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
Шейный отдел позвоночника при болезни Шойермана: обзор литературы
Get PDFBackground. The state of the cervical spine in patients with Scheuermanns disease has still not been studied enough. This concerns the magnitude of cervical lordosis in the norm and in juvenile kyphosis in both pre- and postoperative periods, as well as the relationship of these changes with the spinopelvic parameters. There is almost no information on the correlation between the state of cervical lordosis and the development of proximal transitional kyphosis.
Aim of the study. To determine the features of the cervical spine in patients with Scheuermanns disease in the pre- and postoperative periods by analyzing the literature data.
Results. The literature data do not allow us to clearly define the limits of normal in the quantitative assessment of cervical lordosis. The only thing all researchers agree on is that the cervical lordosis should be considered discretely, namely at the C1-C2 and C2-C7 levels. The most commonly used parameters of the cervical-thoracic junction are T1 slope, thoracic inlet angle (TIA) and position of the sagittal vertical axis (SVA).
The magnitude of cervical lordosis in Scheuermanns disease varies from 4 to 35, i.e., thoracic kyphosis increase is not always accompanied by the development of compensatory cervical hyperlordosis. In thoracic deformities (the apex is at the level of T10 and cranial), the magnitude of cervical lordosis is significantly greater than that in thoracolumbar deformities (the apex is at the level of T11 and caudal). In the first case, the cervical lordosis (C2-C7) is 19.4-26.2, while in the second one 4.7-8.5.
Very few literature data demonstrate that in terms of cervical lordosis dynamics, patients with Scheuermanns disease do not represent a homogeneous group. The only pattern is that the cervical lordosis increases slightly in the longterm postoperative period. The spinopelvic parameters in patients with Scheuermanns disease differ little from the normal ones and almost do not change after corrective interventions. We could not find any publications attempting to relate the risk of PJK to cervical-thoracic junction parameters (T1, TIA, SVA).
Conclusion. The state of the cervical spine in patients with severe forms of Scheuermanns disease, subject to surgical correction, has not been studied enough. This concerns the magnitude of cervical lordosis, its dynamics in the postoperative period, its relationship with spinopelvic parameters, as well as the correlation between parameters of transitional cervical-thoracic spine and development of proximal transitional kyphoses. Further studies of this problem are needed.Актуальность. Состояние шейного отдела позвоночника у пациентов с болезнью Шойермана на настоящий момент изучено недостаточно. Это касается величины шейного лордоза в норме и при ювенильных кифозах как в до-, так и в послеоперационном периодах, а также связи этих изменений с позвоночно-тазовыми параметрами, Практически нет информации о корреляции состояния шейного лордоза с развитием проксимальных переходных кифозов.
Цель публикации на основании анализа литературы определить особенности состояния шейного отдела позвоночника у пациентов с болезнью Шойермана в до- и послеоперационном периодах.
Результаты. Данные литературы не позволяют четко очертить границы нормы при количественной оценке шейного лордоза. Единственное, в чем сходятся все исследователи, шейный лордоз следует рассматривать дискретно, а именно на уровнях С1С2 и С2С7. Наиболее часто используемыми параметрами шейно-грудного перехода являются наклон Th1 позвонка, наклон входа в грудную клетку (TIA) и положение сагиттальной вертикальной оси (SVA). Величина шейного лордоза при болезни Шойермана варьирует от 4 до 35, т.е. увеличение грудного кифоза далеко не всегда сопровождается развитием компенсаторного шейного гиперлордоза. При грудных деформациях (вершина на уровне Т10 и краниальнее) величина шейного лордоза значительно превышает таковую при грудо-поясничных деформациях (вершина на уровне Т11 и каудальнее). В первом случае шейный лордоз (С2С7) составляет 19,426,2, во втором 4,78,5. Весьма немногочисленные литературные данные демонстрируют, что в аспекте динамики шейного лордоза пациенты с болезнью Шойермана это не гомогенная группа, и единственная закономерность заключается в том, что в отдаленном послеоперационном периоде шейный лордоз незначительно увеличивается. Позвоночно-тазовые параметры у пациентов с болезнью Шойермана мало отличаются от нормальных показателей и практически не меняются после корригирующих вмешательств. Не удалось найти работ, в которых предпринята попытка увязать риск развития проксимального переходного кифоза с параметрами шейно-грудного перехода (Th1, TIA, SVA).
Заключение. Состояние шейного отдела позвоночника у пациентов с тяжелыми формами болезни Шойермана, подлежащими оперативной коррекции, изучено недостаточно. Это касается величины шейного лордоза, его динамики в послеоперационном периоде, связи с позвоночно-тазовыми параметрами, а также взаимозависимости параметров переходного шейно-грудного отдела с развитием проксимальных переходных кифозов. Необходимы новые исследования в этом направлении
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.
