Designing Neighborhood-Scale Green Infrastructure (Gi) To Improve The Health And Well-Being Of Industry-Adjacent Communities Through Air Pollution Mitigation In Joppa, Texas, Lauren Wardwell
Landscape Architecture Masters & Design Theses - Archive
Ambient outdoor air pollution kills roughly 4.2 million people every year worldwide and is linked as a contributing factor to diseases such as asthma, cancer, infertility, and neurological disorders. In the United States, minority communities are more likely to live near sources of air pollution, such as highways and industrial sites, and therefore face higher risks of developing the associated health difficulties. According to the Environmental Protection Agency (EPA), people of color (POC) are exposed to disproportionately higher levels of ambient fine particulate matter (PM) air pollution, regardless of income levels or region. While the EPA monitors and enforces outdoor …

Experimental Investigation Of Nonthermal Enhanced Oil Recovery Techniques For Improving Oil Recovery On Alaska North Slope, Yaoze Cheng
Engineering
Exploitation of viscous and heavy oils on Alaska North Slope (ANS) requires nonthermal enhanced oil recovery (EOR) techniques. Currently, three nonthermal EOR methods, including solvent injection, low salinity water (LSW) flooding, and low salinity polymer (LSP) injection, have been proved to be useful on ANS. ANS viscous and heavy oils can be developed effectively by combining those three nonthermal EOR techniques. In this dissertation, lab experiments have been conducted to investigate the potential of the proposed hybrid nonthermal EOR techniques, including HSW (high salinity water)-LSW-softened LSW flooding, HSW-LSW-LSP flooding, CO₂-enriched LHS (light hydrocarbon solvent)-alternating-LSW flooding, LHS-alternating-LSW flooding, CO₂-enriched LHS (light …
Coastal Wetland Carbon And Mineral Responses To Storm And Climate Change Through Time, At Cape Espenberg Alaska, Lindsey Michelle Smith
Coastal Wetland Carbon And Mineral Responses To Storm And Climate Change Through Time, At Cape Espenberg Alaska, Lindsey Michelle Smith
Geosciences
The Arctic is experiencing warming and ecological shifts due to climate change and the compounded effects of polar amplification. There is a deficit of information surrounding the carbon cycle response in Arctic Alaskan coastal marsh environments to these forces. The Cape Espenberg barrier beach system has been mostly preserved through time as a shoreline-parallel, linear geometry prograding geomorphic feature. This study determines the Arctic carbon and mineral accumulation trends in marsh environments at Cape Espenberg for both paleo (pre 1850 AD) and modern (post 1850 AD) timeframes. This project makes connections between the responses of carbon and mineral materials to …
Lipid Accumulation In Three Species Of Neocalanus Copepod In The Northern Gulf Of Alaska, Delaney M. Coleman
Lipid Accumulation In Three Species Of Neocalanus Copepod In The Northern Gulf Of Alaska, Delaney M. Coleman
Oceanography
The Northern Gulf of Alaska experiences pronounced seasonality and inter-annual variability characterized by a significant bloom of phytoplankton in the spring. Neocalanus copepods in the NGA have evolved to match their lifecycle to the seasonality of the Gulf of Alaska and feed upon the spring phytoplankton bloom. All three of these Neocalanus species utilize diapause as an over-wintering strategy; acquiring large stores of lipid to sustain them through winter hibernation and subsequent reproduction. Zooplankton were sampled with 150 and 505 µm mesh nets from 0 to 1200 m along the Seward Line and within Prince William Sound in the Northern …
Acoustic Detection And Characterization Of Sea Ice And Surface Waves In The Northeast Chukchi Sea, Savannah J. Sandy
Acoustic Detection And Characterization Of Sea Ice And Surface Waves In The Northeast Chukchi Sea, Savannah J. Sandy
Oceanography
Monitoring the status of Arctic marine ecosystems is aided by oceanographic moorings that autonomously collect data year-round. Near Hanna Shoal in the northeast Chukchi Sea, the Chukchi Ecosystem Observatory moorings include an ASL Environmental Sciences Acoustic Zooplankton Fish Profiler (AZFP) datalogger, a multi-frequency upward-looking sonar that is programmed to collect data from across the upper 30 m of the water column every 10-20 seconds. Using six years of nearly continuous data, here we describe a statistical analysis of the datalogger's 455 kHz acoustic backscatter return signal. When used in conjunction with a selforganizing map machine learning algorithm, these data allow …
A Place-Based Canoe Unit For Middle School Students, Laura Davies
A Place-Based Canoe Unit For Middle School Students, Laura Davies
Education
Behavior problems are steadily increasing at the middle school as a result ofthe COVID-19 pandemic and the trauma it caused in the students’ lives. Not only do educators want to reduce the behavior problems, but we also want students to feel safe and know that their individual needs will be met. Educators are striving to find creative ways to increase academic success, inspire students, teach important life skills and address social-emotional needs. One way I would like to address this is by creating a four week interdisciplinary place-based education unit focused on the significance and importance of canoes in Southeast …

