    Oysters (Crassostrea virginica) were an important food resource for native peoples of the northern Gulf of Mexico, who deposited waste shells in middens. Nitrogen (N) stable isotopes (δ15N) in bivalve shells have been used as modern proxies for estuarine N sources because they approximate δ15N in suspended particulate matter. We tested the use of midden shell δ15N as a proxy for ancient estuarine N sources. We hypothesized that isotopic signatures in ancient shells from coastal Mississippi would differ from modern shells due to increased anthropogenic N sources, such as wastewater, through time. We decalcified shells using an acidification technique previously developed for modern bivalves, but modified to determine δ15N, δ13C, %N, and % organic C of these low-N, high-C specimens. The modified method resulted in the greatest percentage of usable data from midden shells. Our results showed that oyster shell δ15N did not significantly differ between ancient (500-2100 years old) and modern oysters from the same locations where the sites had undergone relatively little land-use change. δ15N values in modern shells, however, were positively correlated with water column nitrate concentrations associated with urbanization. When N content and total shell mass were combined, we estimated that middens sequestered 410-39,000 kg of relic N, buried at a rate of up to 5 kg N m-2 yr-1. This study provides a relatively simple technique to assess baseline conditions in ecosystems over long time scales by demonstrating that midden shells can be an indicator of pre-historic N source to estuaries and are a potentially significant but previously uncharacterized estuarine N sink.

    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. From Shell Midden to Midden-Mound: The Geoarchaeology of Mound Key, an Anthropogenic Island in Southwest Florida, USA.

    Victor D Thompson

    Full Text Available Mound Key was once the capital of the Calusa Kingdom, a large Pre-Hispanic polity that controlled much of southern Florida. Mound Key, like other archaeological sites along the southwest Gulf Coast, is a large expanse of shell and other anthropogenic sediments. The challenges that these sites pose are largely due to the size and areal extent of the deposits, some of which begin up to a meter below and exceed nine meters above modern sea levels. Additionally, the complex depositional sequences at these sites present difficulties in determining their chronology. Here, we examine the development of Mound Key as an anthropogenic island through systematic coring of the deposits, excavations, and intensive radiocarbon dating. The resulting data, which include the reversals of radiocarbon dates from cores and dates from mound-top features, lend insight into the temporality of site formation. We use these insights to discuss the nature and scale of human activities that worked to form this large island in the context of its dynamic, environmental setting. We present the case that deposits within Mound Key's central area accumulated through complex processes that represent a diversity of human action including midden accumulation and the redeposition of older sediments as mound fill.

    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.

    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.

    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

    Rodent (Abrocoma, Lagidium, Phyllotis) middens collected from 2350 to 2750 m elevation near Arequipa, Peru (16??S), provide an ???9600-yr vegetation history of the northern Atacama Desert, based on identification of >50 species of plant macrofossils. These midden floras show considerable stability throughout the Holocene, with slightly more mesophytic plant assemblages in the middle Holocene. Unlike the southwestern United States, rodent middens of mid-Holocene age are common. In the Arequipa area, the midden record does not reflect any effects of a mid-Holocene mega drought proposed from the extreme lowstand (100 m below modern levels, >6000 to 3500 yr B.P.) of Lake Titicaca, only 200 km east of Arequipa. This is perhaps not surprising, given other evidence for wetter summers on the Pacific slope of the Andes during the middle Holocene as well as the poor correlation of summer rainfall among modern weather stations in the central AndesAtacama Desert. The apparent difference in paleoclimatic reconstructions suggests that it is premature to relate changes observed during the Holocene to changes in El Nin??o Southern Oscillation modes. ?? 2001 University of Washington.

    Full Text Available Since 2008 the NSW Government has been investigating the concept of ‘wellbeing’ as it relates to Aboriginal communities. Adopting a focus on wellbeing has meant delving into questions about what makes communities strong, and what factors are unique to creating strong Aboriginal communities, as well as considering the government’s role (if any in supporting Aboriginal community wellbeing. This paper seeks to convey the essence of the journey into wellbeing to date. It details the positions and assumptions that this work started with, and analyses why this has shifted over time. It examines what worked and was feasible, and what didn’t. In particular, the paper overviews the creation of the Strengthening Aboriginal Community Wellbeing Framework (the policy context, and the development of a resource in the form of a user friendly software program for communities wishing to holistically assess their wellbeing – the ‘toolkit’ (the practical outcome of the work to date.

    Identification of >40 taxa of plant macrofossils in 14 rodent (Abrocoma) middens collected from 2800 to 3590 m elevation at the latitude of Arica, Chile (18°S) provide snapshots of vegetation in the northernmost Atacama Desert over the past 3000 years. Midden floras show considerable stability throughout the late Holocene, which may be due in part to the broad elevational ranges of many perennial species and midden insensitivity to changes in plant community structure. The greatest variability is found in annuals in the Prepuna, a climatically sensitive zone. This variability, however might also arise from the brevity of midden depositional episodes. As the first midden record from the Arica-Parinacota Region (Chile's northernmost administrative region), this study demonstrates the potential for future midden research in this area.

  19. Tuberculosis in Aboriginal Canadians

    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.

    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.

  5. Red squirrel middens influence abundance but not diversity of other vertebrates.

    Directory of Open Access Journals (Sweden)

    Erin E Posthumus

    Full Text Available Some animals modify the environment in ways that can influence the resources available to other species. Because red squirrels (Tamiasciurus hudsonicus create large piles of conifer-cone debris (middens in which they store cones, squirrels concentrate resources that might affect biodiversity locally. To determine whether other animals are attracted to midden sites beyond their affinity for the same resources that attract red squirrels, we assessed associations between middens, mammals, and birds at population and community levels. We surveyed 75 middens where residency rates of red squirrels varied during the previous five years; sampling along this residency gradient permitted us to evaluate the influence of resources at middens beyond the influence of a resident squirrel. At each location, we quantified vegetation, landscape structure, abundance of conifer cones, and midden structure, and used capture-recapture, distance sampling, and remote cameras to quantify presence, abundance, and species richness of mammals and birds. Red squirrels and the resources they concentrated at middens influenced mammals and birds at the population scale and to a lesser extent at the community scale. At middens with higher residency rates of red squirrels, richness of medium and large mammals increased markedly and species richness of birds increased slightly. After accounting for local forest characteristics, however, only species richness of medium-to-large mammals was associated with a red squirrel being resident during surveys. In areas where red squirrels were resident during surveys or in areas with greater amounts of resources concentrated by red squirrels, abundances of two of four small mammal species and two of four bird species increased. We conclude that the presence of this ecosystem modifier and the resources it concentrates influence abundance of some mammals and birds, which may have implications for maintaining biodiversity across the wide

  6. 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.

    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.

  10. 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.

  11. 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.

  14. 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

    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.

  16. The Astronomy of Aboriginal Australia

    Norris, Ray P

    2009-01-01

    The traditional cultures of Aboriginal Australians include a significant astronomical component, which is usually reported in terms of songs or stories associated with stars and constellations. Here we argue that the astronomical components extend further, and include a search for meaning in the sky, beyond simply mirroring the earth-bound understanding. In particular, we have found that traditional Aboriginal cultures include a deep understanding of the motion of objects in the sky, and that this knowledge was used for practical purposes such as constructing calendars. We also present evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, and paid careful attention to unexpected phenomena such as eclipses and meteorite impacts.

    Full Text Available This paper addresses the common assumption that Aboriginal art has been absent from Australian art histories and demonstrates how this is not so. It criticises the notion that art history should be represented by specialised art-history books and argues for the important of art museum displays as texts. It also examines the ways in which Aboriginal art has been examined in literature devoted to Australian history and anthropology. It foregrounds the idea that arts history is not necessarily best represented by official art historical texts.

  3. 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.

  4. In Search of the Aboriginal Self

    Directory of Open Access Journals (Sweden)

    Lloyd Hawkeye Robertson

    2014-05-01

    Full Text Available Notions of aboriginal cultural reclamation and healing presuppose the existence of distinctly aboriginal selves that were damaged or lost in a process of colonization and that those selves can be “restored” in some meaningful way. Such aboriginal healing has been done without a detailed examination of the selves of individuals to be assisted in this manner. This article examines the selves of four contemporary individuals with varying relationships to the concept of aboriginality using a method of mapping the self with elemental units of culture called “memes.” It is suggested that a spectrum of healthy selves is possible for people who either identify with aboriginality culturally or satisfy a racial definition of the concept. The co-evolution of the self and culture is discussed along with the utility of various definitions of what it means to be aboriginal in a North American context.

  8. 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.

    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 these 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 for 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.

    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.

    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.

    2016-10-01

    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.

  16. A genomic history of Aboriginal Australia

    2016-09-20

    The population history of Aboriginal Australians remains largely uncharacterized. Here we generate high-coverage genomes for 83 Aboriginal Australians (speakers of Pama-Nyungan languages) and 25 Papuans from the New Guinea Highlands. We find that Papuan and Aboriginal Australian ancestors diversified 25-40 thousand years ago (kya), suggesting pre-Holocene population structure in the ancient continent of Sahul (Australia, New Guinea and Tasmania). However, all of the studied Aboriginal Australians descend from a single founding population that differentiated ∼10-32 kya. We infer a population expansion in northeast Australia during the Holocene epoch (past 10,000 years) associated with limited gene flow from this region to the rest of Australia, consistent with the spread of the Pama-Nyungan languages. We estimate that Aboriginal Australians and Papuans diverged from Eurasians 51-72 kya, following a single out-of-Africa dispersal, and subsequently admixed with archaic populations. Finally, we report evidence of selection in Aboriginal Australians potentially associated with living in the desert. © 2016 Macmillan Publishers Limited, part of Springer Nature. All rights reserved

    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.

    Williams, Corinne J; Masterson, Julie J

    2010-12-01

    This study investigated the phonological awareness and early spelling skills of 10 Australian Aboriginal and 10 non-Aboriginal children in their first year of schooling at urban schools. Phonological awareness was assessed using a standardized test (the Queensland University Inventory of Literacy), and children completed a standard spelling task that required them to generate spelling attempts in response to 12 line drawings of familiar animals. Spelling was analysed using the Spelling Scoring Sensitivity procedure. All children performed within the normal range for scores on the QUIL. However, as a group, Aboriginal children performed more poorly than their non-Aboriginal peers. Statistically significant differences were found on the subtests non-word spelling, non-word reading, and phoneme segmentation. Both formal scoring and informal observations were used to examine the spelling skills of participants. Possible explanations of the differences between groups are discussed in terms of health and cultural factors, and implications for the education of Aboriginal children are suggested.

  1. Late quaternary arthropod remains from Sonoran Desert packrat middens, southwestern Arizona and northwestern Sonora

    Science.gov (United States)

    Hall, W. Eugene; Van Devender, Thomas R.; Olson, Carl A.

    1988-05-01

    A total of 50 arthropod taxa were identified from 41 fossil packrat ( Neotoma sp.) middens from 160 to 625 m elevation in three study areas in the Lower Colorado River Valley subdivision of the Sonoran Desert. Radiocarbon dates associated with the middens range from >43,200 to 610 yr B.P. The fauna in the Tinajas Altas Mountains, southwestern Arizona, was relatively modern by ca. 10,000 yr B.P. in the early Holocene although a California juniper woodland persisted in the area until 8970 yr B.P. In contrast the fauna of the Hornaday Mountains, northwestern Sonora, increased dramatically in species richness after 4000 yr B.P. Although we are limited by poor taxonomic resolution and by insufficient knowledge of current distributions, the arthropod fauna may have been much more conservative than the regional flora during the last glacial/interglacial climatic cycle. Decreasing differences between modern and glacial climates (both temperature and precipitation) at lower latitudes and elevations may have resulted in minimal changes in the arthropod fauna of the Sonoran Desert lowlands.

    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.

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.

    Full Text Available Introduction and Aim. Although tobacco and alcohol use have declined substantially in the Australian community, substance use among prisoners remains high. The aim was to compare the smoking, drug, and alcohol characteristics, sociodemographic profile, and general health of Aboriginal and non-Aboriginal male prisoners in a smoking cessation intervention. Design and Methods. This study was a descriptive cross-sectional analysis of data from 425 male prisoners who joined a quit smoking trial conducted at 18 correctional centres in NSW and Queensland using data collected by standardised self-report instruments. Results. Average age was 33 years with 15% from Aboriginal descent. Compared to non-Aboriginal prisoners, Aboriginal prisoners were significantly more likely to have left school with no qualifications, to have been institutionalised as a child, to be previously incarcerated, and commenced smoking at a younger age. The tobacco use profile of both groups was similar; most of them had a medium to high level of nicotine dependence, smoked roll your own tobacco, and were “serious” about quitting. Discussion and Conclusion. Despite differences in terms of sociodemographic characteristics and offending history, the smoking characteristics of Aboriginal and non- Aboriginal prisoners were similar. Incarceration offers an opportunity to encourage smoking cessation and reduction of drug use.

    2006-01-01

    This is a summary report of the Aboriginal content of the Language and Culture theme at the Canadian Public Health Association's Second Canadian Conference on Literacy and Health. Our key premise is that Indigenous conceptualizations of literacy need to build on Indigenous understandings and perspectives. We support this premise through a review of the relevant literature in the disciplines of Aboriginal literacy, Indigenous education, health literacy, health promotion, and knowledge translation and our synthesis of the presentations, workshops, and discussions at the meeting. Key emergent themes include: the unique and culturally determined ways in which Aboriginal peoples and their languages conceptualize learning, education, and health; and the recognition that self-determination of language and learning are human rights. Aboriginal concepts of and approaches to literacy naturally link to and overlap with Aboriginal concepts of and approaches to health. The paper includes an overview of gaps in the field and an example of the way that research and practice can be brought together in the context of one First Nations community.

    1989-01-01

    Evaluation of Aboriginal Health Services (AHSs) has become a topic of importance to service providers and governments in recent years. This paper examines some of the difficulties AHSs have in conducting evaluation and presents an example of an inappropriate evaluation methodology as proposed by the Commonwealth Department of Aboriginal Affairs (DAA) in 1986. The paper examines the contradictory nature of the DAA proposal and the mistrust it has engendered in many AHSs. It then highlights some of the political difficulties in developing meaningful national and community health objectives as a basis for sound evaluation of health services. The paper concludes by identifying some of the processes whereby more appropriate evaluation methodologies might be developed and suggests that negotiation and consultation with the Aboriginal communities and their health services are imperative to successful evaluation.

    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. Drawing on interviews with Indigenous women performers and musical examples of their songs, I explore the impact of Aboriginalism on non-Indigenous expectations of Indigenous Australian women performing in contemporary music contexts, the strategies performers use to work within and against these constructions and my own relationship to Aboriginalism.

  11. Astronomical Symbolism in Australian Aboriginal Rock Art

    Norris, Ray P

    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.

    2012-01-01

    Aim To document the impact of late Quaternary pluvial events on plant movements between the coast and the Andes across the Atacama Desert, northern Chile. Location Sites are located along the lower and upper fringes of absolute desert (1100–2800 m a.s.l.), between the western slope of the Andes and the Coastal Ranges of northern Chile (24–26° S). Methods We collected and individually radiocarbon dated 21 rodent middens. Plant macrofossils (fruits, seeds, flowers and leaves) were identified and pollen content analysed. Midden assemblages afford brief snapshots of local plant communities that existed within the rodents' limited foraging range during the several years to decades that it took the midden to accumulate. These assemblages were then compared with modern floras to determine the presence of extralocal species and species provenance. Results Five middens span the last glacial period (34–21 ka) and three middens are from the last glacial–interglacial transition (19–11 ka). The remaining 13 middens span the last 7000 years. Coastal hyperarid sites exhibit low taxonomic richness in middens at 19.3, 1.1, 1.0, 0.9, 0.5 ka and a modern sample. Middens are also dominated by the same plants that occur today. In contrast, middens dated to 28.1, 21.3, 17.3, 3.7 and 0.5 ka contain more species, including Andean extralocals. Precordillera middens (c. 2700 m) show a prominent increase in plant macrofossil richness, along with the appearance of Andean extralocals and sedges at 34.5 and 18.9 ka. Six younger middens dated to 6.1–0.1 ka are similar to the modern local vegetation. Main conclusions Increased species richness and Andean extralocal plants occurred along the current lower fringes of absolute desert during the last glacial–interglacial transition and late Holocene. The absence of soil carbonates indicates the persistence of absolute desert throughout the Quaternary. Colonization by Andean plants could have been accomplished through long-distance seed

    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.

    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.

  1. 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

    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.

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

    Directory of Open Access Journals (Sweden)

    Mai T. Nguyen

    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.

  4. Letter - Reply: Meteors in Australian Aboriginal Dreamings

    Hamacher, Duane W.

    2011-06-01

    In response to the letter by Gorelli (2010) about Hamacher & Norris (2010), he is quite right about Aboriginal people witnessing impact events in Australia. There are several oral traditions regarding impact sites, some of which were probably witnessed, as Gorelli pointed out. The Henbury craters he mentions, with a young age of only ∼ 4200 years, have oral traditions that seem to describe a cosmic impact, including an aversion to drinking water that collects in the craters in fear that the fire-devil (which came from the sun, according to an Elder) would rain iron in them again. Other impact sites, such as Gosse's Bluff crater (Tnorala in the Arrernte language) and Wolfe Creek crater (Kandimalal in the Djaru language) have associated impact stories, despite their old ages (142 Ma and ∼0.3 Ma, respectively). In addition, many fireball and airburst events are described in Aboriginal oral traditions, a number of which seem to indicate impact events that are unknown to Western science. I have published a full treatise of meteorite falls and impact events in Australian Aboriginal culture that I would like to bring to the attention of Gorelli and WGN readers (Hamacher & Norris, 2009). Although our paper was published in the 2009 volume of Archaeoastronomy, it did not appear in print until just recently, which is probably why it has gone unnoticed. Recent papers describing the association between meteorites and Aboriginal cosmology (Hamacher, 2011) and comets in Aboriginal culture (Hamacher & Norris, 2011) have also been published, and would likely be of interest to WGN readers. I heartily agree with Gorelli that oral traditions are fast disappearing, taking with them a wealth of information about not only that peoples' culture, but also about past geologic and astronomical events, such as meteorite falls and cosmic impacts (a branch of the growing field of Geomythology). There is an old saying that "when a man dies, a library goes with him". This is certainly the

    The potential of risky sexual behaviors and adolescent unplanned pregnancy has become a primary issue in the health care system for aborigines in eastern Taiwan. Using aboriginal nurses to provide information on sexual behaviors may have potential in promoting healthy sexual practices among aborigines. The purposes of this study were to explore Taiwanese aboriginal nurses beliefs. attitudes, and values about sexuality. Several health centers in eastern Taiwan were randomly selected to recruit participants in the year 2000. A self-report questionnaire was administered to 206 female nurses (mean age = 28.4, SD = 7.4) who worked in various clinical units. The results revealed that aboriginal nurses hold moderately positive beliefs, attitudes, and values about sexuality. The conflict between aboriginal nurses' belief and value systems about sexuality was clear. A conflict between aboriginal nurses' value systems and patients behaviors also existed. Strategies to help aboriginal nurses to be more aware of their beliefs, attitudes, and values about sexuality should be an essential issue in the practice and education of nurses.

