Something To Say: Nativism, Prohibition, And The Loss Of Political Alignment In Davenport, Iowa’S German-American Community 1848-1922, Clayton R. Schuler Dec 2025

Something To Say: Nativism, Prohibition, And The Loss Of Political Alignment In Davenport, Iowa’S German-American Community 1848-1922, Clayton R. Schuler

Graduate Masters Theses

This thesis ends with the municipal elections of 1920 in Davenport, Iowa. Amid the First Red Scare, the Socialist Party was swept into power. The party won under inauspicious national conditions thanks in part to a successful campaign on local concerns; the party had something to say. An examination of the years prior to the election, however, reveals that other factors contributed to political unalignment for the city’s large German descended population. Frustrated with Republican and Democratic parties that seemed to have no place for them, these voters had something to say as well. Ultimately the opportunity that this unalignment …


Shaping The Landscape: Analyzing Enclosure Types, Farm Productivity, And Resource Use In Viking Age And Medieval Iceland, Chiara M. Torrini Dec 2025

Shaping The Landscape: Analyzing Enclosure Types, Farm Productivity, And Resource Use In Viking Age And Medieval Iceland, Chiara M. Torrini

Graduate Masters Theses

Enclosure walls, constructed during the Viking Age and Medieval periods, were a common feature of early Icelandic agropastoral farmstead infrastructure. These walls divided the landscape and created discrete areas, often protecting grass grown in homefields. Harvesting grass for fodder was essential to support livestock, especially cattle, through the winter. Enclosure walls were built with various combinations of turf, stone, and grass sod, which were generally cut, gathered, or excavated close to the wall’s location. Data was collected for this project and combined with substantial previous archaeological work, which all take advantage of common volcanic tephra layers (including Hekla AD 1104), …


Frailty, Home Accessibility, And Falls In Later Life, Bonnie Albright Dec 2025

Frailty, Home Accessibility, And Falls In Later Life, Bonnie Albright

Graduate Doctoral Dissertations

As more people remain in their homes as they age, the risk of living at home with frailty and reduced function increases, which may also increase the risk for falls in the home. The scientific literature shows that frail people are more likely to experience falls, which leads to many negative outcomes, such as hospitalization, placement in a skilled nursing facility, and even death. The preference to age-in-place (AIP) is more likely to be met if older people live in accessible housing. Accessible homes may mitigate the risk for falls and promote AIP, especially among frail older people.

While there …

Shifting Views, Shaping Outcomes: Exploring Relations Between Educators’ Neurodiversity-Affirming Perceptions And Their Autistic Students’ School Experiences, Josh Yen-Ho Chou

Graduate Masters Theses

School environments frequently serve as a source of socialization but also stigma and socioemotional distress for autistic students. Against this backdrop, teachers can be crucial sources of neurodiversity-affirming views and support. Teachers’ perceptions of students can also shape the quality of their relationships with students and students’ emotional and behavioral adjustment in school. This study focused on understanding how general education teachers perceive autistic students and how these perceptions shape their students’ school experiences. This study sought to investigate the degree to which teachers endorsed three dimensions of neurodiversity-affirming perceptions of their autistic students: (a) strength/deficit-based, (b) holistic/reductionist, and (c) …

Early Childhood Educators' Experiences With Autistic Students: A Qualitative Study Of Challenges And Strategies, Sarah Yang Dec 2025

Early Childhood Educators' Experiences With Autistic Students: A Qualitative Study Of Challenges And Strategies, Sarah Yang

Graduate Masters Theses

Early childhood education is a vital early learning context for children ages 2-5 years old, encompassing some of their most formative years of life. Autistic children, however, are expelled from early childhood education programs at disproportionately high rates—a troubling trend that points to a broader picture of how early education environments lack the support and structure that young autistic children need to succeed. Early childhood educators (ECEs) are fundamental in shaping these early education environments and autistic children’s experiences within them. However, while most ECEs want to include autistic children in their classrooms, past research indicates they feel like they …

External Debt And Economic Growth In Sub-Saharan African Hipcs: Linear And Nonlinear Dynamics, Swaliki Kisige Isabirye, John Mutenyo, Oryema John Bosco

Tanzanian Economic Review

Abstract

Economic growth in Highly Indebted Poor Countries (HIPCs) in Sub-Saharan Africa remains heavily influenced by external financing conditions, making the role of external public debt a critical empirical and policy issue. Governments in the region depend on external borrowing to supplement limited domestic resources, yet the extent to which such debt supports or constrains economic growth is still contested. This study therefore examines the linear and nonlinear impact of external public debt on economic growth using a panel of 20 HIPCs covering the period 2000-2024. Employing the Pooled Mean Group (PMG) estimator within a dynamic ARDL framework, the analysis …

This study uses data from the 2022 Tanzania Demographic and Health Survey (TDHS) and applies logit and Tobit models to investigate the relationships between women’s empowerment, FGM/C, and domestic violence. The results indicate that approximately 3 percent of women had undergone FGM/C, while 44 percent had experienced domestic violence. Women’s educational attainment and control over land are also important factors associated with the prevalence of FGM/C. The findings further show a strong relationship between women’s autonomy and their exposure to domestic violence, particularly in relation …


Exporting And Productivity: Evidence From Firm-Level Data In Tanzania, Josephat J. Hongoli, Vincent Leyaro Dec 2025

Exporting And Productivity: Evidence From Firm-Level Data In Tanzania, Josephat J. Hongoli, Vincent Leyaro

Tanzanian Economic Review

Using firm-level data (2006 – 2023), this paper examines the interactions between export behavior and productivity among manufacturing firms in Tanzania.  Specifically, the study tests the hypothesis that more productive firms self-select into export markets and benefit from global markets through learning-by-exporting and economies of scale. The study employs a two-step procedure to estimate firm-level productivity and compares exporting firms with non-exporting firms, controlling for observable heterogeneity. The findings of the study reveal a high and significant productivity premium of approximately 32 percent, which is consistent with the existing empirical literature. The results remain robust even when considering partial productivity …

The Role Of Fuzzy Logic In Cost-Volume-Profit Analysis, Ahmed Imad Abed Al-Atabe, Mohammed Wafi Abbas Al-Shammar

Muthanna Journal of Administrative and Economics Sciences

Cost-volume-profit analysis (CVP) is one of the most important basic tools in management accounting. It enables understanding the relationship between three key elements: costs, volume, and profit level. The problem with this research is that this type of analysis, in its traditional form, uses clear and fixed data, such as the variable cost per unit, total fixed costs, selling price, or sales volume, which can be accurately determined. However, these assumptions do not accurately reflect practical reality, which is often characterized by uncertainty and fluctuations. The research aims to utilize an artificial intelligence tool, fuzzy logic, as a more flexible …

The Filipino teleserye, known for its social realism, offers insights into its viewers’ lives but often presents limited and stereotyped portrayals of LGBTQI+ individuals, including queer women, due to heteronormativity. Fanfiction, specifically slash fiction, resists this by reimagining heteronormative narratives from a queer angle. Despite digital media advancements, Philippine research has yet to analyze fan-led queer representation on digital storytelling platforms, such as TikTok. Hence, following similar research by McGorry (2022), this study purposively sampled fifty sapphic TikTok fan edits of the teleserye Darna (2022) to examine how Vadengs, fans of protagonists Narda Custodio (Darna) and Regina Vanguardia (Valentina), reimagined …
