PRELIMINARY ANALYSIS OF A PUBLIC HEALTH TWITTER CAMPAIGN: WORLD HEALTH DAY 2014

Public health campaigns aim to positively affect health-related behaviors and/or raise awareness of specific health conditions, risk factors and issues. These campaigns have traditionally relied upon various media and mechanisms for success, such as mass media distribution by television and radio, information propagation by individuals, involvement and engagement of stakeholders, and recruitment to the campaign of celebrities or advocates well known to the community.More recently, microblog platforms such as Twitter have also been increasingly utilized for public health campaign delivery. This is a relatively recent phenomenon and so is not yet well understood or studied. In this paper we provide an initial description of a case study of a global Twitter-based public health campaign, namely that involving the use of the #worldhealthday hashtag during and surrounding the 2014 World Health Day, April 7th 2014.In addition, the various characteristics and properties of this public health campaign within this contemporary medium are explored utilizing software tools that enable the capture and analysis of Twitter information flows

A Survey on Visual Analytics of Social Media Data

The unprecedented availability of social media data offers substantial opportunities for data owners, system operators, solution providers, and end users to explore and understand social dynamics. However, the exponential growth in the volume, velocity, and variability of social media data prevents people from fully utilizing such data. Visual analytics, which is an emerging research direction, ha..

Social Media as a Medium to Promote Local Perception Expression in China’s World Heritage Sites

The assessment of public participation is one of the most fundamental components of holistic and sustainable cultural heritage management. Since the beginning of 2020, the COVID-19 pandemic became a catalyst for the transformation of participatory tools. Collaboration with stakeholders moved online due to the strict restrictions preventing on-site activities. This phenomenon provided an opportunity to formulate more comprehensive and reasonable urban heritage protection strategies. However, very few publications mentioned how social networking sites’ data could support humanity-centred heritage management and participatory evaluation. Taking five World Cultural Heritage Sites as research samples, the study provides a methodology to evaluate online participatory practices in China through Weibo, a Chinese-originated social media platform. The data obtained were analysed from three perspectives: the users’ information, the content of texts, and the attached images. As shown in the results section, individuals’ information is described by gender, geo-location, celebrities, and Key Opinion Leaders. To a greater extent, participatory behaviour emerges at the relatively primary levels, that being “informing and consulting”. According to the label detection of Google Vision, residents paid more attention to buildings, facades, and temples in the cultural heritage sites. The research concludes that using social media platforms to unveil interplays between digital and physical heritage conservation is feasible and should be widely encouraged

Microbloggers’ motivations in participatory journalism: A cross-cultural study of America and China

This phenomenological study focuses on the motivations of participatory journalists contributing on microblogs such as Twitter and Weibo. Although online user behavior and motivations have been studied before, few studies have examined motivations of participatory journalists from their own perspective. Moreover, this study is one of the few to explore participatory journalists across different cultures (U.S. and China). The author conducted a total of 13 in-depth interviews with participatory journalists on microblogs from both countries and used a qualitative analysis method to identify the themes and patterns that emerged. Motivations such as earning respect, technology early adoption, self-expression, relationship building, self-enhancement, branding and image building, and financial gain were discussed. De-motivational factors such as time constraints and self-censorship were presented. Motivational differences between the two groups of participants, including what the microblog account represents and the role of participatory journalists, were explained by cultural differences collectivism versus individualism and power distance. Limitations and future research were also discussed

What people study when they study Tumblr:Classifying Tumblr-related academic research

Purpose: Since its launch in 2007, research has been carried out on the popular social networking website Tumblr. This paper identifies published Tumblr based research, classifies it to understand approaches and methods, and provides methodological recommendations for others. / Design/methodology/approach: Research regarding Tumblr was identified. Following a review of the literature, a classification scheme was adapted and applied, to understand research focus. Papers were quantitatively classified using open coded content analysis of method, subject, approach, and topic. / Findings: The majority of published work relating to Tumblr concentrates on conceptual issues, followed by aspects of the messages sent. This has evolved over time. Perceived benefits are the platform’s long-form text posts, ability to track tags, and the multimodal nature of the platform. Severe research limitations are caused by the lack of demographic, geo-spatial, and temporal metadata attached to individual posts, the limited API, restricted access to data, and the large amounts of ephemeral posts on the site. / Research limitations/implications: This study focuses on Tumblr: the applicability of the approach to other media is not considered. We focus on published research and conference papers: there will be book content which was not found using our method. Tumblr as a platform has falling user numbers which may be of concern to researchers. / Practical implications: We identify practical barriers to research on the Tumblr platform including lack of metadata and access to big data, explaining why Tumblr is not as popular as Twitter in academic studies. - Social implications This paper highlights the breadth of topics covered by social media researchers, which allows us to understand popular online platforms. / Originality/value: There has not yet been an overarching study to look at the methods and purpose of those who study Tumblr. We identify Tumblr related research papers from the first appearing in July 2011 until July 2015. Our classification derived here provides a framework that can be used to analyse social media research, and in which to position Tumblr related work, with recommendations on benefits and limitations of the platform for researchers
