Late Silurian and Early Devonian biostratigraphy in the Hill End Trough and the Limekilns area,New South Wales

Precordilleran Late Palaeozoic brachiopod genera considered for this palaeobiogeographical analysis belong to four faunal associations: the low diversity Early Carboniferous (Tournaisian) Protocanites scalabrinii-Azurduya chavelensis Zone; the Late Carboniferous (Bashkirian-Moscovian) Levipustula fauna, which appears in sequences associated with glacial intervals; the latest Carboniferous-earliest Permian (Gzhelian-Asselian) Rhipidomella-Micraphelia and Tuberculatella-Aseptella associations, and the Early Permian (mid to late Asselian) Tivertonia jachalensis-Streptorhynchus inaequiornatus Biozone. The brachiopod affinities of the Precordillera are compared with the biogeographical Late Palaeozoic regions previously suggested by other authors using cluster analysis. During the Bashkirian-Moscovian, the Precordilleran faunas show a high affinity with the Austral Realm because of the presence of the Levipustula faunal elements in Eastern Australia. At the same time the affinity with the central and North American Regions is very low. The Early Permian Precordilleran faunas demonstrate highest affinity with the Gondwanan Realm with several genera also linked to the Tethyan and Boreal Realms. After the Late Carboniferous glacial episodes that affected the southwestern Gondwanan margin, the Precordilleran region underwent climatic amelioration. Subsequently, the Early Permian Precordilleran brachiopod assemblages are characterized by typical cool to cold water genera widely developed in the core Gondwanan Realm, with fewer genera (such as Kochiproductus, Rhynchopora and Neochonetes) suggesting a warmer water influence. The Precordilleran faunas demonstrate an increase in brachiopod diversity from the Carboniferous to the Permian, related to water temperature changes and to the palaeogeographical evolution of the southwestern Gondwanan margin and the movement of Gondwana across the South Pole.     

Reflections on Collaborative Archaeology and Large-Scale Online Research Infrastructures

ABSTRACT

The Archaeology Data Service (ADS) is an archive working at a national level in the UK, ensuring that archaeologists have access to high quality and dependable digital resources, including openly licensed legacy data for reuse. The ADS acts as a metadata aggregator for archaeological data held by larger heritage agencies and smaller regional organizations and participates in international aggregation infrastructure projects such as ARIADNE, which allows users to access archaeological resources held in many countries from a single interface. Large-scale infrastructures can facilitate the building of long-term, complex relationships and active collaborations, not just technical solutions. This paper reflects on the roles of stewardship and equity within ARIADNE and the ADS, two large-scale online research infrastructures, and how these types of infrastructures may help to create a more collaborative archaeology, including lessons learned, challenges and opportunities, and thoughts for the future.     

Gender Awareness in Migration Theory: Synthesizing Actor and Structure in Southern Africa

Recent developments in migration theory mirror two concerns writ large across the development literature, namely the attempt to reconcile structure and agency and the importance of gender. Using the specific context of southern Africa, this article analyses the development of migration theory over the last forty years and the dialectic between gender and the structure-agency dyad. It is argued that gender is an essential tool for unpicking the migration process and that a gender perspective has enriched and been enriched by a model of migration allowing analytical space for both the agency of migrants and the structures which surround them. Juxtaposing the various theories which have been brought to bear on migration in southern Africa also reveals the extent to which new models and classificatory systems have developed on the basis of agendas set by preceding conceptual frameworks, distinctions between competing models rarely being as clear-cut as the mode of scholarship would have them appear.     

Crossing the Factory Frontier: Gender, Place and Power in the Mexican Maquiladora

A pressing question raised by contemporary feminist theorists is how to conceptualize the intricate relationship between women as social agents and "Women"— an ideological representation of a female subject. Scholars have shown how women must often disavow this Woman in trying to establish their own careers. This article explores one facet of this issue by tracing one woman's journey through a Mexican maquiladora in the hope of demonstrating how this ideology produces the capitalist division of labor through the reproduction of sex-difference, nationality, and ethnic categories within one firm. The account raises some interesting questions about resistance, which may not be resolvable in the context of the workplace alone.
