Feedback In Digital Game-Based Learning: A Taxonomy And The Design And Empirical Evaluation Of A Feedback System In A Mathematics Serious Game, André Almo

Dissertations

Digital Game-Based Learning (DGBL) is an active, student-centred pedagogical approach in which feedback plays a central role by informing learners’ actions, guiding decision-making and shaping motivation and engagement. Despite its importance, feedback in serious games is often described inconsistently and insufficiently in research, limiting comparability across studies and the accumulation of design knowledge, particularly for children. This thesis addresses these gaps through two complementary contributions: the development of a taxonomy for feedback design in digital serious games and the empirical evaluation of a taxonomy-informed feedback system in a mathematics game for primary school students. First, this work introduces the Taxonomy …

Interactions Between Air Pollution And Weather/Climate From Urban To Global Scales, Meng Gao, Xin Huang, Yucong Miao, Mengmeng Li, Claudio Mazzoleni

Michigan Tech Publications

Air pollution and meteorology are intricately linked. Weather modulates the formation, transport, and removal of pollutants, while aerosols and trace gases modify radiation balance, cloud microphysics, boundary-layer structure, and other factors. These two-way interactions span scales from urban to global and have important consequences. The papers collected in this special issue of Meteorological Applications examine how interactions between weather and pollution at various scales affect visibility, pollutant transport, crop yields, and other outcomes, collectively highlighting the crucial role of the interplay between air pollution and meteorology.

Countering Wahhabism And Promoting Religious Stability In Kazakhstan: Theological Insights From Qawam Ad-Din Al-Itqani, Rizabek Battaluly, Shamshadin Kerim, Nurlan Anarbayev, Ershat Vice-Rector Ongar

Occasional Papers on Religion in Eastern Europe

Following Kazakhstan’s independence, the expansion of religious freedoms created a societal religious vacuum, which, coupled with the low level of religious literacy among youth, facilitated the spread of radical ideologies. Historical evidence indicates that Wahhabism entered the region through broader Salafi movements, doctrinally grounded in the teachings of Ibn Taymiyya, contributing notably to inter-religious tensions among younger generations. Traditional Islamic frameworks in Central Asia – the Hanafi school of jurisprudence and the Maturidi creed – have historically played a central role in maintaining religious stability. The scholarly works of Qawam ad-Din al-Itqani, a prominent intellectual from the Turkistan region, systematically …

Conceptions Of Law, Ideology, And The Rule Of Law, Alani Golanski

Hofstra Law Review

This Article claims that law and the rule of law ought not be seen as coextensive concepts, for if a legal order’s deviations from rule of law ideals count equally as departures from criteria for being a legal system at all, then the rule of law loses motivation as a discrete concept. In turn, the Article emphasizes the need to galvanize critical assessments of the legal system rooted in rule of law moralities. Toward this end, the argument shifts the terrain on which we discuss law’s nature from concepts to conceptions, critiquing certain currently influential conceptions, with special emphasis on …

The Modern Sisyphus Blows Leaves: Attitudes And Impacts Regarding Leaf Litter Removal On A Suburban Campus, A. C. Nony, M. R. Mcclung, M. L. Reid

Journal of the Arkansas Academy of Science

Leaf litter habitat disruption in suburban spaces stems from the prevalence of “lawn culture,” that is, the accepted societal norm that land immediately surrounding humans or meant for human recreational use should be clean, tidy, controlled, and aesthetically pleasing, above other considerations. When leaf litter on residential and recreational lawns is cleared, it removes vital habitat for organisms of several taxa, especially species that rely on litter as a moisture and temperature-controlled substrate for overwintering. We administered an opinion survey to students, staff, and faculty at Hendrix College, a highly residential and suburban campus in Conway, Arkansas, to assess views …

Creation Of The 2-Way Cross Laminated Timber Subroutine For Computing Dynamic Analysis Parameters, Joseph Freitas

Architectural Engineering

This document will describe the inputs, methodology, and outputs for the CLT 2-way subroutine for cases with and without openings recently added to a proprietary structural analysis software. For the sake of simplicity, most of the discussion will be focused on cases without openings from here on out, as the verification process for a novel method for cases with openings is still in progress. The CLT 2-way module calculates multi-point resistance functions for panels without openings by automating the procedure outlined in an industry-standard structural design manual. The subroutine also finds the appropriate dynamic response factors, kinetic load multipliers, mass, …

Resting-State Eeg Spectral Activity In Children And Adolescents With Asd: Potential Correlations With Interoceptive Neocortical Areas, Stephanie J. Morris

Dissertations

Autism spectrum disorder (ASD) is a developmental condition marked by impairments in social interaction, communication, repetitive behaviors, and differences in cognitive and emotional functioning. These challenges can significantly affect daily living, relationships, and long-term independence, often requiring lifelong support. Emerging research suggests that deficits in interoceptive processing—the ability to perceive internal bodily states—may contribute to ASD symptoms and represent a potential target for intervention.