  13. 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.

    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.

    2015-02-01

    Full Text Available Aboriginal protest played a key role in undermining the celebratory settler-nationalism of the bicentennial in 1988. In the lead up to another major nationalist mobilisation, the centenary of the Gallipoli invasion on ANZAC Day 2015, extensive official efforts are being made to incorporate Aboriginal experiences into the day, through celebration of the role of Aboriginal people who served in Australia’s armed forces.   This article provides a critical analysis of the 2014 NAIDOC theme as a way of exploring some of the tensions in this process. The NAIDOC theme, ‘Serving Country: Centenary and Beyond’, presented a continuity between Aboriginal soldiers in WW1 and Aboriginal warriors who fought in defence of their land during the 19th Century Frontier Wars.   In contrast, this article argues that the real historical continuity is between the massacres on the frontier, which often involved Aboriginal troopers fighting for the colonial powers, and the invasions undertaken by Australian soldiers in WW1. New research documenting the horrific scale on which Aboriginal people were killed by Native Police in Queensland in the second half of the 19th Century is integrated with studies of the political economy of Australian settler-capitalism in this period. This analysis is used to demonstrate how capitalist class interests drove both the Frontier Wars and the development of an Australian regional empire, which was consolidated by the mobilisation of Australian troops in WW1.

    2016-01-01

    Every woman experiences the menopause transition period in a very individual way. Menopause symptoms and management are greatly influenced by socioeconomic status in addition to genetic background and medical history. Because of their very unique cultural heritage and often holistic view of health and well-being, menopause symptoms and management might differ greatly in aboriginals compared to non-aboriginals. Our aim was to investigate the extent and scope of the current literature in describing the menopause experience of aboriginal women. Our systematic literature review included nine health-related databases using the keywords 'menopause' and 'climacteric symptoms' in combination with various keywords describing aboriginal populations. Data were collected from selected articles and descriptive analysis was applied. Twenty-eight relevant articles were included in our analysis. These articles represent data from 12 countries and aboriginal groups from at least eight distinctive geographical regions. Knowledge of menopause and symptom experience vary greatly among study groups. The average age of menopause onset appears earlier in most aboriginal groups, often attributed to malnutrition and a harsher lifestyle. This literature review highlights a need for further research of the menopause transition period among aboriginal women to fully explore understanding and treatment of menopause symptoms and ultimately advance an important dialogue about women's health care.

    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.

    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 ...

    2015-06-01

    Full Text Available This paper examines key examples of writing about Australian Aboriginal art in the decades around 1900 specifically in relation to the way in which it is used to provide evidence for theories concerning the evolution of art. Analysis of published works by late nineteenth-century men of science reveals the main influences shaping their perceptions of Aboriginal art during this time and provides an early working definition of this emerging category. This paper confirms that turn-of-the-century European understandings of Aboriginal art were based on limited evidence mediated through a specifically ethnographic notion of ‘decorative art’.

  2. 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.

    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.

    Full Text Available Abstract The report on the Royal Commission on Aboriginal Peoples (1996, the Kelowna Accord announced in 2005 (five-billion dollars followed by its demise in 2006, and the settlement in 2006 for Aboriginal survivors of residential schools (1.9 billion dollars, are but some of the recent high-profile indicators of the challenges to Canada in dealing with the 500-year history of European contact with North America’s original inhabitants. While not without its challenges, the creation of Nunavut in 1999 stands apart from this history as a landmark for Inuit self-determination in Canada and a beacon of hope for other Aboriginal peoples. Building on the idea that educational change takes place within the intersecting socio-cultural contexts of the school and the larger world around it, and drawing on data from an eight-year series of design experiments in classrooms in the Baffin (now Qikiqtani region of Nunavut, this paper explores the potential of knowledge building and knowledge-building technologies to support powerful bilingual (Inuktitut/English and bicultural learning experiences for Aboriginal students. Résumé : Le rapport de la Commission royale sur les peuples autochtones (1996, l’Accord de Kelowna annoncé en 2005 (cinq milliards de dollars, suivi de son annulation en 2006, de même que le règlement de 2006 visant à indemniser les victimes de sévices infligés dans les pensionnats indiens (1,9 milliard de dollars, ne sont que quelques-uns des événements marquants récents qui témoignent des défis que le Canada doit relever en ce qui a trait à son histoire de 500 ans de contact entre les Européens et les Premières nations d’Amérique du Nord. Bien qu’elle ait comporté sa part de défis, la création du Nunavut en 1999 se démarque dans le cours de l’histoire en tant que point de repère pour l’autodétermination des Inuits au Canada et représente une lueur d’espoir pour les autres nations autochtones.

    Full Text Available 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.

    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.

    2013-02-01

    Researchers working with Aboriginal Australian partners are confronted with an array of historical, social, and political complexities which make it difficult to come to theoretical and methodological decisions. In this article, we describe a culturally safe and respectful framework that maintains the intellectual and theoretical rigor expected of academic research. As an Aboriginal woman and two non-Aboriginal women, we discuss the arguments and some of the challenges of using grounded theory methods in Aboriginal Australian contexts, giving examples from our studies of Aboriginal empowerment processes. We argue that the ethics of care and responsibility embedded in Aboriginal research methodologies fit well with grounded theory studies of Aboriginal social processes. We maintain that theory development grounded in data provides useful insights into the processes for raising the health, well-being, and prosperity of Aboriginal Australians.

    Two recent rulings by the British Columbia Court of Appeal have placed the onus for consultation and accommodation with Aboriginal peoples affected by resource development on the shoulders of industry. The authors discussed this new responsibility for the petroleum industry from a legal perspective. The first part of the document consists of an overview of Aboriginal and treaty rights. The Supreme Court of Canada's justification test of infringement of Aboriginal and treaty rights were reviewed in the second part. In part three, the authors reviewed the scope and nature of consultation, as well as the various sources for duty of consultation. These sources include administrative law, legislation, and potential new sources of the law of fiduciaries, and the 1982 Constitution Act between Aboriginal peoples and industry. Part four reviewed the Haida decisions and the duty of consultation with Aboriginal peoples as formulated by the British Columbia Court of Appeal. The impact of this decision on the petroleum industry was then discussed. refs.

  14. Memorialising the Past: Is there an 'Aboriginal' Way?

    Directory of Open Access Journals (Sweden)

    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.

    Livestock was often released onto remote Southern Ocean islands as a food source for shipwreck survivors during the industrial whaling and sealing era. Although animals were put ashore at nearby Isles Kerguelen and Crozet, the historical records make no mention of domesticated livestock ever being set ashore at Heard Island between 1855 and 1882. Here we report a pig ( Sus scrofa) mandible discovered amongst other bones and artefacts in an `elephanters' midden found at Spit Bay, Heard Island. The find provides very strong evidence a live pig was shipped ashore and eaten as part of the sealers meagre provisions. Archaeological investigations of middens at other sealing locations could produce new insights into the dietary habits of these men.

    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.

    Descriptions of cosmic impacts and meteorite falls are found throughout Australian Aboriginal oral traditions. In some cases, these texts describe the impact event in detail, sometimes citing the location, suggesting that the events were witnessed. We explore whether cosmic impacts and meteorite falls may have been witnessed by Aboriginal Australians and incorporated into their oral traditions. We discuss the complications and bias in recording and analysing oral texts but suggest that these texts may be used both to locate new impact structures or meteorites and model observed impact events. We find that, while detailed Aboriginal descriptions of cosmic impacts are abundant in the literature, there is currently no physical evidence connecting these accounts to impact events currently known to Western science.

  20. 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.

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

    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.

    Full Text Available Abstract Background Heart disease is a leading cause of the gap in burden of disease between Aboriginal and non-Aboriginal Australians. Our study investigated short- and long-term mortality after admission for Aboriginal and non-Aboriginal people admitted with acute myocardial infarction (AMI to public hospitals in New South Wales, Australia, and examined the impact of the hospital of admission on outcomes. Methods Admission records were linked to mortality records for 60047 patients aged 25–84 years admitted with a diagnosis of AMI between July 2001 and December 2008. Multilevel logistic regression was used to estimate adjusted odds ratios (AOR for 30- and 365-day all-cause mortality. Results Aboriginal patients admitted with an AMI were younger than non-Aboriginal patients, and more likely to be admitted to lower volume, remote hospitals without on-site angiography. Adjusting for age, sex, year and hospital, Aboriginal patients had a similar 30-day mortality risk to non-Aboriginal patients (AOR: 1.07; 95% CI 0.83-1.37 but a higher risk of dying within 365 days (AOR: 1.34; 95% CI 1.10-1.63. The latter difference did not persist after adjustment for comorbid conditions (AOR: 1.12; 95% CI 0.91-1.38. Patients admitted to more remote hospitals, those with lower patient volume and those without on-site angiography had increased risk of short and long-term mortality regardless of Aboriginal status. Conclusions Improving access to larger hospitals and those with specialist cardiac facilities could improve outcomes following AMI for all patients. However, major efforts to boost primary and secondary prevention of AMI are required to reduce the mortality gap between Aboriginal and non-Aboriginal people.

    Science.gov (United States)

    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.

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.

    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.

  13. On the Astronomical Knowledge and Traditions of Aboriginal Australians

    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

    Despite improvements between 2001 and 2011, Canada’s Aboriginal population continues to underperform in the labour market. The Aboriginal educational attainment gap is often seen as the major source of these disparities. Using data from the 2011 National Household Survey, projections of Aboriginal population growth, and forecasts of aggregate economic conditions, we estimate the economic impact of closing the educational attainment gap by 2031. We find that the benefits of achieving such a fe...

    There are few empirical studies about the role of Aboriginal sporting organisations in promoting wellbeing. The aim of the present study was to understand the impact of an Aboriginal community sporting team and its environment on the social, emotional and physical wellbeing of young Aboriginal men, and to identify barriers and motivators for participation. A literature review of the impact of sport on the health and wellbeing of Aboriginal participants was conducted. This informed a qualitative study design with a grounded theory approach. Four semistructured interviews and three focus groups were completed with nine current players and five past players of the Fitzroy Stars Football Club to collect data about the social, emotional and physical wellbeing impact of an Aboriginal football team on its Aboriginal players. Results of the interviews were consistent with the literature, with common concepts emerging around community connection, cultural values and identity, health, values, racism and discrimination. However, the interviews provided further detail around the significance of cultural values and community connection for Aboriginal people. The complex nature of social connections and the strength of Aboriginal community networks in sports settings were also evident. Social reasons were just as important as individual health reasons for participation. Social and community connection is an important mechanism for maintaining and strengthening cultural values and identity. Barriers and motivators for participation in Aboriginal sports teams can be complex and interrelated. Aboriginal sports teams have the potential to have a profound impact on the health of Aboriginal people, especially its players, by fostering a safe and culturally strengthening environment and encompassing a significant positive social hub for the Aboriginal community.

    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.

    CERN Document Server

    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 ...

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

    Directory of Open Access Journals (Sweden)

    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.

    BACKGROUND: There is limited knowledge concerning chronic bronchitis (CB) in Canadian Aboriginal peoples. OBJECTIVE: To determine the prevalence (crude and adjusted) of CB and its associated risk factors in Canadian Aboriginal children and youth six to 14 years of age. METHODS: Data from the cross-sectional Aboriginal Peoples Survey were analyzed in the present study. Logistic regression analysis was used to determine risk factors influencing the prevalence of CB among Aboriginal children and youth. The balanced repeated replication method was used to compute standard errors of regression coefficients to account for clustering inherent in the study design. The outcome of interest was based on the question: “Have you been told by a doctor, nurse or other health professional that you have chronic bronchitis?” Demographics, environment and population characteristics (predisposing and enabling resources) were tested for an association with CB. RESULTS: The prevalence of CB was 3.1% for boys and 2.8% for girls. Other significant risk factors of CB were age (OR 1.38 [95% CI 1.24 to 1.52] for 12 to 14 year olds versus six to eight year olds), income (OR 2.28 [95% CI 2.02 to 2.59] for income category <$25,000/year versus ≥$85,000/year), allergies (OR 1.96 [95% CI 1.78 to 2.16] for having allergies versus no allergies), asthma (OR 7.61 [ 95% CI 6.91 to 8.37] for having asthma versus no asthma) and location of residence (rural/urban and geographical location). A significant two-way interaction between sex and body mass index indicated that the relationship between the prevalence of CB and body mass index was modified by sex. DISCUSSION: The prevalence of CB was related to well-known risk factors among adults, including older age and lower annual income. PMID:23248806

    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.

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

    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.

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.

  6. Forestry and Road Development: Direct and Indirect Impacts from an Aboriginal Perspective.

    Directory of Open Access Journals (Sweden)

    Tom M. Beckley

    2012-12-01

    Full Text Available The forest industry is a significant contributor to the development of roads and most are constructed on Aboriginal territories. Many Aboriginal communities are isolated both socially and economically and Aboriginal cultures are often described as having inherent socio-environmental relationships. Aboriginal communities, therefore, may be the most likely to benefit and be most vulnerable to the impacts of road development. We use a case study approach to explore how an Aboriginal community interprets and responds to the increasing development of roads in its territory. The results are interpreted using the theory of access in order to frame the interactions between people and nature within a cohesive system which includes elements which are spatially located, flow, interact, and can be disturbed. The dominant themes discussed as being affected by the influence of roads on access included issues of the following nature: Aboriginal, hunting, foreign, territorial and environmental. Issues pertaining to Aboriginal actors as opposed to foreign actors such as the industry or non-aboriginal hunters and fishers dominated discussions. Although the positive effects provided by roads were alluded to, focus tended towards the affected relationships and ties between the territory, the environment and Aboriginal members. Roads are associated with changes in traditional roles and practices which benefit individualistic behaviors. The access mechanisms mediating and controlling the use of resources through traditional norms and roles such as sharing, asking permission, and helping in the practice of traditional activities no longer apply effectively. Changes in the traditional spatial organization of the territory have minimized the influence of knowledge, identity, and negotiation in mediating access among communities. Results highlight that conflicts have thus resulted between and among Aboriginal communities. Also, perception of the role of the environment

    In response to the enduring "deficit" approach to the educational attainment of Aboriginal students in North America, we hypothesized that academic underperformance is related to a cultural mismatch between Aboriginal students' cultural background, which emphasizes connectedness and interdependence, and the mainstream White model of education, which focuses on independence and assertiveness. The participants included virtually all the secondary students (N = 115) in the Naskapi community of Kawawachikamach, Quebec, Canada. We obtained self-reports of identification with Aboriginal and White culture, teacher reports of assertiveness, and official grades. We found that high identification with either Aboriginal or White culture was related to higher grades, regardless of whether the students were perceived as assertive by their teacher. Conversely, at low levels of cultural identification toward Aboriginal or White culture, being perceived as low in assertiveness by one's teacher predicted lower grades. This suggests that both high cultural identification and assertiveness can contribute to enhancing the educational outcomes of Aboriginal students, but that Aboriginal students with low levels of both cultural identification and assertiveness are at particular risk as they are mismatched with the culture of mainstream schools and do not benefit from the protective effects of identity. The relationships among identity, cultural values, and academic performance point to the need to reject the notion of an inherent deficit in education among Aboriginal youths in favor of a different framework in which success can be attained when alternative ways of being are fostered and nurtured in schools.

    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.

    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.

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

    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.

    Obesity prevention efforts in Aboriginal (First Nations, Métis, or Inuit) communities in Canada should focus predominantly on children given their demographic significance and the accelerated time course of occurrence of type 2 diabetes mellitus in the Aboriginal population. A socioecological model to address childhood obesity in Aboriginal populations would focus on the numerous environments at different times in childhood that influence weight status, including prenatal, sociocultural, family, and community environments. Importantly, for Aboriginal children, obesity interventions need to also be situated within the context of a history of colonization and inequities in the social determinants of health. This review therefore advocates for the inclusion of a historical perspective and a life-course approach to obesity prevention in Aboriginal children in addition to developing interventions around the socioecological framework. We emphasize that childhood obesity prevention efforts should focus on promoting maternal health behaviours before and during pregnancy, and on breastfeeding and good infant and child nutrition in the postpartum and early childhood development periods. Ameliorating food insecurity by focusing on improving the sociodemographic risk factors for it, such as increasing income and educational attainment, are essential. More research is required to understand and measure obesogenic Aboriginal environments, to examine how altering specific environments modifies the foods that children eat and the activities that they do, and to examine how restoring and rebuilding cultural continuity in Aboriginal communities modifies the many determinants of obesity. This research needs to be done with the full participation of Aboriginal communities as partners in the research.

    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.

    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.

    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

    The night sky played an important role in the social structure, oral traditions, and cosmology of the Arrernte and Luritja Aboriginal cultures of Central Australia. A component of this cosmology relates to meteors, meteorites, and impact craters. This paper discusses the role of meteoritic phenomena in Arrernte and Luritja cosmology, showing not only that these groups incorporated this phenomenon in their cultural traditions, but that their oral traditions regarding the relationship between meteors, meteorites and impact structures suggests the Arrernte and Luritja understood that they are directly related.

  6. “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.

  7. Treatment Issues for Aboriginal Mothers with Substance Use Problems and Their Children

    2014-01-01

    In many cultures, approximately one third of people with drug dependence are women of child-bearing age. Substance use among pregnant and parenting women is a major public health concern. Aboriginal people have some of the highest rates of substance abuse in Canada, increasing concern for detrimental health impacts, including those for women and their children. For many women, substance abuse offers a means of coping with trauma, such as childhood abuse, partner violence, and, for Aboriginal women, the intergenerational effects of colonization. In this paper, we review treatment issues for Aboriginal mothers with substance use problems and their children. We discuss gender-specific issues in substance abuse, the need for women-specific treatment, the impact of substance abuse on children and parenting, the additional risks for Aboriginal women and children, and the need for integrated programs (those that integrate pregnancy-, parenting-, and child-related services with women-specific addiction treatment). We describe New Choices as an example of an integrated program, review research on existing treatment for Aboriginal mothers with substance use issues, and describe Sheway as a promising integrated program for Aboriginal women with substance abuse issues and their young children. There are few treatment programs specifically for Aboriginal mothers with substance use issues and their children and very little research on their effectiveness. Based on our review of existing evidence, we offer recommendations for future research and practice. PMID:24976814

    Full Text Available This paper suggests some, but not all, the core titles needed for developing a public library collection that would reflect the diversity and complexity of the lives of Aboriginal women in Canada. The titles include major authors, essential titles, journals, magazines, indexes, databases, reference books, websites, film, music, and spoken word as well as some recommended collection sources. The works reveal an emerging literature and cultural production for, by, and about Aboriginal women that steers away from pathologizing their lives as discussed in the l998 Status of Women in Canada report Aboriginal Women in Canada: Strategic Research Directions for Policy Development. Library customers who are seeking a better understanding of the lives of Aboriginal women in Canada, or Aboriginal women who are seeking materials that reflect the strengths, challenges, reality, and dreams of their lives, should be able to expect a core collection in the public libraries of the communities in which they live. This paper will outline some of the arguments for developing a core collection of work for, and about, Aboriginal women in Canada, and will suggest some criteria and selection sources critical for this collection. For this paper, Aboriginal women in Canada include women who identify themselves as First Nation, Inuit and Metis.

