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. …

Design/methodology/approach: A mixed-methods design combining input- and output-oriented DEA models under constant and variable returns to scale with documentary analysis. Quantitative analysis used secondary data from Etimad platform reports, Ministry of Finance publications, and audited government financial statements (2019–2024), while qualitative analysis examined the Government Tenders and Procurement Law (1440 AH) and related regulations

Findings: DEA results reveal significant variation in …

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 …

“Ite Missa Est”: How Can The Altar Alter Attitudes And Actions?, Ebenezer Akesseh

Journal of Global Catholicism

This paper brings into focus the relationship between personal agency and so-

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

Journal of Contemporary Archival Studies

For the last three years, generative artificial intelligence and its uses have been a frequent topic of conversation. In education, many of us have wondered about the impact that generative AI will have on teaching and student learning. The present study considers the benefits and challenges of using generative AI tools in archival education to improve students’ primary source literacy skills. The focus of the research project is an assignment that uses ChatGPT to remove one of the challenges of developing primary source skills: historical writing. In doing so, the students were able to focus on practicing key archival research …

Fuji Fire: Sifting Ashes Of A Forgotten U.S. Marine Corps Tragedy, Ken Allard

Joint Force Quarterly

Colonel Ken Allard, USA (Ret.), reviews Chas Henry’s Fuji Fire: Sifting Ashes of a Forgotten U.S. Marine Corps Tragedy, an account of the October 1979 fire at Camp Fuji, Japan, that killed 13 Marines and injured more than 73. 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

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 …

On Double Integral Formulas: An English Translation Of E391, Thomas W. Polaski

Euleriana

In this paper, Euler investigates the theory of double intergrals to uses them to find areas, volumes and surface areas. He considers transformations of variables in double integrals. After showing that simple multiplication of the transformed differentials is not appropriate, he derives the formula for a change of variables in double integrals. Euler then uses such changes of variables to investigate areas and volumes, and then turns his attention to the so-called ``Florentine problem.'' This problem requires one to remove four equal windows from a hemispherical surface so that the remaining area is equal to the area of a square. …

It's Your Voice: Why Not Use It?, Tyler Tran

Undercurrents: A Journal of Undergraduate Student Composition

Tyler is an Accounting and Finance major from Stoughton, MA. Tyler felt a personal connection to the topic of his essay as he “has always been conscious of my voice in previous writing assignments, but it wasn’t until English 101 and 102 that I purposefully used my own voice in my essays.” This made Tyler want to explore the topic of “self-censorship” of students when writing. He admits that “undergoing the writing process in a remote setting was very new, but I think it helped emphasize the importance of really writing with my own voice.” While writing this essay, Tyler …

Texts In Conflict, Adia Samba-Quee

Undercurrents: A Journal of Undergraduate Student Composition

Adia is a Political Science Major with a Minor in Africana Studies from Springfield, MA. In writing this essay, Adia was able to “reflect on my relation with writing and how I am perceived as an individual through my writing. I consider letting go of my prideful and embarrassing ego a huge factor in my development.” Like many students, Adia felt the remote learning semesters to be “historically bad on my mental health.” Efforts and interest in school fluctuated wildly and “I didn’t think I’d made much of an impact on my professors this year.” But, Adia is “learning a …

The Repurposing Of Biased Literature For Moral Development, Hannah Ortiz

Undercurrents: A Journal of Undergraduate Student Composition

Hannah Ortiz is an English major with a Professional & New Media Writing concentration, and is from Hartford, Connecticut. Because she is studying reading and writing, Hannah feels that the censorship of literature is an important topic. Hannah says “I love reading and I believe that people, especially children, should be able to read books that teach us about the world.” She states that we do not have to agree with every book we read, but that “literature can present different perspectives that can educate us about messages we don’t agree with.” Hannah believes that biased literature has been some …

Becoming Bilingual: An Experience That Changed My Life, John Nobile Carvalho

Undercurrents: A Journal of Undergraduate Student Composition

John Nobile Carvalho is a Biochemistry major from Uberlandia, Minas Gerais, Brazil. John’s inspiration for writing this paper was in finding the most significant and impactful moments of language learning. The reason he considers his essay important is “because during the writing process I was able to recall memories and think of the journey I’ve been on, and all the challenges I’ve faced while learning two languages.” He also credits remote learning with providing plenty of time to devote himself to his studies and this project: “I was aware that this factor could help me focus and write something interesting …

Improving Security Policy Validation In Distributed Systems Using Attack Graph Simulations, Zaid J. Al-Araji, Balqees Talal Hasan, Fahad Ahmed Shaban, Ali Khairi Al-Toohafi, Hussein M. Farhood, Alaa Al-Dabbagh, Omar Nazar Hamdoon

Al-Bahir

Validation of security policies in distributed systems is difficult because rules are heterogeneous, interact in non-obvious ways, and static checks often overlook multi-stage attacker chains. We offer a unified framework to translate real policies, and in parallel give visibility into policy-aware attack graphs (PAAGs), then we evaluate them using deterministic as well as probabilistic simulations, with Monte Carlo (MC) included. The policies are naturally embedded in the construction; firewall semantics deny or remove exploit edges, RBAC limits privilege transitions, and IDS/IPS lower the success likelihood of edges, so the resulting graph reflects both the vulnerability surface and the enforcement posture. …

Molecular Characterization Of Coprinopsis Sp. Based On Its Rdna Analysis And Evaluation Of Its Antibacterial Activity, Maysaa Taqi Al-Khazali, Kawkab Abdullah Alsaadi, Zahraa Raheem Murshidy, Dhuha Ali Hussein, Sura Abd Ali Kadhim Mohammed

Al-Bahir

The present study, conducted in Karbala Governorate, central Iraq, aimed to identify and characterize large wild fungi belonging to the genus Coprinopsis. Field-collected specimens were found to be Coprinopsis sp. with affinity to Coprinopsis cinerea, based initially on detailed morphological and microscopic characteristics and further supported by molecular analysis of the internal transcribed spacer (ITS) region of ribosomal DNA through comparison with related sequences available in the GenBank database. BLAST analysis revealed minor nucleotide variations, and the obtained sequence was deposited in the NCBI GenBank database under accession number PX247457.1. These findings contribute to the limited records of Coprinopsis species …
