Teacher Perceptions Of School Leadership: Trust, Fairness, And Support As Predictors Of Student Achievement, Trever B. Smith

Honors Theses

This quantitative study examined the relationship between staff–leadership working conditions and student achievement outcomes in Kentucky high schools. This research makes use of extant data from the Impact Kentucky Working Conditions Survey for the 2023-2024 school year. The researcher particularly studied the correlation between teacher perceptions of trust, fairness, and support from principals and student achievement in the Kentucky Summative Assessment (KSA). Teacher perceptions of working conditions were generally favorable, though trust and perceptions of school leadership emerged as weaker areas. Correlation analyses indicated only weak, nonsignificant associations between leadership working conditions and student achievement outcomes at the statewide level. …

Forecasting Big Data Daily Silver Price Based On Hybridizing Support Vector Regression And Meta-Heuristic Algorithms, Ibtihal Muneeb Yahya, Zakariya Yahya Algamal

Baghdad Science Journal

Because commodities are prone to large price swings, forecasting their prices can be extremely difficult. Similar to other commodities, the price of silver is determined by a complicated interplay between a number of factors, including time-lag. Precise forecasting of the silver price is essential for the stable and effective functioning of silver markets. The time series that metal prices follow is non-stationary, nonlinear, and contains periods that fluctuate due to possible growth. Accurate forecasting of silver prices is difficult since they are consistently highly nonlinear and non-stationary. Forecasting metal prices, in general, have been predicted by support vector regression (SVR). …

Optimizing Artificial Neural Networks For Smart Grid Stability Analysis Using Tabu Search-Based Hyperparameter Tuning, Salwa Khalid Abdulateef, Armaneesa Naaman Hasoon, Moceheb Lazam Shuwandy

Baghdad Science Journal

Smart grids are supposed to make electricity networks more reliable, yet in practice their behavior can be surprisingly unstable when the load changes too quickly. During this work, we tried to understand that instability and to build a model that predicts when a grid remains stable or begins to drift. We used an Artificial Neural Network and tuned it with a Tabu Search routine that keeps adjusting the number of neurons and the activation functions until the results stop improving. It was not a single run; several training attempts were needed before the model settled. After applying the Tabu optimization, …

The Power Of Public Vision In Adr, Courtney Verbick

Cardozo Journal of Conflict Resolution (CJCR) Blog

Mediation, a form of alternative dispute resolution (“ADR”), resolves disputes outside of court with a neutral third party that facilitates negotiations. Its confidentiality promotes fairness, neutrality, and candor. This is appealing to parties when litigation could result in bad publicity, and is common in labor disputes, especially during union strikes, where open dialogue is essential.

The print edition of the issue has also been released. This post was originally published on the Cardozo Journal of Conflict Resolution website on November 24, 2025

Development And Applications Of A Health Equity Summary Score Using The Medical Expenditure Panel Survey, Ronald R. Sanchez

Dissertations and Theses

Despite sustained national efforts, disparities in healthcare delivery persist among racial and ethnic minorities, low-income individuals, and socially at-risk populations. Monitoring modifiable aspects of care delivery, such as the structures and processes that health systems can directly improve, is a key strategy for addressing these gaps. However, most measures evaluate modifiable aspects of care delivery separately, limiting understanding of how improvements in one domain reinforce the other and how their combined effect influences equitable care.

This dissertation addresses this gap by combining patient experience and clinical quality, two modifiable aspects of care that captures how patients interact with the health …

Housing Market Responses To Constrained Mobility Rights - Evidence From A School Enrollment Reform For Migrant Children, Yilin Hou, Jinghua Qi, Yugang Tang

Center for Policy Research

Mobility matches open housing markets. With constrained mobility and partially open housing markets, market responses reflect the constraints. We study this mechanism by examining disparity in access to public schools across socio-economic groups, focusing on properties near primary schools accessible to migrant students under social integration policies in a Chinese megacity. Using a difference-in-differences approach, we uncover complex spatial and market dynamics: while house prices close to ordinary primary schools remained relatively stable, house prices farther away declined markedly. This differential impact suggests the interaction between a potential "peer effect" and an "amenity effect." The rental rates showed little change …

Managing Newborn Emergencies By Escaping, Angela M. Schooley

Biennial Convention (CONV)

Development of clinical judgment skills requires active learning strategies. Escape rooms are a unique teaching methodology to support students’ clinical skills (Woodworth, 2020). Participation in active learning strategies such as escape rooms helps students transfer knowledge to practice (Stringfellow, 2021). Students participating in escape rooms report enhanced knowledge, improved ability to prioritize, and increased ability to synthesize data to guide actions (Kubin, 2020). A concern with using game based learning is the retention of the knowledge (Reinkemeyer et al, 2022, Tavares, 2022). While escape rooms are rated favorably by students, more rigorous research is called for to explore the benefits …