  9. 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.

  10. Offshore oil and gas and coastal British Columbia : Aboriginal rights, title and interests

    Porter, D. [First Nations Summit, West Vancouver, BC (Canada)

    2006-07-01

    This presentation discussed the legal duty of offshore proponents in the oil and gas industry to consult with Aboriginal nations. The Crown court's support for Aboriginal title to ocean areas within proposed offshore regions was also discussed, and Aboriginal rights to manage ocean resources were outlined. Haida and Taku River Tlingit legal decisions have confirmed both a constitutional and fiduciary duty for the Crown to consult with Aboriginal nations who assert their rights or title to lands subject to development. Resource rights granted without meaningful consultation with Aboriginal nations can be challenged, which may result in legal and financial liability for resource companies. A consultative process that addresses ownership, capacity and benefit sharing must be developed so that Aboriginal governments can participate in the design and development of appropriate fiscal and regulatory regimes. The developed regime must consider benefit and revenue sharing, as well as the integration of traditional knowledge within western science for the lifetime of any project. All decision-making bodies must include participation from Aboriginal groups. Mechanisms must also be developed to mitigate the environmental and socio-economic consequences of resource development. Impact and benefit agreements must be negotiated with coastal nations. Dissatisfaction with the concept of consultation processes has led first nations to reconsider the role that they must play in ensuring that oil and gas developments in the coastal regions of British Columbia do not negatively impact on their communities. It was noted that Inuit land claims reserve special rights for the Inuit over 18,800 miles of tidal waters. Earlier attempts by Aboriginal societies to assert their right to control their own ocean resources free from governmental interference were also discussed. It was concluded that litigation of Aboriginal rights and title poses serious challenges to offshore oil and gas

    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

    We have examined 56 unrelated individuals from Malaysian aborigines for their DNA polymorphism of the HLA-B gene by sequence specific oligonucleotide probe (SSO) method. Using the SSO hybridization, we found that one specific DNA allele with a B*1513 like pattern of epitope combination (ECB1513) was dominant among the Melayu Asli (Af = 41.9%) and the Senoi (Af = 24%). To determine the nucleotide sequences of ECB1513, a DNA fragment spanning from the beginning of exon 1 to the middle of exon 4 of the HLA-B gene was amplified by polymerase chain reaction (PCR) from two ECB1513 positive individuals, and the PCR products were cloned and sequenced. This sequencing analysis confirmed that ECB1513 was identical to HLA-B*1513 in exon 1, 2, 3, and 4. Amino acid sequence of this major allele, HLA-B*1513, in the aborigines especially around the peptide binding groove (B and F pockets), was compared with that of African B*5301 that had been suggested to confer resistance to malaria infection in Africa. The amino acid residues composing of the F pocket were completely identical in B*1513 and B*5301. These observations suggest that a common environmental factor, the malaria infection, might have independently enhanced the selection of functional change in the polymorphic portion of HLA-B gene in Africa and in South-East Asia.

    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.

    Poor access to prenatal care for Aboriginal people is well documented, and is explicated as an unethical barrier to care resulting from colonial and neocolonial values, attitudes, and practices. A postcolonial standpoint, participatory research principles, and a case study design were used to investigate 2 Aboriginal organizations' experiences improving care for pregnant and parenting Aboriginal people. Data were collected through exploratory interviews and small-group discussions with purposefully selected community leaders, providers, and community members. The study found that safety in healthcare relationships and settings, and responsiveness to individuals' and families' unique experiences and capacities must be brought into the forefront of care. Results suggest that the intention of care must be situated within a broader view of colonizing relations to improve early access to, and relevance of, care during pregnancy and parenting for Aboriginal people.

    2016-11-01

    Full Text Available Background: The Aboriginal people of Australia have much poorer health and social indicators and a substantial life expectancy gap compared to other Australians, with premature cardiovascular disease a major contributor to poorer health. This article draws on research undertaken to examine cardiovascular disparities and focuses on ways in which primary care practitioners can contribute to reducing cardiovascular disparities and improving Aboriginal health. Methods: The overall research utilised mixed methods and included data analysis, interviews and group processes which included Aboriginal people, service providers and policymakers. Workshop discussions to identify barriers and what works were recorded by notes and on whiteboards, then distilled and circulated to participants and other stakeholders to refine and validate information. Additional engagement occurred through circulation of draft material and further discussions. This report distils the lessons for primary care practitioners to improve outcomes through management that is attentive to the needs of Aboriginal people. Results: Aspects of primordial, primary and secondary prevention are identified, with practical strategies for intervention summarised. The premature onset and high incidence of Aboriginal cardiovascular disease make prevention imperative and require that primary care practitioners understand and work to address the social underpinnings of poor health. Doctors are well placed to reinforce the importance of healthy lifestyle at all visits to involve the family and to reduce barriers which impede early care seeking. Ensuring better information for Aboriginal patients and better integrated care for patients who frequently have complex needs and multi-morbidities will also improve care outcomes. Conclusion: Primary care practitioners have an important role in improving Aboriginal cardiovascular care outcomes. It is essential that they recognise the special needs of their

    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.

    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

    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.

    At the core of the Double Shell concept is the kinetic energy transfer from the outer shell to the inner shell via collision. This collision sets both the implosion shape of the inner shell, from imprinting of the shape of the outer shell, as well as the maximum energy available to compress the DT fuel. Therefore, it is crucial to be able to control the time-dependent shape of the outer shell, such that the outer shell is nominally round at the collision time. We present the experiment results from our sub-scale ( 1 MJ) NIF outer-shell only shape tuning campaign, where we vary shape by changing a turn-on time delay between the same pulse shape on the inner and outer cone beams. This type of shape tuning is unique to this platform and only possible since the Double Shell design uses a single-shock drive (4.5 ns reverse ramp pulse). The outer-shell only targets used a 5.75 mm diameter standard near-vacuum NIF hohlraum with 0.032 mg/cc He gas fill, and a Be capsule with 0.4% uniform Cu dopant, with 242 um thick ablator. We also present results from a third outer-shell only shot used to measure shell trajectory, which is critical in determining the shell impact time.

    Full Text Available Context Aboriginal and Torres Strait Islanders (Aboriginal account for approximately 3% of the Australian population. They have the poorest health, economic and social outcomes. Higher notification rates of hepatitis C antibodies (anti-HCV have been reported among Aboriginal compared with non-Aboriginal people. The identification of Aboriginal people in national surveillance has some weaknesses, with only four of the eight jurisdictions included in national reporting. To address some of these limitations, we aim to estimate the pooled prevalence of anti-HCV among Aboriginal people in Australia. Evidence Acquisition We searched the databases: Pubmed, Web of Science and Informit, and the New South Wales and Northern Territory Public Health Bulletins. A study was included if it reported the number of Aboriginal people testing positive for anti-HCV and the number tested for anti-HCV. A meta-analysis by population-group was conducted if three or more studies reported a prevalence estimate. Variables included: author, year of publication, study design, study period, gender (female, male, age, population group (Aboriginal people in prison, Aboriginal people who inject drugs, number testing anti-HCV positive, number tested for anti-HCV and prevalence (%. Due to a long time period, we separated the studies estimating the prevalence anti-HCV among Aboriginal people in prison into two time periods, 1994 - 2004 and 2005 - 2012. Results Overall, 15 studies met our inclusion criteria. Among Aboriginal people in prison, the pooled prevalence of anti-HCV was 18.1% (95%CI: 6.6 - 29.7. The pooled prevalence among Aboriginal people in prison was 25.7% (95%CI: 4.1-47.3 in studies published between 1994 - 2004 and 14.5% (95%CI: 1.7 - 27.3 in studies published from 2005 - 2012. The pooled prevalence of anti-HCV was 58.7% (95%CI: 53.9 - 63.5 among Aboriginal people who inject drugs and 2.9% (95%CI: 0.30 - 6.1 among Aboriginal people who did not inject drugs, however

    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

  4. Biomes of western North America at 18,000, 6000 and 0 14C yr BP reconstructed from pollen and packrat midden data

    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

    Aboriginal Australians are at higher risk of developing certain types of cancer and, once diagnosed, they have poorer outcomes than their non-Aboriginal counterparts. Lower access to cancer screening programmes, deficiencies in treatment and cultural barriers contribute to poor outcomes. Additional logistical factors affecting those living in rural areas compound these barriers. Cancer support groups have positive effects on people affected by cancer; however, there is limited evidence on peer-support programmes for Aboriginal cancer patients in Australia. This paper explores the roles played by an Aboriginal women's cancer support network operating in a regional town in Western Australia. Data were collected through semi-structured interviews with 24 participants including Aboriginal and mainstream healthcare service providers, and network members and clients. Interviews were audiotaped and transcribed verbatim. Transcripts were subjected to inductive thematic analysis. Connecting and linking people and services was perceived as the main role of the network. This role had four distinct domains: (i) facilitating access to cancer services; (ii) fostering social interaction; (iii) providing a culturally safe space; and (iv) building relationships with other agencies. Other network roles included providing emotional and practical support, delivering health education and facilitating engagement in cancer screening initiatives. Despite the network's achievements, unresolved tensions around role definition negatively impacted on the working relationship between the network and mainstream service providers, and posed a threat to the network's sustainability. Different perspectives need to be acknowledged and addressed in order to build strong, effective partnerships between service providers and Aboriginal communities. Valuing and honouring the Aboriginal approaches and expertise, and adopting an intercultural approach are suggested as necessary to the way forward.

    Full Text Available BACKGROUND: Trachoma is the leading infectious cause of blindness due to conjunctival infection with Chlamydia trachomatis. The presence of active trachoma and evidence of infection are poorly correlated and a strong immunologically-mediated inflammatory response means that clinical signs last much longer than infection. This population-based study in five Aboriginal communities endemic for trachoma in northern Australia compared a fine grading of clinical trachoma with diagnostic positivity and organism load. METHODS: A consensus fine grading of trachoma, based on clinical assessment and photograding, was compared to PCR, a lipopolysacharide (LPS-based point-of-care (POC and a 16S RNA-based nucleic acid amplification test (NAAT. Organism load was measured in PCR positive samples. RESULTS: A total of 1282 residents, or 85.2% of the study population, was examined. Taking the findings of both eyes, the prevalence of trachomatous inflammation-follicular (TF in children aged 1-9 years was 25.1% (96/383 of whom 13 (13.7% were PCR positive on the left eye. When clinical data were limited to the left eye as this was tested for PCR, the prevalence of TF decreased to 21.4% (82/383. The 301 TF negative children, 13 (4.3% were PCR positive. The fine grading of active trachoma strongly correlated with organism load and disease severity (rs = 0.498, P = 0.0004. Overall, 53% of clinical activity (TF(1 or TF(2 and 59% of PCR positivity was found in those with disease scores less than the WHO simplified grade of TF. CONCLUSION: Detailed studies of the pathogenesis, distribution and natural history of trachoma should use finer grading schemes for the more precise identification of clinical status. In low prevalence areas, the LPS-based POC test lacks the sensitivity to detect active ocular infection and nucleic acid amplification tests such as PCR or the 16S-RNA based NAAT performed better. Trachoma in the Aboriginal communities requires specific control

    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.

    2004-05-01

    In this study, a series of focus groups were conducted to gain an understanding of the nature of stress among Canadian Aboriginal women and men living with diabetes. Specifically, attention was given to the meanings Aboriginal peoples with diabetes attach to their lived experiences of stress, and the major sources or causes of stress in their lives. The key common themes identified are concerned not only with health-related issues (i.e. physical stress of managing diabetes, psychological stress of managing diabetes, fears about the future, suffering the complications of diabetes, and financial aspects of living with diabetes), but also with marginal economic conditions (e.g. poverty, unemployment); trauma and violence (e.g. abuse, murder, suicide, missing children, bereavement); and cultural, historical, and political aspects linked to the identity of being Aboriginal (e.g. 'deep-rooted racism', identity problems). These themes are, in fact, acknowledged not as mutually exclusive, but as intertwined. Furthermore, the findings suggest that it is important to give attention to diversity in the Aboriginal population. Specifically, Métis-specific stressors, as well as female-specific stressors, were identified. An understanding of stress experienced by Aboriginal women and men with diabetes has important implications for policy and programme planning to help eliminate or reduce at-risk stress factors, prevent stress-related illnesses, and enhance their health and life quality.

    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.

    Previous research revealed a 6-fold higher incidence of tuberculosis (TB) amongst aborigines compared to Han Chinese in Taiwan. To investigate the reasons for this disparity, we genotyped Mycobacterium tuberculosis (MTB) strains obtained from members of different aboriginal tribes in different geographical regions of Taiwan by using molecular methods. In total, 177 isolates of MTB collected from patients at four hospitals in Taiwan from January 2006 to December 2011 were analysed by spoligotyping, mycobacterial interspersed repetitive unit-variable number tandem-repeat (MIRU-VNTR) typing. The most prevalent strains in the eastern and central regions of Taiwan were Beijing (45.7% in eastern) and Haarlem (39.1% in eastern, 37.1% in central) lineages, whereas in southern regions the most prevalent strains were EAI (47.7%) and Haarlem (20.5%) lineages. The high prevalence of EAI in southern Taiwan aborigines may be closely associated with Austronesian culture. This study provides a first overview of the M. tuberculosis strains circulating in aboriginal populations in Taiwan. The high prevalences of certain MTB lineages within aboriginal sub-populations suggest that transmission of MTB may have been restricted to close contacts.

    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.

    The goal of this exploratory community-based participatory action research project was twofold: to determine how urban Aboriginal youth identify their health needs within a culturally centred model of health and wellness, and to create new knowledge and research capacity by and with urban Aboriginal youth and urban Aboriginal health-care providers. A mixed-method approach was employed to examine these experiences using talking circles and a survey. The study contributes to anticolonial research in that it resists narratives of dis(ease) put forth through neocolonial research paradigms.A key focus was the development of strategies that address the aspirations of urban Aboriginal youth, laying foundations upon which their potential in health and wellness can be nurtured, supported, and realized. The study contributes to a new narrative of the health of urban Aboriginal youth within a culturally centred and culturally safe framework that acknowledges their strong connection to their Indigenous lands, languages, and traditions while also recognizing the spaces between which they move.

    The authors critically examine the relevance of postcolonial theoretical perspectives to nursing research in the area of Aboriginal health. They discuss key theoretical underpinnings of postcolonial theory, citing differences and commonalities in postcolonial theory, postcolonial indigenous thinking, and other forms of critical theory. Drawing on insights from Aboriginal scholars, they critique the relevance of postcolonial discourses to issues of concern to Aboriginal peoples, and the potential limitations of those discourses. They then consider the implications of conducting research that is informed by postcolonial perspectives. They argue that postcolonial perspectives provide direction for research with Aboriginal communities in 4 interrelated ways. These are focused on (a) issues of partnership and "voice" in the research process, (b) a commitment to engaging in praxis-oriented inquiry, (c) understanding how continuities from the past shape the present context of health and health care, and (d) the colonizing potential of research. The authors draw attention to the concept of cultural safety as an instrument for incorporating postcolonial perspectives into the realm of nursing. To illustrate applications of postcolonial theory, they give examples from recent research conducted in partnership with Aboriginal communities. Although postcolonial theories are relatively new in nursing discourses, they provide a powerful analytical framework for considering the legacy of the colonial past and the neocolonial present as the context in which health care is delivered.

    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 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.

    Aboriginal Australians represent one of the oldest continuous cultures outside Africa, with evidence indicating that their ancestors arrived in the ancient landmass of Sahul (present-day New Guinea and Australia) ~55 thousand years ago. Genetic studies, though limited, have demonstrated both the uniqueness and antiquity of Aboriginal Australian genomes. We have further resolved known Aboriginal Australian mitochondrial haplogroups and discovered novel indigenous lineages by sequencing the mitogenomes of 127 contemporary Aboriginal Australians. In particular, the more common haplogroups observed in our dataset included M42a, M42c, S, P5 and P12, followed by rarer haplogroups M15, M16, N13, O, P3, P6 and P8. We propose some major phylogenetic rearrangements, such as in haplogroup P where we delinked P4a and P4b and redefined them as P4 (New Guinean) and P11 (Australian), respectively. Haplogroup P2b was identified as a novel clade potentially restricted to Torres Strait Islanders. Nearly all Aboriginal Australian mitochondrial haplogroups detected appear to be ancient, with no evidence of later introgression during the Holocene. Our findings greatly increase knowledge about the geographic distribution and phylogenetic structure of mitochondrial lineages that have survived in contemporary descendants of Australia’s first settlers.

    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.

    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.

  6. Multiple shells in IRC+10216: shell properties

    Mauron, N.; Huggins, P. J.

    2000-07-01

    We report on the properties of the multiple shells in the circumstellar envelope of IRC+10216, using deep optical imaging, including data from the Hubble Space Telescope. The intensity profiles confirm the presence of thin ( ~ 0farcs5 -3'' ec), limb-brightened shells in the envelope, seen in stellar and ambient Galactic light scattered by dust. The shells are spaced at irregular intervals of ~ 5'' ec-20'' ec, corresponding to time scales of 200-800 yr, although intervals as short as ~ 1'' ec (40 yr) are seen close to the star. The location of the main shells shows a good correlation with high-resolution, molecular line maps of the inner envelope, indicating that the dust and gas are well coupled. The shell/intershell density contrast is typically ~ 3, and we find that the shells form the dominant mass component of the circumstellar envelope. The shells exhibit important evolutionary effects: the thickness increases with increasing radius, with an effective dispersion velocity of 0.7 km s-1 and there is evidence for shell interactions. Despite the presence of bipolar structure close to the star, the global shell pattern favors a roughly isotropic, episodic mass loss mechanism, with a range of time scales.

    Zubaran, Carlos; Foresti, Katia; de Moore, Gregory

    2013-12-01

    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.

  8. Environment and morphology in Australian Aborigines: a re-analysis of the Birdsell database.

    Gilligan, Ian; Bulbeck, David

    2007-09-01

    Pursuant to his major research interest in the cultural ecology of hunter-gatherers, Birdsell collected an unparalleled body of phenotypic data on Aboriginal Australians during the mid twentieth century. Birdsell did not explicitly relate the geographic patterning in his data to Australia's climatic variation, instead arguing that the observable differences between groups reflect multiple origins of Australian Aborigines. In this article, bivariate correlation and multivariate analyses demonstrate statistically significant associations between climatic variables and the body build of Australians that are consistent with the theoretical expectations of Bergmann's and Allen's rules. While Australian Aborigines in comparison to Eurasian and New World populations can be generally described as long-headed, linear in build, and characterized by elongated distal limbs, the variation in this morphological pattern across the continent evidently reflects biological adaptation to local Holocene climates. These results add to a growing body of evidence for the role of environmental selection in the development of modern human variation.

