Leveraging A Centralized Fleet Assignment Management For An Aviation Resilience, Inof Seno Acton Mr., Sutanto Soehodho, Nahry Yusuf

Smart City

Since deregulation in the aviation industry, competition among airlines has intensified. This competition is shown by the increasing number of routes, service times, aircraft, and airports served. This competition causes not all flight services to meet their targets, resulting in aircraft operating less efficiently. Passenger seats are not filled, and flight delays are becoming more frequent. Obviously, this will negatively impact consumers and the airline's finances. The study focused on assigning the fleet used to serve flights to maintain existing aviation services and improve aircraft operational efficiency. This study aims to maximize profits by optimizing fleet assignments through the Centralized …

Decarbonizing Electrical Substations: An Integrative Review Of Green Technologies And Sustainable Practices Across The Infrastructure Life Cycle, Sulthan Syah Ali, Mohammed Ali Berawi, Mustika Sari

Smart City

Decarbonization of electrical infrastructure s becoming increasingly important in efforts to meet climate change mitigation targets, particularly in reducing emissions from substations. However, conventional substations continue to release significant quantities of GHG emissions throughout their life cycle As an example, a typical 500 kV substation emits around 150,000 tCO2e from construction to decommissioning. In addition, the development of green substation concepts remains limited, particularly in Indonesia where standardized approaches are not yet established. In response to the need for more sustainable power infrastructure, this study aims to identify, classify, and review all types of green technologies, practices, and innovations that …

Relay Selection And User Scheduling In Reconfigurable Intelligent Surface Assisted Millimeter-Wave D2d Communication, Lakshmikanta Sau

Doctoral Theses

Reconfigurable intelligent surface (RIS) assisted millimeter wave (mmWave) device to device (D2D) communication has recently been proposed as a viable solution to support the overwhelming data traffic in fifth-generation (5G) and beyond wireless networks. However, due to the substantial propagation and penetration losses of mmWave, a direct line of sight (LoS) link between a pair of proximity devices is required for effective communication. Static obstacles like trees and buildings can easily obstruct the direct LoS connectivity between a device pair. In such cases, RISs help to establish an indirect LoS link between an obstructed device pair by reflecting the signals …

The Efficacy Of Open Educational Resources On Achievement Outcomes In Higher Education Institutions, Charles Trevor Alder

Theses and Dissertations

Achievement gaps remain a concern in higher education, reflected in differences in academic performance, retention, and persistence. These gaps often affect students from lower socioeconomic backgrounds and underserved populations. Open educational resources (OER) have been suggested to reduce financial barriers and support student success. This study examined whether student-level and institutional-level factors predict academic performance in a business management course using OER. Average quiz scores were collected from students across 12 higher education institutions and analyzed using hierarchical linear modeling. Colleges were included in the analysis to determine whether outcomes differed based on the proportion of minority and Pell-eligible students. …

Retirement At Risk: The Political Economy Of Public Pension Governance, Allen Mendenhall, Dan Sutter

Journal of New Finance

State public pension systems manage over $6 trillion in assets while facing approximately $1.3 trillion in unfunded liabilities, raising fundamental questions about governance effectiveness and fiduciary accountability. This Article examines these challenges through the analytical framework of governance, applying insights from public choice, principal-agent models, and corporate governance to argue that details in implementation significantly impact outcomes.  We offer Ohio’s State Teachers Retirement System (STRS) as a case study. Recent governance reforms in Ohio—including legislative restructuring of the STRS board and enactment of fiduciary standards legislation modeled on the American Legislative Exchange Council’s framework—suggest the potential for earlier governance problems. …

Analyzing Retirement Systems Through A Triad Framework: Lessons For U.S. Reform, Romina Boccia, Ivane Nachkebia

Journal of New Finance

As U.S. Social Security approaches insolvency, this paper analyzes the program’s challenges through a political economy lens and makes two new contributions. First, it introduces a normative triad framework for evaluating retirement systems based on individual autonomy, fiscal sustainability, and poverty alleviation. Second, it applies this framework to five advanced economies—Canada, Germany, New Zealand, Sweden, and the U.S.—to identify institutional features associated with differences in outcomes. Deriving implications for U.S. reform, we propose four recommendations: transition Social Security to a flat-benefit system, slow benefit growth, adopt automatic stabilizers, and expand flexible savings options.

