    The results of the joint research of Spanish and Argentinean teams since 1986 on shell middens of Tierra del Fuego can be useful guidelines for excavating and explaining similar archaeological sites around the world. We assume that human activity is organized in space and time and, as a consequence the random, non-random or homogeneous structure the resulting archaeological evidence has to be demonstrated before assuming a palimpsest nature of the deposit. We show the possibilities and releva...

    Numerous large and small shell middens have been reported throughout the world. An interesting question is when the huge and thick shell middens were formed, and how many years were required to build up the whole midden. Shell middens contain not only shell fragments but also organic substances such as bones, nuts, acorn, and plant residues, which are suitable substances with which to establish {sup 14}C chronology of the middens. We have conducted {sup 14}C dating on terrestrial and marine materials collected from two lowland shell middens, the Higashimyo site in Japan (the Earliest Jomon period) and the Kimhae site in Korea (the Proto-Three Kingdom period), to establish high precision {sup 14}C chronologies and determine the time required for shell accumulation. According to Bayesian analysis of {sup 14}C ages from terrestrial samples, accumulation of Midden No. 1 at Higashimyo (altitude from -1.1 to -2.3 m a.s.l., {Delta}d = 1.2 m) started at around 8050-7950 cal BP and ended at 7950-7750 cal BP, lasting for ca. 100 cal yr, while accumulation of Midden No. 2 (altitude from -0.5 to -2.0 m a.s.l., {Delta}d = 1.5 m) started at around 8050-7800 cal BP and ended at 7800-7650 cal BP, lasting for ca. 200 cal yr. Thus the Midden No. 1 was abandoned a bit earlier than Midden No. 2, but the time range for sediment accumulation overlaps each other. Accumulation at the Kimhae shell midden (altitude from 5 to 14 m a.s.l., {Delta}d = 9 m) started at around the middle of the 1st C cal BC and ended at around the middle of the 3rd C cal AD, lasting for ca. 250 to 300 cal yr.

    Full Text Available Several shell middens of coastal Sri Lanka indicate human occupation in the mid-Holocene and are recognized as being of prime importance in the archaeological narrative of the island. A salvage archaeology operation conducted at the Mini-athiliya shell midden in the Southern Province of Sri Lanka, yielded ancient human remains associated with stone implements and culturally modified faunal remains. The main objective of this rescue operation was to mitigate the destruction to this archaeological site. We report the excavation strategy and dating of this mid-Holocene shell midden, while focusing on the discovery and extraction of a complete human burial that had not been disturbed by the shell mining activity at the site. This excavation is intended to serve as a precursor to systematic investigation of the coastal shell middens of southern Sri Lanka.

  4. Early and middle holocene hunter-gatherer occupations in western Amazonia: the hidden shell middens.

    Directory of Open Access Journals (Sweden)

    Umberto Lombardo

    Full Text Available We report on previously unknown early archaeological sites in the Bolivian lowlands, demonstrating for the first time early and middle Holocene human presence in western Amazonia. Multidisciplinary research in forest islands situated in seasonally-inundated savannahs has revealed stratified shell middens produced by human foragers as early as 10,000 years ago, making them the oldest archaeological sites in the region. The absence of stone resources and partial burial by recent alluvial sediments has meant that these kinds of deposits have, until now, remained unidentified. We conducted core sampling, archaeological excavations and an interdisciplinary study of the stratigraphy and recovered materials from three shell midden mounds. Based on multiple lines of evidence, including radiocarbon dating, sedimentary proxies (elements, steroids and black carbon, micromorphology and faunal analysis, we demonstrate the anthropogenic origin and antiquity of these sites. In a tropical and geomorphologically active landscape often considered challenging both for early human occupation and for the preservation of hunter-gatherer sites, the newly discovered shell middens provide evidence for early to middle Holocene occupation and illustrate the potential for identifying and interpreting early open-air archaeological sites in western Amazonia. The existence of early hunter-gatherer sites in the Bolivian lowlands sheds new light on the region's past and offers a new context within which the late Holocene "Earthmovers" of the Llanos de Moxos could have emerged.

  5. Impact of prehistoric cooking practices on paleoenvironmental proxies in shell midden constituents

    Paleoenvironmental proxy records such as oxygen isotopes of calcareous skeletal structures like fish otoliths or mollusk shells provide highest-resolution information about environmental conditions experienced by the organism. Accumulations of such skeletal structures by ancient coastal populations in so called "shell midden" deposits provide us with sub-seasonally resolved paleoclimate records covering time spans up to several millennia. Given their high temporal resolution, these deposits are increasingly used for paleoclimate reconstructions and complement our understanding of ancient climate changes. However, gathered as comestibles, most of these skeletal remains were subject to prehistoric cooking methods prior to deposition. The associated alteration of the chemical proxy signatures as well as the subsequent error for paleoenvironmental reconstructions remained almost entirely neglected so far. Here, we present clumped isotope, conventional oxygen and carbon isotopes as well as element:Ca ratios measured in modern bivalve shells after exposing them to different prehistoric cooking methods. Our data show that most cooking methods considerably alter commonly used paleoclimate proxy systems which can lead to substantial misinterpretations of ancient climate conditions. Since the magnitude of chemical alteration is not distinguishable from natural temperature variability in most coastal settings, the alteration of shell midden constituents by prehistoric cooking remains likely unnoticed in most cases. Thus, depending on the cooking method, pre-depositional heating might have introduced considerable errors into previous paleoclimate studies. However, our data also show that clumped isotope thermometry represents a suitable diagnostic tool to detect such pre-depositional cooking events and also allows differentiating between the most commonly applied prehistoric cooking methods.

    Full Text Available In prehistoric times, innumerous shell middens, called "sambaquis", consisting mainly of remains of marine organisms, were built along the Brazilian coast. Although the scientific community took interest in these anthropic formations, especially since the nineteenth century, their pedological context is still poorly understood. The purpose of this study was to characterize and identify the physical and chemical changes induced by soil-forming processes, as well as to compare the morphology of shell midden soils with other, already described, anthropogenic soils of Brazil. Four soil profiles developed from shell middens in the Região dos Lagos - RJ were morphologically described and the physical and chemical properties determined. The chemical analysis showed that Ca, Mn, Mg, and particularly P and Zn are indicators of anthropic horizons of midden soils, as in the Amazon Dark Earths (Terras Pretas de Índio. After the deposition of P-rich material, P reaction and leaching can mask or disturb the evidence of in situ man-made strata, but mineralogical and chemical studies of phosphate forms can elucidate the apparent complexity. Lower phosphate-rich strata without direct anthropic inputs indicate P leaching and precipitation in secondary forms. The total and bioavailable contents of Ca, Mg, Zn, Mn, Cu, P, and organic C of midden soils were much higher than of regional soils without influence of ancient human settlements, demonstrating that the high fertility persisted for long periods, at some sites for more than 4000 years. The physical analysis showed that wind-blown sand contributed significantly to increase the sand fraction in the analyzed soils (texture classes sand, sandy loam and sandy clay loam and that the aeolian sand accumulation occurred simultaneously with the midden formation.

    There are still many archaeological contexts where soil micromorphology has been little applied. Examples of such are anthropic shell deposits, common in coastal settings worldwide. These archaeological sites have complex stratigraphies composed mainly of shell from diverse species of local mollusks and gastropods. They have the peculiarity of being highly porous sediments with a coarse fraction that is dominated by gravel-sized bioclastic remains (shell, fish bones) and a fine fraction composed of organic material (charcoal, organic matter). The use of soil micromorphology in shell deposits was started by the Spanish-Argentinean research team working in Tierra del Fuego (Argentina) since 1986. This project focused on excavation of hunter-gatherer sites from the contact period. One of the main objectives was to develop a detailed excavation method for shell middens that maximized the amount of recorded data during archaeological excavation. In this perspective, microstratigraphy was conceived as a fundamental complement for the study of site formation processes, as it would provide with high definition data for identification of shell accumulation episodes, trampling on site, abandonment periods, taphonomic alterations etc. A reference collection of known environmental and anthropic control features, such as hearths, trampling areas, wood ashes from local species, among others, was built to help in the microscopic characterization of archaeological samples. In this work, we analyze this experimental collection and compare it with samples from the Tunel VII archaeological site, located in the northern coast of the Beagle Channel and dated from the 18th-19th centuries. The set of modern samples included: trampling area from an animal pathway; beach deposit; forest litter; soil under the forest; hearths lit in diverse contexts (on the prairie, the beach and from the archaeologist camp site); and experimental burnt valves of Mytilus edulis, the main malacological

  9. Shellfish, seasonality, and sedentism : δ18O analysis of California mussels from early Holocene shell middens on San Miguel Island, California

    International Nuclear Information System (INIS)

    We estimate seasonality of shellfish harvest and site occupation for four Early Holocene shell middens on California's San Miguel Island using a dataset of 449 δ18O measurements from 84 mussel shells (Mytilus californianus). Seasonality was assigned to prehistoric mussels using paleo sea-surface temperature (PSST) estimates from isotopic data obtained across full shell profiles. The results suggest that PSSTs around San Miguel Island were generally cooler between ∼10,000-8600 calBP and that mussels were harvested in a range of water temperatures which suggest a mix of seasonal and year round harvesting at the four sites. Two substantial shell middens dated to ∼10,000 and ∼9000 calBP appear to have been residential basecamps where Paleocoastal peoples harvested shellfish during all four seasons. These data suggest that Early Holocene peoples occupied the Channel Islands year round and highlight the importance of stable isotope analysis of marine shells for helping evaluate human settlement and subsistence strategies along the Pacific Coast.

    The relationship between Syncrude Canada Ltd., and the aboriginal people of Northeast Alberta was discussed. In 1970, Syncrude began development of its oil sands mega-project in the Fort McMurray region. Since then, the company has worked in partnership with the aboriginal communities to maximize their productive participation in the oil sands. Syncrude has provided opportunities in employment, education, and business and community development. Their goals for aboriginal employment are: (1) to attain 10 per cent aboriginal employees in the Company's direct workforce, and (2) to attain 13 per cent aboriginal employees in the overall workforce, including contractors. Currently, Syncrude Canada employs 315 aboriginal people in various career positions. The Company is also committed to the protection of the environment. As proof of this commitment, when a mine site is reclaimed, the Company does all that is required to ensure that the land can support both industry and traditional land uses such as hunting, fishing and trapping. Syncrude also works on air quality issues dealing with odors and sulfur dioxide emissions as shown by a two million dollar company-sponsored program to examine local air quality and its effect on people and their health. figs

  17. Tuberculosis in Aboriginal Canadians

    Vernon H Hoeppner

    2000-01-01

    Full Text Available Endemic tuberculosis (TB was almost certainly present in Canadian aboriginal people (aboriginal Canadians denotes status Indians, Inuit, nonstatus Indians and metis as reported by Statistics Canada before the Old World traders arrived. However, the social changes that resulted from contact with these traders created the conditions that converted endemic TB into epidemic TB. The incidence of TB varied inversely with the time interval from this cultural collision, which began on the east coast in the 16th century and ended in the Northern Territories in the 20th century. This relatively recent epidemic explains why the disease is more frequent in aboriginal children than in Canadian-born nonaboriginal people. Treatment plans must account for the socioeconomic conditions and cultural characteristics of the aboriginal people, especially healing models and language. Prevention includes bacillus Calmette-Guerin vaccination and chemoprophylaxis, and must account for community conditions, such as rates of suicide, which have exceeded the rate of TB. The control of TB requires a centralized program with specifically directed funding. It must include a program that works in partnership with aboriginal communities.

    Transient celestial phenomena feature prominently in the astronomical knowledge and traditions of Aboriginal Australians. In this paper, I collect accounts of the Aurora Australis from the literature regarding Aboriginal culture. Using previous studies of meteors, eclipses, and comets in Aboriginal traditions, I anticipate that the physical properties of aurora, such as their generally red colour as seen from southern Australia, will be associated with fire, death, blood, and evil spirits. The survey reveals this to be the case and also explores historical auroral events in Aboriginal cultures, aurorae in rock art, and briefly compares Aboriginal auroral traditions with other global indigenous groups, including the Maori of New Zealand.

    The traditional cultures of Aboriginal Australians include a significant astronomical component, perpetuated through oral tradition, ceremony, and art. This astronomical component includes a deep understanding of the motion of objects in the sky, and this knowledge was used for practical purposes, such as constructing calendars. There is also evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, paid careful attention to unexpected phenomena such as eclipses and meteorite impacts, and could determine the cardinal points to an accuracy of a few degrees.

    The study of arid palaeoenvironments is often frustrated by the poor or non-existent preservation of plant and animal material, yet these environments are of considerable environmental importance. The analysis of pollen and macrofossils isolated from herbivore middens has been an invaluable source of information regarding past environments and the nature of ecological fluctuations within arid zones. The application of ancient DNA (aDNA) techniques to hot, arid zone middens remains unexplored. This paper attempts to retrieve and characterise aDNA from four Southern Hemisphere fossil middens; three located in hot, arid regions of Australia and one sample from South Africa's Western Cape province. The middens are dated to between 30,490 (±380) and 710 (±70) cal yr BP. The Brockman Ridge midden in this study is potentially the oldest sample from which aDNA has been successfully extracted in Australia. The application of high-throughput sequencing approaches to profile the biotic remains preserved in midden material has not been attempted to date and this study clearly demonstrates the potential of such a methodology. In addition to the taxa previously detected via macrofossil and palynological analyses, aDNA analysis identified unreported plant and animal taxa, some of which are locally extinct or endemic. The survival and preservation of DNA in hot, arid environments is a complex and poorly understood process that is both sporadic and rare, but the survival of DNA through desiccation may be important. Herbivore middens now present an important source of material for DNA metabarcoding studies of hot, arid palaeoenvironments and can potentially be used to analyse middens in these environments throughout Australia, Africa, the Americas and the Middle East.

  2. Packrat middens from Canyon de Chelly, northeastern Arizona: Paleoecological and archaeological implications

    Betancourt, Julio L.; Davis, Owen K.

    1984-01-01

    In western North America, pollen data from highland lakes are often used to reconstruct vegetation on the adjacent lowlands. Plant macrofossils and pollen from packrat middens now provide a means to evaluate such reconstructions. On the basis of pollen diagrams from the Chuska Mountains, H. E. Wright, Jr., A. M. Bent, B. S. Hansen, and L. J. Maher, Jr., ((1973), Geological Society of America Bulletin, 84, 1155-1180) arrived at conservative estimates for late Pleistocene depression of highland conifers. In their interpretation, a proposed slight depression of 500 m for lower tree line precluded expansion of Pinus ponderosa into elevations now in desertscrub. Instead, it was suggested that pinyon pine and Artemisia occupied the lowland plateaus. Packrat midden records on either side of the Chuskas fail to verify this model. Early Holocene middens from Chaco Canyon, New Mexico, and a terminal Pleistocene midden from Canyon de Chelly, Arizona, show that blue spruce, limber pine, Douglas fir, dwarf juniper, and Rocky Mountain juniper expanded at least down to 1770 m elevation Neither Colorado pinyon nor ponderosa pine was found as macrofossils in the middens. Artemisia pollen percentages are high in the terminal Pleistocene midden, as they are in the Chuska Mountain pollen sequence, suggesting regional dominance by sagebrush steppe. Of 38 taxa identified, only 3 are shared by middens dated 11,900 and 3120 yr B.P. from Canyon de Chelly, indicating a nearly complete turnover in the flora between the late Pleistocene and late Holocene. Although corn was previously thought to have been introduced to the Colorado plateaus after 2200 yr B.P., the midden dated 3120 yr B.P. contains pollen of corn and other indicators of incipient agriculture.

    2010-06-01

    We present a comprehensive analysis of Australian Aboriginal accounts of meteors. The data used were taken from anthropological and ethnographic literature describing oral traditions, ceremonies, and Dreamings of 97 Aboriginal groups representing all states of modern Australia. This revealed common themes in the way meteors were viewed between Aboriginal groups, focusing on supernatural events, death, omens, and war. The presence of such themes around Australia was probably due to the unpredictable nature of meteors in an otherwise well-ordered cosmos.

  6. Rodent middens, a new method for Quaternary research in arid zones of South America

    Science.gov (United States)

    Betancourt, J.L.; Saavedra, B.

    2002-01-01

    In arid and semi-arid regions of South America, historical evidence for climate and vegetation change is scarce despite its importance for determining reference conditions and rates of natural variability in areas susceptible to modern desertification. Normal lines of evidence, such as pollen stratigraphies from lakes, are either rare or unobtainable in deserts; studies of late Quaternary vegetation history are few and generally inconclusive. This gap in knowledge may be corrected with discovery and development of fossil rodent middens in rocky environments throughout arid South America. These middens, mostly the work of Lagidium, Phyllotis, Abrocoma and Octodontomys, are rich in readily identifiable plant macrofossils, cuticles and pollen, as well as vertebrate and insect remains. In the North American deserts, more than 2,500 woodrat (Neotoma) middens analyzed since 1960 have yielded a detailed history of environmental change during the past 40,000 years. Preliminary work in the pre-puna, Monte and Patagonian Deserts of western Argentina, the Atacama Desert of northern Chile/southern Peru, the Mediterranean matorral of central Chile, and the Puna of the Andean altiplano suggest a similar potential for rodent middens in South America. Here we borrow from the North American experience to synthesize methodologies and approaches, summarize preliminary work, and explore the potential of rodent midden research in South America.

  7. Eclipses in Australian Aboriginal Astronomy

    2011-01-01

    We explore 50 Australian Aboriginal accounts of lunar and solar eclipses to determine how Aboriginal groups understood this phenomenon. We summarise the literature on Aboriginal references to eclipses, showing that many Aboriginal groups viewed eclipses negatively, frequently associating them with bad omens, evil magic, disease, blood and death. In many communities, Elders or medicine men were believed to have the ability to control or avert eclipses by magical means, solidifying their role as provider and protector within the community. We also show that many Aboriginal groups understood the motions of the sun-earth-moon system, the connection between the lunar phases and tides, and acknowledged that solar eclipses were caused by the moon blocking the sun.

    Garvey, G; Towney, P; McPhee, J R; Little, M; Kerridge, I H

    2004-12-01

    It is well recognised that medicine manifests social and cultural values and that the institution of healthcare cannot be structurally disengaged from the sociopolitical processes that create such values. As with many other indigenous peoples, Aboriginal Australians have a lower heath status than the rest of the community and frequently experience the effects of prejudice and racism in many aspects of their lives. In this paper the authors highlight values and ethical convictions that may be held by Aboriginal peoples in order to explore how health practitioners can engage Aboriginal patients in a manner that is more appropriate. In doing so the authors consider how the ethics, values, and beliefs of the dominant white Australian culture have framed the treatment and delivery of services that Aboriginal people receive, and whether sufficient effort has been made to understand or acknowledge the different ethical predispositions that form the traditions and identity of Aboriginal Australia(ns).

    2011-01-01

    Remains from Paleo-Eskimo cultures are well-documented, but complete preservation is rare. Two kitchen middens in Greenland are known to hold extremely well-preserved organic artefacts. Here, we assess the fate of the Qajaa site in Western Greenland under future climate conditions based on site...... characteristics measured in situ and from permafrost cores. Measurements of thermal properties, heat generation, oxygen consumption and CO2 production show that the kitchen midden can be characterized as peat but produces 4–7 times more heat than natural sediment. An analytical model from permafrost research has...... been applied to assess future thawing of the midden. Results show that the preservation conditions are controlled by freezing temperatures and a high water/ice content limiting the subsurface oxygen availability. Threats to the future preservation are related to thawing followed by drainage...

  10. Comets in Australian Aboriginal Astronomy

    We present 25 accounts of comets from 40 Australian Aboriginal communities, citing both supernatural perceptions of comets and historical accounts of bright comets. Historical and ethnographic descriptions include the Great Comets of 1843, 1861, 1901, 1910, and 1927. We describe the perceptions of comets in Aboriginal societies and show that they are typically associated with fear, death, omens, malevolent spirits, and evil magic, consistent with many cultures around the world. We also provide a list of words for comets in 16 different Aboriginal languages.

  14. Aboriginal Agency and Marginalisation in Australian Society

    Directory of Open Access Journals (Sweden)

    Terry Moore

    2014-09-01

    Full Text Available It is often argued that while state rhetoric may be inclusionary, policies and practices may be exclusionary. This can imply that the power to include rests only with the state. In some ways, the implication is valid in respect of Aboriginal Australians. For instance, the Australian state has gained control of Aboriginal inclusion via a singular, bounded category and Aboriginal ideal type. However, the implication is also limited in their respect. Aborigines are abject but also agents in their relationship with the wider society. Their politics contributes to the construction of the very category and type that governs them, and presses individuals to resist state inclusionary efforts. Aboriginal political elites police the performance of an Aboriginality dominated by notions of difference and resistance. The combined processes of governance act to deny Aborigines the potential of being both Aboriginal and Australian, being different and belonging. They maintain Aborigines’ marginality.

  17. Wind power projects and Aboriginal consultation

    Energy Technology Data Exchange (ETDEWEB)

    Isaac, T. [McCarthy Tetrault LLP, Vancouver, BC (Canada)

    2006-07-01

    This presentation outlined some of the legal aspects related to Aboriginal involvement in wind power development consultation processes and disputes. Aboriginal rights are rights held by Aboriginal people that are an element of a practice, custom, or tradition integral to the culture of groups claiming such rights. Wind power developers should understand that Aboriginal rights claims may include fishing; whaling; transportation; and cultural and spiritual activities. Aboriginal title is a subcategory of Aboriginal rights, and is a right to land itself, and an encumbrance on the Crown's underlying title to land. Weak Aboriginal claims where potential infringement by energy developers is minor may only require notice and information. Strong prima facie cases for Aboriginal rights and title where the potential for infringement is of high significance may result in more extensive consultation involving interim solutions; formal Aboriginal participation in decision-making processes; and written responses demonstrating how Aboriginal concerns have been considered. There are a number of circumstances requiring a case-by-case approach, and the Crown may make decisions in the face of Aboriginal disagreement. However, energy developers should ensure that consultation processes are fair and reasonable. Conflicting interests can often be successfully resolved through consultation, and accommodation to Aboriginal rights may include mitigation, avoiding interference, and agreeing to as little infringement as possible. Aboriginal title may attach to private land but only to the Crown's underlying title. The Crown has no duty to consult respecting Aboriginal title on private land because title has already been infringed. In these cases, duty to consult and accommodate may be discharged through other regulatory processes such as environmental impact assessments. It was concluded that wind power project proponents should build a relationship with the Crown, as avoiding

  18. ABORIGINALITY AND TOURISM

    Maximiliano E. Korstanje

    2013-06-01

    Full Text Available Cultural tourism seems to be a buzz-word applied on a widest contexts and studies. The importance West has given to this term is linked to a new process of acceptance of diversity as never before. However, in the core of this discourse, the spirit of colonialism remains. In this conceptual paper, not only the main assumptions of cultural tourism are discussed in depth, but also its connection with colonization. One of main problems of cultural tourism is the conceptual basis on where this theory lies. For one hand, this term is strictly applied on local communities (aboriginals or ethnic minorities that have not sustained the progress on their own. On another one, this type of new paternalism closes the door for a real opportunity of dialogue between centre and periphery. As things being, cultural tourism not only is a concept very hard to be applied on research but also follow to nourish the ethnocentrism of nineteen-century racism.

  19. Plant Functional Variability in Response to Late-Quaternary Climate Change Recorded in Ancient Packrat Middens

    Science.gov (United States)

    Holmgren, C. A.; Potts, D. L.

    2006-12-01

    Responses of plant functional traits to environmental variability are of enduring interest because they constrain organism performance and ecosystem function. However, most inferences regarding plant functional trait response to climatic variability have been limited to the modern period. To better understand plant functional response to long-term climate variability and how adjustments in leaf morphology may contribute to patterns of species establishment, persistence, or extirpation, we measured specific leaf area (SLA) from macrofossils preserved in ancient packrat middens collected along the Arizona/New Mexico border, USA. Our record spanned more than 32,000 years and included six woodland and Chihuahuan Desert species: Berberis cf. haematocarpa, Juniperus cf. coahuilensis, Juniperus osteosperma, Larrea tridentata, Prosopis glandulosa and Parthenium incanum. We predicted that regional climatic warming and drying since the late Pleistocene would result in intraspecific decreases in SLA. As predicted, SLA was positively correlated with midden age for three of the six species (L. tridentata, J. osteosperma, B. cf. haematocarpa). SLA was also negatively correlated with December (L. tridentata, J. cf. coahuilensis) or June (B. cf. haematocarpa, J. osteosperma) insolation. A unique record of vegetation community dynamics, plant macrofossils preserved in packrat middens also represent a rich and largely untapped source of information on long-term trends in species functional response to environmental change.

  20. Australian Aboriginal Astronomy and Cosmology

    Science.gov (United States)

    Clarke, Philip A.

    Australian Aboriginal ethnoastronomical traditions were recorded from a wide variety of sources in different periods. While the corpus of mythology concerning the heavens is diverse, it is unified by beliefs of a Skyworld as land with its own topography, containing plants and animals familiar to those living below. Spirits of the dead reside alongside the Creation Ancestors as celestial bodies in the Skyworld. Aboriginal hunter-gatherers used the regular movement of constellations and planets to measure time and to indicate the season, while unexpected change in the sky was seen as an omen.

  2. Distinct modes of transmission of tuberculosis in aboriginal and non-aboriginal populations in Taiwan.

    Directory of Open Access Journals (Sweden)

    Yih-Yuan Chen

    Full Text Available Tuberculosis incidence among aborigines is significantly higher than for Han Chinese in Taiwan, but the extent to which Mycobacterium tuberculosis (MTB strain characteristics contribute to this difference is not well understood. MTB isolates from aborigines and Han Chinese living in eastern and southern Taiwan, the major regions of aborigines, were analyzed by spoligotyping and 24-loci MIRU-VNTR. In eastern Taiwan, 60% of aboriginal patients were ≤20 years old, significantly younger than the non-aboriginal patients there; aborigines were more likely to have clustered MTB isolates than Han Chinese (odds ratio (OR = 5.98, p<0.0001. MTB lineages with high clustering were EAI (54.9% among southern people, and Beijing (62.5% and Haarlem (52.9% among eastern aborigines. Resistance to first-line drugs and multidrug resistance (MDR were significantly higher among eastern aborigines (≥15% than in any other geographic and ethnic group (p<0.05; MDR was detected in 5 of 28 eastern aboriginal patients ≤20 years old. Among patients from the eastern region, clustered strains (p = 0.01 and aboriginal ethnicity (p = 0.04 were independent risk factors for MDR. The lifestyles of aborigines in eastern Taiwan may explain why the percentage of infected aborigines is much higher than for their Han Chinese counterparts. The significantly higher percentage of the MDR-MTB strains in the aboriginal population warrants close attention to control policy and vaccination strategy.

    2006-07-01

    The opportunities for building relationships between Aboriginal communities and the mining industry were discussed, along with opportunities for communities to build capacity and to participate in the mining cycle. With nearly 1200 Aboriginal communities located within 200 km of minerals and metals activities in Canada, there is potential for significant economic and business growth in the communities. This educational tool informs Aboriginal communities across Canada about all the stages of the mining cycle, from early exploration to mine closure. Its purpose is to help Aboriginal people to better understand mining activities and identify the many opportunities that mining can bring to their communities. The information kit contains 4 modules corresponding to the main stages of the mining cycle. It provides examples of community experiences, positive relationships, and partnerships with mining companies. It also outlines the regulatory process to ensure Aboriginal peoples are well informed of the economic, social and environmental effects, benefits and opportunities in making decisions. refs., tabs., figs.

  5. Mediating Tragedy: Facebook, Aboriginal Peoples and Suicide

    2015-11-01

    Full Text Available Some Australian Aboriginal communities experience suicide rates that are among the highest in the world. They are also, however, avid social media users—approximately 20% higher than the national average. This article presents some preliminary findings from a current national study, funded by the Australian Research Council, titled Aboriginal identity and community online: a sociological exploration of Aboriginal peoples’ use of online social media. The purpose of the study is to gain insights into how Aboriginal peoples utilise and interact on social media, and how these technologies can assist with suicide prevention strategies. It found that Aboriginal people are engaging with Facebook to both seek and offer help for issues relating to suicide and self-harm. An existing continuum of suicide prevention strategies was evident—from light emotional support to direct suicide intervention involving health services. These strategies can be leveraged to implement effective and appropriate suicide prevention programs.

  6. Reconstructing the Star Knowledge of Aboriginal Tasmanians

    2016-01-01

    The canopy of stars is a central presence in the daily and spiritual lives of Aboriginal Tasmanians. With the arrival of European colonists, Tasmanian astronomical knowledge and traditions were interrupted and dispersed. Fragments can be found scattered in the ethnographic and historical record throughout the nineteenth century. We draw from ethnohistorical documents to analyse and reconstruct Aboriginal astronomical knowledge in Tasmania. This analysis demonstrates that stars, the Milky Way, constellations, dark nebula, the Sun, Moon, meteors, and aurorae held cultural, spiritual, and subsistence significance within the Aboriginal cultures of Tasmania. We move beyond a monolithic view of Aboriginal astronomical knowledge in Tasmania, commonly portrayed in previous research, to lay the groundwork for future ethnographic and archaeological fieldwork with Aboriginal elders and communities.

  7. Decolonisation: a critical step for improving Aboriginal health.

    2006-09-01

    Aboriginal health continues to be in crisis in Australia although expenditure has increased in service provision, strategic planning, research and policy development over the last thirty years. This paper recommends that a shift must occur to make Aboriginal health improvement a reality. This shift requires the decolonising of Aboriginal health so that the experts in Aboriginal health, namely Aboriginal people, can voice and action initiatives that address their health issues. This shift is from the current western dominant approach that continues to manage Aboriginal health in its linear spectrum of illness and disease. Aboriginal people view health differently; their contexts for health issues are also diverse requiring a more holistic and informed response.

    Social capital is a valuable resource that has received little attention in the prison context. Differences in the construct and accessibility of bonding, bridging, and linking social capital exist for Aboriginal Australians in mainstream society, but were previously unexplored in prison. This study seeks to understand contextual differences of social capital for Australian Aboriginal and non-Aboriginal men in prison. Thirty male inmates participated in qualitative interviews across three New South Wales (NSW) correctional centres. Interviews were completed between November 2014 and March 2015. Experiences of bonding and linking social capital varied among Aboriginal and non-Aboriginal participants. Opportunities for bridging social capital were limited for all participants. There is greater scope for building bonding social capital among male inmates than either bridging or linking social capital. Bonding social capital, particularly among Aboriginal men in prison, should be utilised to promote health and other programs to inmates.

    Full Text Available Abstract Context There is considerable concern about the spread of HIV disease among Aboriginal peoples in British Columbia. Objective To estimate the number of Aboriginal British Columbians infected with HIV. Design and setting A population-based analysis of Aboriginal men and women in British Columbia, Canada from 1980 to 2001. Participants Epidemic curves were fit for gay and bisexual men, injection drug users, men and women aged 15 to 49 years and persons over 50 years of age. Main outcome measures HIV prevalence for the total Aboriginal population was modeled using the UNAIDS/WHO Estimation and Projection Package (EPP. Monte Carlo simulation was used to estimate potential number infected for select transmission group in 2001. Results A total of 170,025 Aboriginals resided in British Columbia in 2001, of whom 69% were 15 years and older. Of these 1,691 (range 1,479 – 1,955 men and women aged 15 years and over were living with HIV with overall prevalence ranging from 1.26% to 1.66%. The majority of the persons infected were men. Injection drug users (range 1,202 – 1,744 and gay and bisexual men (range 145, 232 contributed the greatest number of infections. Few persons infected were from low risk populations. Conclusion More than 1 in every 100 Aboriginals aged 15 years and over was living with HIV in 2001. Culturally appropriate approaches are needed to tailor effective HIV interventions to this community.

    Full Text Available Abstract Background Otitis media (OM is the most common paediatric illness for which antibiotics are prescribed. In Australian Aboriginal children OM is frequently asymptomatic and starts at a younger age, is more common and more likely to result in hearing loss than in non-Aboriginal children. Absent transient evoked otoacoustic emissions (TEOAEs may predict subsequent risk of OM. Methods 100 Aboriginal and 180 non-Aboriginal children in a semi-arid zone of Western Australia were followed regularly from birth to age 2 years. Tympanometry was conducted at routine field follow-up from age 3 months. Routine clinical examination by an ENT specialist was to be done 3 times and hearing assessment by an audiologist twice. TEOAEs were measured at ages Results At routine ENT specialist clinics, OM was detected in 55% of 184 examinations in Aboriginal children and 26% of 392 examinations in non-Aboriginal children; peak prevalence was 72% at age 5–9 months in Aboriginal children and 40% at 10–14 months in non-Aboriginal children. Moderate-severe hearing loss was present in 32% of 47 Aboriginal children and 7% of 120 non-Aboriginal children aged 12 months or more. TEOAE responses were present in 90% (46/51 of Aboriginal children and 99% (120/121 of non-Aboriginal children aged Overall prevalence of type B tympanograms at field follow-up was 50% (n = 78 in Aboriginal children and 20% (n = 95 in non-Aboriginal children. Conclusion The burden of middle ear disease is high in all children, but particularly in Aboriginal children, one-third of whom suffer from moderate-severe hearing loss. In view of the frequently silent nature of OM, every opportunity must be taken to screen for OM. Measurement of TEOAEs at age 1–2 months to identify children at risk of developing OM should be evaluated in a routine health service setting.

    Physical inactivity is the third leading cause of the burden of disease for Australian Aboriginal adults. The neighborhood environment and social support are known to influence physical activity (PA) participation. This study examined these factors in relation to achieving PA recommendations in Aboriginal and non-Aboriginal Australians. Cross-sectional data from the 2010 Social, Economic, and Environmental Factor (SEEF) Study in New South Wales, Australia were used to estimate adjusted odds ratios (OR) for Aboriginal versus non-Aboriginal participants for PA-related attributes, including achieving PA recommendations. ORs for achieving PA recommendations were estimated in both groups. Overall, 63.1% of Aboriginal (n = 314) and 65.4% of non-Aboriginal (n = 59,175) participants met PA recommendations. Odds of healthy sleep duration were lower, and receiving GP advice to be active was higher, among Aboriginal versus non-Aboriginal participants. Aboriginal respondents had higher odds of reporting that the crime rate made it unsafe to walk and that local public transport was inaccessible. They had higher odds of disagreeing they have local shops, footpaths or free/low cost recreation facilities. PA correlates were similar in both groups. The factors relating to PA were similar in Aboriginal and non-Aboriginal people. Neighborhood and social features were less PA-favorable for Aboriginal participants suggesting multiple possible avenues for increasing PA in this older population group. PMID:27419016

  15. Preliminary assessment of late quaternary vegetation and climate of southeastern Utah based on analyses of packrat middens

    International Nuclear Information System (INIS)

    Packrat midden sequences from two caves (elevations 1585 and 2195 m; 5200 and 7200 ft) southwest of the Abajo Mountains in southeast Utah record vegetation changes that are attributed to climatic changes occurring during the last 13,000 years. These data are useful in assessing potential future climates at proposed nuclear waste sites in the area. Paleoclimates are reconstructed by defining modern elevational analogs for the vegetation assemblages identified in the middens. Based on the midden record, a climate most extreme from the present occurred prior to approximately 10,000 years before present (BP), when mean annual temperature was probably 3 to 4C (5.5 to 7F) cooler than present. However, cooling could not have exceeded 5C (9F) at 1585 m (5200 ft). Accompanying mean annual precipitation is estimated to have been from 35 to 140% greater than at present, with rainfall concentrated in the winter months. Vegetational changes beginning approximately 10,000 years BP are attributed to increased summer and mean annual temperatures, a decreasing frequency of spring freezes, and a shift from winter- to summer-dominant rainfall. Greater effective moisture than present is inferred at both cave sites from approximately 8000 to 4000 years BP. Modern flora was present at both sites by about 2000 years BP

    2014-03-01

    Full Text Available Australian Aboriginal people have among the highest rates of invasive pneumococcal disease (IPD worldwide. We investigated clinical diagnosis, risk factors, comorbidities and vaccine coverage in Aboriginal and non-Aboriginal IPD cases. Using enhanced surveillance, we identified IPD cases in Western Australia, Australia, between 1997 and 2007. We calculated the proportion with risk factors and comorbidities in children (<5 years and adults (≥15 years, as well as adults living in metropolitan and non-metropolitan regions. We then calculated the proportion of cases eligible for vaccination who were vaccinated before contracting IPD. Of the 1,792 IPD cases that were reported, 355 (20% were Aboriginal and 1,155 (65% were adults. Pneumonia was the most common diagnosis (61% of non-Aboriginal and 49% of Aboriginal adult IPD cases in 2001-2007. Congenital abnormality was the most frequent comorbidity in non-Aboriginal children (11%. In Aboriginal children, preterm delivery was most common (14%. Ninety-one percent of non-Aboriginal and 96% of Aboriginal adults had one or more risk factors or comorbidities. In non-Aboriginal adults, cardiovascular disease (34% was the predominant comorbidity whilst excessive alcohol use (66% was the most commonly reported risk factor in Aboriginal adults. In adults, comorbidities were more frequently reported among those in metropolitan regions than those in non-metropolitan regions. Vaccination status was unknown for 637 of 1,082 cases post-July 2001. Forty-one percent of non-Aboriginal and 60% of Aboriginal children were eligible for vaccination but were not vaccinated. Among adults with risk factors who were eligible for vaccination and with known vaccination status, 75% Aboriginal and 94% non-Aboriginal were not vaccinated. An all-of-life immunisation register is needed to evaluate vaccine coverage and effectiveness in preventing IPD in adults.

  20. Gendering Aboriginalism: A Performative Gaze on Indigenous Australian Women

    Directory of Open Access Journals (Sweden)

    Katelyn Barney

    2010-03-01

    Full Text Available One of the most common Aboriginalist representations of Indigenous Australian people is, as Indigenous female performer Lou Bennett points out, ‘basically a man, out in the desert, black skin, flat nose with a lap-lap on, standing on one leg, resting against a spear’. Her comment raises many issues. In what ways are discourses of Aboriginalism gendered? How does Aboriginalism affect performance and specifically Aboriginal women performers? In exploring these questions, I examine Aboriginalist representations of Aboriginal women performers by white male scholars and the role of women anthropologists in the production of Aboriginalist discourse about Aboriginal women.

    Full Text Available One of the most common Aboriginalist representations of Indigenous Australian people is, as Indigenous female performer Lou Bennett points out, ‘basically a man, out in the desert, black skin, flat nose with a lap-lap on, standing on one leg, resting against a spear’.

