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
Dogme ELT: Oral Expression Teachers’ Perceptions
No full textThe present paper reports teachers’ opinions about the Dogme ELT Teaching Approach. It aims to know whether such as an approach can be used in developing students’ abilities to express themselves orally. This exploratory study was conducted by means of a semi-structured questionnaire administered to twenty (n=20) Oral Expression teachers at the Department of Foreign Languages, Section of English at Mohamed Kheider University of Biskra. The findings revealed that teachers appreciated teaching through conversation and focusing on emergent language, however, the majority refused minimizing the use of materials such as textbooks and technology, which they consider necessary in language teaching.

The Impact Of Computer Mediated Task-based Approach On Vocabulary Acquisition: The Case Of Third Year Secondary School Learners-sirin Lekhmissi Secondary School-souk Ahras
No full textنتج عن المزج بين مجالي الدراسة المعروفين بتعلم اللغات بمساعدة الكمبيوتر و التعليم القائم على المهمات ظهور إتجاه جديد في مجال تدريس اللغات والذي يدعى إكتساب المفردات في التعليم القائم على المهمات بمساعدة الكمبيوتر. تم طرح العديد من الأسئلة حول مدى نجاعة هذه الطريقة الجديدة لتدريس اللغات إذا ما تم إستعمالها في تدريس مفردات اللغة الأجنبية. بالتالي، يعد البحث الحالي محاولة لدراسة تأثير المقاربة القائمة على المهمات بواسطة الكمبيوتر على إكتساب المفردات لدى تلاميذ السنة الثالثة ثانوي بثانوية سيرين الخميسي-سوق أهراس. لهذا الغرض ، كانت أدوات جمع البيانات المستخدمة في هذا البحث التجريبي هي: استبيان مسبق واختبار مسبق واختبار آخر مع المجموعة التجريبية (15) ومجموعة الإختبار (15).على غرار عناصر مجموعة الاختبار تم تدريس المجموعة التجريبية مجموعة من المفردات عن طريق إختبارات المفردات و تطبيقات أخرى بإستعمال الكمبيوتر في إطار المقاربة القائمة على المهمات. أظهر تحليل نتائج المجموعة التجريبية نجاعة إستعمال المقاربة القائمة على المهمات مع تكنولوجيا الكمبيوتر لتحسين تعلم المفردات لدى الطلبة. لذلك يمكن اقتراح هذه المقاربة كإستراتيجية ليس فقط لتحسين مفردات المتعلم و انما لتدريس جوانب أخرى من اللغة الإنجليزية.The synergy of the two fields of study, computer assisted language learning and task-based language teaching resulted in the manifestation of a new trend of teaching called: computer mediated task-based teaching. Questions were raised about the extent to which this new approach can be effective if used in vocabulary instruction. Hence, the research in hand is an attempt to examine the effect of computer mediated task-based approach on vocabulary acquisition of third year secondary school learners from Sirin Lekhmissi Secondary School-Souk Ahras-. For this purpose, the data gathering tools used in this experimental research were: a pre-questionnaire, a pre-test and a post test with an experimental group (n=15) and a control group (n=15). The former, unlike the latter, was taught the target vocabulary through vocabulary quizzes and applications presented using the computer mediated task-based approach. The analysis of the findings revealed the significance of the instruction combining the task-based approach together with computer technology to improve learners’ vocabulary competence. Therefore, it is suggested as a strategy to develop not only learners’ vocabulary, but other aspects of the English language as well.La synergie des deux domaines d’études, l’apprentissage des langues assisté par ordinateur et l’enseignement des langues basé sur les tâches, a entraîné la manifestation d’une nouvelle tendance en matière d’enseignement appelée enseignement fondé sur des tâches informatisées. Des questions ont été soulevées sur la mesure dans laquelle cette nouvelle approche peut être efficace si elle est utilisée dans l'enseignement du vocabulaire. Par conséquent, la recherche en cours est une tentative pour examiner l’effet de l’approche basée sur les tâches médiatisée par ordinateur sur l’acquisition du vocabulaire des apprenants de troisième année du secondaire de l’école secondaire Sirin Lekhmissi - Souk Ahras-. À cette fin, les outils de collecte de données utilisés dans cette recherche expérimentale étaient: un pré-questionnaire, un pré-test et un post-test avec un groupe expérimental (n = 15) et un groupe témoin (n = 15). Les premiers, contrairement aux derniers, apprenaient le vocabulaire cible à l'aide de questionnaires de vocabulaire et d'applications présentées à l'aide de l'approche basée sur les tâches assistée par ordinateur. L’analyse des résultats a révélé l’importance de l’enseignement combinant l’approche par tâches et la technologie informatique pour améliorer les compétences en vocabulaire des apprenants. Par conséquent, il est suggéré comme stratégie de développer non seulement le vocabulaire des apprenants, mais également d’autres aspects de la langue anglaise
