Unveiling Racism: A Systematic Review Of Racism Survey Measures In Education, Wendy Castillo, Juan Cruz, Rachel Renbarger, Christen Priddie, Brein Mosely, Sasha Mejia-Bradford Aug 2026

Unveiling Racism: A Systematic Review Of Racism Survey Measures In Education, Wendy Castillo, Juan Cruz, Rachel Renbarger, Christen Priddie, Brein Mosely, Sasha Mejia-Bradford

Department of Psychology Faculty Scholarship and Creative Works

Education policy research aimed at eliminating racism necessitates methodological innovation that fosters both racial equity–centered approaches and robust empirical analysis of the systemic and structural nature of racism. Most quantitative research in educational psychology does not account for racism in its modeling, thereby obscuring the racialized environments in which students learn (DeCuir-Gunby & Schutz, 2014; Strunk & Andrzejewski, 2023). Drawing from Bronfenbrenner’s ecological systems theory and the ethos of QuantCrit, this study evaluates various scales to highlight gaps and challenges in measuring racism within school settings. This review aims to uplift measures for researchers to use in their work and …

Bridge Simulator Study To Determine The Stopping Distance Of A Large Container Vessel, By Using Anchors, Perera Harindra, K. D. A. P. Sedrick, W. A. N. S. Perera, W. B. C. T. Karunasena

Journal of Innovation in Science, Engineering and Technology

In March 2024, the large containership ``Dali'' suffered a blackout and complete loss of propulsion and steering while outbound from the Port of Baltimore, USA. The vessel was proceeding at about 9 knots in the critical approach channel to the Francis Scott Key Bridge and subsequently allided with the bridge support [\citealpbib6]. As ship sizes continue to increase while channels and bridges remain largely unchanged, understanding realistic emergency maneuvering and stopping capabilities in confined waters has become increasingly important [\citealpbib1].
This paper presents a bridge simulator study to evaluate the emergency stopping distance of a large container vessel using anchors …

Waves Of Exhaustion, Currents Of Renewal: An Autoethnography Of Academic Emotional Burnout And Recovery, Rofiza Aboo Bakar Aug 2026

Waves Of Exhaustion, Currents Of Renewal: An Autoethnography Of Academic Emotional Burnout And Recovery, Rofiza Aboo Bakar

The Qualitative Report

This autoethnography explores my experience of academic burnout and emotional recovery as a mid-career female educator in a Malaysian public university. Drawing from reflective journals, memory work, and embodied recollections between 2023 and 2025, I trace a personal journey through three experiential phases: the weight of expectations, burnout and emotional rupture, and embodied recovery through open sea swimming. The narrative is guided by Chang’s (2016) thematic structuring approach and interpreted through Lazarus and Folkman’s (1984) Transactional Model of Stress and Coping. My story reveals how burnout was not the result of overwork, but of institutional erasure. As I navigated the …

Management Of Peri-Implant Soft Tissue Dehiscence Using Laterally Closed Tunneling With A Connective Tissue Graft: A Case Report, Hisham Tarek

Dentistry

ABSTRACT Peri-implant soft tissue dehiscence is an esthetic complication for which coronally advanced flap with connective tissue grafting remains a predictable treatment, whereas evidence for laterally closed tunneling (LCT) around implants is limited. This single-patient case report describes a 4 × 3 mm labial peri-implant soft tissue dehiscence at an immediately placed implant replacing the maxillary left central incisor. LCT combined with a de-epithelialized free gingival graft and limited implantoplasty was performed. At 24 months, complete coverage was maintained; buccal soft tissue thickness increased from 1.0 to 2.7 mm, keratinized tissue width from 1 to 3 mm, Pink Esthetic Score …

Using Clustering Techniques And Mitre Att&Ck Threat Interpretation To Detect Anomalies In Modbus/Tcp For Industrial Control Systems, Shivanjali Khare, Tirthankar Ghosh, Jhansi Sreya Jagarapu, Atharva Haridas Sagare

Journal of Cybersecurity Education, Research and Practice

Recent attacks on America's critical infrastructure have drawn increased attention on securing industrial control systems and operational technology in power plants, utility companies, and other sectors providing public services. Attack detection and mitigation strategies on these systems have shown promising results using machine learning and other statistical baselining techniques, mostly using supervised learning and classification. Unsupervised learning using cluster analysis and other techniques remain mostly unexplored. In this paper, we propose multi-layered feature extraction and hybrid clustering framework to detect fine-grained nested attack patterns in Modbus-over-TCP traffic. Operating under the assumption of known number of distinct network categories, our approach …

Extended Meshfree Approach For Crack Statistical Analysis Of Anisotropic Functionally Graded Brazilian Disc Subjected To Traction Load, Hassanein Khalaf, Haider Mehbes, Ameen Nassar

Engineering and Technology Journal

An extended meshless method that relying upon Galerkin formulation is applied on the crack analysis of orthotropic functionally graded Brazilian disc. Weak form is involved to solve the governing equation in the numerical method. In addition, enrichment terms and sub-triangle techniques are applied to improve the accuracy of relevant results. This paper depicts the influence of variation in the crack stretch and non-homogeneity parameters on the values of stress intensity factors using a developed MATLAB program. In the isotropic case, it is clear that when the length of crack increases, SIF increases. Graduation in has more effect in increasing the …
