Il mare dentro l'isola: un approccio territoriale allo studio delle risorse legate al mare nel Neolitico e nell'età del Bronzo in Sicilia
No full textPrehistoric settlement strategies reflect a palimpsest of environmental, economic, and cultural variables. On islands, these strategies are influenced in a peculiar way by the sea, its presence either facilitating contact or posing an obstacle for communities, who choose to move towards the coast or away from it leaning towards the interior - its influence always significant but variable over time. This paper reviews and discusses the different settlement patterns in Sicily during the Neolithic and the Bronze Age, as known from the existing literature, through a regional-scale survey in a Geographic Information System (GIS) environment, comparing the settlement data with the distribution and the exploitation of sea-related resources. Our investigation takes advantage of three-dimensional analysis tools that are widely used to carry out spatial analyses, applied on a digital model of the terrain with a ground resolution of ten meters. Specifically, the work focuses on visibility analysis (viewshed analysis) and accessibility across the landscape (Least Cost Analysis) of the most representative sites of the different phases of Sicilian prehistory. The aim of the analysis is to verify possible connections between the hinterland and the coast, taking into account their different geomorphological characteristics. Alongside the territorial analysis, we examine a series of variables directly or indirectly linked to the sea in the periods under consideration, specifically raw materials (obsidian), resources linked to the sea (marine molluscs, marine ichthyofauna), as well as distinctive ceramic productions from areas beyond the sea, such as Capo Graziano pottery from the Aeolian Islands and pottery from the Aegean region. Starting from this comparison, the paper discusses how and to what extent the presence of the sea permeated the existence of prehistoric communities in the Neolithic and in the Bronze Age, beyond the coastal area and towards the island’s interior

The Rural Settlement of Contrada Castro (Sicily) between Antiquity and the Early Middle Ages
No full textIn 2015, the University of Palermo, the Soprintendenza BB.CC.AA. of Palermo, and the private biofarm Bona Furtuna LLC formed a fruitful collaboration within the Harvesting Memories Project, which focuses on the study of long-term landscape transformations as a result of the diachronic interaction between socioeconomic human patterns and environmental and ecological trends. As part of a holistic vision of landscape conservation connected to 100 percent organic farming activities, a research program was developed that sought to understand the historical and ecological dynamics of a sector of the Sicani Mountains located in the southern part of the municipality of Corleone in the province of Palermo. The project uses an interdisciplinary approach that involves historical, archaeological, botanical, paleo-environmental studies and the use of GIS and remote sensing tools. The long occupation of this rural district has been documented by an archaeological survey that lead to the identification and mapping of different areas with human occupation from protohistory to the modern age. This survey identified a settlement with high archaeological potential located in the hilltop plateau of Contrada Castro where archaeological excavation campaigns have been carried out since 2017. The excavations have confirmed the long occupation of the hill that began with an inhabited area from the sixth to the fourth centuries BCE and a reoccupation during the Early Middle Ages, characterized by Contrada Castro (Sicily) between Antiquity and the Early Middle Ages 241 two macro phases between the late eighth–ninth and the tenth–eleventh centuries CE, the phase of the complex transition between the Byzantine and Islamic period
The human entry in Sicily: new archaeological and paleoenvironmental evidence from San Teodoro cave (Acquedolci, Messina)
Get PDFThe timing of the earliest peopling of Sicily and, to a wider level, of human mobility in the Mediterranean basin after the Last Glacial Maximum is enriched by the recent discovery of an archaeological record dated back to 16,5 ka cal BP from San Teodoro cave (Acquedolci, Messina). We present the results of a new archaeological campaign inside the grotto, where we were able to identify a layer related to the initial stage of human occupation. The excavation yielded lithic and faunal remains and the first systematic collection of wood charcoal for the archaeobotanical analysis. The new data offer a snapshot on the site and on the daily activities of the hunter-gatherers in their palaeoenvironmental context. The peri-coastal area surrounding San Teodoro appears to have played a role as a glacial refuge, allowing for the development and survival of temperate tree species. New evidence also gives an overview on the initial stages of the peopling of Sicily. The chronology of the layer is not only the oldest from the cave, but also from the region. The new radiocarbon dates, coupled with the chronological framework reconstructed so far, allows a parsimonious recognition of a westward movement of human populations (from the eastern Messina province to the Egadi, on the west). The time of the first spread of human groups on Sicily has to be considered as a consequence of the rapid demographic increase that has been registered in Southern Italy, since the early stages of the Late Epigravettian, and can be related to the amelioration of local environmental conditions in both areas
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
