Evaluating The Quality, Utility And Reliability of Information In Uveitis Videos Shared On YouTube

Background: The aim of this study was to analyze the quality of videos on YouTube as educational resources about uveitis.Methods: An online YouTube search was performed using the keyword ‘‘uveitis’’. Total view counts, duration of videos, publishing dates, likes and dislikes, numbers of comments, and source of videos were recorded. Educational quality and accuracy of the video content were evaluated using the DISCERN score, Global Quality Score (GQS), Journal of the American Medical Association (JAMA) score. Video popularity was also evaluated using the video power index (VPI) score. All videos were classified according to publishers and types of categories.Results: From among the 200 videos analyzed, 94 were included. The mean DISCERN score was 38.5 ± 13.2 (poor), the mean JAMA score was 1.8 ± 0.6 (fair), and the GQS was 2.5 ± 0.9 (fair). There were positive correlations between the three checklist (p < .001). VPI was not correlated with each score (p >.05). The most common upload sources were ophthalmologist (24.4%) and YouTube channel (20.2%). Regarding content, 47 videos (50%) medical education, 26 videos (27.6%) patient education, 16 videos (17%) patient experience, 5 videos (5.3%) surgical procedures in patient with uveitis. While the most popular videos were uploaded by doctors other than ophthalmologists, the videos uploaded by academic institutions and associations were found to be higher educational quality and reliability scores. Conclusions: Uveitis videos on YouTube are poor quality and reliability and are not adequately educational for patients. Therefore, the physicians must be aware of the limitations of YouTube and ensure the flow of correct medical information to patients.

In contemporary fiction, modesty comes to reflect the limits of human and critical agency in the Anthropocene. The dilemma of the Anthropocene is, in large part, a cosmological one, for it challenges our total view of the universe and humanity’s place in it. My readings of fiction have highlighted various kinds of modest relations and the differences they make, whether it be J. M. Coetzee’s belief in the power of modesty rhetoric to disrupt the polarized logic of political life or Zadie Smith’s insistence on how readerly modesty transforms our understanding of the relation between critic and work. Entailed in each individual argument for modesty is an account of how a reorientation of attitude transforms and makes possible interventions, resistances, and projects that otherwise might have remained untaken. Each novel offers a kind of testimony to the power of temperament for dealing with the myriad of troubles that humans must confront today. To put it in these terms is to emphasize in a new way the chiasmic relationship between the specific temperament called modesty, which is the subject of the book, and power of a modest temperament as a concept for criticism....

Who Cares? ―The COVID-19 Pandemic, Global Heating and the Future of Humanity1

The COVID-19 pandemic has engendered unprecedented drastic and costly measures to obviate the threat. Will something similar happen in relation to global heating? No, this is not likely. Mainly this has to do with a difference in the nature of collective action. Nation states protect their respective populations against the virus. With regard to global heating, we are facing the tragedy of the commons. No global government assumes responsibility for our common future. However, there may be another and further explanation lurking behind political inaction: many people, including our politicians, think that it does not matter if humanity goes extinct. It does matter, however. Strangely enough, the view that it matters is questioned by many important philosophers in the past and in the present, and it is hence controversial. Yet, it should be our common-sense stance to the problem. It is of the utmost importance that there will be sentient happy life on the globe for an indefinite time. Theoretically speaking, in order to recognize this, we need to accept some “total” view, implying what has been called the repugnant conclusion. Practically speaking, we should go to great length to rescue our human civilisation, even if this means that, for a while, we must endure all sorts of hardships such as a global enlightened despotism, or worse—a situation of life boat ethics.

Big Data Analysis of a Dedicated YouTube Channel as an Open Educational Resource in Hand Surgery

Background: Educationally designed videos have the advantage of explaining difficult concepts via graphic diagrams and dynamic illustrations. The benefits of videos will be enhanced if videos are well-designed, concise, explore scientifically correct content, and have a clear presentation.Aims: Video as an open educational resource (OER) is the cornerstone for online learning. YouTube has been widely used as a distribution platform for OER. The aim of this study was to evaluate the engagement of hand surgery videos on a dedicated education channel on YouTube.Methods: The senior author has been utilizing a YouTube channel dedicated to the education of clinicians in Hand Surgery, surgical education, and management since 2008. The degree of engagement was evaluated using YouTube Analytics, providing up-to-date metrics and reports.Results: Since 2008, there have been 6521 subscribers with 1,360,680 views, a total view time of 35,033 h and an average view time of 1.72 min. The channel views averaged 1000 views per day. There were 4,324,724 impressions with a 7.32% click-through rate, with the United States of America accounting for 23.5% of the audience. YouTube search accounted for 33.3% of the traffic source and suggested videos by others were 19.4%, and external links were 19%. Playback location was through mobile devices in 76.7%, while 16% was through the computer. The two popular playlists were “flaps in hand surgery” (50.2%) and “basic hand surgery workshop” (21.9%). Sharing by WhatsApp was most popular (27.9%) in embedded websites and apps. Overall there were 488 comments on the channel.Conclusion: This paper confirms the phenomenon of micro-learning by online learners. It is recommended that educational videos as OER should be confined to 2 min, made compatible for the mobile device, and be optimized for sharing on social media. These can be used as resources for blended learning, allowing better utilization of time for deliberate practice in surgical training.

