Learning To "Teacher Think": Using English Education As A Model For Writing Teacher Preparation In The Composition Practicum, Angela Celestine Lankford
Learning To "Teacher Think": Using English Education As A Model For Writing Teacher Preparation In The Composition Practicum, Angela Celestine Lankford
Theses and Dissertations
This study explores the impact of "teacher thinking" exercises in the Composition Practicum as a means of instilling a clearer sense of professional development in graduate instructors. Teacher thinking is a teacher training method that asks the novice instructor to see from the perspective of learners within their writing classrooms. Scholarship on writing teacher preparation programs suggests that English educators regularly employ teacher thinking exercises in the training of secondary school teachers. Teacher thinking has allowed many English education majors to conceptualize and obtain teaching identities by helping them to envision the intricate layers of teaching earlier in their careers. …

Post-Fire Interactions Between Soil Water Repellency, Islands Of Fertility, And Bromus Tectorum Invasibility, Kaitlynn Jane Fernelius
Post-Fire Interactions Between Soil Water Repellency, Islands Of Fertility, And Bromus Tectorum Invasibility, Kaitlynn Jane Fernelius
Theses and Dissertations
An intrinsic link exists between soil moisture and soil nitrogen. Factors that increase or decrease soil moisture can have a profound effect on soil nitrogen cycling, which may have later repercussions in the plant community. Post-fire soil water repellency is one factor that can limit soil moisture acquisition and may indirectly affect nitrogen cycling and weed invasion in woody islands of fertility. Plots centered on burned Juniperus osteosperma trees were either left untreated or treated with a surfactant to ameliorate water repellency. Two years later, soils were excavated from the untreated and treated field plots. In the greenhouse, half of …

The purpose of this thesis was to examine the efficacy of a social communication intervention program designed to increase the accuracy of emotion based word use in three elementary school-aged participants with social communication disorders. The participants took part in a multiple-baseline, 20-session treatment including story enactment, journaling procedures, and supplementary activities. The story enactment portion of the intervention centered on Mercer Mayer's A Boy, A Dog, and A Frog (1967) wordless picture book series. Participants' …
Appropriating Juan Rulfo: The Film Score Of Los Confines As Adaptation, Catherine Mary Day
Appropriating Juan Rulfo: The Film Score Of Los Confines As Adaptation, Catherine Mary Day
Theses and Dissertations
Mitl Valdez's film Los confines (1987) is an adaptation of several works of fiction by the Mexican author Juan Rulfo. The director chose to adapt two short stories ("Talpa" and "¡Diles que no me maten!") and an episode from the author's first novel, Pedro Páramo. Valdez's intent was to "capturar el sentido" of the Jaliscan author or, in other words, to remain faithful to certain elements of his writing while adjusting them to the filmic medium. The musical score of Los confines is the method of appropriation that this study endeavors to investigate, since it shares common themes, metaphors, and …

Translation And Transcription Of A Passage From The Baduem Manuscript: An Eighteenth-Century Portuguese Embassy To China, Annalyn Beus
Theses and Dissertations
This project is a diplomatic transcription and English translation of a passage from an 18-century manuscript that chronicles a remarkable Portuguese embassy to China (Macau). The embassy embarked from Lisbon in February 1752, sailing in a luxuriously outfitted ship (Nossa Senhora da Conceição e Lusitânia Grande), in convoy with a warship (Nossa Senhora das Brotas). The English translation is important because it makes the account accessible to scholars who lack familiarity with Portuguese.This voyage to China is remarkable in light of the long history of maritime loss by the Portuguese. Although the normal projected loss of life on this route …

A Kinetic Study Of Aqueous Calcium Carbonate, Derek Daniel Harris
A Kinetic Study Of Aqueous Calcium Carbonate, Derek Daniel Harris
Theses and Dissertations
Amorphous calcium carbonate (ACC) precipitation is modeled using particle nucleation, growth, and aggregation. The particles are tracked in terms of their radial size and particle density using direct quadrature method of moments (DQMOM). Four separate nucleation models are implemented and are compared to experimental data. In discord with a recent study, it is shown that classical nucleation, coupled with equilibrium chemistry, is in good agreement with experimental data. Novel nucleation mechanisms are presented which fit the experimental data with slightly greater accuracy. Using equilibrium chemistry it is shown that the equilibrium value of ACC is pKeq = 7.74 at 24C, …
Developing Guidelines For Including Mobility-Based Performance Specifications In Highway Construction Contracts, Shawn J. Larson
Developing Guidelines For Including Mobility-Based Performance Specifications In Highway Construction Contracts, Shawn J. Larson
Theses and Dissertations
Construction zones can greatly affect the traffic flow on roadways, especially when lane closures are required. Traditionally, the Utah Department of Transportation (UDOT) has used traffic management specifications that only allow lane closures and road work to be done during predetermined hours or specifications that require a certain number of lanes to be open at all times. Recently, mobility-based work-zone traffic flow maintenance has been considered. This method requires continuous monitoring of mobility-based performance data and a mechanism to send alerts to the contractors when the mobility data does not meet the standards set by the specifications. UDOT recently tested …

