Disentangling Electronic Interactions In F Systems: A Comparative Study On Gdiii, Tbiv, Cmiii, And Bkiv, Chad M. Studvick, Ivan A. Popov, Cristian Celis-Barros

University Research

In this work, we demonstrate through computational spectroscopic analysis of four experimentally accessible f7 ions within complexes (GdIII, TbIV, CmIII, and BkIV) the extent to which electron–electron repulsion, spin–orbit coupling, and the identity of the ligand field influence the energy and intermediate coupling of an f7 ion’s low-lying excited states. As expected, the energy of excited states is primarily governed by electron–electron repulsion in the lanthanides (GdIII and TbIV), whereas spin–orbit coupling and ligand field effects play an increasingly important role in the actinides (CmIII and BkIV). Additionally, the stabilization caused by a ligand field is significantly greater for ions …

Extending W-Event Differential Privacy To The Publish-Subscribe Framework, Jacob Jerome Olinger

Dissertations and Theses

Internet of Things (IoT) devices have become ubiquitous, permeating both enterprises and homes, and they increasingly rely on publish-subscribe (pub-sub) frameworks that give subscribers real-time, high-fidelity access to device data. For privacy and confidentiality, however, today's pub-sub systems largely stop at channel-level authentication, encryption, and access-control lists. These protect data in transit and restrict who may receive it, but place no quantitative limit on what a subscriber with legitimate access to messages can infer about its publishers.

We close this gap by extending w-event differential privacy to the pub-sub setting. We generalize it from count queries to any aggregate …

The goal for this study was to bring attention to this discrepancy by investigating how companies can retain female employees and aid in their career advancement. Interviews of a diverse set of women who all carry relations to the hospitality industry, produced three main themes of flexibility, career support, and work-life balance. Some actions that can be taken by companies to help women advance …

Analysis Of Needs For Web-Based Mobile Learning Development Based On Universal Design For Learning For Students With Special Needs, Murni Winarsih, Mayasari Manar, Rohmah Ageng Mursita, Mita Septiani

Jurnal Pendidikan: Teori, Penelitian, dan Pengembangan

Higher education institutions still have substantial challenges when it comes to accommodating students with special needs, especially those who are visually or aurally impaired. Access to learning resources is still an issue, as are the limitations of adaptive learning media and the dominance of more conventional verbal and visual methods of information transmission. Hence, not all pupils are given the same chances throughout the learning process. With its emphasis on providing a variety of representational, interactive, and expressive tools, Universal Design for Learning (UDL) aims to meet the requirements of students with a wide range of learning styles. In order …

Project-Based Conversion Versus Prototype-Based Instruction In Automotive Teacher Education, Ramdhani Ramdhani, Sriyono Sriyono, Wahid Munawar, Raafi Rizki Maulana, Apriyansah Bahrudin

Jurnal Pendidikan: Teori, Penelitian, dan Pengembangan

The transition to electric and hydrogen mobility is reshaping the competencies that automotive vocational teaching requires, yet institutions with limited equipment must choose between authentic learning designs without evidence of what each produces. Indonesian research to date has built substitute learning media and reported feasibility ratings rather than measured learning. This study asks what cognitive and psychomotor gains two contrasting designs produce and how those gains compare. Two pre-experimental studies were conducted in one automotive teacher education programme in Indonesia. Study A used a time-series design across three project cycles of 200 minutes in which 15 undergraduates converted a combustion …

Twenty Years Later: Measuring The Accessibility Of The U.S. State Government Websites, Tanya Goette, Sean Lynch

Communications of the IIMA

Web accessibility remains an important issue as individuals rely on Internet access and web site accessibility for daily functions. It is an unwritten rule that people should access an organization’s website to search for answers before calling to ask a human (or a bot). Over twenty years ago, in 2005, a study (White, Goette, & Young) was conducted to analyze the accessibility of state government web sites. The assumption was made that state governments should be setting an example of following accessibility guidelines. The study found that about a third of the home pages did not meet basic accessibility guidelines. …

Equal Goals, Unequal Standards: The Policy Debate On Goalpost Dimensions In Women’S Football, Tarlan Chahardovali, Johan Rewilak Ph.D.

