Nonprofit Accountability: Effects Of Subsector On Online Accountability, Ibrahima F. Yaro, Trent A. Engbers

Midwest Social Sciences Journal

Scandals within the nonprofit sector over compensation and management have increased calls for nonprofits to demonstrate accountability. Many organizations have responded by disclosing information online and providing tools that allow web-based interactions with stakeholders. The literature on nonprofits’ online accountability has found that the level of nonprofit online accountability is affected by their size, age, asset, revenue, and location, but hasn’t been examined in terms of how subsector influences online accountability. Through a web-content analysis of fifty-five nonprofits, this research investigated how subsector (arts and culture, education, health, and human services) influences online accountability using a framework of four types …

Human–Environment Interactions At Ta’Ab Nuk Na, A Submerged Maya Salt Works Site In Belize, Cheryl M. Foster, Heather Mckillop, Cory Sills

Geography Faculty Publications and Presentations

Sea-level rise and settlement are investigated at Ta’ab Nuk Na, an ancient Maya salt works in Belize, by examining samples from wooden posts and marine sediment. The samples included Post 145 of Building B and the Nunavut beam, along with marine sediment columns cut from beside both wooden posts. The sediment columns were sampled at 2 cm intervals. Loss-on ignition confirmed the presence of organic material. Identifying the organic content involved removing nonorganic material from the sediment and sorting the organic material under magnification. This procedure established that most of the organic material was red mangrove (Rhizophora mangle). Red mangroves …

U-Net-Stn: A Novel End-To-End Lake Boundary Prediction Model, Lirong Yin, Lei Wang, Tingqiao Li, Siyu Lu, Zhengtong Yin, Xuan Liu, Xiaolu Li, Wenfeng Zheng

Faculty Publications

Detecting changes in land cover is a critical task in remote sensing image interpretation, with particular significance placed on accurately determining the boundaries of lakes. Lake boundaries are closely tied to land resources, and any alterations can have substantial implications for the surrounding environment and ecosystem. This paper introduces an innovative end-to-end model that combines U-Net and spatial transformation network (STN) to predict changes in lake boundaries and investigate the evolution of the Lake Urmia boundary. The proposed approach involves pre-processing annual panoramic remote sensing images of Lake Urmia, obtained from 1996 to 2014 through Google Earth Pro Version 7.3 …

Object-Oriented Remote Sensing Approaches For The Detection Of Terrestrial Impact Craters As A Reconnaissance Survey, Habimana Emmanuel, Jaehyung Yu, Lei Wang, Sung Hi Choi, Digne Edmond Rwabuhungu Rwatangabo

Faculty Publications

The purpose of this study is to employ a remote sensing reconnaissance survey based on optimal segmentation parameters and an object-oriented random forest approach to the identification of possible terrestrial impact craters from the global 30-m resolution SRTM DEM. A dataset consisting of 94 confirmed and well-preserved terrestrial impact craters, 104 volcanic calderas, and 124 valleys were extracted from real-world surface features. For craters with different sizes, eight optimal scale parameters from 80 to 3000 have been identified using multi-resolution segmentation, where the scale parameters have a positive correlation (R2 = 0.78) with the diameters of craters. The object-oriented random …

The Bearing Earth: Colonization, Conservation, And Political Ecology In Costa Rica (Coto Brus 1948 - Present), Pablo Alonso Arias-Benavides

Latin American Studies ETDs

This thesis presents two questions: How are relationships between people in Coto Brus and the land – specifically, forest – mediated by social, political, and economic forces? How are personal and collective identities expressed through relationship with the landscape? I chose Coto Brus because it is a forested region of Costa Rica which was populated with state support in the 1950s, and because it is my father’s hometown. In order to understand the subjective experiences of Costa Ricans involved in deforestation and reforestation, I performed interviews in the canton, visited conservation sites, and analyzed historical sources. This study combines multiscale …

Animal Welfare Deserts: Human And Nonhuman Animal Inequities, Laura Reese, Xiaomeng Li

