Point source detection and flux determination with PGWave
No full textOne of the largest uncertainties in the Point Source (PS) studies, at Fermi-LAT energies [1], is the uncertainty in the diffuse background. In general there are two approaches for PS analysis: background-dependent methods, that include modeling of the diffuse background, and background-independent methods. In this work we study PGWave [2], which is one of the background-independent methods, based on wavelet filtering to find significant clusters of gamma rays. PGWave is already used in the Fermi-LAT catalog pipeline for finding candidate sources. We test PGWave, not only for source detection, but especially to estimate the flux without the need of a background model. We use Monte Carlo (MC) simulation to study the accuracy of PS detection and estimation of the flux. We present preliminary results of these MC studies
Climatic dependence of the ecotone between alpine and forest orobiomes in southern Siberia
No full textThis study relates climatic parameters and altitudinal position of the ecotone between forest and alpine orobiomes in southern Siberia. Particular emphasis is laid on the upper forest boundary, or alpine timberline, which marks the lower altitudinal limit of the alpine ecotone. The most indicative climatic parameters, i.e. those which are less variable at the upper forest boundary are, in order of importance: a) duration of the growing season with temperatures exceeding 0 °C, and + 5 °C, b) potential evaporation, c) duration of the sinow-covering period, and, d) mean July air temperature. Less informative parameters are: a) length of the period with temperatures exceeding 10 °C. b) sum of temperatures exceeding 0 °C, 5 °C, and, especially, 10 °C. In semiarid areas, the altitude of the alpine ecotone depends both on heat balance and on dryness, so that the upper forest boundary can be higher on north- than on south-facing slopes. Compared with Arctic timberline, the alpine forest boundary has a longer growing season, and, accordingly, higher temperature totals, but somehow lower mean July temperatures
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
Malyshev Key Factors Affecting the Corporate Tax Levied from Russian Ferrous Metallurgy Corporations to Regional Budgets
No full textIntroduction. The processes of budgetary destabilization in Russia, especially at the regional level, have become protracted, which means that ways to overcome them should be devised. A considerable part of the budgetary problems of the regions is associated with the shortcomings of the tax policies, in particular, with the component related to the taxation of profits of large companies. The purpose of the article is to reveal the factors influencing the volume of corporate tax revenues to regional budgets from Russian ferrous metallurgy corporations, on the basis of the results of the study conducted. Materials and Methods. Data from the Federal Tax Service in the Vologda, Chelyabinsk and Lipetsk Regions and from the Federal State Statistics Service were analyzed, as well as the reports on the financial and production performance and annual reports of such metallurgical corporations as Severstal, MMK, and NLMK. Both the horizontal (dynamic) analysis, showing changes in indicators, and the vertical (weight) analysis, revealing the role of each indicator of financial performance, was performed. Content analysis made it possible to identify the cause-and-effect relationships of changes in the dynamics and structure of indicators. Results. The study has revealed the imperfection of the regulatory and legal instruments currently in force in Russia in relation to large taxpayers. First of all, this concerns the amount of the corporate tax, which was negatively influenced by the peculiarities of the dividend policies of enterprises and the volumes of commercial and administrative expenses. The depreciation of the national currency had a positive impact on the export proceeds, which led to a twofold increase in the total ruble gains of all enterprises under study on average, but not to a corresponding increase in the amount of the corporate tax revenues to the budget. Discussion and Conclusion. Taking into account the identified factors will make it possible to further substantiate measures to increase the efficiency of state’s taxation policies in relation to large business, which is necessary to mobilize corporate tax revenues to the country's budget system and to develop its territories. The results of this study will be useful for public authorities responsible for making decisions in the field of interaction with business entities
