Indigenous Australians have more than double the rate of poor oral health than their non-Indigenous counterparts. Cultural competence of dental and oral health practitioners is fundamental to health care and quality of life in addressing health disparities in minority cultural groups in Australia. Higher education curricula reviews have identified the need for institutions to incorporate Indigenous culture and knowledge more widely into the curricula to improve educational outcomes for Indigenous Australians and to increase cultural competence for all students. The aim of this research was to provide a baseline analysis of Indigenous cultural competence curricula practices to ascertain changes required within Faculty of Dentistry programmes at the University of Sydney to enable students to become more culturally competent upon graduation. Staff and students of the Doctor of Dental Medicine and Bachelor of Oral Health programmes at the Faculty of Dentistry, University of Sydney participated in an online survey. Quantitative analysis of the survey data was conducted using integrated research electronic data capture survey tools, with open-ended questions being coded to common responses for those questions. A total of 69 staff (71%) and 191 students (51%) participated in the online survey. The majority of participants perceived there was limited Indigenous content in the curriculum. Most participants reported that Indigenous curriculum was integrated into several units of study. The main pedagogical method for curriculum delivery was lectures, followed by case studies and group discussions. Although some Indigenous content exists in dental faculty curriculum, in-depth investigation is required to develop a comprehensive, evidenced-based Indigenous cultural competence teaching framework, for integration into Doctor of Dental Medicine and Bachelor of Oral Health curricula. © 2017 John Wiley & Sons A/S.

In Australia, asthma is more prevalent among Indigenous than non-Indigenous people. Awareness of asthma and compliance with management plans are poor, as is engagement with health services in general. The study explored whether offering culturally appropriate music lessons could enhance asthma awareness and engagement to improve asthma and general wellbeing. Two studies undertaken in 2007 and 2009 offered music lessons to Indigenous asthmatics in a junior school and a senior school, an Aboriginal Medical Service and a community centre. Males were taught the didgeridoo and females singing and clap sticks. Associated activities of painting and boomerang throwing were offered. At regular intervals participants were assessed for their asthma status. At completion participants reported on the benefits of the study. Excellent retention occurred in Study 1 for adolescents and junior males but was poor for junior females and adults. Contributory factors to retention were parental and school support for minors and other health factors for adults. Respiratory function improved in males and both males and females reported increased wellbeing. In Study 2 retention of all participants was excellent. In addition there was increased engagement of both participants and their families with medical services. In both studies awareness of asthma and compliance with asthma management plans increased. Social skills improved as did cultural awareness. The offering of music lessons is a culturally appropriate and enjoyable intervention to promote asthma, general health awareness and engagement with medical services.

Objective To evaluate the feasibility and reliability of record linkage of existing population-based data sets to determine Indigenous status among women receiving Pap smears. This method may allow for the first ever population measure of Australian Indigenous women's cervical screening participation rates. Setting/participants A linked data set of women aged 20–69 in the Queensland Pap Smear Register (PSR; 1999–2011) and Queensland Cancer Registry (QCR; 1997–2010) formed the Initial Study Cohort. Two extracts (1995–2011) were taken from Queensland public hospitals data (Queensland Hospital Admitted Patient Data Collection, QHAPDC) for women, aged 20–69, who had ever been identified as Indigenous (extract 1) and had a diagnosis or procedure code relating to cervical cancer (extract 2). The Initial Study Cohort was linked to extract 1, and women with cervical cancer in the initial cohort were linked to extract 2. Outcome measures The proportion of women in the Initial Cohort who linked with the extracts (true -pairs) is reported, as well as the proportion of potential pairs that required clerical review. After assigning Indigenous status from QHAPDC to the PSR, the proportion of women identified as Indigenous was calculated using 4 algorithms, and compared. Results There were 28 872 women (2.1%) from the Initial Study Cohort who matched to an ever Indigenous record in extract 1 (n=76 831). Women with cervical cancer in the Initial Study Cohort linked to 1385 (71%) records in extract 2. The proportion of Indigenous women ranged from 2.00% to 2.08% when using different algorithms to define Indigenous status. The Final Study Cohort included 1 372 823 women (PSR n=1 374 401; QCR n=1955), and 5 062 118 records. Conclusions Indigenous status in Queensland cervical screening data was successfully ascertained through record linkage, allowing for the crucial assessment of the current cervical screening programme for Indigenous women. Our study highlights the need to include Indigenous status on Pap smear request and report forms in any renewed and redesigned cervical screening programme in Australia. PMID:26873047

[ETHICAL CONDUCT FOR RESEARCH INVOLVING INDIGENOUS PEOPLE IN FRANCE: A COMMENT OF THE CNRS ETHICS COMMITTEE OPINION ON THE IMPERATIVE OF FAIRNESS IN THE RELATIONSHIP BETWEEN RESEARCHERS AND INDIGENOUS PEOPLES].

Historically, scientific research and colonization process have maintained very close ties. In order to frame research involving indigenous peoples and to avoid situations of abuse, some States have developed very detailed ethicalframeworks. In France, there are no ethicalframework comparable to those observed in particular in Anglo-Saxon countries like Canada. Extensive discussions were conducted by the Ethics Committee of the CNRS leading to the adoption of an opinion of a high quality but which appears largely unknown and under-exploited. This opinion deals with "the delicate question of the rights of local and indigenous populations during the research projected conducted with their support in developed and developing countries (DCs)". In this paper, we propose to analyze how this opinion can be considered remarkable because it recognizes the current challenges of research projects involving indigenous people, but also because of his recommendations. We still see that the scope of its recommendations is however limited so far although some encouraging experiences like the recent adoption of the CRIOBE centre code of ethics in French Polynesia can be observed.

What are the experiences of Indigenous children with physical disability and their carers of their community-based physiotherapy service? What factors influence their experiences of the physiotherapy service and how could the service be improved? A qualitative study using in-depth, semi-structured open-ended interviews consistent with the researchers' interpretivist perspectives and ethical principles of Indigenous health research. Interviews were audio recorded, transcribed and coded for themes with qualitative research software using inductive analysis. The interviews were then checked for transcription accuracy and the themes were confirmed with the participants. Nine parents and foster carers of children with physical disability aged 0 to 21 years, five children and youth with physical disability aged 8 to 21 years. The data generated three themes, which informed practice recommendations: carers of children with physical disability experience increased demands and complexity in their lives; relationships involving caring, consistency and communication are important to consumers using the physiotherapy service; and being Indigenous influences consumers' experiences in ways that may not be obvious to non-Indigenous service providers. The issue of communication underpinned the participants' experiences throughout these themes. The research highlighted the importance of effective communication, developing relationships, viewing the child wholistically and recognising the influence of being Indigenous on clients' healthcare needs and experiences. The results suggested that community-based physiotherapists adopt a family/person-centred, context-specific approach when working with Indigenous children with a physical disability and their carers.

Human T-cell lymphotropic virus type 1 subtype C molecular variants among indigenous australians: new insights into the molecular epidemiology of HTLV-1 in Australo-Melanesia.

PubMed

HTLV-1 infection is endemic among people of Melanesian descent in Papua New Guinea, the Solomon Islands and Vanuatu. Molecular studies reveal that these Melanesian strains belong to the highly divergent HTLV-1c subtype. In Australia, HTLV-1 is also endemic among the Indigenous people of central Australia; however, the molecular epidemiology of HTLV-1 infection in this population remains poorly documented. Studying a series of 23 HTLV-1 strains from Indigenous residents of central Australia, we analyzed coding (gag, pol, env, tax) and non-coding (LTR) genomic proviral regions. Four complete HTLV-1 proviral sequences were also characterized. Phylogenetic analyses implemented with both Neighbor-Joining and Maximum Likelihood methods revealed that all proviral strains belong to the HTLV-1c subtype with a high genetic diversity, which varied with the geographic origin of the infected individuals. Two distinct Australians clades were found, the first including strains derived from most patients whose origins are in the North, and the second comprising a majority of those from the South of central Australia. Time divergence estimation suggests that the speciation of these two Australian clades probably occurred 9,120 years ago (38,000-4,500). The HTLV-1c subtype is endemic to central Australia where the Indigenous population is infected with diverse subtype c variants. At least two Australian clades exist, which cluster according to the geographic origin of the human hosts. These molecular variants are probably of very ancient origin. Further studies could provide new insights into the evolution and modes of dissemination of these retrovirus variants and the associated ancient migration events through which early human settlement of Australia and Melanesia was achieved.

Indigenous Australians suffer a disproportionate burden of end stage kidney disease (ESKD) but are significantly less likely to receive a transplant. This study explores Indigenous ESKD patients' views on transplantation as a treatment option. The Improving Access to Kidney Transplants (IMPAKT) research program investigated barriers to kidney transplantation for Indigenous Australians. An interview study, conducted in 2005-2006, elicited illness experience narratives from 146 Indigenous patients, including views on transplant. Interviews were conducted at 26 sites that collectively treat the majority of Indigenous ESKD patients. Key themes were identified via team consensus meetings, providing a flexible framework and focus for continued coding. Four inter-related themes were identified in patient commentary: a very high level (90% of respondents) of positive interest in transplantation; patients experienced a range of communication difficulties and felt uninformed about transplant; family involvement in decision-making was constrained by inadequate information; and patients needed to negotiate cultural and social sensitivities around transplantation. Indigenous ESKD patients demonstrated an intense interest in transplantation preferring deceased over living kidney donation. Patients believe transplant is the path most likely to support the re-establishment of their 'normal' family life. Patients described themselves as poorly informed; most had only a rudimentary knowledge of the notion of transplant but no understanding of eligibility criteria, the transplant procedure and associated risks. Patients experienced multiple communication barriers that - taken together - undermine their engagement in treatment decision-making. Families and communities are disempowered because they also lack information to reach a shared understanding of transplantation. Cultural sensitivities associated with transplantation were described but these did not appear to constrain patients in making choices about their own health. Transplant units and local treatment providers should collaborate to develop user-friendly, culturally informed and region-specific patient education programs. Quality improvement cycles should underpin the development of national guidelines for patient education. Noting Indigenous patients' intense interest in transplantation, and nephrologists' concerns regarding poor transplant outcomes, research should prioritise exploring the predictors of transplant outcomes for Indigenous Australians.

Substantial health disparities exist between Māori--the indigenous people of Aotearoa New Zealand--and non-Māori New Zealanders. This article explores the experience and impact of racism on Māori registered nurses within the New Zealand health system. The narratives of 15 Māori registered nurses were analyzed to identify the effects of racism. This Māori nursing cohort and the data on racism form a secondary analysis drawn from a larger research project investigating the experiences of indigenous health workers in New Zealand and Canada. Jones's levels of racism were utilized as a coding frame for the structural analysis of the transcribed Māori registered nurse interviews. Participants experienced racism on institutional, interpersonal, and internalized levels, leading to marginalization and being overworked yet undervalued. Māori registered nurses identified a lack of acknowledgement of dual nursing competencies: while their clinical skills were validated, their cultural skills-their skills in Hauora Māori--were often not. Experiences of racism were a commonality. Racism--at every level--can be seen as highly influential in the recruitment, training, retention, and practice of Māori registered nurses. The nursing profession in New Zealand and other countries of indigenous peoples needs to acknowledge the presence of racism within training and clinical environments as well as supporting indigenous registered nurses to develop and implement indigenous dual cultural-clinical competencies. © The Author(s) 2014.

Gestational diabetes is associated with a high risk of type 2 diabetes. However, progression rates among Indigenous women in Australia who experience high prevalence of gestational diabetes are unknown. This retrospective cohort study includes all births to women at a regional hospital in Far North Queensland, Australia, coded as having 'gestational diabetes' from 1 January 2004 to 31 December 2010 (1098 births) and receiving laboratory postpartum screening from 1 January 2004 to 31 December 2011 (n = 483 births). Women who did not receive postpartum screening were excluded from the denominator. Data were linked between hospital electronic records, routinely collected birth data and laboratories, with sample validation by reviews of medical records. Analysis was conducted using Cox-proportional regression models. Indigenous women had a greater than fourfold risk of developing type 2 diabetes within 8 years of having gestational diabetes, compared with non-Indigenous women (hazards ratio 4.55, 95% confidence interval 2.63-7.88, p < 0.0001). Among women receiving postpartum screening tests, by 3, 5 and 7 years postpartum, 21.9% (15.8-30.0%), 25.5% (18.6-34.3%) and 42.4% (29.6-58.0%) Indigenous women were diagnosed with type 2 diabetes after gestational diabetes, respectively, compared with 4.2% (2.5-7.2%), 5.7% (3.3-9.5%) and 13.5% (7.3-24.2%) non-Indigenous women. Multivariate analysis showed an increased risk of developing type 2 diabetes among women with an early pregnancy body mass index ≥25 kg/m(2) , only partially breastfeeding at hospital discharge and gestational diabetes diagnosis prior to 17 weeks gestation. This study demonstrates that, compared with non-Indigenous women, Indigenous Australian women have a greater than fourfold risk of developing type 2 diabetes after gestational diabetes. Strategies are urgently needed to reduce rates of type 2 diabetes by supporting a healthy weight and breastfeeding and to improve postpartum screening among Indigenous women with gestational diabetes.

Tang, Guoping; Mayes, Melanie; Parker, Jack C

2010-01-01

We implemented the widely used CXTFIT code in Excel to provide flexibility and added sensitivity and uncertainty analysis functions to improve transport parameter estimation and to facilitate model discrimination for multi-tracer experiments on structured soils. Analytical solutions for one-dimensional equilibrium and nonequilibrium convection dispersion equations were coded as VBA functions so that they could be used as ordinary math functions in Excel for forward predictions. Macros with user-friendly interfaces were developed for optimization, sensitivity analysis, uncertainty analysis, error propagation, response surface calculation, and Monte Carlo analysis. As a result, any parameter with transformations (e.g., dimensionless, log-transformed, species-dependent reactions, etc.) couldmore » be estimated with uncertainty and sensitivity quantification for multiple tracer data at multiple locations and times. Prior information and observation errors could be incorporated into the weighted nonlinear least squares method with a penalty function. Users are able to change selected parameter values and view the results via embedded graphics, resulting in a flexible tool applicable to modeling transport processes and to teaching students about parameter estimation. The code was verified by comparing to a number of benchmarks with CXTFIT 2.0. It was applied to improve parameter estimation for four typical tracer experiment data sets in the literature using multi-model evaluation and comparison. Additional examples were included to illustrate the flexibilities and advantages of CXTFIT/Excel. The VBA macros were designed for general purpose and could be used for any parameter estimation/model calibration when the forward solution is implemented in Excel. A step-by-step tutorial, example Excel files and the code are provided as supplemental material.« less

Postcolonial analysis can help rehabilitation providers understand how colonization and racialization create and sustain health inequities faced by indigenous peoples. However, there is little guidance in the literature regarding inclusion of postcolonialism within rehabilitation educational curricula. Therefore, this study explored perspectives regarding educational content related to postcolonialism and indigenous health that rehabilitation students in Canada should learn to increase health equity. This qualitative study involved in-depth, semi-structured interviews with 19 individuals with insight into postcolonialism and health in Canada. Data were analyzed collaboratively to identify, code, and translate themes according to a structured six-phase method. Four themes emerged regarding educational content for rehabilitation students: (1) the historic trauma of colonization and its ongoing impacts on rehabilitation for indigenous peoples; (2) disproportionate health burden and inequitable access to health services; (3) how rehabilitation is related to Indigenous ways of knowing; and (4) why rehabilitation is well-positioned to address health inequities with Indigenous Peoples. Results call for reflection on assumptions underpinning the rehabilitation professions that may unintentionally reinforce health inequities. A postcolonial lens can help rehabilitation educators promote culturally safe services for people whose ill health and disability are linked to the effects of colonization. Implications for Rehabilitation Given the powerful, ongoing effects of colonization and racialization on health and disability, recommendation #24 from the Truth and Reconciliation Commission of Canada calls for the education of health professionals related to Indigenous history, rights, and anti-racism. However, there is little curricula on these areas in the education of rehabilitation professional students or in continuing education programs for practicing clinicians. This is the first study to investigate expert perspectives on content related to postcolonialism and indigenous-settler inequities that should be included in the education of rehabilitation students in Canada. According to the participants in this study, rehabilitation educators in Canada should consider incorporating the following four themes into curricula to better address Indigenous-settler inequities in the context of rehabilitation: (1) the historic trauma of colonization and its ongoing impacts on rehabilitation for Indigenous Peoples in Canada; (2) disproportionate health burden and inequitable access to health services; (3) how rehabilitation is related to Indigenous ways of knowing; and (4) why rehabilitation is well-positioned to rise to the challenge of addressing health inequities with Indigenous Peoples in Canada. Postcolonialism is useful for rehabilitation providers because it is an approach that redirects the focus of problems from Indigenous People to the systems of oppression (specifically colonization and racialization) that cause ill health and disability.

It is important to identify stereotypes about indigenous people because those stereotypes influence prejudice and discrimination, both obstacles to social justice and universal human rights. The purpose of the current study was to document the stereotypes, as held by Guatemalan adolescents, of indigenous Maya people (e.g., Maya) and nonindigenous Ladinos in Guatemala (the 2 main ethnic groups in Guatemala). Guatemalan adolescents (N = 465; 38.3% female; Mage = 14.51 years; SDage = 1.81 years) provided drawings and written characteristics about indigenous Maya and nonindigenous Ladino people, which were then coded for patterns in the data. These patterns included negative stereotypes, such as the Maya being lazy and Ladina women being weak; and positive stereotypes, such as the Maya being caring and warm and Ladino men being successful. There were also interactions between the participants' own gender and ethnicity and how they depicted the target they were assigned. For example, male participants were unlikely to depict male targets of either ethnicity engaging in homemaking activities. Finally, there was evidence of in-group bias based both on gender and ethnicity. These findings suggest that perhaps because indigenous groups around the world share some common negative stereotypes, an understanding of these stereotypes will aid in decreasing prejudice and discrimination against indigenous people, could reduce intergroup conflict, and increase access to basic human rights.

Maternal and newborn health disparities and the health impacts of climate change present grand challenges for global health equity, and there remain knowledge gaps in our understanding of how these challenges intersect. This study examines the pathways through which mothers are affected by seasonal and meteorological factors in sub-Saharan Africa in general, and Kanungu District (Uganda), in particular. We conducted a community-based study consisting of focus group discussions with mothers and interviews with health care workers in Kanungu District. Using a priori and a posteriori coding, we found a diversity of perspectives on the impacts of seasonal and weather exposures, with reporting of more food available in the rainy season. The rainy season was also identified as the period in which women performed physical labour for longer time periods, while work conditions in the dry season were reported to be more difficult due to heat. The causal pathways through which weather and seasonality may be affecting size at birth as reported by Kanungu mothers were consistent with those most frequently reported in the literature elsewhere, including maternal energy balance (nutritional intake and physical exertion output) and seasonal illness. While both Indigenous and non-Indigenous mothers described similar pathways, however, the severity of these experiences differed. Non-Indigenous mothers frequently relied on livestock assets or opportunities for less taxing physical work than Indigenous women, who had fewer options when facing food shortages or transport costs. Findings point to specific entry points for intervention including increased nutritional support in dry season periods of food scarcity, increased diversification of wage labour opportunities, and increased access to contraception. Interventions should be particularly targeted towards Indigenous mothers as they face greater food insecurity, may have fewer sources of income, and face greater overall deprivation than non-Indigenous mothers.

In Australia, significant resources have been invested in producing health promotion best practice guidelines, frameworks and tools (herein referred to as health promotion tools) as a strategy to improve Indigenous health promotion programmes. Yet, there has been very little rigorous implementation research about whether or how health promotion tools are implemented. This paper theorizes the complex processes of health promotion tool implementation in Indigenous comprehensive primary healthcare services. Data were derived from published and grey literature about the development and the implementation of four Indigenous health promotion tools. Tools were theoretically sampled to account for the key implementation types described in the literature. Data were analysed using the grounded-theory methods of coding and constant comparison with construct a theoretical implementation model. An Indigenous Health Promotion Tool Implementation Model was developed. Implementation is a social process, whereby researchers, practitioners and community members collectively interacted in creating culturally responsive health promotion to the common purpose of facilitating empowerment. The implementation of health promotion tools was influenced by the presence of change agents; a commitment to reciprocity and organizational governance and resourcing. The Indigenous Health Promotion Tool Implementation Model assists in explaining how health promotion tools are implemented and the conditions that influence these actions. Rather than simply developing more health promotion tools, our study suggests that continuous investment in developing conditions that support empowering implementation processes are required to maximize the beneficial impacts and effectiveness of health promotion tools. © The Author 2016.

Social Support and Thriving Health: A New Approach to Understanding the Health of Indigenous Canadians

PubMed Central

Richmond, Chantelle A.M.; Ross, Nancy A.; Egeland, Grace M.

2007-01-01

Objectives. We examined the importance of social support in promoting thriving health among indigenous Canadians, a disadvantaged population. Methods. We categorized the self-reported health status of 31625 adult indigenous Canadians as thriving (excellent, very good) or nonthriving (good, fair, poor). We measured social support with indices of positive interaction, emotional support, tangible support, and affection and intimacy. We used multivariable logistic regression analyses to estimate odds of reporting thriving health, using social support as the key independent variable, and we controlled for educational attainment and labor force status. Results. Compared with women reporting low levels of social support, those reporting high levels of positive interaction (odds ratio [OR]=1.4; 95% confidence interval [CI]=1.2, 1.6), emotional support (OR=2.1; 95% CI=1.8, 2.4), and tangible support (OR = 1.4; 95% CI = 1.2, 1.5) were significantly more likely to report thriving health. Among men, only emotional support was significantly related to thriving health (OR=1.7; 95% CI=1.5, 1.9). Thriving health status was also significantly mediated by age, aboriginal status (First Nations, Métis, or Inuit), educational attainment, and labor force status. Conclusions. Social support is a strong determinant of thriving health, particularly among women. Research that emphasizes thriving represents a positive and necessary turn in the indigenous health discourse.

A computer code HALIS, designed to compute the three dimensional flow about shuttle like configurations at angles of attack greater than 25 deg, is described. Results from HALIS are compared where possible with an existing flow field code; such comparisons show excellent agreement. Also, HALIS results are compared with experimental pressure distributions on shuttle models over a wide range of angle of attack. These comparisons are excellent. It is demonstrated that the HALIS code can incorporate equilibrium air chemistry in flow field computations.

Ni-Mn-Ga-Fe/PU polymer composite is prepared to investigate the damping behavior by using an indigenous experimental setup. The excellent damping properties of Ni-Mn-Ga-Fe alloys bonded with polymer matrix makes possible to develop new damping materials which are effective, less expensive and easier than bulk Ni-Mn-Ga. At low frequency, the stress amplitude increases and then smoothly decreases on increasing the frequency.

Objectives We hypothesise that rising prevalence rates of non-communicable diseases (NCDs) increase infection risk and worsen outcomes among socially disadvantaged Indigenous Australians undergoing a rapid epidemiological transition. Design Available pathology, imaging and discharge morbidity codes were retrospectively reviewed for a period of 5 years prior to admission with a bloodstream infection (BSI), 1 January 2003 to 30 June 2007. Participants 558 Indigenous and 55 non-Indigenous community residents of central Australia. Outcome measures The effects of NCDs on risk of infection and death were determined after stratifying by ethnicity. Results The mean annual BSI incidence rates were far higher among Indigenous residents (Indigenous, 937/100 000; non-Indigenous, 64/100 000 person-years; IRR=14.6; 95% CI 14.61 to 14.65, p<0.001). Indigenous patients were also more likely to have previous bacterial infections (68.7% vs 34.6%; respectively, p<0.001), diabetes (44.3% vs 20%; p<0.001), harmful alcohol consumption (37% vs 12.7%; p<0.001) and other communicable diseases (human T-lymphotropic virus type 1, 45.2%; strongyloidiasis, 36.1%; hepatitis B virus, 12.9%). Among Indigenous patients, diabetes increased the odds of current Staphylococcus aureus BSI (OR=1.6, 95% CI 1.0 to 2.5) and prior skin infections (adjusted OR=2.1, 95% CI 1.4 to 3.3). Harmful alcohol consumption increased the odds of current Streptococcus pneumoniae BSI (OR=1.57, 95% CI 1.02 to 2.40) and of previous BSI (OR=1.7, 95% CI 1.1 to 2.5), skin infection (OR=1.7, 95% CI 1.1 to 2.6) or pneumonia (OR=4.3, 95% CI 2.8 to 6.7). Twenty-six per cent of Indigenous patients died at a mean (SD) age of 47±15 years. Complications of diabetes and harmful alcohol consumption predicted 28-day mortality (non-rheumatic heart disease, HR=2.9; 95% CI 1.4 to 6.2; chronic renal failure, HR=2.6, 95%CI 1.0 to 6.5; chronic liver disease, HR=3.3, 95% CI 1.6 to 6.7). Conclusions In a socially disadvantaged population undergoing a rapid epidemiological transition, NCDs are associated with an increased risk of infection and BSI-related mortality. Complex interactions between communicable diseases and NCDs demand an integrated approach to management, which must include the empowerment of affected populations to promote behavioural change.

Objective This study analysed clinical and sociodemographic aspects and follow-up for notified cases of tuberculosis (TB) and explored inequalities in incidence rates and outcome by colour or race and the geographic macro-regions of Brazil. Methods This paper reports the results of a population-based descriptive epidemiological study of all notified cases of TB in Brazil during the period from 01/01/2008 to 31/12/2011. We analysed sociodemographic and clinical variables according to colour or race (white, black, Asian, mixed, and indigenous) and geographic macro-regions of the country (North, Northeast, Central-West, South, and Southeast). Results During the study period, the average incidence of TB in Brazil was 36.7 cases per 100,000 inhabitants, with the highest rates occurring in the North and Southeast regions. The analysis of TB notifications by colour or race revealed that the indigenous population presented the highest incidence rates in all macro-regions except the South, where higher rates were reported in black patients. ‘Cured’ was the most frequently reported treatment outcome for all skin colour categories. The highest cure rate occurred among the indigenous population (76.8%), while the lowest cure rate occurred among the black population (70.7%). Rates of treatment default were highest among blacks (10.5%) and lowest among the indigenous population (6.9%). However, the fatality rate was similar across race categories, varying between 2.8% and 3.8% for whites and the indigenous population, respectively. The lowest cure rates were observed when follow-up was inadequate (58.3%), and the highest was observed when the follow-up was classified as excellent (96.8%). Conclusions This study revealed that—apart from the heterogeneous distribution of TB among the Brazilian macro-regions—ethnic-racial inequalities exist in terms of clinical-epidemiological characteristics and incidence rates as well as follow-up for cases undergoing treatment. The highest rates of TB occurred among the indigenous people. PMID:27176911

Researchers are required to seek consent from Indigenous communities prior to conducting research but there is inadequate information about how Indigenous people understand and become fully engaged with this consent process. Few studies evaluate the preference or understanding of the consent process for research with Indigenous populations. Lack of informed consent can impact on research findings. The Picture Talk Project was initiated with senior Aboriginal leaders of the Fitzroy Valley community situated in the far north of Western Australia. Aboriginal people were interviewed about their understanding and experiences of research and consent processes. Transcripts were analysed using NVivo10 software with an integrated method of inductive and deductive coding and based in grounded theory. Local Aboriginal interpreters validated coding. Major themes were defined and supporting quotes sourced. Interviews with Aboriginal leaders (n = 20) were facilitated by a local Aboriginal Community Navigator who could interpret if necessary and provide cultural guidance. Participants were from all four major local language groups of the Fitzroy Valley; aged 31 years and above; and half were male. Themes emerging from these discussions included Research-finding knowledge; Being respectful of Aboriginal people, Working on country, and Being flexible with time; Working together with good communication; Reciprocity-two-way learning; and Reaching consent. The project revealed how much more there is to be learned about how research with remote Aboriginal communities should be conducted such that it is both culturally respectful and, importantly, meaningful for participants. We identify important elements in community consultation about research and seeking consent.

The processing of the input and output files of quantum chemical calculations often necessitates a spreadsheet as a key component of the workflow. Spreadsheet packages with a built-in programming language editor can automate the steps involved and thus provide a direct link between processing files and the spreadsheet. This helps to reduce user-interventions as well as the need to switch between different programs to carry out each step. The ExcelAutomat tool is the implementation of this method in Microsoft Excel (MS Excel) using the default Visual Basic for Application (VBA) programming language. The code in ExcelAutomat was adapted to work with the platform-independent open-source LibreOffice Calc, which also supports VBA. ExcelAutomat provides an interface through the spreadsheet to automate repetitive tasks such as merging input files, splitting, parsing and compiling data from output files, and generation of unique filenames. Selected extracted parameters can be retrieved as variables which can be included in custom codes for a tailored approach. ExcelAutomat works with Gaussian files and is adapted for use with other computational packages including the non-commercial GAMESS. ExcelAutomat is available as a downloadable MS Excel workbook or as a LibreOffice workbook.

This study evaluated the potential for gene transfer of a large catabolic plasmid from an introduced organism to indigenous soil recipients. The donor organism Alcaligenes eutrophus JMP134 contained the 80-kb plasmid pJP4, which contains genes that code for mercury resistance. Genes on this plasmid plus chromosomal genes also allow degradation of 2,4-dichloruphenoxyacetic acid (2,4-D). When JMP134 was inoculated into a nonsterile soil microcosm amended with 1,000 micrograms of 2,4-D g-1, significant (10(6) g of soil-1) populations of indigenous recipients or transconjugants arose. These transconjugants all contained an 80-kb plasmid similar in size to pJP4, and all degraded 2,4-D. In addition, all transconjugants were resistant to mercury and contained the tfdB gene of pJP4 as detected by PCR. No mercury-resistant, 2,4-D-degrading organisms with large plasmids or the tfdB gene were found in the 2,4-D-amended but uninoculated control microcosm. These data clearly show that the plasmid pJP4 was transferred to indigenous soil recipients. Even more striking is the fact that not only did the indigenous transconjugant population survive and proliferate but also enhanced rates of 2,4-D degradation occurred relative to microcosms in which no such gene transfer occurred. Overall, these data indicate that gene transfer from introduced organisms is an effective means of bioaugmentation and that survival of the introduced organism is not a prerequisite for biodegradation that utilizes introduced biodegradative genes.

Medical school Web sites often advance arguments to claim institutional excellence and appeal to the "best and the brightest" who might join their institutions as medical students. What do these texts communicate about institutional excellence, or the excellence of potential applicants to medical school? How are discourses related to social accountability, such as those concerning diversity and equity, represented? From July through December 2010, using the concepts of excellence, equity, and diversity, the authors examined the discourses identified on the Web sites of Canada's 17 medical schools, focusing on faculty welcome pages, deans' messages, and those pages specifically targeting applicants to medicine. Institutional prestige and applicant suitability were generally promoted through discourses of academic excellence such as research, innovation, and global positioning. Service-to-society discourses were much less prominent. Diversity discourses emerged primarily as appeals to institutions' cosmopolitan sophistication. Equity, when mentioned, tended to focus on increasing the participation of indigenous and rural students in medicine. Institutional positioning can be situated on a continuum from the more "centric" (typical academic excellence claims) to the more "eccentric" (excellence claims grounded in local contexts such as service to a region or constituency). Discourses can play a central role in regulating social institutional practices. It is worthwhile for medical schools to examine the messages that medical schools are communicating on their Web sites. If schools are to move beyond prestige-based characterizations of excellence and build a socially accountable profession, open and inclusive discussions are needed.

The characteristics, implementation and effects of Aboriginal and Torres Strait Islander health promotion tools: a systematic literature search

PubMed Central

2014-01-01

Background Health promotion by and with Aboriginal and Torres Strait Islander (hereafter Indigenous) Australians is critically important given a wide gap in health parity compared to other Australians. The development and implementation of step-by-step guides, instruments, packages, frameworks or resources has provided a feasible and low-resource strategy for strengthening evidence-informed health promotion practice. Yet there has been little assessment of where and how these tools are implemented or their effectiveness. This paper reviews the characteristics, implementation and effects of Indigenous health promotion tools. Methods Indigenous health promotion tools were identified through a systematic literature search including a prior scoping study, eight databases, references of other reviews and the authors’ knowledge (n = 1494). Documents in the peer reviewed and grey literature were included if they described or evaluated tools designed, recommended or used for strengthening Indigenous Australian health promotion. Eligible publications were entered into an Excel spreadsheet and documented tools classified according to their characteristics, implementation and effects. Quality was appraised using the Dictionary for Effective Public Health Practice Project (EPHPP) and Critical Appraisal Skills Program (CASP) tools for quantitative and qualitative studies respectively. Results The review found that Indigenous health promotion tools were widely available. Of 74 publications that met inclusion criteria, sixty (81%) documented tools developed specifically for the Indigenous Australian population. All tools had been developed in reference to evidence; but only 22/74 (30%) publications specified intended or actual implementation, and only 11/74 (15%) publications evaluated impacts of the implemented tools. Impacts included health, environmental, community, organisational and health care improvements. The quality of impact evaluations was strong for only five (7%) studies. Conclusions The small number and generally moderate quality of implementation and evaluation studies means that little is known about how tools work to strengthen Indigenous health promotion practice. The findings suggest that rather than continuing to invest in tool development, practitioners, policy makers and researchers could evaluate the implementation and effects of existing tools and publish the results. There is a need for long-term investment in research to review the current use of health promotion tools and the factors that are likely to enhance their implementation. PMID:25012401

Biopiracy mainly focuses on the use of biological resources and/or knowledge of indigenous tribes or communities without allowing them to share the revenues generated out of economic exploitation or other non-monetary incentives associated with the resource/knowledge. Based on collaborations of scientists from five continents, we have created a communication platform to discuss not only scientific topics, but also more general issues with social relevance. This platform was termed 'PhytCancer -Phytotherapy to Fight Cancer' (www.phyt-cancer.uni-mainz.de). As a starting point, we have chosen the topic "biopiracy", since we feel this is of pragmatic significance for scientists working with medicinal plants. It was argued that the patenting of herbs or natural products by pharmaceutical corporations disregarded the ownership of the knowledge possessed by the indigenous communities on how these substances worked. Despite numerous court decisions in U.S.A. and Europe, several international treaties, (e.g. from United Nations, World Health Organization, World Trade Organization, the African Unity and others), sharing of a rational set of benefits amongst producers (mainly pharmaceutical companies) and indigenous communities is yet a distant reality. In this paper, we present an overview of the legal frameworks, discuss some exemplary cases of biopiracy and bioprospecting as excellent forms of utilization of natural resources. We suggest certain perspectives, by which we as scientists, may contribute towards prevention of biopiracy and also to foster the fair utilization of natural resources. We discuss ways, in which the interests of indigenous people especially from developing countries can be secured. Copyright © 2015 Elsevier GmbH. All rights reserved.

Maternal alcohol use disorder is a risk factor for a range of developmental outcomes in children. This study examines school achievement in children of Indigenous and non-Indigenous mothers with an alcohol-related diagnosis. This is a Western Australian population cohort study of mothers with a record of an alcohol-related diagnosis classified by the International Classification of Diseases Revisions 9/10 codes as recorded on administrative databases, and of their offspring born between 1989 and 2007 (n=18 486 exposed children), with a frequency matched comparison cohort of mothers with no record of alcohol diagnosis and their offspring (n=48 262 comparison children). Records were linked with school achievement data for numeracy and literacy from Years 3, 5, 7 and 9 (age range: ~8-14 years) based on statewide and national testing. Mixed multivariate models with a random intercept per child were used to assess the relationship between exposure and the timing of exposure with failure to meet minimum standardised benchmarks. Academic achievement was lower in all testing domains (reading, writing, spelling and numeracy) among children of mothers with an alcohol diagnosis and persisted across all year groups examined. The highest ORs at Year 9 for non-Indigenous children were in reading (adjusted OR (aOR) 1.6, 95% CI 1.4 to 1.8) and in writing for Indigenous children (aOR 2.0, 95% CI 1.8 to 2.3). Children of mothers with alcohol use disorders are at risk of not meeting minimum educational benchmarks in numeracy and literacy, with the risk highest among Indigenous children. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Torlapati, Jagadish; Prabhakar Clement, T.

2013-01-01

We present the details of a comprehensive numerical modeling tool, RT1D, which can be used for simulating biochemical and geochemical reactive transport problems. The code can be run within the standard Microsoft EXCEL Visual Basic platform, and it does not require any additional software tools. The code can be easily adapted by others for simulating different types of laboratory-scale reactive transport experiments. We illustrate the capabilities of the tool by solving five benchmark problems with varying levels of reaction complexity. These literature-derived benchmarks are used to highlight the versatility of the code for solving a variety of practical reactive transport problems. The benchmarks are described in detail to provide a comprehensive database, which can be used by model developers to test other numerical codes. The VBA code presented in the study is a practical tool that can be used by laboratory researchers for analyzing both batch and column datasets within an EXCEL platform.

Considerations of multicultural science and curriculum reform: A content analysis of state-adopted biology textbooks in Florida

NASA Astrophysics Data System (ADS)

Delgato, Margaret H.

The purpose of this investigation was to determine the extent to which multicultural science education, including indigenous knowledge representations, had been infused within the content of high school biology textbooks. The study evaluated the textbook as an instructional tool and framework for multicultural science education instruction by comparing the mainstream content to indigenous knowledge perspectives portrayed in the student and teacher editions of 34 textbooks adopted in Florida within the last four adoption cycles occurring from 1990 to 2006. The investigation involved a content analysis framed from a mixed methods approach. Emphasis was placed, in consideration of the research questions and practicality of interpreting text with the potential for multiple meanings, within qualitative methods. The investigation incorporated five strategies to assess the extent of multicultural content: (1) calculation of frequency of indigenous representations through the use of a tally; (2) assessment of content in the teacher editions by coding the degree of incorporation of multicultural content; (3) development of an archaeology of statements to determine the ways in which indigenous representations were incorporated into the content; (4) use of the Evaluation Coefficient Analysis (ECO) to determine extent of multicultural terminologies within content; and (5) analysis of visuals and illustrations to gauge percentages of depictions of minority groups. Results indicated no solid trend in an increase of inclusion of multicultural content over the last four adoption cycles. Efforts at most reduced the inclusion of indigenous representations and other multicultural content to the level of the teacher edition distributed among the teacher-interleafed pages or as annotations in the margins. Degree of support of multicultural content to the specific goals and objectives remained limited across all four of the adoption cycles represented in the study. Emphasis on standardized testing appeared in the six textbooks representing the most recent adoption cycle. Recommendations included increased efforts to identify quality of content by including input from scholars in the field of multicultural education as well as indigenous peoples in the creation of textbook content. Recommendations also included further clarification of the definition of science within multicultural science education frameworks, indigenous knowledge as compared to Western science and pseudoscienc e, and scientific literacy as a central focus to a multicultural science education meant to address the needs of an increasingly diverse student population and prime-age workforce.

Construction of type-II QC-LDPC codes with fast encoding based on perfect cyclic difference sets

2017-09-01

In view of the problems that the encoding complexity of quasi-cyclic low-density parity-check (QC-LDPC) codes is high and the minimum distance is not large enough which leads to the degradation of the error-correction performance, the new irregular type-II QC-LDPC codes based on perfect cyclic difference sets (CDSs) are constructed. The parity check matrices of these type-II QC-LDPC codes consist of the zero matrices with weight of 0, the circulant permutation matrices (CPMs) with weight of 1 and the circulant matrices with weight of 2 (W2CMs). The introduction of W2CMs in parity check matrices makes it possible to achieve the larger minimum distance which can improve the error- correction performance of the codes. The Tanner graphs of these codes have no girth-4, thus they have the excellent decoding convergence characteristics. In addition, because the parity check matrices have the quasi-dual diagonal structure, the fast encoding algorithm can reduce the encoding complexity effectively. Simulation results show that the new type-II QC-LDPC codes can achieve a more excellent error-correction performance and have no error floor phenomenon over the additive white Gaussian noise (AWGN) channel with sum-product algorithm (SPA) iterative decoding.

Evaluating program outcomes without considering how the program was implemented can cause misunderstandings and inefficiencies when initiating program improvements. In conjunction with a program evaluation, reported elsewhere, this paper theorises the process of implementing an Indigenous Australian maternal and child health program. The Baby Basket program was developed in 2009 for the remote Cape York region and aimed to improve the attendance and engagement of Indigenous women at antenatal and postnatal clinics through providing three baskets of maternal and baby goods and associated health education. Constructivist grounded theory methods were used to generate and analyse data from qualitative interviews and focus groups with Indigenous women who received the baskets, their extended family members, and healthcare workers who delivered them. Data was coded in NVivo with concepts iteratively compared until higher order constructs and their relationships could be modelled to explain the common purpose for participants, the process involved in achieving that purpose, key strategies, conditions and outcomes. Theoretical terms are italicised. Program implementation entailed empowering families through a process of engaging and relating Murri (Queensland Indigenous) way. Key influencing conditions of the social environment were the remoteness of communities, keeping up with demand, families' knowledge, skills and roles and organisational service approaches and capacities. Engaging and relating Murri way occurred through four strategies: connecting through practical support, creating a culturally safe practice, becoming informed and informing others, and linking at the clinic. These strategies resulted in women and families taking responsibility for health through making healthy choices, becoming empowered health consumers and advocating for community changes. The theoretical model was applied to improve and revise Baby Basket program implementation, including increased recognition of the importance of empowering families by extending the home visiting approach up to the child's third birthday. Engaging and relating Murri way was strengthened by formal recognition and training of Indigenous health workers as program leaders. This theoretical model of program implementation was therefore useful for guiding program improvements, and could be applicable to other Indigenous maternal and child health programs.

A second macro measures darkness along a defined path to identify latewood–earlywood transition in conifers, and a third shows the potential for automatic detection of boundaries. Written in Visual Basic for Applications, the code makes use of the advantages of existing programs and is consequently very economic and relatively simple to adjust to the requirements of specific projects or to expand making use of already available code.

Health administrative databases may provide rich sources of data for the study of outcomes following burn. We aimed to determine the accuracy of International Classification of Diseases diagnoses codes for burn in a population-based administrative database. Data from a regional burn center's clinical registry of patients admitted between 2006-2013 were linked to administrative databases. Burn total body surface area (TBSA), depth, mechanism, and inhalation injury were compared between the registry and administrative records. The sensitivity, specificity, and positive and negative predictive values were determined, and coding agreement was assessed with the kappa statistic. 1215 burn center patients were linked to administrative records. TBSA codes were highly sensitive and specific for ≥10 and ≥20% TBSA (89/93% sensitive and 95/97% specific), with excellent agreement (κ, 0.85/κ, 0.88). Codes were weakly sensitive (68%) in identifying ≥10% TBSA full-thickness burn, though highly specific (86%) with moderate agreement (κ, 0.46). Codes for inhalation injury had limited sensitivity (43%) but high specificity (99%) with moderate agreement (κ, 0.54). Burn mechanism had excellent coding agreement (κ, 0.84). Administrative data diagnosis codes accurately identify burn by burn size and mechanism, while identification of inhalation injury or full-thickness burns is less sensitive but highly specific.

The Chuanzhong black goat (Capra hircus) is a breed native to southwest of China. Its complete mitochondrial genome is 16,641 nt in length, consisting of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a non-coding control region. As in other mammals, most mitochondrial genes are encoded on the heavy strand, except for ND6 and eight tRNA genes, which are encoded on the light strand. Its overall base composition is A: 33.5%, T: 27.3%, C: 26.1%, and G: 13.1%. The complete mitogenome of the Chinese indigenous breed of goat could provide a basic data for further phylogenetics analysis.

Emerging countries frequently afflicted by waterborne diseases require safe and cost-efficient production of drinking water, a task that is becoming more challenging as many rivers carry a high degree of pollution. A study was conducted on the banks of the Yamuna River, Delhi, India, to ascertain if riverbank filtration (RBF) can significantly improve the quality of the highly polluted surface water in terms of virus removal (coliphages, enteric viruses). Human adenoviruses and noroviruses, both present in the Yamuna River in the range of 10(5) genomes/100 mL, were undetectable after 50 m infiltration and approximately 119 days of underground passage. Indigenous somatic coliphages, used as surrogates of human pathogenic viruses, underwent approximately 5 log10 removal after only 3.8 m of RBF. The initial removal after 1 m was 3.3 log10, and the removal between 1 and 2.4 m and between 2.4 and 3.8 m was 0.7 log10 each. RBF is therefore an excellent candidate to improve the water situation in emerging countries with respect to virus removal.

Theoretical analysis has long indicated that feedback improves the error exponent but not the capacity of pointto- point memoryless channels. The analytic and empirical results indicate that at short blocklength regime, practical rate-compatible punctured convolutional (RCPC) codes achieve low latency with the use of noiseless feedback. In 3GPP, standard rate-compatible turbo codes (RCPT) did not outperform the convolutional codes in the short blocklength regime. The reason is the convolutional codes for low number of states can be decoded optimally using Viterbi decoder. Despite excellent performance of convolutional codes at very short blocklengths, the strength of convolutional codes does not scale with the blocklength for a fixed number of states in its trellis.

Collisionless stellar hydrodynamics as an efficient alternative to N-body methods

The dominant constituents of the Universe's matter are believed to be collisionless in nature and thus their modelling in any self-consistent simulation is extremely important. For simulations that deal only with dark matter or stellar systems, the conventional N-body technique is fast, memory efficient and relatively simple to implement. However when extending simulations to include the effects of gas physics, mesh codes are at a distinct disadvantage compared to Smooth Particle Hydrodynamics (SPH) codes. Whereas implementing the N-body approach into SPH codes is fairly trivial, the particle-mesh technique used in mesh codes to couple collisionless stars and dark matter to the gas on the mesh has a series of significant scientific and technical limitations. These include spurious entropy generation resulting from discreteness effects, poor load balancing and increased communication overhead which spoil the excellent scaling in massively parallel grid codes. In this paper we propose the use of the collisionless Boltzmann moment equations as a means to model the collisionless material as a fluid on the mesh, implementing it into the massively parallel FLASH Adaptive Mesh Refinement (AMR) code. This approach which we term `collisionless stellar hydrodynamics' enables us to do away with the particle-mesh approach and since the parallelization scheme is identical to that used for the hydrodynamics, it preserves the excellent scaling of the FLASH code already demonstrated on peta-flop machines. We find that the classic hydrodynamic equations and the Boltzmann moment equations can be reconciled under specific conditions, allowing us to generate analytic solutions for collisionless systems using conventional test problems. We confirm the validity of our approach using a suite of demanding test problems, including the use of a modified Sod shock test. By deriving the relevant eigenvalues and eigenvectors of the Boltzmann moment equations, we are able to use high order accurate characteristic tracing methods with Riemann solvers to generate numerical solutions which show excellent agreement with our analytic solutions. We conclude by demonstrating the ability of our code to model complex phenomena by simulating the evolution of a two-armed spiral galaxy whose properties agree with those predicted by the swing amplification theory.

One-weight authentication code for multi-user quantum key distribution (QKD) is proposed. The code is developed for Optical Code Division Multiplexing (OCDMA) based QKD network. A unique address assigned to individual user, coupled with degrading probability of predicting the source of the qubit transmitted in the channel offer excellent secure mechanism against any form of channel attack on OCDMA based QKD network. Flexibility in design as well as ease of modifying the number of users are equally exceptional quality presented by the code in contrast to Optical Orthogonal Code (OOC) earlier implemented for the same purpose. The code was successfully applied to eight simultaneous users at effective key rate of 32 bps over 27 km transmission distance.

The law of the mother.

The Congress Workshop on People and Protected Areas convened to discuss the need to combine modern science and traditional knowledge to effect sustainable development among indigenous peoples in the world. The founder of the Fundacion Pro-Sierra Nevada de Santa Marta talked about development of training programs for displaced farmers and rehabilitation of Indian lands and villages in the Sierra Nevada of northern Colombia. The 3 indigenous peoples (Kogi, Arsario, and Arhuaco Indians) have only recently regained title to their forebears' lands. In fact, in 1990, the government of Colombia gave about 25% of the country back to indigenous populations. The forebears of the Kogi, Arsario, and Arhuaco Indians constructed great stone cities and advanced systems of agriculture, terracing, and irrigation. The Indians have lived under the Law of the Mother for thousands of years. This code dictates human behavior so that humans are in unity with plant and animal cycles, star movements, climatic phenomena, and the sacred geography of the coastal mountains. They are so much an integral part of their ecosystem that they even limit their population size. Now they resurrect villages in 2 national parks and indigenous reservations. Farmers who colonized the area since the 1960s must now leave the reserves and begin anew in nearby buffer zones. Here they learn revitalized agricultural techniques to abandon their illegal marijuana, cocaine, and poppy farming. At the workshop, participants also learned about conservation activities of the Imgrauen in the Banc d'Arguin National Park in Mauritania who continue to use dolphins to catch mullet. In India, the Bisnoi people living in the Rajasthan desert have established their own unofficial protected areas to keep the fragile ecosystem. Other examples were in Niger and Central Europe. The workshop participants agreed that recognition of land tenure and intellectual property rights were high priorities.

