Ai-Powered Knowledge Engines As Research Infrastructure For Systematic Knowledge Discovery, Gary Welz

Publications and Research

This paper proposes knowledge engines as a framework for understanding how intelligent systems — both human and artificial — systematically discover, integrate, and generate knowledge. We argue that history’s greatest scientific minds functioned as knowledge engines, processing information through iterative cycles of ingestion, analysis, synthesis, and communication, guided by curiosity and willingness to challenge established beliefs.

We propose a taxonomy of nine integrated capabilities — ingestion, digestion, analysis, calculation, comparison, connection, association, analogy, and multimodal communication — that any serious knowledge engine must combine systematically. The argument is deliberately integrative: achieving ambitious research goals requires orchestrating all nine capabilities within …

Ecological Footprint Assessment, Santina Benincasa

Open Educational Resources

This handout guides students through a structured ecological footprint assessment using the online Footprint Calculator. By following a series of steps—selecting their location, entering detailed lifestyle information, and reviewing personalized results—students evaluate how many planets would be required if everyone lived with their same resource consumption patterns. The activity prompts learners to identify the largest contributors to their footprint, quantify their impact in global hectares, and explore scenario-based changes that could reduce their environmental demand. Through reflection, students consider how everyday human behaviors influence Earth’s productive capacity and resource availability. Overall, the exercise encourages critical thinking about sustainability and personal …

Signal And Substance: Why Methodological Sophistication Fails To Guarantee Inference, Aamir Rashid, Rizwana Rasheed

Publications and Research

Despite increasing analytical sophistication, empirical research in organization studies continues to suffer from fragile inference, uneven theoretical accumulation, and contested credibility. This paper seeks to explain why these problems persist by shifting attention from authors’ methodological choices to the evaluative dynamics of peer review. Adopting a conceptual and theory-analytic approach, the paper theorizes peer review as an inferential gatekeeping system. Drawing on research design, theory evaluation, and philosophy-of-science literatures, this study develops an analytical framework to examine how evaluative routines shape what constitutes empirical rigor during the review process. The analysis identifies five recurring reviewer blind spots: inferential scope inflation, …

The Double Attraction Paradox, Rem Jaen D. Krafft

Publications and Research

The Double Attraction Paradox is a podcast series that teaches adolescents how to navigate attraction through body language, limerence, and mirroring while understanding the psychology behind emotional connection. It is a manuscript that combines personal experience, observations, and research, inspired by Rem Jaen D. Krafft's high school crush. Not only does it provide a guide for teenagers and young adults, but it also encourages readers to better understand attraction, communication, and emotional development. The final chapter examines how peer pressure, traditional high school cliques, fear of rejection, and fear of intimacy may influence societal norms, emotional contagion, and relationship formation …

Ai-Resistant And Ai-Resilient Assessment In Higher Education: A Systematic Review Of Validity-Grounded Strategies, Institutional Frameworks, And Equity Implications, Asrat Genet Amnie

Publications and Research

The emergence of large language models has precipitated a fun damental disruption to higher education assessment. Conventional instruments are susceptible to AI-assisted completion, threatening construct validity across disciplines and institutional contexts. When submitted work reflects AI capability rather than student competency, the inferential chain from performance to qualifica tion is invalidated – a problem of design rather than detection. This systematic review makes two contributions. First, it theorises and grounds the distinction between AI-resistant assessment, which seeks to prevent or impede AI access through containment, and AI-resilient assessment, which assesses genuine human cogni tive performance of intrinsic educational value regardless …

Chi Meta-Project Ecosystem Overview - Spring 2026, David B. Smith

Publications and Research

This paper offers a high-level account of the Center for Holistic Integration’s (CHI) meta-project ecosystem as visualized in the included system map. CHI provides an organizational structure framed around persistent meta-projects that support and extend individual initiatives across curriculum, scholarly and applied research, infrastructure, artistic production, AI development, cultural inquiry, and external partnerships. Rather than presenting the map as a static inventory of projects, the paper examines how its core domains function as living systems through which knowledge, tools, documentation, participants, and collaborations can accumulate over time. It also considers how CHI-mediated connectivity, institutional integration, and external funding allow the …

Assessment Of Information Literacy Instruction In Reference: Applying Vanscoy’S Conceptual And Procedural Framework In Practice, Vanessa Arce

Publications and Research

The instructional aspect of reference work has long been acknowledged, especially in academic libraries. The current RUSA guidelines include helping users develop information literacy as a goal of reference. In this context, investigating the presence and nature of information literacy instruction can be used to assess the quality of reference services. This study applied Amy VanScoy’s conceptual/procedural framework for point-of-need instruction to a sample of chat reference transcripts at Lehman College, City University of New York. One of the assessment’s goals was to determine the prevalence of instruction and type of knowledge addressed in reference interactions. Another goal was to …

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, Teaching - Volume 4, Stephen Demeo

