Coronavirus (Covid-19) pandemisinin işletmelerin finansal performansına etkisi: Borsa İstanbul (BİST) uygulaması / Effect of coronavirus (Covid-19) pandemic on financial performance of businesses: Borsa İstanbul (BIST) implementation
No full textCovid-19 pandemisi önceki pandemilerden farklı olarak, çok kısa sürede pandemik hastalığa dönüşerek toplum sağlığının yanında küresel ekonomiyi ve finansal piyasaları derinden etkileyen çok boyutlu bir küresel krize dönüşmüştür. Küresel ekonominin bir parçası olarak Tükiye ekonomisi ve finansal piyasaları da Covid-19 pandemisinden derinden etkilenmiştir. Bu çalışmanın amacı; Borsa İstanbul (BİST)'te işlem gören imalat sanayi işletmelerinin finansal performansları üzerinde Covid-19'un ne denli etkili olduğunu ve işletmelerin finansal performansları üzerinde hangi sonuçlara yol açtığını ortaya koymaktır. Çalışmada kullanılmak amacıyla BİST'te işlem gören ve verilerine düzenli olarak ulaşılabilen 104 imalat sanayi işletmesi seçilmiş ve bu işletmelerin 2019-2020 yıllarını içeren 8 çeyreklik finansal verilerinden yararlanılmıştır. Bağımlı değişken olarak; aktif karlılık oranı, özsermaye karlılık oranı, net kar marjı ve faaliyet kâr marjı kullanılmıştır. Ayrıca, bağımsız değişken olarak; işletme büyüklüğü, likidite oranı ve maddi duran varlıklardan yararlanılmıştır. Bağımlı ve bağımsız değişkenlerin işletmelerin toplam satışları içerisinde yurtdışı satışlarının oranına bağlı olarak değişip değişmediği incelenmiştir. Bu doğrultuda çalışmada Panel Veri Analiz yöntemi kullanılmıştır. Çalışmanın sonucunda; Covid-19 pandemisinin işletmelerin aktif karlılığına olumsuz etkisinin satış oranları yüksek olan işletmelerde daha fazla hissedildiği, toplam satışlar içerisinde ihracatın payı düşük olan işletmelerde özsermaye karlılığındaki olumsuz etkinin yüksek ihracat payı olan işletmelerden daha fazla olduğu sonucuna ulaşılmıştır. İşletme net kâr marjındaki olumsuz etkinin düşük ihracat payı olan işletmelerden daha fazla olduğu görülmüştür. Aynı zamanda, toplam satışları içerisinde yurtdışı (ihracat) satışları yurtiçi satışlarından yüksek olan işletmelerin işletme faaliyet kâr marjındaki olumsuz etkinintoplam satışlarına oranla ihracat payı düşük olan işletmelerden daha fazla olduğu sonucuna ulaşılmıştır. Anahtar Kelimeler: Finansal performans, Covid-19, kriz, imalat sanayi, Borsa İstanbul (BİST).Unlike previous pandemics, the Covid-19 pandemic turned into a pandemic in a very short time, turning into a multidimensional global crisis that deeply affected the global economy and financial markets as well as public health. As a part of the global economy, the Turkish economy and financial markets have also been deeply affected by the Covid-19 pandemic. The aim of this study is to reveal how Covid-19 is effective on the financial performances of manufacturing industry enterprises traded in Borsa Istanbul (BIST) and what consequences it has on the financial performances of businesses. In order to be used in the study, 104 manufacturing industry enterprises that are traded on the BIST and whose data can be accessed regularly were selected and the financial data of these enterprises for the period 2019-2020 were used. As the dependent variable; return on assets ratio, return on equity ratio, net profit margin and operating profit margin are used. Also, as an independent variable; business size, liquidity ratio and tangible assets were used. It has been examined whether the dependent and independent variables change depending on the ratio of foreign sales within the total sales of the enterprises. In this direction, Panel Data Analysis method was used in the study. According to this study, it has been concluded that the negative effect of the Covid19 pandemic on the profitability of the enterprises is felt more in the enterprises with high sales rates, and the negative effect on the return on equity is more in the enterprises with a low share of exports in total sales than in enterprises with a high export share. It has been observed that the negative effect on the net profit margin of the enterprise is more than the enterprises with low export share. At the same time, it has been concluded that the negative effect on the operating profit margin of the enterprises whose foreign (export) sales are higher than their domestic sales in their total sales is more than the enterprises with a low export share compared to their total sales.

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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