Comparing the Visual Perception According to the Performance Using the Eye-Tracking Technology in High-Fidelity Simulation Settings

Introduction: We used eye-tracking technology to explore the visual perception of clinicians during a high-fidelity simulation scenario. We hypothesized that physicians who were able to successfully manage a critical situation would have a different visual focus compared to those who failed. Methods: A convenience sample of 18 first-year emergency medicine residents were enrolled voluntarily to participate in a high-fidelity scenario involving a patient in shock with a 3rd degree atrioventricular block. Their performance was rated as pass or fail and depended on the proper use of the pacing unit. Participants were wearing pre-calibrated eye-tracking glasses throughout the 9-min scenario and infrared (IR) markers installed in the simulator were used to define various Areas of Interest (AOI). Total View Duration (TVD) and Time to First Fixation (TFF) by the participants were recorded for each AOI and the results were used to produce heat maps. Results: Twelve residents succeeded while six failed the scenario. The TVD for the AOI containing the pacing unit was significantly shorter (median [quartile]) for those who succeeded compared to the ones who failed (42 [31–52] sec vs. 70 [61–90] sec, p = 0.0097). The TFF for the AOI containing the ECG and vital signs monitor was also shorter for the participants who succeeded than for those who failed (22 [6–28] sec vs. 30 [27–77] sec, p = 0.0182). Discussion: There seemed to be a connection between the gaze pattern of residents in a high-fidelity bradycardia simulation and their performance. The participants who succeeded looked at the monitor earlier (diagnosis). They also spent less time fixating the pacing unit, using it promptly to address the bradycardia. This study suggests that eye-tracking technology could be used to explore how visual perception, a key information-gathering element, is tied to decision-making and clinical performance.

Viewing Trends and Users’ Perceptions of the Effect of Sleep-Aiding Music on YouTube: Quantification and Thematic Content Analysis

Background Sleep plays an essential role in the psychological and physiological functioning of humans. A report from the Centers for Disease Control and Prevention (CDC) found that sleep duration was significantly reduced among US adults in 2012 compared to 1985. Studies have described a significant association between listening to soothing music and an improvement in sleep quality and sleep duration. YouTube is a platform where users can access sleep-aiding music videos. No literature exists pertaining to the use of sleep-aiding music on YouTube. Objective This study aimed to examine the patterns of viewing sleep-aiding music videos on YouTube. We also performed a content analysis of the comments left on sleep-aiding music video posts, to describe the perception of users regarding the effects of these music videos on their sleep quality. Methods We searched for sleep-aiding music videos published on YouTube between January 1, 2012, and December 31, 2017. We sorted videos by view number (highest to lowest) and used a targeted sampling approach to select eligible videos for qualitative content analysis. To perform the content analysis, we imported comments into a mixed-method analytical software. We summarized variables including total views, likes, dislikes, play duration, and age of published music videos. All descriptive statistics were completed with SAS statistical software. Results We found a total of 238 sleep-aiding music videos on YouTube that met the inclusion criteria. The total view count was 1,467,747,018 and the total playtime was 84,252 minutes. The median play length was 186 minutes (IQR 122 to 480 minutes) and the like to dislike ratio was approximately 9 to 1. In total, 135 (56.7%) videos had over 1 million views, and 124 (52.1%) of the published sleep-aiding music videos had stayed active for 1 to 2 years. Overall, 4023 comments were extracted from 20 selected sleep-aiding music videos. Five overarching themes emerged in the reviewed comments, including viewers experiencing a sleep problem, perspective on the positive impact of the sleep-aiding music videos, no effect of the sleep-aiding music videos, time to initiation of sleep or sleep duration, and location of viewers. The overall κ statistic for the codes was 0.87 (range 0.85-0.96). Conclusions This is the first study to examine the patterns of viewing sleep-aiding music videos on YouTube. We observed a substantial increase in the number of people using sleep-aiding music videos, with a wide variation in viewer location. This study supports the hypothesis that listening to soothing music has a positive impact on sleep habits.

Foreshadowing the Future of Capitalism: Surveillance Technology and Digital Realism in Xu Bing’s Dragonfly Eyes

How has the development of surveillance technology and its normalized intervention into our social structures and daily lives impact our imagination of the future? Does the “total view” of the intense yet impassive gaze of surveillance cameras, combined with the mediated intimacy of social media videos, foreshadow deeper social alienation or the fulfillment of individual desire? In order to address such questions, I take the Chinese artist Xu Bing and his team’s film Dragonfly Eyes (Qingting zhi yan, 2017) and its surrounding media culture as a case study to demonstrate how surveillance footage and various modes of cinematic ontology, digital realism, and temporality work in a contemporary socio-political-medial context. Composed by Xu and a group of collaborators, Dragonfly Eyes is the only existing feature-length fiction film constructed completely from surveillance footage. As a highly reflexive film, Dragonfly epitomizes and embodies the precarious potentials of the digital future of capitalism, both invigorating and bleak, expressive and corrupt.

Why Derek Parfit had reasons to accept the Repugnant Conclusion

Total views imply what Derek Parfit has called ‘the repugnant conclusion’. There are several strategies aimed at debunking the intuition that this implication is repugnant. In particular, it goes away when we consider the principle of unrestricted instantiation, according to which any instantiation of the repugnant conclusion must appear repugnant if we should be warranted in relying on it as evidence against total theories. However, there are instantiations of the conclusion where it doesn't seem to be at all repugnant. Hence there is nothing repugnant about the repugnant conclusion as such. The faults with total views have nothing to do with large numbers or with the conclusion as such. It is possible, if you like, to correct these putative faults even if you adopt some total view (different from utilitarianism).
