Estimation Of Wildlife Damage From Federal Crop Insurance Data, Sophie Mckee, Stephanie A. Shwiff, Aaron M. Anderson

United States Department of Agriculture Wildlife Services: Staff Publications

BACKGROUND: Wildlife damage to crops is a persistent and costly problem for many farmers in the USA. Most existing estimates of crop damage have relied on direct assessment methods such as field studies conducted by trained biologists or surveys distributed to farmers. In this paper, we describe a new method of estimating wildlife damage that exploits federal crop insurance data. We focused our study on four crops: corn, soybean, wheat, and cotton, chosen because of their economic importance and their vulnerability to wildlife damage.

RESULTS: We determined crop-raiding hot spots across the USA over the 2015–2019 period and identified the …

Analysis Of Interdunal Wetlands And Ecosystem Dynamics Using Uas And Obia In Ludington State Park, Michigan, Claire Gilbert

Containing The Blemmye: Anxiety Towards Congenital Difference In The Old English Wonders Of The East, Jessica L. Carrell

Master's Theses

This thesis aims to illuminate early medieval anxieties about sex, procreation, and congenital physical difference by applying a lens of critical disability theory to the Old English Wonders of the East, primarily as it survives in the eleventh-century manuscript, London, British Library, Cotton MS Tiberius B.v. This thesis focuses on the textual and illustrative representation of one Wonder, the Blemmye—an approximately eight-foot-tall, eight-foot-wide androgynous humanoid, whose eyes and mouth are in their chest and who does not possess a head—as a historic embodiment of what disability meant in relation to the early medieval English worldview. This thesis considers the …

Laden With Great Expectations: (Re)Mapping The Arts Housing Policy As Urban Cultural Policy In Singapore, Su Fern Hoe

Research Collection School of Social Sciences

The arts and artists need space to thrive. However, as much of the land in Singapore is state-owned, the finiteness of space – literally and figuratively – remains a key challenge. Yet there is a rich variety of arts infrastructure in Singapore today, from exhibition spaces to performing arts venues and state-subsidised artist studios. This infrastructure comes at a cost - these arts spaces are positioned as policy interventions capable of achieving a broad confluence of cultural, urban, economic and social outcomes for Singapore.

This article aims to provide an understanding of how arts spaces in Singapore has been framed …

In the wake of a policed dystopia that is decreed by both state and social formations, this project develops an understanding of the performance and engagements of policing on racialized queer subjects. Through case and textual analysis, this project examines Black and Brown subjectivities that do the work of imagination, survival, and resistance that contest their possibilities of living. Bringing together Queer theorist and Black Feminist perspectives to define Queer subjectivity, possibility, and the tactical performance of policing- this project creates a theoretical framework about how de-policing Queer and racialized subjectivity and performance can be a life saving strategy that …

Volcanic Record Of The Arc-To-Rift Transition Onshore Of The Guaymas Basin In The Santa Rosalía Area, Gulf Of California, Baja California, Graham Dm Andrews

Faculty & Staff Scholarship

The Gulf of California is an archetype of continental rupture through transtensional rifting, and exploitation of a thermally weakened arc to produce a rift. Volcanic rocks of central Baja California record the transition from calcalkaline arc magmatism, due to subduction of the Farallon plate (ca. 24–12 Ma), to rift magmatism, related to the opening of the Gulf of California (<12 Ma). In addition, a suite of postsubduction rocks (<12 Ma), referred to as “bajaites,” are enriched in light rare-earth and other incompatible elements (e.g., Ba and Sr). These are further subdivided into high-magnesian andesite (with 50%–58% SiO2 and MgO >4%) and adakite (>56% SiO2 and MgO <3%). The bajaites correlate spatially with a fossil slab imaged under central Baja and are inferred to record postsubduction melting of the slab and subduction-modified mantle by asthenospheric upwelling associated with rifting or slab breakoff. We report on volcanic rocks of all three suites, which surround and underlie the Santa Rosalía sedimentary rift basin. This area represents the western margin of the Guaymas basin, the most magmatically robust segment of the Gulf of California rift, where seafloor spreading occurred in isolation for 3–4 m.y. (starting at 6 Ma) before transtensional pull-apart basins to the north and south ruptured the continental crust. Outcrops of the Santa Rosalía area thus offer the opportunity to understand the magmatic evolution of the Guaymas rift, which has been the focus of numerous oceanographic expeditions.

