Item Data from: Exploring Video Abstracts in Science Journals(2014-03-05) Spicer, Scott; spic0016@umn.edu; Spicer, ScottData from a study exploring the emerging role of video abstracts in science scholarship, with implications for library based publishers and other services.Item Demand-Side Approaches to Improving Global Food Sustainability(2015-08) Reich, AlexanderHumanity faces the grand challenge of doubling its food supply by 2050 while reducing agriculture's already substantial impact on the environment. Supply-side approaches such as sustainable intensification may not be able to achieve this goal alone without significant efforts to reduce food waste and the consumption of animal products. This thesis presents three efforts to learn and educate about these demand-side strategies. To inform policymakers about the state of the science of food loss and waste in the United States, we created a technical issue brief. Using the principles of behavioral economics and psychology as applied to public policy, we transformed the issue brief into an accessible format, online video, to reach ~650,000 viewers. Finally, we conducted exploratory research into the potential of a global carbon tax to mitigate greenhouse gas emissions from animal protein today and in 2050, finding little evidence of its efficacy.Item Exploring learning during a business ethics simulation.(2011-04) Revoir, Richard LeonardThe purpose of this study was to explore a simulation incorporating online collaborative technologies in a business ethics course to examine whether it affects student learning. A qualitative case study method of inquiry was used to develop an in-depth description and analysis of student learning during a business ethics simulation using data collected through a questionnaire, student ratings of the simulation, focus groups, and a review of videos by the researcher. The results of this study provide insight into themes that may affect students' moral sensitivity and judgment. Three key themes emerged during data analysis: 1) working in groups, 2) watching YouTube videos, and 3) experiencing less nervousness. Working in groups appeared to affect moral sensitivity because the students were exposed to more perspectives from classmates who helped them interpret the case simulation and identify ethical issues. The students reported being able to rewind and review the YouTube videos was helpful to learning. The videos also provided more perspectives and multiple approaches for reasoning which may have affected students' moral sensitivity in their effort to interpret the simulations and identify ethical issues. Students reported being less nervous while recording their YouTube video than if they had to complete the assignment in-class in front of their peers. In addition, students came to class with their YouTube video completed, they had time in class to reflect on other students' performances during class time, rather than focus on their impending performance. The findings of this study add to the literature in the area of business ethics by describing how the integration of technology for ethical simulations may affect student learning. With the three themes identified, the results of this study have implications for college instructors who are teaching business ethics courses.Item Exploring Video Abstracts in Science Journals: An Overview and Case Study(Journal of Librarianship and Scholarly Communication, 2014-03-02) Spicer, ScottINTRODUCTION The video abstract has emerged in recent years as a new way of communicating the results of scholarly enquiry. For library-based journal publishers who want to support multimodal scholarship, it is useful to understand the potential benefit and impact of incorporating video abstracts into their publications. This paper provides an overview of the growth of video abstracts in science scholarship, and presents a single journal case study that compares the use and potential impact of video abstracts hosted on both YouTube and on a journal’s own website. METHODS For the case study, video abstract usage data for the New Journal of Physics (NJP) was gathered from both YouTube and the NJP native platform and then correlated using a Spearman rank correlation coefficient test to analyze viewing usage. Viewership data from both platforms was also correlated with article usage counts using Spearman to study the relationship between article usage and corresponding video abstract usage. RESULTS Users predominantly accessed the journal’s hosted video abstracts instead of the abstracts posted on YouTube. However, there was a moderate positive correlation comparing view counts of the same video abstracts across both platforms, suggesting proportionate use of both platforms. In addition, the top 25 and 100 read articles had a significantly higher presence of video abstracts than articles overall in the data set, although a specific reason for that relationship cannot be identified. DISCUSSION & CONCLUSION Video abstracts are a natural evolution of science communication into multimodal environments. Publishing trends will likely continue to grow gradually, with appreciation for non-traditional scholarship (multimodal scholarship) and new measures for assessing impact (altmetrics) potentially encouraging greater adoption. Librarybased journal publishers should consider investing in software that offers dynamic media integration, offering the video abstract option to their authors, and leveraging YouTube to further raise the visibility of their authors’ research articles and publication. Library-based publishers should have some expectation that the video abstracts will be viewed relatively proportionally across platforms (i.e. a video abstract that receives a higher or lower view count on the journal’s website is moderately more likely to also receive a higher or lower view count on YouTube), with the majority of total views (for all videos) coming from the journal’s website. Subject and media librarians should become more aware of these emerging practices to support the video abstract publication and creation needs of their research communities.Item The Me in Media: A functionalist approach to examining motives to produce within the public space of YouTube.