Use of serum and blood samples on filter paper to improve the surveillance of dengue in Pacific Island Countries

Background In Pacific Island Countries (PICs) the epidemiology of dengue is characterized by long-term transmission of a single dengue virus (DENV) serotype. The emergence of a new serotype in one island country often indicates major outbreaks with this serotype will follow in other PICs. Objectives Filter paper (FP) cards on which whole blood or serum from dengue suspected patients had been dried was evaluated as a method for transportation of this material by standard mail delivery throughout the Pacific. Study design Twenty-two FP-dried whole blood samples collected from patients in New Caledonia and Wallis & Futuna Islands, during DENV-1 and DENV-4 transmission, and 76 FP-dried sera collected from patients in Yap State, Majuro (Republic of Marshall Islands), Tonga and Fiji, before and during outbreaks of DENV-2 in Yap State and DENV-4 in Majuro, were tested for the presence of DENV RNA, by serotype specific RT-PCR, at the Institut Louis Malardé in French Polynesia. Results The serotype of DENV could be determined, by a variety of RT-PCR procedures, in the FP-dried samples after more than three weeks of transport at ambient temperatures. In most cases, the sequencing of the envelope gene to genotype the viruses also was possible. Conclusions The serotype and genotype of DENV can be determined from FP-dried serum or whole blood samples transported over thousands of kilometers at ambient, tropical, temperatures. This simple and low-cost approach to virus identification should be evaluated in isolated and resource poor settings for surveillance for a range of significant viral diseases.

Aboriginality and the Northern Territory intervention

Architects and supporters of the Northern Territory Emergency Response (the intervention) mobilised a range of ideas about Aboriginality to introduce and justify the policy program. These representations link Aboriginality to abuse of Aboriginal children, establishing a debate about the nature and future of Aboriginality in a context that limits the discursive authority of Aboriginal people. Aboriginality is represented as savage and in need of settler-imposed control, and also primitive and in need of development. These constructions understand Aboriginality temporally, situating it in the past but providing moral justification for coercing Indigenous people into the settler present. Aboriginality is also constructed spatially in this discourse, with prescribed communities framed as the location of both authentic Aboriginality and of threatening disorder. The intervention is framed as extending settler authority over this troubling terrain, containing and redeeming Aboriginality through inclusion in the settler nation’s moral order.

Aboriginality and the Northern Territory intervention

This thesis examines the construction of Aboriginality in recent public policy reasoning through identifying representations deployed by architects and supporters of the Commonwealth’s 2007 Northern Territory Emergency Response (the intervention). Debate about the Northern Territory intervention was explicitly situated in relation to a range of ideas about appropriate Government policy towards Indigenous people, and particularly about the nature, role, status, value and future of Aboriginality and of Aboriginal people and Torres Strait Islanders. This project involves analysis of constructions of Aboriginality deployed in texts created and circulated to explain and justify the policy program. The aim of the project is to identify the ideas about Aboriginality deployed by the intervention’s architects and supporters, and to examine the effects and implications of these discourses for political relationships between Indigenous people and settlers in Australia. This thesis will argue that advocates of the Northern Territory intervention construct Aboriginality in a range of important ways that reassert and reinforce the legitimacy of the settler colonial order and the project of Australian nationhood, and operate to limit Aboriginal claims. Specifically, it is argued that in linking Aboriginality to the abuse of Aboriginal children, the intervention’s advocates and supporters establish a political debate about the nature and future of Aboriginality within a discursive terrain in which the authority and perspectives of Indigenous people are problematised. Aboriginality is constructed in this process as both temporally and spatially separated from settler society, and in need of coercive integration into mainstream economic and political arrangements. Aboriginality is depicted by settler advocates of intervention as an anachronism, with Aboriginal people and cultures understood as primitive and/or savage precursors to settlers who are represented as modern and civilised. As such, the communities seen as the authentic home or location of Aboriginality represent a threat to Aboriginal children as well as to settlers. These constructions function to obscure the violence of the settler order, provide justification or moral rehabilitation for the colonising project, and reassert the sovereignty of the settler state. The resolution offered by the intervention’s advocates is a performance or enactment of settler sovereignty, representing a claim over and through both the territory of Aboriginal people and the discursive terrain of nationhood.

