Christograms on North African Lamps: considering context
No full textSummary: In this volume, twelve specialists examine the role of graphic signs such as cross signs, christograms, and monograms in the late Roman and post-Roman worlds and the contexts that facilitated their dissemination in diverse media. The essays collected here explore the rise and spread of graphic signs in relation to socio-cultural transformations during Late Antiquity and the early Middle Ages, focusing in particular on evolving perceptions and projections of authority. They ask whether some culturally specific norms and practices of graphic composition and communication can be discerned behind the rising corpus of graphic signs from the fourth to tenth centuries and whether common features can be found in their production and use across various media and contexts. The contributors to this book analyse the uses of graphic signs in quotidian objects, imperial architectural programmes, and a wide range of other media. In doing so, they argue that late antique and early medieval graphic signs were efficacious means to communicate with both the supernatural and earthly worlds, as well as to disseminate visual messages regarding religious identity and faith, and social power.

Villamagna in the Middle Ages
No full textBook synopsis: The evocative site of Villamagna, rising in lovely solitude against the steep wooded backdrop of the Monti Lepini, has enormous importance; but its imperial villa, known from the letters of Marcus Aurelius, has been largely ignored until recently, with interest focusing upon the medieval monastery that occupied the site. This volume presents the fascinating story of the site, from imperial villa, to a late antique successor, monastic complex, village, cemetery and late medieval castrum. Detailed, systematic study of the site and setting by non-invasive techniques and excavation has offered the scope to address a series of major questions; and the results are interpreted, setting them in the context of the documentary history of the site and its immediate neighbourhood, and of the broader history of central Italy, from around the first century through to the fourteenth. Each period of the site is considered separately, with the buildings described and the related finds (including pottery, glass, bones and environmental data) discussed. The volume will be of great importance for all scholars of Roman and medieval Italy
Introduction
No full textAmong the splendid cities of the world that have achieved celebrity, the city of
London – seat of the English monarchy – is one whose renown is more widespread,
whose money and merchandise go further afield, and which stands head and
shoulders above the others. It is fortunate in the wholesomeness of its climate,
the devotion of its Christians, the strength of its fortifications, its well-situated
location, the respectability of its citizens, and the propriety of their wives.
Furthermore, it takes great pleasure in its sports and is prolific in producing men

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
