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

A questionnaire measuring parental involvement, homework and T.V. watching was used in addition to Family Environment Scale, as translated by the first author, Step-wise regression was used to calculate path coefficients. Results show that there are significant direct and indirect effects for 5 family variables, 4 personality traits, parental in¬volvement, homework and T.V. watching on achievement
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
The Liischer Color Test as a measure of Personality For Egyptian and Qatari Samples.
No full textتهدف هذه الدراسة إلى التأكد من مدى ثبات وصدق اختبار لاشر للألوان بالإضافة إلى مدى وجود اختلافات بين أسماء الألوان كما يحددها الاختبار وأسمائه كما تحددها عينة مصرية وأخرى قطرية، وكذلك مدى اختلاف تفضيل المفحوصين للألوان وذلك في حالات: التفضيل من بين ألوان الاختبار عند رؤيتها وعدم رؤيتها، والتفضيل الحر، وتم حساب معامل ثبات الاختبار كمقياس للشخصية بطريقتين وكان 0.48 (كمقياس للقلق) 0.57 للعينة المصرية، 0.62 للعينة القطرية، وكان صدقه كمقياس للقلق 0.12 ،0.17، 0.06 للعينة المصرية، 0.33،0.41،0.28 للعينة القطرية. بينما كان صادقاً كمقياس للشخصية مع اختبار كامل، كما اتضح عدم وجود اختلافات بين أسماء الألوان كما يحددها الاختبار وأسمائه كما حددتها عينة البحث كما وجدت اختلافات في تفضيل المفحوصين للألوان طبقاً لطريقة التفضيل المستخدمة.This study aims to verify the reliability and validity coefficients of the Luscher Color Test (LCT) Using an Egyptian and a Qatari Samples and to show the differences between the names of the colors as pointed out in the LCT, and the names as pointed out by the sample, and to show the differences in color preferences in the case of choosing from the LCT colors (seen & unseen) and in the case of free choice. Results show that the LCT was reliable and valid only as a mearure of personality. There were no differences between the two cases of naming the colors, but there were significant differences in color preferences in the three cases of choice
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