    2010-01-01

    Traditional Aboriginal Australian cultures include a significant astronomical component, perpetuated through oral tradition and ceremony. This knowledge has practical navigational and calendrical functions, and sometimes extends to a deep understanding of the motion of objects in the sky. Here we explore whether this astronomical tradition is reflected in the rock art of Aboriginal Australians. We find several plausible examples of depictions of astronomical figures and symbols, and also evidence that astronomical observations were used to set out stone arrangements. However, we recognise that the case is not yet strong enough to make an unequivocal statement, and describe our plans for further research.

  3. Mining the Midden: A Facility for Dynamic Waste Harvesting at the Cedar Hills Regional Landfill

    Science.gov (United States)

    Allan, Aaron

    Mining the Midden intends to re-frame the sanitary landfill as a new typology of public land containing an embodied energy of cultural and material value. By reconnecting the public with the landfill and seriously exposing its layers of history and then digesting both mined and new waste within an industrial facility of materials recovery and plasma gasification technology waste-to-energy plant. The sequence of experience for a public visitor begins where the waste is transformed to energy and flows in the opposite direction of the trash through the facility and then into the active landfill mining operation which is the large site component of the project. The mine is flanked by the visitor path, which is suspended from the soldier piles of the excavation system and allows the visitor to interpret along the 1/3 mile path their personal connection to the waste stream and the consumption patterns which drive our waste. Interpretation results from multi-sensory experience of the open mine and its connection to the processing structure as one hovers above, through moments of seeing through structural glass lagging directly into the sectional cut of the landfill, and through cultural artifacts harvested by landfill archaeologists which are displayed in rhythm with the structure and lagging. The culmination of the prescribed path is a narrow cut which frames the view of Mt. Rainier in the distance and opens up a visual connection with the remaining majority of the landfill which have up to this point been blocked by the small mountain of trash which they just walked up and through. This thesis intends that by confronting people with the juxtapositions of 2 potentially destructive mounds or mountains, and how we as a culture value and protect land while we simultaneously dump our rubbish on other lands, this experience will make the visitor more conscious of ones personal contribution to our culture of disposable commodities.

    Of the hundreds of distinct Aboriginal cultures of Australia, many have oral traditions rich in descriptions and explanations of comets, meteors, meteorites, airbursts, impact events, and impact craters. These views generally attribute these phenomena to spirits, death, and bad omens. There are also many traditions that describe the formation of meteorite craters as well as impact events that are not known to Western science.

    Ashton, C W; Duffie-Ashton, Denise

    2008-01-01

    Resource accounting principles provide more effective planning for Aboriginal healthcare delivery through driving best management practices, efficacious techniques for long-term resource allocation, transparency of information and performance measurement. Major improvements to Aboriginal health in New Zealand and Australia were facilitated in the context of this public finance paradigm, rather than cash accounting systems that remain the current method for public departments in Canada. Multiple funding sources and fragmented delivery of Aboriginal healthcare can be remedied through similar adoption of such principles.

  11. Oxygen isotope ratios in the shell of Mytilus edulis: archives of glacier meltwater in Greenland?

    Versteegh, E. A. A.; Blicher, M. E.; Mortensen, J.; Rysgaard, S.; Als, T. D.; Wanamaker, A. D., Jr.

    2012-09-01

    Melting of the Greenland Ice Sheet (GrIS) is accelerating and will contribute significantly to global sea level rise during the 21st century. Instrumental data on GrIS melting only cover the last few decades, and proxy data extending our knowledge into the past are vital for validating models predicting the influence of ongoing climate change. We investigated a potential meltwater proxy in Godthåbsfjord (West Greenland), where glacier meltwater causes seasonal excursions with lower oxygen isotope water (δ18Ow) values and salinity. The blue mussel (Mytilus edulis) potentially records these variations, because it precipitates its shell calcite in oxygen isotopic equilibrium with ambient seawater. As M. edulis shells are known to occur in raised shorelines and kitchen middens from previous Holocene warm periods, this species may be ideal in reconstructing past meltwater dynamics. We investigate its potential as a palaeo-meltwater proxy. First, we confirmed that M. edulis shell calcite oxygen isotope (δ18Oc) values are in equilibrium with ambient water and generally reflect meltwater conditions. Subsequently we investigated if this species recorded the full range of δ18Ow values occurring during the years 2007 to 2010. Results show that δ18Ow values were not recorded at very low salinities (future research will expand on the geographical and temporal range of the shell measurements by sampling mussels in other fjords in Greenland along a south-north gradient, and by sampling shells from raised shorelines and kitchen middens from prehistoric settlements in Greenland.

  12. Stable Isotopic Shifts in Fish Bones from Multiple Archeological Coastal Middens in Penobscot Bay, Maine

    The carbon and nitrogen stable isotope compositions of collagen extracted from well-preserved archeological fish bones has the potential to provide useful information on fish diets and food web dynamics over time. Previous work on the Turner Farm archaeological site in Penobscot Bay, Gulf of Maine, reveals significant shifts in fish diets have occurred since European colonization (post 1620’s). The objective of the present study was to analyze samples from other archaeological sites within Penobscot Bay to characterize the spatial extent of the isotopic shift measured at Turner Farm. Stratified cod, flounder, and sculpin bones were analyzed from eight coastal middens located approximately 50km apart from one another within Penobscot Bay. The bones were sampled from three time horizons (0kya, 0.5-1kya, and 2.2-2.4kya). All bone samples were demineralized in 0.2M HCl at 4°C for 2 to 7 days and then extracted in 0.25M NaOH at 4°C for 1 to 2 hours. After freeze-drying, the bulk isotopic composition of each sample was analyzed using the EA-IRMS. In all stratigraphic horizons analyzed, cod were more enriched in δ13C and δ15N than sculpin, and flounder were the most depleted in δ13C and δ15N . However, the isotopic offsets between the fish species decreased from 2.4kya to the present. The nitrogen isotope composition was relatively constant over time and space for all species, implying that trophic levels for the fishes analyzed have not changed significantly in Penobscot Bay for the last 2,400 years. The carbon isotope composition also appears to be constant spatially in Penobscot Bay, however, the modern signal was more depleted than the paleo signal in all three species. The difference between the modern and paleo δ13C is ~5‰ for cod and flounder, and ~9‰ for sculpin. These shifts may, in part, be explained by decreases in both primary producer and prey species diversity, as kelp forests replace eelgrass beds in the Gulf of Maine.

  13. Disparities in healthcare utilisation rates for Aboriginal and non-Aboriginal Albertan residents, 1997-2006: a population database study.

    Directory of Open Access Journals (Sweden)

    Helen Chung

    Full Text Available BACKGROUND: It is widely recognised that significant discrepancies exist between the health of indigenous and non-indigenous populations. Whilst the reasons are incompletely defined, one potential cause is that indigenous communities do not access healthcare to the same extent. We investigated healthcare utilisation rates in the Canadian Aboriginal population to elucidate the contribution of this fundamental social determinant for health to such disparities. METHODS: Healthcare utilisation data over a nine-year period were analysed for a cohort of nearly two million individuals to determine the rates at which Aboriginal and non-Aboriginal populations utilised two specialties (Cardiology and Ophthalmology in Alberta, Canada. Unadjusted and adjusted healthcare utilisation rates obtained by mixed linear and Poisson regressions, respectively, were compared amongst three population groups - federally registered Aboriginals, individuals receiving welfare, and other Albertans. RESULTS: Healthcare utilisation rates for Aboriginals were substantially lower than those of non-Aboriginals and welfare recipients at each time point and subspecialty studied [e.g. During 2005/06, unadjusted Cardiology utilisation rates were 0.28% (Aboriginal, n = 97,080, 0.93% (non-Aboriginal, n = 1,720,041 and 1.37% (Welfare, n = 52,514, p = <0.001]. The age distribution of the Aboriginal population was markedly different [2.7%≥65 years of age, non-Aboriginal 10.7%], and comparable utilisation rates were obtained after adjustment for fiscal year and estimated life expectancy [Cardiology: Incidence Rate Ratio 0.66, Ophthalmology: IRR 0.85]. DISCUSSION: The analysis revealed that Aboriginal people utilised subspecialty healthcare at a consistently lower rate than either comparatively economically disadvantaged groups or the general population. Notably, the differences were relatively invariant between the major provincial centres and over a nine year period

  14. Corporate social responsibility and aboriginal relations

    International Nuclear Information System (INIS)

    All of Canada's uranium mining activity occurs in the northern half of the province of Saskatchewan in western Canada. This region has a total population of 38 000 people living in many small communities scattered over 250 000 square kilometres. Demographically, the north's population is 75% aboriginal representing the Woodland Cree, Dene, and Metis Nations. The majority of the aboriginal population of northern Saskatchewan are treaty Indians (First Nations). The dominant first nations group in the north is The Lac La Ronge Indian Band, also Saskatchewan's largest Woodland Cree First Nation. Despite the fact that the Lac La Ronge Band and other First Nations of the region do not have surface or mineral rights, other than those on their reserve lands, they have significant influence in the development process. The extraction of the mineral resources of Canada are now undertaken with very considerable input from first nations groups and with sensitivity to their treaty rights and aboriginal traditional rights. Treaty rights in Canada include, among other things, hunting and fishing, access to post secondary education and special taxation considerations. This presentation will introduce participants to a unique perspective on northern Saskatchewan's uranium mining industry. This perspective will be provided by Harry Cook, Chief of the Lac La Ronge Indian Band.In his presentation, Chief Cook will provide a first nation's perspective on industrial development generally and uranium development specifically. He will begin by outlining the challenges facing aboriginal people in Canada and will provide an insightful view of the historical conflict between industrial developers and first nations people. He will describe the aspirations of his people and the importance they place on preservation of the natural environment. He will also speak to the critical need now emerging for aboriginal people to seek a balance between retaining traditional culture and participating in the

  15. Chronic liver disease in Aboriginal North Americans

    2008-01-01

    A structured literature review was performed to detail the frequency and etiology of chronic liver disease (CLD) in Aboriginal North Americans. CLD affects Aboriginal North Americans disproportionately and is now one of the most common causes of death.Alcoholic liver disease is the leading etiology of CLD,but viral hepatitis, particularly hepatitis C, is an important and growing cause of CLD. High rates of autoimmune hepatitis and primary biliary cirrhosis (PBC) are reported in regions of coastal British Columbia and southeastern Alaska. Non-alcoholic liver disease is a common, but understudied, cause of CLD.Future research should monitor the incidence and etiology of CLD and should be geographically inclusive.In addition, more research is needed on the treatment of hepatitis C virus (HCV) infection and non-alcoholicfatty liver disease (NAFLD) in this population.

  16. Strongyloidiasis: an issue in Aboriginal communities.

    Adams, M; Page, W; Speare, R

    2003-01-01

    Strongyloidiasis, a disease caused by the parasitic gut nematode (roundworm), Strongyloides stercoralis, has the highest prevalence in the world in rural and remote Aboriginal communities of northern Australia. With prevalences greater than 25%, these communities have rates of strongyloidiasis higher those in the worst affected developing countries where surveys have been recently conducted. Available data indisputably support that strongyloidiasis is more prevalent in rural and remote Aboriginal communities than in the mainstream Australian community. However control of strongyloidiasis has not been given a high priority by government health departments, with the result that Aboriginal people in remote and rural communities in Northern Australia are still suffering from a preventable and treatable disease. This article suggests that the only way to address the strongyloidiasis problem in Indigenous communities is to have strongyloidiasis recognised and addressed at the national level. One component of this must be making health departments responsible for establishing appropriate systems of effective treatment for and monitoring of patients with strongyloidiasis. PMID:15877491

    Australia was one of the earliest regions outside Africa to be colonized by fully modern humans, with archaeological evidence for human presence by 47,000 years ago (47 kya) widely accepted [1, 2]. However, the extent of subsequent human entry before the European colonial age is less clear. The dingo reached Australia about 4 kya, indirectly implying human contact, which some have linked to changes in language and stone tool technology to suggest substantial cultural changes at the same time [3]. Genetic data of two kinds have been proposed to support gene flow from the Indian subcontinent to Australia at this time, as well: first, signs of South Asian admixture in Aboriginal Australian genomes have been reported on the basis of genome-wide SNP data [4]; and second, a Y chromosome lineage designated haplogroup C(∗), present in both India and Australia, was estimated to have a most recent common ancestor around 5 kya and to have entered Australia from India [5]. Here, we sequence 13 Aboriginal Australian Y chromosomes to re-investigate their divergence times from Y chromosomes in other continents, including a comparison of Aboriginal Australian and South Asian haplogroup C chromosomes. We find divergence times dating back to ∼50 kya, thus excluding the Y chromosome as providing evidence for recent gene flow from India into Australia. PMID:26923783

  18. Consulting Whom? Lessons from the Toronto Urban Aboriginal Strategy

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available The research conducted here looks at the current Urban Aboriginal Strategy (UAS in Toronto. The purpose of this Strategy is to provide long-term investments to support Aboriginal communities in urban settings by focusing on three priority areas: improving life skills; promoting job training, skills, and entrepreneurship; and supporting Aboriginal women, children, and families. This article seeks to answer the following question: Does the UAS provide Aboriginal participants with the ability to effectively participant in the consultation process? It argues that the UAS process of consulting with the urban Aboriginal community does not allow for the effective participation of Aboriginal peoples because of problematics related to consulting in an urban setting and despite the language of partnership, the federal government still reserves the right to make final decisions. These problems diminish the ability to build renewed Aboriginal-State relations based on mutual respect and trust, which has been absent within the Aboriginal-State apparatus and resulted in the political exclusion of Aboriginals in Canada. Though consultation can be a vehicle for empowering participants with decision-making authority, this is not the case in Toronto. The lack of a common vision, political buy-in, and the aura of secrecy leads to a political relationship built on mistrust. Mistrust between members and government renders the consultation process ineffective. This article combines the literature on public consultations with official government documents to identify critical components that must be evident for consultations to be fruitful and participation effective. These criteria are the benchmarks upon which to measure effectiveness. Based on interviews with the Steering Committee, this article finds that the UAS process of consulting with the Toronto Aboriginal community does not enable Aboriginal participants to effectively participate in the democratic process.

    This paper presents paleoecological analyses of 48 fossil arctic ground squirrel ( Spermophilus parryii) middens (nests and caches) recovered from ice-rich loess sediments in the Klondike region of west-central Yukon Territory. AMS radiocarbon dates and stratigraphic association of middens with Dawson tephra (˜25 300 14C yr BP), indicate these paleoecological data reflect the onset of glacial conditions of early Marine Isotope Stage (MIS) 2 and terminal MIS 3 (˜24 000-29 450 14C yr BP). Plant macrofossils include at least 60 plant taxa, including diverse graminoids ( Poa, Elymus trachycaulus, Kobresia myosuroides), steppe forbs ( Penstemon gormanii, Anemone patens var. multifida, Plantago cf. canescens), tundra forbs ( Draba spp., Bistorta vivipara), dwarf shrubs ( Salix cf. arctica, S. cf. polaris), sage ( Artemisia frigida) and rare trees ( Picea mariana). Many of these taxa identified in the middens represent the first recorded fossils for these plants in Eastern Beringia and add to our knowledge of the floristic composition of Pleistocene vegetation and biogeography in this region. Fossil beetles include typical members of the Eastern Beringian steppe-tundra fauna ( Lepidophorus lineaticollis and Connatichela artemisiae) and others suggesting predominantly dry, open habitats. Cache forage selection is suggested by some plant taxa which were particularly frequent and abundant in the middens ( Bistorta vivipara, Kobresia myosuroides, Ranunculus spp., Potentilla, Erysimum cf. cheiranthoides, Poa, Carex and Draba). Factors such as proximity of vegetation to burrows and abundance of fruits and seeds per plant were probably important in cache selection. Glacial conditions enabled arctic ground squirrels to form widespread and dense populations in regions such as the Klondike in which they are rare or absent at present. This fossil midden record supports previous hypotheses that suggest arctic ground squirrels evolved in and are well-adapted to the open, steppe

    Issue addressed Tobacco consumption contributes to health disparities among Aboriginal Australians who experience a greater burden of smoking-related death and diseases. This paper reports findings from a baseline survey on factors associated with smoking, cessation behaviours and attitudes towards smoke-free homes among the Aboriginal population in inner and south-western Sydney. Methods A baseline survey was conducted in inner and south-western Sydney from October 2010 to July 2011. The survey applied both interviewer-administered and self-administered data collection methods. Multiple logistic regression was performed to determine the factors associated with smoking. Results Six hundred and sixty-three participants completed the survey. The majority were female (67.5%), below the age of 50 (66.6%) and more than half were employed (54.7%). Almost half were current smokers (48.4%) with the majority intending to quit in the next 6 months (79.0%) and living in a smoke-free home (70.4%). Those aged 30-39 years (AOR 3.28; 95% CI: 2.06-5.23) and the unemployed (AOR 1.67; 95% CI: 1.11-2.51) had higher odds for current smoking. Participants who had a more positive attitude towards smoke-free homes were less likely to smoke (AOR 0.79; 95% CI: 0.74-.85). Conclusions A high proportion of participants were current smokers among whom intention to quit was high. Age, work status and attitudes towards smoke-free home were factors associated with smoking. So what? The findings address the scarcity of local evidence crucial for promoting cessation among Aboriginal tobacco smokers. Targeted promotions for socio-demographic subgroups and of attitudes towards smoke-free homes could be meaningful strategies for future smoking-cessation initiatives. PMID:26235612

    We investigated disparities in rates of acute myocardial infarction (AMI) between Aboriginal and non-Aboriginal people in the 199 Statistical Local Areas (SLAs) in New South Wales, Australia. Using routinely collected and linked hospital and mortality data from 2002 to 2007, we developed multilevel Poisson regression models to estimate the relative rates of first AMI events in the study period accounting for area of residence. Rates of AMI in Aboriginal people were more than two times that in non-Aboriginal people, with the disparity greatest in more disadvantaged and remote areas. AMI rates in Aboriginal people varied significantly by SLA, as did the Aboriginal to non-Aboriginal rate ratio. We identified almost 30 priority areas for universal and targeted preventive interventions that had both high rates of AMI for Aboriginal people and large disparities in rates.

    Seawater pH and the availability of carbonate ions are decreasing due to anthropogenic carbon dioxide emissions, posing challenges for calcifying marine species. Marine mussels are of particular concern given their role as foundation species worldwide. Here, we document shell growth and calcification patterns in Mytilus californianus, the California mussel, over millennial and decadal scales. By comparing shell thickness across the largest modern shells, the largest mussels collected in the 1960s-1970s and shells from two Native American midden sites (∼1000-2420 years BP), we found that modern shells are thinner overall, thinner per age category and thinner per unit length. Thus, the largest individuals of this species are calcifying less now than in the past. Comparisons of shell thickness in smaller individuals over the past 10-40 years, however, do not show significant shell thinning. Given our sampling strategy, these results are unlikely to simply reflect within-site variability or preservation effects. Review of environmental and biotic drivers known to affect shell calcification suggests declining ocean pH as a likely explanation for the observed shell thinning. Further future decreases in shell thickness could have significant negative impacts on M. californianus survival and, in turn, negatively impact the species-rich complex that occupies mussel beds.

    Full Text Available Gaining an understanding of how best to support the development of Aboriginal children is important in promoting positive social, emotional, educational, and health outcomes. The purpose of the current study was to identify the most important elements of healthy development for Aboriginal children, with a particular focus on social-emotional development. Focus groups were conducted with 37 Aboriginal Canadians, including parents, service providers, adolescents, and young adults. Five inter-connected themes emerged: cultural wellness, emotional wellness, mental wellness, social wellness, and strong identity, with strong identity described as central and foundational to the other themes. This study strengthens the assertion that Aboriginal children require an additional set of social-emotional skills to successfully navigate different cultural contexts during development. Implications for research and practice are discussed.

    Well-documented health disparities between Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) and non-Aboriginal Australians are underpinned by complex historical and social factors. The effects of colonisation including racism continue to impact negatively on Aboriginal health outcomes, despite being under-recognised and under-reported. Many Aboriginal people find hospitals unwelcoming and are reluctant to attend for diagnosis and treatment, particularly with few Aboriginal health professionals employed on these facilities. In this paper, scientific literature and reports on Aboriginal health-care, methodology and cross-cultural education are reviewed to inform a collaborative model of hospital-based organisational change. The paper proposes a collaborative model of care to improve health service delivery by building capacity in Aboriginal and non-Aboriginal personnel by recruiting more Aboriginal health professionals, increasing knowledge and skills to establish good relationships between non-Aboriginal care providers and Aboriginal patients and their families, delivering quality care that is respectful of culture and improving Aboriginal health outcomes. A key element of model design, implementation and evaluation is critical reflection on barriers and facilitators to providing respectful and culturally safe quality care at systemic, interpersonal and patient/family-centred levels. Nurses are central to addressing the current state of inequity and are pivotal change agents within the proposed model. PMID:22530862

    During the energy crises of 1973 and 1980 the western world mainly depended on countries around the Persian Golf for its oil supplies: Saudi Arabia, Iran, Iraq, Kuwait and the United Arab Emirates. Again the world is facing a major challenge because of the highly increased oil price. Moreover, more energy must be produced for a growing world population whereas at the same time the amount of greenhouse gasses emitted must be reduced. Strict government policy for security of supply and environment is a prerequisite. The question arises whether oil from the Middle East will once again play an important role in the coming decades in order to meet the growing demand for fuel. [mk]. [Dutch] Tijdens de energiecrises van 1973 en 1980 was het westen voor zijn olieleveranties voornamelijk afhankelijk van de landen rond de Perzische Golf: Saoedi-Arabie, Iran, Irak, Koeweit en de Verenigde Arabische Emiraten. De wereld staat opnieuw voor een enorme uitdaging omdat de olieprijs flink is gestegen. Ook moet meer energie worden geproduceerd voor een groeiende wereldbevolking terwijl tegelijkertijd de hoeveelheid broeikasgassen moet worden gereduceerd. Strikt overheidsbeleid ten aanzien van voorzieningszekerheid en milieu is hierbij een belangrijke vereiste. De vraag is of de olie uit het Midden-Oosten wederom een sleutelrol gaat spelen in de komende tientallen jaren om de groeiende behoefte aan brandstof te voorzien.

  5. Oxygen isotope ratios in the shell of Mytilus edulis: archives of glacier meltwater in Greenland?

    Directory of Open Access Journals (Sweden)

    T. D. Als

    2012-09-01

    Full Text Available Melting of the Greenland Ice Sheet (GrIS is accelerating and will contribute significantly to global sea level rise during the 21st century. Instrumental data on GrIS melting only cover the last few decades, and proxy data extending our knowledge into the past are vital for validating models predicting the influence of ongoing climate change. We investigated a potential meltwater proxy in Godthåbsfjord (West Greenland, where glacier meltwater causes seasonal excursions with lower oxygen isotope water (δ18Ow values and salinity. The blue mussel (Mytilus edulis potentially records these variations, because it precipitates its shell calcite in oxygen isotopic equilibrium with ambient seawater. As M. edulis shells are known to occur in raised shorelines and kitchen middens from previous Holocene warm periods, this species may be ideal in reconstructing past meltwater dynamics. We investigate its potential as a palaeo-meltwater proxy. First, we confirmed that M. edulis shell calcite oxygen isotope (δ18Oc values are in equilibrium with ambient water and generally reflect meltwater conditions. Subsequently we investigated if this species recorded the full range of δ18Ow values occurring during the years 2007 to 2010. Results show that δ18Ow values were not recorded at very low salinities (M. edulis δ18Oc values are suitable in reconstructing past meltwater amounts in most cases, but care has to be taken that shells are collected not too close to a glacier, but rather in the mid region or mouth of the fjord. The focus of future research will expand on the geographical and temporal range of the shell measurements by sampling mussels in other fjords in Greenland along a south-north gradient, and by sampling shells from raised shorelines and kitchen middens from prehistoric settlements in Greenland.

    Injury is the leading cause of death among children and youth in Canada. Significant disparities in injury mortality rates have been observed between Aboriginal and non-Aboriginal populations, but little is known about the age-, sex-, and mechanism-specific patterns of injury causing death. This study examines paediatric mortality in British Columbia from 2001 to 2009 using comprehensive vital statistics registry data. We highlight important disparities in Aboriginal and non-Aboriginal mortality rates, and use the Preventable Years of Life Lost (PrYLL) metric to identify differences between age groups and the mechanisms of injury causing death. A significantly greater age-adjusted mortality rate was observed among Aboriginal children (OR = 2.08, 95% CI: 1.41, 3.06), and significantly higher rates of death due to assault, suffocation, and fire were detected for specific age groups. Mapped results highlight regional disparities in PrYLL across the province, which may reflect higher Aboriginal populations in rural and remote areas. Crucially, these disparities underscore the need for community-specific injury prevention policies, particularly in regions with high PrYLL. PMID:27399748

    2007-11-15

    The development of Alberta's oilsands industry offers significant opportunities to Aboriginal communities located at the centre of development. Although resource development poses challenges in terms of traditional lifestyles and the environment, it has also resulted in the creation of thriving companies offering economic advantages to individuals and communities. The Northeastern Alberta Aboriginal Business Association (NAABA) has stated that between $400 and $500 million work of Aboriginal business is being conducted annually in the Regional Municipality of Wood Buffalo. This article described success stories of the labour, products and services targeted at the oilsands industry that these businesses provide. The operations of the Fort McKay Group of Companies (FMGC), Cold Lake First Nations, and Primco Dene were highlighted. It was shown that joint ventures have helped many Aboriginal companies diversify and grow. Partnerships were shown to be a viable way to share the wealth of the oilsands with Aboriginal communities, many of which are remote and have high unemployment rates and few opportunities for development. Some opportunities for development include band-owned mines, and progress in biofuels. 4 figs.

    2008-08-01

    Full Text Available There is debate about how the Aboriginal past can and should be memorialised. This paper utilises a series of example memorials to discuss the ways in which Indigenous and non-Indigenous people in Australia are choosing to depict – in a physical, public form – Aboriginal perspectives of the past. The paper focuses on the issues of cultural evolution and the adoption of so-called ‘European’ ways of memorialising. It also looks at the role of landscapes and natural materials in memorials to the Aboriginal past and the evolving role of counter- and anti-memorials to commemorate the past. The examples of memorials from around Australia suggest that, above all, we must be open-minded about what constitutes an ‘Aboriginal’ memorial. Ways of memorialising the Aboriginal past can range, for example, from natural to constructed, from created by Indigenous people exclusively to otherwise, and from targeting an exclusively Indigenous audience, a non-Indigenous audience, or both. There is more than one way of memorialising the Aboriginal past.

    Aboriginal land managers have observed that feral Asian water buffalo ( Bubalis bubalis Lydekker) are threatening the ecological and cultural integrity of perennial freshwater sources in Arnhem Land, Australia. Here we present collaborative research between the Aboriginal Rangers from Warddeken Land Management Limited and Western scientists which quantified the ground-level impacts of buffalo on seven perennial freshwater springs of the Arnhem Plateau. A secondary aim was to build the capacity of Aboriginal Rangers to self-monitor and evaluate the ecological outcomes of their land management activities. Sites with high buffalo abundance had significantly different ground, ground cover, and water quality attributes compared to sites with low buffalo abundance. The low buffalo abundance sites were characterized by tall herbaceous vegetation and flat ground, whereas wallows, bare ground, and short ungrazed grasses were indicators of sites with high buffalo abundance. Water turbidity was greater when buffalo abundance was high. The newly acquired monitoring skills and derived indicators of buffalo damage will be used by Aboriginal Rangers to assess the ecological outcomes of their future buffalo control efforts on the Arnhem Plateau.

    By the 1970s, a number of dermatoglyphic studies of Taiwan aborigines (Gaoshan nationality) had been published, however in each only a few dermatoglyphic variables were addressed. Since that time, little new research has been conducted. In this study, we collected and analyzed the dermatoglyphs of 100 individuals of Kavalan, a Taiwan aboriginal population, and we reported a wide range of dermatoglyphic variables including total finger ridge count (TFRC), a-b total ridge count (a-b RC), atd angle and axial triradius percent distance (tPD), and frequencies of fingerprint pattern, palmar thenar pattern, palmar interdigital pattern, palmar hypothenar pattern, and simian line. This study is the first comprehensive dermatoglyphic research of any Taiwan aboriginal population.

  1. The Australian Aboriginal People: How to Misunderstand Their Science

    CERN Document Server

    Norris, Ray P

    2014-01-01

    Just one generation ago, schoolkids were taught that Aboriginal people couldn't count beyond five, wandered the desert scavenging for food, had no civilization or religion, had no agriculture, couldn't navigate, didn't build houses, and peacefully acquiesced when Western Civilisation rescued them in 1788. How did we get it so wrong? Here I show that traditional Aboriginal people knew a great deal about the sky, knew the cycles of movements of the stars and the complex motions of the sun, moon and planets. I argue that school students studying science today could learn much from the way that pre-contact Aboriginal people used observation to build a self-consistent picture of the world around them, with predictive power and practical applications.

  2. An Aboriginal game plan - a plan for success

    International Nuclear Information System (INIS)

    A presentation is included of some of the more intangible and hands-on types of advice that a corporation should consider when they decide to do business with Canadian Aboriginal peoples. Although there are numerous areas of business concern (both legally and culturally) to consider when working with Aboriginal people and communities, developing a proactive strategy and approach to this segment of Canadian society is just as important and compelling as environmental or gender-related issues because they too can be seen to affect the company operations at any level. Having good corporate business relations with Aboriginal communities is going to take some thinking 'outside of the box,' but with committed understanding and focus on open communications, there is no reason why a company should not be able to develop a corporate-wide approach with relative ease. By being open to learning and listening, companies can begin to develop 'Aboriginal Relations' strategies that will become an automatic inclusion item at corporate strategy meetings and planning discussions. This would be in keeping with the corporation's choice to negotiate and not litigate

  3. Dawes Review 5: Australian Aboriginal Astronomy and Navigation

    Norris, Ray P.

    2016-08-01

    The traditional cultures of Aboriginal Australians include a significant astronomical component, perpetuated through oral tradition, ceremony, and art. This astronomical knowledge includes a deep understanding of the motion of objects in the sky, which was used for practical purposes such as constructing calendars and for navigation. There is also evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, recorded unexpected phenomena such as eclipses and meteorite impacts, and could determine the cardinal points to an accuracy of a few degrees. Putative explanations of celestial phenomena appear throughout the oral record, suggesting traditional Aboriginal Australians sought to understand the natural world around them, in the same way as modern scientists, but within their own cultural context. There is also a growing body of evidence for sophisticated navigational skills, including the use of astronomically based songlines. Songlines are effectively oral maps of the landscape, and are an efficient way of transmitting oral navigational skills in cultures that do not have a written language. The study of Aboriginal astronomy has had an impact extending beyond mere academic curiosity, facilitating cross-cultural understanding, demonstrating the intimate links between science and culture, and helping students to engage with science.

  9. The constitutional duty to consult aboriginal peoples in Canada

    International Nuclear Information System (INIS)

    The intent of the presentation would be to share our views that the Canadian Nuclear Safety Commission, as a court of record and an administrative tribunal with powers of quasi-judicial nature, is empowered to satisfy the constitutional duty to consult with Aboriginal people in Canada for nuclear related projects that fall within its mandate. We would also touch on the fact that the Commission is also responsible to conduct environmental assessments of uranium and nuclear related projects that may affect Aboriginal peoples, their traditional territories or their traditional way of life. Recent Canadian court decisions have recognized that administrative tribunals, such as the Commission, may be the appropriate agencies to address the duty to consult Aboriginal peoples on behalf of the Crown under section 35 of the Canadian Constitution (1867). The Supreme Court of Canada has also recognized that administrative tribunals such as the Commission may have the statutory authority to decide questions of law for subject matters that fall within their mandate and expertise. Consequently, it is now generally accepted that the Commission has jurisdiction to consider if the duty to consult with Aboriginal Peoples is indeed satisfied. This is of particular importance given that the Commission has the exclusive jurisdiction in Canada to regulate all matters related to nuclear including the implementation of international obligations Canada has agreed to. Failure to appropriately consult with Aboriginal peoples may also result in a constitutional challenge where Canadian courts may reverse a licensing decision in relation to major projects such as a uranium mine, a nuclear power facility or a deep geologic repository.

  10. Why should Aboriginal peoples learn to write?

    Directory of Open Access Journals (Sweden)

    Carles Serra Pagès

    2010-06-01

    Full Text Available Cultures and worldviews are inscribed by means of ‘writing’, or what Derrida calls ‘the perdurable inscription of a sign’ (Of Grammatology. A sign is the union between signifier and signified. The signifier may be natural (clouds indicate that it is going to rain or artificial. All cultures are made up of relations that stay at the level of signs, that is, everything that belongs to culture is empirical and conventional. In this regard, both Aboriginal and Western culture remain at the same level. Moreover, both cultures produce objectivity by means of contrast and experimentation, in the design of a sharp object, for example an arrow or a knife. In Ancient Greece, Havelock contends that the invention of writing dramatically increased the possibilities of objective thought (The Muse Learns To Write, but it also created a logic of binaries that transcended the objectivity of science and transpired into the ideology behind colonialism. In this context, the role of writing is analyzed in David Malouf’s Remembering Babylon. How does writing affect Gemmy all throughout the book? Already in the first Chapter, the teacher and the minister of the colony analyze Gemmy ‘in writing’. Gemmy knows what writing is but hasn’t learnt its ‘trick’: he does not know how to read or write. All he can see is that what he tells about his life, all his pain and suffering, is translated into marks and magic squiggles on the paper: only the spirit of the story he tells is captured. But little by little, the cognitive effects of writing get hold of Gemmy, until he starts to understand his life within the framework of the logic of binaries and identity upon which all reflective thought and science rest. All in all, this deconstructive reading can be seen as a critique of Europe’s modern idea of the autonomy of reason, in the name of a heteronymous rationality in the form of writing.

    Mikkelsen, Paula M

    2002-01-01

    In his contributions to the monographic series "Manual of Conchology", Henry Pilsbry reviewed the subgroup Tectibranchiata, comprising those opisthobranch snails that (at least primitively) still possess a shell (Pilsbry, 1894-1896). Exemplified by the Cephalaspidea (bubble shells), others included in this group at Pilsbry's time and since were Anaspidea (sea hares) and the shelled members of Notaspidea (side-gilled slugs) and Sacoglossa (leaf slugs). Pilsbry (and others since his time) considered tectibranchs to be the "root stock" from which more advanced gastropods such as Nudibranchia and Pulmonata were derived. Tectibranch systematics is firmly based on conchology and most species were originally described from empty shells. However, soft-anatomical characters were acknowledged quite early on as equally important in tectibranchs, due to the reduction of their shells and their evolutionary proximity to unshelled gastropods. Today, Tectibranchiata is not recognized as a natural taxon although the word "tectibranch" (like "prosobranch" and "mesogastropod") continues in vernacular use. Shelled opisthobranchs have been redistributed among various taxa, including several new ones--the unresolved basal opisthobranchs (Architectibranchia) and the "lower Heterobranchia", an enigmatic and currently much-studied group of families considered basal to all of Euthyneura (Opisthobranchia and landsnails (Pulmonata)). Despite their polyphyletic status, shelled opisthobranchs remain important subjects in evolutionary studies of gastropods--as the most basal members of nearly every opisthobranch clade and as organisms with mosaic combinations of primitive and derived features within evolutionary "trends" (e.g., loss of the shell, detorsion, concentration of the nervous system, ecological specialization, etc.). Although they play a pivotal role, the shelled opisthobranchs have received minimal attention in more comprehensive gastropod studies, often relegated to token

    The 1993-98 Aboriginal Health Strategic Plan for South Western Sydney represented the first partnership of its kind between an Area Health Service, local Aboriginal Health Workers and the local Aboriginal Community Controlled Health Service in Australia. During 1998, an evaluation of the plan was undertaken as part of the preparation for the second Aboriginal Health Plan. Of the 45 strategies in the first plan, 38% had been fully implemented, 42% had been partly implemented, and 20% were not implemented at all. This paper discusses the importance of data collection and monitoring systems, the integration of Aboriginal health into mainstream services, the further development of Aboriginal health infrastructure, and continued leadership by senior managers.

  16. The use of joint ventures to accomplish aboriginal economic development: Two examples from British Columbia

    Directory of Open Access Journals (Sweden)

    Jeremy Boyd

    2009-09-01

    Full Text Available “Aboriginal economic development” differs from other forms of development by emphasizing aboriginal values and community involvement. Joint ventures, while providing business advantages, may not be able to contribute to aboriginal economic development. This paper examines two joint ventures in the interior of British Columbia to examine their ability or inability to contribute the extra dimensions of development desired by aboriginal communities. The AED framework examines business structure; profitability; employment; aboriginal capacity in education, experience, and finance; preservation of traditional values, culture and language; control of forest management over traditional territory; and community support. Established in the context of unresolved land claims, both enterprises partially contribute to aboriginal economic development, but in different ways and with different overall results.

  17. On the Astronomical Knowledge and Traditions of Aboriginal Australians

    Science.gov (United States)

    Hamacher, Duane W.