Past 140-year environmental record in the northern South China Sea : evidence from coral skeletal trace metal variations

About 140-year changes in the trace metals in Porites coral samples from two locations in the northern South China Sea were investigated. Results of PCA analyses suggest that near the coast, terrestrial input impacted behavior of trace metals by 28.4%, impact of Sea Surface Temperature (SST) was 19.0%, contribution of war and infrastructure were 14.4% and 15.6% respectively. But for a location in the open sea, contribution of War and SST reached 33.2% and 16.5%, while activities of infrastructure and guano exploration reached 13.2% and 14.7%. While the spatiotemporal change model of Cu, Cd and Pb in seawater of the north area of South China Sea during 1986–1997 were reconstructed. It was found that in the sea area Cu and Cd contaminations were distributed near the coast while areas around Sanya, Hainan had high Pb levels because of the well-developed tourism related activities.

Aboriginal dietary intake and a successful nutrition intervention project in a Northern Territory community

This paper summarises the development and testing of the 'store-turnover' method, a non-invasive dietary survey methodology for quantitative measurement of food and nutrient intake in remote, centralised Aboriginal communities. It then describes the use of the method in planning, implementation and evaluation of a community-based nutrition intervention project in a small Aboriginal community in the Northern Territory. During this project marked improvements in both the dietary intake of the community and biological indicators of nutritional health (including vitamin status and the degree and prevalence of several risk factors for non-communicable disease) were measured in the community over a 12-month period following the development of intervention strategies with the community. Although these specific strategies are presented, emphasis is directed towards the process involved, particularly the evaluation procedures used to monitor all stages of the project with the community.

Diabetes, hyperinsulinemia, and hyperlipidemia in small aboriginal community in northern Australia

A small rural Aboriginal community in northern Australia was surveyed for diabetes, impaired glucose tolerance (IGT), hyperinsulinemia, and lipid levels. Of the 122 adults >17 yr of age who participated (95% response rate), 11.5% had diabetes, 7.4% had IGT, and the remaining 81.1% had normal glucose tolerance. Both diabetes and IGT were strongly age related. This high frequency of diabetes occurred, despite the population being relatively lean. Although the body mass index (BMI) increased with age in both men and women, only 25% of the population overall had BMI >25 kg/m2. There were wide ranges of insulin responses to glucose, with the upper fertile of 2-h insulin levels being more than seven times higher than the lower fertile (144 ± 13 vs. 19 ± 1 mLI/L). Hyperinsulinemia was associated with IGT, elevated triglycerides, and lower high-density lipoprotein cholesterol levels. Lipid abnormalities were much more frequent among men than women. Cholesterol levels were an average of 0.55 mM higher and triglycerides an average of 1.05 mM higher in men than in women, and both increased with age. In conclusion, this small isolated Aboriginal population from northern Australia had an unexpectedly high frequency of diabetes (in view of their relative leanness) in association with a high frequency of metabolic abnormalities indicative of insulin resistance (hyperinsulinemia, IGT, hypertriglyceridemia).

Retooling Asian-Pacific teachers to promote creativity, innovation and problem solving in science classrooms

This paper reports on a Professional Learning Programme undertaken by primary school teachers in China that aimed to facilitate the development of ‘adaptive expertise’ in using technology to facilitate innovative science teaching and learning such as that envisaged by the Chinese Ministry of Education’s (2010–2020) education reforms. The study found that the participants made substantial progress towards the development of adaptive expertise manifested not only by advances in the participants’ repertoires of pedagogical content knowledge but also in changes to their levels of confidence and identities as teachers. By the end of the programme, the participants had coalesced into a professional learning community that readily engaged in the sharing, peer review, reuse and adaption, and collaborative design of innovative science learning and assessment activities. The findings from the study indicate that those engaged in the development of Professional Learning Programmes in Asia-Pacific nations need to take cognizance of certain cultural factors and traditions idiosyncratic to the educational systems. This is reflected in the amended set of principles to inform the design and implementation of professional learning programmes presented in the concluding sections of the paper.

