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
Development and Validation of an Instructor Course Evaluation (ICE) System at the American University of Beirut
No full textتصف هذه الدراسة كيفية تطوير نظام جديد لتقويم الأستاذ والمقرر في الجامعة الأمريكية في بيروت، من خلال تطوير نسختين: الكترونية وورقية، ولقد تم تطبيق الأداة خلال العام الدراسي 2003 في كل الكليات، وجرت مقارنة النسختين من حيث نسب الإجابة والثبات، وقد تم التأكد من الصدق من خلال إجراء التحليل المعاملي، بالإضافة إلى دراسة أثر بعض الخصائص المؤثرة في تقدير الطلاب. وقد أظهرت النتائج أن النسختين تتمتعان بثبات داخلي عال ، ولكن نسب الإجابة في النسخة الالكترونية كأنت منخفضة، كما أظهر التحليل العاملي وجود عاملين أساسيين يقيسان فعالية الأستاذ والمقرر أما نتائج دراسة العوامل المؤثرة فقد أظهرت تطابقا مع الأدبيات حول الموضوع وأكدت صدق الأداة ، وأوصت الدراسة بالتوقف المؤقت عن استعمال النسخة الالكترونية وذلك لضعف نسب الإجابة، كما قدمت توصيات للقيام بأبحاث مستقبلية لتطوير الأداة.This study describes the development of a paper and an on-line version of a new instructor course evaluation (ICE) system at the American University of Beirut, Lebanon. The ICE was administered in spring and fall 2003 to students in all faculties. Both versions were compared with respect to response rates and reliabilities. In addition, the validity of the paper version was investigated using factor analysis and the effect of certain 'biasing' characteristics on student ratings was examined. The results revealed that both versions had similar high internal consistency reliabilities; however, the response rate on the on-line version was much lower. Factor analysis of responses revealed two factors measuring instructor and course effectiveness. Investigation of the effect of certain 'biasing' characteristics on student ratings was in agreement with those reported in the literature and confirmed the validity of the ICE. Because of low response rate, the on-line version was temporarily discontinued and recommendations for further research were presented
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
The alignment between the fourth grade Lebanese science curriculum and classroom assessments
Get PDFThe purpose of this study was to investigate the alignment between the fourth-grade summative classroom assessments and the ‘Matter and Energy’ unit in the Lebanese science curriculum using: content and cognitive levels. Summative assessments were collected from a sample of 17 schools. The alignment between the classroom assessments and the Lebanese science curriculum were examined using three instruments: Curriculum Coding Sheet, Items Coding Sheet, and Item Analysis Sheet. The curricular learning objectives were used for matching the test items to the learning objectives in terms of content. Findings showed moderate content alignment; further analysis revealed that public schools had higher content alignment, and they covered a wider range of topics. In terms of cognitive level, there was a low alignment between the assessments collected and the curriculum; however, there were items that had higher cognitive level. Recommendations for curriculum developers and future research are discussed in light of these findings. © 2018, © 2018 ASPE
استطلاع آراء المدرسين والمدراء حول الاستبقاء
No full textThis study surveyed teachers' and principals' views on grade retention in grades K-13. 833 teachers and principals, a sample representative of the school population in Lebanon, were asked to fill out a questionnaire on their opinion of the practice, the reasons for retention, the characteristics of the retained and on who should make the retention decision. The results revealed those teachers and principals overwhelmingly supported grade retention and believed that the retention decision should be made jointly by teachers and principals. With respect to the characteristics of the retained, "low concentration" was the characteristic most often marked, followed by " low motivation" and "low intelligence". As to the reasons for retention, "overall academic weakness" was the reason most often cited, followed by "lack of basic skills" and "excessive absences". Differences between the views of the teachers and the principals and the effect of background variables like type of school, geographic location, years of experience, subjects
and grades taught, and language of instruction were also investigated.تم استطلاع أراء مدرسي ومدراء بعض المدارس حول الاستبقاء أو إعادة الطالب لصفة ، وقد شمل هذا الاستطلاع كافة مراحل الدراسة من صف الروضة حتى الصف الثالث عشر ، وتكونت عينة الدراسة من ٨٣٣ مدرس ومدير مدرسة مثلت واقع المجتمع الدراسي في لبنان، طبق عليهم استبيانا لمعرفة آرائهم حول هذا الإجراء، والأسباب التي تقف وراء الاستبقاء ،كذلك خصائص الطلبة الذين تم استبقائهم، ولمن يعود حق اتخاذ هذا القرار . وقد أظهرت النتائج أن الغالبية العظمي من المدرسين ومدراء المدارس يؤيدون الاستبقاء ويعتبرون أن اتخاذ القرار بشأنه يجب أن يكون بناء علي قرار مشترك بين المدرس ومدير المدرسة علي حد سواء ، وحول الخصائص التي يستند إليها قرار الاستبقاء ، وجد أن "الضعف في التركيز" يأتي في المرتبة الأولي يعقبه " قلة الاهتمام " ثم بطئ الاستيعاب أما عن أسباب الاستبقاء ، فأكثر الاستجابات وضعت ضعف المجموع العام كسبب أول ، يليه غياب المهارات الأساسية، ثم كثرة غياب الطالب . ويتطرق هذا البحث أيضا إلي التباين في وجهات نظر مدرسي ومدراء المدارس وذلك بحسب المتغيرات المتعلقة بالخلفية ، مثل فئة المدرسة والموقع الجغرافي ، وسنوات الخبرة ، ومواد التعليم ، والصفوف التي تدرس ، وكذلك لغة التدريس
