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
Archaeological field survey - methods and problems
Full text linkThe advantages and disadvantages of field survey as a method for locating possible Stone and Bronze Age sites are described. Survey in the spring was favorable for finding Stone Age sites, while autumn survey was more successful for locating Bronze Age sites
Ture J:son Arne och vikingatiden i Östeuropa [Elektronisk resurs] : delar av ett forskarliv i 1900-talets Europa
No full textT. J. Arne (1879–1965) still stands out as the most important Scandinavian, perhaps Western European scholar working with the archaeology of early Russia. He was a person with a sharp and clear intellect, an impressive capacity to workwith rich archaeological collections and he was an outstanding linguist. He undertook three very ambitious research tours in Russia both before and after the revolutions. In connection with two of these tours he also excavated at important sites in Ukraine and in Russia. After the assumption of power of J. Stalin Arne became the leading scholar opposing the increasingly nationalistic and crude Marxist interpretations of what happened in the 9th and 10th centuries in Eastern Europe and more precisely in Russia. His scholarly achievements still today remain unchallenged and carry much weight.</p
Contacts, Identity and Hybridity : objects from South-western Finland in the Birka Graves
No full textThe study concludes that there were contacts between Birka and western Finland throughout more or less the whole existence of the town. The earliest evidence of these contacts is from the 760s and the latest from the middle of the tenth century. Unlike other eastern material in Birka, which became much more frequent during the second half of the ninth century the contacts with Finland were constant through time. However, the contacts might not have been very extensive compared to contacts with regions even further east. The study shows that, of the roughly 1,100 graves on Björkö, 13 contained costume details from Finland and 34 pottery of Baltic Finnish ware. The number of graves with objects from Finland amounts to roughly 4% of all the graves in Birka. However, it should be pointed out that this is the minimum amount since there might be pottery, especially coarse ware for cooking and storage, and objects with provenance from the Finnish mainland that cannot be singled out from local material or material from other regions. Interestingly enough, Finnish objects were most frequent in cremation graves under a mound, a form of grave that was very common in the Mälaren valley, and it is likely that the people who performed the funeral ritual followed local customs. However, a large share of objects from Finland occurred in chamber graves as well. This type of grave is believed to represent an elite of warriors and merchants with long-distance contacts. Some of the chamber graves with artefacts from Finland are also among the richest in Birka as regards the amount of grave goods. This shows that members in the leading circle in the town, men as well as women, were part of a network that had direct or indirect contacts with groups on the Finnish mainland. It is generally held impossible to identify ethnic groups based on the grave material in Birka. It is therefore suggested that migration to Birka as well as encounters taking place in the town prompted a dialogue in which different cultural elements were put together in an eclectic way and where local elements became entangled with foreign ones. It is likely that ethnic identities were played down in the town in favour of the construction and negotiation of new identities and affiliations
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
The archaeology of the Bronze Age cultural landscape - research goals, methods, and results
Full text linkThe article describes the methods used to determine Bronze Age peoples' use of the landscape in southern Scandinavia. The study is part of the Ystad Project, a large, interdisciplinary project with the aim of studying people and landscape from the advent of agriculture about 6000 years ago. Methods used included studies of archive data and maps, fieldwalking, and excavation. Results showed that the main settlement zone followed the coast, with only sporadic indications of activity further inland
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
