Rotten Through The Cores: What Decomposition Can Tell Us About Carbon Cycling, Eileen C. Reeves

Dissertations, Master's Theses and Master's Reports

Sequestration of carbon (C) in forests means that the C is stored in the ecosystem and not emitted to the atmosphere, thus slowing the accumulation of greenhouse gases and mitigating the acceleration of manmade climate change. Quantifying the pools and fluxes of C in forests is therefore of considerable interest to landowners, policy makers, and scientists.

Decomposition is an ecological process central to the movement of C through ecosystems. This dissertation uses several techniques to help determine the factors influencing the speed of decomposition and long-term fate of decomposed plant material. In Chapter Two, phospholipid fatty acid analysis was used …

Examining The Role Of Plant Genome Size And Polyploidy In Shaping Arbuscular Mycorrhizal Fungi Symbioses, Abbigail J. Blackwell

Dissertations, Master's Theses and Master's Reports

Polyploid and larger genome size plants have been shown to contain more cellular nitrogen and phosphorus than related diploid and smaller genome size plants, indicating they have greater nutrient requirements. Given that arbuscular mycorrhizal fungi (AMF) associations can enhance plant nutrient acquisition, polyploid and larger genome size plants may form more associations with AMF to meet their increased nutrient demands and gain greater benefits from these symbioses. However, because AMF associations become unnecessary when nutrient-rich soils meet plant needs independently, these interactions may be more likely to occur under nutrient-poor conditions. For this research, we conducted two experiments to examine …

Ireland’S Best Kept Secret: The Unique Role Of Home Management Advisors In Supporting Families In The Community, Sonya Coffey, Amanda Mccloat, Elaine Mooney

Irish Journal of Applied Social Studies

In Ireland, early intervention family support models are the focus of researchers and policy makers. One such model, the Home Management Advisory (HMA) service, provided in the main by home economists, delivers education, support and advice to families on all aspects of home management. A qualitative examination of the role of home management advisors, underpinned by a strengths-based approach, was conducted through in depth semi-structured interviews with past and present advisors. The study aimed to gain insights into their experiences in delivering community-based family support. The study found service provision is limited to a small geographical area in the West …

Implementing A Z-Course Program At Fort Hays State University, Claire Nickerson

Library Faculty Publications

In 2018, the Fort Hays State University (FHSU) Open Educational Resource (OER) Committee proposed a Z-Course Program to track and incentivize the use of zero-cost course materials. It included a course-marking initiative, the implementation of a small cost-share fee to students to fund the program and incentivize departments to offer Z-courses, and a Z-Course Grant Program for faculty who wanted to convert their courses. The proposal was approved in 2020 and implemented beginning in 2021. Since then, the course-marking and fee implementation have been streamlined, and the committee is working on qualitative assessment.

Between "Hippies In Suits" And "Money Is The Name Of The Game": Farm Animal Advocates' Analyses Of Political Power In The Farm Bill, Jeff Thomas

Theses and Dissertations

The animal agriculture industry annually slaughters roughly ten billion land animals in the United States. What can be done to improve their welfare and lessen their suffering?

Over the past decade, the problem of farm animal welfare and suffering has drawn increasing interest from the effective altruism community, a loose movement of utilitarian advocates seeking technocratic solutions to social problems (Singer, 2015). As effective altruism has become a more potent driver of the animal welfare movement, an increasing number of nonprofits have begun engaging in political advocacy for farm animal welfare. Facebook co-founder Dustin Moskovitz’ Open Philanthropy is the largest …

Subgingival Microbiomes Of Healthy And Periodontitis Subjects, Tareq Abdulrasoul

Theses and Dissertations

Background: Periodontitis is a common chronic inflammatory disease triggered by the dysbiosis of the subgingival microbiome. 16s rRNA sequencing has been used to profile the subgingival plaque samples in healthy and periodontitis subjects. Here, we have collected subgingival plaque samples from subjects and analyzed the microbiome profile from 16s rRNA sequencing. We hypothesized that periodontitis patients will have a different subgingival microbiome profile than that of healthy subjects.

