Examining Self-Regulation Of Learning Among Community College Students In Developmental Mathematics Courses, Katrina M. Eberhart

Theses and Dissertations

The ability to self-regulate one’s learning is crucial to the success of all college students, but is particularly important to those who are considered to be underprepared; it puts students on a path towards successful course completion, subsequent course enrollment, and eventual graduation from a postsecondary institution. Those enrolled in remedial coursework are a large portion of students labeled as underprepared. Remedial education is a contentious topic in higher education. Thus, it is critical to investigate the use of classroom strategies to foster a self-regulated environment to support student success in these early classes and move onto the classes needed …

Enhancing Liquid And Gas Separation With Activated Carbon Mixed-Matrix Membranes, Jeremy Lewis

Theses and Dissertations

Mixed matrix membranes are one class of membrane material that are an especially promising separation media. By adding a particle phase to a matrix phase, multiple mechanistic pathways become available that are not present in pristine organic or inorganic membranes. These pathways can be exploited to better enhance separation performance for a variety of applications.

This research has focused on a specific mixed matrix membrane, which contains bio-derived activated carbon particles in a polysulfone matrix. In proper selection of activating agent, this research has shown that the surface functional groups of the activated carbon are highly influenced. This can lead …

Examining The Perceptions Of Bullying Between Certified And Non-Certified School Personnel, Shanna Morlock

Theses and Dissertations

Bullying has been a widely researched topic. However, many areas are yet to be researched in regards to school personnels’ perceptions. This dissertation was focused around several of these missing research areas, as well as included non-certified staff. Non-certified staff have been left out of the vast majority of studies involving school personnel and bullying. That, or their perceptions have not been explored as a separate group of school personnel. This is problematic as non-certified staff are often part of supervisory roles in settings where bullying often occurs. This study addressed differences among school personnel perceptions in regards to bullying …

A deep learning-based method Convolutional Neural Network (CNN) and Support Vector Machine (SVM) for earthquake prediction is proposed. Large-magnitude earthquakes triggered by earthquakes can kill thousands of people and cause millions of dollars worth of economic losses. The accurate prediction of large-magnitude earthquakes is a worldwide problem.

In recent years, deep learning technology that can automatically extract features from mass data has been applied in image recognition, natural language processing, object recognition, etc., with great success. We explore to apply deep learning technology to earthquake prediction, we propose a deep learning method for continuous earthquake prediction using historical seismic events. …

Movement Ecology Of A Cryptic Ambush Predator: Integrating Radio Telemetry And Tri-Axial Accelerometry To Evaluate Spatial Strategies And Activity Patterns By Western Diamond-Backed Rattlesnakes (Crotalus Atrox), Dominic L. Desantis

Open Access Theses & Dissertations

An animal's decision to move from one location to another within its environment is determined by a complex blend of internal and external factors. Teasing apart the relative roles of specific variables in this web of interacting mechanisms has been a long-standing challenge in animal movement ecology. Historically, this problem was viewed as a sort of black box for which a myriad of methodological limitations precluded rigorous study. Recently, a diversity of animal-borne transmitters and dataloggers (i.e., bio-loggers) have circumvented many of these traditional limitations and transformed field studies of animal movement, behavior, and physiology - in some cases, allowing …

Novel Maximum Entrophy Method For The Average Survival Time Differences Between Two Groups, Joscelyne Guzman - Gonzalez

Open Access Theses & Dissertations

We suggest a Maximum Likelihood estimator for the Average Survival Time Difference between two groups, based on the extra time in which should be added to one group to produce the maximum entropy of the result. The estimator is calculated only from time to event data, does not assume hazard proportionality and provides directly the magnitude of the clinical differences between the groups. Our Monte Carlo simulations show that, even at low sample numbers the estimator is a reliable predictor for the clinical differences between the groups, and therefore can be used to estimate from preliminary data whether or not …

Interactions Of Bacterial Communities With Hydrous Sulfate Minerals In Water-Restricted Gypsic Environments: A Case Study Based In The White Sands National Monument, Brandon Nicholas Lajoie

Open Access Theses & Dissertations

Microbial communities have been commonly found to survive and thrive in arid to hyper-arid gypsic environments that are considered hostile to most other forms of life. The mechanisms through which microbes have conquered these harsh environments remain poorly understood. Here I hypothesize that the microbial communities in water-restricted gypsic settings could benefit in terms of energy and water sources via their interactions with the abundant hydrous sulfate minerals [i.e., gypsum (CaSO4·2H2O)] that build up these niches. Gypsum is of high bio-relevance because its sulfate component may be used as electron acceptor by sulfate-reducing bacteria and the crystallization water may be …