  9. Influences of indigenous language on spatial frames of reference in Aboriginal English

    2014-06-01

    The Aboriginal English spoken by Indigenous children in remote communities in the Northern Territory of Australia is influenced by the home languages spoken by themselves and their families. This affects uses of spatial terms used in mathematics such as `in front' and `behind.' Speakers of the endangered Indigenous Australian language Iwaidja use the intrinsic frame of reference in contexts where speakers of Standard Australian English use the relative frame of reference. Children speaking Aboriginal English show patterns of use that parallel the Iwaidja contexts. This paper presents detailed examples of spatial descriptions in Iwaidja and Aboriginal English that demonstrate the parallel patterns of use. The data comes from a study that investigated how an understanding of spatial frame of reference in Iwaidja could assist teaching mathematics to Indigenous language-speaking students. Implications for teaching mathematics are explored for teachers without previous experience in a remote Indigenous community.

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

    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.

    2016-02-01

    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.

    Barton, Sylvia S

    2008-09-01

    A narrative inquiry approach was used to explore the experience of Aboriginal people living with type 2 diabetes mellitus in a rural community. Narrative inquiry based on hermeneutic phenomenological philosophy was the methodology used to guide the research. A purposive sample of 4 persons of Nuxalk ancestry living in Bella Coola, Canada, were selected for their ability to present rich life narratives and to reveal meaning in their particular diabetes stories. Three key insights or overarching analytical interpretations emerged and could contribute broadly to Aboriginal health research. The focus of the article is the expansion of our understanding of diabetes within a specific cultural context. The discussion connects various philosophical, epistemological, and methodological orientations to research with Aboriginal people living with diabetes.

    Full Text Available Including Aboriginal women in qualitative health research expands our understanding of factors that contribute to their health and well-being. 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.

    2015-08-01

    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.

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

    McLaughlin, D. (Northern Land Council, Darwin (Australia))

    1985-04-01

    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.

    Andersson, Neil; Ledogar, Robert J

    2008-01-01

    CIET started supporting Canadian Aboriginal community-based researchers of resilience in 1995. An evolving approach to Aboriginal resilience used a combination of standard instruments and questionnaires of local design. Over the years, CIET measured personal assets like sense of coherence, spirituality, knowledge, pride in one's heritage, mastery or self-efficacy, self-esteem, low levels of distress, involvement in traditional ways and activities, church attendance. Other indicators reflected the social dimension of resilience: feeling supported; parental care and support; parental monitoring, attitudes, and example; peer support; and support from the wider community.Pride in one's heritage, self-esteem, low distress, and mastery were measurable personal assets of resilient Aboriginal youth in a variety of cultures and circumstances. Early efforts to link resilience with specific features of culture or spirituality did not meet with success - largely reflecting failure to ask the right questions. Parental care and support, parental monitoring, parental attitudes, and parental example clearly supported the resilient Aboriginal youth in most settings. But peers are an even stronger influence, critical in relation to different types of behaviour from smoking to drinking to substance abuse to violence, unsafe sex, and suicidal tendencies. More generally, having someone to confide in, to count on in times of crisis, someone to give advice and someone who makes one feel cared for are important factors in youth resilience and something that communities can help to provide even where the family is not the support it should be and where peers are more of a hindrance than a help.CIET currently supports three resilience research projects involving Aboriginal youth in Canada: suicide prevention, reduction of HIV risk, and reduction of domestic violence. The latest resilience measurement tools include enculturation and revised approaches to Aboriginal spirituality.

    Clarke, Philip A.

    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.

  19. An Aboriginal Australian Record of the Great Eruption of Eta Carinae

    CERN Document Server

    Hamacher, Duane W

    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.

  20. Colonization in North American Arid Lands: The Journey of Agarito (Berberis trifoliolata) Revealed by Multilocus Molecular Data and Packrat Midden Fossil Remains

    2017-01-01

    Here we conduct research to understand the evolutionary history of a shrubby species known as Agarito (Berberis trifoliolata), an endemic species to the Chihuahuan Desert. We identify genetic signatures based on plastid DNA and AFLP markers and perform niche modelling and spatial connectivity analyses as well as niche modelling based on records in packrats to elucidate whether orogenic events such as mountain range uplift in the Miocene or the contraction/expansion dynamics of vegetation in response to climate oscillations in the Pliocene/Pleistocene had an effect on evolutionary processes in Agarito. Our results of current niche modelling and palaeomodelling showed that the area currently occupied by Berberis trifoliolata is substantially larger than it was during the Last Interglacial period and the Last Glacial Maximum. Agarito was probably confined to small areas in the Northeastern and gradually expanded its distribution just after the Last Glacial Maximum when the weather in the Chihuahuan Desert and adjacent regions became progressively warmer and drier. The most contracted range was predicted for the Interglacial period. Populations remained in stable areas during the Last Glacial Maximum and expanded at the beginning of the Holocene. Most genetic variation occured in populations from the Sierra Madre Oriental. Two groups of haplotypes were identified: the Mexican Plateau populations and certain Northeastern populations. Haplogroups were spatially connected during the Last Glacial Maximum and separated during interglacial periods. The most important prediction of packrat middens palaeomodelling lies in the Mexican Plateau, a finding congruent with current and past niche modelling predictions for agarito and genetic results. Our results corroborate that these climate changes in the Pliocene/Pleistocene affected the evolutionary history of agarito. The journey of agarito in the Chihuahuan Desert has been dynamic, expanding and contracting its distribution

    2010-12-01

    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

    2009-12-01

    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.

  3. Determinants of healthy eating in Aboriginal peoples in Canada: the current state of knowledge and research gaps.

    Science.gov (United States)

    Willows, Noreen D

    2005-01-01

    Aboriginal peoples are the original inhabitants of Canada. These many diverse peoples have distinct languages, cultures, religious beliefs and political systems. The current dietary practices of Aboriginal peoples pose significant health risks. Interventions to improve the nutritional status of Aboriginal peoples must reflect the realities of how people make food choices and therefore should be informed by an understanding of contemporary patterns of food procurement, preparation and distribution. Most of the literature documenting the health of Aboriginal peoples is primarily epidemiologic, and there is limited discussion of the determinants that contribute to health status. The majority of studies examining dietary intake in Aboriginal communities do not aim to study the determinants of food intake per se even though many describe differences in food intake across sex, age groups, seasons and sometimes communities, and may describe factors that could have an effect on food consumption (e.g., employment status, level of education, household size, presence of a hunter/trapper/fisher, occupation, main source of income). For these reasons, there are many gaps in knowledge pertaining to the determinants of healthy eating in Aboriginal peoples that must be filled. Given the diversity of Aboriginal peoples, research to address the gaps should take place at both the national level and at a more local level. Research would be important for each of Inuit, Métis and First Nations.

    2012-05-01

    Full Text Available The Aboriginal communities in Canada are challenged by a disproportionate burden of TB infection and disease. Contact investigation (CI guidelines exist but these strategies do not take into account the unique social structure of different populations. Because of the limitations of traditional CI, new approaches are under investigation and include the use of social network analysis, geographic information systems and genomics, in addition to the widespread use of genotyping to better understand TB transmission. Guidelines for the routine use of network methods and other novel methodologies for TB CI and outbreak investigation do not exist despite the gathering evidence that these approaches can positively impact TB control efforts, even in Aboriginal communities. The feasibility and efficacy of these novel approaches to CI in Aboriginal communities requires further investigation. The successful integration of these novel methodologies will require community involvement, capacity building and ongoing support at every level. The outcome will not only be the systematic collection, analysis, and interpretation of CI data in high-burden communities to assess transmission but the prioritization of contacts who are candidates for treatment of LTBI which will break the cycle of transmission. Ultimately, the measure of success will be a clear and sustained decline in TB incidence in Aboriginal communities.

    Kruger, Estie; Perera, Irosha; Tennant, Marc

    2010-01-01

    Australians living in rural and remote areas have poorer access to dental care. This situation is attributed to workforce shortages, limited facilities and large distances to care centres. Against this backdrop, rural and remote Indigenous (Aboriginal) communities in Western Australia seem to be more disadvantaged because evidence suggests they have poorer oral health than non-Indigenous people. Hence, provision of dental care for Aboriginal populations in culturally appropriate settings in rural and remote Western Australia is an important public health issue. The aim of this research was to compare services between the Aboriginal Medical Services (AMS)-based clinics and a typical rural community clinic. A retrospective analysis of patient demographics and clinical treatment data was undertaken among patients who attended the dental clinics over a period of 6 years from 1999 to 2004. The majority of patients who received dental care at AMS dental clinics were Aboriginal (95.3%), compared with 8% at the non-AMS clinic. The rate of emergency at the non-AMS clinic was 33.5%, compared with 79.2% at the AMS clinics. The present study confirmed that more Indigenous patients were treated in AMS dental clinics and the mix of dental care provided was dominated by emergency care and oral surgery. This indicated a higher burden of oral disease and late utilisation of dental care services (more focus on tooth extraction) among rural and remote Indigenous people in Western Australia.

  10. The birthing experiences of rural Aboriginal women in context: implications for nursing.

    Science.gov (United States)

    Brown, Helen; Varcoe, Colleen; Calam, Betty

    2011-12-01

    It has been established that the birthing experiences and outcomes of rural women are shaped by poverty, isolation, limited economic opportunities, and diminishing maternity services. We lack research into how these dynamics are compounded by intersecting forms of oppression faced by Aboriginal women, to impact on their birthing experiences and outcomes. The findings of this study of rural Aboriginal maternity care in 4 communities in British Columbia show how diminishing local birthing choices and women's struggles to exert power, choice, and control are influenced by centuries of colonization. The research questions focus on rural Aboriginal women's experiences of birthing and maternity care in this neocolonial context and their desire for supportive birthing environments. A community-based participatory and ethnographic design was employed. Individual interviews, focus groups, and participant observation were the primary data sources. Although the women's experiences in each community were shaped by distinct histories and traditions, economics, politics, and geographies, the impacts of colonization and medical paternalism and the struggle for control of women's bodies during birth intersect, placing additional stress on women. The implications for nurses of accounting for the intersecting dynamics that shape Aboriginal women's experiences and birth outcomes are discussed.

  11. Knowledge Transfer and Exchange Processes for Environmental Health Issues in Canadian Aboriginal Communities

    Directory of Open Access Journals (Sweden)

    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.

    2016-04-12

    Genetic analyses, including genome-wide association studies and whole exome sequencing (WES), provide powerful tools for the analysis of complex and rare genetic diseases. To date there are no reference data for Aboriginal Australians to underpin the translation of health-based genomic research. Here we provide a catalogue of variants called after sequencing the exomes of 72 Aboriginal individuals to a depth of 20X coverage in ∼80% of the sequenced nucleotides. We determined 320,976 single nucleotide variants (SNVs) and 47,313 insertions/deletions using the Genome Analysis Toolkit. We had previously genotyped a subset of the Aboriginal individuals (70/72) using the Illumina Omni2.5 BeadChip platform and found ~99% concordance at overlapping sites, which suggests high quality genotyping. Finally, we compared our SNVs to six publicly available variant databases, such as dbSNP and the Exome Sequencing Project, and 70,115 of our SNVs did not overlap any of the single nucleotide polymorphic sites in all the databases. Our data set provides a useful reference point for genomic studies on Aboriginal Australians.

    Poor environmental conditions and poor child health in remote Australian Aboriginal communities are a symptom of a disjuncture in the cultures of a disadvantaged (and only relatively recently enfranchised) minority population and a proportionally large, wealthy dominant immigrant population, problematic social policies and the legacy of colonialism. Developing effective health promotion interventions in this environment is a challenge. Taking an ecological approach, the objective of this study was to identify the key social, economic, cultural and environmental factors that contribute to poor hygiene in remote Aboriginal communities, and to determine approaches that will improve hygiene and reduce the burden of infection among children. The methods included a mix of quantitative and qualitative community-based studies and literature reviews. Study findings showed that a combination of crowding, non-functioning health hardware and poor standards of personal and domestic hygiene underlie the high burden of infection experienced by children. Also, models of health promotion drawn from developed and developing countries can be adapted for use in remote Australian Aboriginal community contexts. High levels of disadvantage in relation to social determinants of health underlie the problem of poor environmental conditions and poor child health in remote Australian Aboriginal communities. Measures need to be taken to address the immediate problems that impact on children's health-for example, by ensuring the availability of functional and adequate water and sanitation facilities-but these interventions are unlikely to have a major effect unless the underlying issues are also addressed.

    Full Text Available Background: Poor medication management may contribute to the increased morbidity and mortality of Aboriginal people in Australia. Yet while there is extensive literature about the perceptions of healthcare providers on this issue, there is limited information on the perceptions of Aboriginal people themselves. Objectives: To investigate the perceptions of a group of Aboriginal people attending a Victorian regional Aboriginal Health Service (AHS with diagnosed medical conditions requiring medications, of their lifestyle, disease management and medication usage. Methods: Data was collected through one to one in depth interviews using a semi-structured ‘yarning’ process. Twenty patients were invited to participate in the study and were interviewed by Aboriginal Health Workers in a culturally appropriate manner. The interviews were recorded and transcribed verbatim. The data were analysed using descriptive statistics. Results: Our results show that the majority of participants perceived that changes in lifestyle factors such as diet, exercise, and smoking cessation would help improve their health. Most patients reported having been counselled on their medicines, and while the majority reported adherence and acknowledgement of the efficacy of their medicines, there was a lack of clarity regarding long term maintenance on regimens. Finally, while the majority reported taking over the counter products, some did not see the need to inform their doctor about this, or chose not to. Conclusion: Chronic illness was perceived as common in families and community. Patients relied mostly on their health care professionals as sources for their drug information. Patients may have benefited from further counselling in the area of complementary and other over the counter medicines, as well as on the necessity of maintenance of regimes for chronic disease management. Finally, lifestyle changes such as dietary improvements and smoking cessation were identified as

  11. A decolonizing approach to health promotion in Canada: the case of the Urban Aboriginal Community Kitchen Garden Project.

    Mundel, Erika; Chapman, Gwen E

    2010-06-01

    Aboriginal people in Canada suffer ill-health at much higher rates compared with the rest of the population. A key challenge is the disjuncture between the dominant biomedical approach to health in Canada and the holistic and integrative understandings of and approaches to health in many Aboriginal cultures. More fundamentally, colonization is at the root of the health challenges faced by this population. Thus, effective approaches to health promotion with Aboriginal people will require decolonizing practices. In this paper, we look at one case study of a health promotion project, the Urban Aboriginal Community Kitchen Garden Project in Vancouver, Canada, which, guided by the teachings of the Medicine Wheel, aims to provide culturally appropriate health promotion. By drawing on Aboriginal approaches to healing, acknowledging the legacy of colonization and providing a context for cultural celebration, we suggest that the project can be seen as an example of what decolonizing health promotion could look like. Further, we suggest that a decolonizing approach to health promotion has the potential to address immediate needs while simultaneously beginning to address underlying causes of Aboriginal health inequities.

    Vladislav Steljmah

    1998-10-01

    Full Text Available The paper treats the theme of aboriginal/native peoples in Post-Soviet Russia. First the authors ask: how is a people to be defined as aboriginal, or else how can such a people be distinguished from "small ethnic groups" or "ethnic minorities"? They find an answer in Convention No. 169 of the International Labour Organisation, which gives two criteria: a a social type in which pre-state forms are maintained, a more or less traditional economy and remains of collective land ownership, b a specific view of the world, sacralisation of nature, the land and its resources. According to this, 26 ethnic groups in the North and Far East of the Russian Federation can be termed aboriginal. Their total number does not surpass 9% of the population of these areas. Their present situation is marked by crisis, caused, inter alia, by the demise of former economic forms and general deculturation, unequal participation in the modern economy, demographic catastrophe, a poor health situation, aggravated by alcoholism, with also an increase of suicides and depression. The authors find the reasons for this crisis in: 1 the modernisation shock which traditional societies always suffer when coming into contact with industrial or post-industrial societies, 2 crude interference in the Soviet period into traditional modes of livings, 3 an undefined legal status and system for the protection of aboriginals and 4 years of ignoring the opinions of the latter regarding their position in the broader society. The authors identify three models of adaptation to modemisation: full adaptation, partial adaptation and no adaptation. The first is typical of individuals, but on the group level does not preserve ethnicity. The third leads to ethnic self-isolation, which is rare in Russia. The third model dominates − it entails rejection of marginalisation and a striving to be included into the broader society, but not at the expense of ethnic specificity. This was expressed by the

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

    @@ Gout is a metabolic disorder which normally undergoes 4 stages: hyperuricemia, acute gouty arthritis, an intercritical period, and final tophus. Priority associated with gout is hyperuricemia. Only 5%-10% of patients with hyperuricemia will develop gout. Indeed, the serum uric acid level is correlated with the prospects of gouty attack.1 Therefore, study of gout epidemiology should focus on the hyperuricemia of a community or ethnic population. Twenty-three million people live in Taiwan, among them, an ethnic minority of 330 000 native inhabitants (called "Aborigines"), who live mainly in high mountain areas. The rest are "ethnic Taiwanese", most of whom came from the southern Mainland Chinese provinces some 400 years ago. Some of the "ethnic Taiwanese" arrived from the central and northern areas of Mainland China 50 years ago. The languages, dietary habits and cultures of the Taiwanese and Aborigines are completely different.2

    2016-01-01

    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.

    2009-01-01

    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.

    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.

    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.

    2013-01-01

    With one of the oldest surviving cultures in the world, Australian Aboriginal people have developed immense knowledge about the diverse Australian flora. Western scientific investigation of some Australian Aboriginal medicinal plants has demonstrated interesting pharmacological activities and chemistry, however the majority of these species have not yet been extensively examined. We argue that research that is locally initiated and driven by Indigenous traditional owners in collaboration with Western scientists has significant potential to develop new plant-based products. Locally driven medicinal plants research in which traditional owners work as researchers in collaboration with University-based colleagues in the investigation of medicines rather than "stakeholders" or "informants" is one model that may be used in characterising plants with the potential to be developed into sustainable plant-based medicinal products with commercial value. Our team has taken this approach in research located both on traditional homelands and in the laboratory. Research being conducted by the University of South Australia and Chuulangun Aboriginal Corporation has led to patent filing for protection of intellectual property associated with novel compounds and extracts with the potential for development through cosmetic, complementary medicine and pharmaceutical routes. Ongoing research is examining the commercial developmental pathways and requirements for product development in these spaces. This review will address the opportunities that might exist for working in partnership with Australian Indigenous communities, some of the scientific knowledge which has been generated so far from our work together and the lessons learnt since the inception of the collaboration between the Chuulangun Aboriginal Corporation and scientists from the University of South Australia.

  3. Relationships between Psychosocial Resilience and Physical Health Status of Western Australian Urban Aboriginal Youth.

    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.

    Intestinal parasitic infections are important public health problems among underprivileged communities. This study was carried out to evaluate the infection rate of intestinal parasites among aborigine children at Pos Sungai Rual, Kelantan, Malaysia. A total of 111 faecal samples from aborigine children aged 4-12 years were screened for intestinal parasites by direct smear technique. Harada-Mori culture was also performed to identify hookworm and Strongyloides stercoralis larvae. The results showed that 87.4% of the children examined were positive for one or more parasites. Intestinal parasites were significantly lower in boys (78.7%) as compared to girls (93.8%). The infection occurred in very young children aged 4-6 years (80.0%) and the percentage of parasite-positive cases appeared to be significantly higher (92.9%) among the children aged 7-9 years. Trichuris trichiura was the most common parasite found in aborigine children (65.8%). Low socioeconomic status, poor environmental sanitation and poor personal hygiene are possible contributing factors that increase the rate of intestinal parasitic infections among the children. Thus, the parasitic diseases will continue to threaten the people's health especially among communities from rural areas if no appropriate actions are taken to diminish the transmission of the parasites.

