Evaluating The Effectiveness Of Relationship Education For Latino Adolescents, Joshua J. Turner, Esra Şahin, Kay Bradford, Brian J. Higginbotham

Journal of Human Sciences and Extension

Adolescent romantic relationships are often characterized as exploratory and fleeting; however, they have lasting impacts on individual well-being and relationship quality during and beyond adolescence, shaping future relationship expectations and quality (Collins, 2003; Madsen & Collins, 2011). Adolescent relationship education is an important programmatic feature under the broader umbrella of family life education (Simpson et al., 2018). Previous evaluative studies document positive outcomes in educating adolescents on how to build and recognize healthy relationships (Bradford et al., 2023; Kerpelman et al., 2010); however, research remains limited in addressing potential benefits for adolescents from historically underrepresented groups. This study addresses this …

Power, Interests, And Maternal Health Care: A Political Economy Analysis Of Service Delivery Redesign In Kenya, Jacinta Nzinga, Easter Olwanda, Kennedy Opondo, Hillary Kimutai, Jan Cooper, Brian Arwah, Benjamin Tsofa, Edwine Barasa, Kevin Croke

Institute for Human Development, East Africa

The maternal and newborn health (MNH) service delivery redesign (SDR) in Kakamega County, Kenya, represents the country's first system-level reorganization of MNH services. The reform aimed to improve care quality and reduce mortality by centralizing delivery services at designated hubs. Using a political economy lens, we examined how ideology, political dynamics, and institutional structures shaped the agenda-setting, adoption, implementation, and sustainability of SDR. We drew on data from document reviews, stakeholder analysis, semi-structured interviews, and non-participant observation to assess the structural, contextual, and institutional factors influencing the reform. Ambiguity around SDR's purpose contributed to the community's uncertain engagement characterized by …

Evidence Based Project: Japanese Immigrant Elderly Couples In The Midwest, Isabel Anderson

Student Projects

This paper examined the unique needs and challenges of Japanese immigrant elderly couples living in the rural Midwest of the United States through the lens of systemic family therapy. The focus family consisted of an elderly husband showing early signs of dementia and a wife who recognized the necessity of transitioning to independent living. Their adult daughter and son-in-law’s involvement intensified intergenerational tension, as traditional cultural norms granted the husband decision-making authority. The study provided a statistical overview of Japanese immigrant families in the U.S., highlighting aging trends, linguistic barriers, and geographic dispersion. Common psychosocial and systemic issues such as …

Firms Heterogeneity In Indonesia’S Manufacturing And Services Sectors, Rizki Nauli Siregar

Economics and Finance in Indonesia

Firm heterogeneity is the building block of modern trade theories. One of its important implications is that comparative advantage is driven by firm productivity, rather than sector differences across countries. Despite the prevalence of this framework, there has not been any systematic documentation on firm heterogeneity in Indonesia’s man ufacturing and services firms. Using the World Bank Enterprise Survey (WBES) data for Indonesia in 2015 and 2023, we confirm that there is firm heterogeneity in the form of size and productivity dispersion in both of the economy’s manufacturing and services sectors. We also find no strong association between size and …

Evaluating The Preparedness Of Local Zoning Regulations For Flood Risk Reduction In The Most Affected Local Jurisdictions In Nebraska, Md Asaduzzaman Noor

Community and Regional Planning Program: Theses

Flooding has profound social, economic, and environmental impacts on local communities, and zoning plays a critical role in mitigating these risks. The 2019 Nebraska floods, among the most severe in the state’s history, highlighted the urgent need to strengthen local preparedness and mitigation strategies. This study assesses the extent to which local zoning regulations in Nebraska’s most affected jurisdiction, including rural areas, address flood risk reduction. A systematic review of 117 zoning ordinances from counties, cities, towns, and villages, we applied a structured analytical framework encompassing regulatory and permitting policies, voluntary and incentive-based measures, and nature-based solutions. The results show …

Flood Resilience Through Working-Land Conservation: Assessment Of Wetland Inundation Dynamics Across Wrp, Wma, Wpa, Padus And Crp Lands In Nebraska (2018–2024), Pranjay Joshi

