An Investigation Into The Role Of Geometrically Necessary Dislocations In Multi-Strain Path Deformation In Automotive Sheet Alloys, Rishabh Sharma

Theses and Dissertations

Multiple strain path changes during forming lead to complex geometrically necessary dislocation (GND) development in strain gradient fields, inducing internal stresses that contribute to the Bauschinger effect, residual stresses, and springback which alters the final geometrical shape of the part. In order to analyze and design improved processing routes, models must capture the evolution of these internal stresses. However, most models capture the effects of these stresses via phenomenological approaches that require calibration to each new material and strain path. The development of models that capture the underlying physics at the sub-grain level is underway but requires in-depth studies of …

Pollination Ecology Of Island Endemic Plants: A Case Study On The California Channel Islands, C. Sheena Sidhu, Giselle E. Lozano, Michelle C. Miner, Emily Howe, Erin E. Wilson-Rankin

Western North American Naturalist

Understanding the pollination requirements of threatened species is critical for the success of long-term conservation strategies. In a series of greenhouse experiments, we assessed the effects of different pollination treatments, including autogamy, facilitated autogamy, and cross-pollination on fruit and seed set for 2 generations of a rare island endemic plant. Santa Cruz Island rockcress, Sibara filifolia (Brassicaceae), is a rare, endangered annual herb that is endemic to the California Channel Islands. While efforts are underway to monitor and conserve this rare plant species, little is known about its pollination biology. We quantified the index of self-compatibility and multiplicative fitness. We …

Methods For Single-Cell And Low-Input Proteomics, Yiran Liang

Theses and Dissertations

Single-Cell Proteomics (SCP) can provide unique insights into biological processes by resolving heterogeneity that is obscured by bulk measurements. Gains in the overall sensitivity and proteome coverage through improvements in sample processing and analysis increase the information content obtained from each cell, particularly for less abundant proteins. In addition to achieving in-depth proteome coverage from single cells, higher throughput measurements enable large-scale and statistically significant features within single cell populations. This dissertation focuses on method development to improve the sensitivity and throughput of SCP based on the nanoPOTS (nanodroplet Processing in One pot for Trace Samples) platform. The methods discussed …

Fault Tolerant Robotics Using Active Diagnosis Of Partially Observable Systems And Optimized Path Planning For Underwater Message Ferrying, Devon M. Webb

Theses and Dissertations

Underwater robotic vehicles are used in a variety of environments that would be dangerous for humans. For these vehicles to be successful, they need to be tolerant of a variety of internal and external faults. To be resilient to internal faults, the system must be capable of determining the source of faulty behavior. However many different faults within a robotic vehicle can create identical faulty behavior, which makes the vehicles impossible to diagnose using conventional methods. I propose a novel active diagnosis method for differentiating between faults that would otherwise have identical behavior. I apply this method to a communication …

Sitting Time And Insulin Resistance In 6,931 United States Adults: The Role Of Abdominal Adiposity, Kayla Marie Parker

Theses and Dissertations

This cross-sectional investigation of 6,931 U.S. adults examined the relationship between sitting time and insulin resistance. A primary objective was to evaluate how this relationship was mediated by the following variables: age, sex, race, year of assessment, cigarette smoking, physical activity, body mass index (BMI), and waist circumference. Self-reported sitting time, measured in minutes per day, was the exposure variable. Insulin resistance, indexed by the homeostatic model assessment of insulin resistance (HOMA-IR), was the outcome variable. Data were used from the 2011-2018 National Health and Nutrition Examination Survey (NHANES). Results showed a strong, positive association between sitting time and insulin …

This review considers Ellen C. Carillo's The Hidden Inequities in Labor-Based Contract Grading, an important contribution that examines labor-based grading contracts through a disability studies lens.

Student Interpretation And Use Arguments: Evidence-Based, Student-Led Grading, Ll Aull

Journal of Response to Writing

Assigning grades is conventionally the exclusive, lonely terrain of the instructor, even as other aspects of teaching and responding to student writing are collaborative. As an alternative that promotes student engagement and agency, labor-based contract grading is used in a growing number of writing classrooms. This article strives to add to these conversations by describing evidence-based, student-led grading as an option that engages students as well as a broad construct of writing. This approach foregrounds students’ own response to their writing, in the form of evidence-based interpretation and use arguments for their grades. It engages students in the process of …

Feedback Conversations: An Activity To Initiate Instructor-Student Dialogues About Writing Development, Sarah M. Lacy

Journal of Response to Writing

In this essay I discuss the pedagogical implications of a classroom activity in which students work reflectively with instructor feedback provided to their writing. Using the comments feature in Google Docs, these “Feedback Conversations” create a dialogue between student and instructor using feedback as the exigence for collaboration in developing a student’s writing process. This activity addresses the work of Anthony Edgington (2020) and Pamela Gay (1998), by offering an exercise which allows instructors to remain reflective on their feedback practices, while also instigating a “conversation” between student and instructor. By offering a virtual space to house this conversational exercise, …

