Looking for the invisible: landscape change and ceramic manufacture during the Final Neolithic-Early Bronze Age at Phaistos (Crete, Greece)
No full textThe present landscape of the Mesara Plain, an intermountain basin located in Southern Crete, results from millennia of geological transformation. Human presence in the area had a strong impact on landscape change since the Final Neolithic (second half of the 4th millennium BC), when the first signs of land erosion and deforestation appeared. This phase has been considered in Crete as “transitional” due to emergence of new settlement patterns and material culture. The main site on the Plain is Phaistos, which is located on a hilltop near the Yerapotamos River. The site offers great potential for the examination of the Final Neolithic-Early Bronze Age transition in Crete, on account of the landscape and changes in the human occupation and manufacturing activity. Pottery manufacture of these transitional phases has been examined in detail, revealing a complex picture of continuity and change in raw material use. Similarly, our understanding of the landscape surrounding the site has been transformed with the discovery of the formation of a lake to the South of the hill site from the mid-3rd millennium. This paper presents collabo- rative research on landscape change and its influence on raw material availability for pottery manufacture in the area
Holocene palaeogeographical and palaeoenvironmental reconstructions of the Messara alluvial-coastal plain (Southern Crete, Greece): the Phaistos project and the Dikida program, in Abstract Volume , Pisa, 15-17 February 2012, 60
No full textThe Yeropotamos alluvial-coastal plain (Southern Crete, Greece) lies on the E-W oriented graben of the Messara, which is mainly constituted by Late Pleistocene and Holocene alluvial, fluvial-marshy, slope and coastal deposits. All the Messara basin is characterized by important seismicity, which caused damages and destructions on several archaeological settlements of Minoan, Hellenistic and Roman age. Within the PHAISTOS project and the DIKIDA program, in order to reconstruct the
Holocene paleogeographical and paleoenvironmental evolution, in relation to the settling history of the Messara, new archeo-stratigraphical and geomorphological studies were carried out. The
geomorphological approach, based on 1:5.000 and 1:10.000 cartography, photo-aerial remote sensing and field-survey allowed to identify the main landscape units and helped to better understand the ancient and the present-day morphodynamics, mainly induced by climatic changes, tectonic, and man. This approach distinguished the areas under aggradation and erosion processes during the Holocene times, in order to provide useful data about presence/absence of archaeological remains and traces. The archaeo-stratigraphical approach was based on field-survey and new drilled cores, supported by facies analyses and age-constrained by 14C and archeological datings.
Preliminary data from the cores drilled in the Grya Saita area, a large fluvial-marshy depression located near the Festos archaeological site, identified the main palaeoenvironmental changes occurred during the Holocene. For the Holocene coastal evolution the available data allow to suppose that the Minoan shoreline was very close to the Festos and Agia Triada settlements, forming a ria into the Yeropotamos alluvial-coastal plain. Then the shoreline rapidly shifted westwards, forming prograding barrier-lagoon systems, that existed until very recent times. The main causes of the shoreline progradation can be related to the decrease of the sea level rise rate together with the increase of the sediment load by the rivers, connected to the more intense land use
by Minoans, Greeks and Romans, and to the vertical land movements connected to the seismicity
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