Long Runs Of Homozygosity Are Correlated With Marriage Preferences Across Global Population Samples, Samali Anova Sahoo, Arslan A. Zaidi, Santosh Anagol, Iain Mathieson
Long Runs Of Homozygosity Are Correlated With Marriage Preferences Across Global Population Samples, Samali Anova Sahoo, Arslan A. Zaidi, Santosh Anagol, Iain Mathieson
Human Biology Open Access Pre-Prints
Children of consanguineous unions carry long runs of homozygosity (ROH) in their genomes, due to their parents’ recent shared ancestry. This increases the burden of recessive disease in populations with high levels of consanguinity and has been heavily studied in some groups. However, there has been little investigation of the broader effect of consanguinity on patterns of genetic variation on a global scale. Here, we collect published genetic data and information about marriage practice from 395 worldwide populations and show that reported preference for cousin marriage has a detectable association with the distribution of long ROH in this sample, increasing …

Zauthly: A Zero Trust Oauth2 Authorization Tool, Matthew Robert Perry
Zauthly: A Zero Trust Oauth2 Authorization Tool, Matthew Robert Perry
Computer Science
Controlling authentication and authorization is a pivotal part of managing modern web resources. Over the past decade, Oauth and OpenID Connect have shown that they are capable and secure protocols used for secure communication between the Identity Providers (IdP) and requesting parties that consume them. Zero Trust (ZT) architectures are based on authenticating individual requests instead of machines or networks. ZT has shown a pathway that enables a more secure flow oftrusted communication. This is done by defining the control systems and their counterpart the data systems. Zauthly applies ZT principles to Oauth2 flows to create a middleware service that …

A Quantum Mechanical Description Of The Diffusion Properties Of C1-C2 Hydrocarbon Molecules In Mof-74-Mg, Gemechis Degaga, Amanda Studinger, Loredana Valenzano-Slough
Michigan Tech Publications
Among the numerous metal organic framework (MOF) families, of significant importance is the MOF-74-M series (M = metal, -also known as CPO-27-M), characterized by a high density of not fully coordinated open metal site centers; this peculiarity has been demonstrated to translate into a higher hydrocarbons’ separation potential than other known MOFs and zeolites. To provide a more comprehensive description of the behavior of the hydrocarbon molecules within the MOF-74 cavity, diffusion processes and corresponding diffusion barriers of small hydrocarbons in the MOF-74-Mg were modeled. This work provides a description of the molecular transport processes of CH4, C2H2, C2H4 and …
An Econometric Analysis Of Collegiate Player Performance To Create A Model For Forecasting Contributions To Team Success, Evan Seely
Undergraduate Theses
At the conclusion of each basketball season, each conference selects 1st, 2nd, and sometimes 3rd all-conference teams based on player performance for that season. Often, these all-conference teams reflect biases in the media rather than evaluations based on player performance alone. The baseball statistic Wins Above Replacement, WAR, is useful in quantifying the impact of each player through the number of wins contributed to his respective team by comparing each player to a designated replacement level player. This statistic can also be applied to basketball analysis to perform a similar function as in baseball, despite …
Nine Ways Grandparenting Is Changing With The Covid-19 Pandemic, Madonna Harrington Meyer
Nine Ways Grandparenting Is Changing With The Covid-19 Pandemic, Madonna Harrington Meyer
Population Health Research Brief Series
Grandparents play a vital role in providing care for their grandchildren in the United States. However, long-term sociodemographic changes, including lower fertility rates and changes in employment and technology, along with massive upheavals prompted by the COVID-19 pandemic are changing grandparenting in important ways. This research brief describes these long-term sociodemographic changes and uses in-depth interviews conducted before the pandemic to illustrate nine specific ways grandparenting is shifting in the U.S. It concludes by calling for more supportive social welfare programs to support working families and reduce the reliance on grandparents for meeting childcare and financial needs.

