Development Of Blue And Near-Uv Iii-Nitride Laser Diodes, Matthew Seitz

Theses

III-Nitrides show tremendous promise for a wide range of laser diodes and other optoelectronics devices. The wide range of emission wavelengths possible makes these devices ideal candidates for a wide range of applications. Despite this, several challenges remain unsolved, limiting the efficiency and output power from III-Nitride optoelectronics. Three of the most significant remaining challenges surround the formation of low resistance ohmic electrical contacts, poor p-type doping of III-Nitride crystals as well, and the fabrication of the smooth, mirror facets needed for optical feedback and laser operation. Inefficient dopant activation leads to poor conductivity and increased electrical resistance due to …

Underwater Obstacle Detection Using Ground-Penetrating Radar And Ar, Anonymous

Defensive Publications Series

When off-road vehicles engage in water wading, the environment often contains high concentrations of suspended sediments (mud, silt, sand) that render the water entirely opaque. This completely obscures the underlying sub-surface topography and potential hazards, such as rocks or sinkholes. While current Advanced Driver-Assistance Systems (ADAS) are designed for standard road environments, optical cameras and LiDAR are face physical limitations when attempting to penetrate turbid or opaque water. Standard automotive radar (e.g., 77 GHz) operates at high frequencies that cannot penetrate dense, conductive liquid mediums. Furthermore, ultrasonic sensors only measure the vertical distance to the water's surface and lack forward-looking …

Meningioma Detection From Mri: A Comparative Study Of Deep Learning Models, A. H. Doha, Sandi Jennifer, Fatima Alabdaly

AUIQ Complementary Biological System

This study compares several deep learning models including DenseNet20, CNN, ResNet50, VGG19, EfficientNet-B3, MobileNetV2, NASNetMobile, Xception to automatically classify brain meningiomas from MRI scans. A public dataset was used to evaluate the proposed model. All models were trained, validated, and tested on this dataset. Because meningiomas are common and manual reads, the goal is to speed and standardize diagnosis. Our main contribution is pairing a high-accuracy classifier with deep learning models. Among all models, DenseNet201 performed best, reaching 0.991% accuracy and reliably separating tumorous from non-tumorous MRIs. Future work will expand the dataset and incorporate stronger segmentation to further boost …

Hand Mapping: Our Sexual Health Is (Not) In Our Hands, Laura L. Ellingson

Feminist Pedagogy

This Original Teaching Activity introduces hand mapping, an assignment based on the body mapping method, in the context of a communication and gender studies course. Hand mapping can be adapted to interpersonal, organizational, intercultural, and media courses that address identities, intersectionality, communication, culture, and power in different contexts and mediums. Students outline their hands on paper and artfully embellish them as a visual representation of important takeaways or lessons they learned in the course in response to the prompt, “Our sexual health is (not) in our hands.” Students write an “artist’s statement” explaining meanings of color, symbolism, and design.

Beyond The Prompt: Coding The Magis In The Age Of Ai, Vanessa Rotondo

Jesuit Higher Education: A Journal

As a scholar-practitioner in Jesuit higher education, I’ve witnessed how generative AI is not merely a tool students use—it’s a formative force that shapes how they reflect, imagine, and even pray. Drawing on the Catholic imagination, Ignatian pedagogy, and sociological frameworks like liquid modernity, I argue that Jesuit institutions must respond not just technologically and reactively, but actively anticipate methods of integrating AI both theologically and pedagogically. I introduce the concept of Imaginative Intelligence as a formative goal—an embodied, sacramental way of knowing that invites depth, wonder, and resistance to automation. This is not a call to reject AI, but …

Ignatian Pedagogy For Engaged, Reflective, And Inclusive Learning: New Insights On A Treasured Tradition, Jennifer Tilghman-Havens, Jennifer Loertscher, David Green, Kerry S. Von Esch

