Informing Field Management Decisions To Enhance Alfalfa Seed Production Using Remote Sensing, Thomas V. Van Der Weide

Boise State University Theses and Dissertations

The development rate of alfalfa seed crop depends on both environmental conditions and management decisions. Crop management decisions, such as determining when to release pollinators to optimize pollination, can be informed by the identification of plant development stages from remote sensing data. I first identify what electromagnetic wavelengths are sensitive to alfalfa plant development stages using hyperspectral data. A Random Forest regression is used to determine the best Vegetation Index (VI) to monitor how much of the plant is covered in flower. The results indicate that Blue, Green, and Near-Infrared are the important electromagnetic wavelengths for the VI. Imagery collected …

Ideological Misalignment In The Discourse(S) Of Higher Education: Comparing University Mission Statements With Texts From Commercial Learning Analytics Providers, Leif A. Nelson

Boise State University Theses and Dissertations

This study analyzes, interprets, and compares texts from different educational discourses. Using the Critical Discourse Analysis method, I reveal how texts from university mission statements and from commercial learning analytics providers communicate and construct different ideologies. To support this analysis, I explore literature strands related to public higher education in America and the emerging field of study and practice called learning analytics. Learning analytics is the administrative, research, and instructional use of large sets of digital data that are associated with and generated by students. The data in question may be generated by incidental online activity, and it may be …

Demand-Side Load Management Using Single-Phase Residential Static Var Compensators, Muhammad Kamran Latif

Boise State University Theses and Dissertations

Distribution systems are going through a structural transformation from being radially-operated simple systems to becoming more complex networks to operate in the presence of the distributed energy resources (DERs) with significant levels of penetration. It is predicted that the share of electricity generation from DERs will keep increasing as the world is moving away from the power generation involving carbon-emission and towards cleaner energy sources such as solar, wind, and biofuels. However, the unstable behavior of the renewables resources presents challenges to the already existing distribution systems. One such problem is when the distribution feeder experience variable power supply due …

Schools are rated as Turnaround, Priority Improvement, Improvement, or Performance status (Colorado Department of Education, 2016b). Schools in Turnaround or Priority Improvement status must move to Improvement or Performance status in less than five years (Colorado Department of Education, 2016e). The focus of the study was on the leadership skills and behaviors of principals in schools …

Mindfulness Intervention To Support School Engagement With At-Risk Students At An Urban Charter High School, Sarah Groark

Dissertations

Every year, more than 500,000 students drop out of school, often after years of growing disinterest and disengagement. As a result, models of school engagement are commonly used as a framework to guide interventions. Unfortunately, some students may experience high levels of dysregulation and poor executive functioning which interfere with their ability to engage in school. The purpose of this study was to investigate whether a school-based mindfulness intervention would support school engagement behaviors with adolescents at an urban charter school. It was hypothesized that mindfulness would support students’ executive functioning in the areas of attention, cognitive flexibility, and emotion …

Increasing Undergraduate Student Engagement In Academics: An Ecological Momentary Intervention, Kerry Douglas Duck

As students enter the university environment, they are presented with various commitments that may or may not impede academic performance. With the issues of student attrition and retention, there is a need to provide further tools for students to use to monitor their performance. As students’ progress to higher level coursework, expectations and time commitments increase, and self-regulation of learning becomes even more important. Researchers may be able to deliver information to help students with self-regulation of learning by leveraging new affordances in technology in students’ daily lives. The purpose of this dissertation was to examine the feasibility and associated …

The Relationship Between State College Readiness Policy And Student Outcomes: A Multilevel Growth Model, Rachel Christeson

Dissertations

This study examined whether policies related to college readiness have a relationship with student outcomes of college-going, student retention rates, and graduation rates for the overall state population as well as the rates specifically for European American and non-European American students. Specifically, a multilevel modeling approach was employed to determine whether significant relationships exist between the presence of state college readiness policies and change in student outcomes over time when controlling for state- and institutional-level factors. Several policies were considered, including: (a) the existence of a college-readiness definition, (b) a requirement for students to take college-prepatory courses in order to …

Liminal Space In Higher Education: Lived Experiences In The Space Between At-Risk Academics And Big-Time Athletics In Division I Power Five, Lainey J. Brottem

Dissertations

The purpose of this qualitative, interpretivist phenomenological study was to understand and provide a transferable, informed, and learned perspective of the daily experience of working in the liminal space between two powerful, ostensibly cooperative but often competing interests: major university undergraduate academics and big-time Division I athletics. Nine learning specialists from Division I Power Five institutions participated in phenomenological interviews. Findings indicated that the phenomenon constituted a liminal space between the opposing forces of academics and athletics, with student-athletes, faculty, colleagues, and coaches having influence on the liminality. Unit directors diminished the sense of liminality while faculty contributed very little …

Using Online Communities To Prepare Teachers To Operate As Transformative Intellectuals, Zachary Morgan Clancy

The Urgent Need For Legal Scholarship On Firearm Policy, Dru Stevenson

Buffalo Law Review

Restrictions on federal funding for research pertaining to firearm policy have stymied academic inquiry by social science and public health researchers for over two decades. As a result, most researchers agree that our public discourse about this urgent issue is woefully under-informed, or even ill-informed, on both sides of the debate. Legal academia, which does not operate under the same grant-writing regime as most other disciplines, can and should help fill this gap in researching and theorizing the unresolved questions related to firearm policy. In fact, theoretical development and clarification from the legal academy is often a necessary antecedent for …

Nonlinear Cointegrating Power Function Regression With Endogeneity, Zhishui Hu, Peter C.B. Phillips, Qiying Wang

