Similarity Assessments, Spacetime, and the Gravitational Field: What Does the Metric Tensor Represent in General Relativity?
Get PDFIn this paper I explore the dialectics underlying the choice between a geometrical and a field interpretation of the metric tensor gab in general relativity. My aim is to examine the role of a specific type of reasoning process (which I call ‘similarity-based reasoning’) in interpreting gab. In recent years, philosophers of physics have claimed that the problem of choosing between the two interpretations in question is somehow insubstantial. This appearance of insubstantiality, I contend, stems from a basic form of underdetermination that affects the concepts of spacetime and physical field in the context of general relativity
David Rey Interview
No full textThis oral history interview was conducted by Gregory Peek as part of The Joe Anthony Project. Summary of the interview by Gregory Peek: "David Rey is a San Antonio musician and multi-instrumentalist who has performed in a several hard rock and heavy metal bands over the years. David’s father served in the military which is what brought him to San Antonio 1987 where he encountered Joe Anthony on KISS-FM. He discusses attending concerts in San Antonio including his first in 1987 when Def Leppard play with Tesla at HemisFair arena. Also references rock clubs like Sneakers and the Showcase. David joined the San Antonio Jaycees which was a social organization that hosted La Semana Allegre during Fiesta. David talks about the change in rock genre and formats from the glam rock and hair metal of the late 1980s to grunge and alternative rock of the 1990s. This was felt both on MTV and on the radio, including 99.5 KISS-FM. Talks about the difficulty of local San Antonio bands who were more firmly rooted in traditional rock sound of the 80s to make headway during the 1990s. One exception was a band called Petting Zoo who played in Austin and the early incarnations of the SXSW Music Festival. Rey remembers they had a Jane’s Addiction type sound, which kept with the emerging tastes of the decade. Talks about how there was and continues to be a very strong tradition of local musicianship in San Antonio whose tastes were informed and influence by Joe Anthony and KISS-FM.
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
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

koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
