    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    China and the Darfur Crisis

    Darfur is Sudan’s western region, and the site of one of the major crises of the early 21st Century that dominated world affairs from 2003 to 2009.  The Darfur Crisis competed for world attention with major contemporary issues such as the US invasion of Iraq, the War on Terror, the US presence in Afghanistan, the Arab-Israeli Conflict, the Kosovo crisis and the civil war in Democratic Republic of Congo.  China was largely held responsible for the overwhelming level of force utilized by the Sudanese Government in quelling peaceful protests in the region in spring and summer of 2003.  Its oil interests in the Sudan were identified as the main catalyst for its siding with the Sudanese government and shielding it from punitive measures by the international community. Other catalysts include trade relations and arms sales to Sudan. The objective of this article is to examine China’s policy and role in the management of the Darfur Crisis over the past ten years. It’s based on the thesis that, China’s lenient policy toward the Sudanese government, driven by its oil interests has encouraged the Sudanese government to utilize overwhelming force against Darfur’s legitimate protest with impunity

    Variations on the Author

    “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

    We 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 PDF
    We 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

    The Geopolitics of the North African Response to the Coronavirus Pandemic: Opportunities and Challenges

    Get PDF
    The sudden outbreak of the Coronavirus in January 2020 took the world by surprise. Initial state-response was mired by confusion, uncertainty, apprehension, and near demoralization. However, several countries around the world, including some Middle Eastern and North Africa countries (MENA) took the challenge seriously in the early stages and set an example to be emulated globally. The objective of this article is to examine the response of the North African countries to the pandemic, examine the opportunities and the challenges facing the region, and add up the lessons learned in order to be better prepared for impending crises facing the nation-state, the region at large, and the international community. This survey article seeks to highlight the common denominators whenever possible and examine country-specific conditions that determine the success or the failure in dealing with the Corona Crisis in Middle East and North Africa
