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

Hacettepe University Faculty Of Medicine ENT Department, Speciality Thesis, Ankara 2019. Computed tomography (CT) has a very importent place for the evaluation of the anatomical structures, the localization of pathology and spread of the disease, the determination of extent of erosion in order to predict possible complications.
The aim of our study is to compare the findings of temporal bone CT with intraoperatively observed pathological findings and to assess the value of temporal bone CT in preoperative evaluation, diagnosis and prediction of complications of chronic otitis media surgery therefore to determine its value in preoperative surgical planning. A group of 261 patients who were operated between 2012 and 2016 and have preoperative temporal bone CT were included in the study. Parameters evaluated both on CT and during surgery were malleus, incus, stapes, facial canal, LSC and middle ear status. The images (CT) were evaluated by a single radiologist who is experienced on temporal bone radiology and blinded to the surgical results. The results were compared with the surgical findings and the correct classification number, concordance and correlation of CT were determined. Correlation of findings regarding malleus was found to be CCN: 79.3%, Kappa: 35.2% (moderate compliance), Cramer V: 35.2% (low level correlation) (p <0.001). For incus, the CCN: 77.8%, kappa: 57.3% (moderate compliance), Cramer V: 54.7% (moderate correlation) (p <0.001), for facial canal, CCN: 89.6%, Kappa: 46% (moderate compliance), Cramer V: 44.8% (moderate correlation) (p <0.001). For middle ear status, CCN: 46%, Kappa: 26.8% (low compliance), Cramer V: 39% (low & poor correlation) (p <0.001). For stapes,specificity was 89%, sensitivity was 86%, NPV: 97%, PPV: 62%, Kappa: 66.1% (good compliance), Phi: 67.4% (moderate correlation) (p <0.001). For incudostapedial joint, specificity was 90.3%, sensitivity: 75.5, NPV: 84.3%, PPV: 84.2%, Kappa: 66.1% (good compliance), Phi: 67.2% (moderately correlated) (p <0.001). For LSC specificity: 98.8%, sensitivity: 83.3, NPV: 99.6%, PPV: 62%, Kappa: 70.7% (good level of compliance), Phi: 71.4% (strong correlation). As a result, there was a low level of correlation and compliance between the radiological and surgical findings of malleus and middle ear while there was a moderate correlation and compliance for incus and facial canal. There was a good compliance regarding stapes and incodustapedial joint but a moderate correlation. There was only good compliance and strong correlation for LSC erosion.TEŞEKKÜR İV

Hacettepe Üniversitesi Tıp Fakültesi KBB Anabilim Dalı Uzmanlık Tezi, Ankara 2019. Kronik otitis medianın (KOM) değerlendirilmesinde bilgisayarlı tomografi (BT); anatomik yapıların durumu, hastalığın lokalizasyonunu ve yapmış olduğu tahribatın saptaması açısından önemli bir yere sahiptir. Çalışmamızın amacı, temporal kemik BT bulgularıyla, KOM cerrahisi esnasında saptanan bulguların kıyaslanması ve bu bilgi ışığında bilgisayarlı tomografinin, KOM tanısında ve cerrahi planlamasındaki olası değerinin araştırılmasıdır. Çalışmaya 2012-2016 yılları arasında KOM nedeni ile cerrahi uygulanmış ve cerrahi öncesinde temporal BT tetkiki mevcut olan toplam 261 hasta dahil edildi. Mevcut ameliyat notlarından; kemikçik zincirde hasar olup olmadığı, fasiyal kanal ve lateral semisirküler kanalda (LSSK) dehisans olup olmadığı ve orta kulağın mukozasına ait veriler elde edildi. Temporal BT görüntüleri cerrahi bulgulardan habersiz tek bir radyolog tarafından tekrar değerlendirildi. Radyolog tarafından tespit edilen temporal BT sonuçları cerrahi bulgular ile karşılaştırıldı. Temporal BT‘nin doğru sınıflama oranı (DSO), cerrahi ile uyumu (Kappa), korelasyonu (Cramer V, Phi) ve tanısal olumsallık değerleri (seçicilik, duyarlılık, pozitif kestirim değeri, negatif kestirim değeri) istatistiksel olarak hesaplandı. Preoperatif BT‘nin malleus için: DSO: %79.3, Kappa: %35.2 (orta düzey uyum), Cramer V: %35.2 (düşük düzeyde korelasyon) bulundu (p<0.001). İnkus için: DSO: %77.8, Kappa: %57.3 (orta düzeyde uyum), Cramer V: %54.7 (orta düzeyde korelasyon) bulundu (p<0.001). Stapes için seçicilik: %89, duyarlılık: %86, negatif kestirim değer (NKD): %97, pozitif kestirim değer (PKD): %62, Kappa: %66.1 (iyi düzeyde uyum), Phi: %67.4 (orta düzeyde korelasyon) bulundu (p<0.001). İnkudostapedial eklem için: seçicilik: %90.3, duyarlılık: 75.5, NKD: %84.3, PKD: %84.2, Kappa: %66.1 (iyi düzeyde uyum), Phi: %67.2 (orta düzeyde korelasyon) bulundu (p<0.001). Fasiyal kanal için: DSO: %89.6, Kappa: %46 (orta düzeyde uyum), Cramer V: %44.8 (orta düzeyde korelasyon) saptandı (p<0.001). Orta kulak için: DSO: %46, Kappa: %26,8 (düşük düzeyde uyum), Cramer V: %39 (zayıf korelasyon) saptandı (p<0.001). LSSK için: seçicilik: %98.8, duyarlılık: 83.3, NKD: %99.6, PKD: %62, Kappa: %70.7 (iyi düzeyde uyum), Phi: %71.4 (kuvvetli korelasyon) bulundu. Sonuç olarak malleus ve orta kulak boşluğunun durumu konusunda radyolojik değerlendirme ile cerrahi bulgular arasında düşük düzeyde uyum ve korelasyon varken, inkus ve fasiyal kanal için radyolojik değerlendirme ile cerrahi bulgular arasında orta düzeyde uyum ve korelasyon bulundu. Stapes ve inkudostapedial eklemde radyolojik değerlendirme ile cerrahi bulgular arasında iyi düzeyde uyum, fakat orta düzeyde korelasyon bulundu. Sadece LSSK erozyonu konusunda radyoloji ve cerrahi değerlendirme arasında iyi düzeyde uyum ve kuvvetli düzeyde korelasyon saptandı
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.
