Ecological Perspectives On Study Abroad For Language Learning, Matthew Thomas Bird Apr 2021

Ecological Perspectives On Study Abroad For Language Learning, Matthew Thomas Bird

Theses and Dissertations

The field of study abroad for language learning has drawn extensively on related fields such as applied linguistics and psychology to conceptualize learners' experiences, which then informs how practitioners go about designing programs for those learners. Research has encouraged practitioners to increase learners' access to the target language (e.g., through speaking partners, content courses), but it has also become clear that while access might be necessary, it does not guarantee learner engagement and growth. This dissertation explores two unique conceptual frameworks for understanding language learners and presents empirical research that demonstrates the kinds of findings that these frameworks can produce. …

Linking Exposure To Political Content On Social Media With Political Polarization: The Mediating Role Of Anger, Audrey Anne Halversen Apr 2021

Linking Exposure To Political Content On Social Media With Political Polarization: The Mediating Role Of Anger, Audrey Anne Halversen

Theses and Dissertations

Previous research has detailed concerns that exposure to both pro- and counter- attitudinal content on social media can result in outcomes of ideological polarization (e.g. Bail et al., 2018; Lu & Lee, 2018). However, further research is needed in order to understand the conditions under which this polarization may take place. To investigate this issue, this study utilizes a sample of 414 social media users in the U.S. to investigate the mediating effects of a) anger toward political opposites and b) anger toward oppositional social media content on the relationships between various types of political content exposure and the outcome …

A Self-Study Of The Shifts In Teacher Educator Knowledge Resulting From The Move From In-Person To Online Instruction, Celina Dulude Lay Apr 2021

A Self-Study Of The Shifts In Teacher Educator Knowledge Resulting From The Move From In-Person To Online Instruction, Celina Dulude Lay

Theses and Dissertations

Given the competing contexts of teacher education, it is important to uncover what teacher educator knowledge concerning curriculum design and development emerges in design, implementation, and instruction during the transition from in-person to online contexts. Yet, there is little research that uncovers teacher educator knowledge in curriculum making generally, and more specifically, how this knowledge is carried forward or changed as teacher educators create and enact online teaching. Because transitions are an important time to uncover tacit and embodied understanding, in this self-study of teacher education practice (S-STEP), I examined my own teacher educator knowledge during planning, teaching, and reflecting …

The Mechanism Of Ptov1 Regulation By 14-3-3, Huwei1 And Sgk2, Pramoda Sahan Kumari Aththota Gamage Apr 2021

The Mechanism Of Ptov1 Regulation By 14-3-3, Huwei1 And Sgk2, Pramoda Sahan Kumari Aththota Gamage

Theses and Dissertations

Prostate tumor overexpressed 1 (PTOV1) is highly expressed in several forms of cancer. High expression of PTOV1 is associated with tumor aggressiveness in several tumor types, including ovarian and breast cancer. Currently, PTOV1 is known to act both as a translational and transcriptional regulator aiding in the expression of prosurvival genes. Although PTOV1 is known to pass in and out of the nucleus in a cell cycle-dependent manner, the regulation of PTOV1 activity is not well understood and here we identify 14-3-3 as a PTOV1 interactor and show that high levels of 14-3-3 expression, like PTOV1, correlate with prostate cancer …

You Do Math Like A Girl: How Women Reason Mathematically Outside Of Formal And School Mathematics Contexts, Katelyn C. Pyfer Apr 2021

You Do Math Like A Girl: How Women Reason Mathematically Outside Of Formal And School Mathematics Contexts, Katelyn C. Pyfer

Theses and Dissertations

Females continue to have negative dispositions towards mathematics even though the performance gap between females and males has all but disappeared. While there are many hypotheses for why these negative dispositions exist among females towards mathematics, this paper explores the possibility that the field of mathematics could favor more masculine ways of reasoning at the exclusion of valid, non-masculine mathematical thought. To research this idea, the day-to-day, non-formal, non-school mathematical activities of two women were identified and analyzed. The analysis uncovered complex mathematical processes among both women that were fundamentally different from the mathematical processes common in the mathematics field. …

