Triangulation of interview transcripts, teacher journals, and activity logs ensured methodological rigor. Three key themes emerged: 1) Personalized activity recommendations (e.g., blending …

Beyond Icwa: Within Family Court Systems, Mixed Indigenous Families Confront Ongoing Jurisdictional Violence, Nis Wilbur

American Indian Law Journal

Mixed Indigenous families (MIFs) navigating parental custody in the United States can find themselves trapped in a Battleship®-style jurisdictional maze, where tribal, state, and federal authorities collide unpredictably. This legal mess threatens to separate children from their tribal communities, undermines tribal sovereignty, and can force families into years of costly litigation. The problem is rooted in centuries of white supremacist law and policy that systematically dispossess tribes of culture and self-governance: from the Marshall Trilogy to the boarding school era and harmful adoption schemes. Today, legal frameworks like the UCCJEA remain insufficient as they minimize or ignore tribal civil jurisdiction, …

Workers’ Compensation Codes In American Indian* Tribal Nations, Autumn N. Siegel

American Indian Law Journal

This Article examines various Tribal Nations’ experiences in developing their own workers’ compensation systems using a comparative law and legal development approach, including direct interviews with a diverse range of tribal members. Tribal Nations’ self-created workers’ compensation codes predominantly rely on local models and expertise to establish and operate their systems. However, Tribal Nations also infuse their own cultural values into their codes, incorporating tribal perspectives and priorities such as valuing traditional medicine and peace-making alternative dispute resolution, providing more generously to volunteers, and incorporating return-to-work programs into their workers’ compensation systems. Some Tribal Nations also find it necessary to …

Kopp, Jan Kwakkel, Corey Lesk, Justin Mankin, Robert E. Nicholas, Jennie Rice, Samantha Roth, Vivek Srikrishnan, Moira Scheeler, Nancy Tuana, Chris Vernon, Mengqi Zhao, Klaus Keller

Faculty Scholarship

People around the world seek climate risk information to guide their decisions. For instance, projections about future flood risk inform where households choose to live, how lenders manage credit risks, and which communities receive federal funding. Yet data limitations and fundamental validation challenges raise important concerns about the reliability of such projections. The principles of transparency and reusability help address these concerns by enabling scrutiny of assumptions and methods, development of foundational data and tools, and consistent application of evaluation standards. While there is ongoing debate about how much transparency commercial climate risk services should provide, many expect noncommercial actors …

Codazzi Normalized Null Hypersurfaces, Théophile Kemajou Mbiakop, Cyriaque Atindogbe, Ferdinand Ngakeu

Turkish Journal of Mathematics

We introduce a class of null hypersurfaces of Lorentzian manifolds, namely Codazzi normalized null hyper surfaces, whose (screen) shape operator associated with the rigged vector field is a Codazzi tensor. Several examples are given to support our study. Moreover, we investigate conditions implying that the induced Riemannian screen structure on a Codazzi-type normalized null hypersurface of a Lorentzian space is locally a nontrivial warped product.

The Tribal Rules Of Evidence, Nicole Morote

American Indian Law Journal

Rules of evidence shape litigation practice across the country. In this sense, they govern the truth as it enters the court. Legal scholarship has yet to study tribal approaches to evidence— an area with tremendous promise for legal practitioners and evidence rulemakers alike.

This Article is the first to do so. It analyzes an array of tribal evidence codes across the United States. It reveals three frameworks that describe tribes’ approaches to the Federal Rules. In doing so, it offers a modest contribution to the nascent intersection between Tribal law and evidence studies: crucial insight into tribal systems’ unique needs, …

Advancing The Rights Of Nature: Lessons From Sauk-Suiattle V. City Of Seattle, Harry S. Katz

American Indian Law Journal

Advocates for the “rights of nature” seek recognition of legal rights for natural elements such as mountains, rivers, and non-human species as a means of protecting the environment. In the United States, Tribal Nations have been at the forefront of this nascent movement. In a 2022 Washington state case, the Sauk-Suiattle Indian Tribe sued the City of Seattle, alleging that the City’s hydroelectric dams on the Skagit River infringe upon the rights of salmon. Those rights, they claim, include the salmon’s rights to exist, flourish, regenerate, and evolve. The case, known as Sauk-Suiattle Indian Tribe v. City of Seattle, …

Native History Is United States History: How United States History Censorship Leads To Passive Acceptance Of Racial Discrimination And Furthers The Decline Of Tribal Sovereignty, Nickolasa A. Jackson

American Indian Law Journal

Native stories are embedded in the United States Constitution, property law, and the nation’s legal and political framework, but education frequently omits these truths. Such erasure perpetuates misunderstanding, invisibility, and hostility toward Native communities, obscuring the reality that the United States was built through the dispossession, coercion, and suffering of Indigenous Peoples. Whitewashing history has allowed the nation to claim moral virtue and industriousness while denying the foundational role of Indigenous Peoples. The Article emphasizes that Native rights, whether land, water, or other treaty-protected entitlements, as well as inherent rights such as tribal sovereignty, are not charitable or discretionary; they …

A Neutrosophic Homological-Gröbner Framework For Ai-Driven Media Education Evaluation, Mona Gharib, Hafiz Muhammad Athar Farid, José M. Merigó, Muhammad Riaz

Sustainable Machine Intelligence Journal

The integration of artificial intelligence (AI) with media technologies has transformed teaching in Journalism and Communication, introducing new challenges for quality evaluation. Traditional assessment methods fail to capture the uncertainty, inconsistency, and incompleteness inherent in modern educational data. This paper proposes a Neutrosophic Homological–Gröbner Framework, which unifies three perspectives: neutrosophic sets to encode uncertain evidence, homological algebra to analyze structural coherence, and Gröbner bases to systematically simplify interdependent evaluation rules.

Within this framework, diverse evidence is encoded into neutrosophic triplets, daggregate into course-level indicators, and organized into neutrosophic chain complexes, where Betti indices reveal coherence and fragmentation. Educational policies are …

Vigilante Violence, The Rise Of The New Right, And The Persistence Of The Texas Farmworkers, 1975–1980, Brent M. S. Campney, Tim Bowman

History Faculty Publications

This study charts the ineffective vigilante violence perpetrated by growers in the Rio Grande Valley of Texas to suppress farmworker activism from the mid-to-late 1970s and their abrupt shift in tactics with a 1980 strike in Hereford, Texas, toward the adoption of strictly nonviolent and tediously legalistic new methods associated with the neoconservative backlash. It does so in two major sections. In the first, grower violence is chronicled in detail that underscores both its rage and ineffectiveness. The second section shows how the New Right usurped the longstanding usage of physical violence against ethnic Mexicans in Texas, prompting conservatives to …
