Minero-petrographic characterization of fine ware from Cales (South Italy)

79 samples of black glazed pottery, Terra sigillata, fine common ware, and production indicators were recovered in the archaeological site of Cales and investigated via a multi-analytical program (polarized light microscopy, thermal analyses, XRPD, XRF, FESEM, FESEM-EDS). Among the materials, finds of important production indicators, represented by welded pieces of black glazed pottery and spacers, attest a local production. Polarized light microscopy shows that the inclusions consist of feldspar, quartz, mica, calcite, and lithic fragments of both volcanic and sedimentary nature. Additional information about the mineralogical assemblage comes from the XRPD that revealed the presence of neoformed Ca-silicates, indicating equivalent firing temperatures ranging from 750 to 1050°C. All the samples show a Ca-rich character and an extreme compositional homogeneity, including the production indicators. The comparison with some Ca-rich Campanian clay raw materials shows a greater affinity with the Mio-Pliocene marine clay sediments of the Apennine sector, which include local clays. This allowed us to formulate the first hypotheses about clay sources used to produce fine pottery during the third century BCE to the early imperial period in Cales.     

Urban Planning System in Contemporary Spain

This work analyses the main Spanish legislative and urban planning instruments, highlighting some of the most important structural problems of the current Spanish urban realities. The survey on legislation runs from the first Land Use Act of 1956 to the decentralization of the administration and the culmination of the transfer processes to the respective Spanish regions. Later, we study the complete well-structured hierarchy of urban planning instruments in use at present. Finally, we analyse how these and other factors have an influence on the capacity to control housing prices and on a lack of sustainability characterized by the excessive urbanizing use of the land.     

Taxonomic characterisation of fresh Dipterocarpaceae resins by gas chromatography–mass spectrometry (GC–MS): providing clues for identification of unknown archaeological resins

Plant and particularly non-wood forest products have played an important role in the evolution of human cultures all over the world, as source of food but also of raw substances fulfilling material, spiritual, and medicinal requirements. Plant exudates and particularly dammar resins (Dipterocarpaceae family) were widely used in the past in Asia notably as waterproofing and caulking materials. This study focuses on the GC–MS chemical characterisation of freshly collected dammars and establishes new molecular parameters enabling discrimination between dammars and other types of plant resin, whatever their botanical origin. Such analyses provide clues for a precise identification (taxonomy, occurrence of other material in addition to the resin, alteration state) of unknown resinous material discovered in archaeological contexts. The value of our approach is illustrated by the taxonomic characterisation of two samples collected in jars from the Brunei wreck and a Chinese junk lost more than 40 km off the Sultanate of Brunei during the end of the fifteenth century or the early beginning of the sixteenth century.     

Hunter–gatherer responses to environmental change during the Pleistocene–Holocene transition in the southern North Sea basin: Final Palaeolithic–Final Mesolithic land use in northwest Belgium

Situated along the southern fringe of the North Sea basin, northwest Belgium holds great potential for understanding hunter–gatherer responses to environmental change at the Pleistocene–Holocene transition. Recent intensive fieldwork has yielded valuable data on the palaeoenvironment, chronology, and hunter–gatherer mobility and land use in this region. At the Late Glacial/Early Holocene transition this region was comprised of a landscape of coversand ridges and lakes that flanked the northern part of the Scheldt river basin. This landscape was highly productive for hunter–gatherer populations. As the landscape developed in response to the increasing water table caused by the inundation of the North Sea populations responded by changing their forms of mobility and land use. These changes are indicated by the reduction in the number and density of sites, as well as their geographical settings, from the Late Glacial (Federmesser) and Early Mesolithic to the Middle-Final Mesolithic. Late Glacial/Early Mesolithic sites indicate much higher mobility comprised of rapid displacements of camps and re-occupation of the same coversand ridges over long time-spans. Middle/Late Mesolithic sites indicate a reduction in mobility, increasing focus on prolonged riverside settlement, and a more rigid organization of residential sites.     

