Introduction: approaching invisible circular economies through archaeological and historical sources
No full textEconomic Circularity in the Roman and Early Medieval Worlds. New Perspectives on invisible agents and dynamics
No full textEconomic circularity is the ability of a society to reduce waste by recycling, reusing, and repairing raw materials and finished products. This concept has gained momentum in academia, in part due to contemporary environmental concerns. Although the blurry conceptual boundaries of this term are open to a wide array of interpretations, the scholarly community generally perceives circular economy as a convenient umbrella definition that encompasses a vast array of regenerative and preservative processes.
Despite the recent surge of interest, economic circularity has not been fully addressed as a macrophenomenon by historical and archaeological studies. The limitations of data and the relatively new formulation of targeted research questions mean that several processes and agents involved in ancient circular economies are still invisible to the eye of modern scholarship. Examples include forms of curation, maintenance, and repair, which must have had an influence on the economic systems of premodern societies but are rarely accounted for. Moreover, the people behind these processes, such as collectors and scavengers, are rarely investigated and poorly understood. Even better-studied mechanisms, like reuse and recycling, are not explored to their full potential within the broader picture of ancient urban economies.
This volume stems from a conference held at Moesgaard Museum supported by the Carlsberg Foundation and the Centre for Urban Networks Evolutions (UrbNet) at Aarhus University. To enhance our understanding of circular economic processes, the contributions in this volume expand the framework of the discussion by exploring circular economy over the longue durée and by integrating an interdisciplinary perspective. Furthermore, the volume gives prominence to classes of material, processes, agents, and methodologies generally overlooked or ignored in modern scholarship
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
Seeking the invisible with legacy data: notes on the use of archives for the study of ancient circular economies
No full textVariations 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
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
