Long-distance provenance for obsidian artifacts of Mesoamerica Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park (Honduras)

Los Naranjos is one of the most important pre-Columbian human settlements of Honduras related to the south-easternmost border of the Mayan civilization. Although the archaeological site mostly spans from 850 BC to 1250 AD, the present obsidian study was only focused on the Preclassic and Early Classic periods (Jaral, 800–400 BC and Edén, 400 BC–550 AD) where undamaged blades and/or retouched obsidian flakes are rare. In this way, the INAA analyses of 17 obsidian samples, compared with major-trace elements data of Honduran and Guatemalan obsidian sources, are mostly representative of waste flakes. Lithic artifacts of Los Naranjos such as sandstones, basalts, and quartzites come from local geological outcrops; whereas, obsidian provenance has to be searched from sources which are located within a radius up to 300 km far away. San Luis, La Esperanza, and Güinope obsidian sources are located in Honduras while the three most exploited Highland Guatemalan obsidian outcrops, which have been dominating long-distance trade in the Maya area mostly for the Classic-Postclassic periods, are San Martin de Jilotepeque, El Chayal, and Ixtepeque. An Ixtepeque provenance, for all the investigated obsidian samples of Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park, was established, thus emphasizing a long-distance source (180 km). This also confirms that Ixtepeque represents the most important provenance of the obsidian artifacts found in archaeological sites of Western and Central-Western Honduras. The possible role played by some of the most important rivers of Guatemala and Honduras as waterway networks of transport was finally pointed out. New INAA chemical data from the Honduran obsidian source of La Esperanza (“Los Hoyos”, 4 samples) are also reported in this paper.     

Digital Photogrammetry for Documentation of Maritime Heritage

Documentation of maritime heritage is essential for its protection, and for reference in restoration and renovation processes. These functions become problematic in the case of historical ships and boats that lack lines drawings. The purpose of this paper is to describe a procedure for creation of lines drawings based on the shape analysis of surviving historical boats or their small-scale models with the help of reverse engineering (RE) techniques. The paper describes how digital photogrammetry and the iterative method were used to analyze the shape of three historical boats: Tomahawk, Refola and Nada. The application of the proposed procedure produced the lines drawings of the boats as its result. The accuracy of the 3D CAD model obtained with the photogrammetric technique was verified by comparing it against a more accurate 3D model produced with the help of a RE laser scanner. The examination of the resulting lines drawings proves that the digital photogrammetry process and the proposed iterative method are adequate tools for developing lines plans of boat models. The research offers the methodological basis for the creation of an archive of lines drawings of historical boats. Such an archive would provide reference for philologically correct restorations, and permit definition and classification of distinctive elements of various types of historical boats, particularly those produced in the Campania Region.     

First Trials to Set Up a Microwave Reflectometric Tool for the Survey of Historic Timber Structures

Timber structures can be degraded during their life both by structural problems and by biological degradation factors like fungi and insects. The occurrence of those biodegradation agents could lead to a loss of their structural integrity, in the absence of appropriate maintenance. An early assessment of the decay is even more important when the wooden structures are part of historical buildings, in the interest of conservation of cultural heritage.

This article presents an application of microwave reflectometry for the in situ evaluation of timber structures. The measurement system allows detecting anomalies inside the material in a non-destructive and non-invasive manner.

The reflection coefficient is measured by means of a vector network analyzer (VNA) using a double-ridge antenna which transmits the continuous-wave (CW) microwave signal and receives the signal reflected by the material under investigation.

Measurements on laboratory models demonstrated the feasibility of the method. Results obtained on timber beam sections, compared with the findings of traditional investigation methodologies, demonstrate the potentiality of microwave reflectometry, suggesting its possible usefulness during the diagnostic phase as a non-invasive tool for preliminary screening.     

Infrastructure and Growth in a Spatial Framework: Evidence from the EU regions

This paper examines the return to infrastructure in the European Union regions in a spatial framework. It innovates on the earlier literature on infrastructure and growth by a combination of regional focus, disaggregation of infrastructure types and consideration of spatial dependence. Different types of infrastructure capital are considered as determinants of economic performance at the Nomenclature des Unités Territoriales Statistiques level. To account for growth spillovers among regions, a spatial Durbin model is estimated. The results confirm the important role of infrastructure and identify the highest rates of return as associated with telecommunication, quality and accessibility of transportation networks, with a positive impact of roads and railways.     

