Biogeographic models of gene flow in two waterfowl of the Australo-Papuan tropics

There are many large, easy-to-observe anseriform birds (ducks, geese, and swans) in northern Australia and New Guinea and they often gather in large numbers. Yet, the structure of their populations and their regional movements are poorly understood. Lack of understanding of population structure limits our capacity to understand source-sink dynamics relevant to their conservation or assess risks associated with avian-borne pathogens, in particular, avian influenza for which waterfowl are the main reservoir species. We set out to assess present-day genetic connectivity between populations of two widely distributed waterfowl in the Australo-Papuan tropics, magpie goose Anseranas semipalmata (Latham, 1798) and wandering whistling-duck Dendrocygna arcuata (Horsfield, 1824). Microsatellite data were obtained from 237 magpie geese and 64 wandering whistling-duck. Samples were collected across northern Australia, and at one site each in New Guinea and Timor Leste. In the wandering whistling-duck, genetic diversity was significantly apportioned by region and sampling location. For this species, the best model of population structure was New Guinea as the source population for all other populations. One remarkable result for this species was genetic separation of two flocks sampled contemporaneously on Cape York Peninsula only a few kilometers apart. In contrast, evidence for population structure was much weaker in the magpie goose, and Cape York as the source population provided the best fit to the observed structure. The fine scale genetic structure observed in wandering whistling-duck and magpie goose is consistent with earlier suggestions that the west-coast of Cape York Peninsula is a flyway for Australo-Papuan anseriforms between Australia and New Guinea across Torres Strait.

Embedded in the land: customary social relations and practices of resilience in an East Timorese community

Drawing on a case study of Cacavei, a rural subsistence community in Timor-Leste, this article explores the mutually constitutive relationship between people and land within customary forms of society. Patterns of land use and connection to land are not simply reflective of genealogical modes of social organisation, but are also enabling of them. Particularly, the embedding of ancestors within the land offers a means of accessing kinship relationships beyond the genealogical present. Embeddedness provides a quality of embodiment that makes ancestors active participants in social life. Constituted in the relational nexus of people and land, forms of social organisation in Cacavei have a mutability which goes some way to explaining the community’s resilience in spite of forced displacement and cultural disruption during the period of Indonesian occupation. This mutability might be considered more broadly as a source of resilience for customary communities grappling with modernising processes of change.

The inter-section of political history and health policy in Asia - the historical foundations for health policy analysis

One of the challenges for health reform in Asia is the diverse set of socio-economic and political structures, and the related variability in the direction and pace of health systems and policy reform. This paper aims to make comparative observations and analysis of health policy reform in the context of historical change, and considers the implications of these findings for the practice of health policy analysis. We adopt an ecological model for analysis of policy development, whereby health systems are considered as dynamic social constructs shaped by changing political and social conditions. Utilizing historical, social scientific and health literature, timelines of health and history for five countries (Cambodia, Myanmar, Mongolia, North Korea and Timor Leste) are mapped over a 30-50 year period. The case studies compare and contrast key turning points in political and health policy history, and examines the manner in which these turning points sets the scene for the acting out of longer term health policy formation, particularly with regard to the managerial domains of health policy making. Findings illustrate that the direction of health policy reform is shaped by the character of political reform, with countries in the region being at variable stages of transition from monolithic and centralized administrations, towards more complex management arrangements characterized by a diversity of health providers, constituency interest and financing sources. The pace of reform is driven by a country's institutional capability to withstand and manage transition shocks of post conflict rehabilitation and emergence of liberal economic reforms in an altered governance context. These findings demonstrate that health policy analysis needs to be informed by a deeper understanding and questioning of the historical trajectory and political stance that sets the stage for the acting out of health policy formation, in order that health systems function optimally along their own historical pathways.

Financial cooperatives and the development of social capital.

 Financial Cooperatives and the Development of Social Capital thesis examines the generation of social capital within locally owned and managed financial cooperatives and their communities in Cambodia, Timor Leste and the Solomon Islands and contrasts factors which affect the development of social capital and the associated impacts on the institution.

