Paleopathological and Molecular Study on Two Cases of Ancient Childhood Leprosy from the Roman and Byzantine Empires

This study is based on the paleaopathology of leprosy on human skeletal remains and the detection of ancient Mycobacterium leprae DNA. Two cases of childhood leprosy were recognized. The first case was in a Roman necropolis at Martellona (Rome, Central Italy), dated to the 2nd to 3rd centuries ce . The skeleton of a child aged 4–5 years, from tomb 162, is the youngest individual in Italy from this time period, with the clear rhino‐maxillary syndrome and other bony changes indicative of leprosy. The second case from a burial at Kovuklukaya, in the Sinop region of Northern Turkey, was from the 8th to the 10th centuries, during the Byzantine era. The endocranium of a 4–5‐month‐old infant with new bone formation—an indication of chronic inflammation—was positive for M. leprae DNA. Infant and childhood leprosy is uncommon today, and there is a scarcity of information in the osteoarchaeological literature of leprosy in the past, especially in children. The significance of these cases is that it adds to an understanding of the history of the disease in the former Roman Empire. It is hoped that over time sufficient data can be obtained to understand the epidemiological dynamics and clinical evolution of leprosy from the ancient period until today.

Technology,chronology and the role of crucible steel as inferred from iron objects of the ancient site at Junnar,India

Ordinary iron objects from an ancient habitation site at Junnar in India, dating to the 2nd BC to AD 2nd century, were examined for their microstructure, chemical composition and age. The objects were mostly made of high carbon steel with a homogeneous microstructure consisting of fine spherical particles of carbide in the ferrite background, free of non-metallic inclusions. Their carbon concentration ranged from 0.7% to over 1.6% with one exception at 0.2%. Some of them contained trace amounts of silicon, manganese and sulfur while one object retained cavities due to volume contraction during solidification reactions. These features indicate that the objects examined constitute an early example of Indian steel making in crucibles. Evidence was found that basic techniques needed for the success of crucible steel technology were mostly available at Junnar at the time. The radiocarbon measurement on carbon samples extracted from one of the iron objects placed its date between 176 BC and AD 20, in agreement with the radiocarbon dates of three charcoal samples from the same site. The forgoing results support that crucible steel was produced in India at a much earlier date than previously supposed, to serve as a material for specific needs arising in daily life.     

ENVIRONMENTAL AND EVOLUTIONARY ECONOMIC GEOGRAPHY: TIME FOR EEG2?

This article argues that recent proposals for environmental and evolutionary economic geographies (EEG 1 and EEG2) should be integrated; EEG² is used as “passing convenience” to make this case. EEG1's emphasis on environmental imperatives is loosely framed and needs a theoretical socio‐economic evolutionary base that is the central thrust of EEG2. Meanwhile EEG2 would be empowered by incorporating environmental concerns within its mandate. Moreover, both EEG1 and EEG2 share common roots in institutional methodologies, emphasize cumulative causation and path‐dependent behaviour, have strong interests at regional scales of analysis, and both are intimately tied to the causes and consequences of innovation. This article provides a rationale and suggests an integrative conceptual approach for developing EEG². In particular, the article outlines a conceptual framework that interprets EEG² in terms of co‐evolutionary socio‐ecological and multi‐scalar processes that are situated within a reasoned history interpretation of economic development. This framework further highlights the roles of path dependency, innovation, multinational corporations and value chains. How this multi‐scalar framework may be elaborated is then discussed around three themes: extending placed‐based analysis of localized clusters; broadening the scope of global value chain analysis; and re‐engaging the analysis of core–periphery relations. Ultimately the case for EEG² is to ensure that economic geographic perspectives are fully incorporated in debates over the co‐evolution of economy and environment, in research and policy terms one of, if not the, central challenges of development in the 21st century.     

Regulating commercial public service broadcasting: a case study of the marketization of Norwegian media policy

This article looks at the issues facing the regulation of commercial public service broadcasting in Norway. A document analysis of the 2010 renegotiation process to renew TV 2’s public service licence illuminates how a general marketization affects the regulation of the television sector. This process comments on Hallin and Mancini’s model of democratic corporatism in the Nordic countries regarding the power of the state to regulate private media enterprises as cultural institutions. As such, the process of commercialization should include not only the broadcasting sector, but also the political sector. As part of a solution to retain TV 2’s licence agreement, the government effectively had to re‐regulate the cable distribution sector. This case study demonstrates not only the enduring strength and value of the public service institution in a political context, but also the extent to which regulation is guided by technical and economic forces to sustain democratic considerations.     

Genesis for Historians: Thomas Abbt on Biblical and Conjectural Accounts of Human Nature

Summary

Natural sociability and the basic features of human nature stood at the centre of Thomas Abbt's confrontation with conjectural history, the popular eighteenth-century mode of reconstructing the evolution of human culture. Abbt (1738–1766) criticised conjectural histories due to their arbitrary character, and opted for a synthetic approach consisting of both sacred and secular history. He suggested that the anthropology of Genesis should be accepted as the starting point for a conjectural history, since it left ample room for further questions and speculations. Yet his own perspective on human nature and its evolution remained naturalistic, as attested by his divergent interpretations of the confusion of tongues at Babel. Attempting to shed new light on the lesser-known elements of Abbt's work, the essay links his views on the Bible and conjectural history to his debate with Moses Mendelssohn over the constitution and destination of man. In this debate, both Mendelssohn and Abbt dealt with the contemporary controversy over the natural or artificial character of sociability, self-interest, and fellow-feeling.     

