Rooting For Spices, Carlos Emilio Rodriguez

Open Access Theses & Dissertations

The overarching theme of my thesis combines elements of magical realism with historical people, events, indigenous (Taino/Borike’n) spirituality, and folktales of Puerto Rico. Specifically, I researched, learned, wrote about, and explored the island’s dense history, political struggles, and importance to the colonizing countries of Spain and the United States. The proposed project required significant research time to depict these subjects, people, places, and stories with greater accuracy. I used what I discovered and applied it in chronological sections depicting the island’s historical narrative. I also attempted to employ a process of historical recall referred to as postmemory by Marianne Hirsch. …

8th Position Bodipy Chemistry, Laura I. Saucedo

Open Access Theses & Dissertations

The projects examined in this dissertation demonstrate how the meso substituents N and S lone pair-BODIPY core interaction influence the chemistry and properties of BODIPY fluorophores. Three objectives were completed experimentally and computationally. In the first project the meso amide substituent delocalizes the nitrogen lone pair into the carbonyl, preventing a hemicyanine resonance that causes blue emission in 8-amino-BODIPYs. The second and third projects substituting aniline or phenylthiol derivatives onto the 8th position, respectively. The aniline and phenylthio lone pair interaction with the BODIPY core can be modulated by electron-donating (ED) or –withdrawing (EW) moieties placed para on the aryl …

Transboundary Air Quality Governance: A Case Study Of The Paso Del Norte Air Basin 1940-2000, Laura Margarita Uribarri

Open Access Theses & Dissertations

For thousands of years, the Paso del Norte region which today includes Ciudad Juárez, Chihuahua, El Paso, Texas, and Sunland Park, New Mexico, has been a strategic location by virtue of its geographic positioning at the lowest and easiest passage across the continental divide. During the 19th and 20th centuries as railroad networks connected the region to the far reaches of the U.S. and the interior of Mexico, it became a nexus for natural resource and labor extraction. Mining and smelting industries were later joined by agriculture and manufacturing to benefit from the transportation network and the abundance of labor. …

Pure tungsten is a refractory metal and has been gaining interest for the use in nuclear fusion reactors as a plasma facing material. Titanium Aluminide (TiAl) has been growing in popularity as a possibly to phase out Nickel based superalloys due to its high specific strength at elevated temperatures. These two materials suffer from poor machinability due to being brittle at room temperature. Additive manufacturing (AM) is a recently developed manufacturing method that is fundamentally different than formative or subtractive. AM is a layer-by-layer process that has the potential to manufacture metals to a near net shape. Since the AM …

The Posthuman Paradox: Acknowledging What Matters Through Affective Rhetoricity, Alison Wells Zepeda

Open Access Theses & Dissertations

This dissertation advances a theory of affective rhetoricity through personal narrative and an integrative literature review as a methodological approach. The project draws on a theoretical framework constructed from intra- and extra-disciplinary theories of posthumanism, affect, language, material feminism, object-oriented ontology, new materialism, and rhetoric through which collisions between objects and language are examined as arguments for affective rhetoricity as a revised way of understanding rhetoric’s force. The study culminates with ethical and pedagogical implications for the rhetoric and writing classroom, what it means to enact an ontological disposition toward writing, and an exploration of our human capacity to write …

Translingual Practices For The Development Of Latinx Teacher Candidates: A Pedagogy For The Border, Alcione N. Ostorga

Bilingual and Literacy Studies Faculty Publications

This article explores the application of translingual pedagogies within a course on the development of bilingualism for Latinx bilingual teacher candidates (BTCs) in the U.S.-Mexico borderlands. Using a self-study methodology, it examines the application of translanguaging pedagogies for Latinx BTCs, and their evolving language ideologies. The participants were mostly emergent bilinguals (EBs) whose native Spanish language development was negatively impacted by hegemonic educational practices in the local K-12 schools. Therefore, while the first aim of my pedagogical practices was to promote learning of the content of the course, a second aim was to promote the development of academic Spanish language …

College of Nursing Faculty Research and Publications

Studies have reported different factors associated with anxiety and depression among children and adolescents. However, studies examining the relationship between learning difficulties and internalizing symptoms of Ghanaian children is scarce. The only study available found that 152 students with learning difficulties who visited a psychology clinic for psychological assessment had high levels of stress and anxiety (Asare & Danquah, 2016). While the study provided preliminary evidence of the relationship between learning difficulties and internalizing symptoms, it had some methodological challenges. For instance, the study used a relatively smaller sample size and subsampled children in Accra. Our study used a nationally …

Heavy Sediment Deposition In The Yangtze Estuary, Following Initial Impoundment Of Three Gorges Dam, Boyuan Zhu, Gexuanzi Luo, Yao Yue, Enhang Liang, Alistair G.L. Borthwick, Yitian Li

