    The aim of this paper is to spread some light on the socio-economics and environmental dynamics which took place between the Late Antiquity and the Early Middle Ages, and which played a role in the reshaping of the post-classical settlement pattern in the Salento region (Southern Apulia). The research programs carried out over the last two decades by the Laboratory for Medieval Archaeology of the University of Salento have led to the creation of a GIS database of settlements and other archaeological evidence dating to the Middle Ages. This huge archaeo-historical dataset is correlated with evidence from different disciplines (archaeobotanic, archaeozoology, geology, pedology, climatology and many others). The extensive survey of the region has been integrated by more in-depth “micro-regional intensive survey” projects aimed to seek an answer to specific research questions. During the late roman imperial period and until the first decades of the 6th century, the local settlement pattern was characterized by few major cities, a certain number of rural villages (vici) and a huge quantity of small sites, mostly recognized by pottery scatters individuated during fieldworks and usually interpreted as generic farmsteads. Quantitative analyses based on archaeological datasets clearly display that a substantial decrease in the number of settlements took part during the course of 6th century, when many roman towns and villages underwent abandonment or severe resize. The dissolution of the pre-existent settlement pattern can be read as an aspect of the collapse of the Roman Imperial and Late Antique economic system, also due to traumatic events such as the Greek-Gothic War, the Justinianic Plague and the Lombard conquest of Italy. Many of the imported artefacts, mainly African and Aegean transport amphorae and domestic fine wares, broadly diffused also in the smaller rural sites in the inland part of the region until the mid-6th century, suddenly disappear from later ceramic assemblages, with the only exception of those found in few privileged places such as Otranto. However, the general picture of the rural organisation during the transitional period between the end of the 6th and the mid-7th century is far for clear, due to the lack in our knowledge about local material culture. According to the evidence collected through different fieldworks, after the hiatus of the 6th-7th century, the region witnessed a sensible and diffuse growth in the number of rural settlements. Surveys conducted in the Alimini Lakes area, north of the port-town of Otranto, revealed a flourishing of medium and small Imperial and Late Antique settlements in a previously almost deserted landscape, reflecting a situation documented elsewhere in Salento (e.g. in the hinterland of Vaste). A general reassessment of the settlement pattern took place during the Early Byzantine period, with the abandonment of some of the afore mentioned sites and the appearance of a certain number of farms and villages in previously unoccupied locations. One of these sites, at Loc. Pagliarone, excavated in 2010, has revealed traces of occupation spanning from at least the 8th until the 13th century. Palynological analyses show a rapid growth of olive cultivation in the area, confirming the picture emerging from archaeological researches. A similar demographic trend is recorded in the strip comprised between the city of Lecce and the Adriatic port of San Cataldo, where 13 small farms or hamlets dating to the 7th-9th century have been recognized during field survey. Also along the west coast of the peninsula, in the territory of Nardò, archaeological fieldworks showed that many of the casalia mentioned in the late medieval documents were already in existence during the Early Middle Ages. In addition to the aforementioned fieldworks, some infrasite surveys and excavations have been conducted with the intent to enhance our knowledge about early medieval settlement dynamics and forms. The site excavated at Loc. Scorpo, near Supersano, is the best known local example of a Byzantine village. It consists of a group of sunken-featured structures, some of which have been interpreted as huts (grubenhauser), located in a marginal landscape, at the near edges of a forest and a marsh. The village lifetime spans from the second half of the 7th to the end of the 8th or the beginning of the 9th century, as proved by radio carbon and RHX dating. A short and sporadic reoccupation of the site is documented around the 10th-11th century. The early medieval village found at Scorpo was founded in a previously unoccupied area, and apparently the only roman imperial settlement in the vicinity (Loc. Falconiera) is about 1 km far. On the basis of excavations and infrasite surveys, at least three settlement models have been recognized, which summarize the archaeological records of the region: Byzantine rural settlements which developed in the same location or in proximity of pre-existent Roman sites and disappeared within the Early Middle Ages (e.g. the village found at Loc. S. Elia, Corigliano); Byzantine rural settlements which occupied the same location of pre-existent Roman sites and survived until the end of the Middle Ages (e.g. the multistratified site at Loc. Badia, Cutrofiano); early medieval foundations which survived at least until the end of the Middle Ages (e.g. the medieval village of S. Maria de la Vetrana). The domestic assemblages found at these early medieval sites show strong link with byzantine models until the second half of the 9th century, revealing the existence of a cultural koiné including the lower Adriatic territories. Long distance trades seem to involve only the major cities and the coastal towns, while pottery and globular amphorae of local production are predominant in the hinterland villages. The only imported artefacts found in the excavations at Scorpo and Apigliano are some rotary querns made from volcanic stone maybe from Etna and Melos and a few high valuable objects. According to the presented archaeological data, collected through excavations and fieldworks in various part of the Salento, the number of rural settlements seem to increase during the very first centuries of the Early Middle Ages, maybe already at the end of the 7th century. The archaeological evidence clearly testifies that in most of the cases we deal with small human foci, with a predominantly autarchic economy and sometimes inclined to the production of small surpluses. The growing number of villages and farms is not necessarily linked with a demographic boost, yet it could be the consequence of an extreme fragmentation of settlement dynamics during a period of economic reorganization. At the status of our knowledge is pretty hard trying to define some hierarchical structure. However, it seems possible to identify a complementary role played in the regional economy by village communities devoted to agricultural production and a few major élite centres of consumption and redistribution of goods. Anyway, this exasperated fragmentation of the human habitat could be one symptom of the expansion of cultivated areas, probably linked to the initiative of the Byzantine élites and/or authorities. A new reassessment in the local settlement pattern is documented in the Salento between the second half of the 9th and the beginning of the following century, when many small villages and farms were abandoned to the advantage of some privileged centres, in the context of a general reorganization of the land system in Terra d’Otranto

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Clinical Comparative Study for Validation of Digital Impression Reliability with the Gypsum Check: A Simple and Fast Way to Evaluate the Trueness and Accuracy of Implant-Supported Rehabilitation

    Despite many advantages, digital impressions, when compared to the conventional one, produce contrasting results and their complete substitution is still under debate. This comparative study aims to test a way to perform a clinical evaluation of digital impression Accuracy and Trueness with a gypsum check. After calculating the Trueness, Precision, and Accuracy of the digital impressions, a gypsum check was fabricated and screwed on implant abutments. The impression was not considered reliable if the gypsum check fractured during the insertion. The gypsum check test was correlated to a cut-off of 100 μm Trueness. Mean Trueness was 151.19 ± 37.23 μm of the first optical impression and 125.47 ± 41.90 μm of the second optical impression. The Precision mean was 39.76 ± 10.89 μm. The mean Accuracy percentage was 98.69 ± 0.29%. The gypsum checks fractured 10 times on 42 tests, and in any case, the Trueness value was above the 100 μm cut off, with a p = 0.001. A gypsum check screwed onto an implant abutment could be considered a way to perform clinical measurement of Trueness, allowing the clinician to understand if the Trueness value is higher or lower than 100 μm and reflecting the reliability of digital impressions
