As a scholarly domain, social media research has come a long way since the term “social media” first appeared in the literature in the early 2000s. Since then, researchers across disciplines have been actively examining the impact of social media on society. According to Web of Science, there are currently over 19,000 academic articles that include the term “social media.” This special issue of American Behavioral Scientist adds to this rapidly growing body of social media research with a focus on exploring (1) networked influence, (2) transmission of (mis)information, and (3) online and offline, which points to an unstated struggle between top-down attempts by governments and large organizations to influence society and bottom-up citizen articulations of needs and actions.

Despite the relevant economic and reputational impact of fraud, research in this field remains fragmented. This study aims to create a new framework for accounting fraud, defining its main components from the social media user’s perspective. In terms of research technique, an online data collection using social media platform was used retrieving, through the phyton web crawler procedure, 43,655 tweets containing the phrase “accounting fraud” from July 2006 to December 2019. Individual words were identified and treated within the selected tweets, excluding stop words and, finally, using a sparsity index. The proposed methodology, which overcomes traditional survey inherent bias efficiently, contributes to bridging the divide between academia and society. We find that Twitter users shape the Accounting Fraud Hexagon, composed by (i) The Object and the Tool (of misrepresentation), being the Financials, (ii) The (Guilty) Fraudster, (iii) The Defrauded, (iv) Materiality, (v) The Consequences, and (vi) the Watchdog. Our research has several implications. Our research identifies additional “angles” of vision to the traditional fraud triangle-diamond-pentagon theories compared with the existing top-down conceptual frameworks. Also, since it uses a bottom-up instead of a top-down approach, the study allows a more comprehensive definition of accounting fraud, thus contributing to the debate for a common language in this field. We expect to encourage more research using social media as a tool to test the literature built on in vitro theories empirically.

Recent debates on the meaning and use of science are focused on addressing citizens’ needs or concerns of society in different fields. Researchers have developed different methodologies for capturing the relevance of topics to be addressed by research in order to map them. This article proposes a new methodology for identifying the relevance of research goals through collecting citizen’s voices on Twitter and Facebook combing two approaches: top down, starting with already defined research goals priorities, and bottom up, departing from the social media. The article presents the results of the application of this methodology through the research goals of Sustainable Development Goals to identify their relevance and if there are some topics not covered by them. Thus, researchers could integrate this methodology in their daily work and be more in line with the needs expressed by citizens in social media.

Social media platforms play an increasing role in politics, facilitating the circulation of populist texts disseminated by politicians, official campaign media, and user-generated content, all of which contribute to voters’ perceptions of politicians and political issues. The networks and affordances of social media platforms allow for the development of an individualized, affective connection with voters, which is a particularly important strategy for far-right politicians, who are often stigmatized. Furthermore, social media enables the circulation of user-generated materials in a form of digital political participation, allowing citizens to respond in real-time to political developments. While digital political participation ostensibly offers the potential for the expression of marginalized perspectives, digital texts predominantly emphasize and enforce existing hierarchies, particularly the supremacy of whiteness. This panel explores visuals and memes circulated on social media through the lenses of platform studies, whiteness studies, nostalgia, and Critical Discourse Analysis. By examining both “top-down” media disseminated by public figures and “bottom-up” user-generated content, this panel provides an in-depth understanding of the social media ecosystems that work to preserve and extend far-right values and white supremacy. Rachel Winter focuses on the influence of official campaign materials on user-generated content, as well as the impacts of both on candidate image management and the racial hierarchy of the United States. An analysis of representations of race in user-generated Rafael “Ted” Cruz and Robert “Beto” O’Rourke memes reveals an embedded valuation of whiteness and white supremacy to the detriment of other racial demographics. Political memes collected from Facebook, Twitter, Instagram, Tumblr, and Reddit uphold the importance of the white racial identity of candidates and, in so doing, attempt to preserve White American identities from the perceived threat of multiculturalism embodied in racially diverse politicians and their constituents. Julia DeCook examines nostalgia and chronotopes in alt-right memes, contending that the emphasis on “tradition” over “progress” is an attempt to unify the alt-right and preserve white identity and supremacy from threats of globalization and feminism. The alt-right creates virtual nation-states that use consistent linguistic strategies to enable these groups to engage in a form of collective action. Examining white supremacist memes from Reddit and Instagram, Panelist 2 explores the ways that time, memory, and the abstract conception of “the past” are used in digital propaganda to appeal to younger voters and emphasize the myth that whiteness must be protected from the threat of multiculturalism.