Neal, William

2015-06-01

Magnetohydrodynamic (MHD) codes are currently being developed, and used, to predict the behaviour of electrically-driven flyer-plates. These codes are of particular interest to the design of exploding foil initiator (EFI) detonators but there is a distinct lack of comparison with high-fidelity experimental data. This study aims to compare a MHD code with a collection of temporally and spatially resolved diagnostics including PDV, dual-axis imaging and streak imaging. The results show the code's excellent representation of the flyer-plate launch and highlight features within the experiment that the model fails to capture.

An edge preserving differential image coding scheme

Rost, Martin C.; Sayood, Khalid

1992-01-01

Differential encoding techniques are fast and easy to implement. However, a major problem with the use of differential encoding for images is the rapid edge degradation encountered when using such systems. This makes differential encoding techniques of limited utility, especially when coding medical or scientific images, where edge preservation is of utmost importance. A simple, easy to implement differential image coding system with excellent edge preservation properties is presented. The coding system can be used over variable rate channels, which makes it especially attractive for use in the packet network environment.

'Achievement, pride and inspiration': outcomes for volunteer role models in a community outreach program in remote Aboriginal communities.

Cinelli, Renata L; Peralta, Louisa R

2015-01-01

There is growing support for the prosocial value of role modelling in programs for adolescents and the potentially positive impact role models can have on health and health behaviours in remote communities. Despite known benefits for remote outreach program recipients, there is limited literature on the outcomes of participation for role models. Twenty-four role models participated in a remote outreach program across four remote Aboriginal communities in the Northern Territory, Australia (100% recruitment). Role models participated in semi-structured one-on-one interviews. Transcripts were coded and underwent thematic analysis by both authors. Cultural training, Indigenous heritage and prior experience contributed to general feelings of preparedness, yet some role models experienced a level of culture shock, being confronted by how disparate the communities were to their home communities. Benefits of participation included exposure to and experience with remote Aboriginal peoples and community, increased cultural knowledge, personal learning, forming and building relationships, and skill development. Effective role model programs designed for remote Indigenous youth can have positive outcomes for both role models and the program recipients. Cultural safety training is an important factor for preparing role models and for building their cultural competency for implementing health and education programs in remote Indigenous communities in Australia. This will maximise the opportunities for participants to achieve outcomes and minimise their culture shock.

The effects of European colonization on the genomes of Native Americans may have produced excesses of potentially deleterious features, mainly due to the severe reductions in population size and corresponding losses of genetic diversity. This assumption, however, neither considers actual genomic patterns that existed before colonization nor does it adequately capture the effects of admixture. In this study, we analyze the whole-exome sequences of modern and ancient individuals from a Northwest Coast First Nation, with a demographic history similar to other indigenous populations from the Americas. We show that in approximately ten generations from initial European contact, the modern individuals exhibit reduced levels of novel and low-frequency variants, a lower proportion of potentially deleterious alleles, and decreased heterozygosity when compared to their ancestors. This pattern can be explained by a dramatic population decline, resulting in the loss of potentially damaging low-frequency variants, and subsequent admixture. We also find evidence that the indigenous population was on a steady decline in effective population size for several thousand years before contact, which emphasizes regional demography over the common conception of a uniform expansion after entry into the Americas. This study examines the genomic consequences of colonialism on an indigenous group and describes the continuing role of gene flow among modern populations.

Geodynamics for Everyone: Robust Finite-Difference Heat Transfer Models using MS Excel 2007 Spreadsheets

NASA Astrophysics Data System (ADS)

Grose, C. J.

2008-05-01

Numerical geodynamics models of heat transfer are typically thought of as specialized topics of research requiring knowledge of specialized modelling software, linux platforms, and state-of-the-art finite-element codes. I have implemented analytical and numerical finite-difference techniques with Microsoft Excel 2007 spreadsheets to solve for complex solid-earth heat transfer problems for use by students, teachers, and practicing scientists without specialty in geodynamics modelling techniques and applications. While implementation of equations for use in Excel spreadsheets is occasionally cumbersome, once case boundary structure and node equations are developed, spreadsheet manipulation becomes routine. Model experimentation by modifying parameter values, geometry, and grid resolution makes Excel a useful tool whether in the classroom at the undergraduate or graduate level or for more engaging student projects. Furthermore, the ability to incorporate complex geometries and heat-transfer characteristics makes it ideal for first and occasionally higher order geodynamics simulations to better understand and constrain the results of professional field research in a setting that does not require the constraints of state-of-the-art modelling codes. The straightforward expression and manipulation of model equations in excel can also serve as a medium to better understand the confusing notations of advanced mathematical problems. To illustrate the power and robustness of computation and visualization in spreadsheet models I focus primarily on one-dimensional analytical and two-dimensional numerical solutions to two case problems: (i) the cooling of oceanic lithosphere and (ii) temperatures within subducting slabs. Excel source documents will be made available.

Efficient Helicopter Aerodynamic and Aeroacoustic Predictions on Parallel Computers

Wissink, Andrew M.; Lyrintzis, Anastasios S.; Strawn, Roger C.; Oliker, Leonid; Biswas, Rupak

1996-01-01

This paper presents parallel implementations of two codes used in a combined CFD/Kirchhoff methodology to predict the aerodynamics and aeroacoustics properties of helicopters. The rotorcraft Navier-Stokes code, TURNS, computes the aerodynamic flowfield near the helicopter blades and the Kirchhoff acoustics code computes the noise in the far field, using the TURNS solution as input. The overall parallel strategy adds MPI message passing calls to the existing serial codes to allow for communication between processors. As a result, the total code modifications required for parallel execution are relatively small. The biggest bottleneck in running the TURNS code in parallel comes from the LU-SGS algorithm that solves the implicit system of equations. We use a new hybrid domain decomposition implementation of LU-SGS to obtain good parallel performance on the SP-2. TURNS demonstrates excellent parallel speedups for quasi-steady and unsteady three-dimensional calculations of a helicopter blade in forward flight. The execution rate attained by the code on 114 processors is six times faster than the same cases run on one processor of the Cray C-90. The parallel Kirchhoff code also shows excellent parallel speedups and fast execution rates. As a performance demonstration, unsteady acoustic pressures are computed at 1886 far-field observer locations for a sample acoustics problem. The calculation requires over two hundred hours of CPU time on one C-90 processor but takes only a few hours on 80 processors of the SP2. The resultant far-field acoustic field is analyzed with state of-the-art audio and video rendering of the propagating acoustic signals.

Maximum likelihood decoding analysis of Accumulate-Repeat-Accumulate Codes

2004-01-01

Repeat-Accumulate (RA) codes are the simplest turbo-like codes that achieve good performance. However, they cannot compete with Turbo codes or low-density parity check codes (LDPC) as far as performance is concerned. The Accumulate Repeat Accumulate (ARA) codes, as a subclass of LDPC codes, are obtained by adding a pre-coder in front of RA codes with puncturing where an accumulator is chosen as a precoder. These codes not only are very simple, but also achieve excellent performance with iterative decoding. In this paper, the performance of these codes with (ML) decoding are analyzed and compared to random codes by very tight bounds. The weight distribution of some simple ARA codes is obtained, and through existing tightest bounds we have shown the ML SNR threshold of ARA codes approaches very closely to the performance of random codes. We have shown that the use of precoder improves the SNR threshold but interleaving gain remains unchanged with respect to RA code with puncturing.

Multiple description distributed image coding with side information for mobile wireless transmission

NASA Astrophysics Data System (ADS)

Wu, Min; Song, Daewon; Chen, Chang Wen

2005-03-01

Multiple description coding (MDC) is a source coding technique that involves coding the source information into multiple descriptions, and then transmitting them over different channels in packet network or error-prone wireless environment to achieve graceful degradation if parts of descriptions are lost at the receiver. In this paper, we proposed a multiple description distributed wavelet zero tree image coding system for mobile wireless transmission. We provide two innovations to achieve an excellent error resilient capability. First, when MDC is applied to wavelet subband based image coding, it is possible to introduce correlation between the descriptions in each subband. We consider using such a correlation as well as potentially error corrupted description as side information in the decoding to formulate the MDC decoding as a Wyner Ziv decoding problem. If only part of descriptions is lost, however, their correlation information is still available, the proposed Wyner Ziv decoder can recover the description by using the correlation information and the error corrupted description as side information. Secondly, in each description, single bitstream wavelet zero tree coding is very vulnerable to the channel errors. The first bit error may cause the decoder to discard all subsequent bits whether or not the subsequent bits are correctly received. Therefore, we integrate the multiple description scalar quantization (MDSQ) with the multiple wavelet tree image coding method to reduce error propagation. We first group wavelet coefficients into multiple trees according to parent-child relationship and then code them separately by SPIHT algorithm to form multiple bitstreams. Such decomposition is able to reduce error propagation and therefore improve the error correcting capability of Wyner Ziv decoder. Experimental results show that the proposed scheme not only exhibits an excellent error resilient performance but also demonstrates graceful degradation over the packet loss rate.

Interest has increased over the last several years in using different methods for treating sewage. The rapid population growth in developing countries (Egypt, for example, with a population of more than 87 millions) has created significant sewage disposal problems. There is therefore a growing need for sewage treatment solutions with low energy requirements and using indigenous materials and skills. Gravel Bed Hydroponics (GBH) as a constructed wetland system for sewage treatment has been proved effective for sewage treatment in several Egyptian villages. The system provided an excellent environment for a wide range of species of ciliates (23 species) and these organisms were potentially very useful as biological indicators for various saprobic conditions. Moreover, the ciliates provided excellent means for estimating the efficiency of the system for sewage purification. Results affirmed the ability of this system to produce high quality effluent with sufficient microbial reduction to enable the production of irrigation quality water.

2007-01-01

Background Increasing severe vegetation fires worldwide has been attributed to both global environmental change and land management practices. However there is little evidence concerning the population health effects of outdoor air pollution derived from biomass fires. Frequent seasonal bushfires near Darwin, Australia provide an opportunity to examine this issue. We examined the relationship between atmospheric particle loadings <10 microns in diameter (PM10), and emergency hospital admissions for cardio-respiratory conditions over the three fire seasons of 2000, 2004 and 2005. In addition we examined the differential impacts on Indigenous Australians, a high risk population subgroup. Methods We conducted a case-crossover analysis of emergency hospital admissions with principal ICD10 diagnosis codes J00–J99 and I00–I99. Conditional logistic regression models were used to calculate odds ratios for admission with 10 μg/m3 rises in PM10. These were adjusted for weekly influenza rates, same day mean temperature and humidity, the mean temperature and humidity of the previous three days, days with rainfall > 5 mm, public holidays and holiday periods. Results PM10 ranged from 6.4 – 70.0 μg/m3 (mean 19.1). 2466 admissions were examined of which 23% were for Indigenous people. There was a positive relationship between PM10 and admissions for all respiratory conditions (OR 1.08 95%CI 0.98–1.18) with a larger magnitude in the Indigenous subpopulation (OR1.17 95% CI 0.98–1.40). While there was no relationship between PM10 and cardiovascular admissions overall, there was a positive association with ischaemic heart disease in Indigenous people, greatest at a lag of 3 days (OR 1.71 95%CI 1.14–2.55). Conclusion PM10 derived from vegetation fires was predominantly associated with respiratory rather than cardiovascular admissions. This outcome is consistent with the few available studies of ambient biomass smoke pollution. Indigenous people appear to be at higher risk of cardio-respiratory hospital admissions associated with exposure to PM10. PMID:17854481

In resource-poor areas, infectious diseases may be important causes of morbidity among individuals infected with the Human T-Lymphotropic Virus type 1 (HTLV-1). We report the clinical associations of HTLV-1 infection among socially disadvantaged Indigenous adults in central Australia. HTLV-1 serological results for Indigenous adults admitted 1(st) January 2000 to 31(st) December 2010 were obtained from the Alice Springs Hospital pathology database. Infections, comorbid conditions and HTLV-1 related diseases were identified using ICD-10 AM discharge morbidity codes. Relevant pathology and imaging results were reviewed. Disease associations, admission rates and risk factors for death were compared according to HTLV-1 serostatus. HTLV-1 western blots were positive for 531 (33.3%) of 1595 Indigenous adults tested. Clinical associations of HTLV-1 infection included bronchiectasis (adjusted Risk Ratio, 1.35; 95% CI, 1.14-1.60), blood stream infections (BSI) with enteric organisms (aRR, 1.36; 95% CI, 1.05-1.77) and admission with strongyloidiasis (aRR 1.38; 95% CI, 1.16-1.64). After adjusting for covariates, HTLV-1 infection remained associated with increased numbers of BSI episodes (adjusted negative binomial regression, coefficient, 0.21; 95% CI, 0.02-0.41) and increased admission numbers with strongyloidiasis (coefficient, 0.563; 95% CI, 0.17-0.95) and respiratory conditions including asthma (coefficient, 0.99; 95% CI, 0.27-1.7), lower respiratory tract infections (coefficient, 0.19; 95% CI, 0.04-0.34) and bronchiectasis (coefficient, 0.60; 95% CI, 0.02-1.18). Two patients were admitted with adult T-cell Leukemia/Lymphoma, four with probable HTLV-1 associated myelopathy and another with infective dermatitis. Independent predictors of mortality included BSI with enteric organisms (aRR 1.78; 95% CI, 1.15-2.74) and bronchiectasis (aRR 2.07; 95% CI, 1.45-2.98). HTLV-1 infection contributes to morbidity among socially disadvantaged Indigenous adults in central Australia. This is largely due to an increased risk of other infections and respiratory disease. The spectrum of HTLV-1 related diseases may vary according to the social circumstances of the affected population.

Malaria, despite being preventable and treatable, continues to be a major public health problem worldwide. The archipelago nation of Cape Verde is in a malaria pre-elimination phase with the highest potential to achieve the target goal of elimination in 2020. Nationwide malaria epidemiological data were obtained from the Cape Verde health information system that includes the individual malaria case notification system from all of the country's health structures. Each case is reported to the surveillance service then to the National Malaria Control Programme, which allowed for compilation in the national malaria case database. The database was analysed to assess the origin of the malaria cases, and incidence was calculated from 2010 to 2016 by sex and age. The health centre, health district and month of diagnosis were evaluated, as well as the sex and the age of the patients, allowing a direct descriptive analysis of national data to provide an up-to-date malaria epidemiological profile of the country. Malaria cases were classified as imported or indigenous, and then, geographical analyses were performed using a unique Geographical National Code with Quantum Geographic Information System 2.16.2 software to map the cases by municipalities. The overall temporal evolution of cases was analysed to assess their monthly and yearly variations from 2010 to 2016. Malaria is unstable in Cape Verde, with inter-annual variation and the majority of infections occurring in adult males (> 20 years). The indigenous cases are restricted to Santiago (96%) and Boavista (4%), while imported cases were recorded in all the nine inhabited islands, originating from neighbouring countries with ongoing malaria transmission; from Lusophone countries (25% from Angola, 25% from Guinea-Bissau), followed by the Republic of Senegal (12%) and Equatorial Guinea (10%). In 2010-2012, more imported (93 cases) than indigenous cases (26 cases) were observed; conversely, in 2013 and 2014, more indigenous cases (49) than imported cases (42) were reported. In 2015 there were 20 imported cases and only 7 indigenous cases. Finally, in 2016, there were 47 indigenous cases and 28 imported cases. The mapping of cases by municipality and country of origin was possible with GIS analyses. While Cape Verde remains on track to achieve malaria elimination by 2020 owing to the reduction of the annual incidence to below 0.1%, the country still records cases of indigenous and imported malaria. However, the indigenous cases are exclusively confined to the Santiago and Boavista islands, while the imported cases recorded nationwide originate only from the African continent, mainly from adult men from the Lusophone countries. Cape Verde needs to target interventions to remove residual foci on Santiago and Boavista islands to reduce malaria lethality to zero and prevent its reintroduction from African countries via transmission across the archipelago. Cape Verde is a good example of local authority's commitment to tackle malaria and work towards its elimination by strengthening the health and surveillance systems.

It is well known that the BER performance of a parallel concatenated turbo-code improves roughly as 1/N, where N is the information block length. However, it has been observed by Benedetto and Montorsi that for most parallel concatenated turbo-codes, the FER performance does not improve monotonically with N. In this report, we study the FER of turbo-codes, and the effects of their concatenation with an outer code. Two methods of concatenation are investigated: across several frames and within each frame. Some asymmetric codes are shown to have excellent FER performance with an information block length of 16384. We also show that the proposed outer coding schemes can improve the BER performance as well by eliminating pathological frames generated by the iterative MAP decoding process.

Traditional medicinal plant species documentation is very crucial in Ethiopia for biodiversity conservation, bioactive chemical extractions and indigenous knowledge retention. Having first observed the inhabitants of Gubalafto District (Northern Ethiopia), the author gathered, recorded, and documented the human traditional medicinal plant species and the associated indigenous knowledge. The study was conducted from February 2013 to January 2015 and used descriptive field survey design. Eighty-four informants were selected from seven study kebeles (sub-districts) in the District through purposive, snowball, and random sampling techniques. Both quantitative and qualitative data were collected through semi-structured interviews, guided field walks, demonstrations, and focus group discussions with the help of guided questions. Data were organized and analyzed by descriptive statistics with SPSS version 20 and Microsoft Office Excel 2007. A total of 135 medicinal plant species within 120 genera and 64 families were documented. Among the species, Ocimum lamiifolium and Rhamnus prinoides scored the highest informant citations and fidelity level value, respectively. In the study area, Asteraceae with 8.1% and herbs with 50.4% plant species were the most used sources for their medicinal uses. A total of 65 ailments were identified as being treated by traditional medicinal plants, among which stomachache (abdominal health problems) was frequently reported. Solanum incanum was reported for the treatment of many of the reported diseases. The leaf, fresh parts, and crushed forms of the medicinal plants were the most preferred in remedy preparations. Oral application was the highest reported administration for 110 preparations. A majority of medicinal plant species existed in the wild without any particular conservation effort. Few informants (about 5%) had only brief notes about the traditional medicinal plants. Ninety percent of the respondents have learned indigenous medicinal plants knowledge from their family members and friends secretly. Orthodox Church schools were found the main place for 65% of healer's indigenous knowledge origin and experiences. Elders, aged between 40 and 84 years, gave detailed descriptions about traditional medicinal plants. Traditional medicinal plants and associated indigenous knowledge are the main systems to maintain human health in Gubalafto District. But minimal conservation measures were recorded in the community. Thus, in-situ and ex-situ conservation practices and sustainable utilization are required in the District.

Clinical audit of rates of maltreatment-related coding before January 2010-December 2011 and after January-December 2012 implementation of a simple coding strategy in 11 English family practices. The strategy included encouraging general practitioners to use, always and as a minimum, the Read code 'Child is cause for concern'. A total of 25,106 children aged 0-18 years were registered with these practices. We also undertook a qualitative service evaluation to investigate barriers to recording. Outcomes were recording of 1) any maltreatment-related codes, 2) child protection proceedings and 3) child was a cause for concern. We found increased recording of any maltreatment-related code (rate ratio 1.4; 95% CI 1.1-1.6), child protection procedures (RR 1.4; 95% CI 1.1-1.6) and cause for concern (RR 2.5; 95% CI 1.8-3.4) after implementation of the coding strategy. Clinicians cited the simplicity of the coding strategy as the most important factor assisting implementation. This simple coding strategy improved clinician's recording of maltreatment-related concerns in a small sample of practices with some 'buy-in'. Further research should investigate how recording can best support the doctor-patient relationship. HOW THIS FITS IN: Recording concerns about child maltreatment, including minor concerns, is recommended by the General Medical Council (GMC) and National Institute for Health and Clinical Excellence (NICE), but there is evidence of substantial under-recording. We describe a simple clinical coding strategy that helped general practitioners to improve recording of maltreatment-related concerns. These improvements could improve case finding of children at risk and information sharing.

The biocompatible film made from wild silkworm cocoon of Attacus atlas is intorduced in this research for anticipation of demand on biocompatible film for regenerative medicine. The wild silkworm cocoon was indigenous Indonesia and was taken from it original location in Indonesia. Protocol for degumming method was obtained in this research by using treatment with NaOH solution at 0.1 M for 1 hour. The film was prepared by grinding the wet degummed fiber until pulp like state was obtained. The mixture was dropped in sequence on the hot ceramic plate with temperature around 60°C. The film thickness can be controlled precisely by using this technique. The film is soaked in alcohor for 1 day for stability testing and the result is found stable. The film is introduced in to COS-1 Cell suspension with previously washed in PBS solution and put in a chamber for biocompatibility testing. The cell are found able to grow and attach in first day observation and dramatically increase after 3 days observation. This is an indicate that the film that is produced from wild silkworm cocon of Attacus atlas has excellent biocompatibility.

The present study evaluated the flavonoid content, antioxidant as well as type II diabetes-related enzyme inhibition activities of ethanolic extract of certain raw and traditionally processed indigenous food ingredients including cereals, legumes, oil seeds, tubers, vegetables and leafy vegetables, which are commonly consumed by vulnerable groups in Kenya. The vegetables exhibited higher flavonoid content (50-703 mg/100 g) when compared with the grains (47-343 mg/100 g). The ethanolic extract of presently studied food ingredients revealed 33-93% DPPH radical scavenging capacity, 486-6,389 mmol Fe(II)/g reducing power, 19-43% α-amylase inhibition activity and 14-68% α-glucosidase inhibition activity. Among the different food-stuffs, the drumstick and amaranth leaves exhibited significantly higher flavonoid content with excellent functional properties. Roasting of grains and cooking of vegetables were found to be suitable processing methods in preserving the functional properties. Hence, such viable processing techniques for respective food samples will be considered in the formulation of functional supplementary foods for vulnerable groups in Kenya.

The membrane bioreactor (MBR) features many advantages, such as its excellent effluent quality and compactness. Moreover, the MBR is well known for its disinfectant capacity. This paper investigates virus removal performance for municipal wastewater using a submerged MBR and the operational conditions affecting the virus removal using indigenous somatic coliphages (SC) as an indicator for viruses. The results revealed that the municipal wastewater acquired by the Qinghe Municipal Wastewater Treatment Plant, Beijing, contained an SC concentration of (2.81+/-1.51)x10(4)PFU ml(-1), which varies seasonally due to spontaneous decay. In the MBR system, the biomass process dominates SC removal. Membrane rejection is an essential supplement of biomass process for SC removal. In this paper, the relative contributions of biomass process and membrane rejection during the start-up and steady operational periods are discussed in detail. The major factors affecting SC removal are biodegradation, membrane pore size, and gel layer formation on the membrane. During long-term experiments, it was demonstrated that high inoculated sludge concentration, long hydraulic retention time, moderate fouling layer, and non-frequent chemical cleaning are favorable for high SC removal in MBR systems.

The current study aimed to investigate the coding sequence, polymorphisms, and expression of the RERG gene in indigenous Chinese goats. cDNA of RERG, obtained through reverse transcription PCR was analyzed using bioinformatic techniques. Polymorphisms in the exon regions of the RERG gene were identified and their associations with growth traits in three varieties of indigenous Chinese goats were investigated. Expression of the RERG gene in three goat breeds of the same age was detected using real-time quantitative PCR. The results revealed that the cDNA of RERG, which contained a complete open reading frame of 20-620 bp, was 629 bp in length. The associated accession numbers in GenBank are JN672576, JQ917222, and JN580309 for the QianBei Ma goat, the GuiZhou white goat, and the GuiZhou black goat, respectively. Four consistent SNP sites were found in the exon regions of the RERG gene for the three goat breeds. mRNA expression of the RERG gene differed between different tissues in adult goats of same age. The highest expression was observed in lung and spleen tissues, while the lowest expression was recorded in thymus gland tissue. In addition, the expression of the RERG gene in the muscle of Guizhou white goat, GuiZhou black goat, and QianBei Ma goat decreased sequentially. Our results lay the foundations for further investigation into the role of the RERG gene in goat growth traits.

Acute rheumatic fever (ARF) is a major cause of morbidity and mortality in developing nations. The objective of this study was to determine the disease burden of ARF among the indigenous and non-indigenous populations of the Northern Mariana Islands. This was a chart review of all pediatric outpatients seen from 1984 to 2006 with ICD-9 codes corresponding to rheumatic fever or any rheumatic cardiac sequelae. The study was set in the only comprehensive inpatient facility and only public pediatric clinic in the Northern Mariana Islands. One hundred fifty-eight cases of ARF were identified. Age at diagnosis ranged from 2.9 to 17.1 years (median 10.6 years). Fever and carditis were the most common presenting findings. The average annualized incidence of ARF was 85.8 per 100,000 person-years for those aged 5-14 years. Sixty-six percent of patients with ARF were of Chamorro or Carolinian ancestry, despite comprising only 39% of the total population, with a combined average annualized incidence of ARF of 167 per 100,000 person-years. This is the first documentation of the incidence of pediatric ARF in the Northern Mariana Islands, delineating the large disease burden in the indigenous and other Pacific Island ethnic groups. Impediments to diagnosis and primary and secondary prevention were identified. The data provide strong support for the need for primary and secondary prevention of ARF.

Analytical Solutions for Radiative Transfer: Implications for Giant Planet Formation by Disk Instability

NASA Astrophysics Data System (ADS)

Boss, Alan P.

2009-03-01

The disk instability mechanism for giant planet formation is based on the formation of clumps in a marginally gravitationally unstable protoplanetary disk, which must lose thermal energy through a combination of convection and radiative cooling if they are to survive and contract to become giant protoplanets. While there is good observational support for forming at least some giant planets by disk instability, the mechanism has become theoretically contentious, with different three-dimensional radiative hydrodynamics codes often yielding different results. Rigorous code testing is required to make further progress. Here we present two new analytical solutions for radiative transfer in spherical coordinates, suitable for testing the code employed in all of the Boss disk instability calculations. The testing shows that the Boss code radiative transfer routines do an excellent job of relaxing to and maintaining the analytical results for the radial temperature and radiative flux profiles for a spherical cloud with high or moderate optical depths, including the transition from optically thick to optically thin regions. These radial test results are independent of whether the Eddington approximation, diffusion approximation, or flux-limited diffusion approximation routines are employed. The Boss code does an equally excellent job of relaxing to and maintaining the analytical results for the vertical (θ) temperature and radiative flux profiles for a disk with a height proportional to the radial distance. These tests strongly support the disk instability mechanism for forming giant planets.

An intercultural birthing house was established in the Highlands of Chiapas, Mexico, as an intervention to reduce maternal mortality among indigenous women. This birth center, known locally as the Casa Materna, is a place where women can come to give birth with their traditional birth attendant. However, three months after opening, no woman had used the birthing house. This study reports on the knowledge, attitudes and practices related to childbirth and use of the Casa Materna from the perspective of the health workers, traditional birth attendants and the program's target population. Structured interviews, in-depth interviews and focus group discussions were conducted with participants from each of these groups. Data was searched for emerging themes and coded. Findings show that the potential success of this program is jeopardized by lack of transport and a strong cultural preference for home births. The paper highlights the importance of community participation in planning and implementing such an intervention and of establishing trust and mutual respect among key actors. Recommendations are provided for moving forward the maternal health agenda of indigenous women in Chiapas.

The Deepwater Horizon oil spill in the Gulf of Mexico resulted in a deep-sea hydrocarbon plume that caused a shift in the indigenous microbial community composition with unknown ecological consequences. Early in the spill history, a bloom of uncultured, thus uncharacterized, members of the Oceanospirillales was previously detected, but their role in oil disposition was unknown. Here our aim was to determine the functional role of the Oceanospirillales and other active members of the indigenous microbial community using deep sequencing of community DNA and RNA, as well as single-cell genomics. Shotgun metagenomic and metatranscriptomic sequencing revealed that genes for motility, chemotaxis and aliphatic hydrocarbon degradation were significantly enriched and expressed in the hydrocarbon plume samples compared with uncontaminated seawater collected from plume depth. In contrast, although genes coding for degradation of more recalcitrant compounds, such as benzene, toluene, ethylbenzene, total xylenes and polycyclic aromatic hydrocarbons, were identified in the metagenomes, they were expressed at low levels, or not at all based on analysis of the metatranscriptomes. Isolation and sequencing of two Oceanospirillales single cells revealed that both cells possessed genes coding for n-alkane and cycloalkane degradation. Specifically, the near-complete pathway for cyclohexane oxidation in the Oceanospirillales single cells was elucidated and supported by both metagenome and metatranscriptome data. The draft genome also included genes for chemotaxis, motility and nutrient acquisition strategies that were also identified in the metagenomes and metatranscriptomes. These data point towards a rapid response of members of the Oceanospirillales to aliphatic hydrocarbons in the deep sea.

A novel construction method of the check matrix for the regular low density parity check (LDPC) code is proposed. The novel regular systematically constructed Gallager (SCG)-LDPC(3969,3720) code with the code rate of 93.7% and the redundancy of 6.69% is constructed. The simulation results show that the net coding gain (NCG) and the distance from the Shannon limit of the novel SCG-LDPC(3969,3720) code can respectively be improved by about 1.93 dB and 0.98 dB at the bit error rate (BER) of 10-8, compared with those of the classic RS(255,239) code in ITU-T G.975 recommendation and the LDPC(32640,30592) code in ITU-T G.975.1 recommendation with the same code rate of 93.7% and the same redundancy of 6.69%. Therefore, the proposed novel regular SCG-LDPC(3969,3720) code has excellent performance, and is more suitable for high-speed long-haul optical transmission systems.

The few studies in Chile assessing the nutritional status of indigenous children show a high prevalence of stunting, excess weight and feeding problems. To compare anthropometric indices in children from indigenous and non indigenous ancestry. School children aged 6 to 8 years old, living in locations with three clear cut levels of social vulnerability were studied. Children were considered indigenous if their last names, as well as those of their parents were of Mapuche origin. Non indigenous were those whose last names were of Spanish origin. Four hundred and fifty indigenous and 684 non indigenous children were studied. Indigenous children from high vulnerability communities were approximately 0.5 z score shorter than those of non indigenous origin. Heights of indigenous and non indigenous children were similar in communities with intermediate and low social vulnerability. The proportion of the lower segment followed the same trend. Weight/height ratios were higher among indigenous children in the three vulnerability levels. Among indigenous children coming from areas of low vulnerability arm circumference was 1 cm broader than that of their non indigenous counterparts. Stunting is prevalent among school children from areas of high socioeconomic vulnerability, mainly rural, and independent from ethnicity. Among indigenous school children overweight and a broader arm circumference are frequent. These results urgently call for located and specific nutrition interventions.

Currently, genome-wide scans for positive selection signatures in commercial breed have been investigated. However, few studies have focused on selection footprints of indigenous breeds. Laiwu pig is an invaluable Chinese indigenous pig breed with extremely high proportion of intramuscular fat (IMF), and an excellent model to detect footprint as the result of natural and artificial selection for fat deposition in muscle. In this study, based on GeneSeek Genomic profiler Porcine HD data, three complementary methods, F ST , iHS (integrated haplotype homozygosity score) and CLR (composite likelihood ratio), were implemented to detect selection signatures in the whole genome of Laiwu pigs. Totally, 175 candidate selected regions were obtained by at least two of the three methods, which covered 43.75 Mb genomic regions and corresponded to 1.79% of the genome sequence. Gene annotation of the selected regions revealed a list of functionally important genes for feed intake and fat deposition, reproduction, and immune response. Especially, in accordance to the phenotypic features of Laiwu pigs, among the candidate genes, we identified several genes, NPY1R, NPY5R, PIK3R1 and JAKMIP1, involved in the actions of two sets of neurons, which are central regulators in maintaining the balance between food intake and energy expenditure. Our results identified a number of regions showing signatures of selection, as well as a list of functionally candidate genes with potential effect on phenotypic traits, especially fat deposition in muscle. Our findings provide insights into the mechanisms of artificial selection of fat deposition and further facilitate follow-up functional studies.

Diabetes in pregnancy carries an increased risk of adverse pregnancy outcomes for both the mother and foetus, but it also provides an excellent early opportunity for intervention in the life course for both mother and baby. In the context of the escalating epidemic of chronic diseases among Indigenous Australians, it is vital that this risk is reduced as early as possible in the life course of the individual. The aims of the PANDORA Study are to: (i) accurately assess rates of diabetes in pregnancy in the Northern Territory (NT) of Australia, where 38% of babies are born to Indigenous mothers; (ii) assess demographic, clinical, biochemical, anthropometric, socioeconomic and early life development factors that may contribute to key maternal and neonatal birth outcomes associated with diabetes in pregnancy; and (iii) monitor relevant post-partum clinical outcomes for both the mothers and their babies. Eligible participants are all NT women with diabetes in pregnancy aged 16 years and over. Information collected includes: standard antenatal clinical information, diagnosis and management of diabetes in pregnancy, socio-economic status, standard clinical birth information (delivery, gestational age, birth weight, adverse antenatal and birth outcomes). Cord blood is collected at the time of delivery and detailed neonatal anthropometric measurements performed within 72 hours of birth. Information will also be collected regarding maternal post-partum glucose tolerance and cardio-metabolic risk factor status, breastfeeding and growth of the baby up to 2 years post-partum in the first instance. This study will accurately document rates and outcomes of diabetes in pregnancy in the NT of Australia, including the high-risk Indigenous Australian population. The results of this study should contribute to policy and clinical guidelines with the goal of reducing the future risk of obesity and diabetes in both mothers and their offspring.

To analyze the characters of malaria epidemic situation in Anhui Province from 1999 to 2013. The incidence and epidemiological data of malaria were retrospectively analyzed by Microsoft Office Excel 2007 and MapInfo Professional 7.0 software. The number of malaria cases changed significantly from 1999 to 2013. In the growing period (1999-2006), the annual malaria incidence increased from 1.32/100 000 to 57.16/ 100 000. The turning point was in 2007 with an annual incidence of 44.69/100 000. From 2008 to 2013 (the reducing period), the annual incidence declined from 22.04/100 000 to 0.32/100 000. All the indigenous cases were vivax malaria. The number of indigenous cases increased from 814 in 1999 to 34,982 in 2006, and then reduced to 3 in 2013, since 2007 the comprehensive measures with an emphasis on the clearance of malaria infection source were implemented. The cases were mainly distributed in the area along the Huaihe River and its north. The epidemic areas moved from the middle to the northern part of the province in the growing period. The incidence in the northern part was falling faster than the middle area in the reducing period. More cases occurred in summer and autumn. Since 2009 the number of imported cases increased from 18 in 2009 to 191 in 2013. During 1999-2010 all the imported cases were falciparum malaria. Since 2011 the Plasmodium parasites were more diverse. The imported cases mainly occurred in the counties with more exported laborers. The epidemic of indigenous malaria has been effectively controlled in Anhui Province, while the imported cases have increased in recent years.

Access to dialysis treatment and the types of treatments employed in Australia differs by Indigenous status. We examined whether dialysis treatment utilisation in Indigenous and non-Indigenous Australians also differs by gender. Using registry data we evaluated 21,832 incident patients (aged ≥18 years) commencing dialysis, 2001-2013. Incidence rates were calculated and multivariate regression modelling used to examine differences in dialysis treatment (modality, location and vascular access creation) by race and gender. Dialysis incidence was consistently higher in Indigenous women compared to all other groups. Compared to Indigenous women, both non-Indigenous women and men were more likely to receive peritoneal dialysis as their initial treatment (non-Indigenous women RR=1.91, 95%CI 1.55-2.35; non-Indigenous men RR=1.73, 1.40-2.14) and were more likely to commence initial treatment at home (non-Indigenous women RR=2.07, 1.66-2.59; non-Indigenous men RR=1.95, 1.56-2.45). All groups were significantly more likely than Indigenous women to receive their final treatment at home. Contemporary dialysis treatment in Australia continues to benefit the dominant non-Indigenous population over the Indigenous population, with non-Indigenous men being particularly advantaged. Implications for Public Health: Treatment guidelines that incorporate a recognition of gender-based preferences and dialysis treatment options specific to Indigenous Australians may assist in addressing this disparity. © 2016 The Authors.

Bandwidth efficient CCSDS coding standard proposals

Costello, Daniel J., Jr.; Perez, Lance C.; Wang, Fu-Quan

1992-01-01

The basic concatenated coding system for the space telemetry channel consists of a Reed-Solomon (RS) outer code, a symbol interleaver/deinterleaver, and a bandwidth efficient trellis inner code. A block diagram of this configuration is shown. The system may operate with or without the outer code and interleaver. In this recommendation, the outer code remains the (255,223) RS code over GF(2 exp 8) with an error correcting capability of t = 16 eight bit symbols. This code's excellent performance and the existence of fast, cost effective, decoders justify its continued use. The purpose of the interleaver/deinterleaver is to distribute burst errors out of the inner decoder over multiple codewords of the outer code. This utilizes the error correcting capability of the outer code more efficiently and reduces the probability of an RS decoder failure. Since the space telemetry channel is not considered bursty, the required interleaving depth is primarily a function of the inner decoding method. A diagram of an interleaver with depth 4 that is compatible with the (255,223) RS code is shown. Specific interleaver requirements are discussed after the inner code recommendations.

Research on Indigenous Elders: From Positivistic to Decolonizing Methodologies

Although indigenous peoples have lower life expectancies than the social majority populations in their countries, increasing numbers of indigenous people are living into old age. Research on indigenous elders is informed by a number of research traditions. Researchers have mined existing data sets to compare characteristics of indigenous populations with non-indigenous groups, and these findings have revealed significant disparities experienced by indigenous elders. Some investigators have attempted to validate standardized research tools for use in indigenous populations. Findings from these studies have furthered our knowledge about indigenous elders and have highlighted the ways in which tools may need to be adapted to better fit indigenous views of the constructs being measured. Qualitative approaches are popular, as they allow indigenous elders to tell their stories and challenge non-indigenous investigators to acknowledge values and worldviews different from their own. Recently, efforts have extended to participatory and decolonizing research methods, which aim to empower indigenous elders as researchers. Research approaches are discussed in light of the negative experiences many indigenous peoples have had with Eurocentric research. Acknowledgment of historical trauma, life-course perspectives, phenomenology, and critical gerontology should frame future research with, rather than on, indigenous elders. PMID:23841952

A new two-dimensional computer code was developed to analyze the viscous flow around unconventional airfoils at various Mach numbers and angles of attack. The Navier-Stokes equations are solved using an implicit, upwind, finite-volume scheme. Both laminar and turbulent flows can be computed. A new nonequilibrium turbulence closure model was developed for computing turbulent flows. This two-layer eddy viscosity model was motivated by the success of the Johnson-King model in separated flow regions. The influence of history effects are described by an ordinary differential equation developed from the turbulent kinetic energy equation. The performance of the present code was evaluated by solving the flow around three airfoils using the Reynolds time-averaged Navier-Stokes equations. Excellent results were obtained for both attached and separated flows about the NACA 0012 airfoil, the RAE 2822 airfoil, and the Integrated Technology A 153W airfoil. Based on the comparison of the numerical solutions with the available experimental data, it is concluded that the present code in conjunction with the new nonequilibrium turbulence model gives excellent results.

The risk factors for peripheral artery disease (PAD) are more common in Indigenous than non-Indigenous Australians, however the presentation and outcome of PAD in Indigenous Australians has not been previously investigated. The aim of this prospective cohort study was to compare the presenting characteristics and clinical outcome of Indigenous and non-Indigenous Australians with PAD. PAD patients were prospectively recruited and followed-up since 2003 from an outpatient vascular clinic in Townsville, Australia. Presenting symptoms and risk factors in Indigenous and non-Indigenous patients were compared using Pearson's χ2 test and Mann Whitney U test. Kaplan Meier survival analysis and Cox proportional hazard analysis were used to compare the incidence of myocardial infarction (MI), stroke or death (major cardiovascular events) among Indigenous and non-Indigenous patients. Four hundred and one PAD patients were recruited, of which 16 were Indigenous and 385 were non-Indigenous Australians. Indigenous Australians were younger at entry (median age 63.3 [54.7-67.8] vs 69.6 [63.3-75.4]), more commonly current smokers (56.3% vs 31.4%), and more frequently had insulin-treated diabetes (18.8% vs 5.2%). During a median follow-up of 2.5 years, five and 45 major cardiovascular events were recorded amongst Indigenous and non-Indigenous Australians, respectively. Indigenous Australians were at ~ 5-fold greater risk of major cardiovascular events (adjusted hazard ratio 4.72 [95% confidence intervals 1.41-15.78], p = 0.012) compared to non-Indigenous Australians. These findings suggest that Indigenous Australians with PAD present at a younger age, have higher rates of smoking and insulin-treated diabetes, and poorer clinical outcomes compared to non-Indigenous Australians.

Background Systematic evidence on the patterns of health deprivation among indigenous peoples remains scant in developing countries. We investigate the inequalities in mortality and substance use between indigenous and non-indigenous, and within indigenous, groups in India, with an aim to establishing the relative contribution of socioeconomic status in generating health inequalities. Methods and Findings Cross-sectional population-based data were obtained from the 1998–1999 Indian National Family Health Survey. Mortality, smoking, chewing tobacco use, and alcohol use were four separate binary outcomes in our analysis. Indigenous status in the context of India was operationalized through the Indian government category of scheduled tribes, or Adivasis, which refers to people living in tribal communities characterized by distinctive social, cultural, historical, and geographical circumstances. Indigenous groups experience excess mortality compared to non-indigenous groups, even after adjusting for economic standard of living (odds ratio 1.22; 95% confidence interval 1.13–1.30). They are also more likely to smoke and (especially) drink alcohol, but the prevalence of chewing tobacco is not substantially different between indigenous and non-indigenous groups. There are substantial health variations within indigenous groups, such that indigenous peoples in the bottom quintile of the indigenous-peoples-specific standard of living index have an odds ratio for mortality of 1.61 (95% confidence interval 1.33–1.95) compared to indigenous peoples in the top fifth of the wealth distribution. Smoking, drinking alcohol, and chewing tobacco also show graded associations with socioeconomic status within indigenous groups. Conclusions Socioeconomic status differentials substantially account for the health inequalities between indigenous and non-indigenous groups in India. However, a strong socioeconomic gradient in health is also evident within indigenous populations, reiterating the overall importance of socioeconomic status for reducing population-level health disparities, regardless of indigeneity.

In Chile, indigenous and non-indigenous schoolchildren have the same stature when they begin school but indigenous adults are shorter, indicating the importance of analyzing growth during puberty. The aim of this study was to compare the growth of indigenous and non-indigenous girls during the 36 months after menarche in Chile's Araucanía Region. A concurrent cohort study was conducted to compare growth in the two ethnic groups, which were comprised of 114 indigenous and 126 non-indigenous girls who recently experienced menarche and were randomly selected. Height was measured at menarche and at 6, 12, 18, 24 and 36 months post-menarche. General linear models were used to analyze growth and a generalized estimating equation model was used to compare height at 36 months post-menarche. At menarche, the Z-score of height/age was less for indigenous than non-indigenous girls (-0.01 vs. -0.61, p < 0.001). Indigenous girls grew at a slower rate than non-indigenous girls (6.5 vs. 7.2 cm, p = 0.02), and height at 36-months post-menarche reached -0.82 vs. -0.35 cm (p <0.001). In an adjusted model at 36 months post-menarche, indigenous girls were 1.6 cm shorter than non-indigenous girls (95% confidence interval: -3.13 to -0.04). The height of indigenous girls at menarche was lower than that of non-indigenous girls and they subsequently grew less, maintaining the gap between the two groups. At the end of the follow-up period, the indigenous girls were shorter than their non-indigenous peers.

Evidence is emerging of the benefits to students of providing continuity of midwifery care as a learning strategy in midwifery education, however little is known about the value of this strategy for midwifery students. To explore Indigenous students' perceptions of providing continuity of midwifery care to Indigenous women whilst undertaking a Bachelor of Midwifery. Indigenous Bachelor of Midwifery students' experiences of providing continuity of midwifery care to Indigenous childbearing women were explored within an Indigenous research approach using a narrative inquiry framework. Participants were three Indigenous midwifery students who provided continuity of care to Indigenous women. Three interconnected themes; facilitating connection, being connected, and journeying with the woman. These themes contribute to the overarching finding that the experience of providing continuity of care for Indigenous women creates a sense of personal affirmation, purpose and a validation of cultural identity in Indigenous students. Midwifery philosophy aligns strongly with the Indigenous health philosophy and this provides a learning platform for Indigenous student midwives. Privileging Indigenous culture within midwifery education programs assists students develop a sense of purpose and affirms them in their emerging professional role and within their community. The findings from this study illustrate the demand for, and pertinence of, continuity of care midwifery experiences with Indigenous women as fundamental to increasing the Indigenous midwifery workforce in Australia. Australian universities should provide this experience for Indigenous student midwives. Copyright © 2016 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Introduction In resource-poor areas, infectious diseases may be important causes of morbidity among individuals infected with the Human T-Lymphotropic Virus type 1 (HTLV-1). We report the clinical associations of HTLV-1 infection among socially disadvantaged Indigenous adults in central Australia. Methodology and Principal Findings HTLV-1 serological results for Indigenous adults admitted 1st January 2000 to 31st December 2010 were obtained from the Alice Springs Hospital pathology database. Infections, comorbid conditions and HTLV-1 related diseases were identified using ICD-10 AM discharge morbidity codes. Relevant pathology and imaging results were reviewed. Disease associations, admission rates and risk factors for death were compared according to HTLV-1 serostatus. HTLV-1 western blots were positive for 531 (33.3%) of 1595 Indigenous adults tested. Clinical associations of HTLV-1 infection included bronchiectasis (adjusted Risk Ratio, 1.35; 95% CI, 1.14–1.60), blood stream infections (BSI) with enteric organisms (aRR, 1.36; 95% CI, 1.05–1.77) and admission with strongyloidiasis (aRR 1.38; 95% CI, 1.16–1.64). After adjusting for covariates, HTLV-1 infection remained associated with increased numbers of BSI episodes (adjusted negative binomial regression, coefficient, 0.21; 95% CI, 0.02–0.41) and increased admission numbers with strongyloidiasis (coefficient, 0.563; 95% CI, 0.17–0.95) and respiratory conditions including asthma (coefficient, 0.99; 95% CI, 0.27–1.7), lower respiratory tract infections (coefficient, 0.19; 95% CI, 0.04–0.34) and bronchiectasis (coefficient, 0.60; 95% CI, 0.02–1.18). Two patients were admitted with adult T-cell Leukemia/Lymphoma, four with probable HTLV-1 associated myelopathy and another with infective dermatitis. Independent predictors of mortality included BSI with enteric organisms (aRR 1.78; 95% CI, 1.15–2.74) and bronchiectasis (aRR 2.07; 95% CI, 1.45–2.98). Conclusion HTLV-1 infection contributes to morbidity among socially disadvantaged Indigenous adults in central Australia. This is largely due to an increased risk of other infections and respiratory disease. The spectrum of HTLV-1 related diseases may vary according to the social circumstances of the affected population. PMID:24454973

A Visual Profile of Queensland Indigenous Children.

Little is known about the prevalence of refractive error, binocular vision, and other visual conditions in Australian Indigenous children. This is important given the association of these visual conditions with reduced reading performance in the wider population, which may also contribute to the suboptimal reading performance reported in this population. The aim of this study was to develop a visual profile of Queensland Indigenous children. Vision testing was performed on 595 primary schoolchildren in Queensland, Australia. Vision parameters measured included visual acuity, refractive error, color vision, nearpoint of convergence, horizontal heterophoria, fusional vergence range, accommodative facility, AC/A ratio, visual motor integration, and rapid automatized naming. Near heterophoria, nearpoint of convergence, and near fusional vergence range were used to classify convergence insufficiency (CI). Although refractive error (Indigenous, 10%; non-Indigenous, 16%; p = 0.04) and strabismus (Indigenous, 0%; non-Indigenous, 3%; p = 0.03) were significantly less common in Indigenous children, CI was twice as prevalent (Indigenous, 10%; non-Indigenous, 5%; p = 0.04). Reduced visual information processing skills were more common in Indigenous children (reduced visual motor integration [Indigenous, 28%; non-Indigenous, 16%; p < 0.01] and slower rapid automatized naming [Indigenous, 67%; non-Indigenous, 59%; p = 0.04]). The prevalence of visual impairment (reduced visual acuity) and color vision deficiency was similar between groups. Indigenous children have less refractive error and strabismus than their non-Indigenous peers. However, CI and reduced visual information processing skills were more common in this group. Given that vision screenings primarily target visual acuity assessment and strabismus detection, this is an important finding as many Indigenous children with CI and reduced visual information processing may be missed. Emphasis should be placed on identifying children with CI and reduced visual information processing given the potential effect of these conditions on school performance.

