BARNSLEY PARK VILLA; ITS INTERPRETATION AND IMPLICATIONS

The Roman villa at Barnsley Park was interpreted by its excavator as a farm run by a family and a body of workers, its distinctive archaeological features being the division into three yards and the existence of a number of circular structures described as pens. An alternative hypothesis envisages a kin-group, the 'pens' being the houses associated with three farmyards. The three families are presumed to have held and worked the surrounding land in some kind of joint proprietorship. This system became Romanised as a hall-type villa designed for the occupation of some modified form of the kin-group.     

ROCK PHYSICS AND THE NEOLITHIC AXE TRADE IN GREAT BRITAIN*

This paper is concerned with the products of a number of Neolithic quarries in highland Britain. It investigates the claim that the scale of axe distribution was partly the result of social factors which resulted in these artefacts gaining an added value in areas remote from their sources. One case study considers the sequence of production in Cumbria, in relation to the tensile strength of the rock quarried in different parts of the region. It shows that these considerations had only a limited influence over the choice of stone source and the scale on which it was worked. A second study compares the tensile strength of the main raw materials used for making non-flint axes with the extent to which these sources were actually exploited. Again there is only a limited relationship between the two, suggesting that social factors may indeed have been important.     

EVALUATION OF THE MANGANESE ESR METHOD OF MARBLE CHARACTERIZATION

Results suggest that ESR studies of Mn⁺² in marble can provide an excellent discriminator for the determination of marble provenance. In comparison with other methods of quantitative analysis for manganese such as AA or NAA, the ESR method determines only Mn⁺² rather than total Mn, is inexpensive and rapid with no chemical preparation required, and does not consume the sample.     

GAS LIQUID CHROMATOGRAPHIC ANALYSIS OF FATTY ACIDS IN FOOD RESIDUES FROM CERAMICS FOUND IN THE SOUTHWESTERN CAPE,SOUTH AFRICA

Gas liquid chromatography was used to analyse residues adhering to the inside of excavated potsherds from dated South African sites. The results suggested marine animal fat, possibly seal, had been cooked in the vessels. Fat of modern seals was baked and also analysed as a control sample. This gave similar results. The importance of seals in the prehistoric diet of the Southwestern Cape is supported by a large number of seal bones in the associated faunal material.     

Some medieval Yemenite numismatic problems – observations on some recently sold coins

The article addresses some of the problems arising from the publication of a recent numismatic catalogue including coins from all parts of the Islamic world. The problems concern in particular the coins of the medieval Yemen and the article comprises a critique of those coins listed under the Arabian peninsula and the Yemen.
Catalogue nos. 101 and 104 are dealt with in some detail since they are erroneously ascribed to mints in Mecca and Minā, respectively. The former is struck in the name of a Zaydī imam, the latter is Rasulid and labelled as having been struck "for a special occasion". The intriguing question of the mysterious Ayyubid prince, al-'Ādil Abū Bakr, arises too (nos. 125 etc.), although no definitive answer can yet be suggested. Much more information is now available on the striking of coins in Tha'bāt during Rasulid times. A number of other points bearing on the numismatics, the history, and the geography of the medieval Yemen are discussed in the article.     

Is Von Thunen Alive and Well? A Transport-Cost Surface for South Australian Wheat

Economic geography has undergone a number of paradigm shifts since the Von Thunen model was at the peak of its popularity in the 1960s and 1970s. This study examines the cost of moving wheat from farm to ship in South Australia and constructs a transport-cost surface for the season 1991/92. Transport costs still exert a very important influence on farm returns and land values. Governments and other authorities, when making decisions in the name of rationalisation, or microeconomic reform, should examine very carefully the spatial consequences of their actions. In the short-run at least, the farmer's world is very much a normative and partial equilibrium one. At least in respect of a significant Australian agricultural enterprise, normative and partial equilibrium models should not be seen as obsolete.     

STABLE ISOTOPE INVESTIGATIONS OF THE DANEBURY HILLFORT PIT BURIALS

Carbon and nitrogen isotope analyses were performed on human and animal bones recovered from pits within Danebury Iron Age hillfort. All results are within the range expected for European Holocene specimens and are similar to those from other Iron Age sites in central southern Britain. Our results indicate that the human diet included a significant amount of animal protein (meat and/or dairy products) consumed on a regular basis, but do not preclude a diet based heavily on cereal consumption. In comparison with the extensive heterogeneity visible in the animal isotope values, the homogeneity of the human values is rather striking. This may be a reflection of the much slower turnover rate of adult human collagen and may also indicate that the humans consumed a much greater variety of food than the fauna (thus averaging many isotopic sources). This is consistent with the role of hillforts as central places and locations for food distribution and exchange.     

Assessing Socio‐Economic Vulnerability to Climate Change Impacts and Environmental Hazards in New South Wales and Queensland,Australia

This article systematically reviews and synthesises academic, peer‐reviewed literature to assess the state of knowledge concerning socio‐economic vulnerability to climate change impacts and environmental hazards in New South Wales and Queensland, Australia. It focuses upon empirical research that identifies socio‐economic factors associated with vulnerable subpopulations. Using systematic review methods, 35 articles met the inclusion criteria. These articles are analysed according to their general characteristics, the methods used, and the factors reported to be associated with socio‐economic vulnerability. This body of evidence reveals that (1) the majority of the knowledge about socio‐economic vulnerability in New South Wales and Queensland has only recently emerged; (2) more knowledge has been published about Queensland; and (3) extreme temperature is the most researched environmental hazard. Despite increased research activity over time, the number of factors repeatedly demonstrated to influence socio‐economic vulnerability is small. Age, gender, place of residence, and pre‐existing illness were the most commonly reported factors, although the influence of these factors upon socio‐economic vulnerability is complex. There is scope to extend the empirical research base across a broader range of climate‐related hazards and to better link findings from the domains of climate change vulnerability and population health.
