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 …
