This paper presents a bibliographic analysis of Nature articles based on altmetrics. We assess the concern degree of social users on the Nature articles through the coverage analysis of Twitter and Facebook by publication year and discipline. The social media impact of a Nature article is examined by evaluating the mention rates on Twitter and on Facebook. Moreover, the correlation between tweets and citations is analyzed by publication year, discipline and Twitter user type to explore factors affecting the correlation. The results show that Twitter users have a higher concern degree on Nature articles than Facebook users, and Nature articles have higher and faster-growing impact on Twitter than on Facebook. The results also show that tweets and citations are somewhat related, and they mostly measure different types of impact. In addition, the correlation between tweets and citations highly depends on publication year, discipline and Twitter user type. PMID:27906981

Facebook and Twitter have change interpersonal relationships. Adolescents are the sector of the population who use most these networks. They use them in an emotional way, to express their emotions and to comment on those of others. Empathy, narcissism, and self-esteem may play an important role in the use of these networks. Using a sample of 503 Spanish adolescents (272 males, 231 females), this work studies the relationship between the Basic Empathy Scale, the Narcissistic Personality Inventory, the Rosenberg Self-Esteem Scale, and emotional and empathic use of Facebook and Twitter. The results showed that those who use Facebook and Twitter have higher scores in empathy. It has been observed that certain ways of using these two social networks are associated with narcissism. Greater use of Facebook and Twitter is associated with lower self-esteem.

Purpose Current trends suggest adolescents and young adults typically maintain a social media “portfolio” of several sites including Facebook and Twitter, but little is known regarding how an individual chooses to display risk behaviors across these different sites. The purpose of this study was to investigate college students’ displayed alcohol references on both Facebook and Twitter. Methods Among a larger sample of college students from two universities, we identified participants who maintained both Facebook and Twitter profiles. Data collection included evaluation of 5 months of participants’ Facebook and Twitter posts for alcohol references, number of social connections (i.e. friends or followers) and number of posts. Phone interviews assessed participants’ frequency of Facebook and Twitter use and self-reported alcohol use. Analyses included Fisher’s exact test, Wilcoxon matched pair sign test, Freidman rank-sum tests and logistic regression. Results Of 112 eligible participants, 94 (RR=84.8%) completed the study. Participants were more likely to display alcohol references on Facebook compared to Twitter (76% versus 34%, p=0.02). Participants reported more social connections on Facebook versus Twitter (average 801.2 friends versus 189.4 followers, p<0.001), and were more likely to report daily use of Facebook versus Twitter (94.6% versus 50%, p<0.001). Current alcohol use was predictive of both Facebook and Twitter displayed alcohol references, but mediators differed in each model. Discussion College students were more likely to display alcohol references on Facebook compared to Twitter. Understanding these patterns and predictors may inform prevention and intervention efforts directed at particular social media sites. PMID:26995291

Research on the use of social networks for health-related purposes is limited. This study aims to characterize the purpose and use of Facebook and Twitter groups concerning colorectal cancer, breast cancer, and diabetes. We searched in Facebook ( www.facebook.com ) and Twitter ( www.twitter.com ) using the terms "colorectal cancer," "breast cancer," and "diabetes." Each important group has been analyzed by extracting its network name, number of members, interests, and Web site URL. We found 216 breast cancer groups, 171 colorectal cancer groups, and 527 diabetes groups on Facebook and Twitter. The largest percentage of the colorectal cancer groups (25.58%) addresses prevention, similarly to breast cancer, whereas diabetes groups are mainly focused on research issues (25.09%). There are more social groups about breast cancer and diabetes on Facebook (around 82%) than on Twitter (around 18%). Regarding colorectal cancer, the difference is less: Facebook had 62.23%, and Twitter 31.76%. Social networks are a useful tool for supporting patients suffering from these three diseases. Regarding the use of these social networks for disease support purposes, Facebook shows a higher usage rate than Twitter, perhaps because Twitter is newer than Facebook, and its use is not so generalized.
Use of New Media by Turkish Fans in Sport Communication: Facebook and Twitter
Özsoy, Selami
2011-01-01
This research examines the use of Facebook and Twitter, two social networks, for sportive reasons in Turkey. To this end, the literature was surveyed and a 5 Likert type data collection tool consisting of 21 questions was developed by the researcher based on the expert views. The sample of the research included 460 sport fans who are college students at Abant İzzet Baysal University and Sakarya University. It was found in the research that 91.7% of the participants had a profile on Facebook and 13.3% had a profile on Twitter. The rate of opening an account on Twitter, which still has no version in Turkish language, was low. It was found that the fans mostly followed the official site of their favorite team on Facebook, got informed about the sports activities through Facebook and learned news, which they did not hear from other sources. It was also ascertained that male fans used social networks for sportive reasons more than female fans did (p<.05). It is possible to state that social networks such as Facebook and Twitter have become a rapidly-developing alternative medium in sports against traditional media such as newspaper and television.

Our objective was to compare the change in research informed knowledge of health professionals and their intended practice following exposure to research information delivered by either Twitter or Facebook. This open label comparative design study randomized health professional clinicians to receive "practice points" on tendinopathy management via Twitter or Facebook. Evaluated outcomes included knowledge change and self-reported changes to clinical practice. Four hundred and ninety-four participants were randomized to 1 of 2 groups and 317 responders analyzed. Both groups demonstrated improvements in knowledge and reported changes to clinical practice. There was no statistical difference between groups for the outcomes of knowledge change (P = .728), changes to clinical practice (P = .11) or the increased use of research information (P = .89). Practice points were shared more by the Twitter group (P < .001); attrition was lower in the Facebook group (P < .001). Research information delivered by either Twitter or Facebook can improve clinician knowledge and promote behavior change. No differences in these outcomes were observed between the Twitter and Facebook groups. Brief social media posts are as effective as longer posts for improving knowledge and promoting behavior change. Twitter may be more useful in publicizing information and Facebook for encouraging course completion. © The Author 2016.

Ophthalmology on social networking sites: an observational study of Facebook, Twitter, and LinkedIn.
Micieli, Jonathan A; Tsui, Edmund
2015-01-01
The use of social media in ophthalmology remains largely unknown. Our aim was to evaluate the extent and involvement of ophthalmology journals, professional associations, trade publications, and patient advocacy and fundraising groups on social networking sites. An archived list of 107 ophthalmology journals from SCImago, trade publications, professional ophthalmology associations, and patient advocacy organizations were searched for their presence on Facebook, Twitter, and LinkedIn. Activity and popularity of each account was quantified by using the number of "likes" on Facebook, the number of followers on Twitter, and members on LinkedIn. Of the 107 journals ranked by SCImago, 21.5% were present on Facebook and 18.7% were present on Twitter. Journal of Community Eye Health was the most popular on Facebook and JAMA Ophthalmology was most popular on Twitter. Among the 133 members of the International Council of Ophthalmology, 17.3% were present on Facebook, 12.8% were present on Twitter, and 7.5% were present on LinkedIn. The most popular on Facebook was the International Council of Ophthalmology, and the American Academy of Ophthalmology was most popular on Twitter and LinkedIn. Patient advocacy organizations were more popular on all sites compared with journals, professional association, and trade publications. Among the top ten most popular pages in each category, patient advocacy groups were most active followed by trade publications, professional associations, and journals. Patient advocacy groups lead the way in social networking followed by professional organizations and journals. Although some journals use social media, most have yet to engage its full potential and maximize the number of potential interested individuals.

Facebook (FB) and Twitter are popular social networking sites. This study examined differences between those who use both sites versus only FB, to test the hypothesis that mono-users differ in their personality characteristics from users active in both websites. Participants were 205 undergraduate students; 96 only used FB, 109 used FB and Twitter. Participants who used both sites reported significantly lower loneliness, higher number of FB friends, and lower number of minutes spent online, as compared to those who only used FB. Loneliness was positively associated with FB use only in those who used FB alone, but was negatively associated with and negatively predicted both FB and Twitter use in those who used both websites. Findings suggest that more intense use of online interactions is more frequently found in mono-users (people using only Facebook) as compared to those using both websites, and it is predicted by increased feelings of loneliness. The current study findings provide additional insights on what personality factors may make some people prone to excessive use of social networking sites. PMID:26997849

Conservation science needs to engage the general public to ensure successful conservation interventions. Although online technologies such as Twitter and Facebook offer new opportunities to accelerate communication between conservation scientists and the online public, factors influencing the spread of conservation news in online media are not well understood. We explored transmission of conservation research through online news articles with generalized linear mixed-effects models and an information theoretic approach. In particular, we assessed differences in the frequency conservation research is featured on online news sites and the impact of online conservation news content and delivery on Facebook likes and shares and Twitter tweets. Five percent of articles in conservation journals are reported in online news, and the probability of reporting depended on the journal. There was weak evidence that articles on climate change and mammals were more likely to be featured. Online news articles about charismatic mammals with illustrations were more likely to be shared or liked on Facebook and Twitter, but the effect of news sites was much larger. These results suggest journals have the greatest impact on which conservation research is featured and that news site has the greatest impact on how popular an online article will be on Facebook and Twitter. © 2015 Society for Conservation Biology.

Social media posts regarding measles vaccination were classified as pro-vaccination, expressing vaccine hesitancy, uncertain, or irrelevant. Spearman correlations with Centers for Disease Control and Prevention-reported measles cases and differenced smoothed cumulative case counts over this period were reported (using time series bootstrap confidence intervals). A total of 58,078 Facebook posts and 82,993 tweets were identified from 4 January 2009 to 27 August 2016. Pro-vaccination posts were correlated with the US weekly reported cases (Facebook: Spearman correlation 0.22 (95% confidence interval: 0.09 to 0.34), Twitter: 0.21 (95% confidence interval: 0.06 to 0.34)). Vaccine-hesitant posts, however, were uncorrelated with measles cases in the United States (Facebook: 0.01 (95% confidence interval: -0.13 to 0.14), Twitter: 0.0011 (95% confidence interval: -0.12 to 0.12)). These findings may result from more consistent social media engagement by individuals expressing vaccine hesitancy, contrasted with media- or event-driven episodic interest on the part of individuals favoring current policy.

Facebook and Twitter, communication and shelter, and the 2011 Tuscaloosa tornado.
Stokes, Courtney; Senkbeil, Jason C
2017-01-01
This paper represents one of the first attempts to analyse the many ways in which Facebook and Twitter were used during a tornado disaster. Comparisons between five randomly selected campus samples and a city of Tuscaloosa, Alabama, sample revealed that campus samples used Facebook and Twitter significantly more both before and after the tornado, but Facebook usage was not significantly different after the event. Furthermore, differences in social media usage and other forms of communication before the tornado were found for age, education, and years lived in Tuscaloosa. Generally, age and education were inversely proportionate to social media usage. Influences on shelter-seeking actions varied between social media users and three random samples of non-social media users; however, it appears that social media respondents were likely to be using a smartphone simultaneously to access warning polygon information, to receive text message alerts, and to listen or respond to environmental cues. © 2017 The Author(s).

This systematic review aims to answer the following question: What is the impact of Twitter and Facebook on nursing practice and education? Any article that was written in English and was published in PubMed and Computers Informatics Nursing (CIN) journal from 2011 up to 2016 and discussed the impact of Twitter and Facebook on nursing practice and education was included, while any opinion and review articles were excluded. The results show three themes that are covered by the literature: (1) using social media to enhance students' confidence and /or self-efficacy, (2) characteristics of nurses who use social media, and (3) preferred modes of communication. Further research is still needed to reveal the impact of Twitter and Facebook on nursing education as well as other specialties of nursing practice.

Background Frequent expression of negative emotion words on social media has been linked to depression. However, metrics have relied on average values, not dynamic measures of emotional volatility. Objective The aim of this study was to report on the associations between depression severity and the variability (time-unstructured) and instability (time-structured) in emotion word expression on Facebook and Twitter across status updates. Methods Status updates and depression severity ratings of 29 Facebook users and 49 Twitter users were collected through the app MoodPrism. The average proportion of positive and negative emotion words used, within-person variability, and instability were computed. Results Negative emotion word instability was a significant predictor of greater depression severity on Facebook (rs(29)=.44, P=.02, 95% CI 0.09-0.69), even after controlling for the average proportion of negative emotion words used (partial rs(26)=.51, P=.006) and within-person variability (partial rs(26)=.49, P=.009). A different pattern emerged on Twitter where greater negative emotion word variability indicated lower depression severity (rs(49)=−.34, P=.01, 95% CI −0.58 to 0.09). Differences between Facebook and Twitter users in their emotion word patterns and psychological characteristics were also explored. Conclusions The findings suggest that negative emotion word instability may be a simple yet sensitive measure of time-structured variability, useful when screening for depression through social media, though its usefulness may depend on the social media platform.

When the Zika virus outbreak became a global health emergency in early 2016, the scientific community responded with an increased output of Zika-related research. This upsurge in research naturally made its way into academic journals along with editorials, news, and reports. However, it is not yet known how or whether these scholarly communications were distributed to the populations most affected by Zika. To understand how scientific outputs about Zika reached global and local audiences, we collected Tweets and Facebook posts that linked to Zika-related research in the first six months of 2016. Using a language detection algorithm, we found that up to 90% of Twitter and 76% of Facebook posts are in English. However, when none of the authors of the scholarly article are from English-speaking countries, posts on both social media are less likely to be in English. The effect is most pronounced on Facebook, where the likelihood of posting in English is between 11 and 16% lower when none of the authors are from English-speaking countries, as compared to when some or all are. Similarly, posts about papers written with a Brazilian author are 13% more likely to be in Portuguese on Facebook than when made on Twitter. Our main conclusion is that scholarly communication on Twitter and Facebook of Zika-related research is dominated by English, despite Brazil being the epicenter of the Zika epidemic. This result suggests that scholarly findings about the Zika virus are unlikely to be distributed directly to relevant populations through these popular online mediums. Nevertheless, there are differences between platforms. Compared to Twitter, scholarly communication on Facebook is more likely to be in the language of an author's country. The Zika outbreak provides a useful case-study for understanding how scientific outputs are communicated to relevant populations. Our results suggest that Facebook is a more effective channel than Twitter, if communication is desired to be in the

To measure the usage rate of social media (SoMe) resources in the prostate cancer community, we performed a comprehensive quantitative and qualitative assessment of SoMe activity on the topic of PCa on the four most frequented platforms. We scanned the SoMe platforms Facebook, Twitter, YouTube, and Instagram for "prostate cancer" as a cross-sectional analysis or during a defined time period. Sources were included if their communication centered on PCa by title and content. We assessed activity measurements for each SoMe source and classified the sources into six functional categories. We identified 99 PCa-related Facebook groups that amassed 31,262 members and 90 Facebook pages with 283,996 "likes". On YouTube, we found 536 PCa videos accounting for 43,966,634 views, 52,655 likes, 8597 dislikes, and 12,393 comments. During a 1-year time period, 32,537 users generated 110,971 tweets on #ProstateCancer on Twitter, providing over 544 million impressions. During a 1-month time period, 638 contributors posted 1081 posts on Instagram, generating over 22,000 likes and 4,748,159 impressions. Among six functional categories, general information/support dominated the SoMe landscape on all SoMe platforms. SoMe activity on the topic of PCa on the four most frequented platforms is high. Facebook groups, YouTube videos, and Twitter tweets are mainly used for giving general information on PCa and education. High SoMe utilization in the PCa community underlines its future role for communication of PCa.

Social networking has become a part of daily life for most people. In the era of globalization, it has become indispensable for effective communication between friends and peers across the world. Today, social media use is not restricted only to our personal lives; it is becoming increasingly incorporated into our professional lives, as well. Social media platforms are rapidly becoming a necessary tool for medical professionals. Apt use of social media platforms can revolutionize scientific communication and collaboration. Pathologists are increasingly counted among Facebook's 2 billion users and Twitter's 328 million members. Social media can be a powerful tool not only for individual career progression but also for raising the public profile of the specialty of pathology. It is now possible for us to reach out to millions of people, simultaneously and instantaneously, just by touching a screen. Real-time interactions between physicians, across geographic borders and subspecialty borders, will undeniably open unexplored avenues for effective communication, consultation, research collaboration, and education. Knowledge sharing through social media will immensely enrich and grow our careers as pathologists; it will also enlighten the public and physicians of other specialties as to the crucial role of pathologists in patient care. We discuss the uses of Facebook and Twitter in modern day pathology, its implication in routine daily practice, pros and cons, and tips for effective social media use by pathologists.

The Web 2.0 has democratized the use of services and applications, being Facebook and Twitter its leading exponents and it even has been proposed that there exists a Medicine 2.0. A survey for professionals subscribed to discussion lists of Argentine Pediatric Society (SAP) and for visitors to the Website was carried out to know the use of Web 2.0. In 377 responses (76% pediatricians), 81.3% of users use Facebook and Twitter 16.5%. Facebook is used in an 85% for personal purposes, while the professional use of it is 41.2%. Pediatricians frequently use other web 2.0 applications such as YouTube (80.3%), sharing images (52.2%) and listening to Podcasts (34.8%). Around 50% of the professionasl surveyed showed interest in receiving information on the professional activites carried out by SAP. Clinicians should recognize these new tools to incorporate them into their professional activities.

Social media interactions can inform public health risk perceptions. While research has examined the risk relationships between obesity and cancer, public attitudes about their associations remain largely unknown. We explored how these constructs were discussed together on two social media platforms. Publicly accessible Facebook and Twitter posts from a 2-month period in 2012 containing references to obesity ("obese/obesity," "overweight," and "fat") and cancer-related words were extracted (N = 3702 posts). Data cleaning yielded a final set of 1382 posts (Facebook: N = 291; Twitter: N = 1091). Using a mixed-methods approach, themes were inductively generated, and sentiment valence, structural elements, and epistemic stance were coded. Seven relational themes emerged: obesity is associated with cancer (n = 389), additional factors are associated with both obesity and cancer (n = 335), obesity causes cancer (n = 85), cancer causes obesity (n = 6), obesity is not linked to cancer (n = 13), co-occurrence (n = 492), and obesity is valued differently than cancer (n = 60). Fifty-nine percent of posts focused on an associative or causal link between obesity and cancer. Thirty-one percent of posts contained positive and/or negative sentiment. Facebook was more likely to contain any sentiment, but Twitter contained proportionately more negative sentiment. Concurrent qualitative analysis revealed a dominance of individual blame for overweight/obese persons and more support and empathy for cancer survivors. Our study reflects wide recognition of the evidence linking obesity to increased risk of cancer, a diverse set of factors perceived to be dually associated with both conditions and differing attribution of responsibility. We demonstrate that social media monitoring can provide an important gauge of public health risk perception.
Let's Have a Tweetup: The Case for Using Twitter Professionally.
Fuller, Maren Y; Allen, Timothy Craig
2016-09-01
Social media use is very common and can be an effective way for professionals to discuss information and interact with colleagues. Twitter (Twitter, Inc, San Francisco, California) is a social media network where posts, termed tweets, are limited to 140 characters. Professional use of Twitter is ideal for physicians interested in both networking and education and is optimally used to facilitate in-person networking. Live-tweeting (posting real-time reactions to events) at professional meetings is also a popular and highly successful use of Twitter. Physicians report patient privacy as the top concern preventing use of social media for professional reasons, and although generally social media use is safe, it is essential to understand how to protect patient confidentially. Other social media platforms with potential for professional use include Facebook (Facebook, Inc, Menlo Park, California), Instagram (Facebook, Inc), YouTube (YouTube, LLC, San Bruno, California), and Periscope (Twitter, Inc). With Twitter and other social media options, now is the time for pathologists to increase our visibility on social media and worldwide.

Despite increasing evidence that specific types of Facebook use (i.e., active private, active public, and passive Facebook use) are differently related to adolescents' well-being, little is known how these types function over the course of adolescence and whether gender and Facebook motives may predict the initial level and changes in these types over time. To address these gaps, Flemish adolescents (ages 12-19) were questioned at three different time points, with six months in between (NTime1 = 1866). Latent growth curve models revealed that active private Facebook use increased over the course of adolescence, whereas public Facebook use decreased. Passive Facebook use, however, remained stable. In addition, gender and Facebook motives were related to initial levels of specific types of Facebook use, and predictive of dynamic change in specific types of Facebook use over time. The discussion focuses on the understanding and implications of these findings. Copyright © 2016. Published by Elsevier Ltd.

This paper seeks to purpose the concept of Twitter marketing methods. The tools that Twitter provides are modelled and simulated using iThink in the context of a Twitter media-marketing agency. The paper has leveraged the system's dynamic paradigm to conduct Facebook marketing tools and methods modelling, using iThink™ system to implement them. It uses the design science research methodology for the proof of concept of the models and modelling processes. The following models have been developed for a twitter marketing agent/company and tested in real circumstances and with real numbers. These models were finalized through a number of revisions and iterators of the design, develop, simulate, test and evaluate. It also addresses these methods that suit most organized promotion through targeting, to the Twitter social media service. The validity and usefulness of these Twitter marketing methods models for the day-to-day decision making are authenticated by the management of the company organization. It implements system dynamics concepts of Twitter marketing methods modelling and produce models of various Twitter marketing situations. The Tweet method that Twitter provides can be adjusted, depending on the situation, in order to maximize the profit of the company/agent.
Facebook and Edublogs and Twitter, Oh My! Using Social Media to Connect Scientists to the Public

Social media is changing the way that the public receives and responds to news and information. By integrating technology, social interaction and the construction of words and pictures, social media creates multidirectional communication pathways that allow people to directly interact with the purveyors of information. Social media forums (e.g., Edublogs, Facebook, Second Life, and Twitter) are increasingly used by scientists and science programs to directly connect with the public, eliminating the "filter" of the news media. This creates both opportunities and challenges for scientists wanting to make sure that accurate information is reaching their audience. Here we talk about how NASA missions and programs have been using social media as an outreach tool and how social media can be used to bring authentic science to the public.

Corpus-based word frequencies are one of the most important predictors in language processing tasks. Frequencies based on conversational corpora (such as movie subtitles) are shown to better capture the variance in lexical decision tasks compared to traditional corpora. In this study, we show that frequencies computed from social media are currently the best frequency-based estimators of lexical decision reaction times (up to 3.6% increase in explained variance). The results are robust (observed for Twitter- and Facebook-based frequencies on American English and British English datasets) and are still substantial when we control for corpus size. © 2016 The Authors.

Reality television programming is a popular type of television programming, and features shows about cosmetic surgery. Social media such as Facebook and Twitter are increasingly popular methods of sharing information. The authors surveyed college students to determine among those watching reality television cosmetic surgery programs whether perceived realism or social media use was associated with attitudes toward cosmetic surgery. Participants (n=126) were surveyed about their reality television cosmetic surgery program viewing habits, their perception of the realism of reality television programming, and social media topics of Twitter and Facebook. Outcome variables were the Acceptance of Cosmetic Surgery Scales of social, intrapersonal, and consider. Perceived realism was significantly associated with increased scores on the Acceptance of Cosmetic Surgery Scale subscales of social (p=0.004), intrapersonal (p=0.03), and consider (p=0.03). Following a character from a reality television program on Twitter was significantly associated with increased social scores (p=0.04). There was no significant association of Facebook behavior with attitudes toward cosmetic surgery. Cosmetic plastic surgeons may benefit by advertising their services on cosmetic surgery reality television programs. These reality television programs portray cosmetic surgery in a positive manner, and viewers with increased perceived realism will be a potential receptive audience toward such advertising. Also, advertising cosmetic surgery services on Twitter feeds that discuss cosmetic surgery reality television programs would be potentially beneficial.

Twitmographics: Learning the Emergent Properties of the Twitter Community

Cheong, Marc; Lee, Vincent
This paper presents a framework for discovery of the emergent properties of users of the Twitter microblogging platform. The novelty of our methodology is the use of machine-learning methods to deduce user demographic information and online usage patterns and habits not readily apparent from the raw messages posted on Twitter. This is different from existing social network analysis performed on de facto social networks such as Face-book, in the sense that we use publicly available metadata from Twitter messages to explore the inherent characteristics about different segments of the Twitter community, in a simple yet effective manner. Our framework is coupled with the self-organizing map visualization method, and tested on a corpus of messages which deal with issues of socio politi-cal and economic impact, to gain insight into the properties of human interaction via Twitter as a medium for computer-mediated self-expression.
The effect of Twitter exposure on false memory formation.
Fenn, Kimberly M; Griffin, Nicholas R; Uitvlugt, Mitchell G; Ravizza, Susan M
2014-12-01
Social media sites such as Facebook and Twitter have increased drastically in popularity. However, information on these sites is not verified and may contain inaccuracies. It is well-established that false information encountered after an event can lead to memory distortion. Therefore, social media may be particularly harmful for autobiographical memory. Here, we tested the effect of Twitter on false memory. We presented participants with a series of images that depicted a story and then presented false information about the images in a scrolling feed that bore either a low or high resemblance to a Twitter feed. Confidence for correct information was similar across the groups, but confidence for suggested information was significantly lower when false information was presented in a Twitter format. We propose that individuals take into account the medium of the message when integrating information into memory.

Fifty-one interviews with women in planetary science are now available as an e-mentoring and teaching resource on WomeninPlanetaryScience.com. Each scientist was nominated and interviewed by a fellow member of the planetary science community, and each gladly shared her advice for advancement in the field. Women in Planetary Science was founded in 2008 to connect communities of current and prospective scientists, to promote proposal and award opportunities, and to stimulate discussion in the planetary science community at large. Regular articles, or posts, by nearly a dozen collaborators highlight a range of current issues for women in this field. These articles are promoted by collaborators on Twitter, Facebook, and Google+ and shared again by the collaborators' contacts, reaching a significantly wider audience. The group's latest project, on Pinterest, is a crowd-sourced photo gallery of more than 350 inspiring women in planetary science; each photo links to the scientist's CV. The interviews, the essays, and the photo gallery are available online as resources for prospective scientists, planetary scientists, parents, and educators.
Psychiatrists' Perceptions of Facebook and Other Social Media.

2015-12-01
The literature has seen a surge in research on the mental health impacts of technologies such as Facebook, Twitter and other social media, but little is known regarding how mental health workers perceive patients and clients who report use of such technologies. The present study examines how psychiatrists perceive social media and whether they make use of it. Psychiatrists (N = 48) at a tertiary care centre in Canada completed a questionnaire assessing history of using social networking sites (SNSs) such as Facebook and Google Plus and status update sites (SUSs) such as Twitter and Livejournal and whether they associate them with psychopathology. 38.5 % have used SNSs and 9.8 % have used SUSs. Only 37 % believed there was an association between psychopathology and SNSs while 33 % believed there was an association between psychopathology and SUSs. Implications for clinical practice and future research are discussed.
On Quantifying Diffusion of Health Information on Twitter.
Bakal, Gokhan; Kavuluru, Ramakanth
2017-02-01
With the increasing use of digital technologies, online social networks are emerging as major means of communication. Recently, social networks such as Facebook and Twitter are also being used by consumers, care providers (physicians, hospitals), and government agencies to share health related information. The asymmetric user network and the short message size have made Twitter particularly popular for propagating health related content on the Web. Besides tweeting on their own, users can choose to retweet particular tweets from other users (even if they do not follow them on Twitter.) Thus, a tweet can diffuse through the Twitter network via the follower-friend connections. In this paper, we report results of a pilot study we conducted to quantitatively assess how health related tweets diffuse in the directed follower-friend Twitter graph through the retweeting activity. Our effort includes (1). development of a retweet collection and Twitter retweet graph formation framework and (2). a preliminary analysis of retweet graphs and associated diffusion metrics for health tweets. Given the ambiguous nature (due to polysemy and sarcasm) of health relatedness of tweets collected with keyword based matches, our initial study is limited to ≈ 200 health related tweets (which were manually verified to be on health topics) each with at least 25 retweets. To our knowledge, this is first attempt to study health information diffusion on Twitter through retweet graph analysis.
Facebook use and its relationship with sport anxiety.
Encel, Kim; Mesagno, Christopher; Brown, Helen
2017-04-01
Social media (e.g., Facebook and Twitter) use has increased considerably since its inception; however, research examining the relationship between social media use and sport has not progressed as rapidly. The purpose of the current study was to explore the prevalence rates of Facebook use among athletes around and during sport competitions and to investigate the relationships between sport anxiety and Facebook use. Two hundred and ninety-eight athletes of varying levels completed measures for sport anxiety and Facebook use, which included descriptive information about Facebook use prior to, during and following competitions. Results indicated that 31.9% of athletes had used Facebook during a competition and 68.1% had accessed Facebook within 2 h prior to competition. Time spent on Facebook prior to competition was significantly (and positively) correlated with the concentration disruption component of sport anxiety. Furthermore, regression analyses revealed that having push notifications enabled on an athletes' phone predicted 4.4% of the variability in sport anxiety. The percentage of athletes who accessed Facebook within 2 h of, or during, a competition is somewhat alarming considering the importance of psychological preparation in sport, which may compromise optimal psychological readiness and may lead to increased sport anxiety.

Type D personality, stress coping strategies and self-efficacy as predictors of Facebook intrusion.
Błachnio, Agata; Przepiorka, Aneta; Czuczwar, Stanisław Jerzy
2017-07-01
Recently, Facebook has become one of the most popular social networking sites. People use it more and more often. A number of studies have recently addressed the issue of excessive Facebook use, showing this phenomenon to be a spreading problem. The main aim of the present study was to examine whether Type D personality, self-efficacy and coping strategies are related to Facebook intrusion. The participants were 882 students of Polish universities, all of them Facebook users (72% women, mean age: 22.25 years, SD =2.06). We used the Facebook Intrusion Questionnaire, the Facebook Intensity Scale, the General Self-Efficacy Scale, the Coping Inventory for Stressful Situations, and the Type D Scale. We applied the pen-and-paper procedure. Our results indicate that emotion-oriented and avoidance-oriented strategies of coping in stressful situations are predictors of Facebook intrusion and Facebook intensity. The relations between both Facebook intrusion and intensity and social inhibition are significant only when emotion-oriented coping strategy is controlled. The knowledge of whether coping strategies in stressful situations, such as focus on emotions or avoidance, are related to Facebook intrusion might be useful for clinical purposes.

Two Types of Well Followed Users in the Followership Networks of Twitter
Saito, Kodai; Masuda, Naoki
2014-01-01
In the Twitter blogosphere, the number of followers is probably the most basic and succinct quantity for measuring popularity of users. However, the number of followers can be manipulated in various ways; we can even buy follows. Therefore, alternative popularity measures for Twitter users on the basis of, for example, users' tweets and retweets, have been developed. In the present work, we take a purely network approach to this fundamental question. First, we find that two relatively distinct types of users possessing a large number of followers exist, in particular for Japanese, Russian, and Korean users among the seven language groups that we examined. A first type of user follows a small number of other users. A second type of user follows approximately the same number of other users as the number of follows that the user receives. Then, we compare local (i.e., egocentric) followership networks around the two types of users with many followers. We show that the second type, which is presumably uninfluential users despite its large number of followers, is characterized by high link reciprocity, a large number of friends (i.e., those whom a user follows) for the followers, followers' high link reciprocity, large clustering coefficient, large fraction of the second type of users among the followers, and a small PageRank. Our network-based results support that the number of followers used alone is a misleading measure of user's popularity. We propose that the number of friends, which is simple to measure, also helps us to assess the popularity of Twitter users. PMID:24416209
Young Adults' Exposure to Alcohol- and Marijuana-Related Content on Twitter.

2016-03-01
Twitter is among the most popular social media platforms used by young adults, yet it has been underutilized in substance use research compared with older platforms (e.g., MySpace and Facebook). We took a first step toward studying the associations between exposure to pro-alcohol- and marijuana-related content among young adults via Twitter and current heavy episodic drinking and current marijuana use, respectively. We conducted an online survey of 587 (254 men, 333 women) Twitter users between ages 18 and 25 years in February 2014 using an online survey system that has been previously used in research on health behaviors and attitudes. Current heavy episodic drinking was significantly associated with higher levels of exposure to pro-alcohol content. Similarly, current marijuana use was significantly associated with higher levels of exposure to pro-marijuana content. Our findings suggest that in-depth research regarding young adults' exposure to pro-alcohol- and marijuana-related content via Twitter may provide a foundation for developing effective prevention messages on this social media platform to counter the pro-alcohol and marijuana messages.

Social networks produce an enormous quantity of data. Facebook consists of over 400 million active users sharing over 5 billion pieces of information each month. Analyzing this vast quantity of unstructured data presents challenges for software and hardware. We present GraphCT, a Graph Characterization Tooklit for massive graphs representing social network data. On a 128-processor Cray XMT, GraphCT estimates the betweenness centrality of an artificially generated (R-MAT) 537 million vertex, 8.6 billion edge graph in 55 minutes. We use GraphCT to analyze public data from Twitter, a microblogging network. Twitter's message connections appear primarily tree-structured as a news dissemination system.more » Within the public data, however, are clusters of conversations. Using GraphCT, we can rank actors within these conversations and help analysts focus attention on a much smaller data subset.« less
Twitter and the health reforms in the English National Health Service.
King, Dominic; Ramirez-Cano, Daniel; Greaves, Felix; Vlaev, Ivo; Beales, Steve; Darzi, Ara
2013-05-01
Social media (for example Facebook and YouTube) uses online and mobile technologies to allow individuals to participate in, comment on and create user-generated content. Twitter is a widely used social media platform that lets users post short publicly available text-based messages called tweets that other users can respond to. Alongside traditional media outlets, Twitter has been a focus for discussions about the controversial and radical reforms to the National Health Service (NHS) in England that were recently passed into law by the current coalition Government. Looking at over 120,000 tweets made about the health reforms, we have investigated whether any insights can be obtained about the role of Twitter in informing, debating and influencing opinion in a specific area of health policy. In particular we have looked at how the sentiment of tweets changed with the passage of the Health and Social Care Bill through Parliament, and how this compared to conventional opinion polls taken over the same time period. We examine which users appeared to have the most influence in the 'Twittersphere' and suggest how a widely used metric of academic impact - the H-index - could be applied to measure context-dependent influence on Twitter.

This article aims to characterize the different types of Facebook and Twitter groups for different mental diseases, their purposes, and their functions. We focused the search on depressive disorders, dementia, and Alzheimer's and Parkinson's diseases and examined the Facebook (www.facebook.com) and Twitter (www.twitter.com) groups. We used four assessment criteria: (1) purpose, (2) type of creator, (3) telehealth content, and (4) free-text responses in surveys and interviews. We observed a total of 357 Parkinson groups, 325 dementia groups, 853 Alzheimer groups, and 1127 depression groups on Facebook and Twitter. Moreover, we analyze the responses provided by different users. The survey and interview responses showed that many people were interested in using social networks to support and help in the fight against these diseases. The results indicate that social networks are acceptable by users in terms of simplicity and utility. People use them for finding support, information, self-help, advocacy and awareness, and for collecting funds. © The Author(s) 2014.

Social networking sites (SNS) are now part of everyday life, and SNSs such as Facebook, YouTube, and Twitter are among the most accessed Web sites on the Internet. Although SNSs are primarily used for staying in touch with friends and family, they are increasingly being used for health-related purposes for a variety of conditions, including concussion awareness. As health interventions begin to be more commonly provided through SNSs (particularly Facebook), ethical issues have been raised with regard to confidentiality, privacy, and trust; these issues need to be addressed. This article outlines some of the key considerations when providing a concussion intervention through Facebook and discusses potential solutions to these issues.

Americans are increasingly using social media (such as Facebook, YouTube, and Twitter) for health-related communication. Much of the previous research on social media and health communication has focused on Facebook groups related to a specific disease or Facebook pages related to an advocacy organization. Less is known about how people communicate about cancer on personal Facebook pages. In this study, we expand upon previous research by examining how cancer caregivers use personal Facebook pages for cancer-related communication. We examined themes in cancer-related exchanges through a content analysis of 12 months of data from 18 publically available Facebook pages hosted by parents of children with acute lymphoblastic leukemia (15 852 total posts). Six themes emerged: (1) documenting the cancer journey, (2) sharing emotional strain associated with caregiving, (3) promoting awareness and advocacy about pediatric cancer, (4) fundraising, (5) mobilizing support, and (6) expressing gratitude for support. Building upon previous research documenting the increasing use of social media for health-related communication and support, our findings show that personal Facebook pages offer a platform for cancer caregivers to share their cancer-related experiences, promote advocacy and awareness, and mobilize social support. Providers must recognize the importance of social media as a vehicle for support and communication for families of children with cancer. Nurses should educate parents on how to appraise information obtained through Facebook using evidence-based guidelines. Providers can encourage caregivers to use Facebook as a tool for communication, information, and support.
True and fake information spreading over the Facebook

Social networks have involved more and more users who search for and share information extensively and frequently. Tremendous evidence in Facebook, Twitter, Flickr and Google+ alike shows that such social networks are the major information sources as well as the most effective platforms for information transmission and exchange. The dynamic propagation of various information may gradually disseminate, drastically increase, strongly compete with each other, or slowly decrease. These observations had led to the present study of the spreading process of true and fake information over social networks, particularly the Facebook. Specifically, in this paper the topological structure of two huge-scale Facebook network datasets are investigated regarding their statistical properties. Based on that, an information model for simulating the true and fake information spreading over the Facebook is established. Through controlling the spreading parameters in extensive large-scale simulations, it is found that the final density of stiflers increases with the growth of the spreading rate, while it would decline with the increase of the removal rate. Moreover, it is found that the spreading process of the true-fake information is closely related to the node degrees on the network. Hub-individuals with high degrees have large probabilities to learn hidden information and then spread it. Interestingly, it is found that the spreading rate of the true information but not of the fake information has a great effect on the information spreading process, reflecting the human nature in believing and spreading truths in social activities. The new findings validate the proposed model to be capable of characterizing the dynamic evolution of true and fake information over the Facebook, useful and informative for future social science studies.

Social network services (e.g., Twitter and Facebook) can be regarded as social sensors which can capture a number of events in the society. Particularly, in terms of time and space, various smart devices have improved the accessibility to the social network services. In this paper, we present a social software platform to detect a number of meaningful events from information diffusion patterns on such social network services. The most important feature is to process the social sensor signal for understanding social events and to support users to share relevant information along the social links. The platform has been applied to fetch and cluster tweets from Twitter into relevant categories to reveal hot topics.

