Comparing Digital And Non-Digital Gamification On Their Impacts In The World Language Classroom, Amanda K. Salmonson
Comparing Digital And Non-Digital Gamification On Their Impacts In The World Language Classroom, Amanda K. Salmonson
All Electronic Theses and Dissertations
Few studies have focused on the comparison between digital and non-digital game-based learning, especially in the world language classroom. This thesis is a literature review of 36 peer-reviewed articles to compare the effects of digital versus non-digital game use in regards to motivation, language acquisition, vocabulary retention, teacher implementation, and student social skills and mental health. The findings show that both styles of gamification have positive impacts in all of these categories when compared to traditional teacher-centered instruction, though when compared, each mode has its benefits and weaknesses. Digital games’ promotion of competition can limit student intrinsic motivation as well …
Engaging Exceptional Learners: Applied Learning Frameworks As A Foundation For Autonomy In Secondary Special Education, Lisa Chovan-Spence
Engaging Exceptional Learners: Applied Learning Frameworks As A Foundation For Autonomy In Secondary Special Education, Lisa Chovan-Spence
All Electronic Theses and Dissertations
Students with mild disabilities are transitioning from high school into the world of work inadequately prepared, even after completing the required transition measures laid out in their Individual Education Programs (IEPs). The transition gap could be remedied by increasing experiential learning opportunities within the core curriculum. Foundational educational psychology and cognitive science validate the use of experiential teaching pedagogies. However, less is written about the use of experiential learning methods in special education and their ability to better prepare students with disabilities (SWD) for this transition. The benefits of experiential learning teaching strategies, such as their propensity to build students' …
Data Sanctuaries: Rethinking Technological Progress To Preserve Federalism, Nathan S. Lee
Data Sanctuaries: Rethinking Technological Progress To Preserve Federalism, Nathan S. Lee
Cardozo Journal of Equal Rights & Social Justice
Why are sanctuary states and cities in the present moment largely failing to protect immigrants and other vulnerable people from federal enforcement of an agenda based on mass deportation and fear? While federalism was painted during the Civil Rights Era as a weapon of states to protect policies of discrimination and segregation, federalism was also a powerful tool used by Northern States before the Civil War to resist Southern and federal laws enabling the dehumanizing capture and transport offugitive slaves (or suspected fugitive slaves). What has changed in the passing years to make federalism seem like such a thin concept, …

How Do African American Alumni At Private Predominantly White Institutions Describe And Interpret The Influence Of Culturally Responsive Support Spaces On Their Sense Of Belonging, Academic Persistence, And Long-Term Professional Development With The Institutional Context, Karen Williams-Blackman
All Student Theses and Dissertations
This qualitative case study examined how African American alumni at a private, predominantly White institution (PWI) in the Midwest described and interpreted the influence of culturally responsive support spaces on their sense of belonging, academic persistence, and long-term professional development. Culturally responsive support spaces are defined as environments that affirm identity, provide protection, and foster community, offering relational and cultural validation beyond traditional institutional diversity or compliance-based initiatives. Guided by Critical Race Theory (CRT) and Validation Theory (VT), this research examined how alumni interpreted their interactions with these support spaces and how such experiences influenced their academic trajectories and enduring …
Plutocratic Public Safety, Erin R. Collins
Plutocratic Public Safety, Erin R. Collins
Law Faculty Publications
Recent political events have laid bare the ways that the United States functions like a plutocracy, in which the ultra-wealthy exert influence over core governance functions. The criminal system is not immune from this influence. Big Capital shapes the operation of the criminal system in highly visible ways through its investments in policing technology, electronic monitoring systems, and correctional and detention systems. This Article shows how the economic elite shape the operation of the criminal system in a less obvious way: through philanthropic giving. Big Philanthropy provides another—albeit seemingly benevolent—avenue through which the ultra-wealthy can advance a vision of public …
The Oxymoron At The Heart Of Delaware's Making Elon Happy Legislation, Franklin A. Gevurtz
The Oxymoron At The Heart Of Delaware's Making Elon Happy Legislation, Franklin A. Gevurtz
McGeorge School of Law Scholarly Articles
Fearing that parties controlling corporations might incorporate elsewhere, Delaware has hurriedly enacted controversial legislation (SB-21) to reduce judicial scrutiny of dealings whereby such parties might further enrich themselves at the expense of public stockholders.
This article examines a basic problem with SB-21 that has been ignored in all the Sturm and Drang surrounding its enactment. Simply put, two key parts of the statute’s provisions addressing dealings by parties who control corporations are fundamentally at war with each other. These are the statute’s definition of controlling stockholder which focuses on the voting power to elect the directors and the statute’s provision …

