Toward An Understanding Of Social Marketing’S Influence On Alcohol-Related Behaviors In College Students: Health Promotion Strategies For College Campuses, Lily K. Richards

Honors Theses

Alcohol use among college students remains a persistent public health concern, influenced by a complex interaction of social, environmental, and behavioral factors. This literature review examines the prevalence of alcohol consumption in college populations, the associated short-term and long-term health consequences, and the role of social norms, peer influence, and environmental context in shaping drinking behaviors. Research consistently demonstrates that alcohol use is deeply embedded within college culture, where normative misperceptions and peer dynamics contribute to increased consumption. (Perkins, 2002; Borsari & Carey, 2001; Hingson et al., 2017). In addition, environmental factors such as alcohol availability and targeted marketing further …


Salt-Dependent Purification Of Green Fluorescent Protein Via Hydrophobic Interaction Chromatography, Katie L. Collins May 2026

Salt-Dependent Purification Of Green Fluorescent Protein Via Hydrophobic Interaction Chromatography, Katie L. Collins

Honors Theses

Green fluorescent protein, GFP, is a widely used fluorescent reporter, and its purification provides a clear model for studying downstream bioprocessing. This thesis investigates how binding-buffer salt strength affects GFP retention and elution during hydrophobic interaction chromatography, HIC, by comparing three conditions (1.0×, 0.8×, and 0.6×). GFP-expressing E. coli were lysed and clarified, and the lysate was purified on HIC columns; collected fractions were evaluated qualitatively under UV illumination to track fluorescence distribution. Results showed a salt-dependent trend in which higher salt improved retention and shifted fluorescence toward later elution fractions, while reduced salt weakened hydrophobic interactions and increased earlier …

The Personality Of Place: Physical Geography And The Shaping Of The Nineteenth-Century German Immigrant Ethnic Identity, Abigail Ward May 2026

The Personality Of Place: Physical Geography And The Shaping Of The Nineteenth-Century German Immigrant Ethnic Identity, Abigail Ward

Honors Theses

In the nineteenth century alone, approximately five million German-speaking immigrants arrived in America. However, the motivations of these individuals for moving to America, far from identical, were nearly as numerous as the individuals themselves. The German ethnic identity in America was not uniform, but the expression of many factors having to do with both the Vaterland and the new land. These factors ranged from the timing of emigration, which was largely influence by religious, political, and economic upheaval in Europe, to each German’s system of values, which dictated the kind of future he saw for himself and therefore where he …


Choosing Death: The Moral Legitimacy Of Voluntary Active Euthanasia, Emma Rougeou May 2026

Choosing Death: The Moral Legitimacy Of Voluntary Active Euthanasia, Emma Rougeou

Honors Theses

During the last three decades, the issue of physician assisted suicide has captivated the interest of private citizens and state legislatures. Thinking about the matter of end-of-life concerns, particularly surrounding euthanasian (practices that hasten the deaths of suffering terminally ill people) have shifted. Views of private citizens and state-level legislation reflects a “slow shift to more permissive attitudes” (Cohen et al., 2012). Meanwhile, as recently as March 2026, state legislators in conjunction with the NY State Governor, passed a bill legalizing medical aid in dying for terminally ill patients. This thesis is intended to thoughtfully contribute to meaningful discourse on …

The increased use of QACs has further led to an increase in antimicrobial-resistant bacteria, making the synthesis of novel antibacterial compounds vital to combat this growing threat. Recent advances in boronium salts offer a unique alternative to address these adverse effects. …


Spectral Characterization Of Colorectal Cancer Using Excitation-Scanning Hyperspectral Imaging, Natalie Hadad May 2026

Spectral Characterization Of Colorectal Cancer Using Excitation-Scanning Hyperspectral Imaging, Natalie Hadad