Affordances refer to how interface features of an IT artifact, perceived by its users in terms of their potentials for action, may predict the intensity of usage. This study investigates three social information affordances for expressive information control, privacy information control, and image information control in Facebook. The results show that the three affordances can significantly explain how Facebook's interface designs facilitate users' self-presentation activities. In addition, the findings reveal that males are more engaged in expressing information than females, while females are more involved in privacy control than males. A practical application of our study is to compare and contrast the level of affordances offered by various social network sites (SNS) like Facebook and Twitter, as well as differences in online self-presentations across cultures. Our approach can therefore be useful to investigate how SNS design features can be tailored to specific gender and culture needs.
Evaluating the use of twitter as a tool to increase engagement in medical education.
Diug, Basia; Kendal, Evie; Ilic, Dragan

Social media is regularly used by undergraduate students. Twitter has a constant feed to the most current research, news and opinions of experts as well as organisations. Limited evidence exists that examines how to use social media platforms, such as Twitter, effectively in medical education. Furthermore, there is limited evidence to inform educators regarding social media's potential to increase student interaction and engagement. To evaluate whether social media, in particular Twitter, can be successfully used as a pedagogical tool in an assessment to increase student engagement with staff, peers and course content. First year biomedical science students at Monash University completing a core public health unit were recruited into the study. Twitter-related activities were incorporated into the semester long unit and aligned with both formative and summative assessments. Students completed a structured questionnaire detailing previous use of social media and attitudes towards its use in education post engagement in the Twitter-specific activities. Likert scale responses compared those who participated in the Twitter activities with those who did not using student's t-test. A total of 236 (79.4%) of invited students participated in the study. Among 90% of students who reported previous use of social media, 87.2% reported using Facebook, while only 13.1% reported previous use of Twitter. Social media was accessed most commonly through a mobile device (49.1%). Students actively engaging in Twitter activities had significantly higher end-of-semester grades compared with those who did not [Mean Difference (MD) = 3.98, 95% CI 0.40, 7.55]. Students perceived that the use of Twitter enabled greater accessibility to staff, was a unique method of promoting public health, and facilitated collaboration with peers. Use of social media as an additional, or alternate, teaching intervention is positively supported by students. Specific use of micro-blogs such as Twitter can
Fine social aspiration: Twitter as a voice for cytopathology.
Lepe, M; Gardner, J M
2017-08-01
Social media is an influential tool that has the power to transform cytopathology. Twitter is being used more and more to share cutting-edge updates from pathology meetings ("live-tweeting"). Modern smartphones can now take high resolution microscopic photographs and easily transmit them worldwide via Twitter, Facebook, and other social media, allowing cytopathologists to share educational pearls and discuss difficult cases on a global scale like never before. Social media also allows cytopathologists to share a behind-the-scenes look at their subspecialty with other physicians and even the non-medical public, helping them to better understand the crucial importance of cytopathology in modern medicine. This could positively impact rapport with other specialties, influence policy making, and possibly even improve delivery of patient care. Rare disease patient communities are being formed by patients on Facebook. By joining and volunteering with these patient groups, cytopathologists would have further opportunity to interact directly with patients and their family members, explaining the role of cytopathology in patient care and helping patients to better understand their own diseases. Social media enables cytopathologists and their colleagues in other pathology subspecialties to easily and rapidly form a broad and diverse worldwide network with one another. The authors believe that this is the key to a bright future for our specialty, a strong unified global community of pathologists all working together for education, patient advocacy, and outstanding patient care. Social media can allow us to build that community, strengthen its bonds, and harness its power like never before in history. Diagn.

The study of commuters' origins and destinations (O_D) promises to assist transportation planners with prediction models to inform decision making. Conventionally OD surveys are undertaken through travel surveys and traffic counts, however data collection for these surveys has historically proven to be time consuming and having a strain on human resources, thus a need for an alternative data source arises. This study combines the use social media data and geographic information systems in the creation of a model for origin and destination surveys. The model tests the potential of using big data from Echo echo software which contains Twitter and Facebook data obtained from social media users in Gauteng. This data contains geo-location and it is used to determine origin and destination as well as concentration levels of Gautrain commuters. A kriging analysis was performed on the data to determine the O-D and concentration levels of Gautrain users. The results reveal the concentration of Gautrain commuters at various points of interest that is where they work, live or socialise. The results from the study highlight which nodes attract the most commuters and also possible locations for the expansion for Gautrain. Lastly, the study also highlights some weakness of crowdsourced data for informing transportation planning.

Recent surge of social networking websites in the world supports a widely accepted assumption that people aspires to be recognized online by sharing information with others, perceive enjoyment and keeps to use their social networking site continuously. Different from traditional social networking sites (SNSs) like Cyworld and Facebook, Twitter is famous for its short message and ease of sharing knowledge with others in a prompt manner. Therefore, Twitter is preferred most by many people who seem innovative generically. In this sense, Twitter accumulates its fame as the most influential SNS media among users. However, there is no study to investigate why people holds continuous intention to use the Twitter from the perspective of knowledge-sharing and social presence. To resolve this research issue, this paper adopts six constructs such as personal innovativeness, knowledge-sharing intention, perceived ease of use, perceived enjoyment, social presence, and intention to continuously use. Empirical results with 105 valid questionnaires revealed that the proposed research model is statistically significant, and people's intention to use the Twitter continuously is influenced by social presence, perceived enjoyment, and perceived ease of use.

Good communication is a fundamental step for the spread of news and knowledge. The effectiveness and persuasiveness of a message is a function of the interaction of characteristics of the audience, the source of the message, and content of the message. Italian Research Institute for the Hydrogeological Protection (CNR-IRPI) has been publishing information on geo-hydrological events using the Internet (http://sici.irpi.cnr.it/, http://webmap.irpi.cnr.it/, http://geomorphology.irpi.cnr.it/, http://polaris.irpi.cnr.it/, http://giida.irpi.cnr.it/, http://events.irpi.cnr.it/ ). Our websites are mainly visited by experts and the information are used for technical purposes. The contents and the interface of the websites are designed for this type of users. Our intention is to increase the type of users, and we are testing the use of social network to catch the wide public's attention. Social networks have emerged as critical factor in information dissemination, search, marketing expertise and influence discovery, and are an important channel for people to share information. Social scientist have long recognized the importance of social networks in the spread of information. Facebook and Twitter are the most widely used social networking services. They make it simpler to communicate with multiple people at one time. Social media may also make it easier for users to monitor activities of people (friends or followers). An official Facebook page of the Italian Research Institute for the Hydrogeological Protection (CNR-IRPI, https://www.facebook.com/CNR.IRPI ), was created and linked to a Twitter account. The purpose of this page is to disseminate information on flood and landslide events and on our research activities, in order to raise awareness of geo-hydrological matters among users. This page publishes news on current or historical landslide and flood events involving the Italian territory, or news from around the world collected on the network. The news are published as

The aim of this study was to evaluate use of the microblogging social network Twitter by academic radiology departments (ARDs) in the United States. Twitter was searched to identify all accounts corresponding with United States ARDs. All original tweets from identified accounts over a recent 3-month period (August to October 2014) were archived. Measures of account activity, as well as tweet and link content, were summarized. Fifteen ARDs (8.2%) had Twitter accounts. Ten (5.5%) had "active" accounts, with ≥1 tweet over the 3-month period. Active accounts averaged 711 ± 925 followers (maximum, 2,885) and 61 ± 93 tweets (maximum, 260) during the period. Among 612 tweets from active accounts, content most commonly related to radiology-related education (138), dissemination of departmental research (102), general departmental or hospital promotional material (62), departmental awards or accomplishments (60), upcoming departmental lectures (59), other hospital-related news (55), medical advice or information for patients (38), local community events or news (29), social media and medicine (27), and new departmental or hospital hires or expansion (19). Eighty percent of tweets (490 of 612) included 315 unique external links. Most frequent categories of link sources were picture-, video-, and music-sharing websites (89); the ARD's website or blog (83); peer-reviewed journal articles (40); the hospital's or university's website (34), the lay press (28), and Facebook (14). Twitter provides ARDs the opportunity to engage their own staff members, the radiology community, the department's hospital, and patients, through a broad array of content. ARDs frequently used Twitter for promotional and educational purposes. Because only a small fraction of ARDs actively use Twitter, more departments are encouraged to take advantage of this emerging communication tool. Copyright © 2015 American College of Radiology.

2018-01-01
Although counts of tweets citing academic papers are used as an informal indicator of interest, little is known about who tweets academic papers and who uses Twitter to find scholarly information. Without knowing this, it is difficult to draw useful conclusions from a publication being frequently tweeted. This study surveyed 1,912 users that have tweeted journal articles to ask about their scholarly-related Twitter uses. Almost half of the respondents (45%) did not work in academia, despite the sample probably being biased towards academics. Twitter was used most by people with a social science or humanities background. People tend to leverage social ties on Twitter to find information rather than searching for relevant tweets. Twitter is used in academia to acquire and share real-time information and to develop connections with others. Motivations for using Twitter vary by discipline, occupation, and employment sector, but not much by gender. These factors also influence the sharing of different types of academic information. This study provides evidence that Twitter plays a significant role in the discovery of scholarly information and cross-disciplinary knowledge spreading. Most importantly, the large numbers of non-academic users support the claims of those using tweet counts as evidence for the non-academic impacts of scholarly research.

Stunning imagery helps make astronomy one of the most popular sciences -- but what types of astronomy images are most popular? To help answer this question, public response to images posted to various public venues of the Astronomy Picture of the Day (APOD) are investigated. APOD portals queried included the main NASA website and the social media mirrors on Facebook, Google Plus, and Twitter. Popularity measures include polls, downloads, page views, likes, shares, and retweets; these measures are used to assess how image popularity varies in relation to various image attributes including topic and topicality.

Social media engagement analysis of U.S. Federal health agencies on Facebook.
Bhattacharya, Sanmitra; Srinivasan, Padmini; Polgreen, Philip
2017-04-21
It is becoming increasingly common for individuals and organizations to use social media platforms such as Facebook. These are being used for a wide variety of purposes including disseminating, discussing and seeking health related information. U.S. Federal health agencies are leveraging these platforms to 'engage' social media users to read, spread, promote and encourage health related discussions. However, different agencies and their communications get varying levels of engagement. In this study we use statistical models to identify factors that associate with engagement. We analyze over 45,000 Facebook posts from 72 Facebook accounts belonging to 24 health agencies. Account usage, user activity, sentiment and content of these posts are studied. We use the hurdle regression model to identify factors associated with the level of engagement and Cox proportional hazards model to identify factors associated with duration of engagement. In our analysis we find that agencies and accounts vary widely in their usage of social media and activity they generate. Statistical analysis shows, for instance, that Facebook posts with more visual cues such as photos or videos or those which express positive sentiment generate more engagement. We further find that posts on certain topics such as occupation or organizations negatively affect the duration of engagement. We present the first comprehensive analyses of engagement with U.S. Federal health agencies on Facebook. In addition, we briefly compare and contrast findings from this study to our earlier study with similar focus but on Twitter to show the robustness of our methods.

Data concerning patients originates from a variety of sources on social media. The aim of this study was to show how methodologies borrowed from different areas including computer science, econometrics, statistics, data mining, and sociology may be used to analyze Facebook data to investigate the patients' perspectives on a given medical prescription. To shed light on patients' behavior and concerns, we focused on Crohn's disease, a chronic inflammatory bowel disease, and the specific therapy with the biological drug Infliximab. To gain information from the basin of big data, we analyzed Facebook posts in the time frame from October 2011 to August 2015. We selected posts from patients affected by Crohn's disease who were experiencing or had previously been treated with the monoclonal antibody drug Infliximab. The selected posts underwent further characterization and sentiment analysis. Finally, an ethnographic review was carried out by experts from different scientific research fields (eg, computer science vs gastroenterology) and by a software system running a sentiment analysis tool. The patient feeling toward the Infliximab treatment was classified as positive, neutral, or negative, and the results from computer science, gastroenterologist, and software tool were compared using the square weighted Cohen's kappa coefficient method. The first automatic selection process returned 56,000 Facebook posts, 261 of which exhibited a patient opinion concerning Infliximab. The ethnographic analysis of these 261 selected posts gave similar results, with an interrater agreement between the computer science and gastroenterology experts amounting to 87.3% (228/261), a substantial agreement according to the square weighted Cohen's kappa coefficient method (w2K=0.6470). A positive, neutral, and negative feeling was attributed to 36%, 27%, and 37% of posts by the computer science expert and 38%, 30%, and 32% by the gastroenterologist, respectively. Only a slight agreement was

Significance of likes: Analysing passive interactions on Facebook during campaigning
2017-01-01
With more and more political candidates using social media for campaigning, researchers are looking at measuring the effectiveness of this medium. Most research, however, concentrates on the bare count of likes (or twitter mentions) in an attempt to correlate social media presence and winning. In this paper, we propose a novel method, Interaction Strength Plot (IntS) to measure the passive interactions between a candidate’s posts on Facebook and the users (liking the posts). Using this method on original Malaysian General Election (MGE13) and Australian Federal Elections (AFE13) Facebook Pages (FP) campaign data, we label an FP as performing well if both the posting frequency and the likes gathered are above average. Our method shows that over 60% of the MGE13 candidates and 85% of the AFE13 candidates studied in this paper had under-performing FP. Some of these FP owners would have been identified as popular based on bare count. Thus our performance chart is a vital step forward in measuring the effectiveness of online campaigning.

Despite reported benefits, many women do not attend breast cancer support groups. Abundant online resources for support exist, but information regarding the effectiveness of participation is lacking. We report the results of a Twitter breast cancer support community participant survey. The aim was to determine the effectiveness of social media as a tool for breast cancer patient education and decreasing anxiety. The Breast Cancer Social Media Twitter support community (#BCSM) began in July 2011. Institutional review board approval with a waiver of informed consent was obtained for a deidentified survey that was posted for 2 weeks on Twitter and on the #BCSM blog and Facebook page. There were 206 respondents to the survey. In all, 92.7% (191/206) were female. Respondents reported increased knowledge about breast cancer in the following domains: overall knowledge (80.9%, 153/189), survivorship (85.7%, 162/189), metastatic breast cancer (79.4%, 150/189), cancer types and biology (70.9%, 134/189), clinical trials and research (66.1%, 125/189), treatment options (55.6%, 105/189), breast imaging (56.6%, 107/189), genetic testing and risk assessment (53.9%, 102/189), and radiotherapy (43.4%, 82/189). Participation led 31.2% (59/189) to seek a second opinion or bring additional information to the attention of their treatment team and 71.9% (136/189) reported plans to increase their outreach and advocacy efforts as a result of participation. Levels of reported anxiety before and after participation were analyzed: 29 of 43 (67%) patients who initially reported "high or extreme" anxiety reported "low or no" anxiety after participation (P<.001). Also, no patients initially reporting low or no anxiety before participation reported an increase to high or extreme anxiety after participation. This study demonstrates that breast cancer patients' perceived knowledge increases and their anxiety decreases by participation in a Twitter social media support group.

Social networking websites have attracted considerable attention as a delivery platform for physical activity interventions. Current evidence highlights a need to enhance user engagement with these interventions to actualize their potential. The purpose of this study was to determine which post type generates the most engagement from participants and whether engagement was related to change in physical activity in an intervention delivered via Facebook. Subgroup analysis of the intervention condition of a randomized controlled trial was conducted. The group moderator posted a new message to the private Facebook group each day of the program. The Facebook posts (n = 118) were categorized into the following types: moderator-initiated running program, multimedia, motivational, opinion polls, or discussion question and participant-initiated experience shares, or questions. Four metrics were used to measure volume of engagement with each post type, "likes," "comments," "poll votes," and "photo uploads." One-way ANOVA was used to determine whether engagement differed by post type and an independent samples t-test to determine differences in engagement between moderator and participant-initiated posts. Pearson correlation was used to examine associations between total engagement and change in physical activity. Engagement varied by post type. Polls elicited the greatest engagement (p ≤ .01). The most common form of engagement was "likes," and engagement was higher for moderator-initiated rather than participant-initiated posts (mean = 8.0 [SD 6.8] vs. 5.3 [SD 3.2]; p ≤ .01). Total engagement with the Facebook group was not directly associated with change in physical activity (r = -.13, p = .47). However, engagement was associated with compliance with the running program (r = .37, p = .04) and there was a nonsignificant positive association between compliance and change in physical activity (r = .32, p = .08). Posts requiring a simple response generated the most

Widely popular, Twitter, a free social networking and micro-blogging service, offers potential for health promotion. This study examined the activity of Twitter quit smoking social network accounts. A cross-sectional analysis identified 153 activated Twitter quit smoking accounts dating back to 2007 and examined recent account activity for the month of August 2010. The accounts had a median of 155 followers and 82 total tweets per account; 49% of accounts had >100 tweets. Posted content was largely inconsistent with clinical guidelines; 48% linked to commercial sites for quitting smoking and 43% had tweets on e-cigarettes. In August 2010, 81 of the accounts (53%) were still active. Though popular for building quit smoking social networks, many of the Twitter accounts were no longer active, and tweet content was largely inconsistent with clinical guidelines. Future research is needed to examine the effectiveness of Twitter for supporting smoking cessation.

Among behavioural addictions, addiction towards social media sites are identified, which are subtypes of compulsive internet usage. Among these, the most significant is the so-called Facebook addiction. Scientific experts agree, that this new phenomenon hasn't been known in detail yet, so it needs intensified scientific exploration. Different aspects of the personality are inclined to raise the probability of developing Facebook addiction. Neurotic and narcissistic traits of the personality are modifying the characteristic of Facebook use, and by this tendency, risk the individual for developing addiction. Our study aimed at measuring Facebook addiction properly, moreover to identifiy the maladaptive characteristics of Facebook use which are salient in the addiction. Our sample consisted of 117 secondary school students. To measure Facebook addiction we used the Hungarian translated version of the Bergen Facebook Addiction Scale. To examine the special neurotic and narcissistic signs of Facebook usage we have developed our own questionniare. We measured neurotic personality traits with the MMPI "Psychasthenia" scale and we measured narcissism with the NPI-16. According to our results, narcissism and neurotic personality traits influence the use of Facebook and the maladaptive usage mediates the addiction.

Background Despite concerns about their health risks, e‑cigarettes have gained popularity in recent years. Concurrent with the recent increase in e‑cigarette use, social media sites such as Twitter have become a common platform for sharing information about e-cigarettes and to promote marketing of e‑cigarettes. Monitoring the trends in e‑cigarette–related social media activity requires timely assessment of the content of posts and the types of users generating the content. However, little is known about the diversity of the types of users responsible for generating e‑cigarette–related content on Twitter. Objective The aim of this study was to demonstrate a novel methodology for automatically classifying Twitter users who tweet about e‑cigarette–related topics into distinct categories. Methods We collected approximately 11.5 million e‑cigarette–related tweets posted between November 2014 and October 2016 and obtained a random sample of Twitter users who tweeted about e‑cigarettes. Trained human coders examined the handles’ profiles and manually categorized each as one of the following user types: individual (n=2168), vaper enthusiast (n=334), informed agency (n=622), marketer (n=752), and spammer (n=1021). Next, the Twitter metadata as well as a sample of tweets for each labeled user were gathered, and features that reflect users’ metadata and tweeting behavior were analyzed. Finally, multiple machine learning algorithms were tested to identify a model with the best performance in classifying user types. Results Using a classification model that included metadata and features associated with tweeting behavior, we were able to predict with relatively high accuracy five different types of Twitter users that tweet about e‑cigarettes (average F1 score=83.3%). Accuracy varied by user type, with F1 scores of individuals, informed agencies, marketers, spammers, and vaper enthusiasts being 91.1%, 84.4%, 81.2%, 79.5%, and 47.1%, respectively
The uses and abuses of Facebook: A review of Facebook addiction
RYAN, TRACII; CHESTER, ANDREA; REECE, JOHN; XENOS, SOPHIA

Abstract Background and aims: Recent research suggests that use of social networking sites can be addictive for some individuals. Due to the link between motivations for media use and the development of addiction, this systematic review examines Facebook-related uses and gratifications research and Facebook addiction research. Method: Searches of three large academic databases revealed 24 studies examining the uses and gratifications of Facebook, and nine studies of Facebook addiction. Results: Comparison of uses and gratifications research reveals that the most popular mo- tives for Facebook use are relationship maintenance, passing time, entertainment, and companionship. These motivations may be related to Facebook addiction through use that is habitual, excessive, or motivated by a desire for mood alteration. Examination of Facebook addiction research indicates that Facebook use can become habitual or excessive, and some addicts use the site to escape from negative moods. However, examination of Facebook addic- tion measures highlights inconsistency in the field. Discussion: There is some evidence to support the argument that uses and gratifications of Facebook are linked with Facebook addiction. Furthermore, it appears as if the social skill model of addiction may explain Facebook addiction, but inconsistency in the measurement of this condition limits the ability to provide conclusive arguments. Conclusions: This paper recommends that further research be performed to establish the links between uses and gratifications and Facebook addiction. Furthermore, in order to enhance the construct validity of Facebook addiction, researchers should take a more systematic approach to assessment. PMID:25317337

There are few studies analysing the influence of personal traits and motivation factors on Facebook usage and Facebook addictive tendency as seen in university students. In this study, 225 Taiwanese university students completed a questionnaire to determine their online psychological privacy scale, Facebook usage motivation scale, Facebook usage scale and Facebook addictive tendency scale, in order to evaluate the items that can be conceptualized as the effect of university students' online psychological privacy personal trait and motive factors, and Facebook usage motivation with respect to Facebook usage and Facebook addictive tendency. The study found that a desire for more online psychological privacy correlates with a stronger motivation to use Facebook and more Facebook usage behaviour among university students who may become high-risk groups for Facebook addictive tendency. The study found that a desire for or an acceptance of a lower online psychological privacy correlates with a stronger motivation to use Facebook among university students who may have more Facebook usage behaviour. This study can help understand university students' Facebook usage and Facebook addictive tendency and provide feature indicators for those who may become high-risk groups for Facebook addictive tendency. Finally, this study conducts discussion and proposes relevant suggestions for future study. Copyright © 2014 John Wiley & Sons, Ltd.

Vaccine Images on Twitter: Analysis of What Images are Shared
Dredze, Mark
2018-01-01
Background Visual imagery plays a key role in health communication; however, there is little understanding of what aspects of vaccine-related images make them effective communication aids. Twitter, a popular venue for discussions related to vaccination, provides numerous images that are shared with tweets. Objective The objectives of this study were to understand how images are used in vaccine-related tweets and provide guidance with respect to the characteristics of vaccine-related images that correlate with the higher likelihood of being retweeted. Methods We collected more than one million vaccine image messages from Twitter and characterized various properties of these images using automated image analytics. We fit a logistic regression model to predict whether or not a vaccine image tweet was retweeted, thus identifying characteristics that correlate with a higher likelihood of being shared. For comparison, we built similar models for the sharing of vaccine news on Facebook and for general image tweets. Results Most vaccine-related images are duplicates (125,916/237,478; 53.02%) or taken from other sources, not necessarily created by the author of the tweet. Almost half of the images contain embedded text, and many include images of people and syringes. The visual content is highly correlated with a tweet’s textual topics. Vaccine image tweets are twice as likely to be shared as nonimage tweets. The sentiment of an image and the objects shown in the image were the predictive factors in determining whether an image was retweeted. Conclusions We are the first to study vaccine images on Twitter. Our findings suggest future directions for the study and use of vaccine imagery and may inform communication strategies around vaccination. Furthermore, our study demonstrates an effective study methodology for image analysis. PMID:29615386

The Facebook Experiment: Quitting Facebook Leads to Higher Levels of Well-Being.
Tromholt, Morten
2016-11-01
Most people use Facebook on a daily basis; few are aware of the consequences. Based on a 1-week experiment with 1,095 participants in late 2015 in Denmark, this study provides causal evidence that Facebook use affects our well-being negatively. By comparing the treatment group (participants who took a break from Facebook) with the control group (participants who kept using Facebook), it was demonstrated that taking a break from Facebook has positive effects on the two dimensions of well-being: our life satisfaction increases and our emotions become more positive. Furthermore, it was demonstrated that these effects were significantly greater for heavy Facebook users, passive Facebook users, and users who tend to envy others on Facebook.

Medical journals use social media as a means to disseminate new research and interact with readers. The microblogging site Twitter is one such platform. The aim of this study was to analyze the recent use of Twitter by the leading radiology journals. The top 50 journals by Impact Factor were included. Twitter profiles associated with these journals, or their corresponding societies, were identified. Whether each journal used other social media platforms was also recorded. Each Twitter profile was analyzed over a one-year period, with data collected via Twitonomy software. Klout scores of social media influence were calculated. Results were analyzed in SPSS using Student's t test, Fisher contingency tables, and Pearson correlations to identify any association between social media interaction and Impact Factors of journals. Fourteen journals (28%) had dedicated Twitter profiles. Of the 36 journals without dedicated Twitter profiles, 25 (50%) were associated with societies that had profiles, leaving 11 (22%) journals without a presence on Twitter. The mean Impact Factor of all journals was 3.1 ± 1.41 (range, 1.7-6.9). Journals with Twitter profiles had higher Impact Factors than those without (mean, 3.37 vs 2.14; P < .001). There was no statistically significant difference between the Impact Factors of the journals with dedicated Twitter profiles and those associated with affiliated societies (P = .47). Since joining Twitter, 7 of the 11 journals (64%) experienced increases in Impact Factor. A greater number of Twitter followers was correlated with higher journal Impact Factor (R 2 = 0.581, P = .029). The investigators assessed the prevalence and activity of the leading radiology journals on Twitter. Radiology journals with Twitter profiles have higher Impact Factors than those without profiles, and the number of followers of a journal's Twitter profile is positively associated with Impact Factor.

The use of social media by dermatology journals and professional and patient-centered dermatology organizations remains largely unknown and, to our knowledge, has yet to be fully evaluated. To evaluate and quantify the extent of involvement of dermatology journals, professional dermatology organizations, and dermatology-related patient advocate groups on social networking sites. We obtained an archived list of 102 current dermatology journals from SCImago on the World Wide Web and used the list to investigate Facebook, Twitter, and individual journal websites for the presence of social media accounts. We identified professional and patient-centered dermatology organization activity on social networks through queries of predetermined search terms on Google, Facebook, Twitter, and LinkedIn. The activity of each entity was documented by recording the following metrics of popularity: the numbers of Facebook "likes," Twitter "followers," and LinkedIn "members." The numbers of Facebook likes, Twitter followers, and LinkedIn members corresponding to each dermatology journal and each professional and patient-related dermatology organization. On July 17, 2012, of the 102 dermatology journals ranked by SCImago, 12.7% were present on Facebook and 13.7% on Twitter. We identified popular dermatology journals based on Facebook likes and Twitter followers, led by the Journal of the American Academy of Dermatology and Dermatology Times, respectively. Popular professional dermatology organizations included dermRounds Dermatology Network (11 251 likes on Facebook and 2900 followers on Twitter). The most popular dermatology patient-centered organizations were the Skin Cancer Foundation (20 119 likes on Facebook), DermaTalk (21 542 followers on Twitter), and the National Psoriasis Foundation (200 members on LinkedIn). Patient-centered and professional dermatology organizations use social networking sites; however, academic journals tend to lag behind significantly. Although some
Social Medicine: Twitter in Healthcare.

Social media enables the public sharing of information. With the recent emphasis on transparency and the open sharing of information between doctors and patients, the intersection of social media and healthcare is of particular interest. Twitter is currently the most popular form of social media used for healthcare communication; here, we examine the use of Twitter in medicine and specifically explore in what capacity using Twitter to share information on treatments and research has the potential to improve care. The sharing of information on Twitter can create a communicative and collaborative atmosphere for patients, physicians, and researchers and even improve quality of care. However, risks involved with using Twitter for healthcare discourse include high rates of misinformation, difficulties in verifying the credibility of sources, overwhelmingly high volumes of information available on Twitter, concerns about professionalism, and the opportunity cost of using physician time. Ultimately, the use of Twitter in healthcare can allow patients, healthcare professionals, and researchers to be more informed, but specific guidelines for appropriate use are necessary.

Diabetes topics associated with engagement on Twitter.
Harris, Jenine K; Mart, Adelina; Moreland-Russell, Sarah; Caburnay, Charlene A
2015-05-07
Social media are widely used by the general public and by public health and health care professionals. Emerging evidence suggests engagement with public health information on social media may influence health behavior. However, the volume of data accumulating daily on Twitter and other social media is a challenge for researchers with limited resources to further examine how social media influence health. To address this challenge, we used crowdsourcing to facilitate the examination of topics associated with engagement with diabetes information on Twitter. We took a random sample of 100 tweets that included the hashtag "#diabetes" from each day during a constructed week in May and June 2014. Crowdsourcing through Amazon's Mechanical Turk platform was used to classify tweets into 9 topic categories and their senders into 3 Twitter user categories. Descriptive statistics and Tweedie regression were used to identify tweet and Twitter user characteristics associated with 2 measures of engagement, "favoriting" and "retweeting." Classification was reliable for tweet topics and Twitter user type. The most common tweet topics were medical and nonmedical resources for diabetes. Tweets that included information about diabetes-related health problems were positively and significantly associated with engagement. Tweets about diabetes prevalence, nonmedical resources for diabetes, and jokes or sarcasm about diabetes were significantly negatively associated with engagement. Crowdsourcing is a reliable, quick, and economical option for classifying tweets. Public health practitioners aiming to engage constituents around diabetes may want to focus on topics positively associated with engagement.

As Twitter has grown in popularity to 313 million monthly active users, researchers have increasingly been using it as a data source for tobacco-related research. The objective of this systematic review was to assess the methodological approaches of categorically coded tobacco Twitter data and make recommendations for future studies. Data sources included PsycINFO, Web of Science, PubMed, ABI/INFORM, Communication Source, and Tobacco Regulatory Science. Searches were limited to peer-reviewed journals and conference proceedings in English from January 2006 to July 2016. The initial search identified 274 articles using a Twitter keyword and a tobacco keyword. One coder reviewed all abstracts and identified 27 articles that met the following inclusion criteria: (1) original research, (2) focused on tobacco or a tobacco product, (3) analyzed Twitter data, and (4) coded Twitter data categorically. One coder extracted data collection and coding methods. E-cigarettes were the most common type of Twitter data analyzed, followed by specific tobacco campaigns. The most prevalent data sources were Gnip and Twitter's Streaming application programming interface (API). The primary methods of coding were hand-coding and machine learning. The studies predominantly coded for relevance, sentiment, theme, user or account, and location of user. Standards for data collection and coding should be developed to be able to more easily compare and replicate tobacco-related Twitter results. Additional recommendations include the following: sample Twitter's databases multiple times, make a distinction between message attitude and emotional tone for sentiment, code images and URLs, and analyze user profiles. Being relatively novel and widely used among adolescents and black and Hispanic individuals, Twitter could provide a rich source of tobacco surveillance data among vulnerable populations. ©Brianna A Lienemann, Jennifer B Unger, Tess Boley Cruz, Kar-Hai Chu.

Twitter chatter about marijuana.
Cavazos-Rehg, Patricia A; Krauss, Melissa; Fisher, Sherri L; Salyer, Patricia; Grucza, Richard A; Bierut, Laura Jean
2015-02-01
We sought to examine the sentiment and themes of marijuana-related chatter on Twitter sent by influential Twitter users and to describe the demographics of these Twitter users. We assessed the sentiment and themes of a random sample (n = 7,000) of influential marijuana-related tweets (sent from February 5, 20114, to March 5, 2014). Demographics of the users tweeting about marijuana were inferred using a social media analytics company (Demographics Pro for Twitter). Most marijuana-related tweets reflected a positive sentiment toward marijuana use, with pro-marijuana tweets outnumbering anti-marijuana tweets by a factor of greater than 15. The most common theme of pro-marijuana tweets included the Tweeter stating that he/she wants/plans to use marijuana, followed by tweeting about frequent/heavy/or regular marijuana use, and that marijuana has health benefits and/or should be legalized. Tweeters of marijuana-related content were younger and a greater proportion was African-American compared with the Twitter average. Marijuana Twitter chatter sent by influential Twitter users tends to be pro-marijuana and popular among African-Americans and youth/young adults. Marijuana-related harms may afflict some individuals; therefore, our findings should be used to inform online and offline prevention efforts that work to target individuals who are most at risk for harms associated with marijuana use.

2016-02-01
Facebook has been used in health research, but there is a lack of literature regarding how Facebook may be used to recruit younger adolescents. A Facebook Page was created for an adolescent cohort study on the effects of puberty hormones on well-being and behaviour in early adolescence. Used as a communication tool with existing participants, it also aimed to alert potential participants to the study. The purpose of this paper is to provide a detailed description of the development of the study Facebook Page and present the fan response to the types of posts made on the Page using the Facebook-generated Insights data. Two types of posts were made on the study Facebook Page. The first type was study-related update posts and events. The second was relevant adolescent and family research and current news posts. Observations on the use of and response to the Page were made over 1 year across three phases (phase 1, very low Facebook use; phase 2, high Facebook use; phase 3, low Facebook use). Most Page fans were female (88.6%), with the largest group of fans aged between 35 and 44 years. Study-related update posts with photographs were the most popular. This paper provides a model on which other researchers could base Facebook communication and potential recruitment in the absence of established guidelines.

Using Twitter to Measure Public Discussion of Diseases: A Case Study
Schwartz, H Andrew; Hill, Shawndra; Merchant, Raina M; Arango, Catalina; Ungar, Lyle
2015-01-01
Background Twitter is increasingly used to estimate disease prevalence, but such measurements can be biased, due to both biased sampling and inherent ambiguity of natural language. Objective We characterized the extent of these biases and how they vary with disease. Methods We correlated self-reported prevalence rates for 22 diseases from Experian’s Simmons National Consumer Study (n=12,305) with the number of times these diseases were mentioned on Twitter during the same period (2012). We also identified and corrected for two types of bias present in Twitter data: (1) demographic variance between US Twitter users and the general US population; and (2) natural language ambiguity, which creates the possibility that mention of a disease name may not actually refer to the disease (eg, “heart attack” on Twitter often does not refer to myocardial infarction). We measured the correlation between disease prevalence and Twitter disease mentions both with and without bias correction. This allowed us to quantify each disease’s overrepresentation or underrepresentation on Twitter, relative to its prevalence. Results Our sample included 80,680,449 tweets. Adjusting disease prevalence to correct for Twitter demographics more than doubles the correlation between Twitter disease mentions and disease prevalence in the general population (from .113 to .258, P <.001). In addition, diseases varied widely in how often mentions of their names on Twitter actually referred to the diseases, from 14.89% (3827/25,704) of instances (for stroke) to 99.92% (5044/5048) of instances (for arthritis). Applying ambiguity correction to our Twitter corpus achieves a correlation between disease mentions and prevalence of .208 ( P <.001). Simultaneously applying correction for both demographics and ambiguity more than triples the baseline correlation to .366 ( P <.001). Compared with prevalence rates, cancer appeared most overrepresented in Twitter, whereas high cholesterol appeared most

Twitter for travel medicine providers.
Mills, Deborah J; Kohl, Sarah E
2016-03-01
Travel medicine practitioners, perhaps more so than medical practitioners working in other areas of medicine, require a constant flow of information to stay up-to-date, and provide best practice information and care to their patients. Many travel medicine providers are unaware of the popularity and potential of the Twitter platform. Twitter use among our travellers, as well as by physicians and health providers, is growing exponentially. There is a rapidly expanding body of published literature on this information tool. This review provides a brief overview of the ways Twitter is being used by health practitioners, the advantages that are peculiar to Twitter as a platform of social media, and how the interested practitioner can get started. Some key points about the dark side of Twitter are highlighted, as well as the potential benefits of using Twitter as a way to disseminate accurate medical information to the public. This article will help readers develop an increased understanding of Twitter as a tool for extracting useful facts and insights from the ever increasing volume of health information. © International Society of Travel Medicine, 2016.

Background Since their inception, Twitter and related microblogging systems have provided a rich source of information for researchers and have attracted interest in their affordances and use. Since 2009 PubMed has included 123 journal articles on medicine and Twitter, but no overview exists as to how the field uses Twitter in research. Objective This paper aims to identify published work relating to Twitter within the fields indexed by PubMed, and then to classify it. This classification will provide a framework in which future researchers will be able to position their work, and to provide an understanding of the current reach of research using Twitter in medical disciplines. Methods Papers on Twitter and related topics were identified and reviewed. The papers were then qualitatively classified based on the paper’s title and abstract to determine their focus. The work that was Twitter focused was studied in detail to determine what data, if any, it was based on, and from this a categorization of the data set size used in the studies was developed. Using open coded content analysis additional important categories were also identified, relating to the primary methodology, domain, and aspect. Results As of 2012, PubMed comprises more than 21 million citations from biomedical literature, and from these a corpus of 134 potentially Twitter related papers were identified, eleven of which were subsequently found not to be relevant. There were no papers prior to 2009 relating to microblogging, a term first used in 2006. Of the remaining 123 papers which mentioned Twitter, thirty were focused on Twitter (the others referring to it tangentially). The early Twitter focused papers introduced the topic and highlighted the potential, not carrying out any form of data analysis. The majority of published papers used analytic techniques to sort through thousands, if not millions, of individual tweets, often depending on automated tools to do so. Our analysis demonstrates that

The majority of published papers used analytic techniques to sort through thousands, if not millions, of individual tweets, often depending on automated tools to do so. Our analysis demonstrates that researchers are starting to use knowledge

For many people, the word "twitter" brings to mind birds rather than humans. But information professionals know that Twitter (www.twitter.com) is a fast-growing, free messaging service for people, and it's one that libraries (and librarians) can make good use of--without spending much time or effort.

Vape, quit, tweet? Electronic cigarettes and smoking cessation on Twitter.
van der Tempel, Jan; Noormohamed, Aliya; Schwartz, Robert; Norman, Cameron; Malas, Muhannad; Zawertailo, Laurie
2016-03-01
Individuals seeking information about electronic cigarettes are increasingly turning to social media networks like Twitter. We surveyed dominant Twitter communications about e-cigarettes and smoking cessation, examining message sources, themes, and attitudes. Tweets from 2014 were searched for mentions of e-cigarettes and smoking cessation. A purposive sample was subjected to mixed-methods analysis. Twitter communication about e-cigarettes increased fivefold since 2012. In a sample of 300 tweets from high-authority users, attitudes about e-cigarettes as smoking cessation aids were favorable across user types (industry, press, public figures, fake accounts, and personal users), except for public health professionals, who lacked consensus and contributed negligibly to the conversation. The most prevalent message themes were marketing, news, and first-person experiences with e-cigarettes as smoking cessation aids. We identified several industry strategies to reach Twitter users. Our findings show that Twitter users are overwhelmingly exposed to messages that favor e-cigarettes as smoking cessation aids, even when disregarding commercial activity. This underlines the need for effective public health engagement with social media to provide reliable information about e-cigarettes and smoking cessation online.

Aim Social media (SoMe) platforms have become leading methods of communication and dissemination of scientific information in the medical community. They allow for immediate discussion and widespread engagement around important topics. It has been hypothesized that the activity on Twitter positively correlates with highly cited articles. The purpose of this study was to analyze the prevalence and activity of Trauma and Orthopaedic Surgery journals on Twitter, with the hypothesis that impact factor is positively associated with Twitter usage. Methods The top 50 Trauma and Orthopaedic Surgery journals, ranked by 2016 Impact Factor were analyzed. The Twitter profiles of each journal or affiliated society were identified. Other SoMe platforms used were also recorded. Twitonomy software (Digonomy Pty Ltd, New South Wales, Australia) was used to analyze the Twitter profiles over a one-year period. Twitter Klout Scores were recorded for each journal to approximate the SoMe influence. Altmetric Scores (the total number of mentions via alternative metrics) were also recorded. Statistical analysis was carried out to identify correlations between journal Impact Factors, SoMe activity, Twitter Klout Scores and Altmetric Scores. Results Twenty-two journals (44%) had dedicated Twitter profiles. Fourteen journals (28%) were associated with societies that had profiles and 14 journals (28%) had no Twitter presence. The mean Impact Factor overall was 2.16 +/- 0.14 (range, 1.07-5.16). The journals with dedicated Twitter profiles had higher Impact Factors than those without (mean 2.41 vs. 1.61; P=0.005). A greater number of Twitter followers were associated with higher Impact Factors (R2 0.317, P=0.03). Journals with higher Twitter Klout Scores had higher Impact Factors (R2 0.357, P=0.016). Altmetric Score was positively associated with Impact Factor (R2 0.310, P=0.015). Journals with higher numbers of retweets (virtual citations in the Twittersphere) had higher Altmetric Scores

Kite, James; Foley, Bridget C; Grunseit, Anne C; Freeman, Becky
2016-01-01
Facebook, the most widely used social media platform, has been adopted by public health organisations for health promotion and behaviour change campaigns and activities. However, limited information is available on the most effective and efficient use of Facebook for this purpose. This study sought to identify the features of Facebook posts that are associated with higher user engagement on Australian public health organisations' Facebook pages. We selected 20 eligible pages through a systematic search and coded 360-days of posts for each page. Posts were coded by: post type (e.g., photo, text only etc.), communication technique employed (e.g. testimonial, informative etc.) and use of marketing elements (e.g., branding, use of mascots). A series of negative binomial regressions were used to assess associations between post characteristics and user engagement as measured by the number of likes, shares and comments. Our results showed that video posts attracted the greatest amount of user engagement, although an analysis of a subset of the data suggested this may be a reflection of the Facebook algorithm, which governs what is and is not shown in user newsfeeds and appear to preference videos over other post types. Posts that featured a positive emotional appeal or provided factual information attracted higher levels of user engagement, while conventional marketing elements, such as sponsorships and the use of persons of authority, generally discouraged user engagement, with the exception of posts that included a celebrity or sportsperson. Our results give insight into post content that maximises user engagement and begins to fill the knowledge gap on effective use of Facebook by public health organisations.