Methods: Subgingival plaque samples were collected from periodontitis and healthy subjects who were indicated for periodontal surgeries (osseous resective and regenerative surgery for periodontitis patients or crown lengthening for healthy …

Cannabis Use Among Cancer Survivors And The Impact On Cancer-Related Pain, Tiffanie A. Vargas

Theses and Dissertations

With a growing population of older adult cancer survivors—many of whom experience cancer-related pain—interest in medical cannabis as a pain management strategy has increased. This secondary analysis used data from the 2022 U.S. Behavioral Risk Factor Surveillance System (BRFSS) to examine cannabis use behaviors among cancer survivors and assess associations with cancer-related pain. The study had three aims: (1) to describe 30-day cannabis use (prevalence, intensity, and administration routes) by chronic health condition and cancer diagnosis, focusing on non-melanoma skin cancer, melanoma, and other cancers; (2) to compare demographics, health characteristics, and tobacco use by cannabis use status among cancer …

Substrate Preference And Foraging Behavior Of Two Declining Warblers In Appalachian Shrublands, Samantha Fishman

Theses and Dissertations

Abstract Shrubland and early successional habitats (ESH) support a diversity of wildlife, including many declining songbirds. However, nonnative shrubs increasingly dominate these habitats, potentially altering habitat quality by influencing prey availability. Habitat quality can be assessed by observing foraging behaviors of songbirds and identifying preferred and avoided substrates as well as testing the predictions of optimal foraging theory; specifically that birds will maximize their energy gain relative to the costs. We examined foraging behaviors of Golden-winged Warblers (Vermivora chrysoptera; GWWA) and Chestnut-sided Warblers (Setophaga pensylvanica; CSWA) in ESH on private lands in Virginia with varying amounts …

Developing Bioinformatics Expertise Through The Annotation Of The Gut Microbiome Of Odontotaenius Disjunctus, Keidra E. Carter

Theses and Dissertations

Next-generation sequencing (NGS) technologies have revolutionized biological research by generating unprecedented volumes of genomic data, necessitating advanced bioinformatics tools and specialized expertise to fully interpret complex microbial communities. This study outlines an integrated workflow to characterize the gut microbiome of the wood-feeding beetle Odontotaenius disjunctus. Prokka is employed for functional annotation to identify protein-coding genes and other genomic features, while Kaiju is used for taxonomic classification. DIAMOND is then applied to locate and validate the taxonomic assignments generated by Kaiju by aligning sequences within the contigs to a comprehensive protein database, proGenomes. Functional analysis revealed that the contigs encode proteins …

Radical Hope Amid Generational Oppression And Puerto Rican Well-Being, Natalia Gomez Giuliani

Theses and Dissertations

Oppressive systems (e.g., colonialism, racism, capitalism) create a disparate distribution of power that, through various mechanisms, negatively impacts the health and well-being of members of the oppressed group. Boricuas have experienced over 500 years of oppression, with the island currently maintaining a colonial relationship with the United States. As these adverse effects of oppression are identified, the need for protective factors (e.g., hope) has emerged. This study explored how islander Boricuas practice radical hope, understand their history of oppression and resistance, and how they perceived it to impact their overall well-being. Utilizing a phenomenological qualitative approach, I conducted 15 semi-structured …

Using Habituation And Affective Forecasting To Distinguish When The Passive Enjoyment Of Harm Begets The Active Pursuit Of Aggression, Drew M. Parton

Theses and Dissertations

Understanding the antecedents and impellers of aggression is key to preventing violence, and individual differences have been identified as some of the key factors of interest in the study of aggression. Antisocial personality traits such as psychopathy, Machiavellianism, Narcissism, and Sadism have received considerable focus from researchers. Among these traits, Sadism stands above them all as arguably the most malevolent of all trait constructs in psychology. Sadism shows the strongest correlations with aggression among malevolent traits and is uniquely linked to unprovoked aggression, even when it is costly. Sadism thus represents an extreme risk factor for aggression, and studying its …

