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
Şok hastasında sıvı yanıtının değerlendirilmesinde invaziv nabız basıncı varyasyonu (pulse pressure variation-ppv) indeksine karşılık noninvaziv atım hacmi varyasyonu (stroke volum variation-svv) indeksinin karşılaştırılması
No full textHemodinamisi unstabil şoklu kritik hastalarda sıvı tedavisinin düzenlenmesi hayati önem taşımakta olup pozitif sıvı dengesi artmış mortaliteyle ilişkili olduğundan sıvı tedavisine yanıt verecek hastaların tespit edilmesi hipervolemiye sekonder komplikasyonları azaltacaktır. PLR testi eşliğindeinvaziv yöntem ile elde edilen dinamik parametrelerden olan PPV indeksini (nabız basıncı değişkenliği) noninvaziv yöntem olan USCOM cihazı ile saptanan SVV ve CQ değişkenliği değerlerinin sıvı yanıtını öngörmedeki başarısını karşılaştırmayı amaçladık. Trakya Üniversitesi Tıp Fakültesi Hastanesi Yirmi Yataklı Dahili Yoğun Bakım Ünitesinde 1 Haziran 2019-1 Şubat 2020 tarihleri arasında takibi yapılan, hemodinamisi stabil olmayan ve klinik olarak sıvı resüsitasyonu gerekliliği düşünülen, mekanik ventilatöre bağlı, vazopressör desteği alan şok tablosundaki hastalar ile hemodinamisi stabil kontrol grubu hastaları çalışmaya dahil edilmiştir. 18 yaşından küçük, gebeliği olan, pasif bacak kaldırma testi yapılması mümkün olmayan, anatomik olarak USCOM 1A cihazı probunun yerleşmesine engeli olan ve yasal varislerinden onam alınamayan hastalar çalışmaya dahil edilmemiştir. Çalışmamıza dahil edilen toplam 92 hastanın 46 ’sı hemodinamisi unstabil şok tablosundaki hastalar olup 46 hasta klinik olarak hemodinamik açıdan stabil kontrol grubu hastalarıdır. Çalışma grubuna dahil edilen hastaların %60,8 ’ inin septik şok, %32,6’ sının hipovolemik şok ve %6,6’ sının kardiyojenik şok tablosunda olduğu saptanmıştır. Hastaların cinsiyet dağılımına bakıldığında 45 (% 48,9) hasta erkek, 47 (%51)’si ise kadındı. Şoklu hastaların yaş ortalaması 63,13 ± 2,79 kontrol grubunun yaş ortalaması ise 70,78 ± 1,77 şeklinde saptanmıştır. çalışma grubun şok indeksi ortalaması 1,17 ± 0,03 iken kontrol grubunun ise 0,67 ± 0,02 şeklinde saptanmıştır. PLR Testi sonrası PPV, SVV ve CQ değerlerinde meydana gelen yüzdelik değişim oranları AUC değerlerinin her biri 0,5 ‘in altında kaldı, istatistiksel olarak anlamlı değişim göstermedi. Sıvı yanıtlılığını öngörmede PPV indeksi hem kendi başına hemde PLR testi sonrası istatistiksel olarak anlamlı bulundu.SVV indeksi tek başına ve PLR testi sonrasında da sıvı yanıtlılığı açısından istatistiksel olarak anlamlı değildi. Bununla birlikte mini sıvı provakasyonu (500cc ringer laktat) sonrası USCOM-1A cihazı ile elde edilen CQ değerlerinde meydana gelen değişim, sıvı yanıtını öngördürecek düzeyde anlamlı sonuç verdi (p<0,003). Şoklu spontan solunumu ve/veya aritmisi olanmekanik ventilatör bağımlı kritik hastada sıvı tedavi yönetiminde kardiyak output ölçümünde kullanılan invaziv yöntemler yüksek maliyet ve komplikasyon riski taşıdığından bolus verilen 500 ml ringer laktat yüklemesinin ardından USCOM cihazı ile ölçülen CO değişim oranının sıvı yanıtının test edilmesi amacıyla kullanılabileceğini düşünmekteyiz.Regulating fluid therapy in critical patients with haemodynamically unstable is vital, and since positive fluid balance is associated with increased mortality in patients with shock that’s why identifying patients who will respond to fluid therapy will reduce complications secondary to hypervolemia. We aimed to compare the success of predicting the liquid response of the SVV and CQ variability values determined by the non-invasive method, the PPV index (pulse pressure variability), which is one of the dynamic parameters obtained by the invasive method, with the PLR (passive leg raising) test. Patients in the shock table who were followed-up at Trakya University Faculty of Medicine Hospital twenty-bed Internal Intensive Care Unit between 1 June 2019 and 1 February 2020, who had hemodynamically unstable and clinically required fluid resuscitation, and who received vasopressor support, and patients with hemodynamically stable as a control group included in this study.Patients under 18 years of age, pregnant, unable to passive leg raising test, anatomically prevented the insertion of the USCOM 1A device probe and consent from their legal heirs could not be included in the study. Of the 92 patients included in our study, 46 patients were unstable shock table with hemodynamically, and 46 patients were selected as a control group who were hemodynamically stable. It was determined that 60.8% of the patients included in the study group were in the table of septic shock, 32.6% of them were hypovolemic shock and 6.6% of them were cardiogenic shock. Considering the gender distribution of the patients, 45 (48.9%) patients were male and 47 (51%) were female.The average age of shock patients was 63.13 ± 2.79, and the average age of the control group was 70.78 ± 1.77. While the average shock index of the study group was 1.17 ± 0.03, the control group was 0.67 ± 0.02.PPV index was statistically significant both on its own and after PLR test in predicting fluid responsiveness.The SVV index was not statistically significant in terms of fluid responsiveness alone and after the PLR test.However, the change in CQ values obtained with the USCOM-1A device after mini fluid provocation (500cc ringer lactate) gave a significant level to predict the fluid response (p <0.003). Since the invasive methods used in the measurement of cardiac output in fluid therapy management in the critical patients with shockwho either shockspontaneous breathing and /or has arrhythmia high costand complication risk, we think that the CO change rate measured by USCOM device after the 500 ml ringer lactate given bolus can be used to test the liquid response
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
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.