The use of social networking sites is increasingly being adopted in public health, in part, because of the barriers to funding and reduced resources. Public health professionals are using social media platforms, specifically Twitter, as a way to facilitate professional development. The objective of this study was to identify public health professionals using Twitter and to analyze how they use this platform to enhance their formal and informal professional development within the context of public health. Keyword searches were conducted to identify and invite potential participants to complete a survey related to their use of Twitter for public health and professional experiences. Data regarding demographic attributes, Twitter usage, and qualitative information were obtained through an anonymous Web-based survey. Open-response survey questions were analyzed using the constant comparison method. "Using Twitter makes it easier to expand my networking opportunities" and "I find Twitter useful for professional development" scored highest, with a mean score of 4.57 (standard deviation [SD] 0.74) and 4.43 (SD 0.76) on a 5-point Likert scale. Analysis of the qualitative data shows the emergence of the following themes for why public health professionals mostly use Twitter: (1) geography, (2) continuing education, (3) professional gain, and (4) communication. For public health professionals in this study, Twitter is a platform best used for their networking and professional development. Furthermore, the use of Twitter allows public health professionals to overcome a series of barriers and enhances opportunities for growth. ©Mark Hart, Nichole E Stetten, Sabrina Islam, Katherine Pizarro.

Methods for Coding Tobacco-Related Twitter Data: A Systematic Review
Unger, Jennifer B; Cruz, Tess Boley; Chu, Kar-Hai
2017-01-01
Background As Twitter has grown in popularity to 313 million monthly active users, researchers have increasingly been using it as a data source for tobacco-related research. Objective The objective of this systematic review was to assess the methodological approaches of categorically coded tobacco Twitter data and make recommendations for future studies. Methods Data sources included PsycINFO, Web of Science, PubMed, ABI/INFORM, Communication Source, and Tobacco Regulatory Science. Searches were limited to peer-reviewed journals and conference proceedings in English from January 2006 to July 2016. The initial search identified 274 articles using a Twitter keyword and a tobacco keyword. One coder reviewed all abstracts and identified 27 articles that met the following inclusion criteria: (1) original research, (2) focused on tobacco or a tobacco product, (3) analyzed Twitter data, and (4) coded Twitter data categorically. One coder extracted data collection and coding methods. Results E-cigarettes were the most common type of Twitter data analyzed, followed by specific tobacco campaigns. The most prevalent data sources were Gnip and Twitter’s Streaming application programming interface (API). The primary methods of coding were hand-coding and machine learning. The studies predominantly coded for relevance, sentiment, theme, user or account, and location of user. Conclusions Standards for data collection and coding should be developed to be able to more easily compare and replicate tobacco-related Twitter results. Additional recommendations include the following: sample Twitter’s databases multiple times, make a distinction between message attitude and emotional tone for sentiment, code images and URLs, and analyze user profiles. Being relatively novel and widely used among adolescents and black and Hispanic individuals, Twitter could provide a rich source of tobacco surveillance data among vulnerable populations.

Using Twitter to communicate conservation science from a professional conference.
Bombaci, Sara P; Farr, Cooper M; Gallo, H Travis; Mangan, Anna M; Stinson, Lani T; Kaushik, Monica; Pejchar, Liba
2016-02-01
Scientists are increasingly using Twitter as a tool for communicating science. Twitter can promote scholarly discussion, disseminate research rapidly, and extend and diversify the scope of audiences reached. However, scientists also caution that if Twitter does not accurately convey science due to the inherent brevity of this media, misinformation could cascade quickly through social media. Data on whether Twitter effectively communicates conservation science and the types of user groups receiving these tweets are lacking. To address these knowledge gaps, we examined live tweeting as a means of communicating conservation science at the 2013 International Congress for Conservation Biology (ICCB). We quantified and compared the user groups sending and reading live tweets. We also surveyed presenters to determine their intended audiences, which we compared with the actual audiences reached through live tweeting. We also asked presenters how effectively tweets conveyed their research findings. Twitter reached 14 more professional audience categories relative to those attending and live tweeting at ICCB. However, the groups often reached through live tweeting were not the presenters' intended audiences. Policy makers and government and non-governmental organizations were rarely reached (0%, 4%, and 6% of audience, respectively), despite the intent of the presenters. Plenary talks were tweeted about 6.9 times more than all other oral or poster presentations combined. Over half the presenters believed the tweets about their talks were effective. Ineffective tweets were perceived as vague or missing the presenters' main message. We recommend that presenters who want their science to be communicated accurately and broadly through Twitter should provide Twitter-friendly summaries that incorporate relevant hashtags and usernames. Our results suggest that Twitter can be used to effectively communicate speakers' findings to diverse audiences beyond conference walls. © 2015

While plenty of research has provided important insights into the uses of the Internet by politicians during elections, a relatively scarce amount of work has looked into these uses outside of such parliamentary events. This article seeks to remedy this lack of research by presenting a study on the 'routine' uses of two of the currently most popular social media services - Facebook and Twitter. Focusing on politicians elected to the national parliaments of Norway and Sweden, the article employs novel methodologies for data collection and statistical analyses in order to provide an overarching, structural view of the day-to-day social media practices of Scandinavian politicians. Findings indicate that use levels are rather low for both services - the median amount of tweets sent and messages posted on Facebook is close to one per day. Further analyses reveal that the most active politicians could be labelled as 'underdogs', as they are more likely to be younger, in opposition and out of the political limelight.
Introducing the Twitter Impact Factor: An Objective Measure of Urology's Academic Impact on Twitter.
Cardona-Grau, Diana; Sorokin, Igor; Leinwand, Gabriel; Welliver, Charles
2016-10-01
Social media use in academia and urology is rising. Specifically, individual journals now have Twitter accounts (Twitter Inc, San Francisco, CA, USA) and regularly tweet academic content. To present and evaluate the Twitter impact factor (TIF), a novel means of measuring a journal's academic influence in the realm of social media. Journal Citation Reports (JCR; Thomson Reuters, New York, NY, USA) for 2014 was queried for urologic academic journals. English-language journals with active Twitter accounts since 2013 were included. The total number of followers, tweets, and retweets over a 2-yr period were collected. Each journal's TIF was calculated based on the number of retweets per original relevant tweet. Comparisons between the TIF and the journal impact factor (JIF) as well as the Klout score were made using the Pearson correlation. Of 33 journals listed in the JCR for 2014, 7 (21%) had a Twitter presence as of 2013. The number of JCR-listed journals with a Twitter handle increased by 29% in 2014. There was an increase in the mean number of relevant tweets per journal during the study period and a 130% increase in the number of retweets over 1 yr. European Urology (1.80) and BJU International (1.46) had the highest TIFs. The journals with the highest number of Twitter followers were European Urology (5807) and the Journal of Urology (4402). The journals with the highest numbers of relevant tweets were European Urology (1159) and BJU International (1090). There was a positive but statistically insignificant association between the TIF and the JIF (r=0.64, p=0.12). There was a strongly positive linear correlation between the TIF and the Klout score (r=0.84, p=0.0086). With the increasing use of social media by individuals and academic journals, the TIF can be a useful tool to measure the academic reach and impact of a journal on Twitter. Social media is an increasing part of the way in which practitioners and academicians communicate. The TIF can be used to
Facebook Groups for the Management of Chronic Diseases.
Partridge, Stephanie R; Gallagher, Patrick; Freeman, Becky; Gallagher, Robyn
2018-01-17
The use of Facebook groups by health care researchers and professionals for chronic disease management, namely type 2 diabetes mellitus and coronary heart disease, is in its early stages and challenges are emerging. While Facebook groups offer great potential to deliver health support, research of Facebook groups for chronic disease management remains in its infancy, with robust evidence not yet available. Designing Facebook groups that are acceptable to users, health care researchers as well as health care professionals is a challenge, and there is a poor fit with traditional research and evaluation methods. Key recommendations for future research of Facebook groups for chronic disease management include: (1) iterative content development with input from the target patient population; (2) further understanding of the potential role of group "champions"; (3) ensuring the social media policies of health care institutions allow for real time online communication; and (4) utilizing comprehensive evaluation strategies, including the use of process evaluations. ©Stephanie R Partridge, Patrick Gallagher, Becky Freeman, Robyn Gallagher.

In this study we present and empirically examine a new phenomenon related to social networking sites, such as Facebook, the "false Facebook-self." Arguably false self-presentation on Facebook is a growing phenomenon, and in extreme cases; i.e., when ones Facebook image substantially deviates from their true image, it may serve as a gateway behavior to more problematic behaviors which may lead to psychological problems and even pathologies. In this study we show that certain users are more vulnerable to such false self-presentation than others. The study involved 258 Facebook users. Applying ANOVA and SEM analyses we show that users with low self-esteem and low trait authenticity are more likely than others to present a Facebook-self which deviates from their true selves. These social-interaction-related traits are influenced by one's upbringing and the anxious and avoidant attachment styles he or she has developed. Several cases (7.5%) with large gaps between the true and false Facebook-self were detected, which implies that future research should consider the adverse consequences and treatments of high levels of false Facebook-self.
Health organizations providing and seeking social support: a Twitter-based content analysis.
Rui, Jian Raymond; Chen, Yixin; Damiano, Amanda
2013-09-01
Providing and seeking social support are important aspects of social exchange. New communication technologies, especially social network sites (SNSs), facilitate the process of support exchange. An increasing number of health organizations are using SNSs. However, how they provide and seek social support via SNSs has yet to garner academic attention. This study examined the types of social support provided and sought by health organizations on Twitter. A content analysis was conducted on 1,500 tweets sent by a random sample of 58 health organizations within 2 months. Findings indicate that providing informational and emotional support, as well as seeking instrumental support, were the main types of social support exchanged by health organizations through Twitter. This study provides a typology for studying social support exchanges by health organizations, and recommends strategies for health organizations regarding the effective use of Twitter.

Background Twitter provides various types of location data, including exact Global Positioning System (GPS) coordinates, which could be used for infoveillance and infodemiology (ie, the study and monitoring of online health information), health communication, and interventions. Despite its potential, Twitter location information is not well understood or well documented, limiting its public health utility. Objective The objective of this study was to document and describe the various types of location information available in Twitter. The different types of location data that can be ascertained from Twitter users are described. This information is key to informing future research on the availability, usability, and limitations of such location data. Methods Location data was gathered directly from Twitter using its application programming interface (API). The maximum tweets allowed by Twitter were gathered (1% of the total tweets) over 2 separate weeks in October and November 2011. The final dataset consisted of 23.8 million tweets from 9.5 million unique users. Frequencies for each of the location options were calculated to determine the prevalence of the various location data options by region of the world, time zone, and state within the United States. Data from the US Census Bureau were also compiled to determine population proportions in each state, and Pearson correlation coefficients were used to compare each state’s population with the number of Twitter users who enable the GPS location option. Results The GPS location data could be ascertained for 2.02% of tweets and 2.70% of unique users. Using a simple text-matching approach, 17.13% of user profiles in the 4 continental US time zones were able to be used to determine the user’s city and state. Agreement between GPS data and data from the text-matching approach was high (87.69%). Furthermore, there was a significant correlation between the number of Twitter users per state and the 2010 US Census state

Analysis of emergency physicians' Twitter accounts.
Lulic, Ileana; Kovic, Ivor
2013-05-01
Twitter is one of the fastest growing social media networks for communication between users via short messages. Technology proficient physicians have demonstrated enthusiasm in adopting social media for their work. To identify and create the largest directory of emergency physicians on Twitter, analyse their user accounts and reveal details behind their connections. Several web search tools were used to identify emergency physicians on Twitter with biographies completely or partially written in English. NodeXL software was used to calculate emergency physicians' Twitter network metrics and create visualisation graphs. The authors found 672 Twitter accounts of self-identified emergency physicians. Protected accounts were excluded from the study, leaving 632 for further analysis. Most emergency physicians were located in USA (55.4%), had created their accounts in 2009 (43.4%), used their full personal name (77.5%) and provided a custom profile picture (92.2%). Based on at least one published tweet in the last 15 days, there were 345 (54.6%) active users on 31 December 2011. Active users mostly used mobile devices based on the Apple operating system to publish tweets (69.2%). Visualisation of emergency physicians' Twitter network revealed many users with no connections with their colleagues, and a small group of most influential users who were highly interconnected. Only a small proportion of registered emergency physicians use Twitter. Among them exists a smaller inner network of emergency physicians with strong social bonds that is using Twitter's full potentials for professional development.

Do altmetrics work? Twitter and ten other social web services.
Thelwall, Mike; Haustein, Stefanie; Larivière, Vincent; Sugimoto, Cassidy R
2013-01-01
Altmetric measurements derived from the social web are increasingly advocated and used as early indicators of article impact and usefulness. Nevertheless, there is a lack of systematic scientific evidence that altmetrics are valid proxies of either impact or utility although a few case studies have reported medium correlations between specific altmetrics and citation rates for individual journals or fields. To fill this gap, this study compares 11 altmetrics with Web of Science citations for 76 to 208,739 PubMed articles with at least one altmetric mention in each case and up to 1,891 journals per metric. It also introduces a simple sign test to overcome biases caused by different citation and usage windows. Statistically significant associations were found between higher metric scores and higher citations for articles with positive altmetric scores in all cases with sufficient evidence (Twitter, Facebook wall posts, research highlights, blogs, mainstream media and forums) except perhaps for Google+ posts. Evidence was insufficient for LinkedIn, Pinterest, question and answer sites, and Reddit, and no conclusions should be drawn about articles with zero altmetric scores or the strength of any correlation between altmetrics and citations. Nevertheless, comparisons between citations and metric values for articles published at different times, even within the same year, can remove or reverse this association and so publishers and scientometricians should consider the effect of time when using altmetrics to rank articles. Finally, the coverage of all the altmetrics except for Twitter seems to be low and so it is not clear if they are prevalent enough to be useful in practice.

Nevertheless, there is a lack of systematic scientific evidence that altmetrics are valid proxies of either impact or utility although a few case studies have reported medium correlations between specific altmetrics and citation rates for individual journals or fields. To fill this gap, this study compares 11 altmetrics with Web of Science citations for 76 to 208,739 PubMed articles with at least one altmetric mention in each case and up to 1,891 journals per metric. It also introduces a simple sign test to overcome biases caused by different citation and usage windows. Statistically significant associations were found between higher metric scores and higher citations for articles with positive altmetric scores in all cases with sufficient evidence (Twitter, Facebook wall posts, research highlights, blogs, mainstream media and forums) except perhaps for Google+ posts. Evidence was insufficient for LinkedIn, Pinterest, question and answer sites, and Reddit, and no conclusions should be drawn about articles with zero altmetric scores or the strength of any correlation between altmetrics and citations. Nevertheless, comparisons between citations and metric values for articles published at different times, even within the same year, can remove or reverse this association and so publishers and scientometricians should consider the effect of time when using altmetrics to rank articles. Finally, the coverage of all the altmetrics except for Twitter seems to be low and so it is not clear if they are prevalent enough to be useful in practice. PMID:23724101
Exploring Hospitals’ Use of Facebook: Thematic Analysis
Young, Diana K
2018-01-01
Background Although health care organizations such as hospitals and clinics have widely embraced social media as a means to educate the community on health topics and increase patient loyalty and satisfaction, little is known about the content these organizations actually share when using social media channels. Objective This study aimed to explore the types of content US hospitals post on their Facebook pages and how hospitals’ Facebook activities differ with regard to content types. Methods We collected and thematically analyzed more than 1700 Facebook posts made over a 3-month period by 17 US hospitals. During the first phase, the 2 researchers coded a set of 159 posts and created an initial thematic web of content. During the second phase, the researchers coded the remaining posts and then revised, refined, and validated the initial web of content accordingly. Coding consensus was achieved on 1184 of the 1548 analyzable sampled posts (76.49%). Results We identified a list of 13 unique health social media post themes and classified those themes into 3 thematic groups that included announcing, sharing, and recognizing activities. The most frequently used theme was sharing health information, which appeared in 35.81% (424/1184) of the posts analyzed. Such posts sought to provide health tips and advice to community members. Recognizing special days and recognizing employees were the second and third most frequently used themes, respectively, with 14.95% (177/1184) and 11.82% (140/1184) of the posts containing those themes. The frequency of these themes was surprising as the content was geared more toward stakeholders internal to the organization, although most previous literature has focused on social media as a tool to connect with external stakeholders. In addition, we found many of the posts involved more than one theme, and selected sets of themes co-occurred frequently. For example, 25.4% (45/177) of the posts recognizing special days also included content

Facebook Addiction: Onset Predictors.
Biolcati, Roberta; Mancini, Giacomo; Pupi, Virginia; Mugheddu, Valeria
2018-05-23
Worldwide, Facebook is becoming increasingly widespread as a communication platform. Young people especially use this social networking site daily to maintain and establish relationships. Despite the Facebook expansion in the last few years and the widespread acceptance of this social network, research into Facebook Addiction (FA) is still in its infancy. Hence, the potential predictors of Facebook overuse represent an important matter for investigation. This study aimed to deepen the understanding of the relationship between personality traits, social and emotional loneliness, life satisfaction, and Facebook addiction. A total of 755 participants (80.3% female; n = 606) aged between 18 and 40 (mean = 25.17; SD = 4.18) completed the questionnaire packet including the Bergen Facebook Addiction Scale, the Big Five, the short version of Social and Emotional Loneliness Scale for Adults, and the Satisfaction with Life Scale. A regression analysis was used with personality traits, social, family, romantic loneliness, and life satisfaction as independent variables to explain variance in Facebook addiction. The findings showed that Conscientiousness, Extraversion, Neuroticism, and Loneliness (Social, Family, and Romantic) were strong significant predictors of FA. Age, Openness, Agreeableness, and Life Satisfaction, although FA-related variables, were not significant in predicting Facebook overuse. The risk profile of this peculiar behavioral addiction is also discussed.
Sharing sensitive personal health information through Facebook: the unintended consequences.
Househ, Mowafa
2011-01-01
The purpose of this paper was to explore the types of sensitive health information posted by individuals through social network media sites such as Facebook. The researcher found several instances in which individuals, who could be identified by their user profiles, posted personal and sensitive health information related to mental and genetic disorders and sexually transmitted diseases. The data suggest that Facebook users should be made aware of the potential harm that may occur when sharing sensitive health information publicly through Facebook. Ethical considerations in undertaking such research are also examined.
Professors' Facebook content affects students' perceptions and expectations.
Sleigh, Merry J; Smith, Aimee W; Laboe, Jason
2013-07-01
Abstract Facebook users must make choices about level of self-disclosure, and this self-disclosure can influence perceptions of the profile's author. We examined whether the specific type of self-disclosure on a professor's profile would affect students' perceptions of the professor and expectations of his classroom. We created six Facebook profiles for a fictitious male professor, each with a specific emphasis: politically conservative, politically liberal, religious, family oriented, socially oriented, or professional. Undergraduate students randomly viewed one profile and responded to questions that assessed their perceptions and expectations. The social professor was perceived as less skilled but more popular, while his profile was perceived as inappropriate and entertaining. Students reacted more strongly and negatively to the politically focused profiles in comparison to the religious, family, and professional profiles. Students reported being most interested in professional information on a professor's Facebook profile, yet they reported being least influenced by the professional profile. In general, students expressed neutrality about their interest in finding and friending professors on Facebook. These findings suggest that students have the potential to form perceptions about the classroom environment and about their professors based on the specific details disclosed in professors' Facebook profiles.
Do Facebook Status Updates Reflect Subjective Well-Being?
Liu, Pan; Tov, William; Kosinski, Michal; Stillwell, David J; Qiu, Lin
2015-07-01
Nowadays, millions of people around the world use social networking sites to express everyday thoughts and feelings. Many researchers have tried to make use of social media to study users' online behaviors and psychological states. However, previous studies show mixed results about whether self-generated contents on Facebook reflect users' subjective well-being (SWB). This study analyzed Facebook status updates to determine the extent to which users' emotional expression predicted their SWB-specifically their self-reported satisfaction with life. It was found that positive emotional expressions on Facebook did not correlate with life satisfaction, whereas negative emotional expressions within the past 9-10 months (but not beyond) were significantly related to life satisfaction. These findings suggest that both the type of emotional expressions and the time frame of status updates determine whether emotional expressions in Facebook status updates can effectively reflect users' SWB. The findings shed light on the characteristics of online social media and improve the understanding of how user-generated contents reflect users' psychological states.

2016-07-01
This cross-sectional study examined price-related promotions for tobacco products on Twitter. Through the Twitter Firehose, we obtained access to all public tweets posted between 6 December 2012 and 20 June 2013 that contained a keyword suggesting a tobacco-related product or behaviour (eg, cigarette, vaping) in addition to a keyword suggesting a price promotion (eg, coupon, discount). From this data set of 155 249 tweets, we constructed a stratified sampling frame based on the price-related keywords and randomly sampled 5000 tweets (3.2%). Tweets were coded for product type and promotion type. Non-English tweets and tweets unrelated to a tobacco or cessation price promotion were excluded, leaving an analytic sample of 2847 tweets. The majority of tweets (97.0%) mentioned tobacco products while 3% mentioned tobacco cessation products. E-cigarettes were the most frequently mentioned product (90.1%), followed by cigarettes (5.4%). The most common type of price promotion mentioned across all products was a discount. About a third of all e-cigarette-related tweets included a discount code. Banned or restricted price promotions comprised about 3% of cigarette-related tweets. This study demonstrates that the vast majority of tweets offering price promotions focus on e-cigarettes. Future studies should examine the extent to which Twitter users, particularly youth, notice or engage with these price promotion tweets. Published by the BMJ Publishing Group Limited.

We construct the Google matrix of the entire Twitter network, dated by July 2009, and analyze its spectrum and eigenstate properties including the PageRank and CheiRank vectors and 2DRanking of all nodes. Our studies show much stronger inter-connectivity between top PageRank nodes for the Twitter network compared to the networks of Wikipedia and British Universities studied previously. Our analysis allows to locate the top Twitter users which control the information flow on the network. We argue that this small fraction of the whole number of users, which can be viewed as the social network elite, plays the dominant role in the process of opinion formation on the network.
Facebook use during relationship termination: uncertainty reduction and surveillance.
Tong, Stephanie Tom
2013-11-01
Many studies document how individuals use Facebook to meet partners or develop and maintain relationships. Less is known about information-seeking behaviors during the stages of relationship termination. Relational dissolution is a socially embedded activity, and affordances of social network sites offer many advantages in reducing uncertainty after a breakup. A survey collected responses from 110 individuals who use Facebook to gather information about their romantic ex-partners. Results indicated that after breakup, partners may take advantage of the system's information visibility and the relative invisibility of movement depending on relational factors (initiator role and breakup uncertainty), social factors (perceived network approval of Facebook surveillance), and individual privacy concerns. This investigation addresses questions such as what type of information-seeking foci do individuals employ and how do individuals use Facebook as a form of surveillance? What factors motivate surveillance behavior?

The Twitter social microblogging database, which recently passed its tenth anniversary, is potentially a rich source of real-time and historical global information for science applications (beyond the by-now fairly familiar use of Twitter for natural hazards monitoring). Over the past several years, we have been exploring the feasibility of extracting from the Twitter data stream useful information for application to NASA precipitation research, with both "passive" and "active" participation by the twitterers. In the passive case, we have experimented with listening to the Twitter stream in real time for "precipitation" and related tweets (in different languages), applying basic filters for exact phrases, extracting location information, and mapping the resulting tweet distributions. In the active case, we have conducted preliminary experiments to evaluate different methods of engaging with potential participants. The time-varying set of "precipitation" tweets can be thought of as an organic network of rain gauges, potentially providing a widespread view of precipitation occurrence. The validation of satellite precipitation estimates is challenging, because many regions lack data or access to data, especially outside of the U.S. and in remote and developing areas. Mining the Twitter stream could augment these validation programs and, potentially, help tune existing algorithms. Though exploratory, our efforts thus far could significantly extend the application realm of Twitter, as a platform for citizen science, beyond natural hazards monitoring to science applications.

Previous investigations of the relationship between Facebook use and psychological well-being have most commonly considered variables relating to the quantity (e.g., time spent online) and underlying motivations (e.g., making new friends) of Facebook consumption. However, previous research has reached contradictory conclusions in that quantity of Facebook use has been linked to both higher and lower levels of psychological well-being. The current study investigated whether these contradictory findings of quantity of Facebook use could be explained by considering users' motivations for accessing Facebook. We predicted that quantity of use would be positively associated with psychological well-being when users primarily accessed Facebook to maintain existing relationships but negatively associated with psychological well-being when primarily accessed to create new relationships. In a sample of college undergraduates (N = 119), we found that the relationship of quantity of Facebook use on psychological well-being was moderated by the motivation of the user. Quantity of Facebook use was associated with higher levels of psychological well-being among users that accessed Facebook for friendship purposes but was negatively associated with psychological well-being among users that accessed Facebook for connection purposes (e.g., making new friends). We also replicated our results across dimensions of psychological well-being (e.g., anxiety and life satisfaction). The current findings provide initial evidence that quantity and motivations of Facebook use interact with potentially serious implications for psychological well-being and also provide a possible explanation for why quantity of Facebook use can be linked with both positive and negative psychological well-being.

2015-05-01
Twitter is a popular, publicly accessible, social media service that has proven useful in mapping large-scale events in real time. In this study, for the first time, the use of Twitter as a measure of auroral activity is investigated. Peaks in the number of aurora-related tweets are found to frequently coincide with geomagnetic disturbances (detection rate of 91%). Additionally, the number of daily aurora-related tweets is found to strongly correlate with several auroral strength proxies (ravg≈0.7). An examination is made of the bias for location and time of day within Twitter data, and a first-order correction of these effects is presented. Overall, the results suggest that Twitter can provide both specific details about an individual aurora and accurate real-time indication of when, and even from where, an aurora is visible.
Twitter as a tool for ophthalmologists.
Micieli, Robert; Micieli, Jonathan A
2012-10-01
Twitter is a social media web site created in 2006 that allows users to post Tweets, which are text-based messages containing up to 140 characters. It has grown exponentially in popularity; now more than 340 million Tweets are sent daily, and there are more than 140 million users. Twitter has become an important tool in medicine in a variety of contexts, allowing medical journals to engage their audiences, conference attendees to interact with one another in real time, and physicians to have the opportunity to interact with politicians, organizations, and the media in a manner that can be freely observed. There are also tremendous research opportunities since Twitter contains a database of public opinion that can be mined by keywords and hashtags. This article serves as an introduction to Twitter and surveys the peer-reviewed literature concerning its various uses and original studies. Opportunities for use in ophthalmology are outlined, and a recommended list of ophthalmology feeds on Twitter is presented. Overall, Twitter is an underutilized resource in ophthalmology and has the potential to enhance professional collegiality, advocacy, and scientific research.

In this study we present and empirically examine a new phenomenon related to social networking sites, such as Facebook, the “false Facebook-self.” Arguably false self-presentation on Facebook is a growing phenomenon, and in extreme cases; i.e., when ones Facebook image substantially deviates from their true image, it may serve as a gateway behavior to more problematic behaviors which may lead to psychological problems and even pathologies. In this study we show that certain users are more vulnerable to such false self-presentation than others. The study involved 258 Facebook users. Applying ANOVA and SEM analyses we show that users with low self-esteem and low trait authenticity are more likely than others to present a Facebook-self which deviates from their true selves. These social-interaction-related traits are influenced by one’s upbringing and the anxious and avoidant attachment styles he or she has developed. Several cases (7.5%) with large gaps between the true and false Facebook-self were detected, which implies that future research should consider the adverse consequences and treatments of high levels of false Facebook-self.

How to normalize Twitter counts? A first attempt based on journals in the Twitter Index.
Bornmann, Lutz; Haunschild, Robin
One possible way of measuring the broad impact of research (societal impact) quantitatively is the use of alternative metrics (altmetrics). An important source of altmetrics is Twitter, which is a popular microblogging service. In bibliometrics, it is standard to normalize citations for cross-field comparisons. This study deals with the normalization of Twitter counts (TC). The problem with Twitter data is that many papers receive zero tweets or only one tweet. In order to restrict the impact analysis on only those journals producing a considerable Twitter impact, we defined the Twitter Index (TI) containing journals with at least 80 % of the papers with at least 1 tweet each. For all papers in each TI journal, we calculated normalized Twitter percentiles (TP) which range from 0 (no impact) to 100 (highest impact). Thus, the highest impact accounts for the paper with the most tweets compared to the other papers in the journal. TP are proposed to be used for cross-field comparisons. We studied the field-independency of TP in comparison with TC. The results point out that the TP can validly be used particularly in biomedical and health sciences, life and earth sciences, mathematics and computer science, as well as physical sciences and engineering. In a first application of TP, we calculated percentiles for countries. The results show that Denmark, Finland, and Norway are the countries with the most tweeted papers (measured by TP).

2018-02-15
Despite the increasing prevalence of social media usage, the activity of dermatology journals and professional and patient-centered organizations on top social media platforms has not been investigated since 2012. We investigated a total of 124 dermatology journals, 242 professional organizations, and 78 patient-centered organizations to assess their presence and popularity on social media. Searches were conducted to identify journals and organizations on Facebook and Twitter. Similar searches were done for organizations on LinkedIn. The number of Facebook likes, Twitter followers, and LinkedIn followers of the dermatological entities were quantified. There were 22 (17.7%) dermatology journals active on Facebook and 21 (16.9%) on Twitter. Amongst the professional organizations, 114 (47.1%) were on Facebook, 69 (28.5%) on Twitter, and 50 (20.7%) on LinkedIn. In comparison, 68 (87.2%) patient-centered organizations were on Facebook, 56 (71.8%) on Twitter, and 56 (71.8%) on LinkedIn. Our results demonstrate that the popularity of dermatology journals and professional and patient-centered organizations on top social networking sites has grown markedly since 2012. Although the number of dermatology journals on social media has increased since 2012, their presence continues to trail behind professional and patient-centered dermatological organizations, suggesting underutilization of a valuable resource.

Facebook, a social network site, has been widely used among young adults. However, its potential to be used as a health promotion medium has not been fully examined. This study explored Facebook's potential for sharing human papillomavirus (HPV) vaccine information among female college students in Hawai‘i. Culturally tailored flyers and handouts were developed and distributed at one large university in Hawai‘i to recruit female college students between the age of 18 and 26 having an active Facebook account. Three focus group meetings were conducted to gather student perspectives about how information about HPV vaccine may be best shared via Facebook. We found that students believed Facebook is a good awareness tool but they needed more knowledge about the HPV vaccine to feel comfortable sharing the information. Participants preferred forwarding information to chatting about HPV. Some participants expressed concern that their Facebook friends would think the HPV vaccine information they forwarded on Facebook is spam. Participants suggested prefacing the posted HPV vaccine information with a personal note in their own words to make the message more interesting and relevant to their Facebook friends. Future interventions using Facebook to promote HPV vaccine could provide students with HPV vaccine information from credible sources and ask students to attach personal testimonials or endorsements while forwarding the information on Facebook.

Finding Street Gang Members on Twitter.
Balasuriya, Lakshika; Wijeratne, Sanjaya; Doran, Derek; Sheth, Amit
2016-08-01
Most street gang members use Twitter to intimidate others, to present outrageous images and statements to the world, and to share recent illegal activities. Their tweets may thus be useful to law enforcement agencies to discover clues about recent crimes or to anticipate ones that may occur. Finding these posts, however, requires a method to discover gang member Twitter profiles. This is a challenging task since gang members represent a very small population of the 320 million Twitter users. This paper studies the problem of automatically finding gang members on Twitter. It outlines a process to curate one of the largest sets of verifiable gang member profiles that have ever been studied. A review of these profiles establishes differences in the language, images, YouTube links, and emojis gang members use compared to the rest of the Twitter population. Features from this review are used to train a series of supervised classifiers. Our classifier achieves a promising F 1 score with a low false positive rate.

The primary objective of this study was to investigate how to incorporate human activity information in spatial analysis of crashes in urban areas using Twitter check-in data. This study used the data collected from the City of Los Angeles in the United States to illustrate the procedure. The following five types of data were collected: crash data, human activity data, traditional traffic exposure variables, road network attributes and social-demographic data. A web crawler by Python was developed to collect the venue type information from the Twitter check-in data automatically. The human activities were classified into seven categories by the obtained venue types. The collected data were aggregated into 896 Traffic Analysis Zones (TAZ). Geographically weighted regression (GWR) models were developed to establish a relationship between the crash counts reported in a TAZ and various contributing factors. Comparative analyses were conducted to compare the performance of GWR models which considered traditional traffic exposure variables only, Twitter-based human activity variables only, and both traditional traffic exposure and Twitter-based human activity variables. The model specification results suggested that human activity variables significantly affected the crash counts in a TAZ. The results of comparative analyses suggested that the models which considered both traditional traffic exposure and human activity variables had the best goodness-of-fit in terms of the highest R 2 and lowest AICc values. The finding seems to confirm the benefits of incorporating human activity information in spatial analysis of crashes using Twitter check-in data. Copyright © 2017 Elsevier Ltd. All rights reserved.
Exploring Hospitals' Use of Facebook: Thematic Analysis.
Kordzadeh, Nima; Young, Diana K
2018-05-16
Although health care organizations such as hospitals and clinics have widely embraced social media as a means to educate the community on health topics and increase patient loyalty and satisfaction, little is known about the content these organizations actually share when using social media channels. This study aimed to explore the types of content US hospitals post on their Facebook pages and how hospitals' Facebook activities differ with regard to content types. We collected and thematically analyzed more than 1700 Facebook posts made over a 3-month period by 17 US hospitals. During the first phase, the 2 researchers coded a set of 159 posts and created an initial thematic web of content. During the second phase, the researchers coded the remaining posts and then revised, refined, and validated the initial web of content accordingly. Coding consensus was achieved on 1184 of the 1548 analyzable sampled posts (76.49%). We identified a list of 13 unique health social media post themes and classified those themes into 3 thematic groups that included announcing, sharing, and recognizing activities. The most frequently used theme was sharing health information, which appeared in 35.81% (424/1184) of the posts analyzed. Such posts sought to provide health tips and advice to community members. Recognizing special days and recognizing employees were the second and third most frequently used themes, respectively, with 14.95% (177/1184) and 11.82% (140/1184) of the posts containing those themes. The frequency of these themes was surprising as the content was geared more toward stakeholders internal to the organization, although most previous literature has focused on social media as a tool to connect with external stakeholders. In addition, we found many of the posts involved more than one theme, and selected sets of themes co-occurred frequently. For example, 25.4% (45/177) of the posts recognizing special days also included content to share health information, and

Politicians' Twitter habits can vary considerably. Those who choose to use may do so as part of a broad discussion community or as a one-to-many broadcaster. Because each user sees a different mix of tweets, a politician seen by one user as interacting with the public may be seen by another as engaging in one-way communication, potentially prompting different evaluations of the politician, the ongoing discussion, or even Twitter itself. This study uses an experiment to test the effects of different engagement and framing styles in politician tweets on evaluations of the politician, other discussants, and Twitter itself. Findings suggest that politicians who use Twitter to broadcast, rather than engage with other users, not only receive worse evaluations themselves but that the negative evaluation carries over to other users discussing the same topics, as well as to evaluations of the utility of Twitter as an information source. This effect is attributed to intramedium interaction, in which reactions to one aspect of a multimedia object carry over to other aspects of the same object.

Background Twitter is home to many health professionals who send messages about a variety of health-related topics. Amid concerns about physicians posting inappropriate content online, more in-depth knowledge about these messages is needed to understand health professionals’ behavior on Twitter. Objective Our goal was to characterize the content of Twitter messages, specifically focusing on health professionals and their tweets relating to health. Methods We performed an in-depth content analysis of 700 tweets. Qualitative content analysis was conducted on tweets by health users on Twitter. The primary objective was to describe the general type of content (ie, health-related versus non-health related) on Twitter authored by health professionals and further to describe health-related tweets on the basis of the type of statement made. Specific attention was given to whether a tweet was personal (as opposed to professional) or made a claim that users would expect to be supported by some level of medical evidence (ie, a “testable” claim). A secondary objective was to compare content types among different users, including patients, physicians, nurses, health care organizations, and others. Results Health-related users are posting a wide range of content on Twitter. Among health-related tweets, 53.2% (184/346) contained a testable claim. Of health-related tweets by providers, 17.6% (61/346) were personal in nature; 61% (59/96) made testable statements. While organizations and businesses use Twitter to promote their services and products, patient advocates are using this tool to share their personal experiences with health. Conclusions Twitter users in health-related fields tweet about both testable claims and personal experiences. Future work should assess the relationship between testable tweets and the actual level of evidence supporting them, including how Twitter users—especially patients—interpret the content of tweets posted by health providers.

Twitter is home to many health professionals who send messages about a variety of health-related topics. Amid concerns about physicians posting inappropriate content online, more in-depth knowledge about these messages is needed to understand health professionals' behavior on Twitter. Our goal was to characterize the content of Twitter messages, specifically focusing on health professionals and their tweets relating to health. We performed an in-depth content analysis of 700 tweets. Qualitative content analysis was conducted on tweets by health users on Twitter. The primary objective was to describe the general type of content (ie, health-related versus non-health related) on Twitter authored by health professionals and further to describe health-related tweets on the basis of the type of statement made. Specific attention was given to whether a tweet was personal (as opposed to professional) or made a claim that users would expect to be supported by some level of medical evidence (ie, a "testable" claim). A secondary objective was to compare content types among different users, including patients, physicians, nurses, health care organizations, and others. Health-related users are posting a wide range of content on Twitter. Among health-related tweets, 53.2% (184/346) contained a testable claim. Of health-related tweets by providers, 17.6% (61/346) were personal in nature; 61% (59/96) made testable statements. While organizations and businesses use Twitter to promote their services and products, patient advocates are using this tool to share their personal experiences with health. Twitter users in health-related fields tweet about both testable claims and personal experiences. Future work should assess the relationship between testable tweets and the actual level of evidence supporting them, including how Twitter users-especially patients-interpret the content of tweets posted by health providers.

Despite the accumulating evidence on the positive and negative outcomes of Facebook use, how people perceive themselves to be subject to these outcomes as well as the consequences and mechanisms of these perceptions are underexplored. According to optimistic bias, Facebook users may perceive that bad things are more likely to happen to others than to themselves, while good things are more likely to happen to them than to others. The findings from an online survey among Facebook users indicate that the negative psychological and social outcomes of using Facebook were perceived to be more likely to happen to other Facebook users than to themselves, p<0.001. These self-other discrepant perceptions toward negative social events (e.g., Facebook cyberbullying and scams) significantly mediated one's willingness to support Internet regulation, Sobel z=2.49, p=0.01. For positive outcomes of Facebook use, the direction of optimistic bias was reversed, t(235) = -5.52, p<0.01, indicating that people minimized the likelihoods of experiencing positive events from Facebook while assessing that other Facebook users are prone to encounter those positive events. This reversal pattern emerged among those with negative attitudes toward, and low involvement with, Facebook. These findings demonstrate important and novel self-other discrepant perceptions concerning the risks and benefits of Facebook use.

