Genetic Variation and Population Structure in Native Americans

We examined genetic diversity and population structure in the American landmass using 678 autosomal microsatellite markers genotyped in 422 individuals representing 24 Native American populations sampled from North, Central, and South America. These data were analyzed jointly with similar data available in 54 other indigenous populations worldwide, including an additional five Native American groups. The Native American populations have lower genetic diversity and greater differentiation than populations from other continental regions. We observe gradients both of decreasing genetic diversity as a function of geographic distance from the Bering Strait and of decreasing genetic similarity to Siberians-signals of the southward dispersal of human populations from the northwestern tip of the Americas. We also observe evidence of: (1) a higher level of diversity and lower level of population structure in western South America compared to eastern South America, (2) a relative lack of differentiation between Mesoamerican and Andean populations, (3) a scenario in which coastal routes were easier for migrating peoples to traverse in comparison with inland routes, and (4) a partial agreement on a local scale between genetic similarity and the linguistic classification of populations. These findings offer new insights into the process of population dispersal and differentiation during the peopling of the Americas.

Through the back door : Melungeon literacies and 21st century technologies

The Melungeons, a minority recognized in Southern Appalachia where they settled in the early 1800s, have mixed heritage—European, Mediterranean, Native American, and Sub-Saharan African. Their dark skin and distinctive features have marked them and been the cause of racial persecution both by custom and by law in Appalachia for two centuries. Their marginalization has led to an insider mentality, which I call a “literacy” of Melungeon-ness that affects every facet of their lives. Just a century ago, while specialized practices such as farming, preserving food, hunting, gathering, and distilling insured survival in the unforgiving mountain environment, few Melungeons could read or write. Required to pay property taxes and render military service, they were denied education, suffrage, and other legal rights. In the late 1890s visionary Melungeon leader Batey Collins invited Presbyterian homemissionaries to settle in one Tennessee Melungeon community where they established a church and built a school of unparalleled excellence. Educator-ministers Mary Rankin and Chester Leonard creatively reified the theories of Dewey, Montessori, and Rauschenbusch, but, despite their efforts, school literacy did not neutralize difference. Now, taking reading and writing for granted, Melungeons are exploring their identity by creating websites and participating in listserv discussions. These online expressions, which provide texts for rhetorical, semiotic, and socio-linguistic analysis, illustrate not solidarity but fragmentation on issues of origins and legitimacy. Armed with literacies of difference stemming from both nature and nurture, Melungeons are using literacy practices to embrace the difference they cannot escape.

Characteristics of a spina bifida population including North American Caucasian and Hispanic individuals.

BACKGROUND: Meningomyelocele (MM) is a common human birth defect. MM is a disorder of neural development caused by contributions from genes and environmental factors that result in the NTD and lead to a spectrum of physical and neurocognitive phenotypes. METHODS: A multidisciplinary approach has been taken to develop a comprehensive understanding of MM through collaborative efforts from investigators specializing in genetics, development, brain imaging, and neurocognitive outcome. Patients have been recruited from five different sites: Houston and the Texas-Mexico border area; Toronto, Canada; Los Angeles, California; and Lexington, Kentucky. Genetic risk factors for MM have been assessed by genotyping and association testing using the transmission disequilibrium test. RESULTS: A total of 509 affected child/parent trios and 309 affected child/parent duos have been enrolled to date for genetic association studies. Subsets of the patients have also been enrolled for studies assessing development, brain imaging, and neurocognitive outcomes. The study recruited two major ethnic groups, with 45.9% Hispanics of Mexican descent and 36.2% North American Caucasians of European descent. The remaining patients are African-American, South and Central American, Native American, and Asian. Studies of this group of patients have already discovered distinct corpus callosum morphology and neurocognitive deficits that associate with MM. We have identified maternal MTHFR 667T allele as a risk factor for MM. In addition, we also found that several genes for glucose transport and metabolism are potential risk factors for MM. CONCLUSIONS: The enrolled patient population provides a valuable resource for elucidating the disease characteristics and mechanisms for MM development.

Factors Related to Mental Health of Native Americans in Eastern Tribes

This paper is part of a five-year research project funded by the National Institute on Disability and Rehabilitation Research (NIDRR) that addresses the health, disability and service needs of Native Americans in eastern tribes. The Participatory Action Research model with a community-based approach was used to facilitate collaboration among the participating tribes. Native American research technicians conducted individual interviews with members of their tribes. Demographics, prevalence of disabilities, and various factors associated with health and mental health are presented. Of the 858 tribal members who responded to survey questions, the third most prominent health problem reported was mental illness.