Crafting A Writing Response Community Through Contract Grading, Sarah Klotz, Kristina Reardon

Journal of Response to Writing

As labor-based grading contracts gain momentum in first year writing classrooms, new kinds of response to writing take center stage. We explore how session notes composed by embedded peer tutors and students become rich tools in a writing process and create a gateway to the writing center for first-year students. By reading session notes in conversation with students’ reflective writing, we put forward three key findings: students articulate a relationship between building confidence in their writing and their willingness to seek, receive, and value feedback; students discuss how the labor required for an ‘A’ pushed them to access and learn …

Feedback As Boundary Object: Intersections Of Writing, Response, And Research, Lindsey Harding, Joshua King, Anya Bonanno, Joseph Powell

Journal of Response to Writing

While a great deal is known about instructor response to student writing—from commenting practices to student perceptions—less is known about how feedback impacts students’ writing and writerly development. While we set out to study students’ explicit engagement with written instructor feedback, our initial experimental design was disrupted by the COVID-19 pandemic. Accordingly, we describe the dialogic collaborative process that emerged as we considered both the data we were able to collect and, in turn, feedback anew. This article proposes that feedback on student writing is a boundary object which affords those interacting with it the opportunity for collaboration despite the …

Feedback Practices In Hybrid Writing Courses: Instructor Choices About Modality And Timing, Ariel M. Goldenthal, Jessica Matthews, Courtney Adams Wooten, Brian Fitzpatrick, Lourdes Fernandez

Journal of Response to Writing

Despite a wealth of research on feedback practices in synchronous and asynchronous courses, little has been done to investigate such practices in hybrid writing pedagogy. How do instructors make choices about providing feedback when both instructional modes are operating in a course?

A qualitative study conducted with fourteen instructors who teach hybrid writing courses at a large state university reveals how they navigate a series of choices about providing feedback on student writing. This study shows that instructional modality, use of the LMS, and labor conditions influence the decisions instructors make about how and when to provide feedback, especially on …

Using Lessons From Collaboratively Processing Written Corrective Feedback, Nicholas Carr

Journal of Response to Writing

This case study investigates how two English language learners use knowledge co-constructed while collaboratively processing written corrective feedback (WCF) on jointly produced texts. It does so through the lens of sociocultural theory (SCT). This study extends the extant literature by investigating how co-constructed knowledge emerging from their interactions was manifested in subsequent individual writing and speaking tasks which were similar—but not identical—to the original collaborative writing tasks. Data were collected from video recordings of participants’ interactions as they collaboratively processed WCF; individual retrospective interviews, during which participants watched the video recordings and identified what they learned; and observation of individual …

Ascat Wind Estimation At 2.5 Km Resolution Supported By Machine Learning Rain Detection, Joshua Benjamin Kjar

Theses and Dissertations

The Advanced Scatterometer (ASCAT) is a C-band scatterometer designed to be less sensitive to rain contamination than other higher frequency scatterometers. However, the radar backscatter is still affected by rain which increases error during wind estimation. The error can be reduced in rainy conditions by combining a rain backscatter model with the existing wind only (WO) backscatter model to perform simultaneous wind and rain (SWR) estimation. I derive and test several 2.5 km resolution rain backscatter models for ASCAT data which are used with the WO model to estimate the near surface winds. Various rain models optimal for different purposes …

“I Suppose An Island Dweller Should Expect It To Be So”: The Contradiction And Drama Of Maternity And Islands In Caleb’S Crossing, Shayla Frandsen

Criterion: A Journal of Literary Criticism

Islands have a long tradition of capturing human imagination and functioning as a space that nurtures both magic and mystery. As geographic locations, they seem to avoid easy taxonomy even while behaving easily categorizable: they exist as tourist fantasies separate from everyday landscape even while many operate as an othered land that is still “safe” enough to visit. They are isolated yet capable of nurturing strong cultural identity. They also act as autonomous entities while still being interconnected within larger natural structures, coastlines, and waterways. In these ways and more islands navigate as border spaces of inherent contradiction—contradictions which are …

To The Lighthouse Or To Mrs. Ramsay? A Study Of Materialization Through The Symbolism Of The Lighthouse In Virginia Woolf’S To The Lighthouse, Virginia Moscetti

Criterion: A Journal of Literary Criticism

In this paper, I argue that the “lighthouse” in Virginia Woolf’s novel To The Lighthouse operates as a symbol for Mrs. Ramsay’s “self-hood” and for Mr. Ramsay’s obscure desire for sanctuary and domesticity in Mrs. Ramsay. Through this symbolism I further contend that Woolf renders the ambiguous processes associated with self-hood and desire materially legible and, in doing so, demonstrates how metaphor and symbolism reconstitute our material world into representation. Moreover, I argue that we can conceptualize the lighthouse symbolism revolving around and centered in Mrs. Ramsay in terms of T.J. Clark’s “dual figure”; a figure with two symbolic connotations …

Character First: Defining And Methodizing Character Depth, Jeff Mason

Criterion: A Journal of Literary Criticism

By looking into significant literary theory, contemporary works of story, and even elements of mathematics, this paper advances our understanding of characters and how they create meaning in stories.

