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
Incremental Value of Mean Platelet Volume as a Marker of Decompensation in Patients with Congestive Heart Failure
No full textAmaç: Konjestif kalp yetmezliği morbidite, bozulmuş yaşam kalitesi ve azalmış sağkalım ile ilişkili önemli bir halk sağlığı sorunudur. Konjestif kalp yetmezliği hastaları dekompanse olduklarında, artmış intra ve ekstraselüler sıvı birikimi çeşitli semptomlara yol açar. Dekompansasyon sırasında hücre içi sıvı birikiminin, ortalama trombosit hacmi gibi hücresel boyutlarla ilgili parametrelerde bir artışa yol açabileceğini düşünerek, bu çalışmada konjestif kalp yetmezliği hastalarında dekompanse ve stabil durumlar arasında ortalama trombosit hacmi açısından bir fark olup olmadığını araştırmayı amaçladık. Gereç ve Yöntem: Dekompanse konjestif kalp yetmezliği nedeniyle hastaneye yatırılan hastalar çalışmaya alındı. Transtorasik ekokardiyografik inceleme ve hemogram da dahil olmak üzere rutin kan testleri hastaneye başvuru sırasında kaydedildi. Tüm hastalar hastanede yatış sırasında diüretik tedavisi aldı. Hastaların fonksiyonel kapasiteleri, günlük idrar miktarı ve kilo kaybı hastanede yattığı sürece kaydedildi. Hastalar stabil halde taburcu edilirken rutin tetkikleri tekrarlanarak kaydedildi. Bulgular: Dekompanse konjestif kalp yetmezliği tanısıyla hastaneye yatırılan 120 hasta çalışmaya dahil edildi. Konjestif kalp yetmezliği hastalarında ortalama sol ventrikül ejeksiyon fraksiyonu % 31,8±5,3 idi. Hastaların ortalama hastanede yatış süreleri 7 (5-8) gün olarak hesaplandı. Günlük ortalama furosemid dozu 70 (50-80) mg iken, hasta başına günlük ortalama idrar çıkışı 2166±341 mL ve hasta başına toplam ortalama kilo kaybı 10 (8-11) kg idi. Dekompansasyon sırasında ortalama trombosit hacmi, taburculuk öncesi stabil haline göre önemli ölçüde daha yüksekti (10,1±1,5 vs. 8,1±1,2; p= 0,001). Ayrıca kilo verme miktarı ile hastanede yatış sırasındaki ortalama trombosit hacmi değerlerindeki fark arasında pozitif korelasyon izlendi (r2:0.93; p <0,001). Sonuç: Dekompanse konjestif kalp yetmezliği hastalarında ortalama trombosit hacmi artmış ve hastanede yatış sırasında diüretik tedavisine yanıt olarak azalmıştır. Bu nedenle, konjestif kalp yetmezliği hastalarının takibi sırasında ortalama trombosit hacmi dekompansasyonun bir belirteci olarak kullanılabilir ve klinisyene, diüretik tedavisinin başarısı hakkında bir fikir verebilir.Objective: Heart failure is a major public health problem that is related to substantial morbidity, impaired quality of life and diminished survival. When heart failure patients decompensate, increased intra and extracellular fluid accumulation leads to various symptoms. We hypothesized that intracellular fluid accumulation during decompensation may lead to an increase in parameters related to cellular dimensions such as mean platelet volume. The aim of the study is to investigate whether there is a difference in terms of mean platelet volume in heart failure patients between decompensated and stable states. Material and Method: Patients who were hospitalized due to decompensated heart failure were enrolled to the study. Transthorasic echocardiographic examination and routine blood tests including complete blood count were performed upon admission to hospital. All patients received diuretic treatment during hospitalization. Functional capacities, urine output and weight loss of the patients were recorded during hospitalization. Control blood tests were performed before discharge from the hospital in a stable state. Results: This study enrolled 120 patients with decompensated heart failure. The median left ventricular ejection fraction was 31.8±5.3 % in patients. The mean hospitalization time was 7 (5-8) days and mean daily diuretic dose per patient was 70 (50-80) mg. The mean daily urine output per patient was 2166 ± 341 mL and mean weight loss per patient was 10 (8-11) kg. Mean mean platelet volume during decompensation was significantly higher than that of stable state before discharge (10.1±1.5 vs. 8.1±1.2; p= 0.001). Also there was a strong positive correlation between the quantity of weight loss and the difference between mean platelet volume values during hospitalization (r2:0.93; p <0.001). Conclusion: Mean platelet volume is increased in decompensated heart failure patients and decreases in response to diuretic treatment during hospitalization. Thus, mean platelet volume may be used as a marker of decompensation during the follow up of heart failure patients and gives the clinician an opinion about the success of the diuretic treatment
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.
