Modeling The Copying Accuracy Of Two-Dimensional Holographic Gratings In Photopolymer Media, Maged Shaban, Dana Mackey, Owen Kearney, Izabela Naydenova

Research Outputs: 2025-Present

Volume holographic gratings are periodic refractive index structures widely used in sensing and photonic devices. This paper develops a modeling and computational framework for predicting the copying accuracy of two-dimensional gratings recorded in photopolymer materials using interference lithography. A previous mathematical model is generalized to describe material transport, polymer growth, and modulation of the refractive index during exposure, enabling, for the first time, a quantitative assessment of copying accuracy in holographic gratings. High-fidelity finite-element simulations were performed for different optical lattices produced by three-beam interference. The results show that the diffusion–polymerization ratio has a strong impact on pattern accuracy, modulation …

The Effect Of Incidental Emotions On Self-Control: An Examination Using A Need-Based Choice Model, Shruti Koley

Business Faculty Publications and Presentations

Purpose – The purpose of this paper is to develop a framework that examines the effects of incidental emotions on choices in self-control dilemmas. The framework predicts that the effect of emotions depends on the hedonic and non-hedonic needs they activate and the extent to which emotional consumers expect the virtuous and gratifying options in the choice dilemma to facilitate these needs (i.e. their instrumentality toward the activated needs). The framework helps develop propositions for the self-control effects of six commonly experienced emotions: happiness, sadness, pride, guilt, anger and anxiety. Design/methodology/approach – The author uses a choice model to develop …

Bridging The Justice Gap: A Comparative Study Of Legal Aid Marketing In Canada, Australia, And The United States, Farah O. Haq

Student Theses and Dissertations

Access to justice remains a central challenge across legal systems, particularly for immigrants and refugees, Indigenous communities, and survivors of domestic violence. While legal aid organizations play a critical role in bridging this gap, their effectiveness increasingly depends on how clearly and compassionately they communicate legal information online to their target audience. This thesis conducts a comparative content analysis of nine nonprofit legal aid organizations in the United States, Canada, and Australia, three countries united by a common law tradition but divided by the communication barriers their communities face, examining 180 social media posts and nine websites through the lens …

The Importance Of Career And Retirement Services For Student Athletes, Vincent R. Giuliano

Masters Projects

There are hundreds of thousands of collegiate student-athletes competing in organized sports in the NCAA. Research shows the different resources that are available to them during their time competing, as well as how sports can open different opportunities for them during their competitive years. However, once this is over, an individual may realize they spent their time becoming an athlete and not enough time on their holistic well-being and professional development due to time constraints, identity engulfment, etc. While institutions do well in nurturing students during their competitive years, they lack in considering the retirement of these student-athletes. This project's …

(Co,Ni,Mn,Cu,Zn)O High-Entropy Oxide Nanotubes As Efficient Bifunctional Electrocatalyst For Oxygen Evolution And Hydrazine Oxidation Reactions, Pan-Yan Chen, Wan-Wan Wu, Heng Bian, Wei-Wei Li, Xin-Sheng Zhao, Lu Wei

Journal of Electrochemistry

High-entropy oxides (HEOs) present significant scientific challenges in both design and synthesis due to their multielement and high-entropy nature, which involves complex combinations of multiple metal cations and oxygen anions, typically arranged in equimolar ratios to achieve structural stability. Herein, one-dimensional (Co,Ni,Mn,Cu,Zn)O high-entropy oxide nanotubes (HEO-NTs) are fabricated by means of a gradient electrospinning strategy with a tailored polyvinyl alcohol (PVA) molecular weight distribution and controlled pyrolysis. Benefiting from the HEO features and the synergistic effect of multicomponent sites, the as-synthesized (Co,Ni,Mn,Cu,Zn)O HEO-NTs exhibit exceptional bifunctional electrocatalytic activity for the oxygen evolution and hydrazine oxidation reactions (OER/HzOR). This study offers …

Social, Economic, And Environmental Sustainability Of Small-Scale Hydroponic Farms, Alexa Genevieve Kaminski

Theses

Controlled environmental agriculture (CEA) is well-positioned to contribute to a more sustainable food system. It has the potential to offset some of the negative impacts of conventional agriculture through its ability to optimize the crop growing environment, locate production closer to population centers, and take advantage of non-arable land. The focus of this dissertation is one type of CEA: the hydroponic container farm (HCF). The HCF grows crops using only water and fertilizer inside a 40-foot shipping container that can be located anywhere in the world. Manufacturers are optimistic about this farm’s abilities, but little research exists that investigates the …

Maryland Reproductive Freedom And The Full Personhood Of Pregnant People, Margaret E. Johnson

All Faculty Scholarship

Pregnant and birthing people are inappropriately criminalized. Such criminalization is for behavior during their pregnancy that would not otherwise be criminalized, including when there was no harm to the later born baby, and for birth outcomes like miscarriages and still births. Law supports criminalization in part because of the historic legal significance given to fetal “viability” as a demarcation between full personhood rights for pregnant people and the encroachment of fetal “personhood” on those rights. Focusing on Maryland’s new constitutional amendment for reproductive freedom, this essay examines how the new amendment offers promise in restoring the full personhood rights for …

The Relationship Between Musical Ability And Perceptual Skills For Speech Motor Learning In Young Adults, Emily Catmull

