Pig domestication and husbandry practices in the middle Neolithic of the Wei River Valley,northwest China: evidence from linear enamel hypoplasia

Linear enamel hypoplasia is a physical deficiency occurring during the process of enamel formation and it is visible on the crowns of mammal teeth. It can be used to trace physical stresses during life. In this study, linear enamel hypoplasia in samples of pigs from three Neolithic sites in the Wei River valley (China) were recorded and analysed, to investigate the status of pigs at these sites, their living conditions, and furthermore to explore husbandry strategies for pigs during the Neolithic in the valley. The results suggest a domesticated status for pigs in the Neolithic and early Bronze Age. Also the frequency of LEH occurrence for the pigs corroborates a presumed intensification processes of pig husbandry, and the presence of environmental fluctuations during the period are considered. Some evidence also points to the fact that for pig, spring farrowing was the most common reproductive strategy in the Neolithic and early Bronze Age in this region.     

Motives and opportunities for domestication: an ethnoarchaeological study in southwest Ethiopia

Farmers of southwest Ethiopia are currently transplanting yams (Dioscorea cayenensis) from wild contexts to home gardens. Ethnoarchaeological study of this practice can inform considerations of agricultural origins in prehistoric times by revealing motives and opportunities that shape decisions to adopt wild-growing plants. In one part of the study area, case studies demonstrate that decisions to manipulate yams may arise mainly among individuals of a particular gender or household composition. Comparisons across the study area illustrate the effects of slight variations in environment and human mobility upon adoption of wild-growing yams. The social and environmental factors that favor or impede manipulation of yams are highly specific and nuanced, and operate on both intra- and inter-community levels.

Identifying donkey domestication through changes in cross-sectional geometry of long bones

The initial phases of donkey domestication are difficult to identify in the archaeological record due to late and inconsistent changes in morphology and body size in the earliest domestics. Use of donkeys for load carrying and the management of captive herds resulted in a distinctive behavioral shift away from the free-ranging speed and mobility characteristic of wild asses toward slower, more steady pacing. Given the ability of bone to adapt to its mechanical environment, bone remodeling in the limbs of wild asses and donkeys are evaluated using cross-sectional geometry to determine whether weight bearing or locomotor differences between the wild and domestic forms may be used to recognize early domestication. Cross-sectional data were collected on the humeri, radii, metacarpals and metatarsals of eight wild ass and six donkey skeletons. Wild ass forelimbs have greater overall strength and more cylindrical humeral diaphyses, indicating better resistance to a varied locomotor repertoire. These results demonstrate that analyses of shaft geometry can provide information on changes in locomotor behavior during domestication. Our finding that shifts in gait had greater effects on the morphology of early domestic donkeys than did load-carrying places a new emphasis on understanding selection for gait changes in domestication dynamics.     

Methodology,consetvation criteria and performance evaluation for archaeological site shelters

Abstract

The many intersecting issues that arise when deciding whether to shelter an archaeological site should be approached using a values-based methodology, one that has demonstrated its validity arid practical worth in conservation over recent decades. Nonetheless, pitfalls abound in the decision-making process and in establishing effective conservation criteria which should be based principally on a thorough understanding of the threats to the resource and the specific deterioration mechanisms operating, with the objective of creating a shelter that will preserve the site's identified values. An aspect that has received almost no attention in the past is evaluation of a shelter's performance, both qualitative and quantitative, in preserving the site. It is urged that this receive priority when establishing the conservation criteria during the initial phases of a sheltering project. Issues are illustrated from a range of diverse sites, including a number of published shelters. The paper first looks at the examples of the Laetoli (Tanzania) and Lark Quarry (Australia) trackway sites in the context of decision-making and conservation criteria, and then discusses two examples of evaluation: one quantitative, using an experimental shelter and the other discussing publications on a petroglyph site shelter.     

Diagnostic criteria for identification of seashell as a trephination implement

Scanning electron microscopy has been applied to experimentally cut bone samples and an ethnographical example of trephination on a human skull in order to produce diagnostic criteria for the identification of mollusc shells as cutting implements used in trephination. Shell scrapes are identifiable by parallel striations in the direction of cut, crossed at 90° by chatter marks caused by uneven movement of the fragile shell-edge across the bone surface.     

