Detection And Localization

Digital videos are now low-cost, easy to capture and easy to share on social media due to the common feature of video recording in smart phones and digital devices. However, with the advancement of video editing tools, videos can be tampered (forged) easily for propaganda or to gain illegal advantages—ultimately, the authenticity of videos shared on social media cannot be taken for granted. Over the years, significant research has been devoted to developing new techniques for detecting different types of video tampering. In this paper, we offer a detailed review of existing passive video tampering detection techniques in a systematic way. The answers to research questions prepared for this study are also elaborated. The state-of-the-art research work is analyzed extensively, highlighting the pros and cons and commonly used datasets. Limitations of existing video forensic algorithms are discussed, and we conclude with research challenges and future directions.

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 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.

In this paper, we examine the relation between social media use and the absorptive capacity of organisations. Over the past 10 years, many organisations have systematically adopted social media. Trade press and consulting companies often claim that the systematic use of social media increases the performance of organisations. However, such claims are typically neither empirically grounded nor theoretically examined. In this paper, based on key informant interviews at 20 organisations, we examine these claims empirically and theoretically. Firstly, we examine the ways in which social media are used by organisations. We identify five different social media use types that support different organisational purposes (broadcast, dialogue, collaboration, knowledge management and sociability). Secondly, we analyse how these five social media use types relate to organisations' absorptive capacity. We find that particular social media use types (e.g., dialogue) support organisations' absorptive capacity and, ultimately, their performance although others (e.g., sociability) do not.

Cyberbullying has become a real and occasionally lethal threat among adolescents during the past years. The act of cyberbullying is often untraceable, leaving victims tormented and routinely harassed on social media. This emerging problem causes depression and anxiety, psychologically affecting our adolescents. With an increase in adolescents’ suicides, cyberbullying should be examined as a risk factor. This case describes how the tragic suicide of a student at Heartsville High School immersed Principal Ivy La Fleur in the middle of a convoluted situation affecting students, parents, and staff. A series of events allowed the seasoned school principal to investigate the matter in depth, discover the struggles students were suffering in terms of cyberbullying, put a plan in place to manage a general crisis affecting the entire educational community, and promote changes to avoid similar situations in the near future.

Abstract This article explores the possibility that public libraries can be repositories for digital community archives. The overarching goal is to establish a case for public libraries’ developing digital community archives that are participatory and which emphasize born-digital items rather than digitized physical items. This discussion follows my own research and experience in this area to include personal information management, social media and the personal archive, and the accidental community archive, and demonstrates that public libraries can focus on communities’ current events and people rather than solely on those from the past.