Counting Threshold Graphs And Finding Inertia Sets, Christopher Abraham Guzman
Counting Threshold Graphs And Finding Inertia Sets, Christopher Abraham Guzman
Theses and Dissertations
This thesis is separated into two parts: threshold graphs and inertia sets. First we present an algorithmic approach to finding the minimum rank of threshold graphs and then progress to counting the number of threshold graphs with a specific minimum rank. Second, we find an algorithmic and more automated way of determining the inertia set of graphs with seven or fewer vertices using theorems and lemmata found in previous papers. Inertia sets are a relaxation of the inverse eigenvalue problem. Instead of determining all the possible eigenvalues that can be obtained by matrices with a specific zero/nonzero pattern we restrict …
Couple Implicit Rules For Facilitating Disclosure And Relationship Quality With Romantic Relational Aggression As A Mediator, Karl Nathan Meng
Couple Implicit Rules For Facilitating Disclosure And Relationship Quality With Romantic Relational Aggression As A Mediator, Karl Nathan Meng
Theses and Dissertations
This study examines the association between couple implicit rules related to facilitating disclosure and marital quality with husband and wife romantic relational aggression as potential mediators. Couples (N-353 couples) who participated in the Flourishing Families Project, reported on their use of couple implicit rules related to disclosure. Results indicated that implicit rules for couple disclosure were positively related to marital quality for both husbands and wives. Those couples who reported more use of implicit rules related to disclosure were also likely to use less romantic relational aggression. In turn, both husband and wife romantic relational aggression was negatively related to …
Grammar In The Composition Classroom: Rewriting The Tradition, Debra Lynn Reece
Grammar In The Composition Classroom: Rewriting The Tradition, Debra Lynn Reece
Theses and Dissertations
In the last 50 years, the trend in the field of composition pedagogy has turned away from traditional grammar instruction, condemning pedagogical practices that focus on preventing and remediating error. In the early 1960s, Richard Braddock, Richard Lloyd-Jones, and Lowell Schoer invoked the death sentence on traditional grammar instruction: "The teaching of formal grammar has a negligible or, because it usually displaces some instruction and practice in actual composition, even a harmful effect on the improvement of writing" (37-38). Having been enlightened by this scholarship, the field refocused instruction to emphasize elements like writing process, collaboration, modeling, and prewriting, pushing …