European mink (Mustela lutreola) and American mink (Neovison vison) detection histories in Northern Spain between 2000 and 2011

Understanding changes over time in the distribution of interacting native and invasive species that may be symptomatic of competitive exclusion is critical to identify the need for and effectiveness of management interventions. Occupancy models greatly increase the robustness of inference that can be made from presence/absence data when species are imperfectly detected, and recent novel developments allow for the quantification of the strength of interaction between pairs of species. We used a two-species multi-season occupancy model to quantify the impact of the invasive American mink on the native European mink in Spain through the analysis of their co-occurrence pattern over twelve years (2000 - 2011) in the entire Spanish range of European mink distribution, where both species were detected by live trapping but American mink were culled. We detected a negative temporal trend in the rate of occupancy of European mink and a simultaneous positive trend in the occupancy of American mink. The species co-occurred less often than expected and the native mink was more likely to become extinct from sites occupied by the invasive species. Removal of American mink resulted in a high probability of local extinction where it co-occurred with the endemic mink, but the overall increase in the probability of occupancy over the last decade indicates that the ongoing management is failing to halt its spread. More intensive culling effort where both species co-exist as well as in adjacent areas where the invasive American mink is found at high densities is required in order to stop thedecline of European mink.

Effects of invasive Africanized honey bees (Apis mellifera scutellata) on native stingless bee populations (Meliponinae) and traditional Mayan beekeeping in central Quintana Roo, Mexico

The Maya of the Yucatan region have a long history of keeping the native stingless bees (subfamily Meliponinae). However, market forces in the last few decades have driven the Maya to favor the use of invasive Africanized honey bees (Apis mellifera scutellata) for producing large quantities of high quality honey that has an international market. Furthermore, the native bees traditionally used by the Maya are now disappearing, along with the practice of keeping them. ^ An interdisciplinary approach was taken in order to determine the social factors behind the decrease in stingless beekeeping and the ecological driving forces behind their disappearance from the wild. Social research methods included participant observation with stingless beekeepers, Apis beekeepers, and marketing intermediaries. Ecological research methods included point observations of commonly known melliferous and polliniferous plants along transects in three communities with different degrees of human induced ecosystem disturbance. ^ The stingless bee species most important to the Maya, Melipona beecheii, has become extremely rare, and this has caused a breakdown of stingless beekeeping tradition, compounded with the pressure of the market economy, which fuels Apis beekeeping and has lessened the influence of traditional practices. The community with the heaviest amount of human induced ecosystem disturbance also had the highest degree of dominance of Apis mellifera, while the area with the most intact ecosystem had the highest diversity of stingless bees, though Apis mellifera was still the dominant species. Aggressive competitive behavior involving physical attacks by Apis mellifera against stingless bees was observed on several occasions, and this is a new observation previously unreported by science. ^

Health a focus at international conference

The 2009 Native American and Indigenous Studies Conference recently held in Minneapolis, Minnesota, United States of America attracted over 600 scholars. The Conference was scholarly and interdisciplinary and was intended for Indigenous and non-Indigenous scholars who work in American Indian/ Native American/ First Nations/ Aboriginal/ Indigenous Studies. Scholars came from USA, Canada, Hawaii, Central and South America, New Zealand, Switzerland, England and Australia. The aim of the Native American and Indigenous Studies Conference is to offer a chance to scholars working in the field of Indigenous Studies to present scholarly work. The 2009 witnessed a selection of papers from the discipline of Health. This article gives an overview of the Conference and some of the health papers.

Being and Living in an Australian Urban Community

There is a limited evidence base which highlights the plight of Australian Aboriginal and Torres Strait Islander populations living in urban areas and the issues that impact on Indigenous achievements in education, health status, housing needs, rates of incarceration and the struggle for cultural recognition. This is despite over 70 % of all Aboriginal and Torres Strait Islander people in Australia now living in urban or regional urban areas (ABS 2008). The statistics demonstrate that living in urban centres is as much part of reality for Australian Aboriginal and Torres Strait Islander people as living in a remote discrete community. Using the capital city of Brisbane, Queensland as a case study, this paper will explore some of the issues that Aboriginal and Torres Strait Islander peoples face against a backdrop of the statistics and some of the current literature. It will additionally explore why there has been limited research with Aboriginal and Torres Strait Islander populations in urban areas and highlight some of the innovative research taking place which will begin to redress this gap. The research issues presented within this paper will resonate with some of the Native American and Indigenous movement patterns and associated issues additionally occurring in the United States of America, Canada and New Zealand.