    2011-12-01

    Historian of science David Pingree defines science in a broad context as the process of systematically explaining perceived or imaginary phenomena. Although Westerners tend to think of science being restricted to Western culture, I argue in this thesis that astronomical scientific knowledge is found in Aboriginal traditions. Although research into the astronomical traditions of Aboriginal Australians stretches back for more than 150 years, it is relatively scant in the literature. We do know that the sun, moon, and night sky have been an important and inseparable component of the landscape to hundreds of Australian Aboriginal groups for thousands (perhaps tens-of-thousands) of years. The literature reveals that astronomical knowledge was used for time keeping, denoting seasonal change and the availability of food sources, navigation, and tidal prediction. It was also important for rituals and ceremonies, birth totems, marriage systems, cultural mnemonics, and folklore. Despite this, the field remains relatively unresearched considering the diversity of Aboriginal cultures and the length of time people have inhabited Australia (well over 40,000 years). Additionally, very little research investigating the nature and role of transient celestial phenomena has been conducted, leaving our understanding of Indigenous astronomical knowledge grossly incomplete. This thesis is an attempt to overcome this deficiency, with a specific focus on transient celestial phenomena. My research, situated in the field of cultural astronomy, draws from the sub-disciplines of archaeoastronomy, ethnoastronomy, historical astronomy, and geomythology. This approach incorporates the methodologies and theories of disciplines in the natural sciences, social sciences, and humanities. This thesis, by publication, makes use of archaeological, ethnographic, and historical records, astronomical software packages, and geographic programs to better understand the ages of astronomical traditions and the

    Smoking prevalence continues to be significantly higher among Aboriginal people than non-Aboriginal people, resulting in a range of serious health consequences and inequities. The Aboriginal Health and Medical Research Council of New South Wales (AHandMRC) and the New South Wales (NSW) Ministry of Health (the Ministry) have worked in partnership to develop The ATRAC Framework: A Strategic Framework for Aboriginal Tobacco Resistance and Control in NSW, in collaboration with Aboriginal communities and a range of stakeholders. The goal of the ATRAC Framework is to reduce smoking prevalence and the harmful impacts of tobacco use among Aboriginal people and communities in NSW. The framework includes reviews of relevant evidence and recommended actions, organised under six areas: leadership, partnerships and coordination; community action, awareness and engagement; workforce development; supportive environments; quitting support; and evidence, evaluation and research. The framework stresses that, to be successful, Aboriginal tobacco resistance and control programs and activities need to be evidence based, coordinated, integrated and involve Aboriginal people and Aboriginal community controlled health organisations in all aspects, from development through to implementation and evaluation. Consultations and evidence reviews highlight the importance of workforce support and development, including the ongoing need for more workers specialising in Aboriginal tobacco resistance and control, as well as ongoing training for all staff involved in delivering care to Aboriginal people. Other key strategies identified in the framework include improving access to nicotine replacement therapy and other medications to support quitting; supporting, strengthening and building on existing innovative community-based programs; and further developing the evidence base. The AHandMRC and the Ministry will continue to work in partnership to drive the use of the ATRAC Framework by all people

    More undergraduate medical education programs are including curricula concerning the health, culture and history of Aboriginal people. This is in response to growing international recognition of the large divide in health status between Aboriginal and non-Aboriginal people, and the role medical education may play in achieving health equity. In this paper, we describe the development and delivery of the Aboriginal health curriculum at the Northern Ontario School of Medicine (NOSM). We describe a process for curriculum development and delivery, which includes ongoing engagement with Aboriginal communities as well as faculty expertise. Aboriginal health is delivered as a core curriculum, and learning is evaluated in summative assessments. Aboriginal health objectives are present in 4 of 5 required courses, primarily in years 1 and 2. Students attend a required 4-week Aboriginal cultural immersion placement at the end of year 1. Resources of Aboriginal knowledge are integrated into learning. In this paper, we reflect on the key challenges encountered in the development and delivery of the Aboriginal health curriculum. These include differences in Aboriginal and non-Aboriginal knowledge; risk of reinforcing stereotypes in case presentations; negotiation of curricular time; and faculty readiness and development. An organizational commitment to social accountability and the resulting community engagement model have been instrumental in creating a robust, sustainable program in Aboriginal health at NOSM.

    Background. Aboriginal Canadians face many lifestyle risk factors for hepatitis C exposure. Methods. An analysis of Ottawa Hospital Viral Hepatitis Clinic (Ottawa, Canada) patients between January 2000 and August 2013 was performed. HCV infection risk factors and HCV treatment outcomes were assessed. Socioeconomic status markers were based on area-level indicators linked to postal codes using administrative databases. Results. 55 (2.8%) Aboriginal and 1923 (97.2%) non-Aboriginal patients were evaluated. Aboriginals were younger (45.6 versus 49.6 years, p < 0.01). The distribution of gender (63.6% versus 68.3% male), HIV coinfection (9.1% versus 8.1%), advanced fibrosis stage (29.2% versus 28.0%), and SVR (56.3% versus 58.9%) was similar between groups. Aboriginals had a higher number of HCV risk factors, (mean 4.2 versus 3.1, p < 0.001) with an odds ratio of 2.5 (95% confidence interval: 1.4–4.4) for having 4+ risk factors. This was not explained after adjustment for income, social deprivation, and poor housing. Aboriginal status was not related to SVR. Aboriginals interrupted therapy more often due to loss to follow-up, poor adherence, and substance abuse (25.0% versus 4.6%). Conclusion. Aboriginal Canadians have higher levels of HCV risk factors, even when adjusting for socioeconomic markers. Despite facing greater barriers to care, SVR rates were comparable with non-Aboriginals.

    2012-05-01

    Full Text Available Abstract Introduction Long-term measures to reduce tobacco consumption in Australia have had differential effects in the population. The prevalence of smoking in Aboriginal peoples is currently more than double that of the non-Aboriginal population. Aboriginal Health Workers are responsible for providing primary health care to Aboriginal clients including smoking cessation programs. However, Aboriginal Health Workers are frequently smokers themselves, and their smoking undermines the smoking cessation services they deliver to Aboriginal clients. An understanding of the barriers to quitting smoking experienced by Aboriginal Health Workers is needed to design culturally relevant smoking cessation programs. Once smoking is reduced in Aboriginal Health Workers, they may then be able to support Aboriginal clients to quit smoking. Methods We undertook a fundamental qualitative description study underpinned by social ecological theory. The research was participatory, and academic researchers worked in partnership with personnel from the local Aboriginal health council. The barriers Aboriginal Health Workers experience in relation to quitting smoking were explored in 34 semi-structured interviews (with 23 Aboriginal Health Workers and 11 other health staff and 3 focus groups (n = 17 participants with key informants. Content analysis was performed on transcribed text and interview notes. Results Aboriginal Health Workers spoke of burdensome stress and grief which made them unable to prioritise quitting smoking. They lacked knowledge about quitting and access to culturally relevant quitting resources. Interpersonal obstacles included a social pressure to smoke, social exclusion when quitting, and few role models. In many workplaces, smoking was part of organisational culture and there were challenges to implementation of Smokefree policy. Respondents identified inadequate funding of tobacco programs and a lack of Smokefree public spaces as policy

  6. Dawes Review 5: Australian Aboriginal Astronomy and Navigation

    CERN Document Server

    Norris, Ray P

    2016-01-01

    The traditional cultures of Aboriginal Australians include a significant astronomical component, perpetuated through oral tradition, ceremony, and art. This astronomical knowledge includes a deep understanding of the motion of objects in the sky, which was used for practical purposes such as constructing calendars and for navigation. There is also evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, recorded unexpected phenomena such as eclipses and meteorite impacts, and could determine the cardinal points to an accuracy of a few degrees. Putative explanations of celestial phenomena appear throughout the oral record, suggesting traditional Aborig- inal Australians sought to understand the natural world around them, in the same way as modern scientists, but within their own cultural context. There is also a growing body of evidence for sophisticated navigational skills, including the use of astronomically based songlines. Songlines are effectively oral ...

  7. Aboriginal Determination: Native Title Claims and Barriers to Recognition

    Directory of Open Access Journals (Sweden)

    Zia Akhtar

    2011-09-01

    Full Text Available The Australian government has proposed a referendum in 2012 to decide the constitutional status of its indigenous people. There is at present no mechanism to define the indigenous people as a domestic or foreign entity of the Commonwealth. This is an important issue because other settler governments have developed a framework to implement their relationship with the native people. As a result, it is difficult prove title to land that has been abrogated by the deeds of the settlers. In Mabo v Queensland (2,the Commonwealth government was found to have breached its fiduciary duty to the Aboriginal peoples. The judgment led to the Native Title Act 1993 that established the process of asserting native rights that were held to coexist with pastoral ownership. The promulgation of the Native Title Amendment Act 1998 reversed this process and augmented the powers of non-native landlords by providing the device to extinguish native rights. In Western Australia v Ward, a mining lease was held to have precedence over native title that was adjudged to be part of a bundle of rights. In implementing the Native Title Act the issue turns on the determination of the ties to land/ sea that the government allows to the Aboriginal peoples. The judgment in Harrington-Smith on behalf of the Wongatha People v Western Australia indicates that title can be excluded on procedural grounds and that there was an incompatibility between the claims of the Aboriginal peoples and the settlers’ claims. The road map towards a more effective regime of proving title can be achieved if the Aboriginal peoples are granted recognition as a nation in the Constitution and a treaty is signed with them.

    Aboriginal approaches to the naming of places across Australia differ radically from the official introduced Anglo-Australian system. However, many of these earlier names have been incorporated into contemporary nomenclature, with considerable reinterpretations of their function and form. Recently, state jurisdictions have encouraged the adoption of a greater number of Indigenous names, sometimes alongside the accepted Anglo-Australian terms, around Sydney Harbour, for example. In some cases,...

    Full Text Available Abstract Background Streptococcus pneumoniae (Pnc, nontypeable Haemophilus influenzae (NTHi and Moraxella catarrhalis (Mcat are the most important bacterial pathogens associated with otitis media (OM. Previous studies have suggested that early upper respiratory tract (URT bacterial carriage may increase risk of subsequent OM. We investigated associations between early onset of URT bacterial carriage and subsequent diagnosis of OM in Aboriginal and non-Aboriginal children living in the Kalgoorlie-Boulder region located in a semi-arid zone of Western Australia. Methods Aboriginal and non-Aboriginal children who had nasopharyngeal aspirates collected at age 1-  Results Carriage rates of Pnc, NTHi and Mcat at age 1-  Conclusion Early NTHi carriage in Aboriginal children and Mcat in non-Aboriginal children is associated with increased risk of OM independent of environmental factors. In addition to addressing environmental risk factors for carriage such as overcrowding and exposure to environmental tobacco smoke, early administration of pneumococcal-Haemophilus influenzae D protein conjugate vaccine to reduce bacterial carriage in infants, may be beneficial for Aboriginal children; such an approach is currently being evaluated in Australia.

    In this presentation we will address the issues relating to the astronomical heritage of contemporary aboriginal groups and othe minorities. We will deal specially with the intangible astronomical heritage and their particularities. We will study (from the ethnographic experience with Aboriginal groups, Creoles and Europeans in the Argentine Chaco) the conflicts referring to the different ways, in which the native's knowledge and practice are categorized by the natives themselves, by the scientists, the state politicians, the professional artists and NGOs. We will address several cases to illustrate this kind of conflicts. We will analyze the complexities of patrimonial policies when it are applied to practices and representations of contemporary communities involved in power relations with national states and the global system. The essentialization of identities, the folklorization of representations and practices, the fossilization of aboriginal peoples are some of the risks of give the label of "cultural heritage" without a careful consideration of each specific case.In particular we will suggest possible forms by which he international scientific community could collaborate to improve the agenda of national states instead of reproducing colonial prejudices. In this way we will contribute to promote the respect for ethnic and religious minorities.

    Full Text Available Abstract Background Racism has been identified as an important determinant of health but few studies have explored associations between racism and health outcomes for Australian Aboriginal young people in urban areas. Methods Cross sectional data from participants aged 12-26 years in Wave 1 of the Victorian Aboriginal Health Service's Young People's Project were included in hierarchical logistic regression models. Overall mental health, depression and general health were all considered as outcomes with self-reported racism as the exposure, adjusting for a range of relevant confounders. Results Racism was reported by a high proportion (52.3% of participants in this study. Self-reported racism was significantly associated with poor overall mental health (OR 2.67, 95% CI 1.25-5.70, p = 0.01 and poor general health (OR 2.17, 95% CI 1.03-4.57, p = 0.04, and marginally associated with increased depression (OR 2.0; 95% CI 0.97-4.09, p = 0.06 in the multivariate models. Number of worries and number of friends were both found to be effect modifiers for the association between self-reported racism and overall mental health. Getting angry at racist remarks was found to mediate the relationship between self-reported racism and general health. Conclusions This study highlights the need to acknowledge and address racism as an important determinant of health and wellbeing for Aboriginal young people in urban areas of Australia.

  12. Australian Aboriginal Memoir and Memory: A Stolen Generations Trauma Narrative

    Directory of Open Access Journals (Sweden)

    Justine Seran

    2015-10-01

    Full Text Available This article proposes a re-reading of Aboriginal author Sally Morgan’s Stolen Generations narrative My Place (1987 in post-Apology Australia (2008–present. The novel tells the story of Morgan’s discovery of her maternal Aboriginal origins through the life-stories of her mother and grandmother; the object of a quest for the past that is both relational and matrilineal; incorporating elements of autobiography and as-told-to memoirs to create a form of choral autoethnography. Morgan’s text explores the intergenerational consequences of child removal in the Aboriginal context and is representative of Indigenous-authored narratives in its suggestion that the children and grand-children of victims of colonial policies and practices can work through the trauma of their ancestors. I examine the literary processes of decolonization of the Indigenous writing/written self and community; as well as strategies for individual survival and cultural survivance in the Australian settler colonial context; especially visible through the interactions between traumatic memories and literary memoirs, a genre neglected by trauma theory’s concern with narrative fragmentation and the proliferation of “themed” life-writing centered on a traumatic event. This article calls for a revision of trauma theory’s Eurocentrism through scholarly engagement with Indigenous experiences such as Morgan’s and her family in order to broaden definitions and take into account collective, historical, and inherited trauma.

    2014-01-01

    Tackling smoking is an integral component of efforts to improve health outcomes in Aboriginal communities. Social marketing is an effective strategy for promoting healthy attitudes and influencing behaviours; however, there is little evidence for its success in reducing smoking rates in Aboriginal communities. This paper outlines the development, implementation and evaluation of Kick the Habit Phase 2, an innovative tobacco control social marketing campaign in Aboriginal communities in New South Wales (NSW). The Aboriginal Health & Medical Research Council worked with three Aboriginal communities and a creative agency to develop locally tailored, culturally relevant social marketing campaigns. Each community determined the target audience and main messages, and identified appropriate local champions and marketing tools. Mixed methods were used to evaluate the campaign, including surveys and interviews with community members and Aboriginal Community Controlled Health Service staff. Community survey participants demonstrated high recall of smoking cessation messages, particularly for messages and images specific to the Kick the Habit campaign. Staff participating in interviews reported an increased level of interest from community members in smoking cessation programs, as well as increased confidence and skills in developing further social marketing campaigns. Aboriginal community-driven social marketing campaigns in tobacco control can build capacity, are culturally relevant and lead to high rates of recall in Aboriginal communities.

  18. Telling stories: nurses, politics and Aboriginal Australians, circa 1900-1980s.

    Science.gov (United States)

    Forsyth, Sue

    2007-02-01

    The focus of this paper is stories by, and about, (mainly non-Aboriginal) Registered Nurses working in hospitals and clinics in remote areas of Australia from the early 1900s to the 1980s as they came into contact with, or cared for, Aboriginal people. Government policies that controlled and regulated Aboriginal Australians provide the context for these stories. Memoirs and other contemporary sources reveal the ways in which government policies in different eras influenced nurse's attitudes and clinical practice in relation to Aboriginal people, and helped institutionalise racism in health care. Up until the 1970s, most nurses in this study unquestioningly accepted firstly segregation, then assimilation policies and their underlying paternalistic ideologies, and incorporated them into their practice. The quite marked politicisation of Aboriginal issues in the 1970s in Australia and the move towards self-determination for Aboriginal people politicised many - but not all - nurses. For the first time, many nurses engaged in a robust critique of government policies and what this meant for their practice and for Aboriginal health. Other nurses, however, continued as they had before - neither questioning prevailing policy nor its effects on their practice. It is argued that only by understanding and confronting the historical roots of institutional racism, and by speaking out against such practices, can discrimination and racism be abolished from nursing practice and health care. This is essential for nursing's current and future professional development and for better health for Aboriginal Australians.

    Full Text Available Objectives: To examine factors that impact on breastfeeding duration among Western Australian Aboriginal children. We hypothesised that Aboriginal children living in remote locations in Western Australia were breastfed for longer than those living in metropolitan locations. Methods: A population-based cross-sectional survey was conducted from 2000 to 2002 in urban, rural and remote settings across Western Australia. Cross-tabulations and multivariate logistic regression analyses were performed, using survey weights to produce unbiased estimates for the population of Aboriginal children. Data on demographic, maternal and infant characteristics were collected from 3932 Aboriginal birth mothers about their children aged 0–17 years (representing 22,100 Aboriginal children in Western Australia. Results: 71% of Aboriginal children were breastfed for three months or more. Accounting for other factors, there was a strong gradient for breastfeeding duration by remoteness, with Aboriginal children living in areas of moderate isolation being 3.2 times more likely to be breastfed for three months or more (p < 0.001 compared to children in metropolitan Perth. Those in areas of extreme isolation were 8.6 times more likely to be breastfed for three months or longer (p < 0.001. Conclusions: Greater residential isolation a protective factor linked to longer breastfeeding duration for Aboriginal children in our West Australian cohort.

    2014-01-01

    In Canada, the Aboriginal community is most at risk for HIV infection. Aboriginal peoples have disproportionately high rates of violence, drug use, and challenging socioeconomic circumstances. All of this is related to a history of colonization that has left Aboriginal people vulnerable to HIV infection through unsafe sex, needle sharing, and lack of access to health promotion and education. Aboriginal women are at particular risk for HIV infection. They experience a disproportionate degree of trauma, which is associated with colonization, high rates of childhood sexual abuse, and illicit drug use. A history of trauma impacts on access to health care, uptake of antiretroviral therapy, and mortality and morbidity in people with HIV. We describe the case of a 52-year-old, HIV-infected Aboriginal woman. We review the current evidence related to her case, including colonization, intersectionality, post-traumatic stress disorder, depression, revictimization, and substance use. PMID:24012166

    2007-01-01

    We analysed data from Aboriginal patients with type 2 diabetes recruited to the community-based Fremantle Diabetes Study and compared them with those from the Anglo-Celt participants. Diabetes prevalence among Aboriginal people in the Fremantle area was more than double that of Anglo-Celts and the average age at diagnosis was 14 years or younger. Glycaemic control, urinary albumin :creatinine and the proportion of smokers were all higher in the Aboriginal group and there was evidence of lower diabetes-related quality of life and high rates of disability at a young age. The Aboriginal patients died 18 years or younger than their Anglo-Celt counterparts. Specialized, culturally-sensitive and sustainable programmes are urgently needed to improve the management of diabetes in urban Aboriginal communities.

    2016-07-01

    Full Text Available Homelessness among Indigenous peoples is an important issue in Canada and internationally. Research was conducted in seven metropolitan areas in the four western provinces of Canada to explore current services with the aim of developing a best practices framework to end homelessness for Aboriginal peoples. Sequential mixed methods were used. Key results found agreement that Aboriginal peoples were overrepresented among the homeless and policy determined the approach to and comprehensiveness of services provided. Funding, lack of time, and lack of resources were highlighted as issues. Gaps identified included a lack of partnership, cross-cultural collaboration, cultural safety, and evaluation and research in service provision. Best practices included ensuring cultural safety, fostering partnerships among agencies, implementing Aboriginal governance, ensuring adequate and sustainable funding, equitable employment of Aboriginal staff, incorporating cultural reconnection, and undertaking research and evaluation to guide policy and practices related to homelessness among Aboriginal peoples.

    In this study, we attempted to explore the experiences and beliefs of Aboriginal families as they cared for their children in the first year of life. We collected family stories concerning child rearing, development, behavior, health, and well-being between each infant's birth and first birthday. We found significant differences in parenting behaviors and child-rearing practices between Aboriginal groups and mainstream Australians. Aboriginal parents perceived their children to be autonomous individuals with responsibilities toward a large family group. The children were active agents in determining their own needs, highly prized, and included in all aspects of community life. Concurrent with poverty, neocolonialism, and medical hegemony, child-led parenting styles hamper the effectiveness of health services. Hence, until the planners of Australia's health systems better understand Aboriginal knowledge systems and incorporate them into their planning, we can continue to expect the failure of government and health services among Aboriginal communities.

    The traditional concept of terraforming assumes ready availability of candidate planets with acceptable qualities: orbiting a star in its "Goldilocks zone", liquid water, enough mass, years longer than days, magnetic field, etc. But even stipulating affordable interstellar travel, we still might never find a good candidate elsewhere. Whatever we found likely would require centuries of heavy terraforming, just as Mars or Venus would here. Our increasing appreciation of the ubiquity of life suggests that any terra nova would already possess it. We would then face the dilemma of introducing alien life forms (us, our microbes) into another living world. Instead, we propose a novel method to create habitable environments for humanity by enclosing airless, sterile, otherwise useless planets, moons, and even large asteroids within engineered shells, which avoids the conundrum. These shells are subject to two opposing internal stresses: compression due to the primary's gravity, and tension from atmospheric pressure contained inside. By careful design, these two cancel each other resulting in zero net shell stress. Beneath the shell an Earth-like environment could be created similar in almost all respects to that of Home, except for gravity, regardless of the distance to the sun or other star. Englobing a small planet, moon, or even a dwarf planet like Ceres, would require astronomical amounts of material (quadrillions of tons) and energy, plus a great deal of time. It would be a quantum leap in difficulty over building Dyson Dots or industrializing our solar system, perhaps comparable to a mission across interstellar space with a living crew within their lifetime. But when accomplished, these constructs would be complete (albeit small) worlds, not merely large habitats. They could be stable across historic timescales, possibly geologic. Each would contain a full, self-sustaining ecology, which might evolve in curious directions over time. This has interesting implications

    Full Text Available Self-concept has been found to play a key role in academic and psychosocial outcomes for students. Appreciating the factors that have a bearing upon self-concept may be of particular importance for Aboriginal students, many of whom experience poorer outcomes than non-Aboriginal Canadians. The current study explored the relationships between multidimensional self-concept, perceived strengths and academic achievement among a sample Aboriginal and non-Aboriginal students. Results indicated that perceived self-concept and strengths were largely similar across groups. However, students in the two groups drew on different strengths to comprise their general self-concept. Findings are explored within the context of existing research and theory.

    Background/objectives Delayed presentation of symptomatic cancer is associated with poorer survival. Aboriginal patients with cancer have higher rates of distant metastases at diagnosis compared with non-Aboriginal Australians. This paper examined factors contributing to delayed diagnosis of cancer among Aboriginal Australians from patient and service providers' perspectives. Methods In-depth, open-ended interviews were conducted in two stages (2006–2007 and 2011). Inductive thematic analysis was assisted by use of NVivo looking around delays in presentation, diagnosis and referral for cancer. Participants Aboriginal patients with cancer/family members (n=30) and health service providers (n=62) were recruited from metropolitan Perth and six rural/remote regions of Western Australia. Results Three broad themes of factors were identified: (1) Contextual factors such as intergenerational impact of colonisation and racism and socioeconomic deprivation have negatively impacted on Aboriginal Australians' trust of the healthcare professionals; (2) health service-related factors included low accessibility to health services, long waiting periods, inadequate numbers of Aboriginal professionals and high staff turnover; (3) patient appraisal of symptoms and decision-making, fear of cancer and denial of symptoms were key reasons patients procrastinated in seeking help. Elements of shame, embarrassment, shyness of seeing the doctor, psychological ‘fear of the whole health system’, attachment to the land and ‘fear of leaving home’ for cancer treatment in metropolitan cities were other deterrents for Aboriginal people. Manifestation of masculinity and the belief that ‘health is women's domain’ emerged as a reason why Aboriginal men were reluctant to receive health checks. Conclusions Solutions to improved Aboriginal cancer outcomes include focusing on the primary care sector encouraging general practitioners to be proactive to suspicion of symptoms with appropriate

    A new compilation of pollen and packrat midden data from western North America provides a refined reconstruction of the composition and distribution of biomes in western North America for today and for 6000 and 18,000 radiocarbon years before present (14C yr BP). Modern biomes in western North America are adequately portrayed by pollen assemblages from lakes and bogs. Forest biomes in western North America share many taxa in their pollen spectra and it can be difficult to discriminate among these biomes. Plant macrofossils from packrat middens provide reliable identification of modern biomes from arid and semiarid regions, and this may also be true in similar environments in other parts of the world. However, a weighting factor for trees and shrubs must be used to reliably reconstruct modern biomes from plant macrofossils. A new biome, open conifer woodland, which includes eurythermic conifers and steppe plants, was defined to categorize much of the current and past vegetation of the semiarid interior of western North America. At 6000 14C yr BP, the forest biomes of the coastal Pacific North-west and the desert biomes of the South-west were in near-modern positions. Biomes in the interior Pacific North-west differed from those of today in that taiga prevailed in modern cool/cold mixed forests. Steppe was present in areas occupied today by open conifer woodland in the northern Great Basin, while in the central and southern Rocky Mountains forests grew where steppe grows today. During the mid-Holocene, cool conifer forests were expanded in the Rocky Mountains (relative to today) but contracted in the Sierra Nevada. These differences from the forests of today imply different climatic histories in these two regions between 6000 14C yr BP and today. At 18,000 14C yr BP, deserts were absent from the South-west and the coverage of open conifer woodland was greatly expanded relative to today. Steppe and tundra were present in much of the region now covered by forests in

  17. “No More Boomerang”: Environment and Technology in Contemporary Aboriginal Australian Poetry

    Directory of Open Access Journals (Sweden)

    John Charles Ryan

    2015-12-01

    Full Text Available Based in oral traditions and song cycles, contemporary Aboriginal Australian poetry is full of allusions to the environment. Not merely a physical backdrop for human activities, the ancient Aboriginal landscape is a nexus of ecological, spiritual, material, and more-than-human overlays—and one which is increasingly compromised by modern technological impositions. In literary studies, while Aboriginal poetry has become the subject of critical interest, few studies have foregrounded the interconnections between environment and technology. Instead, scholarship tends to focus on the socio-political and cultural dimensions of the writing. How have contemporary Australian Aboriginal poets responded to the impacts of environmental change and degradation? How have poets addressed the effects of modern technology in ancestral environments, or country? This article will develop an ecocritical and technology-focused perspective on contemporary Aboriginal poetry through an analysis of the writings of three significant literary-activists: Jack Davis (1917–2000, Oodgeroo Noonuccal (1920–1993, and Lionel Fogarty (born 1958. Davis, Noonuccal, and Fogarty strive poetically to draw critical attention to the particular impacts of late modernist technologies on Aboriginal people and country. In developing a critique of invasive technologies that adversely affect the environment and culture, their poetry also invokes the Aboriginal technologies that sustained (and, in places, still sustain people in reciprocal relation to country.

    Full Text Available Shaun C Ewen,1 David Hollinsworth2 1Melbourne Poche Centre for Indigenous Health, Faculty of Medicine, Dentistry and Health Sciences, The University of Melbourne, Melbourne, VIC, 2Indigenous Studies, Faculty of Arts, Business and Law, University of the Sunshine Coast, Sippy Downs, QLD, Australia Introduction: Attention to Aboriginal health has become mandatory in Australian medical education. In parallel, clinical management has increasingly used Aboriginality as an identifier in both decision making and reporting of morbidity and mortality. This focus is applauded in light of the gross inequalities in health outcomes between indigenous people and other Australians. Methods: A purposive survey of relevant Australian and international literature was conducted to map the current state of play and identify concerns with efforts to teach cultural competence with Aboriginal people in medical schools and to provide “culturally appropriate” clinical care. The authors critically analyzed this literature in light of their experiences in teaching Aboriginal studies over six decades in many universities to generate examples of iatrogenic effects and possible responses. Results and discussion: Understanding how to most effectively embed Aboriginal content and perspectives in curriculum and how to best teach and assess these remains contested. This review canvasses these debates, arguing that well-intentioned efforts in medical education and clinical management can have iatrogenic impacts. Given the long history of racialization of Aboriginal people in Australian medicine and the relatively low levels of routine contact with Aboriginal people among students and clinicians, the review urges caution in compounding these iatrogenic effects and proposes strategies to combat or reduce them. Conclusion: Long overdue efforts to recognize gaps and inadequacies in medical education about Aboriginal people and their health and to provide equitable health services

  19. Repositioning the Racial Gaze: Aboriginal Perspectives on Race, Race Relations and Governance

    Full Text Available In Australia, public debate about recognition of the nation’s First Australians through constitutional change has highlighted the complexity and sensitivities surrounding Indigenous/state relations at even the most basic level of legal rights. But the unevenness of race relations has meant Aboriginal perspectives on race relations are not well known. This is an obstacle for reconciliation which, by definition, must be a reciprocal process. It is especially problematic in regions with substantial Aboriginal populations, where Indigenous visibility make race relations a matter of everyday experience and discussion. There has been considerable research on how settler Australians view Aboriginal people but little is known about how Aboriginal people view settler Australians or mainstream institutions. This paper presents the findings from an Australian Research Council project undertaken in partnership with Larrakia Nation Aboriginal Corporation. Drawing on in-depth interviews with a cross-section of Darwin’s Aboriginal residents and visitors, it aims to reverse the racial gaze by investigating how respondents view settler Australian politics, values, priorities and lifestyles. Through interviews with Aboriginal people this research provides a basis for settler Australians to discover how they are viewed from an Aboriginal perspective. It repositions the normativity of settler Australian culture, a prerequisite for a truly multicultural society. Our analysis argues the narratives of the participants produce a story of Aboriginal rejection of the White Australian neo-liberal deal of individual advancement through economic pathways of employment and hyper-consumption. The findings support Honneth’s arguments about the importance of intersubjective recognition by pointing to the way misrecognition creates and reinforces social exclusion.

    Takesue, R.K.; VanGeen, A.

    2004-01-01

    This study explores the potential of intertidal Protothaca staminea shells as high-resolution geochemical archives of environmental change in a coastal upwelling region. Mg/Ca and Sr/Ca ratios were analyzed by excimer laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS) at sub-weekly temporal resolution in shells growing ???1 mm per month. Growth patterns of a modern P. staminea shell from Humboldt Bay, California, collected in December 1999 made it possible to infer a lifespan from 1993 to 1998. Growth hiatuses in the shell may have excluded records of extreme events. Mg/Ca ratios appeared to be partly controlled by water temperature; the correlation coefficient between temperature and Mg/Ca was r = 0.71 in one of four growth increments. Significant year-to-year differences in the sensitivity of Mg/Ca to temperature in P. staminea could not be explained, however. Sr/Ca ratios appeared to be more closely related to shell growth rate. Oxygen isotopes, measured at 2-week temporal resolution in the same shell, did not show a clear relation to local temperature in summer, possibly because temperatures were higher and less variable at the King Salmon mudflat, where the shell was collected, than in the main channel of Humboldt Bay, where water properties were monitored. Negative shell ??13C values (upwelling events. The Mg contents of P. staminea midden shells dated to ???3 ka and ???9 ka were significantly lower than in the modern shell. This may have resulted from degradation of a Mg-rich shell organic matrix and precluded quantitative interpretation of the older high-resolution records. Elevated ??13C values in the ???3 ka shell suggested that the individual grew in highly productive or stratified environment, such as a shallow coastal embayment or lagoon.

    Full Text Available The purpose of this study was to determine whether there is a growing inequity in tobacco use, susceptibility to future smoking, and quit attempts among Off-Reserve Aboriginal (ORA youth in Canada relative to Non-Aboriginal youth. Current smoking, susceptibility to future smoking and quit attempts were examined among a nationally representative sample of ORA and Non-Aboriginal Canadian youth. Data are from cross-sectional surveys of 88,661 respondents in Grades 6 to 9 across the 2004, 2006 and 2008 survey waves of the Youth Smoking Survey (YSS. At each wave, ORA youth were more likely to be current smokers (overall OR = 3.91, 95% CI 3.47 to 4.41, to be susceptible to future smoking (overall OR = 1.37, 95% CI 1.27 to 1.48, and less likely to have ever made a quit attempt compared to Non-Aboriginal youth (overall OR = 0.74, 95% CI 0.57 to 0.96. Although susceptibility to future smoking declined for Non-Aboriginal youth, the prevalence of susceptibility remained stable among ORA youth. The percentage of ORA youth reporting making a quit attempt increased, however, current smoking rates among ORA youth did not decline. These findings suggest that the disparity in susceptibility to future tobacco use among ORA and Non-Aboriginal youth has increased over time. Despite increased rates of quit attempts, current smoking rates remain significantly higher among ORA youth. Tobacco control programs for Aboriginal youth should be a public health priority.

    This study assessed links between racism and oral health outcomes among pregnant Canadian Aboriginal women. Baseline data were analyzed for 541 First Nations (94.6%) and Métis (5.4%) women in an early childhood caries preventive trial conducted in urban and on-reserve communities in Ontario and Manitoba. One-third of participants experienced racism in the past year determined by the Measure of Indigenous Racism Experience. In logistic regressions, outcomes significantly associated with incidents of racism included: wearing dentures, off-reserve dental care, asked to pay for dental services, perceived need for preventive care, flossing more than once daily, having fewer than 21 natural teeth, fear of going to dentist, never received orthodontic treatment and perceived impact of oral conditions on quality of life. In the context of dental care, racism experienced by Aboriginal women can be a barrier to accessing services. Programs and policies should address racism's insidious effects on both mothers' and children's oral health outcomes. PMID:26853210

  3. Socio-economic impacts between the nuclear industry and Aboriginal people

    International Nuclear Information System (INIS)

    The paper explores several aspects of the socio-economic impact of the nuclear industry on Aboriginal people in northern Canada. The issues discussed include decision-making by consensus, community-based development, the role of Traditional Ecological Knowledge and Management Systems (TEKMS), relationships with land and nature, and social and health issues. The issues are discussed with respect to the divergence between Aboriginal and non-Aboriginal cultures, which affect the timelines for project viability as well as the continued harmony between industry and community. It is concluded that economic gains can be achieved through continuous community dialogue from the moment of project inception. (author)

    2011-03-01

    The Determinants of TB Transmission (DTT) project, a federally-funded study covering the period April 1, 2006-March 31, 2013, and examining the determinants of TB transmission amongst the Canadian-born population (Aboriginal and non-Aboriginal) in the prairie provinces of Canada, took a novel approach to health research involving Aboriginal people. The methodology aligned itself with the recently published Canadian Institutes of Health Research (CIHR) Guidelines for Health Research Involving Aboriginal People and the established principles of Ownership, Control, Access, and Possession (OCAP). This article details the process by which collaboration with Aboriginal peoples was achieved, including the involvement of Aboriginal researchers, the development of Provincial Network Committees (PNCs), and communications with First Nations Chiefs and Council. Strengths of this methodology included Aboriginal organizational and community support with a high rate of participation; PNC leadership, which brought together Aboriginal stakeholders with provincial and federal TB program planners; and the exploration of both on and off-reserve transmission factors. Challenges of the methodology included meeting funding agency timelines and expectations given the gradual process of trust development and PNC-reviewed publication; respecting both community and individual participants' autonomy regarding study participation; and political discomfort with strong Aboriginal involvement. While the methodology required a dedicated investment from researchers and funding agencies alike, the process was worthwhile and achieved a high degree of support from its major collaborators: the Aboriginal peoples.

    Asthma and allergies are common conditions among Aboriginal children and adolescents. The purpose of this study was to assess the health and health-care inequities experienced by affected children and by their parents. Aboriginal research assistants conducted individual interviews with 46 Aboriginal children and adolescents who had asthma and/or allergies (26 First Nations, 19 Métis, 1 Inuit) and 51 parents or guardians of these children and adolescents. Followup group interviews were conducted with 16 adolescents and 25 parents/ guardians. Participants reported inadequate educational resources, environmental vulnerability, social and cultural pressures, exclusion, isolation, stigma, blame, and major support deficits. They also described barriers to health-service access, inadequate health care, disrespectful treatment and discrimination by health-care providers, and deficient health insurance. These children, adolescents, and parents recommended the establishment of culturally appropriate support and education programs delivered by Aboriginal peers and health professionals. PMID:24236369

    Full Text Available The on-line project A History of Aboriginal Sydney, based at the University of Sydney, takes existing educational and Australian Indigenous digital initiatives in a new direction. By dividing Sydney into six geographical areas, we are creating a knowledge base of post-invasion Aboriginal history, incorporating different forms of tagging, timeline and digital mapping to provide multiple paths to information in text, videos, still images and, in the future, three dimensional reconstructions of former living areas. After eighteen months research we are maintaining a balance between unearthing new and forgotten material, incorporating it into our developing database, and exploring the potential of digital mapping, animation and 3D historical reconstruction for educational and research purposes. With close Indigenous consultation, especially the Aboriginal Educational Consultative Groups, we hope to digitally construct the Aboriginal history of Sydney and return it to the people who have been deprived of so much of their history for so long.

    Little is known about risk factors for problem gambling (PG) within the rapidly growing urban Aboriginal population in North America. Racial discrimination may be an important risk factor for PG given documented associations between racism and other forms of addictive behaviour. This study examined associations between racial discrimination and problem gambling among urban Aboriginal adults, and the extent to which this link was mediated by post traumatic stress. Data were collected via in-person surveys with a community-based sample of Aboriginal adults living in a mid-sized city in western Canada (N = 381) in 2010. Results indicate more than 80 % of respondents experienced discrimination due to Aboriginal race in the past year, with the majority reporting high levels of racism in that time period. Past year racial discrimination was a risk factor for 12-month problem gambling, gambling to escape, and post traumatic stress disorder (PTSD) symptoms in bootstrapped regression models adjusted for confounders and other forms of social trauma. Elevated PTSD symptoms among those experiencing high levels of racism partially explained the association between racism and the use of gambling to escape in statistical models. These findings are the first to suggest racial discrimination may be an important social determinant of problem gambling for Aboriginal peoples. Gambling may be a coping response that some Aboriginal adults use to escape the negative emotions associated with racist experiences. Results support the development of policies to reduce racism directed at Aboriginal peoples in urban areas, and enhanced services to help Aboriginal peoples cope with racist events.

    2014-09-01

    There is evidence that Aboriginal children and youth in Canada and elsewhere are at higher risk of obesity and overweight than other children. However, there has been no review of healthy weights interventions specifically aimed at Aboriginal children. A structured search for peer-reviewed articles presenting and evaluating healthy weights interventions for Aboriginal children and youth was conducted. Seventeen articles, representing seven interventions, were reviewed to identify their main characteristics, evaluation design, and evaluation outcomes. Interventions included several large community-based programs as well as several more focused programs that all targeted First Nations or American Indians, rather than Métis or Inuit. Only 1 program served an urban Aboriginal population. None of the published evaluations reported significant reductions in obesity or overweight or sustained increases in physical activity, although some evaluations presented evidence of positive effects on children's diets or on nutrition knowledge or intentions. We conclude that broader structural factors affecting the health of Aboriginal children may limit the effectiveness of these interventions, and that more evidence is required regarding interventions for Aboriginal children in various geographic and cultural contexts in Canada including Inuit and Métis communities.