THE EMERGENCE OF STRATIGRAPHIC ARCHAEOLOGY IN MEDITERRANEAN EUROPE

In Italian classical archaeology, the definitive adoption of the stratigraphic excavation method occurred later than in other European countries. This methodological shift took place in Italy in the 1970s. We aim to scrutinize some points of the established historiographical reconstruction. We focus on three scholars regarded as “key figures” in the birth of Italian stratigraphic archaeology, yet all of the first half of the twentieth century, Giacomo Boni, Nino Lamboglia, and Luigi Bernabò Brea. We examine the origin of their stratigraphic approach and thus their relationship with prehistoric research. This is also an opportunity to reflect upon the conceptual and methodological transfer from one type of archaeology to another. In general, through comparison of these scholars, we aim to highlight some key factors in the establishment of a stratigraphic method in the history of archaeology.     

A Multi-scalar Approach to Place Branding: The 150th Anniversary of Italian Unification in Turin

This study draws from an interpretation of scale as a social construct to elaborate a multi-scalar approach to place branding that represents a growing set of theories and managerial practices aimed at leveraging the reputational capital of places. The article unveils that far from consisting of clear-cut processes which occur within a pre-given and fixed set of scalar boundaries, city, regional, country and supra-national brandings actually converge in a complex mechanism of intertwined practices and discourses. By grounding its theoretical investigation in a case study about the celebration of the 150th anniversary of Italian unification, this paper furthers the understanding of place branding from a multi-level perspective, addressing the tendency of previous studies to treat scale as a fixed hierarchy of nested levels. The findings show that scalar boundaries remain significant for the purpose of coordination and identification among the institutional actors involved. And yet, the investigation highlights that scalar boundaries do not constitute a structure of ontologically given contexts, but rather are the outcome of an ongoing dialectic process among place stakeholders through which scalar relations are constantly reproduced and nurtured during the staging of the place branding project.     

Direct evidence of the use of beehive products in pre-Roman Sardinia

Written sources and iconographic evidence suggest that honey and beehive products, used in culinary, medicinal, and technological functions since pre-Neolithic times, were likely known and used in Phoenician and Punic Sardinia. The role of these resources is nonetheless poorly understood because no direct evidence survives on a macroscopic level. Significant advances in the knowledge about beeswax and beehive products processing in the past have been offered in recent decades by organic residue analyses (ORA), an approach that enables the characterisation of surviving chemical compounds or suites of compounds that provide information relating to human activity in the past. The relatively recalcitrant nature of lipid compounds comprising beeswax means that this commodity is among the products that can be unambiguously identified through ORA. Here we present and discuss the results of analyses undertaken on 368 pottery sherds from Phoenician and Punic Sardinia (eighth to third century BCE). These analyses offer direct evidence for the presence of beehive products on the island, suggesting the use of honey for culinary purposes in pots, and possibly connecting one specific vessel category with beeswax decanting during beekeeping and honey production processes. Our results also now clearly illustrate the widespread use of beehive products in pre-Roman Sardinia.     

The Production of Commons and the “Explosion” of the Middle Class

Abstract: This paper builds on the author's previous theoretical work on the role of processes such as enclosures, market discipline and governance. It discusses the middle class in terms of a stratified field of subjectivity within the planetary wage hierarchy produced by these processes. It discusses the thesis that the middle class, qua middle class, will never be able to contribute to bring about a fundamental change in the capitalist system of livelihood reproduction. The production in common centered on middle class values—however historically and culturally specific they are—is always production in common within the system. Our common action as middle class action, whether as consumers, workers, or citizens, reproduces the system of value and value hierarchy that is the benchmark, the referent point for our cooperation. The paper then discusses some of the implications of the conundrum faced by those who seek alternatives: there will be no “beginning of history” without the middle class, nor there will be one with the middle class.     

The Effect of Business Support on Employment in Manufacturing: Evidence from the European Union Structural Funds in Germany,Italy and Spain

This study investigates employment growth in the business activities supported by the European Cohesion Policy. We examine cross-industry, cross-regional variations in a sample of fourteen manufacturing industries and seventy European regions (in Germany, Italy and Spain) and take advantage of detailed European Union Structural Funds data at the regional level for the period 2000–2006. We show that business support is positively associated with higher employment growth in industries that are initially smaller and in those with higher growth opportunities. The results suggest that direct support to businesses by the European Cohesion Policy contributes to the growth process of employment in different industries. Because previous estimated effects at the aggregate level may in fact conceal large differences across industries, we conclude that our empirical analysis contributes to the understanding of how Structural Funds can affect industrial and regional development as well as adjustment paths.
