Medallions of Huviška as pictorial evidence of pre-Islamic lamellar helmets
Get PDFIn the current paper the author discusses headgear represented on Kušān medallions showing the bust of King Huviška. Most likely those medallions are depicting pre-Islamic lamellar helmets, well known from for example on the Sasanian, Bīsetūn capital currently held in Ṭāq-e Bostān Museum, Iran. The author will try to compare the presented lamellar constructions with known finds of such helmets of the pre-Islamic er
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
The Kizil Caves as an terminus post quem of the Central and Western Asiatic pear-shape spangenhelm type helmets. The David Collection helmet and its place in the evolution of multisegmented dome helmets
Get PDFCurrent paper consists of two main parts. In the first part the author discusses arms and armor presented in the Kizil Caves depictions, suggesting a datation of the two well-known caves, namely so-called Maya Cave and Cave of the Painter. In the second part of this paper the author discusses a helmet found in Iran and currently held in the David Collection, Copenhagen. On the basis of a detailed comparative analysis, the author puts forward a thesis of correlation between the lamellar and spangen pear-shape helmets dating the objects to late 6th beginning of the 7th century CE. Specifically, it is suggested that the David Collection helmet is a later evolution of such forms that was known in the late-Sasanian period

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
Introduction to studies on late Sasanian protective armour. The Yarysh-Mardy helmet
Get PDFThe article discusses a helmet found in 1968 in a mountainous village of Yarysh-Mardy situated on the river Argun in the north-eastern Caucasus. The helmet was often associated with the Golden Horde period, which according to the author seems highly unlikely. On the basis of a detailed comparative analysis, the author puts forward a thesis of dating the object to either the late-Sasanid or early-Islamic period, i.e. to late 6th- beginning of 8th c. AD. Specifically, it is suggested that the appearance of the helmet in the Caucasus may be attributed to the time of Byzantine-Sasanid conflicts taking place at the turn of 6th and 7th c. AD. Additionally, the article argues that in the late Sasanid period a new sub-type of helmets came into existence, namely the ones with straight spangs and ones with spiky rivets. Furthermore, it is proposed that the Yarysh-Mardy helmet bears certain correspondences to similar finds from Groningen and Bremen
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
