Age constraints and denudation rate of a multistage fault line scarp: an example from Southern Italy

The morphological evolution of a carbonate fault line scarp from southern Italy, generated by transpressional faulting and evolved by slope replacement, has been reconstructed. ¹⁴C dating of faulted slope deposits (ages included between 18 ka and ～8 ka BP) have been performed to constrain the Late Pleistocene — Holocene evolution of that scarp. Long-to short-term denudation rates have been also evaluated for the understanding of the mountain front origin. The slope shows well-defined triangular facets combined with the presence of N-S-striking mountainward-dipping fault planes. The envelope of the slope foot appears slightly curved in a planimetric view and shows an E-W-trending offset in its southern part, making such a feature quite different from the recurrent rectilinear fault scarps, often related to normal faulting. Morphostructural analysis showed that: i) the oldest displacement was generated by a fault with a reverse component of movement; ii) the slope represents an inherited feature, only recently exhumed, and developed starting from a high-angle curved surface; iii) the upper Pleistocene — Holocene extensional faulting has only affected the slope foot and associated waste deposits, causing a series of collateral morphological effects, as fluvial cut of preexisting valleys and the genesis of conspicuous mass movements.     

SPATIAL HETEROGENEITY AND THE WAGE CURVE REVISITED*

ABSTRACT Most “wage curve” studies ignore the geography of local labor markets. However, when a local labor market is in close proximity of other labor markets, a local shock that increases unemployment may not lead to lower pay rates if employers fear outward migration of their workers. Hence, the unemployment elasticity of pay will be greater, the more isolated the local labor market is. Wages are also expected to be higher in regions that interact strongly with other regions. These hypotheses are confirmed by means of an estimation of wage curves with data for 327 regions of western Germany over the period 1990–1997.     

Remote sensing techniques for reconstructing a vast Neolithic settlement in Southern Italy

The combined application of remote sensing techniques is often the most effective way for deepening the knowledge on very large archaeological sites (several hectares). In particular, geophysics and aerial photography could yield very detailed information on buried structures not only outlining their location but also, in many cases, defining their planimetry. Moreover, the accurate geocoding of different data sets and the use of GIS for their integration allow to extract the most comprehensive information from a combined study.     

Multitemporal analysis for preservation of obsidian sources from Melka Kunture (Ethiopia): integration of fieldwork activities,digital aerial photogrammetry and multispectral stereo-IKONOS II analysis

An integrated analysis of recent satellite imageries and dated aerial photos demonstrated to be a good investigation tool (Gallo et al., 2009) for the identification of new sites and for the assessment of landscape changes of wide archaeological areas in Ethiopia.     

Behind the scenes of public funding for performing arts in Italy: hidden phenomena beyond the rhetoric of legislation

This paper focuses on how Italian performing arts organizations were funded between 2003 and 2005. How does policy regulate the financing system for performing arts? What are the underlying logics that govern financing choices? In this paper the authors move beyond the simple examination of formal policies by analysing the funding data and organizational routines of the ministerial offices responsible for the allocation of grants. The authors implemented a multi‐method research methodology consisting of document analysis, in‐depth interviews, and quantitative analysis of funding data. The main findings can be summarized as follows. First, funds are continuously allocated to the same group of organizations. Second, although rigid, the system is imbued by a ‘rhetoric of the project’. Third, the system does not reward innovation. In conclusion, only by studying how the law is actually implemented can one capture the choices that underlie financing actions, and thus unravel unanticipated outcomes and inconsistencies between rhetoric and conduct.     

Late Palaeozoic South American pectinids revised: biostratigraphical and palaeogeographical implications

Neves, J.P., Anelli, L.E., Pagani, M.A. & Simões, M.G., 2014. Late Palaeozoic South American pectinids revised: biostratigraphical and palaeogeographical implications. Alcheringa 38 ISSN 0311-5518.

A revision of the late Palaeozoic South American pectinid Heteropecten multiscalptus (Thomas) and the establishment of Heteropecten paranaensis sp. nov. have important implications for the relationship between faunal realms within South America. Late Palaeozoic bivalve faunas occur in three distinct realms in South America: a Central Gondwanic Realm with endemic taxa showing affinities to Australia, New Zealand, South Africa and Namibia, a cold Perigondwanic Realm, and a warm Extragondwanic Realm with tethyan-like affinities similar to faunas of the American Midcontinent. In South America, faunas east of the southern Andes belong to the first two realms and previous interpretations of bivalve faunas suggested biocorrelations with those of the Extragondwanic Realm because they shared the taxon Heteropecten multiscalptus (Thomas). A revision of the Peruvian and Brazilian material does not confirm this. Instead, a re-analysis suggests that two species are present, rather than one: Heteropecten multiscalptus in the Cerro Prieto Formation, Amotape Mountains (Peru; Extragondwanic Realm), and Heteropecten paranaensis sp. nov. in the upper part of the Itararé Group, Paraná Basin (Brazil; Central Gondwanic Realm). Thus, the correlation between the late Palaeozoic faunas of the Central Gondwanic and Extragondwanic Realms in South America can no longer be supported. Heteropecten paranaensis sp. nov. lived in a siliciclastic-dominated, cold, epeiric sea of Brazil and Argentina, and is morphologically similar to some Australian species, whereas the Peruvian H. multiscalptus thrived in the warm seas of the Extragondwanic Realm.

