Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Silver rings and marten skins : Contacts between the Volga Region and the Baltic in the early Viking Age
No full textViking Age silver is a useful tool for tracing various aspects of the society. Contact networks, trade organization, society structure, economic variation etc. This paper concentrates on the so-called Permian rings, which appear in Scandinavian silver hoards from Early Viking Age. Their main concentration is, however, in the regions west of the Ural Mountains in Russia. As the rings found in Russia and in Scandinavia are similar or even almost identical, the current hypothesis has been that the Scandinavian items were imported from the East. In this article I scrutinise rings from museum collections in Russia, Scandinavia and the Baltic Region, in all xx . Some details, especially stamped decoration, only occur on rings found in Scandinavia and around the Baltic sea, indicate that some rings were actually made in that region. Characteristic for this type of rings is, that they were made according to settled weights, usually around 200 100 grams. This is probably an indication that the rings are not only ornaments but also some kind of money in large units. There are many indications that Scandinavians took part in activities in the East in Early Viking Age. The region northeast of Volga and around the Kama river fur trade to Sassanian, Abbasid and Byzantine realms seems to have played an important role. For example exquisite silver vessels from these areas are quite abundant in the north. The organization for purchasing furs in the north may be visualised as fur animals were hunted by many small groups of trappers and brought to centres along the rivers. The abundant traces of metal handicraft at these sites might have been aiming at producing commodities to pay them. Furs were collected and concentrated at the centres. Furs were then traded towards the South at big scale probably with silver involved. Weight adjusted silver rings would have been a convenient means of payment than coins in this large-scale trade. The rings of Perm type found in Scandinavia and the Baltic region indicate that Scandinavians took part in the activities, probably some kind of middlemen and brought so of their profit back home. The Eastern rings, however, also inspired to production in their new surroundings. The Baltic/Scandinavian rings with stamped decoration show that besides coins and hack-silver there was also a need for large unit means of payment. Interesting is, that while Eastern rings are well known in the West, that western, stamped decorated rings are not known from the Eastern regions. That the rings, besides being ornaments, also had an economic function is indicated by their weights. Their weights is in accordance to the Carolingian pound, Scandinavian medieval mark weight, then old Russian pound with roots in Sassanian drachms, Arab dirhams and ultimately in Byzantine and Roman weight systems. The importance of pure silver was of outmost importance when used as means of payment. Silver items were tested, probably to scrutinize the quality. There are also various examples of purifying silver in late Viking Age Scandinavia. When larger amounts of silver were handled it was more secure to use big rings, where the silver easily could be tested, than a great number of small items