The interpersonal, dialogic features of social networking sites have untapped potential for public health communication. We ran a Facebook advertising campaign to raise statewide awareness of Michigan's newborn screening and biobanking programs. We ran a Facebook advertising campaign to stimulate public engagement on the complex and sensitive issue of Michigan's newborn screening and biobank programs. We ran an 11-week, US $15,000 Facebook advertising campaign engaging Michigan Facebook users aged 18-64 years about the state's newborn screening and population biobank programs, and we used a novel "engagement spectrum" framework to contextualize and evaluate engagement outcomes ranging from observation to multi-way conversation. The campaign reached 1.88 million Facebook users, yielding a range of engagement outcomes across ad sets that varied by objective, content, budget, duration, and bid type. Ad sets yielded 9009 page likes (US $4125), 15,958 website clicks (US $5578), and 12,909 complete video views to 100% (US $3750). "Boosted posts" yielded 528 comments and 35,966 page post engagements (US $1500). Overall, the campaign led to 452 shares and 642 comments, including 176 discussing newborn screening and biobanking. Facebook advertising campaigns can efficiently reach large populations and achieve a range of engagement outcomes by diversifying ad types, bid types, and content. This campaign provided a population-based approach to communication that also increased transparency on a sensitive and complex topic by creating a forum for multi-way interaction.

From the Social media use by health professionals occurs in a digital environment where etiquette has yet to be solidly defined. The objectives of this study were to explore veterinarians' personal use of Facebook, knowledge of privacy settings, and factors related to sharing personal information online. All American Animal Hospital Association member veterinarians with a valid e-mail address (9469) were invited to complete an online survey about Facebook (e.g., time spent on Facebook, awareness of consequences, types of information posted). Questions assessing personality dimensions including trust, popularity, self-esteem and professional identity were included. The response rate was 17% (1594 of 9469); 72% of respondents (1148 of 1594) had a personal Facebook profile. Veterinarians were more likely to share information on Facebook than they would in general. Trust, need for popularity, and more time spent on Facebook predicted more disclosure of personal information on Facebook. Awareness of consequences and increased veterinary experience predicted lesser disclosure. As veterinary practices use Facebook to improve client services, they need also to manage risks associated with online disclosure by staff. Raising awareness of reputation management and consequences of posting certain types of information to Facebook is integral to protecting the individual, the practice, and the veterinary profession.
Twitter sentiment around the Earnings Announcement events
Grčar, Miha
2017-01-01
We investigate the relationship between social media, Twitter in particular, and stock market. We provide an in-depth analysis of the Twitter volume and sentiment about the 30 companies in the Dow Jones Industrial Average index, over a period of three years. We focus on Earnings Announcements and show that there is a considerable difference with respect to when the announcements are made: before the market opens or after the market closes. The two different timings of the Earnings Announcements were already investigated in the financial literature, but not yet in the social media. We analyze the differences in terms of the Twitter volumes, cumulative abnormal returns, trade returns, and earnings surprises. We report mixed results. On the one hand, we show that the Twitter sentiment (the collective opinion of the users) on the day of the announcement very well reflects the stock moves on the same day. We demonstrate this by applying the event study methodology, where the polarity of the Earnings Announcements is computed from the Twitter sentiment. Cumulative abnormal returns are high (2–4%) and statistically significant. On the other hand, we find only weak predictive power of the Twitter sentiment one day in advance. It turns out that it is important how to account for the announcements made after the market closes. These after-hours announcements draw high Twitter activity immediately, but volume and price changes in trading are observed only on the next day. On the day before the announcements, the Twitter volume is low, and the sentiment has very weak predictive power. A useful lesson learned is the importance of the proper alignment between the announcements, trading and Twitter data. PMID:28235103

Facebook Enhances Antidepressant Pharmacotherapy Effects
Mota Pereira, Jorge
2014-01-01
Treatment-resistant major depressive disorder (TR-MDD) is a complex condition, with very low remission rates. In recent years some studies have been conducted on the implementation of cognitive behavioral therapy and psychodynamic psychotherapy interventions via the Internet to MDD patients, and results have been promising. However, there have been no studies in patients with TR-MDD nor with the use of Facebook with the psychiatrist as “friend.” 60 TR-MDD patients were randomized to one of three groups: Facebook group with psychiatrist as “friend,” Facebook group without psychiatrist as “friend,” and control group (no Facebook use). Both Facebook groups spent at least 1 hour/day on Facebook, 7 days/week, during the 3 months. All patients maintained their usual pharmacotherapy. All participants were evaluated at baseline and at 1, 2, and 3 months for depressive symptoms using HAD17 and BDI-II. Results show that both Facebook groups had a decrease on HADM17 and BDI-II scores as well as higher remission and response rates than the control group, with better results if the psychiatrist was a “friend” on Facebook. Therefore, in TR-MDD, Facebook can be used as an effective enhancement therapy, adjuvant to pharmacological therapy with regular consultations, especially if the psychiatrist is the patient's online “friend.” PMID:24574930
Twitter predicts citation rates of ecological research
Peoples, Brandon K.; Midway, Stephen R.; Sackett, Dana K.; Lynch, Abigail; Cooney, Patrick B.
2016-01-01
The relationship between traditional metrics of research impact (e.g., number of citations) and alternative metrics (altmetrics) such as Twitter activity are of great interest, but remain imprecisely quantified. We used generalized linear mixed modeling to estimate the relative effects of Twitter activity, journal impact factor, and time since publication on Web of Science citation rates of 1,599 primary research articles from 20 ecology journals published from 2012–2014. We found a strong positive relationship between Twitter activity (i.e., the number of unique tweets about an article) and number of citations. Twitter activity was a more important predictor of citation rates than 5-year journal impact factor. Moreover, Twitter activity was not driven by journal impact factor; the ‘highest-impact’ journals were not necessarily the most discussed online. The effect of Twitter activity was only about a fifth as strong as time since publication; accounting for this confounding factor was critical for estimating the true effects of Twitter use. Articles in impactful journals can become heavily cited, but articles in journals with lower impact factors can generate considerable Twitter activity and also become heavily cited. Authors may benefit from establishing a strong social media presence, but should not expect research to become highly cited solely through social media promotion. Our research demonstrates that altmetrics and traditional metrics can be closely related, but not identical. We suggest that both altmetrics and traditional citation rates can be useful metrics of research impact.

Teachers' perceptions of Twitter for professional development.
Davis, Kerry
2015-01-01
The aim of this study was to determine how school teachers in the United States (US) perceived using Twitter as a means for professional development, engagement in communities of practice, and any benefits or drawbacks to participating in Twitter. This qualitative research utilized an embedded case design with three sources of data: (a) three consecutive months of tweet data from late 2011 archived on the host website, relating to #EdChat, a weekly online chat in Twitter about education issues; (b) interviews with 19 school teachers in the US who participated in the #EdChat online discussions in Twitter; and (c) Twitter bio and Tweet data of the 19 teachers interviewed. All data were entered into NVIVO (QSR International Pty. Ltd., Doncaster, Australia) for content thematic coding, and The Communities of Practice and Connectivist Conceptual Framework was used to inform this analysis. The researchers' interpretations were verified with participants, and data triangulated across all sources to strengthen confidence in the results. Five main themes and 17 subthemes emerged from the data across all sources. The main themes were teachers' perceptions of sharing knowledge and resources, Twitter promoting a sense of belonging, Twitter providing meaningful professional development, and teachers' views on the technical benefits and drawbacks of using Twitter. Regardless of years teaching, subject area, or age, educators perceived Twitter as providing an online forum to reflect upon practice, exchange knowledge and experience, and be in the presence of supportive colleagues. While participants experienced the pace and volume of information as being overwhelming at times, educators developed skills to managing this and perceived discussions to be learner-centered and supportive. Teachers valued the sense of community and learning that they reported were not otherwise available in their own physical workplace. Overall, participants perceived that the benefits of participation
Leveraging Social Media to Promote Evidence-Based Continuing Medical Education

Importance New dissemination methods are needed to engage physicians in evidence-based continuing medical education (CME). Objective To examine the effectiveness of social media in engaging physicians in non-industry-sponsored CME. Design We tested the effect of different media platforms (e-mail, Facebook, paid Facebook and Twitter), CME topics, and different “hooks” (e.g., Q&A, clinical pearl and best evidence) on driving clicks to a landing site featuring non-industry sponsored CME. We modelled the effects of social media platform, CME topic, and hook using negative binomial regression on clicks to a single landing site. We used clicks to landing site adjusted for exposure and message number to calculate rate ratios. To understand how physicians interact with CME content on social media, we also conducted interviews with 10 physicians. Setting The National Physicians Alliance (NPA) membership. Participants NPA e-mail recipients, Facebook followers and friends, and Twitter followers. Main Outcomes and Measures Clicks to the NPA’s CME landing site. Results On average, 4,544 recipients received each message. Messages generated a total of 592 clicks to the landing site, for a rate of 5.4 clicks per 1000 recipients exposed. There were 5.4 clicks from e-mail, 11.9 clicks from Facebook, 5.5 clicks from paid Facebook, and 6.9 clicks from Twitter to the landing site for 1000 physicians exposed to each of 4 selected CME modules. A Facebook post generated 2.3x as many clicks to the landing site as did an e-mail after controlling for participant exposure, hook type and CME topic (p<0.001). Twitter posts (p = 0.13) and paid Facebook posts (p = 0.06) were not statistically different from e-mail in generating clicks to the landing site. Use of different hooks to engage physicians had no impact on clicks to the landing site. Interviews with physicians suggested that social media might not be a preferred vehicle for disseminating CME. Conclusions Social media has a modest

This study assesses the prevalence of use of the most commonly used social media sites among private radiology groups (PRGs) and academic radiology departments (ARDs). The 50 largest PRGs and the 50 ARDs with the highest level of funding from the National Institutes of Health were assessed for presence of a radiology-specific social media account on Facebook, Twitter, Instagram, Pinterest, YouTube, and LinkedIn. Measures of organizational activity and end-user activity were collected, including the number of posts and followers, as appropriate; between-group comparisons were performed. PRGs adopted Facebook 12 months earlier (P = .02) and Twitter 18 months earlier (P = .02) than did ARDs. A total of 76% of PRGs maintained ≥1 account on the social media sites included in the study, compared with 28% of ARDs (P < .0001). The prevalence of having an account on the social media sites for PRGs was: Facebook, 66%; LinkedIn, 56%; Twitter, 42%; YouTube, 20%; Pinterest, 4%; and Instagram, 2%. The prevalence of radiology-specific social media accounts for ARDs was: Facebook, 18%; LinkedIn, 0%; Twitter, 24%; YouTube, 6%; Pinterest, 0%; and Instagram, 0%. There was no significant difference between ARDs and PRGs in measures of end-user or organizational activity on Facebook or Twitter. Use of social media in health care is emerging as mainstream, with PRGs being early adopters of Facebook and Twitter in comparison with ARDs. Competitive environments and institutional policies may be strong factors that influence how social media is used by radiologists at the group and department levels.

Finding Street Gang Members on Twitter
Balasuriya, Lakshika; Wijeratne, Sanjaya; Doran, Derek; Sheth, Amit
2017-01-01
Most street gang members use Twitter to intimidate others, to present outrageous images and statements to the world, and to share recent illegal activities. Their tweets may thus be useful to law enforcement agencies to discover clues about recent crimes or to anticipate ones that may occur. Finding these posts, however, requires a method to discover gang member Twitter profiles. This is a challenging task since gang members represent a very small population of the 320 million Twitter users. This paper studies the problem of automatically finding gang members on Twitter. It outlines a process to curate one of the largest sets of verifiable gang member profiles that have ever been studied. A review of these profiles establishes differences in the language, images, YouTube links, and emojis gang members use compared to the rest of the Twitter population. Features from this review are used to train a series of supervised classifiers. Our classifier achieves a promising F1 score with a low false positive rate. PMID:28713880

The aim of this study was to investigate the Twitter experiences of adults with severe communication disabilities who use augmentative and alternative communication (AAC) to inform Twitter training and further research on the use of Twitter in populations with communication disabilities. This mixed methods research included five adults with severe communication disabilities who use AAC. It combined (a) quantitative analysis of Twitter networks and (b) manual coding of tweets with (c) narrative interviews with participants on their Twitter experiences and results. The five participants who used AAC and Twitter were diverse in their patterns and experiences of using Twitter. Twitter networks reflected interaction with a close-knit network of people rather than with the broader publics on Twitter. Conversational, Broadcast and Pass Along tweets featured most prominently, with limited use of News or Social Presence tweets. Tweets appeared mostly within each participant's micro- or meso-structural layers of Twitter. People who use AAC report positive experiences in using Twitter. Obtaining help in Twitter, and engaging in hashtag communities facilitated higher frequency of tweets and establishment of Twitter networks. Results reflected an inter-connection of participant Twitter networks that might form part of a larger as yet unexplored emergent community of people who use AAC in Twitter.

The purpose of this study was to assess messages posted by mothers of children with type 1 diabetes in the Italian Facebook group "Mamme e diabete" using computerized text analysis. The data suggest that these mothers use online discussion boards as a place to seek and provide information to better manage the disease's daily demands-especially those tasks linked to insulin correction and administration, control of food intake, and bureaucratic duties, as well as to seek and give encouragement and to share experiences regarding diabetes and related impact on their life. The implications of these findings for the management of diabetes are discussed.
Social media-sprint out of the gates!

Not having a Twitter account or a Facebook fan page for your employer, or for yourself, is no longer an option if you plan to participate in social media. I preface this article with the statement that many things could possibly change on Twitter and Facebook in 1 month's time from writing this article and it's publishing. We will focus on Twitter and Facebook because they can have the greatest impact with the least amount of effort, and they are the most popular. By creating an account for each and connecting them together, you ensure a "sprint" out of the social media gate versus a slow jog; so let's get started!

Comparative effects of Facebook and conventional media on body image dissatisfaction.
Cohen, Rachel; Blaszczynski, Alex
2015-01-01
Appearance comparison has consistently been shown to engender body image dissatisfaction. To date, most studies have demonstrated this relationship between appearance comparison and body image dissatisfaction in the context of conventional media images depicting the thin-ideal. Social comparison theory posits that people are more likely to compare themselves to similar others. Since social media forums such as Facebook involve one's peers, the current study aimed to determine whether the relationship between appearance comparison and body image dissatisfaction would be stronger for those exposed to social media images, compared to conventional media images. A sample of 193 female first year university students were randomly allocated to view a series of either Facebook or conventional media thin-ideal images. Participants completed questionnaires assessing pre- and post- image exposure measures of thin-ideal internalisation, appearance comparison, self-esteem, Facebook use and eating disorder risk. Type of exposure was not found to moderate the relationship between appearance comparison and changes in body image dissatisfaction. When analysed according to exposure type, appearance comparison only significantly predicted body image dissatisfaction change for those exposed to Facebook, but not conventional media. Facebook use was found to predict higher baseline body image dissatisfaction and was associated with higher eating disorder risk. The findings suggest the importance of extending the body image dissatisfaction literature by taking into account emerging social media formats. It is recommended that interventions for body image dissatisfaction and eating disorders consider appearance comparison processes elicited by thin-ideal content on social media forums, such as Facebook, in addition to conventional media.
Twitter Use in the Hematopoietic Cell Transplantation Community.
Patel, Sagar S; Majhail, Navneet S
2018-02-01
Social media has revolutionized the access and exchange of information in healthcare. The microblogging platform Twitter has been used by blood and marrow transplant physicians over the last several years with increasing enthusiasm. We review the adoption of Twitter in the transplant community and its implications on clinical care, education, and research. Twitter allows instantaneous access to the latest research publications, developments at national and international meetings, networking with colleagues, participation in advocacy, and promoting available clinical trials. Additionally, Twitter serves as a gateway for resources dedicated to education and support for patients undergoing transplantation. We demonstrate the utilization and various applications in using Twitter among hematopoietic cell transplant healthcare professionals, patients, and other affiliated stakeholders. Professionalism concerns with clinician use of such social media platforms, however, also exist. Overall, Twitter has enhanced and increased the opportunities for engagement in the transplant community.
Social support for physical activity-role of Facebook with and without structured intervention.
Cavallo, David N; Tate, Deborah F; Ward, Dianne S; DeVellis, Robert F; Thayer, Linden M; Ammerman, Alice S
2014-12-01
Despite their widespread use and extensive technical features, little is known about how to use online social networking sites to increase physical activity. This study aims to examine Facebook engagement among participants in the online social networking arm of a randomized controlled physical activity promotion trial (n = 67). Facebook communications were double coded and analyzed using ATLAS.ti. Regression procedures were used to determine predictors of Facebook use and associations between types of use and changes in perceived social support and physical activity. Changes in perceived social support and physical activity were more strongly associated with participants' individual Facebook use than use of the Facebook intervention group. The way social media sites are used in intervention design could have an impact on their effects. Including existing friends in interventions and using applications that incorporate intervention activities into a more naturalistic use of Facebook may improve the efficacy of future interventions.

Extending previous research on positive and negative correlates of Facebook use for individuals' outcomes, this study examined male and female dating partners' (n=58 couples) Facebook use and portrayals of their intimate relationship on the Facebook profile. Confirming hypotheses from compatibility theories of mate selection, partners demonstrated similar Facebook intensity (e.g., usage, connection to Facebook), and were highly likely to portray their relationship on their Facebook profiles in similar ways (i.e., display partnered status and show their partner in profile picture). These Facebook profile choices played a role in the overall functioning of the relationship, with males' indications of a partnered status linked with higher levels of their own and their partners' (marginal) relationship satisfaction, and females' displays of their partner in their profile picture linked with higher levels of their own and their partners' relationship satisfaction. Finally, male and female reports of having had disagreements over the Facebook relationship status was associated with lower level of females' but not males' relationship satisfaction, after accounting for global verbal conflict. Thus, the findings point to the unique contribution of Facebook disagreements to intimate relationship functioning. Results from this study encourage continued examination of technology use and behaviors in contexts of intimate relationships.
Motives to use Facebook and problematic Facebook use in adolescents.
Marino, Claudia; Mazzieri, Elena; Caselli, Gabriele; Vieno, Alessio; Spada, Marcantonio M
2018-05-30
Background and aims There is a growing body of evidence suggesting that problematic Facebook use (PFU) is an emerging problem, particularly among adolescents. Although a number of motivations explaining why people engage in frequent Facebook use have been identified, less is known about the specific psychological needs underlying PFU. The aim of this study is to test a model designed to assess the unique contribution of psychological motives for using Facebook to the different PFU dimensions in a sample of adolescents. Methods A total of 864 Italian adolescents participated in the study. Multivariate multiple regression was run to test whether the four motives were differently associated with problematic dimensions. Results The results showed that the two motives with negative valence (coping and conformity) were significantly linked to the five dimensions of PFU, whereas the two motives with positive valence (enhancement and social) appeared to be weaker predictors for three out of these five dimensions. Discussion and conclusion In conclusion, psychological motives for using Facebook appeared to significantly contribute to explaining PFU among adolescents, and should be considered by researchers and educational practitioners.

Over one billion people use Facebook as a platform for social interaction and self-presentation making it one of the most popular online sites. The aim of the present study was to investigate differences in various personality traits and mental health variables between Facebook users and people who do not use this platform. The data of 945 participants (790 Facebook users, 155 Facebook non-users) were collected. Results indicate that Facebook users score significantly higher on narcissism, self-esteem and extraversion than Facebook non-users. Furthermore, they have significantly higher values of social support, life satisfaction and subjective happiness. Facebook non-users have (marginally) significantly higher values of depression symptoms than Facebook users. In both groups, extraversion, self-esteem, happiness, life satisfaction, resilience and social support, on the one hand, and depression, anxiety and stress symptoms, on the other hand, are negatively correlated. Neuroticism is positively associated with depression, anxiety and stress symptoms. However, significant differences exist between Facebook users and Facebook non-users regarding some associations of personality traits and mental health variables. Compared to Facebook non-users, the present results indicate that Facebook users have higher values of certain personality traits and positive variables protecting mental health. These findings are of particular interest considering the high importance of social online-platforms in the daily life of many people.
Twitter, Millennials, and Nursing Education Research.
Stephens, Teresa M; Gunther, Mary E
2016-01-01
This article reports the use of Twitter as an intervention delivery method in a multisite experimental nursing research study. A form of social networking, Twitter is considered a useful means of communication, particularly with millennials. This method was chosen based on current literature exploring the characteristics of millennial students. Ahern's Model of Adolescent Resilience served as the theoretical framework. Participants were 70 junior-level baccalaureate nursing students, ages 19-23, at two state-supported universities. Twitter was found to be a convenient, cost-effective, and enjoyable means of intervention delivery for the researcher. Participants in the experimental and control groups expressed positive feelings about the use of Twitter. The findings contribute to future efforts to use social media in nursing research and education to increase faculty-student engagement, promote critical reflection, provide social support, reinforce course content, and increase the sense of community.
Snapchat elicits more jealousy than Facebook: a comparison of Snapchat and Facebook use.
Utz, Sonja; Muscanell, Nicole; Khalid, Cameran
2015-03-01
Recent news in the media has suggested that younger people are using popular social media such as Facebook less and are quickly adopting newer media, such as the self-destructing app Snapchat. Snapchat is unique in that it erases messages several seconds after they have been sent, affording its users a higher level of privacy. Yet, little research exists on Snapchat use in general, let alone its broader psychological implications. This article offers a preliminary comparison of Snapchat and Facebook use and psychological effects on romantic jealousy. General motives for using Snapchat and Facebook are examined, as well as the nature of the content that Snapchat users most frequently share. Further, because of the differences in privacy and persistence of information, potential psychological effects in the domain of romantic jealousy are also examined, which has been widely studied on Facebook in the last few years. Findings show that the main difference in motives were that Snapchat was used more for flirting and finding new love interests, whereas Facebook was still the main social networking site used for keeping in touch with friends. Further, when presenting users with a series of potentially jealousy provoking scenarios, Snapchat elicited higher levels of jealousy than did Facebook. These findings are explained based on an affordance approach.

How U.S. children's hospitals use social media: A mixed methods study.
Wong, Charlene A; Ostapovich, Gabrielle; Kramer-Golinkoff, Emily; Griffis, Heather; Asch, David A; Merchant, Raina M
2016-03-01
Social media provide new channels for hospitals to engage with communities, a goal of increasing importance as non-profit hospitals face stricter definitions of community benefit under the Affordable Care Act. We describe the variability in social media presence among US children's hospitals and the distribution of their Facebook content curation. Social media data from freestanding children's hospitals were extracted from September-November 2013. Social media adoption was reviewed for each hospital-generated Facebook, Twitter, YouTube, Google+ and Pinterest platform. Facebook page (number of Likes) and Twitter account (number of followers) engagement were examined by hospital characteristics. Facebook posts from each hospital over a 6-week period were thematically characterized. We reviewed 5 social media platforms attributed to 45 children's hospitals and 2004 associated Facebook posts. All hospitals maintained Facebook and Twitter accounts and most used YouTube (82%), Google+ (53%) and Pinterest (69%). Larger hospitals were more often high performers for Facebook (67% versus 10%, p<0.01) and Twitter (75% versus 17%, p<0.05) engagement than small hospitals. The most common Facebook post-themes were hospital promotion 35% (706), education and information 35% (694), community partnership or benefit 24% (474), fundraising 21% (426), and narratives 12% (241). Of health education posts, 73% (509) provided pediatric health supervision and anticipatory guidance. Social media adoption by US children's hospitals was widespread. Beyond its traditional marketing role, social media can serve as a conduit for health education, engagement with communities, including community benefit. Copyright © 2015 Elsevier Inc.

Measuring Message Propagation and Social Influence on Twitter.com
NASA Astrophysics Data System (ADS)
Ye, Shaozhi; Wu, S. Felix
Although extensive studies have been conducted on online social networks (OSNs), it is not clear how to characterize information propagation and social influence, two types of important but not well defined social behavior. This paper presents a measurement study of 58M messages collected from 700K users on Twitter.com, a popular social medium. We analyze the propagation patterns of general messages and show how breaking news (Michael Jackson's death) spread through Twitter. Furthermore, we evaluate different social influences by examining their stabilities, assessments, and correlations. This paper addresses the complications as well as challenges we encounter when measuring message propagation and social influence on OSNs. We believe that our results here provide valuable insights for future OSN research.

Understanding Human Mobility from Twitter
Jurdak, Raja; Zhao, Kun; Liu, Jiajun; AbouJaoude, Maurice; Cameron, Mark; Newth, David
2015-01-01
Understanding human mobility is crucial for a broad range of applications from disease prediction to communication networks. Most efforts on studying human mobility have so far used private and low resolution data, such as call data records. Here, we propose Twitter as a proxy for human mobility, as it relies on publicly available data and provides high resolution positioning when users opt to geotag their tweets with their current location. We analyse a Twitter dataset with more than six million geotagged tweets posted in Australia, and we demonstrate that Twitter can be a reliable source for studying human mobility patterns. Our analysis shows that geotagged tweets can capture rich features of human mobility, such as the diversity of movement orbits among individuals and of movements within and between cities. We also find that short- and long-distance movers both spend most of their time in large metropolitan areas, in contrast with intermediate-distance movers’ movements, reflecting the impact of different modes of travel. Our study provides solid evidence that Twitter can indeed be a useful proxy for tracking and predicting human movement. PMID:26154597

Abstract Purpose: The aim of this study was to investigate the Twitter experiences of adults with severe communication disabilities who use augmentative and alternative communication (AAC) to inform Twitter training and further research on the use of Twitter in populations with communication disabilities. Method: This mixed methods research included five adults with severe communication disabilities who use AAC. It combined (a) quantitative analysis of Twitter networks and (b) manual coding of tweets with (c) narrative interviews with participants on their Twitter experiences and results. Results: The five participants who used AAC and Twitter were diverse in their patterns and experiences of using Twitter. Twitter networks reflected interaction with a close-knit network of people rather than with the broader publics on Twitter. Conversational, Broadcast and Pass Along tweets featured most prominently, with limited use of News or Social Presence tweets. Tweets appeared mostly within each participant's micro- or meso-structural layers of Twitter. Conclusions: People who use AAC report positive experiences in using Twitter. Obtaining help in Twitter, and engaging in hashtag communities facilitated higher frequency of tweets and establishment of Twitter networks. Results reflected an inter-connection of participant Twitter networks that might form part of a larger as yet unexplored emergent community of people who use AAC in Twitter.Implications for RehabilitationTwitter can be used as an important vehicle for conversation and a forum for people with communication disabilities to exchange information and participate socially in online communities.It is important that information and resources relating to the effective use of Twitter for a range of purposes are made available to people with communication disabilities who wish to take up or maintain use of Twitter.People with communication disabilities might benefit from support in using Twitter to meet their goals
Twittering About Research: A Case Study of the World's First Twitter Poster Competition.
Randviir, Edward P; Illingworth, Samuel M; Baker, Matthew J; Cude, Matthew; Banks, Craig E
2015-01-01
The Royal Society of Chemistry held, to our knowledge, the world's first Twitter conference at 9am on February 5 (th), 2015. The conference was a Twitter-only conference, allowing researchers to upload academic posters as tweets, replacing a physical meeting. This paper reports the details of the event and discusses the outcomes, such as the potential for the use of social media to enhance scientific communication at conferences. In particular, the present work argues that social media outlets such as Twitter broaden audiences, speed up communication, and force clearer and more concise descriptions of a researcher's work. The benefits of poster presentations are also discussed in terms of potential knowledge exchange and networking. This paper serves as a proof-of-concept approach for improving both the public opinion of the poster, and the enhancement of the poster through an innovative online format that some may feel more comfortable with, compared to face-to-face communication.

This article describes a novel triangulation methodological approach for identifying twitter activity of regional active twitter users during the 2013 Hattiesburg EF-4 Tornado. A data extraction and geographically centered filtration approach was utilized to generate Twitter data for 48 hrs pre- and post-Tornado. The data was further validated using six sigma approach utilizing GPS data. The regional analysis revealed a total of 81,441 tweets, 10,646 Twitter users, 27,309 retweets and 2637 tweets with GPS coordinates. Twitter tweet activity increased 5 fold during the response to the Hattiesburg Tornado. Retweeting activity increased 2.2 fold. Tweets with a hashtag increased 1.4 fold. Twitter was an effective disaster risk reduction tool for the Hattiesburg EF-4 Tornado 2013.

Twitter use in physics conferences.
Webb, Stephen
An analysis of Twitter use in 116 conferences suggests that the service is used more extensively at PACS10 conferences (those devoted to the physics of elementary particles and fields) and PACS90 conferences (those devoted to geophysics, astronomy, and astrophysics) than at conferences in other fields of physics. Furthermore, Twitter is used in a qualitatively different manner. A possible reason for these differences is discussed.

Twitter as a Tool for Health Research: A Systematic Review.
Sinnenberg, Lauren; Buttenheim, Alison M; Padrez, Kevin; Mancheno, Christina; Ungar, Lyle; Merchant, Raina M
2017-01-01
Researchers have used traditional databases to study public health for decades. Less is known about the use of social media data sources, such as Twitter, for this purpose. To systematically review the use of Twitter in health research, define a taxonomy to describe Twitter use, and characterize the current state of Twitter in health research. We performed a literature search in PubMed, Embase, Web of Science, Google Scholar, and CINAHL through September 2015. We searched for peer-reviewed original research studies that primarily used Twitter for health research. Two authors independently screened studies and abstracted data related to the approach to analysis of Twitter data, methodology used to study Twitter, and current state of Twitter research by evaluating time of publication, research topic, discussion of ethical concerns, and study funding source. Of 1110 unique health-related articles mentioning Twitter, 137 met eligibility criteria. The primary approaches for using Twitter in health research that constitute a new taxonomy were content analysis (56%; n = 77), surveillance (26%; n = 36), engagement (14%; n = 19), recruitment (7%; n = 9), intervention (7%; n = 9), and network analysis (4%; n = 5). These studies collectively analyzed more than 5 billion tweets primarily by using the Twitter application program interface. Of 38 potential data features describing tweets and Twitter users, 23 were reported in fewer than 4% of the articles. The Twitter-based studies in this review focused on a small subset of data elements including content analysis, geotags, and language. Most studies were published recently (33% in 2015). Public health (23%; n = 31) and infectious disease (20%; n = 28) were the research fields most commonly represented in the included studies. Approximately one third of the studies mentioned ethical board approval in their articles. Primary funding sources included federal (63%), university (13%), and foundation

Analyzing health organizations' use of Twitter for promoting health literacy.
Park, Hyojung; Rodgers, Shelly; Stemmle, Jon
2013-01-01
This study explored health-related organizations' use of Twitter in delivering health literacy messages. A content analysis of 571 tweets from health-related organizations revealed that the organizations' tweets were often quoted or retweeted by other Twitter users. Nonprofit organizations and community groups had more tweets about health literacy than did other types of health-related organizations examined, including health business corporations, educational institutions, and government agencies. Tweets on health literacy topics focused predominantly on using simple language rather than complicated language. The results suggest that health organizations need a more strategic approach to managing positive organizational self-presentations in order to create an optimal level of exposure on social networking sites.

Inconsistent results have been reported concerning the relationships between SNS usage and loneliness. The current two-wave panel study with a one year interval examined the possibility of reciprocal and curvilinear relationships between active public Facebook use and adolescents' social/emotional loneliness. Belgian adolescents from fifteen high schools participated (N = 1188, 55% male). The results showed a U-shaped relationship between (1) active Facebook use and social/emotional loneliness and (2) emotional loneliness and active Facebook use. Specifically, active Facebook use predicted decreased social/emotional loneliness among low to moderate users, while among heavy users, increased levels of social/emotional loneliness were predicted by active Facebook use. Emotional loneliness predicted higher active Facebook use among lonely adolescents. At the same time, emotional loneliness predicted decreased active Facebook use among adolescents who did not feel lonely. These findings stress to consider different types of loneliness, and reciprocal and curvilinear relationships in future social media research.

Having Fun on Facebook?: Mothers' Enjoyment as a Moderator of Mental Health and Facebook Use.
Kaufmann, Renee; Buckner, Marjorie M; Ledbetter, Andrew M
2017-08-01
This study reports results of a study that examined the extent to which contextual factors (i.e., income level and number of children) might predict a mother's mental health quality, which, in turn, may predict level of engagement with Facebook. Results supported this model, finding that mothers with more children and lower income possess lower mental health quality, and lower mental health quality predicted more frequent Facebook use. However, this pattern was qualified by a mother's level of enjoyment of Facebook, such that mental health quality did not significantly predict Facebook intensity when enjoyment of Facebook was low. This research extends practitioners' knowledge of mothers' mental health quality by identifying a behavior that may indicate lower mental health quality and enhance abilities to recognize mothers who may need support or treatment. Future directions for this research are included.

In this paper we will try to define the utility of Facebook's Personal Page marketing method. This tool that Facebook provides, is modelled and simulated using iThink in the context of a Facebook marketing agency. The paper has leveraged the system's dynamic paradigm to conduct Facebook marketing tools and methods modelling, using iThink™ system to implement them. It uses the design science research methodology for the proof of concept of the models and modelling processes. The following model has been developed for a social media marketing agent/company, Facebook platform oriented and tested in real circumstances. This model is finalized through a number of revisions and iterators of the design, development, simulation, testing and evaluation processes. The validity and usefulness of this Facebook marketing model for the day-to-day decision making are authenticated by the management of the company organization. Facebook's Personal Page method can be adjusted, depending on the situation, in order to maximize the total profit of the company which is to bring new customers, keep the interest of the old customers and deliver traffic to its website.

Schizophrenia is a rare but devastating condition, affecting about 1% of the world's population and resulting in about 2% of the US health care expenditure. Major impediments to appropriate and timely care include misconceptions, high levels of stigma, and lack of public awareness. Facebook offers novel opportunities to understand public awareness and information access related to schizophrenia, and thus can complement survey-based approaches to assessing awareness that are limited in scale, robustness, and temporal and demographic granularity. The aims of this study were to (1) construct an index that measured the awareness of different demographic groups around schizophrenia-related information on Facebook; (2) study how this index differed across demographic groups and how it correlated with complementary Web-based (Google Trends) and non-Web-based variables about population well-being (mental health indicators and infrastructure), and (3) examine the relationship of Facebook derived schizophrenia index with other types of online activity as well as offline health and mental health outcomes and indicators. Data from Facebook's advertising platform was programmatically collected to compute the proportion of users in a target demographic group with an interest related to schizophrenia. On consultation with a clinical expert, several topics were combined to obtain a single index measuring schizophrenia awareness. This index was then analyzed for differences across US states, gender, age, ethnic affinity, and education level. A statistical approach was developed to model a group's awareness index based on the group's characteristics. Overall, 1.03% of Facebook users in the United States have a schizophrenia-related interest. The schizophrenia awareness index (SAI) is higher for females than for males (1.06 vs 0.97, P<.001), and it is highest for the people who are aged 25-44 years (1.35 vs 1.03 for all ages, P<.001). The awareness index drops for higher education
Mining twitter to understand the smoking cessation barriers.

Smoking cessation is challenging and lack of positive support is a known major barrier to quitting cigarettes. Previous studies have suggested that social influences might increase smokers' awareness of social norms for appropriate behavior, which might lead to smoking cessation. Although social media use is increasing among young adults in the United States, research on the relationship between social media use and smoking cessation is lacking. Twitter has provided a rich source of information for researchers, but no overview exists as to how the field uses Twitter in smoking cessation research. To the best of our knowledge, this study conducted a data mining analysis of Twitter to assess barriers to smoking cessation. In conclusion, Twitter is a cost-effective tool with the potential to disseminate information on the benefits of smoking cessation and updated research to the Twitter community on a global scale.
Cultural influences on Facebook photographs.

Prior research in social psychology indicates that East Asians from collectivistic and interdependent sociocultural systems are more sensitive to contextual information than Westerners, whereas Westerners with individualistic and independent representation have a tendency to process focal and discrete attributes of the environment. Here we have demonstrated that such systematic cultural variations can also be observed in cyberspace, focusing on self-presentation of photographs on Facebook, the most popular worldwide online social network site. We examined cultural differences in face/frame ratios for Facebook profile photographs in two studies. For Study 1, 200 digital profile face photographs of active Facebook users were randomly selected from native and immigrant Taiwanese and Americans. For Study 2, 312 Facebook profiles of undergraduate students of six public universities in East Asia (Hong Kong, Singapore, and Taiwan) and the United States (California and Texas) were randomly selected. Overall, the two studies clearly showed that East Asian Facebook users are more likely to deemphasize their faces compared to Americans. Specifically, East Asians living in Hong Kong, Singapore, and Taiwan exhibited a predilection for context inclusiveness in their profile photographs, whereas Americans tended to prioritize their focal face at the expense of the background. Moreover, East Asian Facebook users had lower intensity of facial expression than Americans on their photographs. These results demonstrate marked cultural differences in context-inclusive styles versus object-focused styles between East Asian and American Facebook users. Our findings extend previous findings from the real world to cyberspace, and provide a novel approach to investigate cognition and behaviors across cultures by using Facebook as a data collection platform.

Facebook, the most popular social network with over one billion daily users, provides rich opportunities for its use in the health domain. Though much of Facebook's data are not available to outsiders, the company provides a tool for estimating the audience of Facebook advertisements, which includes aggregated information on the demographics and interests, such as weight loss or dieting, of Facebook users. This paper explores the potential uses of Facebook ad audience estimates for eHealth by studying the following: (1) for what type of health conditions prevalence estimates can be obtained via social media and (2) what type of marker interests are useful in obtaining such estimates, which can then be used for recruitment within online health interventions. The objective of this study was to understand the limitations and capabilities of using Facebook ad audience estimates for public health monitoring and as a recruitment tool for eHealth interventions. We use the Facebook Marketing application programming interface to correlate estimated sizes of audiences having health-related interests with public health data. Using several study cases, we identify both potential benefits and challenges in using this tool. We find several limitations in using Facebook ad audience estimates, for example, using placebo interest estimates to control for background level of user activity on the platform. Some Facebook interests such as plus-size clothing show encouraging levels of correlation (r=.74) across the 50 US states; however, we also sometimes find substantial correlations with the placebo interests such as r=.68 between interest in Technology and Obesity prevalence. Furthermore, we find demographic-specific peculiarities in the interests on health-related topics. Facebook's advertising platform provides aggregate data for more than 190 million US adults. We show how disease-specific marker interests can be used to model prevalence rates in a simple and intuitive manner
Twitter as a Tool for Health Research: A Systematic Review
Sinnenberg, Lauren; Buttenheim, Alison M.; Padrez, Kevin; Mancheno, Christina; Ungar, Lyle
2017-01-01
Background. Researchers have used traditional databases to study public health for decades. Less is known about the use of social media data sources, such as Twitter, for this purpose. Objectives. To systematically review the use of Twitter in health research, define a taxonomy to describe Twitter use, and characterize the current state of Twitter in health research. Search methods. We performed a literature search in PubMed, Embase, Web of Science, Google Scholar, and CINAHL through September 2015. Selection criteria. We searched for peer-reviewed original research studies that primarily used Twitter for health research. Data collection and analysis. Two authors independently screened studies and abstracted data related to the approach to analysis of Twitter data, methodology used to study Twitter, and current state of Twitter research by evaluating time of publication, research topic, discussion of ethical concerns, and study funding source. Main results. Of 1110 unique health-related articles mentioning Twitter, 137 met eligibility criteria. The primary approaches for using Twitter in health research that constitute a new taxonomy were content analysis (56%; n = 77), surveillance (26%; n = 36), engagement (14%; n = 19), recruitment (7%; n = 9), intervention (7%; n = 9), and network analysis (4%; n = 5). These studies collectively analyzed more than 5 billion tweets primarily by using the Twitter application program interface. Of 38 potential data features describing tweets and Twitter users, 23 were reported in fewer than 4% of the articles. The Twitter-based studies in this review focused on a small subset of data elements including content analysis, geotags, and language. Most studies were published recently (33% in 2015). Public health (23%; n = 31) and infectious disease (20%; n = 28) were the research fields most commonly represented in the included studies. Approximately one third of the studies mentioned ethical board
Twitter and Non-Elites: Interpreting Power Dynamics in the Life Story of the (#)BRCA Twitter Stream.
Vicari, Stefania
2017-09-01
In May 2013 and March 2015, actress Angelina Jolie wrote in the New York Times about her choice to undergo preventive surgery. In her two op-eds, she explained that - as a carrier of the BRCA1 gene mutation - preventive surgery was the best way to lower her heightened risk of developing breast and ovarian cancer. By applying a digital methods approach to BRCA-related tweets from 2013 and 2015, before, during, and after the exposure of Jolie's story, this study maps and interprets Twitter discursive dynamics at two time points of the BRCA Twitter stream. Findings show an evolution in curation and framing dynamics occurring between 2013 and 2015, with individual patient advocates replacing advocacy organizations as top curators of BRCA content and coming to prominence as providers of specialist illness narratives. These results suggest that between 2013 and 2015, Twitter went from functioning primarily as an organization-centered news reporting mechanism, to working as a crowdsourced specialist awareness system. This article advances a twofold contribution. First, it points at Twitter's fluid functionality for an issue public and suggests that by looking at the life story-rather than at a single time point-of an issue-based Twitter stream, we can track the evolution of power roles underlying discursive practices and better interpret the emergence of non-elite actors in the public arena. Second, the study provides evidence of the rise of activist cultures that rely on fluid, non-elite, collective, and individual social media engagement.
Astrophysicists' conversational connections on Twitter.