This study aims to compare resting-state EEG (QEEG) activity between children and adolescents with ASD and neurotypical (TD) peers, and to explore the relationship between interoceptive processing and ASD diagnosis. Archival QEEG data from individuals aged …

Scratch-Induced Damage Of Doped Dlc And Mos2 Coatings—Deep Symbolic Analysis, Ming Liu, Zhitong Xu, Noraphat Yuktanan, Tang Gu, Guangan Zhang, Jinyang Jiang, Fuqian Yang, Rui Liang

Chemical and Materials Engineering Faculty Publications

Understanding contact-induced damage is of paramount importance in the analysis of the lifespan and performance of surface coatings. In this work, we investigate the effects of dopants and interlayers on the structural durability of diamond-like carbon coatings (DLCs) and molybdenum disulfide (MoS₂) coatings on stainless steel via microscratch tests. The analysis of X-ray photoelectron spectroscopy (XPS) survey spectra and Raman spectra of the DLCs shows that the ratio of sp²/sp³ (i.e., the intensity ratio of sp² to sp³ obtained via XPS) is proportional to I_D/I_G, where I_D and …

Program Management And Building Partner Capacity: A Tangled Thicket, Phil W. Reynolds

Publications

This chapter explores how the U.S. Department of Defense plans and executes Building Partner Capacity projects in lower-middle and low-income partners. U.S. planners and practitioners rarely understand the effective pre-conditions that influence partner security apparatus and infrastructure. Consequently, security capabilities provided to the partner are rarely sustained and provide questionable security to the affected population. The U.S. Department of Defense uses a three-part approach to building security with partners: training and equipping, building institutional capacity, and monitoring and evaluating. U.S. security planners should manage all three parts concurrently to produce a security capability that the partner uses and sustains and …

A Phenomenological Study Of Teacher And Student Experience Within A Community Of Inquiry: Utilizing Wonder-Infused Pedagogy In An Elementary Outdoor Classroom, Andrew Gilbert, Steph N. Dean

Publications

This interpretive phenomenological study explores how wonder-infused pedagogy, enacted within an elementary outdoor classroom, supported the development of a community of inquiry. We position the community of inquiry as the overarching framework for cultivating social, cognitive, and teaching presence; wonder as the pedagogical driver; and outdoor learning as the authentic context for engaging in science practices. In response to schooling contexts that often privilege testing and individual achievement over collaborative inquiry, we examined an eight-week outdoor wonder project with third- through fifth-grade students. Data sources included group interviews, student journals, teacher reflections, and photographs. Students engaged in weekly wonder journaling …

Time-Dependent Amplification Of Growth Rates In A Plankton-Oxygen Model, Rapha Coutin

Master's Theses

Near-bottom hypoxia occurs when dissolved oxygen levels drop to a level that is harmful to marine biology, creating biological dead zones along the ocean floor. Recent years have seen a dramatic increase in the percentage of coastal, near-bottom, hypoxic water, with the average in 2021 nearly double that of the average from 2009 to 2018 and about twenty-eight times the average from 1950 to 1980. Recent literature has linked this increase in oceanic hypoxia to the increase in upwelling-favorable winds caused by climate change. Upwelling brings low-oxygen, nutrient-rich water up to the surface, leading to plankton blooms and mass consumption …

Creating Inclusive Educational Environments For Students With And Without Disabilities: Examining Dual Credential Pathways In California, Nat Hansuvadha, Andrew Wall, Meghan Cosier, Kaylie Holke, Audri Sandoval Gomez, Marquita Grenot-Scheyer, Linda Blanton

Thompson Policy Institute on Disability Policy Reports

"In this report, we examined system-level alignment in educator preparation policy, with a particular focus on California’s efforts to prepare teachers to support inclusive PK–12 environments. Central to this analysis was the state’s 'Common Trunk' approach to teacher credentialing. Adopted in 2016 by the California Commission on Teacher Credentialing (CTC), the Common Trunk establishes a unified set of teaching performance expectations (TPEs) that apply across multiple subject, single subject, and education specialist credential pathways. This policy reflects a deliberate shift toward a shared professional foundation for all teachers that emphasizes competencies related to supporting diverse learners, fosters inclusive and culturally …

