Persistent interaction patterns across social media platforms and over time.

Growing concern surrounds the impact of social media platforms on public discourse1-4 and their influence on social dynamics5-9, especially in the context of toxicity10-12. Here, to better understand these phenomena, we use a comparative approach to isolate human behavioural patterns across multiple social media platforms. In particular, we analyse conversations in different online communities, focusing on identifying consistent patterns of toxic content. Drawing from an extensive dataset that spans eight platforms over 34 years-from Usenet to contemporary social media-our findings show consistent conversation patterns and user behaviour, irrespective of the platform, topic or time. Notably, although long conversations consistently exhibit higher toxicity, toxic language does not invariably discourage people from participating in a conversation, and toxicity does not necessarily escalate as discussions evolve. Our analysis suggests that debates and contrasting sentiments among users significantly contribute to more intense and hostile discussions. Moreover, the persistence of these patterns across three decades, despite changes in platforms and societal norms, underscores the pivotal role of human behaviour in shaping online discourse.

Twenty-Five Years of Social Media: A Review of Social Media Applications and Definitions from 1994 to 2019.

In this article, the authors present the results from a structured review of the literature, identifying and analyzing the most quoted and dominant definitions of social media (SM) and alternative terms that were used between 1994 and 2019 to identify their major applications. Similarities and differences in the definitions are highlighted to provide guidelines for researchers and managers who use results from previous research to further study SM or to find practical applications. In other words, when reading an article about SM, it is essential to understand how the researchers defined SM and how results from articles that use different definitions can be compared. This article is intended to act as a guideline for readers of those articles.

Fertility and Sterility top videos from 2017 to 2019.

OBJECTIVE: To objectively grade all video publications in Fertility and Sterility during the years 2017-2019 and compile a list of the top 10 surgical videos. DESIGN: Descriptive presentation of the 10 highest-scoring video publications from Fertility and Sterility in the years 2017-2019. SETTING: Not applicable. PATIENT(S)/ANIMAL(S): Not applicable. INTERVENTION(S): All 4 authors acted as independent reviewers of all video publications. A standardized scoring method was used to score all videos. MAIN OUTCOME MEASURE(S): Up to 5 points were awarded for each of the following categories: Scientific merit or clinical relevance of the topic; clarity of video; use of innovative surgical technique; and video editing or use of marking tools on the video to highlight important features or surgical landmarks. This allowed a maximum score of 20 for each video. The number of YouTube views and likes were used as a tiebreaker if ≥2 videos scored similarly. The interclass coefficient from a 2-way random effects model was calculated to assess for agreement between the 4 independent reviewers. RESULT(S): A total of 40 videos were published in Fertility and Sterility during the years 2017-2019. After averaging scores from all 4 reviewers, a top 10 list was created (Table). Only 2 videos (number 6 and 7 spots) had the same average score, and the number of YouTube views and likes were used as a tiebreaker. The overall interclass coefficient for the 4 reviewers was 0.68 (95% confidence interval, 0.52-0.76). CONCLUSION(S): An overall substantial agreement was noted between the 4 reviewers. Ten videos reigned supreme from a list of very competitive publications that had already undergone the peer review process. The subject matter of these videos ranged from complex surgical procedures, including uterus transplantation and use of a biologic graft for neovaginoplasty, to common procedures like hysteroscopic removal of intrauterine devices during pregnancy and approaches to the stenotic cervix.

Dan Callahan's Press Clips.

For more than eleven years, I worked with Dan Callahan as an editor, a liaison with journalists, and a sounding board for ideas. To Dan, every new writing project was a thrill, whether it was for the New Republic or a blog. He consumed a wide range of professional and scholarly literature, followed the news with the eye of a reporter, and called experts when he wanted to learn more about something he had read. The result was a volcanic bubbling of story ideas. If he didn't turn them into articles or books, I sometimes had the feeling that he might burst.

The Social Media DNA of Mayo Clinic-and Health Care.

Hippocrates' admonition and the medical community's aversion to risk have caused many physicians and institutions to resist participation in modern social media sites such as Facebook (Facebook, Inc, Menlo Park, California, USA), Twitter (Twitter Inc, San Francisco, California, USA), and YouTube (San Mateo, California, USA). However, because Mayo Clinic's founders were champions of analog social networking, it was among the earliest hospitals worldwide to create official accounts on these digital platforms. A proper understanding of the traditional mechanisms of knowledge diffusion in medicine and of the nature of social media sites should help professionals see and embrace the opportunities for positive engagement in social media.

Young, black, and connected: Facebook usage among African American college students.

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.

Online trust, trustworthiness, or assurance?

Every day, individuals around the world retrieve, share, and exchange information on the Internet. We interact online to share personal information, find answers to questions, make financial transactions, play social games, and maintain professional and personal relationships. Sometimes our online interactions take place between two or more humans. In other cases, we rely on computers to manage information on our behalf. In each scenario, risk and uncertainty are essential for determining possible actions and outcomes. This essay highlights common deficiencies in our understanding of key concepts such as trust, trustworthiness, cooperation, and assurance in online environments. Empirical evidence from experimental work in computer-mediated environments underscores the promises and perils of overreliance on security and assurance structures as replacements for interpersonal trust. These conceptual distinctions are critical because the future shape of the Internet will depend on whether we build assurance structures to limit and control ambiguity or allow trust to emerge in the presence of risk and uncertainty.

History and structures of telecommunication in pathology, focusing on open access platforms.

BACKGROUND: Telecommunication has matured to a broadly applied tool in diagnostic pathology. TECHNOLOGY AND SYSTEMS: Contemporary with the development of fast electronic communication lines (Integrated digital network services (ISDN), broad band connections, and fibre optics, as well as the digital imaging technology (digital camera), telecommunication in tissue--based diagnosis (telepathology) has matured. Open access (internet) and server--based communication have induced the development of specific medical information platforms, such as iPATH, UICC-TPCC (telepathology consultation centre of the Union International against Cancer), or the Armed Forces Institute of Pathology (AFIP) teleconsultation system. They have been closed, and are subject to be replaced by specific open access forums (Medical Electronic Expert Communication System (MECES) with embedded virtual slide (VS) technology). MECES uses php language, data base driven mySqL architecture, X/L-AMPP infrastructure, and browser friendly W3C conform standards. EXPERIENCES: The server--based medical communication systems (AFIP, iPATH, UICC-TPCC) have been reported to be a useful and easy to handle tool for expert consultation. Correct sampling and evaluation of transmitted still images by experts reported revealed no or only minor differences to the original images and good practice of the involved experts. ß tests with the new generation medical expert consultation systems (MECES) revealed superior results in terms of performance, still image viewing, and system handling, especially as this is closely related to the use of so--called social forums (facebook, youtube, etc.). BENEFITS AND EXPECTATIONS: In addition to the acknowledged advantages of the former established systems (assistance of pathologists working in developing countries, diagnosis confirmation, international information exchange, etc.), the new generation offers additional benefits such as acoustic information transfer, assistance in image screening, VS technology, and teaching in diagnostic sampling, judgement, and verification.
