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
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
Особливості форми та розмірів нижньої щелепи та нижнього зубного ряду з урахуванням статі та краніотипу
No full textThe aim of the study: establishment of actual intravital craniometric characteristics of the shape and dimensions of the mandible and lower dentition of an adult person depending on gender and craniotype.
Research materials and methods: the work used dry bone preparations of whole or fragmented human skulls of both sexes in the amount of 39 units, from the collection of the Department of Human Anatomy of the Kharkiv National Medical University, and the results of CT studies of the head of adult people without existing bone tissue pathologies, totaling 85 observations. The basis of establishing a craniotype is the principle of calculating the general facial or facial index, which allows classifying anatomical objects according to the shape of the head structure.
Research results: the straight length of the mandible in adult leptoprosops males is from 88.5 mm to 102.4 mm, for women - from 86.3 mm to 100.7 mm; in mesoprosops men, this parameter gradually decreases to the level - from 81.3 mm to 95.7 mm, in women - from 80.7 mm to 94.9 mm; in euryprosops, the index is the smallest and ranges from 79.7 mm to 91.5 mm in males and from 78.5 mm to 90.8 mm in females. The opposite trend with significant ranges of variation is established for the angular width of the bone. Thus, in male leptoprosops, this parameter was determined from 84.6 mm to 97.5 mm, in female representatives - from 83.6 mm to 96.3 mm; in mesoprosops men, it increased from 89.1 mm to 105.3 mm, in women - from 87.9 mm to 103.1 mm; in euryprosops, regardless of sex, it reached its peak values, from 94.5 mm to 116.1 mm and from 92.7 mm to 114.1 mm, respectively. The height of the mandibular body also showed a certain dependence on the type of skull structure, in leptoprosops men it tended to the highest values and was fixed at the level from 29.1 mm to 38.9 mm, as well as in women - from 27.5 mm to 37.8 mm; at the same time, in mesoprosops men, the size decreased from 25.9 mm to 36.3 mm, in women, in turn, from 24.6 mm to 35.1 mm; in euryprosops men, this parameter ranged from 22.3 mm to 33.1 mm, and next to women - from 21.9 mm to 31.9 mm, it was at the level of the lowest indicators. When analyzing such a complex and multidirectional parameter as the arch of the mandible, it was also possible to obtain a characteristic of its dependence on the type of structure of the facial department of the skull. It was established that the range with the smallest values of the length of the arc is characteristic of leptoprosops, ranging from 135.8 mm to 149.4 mm in males and from 133.5 mm to 147.3 mm in females; average indices are characteristic of men - from 139.1 mm to 154.6 mm and women - from 136.4 mm to 151.2 mm with a mesoprosopic craniotype; in euryprosops of both sexes, the index tends to the greatest values at the level of 141.2 mm to 158.3 mm and from 139.7 mm to 155.7 mm, respectively.
Conclusions: the main craniometric parameters of the mandible are significantly dependent on the type of structure of the facial department of the skull. Thus, the leptoprosopic craniotype is characterized by maximum values of longitudinal and height dimensions with minimal indicators of width and arc length. Mesoprosops are characterized by the definition of intermediate, averaged values equidistant from marginal, terminal forms. In representatives with the euryprosopic type of skull structure, a significant decrease in the length and height of the jaw with a significant increase, up to the maximum values, width and length of the arch was observed. At the same time, unlike leptoprosops, which had a shortened and pointed arch, in euryprosops, the arch tended to be smoothed and lengthened. The assessment by sex leads to the fact that all sizes of the lower jaw predominate in men, but, nevertheless, a certain number of differences in indicators were within the limits of statistical error, which does not allow making absolute conclusions in this matterМета дослідження: встановлення актуальної прижиттєвої краніометричної характеристики форми та розмірів нижньої щелепи та нижнього зубного ряду людини зрілого віку в залежності від статі та краніотипу.
