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

Conversion of Blocks in the I3T tool into the ImGui library
No full textTato práce řeší modernizaci nástroje I3T, který nedosahuje požadovaných standardů, kladených na moderní výukové nástroje. Celá modernizace nástroje I3T je řešena v několika závěrečných pracích. Tato konkretní práce se zabývá jednou z částí přípravy náhrady stávajícího nástroje I3T a přechodem do nového uživatelského rozhraní implementováním pomocí knihovny ImGui. To obnáší především návrh nové architektury a zpřehlednění starého kódu. Výstupem práce je dokončená část nástroje I3T odpovidajicí za zobrazení okna Workspace.This thesis resolve modernization of interactive teaching tool of transformations I3T. Unfortunately, the application does not satisfy requirments for modern teaching tool. It is not attractive and intuitive for using. Full modernization of the tool is described in various thesises. The main goal of this work is to prepare transition to new user interface implemented using Dear ImGui library. It involves to design new architecture and make less complex and more readable code. The result of the work is functional Workspace modul
Volume measurement in 3D data
No full textMedical diagnostics using computed tomography or magnetic resonance is a common part of complex medical checkup for a long time. These devices produce vast volumes of data, which must be analyzed by an expert physician. There is a big space for utilising computers to aid medical diagnosis, or visualization. This work aims to measure volume of a specific organ in the human body, like kidneys or spleen. To measure volume of the organ it is necessary to reconstruct the object from three-dimensional data. Reconstruction is based on segmentation of the image data, which separates reconstructed organs from the background. The task of segmentation is specially adapted to this kind of data, which are, from specimen to specimen, characterized by big similarity in common shape, but also by big heterogeneity in tiny details. Deformable models were chosen as a primary tool for the segmentation of three-dimensional volumes. They are also the main topic of this work. Programs measuring volume in medical data exist, but thanks to increasing performance of modern computers it is possible to implement new algorithms, which are not present in today's software tools. The result of this work is a system which segments and measures volume in medical data. We also perform benchmarks, which expose an error of the measurement with..
