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
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
Новые технологии в лечении больных с приобретенными дефектами и деформациями лицевого черепа
Get PDFMore than 15 patients with the isolated fracture of the bottom wall of an orbit as «blow-out» were studied. As one of variants of an individual approach to restoration of the isolated defects of the bottom wall of an orbit we had been offered a technique of a osteo-plastic antrotomy, as a stage of access. All patients have been taken on a dispensary observation. According to the lead postoperative computer tomography of additional sinuses of a nose in two projections, and also ortopantomography, rentgenographies of a facial skull in direct and lateral projections, endoscopic research, the pneumatization of the operated genyantrums has not been disturbed, the osteal forward wall has been kept on all extent, was absent retraction soft tissues of infraorbital area, integrity of an osteal wall of a bottom of an orbit has been restored, that as a whole speaks about efficiency and not so traumaticaly the lead surgical treatment. The offered way of surgical treatment promotes to the greatest degree to conservation of anatomic structures of maxillofacial area, possessing the least traumatism in comparison with other ways. This technique is simple, effective and does not demand application of the expensive equipment.Обследовано 15 больных с изолированным переломом нижней стенки глазницы по типу «blow-out». В качестве одного из вариантов индивидуального подхода к восстановлению изолированных дефектов нижней стенки глазницы нами была предложена методика костно-пластической антротомии как этап доступа. Все больные были взяты на диспансерное наблюдение. По данным проведенной послеоперационной компьютерной томографии придаточных пазух носа в двух проекциях, а также ортопантомографии, рентгенографии лицевого черепа в прямой и боковой проекциях, эндоскопического исследования, пневматизация оперированных верхнечелюстных пазух не была нарушена, костная передняя стенка была сохранена на всем протяжении, отсутствовало пролабирование мягких тканей подглазничной области, целостность костной стенки дна глазницы была восстановлена, что в целом говорит об эффективности и малотравматичности проведенного хирургического лечения. Предлагаемый способ хирургического лечения способствует в наибольшей степени сохранению анатомических структур челюстно-лицевой области, обладая наименьшим травматизмом по сравнению с другими способами. Эта методика проста, эффективна и не требует применения дорогостоящего оборудования
Хирургическое лечение больных с переломами нижней стенки глазницы
Get PDFAuthors report their experience in the treatment of fractures involving the orbital floor. A total of 14 patients passed pre and post-operative clinical and radiological assessment. Of the 14 patients, the zygomatic-maxillary-orbital complex was involved in 6, isolated fractures of the orbital floor blow-out in 8. In all the cases transantral approach was used. In fractures involving the zygomatic-maxillary-orbital complex, apart from repair of the orbital floor, fixation of «standard» junctions points was made. In isolated fractures of the orbital floor blow-out, «bone-plastic antrotomy» method was used. This one may be defined as variant of classical antrotomy what dont leave bone defect on the frontal wall of the maxillary sinus. In all the cases titanium material was used for osteosynthesis: mini-plates or mesh. The last one was employed in four patients due to substantial bone loss. Functional and aesthetic deficits were resolved in all patients. Long-term results showed complete recovering of binocular eyesight and absence of enophthalmos.Настоящая работа отражает наш опыт хирургической реабилитации больных с переломами нижней стенки орбиты. Проведено клинико-рентгенологическое обследование до и после операции у (14) пациентов с повреждением дна орбиты в изолированном виде и в контексте травмы скулоорбитального комплекса. Отмечено превалирование изолированного вида травмы (57,14%) у мужчин молодого возраста (78,57%). Во всех случаях в качестве хирургического доступа к нижней стенке глазницы использовали трансантральный доступ. При повреждении дна орбиты в сочетании с травмой скулоорбитального комплекса, помимо репозиции дна орбиты, скуловой комплекс фиксировали в трех стандартных точках. В случае изолированного повреждения, т.е. при наличии перелома, типа чистого «blow-out», применяли метод костно-пластической антротомии как вариант трансантрального доступа, не оставляющий дефекта на передней стенке верхнечелюстной пазухи. Во всех клинических наблюдениях был использован титановый материал для остеосинтеза: ф-образные минипластины, или индивидуально смоделированные титановые сетки при более обширных дефектах. У всех пациентов удалось устранить функциональные и эстетические нарушения, возникшие после травмы: отдаленные результаты показали полное восстановление бинокулярного зрения и отсутствие энофтальма
