Dune Building Dynamics Impact Cross-Island Connectivity And Barrier Island Characteristics, Alexander Sabo

Theses and Dissertations

Located at the land-sea interface, barrier islands are important protective features that reduce wave energy and erosion from mainland areas. Further, barrier islands provide habitat for many different organisms and serve as popular areas for recreation and tourism. As sandy landforms, barrier islands are easily disturbed, but often recover after disturbance as a result of island plant communities, specifically dune building grasses. Disturbance on barrier islands is driven by storms, tides, and overwash events. After disturbance has occurred, dune grasses colonize the dunes allowing for dune building and habitat restoration. On the Virginia barrier islands, there are three dominant dune …

Interiorization And Localization: An Analysis Of Immigration Enforcement In Local Contexts, Manuel N. Leiva

Theses and Dissertations

Immigration and Customs Enforcement (ICE) is a federal agency that plays a large role in surveilling, apprehending, detaining, incarcerating, and deporting undocumented immigrants in the United States. Due to constraints on the number of ICE’s available personnel and resources, the agency relies on deputizing, or devolving to local law enforcement agencies the authority to enforce federal immigration policies. Prior to the 1990s, the enforcement of policies directed at controlling flows of undocumented immigrants was generally under the purview of federal law enforcement agencies and administrators, not state or local ones. The attacks on September, 11^th 2001 represented a flashpoint, …

Educators’ And Administrators’ Perceptions, Challenges, And Changes Associated With School District Consolidation, Candace L. Gillespie

Theses and Dissertations

School district consolidation has been a trend throughout the United States as state departments of education are mandating that nearby school districts consolidate with other nearby districts. This trend is being mandated in an effort to decrease funds being spent by having many small districts. This includes funds being spent on salaries and schools, as schools consolidate due to districts consolidating. Schools, central offices, parent centers, and other buildings that are related to having multiple central offices close. Jobs are lost, policies change, and sometimes leadership changes. However, change is inevitable. With change comes different concepts, policies, and in some …

Human Trafficking: The Impact Of Covid-19 On Labor Trafficking In The Us, Anthony A. Mottola

Theses and Dissertations

Human trafficking is a global phenomenon where traffickers prey upon their victims without discriminating against age, gender, ethnic background, or nationality. The United States (US) is not immune to the human rights violations of human trafficking. The victims of human trafficking are coerced into a life of exploitation through forced labor or sexual exploitation. Many victims are migrants from disadvantaged countries that travel to the US seeking employment but end up the victims of abuse, both physically and mentally, at the hands of traffickers. In 2020, the COVID-19 pandemic devastated the global economy, forcing quarantines, travel bans, and social distancing. …

Evaluating Higher Education In Prison Effectiveness By Modality Through Student Success And Retention Rates In California Community Colleges, Peter Michael Fulks

Theses and Dissertations

There is a strident body of empirical research evidence that Higher Education in Prison (HEP) has a direct impact on reducing recidivism. Additionally for participants, it also increases the economic mobility and employability post-release. However, the ability to conduct randomly controlled trials with a distal measurement of recidivism is hindered due to the inconsistent industry definitions of recidivism. Considering the implementation of credit bearing college programs from California Community Colleges since Senate Bill 1391 in 2014, the study conducts statistical analysis through independent and paired t tests to determine which modality of delivery, face-to-face (F2F) or correspondence (COR), to provide …

Going Cold Turkey? Changes To Faunal Subsistence In The Northern San Juan Region From Basketmaker Ii Through Pueblo Iii, Tenaya Gatrell-Bedard

Theses and Dissertations

Previous research in the Northern San Juan Region of the American Southwest has revealed a pattern of change in subsistence patterns from the Basketmaker II through Pueblo III periods. Jonathan C. Driver describes the pattern as: cottontail in Basketmaker III (500 to 750 CE) and Pueblo I (750 to 900 CE), deer in Pueblo II (900 to 1150 CE), and turkey in Pueblo III (1150 to 1350 CE). The transition from deer to turkey as the main subsistence has been recorded at several sites throughout the Northern San Juan Region and is thought to be caused by the overhunting of …

Effect Of Climate History On The Genetic Structure Of An Antarctic Soil Nematode, Abigail C. Jackson

Theses and Dissertations

Historical climate disturbances such as glacial cycling and fluctuating stream, lake, and sea levels strongly influence the distribution and evolutionary trajectories of Antarctic terrestrial species. Antarctic invertebrates, with limited long-range mobility, including the ubiquitous sentinel nematode species Scottnema lindsayae, are especially sensitive to climate disturbances. We tested hypotheses associated with the historical geographic and population genetic structure of this species as it occurs across the McMurdo Dry Valleys (MDVs) of Antarctica. In order to reconstruct the influence of climate disturbance and ecological conditions on this species, partial mitochondrial COI gene sequences were sequenced and analyzed from individual S. lindsayae collected …

The Effect Of Gut Microbiota On Overwintering Success In Mule Deer, Emma Wilcox

Theses and Dissertations

Mule deer are an important rangeland grazer, large prey species, and game animal for the state of Utah, so herd size is monitored and managed actively. A significant cause of population decline is poor overwintering survival, including from the lack of available forage during winter months. Mule deer energy storage is correlated with greater overwintering success, so physical estimates of energy storage including body condition score (BCS), rump fat (RF), and loin thickness (LT), can be used to track and predict a herd's health. Current methods of collecting deer information are costly, time consuming, and cause physical stress to deer, …