School of Global Integrative Studies: Faculty Publications

Residents of distressed areas of inner cities have less access to many of life’s necessities and amenities than their more well-off counterparts. Geographic proximity has been identified as a primary barrier to accessing care for pets potentially creating animal welfare deserts. This project addresses three questions: Are there visible animal welfare deserts in distressed urban centers?; What human inequities are most strongly related to animal welfare deserts?; and What might be done to address these inequities? Using business location and census data in the city of Detroit, this research identifies distinct animal welfare deserts finding that more prosperous areas have …

Refining 2svca Method For Measuring Telehealth Accessibility Of Primary Care Physicians In Baton Rouge, Louisiana, Lingbo Liu, Jennifer Alford-Teaster, Tracy Onega, Fahui Wang

Faculty Publications

Equity in health care delivery is a longstanding concern of public health policy. Telehealth is considered an important way to level the playing field by broadening health services access and improving quality of care and health outcomes. This study refines the recently developed “2-Step Virtual Catchment Area (2SVCA) method” to assess the telehealth accessibility of primary care in the Baton Rouge Metropolitan Statistical Area, Louisiana. The result is compared to that of spatial accessibility via physical visits to care providers based on the popular 2-Step Floating Catchment Area (2SFCA) method. The study shows that both spatial and telehealth accessibilities decline …

Marginal To Whom? Reflections On Gow’S "Purús Song", Magnus Course

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

This paper constitutes a personal exploration of the impact of the work of Peter Gow on my own attempts to think through specific ethnographic problems, both in the Mapuche communities of Southern Chile and the Gaelic communities of Western Scotland. I focus in particular on how Gow’s lesser-known essay “Purús Song” inverts received wisdom about the relationships between center and periphery, and between nation-state and Indigenous people. I see this as one iteration of Gow’s broader aim of letting ethnographic realities transform theoretical complacencies.

Indigenous Transformations In The Comunidad Nativa: Rethinking Kinship And Its Limitations In An Expanding Resource Frontier, Evan Killick, Juan Pablo Sarmiento Barletti

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

In Of Mixed Blood, Peter Gow sets out an account of the transformations of kinship and the construction of social relations among Indigenous, mainly Yine (Piro), people of the Bajo Urubamba valley in the early 1980s, when Peru’s “Comunidades Nativas” (“Native Communities”) were receiving their new official titles. We revisit Peter’s proposition by comparing it our more recent ethnographic engagements with Indigenous Asháninka/Ashéninka communities in the region. While tracing continuities from his observations, we also show how social relations now play out in different ways, as certain important resources have become scarcer and the need for …

Civilized Elders And Isolated Ancestors: The Multiple Histories Of Contemporary Amazonia, Casey High

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

In this article I consider the impact of Peter Gow’s writing on indigenous histories as a key area of research on Amazonia. Building on his study of kinship as history on the Bajo Urubamba (1991) he presented a regional perspective on the dynamic social categories by which Amazonian people understand their relations with various “others.” Focusing on indigenous agency and modes of thought, Gow challenged certain lines of historical thinking that dominated anthropology at the time. I explore how his ethnographic approach to history has influenced a generation of regional scholarship, including my own work on memory and social transformation …

Desire, Difference, And Productivity: Reflections On “The Perverse Child” And Its Continued Relevance, Christopher Hewlett

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

This article is concerned with the relationships through which children have been born, raised, and made into Amahuaca people over the past 75 years, and within contemporary Native Communities on the Inuya River since their formation beginning in the 1980s. The process of making children into kin among Amahuaca people is similar to that described throughout much of lowland South America. The production, preparation, and sharing of proper food (manioc, plantains, fish, and game) as well as manioc beer are central aspects of sociality and the formation of specific kinds of bodies. While the processes of sharing substances, demonstrating care, …

Between Cocama And Modernity In The Ucamara (Peruvian Amazon), Marta Krokoszyńska

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

Combining a contemporary ethnographic perspective with a review of historical records, the article extends Peter Gow’s re-reading of the ex-Cocama phenomenon in the Western Amazon. It argues that the foundation of the Amazonian Peruvian town of Requena at the beginning of the 20th century took place during an important historical moment in the region. Within the post-rubber boom context, schools became a particularly important idiom that enabled Requena’s growth as the centre of education and modernity. The paper investigates relations between the widespread desire for education in the Ucamara region, and Cocama descendants’ and other “ribereño” ex-Mainas peoples’ specific notions …