Hing, Nerilee; Breen, Helen; Gordon, Ashley; Russell, Alex

2014-06-01

The gambling activities of minority groups such as Indigenous peoples are usually culturally complex and poorly understood. To redress the scarcity of information and contribute to a better understanding of gambling by Indigenous people, this paper presents quantitative evidence gathered at three Australian Indigenous festivals, online and in several Indigenous communities. With support from Indigenous communities, the study collected and analyzed surveys from 1,259 self-selected Indigenous adults. Approximately 33 % of respondents gambled on card games while 80 % gambled on commercial gambling forms in the previous year. Gambling participation and involvement are high, particularly on electronic gaming machines (EGMs), the favorite and most regular form of gambling. Men are significantly more likely to participate in gambling and to gamble more frequently on EGMs, horse/dog races, sports betting and instant scratch tickets. This elevated participation and frequency of gambling on continuous forms would appear to heighten gambling risks for Indigenous men. This is particularly the case for younger Indigenous men, who are more likely than their older counterparts to gamble on EGMs, table games and poker. While distinct differences between the gambling behaviors of our Indigenous sample and non-Indigenous Australians are apparent, Australian Indigenous behavior appears similar to that of some Indigenous and First Nations populations in other countries. Although this study represents the largest survey of Indigenous Australian gambling ever conducted in New South Wales and Queensland, further research is needed to extend our knowledge of Indigenous gambling and to limit the risks from gambling for Indigenous peoples.

Following the dispersal out of Africa, where hominins evolved in warm environments for millions of years, our species has colonised different climate zones of the world, including high latitudes and cold environments. The extent to which human habitation in (sub-)Arctic regions has been enabled by cultural buffering, short-term acclimatization and genetic adaptations is not clearly understood. Present day indigenous populations of Siberia show a number of phenotypic features, such as increased basal metabolic rate, low serum lipid levels and increased blood pressure that have been attributed to adaptation to the extreme cold climate. In this study we introduce a dataset of 200 individuals from ten indigenous Siberian populations that were genotyped for 730,525 SNPs across the genome to identify genes and non-coding regions that have undergone unusually rapid allele frequency and long-range haplotype homozygosity change in the recent past. At least three distinct population clusters could be identified among the Siberians, each of which showed a number of unique signals of selection. A region on chromosome 11 (chr11:66-69 Mb) contained the largest amount of clustering of significant signals and also the strongest signals in all the different selection tests performed. We present a list of candidate cold adaption genes that showed significant signals of positive selection with our strongest signals associated with genes involved in energy regulation and metabolism (CPT1A, LRP5, THADA) and vascular smooth muscle contraction (PRKG1). By employing a new method that paints phased chromosome chunks by their ancestry we distinguish local Siberian-specific long-range haplotype signals from those introduced by admixture.

Indigenous children experience significantly more dental caries than non-Indigenous children. This study assessed if access to fluoride in the water closed the gap in dental caries between Indigenous and non-Indigenous children. Data from four states and two territories were sourced from the Child Dental Health Survey (CDHS) conducted in 2010. The outcomes were dental caries in the deciduous and permanent dentitions, and the explanatory variables were Indigenous status and access to fluoridated water (≥0.5 mg/L) prior to 2008. Dental caries prevalence and severity for Indigenous and non-Indigenous children, in both dentitions, was lower in fluoridated areas compared to non-fluoridated areas. Among non-Indigenous children, there was a 50.9% difference in mean dmft scores in fluoridated (1.70) compared to non-fluoridated (2.86) areas. The difference between Indigenous children in fluoridated (3.29) compared to non-fluoridated (4.16) areas was 23.4%. Among non-Indigenous children there was a 79.7% difference in the mean DMFT scores in fluoridated (0.68) compared to non-fluoridated (1.58) areas. The difference between Indigenous children in fluoridated (1.59) and non-fluoridated (2.23) areas was 33.5%. Water fluoridation is effective in reducing dental caries, but does not appear to close the gap between non-Indigenous children and Indigenous children. © 2015 Australian Dental Association.

The purpose of this study was to evaluate the caries experience among 6-12-year-old indigenous (Naporunas) and non-indigenous (recent settlers of mixed ethnic origin) schoolchildren, living in the Amazon basin of Ecuador. Cross-sectional data were obtained from 1,449 clinical exams according to the World Health Organization criteria. Nine (7.6%) indigenous and 3 (4.5%) non-indigenous children had no caries experience in their primary dentition at the age of 6. The mean dmft value (SD) among indigenous and non-indigenous children aged 6 was 6.40 (3.36) and 8.36 (3.93), respectively. Sixty-four (54.2%) indigenous and 29 (43.3%) non-indigenous children had no caries experience in their permanent first molars at the age of 6. Only 7 (6.26%) indigenous and 2 (2.60%) non-indigenous children were caries-free at the age of 12. The mean DMFT values (SD) for 12-year-olds were 4.47 (2.85) among indigenous and 5.25 (2.89) among non-indigenous children. Fillings were almost non existent. Caries rates were high among both groups, with untreated carious lesions predominating in all ages. The data of indigenous children suggest adoption of a non-traditional diet. An appropriate oral health response based primarily on prevention and health promotion is needed.

Two indigenous bacterial strains, Bacillus megaterium ETLB-1 (accession no. KC767548) and Pseudomonas plecoglossicida ETLB-3 (accession no. KC767547), isolated from soil contaminated with paper mill effluent, were co-immobilized on corncob cubes to investigate their biodegradation potential against black liquor (BL). Results exhibit conspicuous reduction in color and lignin of BL upto 913.46 Co-Pt and 531.45 mg l(-1), respectively. Reduction in chlorophenols up to 12 mg l(-1) was recorded with highest release of chloride ions, i.e., 1290 mg l(-1). Maximum enzyme activity for lignin peroxidase (LiP), manganese peroxidase (MnP), and laccase (LAC) was recorded as 5.06, 8.13, and 8.23 U ml(-1), respectively, during the treatment. Scanning electron microscopy (SEM) revealed successful immobilization of bacterial strains in porous structures of biomaterial. Gas chromatography/mass spectroscopy (GC/MS) showed formation of certain low molecular weight metabolites such as 4-hydroxy-benzoic acid, 3-hydroxy-4-methoxybenzaldehyde, ferulic acid, and t-cinnamic acid and removal of majority of the compounds (such as teratogenic phthalate derivatives) during the period of treatment. Results demonstrated that the indigenous bacterial consortium possesses excellent decolorization and lignin degradation capability which enables its commercial utilization in effluents treatment system.

Disparities in health perspectives between Indigenous and non-Indigenous populations are major concerns in many of the world's well-developed nations. Indigenous populations are largely less healthy, more prone to chronic diseases, and have an earlier overall mortality than non-Indigenous populations. Low levels of physical activity (PA) contribute to the high levels of disease in Indigenous Australians. Qualitative analysis of structured one-on-one interviews discussing PA in a regional setting. Participants were 12 Indigenous Australian adults, and 12 non-Indigenous Australian adults matched on age, sex, and basketball division. Most participants reported engaging in regular exercise; however, the Indigenous group reported more barriers to PA. These factors included cost, time management and environmental constraints. The physical facilitators identified by our Indigenous sample included social support, intrinsic motivation and role modelling. Findings describe individual and external factors that promote or constraint PA as reported by Indigenous Australian adults. Results indicate that Indigenous people face specific barriers to PA when compared to a non-Indigenous sample. Implications for public health: This study is the first to compare the perspective of Indigenous Australians to a matched group of non-Indigenous Australians and provides useful knowledge to develop public health programs based on culturally sensitive data. © 2017 The Authors.

Introduction There is growing recognition among health researchers and funders that the wider benefits of research such as economic, social and health impacts ought to be assessed and valued alongside academic outputs such as peer-reviewed papers. Research translation needs to increase and the pathways to impact ought to be more transparent. These processes are particularly pertinent to the Indigenous health sector given continued concerns that Indigenous communities are over-researched with little corresponding improvement in health outcomes. This paper describes the research protocol of a mixed methods study to apply FAIT (Framework to Assess the Impact from Translational health research) to the Centre for Research Excellence in Integrated Quality Improvement (CRE-IQI). FAIT will be applied to five selected CRE-IQI Flagship projects to encourage research translation and assess the wider impact of that research. Methods and analysis Phase I will develop a modified programme logic model for each Flagship project including identifying process, output and impact metrics so progress can be monitored. A scoping review will inform potential benefits. In phase II, programme logic models will be updated to account for changes in the research pathways over time. Audit and feedback will be used to encourage research translation and collect evidence of achievement of any process, output and interim impacts. In phase III, three proven methodologies for measuring research impact—Payback, economic assessment and narratives—will be applied. Data on the application of FAIT will be collected and analysed to inform and improve FAIT’s performance. Ethics and dissemination This study is funded by a nationally competitive grant (ID 1078927) from the Australian National Health and Medical Research Council. Ethics approval was obtained from the University of Newcastle’s Human Research Ethics Committee (ID: H-2017–0026). The results from the study will be presented in several peer-reviewed publications, through conference presentations and via social media. PMID:29208619

The influence of indigenous status and community indigenous composition on obesity and diabetes among Mexican adults.

2011-12-01

In many high-income countries, indigenous populations bear a higher burden of obesity and diabetes than non-indigenous populations. Less is known about these patterns in lower- and middle-income countries. We assessed the hypothesis that obesity and diabetes were less prevalent among indigenous than non-indigenous adults in Mexico, home to the largest indigenous population in Latin America. We investigated socioeconomic explanations for differences. In a related line of inquiry, we examine whether adults in communities with higher versus lower percentages of indigenous residents were buffered against these conditions. We assessed whether differences were partially explained by lower development in higher-indigenous communities. Obesity was based on measured height and weight, and diabetes on a diagnosis from a healthcare professional. The analysis for obesity included 19 577 adults aged 20 and older from the Mexican Family Life Survey (2002), a nationally representative survey of Mexican households and communities; for diabetes, we restricted analysis to adults with health insurance. We used multilevel logistic regression to estimate the odds of obesity and diabetes by indigenous status and community percent indigenous. Results suggest that indigenous adults had significantly lower odds of obesity and diabetes than non-indigenous adults. This advantage was not explained by the lower socioeconomic status of indigenous individuals. A higher percentage of indigenous individuals in communities provided protection against obesity, although not for diabetes. Differences for obesity were not accounted for by community development. Findings suggest that an opportunity may exist to prevent disparities in obesity and diabetes from developing by indigenous characteristics in Mexico. Identifying the sources of protective effects of individual and community indigenous characteristics relative to these health conditions should be a priority, given global implications for prevention.

The aim of this study was to compare growth curves of stature in indigenous and non-indigenous children belonging to two levels of poverty and to establish the onset and evolution of the deficit. Children of indigenous and non-indigenous background living in communities of extreme and low poverty in Chile were studied and their height-for-age Z-score from birth until 6 year of age were compared. Mean weight at birth was within normal range, and no differences were found in ethnicity and levels of poverty. Length at birth was below the reference with the exception of the non indigenous newborn from counties of low poverty. Deficit in growth showed an early start, furthermore in indigenous children belonging to the extreme poverty, is from birth and progress through the 18 months. At 72 months the deficit reached -1.1 z scores in the indigenous of the extreme poverty versus -0.7 in the non indigenous group. Children from the low poverty had a Z-score of -0.4 z scores at 72 months without differences between ethnias. Indigenous of the extreme poverty had less accumulative growth while the indigenous of the low poverty areas growth satisfactory without differences with the non indigenous.

The quality of Indigenous identification in administrative health data in Australia: insights from studies using data linkage

PubMed Central

2012-01-01

Background Missing or incorrect Indigenous status in health records hinders monitoring of Indigenous health indicators. Linkage of administrative data has been used to improve the ascertainment of Indigenous status. Data linkage was pioneered in Western Australia (WA) and is now being used in other Australian states. This systematic review appraises peer-reviewed Australian studies that used data linkage to elucidate the impact of under-ascertainment of Indigenous status on health indicators. Methods A PubMed search identified eligible studies that used Australian linked data to interrogate Indigenous identification using more than one identifier and interrogated the impact of the different identifiers on estimation of Indigenous health indicators. Results Eight papers were included, five from WA and three from New South Wales (NSW). The WA papers included a self-identified Indigenous community cohort and showed improved identification in hospital separation data after 2000. In CVD hospitalised patients (2000–05), under-identification was greater in urban residents, older people and socially more advantaged Indigenous people, with varying algorithms giving different estimates of under-count. Age-standardised myocardial infarction incidence rates (2000–2004) increased by about 10%-15% with improved identification. Under-ascertainment of Indigenous identification overestimated secular improvements in life expectancy and mortality whereas correcting infectious disease notifications resulted in lower Indigenous/ non-Indigenous rate ratios. NSW has a history of poor Indigenous identification in administrative data systems, but the NSW papers confirmed the usefulness of data linkage for improving Indigenous identification and the potential for very different estimates of Indigenous disease indicators depending upon the algorithm used for identification. Conclusions Under-identification of Indigenous status must be addressed in health analyses concerning Indigenous health differentials – they cannot be ignored or wished away. This problem can be substantially diminished through data linkage. Under-identification of Indigenous status impacts differently in different disease contexts, generally resulting in under-estimation of absolute and relative Indigenous health indicators, but may perversely overestimate Indigenous rates and differentials in the setting of stigma-associated conditions such as sexually-transmitted and blood-borne virus infections. Under-numeration in Census surveys also needs consideration to address the added problem of denominator undercounts. PMID:23157943

Towards industrial-strength Navier-Stokes codes

In this paper we discuss our experiences with Navier-Stokes (NS) codes using central differencing (CD) and scalar artificial dissipation (SAD). The NS-CDSAD codes have been developed by several researchers. Our results confirm that for typical commercial transport wing and wing/body configurations flying at transonic conditions with all turbulent boundary layers, NS-CDSAD codes, when used with the Johnson-King turbulence model, are capable of computing pressure distributions in excellent agreement with experimental data. However, results are not as good when laminar boundary layers are present. Exhaustive 2-D grid refinement studies supported by detailed analysis suggest that the numerical errors associated with SAD severely contaminate the solution in the laminar portion of the boundary layer. It is left as a challenge to the CFD community to find and fix the problems with Navier-Stokes codes and to produce a NS code which converges reliably and properly captures the laminar portion of the boundary layer on a reasonable grid.

To quantify the independent roles of geography and Indigenous status in explaining disparities in Potentially Preventable Hospital (PPH) admissions between Indigenous and non-Indigenous Australians. Analysis of linked hospital admission data for New South Wales (NSW), Australia, for the period July 1 2003 to June 30 2008. Age-standardised admission rates, and rate ratios adjusted for age, sex and Statistical Local Area (SLA) of residence using multilevel models. PPH diagnoses accounted for 987,604 admissions in NSW over the study period, of which 3.7% were for Indigenous people. The age-standardised PPH admission rate was 76.5 and 27.3 per 1,000 for Indigenous and non-Indigenous people respectively. PPH admission rates in Indigenous people were 2.16 times higher than in non-Indigenous people of the same age group and sex who lived in the same SLA. The largest disparities in PPH admission rates were seen for diabetes complications, chronic obstructive pulmonary disease and rheumatic heart disease. Both rates of PPH admission in Indigenous people, and the disparity in rates between Indigenous than non-Indigenous people, varied significantly by SLA, with greater disparities seen in regional and remote areas than in major cities. Higher rates of PPH admission among Indigenous people are not simply a function of their greater likelihood of living in rural and remote areas. The very considerable geographic variation in the disparity in rates of PPH admission between Indigenous and non-Indigenous people indicates that there is potential to reduce unwarranted variation by characterising outlying areas which contribute the most to this disparity.

Smoking prevalence estimated between 65% and 84% has been reported among the Yolŋu peoples of East Arnhem Land, Northern Territory. We report on findings of an evaluation of the Yaka Ŋarali' Tackling Indigenous Smoking program in East Arnhem Land. Qualitative interviews with Yolŋu (N = 23) and non-Yolŋu (N = 7) informants were conducted in seven communities between June 2014 and September 2015, with the support of Cultural Mentors, in homeland communities throughout East Arnhem Land. The data was coded using NVivo software, analysed line-by-line and categorised by the researcher (MT) under three a priori categories established as evaluation parameters. In addition, the meanings of ŋarali' and Yolŋu cultural obligations to ŋarali' were analysed using an inductive process. Data were coded under three a priori themes: Yolŋu trying to quit smoking (interest in quitting, access to support); the Yaka Ŋarali program (efficacy and recognition); Yolŋu workforce (roles and responsibilities). Yolŋu informants, including Elders and leaders, both smokers and non-smokers uniformly acknowledged the deep cultural and traditional connection with ŋarali' attributing this relationship with its introduction by the Macassans and its subsequent adoption into ceremony. Given the strong cultural and traditional connection to ŋarali', care must be taken to ensure tobacco control measures maintain congruence with local values and expectations. SO WHAT?: Tailored, localised programs, developed in consultation with communities, Elders and leaders are needed to respect and accommodate the tight connection that the Yolŋu have with ŋarali', maintained over hundreds of years. © 2017 Australian Health Promotion Association.

Little is known of the appropriateness of existing gatekeeper suicide prevention programs for Indigenous communities. Despite the high rates of Indigenous suicide in Australia, especially among Indigenous youth, it is unclear how effective existing suicide prevention programs are in providing appropriate management of Indigenous people at risk of suicide. In-depth, semi-structured interviews and focus groups were conducted with Indigenous communities in rural and regional areas of Southern Queensland. Thematic analysis was performed on the gathered information. Existing programs were time-intensive and included content irrelevant to Indigenous people. There was inconsistency in the content and delivery of gatekeeper training. Programs were also not sustainable for rural and regional Indigenous communities. Appropriate programs should be practical, relevant, and sustainable across all Indigenous communities, with a focus on the social, emotional, cultural and spiritual underpinnings of community wellbeing. Programs need to be developed in thorough consultation with Indigenous communities. Indigenous-led suicide intervention training programs are needed to mitigate the increasing rates of suicide experienced by Indigenous peoples living in rural and remote locations.

Population-based registries report 95% 5-year survival for children undergoing surgery for CHD. This study investigated paediatric cardiac surgical outcomes in the Australian indigenous population. All children who underwent cardiac surgery between May, 2008 and August, 2014 were studied. Demographic information including socio-economic status, diagnoses and co-morbidities, and treatment and outcome data were collected at time of surgery and at last follow-up. A total of 1528 children with a mean age 3.4±4.6 years were studied. Among them, 123 (8.1%) children were identified as indigenous, and 52.7% (62) of indigenous patients were in the lowest third of the socio-economic index compared with 28.2% (456) of non-indigenous patients (p⩽0.001). The indigenous sample had a significantly higher Comprehensive Aristotle Complexity score (indigenous 9.4±4.2 versus non-indigenous 8.7±3.9, p=0.04). The probability of having long-term follow-up did not differ between groups (indigenous 93.8% versus non-indigenous 95.6%, p=0.17). No difference was noted in 30-day mortality (indigenous 3.2% versus non-indigenous 1.4%, p=0.13). The 6-year survival for the entire cohort was 95.9%. The Cox survival analysis demonstrated higher 6-year mortality in the indigenous group - indigenous 8.1% versus non-indigenous 5.0%; hazard ratio (HR)=2.1; 95% confidence intervals (CI): 1.1, 4.2; p=0.03. Freedom from surgical re-intervention was 79%, and was not significantly associated with the indigenous status (HR=1.4; 95% CI: 0.9, 1.9; p=0.11). When long-term survival was adjusted for the Comprehensive Aristotle Complexity score, no difference in outcomes between the populations was demonstrated (HR=1.6; 95% CI: 0.8, 3.2; p=0.19). The indigenous population experienced higher late mortality. This apparent relationship is explained by increased patient complexity, which may reflect negative social and environmental factors.

Despite over-representation of Indigenous Australians in sentinel studies of injecting drug use, little is known about relevant patterns of drug use and dependence. This study compares drug dependence and possible contributing factors in Indigenous and non-Indigenous Australians who inject drugs. Respondent-driven sampling was used in major cities and 'peer recruitment' in regional towns of Queensland to obtain a community sample of Indigenous (n = 282) and non-Indigenous (n = 267) injectors. Data are cross sectional. Multinomial models were developed for each group to examine types of dependence on injected drugs (no dependence, methamphetamine-dependent only, opioid-dependent only, dependent on methamphetamine and opioids). Around one-fifth of Indigenous and non-Indigenous injectors were dependent on both methamphetamine and opioids in the previous 12 months. Psychological distress was associated with dual dependence on these drugs for Indigenous [adjusted relative risk (ARR) 4.86, 95% confidence interval (CI) 2.08-11.34] and non-Indigenous (ARR 4.14, 95% CI 1.59-10.78) participants. Unemployment (ARR 8.98, 95% CI 2.25-35.82) and repeated (> once) incarceration as an adult (ARR 3.78, 95% CI 1.43-9.97) were associated with dual dependence for Indigenous participants only. Indigenous participants had high rates of alcohol dependence, except for those dependent on opioids only. The drug dependence patterns of Indigenous and non-Indigenous people who inject drugs were similar, including the proportions dependent on both methamphetamine and opioids. However, for Indigenous injectors, there was a stronger association between drug dependence and contextual factors such as unemployment and incarceration. Expansion of treatment options and community-level programs may be required. [Smirnov A, Kemp R, Ward J, Henderson S, Williams S, Dev A, Najman J M.

2012-01-01

In Queensland, Australia, the incidence of cancer (all cancers combined) is 21% lower for Indigenous people compared with non-Indigenous people but mortality is 36% higher. Support services play an important role in helping cancer patients through their cancer journey. Indigenous cancer patients are likely to face greater unmet supportive care needs and more barriers to accessing cancer care and support. Other barriers include the higher proportion of Indigenous people who live remotely and in regional areas, a known difficulty for access to health services. This study describes the availability of cancer support services in Queensland for Indigenous patients and relevant location. Using a set criteria 121 services were selected from a pre-existing database (n = 344) of cancer services. These services were invited to complete an online questionnaire. ArcGIS (http://www.esri.com/software/arcgis/index.html) was used to map the services' location (using postcode) against Indigenous population by local government area. Services were classified as an 'Indigenous' or 'Indigenous friendly' service using set criteria. Eighty-three services (73.6%) completed the questionnaire. Mapping revealed services are located where there are relatively low percentages of Indigenous people compared with the whole population. No 'Indigenous-specific' services were identified; however, 11 services (13%) were classed 'Indigenous-friendly'. The primary support offered by these services was 'information'. Fewer referrals were received from Indigenous liaison officers compared with other health professionals. Only 8.6% of services reported frequently having contact with an Indigenous organisation; however, 44.6% of services reported that their staff participated in cultural training. Services also identified barriers to access which may exist for Indigenous clientele, including no Indigenous staff and the costs involved in accessing the service, but were unable to address these issues due to restricted staff and funding capacity. Further research into the best models for providing culturally appropriate cancer support services to Indigenous people is essential to ensure Indigenous patients are well supported throughout their cancer journey. Emphasis should be placed on providing support services where a high Indigenous population percentage resides to ensure support is maintained in rural and remote settings. Further efforts should be placed on relationships with Indigenous organisations and mainstream support services and encouraging referral from Indigenous liaison officers.

Parenting may be influenced by ethnicity; marginalization; education; and poverty. A critical but unexamined question is how these factors may interact to compromise or support parenting practices in ethnic minority communities. This analysis examined associations between mothers’ stimulating parenting practices and a range of child-level (age; sex; and cognitive and socio-emotional development); household-level (indigenous ethnicity; poverty; and parental education); and community-level (economic marginalization and majority indigenous population) variables among 1893 children ages 4–18 months in poor; rural communities in Mexico. We also explored modifiers of associations between living in an indigenous community and parenting. Key findings were that stimulating parenting was negatively associated with living in an indigenous community or family self-identification as indigenous (β = −4.25; SE (Standard Error) = 0.98; β = −1.58; SE = 0.83 respectively). However; living in an indigenous community was associated with significantly more stimulating parenting among indigenous families than living in a non-indigenous community (β = 2.96; SE = 1.25). Maternal education was positively associated with stimulating parenting only in indigenous communities; and household crowding was negatively associated with stimulating parenting only in non-indigenous communities. Mothers’ parenting practices were not associated with child sex; father’s residential status; education; or community marginalization. Our findings demonstrate that despite greater community marginalization; living in an indigenous community is protective for stimulating parenting practices of indigenous mothers. PMID:29295595

Despite the importance of estimating population level cancer outcomes, most registries do not collect critical events such as relapse. Attempts to use health administrative data to identify these events have focused on older adults and have been mostly unsuccessful. We developed and tested administrative data-based algorithms in a population-based cohort of adolescents and young adults with cancer. We identified all Ontario adolescents and young adults 15-21 years old diagnosed with leukemia, lymphoma, sarcoma, or testicular cancer between 1992-2012. Chart abstraction determined the end of initial treatment (EOIT) date and subsequent cancer-related events (progression, relapse, second cancer). Linkage to population-based administrative databases identified fee and procedure codes indicating cancer treatment or palliative care. Algorithms determining EOIT based on a time interval free of treatment-associated codes, and new cancer-related events based on billing codes, were compared with chart-abstracted data. The cohort comprised 1404 patients. Time periods free of treatment-associated codes did not validly identify EOIT dates; using subsequent codes to identify new cancer events was thus associated with low sensitivity (56.2%). However, using administrative data codes that occurred after the EOIT date based on chart abstraction, the first cancer-related event was identified with excellent validity (sensitivity, 87.0%; specificity, 93.3%; positive predictive value, 81.5%; negative predictive value, 95.5%). Although administrative data alone did not validly identify cancer-related events, administrative data in combination with chart collected EOIT dates was associated with excellent validity. The collection of EOIT dates by cancer registries would significantly expand the potential of administrative data linkage to assess cancer outcomes.

Scoring of anatomic injury after trauma: AIS 98 versus AIS 90--do the changes affect overall severity assessment?

Although several changes were implemented in the 1998 update of the abbreviated injury scale (AIS 98) versus the previous AIS 90, both are still used worldwide for coding of anatomic injury in trauma. This could possibly invalidate comparisons between systems using different AIS versions. Our aim was to evaluate whether the use of different coding dictionaries affected estimation of Injury Severity Score (ISS), New Injury Severity Score (NISS) and probability of survival (Ps) according to TRISS in a hospital-based trauma registry. In a prospective study including 1654 patients from Ulleval University Hospital, a Norwegian trauma referral centre, patients were coded according to both AIS 98 and AIS 90. Agreement between the classifications of ISS, NISS and Ps according to TRISS methodology was estimated using intraclass correlation coefficients (ICC) with 95% CI. ISS changed for 378 of 1654 patients analysed (22.9%). One hundred and forty seven (8.9%) were coded differently due to different injury descriptions and 369 patients (22.3%) had a change in ISS value in one or more regions due to the different scoring algorithm for skin injuries introduced in AIS 98. This gave a minimal change in mean ISS (14.74 versus 14.54). An ICC value of 0.997 (95% CI 0.9968-0.9974) for ISS indicates excellent agreement between the scoring systems. There were no significant changes in NISS and Ps. There was excellent agreement for the overall population between ISS, NISS and Ps values obtained using AIS 90 and AIS 98 for injury coding. Injury descriptions for hypothermia were re-introduced in the recently published AIS 2005. We support this change as coding differences due to hypothermia were encountered in 4.3% of patients in the present study.

The concept of coding metasurface makes a link between physically metamaterial particles and digital codes, and hence it is possible to perform digital signal processing on the coding metasurface to realize unusual physical phenomena. Here, this study presents to perform Fourier operations on coding metasurfaces and proposes a principle called as scattering-pattern shift using the convolution theorem, which allows steering of the scattering pattern to an arbitrarily predesigned direction. Owing to the constant reflection amplitude of coding particles, the required coding pattern can be simply achieved by the modulus of two coding matrices. This study demonstrates that the scattering patterns that are directly calculated from the coding pattern using the Fourier transform have excellent agreements to the numerical simulations based on realistic coding structures, providing an efficient method in optimizing coding patterns to achieve predesigned scattering beams. The most important advantage of this approach over the previous schemes in producing anomalous single-beam scattering is its flexible and continuous controls to arbitrary directions. This work opens a new route to study metamaterial from a fully digital perspective, predicting the possibility of combining conventional theorems in digital signal processing with the coding metasurface to realize more powerful manipulations of electromagnetic waves.

We present a fully digital procedure of designing reflective coding metasurfaces to shape reflected electromagnetic waves. The design procedure is completely automatic, controlled by a personal computer. In details, the macro coding units of metasurface are automatically divided into several types (e.g. two types for 1-bit coding, four types for 2-bit coding, etc.), and each type of the macro coding units is formed by discretely random arrangement of micro coding units. By combining an optimization algorithm and commercial electromagnetic software, the digital patterns of the macro coding units are optimized to possess constant phase difference for the reflected waves. The apertures of the designed reflective metasurfaces are formed by arranging the macro coding units with certain coding sequence. To experimentally verify the performance, a coding metasurface is fabricated by automatically designing two digital 1-bit unit cells, which are arranged in array to constitute a periodic coding metasurface to generate the required four-beam radiations with specific directions. Two complicated functional metasurfaces with circularly- and elliptically-shaped radiation beams are realized by automatically designing 4-bit macro coding units, showing excellent performance of the automatic designs by software. The proposed method provides a smart tool to realize various functional devices and systems automatically.

To conduct a nationwide survey on the prevalence and causes of vision loss in Indigenous and non-Indigenous Australians. Nationwide, cross-sectional, population-based survey. Indigenous Australians aged 40 years or older and non-Indigenous Australians aged 50 years and older. Multistage random-cluster sampling was used to select 3098 non-Indigenous Australians and 1738 Indigenous Australians from 30 sites across 5 remoteness strata (response rate of 71.5%). Sociodemographic and health data were collected using an interviewer-administered questionnaire. Trained examiners conducted standardized eye examinations, including visual acuity, perimetry, slit-lamp examination, intraocular pressure, and fundus photography. The prevalence and main causes of bilateral presenting vision loss (visual acuity <6/12 in the better eye) were determined, and risk factors were identified. Prevalence and main causes of vision loss. The overall prevalence of vision loss in Australia was 6.6% (95% confidence interval [CI], 5.4-7.8). The prevalence of vision loss was 11.2% (95% CI, 9.5-13.1) in Indigenous Australians and 6.5% (95% CI, 5.3-7.9) in non-Indigenous Australians. Vision loss was 2.8 times more prevalent in Indigenous Australians than in non-Indigenous Australians after age and gender adjustment (17.7%, 95% CI, 14.5-21.0 vs. 6.4%, 95% CI, 5.2-7.6, P < 0.001). In non-Indigenous Australians, the leading causes of vision loss were uncorrected refractive error (61.3%), cataract (13.2%), and age-related macular degeneration (10.3%). In Indigenous Australians, the leading causes of vision loss were uncorrected refractive error (60.8%), cataract (20.1%), and diabetic retinopathy (5.2%). In non-Indigenous Australians, increasing age (odds ratio [OR], 1.72 per decade) and having not had an eye examination within the past year (OR, 1.61) were risk factors for vision loss. Risk factors in Indigenous Australians included older age (OR, 1.61 per decade), remoteness (OR, 2.02), gender (OR, 0.60 for men), and diabetes in combination with never having had an eye examination (OR, 14.47). Vision loss is more prevalent in Indigenous Australians than in non-Indigenous Australians, highlighting that improvements in eye healthcare in Indigenous communities are required. The leading causes of vision loss were uncorrected refractive error and cataract, which are readily treatable. Other countries with Indigenous communities may benefit from conducting similar surveys of Indigenous and non-Indigenous populations. Copyright © 2017 American Academy of Ophthalmology.

This report presents the performance of a steady-state, dual-spool, separate-exhaust turbofan engine, with an interstage turbine burner (ITB) serving as a secondary combustor. The ITB, which is located in the transition duct between the high- and the low-pressure turbines, is a relatively new concept for increasing specific thrust and lowering pollutant emissions in modern jet-engine propulsion. A detailed off-design performance analysis of ITB engines is written in Microsoft(Registered Trademark) Excel (Redmond, Washington) macrocode with Visual Basic Application to calculate engine performances over the entire operating envelope. Several design-point engine cases are pre-selected using a parametric cycle-analysis code developed previously in Microsoft(Registered Trademark) Excel, for off-design analysis. The off-design code calculates engine performances (i.e. thrust and thrust-specific-fuel-consumption) at various flight conditions and throttle settings.

We compare the prevalence of suicidal thoughts and attempts between Indigenous and non-Indigenous males in urban and regional Australia, and examine the extent to which any disparity between Indigenous and non-Indigenous males varies across age groups. We used data from the baseline wave of The Australian Longitudinal Study on Male Health (Ten to Men), a large-scale cohort study of Australian males aged 10-55 years residing in urban and regional areas. Indigenous identification was determined through participants self-reporting as Aboriginal, Torres Strait Islander or both. The survey collected data on suicidal thoughts in the preceding 2 weeks and lifetime suicide attempts. A total of 432 participants (2.7%) identified as Indigenous and 15,425 as non-Indigenous (97.3%). Indigenous males were twice as likely as non-Indigenous males to report recent suicidal thoughts (17.6% vs 9.4%; odds ratio = 2.1, p < 0.001) and more than three times as likely to report a suicide attempt in their lifetime (17.0% vs 5.1%; odds ratio = 3.6; p < 0.001). The prevalence of recent suicidal thoughts did not differ between Indigenous and non-Indigenous males in younger age groups, but a significant gap emerged among men aged 30-39 years and was largest among men aged 40-55 years. Similarly, the prevalence of lifetime suicide attempts did not differ between Indigenous and non-Indigenous males in the 14- to 17-years age group, but a disparity emerged in the 18- to 24-years age group and was even larger among males aged 25 years and older. Our paper presents unique data on suicidal thoughts and attempts among a broad age range of Indigenous and non-Indigenous males. The disparity in the prevalence of suicidal thoughts increased across age groups, which is in contrast to the large disparity between the Indigenous and non-Indigenous suicide rates in younger age groups.

Abstract Objective To quantify the disparity in incidence of hepatitis B between indigenous and non-indigenous people in Australia, and to estimate the potential impact of a hepatitis B immunization programme targeting non-immune indigenous adults. Methods Using national data on persons with newly acquired hepatitis B disease notified between 2005 and 2012, we estimated incident infection rates and rate ratios comparing indigenous and non-indigenous people, with adjustments for underreporting. The potential impact of a hepatitis B immunization programme targeting non-immune indigenous adults was projected using a Markov chain Monte Carlo simulation model. Findings Of the 54 522 persons with hepatitis B disease notified between 1 January 2005 and 31 December 2012, 1953  infections were newly acquired. Acute hepatitis B infection notification rates were significantly higher for indigenous than non-indigenous Australians. The rates per 100 000 population for all ages were 3.6 (156/4 368 511) and 1.1 (1797/168 449 302) for indigenous and non-indigenous people respectively. The rate ratio of age-standardized notifications was 4.0 (95% confidence interval: 3.7–4.3). If 50% of non-immune indigenous adults (20% of all indigenous adults) were vaccinated over a 10-year programme a projected 527–549 new cases of acute hepatitis B would be prevented. Conclusion There continues to be significant health inequity between indigenous and non-indigenous Australians in relation to vaccine-preventable hepatitis B disease. An immunization programme targeting indigenous Australian adults could have considerable impact in terms of cases of acute hepatitis B prevented, with a relatively low number needed to vaccinate to prevent each case.

National cancer survival statistics are available for the total Australian population but not Indigenous Australians, although their cancer mortality rates are known to be higher than those of other Australians. We aimed to validate analysis methods and report cancer survival rates for Indigenous Australians as the basis for regular national reporting. We used national cancer registrations data to calculate all-cancer and site-specific relative survival for Indigenous Australians (compared with non-Indigenous Australians) diagnosed in 2001-2005. Because of limited availability of Indigenous life tables, we validated and used cause-specific survival (rather than relative survival) for proportional hazards regression to analyze time trends and regional variation in all-cancer survival between 1991 and 2005. Survival was lower for Indigenous than non-Indigenous Australians for all cancers combined and for many cancer sites. The excess mortality of Indigenous people with cancer was restricted to the first three years after diagnosis, and greatest in the first year. Survival was lower for rural and remote than urban residents; this disparity was much greater for Indigenous people. Survival improved between 1991 and 2005 for non-Indigenous people (mortality decreased by 28%), but to a much lesser extent for Indigenous people (11%) and only for those in remote areas; cancer survival did not improve for urban Indigenous residents. Cancer survival is lower for Indigenous than other Australians, for all cancers combined and many individual cancer sites, although more accurate recording of Indigenous status by cancer registers is required before the extent of this disadvantage can be known with certainty. Cancer care for Indigenous Australians needs to be considerably improved; cancer diagnosis, treatment, and support services need to be redesigned specifically to be accessible and acceptable to Indigenous people.

Indigenous infants (infants aged under 12 months) have the highest hospital admission and emergency department presentation risks in Australia. However, there have been no recent reports comparing hospital utilisation between Indigenous and non-Indigenous infants. Our primary objective was to use a large prospective population-based linked dataset to assess the risk of all-cause hospital admission and emergency department presentation in Indigenous compared to non-Indigenous infants in Western Australia (WA). Secondary objectives were to assess the effect of socio-economic status (Index of Relative Socio-Economic Disadvantage [IRSD]) on hospital utilisation and to understand the causes of hospital utilisation. There were 3,382 (5.4%) Indigenous and 59,583 (94.6%) non-Indigenous live births in WA from 1 January 2010 to 31 December 2011. Indigenous infants had a greater risk of hospital admission (adjusted odds ratio [aOR] 1.90, 95% confidence interval [95% CI] 1.77-2.04, p = <0.001) and emergency department presentation (aOR 2.15, 95% CI 1.98-2.33, p = <0.001) compared to non-Indigenous infants. Fifty nine percent (59.0%) of admissions in Indigenous children were classified as preventable compared to 31.2% of admissions in non-Indigenous infants (aOR 2.12, 95% CI 1.88-2.39). The risk of hospital admission in the most disadvantaged (IRSD 1) infants in the total cohort (35.7%) was similar to the risk in the least disadvantaged (IRSD 5) infants (30.6%) (aOR 1.04, 95% CI 0.96-1.13, p = 0.356). WA Indigenous infants have much higher hospital utilisation than non Indigenous infants. WA health services should prioritise Indigenous infants regardless of their socio economic status or where they live.

To compare the magnitude of relative oral health inequalities between Indigenous and non-Indigenous persons from Brazil, New Zealand and Australia. Data were from surveys in Brazil (2010), New Zealand (2009) and Australia (2004-06 and 2012). Participants were aged 35-44 years and 65-74 years. Indigenous and non-Indigenous inequalities were estimated by prevalence ratios (PR) and their corresponding 95% confidence intervals (CI), adjusting for sex, age and income. Outcomes included inadequate dentition, untreated dental caries, periodontal disease and the prevalence of "fair" or "poor" self-rated oral health in Australia and New Zealand, and satisfaction with mouth/teeth in Brazil (SROH). Irrespective of country, Indigenous persons had worse oral health than their non-Indigenous counterparts in all indicators. The magnitude of these ratios was greatest among Indigenous and non-Indigenous Australians, who, after adjustments, had 2.77 times the prevalence of untreated dental caries (95% CI 1.76, 4.37), 5.14 times the prevalence of fair/poor SROH (95% CI 2.53, 10.43). Indigenous people had poorer oral health than their non-Indigenous counterparts, regardless of setting. The magnitude of the relative inequalities was greatest among Indigenous Australians for untreated dental decay and poor SROH. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

LDPC-coded MIMO optical communication over the atmospheric turbulence channel using Q-ary pulse-position modulation.

We describe a coded power-efficient transmission scheme based on repetition MIMO principle suitable for communication over the atmospheric turbulence channel, and determine its channel capacity. The proposed scheme employs the Q-ary pulse-position modulation. We further study how to approach the channel capacity limits using low-density parity-check (LDPC) codes. Component LDPC codes are designed using the concept of pairwise-balanced designs. Contrary to the several recent publications, bit-error rates and channel capacities are reported assuming non-ideal photodetection. The atmospheric turbulence channel is modeled using the Gamma-Gamma distribution function due to Al-Habash et al. Excellent bit-error rate performance improvement, over uncoded case, is found.

Leadership as a Personal Journey: An Indigenous Perspective.

PubMed

Doyle, Kerrie; Hungerford, Catherine

2015-05-01

Indigenous Australians have higher levels of mental illness, self-harm, suicide and substance abuse than non-Indigenous Australians, as well as more frequent contact with the criminal justice system. These indices point to the need for strong leadership to support Close the Gap programmes that have now been implemented across Australia. This article considers leadership as a journey of learning for Australian Indigenous leaders. Through the use of story, it is suggested that a situational leadership approach, incorporating the principles of mindfulness, provides the most appropriate framework for Indigenous leaders who work with Indigenous communities. Flexible approaches are needed to meet the needs of diverse Indigenous populations, and address the complex challenges involved, including lateral violence. Such flexibility will enable Indigenous leaders and communities to work together to achieve improvements in the health outcomes, not only for Indigenous Australians, but also for Indigenous populations worldwide.

Tooth decay is related to poverty, measured at individual and neighbourhood levels. It is however uncertain if living in an advantaged neighbourhood reduces tooth decay similarly in Australian Indigenous and non-Indigenous children. This study describes tooth decay by neighbourhood characteristics and Indigenous status, and examines inequalities by Indigenous status. In deciduous dentition the percentage of children with tooth decay and untreated decay decreased on average 26% and 20% respectively in the non-Indigenous sample from poor to affluent neighbourhoods. In Indigenous children tooth decay and untreated decay decreased on average 6% and 8%, respectively, from poor to affluent neighbourhoods. While all children from affluent areas had less tooth decay, the gap between non-Indigenous and Indigenous children remained significant across neighbourhood characteristics. This suggests that both universal and targeted prevention programs should be considered for all Indigenous children irrespective of where they live.

Drawing upon on the literature on Indigenous values to water, water markets and the empirical findings from a survey of 120 Indigenous and non-Indigenous respondents across northern Australia, the paper makes important qualitative and statistical comparisons between Indigenous and non-Indigenous values to water markets. The study is the first comparison of Indigenous and non-Indigenous values to water markets based on the same survey instrument. Key results from Indigenous respondents include: (1) water markets are held to be an acceptable approach to managing water; (2) markets must be carefully designed to protect customary and ecological values; (3) the allocation of water rights need to encompass equity considerations; and (4) water and land rights should not be separated even if this enhances efficiency, as it runs counter to Indigenous holistic values. Overall, the survey results provide the basis for a proposed adaptive decision loop, which allows decision makers to incorporate stakeholder values in water markets.

Indigenous Australian women's colonial sexual intimacies: positioning indigenous women's agency.

PubMed

Sullivan, Corrinne Tayce

2018-04-01

Colonialist views of Indigenous bodies and sexualities continue to affect Indigenous peoples worldwide. For Indigenous Australians, this burden has resulted in repression and oppression of power, sex and desire. Focusing on the sexual intimacies of Indigenous Australian women, this paper provides an account of the dominant Australian historical discourses, finding that Indigenous women were viewed as exotic, erotic, something to be desired, yet simultaneously something to be feared. Our sexualities were described as savage, promiscuous and primitive and we were often viewed as prostitutes with our voices and views constrained by patriarchal and imperial regimes of power. But within this context, Indigenous women fought back through both individual and collective acts of agency. This paper demonstrates how Indigenous Australian women's agency not as a new phenomenon but rather as a position that disrupts the popular discourses of exploitation and victimhood that have been persistently perpetrated against Indigenous women.

Following the summer holidays of 2011, twelve girls returned to school pregnant in one high school in Auckland New Zealand (NZ). A health promotion leaflet that folded into.a small square containing a condom and was dubbed the 'teabag' was distributed to 15-18 year olds prior to the summer holiday of 2012, in order to increase their sexual health knowledge. This paper reports on the evaluation of the teabag from the students' perspective. During the first term of 2013, seventeen students from two high schools who had received the teabag were interviewed. Five were male and twelve female. Most (16) were of Pacific Island or Maori (indigenous New Zealanders) descent. Interviews were digitally recorded, transcribed, coded and categorised concurrently, in accordance with grounded theory methods. Theoretical sampling was employed and students who had perceptions of the teabag, that were consistent with evolving constructions from data, were invited by school nurses to be interviewed by the researchers. Interviews were coded line by line by two researchers and these codes collapsed into seven focussed codes. Further analysis resulted in the codes being subsumed into three main categories. These categories revealed that the teabag was, helpful, appropriate and became a talking point. The grounded theory and basic social process the researchers constructed from data were that the teabag catalysed conversations about sexual health. The teabag was an acceptable and appropriate sexual health promotion tool to disseminate information about sexual health.

In this paper, we first review 2-D MDW code cross correlation equations and table to be improved significantly by using code correlation properties. These codes can be used in the synchronous optical CDMA systems for multi access interference cancellation and maximum suppress the phase induced intensity noise. Low Psr is due to the reduction of interference noise that is induced by the 2-D MDW code PIIN suppression. High data rate causes increases in BER, requires high effective power and severely deteriorates the system performance. The 2-D W/T MDW code has an excellent system performance where the value of PIIN is suppressed as low as possible at the optimum Psr with high data bit rate. The 2-D MDW code shows better tolerance to PIIN in comparison to others with enhanced system performance. We prove by numerical analysis that the PIIN maximally suppressed by MDW code through the minimizing property of cross correlation in comparison to 2-D PDC and 2-D MQC OCDMA code.scheme systems.

The acceptability and feasibility of an intercultural birth center in the highlands of Chiapas, Mexico

PubMed Central

2013-01-01

Background An intercultural birthing house was established in the Highlands of Chiapas, Mexico, as an intervention to reduce maternal mortality among indigenous women. This birth center, known locally as the Casa Materna, is a place where women can come to give birth with their traditional birth attendant. However, three months after opening, no woman had used the birthing house. Methods This study reports on the knowledge, attitudes and practices related to childbirth and use of the Casa Materna from the perspective of the health workers, traditional birth attendants and the program’s target population. Structured interviews, in-depth interviews and focus group discussions were conducted with participants from each of these groups. Data was searched for emerging themes and coded. Results and conclusions Findings show that the potential success of this program is jeopardized by lack of transport and a strong cultural preference for home births. The paper highlights the importance of community participation in planning and implementing such an intervention and of establishing trust and mutual respect among key actors. Recommendations are provided for moving forward the maternal health agenda of indigenous women in Chiapas. PMID:23587122

Indigenous data governance principles assert that Indigenous communities have a right to data that identifies their people or communities, and a right to determine the use of that data in ways that support Indigenous health and self-determination. Indigenous-driven use of the databases held at the Institute for Clinical Evaluative Sciences (ICES) has resulted in ongoing partnerships between ICES and diverse Indigenous organizations and communities. To respond to this emerging and complex landscape, ICES has established a team whose goal is to support the infrastructure for responding to community-initiated research priorities. ICES works closely with Indigenous partners to develop unique data governance agreements and supports processes, which ensure that ICES scientists must work with Indigenous organizations when conducting research that involves Indigenous peoples. © 2018 Longwoods Publishing.

Rehabilitation of segmental defects of maxilla presents a reconstructive challenge to obtain an ideal osseous form and height with adequate soft tissue investment. Though variety of prosthetic and surgical reconstructive options like the use of vascularized and non vascularized bone grafts are available they produce less than optimal results. Bone transport distraction is a reliable procedure in various maxillofacial bony defect reconstruction techniques. We describe herein a technique of maxillary bone transport distraction using an indigenously designed, custom made trifocal transport distractor performed in a post traumatic avulsive defect of the anterior maxilla. Transport distraction was successful for anterior maxillary alveolar bony regeneration, with excellent soft tissue cover and vestibular depth, which also helped close an oroantral/oronasal fistula.

2016-05-01

A novel construction method of quasi-cyclic low-density parity-check (QC-LDPC) codes is proposed based on Chinese remainder theory (CRT). The method can not only increase the code length without reducing the girth, but also greatly enhance the code rate, so it is easy to construct a high-rate code. The simulation results show that at the bit error rate ( BER) of 10-7, the net coding gain ( NCG) of the regular QC-LDPC(4 851, 4 546) code is respectively 2.06 dB, 1.36 dB, 0.53 dB and 0.31 dB more than those of the classic RS(255, 239) code in ITU-T G.975, the LDPC(32 640, 30 592) code in ITU-T G.975.1, the QC-LDPC(3 664, 3 436) code constructed by the improved combining construction method based on CRT and the irregular QC-LDPC(3 843, 3 603) code constructed by the construction method based on the Galois field ( GF( q)) multiplicative group. Furthermore, all these five codes have the same code rate of 0.937. Therefore, the regular QC-LDPC(4 851, 4 546) code constructed by the proposed construction method has excellent error-correction performance, and can be more suitable for optical transmission systems.