Metastatic carcinoma in a 14th–19th century skeleton from Constância (Portugal)

During 2002, the extensive archaeological excavations of the ancient Constância necropolis (Centre of Portugal), dated from 14th–19th centuries, resulted in the exhumation of 151 individuals. Among the several paleopathological cases, a middle‐aged female skeleton with osteolytic lesions in her skull, axial skeleton, upper limbs and femurs was observed. These pathological findings are characterised by an asymmetric pattern with osteolytic focus of distinct size and irregular shape. Some skeletal elements display both osteolytic and osteoblastic lesions. The latter exhibit deposition of fine layers of woven bone. Lesions were observed macroscopically and radiology was used as a complementary method of scrutiny, especially in cases of unclear observation. The case was diagnosed as that of a probable metastatic carcinoma due to the multifocal distribution of the lesions in areas of intense haematopoietic activity, their morphology and some osteoblastic responses, as well as the presence of pathological fractures in the ribs. The skeleton's sex and age at death are in agreement with the proposed diagnostic, constituting the first case of malignant carcinoma detected in non‐identified Portuguese human skeletal remains.

Tectonic control over large-scale diffuse degassing in eastern Sicily (Italy)

Eastern Sicily (southern Italy) is characterised by the presence of many natural gas emissions (mofettes, mud volcanoes). These gases are mostly carbon dioxide and methane, with minor amounts of helium, hydrogen, carbon monoxide and hydrocarbons. In this study, the extent and orientation of soil gas anomalies (He and CO₂) were investigated on a wide area (approximately 110 km²) located just SW of Mt. Etna. From a structural point of view, this area lays on a typical foredeep–foreland system that marks the boundary between the southern part of the Eurasian plate and the northern part of the African plate in the central Mediterranean. No tectonic structure was revealed in this area by surface geological surveys. Very high soil emissions were found, and their spatial pattern reveals the existence of some active faults all directed about N50°E. This direction coincides with that of two major fault systems that cut eastern Sicily and are evident, respectively, NE and SW of the study area. Soil gas data suggest that these fault systems are the expression of a single continuous structural line which is probably responsible for the past and present magma uprise in eastern Sicily. Isotopic values of carbon of CO₂ suggest a minor contribution of organic carbon. Moreover, in the highest degassing sites the isotopic values of He found in association with CO₂ (He abundance = 11–70 p.p.m.; R/R_a between 6.0 and 6.2) suggest that both gases are mantle derived. The extent of the areas affected by high gas emissions and the amounts of deep CO₂ emitted in the investigated area (several hundred tonnes per day) may provide additional supporting evidence of a mantle upwelling taking place beneath this region.     

Specialized Early Upper Palaeolithic Hunters in Southwestern France?

Paul Mellars has long used cave and rockshelter ungulate faunal assemblages from southwestern France to argue that the early Upper Palaeolithic people of this region focused their hunting on reindeer (Rangifer tarandus), and that such specialized hunting distinguishes the Upper from the Middle Palaeolithic in at least this region. We examine this argument quantitatively, using a sample of 133 Mousterian, Châtelperronian, and Aurignacian ungulate assemblages. We show that only five Aurignacian assemblages, from three sites, stand out in terms of the degree to which their ungulate faunas are dominated by a single taxon. We also show that some Mousterian cave and rock shelter ungulate assemblages are more heavily dominated by large bovids than Aurignacian assemblages are dominated by reindeer, and that Mellars' argument is highly dependent on the exclusion of open sites from the analysis and on the numerical threshold he has selected to indicate hunting specialization.     

The Design and Development of a Closed Chamber for the in‐situ Quantification of Dryland Soil Carbon Dioxide Fluxes

This paper describes the design features and capabilities of a portable automated in‐situ closed chamber (ISCC) for the quantification of CO₂ fluxes in dryland soils where both photosynthetic and respiratory components may be associated with a cyanobacterial crust. The processes of CO₂ flux in dryland soils are briefly described in order to clarify the conditions that make quantification of these fluxes problematic. The instrumentation currently available for in‐situ soil CO₂ flux measurements is then reviewed demonstrating their inadequacies for the dryland environment. The ISCC described here is a member of the closed or enrichment class of soil respiration chambers. The ISCC, however, features an optical window possessing high (>90%) transmission in the photosynthetic active region (PAR) of the solar irradiance spectrum, permitting observations of photosynthesis. The ISCC possesses automatic venting and purging so that gaseous concentrations inside the chamber do not change from ambient sufficiently to significantly affect diffusion. The ISCC features both active and passive cooling employing internal solid‐state Peltier coolers and external aluminised Mylar respectively. This avoids severe disturbance of the microclimate within the chamber due to admission of high fluxes of PAR and permits in‐situ operation under a wide range of ambient field temperatures (~ ?5 to 40°C). Sensors internal to the chamber monitor temperature, relative humidity, irradiance and pressure. In this implementation the ISCC is coupled to a portable gas chromatograph (Agilent GC‐3000) to sample the chamber atmosphere. Indicative data for Kalahari Sand soils of Botswana are presented as an illustration of the general performance characteristics.
