Eventology versus contemporary theories of uncertainty
Get PDFThe development of probability theory together with the Bayesian approach in the three last centuries is caused by two factors: the variability of the physical phenomena and partial ignorance about them. As now it is standard to believe [Dubois, 2007], the nature of these key factors is so various, that their descriptions are required special uncertainty theories, which differ from the probability theory and the Bayesian credo, and provide a better account of the various facets of uncertainty by putting together probabilistic and set-valued representations of information to catch a distinction between variability and ignorance. Eventology [Vorobyev, 2007], a new direction of probability theory and philosophy, offers the original event approach to the description of variability and ignorance, entering an agent, together with his/her beliefs, directly in the frameworks of scientific research in the form of eventological distribution of his/her own events. This allows eventology, by putting together probabilistic and set-event representation of information and philosophical concept of event as co-being [Bakhtin, 1920], to provide a unified strong account of various aspects of uncertainty catching distinction between variability and ignorance and opening an opportunity to define imprecise probability as a probability of imprecise event in the mathematical frameworks of Kolmogorov's probability theory [Kolmogorov, 1933].uncertainty, probability, event, co-being, eventology, imprecise event
“Autobiography of professor Nikolay Iosifovich Vorobyev”
Get PDFThe publication is a commentary and the text of the handwritten autobiography of N.I. Vorobyev. The document is introduced into scholarly discourse for the first time. The undertaken analysis of the text allowed us to identify new facts from the life and work of the researcher and to grasp their context. The document is dated March 2, 1947 and was written by the scholar during his work at Kazan State University. N.I. Vorobyev lists in detail the facts about his parents, the process of receiving an education, the beginning of his teaching and research work. He reveals the evolution of his own academic interests, from geography to ethnography, and highlights the author’s scholarly papers that are of significance from his point of view. The document mentions N.I. Vorobyev’s research work in the Far East dedicated to the study of the life of the Nanai (the Golds) and in the Mari ASSR – limnological studies of lakes. The researcher emphasises his work on methodological support of teachers. A separate chapter of the autobiography contains a description of the academic’s participation in the work of various public scholarly organisations. N.I. Vorobyev focuses on the important aspects of his life that correspond to the spirit of those times. This is the recognition of his political unconsciousness in the first years of the Soviet power, service in the Red Army as a private soldier. The autobiography of N.I. Vorobyev is a valuable, informative source. It shows not only the significance of individual milestones in his life and work for the scholar himself, but also reveals the distinctive features of the Soviet era, which formed the conditions for work for the entire academic community
Book review “N.I. Vorobyev. Kazan Tatars. Kazan: Tatgosizdat, 1953”
Get PDFThe work under review is devoted to the characteristics of the material culture of the Kazan Tatars of the late 19th – early 20th centuries. The author set himself the task to identify the main elements of the Kazan Tatars’ material culture, trace the history of its formation, and analyse its characteristic territorial and class differences. The work is based on the monograph of the same author, Material Culture of the Kazan Tatars, published in 1930. Since that time, the author has accumulated new material, critically revised previous conclusions, and essentially produced a new work (cit.: Smirnov A.P. (1954) N.I. Vorobyev. The Kazan Tatars. Tatgosizdat, Kazan, 1953. Sovetskaya etnografiya [Soviet Ethnography]. No. 3: 168–172. (In Russ.))
The methods of Vorobyev and Lanczos
No full textAbstractThis paper deals with the method of moments of Vorobyev, which is a particular case of Galerkin's method. This method is generalized in different ways, and some of its properties are studied in detail. As an application, it is showed that the Lanczos method for solving systems of linear equations can be derived from it and that some generalizations could be obtained
The Artist’s Mission During the Russo-Turkish War of 1828–1829: Documentary Landscapes by M.N. Vorobyev
Get PDFThe artist Maxim Nikiforovich Vorobyev (1787–1855) possessed a unique gift for combining his creative work with public service, dedicating himself fully to fulfilling tasks and the mission of serving his homeland. Within the scope of the research article, the author examines his role in the military expedition of 1828–1829, where M.N. Vorobyev not only created sketches and paintings at the behest of Emperor Nicholas I and his court but also actively participated in visualizing military and technological innovations. That military expedition became the foundation for several significant works by the artist, including The Seashore Near Varna (1829), View of the Military Telegraph Near Varna (1829), and The Explosion of Varna (1828), which are rarely mentioned in contemporary literature for various reasons. In 1828–1829, as an experienced artist who had participated in multiple military campaigns and diplomatic expeditions, he was seconded to the staff of the Black Sea Fleet and participated in the Russo-Turkish War as an artist and chronicler. His visual reports and sketches often contained hidden information understood only by a narrow circle of high-ranking officials. Those works served as encrypted messages where artistic value intertwined with diplomatic significance. In this study, the author proposes reconstructing the historical context to deepen understanding of the iconography of M.N. Vorobyev’s series of landscape paintings, created as a visual chronicle of the events of the Russo-Turkish War of 1828–1829
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
