Una Víctima Del Encuentro Emergente Entre Mundos, Minna Opas, Yulissa Trigoso Zorrilla Dec 2019

Una Víctima Del Encuentro Emergente Entre Mundos, Minna Opas, Yulissa Trigoso Zorrilla

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

En febrero de 2018, Víctor Zorrilla, un hombre Yine de mayor edad que vive en el sudeste de Perú, fue asesinado por los mashco piro mientras estaba cazando. Zorrilla se había encontrado con los mashco piro, los que consideraba como parientes, nomolene, varias veces durante décadas, pero eso no le impidió llegar a ser víctima de un emergente encuentro entre mundos. A través de un relato personal de sus encuentros con los mashco piro en la década de 1980, este artículo plantea y examina varias cuestiones focales relacionadas con el aislamiento voluntario. ¿Cómo se puede adquirir conocimiento sobre los …

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 …

Yine Manxinerune Hosha Hajene E A Territorialidade Na Terra Indígena Mamoadate, Brasil: O Poder Das Memórias, Lucas Artur Brasil Manchineri, Pirjo Kristiina Virtanen, Maria Luiza Ochoa

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.

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 …


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 …


Grandes Interrogações Sobre O Futuro Dos Povos Indígenas Isolados, Conselho Indigenista Missionário Dec 2019

Grandes Interrogações Sobre O Futuro Dos Povos Indígenas Isolados, Conselho Indigenista Missionário

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

O presente artigo, de autoria coletiva da equipe do Conselho Indigenista Missionário (Cimi), pretende traçar um quadro geral da situação de vulnerabilidade dos povos indígenas em isolamento e contato inicial no Brasil, tendo como referência temporal o ano de 2016. É preocupante o avanço da exploração dos recursos naturais em territórios ocupados por esses povos, principalmente com a mineração e a exploração de madeira, seja dentro de terras indígenas destinadas aos povos em isolamento, em terras indígenas partilhadas por outros povos, ou em territórios onde a proteção ou o reconhecimento pelo Estado não se faz presente.

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 Dec 2019

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 …

United States National Park Service: Publications

Understanding the spatial ecology of highly mobile marine vertebrates is necessary for informing conservation and management strategies aimed at protecting such species. 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 Sep 2019

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 …


Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman Sep 2019

Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman

United States National Park Service: Publications

Permafrost thaw in the Arctic is mobilizing old carbon (C) from soils to aquatic ecosystems and the atmosphere. Little is known, however, about the assimilation of old C by aquatic food webs in Arctic watersheds. Here, we used C isotopes (d13C, D14C) to quantify C assimilation by biota across 12 streams in arctic Alaska. Streams spanned watersheds with varying permafrost hydrology, from ice-poor bedrock to ice-rich loess (that is, yedoma). We measured isotopic content of (1) C sources including dissolved organic C (DOC), dissolved inorganic C (DIC), and soil C, and (2) stream biota, including benthic biofilm and macroinvertebrates, and …


Social Interactions Do Not Drive Territory Aggregation In A Grassland Songbird, S.K. Winnicki, S.M. Munguia, E.J. Williams, W.A. Boyle Aug 2019

Social Interactions Do Not Drive Territory Aggregation In A Grassland Songbird, S.K. Winnicki, S.M. Munguia, E.J. Williams, W.A. Boyle

United States National Park Service: Publications

Understanding the drivers of animal distributions is a fundamental goal of ecology and informs habitat management. The costs and benefits of colonial aggregations in animals are well established, but the factors leading to aggregation in territorial animals remain unclear. Territorial animals might aggregate to facilitate social behavior such as (1) group defense from predators and/or parasites, (2) cooperative care of offspring, (3) extra-pair mating, and/or (4) mitigating costs of extra-pair mating through kin selection. Using experimental and observational methods, we tested predictions of all four hypotheses in a tallgrass prairie in northeast Kansas, United States. Grasshopper Sparrow (Ammodramus savannarum) males …

Vegetation Monitoring At Homestead National Monument Of America, Nebraska, 1998–2017, Sherry A. Leis

United States National Park Service: Publications

Executive Summary

The Heartland Inventory and Monitoring Network has sampled permanent monitoring sites in three vegetation community types (restored prairie, successional forest, and bur oak forest) at Homestead National Monument of America since 1998 (includes nine sample years). Network scientists record each species, aerial cover estimates of ground flora, diameter at breast height of midstory and overstory trees, and tree regeneration frequency (tree seedlings and saplings) within these permanent sites.

The park has experienced similar periods of drought and wetness through the monitoring record. Ground cover estimates indicate that prairie litter and bare ground are negatively related; prescribed fire cycles …


How Pennsylvanians Define Environmental Justice, Kayla Hofmann Jul 2019

How Pennsylvanians Define Environmental Justice, Kayla Hofmann

Sociology Summer Fellows

The Pennsylvania Department of Environmental Protection (DEP) defines an environmental justice area as any census tract that partially or wholly includes a 30 percent or greater minority population or 20 percent or more of a population living in poverty. However, little is known about how the average Pennsylvanian defines environmental justice, hindering our ability to determine whether the current definition is adequate. Using transcripts from nine listening sessions on the DEP’s tour of affected counties, I address 3 questions: (1) How do people define environmental justice? (2) What do people think are the most pressing issues in each county? And …
