No full textGeophysical Surveys for Archaeology and Cultural Heritage Preservation
No full textThe knowledge that archaeological prospection is shaped by modern attitudes and procedures is important to the future of archaeology. Although geophysical studies have been applied to archaeological and historical sites over time with intermittent success, it is possible to derive great effects when used appropriately. It is most significant when applied in a well-integrated research design where interpretations are established and explored. The representation of survey data involves the knowledge of both archaeological evidence and the way it is stated in geophysical terms. Proper instrumentation, study design, and information processing are important for success, and these must be adapted according to the specific geology and archaeological evidence of each survey location. In this context, the regulation of information quality and spatial quality are important. This Special Issue of the Heritage journal expects to accumulate unique research articles on geophysical surveys for archaeology and cultural heritage preservation
Tracce del paesaggio antico nel Suburbio. I laterizi bollati nella raccolta Maruffi (collana editoriale Roma TrE-Press "Villa Maruffi. Materiali e Studi", n. 3)
No full textIl terzo volume dedicato ai materiali e agli studi in corso su Villa Maruffi, mette in evidenza l’interesse per la storia della cultura che scaturisce da questa struttura e dal territorio in cui è compresa, attraverso la raccolta di bolli impressi su laterizi antichi. Dalla contestualizzazione e dall’analisi di questi elementi emerge la testimonianza materiale della fitta trama di ville che caratterizza il suburbio di Roma fin dall’antichità, si seguono le fasi di più intensa edificazione e di declino, ma si possono ricostruire anche altre storie. Quella delle famiglie che ci hanno lasciato il loro marchio di fabbrica, oppure quella dei proprietari che hanno abitato nel tempo le stesse strutture, fino alla fase moderna di scoperta e di ‘estrazione’ dei materiali antichi dai terreni. Storie di persone, di attività, di luoghi, che si rivelano a chi ha la curiosità di guardare con interesse profondo anche le tracce meno appariscenti del nostro passato.
The third volume dedicated to materials and ongoing studies on Villa Maruffi, highlights the interest in the history of culture that flows from this structure and from the territory in which is, through the collection of stamps imprinted on bricks. From the contextualization and the analysis of those elements emerges the witness of the dense network of villas that characterise the suburbs of Rome since antiquity, you follow the most intense phases of construction and decline, but you can reconstruct even more stories. Stories of the families that left their trademark, or of the owners who have inhabited the same structures, until the modern phase of discovery and ' extraction ' of ancient materials from the suburbium of Rome. Stories of people, activities, places, which are revealed to those who have the curiosity to look with deep interest even less obvious traces of our past
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