The survival inequality faced by Indigenous Australians after a cancer diagnosis is well documented; what is less understood is whether this inequality has changed over time and what this means in terms of the impact a cancer diagnosis has on Indigenous people. Survival information for all patients identified as either Indigenous (n=3168) or non-Indigenous (n=211,615) and diagnosed in Queensland between 1997 and 2012 were obtained from the Queensland Cancer Registry, with mortality followed up to 31st December, 2013. Flexible parametric survival models were used to quantify changes in the cause-specific survival inequalities and the number of lives that might be saved if these inequalities were removed. Among Indigenous cancer patients, the 5-year cause-specific survival (adjusted by age, sex and broad cancer type) increased from 52.9% in 1997-2006 to 58.6% in 2007-2012, while it improved from 61.0% to 64.9% among non-Indigenous patients. This meant that the adjusted 5-year comparative survival ratio (Indigenous: non-Indigenous) increased from 0.87 [0.83-0.88] to 0.89 [0.87-0.93], with similar improvements in the 1-year comparative survival. Using a simulated cohort corresponding to the number and age-distribution of Indigenous people diagnosed with cancer in Queensland each year (n=300), based on the 1997-2006 cohort mortality rates, 35 of the 170 deaths due to cancer (21%) expected within five years of diagnosis were due to the Indigenous: non-Indigenous survival inequality. This percentage was similar when applying 2007-2012 cohort mortality rates (19%; 27 out of 140 deaths). Indigenous people diagnosed with cancer still face a poorer survival outlook than their non-Indigenous counterparts, particularly in the first year after diagnosis. The improving survival outcomes among both Indigenous and non-Indigenous cancer patients, and the decreasing absolute impact of the Indigenous survival disadvantage, should provide increased motivation to continue and enhance current strategies to further reduce the impact of the survival inequalities faced by Indigenous people diagnosed with cancer.

Blood feeding animals face their host's defenses against tissue injury and blood loss while attempting to feed. One adaptation to surmount these barriers involves the evolution of a salivary potion that disarms their host's inflammatory and anti-hemostatic processes. The composition of the peptide moiety of this potion, or sialome (from the Greek sialo=saliva), can be deducted in part by proper interpretation of the blood feeder' sialotranscriptome. In this work we disclose the sialome of the blood feeding adult female Tabanus bromius. Following assembly of over 75 million Illumina reads (101 nt long) 16,683 contigs were obtained from which 4,078 coding sequences were extracted. From these, 320 were assigned as coding for putative secreted proteins. These 320 contigs mapped 85% of the reads. The antigen-5 proteins family was studied in detail, indicating three Tabanus specific clades with and without disintegrin domains, as well as with and without leukotriene binding domains. Defensins were also detailed; a clade of salivary tabanid peptides was found lacking the propeptide domain ending in the KR dipeptide signaling furin cleavage. Novel protein families were also disclosed. Viral transcripts were identified closely matching the Kotonkan virus capsid proteins. Full length Mariner transposases were also identified. A total of 3,043 coding sequences and their protein products were deposited in Genbank. Hyperlinked excel spreadsheets containing the coding sequences and their annotation are available at http://exon.niaid.nih.gov/transcriptome/T_bromius/Tbromius-web.xlsx (hyperlinked excel spreadsheet, 11 MB) and http://exon.niaid.nih.gov/transcriptome/T_bromius/Tbromius-SA.zip (Standalone excel with all local links, 360 MB). These sequences provide for a platform from which further proteomic studies may be designed to identify salivary proteins from T. bromius that are of pharmacological interest or used as immunological markers of host exposure.

To develop a behavioural observation method to simultaneously assess distractors and communication/teamwork during surgical procedures through direct, on-site observations; to establish the reliability of the method for long (>3 h) procedures. Observational categories for an event-based coding system were developed based on expert interviews, observations and a literature review. Using Cohen's κ and the intraclass correlation coefficient, interobserver agreement was assessed for 29 procedures. Agreement was calculated for the entire surgery, and for the 1st hour. In addition, interobserver agreement was assessed between two tired observers and between a tired and a non-tired observer after 3 h of surgery. The observational system has five codes for distractors (door openings, noise distractors, technical distractors, side conversations and interruptions), eight codes for communication/teamwork (case-relevant communication, teaching, leadership, problem solving, case-irrelevant communication, laughter, tension and communication with external visitors) and five contextual codes (incision, last stitch, personnel changes in the sterile team, location changes around the table and incidents). Based on 5-min intervals, Cohen's κ was good to excellent for distractors (0.74-0.98) and for communication/teamwork (0.70-1). Based on frequency counts, intraclass correlation coefficient was excellent for distractors (0.86-0.99) and good to excellent for communication/teamwork (0.45-0.99). After 3 h of surgery, Cohen's κ was 0.78-0.93 for distractors, and 0.79-1 for communication/teamwork. The observational method developed allows a single observer to simultaneously assess distractors and communication/teamwork. Even for long procedures, high interobserver agreement can be achieved. Data collected with this method allow for investigating separate or combined effects of distractions and communication/teamwork on surgical performance and patient outcomes.

2007-09-01

Identifying Indigenous Peoples globally is complex and contested despite there being an estimated 370 million living in 70 countries. The specific context and use of locally relevant and clear definitions or characterizations of Indigenous Peoples is important for recognizing unique health risks Indigenous Peoples face, for understanding local Indigenous health aspirations and for reflecting on the need for culturally disaggregated data to plan meaningful research and health improvement programs. This paper explores perspectives on defining Indigenous Peoples and reflects on challenges in identifying Indigenous Peoples. Literature reviews and Internet searches were conducted, and some key experts were consulted. Pragmatic and political definitions by international institutions, including the United Nations, are presented as well as characterizations of Indigenous Peoples by governments and academic researchers. Assertions that Indigenous Peoples have about definitions of indigeneity are often related to maintenance of cultural integrity and sustainability of lifestyles. Described here are existing definitions and interests served by defining (or leaving undefined) such definitions, why there is no unified definition and implications of "too restrictive" a definition. Selected indigenous identities and dynamics are presented for North America, the Arctic, Australia and New Zealand, Latin America and the Caribbean, Asia and Africa. While health researchers need to understand the Indigenous Peoples with whom they work, ultimately, indigenous groups themselves best define how they wish to be viewed and identified for research purposes.

BACKGROUND: Process Excellence is a value based approach and focuses on standardizing work processes by eliminating the non-value added processes, identify process improving methodologies and maximize capacity and expertise of the staff. AIM AND OBJECTIVES: To Evaluate the utility of Process Excellence Tools in improving Donor Flow Management in a Tertiary care Hospital by studying the current state of donor movement within the blood bank and providing recommendations for eliminating the wait times and to improve the process and workflow. MATERIALS AND METHODS: The work was done in two phases; The First Phase comprised of on-site observations with the help of an expert trained in Process Excellence Methodology who observed and documented various aspects of donor flow, donor turn around time, total staff details and operator process flow. The Second Phase comprised of constitution of a Team to analyse the data collected. The analyzed data along with the recommendations were presented before an expert hospital committee and the management. RESULTS: Our analysis put forward our strengths and identified potential problems. Donor wait time was reduced by 50% after lean due to better donor management with reorganization of the infrastructure of the donor area. Receptionist tracking showed that 62% of the total time the staff wastes in walking and 22% in other non-value added activities. Defining Duties for each staff reduced the time spent by them in non-value added activities. Implementation of the token system, generation of unique identification code for donors and bar code labeling of the tubes and bags are among the other recommendations. CONCLUSION: Process Excellence is not a programme; it's a culture that transforms an organization and improves its Quality and Efficiency through new attitudes, elimination of wastes and reduction in costs.

A model of the Grumman/Navy F-14A aircraft was developed for analyses using the NASA/Grumman Transonic Wing-Body Code. Computations were performed for isolated wing and wing fuselage glove arrangements to determine the extent of aerodynamic interference effects which propagate outward onto the main wing outer panel. Additional studies were conducted using the full potential analysis, FLO 22, to calibrate any inaccuracies that might accrue because of small disturbance code limitations. Comparisons indicate that the NASA/Grumman code provides excellent flow simulations for the range of wing sweep angles and flow conditions that will be of interest for the upcoming F-14 Variable Sweep Flight Transition Experiment.

Effects of development on indigenous dietary pattern: A Nigerian case study.

The traditional foods of indigenous people in Nigeria are known for their cultural symbolism and agricultural biodiversity which contributes to their daily healthy and rich diet. In the early 90s, rapid development of the Federal Capital Territory (FCT) was noted and the resettlement of indigenes to other parts of the region was reported. These changes have facilitated the modification of indigenous diets, as indigenous groups rapidly embraced modern foods and also adopted the food culture of migrant ethnic groups. This has led to a gradual erosion of indigenous diets and traditional food systems in the FCT. This study explored the impact of development on traditional food systems and determined indigenes perception of the modification to their food culture as a result of the development of their land within the FCT. Field survey was carried out in four indigenous communities in the FCT (30 indigenes from each of the four areas) using structured questionnaires, Focus Group Discussions (FGDs) and key informant interviews. Person Chi Square analysis of indigenes socio-economic characteristics revealed significant relationships between gender of indigenes and farm size, Age and farm size, Educational level and farm/herd size. Qualitative analysis of FGDs revealed indigenes opinion on the socio-cultural changes in behaviour and food systems as a result of development. The study also identified indigenous youths as being most influenced by development especially through education, white collar jobs and social interactions with migrant ethnic groups in the FCT. The study recommended that indigenes should be provided with more secure land tenure and "back-to-farm" initiatives should be put in place by the Nigerian government to encourage indigenous youth to engaged more in agriculture.

Principles and guidelines for good practice in Indigenous engagement in water planning

NASA Astrophysics Data System (ADS)

Jackson, Sue; Tan, Poh-Ling; Mooney, Carla; Hoverman, Suzanne; White, Ian

2012-12-01

SummaryIndigenous rights, values and interests relating to water have been identified by Australia's National Water Commission as a national priority area, requiring greater understanding, research attention and government action. Yet Indigenous water values are rarely addressed in water planning, despite objectives in national policy requiring Indigenous participation and the identification of Indigenous social, spiritual and customary values in water plans. Water planners are presently equipped with a very limited number of engagement tools tailored to the water resource management context to redress the historical neglect of Indigenous interests. In an Australian research project focused on water planning, seven participatory planning tools were employed in three Australian case studies with different social and hydrological characteristics to improve the way in which Indigenous values are elicited and incorporated and to enhance the status of Indigenous knowledge in water planning. The results from the two Murray Darling Basin (MDB) case studies reveal the many ways in which Indigenous values have been adversely affected by recent water resource developments and concomitant water scarcity. In the third case on the Tiwi Islands in the Northern Territory, where land title to the entire water planning area is vested in Indigenous traditional owners, methods were refined to ensure engagement and generate capacity to manage the development of a solely Indigenous-owned, first-generation Water Management Strategy, in collaboration with a range of stakeholders. This paper describes the needs and aspirations of Indigenous people, the engagement strategies employed to elicit Indigenous knowledge, assess Indigenous values, and incorporate the results into three developing water plans. In addition, it outlines a set of general principles to guide water planning in other regions and thereby to improve Indigenous access to water.

The author has identified the following significant results. As part of the tape reformatting process, a simple coded picture output program was developed. This represents Pixel's radiance level by one of a 47 character set on a nonoverprinting line printer. It not only has aided in locating areas for the reformatting process, but has also formed the foundation for a supervised clustering package. This in turn has led to a simplistic but effective thematic mapping package.

Scientists prefer to have a facile access to the results which may require conversions between data formats. First hand SNP data is often entered in or saved in the MS-Excel format, but this software lacks genetic and epidemiological related functions. A general tool to do basic genetic and epidemiological analysis and data conversion for MS-Excel is needed. Findings The SNP_tools package is prepared as an add-in for MS-Excel. The code is written in Visual Basic for Application, embedded in the Microsoft Office package. This add-in is an easy to use tool for users with basic computer knowledge (and requirements for basic statistical analysis). Conclusion Our implementation for Microsoft Excel 2000-2007 in Microsoft Windows 2000, XP, Vista and Windows 7 beta can handle files in different formats and converts them into other formats.

To examine the differences in the physical health of Indigenous and non-Indigenous patients with severe mental illness (SMI) undergoing psychiatric rehabilitation. An audit of the physical health of patients ( n = 361) in all publicly funded residential rehabilitation programs in Queensland was carried out in late 2014. Data collection focused on clinical and lifestyle factors associated with physical health. The prevalence of smoking, substance use and type 2 diabetes in Indigenous patients was significantly higher than rates found in non-Indigenous patients. Metabolic syndrome was also significantly higher in indigenous patients, with 66% of Indigenous patients compared to 46% of non-Indigenous patients meeting criteria for metabolic syndrome. Patients with SMI in residential rehabilitation programs have poor physical health. Our findings underscore the need for clinicians to develop and evaluate interventions aimed at improving the metabolic profile of those with SMI in residential rehabilitation programs. Historical factors and cultural traditions need to be considered when designing lifestyle interventions for Indigenous patients.

Epidemiology of sexually transmitted infections in global indigenous populations: data availability and gaps.

Minichiello, Victor; Rahman, Saifur; Hussain, Rafat

2013-10-01

Socioeconomic and health disadvantage is widespread within and across indigenous communities in the world, leading to differentials in morbidity and mortality between indigenous and non-indigenous populations. Sexually transmitted infections (STIs), including HIV/AIDS, among indigenous populations are an emerging public health concern. The focus of this paper is on examining the STI epidemiology in indigenous communities in various parts of the world utilizing a range of data sources. Most of the STI research on global indigenous communities has concentrated on developed countries, neglecting more than half the world's indigenous people in the developing countries. This has resulted in major gaps in data at global level for STIs and HIV/AIDS among indigenous populations. Available data show that the prevalence of STIs is increasing among the indigenous communities and in several instances, the rates of these infections are higher than among non-indigenous populations. However, HIV still remains low when compared with the rates of other STIs. The paper argues that there is an urgent need to collect more comprehensive and reliable data at the global level across various indigenous communities. There is also an opportunity to reverse current trends in STIs through innovative, evidence-based and culturally appropriate targeted sexual health programmes.

Aboriginal and Torres Strait Islander Australians (Indigenous Australians) have more than twice the smoking prevalence of non-Indigenous Australians. Anti-smoking campaigns have demonstrated success in the general population but little is known about their impact among Indigenous people. A total of 143 Indigenous and a comparison group of 156 non-Indigenous smokers from South Australia were shown 10 anti-smoking advertisements representing a range of advertisements typically aired in Australia. Participants rated advertisements on a five-point Likert scale assessing factors including message acceptance and personalized effectiveness. On average, Indigenous people rated the mainstream advertisements higher than non-Indigenous people and were more likely to report that they provided new information. Advertisements with strong graphic imagery depicting the health effects of smoking were rated highest by Indigenous smokers. Advertisements featuring real people describing the serious health consequences of smoking received mixed responses. Those featuring an ill person were rated higher by Indigenous people than those featuring the family of the person affected by a smoking-related disease. With limited Indigenous-specific messages available and given the finite resources of most public health campaigns, exposure to mainstream strong graphic and emotive first-person narratives about the health effects of smoking are likely to be highly motivating for Indigenous smokers.

Ethnic Identification and its Consequences for Measuring Inequality in Mexico

PubMed Central

Villarreal, Andrés

2015-01-01

This paper examines ethnic boundary crossing and its impact on estimates of ethnic disparities in children’s outcomes in the specific context of Mexico, a country with the largest indigenous population in the Western hemisphere. The boundary that separates the indigenous and non-indigenous population is known to be extremely fluid as it is based on characteristics that can easily change within a generation such as language use, cultural practices and a subjective sense of belonging. Using data from the Mexican census I examine the ethnic classification of children of indigenous parents. I find that movement across the ethnic boundary depends on which of the two criteria currently recognized by the Mexican census is used. Children of indigenous parents are much less likely to be classified as indigenous according to language proficiency, especially when their parents have higher levels of education. By contrast, when proxy self-identification is used as a criterion, children of indigenous parents are more likely to be classified as indigenous, and greater parental education actually results in higher odds that children will be classified as indigenous. The shift in children’s indigenous classification with parental education is found to strongly affect estimates of educational disparities between indigenous and non-indigenous children.

Factors Influencing the Health Behaviour of Indigenous Australians: Perspectives from Support People

Waterworth, Pippa; Pescud, Melanie; Braham, Rebecca; Dimmock, James; Rosenberg, Michael

2015-01-01

Disparities between the health of Indigenous and non-Indigenous populations continue to be prevalent within Australia. Research suggests that Indigenous people participate in health risk behaviour more often than their non-Indigenous counterparts, and that such behaviour has a substantial impact on health outcomes. Although this would indicate that reducing health risk behaviour may have positive effects on health outcomes, the factors that influence Indigenous health behaviour are still poorly understood. This study aimed to interview people who support Indigenous groups to gain an understanding of their views on the factors influencing health behaviour within Indigenous groups in Western Australia. Twenty nine people participated in the study. The emergent themes were mapped against the social ecological model. The results indicated that: (1) culture, social networks, history, racism, socioeconomic disadvantage, and the psychological distress associated with some of these factors interact to affect health behaviour in a complex manner; (2) the desire to retain cultural identity and distinctiveness may have both positive and negative influence on health risk behaviour; (3) strong social connections to family and kin that is intensified by cultural obligations, appears to affirm and disrupt positive health behaviour; (4) the separation between Indigenous and non-Indigenous social connection/networks that appeared to be fostered by marginalisation and racism may influence the effect of social networks on health behaviour; and (5) communication between Indigenous and non-Indigenous people may be interrupted by distrust between the groups, which reduces the influence of some non-Indigenous sources on the health behaviour of Indigenous people.

Rates of chronic kidney disease (CKD) among Indigenous groups in Australia exceed non-Indigenous rates eight-fold. Using kidney volume as a surrogate for nephron number, we carried out a study to determine if Indigenous neonates have a smaller kidney volume (and thus a reduced nephron number) from birth compared with non-Indigenous neonates. We recruited term and preterm neonates (<32 weeks) at a tertiary care neonatal unit over a 12 months period. Preterm neonates were assessed (renal sonography and renal function measurement) at 32 weeks corrected age (CA) and again at 38 weeks CA when blood pressure was also measured. All term neonates were assessed in the first post-natal week, including renal sonography, renal function and blood pressure measurement. The primary outcome measured was total kidney volume (TKV) and estimated glomerular filtration rate (eGFR) was a secondary outcome. Data was available for 44 preterm (11 Indigenous) and 39 term (13 Indigenous) neonates. TKV of Indigenous neonates was significantly lower at 32 weeks [12.0 (2.0) v. 15.4 (5.1) ml; P=0.03] and 38 weeks CA [18.6 (4.0) v. 22.6 (5.9) ml; P=0.04] respectively. Term Indigenous neonates also had smaller kidney volumes compared with non-Indigenous neonates. Despite a smaller kidney volume (and reduced nephron number), Indigenous neonates did not have a significantly lower eGFR. Indigenous neonates achieve similar eGFRs to Non-Indigenous neonates, presumably through a higher single nephron filtration rate. This places Indigenous neonates at a greater risk of long-term kidney damage later in life.

Background Indigenous infants (infants aged under 12 months) have the highest hospital admission and emergency department presentation risks in Australia. However, there have been no recent reports comparing hospital utilisation between Indigenous and non-Indigenous infants. Methods Our primary objective was to use a large prospective population-based linked dataset to assess the risk of all-cause hospital admission and emergency department presentation in Indigenous compared to non-Indigenous infants in Western Australia (WA). Secondary objectives were to assess the effect of socio-economic status (Index of Relative Socio-Economic Disadvantage [IRSD]) on hospital utilisation and to understand the causes of hospital utilisation. Findings There were 3,382 (5.4%) Indigenous and 59,583 (94.6%) non-Indigenous live births in WA from 1 January 2010 to 31 December 2011. Indigenous infants had a greater risk of hospital admission (adjusted odds ratio [aOR] 1.90, 95% confidence interval [95% CI] 1.77–2.04, p = <0.001) and emergency department presentation (aOR 2.15, 95% CI 1.98–2.33, p = <0.001) compared to non-Indigenous infants. Fifty nine percent (59.0%) of admissions in Indigenous children were classified as preventable compared to 31.2% of admissions in non-Indigenous infants (aOR 2.12, 95% CI 1.88–2.39). The risk of hospital admission in the most disadvantaged (IRSD 1) infants in the total cohort (35.7%) was similar to the risk in the least disadvantaged (IRSD 5) infants (30.6%) (aOR 1.04, 95% CI 0.96–1.13, p = 0.356). Interpretation WA Indigenous infants have much higher hospital utilisation than non Indigenous infants. WA health services should prioritise Indigenous infants regardless of their socio economic status or where they live. PMID:27120331

Sumida Huaman, Elizabeth

2016-12-01

Based on ethnographic research with an Indigenous community in Junín, Peru, and involving over 21 participants, this article explores the link between Indigenous lands, environmental knowledge, cultural practices, and education. Drawing from traditional ecological knowledge and nature-mediated education, Indigenous community spaces as vital learning spaces are highlighted. Through the lens of family and community-scale farming, this article also discusses critical perspectives on Indigenous agricultural traditions, lessons in subsistence farming, food and notions of success for students, and globalisation. Finally, an argument is made for educational development to acknowledge the breadth of Indigenous ecological issues, to prioritize Indigenous lands, languages, and cultural practices, and to support collaborative research that underscores Indigenous epistemologies.

Health of Indigenous people in Africa.

2006-06-10

Our paper is part of a series focusing on Indigenous peoples' health in different world regions. Indigenous peoples worldwide are subject to marginalisation and discrimination, systematically experiencing poorer health than do majority groups. In Africa, poor health in the general population is widely recognised, but the consistently lower health position and social status of Indigenous peoples are rarely noted. Disputed conceptual understandings of indigeneity, a history of discriminatory colonial and post-colonial policies, and non-recognition of Indigenous groups by some governments complicate the situation. We discuss two case studies, of the central African Pygmy peoples and the San of southern Africa, to illustrate recurring issues in Indigenous health in the continent. We make recommendations for the recognition of Indigenous peoples in Africa and improvements needed in the collection of health data and the provision of services. Finally, we argue that wider changes are needed to address the social determinants of Indigenous peoples' health.

Restorative Justice Conferencing: Not a Panacea for the Overrepresentation of Australia's Indigenous Youth in the Criminal Justice System.

PubMed

Little, Simon; Stewart, Anna; Ryan, Nicole

2018-03-01

Restorative justice conferencing is a police diversionary strategy used extensively in Australian jurisdictions to channel young offenders away from formal court processing. Advocates view conferencing as culturally appropriate and a means to reduce the overrepresentation of Indigenous young people because it is rooted in Indigenous justice traditions. However, whether conferencing is effective at reducing recidivism by Indigenous young people compared with non-Indigenous young people remains unknown. We examine this using a longitudinal cohort of youth offenders from Australia. Propensity score matching was used to match Indigenous and non-Indigenous young people at their first conference and examined reoffending outcomes to explore its efficacy at reducing recidivism ( n = 394). Results indicate that, despite statistically controlling for factors related to reoffending, recidivism levels postconference were significantly higher for Indigenous young people. These results suggest that conferencing is unlikely to address the problem of Indigenous overrepresentation within Australia's youth justice system.

An explanatory analysis of economic and health inequality changes among Mexican indigenous people, 2000-2010

2014-01-01

Introduction Mexico faces important problems concerning income and health inequity. Mexico’s national public agenda prioritizes remedying current inequities between its indigenous and non-indigenous population groups. This study explores the changes in social inequalities among Mexico’s indigenous and non-indigenous populations for the time period 2000 to 2010 using routinely collected poverty, welfare and health indicator data. Methods We described changes in socioeconomic indicators (housing condition), poverty (Foster-Greer-Thorbecke and Sen-Shorrocks-Sen indexes), health indicators (childhood stunting and infant mortality) using diverse sources of nationally representative data. Results This analysis provides consistent evidence of disparities in the Mexican indigenous population regarding both basic and crucial developmental indicators. Although developmental indicators have improved among the indigenous population, when we compare indigenous and non-indigenous people, the gap in socio-economic and developmental indicators persists. Conclusions Despite a decade of efforts to promote public programs, poverty persists and is a particular burden for indigenous populations within Mexican society. In light of the results, it would be advisable to review public policy and to specifically target future policy to the needs of the indigenous population. PMID:24576113

It is estimated that there are 370 million indigenous peoples in 90 countries globally. Indigenous peoples generally face substantial disadvantage and poorer health status compared with nonindigenous peoples. Population-level cancer surveillance provides data to set priorities, inform policies, and monitor progress over time. Measuring the cancer burden of vulnerable subpopulations, particularly indigenous peoples, is problematic. There are a number of practical and methodological issues potentially resulting in substantial underestimation of cancer incidence and mortality rates, and biased survival rates, among indigenous peoples. This, in turn, may result in a deprioritization of cancer-related programs and policies among these populations. This commentary describes key issues relating to cancer surveillance among indigenous populations including 1) suboptimal identification of indigenous populations, 2) numerator-denominator bias, 3) problems with data linkage in survival analysis, and 4) statistical analytic considerations. We suggest solutions that can be implemented to strengthen the visibility of indigenous peoples around the world. These include acknowledgment of the central importance of full engagement of indigenous peoples with all data-related processes, encouraging the use of indigenous identifiers in national and regional data sets and mitigation and/or careful assessment of biases inherent in cancer surveillance methods for indigenous peoples.

2012-05-01

The objective was to analyze the relationship between socioeconomic status and age at menarche among indigenous and non-indigenous girls in the Araucanía Region of Chile, controlling for nutritional status and mother's age at menarche. A total of 8,624 randomly selected girls from 168 schools were screened, resulting in the selection of 207 indigenous and 200 non-indigenous girls who had recently experienced menarche. Age at menarche was 149.6 ± 10.7 months in the indigenous group and 146.6 ± 10.8 months in the non-indigenous group. Among the non-indigenous, the analysis showed no significant association between age at menarche and socioeconomic status. In the indigenous group, age at menarche among girls with low socioeconomic status was 5.4 months later than among those with higher socioeconomic status. There were no differences in nutritional status according to socioeconomic level. Obesity was associated with earlier menarche. Menarche occurred earlier than in previous generations. An inverse relationship between socioeconomic status and age at menarche was seen in the indigenous group only; low socioeconomic status was associated with delayed menarche, regardless of nutritional status or mother's age at menarche.

While Indigenous people in Queensland have lower colorectal cancer (CRC) incidence and mortality than the rest of the population, CRC remains the third most frequent cancer among Australian Indigenous people overall. This study aimed to investigate patterns of care and survival between Indigenous and non-Indigenous Australians with CRC. Through a matched-cohort design we compared 80 Indigenous and 85 non-Indigenous people all diagnosed with CRC and treated in Queensland public hospitals during 1998-2004 (frequency matched on age, sex, geographical remoteness). We compared clinical and treatment data (Pearson's chi-square) and all-cause and cancer survival (Cox regression analysis). Indigenous patients with CRC were not significantly more likely to have comorbidity, advanced disease at diagnosis or less treatment than non-Indigenous people. There was also no statistically significant difference in all-cause survival (HR 1.14, 95% CI 0.69, 1.89) or cancer survival (HR 1.01, 95% CI 0.60, 1.69) between the two groups. Similar CRC mortality among Indigenous and other Australians may reflect both the lower incidence and adequate management. Increasing life expectancy and exposures to risk factors suggests that Indigenous people are vulnerable to a growing burden of CRC. Primary prevention and early detection will be of paramount importance to future CRC control among Indigenous Australians. Current CRC management must be maintained and include prevention measures to ensure that predicted increases in CRC burden are minimized. © 2014 Wiley Publishing Asia Pty Ltd.

Indigeneity: global and local.

PubMed

Merlan, Francesca

2009-06-01

The term indigenous, long used to distinguish between those who are "native" and their "others" in specific locales, has also become a term for a geocultural category, presupposing a world collectivity of "indigenous peoples" in contrast to their various "others." Many observers have noted that the stimuli for internationalization of the indigenous category originated principally from particular nation-states-Anglo-American settler colonies and Scandinavia. All, I argue, are relevantly political cultures of liberal democracy and weighty (in different ways) in international institutional affairs. However, international indigeneity has not been supported in any unqualified way by actions taken in the name of several nation-states that were among its main points of origin. In fact, staunch resistance to the international indigenous project has recently come from four of them. In 2007, the only four voting countries to reject the main product of international indigenist activity over the past 30 years, the Declaration on the Rights of Indigenous Peoples, were Australia, the United States, Canada, and New Zealand. In these locations, forms of "indigenous relationship" emerged that launched international indigeneity and that strongly influenced international perceptions of what "indigeneity" is and who "indigenous peoples" may be. Some other countries say the model of indigenous relationship that they see represented by the "establishing" set is inapplicable to themselves (but have nonetheless had to take notice of expanding internationalist indigenism). The apparently paradoxical rejection of the draft declaration by the establishing countries is consistent with the combination of enabling and constraining forces that liberal democratic political cultures offer.

Indigenous peoples living with HIV are less likely than non-Indigenous peoples living with HIV to access antiretroviral therapy; however, there is not enough contextual information surrounding this issue. The Indigenous Red Ribbon Storytelling Study was conducted in part to examine how Indigenous peoples living with HIV construct and understand their experiences accessing antiretroviral therapy. Our study design was critical Indigenous qualitative research, using the Behavioral Model of Health Services Use and community-based participatory research approaches. The study was conducted in partnership with Indigenous and non-Indigenous organizations. Study participants were adults from two Canadian cities. The study methods included 20 individual and two Indigenous sharing circle interviews, six participant observation sessions, a short survey and thematic analysis. Accessing antiretroviral therapy within the context of living with a substance use disorder was an overarching theme. Indigenous peoples living with HIV felt they had to choose between living with their active substance use disorder and accessing antiretroviral therapy. They felt misunderstood as a person living with a substance use disorder and often felt coerced into using antiretroviral therapy. Despite these challenges, they persevered as Indigenous peoples living with HIV and a substance use disorder. Further research on antiretroviral therapy access among Indigenous peoples living with HIV and a substance use disorder, particularly from the perspective of health service providers, is needed.

In Australia, Indigenous people experience poor access to health care and the highest rates of morbidity and mortality of any population group. Despite modest improvements in recent years, concerns remains that Indigenous people have been over-researched without corresponding health improvements. Embedding Indigenous leadership, participation, and priorities in health research is an essential strategy for meaningful change for Indigenous people. To centralize Indigenous perspectives in research processes, a transformative shift away from traditional approaches that have benefited researchers and non-Indigenous agendas is required. This shift must involve concomitant strengthening of the research capacity of Indigenous and non-Indigenous researchers and research translators-all must teach and all must learn. However, there is limited evidence about how to strengthen systems and stakeholder capacity to participate in and lead continuous quality improvement (CQI) research in Indigenous primary health care, to the benefit of Indigenous people. This paper describes the collaborative development of, and principles underpinning, a research capacity strengthening (RCS) model in a national Indigenous primary health care CQI research network. The development process identified the need to address power imbalances, cultural contexts, relationships, systems requirements and existing knowledge, skills, and experience of all parties. Taking a strengths-based perspective, we harnessed existing knowledge, skills and experiences; hence our emphasis on capacity "strengthening". New insights are provided into the complex processes of RCS within the context of CQI in Indigenous primary health care.

2015-01-01

Background Indigenous peoples in Canada have higher prevalence of modifiable risk factors for Alzheimer’s disease (AD). The relative importance of these risk factors on AD risk management is poorly understood. Methods Relative risks from literature and prevalence of risk factors from Statistics Canada or the First Nations Regional Health Survey were used to determine projected population attributable risk (PAR) associated with modifiable risk factors for AD (low education and vascular risk factors) among on- and off-reserve Indigenous and non-Indigenous people in Canada using the Levin formula. Results Physical inactivity had the highest PAR for AD among Indigenous and non-Indigenous peoples in Canada (32.5% [10.1%–51.1%] and 30.5% [9.2%–48.8%] respectively). The PAR for most modifiable risk factors was higher among Indigenous peoples in Canada, particularly among on-reserve groups. The greatest differences in PAR were for low educational attainment and smoking, which were approximately 10% higher among Indigenous peoples in Canada. The combined PAR for AD for all six modifiable risk factors was 79.6% among on-reserve Indigenous, 74.9% among off-reserve Indigenous, and 67.1% among non-Indigenous peoples in Canada. (All differences significant to p < .001.) Conclusions Modifiable risk factors are responsible for the most AD cases among Indigenous peoples in Canada. Further research is necessary to determine the prevalence of AD and the impact of risk factor modification among Indigenous peoples in Canada. PMID:26495049

To compare the prevalence of undernutrition and anemia in indigenous and non-indigenous children < 5 years of age at the national level, by region and by urban and rural areas, and to evaluate the degree to which the socioeconomic condition of the family predicts the differences. A national probabilistic survey was conducted in Mexico in 1999. Indigenous families were identified as those in which at least one woman 12-49 years of age in the household spoke a native language. The prevalence of undernutrition (stunting, wasting and underweight) and anemia was compared between indigenous and non-indigenous children. Probability ratios (PR) were used to compare prevalences in indigenous and non-indigenous children adjusting for socioeconomic status (SES) of the family and for other covariates. The prevalences of stunting and underweight were greater in indigenous than in non-indigenous children. At the national level and in urban areas the prevalences were three times greater and in rural areas approximately 2 times greater (p < 0.05). No differences were found in the prevalence of wasting (p > 0.05). The prevalence of anemia in indigenous children was one third greater than in non-indigenous children at the national level (p < 0.05) and was between 30 and 60% greater in urban areas and in the regions studied (p < 0.05) but was not statistically significant (p > 0.05) in rural areas. These differences were reduced to about half when adjusting for SES but remained significantly higher in indigenous children (p < 0.05). Indigenous children have higher probabilities of stunting and underweight than non-indigenous children. The differences are larger in urban areas and in higher socioeconomic geographic regions and are explained mostly by socioeconomic factors. The overall difference in the probability of anemia is small, is higher only in urban relative to rural areas, and is explained to a lesser degree by socioeconomic factors. Policy and programs should be designed and implemented to reduce the dramatic differences in nutritional status between indigenous and non-indigenous children in Mexico.

Background Little is known about the impact of comorbidity on cervical cancer survival in Australian women, including whether Indigenous women’s higher prevalence of comorbidity contributes to their lower survival compared to non-Indigenous women. Methods Data for cervical cancers diagnosed in 2003–2012 were extracted from six Australian state-based cancer registries and linked to hospital inpatient records to identify comorbidity diagnoses. Five-year cause-specific and all-cause survival probabilities were estimated using the Kaplan-Meier method. Flexible parametric models were used to estimate excess cause-specific mortality by Charlson comorbidity index score (0,1,2+), for Indigenous women compared to non-Indigenous women. Results Of 4,467 women, Indigenous women (4.4%) compared to non-Indigenous women had more comorbidity at diagnosis (score ≥1: 24.2% vs. 10.0%) and lower five-year cause-specific survival (60.2% vs. 76.6%). Comorbidity was associated with increased cervical cancer mortality for non-Indigenous women, but there was no evidence of such a relationship for Indigenous women. There was an 18% reduction in the Indigenous: non-Indigenous hazard ratio (excess mortality) when comorbidity was included in the model, yet this reduction was not statistically significant. The excess mortality for Indigenous women was only evident among those without comorbidity (Indigenous: non-Indigenous HR 2.5, 95%CI 1.9–3.4), indicating that factors other than those measured in this study are contributing to the differential. In a subgroup of New South Wales women, comorbidity was associated with advanced-stage cancer, which in turn was associated with elevated cervical cancer mortality. Conclusions Survival was lowest for women with comorbidity. However, there wasn’t a clear comorbidity-survival gradient for Indigenous women. Further investigation of potential drivers of the cervical cancer survival differentials is warranted. Impact The results highlight the need for cancer care guidelines and multidisciplinary care that can meet the needs of complex patients. Also, primary and acute care services may need to pay more attention to Indigenous Australian women who may not obviously need it (i.e. those without comorbidity). PMID:29738533

An indigenous approach to explore health-related experiences among Māori parents: the Pukapuka Hauora asthma study

PubMed Central

2013-01-01

Background The prevalence of asthma for Indigenous New Zealand Māori is amongst the highest in the world. Recent evidence shows ethnic differences in asthma symptom prevalence in New Zealand have widened, with asthma symptoms and hospitalisation rates consistently higher for Māori across all age-groups, especially children and adolescents. This paper: outlines our qualitative, longitudinal research exploring the practical issues Māori children and their families face trying to achieve optimum asthma outcomes; details the research methods used within this study; and discusses the process evaluation findings of the features that made this approach successful in engaging and retaining participants in the study. Methods Thirty-two Māori families were recruited using a Kaupapa Māori (Māori way) Research approach. Each participated in a series of four in-depth interviews that were carried out at seasonal intervals over the course of one year. Families also took part in an interviewer-administered questionnaire and participated in a Photovoice exercise. All interviews were digitally recorded, transcribed verbatim and independently coded by two researchers. The research team then conducted the analysis and theme development. The questionnaires were analysed separately, with explanations for findings explored within the qualitative data. Results The methodology produced a 100 percent retention rate of the participating families over the course of the follow-up. This was attributed to the research collaboration, the respectful research relationships established with families, and the families’ judgement that the methods used enabled them to tell their stories. The acceptability of the methodology will add to the validity and trustworthiness of the findings. Conclusion Given the extent and persistence of ethnic disparities in childhood asthma management, it is imperative that an indigenous approach be taken to understanding the core issues facing Māori families. By conducting community-partnership research underpinned by an indigenous methodology, and employing a range of appropriate methods, we have successfully recruited and retained a cohort of Māori families with experiences of childhood asthma. We aim to make their voices heard in order to develop a series of culturally relevant interventions aimed at remediating these disparities. PMID:23497423

A general program was conducted to develop and assess a computational method for predicting the flow properties in a turbofan forced mixed duct. The detail assessment of the resulting computer code is presented. It was found that the code provided excellent predictions of the kinematics of the mixing process throughout the entire length of the mixer nozzle. The thermal mixing process between the hot core and cold fan flows was found to be well represented in the low speed portion of the flowfield.

We developed a new equation of state (EOS) for nanocarbons in the thermodynamic range of high explosives detonation products (up to 50 GPa and 4000 K). This EOS was fitted to an extensive database of thermodynamic properties computed by molecular dynamics simulations of nanodiamonds and nano-onions with the LCBOPII potential. We reproduced the detonation properties of a variety of high explosives with the CARTE thermochemical code, including carbon-poor and carbon-rich explosives, with excellent accuracy.

Owning to the potential in carbon sequestration and other environmental benefits, biochar has been widely used for in-situ environmental remediation. Understanding the biological effects of biochar is essential. The goal of this study was to explore the response of indigenous microbes under the stress of different concentrations of biochar. The results showed that biochar could significantly change physicochemical properties, enzymes activity and microbial community composition depending on biochar concentration and incubation time. When the concentration of biochar was 50 mg kg -1 , the activities of invertase and alkaline phosphatase were obviously inhibited. Meanwhile, bacterial 16S rRNA and fungal 18S rRNA coding gene copies were decreased by 74% and 25%, respectively after 90 days of incubation. Additionally, the bacterial community succession occurred and the relative intensity of dominant species decreased when treated with high concentration of biochar. However, the activity of urease and alkaline phosphatase, as well as bacterial and fungal abundance, were increased when sediment was treated with 10 mg kg -1 biochar. Relationships among physicochemical properties, heavy metals and microbes were analyzed by correlation analysis and redundancy analysis (RDA). Correlations between invertase activity and pH value in the experiment were significantly negative. Redundancy analysis showed physicochemical properties and heavy metals explained 92% of the variation in the bacterial DGGE profiles and organic matter content explained the majority (45%) of the variation. This study indicated that indigenous microbes could be affected by biochar either directly or indirectly via changing the physicochemical properties and heavy metals of sediment.

Following the dispersal out of Africa, where hominins evolved in warm environments for millions of years, our species has colonised different climate zones of the world, including high latitudes and cold environments. The extent to which human habitation in (sub-)Arctic regions has been enabled by cultural buffering, short-term acclimatization and genetic adaptations is not clearly understood. Present day indigenous populations of Siberia show a number of phenotypic features, such as increased basal metabolic rate, low serum lipid levels and increased blood pressure that have been attributed to adaptation to the extreme cold climate. In this study we introduce a dataset of 200 individuals from ten indigenous Siberian populations that were genotyped for 730,525 SNPs across the genome to identify genes and non-coding regions that have undergone unusually rapid allele frequency and long-range haplotype homozygosity change in the recent past. At least three distinct population clusters could be identified among the Siberians, each of which showed a number of unique signals of selection. A region on chromosome 11 (chr11:66–69 Mb) contained the largest amount of clustering of significant signals and also the strongest signals in all the different selection tests performed. We present a list of candidate cold adaption genes that showed significant signals of positive selection with our strongest signals associated with genes involved in energy regulation and metabolism (CPT1A, LRP5, THADA) and vascular smooth muscle contraction (PRKG1). By employing a new method that paints phased chromosome chunks by their ancestry we distinguish local Siberian-specific long-range haplotype signals from those introduced by admixture. PMID:24847810

One in two Indigenous Australian pregnant women smoke, yet little is known about their trajectory of smoking. This study aimed to explore Aboriginal women's narratives from starting smoking through to pregnancy. A female Aboriginal Researcher conducted individual face-to-face interviews with 20 Aboriginal women from New South Wales, Australia. Recruitment, through Aboriginal services and community networks, continued until saturation was reached. Audio-recorded transcripts were independently open coded by two researchers, inductively analysed and reported using a three-dimensional structure of looking backwards, forwards, inwards, outwards and a sense of place, to elucidate the chronology of events, life stages, characters, environments, and turning points of the stories. A chronology emerged from smoking initiation in childhood, coming of age, becoming pregnant, through to attempts at quitting, and relapse post-partum. Several new themes emerged: the role mothers play in women's smoking and quitting; the contribution of nausea to spontaneous quitting; depression as a barrier to quitting; and the hopes of women for their own and their children's future. The epiphany of pregnancy was a key turning point for many - including the interplay of successive pregnancies; and the intensity of expressed regret. Aboriginal women report multiple influences in the progression of early smoking to pregnancy and beyond. Potential opportunities to intervene include: a) childhood, coming of age, pregnancy, post-natal, in-between births; b) key influencers; c) environments, and d) targeting concurrent substance use. Morning sickness appears to be a natural deterrent to continued smoking. Depression, and its relationship to smoking and quitting in Australian Indigenous pregnant women, requires further research.

Reducing perinatal mortality among Indigenous babies in Queensland: should the first priority be better primary health care or better access to hospital care during confinement?

PubMed

Johnston, Trisha; Coory, Michael

2005-05-27

The perinatal mortality rate among Indigenous Australians is still double that of the rest of the community. The aim of our study was to estimate the extent to which increased risk of low birthweight and preterm birth among Indigenous babies in Queensland account for their continuing mortality excess. If a large proportion of excess deaths can be explained by the unfavourable birthweight and gestational age distribution of Indigenous babies, then that would suggest that priority should be given to implementing primary health care interventions to reduce the risk of low birthweight and preterm birth (eg, interventions to reduce maternal smoking or genitourinary infections). Conversely, if only a small proportion is explained by birthweight and gestational age, then other strategies might need to be considered such as improving access to high-quality hospital care around the time of confinement. Population-based, descriptive study of perinatal mortality rates among Indigenous and non-Indigenous babies, in Queensland, stratified by birthweight and gestational age. Indigenous babies are twice as likely to die as their non-Indigenous counterparts (rate ratio1998-2002: 2.01; 95%ci 1.77, 2.28). However, within separate strata of birth weight and gestational age, Indigenous and non-Indigenous rates are similar. The Mantel-Haenszel rate ratio adjusted for birth weight and gestational age was 1.13 (0.99, 1.28). This means that most of the excess mortality in Indigenous babies is largely due to their unfavourable birth weight and gestational-age distributions. If Indigenous babies had the same birth weight and gestational age distribution as their non-Indigenous counterparts, then the relative disparity would be reduced by 87% and 20 fewer Indigenous babies would die in Queensland each year. Our results suggest that Indigenous mothers at high risk of poor outcome (for example those Indigenous mothers in preterm labour) have good access to high quality medical care around the time of confinement. The main reason Indigenous babies have a high risk of death is because they are born too early and too small. Thus, to reduce the relative excess of deaths among Indigenous babies, priority should be given to primary health care initiatives aimed at reducing the prevalence of low birth weight and preterm birth.

In Australia, significant disparity persists in stillbirth rates between Aboriginal and Torres Strait Islander (Indigenous Australian) and non-Indigenous women. Diabetes, hypertension, antepartum haemorrhage and small-for-gestational age (SGA) have been identified as important contributors to higher rates among Indigenous women. The objective of this study was to examine gestational age specific risk of stillbirth associated with these conditions among Indigenous and non-Indigenous women. Retrospective population-based study of all singleton births of at least 20 weeks gestation or at least 400 grams birthweight in Queensland between July 2005 and December 2011 using data from the Queensland Perinatal Data Collection, which is a routinely-maintained database that collects data on all births in Queensland. Multivariate logistic regression was used to calculate adjusted odds ratios (aOR) and 95 % confidence intervals, adjusting for maternal demographic and pregnancy factors. Of 360987 births analysed, 20273 (5.6 %) were to Indigenous women and 340714 (94.4 %) were to non-Indigenous women. Stillbirth rates were 7.9 (95 % CI 6.8-9.2) and 4.1 (95 % CI 3.9-4.3) per 1000 births, respectively. For both Indigenous and non-Indigenous women across most gestational age groups, antepartum haemorrhage, SGA, pre-existing diabetes and pre-existing hypertension were associated with increased risk of stillbirth. There were mixed results for pre-eclampsia and eclampsia and a consistently raised risk of stillbirth was not seen for gestational diabetes. This study highlights gestational age specific stillbirth risk for Indigenous and non-Indigenous women; and disparity in risk at term gestations. Improving access to and utilisation of appropriate and responsive healthcare may help to address disparities in stillbirth risk for Indigenous women.

A compensatory effect of chronic malnutrition that influences excess of weight has been reported. This effect would be more evident in indigenous populations. The aim of this study was to find out the association between ethnic group (mapuche) and body composition in the telarche and menarche of indigenous and non indigenous adolescents. This was a cross sectional design. At the beginning, a screening of 10,121 girls from 168 schools in the Araucania Region, Chile was done. 230 adolescent in telarche (grade II of the development of the mammary gland): 112 indigenous and 118 non indigenous and 239 in menarche (113 indigenous and 126 non indigenous) were identified. Body mass index (BMI), waist circumference (WC), lean mass (LM) and fat mass (FM) were evaluated. BMI, WC and LM were higher in the indigenous adolescent in telarche. For those with menarche, the differences decreased, reaching with higher values for indigenous girls only in BMI and FM (p=0,04 and 0,02, respectively). Belonging to the indigenous group increased the BMI in 0.37 z scores in telarche (95% CI: 0,17-0,58) and 0,44 in menarche (95% CI:0,18-0,70). Being mapuche was also associated to higher WC: 3.33 cm (CI 1,67 - 4,99) in telarche and 3,17 cm (CI 0,73-5,60) in menarche and to higher lean mass only for those adolescents with telarche (1,3 CI: 0,11-2,43) and to fat mass only for those with menarche (2,4 CI: 1,02-3,77). The body composition indicators in indigenous adolescents are of concern and underscores the importance of programs to promote healthy lifestyles that take into account resources from the indigenous communities.

An epidemiological study was performed with 356 children from 0 to 14 years of age in Rondônia State, Amazon, Brazil, during the period 1997-2006. Cases of TB reported to the Notifiable Diseases Surveillance System were divided into indigenous and non-indigenous categories and analyzed according to sex, age group, place of residence, clinical form, diagnostic tests and treatment outcome. A descriptive analysis of cases and hypothesis test (χ²) was carried out to verify if there were differences in the proportions of illness between the groups investigated. A total of 356 TB cases were identified (125 indigenous, 231 non-indigenous) of which 51.4% of the cases were in males. In the indigenous group, 60.8% of the cases presented in children aged 0-4 years old. The incidence mean was much higher among indigenous; in 2001, 1,047.9 cases/100,000 inhabitants were reported in children aged < 5 years. Pulmonary TB was reported in more than 80% of the cases, and in both groups over 70% of the cases were cured. Cultures and histopathological exams were performed on only 10% of the patients. There were 3 cases of TB/HIV co-infection in the non-indigenous group and none in the indigenous group. The case detection rate was classified as insufficient or fair in more than 80% of the indigenous population notifications, revealing that most of the diagnoses were performed based on chest x-ray. The approach used in this study proved useful in demonstrating inequalities in health between indigenous and non-indigenous populations and was superior to the conventional analyses performed by the surveillance services, drawing attention to the need to improve childhood TB diagnosis among the indigenous population.

A multilevel analysis on the relationship between neighbourhood poverty and public hospital utilization: is the high Indigenous morbidity avoidable?

