Empirical Vulnerability Function Development Based On The Damage Caused By The 2014 Chiang Rai Earthquake, Thailand, Patcharavadee Hong, Masashi Matsuoka
Empirical Vulnerability Function Development Based On The Damage Caused By The 2014 Chiang Rai Earthquake, Thailand, Patcharavadee Hong, Masashi Matsuoka
Institute for Innovation & Entrepreneurship Publications
Seismic hazards in Thailand are frequently overlooked in disaster management planning, leading to insufficient research and significant economic losses during earthquake events. The 2014 Chiang Rai earthquake exposed critical vulnerabilities in Thailand's building practices due to widespread non-compliance with building codes and limited preparedness. This exposure prompted the development of empirical vulnerability functions using loss data from 15,031 damaged residences. The study analyzed government compensation records, which were standardized using replacement cost metrics. Three distinct models were developed through probabilistic and possibilistic modeling approaches. Residual analysis demonstrated the superior performance of the possibilistic approach, with the Possibilistic-based Vulnerability Function achieving …

Determining The Impact Of Administrative Feedback On The Nctei On Alternatively Licensed Teachers' Self-Efficacy, Lauren P. Hayes
Doctor of Education Dissertations
Alternatively licensed teachers are becoming more present in today’s classrooms. Additionally, teacher evaluation processes are often completed for compliance instead of a meaningful practice. Research shows that when teachers receive high-quality, effective administrative feedback, they experience higher self-efficacy levels. The study aimed to determine the impact of administrative feedback given on the North Carolina Teacher Evaluation Instrument on alternatively licensed teachers’ self-efficacy. The study utilized a Teacher Sense of Efficacy Scale that was distributed to alternatively licensed teachers in a medium-sized North Carolina school district. Teachers were asked to participate, and six participants were randomly selected to participate in individual …

Perceptions, Limitations, And Impacts Of An Outdoor Learning Garden On Elementary-Age Students In A Rural North Carolina District, Kimberly M. Smith
Doctor of Education Dissertations
Outdoor learning gardens are environments where science meets the wonder of a child as they cultivate crops within the boundaries of their schoolyard. When students have opportunities to leave the four walls of their classroom and move outdoors, their minds are awakened and they can explore, analyze, and synthesize information. This mixed methods research investigation took place in a rural North Carolina district on an elementary school campus. The study sought to consider the perceptions of teachers and parents of outdoor learning and the limitations that prevent teachers from including experiential learning opportunities for students. The methodology for the research …

A Phenomenological Study On How White Public Middle School Teachers Who Self-Identify As Racial Allies Experience And Navigate Their Implicit Biases, Joyce Faye Patton
Doctor of Education Dissertations
The teaching force in the United States is overwhelmingly White, while the student population is increasingly diverse, reaching a minority majority in 2014. The racial mismatch between a predominantly White teaching force and students of color in public schools presents barriers for those students as they navigate an educational system built on historical injustices and racism. The study examines the lived experiences of White middle school teachers who identify as racial allies in schools having a student population that is greater than 50% students of color. The interviews revealed that participants understood bias on a basic level yet continued to …

Spatial And Temporal Shifts In Bacterial Communities And Nutrient Removal In Two Springfield Wastewater Facilities, Rubina Sherchan
Graduate Theses/Dissertations
Bacterial communities play a central role in the biological nutrient removal and overall performance of wastewater treatment plants (WWTPs). However, very few is known about the spatial and seasonal dynamics of these communities. This study explores the spatial and seasonal variations in bacterial community composition across multiple treatment stages in two municipal WWTPs—Southwest (SWTP) and Northwest (NWTP)—in Springfield, Missouri. Using 16S rRNA gene amplicon sequencing, I analyzed 87 samples collected during summer and winter of 2024 from influent, sludge, aeration basins, clarifiers, and final effluent stages. I retrieved 16.4 million (summer) and 3.2 million (winter) sequences. Proteobacteria dominated both seasons …

Societal adaptation to rising sea levels requires robust projections of the Antarctic Ice Sheet's retreat, particularly due to ocean-driven basal melting of its fringing ice shelves. Recent advances in ocean models that simulate ice-shelf melting offer an opportunity to reduce uncertainties in ice–ocean interactions. Here, we compare several community-contributed, circum-Antarctic ocean simulations to highlight inter-model differences, evaluate agreement with satellite-derived melt rates, and examine underlying physical processes. All but one simulation use a melting formulation depending on both thermal driving (T⋆) and friction velocity (u⋆), which together represent the thermal and ocean current forcings at the …

Large Language Models (LLMs) play an increasingly integrated and pivotal role in generating diverse types of texts, such as social media messages, emails, narratives, and technical reports, among other textual communication forms. As AI-generated messaging filters into human communication, a systematic exploration of their effectiveness for mimicking human-like communication of life events is needed. In this study, we employ a zero-shot structured narrative prompt to generate 24,000 life event messages for birth, death, hiring, and firing events using OpenAI's GPT-4. From this dataset, we manually classify 2880 messages and evaluate their validity in conveying these life events through the form …

We are reporting the development of a high-performance, non-enzymatic electrochemical biosensor for selective lactate detection, integrating laser-induced graphene (LIG), gold nanoparticles (AuNPs), and a molecularly imprinted polymer (MIP) synthesized from poly(3,4-ethylenedioxythiophene) (PEDOT). The LIG electrode offers a highly porous, conductive scaffold, while electrodeposited AuNPs enhance catalytic activity and signal amplification. The PEDOT-based MIP layer, electropolymerized via cyclic voltammetry, imparts molecular specificity by creating lactate-specific binding sites. Cyclic voltammetry confirmed successful molecular imprinting and enhanced interfacial electron transfer. The resulting LIG/AuNPs/MIP biosensor demonstrated a wide linear detection range from 0.1 µM to 2500 µM, with a sensitivity of 22.42 µA/log(µM) and …

Coastal marshes provide essential ecosystem services, yet they are vulnerable to anthropogenic stressors and climate change, particularly sea level rise (SLR). Restoration approaches like marsh terracing have emerged as nature-based strategies to enhance resilience and reduce habitat loss. This study applies the Sea Level Affecting Marshes Model (SLAMM) to assess the potential of marsh terraces to mitigate future losses, while also examining the model’s limitations, including its assumptions and capacity to reflect complex marsh processes. A geospatial approach was used to generate 3D representations of terraces through morphostatic modeling within digital elevation models (DEMs). Under a no-restoration scenario, SLAMM projections …

Modern wireless communication systems face increasingly complex challenges due to rapidly changing channel conditions and the growing diversity of application-specific Quality of Service (QoS) requirements. Traditional link adaptation mechanisms primarily aim to maximize throughput and often lack the flexibility to support emerging applications, such as Extended Reality (XR) and Virtual Reality (VR), which demand simultaneous guarantees for high data rates, ultra low latency, and high reliability. These stringent and multidimensional QoS needs call for more intelligent and adaptive solutions. In this paper, we propose QDRLLA (QoS-aware Deep Reinforcement Learning-based Link Adaptation), a novel framework that employs deep reinforcement learning to …