The Language Content Of Computer-Mediated Versus Face-To-Face Motivational-Type Interviews, Karla Deyanira Llanes

Open Access Theses & Dissertations

Motivational Interviewing (MI) is an extensively used technique to facilitate behavior change by increasing a person's own motivation and commitment toward change. Recently, several innovative and effective ways to conduct motivational interviews have emerged. However, one potential option has not been investigated: the utility of conducting a motivational interview via computer. The current study begins to address this gap in knowledge by comparing the language content of computer-mediated motivational-type interviews and face-to-face motivational-type interviews. The motivational-type interviews were conducted with young adults who reported ambivalence about their level of recreational marijuana use. Specifically, non-marijuana users, occasional marijuana users, and frequent …

Study Of D-Electron Systems With Fermi-Lowdin Orbital Self-Interaction Correction, Prakash Mishra

Open Access Theses & Dissertations

Density Functional Theory (DFT) is one of the very popular and versatile methods for calculations to study electronic structure, and the accuracy of DFT depends on the approximation used in the exchange-correlation functional. One of the known problems with the approximation is that the widely used density functional approximations (DFA) suffer self-interaction errors. Systems with d-electrons such as transition metal oxides often show deviation of DFT predicted behavior from experimental result. SIE tends to unphysically lower the energies of fractionally occupied state which leads to deviation from piece-wise linear behavior of total energy between two integer occupations. This leads to …

Cross-Language Activation And Integration Of Concepts In Text Passages, Karly Meillyn Schleicher

Open Access Theses & Dissertations

Learning from text requires the ability to efficiently activate and retrieve relevant concepts from long-term memory and connect these with new information that is being presented in the text. It is assumed that memory representations built from text can be influenced by both surface level information (i.e., word forms), or deeper, conceptual level information. The goal of the present study was to investigate the role of surface level features (i.e., language) influence memory representations developed from text. By recruiting Spanish-English bilinguals, the present study investigated how surface level features from a reader's two lexicons influences the activation and integration of …

Recent Changes In The Zooplankton Communities Of Arctic Tundra Ponds In Response To Warmer Temperatures And Nutrient Enrichment, Mariana Vargas Medrano

Open Access Theses & Dissertations

Warming is altering Arctic freshwater ecosystems, enriching the water column, increasing primary productivity and shifting the composition, dominance and the timing of emergence and reproduction of zooplankton communities. Historic data from arctic tundra ponds near UtqiaÄ¡vik, AK have given us valuable insight into changes that have occurred in recent times. A change of dominance from cyclopoid copepods to Daphnia middendorffiana has occurred over a 40 year period. Daphnia are more common, abundant and larger, which may be explained by increased primary productivity stimulated by nutrient release from permafrost thaw. Copepods and fairy shrimp emerged earlier from the overwintering states, which …

Stem rust (caused by Puccinia graminis f. sp. tritici) is a major disease of wheat. To understand the genetic basis of stem rust resistance in Nebraska winter wheat, a set of 330 genotypes representing two nurseries (DUP2015 and TRP2015) were evaluated for resistance to a Nebraska stem rust race (QFCSC) in two replications. The TRP2015 nursery was also evaluated for its resistance to an additional 13 stem rust races. The analysis of variance revealed significant variation among genotypes in both populations for stem rust resistance. Nine stem rust genes, Sr6, Sr31, Sr1RS^Amigo, Sr24, Sr36 …

Cover Crops And Corn Residue Removal: Impacts On Soil Hydraulic Properties And Their Relationships With Carbon, Michael Sindelar, Humberto Blanco-Canqui, Virginia L. Jin, Richard B. Ferguson

Department of Agronomy and Horticulture: Faculty Publications

Large-scale crop residue removal may negatively affect soil water dynamics. Integrating cover crop (CC) with crop residue management can be a strategy to offset potential adverse effects of residue removal. We studied: (i) the impact of corn (Zea mays L.) residue removal (56%) with and without the use of winter rye (Secale cereale L.) CC on soil hydraulic properties, (ii) whether CC would ameliorate residue removal effects on hydraulic properties, and (iii) relationships of hydraulic properties with soil organic C (SOC) and other properties under irrigated no-till continuous corn on a silt loam in south central Nebraska after …

Estimating Percentages Of Fusarium-Damaged Kernels In Hard Wheat By Near-Infrared Hyperspectral Imaging, Stephen R. Delwiche, I. Torres Rodriguez, S. R. Rausch, R. A. Graybosch

