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
Local Economies? Production and Exchange of Inland Regions in Late Antiquity
No full textThe Roman economy was operated significantly above subsistence level, with production being stimulated by both taxation and trade. Some regions became wealthy on the basis of exporting low-value agricultural products across the Mediterranean. In contrast, it has usually been assumed that the high costs of land transport kept inland regions relatively poor. This volume challenges these assumptions by presenting new research on production and exchange within inland regions. The papers, supported by detailed bibliographic essays, range from Britain to Jordan. They reveal robust agricultural economies in many interior regions. Here, some wealth did come from high value products, which could defy transport costs. However, ceramics also indicate local exchange systems, capable of generating wealth without being integrated into inter-regional trading networks. The role of the State in generating production and exchange is visible, but often co-existed with local market systems
The Archaeology of late antique statue monuments
No full textHonorific statues did not only exist at the time of their dedication, as conceived by sculptors and letter-cutters. Rather, they were also moved, repaired, modified, neglected, and destroyed. This happened during what might be called their ‘statue life’, in which they went from being objects of memorial to artefacts of oblivion, in the same way as mausolea. The processes involved can be reconstructed from the archaeological study of statue monuments, especially the investigation of their context. This can also reveal a great deal more on the intentions of those who dedicated a statue, beyond what art history and epigraphy can demonstrate. In this paper, I set out the potential of a fully archaeological approach to these monuments, building on the strengths of the Oxford Last Statues of Antiquity project. In so doing, I give an additional perspective on the archaeology of memory in Late Antiquity, to that provided by the study of funerary monuments and their spoliation. I suggest that effort should be invested not just in studying the erection and removal of extant monuments but also those which we can surmise once existed. Thus, I seek to shift the study of public statuary away from describing the relics which survive, towards a historical consideration of how all such monuments were displayed and treated in Late Antiquity
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
