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
Nasıcon türü malzemelerin üretilmesi ve pillerde uygulanması

Rüzgar ve güneş enerjisi gibi yenilenebilir enerji kaynaklarını daha verimli kullanabilmek için de yeni enerji depolama alanlarına ihtiyaç duyulmuştur. Aynı zamanda artan mobil erişilebilirlik ihtiyacı da performanslı çalışan, enerji depolama alanlarına olan gereksinimi arttırmıştır. Son yıllarda elektrikli araçların yaygınlaşması da enerji depolama alanındaki rekabeti arttırmıştır. Lityum-iyon pil (LIB) teknolojisi şu anda hibrid ve tam elektrikli araçlar için tercih edilen enerji depolama teknolojisidir. Ancak lityum rezervinin giderek azalıyor oluşu, geri dönüşümünde yaşanan problemler, coğrafi ve politik kısıtlamalardan kaynaklanan maliyet artışı, üretimin yüksek maliyetlerde gerçekleşmesine neden olmuştur. Sodyum metali yerkabuğunda ağırlıkça %2,6 oranında bulunmaktadır. Bu oranıyla en çok bulunan altıncı element ve en çok bulunan birinci alkali metaldir. Bu yüzden, lityuma en iyi alternatif, kimyasal olarak da birbirine yakın ve benzer özelliklere sahip olan sodyumdur. Bu nedenle sodyum iyon piller, son on yılda yoğun bir şekilde yeniden incelenmiş ve teknolojik açıdan uygulanabilir olduğu görülmüştür. Bu çalışmada, sol jel yöntemi kullanılarak hazırlanan, sodyum süper iyonik iletken (NASICON) yapılı Na3V2(PO4)3 (NVP), P2- tipi Na0,67[Mn0,65Fe0,2Ni0,15]O2 (NaMNF) ve P2- tipi Na0,67[Mn0,65Co0,2Ni0,15]O2 (NaMNC) katot malzemelerinin fiziksel ve kimyasal özellikleri çeşitli analiz yöntemleriyle incelenmiştir. Ayrıca üretilen malzemeler, pozitif elektrot olarak, CR2016 buton tipi pil içerisine yerleştirilerek, elektrokimyasal testleri yapılmıştır. Elektrokimyasal test sonuçları, sol jel yöntemiyle üretilen katotların, gayet iyi bir ektrokimyasal performans sergilediğini göstererek, sodyum iyon piller için gerçekten umut vaat ettiğini doğrulamaktadır.The negative effects of fossil fuels to environmental and human health, which are used to supplying increased energy needs, have put the scientists in search of alternative energy sources. New energy storage areas have been needed to use renewable energy resources such as wind and solar energy more efficiently. At the same time, the need for increased mobile accessibility has also increased the need for energy-efficient storage sites. The widespread use of electric vehicles in recent years has also increased competition in energy storage. Lithium-ion battery (LIB) technology is currently preferred energy storage technology for hybrid and fully electric vehicles. However, Lithium cost is steadily increasing, due to geographical and political constraints, the problems in recycling and day by day decreasing of Li reserve. Sodium metal comprises about 2.6% by weight of the earth's crust. Considering this rate, sodium is the sixth most abundant element and the first alkali metal. Thus, sodium is the best alternative to lithium due to its so similar chemical properties. For this reason, sodium ion battery field has been intensively re-studied over the past decade and show us that technologically it is practicable. In this study, the physical and chemical properties of NASICON structured NVP, P2-type NaMNF and NaMNC cathode materials prepared by sol-gel method were investigated by various analytical methods. In addition, the produced materials were electrochemically tested by placing in the CR2016 button-type battery as the positive electrode. The electrochemical test results demonstrate that the cathodes produced by the sol-gel method exhibit a good ectrochemical performance and confirm that produced cathodes really show promise for sodium ion batteries
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.
