The effectiveness of tasks performed by the directorate of aeronautical engineering and squadrons in RSAF directly impacts flight safety, which in turn influences the organization either positively or negatively. Therefore, improving engineers' competencies will improve the overall performance of the organization. The study refined and reconstructed a model, namely a T-shape competency model, to assess the engineers' competencies which revealed some management and competency-related deficiencies and concluded with managerial recommendations.

Development Of A Security-Focused Multi-Channel Communication Protocol And Associated Quality Of Secure Service (Qoss) Metrics, Paul M. Simon

Theses and Dissertations

The threat of eavesdropping, and the challenge of recognizing and correcting for corrupted or suppressed information in communication systems is a consistent challenge. Effectively managing protection mechanisms requires an ability to accurately gauge the likelihood or severity of a threat, and adapt the security features available in a system to mitigate the threat. This research focuses on the design and development of a security-focused communication protocol at the session-layer based on a re-prioritized communication architecture model and associated metrics. From a probabilistic model that considers data leakage and data corruption as surrogates for breaches of confidentiality and integrity, a set …

A Case Study Of The Efficacy Of Model-Based Requests For Information, Kyle J. Arruda

Theses and Dissertations

The Department of Defense (DoD) has encouraged the transition to digital engineering, yet there are limited guides for how to transition and there is limited data to show where an organization like a program office can reap the most benefit from the transition. To identify areas where potential benefits may be realized, this thesis compares two Requests for Information (RFIs), one document-based and one model-based, from generation to response. A survey was developed and administered to 7 members of a single program office to grade the RFI responses. The survey was based on the 43 benefit categories identified in the …

Generative Methods, Meta-Learning, And Meta-Heuristics For Robust Cyber Defense, Marc W. Chalé

Theses and Dissertations

Cyberspace is the digital communications network that supports the internet of battlefield things (IoBT), the model by which defense-centric sensors, computers, actuators and humans are digitally connected. A secure IoBT infrastructure facilitates real time implementation of the observe, orient, decide, act (OODA) loop across distributed subsystems. Successful hacking efforts by cyber criminals and strategic adversaries suggest that cyber systems such as the IoBT are not secure. Three lines of effort demonstrate a path towards a more robust IoBT. First, a baseline data set of enterprise cyber network traffic was collected and modelled with generative methods allowing the generation of realistic, …

A Practical Tool To Enhance Faculty And Student Interactions Surrounding E-Learning Platforms, Kimberly N. Williams, Alexandria K. Gombas, Claudia Cornejo Happel, Tracy C. Parodi, Elizabeth H. Lazzara, Barbara Chaparro

Publications

Learning management systems (LMS) are prevalent in modern day education, but their implementation is often highly diverse based on individual faculty and course needs. This can result in students falling behind in their schoolwork if they do not understand how faculty use the e-learning platform in specific courses, which may be further exacerbated when students are exposed to many different faculty using learning management systems in different ways at a single institution. The current research sought to create a practical tool to reduce the impact of diverse LMS implementation through the generation of a homepage template that could be customized …

Local Norms And Gifted/Talented Identification In Arkansas, Sarah C. Mckenzie, Josh B. Mcgee, Bich Tran, Kathryn Barnes, Charlene A. Reid

Policy Briefs

In this brief, we summarize recent research from OEP examining if using school- or district-level norms from state assessments would increase the racial and programmatic diversity of Arkansas students identified as Gifted and Talented (G/T). Using ten years of administrative data to analyze the outcomes of a local norms approach compared to the current G/T identification strategies, we find no consistent evidence that using a local norms approach for G/T identification would improve racial or programmatic diversity.

Fused Deposition Modeling With Induced Vibrations: A Study On The Mechanical Characteristics Of Printed Parts, Joseph Dei Rossi, Ozgur Keles, Vimal Viswanathan

Faculty Research, Scholarly, and Creative Activity

The recent development of RepRap style 3D printers has made additive manufacturing technology available to the public at a low cost. While these 3D printers are being used for a variety of purposes, one of the main applications is prototyping in design projects. The quality of the 3D-printed parts has been a concern in such cases. Many variables within these printers’ operation can be varied to obtain optimum print quality. This study explores a setup that uses externally induced mechanical vibrations to the nozzle tip as a potential method to improve the quality of 3D-printed parts. Induced vibration is expected …

Use Of Machine Learning For Early Detection Of Knee Osteoarthritis And Quantifying Effectiveness Of Treatment Using Force Platform, Ashish John Prabhakar, Srikanth Prabhu, Aayush Agrawal, Siddhisa Banerjee, Abraham M. Joshua, Yogeesh Dattakumar Kamat, Gopal Nath, Saptarshi Sengupta

Faculty Research, Scholarly, and Creative Activity

Knee osteoarthritis is one of the most prevalent chronic diseases. It leads to pain, stiffness, decreased participation in activities of daily living and problems with balance recognition. Force platforms have been one of the tools used to analyse balance in patients. However, identification in early stages and assessing the severity of osteoarthritis using parameters derived from a force plate are yet unexplored to the best of our knowledge. Combining artificial intelligence with medical knowledge can provide a faster and more accurate diagnosis. The aim of our study is to present a novel algorithm to classify the occurrence and severity of …

Although physical activity and sedentary behavior are moderately heritable, little is known about the mechanisms that influence these traits. Combining data for up to 703,901 individuals from 51 studies in a multi-ancestry meta-analysis of genome-wide association studies yields 99 loci that associate with self-reported moderate-to-vigorous intensity physical activity during leisure time (MVPA), leisure screen time (LST) and/or sedentary behavior at work. Loci associated with LST are enriched for genes whose expression in skeletal muscle is altered by resistance training. A missense variant in ACTN3 makes the alpha-actinin-3 filaments more flexible, resulting in lower maximal force in isolated type IIA muscle …

Alcohol And Cannabis Co-Use And Longitudinal Gray Matter Volumetric Changes In Early And Late Adolescence, Xi Luo, James J Yang, Anne Buu, Elisa M Trucco, Chiang-Shan R Li

Faculty, Staff and Student Publications

Background: Previous studies have characterized the impact of substance use on cerebral structure and function in adolescents. Yet, the great majority of prior studies employed a small sample, presented cross-sectional findings, and omitted potential sex differences.