We describe 21 distinct volcanic and hypabyssal map units in the Santa Rosalía area, using field characteristics, petrographic data, and major- and trace-element geochemical data, as well as zircon isotopic data and …

Mapping Geographical Inequalities In Oral Rehydration Therapy Coverage In Low-Income And Middle-Income Countries, 2000-17, Local Burden Of Disease Diarrhoea Collaborators, Ziyad Al-Aly, Et Al

Open Access Publications

BACKGROUND: Oral rehydration solution (ORS) is a form of oral rehydration therapy (ORT) for diarrhoea that has the potential to drastically reduce child mortality; yet, according to UNICEF estimates, less than half of children younger than 5 years with diarrhoea in low-income and middle-income countries (LMICs) received ORS in 2016. A variety of recommended home fluids (RHF) exist as alternative forms of ORT; however, it is unclear whether RHF prevent child mortality. Previous studies have shown considerable variation between countries in ORS and RHF use, but subnational variation is unknown. This study aims to produce high-resolution geospatial estimates of relative …

The Sacred Circle: Ostension In Native American Hoop Dancing, Emma George

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This thesis examines the role of the semiotic concept ostension in folk dance, specifically in Native American hoop dance. Although the discipline of folklore is well-versed in ostension, folk dance has not been examined through this lens. I argue that dance is a form of ostension, of demonstrating a narrative, and this is especially apparent within Native American hoop dancing. I begin with a brief history of Native Americans in North America before discussing the origins of powwows, intertribal culture, and hoop dance. I then look at both the sacred nature and material culture of the modern hoop dance before …

Straight Men Come Out: Queer Eye And The Path To A More Mindful Masculinity, Eli M. Roush

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

My thesis explores the culture surrounding the 2018 reboot of Queer Eye for the Straight Guy in relation to contemporary arguments in masculinity studies about the costs of hegemonic masculinity, performance, and identity. This paper examines how Queer Eye carefully creates space where heteronormative men can safely express emotional vulnerability and embody a more functional masculinity that expands beyond the bounds of hegemonic performance. The bulk of the analysis involves close readings of specific episodes and scenes from Queer Eye that introduce and examine the strategies the Fab Five use to redefine their subject's engagement with masculinity, explore the effectiveness …

Visualizing Effects Of Changing Base Level On Tributary Resources In Lake Powell Reservoir, Madeline Friend

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Lake Powell reservoir is the second-largest reservoir in the United States. As climate change reduces watershed runoff in the Colorado River Basin, questions arise about the management and even existence of Lake Powell. If lake levels continue to drop, what will the emerging canyon look like and what value will we assign it? Lake Powell traps all incoming fine sediment from the Colorado River, the San Juan River, and many smaller tributaries. What is the fate of this sediment under falling reservoir levels and how will it influence other resources? To support a robust public discourse, we provide an immersive …

Protecting Crops From Abiotic Stress: Copper Oxide Nanoparticle Effects On Wheat And A Beneficial Rhizobacterium, Matthew Potter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nanoparticles (NPs) are defined as particles less than 100 nm in at least one dimension. CuO NPs have possible applications in agriculture as micronutrient sources, pesticides, and enhancers of crop stress tolerance. Here, three aspects of CuO NP agricultural applications are studied: 1) the potential of CuO NPs to prevent wheat lodging-when crops irreversibly fall over; 2) CuO NP-induced drought tolerance in wheat seedlings; and 3) the effects of CuO NPs on outer membrane vesicle (OMV) production by Pseudomonas chlororaphis O6 (PcO6), a plant-health promoting bacterium.

Wheat grown 7 d exposed to CuO NPs in the growth matrix …

Try The Wine: Food As An Expression Of Cultural Identity In Roman Britain, Molly Reininger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research surrounding cultural identity and food customs throughout history are published often, but any research that attempts to combine the two are often based in more recent history. Few combinations of the two are available, and fewer explore the implications within ancient colonization and expansion.

The research for this thesis was conducted with three viewpoints in mind: the colonization of Britannia from Romans within the new colony, the colonization from the native Briton's perspective, and the Roman citizens within Britannia at the end of Rome's military involvement with the colony. This method was chosen because in the early years of …

Rome, Robes, And Rivers: Land, Water, And Power In The Aniene Valley, Jonah R. Bibo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rome, Robes, and Rivers is a multi-century environmental history that shows how different occupants in the Italian Aniene river valley help power through the exploitation and control of its land and water resources. It ranges from the classical to late medieval eras, focusing on the Roman empire alongside later Benedictine monastic societies, who each used different tactics to maintain control over the land. Roman aqueducts brought water to the city, while Benedictine monks taxed peasant laborers to maintain control of the land. Each occupant shaped the land their own needs and left their mark on the landscape in ways that …

Private Insurance Limits And Responses, Elizabeth Weeks

Scholarly Works

The COVID-19 pandemic exposed a number of existing flaws in the United States’ patchwork approach to paying for and providing access to medical care. Shelter-in-place orders, social distancing, and other public health strategies employed to address the pandemic spawned a global recession, causing rapid and high unemployment rates in many countries. The U.S. unemployment rate peaked in April 2020 at 14.7%, higher than in any previous period since World War II. The United States has long hewed an anachronistic policy of relying heavily on private employers to provide health insurance to a substantial portion of the population. Those who are …