Is Teaching Experience A Predictor For School Psychologists' Confidence And Competence In Behavior Intervention Plans?, Misty Dawn Lainé Coplan

Theses and Dissertations

The Individuals with Disabilities Education Improvement Act (IDEIA) introduced Behavior Intervention Plans (BIPs) into United States law in 1990, and the reauthorization of IDEIA occurred in 2004. Even though BIPs have been codified into law, school personnel struggle to meet BIP mandates due to poor implementation fidelity. Barriers for BIP implementation are varied, but there is little research regarding whether practitioner competence and confidence through teaching experience is a factor. School psychologists (N = 122) from eight states completed a self-evaluation survey using the tailored design method. Results from the survey compared responses from school psychologists with and without teaching …

Localization Of Open Educational Resources By Facilitators Of A Human Rights Course In Ghana, Emily Durham Bradshaw

Theses and Dissertations

Research on the use of Open Educational Resources (OER) often notes the potential benefits for users to revise, reuse, and remix OER to localize it for specific learners. However, a gap in the literature exists in terms of research that explores how this localization occurs in practice. This is a significant gap given the current flow of OER from higher-income countries in the Global North to lower-income countries in the Global South (King et al., 2018). This study explores how OER from one area of the world is localized when it is used in a different cultural context. As part …

Geologic Mapping Of The Sparta 7.5-Minute Quadrangle In Northern Mississippi Via Remote Sensing, Traditional Geologic Survey, And Applied Geospatial Information Systems Methods, Rayford Dean Parnell

Theses and Dissertations

Traditional geologic mapping involves substantial time and labor in the field as geologic contacts are manually examined and interpreted. The processes of mapping geologic contacts can be condensed into a quicker and less laborious process using advances in remote sensing and GIS (geospatial information systems), including increased resolution and computerized data management and interpretation. Application of these advances reduces the costs and time of geologic mapping. The Sparta 7.5-minute quadrangle provides a mostly unaltered view of regional Paleocene and Upper Cretaceous geology due to its rural locale, lack of development, and stream topography. Recently LiDAR (Light Detection And Ranging) survey …

Design, Development And Evaluation Of The Ruggedized Edge Computing Node (Recon), Sahil Girin Patel

Theses and Dissertations

The increased quality and quantity of sensors provide an ever-increasing capability to collect large quantities of high-quality data in the field. Research devoted to translating that data is progressing rapidly; however, translating field data into usable information can require high performance computing capabilities. While high performance computing (HPC) resources are available in centralized facilities, bandwidth, latency, security and other limitations inherent to edge location in field sensor applications may prevent HPC resources from being used in a timely fashion necessary for potential United States Army Corps of Engineers (USACE) field applications. To address these limitations, the design requirements for RECON …

A Multi-Method Exploration Of Health Disparities And Covid-19 Incidence And Mortality In The United States, S M Asger Ali

Theses and Dissertations

The 21^st century experienced several health crises, especially in the form of infectious disease outbreaks such as the SARS outbreak in 2003, the H1N1 in 2009, and Ebola outbreaks in 2013. However, none has produced a worldwide socio-economic and health impact compared to the recent pandemic, known as COVID-19. As of October 4, 2022, more than 614 million cases with 6 million deaths have been reported worldwide. The United States is currently in the leading position with more than 98 million cases and 1 million deaths. The pandemic, however, did not impact the entire region similarly, and the infections …

Towards Structured Planning And Learning At The State Fisheries Agency Scale, Caleb A. Aldridge

Theses and Dissertations

Inland recreational fisheries has grown philosophically and scientifically to consider economic and sociopolitical aspects (non-biological) in addition to the biological. However, integrating biological and non-biological aspects of inland fisheries has been challenging. Thus, an opportunity exists to develop approaches and tools which operationalize planning and decision-making processes which include biological and non-biological aspects of a fishery. This dissertation expands the idea that a core set of goals and objectives is shared among and within inland fisheries agencies; that many routine operations of inland fisheries managers can be regimented or standardized; and the novel concept that current information and operations can …

Forecasting Ride-Hailing Across Multiple Model Frameworks, Christopher Stephen Day

Theses and Dissertations

The advent of on-demand transport modes such as ride-hailing and microtransit has challenged forecasters to develop new methods of forecasting the use and impacts of such modes. In particular, there is some professional disagreement about the relative role of activity-based transportation behavior models -- which have detailed understanding of the person making a trip and its purpose -- and multi-agent demand simulations which may have a better understanding of the availability and service characteristics of on-demand services. A particular question surrounds how the relative strengths of these two approaches might be successfully paired in practice. Using daily plans generated by …

Evolutionary Cartographies Of Language Diversification: Quantitative Approaches To The Geolinguistic Mapping Of The Kayanic Languages (Central Borneo), Deandré A. Espree-Conaway

Theses and Dissertations

Why are there so many languages in the world and how did this diversity come about? Every day, humans around the world speak over 7,000 languages. One of the most impactful theories describing the processes and mechanisms of language diversification is that of the Linguistic Niche Hypothesis (Lupyan & Dale 2010). The Linguistic Niche Hypothesis suggests that languages adapt to their environments (Lupyan & Dale 2010: 1). Lupyan and Dale describe it, stating that "just as biological organisms are shaped by ecological niches, languages structures...adapt to the environment (niche) in which they are being learned and used" (2010: 1). Taking …
