CT radiomic features for canine primary lung tumors
No full textDatasets used for statistical analyses from the 65 dogs included in the study are available for review. Data include clinical data, CT review, histopathologic review, and first order radiomic features extracted from postcontrast thoracic CT images.Quantitative analysis of computed tomography (CT) radiomic features is an indirect measure of tumor heterogeneity, which has been associated with prognosis in human lung carcinoma. Canine lung tumors share similar features to human lung tumors and may serve as a model in which to investigate the utility of radiomic features in differentiating tumor type and prognostication. The purpose of this study was to correlate first-order radiomic features from canine primary lung tumors to histopathologic characteristics and outcome. Sixty-seven tumors from 65 dogs were evaluated in this study.University of Minnesota CVM Resident and Graduate Student Research GrantsWolf-Ringwall, Amber; Rendahl, Aaron; Seelig, Davis; Ober, Chris; Able, Hannah; Wilke, Chris; Lawrence, Jessica.

Governmentality as Reflexive Method: Excavating the Politics of Legal Research
Get PDFThis chapter argues that in addition to examining the politics of method in terms of how they impact our results we ought also to excavate, evaluate, and emphasize the background assumptions and discursive commitments that produce these results and cause us to ask the questions we do, in the way that we do. Researchers should be conscious of the impact that our ontological, epistemological, political, and normative commitments have on our work and maintain an awareness of the fact that these assumptions are contingent, constructed, and politically significant. There are many different means of attempting to excavate the framing narratives that lurk in the background of 'method' and to attempt to piece together their impact on the politics of (legal) research. This piece presents one such means, offering the 'toolbox' of post-Foucauldian governmentality studies as a useful reflexive starting point for legal academics seeking to uncover how methods serve to produce truths regarding the social world in line with their background assumptions

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
