Young Adults’ Cohabitation And Dating Decisions During The Covid-19 Pandemic: A Qualitative Exploration Of Romantic And Developmental Context, Tyler B. Jamison, Jeremy B. Kanter

Faculty Publications

The COVID-19 pandemic caused significant upheaval for couples and families, particularly in terms of living arrangements. Emerging adults had to make quick decisions about where and with whom to shelter in place. In this grounded theory study, we explored how 22 young adults, predominantly living in the United States, navigated relationship decisions during the pandemic. The results suggest that participants were intentional about their choices, particularly in terms of moving in together (or not). The pandemic sometimes changed the timing of cohabitation or the pace of dating relationships; however, these decisions unfolded in tandem with common developmental tasks, such as …

Finding Synergy: Improving Biopesticide Efficacy For Disease Control Through Co-Application With The Natural Product Chitosan, Liza M. Degenring

Doctoral Dissertations

Annual crop losses caused by plant diseases are estimated worldwide at 220 billion US dollars. Conventional fungicides are the primary means to control these diseases, however there are growing concerns over human health, effects on non-target species, and environmental contamination. Furthermore, many plant pathogens have developed fungicide resistance due to overexposure to chemicals with single modes of action. There is a worldwide trend to explore alternative tools to reduce the use of synthetic fungicides while continuing to reduce plant disease. Among these control strategies are the use of antagonistic microorganisms (biopesticides) and naturally occurring compounds that have fungicidal activity. Chitosan …

Conditionally Automated Vehicles As A Safe And Productive Workspace, Nabil Al Nahin Ch

Doctoral Dissertations

Future automated vehicles will allow drivers to reclaim some of their driving time and perform personal or work-related activities while the car is in automated driving mode. However, traditional automotive user interfaces (UIs) are not designed to support such activities. For a vehicle to be considered a safe and productive workspace, we will have to explore how drivers can interact with emerging UIs in a car to engage in complex non-driving related tasks (NDRTs) and safely resume driving when needed. In the second chapter of this thesis, we present a user-elicitation study where we investigate how drivers would want to …

Acoustic Waveform Optimization For Three-Dimensional Object Geometries, Justin Ng

Doctoral Dissertations

In recent years, deep learning (DL) has become an increasingly important tool for many different types of classification, identification, and related problems including inverse radar and sonar applications. This thesis studies the degree to which radar and sonar systems may be optimized for DL algorithms in a theoretical setting. Most of the current existing literature found on using DL involve solving a full inverse scattering problem (ISP), that is to determine the properties and/or geometry of the scatter from nearly complete measurements of the scattered field. Methods suitable for use in two-dimensional space have been proposed and demonstrated with varying …

Non-Equilibrium Multiphase Particle Morphologies: Synthesis, Functionalization & Modeling, Yung-Chun Lin

Doctoral Dissertations

Waterborne technology highlights the advantage of using water as the dispersed media to replace the need for organic solvents. Emulsion polymerization is one of the most important techniques to produce functional polymer colloids of industrial importance. Besides the choice of monomers in the reaction, composite particle morphology significantly influences the mechanical properties of the materials in the applications of architectural coatings, adhesives, printing inks, and impact resistant plastics. Generally, emulsion polymerization produces spherical particles in the presence of water due to surface tension forces. In seeded emulsion polymerization, composite particles containing two incompatible phases can lead to various anomalous structures …

Black Phosphorus/Carbon Nitride Heterojunctions For Solar Fuel Generation, Nicholas Pollak

Doctoral Dissertations

Solar fuel generation has garnered attention in recent years as a renewable source for syngas (hydrogen and carbon monoxide) evolution. Difficulty in designing one-pot systems that can generate tunable ratios of hydrogen and carbon monoxide gases has persisted. In this thesis, a photocatalytic system for the generation of syngas under simulated solar irradiance is described that satisfies these challenges using black phosphorus (BP) and carbon nitride loaded with Co2+ active sites (Co@C3N4) to form a heterojunction. This thesis will present the ability to tune the syngas ratio by controlling the %wt of BP in the heterojunction. The oxidative power of …

Physiological And Biochemical Analysis Of The Nitrogen Metabolism And Lead Treatment In Hybrid Poplar Clone Nm6 (Populus Nigra L. X P. Maximowiczii A. Henry), Medini Weerasinghe

Doctoral Dissertations

ABSTRACTThe first objective of my Ph.D. research was focused on understanding the reasoning for changes observed in the physiology and metabolism of the poplar plants in response to foliar application of nitrogen. Increased use of nitrogen in the soil in agriculture, in the form of nitrogen fertilizers, has helped to promote high-yield agriculture over the past decades. However, a large fraction of nitrogen applied to croplands in the form of fertilizer and manure ends up entering the freshwater system causing degradation of the water quality and eutrophication of groundwater, rivers, lakes, and coastal and marine ecosystems. Chemical fertilization is also …

Essays In Public Policy And Mental Health, Bryce Stanley

Doctoral Dissertations

In this work I examine how various public policies can influence mental health outcomes. As mental health issues can be created or exacerbated by numerous different factors, many types of public policy can have mental health implications, perhaps not always intended by policy makers. In many cases, these implications are ambiguous from a theoretical level, making empirical research in the area important. Specifically, I model how labor market policies with minimum wages and Earned Income Tax Credit, health policy with the Dependent Coverage Mandate aspect of the Affordable Care Act, and social policy with recreational cannabis laws impact mental health …

