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
Challenges in Teaching Mathematics and Ways to Overcome Them: Perspectives of Early Childhood Teachers
Full text linkهدفت هذه الدراسة إلى الكشف عن التحديات التي تواجهها معلمات الطفولة المبكرة في تدريس الرياضيات وطرق تجاوزها من وجهة نظرهن. ولتحقيق هدف الدراسة، استخدم الباحثون المنهج الوصفي المختلط (كمي ونوعي)؛ فعُقدت مقابلات مع (53) معلمة لجمع البيانات النوعية، وطُوّر استبيانان لجمع البيانات الكمية بعد توزيعهما على عينة مكونة من (238) معلمة في الأردن في العام الدِّراسي 2019/2020. وأظهرت نتائج الدِّراسة أنَّ مستوى التحديات التي تواجهها معلمات الطفولة المبكرة في تدريس الرياضيات جاء بدرجة متوسطة، في حين جاء مستوى الطرائق المناسبة لتجاوز التحديات بدرجة مرتفعة. كما أظهرت النتائج عدم وجود فروق دالة إحصائيًا تعزى إلى متغيرات: مستوى الصف، ونوع المدرسة، وفرع الثانوية، والمعدل في الثانوية، في حين توجد فروق دالة إحصائيًا تُعزى إلى متغير تخصص المعلمة في البكالوريوس، ولصالح تخصص معلم الصف. كما كشفت نتائج البيانات النوعية العديد من التحديات التي تواجه المعلمات في تدريس الرياضيات، ككثرة أعداد الطلبة في الغرفة الصفية وعدم مناسبة البيئة التعليمية. وأشارت هذه البيانات النوعية إلى مقترحات عديدة لمواجهة تحديات تدريس الرياضيات، كتوظيف الموسيقى والدراما والمسرح في تدريس الرياضيات. وفي ضوء نتائج هذه الدراسة، نوقشت مجموعة من التوصيات.This study aimed to explore the challenges that early childhood teachers face in teaching mathematics and ways to overcome them from their perspectives. To achieve the study aim, the researchers used the mixed descriptive approach (quantitative and qualitative). Interviews were conducted with (53) female teachers as a study instrument to obtain qualitative data, and two questionnaires were developed to obtain quantitative data after distributing them to a sample of (238) female teachers in Jordan in the academic year of 2019/2020. The study results showed that the level of challenges that early childhood teachers face in teaching mathematics was moderate, while the level of appropriate methods for overcoming the challenges was high. The results also showed that there were no statistically significant differences attributed to the variables: grade level, school type, high school branch, and GPA in high school, while there were statistically significant differences due to the variable of the teacher's specialization in the bachelor’s degree, in favor of the specialization of classroom teacher. The results of the qualitative data revealed many challenges that teachers face in teaching mathematics, such as the large number of students in the classroom and the inadequate educational environment. In addition, they indicated many suggestions to face the challenges of teaching mathematics, such as employing music, drama, and theater in teaching mathematics. In light of the study results, several recommendations were 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
Evaluating social and national education textbooks based on the criteria of knowledge-based economy from the perspectives of elementary teachers in Jordan
No full textAbstractKnowledge-based economy is a new implemented trend in the field of education in Jordan. The ministry of education in Jordan attempts to implement this trend's philosophy in its textbooks. This study examined the extent to which the (1st – 3rd grade) social and national textbooks reflect knowledge-based economy criteria from the perspective of Jordanian teachers. The quantitative questionnaire addressed five evaluation criteria of knowledge-based economy that incorporate 40 evaluation aspects. The main findings highlighted that the content of the social studies textbooks does not refer to the philosophy of knowledge-based economy directly. More attention to the thinking skills criterion is needed
