Finding The Best Predictors For Foot Traffic In Us Seafood Restaurants, Isabel Paige Beaulieu

Honors Theses and Capstones

COVID-19 caused state and nation-wide lockdowns, which altered human foot traffic, especially in restaurants. The seafood sector in particular suffered greatly as there was an increase in illegal fishing, it is made up of perishable goods, it is seasonal in some places, and imports and exports were slowed. Foot traffic data is useful for business owners to have to know how much to order, how many employees to schedule, etc. One issue is that the data is very expensive, hard to get, and not available until months after it is recorded. Our goal is to not only find covariates that …

Uncovering The Interest Of Private Landowners In Learning More About Landscaping With Native Plants, Catherine A. Taylor

Honors Theses and Capstones

Increasing populations in New England and the subsequent residential development associated with this growth has had profound impacts on local ecosystems. Residential development often results in habitat loss and fragmentation (Radeloff et al, 2009). Habitat fragmentation, or dividing habitat into smaller, less dense parts, can induce the decline of local populations of native species and interrupt vital ecosystem services. Important services offered by functioning ecosystems include carbon sequestration, flood reduction, and water purification. It has been shown that benefits can be restored to local ecosystems through strategies to restore ecosystem functions (Burghardt et al, 2008). On an individual household scale, …

Distributed Partial Differential Equation Solving With Julia Fast Fourier Transform Library, Christopher E. Mottola

Honors Theses and Capstones

Scientific computing relies on advanced computational and mathematical techniques to solve complex problems in scientific domains. For the numerical rendering of spectral, nonlinear, and dynamic phenomena, there is a growing need for greater availability of a broad class of Fourier-based algorithms to perform large scale operations on multidimensional data in distributed and optimized ways.

Tropicalization Of Seagrass Macrophytodetritus Accumulations And Associated Food Webs, Gilles Lepoint, Glenn A. Hyndes

Research outputs 2022 to 2026

Seagrass, systems export significant amounts of their primary production as large detritus (i.e. macrophytodetritus). Accumulations of exported macrophytodetritus (AEM) are found in many areas in coastal environment. Dead seagrass leaves are often a dominant component of these accumulations, offering shelter and/or food to numerous organisms. AEM are particular habitats, different from donor habitats (i.e. seagrass meadow, kelp or macroalgae habitats) and with their own characteristics and dynamics. They have received less attention than donor habitats despite the fact they often connect different coastal habitats, are the place of intense remineralization processes and shelter associated detritus food web. As for seagrass …

College of Graduate Studies: Theses & Dissertations

Nasonia is a parasitoid wasp genus that serves as an emerging model for studying speciation due to an incompatibility between nuclear and mitochondrial genomes between sister taxa. Short generation times, easy rearing in a lab setting, producing large amounts of progeny, and whole genome sequencing make Nasonia is an excellent candidate for studying incomplete reproductive isolation. Nasonia have five chromosomes and exhibit haplo-diploid sex determination in which fertilized eggs develop into diploid females and unfertilized eggs develop into haploid males. Recessive phenotypes are hidden in diploid females but are laid bare in haploid males as there is no interaction between …

Investigating The Effect Of A Facultative Symbiont, Hamiltonella Defensa, On Pea Aphid, Acyrthosiphon Pisum, Fecundity And Behavior In Elevated Co₂ Atmospheres, Tyler J. Follman

College of Graduate Studies: Theses & Dissertations

As atmospheric carbon dioxide (CO₂) levels continue to rise, it is important to study how economically important organisms, like the pea aphid, Acyrthosiphon pisum, will react to these conditions. The pea aphid feeds on the phloem of crop plants like alfalfa, peas, and fava beans, where it not only directly harms the plant but also can spread plant viruses. A wide variety of factors can influence pea aphid fecundity and behavior. Some of these factors are abiotic, like atmospheric conditions, and some are biotic, like microorganisms with which the pea aphid has a mutualistic relationship. In this thesis, …