Матеріали та методи дослідження: в роботі використовували сухі кісткові препарати цілісного або фрагментованого черепа людини обох статей у кількості 39 одиниць, з колекції кафедри анатомії людини ХНМУ, та результати КТ-досліджень голови людей зрілого віку без існуючих патологій кісткової тканини, загальним об’ємом – 85 спостережень. В основу встановлення краніотипу покладено принцип обчислення загального лицевого або лицевого індексу, який дозволяє класифікувати анатомічні об'єкти за формами будови голови.
Результати дослідження: пряма довжина нижньої щелепи у чоловіків лептопрозопів зрілого віку складає від 88,5 мм до 102,4 мм, у жінок – від 86,3 мм до 100,7 мм; у чоловіків мезопрозопів, цей параметр поступово зменшується до рівня – від 81,3 мм до 95,7 мм, у жінок – від 80,7 мм до 94,9 мм; у еуріпрозопів покажчик найменшій та коливається від 79,7 мм до 91,5 мм – у чоловіків та від 78,5 мм до 90,8 мм – у жінок. Зворотна тенденція зі значними діапазонами коливань встановлена для кутової ширини кістки. Так, у лептопрозопів чоловічої статі, цей параметр визначався від 84,6 мм до 97,5 мм, у представниць жіночої статі – від 83,6 мм до 96,3 мм; у чоловіків мезопрозопів він збільшувався від 89,1 мм до 105,3 мм, у жінок – від 87,9 мм до 103,1 мм; у еуріпрозопів, незалежно від статі досягав своїх пікових значень, від 94,5 мм до 116,1 мм та від 92,7 мм до 114,1 мм, відповідно. Висота тіла щелепи, також демонструвала певну залежність від типу будови черепа, у лептопрозопів чоловіків вона прагнула до найбільших значень та фіксувалась на рівні від 29,1 мм до 38,9 мм, як і у жінок – від 27,5 мм до 37,8 мм; при цьому у мезопрозопів чоловіків, розмір зменшувався від 25,9 мм до 36,3 мм, у жінок, в свою чергу, від 24,6 мм до 35,1 мм; у чоловіків еуріпрозопів даний параметр мав коливання від 22,3 мм до 33,1 мм, і поруч з жінками – від 21,9 мм до 31,9 мм, знаходився на рівні найменших покажчиків. При аналізі такого складного та різнонаправленого параметру як дуга нижньої щелепи, також вдалось отримати характеристику його залежності від типу конструкції лицьового відділу черепа. Встановлено, що діапазон з найменшими значеннями протяжності дуги притаманний лептопрозопам, з коливанням від 135,8 мм до 149,4 мм у чоловіків та від 133,5 мм до 147,3 мм – у жінок; усередненні покажчики властиві чоловікам – від 139,1 мм до 154,6 мм та жінкам – від 136,4 мм до 151,2 мм з мезопрозопічним краніотипом; у еуріпрозопів обох статей, покажчик прагне до найбільших значень на рівні від 141,2 мм до 158,3 мм та від 139,7 мм до 155,7 мм, відповідно.
Висновки: основні краніометричні параметри нижньої щелепи знаходяться у значній залежності від типу будови лицьового відділу черепа. Так, для лептопрозопічного краніотипу характерні максимальні значення повздовжніх та висотних розмірів з мінімальними покажчиками ширини та протяжності дуги. Для мезопрозопів притаманне визначення проміжних, усереднених величин рівновіддалених від крайових, термінальних форм. У представників з еуріпрозопічним типом будови черепа простежено значне зменшення довжини та висоти щелепи із суттєвим зростанням, аж до максимальних значень, ширини та протяжності дуги. При цьому, на відміну від лептопрозопів, які мали скорочену та загострену дугу, у еуріпрозопів, дуга прагнули до згладженості та подовження. Оцінка за статевою ознакою призводить до констатації факту переважання всіх розмірів нижньої щелепи у представників чоловічої статі, але, все ж таки, певна кількість різниць показників знаходилась у межах статистичної похибки, що не дозволяє робити абсолютні висновки в цьому питанн

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.
