ISO/IEC 19788-1: A metadata framework
No full textInternational audienceThe ISO/IEC 19788 family, also known as Metadata for Learning Resources, was created to categorize resources in learning, education, and training contexts. It comprises various parts, such as Part 1: Framework (19788-1), initially specifying how to describe learning resources. Its broader applications have made it a horizontal standard for all ISO/IEC JTC1 standards groups promoting the interoperability of descriptions. The paper, written by editors of the standard, overviews 19788-1’s most essential aspects focusing on its underlying principles (such as multilingual or cultural diversity or technical neutrality) and the specification of entities involved in the description of resources (such as properties or application profiles), leaving out less pertinent details for a general presentation
The international standard ISO/IEC 19788: metadata for learning resources: creating a unified Arab educational metadata standard
Get PDFيهدف هذا البحث إلى دراسة المعيار الدولي ISO/IEC 19788 (Metadata for Learning Resources) وطريقة استخدامه لإنشاء معيار ميتاداتا تعليمي عربي موحد. سنتناول في الجزء الأول من البحث تعريف الميتاداتا التعليمية مع التركيز بشكل خاص على دراسة المعيار دبلن كور والمعيار LOM وسنستعرض في الجزء الثاني أهم خصائص ومميزات المعيار ISO/IEC 19788 وفي الجزء الأخير سنتناول بالدرس والتحليل أهم الخصوصيات التعليمية والثقافية واللغوية التي تميز العالم العربي والتي يجب أخذها بعين الاعتبار في إطار معيار عربي موحد لوصف المصادر التعليمية الرقمية. This research aims to study the international ISO/IEC 19788 standard and the method used to createa unified Arab educational metadata standard. In the first part, we will discuss the definition ofeducational metadata with a particular focus on the standard Dublin Core and the standard LOM. Inthe second part, we will review the most important characteristics and advantages of ISO / IEC19788 standard. In the last part, we will discuss and analyze the most important educational,cultural and linguistic characteristics of the Arab world and which must be taken into considerationwhen creating an Application Profile to describe digital educational resources
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