    Illicit and prescription drug use disorders are two to four times more prevalent among Aboriginal peoples in North America than the general population. Research suggests Aboriginal cultural participation may be protective against substance use problems in rural and remote Aboriginal communities. As Aboriginal peoples continue to urbanize rapidly around the globe, the role traditional Aboriginal beliefs and practices may play in reducing or even preventing substance use problems in cities is becoming increasingly relevant, and is the focus of the present study. Mainstream acculturation was also examined. Data were collected via in-person surveys with a community-based sample of Aboriginal adults living in a mid-sized city in western Canada (N = 381) in 2010. Associations were analysed using two sets of bootstrapped linear regression models adjusted for confounders with continuous illicit and prescription drug problem scores as outcomes. Psychological mechanisms that may explain why traditional culture is protective for Aboriginal peoples were examined using the cross-products of coefficients mediation method. The extent to which culture served as a resilience factor was examined via interaction testing. Results indicate Aboriginal enculturation was a protective factor associated with reduced 12-month illicit drug problems and 12-month prescription drug problems among Aboriginal adults in an urban setting. Increased self-esteem partially explained why cultural participation was protective. Cultural participation also promoted resilience by reducing the effects of high school incompletion on drug problems. In contrast, mainstream acculturation was not associated with illicit drug problems and served as a risk factor for prescription drug problems in this urban sample. Findings encourage the growth of programs and services that support Aboriginal peoples who strive to maintain their cultural traditions within cities, and further studies that examine how Aboriginal

    We explored with Aboriginal adults living in a remote Australian community the social context of food choice and factors perceived to shape food choice. An ethnographic approach of prolonged community engagement over 3 years was augmented by interviews. Our findings revealed that knowledge, health, and resources supporting food choice were considered "out of balance," and this imbalance was seen to manifest in a Western-imposed diet lacking variety and overrelying on familiar staples. Participants felt ill-equipped to emulate the traditional pattern of knowledge transfer through passing food-related wisdom to younger generations. The traditional food system was considered key to providing the framework for learning about the contemporary food environment. Practitioners seeking to improve diet and health outcomes for this population should attend to past and present contexts of food in nutrition education, support the educative role of caregivers, address the high cost of food, and support access to traditional foods.

  8. Reanimating Lost Landscapes: Bringing Visualisation to Aboriginal History

    2010-12-01

    Full Text Available In Public History Review volume 11, Peter Osborne called for the methodologies of environmental history to be brought more securely and more imaginatively into public history. Environmental history by its own definition, he argued, encompassed Indigenous, ethnic and Anglo-Celtic histories, and heritages natural and built, material and intangible. I believe too that we public historians need to Incorporate changing landscapes and topographies as a vital element in understanding why communities and their built heritages constantly transfigure. Sometimes a single geographic factor such as the northern Gulf Stream can go far to explain the spectacular rise of a small island like Great Britain to world power. Equally we can help to explain the precipitous decline of towns like Bourke by degradation and siltation in the Darling River. This paper uses the case study of the Narrabeen town camp to explore the potential of digital visual technologies in Aboriginal History.

  9. The Study of Environment on Aboriginal Resilience and Child Health (SEARCH: study protocol

    2010-05-01

    Full Text Available Abstract Background Aboriginal Australians have a life expectancy more than ten years less than that of non-Aboriginal Australians, reflecting their disproportionate burden of both communicable and non-communicable disease throughout the lifespan. Little is known about the health and health trajectories of Aboriginal children and, although the majority of Aboriginal people live in urban areas, data are particularly sparse in relation to children living in urban areas. Methods/Design The Study of Environment on Aboriginal Resilience and Child Health (SEARCH is a cohort study of Aboriginal children aged 0-17 years, from urban and large regional centers in New South Wales, Australia. SEARCH focuses on Aboriginal community identified health priorities of: injury; otitis media; vaccine-preventable conditions; mental health problems; developmental delay; obesity; and risk factors for chronic disease. Parents/caregivers and their children are invited to participate in SEARCH at the time of presentation to one of the four participating Aboriginal Community Controlled Health Organisations at Mount Druitt, Campbelltown, Wagga Wagga and Newcastle. Questionnaire data are obtained from parents/caregivers and children, along with signed permission for follow-up through repeat data collection and data linkage. All children have their height, weight, waist circumference and blood pressure measured and complete audiometry, otoscopy/pneumatic otoscopy and tympanometry. Children aged 1-7 years have speech and language assessed and their parents/caregivers complete the Parental Evaluation of Developmental Status. The Study aims to recruit 1700 children by the end of 2010 and to secure resources for long term follow up. From November 2008 to March 2010, 1010 children had joined the study. From those 446 children with complete data entry, participating children ranged in age from 2 weeks to 17 years old, with 144 aged 0-3, 147 aged 4-7, 75 aged 8-10 and 79 aged 11

    Objectives The aims of the present study were to: (1) describe the health status and health indicators for urban Aboriginal children (age 0-16 years) in south-east Sydney; and (2) evaluate the quality of routinely collected clinical data and its usefulness in monitoring local progress of health outcomes. Methods Aboriginal maternal and child health routine data, from multiple databases, for individuals accessing maternal and child health services between January 2007 and December 2012 were examined and compared with state and national health indicators. Results Reductions in maternal smoking, premature delivery and low birthweight delivery rates were achieved in some years, but no consistent trends emerged. Paediatric services had increased referrals each year. The most frequent diagnoses were nutritional problems, language delay or disorder and developmental delay or learning difficulties. Twenty per cent of children had a chronic medical condition requiring long-term follow-up. Aboriginal children were more likely to be discharged from hospital against medical advice than non-Aboriginal children. Routinely collected data did not include some information essential to monitor determinants of health and health outcomes. Conclusions Aboriginal children living in this urban setting had high levels of need. Routinely recorded data were suboptimal for monitoring local health status and needed to reflect national and state health indicators. Routinely collected data can identify service gaps and guide service development. What is known about this topic? Despite improvements in some areas, there continue to be significant gaps in maternal and child health outcomes between Aboriginal and non-Aboriginal Australians. These are poorly documented at a local service level. What does this paper add? Intensive, local services offered to Aboriginal women and children can result in rapid service engagement. Health service data routinely collected by local services can be used to

The aim of the present study was to improve understanding about Victorian Aboriginal people and mental health service patterns. We located four mental health administrative datasets to analyse descriptively, including Practice Health Atlas, Alcohol and Other Drug Treatment Service (AODTS), Kids Helpline and Close The Gap Pharmaceutical Scheme data. A large proportion of the local Aboriginal population (70%) were regular ACCHO clients; of these, 21% had a mental health diagnosis and, of these, 23% had a Medicare Mental Health Care Plan (MHCP). There were higher rates of Medicare MHCP completion rates where general practitioners (GPs) had mental health training and the local Area Mental Health Service had a Koori Mental Health Liaison Officer. There was an over-representation of AODTS episodes, and referrals for these episodes were more likely to come through community, corrections and justice services than for non-Aboriginal people. Aboriginal episodes were less likely to have been referred by a GP or police and less likely to have been referrals to community-based or home-based treatment. There was an over-representation of Victorian Aboriginal calls to Kids Helpline, and these were frequently for suicide and self-harm reasons. We recommend primary care mental health programs include quality audits, GP training, non-pharmaceutical options and partnerships. Access to appropriate AODTS is needed, particularly given links to high incarcerations rates. To ensure access to mental health services, improved understanding of mental health service participation and outcomes, including suicide prevention services for young people, is needed.

    Objectives Australian Aboriginal people have at least eight times the incidence of end-stage kidney disease, requiring dialysis, as the non-Aboriginal population. Provision of health services to rural Aboriginal people with renal disease is challenging due to barriers to access and cultural differences. We aimed to describe the experiences of Aboriginal people receiving haemodialysis in rural Australia, to inform strategies for improving renal services. Design A qualitative design incorporating: Indigenist research methodology and Community Based Participatory Research principles. In-depth interviews used a ‘yarning’ and storytelling approach. Thematic analysis was undertaken and verified by an Aboriginal Community Reference Group. Setting A health district in rural New South Wales, Australia. Participants Snowball sampling recruited 18 Aboriginal haemodialysis recipients. Results Six themes emerged which described the patient journey: ‘The biggest shock of me life,’ expressed the shock of diagnosis and starting the dialysis; ‘Beats the alternative but it messes up your life,’ explained how positive attitudes to treatment develop; ‘Family is everything’, described the motivation and support to continue dialysis; ‘If I had one of them nurses at home to help me’, depicted acute hospital settings as culturally unsafe; ‘Don't use them big jawbreakers’, urged service providers to use simple language and cultural awareness; ‘Stop ‘em following us onto the machine’, emphasised the desire for education for the younger generations about preventing kidney disease. An Aboriginal interpretation of this experience, linked to the analysis, was depicted in the form of an Aboriginal painting. Conclusions Family enables Aboriginal people to endure haemodialysis. Patients believe that priorities for improving services include family-centred and culturally accommodating healthcare systems; and improving access to early screening of kidney disease

  14. Forest carbon trading : legal, policy, ecological and aboriginal issues

    International Nuclear Information System (INIS)

    Canada's forest ecosystems store 88 billion tonnes of carbon, with trees alone storing 13 billion tonnes, twice the global annual carbon emissions. Carbon trading could affect forest management. Certain types of forest carbon project will offer cost-effective carbon sequestration options. This paper addresses current concerns about forest carbon trading such as phony carbon gains, biodiversity impact and increased fossil fuel emissions. Statistics were presented with information on global carbon stocks. The Kyoto Protocol requires that Canada must count all changes in forest carbon stocks resulting from afforestation, reforestation or deforestation, and that Canada has the option of counting carbon stock changes from forest management. The decision must be made by 2006, and considerations are whether to present projected net source or sink, or whether to count current commercially managed areas or all timber productive areas. An outline of federal constitutional authority power regarding Kyoto was presented, including limits and risks of trade and treaty powers. The economics of forest carbon were outlined with reference to increasing forest carbon storage. A two-pronged approach was advised, with avoided logging and plantation and intensive management securing carbon and timber benefits. Examples of pre-Kyoto pilots were presented, including the SaskPower project, the Little Red River Cree project and the Labrador Innu project. The disadvantages of offset trading were presented. It was concluded that forest carbon markets are part of a larger vision for sustainable development in Canada's north, especially for aboriginal peoples, and may indicate a growing market for ecological services. Constitutional limits to federal power to regulate carbon trading are not insurmountable, but require care. Ownerships of forest carbon rights raises important policy and legal issues, including aboriginal right, efficiency and equity. An estimated cost of forest carbon projects

    2009-12-01

    Full Text Available The Dampier Rock Art Precinct contains the largest and most ancient collection of Aboriginal rock art in Australia. The cultural landscape created by generations of Aboriginal people includes images of long-extinct fauna and demonstrates the response of peoples to a changing climate over thousands of years as well as the continuity of lived experience. Despite Australian national heritage listing in 2007, this cultural landscape continues to be threatened by industrial development. Rock art on the eastern side of the archipelago, on the Burrup Peninsula, was relocated following the discovery of adjacent off-shore gas reserves so that a major gas plant could be constructed. Work has now begun on the construction of a second major gas plant nearby. This article describes the rock art of the Dampier Archipelago and the troubled history of European-Aboriginal contact history, before examining the impact of industry on the region and its environment. The destruction of Aboriginal rock art to meet the needs of industry is an example of continuing indifference to Aboriginal culture. While the complex struggle to protect the cultural landscape of the Burrup, in particular, involving Indigenous people, archaeologists, historians, state and federal politicians, government bureaucrats and multi-national companies, eventually led to national heritage listing, it is not clear that the battle to save the Burrup has been won.

    Full Text Available Aboriginal people across Australia suffer significant health inequalities compared with the non-Indigenous population. Evidence indicates that inroads can be made to reduce these inequalities by better understanding social and cultural determinants of health, applying holistic notions of health and developing less rigid definitions of wellbeing. The following article draws on qualitative research on Victorian Aboriginal peoples’ relationship to their traditional land (known as Country and its link to wellbeing, in an attempt to tackle this. Concepts of wellbeing, Country and nature have also been reviewed to gain an understanding of this relationship. An exploratory framework has been developed to understand this phenomenon focusing on positive (e.g., ancestry and partnerships and negative (e.g., destruction of Country and racism factors contributing to Aboriginal peoples’ health. The outcome is an explanation of how Country is a fundamental component of Aboriginal Victorian peoples’ wellbeing and the framework articulates the forces that impact positively and negatively on this duality. This review is critical to improving not only Aboriginal peoples’ health but also the capacity of all humanity to deal with environmental issues like disconnection from nature and urbanisation.

    Full Text Available There is a paucity of research on spontaneous recovery (SR from substance abuse in general, and specific to Aboriginal peoples. There is also limited understanding of the healing process associated with SR. In this study, SR was examined among a group of Aboriginal peoples in Canada. Employing a decolonizing methodology, thematic analysis of traditional talking circle narratives identified an association between a traumatic life event and an ‘awakening.’ This ‘awakening’ was embedded in primary (i.e., consider impact on personal well-being and secondary (i.e., implement alternative coping mechanism cognitive appraisal processes and intrinsic and extrinsic motivation rooted in increased traditional Aboriginal cultural awareness and understanding. This contributed to both abstinence (i.e., recovery and sustained well-being (i.e.,continued abstinence. Three key interrelated ‘themes’ specific to the role of culture in SR and recovery maintenance were identified: Aboriginal identity, cultural practices, and traditional values. These findings,combined with the limited literature, were developed into a prospective model of SR from substance abuse inAboriginal peoples. This model highlights the potential need for substance abuse treatment and intervention policy to consider culture as a determinant of health and well-being.

    Full Text Available In 2012, the remote Aboriginal community of Wilcannia in western NSW hosted the first Australian pilot of a Cuban mass adult literacy campaign model known as Yes I Can. The aim was to investigate the appropriateness of this model in Aboriginal Australia. Building on an intensive community development process of ‘socialisation and mobilisation’, sixteen community members with very low literacy graduated from the basic literacy course, with the majority continuing on into post-literacy activities, further training and/or employment. The pilot was initiated by the National Aboriginal Adult Literacy Campaign Steering Committee (NAALCSC consisting of Aboriginal leaders from the education and health sectors, and managed by the University of New England (UNE, working in partnership with the Wilcannia Local Aboriginal Land Council as the local lead agency. The pilot was supported by a Cuban academic who came to Australia for this purpose, and included a Participatory Action Research (PAR evaluation led by the UNE Project Manager. In this paper, members of the project team and the NAALCSC describe the pilot and reflect on its outcomes.

    Social capital has been linked to physical and mental health. While definitions of social capital vary, all include networks of social relationships and refer to the subsequent benefits and disadvantages accrued to members. Research on social capital for Aboriginal Australians has mainly focused on discrete rural and remote Aboriginal contexts with less known about the features and health and other benefits of social capital in urban settings. This paper presents findings from in-depth interviews with 153 Aboriginal people living in urban areas on their experiences of social capital. Of particular interest was how engagement in bonding and bridging networks influenced health and wellbeing. Employing Bourdieu's relational theory of capital where resources are unequally distributed and reproduced in society we found that patterns of social capital are strongly associated with economic, social and cultural position which in turn reflects the historical experiences of dispossession and disadvantage experienced by Aboriginal Australians. Social capital was also found to both reinforce and influence Aboriginal cultural identity, and had both positive and negative impacts on health and wellbeing. PMID:24161085

  1. Social Exclusion/Inclusion for Urban Aboriginal and Torres Strait Islander People

    2016-02-01

    Full Text Available Social exclusion social inclusion are useful concepts for making sense of the deeply embedded socio-economic disadvantaged position of Aboriginal and Torres Islander people in Australian. The concepts not only describe exclusion from social and economic participation; but seek to understand the dynamic processes behind their creation and reproduction. Yet few Australian studies go beyond describing Aboriginal over-representation on social exclusion indicators. Neither do they address the translatability of the concepts from non-Indigenous to Indigenous contexts despite mainstream studies finding the pattern of social exclusion (and therefore what social inclusion might look like differs for Aboriginal and Torres Strait Islander people to that of other disadvantaged groups. This paper uses data from the Longitudinal Study of Indigenous children to explore patterns of social exclusion across social, economic, well-being and community dimensions for urban Aboriginal and Torres Strait families. The paper then develops a contextual understanding of the processes and patterns that create and sustain social exclusion and the opportunities and challenges of moving to greater social inclusion for urban Aboriginal and Torres Strait Islander people/s.

    2012-01-01

    Full Text Available Only a few studies have investigated asthma morbidity in Canadian Aboriginal children. In the present study, data from the 2006 Aboriginal Peoples Survey were used to determine the prevalence and risk factors for asthma in Canadian Aboriginal children six to 14 years of age and adults 15 to 64 years of age living off reserve. The prevalence of asthma was 14.3% in children and 14.0% in adults. Children and adults with Inuit ancestry had a significantly lower prevalence of asthma than those with North American Indian and Métis ancestries. Factors significantly associated with ever asthma in children included male sex, allergy, low birth weight, obesity, poor dwelling conditions and urban residence. In adults, factors associated with ever asthma varied among Aboriginal groups; however, age group, sex and urban residence were associated with ever asthma in all four Aboriginal groups. The prevalence of asthma was lower in Aboriginal children and higher in Aboriginal adults compared with that reported for the Canadian population. Variation in the prevalence of and risk factors for asthma among Aboriginal ancestry groups may be related to genetic and environmental factors that require further investigation.

    Full Text Available The aim of this work was to determine the feasibility of improving Aboriginal and Torres Strait Islander status recording for notifiable diseases using all Invasive Pneumococcal Disease (IPD notifications in a regional area of New South Wales, Australia.In Australia people with IPD are nearly always admitted to hospital and their Aboriginal and Torres Strait Islander status is recorded. Aboriginal and Torres Strait Islander status was determined for IPD notifications by referring to the routine hospital admission data, in a regional area of New South Wales, Australia.There were 234 notifications in the regional area of Hunter New England during the period 2007–2009. Initially, 168 (72% notifications had Aboriginal and Torres Strait Islander status recorded. After referring to the routine hospital admission data the recorded status increased to 232 (99%. Updating the surveillance data required less than five minutes per notification.Referring to routine hospital admission data proved a useful and time-efficient surveillance strategy to increase the proportion of notifications with Aboriginal and Torres Strait Islander status. These data can then be used to better understand the current epidemiology of IPD. Aboriginal and Torres Strait Islander children aged 0–4 years have a two- to threefold higher rate of invasive pneumococcal disease than non-Aboriginal children, thus high levels of timely pneumococcal immunization coverage remain important for young Aboriginal and Torres Strait Islander children.

    The full potential for research to improve Aboriginal health has not yet been realised. This paper describes an established long-term action partnership between Aboriginal Community Controlled Health Services (ACCHSs), the Aboriginal Health and Medical Research Council of New South Wales (AH&MRC), researchers and the Sax Institute, which is committed to using high-quality data to bring about health improvements through better services, policies and programs. The ACCHSs, in particular, have ensured that the driving purpose of the research conducted is to stimulate action to improve health for urban Aboriginal children and their families. This partnership established a cohort study of 1600 urban Aboriginal children and their caregivers, known as SEARCH (the Study of Environment on Aboriginal Resilience and Child Health), which is now having significant impacts on health, services and programs for urban Aboriginal children and their families. This paper describes some examples of the impacts of SEARCH, and reflects on the ways of working that have enabled these changes to occur, such as strong governance, a focus on improved health, AH&MRC and ACCHS leadership, and strategies to support the ACCHS use of data and to build Aboriginal capacity.

    Full Text Available This paper tries to review and reassess the tribal situation with special reference to the tribal women in India and Australia. It is an attempt to locate the ‘Aboriginal woman’ question in the context of women’s movement in both countries. In Australia the women’s movement, on the whole, has not been successful in incorporating Aboriginal women into its concerns and activities. Relations with Aboriginal women have constituted a problem with the women’s movement. Despite many differences in socio-cultural set up the stories of Anil Gharai and those of Australian Aboriginal writers share many common traits and cut across cultural differences. It establishes the theory of pan-aboriginality that exists in countries that possess a sizeable population of indigenous people.

    Chronic kidney disease has a higher prevalence in Indigenous populations globally. The incidence of end-stage kidney disease in Australian Aboriginal people is eight times higher than non-Aboriginal Australians. Providing services to rural and remote Aboriginal people with chronic disease is challenging because of access and cultural differences. This study aims to describe and analyze the perspectives of Aboriginal patients' and health care providers' experience of renal services, to inform service improvement for rural Aboriginal hemodialysis patients. We conducted a thematic analysis of interviews with Aboriginal patients (n = 18) receiving hemodialysis in rural Australia and health care providers involved in their care (n = 29). An overarching theme of avoiding the "costly" crisis encompassed four subthemes: (1) Engaging patients earlier (prevent late diagnosis, slow disease progression); (2) flexible family-focused care (early engagement of family, flexibility to facilitate family and cultural obligations); (3) managing fear of mainstream services (originating in family dialysis experiences and previous racism when engaging with government organizations); (4) service provision shaped by culture (increased home dialysis, Aboriginal support and Aboriginal-led cultural education). Patients and health care providers believe service redesign is required to meet the needs of Aboriginal hemodialysis patients. Participants identified early screening and improving the relationship of Aboriginal people with health systems would reduce crisis entry to hemodialysis. These strategies alongside improving the cultural competence of staff would reduce patients' fear of mainstream services, decrease the current emotional and family costs of care, and increase efficiency of health expenditure on a challenging and increasingly unsustainable treatment system.

    Bullying among youth is rampant and research suggests that young Aboriginal women may be particularly susceptible to bullying. Sport participation has been identified as a possible mechanism to prevent bullying behaviors, yet few researchers have explored bullying within the context of sport. The purpose of this qualitative description study was to explore young Aboriginal women's experiences of bullying in team sports. Eight young Aboriginal women participated in one-on-one semistructured interviews and follow-up phone interviews. Data were analyzed using a content analysis, and findings were represented by five themes: (1) mean mugging, (2) sport specific, (3) happens all the time, (4) team bonding to address bullying, and (5) prevention through active coaches. The detailed descriptions shared by participants provide insight into a broad range of bullying experiences and serve as a foundation for addressing the bullying that occurs in sport.

    2016-05-01

    Contemporary bioethics recognizes the importance of the culture in shaping ethical issues, yet in practice, a process for ethical analysis and decision making is rarely adjusted to the culture and ethnicity of involved parties. This is of a particular concern in a health care system that is caring for a growing Aboriginal population. We raise the possibility of constructing a bioethics grounded in traditional Aboriginal knowledge. As an example of an element of traditional knowledge that contains strong ethical guidance, we present the story of the Gifts of the Seven Grandfathers. We note a resemblance of this Ojibway teaching to virtue ethics in European traditions, but we suggest that there are also important differences in how these two traditions are currently presented. We hope that further engagement with a variety of indigenous moral teachings and traditions could improve health care involving Aboriginal patients and communities, and enrich the discipline of bioethics.

  13. The Aboriginal Australian cosmic landscape. Part 1: the ethnobotany of the skyworld

    Science.gov (United States)

    Clarke, Philip A.

    2014-11-01

    In Aboriginal Australia, the corpus of cosmological beliefs was united by the centrality of the Skyworld, which was considered to be the upper part of a total landscape that possessed topography linked with that of Earth and the Underworld. Early historical accounts of classical Australian hunter-gatherer beliefs described the heavens as inhabited by human and spiritual ancestors who interacted with the same species of plants and animals as they had below. This paper is the first of two that describes Indigenous perceptions of the Skyworld flora and draws out major ethnobotanical themes from the corpus of ethnoastronomical records garnered from a diverse range of Australian Aboriginal cultures. It investigates how Indigenous perceptions of the flora are interwoven with Aboriginal traditions concerning the heavens, and provides examples of how the study of ethnoastronomy can provide insights into the Indigenous use and perception of plants.

  14. Environmental agreements, EIA follow-up and aboriginal participation in environmental management: The Canadian experience

    International Nuclear Information System (INIS)

    During the last decade a number of environmental agreements (EAs) have been negotiated in Canada involving industry, government and Aboriginal peoples. This article draws on the Canadian experience to consider the potential of such negotiated agreements to address two issues widely recognised in academic and policy debates on environmental impact assessment (EIA) and environmental management. The first relates to the need to secure indigenous participation in environmental management of major projects that affect indigenous peoples. The second and broader issue involves the necessity for specific initiatives to ensure effective follow-up of EIA. The Canadian experience indicates that negotiated environmental agreements have considerable potential to address both issues. However, if this potential is to be realized, greater effort must be made to develop structures and processes specifically designed to encourage Aboriginal participation; and EAs must themselves provide the financial and other resource required to support EIA follow-up and Aboriginal participation

  15. Problems of communicating radiation doses to aboriginal members of the public in the Alligator Rivers Region

    International Nuclear Information System (INIS)

    Since the early 1970s, Aboriginal people of the Alligator Rivers Region have had to come to grips with the effects of uranium mining at Nabarlek and Ranger. One element in their cost-benefit approach to mine operations has been the expectation that bush foods in the region will not be contaminated by the mining operations. Recent studies on radionuclide concentrations in freshwater mussels (Velesunio angasi) in the region have shown this species, and perhaps others, to be efficient accumulators of radium. Information concerning natural radium accumulation in mussels and accompanying health risk estimates have been conveyed to Aboriginal people of the area and such information transfer has not been without its problems. Application of the ALARA principle to environmental management of the effluent pathways needs to consider Aboriginal expectations

    The authors present an analysis of transcultural psychiatry research in relation to three main population groups in Australia: Aboriginal Australians, documented immigrants, and refugees. The pioneering reports produced by Western psychiatrists in Aboriginal communities are examined in this article. Additional quantitative and qualitative studies developed with Aboriginal people in the context of a traumatic acculturation process are also reviewed. Subsequently, the authors examine the challenges faced by immigrants with mental disorders in a health care system still unequipped to treat a new array of clinical presentations unfamiliar to the clinical staff. The authors also highlight the development of policies aimed at providing quality mental health care to a mosaic of cultures in an evolving multicultural society. Lastly, the psychiatric manifestations of refugees and asylum seekers are analysed in the context of a series of vulnerabilities and deprivations they have experienced, including basic human rights.

    Interventions for family violence in Aboriginal communities should take a culture-based approach and focus on healing for the whole family. The purpose of this research was to identify risk issues from the perspective of service providers for couples counseling with Aboriginal clients following intimate partner violence. A total of 25 service providers participated in over the phone interviews concerning risk with Aboriginal men in couple counseling. Five concepts emerged including (a) collaterals, (b) commitment to change, (c) violence, (d) mind-set, and (e) mental health. It was concluded that culturally competent interventions should involve the entire community and have a restorative approach. The concepts were compared and contrasted with the available literature.

  18. Aboriginal Astronomical Traditions from Ooldea, South Australia, Part 1: Nyeeruna and the Orion Story

    CERN Document Server

    Leaman, Trevor M

    2014-01-01

    Whilst camped at Ooldea, South Australia, between 1919 and 1935, the amateur anthropologist Daisy Bates CBE (1859-1951) recorded the daily lives, lore, and oral traditions of the Aboriginal people of the Great Victoria Desert region surrounding Ooldea. Among her archived notes are stories regarding the Aboriginal astronomical traditions of this region. One story in particular, involving the stars making up the modern western constellations of Orion and Taurus, and thus referred to here as "The Orion Story", stands out for its level of detail and possible references to transient astronomical phenomena. Here, we critically analyse several important elements of "The Orion Story", including its relationship to an important secret-sacred male initiation rite. This paper is the first in a series attempting to reconstruct a more complete picture of the sky knowledge and star lore of the Aboriginal people of the Great Victoria Desert.

As part of the larger WHEALTH study, we gathered qualitative health data on midlife Aboriginal women living both on and off reserves. Despite careful planning and a commitment to methodological congruence and purposiveness we encountered a number of challenges that raised ethical questions. We present how we addressed these issues as we attempted to produce ethical, culturally sensitive, and sound research in a timely fashion. This article provides important considerations for other researchers and funding bodies while illustrating the benefits of working with Aboriginal women as an under researched population.

  20. The Aboriginal Australian cosmic landscape. Part 2: Plant connections with the skyworld

    2015-03-01

    In the recorded mythology of Aboriginal Australia there is frequent mention of the Skyworld as the upper part of a total landscape that possessed topography linked with that of Earth and the Underworld. The heavens were perceived as a country with the same species of plants and animals that existed below. In Aboriginal tradition, large trees were seen as connecting terrestrial space with the sky above, while the movements of celestial bodies were linked to seasonal changes observed with plants on Earth. This paper describes the links between the floras of Earth and the Skyworld.

    2010-01-01

    We present evidence that the Boorong Aboriginal people of northwestern Victoria observed the Great Eruption of Eta ({\\eta}) Carinae in the nineteenth century and incorporated the event into their oral traditions. We identify this star, as well as others not specifically identified by name, using descriptive material presented in the 1858 paper by William Edward Stanbridge in conjunction with early southern star catalogues. This identification of a transient astronomical event supports the assertion that Aboriginal oral traditions are dynamic and evolving, and not static. This is the only definitive indigenous record of {\\eta} Carinae's outburst identified in the literature to date.

    Full Text Available Abstract Background Measuring the real burden of cardiovascular disease in Australian Aboriginals is complicated by under-identification of Aboriginality in administrative health data collections. Accurate data is essential to measure Australia's progress in its efforts to intervene to improve health outcomes of Australian Aboriginals. We estimated the under-ascertainment of Aboriginal status in linked morbidity and mortality databases in patients hospitalised with cardiovascular disease. Methods Persons with public hospital admissions for cardiovascular disease in Western Australia during 2000-2005 (and their 20-year admission history or who subsequently died were identified from linkage data. The Aboriginal status flag in all records for a given individual was variously used to determine their ethnicity (index positive, and in all records both majority positive or ever positive and stratified by region, age and gender. The index admission was the baseline comparator. Results Index cases comprised 62,692 individuals who shared a total of 778,714 hospital admissions over 20 years, of which 19,809 subsequently died. There were 3,060 (4.9% persons identified as Aboriginal on index admission. An additional 83 (2.7% Aboriginal cases were identified through death records, increasing to 3.7% when cases with a positive Aboriginal identifier in the majority (≥50% of previous hospital admissions over twenty years were added and by 20.8% when those with a positive flag in any record over 20 years were incorporated. These results equated to underestimating Aboriginal status in unlinked index admission by 2.6%, 3.5% and 17.2%, respectively. Deaths classified as Aboriginal in official records would underestimate total Aboriginal deaths by 26.8% (95% Confidence Interval 24.1 to 29.6%. Conclusions Combining Aboriginal determinations in morbidity and official death records increases ascertainment of unlinked cardiovascular morbidity in Western Australian

    Full Text Available Abstract Background Collaborative, culturally safe services that integrate clinical approaches with traditional Aboriginal healing have been hailed as promising approaches to ameliorate the high rates of mental health problems in Aboriginal communities in Canada. Overcoming significant financial and human resources barriers, a mental health team in northern Ontario is beginning to realize this ideal. We studied the strategies, strengths and challenges related to collaborative Aboriginal mental health care. Methods A participatory action research approach was employed to evaluate the Knaw Chi Ge Win services and their place in the broader mental health system. Qualitative methods were used as the primary source of data collection and included document review, ethnographic interviews with 15 providers and 23 clients; and 3 focus groups with community workers and managers. Results The Knaw Chi Ge Win model is an innovative, community-based Aboriginal mental health care model that has led to various improvements in care in a challenging rural, high needs environment. Formal opportunities to share information, shared protocols and ongoing education support this model of collaborative care. Positive outcomes associated with this model include improved quality of care, cultural safety, and integration of traditional Aboriginal healing with clinical approaches. Ongoing challenges include chronic lack of resources, health information and the still cursory understanding of Aboriginal healing and outcomes. Conclusions This model can serve to inform collaborative care in other rural and Indigenous mental health systems. Further research into traditional Aboriginal approaches to mental health is needed to continue advances in collaborative practice in a clinical setting.

    Cultural self-efficacy refers to how capable one feels functioning in culturally diverse situations. The purpose of this study was to gain a better understanding of cultural self-efficacy among nursing students, specifically in relation to individuals of Aboriginal ancestry. The authors examined the extent to which intercultural anxiety, intercultural communication, and experience with persons of Aboriginal ancestry predicted two aspects of cultural self-efficacy, namely, knowledge and skills. In this correlational study, non-Aboriginal Canadian nursing students (N = 59) completed a survey assessing these variables. Overall, cultural self-efficacy was rated as moderate by nursing students. Regression analyses indicated that greater intercultural communication skills and experience with persons of Aboriginal ancestry were significant unique predictors of higher cultural knowledge self-efficacy. Greater intercultural communication and lower intercultural anxiety significantly predicted higher cultural skills self-efficacy. The results provide direction to nursing programs interested in facilitating higher levels of cultural self-efficacy among nursing students. PMID:22477719

    Maureen Dobbins

    2010-02-01

    Full Text Available Within Canadian Aboriginal communities, the process for utilizing environmental health research evidence in the development of policies and programs is not well understood. This fundamental qualitative descriptive study explored the perceptions of 28 environmental health researchers, senior external decision-makers and decision-makers working within Aboriginal communities about factors influencing knowledge transfer and exchange, beliefs about research evidence and Traditional Knowledge and the preferred communication channels for disseminating and receiving evidence. The results indicate that collaborative relationships between researchers and decision-makers, initiated early and maintained throughout a research project, promote both the efficient conduct of a study and increase the likelihood of knowledge transfer and exchange. Participants identified that empirical research findings and Traditional Knowledge are different and distinct types of evidence that should be equally valued and used where possible to provide a holistic understanding of environmental issues and support decisions in Aboriginal communities. To facilitate the dissemination of research findings within Aboriginal communities, participants described the elements required for successfully crafting key messages, locating and using credible messengers to deliver the messages, strategies for using cultural brokers and identifying the communication channels commonly used to disseminate and receive this type of information.

    2013-01-01

    The author comments her experience in the practice of medicine and public health among aborigines in Formosa, a long neglected province in northeast Argentina. Her experience goes through a span of 34 years, 11 in a small community in a far off region. The province has 530162 inhabitants, 43358 (6.5%) aborigines of the Wichí, Qom, and Pilagá ethnicities. Some particular public health problems of these aborigines are due to the great distance between communities and the regular medical assistance while others are related to cultural differences. The situation has gradually improved in the last 30 years due to government awareness in providing easy and close access to medical care, making the most of the abilities of local aborigines midwifes, teaching health assistants and conventional measures. The most apparent results are the decrease in infant mortality rates and the lower incidence of tuberculosis, with no deaths due to tuberculous meningitis since 1999. No less important was the opening of new opportunities for education and the teaching of both native and Spanish language in the schools retaining local customs. The changes have brought about new risks and challenges such as: traffic accidents involving youngsters riding motorcycles, alcoholism, obesity, diabetes (undiagnosed beforehand), high rate of adolescence pregnancy, and crisis of leadership within the communities.

    Catherine M. Demosthenous

    2012-06-01

    Full Text Available The inclusion of Indigenous people in universities is an important policy issue, as evidenced by the Review of Higher Education and Outcomes for Aboriginal and Torres Strait Islander people, which is currently underway. While the Review aims to collectively address access and outcomes for Aboriginal and Torres Strait Islander people in universities to ensure parity in the sector, a key contributor to those outcomes is that of participation. This article examines a focus group interaction in which Aboriginal and Torres Strait Islander students are yarning about their experiences of participating in university life, using Ethnomethodology (EM and its analytic methods. Premised on the understanding that language is action, the study examines the students’ use of personal pronouns and particularly the first person pronoun ‘we’, using the inclusive/exclusive distinction. Applying this pronominal system here provides insights into the notion of inclusion/exclusion for Aboriginal and Torres Strait Islander students in Australian higher education, and for understanding how ‘we’ matter(s in everyday university life.

  6. Thin shell model revisited

    CERN Document Server

    Gao, Sijie

    2014-01-01

    We reconsider some fundamental problems of the thin shell model. First, we point out that the "cut and paste" construction does not guarantee a well-defined manifold because there is no overlap of coordinates across the shell. When one requires that the spacetime metric across the thin shell is continuous, it also provides a way to specify the tangent space and the manifold. Other authors have shown that this specification leads to the conservation laws when shells collide. On the other hand, the well-known areal radius $r$ seems to be a perfect coordinate covering all regions of a spherically symmetric spacetime. However, we show by simple but rigorous arguments that $r$ fails to be a coordinate covering a neighborhood of the thin shell if the metric across the shell is continuous. When two spherical shells collide and merge into one, we show that it is possible that $r$ remains to be a good coordinate and the conservation laws hold. To make this happen, different spacetime regions divided by the shells must...

    2013-11-01

    Full Text Available Knowledge of the Aboriginal socio-political history in Canada has historically been excluded from public education. In Ontario, public school children learn about Aboriginal people at specific times in the curriculum. However, teachers frequently only teach the bare essentials about Aboriginal people in Canada because they do not have adequate knowledge or feel that they lack the ability to teach about this subject. The Ontario Institute of Studies in Education at the University of Toronto has implemented the Deepening Knowledge Project to provide teacher candidates with an increased awareness and knowledge about Aboriginal history, culture, and worldview for their future teaching careers. This article will provide insight into the project and the curriculum developed for working with teacher candidates.

    Aboriginal youth are at disproportionate risk for depression and substance use problems. Increasingly, developmental theories have shifted from focusing on vulnerabilities to protective factors for adolescent depression. In particular, theories emphasizing protective factors are relevant when understanding the mental health of Aboriginal youth. However, it is unclear which factors protect against depressive symptomatology among Aboriginal adolescents to promote optimal development. Using multilevel growth curve modeling, the present study had three main objectives. First, we aimed to model the developmental trajectory of depressive symptoms using a sample of off-reserve Aboriginal youth from a national Canadian dataset (ages 12-23). Second, we sought to examine the relationship between alcohol use behaviors, self-esteem, optimism, and the trajectories of depressive symptoms. Lastly, we investigated whether self-esteem and optimism mediated the relationship between alcohol use and depressive symptoms. Gender differences were also examined within each of the study objectives. A sample of off-reserve Aboriginal youth (N = 283; 48.3% male) was selected from cycles 4-7 of the National Longitudinal Survey of Children and Youth. Heavy drinking was a risk factor for depressive symptoms, while self-esteem and optimism were key protective factors for depressive symptoms among early adolescent Aboriginal youth. Further, the developmental trajectory of depressive symptoms among Canadian Aboriginal youth differed for boys and girls once accounting for risk and protective factors. Thus, it is valuable to integrate the protective role of self-esteem and optimism into developmental theories of depression and mental health intervention programs for early adolescent Aboriginal youth.

    formadores. Basados en la experiencia Norteamericana entregamos además, un resumen de los métodos existentes para la detección y análisis de dichos depósitos, los sesgos asociados, así como el aporte potencial que su análisis podría representar en futuros estudios paleoecológicos en las zonas áridas y semiáridas de SudaméricaIn arid and semi-arid regions of South America, historical evidence for climate and vegetation change is scarce despite its importance for determining reference conditions and rates of natural variability in areas susceptible to modern desertification. Normal lines of evidence, such as pollen stratigraphies from lakes, are either rare or unobtainable in deserts; studies of late Quaternary vegetation history are few and generally inconclusive. This gap in knowledge may be corrected with discovery and development of fossil rodent middens in rocky environments throughout arid South America. These middens, mostly the work of Lagidium, Phyllotis, Abrocoma and Octodontomys, are rich in readily identifiable plant macrofossils, cuticles and pollen, as well as vertebrate and insect remains. In the North American deserts, more than 2,500 woodrat (Neotoma middens analyzed since 1960 have yielded a detailed history of environmental change during the past 40,000 years. Preliminary work in the pre-puna, Monte and Patagonian Deserts of western Argentina, the Atacama Desert of northern Chile/southern Peru, the Mediterranean matorral of central Chile, and the Puna of the Andean altiplano suggest a similar potential for rodent middens in South America. Here we borrow from the North American experience to synthesize methodologies and approaches, summarize preliminary work, and explore the potential of rodent midden research in South America

Child development level was compared between the two groups. Methods: Teachers completed screening questionnaires for ADHD, ASD, and development level for 36- to 72-month-old children in kindergartens in Taiwan. The questionnaire results were compared between the aboriginal and nonaboriginal children. One child psychiatrist then interviewed the aboriginal preschool children to determine if they had ADHD and/or ASD. Results: We collected 93 questionnaires from the aboriginal group and 60 from the nonaboriginal group. In the aboriginal group, 5.37% of the children were identified to have ADHD, while 1.08% were identified to have ASD. Significantly fewer aboriginal children had developmental delays for situation comprehension and personal–social development (P=0.012 and 0.002, respectively than nonaboriginal children. Conclusion: Aboriginal children in Taiwan had typical percentages of ADHD and ASD compared to those published in the literature. Aboriginal children showed relative strengths in situation

    On microscopic scales, the crystallinity of flexible tethered or cross-linked membranes determines their mechanical response. We show that by controlling the type, number, and distribution of defects on a spherical elastic shell, it is possible to direct the morphology of these structures. Our numerical simulations show that by deflating a crystalline shell with defects, we can create elastic shell analogs of the classical platonic solids. These morphologies arise via a sharp buckling transition from the sphere which is strongly hysteretic in loading or unloading. We construct a minimal Landau theory for the transition using quadratic and cubic invariants of the spherical harmonic modes. Our approach suggests methods to engineer shape into soft spherical shells using a frozen defect topology.