PubMed Central

2011-01-01

Background The estimated life expectancy at birth for Indigenous Australians is 10-11 years less than the general Australian population. The mean family income for Indigenous people is also significantly lower than for non-Indigenous people. In this paper we examine poverty or socioeconomic disadvantage as an explanation for the Indigenous health gap in hospital morbidity in Australia. Methods We utilised a cross-sectional and ecological design using the Northern Territory public hospitalisation data from 1 July 2004 to 30 June 2008 and socio-economic indexes for areas (SEIFA) from the 2006 census. Multilevel logistic regression models were used to estimate odds ratios and confidence intervals. Both total and potentially avoidable hospitalisations were investigated. Results This study indicated that lifting SEIFA scores for family income and education/occupation by two quintile categories for low socio-economic Indigenous groups was sufficient to overcome the excess hospital utilisation among the Indigenous population compared with the non-Indigenous population. The results support a reframing of the Indigenous health gap as being a consequence of poverty and not simplistically of ethnicity. Conclusions Socio-economic disadvantage is a likely explanation for a substantial proportion of the hospital morbidity gap between Indigenous and non-Indigenous populations. Efforts to improve Indigenous health outcomes should recognise poverty as an underlying determinant of the health gap. PMID:21951514

Health-service performance of TB treatment for indigenous and non-indigenous populations in Brazil: a cross-sectional study

PubMed Central

2014-01-01

Background Health-service evaluation studies are fundamental for proposing interventions and ensuring improvements in healthcare quality. The present study assesses the performance of health services for indigenous and non-indigenous populations with regard to tuberculosis (TB) control. Methods Interviews with TB patients who underwent treatment between 2009 and 2011 were conducted using the Primary Care Assessment Tool adapted for TB care in Brazil. Results Primary healthcare (PHC) was the first treatment for most patients at symptom onset, and the diagnoses were typically performed by specialized services. Many patients experienced delayed TB diagnoses that required more than three medical appointments (51% and 47% for indigenous and non-indigenous populations, respectively). Indigenous people received social support, such as basic-needs grocery packages (2.19 ± 1.63 vs. 1.13 ± 0.49 for non-indigenous people, p < 0.01) and home visits from health professionals, with an emphasis on the performance of directly observed treatment strategies (DOT; 4.57 ± 0.89 vs. 1.68 ± 1.04 for non-indigenous people, p < 0.01). Conclusions Regardless of the differences between indigenous and non-indigenous populations, the time needed to receive a TB diagnosis was unsatisfactory for both groups. Furthermore, DOT must be performed with better coverage among non-indigenous patients. PMID:24885134

Indigenous people are the most disadvantaged population within Australia. The Bachelor of Nursing program at a large university in Western Sydney embedded Indigenous health into the undergraduate teaching program. This paper reviews the negative responses received towards course content on evaluation of the Indigenous health unit and explores the predictors for the negative attitudes towards Indigenous Australians. Two surveys were used (baseline and follow-up) to: 1. Determine the main predictors for negative attitudes towards Indigenous people and; 2. Explore students' perceptions of the educational quality of the Indigenous health unit. The surveys allowed collection of socio-demographic, academic data and included the 18 item 'Attitude Toward Indigenous Australians' (ATIA) scale and open-ended responses. Students who were: 1. Overseas born, 2. Enrolment category: International student and; 3. Whose primary source of information about Indigenous Australians were the media and school were significantly more likely to have higher negative attitudes towards Indigenous Australians. Qualitative data revealed some unfavourable comments dismissing the value and educational quality of the content within the Indigenous health unit. Community engagement is paramount to enhancing the student experience. Movement away from media driven 'hype' to an educated perspective is necessary to create an accurate portrayal of the Indigenous community. Crown Copyright © 2015. Published by Elsevier Ltd.

Involving indigenous peoples in protected area management: comparative perspectives from Nepal, Thailand, and China.

PubMed

Nepal, Sanjay K

2002-12-01

Despite over two decades of efforts towards involving indigenous and traditional peoples in protected area management, there are few successful examples. Several international principles and guidelines on indigenous peoples' involvement in protected areas exist. However, because of the lack of evaluation of whether or not these principles and guidelines have been put into practice, there is hardly any information that indicates the actual involvement of indigenous peoples in protected areas. This paper attempts to compare efforts in partnership between indigenous peoples and protected area authority in three Asian countries: Nepal, Thailand, and China. It shows that the involvement of indigenous peoples is more successful where park planning is participatory and where political and socioeconomic reforms are underway. Indigenous peoples are in conflict with park authorities where park management is centralized and nonparticipatory. Unless concrete efforts are made to address livelihood issues of indigenous peoples living in and around protected areas, park management aimed to protect wildlife will rarely succeed. Participatory park management that involves indigenous peoples and that addresses livelihood issues of indigenous communities will ultimately succeed in its efforts toward wildlife conservation.

Lung disease in indigenous children.

PubMed

Chang, A B; Brown, N; Toombs, M; Marsh, R L; Redding, G J

2014-12-01

Children in indigenous populations have substantially higher respiratory morbidity than non-indigenous children. Indigenous children have more frequent respiratory infections that are, more severe and, associated with long-term sequelae. Post-infectious sequelae such as chronic suppurative lung disease and bronchiectasis are especially prevalent among indigenous groups and have lifelong impact on lung function. Also, although estimates of asthma prevalence among indigenous children are similar to non-indigenous groups the morbidity of asthma is higher in indigenous children. To reduce the morbidity of respiratory illness, best-practice medicine is essential in addition to improving socio-economic factors, (eg household crowding), tobacco smoke exposure, and access to health care and illness prevention programs that likely contribute to these issues. Although each indigenous group may have unique health beliefs and interfaces with modern health care, a culturally sensitive and community-based comprehensive care system of preventive and long term care can improve outcomes for all these conditions. This article focuses on common respiratory conditions encountered by indigenous children living in affluent countries where data is available. Crown Copyright © 2014. Published by Elsevier Ltd.

To understand the nature of excellent clinicians at an academic health science center by exploring how and why excellent clinicians achieve high performance. From 2008 to 2010, the authors conducted a qualitative study using a grounded theory approach. Members of the Clinical Advisory Committee in the Department of Pediatrics at the University of Toronto nominated peers whom they saw as excellent clinicians. The authors then conducted in-depth interviews with the most frequently nominated clinicians. They audio-recorded and transcribed the interviews and coded the transcripts to identify emergent themes. From interviews with 13 peer-nominated, excellent clinicians, a model emerged. Dominant themes fell into three categories: (1) core philosophy, (2) deliberate activities, and (3) everyday practice. Excellent clinicians are driven by a core philosophy defined by high intrinsic motivation and passion for patient care and humility. They refine their clinical skills through two deliberate activities-reflective clinical practice and scholarship. Their high performance in everyday practice is characterized by clinical skills and cognitive ability, people skills, engagement, and adaptability. A rich theory emerged explaining how excellent clinicians, driven by a core philosophy and engaged in deliberate activities, achieve high performance in everyday practice. This theory of the nature of excellent clinicians provides a holistic perspective of individual performance, informs medical education, supports faculty career development, and promotes clinical excellence in the culture of academic medicine.

In the Internet of Things a code resolution service provides a discovery mechanism for a requester to obtain the information resources associated with a particular product code immediately. In large scale application scenarios a code resolution service faces some serious issues involving heterogeneity, big data and data ownership. A code resolution service network is required to address these issues. Firstly, a list of requirements for the network architecture and code resolution services is proposed. Secondly, in order to eliminate code resolution conflicts and code resolution overloads, a code structure is presented to create a uniform namespace for code resolution records. Thirdly, we propose a loosely coupled distributed network consisting of heterogeneous, independent; collaborating code resolution services and a SkipNet based code resolution service named SkipNet-OCRS, which not only inherits DHT's advantages, but also supports administrative control and autonomy. For the external behaviors of SkipNet-OCRS, a novel external behavior mode named QRRA mode is proposed to enhance security and reduce requester complexity. For the internal behaviors of SkipNet-OCRS, an improved query algorithm is proposed to increase query efficiency. It is analyzed that integrating SkipNet-OCRS into our resolution service network can meet our proposed requirements. Finally, simulation experiments verify the excellent performance of SkipNet-OCRS.

2009-01-01

The Kansas Geological Survey (KGS) developed a semianalytical solution for slug tests that incorporates the effects of partial penetration, anisotropy, and the presence of variable conductivity well skins. The solution can simulate either confined or unconfined conditions. The original model, written in FORTRAN, has a text-based interface with rigid input requirements and limited output options. We re-created the main routine for the KGS model as a Visual Basic macro that runs in most versions of Microsoft Excel and built a simple-to-use Excel spreadsheet interface that automatically displays the graphical results of the test. A comparison of the output from the original FORTRAN code to that of the new Excel spreadsheet version for three cases produced identical results.

To examine differences in land use and environmental impacts between colonist and indigenous populations in the northern Ecuadorian Amazon, we combined data from household surveys and remotely sensed imagery that was collected from 778 colonist households in 64 colonization sectors, and 499 households from five indigenous groups in 36 communities. Overall, measures of deforestation and forest fragmentation were significantly greater for colonists than indigenous peoples. On average, colonist households had approximately double the area in agriculture and cash crops and 5.5 times the area in pasture as indigenous households. Nevertheless, substantial variation in land-use patterns existed among the five indigenous groups in measures such as cattle ownership and use of hired agricultural labor. These findings support the potential conservation value of indigenous lands while cautioning against uniform policies that homogenize indigenous ethnic groups.

A Community Engaged Dental Curriculum: A Rural Indigenous Outplacement Programme

Abuzar, Menaka A.; Owen, Julie

2016-01-01

Background Indigenous people worldwide suffer from poor oral health as compared to non-Indigenous citizens. One of the approaches to bring about improvement in Indigenous oral health is to enhance the service provision by implementing oral health outplacement programmes. A case study of such a programme for dental students in Australia reports how an educational institution can successfully engage with an Indigenous oral health service to provide learning experiences to the students as well as deliver much needed services to the community. Design and Methods The assessment of this ongoing outplacement programme over the period of 2008-14, based on students’ feedback, highlights some of the key beneficial outcomes. Students agreed that the Indigenous outplacement programme improved their understanding of Indigenous issues (mean ± SD: 4.10±0.8; 5 refers to strongly agree on 5-point scale) and increased the possibility that they will practise in Indigenous health (3.66±1.0). They were pleased with the assistance received by clinical supervisors and clinic staff at the Indigenous dental clinic (4.28±0.8). Conclusions This programme has demonstrated that structured student outplacements are valuable in building relations across cultures especially with Indigenous communities. It has also shown that university engagement with the public health sector can be beneficial to both institutions. Significance for public health An oral health outreach programme is one of the suggested approaches to effectively address the endemic issues of poor oral health among Indigenous people around the world. An Indigenous dental clinical outplacement in Australia provides an example of beneficial outcomes of such an approach. It provides dental students with an opportunity to experience the health issues related to Australian Indigenous communities and prepare future graduates to work comfortably in the public health care system. Indigenous people also develop trust and feel comfortable in receiving oral health care services from non-indigenous clinicians. PMID:27190979

The intrarenal renin-angiotensin system (iRAS) is implicated in the pathogenesis of hypertension, chronic kidney disease and diabetic nephropathy. Urinary angiotensinogen (uAGT) levels reflect the activity of the iRAS and are altered in women with preeclampsia. Since Indigenous Australians suffer high rates and early onset of renal disease, we hypothesised that Indigenous Australian pregnant women, like non-Indigenous women with pregnancy complications, would have altered uAGT levels. The excretion of RAS proteins was measured in non-Indigenous and Indigenous Australian women with uncomplicated or complicated pregnancies (preeclampsia, diabetes/gestational diabetes, proteinuria/albuminuria, hypertension, small/large for gestational age, preterm birth), and in non-pregnant non-Indigenous women. Non-Indigenous pregnant women with uncomplicated pregnancies, had higher uAGT/creatinine levels than non-Indigenous non-pregnant women (P < 0.01), and levels increased as pregnancy progressed (P < 0.001). In non-Indigenous pregnant women with pregnancy complications, uAGT/creatinine was suppressed in the third trimester (P < 0.01). In Indigenous pregnant women with uncomplicated pregnancies, there was no change in uAGT/creatinine with gestational age and uAGT/creatinine was lower in the 2nd and 3rd trimesters than in non-Indigenous pregnant women with uncomplicated pregnancies (P < 0.03, P < 0.007, respectively). The uAGT/creatinine ratios of Indigenous women with uncomplicated or complicated pregnancies were the same. A decrease in uAGT/creatinine with advancing gestational age was associated with increased urinary albumin/creatinine, as is seen in preeclampsia, but it was not specific for this disorder. The reduced uAGT/creatinine in Indigenous pregnant women may reflect subclinical renal dysfunction which limits the ability of the kidney to maintain sodium balance and could indicate an increased risk of pregnancy complications and/or future renal disease.

2015-01-01

The health gap between Indigenous and non-Indigenous Australians may be exacerbated by climate change if temperature extremes have disproportionate adverse effects on Indigenous people. To explore this issue, we analysed the effect of temperature extremes on hospital admissions for respiratory diseases, stratified by age, Indigenous status and sex, for people living in two different climates zones in the Northern Territory during the period 1993–2011. We examined admissions for both acute and chronic respiratory diagnoses, controlling for day of the week and seasonality variables. Our analysis showed that: (1) overall, Indigenous hospital admission rates far exceeded non-Indigenous admission rates for acute and chronic diagnoses, and Top End climate zone admission rates exceeded Central Australia climate zone admission rates; (2) extreme cold and hot temperatures were associated with inconsistent changes in admission rates for acute respiratory disease in Indigenous and non-Indigenous children and older adults; and (3) no response to cold or hot temperature extremes was found for chronic respiratory diagnoses. These findings support our two hypotheses, that extreme hot and cold temperatures have a different effect on hospitalisations for respiratory disease between Indigenous and non-Indigenous people, and that these health risks vary between the different climate zones. We did not, however, find that there were differing responses to temperature extremes in the two populations, suggesting that any increased vulnerability to climate change in the Indigenous population of the Northern Territory arises from an increased underlying risk to respiratory disease and an already greater existing health burden.

Amazingly resilient Indigenous people! Using transformative learning to facilitate positive student engagement with sensitive material.

Jackson, Debra; Power, Tamara; Sherwood, Juanita; Geia, Lynore

2013-12-01

If health professionals are to effectively contribute to improving the health of Indigenous people, understanding of the historical, political, and social disadvantage that has lead to health disparity is essential. This paper describes a teaching and learning experience in which four Australian Indigenous academics in collaboration with a non-Indigenous colleague delivered an intensive workshop for masters level post-graduate students. Drawing upon the paedagogy of Transformative Learning, the objectives of the day included facilitating students to explore their existing understandings of Indigenous people, the impact of ongoing colonisation, the diversity of Australia's Indigenous people, and developing respect for alternative worldviews. Drawing on a range of resources including personal stories, autobiography, film and interactive sessions, students were challenged intellectually and emotionally by the content. Students experienced the workshop as a significant educational event, and described feeling transformed by the content, better informed, more appreciative of other worldviews and Indigenous resilience and better equipped to contribute in a more meaningful way to improving the quality of health care for Indigenous people. Where this workshop differs from other Indigenous classes was in the involvement of an Indigenous teaching team. Rather than a lone academic who can often feel vulnerable teaching a large cohort of non-Indigenous students, an Indigenous teaching team reinforced Indigenous authority and created an emotionally and culturally safe space within which students were allowed to confront and explore difficult truths. Findings support the value of multiple teaching strategies underpinned by the theory of transformational learning, and the potential benefits of facilitating emotional as well as intellectual student engagement when presenting sensitive material.

A Radiation Chemistry Code Based on the Green's Function of the Diffusion Equation

Plante, Ianik; Wu, Honglu

2014-01-01

Stochastic radiation track structure codes are of great interest for space radiation studies and hadron therapy in medicine. These codes are used for a many purposes, notably for microdosimetry and DNA damage studies. In the last two decades, they were also used with the Independent Reaction Times (IRT) method in the simulation of chemical reactions, to calculate the yield of various radiolytic species produced during the radiolysis of water and in chemical dosimeters. Recently, we have developed a Green's function based code to simulate reversible chemical reactions with an intermediate state, which yielded results in excellent agreement with those obtained by using the IRT method. This code was also used to simulate and the interaction of particles with membrane receptors. We are in the process of including this program for use with the Monte-Carlo track structure code Relativistic Ion Tracks (RITRACKS). This recent addition should greatly expand the capabilities of RITRACKS, notably to simulate DNA damage by both the direct and indirect effect.

A holistic model for the selection of environmental assessment indicators to assess the impact of industrialization on indigenous health.

PubMed

Kryzanowski, Julie A; McIntyre, Lynn

2011-01-01

Mainstream environmental assessment (EA) methodologies often inadequately address health, social and cultural impacts of concern for Canadian indigenous communities affected by industrialization. Our objective is to present a holistic, culturally-appropriate framework for the selection of indigenous health indicators for baseline health assessment, impact prediction, or monitoring of impacts over time. We used a critical population health approach to explore the determinants of health and health inequities in indigenous communities and conceptualize the pathways by which industrialization affects these determinants. We integrated and extended key elements from three indigenous health frameworks into a new holistic model for the selection of indigenous EA indicators. The holistic model conceptualizes individual and community determinants of health within external social, economic and political contexts and thus provides a comprehensive framework for selecting indicators of indigenous health. Indigenous health is the product of interactions among multiple determinants of health and contexts. Potential applications are discussed using case study examples involving indigenous communities affected by industrialization. Industrialization can worsen indigenous health inequities by perpetuating the health, social and cultural impacts of historic environmental dispossession. To mitigate impacts, EA should explicitly recognize linkages between environmental dispossession and the determinants of health and health inequities and meaningfully involve indigenous communities in the process.

To investigate trends in hospital admissions involving suicidal behaviour in the Northern Territory (NT) resident population over the period 2001-2013. Estimates of age-standardised rates and average changes in the annual rate of hospital admissions involving suicidal behaviour were calculated by socio-demographic characteristics and types of suicidal behaviour. Overall rates for Indigenous admissions were 2.7 times higher than non-Indigenous admissions and had increased by almost twice as much. While male and female rates of admission were similar for both Indigenous and non-Indigenous residents, the average annual change in rates was greater for Indigenous females (13.4%) compared to males (8.8%) and for non-Indigenous males (7.7%) compared to females (5.2%). Younger and middle-aged Indigenous admissions experienced increasing rates of admissions, whilst trends were similar across age groups for non-Indigenous admissions. Admissions with a diagnosis of suicidal ideation increased the most across all groups. Trends in intentional self-harm admissions differed according to Indigenous status and sex. There have been substantial increases in hospital admissions involving suicidal behaviour in the NT, most markedly for Indigenous residents. Indigenous females and youth appear to be at increasing risk. The steep increase in suicidal ideation across all groups warrants further investigation. © The Royal Australian and New Zealand College of Psychiatrists 2016.

Recent developments in suicide prevention among the Indigenous peoples of Australia.

PubMed

Dudgeon, Pat; Holland, Christopher

2018-04-01

Suicide is an Aboriginal and Torres Strait Islander (hereafter 'Indigenous') population health issue. Over 2015-2016, the Aboriginal and Torres Strait Islander Suicide Prevention Project (ATSISPEP) aimed to identify success factors in Indigenous suicide prevention. For non-Indigenous practitioners working with indigenous clients at risk of suicide, ATSISPEP identified important considerations to make treatment more effective. The start is acknowledging the differences in the historical, cultural, political, social and economic experiences of Indigenous peoples, and their greater exposure to trauma, psychological distress and risks to mental health. These mental health difficulties are specific and more prevalent amongst Indigenous peoples and communities due to the ongoing impacts of colonisation in Australia including a range of social determinants impacting on the well-being of Indigenous peoples today. Working effectively with Indigenous clients also includes being able to establish culturally safe work environments, and the ability of non-Indigenous practitioners to work in a culturally competent and trauma-informed manner. There are also considerations regarding time protocols and client follow-up. Further, postvention responses might be required. Supporting selective suicide prevention activity among younger people (and other groups at increased risk) and community-level work is an important complement to working with Indigenous individuals at risk of suicide.

Reducing the health disparities of Indigenous Australians: time to change focus.

Durey, Angela; Thompson, Sandra C

Indigenous peoples have worse health than non-Indigenous, are over-represented amongst the poor and disadvantaged, have lower life expectancies, and success in improving disparities is limited. To address this, research usually focuses on disadvantaged and marginalised groups, offering only partial understanding of influences underpinning slow progress. Critical analysis is also required of those with the power to perpetuate or improve health inequities. In this paper, using Australia as a case example, we explore the effects of 'White', Anglo-Australian cultural dominance in health service delivery to Indigenous Australians. We address the issue using race as an organising principle, underpinned by relations of power. Interviews with non-Indigenous medical practitioners in Western Australia with extensive experience in Indigenous health encouraged reflection and articulation of their insights into factors promoting or impeding quality health care to Indigenous Australians. Interviews were audio-taped and transcribed. An inductive, exploratory analysis identified key themes that were reviewed and interrogated in light of existing literature on health care to Indigenous people, race and disadvantage. The researchers' past experience, knowledge and understanding of health care and Indigenous health assisted with data interpretation. Informal discussions were also held with colleagues working professionally in Indigenous policy, practice and community settings. Racism emerged as a key issue, leading us to more deeply interrogate the role 'Whiteness' plays in Indigenous health care. While Whiteness can refer to skin colour, it also represents a racialized social structure where Indigenous knowledge, beliefs and values are subjugated to the dominant western biomedical model in policy and practice. Racism towards Indigenous patients in health services was institutional and interpersonal. Internalised racism was manifest when Indigenous patients incorporated racist attitudes and beliefs into their lived experience, lowering expectations and their sense of self-worth. Current health policies and practices favour standardised care where the voice of those who are marginalised is often absent. Examining the effectiveness of such models in reducing health disparities requires health providers to critically reflect on whether policies and practices promote or compromise Indigenous health and wellbeing--an important step in changing the discourse that places Indigenous people at the centre of the problem.

Indigenous populations have poorer health outcomes compared to their non-Indigenous counterparts. The evolution of Indigenous primary health care services arose from mainstream health services being unable to adequately meet the needs of Indigenous communities and Indigenous peoples often being excluded and marginalised from mainstream health services. Part of the solution has been to establish Indigenous specific primary health care services, for and managed by Indigenous peoples. There are a number of reasons why Indigenous primary health care services are more likely than mainstream services to improve the health of Indigenous communities. Their success is partly due to the fact that they often provide comprehensive programs that incorporate treatment and management, prevention and health promotion, as well as addressing the social determinants of health. However, there are gaps in the evidence base including the characteristics that contribute to the success of Indigenous primary health care services in providing comprehensive primary health care. This systematic scoping review aims to identify the characteristics of Indigenous primary health care service delivery models. This systematic scoping review was led by an Aboriginal researcher, using the Joanna Briggs Institute Scoping Review Methodology. All published peer-reviewed and grey literature indexed in PubMed, EBSCO CINAHL, Embase, Informit, Mednar, and Trove databases from September 1978 to May 2015 were reviewed for inclusion. Studies were included if they describe the characteristics of service delivery models implemented within an Indigenous primary health care service. Sixty-two studies met the inclusion criteria. Data were extracted and then thematically analysed to identify the characteristics of Indigenous PHC service delivery models. Culture was the most prominent characteristic underpinning all of the other seven characteristics which were identified - accessible health services, community participation, continuous quality improvement, culturally appropriate and skilled workforce, flexible approach to care, holistic health care, and self-determination and empowerment. While the eight characteristics were clearly distinguishable within the review, the interdependence between each characteristic was also evident. These findings were used to develop a new Indigenous PHC Service Delivery Model, which clearly demonstrates some of the unique characteristics of Indigenous specific models.

Use of indigenous cultural idioms by Chinese immigrant relatives for psychosis: impacts on stigma and psychoeducational approaches.

PubMed

Yang, Lawrence H; Singla, Daisy R

2011-11-01

Indigenous interpretations of mental illness might negatively impact treatment adherence. However, psychiatric "labeling" potentially leads to stigma among Chinese groups, thus encouraging the use of indigenous idioms. We examined how relatives' use of indigenous labeling varied with the consumers' experience of illness and whether indigenous labeling protected relatives from internalized and experienced forms of stigma. Forty-nine relatives of Chinese-immigrant consumers with psychosis were sampled. Although consumers had progressed to the middle stages of psychosis, 39% of relatives used indigenous idioms to label psychosis. Indigenous labeling decreased when illness duration increased and when visual hallucinations were present. Indigenous labeling further predicted lower internalized stigma among relatives. Relatives who used indigenous labeling also reported fewer indirect stigma experiences, although not after controlling for illness severity. The frequency of direct discrimination among relatives did not differ by labeling. These forms of felt stigma might be embedded into relatives' psychoeducation programs to mitigate adverse consequences of psychiatric labeling.

There have been no previous estimates on differences in adult or overall mortality in indigenous peoples in Brazil, although such indicators are extremely important for reducing social iniquities in health in this population segment. Brazil has made significant strides in recent decades to fill the gaps in data on indigenous peoples in the national statistics. The aim of this paper is to present estimated mortality rates for indigenous and non-indigenous persons in different age groups, based on data from the 2010 Population Census. The estimates used the question on deaths from specific household surveys. The results indicate important differences in mortality rates between indigenous and non-indigenous persons in all the selected age groups and in both sexes. These differences are more pronounced in childhood, especially in girls. The indicators corroborate the fact that indigenous peoples in Brazil are in a situation of extreme vulnerability in terms of their health, based on these unprecedented estimates of the size of these differences.

2016-01-01

Present study documents the potential probiotic Lactobacillus isolated from indigenous fermented beverage Raabadi, consumed during summers in Haryana and Rajasthan regions of India. A total of five Raabadi samples were collected aseptically and 54 isolates were purified using MRS medium. All the isolates were assessed for tolerance to low pH and bile salts. It was observed that out of 54 only 24 isolates could survive the simulated gastric conditions. These isolates were further evaluated in vitro for cell surface hydrophobicity, cell surface hydrophobicity, hypocholesteramic activity, anti-oxidative potential, BSH activity, antagonistic activity, and antibiotic resistance profile. In addition, the confirmation of phenol resistance was also done. On the basis of results obtained, the survival rate of isolates was noted and six isolates were finally selected for further studies. Among them Lactobacillus plantarum RYPR1 and RYPC7 showed good survival at pH 2 which shows good acid tolerance. Moreover, L. plantarum RYPR1 showed the highest hydrophobicity (79.13%) and represented the deconjugation of bile salts, which help in their adhesion to epithelial cells and colonization. Furthermore, RYPR1 also exhibited highest cholesterol reduction (59%) and subsequent analysis of results revealed that the above mentioned isolates further exhibit a good hypocholesterolemic effect and could be possibly used to prevent hypercholesterolemia. The present study divulges that L. plantarum RYPR1 has an excellent probiotic potential. PMID:27818658

Transcriptomics Analysis on Excellent Meat Quality Traits of Skeletal Muscles of the Chinese Indigenous Min Pig Compared with the Large White Breed

The Min pig (Sus scrofa) is a well-known indigenous breed in China. One of its main advantages over European breeds is its high meat quality. Additionally, different cuts of pig also show some different traits of meat quality. To explore the underlying mechanism responsible for the differences of meat quality between different breeds or cuts, the longissimus dorsi muscle (LM) and the biceps femoris muscle (BF) from Min and Large White pigs were investigated using transcriptome analysis. The gene expression profiling identified 1371 differentially expressed genes (DEGs) between LM muscles from Min and Large White pigs, and 114 DEGs between LM and BF muscles from the same Min pigs. Gene Ontology (GO) enrichment of biological functions and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that the gene products were mainly involved in the IRS1/Akt/FoxO1 signaling pathway, adenosine 5′-monophosphate-activated protein kinase (AMPK) cascade effects, lipid metabolism and amino acid metabolism pathway. Such pathways contributed to fatty acid metabolism, intramuscular fat deposition, and skeletal muscle growth in Min pig. These results give an insight into the mechanisms underlying the formation of skeletal muscle and provide candidate genes for improving meat quality. It will contribute to improving meat quality of pigs through molecular breeding. PMID:29271915

To examine differences in land use and environmental impacts between colonist and indigenous populations in the northern Ecuadorian Amazon, we combined data from household surveys and remotely sensed imagery that was collected from 778 colonist households in 64 colonization sectors, and 499 households from five indigenous groups in 36 communities. Overall, measures of deforestation and forest fragmentation were significantly greater for colonists than indigenous peoples. On average, colonist households had approximately double the area in agriculture and cash crops and 5.5 times the area in pasture as indigenous households. Nevertheless, substantial variation in land-use patterns existed among the five indigenous groups in measures such as cattle ownership and use of hired agricultural labor. These findings support the potential conservation value of indigenous lands while cautioning against uniform policies that homogenize indigenous ethnic groups. PMID:20337669

Research and the health of indigenous populations in low- and middle-income countries.

Mohindra, K S

2017-06-01

In low- and middle-income countries (LMICs)-when there are available data-a 'health divide' exists between indigenous and non-indigenous populations living in the same society. Despite the limited available evidence suggesting that indigenous populations have high levels of health needs, there is scant research on indigenous health, especially in Africa, China and South Asia. Pursuing research, however, is clouded by the prior negative experiences that indigenous populations have had with researchers. In this paper, we describe the current evidence base on indigenous health in LMICs, propose practical strategies for undertaking future research, and conclude by describing how global health researchers can contribute to improving the health of indigenous populations. © The Author 2015.

2018-01-01

Associations between short sleep duration and obesity and the relationship between obesity and chronic illness are well documented. Obese children are likely to become obese adults. To date, there is a paucity of information regarding sleep duration and quality for Indigenous Australian people. It may be that poor-quality, short sleep is contributing to the gap in health outcomes for Indigenous people compared with non-Indigenous adults and children. This study sought to investigate the possibility that poor sleep quality may be contributing to health outcomes for Indigenous children by exploring associations between sleep duration and body mass index (BMI). Participants included 1253 children aged 7-12 years in Wave 7 of the national Longitudinal Study of Indigenous Children survey. Interviewers asked primary carers about children's sleep times. BMI was derived from measurements of children made by researchers. Regardless of age, relative socio-economic disadvantage and level of remoteness, unhealthy weight was associated with less sleep duration than healthy weight for Indigenous children. The relationship between short sleep duration and BMI in Indigenous children has important implications for their future health outcomes. Both overweight conditions and short sleep are established modifiable risk factors for metabolic dysfunction and other chronic illnesses prominent in the Indigenous population. It is important to consider strategies to optimise both for Indigenous children in an attempt to help 'close the gap' in health outcomes and life expectancy between Indigenous and non-Indigenous people. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Pregnancy and Neonatal Diabetes Outcomes in Remote Australia (PANDORA) study

PubMed Central

2013-01-01

Background Diabetes in pregnancy carries an increased risk of adverse pregnancy outcomes for both the mother and foetus, but it also provides an excellent early opportunity for intervention in the life course for both mother and baby. In the context of the escalating epidemic of chronic diseases among Indigenous Australians, it is vital that this risk is reduced as early as possible in the life course of the individual. The aims of the PANDORA Study are to: (i) accurately assess rates of diabetes in pregnancy in the Northern Territory (NT) of Australia, where 38% of babies are born to Indigenous mothers; (ii) assess demographic, clinical, biochemical, anthropometric, socioeconomic and early life development factors that may contribute to key maternal and neonatal birth outcomes associated with diabetes in pregnancy; and (iii) monitor relevant post-partum clinical outcomes for both the mothers and their babies. Methods/Design Eligible participants are all NT women with diabetes in pregnancy aged 16 years and over. Information collected includes: standard antenatal clinical information, diagnosis and management of diabetes in pregnancy, socio-economic status, standard clinical birth information (delivery, gestational age, birth weight, adverse antenatal and birth outcomes). Cord blood is collected at the time of delivery and detailed neonatal anthropometric measurements performed within 72 hours of birth. Information will also be collected regarding maternal post-partum glucose tolerance and cardio-metabolic risk factor status, breastfeeding and growth of the baby up to 2 years post-partum in the first instance. Discussion This study will accurately document rates and outcomes of diabetes in pregnancy in the NT of Australia, including the high-risk Indigenous Australian population. The results of this study should contribute to policy and clinical guidelines with the goal of reducing the future risk of obesity and diabetes in both mothers and their offspring. PMID:24289168

2013-01-01

Despite growing numbers, indigenous Mexican migrants are relatively invisible to health practitioners who group them with nonindigenous, mestizo Mexican-origin populations. Associations between indigenous and mestizo cultural identifications with psychosocial characteristics and health indicators among indigenous Mexican migrants were examined. Results revealed gender differences in cultural identifications, perceived discrimination, self-esteem, self-efficacy, and various health indicators including depression severity, culture-bound syndromes, and self-rated health. Multivariate regression and structural equation path modeling demonstrated how indigenous cultural identification and perceived discrimination affects health. Findings suggest that interventions should utilize indigenous community-based activities designed to promote self-esteem and the value of indigenous culture, with a focus on females.

Pulsed Inductive Thruster (PIT): Modeling and Validation Using the MACH2 Code

2003-01-01

Numerical modeling of the Pulsed Inductive Thruster exercising the magnetohydrodynamics code, MACH2 aims to provide bilateral validation of the thruster's measured performance and the code's capability of capturing the pertinent physical processes. Computed impulse values for helium and argon propellants demonstrate excellent correlation to the experimental data for a range of energy levels and propellant-mass values. The effects of the vacuum tank wall and massinjection scheme were investigated to show trivial changes in the overall performance. An idealized model for these energy levels and propellants deduces that the energy expended to the internal energy modes and plasma dissipation processes is independent of the propellant type, mass, and energy level.

2017-01-01

Alberta's Indigenous population is growing, yet health care access may be limited. This paper presents a comprehensive review on health care access among Indigenous populations in Alberta with a focus on the health care services use and barriers to health care access. Scientific databases (PubMed, EMBASE, CINAHL, and PsycINFO) and online search engines were systematically searched for studies and grey literature published in English between 2000 and 2013 examining health care services access, use and barriers to access among Indigenous populations in Alberta. Information on health care services use and barriers to use or access was synthesized based on the MOOSE guidelines. Overall, compared to non-Indigenous populations, health care use rates for hospital/emergency room services were higher and health care services use of outpatient specialists was lower among Indigenous peoples. Inadequate numbers of Indigenous health care professionals; a lack of cross-cultural training; fear of foreign environments; and distance from family and friends were barriers to health care use and access. Inequity in social determinants of health among Indigenous peoples and inadequate "health services with prevention approaches," may contribute to present health disparities between Indigenous and non-Indigenous populations in the province.

Study of intra-racial exclusion within Australian Indigenous communities using eco-maps.

2017-04-01

In Australia, 'indigeneity' is not determined by skin colour, but rather by a person's heritage, acceptance by an indigenous community, and active participation in the affairs of that indigenous community. Some people who identify as indigenous, however, have experienced 'colourism' - that is, experiences of social exclusion because of the colour of their skin - from non-Indigenous and also Indigenous Australians. This paper describes research that explored the effect of intra-racial exclusion on the mental health and wellbeing of Indigenous Australians, with a particular focus on skin colour or 'manifest indigeneity'. Framed within a qualitative design, an eco-map was used to guide in-depth interviews with 32 participants that gave rise to personal stories that described the distress of experiencing intra-racial colourism. Findings were derived from a thematic analysis that identified four major themes: 'Growing up black', 'Living on black country', 'Looking black', and 'Fitting in black'. These findings are important because they suggest a way forward for mental health nurses to better understand and support the mental health and wellbeing of Indigenous Australians who have experienced social exclusion as a result of colourism. © 2016 Australian College of Mental Health Nurses Inc.

1) To explore the links between Indigenous Australian children's perspectives on culture, and healthy lifestyle behaviours. 2) To provide insight into how to approach the development of a health intervention targeting lifestyle behaviours in Australian Indigenous children. Seven semi-structured focus groups sessions were conducted with Australian Indigenous children aged 5-12 years living on the South Coast of New South Wales. Audio-recordings were transcribed and thematic analyses were conducted and related to principles of grounded theory. Participants had connections to aspects of Australian Indigenous culture that were embedded in their everyday lives. Healthy lifestyle behaviours (such as healthy eating and physical activity) were found to be interconnected with Australian Indigenous culture and positive emotional wellbeing was identified as an important outcome of connecting Australian Indigenous children to cultural practices. Understanding the importance of culture and its role in healthy lifestyles is critical in the development of health interventions for Indigenous populations. Health interventions embedded with Australian Indigenous culture may have potential to improve physical and emotional health within Australian Indigenous communities. However, it is unlikely that a 'one size fits all' approach to health interventions can be taken. © 2017 The Authors.

Indigenous conceptions of health have been shown to differ from that of their non-Indigenous counterparts. As a result, there remains uncertainty over the appropriateness and value of using existing health-related quality-of-life (HRQoL) instruments in Indigenous communities. The objective of this review was to identify studies that either measure the HRQoL of an Indigenous population or validated a measure used to elicit the HRQoL in an Indigenous population. A systematic review of the published literature was conducted to (1) investigate the extent to which HRQoL instruments are used in Indigenous populations; (2) to identify which instruments have been validated in which populations; and (3) to identify which instruments have been tailored for use with Indigenous populations. Forty-one studies were included in the review. Only three of the 41 studies utilised Indigenous-specific instruments. The remainder (38 studies) utilised generic population or disease-specific instruments. Four studies found specific HRQoL instruments to be valid in these populations and 32 estimated the HRQoL of an Indigenous population. The limited examples of Indigenous-specific instruments highlighted the potential importance to the HRQoL of these populations of domains that lie outside of traditional measures including social and community domains as well as domains relating to culture, diet and land use on top of more traditional HRQoL domains. Ensuring that the HRQoL of Indigenous populations is being appropriately measured is vital to prioritising available resources to the most effective interventions. HRQoL instruments present an opportunity to directly elicit and incorporate Indigenous preferences and conceptions of health into these decisions. Further work is required in the field to ensure that this potential is realised.

Lung cancer and cervical cancer are higher in incidence for Indigenous Australians and survival is worse compared with non-Indigenous Australians. Here we aim to determine if being Indigenous and/or other factors are associated with patients receiving "suboptimal treatment" compared to "optimal treatment" according to clinical guidelines for two cancer types. Data were collected from hospital medical records for Indigenous adults diagnosed with cervical cancer and non-small cell lung cancer (NSCLC) and a frequency-matched comparison group of non-Indigenous patients in the Queensland Cancer Registry between January 1998 and December 2004. The two cancer types were analyzed separately. A total of 105 women with cervical cancer were included in the study, 56 of whom were Indigenous. Indigenous women had higher odds of not receiving optimal treatment according to clinical guidelines (unadjusted OR 7.1; 95% CI, 1.5-33.3), even after adjusting for stage (OR 5.7; 95% CI, 1.2-27.3). Of 225 patients with NSCLC, 198 patients (56% Indigenous) had sufficient information available to be analyzed. The odds of receiving suboptimal treatment were significantly higher for Indigenous compared to non-Indigenous NSCLC patients (unadjusted OR 1.9; 95% CI, 1.0-3.6) and remained significant after adjusting for stage, comorbidity and age (adjusted OR 2.1; 95% CI, 1.1-4.1). The monitoring of treatment patterns and appraisal against guidelines can provide valuable evidence of inequity in cancer treatment. We found that Indigenous people with lung cancer or cervical cancer received suboptimal treatment, reinforcing the need for urgent action to reduce the impact of these two cancer types on Indigenous people. © 2016 John Wiley & Sons Australia, Ltd.

The organizers of the 2014 US National Climate Assessment (NCA) made a concerted effort to reach out to and collaborate with Indigenous peoples, resulting in the most comprehensive information to date on climate change impacts to Indigenous peoples in a US national assessment. Yet, there is still much room for improvement in assessment processes to ensure adequate recognition of Indigenous perspectives and Indigenous knowledge systems. This article discusses the process used in creating the Indigenous Peoples, Land, and Resources NCA chapter by a team comprised of tribal members, agencies, academics, and non-governmental organizations, who worked together to solicit, collect, and synthesize traditional knowledges and data from a diverse array of Indigenous communities across the US. It also discusses the synergy and discord between traditional knowledge systems and science and the emergence of cross-cutting issues and vulnerabilities for Indigenous peoples. The challenges of coalescing information about climate change and its impacts on Indigenous communities are outlined along with recommendations on the types of information to include in future assessment outputs. We recommend that future assessments – not only NCA, but other relevant local, regional, national, and international efforts aimed at the translation of climate information and assessments into meaningful actions – should support integration of Indigenous perspectives in a sustained way that builds respectful relationships and effectively engages Indigenous communities. Given the large number of tribes in the US and the current challenges and unique vulnerabilities of Indigenous communities, a special report focusing solely on climate change and Indigenous peoples is warranted.This article is part of a special issue on “The National Climate Assessment: Innovations in Science and Engagement” edited by Katharine Jacobs, Susanne Moser, and James Buizer.

Over recent years, there has been concerted effort to 'close the gap' in the disproportionately reduced life expectancy and increased morbidity experienced by indigenous compared to non-indigenous persons. Specific to musculoskeletal health, some data suggest that indigenous peoples have a higher risk of sustaining a fracture compared to non-indigenous peoples. This creates an imperative to identify factors that could explain differences in fracture rates. This protocol presents our aim to conduct a systematic review, first, to determine whether differences in fracture rates exist for indigenous versus non-indigenous persons and, second, to identify any risk factors that might explain these differences. We will conduct a systematic search of PubMed, OVID, MEDLINE, CINAHL and EMBASE to identify articles that compare all-cause fracture rates at any skeletal site between indigenous and non-indigenous persons of any age. Eligibility of studies will be determined by 2 independent reviewers. Studies will be assessed for methodological quality using a previously published process. We will conduct a meta-analysis and use established statistical methods to identify and control for heterogeneity where appropriate. Should heterogeneity prevents numerical syntheses, we will undertake a best-evidence analysis to determine the level of evidence for differences in fracture between indigenous and non-indigenous persons. This systematic review will use published data; thus, ethical permissions are not required. In addition to peer-reviewed publication, findings will be presented at (inter)national conferences, disseminated electronically and in print, and will be made available to key country-specific decision-makers with authority for indigenous health.

Enhancing Scalability and Efficiency of the TOUGH2_MP for LinuxClusters

DOE Office of Scientific and Technical Information (OSTI.GOV)

Zhang, Keni; Wu, Yu-Shu

2006-04-17

TOUGH2{_}MP, the parallel version TOUGH2 code, has been enhanced by implementing more efficient communication schemes. This enhancement is achieved through reducing the amount of small-size messages and the volume of large messages. The message exchange speed is further improved by using non-blocking communications for both linear and nonlinear iterations. In addition, we have modified the AZTEC parallel linear-equation solver to nonblocking communication. Through the improvement of code structuring and bug fixing, the new version code is now more stable, while demonstrating similar or even better nonlinear iteration converging speed than the original TOUGH2 code. As a result, the new versionmore » of TOUGH2{_}MP is improved significantly in its efficiency. In this paper, the scalability and efficiency of the parallel code are demonstrated by solving two large-scale problems. The testing results indicate that speedup of the code may depend on both problem size and complexity. In general, the code has excellent scalability in memory requirement as well as computing time.« less

Revisiting Molecular Dynamics on a CPU/GPU system: Water Kernel and SHAKE Parallelization.

We report Graphics Processing Unit (GPU) and Open-MP parallel implementations of water-specific force calculations and of bond constraints for use in Molecular Dynamics simulations. We focus on a typical laboratory computing-environment in which a CPU with a few cores is attached to a GPU. We discuss in detail the design of the code and we illustrate performance comparable to highly optimized codes such as GROMACS. Beside speed our code shows excellent energy conservation. Utilization of water-specific lists allows the efficient calculations of non-bonded interactions that include water molecules and results in a speed-up factor of more than 40 on the GPU compared to code optimized on a single CPU core for systems larger than 20,000 atoms. This is up four-fold from a factor of 10 reported in our initial GPU implementation that did not include a water-specific code. Another optimization is the implementation of constrained dynamics entirely on the GPU. The routine, which enforces constraints of all bonds, runs in parallel on multiple Open-MP cores or entirely on the GPU. It is based on Conjugate Gradient solution of the Lagrange multipliers (CG SHAKE). The GPU implementation is partially in double precision and requires no communication with the CPU during the execution of the SHAKE algorithm. The (parallel) implementation of SHAKE allows an increase of the time step to 2.0fs while maintaining excellent energy conservation. Interestingly, CG SHAKE is faster than the usual bond relaxation algorithm even on a single core if high accuracy is expected. The significant speedup of the optimized components transfers the computational bottleneck of the MD calculation to the reciprocal part of Particle Mesh Ewald (PME).

Indigenous people have disproportionally worse health and lower life expectancy than their non-indigenous counterparts in high-income countries. Cancer data for indigenous people are scarce and incidence has not previously been collectively reported in Australia, New Zealand, Canada, and the USA. We aimed to investigate and compare, for the first time, the cancer burden in indigenous populations in these countries. We derived incidence data from population-based cancer registries in three states of Australia (Queensland, Western Australia, and the Northern Territory), New Zealand, the province of Alberta in Canada, and the Contract Health Service Delivery Areas of the USA. Summary rates for First Nations and Inuit in Alberta, Canada, were provided directly by Alberta Health Services. We compared age-standardised rates by registry, sex, cancer site, and ethnicity for all incident cancer cases, excluding non-melanoma skin cancers, diagnosed between 2002 and 2006. Standardised rate ratios (SRRs) and 95% CIs were computed to compare the indigenous and non-indigenous populations of each jurisdiction, except for the Alaska Native population, which was compared with the white population from the USA. We included 24 815 cases of cancer in indigenous people and 5 685 264 in non-indigenous people from all jurisdictions, not including Alberta, Canada. The overall cancer burden in indigenous populations was substantially lower in the USA except in Alaska, similar or slightly lower in Australia and Canada, and higher in New Zealand compared with their non-indigenous counterparts. Among the most commonly occurring cancers in indigenous men were lung, prostate, and colorectal cancer. In most jurisdictions, breast cancer was the most common cancer in women followed by lung and colorectal cancer. The incidence of lung cancer was higher in indigenous men in all Australian regions, in Alberta, and in US Alaska Natives than in their non-indigenous counterparts. For breast cancer, rates in women were lower in all indigenous populations except in New Zealand (SRR 1·23, CI 95% 1·16-1·32) and Alaska (1·14, 1·01-1·30). Incidence of cervical cancer was higher in indigenous women than in non-indigenous women in most jurisdictions, although the difference was not always statistically significant. There are clear differences in the scale and profile of cancer in indigenous and non-indigenous populations in Australia, New Zealand, Canada, and the USA. Our findings highlight the need for much-improved, targeted programmes of screening, vaccination, and smoking cessation, among other prevention strategies. Governments and researchers need to work in partnership with indigenous communities to improve cancer surveillance in all jurisdictions and facilitate access to cancer data.

Aboriginal and Torres Strait Islander Australians (hereafter respectfully Indigenous Australians) claim that they have been over-researched without corresponding research benefit. This claim raises two questions. The first, which has been covered to some extent in the literature, is about what type(s) of research are likely to achieve benefits for Indigenous people. The second is how researchers report the impact of their research for Indigenous people. This systematic review of Indigenous health reviews addresses the second enquiry. Fourteen electronic databases were systematically searched for Indigenous health reviews which met eligibility criteria. Two reviewers assessed their characteristics and methodological rigour using an a priori protocol. Three research hypotheses were stated and tested: (1) reviews address Indigenous health priority needs; (2) reviews adopt best practice guidelines on research conduct and reporting in respect to methodological transparency and rigour, as well as acceptability and appropriateness of research implementation to Indigenous people; and (3) reviews explicitly report the incremental impacts of the included studies and translation of research. We argue that if review authors explicitly address each of these three hypotheses, then the impact of research for Indigenous peoples' health would be explicated. Seventy-six reviews were included; comprising 55 journal articles and 21 Australian Government commissioned evidence review reports. While reviews are gaining prominence and recognition in Indigenous health research and increasing in number, breadth and complexity, there is little reporting of the impact of health research for Indigenous people. This finding raises questions about the relevance of these reviews for Indigenous people, their impact on policy and practice and how reviews have been commissioned, reported and evaluated. The findings of our study serve two main purposes. First, we have identified knowledge and methodological gaps in documenting Indigenous health research impact that can be addressed by researchers and policy makers. Second, the findings provide the justification for developing a framework allowing researchers and funding bodies to structure future Indigenous health research to improve the reporting and assessment of impact over time.