The political economy of cross-border relations : the TNI and East Timor

Within a framework of formally increasingly cordial bilateral relations, the Indonesian military, the TNI, was engaging in and allowing extensive cross-border trade and smuggling while pursuing a policy of limited cross-border destabilization of East Timor. This seemingly contradictory policy, run from the TNI's 'strategic command centre' in Atambua, West Timor, met the TNI's continuing need to fund its own activities (and those of its proxies) through both legal and illegal means, to provide leverage for the coming talks about the formal demarcation of the border, and to provide a foothold to longer-term irredentist claims to the former occupied province and now independent state.

The Permian of Timor : stratigraphy, palaeontology and palaeography

The Permian of Timor in the Lesser Sunda Islands has attracted the attention of palaeontologists since the middle of the nineteenth century because of the richness, diversity and excellent state of preservation of its fauna. These abundant fossil data have been compiled and updated for the present account. The Permian rocks of Timor were deposited on the northern margin of Australia. At the present time the northern margin of Australia, in the region of Timor, is involved in a continent–arc collision, where Australia is colliding with the Banda Arcs. As a result of this collision, Permian rocks of the Australian margin have been disrupted by folding and faulting with the generation of mud-matrix mélange, and uplifted to form part of the island of Timor. Due to this tectonic disruption, it has proved difficult to establish a reliable stratigraphy for the Permian units on Timor, especially as the classic fossil collections were obtained largely from the mélange or purchased from the local people, and do not have adequate stratigraphic control. Detailed systematic, structural, stratigraphic and sedimentological studies since the 1960s have provided a firmer stratigraphic and palaeogeographic background for reconsideration of the significance of the classic fossil collections. Permian rocks on Timor belong either to a volcanic-carbonate sequence (Maubisse Formation), or to a clastic sequence (Atahoc and Cribas formations) in which volcanics are less prominent. The Permian sequences were deposited on Australian continental basement which was undergoing extension with spasmodic volcanic activity. Carbonates of the Maubisse Formation were deposited on horst blocks and volcanic edifices, while clastic sediments of the Atahoc and Cribas formations were deposited in grabens. The clastic sediments are predominantly fine-grained, derived from a distant siliciclastic source, and are interbedded with sediments derived from the volcanics and carbonates of adjacent horst blocks. Bottom conditions in the graben were often anoxic. In the present account, events on Timor during the Permian are related to the regional tectonic context, with the northward movement of Australia leading to the amelioration of the climate from sub-glacial to sub-tropical, together with the separation of crustal blocks from the northern Australian margin to form the Meso-Tethys.

East Timor : beyond independence

The chapters in this book examine the major themes of development, borders and security, politics and justice, resource and land management, education, and language policy. Though the country was initially lauded as a case study in successful state-building, the crisis of 2006 demonstrated that East Timor had more in common with other post-colonial, post-conflict societies than some of thse earlier optimistic assessments suggested. East Timor continues to attract the interest and attention of governments, scholars, development institutions and aid workers as a society rebuilding itself after almost a quarter of a century of profound trauma, and the consecutive eras of colonialism. Covering the era from the independence referendum in August 1999 to the political crisis in 2006, and future prospects and challenges, this book is an invaluable resource for understanding the challenges facing the first new nation of the 21st century.

Same blind eyes turned on Timor

Given advance notice that the street bully is about to beat up your neighbour, three courses of action are open to you. The first is to try to dissuade the bully from his violent intent. The second is to warn your neighbour so that he can make preparations to defend himself or flee. The third is to do nothing, sit back and watch the attack. Last week, Captain Andrew Plunkett claimed the Australian Government failed to act on intelligence that could have prevented the massacre of 47 civilians at a police station in Maliana in September 1999. If his claims are true, it will be the second time in 24 years that Canberra chose option three in its dealings with the people of East Timor.