Background/Objectives: Vestibular disorders can have functional consequences for children, including balance and gross motor delays, academic difficulties and behavioral manifestations; however, they are frequently undiagnosed in children. The purposes of this study were to evaluate the feasibility and clinical utility of performing a non-instrumented dynamic visual acuity (DVA) test as a primary screening tool for children and to examine typical performance on this non-instrumented DVA test in a large sample of children ages 2 through 13 years.
Methods: A clinical DVA test was administered to a convenience sample of 208 children aged 2–13 years. Static visual acuity was assessed using …
Numerical Modeling Of Multi-Scale Jet Feedback In Seyfert Galaxies, Julianne Goddard
Numerical Modeling Of Multi-Scale Jet Feedback In Seyfert Galaxies, Julianne Goddard
Theses and Dissertations--Physics and Astronomy
We present a suite of high-resolution cosmological zoom-in simulations investigating the impact of mechanical and thermal feedback from low-luminosity jets launched from supermassive black holes (SMBHs) on Seyfert galaxy evolution from early cosmic times to the present (z ≤ 10). Our models follow the formation of central galaxies within identical dark matter halos of logMhalo/M⊙ ∼ 11.8 at z = 0, seeded with ∼ 10^6M⊙ SMBHs at z ∼ 9.1 and z ∼ 3.7. Feedback from active galactic nuclei (AGN) is implemented in the form of bipolar jets launched along the SMBH spin axis, with jet powers spanning Ljet ∼ …

Neuroattnfusenet Dual Branch Attention Fusion For Brain Tumor Mri Classification, Md Sanowar Hossain Sabuj, Farzana Sultana, Md Hasan Or Rashid, Rahul Mudhiraj Mullela
Student Publications
Brain tumor MRI classification remains challenging because tumor appearance varies across cases, class boundaries can be visually subtle, and public 2D MRI datasets may contain redundancy or source-specific biases that inflate reported performance. This study proposes NeuroAttnFuseNet, a dual-path attention-guided fusion network for four-class MRI image classification into glioma, meningioma, pituitary, and no tumor. The model combines a Swin-T branch for hierarchical local morphological representation with a frozen DINOv2 ViT-B/14 branch that provides a 768-dimensional global descriptor from the [CLS] token. The Swin and DINOv2 features are concatenated and passed through a channel-attention gate and fusion MLP before final softmax …
The Impact Of Remittances On Food Security In Times Of Crisis—Evidence From Covid-19 In Latin America And The Caribbean, Colin Cannonier
The Impact Of Remittances On Food Security In Times Of Crisis—Evidence From Covid-19 In Latin America And The Caribbean, Colin Cannonier
Funded Scholarship
This study examines the association between workers’ remittances and food insecurity in Latin America and the Caribbean using data from a Coronavirus survey covering over 100,000 individuals during the COVID-19 pandemic. Results indicate that receipt of remittances is associated with an 8.8% decrease (2.5% points) in overall food insecurity. Heterogeneous effects are observed among females, individuals in Latin America, and households with children. Remittances from the USA exhibit a stronger influence on reducing food insecurity. The findings underscore the potential importance of remittances in improving food security at both extensive and intensive margins. Policy issues are also discussed.

Correlates Of Recovery Capital Among Women In Jails: Leveraging A Dimensional Recovery Framework, Amanda Fallin-Bennett, Martha Tillson, Jaxin Annett, Hartley Feld, Michele Staton
Nursing Faculty Publications
Background: Recovery capital encompasses internal and external factors that support recovery from substance use disorder, such as employment, social support, and physical and mental health. There is a need for more research on recovery capital among women who are incarcerated, who often face complex barriers to recovery, such as poverty, unemployment, and histories of trauma.
Methods: Women (N ¼ 900) were recruited from Kentucky jails as part of the broader NIDA-funded Kentucky Justice Community Opioid Innovation Network (JCOIN) cooperative project. Measures from baseline interviews (during incarceration) were selected in alignment with the Substance Abuse Mental Health Service Administration (SAMHSA)’s four …