    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.

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.

    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.

    Aboriginal Community Controlled Health Services deliver holistic and culturally appropriate primary health care to over 150 communities in Australia. Health promotion is a core function of comprehensive primary health care; however, little has been published on what enables or challenges health promotion practice in an Aboriginal Community Controlled Health Service. Apunipima Cape York Health Council (Apunipima) delivers primary health care to 11 remote north Queensland communities. The workforce includes medical, allied health, Aboriginal and Torres Strait Islander health workers and health practitioners and corporate support staff. This study aimed to identify current health promotion practices at Apunipima, and the enablers and challenges identified by the workforce, which support or hinder health promotion practice. Sixty-three staff from across this workforce completed an online survey in February 2015 (42% response rate). Key findings were: (1) health promotion is delivered across a continuum of one-on-one approaches through to population advocacy and policy change efforts; (2) the attitude towards health promotion was very positive; and (3) health promotion capacity can be enhanced at both individual and organisational levels. Workforce insights have identified areas for continued support and areas that, now identified, can be targeted to strengthen the health promotion capacity of Apunipima.

    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

  11. Aboriginal and Torres Strait Islander Worldviews and Cultural Safety Transforming Sexual Assault Service Provision for Children and Young People

    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.

    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.

    Aboriginal health policy in Australia represents a unique policy subsystem comprising a diverse network of Aboriginal-specific and "mainstream" organisations, often with competing interests. This paper describes the network structure of organisations attempting to influence national Aboriginal health policy and examines how the different subgroups within the network approached the policy discourse. Public submissions made as part of a policy development process for the National Aboriginal and Torres Strait Islander Health Plan were analysed using a novel combination of network analysis and qualitative framing analysis. Other organisational actors in the network in each submission were identified, and relationships between them determined; these were used to generate a network map depicting the ties between actors. A qualitative framing analysis was undertaken, using inductive coding of the policy discourses in the submissions. The frames were overlaid with the network map to identify the relationship between the structure of the network and the way in which organisations framed Aboriginal health problems. Aboriginal organisations were central to the network and strongly connected with each other. The network consisted of several densely connected subgroups, whose central nodes were closely connected to one another. Each subgroup deployed a particular policy frame, with a frame of "system dysfunction" also adopted by all but one subgroup. Analysis of submissions revealed that many of the stakeholders in Aboriginal health policy actors are connected to one another. These connections help to drive the policy discourse. The combination of network and framing analysis illuminates competing interests within a network, and can assist advocacy organisations to identify which network members are most influential.

    The causes of the worldwide distribution of Human T-cell Lymphotropic Virus Type 1 (HTLV-1) remain incompletely understood, with competing hypotheses regarding the number and timing of events leading to intercontinental spread on historical and prehistoric timescales. Ongoing discovery of this virus in aboriginal populations of Asia and the Americas has been the main source of evidence for the latter. We conducted molecular phylogenetic and dating analyses for 13 newly reported HTLV-1 strains from Canada. We analyzed two full-length proviral genomes from aboriginal residents of Nunavut (an autonomous territory in Northern Canada including most of the Canadian Arctic), 11 long-terminal-repeat (LTR) sequences from aboriginal residents of British Columbia's Pacific coast, and 2 LTR sequences from non-aboriginal Canadians. Phylogenetic analysis demonstrated a well-supported affinity between the two Nunavut strains and two East Asian strains, suggesting the presence of an Asian-American sublineage within the widespread "transcontinental" subgroup A clade of HTLV-1 Cosmopolitan subtype a. This putative sublineage was estimated to be 5400-11,900 years in age, consistent with a long-term presence of HTLV-1 in aboriginal populations of the Canadian Arctic. Phylogenetic affinities of the other 11 Canadian HTLV-1 aboriginal strains were diverse, strengthening earlier evidence for multiple incursions of this virus into coastal aboriginal populations of British Columbia. Our results are consistent with the hypothesis of ancient presence of HTLV-1 in aboriginal populations of North America.

    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.

    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.

  20. 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.

    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

    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.

    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

    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.

    High risk drinking is linked with high rates of physical harm. The reported incidence of alcohol - related trauma among Aboriginal and Torres Strait Islander people in the Northern Territory is the highest in the world. Facial fractures are common among young Aboriginal and Torres Strait Islanders. They are often linked with misuse of alcohol in the Northern Territory and are frequently secondary to assault. This review focuses on alcohol-related trauma in the Territory and draws attention to an urgent need for preventative health approach to address this critical issue.

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

    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.

    Full Text Available Background: Routine eye and vision assessments are vital for the detection and subsequent management of vision loss, which is particularly important for Aboriginal and Torres Strait Islander people, who face higher rates of vision loss than other Australians. In order to guide improvements, this paper will describe patterns, variations and gaps in these eye and vision assessments for Aboriginal and Torres Strait Islander people. Methods: Clinical audits from 124 primary health care centres (sample size 15,175 from five Australian States and Territories were conducted during 2005-2012. Main outcome measure was adherence to current guidelines for delivery of eye and vision assessments to adults with diabetes, those without a diagnosed major chronic disease and children attending primary health care centres. Results: Overall delivery of recommended eye and vision assessments varied widely between health centres. Of the adults with diabetes, 45% had a visual acuity assessment recorded within the previous 12 months (health centre range 0-88%, and 33% had a retinal examination recorded (health centre range 0-73%. Of the adults with no diagnosed major chronic disease, 31% had a visual acuity assessment recorded within the previous two years (health centre range 0-30%, and 13% had received an examination for trichiasis (health centre range 0-40%. In children, 49% had a record of a vision assessment (health centre range 0-97%, and 25% had a record of an examination for trachoma within the previous 12 months (health centre range 0-63%. Conclusions: There was considerable range, and variation in the recorded delivery of scheduled eye and vision assessments across health centres. Sharing the successful strategies of the better-performing health centres to support focused improvements in key areas of need may increase overall rates of eye examinations – important for the timely detection, referral and treatment of eye conditions affecting Aboriginal and

    The hepatitis B virus (HBV) genomes in Taiwanese aborigines, whose ancestors have lived in Taiwan for over 10,000 years, have not been characterized. In order to characterize of HBV in this special population, serum samples were obtained from serologically HBsAg-positive 27 Taiwanese aborigines. The pre-S1/S2 region and the full-length 3.2 kb of the HBV genome were amplified by PCR. Obtained amplicons were sequenced and confirmed the HBV genotypes by phylogenetic analysis. By phylogenetic analysis of the sequence of pre-S1/pre-S2 region, HBV/B2 (21/27: 78 %) was the most prevalent followed by genotype D (6/27: 22 %). Two strains of HBV/B2, each having 3,215 bp genomes, had recombination with genotype C in the pre-C/C gene which is characteristic of subgenotype B2 circulating in Southeast Asia. Interestingly, six strains of genotype D formed a distinct cluster between subgenotypes D1 and D2 suggesting a novel group of HBV. A similar finding could also be confirmed based on the entire 3,182 bp genome from four strains of HBV/D. This new cluster was supported by a branch with 99 % bootstrap value and 3.4-5.8 % nucleotide divergence over the entire genome from other known subgenotypes D1 to D9. Four strains of the new D subgenotype showed serotype ayw2, but had unique amino acid sequences consisting of N115 in the preS/S gene; P41 in the X gene; S239, K/E295, V567, and P708 in the P gene, respectively. From the above results, we provisionally proposed to designate it as novel quasi-subgenotype D2 identified in Taiwanese aborigines.

    In 1991, the Family Planning Association (FPA) of the Malaysian state of Perak initiated a community-based development project in the remote Aborigine village of Kampung Tisong. The community consists of approximately 34 households who survive on an average income of about US $37. Malnutrition is pervasive, even minor ailments cause death, more serious afflictions are prevalent, and the closest government clinic is 20 kilometers away and seldom used by the Aborigines. 70% of the children have access to education, but parental illiteracy is a serious educational obstacle. The goals of the FPA program are to 1) promote maternal and child health and responsible parenthood, 2) provide health education, 3) encourage women to seek self-determination, and 4) encourage the development of self-reliance in the community as a whole. The first step was to survey the community's culture, beliefs, and health status with the help of the Aborigines Department and the village headman. After a series of preliminary meetings with other agencies, the FPA began to provide activities including health talks, health courses and demonstrations, medical examinations and check-ups, and first aid training. Environmental protection and sanitation measures were included in the educational activities, and following the traditional "mutual aid system," a small plot of land was cleared for vegetable production. Vegetable gardens and needlecraft will become income-producing activities for the women. Attempts to motivate the women to use family planning have been hindered by the fact that the health of 2 women deteriorated after they began using oral contraceptives. Positive changes are occurring slowly and steadily, however, and the FPA has been instrumental in having the settlement included in a program for the hardcore poor which will provide new housing and farming projects.

    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.

    Full Text Available Abstract Background HIV infection is a serious concern in the Canadian Aboriginal population, particularly among youth; however, there is limited attention to this issue in research literature. 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

    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.

    Full Text Available This history of archaeology in Australia has been pretty well served since Mulvaney's highly influential survey of three hundred years of opinion about the nature of Australian Aboriginal people (1958. Indeed, the long-running debate about the identity of Australian archaeology, particularly about the extent to which it has developed a distinctive style, or whether its fundamental precepts and orientations remain essentially undeveloped derivations from English and North American influences, has tended to provide a ready market for research into the history of Australian archaeology.

    2016-11-01

    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.

    Fluid-dynamic and capillary forces can be used to form nearly perfect, very small spherical shells when a liquid that can solidify is passed through an annular die to form an annular jet. Gravity and certain properties of even the most ideal materials, however, can cause slight asymmetries. The primary objective of the present work is the control of this shell formation process in earth laboratories rather than space microgravity, through the development of facilities and methods that minimize the deleterious effects of gravity, aerodynamic drag, and uncontrolled cooling. The spherical shells thus produced can be used in insulation, recyclable filter materials, fire retardants, explosives, heat transport slurries, shock-absorbing armor, and solid rocket motors.

    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.

  20. The Streamlining of the Kabinakagami River Hydroelectric Project Environmental Assessment: What is the "Duty to Consult" with Other Impacted Aboriginal Communities When the Co-Proponent of the Project is an Aboriginal Community?

    Full Text Available There is existing tension within many Aboriginal communities between economic development and preservation of traditional lands for the continued practice of traditional activities. The "duty to consult" doctrine has has become an important mechanism by which these concerns were identified and addressed (when possible prior to development. This is a legal requirement that is rooted in the Constitution Act (1982 and subsequent legal case law that has further defined and outlined requirements under this obligation. This article describes the process that was carried out to advance the proposed Kabinakagami River Hydro Project Class Environmental Assessment in Northern Ontario, Canada with an emphasis on the approach to Aboriginal consultation. This project is unique because the co-proponent of the project is an Aboriginal community, with several neighbouring Aboriginal communities potentially affected by the project. This project raises questions about the approach to carrying out the duty to consult in an effective way. An evaluative framework was developed to examine timeline, information, means, and flexibility and transparency of the process to highlight shortcomings in the process and make recommendations for improvement.

    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.

  2. Aboriginal health learning in the forest and cultivated gardens: building a nutritious and sustainable food system.

    2009-01-01

    Sustainable food systems are those in which diverse foods are produced in close proximity to a market. A dynamic, adaptive knowledge base that is grounded in local culture and geography and connected to outside knowledge resources is essential for such food systems to thrive. Sustainable food systems are particularly important to remote and Aboriginal communities, where extensive transportation makes food expensive and of poorer nutritional value. The Learning Garden program was developed and run with two First Nation communities in northwestern Ontario. With this program, the team adopted a holistic and experiential model of learning to begin rebuilding a knowledge base that would support a sustainable local food system. The program involved a series of workshops held in each community and facilitated by a community-based coordinator. Topics included cultivated gardening and forest foods. Results of survey data collected from 20 Aboriginal workshop participants are presented, revealing a moderate to low level of baseline knowledge of the traditional food system, and a reliance on the mainstream food system that is supported by food values that place convenience, ease, and price above the localness or cultural connectedness of the food. Preliminary findings from qualitative data are also presented on the process of learning that occurred in the program and some of the insights we have gained that are relevant to future adaptations of this program.

  3. 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.

    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.

    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.

    2013-03-01

    The effect of school violence on mental health was examined among 12,366 Aboriginal children and adolescents, primarily First Nations, Métis, and Inuit residing off reservations in the Canadian provinces and territories. Analyses were based on the 2006 Aboriginal Peoples' Survey, a postcensal national survey of Aboriginal youth aged 6-14 years. More than one-fifth of students in the sample attended schools where violence was perceived as a problem. The occurrence of psychological or nervous disorders was about 50% higher among students exposed to school violence than among other students. School violence was a significant predictor of mental health difficulties, irrespective of socioeconomic and demographic characteristics. Virtually the entire effect was mediated by interpersonal processes, or negative quality of parent-child and peer relationships, while the effect was not explained by cultural detachment through lack of interactions with Elders and traditional language ability/use. Results underscored school violence as a significant public health concern for Aboriginal elementary and high school students, and the need for evidence-based mental health interventions for at-risk populations.

    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

    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.

    2009-08-01

    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. Researchers are accountable to both participants and the wider community for reporting their findings and for research translation so

    2012-06-01

    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

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

    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

    Introduction Tobacco smoking is a very significant behavioural risk factor for the health of Australian Aboriginal and Torres Strait Islanders, and is embedded as a social norm. With a focus on women of childbearing age, and men of similar age, this project aims to determine how Aboriginal and Torres Strait Islander smokers assess smoking risks and how these assessments contribute to their intentions to quit. The findings from this pragmatic study should contribute to developing culturally ta...

    Aboriginal and Torres Strait Islander adults in the Australian state of Victoria have a higher prevalence of psychological distress than their non-Aboriginal and Torres Strait Islander counterparts. We sought to explain this inequality, focussing on the social determinants of health. We used population-based survey data from the 2008 Victorian Population Health Survey; a cross-sectional landline computer-assisted telephone survey of 34,168 randomly selected adults. We defined psychological distress as a score of 22 or more on the Kessler 10 Psychological Distress scale. We used logistic regression to identify socio-demographic characteristics and social capital indicators that were associated with psychological distress. We then created multivariable models to explore the association between psychological distress and Aboriginal and Torres Strait Islander status that incorporated all significant socioeconomic status (SES) and social capital variables, adjusting for all non-SES socio-demographic characteristics. Aboriginal and Torres Strait Islander Victorians (24.5%) were more than twice as likely than their non-Aboriginal and Torres Strait Islander counterparts (11.3%) to have psychological distress (odds ratio (OR) = 2.56, 95% confidence interval; 1.67-3.93). Controlling for SES, negative perceptions of the residential neighbourhood, lack of social support from family, social and civic distrust, and all non-SES socio-demographic variables (age, sex, marital status, household composition, and rurality), rendered the previously statistically significant inequality in the prevalence of psychological distress, between Aboriginal and Torres Strait Islander Victorians and their non-Aboriginal and Torres Strait Islander counterparts, insignificant at the p = 0.05 level (OR = 1.50; 0.97-2.32). Psychological distress is an important health risk factor for Aboriginal and Torres Strait Islander adults that has yet to be widely acknowledged and addressed. Addressing the

    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.

  5. 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.

  6. The Durkheim-Tarde debate and the social study of aboriginal youth suicide.

    Science.gov (United States)

    Niezen, Ronald

    2015-02-01

    A debate that took place in France in the early 20th century still has much to tell us about the interpretation and strategies of intervention of suicide, particularly the "cohort effect" of aboriginal youth suicide. The act of suicide, for Durkheim, was inseparable from the problem of social cohesion, with extremes in solidarity and regulation predictably reflected in high rates of suicide. For Gabriel Tarde, by contrast, suicide was seen as an outcome of changeable ideas found in processes of innovation and imitation among creatively receptive individuals. This latter approach remains overlooked in favor of a growing reliance on conceptions of historical trauma and conditions of social disintegration. Recognizing the idea of suicide itself as a potential locus of solidarity opens up other possibilities for responding to and intervening in suicide crises or "clusters."

  7. Mutual Incomprehension: The Cross Cultural Domain of Work in a Remote Australian Aboriginal Community

    Directory of Open Access Journals (Sweden)

    Rolf Gerritsen

    2010-07-01

    Full Text Available This article is set within the context of concerns about Indigenous workforce participation disadvantage. It discusses conflicting life-worlds relating to work of both Aboriginal and non- Indigenous residents in Ngukurr, a remote community in South East Arnhem Land in Australia’s Northern Territory. It contrasts an Indigenous social culture of kinship and relatedness to a Western one where employment is central to identity and its formal rules shape behaviour. We investigate how these different social ideologies affect cross-cultural relationships and shape the formal employment domain in Ngukurr. Given that governments have moved to more assimilationist policies in recent years, there are important policy implications following from this mutual cultural incomprehension.

    Liu, Tzu-Ming; Lu, Dau-Jye

    2014-01-01

    We show that tourism activities severely impact the ecology of Orchid Island, its natural resources, and the culture of the Tao tribe. For example, highway widening, in response to the increased traffic volumes caused by tourism, required many Pandanus trees to be cut and removed, which has placed the coconut crabs in danger of extinction. To promote eco-tourism, observation trips to observe Elegant Scops owls and Birdwing butterflies have taken place, which has affected the breeding of these two protected species. The Elegant Scops owls- and Birdwing butterflies-related tourism activities also break the "evil spirits" taboo of the Tao people and have caused the disappearance of the specifications for using traditional natural resources, causing natural ecosystems to face the threat of excessive use. In addition to promoting and advocating aboriginal tourism of the Tao people on Orchid Island, the Taiwanese government should help the Tao people to develop a management model that combines traditional regulations and tourism activities.

  10. The Importance of Insects in Australian Aboriginal Society: A Dictionary Survey

    Directory of Open Access Journals (Sweden)

    2015-09-01

    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.

    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.

    Helin, C. [Native Investment and Trade Association, Richmond, BC (Canada)

    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.