Because Twitter and other social media are increasingly used for analyses based on altmetrics, this research sought to understand what contexts, affordance use, and social activities influence the tweeting behavior of astrophysicists. Thus, the presented study has been guided by three research questions that consider the influence of astrophysicists' activities (i.e., publishing and tweeting frequency) and of their tweet construction and affordance use (i.e. use of hashtags, language, and emotions) on the conversational connections they have on Twitter. We found that astrophysicists communicate with a variety of user types (e.g. colleagues, science communicators, other researchers, and educators) and that in the ego networks of the astrophysicists clear groups consisting of users with different professional roles can be distinguished. Interestingly, the analysis of noun phrases and hashtags showed that when the astrophysicists address the different groups of very different professional composition they use very similar terminology, but that they do not talk to each other (i.e. mentioning other user names in tweets). The results also showed that in those areas of the ego networks that tweeted more the sentiment of the tweets tended to be closer to neutral, connecting frequent tweeting with information sharing activities rather than conversations or expressing opinions.

The pedagogy of Momus technologies: Facebook, privacy, and online intimacy.
van Manen, Max
2010-08-01
Through cable and wireless connections at home and at work, through Wi-Fi networks and wireless spots in hotels, coffee shops, and town squares, we are indeed connected to each other. But what is the phenomenology of this connection? Technologies of expression such as Facebook, MySpace, Twitter, and other social networking technologies increasingly become like Momus windows of Greek mythology, revealing one's innermost thoughts for all to see. They give access to what used to be personal, secret, and hidden in the lives of its users, especially the young. In this article I explore the pedagogy of Momus effects of social networking technologies in the way they may alter young people's experience of privacy, secrecy, solitude, and intimacy. In addition, I examine the forms of contact afforded by instant messaging and texting on wireless mobile technologies such as the cell phone (and its wireless hybrids) for the way young people are and stay in touch with each other, and how intimacies and inner lives are attended to.

Self-presentation 2.0: narcissism and self-esteem on Facebook.
Mehdizadeh, Soraya
2010-08-01
Online social networking sites have revealed an entirely new method of self-presentation. This cyber social tool provides a new site of analysis to examine personality and identity. The current study examines how narcissism and self-esteem are manifested on the social networking Web site Facebook.com . Self-esteem and narcissistic personality self-reports were collected from 100 Facebook users at York University. Participant Web pages were also coded based on self-promotional content features. Correlation analyses revealed that individuals higher in narcissism and lower in self-esteem were related to greater online activity as well as some self-promotional content. Gender differences were found to influence the type of self-promotional content presented by individual Facebook users. Implications and future research directions of narcissism and self-esteem on social networking Web sites are discussed.
The Effects of Twitter Sentiment on Stock Price Returns

Social media are increasingly reflecting and influencing behavior of other complex systems. In this paper we investigate the relations between a well-known micro-blogging platform Twitter and financial markets. In particular, we consider, in a period of 15 months, the Twitter volume and sentiment about the 30 stock companies that form the Dow Jones Industrial Average (DJIA) index. We find a relatively low Pearson correlation and Granger causality between the corresponding time series over the entire time period. However, we find a significant dependence between the Twitter sentiment and abnormal returns during the peaks of Twitter volume. This is valid not only for the expected Twitter volume peaks (e.g., quarterly announcements), but also for peaks corresponding to less obvious events. We formalize the procedure by adapting the well-known “event study” from economics and finance to the analysis of Twitter data. The procedure allows to automatically identify events as Twitter volume peaks, to compute the prevailing sentiment (positive or negative) expressed in tweets at these peaks, and finally to apply the “event study” methodology to relate them to stock returns. We show that sentiment polarity of Twitter peaks implies the direction of cumulative abnormal returns. The amount of cumulative abnormal returns is relatively low (about 1–2%), but the dependence is statistically significant for several days after the events. PMID:26390434

2017-02-01
Twitter has recently gained popularity in emergency medicine (EM). Opinion leaders on Twitter have significant influence on the conversation and content, yet little is known about these opinion leaders. We aimed to describe a methodology to identify the most influential emergency physicians (EP) on Twitter and present a current list. We analyzed 2,234 English-language EPs on Twitter from a previously published list of Twitter accounts generated by a snowball sampling technique. Using NodeXL software, we performed a network analysis of these EPs and ranked them on three measures of influence: in-degree centrality, eigenvector centrality, and betweenness centrality. We analyzed the top 100 users in each of these three measures of influence and compiled a list of users found in the top 100 in all three measures. Of the 300 total users identified by one of the measures of influence, there were 142 unique users. Of the 142 unique users, 61 users were in the top 100 on all three measures of influence. We identify these 61 users as the most influential EM Twitter users. We both describe a method for identifying the most influential users and provide a list of the 61 most influential EPs on Twitter as of January 1, 2016. This application of network science to the EM Twitter community can guide future research to better understand the networked global community of EM.

Research suggests that Facebooking can be both beneficial and detrimental for users’ psychological well-being. The current study attempts to reconcile these seemingly mixed and inconsistent findings by unpacking the specific effects of Facebooking on users’ online–offline social relationship satisfaction and psychological well-being. Using structural equation modeling, pathways were examined between Facebook intensity, online–offline social relationship satisfaction, perceived social support, social interaction anxiety, and psychological well-being. Personality differences on each of those paths were also assessed. Employing a sample of 342 American university students, results indicated that intensive Facebooking was positively associated with users’ psychological well-being through online social relationship satisfaction, and simultaneously negatively linked to users’ psychological well-being through offline social relationship satisfaction. Multiple group analyses revealed that the linkage between perceived social support and psychological well-being was stronger for introverts than for extraverts. Our findings indicate that the benefits or detriments of Facebooking are contingent upon both personality characteristics and online–offline social contexts. PMID:28197114
Twittering About Research: A Case Study of the World’s First Twitter Poster Competition

2016-01-01
The Royal Society of Chemistry held, to our knowledge, the world’s first Twitter conference at 9am on February 5 th, 2015. The conference was a Twitter-only conference, allowing researchers to upload academic posters as tweets, replacing a physical meeting. This paper reports the details of the event and discusses the outcomes, such as the potential for the use of social media to enhance scientific communication at conferences. In particular, the present work argues that social media outlets such as Twitter broaden audiences, speed up communication, and force clearer and more concise descriptions of a researcher’s work. The benefits of poster presentations are also discussed in terms of potential knowledge exchange and networking. This paper serves as a proof-of-concept approach for improving both the public opinion of the poster, and the enhancement of the poster through an innovative online format that some may feel more comfortable with, compared to face-to-face communication.

Who has Australia's most-followed Twitter accounts in health and medicine?
Chapman, Simon; Freeman, Becky
2015-07-09
Twitter is a social media platform that can be used by people working in health and medicine to distribute information, advocate, debate and network with large numbers of other users. We set out to determine the top 10 Australian Twitter accounts in four categories, ranked by number of Twitter followers. We extracted names with high follower volumes from 'lists' of health and medical Twitter accounts, and then 'crowdsourced' on Twitter for names that were not included on those lists. Individuals tweeting on single-issue topics (especially sugar, nutrition and fitness), health institutions, and people working in the media had higher Twitter followings and lower tweet-to-follower ratios than those tweeting on mixed health topics. Tweeting pictures was nominated by several as a way of attracting retweets. Highly followed Twitter users expressed a variety of benefits of using Twitter.

Social sensing of urban land use based on analysis of Twitter users’ mobility patterns
Soltani, Kiumars; Yin, Junjun; Padmanabhan, Anand; Wang, Shaowen
2017-01-01
A number of recent studies showed that digital footprints around built environments, such as geo-located tweets, are promising data sources for characterizing urban land use. However, challenges for achieving this purpose exist due to the volume and unstructured nature of geo-located social media. Previous studies focused on analyzing Twitter data collectively resulting in coarse resolution maps of urban land use. We argue that the complex spatial structure of a large collection of tweets, when viewed through the lens of individual-level human mobility patterns, can be simplified to a series of key locations for each user, which could be used to characterize urban land use at a higher spatial resolution. Contingent issues that could affect our approach, such as Twitter users’ biases and tendencies at locations where they tweet the most, were systematically investigated using 39 million geo-located Tweets and two independent datasets of the City of Chicago: 1) travel survey and 2) parcel-level land use map. Our results support that the majority of Twitter users show a preferential return, where their digital traces are clustered around a few key locations. However, we did not find a general relation among users between the ranks of locations for an individual—based on the density of tweets—and their land use types. On the contrary, temporal patterns of tweeting at key locations were found to be coherent among the majority of users and significantly associated with land use types of these locations. Furthermore, we used these temporal patterns to classify key locations into generic land use types with an overall classification accuracy of 0.78. The contribution of our research is twofold: a novel approach to resolving land use types at a higher resolution, and in-depth understanding of Twitter users’ location-related and temporal biases, promising to benefit human mobility and urban studies in general.

To pilot public health interventions at women potentially interested in maternity care via campaigns on social media (Twitter), social networks (Facebook), and online search engines (Google Search). Primary data from Twitter, Facebook, and Google Search on users of these platforms in Los Angeles between March and July 2014. Observational study measuring the responses of targeted users of Twitter, Facebook, and Google Search exposed to our sponsored messages soliciting them to start an engagement process by clicking through to a study website containing information on maternity care quality information for the Los Angeles market. Campaigns reached a little more than 140,000 consumers each day across the three platforms, with a little more than 400 engagements each day. Facebook and Google search had broader reach, better engagement rates, and lower costs than Twitter. Costs to reach 1,000 targeted users were approximately in the same range as less well-targeted radio and TV advertisements, while initial engagements-a user clicking through an advertisement-cost less than $1 each. Our results suggest that commercially available online advertising platforms in wide use by other industries could play a role in targeted public health interventions. © Health Research and Educational Trust.

Twitter as a place where people meet to make suicide pacts.
Lee, S Y; Kwon, Y
2018-06-01
To examine how Twitter is used as a place where people seek others to make suicide pacts. This is an exploratory quantitative study. We used Twitter application programming interfaces to collect all Korean tweets containing the term 'suicide pact' between October 16, 2017 and November 30, 2017. A Python program and human coders were employed to further identify tweets that aimed to seek others to make a suicide pact and analyze the content of each tweet. Poisson regression analysis was used to examine the characteristics of the tweets that attracted more replies. During the data collection period comprising 43 days, 1702 tweets posted by 551 users were aimed to find others to make suicide pacts. Many of the tweets contained detailed information such as the name of city, gender and age of the user, preferred contact method, and preferred gender of a partner. The number of replies to a tweet seeking a suicide pact varied according to the types of the information contained in the tweet. The results of this study indicate that Twitter might be an attractive place where people try to meet others to make a suicide pact. Thus, the government should try to prevent cases of suicides caused by suicide pacts made via Twitter. Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd.

Toward Real-Time Infoveillance of Twitter Health Messages.
Colditz, Jason B; Chu, Kar-Hai; Emery, Sherry L; Larkin, Chandler R; James, A Everette; Welling, Joel; Primack, Brian A
2018-06-21
There is growing interest in conducting public health research using data from social media. In particular, Twitter "infoveillance" has demonstrated utility across health contexts. However, rigorous and reproducible methodologies for using Twitter data in public health are not yet well articulated, particularly those related to content analysis, which is a highly popular approach. In 2014, we gathered an interdisciplinary team of health science researchers, computer scientists, and methodologists to begin implementing an open-source framework for real-time infoveillance of Twitter health messages (RITHM). Through this process, we documented common challenges and novel solutions to inform future work in real-time Twitter data collection and subsequent human coding. The RITHM framework allows researchers and practitioners to use well-planned and reproducible processes in retrieving, storing, filtering, subsampling, and formatting data for health topics of interest. Further considerations for human coding of Twitter data include coder selection and training, data representation, codebook development and refinement, and monitoring coding accuracy and productivity. We illustrate methodological considerations through practical examples from formative work related to hookah tobacco smoking, and we reference essential methods literature related to understanding and using Twitter data.

Stellrecht, Elizabeth; Hendrix, Dean
2016-01-01
Twitter is a popular social media platform used by organizations for communication and marketing purposes. Many libraries, including members of the Association of Academic Health Sciences Libraries (AAHSL), have Twitter accounts, but how do these libraries use Twitter to communicate with their constituents and are they using it effectively? This study is a large-scale observational study of Twitter use within AAHSL libraries and reflects on the usage patterns present in the context of social media best practices. This study also aims to expand upon best practices for implementing and maintaining a Twitter account in a health sciences library setting.

Rohingya is an ethnicity in Myanmar. Recently there was a conflict in the area between the Rakhine population and the Myanmar army. Many opinions are pro and contra in addressing this issue. There is a critic, there is a support and there is a neutral. The purpose of this paper is to analyze the world public opinion about the case of Rohingya. The opinion data to be processed is taken from twitter. the reason for using twitter is because twitter has become one of the popular social media and includes the most frequently visited social media. Therefore, it would be a lot of data that can be taken from twitter to be processed in the process of sentiment analysis. The grouping of opinions will be divided into 3 parts of positive, negative and neutral. the method used in grouping is the naïve Bayes method.

Although health policy research should inform policy making, the communication gap between researchers and policy makers limits successful translation. Social media represents a new opportunity to connect researchers and policy makers. Our objective was to assess who Congressional health policy staff follow on a major social media platform. Cross-sectional study. Our study measured Congressional health policy staff's use of Twitter and the types of individuals and organizations they follow. To focus on more influential Twitter accounts, we restricted our sample to those followed by at least 3 individual Congressional staff members. Of the 30,843 accounts followed by the 115 Congressional health policy staff, 1273 were potentially policy-related and followed by 3 or more staff. Of these, few were academically affiliated (2.4%) or explicitly health-related (5.6%) sites; many were general news media sources (50.9%) and political and governmental sources (36.4%). Health-focused accounts were frequently connected to the news media or government rather than academia. Top accounts followed (ie, highest quintile) were most likely to be national news organizations (odds ratio [OR], 5.88; 95% confidence interval [CI], 1.75-19.7) and elected officials (OR, 8.22; 95% CI, 1.75-38.6) compared with advocacy and interest groups. Health-related and academic sources are largely absent from the Twitter conversations with US Congressional health policy staff. Even within social media, traditional and political news media are important information intermediaries that researchers and journals should target to disseminate health policy evidence.

"My YAP Family": Analysis of a Facebook Group for Young Adults Living with HIV.
Gaysynsky, Anna; Romansky-Poulin, Kathryn; Arpadi, Stephen
2015-06-01
Little research exists regarding the use of social networking sites, like Facebook, for improving patient well-being. The aim of this study was to evaluate a private Facebook group established for members of an HIV clinic's young adult program. This study employed directed content analysis to examine the types and frequencies of interactions observable in the 3,838 posts and comments that appeared on the Facebook group page between March 1, 2011 and July 1, 2012. Analysis revealed that a large percentage (41.7 %) of the content was classified as "administrative/engagement in group" and functioned to enhance the operations of the program as a whole. Additionally, positive interactions were frequently observed, especially socializing (24.8 %), banter (20.2 %), and offers of social support (15.1 %). Emotional support was the most frequent type of support requested, while esteem support was the most commonly provided form of support. The results of this study demonstrate that a Facebook group can be a means of providing patients with social support and positive social interaction and can improve services for young adults with HIV.
Is Twitter a forum for disseminating research to health policy makers?
Kapp, Julie M; Hensel, Brian; Schnoring, Kyle T
2015-12-01
Findings from scientific research largely remain inside the scientific community. Research scientists are being encouraged to use social media, and especially Twitter, for dissemination of evidence. The potential for Twitter to narrow the gap on evidence translated into policy presents new opportunities. We explored the innovative question of the feasibility of Twitter as a tool for the scientific community to disseminate to and engage with health policy makers for research impact. We created a list of federal "health policy makers." In December 2014, we identified members using several data sources, then collected and summarized their Twitter usage data. Nearly all health policy makers had Twitter accounts. Their communication volume varied broadly. Policy makers are more likely to push information via Twitter than engage with constituents, although usage varied broadly. Twitter has the potential to aid the scientific community in dissemination of health-related research to health policy makers, after understanding how to effectively (and selectively) use Twitter.

Objective The purpose of this study was to describe adults who use Twitter during a weight loss attempt and to compare the positive and negative social influences they experience from their offline friends, online friends, and family members. Materials and methods Participants (N=100, 80% female, mean age=37.65, SD=8.42) were recruited from Twitter. They completed a brief survey about their experiences discussing their weight loss attempt with their online and offline friends and provided responses to open-ended questions on the benefits and drawbacks of discussing weight on Twitter, Facebook, and weight-specific social networks. Results Participants rated their connections on Twitter and weight loss-specific social networks to be significantly greater sources of positive social influence for their weight loss (F(3)=3.47; p<0.001) and significantly lesser sources of negative social influence (F(3)=40.39 and F(3)=33.68 (both p<0.001)) than their offline friends, family, and Facebook friends. Greater positive social influence from Twitter and Facebook friends was associated with greater weight loss in participants’ most recent weight loss attempt (r=0.30, r=0.32; p<0.01). The most commonly reported benefits of tweeting about weight loss include social support, information, and accountability. The most common drawbacks reported are that interactions were too brief and lacked personal connection. Discussion People who discuss their weight loss on Twitter report more social support and less negativity from their Twitter friends than their Facebook friends and in-person relationships. Conclusions Online social networks should be explored as a tool for connecting patients who lack weight loss social support from their in-person relationships. PMID:24928175

Previous studies have confirmed that Facebook, the leading social networking site among young people, facilitates social connections among college students, but the specific activities and motives that foster social adjustment remain unclear. This study examined associations between patterns of Facebook activity, motives for using Facebook, and late adolescents' social adjustment to the college environment. Anonymous self-report survey data from 193 mostly European American students (M age = 20.32; 54 % female) attending a major Midwestern university indicated that motives and activity patterns were associated directly with social adjustment, but the association between one activity, status updating, and social adjustment also was moderated by the motive of relationship maintenance. Findings provide a more comprehensive portrait of how Facebook use may foster or inhibit social adjustment in college.
Twelve tips for using Twitter as a learning tool in medical education.
Forgie, Sarah Edith; Duff, Jon P; Ross, Shelley
2013-01-01
Twitter is an online social networking service, accessible from any Internet-capable device. While other social networking sites are online confessionals or portfolios of personal current events, Twitter is designed and used as a vehicle to converse and share ideas. For this reason, we believe that Twitter may be the most likely candidate for integrating social networking with medical education. Using current research in medical education, motivation and the use of social media in higher education, we aim to show the ways Twitter may be used as a learning tool in medical education. A literature search of several databases, online sources and blogs was carried out examining the use of Twitter in higher education. We created 12 tips for using Twitter as a learning tool and organized them into: the mechanics of using Twitter, suggestions and evidence for incorporating Twitter into many medical education contexts, and promoting research into the use of Twitter in medical education. Twitter is a relatively new social medium, and its use in higher education is in its infancy. With further research and thoughtful application of media literacy, Twitter is likely to become a useful adjunct for more personalized teaching and learning in medical education.

Objective Opposition to human papillomavirus (HPV) vaccination is common on social media and has the potential to impact vaccine coverage. This study aims to conduct an international comparison of the proportions of tweets about HPV vaccines that express concerns, the types of concerns expressed and the social connections among users posting about HPV vaccines in Australia, Canada and the UK. Design Using a cross-sectional design, an international comparison of English language tweets about HPV vaccines and social connections among Twitter users posting about HPV vaccines between January 2014 and April 2016 was conducted. The Health Belief Model, one of the most widely used theories in health psychology, was used as the basis for coding the types of HPV vaccine concerns expressed on Twitter. Setting The content of tweets and the social connections between users who posted tweets about HPV vaccines from Australia, Canada and the UK. Population 16 789 Twitter users who posted 43 852 tweets about HPV vaccines. Main outcome measures The proportions of tweets expressing concern, the type of concern expressed and the proportions of local and international social connections between users. Results Tweets expressing concerns about HPV vaccines made up 14.9% of tweets in Canada, 19.4% in Australia and 22.6% in the UK. The types of concerns expressed were similar across the three countries, with concerns related to ‘perceived barriers’ being the most common. Users expressing concerns about HPV vaccines in each of the three countries had a relatively high proportion of international followers also expressing concerns. Conclusions The proportions and types of HPV vaccine concerns expressed on Twitter were similar across the three countries. Twitter users who mostly expressed concerns about HPV vaccines were better connected to international users who shared their concerns compared with users who did not express concerns about HPV vaccines.

Twitter is gaining growing popularity as a communication platform and potential tool to influence the public in medical matters. The aim here is to examine whether and how robotic surgeons use Twitter more influentially than other urologists. Robotic surgeons and other urologists that tweeted at the European urology congress were compared by assessing Twitter Follower/Following Ratio, Retweet Rank and Percentile and their Twitter strategies. Robotic surgeons had a significantly higher Twitter Follower/Following Ratio (2.1, 1.4-2.4) and Retweet Rank percentile (92.1%, 90.5-93%) than other urologists (1.2, 0.8-2.1 and 88.9%, 87.3-91.7%, respectively). Robotic surgeons used original tweet content and links more often than other urologists (69.4% vs 53.8%, and 19.8% vs 12.5%, respectively). Robotic surgeons had a higher public influence on Twitter than other urologists and posted original tweets and links in tweets and profiles more frequently. This strategy might optimize Twitter use by healthcare professionals in the future. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Public Response to Obamacare on Twitter.
Davis, Matthew A; Zheng, Kai; Liu, Yang; Levy, Helen
2017-05-26
The Affordable Care Act (ACA), often called "Obamacare," is a controversial law that has been implemented gradually since its enactment in 2010. Polls have consistently shown that public opinion of the ACA is quite negative. The aim of our study was to examine the extent to which Twitter data can be used to measure public opinion of the ACA over time. We prospectively collected a 10% random sample of daily tweets (approximately 52 million since July 2011) using Twitter's streaming application programming interface (API) from July 10, 2011 to July 31, 2015. Using a list of key terms and ACA-specific hashtags, we identified tweets about the ACA and examined the overall volume of tweets about the ACA in relation to key ACA events. We applied standard text sentiment analysis to assign each ACA tweet a measure of positivity or negativity and compared overall sentiment from Twitter with results from the Kaiser Family Foundation health tracking poll. Public opinion on Twitter (measured via sentiment analysis) was slightly more favorable than public opinion measured by the Kaiser poll (approximately 50% vs 40%, respectively) but trends over time in both favorable and unfavorable views were similar in both sources. The Twitter-based measures of opinion as well as the Kaiser poll changed very little over time: correlation coefficients for favorable and unfavorable public opinion were .43 and .37, respectively. However, we found substantial spikes in the volume of ACA-related tweets in response to key events in the law's implementation, such as the first open enrollment period in October 2013 and the Supreme Court decision in June 2012. Twitter may be useful for tracking public opinion of health care reform as it appears to be comparable with conventional polling results. Moreover, in contrast with conventional polling, the overall amount of tweets also provides a potential indication of public interest of a particular issue at any point in time. ©Matthew A Davis, Kai Zheng
Representation of health conditions on Facebook: content analysis and evaluation of user engagement.
Hale, Timothy M; Pathipati, Akhilesh S; Zan, Shiyi; Jethwani, Kamal
2014-08-04
A sizable majority of adult Internet users report looking for health information online. Social networking sites (SNS) like Facebook represent a common place to seek information, but very little is known about the representation and use of health content on SNS. Our goal in this study was to understand the role of SNS in health information seeking. More specifically, we aimed to describe how health conditions are represented on Facebook Pages and how users interact with these different conditions. We used Google Insights to identify the 20 most searched for health conditions on Google and then searched each of the resulting terms on Facebook. We compiled a list of the first 50 Facebook "Pages" results for each health condition. After filtering results to identify pages relevant to our research, we categorized pages into one of seven categories based on the page's primary purpose. We then measured user engagement by evaluating the number of "Likes" for different conditions and types of pages. The search returned 50 pages for 18 of the health conditions, but only 48 pages were found for "anemia" and 5 pages were found for "flu symptoms", yielding a total of 953 pages. A large number of pages (29.4%, 280/953) were irrelevant to the health condition searched. Of the 673 relevant pages, 151 were not in English or originated outside the United States, leaving 522 pages to be coded for content. The most common type of page was marketing/promotion (32.2%, 168/522) followed by information/awareness (20.7%, 108/522), Wikipedia-type pages (15.5%, 81/522), patient support (9.4%, 49/522), and general support (3.6%, 19/522). Health conditions varied greatly by the primary page type. All health conditions had some marketing/promotion pages and this made up 76% (29/38) of pages on acquired immunodeficiency syndrome (AIDS). The largest percentage of general support pages were cancer (19%, 6/32) and stomach (16%, 4/25). For patient support, stroke (67%, 4/6), lupus (33%, 10

This study investigated how Facebook's spiral of silence influences political participation. For doing so, this study focused on the roles of politically expressive activities on Facebook and individuals' levels of partisan strength. An online survey (N = 277) was conducted with Facebook users. Results showed that a perceived hostile opinion climate on Facebook was negatively associated with political expression on Facebook, which, in turn, was positively related with political participation. This indirect relationship was conditioned by the degree of Facebook users' partisan strength. Those with weak or moderate levels of partisan strength were less likely to express their minority views, which led to decrease their political participation in the real world. Such indirect relationship was not the case for those with high levels of partisan strength. Theoretical and political implications of these findings were discussed.
A Linguistic Analysis of Suicide-Related Twitter Posts.
O'Dea, Bridianne; Larsen, Mark E; Batterham, Philip J; Calear, Alison L; Christensen, Helen
2017-09-01
Suicide is a leading cause of death worldwide. Identifying those at risk and delivering timely interventions is challenging. Social media site Twitter is used to express suicidality. Automated linguistic analysis of suicide-related posts may help to differentiate those who require support or intervention from those who do not. This study aims to characterize the linguistic profiles of suicide-related Twitter posts. Using a dataset of suicide-related Twitter posts previously coded for suicide risk by experts, Linguistic Inquiry and Word Count (LIWC) and regression analyses were conducted to determine differences in linguistic profiles. When compared with matched non-suicide-related Twitter posts, strongly concerning suicide-related posts were characterized by a higher word count, increased use of first-person pronouns, and more references to death. When compared with safe-to-ignore suicide-related posts, strongly concerning suicide-related posts were characterized by increased use of first-person pronouns, greater anger, and increased focus on the present. Other differences were found. The predictive validity of the identified features needs further testing before these results can be used for interventional purposes. This study demonstrates that strongly concerning suicide-related Twitter posts have unique linguistic profiles. The examination of Twitter data for the presence of such features may help to validate online risk assessments and determine those in need of further support or intervention.

The social networking site, Facebook, has gained an enormous amount of popularity. In this article, we review the literature on the factors contributing to Facebook use. We propose a model suggesting that Facebook use is motivated by two primary needs: (1) The need to belong and (2) the need for self-presentation. Demographic and cultural factors contribute to the need to belong, whereas neuroticism, narcissism, shyness, self-esteem and self-worth contribute to the need for self presentation. Areas for future research are discussed. PMID:22544987

Recruitment and retention of young adult veteran drinkers using Facebook.
Pedersen, Eric R; Naranjo, Diana; Marshall, Grant N
2017-01-01
The objective of this study was to describe the feasibility of using Facebook as a platform to recruit and retain young adult veteran drinkers into an online-alcohol use intervention study. Facebook's wide accessibility and popularity among the age group that comprises the majority of veterans from the conflicts in Iraq and Afghanistan make it a compelling resource through which research can extend its reach to this otherwise hard-to-reach group. We developed a series of Facebook advertisement campaigns to reach veteran drinkers not specifically searching for alcohol treatment. In doing so, we recruited 793 valid veteran participants in approximately two weeks for an advertising cost of $4.53 per obtained participant. The study sample consisted primarily of male veterans, between 19 and 34 years of age, who were drinking at moderate to heavy levels. Although about half of the sample reported mental health comorbidity, few had received any mental health or substance use treatment in the past year. Facebook appears to be a valuable mechanism through which to recruit young veterans with unmet behavioral health needs, although more specific efforts may be needed to engage certain types of veterans after initial study enrollment.
Leveraging Twitter to Maximize the Radiology Meeting Experience.
Kalia, Vivek; Ortiz, Daniel A; Patel, Amy K; Moriarity, Andrew K; Canon, Cheri L; Duszak, Richard
2018-01-01
Over recent years, social media engagement has proliferated among physicians, health care systems, scientific journals, professional societies, and patients. In radiology, Twitter (Twitter Inc, San Francisco, California) has rapidly become the preferred social media engagement tool and is now an essential activity at many large radiology society meetings. Twitter offers a versatile, albeit simple, platform for anyone interested in engaging with others, regardless of title, stature, or geography. In radiology and other medical specialties, year-after-year increases in Twitter engagement before, during, and after professional society meetings continue with widespread positive feedback. This short-form messaging tool also allows users to connect and interact with high-impact individuals and organizations on an ongoing basis (rather than once a year during large meetings). Through live-polling, Twitter also has the power to gather global opinions on issues highly relevant to radiology's future, such as the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) or breast cancer screening. Also increasingly popular is "live-tweeting" of curated meeting content, which makes information from the meeting accessible to a global audience. Despite the promise of growing professional networks and enabling discussions that cross geographic boundaries, the risks of Twitter use during radiology meetings must be recognized and mitigated. These include posting of unpublished data without consent (eg, slide content captured on camera phones), propagation of misinformation, and copyright infringement. Despite these issues and with an eye towards professionalism, Twitter can nonetheless be used effectively to increase engagement among radiologists, radiology societies, and patients.

Background Facebook, the most popular social network with over one billion daily users, provides rich opportunities for its use in the health domain. Though much of Facebook’s data are not available to outsiders, the company provides a tool for estimating the audience of Facebook advertisements, which includes aggregated information on the demographics and interests, such as weight loss or dieting, of Facebook users. This paper explores the potential uses of Facebook ad audience estimates for eHealth by studying the following: (1) for what type of health conditions prevalence estimates can be obtained via social media and (2) what type of marker interests are useful in obtaining such estimates, which can then be used for recruitment within online health interventions. Objective The objective of this study was to understand the limitations and capabilities of using Facebook ad audience estimates for public health monitoring and as a recruitment tool for eHealth interventions. Methods We use the Facebook Marketing application programming interface to correlate estimated sizes of audiences having health-related interests with public health data. Using several study cases, we identify both potential benefits and challenges in using this tool. Results We find several limitations in using Facebook ad audience estimates, for example, using placebo interest estimates to control for background level of user activity on the platform. Some Facebook interests such as plus-size clothing show encouraging levels of correlation (r=.74) across the 50 US states; however, we also sometimes find substantial correlations with the placebo interests such as r=.68 between interest in Technology and Obesity prevalence. Furthermore, we find demographic-specific peculiarities in the interests on health-related topics. Conclusions Facebook’s advertising platform provides aggregate data for more than 190 million US adults. We show how disease-specific marker interests can be used to model
Tweets and Facebook Posts, the Novelty Techniques in the Creation of Origin-Destination Models

Social media and big data have emerged to be a useful source of information that can be used for planning purposes, particularly transportation planning and trip-distribution studies. Cities in developing countries such as South Africa often struggle with out-dated, unreliable and cumbersome techniques such as traffic counts and household surveys to conduct origin and destination studies. The emergence of ubiquitous crowd sourced data, big data, social media and geolocation based services has shown huge potential in providing useful information for origin and destination studies. Perhaps such information can be utilised to determine the origin and destination of commuters using the Gautrain, a high-speed railway in Gauteng province South Africa. To date little is known about the origins and destinations of Gautrain commuters. Accordingly, this study assesses the viability of using geolocation-based services namely Facebook and Twitter in mapping out the network movements of Gautrain commuters. Explorative Spatial Data Analysis (ESDA), Echo-social and ArcGis software were used to extract social media data, i.e. tweets and Facebook posts as well as to visualize the concentration of Gautrain commuters. The results demonstrate that big data and geolocation based services have the significant potential to predict movement network patterns of commuters and this information can thus, be used to inform and improve transportation planning. Nevertheless use of crowd sourced data and big data has privacy concerns that still need to be addressed.

Facebook and social media networking applications use is ubiquitous across all ages and cultures. Facebook has finally begun to appear in the medical-scientific press. Today's medical literature is focused on concerns of professionalism in young health care practitioners vis-à-vis the lay public as they continuously expose themselves through this online social medium. With over 500 million users, Facebook hosts many of our patients, who are also exposed to the Internet and social media. Nobody so far has considered the opposite issue: that of physician invasion of privacy by "looking-up" a patient on Facebook during clinical practice for purposes of history-taking or diagnostic clues in situations where patients are too ill to provide needed information. We need to consider the ethical implications of privacy invasion in the current era of information technology. We need to acquire and maintain a certain level of "social media competency" to better debate the issues around Facebook and how we integrate on-line content with our patients' histories of present illness (HPI) or past medical histories (if at all). © 2011 by the Society for Academic Emergency Medicine.

The current study explored the motivations of online social network use among a sample of the general population in Taiwan (N=4,346). It investigated how seven different motivations to use Facebook predicted the intensity of Facebook use and content-generation behaviors on Facebook. Results showed that the motivation to use Facebook for posting and viewing status updates was the strongest predictor of Facebook intensity, while the motivation to view and share photographs was the strongest predictor of content-generation behavior on the site. Results are discussed in terms of expanding motivations to use Facebook to the study of social networking sites and other new and social media.

Online social networking services such as Facebook provide a novel medium for the dissemination of public health information by poison control centers in the United States. We performed a cross-sectional study of poison control center Facebook pages to describe and assess the use of this medium. Facebook pages associated with poison control centers were identified during a continuous two-week period from December 24, 2012 to January 7, 2013. Data were extracted from each page, including affiliated poison control center; page duration, measured in years since registration; number of subscribers; number of postings by general toxicological category; and measures of user-generated activity including "likes", "shares", and comments per posting. Among the 56 US poison control centers, 39 Facebook pages were identified, of which 29 were currently active. The total number of active pages has increased by 140% from 2009 to 2013 (average of 25% per year). The total number of all subscribers to active pages was 11,211, ranging from 40 to 2,456 (mean 387, SD 523), equal to 0.006% of all Facebook users in the United States. The number of subscribers per page was associated with page duration, number of postings, and type of postings. The types of toxicological postings were public education (45%), self-promotion (28%), childhood safety (12%), drugs of abuse (8%), environmental poisonings (6%), and general overdoses (1%). Slightly over half of all poison control centers in the United States are supplementing their outreach and education efforts through Facebook. In general, the more active the poison control center on Facebook, the more page followers and follower engagement gained.

This study investigates the role of personality factors as predictors of Facebook usage. Data concerning Facebook usage and personality factors from 654 Facebook users were gathered using a web survey. Using path analysis, the results showed Openness was a predictor of Facebook early adoption, Conscientiousness with sparing use, Extraversion with long sessions and abundant friendships, and Neuroticism with high frequency of sessions. The possible role of Agreeableness in predicting low session frequency and friendships needs further validation.

Facebook and MySpace: complement or substitute for face-to-face interaction?
Kujath, Carlyne L
2011-01-01
Previous studies have claimed that social-networking sites are used as a substitute for face-to-face interaction, resulting in deteriorating relationship quality and decreased intimacy among its users. The present study hypothesized that this type of communication is not a substitute for face-to-face interaction; rather, that it is an extension of communication with face-to-face partners. A survey was administered to examine the use of Facebook and MySpace in this regard among 183 college students. The study confirmed that Facebook and MySpace do act as an extension of face-to-face interaction, but that some users do tend to rely on Facebook and MySpace for interpersonal communication more than face-to-face interaction.
Using twitter in health professional education: a case study.
Gagnon, Kendra
2015-01-01
The vast majority of health care students, providers, and organizations utilize social media to access and share information. However, there is little research exploring integration of social media into health professional education. This case study describes how the social media site Twitter was used in a first-year physical therapy professionalism course to teach, support, and model professional online communication. Twitter was used for discussion and sharing among 36 doctor of physical therapy (DPT) students enrolled in a first-year professionalism course. Participants completed four Twitter assignments. Outcome measures included student surveys of overall social media use, perceptions of Twitter use in the course, Twitter use during the course, and student engagement measured using a subset of questions from the National Survey of Student Engagement (NSSE). During the course, students posted a total of 337 tweets (mean 9.36 tweets/student). Pre- and post-course surveys showed an increase in academic and professional social media use. Perception of Twitter use in the course was generally positive. There was a small increase in mean NSSE score that was not statistically significant. Using Twitter in a physical therapy professionalism course was a positive experience for students and was associated with increased academic and professional social media use. Future studies are needed to determine whether deliberate teaching of social media as a professional technology competency will result in meaningful increases in professional online engagement and improved digital professionalism in health professional students and providers.

In this study, we examine chronic materialism as a possible motive for Facebook usage. We test an explanatory mediation model predicting that materialists use Facebook more frequently, because they compare themselves to others, they objectify and instrumentalize others, and they accumulate friends. For this, we conducted two online surveys ( N 1 = 242, N 2 = 289) assessing demographic variables, Facebook use, social comparison, materialism, objectification and instrumentalization. Results confirm the predicted mediation model. Our findings suggest that Facebook can be used as a means to an end in a way of self-regulatory processes, like satisfying of materialistic goals. The findings are the first evidence for our Social Online Self-regulation Theory (SOS-T), which contains numerous predictions that can be tested in the future.