Teotihuacan pottery as evidence for subsistence practices involving maguey sap

As in most other pre-industrial cities, urban life at Teotihuacan was closely intertwined with ceramic technology, perhaps nowhere more so than in the realm of foodways. Here, we use two kinds of information derived from ancient pottery—ceramic residues and intra-site sherd distribution patterns—to shed new light on the city’s subsistence economy. We concentrate in particular on the amphora, a type of vessel that may have been used to contain aguamiel and pulque, liquid foodstuffs made of maguey sap. Distributional data distilled from surface collections of the Teotihuacan Mapping Project are informative about patterned variation in the use of these pots at the scale of the entire city. More focused analyses are aimed at chemical characterization of organic residues preserved in ceramic sherds recovered from recent excavations. Part of a broader project aimed at identifying both animal and plant remains, the results of the residue analysis provide the first direct identification of pulque remains in Teotihuacan pottery.     

Measured domestication rates in wild wheats and barley under primitive cultivation,and their archaeological implications

Man's (or, more probably, Woman's) first cereal crops were sown from seed gathered from wild stands, and it was in the course of cultivation that domestication occurred. Experiments in the measurement of domestication rates indicate that in wild-type crops of einkorn, emmer, and barley under primitive systems of husbandry: (a) domestication will occur only if they are harvested when partially or nearly ripe, using specific harvesting methods; (b) exposure to shifting cultivation may sometimes have been required; and (c) under these conditions, the crops could become completely domesticated within 200 years, and perhaps only 20–30 years, without any conscious selection. This paper (a) considers possible delays in the start of domestication due to early crops of wild-type cereals lacking domestic-types mutants; (b) examines the husbandry practices necessary for these mutants to enjoy any selective advantage; (c) considers the state of ripeness at harvest necessary for the crops to respond to these selective pressures; (d) outlines field measurements of the selective intensities arising from analogous husbandry practices applied experimentally to living wild-type crops; (e) summarizes a mathematical model which incorporates the measured selective intensities and other key variables and which describes the rate of increase in domestic-type mutants in early populations of wild-type cereals under specific combinations of primitive husbandry practices; (f) considers why very early cultivators should have used those husbandry methods which, we suggest, led unconsciously to the domestication of wild wheats and barley; and (g) considers whether these events are likely to leave archaeologically recognizable traces.

Geographies of asylum, legal knowledge and legal practices

Law and legal discourses are an integral part of social life, a central means of producing social identities and exercising social power in day to day life. Critically informed geographical perspectives on law have illustrated in a number of ways how the legal and social (and therefore the spatial) are mutually constitutive. This paper argues that perspectives from critical legal geography can offer insights into the operation of asylum and immigration law in the UK in the late 1990s. This paper argues that legal practices and relations are organised in hegemonic and counter-hegemonic ways in different places and institutional contexts in London. In addition law and legal practices comprise a particularly important way in which ‘community’ can be constructed simultaneously across a variety of different scales in ways that can marginalise and exclude relatively powerless groups like asylum seekers. Thus refugee identities offer a particularly clear example of how social realities are constituted by law and legal practice.     

Establishing collagen quality criteria for sulphur isotope analysis of archaeological bone collagen

Sulphur isotope measurements of bone collagen from archaeological sites are beginning to be applied more often, yet there are no clear criteria to assess the quality of the collagen and therefore the validity of the sulphur isotope values. We provide elemental data from different methods (DNA sequences, amino acid sequences and mass spectrometric measurements) which are used to establish a reliable system of quality criteria for sulphur isotope analyses of bone collagen. The difference in the amount of sulphur from fish and mammalian collagen type I led to the suggestion to use different criteria to assess the in vivo character of the collagen between these two categories. For establishing quality ranges, the bone collagen of 140 modern animals were analysed. The amount of sulphur in fish and mammalian bone collagen is 0.63 ± 0.08% and 0.28 ± 0.07%, respectively. Based on these results we define for mammalian bone collagen an atomic C:S ratio of 600 ± 300 and an atomic N:S ratio of 200 ± 100, and for fish bone an atomic C:S ratio of 175 ± 50 and an atomic N:S ratio of 60 ± 20. These quality criteria were then applied to 305 specimens from different archaeological contexts.     

Legal hyper-invasiveness and anti-legal practices in contemporary Italy

This paper gives an illustration of legal hyper-invasiveness in Italy over the course of the last decades, with particular emphasis on the increase in laws and law-producing institutions: neoliberal governmentality is not characterized by a retreat of the State, rather by the extent of its reach and force. The success of legal imposition has always been partial; in recent years, however, anti-legal constituent praxes are becoming more evident both in public demonstration and in everyday conduct. Street mobilizations are fuelled increasingly by disillusion with institutional politics, pursuing explicit anti-legal aims and marked by an autonomy from political parties and trade unions. The paper also provides an ethnographical examination of the day-to-day avoidance of institutional control, revealing a growing and widespread sense of intolerance of several regulations promoted by the institutional powers. Finally, contemporary forms of repression of these constituent energies are examined; and the belief that an increase in legality will benefit citizens is questioned.
