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
Guerra santa y órdenes militares ibéricas (1150-1250)
No full textThis article analyzes the role of the Iberian military orders in the holy war against Muslims (1150-1250).

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

MASA KEMUNDURAN (1250-1500 M)
No full textThe history of Islamic civilization, particularly the period of decline (1250–1500 AD), remains a significant field of study attracting scholars from both Muslim and non-Muslim backgrounds. Studying the history of Islamic civilization and culture allows for a deeper understanding of Islam’s golden eras, which fosters a sense of pride and confidence within the Muslim community. This research employs a qualitative approach through a comprehensive literature study. This methodology enables the author to systematically analyze and address research problems by drawing from highly credible sources, including authoritative books and reputable journal articles. The findings suggest that the 1250–1500 AD period was an era of profound challenges for the Islamic world, characterized by a series of events that impacted political, economic, and intellectual landscapes. Despite this decline, Islamic civilization successfully preserved the continuity of its scientific and cultural heritage, providing a crucial foundation for future developments even under adverse condition