To assess the emerging use of Twitter by urological journals. A search of the Journal of Citation Reports 2012 was performed to identify urological journals. These journals were then searched on Twitter.com. Each journal website was accessed for links to social media (SoMe). The number of 'tweets', followers and age of profile was determined. To evaluate the content, over a 6-month period (November 2013 to April 2014), all tweets were scrutinised on the journals Twitter profiles. To assess SoMe influence, the Klout score of each journal was also calculated. In all, 33 urological journals were identified. Eight (24.2%) had Twitter profiles. The mean (range) number of tweets and followers was 557 (19-1809) and 1845 (82-3692), respectively. The mean (range) age of the twitter profiles was 952 (314-1758) days with an average 0.88 tweets/day. A Twitter profile was associated with a higher mean impact factor of the journal (mean [sd] 3.588 [3.05] vs 1.78 [0.99], P = 0.013). Over a 6-month period, November 2013 to April 2014, the median (range) number of tweets per profile was 82 (2-415) and the median (range) number of articles linked to tweets was 73 (0-336). Of these 710 articles, 152 were Level 1 evidence-based articles, 101 Level 2, 278 Level 3 and 179 Level 4. The median (range) Klout score was 47 (19-58). The Klout scores of major journals did not exactly mirror their impact factors. SoMe is increasingly becoming an adjunct to traditional teaching methods, due to its convenient and user-friendly platform. Recently, many of the leading urological journals have used Twitter to highlight significant articles of interest to readers. © 2014 The Authors. BJU International © 2014 BJU International.
Mining Twitter Data to Augment NASA GPM Validation

Teng, Bill; Albayrak, Arif; Huffman, George; Vollmer, Bruce; Loeser, Carlee; Acker, Jim
2017-01-01
The Twitter data stream is an important new source of real-time and historical global information for potentially augmenting the validation program of NASA's Global Precipitation Measurement (GPM) mission. There have been other similar uses of Twitter, though mostly related to natural hazards monitoring and management. The validation of satellite precipitation estimates is challenging, because many regions lack data or access to data, especially outside of the U.S. and in remote and developing areas. The time-varying set of "precipitation" tweets can be thought of as an organic network of rain gauges, potentially providing a widespread view of precipitation occurrence. Twitter provides a large source of crowd for crowdsourcing. During a 24-hour period in the middle of the snow storm this past March in the U.S. Northeast, we collected more than 13,000 relevant precipitation tweets with exact geolocation. The overall objective of our project is to determine the extent to which processed tweets can provide additional information that improves the validation of GPM data. Though our current effort focuses on tweets and precipitation, our approach is general and applicable to other social media and other geophysical measurements. Specifically, we have developed an operational infrastructure for processing tweets, in a format suitable for analysis with GPM data; engaged with potential participants, both passive and active, to "enrich" the Twitter stream; and inter-compared "precipitation" tweet data, ground station data, and GPM retrievals. In this presentation, we detail the technical capabilities of our tweet processing infrastructure, including data abstraction, feature extraction, search engine, context-awareness, real-time processing, and high volume (big) data processing; various means for "enriching" the Twitter stream; and results of inter-comparisons. Our project should bring a new kind of visibility to Twitter and engender a new kind of appreciation of the value

Background It has been suggested that some dominant aspects of traditional masculinity are contributing to the high suicide rates among Australian men. We developed a three-episode documentary called Man Up, which explores the complex relationship between masculinity and suicide and encourages men to question socially imposed rules about what it means to be a man and asks them to open up, express difficult emotions, and seek help if and when needed. We ran a three-phase social media campaign alongside the documentary using 5 channels (Twitter, Facebook, Instagram, YouTube, and Tumblr). Objective This study aimed to examine the extent to which the Man Up Twitter campaign influenced the social media conversation about masculinity and suicide. Methods We used Twitter insights data to assess the reach of and engagement with the campaign (using metrics on followers, likes, retweets, and impressions) and to determine the highest and lowest performing tweets in the campaign (using an aggregated performance measure of reactions). We used original content tweets to determine whether the campaign increased the volume of relevant Twitter conversations (aggregating the number of tweets for selected campaign hashtags over time), and we used a subset of these data to gain insight into the main content themes with respect to audience engagement. Results The campaign generated a strong following that was engaged with the content of the campaign; over its whole duration, the campaign earned approximately 5000 likes and 2500 retweets and gained around 1,022,000 impressions. The highest performing tweets posted by the host included video footage and occurred during the most active period of the campaign (around the screening of the documentary). The volume of conversations in relation to commonly used hashtags (#MANUP, #ABCMANUP, #LISTENUP, and #SPEAKUP) grew in direct relation to the campaign activities, achieving strongest growth during the 3 weeks when the documentary was aired

This paper has two objectives. First, it categorizes the Twitter handles tweeted flu related information based on the amount of replies and mentions within the Twitter network. The collected Twitter accounts are categorized as media, health related individuals, organizations, government, individuals with no background with media or medical field, in order to test the relationship between centrality measures of the accounts and their categories. The second objective is to examine the relationship between the importance of the Twitter accounts in the network, centrality measures, and specific characteristics of each account, including the number of tweets and followers as well as the number of accounts followed and liked. Using Twitter search network API, tweets with "flu" keyword were collected and tabulated. Network centralities were calculated with network analysis tool, NodeXL. The collected Twitters accounts were content analyzed and categorized by multiple coders. When the media or organizational Twitter accounts were present in the list of important Twitter accounts, they were highly effective disseminating flu-related information. Also, they were more likely to stay active one year after the data collection period compared to other influential individual accounts. Health campaigns are recommended to focus on recruiting influential Twitter accounts and encouraging them to retweet or mention in order to produce better results in disseminating information. Although some individual social media users were valuable assets in terms of spreading information about flu, media and organization handles were more reliable information distributors. Thus, health information practitioners are advised to design health campaigns better utilizing media and organizations rather than individuals to achieve consistent and efficient campaign outcomes.

Does Twitter trigger bursts in signature collections?

2013-01-01
The quantification of social media impacts on societal and political events is a difficult undertaking. The Japanese Society of Oriental Medicine started a signature-collecting campaign to oppose a medical policy of the Government Revitalization Unit to exclude a traditional Japanese medicine, "Kampo," from the public insurance system. The signature count showed a series of aberrant bursts from November 26 to 29, 2009. In the same interval, the number of messages on Twitter including the keywords "Signature" and "Kampo," increased abruptly. Moreover, the number of messages on an Internet forum that discussed the policy and called for signatures showed a train of spikes. In order to estimate the contributions of social media, we developed a statistical model with state-space modeling framework that distinguishes the contributions of multiple social media in time-series of collected public opinions. We applied the model to the time-series of signature counts of the campaign and quantified contributions of two social media, i.e., Twitter and an Internet forum, by the estimation. We found that a considerable portion (78%) of the signatures was affected from either of the social media throughout the campaign and the Twitter effect (26%) was smaller than the Forum effect (52%) in total, although Twitter probably triggered the initial two bursts of signatures. Comparisons of the estimated profiles of the both effects suggested distinctions between the social media in terms of sustainable impact of messages or tweets. Twitter shows messages on various topics on a time-line; newer messages push out older ones. Twitter may diminish the impact of messages that are tweeted intermittently. The quantification of social media impacts is beneficial to better understand people's tendency and may promote developing strategies to engage public opinions effectively. Our proposed method is a promising tool to explore information hidden in social phenomena.
Engagement of young adult cancer survivors within a Facebook-based physical activity intervention.
Valle, Carmina G; Tate, Deborah F
2017-12-01
Few studies have examined how young adult cancer survivors use online social media. The objective of this study was to characterize Facebook engagement by young adult cancer survivors in the context of a physical activity (PA) intervention program. Young adult cancer survivors participated in one of two Facebook groups as part of a 12-week randomized trial of a PA intervention (FITNET) compared to a self-help comparison (SC) condition. A moderator actively prompted group discussions in the FITNET Facebook group, while social interaction was unprompted in the SC group. We examined factors related to engagement, differences in engagement by group format and types of Facebook posts, and the relationship between Facebook engagement and PA outcomes. There were no group differences in the number of Facebook comments posted over 12 weeks (FITNET, 153 vs. SC, 188 p = 0.85) or the proportion of participants that reported engaging within Facebook group discussions at least 1-2 days/week. The proportion of participants that made any posts decreased over time in both groups. SC participants were more likely than FITNET participants to agree that group discussions caused them to become physically active (p = 0.040) and that group members were supportive (p = 0.028). Participant-initiated posts elicited significantly more comments and likes than moderator-initiated posts. Responses posted on Facebook were significantly associated with light PA at 12 weeks (β = 11.77, t(85) = 1.996, p = 0.049) across groups. Engagement within Facebook groups was variable and may be associated with PA among young adult cancer survivors. Future research should explore how to promote sustained engagement in online social networks. ClinicalTrials.gov identifier: NCT01349153.

Winpenny, Eleanor M; Marteau, Theresa M; Nolte, Ellen
2014-01-01
In 2011, online marketing became the largest marketing channel in the UK, overtaking television for the first time. This study aimed to describe the exposure of children and young adults to alcohol marketing on social media websites in the UK. We used commercially available data on the three most used social media websites among young people in the UK, from December 2010 to May 2011. We analysed by age (6-14 years; 15-24 years) and gender the reach (proportion of internet users who used the site in each month) and impressions (number of individual pages viewed on the site in each month) for Facebook, YouTube and Twitter. We further analysed case studies of five alcohol brands to assess the marketer-generated brand content available on Facebook, YouTube and Twitter in February and March 2012. Facebook was the social media site with the highest reach, with an average monthly reach of 89% of males and 91% of females aged 15-24. YouTube had a similar average monthly reach while Twitter had a considerably lower usage in the age groups studied. All five of the alcohol brands studied maintained a Facebook page, Twitter page and YouTube channel, with varying levels of user engagement. Facebook pages could not be accessed by an under-18 user, but in most cases YouTube content and Twitter content could be accessed by those of all ages. The rise in online marketing of alcohol and the high use of social media websites by young people suggests that this is an area requiring further monitoring and regulation.

Primary school children's communication experiences with Twitter: a case study from Turkey.
Gunuc, Selim; Misirli, Ozge; Odabasi, H Ferhan
2013-06-01
This case study examines the utilization of Twitter as a communication channel among primary school children. This study tries to answer the following questions: "What are the cases for primary school children's use of Twitter for communication?" and "What are primary school children's experiences of utilizing Twitter for communication?" Participants were 7th grade students (17 female, 34 male; age 13 years) studying in a private primary school in Turkey within the 2011-12 academic year. A questionnaire, semi-structured interview, document analysis, and open ended questions were used as data collection tools. The children were invited and encouraged to use Twitter for communication. Whilst participants had some minor difficulties getting accustomed to Twitter, they managed to use Twitter for communication, a conclusion drawn from the children's responses and tweets within the study. However, the majority of children did not consider Twitter as a communication tool, and were observed to quit using Twitter once the study had ended. They found Twitter unproductive and restrictive for communication. Furthermore, Twitter's low popularity among adolescents was also a problem. This study suggests that social networking tools favored by children should be integrated into educational settings in order to maximize instructional benefits for primary school children and adolescents.
[Using Twitter in oncology. Research, continuing education, and advocacy].
De Fiore, Luciano; Ascierto, Paolo
2015-01-01
Traditional mass media coverage has been enhanced by Twitter, an interactive, real-time media, useful in health care, and particularly in oncology. Social media such as Twitter are gaining increasing acceptance as tools for instantaneous scientific dialogue. Professional medical societies such as ASCO and ESMO are using microblogging to expand the reach of scientific communications at and around their scientific meetings. To widen the message and maximize the potential for word-of-mouth marketing using Twitter, organizations (such as AIOM, ASCO or ESMO) and industries need a strategic communications plan to ensure on-going social media conversations. Twitter is a very powerful tool indeed that amplifies the results of scientific meetings, and conference organisers should put in place strategies to capitalise on this. This review demonstrates that cancer patients also share information more and more via Twitter about their disease, including diagnosis, symptoms, and treatments. This information could prove useful to health care providers.
The Current Use of Social Media in Neurosurgery.
Alotaibi, Naif M; Badhiwala, Jetan H; Nassiri, Farshad; Guha, Daipayan; Ibrahim, George M; Shamji, Mohammed F; Lozano, Andres M
2016-04-01
To measure the presence and popularity of neurosurgical departments, journals, and nonprofit organizations on 3 major social networks. A systematic 2-pronged search strategy was used in June 2015 to identify all accounts on Facebook, Twitter, and YouTube that were relevant to neurosurgery. Online search was conducted by 2 independent authors. All accounts were ranked according to their popularity data. Our search yielded 158 social media accounts (86 Facebook, 59 Twitter, and 13 YouTube) of neurosurgical private and academic practice departments. Of the 158 accounts we retrieved, 117 were for private practice centers (74%). Accounts of academic and private departments had a similar median number of "likes" and "followers" on Facebook and Twitter, respectively. Seven neurosurgical journals only had active Facebook and Twitter accounts (of 20 screened journals). When compared with studies of social media in other medical subspecialties, the use of these networks in neurosurgery followed a similar pattern in their presence and popularity. The current study shows different uses of social media platforms and numbers of users of the online neurosurgical community. Content optimization, advanced metrics of user engagement, and their subsequent effects on academic impact remain unanswered queries and require further prospective study.

Medical students' use of Facebook for educational purposes.
Ali, Anam
2016-06-01
Medical students use Facebook to interact with one another both socially and educationally. This study investigates how medical students in a UK medical school use Facebook to support their learning. In particular, it identifies the nature of their educational activities, and details their experiences of using an educational Facebook group. Twenty-four medical students who self-identified as being Facebook users were invited to focus groups to attain a general overview of Facebook use within an educational context. A textual analysis was then conducted on a small group of intercalating medical students who used a self-created Facebook group to supplement their learning. Five of these students participated in semi-structured interviews. Six common themes were generated. These included 'collaborative learning', 'strategic uses for the preparation for assessment', 'sharing experiences and providing support', 'creating and maintaining connections', 'personal planning and practical organization' and 'sharing and evaluating educational resources'. Evidence from this study shows that medical students are using Facebook informally to enhance their learning and undergraduate lives. Facebook has enabled students to create a supportive learning community amongst their peers. Medical educators wishing to capitalize on Facebook, as a platform for formal educational initiatives, should remain cautious of intruding on this peer online learning community.
Evaluating #VetFinals: Can Twitter help students prepare for final examinations?
Kinnison, Tierney; Whiting, Martin; Magnier, Kirsty; Mossop, Liz
2017-04-01
Twitter is increasingly used in education. In this article, Twitter was evaluated for its potential to aid veterinary students in their preparation for final examinations. "#VetFinals" revision sessions were facilitated by experts on a variety of topics. The initiative was evaluated through consideration of potential participants, session content and student experiences. In analysis of nine sessions, 52 students participated from eight veterinary schools. During a session, the facilitator tweeted 66 times on average, primarily asking a general question. Students on average tweeted 84 times, mostly in response to facilitators. They also asked novel questions and responded to fellow students. Focus groups and interviews with 11 students suggested that: sessions are useful for preparation/self-testing to succeed in exams; the facilitator and session style impact on learning; the sessions feel like personalized learning; there are elements of safety and exposure leading to some fear of tweeting; peer-learning promotes competition; a community of learners was formed; Twitter has become a part of normal professional life. Whilst not all students will take part in this type of social media use, many found it beneficial. The importance of the facilitator suggests the need for faculty development.
Facebook use and chronotype: Results of a cross-sectional study.

2015-01-01
Facebook has become the most popular social networking site round the world. In seeking an explanation for this phenomenon, individual differences in circadian functioning seem to be an interesting issue. The main aim of this study was to examine the potential associations between morningness/eveningness and Facebook use (intrusion and intensity). The participants were 663 Facebook users. The Facebook Intrusion Questionnaire, Facebook Intensity Scale and the Composite Scale of Morningness were used. Our results indicate that chronotype is negatively related with Facebook usage. Eveningness people use Facebook intensively and their Facebook use is more intrusive. Moreover, eveningness in combination with young age predicted Facebook intensity.

This research examined how adolescents' internalizing symptoms, such as depression, anxiety, and loneliness, relate to the content of their Facebook communication and the responses they receive from peers on Facebook. Participants ( n = 125, 56 female, age 18) reported on their internalizing symptoms in the summer following 12 th grade, and downloaded an application to their Facebook account that stored the content of all of their Facebook communication to secure, online archive. Two months of participants' status updates and comments and peers' comments were coded for content. Relations between internalizing symptoms and Facebook communication differed for girls and boys. For girls, internalizing symptoms predicted several types of Facebook content: negative affect, somatic complaints and eliciting support. In contrast, internalizing symptoms were not related to boys' Facebook posts. Relations between internalizing symptoms and peers' responses on Facebook also differed by gender. For girls, internalizing symptoms positively predicted receiving more peer comments expressing negative affect, and peer responses offering support. For boys, internalizing symptoms did not predict any of the measured peer responses. These findings suggest that girls prone to internalizing symptoms use Facebook in ways that appear similar to co-rumination, by expressing problems to friends and receive possibly reinforcing feedback in return.

Representation of Health Conditions on Facebook: Content Analysis and Evaluation of User Engagement
Pathipati, Akhilesh S; Zan, Shiyi; Jethwani, Kamal
2014-01-01
Background A sizable majority of adult Internet users report looking for health information online. Social networking sites (SNS) like Facebook represent a common place to seek information, but very little is known about the representation and use of health content on SNS. Objective Our goal in this study was to understand the role of SNS in health information seeking. More specifically, we aimed to describe how health conditions are represented on Facebook Pages and how users interact with these different conditions. Methods We used Google Insights to identify the 20 most searched for health conditions on Google and then searched each of the resulting terms on Facebook. We compiled a list of the first 50 Facebook “Pages” results for each health condition. After filtering results to identify pages relevant to our research, we categorized pages into one of seven categories based on the page’s primary purpose. We then measured user engagement by evaluating the number of “Likes” for different conditions and types of pages. Results The search returned 50 pages for 18 of the health conditions, but only 48 pages were found for “anemia” and 5 pages were found for “flu symptoms”, yielding a total of 953 pages. A large number of pages (29.4%, 280/953) were irrelevant to the health condition searched. Of the 673 relevant pages, 151 were not in English or originated outside the United States, leaving 522 pages to be coded for content. The most common type of page was marketing/promotion (32.2%, 168/522) followed by information/awareness (20.7%, 108/522), Wikipedia-type pages (15.5%, 81/522), patient support (9.4%, 49/522), and general support (3.6%, 19/522). Health conditions varied greatly by the primary page type. All health conditions had some marketing/promotion pages and this made up 76% (29/38) of pages on acquired immunodeficiency syndrome (AIDS). The largest percentage of general support pages were cancer (19%, 6/32) and stomach (16%, 4/25). For
Facebook: The Use of Social Media to Engage Parents in a Preschool Obesity Prevention Curriculum.
Swindle, Taren M; Ward, Wendy L; Whiteside-Mansell, Leanne
2018-01-01
This study investigated the use of Facebook to deliver health-related education materials to augment a preschool classroom-based obesity prevention curriculum. Cross-sectional, mixed methods (descriptive and interviews). Head Start classrooms administered by 2 large agencies (1 rural and 1 urban). Convenience sample of parents in 13 classrooms (cohort 1, 3 classrooms; cohort 2, 10 classrooms). Delivery of nutrition education curriculum content using social media (Facebook). Qualitative interviews assessed barriers and facilitators to Facebook use. Parent views, likes, and comments were measured to reflect parent engagement with Facebook. Content analyses (qualitative data) and descriptive statistics (quantitative data). Family access (views) and interaction (comments and likes) with the posts varied based on type and content of posts. Rural families were more active. Barriers to parental Facebook engagement included a desire to see more posts from classroom teachers, lack of time, and misunderstanding about privacy protections. Facilitators of parental Facebook engagement included perceived utility of the content and social support. Facebook was found to be a feasible platform to provide nutrition education and facilitated varying levels of parental engagement. Lessons learned and implications for prevention and intervention programming are offered. Copyright © 2017 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

The Psychological Benefits of Being Authentic on Facebook.
Grieve, Rachel; Watkinson, Jarrah
2016-07-01
Having others acknowledge and validate one's true self is associated with better psychological health. Existing research indicates that an individual's true self may be more readily expressed on Facebook than in person. This study brought together these two premises by investigating for the first time the psychosocial outcomes associated with communicating one's true self on Facebook. Participants (n = 164) completed a personality assessment once as their true self and once as the self they present on Facebook (Facebook self), as well as measures of social connectedness, subjective well-being, depression, anxiety, and stress. Euclidean distances quantified the difference between one's true self and the Facebook self. Hypotheses received partial support. Better coherence between the true self and the Facebook self was associated with better social connectedness and less stress. Two models provided evidence of mediation effects. Findings highlight that authentic self-presentation on Facebook can be associated with positive psychological outcomes.

There is a growing concern that excessive and uncontrolled use of Facebook not only interferes with performance at school or work but also poses threats to physical and psychological well-being. The present research investigated how two individual difference variables--social anxiety and need for social assurance--affect problematic use of Facebook. Drawing on the basic premises of the social skill model of problematic Internet use, we hypothesized that social anxiety and need for social assurance would be positively correlated with problematic use of Facebook. Furthermore, it was predicted that need for social assurance would moderate the relationship between social anxiety and problematic use. A cross-sectional online survey was conducted with a college student sample in the United States (N=243) to test the proposed hypotheses. Results showed that both social anxiety and need for social assurance had a significant positive association with problematic use of Facebook. More importantly, the data demonstrated that need for social assurance served as a significant moderator of the relationship between social anxiety and problematic Facebook use. The positive association between social anxiety and problematic Facebook use was significant only for Facebook users with medium to high levels of need for social assurance but not for those with a low level of need for social assurance. Theoretical and practical implications of these findings were discussed.

Novel approaches are needed to address elevated tobacco use among people with schizophrenia. This exploratory study examined the frequency, timing, and type of communication about tobacco-related content on Twitter among users who self-identify as having schizophrenia compared with users from the general population. Over a 200-day period from January to July 2016, Twitter users who self-identify as having a schizophrenia spectrum disorder (n = 203) and a randomly selected group of general population control users (n = 173) posted 1,544,122 tweets. Communication frequency did not differ between groups. Tweets containing tobacco-related keywords were extracted. Twitter users with schizophrenia posted significantly more tweets containing any tobacco-related terms (mean = 3.74; SD = 16.3) compared with control users (mean = 0.82; SD = 1.8). A significantly greater proportion of Twitter users with schizophrenia (45%; n = 92) posted tweets containing any tobacco terms compared with control users (30%; n = 52). Schizophrenia users showed significantly greater odds of tweeting about tobacco compared with control users (OR = 1.99; 95% CI 1.29–3.07). These findings suggest that online communication about tobacco may parallel real world trends of elevated tobacco use observed among people with schizophrenia. By showing that Twitter users who self-identify as having schizophrenia discuss tobacco-related content online, popular social media could inform smoking cessation efforts targeting this at-risk group.

While fully online citizen science projects like Galaxy Zoo and Moon Zoo are able to garner participation by tens to hundreds of thousands of people, this success pales next to the number of people who use Facebook. With a population well over half a billion, Facebook is, at the time of this writing, the largest single online community. As an experiment in social science-engagement, we have created Facebook fan pages for Zooniverse science tasks, social-sharing apps for Moon Zoo and Galaxy Zoo, and a novel galaxy-related citizen science project all within Facebook. In this poster we present early analysis on how these engagements attract both old and new users, and how users choose to share and interact through these pages.
Stance and influence of Twitter users regarding the Brexit referendum.

Social media are an important source of information about the political issues, reflecting, as well as influencing, public mood. We present an analysis of Twitter data, collected over 6 weeks before the Brexit referendum, held in the UK in June 2016. We address two questions: what is the relation between the Twitter mood and the referendum outcome, and who were the most influential Twitter users in the pro- and contra-Brexit camps? First, we construct a stance classification model by machine learning methods, and are then able to predict the stance of about one million UK-based Twitter users. The demography of Twitter users is, however, very different from the demography of the voters. By applying a simple age-adjusted mapping to the overall Twitter stance, the results show the prevalence of the pro-Brexit voters, something unexpected by most of the opinion polls. Second, we apply the Hirsch index to estimate the influence, and rank the Twitter users from both camps. We find that the most productive Twitter users are not the most influential, that the pro-Brexit camp was four times more influential, and had considerably larger impact on the campaign than the opponents. Third, we find that the top pro-Brexit communities are considerably more polarized than the contra-Brexit camp. These results show that social media provide a rich resource of data to be exploited, but accumulated knowledge and lessons learned from the opinion polls have to be adapted to the new data sources.
Mirror, mirror on my Facebook wall: effects of exposure to Facebook on self-esteem.
Gonzales, Amy L; Hancock, Jeffrey T
2011-01-01
Contrasting hypotheses were posed to test the effect of Facebook exposure on self-esteem. Objective Self-Awareness (OSA) from social psychology and the Hyperpersonal Model from computer-mediated communication were used to argue that Facebook would either diminish or enhance self-esteem respectively. The results revealed that, in contrast to previous work on OSA, becoming self-aware by viewing one's own Facebook profile enhances self-esteem rather than diminishes it. Participants that updated their profiles and viewed their own profiles during the experiment also reported greater self-esteem, which lends additional support to the Hyperpersonal Model. These findings suggest that selective self-presentation in digital media, which leads to intensified relationship formation, also influences impressions of the self.

Background One of the essential services provided by the US local health departments is informing and educating constituents about health. Communication with constituents about public health issues and health risks is among the standards required of local health departments for accreditation. Past research found that only 61% of local health departments met standards for informing and educating constituents, suggesting a considerable gap between current practices and best practice. Objective Social media platforms, such as Twitter, may aid local health departments in informing and educating their constituents by reaching large numbers of people with real-time messages at relatively low cost. Little is known about the followers of local health departments on Twitter. The aim of this study was to examine characteristics of local health department Twitter followers and the relationship between local health department characteristics and follower characteristics. Methods In 2013, we collected (using NodeXL) and analyzed a sample of 4779 Twitter followers from 59 randomly selected local health departments in the United States with Twitter accounts. We coded each Twitter follower for type (individual, organization), location, health focus, and industry (eg, media, government). Local health department characteristics were adopted from the 2010 National Association of City and County Health Officials Profile Study data. Results Local health department Twitter accounts were followed by more organizations than individual users. Organizations tended to be health-focused, located outside the state from the local health department being followed, and from the education, government, and non-profit sectors. Individuals were likely to be local and not health-focused. Having a public information officer on staff, serving a larger population, and “tweeting” more frequently were associated with having a higher percentage of local followers. Conclusions Social media has the

Opposition to human papillomavirus (HPV) vaccination is common on social media and has the potential to impact vaccine coverage. This study aims to conduct an international comparison of the proportions of tweets about HPV vaccines that express concerns, the types of concerns expressed and the social connections among users posting about HPV vaccines in Australia, Canada and the UK. Using a cross-sectional design, an international comparison of English language tweets about HPV vaccines and social connections among Twitter users posting about HPV vaccines between January 2014 and April 2016 was conducted. The Health Belief Model, one of the most widely used theories in health psychology, was used as the basis for coding the types of HPV vaccine concerns expressed on Twitter. The content of tweets and the social connections between users who posted tweets about HPV vaccines from Australia, Canada and the UK. 16 789 Twitter users who posted 43 852 tweets about HPV vaccines. The proportions of tweets expressing concern, the type of concern expressed and the proportions of local and international social connections between users. Tweets expressing concerns about HPV vaccines made up 14.9% of tweets in Canada, 19.4% in Australia and 22.6% in the UK. The types of concerns expressed were similar across the three countries, with concerns related to 'perceived barriers' being the most common. Users expressing concerns about HPV vaccines in each of the three countries had a relatively high proportion of international followers also expressing concerns. The proportions and types of HPV vaccine concerns expressed on Twitter were similar across the three countries. Twitter users who mostly expressed concerns about HPV vaccines were better connected to international users who shared their concerns compared with users who did not express concerns about HPV vaccines. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Twitter-Augmented Journal Club: Educational Engagement and Experience So Far.
Udani, Ankeet D; Moyse, Daniel; Peery, Charles Andrew; Taekman, Jeffrey M
2016-04-15
Social media is a nascent medical educational technology. The benefits of Twitter include (1) easy adoption; (2) access to experts, peers, and patients across the globe; (3) 24/7 connectivity; (4) creation of virtual, education-based communities using hashtags; and (5) crowdsourcing information using retweets. We report on a novel Twitter-augmented journal club for anesthesia residents: its design, implementation, and impact. Our inaugural anesthesia Twitter-augmented journal club succeeded in engaging the anesthesia community and increasing residents' professional use of Twitter. Notably, our experience suggests that anesthesia residents are willing to use social media for their education.
The interpersonal effects of Facebook reassurance seeking.
Clerkin, Elise M; Smith, April R; Hames, Jennifer L
2013-11-01
Social networking sites like Facebook represent a potentially valuable means for individuals with low self-esteem or interpersonal difficulties to connect with others; however, recent research indicates that individuals who are most in need of social benefits from Facebook may be ineffective in their communication strategies, and thereby sabotage their potential to benefit interpersonally. The current study tested whether reassurance seeking via Facebook negatively influenced self-esteem, and whether this change in self-esteem mediated the relationship between Facebook reassurance seeking and greater thwarted belongingness and perceived burdensomeness. Participants completed measures online at two time-points approximately 24 days apart. Results provided evidence that Facebook reassurance seeking predicted lower levels of self-esteem, which in turn predicted increased feelings that one does not belong and that one is a burden. Key limitations to this study include our use of a predominantly young, female, Caucasian sample, a novel reassurance seeking measure, and only evaluating two time points. These results suggest that Facebook usage has the potential for negative and far-reaching influences on one's interpersonal functioning. Published by Elsevier B.V.

The current study investigates whether and how Facebook increases college-age users' subjective well-being by focusing on the number of Facebook friends and self-presentation strategies (positive vs. honest). A structural equation modeling analysis of cross-sectional survey data of college student Facebook users (N=391) revealed that the number of Facebook friends had a positive association with subjective well-being, but this association was not mediated by perceived social support. Additionally, we found that there was a negative curvilinear (inverted U-shape curve) relationship between Facebook friends and perceived social support. As for self-presentation strategies, whereas positive self-presentation had a direct effect on subjective well-being, honest self-presentation had a significant indirect effect on subjective well-being through perceived social support. Our study suggests that the number of Facebook friends and positive self-presentation may enhance users' subjective well-being, but this portion of happiness may not be grounded in perceived social support. On the other hand, honest self-presentation may enhance happiness rooted in social support provided by Facebook friends. Implications of our findings are discussed in light of affirmation of self-worth, time and effort required for building and maintaining friendships, and the important role played by self-disclosure in signaling one's need for social support.

New parents' Facebook use was examined from a social capital perspective. Surveys regarding Facebook use and parenting satisfaction, parenting self-efficacy, and parenting stress were completed by 154 mothers and 150 fathers as part of a larger study of dual-earner, Mid-western U.S. couples making the transition to parenthood. Results indicated that mothers used Facebook more than fathers, and that mothers perceived an increase in use over the transition. When more of mothers' Facebook friends were family members or relatives, and when fathers reported connecting with more of their Facebook friends outside of Facebook, they reported better parental adjustment. For mothers, however, more frequent visits to Facebook accounts and more frequent content management were each associated with higher levels of parenting stress.

Medical educators in recent years have been using social media for more penetrance to technologically-savvy learners. The utility of using Twitter for curriculum content delivery has not been studied. We sought to determine if participation in a social media-based educational supplement would improve student performance on a test of clinical images at the end of the semester. 116 second-year medical students were enrolled in a lecture-based clinical medicine course, in which images of common clinical exam findings were presented. An additional, optional assessment was performed on Twitter. Each week, a clinical presentation and physical exam image (not covered in course lectures) were distributed via Twitter, and students were invited to guess the exam finding or diagnosis. After the completion of the course, students were asked to participate in a slideshow "quiz" with 24 clinical images, half from lecture and half from Twitter. We conducted a one-way analysis of variance to determine the effect Twitter participation had on total, Twitter-only, and lecture-only scores. Twitter participation data was collected from the end-of-course survey and was defined as submitting answers to the Twitter-only questions "all or most of the time", "about half of the time", and "little or none of the time." We found a significant difference in overall scores (p<0.001) and in Twitter-only scores (p<0.001). There was not enough evidence to conclude a significant difference in lecture-only scores (p=0.124). Students who submitted answers to Twitter "all or most of the time" or "about half the time" had significantly higher overall scores and Twitter-only scores (p<0.001 and p<0.001, respectively) than those students who only submitted answers "little or none of the time." While students retained less information from Twitter than from traditional classroom lecture, some retention was noted. Future research on social media in medical education would benefit from clear control and

A Review of Facebook Research in the Social Sciences.
Wilson, Robert E; Gosling, Samuel D; Graham, Lindsay T
2012-05-01
With over 800 million active users, Facebook is changing the way hundreds of millions of people relate to one another and share information. A rapidly growing body of research has accompanied the meteoric rise of Facebook as social scientists assess the impact of Facebook on social life. In addition, researchers have recognized the utility of Facebook as a novel tool to observe behavior in a naturalistic setting, test hypotheses, and recruit participants. However, research on Facebook emanates from a wide variety of disciplines, with results being published in a broad range of journals and conference proceedings, making it difficult to keep track of various findings. And because Facebook is a relatively recent phenomenon, uncertainty still exists about the most effective ways to do Facebook research. To address these issues, the authors conducted a comprehensive literature search, identifying 412 relevant articles, which were sorted into 5 categories: descriptive analysis of users, motivations for using Facebook, identity presentation, the role of Facebook in social interactions, and privacy and information disclosure. The literature review serves as the foundation from which to assess current findings and offer recommendations to the field for future research on Facebook and online social networks more broadly. © The Author(s) 2012.

Detecting Bots on Russian Political Twitter.
Stukal, Denis; Sanovich, Sergey; Bonneau, Richard; Tucker, Joshua A
2017-12-01
Automated and semiautomated Twitter accounts, bots, have recently gained significant public attention due to their potential interference in the political realm. In this study, we develop a methodology for detecting bots on Twitter using an ensemble of classifiers and apply it to study bot activity within political discussions in the Russian Twittersphere. We focus on the interval from February 2014 to December 2015, an especially consequential period in Russian politics. Among accounts actively Tweeting about Russian politics, we find that on the majority of days, the proportion of Tweets produced by bots exceeds 50%. We reveal bot characteristics that distinguish them from humans in this corpus, and find that the software platform used for Tweeting is among the best predictors of bots. Finally, we find suggestive evidence that one prominent activity that bots were involved in on Russian political Twitter is the spread of news stories and promotion of media who produce them.
Communicating genetics and smoking through social media: are we there yet?

2013-09-09
Social media is a recent source of health information that could disseminate new scientific research, such as the genetics of smoking. The objectives were (1) to evaluate the availability of genetic information about smoking on different social media platforms (ie, YouTube, Facebook, and Twitter) and (2) to assess the type and the content of the information displayed on the social media as well as the profile of people publishing this information. We screened posts on YouTube, Facebook, and Twitter with the terms "smoking" and "genetic" at two time points (September 18, 2012, and May 7, 2013). The first 100 posts were reviewed for each media for the time points. Google was searched during Time 2 as an indicator of available information on the Web and the other social media that discussed genetics and smoking. The source of information, the country of the publisher, characteristics of the posts, and content of the posts were extracted. On YouTube, Facebook, and Twitter, 31, 0, and 84 posts, respectively, were included. Posts were mostly based on smoking-related diseases, referred to scientific publications, and were largely from the United States. From the Google search, most results were scientific databases. Six scientific publications referred to within the Google search were also retrieved on either YouTube or Twitter. Despite the importance of public understanding of smoking and genetics, and the high use of social media, little information on this topic is actually present on social media. Therefore, there is a need to monitor the information that is there and to evaluate the population's understanding of the information related to genetics and smoking that is displayed on social media.

Does Twitter Trigger Bursts in Signature Collections?
Yamaguchi, Rui; Imoto, Seiya; Kami, Masahiro; Watanabe, Kenji; Miyano, Satoru; Yuji, Koichiro
2013-01-01
Introduction The quantification of social media impacts on societal and political events is a difficult undertaking. The Japanese Society of Oriental Medicine started a signature-collecting campaign to oppose a medical policy of the Government Revitalization Unit to exclude a traditional Japanese medicine, “Kampo,” from the public insurance system. The signature count showed a series of aberrant bursts from November 26 to 29, 2009. In the same interval, the number of messages on Twitter including the keywords “Signature” and “Kampo,” increased abruptly. Moreover, the number of messages on an Internet forum that discussed the policy and called for signatures showed a train of spikes. Methods and Findings In order to estimate the contributions of social media, we developed a statistical model with state-space modeling framework that distinguishes the contributions of multiple social media in time-series of collected public opinions. We applied the model to the time-series of signature counts of the campaign and quantified contributions of two social media, i.e., Twitter and an Internet forum, by the estimation. We found that a considerable portion (78%) of the signatures was affected from either of the social media throughout the campaign and the Twitter effect (26%) was smaller than the Forum effect (52%) in total, although Twitter probably triggered the initial two bursts of signatures. Comparisons of the estimated profiles of the both effects suggested distinctions between the social media in terms of sustainable impact of messages or tweets. Twitter shows messages on various topics on a time-line; newer messages push out older ones. Twitter may diminish the impact of messages that are tweeted intermittently. Conclusions The quantification of social media impacts is beneficial to better understand people’s tendency and may promote developing strategies to engage public opinions effectively. Our proposed method is a promising tool to explore
Connected Motherhood: Social Support for Moms and Moms-to-Be on Facebook.
Holtz, Bree; Smock, Andrew; Reyes-Gastelum, David
2015-05-01
Research addressing online social support, especially for new mothers, has typically focused on forums and dedicated Web sites, and not on social networking sites like Facebook. Here we expand on this existing body of work by addressing a Facebook page, Ask the Chicks, themed around questions and answers related to motherhood. Using the uses and gratification lens, we explore motivations for participation as they relate to engagement with the page. Individuals were recruited to participant in an online survey through posts on the Ask the Chicks Facebook page made by the page owner over a 1-week period. To be eligible to complete the survey, participants had to be 18 years old or older, female, and pregnant or have at least one child under the age of 5 years. Analyses of survey data collected from users of the page (n=647) revealed that engagement has a positive relationship with the motives of relaxing entertainment, expressive information sharing, social interaction, and information seeking. Online support groups, and especially Facebook, appear to be a more convenient method than traditional online support groups for people who want to obtain information about certain topics, in this case, about motherhood and raising kids. Having this type of social support tool is important, as social support has been found to reduce levels of stress, which can improve overall health and quality of life. This study provides a better understanding of why people use this type of social support group for questions about parenting.
Exploring brand-name drug mentions on Twitter for pharmacovigilance.
Carbonell, Pablo; Mayer, Miguel A; Bravo, Àlex
2015-01-01
Twitter has been proposed by several studies as a means to track public health trends such as influenza and Ebola outbreaks by analyzing user messages in order to measure different population features and interests. In this work we analyze the number and features of mentions on Twitter of drug brand names in order to explore the potential usefulness of the automated detection of drug side effects and drug-drug interactions on social media platforms such as Twitter. This information can be used for the development of predictive models for drug toxicity, drug-drug interactions or drug resistance. Taking into account the large number of drug brand mentions that we found on Twitter, it is promising as a tool for the detection, understanding and monitoring the way people manage prescribed drugs.

OMG Earthquake! Can Twitter improve earthquake response?
NASA Astrophysics Data System (ADS)

2009-12-01
The U.S. Geological Survey (USGS) is investigating how the social networking site Twitter, a popular service for sending and receiving short, public, text messages, can augment its earthquake response products and the delivery of hazard information. The goal is to gather near real-time, earthquake-related messages (tweets) and provide geo-located earthquake detections and rough maps of the corresponding felt areas. Twitter and other social Internet technologies are providing the general public with anecdotal earthquake hazard information before scientific information has been published from authoritative sources. People local to an event often publish information within seconds via these technologies. In contrast, depending on the location of the earthquake, scientific alerts take between 2 to 20 minutes. Examining the tweets following the March 30, 2009, M4.3 Morgan Hill earthquake shows it is possible (in some cases) to rapidly detect and map the felt area of an earthquake using Twitter responses. Within a minute of the earthquake, the frequency of “earthquake” tweets rose above the background level of less than 1 per hour to about 150 per minute. Using the tweets submitted in the first minute, a rough map of the felt area can be obtained by plotting the tweet locations. Mapping the tweets from the first six minutes shows observations extending from Monterey to Sacramento, similar to the perceived shaking region mapped by the USGS “Did You Feel It” system. The tweets submitted after the earthquake also provided (very) short first-impression narratives from people who experienced the shaking. Accurately assessing the potential and robustness of a Twitter-based system is difficult because only tweets spanning the previous seven days can be searched, making a historical study impossible. We have, however, been archiving tweets for several months, and it is clear that significant limitations do exist. The main drawback is the lack of quantitative information

Recruitment is often a difficult and costly part of any human research study. Social media and other emerging means of mass communication hold promise as means to complement traditional strategies used for recruiting participants because they can reach a large number of people in a short amount of time. With the ability to target a specified audience, paid Facebook advertisements have potential to reach future research participants of a specific demographic. This paper describes the experiences of a randomized controlled trial in Edmonton, Alberta, attempting to recruit healthy pregnant women between 8 and 20 weeks' gestation for participation in a prenatal study.