Financial Status, Fatalism, And Self-Care Of Cardiovascular Disease Risk Factors Among Rural Adults Living In Socioeconomically Distressed Areas, Ashmita Thapa, Geunyeong Cha, Dustin Hodges, Jia-Rong Wu, Misook L. Chung, Martha J. Biddle, Jennifer L. Smith, Debra K. Moser
Nursing Faculty Publications
Purpose: Adults with fewer financial resources often have poor self-care. Rural dwellers commonly have fewer financial resources than urban dwellers and are often stereotyped as fatalistic about health. We examined whether fatalism mediates the association of financial status with cardiovascular disease (CVD) self-care in rural adults in economically distressed areas. We hypothesized that those with fewer financial resources would have poorer self-care, and fatalism would mediate this relationship.
Methods: We enrolled 1,122 adults (53 ± 15 years) at risk for CVD. Financial status was reflected by individuals’ perceptions of how well they made “ends meet” with their financial resources, fatalism …
Cybersecurity Risk Shifting, Deborah R. Farringer
Cybersecurity Risk Shifting, Deborah R. Farringer
Law Faculty Scholarship
This article analyzes the growing problem of ransomware attacks in the healthcare sector and evaluates the evolving legal frameworks used to address cybersecurity risks affecting patient data. The authors trace the rapid increase in ransomware incidents, driven in part by the rise of digital health records and cryptocurrency-enabled extortion, and highlight the significant operational and privacy harms resulting from such attacks. The article critically examines existing federal and state legal mechanisms—including statutes such as HIPAA, criminal fraud provisions, and emerging state-level immunity laws—and argues that current approaches are insufficient due to jurisdictional challenges, particularly the transnational nature of cybercrime and …

Fluid Agency In Ai Systems: A Case For Functional Equivalence In Copyright, Patent, And Tort, Anirban Mukherjee, Hannah H. Chang
Fluid Agency In Ai Systems: A Case For Functional Equivalence In Copyright, Patent, And Tort, Anirban Mukherjee, Hannah H. Chang
Research Collection Lee Kong Chian School Of Business
Modern Artificial Intelligence (AI) systems exhibit fluid agency in multi-step workflows: lacking human-like consciousness or culpability, yet they display behavior that is (i) stochastic (probabilistic and path‑dependent), (ii) dynamic (co‑evolving with user interaction), and (iii) adaptive (able to reorient across contexts). These properties generate valuable outputs but collapse attribution, irreducibly entangling human and machine inputs. Doctrines that assume traceable provenance—authorship, inventorship, and liability—fracture under this unmappability, yielding ownership gaps and moral “crumple zones.”This Article argues that only functional equivalence stabilizes doctrine under unmappability: Where provenance is indeterminate, legal frameworks should treat human and AI contributions as equivalent for allocating rights …

Large Owner Expropriation Threat And Stock Option Pay's Effect On Firm Risk-Taking Behaviors In Weak Institutions, Cuili Qian, Lipeng (Gary) Ge, Xuesong Geng, Jiatao Li, Maria Hasenhuttl
Research Collection Lee Kong Chian School Of Business
Research Question/Issue: This study investigates the impact of managerial stock option pay on firm risk- taking behaviors in aweak institutional context, a critical question that has been overlooked by the literature. Specifically, we build on the comparative corporate governance perspective that emphasizes the implications of large shareholders' expropriation threat in weak institutions to develop predictions about their impact on the stock option's incentive alignment effect. We further explore the boundary conditions of such a relationship.Research Findings/Insights: Based on a sample of Chinese listed firms between 2006 and 2016, we find that a high level of large shareholders' expropriation threat weakens …

Brief Therapy Dog Interactions May Increase Self-Efficacy And Lower Perceived Stress And Cortisol In High School Students: A Preliminary Study, Dawn Melzer, Deirdre Yeater, Madison Derubis, Christiana Rose Kohlroser, Barbara J. Pierce
Psychology Faculty Publications
The present study examined changes in high schoolers’ perceived stress, general self-efficacy and cortisol levels after a brief interaction with a certified therapy dog. High school students completed self-report measures of perceived stress and general self-efficacy and provided salivary cortisol samples both before and after a 10-min interaction with a certified therapy dog. Following the interaction, students reported reductions in perceived stress scores, exhibited lower salivary cortisol concentrations and demonstrated increases in self-efficacy scores compared to before the interaction. Although higher self-efficacy scores were observed, general self-efficacy is generally regarded as a stable construct; therefore, these findings may reflect a …

Key-Point-Based Sign Language Translation With Multi-Stream Motion Modeling And Cross-Lingual Transfer, Alex Muchiri Kagozi
Key-Point-Based Sign Language Translation With Multi-Stream Motion Modeling And Cross-Lingual Transfer, Alex Muchiri Kagozi
Dissertations and Theses
Automatic sign language translation remains challenging because models must recover linguistic structure from complex visual motion while relying on limited annotated data. This thesis investigates whether compact skeletal key-points can serve as an effective alternative to RGB video for continuous sign language recognition and translation, motivated by the privacy, computational efficiency, and transferability of skeletal representations. To address this problem, a segmented key-point-based framework is evaluated in continuous sign language recognition (Sign2Gloss), gloss-mediated translation (Sign2Gloss2Text), gloss-free translation (Sign2Text), and transfer learning within a common modeling pipeline. The proposed framework is a motion-aware multi-stream transformer encoder. Rather than processing the signer …
Factors Influencing Tree Vigor And Structural Failure Along Powerline Corridors In Northern California: A Multi-Species Analysis, David Justin Dorval
Factors Influencing Tree Vigor And Structural Failure Along Powerline Corridors In Northern California: A Multi-Species Analysis, David Justin Dorval
Cal Poly Humboldt theses and projects
Tree failures (e.g., stem breakage, uprooting, or branch drop) can pose significant risks to public safety, particularly along powerline corridors for the risk of power outages and wildfire ignitions. In California, tree-related powerline failures have led to severe ecological and human costs in recent years. Despite extensive research on tree failure in urban environments and post-disturbance contexts, comparatively little empirical work has examined where powerlines intersect largely unmanaged stands. This study evaluates tree failure trends across multiple forest types in Northern California by examining how tree-level characteristics influence recent growth and failure occurrence in regionally dominant tree species. Specifically, the …

