Micro-blogging systems have become one of the most important ways for information sharing. Network structure and users' interactions such as forwarding behaviors have aroused considerable research attention, while mention, as a key feature in micro-blogging platforms which can improve the visibility of a message and direct it to a particular user beyond the underlying social structure, is seldom studied in previous works. In this paper, we empirically study the mention effect in information diffusion, using the dataset from a population-scale social media website...

Introduction Podcasts and blog posts have gained popularity in Free Open Access Medical education (FOAM). Previous work suggests that podcasts may be useful for knowledge acquisition in undergraduate medical education. However, there remains a paucity of research comparing the two mediums. This study aims to investigate if there are differences in knowledge acquisition and usage conditions by medical students using podcasts and blog posts. Methods Medical students were randomized to either the podcast or blog post group...

The advent of Web 2.0 is changing tourists' behaviors, prompting them to take on a more active role in preparing their travel plans. It is also leading tourism companies to have to adapt their marketing strategies to different online social media. The present study analyzes advertising effectiveness in social media in terms of customers' visual attention and self-reported memory (recall). Data were collected through a within-subjects and between-groups design based on eye-tracking technology, followed by a self-administered questionnaire...

BACKGROUND: Air quality affects us all and is a rapidly growing concern in the 21st century. We spend the majority of our lives indoors and can be exposed to a number of pollutants smaller than 2.5 microns (particulate matter, PM2.5 ) resulting in detrimental health effects. Indoor air quality sensors have the potential to provide people with the information they need to understand their risk and take steps to reduce their exposure. One such sensor is the Speck sensor developed at the Community Robotics, Education and Technology Empowerment Lab at Carnegie Mellon University...

INTRODUCTION: The number of websites for the critical care provider is rapidly growing, including websites that are part of the Free Open Access Med(ical ed)ucation (FOAM) movement. With this rapidly expanding number of websites, critical appraisal is needed to identify quality websites. The last major review of critical care websites was published in 2011, and thus a new review of the websites relevant to the critical care clinician is necessary. METHODS: A new assessment tool for evaluating critical care medicine education websites, the Critical Care Medical Education Website Quality Evaluation Tool (CCMEWQET), was modified from existing tools...

We aimed to determine the types of identities hearing parents construct when telling online stories about their children with hearing loss (HL) who use cochlear implants (CIs). To do so, we employed a qualitative design and sampled 20 different blogs United States origins and written by parents of children who use CIs. We then used thematic narrative analysis (Braun & Clarke, 2006; Riessman, C. K. (2008). Narrative methods for the human sciences. Thousand Oaks, CA: Sage Publications.) to uncover recurring themes from these parents' blogs...

OBJECTIVE: Popular media applications have been shown to benefit people with severe mental illness by facilitating communication and social support, helping patients cope with or manage symptoms, and providing a way to monitor or predict mental health states. Although many studies of technology use by individuals with severe mental illness have focused primarily on use of social media, this study provides additional information about use of Internet applications such as blogs, wikis (websites that allow collaborative editing of content and structure by users), video games, and Skype by a community psychiatry population...

BACKGROUND: Online educational resources are criticized as being teacher-centred, failing to address learner's needs. Needs assessments are an important precursor to inform curriculum development, but these are often overlooked or skipped by developers of online educational resources due to cumbersome measurement tools. Novel methods are required to identify perceived and unperceived learning needs to allow targeted development of learner-centred curricula. OBJECTIVES: To evaluate the feasibility of performing a novel technique dubbed the Massive Online Needs Assessment (MONA) for the purpose of emergency haematology online educational curricular planning, within an online learning community (affiliated with the Free Open Access Medical education movement)...

BACKGROUND: Supporting Our Valued Adolescents (SOVA), a social media website for adolescents, was designed to increase mental health literacy and address negative health beliefs toward depression and/or anxiety diagnosis and treatment. This stakeholder-informed site underwent iterative user testing to evolve into its current version with daily blog posts, round-the-clock site moderation, and Web-based peer interaction to create an online support community. OBJECTIVE: The aim of this study was to evaluate the technological feasibility (at least 100 users on the site, logging in 12 to 18 times in the first 6 weeks) and acceptability of the SOVA site determined by the System Usability Scale (SUS)...

Background : Physician well-being is garnering increasing attention. In 2016, the Journal of Graduate Medical Education ( JGME ) published a review by Kristin Raj, MD, entitled "Well-Being in Residency: A Systematic Review." There is benefit in contextualizing the literature on resident well-being through an academic journal club. Objective : We summarized an asynchronous, online journal club discussion about this systematic review and highlighted themes that were identified in the review...

BACKGROUND: Social media platforms are increasingly used by registered dietitians (RDs) to improve knowledge translation and exchange in nutrition. However, a thorough understanding of social media in dietetic practice is lacking. OBJECTIVE: The objective of this study was to map and summarize the evidence about the users, uses, and effects of social media in dietetic practice to identify gaps in the literature and inform future research by using a scoping review methodology...

Purpose: We sought to determine whether big data from social media might reveal seasonal trends of conjunctivitis, most forms of which are nonreportable. Methods: Social media posts (from Twitter, and from online forums and blogs) were classified by age and by conjunctivitis type (allergic or infectious) using Boolean and machine learning methods. Based on spline smoothing, we estimated the circular mean occurrence time (a measure of central tendency for occurrence) and the circular variance (a measure of uniformity of occurrence throughout the year, providing an index of seasonality)...

INTRODUCTION: There is increasing interest in social digital media (SDM) as a data source for pharmacovigilance activities; however, SDM is considered a low information content data source for safety data. Given that pharmacovigilance itself operates in a high-noise, lower-validity environment without objective 'gold standards' beyond process definitions, the introduction of large volumes of SDM into the pharmacovigilance workflow has the potential to exacerbate issues with limited manual resources to perform adverse event identification and processing...

BACKGROUND: The future of health care services in the European Union faces the triple challenges of aging, fiscal restriction, and inclusion. Co-production offers ways to manage informal care resources to help them cater for the growing needs of elderly people. Social media (SM) is seen as a critical enabler for co-production. OBJECTIVE: The objective of this study was to investigate how SM-private Facebook groups, forums, Twitter, and blogging-acts as an enabler of co-production in health and care by facilitating its four underlying principles: equality, diversity, accessibility, and reciprocity...
