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
Determination of suitable land for special cimate requirements of agricultural products in Mediterranean Region (Turkey) by weighted overlay analysis: Akdeniz Bölgesi'nde (Türkiye) yetiştirilen tarım ürünlerinin özel iklim isteklerine uygun arazilerin ağırlıklı çakıştırma analizi ile belirlenmesi
Get PDFIn this study, the areas where wheat, corn, cotton, grape and olive plants of high economic value in the Mediterranean Region can be grown in accordance with the special climate requirements have been determined with Weighted Overlay Analysis in Geographical Information Systems. Burdur, Isparta, Kahramanmaras, Antalya, Mersin, Adana, Osmaniye and Iskenderun were selected for this purpose as the automatic meteorological observation stations having long observation period and homogeneous distribution. Including the years between 1991-2017, the daily average temperature, daily average maximum temperature, daily average minimum temperature and daily total rainfall data were used as climate data along the elevation and slope data generated from the digital elevation model (DEM) as topography data. Phenological periods of agricultural products from Turkey Phenology Atlas and special climate requirements in these periods according to literature review were determined as first step of the methodology. Then, climate data were arranged according to phenological periods and transferred to ArcGIS 10.1 program. Climate data were interpolated by IDW method in order to create a continuous surface from climate data. The weighted overlay tool included in the ArcGIS 10.1 program was applied to the topography data and interpolated climate data. The areas compatible with temperature and precipitation conditions which are special climate requirements of the agricultural products and the areas where the elevation is below 1000 meters and the slope is below %20 are classified as suitable; and the areas that do not meet these criteria are classified as unsuitable. Then the distribution maps are constructed. It is determined that the areas classified as suitable for agricultural production by the study overlap with the areas currently having the greatest amount of agriculture production. According to the results obtained from the analysis; the effect of elevation, hill and climate factors in determining the areas where agricultural products can be cultivated economically is clearly determined.

Özet
Bu çalışmada Akdeniz Bölgesi'nde ekonomik değeri yüksek olan buğday, mısır, pamuk, üzüm ve zeytinin özel iklim isteklerine uygun olarak yetiştirilebileceği alanlar Coğrafi Bilgi Sistemleri’nde Ağırlıklı Çakıştırma Analizi (Weighted Overlay Analysis) ile tespit edilmiştir. Bu amaçla çalışma alanındaki gözlem süresi uzun olan ve homojen dağılım gösteren otomatik meteoroloji gözlem istasyonlarından Burdur, Isparta, Kahramanmaraş, Antalya, Mersin, Adana, Osmaniye ve İskenderun seçilmiştir. Bu istasyonlara ait 1991-2017 yılları arasını kapsayan, günlük ortalama sıcaklık, günlük ortalama maksimum sıcaklık, günlük ortalama minimum sıcaklık, günlük en yüksek maksimum ve en düşük minimum sıcaklık ve günlük toplam yağış verileri ile sayısal yükseklik modelinden (dem) oluşturulan yükselti ve eğim verileri, topoğrafya verisi olarak kullanılmıştır. Metot olarak, öncelikle tarım ürünlerinin Türkiye Fenoloji Atlası’ndan fenolojik dönemleri ve literatürden bu dönemlerdeki özel iklim istekleri belirlenmiştir. Fenolojik dönemlere göre düzenlenen iklim verileri ArcGIS 10.1 programına aktarılmıştır. İklim verilerinden sürekli yüzey oluşturabilmesi için sıcaklık ve yağış değerleri IDW yöntemiyle interpole edilmiştir. Topoğrafya verileri ve interpole edilmiş iklim verilerine ArcGIS 10.1 programında weighted overlay aracıyla ağırlıklı çakıştırma analizi uygulanmıştır. Tarım ürünlerinin özel iklim isteklerinden sıcaklık ve yağış koşullarına uyumlu, yükseltinin 1000 metre ve eğimin %20’nin altında olduğu alanlar uygun, bu kriterleri sağlamayan alanlar uygun değil olarak sınıflandırılmış ve dağılış haritaları yapılmıştır. Tarımsal üretim için uygun olan alanların tarımsal üretim tutarlarının da yüksek olduğu alanlara karşılık geldiği gözlemlenmiştir. Analizden elde edilen sonuçlara göre; bölgedeki yükselti ve eğim faktörleri ile iklim koşullarının tarım ürünlerinin ekonomik olarak yetiştirilebileceği alanları belirlemedeki etkisi açık bir şekilde tespit edilmiştir
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

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.
