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
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
Studies on the toxic, repellent and attractive effects of some plant essentıal oils against adults of Dorcadion pseudopreissi Breuning (Coleoptera: Cerambycidae)
No full textDorcadion pseudopreissi Breuning, özellikle çim alanlarında ekonomik düzeyde zarara neden olmaktadır. Bu çalışmada, 4 farklı bitkisel uçucu yağın (okaliptus,sarımsak,nane,biberiye) zararlı böceğin ergin bireylerine karşı toksik etkisi incelenmiştir. Denemede her bir yağın 0,01, 0,1 ve 1ml dozları kullanılmış, yağların uygulanmasından sonra 24., 48., ve 72. saatte ölümleri kaydedilmiş ve çalışma beş tekerrürlü olarak yürütülmüştür. Deneme sonucuna göre bitkisel yağlardan en fazla etkili olan sırasıyla okaliptus yağı, sarımsak yağı, nane ve biberiye yağı olmuştur. Kullanılan yağlar içerisinde D. pseudopreissi için biberiye yağı orta ve yüksek dozlarda yağa maruz kalma süresi arttıkça ölüm oranlarının arttığı gözlemlenmiştir. Nane yağının ise 0,01 ml dozunda 24. saat ve 48. saatinde ölüm oranında bir artış olmamış, 72. saatte ise %1,7’lik bir artış olmuştur. Diğer dozları ise artarak devam etmiştir ve en fazla ergin ölüm oranı 0,1 ml dozunda olmuştur. Okaliptus yağında ise tüm dozlarında 24., 48., saatte herhangi bir artış olmamıştır. 72. saatte, 1 ml dozda %60’lık artış yaptığı gözlemlenmiştir. Sarımsak yağında tüm dozlarda yağa maruz kalma süresi arttıkça ergin ölümü artmıştır. En fazla ölüm 0,1 ml dozunda gerçeklemiştir. 72. saat sonunda sarımsak yağında 0,1 ml dozu 0,01 ml doza göre etkisi az görülmüştür. Bununla birlikte, yağlara 72 saat süre maruz kaldıktan sonra D. pseudopreissi’nin okaliptüs ve sarımsak yağında %41,7, nane yağında %40 ölüm oranıyla hafif derecede etkili olmuş, biberiye yağında ise etkisiz olduğu saptanmıştır. Y-tüp olfaktometre kullanılarak yapılan araştırmada, 4 farklı uçucu yağın (çimen,limon, karanfil,lavanta) D. pseudopreissi erginlerinin kokuya olan yönelim davranışları üzerine etkisi çalışılmıştır. Denemede her bir yağın 0,01, 0,1 ve 1ml dozları kullanılmıştır. Çalışma üç tekerrürlü olarak yürütülmüştür. Olfaktometre çalışma sonuçlarına göre bitkisel uçucu yağlardan etkili olanlar sırasıyla çimen yağı, limon yağı, karanfil yağı ve lavanta yağı şeklindedir. Kullanılan yağlar içerisinde D. pseudopreissi için karanfil yağında dozlar arttıkça kokuya yönelimlerin arttığı gözlemlenmiştir. Limon yağında ise doz arttıkça kokuya yönelim azalmıştır. Çimen yağında ve lavanta yağında doz arttıkça kokuya yönelim değişmemiştir. Uygulama sonunda ise erginler en fazla çimen yağına % 66,7, limon yağına % 64 oranında yönelmiştir. Karanfil yağı ve lavanta yağlarına % 41,7 yönelmişlerdir. Buna göre, bu yağların D. pseudopreissi’ye karşı entegre mücadele programlarında tavsiye edilebileceği ve tuzaklarda kullanılabileceği düşünülmektedir.Dorcadion pseudopreissi Breuning, particularly causes economic damage in grasslands. In this study, the toxic effects of four different plant essential oils (eucalyptus, garlic, mint, rosemary) on adult stages of the insect pest were investigated. In the experiment, 0.01, 0.1 and 1 ml doses of each oil were used, and deaths were recorded at 24, 48 and 72 hours after the application of the oils, and the study was conducted with five replications. According to the results, the most effective oils were eucalyptus oil, followed by garlic oil, mint, and rosemary oil. Among the oils used, rosemary oil caused increased mortality in D. pseudopreissi at medium and high doses as the exposure time to the oil increased. For mint oil, no increase in mortality was observed at the 24th and 48th hours for the 0.01 ml dose, but a 1.7% increase was recorded at the 72nd hour. Mortality continued to rise with the other doses, and the highest mortality rate occurred at the 0.1 ml dose. For eucalyptus oil, no increase was observed at 24 and 48 hours for all doses, but a 60% increase in mortality was noted at the 72nd hour at the 1 ml dose. In garlic oil, as the exposure time increased for all doses, the adult mortality also increased. The highest mortality occurred at the 0.1 ml dose. At the 72nd hour, the effect of the 0.1 ml garlic oil dose was lower compared to the 0.01 ml dose. However, after 72 hours of exposure, However, after 72 h of exposure to oils, D. pseudopreissi was found to be mildly effective with 41.7% mortality in eucalyptus and garlic oils, 40% in peppermint oil, and ineffective in rosemary oil. In a Y-tube olfactometer study, the effects of four different essential oils (grass, lemon, clove, lavender) on the odor orientation behavior of D. pseudopreissi adults were investigated. In the experiment, 0.01, 0.1, and 1 ml doses of each oil were used. The study was carried out in three replications. According to the results of the olfactometer study, the most effective herbal essential oils were grass oil, lemon oil, clove oil, and lavender oil, respectively. Among the oils used, it was observed that the orientation towards the odor increased as the dose increased in clove oil. In lemon oil, the orientation decreased as the dose increased. In grass and lavender oils, the orientation did not change as the dose increased. At the end of the experiment, the adults were most attracted to grass oil (66.7%) and lemon oil (64%), while 41.7% of them were attracted to clove and lavender oils. Accordingly, it is thought that these oils can be recommended in integrated control programs against D. pseudopreissi and can be used in traps

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.