Place, Culture, And Care: A Socioecological Examination Of Type 2 Diabetes Among Hispanics In The U.S., Danielle Montoya

Theses and Dissertations

Introduction: Type 2 diabetes (T2D) disproportionately affects U.S. Hispanic populations. This dissertation examined whether structural determinants fundamentally drive T2D disparities among Hispanics, with attention to within-group racial heterogeneity.

Methods: Three studies utilized nationally representative data. Study 1 examined neighborhood segregation and ethnic enclave residence associations with T2D using restricted NHANES data (2011-2018, n=5,056). Study 2 investigated acculturation and T2D associations using restricted NHANES data (2011-2018, n=4,540). Study 3 analyzed patient-provider racial/ethnic concordance and adequate diabetes care using MEPS data (2008-2021, n=17,138).

Results: Structural factors demonstrated primacy across all studies. Neighborhood segregation (aOR=1.17, p>0.05) and ethnic enclave residence showed no …

The Kincare Craze In Child Protection: Romanticism, Subterfuge, And Racial Separatism, James G. Dwyer

Faculty Publications

Among recent developments in family law, the most prevalent issue on legislative agendas has been Kincare as an alternative to non-relative foster care when maltreated children cannot remain with parents. Long an available option legally but traditionally regarded with skepticism by child protection workers, Kincare is now idealized. A steady stream of state legislative bills aims to encourage or command child protection and foster care agencies to place maltreated children in the home of relatives or friends of their parents whenever one is available, ostensibly based on an assumption that this is categorically better for children than living with unrelated …

Learning Through Following: The Role Of Social Foraging In Juvenile Saddleback Tamarin (Leontocebus Weddelli Weddelli) Development In The Department Of Pando, Bolivia, Meghan E.F. Hanson

Graduate Research Theses & Dissertations

Across the primate order, the juvenile stage is an important period of development that transitions individuals from infancy to adulthood. During the juvenile stage, individuals are weaned but lack experience feeding and foraging on solid foods. As a result, juveniles must learn foraging and feeding skills during this vital period of growth and development. The purpose of this study is to assess how juvenile saddleback tamarins (Leontocebus weddelli) gain foraging and food manipulation skills. During this study, I observed feeding behaviors in a group containing two juveniles and four adults, located at the Estación Biológica Tahuamanu in the Department of …

Optimization Of Transformation And Regeneration In The Sunflower (Helianthus Annuus), Sara M. Kilar

Masters Theses

In addition to their value as prized ornamentals, sunflowers are important crop species due to the nutritional value and high oil content of the seeds. Sunflower oil is a significant contributor to global seed oil production, which can be used as a food additive and cooking agent as well as a raw material for biodiesel production. While traditional breeding efforts have led to the development of many unique cultivars, genetically modified variations have proven more difficult due to the recalcitrance of sunflower plants to genetic transformation. As a result, facile and efficient transformation methods for sunflowers have the potential to …

Influence Of Thermophilic Biofilms On Proliferation Of Opportunistic Pathogens In Domestic Water Systems, Olajumoke Akinbami

Masters Theses

Domestic hot-water systems quietly grow biofilms under elevated temperatures that can serve as shelter to Opportunistic Premise Plumbing Pathogens. Although focus has been placed on microbes in domestic systems, there has been no clear conclusion on the mechanism of survival and persistence of opportunistic pathogens despite various disinfection strategies. In this study, we determined the distinction between showerhead and drip-flow biofilms at the whole-community level and analyzed the coexistence of thermotolerant organisms with opportunistic genera, such as Legionella. We sampled eight showerheads and simulated four biofilm samples in the laboratory using the drip-flow biofilm reactor.

We observed a strong …