Community and Regional Planning Program: Theses

This study first confirms whether Nebraska’s wetlands are still functioning hydrologically in ways that reduce flood impacts. Wetlands are known to lessen flood damage by storing water, slowing runoff, and moderating peak flows, but these benefits depend on the wetlands’ ability to maintain inundation and saturation through time. Many wetlands across the state have undergone drainage, hydrologic alteration, or isolation from surrounding watersheds, raising uncertainty about their present-day functioning. Using seven years of Sentinel-2 imagery processed in Google Earth Engine, this research establishes a clear, long-term record of inundation patterns across thousands of wetland parcels. This analysis verifies which wetlands …

U.S. Military Veterans And Socioeconomic Opportunities: A Financial Lens On National Public Service, Corri Zoli, Linda Euto, Rosalinda Maury

The Lender Center for Social Justice

This brief offers policy-relevant insights into how military service is an important lever for socioeconomic opportunity and social mobility in the United States. Drawing on the social science literature and recent data from federal sources, this brief focuses on the many financial advantages that result from service, whether due to standardized military pay rates, military networks, or military and veterans’ benefits, from the GI Bill to housing allowances. Such financial advantages from service may also reduce socioeconomic disparities and create economic opportunities for military service members, from building intergenerational wealth to becoming homeowners, including for underrepresented minority service members.

Israeli Hasbara And The Nba’S Palestine Exception: The Impossibility Of Capitalist “Social Justice”, Chen Chen, Anthony J. Weems, Roc Rochon, Daniel Sailofsky

Sport Management Collection

Sport is a notable site for the Israeli state in its hasbara (public diplomacy, or “explaining”) effort that seeks to normalize the conditions of ethnic cleansing, illegal settlement, and apartheid practices in historic and occupied Palestine. Against the backdrop of the genocide in Gaza and the lack of international sport sanctions against Israeli teams, this paper maps several hasbara activities/attempts featuring the National Basketball Association (NBA) in the last decade. This is a worthwhile case, not least because of the NBA’s self-branding as a socially “progressive” league composed of a primarily Black/African American athletic workforce. Two major observations are made: …

Linking Climate And Demography To Predict Population Dynamics And Persistence Under Global Change., Jennifer L. Williams, Amy L. Angert, Aldo Compagnoni, Ali Campbell, Megan L. Demarche, Margaret E K Evans, Joshua C. Fowler, Amy M. Iler, Jenna A. Loesberg, Allison M. Louthan, Scott W. Nordstrom, Multiple Additional Authors

Publications, Reports and Presentations

Predicting the effects of climate change on plant and animal populations is an urgent challenge for understanding the fate of biodiversity under global change. At the surface, quantifying how climate drives the vital rates that underlie population dynamics appears simple, yet many decisions are required to connect climate to demographic data. Competing approaches have emerged in the literature with little consensus around best practices. Here we provide a practical guide for how to best link vital rates to climate for the purposes of inference and projection of population dynamics. We first describe the sources of demographic and climate data underlying …

A Big Data Approach To Mitigating The Maup In Measuring Excess Commuting, Cehong Luo, Yujie Hu, Fahui Wang

Faculty Publications

Excess commuting, defined as the inefficiency resulting from spatial mismatches between residential and employment locations, poses significant challenges for urban planning and transportation systems. This study uses big data from individual vehicle trips collected in Tampa, Florida, to quantify excess commuting more accurately than traditional zonal approaches. Through the application of Linear Programming (LP) and Integer Linear Programming (ILP) models, this research measures minimum and actual commuting patterns across different spatial scales—census tract, block group, and individual trip levels. The findings reveal a clear scale effect associated with the Modifiable Areal Unit Problem (MAUP), as smaller spatial units consistently yield …

Rural Mental Health Challenges: Addressing Community-Specific Needs Of Rural Mississippians, Mary Marshall Waller, Mary Nelson Robertson, Holli H. Seitz, Michael R. Nadorff, David R. Buys