Publications and Research

In Volume 4, the last book of the series, I continue the argument for greater parity between conceptual knowledge—the "what" of science—and methodological knowledge—the "how" of science—but in the context of teacher instruction. To this end, two literature reviews are presented: One on how students build confidence, specifically regarding the reliability or consistency of measurement or results, and the other on scientific uncertainty. Research studies focusing on student misconceptions are summarized and organized from the elementary to the college level. These literature reviews describe invaluable ways for teachers to improve their instruction, while providing examples of experiments that can be …

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, Uncertainty And Error - Volume 3, Stephen Demeo

Publications and Research

Volume 3 explores the essential roles of uncertainty and error in scientific experimentation. It distinguishes between scientific error and scientific uncertainty: Scientific error refers to the difference between an experimental value and an accepted literature value, as well as the difference between data points in an x-y scatter plot and a predicted trendline. Scientific uncertainty, on the other hand, is associated with doubt arising from instrument limitations, variability within a data set, and psychological factors. Human error is set apart as mistakes or blunders, not to be conflated with scientific error.

Of utmost importance to the scientific investigator is the …

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, The X - Volume 1, Stephen Demeo

Publications and Research

In Volume 1, I critique the traditional School Scientific Method—an oversimplified, underdeveloped, and short, stepwise process—and argue for a more authentic, detailed, and rigorous approach to experiment-based scientific inquiry in education. I briefly explain the historical roots of the School Scientific Method, its benefits in increasing the exposure of experimental science to the masses, and its limitations in fostering more authentic scientific thinking and experimental practice.

In place of this traditional and problematic method, I introduce a graphic organizer called sciXpsy to foster both big-picture and detailed scientific thinking. The heuristic combines scientific concepts and methodology with the psychology of …

Laminarin-Loaded Solid-In-Oil Nanodispersion For Enhanced Non-Invasive Transdermal Immunization, Md. Shahin Ekka Sarker, Yoshirou Kawaguchi, Rie C. Wakabayashi, Noriho J. Kamiya, Muhammad Moniruzzaman, Masahiro Goto

Publications and Research

Simple and non-invasive transdermal vaccination is an attractive alternative to conventional injection-based immunization. However, the effectiveness of transdermal vaccines is often constrained by the stratum corneum barrier. Although the use of solid-in-oil (S/O) nanodispersion technology has successfully facilitated skin permeation to induce an immunological response, the antibody titers remain suboptimal. Herein, a dectin-1 selective ligand, laminarin, was used as an immunostimulatory adjuvant to enhance the immune response. S/O nanodispersions loaded with laminarin and ovalbumin (OVA) were systematically developed and characterized in terms of particle size, in vitro OVA release behavior, and skin permeation performance using excised mouse skin. In vivo …

Centering Well-Being And Wholeness: Exploring Racial Battle Fatigue Among Black 3-K To Twelfth-Grade Teachers, Olubunmi Fashusi

Theses and Dissertations

This qualitative case study, with some descriptive statistics, examined Black 3-K through 12th- grade teachers’ experiences with racial battle fatigue (RBF), the psychological and behavioral stress responses they perceived most accurately convey how RBF manifests for them, and the strategies they used to disrupt RBF’s impact. Participants experienced compounded RBF due to advocating for students (i.e., speaking out, supporting, or intervening). Participants’ most perceived psychological stress response to RBF was racism awareness, and most perceived behavioral stress response was spirituality or religion. Participants disrupted the impact of RBF through intrinsic care (i.e., purpose or why, managing emotions, and self-care) and …

New York State Excelsior Scholarship Program: A Post-Implementation Analysis Of Student Success, Eligibility, And Indebtedness – An Intersectional Study Of Black And White Female Students, Marcus I. Richardson

Dissertations, Theses, and Capstone Projects

The New York State (NYS) Excelsior Scholarship Program, introduced in 2017, was designed as a “first-in-the-nation” tuition-free initiative intended to expand college affordability for undergraduate students attending public institutions in New York State. While the program aims to increase access to higher education, its eligibility requirements, particularly the expectation that students complete 30 credits annually through continuous full-time enrollment, may disadvantage students whose academic pathways diverge from traditional enrollment patterns. This study examined the relationship between structural, financial, and academic factors and students’ ability to retain Excelsior Scholarship eligibility at the City University of New York (CUNY). Using institutional data …

Molecular imaging, specifically positron emission tomography (PET), is vital for detecting disease and understanding its biological makeup. The exploitation of radiolabeled antibodies for PET imaging has proven to be indispensable to the field of molecular imaging over the last several decades. The development of radioimmunoconjugates for use in immunoPET has not only allowed for the sensitive, specific, and high-resolution detection of disease, but has also enabled a deeper understanding of the disease biology, ultimately guiding more personalized therapeutic strategies. Most typically, this technology is harnessed for the diagnosis and treatment of cancer, however more recently, the field has explored the …