Teacher Retention: Do Job Satisfaction, Support From Administrators, Professional Development Opportunities, Student Behavior, And School Culture Directly Affect Whether A Teacher Decides To Stay At A School Or Leave?, Robert Dawson Parrott

Education Theses and Dissertations

Teacher retention has reached crisis levels nationwide, with nearly 50% of beginning teachers leaving within five years. Teacher attrition increased to 27.3% in 2022–2023 in a large suburban school district in North Texas. This translated to over $1.1 million dollars in teacher salary expenditures alone. This Dissertation in Practice utilized mixed-methods research grounded in Improvement Science and Plan-Do-Study-Act cycles to explore five campus-level contributors to teacher retention that fell under the control of building-level administrators: job satisfaction, administrative support, professional development, campus culture, and student behavior supports. In Phase 1 a teacher intent survey (n = 63) and focus group …

Using United States Medicare Program Claims To Identify Reliable Measures Of Low Value Services Influenced By Primary Care Physician Decisions, Chris Fleming, Dmitriy Poznyak, Rhea E. Powell, Claire Erba, Eunhae Shin, Rui Wang, Claire Burkhart, Arkadipta Ghosh, Eugene C. Rich

Division of Internal Medicine Faculty Papers & Presentations

BACKGROUND: Low-value services (LVS) are those that “… provide little to no benefit to patients….”¹ Among an existing set of 31 LVS are invasive procedures not typically performed by primary care physicians (PCPs), and other LVS that may be commonly provided by specialists. To facilitate research on the role of primary care physicians in low-value care, we sought to identify the reliability of two subsets of LVS measures that are more directly subject to PCPs’ decisions. We refer to these as primary care adjacent (“PCA”) LVS measures.

METHODS: Retrospective observational cohort study to identify which of a 31-item LVS …

Sirt1 And Ifi16 Cooperatively Regulate Hbv Replication Via Epigenetic Modulation And Innate Immune Activation, Zahra Zahid Piracha, Umar Saeed, Neelam Abid, Syed Shahan Gilani, Hafiz Ahmad Bilal Akhtar Chughtai, Areesha Wasti, Muhammad Waseem, Dilber Uzun Ozsahin, Andromeda M. Nauli, Surya M. Nauli

Pharmacy Faculty Articles and Research

Background

Hepatitis B virus (HBV) establishes persistent infection through the formation of a covalently closed circular DNA (cccDNA) minichromosome, which enables immune evasion and sustained viral replication. While SIRT1, IFI16, and STING are known to modulate antiviral pathways, their cooperative role in regulating HBV transcription and host immunity remains poorly defined.

Methods

We investigated the functional interplay between SIRT1, IFI16, and STING using confocal microscopy, chromatin immunoprecipitation (ChIP), gene silencing, and quantitative PCR in HBV-replicating cell models. Interactions with HBV cccDNA and effects on viral transcription and interferon-stimulated gene (ISG) expression were analyzed. Northern blotting and RT-qPCR were used to …

From Athens To Jerusalem: Platonism, Richard Owen, And The Road Not Taken In Biology, Michael A. Flannery

Libraries Professional Work

Tertullian provocatively asked (circa 200 AD), “What indeed has Athens to do with Jerusalem? What concord is there between the Academy and the Church?” The relationship between formal philosophy and religion has been a contentious battleground ever since. It has historically come into sharpest focus in biology generally, and evolutionary theory specifically. Charles Darwin clearly won the day in the short-term. His evolutionary functionalism looked like an inglorious abandonment of time-honored metaphysical realism for positivist empirical reductionism with a concomitant horizontalization of perspective that has secularized and flattened the intellectual landscape. But more recently the rise of evo-devo (evolutionary developmental …

Examining The Influence Of Job Demands And Resources On The Psychological Well-Being Of Arkansas Teachers, Amy C. Erstine

Student Theses and Dissertations

Teachers across the United States are experiencing declining psychological well-being due to increasing job demands and insufficient workplace resources. In Arkansas, this imbalance contributes to burnout, attrition, and persistent teacher shortages, affecting not only educators but also students, schools, and communities. Job resources are positively associated with well-being, whereas job demands are negatively associated with well-being. Understanding the job resources and demands influencing teacher well-being is critical to sustaining a stable and effective teaching workforce. The purpose of this non-experimental and predictive study was to examine the influence of job demands and resources on the psychological well-being of currently licensed …

A Phenomenological Study Of The Factors Influencing Novice Special Education Teachers’ Career Decisions, Angela L. Norris

Urban Teachers’ Perceptions Of The Influence Of Their Alternate Route Certification Programs On Their Retention, Jenifer Phillips

Student Theses and Dissertations

This qualitative case study explored how secondary teachers in one urban public school system described their experiences in alternate-route certification programs and how those experiences shaped their decisions to stay in the classroom. As districts continue relying on alternate-route teachers to address ongoing shortages, it is important to understand how teachers interpret their preparation, coaching, and early classroom experiences through the lens of adult learning, or andragogy, and what supports they believe actually helped them succeed with students, particularly in areas such as phonological awareness, classroom management, and foundational instructional practices. A total of 196 teachers met the study’s criteria …

