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
EVOLUTION OF OUTSOURCING RELATIONS IN THE OIL & GAS INDUSTRY OF RUSSIA
Get PDFPurpose: the purpose of this article is to study the evolution of oil&gas service outsourcing, to determine trends and factors that define these trends. The article also tests the methodology of “five forces of outsourcing” model formulated by the author.Methods: a number of factors, which constitute the “five forces of outsourcing” model, proposed by the author, influences outsourcing. The elements of the model are transaction costs, competitive advantages, trust and commitment, level of economic development and the “sourcing cycle”. The article uses extensive amount of company data and market research, contains assessment of the market volume and prospects of its growth.Results: oil & gas services are the most dynamic type of outsourcing in the oil & gas industry. The article analyses the evolution of oil & gas services outsourcing for the past 20 years through the lenses of the “five forces” methodology. This type of outsourcing first emerged when the Russian economy turned to market economy. It started from the “ground zero” point, evolved, matured and finally became an indispensable part of the oil & gas industry nowadays. At the same time the oil&gas industry reimagined its value chain, having concentrated on its competitive advantages and transferred service business processes to outsourcing providers. The market of oil & gas services outsourcing passed the test when an attempt to create a state monopoly in this field failed due to the maturity of the market.Conclusions and relevance: the task of increasing eficiency of the oil & gas industry in Russia is paramount especially taking into account the decrease in oil prices. Outsourcing is, undoubtedly, one of the means of achieving such eficiency. Its volumes will keep growing. Yet some companies will continue to test the effectiveness of insourcing operations. The analysis also confirmes the validity of the “five forces” methodology as well as the “sourcing cycle” theory
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
О РОЛИ И ПЕРСПЕКТИВАХ АУТСОРСИНГА В ЭКОНОМИКЕ РОССИИ
Get PDFThe author defines outsourcing not only as a business-tool, but also as one of the most important indicators of the health of the national economy and its competitiveness. Methodology to define the volume of outsourcing in the economy proposed by the author is new to the Russian economic science. By using a range of econometrics of personal design - namely methods of «statistics», «industries» and «outsourcing» (explained hereinafter) the author defines the share of outsourcing as 19% of GDP. At the same time, the author proves that the current volume of outsourcing is insufficient to secure stable growth of the economy. Industrial behemoths and state owned companies - so called national champions - are weakening, not strengthening the competitiveness of the Russian economy with their size. Because of the very overconcentration in the Russian economy, the share of small and medium enterprises is too small. The number of workers hired by SMEs is also less than in other comparable economies. The insufficient share of outsourcing also to the lack of innovations, because innovation breeds not inside large state owned corporations but amongst entrepreneurs. In the end of the article summarizes factors that will contribute or otherwise hamper the development of outsourcing in the Russian economy, influencing its competitiveness worldwide.Автор статьи определяет аутсорсинг не только как предпринимательский инструмент, но и как один из важнейших показателей развития экономики страны и ее конкурентоспособности. Методика оценки объема аутсорсинга в экономике определяет новизну исследования в практике российской экономической науки. На основе различных авторских эконометрических методов доля аутсорсинга в ВВП России оценивается на уровне 19%. Автор доказывает, что данный уровень аутсорсинга в Российской экономике недостаточен для ее стабильного развития. Промышленные конгломераты и госкомпании ослабляют, а не усиливают конкурентоспособность страны за счет своих размеров. Именно из-за сверхконцентрации капитала в экономике России в ней слишком мала доля малых и средних предприятий, и в них занято гораздо меньше работников по сравнению с другими странами. Недостаточная доля аутсорсинга также определяет низкую инновационность экономики, так как инновации рождаются в малом предпринимательстве, а не в крупных государственных корпорациях. В завершение статьи автор определяет факторы, которые будут способствовать или, наоборот, мешать развитию аутсорсинга в экономике России и, следовательно, влиять на ее конкурентоспособность на мировом рынке
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