Contrasting Responses Of Atlantic And Pacific Tropical Cyclone Activity To Atlantic Multidecadal Variability, Huanping Huang, William D. Collins, Christina M. Patricola, Yohan Ruprich-Robert, Paul A. Ullrich, Alexander J. Baker

Faculty Publications

This research assesses the influences of Atlantic Multidecadal Variability (AMV) on global tropical cyclones (TCs) using two large ensembles of idealized global climate model simulations with opposite signs of AMV forcings superimposed (i.e., AMV+ and AMV–). We first detect TCs and then compare TC activity by basin in the two AMV experiments. We find contrasting responses of Atlantic and Pacific TC frequency to the AMV anomalies. Compared to AMV–, AMV+ significantly increases TC frequency in the North Atlantic, including those making landfalls. The increase is explained by warmer sea surface temperature, higher relative humidity, increased relative vorticity, and weaker vertical …

The response of the hydrological cycle to anthropogenic climate change, especially across the tropical oceans, remains poorly understood due to the scarcity of long instrumental temperature and hydrological records. Massive shallow-water corals are ideally suited to reconstructing past oceanic variability as they are widely distributed across the tropics, rapidly deposit calcium carbonate skeletons that continuously record ambient environmental conditions, and can be sampled at monthly to annual resolution. Climate reconstructions based on corals primarily use the stable oxygen isotope composition (δ18O), which acts as a proxy for sea surface temperature (SST), and the oxygen isotope composition of seawater (δ18Osw), a …

To Open A Clearing: Cultivating Spaces Of Endurance In The Upper Amazon, Brunno De Melo Meirelles Douat

Masters of Environmental Design Theses

To effectively challenge the policies of extraction implemented by late liberal regimes, the Waorani communities from Upper Amazon have devised spatial strategies to defend their traditional territory. By re-examining the concept of the contact zone and unfolding settler and Indigenous literature, spatialities, and worldviews, this thesis suggests the concept of forest Clearings as a means to explore spatial forms of endurance.

Clearings emerge within the Amazon in sites where encounters between divergent worldviews embody otherwise modes of existence. Through a series of fieldwork reflections, these Clearings are perceived as spaces where ontological negotiations are more likely to occur, strategies of …

Operation Summer Care: Territories Of The Stewardship-Hospitality Complex, George Papamattheakis

Masters of Environmental Design Theses

Operation Summer Care studies the expanding interest that the hospitality industry takes in the biogeophysical environment. Natural surroundings have long been an essential operational precondition of tourism in the global sunbelt, but contemporary environmental anxieties increasingly motivate different strata of hosts to take a more active role in environmental management. Usually the domain of the state, biogeophysical entities and their spaces—plants and animals, sand formations, wetlands, entire ecosystems and protected areas—are measured, ordered, and managed by actors adjacent to the tourism industry. At the same time, the socio-technical mechanisms of environmental intervention and calculation are conveniently framed as practices of …

One original feature is the focus on mobility, how indispensable it is in modern societies, how it is disrupted by extreme weather, and …

The Manito Topos Project: Place Naming And Toponymic Silencing In The Sierras Of Northern Nuevo México And Southern Colorado, Len N. Beké

Spanish and Portuguese ETDs

This dissertation reports on documentary research on vernacular toponymies in Manito communities in Nuevo México and Colorado. These toponymies are erased, obscured and delegitimized in official maps. Within the study area, vernacular antecedents for 49.5% of official names for natural features were documented, along with 280 previously unmapped names. These data were compared to the state-sanctioned toponymy to determine a typology of linguistic mechanisms of toponymic silencing. While a majority of official toponyms are based on Manito oral tradition, only 15.4% of the labels for natural features represent unaltered versions of names in that tradition. This dissertation theorizes the conceptual …

Geographic Object-Based Image Analysis For Archaeological Site Detection: A Case Study For The Chicama Valley, Peru, Cesca Craig

Anthropology Undergraduate Honors Theses

This study represents a first attempt at applying geographic object-based image analysis (GEOBIA) for the detection of extant archaeological sites in the Chicama River Valley located in northern coastal Peru. This region is characterized by the presence of mound-like archaeological sites dispersed throughout large-scale agricultural fields. High-resolution multispectral imagery from Planet Labs was used in this study because of its high spatial and temporal resolution and availability at no cost through Planet’s Education and Research Program. The main goal for this study was to explore GEOBIA as an approach to archaeological site detection and assess the feasibility of developing exportable …

