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
Proteinürisi olan 3 farklı hasta grubunda hastaların anjiotensin dönüştürücü enzim inhibitörü ve/veya anjiotensin reseptör blokörü tedavilerinin karşılaştırılması ve iki yıllık takiplerinin değerlendirilmesi
Full text linkKronik böbrek hastalığı giderek yaygınlaşan evrensel bir sağlık problemi olup Türk Nefroloji Derneği tarafından gerçekleştirilen CREDİT (Chronic REnal Disease In Turkey) çalışmasına göre ülkemizdeki prevalansı %15,7 olarak rapor edilmiştir. Kronik böbrek hastalığının ilerleyici özelliğine en fazla katkıda bulunan iki etken proteinüri ve hipertansiyondur. Proteinüri varlığı ve derecesi kronik böbrek hastalığı için tanısal, prognostik ve tedavi göstergesi olan bir parametredir. Kan basıncı kontrolü ile beraber protein atılımının azaltılmasıyla böbrek hastalığının progresyonunda yavaşlama olduğu yapılan çalışmalarda kanıtlanmıştır.
Çalışmamıza, 2009-2015 yılları arasında Ankara Başkent Üniversitesi Hastanesi’nde takip edilen 1gr/gün ve üzerinde proteinürisi olan diyabetik nefropati, glomerülonefrit, renal transplantasyon alıcısı olan toplam 162 hasta dahil edildi. Hastaların 2 yıllık verileri elde edildi. Renal transplantasyon alıcısı hastalarda proteinürik etkisinden dolayı sirolimus kullanan hastalar çalışmaya alınmadı. Hastaların proteinüri miktarı 24 saatlik idrarda türbidimetrik yöntem ile çalışıldı. Anjiotensin Converting Enzim (ACE) inhibitörü kullanan hastalar (grup 1), Anjiotensin Reseptör Blokörü (ARB) kullanan hastalar (grup 2) ve ACE inhibitörü ve ARB tedavilerini birlikte kullanan hastalar (grup 3) olmak üzere hastalar 3 gruba ayrıldı. Her bir hastanın demografik, klinik ve laboratuvar değerleri retrospektif olarak kaydedildi. Hastaların yaş, cinsiyet, 0-1-3-6-9-12-18-24. aydaki kan üre nitrojen (BUN), kreatinin, sodyum, potasyum, hemoglobin değerleri, 24 saatlik idrarda proteinüri miktarı, kreatinin klirensi, kullandığı ilaçlar, böbrek biyopsi sonucu, 0 ve 24. aydaki ekokardiyografi bulguları, immunsupresif ajan kullanımı, ek hastalıkları, proteinüri etyolojileri kaydedildi.
Çalışmamızda bütün gruplarda başlangıç proteinüri değeri ortamaları ile diğer tüm aylardaki kontrol proteinüri değerileri ortalamaları arasında istatistiksel olarak anlamlı bir düşüş gözlenmiştir. Her 3 hasta grubunda da proteinüri kontrolü sağlanmıştır.
ACE inhibitörü kullananlarda 0. aydaki kreatinin değeri ile 24. aydaki kreatinin değeri ortalamaları arasında istatistiksel olarak anlamlı bir artış gözlenmiştir. ACE inhibitörü ve ARB kullanan grupta ise 0. aydaki kreatinin değeri ile 9.,12. ve 18. aydaki kreatinin değeri ortalamaları arasında istatistiksel olarak anlamlı bir artış gözlenmiştir.
Hastaların kreatinin klirensi değerlerindeki değişim incelendiğinde ise ACE inhibitörü kullanan grup 1’deki hastaların 9. aydan itibaren kreatinin klirensi değerlerinin anlamlı olarak düştüğü, kombine ilaç tedavisi alan grup 3’teki hastaların ise 12. aydan itibaren kreatinin klirensinde istatistiksel olarak anlamlı bir düşüş izlendiği, sadece ARB kullanan grup 2 hastalarında ise kreatinin klirensinde istatistiksel olarak anlamlı bir değişim saptanmadığı görüldü.