(2010-03) Jones, Julie MarieOften news organizations perceive social media platforms, such as YouTube, as a distribution tool for their content and the users of these sites as audiences yet to be acquired. From this perspective, the value within the site is a benefit to the organization but only if they retain control of their content. When they are not in control of the content, practices within these sites are considered a threat in terms of thievery (piracy of their content) or time displaced from consuming mass media programming. From the other side of this argument, media scholars contend that social media platforms are tools of self-expression that return a benefit to a public good, even when that expression is directly built upon content produced by mass media. Deliberately, this work took the stance that understanding the intersection between journalistic function and social media practices must consider the user first. YouTube and its users was chosen for this work since it is the largest social media site and uses video content as its main exchange. A conceptual model that locates three spaces, not two, of YouTube is presented: an interpersonal space, a public space, and a commercial space. Two studies were undertaken: study one was a content analysis of video responses to a question posed by a popular YouTuber on why they "Tubed?" Study two surveyed YouTubers directly on their motive changes and self-concept changes since they had first began to produce for the site. However, the main question posed was drawn from findings from the first study. In study one, the YouTube space was mainly spoken about as community. In study two, producer/users (creators) were significantly more likely than users (watchers) to perceive YouTube as a community. However, items drawn from the Sense of Community Index and Brief Sense of Community Index scales did not correlate as they have for geographical communities. Findings from both studies place theories frequently used to examine new media uses in a new light. Although uses and gratifications is one of the tried-and-true theories used to explain motivations to use new media sources, YouTubers' produce motives were more diverse and complex than their watch motives. This suggests that U & G might be helpful in understanding motives consistent with being an audience, but is not as helpful in understanding motives to produce. Study two extended this inquiry by asking YouTubers how their motives and their self-concept had changed since beginning their YouTube channel. While there were no quantitative variables that influenced motive change, the elaborations provided by the respondents on how they changed suggest that migrations in social media sites, instead of motives changes, should be considered for future work. As to self-concept changes, quantitative analysis revealed that producer/users whose videos had generated discussion were significantly more likely to see themselves differently. Both quantitative and qualitative findings are presented and discussed. At the heart of it, though, this dissertation highlights the need to understand exactly what online cohorts - such as YouTube producer/users - mean when they use the term "community" and how that construct shares similarities to and differs from geographic communities.Item Measurement and Sentiment Analysis of YouTube Video Comments(2022-11) Sui, XinyuAccording to the latest video consumption statistics in 2022, 92.7 percent of global Internet users worldwide visits online video-sharing platforms, such as YouTube and TikTok, every week. These users share their videos and exchange image/text comments to establish crucial social network interactions. Based on the existing research, users’ likes and comments are evidence commonly used to quantify the popularity of videos and social media creators. However, it remains largely unclear if the sentiment of comments, e.g., negative comments, will also affect the video or video creators’ popularity. In this thesis, we take initial steps to explore YouTube video comments via sentiment analysis. We present an in-depth measurement study of commenting and user’s comment behaviors on a sample of more than 7 million comments on 4 million YouTube videos. Our measurement indicates that Music and Gaming videos attract more feedback and are more likely to be affected by the sentiment of comments. To better understand this, we utilize three popular machine learning models and two deep learning models to analyze the sentiment of video comments. Unlike Twitter and Facebook-based research, our study proves that negative comments do not significantly impact the popularity of YouTube videos. This means the online video-sharing platforms are more robust against unhealthy comments or rumors.Item Online and In the Spotlight: A Critical Analysis of The Beauty Vlogger(2018-08) Weinzimmer, LaurenThis dissertation analyzes the beauty vlogger, who I define for purposes of this project as an individual who produces beauty content across multiple social media platforms as her full-time job. Through textual and discourse analysis, personal observation, and interviews with content creators, I theorize the beauty vlogger through the multiple identities that she simultaneously embodies – those of the female entrepreneurial laborer, the public persona, and the social media “influencer.” Not only does this dissertation critically interrogate the beauty vlogger as she exists within the contemporary post-Fordist and neoliberal capitalist context, but it also historicizes the figure of the beauty vlogger by looking to other modes of gendered, raced, and classed entrepreneurialism within and around the beauty industry over the course of the twentieth century. In the current moment, the beauty vlogger exists within a highly commercialized environment, both through her engagement with online video and social media platforms like YouTube, Facebook, Instagram, Twitter, and Snapchat which monetize the content she creates and through her positionality vis-à-vis the traditional beauty industry. In her role as a public persona and social media influencer who tests and reviews beauty products, the beauty vlogger functions as a critical part of emergent marketing and advertising strategies that capitalize on the relationship the beauty vlogger fosters with her audience. Increasingly, this content has materialized into formalized, paid partnerships between the beauty vlogger and beauty brands, which provides the beauty vlogger with additional revenue streams. The lifestyle that the beauty vlogger promotes online as an entrepreneur, a public persona, and an influencer, is one which others aspire to attain, but it is important to remember the curated nature of the beauty vlogger’s online identity. In this dissertation, I render visible the beauty vlogger’s hidden labor that produces and mitigates her seemingly glamorous lifestyle.
