Student-College Match And Retention For Students With Disabilities, Robert Cohen May 2026

Student-College Match And Retention For Students With Disabilities, Robert Cohen

Seton Hall University Dissertations and Theses (ETDs)

Abstract

Outcomes of the student-college matching process have been shown to influence important postsecondary outcomes, including persistence, retention, and degree attainment. However, limited research has examined how matching outcomes operate for students with disabilities. This dissertation investigates student-college matching patterns for students with disabilities and compares the results with matching quality for students without disabilities. This study also examines the relationship between matching outcomes (undermatch, equal match, and overmatch) and first-year retention. Particular attention is focused on the nature of these relationships and any differences by disability status. Data is used from the Beginning Postsecondary Students (BPS:12-17), and filtered to …

A Phenomenological Study Of Elementary Educators’ Experiences Identifying And Responding To Student Asocial Evidence Associated With School Violence Risk, Karen Elizabeth Mcdavitt May 2026

A Phenomenological Study Of Elementary Educators’ Experiences Identifying And Responding To Student Asocial Evidence Associated With School Violence Risk, Karen Elizabeth Mcdavitt

Educational Studies Dissertations

The phenomenon of school shootings is a frightening reality for parents, teachers, and students. Schools should be safe spaces for children; instead, classrooms are spaces in which acts of horrific violence in classrooms occur far too often. Perpetrators of school violence almost always leave a destructive path of warning signs. These warning signs are often exhibited through asocial evidence identifiable in their early years. This phenomenological study examined ways that elementary educators have identified and intervened with students exhibiting asocial evidence associated with school violence risk. An online survey collected qualitative and quantitative data from forty-four elementary educators. Eight of …

At the same time, traditional admissions criteria—focused on grades, attendance, and behavior—have historically limited access for English Learners, students with disabilities, low‑income students, and students of color. The purpose of this study was to investigate …


From Anxiety To Resilience: A Case Study Of Female-Identifying Middle School Students At A Math Summer Camp, Elizabeth Teixeira May 2026

From Anxiety To Resilience: A Case Study Of Female-Identifying Middle School Students At A Math Summer Camp, Elizabeth Teixeira

Educational Studies Dissertations

Mathematics anxiety, defined as a fear that hampers engagement in mathematical tasks (Richardson & Suinn, 1972), affects nearly 50% of students (Johnston-Wilder et al., 2014) and has a disproportionate impact on female students (Devine et al., 2018; Stoet et al., 2016). Math anxiety is often treated in the research literature as a relatively stable trait. This perspective may not fully capture how anxiety manifests in specific moments of mathematical engagement or account for the role of environmental conditions that can both precipitate and mitigate anxious responses. In response to these gaps, this study investigates how mathematics anxiety manifests in …


Elementary Residents And Culturally Sustaining Pedagogy In Mathematics, Quayisha F. Clarke May 2026

Elementary Residents And Culturally Sustaining Pedagogy In Mathematics, Quayisha F. Clarke

Educational Studies Dissertations

This qualitative interpretive embedded case study examines how seven preservice elementary mathematics residents in a Northeastern teacher residency program identify and enact culturally sustaining pedagogy (CSP) (Paris and Alim, 2017) in their math instruction, and how their intersectional identities shape these enactments. Drawing on CSP, intersectionality, and discretionary spaces (Ball, 2018), the study explores how residents interpret, reason through, and make moment-to-moment decisions that affirm students’ learning in mathematics.

Data were collected across two semi-structured interviews, three classroom observations, post-observation debriefs, lesson plans, coursework artifacts, and a researcher's reflexive journal. Analysis followed a hybrid inductive–deductive approach, using thematic and axial …

Oxidized Lipids Are Inflammatory Danger Signals. The Hydrolytic Enzyme Carboxylesterase 1 Regulates Their Metabolic Fate, Thereby Shaping Macrophage Phenotype., Oluwabori Adekanye

Theses and Dissertations

Macrophages originate from hematopoietic progenitors they are immune cells, part of innate immunity. They patrol tissues to identify damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs) from microorganisms. Macrophage pattern recognition receptors (PRRs) detect these signals, and respond by secreting lipid mediators, cytokines, and chemokines, thereby initiating the inflammatory response. Carboxylesterases (CES) belong to the α/β-hydrolase fold family of proteins and catalyze the hydrolysis of ester-containing substrates into alcohols and carboxylic acids. CES1 is one of the six CES identified in the human genome. They are localized in the endoplasmic reticulum lumen and cytosol of cells, primarily expressed in …

Holding Museums Accountable: Utilizing Criminal Sanctions To Support Repatriation Of Illegally Acquired Cultural Property, Mary Jane Apostle May 2026

Holding Museums Accountable: Utilizing Criminal Sanctions To Support Repatriation Of Illegally Acquired Cultural Property, Mary Jane Apostle

Washington and Lee Law Review Online

Antiquities trafficking is the third largest form of illegal trade in the world after arms and drugs. In 2020, over 850,000 stolen or looted antiquities were seized worldwide, with the illegal trade growing significantly due to the rise of social media and online platforms. International law, federal agencies, and civil liability have not been successful in curtailing the illegal antiquities trade.

