The Risks and Uncertainties of Migration: an Exploration of Recent Trends amongst the Wosera Abelam of Papua New Guinea

This paper reports on ongoing research on migration and circulation between the Wosera sub-district, East Sepik Province, Papua New Guinea, and the island province of West New Britain. We examine the pressures contributing to increased family migration and longer-term, possibly permanent, migration from the Wosera. While rising resource/population pressure and stricter forms of land tenure arrangements are altering patterns of out-migration, the situation for long-term and temporary migrants in West New Britain is becoming less certain as land shortages begin to limit opportunities for further settlement and indigenous landowners become less tolerant of migrants from other provinces. We discuss these influences on migration patterns within the context of emerging social stratification of Wosera society, and consider the implications for both migrants and non-migrants.     

The Navarino Naval Battle Site, Greece—an Integrated Remote-Sensing Survey and a Rational Management Approach

An integrated remote-sensing survey was carried out in Navarino Bay, where in 1827 a battle was fought between the allied British, French and Russian navies and the Turkish-Egyptian fleet. Integration and interpretation of the remote-sensing data has shown the presence of shipwreck remains on the sea-floor and possible shipwrecks buried under the sea-bed. It has also shown that the historical remains are under threat from the heavy anchors of tankers which sink into the sea-bed and, when dragged, dig furrows, thus disintegrating the shipwreck remains. To protect the sites the construction of permanent anchoring systems away from the shipwreck remains is recommended.

Participation and Power: Poor People's Engagement with India's Employment Assurance Scheme

‘Participation’ has become an essential part of good developmental practice for Southern governments, NGOs and international agencies alike. In this article we reflect critically on this shift by investigating how a ‘participatory’ development programme — India's Employment Assurance Scheme (EAS) — intersects with poor people's existing social networks. By placing the formalized process of participation in the EAS within the context of these varied and uneven village–level relationships, we raise a number of important issues for participatory development practice. We note the importance of local power brokers and the heterogeneity of ‘grassroots’ (dis)empowerment, and question ideas of power reversals used within the participatory development literature.     

Identifying the geochemical taphonomy of the osteological material from Katsambas rockshelter

We report analytical work undertaken in order to identify the geochemical taphonomy of the osteological collection (human and animal bones) recovered from a 1950s excavation at Katsambas, a small cavity in the marly limestone on the west bank of Kairatos River, Crete. The site had funerary use and yielded material of Neolithic and Minoan age with poor stratigraphical association. Disintegration of provenance labels from bags has introduced further uncertainty about the contexts of recovery. Samples of human and animal bones that macroscopically appear to belong to three taphonomic categories were studied by means of FT-IR spectroscopy, TEM microscopy and REE analysis to explore the taphonomical processes the bones have undergone. Although not novel in palaeontological research the use of REE opens a new path to investigating poorly provenanced osteological collections from old excavations. Such geochemical work offers a proxy to their relative dating through the evaluation of the time span bones have remained in the sediments and their respective taphonomic histories.     

Introducing δSr analysis in archaeology: a demonstration of the utility of strontium isotope fractionation in paleodietary studies

Isotopic methods are widely used in archaeology to investigate paleodiet. Here, we present a new method to identify trophic level in archaeological human populations and to investigate paleodiet. We demonstrate that strontium isotope compositions (reported as δ^88/86Sr) vary in a mass-dependent manner with increasing trophic level and can elucidate paleodiet in archaeological human populations. We present new mass-dependent strontium isotope data from tooth enamel and bone from individuals buried during the Late Intermediate Period (c. AD 1000–1300) in the large cemeteries of Chiribaya Alta, Chiribaya Baja, San Gerónimo, and El Yaral in the Ilo and Moquegua Valleys of southern Peru. We compare these data to radiogenic strontium isotope data (⁸⁷Sr/⁸⁶Sr) and light stable isotope data (δ¹⁵N_col and δ¹³C_col) from the same individuals to investigate geologic variability in strontium sources as well as marine food consumption among the Chiribaya. Our results demonstrate the utility of measurements of strontium isotope fractionation as a new tool for archaeological investigation of paleodiet. Importantly, this new technique can be used to generate paleodietary (δ^88/86Sr) and paleomobility (⁸⁷Sr/⁸⁶Sr) data from the same specimen, minimizing destructive analyses of invaluable archaeological material, and provides a new way to examine paleodiet through hydroxyapatite, which is particularly important when collagen is poorly preserved.     

Atlantic salmon, archaeology and climate change in New England

A paucity of archaeological remains of Atlantic salmon in Northeast North America has been cited as evidence that the species may have been present in the region only during and after the Little Ice Age (ca. 1450–1850 AD), one of coldest periods of the Holocene. However, significant problems of preservation, recovery and identification remain. Here, improved methods of identification use vertebra structure to distinguish salmon from trout, and strontium/calcium ratios to differentiate sea-run from landlocked salmon. In addition to the Little Ice Age, Atlantic salmon is identified in tightly dated contexts at 7000–6500 and 3500–3000 calendar years BP, during climate periods that were comparatively warm and wet.