Department of Agronomy and Horticulture: Faculty Publications

Fusarium head blight (FHB) is among the most common fungal diseases affecting wheat, resulting in decreased yield, low-density kernels, and production of the mycotoxin deoxynivalenol, a compound toxic to humans and livestock. Human visual analysis of representative wheat samples has been the traditional method for FHB assessment in both official inspection and plant breeding operations. While not requiring specialized equipment, visual analysis is dependent on a trained and consistent workforce, such that in the absence of these aspects, biases may arise among inspectors and evaluation dates. This research was intended to avoid such pitfalls by using longer wavelength radiation than …

Polymerization Of Bromoundecylacrylate And Alkylating Methylimidazole, Shuziao Li

Master's Theses and Doctoral Dissertations

Polymerized ionic liquids (PIL) generally are solids, but a few examples have been reported that also exhibit liquidity in the neighborhood of room temperature called liquid polymerized ionic liquids (LPIL). The development of a platform suitable for exploring LPIL properties based on the monomer 11-bromoundecylacrylate (AcC11Br) was reported. Poly(AcC11Br) is itself a liquid polymer and can be easily used to alkylate 1-methylimidazole to produce poly(AcC11C1ImBr-co- AcC11Br). Various reaction conditions were explored to examine how extensively 1- methylimidazole can be attached to this polymer, and the extent of alkylation is determined quantitatively by silver ion potentiometry. These polymers retain liquidity at …

This research looks at women in a politically and religiously conservative area in the central Midwest. The research is meant to be exploratory in nature in order to grasp an understanding of how not only educational and career aspirations affect attitudes toward marriage but also at how leisure activities and the sexual revolution play a major role in the desire to delay marriage. Interviews were conducted to expose women’s attitudes, opinions, choices, …

Assessing Student Success: Predictive Validity Of The Act Science Subscore, Meāgan Nichole Treadway

Master's Theses and Doctoral Dissertations

The number of applications to postsecondary institutions continues to increase year over year, and in most cases, the number of applications exceeds the number of students admitted. The use of standardized tests continues to grow to help in these admissions decisions. Due to both high usage rates and the changing demographics of our nation’s student population, the study of test bias is still a relevant conversation today. Aside from larger issues of equity and access, particularly in STEM courses, this has implications for leaders in higher education because universities have a stake in ensuring students are academically fit for the …

Designing A Modified Zeeman Slower For The Paschen-Back Magnetic Regime, Leo Michael Nofs

Master's Theses and Doctoral Dissertations

Controlled study of high-density plasmas, such as those found in fusion reactions and stars, is difficult due to their highly-magnetized environments. A specialized high magnetic field (High-B) trap was developed at the University of Michigan in Georg Raithel's research group to study such highly magnetized, high density plasmas using rubidium atoms. By replacing the atom source with a Zeeman slower, a well-studied device to slow and cool atoms, the atom flux could be increased by a factor more than 1000, leading to higher High-B plasma densities. The goal of this project is to design a Zeeman slower that differs from …

Assessment Of Mudpuppy (Necturus Maculosus) Presence Along The St. Clair-Detroit River System Using Environmental Dna And Occupancy Modeling, Jenny L. Sutherland

Master's Theses and Doctoral Dissertations

The mudpuppy (Necturus maculosus) is cryptic, fully aquatic salamander within the Great Lakes region. Once abundant throughout its range, evidence now suggests that there have been declines due to habitat loss and lampricide use. Information on the status of mudpuppies along the St. Clair-Detroit River System (SCDRS) is lacking, and since they are important bio-indicators, they could be a gauge for restoration success. Environmental DNA (eDNA) and occupancy modeling were used to determine best detection practices for this cryptic species. Mudpuppy eDNA was detected at all known mudpuppy sites with the addition of one site. Occupancy was highest at shoreline …

Synthesis And Study Of The Micellization Behavior Of A Dual Temperature- And Ph-Responsive Paa-B-Pnipam Block Copolymer, Ehsan Zarshenas Moghadam

Master's Theses and Doctoral Dissertations

Amphiphilic diblock copolymers are composed of hydrophilic and hydrophobic regions. When they are exposed to water, the hydrophobic blocks aggregate to form a hydrophobic core surrounded by hydrophilic regions outside to give a core-shell micelle. These micelles have many potential applications, such as a drug delivery system, surfactants, or nanoreactor. Many studies have been done to optimize the performance of these copolymers. In this thesis work, nine dual temperature- and pH-responsive poly(acrylic acid-block-N-isopropylacrylamide) (PAA-b-PNIPAM) diblock copolymers with different relative chain lengths of the hydrophobic and hydrophilic blocks were synthesized by reversible addition fragmentation chain transfer polymerization. The preliminary results showed …