Unpacking Drivers Of Heterotrophic N2 Fixation Across Aquatic Redox Gradients: A Mathematical Model With Bioenergetic And Stoichiometric Constraints, Corday R. Selden, Rebecca A. Everett, Halvor M. Halvorson, Megan Berberich, Luca Schenone, Angela Peace, Renn Schipper, Edwin Cruz-Rivera, James Powell, Keisuke Inomura, Robinson W. Fulweiler, Amy Marcarelli, J. Thad Scott

Michigan Tech Publications

N2 fixation by aquatic organoheterotrophs supplies bioavailable nitrogen to the biosphere and thereby supports ecosystem production; yet the factors which drive this activity are poorly understood. Here, we present a generalized chemostat model to investigate stoichiometric and energetic constraints on free-living heterotrophic diazotrophs across gradients in redox state, resource quantity/quality, and resource stoichiometry. The model couples nutrient uptake and allocation functions to predict elemental fluxes with an energy dissipation model to calculate growth efficiency. After constraining model parameters with relevant culturing (e.g., Azotobacter) and environmental literature, we assessed model sensitivity to these parameters using Latin Hypercube Sampling and the statistical …

Family Nurse Practitioner Workforce Response To The Public Health Opioid Crisis Through Curriculum Revision, Dayle Sharp, Marcy Doyle, Michelle Capozzoli

All Materials

The opioid crisis continues to pose a critical public health challenge in the United States, demanding an adequately trained primary care workforce. In response, a Family Nurse Practitioner (FNP) program revised its curriculum to prepare students to care for individuals with Opioid Use Disorder (OUD) through a multi-pronged educational intervention. Grounded in Social Cognitive Theory, Situated Learning Theory, and Community of Practice Theory, the revised curriculum integrated a 24-hour Medication for Opioid Use Disorder (MOUD) waiver training, clinical shadowing with MOUD providers, and participation in a 10-month Project ECHO telementoring series based on SAMHSA’s Treatment Improvement Protocol (TIP) 63. Results …

Embrace-Ing Cultural Diversity In Educational Service Delivery: A Framework For Building And Sustaining Equitable Learning Environments, Miguelina Zapata, Devon Dee-Mbappe, Brandan Persaud

The Journal of Special Education Apprenticeship

This paper explores the importance of collaboration in educational service delivery by exploring culturally responsive classroom management practices for education professionals. Educators must understand and critically reflect on their own biases that could impact their interactions with students, families, and colleagues. This is essential not for providing inclusive learning opportunities that address the unique needs of each student. This could lead to misunderstandings and misinterpretations of student behaviors, further complicating effective management and service delivery. Ultimately, the paper argues that through the use of the EMBRACE (Evaluate, Mentor, Build, Reflect, Adapt, Collaborate, and Empower) framework smooth collaboration between and amongst …

Video Generation Techniques For Novel View Synthesis With Flow-Matching Transformers, Xiuyuan Qiu

Master's Theses

Novel view synthesis (NVS) aims to generate images of a scene from unseen camera viewpoints. Recent work, such as Stable Virtual Camera, shows that large-scale image diffusion models like Stable Diffusion can be adapted for pose-conditioned view synthesis by incorporating video-generation techniques with camera conditioning. In this thesis, we introduce MVFlow, a new NVS model that extends this approach to a different image generation architecture: a flow-matching diffusion transformer, specifically FLUX.1, which has demonstrated strong performance in image synthesis. We evaluate MVFlow under varying input view counts and pose distance settings. Our results show that this architectural transfer is feasible; …

Simulation Culture And Organizational Readiness In Social Work Education: Examining Faculty Perspectives., Kate Whitney

Doctor of Social Work Capstone Projects

Despite the growing emphasis on simulation-based learning (SBL), faculty perceptions of organizational readiness for this approach in social work education remain understudied. This exploratory mixed-methods study examined faculty readiness across two CSWE-accredited programs using the Simulation Culture Organizational Readiness Scale (SCORS) and qualitative open-ended questions (𝑁=21). Findings revealed modest and uneven readiness across both programs, with full-time faculty reporting significantly lower readiness scores than adjunct and part-time faculty. Qualitative data identified critical needs for foundational dialogue on SBL principles, strategic institutional investment, and targeted faculty development. Participants also expressed concerns regarding the pace of adoption and potential conflicts with the …