  13. Aboriginal new world epidemiolgy and medical care, and the impact of Old World disease imports.

    Science.gov (United States)

    Newman, M T

    1976-11-01

    Various workers, including T. D. Stewart, claim that the aboriginal Americas were relatively disease-free because of the bering Strait cold-screen, eliminating many pathogens, and the paucity of zoonotic infections because of few domestic animals. Evidence of varying validity suggests that precontact Americns had their own strains of treponemic infections, bacillary and amoebic dysenteries, influenza and viral penumonia and other respiratory diseases, salmonellosis and perhaps other food poisoning, various arthritides, some endoparasites such as the ascarids, and several geographically circumscribed diseases such as the rickettsial verruca (Carrion's disease) and New World leishmaniasis and trypanosomiasis. Questionably aboriginal are tuberculosis and typhus. Accordingly, virtually all the "crowd-type" ecopathogenic diseases such as smallpox, yellow fever, typhoid, malaria, measles, pertussis, polio, etc., appear to have been absent from the New World, and were only brought in by White conquerors and their Black slaves. My hypothesis is that native American medical care systems--especially in the more culturally advanced areas--were sufficiently sophisticated to deal with native disease entities with reasonable competence. But native medical systems could not cope with the "crowd-type" disease imports that struck Indian and Eskimos as "virgin-field" populations. Reanalysis of native population losses through a genocidal combination of diease, war, slavery and attendant cultural disruption by Dobyns, Cook and others strongly suggest that traditiona estimates underplayed the death toll by a factor of the general order of ten. This would make for an immediately pre-contact Indian population of some 90-111 million instead of the tradition 8-11 million. Evidence is growing that Indians may have been no more susceptible to new pathogens that are other "virgin soil" populations, and thus their immune systems need not be considered less effective than those in other people

  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

  15. Optimisation modelling to assess cost of dietary improvement in remote Aboriginal Australia.

    Directory of Open Access Journals (Sweden)

    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 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.

    2012-11-01

    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.

    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.

    Tsunoda, Naofumi; Hjorth-Jensen, Morten; Otsuka, Takaharu

    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...

    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.

  4. The Touch Pad Body: A Generative Transcultural Digital Device Interrupting Received Ideas and Practices in Aboriginal Health

    2014-05-01

    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.

  5. The role of traditional medicine practice in primary health care within Aboriginal Australia: a review of the literature.

    Science.gov (United States)

    Oliver, Stefanie J

    2013-07-02

    The practice of traditional Aboriginal medicine within Australia is at risk of being lost due to the impact of colonisation. Displacement of people from traditional lands as well as changes in family structures affecting passing on of cultural knowledge are two major examples of this impact. Prior to colonisation traditional forms of healing, such as the use of traditional healers, healing songs and bush medicines were the only source of primary health care. It is unclear to what extent traditional medical practice remains in Australia in 2013 within the primary health care setting, and how this practice sits alongside the current biomedical health care model. An extensive literature search was performed from a wide range of literature sources in attempt to identify and examine both qualitatively and quantitatively traditional medicine practices within Aboriginal Australia today. Whilst there is a lack of academic literature and research on this subject the literature found suggests that traditional medicine practice in Aboriginal Australia still remains and the extent to which it is practiced varies widely amongst communities across Australia. This variation was found to depend on association with culture and beliefs about disease causation, type of illness presenting, success of biomedical treatment, and accessibility to traditional healers and bush medicines. Traditional medicine practices were found to be used sequentially, compartmentally and concurrently with biomedical healthcare. Understanding more clearly the role of traditional medicine practice, as well as looking to improve and support integrative and governance models for traditional medicine practice, could have a positive impact on primary health care outcomes for Aboriginal Australia.

The central idea of this proposal is to take the advantages of two existing models, the Projected Shell Model (PSM) and the Fermion Dynamical Symmetry Model (FDSM), to construct a multi-shell shell model. The PSM is an efficient method of coupling quasi-particle excitations to the high-spin rotational motion, whereas the FDSM contains a successful truncation scheme for the low-spin collective modes from the spherical to the well-deformed region. The new shell model is expected to describe simultaneously the single-particle and the low-lying collective excitations of all known types, yet keeping the model space tractable even for the heaviest nuclear systems.

    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.

    Full Text Available 2007 marked the 40th anniversary of the 1967 Referendum. Back on May 27th 1967, more than 90% of Australian eligible voters said “yes’ to two changes of the Australian Constitution considered discriminatory to Aboriginal people. 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.

    Mainstream mental health services in Australia have failed to provide culturally appropriate care for Aboriginal and Torres Strait Islander people despite several national reports and policies that have attempted to promote positive service development in response to the calls for change from the Aboriginal and Torres Strait Islander communities. In light of this situation, this article considers the ideas of Frantz Fanon and their potential for promoting cultural safety (Ramsden, 2002) in mainstream mental health services. This article argues that Fanon's ideas provide a conceptual strategy for nurses that prompts reflection and establishes a critical theoretical perspective linking power imbalance and inequitable social relationships in health care, thus complementing the aims of cultural safety. The purpose of this critical reflection is to guide nurses' understanding of the relationship between colonization and health status in order to change their attitudes from those that continue to support current hegemonic practices and systems of health care to those that support the health of Aboriginal and Torres Strait Islander people.

    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.

    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 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.

    2009-04-01

    The main components of Mollusc shells are carbonate minerals: calcite and aragonite. ACC is present in larval stages. Calcite and aragonite can be secreted simultaneously by the mantle. Despite the small number of varieties, the arrangement of the mineral components is diverse, and dependant upon the taxonomy. They are also associated with organic components much more diverse, the diversity of which reflects the large taxonomic diversity. From TGA analyses, the organic content (water included) is high (>5% in some layers). The biomineralisation process is not a passive precipitation process, but is strongly controlled by the organism. The biological-genetic control is shown by the constancy of the arrangement of the layers, the mineralogy and the microstructure in a given species. Microstructural units (i.e. tablets, prisms etc.) have shapes that do not occur in non-biogenic counterparts. Nacreous tablets, for example, are flattened on their crystallographic c axis, which is normally the axis of maximum growth rate for non-biogenic aragonite. Morever, their inner structure is species-specific: the arrangements of nacreous tablets in Gastropoda - Cephalopoda, and in Bivalvia differ, and the inner arrangement of the nacreous tablets is different in ectocochlear and endocochlear Cephalopoda. The organic-mineral ratios also differ in the various layers of a shell. Differences in chemical composition also demonstrates the biological-genetic control: for example, aragonite has a low Sr content unknown in non-biogenic samples; two aragonitic layers in a shell have different Sr and Mg contents, S is higher in calcitic layers. Decalcification releases soluble (SOM) and insoluble (IOM) organic components. Insoluble components form the main part of the intercrystalline membranes, and contain proteins, polysaccharides and lipids. Soluble phases are present within the crystals and the intercrystalline membranes. These phases are composed of more or less glycosylated proteins

    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

    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

    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

    Full Text Available Abstract Background Obesity and related cardiovascular and metabolic conditions are well recognized problems for Australian Aboriginal and Torres Strait Islander peoples. However, there is a dearth of research on relevant eating disorders (EDs such as binge eating disorder in these groups. Methods Data were obtained from interviews of 3047 (in 2005 and 3034 (in 2008 adults who were participants in a randomly selected South Australian household survey of individuals' age > 15 years. The interviewed comprised a general health survey in which ED questions were embedded. Data were weighted according to national census results and comprised key features of ED symptoms. Results In 2005 there were 94 (85 weighted First Australian respondents, and in 2008 65 (70 weighted. Controlling for secular differences, in 2005 rates of objective binge eating and levels of weight and shape influence on self-evaluation were significantly higher in indigenous compared to non-indigenous participants, but no significant differences were found in ED features in 2008. Conclusions Whilst results on small numbers must be interpreted with caution, the main finding was consistent over the two samples. For First Australians ED symptoms are at least as frequent as for non-indigenous Australians.

    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.

Main outcomes were serological titers pre and post treatment, diabetic status, and duration of follow up.Treatment success was achieved in 62% to 79% of cases dependent on the methods employed for the diagnosis of infection and assessment of treatment outcome. Type 2 Diabetes Mellitus (T2DM was found to be significantly associated with treatment failure in this group for two of the three methods employed.Ivermectin has been confirmed as an effective treatment for S stercoralis infection in this setting. T2DM appears to be an independent risk factor for treatment failure in this population, and plausible mechanisms to explain this observation are presented.

    This manuscript presents the first non-destructive synchrotron micro-X-ray fluorescence study of natural mineral pigments on Aboriginal Australian objects. Our results demonstrate the advantage of XFM (X-ray fluorescence microscopy) of Aboriginal Australian objects for optimum sensitivity, elemental analysis, micron-resolution mapping of pigment areas and the method also has the advantage of being non-destructive to the cultural heritage objects. Estimates of pigment thickness can be calculated. In addition, based on the elemental maps of the pigments, further conclusions can be drawn on the composition and mixtures and uses of natural mineral pigments and whether the objects were made using traditional or modern methods and materials. This manuscript highlights the results of this first application of XFM to investigate complex mineral pigments used on Aboriginal Australian objects.

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.

    This paper explores the relationship between place and health inequity as experienced by Aboriginal youth living in Winnipeg, Canada. Between 2010 and 2011, a team of youth (N = 8) associated with a community-based Aboriginal youth arts program undertook a participatory community mapping process in order to link their personal health geographies to their right to the city. The results demonstrated several ways in which place, mobility, and boundaries affected their health experiences and, in turn, reflected their perceptions of health inequity. The study confirms that urban spaces can produce, and are produced by, highly racialized geographies that work to socially isolate, segregate, and immobilize Aboriginal youth while concomitantly increasing their exposure to higher risks to their health and well being.

    The per capita alcohol consumption of the Northern Territory, Australia, is second highest in the world, estimated 15.1 liters of pure alcohol per year. Alcohol abuse is a major public health concern among Aboriginal and Torres Strait Islander people in Australia. The Aboriginal and Torres Strait Islanders in the Northern Territory consume approximately 16.9 liters of pure alcohol per year. This descriptive review is based on current published and grey literature in the context of high risk alcohol use, with a special focus on the epidemiological, etiological, and social factors, to predict alcohol misuse among the Australian Aboriginal and Torres Strait Islanders in Northern Territory. The methodology involved a descriptive search on PubMed, Northern Territory government reports, health databases, and Web sites with an emphasis on the etiology and epidemiology of high-risk alcohol consumption among the Australian Aboriginal and Torres Strait Islanders of the Northern Territory. This review has its own limitations because it does not rely on systematic review methodologies. However, it presents real data on the motives for binge drinking and alcohol-related violent assaults of this vulnerable population. Alcohol abuse and alcohol-related harms are considerably high among the rural and remote communities where additional research is needed. High-risk alcohol misuse within Australian Aboriginal and Torres Strait Islanders communities often leads to a series of physical and social consequences. This review highlights the need for culturally appropriate intervention approaches focusing on alcohol misuse among the Aboriginal and Torres Strait Islanders population of the Northern Territory.

    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.

    We construct a rotating thin-shell wormhole using a Myers-Perry black hole in five dimensions, using the Darmois-Israel junction conditions. The stability of the wormhole is analyzed under perturbations. We find that exotic matter is required at the throat of the wormhole to keep it stable. Our analysis shows that stability of the rotating thin-shell wormhole is possible if suitable parameter values are chosen.

    We present a study of the inner (out to $\\sim$1 R$_{\\mathrm{eff}}$) stellar populations of 9 shell galaxies. We derive stellar population parameters from long slit spectra by both analyzing the Lick indices of the galaxies and by fitting Single Stellar Population model spectra to the full galaxy spectra. The results from the two methods agree reasonably well. Many of the shell galaxies in our sample appear to have lower central $\\mathrm{Mg}_{2}$ index values than non-shell galaxies of the same central velocity dispersion, which is likely due to a past interaction event. Our shell galaxy sample shows a relation between central metallicity and velocity dispersion that is consistent with previous samples of non-shell galaxies. Analyzing the metallicity gradients in our sample, we find an average metallicity gradient of -0.16$\\pm$0.10 dex per decade in radius. We compare this with formation models to constrain the merging history of shell galaxies. We argue that our galaxies likely have undergone major mergers in...

    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 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

    Full Text Available Abstract Background The global rise of Type 2 diabetes and its complications has drawn attention to the burden of non-communicable diseases on populations undergoing epidemiological transition. The life course approach of a birth cohort has the potential to increase our understanding of the development of these chronic diseases. In 1987 we sought to establish an Australian Indigenous birth cohort to be used as a resource for descriptive and analytical studies with particular attention on non-communicable diseases. The focus of this report is the methodology of recruiting and following-up an Aboriginal birth cohort of mobile subjects belonging to diverse cultural and language groups living in a large sparsely populated area in the Top End of the Northern Territory of Australia. Methods A prospective longitudinal study of Aboriginal singletons born at the Royal Darwin Hospital 1987–1990, with second wave cross-sectional follow-up examination of subjects 1998–2001 in over 70 different locations. A multiphase protocol was used to locate and collect data on 686 subjects with different approaches for urban and rural children. Manual chart audits, faxes to remote communities, death registries and a full time subject locator with past experience of Aboriginal communities were all used. Discussion The successful recruitment of 686 Indigenous subjects followed up 14 years later with vital status determined for 95% of subjects and examination of 86% shows an Indigenous birth cohort can be established in an environment with geographic, cultural and climatic challenges. The high rates of recruitment and follow up indicate there were effective strategies of follow-up in a supportive population.

    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.

    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

    Despite a widespread global distribution and highly variable disease phenotype, there is little DNA sequence diversity among isolates of Mycobacterium tuberculosis. In addition, many regional population genetic surveys have revealed a stereotypical structure in which a single clone, lineage, or clade makes up the majority of the population. It is often assumed that dominant clones are highly adapted, that is, the overall structure of M. tuberculosis populations is the result of positive selection. In order to test this assumption, we analyzed genetic data from extant populations of bacteria circulating in Aboriginal communities in Saskatchewan, Canada. Demographic parameters of the bacterial population were estimated from archival epidemiological data collected over approximately 130 years since the onset of epidemic tuberculosis in the host communities. Bacterial genetic data were tested against neutral theory expectations and the local evolutionary history of M. tuberculosis investigated by phylogenetic analysis. Our findings are not consistent with positive selection on the bacterial population. Instead, we uncovered founder effects persisting over decades and barriers to gene flow within the bacterial population. Simulation experiments suggested that a combination of these neutral influences could result in the stereotypical structure of M. tuberculosis populations. Some aspects of population structure were suggestive of background selection, and data were on the whole consistent with combined effects of population bottlenecks, subdivision, and background selection. Neutral phenomena, namely, bottlenecks and partitions within populations, are prominent influences on the evolution of M. tuberculosis and likely contribute to restricted genetic diversity observed within this species. Given these influences, a complex evolutionary model will be required to define the relative fitness of different M. tuberculosis lineages and, ultimately, to uncover the genetic

    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.

    This investigation studied the dental health status of a group of 184 Australian Aboriginal children with a mean age of 4.4 +/- 0.8 years, who were attending pre-schools in metropolitan Brisbane, a non-fluoridated state capital city. The DDE (Developmental Defects of Enamel) Index was used to chart enamel hypoplasia and enamel opacities. WHO criteria was used to diagnose dental caries. The results showed that 98% of children had at least one tooth showing developmental enamel defects. Each child had a mean of 3.8 +/- 1.7 teeth affected by enamel hypoplasia and another 1.1 +/- 0.8 teeth affected by enamel opacity. Seventy-eight percent of the children had dental caries. The mean number of decayed, missing, filled teeth (dmft) per child was 3.8 +/- 3.7. The decayed component constituted 3.5 (95%) of the mean dmft, indicating a high unmet restorative need in this group. The mean dmfs (decayed, missing, filled, surfaces) was 5.9 +/- 7.3. Maxillary anterior labial decay of at least one tooth affected 43 (23%) of the children. In this sub-group, the dmft and dmfs was 9.1 +/- 2.8 and 15.4 +/- 7.7 respectively. Oral debris was found in 98% of the children. It is hypothesized that the high levels of underlying developmental enamel defects, compounded by low fluoride exposure, poor oral hygiene and a diet high in refined sugars pose an important caries risk factor in this group of children.

    Full Text Available Objectives: High-risk types of human papillomavirus (HPV are strongly associated with cervical cancer (CC, and Chlamydia trachomatis (CT, the most frequent sexually transmitted bacterial infection (STBI worldwide, seems to be a risk factor for HPV infection and for CC. It is also known that both agents are more prevalent in vulnerable communities where lack of adequate primary health care is a cause for concern. The aim of this work was to determine the impact of CT and HPV infections in women belonging to an isolated aboriginal population (Pilaga community from a poor region in Northern Argentina (province of Formosa. For this purpose, a cross-sectional study was performed in all sexually active Pilaga women, who attended a local community-based gynecological health screening project. The polymerase chain reaction (PCR method on a cervical brush specimen was used to detect both agents. Results: A total of 227 women (20% of the total female population of the Pilaga community were studied and the overall prevalence was 26.4% for CT, 46.7% for HPV and 16.3% for concurrent infection. CT infection was higher in HPV DNA positive (34.2% than in HPV DNA negative women (19%; OR: 2.22/95% CI = 1.16-4.28 / p = 0.009 and the most prevalent HPV types were HPV-16 (19.4%, 6 and 18 (5.3%, 58 (3.5% and 33 (3.1%. Conclusions: The prevalence of CT and HPV observed in Pilaga women are among the worst registered in Latin America. Also, data collected suggest that chlamydial infection may play an important role in the natural history of HPV infection. On this respect, we propose that the association between these two agents seems to be more related to a mutual potentiation than to the fact that they share a common route of transmission.

    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.

    Chronic inflammation contributes to multiple ageing-related musculoskeletal and neurodegenerative diseases, cardiovascular diseases, asthma, rheumatoid arthritis, and inflammatory bowel disease. More recently, chronic neuroinflammation has been attributed to Parkinson's and Alzheimer's disease and autism-spectrum and obsessive-compulsive disorders. To date, pharmacotherapy of inflammatory conditions is based mainly on nonsteroidal anti-inflammatory drugs which in contrast to cytokine-suppressive anti-inflammatory drugs do not influence the production of cytokines such as tumour necrosis factor-α or nitric oxide. However, their prolonged use can cause gastrointestinal toxicity and promote adverse events such as high blood pressure, congestive heart failure, and thrombosis. Hence, there is a critical need to develop novel and safer nonsteroidal anti-inflammatory drugs possessing alternate mechanism of action. In this study, plants used by the Dharawal Aboriginal people in Australia for the treatment of inflammatory conditions, for example, asthma, arthritis, rheumatism, fever, oedema, eye inflammation, and inflammation of bladder and related inflammatory diseases, were evaluated for their anti-inflammatory activity in vitro. Ethanolic extracts from 17 Eucalyptus spp. (Myrtaceae) were assessed for their capacity to inhibit nitric oxide and tumor necrosis factor-α production in RAW 264.7 macrophages. Eucalyptus benthamii showed the most potent nitric oxide inhibitory effect (IC50  5.57 ± 1.4 µg/mL), whilst E. bosistoana, E. botryoides, E. saligna, E. smithii, E. umbra, and E. viminalis exhibited nitric oxide inhibition values between 7.58 and 19.77 µg/mL.

