Social Balance

With the availability of internet, social media, etc., the interconnectedness of people within most societies has increased tremendously over the past decades. Across the same timespan, an increasing level of fragmentation of society into small isolated groups has been observed. With a simple model of a society, in which the dynamics of individual opinion formation is integrated with social balance, we show that these two phenomena might be tightly related. We identify a critical level of interconnectedness, above which society fragments into sub-communities that are internally cohesive and hostile towards other groups. This critical communication density necessarily exists in the presence of social balance, and arises from the underlying mathematical structure of a phase transition known from the theory of disordered magnets called spin glasses. We discuss the consequences of this phase transition for social fragmentation in society.

True Equilibrium

Over the past decade, a great deal of effort has gone into understanding the properties of spin glasses [1,2]. However, because these are rather unique systems which show simultaneously apparent phase transition as well as metastable or glassy behavior, progress has been slow. Though it was initially believed that spin glasses could be treated as if they had a true equilibrium phase transition, we now recognize that this cannot be the whole story. Recently, it has become clear that spin glasses are very complex systems, in which irreversible and time dependent effects play an important role. We now know that one must go beyond the regime of validity of equilibrium thermodynamics. In this paper, we will discuss the mountinq evidence, both experimental and theoretical, for why nonequilibrium approaches are essential in order to understand spin glasses.

The Relationship

As social media platforms have developed over the past decade, they are no longer simply sites for interactions and networked sociality; they also now facilitate backwards glances to previous times, moments, and events. Users’ past content is turned into definable objects that can be scored, rated, and resurfaced as “memories.” There is, then, a need to understand how metrics have come to shape digital and social media memory practices, and how the relationship between memory, data, and metrics can be further understood. This article seeks to outline some of the relations between social media, metrics, and memory. It examines how metrics shape remembrance of the past within social media. Drawing on qualitative interviews as well as focus group data, the article examines the ways in which metrics are implicated in memory making and memory practices. This article explores the effect of social media “likes” on people’s memory attachments and emotional associations with the past. The article then examines how memory features incentivize users to keep remembering through accumulation. It also examines how numerating engagements leads to a sense of competition in how the digital past is approached and experienced. Finally, the article explores the tensions that arise in quantifying people’s engagements with their memories. This article proposes the notion of quantified nostalgia in order to examine how metrics are variously performative in memory making, and how regimes of ordinary measures can figure in the engagement and reconstruction of the digital past in multiple ways.

Background: Social media posts regarding ulnar collateral ligament (UCL) injuries and reconstruction surgeries have increased in recent years. Purpose: To analyze posts shared on Instagram and Twitter referencing UCL injuries and reconstruction surgeries to evaluate public perception and any trends in perception over the past 3 years. Study Design: Cross-sectional study. Methods: A search of a 3-year period (August 2016 and August 2019) of public Instagram and Twitter posts was performed. We searched for >22 hashtags and search terms, including #TommyJohn, #TommyJohnSurgery, and #tornUCL. A categorical classification system was used to assess the sentiment, media format, perspective, timing, accuracy, and general content of each post. Post popularity was measured by number of likes and comments. Results: A total of 3119 Instagram posts and 267 Twitter posts were included in the analysis. Of the 3119 Instagram posts analyzed, 34% were from patients, and 28% were from providers. Of the 267 Twitter posts analyzed, 42% were from patients, and 16% were from providers. Although the majority of social media posts were of a positive sentiment, over the past 3 years, there was a major surge in negative sentiment posts (97% increase) versus positive sentiment posts (9% increase). Patients were more likely to focus their posts on rehabilitation, return to play, and activities of daily living. Providers tended to focus their posts on education, rehabilitation, and injury prevention. Patient posts declined over the past 3 years (–28%), whereas provider posts increased substantially (110%). Of posts shared by health care providers, 4% of posts contained inaccurate or misleading information. Conclusion: The majority of patients who post about their UCL injury and reconstruction on social media have a positive sentiment when discussing their procedure. However, negative sentiment posts have increased significantly over the past 3 years. Patient content revolves around rehabilitation and return to play. Although patient posts have declined over the past 3 years, provider posts have increased substantially with an emphasis on education.

The Media

Since the introduction of smartphones in 2009, social networking services (SNS), which have seen a surge in users, facilitated changes in the media environment along with social influence that has increased the economic value and political influence of SNS. In particular, as consumers’ media use and consumption behavior change around digital media, social media plays a very important role in consumers’ lives. From this perspective, influencers who influence not only consumers’ consumption behavior, but also decision-making and opinion formation based on social media are attracting attention. Therefore, the aim of this study was to develop items to measure an influencer’s reputation as a new source of information in the SNS environment; no previous researchers have presented generalized measurement items for an influencer’s reputation. We intended to identify what dimensions and items in the existing literature could effectively measure a social media influencer’s reputation and to verify each item’s relevance as a measure of a social media influencer’s reputation. Based on in-depth interviews with 30 experts and empirical findings from 557 adults, this study identified dimensions that impact on a consumer’s perception of a social media influencer and developed a scale. The results showed that the social media Influencer’s Reputation scale comprises four distinctive dimensions: Communication skills, influence, authenticity, and expertise. Additionally, the reliability and validity of the scale were assessed, using exploratory and confirmatory analyses and construct validity. The findings confirmed that the social media influencer’s reputation scale measurement items, in this study, can be used as a consistent measurement tool for each dimension. It is also important to develop value in favor of the marketing strategy by increasing value through the influencer’s reputation.

The Relationship

This paper examines the relationship between political candidates' use of Facebook and their election outcomes (vote share and election success). The use of social media in political marketing campaigns has grown dramatically over the past few years. It is also expected to become even more critical to future political campaigns, as it creates two-way communication and engagement that stimulates and fosters candidates' relationships with their supporters. Online Facebook data were acquired for all 84 candidates running in a municipal election in Taiwan. Results suggest that a candidate's Facebook presence, the type of account they use, the authentication of the account, and the number of online fans they have are related to their election outcomes.

The Media

Sports reporters depend on access to events and sources as much or more than any other news professional. Over the past few years, some sports organizations have attempted to restrict such access, as well as what reporters can publish via social media. In the digital era, access and publishing autonomy, as institutionalized concepts, are evolving rapidly. Hypotheses tying access and work practices to reporters’ perceptions of the legitimacy they experience are developed and tested via a structural equation model, using responses to a survey of journalists in American intercollegiate athletics and observed dimensions of access and autonomy to measure a latent variable of legitimacy. The model suggests that reporters have mixed views about whether they possess the legitimacy they need to do their jobs.
