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
Yoğun bakımda APACHE II, APACHE IV ve SAPS III skorlama sistemlerinin prognoz öngörüsü bakımından karşılaştırılması
No full textDetermination of mortality and morbidity is come into question because of admission of patients, who have simultaneously many problems and whose costs of treatment are high, to the intensive care units. For this reason, third generation versions of scoring systems were developed. In our study, we aimed to analyse effectiveness of APACHE II and SAPS III scoring systems retrospectively.This retrospective study was performed in Anesthesia Intensive Care Unit of Research and Training Center of Pamukkale University between July 2011 October 2011. 487 patients were included trial who were older than 18 years old and were treated at least 24 hours in intensive care. Patients were viewed excluding who were underwent coronary artery bypass surgery, who have major burn, who have been transplanted any organ, who have been transfered from another intensive care and by excluding the data of patients who admitted to intensive care many a time, at second and another admissions. Gender, age, weight, admission diagnosis, place from where admitted, intubation state, simultaneously illness, SAPS III, APACHE II and APACHE IV scores, time of stay in intensive care and in hospital before intensive care and mechanical ventilation of patients were recorded and their effects to mortality were analysed.Mortality was 26.1%. Patients were admitted to intensive care most from operating room (54.6%). The most frequent admission diagnosis was respiratory failure (30.7%). Mortality has been seen mostly at patients come from other services (48%). Mean values of scoring systems at patients died were significantly greater than patients lived but there has been no significant difference between scoring systems when they have been standardized. Through the simultaneous illness, mortality was significantly greater at gynecological, hematological, respiratory malignities and gastrointestinal diseaes (p0.05). In logistic regression analysis; risk of mortality has increased at the patients who have been admitted from emergency services and who have long stay times in intensive care and mechanical ventilation. The most correct mortality estimation has been observed, respectively, SAPS III>APACHE II>APACHE IV.In conclusion; despite the limited number of patients, we concluded that SAPS III and APACHE II systems had estimated mortality beter than APACHE IV.Key words: intensive care, scoring systems, mortality, SAPS III, APACHE IVYoğun bakım ünitelerine, eş zamanlı olarak birçok sorunu bulunan ve tedavi maliyetleri yüksek olan hastaların kabul edilmesinden dolayı mortalite ve morbiditenin önceden belirlenebilmesi önem kazanmaktadır. Bu nedenle, skorlama sistemlerinin üçüncü kuşak versiyonları geliştirilmiştir. Çalışmamızda, APACHE IV ve SAPS III skorlama sistemlerinin etkinliğini retrospektif olarak analiz etmeyi amaçladık.Bu retrospektif çalışma, Pamukkale Üniversitesi Eğitim Araştırma ve Uygulama Hastanesi Anestezi Yoğun Bakım ünitesinde Temmuz 2011 Ekim 2011 tarihleri arasında gerçekleştirilmiştir. 18 yaşından büyük, en az 24 saat yoğun bakımda tedavi gören 487 hasta çalışmaya dahil edilmiştir. Koroner arter baypas cerrahisi geçiren, majör yanığı olan, organ nakli yapılan, birçok kez yoğun bakıma kabul edilen hastanın ikinci ve diğer kabulündeki veriler, diğer bir yoğun bakımdan devir alınan hastalar çalışma dışı tutularak retrospektif olarak incelenmiştir. Hastaların cinsiyet, yaş, ağırlık, giriş tanısı, yoğun bakım ünitesine geldiği yer, entübe olup olmadığı, yandaş hastalıkları, APACHE II, IV ve SAPS III skorları, yoğun bakım ünitesine gelmeden önce hastanede yatış, yoğun bakımda kalış ve mekanik ventilasyon süreleri kaydedilip mortaliteye etkileri analiz edilmiştir.Mortalite, %26,1 idi. Yoğun bakıma hastalar en çok ameliyathaneden (%54,6) kabul edildi. En sık giriş tanısı, solunum yetmezliği (%30,7) idi. Mortalite, en sık diğer servislerinden gelen hastalarda görüldü (%48). Skorlama sistemlerinin ortalama değerleri, ölenlerde yaşayanlardan anlamlı olarak yüksekti ancak standardize edildiğinde skorlama sistemleri arasında anlamlı fark yoktu. Yandaş hastalıklardan jinekolojik, hematolojik, respiratuvar maligniteler ve gastrointestinal sistem hastalıklarında mortalite anlamlı olarak yüksek idi (p0,05). Yapılan lojistik regresyon analizinde; acil servisten kabul ve yoğun bakımda yatış süresi ile mekanik ventilasyon süresi uzun olan hastalarda mortalite riskinin arttığı görülmüştür. En doğru mortalite tahmini, sırasıyla, SAPS III>APACHE II>APACHE IV olarak gözlendi.Sonuç olarak; sınırlı hasta sayısına rağmen SAPS III ve APACHE II sisteminin APACHE IV'ten daha iyi mortalite tahmininde bulunduğu sonucuna vardık.Anahtar kelimeler: yoğun bakım, skorlama sistemi, mortalite, SAPS III, APACH
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.