    This study was conducted to determine the prevalence of intestinal parasites among children and adult Orang Aslis (Aborigines) from different locations in Perak. Faecal samples were collected and analyzed using the direct smear and formal ether sedimentation technique. Some of the faecal samples were stained using the Modified Acid fast stain for Cryptosporidium. Nail clippings of the respondents and the soil around their habitat were also analyzed. Of the 77 stool samples examined, 39 (50.6%) were positive for at least one intestinal parasite. The most common parasite detected was Trichuris trichiura (39.0%) followed by Ascaris lumbricoides (26.9%), Entamoeba coli (5.2%), Giardia lamblia (5.2%), Blastocystis hominis (3.9%), hookworm (3.9%), Entamoeba histolytica (1.3%), Iodamoeba butschlii (1.3%) and Cryptosporidium sp. (1.3%) respectively. Some respondents had single parasites (24.7%), some with two parasites (18.2%). Some with three parasites (6.5%) and one had four parasites species (1.3%). The parasites were slightly more common in females (54.7%) than males ((41.7%). The parasites were more common in the 13-20 year age group (90.9%) followed by 1-12 years (69.6%), 21-40 year age group (34.8%) and least in the 41-60 year age group (27.8%). Nail examinations of the respondents did not show any evidence of parasites. One had a mite, three had pollen grains and one had yeast cells isolated from the finger nails. Soil samples taken around their houses showed only one sample with a nematode ova and one with oocyst which was of a non human origin.

    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.

    2016-01-01

    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.

    Different methods of calculation of quantum corrections to the thermodynamical characteristics of a black hole are discussed and compared. The relation between on-shell and off-shell approaches is established. The off-shell methods are used to explicitly demonstrate that the thermodynamical entropy S^{TD} of a black hole, defined by the first thermodynamical law, differs from the statistical-mechanical entropy S^{SM}, determined as S^{SM}=-\\mbox{Tr}(\\hat{\\rho}^H\\ln\\hat{\\rho}^H) for the density matrix \\hat{\\rho}^H of a black hole. It is shown that the observable thermodynamical black hole entropy can be presented in the form S^{TD}=\\pi {\\bar r}_+^2+S^{SM}-S^{SM}_{Rindler}. Here {\\bar r}_+ is the radius of the horizon shifted because of the quantum backreaction effect, and S^{SM}_{Rindler} is the statistical-mechanical entropy calculated in the Rindler space.

    2012-01-01

    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 nontrivial fixed point, with a value of the cosmological constant that is independent of the gauge-fixing parameters.

    Full Text Available This paper datails the design and implementation of an AI-based diagnostic shell. The shell has a user-interface which takes in the complaint and aids the user throughout the consultation. The 'expert knowledge' is acquired and encoded in the form of 'IF-THEN' rules, The control mechanism routes through the rules chaining first backwards to identify a fault and then forwards to confirm it.Explanation facilities have been provided to enable the user query the reason for any question asked, a facility to go back and re-answer any previous question, and a trace and explanation of the path of reasoning.This shell was developed and first used for the diagnosis of a digital exchange. It was then applied for the fault-finding of the moving target indicator used in the radar.

  18. 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...

    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.

MEASURE AND ANALYSIS . A measure of perceived primary ownership subjected to linear trend analysis. RESULTS. KSDPP staff were perceived as primary owner at T1 and shared ownership with Community Advisory Board (CAB) members at T2 and T3. Trend tests indicated greater perceived ownership between T1 and T3 for CAB (χ(2)(1)  =  12.3, p community driven from the beginning. It was not dependent on an external academic change agent to activate the community and develop the community's capacity to plan and implement a solution. It still took several years for the grassroots CAB to take responsibility from KSDPP staff, thus indicating the need for sustained funding to build grassroots community capacity.

  1. Potential seasonal ecological challenge of heat strain among Australian Aboriginal people practicing traditional subsistence methods: a computer simulation.

    Ulijaszek, S J

    2001-11-01

    It has been largely accepted that Australian Aboriginal people practicing hunting and gathering traditionally underused their objective economic possibilities by working short hours relative to nonhunter-gatherer populations. However, the possibility that their subsistence quest might have been limited by potential heat strain has not been considered for Australian hunter-gatherers. In this article the influence of work and heat load on the potential for heat strain among adult male Australian Aboriginal people is modelled. The possibility that the short working day of Arnhem Land adults reported in the literature might reflect ecologically limited work scheduling by way of potential heat strain is examined. Three climatic regions of the North of Western Australia and the Northern Territory were identified, using data available from the Australian Bureau of Meteorology. Data from the months of January, April, July, and October were used with the United States Army Heat Strain Model, along with assumptions with respect to work load and time scheduling. Predictive modelling indicates that a late start to the working day could carry considerable risks of potential heat strain during the summer, when humidity and maximum daily temperature are highest for all three climatic regions, but especially in the tropical coastal region. While extended work times may have been needed to acquire adequate food under traditional conditions, work output could have been limited by potential heat strain under some conditions likely to have prevailed.

    1998-01-01

    The discovery of chronic renal failure in a child, and the meaning of this experience from the perspective of the child's family caregivers have previously not been described in the literature on aboriginal health. During the summer of 1995, a phenomenological approach was used to explore this phenomena with 10 urban aboriginal family caregivers. These caregivers were providing care for their children who were receiving health care services at the outpatient children's clinic or the transplant unit at one urban tertiary care hospital. The findings of this research have helped create the beginning of a nursing data base of knowledge about aboriginal family caregivers of children who have chronic renal failure. In this paper, three of the main themes: surviving; relocation; enhancing power; and five sub-themes: providing nutrition; getting involved; educating the caregivers; educating the community; and returning to traditional ways are described. Implications of the findings for health care providers of children who have renal failure and their family caregivers are discussed. Issues that need to be addressed to help meet the needs of aboriginal family caregivers are identified. These issues include communication strategies, culturally appropriate teaching methods, access to resources, and community development initiatives.

    The conductive shell in reversed field pinch devices plays an important role in controlling plasma and in suppressing MHD instabilities. The shell in the Keda torus experiment reversed field pinch (KTX-RFP) device includes a 6-mm stainless steel vacuum chamber and a 1.5-mm stabilizing copper shell. This stabilizing shell has both poloidal and toroidal gaps to allow a coupling of electromagnetic energy to the plasma. Nevertheless, any gaps in this shell generate error fields. A 3D electromagnetic field model has been used to study effects of the gap on the shell. Using off-center current filaments instead of the distributed plasma current density, numerical analyses render the induced current distribution on the stabilizing shell and the resultant error field distribution at a specific frequency. From the analyses and comparisons of different configurations for the stabilizing shell, a suitable shell design is chosen consisting of three sections: one primary shell, two poloidal shield shells, and two toroidal shield shells. Moreover, the time evolution of the magnetic field inside and outside the stabilizing shell was obtained for this design and the dependence of the magnetic field penetration time on mode number and location has been investigated.

  10. Validity and Acceptability of Kimberley Mum’s Mood Scale to Screen for Perinatal Anxiety and Depression in Remote Aboriginal Health Care Settings

    2017-01-01

    Background The Edinburgh Postnatal Depression Scale (EPDS) is widely recommended for perinatal anxiety and depression screening. However, many Aboriginal women find EPDS language complex and confusing, and providers find using it with Aboriginal women challenging. The two part Kimberley Mum’s Mood Scale (KMMS) was developed to improve screening: Part 1 is a Kimberley version of EPDS; Part 2 is a psychosocial tool that enables contextualisation of Part 1 scores. We aimed to determine if KMMS is a valid and acceptable method of identifying Kimberley Aboriginal perinatal women at risk of anxiety or depressive disorders compared to a semi-structured clinical interview. Methods Across 15 sites in the Kimberley, Western Australia, 97 Aboriginal women aged 16 years and older who intended to continue with their pregnancy or had a baby within the previous 12 months were administered the KMMS by trained healthcare providers who provided an overall assessment of no, low, moderate or high risk; 91 participants were then independently assessed by a blinded clinical expert using Diagnostic and Statistical Manual of Mental Disorders, 4th Edition criteria. A qualitative approach was used to determine KMMS’ acceptability. Results Part 1 had high internal consistency (Cronbach’s alpha, 0.89), and overall KMMS risk equivalence for screening for anxiety or depressive disorders was moderate (sensitivity, 83%; specificity, 87%; positive predictive value, 68%). Participants found the process easy and useful, and healthcare providers found KMMS more useful than EPDS. Part 2 allowed healthcare providers to ask questions that gave participants an opportunity to express themselves, resulting in a deeper understanding between them. Conclusion KMMS is an effective tool for identifying Kimberley Aboriginal perinatal women at risk of anxiety and depressive disorders. Adoption of KMMS with culturally safe training and support is likely to improve screening processes, and with further

  12. 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...

    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.

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.

    Full Text Available BACKGROUND: Invasive pneumococcal disease (IPD continues to occur at high rates among Australian Aboriginal people. The seven-valent pneumococcal conjugate vaccine (7vPCV was given in a 2-4-6-month schedule from 2001, with a 23-valent pneumococcal polysaccharide vaccine (23vPPV booster at 18 months, and replaced with 13vPCV in July 2011. Since carriage surveillance can supplement IPD surveillance, we have monitored pneumococcal carriage in western Australia (WA since 2008 to assess the impact of the 10-year 7vPCV program. 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

    This book focuses on the free vibrations of graphite-epoxy laminated composite stiffened shells with cutout both in terms of the natural frequencies and mode shapes. The dynamic analysis of shell structures, which may have complex geometry and arbitrary loading and boundary conditions, is solved efficiently by the finite element method, even including cutouts in shells. The results may be readily used by practicing engineers dealing with stiffened composite shells with cutouts. Several shell forms viz. cylindrical shell, hypar shell, conoidal shell, spherical shell, saddle shell, hyperbolic paraboloidal shell and elliptic paraboloidal shell are considered in the book. The dynamic characteristics of stiffened composite shells with cutout are described in terms of the natural frequency and mode shapes. The size of the cutouts and their positions with respect to the shell centre are varied for different edge constraints of cross-ply and angle-ply laminated composite shells. The effects of these parametric variat...

    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.

    2016-01-01

    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.

  11. Indentation of Ellipsoidal and Cylindrical Elastic Shells

    2012-10-01

    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.

    The incidence of aplastic anemia is reported to be higher in Asia than elsewhere. We studied the frequency of human leukocyte antigen (HLA) DRB1 alleles in aplastic anemia patients from 2 genetically similar aboriginal groups, the Kadazan and the Dusun, and compared them with genetically matched community and hospital controls. HLA-DRB1*15 was significantly higher in the patients compared with controls (p = 0.005), confirming similar findings in Japanese and Caucasian studies. Further testing indicated a significantly higher frequency of HLA-DRB1*1501 in patients compared with controls (p = 0.0004) but no significant difference in the frequency of HLA-DRB1*1502. The high frequency of HLA-DRB1*15 in the Kadazan and Dusun population combined with the wide variety of environmental factors associated with aplastic anemia could be the reason for the elevated incidence of aplastic anemia in the Kadazan and Dusun in Sabah.

    Aboriginal Economic Renewal Initiative (AERI) has the mandate to develop partnerships and identify both barriers and solutions as they relate to sustainable economic development. This forum provided an opportunity for First Nation economic developers, representatives from government and other organizations in Ontario to develop business relationships beneficial to all parties. The participants discussed a wide range of topics, such as the creation of partnerships in the resource sector, the politics of resource development, and business models and funding agents. At the end of the forum, two trends were identified. Mainstream economic stakeholders are recognizing the increased strength of First Nations in major decision making regarding the development of resources in Canada. Future relationships between First Nations and the economic mainstream will determine in large part the landscape for resource development in Canada. tabs., figs.

  15. Moving the body painting into the art gallery — knowing about and appreciating works of Aboriginal art

    Howard Morphy

    2011-06-01

    Full Text Available The paper focuses on two kinds of relationship: between Western fine art and Indigenous art, and between anthropological and art historical approaches to understanding and appreciating works of art. The primary focus is on the process by which Australian Aboriginal art came to be incorporated within galleries of fine art. This process brought both kinds of relationships to the fore in the contemporary context and challenged established boundaries exemplified by the distinction between the museum and the art gallery. It is argued that objects encompassed within the category of fine art come from very different cultural traditions and historical backgrounds. The methods of both art history and anthropology can be productively applied in analysing the forms and significance of artworks in their social and cultural contexts. The paper concludes by considering some of the implications of the co-presence of artworks from different cultural traditions in the same contemporary gallery spaces.

  16. Shell Evolutions and Nuclear Forces

    2014-01-01

    During the last 30 years, and more specifically during the last 10 years, many experiments have been carried out worldwide using different techniques to study the shell evolution of nuclei far from stability. What seemed not conceivable some decades ago became rather common: all known magic numbers that are present in the valley of stability disappear far from stability and are replaced by new ones at the drip line. By gathering selected experimental results, beautifully consistent pictures emerge, that very likely take root in the properties of the nuclear forces.The present manuscript describes some of these discoveries and proposes an intuitive understanding of these shell evolutions derived from observations. Extrapolations to yet unstudied regions, as where the explosive r-process nucleosynthesis occurs, are proposed. Some remaining challenges and puzzling questions are also addressed.

    Highly-uniform, hollow glass spheres, which are used for inertial-confinement fusion targets, are formed from metal-organic gel powder feedstock in a drop-tower furnace. The modelling of this gel-to-sphere transformation has consisted of three phases: gel thermochemistry, furnance-to-gel heat transfer, and gravity-driven degradation of the concentricity of the molten shell. The heat transfer from the furnace to the free-falling gel particle was modelled with forced convection. The gel mass, dimensions, and specific heat as well as furnace temperature profile and furnace gas conductivity, were controlled variables. This model has been experimentally verified. In the third phase, a mathematical model was developed to describe the gravity-driven degradation of concentricity in molten glass shells.

    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.

    Kristina Everett

    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.

    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

    A community-based cross-sectional study was carried out among Aboriginal schoolchildren aged 7-12 years living in remote areas in Pos Betau, Pahang, Malaysia to investigate the potential determinants influencing the cognitive function and educational achievement of these children. Cognitive function was measured by intelligence quotient (IQ), while examination scores of selected school subjects were used in assessing educational achievement. Blood samples were collected to assess serum Fe status. All children were screened for soil-transmitted helminthes. Demographic and socio-economic data were collected using pre-tested questionnaires. Almost two-thirds (67·6 %) of the subjects had poor IQ and most of them (72·6 %) had insufficient educational achievement. Output of the stepwise multiple regression model showed that poor IQ was significantly associated with low household income which contributed the most to the regression variance (r2 0·059; P = 0·020). Low maternal education was also identified as a significant predictor of low IQ scores (r2 0·042; P = 0·043). With educational achievement, Fe-deficiency anaemia (IDA) was the only variable to show significant association (r2 0·025; P = 0·015). In conclusion, the cognitive function and educational achievement of Aboriginal schoolchildren are poor and influenced by household income, maternal education and IDA. Thus, effective and integrated measures to improve the nutritional and socio-economic status of rural children would have a pronounced positive effect on their education.

    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.

  4. 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.

    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.

    Srinivasacharya, D.

    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.

    2008-01-01

    In naval architectures, the structure of prismatic shell is used widely. But there is no suitable method to analyze this kind of structure. Stiffened prismatic shell method (SPSM) presented in this paper, is one of the harmonic semi-analytic methods. Theoretically, strong stiffened structure can be analyzed economically and accurately. SPSM is based on the analytical solution of the governing differential equations for orthotropic cylindrical shells. In these differential equations, the torsional stiffness, bending stiffness and the exact position of each stiffener are taken into account with the Heaviside singular function. An algorithm is introduced, in which the actions of stiffeners on shells are replaced by external loads at each stiffener position. Stiffened shells can be computed as non-stiffened shells. Eventually, the displacement solution of the equations is acquired by the introduction of Green function. The stresses in a corrugated transverse bulkhead without pier base of an oil tanker are computed by using SPSM.

    Full Text Available Abstract Background To develop an instrument that predicts diabetes-related vascular disease severity using routinely collected data on Australian Aboriginal and Torres Strait Islander adults with type 2 diabetes, in the absence of diabetes duration. Methods A complex diabetes severity classification system was simplified and adapted for use with an Australian Aboriginal and Torres Strait Islander adult population with type 2 diabetes in north Queensland. Detailed vascular health risks and morbidities were mapped to routinely collected measures. Individual–level health screening, hospital separation and mortality data were linked and used to plot mean monthly in-patient hospital cost and percent mortality by disease severity as defined by the newly developed instrument, to test construct validity. Results The revised instrument consists of four combined diabetes-related microvascular and macrovascular stages that range from least severe (stage 1 to severe irreversible vascular impairment (stage 4. When applied to data of an Aboriginal and Torres Strait Islander Australian population the instrument showed good construct validity, predicting higher hospital cost and mortality as vascular disease severity increased. Conclusions This instrument discriminates between levels of diabetes-related vascular disease severity, displays good construct validity by predicting increased hospital cost and mortality with worsening severity and can be populated with routinely collected data. It may assist with future health service research and its use could be extended to practice settings for health care planning for diabetes management programs and monitoring vascular disease progression.

    Disclosed is a material having a composite particle, the composite particle including an outer shell and a core. The core is made from a lithium alloying material and the outer shell has an inner volume that is greater in size than the core of the lithium alloying material. In some instances, the outer mean diameter of the outer shell is less than 500 nanometers and the core occupies between 5 and 99% of the inner volume. In addition, the outer shell can have an average wall thickness of less than 100 nanometers.

  16. RESONANCE RADIATION OF SUBMERGED INFINITE CYLINDRICAL SHELL

    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.

    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.

  18. OPTIMAL THICKNESS OF A CYLINDRICAL SHELL

    2015-01-01

    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.

    As the missing complement to existing studies of shell galaxies, we carried out a set of self-consistent N-body simulations of a minor merger forming a stellar shell system within a giant elliptical galaxy. We discuss the effect of a phenomenon possibly associated with the galaxy merger simulations --- a presence of multiple generations of shells.

    Physio-chemical changes in oyster shell were examined, and fresh and composted oyster shell meals were compared as lime fertilizers in soybean cultivation. Structural changes in oyster shell were observed by AFM and FE-SEM. We found that grains of the oyster shell surface became smoother and smaller over time. FT-IR analysis indicated the degradation of a chitin-like compound of oyster shell. In chemical analysis, pH (12.3+/-0.24), electrical conductivity (4.1+/-0.24 dS m(-1)), and alkaline powder (53.3+/-1.12%) were highest in commercial lime. Besides, pH was higher in composted oyster shell meal (9.9+/-0.53) than in fresh oyster shell meal (8.4+/-0.32). The highest organic matter (1.1+/-0.08%), NaCl (0.54+/-0.03%), and moisture (15.1+/-1.95%) contents were found in fresh oyster shell meal. A significant higher yield of soybean (1.33 t ha(-1)) was obtained by applying composted oyster shell meal (a 21% higher yield than with fresh oyster shell meal). Thus composting of oyster shell increases the utility of oyster shell as a liming material for crop cultivation.