Background Recruitment is often a difficult and costly part of any human research study. Social media and other emerging means of mass communication hold promise as means to complement traditional strategies used for recruiting participants because they can reach a large number of people in a short amount of time. With the ability to target a specified audience, paid Facebook advertisements have potential to reach future research participants of a specific demographic. This paper describes the experiences of a randomized controlled trial in Edmonton, Alberta, attempting to recruit healthy pregnant women between 8 and 20 weeks’ gestation for participation in a prenatal study. Various traditional recruitment approaches, in addition to paid Facebook advertisements were trialed.

There is a paucity of available strategies to increase visibility and engagement in social media (SM) within the neurosurgical community. The objective of this study was to investigate the possible factors for engagement and reach among SM users in neurosurgery. Data from Facebook and Twitter accounts of our institution were collected. We extracted data on demographics and attributes of our current users, including sex, country, age group, device used, and language. Attributes of SM posts were also collected, including time of post, type and content of post, impressions, and engagements. Nonparametric analyses were conducted to evaluate differences in metrics. Metrics were obtained on 192 Facebook and Twitter posts, published online between October 1, 2013, and March 13, 2016. On both platforms, there was a greater representation of male users relative to female users. Facebook users were predominantly in the 18-34 years age range (83%), with most users being from outside of North America. Conversely, users from Canada and the United States comprised the highest proportion of Twitter users. On both platforms, posts containing photos or videos scored significantly higher in engagements and impressions (P < 0.05). Posts on weekdays and during work hours achieved higher visibility and engagements. Moreover, Facebook posts demonstrated higher SM metrics if they mentioned faculty with more than 16 years' experience (P < 0.05). The current study demonstrates that our SM users predominantly comprise a younger demographic and that content optimization with media materials may lead to higher visibility and engagement. The impact of high SM reach on academic neurosurgical programs remains to be determined. Copyright © 2016 Elsevier Inc. All rights reserved.

Dysfunction of Self-Regulation and Self-Control in Facebook Addiction.
Błachnio, Agata; Przepiorka, Aneta
2016-09-01
Nowadays, Facebook has become one of the most popular communication tools. With its increasing popularity, a new phenomenon connected with extensive use has appeared: namely, Facebook intrusion. The answer to the question of who is prone to become addicted still remains open. This study aimed to explore whether insufficient self-control and self-regulation resources in Facebook users are related to Facebook addiction. The participants in the study were 284 people. The Facebook Intrusion Questionnaire, the Brief Self-Control Scale, the Self-Regulation Scale, Action Control Scale, and the Multitasking Scale were used. We found that dysfunctional self-control system can be related to Facebook addiction. An insufficient self-control and low level of failure-related action orientation are those psychological characteristics that put Facebook users "at-risk" of Facebook addiction. The study reveals a picture showing that those Facebook users who are able to resist an impulse or temptation, are more self-disciplined, and do not focus on negative emotions are less likely to develop Facebook addiction. The obtained findings may serve as a basis for prevention programs for people at risk of Facebook addiction.
Tweeting Supertyphoon Haiyan: Evolving Functions of Twitter during and after a Disaster Event.
David, Clarissa C; Ong, Jonathan Corpus; Legara, Erika Fille T

When disaster events capture global attention users of Twitter form transient interest communities that disseminate information and other messages online. This paper examines content related to Typhoon Haiyan (locally known as Yolanda) as it hit the Philippines and triggered international humanitarian response and media attention. It reveals how Twitter conversations about disasters evolve over time, showing an issue attention cycle on a social media platform. The paper examines different functions of Twitter and the information hubs that drive and sustain conversation about the event. Content analysis shows that the majority of tweets contain information about the typhoon or its damage, and disaster relief activities. There are differences in types of content between the most retweeted messages and posts that are original tweets. Original tweets are more likely to come from ordinary users, who are more likely to tweet emotions, messages of support, and political content compared with official sources and key information hubs that include news organizations, aid organization, and celebrities. Original tweets reveal use of the site beyond information to relief coordination and response.

Multi-class machine classification of suicide-related communication on Twitter.
Burnap, Pete; Colombo, Gualtiero; Amery, Rosie; Hodorog, Andrei; Scourfield, Jonathan
2017-08-01
The World Wide Web, and online social networks in particular, have increased connectivity between people such that information can spread to millions of people in a matter of minutes. This form of online collective contagion has provided many benefits to society, such as providing reassurance and emergency management in the immediate aftermath of natural disasters. However, it also poses a potential risk to vulnerable Web users who receive this information and could subsequently come to harm. One example of this would be the spread of suicidal ideation in online social networks, about which concerns have been raised. In this paper we report the results of a number of machine classifiers built with the aim of classifying text relating to suicide on Twitter. The classifier distinguishes between the more worrying content, such as suicidal ideation, and other suicide-related topics such as reporting of a suicide, memorial, campaigning and support. It also aims to identify flippant references to suicide. We built a set of baseline classifiers using lexical, structural, emotive and psychological features extracted from Twitter posts. We then improved on the baseline classifiers by building an ensemble classifier using the Rotation Forest algorithm and a Maximum Probability voting classification decision method, based on the outcome of base classifiers. This achieved an F-measure of 0.728 overall (for 7 classes, including suicidal ideation) and 0.69 for the suicidal ideation class. We summarise the results by reflecting on the most significant predictive principle components of the suicidal ideation class to provide insight into the language used on Twitter to express suicidal ideation. Finally, we perform a 12-month case study of suicide-related posts where we further evaluate the classification approach - showing a sustained classification performance and providing anonymous insights into the trends and demographic profile of Twitter users posting content of this type.
Building automatic customer complaints filtering application based on Twitter in Bahasa Indonesia

Twitter has become a media to provide communication between a company with its customers. The average number of Twitter active users monthly is 330 million. A lot of companies realize the potential of Twitter to establish good relationship with their customers. Therefore, they usually have one official Twitter account to act as customer care division. In Indonesia, one of the company that utilizes the potential of Twitter to reach their customers is PT Telkom. PT Telkom has an official customer service account (called @TelkomCare) to receive customers’ problem. However, because of this account is open for public, Twitter users might post all kind of messages (not only complaints) to Telkom Care account. This leads to a problem that the Telkom Care account contains not only the customer complaints but also compliment and ordinary message. Furthermore, the complaints should be distributed to relevant division such as “Indihome”, “Telkomsel”, “UseeTV”, and “Telepon” based on the content of the message. This research built the application that automatically filter twitter post messages into several pre-defined categories (based on existing divisions) using Naïve Bayes algorithm. This research is done by collecting Twitter message, data cleaning, data pre-processing, training and testing data, and evaluate the classification result. This research yields 97% accuracy to classify Twitter message into the categories mentioned earlier.

Using Facebook Within a Geriatric Pharmacotherapy Course
2010-01-01
Objective To evaluate using an Internet-based social networking site within an elective geriatric pharmacotherapy course. Design Thirty pharmacy students enrolled in a geriatric pharmacotherapy elective course were invited to join a closed Facebook (Facebook Inc, Palo Alto, CA) group to enhance communication among students and faculty members within the course. Creating a discussion board was the primary activity in the course. Each week, 3 students were assigned to post a healthy aging topic, and other students in the class were expected to post their comments and reactions. The healthy aging topics also were discussed during class. Assessment Students wrote reflections about their experiences using Facebook for the activities within this course. A survey instrument also measured students' opinions about using Facebook for educational purposes. Conclusion Using Facebook allowed students to discuss topics more openly and encouraged classroom discussions of healthy aging topics. PMID:21179256

This study examined an aspect of Facebook disclosure that has as yet gone unexplored: whether a user prefers to share information directly, for example, through status updates, or indirectly, via photos with no caption or relationship status changes without context or explanation. The focus was on the sharing of important positive and negative life events related to romantic relationships, health, and work/school in relation to likelihood of sharing this type of information on Facebook and general attitudes toward privacy. An online survey of 599 adult Facebook users found that when positive life events were shared, users preferred to do so indirectly, whereas negative life events were more likely to be disclosed directly. Privacy shared little association with how information was shared. Implications for understanding the finer nuances of how news is shared on Facebook are discussed.
“Hey Everyone, I’m Drunk.” An Evaluation of Drinking-Related Twitter Chatter
Cavazos-Rehg, Patricia A.; Krauss, Melissa J.; Sowles, Shaina J.; Bierut, Laura J.
2015-01-01
Objective: The promotion of drinking behaviors correlates with increased drinking behaviors and intent to drink, especially when peers are the promotion source. Similarly, online displays of peer drinking behaviors have been described as a potential type of peer pressure that might lead to alcohol misuse when the peers to whom individuals feel attached value such behaviors. Social media messages about drinking behaviors on Twitter (a popular social media platform among young people) are common but understudied. In response, and given that drinking alcohol is a widespread activity among young people, we examined Twitter chatter about drinking. Method: Tweets containing alcohol- or drinking-related keywords were collected from March 13 to April 11, 2014. We assessed a random sample (n = 5,000) of the most influential Tweets for sentiment, theme, and source. Results: Most alcohol-related Tweets reflected a positive sentiment toward alcohol use, with pro-alcohol Tweets outnumbering anti-alcohol Tweets by a factor of more than 10. The most common themes of pro-drinking Tweets included references to frequent or heavy drinking behaviors and wanting/needing/planning to drink alcohol. The most common sources of pro-alcohol Tweets were organic (i.e., noncommercial). Conclusions: Our findings highlight the need for online prevention messages about drinking to counter the strong pro-alcohol presence on Twitter. However, to enhance the impact of anti-drinking messages on Twitter, it may be prudent for such Tweets to be sent by individuals who are widely followed on Twitter and during times when heavy drinking is more likely to occur (i.e., weekends, holidays).

A Descriptive Analysis of the Use of Twitter by Emergency Medicine Residency Programs.
Diller, David; Yarris, Lalena M
2018-02-01
Twitter is increasingly recognized as an instructional tool by the emergency medicine (EM) community. In 2012, the Council of Residency Directors in Emergency Medicine (CORD) recommended that EM residency programs' Twitter accounts be managed solely by faculty. To date, little has been published regarding the patterns of Twitter use by EM residency programs. We analyzed current patterns in Twitter use among EM residency programs with accounts and assessed conformance with CORD recommendations. In this mixed methods study, a 6-question, anonymous survey was distributed via e-mail using SurveyMonkey. In addition, a Twitter-based search was conducted, and the public profiles of EM residency programs' Twitter accounts were analyzed. We calculated descriptive statistics and performed a qualitative analysis on the data. Of 168 Accreditation Council for Graduate Medical Education-accredited EM programs, 88 programs (52%) responded. Of those programs, 58% (51 of 88) reported having a program-level Twitter account. Residents served as content managers for those accounts in the majority of survey respondents (61%, 28 of 46). Most programs did not publicly disclose the identity or position of their Twitter content manager. We found a wide variety of applications for Twitter, with EM programs most frequently using Twitter for educational and promotional purposes. There is significant variability in the numbers of followers for EM programs' Twitter accounts. Applications and usage among EM residency programs are varied, and are frequently not consistent with current CORD recommendations.
Twitter and Non-Elites: Interpreting Power Dynamics in the Life Story of the (#)BRCA Twitter Stream
Vicari, Stefania
2017-01-01
In May 2013 and March 2015, actress Angelina Jolie wrote in the New York Times about her choice to undergo preventive surgery. In her two op-eds, she explained that − as a carrier of the BRCA1 gene mutation − preventive surgery was the best way to lower her heightened risk of developing breast and ovarian cancer. By applying a digital methods approach to BRCA-related tweets from 2013 and 2015, before, during, and after the exposure of Jolie’s story, this study maps and interprets Twitter discursive dynamics at two time points of the BRCA Twitter stream. Findings show an evolution in curation and framing dynamics occurring between 2013 and 2015, with individual patient advocates replacing advocacy organizations as top curators of BRCA content and coming to prominence as providers of specialist illness narratives. These results suggest that between 2013 and 2015, Twitter went from functioning primarily as an organization-centered news reporting mechanism, to working as a crowdsourced specialist awareness system. This article advances a twofold contribution. First, it points at Twitter’s fluid functionality for an issue public and suggests that by looking at the life story—rather than at a single time point—of an issue-based Twitter stream, we can track the evolution of power roles underlying discursive practices and better interpret the emergence of non-elite actors in the public arena. Second, the study provides evidence of the rise of activist cultures that rely on fluid, non-elite, collective, and individual social media engagement. PMID:29278246

Mining Twitter Data Stream to Augment NASA GPM Validation
NASA Astrophysics Data System (ADS)
Teng, W. L.; Albayrak, A.; Huffman, G. J.; Vollmer, B.
2017-12-01
The Twitter data stream is an important new source of real-time and historical global information for potentially augmenting the validation program of NASA's Global Precipitation Measurement (GPM) mission. There have been other similar uses of Twitter, though mostly related to natural hazards monitoring and management. The validation of satellite precipitation estimates is challenging, because many regions lack data or access to data, especially outside of the U.S. and in remote and developing areas. The time-varying set of "precipitation" tweets can be thought of as an organic network of rain gauges, potentially providing a widespread view of precipitation occurrence. Twitter provides a large source of crowd for crowdsourcing. During a 24-hour period in the middle of the snow storm this past March in the U.S. Northeast, we collected more than 13,000 relevant precipitation tweets with exact geolocation. The overall objective of our project is to determine the extent to which processed tweets can provide additional information that improves the validation of GPM data. Though our current effort focuses on tweets and precipitation, our approach is general and applicable to other social media and other geophysical measurements. Specifically, we have developed an operational infrastructure for processing tweets, in a format suitable for analysis with GPM data; engaged with potential participants, both passive and active, to "enrich" the Twitter stream; and inter-compared "precipitation" tweet data, ground station data, and GPM retrievals. In this presentation, we detail the technical capabilities of our tweet processing infrastructure, including data abstraction, feature extraction, search engine, context-awareness, real-time processing, and high volume (big) data processing; various means for "enriching" the Twitter stream; and results of inter-comparisons. Our project should bring a new kind of visibility to Twitter and engender a new kind of appreciation of the value

Novel approaches are needed to address elevated tobacco use among people with schizophrenia. This exploratory study examined the frequency, timing, and type of communication about tobacco-related content on Twitter among users who self-identify as having schizophrenia compared with users from the general population. Over a 200-day period from January to July 2016, Twitter users who self-identify as having a schizophrenia spectrum disorder (n = 203) and a randomly selected group of general population control users (n = 173) posted 1,544,122 tweets. Communication frequency did not differ between groups. Tweets containing tobacco-related keywords were extracted. Twitter users with schizophrenia posted significantly more tweets containing any tobacco-related terms (mean = 3.74; SD = 16.3) compared with control users (mean = 0.82; SD = 1.8). A significantly greater proportion of Twitter users with schizophrenia (45%; n = 92) posted tweets containing any tobacco terms compared with control users (30%; n = 52). Schizophrenia users showed significantly greater odds of tweeting about tobacco compared with control users (OR = 1.99; 95% CI 1.29-3.07). These findings suggest that online communication about tobacco may parallel real world trends of elevated tobacco use observed among people with schizophrenia. By showing that Twitter users who self-identify as having schizophrenia discuss tobacco-related content online, popular social media could inform smoking cessation efforts targeting this at-risk group.

The third wheel: the impact of Twitter use on relationship infidelity and divorce.
Clayton, Russell B
2014-07-01
The purpose of this study was to examine how social networking site (SNS) use, specifically Twitter use, influences negative interpersonal relationship outcomes. This study specifically examined the mediational effect of Twitter-related conflict on the relationship between active Twitter use and negative relationship outcomes, and how this mechanism may be contingent on the length of the romantic relationship. A total of 581 Twitter users aged 18 to 67 years (Mage=29, SDage=8.9) completed an online survey questionnaire. Moderation-mediation regression analyses using bootstrapping methods indicated that Twitter-related conflict mediated the relationship between active Twitter use and negative relationship outcomes. The length of the romantic relationship, however, did not moderate the indirect effect on the relationship between active Twitter use and negative relationship outcomes. The results from this study suggest that active Twitter use leads to greater amounts of Twitter-related conflict among romantic partners, which in turn leads to infidelity, breakup, and divorce. This indirect effect is not contingent on the length of the romantic relationship. The current study adds to the growing body of literature investigating SNS use and romantic relationship outcomes.
#Proana: Pro-Eating Disorder Socialization on Twitter.
Arseniev-Koehler, Alina; Lee, Hedwig; McCormick, Tyler; Moreno, Megan A
2016-06-01
Pro-eating disorder (ED) online movements support engagement with ED lifestyles and are associated with negative health consequences for adolescents with EDs. Twitter is a popular social media site among adolescents that provides a unique setting for Pro-ED content to be publicly exchanged. The purpose of this study was to investigate Pro-ED Twitter profiles' references to EDs and how their social connections (followers) reference EDs. A purposeful sample of 45 Pro-ED profiles was selected from Twitter. Profile information, all tweets, and a random sample of 100 of their followers' profile information were collected for content analysis using the Twitter Application Programming Interface. A codebook based on ED screening guidelines was applied to evaluate ED references. For each Pro-ED profile, proportion of tweets with ED references and proportion of followers with ED references in their own profile were evaluated. In total, our 45 Pro-ED profiles generated 4,245 tweets for analysis. A median of 36.4% of profiles' tweets contained ED references. Pro-ED profiles had a median of 173 followers, and a median of 44.5% of followers had ED references. Pro-ED profiles with more tweets with ED references also tended to have more followers with ED references (β = .37, p < .01). Findings suggest that profiles which self-identify as Pro-ED express disordered eating patterns through tweets and have an audience of followers, many of whom also reference ED in their own profiles. ED socialization on Twitter might provide social support, but in the Pro-ED context this activity might also reinforce an ED identity. Copyright © 2016 The Society for Adolescent Health and Medicine.

Public Response to Obamacare on Twitter
Zheng, Kai; Liu, Yang; Levy, Helen
2017-01-01
Background The Affordable Care Act (ACA), often called “Obamacare,” is a controversial law that has been implemented gradually since its enactment in 2010. Polls have consistently shown that public opinion of the ACA is quite negative. Objective The aim of our study was to examine the extent to which Twitter data can be used to measure public opinion of the ACA over time. Methods We prospectively collected a 10% random sample of daily tweets (approximately 52 million since July 2011) using Twitter’s streaming application programming interface (API) from July 10, 2011 to July 31, 2015. Using a list of key terms and ACA-specific hashtags, we identified tweets about the ACA and examined the overall volume of tweets about the ACA in relation to key ACA events. We applied standard text sentiment analysis to assign each ACA tweet a measure of positivity or negativity and compared overall sentiment from Twitter with results from the Kaiser Family Foundation health tracking poll. Results Public opinion on Twitter (measured via sentiment analysis) was slightly more favorable than public opinion measured by the Kaiser poll (approximately 50% vs 40%, respectively) but trends over time in both favorable and unfavorable views were similar in both sources. The Twitter-based measures of opinion as well as the Kaiser poll changed very little over time: correlation coefficients for favorable and unfavorable public opinion were .43 and .37, respectively. However, we found substantial spikes in the volume of ACA-related tweets in response to key events in the law’s implementation, such as the first open enrollment period in October 2013 and the Supreme Court decision in June 2012. Conclusions Twitter may be useful for tracking public opinion of health care reform as it appears to be comparable with conventional polling results. Moreover, in contrast with conventional polling, the overall amount of tweets also provides a potential indication of public interest of a particular
Using social media to monitor mental health discussions - evidence from Twitter.
McClellan, Chandler; Ali, Mir M; Mutter, Ryan; Kroutil, Larry; Landwehr, Justin
2017-05-01
Given the public health importance of communicating about mental illness and the growing use of social media to convey information, our goal was to develop an empirical model to identify periods of heightened interest in mental health topics on Twitter. We collected data on 176 million tweets from 2011 to 2014 with content related to depression or suicide. Using an autoregressive integrated moving average (ARIMA) data analysis, we identified deviations from predicted trends in communication about depression and suicide. Two types of heightened Twitter activity regarding depression or suicide were identified in 2014: expected increases in response to planned behavioral health events, and unexpected increases in response to unanticipated events. Tweet volume following expected increases went back to the predicted level more rapidly than the volume following unexpected events. Although ARIMA models have been used extensively in other fields, they have not been used widely in public health. Our findings indicate that our ARIMA model is valid for identifying periods of heightened activity on Twitter related to behavioral health. The model offers an objective and empirically based measure to identify periods of greater interest for timing the dissemination of credible information related to mental health. Spikes in tweet volume following a behavioral health event often last for less than 2 days. Individuals and organizations that want to disseminate behavioral health messages on Twitter in response to heightened periods of interest need to take this limited time frame into account.

Although the relationship between depression and "offline" social support is well established, numerous questions surround the relationship between "online" social support and depression. We explored this issue by examining the social support dynamics that characterize the way individuals with varying levels of depression (Study 1) and SCID-diagnosed clinically depressed and non-depressed individuals (Study 2) interact with Facebook, the world's largest online social network. Using a novel methodology, we examined how disclosing positive or negative information on Facebook influences the amount of social support depressed individuals (a) actually receive (based on actual social support transactions recorded on Facebook walls) and (b) think they receive (based on subjective assessments) from their Facebook network. Contrary to prior research indicating that depression correlates with less actual social support from "offline" networks, across both studies depression was positively correlated with social support from Facebook networks when participants disclosed negative information (p=.02 in Study 1 and p=.06 in Study 2). Yet, depression was negatively correlated with how much social support participants thought they received from their Facebook networks (p=.005 in Study 1 and p=.001 in Study 2). The sample size was relatively small in Study 2, reflecting difficulties of recruiting individuals with Major Depressive Disorder. These results demonstrate that an asymmetry characterizes the relationship between depression and different types of Facebook social support and further identify perceptions of Facebook social support as a potential intervention target.

Alcohol References on Undergraduate Males’ Facebook Profiles
Egan, Katie G.; Moreno, Megan A.
2011-01-01
Perceived peer alcohol use is a predictor of consumption in college males; frequent references to alcohol on Facebook may encourage alcohol consumption. Content analysis of college males’ Facebook profiles identified references to alcohol. The average age of 225 identified profiles was 19.9 years. Alcohol references were present on 85.3% of the profiles; the prevalence of alcohol was similar across each undergraduate grade. The average number of alcohol references per profile was 8.5 but increased with undergraduate year (p = .003; confidence interval = 1.5, 7.5). Students who were of legal drinking age referenced alcohol 4.5 times more than underage students, and an increase in number of Facebook friends was associated with an increase in displayed alcohol references (p < .001; confidence interval = 0.009, 0.02). Facebook is widely used in the college population; widespread alcohol displays on Facebook may influence social norms and cause increases in male college students’ alcohol use. PMID:21406490

It has been suggested that some dominant aspects of traditional masculinity are contributing to the high suicide rates among Australian men. We developed a three-episode documentary called Man Up, which explores the complex relationship between masculinity and suicide and encourages men to question socially imposed rules about what it means to be a man and asks them to open up, express difficult emotions, and seek help if and when needed. We ran a three-phase social media campaign alongside the documentary using 5 channels (Twitter, Facebook, Instagram, YouTube, and Tumblr). This study aimed to examine the extent to which the Man Up Twitter campaign influenced the social media conversation about masculinity and suicide. We used Twitter insights data to assess the reach of and engagement with the campaign (using metrics on followers, likes, retweets, and impressions) and to determine the highest and lowest performing tweets in the campaign (using an aggregated performance measure of reactions). We used original content tweets to determine whether the campaign increased the volume of relevant Twitter conversations (aggregating the number of tweets for selected campaign hashtags over time), and we used a subset of these data to gain insight into the main content themes with respect to audience engagement. The campaign generated a strong following that was engaged with the content of the campaign; over its whole duration, the campaign earned approximately 5000 likes and 2500 retweets and gained around 1,022,000 impressions. The highest performing tweets posted by the host included video footage and occurred during the most active period of the campaign (around the screening of the documentary). The volume of conversations in relation to commonly used hashtags (#MANUP, #ABCMANUP, #LISTENUP, and #SPEAKUP) grew in direct relation to the campaign activities, achieving strongest growth during the 3 weeks when the documentary was aired. Strongest engagement was found with

Cheating, breakup, and divorce: is Facebook use to blame?
Clayton, Russell B; Nagurney, Alexander; Smith, Jessica R
2013-10-01
The purpose of the present study was to investigate the relationship between using the social networking site known as Facebook and negative interpersonal relationship outcomes. A survey of 205 Facebook users aged 18-82 was conducted using a 16-question online survey to examine whether high levels of Facebook use predicted negative relationship outcomes (breakup/divorce, emotional cheating, and physical cheating). It was hypothesized that those with higher levels of Facebook use would demonstrate more negative relationship outcomes than those with lower use. The study then examined whether these relationships were mediated by Facebook-related conflict. Furthermore, the researchers examined length of relationship as a moderator variable in the aforementioned model. The results indicate that a high level of Facebook usage is associated with negative relationship outcomes, and that these relationships are indeed mediated by Facebook-related conflict. This series of relationships only holds for those who are, or have been, in relatively newer relationships of 3 years or less. The current study adds to the growing body of literature investigating Internet use and relationship outcomes, and may be a precursor to further research investigating whether Facebook use attributes to the divorce rate, emotional cheating, and physical cheating.

An Academic Healthcare Twitter Account: The Mayo Clinic Experience.
Widmer, R Jay; Engler, Nicole B; Geske, Jeffrey B; Klarich, Kyle W; Timimi, Farris K
2016-06-01
With more than 300 million monthly active users, Twitter is a powerful social media tool in healthcare, yet the characterization of an academic healthcare Twitter account remains poor to date. We assessed basic gender and geographic data on the account's "followers," as well as categorization of each tweet based on content type. We analyzed the impressions, engagements, retweets, favorites, replies, hashtag clicks, and detail expansions using both Sprinklr and Twitter Analytics. Over a period of 12 months, the account amassed 1,235 followers, with 54 percent being male and 68 percent residing in the United States. Of the 1,635 tweets sent out over the life of the account, we report more than 382,464 impressions, 6,023 engagements, 1,255 retweets, 776 favorites, and 1,654 embedded media clicks in this period. When broken down by tweet category, publication tweets garnered the highest engagement with an estimated mean number of clicks per tweet of 8.2 ± 81.9. Original content had higher total engagement per tweet than retweeted material (2.8 ± 9.2 vs. 0.2 ± 0.9 engagements per tweet; p < 0.0001). Tweets regarding internal, national, and continuing medical education events had similar engagement. Herein is the first publication within the medical literature describing a "case series" of cardiovascular tweets over 12 months. We highlight a rapidly emerging group of interactive followers, a successful means by which to disseminate and engage in breaking topics throughout the cardiovascular field, and the importance of combining physician-led knowledge with intermittent marketing messages.
Recruiting for addiction research via Facebook.
Thornton, Louise K; Harris, Keith; Baker, Amanda L; Johnson, Martin; Kay-Lambkin, Frances J
2016-07-01
This study aimed to examine the feasibility of recruiting participants to addiction research via Facebook. Participants were recruited via an advertisement on Facebook, a local research register and university psychology courses. Participants completed a self-report survey regarding substance use, history of mental health issues and current psychological distress. The 524 participants recruited via Facebook cost $1.86 per participant; and 418 participants were recruited via more traditional methods. There were significantly fewer women in the Facebook sample compared with the non-Facebook sample (χ(2) = 196.61, P < 0.001), but no differences on age. Significantly more Facebook participants reported current use of tobacco (women: Facebook = 57%, non-Facebook = 21%, χ(2) = 39.71, P < 0.001; men: Facebook = 62%, non-Facebook = 21%, χ(2) = 32.429, P < 0.001) and cannabis (women: Facebook = 26%, non-Facebook = 7%, χ(2) = 14.364, P < 0.001; men: Facebook = 46%, non-Facebook = 24%, χ(2) = 6.765, P < 0.01). They also reported significantly more harmful use of tobacco [women: F degrees of freedom (d.f.) = 6.07, P < 0.05; men: F(d.f.) = 9.03, P < 0.01] and cannabis [women: F(d.f.) = 11.00, P < 0.01; men: F(d.f.) = 6.40, P < 0.05]. The Facebook sample contained a higher percentage of high-severity cannabis users (women: Facebook = 24%, non-Facebook = 4%, χ(2) = 18.12, P < 0.001; men: Facebook = 43%, non-Facebook = 16%, χ(2) = 10.00, P < 0.01) and reported significantly more severe depressive symptoms [women: F(d.f.) = 26.38, P < 0.001; men: F(d.f.) = 7.44, P < 0.05]. Through Facebook, we were able to capture a greater proportion of people with high-severity substance use and mental health issues and were able to capture a greater and more severe range of substance use behaviours. This suggests social networking
Characterizing JUUL-related posts on Twitter.
Allem, Jon-Patrick; Dharmapuri, Likhit; Unger, Jennifer B; Cruz, Tess Boley
2018-06-23
As vaping rapidly becomes more prevalent, social media data can be harnessed to capture individuals' discussions of e-cigarette products quickly. The JUUL vaporizer is the latest advancement in e-cigarette technology, which delivers nicotine to the user from a device that is the size and shape of a thumb drive. Despite JUUL's growing popularity, little research has been conducted on JUUL. Here we utilized Twitter data to determine the public's early experiences with JUUL describing topics of posts. Twitter posts containing the term "JUUL" were obtained for 1 April 2107 to 14 December 2017. Text classifiers were used to identify topics in posts (n = 81,689). The most prevalent topic wasPerson Tagging (use of @username to tag someone in a post) at 20.48% followed by Pods (mentions of JUUL's refill cartridge) at 14.72% and Buying (mentions of purchases) at 10.49%. The topic School (posts indicative of using JUUL or seeing someone use JUUL while at elementary, middle, or high school) comprised 3.66% of posts. The topic of Quit Smoking was rare at 0.29%. Data from social media may be used to extend the surveillance of newly introduced vaping products. Findings suggest Twitter users are bonding around, and inquiring about, JUUL on social media. JUUL's discreetness may facilitate its use in places where vaping is prohibited. Educators may be in need of training on how to identify JUUL in the classroom. Despite JUUL's branding as a smoking alternative, very few Twitter users mentioned smoking cessation with JUUL. Copyright © 2018 Elsevier B.V. All rights reserved.

Community water fluoridation on the Internet and social media.
Mertz, Aaron; Allukian, Myron
2014-01-01
In the United States, 95 percent of teens and 85 percent of adults use the Internet. Two social media outlets, Facebook and Twitter, reach more than 150 billion users. This study describes anti-fluoridation activity and dominance on the Internet and social media, both of which are community water fluoridation (CWF) information sources. Monthly website traffic to major fluoridation websites was determined from June 2011 to May 2012. Facebook, Twitter, and YouTube fluoridation activity was categorized as "proCWF" or "anti-CWF." Twitter's anti-CWF tweets were further subcategorized by the argument used against CWF. Anti-CWF website traffic was found to exceed proCWF activity five- to sixty-fold. Searching "fluoride" and "fluoridation" on Facebook resulted in 88 to 100 percent anti-CWF groups and pages; "fluoridation" on Twitter and YouTube resulted in 64 percent anti-CWF tweets and 99 percent anti-CWF videos, respectively. "Cancer, " "useless, " and "poisonous" were the three major arguments used against fluoridation. Anti-fluoridation information significantly dominates the Internet and social media. Thousands of people are being misinformed daily about the safety, health, and economic benefits of fluoridation.
Characterizing the Followers and Tweets of a Marijuana-Focused Twitter Handle
Krauss, Melissa; Grucza, Richard; Bierut, Laura
2014-01-01
Background Twitter is a popular social media forum for sharing personal experiences, interests, and opinions. An improved understanding of the discourse on Twitter that encourages marijuana use can be helpful for tailoring and targeting online and offline prevention messages. Objectives The intent of the study was to assess the content of “tweets” and the demographics of followers of a popular pro-marijuana Twitter handle (@stillblazingtho). Methods We assessed the sentiment and content of tweets (sent from May 1 to December 31, 2013), as well as the demographics of consumers that follow a popular pro-marijuana Twitter handle (approximately 1,000,000 followers) using Twitter analytics from Demographics Pro. This analytics company estimates demographic characteristics based on Twitter behavior/usage, relying on multiple data signals from networks, consumption, and language and requires confidence of 95% or above to make an estimate of a single demographic characteristic. Results A total of 2590 tweets were sent from @stillblazingtho during the 8-month period and 305 (11.78%) replies to another Twitter user were excluded for qualitative analysis. Of the remaining 2285 tweets, 1875 (82.06%) were positive about marijuana, 403 (17.64%) were neutral, and 7 (0.31%) appeared negative about marijuana. Approximately 1101 (58.72%) of the positive marijuana tweets were perceived as jokes or humorous, 340 (18.13%) implied that marijuana helps you to feel good or relax, 294 (15.68%) mentioned routine, frequent, or heavy use, 193 (10.29%) mentioned blunts, marijuana edibles, or paraphernalia (eg, bongs, vaporizers), and 186 (9.92%) mentioned other risky health behaviors (eg, tobacco, alcohol, other drugs, sex). The majority (699,103/959,143; 72.89%) of @stillblazingtho followers were 19 years old or younger. Among people ages 17 to 19 years, @stillblazingtho was in the top 10% of all Twitter handles followed. More followers of @stillblazingtho in the United States were

Tweeting and Treating: How Hospitals Use Twitter to Improve Care.
Gomes, Christian; Coustasse, Alberto
2015-01-01
Hospitals that have adopted Twitter primarily use it to share organizational news, provide general health care information, advertise upcoming community events, and foster networking. The purpose of this study was to explore the benefits that Twitter utilization has had in improving quality of care, access to care, patient satisfaction, and community footprint while assessing the barriers to its implementation. The methodology used was a qualitative study with a semistructured interview combined with a literature review, which followed the basic principles of a systematic review. The utilization of Twitter by hospitals suggest that it leads to savings of resources, enhanced employee and patient communication, and expanded patient reach in the community. Savings opportunities are generated by preventing unnecessary office visits, producing billable patient encounters, and eliminating high recruiting costs. Communication is enhanced using Twitter by sharing organizational content, news, and health promotions and can be also a useful tool during crises. The utilization of Twitter in the hospital setting has been more beneficial than detrimental in its ability to generate opportunities for cost savings, recruiting, communication with employees and patients, and community reach.
Facebook addiction: a reply to Griffiths (2012).
Andreassen, Cecilie Schou; Pallesen, Ståle
2013-12-01
Our recent paper about a new Facebook addiction scale has stimulated an interesting and very welcome debate among researchers concerning the assessment of excessive use of social networking sites. The critique put forward by Griffiths (2012) is mainly built on the conception of "Facebook" as too narrow of a concept, and that assessment of addiction to social network sites in general would be more appropriate. We argue that the concept of "social network site" is not more specific than "Facebook," so "Facebook addiction" rather than "social network addiction" is defensible. We acknowledge that more research in this area is needed and point specifically to new and important directions for future research that can shed light on the mechanism of addiction to social network sites.
21st Century Connections: Making Sense of Social Media Tools
NASA Technical Reports Server (NTRS)
Fujiech, Maura C.
2010-01-01
Twitter? Blog? Facebook? In an environment of complex project teams and demanding timelines, you may wonder whether any of these new-fangled social media tools that are in the news will help you and your team do a better job delivering project results. What in the world is Facebook and why would I ever want to use it? What does a blog have to do with a NASA project? Aside from my teenager, who cares about Twitter? This introduction to social media is a great way to get your feet wet with some of these new terms and tools. For example, we'll talk about what the difference is between a blog and Facebook. We'll look at some examples of NASA projects that benefit from using blogs, Facebook or Twitter. Most importantly, we'll spend some time talking about how a small or medium-sized project might evaluate whether to use one, many or none of these new ideas. Although there are many commercial tools available and in use across the agency, this talk emphasizes NASA-sponsored tools that are freely available within the Agency.
The many modes of Twitter: developing and maintaining a professional identity on Twitter
NASA Astrophysics Data System (ADS)
Rowan, C. J.
2012-12-01
Describing the potential benefits of using Twitter (or similar social networks such as Google+) is complicated by the fact that it is a tool that can be used in a variety of different ways. Usage of Twitter is a mixture of consumption of links and news from other users and organisations, sharing information (e.g. recently published papers) yourself, and interaction with other users; the precise mixture will vary depending on what a person tweets and who they chose to follow, making every user's experience somewhat unique. In addition to the more commonly cited benefits in the area of scientific outreach, all of these usage modes have potential professional benefits for a scientist, allowing them to keep up to date with the latest developments in their field, and to establish and maintain connections with other scientists. Any or all of these are possible goals for your social media presence and will shape how you use services like Twitter. For a passive real-time news service, you just need to follow the right people and organisations; building an online community requires seeking out like-minded people and regularly interacting with them; true outreach requires building an audience through a long-term commitment to adding value through sharing information and participating in discussions. With respect to your professional identity, the public and relatively informal nature of social networks means that it is important to consider, and set defined limits, on how much of yourself and your opinions you are comfortable sharing. On Twitter, retweets allow something you say to reach many people who do not even follow you, and if you use your real name then your profile may be easily findable on a search engine. On most social networks, it is impossible to totally control your experience as it depends largely on how other users interact with you. Whilst it is useful to consider what you want to get out of your use of social media when you begin, and develop a strategy
Identifying Twitter influencer profiles for health promotion in Saudi Arabia.
Albalawi, Yousef; Sixsmith, Jane
2017-06-01
New media platforms, such as Twitter, provide the ideal opportunity to positively influence the health of large audiences. Saudi Arabia has one of the highest number of Twitter users of any country, some of whom are very influential in setting agendas and contributing to the dissemination of ideas. Those opinion leaders, both individuals and organizations, influential in the new media environment have the potential to raise awareness of health issues, advocate for health and potentially instigate change at a social level. To realize the potential of the new media platforms for public health, the function of opinion leaders is key. This study aims to identify and profile the most influential Twitter accounts in Saudi Arabia. Multiple measures, including: number of followers and four influence scores, were used to evaluate Twitter accounts. The data were then filtered and analysed using ratio and percentage calculations to identify the most influential users. In total, 99 Saudi Twitter accounts were classified, resulting in the identification of 25 religious men/women, 16 traditional media, 14 sports related, 10 new media, 6 political, 6 company and 4 health accounts. The methods used to identify the key influential Saudi accounts can be applied to inform profile development of Twitter users in other countries. © The Author 2015.

