of false rape accusations) and second-order cultivation effects (RMA). We found support for the hypothesized cultivation model, indicating a relationship between video game consumption and RMA via interpersonal aggression and hostile sexism. Although these findings cannot be interpreted causally, we discuss the implications of these associations and future directions for research.

    Description: The concept of affordances in communication technology research has proven to be heuristically provocative, yet perceived affordances are rarely measured. After extracting commonly cited social affordances from the literature, we developed a measure to assess participants' perceptions of these affordances. The scale was tested across eight communication channels in two studies (face-to-face; texting; phone; email; posts on social networking sites, specifically Facebook; instant messaging; Skype videoconferencing; and mobile app Snapchat). A factor structure was developed in Study 1 and confirmed in Study 2. The resultant Perceived Social Affordances of Communication Channels Scale includes 41 items measuring 10 communicative affordances: accessibility, bandwidth, social presence, privacy, network association, personalization, persistence, editability, conversation control, and anonymity. Potential methodological and theoretical applications are discussed.

    Description: Social networking sites can facilitate self‐expression, but for some, that freedom is constrained. This study investigated factors that influence LGBT+ individuals' identity management and political expression on social media. We interviewed 52 participants aged 18 to 53 around the 2012 U.S. election. Using co‐cultural theory, we investigated communicative practices employed by queer‐identified individuals on Facebook. Participants whose LGBT+ identity was not known by the social network (i.e., those who were still in the closet) revealed a spiral of silence, wherein they were silenced by the perceived heteronormative majority. Participants whose identity was known (i.e., those who were out) revealed a spiral of silencing as they used the site's affordances to empower their vocal minority and silence the dominant group.

    Description: Online video games afford co‐play and social interaction, often anonymous, among players from around the world. As predicted by the social identity model of deindividuation effects, undesirable behavior is not uncommon in online gaming environments, and online harassment has become a pervasive issue in the gaming community. In this study, we sought to determine what personality traits and game‐related variables predicted two types of online aggression in video games: general harassment (e.g., skill‐based taunting, insulting others’ intelligence) and sexual harassment (e.g., sexist comments, rape threats). Men who play online video games (N = 425) participated in an anonymous online survey. Social dominance orientation and hostile sexism predicted higher levels of both sexual harassment and general harassment in online games. Game involvement and hours of weekly gameplay were additional predictors of general harassment. We discuss implications of online social aggression and online sexual harassment for online gaming. We also apply our findings to the broader understanding of online harassment, cyberaggression, cyberbullying, and other forms of online hostility in computer‐mediated communication contexts. Aggr.

    Description: This study examines the implications of social networking web sites (SNSs) within romantic relationships. Specifically, Knapp’s (1978) stage model of relationships is examined through a new lens wherein the role of SNSs, specifically Facebook, is explored in the escalation stages of romantic relationships (i.e., initiating, experimenting, intensifying, integrating, and bonding). Furthermore, this study sought to discern the interpersonal and social implications of publicly declaring oneself as “In a Relationship” with another person on Facebook (i.e., going “Facebook official” or “FBO”). Ten mixed-sex focus groups were conducted. Analysis revealed that Facebook is one of the primary means of uncertainty reduction in the initial stages of relationship formation. College students consider FBO to be indicative of an increased level of commitment in relationships. Typically, relationship exclusivity precedes a discussion on becoming FBO, which occurs when the relationship is considered stable. Going FBO has implications for the public proclamation of one’s relationship status as described in Knapp’s model, and these results differ for men and women. Theoretical implications for the role of SNSs in romantic relationships are discussed.

    Description: Many people fail to save what they will need for retirement. Research on excessive discounting of the future suggests that removing the lure of immediate rewards by precommitting to decisions or elaborating the value of future rewards both can make decisions more future oriented. The authors explore a third and complementary route, one that deals not with present and future rewards but with present and future selves. In line with research that shows that people may fail, because of a lack of belief or imagination, to identify with their future selves, the authors propose that allowing people to interact with age-progressed renderings of themselves will cause them to allocate more resources to the future. In four studies, participants interacted with realistic computer renderings of their future selves using immersive virtual reality hardware and interactive decision aids. In all cases, those who interacted with their virtual future selves exhibited an increased tendency to accept later monetary rewards over immediate ones.

    Description: Inflammation and macrophage foam cells are characteristic features of atherosclerotic lesions, but the mechanisms linking cholesterol accumulation to inflammation and LXR-dependent response pathways are poorly understood. To investigate this relationship, we utilized lipidomic and transcriptomic methods to evaluate the effect of diet and LDL receptor genotype on macrophage foam cell formation within the peritoneal cavities of mice. Foam cell formation was associated with significant changes in hundreds of lipid species and unexpected suppression, rather than activation, of inflammatory gene expression. We provide evidence that regulated accumulation of desmosterol underlies many of the homeostatic responses, including activation of LXR target genes, inhibition of SREBP target genes, selective reprogramming of fatty acid metabolism, and suppression of inflammatory-response genes, observed in macrophage foam cells. These observations suggest that macrophage activation in atherosclerotic lesions results from extrinsic, proinflammatory signals generated within the artery wall that suppress homeostatic and anti-inflammatory functions of desmosterol. [Display omitted] ► Desmosterol is the dominant LXR ligand formed in macrophage foam cells ► Desmosterol integrates cholesterol and fatty acid homeostasis in the macrophage ► Desmosterol inhibits activation of inflammatory responses in macrophages ► Macrophage activation in atherosclerosis is likely due to extrinsic mediators Cholesterol accumulation in peritoneal macrophages results in unexpected suppression, rather than activation, of inflammatory gene expression, suggesting that this response is suppressed in atherosclerotic lesions by extrinsic proinflammatory signals.

    Description: In eukaryotes three of the four ribosomal RNA (rRNA) molecules are transcribed as a long precursor that is processed into mature rRNAs concurrently with the assembly of ribosomal subunits. However, the relative timing of association of ribosomal proteins with the ribosomal precursor particles and the cleavage of the precursor rRNA into the subunit-specific moieties is not known. To address this question, we searched for ribosomal precursors containing components from both subunits. Particles containing specific ribosomal proteins were targeted by inducing synthesis of epitope-tagged ribosomal proteins followed by pull-down with antibodies targeting the tagged protein. By identifying other ribosomal proteins and internal rRNA transcribed spacers (ITS1 and ITS2) in the immuno-purified ribosomal particles, we showed that eS7/S7 and uL4/L4 bind to nascent ribosomes prior to the separation of 40S and 60S specific segments, while uS4/S9, uL22, and eL13/L13 are bound after, or simultaneously with, the separation. Thus, the incorporation of ribosomal proteins from the two subunits begins as a co-assembly with a single rRNA molecule, but is finished as an assembly onto separate precursors for the two subunits.

    Description: Research has indicated that many video games and virtual worlds are populated by unrealistic, hypersexualized representations of women, but the effects of using these representations remain understudied. Objectification theory suggests that women’s exposure to sexualized media representations leads to self-objectification. Further, we anticipated this process would lead to increases in rape myth acceptance (RMA). Two experiments (Study 1, N = 87; Study 2, N = 81) examined the effects of avatar features on women’s experiences of self-objectification. In both studies, college women exposed to sexualized avatars experienced higher levels of self-objectification after the virtual experience than those exposed to nonsexualized avatars. Furthermore, in Study 2, self-objectification mediated the relationship between controlling a sexualized avatar and subsequent levels of RMA. We discuss the implications of women using sexualized avatars in video games and virtual environments, which may lead to negative attitudes about the self and other women off-line due to heightened self-objectification.