Jesuit Higher Education: A Journal

Ignatian pedagogy is the philosophy and methodology for teaching and learning that evolved from the wisdom accumulated from 500 years of Jesuit education. The Ignatian approach views education as a collaborative process that transforms students and teachers, preparing them for moral and ethical action in the world. While the core values of Jesuit education have remained constant, the changing demographics within our Jesuit communities and among the faculty and staff of our institutions offer an opportunity to celebrate its many intersections with peer-reviewed research on effective pedagogical approaches that center students and foster justice, diversity, equity, and inclusion. In this …

“Cool People Doing Good Work”: A Rights-Based, Relational Model For Research, Teaching, And Outreach Rooted In Urban Settings, Saúl López, Gabriel Velez, Melissa Gibson, Robert Smith

Jesuit Higher Education: A Journal

Urban Catholic institutions of higher education are being challenged to do more when it comes to working with communities that surround them at the same time as they face multiple external pressure and must clearly define the value of their mission. In this article, we present a model for community-engaged practices that emerge from the ground up to move these institutions more in line with Catholic Social Teaching. “Cool People Doing Good Work” is an adaptable model centered around relationship building and authentic engagement with local experts, stakeholders, and community members that then builds to institutional change. This model places …

Faculty And Staff Formation In Jesuit Higher Education: The Scholarship And Art Of Accompaniment, Belle Liang, Maria Gregoire, Elisa Liang

Jesuit Higher Education: A Journal

This study examines the formative impact of selected faculty and staff formation initiatives offered at Boston College, with particular attention to those shaped by Ignatian spirituality. Drawing on qualitative survey data from 134 participants, the analysis identifies interrelated conditions through which formation is experienced as a coherent process rather than a set of discrete programs. Across initiatives, renewal and vocational clarity were most often described through four conditions: People, Pause, Place, and Purpose, understood here as the alignment of values, commitments, and lived practice. Presence emerged as the relational medium through which People, Pause, Place, and Purpose became formative. Presence …

Integral Education, Institutional Solidarity: A Response To Arturo Sosa’S 2025 Iaju Address, Paul L. Lynch

Jesuit Higher Education: A Journal

During the 2025 meeting of the International Association of Jesuit Universities (IAJU) at the Pontifica Universidad Javeriana in Bogotá, Colombia, Jesuit Superior General Arturo Sosa offered the keynote address, “The Jesuit University: Witness to Hope, Creative and Dialogical Presence.” He urged the global university apostolate to respond to our common challenges: the climate crisis, political reactionism, institutional mistrust, and economic inequality. The Jesuit university, he insisted, must reimagine itself in order to respond to these threats. But the precise manner in which Jesuit universities should respond must still be articulated. This essay begins that project. It opens with an analysis …

Forming Physicians For Others: The Identity Of The Jesuit Catholic Medical School, John Hardt, David G. De Marco Sj

Jesuit Higher Education: A Journal

Forming Physicians for Others: The Identity of the Jesuit Catholic Medical School

The Jesuit medical school accepts a widely-acknowledged telos: the preparation of the medical student to offer excellent patient care. It pursues this telos, however, through the distinctiveness of Ignatian formation, which finds expression in each domain of undergraduate medical education. This formative commitment, oriented toward and witnessing to an appreciation of the unconditional worth of the human being, may empower a subset of medical students—who are engaged by a life of faith and open to the transcendent invitation of their lives—to experience an even more fundamental transformation—one that …

Documenting Patterns Of Spring And Autumn Bird Bigration At Phillips Tract Research Area, A Stopover Site In The American Midwest, Janice K. Enos, Michael R. Avara, Tara A. Beveroth

North American Bird Bander

Stopover habitat, which is used by birds during migration to rest and refuel, is scarce in the American Midwest due to intensive agriculture. Protected woodlots and other small parcels of habitat do exist in the landscape, and may be important for migratory birds to utilize as stopover sites. Here, using mist netting techniques, we documented abundance and age specific patterns of spring and autumn migration at Phillips Tract Research Area, a protected parcel of land comprised of woodlots and mixed grassland plots. We found that 69 migratory species use this site as stopover habitat, and the most common (n ≥ …