Non-Inferiority Testing: Kernel Estimation And Overlap Measure, Larie C. Ward

College of Graduate Studies: Theses & Dissertations

In non-inferiority testing, the decision of whether a proposed treatment is non-inferior to a reference treatment depends on model assumptions and choices of acceptable tolerance limits. Here, we consider a method that employs kernels to estimate the probability density functions of both the experimental and reference populations from two independent samples. Based on these densities, we introduce a quantity called the overlap coefficient or overlap measure. A bootstrap technique is helpful in exploring the distribution and variance empirically. We derive the distribution of this measure and define a hypothesis test that can be applied to the non-inferiority setting under some …

Structural And Functional Characterization Of Two Poly(Aspartic Acid) Hydrolases, Amanda Jansch

College of Graduate Studies: Theses & Dissertations

Due to the accumulation of polymers in the environment, biodegradable alternatives should be used in place of commonly used polymers like poly(carboxylates). Poly(carboxylates) are water-soluble polymers (WSPs) that make up a variety of consumer products, such as detergents, descaling agents, and superabsorbent materials commonly found in diapers and feminine hygiene products. While the visible accumulation of these products may not be obvious, it is necessary to reduce the amount entering the environment. Poly(aspartic acid) (PAA) is an alternative WSP that is biodegradable through the action of three different enzymes, PahZ1_KT-1, PahZ2_KT-1, and PahZ1_KP-2. Originally …

Ecological Restoration Of Lead/Zinc/Copper Mine Tailings: Phytomanagement And Amendment Strategies To Enhance Substrate Functionality And Biomass Production, Mariam K. Al-Lami

Doctoral Dissertations

“The extreme physiochemical characteristics of mine tailings inhibit microbial processes and natural plant growth. Consequently, vast and numerous tailings sites remain barren for decades and highly susceptible to wind and water erosion. Phytostabilization is a cost-effective and ecologically productive remediation approach; however, tailings revegetation is generally challenging and must often be assisted with appropriate soil amendments. Amendments applied individually in greenhouse studies discussed herein revealed notable improvement in bioenergy crops growth only with biosolids treatments. Recalcitrant carbon amendments (biochar and humus) showed notable impact only on tailings physichochemical and hydraulic properties. Nevertheless, biosolids may not support sustained vegetation due to …

Theoretical And Experimental Application Of Neural Networks In Spaceflight Control Systems, Pavel Galchenko

Post-Grant Adjudication Of Drug Patents: Agency And/Or Court?, Arti K. Rai, Saurabh Vishnubhakat, Jorge Lemus, Erik Hovenkamp

Articles

The America Invents Act of 2011 (AIA) created a robust administrative system-the Patent Trial and Appeal Board (PTAB)-that provides a route for challenging the validity of granted patents outside of district courts. Congress determined that administrative adjudication of the validity of initial patent grants could be cheaper and more scientifically accurate than district court adjudication of such validity.

For private economic value per patent, few areas of technology can match the biopharmaceutical industry. This is particularly true for small-molecule drugs. A billion-dollar drug monopoly may be protected from competition by a relatively small number of patents. Accordingly, the social cost …

Validation Of Edna Metabarcoding : A Comparison To Traditional Survey Methods In Ozark Streams, Veronica Marian Lee

Masters Theses

Environmental DNA (eDNA) sampling provides a method for assessing fish communities that has potential as a supplement to traditional sampling methods due to its ability to save time as well as its non-invasive nature. This is a method in which from just one sample, eDNA from multiple individual species are able to be sequenced in tandem and the resulting reads identified to describe a community. In order to evaluate this technique and its efficacy for monitoring fish community diversity, we collected water samples alongside surveys performed by the Missouri Department of Conservation sampling program in summers 2020-21. DNA were extracted …

Ecology Of Family Experiences: Contextualizing Family Leisure For Human Development & Family Relations, Karen K. Melton, Camilla Hodge, Mat D. Duerden

Faculty Publications

All family leisure is not equal. Yet, little is known about the mechanisms linking different types of family leisure to different human development and family relations outcomes. The Ecology of Family Experiences (EFE) framework provides a sensitizing lens for the study of the conditions under which family leisure is beneficial to individuals and families. Specifically, the framework suggests three domains—Family, Activity, and Time—iteratively interact to generate different levels of individual and family outcomes (i.e., responses, meaning, and development). The EFE necessitates research built on ecologically valid study designs that incorporate innovative measurement approaches. Scholars using such approaches can increase the …
