Flint and Quartzite: Distinguishing Raw Material Through Bone Cut Marks

Since the 1980s, several experimental analyses have been able to differentiate some lithic tool types and some of their raw materials according to the morphology of cut marks imprinted by such tools when used for butchering activities. Thus, metal tool use has been differentiated in contexts with an abundance of lithic tools, or even the use of hand axes has been documented in carcass processing, in contrast with simple unretouched or retouched flakes. As important as this information is, there are still other important aspects to be analysed. Can cut marks produced with different lithic raw material types be differentiated? Can cut marks made with different types of the same raw material type be characterized and differentiated? The objective of this study is to evaluate if cut marks resulting from the use of different flints and different quartzites are distinguishable from each other. In the present work, an experimental analysis of hundreds of cut marks produced by five types of flint and five varieties of quartzite was carried out. Microphotogrammetry and geometric–morphometric techniques were applied to analyse these cut marks. The results show that flint cut marks and quartzite cut marks can be characterized at the assemblage level. Different types of flint produced cut marks that were not significantly different from each other. Cut marks made with Olduvai Gorge quartzite were significantly different from those produced with a set comprising several other types of quartzites. Crystal size, which is larger in Olduvai Gorge quartzites (0.5 mm) than Spanish quartzites (177–250 μm), is discussed as being the main reason for these statistically significant differences. This documented intra‐sample and inter‐sample variance does not hinder the resolution of the approach to differentiate between these two generic raw material types and opens the door for the application of this method in archaeological contexts.     

The Disappearing State and the Quasi‐Event of Immigration Control

Immigration enforcement by sheriffs and police can be characterized as a proliferation of quasi‐events which never quite rise to the status of an event. This poses distinct challenges for feminist‐inspired scholarship on the state which seeks to document, ethnographically, how the state goes about its business on the ground. In this article we draw on our fieldwork experience in North Carolina and Georgia on sheriffs’ and police departments’ use of traffic enforcement and policing roadblocks to scrutinize drivers for their legal status, and ask how our ethnographic approach to the problem of state power inevitably stumbles in relation to the ordinariness of these practices. We conclude that feminist scholarship committed to an ethnography of the state could do much more to think through the potentially aporetic quality of that which is our common object of research—the state in practice.     

Obtaining Black Carbon—A Simple Method for the Safe Removal of Mineral Components from Soils and Archaeological Layers

In this study, we present a novel, safe method for how to remove inorganic components from soil samples studied for archaeological purposes, in order to improve studies of the distribution of black carbon in the sedimentary record. As the depositional history of this material depends on the interaction between humans and the natural environment, this method can be widely used in archaeology, landscape archaeology, palaeoecology, environmental geology and sedimentology. Our method does not require the use of dangerous hydrofluoric acid, which is commonly used for the removal of silicon oxide from such samples; therefore, this procedure allows even less chemically trained scientists to analyse soil samples with an increased level of work safety.     

Marital distance and its geographical orientation in England and Wales, 1979

"A representative sample of just over one thousand marriages solemnized in England and Wales in 1979 is used to analyse the distribution of the distances between the partners' addresses at marriage....according to various social and demographic variables also derived from the same source. Comparison with other surveys suggests that marriages in which both partners give the same address are likely to be those of couples who cohabit before marriage. Partners who work in unskilled manual occupations, or who marry with a civil ceremony, or who have been married before, appear more likely than the average to cohabit. Of the marriages where different addresses are given, about one-half bring together partners living within 5 km of each other." It is found that "there is a strong relationship between high social class and increased marital distance, and also between greater marital distance and older ages up to about age 40. Longer-range marriages show clear evidence of geographical orientation, the effect being more pronounced at longer distances. This is attributed to variations in population density over the country and geographical constraints on settlement patterns."