Facebook use among early-career veterinarians in Ontario, Canada (March to May 2010).
Weijs, Cynthia A; Coe, Jason B; Christofides, Emily; Muise, Amy; Desmarais, Serge
2013-04-15
To explore the nature and content of information publicly posted to Facebook by early-career veterinarians. Cross-sectional descriptive study. Sample-352 early-career veterinarians. Publicly accessible Facebook profiles were searched online from March to May 2010 for profiles of early-career veterinarians (graduates from 2004 through 2009) registered with the College of Veterinarians of Ontario, Canada. The content of veterinarians' Facebook profiles was evaluated and then categorized as low, medium, or high exposure in terms of the information a veterinarian had publicly posted to Facebook. Through the use of content analysis, high-exposure profiles were further analyzed for publicly posted information that may have posed risks to an individual's or the profession's public image. Facebook profiles for 352 of 494 (71%) registered early-career veterinarians were located. One-quarter (25%) of profiles were categorized as low exposure (ie, high privacy), over half (54%) as medium exposure (i.e., medium privacy), and 21% as high exposure (i.e., low privacy). Content analysis of the high-exposure profiles identified publicly posted information that may pose risks to an individual's or the profession's reputation, including breaches of client confidentiality, evidence of substance abuse, and demeaning comments toward others. Almost a quarter of veterinarians' Facebook profiles viewed in the present study contained publicly available content of a questionable nature that could pose a risk to the reputation of the individual, his or her practice, or the veterinary profession. The increased use of Facebook and all types of social media points to the need for raised awareness by veterinarians of all ages of how to manage one's personal and professional identities online to minimize reputation risks for individuals and their practices and to protect the reputation and integrity of the veterinary profession.
Facebook Use and Disordered Eating in College-Aged Women.
Walker, Morgan; Thornton, Laura; De Choudhury, Munmun; Teevan, Jaime; Bulik, Cynthia M; Levinson, Cheri A; Zerwas, Stephanie
2015-08-01
Disordered eating behavior-dieting, laxative use, fasting, binge eating-is common in college-aged women (11%-20%). A documented increase in the number of young women experiencing eating psychopathology has been blamed on the rise of engagement with social media sites such as Facebook. We predicted that college-aged women's Facebook intensity (e.g., the amount of time spent on Facebook, number of Facebook friends, and integration of Facebook into daily life), online physical appearance comparison (i.e., comparing one's appearance to others' on social media), and online "fat talk" (i.e., talking negatively about one's body) would be positively associated with their disordered eating behavior. In an online survey, 128 college-aged women (81.3% Caucasian, 6.7% Asian, 9.0% African-American, and 3.0% Other) completed items, which measured their disordered eating, Facebook intensity, online physical appearance comparison, online fat talk, body mass index, depression, anxiety, perfectionism, impulsivity, and self-efficacy. In regression analyses, Facebook intensity, online physical appearance comparison, and online fat talk were significantly and uniquely associated with disordered eating and explained a large percentage of the variance in disordered eating (60%) in conjunction with covariates. However, greater Facebook intensity was associated with decreased disordered eating behavior, whereas both online physical appearance comparison and online fat talk were associated with greater disordered eating. College-aged women who endorsed greater Facebook intensity were less likely to struggle with disordered eating when online physical appearance comparison was accounted for statistically. Facebook intensity may carry both risks and benefits for disordered eating. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Review of Twitter for infectious diseases clinicians: useful or a waste of time?
Goff, Debra A; Kullar, Ravina; Newland, Jason G
2015-05-15
Twitter is a social networking service that has emerged as a valuable tool for healthcare professionals (HCPs). It is the only platform that allows one to connect, engage, learn, and educate oneself and others in real time on a global scale. HCPs are using social media tools to communicate, educate, and engage with their peers worldwide. Twitter allows HCPs to deliver easily accessible "real-time" clinical information on a global scale. Twitter has more than 500 million active users who generate more than 58 million tweets and 2.1 billion search queries every day. Here, we explain why Twitter is important, how and when an infectious diseases (ID) HCP should use Twitter, the impact it has in disseminating ID news, and its educational value. We also describe various tools within Twitter, such as Twitter Chat, that connect and bond HCPs on a specific topic. Twitter may help ID HCPs teach others about the global responsible use of antimicrobials in a world of escalating antimicrobial resistance. © The Author 2015.

Social media as a shield: Facebook buffers acute stress.
Rus, Holly M; Tiemensma, Jitske
2018-03-01
Facebook remains the most widely used social media platform. Research suggests that Facebook may both enhance and undermine psychosocial constructs related to well-being, and that it may impair physiological stress recovery. However, little is known about its influence on stress reactivity. Using novel experimental methods, this study examined how Facebook influences reactivity to an acute social stressor. Facebook users (n=104, 53 males, mean age 19.50, SD=1.73) were randomly assigned to use their own Facebook account or sit quietly with the option of reading electronic magazines before experiencing an acute social stressor. All participants showed significant changes in subjective and physiological stress markers in response to the stressor. However, participants who used Facebook experienced lower levels of psychosocial stress, physiological stress, and rated the stressor as less threatening (p's<0.05) when controlling for gender and emotional investment in the website compared to controls. Results suggest that Facebook use may buffer stress-in particular psychosocial stress-if used before experiencing an acute social stressor. This study is among the first to incorporate both objective and subjective measures in investigating the complex relationship between Facebook use and well-being. Copyright © 2017 Elsevier Inc.

Real-Time Diffusion of Information on Twitter and the Financial Markets.
Tafti, Ali; Zotti, Ryan; Jank, Wolfgang
2016-01-01
Do spikes in Twitter chatter about a firm precede unusual stock market trading activity for that firm? If so, Twitter activity may provide useful information about impending financial market activity in real-time. We study the real-time relationship between chatter on Twitter and the stock trading volume of 96 firms listed on the Nasdaq 100, during 193 days of trading in the period from May 21, 2012 to September 18, 2013. We identify observations featuring firm-specific spikes in Twitter activity, and randomly assign each observation to a ten-minute increment matching on the firm and a number of repeating time indicators. We examine the extent that unusual levels of chatter on Twitter about a firm portend an oncoming surge of trading of its stock within the hour, over and above what would normally be expected for the stock for that time of day and day of week. We also compare the findings from our explanatory model to the predictive power of Tweets. Although we find a compelling and potentially informative real-time relationship between Twitter activity and trading volume, our forecasting exercise highlights how difficult it can be to make use of this information for monetary gain.

Background The Food and Drug Administration (FDA) issues drug safety communications (DSCs) to health care professionals, patients, and the public when safety issues emerge related to FDA-approved drug products. These safety messages are disseminated through social media to ensure broad uptake. Objective The objective of this study was to assess the social media dissemination of 2 DSCs released in 2013 for the sleep aid zolpidem. Methods We used the MedWatcher Social program and the DataSift historic query tool to aggregate Twitter and Facebook posts from October 1, 2012 through August 31, 2013, a period beginning approximately 3 months before the first DSC and ending 3 months after the second. Posts were categorized as (1) junk, (2) mention, and (3) adverse event (AE) based on a score between –0.2 (completely unrelated) to 1 (perfectly related). We also looked at Google Trends data and Wikipedia edits for the same time period. Google Trends search volume is scaled on a range of 0 to 100 and includes “Related queries” during the relevant time periods. An interrupted time series (ITS) analysis assessed the impact of DSCs on the counts of posts with specific mention of zolpidem-containing products. Chow tests for known structural breaks were conducted on data from Twitter, Facebook, and Google Trends. Finally, Wikipedia edits were pulled from the website’s editorial history, which lists all revisions to a given page and the editor’s identity. Results In total, 174,286 Twitter posts and 59,641 Facebook posts met entry criteria. Of those, 16.63% (28,989/174,286) of Twitter posts and 25.91% (15,453/59,641) of Facebook posts were labeled as junk and excluded. AEs and mentions represented 9.21% (16,051/174,286) and 74.16% (129,246/174,286) of Twitter posts and 5.11% (3,050/59,641) and 68.98% (41,138/59,641) of Facebook posts, respectively. Total daily counts of posts about zolpidem-containing products increased on Twitter and Facebook on the day of the first DSC

Chu, Kar-Hai; Unger, Jennifer B.; Cruz, Tess Boley; Soto, Daniel W.
2016-01-01
Objectives Social media platforms are used by tobacco companies to promote products. This study examines message content on Twitter from e-cigarette brands and determines if messages about flavors are more likely than non-flavor messages to be passed along to other viewers. Methods We examined Twitter data from 2 e-cigarette brands and identified messages that contained terms related to e-cigarette flavors. Results Flavor-related posts were retweeted at a significantly higher rate by e-cigarette brands (p = .04) and other Twitter users (p < .01) than non-flavor posts. Conclusions E-cigarette brands and other Twitter users pay attention to flavor-related posts and retweet them often. These findings suggest flavors continue to be an attractive characteristic and their marketing should be monitored closely. PMID:27853734

Older adolescents' views regarding participation in Facebook research.
Moreno, Megan A; Grant, Alison; Kacvinsky, Lauren; Moreno, Peter; Fleming, Michael
2012-11-01
Facebook continues to grow in popularity among adolescents as well as adolescent researchers. Guidance on conducting research using Facebook with appropriate attention to privacy and ethics is scarce. To inform such research efforts, the purpose of this study was to determine older adolescents' responses after learning that they were participants in a research study that involved identification of participants using Facebook. Public Facebook profiles of older adolescents aged 18-19 years from a large state university were examined. Profile owners were then interviewed. During the interview, participants were informed that they were identified by examining publicly available Facebook profiles. Participants were asked to discuss their views on this research method. A total of 132 participants completed the interview (70% response rate); the average age was 18.4 years (SD = .5); and our sample included 64 male participants (48.5%). Participant responses included endorsement (19.7%), fine (36.4%), neutral (28.8%), uneasy (9.1%), and concerned (6.1%). Among participants who were uneasy or concerned, the majority voiced confusion regarding their current profile security settings (p = .00). The majority of adolescent participants viewed the use of Facebook for research positively. These findings are consistent with the approach taken by many U.S. courts. Researchers may consider these findings when developing research protocols involving Facebook. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Codified Hashtags for Weather Warning on Twitter: an Italian Case Study
Grasso, Valentina; Crisci, Alfonso
2016-01-01
Introduction: During emergencies increasing numbers of messages are shared through social media platforms becoming a primary source of information for lay people and emergency managers. For Twitter codified hashtagging is emerging as a practical way to coordinate messages during emergencies and quickly identify relevant information. This paper considers a case study on the use of codified hashtags concerning weather warning in Italy in three different regions. Methods: From November 3rd to December 2nd 2014, tweets identified by the 3 codified hashtags #allertameteoTOS, #allertameteoLIG and #allertameteoPIE were retrieved, collecting a total of 35,558 tweets published by 7361 unique tweets authors, with the aim to assess if codified hashtags could represent an effective way to align formal and informal sources of information during weather related emergencies. An auxiliary R-package was built to lead the analytics used in this study. Authors performed a manual coding of users, hashtags and content of messages of all Twitter data considered. Results: Content analysis showed that tweets were overwhelmingly related to situational updates, with a high percentage containing geo-location information. Communication patterns of different user types were discussed for the three contexts. In accordance with previous studies, individuals showed an active participation primarily functioning as information hub during the emergency. Discussion: In the proposed cases codified hashtags have proven to be an effective tool to convey useful information on Twitter by formal and informal sources. Where institutions supported the use of the predefined hashtag in communication activities, like in Tuscany, messages were very focused, with more than 90% of tweets being situational updates. In this perspective, use of codified hashtags may potentially improve the performance of systems for automatic information retrieval and processing during disasters. Keywords: social media, emergency
Communicating Genetics and Smoking Through Social Media: Are We There Yet?
Suggs, L Suzanne; Brand, Angela; Van Oyen, Herman
2013-01-01
Background Social media is a recent source of health information that could disseminate new scientific research, such as the genetics of smoking. Objective The objectives were (1) to evaluate the availability of genetic information about smoking on different social media platforms (ie, YouTube, Facebook, and Twitter) and (2) to assess the type and the content of the information displayed on the social media as well as the profile of people publishing this information. Methods We screened posts on YouTube, Facebook, and Twitter with the terms “smoking” and “genetic” at two time points (September 18, 2012, and May 7, 2013). The first 100 posts were reviewed for each media for the time points. Google was searched during Time 2 as an indicator of available information on the Web and the other social media that discussed genetics and smoking. The source of information, the country of the publisher, characteristics of the posts, and content of the posts were extracted. Results On YouTube, Facebook, and Twitter, 31, 0, and 84 posts, respectively, were included. Posts were mostly based on smoking-related diseases, referred to scientific publications, and were largely from the United States. From the Google search, most results were scientific databases. Six scientific publications referred to within the Google search were also retrieved on either YouTube or Twitter. Conclusions Despite the importance of public understanding of smoking and genetics, and the high use of social media, little information on this topic is actually present on social media. Therefore, there is a need to monitor the information that is there and to evaluate the population’s understanding of the information related to genetics and smoking that is displayed on social media.

Exploring the use of a Facebook page in anatomy education.
Jaffar, Akram Abood
2014-01-01
Facebook is the most popular social media site visited by university students on a daily basis. Consequently, Facebook is the logical place to start with for integrating social media technologies into education. This study explores how a faculty-administered Facebook Page can be used to supplement anatomy education beyond the traditional classroom. Observations were made on students' perceptions and effectiveness of using the Page, potential benefits and challenges of such use, and which Insights metrics best reflect user's engagement. The Human Anatomy Education Page was launched on Facebook and incorporated into anatomy resources for 157 medical students during two academic years. Students' use of Facebook and their perceptions of the Page were surveyed. Facebook's "Insights" tool was also used to evaluate Page performance during a period of 600 days. The majority of in-class students had a Facebook account which they adopted in education. Most students perceived Human Anatomy Education Page as effective in contributing to learning and favored "self-assessment" posts. The majority of students agreed that Facebook could be a suitable learning environment. The "Insights" tool revealed globally distributed fans with considerable Page interactions. The use of a faculty-administered Facebook Page provided a venue to enhance classroom teaching without intruding into students' social life. A wider educational use of Facebook should be adopted not only because students are embracing its use, but for its inherent potentials in boosting learning. The "Insights" metrics analyzed in this study might be helpful when establishing and evaluating the performance of education-oriented Facebook Pages. © 2013 American Association of Anatomists.
Content Analysis of Tobacco-related Twitter Posts
Myslín, Mark; Zhu, Shu-Hong; Conway, Michael
2013-01-01
Objective We present results of a content analysis of tobacco-related Twitter posts (tweets), focusing on tweets referencing e-cigarettes and hookah. Introduction Vast amounts of free, real-time, localizable Twitter data offer new possibilities for public health workers to identify trends and attitudes that more traditional surveillance methods may not capture, particularly in emerging areas of public health concern where reliable statistical evidence is not readily accessible. Existing applications include tracking public informedness during disease outbreaks [1]. Twitter-based surveillance is particularly suited to new challenges in tobacco control. Hookah and e-cigarettes have surged in popularity, yet regulation and public information remain sparse, despite controversial health effects [2,3]. Ubiquitous online marketing of these products and their popularity among new and younger users make Twitter a key resource for tobacco surveillance. Methods We collected 7,300 tobacco-related Twitter posts at 15-day intervals from December 2011 to July 2012, using ten general keywords such as cig* and hookah. Each tweet was manually classified using a tri-axial scheme, capturing genre (firsthand experience, joke, news, …), theme (underage usage, health, social image, …), and sentiment (positive, negative, neutral). Machine-learning classifiers were trained to detect tobacco-related vs. irrelevant tweets as well as each of the above categories, using Naïve Bayes, k-Nearest Neighbors, and Support Vector Machine algorithms. Finally, phi correlation coefficients were computed between each of the categories to discover emergent patterns. Results The most prevalent genre of tweets was personal experience, followed by categories such as opinion, marketing, and news. The most common themes were hookah, cessation, and social image, and sentiment toward tobacco was more positive (26%) than negative (20%). The most highly correlated categories were social image
Young, black, and connected: Facebook usage among African American college students.
Lee, E Bun
2012-01-01
This article examines the extent and intensity of Facebook usage among African American college students and investigates their reasons for using Facebook. As expected, 98% of students in the survey had a Facebook account, and a large number of Facebook “friends.” Younger users spent significantly more time on Facebook than older ones. Our findings underscore the importance of cultural influence for African American online users. Displaying photographs and personal interests on Facebook signals racial identity among African American college students. Personality traits, such as self-esteem, trust in people, satisfaction with university life, and racial identity, were not significant predictors on the time spent on Facebook.

Identifying Sentiment of Hookah-Related Posts on Twitter
Ramanujam, Jagannathan; Lerman, Kristina; Chu, Kar-Hai; Boley Cruz, Tess; Unger, Jennifer B
2017-01-01
Background The increasing popularity of hookah (or waterpipe) use in the United States and elsewhere has consequences for public health because it has similar health risks to that of combustible cigarettes. While hookah use rapidly increases in popularity, social media data (Twitter, Instagram) can be used to capture and describe the social and environmental contexts in which individuals use, perceive, discuss, and are marketed this tobacco product. These data may allow people to organically report on their sentiment toward tobacco products like hookah unprimed by a researcher, without instrument bias, and at low costs. Objective This study describes the sentiment of hookah-related posts on Twitter and describes the importance of debiasing Twitter data when attempting to understand attitudes. Methods Hookah-related posts on Twitter (N=986,320) were collected from March 24, 2015, to December 2, 2016. Machine learning models were used to describe sentiment on 20 different emotions and to debias the data so that Twitter posts reflected sentiment of legitimate human users and not of social bots or marketing-oriented accounts that would possibly provide overly positive or overly negative sentiment of hookah. Results From the analytical sample, 352,116 tweets (59.50%) were classified as positive while 177,537 (30.00%) were classified as negative, and 62,139 (10.50%) neutral. Among all positive tweets, 218,312 (62.00%) were classified as highly positive emotions (eg, active, alert, excited, elated, happy, and pleasant), while 133,804 (38.00%) positive tweets were classified as passive positive emotions (eg, contented, serene, calm, relaxed, and subdued). Among all negative tweets, 95,870 (54.00%) were classified as subdued negative emotions (eg, sad, unhappy, depressed, and bored) while the remaining 81,667 (46.00%) negative tweets were classified as highly negative emotions (eg, tense, nervous, stressed, upset, and unpleasant). Sentiment changed drastically when

Social Media has taken the world by surprise at a swift and commendable pace. With the advent of any kind of circumstances may it be related to social, political or current affairs the sentiments of people throughout the world are expressed through their help, making them suitable candidates for sentiment mining. Sentimental analysis becomes highly resourceful for any organization who wants to analyse and enhance their products and services. In the airline industries it is much easier to get feedback from astute data source such as Twitter, for conducting a sentiment analysis on their respective customers. The beneficial factors relating to twitter sentiment analysis cannot be impeded by the consumers who want to know the who’s who and what’s what in everyday life. In this paper we are classifying sentiment of Twitter messages by exhibiting results of a machine learning algorithm using R and Rapid Miner. The tweets are extracted and pre-processed and then categorizing them in neutral, negative and positive sentiments finally summarising the results as a whole. The Naive Bayes algorithm has been used for classifying the sentiments of recent tweets done on the different airlines.
Communication about childhood obesity on Twitter.
Harris, Jenine K; Moreland-Russell, Sarah; Tabak, Rachel G; Ruhr, Lindsay R; Maier, Ryan C
2014-07-01
Little is known about the use of social media as a tool for health communication. We used a mixed-methods design to examine communication about childhood obesity on Twitter. NodeXL was used to collect tweets sent in June 2013 containing the hashtag #childhoodobesity. Tweets were coded for content; tweeters were classified by sector and health focus. Data were also collected on the network of follower connections among the tweeters. We used descriptive statistics and exponential random graph modeling to examine tweet content, characteristics of tweeters, and the composition and structure of the network of connections facilitating communication among tweeters. We collected 1110 tweets originating from 576 unique Twitter users. More individuals (65.6%) than organizations (32.9%) tweeted. More tweets focused on individual behavior than environment or policy. Few government and educational tweeters were in the network, but they were more likely than private individuals to be followed by others. There is an opportunity to better disseminate evidence-based information to a broad audience through Twitter by increasing the presence of credible sources in the #childhoodobesity conversation and focusing the content of tweets on scientific evidence.
The Facebook Influence Model: A Concept Mapping Approach
Kota, Rajitha; Schoohs, Shari; Whitehill, Jennifer M.
2013-01-01
Abstract Facebook is a popular social media Web site that has been hypothesized to exert potential influence over users' attitudes, intentions, or behaviors. The purpose of this study was to develop a conceptual framework to explain influential aspects of Facebook. This mixed methods study applied concept mapping methodology, a validated five-step method to visually represent complex topics. The five steps comprise preparation, brainstorming, sort and rank, analysis, and interpretation. College student participants were identified using purposeful sampling. The 80 participants had a mean age of 20.5 years, and included 36% males. A total of 169 statements were generated during brainstorming, and sorted into between 6 and 22 groups. The final concept map included 13 clusters. Interpretation data led to grouping of clusters into four final domains, including connection, comparison, identification, and Facebook as an experience. The Facebook Influence Concept Map illustrates key constructs that contribute to influence, incorporating perspectives of older adolescent Facebook users. While Facebook provides a novel lens through which to consider behavioral influence, it can best be considered in the context of existing behavioral theory. The concept map may be used toward development of potential future intervention efforts. PMID:23621717

Sugawara, Yuya; Narimatsu, Hiroto; Tsuya, Atsushi; Tanaka, Atsushi; Fukao, Akira
2016-01-01
Twitter is a free social networking and microblogging service on the Internet. Medical professionals and patients have started to use Twitter in medicine. Twitter use by medical institutions can interactively and efficiently provide public health information and education for laypeople. This study examined Twitter usage by medical institutions. We reviewed all Japanese user accounts in which the names of medical institutions were described in the user's Twitter profile. We then classified medical institutions' tweets by content. We extracted 168 accounts for medical institutions with ≥500 followers. The medical specialties of those accounts were dentistry and oral surgery (n=73), dermatology (n=12), cosmetic surgery (n=10), internal medicine (n=10), ophthalmology (n=6), obstetrics and gynecology (n=5), plastic surgery (n=2), and others (n=50). Of these, 21 accounts tweeted medical knowledge and 45 accounts tweeted guidance about medical practice and consultation hours, including advertisements. In the dentistry and oral surgery accounts, individual behavior or thinking was the most frequent (22/71, 31%) content. On the other hand, consultation including advertisements was the most frequent (14/23, 61%) in cosmetic surgery, plastic surgery, and dermatology. Some medical specialties used Twitter for disseminating medical knowledge or guidance including advertisements. This indicates that Twitter potentially can be used for various purposes by different medical specialties.

The objectives of this short report are to: (i) explore #Frailty Twitter activity over a six-month period; and (ii) provide a snapshot Twitter content analysis of #Frailty usage. A mixed-method study was conducted to explore Twitter data related to frailty. The primary search term was #Frailty. Objective 1: data were collected using Symplur analytics, including variables for total number of tweets, unique tweeters (users) and total number of impressions. Objective 2: a retrospectively conducted snapshot content analysis of 1500 #Frailty tweets was performed using TweetReach ™ . Over a six-month period (1 January 2017-31 June 2017), there was a total of 6545 #Frailty tweets, generating 14.8 million impressions across 3986 participants. Of the 1500 tweets (814 retweets; 202 replies; 484 original tweets), 56% were relevant to clinical frailty. The main contributors ('who') were as follows: the public (29%), researchers (25%), doctors (21%), organisations (18%) and other allied health professionals (7%). Tweet main message intention ('what') was public health/advocacy (41%), social communication (28%), research-based evidence/professional education (24%), professional opinion/case studies (15%) and general news/events (7%). Twitter is increasingly being used to communicate about frailty. It is important that thought leaders contribute to the conversation. There is potential to leverage Twitter to promote and disseminate frailty-related knowledge and research. © 2018 AJA Inc.

Social Networking Addiction among Health Sciences Students in Oman
Masters, Ken
2015-01-01
Objectives: Addiction to social networking sites (SNSs) is an international issue with numerous methods of measurement. The impact of such addictions among health science students is of particular concern. This study aimed to measure SNS addiction rates among health sciences students at Sultan Qaboos University (SQU) in Muscat, Oman. Methods: In April 2014, an anonymous English-language six-item electronic self-reporting survey based on the Bergen Facebook Addiction Scale was administered to a non-random cohort of 141 medical and laboratory science students at SQU. The survey was used to measure usage of three SNSs: Facebook (Facebook Inc., Menlo Park, California, USA), YouTube (YouTube, San Bruno, California, USA) and Twitter (Twitter Inc., San Francisco, California, USA). Two sets of criteria were used to calculate addiction rates (a score of 3 on at least four survey items or a score of 3 on all six items). Work-related SNS usage was also measured. Results: A total of 81 students completed the survey (response rate: 57.4%). Of the three SNSs, YouTube was most commonly used (100%), followed by Facebook (91.4%) and Twitter (70.4%). Usage and addiction rates varied significantly across the three SNSs. Addiction rates to Facebook, YouTube and Twitter, respectively, varied according to the criteria used (14.2%, 47.2% and 33.3% versus 6.3%, 13.8% and 12.8%). However, addiction rates decreased when work-related activity was taken into account. Conclusion: Rates of SNS addiction among this cohort indicate a need for intervention. Additionally, the results suggest that addiction to individual SNSs should be measured and that work-related activities should be taken into account during measurement. PMID:26357556

Recruitment and retention of young adult veteran drinkers using Facebook
Pedersen, Eric R.; Naranjo, Diana; Marshall, Grant N.
2017-01-01
The objective of this study was to describe the feasibility of using Facebook as a platform to recruit and retain young adult veteran drinkers into an online-alcohol use intervention study. Facebook’s wide accessibility and popularity among the age group that comprises the majority of veterans from the conflicts in Iraq and Afghanistan make it a compelling resource through which research can extend its reach to this otherwise hard-to-reach group. We developed a series of Facebook advertisement campaigns to reach veteran drinkers not specifically searching for alcohol treatment. In doing so, we recruited 793 valid veteran participants in approximately two weeks for an advertising cost of $4.53 per obtained participant. The study sample consisted primarily of male veterans, between 19 and 34 years of age, who were drinking at moderate to heavy levels. Although about half of the sample reported mental health comorbidity, few had received any mental health or substance use treatment in the past year. Facebook appears to be a valuable mechanism through which to recruit young veterans with unmet behavioral health needs, although more specific efforts may be needed to engage certain types of veterans after initial study enrollment.

Background Social networking sites, in particular Facebook, are not only predominant in students’ social life but are to varying degrees interwoven with the medical curriculum. Particularly, Facebook groups have been identified for their potential in higher education. However, there is a paucity of data on user types, content, and dynamics of study-related Facebook groups. Objective The aim of this study was to identify the role of study-related Facebook group use, characterize medical students that use or avoid using Facebook groups (demographics, participation pattern, and motivation), and analyze student posting behavior, covered topics, dynamics, and limitations in Facebook groups with regards to educational usage. Methods Using a multi-method approach (interviews, focus groups, and qualitative and quantitative analysis of Facebook posts), we analyzed two representative Facebook groups of medical preclinical semesters at Ludwig-Maximilians-University (LMU) Munich. Facebook primary posts and replies over one semester were extracted and evaluated by using thematic content analysis. We developed and applied a coding scheme for studying the frequency and distribution of these posts. Additionally, we interviewed students with various degrees of involvement in the groups, as well as “new minorities,” students not registered on Facebook. Results Facebook groups seem to have evolved as the main tool for medical students at LMU to complement the curriculum and to discuss study-related content. These Facebook groups are self-organizing and quickly adapt to organizational or subject-related challenges posed by the curriculum. A wide range of topics is covered, with a dominance of organization-related posts (58.35% [6916/11,853] of overall posts). By measuring reply rates and comments per category, we were able to identify learning tips and strategies, material sharing, and course content discussions as the most relevant categories. Rates of adequate replies in these

Over 500 million people interact daily with Facebook. Yet, whether Facebook use influences subjective well-being over time is unknown. We addressed this issue using experience-sampling, the most reliable method for measuring in-vivo behavior and psychological experience. We text-messaged people five times per day for two-weeks to examine how Facebook use influences the two components of subjective well-being: how people feel moment-to-moment and how satisfied they are with their lives. Our results indicate that Facebook use predicts negative shifts on both of these variables over time. The more people used Facebook at one time point, the worse they felt the next time we text-messaged them; the more they used Facebook over two-weeks, the more their life satisfaction levels declined over time. Interacting with other people "directly" did not predict these negative outcomes. They were also not moderated by the size of people's Facebook networks, their perceived supportiveness, motivation for using Facebook, gender, loneliness, self-esteem, or depression. On the surface, Facebook provides an invaluable resource for fulfilling the basic human need for social connection. Rather than enhancing well-being, however, these findings suggest that Facebook may undermine it.

Background The recent Zika outbreak witnessed the disease evolving from a regional health concern to a global epidemic. During this process, different communities across the globe became involved in Twitter, discussing the disease and key issues associated with it. This paper presents a study of this discussion in Twitter, at the nexus of location, actors, and concepts. Objective Our objective in this study was to demonstrate the significance of 3 types of events: location related, actor related, and concept related, for understanding how a public health emergency of international concern plays out in social media, and Twitter in particular. Accordingly, the study contributes to research efforts toward gaining insights on the mechanisms that drive participation, contributions, and interaction in this social media platform during a disease outbreak. Methods We collected 6,249,626 tweets referring to the Zika outbreak over a period of 12 weeks early in the outbreak (December 2015 through March 2016). We analyzed this data corpus in terms of its geographical footprint, the actors participating in the discourse, and emerging concepts associated with the issue. Data were visualized and evaluated with spatiotemporal and network analysis tools to capture the evolution of interest on the topic and to reveal connections between locations, actors, and concepts in the form of interaction networks. Results The spatiotemporal analysis of Twitter contributions reflects the spread of interest in Zika from its original hotspot in South America to North America and then across the globe. The Centers for Disease Control and World Health Organization had a prominent presence in social media discussions. Tweets about pregnancy and abortion increased as more information about this emerging infectious disease was presented to the public and public figures became involved in this. Conclusions The results of this study show the utility of analyzing temporal variations in the analytic
Do you "like" my photo? Facebook use maintains eating disorder risk.

Social media sites, such as Facebook, merge two factors that influence risk for eating disorders:media and peers. Previous work has identified cross-sectional and temporal associations between Facebook use and disordered eating. This study sought to replicate and extend these findings using an experimental design. In Study 1, 960 women completed self-report surveys regarding Facebook use and disordered eating. In Study 2, 84 women were randomly assigned to use Facebook or to use an alternate internet site for 20 min. More frequent Facebook use was associated with greater disordered eating in a cross-sectional survey. Facebook use was associated with the maintenance of weight/shape concerns and state anxiety compared to an alternate internet activity. Facebook use may contribute to disordered eating by maintaining risk for eating pathology. As such, targeting Facebook use may be helpful in intervention and prevention programs.

Do spikes in Twitter chatter about a firm precede unusual stock market trading activity for that firm? If so, Twitter activity may provide useful information about impending financial market activity in real-time. We study the real-time relationship between chatter on Twitter and the stock trading volume of 96 firms listed on the Nasdaq 100, during 193 days of trading in the period from May 21, 2012 to September 18, 2013. We identify observations featuring firm-specific spikes in Twitter activity, and randomly assign each observation to a ten-minute increment matching on the firm and a number of repeating time indicators. We examine the extent that unusual levels of chatter on Twitter about a firm portend an oncoming surge of trading of its stock within the hour, over and above what would normally be expected for the stock for that time of day and day of week. We also compare the findings from our explanatory model to the predictive power of Tweets. Although we find a compelling and potentially informative real-time relationship between Twitter activity and trading volume, our forecasting exercise highlights how difficult it can be to make use of this information for monetary gain.

Social network sites (SNS) are a novel social environment for college students with psychological distress to connect with their peers, but the nature and effects of these interactions are not well understood. This study reports findings from a Facebook study among 238 college students reporting nonspecific psychological distress using the K-6 scale. Behavioral data included Facebook status updates containing affect words written by participants within the past 60 days and the number of responses (comments and likes) each update received. The updates were also coded for depression symptoms. Self-report data included participants' self-presentational concerns, the affective valence of each post, effects of responses on mood, and satisfaction with the responses to and outcome of each status update. Higher psychological distress was associated with displaying depression language on Facebook, with higher self-presentational concerns, and with less satisfaction with audiences' responses and less overall satisfaction with the outcome of the interaction. These results offer a unique glimpse into the social world of college students with psychological distress through their everyday use of Facebook, and how the interplay of this novel environment and students' mental health impacts their social behaviors and interaction meaning-making on Facebook.

Public confidence in an immunization programme is a pivotal determinant of the programme's success. The mining of social media is increasingly employed to provide insight into the public's sentiment. This research further explores the value of monitoring social media to understand public sentiment about an international vaccination programme. To gain insight into international public discussion on the paediatric pentavalent vaccine (DTP-HepB-Hib) programme by analysing Twitter messages. Using a multilingual search, we retrospectively collected all public Twitter messages mentioning the DTP-HepB-Hib vaccine from July 2006 until May 2015. We analysed message characteristics by frequency of referencing other websites, type of websites, and geographic focus of the discussion. In addition, a sample of messages was manually annotated for positive or negative message tone. We retrieved 5771 messages. Only 3.1% of the messages were reactions to other messages, and 86.6% referred to websites, mostly news sites (70.7%), other social media (9.8%), and health-information sites (9.5%). Country mentions were identified in 70.4% of the messages, of which India (35.4%), Indonesia (18.3%), and Vietnam (13.9%) were the most prevalent. In the annotated sample, 63% of the messages showed a positive or neutral sentiment about DTP-HepB-Hib. Peaks in negative and positive messages could be related to country-specific programme events. Public messages about DTP-HepB-Hib were characterized by little interaction between tweeters, and by frequent referencing of websites and other information links. Twitter messages can indirectly reflect the public's opinion about major events in the debates about the DTP-HepB-Hib vaccine. Copyright © 2016 Elsevier Ltd. All rights reserved.

Astronauts experience structural changes to their heart during long-duration spaceflight, but the biological basis of that is not clearly understood. Jonathon Baio, a doctoral student at Loma Linda University’s School of Medicine, details an investigation of cardiovascular stem cells that hopes to better understand their role in cardiac biology and tissue regeneration, which could advance ways to maintain cardiac health of astronauts during extended missions as well inform future treatments to reverse heart muscle loss upon return to Earth, and may help the medical community combat cardiovascular disease, one of the world’s leading causes of death.

Major social networking platforms, such as Facebook, WhatsApp, and Twitter, have become popular means through which people share health-related information, irrespective of whether messages disseminated through these channels are authentic. This study aims to describe the demographic characteristics of patients that may demonstrate their attitudes toward medical information shared on social media networks. Second, we address how information found through social media affects the way people deal with their health. Third, we examine whether patients initiate or alter/discontinue their medications based on information derived from social media. We conducted a cross-sectional survey between April and June 2015 on patients attending outpatient clinics at King Abdulaziz University, Jeddah, Saudi Arabia. Patients who used social media (Facebook, WhatsApp, and Twitter) were included. We designed a questionnaire with closed-ended and multiple-choice questions to assess the type of social media platforms patients used and whether information received on these platforms influenced their health care decisions. We used chi-square test to establish the relationship between categorical variables. Of the 442 patients who filled in the questionnaires, 401 used Facebook, WhatsApp, or Twitter. The majority of respondents (89.8%, 397/442) used WhatsApp, followed by Facebook (58.6%, 259/442) and Twitter (42.3%, 187/442). In most cases, respondents received health-related messages from WhatsApp and approximately 42.6% (171/401) reported ever stopping treatment as advised on a social media platform. A significantly higher proportion of patients without heart disease (P=.001) and obese persons (P=.01) checked the authenticity of information received on social media. Social media messages influenced decision making among patients without heart disease (P=.04). Respondents without heart disease (P=.001) and obese persons (P=.01) were more likely to discuss health-related information

Facebook has become a widely used online self-representation and communication platform. In this research, we focus on emotional disclosure on Facebook. We conducted two studies, and results from both self-report and observer rating show that individuals are more likely to express positive relative to negative emotions and present better emotional well-being on Facebook than in real life. Our study is the first to demonstrate impression management on Facebook through emotional disclosure. We discuss important theoretical and practical implications of our study.
Psychopathological Processes Involved in Social Comparison, Depression, and Envy on Facebook
Pera, Aurel

Is Facebook utilization beneficial or detrimental for psychological well-being? I draw on outstanding research (e.g., Chou and Edge, 2012; Lin and Utz, 2015; Appel et al., 2016; Ehrenreich and Underwood, 2016; Vogel and Rose, 2016; Hu et al., 2017) to substantiate that examining other individuals’ positively presented material on Facebook may have detrimental consequences. Increasing comparisons on Facebook may generate feelings of envy, the latter being a significant process determining the effect of growing social comparison on psychological well-being. To date, there is an increasing body of literature investigating the psychological consequences of Facebook usage, the function of relationship closeness in producing the feelings of contentment and envy, the impacts of exposure to positive content on Facebook, the link between envy and depression on Facebook, and the function of tie strength in expecting the emotional results of browsing Facebook. I am specifically interested in how previous research explored the consequences of Facebook use on psychological outcomes, the moderating function of envy in the link between Facebook use and reduced affective wellbeing, the psychological results of non-interactive Facebook conduct, and the role of relationship closeness in anticipating user’s contentment and envy after inspecting a post. A synthesis of the extant literature suggests that inspecting other individuals’ positive news on Facebook brings about contentment through emotional contagion, whereas negative news causes discomfort as a consequence of mood contagion, the transmissible effect being more powerful when the news is associated with a strong tie. The outcomes of this research back the argument that self-confidence and dispositional envy are instrumental in producing Facebook envy. These findings highlight that the emotional results of browsing Facebook are considerably affected by the substance of the comment, the personal attributes of the Facebook

Online Mate-Retention Tactics on Facebook Are Associated With Relationship Aggression.
Brem, Meagan J; Spiller, Laura C; Vandehey, Michael A
2015-10-01
A measure of Facebook-related mate-retention tactics was developed to investigate the relationship between online behaviors and intimate partner aggression. One hundred and seventy-seven young adults (65 men, 112 women) completed questionnaires that included measures of online and offline mate-retention tactics, Facebook jealousy, Facebook surveillance, and intimate partner violence. A factor analysis yielded four subscales for the Facebook Mate-Retention Tactic Inventory (FMRTI): Care and Affection, Jealousy and Surveillance, Possession Signals, and Punishment of Infidelity Threat. The FMRTI total scores were positively correlated with Facebook jealousy, Facebook surveillance, and use of offline mate-retention tactics. The Jealousy and Surveillance subscale uniquely predicted intimate partner psychological and physical aggression over and above existing measures. Facebook mate-retention tactics fully mediated the relation between Facebook jealousy and both intimate partner psychological and physical aggression. The current study provides preliminary evidence for conceptualizing Facebook as an environment for the use of mate-retention tactics that have real-life implications for intimate partner violence. © The Author(s) 2014.

This study argues for the necessity of applying offline contexts to social networking site research and the importance of distinguishing the relationship types of users' counterparts when studying Facebook users' behaviors. In an attempt to examine the relationship among users' behaviors, their counterparts' relationship types, and the users' perceived acquaintanceships after using Facebook, this study first investigated users' frequently used tools when interacting with different types of friends. Users tended to use less time- and effort-consuming and less privacy-concerned tools with newly acquired friends. This study further examined users' behaviors in terms of their closeness and intimacy and their perceived acquaintanceships toward four different types of friends. The study found that users gained more perceived acquaintanceships from less close friends with whom users have more frequent interaction but less intimate behaviors. As for closer friends, users tended to use more intimate activities to interact with them. However, these activities did not necessarily occur more frequently than the activities they employed with their less close friends. It was found that perceived acquaintanceships with closer friends were significantly lower than those with less close friends. This implies that Facebook is a mechanism for new friends, rather than close friends, to become more acquainted.
