What is a social medium, and how may one moderate, isolate, influence communicative processes within? Although scholars assume an inherent understanding of media based on extant technology, there no commonly accepted definition what are, both functionally theoretically, within communication studies. Given this lack understanding, cogent theorizing regarding the uses effects has been limited. This work first draws definitions subcategories (e.g., network sites) from public relations,...
In this study we conceptualize cues in social media that require a single click (e.g., Likes, Favorites) as paralinguistic digital affordances (PDAs). Why do people use PDAs and how they interpret them when are the recipient? Through focus groups (N = 25) interviews 26) address these research questions within uses gratifications framework. Using adaptive structuration theory lens for analysis, examine both faithful ironic of PDAs, finding contribute more than phatic communication may...
AbstractUtilizing the two-step flow model, study sought to understand effects of perceived third-party influence in social media. Blogger relations is a common strategy public relations, and frequently results compensation for coverage. Disclosure these relationships can vary explicitness, though impact disclosure unknown. A national sample (N = 405) participated an experiment which blog product review varied its acknowledged influence. Results indicate explicitness links between message...
A national survey asked 323 U.S. adults about paralinguistic digital affordances (PDAs) and how these forms of lightweight feedback within social media were associated with their perceived support. People PDAs (e.g., Likes, Favorites, Upvotes) as socially supportive both quantitatively qualitatively, even without implicit meaning them. who are highly sensitive what others think them have high self-esteem more likely to perceive higher support from PDAs.
Abstract Machine learning approaches using structural magnetic resonance imaging (sMRI) can be informative for disease classification, although their ability to predict psychosis is largely unknown. We created a model with individuals at CHR who developed later (CHR-PS+) from healthy controls (HCs) that differentiate each other. also evaluated whether we could distinguish CHR-PS+ those did not develop (CHR-PS-) and uncertain follow-up status (CHR-UNK). T1-weighted brain MRI scans 1165...
Public relations practitioners are actively building relationships with bloggers to obtain high-credibility brand mentions and reviews. Practitioners may request limit comments maintain control over messages constrain dissonant perspectives; however, the impact of limiting social features blogs is unknown. Utilizing source credibility warranting theory, this article examines relationship between enabled on attitudes, moderating variables expertise, from both a public consumer behavior...
Portable low-field-strength magnetic resonance imaging (MRI) systems represent a promising alternative to traditional high-field-strength with the potential make MR technology available at scale in low-resource settings. However, lower image quality and resolution may limit research clinical of these devices. We tested two super-resolution methods enhance low-field system compared their correspondence images acquired from high-field sample young people.
Responding to recent calls transcend social media platforms when examining effects, and using the information processing model predict explain results, this multi-method study first uses a US national survey ( N = 325) examine perceived effectiveness of support relational closeness via paralinguistic digital affordances (PDAs; e.g., “Likes,” “+1s,” “Upvotes”)—the one-click tools for phatic communication—between platforms. Results reveal some significant between-platform differences in...
Abstract Study Objectives Structural brain maturation and sleep are complex processes that exhibit significant changes over adolescence linked to many physical mental health outcomes. We investigated whether sleep–gray matter relationships developmentally invariant (i.e. stable across age) or specific only present during discrete time windows) from late childhood through young adulthood. Methods constructed the Neuroimaging Pediatric Sleep Databank eight research studies conducted at...
Individuals at Clinical High Risk for Psychosis (CHR-P) demonstrate heterogeneity in clinical profiles and outcome features. However, the extent of neuroanatomical CHR-P state is largely undetermined. We aimed to quantify structural magnetic resonance imaging measures cortical surface area (SA), thickness (CT), subcortical volume (SV), intracranial (ICV) individuals compared with healthy controls (HC), relation subsequent transition a first episode psychosis. The ENIGMA consortium applied...
This research explores the processes of perceived ostracism ensuing from a lack feedback via paralinguistic digital affordances (PDAs), one-click tools (e.g., Likes and +1s) which are one most used features social media, provided to an individual’s posted media content. The positive negative psychological outcomes communication have been well-documented. However, as become entrenched some our common channels, absence has underexplored may communicative outcomes. We utilized focus groups ( N...
Abstract Probing naturally-occurring, reciprocal genomic copy number variations (CNVs) may help us understand mechanisms that underlie deviations from typical brain development. Cross-sectional studies have identified prominent reductions in cortical surface area (SA) and increased thickness (CT) 22q11.2 deletion carriers (22qDel), with the opposite pattern duplication (22qDup), but longitudinal trajectories of these anomalies—and their relationship to clinical symptomatology—are unknown....
Individuals frequently engage in self-presentation via social media and can subsequently receive various simple communicative cues (paralinguistic digital affordances; PDAs) from which they may determine the success of their self-presentation, including Likes Upvotes. Previous research has found these communicatively abstract one-click are interpreted idiosyncratically when received, but quantity received matters to users determining whether a post is "successful." The present work probes...
Extending prior research that has noted individuals' self-presentation and subsequent feedback can affect self-perceptions, we report 2 studies assessing this identity shift with respect to brand the effect of (dis)confiratory feedback. Synthesizing literature from media consumer psychology, hypotheses are derived predicting both main interaction effects congruence presentation on self-perceptions. Two experiments had participants selectively self-present themselves as either a loyal...
This study explores Facebook users' management behaviors related to their—and their friends'—political communication via social media, utilizing the concepts of context collapse and self-presentation. A new two-factor measure was developed, pilot tested (N = 139) implemented in a survey national sample 352) individuals aged 18–29. Results indicated users are not generally engaging strategic political disclosures or content which they exposed. However, as network sizes increase, participants...
The microbiome of flowers (anthosphere) is an understudied compartment the plant microbiome. Within flower, petals represent a heterogeneous environment for microbes in terms resources and environmental stress. Yet, little known drivers structure function epiphytic microbial community at within-petal scale. We characterized petal two co-flowering plants that differ pattern ultraviolet (UV) absorption along their petals. Bacterial communities were similar between hosts, with only rare...
Objectives: Adolescence is marked by significant changes in sleep physiology, which provides crucial insights into brain development and health outcomes. However, has been difficult to measure on a large scale due the limitations of polysomnography. Emerging portable devices, like Dreem3 headband (Dreem3), offer scalable accessible alternative, with validation studies adults showing strong feasibility accuracy, but data for adolescents remain limited. This pilot study evaluated acceptability...
Abstract Harvested forests have the potential to support pollinator conservation, particularly when enhanced with native flowers, yet their conservation value remains largely untapped and undetermined. Because bee diversity abundance are closely linked of our study examined effectiveness floral enhancements seeded in wildfire-affected harvested Oregon’s Cascade Mountains, US. We assessed richness, abundance, cover, availability, persistence 20 plant species sown two contexts: burned slash...