This Note traces New York’s legal evolution from protecting museums that displayed looted artifacts to mandating greater transparency through origin and ownership disclosures. Central to this shift is the creation of the Antiquities Trafficking Unit (ATU) by the Manhattan …


What Is The Skeleton Of Cognition? A Structural Account Of World Reconstruction Through Processing Axes, Griselda Poe May 2026

What Is The Skeleton Of Cognition? A Structural Account Of World Reconstruction Through Processing Axes, Griselda Poe

Publications and Research

This paper describes how the placement of a single processing axis reorganizes human cognition and generates a reconstructed world.

Most existing psychological and social theories begin from emotion, desire, morality, or social behavior. In doing so, they have discussed what forms on top of the cognitive skeleton without first fixing the skeleton itself. When the skeleton is not fixed, entirely different explanations of the same phenomenon can coexist, and it becomes difficult to identify which constitutes a foundational account.

This paper fixes the skeleton first. That skeleton is the processing axis.

The question is: when a single processing axis organizes …

Frye Is So Last Century: It’S Time For Washington To Get With The Times, Darian Mullen May 2026

Frye Is So Last Century: It’S Time For Washington To Get With The Times, Darian Mullen

Seattle Journal of Technology, Environmental, & Innovation Law

This paper argues that Washington State should finally abandon the

Frye test for expert witnesses and adopt the Daubert test used by federal

courts and most states. It begins with a discussion of the background of

expert witnesses in the U.S. court system and its evolution through Frye.

Then, it looks at the increase in drunk driving in Washington State as a

case study for how the public depends on quality science to protect

individuals and punish wrongdoers. Through the case study, it is

apparent that Frye is an unworkable standard that should be superseded

by Daubert.


Classification Of Hif Detection In Nev Profile Using Wavelet Transform And Convolution Neural Network, Abdul Hafiz Kassim, Mohd Abdul Talib Mat Yusoh, Aster Smith Valentinie Wilson Nottelmarc, Ahmad Farid Abidin, Sim Sy Yi, Daw Saleh Sasi Mohammed May 2026

Classification Of Hif Detection In Nev Profile Using Wavelet Transform And Convolution Neural Network, Abdul Hafiz Kassim, Mohd Abdul Talib Mat Yusoh, Aster Smith Valentinie Wilson Nottelmarc, Ahmad Farid Abidin, Sim Sy Yi, Daw Saleh Sasi Mohammed

Turkish Journal of Electrical Engineering and Computer Sciences

High impedance faults (HIFs) present a critical challenge in power systems due to their subtle signal characteristics, which often remain undetected by conventional protection methods. These faults typically do not produce significant phase disturbances, making reliable detection difficult. However, analysis of the neutral-to-earth voltage (NEV) profile under fault conditions provides a promising alternative for fault identification. Existing approaches for detecting and classifying HIFs using NEV signals remain limited and may result in inaccurate maintenance decisions. This paper proposes a fault classification framework for multiple fault types, including HIF, three-phase fault, three-phase fault to ground, double line, double line to ground, …


Complex-Valued Convolutional Neural Network With Time-Frequency Representation For Electrocardiogram-Based Arrhythmia Detection, Kajeeth Kumar Gurusamy, Muthurajkumar Sannasy May 2026

Complex-Valued Convolutional Neural Network With Time-Frequency Representation For Electrocardiogram-Based Arrhythmia Detection, Kajeeth Kumar Gurusamy, Muthurajkumar Sannasy

Turkish Journal of Electrical Engineering and Computer Sciences

This research proposes an end-to-end procedure for arrhythmia detection based on electrocardiogram (ECG) signals using complex-valued convolutional neural network (CVCNN) incorporated with time-frequency representation. The proposed model leverages complex numbers to capture amplitude and phase information that enhances the ability of the model for detecting time-frequency variation in cardiac signals. First, signal preprocessing techniques---including normalization, wavelet denoising, and R-peak detection---are applied. Subsequently, the model extracts complex features from raw ECG data by employing the Hilbert transform to derive the analytic signal and the short-time Fourier transform (STFT) to generate a time–frequency representation. The proposed CVCNN framework effectively learns spatial-temporal features …

The proposed pipeline consists of four sequential stages: feature extraction, ranking, selection, and classification. Features …


Adaptive Backstepping Nonsingular Fast Terminal Sliding Mode Control For Robotic Manipulators Based On Disturbance Observer, Xin Zhang, Xu Wang May 2026

Adaptive Backstepping Nonsingular Fast Terminal Sliding Mode Control For Robotic Manipulators Based On Disturbance Observer, Xin Zhang, Xu Wang

Turkish Journal of Electrical Engineering and Computer Sciences

This paper presents an adaptive backstepping nonsingular fast terminal sliding mode controller integrated with a nonlinear disturbance observer to achieve precise trajectory tracking of robotic manipulators subject to model uncertainties and unknown time-varying disturbances. A dead-zone–based adaptive gain mechanism is introduced to dynamically adjust the control gain according to the deviation of the sliding surface, thereby enhancing robustness and reducing chattering. The proposed reaching law ensures fast, nonsingular, and adaptive convergence, suppressing high-frequency oscillations without compromising stability and the nonlinear disturbance observer enables real-time estimation and compensation of modeling errors, friction, and external disturbances for superior rejection. The semiglobal uniform …
