No full textHome Page: Welcome to the online publication of the Villa Magna Project (2006–10). Our work involved the excavation and survey of a large imperial Roman villa and its estate, known from the letters of Marcus Aurelius, and the subsequent life of the site—its fortification in late antiquity, and the creation of a monastery among the ruins in the 10th century. The project was sponsored by the University of Pennsylvania’s Museum of Archaeology and Anthropology (Mediterranean Section), the British School at Rome, and the Soprintendenza ai Beni Archeologici del Lazio, with core funding from the 1984 Foundation, the Comune of Anagni and the BancAnagni Credito Cooperativo.
This website includes the stratigraphic reports, object catalogues, physical anthropology, and environmental analyses for excavations at the site of Villa Magna, Italy. These materials are designed as a digital companion to the print volume Villa Magna: an Imperial Estate and its Legacies. Excavations 2006–2010.
Use the headings above to explore the stratigraphy and finds from five years of excavation at the site, to view the data, or to learn more about the project itself
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
Solid-Supported Benzotriazoles: Synthetic Auxiliaries and Traceless Linkers for the Combinatorial Synthesis of Amine Libraries
No full textThis paper describes the successful transfer of benzotriazole-based chemistry on solid support. The strategy followed to anchor this peculiar heterocycle on solid phase and the full analytical characterization of the various supported benzotriazoles are herein described. The chemistry assessment process on solid phase, the preparation of discrete libraries by parallel synthesis, the semiautomated purification procedures, and the complete analytical characterization of the library components are also presented and 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