    2010-09-01

    It is generally recognised that poor living conditions and poor hygiene underlie the high burden of infection experienced by Indigenous (Aboriginal and Torres Strait Islander) children living in remote communities. There has been little research on this topic. Taking an ecological approach, our study aimed to identify the key factors contributing to poor hygiene in one remote Aboriginal community and to determine appropriate approaches for improving hygiene and reducing the burden of infection among children. Key findings include that multifaceted interventions are required to ensure that household water and sanitation technology are functional, hygiene behaviour change is achieved and environments that enable good hygiene behaviour are created. Many of the factors contributing to the problem of poor living conditions and poor hygiene in these communities are outside the control of the health system. Intersectoral collaboration and action is required to identify acceptable, effective and sustainable solutions. PMID:20854319

  18. From (b)edouin to (a)borigine: the myth of the desert noble savage.

    This article examines the myth of the supposed superiority of the desert noble savage over civilized man. With the Bedouin of Arabia and the Aborigines of Australia as its two prime examples, the article argues that two versions of this myth can be traced: one in which the desert noble savage is valorized due to his valour, physical prowess and martial skill (Bedouin); and another, later version, where the desert noble savage is valorized as a pacifist, an ecologist and a mythmaker/storyteller (Aborigines). The article concludes by examining the way in which this turn from one type of desert noble savage to another reflects the manner in which western modernity has shifted its values from Cartesian dualities and Enlightenment rationalism to that of networks, potentialities, ecology and myth.

    This research was designed to investigate the conceptualisations and thinking strategies Indigenous Australian students use in counting tasks. Eighteen Aboriginal students, in years 1 to 11 at a remote community school, were interviewed using standard counting tasks and a `counting' task that involved fetching `maku' (witchetty grubs) to have enough to give a maku to each person in a picture. The tasks were developed with, and the interviews conducted by, an Aboriginal research assistant, to ensure appropriate cultural and language contexts. A main finding was that most of the students did not see the need to use counting to make equivalent sets, even though they were able to demonstrate standard counting skills. The findings highlight a need to further examine the world views, orientations and related mathematical concepts and processes that Indigenous students bring to school.

    Australian Indigenous astronomical traditions hint at a relationship between animals in the skyworld and the behaviour patterns of their terrestrial counterparts. In our continued study of Aboriginal astronomical traditions from the Great Victoria Desert, South Australia, we investigate the relationship between animal behaviour and stellar positions. We develop a methodology to test the hypothesis that the behaviour of these animals is predicted by the positions of their celestial counterparts at particular times of the day. Of the twelve animals identified in the Ooldean sky, the nine stellar (i.e. non-planet or non-galactic) associations were analysed and each demonstrated a close connection between animal behaviour and stellar positions. We suggest that this may be a recurring theme in Aboriginal astronomical traditions, requiring further development of the methodology.

    This study investigated the dental health status, dietary habits, oral hygiene levels, and caretaker risk indicators among Taiwanese children. This cross-sectional purposive sampling study included 256 aboriginal children, 6 to 9 years old, living in remote regions in southern Taiwan. Participants received dental examinations, and questionnaires were completed by caretakers. Data were analyzed using the χ(2) test, t test, and multiple logistic regressions. The deft (sum of decayed, extracted, and filled primary teeth) and defs (sum of the decayed, extracted, and filled primary dentition surfaces) indices were affected by the frequencies of drinking sweetened beverages (P = .0006) and daily toothbrushing (P = .0032). Caretakers' toothbrushing frequency was a significant predictor of children's oral hygiene status (P oral hygiene was 2.04 (P = .0184). Oral hygiene among aboriginal children in this study was inadequate. Caretakers' toothbrushing frequency and betel quid habit were significant predictors of poor children's oral hygiene.

    Primary biliary cirrhosis (PBC) is a well-known but uncommon chronic liver disease that is presumed to be of autoimmune etiology. Recently, investigations in British Columbia (BC), a province of Canada situated along the Pacific North-West of North America, have suggested that PBC is not a rare disease amongst BC's Aboriginal (i.e. First Nations) communities. Geographically, BC is adjacent to South East Alaska, an American state that has also reported an increased prevalence of PBC amongst its Aboriginal communities. In this article, the medical evidence supporting a hypothesis of increased risk of PBC amongst BC's First Nations communities is reviewed. Evidence suggesting that autoimmune hepatitis is also more likely amongst BC's First Nations communities is also presented.(C)2006 The WJG Press. All rights reserved.

  4. Dynamic Analysis of Shells

    Full Text Available Shell structures are indispensable in virtually every industry. However, in the design, analysis, fabrication, and maintenance of such structures, there are many pitfalls leading to various forms of disaster. The experience gained by engineers over some 200 years of disasters and brushes with disaster is expressed in the extensive archival literature, national codes, and procedural documentation found in larger companies. However, the advantage of the richness in the behavior of shells is that the way is always open for innovation. In this survey, we present a broad overview of the dynamic response of shell structures. The intention is to provide an understanding of the basic themes behind the detailed codes and stimulate, not restrict, positive innovation. Such understanding is also crucial for the correct computation of shell structures by any computer code. The physics dictates that the thin shell structure offers a challenge for analysis and computation. Shell response can be generally categorized by states of extension, inextensional bending, edge bending, and edge transverse shear. Simple estimates for the magnitudes of stress, deformation, and resonance in the extensional and inextensional states are provided by ring response. Several shell examples demonstrate the different states and combinations. For excitation frequency above the extensional resonance, such as in impact and acoustic excitation, a fine mesh is needed over the entire shell surface. For this range, modal and implicit methods are of limited value. The example of a sphere impacting a rigid surface shows that plastic unloading occurs continuously. Thus, there are no short cuts; the complete material behavior must be included.

    Full Text Available Psychosocial processes are implicated as mediators of racial/ethnic health disparities via dysregulation of physiological responses to stress. Our aim was to investigate the extent to which factors previously documented as buffering the impact of high-risk family environments on Aboriginal youths' psychosocial functioning were similarly beneficial for their physical health status.We examined the relationship between psychosocial resilience and physical health of urban Aboriginal youth (12-17 years, n = 677 drawn from a representative survey of Western Australian Aboriginal children and their families. A composite variable of psychosocial resilient status, derived by cross-classifying youth by high/low family risk exposure and normal/abnormal psychosocial functioning, resulted in four groups- Resilient, Less Resilient, Expected Good and Vulnerable. Separate logistic regression modeling for high and low risk exposed youth revealed that Resilient youth were significantly more likely to have lower self-reported asthma symptoms (OR 3.48, p<.001 and carer reported lifetime health problems (OR 1.76, p<.04 than Less Resilient youth.The findings are consistent with biopsychosocial models and provide a more nuanced understanding of the patterns of risks, resources and adaptation that impact on the physical health of Aboriginal youth. The results support the posited biological pathways between chronic stress and physical health, and identify the protective role of social connections impacting not only psychosocial function but also physical health. Using a resilience framework may identify potent protective factors otherwise undetected in aggregated analyses, offering important insights to augment general public health prevention strategies.

    In view of the geographically closest location to Andaman archipelago,Myanmar was suggested to be the origin place of aboriginal Andamanese.However,for lacking any genetic information from this region,which has prevented to resolve the dispute on whether the aboriginal Andamanese were originated from mainland India or Myanmar.To solve this question and better understand the origin of the aboriginal Andamanese,we screened for haplogroups M31(from which Andaman-specific lineage M31a1 branched off)and M32 among 846mitochondrial DNAs(mtDNAs)sampled across Myanmar.As a result,two Myanmar individuals belonging to haplogroup M31 were identified,and completely sequencing the entire mtDNA genomes of both samples testified that the two M31 individuals observed in Myanmar were probably attributed to the recent gene flow from northeast India populations.Since no root lineages of haplogroup M31 or M32 were observed in Myanmar,it is unlikely that Myanmar may serve as the source place of the aboriginal Andamanese.To get further insight into the origin of this unique population,the detailed phylogenetic and phylogeographic analyses were performed by including additional 7 new entire mtDNA genomes and 113 M31 mtDNAs pinpointed from South Asian populations,and the results suggested that Andaman-specific M31a1 could in fact trace its origin to northeast India.Time estimation results further indicated that the Andaman archipelago was likely settled by modern humans from northeast India via the land-bridge which connected the Andaman archipelago and Myanmar around the Last Glacial Maximum(LGM),a scenario in well agreement with the evidence from linguistic and palaeoclimate studies.

  15. Food, food choice and nutrition promotion in a remote Australian Aboriginal community.

    Colles, Susan L; Maypilama, Elaine; Brimblecombe, Julie

    2014-01-01

    Contemporary diets of Aboriginal people living in remote Australia are characterised by processed foods high in fat and sugar. Within the 'new' food system, evidence suggests many Aboriginal people understand food in their own terms but lack access to consumer information about store-purchased foods, and parents feel inadequate as role models. In a remote Australian Aboriginal community, purposive sampling identified adults who participated in semistructured interviews guided by food-based themes relating to the contemporary food system, parental guidance of children's food choice and channels through which people learn. Interpretive content analysis was used to identify salient themes. In discussions, people identified more closely with dietary qualities or patterns than nutrients, and valued a balanced, fresh diet that made them feel 'light'. People possessed basic knowledge of 'good' store foods, and wanted to increase familiarity and experience with foods in packets and cans through practical and social skills, especially cooking. Education about contemporary foods was obtained from key family role models and outside the home through community-based organisations, including school, rather than pamphlets and flip charts. Freedom of choice was a deeply held value; carers who challenged children's autonomy used strategic distraction, or sought healthier alternatives that did not wholly deny the child. Culturally safe approaches to information sharing and capacity building that contribute to the health and wellbeing of communities requires collaboration and shared responsibility between policy makers, primary healthcare agencies, wider community-based organisations and families.

    Full Text Available Abstract Background Betel quid, chewed by about 600 million people worldwide, is one of the most widely used addictive substances. Cessation factors in betel quid chewers are unknown. The present study explores prevalence and the quit rate of betel quid chewing in Taiwan aborigines. Our goal was to delineate potential predictors of chewing cessation. Methods A stratified random community-based survey was designed for the entire aborigines communities in Taiwan. A total of 7144 participants were included between June 2003 and May 2004 in this study. Information on sociodemographic characteristics, such as gender, age, obesity, education years, marital status, ethnicity, and habits of betel quid chewing, smoking and drinking was collected by trained interviewers. Results The prevalence of betel quid chewers was 46.1%. Betel quid chewing was closely associated with obesity (OR = 1.61; 95% CI: 1.40–1.85. Betel quid chewers were most likely to use alcohol and cigarettes together. Quit rate of betel quid chewers was 7.6%. Betel quid chewers who did not drink alcohol were more likely to quit (OR = 1.89; 95% CI: 1.43–2.50. Alcohol use is a significant factor related to cessation of betel quid chewing, but smoking is not. Conclusion Taiwan aborigines have a high prevalence of betel quid chewers and a low quit rate. Alcohol use is strongly association with betel quid chewing. Efforts to reduce habitual alcohol consumption might be of benefit in cessation of betel quid chewing.

  17. Aboriginal fisher perspectives on use of biotelemetry technology to study adult Pacific salmon

    2012-12-01

    Full Text Available Biotelemetry has become a popular tool accepted by the scientific community as a reliable approach for studying wild fish. However, stakeholder perspectives on scientific techniques and the information they generate are not uniformly positive. Aboriginal groups in particular may have opposition or apprehension to telemetry as a research tool. To that end, we conducted a river-bank survey of 111 aboriginal First Nations fishers that target adult Pacific salmon in the lower Fraser River, British Columbia, Canada. The majority of respondents had heard of telemetry, but few had knowledge of its function. Most responses regarding the use of telemetry in fisheries science were positive. The few negative perspectives were primarily concerned about the effects of tagging procedures whereas positive perspectives arose because telemetry was perceived to generate information on migration patterns and survival. Over half of the respondents would trust data arising from telemetry studies, but some had conditions related to the group conducting the research and their experience with fish handling. Several respondents noted the need for additional consultation and outreach with aboriginal communities (especially fishers to better inform them of study questions and techniques which, in the case of telemetry studies, could promote better participation in tag return programs and uptake of knowledge emanating from use of telemetry.

  18. Colour-Blind: Discursive Repertoires Teachers Used to Story Racism and Aboriginality in Urban Prairie Schools

    Directory of Open Access Journals (Sweden)

    Tyler McCreary

    2011-12-01

    Full Text Available This qualitative study explores how teachers' constructions of racism consistently minimized its pervasiveness in the school. Teachers constructed racism as individual not systemic, construed it as a phenomenon of places outside the school, and attributed responsibility for addressing racism to other people, particularly Aboriginal populations. Based on written responses from 95 Canadian Prairie teachers from two schools, this research examines the discourses teachers employed to narrate racism, particularly with relation to Aboriginal students. While there were some differences between inner city and suburban teachers, teachers from both environments followed discursive repertoires that absolved themselves of responsibility for addressing racism and maintained the colour-blind image of education. Interrogating these discursive repertoires exposes the systems of denial that block meaningful action upon racialized inequalities and prevent the development of a truly inclusive educational environment. This underlines the need for expanded anti-racist professional development to support critical racial reflexivity among in-service teachers.Keywords: racism in education; critical whiteness studies; in-service teachers; Aboriginal education

    Full Text Available Through references to four anecdotes, this article approaches the complex and often neglected topic of the relationship between Sicilian migrants in Australia and Aborigines. It does so not in search of clear evidences that may structure a well-defined historical narrative, but rather looking for moments of truth that may open up new dialogues, narratives, research. Within embodied otherness, it is the uncanny feeling towards the racialised other that most effectively make us understand the complex relationship Italian migrants have had with the (unfamiliar. The concept of the uncanny helps us understand that the racism of many Italian migrants towards Aboriginal people in Australia has not been resulting from a frightening encounter with the other, with the unfamiliar, with the difference. It has rather been the result of the return of what has been repressed from historical memory, namely the colonial character of Italian unification, Italians’ own racist and colonial history, the colonial nature of many Italian migrants’ settlement abroad, and the identification of southern Italians as the colonised, racialised others, in Italy and abroad. Through positive examples of emotional, intimate and political engagement between Sicilians and Aborigines, this article also consider people’s agency in moving within and challenging the constraining, intricate pervasiveness of the racial and colonial dictate in contemporary Australian society.

  20. Hepatitis C Virus in American Indian/Alaskan Native and Aboriginal Peoples of North America

    2012-12-01

    Full Text Available Liver diseases, such as hepatitis C virus (HCV, are “broken spirit” diseases. The prevalence of HCV infection for American Indian/Alaskan Native (AI/AN in the United States and Canadian Aboriginals varies; nonetheless, incidence rates of newly diagnosed HCV infection are typically higher relative to non-indigenous people. For AI/AN and Aboriginal peoples risk factors for the diagnosis of HCV can reflect that of the general population: predominately male, a history of injection drug use, in midlife years, with a connection with urban centers. However, the face of the indigenous HCV infected individual is becoming increasingly female and younger compared to non-indigenous counterparts. Epidemiology studies indicate that more effective clearance of acute HCV infection can occur for select Aboriginal populations, a phenomenon which may be linked to unique immune characteristics. For individuals progressing to chronic HCV infection treatment outcomes are comparable to other racial cohorts. Disease progression, however, is propelled by elevated rates of co-morbidities including type 2 diabetes and alcohol use, along with human immunodeficiency virus (HIV co-infection relative to non-indigenous patients. Historical and personal trauma has a major role in the participation of high risk behaviors and associated diseases. Although emerging treatments provide hope, combating HCV related morbidity and mortality will require interventions that address the etiology of broken spirit diseases.

    2010-07-01

    Full Text Available Abstract Background Solvent abuse is a particularly serious issue affecting Aboriginal people. Here we examine the association between solvent use and socio-demographic variables, drug-related risk factors, and pathogen prevalence in Aboriginal injection drug users (IDU in Manitoba, Canada. Methods Data originated from a cross-sectional survey of IDU from December 2003 to September 2004. Associations between solvent use and variables of interest were assessed by multiple logistic regression. Results A total of 266 Aboriginal IDU were included in the analysis of which 44 self-reported recent solvent use. Hepatitis C infection was 81% in solvent-users, compared to 55% in those reporting no solvent use. In multivariable models, solvent-users were younger and more likely to be infected with hepatitis C (AOR: 3.5; 95%CI: 1.3,14.7, to have shared needles in the last six months (AOR: 2.6; 95%CI:1.0,6.8, and to have injected talwin & Ritalin (AOR: 10.0; 95%CI: 3.8,26.3. Interpretation High hepatitis C prevalence, even after controlling for risky injection practices, suggests that solvent users may form closed networks of higher risk even amongst an already high-risk IDU population. Understanding the social-epidemiological context of initiation and maintenance of solvent use is necessary to address the inherent inequalities encountered by this subpopulation of substance users, and may inform prevention strategies for other marginalized populations.

    2016-07-01

    Full Text Available Objective: Translation of evidence into practice by health systems can be slow and incomplete and may disproportionately impact disadvantaged populations. Coronary heart disease is the leading cause of death among Aboriginal Australians. Timely access to effective medical care for acute coronary syndrome substantially improves survival. A quality-of-care audit conducted at a regional Western Australian hospital in 2011–2012 compared the Emergency Department management of Aboriginal and non-Aboriginal acute coronary syndrome patients. This audit is used as a case study of translating knowledge processes in order to identify the factors that support equity-oriented knowledge translation. Methods: In-depth interviews were conducted with a purposive sample of the audit team and further key stakeholders with interest/experience in knowledge translation in the context of Aboriginal health. Interviews were analysed for alignment of the knowledge translation process with the thematic steps outlined in Tugwell’s cascade for equity-oriented knowledge translation framework. Results: In preparing the audit, groundwork helped shape management support to ensure receptivity to targeting Aboriginal cardiovascular outcomes. Reporting of audit findings and resulting advocacy were undertaken by the audit team with awareness of the institutional hierarchy, appropriate timing, personal relationships and recognising the importance of tailoring messages to specific audiences. These strategies were also acknowledged as important in the key stakeholder interviews. A follow-up audit documented a general improvement in treatment guideline adherence and a reduction in treatment inequalities for Aboriginal presentations. Conclusion: As well as identifying outcomes such as practice changes, a useful evaluation increases understanding of why and how an intervention worked. Case studies such as this enrich our understanding of the complex human factors, including

    Full Text Available Abstract Background Mental Health First Aid (MHFA training was developed in Australia to teach members of the public how to give initial help to someone developing a mental health problem or in a mental health crisis situation. However, this type of training requires adaptation for specific cultural groups in the community. This paper describes the adaptation of the program to create an Australian Aboriginal and Torres Strait Islander Mental Health First Aid (AMHFA course and presents an initial evaluation of its uptake and acceptability. Methods To evaluate the program, two types of data were collected: (1 quantitative data on uptake of the course (number of Instructors trained and courses subsequently run by these Instructors; (2 qualitative data on strengths, weaknesses and recommendations for the future derived from interviews with program staff and focus groups with Instructors and community participants. Results 199 Aboriginal people were trained as Instructors in a five day Instructor Training Course. With sufficient time following training, the majority of these Instructors subsequently ran 14-hour AMHFA courses for Aboriginal people in their community. Instructors were more likely to run courses if they had prior teaching experience and if there was post-course contact with one of the Trainers of Instructors. Analysis of qualitative data indicated that the Instructor Training Course and the AMHFA course are culturally appropriate, empowering for Aboriginal people, and provided information that was seen as highly relevant and important in assisting Aboriginal people with a mental illness. There were a number of recommendations for improvements. Conclusion The AMHFA program is culturally appropriate and acceptable to Aboriginal people. Further work is needed to refine the course and to evaluate its impact on help provided to Aboriginal people with mental health problems.

    Full Text Available Child Sexual Assault (CSA in Aboriginal and Torres Strait Islander communities is a complex issue that cannot be understood in isolation from the ongoing impacts of colonial invasion, genocide, assimilation, institutionalised racism and severe socio-economic deprivation. Service responses to CSA are often experienced as racist, culturally, financially and/or geographically inaccessible. A two-day forum, National Yarn Up: Sharing the Wisdoms and Challenges of Young People and Sexual Abuse, was convened by sexual assault services to identify the main practice and policy concerns regarding working with Aboriginal and Torres Strait Islander children and young people (C&YP, families and communities in the context of CSA. The forum also aimed to explore how services can become more accountable and better engaged with the communities they are designed to support. The forum was attended by eighty invited Aboriginal and Torres Strait Islander and non-Aboriginal youth sexual assault managers and workers representing both “victim” and “those who sexually harm others” services. In keeping with Aboriginal Community-Based Research methods forum participants largely directed discussions and contributed to the analysis of key themes and recommendations reported in this article. The need for sexual assault services to prioritise cultural safety by meaningfully integrating Aboriginal and Torres Strait Islander Worldviews emerged as a key recommendation. It was also identified that collaboration between “victims” and “those who sexually harm” services are essential given Aboriginal and Torres Strait Islander C&YP who sexually harm others may have also been victims of sexual assault or physical violence and intergenerational trauma. By working with the whole family and community, a collaborative approach is more likely than the current service model to develop cultural safety and thus increase the accessibility of sexual assault services.

    We report on hollow shell-shell nanogels with two polymer shells that have different volume phase transition temperatures. By means of small angle neutron scattering (SANS) employing contrast variation and molecular dynamics (MD) simulations we show that hollow shell-shell nanocontainers are ideal systems for controlled drug delivery: The temperature responsive swelling of the inner shell controls the uptake and release, while the thermoresponsive swelling of the outer shell controls the size of the void and the colloidal stability. At temperatures between 32 °C shell. Computer simulations showed, that temperature induced switching of the permeability of the inner shell allows for the encapsulation in and release of molecules from the cavity.

  9. Dizzying Dialogue: Canadian Courts and the Continuing Justification of the Dispossession Of Aboriginal People

    Full Text Available Since Aboriginal rights have found protection within Canada’s Constitution, a new relationship has emerged between Canada’s Aboriginal Peoples and the Crown. This relationship is characterized by the need for “reconciliation.” In its growing jurisprudence, the Supreme Court of Canada applies reconciliation doctrine to several important Aboriginal claims. Each application, however, brings with it a restriction on Aboriginal rights. This paper argues that the Court’s conception of reconciliation is designed to facilitate the integration of Aboriginal peoples into larger society rather than to protect their collective interests. To demonstrate this argument, this paper examines the Supreme Court’s discussion of the doctrine of reconciliation from Sparrow (1990 to Little Salmon (2010. Depuis que les droits des autochtones sont protégés par la constitution canadienne, une nouvelle relation, ayant comme caractéristique le besoin de « réconciliation », a vu le jour entre les peuples autochtones du Canada et la Couronne. La Cour suprême du Canada a appliqué la doctrine de la réconciliation dans la série d’arrêts où elle s’est penchée sur plusieurs importantes revendications autochtones. Dans chaque cas, l’application de la doctrine de la réconciliation a cependant abouti à une restriction des droits des autochtones. Dans cet article, l’auteur soutient que, dans l’esprit de la Cour, la réconciliation vise à faciliter l’intégration des peuples autochtones dans la société en général plutôt qu’à protéger leurs intérêts collectifs. Pour étayer cette opinion, il examine l’analyse qu’a faite la Cour suprême de la doctrine de réconciliation de l’arrêt Sparrow (1990 à l’arrêt Little Salmon (2010.

    2016-09-01

    Aboriginal Canadians have low intakes of vitamin D and are shifting away from consumption of traditional foods. Higher body mass index, skin pigmentation, and geographic latitude of residence further predispose Canadian Aboriginal populations to low vitamin D status. Low vitamin D status could compromise bone health and other health outcomes. Studies assessing vitamin D status of different Aboriginal groups are limited. The aim of this review is to examine the literature on vitamin D status and intakes of Canadian Aboriginal populations living in the Arctic. PubMed was searched for relevant articles published from 1983 to 2013. The prevalence of 25-hydroxy vitamin D deficiency ranged from 13.9% to 76.0% among children and adults in the summer. Furthermore, mean vitamin D intakes among all age groups were below the estimated average requirement. As vitamin D deficiency has been recently associated with chronic diseases, and Aboriginal populations living in the Arctic are at high risk for low vitamin D status, their vitamin D status should be assessed regularly across seasons.

  11. Sweating it Out: Facilitating Corrections and Parole in Canada Through Aboriginal Spiritual Healing

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Aboriginal peoples continue to be subjected to drastic over-incarceration. Much of the existing literature explores contemporary adaptations of Aboriginal justice traditions that resemble restorative justice as a solution. There is by comparison a lack of literature that considers searching for solutions during the correctional phase of the justice system, after Aboriginal persons have already been convicted and imprisoned. The objective of this paper is to explore a number of reforms in order to better facilitate rehabilitation, reintegration, and parole for Aboriginal inmates. One is to invest greater resources into culturally sensitive programming that emphasizes spiritual healing for Aboriginal inmates. This is premised on the theme of “spend now, save later” with the idea that increasing the chances for Aboriginal re-integration may represent the better long term investment than simply warehousing large numbers of Aboriginal inmates year after year. Another problem is that many Aboriginal inmates are classified as higher security risks, which results in them being cut off from needed programming. The suggestion here is that criminal history as a static factor for determining security classifications may have little predictive value for the actual security risk posed by Aboriginal inmates, and therefore should be de-emphasized. Correctional Services of Canada should seriously consider developing an Aboriginal-specific classification scale that de-emphasizes criminal history, and emphasizes instead offender participation in culturally appropriate programs and spiritual healing, and behavioural progress while in prison. Risk assessment to re-offend for purposes of granting parole may also represent a form of systemic discrimination since criminal history represents a static factor that encumbers parole for many Aboriginal inmates. Risk assessment should instead emphasize dynamic risk factors by assessing Aboriginal participation in

    A novel method for fabricating diamond shells is introduced. The fabrication of such shells is a multi-step process, which involves diamond chemical vapor deposition on predetermined mandrels followed by polishing, microfabrication of holes, and removal of the mandrel by an etch process. The resultant shells of the present invention can be configured with a surface roughness at the nanometer level (e.g., on the order of down to about 10 nm RMS) on a mm length scale, and exhibit excellent hardness/strength, and good transparency in the both the infra-red and visible. Specifically, a novel process is disclosed herein, which allows coating of spherical substrates with optical-quality diamond films or nanocrystalline diamond films.

    Shell biorefinery, referring to the fractionation of crustacean shells into their major components and the transformation of each component into value-added chemicals and materials, has attracted growing attention in recent years. Since the large quantities of waste shells remain underexploited, their valorization can potentially bring both ecological and economic benefits. This Review provides an overview of the current status of shell biorefinery. It first describes the structural features of crustacean shells, including their composition and their interactions. Then, various fractionation methods for the shells are introduced. The last section is dedicated to the valorization of chitin and its derivatives for chemicals, porous carbon materials and functional polymers. PMID:27484462

    2014-06-01

    Body pride may be a predictor of health and well-being among Aboriginal youth. Body pride could potentially be addressed in health interventions, but it is critical to understand how body pride is conceptualized among Aboriginal youth. The purpose of this qualitative description study was to better understand the experiences of body pride among young Aboriginal women living in urban centers in Alberta, Canada. Eight young Aboriginal women (15-18 years old) participated in one-on-one interviews. A qualitative content analysis highlighted five themes that represent the participants' meanings of body pride. Participants described how body pride is: (a) accepting everything about your body, (b) who you are and how you show it, (c) connected to culture, (d) being healthy, and (e) being thankful to be Native. This research makes a contribution to the growing body pride literature by providing an initial glimpse into the complexities of young Aboriginal women's body pride experiences.

    Full Text Available Abstract Background Partnerships between different health services are integral to addressing the complex health needs of vulnerable populations. In Australia, partnerships between Aboriginal1 community controlled and mainstream services can extend health care options and improve the cultural safety of services. However, although government funding supports such collaborations, many factors can cause these arrangements to be tenuous, impacting the quality of health care received. Research was undertaken to explore the challenges and enhancers of a government initiated service partnership between an Aboriginal Community Controlled alcohol and drug service and three mainstream alcohol rehabilitation and support services. Methods Sixteen staff including senior managers (n=5, clinical team leaders (n=5 and counsellors (n=6 from the four services were purposively recruited and interviewed. Interviews were semi-structured and explored staff experience of the partnership including the client intake and referral process, shared client care, inter-service communication and ways of working. Results & discussion Communication issues, partner unfamiliarity, ‘mainstreaming’ of Aboriginal funding, divergent views regarding staff competencies, client referral issues, staff turnover and different ways of working emerged as issues, emphasizing the challenges of working with a population with complex issues in a persistent climate of limited resourcing. Factors enhancing the partnership included adding a richness and diversity to treatment possibilities and opportunities to explore different, more culturally appropriate ways of working. Conclusion While the literature strongly advises partnerships be suitably mature before commencing service delivery, the reality of funding cycles may require partnerships become operational before relationships are adequately consolidated. Allowing sufficient time and funding for both the operation and relational aspects of a

    OBJECTIVE To determine whether disparities in the nature and management of type 2 diabetes persist between Aboriginal and the majority Anglo-Celt patients in an urban Australian community. RESEARCH DESIGN AND METHODS Baseline data from the observational Fremantle Diabetes Study collected from 1993 to 1996 (phase I) and from 2008 to 2011 (phase II) were analyzed. Patients characterized as Aboriginal or Anglo-Celt by self-report and supporting data underwent comprehensive assessment, including questionnaires, examination, and biochemical testing in a single laboratory. Generalized linear modeling with age/sex adjustment was used to examine differences in changes in variables in the two groups between phases I and II. RESULTS The indigenous participants were younger at entry and at diabetes diagnosis than the Anglo-Celt participants in both phases. They were also less likely to be educated beyond primary level and were more likely to be smokers. HbA1c decreased in both groups over time (Aboriginal median 9.6% [interquartile range 7.8–10.7%] to 8.4% [6.6–10.6%] vs. Anglo-Celt median 7.1% [6.2–8.4%] to 6.7% [6.2–7.5%]), but the gap persisted (P = 0.65 for difference between phases I and II by ethnic group). Aboriginal patients were more likely to have microvascular disease in both phases. The prevalence of peripheral arterial disease (ankle-brachial index ≤0.90 or lower-extremity amputation) increased in Aboriginal but decreased in Anglo-Celt participants (15.8–29.7 vs. 30.7–21.5%; P = 0.055). CONCLUSIONS Diabetes management has improved for Aboriginal and Anglo-Celt Australian patients, but disparities in cardiovascular risk factors and complications persist. PMID:22815295

  17. Measuring emotional and social wellbeing in Aboriginal and Torres Strait Islander populations: an analysis of a Negative Life Events Scale

    Directory of Open Access Journals (Sweden)

    2007-11-01

    Full Text Available Abstract Aboriginal and Torres Strait Islander Australians experience widespread socioeconomic disadvantage and health inequality. In an attempt to make Indigenous health research more culturally-appropriate, Aboriginal and Torres Strait Islander Australians have called for more attention to the concept of emotional and social wellbeing (ESWB. Although it has been widely recognised that ESWB is of crucial importance to the health of Aboriginal and Torres Strait Islander peoples, there is little consensus on how to measure in Indigenous populations, hampering efforts to better understand and improve the psychosocial determinants of health. This paper explores the policy and political context to this situation, and suggests ways to move forward. The second part of the paper explores how scales can be evaluated in a health research setting, including assessments of endorsement, discrimination, internal and external reliability. We then evaluate the use of a measure of stressful life events, the Negative Life Events Scale (NLES, in two samples of Aboriginal people living in remote communities in the Northern Territory of Australia. We argue that the Negative Life Events Scale is a promising assessment of psychosocial wellbeing in Aboriginal and Torres Strait Islander populations. Evaluation of the scale and its performance in other samples of Aboriginal and Torres Strait Islander populations is imperative if we hope to develop better, rather than more, scales for measuring ESWB among Indigenous Australians. Only then will it be possible to establish standardized methods of measuring ESWB and develop a body of comparable literature that can guide both a better understanding of ESWB, and evaluation of interventions designed to improve the psychosocial health of Indigenous populations and decrease health inequalities.

    This report outlines the major positive impacts of vaccines on the health of Aboriginal and Torres Strait Islander people from 2007 to 2010, as well as highlighting areas that require further attention. Hepatitis A disease is now less common in Aboriginal and Torres Strait Islander children than in their non-Indigenous counterparts. Hepatitis A vaccination for Aboriginal and Torres Strait Islander children was introduced in 2005 in the high incidence jurisdictions of the Northern Territory, Queensland, South Australia and Western Australia. In 2002–2005, there were 20 hospitalisations for hepatitis A in Aboriginal and Torres Strait Islander children agedmeningococcal C vaccination for infants and the high-school catch-up program were implemented in 2003, there has been a significant decrease in cases caused by serogroup C. However, the predominant serogroup responsible for disease remains serogroup B, and Aboriginal and Torres Strait Islander children have significantly higher incidence of serogroup B disease than other children. A vaccine against meningococcus type B has now been licensed in Australia. The decline in severe rotavirus disease after vaccine introduction in 2007 was less marked in Aboriginal and Torres Strait Islander children than in other children. By far the highest hospitalisation rates continue to occur among Aboriginal and Torres Strait Islander children in the Northern Territory. Consideration of the role of age cut-offs and 2-dose versus 3-dose schedules may be necessary. Genotype surveillance is critically important to allow detection of any possible emergence of genotypes for which there is lower vaccine-derived immunity. Although Haemophilus influenzae type b disease rates have decreased significantly since the introduction of vaccines in 1993, the plateauing of rates in Aboriginal and Torres Strait Islander children, and increasing disparity with other children, are concerning. While it is possible that higher disease rates in young

    Shell evolution in exotic nuclei is investigated with large-scale shell-model calculations. After presenting that the central and tensor forces produce distinctive ways of shell evolution, we show several recent results: (i) evolution of single-particle-like levels in antimony and cupper isotopes, (ii) shape coexistence in nickel isotopes understood in terms of configuration-dependent shell structure, and (iii) prediction of the evolution of the recently established $N=34$ magic number towards smaller proton numbers. In any case, large-scale shell-model calculations play indispensable roles in describing the interplay between single-particle character and correlation.

    Anecdotal reports have linked cannabis use to violence in some remote Australian Aboriginal communities. We examine the relationship between cannabis use and presentations to local clinics for violence-related trauma at a population level. As part of a larger study, estimates of cannabis and alcohol use status were obtained for 264 randomly selected individuals aged 14-42. These estimates were collected from Aboriginal health workers and respected community informants using a previously validated approach. Clinic records for the sample were audited for physical trauma presentations between January 2004 and June 2006. One in 3 individuals (n = 88/264) presented to the clinic with physical trauma. Of these, the majority (65.9%, n = 58/88) had at least one presentation that was violence-related. Nearly 2 in every 3 of the total presentations for trauma following violence (n = 40/63) involved the use of a weapon. Hunting tools were most often used, followed by wooden or rock implements. Individuals who reported any current cannabis use were nearly 4 times more likely than nonusers to present at least once for violent trauma after adjusting for current alcohol use, age, and sex (OR = 3.8, 95% CI [1.5, 9.8]). Aboriginal individuals in these remote communities experience high rates of physical trauma and violence, often involving weapons. A comprehensive study is needed to explore the association between cannabis and violence. At the same time, an investment in local programmes is needed to address cannabis use and underlying risk factors for substance use and for violence.

    Wurdi Youang is an egg-shaped Aboriginal stone arrangement in Victoria, Australia. Here we present a new survey of the site, and show that its major axis is aligned within a few degrees of east-west. We confirm a previous hypothesis that it contains alignments to the position on the horizon of the setting sun at the equinox and the solstices, and show that two independent sets of indicators are aligned in these directions. We show that these alignments are unlikely to have arisen by chance, and instead the builders of this stone arrangement appear to have deliberately aligned the site on astronomically significant positions.