Examining the impact of climate change on dengue transmission in the Asia-Pacific region

Dengue fever (DF) is a serious public health concern in many parts of the world. An increase in DF incidence has been observed globally over the past decades. Multiple factors including urbanisation, increased international travels and global climate change are thought to be responsible for increased DF. However, little research has been conducted in the Asia-Pacific region about the impact of these changes on dengue transmission. The overarching aim of this thesis is to explore the spatiotemporal pattern of DF transmission in the Asia-Pacific region and project the future risk of DF attributable to climate change. Annual data of DF outbreaks for sixteen countries in the Asia-Pacific region over the last fifty years were used in this study. The results show that the geographic range of DF in this region increased significantly over the study period. Thailand, Vietnam and Laos were identified as the highest risk areas and there was a southward expansion observed in the transmission pattern of DF which might have originated from Philippines or Thailand. Additionally, the detailed DF data were obtained and the space-time clustering of DF transmission was examined in Bangladesh. Monthly DF data were used for the entire country at the district level during 2000-2009. Dhaka district was identified as the most likely DF cluster in Bangladesh and several districts of the southern part of Bangladesh were identified as secondary clusters in the years 2000-2002. In order to examine the association between meteorological factors and DF transmission and to project the future risk of DF using different climate change scenarios, the climate-DF relationship was examined in Dhaka, Bangladesh. The results show that climate variability (particularly maximum temperature and relative humidity) was positively associated with DF transmission in Dhaka. The effects of climate variability were observed at a lag of four months which might help to potentially control and prevent DF outbreaks through effective vector management and community education. Based on the quantitative assessment of the climate-DF relationship, projected climate change will likely increase mosquito abundance and activity and DF in this area. Assuming a temperature increase of 3.3oC without any adaptation measures and significant changes in socio-economic conditions, the consequence will be devastating, with a projected annual increase of 16,030 cases in Dhaka, Bangladesh by the end of this century. Therefore, public health authorities need to be prepared for likely increase of DF transmission in this region. This study adds to the literature on the recent trends of DF and impacts of climate change on DF transmission. These findings may have significant public health implications for the control and prevention of DF, particularly in the Asia- Pacific region.

Shifting Powers : Protection of Refugees and Displaced Persons in the Asia Pacific Region

The United Nations High Commissioner for Refugees' (UNHCR) 2011 statistics on refugee populations residing by region are a stark reminder of the challenge facing states and civil society in the Asia Pacific. In 2011, Africa hosted 2,149,000 refugees; the Americas, Europe, and Middle East and North Africa hosted 513 ,500, 1,605,500 and 1,889,900 respectively, while the Asia Pacific hosted a staggering 3,793,900. The fact that 35 per cent of the world's refugees reside in the Asia Pacific, coupled with the fact that 84 per cent of refugees displaced in Asia remain in the region,raises the questions why so few countries in the region are signatories to the Convention relating to the Status of Refugees ('Refugee Convention') or cognate rights instruments and why no formally binding regional agreement exists for the equitable sharing of responsibilities for refugees...

Volcanic architecture and chemostratigraphy within the Kalkarindji Continental Flood Basalt Province, Northern Territory : implications for eruption style from multiple fissure eruptions

This thesis was the first to define individual lava flow chemical variation and a detailed definition of the Kalkarindji Continental Flood Basalt Province, a lesser known province of the Phanerozoic eon. This thesis conducted an intensive field study that yielded numerous samples for petrography and chemical analyses as well as the generation of a detailed map of a portion of the Kalkarindji province.

Indigenous cultural values and journalism in the Asia-Pacific region : a brief history of Māori journalism

A number of scholars in the Asia-Pacific region have in recent years pointed to the importance that cultural values play in influencing journalistic practices. The Asian values debate was followed up with empirical studies showing actual differences in news content when comparing Asian and Western journalism. At the same time, such studies have focused on national cultures only. This paper instead examines the issue against the background of an Indigenous culture in the Asia-Pacific region. It explores the way in which cultural values may have played a role in the journalistic practice of Māori journalists in Aotearoa New Zealand over the past nearly 200 years and finds numerous examples that demonstrate the significance of taking cultural values into account. The paper argues that the role played by cultural values is important to examine further, particularly in relation to journalistic practices amongst sub-national news cultures across the Asia-Pacific region.
