ARCHITECTONICS OF SPACE OF HUMAN BEINGIN THE PHILOSOPHY OF N. N. TRUBNIKOV
No full textThis article represents the conception of soviet philosopher Nikolay Trubnikov about space in connection with a category of sense or purpose of human being. The author does the attempt of regular comprehension of some existential themes in Trubnikov’s philosophy by their consideration in context of a spatial problematic. The conclusion about originality and importance of the conception of the philosopher beco
Flame Wrinkles From The Zhdanov-Trubnikov Equation
No full textInternational audienceThe Zhdanov-Trubnikov equation describing wrinkled premixed flames is studied, using pole decomposi tions as starting points. Its one-parameter (−1 0 (over-stabilisation) such analytical solutions can yield accurate flame shapes for 0 < c < 0.6. Open problems are invoked
Regulation of Telecommunications: The Choice Between Market and Regulatory Failures
Get PDFPurpose – The paper examines the main regulatory frameworks of the telecommunications industry through the concept of market failure and analyses how and why the policy often leads to undesirable outcomes that might be considered as regulatory failure.
Methodology/approach/design – The research uses the EU regulatory framework for electronic communications as a base for the analysis of the main policy objectives through the prism of the market failure theory with an eye to the interests of the main market players in the telecommunications markets.
Findings – About any aspect of regulation allows to find ways to create opportunities for some groups of the industry and stifle activity of others. Despite the theory of market failure provides reasonable justifications for regulation of telecommunications markets, it is possible to argue that many of these problems are mainly the consequence of the policy and could be better solved by market mechanisms.
Originality/value – The results of the research allow to look at the problems of telecommunications development and issues of the high level of concentration of the telecommunications markets as regulatory formed problems rather than consequences of the inherited industry’s characteristics
Analysing the Impact of Regulation on Disruptive Innovations: The Case of Wireless Technology
Get PDFThe paper analyses the role of regulation in the suppression of disruptive innovations and shows that this process might be explained by the dependance on the path of joint evolution of regulation and the mainstream technology. Industrial policy in highly regulated industries such as wireless telecommunications is able to support evolution of established technologies and adjust itself to sustaining innovations, while regulatory disconnection impedes disruptive technologies, and the market plays a quite secondary role in this process. We observe more innovations in those parts of telecommunications where regulator is less active, but the core, the physical layer, of the industry is changing in sustaining way of development of the technology. The paper argues that the problem of impediment to disruptive innovations could be alleviated if the crucial resources of the industry were accessible for a number of potential innovators and newcomers. The openness makes easier the appearance of disruptive technologies, and regulation must facilitate it in order to promote opportunities for creative destruction
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
