Extreme osteoporosis in a sixth century skeleton from the Negev desert

Osteoporosis was probably rare in ancient times due to the short life expectancy. An extremely osteopaenic skeleton of an adult female who lived in the Negev Desert c. AD 500 was studied using radiology, bone densitometry and histomorphometry. Possible aetiologic factors are discussed, with special emphasis on calcium and/or vitamin D deficiency, because nutritional deficiency has been described in Bedouin women who retain traditional dietary habits resembling those prevalent in the Negev region in antiquity.     

Assessing mussel shell diagenesis in the modern vadose zone at Lyon's Bluff (22OK520), Northeast Mississippi

This study considers the chemical alteration of archaeological freshwater shell above the water table at the Lyon's Bluff site (22OK520), a single-mound and village complex located in east-central Mississippi, and the changes in trace element concentrations between unfired and fired shell. Thin-section petrography, X-ray diffraction, cathodoluminescence, and scanning electron microscopy analyses were conducted on archaeological shell from four natural layers from Unit 20N20W, over a depth of 80 cm and spanning 450 years. ICP–MS analysis also was conducted on a modern freshwater shell subjected to kiln firing. Microscopy results indicate a pristine aragonite crystal structure in the archaeological samples. ICP–MS data show that certain trace elements within the modern shell maintain their concentration after firing at 500 °C. The broader implications are: 1) that diagenetic alteration does not hinder chemical sourcing of shell at Lyon's Bluff, and 2) that certain trace elements are more reliable than others, namely Sr²⁺, Al²⁺, Ba²⁺, and Mn²⁺, when conducting trace element provenance studies on fired-shell temper.     

The vague nouvelle and the Nouvelle Vague: The Critical Construction of le jeune cinéma français

One of the commonplaces in critical writing on the 1990s movement known as le jeune cinéma français is the idea that it constituted a new ‘New Wave’. At the same time, the critical reception of the 1990s and 1960s ‘new waves’ could not be more different, with le jeune cinéma français being seen invariably as aesthetically inferior to its 1960s ‘antecedent’. This article examines the two key discursive mechanisms used to link le jeune cinéma français to the Nouvelle Vague, those of political commitment and ‘auteur’ cinema. It is argued that the mechanisms used to construct le jeune cinéma français as a distinct cinematic category become increasingly divorced from the kinds of films actually being made and that it is this discursive disjuncture which is, in part, responsible for its negative critical reception.     

ON THE IMPACT OF LABOR MARKET MATCHING ON REGIONAL DISPARITIES*

ABSTRACT We propose a model where imperfect matching between firms and workers on local labor markets leads to incentives for spatial agglomeration. We show that the occurrence of spatial agglomeration depends on initial size differences in terms of both number of workers and firms. Allowing for dynamics of workers' and firms' location choices, we show that the spatial outcome depends crucially on different dimensions of agents' mobility. The effect of a higher level of human capital on regional disparities depends on whether it makes workers more mobile or more specialized on the labor market.
