A Place For Ancient Philosophy In Axial Age Historiography, John R. Shook

Comparative Philosophy

Long-standing debates over historiographical approaches to the Axial Age have distracted the history of philosophy from its own disciplined inquiry into the breadth and depth of ancient thought beyond the Greeks. The philosopher Karl Jaspers offered a vista for seeing commonalities among ancient innovations and discerning continuities along history to modern times. That dual agenda divided Axial historiography with the question of whether axiality reflects creativities of ancient systems or have modern reflections created images of axiality. A singular chronology for humanity encourages a mode of philosophical history open to providential designs, epochal turns, spiritual evolutions, psychological leaps, or cognitive …

Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi

Comparative Philosophy

This article offers a comparative philosophical analysis of Confucian liang-zhi (innate moral knowledge) and Islamic fitra(primordial nature), focusing on their accounts of innate morality and moral epistemology. Drawing on classical Confucian sources—especially the praxis-oriented interpretation of Wang Yangming—and foundational Islamic texts and commentary, the study demonstrates that both traditions posit an inborn moral faculty grounding ethical universality and responsibility. Wang Yangming’s liang-zhi is conceived as an innate moral principle that, under the imperative of zhi (to actualize or extend), is continually activated through moral practice. In parallel, fitra is understood as a God-given orientation to truth, cultivated and safeguarded through …

A Constructive Engagement Between Oxford Ordinary Language Philosophy And Latin American & Latine Liberatory Philosophy, Alessandro R. Moscaritolo Palacio

Comparative Philosophy

In this paper, I bring into dialogue a movement in Latin American social and political philosophy – which I have named Latin American and Latine Liberatory Philosophy – and a Western, or more precisely global North, philosophical movement sometimes called Ordinary Language Philosophy. By ‘Latin American and Latine Liberatory Philosophy’, I refer to a movement, adumbrated at the dawn of the 19^th century and developed during the 20^th century, whose guiding theme is the political, social, and cultural liberation of Latin America (and global South peoples more generally). By ‘Ordinary Language Philosophy’, on the other hand, I refer …

High-Performance Green Hydrazine-Based Propellant For Small Spacecraft, Robert K. Masse, Andrew R. Haviland, Benjamin A. Glassy, Ronald A. Spores, Joshua L. Rovey

Small Satellite Conference

Whereas the last decade has seen a notable expansion in the number of small spacecraft on orbit, a lack of high-total-impulse chemical propulsion options continues to hamper their complete proliferation into mission arenas requiring dynamic maneuvering. This has been particularly true at the NanoSat/CubeSat scale, where volume limitations are most constraining. Because SmallSats are generally launched as secondary payloads, green ionic liquid propellants such as ASCENT and LMP-103S have been recognized as particularly advantageous in that they introduce minimal logistical impacts to primary payload integration workflow. However, despite the substantial packaging advantages conferred by their high impulse density, these propellants …

Improving Equity In Financial Aid Policy For Students With Disabilities, Ryan S. Wells, S. Kate Farmer, Morgan D. Woroner

Journal of Student Financial Aid

Disabled college students face significant barriers to degree completion, including systemic inequities in financial aid policies. This Issue Article investigates financial aid policies that unfairly limit aid to disabled students, at times forcing them to choose between maximizing their financial aid and the recommended accommodations to which they have a legal right, such as a reduced courseload. We highlight how current policies, including Pell Grant proration, Satisfactory Academic Progress (SAP) requirements, and lifetime funding caps, create financial and administrative burdens that disproportionately affect disabled students. By examining federal and state-level policy responses, we identify both promising practices and persistent gaps …

Game-Changing Technologies For Green Propulsion Operating With 98% Hydrogen Peroxide, Pawel Surmacz, Adrian Parzybut, Michal Ranachowski, Zbigniew Gut, Michal Alaszkiewicz

Small Satellite Conference

The propellant grade hydrogen peroxide is coming back to space industry. While launcher applications would accept lower grades of High Test Peroxide (HTP) for cost reduction, the highest possible concentration matters much more for in-space propulsion. Every 1% in peroxide concentration translates to the propulsive performance (specific impulse) roughly in 1% for monopropellant and 0.5% for bipropellant.