Journal of Human Sciences and Extension

America’s mental health crisis uniquely impacts rural areas. Challenges surrounding intention and accessibility to engage in mental health-fostering behaviors exacerbate disparities in rural mental healthcare. In this study, Cooperative Extension personnel assess rural Mississippians’ intention to engage in mental health-fostering behaviors, accessibility to mental health-fostering behaviors, and helpfulness of increased access to resources for mental health challenges to determine if relationships exist between these variables. Rural Mississippi adults were recruited via an online survey panel to complete a 147-item web-based questionnaire (n = 274). Findings suggest rural adults’ intention to engage in mental health-fostering behaviors favored connecting with family and …

Rapid Decline And Mortality Of A Pleistocene-Aged Forest Now Submerged In The Northern Gulf Of Mexico, Usa, Grant L. Harley, Kristine L. Delong, Marcus Lofverstrom, Carl Andy Reese, Ellen V. Bergan, Samuel J. Bentley, Kehui Xu, Kelli Moran, Karen E. King, Alicia Caporaso

Faculty Publications

The Gulf and Atlantic Coastal Plains of the southern United States are characterized by a wide continental shelf that was subaerially exposed for ca. 80,000 years during glacial-interval marine regressions and transgressions. Given their present submergence, little is known about the vegetation dynamics, particularly at annual time scales, of these formerly terrestrial sites due to erosional processes associated with marine transgressions. Here, we present an annually resolved and well-replicated 489-year tree-ring chronology from macrobotanical specimens—anatomically identified as Taxodium distichum (L.) Rich.—collected in situ from a recently exposed submerged forest in 18 m water depth in the northern Gulf of Mexico. …

Rainfall-Runoff Modelling In An Indonesian Humid Tropical Area Using Satellite-Based Precipitation Products, Noordiah Helda

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

This dissertation explores three rainfall-runoff models in the humid tropical regions of Indonesia using satellite-based precipitation products (SBPPs) and develops integrated machine-learning modeling frameworks. Several ground-based observations from BMKG (Badan Meteorologi, Klimatologi, dan Geofisika (also known as the Indonesian Agency for Meteorology, Climatology, and Geophysics)) stations across Indonesia (133−165 stations) are compared and evaluated against satellite products, indicating that GPM performs well, with R-squared values ranging from 0.54 to 0.76 and correlation coefficients ranging from 0.45 to 0.69, respectively.

Global, Continental, And Local Scale Paleoenvironmental Reconstruction Methods For Interpreting The History Of Miocene North America And The Great Plains, Willow Hue Nguy

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

The Miocene of North America is characterized by dynamic changes in herbivore communities, habitat composition, and global climate. Long-term cooling and drying trends influenced large changes in floral and faunal communities. The Great Plains, North America shifted from closed-canopy biomes to open-canopy biomes with C3-grasses to biomes with C4-grasses. This shift affected the herbivore communities as browsing-adapted ungulates were replaced by grazing-adapted ungulates. Much focus has centered on the Great Plains, so it is not well understood how the changes in biomes compare to other regions of North America. The models used for vegetation density indicate open-canopy biomes since at …

Public Perceptions Of Leadership Effectiveness In Ethiopia Over The Last Decade, Fikadu Reta Alemayehu

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

Ethiopia is one of the largest countries in Africa, with a fast-growing economy, rich history, diverse agroecology, more than 70 languages, and a population exceeding 130 million. However, the country continues to face serious internal conflict, high malnutrition, and economic hardship, while the study of leadership effectiveness remains limited and lacks consistent longitudinal research. To help fill this gap, this study examined how public perceptions of leadership effectiveness and development outcomes changed in Ethiopia between 2013 and 2023, using Afrobarometer survey data. The analysis explored how citizens’ views about governance, wellbeing, and access to services evolved during a decade of …

Where Does The Belt Belong? Examining If The Indiana Southern Baptist Convention Belongs In America's "Bible Belt", Abigail N. Fulton