Securing Approximate Computing Systems, Pruthvy Yellu

Doctoral Dissertations

Approximate Computing (AC) techniques have been leveraged to improve computing performance and energy efficiency with minor degradation in accuracy. Different than conventional computing, AC allows the computation to deviate from the reference or deterministic execution behavior. Thus, AC has emerged as a new paradigm of computing systems, especially for the applications such as image processing, audio recognition, and artificial intelligence. The majority of research efforts on approximate computing focus on new approximation mechanism design and implementation, rather than examining the security vulnerabilities of AC systems. To fill this gap, we first analyze the potential security threats induced by the AC …

Homesteading In Maine: Motivations And Current Trends, Alexandrea Merchant

Master's Theses and Capstones

People in the United States who practice the alternative lifestyle of “homesteading” seek to live self-sufficient lives by growing food, building dwellings, and living with resolute autonomy. Great variation exists in the degree of self-sufficiency attained and desired by individuals engaged in homesteading. It was the purpose of this study to illuminate the motivations underlying adopting and engagement in this lifestyle in Maine homesteaders. Through interviews with 10 homesteaders in Maine and participant observation, I documented the narratives and elucidated the motivations of this under researched group. Common themes emerged. Participants expressed concerns about personal health, the environment, and institutions. …

Effects Of Perennial Forage Composition And Harvest Intensity On The Weed Seedbank Community, Lilly E. Hartman

Master's Theses and Capstones

Most arable weeds arise from a resident soil seedbank and are typically controlled with tillage and herbicides, each of which pose sustainability challenges to growers and consumers. However, agronomic management practices that reduce weed seed input to the seedbank and that accelerate mortality of seeds already in the soil could reduce the need for more conventional weed control. Previous research and farmer practice has demonstrated that rotation of annual crops with several years of perennial forage can reduce weed abundance and the need for chemical weed control. In perennial forage systems, crop species and harvest intensity may have important effects …

Multi-Level Barriers And Opportunities For Nutrition Access In New Hampshire Hispanic Communities, Brooke Kelleher

Master's Theses and Capstones

The US Hispanic population, which has doubled in size in New Hampshire (NH) over the last decade, experiences a high prevalence of cardiometabolic disease and food insecurity. Fiber intake, which can be protective against cardiometabolic disease, decreases in Hispanics after a period of living in US food environments. Multi-level approaches have been effective at addressing diet quality and cardiometabolic disease in vulnerable populations and are warranted in NH Hispanic communities. Using the Socioecological Model (SEM), this thesis examined the influences of the individual, setting, sector, and social/cultural SEM levels on access to nutritious foods in Hispanic/Latino communities in NH. Additionally, …

Mass Loading Model Of Per- And Polyfluoroalkyl Substances To New Hampshire's Great Bay With A Focus On Surface Waters, Gage Moran

Master's Theses and Capstones

Per- and polyfluoroalkyl substances (PFAS) have been used in manufacturing as textile stains, soil repellants, grease proof products, food product coatings, aqueous film forming foams, and more for over 50 years. The carbon-fluorine chain of these compounds is chemically and thermally stable, resistant to biodegradation, and has both hydrophobic and lipophobic properties, making its chemistry unique for many commercial and industrial uses. This research work gathered existing concentration information from New Hampshire’s Environmental Monitoring Database on PFAS in the watershed and discharging to the Great Bay to better frame monitoring locations, temporal trends, and data gaps in the watershed. A …

“An Alarming State Of Evil Among Our Juveniles” A Case Study Of Public Education In Manchester, New Hampshire From 1845-1915, Amy Cummings Sherr

Master's Theses and Capstones

This thesis investigates the effectiveness of compulsory public education laws in Manchester, New Hampshire from 1845-1915, drawing on detailed quantitative and qualitative analysis of school attendance records, legislative proceedings, and media coverage. The thesis identifies shifting objectives in the campaigns for compulsory education laws and child labor laws in New Hampshire over the course of the nineteenth and twentieth centuries which help to explain lackluster enforcement. Reformers re-defined the perceived problems over time which led to new legislation and changing priorities in enforcement. Initially, reformers focused on “idle children” causing trouble and disrupting society. Then with mass immigration to the …

Evaluation Of A Wave Powered Water Pump Performance By Ocean Field Testing And Wec-Sim Modeling, Chelsea Kimball

Master's Theses and Capstones

A rising demand for macroalgae (or seaweed) has led researchers to seek out methods of increasing macroalgae aquaculture yields. Macroalgae is a food product, and may be used in biofuel, animal feed, and fertilizer. Applying upwelling technology to macroalgae aquaculture has been shown to increase biomass yield. A wave-powered upwelling device (or water pump) generates cold, nutrient-rich water flow to the surface of an aquaculture operation. A wave pump device developed at University of New Hampshire was refurbished and outfitted with instrumentation to determine its performance. Testing in the laboratory on both the device and instrumentation was conducted to prepare …