The highest HTP grade provides certain advantages. While being more reactive, it requires less catalyst for its full decomposition, resulting in hardware mass and cost reduction. When used with any kind of bipropellant (either catalyst-augmented or hypergolic, and including hybrid), the highest grade …

Target Selection For The Pandora Smallsat: A Nasa Mission To Disentangle Stellar And Exoplanet Atmosphere Signals, Knicole Colón, Elisa Quintana, Thomas Barclay, Benjamin Hord, Jessie Dotson, Daniel Apai, Benjamin Rackham, Jason Rowe

Small Satellite Conference

The Pandora SmallSat mission was selected for implementation in 2021 as part of NASA’s Astrophysics Pioneers Program. Pandora is designed to monitor stellar variability while studying the atmospheres of transiting exoplanets via transmission spectroscopy. The transmission spectroscopy technique is one of the best methods to identify the makeup of exoplanetary atmospheres now and in the coming decade. However, stellar variations that occur from the presence of, for example, cool star spots, have been shown to contaminate the exoplanet atmosphere spectra obtained with high-precision transmission spectroscopy measurements. This stellar contamination leads to ambiguous interpretations when attempting to distinguish features like potential …

Romanticism In Tolkien’S The Hobbit: Nature And Domestic Life As A Force For Good, James J. Schultz

Journal of Tolkien Research

J.R.R. Tolkien’s works tend to be viewed by both the public and by scholars through the lens of religious moralism, or else in the context of medievalism, such as with Tom Shippey’s arguments in The Road to Middle Earth. While these take much into consideration in their arguments, these and other works tend to ignore the influences of the Romantic literary movement on Tolkien’s work. This movement, lasting from the late 1700s to the early 1800s, held ideals like beauty and nature in the highest regard. This is seen in some of the most famous works of its time, such …

Stp-H12-Vantage: Combining Visual And Event-Based Sensing For Earth Observation, Diego Wildenstein, Michael J. Cannizzaro, Ian Peitzsch, Linus Silbernagel, Joshua Poravanthattil, Peter Drum, Mark Hofmeister, Cole Bowman, Natan Herzog, Evan W. Gretok, Alan D. George

Small Satellite Conference

Conducting Earth-observation tasks from orbit can provide valuable research insights in fields such as meteorology, geology, forestry, cartography, and defense. Developing and building space payloads for Earth observation poses significant challenges, including the high cost of radiation-tolerant systems, the widening gap between current state-of-the-art apps and the capabilities of space-grade processors, and the increase in fidelity of modern sensors. Many Earth-observation missions typically collect data by leveraging visual and/or multispectral imagers. However, when using conventional imaging, there can be significant losses in context due to the frame-based operation of these sensors, as well as both relevant and irrelevant data mixed …

Doing Business On Indian Reservations: Tribal Business Owners' Perspectives On Entrepreneurship, Terry L. Anderson, Thomas Stratmann

The narratives from these discussions highlight the challenges the current regulatory context poses for entrepreneurial activities and their communities. The participants spoke of regulatory unpredictability and inefficiency, resulting in uncertainty faced by business owners and thus not impeding economic prosperity. The discussions also revealed a disconnect between tribal governments and community members, characterized by a lack of transparency and accountability. Judicial independence emerged as another significant concern. These insights from the focus groups suggest a path forward …

Advancing Literacy Instruction: Bridging Evidence-Based And Culturally Responsive Practices To Serve All Learners, Jamie L. Nord

The Interactive Journal of Global Leadership and Learning

As Minnesota's student population becomes increasingly diverse, persistent literacy achievement gaps among students of color, multilingual learners, and students from low-income backgrounds demand urgent attention. While the state's READ Act mandates structured, evidence-based literacy instruction grounded in the Science of Reading, its successful implementation must not overshadow the equally vital need for culturally and linguistically responsive pedagogy. This white paper argues for a comprehensive, dual-framework approach that integrates both evidence-based literacy practices and culturally affirming instructional strategies

Unlocking Reading Success: Addressing The Literacy Crisis In The United States, Jennifer Kaczrowski-Taylor

The Interactive Journal of Global Leadership and Learning

This white paper addresses the literacy crisis in the United States. Currently, in the educational system, millions of children lack access to research-based reading instruction and, as a result, struggle to become proficient readers. Despite decades of academic and reform efforts, national reading achievement has been declining. This literacy crisis can be traced back to outdated or inconsistent instructional practices, socioeconomic background, lack of research-based instructional curricula, as well as inconsistent and ineffective implementation of these approaches. Based on recent research and national data, this white paper advocates for aligning teacher education and professional development with the Science of Reading. …

An Exploratory Study Of Soft Skills Development Expectations In Two-Year Generation Z College Students, Kelli Hallsten Erickson