    Full Text Available BACKGROUND: Linked to extreme rates of chronic heart and kidney disease, pyoderma is endemic amongst Aboriginal children in Australia's Northern Territory (NT. Many of those with pyoderma will also have scabies. We report the results of a community-based collaboration within the East Arnhem Region, which aimed to reduce the prevalence of both skin infections in Aboriginal children. METHODOLOGY/PRINCIPAL FINDINGS: Commencing September 2004, we conducted an ecological study that included active surveillance for skin infections amongst children aged <15 years in five remote East Arnhem communities over a three year period. Screening was undertaken by trained local community workers, usually accompanied by another project team member, using a standard data collection form. Skin infections were diagnosed clinically with the aid of a pictorial flip chart developed for the purpose. Topical 5% permethrin was provided for age-eligible children and all household contacts whenever scabies was diagnosed, whilst those with pyoderma were referred to the clinic for treatment in accordance with current guidelines. In addition, annual mass scabies treatment (5% permethrin cream was offered to all community residents in accordance with current guidelines but was not directly observed. Pyoderma and scabies prevalence per month was determined from 6038 skin assessments conducted on 2329 children. Pyoderma prevalence dropped from 46.7% at baseline to a median of 32.4% (IQR 28.9%-41.0% during the follow-up period - an absolute reduction of 14.7% (IQR 4.7%-16.8%. Compared to the first 18 months of observation, there was an absolute reduction in pyoderma prevalence of 18 cases per 100 children (95%CI -21.0, -16.1, p

    Full Text Available Abstract Background Aboriginal children in remote Australia have high rates of complicated middle ear disease associated with Streptococcus pneumoniae and other pathogens. We assessed the effectiveness of pneumococcal vaccination for prevention of otitis media in this setting. Methods We compared two birth cohorts, one enrolled before (1996–2001, and the second enrolled after introduction of 7-valent pneumococcal conjugate and booster 23-valent polysaccharide vaccine (2001–2004. Source populations were the same for both cohorts. Detailed examinations including tympanometry, video-recorded pneumatic otoscopy and collection of discharge from tympanic membrane perforations, were performed as soon as possible after birth and then at regular intervals until 24 months of life. Analyses (survival, point prevalence and incidence were adjusted for confounding factors and repeated measures with sensitivity analyses of differential follow-up. Results Ninety-seven vaccinees and 51 comparison participants were enrolled. By age 6 months, 96% (81/84 of vaccinees and 100% (41/41 of comparison subjects experienced otitis media with effusion (OME, and by 12 months 89% and 88% experienced acute otitis media (AOM, 34% and 35% experienced tympanic membrane perforation (TMP and 14% and 23% experienced chronic suppurative otitis media (CSOM. Age at the first episode of OME, AOM, TMP and CSOM was not significantly different between the two groups. Adjusted incidence of AOM (incidence rate ratio: 0.88 [95% confidence interval (CI: 0.69–1.13] and TMP (incidence rate ratio: 0.63 [0.36–1.11] was not significantly reduced in vaccinees. Vaccinees experienced less recurrent TMP, 9% (8/95 versus 22% (11/51, (odds ratio: 0.33 [0.11–1.00]. Conclusion Results of this study should be interpreted with caution due to potential bias and confounding. It appears that introduction of pneumococcal vaccination among Aboriginal infants was not associated with significant changes

  9. Statistical Mechanics of Thin Spherical Shells

    Science.gov (United States)

    Košmrlj, Andrej; Nelson, David R.

    2017-01-01

    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 nonlinearly with increasing outward pressure, with the same universal power-law exponent that characterizes the response of fluctuating flat membranes to a uniform tension.

    Full Text Available In this work, the gravitational collapse of a spherically symmetric null shell with the flat interior and a charged Vaidya exterior spacetimes is studied. There is no gravitational impulsive wave present on the null hypersurface which is shear-free and contracting. It follows that there is a critical radius at which the shell bounces and starts expanding.

    2014-01-01

    The mathematical description of the properties of a shell is much more elaborate than those of beam and plate structures. Therefore many engineers and architects are unacquainted with aspects of shell behaviour and design, and are not familiar with sufficiently reliable shell theories for the different shell types as derived in the middle of the 20th century. Rather than contributing to theory development, this university textbook focuses on architectural and civil engineering schools. Of course, practising professionals will profit from it as well. The book deals with thin elastic shells, in particular with cylindrical, conical and spherical types, and with elliptic and hyperbolic paraboloids. The focus is on roofs, chimneys, pressure vessels and storage tanks. Special attention is paid to edge bending disturbance zones, which is indispensable knowledge in FE meshing. A substantial part of the book results from research efforts in the mid 20th century at Delft University of Technology. As such, it is a valua...

    Chowdhury, Shubhankar Roy; Roy, Debasish; Reddy, J N

    2015-01-01

    A state-based peridynamic formulation for linear elastic shells is presented. The emphasis is on introducing, possibly for the first time, a general surface based peridynamic model to represent the deformation characteristics of structures that have one physical dimension much smaller than the other two. A new notion of curved bonds is exploited to cater for force transfer between the peridynamic particles describing the shell. Starting with the three dimensional force and deformation states, appropriate surface based force, moment and several deformation states are arrived at. Upon application on the curved bonds, such states beget the necessary force and deformation vectors governing the motion of the shell. Correctness of our proposal on the peridynamic shell theory is numerically assessed against static deformation of spherical and cylindrical shells and flat plates.

  18. Local shell-to-shell energy transfer via nonlocal interactions in fluid turbulence

    2005-08-01

    In this paper we analytically compute the strength of nonlinear interactions in a triad, and the energy exchanges between wave-number shells in incompressible fluid turbulence. The computation has been done using first-order perturbative field theory. In three dimensions, magnitude of triad interactions is large for nonlocal triads, and small for local triads. However, the shell-to-shell energy transfer rate is found to be local and forward. This result is due to the fact that the nonlocal triads occupy much less Fourier space volume than the local ones. The analytical results on three-dimensional shell-to-shell energy transfer match with their numerical counterparts. In two-dimensional turbulence, the energy transfer rates to the nearby shells are forward, but to the distant shells are backward; the cumulative effect is an inverse cascade of energy.

    2009-01-01

    Effects of solar radiation, rainfall and cultivars on "imperfect shell development" (ISD) of the thin-shelled walnut were studied by means of field investigation and weather data comparison. The results showed that cultivars were the main factor causing the ISD of the thin-shelled walnut. Among the cultivars, Shangsong 6 was the most sensitive one, whose percentage of imperfect shell attained 67.3%, followed by Xiangling (52.7%). However, the rate of imperfect shells in Zhonglin 5 was only 20.9%. It was sug-gested that the main environmental factors contributing to the ISD of the thin-shelled walnut were sunlight intensity and rainfall during the shell-hardening stage.

    1996-01-01

    Millimeter-radius liquid shells are acoustically levitated in an ultrasonic field. Capillary waves are observed on the shells. At low energies (minimal acoustic amplitude, thick shell) a resonance is observed between the symmetric and antisymmetric thin film oscillation modes. At high energies (high acoustic pressure, thin shell) the shell becomes fully covered with high-amplitude waves. Temporal spectra of scattered light from the shell in this regime exhibit a power-law decay indicative of turbulence.

    This effort was directed at developing an electrochemical process for forming uniform and dendrite-free deposits of uranium from molten salts. This process is to be used for the electroformation of free-standing hemispherical shells of uranium for nuclear applications. Electrodeposition of uranium onto a substrate was accomplished with a fused chloride mixture containing 42 wt% UCl{sub 3} and a fused chloride-fluoride mixture containing 4 wt % UF{sub 4}. Under pulsed potential control at 504{degree}C, the chloride-fluoride mixture yielded the widest range of plating conditions for which dendrites could be avoided. Bipolar current pulse plating with both electrolytes gave good results, and successful application of this technique to a large tubular cathode has been demonstrated. 24 refs., 10 figs.

  2. Gravity On-shell Diagrams

    Herrmann, Enrico

    2016-01-01

    We study on-shell diagrams for gravity theories with any number of supersymmetries and find a compact Grassmannian formula in terms of edge variables of the graphs. Unlike in gauge theory where the analogous form involves only $\\dlog$-factors, in gravity there is a non-trivial numerator as well as higher degree poles in the edge variables. Based on the structure of the Grassmannian formula for $\\N=8$ supergravity we conjecture that gravity loop amplitudes also possess similar properties. In particular, we find that there are only logarithmic singularities on cuts with finite loop momentum, poles at infinity are present and loop amplitudes show special behavior on certain collinear cuts. We demonstrate on 1-loop and 2-loop examples that the behavior on collinear cuts is a highly non-trivial property which requires cancellations between all terms contributing to the amplitude.

    2012-01-01

    Full Text Available Type 2 diabetes mellitus (T2DM is classically viewed as a disease of adults caused by poor nutrition, physical inactivity, and obesity. However, with increasing awareness of the heterogeneity of T2DM, new risk factors are being identified that add complexity. Some of these new risk factors have been identified in Canadian people with Aboriginal Oji-Cree heritage, a group that demonstrates one of the highest rates of T2DM in the world. This high prevalence may be due to the rapid change, over the past 50 years, away from their traditional way of life on the land. Another environmental change is the increased rate of pregnancies complicated by obesity, gestational diabetes, or T2DM, resulting in more children being exposed to an abnormal intrauterine environment. Furthermore, the Oji-Cree of central Canada possesses the unique HNF-1α G319S polymorphism associated with reduced insulin secretion. We propose that intrauterine exposure to maternal obesity and T2DM, associated with the HNF-1α G319S polymorphism, results in fetal programming that accelerates the progression of early-onset T2DM. This paper describes the evolution of T2DM in children with a focus on the Oji-Cree people over the past 25 years and the unique prenatal and postnatal gene-environment interaction causing early-onset T2DM.

    Language differences and diverse cultural norms influence the transmission and receipt of information. The online environment provides yet another potential source of miscommunication. Although distance learning has the potential to reach students in cultural groups that have been disenfranchised from traditional higher education settings in the past, intercultural miscommunication is also much more likely to occur through it. There is limited research examining intercultural miscommunication within distance education environments. This article presents the results of a qualitative study that explored the communication experiences of Canadian faculty and Aboriginal students while participating in an online baccalaureate nursing degree program that used various delivery modalities. The microlevel data analysis revealed participants' beliefs and interactions that fostered intercultural miscommunication as well as their recommendations for ensuring respectful and ethically supportive discourses in online courses. The unique and collective influences of intercultural miscommunication on the experiences of faculty and students within the courses are also identified. Instances of ethnocentrism and othering are illustrated, noting the effects that occurred from holding dualistic perspectives of us and them. Lastly, strategies for preventing intercultural miscommunication in online courses are described.

  6. Biomass uptake and fire as controls on groundwater solute evolution on a southeast Australian granite: aboriginal land management hypothesis

    Directory of Open Access Journals (Sweden)

    J. F. Dean

    2014-01-01

    Full Text Available The chemical composition of groundwater and surface water is often considered to be dominated by water–rock interactions, particularly weathering; however, it has been increasingly realised that plant uptake can deplete groundwater and surface water of nutrient elements. Here we show, using geochemical mass balance techniques that at our study site in Southwest Victoria, Australia, water–rock interactions do not control the hydrochemistry. Instead the chemical species provided by rainfall are depleted by plant biomass uptake and exported, predominantly through fire. Regular landscape burning by Aboriginal land users is hypothesized to have caused the depletion of chemical species in groundwater for at least the past 20 000 yr by accelerating the export of elements that would otherwise have been stored within the local biomass. These findings are likely to be representative of southeast Australia, as well as similar climatic regions elsewhere in the globe, and contrast with Northern Hemisphere studies of groundwater and surface water chemistry, where water–rock interactions are the dominant hydrochemical control.

    The purpose of this study was to investigate sexual knowledge, attitudes and behavior of fifth and sixth grade students in aboriginal elementary schools in the Ping-Tung area. A structured questionnaire was administered to 1091 students who were selected by cluster sampling. The results showed: (1) The sexual knowledge score was low but sexual attitudes showed a positive trend. (2) 64.7% and 67.4% of students had at some time seen pictures of male or female sexual organs. (3) About 61% of students had seen sexual magazines or videotapes. (4) 66.2% of male and 88.1% of female students had heard about wet dreams or menstruation before their first experience; more than half of the students thought that wet dreams need treatment. (5) 17.8% of students had masturbation experience, and after that 59.3% of students had fear or guilt feeling. (6) Female students had significantly higher knowledge and attitude scores than male students, Demographic variables produced no significant difference in the above scores. (7) 42.4% of students most desired to know what phenomena indicate sexual maturity. (8) Sex knowledge had significantly positive correlation with sex attitude.

    1989-07-01

    A part-Aboriginal family with beta thalassemia and raised hemoglobin F (HbF) was studied at the molecular level to determine if there were identifiable gene changes associated with increased production of HbF. Two beta thalassemia heterozygotes aged eight years and 18 months had raised HbF levels of 2.9% and 22% respectively. HbF was predominantly G gamma in composition. Five family members were typed for restriction fragment length polymorphisms (RFLPs) using nine restriction enzymes and five DNA probes specific for the beta globin cluster on chromosome 11. RFLPs were combined to construct haplotypes for the beta thalassemia and the high HbF defects. A beta globin subhaplotype comprising only 5' RFLP markers (-(+)-(+) +) co-segregated with the high HbF determinant. This has previously been associated with increased G gamma expression in beta thalassemia and sickle cell anemia. An additional Xmnl RFLP 5' to the G gamma gene, which has been described in individuals with elevated G gamma expression, was also demonstrated in those family members with increased G gamma levels. In this study both the 5' beta globin subhaplotype (-(+)-(+) +) and the Xmnl/gamma RFLP are present in the one family but the relative contributions of each cannot be determined.

    To assess support for 12 potential smoking cessation strategies among pregnant Australian Indigenous women and their antenatal care providers. Cross-sectional surveys of staff and women in antenatal services providing care for Indigenous women in the Northern Territory and New South Wales, Australia. Respondents were asked to indicate the extent to which each of a list of possible strategies would be helpful in supporting pregnant Indigenous women to quit smoking. Current smokers (n = 121) were less positive about the potential effectiveness of most of the 12 strategies than the providers (n = 127). For example, family support was considered helpful by 64 % of smokers and 91 % of providers; between 56 and 62 % of smokers considered advice and support from midwives, doctors or Aboriginal Health Workers likely to be helpful, compared to 85-90 % of providers. Rewards for quitting were considered helpful by 63 % of smokers and 56 % of providers, with smokers rating them more highly and providers rating them lower, than most other strategies. Quitline was least popular for both. This study is the first to explore views of pregnant Australian Indigenous women and their antenatal care providers on strategies to support smoking cessation. It has identified strategies which are acceptable to both providers and Indigenous women, and therefore have potential for implementation in routine care. Further research to explore their feasibility in real world settings, uptake by pregnant women and actual impact on smoking outcomes is urgently needed given the high prevalence of smoking among pregnant Indigenous women.

    In this paper we investigate the limit behavior of the solution to quasi-static Biot's equations in thin poroelastic flexural shells as the thickness of the shell tends to zero and extend the results obtained for the poroelastic plate by Marciniak-Czochra and Mikeli\\'c. We choose Terzaghi's time corresponding to the shell thickness and obtain the strong convergence of the three-dimensional solid displacement, fluid pressure and total poroelastic stress to the solution of the new class of shell equations. The derived bending equation is coupled with the pressure equation and it contains the bending moment due to the variation in pore pressure across the shell thickness. The effective pressure equation is parabolic only in the normal direction. As additional terms it contains the time derivative of the middle-surface flexural strain. Derivation of the model presents an extension of the results on the derivation of classical linear elastic shells by Ciarlet and collaborators to the poroelastic shells case. The n...

  11. A cross-sectional survey assessing the acceptability and feasibility of self-report electronic data collection about health risks from patients attending an Aboriginal Community Controlled Health Service

    Background Aboriginal Australians experience significantly worse health and a higher burden of chronic disease than non-Aboriginal Australians. Electronic self-report data collection is a systematic means of collecting data about health risk factors which could help to overcome screening barriers and assist in the provision of preventive health care. Yet this approach has not been tested in an Aboriginal health care setting. Therefore, the aim of this study was to examine the acceptability and feasibility of a health risk questionnaire administered on a touch screen laptop computer for patients attending an Aboriginal Community Controlled Health Service (ACCHS). Methods In 2012, consecutive adult patients attending an ACCHS in rural New South Wales, Australia, were asked to complete a health risk survey on a touch screen computer. Health risk factors assessed in the questionnaire included smoking status, body mass index, and level of physical activity. The questionnaire included visual cues to improve accuracy and minimise literacy barriers and was completed while participants were waiting for their appointment. Results A total of 188 participants completed the questionnaire, with a consent rate of 71%. The mean time taken to complete the questionnaire was less than 12 minutes. Over 90% of participants agreed that: the questionnaire instructions were easy to follow; the touch screen computer was easy to use; they had enough privacy; the questions were easy to understand; they felt comfortable answering all the questions. Conclusions Results indicate that the use of a touch screen questionnaire to collect information from patients about health risk factors affecting Aboriginal Australians is feasible and acceptable in the ACCHS setting. This approach has potential to improve identification and management of at-risk individuals, therein providing significant opportunities to reduce the burden of disease among Aboriginal Australians.

    In this article we present a theoretical construction of spacetimes with a thin shell that joins two different local cosmic string geometries. We study two types of global manifolds, one representing spacetimes with a thin shell surrounding a cosmic string or an empty region with Minkowski metric, and the other corresponding to wormholes which are not symmetric across the throat located at the shell. We analyze the stability of the static configurations under perturbations preserving the cylindrical symmetry. For both types of geometries we find that the static configurations can be stable for suitable values of the parameters. (orig.)

  13. Bending stresses in Facetted Glass Shells

    A shell structure of glass combines a highly effective structural principle with a material of optimal permeability to light. A facetted shell structure has a piecewise plane geometry, and together the facets form an approximation to a curved surface. A distributed load on a plane-based facetted...... structure will locally cause bending moments in the loaded facets. The bending stresses are dependent on the stiffness of the joints. Approximate solutions are developed to estimate the magnitude of the bending stresses. A FE-model of a facetted glass shell structure is used to validate the expressions...

    We revisit the stability analysis of cylindrical thin shell wormholes which have been studied in literature so far. Our approach is more systematic and in parallel to the method which is used in spherically symmetric thin shell wormholes. The stability condition is summarized as the positivity of the second derivative of an effective potential at the equilibrium radius, i.e. $V^{\\prime \\prime}\\left(a_{0}\\right) >0$. This may serve as the master equation in all stability problems for the cylindrical thin-shell wormholes.

    The book presents the theory of latticed shells as continual systems and describes its applications. It analyses the problems of statics, stability and dynamics. Generally, a classical rod deformation theory is applied. However, in some instances, more precise theories which particularly consider geometrical and physical nonlinearity are employed. A new effective method for solving general boundary value problems and its application for numerical and analytical solutions of mathematical physics and reticulated shell theory problems is described. A new method of solving the shell theory's nonli

    The thermoelastic bending of locally heated orthotropic shells is studied using the classical theory of thermoelasticity of thin shallow orthotropic shells and the method of fundamental solutions. Linear distribution of temperature over thickness and the Newton's law of cooling are assumed. Numerical analysis is carried out for orthotropic shells of arbitrary Gaussian curvature made of a strongly anisotropic material. The behavior of thermal forces and moments near the zone of local heating is studied for two areas of thermal effect: along a coordinate axis and along a circle of unit radius. Generalized conclusions are drawn