Theses and Dissertations

Speech motor learning is the multimodal process of acquiring speech sounds. Speech motor learning is trained through speech-language pathologist intervention in individuals across the lifespan. Previous research has explored which factors can influence speech motor learning, such as musical experience or training, which is the subject of this study. Sixty young adult participants (four male, 56 female) were recruited as part of a larger study that examined four possibly influential factors: bilingualism, phonetic knowledge, perceptual skills, and musical experience. Since the adult population has already acquired all the speech sounds in English, learning was measured using nonnative consonant clusters. Participants …

Structure Of Ergosteryl-Aspartate Synthase Reveals How An Entrapped Trna Is Used Like A Prosthetic Swinging Arm In The Synthesis Of Aminoacylated Sterols, Hanako Murayama, Nathaniel Yakobov, Nassira Mahmoudi, Sasha Legrosdidier, Nicolas Fournier, Solène Zuttion, Kanata Matsumoto, Michihiro Nishimura, Jingwei Ji, Bruno Senger, Laurence Huck, Howard Gamper, Yoshiaki Kise, Ralph Kleiner, Mathieu Frechin, Ya-Ming Hou, Hubert Becker, Yuzuru Itoh, Frédéric Fischer, Osamu Nureki

Department of Biochemistry and Molecular Biology Faculty Papers

Ergosteryl-3β-O-L-aspartate synthase (ErdS) catalyzes tRNA-dependent aspartylation of ergosterol, a lipid essential for fungal cell membrane integrity. However, the functional significance of ergosteryl-aspartate and the molecular mechanisms underlying its synthesis remain unclear. Here, we show that ErdS localization is highly dynamic and that Erg-Asp is required for proper hyphal growth, sporulation, and spore germination, and likely influences stress tolerance. The cryo-electron microscopy structure of ErdS revealed an unprecedented sterol-binding pocket. In addition, the structures in complex with a non-hydrolyzable Asp-N-tRNAAsp show a tRNA-guided intramolecular aminoacyl transfer mechanism between two functional domains of the enzyme. The CCA end of tRNAAsp undergoes a …

From Double Absence To Double Presence: Video-Selfie As Empowerment In A Multicultural Italian Classroom, Maria Ranieri, Ilaria Bucciarelli, Giulia Cuozzo

Journal of Media Literacy Education Pre-Prints

This paper examines the video-selfie as a tool for empowerment in multicultural secondary school classrooms. We draw on data from the European ICME project, focusing on a vocational secondary school in Italy, where 17 of 18 first-year students – approximately half of whom had migration backgrounds – produced short videos presenting themselves through personally meaningful objects. Students then participated in a structured reflection activity after watching each other's videos in class. We combine three theoretical frameworks: critical media literacy, identity and self-representation studies, and Mezirow's transformative learning theory. Our argument is that the video selfie empowers in multiple ways: it …

Living With Ai Within The Context Of Higher Education, Terry Jo Smith

i.e.: inquiry in education

This autoethnographic study examines how generative AI has entered higher education, reshaping teachers’ and students’ inner lives, relational practices, and institutional ecologies. Drawing on the author’s embodied experiences within the higher education landscape, the analysis consists of plugging in theory, research, policy, and current events as a means to connect individual experience with broader concepts, events, and structures (Jackson & Mazzei, 2022). The paper maps affective responses such as awe and anxiety, pedagogical tensions such as assessment, transparency, and trust, and political-economic drivers such as capitalism and policy. The study foregrounds methodological reflexivity, arguing that critical autoethnography can surface situated …

Ai-Powered Remixes: Using Generative Ai To Critically Examine Text, Genre, And Language In First Year College Writing, Lauren Anderson, Eric Vandemark

i.e.: inquiry in education

As generative AI tools become embedded in writing instruction, educators face urgent questions about how these technologies encode and reinforce language standardization — particularly for multilingual and multidialectal students. This practitioner reflection describes a series of AI-powered "remix" activities developed and refined in corequisite writing labs. Building on a prior action research study, this paper turns to the pedagogical questions that emerged after the study: how AI tools might be used not as writing shortcuts but as objects of critical inquiry. Drawing on frameworks including critical literacy, plurilingualism, culturally relevant pedagogy, and AI literacy, we describe four remix activity types …

When The Output Looks Like Learning: Tertiary Algorithmicity, Unproductive Success, And The Case For Pedagogical Friction In K–12 Schools, Micah J. Miner

i.e.: inquiry in education

The rapid adoption of generative artificial intelligence in K–12 schools has outpaced educators' capacity to evaluate its effects on learning. This conceptual article argues that the dominant institutional responses treating AI as either an integrity threat or a productivity tool share an unexamined assumption that the fundamental nature of learning remains unchanged. Drawing on Walter Ong's media ecology and extending it through the concept of tertiary algorithmicity, the article offers a theoretical framework for understanding generative AI as a qualitative shift in the symbolic environment of schooling. For the first time, the prevailing communication technology ctively generates symbolic content, enabling …

Making Ai An Intelligent Tool For Our Schools: Using The Perceptions Of Administrators And Teachers In A Midwestern School District To Help Shape Our Educator Preparation Program, John A. Huss

i.e.: inquiry in education

This qualitative practitioner research study explored the attitudes and perceptions of administrators and teachers in a high-performing Midwestern school district regarding the integration of artificial intelligence (AI) in K-12 education. While AI has rapidly emerged as a transformative force in society, its implementation in schools remains inconsistent, with limited policies, training, and usage. Semi-structured interviews with nine educators (three principals and six experienced teachers) revealed widespread interest in AI, but also significant uncertainty and uneven adoption. Educators reported using AI for administrative and instructional tasks, such as grading and resource generation, yet expressed concern over student overreliance and diminished critical …
