We completed a literature review and participatory mixed-method evaluation of projects in Saving Brains®, Grand Challenges Canada® funded ECD portfolio across 23 low- and middle-income countries (LMIC). Using an adapted programme cycle, findings from evaluation related to partnerships and leadership, situational analyses, and design for scaling ECD were considered. 39 projects (5 'Transition to Scale' and 34 'Seed') were evaluated. 63% were delivered through health and 84% focused on …

A Gis-Based Synthesis Of Relict Shorelines In Pennsular Florida, Justin O. Hardin

Ocean Engineering and Marine Sciences Student Publications

A literature review as well as a consultation with a geomorphologist, Dr. Christopher P. Williams, at the Florida Geological Survey (FGS) were both performed in order to understand the state of knowledge on relict shorelines in peninsular Florida. This knowledge was compiled into a map, Figure 1, that shows the locations and relative ages of geologically confirmed relict shorelines in the Florida peninsula. A number of additional required areas of research in order to “complete” the map are then discussed. The project highlights both the rapidity of Florida’s Pliocene-Pleistocene coastal evolution and the relatively high amount of incompleteness still present …

Evolving Narratives About College: Immigrant Community College Students’ Perceptions Of The Four-Year Degree In The Great Plains, Moises Padilla, Justin Chase Brown, Elvira Abrica

Department of Educational Administration: Faculty Publications

A significant percentage of the enrollment growth in higher education can be attributed to the recruitment of more diverse students, including those from immigrant households. Although research on immigrant students is growing in light of changing U.S. demographic shifts, this literature is inchoate. This paper examines evolving perspectives of the value of a four-year degree among immigrants and children of immigrants. Thus, in this paper article we synthesize current dominant narratives of immigrant students about the utility and viability of a four-year degree (and the changing impact on community college enrollment) and how they have shifted over time. We observe …

A Deep Learning Approach To Detect Diabetic Retinopathy In Fundus Images., Winston R. Furtado

Electronic Theses and Dissertations

Background: Diabetic retinopathy is a disease caused due by complications of diabetes mellitus which can lead to blindness. About 33% of the US population with diabetes also show symptoms for diabetes retinopathy. If not treated, diabetic retinopathy worsens over time by progressing through two main pathological stages of non-proliferative and proliferative and four clinical stages. While the diagnostic accuracy of detecting diabetic retinopathy through machine learning have shown to be successful for OCT images, the accuracy of ultra-widefield fundus images have yet to be fully reported. This paper describes a method to non-invasively detect and diagnose diabetic retinopathy from ultra-widefield …

Experimental Investigation Of The Manufacture Of Tunable Graphene Oxide Filter Membranes Using Intense Pulse Light, Joshua H Kotter

Electronic Theses and Dissertations

Reduced graphene oxide is a thin, strong, and inexpensive material with a channel and pore structure that make it a promising candidate for a filtration material. Reduced graphene oxide has been produced and tested in the laboratory, but a lack of scalable manufacturing techniques have limited its commercial use.

This thesis has shown that graphene oxide can be rapidly manufactured with an industrially scalable flash reduction process. The flash reduction process uses 0.58 millisecond pulses from a xenon lamp to reduce the graphene oxide film in less than a minute. Results for partially reduced graphene oxide membranes tuned by the …

Fiber-Reinforced Polymer Bridge Girders For Extremely Aggressive Environments, Abdellah Emad Azeez

Doctoral Dissertations and Master's Theses

In 2012, the federal government estimated that $17.5 billion was spent on inspection, rehabilitation, maintenance, and replacement of the nation’s bridges. While the average lifespan of steel and reinforced concrete bridges is 50 years, certain bridges subjected to extremely aggressive marine environments may not reach this desired target. This research paper investigates using fiber-reinforced polymer (FRP) materials as primary bridge girders in medium span bridges (30 ft. to 75 ft.). The goal of this research is to identify the most efficient and cost-effective alternative for these corrosion-resistant materials and potentially extend the lifespan of these bridges up to 75 years. …

Uncover The Power Of Multipath : Detecting Nlos Drones Using Low-Cost Wifi Devices, Ashok Vardhan Raja

In recent years, consumer UAV technology has seen considerable advances. Consumer UAVs have become an ideal vector for privacy invasions due to their affordability, size, maneuverability, and their ability to stream live high-quality video. There is considerable proliferation of drones in both civil and military domains. Hence it is critical to detect invading unmanned aerial vehicles (UAVs) or drones in a timely manner for both security and safeguarding privacy. Currently available solutions like active radar, video or acoustic sensors are very expensive (especially for individuals) and have considerable constraints (e.g., requiring visual line of sight).