The purpose of this national study was to explore HIV testing and care decisions of Canadian Aboriginal youth. Methods A community-based mixed-method design incorporating the Aboriginal research principles of Ownership, Control, Access and Possession (OCAP was used. Data were collected through surveys (n = 413 and qualitative interviews (n = 28. Eleven community-based organizations including urban Aboriginal AIDS service organizations and health and friendship centres in seven provinces and one territory assisted with the recruitment of youth (15 to 30 years. Results Average age of survey participants was 21.5 years (median = 21.0 years and qualitative interview participants was 24.4 years (median = 24.0. Fifty-one percent of the survey respondents (210 of 413 youth and 25 of 28 interview participants had been tested for HIV. The most common reason to seek testing was having sex without a condom (43.6% or pregnancy (35.4% while common reasons for not testing were the perception of being low HIV risk (45.3% or not having had sex with an infected person (34.5%. Among interviewees, a contributing reason for not testing was feeling invulnerable. Most surveyed youth tested in the community in which they lived (86.5% and 34.1% visited a physician for the test. The majority of surveyed youth (60.0% had tested once or twice in the previous 2 years, however, about one-quarter had tested more than twice. Among the 26 surveyed youth who reported that they were HIV-positive, 6 (23.1% had AIDS at the time of diagnosis. Delays in care-seeking after diagnosis varied from a few months to seven years from time of test. Conclusion It is encouraging that many youth who had tested for HIV did so based on a realistic self-assessment of HIV risk behaviours; however, for others

    Full Text Available Abstract Background Facilitating the provision of appropriate health care for immigrant and Aboriginal populations in Canada is critical for maximizing health potential and well-being. Numerous reports describe heightened risks of poor maternal and birth outcomes for immigrant and Aboriginal women. Many of these outcomes may relate to food consumption/practices and thus may be obviated through provision of resources which suit the women's ethnocultural preferences. This project aims to understand ethnocultural food and health practices of Aboriginal and immigrant women, and how these intersect with respect to the legacy of Aboriginal colonialism and to the social contexts of cultural adaptation and adjustment of immigrants. The findings will inform the development of visual tools for health promotion by practitioners. Methods/Design This four-phase study employs a case study design allowing for multiple means of data collection and different units of analysis. Phase 1 consists of a scoping review of the literature. Phases 2 and 3 incorporate pictorial representations of food choices (photovoice in Phase 2 with semi-structured photo-elicited interviews (in Phase 3. The findings from Phases 1-3 and consultations with key stakeholders will generate key understandings for Phase 4, the production of culturally appropriate visual tools. For the scoping review, an emerging methodological framework will be utilized in addition to systematic review guidelines. A research librarian will assist with the search strategy and retrieval of literature. For Phases 2 and 3, recruitment of 20-24 women will be facilitated by team member affiliations at perinatal clinics in one of the city's most diverse neighbourhoods. The interviews will reveal culturally normative practices surrounding maternal food choices and consumption, including how women negotiate these practices within their own worldview and experiences.

    2015-01-01

    Smoking prevalence among Aboriginal Australian young people greatly exceeds the prevalence in the broader population of Australian young people, yet limited research has explored the social context in which young Aboriginal Australians smoke. Four focus groups were conducted in 2009 with South Australian Aboriginal smokers aged 15-29 years residing in urban areas (n = 32) to examine attitudes and experiences surrounding smoking and quitting. The primary reasons for smoking initiation and maintenance among Aboriginal Australian young people were identified as stress, social influence and boredom. Motivators for quitting were identified as pregnancy and/or children, sporting performance (males only), cost issues and, to a lesser extent, health reasons. The barriers to cessation were identified as social influence, the perception of quitting as a distant event and reluctance to access cessation support. However, it appears that social influences and stress were particularly salient contributors to smoking maintenance among Aboriginal Australian young people. Smoking cessation interventions targeted at young urban Aboriginal Australian smokers should aim to build motivation to quit by utilising the motivators of pregnancy and/or children, sporting performance (males only), cost issues and, to a lesser extent, health reasons, while acknowledging the pertinent role of social influence and stress in the lives of young urban Aboriginal Australian smokers.

    Developers involved in the field of electric power generation are faced with environmental issues and public misconceptions, in addition to technical and financing issues. The author described the factors that could affect negotiations with Aboriginal peoples during all stages of an electric power generation project. The complexity and location of the project is the major issue of concern, as the rights of Aboriginals in Quebec vary greatly depending on geography. For example, land located north of Val D'Or and Chibougamau is regulated by the James Bay and Northern Quebec Agreement, requiring that a specific process be followed. Aboriginal peoples have different languages and cultures which must be respected in all negotiations. The author emphasized that each Aboriginal community is unique and proposed a few guidelines to help in the negotiation process, namely: (1) knowing the Aboriginal environment of the project, (2) establish contacts with the Aboriginal community, (3) get to know the development characteristics of the Aboriginal community, (4) follow well-defined steps, and, (5) present a proposal in accordance with the type of territory.

  11. Relativistic shell model calculations

    Furnstahl, R. J.

    1986-06-01

    Shell model calculations are discussed in the context of a relativistic model of nuclear structure based on renormalizable quantum field theories of mesons and baryons (quantum hadrodynamics). The relativistic Hartree approximation to the full field theory, with parameters determined from bulk properties of nuclear matter, predicts a shell structure in finite nuclei. Particle-hole excitations in finite nuclei are described in an RPA calculation based on this QHD ground state. The particle-hole interaction is prescribed by the Hartree ground state, with no additional parameters. Meson retardation is neglected in deriving the RPA equations, but it is found to have negligible effects on low-lying states. The full Dirac matrix structure is maintained throughout the calculation; no nonrelativistic reductions are made. Despite sensitive cancellations in the ground state calculation, reasonable excitation spectra are obtained for light nuclei. The effects of including charged mesons, problems with heavy nuclei, and prospects for improved and extended calculations are discussed.

    Full Text Available Abstract Background Little is known about the use of bush medicine and traditional healing among Aboriginal Australians for their treatment of cancer and the meanings attached to it. A qualitative study that explored Aboriginal Australians' perspectives and experiences of cancer and cancer services in Western Australia provided an opportunity to analyse the contemporary meanings attached and use of bush medicine by Aboriginal people with cancer in Western Australia Methods Data collection occurred in Perth, both rural and remote areas and included individual in-depth interviews, observations and field notes. Of the thirty-seven interviews with Aboriginal cancer patients, family members of people who died from cancer and some Aboriginal health care providers, 11 participants whose responses included substantial mention on the issue of bush medicine and traditional healing were selected for the analysis for this paper. Results The study findings have shown that as part of their healing some Aboriginal Australians use traditional medicine for treating their cancer. Such healing processes and medicines were preferred by some because it helped reconnect them with their heritage, land, culture and the spirits of their ancestors, bringing peace of mind during their illness. Spiritual beliefs and holistic health approaches and practices play an important role in the treatment choices for some patients. Conclusions Service providers need to acknowledge and understand the existence of Aboriginal knowledge (epistemology and accept that traditional healing can be an important addition to an Aboriginal person's healing complementing Western medical treatment regimes. Allowing and supporting traditional approaches to treatment reflects a commitment by modern medical services to adopting an Aboriginal-friendly approach that is not only culturally appropriate but assists with the cultural security of the service.

  14. Particles and Shells

    Palazzi, P

    2003-01-01

    The current understanding of particle masses in terms of quarks and their binding energy is not satisfactory. Both in atoms and in nuclei the organizing principle of stability is the shell structure, while this does not seem to play any role for particles. In order to explore the possibility that shells might also be relevant at this inner level of aggregation, atomic and nuclear stability are expressed by "stablines", alignments of the 1/3 power of the total number of constituents of the most stable configurations. Could similar patterns be found in the particle spectrum? By analyzing the distribution of particle lifetimes as a function of mass, stability peaks are recognized for mesons and for baryons and indeed the cube roots of their masses follow two distinct stablines. Such alignments would be a strong indication that the particles themselves are shell structured assuming only that each constituent contributes a constant amount to the total mass. This is incompatible with the prevalent view that the par...

  15. The problem of dementia in Australian aboriginal and Torres Strait Islander communities: an overview.

    Pollitt, P A

    1997-02-01

    The concept of dementia in old age in Australian Aboriginal and Torres Strait Islander communities is intrinsically paradoxical. Firstly, few indigenous people reach old age. Secondly, from some indigenous points of view, dementia is either not recognized as a condition or as a problem, or, in the case of the more disruptive manifestations of cognitive impairment, is perceived as 'madness'. Moreover, in the wider context of profound political, social and economic inequality experienced by most indigenous people, the western medical category of dementia may appear to be of relatively minor importance. However, government initiatives in aged care generally and dementia care in particular which are designed to address the ageing of the Australian population as a whole also include the nation's older indigenous people. This article-based on a review of published work, supplemented by discussions with indigenous and non-indigenous individuals involved in indigenous aged care and mental health-examines some of the issues surrounding cognitive decline in old age for Aborigines and Torres Strait Islanders. More specifically, it looks at the problems involved in assessing and diagnosing cognitive decline and dementia, especially among people who follow more traditional ways of life, and in providing services to sufferers and their carers. In doing so, it considers some of the relative meanings of "old age', "abnormal old age', "mental disorder', "sickness' and "dementia'. PMID:9097208

    1992-10-01

    The frequencies of occurrence of 17 tooth crown traits in the living Ami tribe, which inhabits the east coast of Taiwan, were investigated and compared with other East Asian populations based on Turner's (1987) Mongoloid dental variation theory. Principal coordinate analysis based on Smith's mean measure of divergence using frequencies of the 17 traits suggests that the Ami tribe together with the Yami tribe and the Bunun tribe is included in the sinodont group typical of the Chinese mainland and northeast Asia. In light of these results and the estimated distribution of sinodonty and sundadonty in the past and the present, we speculate that the gene flow from Chinese mainlanders to native sundadonts, who seem to have migrated northward to Taiwan, contributed significantly to the formation of the living Taiwan aboriginal groups, sinodonts. Among the aboriginal tribes of Taiwan, the Ami have characteristics intermediate between those of the Yami and the Bunun. The relative positions of these tribes in East Asian populations suggests that the extent of sinodontification and of genetic isolation is one of the causes of the intertribal variation.

    One of society's top priorities is to reduce the effects of climate change. Since the effects of climate change are more pronounced in polar regions and energy costs are typically very high, Aboriginal and Northern communities have much to gain from improved energy efficiency and the use of renewable energy sources. This publication profiles some of the community-driven energy efficiency and renewable energy projects that were undertaken as part of the Aboriginal and Climate Change Program. The profiles are based on interviews conducted in 2002-2003 with individuals who were instrumental in seeing the projects completed. The projects demonstrated innovative approaches to adopt energy efficiency practices and renewable energy to create a sustainable way of life. The projects ranged from small hydro, wind power, solar energy and district heating with wood. Energy efficiency projects in housing and waste heat recovery were also highlighted. The benefits of the various projects included reduced transportation fuel and energy transmission costs, local employment and reduced greenhouse gas emissions that contribute to climate change. refs., tabs., figs.

  19. Aboriginal overkill in the intermountain west of North America : Zooarchaeological tests and implications.

    Science.gov (United States)

    Lyman, R Lee

    2004-06-01

    Zooarchaeological evidence has often been called on to help researchers determine prehistoric relative abundances of elk (Cervus elaphus) in the Greater Yellowstone ecosystem. Some interpret that evidence as indicating elk were abundant; others interpret it as indicating elk were rare. Wildlife biologist Charles Kay argues that prehistoric faunal remains recovered from archaeological sites support his contention that aboriginal hunters depleted elk populations throughout the Intermountain West, including the Yellowstone area. To support his contention Kay cites differences between modern and prehistoric relative abundances of artiodactyls, age and sex demographics of ungulates in the prehistoric record indicating selective predation of prime-age females, and a high degree of fragmentation of artiodactyl bones indicating humans were under nutritional stress. Kay's data on taxonomic abundances are time and space averaged and thus mask much variation in elk abundances. When these data are not lumped they suggest that elk were at some times, in some places, as abundant as they are today. Data on the age-sex demography of artiodactyl prey are ambiguous or contradict Kay's predictions. Bone fragmentation data are variously nonexistent or ambiguous. The zooarchaeological implications of Kay's aboriginal overkill hypothesis have not yet undergone rigorous testing. PMID:26190412

  20. A 150-Year Conundrum: Cranial Robusticity and Its Bearing on the Origin of Aboriginal Australians

    Directory of Open Access Journals (Sweden)

    Darren Curnoe

    2011-01-01

    Full Text Available The origin of Aboriginal Australians has been a central question of palaeoanthropology since its inception during the 19th Century. Moreover, the idea that Australians could trace their ancestry to a non-modern Pleistocene population such as Homo erectus in Southeast Asia have existed for more than 100 years, being explicitly linked to cranial robusticity. It is argued here that in order to resolve this issue a new program of research should be embraced, one aiming to test the full range of alternative explanations for robust morphology. Recent developments in the morphological sciences, especially relating to the ontogeny of the cranium indicate that character atomisation, an approach underpinning phylogenetic reconstruction, is fraught with difficulties. This leads to the conclusion that phylogenetic-based explanations for robusticity should be reconsidered and a more parsimonious approach to explaining Aboriginal Australian origins taken. One that takes proper account of the complex processes involved in the growth of the human cranium rather than just assuming natural selection to explain every subtle variation seen in past populations. In doing so, the null hypothesis that robusticity might result from phenotypic plasticity alone cannot be rejected, a position at odds with both reticulate and deep-time continuity models of Australian origins.

    Full Text Available Introduction: Addressing systemic barriers experienced by low-income and minority students to accessing medical school, the University of Calgary's Cumming School of Medicine has spearheaded a year-round, mini-med school outreach initiative for Aboriginal students. Method: Junior and senior high school youth generally attend the half-day program in classes or camps of 15–25, breaking into small groups for multisession activities. Undergraduate medical education students mentor the youth in stations offering experiential lessons in physical examination, reading x-rays, and anatomy. All resources from the medical school are offered in-kind, including a pizza lunch at midday, whereas community partners organize transportation for the attendees. Results: Opening the medical school and its resources to the community offers great benefits to resource-constrained schools often limited in terms of science education resources. The model is also an effort to address challenges among the medical professions around attracting and retaining students from underserved populations. Conclusion: The prospect of increasing admission rates and successful completion of medical education among students from marginalized communities poses a real, though difficult-to-measure, possibility of increasing the workforce most likely to return to and work in such challenging contexts. A mini-medical school for Aboriginal youth highlights mutual, long-term benefit for diverse partners, encouraging medical educators and community-based science educators to explore the possibilities for deepening partnerships in their own regions.

    Full Text Available Abstract Background Aboriginal and Torres Strait Islander people with chronic illness confront multiple challenges that contribute to their poor health outcomes, and to the health disparities that exist in Australian society. This study aimed to identify barriers and facilitators to care and support for Aboriginal and Torres Strait Islander people with chronic illness. Methods Face-to-face in-depth interviews were conducted with Aboriginal and Torres Strait Islander people with diabetes, chronic heart failure or chronic obstructive pulmonary disease (n-16 and family carers (n = 3. Interviews were transcribed verbatim and the transcripts were analysed using content analysis. Recurrent themes were identified and these were used to inform the key findings of the study. Results Participants reported both negative and positive influences that affected their health and well-being. Among the negative influences, they identified poor access to culturally appropriate health services, dislocation from cultural support systems, exposure to racism, poor communication with health care professionals and economic hardship. As a counter to these, participants pointed to cultural and traditional knowledge as well as insights from their own experiences. Participants said that while they often felt overwhelmed and confused by the burden of chronic illness, they drew strength from being part of an Aboriginal community, having regular and ongoing access to primary health care, and being well-connected to a supportive family network. Within this context, elders played an important role in increasing people’s awareness of the impact of chronic illness on people and communities. Conclusions Our study indicated that non-Indigenous health services struggled to meet the needs of Aboriginal and Torres Strait Islander people with chronic illness. To address their complex needs, health services could gain considerably by recognising that Aboriginal and Torres Strait

    Full Text Available Abstract Background Despite a lower overall incidence, Aboriginal Australians experience poorer outcomes from cancer compared with the non-Aboriginal population as manifested by higher mortality and lower 5-year survival rates. Lower participation in screening, later diagnosis of cancer, poor continuity of care, and poorer compliance with treatment are known factors contributing to this poor outcome. Nevertheless, many deficits remain in understanding the underlying reasons, with the recommendation of further exploration of Aboriginal beliefs and perceptions of cancer to help understand their care-seeking behavior. This could assist with planning and delivery of more effective interventions and better services for the Aboriginal population. This research explored Western Australian (WA Aboriginal peoples' perceptions, beliefs and understanding of cancer. Methods A total of 37 Aboriginal people from various geographical areas within WA with a direct or indirect experience of cancer were interviewed between March 2006 and September 2007. Interviews were audio-recorded, transcribed verbatim and coded independently by two researchers. NVivo7 software was used to assist data management and analysis. A social constructionist framework provided a theoretical basis for analysis. Interpretation occurred within the research team with member checking and the involvement of an Aboriginal Reference Group assisting with ensuring validity and reliability. Results Outcomes indicated that misunderstanding, fear of death, fatalism, shame, preference for traditional healing, beliefs such as cancer is contagious and other spiritual issues affected their decisions around accessing services. These findings provide important information for health providers who are involved in cancer-related service delivery. Conclusion These underlying beliefs must be specifically addressed to develop appropriate educational, screening and treatment approaches including models of

    We have created an exhibit, Under Southern Skies -- Aboriginal and Western Scientific Perspectives of the Australian Night Sky, which has shown since June, 1999 in newly refurbished exhibit space at the Leander McCormick Observatory. The University of Virginia has a long and continuing tradition of astrometry starting with early parallax work at the McCormick Observatory, extending to our own NSF CAREER Award-funded projects, and including a long-term, ongoing southern parallax program at Mt. Stromlo and Siding Springs Observatories in Australia. Recently, through a gift of Mr. John Kluge, the University of Virginia has obtained one of the most extensive collections of Australian Aboriginal art outside of Australia. The goal of our exhibit is to unite the University's scientific, artistic and cultural connections to Australia through an exhibit focusing on different perspectives of the Australian night sky. We have brought together Australian Aboriginal bark and canvas paintings that feature astronomical themes, e.g., Milky Way, Moon, Magellanic Cloud and Seven Sisters Dreamings, from the Kluge-Ruhe and private collections. These paintings, from the Central Desert and Arnhem Land regions of Australia, are intermingled with modern, large format, color astronomical images of the same scenes. Descriptive panels and a small gallery guide explain the cultural, artistic and scientific aspects of the various thematic groupings based on particular southern hemisphere night sky objects and associated Aboriginal traditions and stories. This unusual combination of art and science not only provides a unique avenue for educating the public about both astronomy and Australian Aboriginal culture, but highlights mankind's ancient and continuing connection to the night sky. We appreciate funding from NSF CAREER Award #AST-9702521, a Cottrell Scholar Award from The Research Corporation, and the Dept. of Astronomy and Ruhe-Kluge Collection at the University of Virginia.

    2011-10-01

    We study the formation of localized structures formed by the point loading of an internally pressurized elastic shell. While unpressurized shells (such as a ping-pong ball) buckle into polygonal structures, we show that pressurized shells are subject to a wrinkling instability. We study wrinkling in depth, presenting scaling laws for the critical indentation at which wrinkling occurs and the number of wrinkles formed in terms of the internal pressurization and material properties of the shell. These results are validated by numerical simulations. We show that the evolution of the wrinkle length with increasing indentation can be understood for highly pressurized shells from membrane theory. These results suggest that the position and number of wrinkles may be used in combination to give simple methods for the estimation of the mechanical properties of highly pressurized shells. © 2011 American Physical Society.

    2013-01-01

    Background: Effective interactions, either derived from microscopic theories or based on fitting selected properties of nuclei in specific mass regions, are widely used inputs to shell-model studies of nuclei. Until recently, most shell-model calculations have been confined to a single oscillator shell. Recent interest in nuclei away from the stability line, requires however larger shell-model spaces. Since the derivation of microscopic effective interactions has been limited to degenerate model spaces, there are both conceptual and practical limits to present shell-model calculations that utilize such interactions. Purpose: The aim of this work is to present a novel microscopic method to calculate effective interactions for the nuclear shell model. Its main difference from existing theories is that it can be applied not only to degenerate model spaces but also to non-degenerate model spaces. Methods: The formalism is presented in the form of many-body perturbation theory based on the recently developed Exten...

    Full Text Available Abstract Background Aboriginal Australians experience poorer outcomes, and are 2.5 times more likely to die from cancer than non-Aboriginal people, even after adjustment for stage of diagnosis, cancer treatment and comorbidities. They are also less likely to present early as a result of symptoms and to access treatment. Psycho-social factors affect Aboriginal people's willingness and ability to participate in cancer-related screening and treatment services, but little exploration of this has occurred within Australia to date. The current research adopted a phenomenological qualitative approach to understand and explore the lived experiences of Aboriginal Australians with cancer and their beliefs and understanding around this disease in Western Australia (WA. This paper details considerations in the design and process of conducting the research. Methods/Design The National Health and Medical Research Council (NHMRC guidelines for ethical conduct of Aboriginal research were followed. Researchers acknowledged the past negative experiences of Aboriginal people with research and were keen to build trust and relationships prior to conducting research with them. Thirty in-depth interviews with Aboriginal people affected by cancer and twenty with health service providers were carried out in urban, rural and remote areas of WA. Interviews were audio-recorded, transcribed verbatim and coded independently by two researchers. NVivo7 software was used to assist data management and analysis. Participants' narratives were divided into broad categories to allow identification of key themes and discussed by the research team. Discussion and conclusion Key issues specific to Aboriginal research include the need for the research process to be relationship-based, respectful, culturally appropriate and inclusive of Aboriginal people.

    Full Text Available Abstract Background While participatory social network analysis can help health service partnerships to solve problems, little is known about its acceptability in cross-cultural settings. We conducted two case studies of chronic illness service partnerships in 2007 and 2008 to determine whether participatory research incorporating social network analysis is acceptable for problem-solving in Australian Aboriginal health service delivery. Methods Local research groups comprising 13–19 partnership staff, policy officers and community members were established at each of two sites to guide the research and to reflect and act on the findings. Network and work practice surveys were conducted with 42 staff, and the results were fed back to the research groups. At the end of the project, 19 informants at the two sites were interviewed, and the researchers conducted critical reflection. The effectiveness and acceptability of the participatory social network method were determined quantitatively and qualitatively. Results Participants in both local research groups considered that the network survey had accurately described the links between workers related to the exchange of clinical and cultural information, team care relationships, involvement in service management and planning and involvement in policy development. This revealed the function of the teams and the roles of workers in each partnership. Aboriginal workers had a high number of direct links in the exchange of cultural information, illustrating their role as the cultural resource, whereas they had fewer direct links with other network members on clinical information exchange and team care. The problem of their current and future roles was discussed inside and outside the local research groups. According to the interview informants the participatory network analysis had opened the way for problem-solving by “putting issues on the table”. While there were confronting and ethically

  17. SHIFTING JUDICIAL CONCEPTIONS OF 'RECONCILIATION': GEOGRAPHIC COMMITMENTS UNDERPINNING ABORIGINAL RIGHTS DECISIONS

    2015-09-01

    Full Text Available Over the course of the past twenty years, the Supreme Court of Canada’s discourse concerning ‘reconciliation’ has shifted from moderating federal power to reconciling the preceding presence of Aboriginal people with an established sovereign (Crown presence.  While scholars postulated that the Court was attempting to maintain colonial relations of power, substantive answers for this discursive shift are lacking within the literature.  This paper provides a comprehensive explanation of this shift by comparing the hearing transcripts in the ‘Aboriginal rights trilogy’ to their corresponding written decisions.  It argues that particular judicial and geographic commitments underlie the concept of ‘reconciliation’ and ultimately serve to represent Aboriginal identity as inescapably ‘Canadian.’   Au cours des vingt dernières années, le discours de la Cour suprême du Canada concernant la « réconciliation » est passé de l’atténuation du pouvoir fédéral à la conciliation entre la présence antérieure des Autochtones et une présence souveraine (de la Couronne établie. Bien que les universitaires aient affirmé que la Cour tentait de maintenir des relations de pouvoir coloniales, l’évolution du discours n’est pas expliquée de façon concrète dans la littérature. Le présent article explique cette évolution de façon détaillée en comparant les transcriptions d’audience dans la « trilogie sur les droits ancestraux » à leurs décisions écrites correspondantes. Il fait valoir que des engagements judiciaires et géographiques particuliers sous-tendent le concept de la « réconciliation » et servent en définitive à représenter l’identité autochtone comme étant inévitablement « canadienne ».

  18. Biodiveristy and Stability of Aboriginal Salmon Fisheries in the Fraser River Watershed

    Science.gov (United States)

    Nesbitt, H. K.; Moore, J.

    2015-12-01

    Natural watersheds are hierarchical networks that may confer stability to ecosystem functions through integration of upstream biodiversity, whereby upstream asset diversification stabilizes the aggregate downstream through the portfolio effect. Here we show that riverine structure and its associated diversity confer stability of salmon catch and lengthened fishing seasons for Aboriginal fisheries on the Fraser River (1370km) in BC, Canada, the second longest dam-free salmon migration route in North America. In Canada, Aboriginal people have rights to fish for food, social, and ceremonial (FSC) purposes. FSC fisheries are located throughout the Fraser watershed and have access to varying levels of salmon diversity based on their location. For instance, fisheries at the mouth of the river have access to all of the salmon that spawn throughout the entire watershed, thus integrating across the complete diversity profile of the entire river. In contrast, fisheries in the headwaters have access to fewer salmon species and populations and thus fish from a much less diverse portfolio. These spatial gradients of diversity within watersheds provide a natural contrast for quantifying the effects of different types of diversity on interannual resource stability and seasonal availability. We acquired weekly and yearly catch totals from 1983 to 2012 (30 years) for Chinook, chum, coho, pink, and sockeye salmon for 21 FSC fishing sites throughout the Fraser River watershed from Fisheries and Oceans Canada. We examined how both population- and species-level diversity affects catch stability and season length at each site by quantifying year-to-year variability and within-year season length respectively. Salmon species diversity made fisheries up to 28% more stable in their catch than predicted with 3.7 more weeks to fish on average. Fisheries with access to high population diversity had up to 3.8 times more stable catch and 3 times longer seasons than less diverse fisheries. We

    2012-08-01

    Full Text Available Abstract Background Early Childhood Caries (ECC is a widespread problem in Australian Aboriginal communities causing severe pain and sepsis. In addition dental services are difficult to access for many Aboriginal children and trying to obtain care can be stressful for the parents. The control of dental caries has been identified as a key indictor in the reduction of Indigenous disadvantage. Thus, there is a need for new approaches to prevent ECC, which reflect the cultural norms of Aboriginal communities. Methods/Design This is a Phase II single arm trial designed to gather information on the effectiveness of a dental health education program for Aboriginal children aged 6 months, followed over 2 years. The program will deliver advice from Aboriginal Health Workers on tooth brushing, diet and the use of fluoride toothpaste to Aboriginal families. Six waves of data collection will be conducted to enable estimates of change in parental knowledge and their views on the acceptability of the program. The Aboriginal Health Workers will also be interviewed to record their views on the acceptability and program feasibility. Clinical data on the child participants will be recorded when they are 30 months old and compared with a reference population of similar children when the study began. Latent variable modeling will be used to interpret the intervention effects on disease outcome. Discussion The research project will identify barriers to the implementation of a family centered Aboriginal oral health strategy, as well as the development of evidence to assist in the planning of a Phase III cluster randomized study.

  2. Natural-Series Radionuclides in Traditional Aboriginal Foods in Tropical Northern Australia: A Review

    Directory of Open Access Journals (Sweden)

    Paul Martin

    2004-01-01

    Full Text Available This paper gives a review of available information on natural-series radionuclides in traditional Aboriginal foods of northern Australia. Research on this topic has been carried out primarily for radiological impact assessment purposes in relation to uranium mining activities in the region. Many of the studies have concentrated on providing purely concentration data or concentration ratios, although more detailed uptake studies have been undertaken for freshwater mussels, turtles, and water lilies. The most-studied radionuclides are 238U and 226Ra. However, dose estimates based on current data highlight the importance of 210Po, particularly for the natural (nonmining-related dose. Data on uptake by terrestrial flora and fauna are scarce in comparison with aquatic organisms, and this knowledge gap will need to be addressed in relation to planning for uranium minesite rehabilitation.

  3. Where culture takes hold: "overimitation" and its flexible deployment in Western, Aboriginal, and Bushmen children.

    2014-01-01

    Children often "overimitate," comprehensively copying others' actions despite manifest perceptual cues to their causal ineffectuality. The inflexibility of this behavior renders its adaptive significance difficult to apprehend. This study explored the boundaries of overimitation in 3- to 6-year-old children of three distinct cultures: Westernized, urban Australians (N = 64 in Experiment 1; N = 19 in Experiment 2) and remote communities of South African Bushmen (N = 64) and Australian Aborigines (N = 19). Children overimitated at high frequency in all communities and generalized what they had learned about techniques and object affordances from one object to another. Overimitation thus provides a powerful means of acquiring and flexibly deploying cultural knowledge. The potency of such social learning was also documented compared to opportunities for exploration and practice.

    Full Text Available Insects and their products have long been used in Indigenous Australian societies as food, medicine and construction material, and given prominent roles in myths, traditional songs and ceremonies. However, much of the available information on the uses of insects in Australia remains anecdotal. In this essay, we review published dictionaries of Aboriginal languages spoken in many parts of Australia, to provide an overview of the Indigenous names and knowledge of insects and their products. We find that that native honeybees and insect larvae (particularly of Lepidoptera and Coleoptera are the most highly prized insects, and should be recognized as cultural keystone species. Many insects mentioned in dictionaries lack scientific identifications, however, and we urge documentary linguists to address this important issue.

  5. Respect for Grizzly Bears: an Aboriginal Approach for Co-existence and Resilience

    D. Scott. Slocombe

    2009-06-01

    Full Text Available Aboriginal peoples’ respect for grizzly bear (Ursus arctos is widely acknowledged, but rarely explored, in wildlife management discourse in northern Canada. Practices of respect expressed toward bears were observed and grouped into four categories: terminology, stories, reciprocity, and ritual. In the southwest Yukon, practices in all four categories form a coherent qualitative resource management system that may enhance the resilience of the bear-human system as a whole. This system also demonstrates the possibility of a previously unrecognized human role in maintaining productive riparian ecosystems and salmon runs, potentially providing a range of valued social-ecological outcomes. Practices of respect hold promise for new strategies to manage bear-human interactions, but such successful systems may be irreducibly small scale and place based.

    Eastwell, H D

    1979-09-01

    Regular petrol-inhaling involves 50 children ("sniffers"), aged nine to 14 years, at the Aboriginal town of Maningrida--over one-third of resident children of this age. Children of two closely related clan-language groups comprise the majority of inhalers. Similarly, at the town of Galiwinku the children of two deprived clans are involved almost exclusively. These are the only clans in eastern Arnhem Land without outstations on their homelands. Revitalization of these clans appears the only effective method of containing the practice. Petrol-inhaling is associated with delinquency, low body weight, venereal disease, and elevated levels of blood lead. The effectiveness of past remedial action is in doubt. PMID:514145

    2001-07-01

    The historical development of First Nations peoples following the conquest of North America, the development of the native reserves system, the creation of a culture of expectancy and the institutionalization of the dependence on welfare and transfer payments, and recent trends in First Nations demographics are sketched. The impact of these factors on First Nations peoples, especially low income, high incidence of substance abuse, high suicide rate among the young, high rate of incarceration, demoralizing loss of confidence, and inward focus, is explored, followed by a series of suggestions as to what can be and what must be done to break the cycle of welfare dependency. Short term solutions include focusing on education and training; longer term term solutions are more complex, but most likely include taking ownership of Aboriginal problems by First Nations peoples themselves, and switching gears from concentrating on grievances to focusing on development issues.

  8. Expert system development (ESD) shell

    International Nuclear Information System (INIS)

    An Expert System Development (ESD) Shell design implementation is desribed in detail. The shell provides high-level generic facilities for Knowledge Representation (KR) and inferencing and tools for developing user interfaces. Powerful set of tools in the shell relieves much of the programming burden in the ES development. The shell is written in PROLOG under IBM PC/AT. KR facilities are based on two very powerful formalisms namely, frames and rules. Inference Engine (IE) draws most of its power from unification and backward reasoning strategy in PROLOG. This basic mechanism is enhanced further by incorporating both forward and backward chaining of rules and frame-based inferencing. Overall programming style integrates multiple paradigms including logic, object oriented, access-oriented and imperative programming. This permits ES designer a lot of flexibility in organizing inference control. Creation and maintainance of knowledge base is a major activity. The shell, therefore, provides number of facilities to simplify these tasks. Shell design also takes note of the fact that final success of any system depends on end-user satisfaction and hence provides features to build use-friendly interfaces. The shell also provides a set of interfacing predicates so that it can be embedded within any PROLOG program to incorporate functionalilty of the shell in the user program.

    Marfan syndrome may affect the cardiovascular, ocular and skeletal systems. The gene for this autosomal dominant disease maps to chromosome 15 and codes for the extracellular matrix protein fibrillin. Phenotypic expression is very variable both within and between families, possibly due to the influence of other, unlinked, genetic factors interacting with the fibrillin gene. We report two Australian families which demonstrate the extent of inter- and intra-family phenotypic variability. Eye, cardiac and skeletal assessments were made independently. In the first family, 8 of 12 siblings and 11 of 19 of their children had ectopia lentis with or without other ocular findings. There were few cardiac signs. One child had mitral valve prolapse. He and three other children had mild dilatation of the aorta. Skeletal abnormalities were also found (3 adults and 7 children). Chest wall asymmetry was the most common skeletal finding. This family has less cardiac and skeletal involvement than is usual in Marfan syndrome, although the disease maps to chromosome 15 in the region of the fibrillin gene (LOD=4.8 at {theta}=0 with respect to CYP19). The second family is partly of Australian aboriginal origin. The disease has been traced through 5 generations. To date we have examined 37 of 84 living members. Twenty-three in 3 generations are affected. Five adults and 4 children have moderate to severe aortic dilatation and there has been at least one death due to aortic dissection. However, two adolescents with subluxed lenses and marked skeletal abnormalities have normal aortic diameters, two children have aortic dilatation without other signs and two children have only subluxed lenses. This family shows the range of phenotypic variation which can arise from mutation in the fibrillin gene, which may be influenced by the admixture of Australian aboriginal genes. These two families provide an invaluable resource for studying genetic interactions in this disease.

    There are many vanishing cultures that possess a wealth of knowledge on the medicinal utility of plants. The Malasars of Dravidian Tamils are an indigenous society occupying the forests of the Western Ghats, South India. They are known to be exceptional healers and keepers of traditional aboriginal knowledge (TAK) of the flora in the Velliangiri holy hills. In fact, their expertise is well known throughout India as evidenced by the thousands of pilgrims that go to the Velliangiri holy hills for healing every year. Our research is the first detailed study of medicinal plants in India that considers variation in TAK among informants using a quantitative consensus analysis. A total of 95 species belonging to 50 families were identified for medicinal and general health purposes. For each species the botanical name, family, local name, parts used, summary of mode of preparation, administration and curing are provided. The consensus analysis revealed a high level of agreement among the informants usage of a particular plant at a local scale. The average consensus index value of an informant was FIC > 0.71, and over 0.80 for some ailments such as respiratory and jaundice. Some of the more common problems faced by the Malasars were gastrointestinal disorders, respiratory illness, dermatological problems and simple illness such as fever, cough, cold, wounds and bites from poisonous animals. We also discovered several new ethnotaxa that have considerable medicinal utility. This study supports claims that the Malasars possess a rich TAK of medicinal plants and that many aboriginals and mainstream people (pilgrims) utilize medicinal plants of the Velliangiri holy hills. Unfortunately, the younger generation of Malasars are not embracing TAK as they tend to migrate towards lucrative jobs in more developed urban areas. Our research sheds some light on a traditional culture that believes that a healthy lifestyle is founded on a healthy environment and we suggest that TAK such as

    Julie Brimblecombe

    Full Text Available BACKGROUND: The cost and dietary choices required to fulfil nutrient recommendations defined nationally, need investigation, particularly for disadvantaged populations. OBJECTIVE: We used optimisation modelling to examine the dietary change required to achieve nutrient requirements at minimum cost for an Aboriginal population in remote Australia, using where possible minimally-processed whole foods. DESIGN: A twelve month cross-section of population-level purchased food, food price and nutrient content data was used as the baseline. Relative amounts from 34 food group categories were varied to achieve specific energy and nutrient density goals at minimum cost while meeting model constraints intended to minimise deviation from the purchased diet. RESULTS: Simultaneous achievement of all nutrient goals was not feasible. The two most successful models (A & B met all nutrient targets except sodium (146.2% and 148.9% of the respective target and saturated fat (12.0% and 11.7% of energy. Model A was achieved with 3.2% lower cost than the baseline diet (which cost approximately AUD$13.01/person/day and Model B at 7.8% lower cost but with a reduction in energy of 4.4%. Both models required very large reductions in sugar sweetened beverages (-90% and refined cereals (-90% and an approximate four-fold increase in vegetables, fruit, dairy foods, eggs, fish and seafood, and wholegrain cereals. CONCLUSION: This modelling approach suggested population level dietary recommendations at minimal cost based on the baseline purchased diet. Large shifts in diet in remote Aboriginal Australian populations are needed to achieve national nutrient targets. The modeling approach used was not able to meet all nutrient targets at less than current food expenditure.

    Full Text Available Abstract Background Rapid change in food intake, physical activity, and tobacco use in recent decades have contributed to the soaring rates of obesity, type 2 diabetes and cardiovascular disease (CVD in Aboriginal populations living in Canada. The nature and influence of contextual factors on Aboriginal health behaviours are not well characterized. Methods To describe the contextual determinants of health behaviours associated with cardiovascular risk factors on the Six Nations reserve, including the built environment, access and affordability of healthy foods, and the use of tobacco. In this cross-sectional study, 63 adults from the Six Nations Reserve completed the modified Neighbourhood Environment Walkability Scale (NEWS, questionnaire assessing food access and availability, tobacco pricing and availability, and the Environmental Profile of Community Health (EPOCH tool. Results The structured environment of Six Nations Reserve scored low for walkability, street connectivity, aesthetics, safety, and access to walking and cycling facilities. All participants purchased groceries off-reserve, although fresh fruits and vegetables were reported to be available and affordable both on and off-reserve. On average $151/week is spent on groceries per family. Ninety percent of individuals report tobacco use is a problem in the community. Tobacco is easily accessible for children and youth, and only three percent of community members would accept increased tobacco taxation as a strategy to reduce tobacco access. Conclusions The built environment, access and affordability of healthy food and tobacco on the Six Nations Reserve are not perceived favourably. Modification of these contextual factors described here may reduce adverse health behaviours in the community.

    Full Text Available Abstract Background In 1987, a prospective study of an Australian Aboriginal Birth Cohort was established focusing on the relationships of fetal and childhood growth with the risk of chronic adult disease. However as the study is being conducted in a highly marginalized population it is also an important resource for cross-sectional descriptive and analytical studies. The aim of this paper is to describe the processes of the third follow up which was conducted 20 years after recruitment at birth. Methods Progressive steps in a multiphase protocol were used for tracing, with modifications for the expected rural or urban location of the participants. Results Of the original 686 cohort participants recruited 68 were untraced and 27 were known to have died. Of the 591 available for examination 122 were not examined; 11 of these were refusals and the remainder were not seen for logistical reasons relating to inclement weather, mobility of participants and single participants living in very remote locations. Conclusion The high retention rate of this follow-up 20 years after birth recruitment is a testament to the development of successful multiphase protocols aimed at overcoming the challenges of tracing a cohort over a widespread remote area and also to the perseverance of the study personnel. We also interpret the high retention rate as a reflection of the good will of the wider Aboriginal community towards this study and that researchers interactions with the community were positive. The continued follow-up of this life course study now seems feasible and there are plans to trace and reexamine the cohort at age 25 years.