Faculty Publications

This study critically examines proposals to reduce goalpost sizes in women’s football; a debate often framed as a practical adjustment to accommodate physiological differences between male and female goalkeepers. Using data from men’s and women’s professional English football within two distinct periods (1951–1975 and 2011–2025), we investigate whether differences in goalkeepers’ height, gender and training are associated with variations in goals conceded. Our findings reveal that taller goalkeepers concede fewer goals; however, this relationship is U-shaped and this benefit diminishes beyond a certain point. We also find that improved coaching and investment, proxied by additional training via national team selection, …

Hydrothermal Alteration Mapping Of The Northern Coongan Greenstone Belt Using Remote Sensing Imagery, Meaza Bogale, Elias Woldeyohanis

Journal of Sustainable Mining

Archean greenstone belts are well known for their ore deposits, diverse lithostratigraphy, and well-preserved evidence from the early Earth. The Northern Coongan Greenstone Belt is an Archean greenstone belt that is part of the Eastern Pilbara Craton of Western Australia. The rock units of this area have the potential to be sources of valuable mineral deposits, which could be economically beneficial for extraction. Studies have been conducted in the northern Coongan greenstone belt, mostly using geological field methods and geophysical interpretations, excluding remote sensing methods for mapping mineral indices. Therefore, this study aims at providing surface mineral distribution maps and …

cial structure, demonstrating that what we celebrate on the altar forms within

us the proper dispositions that can help prevent the occurrence of corruption.

The first part examines corruption from a socio-cultural perspective and ex-

plains the incidence and effects of corruption. The second part discusses the

relationship between worship and the formation of actions and attitudes. It

highlights the need to embody the social implications of our celebrations. Using

responses from interviewees, the third part illustrates that the celebration of the

Eucharist shapes the commitments and conduct …

The Lived Liturgical Experience Of Non-Catholic Participants In The Roman Catholic Mass: Tactical Ecumenism In Overlapping Ritual Systems, Sarah Kathleen Johnson

Journal of Global Catholicism

In religiously diverse social contexts, liturgical practices anchored in one reli-

gious tradition often gather diverse communities. In such contexts, it is wise to

assume that people who are not Catholic may be present at any Roman Cath-

olic Mass. This article explores the lived liturgical experience of non-Catholic

Christians who participate routinely in the Roman Catholic Mass through a

mixed-methods study of a religiously diverse treble vocal ensemble that sings

weekly at Mass on a Catholic university campus. It describes how Catholic and

non-Catholic Christian singers interpret practices surrounding the eucharistic

meal in contrasting ways: non-Catholic Christians experience the …

La Santa Muerte And The Characteristic Damage Of Canonization, Ellen Webber

Journal of Global Catholicism

Devotion to La Santa Muerte, a Mexican folk saint who personifies Death, has

been condemned by the Catholic Church for its affiliation with Mexican drug

cartels. This article challenges mainstream interpretations of La Santa Muerte

devotion using the theological framework of characteristic damage, as defined

by Lauren Winner and Paul J. Griffiths. This framework understands liturgy

as celebrated by sinners in a damaged world, and therefore necessarily damaged

itself. As much as liturgy and Christian practice form us for good, they also per-

petuate damage. I argue that the sins present in La Santa Muerte veneration are

an expression of …

Read, Evaluate, Cite: Using Chatgpt To Teach Primary Source Literacy, Victoria Jones

Drawing on interviews, archival records, maps, command chronologies, and other sources, Henry reconstructs the conditions that produced the disaster, including a fuel farm located uphill from troop quarters, hazardous terrain, and the effects of Typhoon Tip. The book also documents the response of Marines, medical personnel, and commanders, who improvised the collection, treatment, and evacuation of severely burned casualties amid …

Disjointed Command And Air Domain Challenges In Alaska: The Case For A Single U.S. Combined/Joint Force Air Component Commander, Jeffrey W. Kempff

Joint Force Quarterly

The current command and control (C2) organizational structure over the air domain in Alaska is fragmented and doctrinally inconsistent, undermining homeland defense and reducing wartime lethality. Disjointed roles between the North American Aerospace Defense Command (NORAD) and the United States Northern Command (USNORTHCOM)—particularly in the Alaska Theater of Operations (AKTO) and Alaska NORAD Region Area of Operations (ANR AO)—create gaps in unity of command and effort, especially within the air component. This article examines Alaska's fractured air domain organization and command relationships, illustrating operational ambiguity, duplicative efforts, and inconsistencies that delay decision-making. It proposes a focused, near-term solution: unify the …

Mission Over Bureaucracy: Special Operations Command’S Warrior-Driven Model For Defense Innovation, Robert D. Seader

Joint Force Quarterly

In an era of accelerating technological change, military organizations must rapidly develop and field new capabilities to maintain battlefield superiority. Traditional defense acquisition processes, optimized for peacetime oversight and risk avoidance, now take four times longer than in the 1950s, threatening to undermine military effectiveness against rapidly modernizing adversaries. This paper examines how the United States Special Operations Command (USSOCOM) has pioneered a fundamentally different acquisition approach that delivers new capabilities in months rather than the decades typical of conventional programs.

