To the 90ᵗʰ anniversary of V. Rvachev, Academician of the NAS of Ukraine
No full textСтатья посвящена 90-летию со дня рождения выдающегося украинского ученого в области математики, механики и кибернетики, академика НАН Украины Владимира Логвиновича Рвачева. В статье описан жизненный и творческий путь В. Л. Рвачева. Выделены основные результаты научной деятельности В. Л. Рвачева, позволившие сделать существенный рывок в области аналитической идентификации геометрических объектов и решения краевых задач математической физики. Приведены некоторые высказывания В. Л. Рвачева, взятые из его дневников. Представлено краткое описание результатов, полученных В. Л. Рвачевым в последние годы, связанные с построением неархимедовых исчислений и их возможными приложениями в физике дальнего космоса. Представлен список основных публикаций В. Л. Рвачева.The article is devoted to the 90ᵗʰ anniversary of the birth of the outstanding Ukrainian scientist in the field of mathematics,mechanics and cybernetics, Academician of NAS of Ukraine Vladimir L. Rvachev. The article describes the life and creative path of V. Rvachev. The main scientific results of V. Rvachev, that allowed a significant breakthrough in the field of analytical identification of geometric objects and solving boundary value problems of mathematical physics, are discussed. Some statements and quotes of V. Rvachev, taken from his diaries, are listed. A brief description of the results obtained by V. Rvachev during his last years, related to the construction of non-Archimedean calculus and their possible applications in the physics of deep space, is given. A list of the main publications of V. Rvachev is also provided
The place of the Ukrainian technical elite in advancement of world science (on the example of V. L. Rvachev scientific work)
Full text linkРозглянуто науково-педагогічну діяльність видатного українського вченого-математика – Володимира Логвиновича Рвачова. Представлено основні віхи життя академіка, автора теорії R-функцій, атомарних функцій, неархімедового обчислення й автоматизації програмування. Здійснено спробу оцінити його особистий внесок у розвиток української та світової науки.It is considered the scientifically pedagogical activity of the prominent Ukrainian scientist-mathematician – Volodymyr Logvinovich Rvachev. The basic landmarks of life of academician, of author of R-functions theory, of atomic functions, of non-Archimedean calculation and automation of programming are presented. The attempt to estimate his personal contribution into development of Ukrainian and world science is mad
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
