Planar minimal surfaces with polynomial growth in the Sp(4, R)-symmetric space
Get PDFWe study the asymptotic geometry of a family of conformally planar minimal surfaces with polynomial growth in the \Sp(4,\R)-symmetric space. We describe a homeomorphism between the "Hitchin component" of wild \Sp(4,\R)-Higgs bundles over \CP^1 with a single pole at infinity and a component of maximal surfaces with light-like polygonal boundary in \h^{2,2}. Moreover, we identify those surfaces with convex embeddings into the Grassmannian of symplectic planes of . We show, in addition, that our planar maximal surfaces are the local limits of equivariant maximal surfaces in \h^{2,2} associated to \Sp(4,\R)-Hitchin representations along rays of holomorphic quartic differentials
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

No full textVariations 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
Reigniting the Many Voices of a Communal Bison Hunt in Virtual Reality
Get PDFA major challenge to language and culture revitalization is geographic dispersal, as over 60% of Native Americans do not live on their language communities’ reservations. Immersive environments in Virtual Reality (VR) bridge this distance for those Native Americans who can’t readily sit down with a tribal elder. We are grassroots language activists who are combining VR technology with GIS data, film, and 3D imaging to create rich, interactive experiences for language, history, and culture teachings. Our pilot project focuses on buffalo jumps and the buffalo culture. Our culturally relevant software centers on a sacred site in Montana, the Madison Buffalo Jump. Now it is a popular recreational park. For millennia, this was a shared hunting ground for dozens of Indigenous nations. Before the horse and rifle, buffalo jumps served as the center of tribal nourishment. Though communal bison hunts are not practiced in this form anymore, there is great reverence for these sacred sites by all tribes in Montana. Each tribe has a unique perspective on communal bison hunts, and our software demonstrates this with the support of our partners. The VR experience shares culture teachings, traditional environmental knowledge, and Indigenous botanical science from various tribal nations of Montana in multilingual scenes. This presentation will demonstrate how we are using advanced 3D gaming technology, consumer mobile devices, and the voices of tribal elders to recreate an exhilarating communal bison hunt in Virtual Reality. We will also outline our non-exploitive data-collection process under consideration of the 6 R’s: Respect, Relevance, Relationality, Responsibility, Reciprocity, and Representation. Tribal communities shaped our VR software to foster knowledge sovereignty and ownership by our collaborators. We believe this is just the first step in delivering language and cultural material on a compelling and technologically advanced platform. Our VR experience not only contributes to the respectful preservation of American Indian cultures, languages, and oral histories, but also reintroduces tribal histories, knowledge, and perspectives to the public, and helps preservation efforts at the Madison Buffalo Jump State Park
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
