Predicting Marching Band Ratings In Nebraska: A Quantitative Analysis Of Socioeconomic Status And Geographic Variables, Michael T. Genslinger

Doctoral Dissertations and Projects

Although the high school marching band has been a tradition in the United States for nearly a century, it is becoming increasingly rare in many rural areas. Despite economic barriers, some rural schools have overcome the challenges of their location and built successful instrumental music programs. Research on rural music education is vital because most new music educators in Nebraska will begin their careers teaching in rural schools. A quantitative study examined marching band performance in Nebraska, a highly rural state. The study reviewed NSBA State Marching Contest overall ratings from 2015 to 2024, along with a socioeconomic profile of …

Fostering Student Inquiry With Perspective Taking And Music: The Geography Detective Activity, William Gary G. Cole

Teaching Social Studies in the Peach State

This article introduces the Geography Detective activity, an inquiry-based instructional strategy that integrates perspective taking and music to foster student engagement and disciplinary thinking in a ninth-grade World Geography classroom. Centered on the song “Cecilia” by The Mulligan Brothers, the activity invites students to analyze lyrics as historical evidence, investigate geographical and historical contexts, and construct evidence-based interpretations of time, place, and events embedded within the narrative. Through guided and open-ended inquiry, students adopt the role of “history detectives,” grappling with ambiguity, evaluating sources, and defending plausible conclusions rather than seeking predetermined answers. Grounded in research on inquiry-based learning, perspective …

Walking The Map: Exploring Illinois Using Giant Traveling Maps, Irenea Walker, Kim Carthans

The Great Lakes Social Studies Journal

While it is common for any social studies discipline to receive limited instructional time in the elementary classroom, geography would be among the least taught (Bauml, 2023; Hinde, 2014). As a result, many students lack even the basic knowledge of geography, such as state capitals, geographical locations, and major landmarks. It is even more alarming that elementary students are unaware of the geography of their own state. National Geographic Society introduced giant floor traveling maps over a decade ago through each state’s National Geographic Alliance (2025). The gigantic floor map helps students get a sense of the map's places through …

Dividing To Survive, Fight, Or Ally: Understanding Terrorist Group Splintering, Makayla Wendland

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The splintering of terrorist groups is extremely common, with members breaking from the ranks of an existing organization to establish a new, independent organization. At times, the process of splintering has produced some of the deadliest terrorist groups globally, significantly affecting the trajectory and intensity of conflict. Conversely, there are times when splintering can produce groups that quickly dissipate without having an impact. This variation in lethality frames the question at the center of this dissertation: how do splinter groups behave and operate in their conflict landscape?

I develop a new theory-based typology to explain variations in the behavior and …

Redeveloping Mississippi: A Case Study On Brownfields In Central & Southern Mississippi, Sahrah R. Yeroozedek

Master's Theses

Brownfields, or properties that are or possibly are contaminated with dangerous materials, represent a common obstacle for communities in Mississippi. The real or potential presence of contaminants at these sites often deters investors due to costly cleanup requirements (EPA, n.d. -b). The Environmental Protection Agency (EPA), through its Brownfield Revitalization Program, implemented guidelines for covering the costs and labor associated with the remediation of these properties. The EPA is not, however, responsible for redevelopment that supports long-term environmental and economic sustainability. Although the EPA maintains inventories of all Brownfields, there is also no comprehensive database of Brownfields and their current …

Analyzing The Climate-Growth Response Of Hemlock Species In Tight Hollow, Daniel Boone National Forest, Kentucky, Usa, Jacob G. Brown

The Cardinal Edge

Kentucky’s (KY) local climate is facing uncertainty as the influence of climate change pushes hydrological variation to its extremes. Proxy-based data can be used to better understand this variation by analyzing past climatic conditions. Tree rings provide valuable proxy data on an annual to sub-annual resolution that can be used to create climate reconstructions. However, the state of Kentucky lacks high temporal and spatial resolution datasets for accurate climate reconstruction analysis. Climate-sensitive tree species and locations must be identified and evaluated within Kentucky to further enhance these datasets to a higher resolution. Our research objective is to analyze the climate-growth …

A Multilevel Analysis To Evaluate Variability In Sdoh Clusters Within Rurality And Its Effects On Cancer-Specific And All-Cause Mortality In The Us., Stephie Ann Abraham

