Animal Representation Of Race In The Princess And The Frog, Tiffany Tyantyan Enoch

Theses and Dissertations

Disney’s 2009 film The Princess and the Frog was created in response to racial criticism. It features the first Black princess as a means of promoting racial equality. This film attempts to positively portray Black characters, who were depicted as violent and lazy in previous animations.

While the film showcases positive themes (e.g., internal beauty and virtuous work) and portrays Black characters in a more positive light than previous films, it still perpetuates the typical racism against people of color. The lack of accurate and equal representation of racial groups in recognizable and famous stories is a persistent issue, and …

The Effects Of Feedback And Prior Knowledge On The Processing Of L2 French, Lesley Erin Smith

Theses and Dissertations

The strand of feedback research within the field of Instructed Second Language Acquisition (ISLA) examines the effects of feedback on the development of second language (L2) knowledge and learning behaviors. While findings often make claims about the relationship between feedback and language processing, much of this research has not measured learners’ concurrent responses to feedback. By and large, the effects of feedback have been inferred from test scores collected after feedback is provided, with few studies analyzing how feedback affects L2 learning behaviors in real time (i.e., during a task). Consequently, we know little about how feedback affects language processing. …

Anthropocene Composition: Teaching Terminal Generations In The Pre-Apocalyptic Classroom, John Michael Purfield

Theses and Dissertations

The Anthropocene is an era characterized by human alteration of the planet at deep geological levels and permeation of anthropogenic damage across all biomes. The primary crisis of this era is climate change, which is understood broadly as the anthropogenic disruption in weather patterns and global temperature averages caused by carbon emissions and other pollutants, as well as extractivism and terraforming (deforestation, monoculture farming, desertification and alterations of waterways, for example). Though popular media tends to frame climate change as a looming but always future problem, it is currently producing casualties, both human and nonhuman. The ongoing great extinction correlates …

Preparing In-Service Elementary Teachers To Support English Language Learners: A Qualitative Case Study Of A Job-Embedded Professional Development Using Tpack, Rachel Theresa Lopez

Theses and Dissertations

Nation-wide, the number of English Language Learners (ELL) in our classrooms continues to increase. Twenty percent of students enrolled in California public schools are ELLs, the highest percentage in the nation. With the continuously growing number of ELLs in our classrooms, our mainstream teachers must be prepared to teach content and meet the unique linguistic needs of these students. At Sotomayor Elementary School in the Central Valley of California, 38% of the students enrolled are ELLs. Despite high numbers of ELLs, the district sees minimal evidence of intentional planning for Designated English Language Development (D-ELD), or instruction specifically targeted to …

Language Ideologies In Transgender Communities In The U.S. South, Archie Crowley

Theses and Dissertations

This dissertation examines how metalinguistic discussions within transgender communities in South Carolina are shaped by experiences, identities, and ideologies related to intersecting social dimensions, specifically, gender, age, race, and regional identity. Based primarily on 20 ethnographic group and individual interviews with 41 transgender individuals living in South Carolina, as well as over 24 months of participant-observation in two trans organizations, the analysis illustrates how trans South Carolinians simultaneously navigated changing norms of community language use, expectations of regional linguistic practices, and mainstream discussions of trans linguistic affirmation. I draw on these sociolinguistic and linguistic anthropological methods to examine how discourses …

Characterization Of The Spatial And Temporal Dynamics Of Floodplain Surface-Water Circulation, Shailesh Cyriel Van Der Steeg

Theses and Dissertations

Floodplains are spatially complex landscapes with a variety of surface features and landforms. These low-relief, low-gradient landscapes may contain extensive networks of well-defined channels and topographically connected depressions, and in some cases, the channels originate as cuts across levees or banks of the main river, referred to as through-bank channels. Corresponding complex patterns of inundation and flow have been detected through remote sensing and in field observations. The complex floodplain flows in response to the passing of flood waves is, however, poorly quantified. This work aims to increase fundamental understanding of floodplain flows and to highlight controls on floodplain wetting, …