Çalışmamızda, sol ventrikül konsantrik hipertrofisi ve ejeksiyon fraksiyonu açısından ilaç kullanımına göre gruplar karşılaştırıldığında gruplar arasında istatiksel olarak anlamlı fark saptanmadı.
Sonuç olarak primer hastalığına bakmaksızın >1000 mg/gün'ün üzerinde proteinürisi olan hastalarda ACE inhibitörü veya ARB tedavisi başlanmalıdır. Proteinürisi kontrol altına alınamayan hastalarda, ACE inhibitörü ve ARB'nin birlikte kullanımı ancak seçilmiş, yakın takip edilebilecek ve uyumlu hastalar için söz konusu olabilir.
Diyabetik nefropatide olduğu gibi, glomerülonefrit nedeniyle takipte olan ya da böbrek nakilli hastaların tedavisi ve tedaviye cevapları birbirine benzerlik göstermektedir. Her 3 hasta grubunda da proteinüri kontrolü öncelikli hedef olarak görünmektedir.
Chronic kidney disease (CKD) is a growing problem all over the world. Turkish Nephrology Society demonstrated that prevalance of CKD in Turkey is 15.7% (CREDİT). Proteinuria and hypertension are two factors which are very important for the progression of chronic kidney disease. The degree of proteinuria is both a prognostic and a diagnostic parameter, furthermore it’s important to evaluate the treatment response. It’s shown that, good control of hypertension and reducing proteinuria slows down the progression of the CKD.
In this study, we included 168 patients with diabetic nephropathy, glomerulonephritis, renal transplantation who were followed through the years 2009-2015 in Ankara Başkent University Hospital Nephrology Department and who had more than 1 gr of daily urinary protein excretion. Patients using sirolimus were excluded from the study. 24-h urinary protein excretion was determined by turbidimetric method. Patients were divided into three groups according to the medications used for proteinuria as; users of angiotensin converting enzyme inhibitors (group 1), users of angiotensin receptor blockers (group 2), users of both angiotensin converting enzyme inhibitors and angiotensin receptor blockers (group 3). Demographic features (age, gender), clinical parameters (the disease which is responsible for proteinuria, co-morbid diseases, medications, echocardiographic changes) laboratory parameters (blood urea nitrogen, creatinine, sodium, potassium, hemoglobin, 24-h urinary protein excretion, creatinine clearence) were recorded. Echocardiographic changes were recorded for both months 0 and 24. Laboratory tests were recorded for months 0-1-3-6-9-12-18-24. According to our study results; the initial 24 hours proteinuria levels showed statistically significant decrease in the follow up. Proteinuria has been taken under control in all 3 groups.
The mean serum creatinine levels at the initiation of the study were significantly higher in patients who were receiving ACE-Is compared to the mean creatinine levels in the 24th month. The patients who were using both ACE-Is and ARBs had significantly higher creatinine levels after the 9th month of the study.
When we compared the patient groups according to the changes in the creatinine clearance; group 1 patients (ACEI group) showed a significant decrease after the 9th month of the study while patients in group 3 (ACEI + ARB) showed a significant decrease after the 12nd month of the study and group 2 patients (ARB) showed no significant decrease in creatinine clearance.
In our study, no statistically significant change was obtained for left ventricular concentric hypertrophy and ejection fraction in the patient groups between the initiation and the end of the study.
In conclusion, the patients who have proteinuria higher than 1000 mg per day should receive ACEI or ARB therapies. Combined therapy of ACEIs and ARBs should only be used in selected patients who could be monitorized closely.
The anti-proteinuric therapy is similar in diabetic nephropathy, glomerulonephritis as well as in kidney transplant recipients. Proteinuria seems to be the main target in all patient groups
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.