Methods: Using data based on 724 adolescents (370 females) curated from the NCANDA study, we investigated how gray matter volumes (GMVs) decline longitudinally as a result of alcohol and cannabis use. The impacts of alcohol and cannabis co-use and how these vary across assigned sex at birth and age were examined. Brain imaging data comprised the GMVs of 34 regions of interest and the …

The QT interval is an electrocardiographic measure representing the sum of ventricular depolarization and repolarization, estimated by QRS duration and JT interval, respectively. QT interval abnormalities are associated with potentially fatal ventricular arrhythmia. Using genome-wide multi-ancestry analyses (>250,000 individuals) we identify 177, 156 and 121 independent loci for QT, JT and QRS, respectively, including a male-specific X-chromosome locus. Using gene-based rare-variant methods, we identify associations with Mendelian disease genes. Enrichments are observed in established pathways for QT and JT, and previously unreported genes indicated in insulin-receptor signalling and cardiac energy metabolism. In contrast for QRS, connective tissue components and …

Informed Consent For Placebo-Controlled Trials: Do Ethics And Science Conflict?, Hope A Feldman, James A Feldman, Charles C Miller, Garrett Walsh, Jon E Tyson

Faculty, Staff and Student Publications

The use of a placebo has been considered the best method for controlling bias in a prospective randomized clinical trial and provides the most rigorous test of treatment efficacy for evaluating a medical therapy. Placebos commonly produce clinically important effects particularly in studies where the primary outcomes are subjective. Yet the potential beneficial or harmful effects of placebos are often not addressed in designing a clinical trial, calculating the sample size, seeking consent, or interpreting clinical trial results. In this manuscript, we use an actual study to indicate three approaches that might be considered in seeking informed consent for placebo-controlled …

Pivoting The Biosafety Program In Response To Covid-19: Recommendations Of Key Services And Tasks To Consider For The Next Pandemic, Robert J Emery, Scott J Patlovich, Kristin G King, Janelle Rios

Faculty, Staff and Student Publications

INTRODUCTION: With the onset of the COVID-19 pandemic, a rapid adjustment of work tasks was necessary for many biosafety programs (and other safety programs) to address drastic shifts in workload demands amid pandemic-related shutdowns and subsequent needs for supporting COVID-19-related safe work protocols, diagnostic testing, research, vaccine development, and so forth. From a program management standpoint, evaluating and understanding these tasks were critically important to ensure that appropriate support and resources were in place, especially during such unprecedented times of rapid change and significant impact to normal life and routine.

METHODS: Described here are examples of how the biosafety program …

Assessing Associations Between Insecure Income And Us Workers' Health: An Ipums-Meps Analysis, Robert D Thomas, John W Davis, Paula M Cuccaro, Gretchen L Gemeinhardt

Faculty, Staff and Student Publications

Gig economy compensation policy initiatives, such as California Prop 22, are increasing the number of US workers receiving piece rate pay (PRP) and other forms of insecure income. However, there is limited evidence about how this trend affects people's health. Using data from the 2008-19 IPUMS Medical Expenditure Panel Survey (MEPS), we examined associations between insecure compensation and US adults' self-reported overall health as well as psychological distress. We report significant associations with three types of insecure income - PRP, hourly, and daily pay - on overall health and psychological distress. These effects were robust to adjustment for suspected confounders, …

The Public Right To Education, Matthew P. Shaw

Vanderbilt Law School Faculty Publications

Public education is "the most important function of state and local government" and yet not a "fundamental right or liberty." This Article engages one of constitutional law's most intractable problems by introducing "the public right to education" as a doctrinal pathway to a constitutional right to education process in three steps. First, it identifies that the otherwise right-to-education foreclosing case, San Antonio Independent School District v. Rodriguez, only contemplated education as a fundamental right or liberty interest. Second, by identifying public education as a due process protected property interest, this Article presents a viable pathway for circumventing Rodriguez. Third, mindful …

Antecedents Of High Performance Work Practices In Smes: An Attention-Based View, Javier Martínez-Del-Río, Pingshu Li, James P. Guthrie

Management Faculty Publications

Relative to the large body of work in the broader strategic HRM (SHRM) literature, knowledge about determinants of SMEs’ approaches to HRM remains limited. We argue that heterogeneity in the use of high performance work practices (HPWPs) is influenced by top managers’ exposure and attention to information obtained via environmental scanning. Invoking an attention-based view (ABV), we develop hypotheses suggesting that competition tracking, participation in trade associations, and social network embeddedness will be associated with greater use of HPWPs. We also propose direct and moderating roles for top managers’ perceptions of competitive intensity. We test our hypotheses using a database …

Social Attention In Realistic Work Environments, Theodore Charles Masters-Waage

Dissertations and Theses Collection (Open Access)

Social attention – the process by which individuals select which aspect of the social world to mentally process – is a key antecedent to all organisational behaviour in groups. This central role of attention has long been appreciated by organisational theorists, but our understanding of this core cognitive process has been hampered by a lack of empirical evidence. To create a method through which organisational scholars can study social attention, this dissertation combines cognitive science measures of attention with recent innovations from social and applied psychology using virtual reality to study naturalistic social behaviour (Chapter 1). This method is then …