  14. A Review of Programs That Targeted Environmental Determinants of Aboriginal and Torres Strait Islander Health

    Directory of Open Access Journals (Sweden)

    Kevin Rowley

    2013-08-01

    Full Text Available Objective: Effective interventions to improve population and individual health require environmental change as well as strategies that target individual behaviours and clinical factors. This is the basis of implementing an ecological approach to health programs and health promotion. For Aboriginal People and Torres Strait Islanders, colonisation has made the physical and social environment particularly detrimental for health. Methods and Results: We conducted a literature review to identify Aboriginal health interventions that targeted environmental determinants of health, identifying 21 different health programs. Program activities that targeted environmental determinants of health included: Caring for Country; changes to food supply and/or policy; infrastructure for physical activity; housing construction and maintenance; anti-smoking policies; increased workforce capacity; continuous quality improvement of clinical systems; petrol substitution; and income management. Targets were categorised according to Miller’s Living Systems Theory. Researchers using an Indigenous community based perspective more often identified interpersonal and community-level targets than were identified using a Western academic perspective. Conclusions: Although there are relatively few papers describing interventions that target environmental determinants of health, many of these addressed such determinants at multiple levels, consistent to some degree with an ecological approach. Interpretation of program targets sometimes differed between academic and community-based perspectives, and was limited by the type of data reported in the journal articles, highlighting the need for local Indigenous knowledge for accurate program evaluation. Implications: While an ecological approach to Indigenous health is increasingly evident in the health research literature, the design and evaluation of such programs requires a wide breadth of expertise, including local Indigenous

    Full Text Available Yolŋu Aboriginal understandings of the body, health, life and sickness, and roles their ancestral epistemologies and knowledge practices play in making agreement have seldom been taken seriously in the biomedical world. In this paper, we describe how insights developed in three different cross-cultural collaborative transdisciplinary research projects led to the design of a digital device aimed at intervening in communicative practices around body, health, life and sickness, interrupting the received practices and assumptions on both sides of the practitioner-client divide. The interrupting device slows down and opens up communication practices potentially leading to mutual understanding, collective agreement making, and bottom-up changes in remote Aboriginal health policy and practice.

    2006-01-01

    This study examined gender differences within a sample of Canadian Aboriginal individuals admitted to an inpatient, hospital-based substance abuse detoxification program. Even though alcohol was the most frequent primary drug of detoxification for both genders, women received proportionately higher rates of cocaine or opiate detoxification diagnoses. In addition to a younger age, females reported higher rates of physical and sexual abuse. Women were also administered antidepressants, antibiotic medication protocols, and more medical evaluation tests. It appears that Canadian Aboriginal women have a diverse set of psychological and medical needs. This study demonstrates the need for detoxification programs to address the substantial rates of intravenous drug use and the associated risk of infectious disease (eg, Hepatitis C, HIV) among this treatment-seeking population.

    Dell, Colleen Anne; Kilty, Jennifer M

    2012-06-14

    This article illustrates how the Aboriginal female drug user is responded to as an expected offender based on the intersection of her gender, race, and class. Drawing on the findings of a national Canadian study documenting the lived experiences of First Nations, Métis, and Inuit female drug users, we argue that the strengthening of cultural identity can potentially disrupt this expected status at both the individual and social system levels. Within the framework of critical victimology, the challenge then becomes to translate this understanding into praxis. In response, we suggest advancing women's agency at the individual level in the face of disempowering images and practices related to the offender, the victim, and Aboriginality. For change at the system level, we return to Christie's notion of the need to dismantle the stereotypical construction of the Aboriginal female drug user. We illustrate both levels of change with an innovative form of knowledge sharing, which aims to evoke transformation with respect to individual and socially constructed conceptualizations of identity.

    The prevalence of antibodies to hepatitis E virus (HEV) has been examined in many countries, but such studies have generally been limited to majority populations such as those represented in healthy blood donors or cross sections of urban populations. Due to its major route of enteric transmission, large differences in HEV prevalence might be expected between populations in the same country but with different living conditions. Using an ELISA based on GST-ORF2.1 antigen, the prevalence of IgG-class antibodies to HEV was examined in three distinct populations in Malaysia: the normal (urban) blood donor population and two aboriginal communities located at Betau, Pahang and Parit Tanjung, Perak. IgG anti-HEV was detected in 45 (44%) of 102 samples from Betau and 15 (50%) of 30 samples from Parit Tanjung, compared to only 2 (2%) of 100 normal blood donors. The distribution of sample ELISA reactivities was also consistent with ongoing sporadic infection in the aboriginal communities, while there was no significant relationship between HEV exposure and age, sex, or malaria infection. The high prevalence of antibodies to HEV in the two aboriginal communities indicates that this group of people are at high risk of exposure to HEV compared to the general blood donors, and the results suggest that studies of HEV seroprevalence within countries must take into account the possibility of widely varying infection rates between populations with marked differences in living conditions.

This event is often considered as the first stage of Reconciliation in Australia. 2007 also marked the 10th Anniversary of the release of the Bringing Them Home Report that highlighted the forced removal of Aboriginal children from their family as part of an assimilation policy. From 1997, the issue of an apology became a sine qua non condition to Reconciliation. It was an important element of the recommendations the Council for Aboriginal Reconciliation submitted to Parliament in 2000. But, Liberal Prime Minister John Howard, in office for more than ten years, refused to say the word “sorry” on the basis that Australians of today are not responsible for the actions of the past and that guilt is not hereditary. His focus was on what is called “practical reconciliation”. Some changes are now on the way as Labor leader, Kevin Rudd, who defeated him at the last federal election in November 24th 2007, has promised to make a formal apology to the stolen generation. Why is it important to say “sorry”? At a time of dramatic developments in Indigenous Affairs, this paper deals with the significance of an apology for Reconciliation in Australia.

    The prevalence of antibodies to hepatitis E virus (HEV) has been examined in many countries, but such studies have generally been limited to majority populations such as those represented in healthy blood donors or cross sections of urban populations. Due to its major route of enteric transmission, large differences in HEV prevalence might be expected between populations in the same country but with different living conditions. Using an ELISA based on GST-ORF2.1 antigen, the prevalence of IgG-class antibodies to HEV was examined in three distinct populations in Malaysia: the normal (urban) blood donor population and two aboriginal communities located at Betau, Pahang and Parit Tanjung, Perak. IgG anti-HEV was detected in 45 (44%) of 102 samples from Betau and 15 (50%) of 30 samples from Parit Tanjung, compared to only 2 (2%) of 100 normal blood donors. The distribution of sample ELISA reactivities was also consistent with ongoing sporadic infection in the aboriginal communities, while there was no significant relationship between HEV exposure and age, sex, or malaria infection. The high prevalence of antibodies to HEV in the two aboriginal communities indicates that this group of people are at high risk of exposure to HEV compared to the general blood donors, and the results suggest that studies of HEV seroprevalence within countries must take into account the possibility of widely varying infection rates between populations with marked differences in living conditions.

    Sexual health indicators for young remote-living Aboriginal women are the worst of all of Australian women. This study aimed to describe and explore young women's behaviour and knowledge in relation to sexual health, as well as to provide health professionals with cross-cultural insights to assist with health practice. A descriptive ethnographic study was conducted, which included: extended ethnographic field work in one remote community over a six-year period; community observation and participation; field notes; semi-structured interviews; group reproductive ethno-physiology drawing and language sessions; focus-group sessions; training and employment of Aboriginal research assistants; and consultation and advice from a local reference group and a Cultural Mentor. Findings reveal that young women in this remote community have a very poor biomedical understanding of sexually transmitted infections and contraception. This is further compounded by not speaking English as a first language, low literacy levels and different beliefs in relation to body functions. In their sexual relationships, young women often report experiences involving multiple casual partners, marijuana use and violence. Together, the findings contribute to a better understanding of the factors underlying sexual health inequity among young Aboriginal women in Australia.

    Aboriginal people of Australia possess a rich knowledge on the use of medicinal plants for the treatment of sores, wounds, and skin infections, ailments which impose a high global disease burden and require effective treatments. The antibacterial and antioxidant activities and phytochemical contents of extracts, obtained from eight medicinal plants used by Aboriginal people of New South Wales, Australia, for the treatment of skin related ailments, were assessed to add value to and provide an evidence-base for their traditional uses. Extracts of Acacia implexa, Acacia falcata, Cassytha glabella, Eucalyptus haemastoma, Smilax glyciphylla, Sterculia quadrifida, and Syncarpia glomulifera were evaluated. All extracts except that of S. quadrifida showed activity against sensitive and multidrug resistant strains of Staphylococcus aureus with minimum inhibitory concentration values ranging from 7.81 to 1000 μg/mL. The sap of E. haemastoma and bark of A. implexa possessed high total phenolic contents (TPC) and strong DPPH radical scavenging abilities. A positive correlation was observed between TPC and free radical scavenging ability. GC-MS analysis of the n-hexane extract of S. glomulifera identified known antimicrobial compounds. Together, these results support the traditional uses of the examined plants for the treatment of skin related ailments and infections by Aboriginal people of New South Wales, Australia.

    2011-01-01

    MicroShell is a lightweight shell environment for engineers and software developers working with embedded microprocessors in Xilinx FPGAs. (MicroShell has also been successfully ported to run on ARM Cortex-M1 microprocessors in Actel ProASIC3 FPGAs, but without project-integration support.) Micro Shell decreases the time spent performing initial tests of field-programmable gate array (FPGA) designs, simplifies running customizable one-time-only experiments, and provides a familiar-feeling command-line interface. The program comes with a collection of useful functions and enables the designer to add an unlimited number of custom commands, which are callable from the command-line. The commands are parameterizable (using the C-based command-line parameter idiom), so the designer can use one function to exercise hardware with different values. Also, since many hardware peripherals instantiated in FPGAs have reasonably simple register-mapped I/O interfaces, the engineer can edit and view hardware parameter settings at any time without stopping the processor. MicroShell comes with a set of support scripts that interface seamlessly with Xilinx's EDK tool. Adding an instance of MicroShell to a project is as simple as marking a check box in a library configuration dialog box and specifying a software project directory. The support scripts then examine the hardware design, build design-specific functions, conditionally include processor-specific functions, and complete the compilation process. For code-size constrained designs, most of the stock functionality can be excluded from the compiled library. When all of the configurable options are removed from the binary, MicroShell has an unoptimized memory footprint of about 4.8 kB and a size-optimized footprint of about 2.3 kB. Since MicroShell allows unfettered access to all processor-accessible memory locations, it is possible to perform live patching on a running system. This can be useful, for instance, if a bug is

    Objective Providing services to rural dwelling minority cultural groups with serious chronic disease is challenging due to access to care and cultural differences. This study aimed to describe service providers’ perspectives on health services delivery for Aboriginal people receiving haemodialysis for end-stage kidney disease in rural Australia. Design Semistructured interviews, thematic analysis Setting A health district in rural New South Wales, Australia Participants Using purposive sampling, 29 renal and allied service providers were recruited, including nephrologists, renal nurses, community nurses, Aboriginal health workers, social workers and managers. Six were Aboriginal and 23 non-Aboriginal. Results Improving cultural understanding within the healthcare system was central to five themes identified: rigidity of service design (outreach, inevitable home treatment failures, pressure of system overload, limited efficacy of cultural awareness training and conflicting priorities in acute care); responding to social complexities (respecting but challenged by family obligations, assumptions about socioeconomic status and individualised care); promoting empowerment, trust and rapport (bridging gaps in cultural understanding, acknowledging the relationship between land, people and environment, and being time poor); distress at late diagnosis (lost opportunities and prioritise prevention); and contending with discrimination and racism (inherent judgement of lifestyle choices, inadequate cultural awareness, pervasive multilevel institutionalised racism and managing patient distrust). Conclusions Service providers believe current services are not designed to address cultural needs and Aboriginality, and that caring for Aboriginal patients receiving haemodialysis should be family focused and culturally safer. An Aboriginal-specific predialysis pathway, building staff cultural awareness and enhancing cultural safety within hospitals are the measures recommended

    Salmonella is the most important human pathogen associated with shell eggs. Salmonella Enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. Many sample methods are used to recover microorganisms from eggshells and membranes. A shell rinse and modified shell-and-membrane crush method for recovery of Salmonella were compared. Eggs were collected from 3 commercial shell-washing facilities (X, Y, and Z) during 3 visits. Twelve eggs were collected from each of 10 to 12 locations along the egg processing chain. After being transported back to the laboratory, each egg was sampled first by a shell rinse method and then by a shell crush method. For each technique (rinse or crush), 2 pools of 5 eggs per location sampled were selectively enriched for the recovery of Salmonella. Presumptive samples positive for Salmonella were confirmed serologically. Overall, there were 10.1% (40/396) Salmonella-positive pooled samples. Salmonella were recovered by the shell rinse and shell crush techniques (4.8 vs. 5.3%, respectively). Plant X yielded 21.5% Salmonella positives, whereas less than 5% of samples from plants Y and Z were found to be contaminated with the organism (4.2 and 4.5%, respectively). Salmonella was recovered more often from unwashed eggs (15.8%) than from washed eggs (8.3%). For some eggs, Salmonella was only recovered by one of the methods. Use of both approaches in the same experiment increased sampling sensitivity, although in most cases, crushing provided more sensitive Salmonella recovery. PMID:16479955

    Full Text Available EnglishThe transition from traditional high to modern low fertility is in the forefront of empirical and theoretical investigations in contemporary aboriginal demography.The challenging question therein remains why its fertility has started to decline a century or so after the rest of Canada, and why it continues to trail the latter by a considerable lag. The objective of this paper is to present a history-based explanatory framework of the childbearing behaviour of Canadian aboriginal peoples, as it has evolved over time from the very first contact with Europeans to our day. Turning to existing theories for possible elucidation of these idiosyncrasies, we find that while accounting for certain aspects, they leave others unexplained. History provides a more satisfying explanation when we cast an eye not on the “abstract” population, “ideal-type” or what we today like to call “model”, but on real population, or family thereof, in its spatio-temporal context. The “between-two-cultures” paradigm presented here, based on ethnocentricity and dependency, could be seen as a an explanatory paradigm of competing forces on the Canadian aboriginals: on the one hand, those pushing toward modern norms of childbearing; and on the other, traditional values and structures, as shattered as they are, with their pro-natalist ideologies resisting normative changes.FrenchLa transition de la fécondité de son niveau traditionnel élevé à son niveaumoderne faible est au centre même des préoccupations théoriques etempiriques de la démographie contemporaine des peoples autochtones duCanada.

  2. Isogeometric shell formulation based on a classical shell model

    2012-09-04

    This paper constitutes the first steps in our work concerning isogeometric shell analysis. An isogeometric shell model of the Reissner-Mindlin type is introduced and a study of its accuracy in the classical pinched cylinder benchmark problem presented. In contrast to earlier works [1,2,3,4], the formulation is based on a shell model where the displacement, strain and stress fields are defined in terms of a curvilinear coordinate system arising from the NURBS description of the shell middle surface. The isogeometric shell formulation is implemented using the PetIGA and igakit software packages developed by the authors. The igakit package is a Python package used to generate NURBS representations of geometries that can be utilised by the PetIGA finite element framework. The latter utilises data structures and routines of the portable, extensible toolkit for scientific computation (PETSc), [5,6]. The current shell implementation is valid for static, linear problems only, but the software package is well suited for future extensions to geometrically and materially nonlinear regime as well as to dynamic problems. The accuracy of the approach in the pinched cylinder benchmark problem and present comparisons against the h-version of the finite element method with bilinear elements. Quadratic, cubic and quartic NURBS discretizations are compared against the isoparametric bilinear discretization introduced in [7]. The results show that the quadratic and cubic NURBS approximations exhibit notably slower convergence under uniform mesh refinement as the thickness decreases but the quartic approximation converges relatively quickly within the standard variational framework. The authors future work is concerned with building an isogeometric finite element method for modelling nonlinear structural response of thin-walled shells undergoing large rigid-body motions. The aim is to use the model in a aeroelastic framework for the simulation of flapping wings.

    Full Text Available Abstract There are many vanishing cultures that possess a wealth of knowledge on the medicinal utility of plants. The Malasars of Dravidian Tamils are an indigenous society occupying the forests of the Western Ghats, South India. They are known to be exceptional healers and keepers of traditional aboriginal knowledge (TAK of the flora in the Velliangiri holy hills. In fact, their expertise is well known throughout India as evidenced by the thousands of pilgrims that go to the Velliangiri holy hills for healing every year. Our research is the first detailed study of medicinal plants in India that considers variation in TAK among informants using a quantitative consensus analysis. A total of 95 species belonging to 50 families were identified for medicinal and general health purposes. For each species the botanical name, family, local name, parts used, summary of mode of preparation, administration and curing are provided. The consensus analysis revealed a high level of agreement among the informants usage of a particular plant at a local scale. The average consensus index value of an informant was FIC > 0.71, and over 0.80 for some ailments such as respiratory and jaundice. Some of the more common problems faced by the Malasars were gastrointestinal disorders, respiratory illness, dermatological problems and simple illness such as fever, cough, cold, wounds and bites from poisonous animals. We also discovered several new ethnotaxa that have considerable medicinal utility. This study supports claims that the Malasars possess a rich TAK of medicinal plants and that many aboriginals and mainstream people (pilgrims utilize medicinal plants of the Velliangiri holy hills. Unfortunately, the younger generation of Malasars are not embracing TAK as they tend to migrate towards lucrative jobs in more developed urban areas. Our research sheds some light on a traditional culture that believes that a healthy lifestyle is founded on a healthy environment and

    Full Text Available Abstract Background The goal of this cluster randomized trial is to test the effectiveness of a counseling approach, Motivational Interviewing, to control dental caries in young Aboriginal children. Motivational Interviewing, a client-centred, directive counseling style, has not yet been evaluated as an approach for promotion of behaviour change in indigenous communities in remote settings. Methods/design Aboriginal women were hired from the 9 communities to recruit expectant and new mothers to the trial, administer questionnaires and deliver the counseling to mothers in the test communities. The goal is for mothers to receive the intervention during pregnancy and at their child's immunization visits. Data on children's dental health status and family dental health practices will be collected when children are 30-months of age. The communities were randomly allocated to test or control group by a random "draw" over community radio. Sample size and power were determined based on an anticipated 20% reduction in caries prevalence. Randomization checks were conducted between groups. Discussion In the 5 test and 4 control communities, 272 of the original target sample size of 309 mothers have been recruited over a two-and-a-half year period. A power calculation using the actual attained sample size showed power to be 79% to detect a treatment effect. If an attrition fraction of 4% per year is maintained, power will remain at 80%. Power will still be > 90% to detect a 25% reduction in caries prevalence. The distribution of most baseline variables was similar for the two randomized groups of mothers. However, despite the random assignment of communities to treatment conditions, group differences exist for stage of pregnancy and prior tooth extractions in the family. Because of the group imbalances on certain variables, control of baseline variables will be done in the analyses of treatment effects. This paper explains the challenges of conducting

    Full Text Available Abstract Background Aboriginal children in Canada are at increased risk for type 2 diabetes. Given that physical inactivity is an important modifiable risk factor for type 2 diabetes, prevention efforts targeting Aboriginal children include interventions to enhance physical activity involvement. These types of interventions require adequate assessment of physical activity patterns to identify determinants, detect trends, and evaluate progress towards intervention goals. The purpose of this study was to develop a culturally appropriate interactive computer program to self-report physical activity for Kanien'kehá:ka (Mohawk children that could be administered in a group setting. This was an ancillary study of the ongoing Kahnawake Schools Diabetes Prevention Project (KSDPP. Methods During Phase I, focus groups were conducted to understand how children describe and graphically depict type, intensity and duration of physical activity. Sixty-six students (40 girls, 26 boys, mean age = 8.8 years, SD = 1.8 from four elementary schools in three eastern Canadian Kanien'kehá:ka communities participated in 15 focus groups. Children were asked to discuss and draw about physical activity. Content analysis of focus groups informed the development of a school-day and non-school-day version of the physical activity interactive recall (PAIR. In Phase II, pilot-tests were conducted in two waves with 17 and 28 children respectively to assess the content validity of PAIR. Observation, videotaping, and interviews were conducted to obtain children's feedback on PAIR content and format. Results Children's representations of activity type and activity intensity were used to compile a total of 30 different physical activity and 14 non-physical activity response choices with accompanying intensity options. Findings from the pilot tests revealed that Kanien'kehá:ka children between nine and 13 years old could answer PAIR without assistance. Content validity of PAIR was

    Tinea of the skin and nails is a common problem in remote Aboriginal communities of the Top End of Australia. A retrospective study was performed on data collected from 104 patients from several indigenous communities. Worksheets were filled in by district medical officers and rural general practitioners, detailing the extent of the tinea. Patients were prescribed between 4 and 12 weeks of 250 mg daily oral terbinafine. Fifty-two patients were followed up, with 45 having a good response to treatment (87%) and with 22 of these patients having full clearance of tinea (42%). A prospective study with 44 subjects was performed. The extent of the tinea was documented and fungal scrapings/clippings were taken. Forty subjects were recruited and given oral terbinafine (2-12 weeks depending on skin/nail involvement) or topical terbinafine if oral treatment was contraindicated. Twenty-five of the 40 (63%) subjects were reviewed. Twenty-three (92%) subjects that were followed up improved clinically, with 8/25 (32%) clearing completely. Twenty (80%) of followed-up patients complied fully with treatment. Terbinafine was found to be a well-tolerated and effective treatment of tinea of the skin and nails. PMID:14616489

    The Australian health care system is currently in a state of reform and there is increasing pressure to provide care in community settings. Rising costs, demands and population ageing underscore the importance of adopting models of health care delivery to address changing epidemiological patterns. Population ageing and the increase of chronic conditions challenge models based on acute care. Changes to the Medicare benefits schedule have facilitated the development of a range of expanded nursing services in the general practice setting. In particular, item number 10997 was introduced to reimburse practice nurses and Aboriginal health workers (AHWs) for providing monitoring and support to people with a chronic disease for and on behalf of a general practitioner (GP). The uptake of Medicare Item 100997 from 2007 to 2009, to monitor chronic disease interventions provided by general practice nurses has increased dramatically. The rate of uptake of Item 100997 has not been consistent across States and Territories, even allowing for population distributions. Exploring reasons for these regional variations and linking uptake of Medicare Item numbers to patient outcomes is important in developing the nursing role in Australian general practice.

    Collaborative problem solving has increasingly become important in the face of the complexities in the management of resources, including protected areas. The strategy undertaken by Girringun Aboriginal Corporation in north tropical Queensland, Australia, for developing co-management demonstrates the potential for a problem solving approach involving sequential initiatives, as an alternative to the more familiar negotiated agreements for co-management. Our longitudinal case study focuses on the development of indigenous ranger units as a strategic mechanism for the involvement of traditional owners in managing their country in collaboration with government and other interested parties. This was followed by Australia's first traditional use of marine resources agreement, and development of a multi-jurisdictional, land to sea, indigenous protected area. In using a relationship building approach to develop regional scale co-management, Girringun has been strengthening its capabilities as collaborator and regional service provider, thus, bringing customary decision-making structures into play to 'care for country'. From this evolving process we have identified the key components of a relationship building strategy, 'the pillars of co-management'. This approach includes learning-by-doing, the building of respect and rapport, sorting out responsibilities, practical engagement, and capacity-building.

    Full Text Available The one constant of librarianship is the inevitability of interaction with diverse populations throughout all facets of the profession. This literature review critically examines works on the education and participation of North American Aboriginal people in the profession of librarianship and outlines the evolution of recruitment and retention strategies as they are addressed in scholarly literature. The authors pay particular attention to Canada where Aboriginal people have, historically, constituted an under-served and understudied demographic in the field of Library and Information Studies (LIS. The authors note that much LIS literature on diversity tackles the subject in its broadest scope; even authors specifically addressing race tend to focus on all visible minorities and ignore those factors specific to Aboriginal people. Those who do examine the topic in a more targeted fashion discuss the barriers that discourage Aboriginal people from pursuing librarianship, and touch on the varying levels of success achieved by a variety of recruitment strategies. As many of these recruitment tactics have proven inadequate, educators and academics have begun to explore the necessity of infusing diversity education throughout LIS curricula and - going further - indigenizing academia. In more recent scholarship, the fundamental bias of western education is increasingly discussed, and recruitment literature now reflects the need to foster an academic environment where alternate methodologies and epistemologies are used and respected, rather than studied as the historic relics of a stagnant culture.

    The epidemiology and environmental factors affecting transmission of human microsporidiosis are poorly understood. We conducted the present study to determine the prevalence and risk factors associated with asymptomatic intestinal microsporidiosis among aboriginal school children in the Kuala Krau District, Pahang State, Malaysia. We collected stool samples from 255 school children and examined the samples using Gram-chromotrope Kinyoun stain. We also collected demographic, socioeconomic, environmental and personal hygiene information using a pre-tested questionnaire. Sixty-nine of the children was positive for microsporidia: 72.5% and 27.5% were low (1+) and moderate (2+) excretions of microsporidia spores, respectively. Univariate and multivariate analyses showed being aged 10 years (p = 0.026), using an unsafe water supply as a source for drinking water (p = 0.044) and having close contact with domestic animals (p = 0.031) were all significantly associated with microsporidial infection among study subjects. Our findings suggest asymptomatic intestinal microsporidiosis is common in the study population, more than previously reported. In the study population, control measures need to be implemented, such as good personal hygiene, proper sanitation and safe drinking water supply. PMID:27405127

    The study of traversable wormholes is very hot topic for the past 30 years. One of the best possible way to make traversable wormhole is using the thin-shells to cut and paste two spacetime which has tunnel from one region of space-time to another, through which a traveler might freely pass in wormhole throat. These geometries need an exotic matter which involves a stress-energy tensor that violates the null energy condition. However, this method can be used to minimize the amount of the exotic matter. The goal of this thesis study is to study on thin-shell and thin-shell wormholes in general relativity in 2+1 and 3+1 dimensions. We also investigate the stability of such objects.

    Full Text Available Abstract Background Despite continuous efforts by the government and private sectors, malaria is still a public health problem in rural Peninsular Malaysia. This study investigated household knowledge, attitude and practices (KAP regarding malaria in two malaria endemic communities, forest-aboriginal and rural communities, in the Lipis district of Pahang state, Malaysia. Methods A descriptive cross-sectional study with a semi-structured questionnaire was carried out among 100 and 123 households from forest-aboriginal and rural areas, respectively. Results Knowledge about malaria and its transmission is significantly higher among the rural participants than the aborigines (86.2% vs 76%, p Conclusions Both communities were aware of malaria as a disease, but knowledge, attitudes and practices were inadequate. Providing efficient health education to people residing in malaria endemic areas would improve their understanding about malaria prevention in order to bring about the elimination of malaria from the country.

    Full Text Available Abstract Background Despite clear evidence regarding how social determinants of health and structural inequities shape health, Aboriginal women’s birth outcomes are not adequately understood as arising from the historical, economic and social circumstances of their lives. The purpose of this study was to understand rural Aboriginal women’s experiences of maternity care and factors shaping those experiences. Methods Aboriginal women from the Nuxalk, Haida and 'Namgis First Nations and academics from the University of British Columbia in nursing, medicine and counselling psychology used ethnographic methods within a participatory action research framework. We interviewed over 100 women, and involved additional community members through interviews and community meetings. Data were analyzed within each community and across communities. Results Most participants described distressing experiences during pregnancy and birthing as they grappled with diminishing local maternity care choices, racism and challenging economic circumstances. Rural Aboriginal women’s birthing experiences are shaped by the intersections among rural circumstances, the effects of historical and ongoing colonization, and concurrent efforts toward self-determination and more vibrant cultures and communities. Conclusion Women’s experiences and birth outcomes could be significantly improved if health care providers learned about and accounted for Aboriginal people’s varied encounters with historical and ongoing colonization that unequivocally shapes health and health care. Practitioners who better understand Aboriginal women’s birth outcomes in context can better care in every interaction, particularly by enhancing women’s power, choice, and control over their experiences. Efforts to improve maternity care that account for the social and historical production of health inequities are crucial.

    Full Text Available Abstract Background Problems with substance use are common in some Aboriginal communities. Although problems with substance use are associated with significant mortality and morbidity, many people who experience them do not seek help. Training in mental health first aid has been shown to be effective in increasing knowledge of symptoms and behaviours associated with seeking help. The current study aimed to develop culturally appropriate guidelines for providing mental health first aid to an Aboriginal or Torres Strait Islander person who is experiencing problem drinking or problem drug use (e.g. abuse or dependence. Methods Twenty-eight Aboriginal health experts participated in two independent Delphi studies (n = 22 problem drinking study, n = 21 problem drug use; 15 participated in both. Panellists were presented with statements about possible first aid actions via online questionnaires and were encouraged to suggest additional actions not covered by the content. Statements were accepted for inclusion in the guidelines if they were endorsed by ≥ 90% of panellists as either 'Essential' or 'Important'. At the end of the two Delphi studies, participants were asked to give feedback on the value of the project and their participation experience. Results From a total of 735 statements presented over two studies, 429 were endorsed (223 problem drinking, 206 problem drug use. Statements were grouped into sections based on common themes (n = 7 problem drinking, n = 8 problem drug use, then written into guideline documents. Participants evaluated the Delphi method employed, and the guidelines developed, as useful and appropriate for Aboriginal and Torres Strait Islander people. Conclusions Aboriginal health experts were able to reach consensus about culturally appropriate first aid for problems with substance use. Many first aid actions endorsed in the current studies were not endorsed in previous international Delphi studies, conducted on problem

  16. Shell Models of Magnetohydrodynamic Turbulence

    Plunian, Franck; Frick, Peter

    2012-01-01

    Shell models of hydrodynamic turbulence originated in the seventies. Their main aim was to describe the statistics of homogeneous and isotropic turbulence in spectral space, using a simple set of ordinary differential equations. In the eighties, shell models of magnetohydrodynamic (MHD) turbulence emerged based on the same principles as their hydrodynamic counter-part but also incorporating interactions between magnetic and velocity fields. In recent years, significant improvements have been made such as the inclusion of non-local interactions and appropriate definitions for helicities. Though shell models cannot account for the spatial complexity of MHD turbulence, their dynamics are not over simplified and do reflect those of real MHD turbulence including intermittency or chaotic reversals of large-scale modes. Furthermore, these models use realistic values for dimensionless parameters (high kinetic and magnetic Reynolds numbers, low or high magnetic Prandtl number) allowing extended inertial range and accu...

  17. Asymptotic safety goes on shell

    International Nuclear Information System (INIS)

    It is well known in quantum field theory that the off-shell effective action depends on the gauge choice and field parametrization used in calculating it. Nevertheless, the typical scheme in which the scenario of asymptotically safe gravity is investigated is an off-shell version of the functional renormalization group equation. Working with the Einstein-Hilbert truncation as a test bed, we develop a new scheme for the analysis of asymptotically safe gravity in which the on-shell part of the effective action is singled out and we show that the beta function for the essential coupling has no explicit gauge dependence. In order to reach our goal, we introduce several technical novelties, including a different decomposition of the metric fluctuations, a new implementation of the ghost sector and a new cut-off scheme. We find a nontrivial fixed point, with a value of the cosmological constant that is independent of the gauge-fixing parameters. (paper)

    2002-05-01

    One of the theories of the electronic stopping power S for fast light ions was derived by Bethe. The algorithm currently used for the calculation of S includes terms known as the mean excitation energy I, the shell correction, the Barkas correction, and the Bloch correction. These terms are described here. For the calculation of the shell corrections an atomic model is used, which is more realistic than the hydrogenic approximation used so far. A comparison is made with similar calculations in which the local plasma approximation is utilized. Close agreement with the experimental data for protons with energies from 0.3 to 10 MeV traversing Al and Si is found without the need for adjustable parameters for the shell corrections.

    Full Text Available Abstract Background Low back pain (LBP is the most prevalent musculo-skeletal condition in rural and remote Australian Aboriginal communities. Smoking, physical inactivity and obesity are also prevalent amongst Indigenous people contributing to lifestyle diseases and concurrently to the high burden of low back pain. Objectives This paper aims to examine the association between LBP and modifiable risk factors in a large rural Indigenous community as a basis for informing a musculo-skeletal and related health promotion program. Methods A community Advisory Group (CAG comprising Elders, Aboriginal Health Workers, academics, nurses, a general practitioner and chiropractors assisted in the development of measures to assess self-reported musculo-skeletal conditions including LBP risk factors. The Kempsey survey included a community-based survey administered by Aboriginal Health Workers followed by a clinical assessment conducted by chiropractors. Results Age and gender characteristics of this Indigenous sample (n = 189 were comparable to those reported in previous Australian Bureau of Statistics (ABS studies of the broader Indigenous population. A history of traumatic events was highly prevalent in the community, as were occupational risk factors. Thirty-four percent of participants reported a previous history of LBP. Sporting injuries were associated with multiple musculo-skeletal conditions, including LBP. Those reporting high levels of pain were often overweight or obese and obesity was associated with self-reported low back strain. Common barriers to medical management of LBP included an attitude of being able to cope with pain, poor health, and the lack of affordable and appropriate health care services. Though many of the modifiable risk factors known to be associated with LBP were highly prevalent in this study, none of these were statistically associated with LBP. Conclusion Addressing particular modifiable risk factors associated with LBP

    2016-01-01

    In Canada, diabetes is 3 to 5 times more common among Aboriginal people than in the general population. Women with a diagnosis of gestational diabetes mellitus have an increased risk of developing glucose intolerance later in life, with almost half developing type II diabetes within 15 years. A participatory action research study using a Two-Eyed Seeing approach was conducted. Conversational interviews with 9 Mi'kmaq women who experienced gestational diabetes mellitus and talking circles were held. Hermeneutic phenomenology was used for data analysis. Themes included life-altering experience; barriers limiting access to health care; social support during pregnancy; and feeling compelled to take action. PMID:27149230

    A social marketing campaign promoting hand-washing with soap was implemented to reduce the high burden of infection experienced by Australian Aboriginal children living in remote communities. Epidemiological evidence of effect and other evidence were used to identify the hygiene intervention and health promotion approach for the project. We drew on the findings of: (i) a systematic literature review to identify the intervention for which there is strong effect in similar populations and contexts; and (ii) a narrative literature review to determine our health promotion approach. This process provided practitioners with confidence and understanding so they could address a complex problem in a politically and otherwise sensitive context. PMID:21721304

    Carica papaya leaf decoction, an Australian Aboriginal remedy, has been used widely for its healing capabilities against cancer, with numerous anecdotal reports. In this study we investigated its in vitro cytotoxicity on human squamous cell carcinoma cells followed by metabolomic profiling of Carica papaya leaf decoction and leaf juice/brewed leaf juice to determine the effects imparted by the long heating process typical of the Aboriginal remedy preparation. MTT assay results showed that in comparison with the decoction, the leaf juice not only exhibited a stronger cytotoxic effect on SCC25 cancer cells, but also produced a significant cancer-selective effect as shown by tests on non-cancerous human keratinocyte HaCaT cells. Furthermore, evidence from testing brewed leaf juice on these two cell lines suggested that the brewing process markedly reduced the selective effect of Carica papaya leaf on SCC25 cancer cells. To tentatively identify the compounds that contribute to the distinct selective anticancer activity of leaf juice, an untargeted metabolomic approach employing Ultra High Performance Liquid Chromatography-Quadrupole Time of Flight-Mass Spectrometry followed by multivariate data analysis was applied. Some 90 and 104 peaks in positive and negative mode respectively were selected as discriminatory features from the chemical profile of leaf juice and >1500 putative compound IDs were obtained via database searching. Direct comparison of chromatographic and tandem mass spectral data to available reference compounds confirmed one feature as a match with its proposed authentic standard, namely pheophorbide A. However, despite pheophorbide A exhibiting cytotoxic activity on SCC25 cancer cells, it did not prove to be the compound contributing principally to the selective activity of leaf juice. With promising results suggesting stronger and more selective anticancer effects when compared to the Aboriginal remedy, Carica papaya leaf juice warrants further study

    Full Text Available This article reviews the assumptions that underpin thecommonly implemented Chronic Disease Self-Managementmodels. Namely that there are a clear set of instructions forpatients to comply with, that all health care providers agreewith; and that the health care provider and the patient agreewith the chronic disease self-management plan that wasdeveloped as part of a consultation. These assumptions areevaluated for their validity in the remote health care context,particularly for Aboriginal people. These assumptions havebeen found to lack validity in this context, therefore analternative model to enhance chronic disease care isproposed.

  11. Statistical mechanics of thin spherical shells

    CERN Document Server

    Kosmrlj, Andrej

    2016-01-01

    We explore how thermal fluctuations affect the mechanics of thin amorphous spherical shells. In flat membranes with a shear modulus, thermal fluctuations increase the bending rigidity and reduce the in-plane elastic moduli in a scale-dependent fashion. This is still true for spherical shells. However, the additional coupling between the shell curvature, the local in-plane stretching modes and the local out-of-plane undulations, leads to novel phenomena. In spherical shells thermal fluctuations produce a radius-dependent negative effective surface tension, equivalent to applying an inward external pressure. By adapting renormalization group calculations to allow for a spherical background curvature, we show that while small spherical shells are stable, sufficiently large shells are crushed by this thermally generated "pressure". Such shells can be stabilized by an outward osmotic pressure, but the effective shell size grows non-linearly with increasing outward pressure, with the same universal power law expone...

    A population genetic study was undertaken to provide gene frequency data on the additional blood genetic markers in the Semai and to estimate the genetic relations between the Semai and their neighboring and linguistically related populations by genetic distance and principal components analyses. Altogether 10 polymorphic and 7 monomorphic blood genetic markers (plasma proteins and red cell enzymes) were studied in a group of 349 Senoi Semai from 11 aboriginal settlements (villages) in the Pahang State of western Malaysia. Both the red cell glucose-6-phosphate dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase (PGD) loci reveal the presence of polymorphic frequencies of a nondeficient slow allele at the G6PD locus and a fast allele at the PGD locus. The Semai are characterized by high prevalences of ahaptoglobinemia and G6PD deficiency, high frequencies of HP*1, HB*E, RH*R1, ACP*C, GLO1*1, PGM1*2+, and GC*1F and corresponding low frequencies of ABO*A, HbCoSp, HB*B0, TF*D, CHI, and GC*2. Genetic distance analyses by both cluster and principal components models were performed between the Semai and 14 other populations (Malay; Javanese; Khmer; Veddah; Tamils of Malaysia, Sri Lanka, and India; Sinhalese; Oraon; Toda and Irula of India; Chinese; Japanese; Koreans) on the basis of 30 alleles at 7 polymorphic loci. A more detailed analysis using 53 alleles at 13 polymorphic loci with 10 populations was carried out. Both analyses give genetic evidence of a close relationship between the Semai and the Khmer of Cambodia. Furthermore, the Semai are more closely related to the Javanese than to their close neighbors--the Malay, Chinese, and Tamil Indians. There is no evidence for close genetic relationship between the Semai and the Veddah or other Indian tribes. The evidence fits well with the linguistic relationship of the Semai with the Mon-Khmer branch of the Austro-Asiatic language family.