The Multidimensional Test Anxiety Scale: A Latent Profile Analysis And An Examination Of Measurement Invariance, Gabrielle Francis
The Multidimensional Test Anxiety Scale: A Latent Profile Analysis And An Examination Of Measurement Invariance, Gabrielle Francis
USF Tampa Graduate Theses and Dissertations
Standardized testing is an integral part of the English and American education systems. The objectives of these tests are to evaluate students, teachers, and schools. However, this evaluation has unintended consequences, one of which is test anxiety. Over the last 50 years, there has been an increase in studies on test anxiety because of the widespread use of standardized tests (Hembree, 1988; von der Embse et al., 2019). However, two areas that have seen little attention are the measurement invariance of test anxiety scales across demographic groups, and the creation of classification standards for these test anxiety scales to increase …

Advanced Science Research Center
Skeletal stem cells (SSCs, or mesenchymal stromal cells typically referred to as mesenchymal stem cells from the bone marrow) are a dynamic progenitor population that can enter quiescence, self-renew or differentiate depending on regenerative demand and cues from their niche environment. However, ex vivo, in culture, they are grown typically on hard polystyrene surfaces, and this leads to rapid loss of the SSC phenotype. While materials are being developed that can control SSC growth and differentiation, very few examples of dynamic interfaces that reflect the plastic nature of the stem cells have, to date, been developed. Achieving such interfaces is …

Objectives: We evaluated the temporal trend in the use of opioid and nonopioid pain medications from a national survey.
Methods: Using data from the 2001 to 2018 National Health and Nutrition Examination Survey (NHANES), we examined the current use of prescription analgesics in the past 30 days among 50,201 respondents aged 20 years or older. Joinpoint regressions were used to test statistically meaningful trends of opioid vs nonopioid analgesics.
Results: The mean percentage of people who had …
The Effect Of Sea Otter Predation And Habitat Structure On Nearshore Crab Assemblages In Southeast Alaska, Rebecca Jeanette Cates
The Effect Of Sea Otter Predation And Habitat Structure On Nearshore Crab Assemblages In Southeast Alaska, Rebecca Jeanette Cates
Fisheries
Sea otter Enhydra lutris predation has resulted in conflict with humans for shared marine resources, as sea otters reduce the abundance and size of nearshore crabs. Several species of crab in Southeast Alaska are prey for sea otters including Cancer magister, a highly valued commercial and subsistence species, as well as Cancer gracilis, Cancer productus, and Telmessus cheiragonus, species that are abundant in the nearshore and of ecological and subsistence importance. Understanding the influence of sea otters and habitat structure on valuable crab species is of particular importance in Southeast Alaska as the abundance and range of sea otters expands …