Cowles Foundation Discussion Papers

This paper develops an asymptotic theory for nonlinear cointegrating power function regression. The framework extends earlier work on the deterministic trend case and allows for both endogeneity and heteroskedasticity, which makes the models and inferential methods relevant to many empirical economic and financial applications, including predictive regression. Accompanying the asymptotic theory of nonlinear regression, the paper establishes some new results on weak convergence to stochastic integrals that go beyond the usual semi-martingale structure and considerably extend existing limit theory, complementing other recent findings on stochastic integral asymptotics. The paper also provides a general framework for extremum estimation limit theory that …

Fuel Shortages During Hurricanes: Epidemiological Modeling And Optimal Control, Sabique Ul Islam

Doctoral Dissertations and Master's Theses

Hurricanes are powerful agents of destruction with significant socioeconomic impacts. A persistent problem due to the large-scale evacuations during hurricanes in the southeastern United States is the fuel shortages during the evacuation. Fuel shortages often lead to stranded vehicles and exacerbate the evacuation efforts. Computational models can aid in emergency preparedness and help mitigate the impacts of hurricanes. In this thesis, the hurricane fuel shortages are modeled using the Susceptible-Infected-Recovered (SIR) epidemic model. Crowd-sourced data corresponding to Hurricane Irma and Florence are utilized to parametrize the model. An estimation technique based on Unscented Kalman filter (UKF) is employed to evaluate …

Fuel Efficient Control Design And Constrained Motion Analysis For Spacecraft Coulomb Formation In Elliptic Chief Orbits, Muhammad Wasif Memon

Doctoral Dissertations and Master's Theses

The use of Coulomb force has been analyzed in recent years to provide propulsion in space for various applications. Coulomb formation can also be utilized to make close formation spacecraft missions fuel efficient. In this study, the Coulomb formation of two craft is studied in elliptic chief orbits for two formation geometries. The first formation requires both spacecraft to be aligned along the nadir (radial) direction and the second formation requires both spacecraft to maintain a constant separation distance relative to each other while each spacecraft rotates freely on the surface of a sphere with the ratio of the radii …

Numerical Investigation Of Scaling Effects Of A Ramjet-Powered Projectile, Arjun Jaishankar Vedam

Doctoral Dissertations and Master's Theses

Ramjet flowpath miniaturization is a potentially useful technology for integration into munitions to increase range, accuracy, and lethality. The emphasis of this effort is to numerically characterize the performance of a miniature hydrogen-fueled and ethylene-fueled ramjet flowpath during Mach 3 and Mach 3.5 sea-level flight. The effect of geometric scale on ramjet performance is evaluated using high-fidelity RANS CFD models. Sensitivity to nonequilibrium laminar and turbulence-limited chemistry, and transitional turbulence treatments are evaluated. The physical sources of small scale performance limitations are identified for both fuel types. Finally, flowpath integration for small-scale applications is briefly addressed.

In-Situ Measurement Of Resin Shrinkage For Aerospace Components, Samarth Motagi

Doctoral Dissertations and Master's Theses

Resin shrinkage due to chemical changes and thermal gradients plays an important role in the residual stress evolution during composite manufacturing. In this thesis, we develop a new in-situ experimental approach for measuring resin shrinkage during curing with the help of digital image correlation (DIC) instrumented on a specially designed autoclave with borosilicate viewports. The images of the resin sample are captured at regular intervals with the help of DIC to measure the displacement and strains during the curing process. We utilize this method for a comparative analysis of resin shrinkage in two common aerospace epoxies, Epoxy 105 and EPON …

Computational Model For Pedestrian Movement And Infectious Diseases Spread During Air Travel: A Molecular Dynamics-Like Numerical Approach, Pierrot Derjany

Doctoral Dissertations and Master's Theses

There is direct evidence of the transmission of fatal infectious pathogens in large human gatherings. Air transportation is no exception. The mixing of susceptible and infectious individuals in this high-density man-made environment involves pedestrian movement which is generally not taken into account in modeling studies of disease dynamics. This thesis addresses this problem through a multiscale model that combines pedestrian dynamics with stochastic infection spread models. This generic model is applicable to several directly transmitted diseases. Through this multiscale framework, the effectiveness of certain layout and strategies in suppressing the disease spread in highly crowded locations such as airplanes, airports …

A Step Toward Ending Long Airport Security Lines: The Modified Boarding Pass, Joel Lee

Doctoral Dissertations and Master's Theses

Anyone who has traveled by air has most likely experienced long airport security lines. Yet not much is known about its cause because few have considered if passengers have created this problem for themselves. The present study attempts to fill this research gap by suggesting that when passengers are not well-prepared for security screening, they delay the process by making mistakes and not complying with procedures. This lack of preparedness can be attributed to several shortcomings of security signposts. This study proposes the use of a modified boarding pass as an alternative form of signage to help passengers better prepare …

Astrodynamics Of The Next Generation Space Weather Prediction Mission, Mark Herring

Doctoral Dissertations and Master's Theses

Accurate prediction of the solar wind properties, interplanetary magnetic field direction and various space weather phenomena becomes ever more important as our dependence on Earth orbiting spacecraft increases. Different solar wind drivers can lead both to enhancements and losses of relativistic electrons in the outer radiation belts, thus posing a major risk to satellites. To further our understanding of the Sun’s impact on the near Earth space environment, as well as to provide predictive capabilities, a mission placing monitoring satellites in key orbits in the inner Solar System is being proposed. As part of that effort, the possibility of using …