Recent research on drone detection …

Planar Ion Probe For Low-Latitude Ionosphere/Thermosphere Enhancements In Density Cubesat Mission, Liam Owen Gunter

Doctoral Dissertations and Master's Theses

One of the crucial measurements for characterizing any space weather event is absolute plasma density and plasma density fluctuations, both spatially and temporally. Langmuir probes are the oldest and most proven instruments for these in-situ measurements. This thesis enumerates the development of a miniaturized low-noise Langmuir probe intended for a dual CubeSat mission to study equatorial temperature and wind anomaly in the Earth’s ionosphere.

The Langmuir probe instrument developed is of a planar geometry and fix biased in the ion saturation region, i.e. negative w.r.t. spacecraft chassis. Operating the Langmuir probe in the ion saturation region avoids excessive spacecraft charging …

Scale Interactions Within A Perturbed Plane Wall Jet, Shibani Bhatt

Doctoral Dissertations and Master's Theses

The current work focuses on exploiting this behavior to manipulate wall turbulence by targeting the large-scales of the flow. In wall turbulence the large-scales of the flow interact with the smaller scales in a non-linear manner including through a process of amplitude and frequency modulation. A plane wall jet (PWJ) is chosen as the model flow field for this work as its unique geometry allows for the controlled introduction of large-scale perturbations through acoustic forcing. The corresponding interactions because of forcing are characterized using single hot-wire measurements. The nearwall response of the PWJ over a range of large-scale forcing showed …

Geometric Effects Of Thermal Barrier Coating Damage On Turbine Blade Temperatures, Shane Colon

Doctoral Dissertations and Master's Theses

Thermal barrier coatings (TBC) found on turbine blades are a key element in the performance and reliability of modern gas turbines. During the life of the turbine components, the TBC surface may be damaged due to manufacturing imperfections, handling damage, service spalling, or service impact damage, producing chips in the coating. While a chip in the TBC coating is expected to cause an increase in airfoil temperature, it is unknown to what degree the blade will be affected and what parameters of the chip shape affect this result. The goal of this preliminary study is to identify the major driving …

Global Estimation Methodology For Wave Adaptation Modular Vessel Dynamics Using A Genetic Algorithm, Marco Alan Schoener

Doctoral Dissertations and Master's Theses

Determining parameters for a system model for marine vessels becomes more difficult as the model is made more complex. Work has been done to determine the equations of motion, but not to fully define how to estimate all of the system parameters. This work utilizes a global optimization methodology for estimating the system parameters using a genetic algorithm. The optimizer uses training data sets created from a set of ship maneuvering standards to minimize the error in the 3 degree-of-freedom equations of motion. The model has been optimized using a “No Surge-Yaw” model (minimal surge coupling) and a “Full” model …

Characterization Of Air Dissolution And Reappearance Under Pressure In Cement Pastes By Means Of Rheology, Daniel Galvez-Moreno, Dimitri Feys, Kyle Riding

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Concrete pumping is the most used technique to transfer concrete from the mixer truck to the formwork. Numerous studies have been performed on the flow behavior of concrete in pipes, as well as the consequences of pumping on fluid and hardened concrete properties. One of the negative consequences of pumping concrete is a decrease in freeze-thaw resistance. This is caused by a decrease in air content and an increase in air bubble size, due to dissolution and reappearance of air and air bubble coalescence under pressure. This paper investigates the capability of rheology to understand air dissolution and reappearance in …

Harsh Parenting In Military Versus Civilian Families: Does Military Culture Moderate The Influence Of Socioeconomic Status And Race?, Tiren Antinette Parker

Psychology Theses & Dissertations

Harsh parenting techniques such as yelling and spanking are commonly used in the United States to discipline children, despite the evidence that harsh parenting has a negative sequalae for children that can persistent into adulthood. Socioeconomic status (SES) and race/ethnicity have been identified as two key determinants of harsh parenting. The stressors associated with military service and parenting within military culture place families at increased risk for harsh parenting and child maltreatment. Having a better understanding of how sociodemographic factors influence parenting behaviors within the military culture may help to develop psychoeducational and parenting programs as well as therapeutic interventions …

Chemistry & Biochemistry Theses & Dissertations

A SERS device was made using a dual-nanostructured surface comprised of silver nanoparticle and silver nanowires. The ability of each nanostructure to produce a uniform surface was characterized and the surface-enhanced Raman scattering (SERS) response of the resulting surfaces were examined using the reporter molecule 4-aminothiolphenol (ATP) and a 638 nm excitation laser.

