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.  相似文献

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.

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.  相似文献

Whilst greatly valuing recent critiques of the vertical imaginary and reified ontology of scale theory, and of the unfettered flows of network theory, this paper argues against a human geography without scale. Rather, four propositions from the theoretical literature are used to provide a tool-kit to analyse the practical negotiation of scalar politics, namely that: scales should be considered as effects, not frames or structures, of practice; networks must be considered in all their complexity and heterogeneity; networks can be interpreted as assemblages, the more re-territorialising and re-scaling of which can be analysed as apparatuses; and that state apparatuses work to create the impression that scales are ahistorical, hierarchical and possess exclusive relationships. These propositions are used to explore a period of history when the scalar constitution of the world was under intense debate. The interwar era saw the imperial scale clash with that of the international, both as ideological worldviews, and as a series of interacting institutions. The assemblages of internationalism and imperialism were embodied by apparatuses such as the League of Nations and the colonial Government of India respectively. Attempts by the League to encourage the abolition of tolerated brothels in an attempt to reduce the trafficking of women and children led to intense debates between the 1920s and 1930s over what constituted the legitimate domains of the international and the 'domestic'. These explicitly scalar debates were the product of League networks that threatened the scalar sovereignty of the Raj, most directly through the travelling Commission of Enquiry into Traffic in Women and Children in the East in 1931.  相似文献

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.  相似文献