How Australia’s Indigenous people are positioned within health service sites by our presence and by our absence

De Certeau (1984) constructs the notion of belonging as a sentiment which develops over time through the everyday activities. He explains that simple everyday activities are part of the process of appropriation and territorialisation and suggests that over time belonging and attachment are established and built on memory, knowledge and the experiences of everyday activities. Based on the work of de Certeau, non-Indigenous Australians have developed attachment and belonging to places based on the dispossession of Aboriginal people and on their everyday practices over the past two hundred years. During this time non-Indigenous people have marked their appropriation and territorialisation with signs, symbols, representations and images. In marking their attachment, they also define how they position Australia’s Indigenous people by both our presence and our absence. This paper will explore signs and symbols within spaces and places in health services and showcase how they reflect the historical, political, cultural, social and economic values, and power relations of broader society. It will draw on the voices of Aboriginal women to demonstrate their everyday experiences of such sites. It will conclude by highlighting how Aboriginal people assert their identities and un-ceded sovereignty within such health sites and actively resist on-going white epistemological notions of us and the logic of patriarchal white sovereignty.

The Aboriginal version of Ken Done ... banal aboriginal identities in Australia

Histories of representation of Blackness are quite distinct in Australia and in America. Indigenous Australian identities have been consistently 'fatal', in Baudrillard's use of that term. So, while Black American representation includes intensely banal images of middle-class, materialistic individuals, such histories are largely absent in the Australian context. This implies that the few such representations which do occur — and particularly those of everyday game shows such as Sale of the Century and Family Feud — are particularly important for presenting a trivial, unexciting version of Aboriginality. This also clarifies the distinction between American and Australian versions of Blackness, and suggests that the latter set of representations might be more usefully viewed in relation to Native American rather than Black American images. The status of indigeneity might prove to be more relevant to Australian Aboriginal representation than the previously favoured identity of skin colour (Blackness).

Living with the Legacy of Conquest and Culture : Social Justice Leadership in Education and the Indigenous Peoples of Australia and America

Indigenous peoples have survived the most inhumane acts and violations against them. Despite acts of genocide, Aboriginal Australians and Native Americans have survived. The impact of the past 500 years cannot be separated from understandings of education for Native Americans in the same way that the impact of the past 220 years cannot be separated from the understandings of Australian Aboriginal people’s experiences of education. This chapter is about comparisons in Aboriginal and Native American communities and their collision with the dominant, white European settlers who came to Australia and America. Chomsky (Intervention in Vietnam and Central America: parallels and differences. In: Peck J (ed) The Chomsky Reader. Pantheon Books, New York, p 315, 1987) once remarked that if one took two historical events and compared them for similarities and differences, you would find both. The real test was whether on the similarities they were significant. The position of the coauthors of this chapter is in the affirmative and we take this occasion to lay them out for analysis and review. The chapter begins with a discussion of the historical legacy of oppression and colonization impacting upon Indigenous peoples in Australia and in the United States, followed by a discussion of the plight of Indigenous children in a specific State in America. Through the lens of social justice, we examine those issues and attitudes that continue to subjugate these same peoples in the economic and educational systems of both nations. The final part of the chapter identifies some implications for school leadership.

Understanding the mental health of refugees: Trauma, stress, and the cultural context

Long considered important for professionals working with minority and under-represented populations, cross-cultural competency has become a requisite for all health care providers. As society in the US increasingly diversifies, there is a crucial need to prepare health care professionals to effectively treat this changing population. The Massachusetts General Hospital Textbook on Diversity and Cultural Sensitivity in Mental Health addresses the importance and relevance of cultural sensitivity in US mental health. Prominent researchers and clinicians examine the cultural and cross-cultural mental health issues of Native American, Latino, Asian, African American, Middle Eastern, Refugee and LGBQT communities. The discussion includes understanding the complexities in making mental health diagnoses and the various meanings it has for the socio-cultural group described, as well as biopsychosocial treatment options and challenges. In understanding the specific populations, the analysis delves into overarching concepts that may apply to specific populations and to those at the intersection of multiple cultures. An invaluable resource for mental health professionals, including clinicians, researchers, educators, leaders and advocates in the United States, The Massachusetts General Hospital Textbook on Diversity and Cultural Sensitivity in Mental Health provides the necessary understanding and insights for research and clinical practice in specific cultural and multicultural groups.