Through extensive interviews with senior acquisition leaders, this analysis identifies three core elements of USSOCOM’s success: a mission-centric culture …

Building The Mental Golden Dome: Arming The Joint Force For Defensive Cognitive Warfare, James Davitch

Joint Force Quarterly

Modern conflict increasingly hinges on mental strength, yet current military thinking lacks a clear defense for the mind. This article introduces a vital new concept: protecting military personnel from an adversary's attempts to distort their perceptions, disorient their judgment, and degrade their decision-making. Building on established research into behavioral psychology, the essay integrates this defense into existing military functions, proposing practical steps. It offers a precise explanation of this protective strategy, suggests pre-deployment exercises for joint personnel, and outlines ways to measure effectiveness even under pressure. A detailed, multi-year plan describes how to update joint doctrine, create training programs, and …

Examining The Lavelle Affair 54 Years Later: An Injustice That Needs To Be Rectified Now, Mark Clodfelter

Joint Force Quarterly

Mark Clodfelter reexamines the case of U.S. Air Force Major General John D. Lavelle, who was relieved as commander of Seventh Air Force in 1972 and reduced in retired rank following allegations that he ordered unauthorized airstrikes against North Vietnam and the falsification of mission reports. Drawing on documentary and recorded evidence, including materials that remained classified until 2015, Clodfelter challenges the findings of earlier congressional and official reviews. He argues that Lavelle acted within an ambiguous command environment shaped by evolving North Vietnamese air defenses, unclear rules of engagement, and guidance from senior military and civilian leaders. The article …

From Data To Victory: The Race For Analytic Superiority In Warfare, Robert Grossman, Emily Goldman

Joint Force Quarterly

Artificial intelligence technologies have reached a tipping point after decades of development. They are diffusing widely across defense and national security applications. Twenty-first century warfighters rely on analytic models in all systems, at all echelons, and in all domains. As more powerful models built on ever larger data sets become ubiquitous, militaries are in a new competition to deploy artificial intelligence. Operational art must embrace “analytic superiority.” This is the operational advantage from collecting and ingesting data, building robust models and computing infrastructure, deploying the models into operational systems, and denying adversaries' ability to do the same

This article explains …

This is a paper that was given and refined at the 2026 Tolkien at Kalamazoo, Tolkien and Leeds and Oxonmoot conferences.

How Euler Could Have Done It: Euler And An Integral Of Ramanujan, Alexander Aycock

Euleriana

We present a derivation of a definite integral discovered by Ramanujan (1887–1920) in his 1915 paper "Some Definite Integrals," from formulas and ideas already developed by Euler (1707–1783). Additionally, it is argued why Euler did not discover Ramanujan's integral himself, although he had all tools required for this task at his disposal.

A Note On Euler's Definition Of The Sum Of A Divergent Series, Alexander Aycock

Euleriana

We outline Euler's theory of divergent series and present another approach he could have taken to sum his ``factorial series". Finally, we address the contradictions that arise from his concept of a sum of a divergent series.

Euler's Explorations Of Extremal Ellipses, Jonathan David Evans

Euleriana

In the 1770s, Euler wrote a series of papers (E563, E691 and E692) about finding the ellipse with minimal area or perimeter in the family of all ellipses passing through a fixed set of points. This is a translation of all three papers from the original Latin, together with a commentary which discusses Euler's results and an appendix which addresses a question from E691 which Euler left for others to consider.

Arithmetic Theorems, Demonstrated By A New Method: An English Translation Of E271, Brendon Lasell

Euleriana

After defending in general terms the value of arithmetic demonstrations, where, according to Euler, the force of genius shines more brightly than in any other kind of demonstration, he goes on to let the force of his own genius shine forth in demonstrating the fact that, for any pair of relatively prime numbers a and N, a^ϕ(N) − 1 is always divisible by N, where we anachronistically denote by ϕ(N) the number of numbers less than N that are relatively prime to it. He approaches this theorem by considering the remainders that result when the numbers in an arithmetic …