Honors Theses

Colorectal cancer is one of the most common and deadly cancers worldwide, with a lifetime risk of approximately one in twenty-three for men and one in twenty-five for women. Although early detection significantly improves survival, current diagnostic approaches such as tissue biopsy are invasive, reliant on subjective interpretation, have extended turnaround times, and risk missing flat or depressed lesions that are more difficult to detect than raised polyps. These limitations highlight the need for objective, minimally invasive technologies capable of detecting early tissue changes. This study investigates excitation-scanning hyperspectral imaging (Ex-HSI) as a label-free optical approach for identifying colorectal cancer–associated …


Developing A Protocol For Non-Cellular Transplantation Of Donor Mitochondria Into Recipient Cells, Andrew Parton May 2026

Developing A Protocol For Non-Cellular Transplantation Of Donor Mitochondria Into Recipient Cells, Andrew Parton

Honors Theses

Tumor innervation has emerged as a critical feature of cancer progression, with increased nerve density correlating with enhanced aggressiveness, metastatic dissemination, and poor clinical outcome. However, the functional contribution of neurons to tumor biology remains incompletely defined. We recently identified the intercellular transfer of mitochondria from neurons to cancer cells as a mechanism that promotes tumor progression. We therefore hypothesized that disruption of this transfer could attenuate tumor aggressivity. To directly investigate this process, we developed an approach to isolate mitochondria from donor cells and transplant them into recipient cancer cells independently of canonical cell-cell interactions. Transferred mitochondria were tracked …

The Oncoming Light: An Experiential Approach To Psychological Exposition Through Dialogue-Driven Narrative, Benjamin G. Dewitt May 2026

The Oncoming Light: An Experiential Approach To Psychological Exposition Through Dialogue-Driven Narrative, Benjamin G. Dewitt

Honors Theses

Narrative is a lens through which we understand ourselves, our histories, our futures, and our ties to those around us. Narrative form has undergone vast transformations over time, and in the case of “postmodern” literature, pushes the boundaries of form into the experimental, questioning the truth of knowledge itself. While these experimental works can give rise to uniquely powerful emotional experiences, some components of narrative, when abandoned, may only hinder the immersion of the reader. This thesis evaluates several experimental, dialogue-driven narrative works against these components: linguistic, literal, emotional, and intellectual significance, in a hierarchy of importance as proposed by …


Synthesis Of Novel 1,2,3-Triarylnaphthalenes Via Intermolecular Dehydro-Diels-Alder Reaction, Ethan C. Dailey May 2026

Synthesis Of Novel 1,2,3-Triarylnaphthalenes Via Intermolecular Dehydro-Diels-Alder Reaction, Ethan C. Dailey

Honors Theses

The photo-dehydro-Diels–Alder (PDDA) reaction is a useful method for the construction of substituted naphthalene derivatives from acyclic precursors. While intramolecular variants of this transformation are well established, intermolecular PDDA reactions remain rare due to challenges associated with controlling reactivity under photochemical conditions. Previous studies suggest that electron-withdrawing substituents can promote intermolecular cycloaddition by increasing alkyne polarization and stabilizing reactive intermediates. In this work, the effect of enhanced electron-withdrawing character on intermolecular PDDA reactivity was investigated through the incorporation of a 2,3,5,6-tetrafluoropyridinyl substituent. Corresponding alkyne substrates were synthesized and subjected to photochemical conditions, resulting in the formation of 1,2,3-triarylnaphthalene products. The …

Creative Nonfiction Essays, Colby S. Langley May 2026

Creative Nonfiction Essays, Colby S. Langley

Honors Theses

To write about the present with any authority requires a keen eye for the past. To write from our lives into meaningful creative nonfiction requires a firm understanding that experience is the composite of life experience blending into the current moment. The writing is then drawn irreversibly towards emotion: indulgent and oppressive. The extremity of emotion dictates the difficulty of transcribing the experience onto the page, and violence is a source of both extreme emotion and experience. It is important to note that I am primarily considering personal violence for this essay, while societal and institutional violence have their own …
