Paleodiet reconstruction of Bronze Age Siberians from the mortuary site of Khuzhir-Nuge XIV,Lake Baikal

Paleodiet reconstruction using stable isotopes of carbon and nitrogen was carried out on individuals from the Bronze Age cemetery, Khuzhir-Nuge XIV on the western shore of Lake Baikal, Russian Federation. The cemetery contained 79 graves with 89 individuals and was in use between approximately 2700 and 2000 cal. B.C. with the exception of one burial, dated to around 4000 B.C. Archaeological and ethnographic evidence indicates that hunting and fishing were the main subsistence activities while gathering was less important. δ¹³C from collagen and carbonate apatite was analysed, along with δ¹⁵N from collagen. Bone mineral preservation was evaluated using Fourier transform infrared spectroscopy. δ¹³C and δ¹⁵N of collagen are positively correlated and reflect varying reliance on terrestrial mammals, fish, and seals from Lake Baikal. Lake Baikal biota exhibit considerable variation in δ¹³C at the base of the food web thus; there is variation in human δ¹³C (−20.1‰ to −16.2‰) despite the fact that there are no C₄ plants in the region. δ¹⁵N results (range 10.3‰–16.5‰) indicate that fish, and possibly seals, made up some of the diet for everyone, but in varying amounts relative to terrestrial herbivores. δ¹³C from carbonate is not correlated with δ¹³C from collagen, a situation that has been found in remains from other coastal sites. A mixed diet from both terrestrial and freshwater ecosystems is the most likely explanation. Analysis of mortuary variables within the cemetery reveals three distinct clusters of graves with variations in burial treatment among the clusters. δ¹⁵N values are significantly different among these clusters, suggesting an association between diet and mortuary customs.

Systematic seasonal land use by late Pleistocene Tasmanian Aborigines

New research on the odontochronological (dental growth-increment) analysis of marsupial teeth provides opportunities to estimate with more certainty the time of the year Tasmanian Aborigines inhabited sites during the late Pleistocene. Here we focus on the Bennett's wallaby (Macropus rufogriseus) as a proxy for understanding seasonal human land use patterns and occupation of four southwest Tasmanian caves. The aim of the paper is to investigate whether caves at different altitudes were occupied in alternating seasons, and determine if the ‘Patch Model’ developed to explain the archaeological variability of late Pleistocene human behavior should be modified accordingly. The data presented here support the original observations that these sites, although reflecting extreme richness, were occupied in a punctuated seasonal manner with visits probably separated by a considerable time of unknown duration.     

Strategies of learning in the process of transformation

The paper deals with the learning and innovation strategies of manufacturing companies in the economies of transformation. The point of departure is the development of a theoretical framework dealing with innovation, knowledge and learning. The case is of two manufacturing companies in Poland, the learning strategies of which are analysed and compared. These strategies have much in common and can be seen as quite successful. Global knowledge sourcing has become important. Some common problems also exist in relation to mismatches within and between the different knowledge bases. More selective and specialized strategies of learning are recommended to enhance the competitiveness of the companies.     

Sailing virtual canoes across Oceania: revisiting island accessibility

Understanding sailing conditions is a basic requirement for understanding the two periods of settlement of the distant islands of Oceania, initially from the Bismarck Islands off New Guinea as far as Samoa and later from Samoa throughout East Polynesia. The question of a “navigational threshold” between these two worlds is the focus of this paper. A computer simulation is presented that quantifies the difficulty of sailing virtual canoes in the differing wind conditions in both areas. The model demonstrates substantial differences in ease of voyaging up to and beyond Samoa. That this measure is so markedly different between these two worlds gives support for the hypothesised pause between the discovery and settlement of islands West and East of Samoa.     

An Iron Age II snake cult in the Oman peninsula: evidence from Bithnah (Emirate of Fujairah)

Excavations carried out by the French Archaeological Mission at Bithnah-44/50 (Emirate of Fujairah) have provided new data about Iron Age II cultic practices in the Arabian Peninsula centred on the symbol of the snake. The site includes a public building, various types of shrines, and a central area of offerings where the remains of animal sacrifices were buried in pits. These remains are presented and a preliminary account of the evolution of the site is given on the base of the site's stratigraphy.