A strategy to close the gap in relation to Indigenous health is the employment of more Indigenous health professionals. However, despite government reviews, research studies and educational initiatives, Indigenous students' retention and completion rates of tertiary education remains below those of non-Indigenous Australians. To evaluate two enhancements to an Away-from-Base Bachelor of Midwifery program for Indigenous students, namely the appointment of an Indigenous Academic Liaison Midwife to provide academic and cultural support and an additional clinical placement in a high-volume tertiary hospital. In this qualitative study, 10 Indigenous students enrolled in the Away-from-Base Bachelor of Midwifery program participated in one of two focus groups. Focus group transcriptions were subjected to a manual thematic analysis, and key themes were identified and explored. The role of the Indigenous Academic Liaison Midwife was highly valued as students had access to a resource who provided cultural and academic support, and who encouraged and advocated for them. Regular contact with the Indigenous Academic Liaison Midwife enabled students to stay connected with and focussed on their study. Students were overwhelmingly positive about the opportunity to undertake the additional clinical placement, as it exposed them to complex clinical cases they may not have seen in their home communities. The introduction of an Indigenous Academic Liaison Midwife and an additional clinical placement in a high-volume tertiary hospital were perceived as valuable additions to the range of support mechanisms already in place for Indigenous Away-from-Base Bachelor of Midwifery students. These interventions have had a direct impact on retention, course progression and completion rates for Indigenous students. Students expressed enhanced clinical learning and knowledge retention as a result of the additional clinical placement, and the Indigenous Academic Liaison Midwife provided culturally sensitive support for students undertaking remote learning, and during on-campus intensive sessions.

Canada, the United States, Australia, and New Zealand consistently place near the top of the United Nations Development Programme's Human Development Index (HDI) rankings, yet all have minority Indigenous populations with much poorer health and social conditions than non-Indigenous peoples. It is unclear just how the socioeconomic and health status of Indigenous peoples in these countries has changed in recent decades, and it remains generally unknown whether the overall conditions of Indigenous peoples are improving and whether the gaps between Indigenous peoples and other citizens have indeed narrowed. There is unsettling evidence that they may not have. It was the purpose of this study to determine how these gaps have narrowed or widened during the decade 1990 to 2000. Census data and life expectancy estimates from government sources were used to adapt the Human Development Index (HDI) to examine how the broad social, economic, and health status of Indigenous populations in these countries have changed since 1990. Three indices - life expectancy, educational attainment, and income - were combined into a single HDI measure. Between 1990 and 2000, the HDI scores of Indigenous peoples in North America and New Zealand improved at a faster rate than the general populations, closing the gap in human development. In Australia, the HDI scores of Indigenous peoples decreased while the general populations improved, widening the gap in human development. While these countries are considered to have high human development according to the UNDP, the Indigenous populations that reside within them have only medium levels of human development. The inconsistent progress in the health and well-being of Indigenous populations over time, and relative to non-Indigenous populations, points to the need for further efforts to improve the social, economic, and physical health of Indigenous peoples.

Sharing What We Know about Living a Good Life: Indigenous Approaches to Knowledge Translation

2015-01-01

Knowledge Translation (KT), a core priority in Canadian health research, policy, and practice for the past decade, has a long and rich tradition within Indigenous communities. In Indigenous knowledge systems the processes of “knowing” and “doing” are often intertwined and indistinguishable. However, dominant KT models in health science do not typically recognize Indigenous knowledge conceptualizations, sharing systems, or protocols and will likely fall short in Indigenous contexts. There is a need to move towards KT theory and practice that embraces diverse understandings of knowledge and that recognizes, respects, and builds on pre-existing knowledge systems. This will not only result in better processes and outcomes for Indigenous communities, it will also provide rich learning for mainstream KT scholarship and practice. As professionals deeply engaged in KT work, health librarians are uniquely positioned to support the development and implementation of Indigenous KT. This article provides information that will enhance the ability of readers from diverse backgrounds to promote and support Indigenous KT efforts, including an introduction to Indigenous knowledge conceptualizations and knowledge systems; key contextual issues to consider in planning, implementing, or evaluating KT in Indigenous settings; and contemporary examples of Indigenous KT in action. The authors pose critical reflection questions throughout the article that encourage readers to connect the content with their own practices and underlying knowledge assumptions. PMID:26793244

With the recognized need for health systems' improvements in the circumpolar and indigenous context, there has been a call to expand the research agenda across all sectors influencing wellness and to recognize academic and indigenous knowledge through the research process. Despite being recognized as a distinct body of knowledge in international forums and across indigenous groups, examples of methods and theories based on indigenous knowledge are not well documented in academic texts or peer-reviewed literature on health systems. This paper describes the use of a consensus-based, mixed method with indigenous knowledge by an experienced group of researchers and indigenous knowledge holders who collaborated on a study that explored indigenous values underlying health systems stewardship. The method is built on the principles of Etuaptmumk or two-eyed seeing, which aim to respond to and resolve the inherent conflicts between indigenous ways of knowing and the scientific inquiry that informs the evidence base in health care. Mixed methods' frameworks appear to provide a framing suitable for research questions that require data from indigenous knowledge sources and western knowledge. The nominal consensus method, as a western paradigm, was found to be responsive to embedding of indigenous knowledge and allowed space to express multiple perspectives and reach consensus on the question at hand. Further utilization and critical evaluation of this mixed methodology with indigenous knowledge are required.

Qatar Genome Project was launched in 2013 with the intent to sequence the genome of each Qatari citizen in an effort to protect Qataris from the high rate of indigenous genetic diseases by allowing the mapping of disease-causing variants/rare variants and establishing a Qatari reference genome. Indeed, this project is expected to have numerous global benefits because the elevated homogeneity of the Qatari population, that will make Qatar an excellent genetic laboratory that will generate a wealth of data that will allow us to make sense of the genotype-phenotype correlations of many diseases, especially the complex multifactorial diseases, and will pave the way for changing the traditional medical practice of looking first at the phenotype rather than the genotype. © 2016 John Wiley & Sons Ltd.

Reconstructing Indigenous ethnicities: the Arapium and Jaraqui peoples of the lower Amazon, Brazil.

PubMed

Bolaños, Omaira

2010-01-01

In Latin America, indigenous identity claims among people not previously recognized as such by the state have become a key topic of anthropological and sociological research. Scholars have analyzed the motivations and political implications of this trend and the impacts of indigenous population's growth on national demographic indicators. However, little is known about how people claiming indigenous status constructs the meaning of their indigenous ethnicity. Drawing from sixty-four indepth interviews, focus-group analyses, and participant observation, this article explores the double process of identity construction: the reconstruction of the Arapium indigenous identity and the creation of the Jaraqui indigenous identity in Brazil's Lower Amazon. The findings reveal six themes that contribute to the embodiment of a definition of indigenous identity and the establishment of a discursive basis to claim recognition: sense of rootedness, historical memory, historical transformation, consciousness, social exclusion, and identity politics.

Indigenous healing is commonly practiced in Middle East. Little is known about trends of indigenous therapies among patients with psychiatric disorders in Iraq. To determine and compare rates and predictors of indigenous healings by individuals with psychiatric disorders, and the practiced rituals among Arabic and Kurdish ethnicities in Iraq, patients aged 18 year and older attending outpatients in Erbil and Najaf were assessed for their prior contacts with indigenous healers. About 48.9 % had indigenous healer's consultations before visiting their psychiatrists; the figure was three times higher among Arabs than Kurds. Higher consultation rate was detected among younger and less formally educated patients. Fourteen types of religious therapeutic rituals have been practiced. Indigenous healing is widespread in Iraq. It is more common among Arabs, younger and less educated people with psychiatric disorders. Participants consider indigenous healing for their psychiatric more than non-psychiatric disorders.

The problem of life expectancy of indigenous and non-indigenous population of northern territories of the Russian Federation is considered in terms of economic growth and industrial development of the northern territories. The importance of prolonging the period of active working age of non-indigenous population of Khanty-Mansi Autonomous Okrug-Ugra and Yamalo-Nenets Autonomous Okrug is increasing. Four directions for possible prolongation of the active life of non-indigenous population were presented. The problem of comparative dynamics of age-related changes of cardiovascular system on three specific age groups of female indigenous and non-indigenous population is being considered. A decrease in volume of quasi-attractors in the phase space of states is equivalent to strengthening of physical activity, which is typical of normal aging. It is proposed to use the mathematical pattern to reduce these volumes in assessing the dynamics of human aging in the North.

Nurturing spiritual well-being among older people in Australia: Drawing on Indigenous and non-Indigenous way of knowing.

2017-09-01

The meaning of spiritual well-being as a health dimension is often contested and neglected in policy and practice. This paper explores spiritual well-being from both an Indigenous and a non-Indigenous perspective. We drew on Indigenous and non-Indigenous methodologies to explore the existing knowledge around spiritual well-being and its relationship with health. The Indigenous perspective proposed that spiritual well-being is founded in The Dreaming, informs everyday relationships and can impact on health. The non-Indigenous perspective suggested that spiritual well-being is shaped by culture and religion, is of increased importance as one ages, and can improve coping and resilience stressors. Situating these perspectives side by side allows us to learn from both, and understand the importance of spirituality in people's lives. Further research is required to better address the spiritual well-being/health connection in policy and practice. © 2016 AJA Inc.

Indigenous Australians are known to be at greater risk of morbidity and mortality from mental health related conditions, but most available data relate to the use of mental health services, and little is known about other aspects of social and emotional wellbeing. Using the first available nationally representative data, we examined the prevalence and patterning of psychological distress among Indigenous Australian adults and compared these with corresponding data from the non-Indigenous population. The analysis used weighted data on psychological distress, as measured by a modified Kessler Psychological Distress score (K5), and a range of socio-demographic measures for 5,417 Indigenous and 15,432 non-Indigenous adults aged 18-64 years from two nationally representative surveys. Very high psychological distress (VHPD) was defined as a K5 score ≥ 15 (possible range = 5-25). Indigenous adults were about three times more likely than non-Indigenous adults to be classified with VHPD: 14.5% (95% confidence interval (CI) 12.9-16.0%) versus 5.5% (95% CI 5.0-5.9%). After adjusting for age, most socio-demographic variables were significantly associated with VHPD in both populations, although the relative odds were generally larger among non-Indigenous people. Indigenous people in remote areas had a lower prevalence of VHPD than their non-remote counterparts, and only marital status, main language, and food insecurity were significantly associated with VHPD in remote areas. Higher absolute levels of VHPD combined with smaller socio-demographic gradients in the Indigenous population suggest the importance of risk factors such as interpersonal racism, marginalization and dispossession, chronic stress and exposure to violence that are experienced by Indigenous Australians with common and/or cross-cutting effects across the socioeconomic spectrum. The lower prevalence of VHPD and lack of association with many socio-demographic variables in remote areas suggests either that the instrument may be less valid for Indigenous people living in remote areas or that living in an Indigenous majority environment (such as exists in most remote communities) may mitigate the risk of psychological distress to some degree.

Indigenous women in Mesoamerica experience disproportionately high maternal mortality rates and are less likely to have institutional deliveries. Identifying correlates of institutional delivery, and satisfaction with institutional deliveries, may help improve facility utilization and health outcomes in this population. We used baseline surveys from the Salud Mesoamérica Initiative to analyze data from 10,895 indigenous and non-indigenous women in Guatemala and Mexico (Chiapas State) and indigenous women in Panama. We created multivariable Poisson regression models for indigenous (Guatemala, Mexico, Panama) and non-indigenous (Guatemala, Mexico) women to identify correlates of institutional delivery and satisfaction. Compared to their non-indigenous peers, indigenous women were substantially less likely to have an institutional delivery (15.2% vs. 41.5% in Guatemala (P<0.001), 29.1% vs. 73.9% in Mexico (P<0.001), and 70.3% among indigenous Panamanian women). Indigenous women who had at least one antenatal care visit were more than 90% more likely to have an institutional delivery (adjusted risk ratio (aRR) = 1.94, 95% confidence interval (CI): 1.44-2.61), compared to those who had no visits. Indigenous women who were advised to give birth in a health facility (aRR = 1.46, 95% CI: 1.18-1.81), primiparous (aRR = 1.44, 95% CI: 1.24-1.68), informed that she should have a Caesarean section (aRR = 1.41, 95% CI: 1.21-1.63), and had a secondary or higher level of education (aRR = 1.36, 95% CI: 1.04-1.79) also had substantially higher likelihoods of institutional delivery. Satisfaction among indigenous women was associated with being able to be accompanied by a community health worker (aRR = 1.15, 95% CI: 1.05-1.26) and facility staff speaking an indigenous language (aRR = 1.10, 95% CI: 1.02-1.19). Additional effort should be exerted to increase utilization of birthing facilities by indigenous and poor women in the region. Improving access to antenatal care and opportunities for higher-level education may increase institutional delivery rates, and providing culturally adapted services may improve satisfaction.

A unique collection of computer codes, Space Debris Surfaces (SD_SURF), have been developed to assist in the design and analysis of space debris protection systems. SD_SURF calculates and summarizes a vehicle's vulnerability to space debris as a function of impact velocity and obliquity. An SD_SURF analysis will show which velocities and obliquities are the most probable to cause a penetration. This determination can help the analyst select a shield design that is best suited to the predominant penetration mechanism. The analysis also suggests the most suitable parameters for development or verification testing. The SD_SURF programs offer the option of either FORTRAN programs or Microsoft-EXCEL spreadsheets and macros. The FORTRAN programs work with BUMPERII. The EXCEL spreadsheets and macros can be used independently or with selected output from the SD_SURF FORTRAN programs. Examples will be presented of the interaction between space vehicle geometry, the space debris environment, and the penetration and critical damage ballistic limit surfaces of the shield under consideration.

BEARKIMPE-2: A VBA Excel program for characterizing granular iron in treatability studies

The selection of a suitable kinetic model to investigate the reaction rate of a contaminant with granular iron (GI) is essential to optimize the permeable reactive barrier (PRB) performance in terms of its reactivity. The newly developed Kinetic Iron Model (KIM) determines the surface rate constant (k) and sorption parameters (Cmax &J) which were not possible to uniquely identify previously. The code was written in Visual Basic (VBA), within Microsoft Excel, was adapted from earlier command line FORTRAN codes, BEARPE and KIMPE. The program is organized with several user interface screens (UserForms) that guide the user step by step through the analysis. BEARKIMPE-2 uses a non-linear optimization algorithm to calculate transport and chemical kinetic parameters. Both reactive and non-reactive sites are considered. A demonstration of the functionality of BEARKIMPE-2, with three nitroaromatic compounds showed that the differences in reaction rates for these compounds could be attributed to differences in their sorption behavior rather than their propensities to accept electrons in the reduction process.

Indigenous populations of Australia, Canada, New Zealand, and the United States of America (USA) experience a higher prevalence of arthritis conditions. Differences in clinical outcomes and mortality may reflect healthcare service use inequities. The objective of this study was to summarize healthcare service use patterns described in the existing literature in order to identify gaps and inform strategies to limit the pronounced negative impact of arthritis on Indigenous populations. Medline, EMBASE, CINAHL, and Indigenous-specific electronic databases (to June 2015) were used to identify cohort, case-control and cross-sectional studies describing healthcare service use by Indigenous populations with specified inflammatory arthritis, osteoarthritis, or rheumatic disease conditions. We extracted information on the study setting and methodology, primary outcome and assessed study quality, and risk of bias. In total, 19 studies were identified describing three types of healthcare service use: physician visits, hospitalizations, and surgeries. In Canada and New Zealand, Indigenous populations had 36-51% fewer visits to specialists than the non-Indigenous population. Indigenous populations in Canada, New Zealand, and the USA had 37-300% more hospitalizations due to arthritis complications than the non-Indigenous population. Indigenous populations in Australia, Canada, and New Zealand had 27-85% fewer arthroplasties for osteoarthritis than the non-Indigenous population. Indigenous populations had higher hospitalization rates but lower use of specialized services for arthritis conditions. Strategies to improve access to specialized arthritis services might reduce health outcome inequities. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

Xpey' Relational Environments: an analytic framework for conceptualizing Indigenous health equity.

Both health equity research and Indigenous health research are driven by the goal of promoting equitable health outcomes among marginalized and underserved populations. However, the two fields often operate independently, without collaboration. As a result, Indigenous populations are underrepresented in health equity research relative to the disproportionate burden of health inequities they experience. In this methodological article, we present Xpey' Relational Environments, an analytic framework that maps some of the barriers and facilitators to health equity for Indigenous peoples. Health equity research needs to include a focus on Indigenous populations and Indigenized methodologies, a shift that could fill gaps in knowledge with the potential to contribute to 'closing the gap' in Indigenous health. With this in mind, the Equity Lens in Public Health (ELPH) research program adopted the Xpey' Relational Environments framework to add a focus on Indigenous populations to our research on the prioritization and implementation of health equity. The analytic framework introduced an Indigenized health equity lens to our methodology, which facilitated the identification of social, structural and systemic determinants of Indigenous health. To test the framework, we conducted a pilot case study of one of British Columbia's regional health authorities, which included a review of core policies and plans as well as interviews and focus groups with frontline staff, managers and senior executives. ELPH's application of Xpey' Relational Environments serves as an example of the analytic framework's utility for exploring and conceptualizing Indigenous health equity in BC's public health system. Future applications of the framework should be embedded in Indigenous research methodologies.

Multidimensional multiphysics analysis of TRISO-coated particle fuel using the BISON finite-element based nuclear fuels code is described. The governing equations and material models applicable to particle fuel and implemented in BISON are outlined. Code verification based on a recent IAEA benchmarking exercise is described, and excellant comparisons are reported. Multiple TRISO-coated particles of increasing geometric complexity are considered. It is shown that the code's ability to perform large-scale parallel computations permits application to complex 3D phenomena while very efficient solutions for either 1D spherically symmetric or 2D axisymmetric geometries are straightforward. Additionally, the flexibility to easily include new physical andmore » material models and uncomplicated ability to couple to lower length scale simulations makes BISON a powerful tool for simulation of coated-particle fuel.

2016-11-01

Indigenous peoples within the Murray-Darling Basin have traditionally struggled for the recognition of their cultural, social, environmental, spiritual, commercial and economic connection to the waters that they have traditionally used, as well as their right to engage in all stages of water planning processes. Despite Australian national and federal frameworks providing for the inclusion of Indigenous Australians' objectives in planning frameworks, water plans have rarely addressed these objectives in water, or the strategies to achieve them. Indeed, insufficient resources, a lack of institutional capacity in both Indigenous communities and agencies and an inadequate understanding of Indigenous people's objectives in water management have limited the extent to which Indigenous objectives are addressed in water plans within the Murray-Darling Basin. In this context, the adoption of specific guidelines to meet Indigenous requirements in relation to basin water resources is crucial to support Indigenous engagement in water planning processes. Using insights from participatory planning methods and human rights frameworks, this article outlines a set of alternative and collaborative guidelines to improve Indigenous involvement in water planning and to promote sustainable and just water allocations.

There is a growing body of research linking urban transport systems to inequities in health. However, there is a lack of research providing evidence of the effect of transport systems on indigenous family wellbeing. We examined the connections between urban transport and the health and wellbeing of Māori, the indigenous people of New Zealand. We provide an indigenous exploration of current urban transport systems, with a particular focus on the impacts of car dependence and the need for culturally relevant travel. We interviewed nineteen Māori participants utilising qualitative research techniques underpinned by an indigenous research methodology (Kaupapa Māori). The data highlighted the importance of accessing cultural activities and sites relevant to 'being Māori', and issues with affordability and safety of public transport. Understanding the relationship between indigenous wellbeing and transport systems that goes further than limited discourses of inequity is essential to improving transport for indigenous wellbeing. Providing an indigenous voice in transport decision-making will make it more likely that indigenous health and wellbeing is prioritised in transport planning. Copyright © 2013.

Coronial Practice, Indigeneity and Suicide.

2018-04-16

All available data suggest that, like many other Indigenous peoples, Australian Aborigines are significantly more likely to kill themselves than are non-Aboriginal Australians. This statistical disparity is normally positioned an objective, ontological and undeniable social fact, a fact best explained as a function of endemic community disadvantage and disenfranchisement. This research explores the possibility that higher-than-normal Aboriginal suicide rates may also be a function of coronial decision-making practices. Based upon in-depth interviews with 32 coroners from across Australia, the following conclusions emerged from the data. First, coroners have differing perceptions of Indigenous capacity, and are less likely to have concerns about intent when the suicide is committed by an Indigenous person. Second, coroners have identified divergent scripts of Indigenous suicide, particularly its spontaneity and public location, and this supports rather than challenges, a finding of suicide. Third, the coronial perception of Indigenous life is a factor which influences a suicide determination for Indigenous deaths. Finally, the low level of Indigenous engagement with the coronial system, and the unlikelihood of a challenge to the finding of suicide by Indigenous families, means that a coronial determination of suicide is more likely.

Indigenous communities in Namibia possess a rich indigenous knowledge expressed within many practices of these communities. Indigenous wild edible fruits are available along the Namibian 13 regions of which it forms a rich source of vitamins, fibres, minerals and a heterogeneous collection of bioactive compounds referred to as phytochemicals for indigenous people's diet. The aim of this study was to record the different IKS practices on the indigenous fruit trees in Ohangwena and Oshikoto regions of Namibia. An ethnobotanical survey was undertaken to collect information from local communities from 23-29 October 2011. Data was collected through the use of questionnaires and personal interviews during field trips in the Ohangwena and Oshikoto regions. A total of 65 respondents were interviewed; 54%; women, 38%; men and 8%; both in group interviews. The majority of the people interviewed were in their thirty's, with the youngest being 18 years old and the oldest being 98 years old. Forty three plant specimens were collected from the two regions; these specimens belong to 20 genera and 25 species. Regarding to the indigenous knowledge; 87%; of the respondents indicated that their knowledge on indigenous fruits was learnt mainly through their parent. Indigenous people's perception on declining indigenous fruits revealed that 56.3%; of the respondents reported that indigenous fruits were declining. Only a 42.2%; indicated that the indigenous fruits populations are increasing. Regarding to the management practices to improve the production of these indigenous fruit trees; 38.6%; reported that there are some efforts on management practices; on the other hand 61.4%; reported there are no management practices on the indigenous fruit trees in their areas. Four species were found to be the most frequently used and mentioned fruits which need to be given high preference in terms of conservation are: Berchemia discolor, Hyphaene petersiana, Sclerocarya birrea and Diospyros mespiliformis. The following diseases and ailments have been reported to be treated by the indigenous fruit trees which include: toothache, diarrhoea, cough, tonsillitis, burns, skin allergy, stomach ache, snake bit, constipation, etc. 28%; of the respondents mentioned an ethno-veterinary use(s) of these fruits, e.g. the use of the Ziziphus mucronata roots to treat diarrhoea in cattle, the bark of eembe (Berchemia discolor) to treat calf weakness. The local communities in Oshikoto and Ohangwena regions have relatively good knowledge and practices regarding the indigenous fruit. This study enhances our understanding on the indigenous fruit in Namibia and their uses by local communities.

Meigu goat (Capra hircus) is one of the indigenous goat breeds in China. Our research findings revealed that the entire mitochondrial genome of Meigu goat was 16,643 bp in length. The contents of A, C, T and G in the mitochondrial genome were 33.59%, 26.05%, 27.31% and 13.05%, respectively. The mitogenome of meigu goat contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region. Components of the Meigu goat's mitogenome were similar to those of other Capra hircus in gene arrangement and composition. These results could provide essential information for molecular phylogenetic and evolutionary analyses of domestic goats.

Harwood, Matire

2010-01-01

Indigenous peoples often have the worst health status in comparison to non-indigenous people in their own nations; urgent action to address the health inequities for indigenous people is required. The role of rehabilitation in addressing health and disability inequities is particularly important due to the health need of indigenous peoples; the unequal distribution of health determinants; and disparities in access to, quality of care through and outcomes following rehabilitation. This article will present a perspective for Māori, the indigenous peoples of New Zealand, on a framework for improving rehabilitation services for Māori and ultimately their health and wellbeing.

Aside from the admixture between indigenous people and people from overseas, populations in Mexico changed drastically after the Spanish conquest of the sixteenth century, forming an intricate history that has been underutilized in understanding the genetic population structure of Mexicans. To infer historical processes of isolation, dispersal, and assimilation, we examined the phylogeography of mitochondrial (mt) DNA and Y-chromosome lineages in 3,026 individuals from 10 urban and nine indigenous populations by identifying single nucleotide polymorphisms. A geographic array with a predominance of Amerindian lineages was observed for mtDNA, with northern indigenous populations being divergent from the central and southern indigenous populations; urban populations showed low differentiation with isolation by distance. Y-chromosome variation distinguished urban and indigenous populations through the Amerindian haplogroup Q frequency. The MtDNA and the Y-chromosome together primarily distinguished urban and indigenous populations, with different geographic arrays for both. Gene flow across geographical distance and between the urban and indigenous realms appears to have altered the pre-Hispanic phylogeography in central and southern Mexico, mainly by displacement of women, while maintaining the indigenous isolation in the north, southeast, and Zapotec regions. Most Amerindian mtDNA diversity currently occurs in urban populations and appears to be reduced among indigenous people.

A needs analysis was undertaken to determine the quality and effectiveness of mental health services to Indigenous consumers within a health district of Southern Queensland. The study focussed on identifying gaps in the service provision for Indigenous consumers. Tools and methodologies were developed to achieve this. Data were collected through the distribution of questionnaires to the target populations: district health service staff and Indigenous consumers. Questionnaires were developed through consultation with the community and the Steering Committee in order to achieve culturally appropriate wording. Of prime importance was the adaptation of questionnaire language so it would be fully understood by Indigenous consumers. Both questionnaires were designed to provide a balanced perspective of current mental health service needs for Indigenous people within the mental health service. Results suggest that existing mental health services do not adequately meet the needs of Indigenous people. Recommendations arising from this study indicate a need for better communication and genuine partnerships between the mental health service and Indigenous people that reflect respect of cultural heritage and recognises the importance of including Indigenous people in the design and management of mental health services. Attention to the recommendations from this study will help ensure a culturally appropriate and effective mental health service for Indigenous consumers.

To examine the risk factors, incidence, consequences and existing prevention strategies for falls and fall-related injury in older indigenous people. Relevant literature was identified through searching 14 electronic databases, a range of institutional websites, online search engines and government databases, using search terms pertaining to indigenous status, injury and ageing. Thirteen studies from Australia, the United States, Central America and Canada were identified. Few studies reported on fall rates but two reported that around 30% of indigenous people aged 45 years and above experienced at least one fall during the past year. The most common hospitalised fall injuries among older indigenous people were hip fracture and head injury. Risk factors significantly associated with falls within indigenous populations included poor mobility, a history of stroke, epilepsy, head injury, poor hearing and urinary incontinence. No formally evaluated, indigenous-specific fall prevention interventions were identified. Falls are a significant and growing health issue for older indigenous people worldwide that can lead to severe health consequences and even death. No fully-evaluated, indigenous-specific fall prevention programs were identified. Implications for Public Health: Research into fall patterns and fall-related injury among indigenous people is necessary for the development of appropriate fall prevention interventions. © 2016 Public Health Association of Australia.

Meeting Indigenous peoples' objectives in environmental flow assessments: Case studies from an Australian multi-jurisdictional water sharing initiative

The multi-dimensional relationships that Indigenous peoples have with water are only recently gaining recognition in water policy and management activities. Although Australian water policy stipulates that the native title interests of Indigenous peoples and their social, cultural and spiritual objectives be included in water plans, improved rates of Indigenous access to water have been slow to eventuate, particularly in those regions where the water resource is fully developed or allocated. Experimentation in techniques and approaches to both identify and determine Indigenous water requirements will be needed if environmental assessment processes and water sharing plans are to explicitly account for Indigenous water values. Drawing on two multidisciplinary case studies conducted in Australia's Murray-Darling Basin, we engage Indigenous communities to (i) understand their values and explore the application of methods to derive water requirements to meet those values; (ii) assess the impact of alternative water planning scenarios designed to address over-allocation to irrigation; and (iii) define additional volumes of water and potential works needed to meet identified Indigenous requirements. We provide a framework where Indigenous values can be identified and certain water needs quantified and advance a methodology to integrate Indigenous social, cultural and environmental objectives into environmental flow assessments.

Yarning/Aboriginal storytelling: towards an understanding of an Indigenous perspective and its implications for research practice.

2013-12-01

There is increasing recognition of Indigenous perspectives from various parts of the world in relation to storytelling, research and its effects on practice. The recent emergence of storytelling or yarning as a research method in Australian Aboriginal and Torres Strait Island studies and other Indigenous peoples of the world is gaining momentum. Narratives, stories, storytelling and yarning are emerging methods in research and has wide ranging potential to shape conventional research discourse making research more meaningful and accessible for researchers. In this paper we argue for the importance of Indigenous research methods and Indigenous method(ology), within collaborative respectful partnerships with non-Indigenous researchers. It is imperative to take these challenging steps together towards better outcomes for Indigenous people and their communities. In the Australian context we as researchers cannot afford to allow the gap between Aboriginal and Torres Strait Islanders and mainstream Australia health outcomes to grow even wider. One such pathway is the inclusion of Aboriginal storytelling or yarning from an Aboriginal and Torres Strait perspective within Indigenous and non-Indigenous research paradigms. Utilising Aboriginal storytelling or yarning will provide deeper understanding; complementing a two-way research paradigm for collaborative research. Furthermore, it has significant social implications for research and clinical practice amongst Indigenous populations; thus complementing the biomedical medical paradigm.

Mood and anxiety disorders in Australia and New Zealand's indigenous populations: A systematic review and meta-analysis.

The Indigenous populations of Australia and New Zealand are considered at higher risk of mood and anxiety disorders but many studies do not include direct comparisons with similar non-Indigenous controls. We conducted a systematic search of relevant electronic databases, as well as snowballing and targeted searches of the grey literature. Studies were included for meta-analysis if they compared rates of mood and anxiety disorders between Indigenous and non-Indigenous Australians or Maori. Seven Australian and 10 NZ studies were included. Overall, Indigenous people in both countries did not have significantly higher rates of disorder. However, in terms of specific disorders, there were differences in risk by gender, country (Australia or NZ), disorder type, and prevalence (current, 12-month or lifetime). For instance, Indigenous Australians and Maori both had significantly lower rates of simple phobias (current prevalence) and Maori participants had significantly lower rates of both lifetime simple phobia and generalised anxiety disorders. By contrast, Indigenous Australians had significantly higher rates of bipolar affective disorder and social phobia (current prevalence). Generalisations regarding the risk of psychiatric disorders in Indigenous people cannot therefore be made as this varies by several factors. These include disorder type, sociodemographic factors, Indigenous origin and study method. Copyright © 2017. Published by Elsevier B.V.

The world's Indigenous peoples are experiencing an unprecedented epidemic of type 2 diabetes [T2DM] but little has been published describing the complications burden. The objective of this paper was to conduct a systematic review of T2DM complications in Indigenous populations worldwide. A literature review was conducted using PubMed and EMBASE to examine available complications data. Country, Indigenous population, authors, publication year, total sample size, Indigenous sample size, age, methodology, and prevalence of nephropathy, end-stage renal disease, retinopathy, neuropathy, lower extremity amputations, cardiovascular disease, hospitalizations and mortality due to diabetes were recorded. One-hundred and eleven studies were selected. Results revealed a disproportionate burden of disease complications among all Indigenous peoples regardless of their geographic location. Complication rates were seen to vary widely across Indigenous groups. Gaps were found in the published literature on complications among Indigenous populations, especially those living in underdeveloped countries. These gaps may be in part due to the challenges caused by varying operational practices, research methodologies, and definitions of the term Indigenous, making documentation of rates among these peoples problematic. Comprehensive surveillance applying standardized definitions and methodologies is needed to design targeted prevention and disease management strategies for Indigenous peoples with T2DM.

Selection and Use of Health Services for Infants' Needs by Indigenous Mothers in Canada: Integrative Literature Review.

2018-06-01

In Canada, Indigenous infants experience significant health disparities when compared to non-Indigenous infants, including significantly higher rates of birth complications and infant mortality rates. The use of primary health care is one way to improve health outcomes; however, Indigenous children may use health services less often than non-Indigenous children. To improve health outcomes within this growing population, it is essential to understand how caregivers, defined here as mothers, select and use health services in Canada. This integrative review is the first to critique and synthesize what is known of how Indigenous mothers in Canada experience selecting and using health services to meet the health needs of their infants. Themes identified suggest both Indigenous women and infants face significant challenges; colonialism has had, and continues to have, a detrimental impact on Indigenous mothering; and very little is known about how Indigenous mothers select and use health services to meet the health of their infants. This review revealed significant gaps in the literature and a need for future research. Suggestions are made for how health providers can better support Indigenous mothers and infants in their use of health services, based on what has been explored in the literature to date.

Energy-Constrained Recharge, Assimilation, and Fractional Crystallization (EC-RAχFC): A Visual Basic computer code for calculating trace element and isotope variations of open-system magmatic systems

2007-11-01

Volcanic and plutonic rocks provide abundant evidence for complex processes that occur in magma storage and transport systems. The fingerprint of these processes, which include fractional crystallization, assimilation, and magma recharge, is captured in petrologic and geochemical characteristics of suites of cogenetic rocks. Quantitatively evaluating the relative contributions of each process requires integration of mass, species, and energy constraints, applied in a self-consistent way. The energy-constrained model Energy-Constrained Recharge, Assimilation, and Fractional Crystallization (EC-RaχFC) tracks the trace element and isotopic evolution of a magmatic system (melt + solids) undergoing simultaneous fractional crystallization, recharge, and assimilation. Mass, thermal, and compositional (trace element and isotope) output is provided for melt in the magma body, cumulates, enclaves, and anatectic (i.e., country rock) melt. Theory of the EC computational method has been presented by Spera and Bohrson (2001, 2002, 2004), and applications to natural systems have been elucidated by Bohrson and Spera (2001, 2003) and Fowler et al. (2004). The purpose of this contribution is to make the final version of the EC-RAχFC computer code available and to provide instructions for code implementation, description of input and output parameters, and estimates of typical values for some input parameters. A brief discussion highlights measures by which the user may evaluate the quality of the output and also provides some guidelines for implementing nonlinear productivity functions. The EC-RAχFC computer code is written in Visual Basic, the programming language of Excel. The code therefore launches in Excel and is compatible with both PC and MAC platforms. The code is available on the authors' Web sites http://magma.geol.ucsb.edu/and http://www.geology.cwu.edu/ecrafc) as well as in the auxiliary material.

Ornaments Reveal Resistance of North European Cultures to the Spread of Farming

2015-01-01

The transition to farming is the process by which human groups switched from hunting and gathering wild resources to food production. Understanding how and to what extent the spreading of farming communities from the Near East had an impact on indigenous foraging populations in Europe has been the subject of lively debates for decades. Ethnographic and archaeological studies have shown that population replacement and admixture, trade, and long distance diffusion of cultural traits lead to detectable changes in symbolic codes expressed by associations of ornaments on the human body. Here we use personal ornaments to document changes in cultural geography during the Mesolithic-Neolithic transition. We submitted a binary matrix of 224 bead-types found at 212 European Mesolithic and 222 Early Neolithic stratigraphic units to a series of spatial and multivariate analyses. Our results reveal consistent diachronic and geographical trends in the use of personal ornaments during the Neolithisation. Adoption of novel bead-types combined with selective appropriation of old attires by incoming farmers is identified in Southern and Central Europe while cultural resistance leading to the nearly exclusive persistence of indigenous personal ornaments characterizes Northern Europe. We argue that this pattern reflects two distinct cultural trajectories with different potential for gene flow. PMID:25853888

An in silico pan-genomic probe for the molecular traits behind Lactobacillus ruminis gut autochthony.

As an ecological niche, the mammalian intestine provides the ideal habitat for a variety of bacterial microorganisms. Purportedly, some commensal genera and species offer a beneficial mix of metabolic, protective, and structural processes that help sustain the natural digestive health of the host. Among these sort of gut inhabitants is the Gram-positive lactic acid bacterium Lactobacillus ruminis, a strict anaerobe with both pili and flagella on its cell surface, but also known for being autochthonous (indigenous) to the intestinal environment. Given that the molecular basis of gut autochthony for this species is largely unexplored and unknown, we undertook a study at the genome level to pinpoint some of the adaptive traits behind its colonization behavior. In our pan-genomic probe of L. ruminis, the genomes of nine different strains isolated from human, bovine, porcine, and equine host guts were compiled and compared for in silico analysis. For this, we conducted a geno-phenotypic assessment of protein-coding genes, with an emphasis on those products involved with cell-surface morphology and anaerobic fermentation and respiration. We also categorized and examined the core and accessory genes that define the L. ruminis species and its strains. Here, we made an attempt to identify those genes having ecologically relevant phenotypes that might support or bring about intestinal indigenousness.

The genetic structure of the indigenous hunter-gatherer peoples of southern Africa, the oldest known lineage of modern human, is important for understanding human diversity. Studies based on mitochondrial1 and small sets of nuclear markers2 have shown that these hunter-gatherers, known as Khoisan, San, or Bushmen, are genetically divergent from other humans1,3. However, until now, fully sequenced human genomes have been limited to recently diverged populations4–8. Here we present the complete genome sequences of an indigenous hunter-gatherer from the Kalahari Desert and a Bantu from southern Africa, as well as protein-coding regions from an additional three hunter-gatherers from disparate regions of the Kalahari. We characterize the extent of whole-genome and exome diversity among the five men, reporting 1.3 million novel DNA differences genome-wide, including 13,146 novel amino acid variants. In terms of nucleotide substitutions, the Bushmen seem to be, on average, more different from each other than, for example, a European and an Asian. Observed genomic differences between the hunter-gatherers and others may help to pinpoint genetic adaptations to an agricultural lifestyle. Adding the described variants to current databases will facilitate inclusion of southern Africans in medical research efforts, particularly when family and medical histories can be correlated with genome-wide data.

Enteral tube feeding is widely used to maintain nutrition for elderly adults with eating difficulties, but its long-term use alters the environment of the oral ecosystem. This study characterized the tongue microbiota of tube-fed elderly adults by analyzing the 16S rRNA gene. The terminal restriction fragment length polymorphism (T-RFLP) profiles of 44 tube-fed subjects were compared with those of 54 subjects fed orally (average age, 86.4 ± 6.9 years). Bar-coded pyrosequencing data were also obtained for a subset of the subjects from each group (15 tube-fed subjects and 16 subjects fed orally). The T-RFLP profiles demonstrated that the microbiota of the tube-fed subjects was distinct from that of the subjects fed orally (permutational multivariate analysis of variance [perMANOVA], P < 0.001). The pyrosequencing data revealed that 22 bacterial genera, including Corynebacterium, Peptostreptococcus, and Fusobacterium, were significantly more predominant in tube-fed subjects, whereas the dominant genera in the subjects fed orally, such as Streptococcus and Veillonella, were present in much lower proportions. Opportunistic pathogens rarely detected in the normal oral microbiota, such as Corynebacterium striatum and Streptococcus agalactiae, were often found in high proportions in tube-fed subjects. The oral indigenous microbiota is disrupted by the use of enteral feeding, allowing health-threatening bacteria to thrive.

Objective To develop and validate a behavioral coding measure, the Children's Behavior Coding System-PACU (CBCS-P), for children's distress and nondistress behaviors while in the postanesthesia recovery unit. Methods A multidisciplinary team examined videotapes of children in the PACU and developed a coding scheme that subsequently underwent a refinement process (CBCS-P). To examine the reliability and validity of the coding system, 121 children and their parents were videotaped during their stay in the PACU. Participants were healthy children undergoing elective, outpatient surgery and general anesthesia. The CBCS-P was utilized and objective data from medical charts (analgesic consumption and pain scores) were extracted to establish validity. Results Kappa values indicated good-to-excellent (κ's > .65) interrater reliability of the individual codes. The CBCS-P had good criterion validity when compared to children's analgesic consumption and pain scores. Conclusions The CBCS-P is a reliable, observational coding method that captures children's distress and nondistress postoperative behaviors. These findings highlight the importance of considering context in both the development and application of observational coding schemes. PMID:22167123

intimate partner violence is a significant global health problem but remains largely hidden. Understanding decisions about whether or not to disclose violence in response to routine enquiry in health settings can inform safe and responsive systems. Elevated rates of violence and systematic disadvantage found among Indigenous women globally, can impact on their decisions to disclose violence. This study aimed to test, among Indigenous women, a model for decisions on whether to disclose intimate partner violence in the context of antenatal routine screening. we employed Qualitative Configurative Analysis, a method developed for the social sciences to study complex phenomena with intermediate sample sizes. Data were drawn from single semi- structured interviews with Indigenous women 28+ weeks pregnant attending antenatal care. Interviews addressed decisions to disclose recent intimate partner violence in the context of routine enquiry during the antenatal care. Interview transcripts were binary coded for conditions identified a priori from the model being tested and also from themes identified within the current study and analysed using Qualitative Configurative Analysis to determine causal conditions for the outcome of disclosure or non-disclosure of violence experienced. five Aboriginal and Maternal Infant Health Services (two urban and three regional), and one mainstream hospital, in New South Wales, Australia. indigenous women who had experienced partner violence in the previous year and who had been asked about this as part of an antenatal booking-in visit. Of the 12 participants six had elected to disclose their experience of violence to the midwife, and six had chosen not to do so. pathways to disclosure and non-disclosure were mapped using Qualitative Configurative Analysis. Conditions relevant to decisions to disclose were similar to the conditions for non-Aboriginal women found in our earlier study. Unique to Aboriginal women's decisions to disclose abuse was cultural safety. Cultural safety included elements we titled: Borrowed trust, Build the relationship first, Come at it slowly and People like me are here. The absence of cultural safety Its absence was also a factor in decisions not to disclose experiences of violence by this group of women. cultural safety was central to Indigenous women's decision to disclose violence and processes for creating safety are identified. Other forms of safety which influenced disclosure included: safety from detection by the abuser; safety from shame; and safety from institutional control. Disclosure was promoted by direct asking by the midwife and a perception of care. Non-disclosure was associated with a lack of care and a lack of all four types of safety. Experiences of institutional racism were associated with Indigenous women's perceived risk of control by others, particularly child protection services. policies to ask abuse questions at first visits and models where continuity of care is not maintained, are problematic for Aboriginal women, among whom relationship building is important as is ample warning about questions to be asked. Strategies are needed to build cultural safety to counter widespread racism and promote safe opportunities for Indigenous women to disclose intimate partner violence and receive support. Elements of cultural safety are necessary for vulnerable or marginalised populations to fully utilise available health services. Crown Copyright © 2016. Published by Elsevier Ltd.

Hospitalisations are associated with ambient temperature, but little is known about responses in population sub-groups. In this study, heat responses for Indigenous and non-Indigenous people in two age groups were examined for two categories of cardiac diseases using daily hospital admissions from five Northern Territory hospitals (1992–2011). Admission rates during the hottest five per cent of days and the coolest five per cent of days were compared with rates at other times. Among 25–64 year olds, the Indigenous female population was more adversely affected by very hot days than the non-Indigenous female population, with admission rates for ischaemic heart disease (IHD) increasing by 32%. People older than 65 were more sensitive to cold, with non-Indigenous male admissions for heart failure increasing by 64%, and for IHD by 29%. For older Indigenous males, IHD admissions increased by 52% during cold conditions. For older non-Indigenous females, increases in admissions for heart failure were around 50% on these cold days, and 64% for older Indigenous females. We conclude that under projected climate change conditions, admissions for IHD amongst younger Indigenous people would increase in hot conditions, while admissions among elderly people during cold weather may be reduced. The responses to temperature, while showing significant relationships across the Northern Territory, may vary by region. These variations were not explored in this assessment. PMID:24531121

We studied the impacts of colonists, two groups of indigenous residents (Miskitu and Mayangna), and management by the Nicaraguan Ministry of Environment and Natural Resources (MARENA) on the forest of the Bosawas International Biosphere Reserve. Indigenous people and colonists subsist on the natural resources of the reserve, and MARENA is responsible for protecting the area from colonization and illicit exploitation. Using geostatistical procedures and Landsat images at three different time periods, we compared per capita deforestation and boundary stabilization in areas with colonists and areas with indigenous peoples. We also examined whether the Mayangna deforested less than the Miskitu and whether the Nicaraguan government has effectively defended the Bosawas boundary against the advance of the agricultural frontier. In addition, we analyzed the current distribution of land uses within the reserve and its contiguous indigenous areas with a supervised classification of current land cover. Indigenous demarcations protected the forest successfully, whereas the Bosawas boundary itself did not inhibit colonization and consequent deforestation. Indigenous farmers deforested significantly less per capita than colonists, and the two indigenous groups in Bosawas did not differ significantly in their effects on the forest. Our results show that indigenous common-property institutions and indigenous defense of homeland have been powerful factors in protecting the forests of Bosawas and that the difficult evolution of a nested cross-scale governance system in Bosawas-under pressure from indigenous peoples-is probably the key to the forest's survival thus far.

There is a global increase in chronic, degenerative illnesses that require long-term intervention and support as a result of the aging population. The majority of support needs are met by informal family caregivers. While there have been three decades of research focusing on caregivers in general, the extent to which research has focused on Indigenous caregivers is unclear. Worldwide, Indigenous peoples face severe economic and health disadvantages that may make them even more vulnerable to the negative aspects of informal caregiving. The current systematic review aimed to synthesize the extant literature on Indigenous caregiver functioning and the interventions that are efficacious in alleviating Indigenous caregiver distress. Systematic review Inclusion criteria were peer-reviewed quantitative studies examining Indigenous caregiver functioning or evaluating Indigenous caregiver interventions. 1172 unique records were located in the final search undertaken; only 7 articles, representing 6 unique studies, met the full inclusion criteria. Most studies contained numerous methodological weaknesses that compromised the reliability and validity of findings. Available studies suggest poor health and high burden among Indigenous relative to non-Indigenous caregivers. However, high levels of positive aspects of caregiving were reported in one study. A single intervention study suggests that poor health outcomes among Indigenous caregivers can be alleviated, though the quality and focus of this study was sub-optimal. Overall, there is very little quality evidence around Indigenous caregiver functioning. Future research in this area would benefit from greater adherence to the standards of research that contribute to a strong and reliable evidence base.

The burden of tuberculosis (TB) in the estimated 370 million indigenous peoples worldwide is unknown. To conduct a literature review to summarize the TB burden in indigenous peoples, identify gaps in current knowledge, and provide the foundation for a research agenda prioritizing indigenous health within TB control. A systematic literature review identified articles published between January 1990 and November 2011 quantifying TB disease burden in indigenous populations worldwide. Among the 91 articles from 19 countries included in the review, only 56 were from outside Australia, Canada, New Zealand and the United States. The majority of the studies showed higher TB rates among indigenous groups than non-indigenous groups. Studies from the Amazon generally reported the highest TB prevalence and incidence, but select populations from South-East Asia and Africa were found to have similarly high rates of TB. In North America, the Inuit had the highest reported TB incidence (156/100000), whereas the Metis of Canada and American Indians/Alaska Natives experienced rates of <10/100000. New Zealand's Maori and Pacific Islanders had higher TB incidence rates than Australian Aborigines, but all were at greater risk of developing TB than non-indigenous groups. Where data exist, indigenous peoples were generally found to have higher rates of TB disease than non-indigenous peoples; however, this burden varied greatly. The paucity of published information on TB burden among indigenous peoples highlights the need to implement and improve TB surveillance to better measure and understand global disparities in TB rates.

Indigenous populations have high rates of disease and premature mortality. Most Indigenous communities are young, and adolescence (age 10-24 years) provides great opportunities for population health gain. However, the absence of a comprehensive account of Indigenous adolescents' health has been a barrier to effective policy. We aimed to report a national health profile for Indigenous adolescents in Australia. We undertook a systematic synthesis of population data to report the health and wellbeing of Indigenous adolescents in Australia. A reporting framework for Indigenous adolescent health in Australia was defined to measure health outcomes, health risks, and sociocultural determinants. Available data (primary data from national surveys and administrative datasets, and available published data) were mapped against the defined reporting framework, and the quality graded, with the highest quality data selected to report a health profile for Indigenous adolescents. Comparison with non-Indigenous adolescents was made where possible, and estimates (disaggregated by age, sex, and remoteness) were reported as relative risks. A national advisory group (six Indigenous young people, three Indigenous adult community members, three researchers, three policy makers, and two service providers, all aged ≥16 years) provided input about the reporting framework, interpretation of findings, and policy recommendations. Data were available for 184 (79%) of 234 elements of the reporting framework. All-cause mortality for Indigenous adolescents (70 per 100 000) was more than twice that of non-Indigenous adolescents, with about 60% of deaths due to intentional self-harm and road traffic injury. 80% of all deaths among Indigenous adolescents were considered as potentially avoidable in the current health system. Communicable diseases (particularly sexually transmitted infections) were leading contributors to morbidity. Almost a third of Indigenous adolescents aged 18-24 years reported high levels of psychological distress (twice the non-Indigenous rate). There was an excess burden of mental disorders and substance use, alongside emerging type 2 diabetes and ischaemic heart disease. Additionally, there were excess intentional and unintentional injuries. Many aspects of this health profile differed markedly from that of non-Indigenous adolescents: rates of acute rheumatic fever, pneumococcal infection, gonorrhoea, and type 2 diabetes resulting in admission to hospital were ten times higher; rates of assault and childbirth in those aged 15-19 years were five times higher; whereas rates of eating disorders, melanoma and other skin cancers, and anaphylaxis were significantly lower. Risks for future ill-health were common; 43% of 15-24 year olds were current tobacco smokers and about 45% had high body mass (overweight or obese). Disadvantage across sociocultural health determinants also emerged, particularly around education. Despite Australia's adolescents having one of the best health profiles globally, Indigenous adolescents have largely been left behind. Adequate responses will require intersectoral actions, including a health system responsive to the needs of Indigenous adolescents. Without a specific focus on adolescents, Australia will not redress Indigenous health inequalities.

