Interpreting pachyderm single carcass sites in the African Lower and Early Middle Pleistocene record: A multidisciplinary approach to the site of Nadung’a 4 (Kenya)

Nadung’a 4 is one of the single carcass pachyderm sites recorded in East Africa during the Lower and Early Middle Pleistocene. The site has yielded an abundant lithic assemblage in close association with the partial carcass of an elephant. Conjoined pedological, geoarchaeological, spatial, technological, and taphonomical analyses have been carried out to address the relationship between hominids and elephant. The resulting data are consistent with a non-fortuitous association between both categories of remains. The lithic artefacts do not match a classical Acheulean tool-kit, as would be expected for the time period ascribed to the site, and the functional patterns inferred from their analysis make this site radically different from other purported butchery sites. The implications of these original features are discussed.     

The social networks of the Buckinghamshire gentry in the thirteenth century

This empirical study offers a contribution to a continuing debate about the county community and the significance of feudal ties by analysing the contacts of twenty small and middling knightly families. It explores their geographical range and the relative significance of horizontal and vertical ties. The evidence indicates a world dominated by local connections, stretching five to ten miles from a family manor. Nonetheless, the gentry were not necessarily restricted by county boundaries in their connections, as patterns of monastic patronage show. Nor were their social networks always limited to their neighbourhood. The search for good marriages mobilised wider networks, while financial pressures led families to look to towns like Oxford and London for credit. Ties with feudal superiors were rare, except for tenants of the honor of Wallingford, who had links with the earls of Cornwall. Horizontal ties with other gentry families and family members significantly outnumbered those with any other groups, and this applied both to supportive relationships and conflictual ones. Placing this study in the context of other gentry studies, I conclude by emphasising the prevalence of local ties mainly with those on the same social level or below. Although there is evidence to suggest that wealthier families with several manors had wider ranging connections, the everyday world of these men was apparently a fairly parochial one.     

A Minimum-Impact Method for Measuring Corrosion Rate of Steel-Hulled Shipwrecks in Seawater

Current research on USS Arizona is focused on a minimum-impact technique for calculating corrosion rate of the battleship's steel hull by analysing physical and chemical properties of marine encrustation covering the exposed hull. An equation is derived that allows concretion thickness, density, and total iron content to be used to calculate corrosion rate of steel hull plate.

Advising Howard: Interpreting changes in advisory and support structures for the Prime Minister of Australia

John Howard, Prime Minister for nearly a decade, leads a disciplined Cabinet and, save for a few recent rumblings, a united and orderly backbench. He runs a tightly controlled political and policy agenda that unmistakably bears his personal stamp. How can John Howard's authority be understood and explained? While undoubtedly the product of his personality and working style, his formidable political skills, experience and renowned personal discipline, it may also be attributable to the substantial and sophisticated advisory infrastructure developed to support his prime ministership. This article surveys the key institutions that provide advice and support for John Howard's prime ministership, and assesses their effectiveness.
