Assessing Diffusive Gradients In Thin Films Passive Samplers For Pfas Quantitation In Aqueous Systems, Brianna Harris

Graduate Theses and Dissertations

Diffusive gradients in thin-films (DGT) passive samplers are an alternative to grab sampling for quantifying time-weighted average (TWA) concentrations of per- and polyfluoroalkyl substances (PFAS) in aqueous systems. DGTs may enable long-term PFAS site characterization in a more time and cost-effective manner compared to grab sampling, but critical information is lacking in PFAS diffusion coefficient (DGel) uncertainty, PFAS quantitation limits, and environmental impacts on DGT performance. This work provides a thorough evaluation of DGT performance for a suite of 32 PFAS through (i) determining gel-layer PFAS diffusion coefficients and their associated error (i.e., 95 % confidence intervals (CIs)), (ii) assessing …

Application Of The Mattering Model By Generation In The Context Of Teacher Retention In Indiana K-12 Schools, Byron C. Sanders Ii

All-Inclusive List of Electronic Theses and Dissertations

When teachers see their actions as significant and recognize they would be missed if they were gone, they realize the significance of their individual impact (Wilfong & Donlan, 2024). Understanding what matters to teachers is an important factor in the process of teacher retention. This study examined the difference in four generations of Indiana K-12 teachers against the eight elements of mattering identified by Dr. Shelly Wilfong (2021).

Cracking The Hive Code: A Quantitative Examination Of Queen Bee Syndrome Behaviors In K–12 Education, Katie Renee Gordon

All-Inclusive List of Electronic Theses and Dissertations

Queen Bee Syndrome (QBS) has historically been used to describe women who distance themselves from other women and hinder the advancement of female peers (Staines et al., 1974). While early explanations framed QBS as rooted in individual competitiveness, more recent scholarship suggests it may reflect responses to gender discrimination and organizational context (Derks, 2017). In K–12 education, women comprise the majority of the workforce, yet remain underrepresented in upper leadership roles, particularly the superintendency. The purpose of this study was to examine perceptions of Queen Bee Syndrome behaviors among female leaders in K–12 educational settings and to explore how internal …

The Double Desert Dichotomy And Its Political Consequences, Sophie Coker

Political Science

Millions of Americans lack adequate broadband access. While there is a lack of clear consensus of the number of households without broadband services between Federal Communications Commission and independent estimates, one factor is clear: rural communities are disproportionately excluded from adequate broadband coverage. The same areas which lack broadband access find themselves in news deserts, or a community that is no longer covered by daily or nondaily newspapers. Moreover, there is a crossover between the communities underserved by broadband services and the communities lacking local news sources. Double deserts, where lack of broadband and local news access meet, are threats …

Multicultural Nationalism And The Politics Of Belonging In Australia, Grace Mancuso

Political Science

In contemporary political discourse, nationalism and multiculturalism are often stated to be fundamentally opposing forces. With nationalism emphasizing unity and shared identity, and multiculturalism emphasizing cultural diversity and difference. As the world becomes more interconnected and discourse around immigration has become rampant, many nations are looking for a way to unify their currently divided populations. Multicultural nationalism has been called upon by many scholars as a potential solution to growing divisions, especially in countries with high levels of social diversity such as Australia and the United States. However, many politicians and social scientists are skeptical of this notion fearing it …

Preserving The Past: Exploring The Last Frontier's Ecosystem Shifts And Biodiversity Of The Tallgrass Prairies, Gisell Maldonado, Amelia Villaseñor

Anthropology Undergraduate Honors Theses

In North America, grasslands are a cornerstone of the environment. Historically, the tallgrass prairie was expansive and reached from Manitoba in Canada to Texas. Today this unique ecosystem is highly fragmented and reduced, but it remains an important ecosystem for biodiversity and cattle management. While there are many complex ecological interactions in the prairie, recent research shows that large herbivores are vital in maintaining grasslands through grazing and other behaviors that reduce woody encroachment and support nutrient cycling. Here, we examine cow and bison dietary behaviors and connect these to the ecosystem services provided by these large herbivores. In the …

Sacred Spaces In The African Diaspora: Archaeology Of Praise Houses And The Cultural Preservation Of The Gullah/Geechee, Libby C. Holden

Anthropology Undergraduate Honors Theses

Historical archaeology is traditionally defined as the study of remains from past cultures and societies that have supplemental historical evidence, usually in the form of written records, with the rough timeline covering 1500-present.[1] African American archaeology is a relatively new subfield in historical archaeology. The first archaeological investigations focused in African American life occurred in the 1960s by Charles H. Fairbanks, a historical archaeologist of the U.S. Southeast based at the University of Florida.[2] The sudden uptick in interest of plantation archaeology and African American archaeology during this time is likely attributed to the passage of historic preservation …

Primate Craniofacial Trauma And Its Relationship To Socioecological Factors, Kaitlyn Harden R. Harden

Anthropology Undergraduate Honors Theses

Postmortem analysis of the skeleton can reveal patterns of trauma that have accumulated over an individual’s lifetime. Patterns of trauma within a species can also provide key insights into how that species lived and reflect aspects of their socioecology and life history. Research has been conducted often on postcranial trauma, but is rare regarding the craniofacial region and has not been examined broadly across primates. To fully understand patterns of trauma in primates, rates of trauma must be compared and placed into context of a variety of socioecological factors. To do so, I examined hypotheses including that species with higher …

Leveraging The Iron Oxide Archive Of Mineralization, Deformation, And Exhumation Across Geologic Time, Jordan L. Jensen

All Graduate Theses and Dissertations, Fall 2023 to Present

The iron oxide mineral hematite commonly forms from groundwater near Earth’s surface and can preserve a history of fluid flow, fault slip, and landscape evolution. This record can be decoded using (U-Th)/He thermochronology, a dating method based on the temperature-sensitive ingrowth of helium from uranium and thorium decay. Because later heating and natural variation in hematite crystals can produce ambiguous (U-Th)/He results, I integrate dating with tools that reveal differences in hematite chemistry and textures. I apply these techniques to two distinct settings: ancient granitic rocks in Colorado and an active fault zone in the southern San Andreas fault (SSAF) …