Dynamics Of Systems Driven By An External Force, Xue Liu Apr 2021

Dynamics Of Systems Driven By An External Force, Xue Liu

Theses and Dissertations

In this dissertation, we study the complicated dynamics of two classes of systems: Anosov systems driven by an external force and partially hyperbolic systems driven by an external force. For smooth Anosov systems driven by an external force, we first study the random specification property, which is on the approximation of an N−spaced arbitrary long finite random orbit segments within given precision by a random periodic point. We prove that if such system is topological mixing on fibers, then it has the random specification property. Furthermore, we prove that the homeomorphism induced by such a system on the space of …

Spatial Resolution Of Quantitative Electroencephalography And Functional Magnetic Resonance Imaging During Phoneme Discrimination Tasks: An Abbreviated Meta-Analysis, Emily Jean Jacobs Apr 2021

Spatial Resolution Of Quantitative Electroencephalography And Functional Magnetic Resonance Imaging During Phoneme Discrimination Tasks: An Abbreviated Meta-Analysis, Emily Jean Jacobs

Theses and Dissertations

Phonological processing, the ability to recognize and manipulate the sounds of one's native language, is an essential linguistic skill. Deficits in this skill may lead to decreased social, educational, and financial success (Kraus & White-Schwoch, 2019). Additionally, phonological disorders have been shown to be highly variable and individualized (Bellon-Harn & Cradeur-Pampolina, 2016) and therefore difficult to treat effectively. A better understanding of the neural underpinnings of phonological processing, including the underlying skill of phonemic discrimination, could lead to the development of more individualized and effective intervention. Several studies, some using quantitative electroencephalography (qEEG) and others using functional magnetic resonance imaging …

Quantifying Speech Pause Durations In Speakers With Nonfluent And Fluent Aphasia, Brooke K. Thomas Apr 2021

Quantifying Speech Pause Durations In Speakers With Nonfluent And Fluent Aphasia, Brooke K. Thomas

Theses and Dissertations

This study investigates pause duration between and within utterances in the speech of 20 people with different degrees and types of aphasia: 15 with fluent aphasia and five with nonfluent aphasia. It also examines within utterance pause durations as a function of utterance position. Using aphasia speech samples collected in a previous study by Harmon (2018), Praat acoustic analysis software was used to segment words and periods of pause and measure pause duration within and between utterances. The data were analyzed using descriptive statistics, including pause duration mean, standard deviations, and interquartile range. Speech pauses were also categorized by the …

Computing The Rank Of Braids, Justin Meiners Apr 2021

Computing The Rank Of Braids, Justin Meiners

Theses and Dissertations

We describe a method for computing rank (and determining quasipositivity) in the free group using dynamic programming. The algorithm is adapted to computing upper bounds on the rank for braids. We test our method on a table of knots by identifying quasipositive knots and calculating the ribbon genus. We consider the possibility that rank is not theoretically computable and prove some partial results that would classify its computational complexity. We then present a method for effectively brute force searching band presentations of small rank and conjugate length.

Improving Understanding Of Liquid Viscosity Through Experiments And Prediction, Jeremy W. Passey Apr 2021

Improving Understanding Of Liquid Viscosity Through Experiments And Prediction, Jeremy W. Passey

Theses and Dissertations

Liquid viscosity is an important thermophysical property in process design. While liquid viscosity has been studied for over a century, much has been left unexplored. The behavior of liquid viscosity between the melting point and normal boiling point are well established, but yet there is a lack of experimental data – with only 52% of the compounds in the 801 DIPPR database having experimental liquid viscosity data – and inadequate prediction methods. This project was able to measure liquid viscosity for 30 organic compounds to help fill in the gap in the 801 DIPPR database. The measured results also helped …

Effect Of Ported Shroud Casing Treatment Modifications On Operational Range And Limits In A Centrifugal Compressor, Alexander A. Newell Apr 2021

Effect Of Ported Shroud Casing Treatment Modifications On Operational Range And Limits In A Centrifugal Compressor, Alexander A. Newell

Theses and Dissertations

The implementation of a ported shroud casing treatment is often used to extend the operating range of a centrifugal compressor. This work utilizes the STAR-CCM+ CFD package to analyze steady-state, single-passage simulations of a centrifugal compressor with and without a ported shroud to better understand how a ported shroud affects compressor flow physics. Verification and validation of simulations were conducted by comparison of results with a time-accurate full-annulus simulation and experimental data. Four different ported shroud revisions were considered and modeled along the full range of their stable operation, with emphasis placed on the flow limits of choke and stall. …

