Rexistência Nas Fronteiras Do Capitalismo/Colonialismo: A Ecologia Política Do Isolamento E Da Soberania, Felipe Milanez Dec 2019

Rexistência Nas Fronteiras Do Capitalismo/Colonialismo: A Ecologia Política Do Isolamento E Da Soberania, Felipe Milanez

Tipití: Journal of the Society for the Anthropology of Lowland South America

Ofereço a perspectiva da ecologia política para rever e atualizar a política de “isolamento” e “não-contato” com base nos conceitos de soberania e necropolítica, sugerindo uma nova proposta de prática política para situações de conflitos em territórios ocupados por povos indígenas que resistem à conquista pela guerra e distanciamento. Da perspectiva do estudo dos conflitos ambientais, a ecologia política questiona a noção de isolamento ao inseri-la como parte do sistema mundo capitalista/colonial. Diante do quadro crescente de fascistização social e violência do Estado, cuja pressão sobre os territórios tornou-se ainda mais intenso, é a morte e a vida destes coletivos …


Tubes And Androgyny: Comment On "Thinking Through Tubes", Françoise Barbira Freedman Dec 2019

Tubes And Androgyny: Comment On "Thinking Through Tubes", Françoise Barbira Freedman

Tipití: Journal of the Society for the Anthropology of Lowland South America

In this comment on Stephen Hugh-Jones’s "Thinking Through Tubes" Françoise Barbira Freedman offers a feminist meditation on the semiotics of androgyny in Northwest Amazonian shamanism, ritual life and mythology. By focusing on processes of detotalization and retotalization that move beings from an androgynous state to a single-sex identity and back again, Barbira Freedman reveals a dynamic "one sex, two genders model of androgyny" that could not be further from a concept of androgyny as blurred gender. These movements in and out of a one sex state are largely the preserve of men so that androgynous features of the cosmos are …


A Story Of Two Videos Plus Coda: Perspectives On "Contact" In Western Amazonia, Giancarlo Rolando Dec 2019

A Story Of Two Videos Plus Coda: Perspectives On "Contact" In Western Amazonia, Giancarlo Rolando

Tipití: Journal of the Society for the Anthropology of Lowland South America

In 2014, the Xinane people of Brazilian Amazonia made international news after two videos showing scenes of their “first contact” were uploaded to the internet. This paper explores the ways in which different audiences reacted to news about this “first contact.” Local Peruvian and Brazilian settlers, the international public, and the Mastanawa, a people culturally proximate to the Xinane, had different readings of this event and expressed opposing views concerning what actions should have been taken following the events depicted in the videos. These differences in opinion are telling of the different ways in which each group thinks of “isolated …

Singularity On The Margins: Autobiographical Writings Among The Shuar Of Ecuadorian Amazonia, Grégory Deshoulliere, Natalia Buitron Dec 2019

Singularity On The Margins: Autobiographical Writings Among The Shuar Of Ecuadorian Amazonia, Grégory Deshoulliere, Natalia Buitron

Tipití: Journal of the Society for the Anthropology of Lowland South America

Inspired by Stephen Hugh-Jones’s suggestion of a fit between Tukanoan writing genres and their sociocultural systems, in this article we explore Shuar autobiographical writings in light of Chicham (Jivaroan) individualism. By exploring first-person—nonpatrimonial—texts that have received much less attention in the regional literature, the article contributes to theorizing a different way of transmitting tradition:one focused on individual praxis rather than on collective patrimony. Through the analysis of three autobiographical texts, we show how their authors appropriate writing to construct singularity, or distinct “paths of individuation”: the personal story of resistance of a school teacher, the exemplary life course of a …


La Política Pública De No Contacto De Los Pueblos Indígenas En Aislamiento Y Contacto Inicial, Carlos Antonio Martin Soria Dall'orso Dec 2019

Luego se propone cual es la situación territorial de los PIACI en varios países amazónicos, para entender que estos pueblos habitan paisajes complejos de derechos otorgados a ellos pero, a veces también al Estado y a terceros. A continuación se reflexiona sobre la propuesta de reconocer Corredores de Protección PIACI como una propuesta que permite integrar varias áreas de protección PIACI que son colindantes para así a …