Constraints On Axionlike Particles From Veritas Observations Of A Flaring Radio Galaxy In The Perseus Cluster, Avery Archer, C. B. Adams, P. Bangale, J. T. Bartkoske, W. Benbow, J. L. Christiansen, A. J. Chromey, A. Duerr

Physics & Astronomy Faculty publications

Axion-like particles (ALPs) are hypothetical particles that emerge in numerous theoretical extensions to the Standard Model. Their coupling to electromagnetic field implies that ALPs would mix with photons in the presence of external magnetic fields. As ALP phenomenology is governed by the mass and strength of its coupling, there is a subset of this parameter space in which this mixing would be expected to leave an imprint on the spectra of TeV γ-ray sources. In 2017, the VERITAS γ-ray observatory recorded the second day of a dramatic flare of the radio galaxy NGC 1275, embedded at the center of the …

Department of Obstetrics and Gynecology Faculty Papers

Bladder prolapse, also known as cystocoele, is the most common form of pelvic organ prolapse (POP), significantly affecting women's physical, sexual, and psychosocial health, particularly in low- and middle-income countries (LMICs). Despite its widespread prevalence and disabling consequences, bladder prolapse remains under-recognised and inadequately addressed in global health strategies. Prevalence estimates vary widely across regions, from 3%-64.6%, influenced by diagnostic methods and cultural reporting biases. Common risk factors include high parity, early childbirth, prolonged labour, poor postpartum care, malnutrition, obesity, and ageing. Clinical diagnosis often relies on simplified grading systems in resource-limited settings. Conservative treatments like pelvic floor muscle training …

Node-Attributed Spatial Graph Partitioning: A Kullback-Leibler Divergence Based Approach, Valentin Nechita

Electronic Theses and Dissertations 2020 - Present

This thesis presents a novel approach to node-attributed spatial graph partitioning (NSGP) that addresses limitations in existing homogeneity measures. We introduce a Kullback-Leibler (KL) divergence-based formulation we name KLD that measures attribute similarity by comparing each node’s distribution to its subgraph centroid, providing a computationally efficient method of measuring homogeneity. Integrated within a multilevel graph partitioning framework and Fiduccia-Mattheyses refinement, our approach achieves approximately 90% runtime reduction compared to the baseline Clustering and Local Refinement (CLR) algorithm while maintaining comparable partition quality. Applied to COVID-19 infection data combined with American Community Survey demographics across U.S. FIPS codes, KLD successfully identifies …

Enhancing Brain Mri Classification With Gray Wolf Optimization And Swin Transformers, Lamyaa Fahem Katran, Ebtesam N. Alshemmary, Waleed A. Al-Jawher

Baghdad Science Journal

With the rapid advancement of computational power, deep learning has become integral to medical imaging. Convolutional Neural Networks (CNNs) are widely applied to brain MRI scans for tumor classification due to their strong localization and recognition capabilities. However, their limited ability to capture long-range dependencies often leads to information loss and reduced performance in complex feature extraction. To overcome this, the Swin Transformer introduces a hierarchical attention mechanism with shifted windows that preserves spatial relationships and enhances the modeling of global contexts. This architecture improves the detection of intricate tissue textures and supports high-resolution reconstruction of MRI images. Furthermore, integrating …

Transformer Network On Global Self-Attention Mechanism For Brain Tumor Segmentation, Ammar Awni Abbas Baghdadi, Mohammed Al-Mukhtar, Ammar S Al-Zubaidi

Baghdad Science Journal

Transformers are a specific category of neural network design. Transformers often depend on extensive pre-training on a large scale and exhibit a notable degree of computational complexity. The disadvantage of using this method is a significant increase in computational complexity, which necessitates a significant commitment of time and computing resources in order to successfully work with these models. Transformer networks possess the desirable benefit of extracting distant characteristics effectively via their self-attention mechanism. In this paper, the Global Self-Attention Transformer module is applied to tackle these issues. The model is based on a segmentation problem called Brain-GS that works as …

Adolescent Girls’ Uptake Of Prep In Sub-Saharan Africa: A Meta-Aggregation Of Mixed Methods Studies, Susanna Aba Abraham, Dorcas Frempomaa Agyare, Benjamin Kofi Anumel, Mustapha Amoadu

Biennial Convention (CONV)

Background: Sub-Saharan Africa (SSA) is home to 25.9 million people living with HIV, with adolescent girls accounting for 63% of new infections [1,2]. These girls face risks compounded by gender-based violence, and limited sexual education [3]. Pre-exposure Prophylaxis (PrEP), estimated to be 99% effective in preventing HIV from intercourse and 77% from injectable drug use, is a promising prevention strategy [4]. Despite its efficacy, PrEP uptake and adherence among adolescent girls in SSA remain low [3]. This meta-aggregative review synthesizes evidence on PrEP uptake, adherence, facilitators, and barriers among adolescent girls, addressing a critical gap in research.