Civitas: A Game-Based Approach To Ap Art History, Anna Davis
Theses and Dissertations
To increase student engagement as well as cover the content of Ancient Rome, the author developed a game named Civitas for an AP Art History course. The question driving this research project was, "Will incorporating a game into this Ancient Rome unit increase engagement without sacrificing the academic integrity of the class?" Research about engagement as well as others' success incorporating games into the classroom was examined to determine the benefits and difficulties. Much of the work for this unit came before any teaching occurred: designing all aspects of the game as well as carefully determining how it would contribute …
Liquid Core Waveguide Sensors With Single And Multi-Spot Excitation, Lynnell Uilani Wai Yee Zempoaltecatl
Liquid Core Waveguide Sensors With Single And Multi-Spot Excitation, Lynnell Uilani Wai Yee Zempoaltecatl
Theses and Dissertations
Using silicon based microfabrication and materials, a photonic platform, capable of single bioparticle analysis, has been developed. This platform combines liquid and hollow core waveguides on the micron-scale (5 µm x 12 µm) to isolate femtoliter sized sample volumes. Fluorescence excitation and signals in the visible range are directed into and out of the sample volume at an orthogonal angle to maximize signal-to-noise. In order to guide light in a low-index material antiresonant reflecting optical waveguides (ARROWs) were incorporated into the platform. This thesis reveals the development path of these structures over several device generations including innovations in material, geometries, …
Automatic Modulation Recognition For Aeronautical Telemetry, Jacob William Frogget
Automatic Modulation Recognition For Aeronautical Telemetry, Jacob William Frogget
Theses and Dissertations
This these explores automatic modulation recognition as applied to PCM/FM, SOQPSK- TG and ARTM CPM. It found that the likelihood based approach is intractable. The statistical features of the amplitude, phase and frequency are ineffective at distinguishing these modulation types. A method based on the phase changes between symbols is developed and shows that as long as symbol timing is established, this method can effectively distinguish PCM/FM, SOQPSK-TG and ARTM CPM for signal-to-noise ratios above 30 dB. Another method, the Bianchi-Loubaton- Sirven technique, was able to distinguish PCM/FM and SOQPSK-TG but was unable to distinguish ARTM CPM. A happy byproduct …
Delamination Detection In Concrete Using Disposable Impactors For Excitation, Anjali Narendra Patil
Delamination Detection In Concrete Using Disposable Impactors For Excitation, Anjali Narendra Patil
Theses and Dissertations
Delaminations in concrete bridge decks result primarily from corrosion of the reinforcing bars (or rebar). This corrosion leads to volumetric expansion of the rebar. When the rebar expands, concrete cracks, and there is a localized separation of the concrete cover from the underlying concrete. Impact-echo testing is an effective technique to map delaminations on concrete bridge decks. However, mapping speed is limited by necessary retrieval of the impactor for traditional tests. To achieve higher scanning speeds, it is advantageous to use both a non-contact measurement (air-coupled impact-echo) and disposable-impactor excitation. Disposable impactors have the potential advantage of achieving greater deck …
How Social Media Affect The Social Identity Of Mexican Americans, Kaitlin Eve Felsted
How Social Media Affect The Social Identity Of Mexican Americans, Kaitlin Eve Felsted
Theses and Dissertations
This is a thesis conducted qualitatively using the Grounded Theory approach where in-depth interviews were conducted with 12 legal Mexican Americans in order to understand how social media affect Mexican Americans' social identity. This effect was understood by discovering the relationships between social identity theory and integration. Results showed that Mexican Americans felt that social media helped them with their English skills and connected them to their friends and family in Mexico. Mexican Americans were able to use social media to connect to their in-group community, and Mexican American community leaders were able to connect Mexicans to their in-group within …
Certain Agave Species Exhibit The Capability To Be Moderately Productive Under Conditions Of High Salt And Drought Stress, Steven J. Bergsten
Certain Agave Species Exhibit The Capability To Be Moderately Productive Under Conditions Of High Salt And Drought Stress, Steven J. Bergsten
Theses and Dissertations
Water availability and arable lands are increasingly limiting resources in many parts of the U.S., particularly in semi-arid and arid regions. As a means of addressing food and fuel demands associated with burgeoning population growth, highly productive and water-use efficient crops need to be identified. One potential crop, Agave, merits consideration and evaluation due to its putative capability to provide sustenance and energy despite growing in water-limited regions and on marginal soils. However, little is known regarding the productivity these succulent plants will have under growing conditions of the Southwest, where high concentrated saline soils are abundant, and water is …
An Experimental Analysis Of The Weighted Sum Of Spatial Gradients Minimization Quantity In Active Structural Acoustic Control Of Vibrating Plates, Daniel R. Hendricks
An Experimental Analysis Of The Weighted Sum Of Spatial Gradients Minimization Quantity In Active Structural Acoustic Control Of Vibrating Plates, Daniel R. Hendricks
Theses and Dissertations
Active Structural Acoustic Control (ASAC) is a subcategory of the more widely known field of Active Noise control (ANC). ASAC is different from traditional ANC methods because it seeks to attenuate noise by altering the noise producing structure instead of altering the acoustic waves traveling through the air. The greatest challenge currently facing ASAC researchers is that a suitable parameter has not yet been discovered which can be easily implemented as the minimization quantity in the control algorithms. Many parameters have been tried but none effectively attenuate the sound radiation in a way that can be easily implemented. A new …
Effect Of Full-Annular Pressure Pulses On Axial Turbine Performance, Mark H. Fernelius
Effect Of Full-Annular Pressure Pulses On Axial Turbine Performance, Mark H. Fernelius
Theses and Dissertations
Pulse detonation engines show potential to increase the efficiency of conventional gas turbine engines if used in place of the steady combustor. However, since the interaction of pressure pulses with the turbine is not yet well understood, a rig was built to compare steady flow with pulsing flow. Compressed air is used in place of combustion gases and pressure pulses are created by rotating a ball valve with a motor. This work accomplishes two main objectives that are different from previous research in this area. First, steady flow through an axial turbine is compared with full annular pulsed flow closely …
A Teacher's Guide To Academic Reading: Focusing On The Academic Reading Demands Of Esl Learners, Rebecca Jean Stone
A Teacher's Guide To Academic Reading: Focusing On The Academic Reading Demands Of Esl Learners, Rebecca Jean Stone
Theses and Dissertations
With over 765,000 English-as-a-second-language (ESL) students studying in the United States, a greater understanding of the academic requirements and demands these students face while studying in the US is needed. Some of the biggest challenges they face include the amount of reading required and the various tasks employed with academic reading. University reading tasks require more than an understanding of the text. These tasks place a strong emphasis on text comprehension, summary, synthesis, and critical analysis. This is problematic as students, especially ESL learners, lack experience with academic tasks, and many additionally struggle with low metacognitive awareness, limited or low …