Prior to this study, the educator network met monthly for professional learning sessions planned and facilitated by a leader in a non-teacher role. As an action researcher, I restructured the sessions to create an autonomy-supportive environment to foster educators’ leadership skills and promote authentic collaboration. Study participants had autonomy over the planning, aims, content, and facilitation of the networking sessions. A basic qualitative …

Food Insecurity In Youth And Young Adults With Diabetes: Prevalence And Association With Health Behaviors, Lauren Helene Martini

Theses and Dissertations

Given the life-long impact of diabetes(1-5), it is important to engage in behaviors that promote health and wellness to delay or prevent negative health outcomes(3, 6-10). Despite this, youth and young adults with diabetes generally do not adhere to nutritional(11-17) or physical activity(18, 19) recommendations. In households experiencing financial difficulties, especially those who are having difficulty providing sufficient food to all of its members, adhering to recommendations may be even more difficult.

The purpose of this dissertation is to better understand and contextualize food insecurity among youth and young adults (YYA) with youth-onset T1DM and T2DM. The first aim addresses …

Utilizing Deep Learning Methods In The Identification And Synthesis Of Gene Regulations, Jiandong Wang

Theses and Dissertations

Gene expression is the fundamental differentiation and development process of life. Although all cells in an organism have essentially the same DNA, cell types and activities vary due to changes in gene expression. Gene expression can be influenced by many gene regulations. RNA editing contributes to the variety of RNA and proteins by allowing single nucleotide substitution. Reverse transcription can alter the expression status of genes by inducing genetic diversity and polymorphism via novel insertions, deletions, and recombination events. Gene regulation is critical to normal development because it enables cells to respond rapidly to environmental changes. However, identifying gene regulations …

Exploring The Current Training Of Undergraduate Geology Students And Teaching Spatial Skills To Improve Student Outcomes, Ann Marie Klyce

Theses and Dissertations

Spatial skills, which represent the ability to mentally manipulate objects (Schneider & McGrew, 2012; Atit et al., 2020) have been shown to be correlated with entrance, persistence and success in STEM (Shea et al., 2001; Wai et al., 2009). Specifically, these skills have been shown to be necessary to geologists and geoscientists (Hegarty, 2014; Gagnier et al., 2016). While we recognize the importance of these skills, explicit training in them is rarely offered (NRC 2006). Consequently, cognitive scientists and discipline based education researchers have begun concerted efforts to offer training in spatial skills to improve student outcomes (e.g. Uttal et …

Negative Polar Questions And Answers In English And Korean, Keunhyung Park

Theses and Dissertations

The meaning of positive polar questions (PPQs) is relatively straightforward, so the truth conditions of PPQs can be decided easily. In contrast, the meaning of negative polar questions (NPQs) may vary, and simple yes-no answers to NPQs have seemingly unpredictable interpretations. For example, a simple yes answer to a PPQ like ‘Did you have lunch today?’ is easily interpreted as ‘I ate lunch.’ In contrast, the same yes answer to an NPQ like ‘Did you not eat lunch today?’ is not obvious out of context. Why are NPQs more ambiguous than PPQs? Based on our empirical observations of the difference …

Structure Property Investigation And Applications Of Self-Assembled Triphenylamine Bis Urea Macrocycles, Md Faizul Islam

Theses and Dissertations

Porous organic crystals can be advantageous as nanoreactors and in sensing, separations, and storage. The Shimizu group utilizes bifurcated urea hydrogen bonding to direct the assembly small building block into pillars and columns affording functional porous crystals. Recently, our group has examined the incorporation of triphenylamines within the framework of bis-urea macrocycles. These macrocycles assemble into columns that contain the solvent of crystallization bound within the channels. Heating the crystals leads to removal of the solvent and activates the host for guest exchange by single-crystal-to-single[1]crystal transformations. Different electron accepting molecules can be encapsulated inside the pore of the host …

A Semantic Web Approach To Fault Tolerant Autonomous Manufacturing, Fadi El Kalach

Theses and Dissertations