The Interactive Journal of Global Leadership and Learning

Workplace demands around competent demonstration of soft skills have been steadily increasing; therefore, institutions of higher education have started focusing attention on instilling these skills within their student populations. The latest generational cohort to enter college and the workforce, Generation Z, has only recently begun to be studied for the impact of its members’ attitudes towards work and how those might change employer expectations around soft skills. A research gap exists, however, regarding students in Generation Z attending two-year schools and which soft skills they feel are most valuable to their future careers. This study sought to explore those attitudes …

Teacher Recruitment And Retention As A School Improvement Strategy, Carl Bryan

The Interactive Journal of Global Leadership and Learning

Fewer issues have received more attention by education researchers than understanding the global teacher shortage, especially in public schools. Concurrent with this issue is the concern that the rate of teacher hires is insufficient to meet the needs of an increasingly diverse body of students. This phenomenon gains significance considering policymakers’ calls for restructuring the way schools do business to meet the needs of students and schools in the era of school accountability. It is crucial not to overlook the substantial body of research which suggests how the practices under No Child Left Behind have complicated the retention of teachers …

Implications Of The Pending Wisconsin Supreme Court Ruling On Act 10, Carl J. Bryan

The Interactive Journal of Global Leadership and Learning

This white paper examines the potential implications of the pending Wisconsin Supreme Court ruling on the constitutionality of 2011 Wisconsin Act 10, a landmark labor law that significantly restricted collective bargaining rights for public sector employees, including teachers and university professors. The ruling stands to reshape the landscape of public sector labor relations in Wisconsin, impacting public educators’ bargaining power, labor-management dynamics, and ultimately, the quality of public education. Drawing on scholarly research, this paper outlines the key challenges posed by the potential legal uncertainty and proposes a multi-pronged approach centered on collaborative labor-management frameworks, contingency planning, inclusive policymaking, capacity …

Microgravity Testing Of A Thermal Start Basket For Propellant Repositioning, Hugh Chen, Álvaro Romero-Calvo

Small Satellite Conference

CubeSat cold-gas propulsion increasingly relies on two-phase propellants stored in conformal tanks. However, state-of-the-art propellant management strategies for these systems result in significant portions of the tank being occupied by vapor, reducing the amount of storable propellant. They also require high power input for vapor expulsion, increasing mission complexity and limiting operational lifetime. These challenges highlight the need for a more robust propellant management approach. The VAporization for PrOpellant Repositioning (VAPOR) experiment investigates the feasibility of repositioning an ullage gas bubble of R-236fa using thermally-induced phase change in various propellant management devices (PMD). These devices utilize a heat source to …

Consolidated Simultaneous Ranging And Clock Synchronization With Application To Positioning In Cis-Lunar Space, Junichiro Kawagichi, Shingo Nishimoto

Small Satellite Conference

The AOWR scheme functions as a set of transceivers connecting two entities: the ground station and the spacecraft. The phase difference information obtained from both sides intrinsically contains data related not only to the range but also to the clock difference simultaneously. The AOWR scheme can synchronize the clock onboard the spacecraft regardless of the distance. In cis-lunar space due to poor geometric configurations, until the position is determined, the clock difference cannot be established. It drastically improves and reduces the dilution-of-precision index. The paper will present the outcomes confirmed through demonstration experiments utilizing hybrid devices related to the GNSS …

We begin by describing a motivation for intelligent extensibility, followed by a review of related work in standards and autonomous multi-agent systems. Next, we present the theoretical definition …

Machine Learning For Interference Detection And Mitigation On Space Telecom Software-Defined Radio Signals, Adhémar De Senneville, Dennis Ogbe, Zaid Towfic

Small Satellite Conference

Detecting anomalies and interference is an essential capability of contemporary flight radios and ground support equipment. The advent of software-defined radios (SDRs) has made this task feasible. These radios allow real-time monitoring and potential mitigation of interference by adjusting frequency bands. This feature is useful as spacecraft components degrade and interference from other instruments may disrupt communications. The implementation of automated anomaly detection systems on SDRs can enhance both spacecraft and ground station testing by identifying abnormal waveforms and potential interference in communication channels. First, this work investigates how machine learning compares against classical signal processing approaches for the anomaly …

Improving Attitude Determination Control System In Small Satellites For Enhancing Data Observation And Enabling Quantum Communication, Marco Ruano

Small Satellite Conference

The growing market for small satellites requires agile, efficient and compact attitude and determination control systems (ADCS) to improve mission performance, enable optical satellite communication (quantum) and improve data observation, increasing precision and agility in control. Reaction wheels are the most widely used active attitude control systems; they offer the advantages of high angular momentum and reduced space, despite problems such as saturation and maximum torque limitations that seriously limit the operability of their satellites, including long pointing wait times and the recovery of momentum-generating capacity (desaturation).