Marriage And Relationships In Art Spiegelman’S Maus: The Erasure Of The Female Experience, Gretchen K. Picklesimer Kinney

Criterion: A Journal of Literary Criticism

In this paper, the author explores how Vladek’s focus on money, control, and independence creates an imbalance of power in his romantic relationships with Luica, Anja, and Mala. She explores Vladek’s motivations for continuing (or not continuing) these relationships, and how Vladek tries to maintain power and control. She analyzes how Vladek ignores the perspectives and experiences of these women to create his own biased narrative of the relationships.

The Applicability Of Joint Source-Channel Coding Systems To Aeronautical Mobile Telemetry Data, Jesse Richmond

Theses and Dissertations

Broadcast spectrum restrictions require greater efficiency from wireless transmission systems, particularly in applications where sections of spectrum previously reserved for military purposes have been sold to private interests. A joint source-channel coding system, in tandem with smart data selection techniques, is proposed as a potential solution to this problem. The workings of this joint source-channel coding system are detailed, with particular attention given to the decoding process.

Building Software Compliant Multidimensional Datasets Through Programmatic Solutions, Jon Enoch Jones

Theses and Dissertations

Meteorological and other multidimensional, georeferenced data is used extensively in science and engineering. These datasets are produced, shared, and used by organizations all over the world. Conventions have been developed specifying the metadata and format of these datasets in an effort to standardize the data and make it compatible with current and future software and web services. By necessity, the conventions are complex and difficult to implement correctly, resulting in useful datasets that are unusable in many applications due to lack of compliance with the conventions. By programmatically assigning metadata and guiding the dataset creator through the dataset creation process, …

Hybrid Machine Learning And Physics-Based Modeling Approaches For Process Control And Optimization, Junho Park

Theses and Dissertations

Transformer neural networks have made a significant impact on natural language processing. The Transformer network self-attention mechanism effectively addresses the vanishing gradient problem that limits a network learning capability, especially when the time series gets longer or the size of the network gets deeper. This dissertation examines the usage of the Transformer model for time-series forecasting and customizes it for a simultaneous multistep-ahead prediction model in a surrogate model predictive control (MPC) application. The proposed method demonstrates enhanced control performance and computation efficiency compared to the Long-short term memory (LSTM)-based MPC and one-step-ahead prediction model structures for both LSTM and …

The Only Way Out Is Through: Community, Death, And The Desacralization Of Trauma In George Saunders’ Lincoln In The Bardo, Josey Gardner

Criterion: A Journal of Literary Criticism

The arrival of George Saunders’ novel Lincoln in the Bardo as yet another trauma narrative is not surprising. What began as a desire for representation of trauma in media and literature has morphed into an obsession in which trauma is the gold standard. Upon becoming so, trauma is inevitably placed upon a pedestal—the shining object that all other decisions are measured against and based upon. Its placement on this pedestal marks the “sacralization” of trauma. However, Lincoln in the Bardo fills a unique niche in the current portrayals of trauma found in popular media by seeking to minimize its importance …

Genre In Translations Of Sir Gawain And The Green Knight, Madison Schow

Criterion: A Journal of Literary Criticism

A comparison of J.R.R. Tolkien’s translation of Sir Gawain and the Green Knight, published posthumously in 1975, and Simon Armitage’s 2007 translation of Sir Gawain and the Green Knight reveals that a translator’s choices can affect the genre of a work. Tolkien’s foreignizing translation situates Sir Gawain in the tradition of medievalist fantasy and should be read in the context of twentieth century fantasy, the same genre as Tolkien’s original works. Armitage’s domesticating translation places Sir Gawain in the context of twenty-first century fantasy. An examination of the subgenres represented in Sir Gawain and the Green Knight (ghost story, thriller, …

Fragments And Foreignness In Claudia Rankine's Citizen, Cutter Mendenhall

Criterion: A Journal of Literary Criticism

This analysis investigates Claudia Rankine’s redefinition of foreignness as the fragmenting force of microaggressions that splinters the African American identity. This fragmentation has implications that shatter and reconstruct the traditional understanding of the African American self, the source and fallacies of both white and black anger, and what it means to be native to mainstream American society. Ultimately, Rankine asserts that the foreignizing nature of microaggressions is a socially constructed form of oppression. This foreignness breaks the African American identity into easily accessible subhuman caricatures that leave the black identity in a ruptured state of cognitive dissonance. While making coherence …

King Mosiah And The Judgeship, John A. Tvedtnes

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

The immediate situation that prompted Mosiah to institute a system of judges to govern the Nephites was the departure of his four sons. The people asked that Aaron be appointed king, but he and his brothers had gone to the land of Nephi to preach to the Lamanites and had renounced their claims to the monarchy (see Mosiah 29:1–6).