How Word Characteristics Affect Language-Mediated Eye Movements In Preschoolers With Varying Language Ability, Shelby Nicole Slocum Apr 2021

How Word Characteristics Affect Language-Mediated Eye Movements In Preschoolers With Varying Language Ability, Shelby Nicole Slocum

Theses and Dissertations

Children with lower language abilities, including children with Developmental Language Disorder (DLD) are at risk for persistent reading difficulties. Previous studies have demonstrated that children with lower language abilities display eye movements different from their typically developing peers while hearing nouns in a naturalistic storybook reading context. This study examined how language ability and various lexical characteristics interact with 4- and 5-year- olds' eye movements during a naturalistic storybook reading task. We used eye-tracking technology to measure eye movements of 49 preschoolers with variable language skill. The children looked at storybook pictures on an eye tracking computer while they listened …

Micromechanisms Of Near-Yield Deformation In Bcc Tantalum, Joshua Jr-Syan Tsai Apr 2021

Micromechanisms Of Near-Yield Deformation In Bcc Tantalum, Joshua Jr-Syan Tsai

Theses and Dissertations

New materials, optimized for increased strength, ductility, and other desirable properties, have the potential to improve every aspect of modern living. To achieve these optimums, the necessary technological advancements are impeded mainly by the limits of available material models. Innovations in this field rely on research into the nature of material behavior. While a typical model of material behavior in the region near yield involves the initial linear elastic response, followed by yield and isotropic hardening, this fails to explain various important phenomena that manifest in a range of materials, such as pre-yield nonlinearity, anelasticity, yield point phenomena, hardening stagnation, …

Characterizing Bacterial Resistance And Microstructure-Related Properties Of Carbon-Infiltrated Carbon Nanotube Surface Coatings With Applications In Medical Devices, Stephanie Renee Morco Apr 2021

Characterizing Bacterial Resistance And Microstructure-Related Properties Of Carbon-Infiltrated Carbon Nanotube Surface Coatings With Applications In Medical Devices, Stephanie Renee Morco

Theses and Dissertations

Carbon-infiltrated carbon nanotube (CICNT) forests are carbon nanotube (CNT) forests infiltrated with pyrolytic carbon to increase durability by becoming a solid material. This material can be tuned to maintain the nanotube geometry of a CNT forest and can also be fabricated on a variety of materials and geometries. Additionally, the present work has indicated that CICNT forests may resist bacterial proliferation and biofilm formation. This phenomenon is not due to the CICNT chemistry; it is presumably due to the CICNT nanostructure morphology. Thus, both silicon and stainless steel substrates were used to investigate CICNT's structural resistance to Methicillin-resistant Staphylococcus aureus …

The Relationship Between The Use Of Curriculum Materials And Inquiry-Based Pedagogy, Laura Jo Elzinga Apr 2021

The Relationship Between The Use Of Curriculum Materials And Inquiry-Based Pedagogy, Laura Jo Elzinga

Theses and Dissertations

Little change has resulted from decades of attempts at reforming the teaching of mathematics (Davis et al., 1990). This study involved approximately 43 teachers who had completed an inquiry-based professional development program prior to being provided with a new mathematics curriculum designed to support inquiry-based teaching. It analyzed the relationships between their implementation of the inquiry-based teaching and their use of the curriculum materials. A series of bivariate correlations were run to investigate the relationships between the professional development and aspects related to the implementation of the new curriculum. The factors being so inter-related, it was hypothesized that relationships would …

Experiential Education In The Writing Classroom: Developing Habits For Citizenship, Anika Shumway Apr 2021

Experiential Education In The Writing Classroom: Developing Habits For Citizenship, Anika Shumway

Theses and Dissertations

As political polarity and social divisiveness increase in the United States, more organizations and scholars are calling on institutions of higher education to rise to the occasion and incorporate into their objectives the development of competent citizenship (The National Task Force). Writing classrooms are particularly suited to these kinds of objectives as writing already proposes relationships between rhetor and audience that have ethical dimensions and require mutual honesty, accountability, and respect (Duffy, "The Good Writer"). Additionally, the Framework for Success, a document that has become central to shaping the goals of writing classrooms, articulates habits of mind, like openness and …