Mediating Energy And Charge Transfer Dynamics Of Lead Halide Perovskite Nanocrystals Via Surface Chemical Approaches, Aaron S. Malinoski

Dissertations, Theses, and Capstone Projects

Energy and charge transfer are the fundamental mechanisms by which semiconductor nanocrystals interact with their external environment and underpin all light-conversion related applications. Lead halide perovskite nanocrystals (PNCs) are a relatively new class of semiconductor nanocrystals that possess a unique and dynamic surface chemical environment. Investigations into the influence of these surface chemical conditions on the electronic coupling between surface-bound molecular acceptors and the perovskite nanocrystals, and how the surface chemistry can be manipulated, in turn controlling the charge and energy transfer mechanisms, is the focus of this dissertation. Through ligand-shell engineering using commercially available, inexpensive small molecules, the surface …

Algorithmic Problems In Automorphic Orbits Of Free Groups, Siobhan B. O'Connor

Dissertations, Theses, and Capstone Projects

One of the fundamental problems in the field of combinatorial group theory is telling when two group presentations represent isomorphic groups. Since applying a free group automorphism to the set of relators of a presentation gives an isomorphic group, we want to be able to quickly decide when looking at a relator whether a given word can be sent to it via an automorphism. We give a hands-on introduction to the automorphisms of free groups using patterns of colored beads. We show that you can make this decision correctly in constant time on average by looking for "orbit-blocking" words that …

Race And The Enduring Logic Of Exclusion In U.S. Immigration Policy, 1882–2025, Kejda Nikollaj

Dissertations, Theses, and Capstone Projects

This thesis examines how immigration law in the United States has historically functioned as an instrument of racial exclusion and argues that this logic continues to shape contemporary policy and enforcement. Although overtly racist laws such as the Chinese Exclusion Act (1882) or the National Origins Act (1924) have long been repealed, their underlying rationales and structures continue to survive under the modern language of legality, security, and national interest. This study argues that restrictive immigration policies tend to emerge when racial and social insecurities intersect, allowing old hierarchies to be revived under new legal justifications. Through a comparative historical …

Electromagnetic Counterparts To Active Galactic Nucleus Disk-Embedded Binary Black Hole Mergers, Emily Mcpike

Dissertations, Theses, and Capstone Projects

The accretion disks of active galactic nuclei (AGN) are promising environments for producing binary black hole (BBH) mergers, which have been detected via gravitational waves (GW) with LIGO-Virgo-KAGRA (LVK). BBH mergers embedded in AGN disks are unique among GW formation channels in their generic ability to produce electromagnetic (EM) counterparts, via interactions between the merger remnant and the surrounding disk gas (though these are not always observable). While such mergers represent valuable multi-messenger sources, the lack of predictive statistical models in existing literature currently limits our ability to select possible EM counterparts with GW detections in archival data and in …

Variational Methods For Semilinear Pdes With Dirac Singularities, Samuel J. Magill

Dissertations, Theses, and Capstone Projects

This dissertation utilizes a variational framework for semilinear elliptic equations in two dimensions with Dirac measure data. The central objects of study are equations of the form −ΔU = f(U) + Σ_j=1^N α_jδ_pj on bounded Lipschitz domains Ω ⊂ ℝ² with homogeneous Dirichlet boundary condition, and on a flat torus 𝕋², where α_j is positive for the Dirichlet setting and α_j is negative on the torus. Solutions are obtained by minimizing the restriction of an energy functional to an order interval determined by explicit sub- and supersolutions; the Euler–Lagrange equation is recovered …

Essays On Behavioral Aspects Of Retail Operations, Ceren Gultekin

Dissertations, Theses, and Capstone Projects

This dissertation combines a structured literature review on availability signaling in retail with two analytical chapters on inventory disclosure. The literature review incorporates the design and key insights of a systematic review and identifies directions for future research. Inventory disclosure is a form of availability signaling through which retailers strategically communicate stock levels to influence consumer buy-now-or-wait decisions. To mitigate strategic purchase deferrals, retailers may share low stock to create urgency or mask high stock to prevent consumers from relying on abundance. Despite its importance for profitability, academic findings and industry practices vary widely, ranging from consistent sharing to consistent …

Considering Numerical Relativity For Upgrades In Mcfacts Merger Dynamics, Shawn K. Ray

Dissertations, Theses, and Capstone Projects

Binary black hole mergers (BBH), some likely originating from active galactic nuclei (AGN), are observed by ground-based detectors such as LIGO-Virgo-KAGRA (LVK) and will be detected by future space-based detectors such as the Laser Interferometer Space Antenna (LISA) and the Laser Interferometer Lunar Antenna (LILA). The dynamics of AGN may be responsible for a significant fraction of BBH mergers soon to be observed by LISA and LILA, yet the dynamics of BBH mergers within AGN disks remains ambiguous despite their appearance in gravitational wave observations. Monte carlo For AGN Channel Testing and Simulation (McFACTS) is an open-source software used to …