Faculty Publications

Cotton plays an essential role in global human life and economic development. However, diseases such as leaf blight pose a serious threat to cotton production. This study aims to advance the existing approach by identifying cotton blight infection and classifying its severity at a higher accuracy. We selected a cotton field in Shihezi, Xinjiang in China to acquire multispectral images with an unmanned airborne vehicle (UAV); then, fifty-three 50 cm by 50 cm ground framed plots were set with defined coordinates, and a photo of its cotton canopy was taken of each and converted to the L*a*b* color space as …

Study On The Thermospheric Density Distribution Pattern During Geomagnetic Activity, Lirong Yin, Lei Wang, Lijun Ge, Jiawei Tian, Zhengtong Yin, Mingzhe Liu, Wenfeng Zheng

Faculty Publications

The atmospheric density of the thermosphere is a fundamental parameter for spacecraft launch and orbit control. Under magnetic storm conditions, the thermospheric atmospheric density experiences significant fluctuations, which have a negative impact on spacecraft control. Exploring thermospheric density during geomagnetic storms can help to mitigate the effects of such events. Research on the inversion of accelerometer measurements for different satellites and the variations of atmospheric density under extreme conditions is still in its infancy. In this paper, the distribution of atmospheric density during three geomagnetic storms is investigated from the inversion results of the Swarm-C accelerometer. Three major geomagnetic storms …

Multidecadal Pre- And Post-Collapse Dynamics Of The Northern Larsen Ice Shelf, Shujie Wang, Hongxing Liu, Richard B. Alley, Kenneth Jezek, Patrick Alexander, Karen E. Alley, Zhengrui Huang, Lei Wang

Faculty Publications

Rapid retreat of Antarctic ice shelves in a warmer climate remains challenging to predict, contributing to uncertainties in projections of sea level rise. The collapse of the Larsen B Ice Shelf on the Antarctic Peninsula in 2002 was perhaps the most dramatic example of ice shelf retreat on record. Despite a general consensus that regional climate warming is associated with ice shelf collapse, knowledge of the precise details leading to and following collapse is limited. Here we examine a comprehensive set of satellite observations, modeling experiments, and climate reanalysis data to elucidate calving behavior, flow dynamics, and mechanical conditions of …

Geophysical, Archaeological, And Geospatial Investigations At Presidio Los Adaes, 18th Century Capital Of Spanish Texas, Robert Linam

Electronic Theses and Dissertations

Presidio Los Adaes (16NA16), located in present day northwest Louisiana, served as the capital of Spanish Texas for much of the 18th century. Maps and historical documents provide architectural plans for the fort and other buildings on the site but differ in the size and location of several buildings. In 2009, a geophysical survey of the site with ground penetrating radar, magnetometry, electrical resistance, and electromagnetic induction showed good preservation of architectural foundations. Visual assessment of the maps and geophysical data, information from archaeological excavations, and spatial statistics suggests that the fort was originally built as specified by the architect, …

We Are Gullah: A Community Approach To Preserving Gullah Geechee Historical Sites Of Significance, Peter Gaytan

All Theses

The National Register of Historic Places is an inventory established by the National Historic Preservation Act of 1966 that identifies architectural and archaeological sites significant to American history. The National Register was created to encourage the documentation, evaluation, and protection of America’s historic resources. Over 96,000 historic properties, sites, and structures are currently listed on the National Register. Despite the number of historic places listed on the National Register there is still an overwhelmingly low number of sites listed on the National Register relating to underrepresented communities. This thesis assessed the definition of significance laid out in the National Register …

China's Public Diplomacy Philosophy, Logan Webb

ATU Scholars Symposium

China has become a giant in the globalized world in such a short period of time. This led me to the research question, “What is China’s public diplomacy philosophy?” Using a textual analysis of major geopolitical events that China is involved in (The Belt and Road Initiative, the South China Sea dispute, Uyghur imprisonment, and the Hong Kong government takeover) and the history of China since the Chinese Civil War, it becomes apparent that the country uses the concept of hard and soft power for its public diplomacy. If a country is not receptive to China or its intended actions, …
