The Campanian agrarian systems of the late Copper-Early Bronze Age (ca. 4550-3850 cal BP). A long-lasting agrarian management tradition before the Pomici di Avellino eruption
No full textIn the Piana Campana (Southern Italy), the repeated and sometimes devastating volcanic activities of the Somma-Vesuvius and Campi Flegrei, spread over a wide area and over centuries, led archaeologists to the recovery of detailed data about the past environment and human occupation during the Late Holocene. Settlements, burials, landscape and agrarian infrastructures (fields, tracks, wells, etc.) show an intense and continuous human presence since at least late Neolithic times (ca. 6.2 ka cal BP) also confirmed in the pollen diagrams. The investigations conducted at Gricignano d’Aversa/US Navy support site by the Soprintendenze of the Italian Ministry of Culture from 1995 to 2005 allow us to analyze positive and negative agrarian traces, mainly consisting in shallow gullies and banks, plough furrows, plough-marks, and cart-tracks and cart-ruts bottoms. A discussion of the methodology to be applied to agrarian traces is developed. The resulting pattern shows the regularity of the Copper and Early Bronze Age field systems during the time span between ca. 4550 and 3850 cal BP (resp. Agnano Monte Spina and Avellino eruptions). The Phlegraean eruptions occurring between these two major events, probably originating from Astroni, did not have a disrupting effect, anyway probably forcing a re-arrangement of the field system, and possibly also of settlements. The preserved archaeological deposits of the Piana Campana are starting to reveal a still underdeveloped potential in terms of ancient landscape reconstruction
La ceramica dal casale in località Céscole a Itri (LT): nuove fonti archeologiche per lo studio della società bassomedievale tra la contea di Fondi ed il porto di Gaeta
No full textL'area del golfo di Gaeta sino ad ora non è stata interessata da sistematiche ricerche di archeologia medievale. In particolare, ben poco si conosce della cultura materiale bassomedievale, soprattutto della ceramica di uso quotidiano. In questo contributo si vuole fornire una descrizione dei materiali rinvenuti all’interno e nell’area circostante il casale in località Céscole in Itri (Lazio, Italia), consistenti principalmente in anfore di varia dimensione di riutilizzo e in altre forme di ceramica acroma e dipinta. Nella prima parte sono raccolte informazioni sul contesto storico regionale del XIV secolo ed alcune brevi note sulla topografia dell’area del casale. La seconda parte fornisce uno studio dettagliato dei materiali condotto col fine di interpretare al meglio quelle che sembrerebbero essere attestazioni di particolare interesse per le produzioni tardo medievali dell’area costiera campano-laziale, nonché i primi di questo tipo documentati nell’area di Itri. Il casale con torre in località Céscole costituisce con i suoi materiali un nuovo contesto che, a seguito di ulteriori e più approfondite indagini, potrà in futuro fornire dati di natura archeologica utili alla ricostruzione del paesaggio rurale orbitante intorno al Castrum Ytri tra XIV e XV secolo.To date, the area of the gulf of Gaeta has never been involved in systematic Medieval Archaeology research. Very little is known, for instance, about the late Medieval material culture of this region, especially concerning pottery for everyday use. The aim of this paper is to provide a first description of the pottery found in and around the casale located at le Céscole in Itri (Lazio, Italy). This material consists mostly of amphorae and other painted wares. In the first part of the paper, we provide information about the regional historical context for the XIV century. The second part includes a detailed study of the pottery found in the casale and aims to give a first interpretation of it. The pottery could be an important attestation of the late Medieval production of the coast between Lazio and Campania and the first of this kind ever to be reported from Itri. The casale at le Céscole, together with its pottery, represents a new context from which, through further investigations, we can hope to extrapolate more archaeological data in the near future. These data will surely aid us in reconstructing the rural landscape orbiting around the Castrum Ytri between the XIV and the XV century
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
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