At The Edge Of Somewhere: Journeying On The Dalton Highway, Charlotte A. Wheeler
Arctic and Northern Studies
Some journeys need to be made. In At the Edge of Somewhere, the writer embarks on a cycle ride from Fairbanks to Prudhoe Bay on Alaska's remote and dangerous Dalton Highway. Drawn obsessively to the Arctic sea ice some years earlier and, now, onto "the road," her journey attempts to bring closure to the long-standing need to be on the move, at once not able or even wanting to settle but also seeking a place within herself, and therefore a physical location, she might call home. She travels with a found notebook, acquired unexpectedly at the start of her ride, …
Towards A Cybersecurity Testbed For Agricultural Vehicles And Environments, Mark Freyhof, George Grispos, Santosh Pitla, Cody Stolle
Towards A Cybersecurity Testbed For Agricultural Vehicles And Environments, Mark Freyhof, George Grispos, Santosh Pitla, Cody Stolle
Department of Agricultural and Biological Systems Engineering: Faculty Publications
In today’s modern farm, an increasing number of agricultural systems and vehicles are connected to the Internet. While the benefits of networked agricultural machinery are attractive, this technological shift is also creating an environment that is conducive to cyberattacks. While previous research has focused on general cybersecurity concerns in the farming and agricultural industries, minimal research has focused on techniques for identifying security vulnerabilities within actual agricultural systems that could be exploited by cybercriminals. Hence, this paper presents STAVE – a Security Testbed for Agricultural Vehicles and Environments – as a potential solution to assist with the identification of cybersecurity …
Drivers And Mechanisms Of Migration In An Arctic Caribou Herd, Matthew D. Cameron
Drivers And Mechanisms Of Migration In An Arctic Caribou Herd, Matthew D. Cameron
Biological Sciences
Migration is one of the world's great natural wonders and the scale of some migratory journeys is astounding. Yet migration is globally imperiled and effective conservation of the remaining migrations will require a thorough understanding of the drivers and mechanisms underlying how migrants complete such journeys. In this dissertation, I present three chapters that sought to better understand spring and autumn migration for the Western Arctic Herd, a population of barren-ground caribou (Rangifer tarandus) that complete some of the longest terrestrial migrations on the planet. In the first chapter, I applied and validated an analytical method to infer parturition events …

Biochar has proven its potential in removing heavy metal ions from water. The objective of this study was to evaluate locally obtained biomass feedstocks for biochar production and their efficiency as a sorbent for aqueous lead (Pb2+) removal. The biomass feedstocks consisted of avocado seed, avocado peel, grapefruit peel, and brown seaweed, which represent agricultural and marine biomasses. The biochar materials were produced in two different methods: (1) a laboratory tube furnace at 300 °C and (2) a Do-It-Yourself (DIY) biochar maker, “BioCharlie Log”. The biochars were characterized for selected physicochemical properties, and batch adsorption tests with 10 …
An Analysis Of Turbulent Effects On Hydrokinetic Power Generation, Emily A. Browning
An Analysis Of Turbulent Effects On Hydrokinetic Power Generation, Emily A. Browning
Engineering
The effects of turbulence on power generation from a Current Energy Converter (CEC) are not fully understood. This thesis investigates the correlation between a vertical axis CEC's power output and the water velocity in the frequency and time domains. Chapter 2 shows the correlation between velocity and electrical power in frequency space. This correlation gives insight into the size of eddies that influence the CEC's power output. The results of this correlation analysis show that eddies of diameter around 0.8m have a noticeable impact on the power generation. Calculating the observed average integral length scale, the range of eddy diameters …
Application Of Probabilistic Decline Curve Analysis To Unconventional Reservoirs, Uchenna C. Egbe
Application Of Probabilistic Decline Curve Analysis To Unconventional Reservoirs, Uchenna C. Egbe
Engineering
This work presents the various probabilistic methodology for forecasting petroleum production in shale reservoirs. Two statistical methods are investigated, Bayesian and frequentist, combined with various decline curve deterministic models. A robust analysis of well-completion properties and how they affect the production forecast is carried out. Lastly, a look into the uncertainties introduced by the statistical methods and the decline curve models are investigated to discover any correlation and plays that otherwise would not be apparent. We investigated two Bayesian methods - Absolute Bayesian Computation (ABC) and GIBBS sampler - and two frequentist methods - Conventional Bootstrap (BS) and Modified Bootstrap …