Electronic Theses and Dissertations

Social determinants of health (SDOH) factors have consistently been shown to impact all-cause and cancer-specific mortality. Area-level SDOH factors that coexist to form “high-risk” clusters are more prevalent in rural than urban areas. However, heterogeneity within rural and urban areas may contribute to variations in SDOH factors that could influence higher mortality rates and is not considered in other studies. The primary objective of this study was to utilize ecological and individual-level data to determine if the composition of SDOH clusters within counties in the rural-urban continuum contributes to differences in all-cause (AC) and cancer-specific mortality rates of lung and …

The Transitional Human Being: Literary, Journalistic, And Cinematographic Representations Of The Twentieth- And The Twenty-First-Centuries Italy, Ron Kubati

Purdue Studies in Romance Literatures

This book analyzes the crisis of the idea of human being based on timeless notions, in the Euroamerican context, as seen primarily through literature and cinema. It focuses on Italy, which has been and remains a crossroads for diverse cultural and political currents—open to Mediterranean cultural influences while remaining within a typically Western cultural context. The “new man,” defined by Corrado Alvaro during his trip in Russia in 1934 as “transitional,” implies a human being with a fundamental need for change. Instead of the “new man,” Italo Calvino in the 1960 preface to his I nostri antenati wrote about the …

Geographic Patterns Of Educational Achievement: A Methodological Case Study Of Regression Modeling Approaches, Leokadia Lipien

USF Tampa Graduate Theses and Dissertations

This methodological case study introduces a novel approach to investigate the impact of student, teacher, and geographic factors on the academic achievement of virtual school students in Florida. Traditional linear regression models, and even multilevel models, often overlook spatial dependencies, which can lead to biased estimates and incomplete inferences. This research addresses this limitation by comparing a cross-classified multilevel model (CCMM) with a novel cross-classified spatial model (CCSM) that incorporates coefficients from geographically weighted regression (GWR). Utilizing secondary data from a statewide virtual school, including student demographics, teacher characteristics, and standardized test scores, along with U.S. Census Bureau data, the …

Migration In The Early Chesapeake: Dorchester Co., Md, As A Case Study, 1650–1750, Thomas Daniel Knight

History Faculty Publications

This article examines the migration patterns that shaped the early settlement of Dorchester County, Maryland. Dorchester County is located on Maryland’s Eastern Shore, an area distinctive in terms of its geography, history, and culture. In U.S. history, migration has generally proceeded from eastern areas to western ones and from northern areas to southern ones, a pattern dating back to the earliest colonial settlements. Settlement in Dorchester County proceeded primarily from east to west and south to north, with additional migration streams coming from the north out of Delaware and from the west out of Somerset County. This gave Dorchester County …

Hydrosocial Ocean Commons: Offshore Wind Energy In Oregon, Bryce Ashlyn Sprauer

Dissertations and Theses

The ocean has been culturally and legally conceptualized as a commons, a space of subsistence inherited by all. Enclosure or privatization creates overlapping jurisdictions of ocean space. The ocean is also the world's most significant carbon capture, absorbing billions of tons of anthropogenic carbon dioxide since the Industrial Revolution. Now, the ocean offers an additional opportunity to decarbonize energy production and reduce greenhouse gas emissions through 'new frontiers' of offshore wind technology; however, this potential is entangled within neoliberalism. Offshore wind is entering a fragmented legal landscape where the social-legal process of ocean jurisdiction remains contested. As the "new frontier" …

Educational Opportunities Of Participatory Gis For Accessibility On A College Campus, Shiya Cao, Heather Rosenfeld, Sarah Susnea

Statistical and Data Sciences: Faculty Publications

The educational benefits of Participatory GIS (PGIS) in geographic higher education have received limited direct attention, often because of the complexities of integrating PGIS into university curricula. While a few exceptions found important educational benefits of PGIS, extant studies focused primarily on the educational benefits for students who worked in the research teams, instead of participants who contributed their local knowledge and perspectives to mapping. Our research aims to understand the educational benefits of PGIS for participants in a campus accessibility mapping project using the modes of experiential learning, positionality, and service learning. Through this, we also provide strategies for …