Traditions of learning around the English Battle of the Books

This article calls for a reassessment of the Battle of the Books by arguing that the dispute did not simply oppose imitators of the ancients and supporters of modern critical scholarship, but that many scholars and critics were also attempting to support the authority of the ancients through their philological methods. A deep undercurrent of concern about the methods of philology can be traced in the development of biblical and patristic scholarship in the late seventeenth century. The article further emphasizes how the satirists (Swift especially) were aware of this strand of criticism, and yet how they hid their debt to it in order to portray textual criticism as a whole as a pedantic exercise. The Battle of the Books should therefore not be seen as a straightforward opposition between “supporters of the ancients” and “supporters of the moderns,” but as contention between doctrine and reason.     

The Early Middle Pleistocene Site of Gombore II (Melka Kunture,Upper Awash,Ethiopia) and the Issue of Acheulean Bifacial Shaping Strategies

The Gombore II site dates to circa the Brunhes Matuyama Reversal and is one of the Acheulean localities of the Melka Kunture (Upper Awash, Ethiopia) archaeological complex, known since the 1970s. In 2001, this locality was selected as the site for an Open Air Museum and thus excavated. The excavation area has yielded an abundant Acheulean lithic assemblage manufactured on volcanic raw materials in close association with numerous paleontological remains. A technological analysis was carried out on a fraction of the bifacial tools (bifaces and cleavers) which could be temporarily removed from the displayed surface in the museum. This set of artefacts reveals new data about the bifacial shaping strategies adopted at the beginning of the Middle Pleistocene in Ethiopia. The use of obsidian and the systematic manufacturing of twisted bifaces are original features of the assemblage. These data are discussed in the framework of penecontemporaneous East African sites.     

Upper Palaeolithic hunter-gatherer subsistence in Mediterranean coastal environments: an isotopic study of the diets of the earliest directly-dated humans from Sicily

The subsistence of hunter-gatherers in the Mediterranean Basin has been the object of few studies, which have not fully clarified the role of aquatic resources in their diets. Here we present the results of AMS radiocarbon dating and of isotope analyses on the earliest directly-dated human remains from Sicily, the largest island in the Mediterranean Sea. The radiocarbon determinations show that the Upper Palaeolithic (Epigravettian) humans from Grotta di San Teodoro (15 232–14 126 cal. BP) and Grotta Addaura Caprara (16 060–15 007 cal. BP) date to the Late-glacial and were possibly contemporary. The diets of these individuals were dominated by the protein of large terrestrial mammalian herbivores, such as red deer (Cervus elaphus). There is no evidence for the consumption of marine resources, which is probably the result not only of the oligotrophic nature of the Mediterranean, but also perhaps of the lack of adequate technology for exploiting intensively the resources from this sea. In spite of being contemporaneous and of the cultural and technological affinities present between the San Teodoro and Addaura humans, the carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope composition of their bone collagen suggests that significant differences were present in their diets. In particular, the hunter-gatherers from Grotta di San Teodoro, in NE Sicily where coastal plains are backed by high mountain chains (Monti Nebrodi), probably had easy access to resources such as anadromous brown trout (Salmo trutta), which might not have been similarly available in the NW of the island, where reliefs are noticeably lower and watercourses fewer and farther between. This study shows that the high biodiversity of this region, which results from the complex topography of Mediterranean landscapes, was probably exploited opportunistically by Late-glacial foragers. Our data also suggest that intensification and diversification of food acquisition in Sicily did not start in the closing stages of the late Pleistocene, as in other Mediterranean regions, probably because the island had only been (re-)colonized by humans around the Last Glacial Maximum.     

Does geographical location matter for ethnic wage gaps?

This paper analyzes ethnic wage gaps in Great Britain by comparing minorities to majority workers in the same local labor market and focuses on the variation of wage gaps across areas. As wage gaps vary across areas, using one single national measure may be misleading. Higher wage gaps across groups are associated with higher occupational segregation and ethnic diversity, while higher wage gaps within groups are associated with higher regional specialization and proportion of co-ethnics. Policies could help by improving job location and selection into occupations across groups.