Assessing The Effectiveness Of Wetland Reserve Easements As Habitat For Birds In The Mississippi Alluvial Valley Of Eastern Arkansas, Colin K. Dobson

Student Theses and Dissertations

Globally, wetland habitats suffered major declines during the 20th century. In the 1990s, the United States government created the Wetland Reserve Program (later consolidated into the Agricultural Conservation Easement Program), to combat the loss of wetlands. Despite success in attracting landowners, minimal monitoring of properties enrolled into the program (easements) has occurred. In this study, we monitored avian communities at easements, compared avian diversity at easements to agriculture and bottomland forests, and quantified microhabitat, site-specific, and surrounding landscape features at easements. We also studied the demographic rates of an indicator species of bottomland forests, the Prothonotary Warbler (Protonotaria citrea) at …

Social Media And Health Information Sharing In Nigeria: Trends In Weight Loss And Cosmetic Procedures, Victoria Ochanya Agbo

Student Theses and Dissertations

This study examines the role of social media in facilitating (mis)information on weight loss and cosmetic surgeries in Nigeria. Utilizing the Elaboration Likelihood Model (ELM), the study examines information shared by influencers, audience engagements with such messages, and the factors influencing audience receptivity of the messages. Using a qualitative design, a thematic analysis was conducted on influencer posts and audience responses to such posts across major social media platforms. The findings show that influencers frequently framed cosmetic surgery and weight loss as aspirational lifestyle choices and downplayed the medical risks using means such as testimonials, visual transformations, and authenticity cues. …

"Using A Sledgehammer To Crack A Nut" A Proposal To Re-Frame The Media Industry's Perspective On Generative Ai, Reace Barnett

Student Theses and Dissertations

Generative Artificial Intelligence (GenAI) continues to be a divisive topic in the media industry and there are concerns about technical challenges that may affect GenAI’s trustworthiness and reliability. As such, fears of degraded public trust in media products and services have arisen, and while we have a tendency to trust machines, it is clear that public attitudes toward automated decision-making are contentious. Previous research on machine cues found that they are associated with increased perceived objectivity and willingness to disclose information. Conversational GenAI may reduce political polarization, yet many people remain worried about risks such as bias, hallucinations, improper attribution, …

The Transitional Liver Clinic: Study Protocol For A Stepped-Wedge Cluster Randomized Trial, Lindsay Yoder, Elliot B. Tapper, Richard S. Kalman, Mary Rinella, Nicole Bendin, Manisha Verma, Francis Pike, Naga Chalasani, Neha Nalumasu, Eric S. Orman

Decent Work In The Platform Economy Convention, 2026: A Preliminary Analysis, Valerio De Stefano

ILO Decent Work in the Platform Economy Convention

This paper provides a preliminary analysis of the Decent Work in the Platform Economy Convention, 2026 (No. 193), the first international labour standard devoted specifically to platform work. It examines the Convention’s scope, substantive protections, and principal interpretive questions, arguing that its significance lies in the cumulative architecture through which platform work is brought within the reach of international labour standards.

Particular attention is given to the Convention’s broad personal scope. Self-employed platform workers are generally included throughout the instrument, while specific provisions permit protections to be adapted to different employment statuses without excluding workers outside an employment relationship. …

Natural Behavior Vs. Subjective Experience In Fish Welfare Assessments, Ronald G. Oldfield

Animal Sentience

Several commentaries on the Oldfield & Bonano (2024) target article proposed that natural behavior should play a larger role in assessing the welfare of fishes in zoos and aquariums. However, the natural-behavior concept of animal welfare has been widely criticized because natural behaviors do not necessarily improve welfare, and unnatural behaviors do not necessarily reduce it. I review the three major concepts of animal welfare — physical health, natural behavior, and affect/feelings — and argue that behavior patterns, whether natural or otherwise, should be evaluated according to their effects on health and subjective experience. Using the affect/feelings concept and the …

Despite increasing attention to teacher diversity, African American males continue to represent a small percentage of the teaching workforce. This disparity raises important questions about how representation influences the educational experiences of African American students. The purpose of this qualitative phenomenological study was to explore the perceptions of African American male teachers and administrators regarding the impact of the underrepresentation of African American male educators on African American students’ classroom experiences. …

Perceptions Of Trauma-Informed Trained Campus Leadership, Shelly Hardin

Student Theses and Dissertations

The Centers for Disease Control and Prevention define adverse childhood experiences (ACEs) as potentially traumatic experiences that occur in a person’s life between birth and age 17. According to the Substance Abuse and Mental Health Services Administration (2024), more than two thirds of children experience at least one traumatic event by the age of 16, and this is likely an underestimate, as this percentage represents only those cases reported. The physical, emotional, and neurological impact of traumatic experiences can be detrimental to a child’s education, often contributing to learning deficits and behavioral issues. School leaders have the responsibility of creating …