A synthetic method was developed to produce silver nanowires with lengths of ~20 μm and diameters of ~100 nm with a narrow size distribution. The method utilized a simple, one-pot synthesis that is amenable to large-scale production. A selective precipitation method was used to the isolate the …

Comparing Higher Order Value Differences By Religious And Spiritual Association And Implications For Counseling: An Exploratory Study, Gregory C. Lemich

Counseling & Human Services Theses & Dissertations

The spiritual but not religious (SBNR) population in the U.S. has grown into a significant minority demographic (27%; Lipka & Gecewicz, 2017). Despite this emergence, scant literature has addressed this population and how it differs in values from others, specifically, how SBNR groups differ from those who identify as spiritual and religious (SAR), religious but not spiritual (RBNS), and not spiritual or religious (NSOR). To help this deficiency, this dissertation study explored the intersection of spirituality, religiosity, spiritual and religious categories (SRC; i.e. SAR, SBNR, RBNS, NSOR), and the theory of basic human values (Schwartz, 1992, 1994; Schwartz et al., …

Building Entrepreneurial Self-Efficacy (Ese): How Undergraduate Students Make Meaning Of Their Entrepreneurial Experiences, Amy Kurfist

Educational Leadership & Workforce Development Theses & Dissertations

This qualitative, interview-based research study explores how undergraduate students at a single research university make meaning of their experiences in curricular and co-curricular university entrepreneurship programming. The study focuses on the developmental relationship between entrepreneurship education and feelings of entrepreneurial self-efficacy (ESE) and how feelings of ESE relate to future entrepreneurial intentions. I explore three of Bandura’s (1977) predictors of self-efficacy: mastery experiences, vicarious experiences, and social persuasion interwoven with the six dimensions of ESE developed by De Noble, Jung, and Ehrlich (1999) to determine how undergraduate students make meaning of their entrepreneurial experiences.

Through the analysis of data collected …

Sponge Community Biocomplexity, Competition, And Functional Significance In Hard-Bottom Habitats Of The Florida Keys, Fl (Usa), Marla Maxine Valentine

Biological Sciences Theses & Dissertations

Sponges can have powerful effects on ecosystem processes in shallow, tropical marine ecosystems and are an integral component of the bentho-pelagic cycle of nutrients, via filtering of dissolved and particulate organic matter from the water column. The diversity of marine communities is thought to play a determining role in intensity of ecosystem processes; thus the loss of taxa alters community function and by extension ecosystem processes. Coastal sponge populations worldwide are increasingly exposed to declining water quality that in several regions has resulted in mass sponge mortalities and reduced sponge diversity. In the Florida Keys (Florida, USA), for example, frequent …

Political Culture And Policy: The Impact Of Culture And Values On School Choice Legislation, Heather Leigh Neal

Educational Leadership & Workforce Development Theses & Dissertations

Policy actors unite political culture, power, and values to make substantial decisions which are often subjective in nature. Politics and policy are about collective decisions, which rely on the arrangement of a group of people. As values can influence policy actors in their attempt to solve problems, it is important for policymakers to establish a balance among the most essential values. A qualitative case study approach was used to investigate how, and what ways, political culture influenced how state stakeholders interpreted or implemented policy. Power and values were explored as both can connect for the implementation of policy. If values, …

Measuring And Modeling Bare Desert Wind Erosion From Steppe Grassland Of Northern China As Affected By Soil Moisture And Climate, Nicholas Morgan Potter

Civil & Environmental Engineering Theses & Dissertations

Soil erosion by wind has been found to be negatively related to soil water content, as evidenced by that for a given area, such a soil erosion can be much less in a wet than a dry year. However, few studies have examined the functional relationship between wind erosion and soil moisture, primarily due to lack of field measured data. The objectives of this study were to: 1) measure wind erosion in field using a portable wind tunnel devised and made by the author; 2) use the measured data to calibrate/validate a wind erosion model previously developed by the author; …