A Brief Comment On Hugh-Jones's "The Origin Of Night And The Dance Of Time", Geraldo Andrello Dec 2019

A Brief Comment On Hugh-Jones's "The Origin Of Night And The Dance Of Time", Geraldo Andrello

Tipití: Journal of the Society for the Anthropology of Lowland South America

In this comment on Hugh-Jones’s article "The Origin of Night," Geraldo Andrello argues that the politics of myth narrations and ritual performances are enacted through the regulation of temporality and explains why it is that all-important status distinctions are brought into existence through the retelling of permutations of the Origin of Night myth.


Maloca-Escola: Transformations Of The Tukanoan House, Melissa S. Oliveira Dec 2019

Maloca-Escola: Transformations Of The Tukanoan House, Melissa S. Oliveira

Tipití: Journal of the Society for the Anthropology of Lowland South America

This paper aims to demonstrate how, by combining the foundation of an indigenous school with the construction of a longhouse (maloca), the Tukano indigenous association of the Hausirõ and Ñahuri Porã clans, Middle Tiquié river, produces social relations proper to Tukanoan House societies as described by Hugh-Jones (1991, 1993). Through "indigenous research" and the celebrations that mark the school calendar, internal subdivisions of clan, hierarchy, age and gender are marked in space, while, at the same time, this new space allows for interdependence and articulation with other indigenous groups and outsiders (especially NGO professionals, scientists and politicians). In …

Tipití: Journal of the Society for the Anthropology of Lowland South America

Este artigo discute a territorialidade dos Yine Manxinerune Hosha Hajene (os Mashco Piro), um grupo em isolamento voluntário, estabelecida na Terra Indígena Mamoadate, estado do Acre/Brasil, a partir da governança dos Manxineru. As práticas de diferentes atores, como governo, organizações não-governamentais, corporações e comunidades indígenas são considerados em conjunto para situar e discutir a mobilização dos Manxineru na criação de um novo espaço para os Yine Manxinerune Hosha Hajene. Propomos que as escolhas políticas dos Manxineru, em relação à presença dos Yine Manxinerune Hosha Hajene, são baseadas fundamentalmente na sua memória do contato com não-indígenas.

Miradas Del Aislamiento Y Del Contacto: Una Crónica Sobre Los Llamados Mashco Piro, Luis Felipe Torres Espinoza

Tipití: Journal of the Society for the Anthropology of Lowland South America

Este artículo presenta una breve crónica sobre la historia y el presente del pueblo indígena denominado mashco piro, considerado en situación de “aislamiento” por los gobiernos de Perú y Brasil. Además de considerar las amenazas externas que existen sobre sus territorios y sus modos de vida, se propone tomar en cuenta la agencia de los mashco piro al lidiar con este contexto. En este sentido, se plantea recurrir al conocimiento etnológico producido sobre aspectos clave de las sociedades indígenas de la Amazonia (como la guerra, el intercambio y el parentesco), para un entendimiento más completo de su forma de …

The Rise Of Anti-Immigration Populist Radical Right Parties: The Effect Of The Syrian Conflict On Refugee Resettlement And Migration Policies In Germany And Austria, Sara Kouchehbagh

Graduate Theses and Dissertations

The effects of Syrian migration in Europe have revolutionized refugee resettlement globally. Most immigration and refugee problems have historically been settled similarly post WWII, however, Syria is the largest refugee crisis since WWII. It is important to learn how to respond to future conflicts with displacement and resettlement affecting Western countries that are unprepared to respond to a conflict of such magnitude. This thesis will compare previous conflicts and the Syrian conflict, while highlighting the resilient political momentum of reactionary new political groups in European states, particularly Germany and Austria.