"We have always lived here": indigenous movements, citizenship and poverty in Argentina.

PubMed

vom Hau, Matthias; Wilde, Guillermo

2010-01-01

This article explores the nexus between indigenous mobilisation, citizenship, and poverty in Argentina. A subnational comparison of land struggles among the Diaguita Calchaqu in Tucumn and the Mbya Guaran in Misiones shows that changing global and national opportunity structures, most prominently a new multicultural citizenship regime, set the stage for indigenous mobilisation. In turn, local transformations of capitalist development motivate indigenous mobilising efforts, whereas leadership patterns and state-movement relations shape the capacity to mobilise. Diaguita and Mbya mobilisation reveals that indigenous movements play a central role in the activation of formal citizenship rights and the contestation of dominant notions of poverty. At the same time, the current design of multicultural citizenship and the adverse socioeconomic incorporation of indigenous communities also counteract indigenous mobilising efforts in Argentina.

Prevalence of anemia and associated factors among indigenous children in Brazil: results from the First National Survey of Indigenous People’s Health and Nutrition

PubMed Central

2013-01-01

Background Anemia is the most prevalent nutritional deficiency globally, affecting about a quarter of the world population. In Brazil, about one-fifth of children under five years of age are anemic. Previous case studies indicate prevalence rates much higher among indigenous peoples in the country. The First National Survey of Indigenous People’s Health and Nutrition in Brazil, conducted in 2008–2009, was the first survey based on a nationwide representative sample to study the prevalence of anemia and associated factors among indigenous children in Brazil. Methods The survey assessed the health and nutritional status of indigenous children < 5 years of age based on a representative sample of major Brazilian geopolitical regions. A stratified probabilistic sampling was carried out for indigenous villages. Within villages, children < 5 years of age in sampled households were included in the study. Prevalence rates of anemia were calculated for independent variables and hierarchical multivariate analysis were conducted to assess associations. Results Evaluation of hemoglobin levels was conducted for 5,397 children (88.1% of the total sample). The overall prevalence of anemia was 51.2%. Higher risk of presenting anemia was documented for boys, lower maternal schooling, lower household socioeconomic status, poorer sanitary conditions, presence of maternal anemia, and anthropometric deficits. Regional differences were observed, with the highest rate being observed in the North. Conclusions The prevalence rates of anemia in indigenous children were approximately double than those reported for non-indigenous Brazilian children in the same age group. Similarly notable differences in the occurrence of anemia in indigenous and non-indigenous children have been reported for other countries. Deeper knowledge about the etiology of anemia in indigenous children in Brazil is essential to its proper treatment and prevention. PMID:23714275

Elevated reporting of unprotected anal intercourse and injecting drug use but no difference in HIV prevalence among Indigenous Australian men who have sex with men compared with their Anglo-Australian peers.

Although half of the HIV notifications among Aboriginal and Torres Strait Islander people ('Indigenous Australians') are attributed to homosexual transmission, there has been little research examining sexual and drug use risk practices among Indigenous Australian men who have sex with men (MSM). Respondents were Indigenous Australian (n=1278) and Anglo-Australian men (n=24002) participating in the routine cross-sectional Gay Community Periodic Surveys conducted in Australia from 2007 to 2011. Sociodemographic characteristics, sexual risk practices, drug use, HIV testing and HIV status of Indigenous and Anglo-Australian men were compared and evaluated to discover whether Indigenous status was independently associated with HIV risk practices. Although an equivalent proportion of Indigenous and Anglo-Australian men reported being HIV-positive (9.6%), Indigenous MSM were more likely to report unprotected anal intercourse with casual partners in the previous 6 months (27.9% v. 21.5%; Adjusted odds ratio (AOR)=1.29, 95% confidence interval (CI): 1.11-1.49). Indigenous men were more likely than Anglo-Australian men to report use of several specific drugs and twice as likely to report injecting drug use in the previous 6 months (8.8% v. 4.5%; AOR=1.43, 95% CI: 1.11-1.86). Despite a higher proportion of Indigenous men reporting sexual and drug use practices that increase the risk of HIV transmission, there were no differences in the HIV status of Indigenous and Anglo-Australian men. However, the elevated rates of risk practices suggest that Indigenous MSM should remain a focus for HIV prevention, care and support.

Drug and alcohol use and treatment for Australian Indigenous and non-Indigenous prisoners: demand reduction strategies.

The purpose of this paper is to compare the use of drugs and alcohol by Indigenous and non-Indigenous prisoners and examine relevant treatment in Australian prisons. Prison authorities were surveyed about alcohol and drug use by prisoners prior to and during imprisonment and drug and alcohol treatment programs in prison. The literature was review for information on alcohol and drug use and treatment in Australian prisons. In 2009, over 80 percent of Indigenous and non-Indigenous inmates smoked. Prior to imprisonment, many Indigenous and non-Indigenous inmates drank alcohol at risky levels (65 vs 47 percent) and used illicit drugs (over 70 percent for both groups). Reports of using heroin (15 vs 21 percent), ATS (21 vs 33 percent), cannabis (59 vs 50 percent) and injecting (61 vs 53 percent) were similarly high for both groups. Prison-based programs included detoxification, Opioid Substitution Treatment, counselling and drug free units, but access was limited especially among Indigenous prisoners. Drug and alcohol use was a significant issue in Australian prisons. Prisoners were over five times more likely than the general population to have a substance use disorder. Imprisonment provides an important opportunity for rehabilitation for offenders. This opportunity is especially relevant to Indigenous prisoners who were more likely to use health services when in prison than in the community and given their vast over representations in prison populations. Given the effectiveness of treatment in reducing re-offending rates, it is important to expand drug treatment and especially culturally appropriate treatment programs for Indigenous inmates. Very little is known about Indigenous specific drug and alcohol programs in Australian prisons.

Indigenous Australians have higher rates of cardiovascular disease and co-morbidities compared to their non-Indigenous counterparts. We sought to evaluate whether Indigenous status per se portends a worse prognosis following isolated coronary artery bypass grafting (CABG). The outcomes of 778 Indigenous Australians (55±10 years; 32% female) enrolled in the Australian and New Zealand Society of Cardiac and Thoracic Surgeons registry were compared to 36,124 non-Indigenous Australians (66±10 years; 21% female) following isolated CABG. In a secondary analysis, patients were propensity-matched by age, gender, renal function, diabetes, and ejection fraction (778 individuals in each group). Indigenous Australians were younger and more likely to be female, current smokers, to have diabetes, hypertension, renal impairment, heart failure, and previous CABG (all p<0.04). Indigenous patients had fewer bypasses with arterial conduits (including less internal mammary artery use), and a higher number of distal vein anastomoses (p<0.001). Post-operative bleeding rates were higher in indigenous patients (p=0.001). However, in-hospital and 30-day all-cause mortality, and rates of 30-day readmission were similar between both groups, though cardiac mortality was higher in the Indigenous cohort (1.5% vs. 0.8%, p=0.02). With propensity-matching, rates of post-operative complications were similar amongst the two groups, with the exception of bleeding, which remained higher in Indigenous Australians (p=0.03). Despite procedural differences and higher rates of baseline co-morbidities, Indigenous Australians do not have worse short-term outcomes following isolated CABG. Given the higher rates of baseline co-morbidities and lower rates of arterial conduit use, it will be essential to determine long-term outcomes. This article is protected by copyright.

The aim of this work was to understand the pattern and outcomes for heart failure (HF)-related hospitalization among Indigenous and non-Indigenous patients living in Central Australia. A retrospective analysis of administrative data for patients presenting with a primary or secondary diagnosis of HF to Central Australia's Alice Springs Hospital during 2008-2012 was performed. The population rate of admission and subsequent outcomes (including mortality and readmission) during the 5-year study period were examined. A total of 617 patients, aged 55.8 ± 17.5 years and 302 (49%) female constituted the study cohort. The 446 Indigenous patients (72%) were significantly younger (50.8 ± 15.9 vs 68.7 ± 14.9; P < .001) and clinically more complex compared with the non-Indigenous patients. Annual prevalence of any HF hospitalization was markedly higher in the Indigenous population (1.9%, 95% CI 1.7-2.1) compared with the non-Indigenous population (0.5%, 95% CI 0.4-0.6); the greatest difference being for women. Overall, non-Indigenous patients had poorer outcomes and were significantly more likely to die (P < .0001), but this was largely driven by age differences. Alternatively, Indigenous patients were significantly more likely to have a higher number of hospitalizations, although indigeneity was not a predictor for 30- or 365-day rehospitalization from the index admission. The pattern of HF among Indigenous Australians in Central Australia is characterized by a younger population with more clinically complex cases and greater health care utilization.

Indigenous communities in Taiwan shoulder a disproportionate burden of unintentional injury fatalities. We compare unintentional injury mortality rate trends among Taiwan's indigenous communities and the general population from 2002 to 2013, and evaluate potential impact of a community-based injury prevention programme on indigenous unintentional injury death rates. Standardised and crude unintentional injury mortality rates were obtained from Taiwan government reports. Segmented linear regression was used to estimate and compare unintentional injury mortality rate trends before and after the intervention. Between 2002 and 2013, unintentional injury mortality rates among Taiwan's indigenous population significantly declined by about 4.5 deaths per 100 000 each year (p<0.0001). During that time, the unintentional injury mortality rate ratio between indigenous Taiwanese and the general population significantly decreased by approximately 1% each successive year (p=0.02). However, we were unable to detect evidence that the 'Healthy and Safe Tribe' programme was associated with a statistically significant decrease in the unintentional injury mortality rate trend among indigenous persons (p=0.81). Taiwanese indigenous communities remain at significantly higher risk of unintentional injury death, though the gap may be slowly narrowing. We found no evidence that the 'Healthy and Safe Tribe' indigenous injury-prevention programme significantly contributed to the nationwide decline in unintentional injury mortality among indigenous Taiwanese communities from 2009 to 2013. Future interventions to address the disproportionate burden of unintentional injury fatalities among indigenous Taiwanese should consider interventions with wider coverage of the indigenous population, and complementing grass roots led community-based interventions with structural policy interventions as well. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Efforts to build empirical evidence for the protective effects of Indigenous cultural factors on psychological health have yielded mixed findings. We examine the interplay of previously hypothesized culturally relevant risk (discrimination, historical loss) and protective (spiritual activities) factors among Indigenous people. The sample includes 569 Indigenous adolescents (M age = 17.23, SD = 0.88; 51.0% girls) and 563 Indigenous adult caregivers (M age = 44.66, SD = 9.18; 77.4% women). Our central finding was that indigenous spirituality was associated with poorer psychological outcomes across several domains (depressive symptoms, anger, anxiety, somatization and interpersonal difficulties), but observed effects were attenuated once perceived discrimination and historical losses were added to statistical models. Thus, consideration of relevant stressors drastically changed our conclusions, underscoring the uncertain dynamics through which specific Indigenous cultural factors impact mental health. Researchers should work in collaboration with Indigenous communities to improve measurement and empirical investigation of these complex constructs. PMID:28138417

Authorship in IPCC AR5 and its implications for content: climate change and Indigenous populations in WGII.

PubMed

Ford, James D; Vanderbilt, Will; Berrang-Ford, Lea

This essay examines the extent to which we can expect Indigenous Knowledge, understanding, and voices on climate change ('Indigenous content') to be captured in WGII of the IPCC Fifth Assessment Report (AR5), based on an analysis of chapter authorship. Reviewing the publishing history of 309 chapter authors (CAs) to WGII, we document 9 (2.9%) to have published on climate change and Indigenous populations and involved as authors in 6/30 chapters. Drawing upon recent scholarship highlighting how authorship affect structure and content of assessment reports, we argue that, unaddressed, this will affect the extent to which Indigenous content is examined and assessed. While it is too late to alter the structure of AR5, there are opportunities to prioritize the recruitment of contributing authors and reviewers with expertise on Indigenous issues, raise awareness among CAs on the characteristics of impacts, adaptation, and vulnerability faced by Indigenous peoples, and highlight how Indigenous perspectives can help broaden our understanding of climate change and policy interventions.

Previously there has been commitment to the idea that Indigenous curricula should be taught by Indigenous academic staff, whereas now there is increasing recognition of the need for all academic staff to have confidence in enabling Indigenous cultural competency for nursing and other health professional students. In this way, Indigenous content can be threaded throughout a curriculum and raised in many teaching and learning situations, rather than being siloed into particular subjects and with particular staff. There are many sensitivities around this change, with potential implications for Indigenous and non-Indigenous students and staff, and for the quality of teaching and learning experiences. This paper reports on a collaborative process that was used to reconceptualise how Indigenous health care curricula would be positioned throughout a programme and who would or could work with students in this area. Effective leadership, establishing a truly collaborative environment, acknowledging fears and perceived inadequacies, and creating safe spaces for sharing and learning were crucial in effecting this change.

Ethnic Differences in the Quality of the Interview Process and Implications for Survey Analysis: The Case of Indigenous Australians

PubMed Central

Perales, Francisco

2015-01-01

Comparable survey data on Indigenous and non-Indigenous Australians are highly sought after by policymakers to inform policies aimed at closing ethnic socio-economic gaps. However, collection of such data is compromised by group differences in socio-economic status and cultural norms. We use data from the Household, Income and Labour Dynamics in Australia Survey and multiple-membership multilevel regression models that allow for individual and interviewer effects to examine differences between Indigenous and non-Indigenous Australians in approximate measures of the quality of the interview process. We find that there are both direct and indirect ethnic effects on different dimensions of interview process quality, with Indigenous Australians faring worse than non-Indigenous Australians in all outcomes ceteris paribus . This indicates that nationwide surveys must feature interview protocols that are sensitive to the needs and culture of Indigenous respondents to improve the quality of the survey information gathered from this subpopulation.

Indigenous community health workers are part of a strategy developed by Brazil in the last two decades to promote a special healthcare model for indigenous peoples. Their role is designed to deal with various aspects of the special health policy, including the link between the heath team and the community and mediation between scientific and indigenous medical knowledge. Despite a significant increase in the number of indigenous community health workers in recent years, an evaluation of their responsibilities and contributions to the success of special care had not been conducted previously. This article, based on a literature review and original research by the authors, analyzes the role of the indigenous community health workers vis-à-vis their training and participation in health teams in different contexts in Brazil. Considering the importance assigned to the role of indigenous community health workers, this analysis reveals various ambiguities and contradictions that hinder both their performance and their potential contribution to the special health services.

In recent years, Thai indigenous chickens have increasingly been bred as an alternative in Thailand poultry market. Due to their popularity, there is a clear need to improve the underlying quality and productivity of these chickens. Studying chicken genetic variation can improve the chicken meat quality as well as conserving rare chicken species. To begin with, a minimal set of molecular markers that can characterize the Thai indigenous chicken breeds is required. Using AFLP-PCR, 30 single nucleotide polymorphisms (SNPs) from Thai indigenous chickens were obtained by DNA sequencing. From these SNPs, we genotyped 465 chickens from 7 chicken breeds, comprising four Thai indigenous chicken breeds--Pradhuhangdum (PD), Luenghangkhao (LK), Dang (DA) and Chee (CH), one wild chicken--the red jungle fowls (RJF), and two commercial chicken breeds--the brown egg layer (BL) and commercial broiler (CB). The chicken genotypes reveal unique genetic structures of the four Thai indigenous chicken breeds. The average expected heterozygosities of PD=0.341, LK=0.357, DA=0.349 and CH=0.373, while the references RJF= 0.327, CB=0.324 and BL= 0.285. The F(ST) values among Thai indigenous chicken breeds vary from 0.051 to 0.096. The F(ST) values between the pairs of Thai indigenous chickens and RJF vary from 0.083 to 0.105 and the FST values between the Thai indigenous chickens and the two commercial chicken breeds vary from 0.116 to 0.221. A neighbour-joining tree of all individual chickens showed that the Thai indigenous chickens were clustered into four groups which were closely related to the wild RJF but far from the commercial breeds. Such commercial breeds were split into two closely groups. Using genetic admixture analysis, we observed that the Thai indigenous chicken breeds are likely to share common ancestors with the RJF, while both commercial chicken breeds share the same admixture pattern. These results indicated that the Thai indigenous chicken breeds may descend from the same ancestors. These indigenous chicken breeds were more closely related to red jungle fowls than those of the commercial breeds. These findings showed that the proposed SNP panel can effectively be used to characterize the four Thai indigenous chickens.

Indigenous Australians have poorer outcomes from cancer for a variety of reasons including poorer participation in screening programs, later diagnosis, higher rates of cancer with poor prognosis and poorer uptake and completion of treatment. Cancer prevention and support for people with cancer is part of the core business of the State and Territory Cancer Councils. To support sharing of lessons learned, this paper reports an environmental scan undertaken in 2010 in cancer councils (CCs) nationwide that aimed to support Indigenous cancer control. The methods replicated the approach used in a 2006 environmental scan of Indigenous related activity in CCs. The Chief Executive Officer of each CC nominated individuals for interview. Interviews explored staffing, projects, programs and activities to progress cancer control issues for Indigenous Australians, through phone or face-to-face interviews. Reported initiatives were tabulated using predetermined categories of activity and summaries were returned to interviewees, the Aboriginal and Torres Strait Islander Subcommittee and Chief Executive Officers for verification. All CCs participated and modest increases in activity had occurred in most states since 2006 through different means. Indigenous staff numbers were low and no Indigenous person had yet been employed in smaller CCs; no CC had an Indigenous Board member and efforts at capacity building were often directed outside of the organisation. Developing partnerships with Indigenous organisations were ongoing. Acknowledgement and specific mention of Indigenous people in policy was increasing. Momentum increased following the establishment of a national subcommittee which increased the profile of Indigenous issues and provided collegial and practical support for those committed to reducing Indigenous cancer disparities. Government funding of "Closing the Gap" and research in the larger CCs have been other avenues for increasing knowledge and activity in Indigenous cancer control. This environmental scan measured progress, allowed sharing of information and provided critical assessment of progress across areas of importance for increasing Indigenous cancer control. Structured examination of policies, institutional support systems, programs and interventions is a useful means of highlighting opportunities for progress with minority groups relevant for many organisations. Progress has occurred with momentum likely to increase in the future and benefit from commitment to long-term monitoring and sharing of achievements.

Effective knowledge translation (KT) is critical to implementing program and policy changes that require shared understandings of knowledge systems, assumptions, and practices. Within mainstream research institutions and funding agencies, systemic and insidious inequities, privileges, and power relationships inhibit Indigenous peoples' control, input, and benefits over research. This systematic review will examine literature on KT initiatives in Indigenous health research to help identify wise and promising Indigenous KT practices and language in Canada and abroad. Indexed databases including Aboriginal Health Abstract Database, Bibliography of Native North Americans, CINAHL, Circumpolar Health Bibliographic Database, Dissertation Abstracts, First Nations Periodical Index, Medline, National Indigenous Studies Portal, ProQuest Conference Papers Index, PsycInfo, Social Services Abstracts, Social Work Abstracts, and Web of Science will be searched. A comprehensive list of non-indexed and grey literature sources will also be searched. For inclusion, documents must be published in English; linked to Indigenous health and wellbeing; focused on Indigenous people; document KT goals, activities, and rationale; and include an evaluation of their KT strategy. Identified quantitative, qualitative, and mixed methods' studies that meet the inclusion criteria will then be appraised using a quality appraisal tool for research with Indigenous people. Studies that score 6 or higher on the quality appraisal tool will be included for analysis. This unique systematic review involves robust Indigenous community engagement strategies throughout the life of the project, starting with the development of the review protocol. The review is being guided by senior Indigenous researchers who will purposefully include literature sources characterized by Indigenous authorship, community engagement, and representation; screen and appraise sources that meet Indigenous health research principles; and discuss the project with the Indigenous Elders to further explore the hazards, wisdom, and processes of sharing knowledge in research contexts. The overall aim of this review is to provide the evidence and basis for recommendations on wise practices for KT terminology and research that improves Indigenous health and wellbeing and/or access to services, programs, or policies that will lead to improved health and wellbeing.

Inaccuracies in the identification of Indigenous status and the collection of and access to vital statistics data impede the strategic implementation of evidence-based public health initiatives to reduce avoidable deaths. The impact of colonization and subsequent government initiatives has been commonly observed among the Indigenous peoples of Australia, Canada, New Zealand, and the United States. The quality of Indigenous data that informs mortality statistics are similarly connected to these distal processes, which began with colonization. We discuss the methodological and technical challenges in measuring mortality for Indigenous populations within a historical and political context, and identify strategies for the accurate ascertainment and inclusion of Indigenous people in mortality statistics.

There is growing recognition among health researchers and funders that the wider benefits of research such as economic, social and health impacts ought to be assessed and valued alongside academic outputs such as peer-reviewed papers. Research translation needs to increase and the pathways to impact ought to be more transparent. These processes are particularly pertinent to the Indigenous health sector given continued concerns that Indigenous communities are over-researched with little corresponding improvement in health outcomes. This paper describes the research protocol of a mixed methods study to apply FAIT (Framework to Assess the Impact from Translational health research) to the Centre for Research Excellence in Integrated Quality Improvement (CRE-IQI). FAIT will be applied to five selected CRE-IQI Flagship projects to encourage research translation and assess the wider impact of that research. Phase I will develop a modified programme logic model for each Flagship project including identifying process, output and impact metrics so progress can be monitored. A scoping review will inform potential benefits. In phase II, programme logic models will be updated to account for changes in the research pathways over time. Audit and feedback will be used to encourage research translation and collect evidence of achievement of any process, output and interim impacts. In phase III, three proven methodologies for measuring research impact-Payback, economic assessment and narratives-will be applied. Data on the application of FAIT will be collected and analysed to inform and improve FAIT's performance. This study is funded by a nationally competitive grant (ID 1078927) from the Australian National Health and Medical Research Council. Ethics approval was obtained from the University of Newcastle's Human Research Ethics Committee (ID: H-2017-0026). The results from the study will be presented in several peer-reviewed publications, through conference presentations and via social media. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2016-01-01

This article explores the application of two-eyed seeing in the first year of a three-year study about the effectiveness of cultural interventions in First Nations alcohol and drug treatment in Canada. Two-eyed seeing is recognized by Canada’s major health research funder as a starting point for bringing together the strengths of Indigenous and Western ways of knowing. With the aim of developing a culture-based measurement tool, our team carried out an Indigenous-centred research process with our interpretation of two-eyed seeing as a guiding principle. This enabled us to engage in a decolonizing project that prioritized Indigenous methodologies and ways of knowing and knowledge alongside those of Western science. By concentrating on Indigenous governance in the research process, our project supported efforts at Indigenous cultural renewal. Two illustrations are offered, our team’s reconceptualization of Western derived understandings of data collection through Indigenous storytelling and our research grant timeframe with Indigenous knowledge gardening. This article contributes to the Indigenous research and policy literature which is lacking documentation about how Indigenous communities and research teams are benefitting from two-eyed seeing.

Coronial Practice, Indigeneity and Suicide

PubMed Central

Tait, Gordon; Carpenter, Belinda; Jowett, Stephanie

2018-01-01

All available data suggest that, like many other Indigenous peoples, Australian Aborigines are significantly more likely to kill themselves than are non-Aboriginal Australians. This statistical disparity is normally positioned an objective, ontological and undeniable social fact, a fact best explained as a function of endemic community disadvantage and disenfranchisement. This research explores the possibility that higher-than-normal Aboriginal suicide rates may also be a function of coronial decision-making practices. Based upon in-depth interviews with 32 coroners from across Australia, the following conclusions emerged from the data. First, coroners have differing perceptions of Indigenous capacity, and are less likely to have concerns about intent when the suicide is committed by an Indigenous person. Second, coroners have identified divergent scripts of Indigenous suicide, particularly its spontaneity and public location, and this supports rather than challenges, a finding of suicide. Third, the coronial perception of Indigenous life is a factor which influences a suicide determination for Indigenous deaths. Finally, the low level of Indigenous engagement with the coronial system, and the unlikelihood of a challenge to the finding of suicide by Indigenous families, means that a coronial determination of suicide is more likely.

Reconciling community-based Indigenous research and academic practices: Knowing principles is not always enough.

PubMed

Morton Ninomiya, Melody E; Pollock, Nathaniel J

2017-01-01

Historically, Indigenous health research in Canada has failed to engage Indigenous peoples and communities as primary stakeholders of research evidence. Increasingly, research ethics and methodologies are being positioned as tools for Indigenous self-determination. In response, mainstream institutions have developed new ethical principles for research involving Indigenous people. While these transformations are necessary steps towards re-orienting research practices, they are not prescriptive. In this paper, we make visible three dilemmas from a case study in which Indigenous health research frameworks provided limited guidance or were unclear about how to balance community priorities with Indigenous research principles. We also discuss the strategies used to resolve each of these dilemmas. We draw examples from a project that examined the lived experiences of children and youth living with FASD and their caregivers. This project was conducted in collaboration with Sheshatshiu Innu First Nation, an Indigenous community in Labrador, Canada. In doing so, we argue that knowing the key guiding principles in Indigenous health research is not always enough, and that the 'real-world' context of practices and relationships can lead to conflicts that are not easily resolved with adherence to these principles.

2014-01-01

The aim of this study was to compare the measures of maximum bite force (MBF) in elderly edentulous indigenous (Mapuche) and non-indigenous individuals with new complete dentures at two different measuring times. A sample of 100 elderly subjects was divided into two groups: 50 indigenous and 50 non-indigenous, each including 25 females and 25 males. All individuals were totally edentulous, with new maxillary and mandibular removable complete dentures. Measurements were taken at the time of new prosthesis placement and after 1 month of use. Subjects were asked to perform with maximum effort three bites per side at maximum intercuspidation, with a rest time of 2 minutes in between. Statistics were analyzed with Student 's t-test. The MBF values were significantly higher in indigenous than non-indigenous subjects. Force after 1 month of wearing the new prosthesis was significantly higher than at the time of new prosthesis placement. No significant difference was found between sides. Elderly indigenous complete denture wearers had the greatest MBF values. Denture wearers were observed to undergo an adaptation process to the new prosthesis, with MBF increasing considerably after one month of use.

African Indigenous science in higher education in Uganda

NASA Astrophysics Data System (ADS)

Akena Adyanga, Francis

This study examines African Indigenous Science (AIS) in higher education in Uganda. To achieve this, I use anticolonial theory and Indigenous knowledge discursive frameworks to situate the subjugation of Indigenous science from the education system within a colonial historical context. These theories allow for a critical examination of the intersection of power relations rooted in the politics of knowledge production, validation, and dissemination, and how this process has become a systemic and complex method of subjugating one knowledge system over the other. I also employ qualitative and autoethnographic research methodologies. Using a qualitative research method, I interviewed 10 students and 10 professors from two universities in Uganda. My research was guided by the following key questions: What is African Indigenous Science? What methodology would help us to indigenize science education in Uganda? How can we work with Indigenous knowledge and anticolonial theoretical discursive frameworks to understand and challenge the dominance of Eurocentric knowledge in mainstream education? My research findings revealed that AIS can be defined in multiple ways, in other words, there is no universal definition of AIS. However, there were some common elements that my participants talked about such as: (a) knowledge by Indigenous communities developed over a long period of time through a trial and error approach to respond to the social, economic and political challenges of their society. The science practices are generational and synergistic with other disciplines such as history, spirituality, sociology, anthropology, geography, and trade among others, (b) a cumulative practice of the use, interactions with and of biotic and abiotic organism in everyday life for the continued existence of a community in its' totality. The research findings also indicate that Indigenous science is largely lacking from Uganda's education curriculum because of the influence of colonial and post-colonial education. Graduates of the colonial education system who are manning education in the country have themselves come to disdain Indigenous knowledge. The major findings from the study were: 1) participants' articulation of Indigenous science; 2) influence of organized religion on African Indigenous Science; 3) dominance of professors' foreign experiences in determining curriculum content; 4) protection of intellectual property rights for Indigenous science; and 5) collaborative research between Indigenous and Western scholars to enhance attitude change toward Indigenous science.

Indigenous people make up approximately 3% of the total Australian population and score poorer on all health indices, including back pain. Chiropractors are well placed to alleviate back pain, yet there is no research that considers chiropractors' readiness to treat Indigenous patients. This study explores chiropractors` experience working with Indigenous Australians, describes perceived barriers and facilitators to chiropractors' participation in Indigenous Healthcare and their willingness to engage in cultural competency training. This study used a non-representative cross-sectional design and a convenience sample. Participants were recruited via email invitation to complete an online survey and encouraged to send the invitation on to colleagues. A 17-item online-survey measured demographic data, perceived barriers and facilitators related to caring for Indigenous Australians, participants` level of comfort when working in Indigenous health, and their willingness to participate in cultural competency programs to enhance their skills, knowledge and cultural capacity when engaging with Indigenous Australians. Analysis of the data included descriptive statistics as well as thematic analysis of qualitative free text. One hundred and twenty-five chiropractors participated in the survey. The majority of participants (86%, n  = 108) were employed in private practice. 62% of respondents were members of the Chiropractors' Association of Australia, 41% were Chiropractic and Osteopathic College of Australasia members. 60% of chiropractors considered that they had, or do treat Indigenous patients yet only 4% of respondents asked their patients if they identified as Indigenous. A majority of participants expressed a high level of 'comfort' or confidence in working with Indigenous people while only 17% of respondents had undertaken some form of cultural proficiency training. A majority of respondents (62.7%, n  = 74) expressed an interest in working with Indigenous Australians and a majority (91%, n  = 104) were willing to participate in training to develop Indigenous cultural competency. The study points to a need for chiropractors to have access to cultural proficiency training in order to develop the capability and confidence to engage respectfully with their Indigenous patients. This preliminary study has provided the researchers with valuable insights aiding the development and implementation of an Indigenous cultural proficiency program for chiropractors.

Indigenous Australians experience profound levels of disadvantage in health, living standards, life expectancy, education and employment, particularly in comparison with non-Indigenous Australians. Very little information is available about the healthy development of Australian Indigenous children; the Longitudinal Study of Indigenous Children (LSIC) is designed to fill this knowledge gap.This dataset provides an opportunity to follow the development of up to 1759 Indigenous children. LSIC conducts annual face-to-face interviews with children (aged 0.5-2 and 3.5-5 years at baseline in 2008) and their caregivers. This represents between 5% and 10% of the total population of Indigenous children in these age groups, including families of varied socioeconomic and cultural backgrounds. Study topics include: the physical, social and emotional well-being of children and their caregivers; language; culture; parenting; and early childhood education.LSIC is a shared resource, formed in partnership with communities; its data are readily accessible through the Australian Government Department of Social Services (see http://dss.gov.au/lsic for data and access arrangements). As one of very few longitudinal studies of Indigenous children, and the only national one, LSIC will enable an understanding of Indigenous children from a wide range of environments and cultures. Findings from LSIC form part of a growing infrastructure from which to understand Indigenous child health. © The Author 2014.

During childhood and adolescence, eating habits become established which are instrumental in determining eating behavior later in life. Various authors have described the acculturation of the Mapuche people toward Western culture. The objective of this study was to analyze the eating characteristics of indigenous and non-indigenous adolescent girls in the Araucania Region of Chile. A cross-sectional design was used with a probabilistic sample of 281 adolescents comprised of 139 indigenous and 142 non-indigenous girls attending 168 elementary schools. A modified food frequency questionnaire was applied, designed to obtain information about eating habits and consumption of Mapuche foods. The eating schedules are similar in both ethnic groups, with dinner being the meal that is least consumed. Total snack consumption per week has a mean of 7 with an interquartile range (IQR) of 5 to 10 without any differences between ethnic groups; of these snacks, only 2 were healthy (IQR = 1 to 3). The indigenous girls had a higher probability of consumption of native foods including mote (boiled wheat) (OR = 2.00; IC = 0.93-4.29), muday (fermented cereal alcohol) (OR = 3.45; IC = 1.90-6.27), and yuyo (field mustard) (OR = 4.40; IC = 2.06-9.39). The study's conclusion is that the the eating habits and behavior of indigenous adolescents are similar to those of non-indigenous girls, though the former still consume more indigenous foods.

Health and indigenous people: intercultural health as a new paradigm toward the reduction of cultural and social marginalization?

PubMed

Torri, Maria Costanza

2010-01-01

The precarious socio-economic and health conditions of indigenous populations legitimize claims of marginalization and attest to the inherent inequality that indigenous groups suffer. In the last few years, advocates have urged the use of traditional indigenous health practices as more culturally fitting for most indigenous populations. An intercultural health program can reduce the conditions of social and cultural marginalization in an indigenous population. However, accepting and integrating indigenous medicine into a westernized health system presents a major challenge to intercultural healthcare in Latin America. The objective of this paper is to analyze the case of Makewe hospital, one of the first and few examples of intercultural health initiatives in Chile. The paper will examine the implementation of this initiative and the main challenges in creating an effective intercultural health program.

Numerical computation of space shuttle orbiter flow field

Tannehill, John C.

1988-01-01

A new parabolized Navier-Stokes (PNS) code has been developed to compute the hypersonic, viscous chemically reacting flow fields around 3-D bodies. The flow medium is assumed to be a multicomponent mixture of thermally perfect but calorically imperfect gases. The new PNS code solves the gas dynamic and species conservation equations in a coupled manner using a noniterative, implicit, approximately factored, finite difference algorithm. The space-marching method is made well-posed by special treatment of the streamwise pressure gradient term. The code has been used to compute hypersonic laminar flow of chemically reacting air over cones at angle of attack. The results of the computations are compared with the results of reacting boundary-layer computations and show excellent agreement.

Objective The Indigenous Burden of Disease (IBoD) report is the most comprehensive assessment of Indigenous disease burden in Australia. The aim of the present study was to investigate the potential effect of the IBoD report on Australian Indigenous health policy, service expenditure and research funding. Findings have significance for understanding factors that may influence Indigenous health policy. Methods The potential effect of the IBoD report was considered by: (1) conducting a text search of pertinent documents published by the federal government, Council of Australian Governments and the National Health and Medical Research Council of Australia (NHMRC) and observing the quantity and quality of references to IBoD; (2) examining data on government Indigenous healthcare expenditure for trends consistent with the findings and policy implications of the IBoD report; and (3) examining NHMRC Indigenous grant allocation trends consistent with the findings and policy implications of the IBoD report. Results Of 110 government and NHMRC documents found, IBoD was cited in 27. Immediately after publication of the IBoD report, federal and state governments increased Indigenous health spending (relative to non-Indigenous), notably for community health and public health at the state level. Expenditure on Indigenous hospital separations for chronic diseases also increased. These changes are broadly consistent with the findings of the IBoD report on the significance of chronic disease and the need to address certain risk factors. However, there is no evidence that such changes had a causal connection with the IBoD study. After publication of the IBoD report, changes in NHMRC Indigenous research funding showed little consistency with the findings of the IBoD report. Conclusions The present study found only indirect and inconsistent correlational evidence of the potential influence of the IBoD report on Indigenous health expenditure and research funding. Further assessment of the potential influence of the IBoD report on Indigenous health policy will require more targeted research, including interviews with key informants involved in developing health policy. What is known about the topic? There are currently no publications that consider the potential effed of the IBoD study on Indigenous health expenditure and research funding. What does this paper add? This paper offers the first consideration of the potential effect of the IBoD report. It contains analyses of data from readily available sources, examining national expenditures on Indigenous health and NHMRC Indigenous research, before and after the publication of the IBoD report. What are the implications for practitioners? The paper is relevant to analysts interested in drivers of Indigenous health policy. Although it finds correlations between the release of the IBoD report and some subsequent health spending decisions, other factors should be investigated to better understand the complexity of processes that drive government efforts to improve Indigenous health.

In this paper, a scheme called coded excitation with spectrum inversion (CEXSI) is presented. An established optimal binary code whose spectrum has no nulls and possesses the least variation is encoded as a burst for transmission. Using this optimal code, the decoding filter can be derived directly from its inverse spectrum. Various transmission techniques can be used to improve energy coupling within the system pass-band. We demonstrate its potential to achieve excellent decoding with very low (< 80 dB) side-lobes. For a 2.6 micros code, an array element with a center frequency of 10 MHz and fractional bandwidth of 38%, range side-lobes of about 40 dB have been achieved experimentally with little compromise in range resolution. The signal-to-noise ratio (SNR) improvement also has been characterized at about 14 dB. Along with simulations and experimental data, we present a formulation of the scheme, according to which CEXSI can be extended to improve SNR in sparse array imaging in general.

The NUGAM2 code predicts forward and backward angular energy differential and integrated distributions for gamma photons and fluorescent radiation emerging from finite laminar transport media. It determines buildup and albedo data for scientific research and engineering purposes; it also predicts the emission characteristics of finite radioisotope sources. The results are shown to be in very good agreement with available published data. The code predicts data for many situations in which no published data is available in the energy range up to 5 MeV. The NUGAM3 code predicts the pulse height response of inorganic (NaI and CsI) scintillation detectors to gamma photons. Because it allows the scintillator to be clad and mounted on a photomultiplier as in the experimental or industrial application, it is a more practical and thus useful code than others previously reported. Results are in excellent agreement with published Monte Carlo and experimental data in the energy range up to 4.5 MeV.

Indigenous alcohol and other drug (AOD) workers' roles are often exhausting, poorly paid and under-recognised. There has been relatively little examination of work-related stressors on their health and well-being. This national study identified Indigenous AOD workers' experiences and perspectives on well-being, stress and burnout along with strategies to improve worker well-being. Focus groups were conducted with 121 participants (70 Indigenous, 20 non-Indigenous, 31 unspecified) from metropolitan, rural and remote locations around Australia, selected via a purposive sampling strategy. Audio files and interview notes were analysed to identify key themes. Main themes identified included excessive workloads, extensive demands and expectations, workers' proximity to communities, loss and grief issues, lack of recognition, inadequate rewards, stigma and racism, and Indigenous ways of working. Stressors were compounded by workers' complex personal circumstances, profound levels of loss and grief, and lack of culturally safe working environments. Indigenous workers' stress was exacerbated by close links and responsibilities to their communities and a 'dual accountability', being constantly on call, playing multiple roles, complex personal and professional lives, and needing to interact with multiple agencies. Many Indigenous AOD workers had developed mechanisms to deal with work-related pressures and received valued support from their communities. The study identified the importance of workforce strategies to improve Indigenous workers' well-being and reduce stress, including: mutual support networks, training in assertiveness and boundary setting, workloads that take account of Indigenous ways of working, adequate remuneration, supervision and mentorship, and cultural sensitivity training for non-Indigenous workers. © 2013 Australasian Professional Society on Alcohol and other Drugs.

To estimate the prevalence of self-reported gingival and periodontal conditions and their association with smoking, oral hygiene, indigenous origin, diabetes and location (urban or rural) in indigenous and non-indigenous adults in Chiapas, Mexico. A cross-sectional study of 1,749 persons, ≥20 years of age, living in four rural and four urban marginal localities in Comitán (Chiapas, México). The variables investigated were: age; sex; indigenous origin; oral hygiene; halitosis; chewing ability; gingival conditions; periodontitis; smoking; alcoholism; diabetes; and location. Bivariate analysis and a logistic regression model were used to identify the association of periodontitis with the independent variables. In total, 762 (43.6%) indigenous and 987 (56.4%) non-indigenous persons were interviewed. Their mean age was 41 ± 14 years, 66.7% were women and 43.8% lived in rural locations. Gingival problems were reported by 68.5% and periodontitis by 8.7%. In total, 17.9% had used dental services during the previous year, 28.7% wore a removable partial or a complete dental prosthesis, 63.7% had lost at least one tooth, the prevalence of diabetes was 9.2% and the prevalence of smoking was 12.2%. The logistic regression model showed that age, diabetes and the interaction between rural location and indigenous origin were associated with the presence of periodontitis. Indigenous people living in rural areas are more likely to have periodontitis. It is necessary to promote oral health practices in indigenous and marginalised populations with a focus on community-oriented primary care. © 2016 FDI World Dental Federation.

Of the estimated 10-11 year life expectancy gap between Indigenous (Aboriginal and Torres Strait Islander people) and non-Indigenous Australians, approximately one quarter is attributable to cardiovascular disease (CVD). Risk prediction of CVD is imperfect, but particularly limited for Indigenous Australians. The BIRCH (Better Indigenous Risk stratification for Cardiac Health) project aims to identify and assess existing and novel markers of early disease and risk in Indigenous Australians to optimise health outcomes in this disadvantaged population. It further aims to determine whether these markers are relevant in non-Indigenous Australians. BIRCH is a cross-sectional and prospective cohort study of Indigenous and non-Indigenous Australian adults (≥ 18 years) living in remote, regional and urban locations. Participants will be assessed for CVD risk factors, left ventricular mass and strain via echocardiography, sleep disordered breathing and quality via home-based polysomnography or actigraphy respectively, and plasma lipidomic profiles via mass spectrometry. Outcome data will comprise CVD events and death over a period of five years. Results of BIRCH may increase understanding regarding the factors underlying the increased burden of CVD in Indigenous Australians in this setting. Further, it may identify novel markers of early disease and risk to inform the development of more accurate prediction equations. Better identification of at-risk individuals will promote more effective primary and secondary preventive initiatives to reduce Indigenous Australian health disadvantage.

To examine factors associated with hepatitis C virus (HCV) infection among a national sample of Indigenous and non-Indigenous people who inject drugs (PWID) in Australia. Respondents were recruited from Australia's Needle Syringe Program Survey; an annual bio-behavioural surveillance project that monitors HCV antibody prevalence among PWID. Data from 2006-2015 were de-duplicated to retain only one record where individuals participated in >1 survey round. Univariate and multivariable logistic regression examined demographic characteristics and injection-related behaviours associated with exposure to HCV. Among 17,413 respondents, 2,215 (13%) were Indigenous Australians. Compared to their non-Indigenous counterparts, Indigenous respondents were significantly more likely to be exposed to HCV infection (53% vs. 60% respectively, p<0.001). Among Indigenous respondents, HCV antibody positivity was independently associated with a history of imprisonment (Adjusted Odd Ratio [AOR] 2.13, 95%CI 1.73-2.64), opioid injection (AOR 1.53, 95%CI 11.43-2.16), recruitment in a metropolitan location (AOR 1.27, 95%CI 1.02-1.59), engagement in opioid substitution therapy (AOR 2.83, 95%CI 2.23-3.59) and length of time since first injection (p<0.001). Indigenous PWID are more likely to be exposed to HCV infection than their non-Indigenous counterparts. Implications for public health: Increased access to culturally sensitive harm reduction programs is required to prevent primary HCV infection and reinfection among Indigenous PWID. Given recent advances in HCV treatment, promotion of treatment uptake among Indigenous PWID may reduce future HCV-related morbidity and mortality. © 2017 The Authors.

Early onset of menarche has been linked to prevalence of obesity; however, this may differ for indigenous females. To analyse the relationship between age of menarche and nutritional status among indigenous and non-indigenous girls. The design of this study was cross-sectional. Date of menarche was determined through interviews, and all responses were confirmed by the girls' mothers. A total of 8504 adolescents were screened for recent menarche. One hundred and thirty-one girls of Mapuche (indigenous) and 143 girls of Chilean-Spanish background were identified and evaluated by anthropometric measurements. Median age of menarche was 150 months, interquartile range (IR) 143-157 in indigenous, and 145.5 months, IR 139-153 in non-indigenous girls (p = 0.04). The indigenous females showed a higher prevalence of overweight (36.4% vs 23.1%), although the frequency of obesity was similar (16.8% vs 16.3%). For indigenous girls, age of menarche was delayed by 2.69 months (confidence intervals (CI) -0.38 to 5.77). It was observed that girls with overweight experienced age of menarche 7.59 months earlier than those with normal weight, CI -10.78 to -4.41. In the analysis of obesity, the effect on age of menarche was similar, with onset 7.53 months earlier than for the normal weight, CI -11.34 to -3.72. Age of menarche is younger than has been previously reported and occurs earlier in girls with overweight and obesity, while being indigenous was not related.

1993-10-01

This interim report presents results of work completed in the ongoing verification and benchmark testing of the NUFT (Nonisothermal Unsaturated-saturated Flow and Transport) computer code. NUFT is a suite of multiphase, multicomponent models for numerical solution of thermal and isothermal flow and transport in porous media, with application to subsurface contaminant transport problems. The code simulates the coupled transport of heat, fluids, and chemical components, including volatile organic compounds. Grid systems may be cartesian or cylindrical, with one-, two-, or fully three-dimensional configurations possible. In this initial phase of testing, the NUFT code was used to solve seven one-dimensional unsaturated flow and heat transfer problems. Three verification and four benchmarking problems were solved. In the verification testing, excellent agreement was observed between NUFT results and the analytical or quasianalytical solutions. In the benchmark testing, results of code intercomparison were very satisfactory. From these testing results, it is concluded that the NUFT code is ready for application to field and laboratory problems similar to those addressed here. Multidimensional problems, including those dealing with chemical transport, will be addressed in a subsequent report.

A thermomechanical model for shape memory alloy (SMA) actuators and SMA hybrid composite (SMAHC) structures has been recently implemented in the commercial finite element codes MSC.Nastran and ABAQUS. The model may be easily implemented in any code that has the capability for analysis of laminated composite structures with temperature dependent material properties. The model is also relatively easy to use and requires input of only fundamental engineering properties. A brief description of the model is presented, followed by discussion of implementation and usage in the commercial codes. Results are presented from static and dynamic analysis of SMAHC beams of two types; a beam clamped at each end and a cantilevered beam. Nonlinear static (post-buckling) and random response analyses are demonstrated for the first specimen. Static deflection (shape) control is demonstrated for the cantilevered beam. Approaches for modeling SMAHC material systems with embedded SMA in ribbon and small round wire product forms are demonstrated and compared. The results from the commercial codes are compared to those from a research code as validation of the commercial implementations; excellent correlation is achieved in all cases.

Indigenous residents of Alaska's Bering Strait Region depend, both culturally and nutritionally, on ice seal and walrus harvests. Currently, climate change and resultant increases in marine industrial development threaten these species and the cultures that depend on them. To document: (a) local descriptions of the importance of marine mammal hunting; (b) traditional methods for determining if harvested marine mammals are safe to consume; and (c) marine mammal outcomes that would have adverse effects on community health, the perceived causes of these outcomes, strategies for preventing these outcomes and community adaptations to outcomes that cannot be mitigated. Semi-structured interviews and focus groups were conducted with 82 indigenous hunters and elders from the Bering Strait region. Standard qualitative analysis was conducted on interview transcripts, which were coded for both inductive and deductive codes. Responses describing marine mammal food safety and importance are presented using inductively generated categories. Responses describing negative marine mammal outcomes are presented in a vulnerability framework, which links human health outcomes to marine conditions. Project participants perceived that shipping noise and pollution, as well as marine mammal food source depletion by industrial fishing, posed the greatest threats to marine mammal hunting traditions. Proposed adaptations primarily fell into 2 categories: (a) greater tribal influence over marine policy; and (b) documentation of traditional knowledge for local use. This paper presents 1 example of documenting traditional knowledge as an adaptation strategy: traditional methods for determining if marine mammal food is safe to eat. Participant recommendations indicate that 1 strategy to promote rural Alaskan adaptation to climate change is to better incorporate local knowledge and values into decision-making processes. Participant interest in documenting traditional knowledge for local use also indicates that funding agencies could support climate change adaptation by awarding more grants for tribal research that advances local, rather than academic, use of traditional knowledge.

