Examination Of Metacognitive Strategies As An Intervention Supporting College Readiness For Students In Large Enrollment Introductory Biology Courses, Angela S. Mohrman

Theses and Dissertations

Students who meet traditional definitions of college readiness based on prior coursework, grades, and standardized test scores often continue to struggle in large-enrollment introductory STEM courses. These struggles are particularly evident in introductory biology, where high cognitive demands, rapid pacing, and content volume require learners to regulate their own studying in ways many students have never been taught. This action research study examined whether sustained, explicit instruction in metacognitive regulation—planning, monitoring, and evaluating learning—could support introductory biology students’ college readiness and learning of biology content.

Using a mixed-methods action research design, the study investigated a 15-week co-curricular metacognitive intervention taken …

Evidence Of Metal-Microcystin Complexation And Its Potential Role In Environmental Fate, Ashley Marie Womer

Theses and Dissertations

Microcystins that enter freshwater systems pose a threat to human health therefore their fate and transport throughout the water column have been intensively studied. While sediment has been regarded as an environmental fate for microcystin (MC), less is known about the molecular mechanisms by which microcystin interacts with the sediment and/or the thermodynamic stability of these interactions. While microcystin has a half-life in lake water on the order of weeks, microcystin adsorbed to sediment can be detected hundreds of years later1-2. Microcystin has been desorbed from these sediments with various EDTA solutions, therefore, work is presented to support the hypothesis …

The Use Of Machine-Learning Interatomic Potentials To Study Bulk Properties Of Aqueous Zn Ion Batteries, Ria Vasdev

Theses and Dissertations

Aqueous Zn-ion batteries (AZIBs) have emerged as a promising energy storage tech- nology owing to their high Coulombic efciency and low environmental impact. However, their practical development is impeded by limited cycling stability, pri- marily caused by parasitic side reactions occurring at the anode surface. These side reactions are strongly infuenced by the bulk solvation structure of Zn-based elec- trolytes, which remains challenging to characterize using conventional experimental techniques. Machine-learning interatomic potentials (MLIPs) provide a powerful computational approach to investigate these systems and can be employed to eluci- date the bulk structural properties of Zn electrolytes.

The Mountains Call: Escaping To Zones Of Seclusion, Alec Lee Parry

Theses and Dissertations

The biographical and thematical overlap between the literature of Austrian authors Ingeborg Bachmann and Thomas Bernhard, and Swiss writers Max Frisch and Fleur Jaeggy, is established in literary scholarship. However, similarities in the role Alpine spaces play in their works remain unaccounted for. The Alps represent a cultural and geographical boundary between linguistic identities and international borders. Protagonists across this dissertation’s three chapters face internal crises, prompting them to move to “zones of seclusion.” Within these “zones of seclusion,” characters spark discussions of collective memory even if they are isolated themselves. These peripheral locations force recollection, often on collective memory, …

The Enchantment And Disenchantment Of The Virgin Mary From Late Middle Ages Through The Reformation, Quentin Jameson

Theses and Dissertations

This thesis analyzes the Virgin Mary’s role in late medieval and early modern high magic, arguing that her presence and absence in magic display cases of enchantment and disenchantment. Starting in the twelfth century, debates on Mary’s immaculate conception and purity gradually reshaped and elevated her status in Latin Christendom. This enabled Mary to be an active agent within magic as a purifier and advocate. However, early modern natural philosophers and leaders of the Reformation removed these divine abilities from Mary, producing a disenchanted Virgin within high forms of magic.

This thesis applies Karen Barad’s concept of intra-activity and continuous …

The Secondary City: Georgetown And The Waccamaw Neck Within A Global Maritime Perspective, 1740-1850, John Paden Wilson

Theses and Dissertations

Georgetown is not and has never been the primary city on the South Carolina coast. Its harbor is shallow and muddy and its urban development lacks the commercial density found in more prominent Atlantic port cities such as New York, Boston, Philadelphia, and Charleston. Despite all indicators to the contrary, this marshy backwater outpost became the second richest port in the United States prior to 1850 through rice and indigo exportation. As a result, the port drew people, goods, and ideas from around the Atlantic. Despite its small size and limited cultural relevance, Georgetown was a regional node for international …

A Tail Of Consumption: Essays On Pet-Person Identities And Their Effects On Consumers, Mackenzie Micheala Volk

Theses and Dissertations

This work examines how exposure to pet-person identities — identifying as a dog person or a cat person — affects consumer behavior. Across two chapters, results show that exposure to dog-person cues increases preferences for bold and conspicuous product features through heightened desire for dominance-based status signaling. Additionally, exposure to cat-person cues activates a cat-person mindset, boosting support for inclusive businesses and policies by increasing minority support and justice sensitivity. Together, these findings suggest that subtle identity cues in the marketplace can meaningfully shape consumer preferences and social attitudes, with implications for how brands position themselves and how policymakers and …
