“Modern Day Presidential:" Donald Trump and American Politics in the Age of Twitter
No full textThe increasing power of social media over American news and politics is difficult to ignore thanks to the visibility of President Trump’s tweets both on online and traditional media. This paper seeks to better understand the strategy behind Donald Trump’s use of Twitter both as a candidate and during his first year as president. Through a careful study of his tweets and their ability to take advantage of the specific user makeup on Twitter and the choice of mainstream media to often echo his tweets in their coverage, a consistent strategy emerges based on a combination of traditional advertising practice and radicalist discourse that continues to reshape the American political landscape today
The Promise and Perils of Asynchronous Learning: How Faculty, Students, and Administrators can Collaboratively Increase Retention and Satisfaction in the Online Classroom.
No full textThis paper explores some of the major challenges faced by faculty, students, administrators, and support staff in retaining online students, and doing so while earning high marks for the quality of each course. A number of strategies are explored beginning with the need to carefully consider effective mixes of technology, structure, and content in the classroom environment. With an emphasis on social presence and careful consideration of how students use technology to access the class learning management system (LMS), the paper offers a variety of options to build classroom spaces that foster a sense of community and collaboration. Thereafter the paper addresses best practices to turn well‐ considered design elements into a classroom experience which addresses issues related to retention, achieving learning outcomes, and ensuring students and faculty invest in the learning process from day one. By addressing concerns shared by the major actors in the field of online education, realistic best practices can be identified to help ensure online learning achieves, if not exceeds, retention and satisfaction levels seen from brick‐and‐mortar classrooms
Visualizing the Limits of Democracy in the Silence of the Cold War: The Photography of Life Magazine and the Unraveling of the American Century
No full textThis volume emanates from a commemorative act—the University’s tenth Symposium on Democracy, founded in 2000 as a living memorial to the four students who lost their lives and as an enduring dedication to scholarship that seeks to prevent violence and promote democratic values and civil discourse. The work in this collection pursues historical meaning that holds relevance both for a particular community and speaks indelibly to the entire human community
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Ending the Silence: Using New Media Technologies to Overcome Alienation in the Virtual Classroom
No full textStudents as well as faculty often feel alienated from their peers and the general functioning of online courses, shaped by expectations of in-person teaching etched into participants by a culture holding rigid expectations of proper classroom dynamics. Even with blended classrooms, while they allow relationships between participants to be grounded in physical space, they do not avoid the alienating potential of transferring those relationships online. However, as much as technology and the expectations associated with it has helped birth the “distance” in distance learning, it can also offer a solution. Regular and dynamic discussions, small peer groups, the use of visual media to spur discussion, as well as multiple channels of feedback, from announcements to Twitter, YouTube and other digital means, creates presence through technology. The result blends the intimacy the traditional classroom offers with the advantages of virtual communication. Course structures that provide an easy means to keep up on expectations and are built into the design are also critical. This creates a more dynamic and active online learning experience critical in building community, that feeling among students they are not just individuals working towards the completion of the course, but part of a greater whole. This presentation will cover techniques gathered from researchers and personal experience to build community in the online classroom, addressing longstanding criticisms of distance learning and best practices to improve the student learning experience and faculty satisfaction in blended or wholly online courses
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