Interoperability and different ways of knowing: How semantics can aid in cross-cultural understanding

To address interoperability, we first need to understand how human perspectives and worldviews influence the way people conceive of and describe geophysical phenomena. There is never a single, unambiguous description of a phenomenon - the terminology used is based on the relationship people have with it and what their interests are. So how can these perspectives be reconciled in a way that is not only clear to different people but also formally described so that information systems can interoperate? In this paper we explore conceptions of Arctic sea ice as a means of exploring these issues. We examine multiple conceptions of sea ice and related processes as fundamental components of the Earth system. Arctic sea ice is undergoing rapid and dramatic decline. This will have huge impact on climate and biological systems as well as on shipping, exploration, human culture, and geopolitics. Local hunters, operational shipping forecasters, global climate researchers, and others have critical needs for sea ice data and information, but they conceive of, and describe sea ice phenomena in very different ways. Our hypothesis is that formally representing these diverse conceptions in a suite of formal ontologies can help facilitate sharing of information across communities and enhance overall Arctic data interoperability. We present initial work to model operational, research, and Indigenous (Iñupiat and Yup'ik) concepts of sea ice phenomena and data. Our results illustrate important and surprising differences in how these communities describe and represent sea ice, and we describe our approach to resolving incongruities and inconsistencies. We begin by exploring an intriguing information artifact, the World Meteorological Organization "egg code". The egg code is a compact, information rich way of illustrating detailed ice conditions that has been used broadly for a century. There is much agreement on construction and content encoding, but there are important regional differences in its application. Furthermore, it is an analog encoding scheme whose meaning has evolved over time. By semantically modeling the egg code, its subtle variations, and how it connects to other data, we illustrate a mechanism for translating across data formats and representations. But there are limits to what semantically modeling the egg-code can achieve. The egg-code and common operational sea ice formats do not address community needs, notably the timing and processes of sea ice freeze-up and break-up which have profound impact on local hunting, shipping, oil exploration, and safety. We work with local experts from four very different Indigenous communities and scientific creators of sea ice forecasts to establish an understanding of concepts and terminology related to fall freeze-up and spring break up from the individually represented regions. This helps expand our conceptions of sea ice while also aiding in understanding across cultures and communities, and in passing knowledge to younger generations. This is an early step to expanding concepts of interoperability to very different ways of knowing to make data truly relevant and locally useful.

Creating a path for indigenous student success in baccalaureate nursing education.

PubMed

Martin, Donna; Seguire, Marilyn

2013-04-01

To enhance recruitment and retention of indigenous peoples in nursing education, the University of Manitoba launched a cohort initiative in 2007. In this article, we describe the background, implementation, and evaluation of the initiative. Indigenous epistemology was integrated into the curriculum and pedagogy of prerequisite and beginning nursing courses. A cohort approach encourages peer support, which boosts individual and group strengths and academic success. Courses provide students with information about traditional indigenous knowledge, "Western" science, and how the history of colonialism continues to impact indigenous peoples in North America. Using the same instructors and advisors, in concert with tutoring, manageable course loads, and a culturally supportive environment, forges a path for success in indigenous students pursuing a baccalaureate nursing education. Key elements in the initiative may be adopted by nurse administrators and educators globally to inform the development of undergraduate nursing programs for indigenous peoples.

Crash and rebound of indigenous populations in lowland South America

NASA Astrophysics Data System (ADS)

Hamilton, Marcus J.; Walker, Robert S.; Kesler, Dylan C.

2014-04-01

Lowland South America has long been a battle-ground between European colonization and indigenous survival. Initial waves of European colonization brought disease epidemics, slavery, and violence that had catastrophic impacts on indigenous cultures. In this paper we focus on the demography of 238 surviving populations in Brazil. We use longitudinal censuses from all known indigenous Brazilian societies to quantify three demographic metrics: 1) effects of European contact on indigenous populations; 2) empirical estimates of minimum viable population sizes; and 3) estimates of post-contact population growth rates. We use this information to conduct population viability analysis (PVA). Our results show that all surviving populations suffered extensive mortality during, and shortly after, contact. However, most surviving populations exhibit positive growth rates within the first decade post-contact. Our findings paint a positive demographic outlook for these indigenous populations, though long-term survival remains subject to powerful externalities, including politics, economics, and the pervasive illegal exploitation of indigenous lands.

Learning by Observing and Pitching In and the Connections to Native and Indigenous Knowledge Systems.

PubMed

Urrieta, Luis

2015-01-01

This chapter opens a broader dialogue of Learning by Observing and Pitching-In (LOPI) with Native and Indigenous Studies, and Native and Indigenous Education, drawing particular attention to how LOPI can provide a model for better understanding Indigenous pedagogy in Indigenous Knowledge Systems (IKS). As Battiste (2002) pointed out, "Indigenous pedagogy values a person's ability to learn independently by observing, listening, participating with a minimum of intervention and instruction." Like LOPI, IKS include ways of knowing and ways of being in the world, with life-long processes and responsibilities that model competent and respectful behavior. The chapter explores similarities and differences between IKS and LOPI by analyzing each perspective's scope, defining features, and foundational origins, as well as what each contributes to our understanding of Native and Indigenous communities, especially in terms of learning and incorporation into adulthood and family and community life. © 2015 Elsevier Inc.

Much biodiversity lives on lands to which Indigenous people retain strong legal and management rights. However this is rarely quantified. Here we provide the first quantitative overview of the importance of Indigenous land for a critical and vulnerable part of biodiversity, threatened species, using the continent of Australia as a case study. We find that three quarters of Australia's 272 terrestrial or freshwater vertebrate species listed as threatened under national legislation have projected ranges that overlap Indigenous lands. On average this overlap represents 45% of the range of each threatened species while Indigenous land is 52% of the country. Hotspots where multiple threatened species ranges overlap occur predominantly in coastal Northern Australia. Our analysis quantifies the vast potential of Indigenous land in Australia for contributing to national level conservation goals, and identifies the main land management arrangements available to Indigenous people which may enable them to deliver those goals should they choose to do so.

Increasingly, automated methods are being used to code free-text medication data, but evidence on the validity of these methods is limited. To examine the accuracy of automated coding of previously keyed in free-text medication data compared with manual coding of original handwritten free-text responses (the 'gold standard'). A random sample of 500 participants (475 with and 25 without medication data in the free-text box) enrolled in the 45 and Up Study was selected. Manual coding involved medication experts keying in free-text responses and coding using Anatomical Therapeutic Chemical (ATC) codes (i.e. chemical substance 7-digit level; chemical subgroup 5-digit; pharmacological subgroup 4-digit; therapeutic subgroup 3-digit). Using keyed-in free-text responses entered by non-experts, the automated approach coded entries using the Australian Medicines Terminology database and assigned corresponding ATC codes. Based on manual coding, 1377 free-text entries were recorded and, of these, 1282 medications were coded to ATCs manually. The sensitivity of automated coding compared with manual coding was 79% (n = 1014) for entries coded at the exact ATC level, and 81.6% (n = 1046), 83.0% (n = 1064) and 83.8% (n = 1074) at the 5, 4 and 3-digit ATC levels, respectively. The sensitivity of automated coding for blank responses was 100% compared with manual coding. Sensitivity of automated coding was highest for prescription medications and lowest for vitamins and supplements, compared with the manual approach. Positive predictive values for automated coding were above 95% for 34 of the 38 individual prescription medications examined. Automated coding for free-text prescription medication data shows very high to excellent sensitivity and positive predictive values, indicating that automated methods can potentially be useful for large-scale, medication-related research.

High natural antibody titers of indigenous chickens are related with increased hazard in confinement

Natural antibody (NAb) levels and survival rates were evaluated in 4 breeds of laying hens in Ethiopia: indigenous, improved indigenous, exotic layer, and crossbred. Titers of NAb isotypes IgG and IgM binding keyhole limpet hemocyanin (KLH) in serum were measured at 20, 26, 35, and 45 wk age. Repeated-measure ANOVA showed that IgG and IgM levels vary with time within each breed (P < 0.05). Indigenous chickens had significantly (P < 0.05) higher NAb levels at all ages. The Cox proportional hazard analysis showed increased hazard with increased levels of NAbs in the exotic layers (P < 0.05). However, the reduced hazards with increased levels of NAbs were not significant in the improved indigenous and crossbred chickens. Indigenous chickens showed increased hazard with increasing levels of NAb (P > 0.05). We concluded that not only the NAb levels but also the effect of Nabs on survival vary between indigenous and improved breeds. The results indicate that NAb levels are associated with survival in elite (improved) breeds, but are associated with increased hazard in indigenous chickens. PMID:25910906

Reclaiming Indigenous identities: Culture as strength against suicide among Indigenous youth in Canada.

PubMed

Barker, Brittany; Goodman, Ashley; DeBeck, Kora

2017-06-16

In Canada, Indigenous youth suicide represents one of several health disparities burdening Indigenous populations, and like many other of these disparities, can be understood as an expression of societal, historical, cultural and familial trauma. As the number of Indigenous youth who take their own lives every year in Canada continues to far exceed national averages, it appears that conventional suicide prevention efforts remain ineffective among this population. A growing body of research argues that conventional interventions, largely rooted in Western individual-level behavioural change frameworks, are culturally discordant with Indigenous paradigms. In response, some Indigenous communities are turning to cultural revitalization as a holistic community-driven response to suicide prevention and treatment. The following commentary explores the emerging evidence base for "culture as treatment" - a novel approach to suicide that emphasizes the significance of interconnectedness in healing, alongside the revitalization of traditional values to reclaim community wellness. In doing so, we seek to contribute to a changing discourse surrounding Indigenous youth suicide by acknowledging culture as strength against this national crisis.

Health disparities exact a devastating toll upon Indigenous people in the USA. However, there has been scant research investment to develop strategies to address these inequities in Indigenous health. We present a case for increased health promotion, prevention, and treatment research with Indigenous populations, providing context to the recent NIH investment in the Intervention Research to Improve Native American Health (IRINAH) network. We discuss the disproportionate costs and consequences of disparities borne by Indigenous groups, the limited evidence base on effective intervention for this population, how population uniqueness often makes transfer of existing intervention models difficult, and additional challenges in creating interventions for Indigenous settings. Given the history of colonial disruption that has included genocide, forced removal from lands, damaging federal, state and local policies and practices, environmental contamination, and most recently, climate change, we conclude research that moves beyond minor transformations of existing majority population focused interventions, but instead truly respects Indigenous wisdom, knowledge, traditions, and aspirations is needed, and that investment in intervention science to address Indigenous health disparities represent a moral imperative.

There is an increased risk of physical health comorbidities in people with a mental illness. This paper examines the metabolic syndrome parameters for the general population, indigenous Australians and people with a mental illness, and compares them to a sample of predominantly indigenous adults with mental health problems. A longitudinal (24 month) audit of patient medical records was conducted between February 2011 and March 2013. The Kimberley Mental Health and Drug Service in Broome, Western Australia. Largely indigenous adults with a mental illness. Sample numbers increased from 56 at baseline (80% indigenous) to 136 at 18 months (70% indigenous). Waist circumference, blood pressure, fasting lipids, and fasting blood glucose. Preliminary assessment of the data indicates a high percentage of abnormalities at baseline and at the 18 month period on all four parameters, yet not all patients were assessed on a regular basis. Abnormalities in metabolic profiles consistent with the non-Indigenous mental health population were found. There are considerable challenges to implementing regular monitoring of physical and metabolic profiles of indigenous people in rural and remote communities. © 2015 National Rural Health Alliance Inc.

A Global Estimate of Seafood Consumption by Coastal Indigenous Peoples

Pauly, Daniel; Weatherdon, Lauren V.

2016-01-01

Coastal Indigenous peoples rely on ocean resources and are highly vulnerable to ecosystem and economic change. Their challenges have been observed and recognized at local and regional scales, yet there are no global-scale analyses to inform international policies. We compile available data for over 1,900 coastal Indigenous communities around the world representing 27 million people across 87 countries. Based on available data at local and regional levels, we estimate a total global yearly seafood consumption of 2.1 million (1.5 million–2.8 million) metric tonnes by coastal Indigenous peoples, equal to around 2% of global yearly commercial fisheries catch. Results reflect the crucial role of seafood for these communities; on average, consumption per capita is 15 times higher than non-Indigenous country populations. These findings contribute to an urgently needed sense of scale to coastal Indigenous issues, and will hopefully prompt increased recognition and directed research regarding the marine knowledge and resource needs of Indigenous peoples. Marine resources are crucial to the continued existence of coastal Indigenous peoples, and their needs must be explicitly incorporated into management policies. PMID:27918581

``Just Another Hoop to Jump Through?'' Using Environmental Laws and Processes to Protect Indigenous Rights

NASA Astrophysics Data System (ADS)

Middleton, Beth Rose

2013-11-01

Protection of culturally important indigenous landscapes has become an increasingly important component of environmental management processes, for both companies and individuals striving to comply with environmental regulations, and for indigenous groups seeking stronger laws to support site protection and cultural/human rights. Given that indigenous stewardship of culturally important sites, species, and practices continues to be threatened or prohibited on lands out of indigenous ownership, this paper examines whether or not indigenous people can meaningfully apply mainstream environmental management laws and processes to achieve protection of traditional sites and associated stewardship activities. While environmental laws can provide a “back door” to protect traditional sites and practices, they are not made for this purpose, and, as such, require specific amendments to become more useful for indigenous practitioners. Acknowledging thoughtful critiques of the cultural incommensurability of environmental law with indigenous environmental stewardship of sacred sites, I interrogate the ability of four specific environmental laws and processes—the Uniform Conservation Easement Act; the National Environmental Policy Act and the California Environmental Quality Act; the Pacific Stewardship Council land divestiture process; and Senate Bill 18 (CA-2004)—to protect culturally important landscapes and practices. I offer suggestions for improving these laws and processes to make them more applicable to indigenous stewardship of traditional landscapes.

From rustics to savants: indigenous materia medica in eighteenth-century Mexico.

PubMed

Achim, Miruna

2011-09-01

This essay explores how indigenous knowledge about plant and animal remedies was gathered, classified, tested, and circulated across wide networks of exchange for natural knowledge between Europe and the Americas. There has been much recent interest in the "bioprospecting" of local natural resources-medical and otherwise-by Europeans in the early modern world and the strategies employed by European travellers, missionaries, or naturalists have been well documented. By contrast, less is known about the role played by indigenous and Creole intermediaries in this process. And yet, the transmission of knowledge between indigenous communities and the European cabinet was neither transparent nor natural, and often involved epistemological, linguistic, and religious obstacles. Drawing on printed and manuscript collections of indigenous remedies, written in colonial Mexico between the sixteenth and the eighteenth centuries, I focus on how local intermediaries, like creoles scholars, sought to overcome such obstacles by observing indigenous uses of remedies, by studying indigenous languages and by producing natural histories and pharmacopoeias in indigenous languages. Ultimately, behind the Creole participation in the transmission of indigenous remedies, one can point to political and cultural interests and to inclusive definitions of knowledge, which cut across oppositions between science and superstition, cabinet and field, centre and periphery.

To synthesise client perceptions of the unique characteristics and value of care provided in Aboriginal Community Controlled Health Organisations (ACCHOs) compared to mainstream/general practitioner services, and implications for improving access to quality, appropriate primary health care for Indigenous Australians. Standardised systematic review methods with modification informed by ethical and methodological considerations in research involving Indigenous Australians. Perceived unique valued characteristics of ACCHOs were: 1) accessibility, facilitated by ACCHOs welcoming social spaces and additional services; 2) culturally safe care; and 3) appropriate care, responsive to holistic needs. Provider-client relationships characterised by shared understanding of clients' needs, Indigenous staff, and relationships between clients who share the same culture, are central to ACCHO clients' perceptions of ACCHOs' unique value. The client perceptions provide insights about how ACCHOs address socio-economic factors that contribute to high levels of chronic disease in Indigenous communities, why mainstream PHC provider care cannot substitute for ACCHO care, and how to improve accessibility and quality of care in mainstream providers. Implications for public health: To increase utilisation of PHC services in Indigenous Australian communities, and help close the gaps between the health status of Indigenous and non-Indigenous Australians, Indigenous community leaders and Australian governments should prioritise implementing effective initiatives to support quality health care provision by ACCHOs. © 2017 The Authors.

2017-01-01

Diabetes has reached epidemic proportions in Indigenous populations around the globe, and there is an urgent need to improve the health and health equity of Indigenous peoples with diabetes through timely and appropriate diabetes prevention and management strategies. This review describes the evolution of the diabetes epidemic in Indigenous populations and associated risk factors, highlighting gestational diabetes and intergenerational risk, lifestyle risk factors and social determinants as having particular importance and impact on Indigenous peoples. This review further describes the impact of chronic disease and diabetes on Indigenous peoples and communities, specifically diabetes-related comorbidities and complications. This review provides continued evidence that dramatic changes are necessary to reduce diabetes-related inequities in Indigenous populations, with a call to action to support programmatic primary healthcare transformation capable of empowering Indigenous peoples and communities and improving chronic disease prevention and management. Promising strategies for transforming health services and care for Indigenous peoples include quality improvement initiatives, facilitating diabetes and chronic disease registry and surveillance systems to identify care gaps, and prioritizing evaluation to build the evidence-base necessary to guide future health policy and planning locally and on a global scale.

Field-based education and indigenous knowledge: Essential components of geoscience education for native American communities

NASA Astrophysics Data System (ADS)

Riggs, Eric M.

2005-03-01

The purpose of this study is to propose a framework drawing on theoretical and empirical science education research that explains the common prominent field-based components of the handful of persistent and successful Earth science education programs designed for indigenous communities in North America. These programs are primarily designed for adult learners, either in a postsecondary or in a technical education setting and all include active collaboration between local indigenous communities and geoscientists from nearby universities. Successful Earth science curricula for indigenous learners share in common an explicit emphasis on outdoor education, a place and problem-based structure, and the explicit inclusion of traditional indigenous knowledge in the instruction. Programs sharing this basic design have proven successful and popular for a wide range of indigenous cultures across North America. We present an analysis of common field-based elements to yield insight into indigenous Earth science education. We provide an explanation for the success of this design based in research on field-based learning, Native American learning styles research, and theoretical and empirical research into the nature and structure of indigenous knowledge. We also provide future research directions that can test and further refine our understanding of best practices in indigenous Earth science education.

Fluid plasma models (and, in particular, the MHD model) are extensively used in the theoretical description of laboratory and astrophysical plasmas. We present here a successful benchmark between two nonlinear, three-dimensional, compressible visco-resistive MHD codes. One is the fully implicit, finite volume code PIXIE3D [1,2], which is characterized by many attractive features, notably the generalized curvilinear formulation (which makes the code applicable to different geometries) and the possibility to include in the computation the energy transport equation and the extended MHD version of Ohm's law. In addition, the parallel version of the code features excellent scalability properties. Results from this code, obtained in cylindrical geometry, are compared with those produced by the semi-implicit cylindrical code SpeCyl, which uses finite differences radially, and spectral formulation in the other coordinates [3]. Both single and multi-mode simulations are benchmarked, regarding both reversed field pinch (RFP) and ohmic tokamak magnetic configurations. [1] L.

MAPMAKER is one of the most widely used computer software package for constructing genetic linkage maps.However, the PC version, MAPMAKER 3.0 for PC, could not draw the genetic linkage maps that its Macintosh version, MAPMAKER 3.0 for Macintosh,was able to do. Especially in recent years, Macintosh computer is much less popular than PC. Most of the geneticists use PC to analyze their genetic linkage data. So a new computer software to draw the same genetic linkage maps on PC as the MAPMAKER for Macintosh to do on Macintosh has been crying for. Microsoft Excel,one component of Microsoft Office package, is one of the most popular software in laboratory data processing. Microsoft Visual Basic for Applications (VBA) is one of the most powerful functions of Microsoft Excel. Using this program language, we can take creative control of Excel, including genetic linkage map construction, automatic data processing and more. In this paper, a Microsoft Excel macro called MapDraw is constructed to draw genetic linkage maps on PC computer based on given genetic linkage data. Use this software,you can freely construct beautiful genetic linkage map in Excel and freely edit and copy it to Word or other application. This software is just an Excel format file. You can freely copy it from ftp://211.69.140.177 or ftp://brassica.hzau.edu.cn and the source code can be found in Excel's Visual Basic Editor.

Indigenous women in Canada have been hyper-visible in research, policy and intervention related to substance use during pregnancy; however, little is known about how the social determinants of health and substance use prior to, during, and after pregnancy intersect. The objectives of this study were to describe the social contexts of pregnant-involved young Indigenous women who use substances and to explore if an Indigenous-Specific Determinants of Health Model can predict substance use among this population. Using descriptive statistics and hierarchical logistic regression guided by mediation analysis, the social contexts of pregnant-involved young Indigenous women who use illicit drugs' lives were explored and the Integrated Life Course and Social Determinants Model of Aboriginal Health's ability to predict heavy versus light substance use in this group was tested (N = 291). Important distal determinants of substance use were identified including residential school histories, as well as protective factors, such as sex abuse reporting and empirical evidence for including Indigenous-specific determinants of health as important considerations in understanding young Indigenous women's experiences with pregnancy and substance use was provided. This analysis provided important insight into the social contexts of women who have experiences with pregnancy as well as drug and/or alcohol use and highlighted the need to include Indigenous-specific determinants of health when examining young Indigenous women's social, political and historical contexts in relation to their experiences with pregnancy and substance use.

The potential for health promotion through social networking sites (SNSs) is widely recognized. However, while health promotion prides itself in focusing on the social determinants of health, its partiality for persuading individuals to comply with health behaviours dominates the way health promotion utilizes SNSs. This paper contributes to an understanding of collaborative ways SNSs can work for health promotion agendas of self-determination and empowerment in an Indigenous Australia context. An ethnographic study was undertaken with Deadly Choices, an Indigenous-led health promotion initiative. The study involved participant observation of interactions on Deadly Choices SNSs between Deadly Choices and its online community members. Deadly Choices provides an example of SNSs providing a powerful tool to create a safe, inclusive and positive space for Indigenous people and communities to profile their healthy choices, according to Indigenous notions of health and identity. The study found five principles that underpin Deadly Choices' use of SNSs for health promotion. These are: create a dialogue; build community online and offline; incentivise healthy online engagement; celebrate Indigenous identity and culture; and prioritize partnerships. Deadly Choices SNSs empowers Indigenous people and communities to be health promoters themselves, which represents a power shift from health promotion practitioner to Indigenous people and communities and more broadly, an enactment of Indigenous self-determination on SNSs. Mainstream health promotion can learn from Indigenous health promotion practice regarding the use of SNSs for health promotion agendas. © The Author 2017. Published by Oxford University Press.

Contact investigations are a critical component of tuberculosis control in high-income countries. However, the relative success of conventional methods by population group and place of residence is unknown. This study compares outcomes of contact investigations of Canadian-born Indigenous tuberculosis cases living on- and off-reserve with other Canadian-born cases. In a retrospective analysis, Canadian-born adult culture-positive pulmonary TB cases (2001-2010) were identified. Characteristics of source cases and their contacts were compared by population group. Outcomes of contact investigations, including completion of recommended investigations and preventive therapy, were compared in multivariable analysis. Of 171 cases of tuberculosis identified, 49 (29%) were Indigenous on-reserve, 62 (36%) Indigenous off-reserve, and 60 (35%) non-Indigenous or Canadian-born, "other". Indigenous people had more contacts identified per case compared to non-Indigenous patients. Case population group and smear status were the main predictors of the success of contact investigations. Of those recommended preventive therapy, close contacts of Indigenous cases on-reserve had the highest rate of completion, at 54%, vs. 41% and 37% for close contacts of Indigenous living off-reserve and Canadian-born "other" respectively (p = 0.02). Contacts of Indigenous cases living off-reserve had the greatest delay in assessment and the lowest rates of completion of assessment and preventive therapy. In multivariable analysis, population group, smear status of source case and proximity of contact were predictors of preventive therapy acceptance and/or completion. Significant differences in outcomes of contact investigations were observed between population groups. The higher priority of contacts of smear-positive cases appears to influence efficiency of service delivery, regardless of population group. Jurisdictional differences in program delivery, resource availability and perceived risk of transmission likely influence outcomes of contact investigations.

The purpose of this study was to investigate the refractive status of the illiterate indigenous people of the upper Rio Negro region of the Amazon rain forest in northwestern Brazil. From an overall sample of 486 people, 259 indigenous people and 78 Brazilians between 12 and 59 years of age with no compromising optical opacities were refracted with cycloplegic retinoscopy. Subjects were categorized as indigenous if they had at least three generations of indigenous ancestry with no folklore suggesting other ancestors. Myopia was rare among the indigenous population. Only 2.7% of eyes showed myopia of -1.00 D or more and 1.6% (four people) had bilateral myopia of -1.00 D or more. Half of this small group were the only educated indigenous people examined. The prevalence of astigmatism and anisometropia equal to or >1.00 D was 15.5% and 8.2%, respectively. Most of the astigmatism in the indigenous people had an against-the-rule axis. Age was not associated with the refractive errors of the indigenous people. Brazilians from the small city in which the study was performed had higher rates of myopia (6.4% of eyes and 5.1% of subjects bilaterally). Older preeducation adults also had a very low prevalence of myopia (3.2% of eyes and 2.0% of subjects), whereas the younger, slightly educated Brazilians had a higher prevalence of myopia (11.3% of eyes and 9.7% of subjects). The low prevalence of myopia in the illiterate indigenous people is consistent with other studies and suggests that myopia is related to literacy. The generational change among the local mixed race Brazilians further supports this conclusion. The relatively high rates of astigmatism and anisometropia in the indigenous people were unusual for a predominantly emmetropic sample.

Indigenous women are subjected to high rates of multiple forms of violence, including intimate partner violence (IPV), in the context of ongoing colonization and neo-colonization. Health promotion interventions for women who experience violence have not been tailored specifically for Indigenous women. Reclaiming Our Spirits (ROS) is a health promotion intervention designed for Indigenous women living in an urban context in Canada. In this paper, we describe the development of the intervention, results of a pilot study, and the revised subsequent intervention. Building on a theory-based health promotion intervention (iHEAL) showing promising results in feasibility studies, ROS was developed using a series of related approaches including (a) guidance from Indigenous women with research expertise specific to IPV and Indigenous women's experiences; (b) articulation of an Indigenous lens, including using Cree (one of the largest Indigenous language groups in North America) concepts to identify key aspects; and (c) interviews with Elders (n = 10) living in the study setting. Offered over 6-8 months, ROS consists of a Circle, led by an Indigenous Elder, and 1:1 visits with a Registered Nurse, focused on six areas for health promotion derived from previous research. Pilot testing with Indigenous women (n = 21) produced signs of improvement in most measures of health from pre- to post-intervention. Women found the pilot intervention acceptable and helpful but also offered valuable suggestions for improvement. A revised intervention, with greater structure within the Circle and nurses with stronger knowledge of Indigenous women's experience and community health, is currently undergoing testing. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Indigenous Australians experience significantly worse graft and patient outcomes after kidney transplantation compared with nonindigenous Australians. It is unclear whether rural versus urban residential location might contribute to this. All adult patients from the Australia and New Zealand Dialysis and Transplant Registry who received a kidney transplant in Australia between January 1, 2000, and December 31, 2012, were investigated. Patients' residential location was classified as urban (major city + inner regional) or rural (outer regional - very remote) using the Australian Bureau of Statistics Remoteness Area Classification. Of 7826 kidney transplant recipients, 271 (3%) were indigenous. Sixty-three percent of indigenous Australians lived in rural locations compared with 10% of nonindigenous Australians (P < 0.001). In adjusted analyses, the hazards ratio for graft loss for Indigenous compared with non-Indigenous race was 1.59 (95% confidence interval [95% CI], 1.01-2.50; P = 0.046). Residential location was not associated with graft survival. Both indigenous race and residential location influenced patient survival, with an adjusted hazards ratio for death of 1.94 (95% CI, 1.23-3.05; P = 0.004) comparing indigenous with nonindigenous and 1.26 (95% CI, 1.01-1.58; P = 0.043) comparing rural with urban recipients. Five-year graft and patient survivals were 70% (95% CI, 60%-78%) and 69% (95% CI, 61%-76%) in rural indigenous recipients compared with 91% (95% CI, 90%-92%) and 92% (95% CI, 91%-93%) in urban nonindigenous recipients. Indigenous kidney transplant recipients experience worse patient and graft survival compared with nonindigenous recipients, whereas rural residential location is associated with patient but not graft survival. Of all groups, indigenous recipients residing in rural locations experienced the lowest 5-year graft and patient survivals.

Indigenous obesity in the news: a media analysis of news representation of obesity in Australia's Indigenous population.

High rates of obesity are a significant issue amongst Indigenous populations in many countries around the world. Media framing of issues can play a critical role in shaping public opinion and government policy. A broad range of media analyses have been conducted on various aspects of obesity, however media representation of Indigenous obesity remains unexplored. In this study we investigate how obesity in Australia's Indigenous population is represented in newsprint media coverage. Media articles published between 2007 and 2014 were analysed for the distribution and extent of coverage over time and across Indigenous and mainstream media sources using quantitative content analysis. Representation of the causes and solutions of Indigenous obesity and framing in text and image content was examined using qualitative framing analysis. Media coverage of Indigenous obesity was very limited with no clear trends in reporting over time or across sources. The single Indigenous media source was the second largest contributor to the media discourse of this issue. Structural causes/origins were most often cited and individual solutions were comparatively overrepresented. A range of frames were employed across the media sources. All images reinforced textual framing except for one article where the image depicted individual factors whereas the text referred to structural determinants. This study provides a starting point for an important area of research that needs further investigation. The findings highlight the importance of alternative news media outlets, such as The Koori Mail, and that these should be developed to enhance the quality and diversity of media coverage. Media organisations can actively contribute to improving Indigenous health through raising awareness, evidence-based balanced reporting, and development of closer ties with Indigenous health workers.

Augmented renal clearance (ARC) refers to the enhanced renal excretion of circulating solute commonly demonstrated in numerous critically ill subgroups. This study aimed to describe the prevalence of ARC in critically ill Indigenous Australian patients and explore the accuracy of commonly employed mathematical estimates of glomerular filtration. We completed a single-centre, prospective, observational study in the intensive care unit (ICU), Alice Springs Hospital, Central Australia. Participants were critically ill adult Indigenous and non-Indigenous Australian patients with a urinary catheter in situ. Exclusion criteria were anuria, pregnancy or the requirement for renal replacement therapy. Daily eight-hour measured creatinine clearances (CrCL_m) were collected throughout the ICU stay. ARC was defined by a CrCL_m ≥130 ml/min/1.73 m². The Cockcroft-Gault and Chronic Kidney Disease Epidemiology Collaboration equations were also used to calculate mathematical estimates for comparison. In total, 131 patients were recruited (97 Indigenous, 34 non-Indigenous) and 445 samples were collected. The median (range) CrCL_m was 93.0 (5.14 to 205.2) and 90.4 (18.7 to 206.8) ml/min/1.73 m² in Indigenous and non-Indigenous patients, respectively. Thirty-one of 97 (32%) Indigenous patients manifested ARC, compared to 7 of 34 (21%) non-Indigenous patients (P=0.21). Younger age, major surgery, higher baseline renal function and an absence of diabetes were all associated with ARC. Both mathematical estimates manifest limited accuracy. ARC was prevalent in critically ill Indigenous patients, which places them at significant risk of underdosing with renally excreted drugs. CrCL_m should be obtained wherever possible to ensure accurate dosing.

Indigenous health programs are seen as a curriculum response to addressing health disparities and social accountability. Several interrelated teaching approaches to cultural competency curricula have been recommended, however evidence of the impact of these on learner outcomes including engagement and self-reported competencies is limited. We aimed to explore undergraduate medical student perspectives of an indigenous health orientation program to inform curriculum strategies that promote learning and development of clinical skills. We analyzed quantitative and qualitative student evaluations (n = 602) of a three-day immersed indigenous health orientation program between 2006 and 2014 based on Likert-scale responses and open-text comments. We conducted a thematic analysis of narrative student experiences (n = 426). Overall, 509 of 551 respondents (92%) rated the indigenous health orientation program as extremely or highly valuable and most (87%) reported that the course strongly increased their interest in indigenous health. The features of the clinical course that enhanced value for learners included situated learning (learning environment; learning context); teaching qualities (enthusiasm and passion for Māori health; role-modelling); curriculum content (re-presenting Māori history; exploring Māori beliefs, values and practices; using a Māori health framework in clinical practice); teaching methodologies (multiple teaching methods; simulated patient interview); and building relationships with peers (getting to know the student cohort; developing professional working relationships). Undergraduate medical students valued an indigenous health program delivered in an authentic indigenous environment and that explicitly reframed historical notions of indigenous health to contextualize learning. Content relevant to clinical practice, faculty knowledge, and strengthened peer interactions combined to build learner confidence and self-reported indigenous health competencies. These findings suggest empirical evidence to support a curriculum approach to indigenous health teaching that enhances clinical learning.

Indigenous young people are currently highly overrepresented in the HIV epidemic in Canada, especially in the Prairie Provinces, such as Manitoba. Understanding HIV-vulnerability in Indigenous peoples must begin with understanding that social determinants are intersectional and linked to the historical legacy of European colonization. In this paper findings that detail the influence of the intersectional social determinants on Indigenous people who become infected with HIV in their youth are presented. The qualitative research design of phenomenology was used as it afforded the opportunity to understand Indigenous young people from their frames of reference and experiences of reality, resulting in a phenomenological understanding of their perspectives and experiences of the early years of living with HIV. A total of 21 Indigenous young people took part open-ended interviews. The stories that the Indigenous young people shared revealed their deeply interconnected social worlds, and how social determinants including abuse, trauma, being part of the child welfare system, and housing and food security were connected throughout various stages of their lives. Such stages included childhood, adolescence and young adulthood (the time of HIV infection), and later adulthood for older participants with the social determinants having multiple influences on their health trajectories. The findings highlight the need for policies and programs that are broadly focused, addressing multiple social determinants together. Overall, there needs to be more emphasis on the multiple social determinants in the life situations of all Indigenous youth. Reducing the health and social disparities in Indigenous youth is key to reducing the number of young Indigenous people diagnosed with HIV. The findings also shed light on the importance of listening to young Indigenous people who have experienced HIV diagnosis and life following diagnosis.

The perspectives of physicians caring for Indigenous patients with diabetes offer important insights into the provision of health-care services. The purpose of this study was to describe Canadian physicians' perspectives on diabetes care of Indigenous patients, a preliminary step in developing a continuing medical education intervention described elsewhere. Through in-depth semistructured interviews, Canadian family physicians and specialists with sizeable proportions of Indigenous clientele shared their experiences of working with Indigenous patients who have type 2 diabetes. Recruitment involved a purposive and convenience sampling strategy, identifying participants through existing research and the professional relationships of team members in the provinces of British Columbia, Alberta and Ontario. Participants addressed their understanding of factors contributing to the disease, approaches to care and recommendations for medical education. The research team framed a thematic analysis through a collaborative, decolonizing lens. The participants (n=28) included 3 Indigenous physicians, 21 non-Indigenous physicians and 4 non-Indigenous diabetes specialists. They practised in urban, reserve and rural adjacent-to-reserve contexts in 5 Canadian provinces. The physicians constructed a socially framed understanding of the complex contexts influencing Indigenous patients with diabetes in tension with structural barriers to providing diabetes care. As a result, physicians adapted care focusing on social factors and conditions that take into account the multigenerational impacts of colonization and the current social contexts of Indigenous peoples in Canada. Adaptations in diabetes care by physicians grounded in the historical, social and cultural contexts of their Indigenous patients offer opportunities for improving care quality, but policy and health system supports and structural competency are needed.

Stomach cancer is a leading cause of cancer death, especially in developing countries. Incidence has been associated with poverty and is also reported to disproportionately affect indigenous peoples, many of whom live in poor socioeconomic circumstances and experience lower standards of health. In this comprehensive assessment, we explore the burden of stomach cancer among indigenous peoples globally. The literature was searched systematically for studies on stomach cancer incidence, mortality and survival in indigenous populations, including Indigenous Australians, Maori in New Zealand, indigenous peoples from the circumpolar region, native Americans and Alaska natives in the USA, and the Mapuche peoples in Chile. Data from the New Zealand Health Information Service and the Surveillance Epidemiology and End Results (SEER) Program were used to estimate trends in incidence. Elevated rates of stomach cancer incidence and mortality were found in almost all indigenous peoples relative to corresponding non-indigenous populations in the same regions or countries. This was particularly evident among Inuit residing in the circumpolar region (standardised incidence ratios (SIR) males: 3.9, females: 3.6) and in Maori (SIR males: 2.2, females: 3.2). Increasing trends in incidence were found for some groups. We found a higher burden of stomach cancer in indigenous populations globally, and rising incidence in some indigenous groups, in stark contrast to the decreasing global trends. This is of major public health concern requiring close surveillance and further research of potential risk factors. Given evidence that improving nutrition and housing sanitation, and Helicobacter pylori eradication programmes could reduce stomach cancer rates, policies which address these initiatives could reduce inequalities in stomach cancer burden for indigenous peoples.

Infant mortality is higher in Indigenous than non-Indigenous populations, but comparable data on infant morbidity are lacking in Canada. We evaluated disparities in infant morbidities experienced by Indigenous populations in Canada. We used linked population-based birth and health administrative data from Quebec, Canada, to compare hospitalization rates, an indicator of severe morbidity, in First Nations, Inuit and non-Indigenous singleton infants (< 1 year) born between 1996 and 2010. Our cohort included 19 770 First Nations, 3930 Inuit and 225 380 non-Indigenous infants. Compared with non-Indigenous infants, all-cause hospitalization rates were higher in First Nations infants (unadjusted risk ratio [RR] 2.05, 95% confidence interval [CI] 1.99-2.11; fully adjusted RR 1.43, 95% CI 1.37-1.50) and in Inuit infants (unadjusted RR 1.96, 95% CI 1.87-2.05; fully adjusted RR 1.37, 95% CI 1.24-1.52). Higher risks of hospitalization (accounting for multiple comparisons) were observed for First Nations infants in 12 of 16 disease categories and for Inuit infants in 7 of 16 disease categories. Maternal characteristics (age, education, marital status, parity, rural residence and Northern residence) partly explained the risk elevations, but maternal chronic illnesses and gestational complications had negligible influence overall. Acute bronchiolitis (risk difference v. non-Indigenous infants, First Nations 37.0 per 1000, Inuit 39.6 per 1000) and pneumonia (risk difference v. non-Indigenous infants, First Nations 41.2 per 1000, Inuit 61.3 per 1000) were the 2 leading causes of excess hospitalizations in Indigenous infants. First Nations and Inuit infants had substantially elevated burdens of hospitalizations as a result of diseases of multiple systems. The findings identify substantial unmet needs in disease prevention and medical care for Indigenous infants. © 2017 Canadian Medical Association or its licensors.

A Global Assessment on Climate Research Engaging Indigenous Knowledge Systems and Recommendations for Quality Standards of Research Practice in Indigenous Communities

Indigenous communities worldwide have maintained their own knowledge systems for millennia informed through careful observation of dynamics of environmental changes. Withstanding centuries of challenges to their rights to maintain and practice these knowledge systems, Indigenous peoples continually speak to a need for quality standards for research in their communities. Although, international and Indigenous peoples' working groups emphasize Indigenous knowledge systems and the communities who hold them as critical resources for understanding and adapting to climate change, there has yet to be a comprehensive, evidence based analysis into how diverse knowledge systems are integrated in scientific studies. Do current research practices challenge or support Indigenous communities in their efforts to maintain and appropriately apply their knowledge systems? This study addresses this question using a systematic literature review and meta-analysis assessing levels of Indigenous community participation and decision-making in all stages of the research process (initiation, design, implementation, analysis, dissemination). Assessment is based on reported quality indicators such as: outputs that serve the community, ethical guidelines in practice (free, prior, and informed consent and intellectual property rights), and community access to findings. These indicators serve to identify patterns between levels of community participation and quality standards in practice. Meta-analysis indicates most climate studies practice an extractive model in which Indigenous knowledge systems are co-opted with minimal participation or decision-making authority from communities who hold them. Few studies report outputs that directly serve Indigenous communities, ethical guidelines in practice, or community access to findings. Studies reporting the most quality indicators were initiated in mutual agreement between Indigenous communities and outside researchers or by communities themselves. This study also draws from the researcher's experiences as an Indigenous scientist and includes recommendations for quality research practice. This global assessment provides an evidence base to inform our understanding of broader impacts related to research design.

To investigate time to follow-up (clinical investigation) for Indigenous and non-Indigenous women in Queensland after a high grade abnormality (HGA) being detected by Pap smear. Population-based retrospective cohort analysis of linked data from the Queensland Pap Smear Register (PSR), the Queensland Hospital Admitted Patient Data Collection, and the Queensland Cancer Registry. 34 980 women aged 20-68 years (including 1592 Indigenous women) with their first HGA Pap smear result recorded on the PSR (index smear) during 2000-2009 were included and followed to the end of 2010. Time from the index smear to clinical investigation (histology test or cancer diagnosis date), censored at 12 months. The proportion of women who had a clinical investigation within 2 months of a HGA finding was lower for Indigenous (34.1%; 95% CI, 31.8-36.4%) than for non-Indigenous women (46.5%; 95% CI, 46.0-47.0%; unadjusted incidence rate ratio [IRR], 0.65; 95% CI, 0.60-0.71). This difference remained after adjusting for place of residence, area-level disadvantage, and age group (adjusted IRR, 0.74; 95% CI, 0.68-0.81). However, Indigenous women who had not been followed up within 2 months were subsequently more likely to have a clinical investigation than non-Indigenous women (adjusted IRR for 2-4 month interval, 1.21; 95% CI, 1.08-1.36); by 6 months, a similar proportion of Indigenous (62.2%; 95% CI, 59.8-64.6%) and non-Indigenous women (62.8%; 95% CI, 62.2-63.3%) had been followed up. Prompt follow-up after a HGA Pap smear finding needs to improve for Indigenous women. Nevertheless, slow follow-up is a smaller contributor to their higher cervical cancer incidence and mortality than their lower participation in cervical screening.

Navajo Nation Community Health Representatives (CHR) are trained community health workers (CHWs) who provide crucial services for patients and families. The success of the CHRs' interventions depends on the interactions between the CHRs and their clients. This research investigates the culturally specific factors that build and sustain the CHR-client interaction. In-depth interviews were conducted with 16 CHRs on Navajo Nation. Interviews were transcribed and coded according to relevant themes. Code summaries were organized into a narrative using grounded theory techniques. The analysis revealed four findings critical to the development of a CHR-client relationship. Trust is essential to this relationship and provides a basis for providing quality services to the client. The ability to build and maintain trust is defined by tradition and culture. CHRs must be respectful of the diverse traditional and social practices. Lastly, the passing of clients brings together the CHR, the client's family, and the community. Understanding the cultural elements of the CHR-client relationship will inform the work of community partners, clinical providers, and other indigenous communities working to strengthen CHR programs and obtain positive health outcomes among marginalized communities.

Routinely collected linked administrative health, education and child protection data. Those in-scope for the study were women with a birth recorded on the Western Australian Midwives Notification System (1989-2007). Women who had an alcohol-related diagnosis (International Classification of Diseases Revisions 9/10) recorded on the Hospital Morbidity, Mental Health Inpatients and Outpatients, and Drug and Alcohol Office data sets formed the exposed group. The comparison cohort was frequency-matched to the exposed cohort based on maternal age within Indigenous status and child's year of birth. Child's school attendance was obtained from the Department of Education (2008-2012). Poor attendance was defined as <80% attendance for non-Indigenous children and <60% attendance for Indigenous children. 11 430 exposed children and 26 850 unexposed children had a linked attendance record. Maternal alcohol use disorder was significantly associated with increased odds of poor attendance (non-Indigenous: OR=1.61, 95% CI 1.50 to 1.74; Indigenous: OR=1.66, 95% CI 1.54 to 1.79). With adjustment for maternal and child factors, there was no significant difference between the timing of alcohol diagnosis relative to pregnancy and attendance outcomes. The population attributable fraction was higher in the Indigenous cohort than the non-Indigenous cohort (6.0% vs 1.3%). Maternal alcohol use disorder was associated with a significantly increased odds of poor school attendance for non-Indigenous and Indigenous children. There was no significant difference between the timing of diagnoses and odds of poor school attendance. This suggests that the effect of maternal alcohol use disorder may not be driven by the neurodevelopmental effects of alcohol exposure in utero, but may be mediated through family or social factors for which we were unable to adjust. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The burden of chronic disease in Indigenous Australia is more than double that of non-Indigenous populations and even higher in remote Northern Territory (NT) communities. Sufficient levels of physical activity are known to reduce the risk of chronic disease and improve the health of those already suffering from chronic disease. It has been identified that effective promotion of physical activity in Indigenous settings requires the diverse cultural perspectives and participation of Indigenous people. However, Indigenous concepts of physical activity are not represented in the public health literature and examples of Indigenous involvement in physical activity promotion are scarce. This study aimed to explore and describe local perspectives, experiences and meanings of physical activity in two remote NT Indigenous communities. Qualitative research methods guided by ethnographic and participatory action research principles were used. Semi-structured interviews conducted with 23 purposively selected community members were the main source of data, augmented by five commissioned paintings by community-based artists and observations recorded in a journal by the first author. The findings reveal that in this cultural context the meaning of physical activity is embedded in socially significant and economically necessary physical engagement with the environment. Participants described physical activities associated with Indigenous natural and cultural resource management, customary spaces, seasonal timing and traditional education as creating and protecting health. These activities were viewed not only as culturally appropriate physical activities that contribute to health but as legitimate, physically active forms of social organisation, education and employment that help to build and maintain relationships, wealth, resources and the environment. This different construction of physical activity in remote Indigenous communities highlights the importance of involving Indigenous people in the development and implementation of physical activity promotion. Physical activities associated with traditional Indigenous cultural practices and being active 'on country' need to be viewed as legitimate health promotion activities. Exploring further ways to enable Indigenous people in remote NT to be involved in creating viable active livelihoods on 'traditional country' needs to be considered as imperative to health improvement.

Studies have documented a higher disease burden in indigenous compared with nonindigenous populations, but no global data on the epidemiology of visual loss in indigenous peoples are available. A systematic review of literature on visual loss in the world's indigenous populations could identify major gaps and inform interventions to reduce their burden of visual loss. To conduct a systematic review on the prevalence and causes of visual loss among the world's indigenous populations. A search of databases and alternative sources identified literature on the prevalence and causes of visual loss (visual impairment and blindness) and eye diseases in indigenous populations. Studies from January 1, 1990, through August 1, 2017, that included clinical eye examinations of indigenous participants and, where possible, compared findings with those of nonindigenous populations were included. Methodologic quality of studies was evaluated to reveal gaps in the literature. Limited data were available worldwide. A total of 85 articles described 64 unique studies from 24 countries that examined 79 598 unique indigenous participants. Nineteen studies reported comparator data on 42 085 nonindigenous individuals. The prevalence of visual loss was reported in 13 countries, with visual impairment ranging from 0.6% in indigenous Australian children to 48.5% in native Tibetans 50 years or older. Uncorrected refractive error was the main cause of visual impairment (21.0%-65.1%) in 5 of 6 studies that measured presenting visual acuity. Cataract was the main cause of visual impairment in all 6 studies measuring best-corrected acuity (25.4%-72.2%). Cataract was the leading cause of blindness in 13 studies (32.0%-79.2%), followed by uncorrected refractive error in 2 studies (33.0% and 35.8%). Most countries with indigenous peoples do not have data on the burden of visual loss in these populations. Although existing studies vary in methodologic quality and reliability, they suggest that most visual loss in indigenous populations is avoidable. Improvements in quality and frequency of research into the eye health of indigenous communities appear to be required, and coordinated eye care programs should be implemented to specifically target the indigenous peoples of the world.

This paper contributes to the development of theoretical and methodological approaches that aim to engage indigenous, technical and academic knowledge for environmental management. We present an exploratory analysis of a transdisciplinary project carried out to identify and contrast indigenous and academic perspectives on the relationship between the Africanized honey bee and stingless bee species in the Brazilian Amazon. The project was developed by practitioners and researchers of the Instituto Socioambiental (ISA, a Brazilian NGO), responding to a concern raised by a funding agency, regarding the potential impact of apiculture development by indigenous peoples, on the diversity of stingless bee species in the Xingu Park, southern Brazilian Amazon. Research and educational activities were carried out among four indigenous peoples: Kawaiwete or Kaiabi, Yudja or Juruna, Kīsêdjê or Suyá and Ikpeng or Txicão. A constructivist qualitative approach was developed, which included academic literature review, conduction of semi-structured interviews with elders and leaders, community focus groups, field walks and workshops in schools in four villages. Semi-structured interviews and on-line surveys were carried out among academic experts and practitioners. We found that in both indigenous and scientific perspectives, diversity is a key aspect in keeping exotic and native species in balance and thus avoiding heightened competition and extinction. The Africanized honey bee was compared to the non-indigenous westerners who colonized the Americas, with whom indigenous peoples had to learn to coexist. We identify challenges and opportunities for engagement of indigenous and scientific knowledge for research and management of bee species in the Amazon. A combination of small-scale apiculture and meliponiculture is viewed as an approach that might help to maintain biological and cultural diversity in Amazonian landscapes. The articulation of knowledge from non-indigenous practitioners and researchers with that of indigenous peoples might inform sustainable management practices that are, at the same time, respectful of indigenous perspectives and intellectual property rights. However, there are ontological, epistemological, political and financial barriers and constraints that need to be addressed in transdisciplinary research projects inter-relating academic, technical and indigenous knowledge systems for environmental management.