Baker Cypress (Hesperocyparis Bakeri) In A Changing Fire Landscape: Characterizing Fire Refugia And Guiding Post-Fire Reforestation, Olivia Lorraine Moskowitz
Cal Poly Humboldt theses and projects
Increasing wildfire frequency threatens serotinous, fire-obligate species that depend on sufficient fire-free intervals to develop seed banks for reproduction. These species require fire intense enough to trigger seed release and create favorable substrate and light levels for regeneration, yet consecutive fires that reburn populations before they reach maturity can cause local population contraction or extirpation. Understanding the environmental drivers of natural regeneration and mature tree survival, as well as when and how active reforestation should supplement natural recovery, is critical for managing fire-adapted species under altered fire regimes.
This thesis uses Baker cypress (Hesperocyparis bakeri [Jeps.] Bartel), a rare …

Skeletal Markers: Interpreting Trauma, Healing, And Survival Through Osteological Remains From Medieval Pomerania, Michael Mulliner-Szyndler
Cal Poly Humboldt theses and projects
Traditionally, studies in bioarcheology have cited the presence of individuals with evidence of healed traumatic injuries and certain pathologies as an indication of social care either at the time of the trauma or throughout the individual’s lifetime. Here, I present three case studies of individuals who present with signs of having survived traumatic injuries and related pathologies. These individuals are from a late medieval cemetery in Żelewo, in the historical region of Pomerania in present-day northwestern Poland. The site is associated with the nearby town of Kołbacz, which is home to the oldest Cistercian monastery in Pomerania. This study aims …

Aquatic Habitat Use By Western Toads And American Bullfrogs In California’S Central Valley: Effects Of Local Habitat Characteristics And Landscape Composition, Kaitlyn Breana Hernandez
Cal Poly Humboldt theses and projects
Drastic losses of historic wetland habitat in the California Central Valley have caused widespread population declines and extirpations of aquatic breeding amphibians. Efforts to restore wetland habitat have included private land, which represents 70% of land tenure in the Central Valley. Management of these restored wetlands is focused on waterfowl with the assumption that they will provide habitat for native herpetofauna. This study used combined surveys to test the assumption that restored wetlands on private land provide habitat for native amphibians with the western toad (Anaxyrus boreas) as a case study. The objectives were to use environmental DNA …

The Effects Of Temperature On The Persistence Of Environmental Dna In Self-Preserving Filters, Megan Boche
Cal Poly Humboldt theses and projects
This study investigates the effectiveness of self-preserving filter packs (filters designed to passively dry and stabilize captured eDNA without liquid preservatives or cold-chain) in maintaining the integrity of environmental DNA (eDNA) under varying temperature and environmental conditions. eDNA degradation was assessed at three temperatures (23, 33, and 43 °C) using water collected from two distinct study sites that differ in species composition and salinity, a freshwater hatchery and a brackish lagoon. To capture early degradation dynamics, eDNA concentrations were quantified using quantitative PCR assays immediately after filtration (t = 0) and after 2, 4, 8, 16, 32, and 64 days …
Relational Approaches To Fire Resilience: Designing A Living Shaded Fuel Break With Indigenous Knowledge Systems, Natalee Nicole Lopes
Relational Approaches To Fire Resilience: Designing A Living Shaded Fuel Break With Indigenous Knowledge Systems, Natalee Nicole Lopes
Cal Poly Humboldt theses and projects
Escalating wildfire severity across California reflects not only changing climatic conditions but also the cumulative impacts of colonial land management systems that have disrupted Indigenous fire stewardship and altered forest structure and function. This project examines how wildfire mitigation infrastructure, specifically linear fuel treatments, such as fuel breaks, can be reimagined through Indigenous relational frameworks of care-based land stewardship. Grounded in Happy Camp (Athithúfvuunupma), California, within the ancestral homelands of the Karuk Tribe along the mid-Klamath River, this research is carried out in collaboration with Karuk knowledge holders, centering Indigenous knowledge systems and priorities.
Using a mixed-methods approach that integrates …