  13. Development opportunities for northern aboriginal communities from Saskatchewan's uranium mining industry

    International Nuclear Information System (INIS)

    A. Richards, a public relations specialist from Cogema Resources Inc., discussed the programmes for human resource and community development in northern Saskatchewan. This region has the world's largest known high-grade deposits of uranium as well as a high level of provincial, public and northern community support. A mainly Aboriginal population of around 35 000 with a very high proportion of young persons entering the work force, lives in small, dispersed communities in a landscape of forest and lakes. All of the uranium mines are in remote locations with 'local impact' communities often several hundred kilometres away. In the late 1970's a public board of inquiry set none operating conditions that included maximizing opportunities for northern business and employment. Dozens of joint initiatives have since been developed and resulted in innovative hiring, training and transportation programmes, as well as support programmes to improve health, education, professional and business development and quality of life in the communities. Residents of northern Saskatchewan, like all other Canadians, are not prepared to accept environmental risks in return for economic opportunities. Three regional Environmental Quality Committees, with representatives froth all of the northern communities, work with Provincial agencies and the uranium mining industry to ensure community concerns are included in decisions. Northern hunters and fishermen, whose close links with the land are respected, provide relevant data to the Environmental Monitoring Program. Mutual trust is developed through constant interaction and dialogue in one-to-one relationships. Traditional activities like trapping are given their full importance. A Community Vitality Project jointly monitors social well being as defined by northern interests and culture. Compensations and company donations in some cases provide resources for community activities. (author)

    Objective: To evaluate the antimicrobial potency of 20 non-edible and/or poisonous plants used by an aborigine tribe (Kandha) of Kalahandi district for infectious diseases. Methods: Over a period of 5 months from two hospitals, 10 pathogenic bacteria (Staphylococcus aureus (S. aureus), Acinetobacter sp., Citrobacter freundii (C. freundii), Chromobacterium violeceum (C. violeceum),Escherichia coli (E. coli), Klebsiella sp., Proteus sp., Pseudomonas aeruginosa (P. aeruginosa) Salmonella typhi (S. typhi) and Vibrio cholerae (V. cholerae) were isolated to pure axenic cultures from clinical samples. Water and ethanolic extracts of leaves and barks were concentrated before monitoring antimicrobial activity by agar-well diffusion method. Results: All bacterial strains isolated were multidrug resistant. Ethanolic extract of most plants had effective antimicrobial activity against all the isolated multidrug resistant bacteria. Plants, Anthocephalus cadamba (A. cadamba) and Pterocarpus santalinus (P. santalinus) had antibacterial effect on all used bacteria. Water extract of several plants too had effective antimicrobial activity for all bacteria used. Effective in vitro control of MDR strains of Acinetobacter sp., C. freundii, Proteus sp. and P. aeruginosa, the most potential urinary tract infection causing organisms by plant extracts of all major plant used herein is recorded. MDR C. violaceum isolated from skin lesions was found to be resistant to imipenem, piperacillin-tazobactam and amoxyclav and was found sensitive to 13 plant extracts. Conclusion: Effective in vitro control of MDR strains of Acinetobacter sp.,C. freundii, Proteus sp. and P. aeruginosa; enteropathogenic bacteria, E. coli, S. typhi, Klebsiella sp. and V. cholerae were found to be well controlled by all plant extracts used.

    Full Text Available BACKGROUND: Studies on microsporidial infection mostly focus on immunodeficiency or immunosuppressive individuals. Therefore, this cross-sectional study describes the prevalence and risk factors of microsporidiosis among asymptomatic individuals in Malaysia. METHODS/FINDINGS: Four hundred and forty seven stool samples were collected and examined for microsporidia after staining with Gram-chromotrope Kinyoun. Demographic, socioeconomic, environmental, and behavioral information were collected by using a pre-tested questionnaire. Overall, 67 (15% samples were positive for microsporidia. The prevalence of infection was significantly higher among individuals aged more than 15 years compared to those aged <15 years (OR = 1.97, 95% CI = 1.08, 3.62; P = 0.028. Furthermore, logistic regression analysis confirmed that the presence of other family members infected with microsporidia (OR = 8.45; 95% CI = 4.30, 16.62; P<0.001 and being a consumer of raw vegetables (OR = 2.05; 95% CI = 1.15, 3.66; P = 0.016 were the significant risk factors of this infection. CONCLUSIONS: These findings clearly show that exposure to microsporidia is common among Aboriginal population. Further studies using molecular approach on microsporidia isolates from asymptomatic individuals is needed to determine species-specific. The risk factors associated with microsporidiosis will help in identifying more clearly the sources of the infection in the environment that pose a risk for transmission so that preventive strategies can be implemented.

    Full Text Available Objectives: The present study aimed to assess dietary adequacy and quality among Inuvialuit alcohol consumers and non-consumers in the Northwest Territories (NWT, Canada. Study design: Cross-sectional study. Methods: A validated quantitative food frequency questionnaire was administered to individuals (n = 216 of randomly selected households in 3 NWT communities to capture dietary intake and alcohol consumption over a 30-day recall period. The daily energy and nutrient intake, dietary adequacy and the top food sources of energy and selected nutrients were determined by alcohol consumption status. Results: Energy intake was higher among all alcohol consumers regardless of gender. Male alcohol consumers had lower nutrient intake density (per 4,184 kJ of protein, cholesterol and several micronutrients (p ≤ 0.05, and female alcohol consumers had lower intake density of saturated fat (p ≤ 0.01, thiamine, folate and sodium (p ≤ 0.05. Among all men and women, 70–100% had inadequate intakes of dietary fibre, vitamin E and potassium. Non-nutrient-dense foods contributed similar amounts and traditional foods (TF contributed 3% less to energy comparing alcohol consumers to non-consumers. Conclusion: Nutrient inadequacies are prevalent among Aboriginal populations in the Canadian Arctic and may be exacerbated by alcohol consumption due to alcohol's effects on dietary intake, nutrient transport and metabolism. Adult Inuvialuit who consumed alcohol had increased caloric intake and consumed similar amounts of non-nutrient-dense foods and less nutrient-dense TF. Fewer dietary inadequacies were observed among alcohol consumers than non-consumers, which might be due to the increase in overall food intake among alcohol consumers; however, further exploration of volume and pattern of drinking might help explain this result.

    1983-01-01

    Free vibrations of cantilevered circular cylindrical shells having rectangular planforms are studied in this paper by means of the Ritz method. The deep shell theory of Novozhilov and Goldenveizer is used and compared with the usual shallow shell theory for a wide range of shell parameters. A thorough convergence study is presented along with comparisons to previously published finite element solutions and experimental results. Accurately computed frequency parameters and mode shapes for various shell configurations are presented. The present paper appears to be the first comprehensive study presenting rigorous comparisons between the two shell theories in dealing with free vibrations of cantilevered cylindrical shells.

    Full Text Available Background. Because of the epidemic of metabolic syndrome (MS in Australian Aboriginals known for their higher cardiovascular mortality and shorter life expectancy, we analyzed the possible relationship of their MS risks with the current dietary custom. Methods. The subjects were 84 people aged 16–79 years. The health examination was conducted according to the basic protocol of WHO-CARDIAC (Cardiovascular Diseases and Alimentary Comparison Study. Results. The highest prevalence among MS risks was abdominal obesity (over 60%. After controlling for age and sex, the odds of obesity decreased significantly with high level of urinary magnesium/creatinine ratio (Mg/cre (OR, 0.11; 95% CI, 0.02–0.57; P<.05. The significant inverse associations of fat intake with Mg/cre and of fast food intake with urinary taurine/creatinine ratio were revealed. Conclusions. The high prevalence of obesity in the Aboriginal people of this area may partly be due to the reduction of beneficial nutrients intake including Mg and taurine.

    Energy Technology Data Exchange (ETDEWEB)

    Hull, E.W.S.

    1987-01-01

    This paper explores principles of international law for managing nonsovereign marine minerals under conditions of severe chronic global shortage - which herein is defined as existing whenever exploitation consistently exceeds natural rates of renewal restoration. The main data source lies in how man has managed shortage in the past, where the most fertile ground is found in the ways of the natural societies of pre-Neolithic man and contemporary hunter-gatherer bands. The result has a broader compass than the original goal namely the means (a) to restore ecological balance to man's relationship to his resource environment, and (b) to achieve universal fairness of individual access to the global patrimony. These goals may be realized without sudden disruption of the international community of sovereign States or its economic system of laissez-faire capitalism. The means to these ends posit the readoption of aboriginal Ethics to order the adaptive relationship of man to man and of man to Nature, including the revitalization of the original social compact of reciprocal rights and obligations among all individuals. The turn to aboriginal Ethics suggests a series of proposals for managing global shortage implemented by economic incentives and penalties which are compatible with the ways of contemporary international society.

    The mtDNA variation of 411 individuals from 10 aboriginal Siberian populations was analyzed in an effort to delineate the relationships between Siberian and Native American populations. All mtDNAs were characterized by PCR amplification and restriction analysis, and a subset of them was characterized by control region sequencing. The resulting data were then compiled with previous mtDNA data from Native Americans and Asians and were used for phylogenetic analysis and sequence divergence estimations. Aboriginal Siberian populations exhibited mtDNAs from three (A, C, and D) of the four haplogroups observed in Native Americans. However, none of the Siberian populations showed mtDNAs from the fourth haplogroup, group B. The presence of group B deletion haplotypes in East Asian and Native American populations but their absence in Siberians raises the possibility that haplogroup B could represent a migratory event distinct from the one(s) which brought group A, C, and D mtDNAs to the Americas. These findings support the hypothesis that the first humans to move from Siberia to the Americas carried with them a limited number of founding mtDNAs and that the initial migration occurred between 17,000-34,000 years before present. 61 refs., 5 figs., 7 tabs.

    2007-01-01

    A developmental framework for understanding issues of risk, resilience, and wellness among Aboriginal adolescents in Canada and elsewhere is presented. As these constructs are not monolithic, simplistic linear risk models of a specific predictor to a specific outcome are inadequate to conceptually capture the complexities of real-life patterns. Accordingly, the conceptual focus is on ideal constructions of competence within the context of continually ongoing transactions in which the adolescents effect and are effected by the various layers and components of the environment. However, the pragmatics of empirical research necessitate simpler approaches in which outcomes are predicted from specific factors. Nonetheless, in keeping with the notion of the complexity of all individuals, competence and wellness are viewed within the framework of the 'whole child' across domains of academic success, behavioural competence and appropriateness, social adaptation, and emotional health within the context of the specific community. Although Aboriginal communities within Quebec, across Canada, the United States and elsewhere, differ considerably with regard to history, culture, language, and priorities for its youth, this approach allows for the universal application of a framework, for which specifics can be modified in relation to the unique and changing aspects of societies, communities, and the individuals within.

    This paper examines collaborative arrangements between Aboriginal peoples and the forest sector across Canada. Using a broad definition of collaboration, we identified 1378 arrangements in 474 Aboriginal communities in all Canadian provinces and territories, except Nunavut. We categorize these collaborative arrangements into five broad types: treaties and other formal agreements; planning and management activities; influence on decision-making; forest tenures; and economic roles and partnerships. Consistent data was available for only the first three types, which showed that close to 60% of Aboriginal communities use each approach. However, this masks significant differences between provinces. For example, economic roles and partnerships are in place in all New Brunswick communities and 74% of communities in British Columbia, but only 12% of Manitoban communities. The proportion of communities that have been involved in participatory processes in forest decision-making (such as advisory committees and consultation processes) is particularly high in Quebec with 88% of communities, but only 32% of communities hold forest tenures. We also find that three-quarters of all communities choose to engage in two or more approaches, despite the demands that this can place upon the time and energy of community members. We finally consider how policy environments in different jurisdictions affect the frequency of certain types of collaboration. This empirical study, and the typology that it demonstrates, can inform policy development for Aboriginal involvement in Canadian forestry and help guide future research into broader issues of collaborative governance of natural resources.

    This volume focuses on the relevant general theory and presents some first applications, namely those based on classical shell theory. After a brief introduction, during which the history and state-of-the-art are discussed, the first chapter presents the mechanics of anisotropic heterogeneous shells, covering all relevant assumptions and the basic relations of 3D elasticity, classical and refined shell models. The second chapter examines the numerical techniques that are used, namely discrete orthogonalization, spline-collocation and Fourier series, while the third highlights applications based on classical theory, in particular, the stress-strain state of shallow shells, non-circular shells, shells of revolution, and free vibrations of conical shells. The book concludes with a summary and an outlook bridging the gap to the second volume.

    Thin shells are found in nature at scales ranging from viruses to hens\\' eggs; the stiffness of such shells is essential for their function. We present the results of numerical simulations and theoretical analyses for the indentation of ellipsoidal and cylindrical elastic shells, considering both pressurized and unpressurized shells. We provide a theoretical foundation for the experimental findings of Lazarus etal. [following paper, Phys. Rev. Lett. 109, 144301 (2012)PRLTAO0031-9007] and for previous work inferring the turgor pressure of bacteria from measurements of their indentation stiffness; we also identify a new regime at large indentation. We show that the indentation stiffness of convex shells is dominated by either the mean or Gaussian curvature of the shell depending on the pressurization and indentation depth. Our results reveal how geometry rules the rigidity of shells. © 2012 American Physical Society.

    A turbine blade with a spar and shell construction in which the spar and the shell are both secured within two platform halves. The spar and the shell each include outward extending ledges on the bottom ends that fit within grooves formed on the inner sides of the platform halves to secure the spar and the shell against radial movement when the two platform halves are joined. The shell is also secured to the spar by hooks extending from the shell that slide into grooves formed on the outer surface of the spar. The hooks form a serpentine flow cooling passage between the shell and the spar. The spar includes cooling holes on the lower end in the leading edge region to discharge cooling air supplied through the platform root and into the leading edge cooling channel.

  2. Setting and meeting priorities in Indigenous health research in Australia and its application in the Cooperative Research Centre for Aboriginal Health

    Anderson Ian PS

    2009-11-01

    Full Text Available Abstract Priority setting is about making decisions. Key issues faced during priority setting processes include identifying who makes these decisions, who sets the criteria, and who benefits. The paper reviews the literature and history around priority setting in research, particularly in Aboriginal health research. We explore these issues through a case study of the Cooperative Research Centre for Aboriginal Health (CRCAH's experience in setting and meeting priorities. Historically, researchers have made decisions about what research gets done. Pressures of growing competition for research funds and an increased public interest in research have led to demands that appropriate consultation with stakeholders is conducted and that research is of benefit to the wider society. Within Australian Aboriginal communities, these demands extend to Aboriginal control of research to ensure that Aboriginal priorities are met. In response to these demands, research priorities are usually agreed in consultation with stakeholders at an institutional level and researchers are asked to develop relevant proposals at a project level. The CRCAH's experience in funding rounds was that scientific merit was given more weight than stakeholders' priorities and did not necessarily result in research that met these priorities. After reviewing these processes in 2004, the CRCAH identified a new facilitated development approach. In this revised approach, the setting of institutional priorities is integrated with the development of projects in a way that ensures the research reflects stakeholder priorities. This process puts emphasis on identifying projects that reflect priorities prior to developing the quality of the research, rather than assessing the relevance to priorities and quality concurrently. Part of the CRCAH approach is the employment of Program Managers who ensure that stakeholder priorities are met in the development of research projects. This has enabled

    Future Integrated Coal Gasification Combined Cycle (ICGCC) power plants will have superior environmental performance and efficiency. The Shell Coal Gasification Process (SCGP) is a clean coal technology, which can convert a wide range of coals into clean syngas for high efficiency electricity generation in an ICGCC plant. SCGP flexibility has been demonstrated for high-rank bituminous coals to low rank lignites and petroleum coke, and the process is well suited for combined cycle power generation, resulting in efficiencies of 42 to 46% (LHV), depending on choice of coal and gas turbine efficiency. In the Netherlands, a 250 MWe coal gasification combined cycle plant based on Shell technology has been built by Demkolec, a development partnership of the Dutch Electricity Generating Board (N.V. Sep). The construction of the unit was completed end 1993 and is now followed by start-up and a 3 year demonstration period, after that the plant will be part of the Dutch electricity generating system.

  4. Shell trips over its reserves

    International Nuclear Information System (INIS)

    Some mistakes in the evaluation of the proven reserves of Royal Dutch Shell group, the second world petroleum leader, will oblige the other oil and gas companies to be more transparent and vigilant in the future. The proven reserves ('P90' in petroleum professionals' language) are the most important indicators of the mining patrimony of companies. These strategic data are reported each year in the annual reports of the companies and are examined by the security exchange commission. The evaluation of reserves is perfectly codified by the US energy policy and conservation act and its accountable translation using the FAS 69 standard allows to establish long-term cash-flow forecasts. The revision announced by Shell on January 9 leads to a 20% reduction of its proven reserves. Short paper. (J.S.)

    Superfluid helium consists of two inter-penetrating fluids, a viscous normal fluid and an inviscid superfluid, coupled by a mutual friction. We develop a two-fluid shell model to study superfluid turbulence and investigate the energy spectra and the balance of fluxes between the two fluids in a steady state. At sufficiently low temperatures a 'bottle-neck' develops at high wavenumbers suggesting the need for a further dissipative effect, such as the Kelvin wave cascade.

    The shape and structure of the shells of molluscs has attracted considerable attention. One aspect of interest is the comparatively high resistance to fracture of these shells. It is known that they are composite structures of aragonite, other calcereous materials, and up to 5% by volume of protein 'glue'. A large component of their toughening derives from crack tip blunting, deflection and closure, concepts well-known from the field of fracture mechanics. However, the possibility that they might also derive a measure of toughening from a residual stress distribution has been generally overlooked, although Illert first raised this over a decade ago. The optimum situation would be when the inner surface of the shell is maintained in a state of tensile stress, while the outer layers are in the necessarily counter-balancing compressive state. We have examined this hypothesis using a combination of neutron diffraction and scanning electron microscopy and find that it is certainly feasible. However, a definitive proof will require a diffraction study at higher resolution.

  10. Shell evolutions and nuclear forces

    International Nuclear Information System (INIS)

    Combining all experimental discoveries, some remarkable and general shell evolutions can be observed in the chart of nuclides. In the present contribution, the striking analogy between the behavior of the harmonic oscillator gaps N=8, 20 and 40 from the valley of stability to more neutron-rich regions is presented in section 2. The onset of deformation through intruder configurations at N=20 is depicted in section 3 using two recent experimental studies on the 34Si and 32Mg isotones. Section 4 proposes to study the evolution of the neutron single particle energies of the neutron d3/2, f7/2 and p3/2 orbitals between which the N=20 and N=28 gaps are formed. The underlying nuclear forces leading to the disappearance of the N=20 shell gap and the swapping between the f7/2 and p3/2 orbit is described. Section 5 shows that a hierarchy in the nuclear forces is responsible for these drastic shell evolutions. A generalization of this mechanism to other regions of the chart of nuclides (around 60Ca, below 78Ni and below 132Sn where the r-process nucleosynthesis occurs) is also proposed

  11. Atomic inner-shell transitions

    Crasemann, B.; Chen, M. H.; Mark, H.

    1984-01-01

    Atomic inner-shell processes have quite different characteristics, in several important aspects, from processes in the optical regime. Energies are large, e.g., the 1s binding energy reaches 100 keV at Z = 87; relativistic and quantum-electrodynamic effects therefore are strong. Radiationless transitions vastly dominate over photon emission in most cases. Isolated inner-shell vacancies have pronounced single-particle character, with correlations generally contributing only approximately 1 eV to the 1s and 2p binding energies; the structure of such systems is thus well tractable by independent-particle self-consistent-field atomic models. For systems containing multiple deep inner-shell vacancies, or for highly stripped ions, the importance of relativistic intermediate coupling and configuration interaction becomes pronounced. Cancellation of the Coulomb interaction can lead to strong manifestations of the Breit interaction in such phenomena as multiplet splitting and hypersatellite X-ray shifts. Unique opportunities arise for the test of theory.

  12. Asymptotic safety goes on shell

    Benedetti, Dario

    2011-01-01

    It is well known in quantum field theory that the off-shell effective action depends on the gauge choice and field parametrization used in calculating it. Nevertheless, the typical scheme in which the scenario of asymptotically safe gravity is investigated is an off-shell version of the functional renormalization group equation. Working with the Einstein-Hilbert truncation as a test bed, we develop a new scheme for the analysis of asymptotically safe gravity in which the on-shell part of the effective action is singled out and we show that the beta function for the essential coupling has no explicit gauge-dependence. In order to reach our goal, we introduce several technical novelties, including a different decomposition of the metric fluctuations, a new implementation of the ghost sector, and a new cut-off scheme. We find a non-trivial fixed point, with a value of the cosmological constant which is independent of the gauge-fixing parameters.

    2014-10-28

    Colloidal polymer particles are an important class of materials finding use in both everyday and basic research applications. Tailoring their composition, shape, and functionality is of key importance. In this article, we describe a new class of shape-tunable core-shell microparticles. They are composed of a cross-linked polystyrene (PS) core and a poly(methyl methacrylate) (PMMA) shell of varying thickness. In the first step, we prepared highly cross-linked PS cores, which are subsequently transferred into a nonpolar dispersant. They serve as the seed dispersion for a nonaqueous dispersion polymerization to generate the PMMA shell. The shape of the particles can subsequently be manipulated. After the shell growth stage, the spherical PS/PMMA core-shell colloids exhibit an uneven and wrinkled surface. An additional tempering procedure allows for smoothing the surface of the core-shell colloids. This results in polymer core-shell particles with a perfectly spherical shape. In addition to this thermal smoothing of the PMMA shell, we generated a selection of shape-anisotropic core-shell particles using a thermomechanical stretching procedure. Because of the unique constitution, we can selectively interrogate molecular vibrations in the PS core or the PMMA shell of the colloids using nonlinear optical microscopy techniques. This is of great interest because no photobleaching occurs, such that the particles can be tracked in real space over long times.

METHODS: We collected 1,500 nasopharyngeal specimens from Aboriginal people living in varied regions of WA from August 2008 until June 2011. Specimens were cultured on selective media. Pneumococcal isolates were serotyped by the quellung reaction. RESULTS: Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were carried by 71.9%, 63.2% and 63.3% respectively of children <5 years of age, and 34.6%, 22.4% and 27.2% of people ≥5 years. Of 43 pneumococcal serotypes identified, the most common were 19A, 16F and 6C in children <5 years, and 15B, 34 and 22F in older people. 7vPCV serotypes accounted for 14.5% of all serotypeable isolates, 13vPCV for 32.4% and 23vPPV for 49.9%, with little variation across all age groups. Serotypes 1 and 12F were rarely identified, despite causing recent IPD outbreaks in WA. Complete penicillin resistance (MIC ≥2µg/ml was found in 1.6% of serotype 19A (5.2%, 19F (4.9% and 16F (3.2% isolates and reduced penicillin susceptibility (MIC ≥0.125µg/ml in 24.9% of isolates, particularly 19F (92.7%, 19A (41.3%, 16F (29.0%. Multi-resistance to cotrimoxazole, tetracycline and erythromycin was found in 83.0% of 23F isolates. Among non-serotypeable isolates 76.0% had reduced susceptibility and 4.0% showed complete resistance to penicillin. CONCLUSIONS: Ten years after introduction of 7vPCV for Aboriginal Australian children, 7vPCV serotypes account for a small proportion of carried

    Full Text Available Abstract Background Australian federal and jurisdictional governments are implementing ambitious policy initiatives intended to improve health care access and outcomes for Aboriginal and Torres Strait Islander people. In this qualitative study we explored Aboriginal Medical Service (AMS staff views on factors needed to improve chronic care systems and assessed their relevance to the new policy environment. Methods Two theories informed the study: (1 ‘candidacy’, which explores “the ways in which people’s eligibility for care is jointly negotiated between individuals and health services”; and (2 kanyini or ‘holding’, a Central Australian philosophy which describes the principle and obligations of nurturing and protecting others. A structured health systems assessment, locally adapted from Chronic Care Model domains, was administered via group interviews with 37 health staff in six AMSs and one government Indigenous-led health service. Data were thematically analysed. Results Staff emphasised AMS health care was different to private general practices. Consistent with kanyini, community governance and leadership, community representation among staff, and commitment to community development were important organisational features to retain and nurture both staff and patients. This was undermined, however, by constant fear of government funding for AMSs being withheld. Staff resourcing, information systems and high-level leadership were perceived to be key drivers of health care quality. On-site specialist services, managed by AMS staff, were considered an enabling strategy to increase specialist access. Candidacy theory suggests the above factors influence whether a service is ‘tractable’ and ‘navigable’ to its users. Staff also described entrenched patient discrimination in hospitals and the need to expend considerable effort to reinstate care. This suggests that Aboriginal and Torres Strait Islander people are still

    Full Text Available Abstract Background Middle ear disease (otitis media is common and frequently severe in Australian Aboriginal children. There have not been any recent large-scale surveys using clear definitions and a standardised middle ear assessment. The aim of the study was to determine the prevalence of middle ear disease (otitis media in a high-risk population of young Aboriginal children from remote communities in Northern and Central Australia. Methods 709 Aboriginal children aged 6–30 months living in 29 communities from 4 health regions participated in the study between May and November 2001. Otitis media (OM and perforation of the tympanic membrane (TM were diagnosed by tympanometry, pneumatic otoscopy, and video-otoscopy. We used otoscopic criteria (bulging TM or recent perforation to diagnose acute otitis media. Results 914 children were eligible to participate in the study and 709 were assessed (78%. Otitis media affected nearly all children (91%, 95%CI 88, 94. Overall prevalence estimates adjusted for clustering by community were: 10% (95%CI 8, 12 for unilateral otitis media with effusion (OME; 31% (95%CI 27, 34 for bilateral OME; 26% (95%CI 23, 30 for acute otitis media without perforation (AOM/woP; 7% (95%CI 4, 9 for AOM with perforation (AOM/wiP; 2% (95%CI 1, 3 for dry perforation; and 15% (95%CI 11, 19 for chronic suppurative otitis media (CSOM. The perforation prevalence ranged from 0–60% between communities and from 19–33% between regions. Perforations of the tympanic membrane affected 40% of children in their first 18 months of life. These were not always persistent. Conclusion Overall, 1 in every 2 children examined had otoscopic signs consistent with suppurative ear disease and 1 in 4 children had a perforated tympanic membrane. Some of the children with intact tympanic membranes had experienced a perforation that healed before the survey. In this high-risk population, high rates of tympanic perforation were associated with high

    2007-07-01

    In this paper, the creeping flow of an incompressible viscous liquid past a porous approximate spherical shell is considered. The flow in the free fluid region outside the shell and in the cavity region of the shell is governed by the Navier Stokes equation. The flow within the porous annulus region of the shell is governed by Darcy’s Law. The boundary conditions used at the interface are continuity of the normal velocity, continuity of the pressure and Beavers and Joseph slip condition. An exact solution for the problem is obtained. An expression for the drag on the porous approximate spherical shell is obtained. The drag experienced by the shell is evaluated numerically for several values of the parameters governing the flow.

    2013-03-01

    Full Text Available Mussels are commonly used in cooking around the world. The mussel shell breaks more easily than other shells, and the edge of the broken mussel shell is sharp. Impaction can ultimately cause erosion, perforation and fistula. Aside from these complications, the pain can be very intense. Therefore, it is essential to verify and remove the shell as soon as possible. In this report we describe the process of diagnosing and treating mussel shell impaction in the esophagus. Physicians can overlook this unusual foreign body impaction due to lack of experience. When physicians encounter a patient with severe chest pain after a meal with mussels, mussel shell impaction should be considered when diagnosing and treating the patient.

    This thesis presents research results on the deformation of elastic shells, especially concerning buckling and wrinkling instabilities. The theoretical description of such deformations is used to develop methods of shape analysis, which serve to infer material properties from simple experimental observations of deformed shells. When an initially spherical shell is deflated, two successive instabilities can typically be observed. In a first buckling transition, an axisymmetric dimple appears....

    In this paper we analyze the laws of growth that control planktic foraminiferal shell morpholoy. We assume that isometry is the key towards the understanding of their ontogeny. Hence, our "null hypothesis" is that these organisms construct isometric shells. To test this hypothesis, geometric models of their shells have been generated with a personal computer. It is demonstrated that early chambers in log-spirally coiled structures can not follow a strict isometric arrangement. In the real wor...

    Full Text Available EnglishIn 2005, Statistics Canada published new projections of the Aboriginal populations (NorthAmerican Indians, Métis, and Inuit in Canada, the provinces and territories from 2001 to2017.

    Full Text Available Abstract Background Understanding people's social lived experiences of chronic illness is fundamental to improving health service delivery and health outcomes, particularly in relation to self-management activity. In explorations of social lived experiences this paper uncovers the ways in which Aboriginal and Torres Strait Islander people with chronic illness experience informal unsolicited support from peers and family members. Methods Nineteen Aboriginal and Torres Islander participants were interviewed in the Serious and Continuing Illness Policy and Practice Study (SCIPPS. Participants were people with Type 2 diabetes (N = 17, chronic obstructive pulmonary disease (N = 3 and/or chronic heart failure (N = 11 and family carers (N = 3. Participants were asked to describe their experience of having or caring for someone with chronic illness. Content and thematic analysis of in-depth semi-structured interviews was undertaken, assisted by QSR Nvivo8 software. Results Participants reported receiving several forms of unsolicited support, including encouragement, practical suggestions for managing, nagging, growling, and surveillance. Additionally, participants had engaged in 'yarning', creating a 'yarn' space, the function of which was distinguished as another important form of unsolicited support. The implications of recognising these various support forms are discussed in relation to responses to unsolicited support as well as the needs of family carers in providing effective informal support. Conclusions Certain locations of responsibility are anxiety producing. Family carers must be supported in appropriate education so that they can provide both solicited and unsolicited support in effective ways. Such educational support would have the added benefit of helping to reduce carer anxieties about caring roles and responsibilities. Mainstream health services would benefit from fostering environments that encourage informal interactions that

    2011-08-01

    Full Text Available This paper is based on the 11th annual Doireann MacDermott public lecture presented at the Universitat de Barcelona in November, 2010. It is a critique of discourses and representations in Australian society, and indeed, embedded in all western societies (and many non-western societies I suspect which support and reinforce artificial binary oppositions which make up social structures and institutions. Binary oppositions reinforce oppositional power dynamics, making one term positive and the other negative, not recognizing categories in-between. Linguistically, for example, the terms ‘Indigenous’ and ‘non-Indigenous’ articulate a false dichotomy between people who, empirically, are not two discrete groups, but rather, multiple groups within each category which interact within and between groups in complex and fluid engagements. The discourses and representations I discuss in this paper articulate imaginary binary oppositions out of social processes and identities which are, in fact, very similar. However, because these discourses and representations are constructed by different social groups with unequal power relationships they are treated as opposites, one with a higher value than the other. In this paper I am primarily concerned with history and myth, and in two related ‘stories’, the Lachlan Macquarie story, classified as history because it is primarily written and ‘belongs’ to the dominant Australian society, and the Maria Locke story, classified as myth because it is primarily oral, and explains the emergence and characteristics of a group of Aboriginal people who claim traditional Aboriginal ownership of a large part of what is today called Sydney.

    Objective To describe the attitudes and beliefs of health professionals working in Aboriginal Community Controlled Health Services (ACCHS) towards the access, usage and potential value of routinely obtained clinical and research data. Design, setting and participants Face-to-face, semistructured interviews were conducted with 35 health professionals from 2 urban and 1 regional ACCHS in New South Wales. The interviews were transcribed and themes were identified using an adapted grounded theory approach. Results Six major themes were identified: occupational engagement (day-to-day relevance, contingent on professional capacity, emphasising clinical relevance), trust and assurance (protecting ownership, confidence in narratives, valuing local sources), motivation and empowerment (engaging the community, influencing morale, reassuring and encouraging clients), building research capacity (using cultural knowledge, promoting research aptitude, prioritising specific data), optimising service provision (necessity for sustainable services, guiding and improving services, supporting best practice), and enhancing usability (ensuring ease of comprehension, improving efficiency of data management, valuing accuracy and accessibility). Conclusions Participants were willing to learn data handling procedures that could further enhance health service delivery and enable more ACCHS-led research, but busy workloads restrict these opportunities. Staff held concerns regarding the translation of research data into beneficial services, and believed that the outcome and purpose of data collection could be communicated more clearly. Promoting research partnerships, ensuring greater awareness of positive health data and the purposes of data collection, and communicating data in a user-friendly format are likely to encourage greater data use, build research capacity and improve health services within the Aboriginal community.

    2011-10-01

    This paper examines responses to racism and the pathways through which racism can affect health and wellbeing for Aboriginal people living in an urban environment. Face-to-face interviews were conducted in 2006/07 with 153 Aboriginal people living in Adelaide, Australia. Participants were asked about their experience of, and responses to, racism, and the impact of these experiences on their health. Racism was regularly experienced by 93% of participants. Almost two thirds of people felt that racism affected their health. Using a thematic analysis with a particular focus on how agency and structure interacted, a number of key reactions and responses to racism were identified. These included: emotional and physiological reactions; and responses such as gaining support from social networks; confronting the person/situation; ignoring it; avoiding situations where they might experience racism; 'minimising' the significance or severity of racism or questioning whether incidents were racist; and consuming alcohol, tobacco and other drugs. A further theme was a conscious decision to not 'allow' racism to affect health. Our study found that most people used more than one of these coping strategies, and that strategies were selected with an awareness of positive and negative health impacts. While individuals demonstrated substantial agency in their responses, there were clear structural constraints on how they reacted and responded. We found that not only was racism potentially detrimental to health, but so too were some responses. However, while some strategies appeared 'healthier' than others, most strategies entailed costs and benefits, and these depended on the meanings of responses for individuals. This paper concludes that initiatives to promote health-protective responses to racism need to consider structural constraints and the overarching goal of reducing systemic racism. PMID:21835522

    Full Text Available Abstract Background It is unclear why some children with acute otitis media (AOM have poor outcomes. Our aim was to describe the clinical course of AOM and the associated bacterial nasopharyngeal colonisation in a high-risk population of Australian Aboriginal children. Methods We examined Aboriginal children younger than eight years who had a clinical diagnosis of AOM. Pneumatic otoscopy and video-otoscopy of the tympanic membrane (TM and tympanometry was done every weekday if possible. We followed children for either two weeks (AOM without perforation, or three weeks (AOM with perforation, or for longer periods if the infection persisted. Nasopharyngeal swabs were taken at study entry and then weekly. Results We enrolled 31 children and conducted a total of 219 assessments. Most children had bulging of the TM or recent middle ear discharge at diagnosis. Persistent signs of suppurative OM (without ear pain were present in most children 7 days (23/30, 77%, and 14 days (20/26, 77% later. Episodes of AOM did not usually have a sudden onset or short duration. Six of the 14 children with fresh discharge in their ear canal had an intact or functionally intact TM. Perforation size generally remained very small (Streptococcus pneumoniae (82%, Haemophilus influenzae (71%, and Moraxella catarrhalis (95%; 63% of swabs cultured all three pathogens. Conclusion In this high-risk population, AOM was generally painless and persistent. These infections were associated with persistent bacterial colonisation of the nasopharynx and any benefits of antibiotics were modest at best. Systematic follow up with careful examination and review of treatment are required and clinical resolution cannot be assumed.

    An optimized methodology to design a more robust torpedo shell is proposed. The method has taken into account reliability requirements and controllable and uncontrollable factors such as geometry, load, material properties, manufacturing processes, installation, etc. as well as human and environmental factors. The result is a more realistic shell design. Our reliability optimization design model was developed based on sensitivity analysis. Details of the design model are given in this paper. An example of a torpedo shell design based on this model is given and demonstrates that the method produces designs that are more effective and reliable than traditional torpedo shell designs. This method can be used for other torpedo system designs.

  14. Carbon isotopes in mollusk shell carbonates

    McConnaughey, Ted A.; Gillikin, David Paul

    2008-10-01

    Mollusk shells contain many isotopic clues about calcification physiology and environmental conditions at the time of shell formation. In this review, we use both published and unpublished data to discuss carbon isotopes in both bivalve and gastropod shell carbonates. Land snails construct their shells mainly from respired CO2, and shell δ13C reflects the local mix of C3 and C4 plants consumed. Shell δ13C is typically >10‰ heavier than diet, probably because respiratory gas exchange discards CO2, and retains the isotopically heavier HCO3 -. Respired CO2 contributes less to the shells of aquatic mollusks, because CO2/O2 ratios are usually higher in water than in air, leading to more replacement of respired CO2 by environmental CO2. Fluid exchange with the environment also brings additional dissolved inorganic carbon (DIC) into the calcification site. Shell δ13C is typically a few ‰ lower than ambient DIC, and often decreases with age. Shell δ13C retains clues about processes such as ecosystem metabolism and estuarine mixing. Ca2+ ATPase-based models of calcification physiology developed for corals and algae likely apply to mollusks, too, but lower pH and carbonic anhydrase at the calcification site probably suppress kinetic isotope effects. Carbon isotopes in biogenic carbonates are clearly complex, but cautious interpretation can provide a wealth of information, especially after vital effects are better understood.

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The resonance sound radiation from submerged infinite elastic cylindrical shell, excited by internal harmonic line force, is investigated. The shell radiation power is presented in terms of resonant modal radiation derived from resonance radiation theory (RRT). The resonance radiation formulae are derived from classical Rayleigh normal mode solution, which are useful for understanding the mechanism of sound radiation from submerged shells. As an example, numerical calculation of a thin steel cylindrical shell is done by using these two methods. It seems that the results of RRT solutions are in good agreement with that of Rayleigh normal mode solutions.

    Full Text Available In this paper an optimization problem for a cylindrical shell is discussed. The aim is to look for an optimal thickness of a shell to minimize the deformation under an applied external force. As a side condition, the volume of the shell has to stay constant during the optimization process. The deflection is calculated using an approach from shell theory. The resulting control-to-state operator is investigated analytically and a corresponding optimal control problem is formulated. Moreover, necessary conditions for an optimal solution are stated and numerical solutions are presented for different examples.

    2006-01-01

    The internal control problem is considered, based on the linear displacement equations of shallow shell. It is shown, with some checkable geometric conditions on control region, that the undergoing shallow shell is exactly controllable by using Hilbert uniqueness method (HUM), piecewise multiplier method and Riemannian geometry method. Then some examples are given to show the assumed geometric conditions.