From Sea To Waterless Sea: Archipelagic Thought And Reorientation In When The Emperor Was Divine, Summer Weaver Apr 2021

From Sea To Waterless Sea: Archipelagic Thought And Reorientation In When The Emperor Was Divine, Summer Weaver

Theses and Dissertations

Julie Otsuka's novel When the Emperor Was Divine (2002) retells the trauma of the Japanese American imprisonment through the lens of fictional characters taken from their "white house on the wide street in Berkeley not far from the sea" to "the scorched white earth of the desert" (74, 23). The Topaz Internment Camp in Utah's Sevier Desert, where these characters were forcibly relocated, sits on the site of an ancient inland sea, Lake Bonneville, which submerged that barren desert ground some ten thousand years ago. The paleolake serves as a displaced but active character in Otsuka's novel that shapes the …

Going For Gold: Point Of Care Bio-Diagnostics And Gold Nanoparticles Treating Disease, Trevor M. Godfrey Apr 2021

Going For Gold: Point Of Care Bio-Diagnostics And Gold Nanoparticles Treating Disease, Trevor M. Godfrey

Theses and Dissertations

Correct diagnosis of disease is essential in the effort to save and improve lives. Point of care (POC) diagnostics are in-vitro tests that assist in patient diagnosis and can be used at the location of patient care. POC diagnostics are easy to use and provide near-instant readouts allowing medical providers and patients to make rapid decisions about treatment. Increased access to POC testing is especially beneficial to low-income and low resource areas that cannot afford expensive lab testing. The World Health Organization (WHO) has outlined at least 113 diseases for which POC diagnostics are needed. Because of this, developing effective, …

Improving Artistic Workflows For Fluid Simulation Through Adaptive And Editable Fluid Simulation Techniques, Sean A. Flynn Apr 2021

Improving Artistic Workflows For Fluid Simulation Through Adaptive And Editable Fluid Simulation Techniques, Sean A. Flynn

Theses and Dissertations

As the fidelity of computer generated imagery has increased, the need to digitally create convincing natural phenomena like fluids has become fundamental to the entertainment production industry. Because fluids are complex, the underlying physics must be computationally simulated. However, because a strictly physics-based approach is both computationally expensive and difficult to control, it does not lend itself well to the way artists and directors like to work. Directors require control to achieve their specific artistic vision. Furthermore, artistic workflows rely on quick iteration and the ability to apply changes late in the production process. In this dissertation we present novel …

The Dns Bake Sale: Advertising Dns Cookie Support For Ddos Protection, Jacob Davis Apr 2021

The Dns Bake Sale: Advertising Dns Cookie Support For Ddos Protection, Jacob Davis

Theses and Dissertations

The Domain Name System (DNS) has been frequently abused for Distributed Denial of Service (DDoS) attacks and cache poisoning because it relies on the User Datagram Protocol (UDP). Since UDP is connection-less, it is trivial for an attacker to spoof the source of a DNS query or response. DNS Cookies, a protocol standardized in 2016, add pseudo-random values to DNS packets to provide identity management and prevent spoofing attacks. This work finds that 30% of popular authoritative servers and open recursive resolvers fully support cookies and that 10% of recursive clients send cookies. Despite this, DNS cookie use is rarely …

Effects Of Carbon-Infiltrated Carbon Nanotube Growth On The Biocompatibility Of 316l Stainless Steel, Sterling Charles Voss Apr 2021

Effects Of Carbon-Infiltrated Carbon Nanotube Growth On The Biocompatibility Of 316l Stainless Steel, Sterling Charles Voss

Theses and Dissertations

The purpose of this research is to identify the effects of the carbon-infiltrated carbon nanotube (CICNT) growth process on the material properties of 316L stainless steel, particularly those properties which are essential for biocompatibility. Physically altering the micro-topography of a surface can dramatically affect its capacity to support or prevent biofilm growth. Growing CICNTs on biomedical materials is one approach which has demonstrated success at preventing biofilm growth. Unfortunately, the high temperature and carbon-rich gas exposure required for this procedure has proven to have deleterious effects. Rusting has been observed on samples that have been coated with CICNTs and then …