Improving Earthquake Disaster Models With Post-Event Data: Insights From The 2015 Gorkha, Nepal Earthquake, Bradley Steven Wilson

Graduate Theses and Dissertations

Immense amounts of data are collected following earthquake disasters. Yet, it remains unclear how researchers’ might take full advantage of diverse post-disaster datasets. Using data from the 2015 Gorkha Nepal earthquake, this dissertation explores three ways in which post- disaster survey and assessment datasets can be used to inform models of seismic risk, vulnerability, and recovery processes. The first article presents an empirical analysis of scale issues in disaster vulnerability indices using a novel dataset of 750,000 households. This study finds that using aggregated household data to create social vulnerability indices can produce results that are meaningfully different from equivalent …

Globally, protected areas offer refugia for a broad range of taxa including threatened and endangered species. In the United States (US), the National Park Service (NPS) manages public lands to preserve biodiversity, but increasing park visitation and development of surrounding landscapes increase exposure to and effects from bioactive contaminants. The risk (exposure and hazard) to NPS protected-stream ecosystems within the highly urbanized southeast region (SER) from bioactive contaminants was assessed in five systems based on 334 pesticide and pharmaceutical analytes in water and 119 pesticides in sediment. Contaminant mixtures were common across all sampled systems, with approximately 24% of the …

Relationships Between Soil Macroinvertebrates And Nonnative Feral Pigs (Sus Scrofa) In Hawaiian Tropical Montane Wet Forests, Nathaniel H. Wehr, Creighton M. Litton, Noa K. Lincoln, Steven C. Hess Oct 2019

Relationships Between Soil Macroinvertebrates And Nonnative Feral Pigs (Sus Scrofa) In Hawaiian Tropical Montane Wet Forests, Nathaniel H. Wehr, Creighton M. Litton, Noa K. Lincoln, Steven C. Hess

United States National Park Service: Publications

Abstract Nonnative feral pigs (Sus scrofa) are recognized throughout the New World as a highly significant introduced species in terms of ecosystem alteration. Similarly, nonnative soil macroinvertebrates (e.g. earthworms, ground beetles) invade and alter the structure and function of native habitats globally. However, the relationship between feral pigs and soil macroinvertebrates remains largely unknown. This study analyzed relationships between these taxa using nine sites located inside and outside of feral pig management units representing a * 25 year chronosequence of removal in tropical montane wet forests in Hawai‘i. Soil macroinvertebrates were sampled from plots categorized as: actively trampled by feral …

Buck Island Reef National Monument (BIRNM), off the coast of St. Croix, US Virgin Islands, harbors critical foraging habitat for Critically Endangered juvenile hawksbills Eretmochelys imbricata that exhibit high site fidelity until sexual maturation. Using an array of fixed passive acoustic receivers that covered over 20.2 km2 at its largest configuration and in-water biannual sampling, we analyzed residency patterns and habitat use of 29 hawksbills. High recapture rates allowed for long- term data collection for some individuals, with …


Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson Oct 2019

Chronic Kidney Disease From Non-Traditional Causes Throughout Central America, Abigail K. Watson

Senior Theses

Throughout many Central American countries, incidence of chronic kidney disease (CKD) has been on the rise. The disease mainly affects agricultural workers and differs from typical CKD. Patients in these countries often do not have preexisting conditions such as diabetes or hypertension known to be traditional causes of CKD. They also experience increased damage to the kidney tubules, rather than the glomeruli generally more heavily impacted. There has been speculation regarding the causes of CKDnT (chronic kidney disease of nontraditional causes), but no consensus has been reached. Two major hypotheses to explain the high prevalence among Central American sugarcane workers …

Nonlinear Reaction–Diffusion Process Models Improve Inference For Population Dynamics, Xinyi Lu, Perry J. Williams, Mevin B. Hooten, James A. Powell, Jamie N. Womble, Michael R. Bower

United States National Park Service: Publications

Partial differential equations (PDEs) are a useful tool for modeling spatiotemporal dynamics of ecological processes. However, as an ecological process evolves, we need statistical models that can adapt to changing dynamics as new data are collected. We developed a model that combines an ecological diffusion equation and logistic growth to characterize colonization processes of a population that establishes long-term equilibrium over a heterogeneous environment. We also developed a homogenization strategy to statistically upscale the PDE for faster computation and adopted a hierarchical framework to accommodate multiple data sources collected at different spatial scales. We highlighted the advantages of using a …
