Physical barriers, cultural connections: a reconsideration of the metal flow at the beginning of the metal age in the Alps
Get PDFThis thesis considers the early copper and copper-alloy metallurgy of the entire Circum-Alpine region. It introduces a new approach to the interpretation of chemical composition data sets, which has been applied to a comprehensive regional database for the first time. An extensive use of GIS has been applied to investigate the role of topography in the distribution of metal and to undertake spatial and geostastical analysis that may highlight patterns of distribution of some specific key compositional element. The Circum-Alpine Chalcolithic and Early Bronze Age show some distinctively different patterns of metal use, which can be interpreted through changes in mining and social choices. But there are also some signs of continuity, in particular those which respect the use of major landscape features such as watersheds and river systems. Interestingly, the Alpine range does not act as a north-south barrier, as major differences in composition tend to appear on an east-west axis. Conversely, the river system seems to have a key role in the movement of metal. Geostastical analyses demonstrate the presence of a remelting process, applicable also in the case of ingots; evidence that opens new and interesting questions about the role of ingots and hoards in the distribution of metal at the beginning of the Metal Age. New tools and new analysis may also be useful to identify zones where there was a primary metal production and zones where metal was mostly received and heavily manipulated
Presenting Counterpoints to the Dominant Terrestrial Narrative of European Prehistory
Get PDFThe first in the multi-author series Maritime Encounters, outputs of the major six-year (2022–2028) international research initiative, funded by Sweden’s central bank. Our programme is based on a maritime perspective, a counterpoint to prevailing land-based vantages on Europe’s prehistory. In the Maritime Encounters project a highly international cross-disciplinary team has embarked on a diverse range of research goals to provide a more detailed and nuanced story of how prehistoric societies realised major and minor sea crossings, organised long-distance exchange, and adapted to ways of life by the sea in prehistory.
Recent advances with ancient DNA have brought migration back into archaeological explanation, but little attention has been paid to maritime aspects of these movements or the maritime legacies inherited from indigenous cultures.
The formation of the populations, cultures and languages of Europe are now seen largely as consequences of three great prehistoric migrations: hunter-gatherers repopulating the post-glacial landscape, followed by farmers spreading from
Anatolia, and then Indo-European-speaking pastoralists from the steppe.
There is a significant gap in this current model that we sense most acutely in Scandinavia and the British Isles. Unanswered questions include: How these groups reached the islands and peninsulas of Atlantic Europe? What types of boats were
used? How many people and animals could they carry? To what extent did indigenous coastal peoples contribute traditions and knowledge of boats, boat building, seaways, navigation, and subsistence in coastal environments. How
was the long-distance trade in metals organised during the European Bronze Age? And what was the impact of this seacrossing network on the cultures, languages, and populations of the producers and consumers of bronze

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
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