‘YOUTH RIOTS’ AND THE CONCEPT OF CONTENTIOUS POLITICS IN HISTORICAL RESEARCH

This article analyses European ‘youth riots’ as a social phenomenon after World War II. It also uses a specific riot – the 1948 Stockholm Easter Riots – in order to discuss the limits and potential of some theoretical assumptions underlying the field of historical contentious politics studies, primarily ‘contentious politics’ and ‘claims’. Using police reports and newspapers, the article shows that the riots were part of a European repertoire of post-war ‘youth riots’, but that they also bear similarities to an older popular repertoire of contention in Sweden. However, the riots do not really fit into the concept of ‘contentious politics’, as this concept is built on ‘claim-making’ as a key aspect and the participants did not make explicit claims. This leads to the conclusion that other theoretical tools, inspired by the concept of ‘moral economy’, are better suited for understanding the motivations of the rioters, whose actions are interpreted as a way of defending a perceived moral right of access to the urban public space.     

The influence of territory on innovation network design in mountain tourism resorts

As there is little research on the link between territories and interorganisational networks, this paper examines how the nature of a territory influences the characteristics of innovation networks. It compares the innovation network forms of two types of territories (high-altitude and medium-altitude mountain resorts) regarding four characteristics of networks widely debated in the literature: the nature of the relationships between members, the mode of regulation used, the architecture, and the geographical proximity of members. This research makes a significant contribution to both the spatial development and innovation management literature: indeed, our results show that according to the nature of the territory, innovation networks differ in terms of partners, geographical proximity, and regulation mode. However, the nature of the territory does not seem to influence the architecture of the innovation network since those networks need a hub organization that orchestrates the partners’ actions. These results, by providing a better understanding of the characteristics of innovation networks, help tourist territories to better attract customers.     

CROSS‐CHANNEL CONNECTIVITY: WEALDEN WHETSTONE IMPORTS FROM ROMAN BRITAIN TO THE CONTINENT

The purpose of this paper is to demonstrate cross‐Channel exchange of calcareous sandstone‐type whetstones derived from the Weald (Sussex, UK) in the Roman period. The presence of this particular type of whetstone at several Roman sites on the Continent – more specifically, in Belgium, France and the Netherlands – is reported for the first time. The morphology, geological provenance, petrographic characteristics and distribution patterns are discussed, based on a comparative analysis with archaeological and geological reference material. The geological analysis identifies a common geological source for the Continental finds: the very fine‐grained, thin‐bedded, flagstone‐like calcareous sandstone beds of the Lower Cretaceous Wealden Clay Formation. These sandstones were, most probably, extracted in the north‐western part of the Weald area. The distribution pattern of the archaeological material implies the importance of personal mobility, with potential military affinities.     

Identifying a technological style in the making of lime plasters at Teopancazco (Teotihuacan,México)

The aim of this article is to focus on the technology of archeological plasters at Teotihuacan (Central Mexico), from the Classic Period (200–650 A.D.), focusing in the study of Teopancazco, a neighborhood center in the city. Petrographic and chemical analyses by OM, SEM-EDS, and LA-ICP-MS were conducted to characterize samples from different constructive phases and sectors of the neighborhood center, to determine the provenance of the raw materials employed in the manufacturing (e.g., volcanic glass shards) and to assess whether a shift occurred in the manufacturing of plasters and in the procurement strategies of raw materials during the different phases. The results of the analyses show that almost no changes occurred in the making of the plaster during more than four centuries and allow us to consider the presence of a technological style in their manufacture, which is characterized by the making of plaster by mixing lime with volcanic glass shards, which in the case of Teopancazco were derived from the Altotonga (Veracruz) magmatic system. The data at our disposal suggest that this style was developed in Teopancazco and later introduced throughout the city of Teotihuacan in the Early Xolalpan phase (A.D. 350), although we still do not know whether the provenance of the raw materials is the same. The wide distribution of this technological tradition could be due to the technological properties of the materials and/or the influence of the intermediate elite who ruled over Teopancazco. The paper confirms that the study of material culture and technology sheds light on broader cultural aspects of ancient societies.