Undergraduate Honors Thesis Collection

America is known for its Bible Belt, a region known for conservative, fundamentalist Protestantism in the southeast portion of the United States. Though this conservative culture is often associated with the south and their history of conservative politics and racial discrimination, there lies a question of if the Bible Belt is geographically limited or dependent more on culture, history, and the politics within this setting. The Indiana Southern Baptist Convention holds a highly conservative viewpoint on Christian religion, similarly to the southeast portion of the U.S., as well as a controversial history with racism and politics that is linked to …

Embodied Overcrowding And Sensory Tensions: A Carceral Autoethnography Of Philippine Jails, Dwayne Antojado

Ateneo School of Government Publications

In this paper, I undertake a sensorially oriented autoethnography of two Philippine jails, illuminating the visceral textures of carceral life that conventional sociological or criminological discourses often overlook. Drawing inspiration from Jewkes and Young's (2021) examination of Kyoto Prison, I foreground the overlapping realms of sight, sound, smell, and touch, arguing that incarceration is inherently a profoundly embodied phenomenon. By weaving personal reflections, field observations, and broader scholarly insights, I reveal how overcrowded dormitories, suffocating heat, and lingering bodily odours converge to redefine detainees' spatial, temporal, and psychosocial realities in ways rarely captured by quantitative metrics. While mindful of Nelken's …

Teaching Research As An Interdependent Practice: Bringing Alternate Models Into The Scholarly Conversation, Natalia Kapacinskas, Veronica Arellano Douglas

Communications in Information Literacy

The customs and practices of research in academia are often mischaracterized as individualistic pursuits, ignoring the reality that research requires a great deal of collaboration. As teaching librarians, our research instruction often reinforces individualism as a scholarly virtue, even as we simultaneously engage with themes of connection between researchers and their ideas. We propose an approach to teaching research and information literacy grounded in the concept, intention, and practice of interdependence rather than individualism. In doing so, we will call in models of interdependence from critical disability studies, relational-cultural theory, Indigenous Ways of Knowing, and the Cite Black Women movement. …

A Gis Method To Analyze Trajectories Of Gross Changes Through Multiple Temporal Resolutions With An Application To Brazilian Soybean Cultivation, Thomas Mumuni Bilintoh, Robert Gilmore Pontius, Gustavo Oliveira, Julia Shimbo

Geography

Our manuscript presents Trajectory Analysis, which is a novel method to characterize patterns of gross changes during a time series of raster maps. This manuscript is our first article to elaborate on concepts and features of Trajectory Analysis that are necessary to analyze more than two time intervals. The method computes up to eight trajectories and three components of change: Quantity, Exchange, and Alternation. Quantity is the absolute net change between the two time points that bound the temporal extent. Exchange is the additional gross change between the same two time points. Alternation is the additional gross change that derives …

The Librarian Teaching Self-Efficacy Scale, Maoria J. Kirker, David X. Lemmons

Modeling Flood Risks For Small-Scale Coastal Watershed Across Shared Socioeconomic Pathway Scenarios, Sebastian Loschner

Graduate Theses and Dissertations (2019 - present)

Coastal flooding, driven by the mixture of natural processes and human activities such as precipitation, waves, sea level rise, and urbanization, remains a growing concern. While recent flood-risk studies use IPCC's Shared Socioeconomic Pathways with climate projections to assess future flood exposure, smaller coastal watersheds, < 120,000 acres, remain insufficiently studied. Projected sea level rise is expected to intensify these impacts in smaller systems, potentially causing more severe flooding than reported for larger watersheds. To address this gap, this study used the SRH-2D model integrated with Aquaveo's Surface-water Modeling System to simulate flooding in the lower Fish River basin, Alabama. A coastal watershed sensitive to both riverine and tidal influences. Simulations tested different sea levels based on SSP scenarios corresponding to low, moderate, and high emissions for the years 2050 and 2100. Results indicate that the midcentury scenarios remained even in inundation extent and volume, between 9.9-10.4% compared to the 2020 baseline, the latter scenarios had a wider range in results of between 25.9-50.3% compared to the same baseline. Across scenarios, the most vulnerable and inundated areas of the smaller coastal watershed were the narrow points where upstream flow convene with downstream backwater. These findings highlight the need for futuristic location-specific flood mitigation strategies.
