Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Principles of Economics
No full textThe Arab World edition of N. Gregory Mankiw’s and Mohamed Rashwan, Principles of Economics is essential reading for economics students in Arab countries and those with an interest in Islamic finance. Using Mankiw’s classic ten principles approach to economics, the book provides students with a framework for understanding the economy of the world they live in. Written in an engaging and accessible style and designed to encourage students to think like an economist, the text equips them to engage confidently and critically with theories and principles of economics. Following on from the successful third edition, this text contains updated case studies, news articles and features that focus on the Arab world. This fourth edition is also available as a MindTap, a fully interactive learning platform with an interactive eReader, assessment questions, revision aids, engaging multimedia to explain key concept and further case studies. It also provides analytics to help you keep track of students’ progress
Petrography, geochemistry and petrogenesis of the MIGIF HAFAFIT GNEISSES at HAFAFIT MINE area, South Eastern Desert, Egypt
No full textThe present monograph by A.A. Rashwan is a major contribution to the Bilateral Cooperation in Geosciences between the Arab Republic of Egypt and the Federal Republic of Germany. The Egyptian Geological Survey and Mining Authority (EGSMA) represents the Egyptian side and the Geologisch-Palaontologisches Institut (GPI), Ruprecht-Karls-universitat, Heidelberg the German side. The cooperation project is sponsored by the Federal Ministry for Research and Technology (BMFT), Bonn, through the International Bureau of Forschungszentrum Jülich. The general aim of the cooperation project is to bring together the detailed regional knowledge of the Egyptian side with the general experience on tectonic and ore forming processes, and laboratory facilities of the German side. In particular, the project attempts to clarify the tectonic evolution of the Pan-African basement in the Eastern Desert of Egypt together with the formation and location of ore deposits. Towards that aim the present work by A.A. Rashwan is of eminent importance. For the first time, it gives a comprehensive compilation of petrographic, geochemical and petrological data for a suite of gneissic rocks, which forms, together with other areas of gneissic suites, a conspicuous element of the Pan-African basement. The data presented here show the gneissic suite to represent an igneous sequence starting from ocean floor ophiolites and leading to a calc-alkaline succession similar to modern island arcs. Elsewhere in the Eastern Desert ophiolites (ocean floor fragments)and calc-alkaline igneous rocks (island arcs) host the famous gold and base metal deposits. The present results, therefore, imply the gneissic rocks to be a promising target for future exploration of ore deposits. This latter work is now on its way and we are looking forward to see further results and their publication in the "Scientific Series" of the International Bureau. Last, but not least, we want to express our thanks for the generoussupport of the Bilateral Cooperation project by the Federal Ministry for Research and Technology, Bonn, and the International Bureau of Forschungszentrum Jülich
Variations on the Author
No full text“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
Seismic and Geodetic Crustal Moment-Rates Comparison: New Insights on the Seismic Hazard of Egypt
No full textA comparative analysis of geodetic versus seismic moment-rate estimations makes it possible to distinguish between seismic and aseismic deformation, define the style of deformation, and also to reveal potential seismic gaps. This analysis has been performed for Egypt where the present-day tectonics and seismicity result from the long-lasting interaction between the Nubian, Eurasian, and Arabian plates. The data used comprises all available geological and tectonic information, an updated Poissonian earthquake catalog (2200 B.C.–2020 A.D.) including historical and instrumental datasets, a focal-mechanism solutions catalog (1951–2019), and crustal geodetic strains from Global Navigation Satellite System (GNSS) data. The studied region was divided into ten (EG-01 to EG-10) crustal seismic sources based mainly on seismicity, focal mechanisms, and geodetic strain characteristics. The delimited seismic sources cover the Gulf of Aqaba–Dead Sea Transform Fault system, the Gulf of Suez–Red Sea Rift, besides some potential seismic active regions along the Nile River and its delta. For each seismic source, the estimation of seismic and geodetic moment-rates has been performed. Although the obtained results cannot be considered to be definitive, among the delimited sources, four of them (EG-05, EG-06, EG-08, and EG-10) are characterized by low seismic-geodetic moment-rate ratios (<20%), reflecting a prevailing aseismic behavior. Intermediate moment-rate ratios (from 20% to 60%) have been obtained in four additional zones (EG-01, EG-04, EG-07, and EG-09), evidencing how the seismicity accounts for a minor to a moderate fraction of the total deformational budget. In the other two sources (EG-02 and EG-03), high seismic-geodetic moment-rates ratios (>60%) have been observed, reflecting a fully seismic deformatio
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