School of Engineering, Computing and Mathematics

Although the initial impoundment of the Three Gorges Dam in 2003 caused a significant reduction in fluvial sediment load, heavy sediment deposition occurred within the Yangtze Estuary during 2002-2009. To gain a clear recognition of this phenomenon, the present study examines the roles of fluvial water and sediment discharges, coastal dynamics and estuarine engineering projects playing in the Yangtze estuarine erosion-deposition process. Results show that runoff discharge is the dominant factor, performing as that the alternate high and low runoff events in the Yangtze basin are associated with the cycles of morphological erosion and deposition in the Yangtze Estuary. Accordingly, …

Children exposed to parental substance use have a higher likelihood of physical abuse and neglect, and consequently a variety of physical, psychological and cognitive problems. The Enhancing Permanency in Children and Families (EPIC) program is a collaborative effort between the Ohio State University College of Social Work, two county offices of the Ohio Department of Job and Family Services, two juvenile courts and local behavioral health agencies. The goal of EPIC is to use three evidence-based and evidence-informed practices to …

Potential Microplastic Release From Beached Fishing Gear In Great Britain's Region Of Highest Fishing Litter Density, Luka Seamus Wright, Imogen Ellen Napper, Richard C. Thompson

School of Biological and Marine Sciences

While land-based sources of marine plastic pollution have gained widespread attention, marine-based sources are less extensively investigated. Here, we provide the first in-depth description of abandoned, lost or otherwise discarded fishing gear (ALDFG) on northern and southern beaches of the English Southwest Peninsula, Great Britain's region of highest ALDFG density. Three distinct categories were recorded: twisted rope (0.28 ± 0.14 m−1, 17%), braided rope (0.56 ± 0.28 m−1, 33%) and filament (0.84 ± 0.41 m−1, 50%), which likely correspond to fishing rope, net and line. Estimating the disintegration of ALDFG from length and filament number suggests that it has the …

Soil Health Monitoring And Management In Corn And Soybean Agroecosystems Of The Midwestern U.S., Bradley S. Crookston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil health is a concept and condition of the soil where measurable soil properties represent the capacity of a soil fulfilling its intended use, such as producing crops, without constraint to its agro-ecological quality. Soil health assessments are used to estimate the health of a soil by assessing soil biological, chemical, and physical attributes, called soil health indicators, and scoring them on a scale, usually 0 to 100, to guide soil and crop management. However, there are few large-scale analyses of soil health assessment scores and their relationships with crop yield. Understanding how soil health assessments relate to crop yield …

Tractor Connections For Killing Tensors And Their Generalizations, Benjamin D. Shaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

We create new symbolic software tools for the analysis of Killing tensors. Central to our work is the construction of the tractor connection defined on the tractor bundle, which allows one to obtain information about the space of Killing tensors without solving the Killing equations–an approach termed the tractor approach. We give a new application of the tractor approach which allows one to more easily check explicitly for linear independence of a given set of Killing tensors. We develop software to implement such methods in the case of rank 2 Killing tensors; similarly, we develop software to implement analogous methods …

The Rainich equations provide a purely geometrical interpretation of matter in terms of the gravitational field it generates. All this takes place within the geometrical formulation of gravity provided by Einstein’s General Theory of Relativity. Rainich-type conditions giving spacetime "goemetrizations" are reviewed and extended. Three types of matter are considered: perfect fluids, scalar fields, and electromagnetic fields.

The Effects Of Explicitly Teaching Summarization Skills On The Reading Comprehension Of Students With Specific Learning Disabilities, Sherri Lay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Students with reading disabilities struggle with comprehending what they are reading and the necessary strategies to help them understand what they read. Summarizing what was read is a proven strategy for improving reading comprehension. This project examined one strategy for writing summaries called Generating Interactions between Schemata and Text or GIST. Participants included two 7^th grade students and one 8^th grade student who were in Special Education classroom for reading services. The results of this study were inconclusive. Participants showed growth in their summarizing skills, but the growth could not be adequately attributed to the GIST strategy.

Characterizing Relational Values To Inform Message-Framing At The Boa Ogoi Historical Site, Cole G. Stocker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In an increasingly polarized political climate–particularly in the U.S.– environmental issues such as climate change and its effects on the environment have become hot-button partisan talking points resulting in further division. This has led to research on ways to communicate science which does not further inflame political tensions, but rather reinforces and validates the audience’s values. Science communication research provides the foundation for my case study, which focuses on characterizing the environmental values and worldviews of land managers residing and working near the Boa Ogoi Historical Site in southern Idaho. The Northwest Band of Shoshone Nation (NWBSN) is in the …
