Autonomous Navigation In Cislunar Satellites, Heith Johnson Sep 2026

Autonomous Navigation In Cislunar Satellites, Heith Johnson

Space and Defense

Cislunar space—the region between Earth’s geosynchronous orbit (about 36,000 kilometers from Earth) and the Moon (roughly 384,000 kilometers away)—is becoming a critical frontier for future space exploration and commercialization.1 This zone includes the Moon’s orbit, transfer orbits, and the Earth-Moon Lagrange points. Additionally, as more nations and corporations launch lunar missions and establish long-term infrastructure, cislunar space is increasingly becoming a strategic focus for exploration, logistics, and transportation.


Planetary Defense As The Ethico-Legal Gateway For International Space Security, Evie Kendal Sep 2026

Planetary Defense As The Ethico-Legal Gateway For International Space Security, Evie Kendal

Space and Defense

Following the news in late 2024 that there was a city-killer asteroid on a possible collision course with Earth, many members of the public were shocked to learn there was no reliable global plan for managing such asteroidal and cometary impact hazards. While calculations of Asteroid 2024 YR4’s trajectory were further refined to exclude the previously reported 2-3% chance of collision in 2032, this event highlighted a major security threat: the lack of a globally coordinated, appropriately resourced, and politically supported planetary defense strategy (Gibney, 2025). In so doing, it also provided an opportunity for security experts to consider the …

When Protection Becomes Predation: Militarized Masculinity And Sexual Violence In Northeastern Nigeria, Tosin Osasona Sep 2026

When Protection Becomes Predation: Militarized Masculinity And Sexual Violence In Northeastern Nigeria, Tosin Osasona

Dignity: A Journal of Analysis of Exploitation and Violence

The study investigates the structural and situational drivers of conflict-related sexual violence (CRSV) perpetrated by state security actors in the context of Nigeria’s counterinsurgency campaigns in Borno State. Drawing on militarized masculinity and strain and deprivation theories, and using a qualitative, interpretive research design, the study argues that CRSV is not an isolated or episodic form of deviance by individual soldiers and security personnel but is embedded in routine military–civilian interactions. Advancing an interactionist explanation of CRSV in Nigeria’s Islamist counterinsurgency operations, the study demonstrates that the likelihood of sexual violence increases through the interaction of gendered institutional norms, operational …

Universalism And Exclusion: Immigrants Through The Lens Of French Law And Media, George Mikhael Taliak, Abellia Anggi Wardani

Paradigma: Jurnal Kajian Budaya

This research examines France’s Immigration Law LOI n°2024-42 du 26 janvier 2024 and its representation in three mainstream media outlets across the ideological spectrum: Le Figaro (right), CCFD-Terre Solidaire (left), and France Info (center). Using Critical Discourse Analysis (Fairclough, 1995) and Maurice Halbwachs’s theory of collective memory, the study explores how legal and media discourses construct symbolic and administrative boundaries of national citizenship. Findings reveal that integration is framed not as civic inclusion, but as the internalization of a singular national identity and memory. Media reinforce this framework through divergent but convergent discursive strategies. At the macro level, the law …

Principals’ Experiences With Implementation Practices For School Board Policies In An Urban School District, Andrea J. Richardson

Walden Dissertations and Doctoral Studies

Effective policy implementation is crucial for improving educational outcomes and ensuring equitable learning environments. While existing literature has shown that policy implementation is influenced by factors such as leadership capacity, stakeholder engagement, communication, resource availability, organization context, and accountability, there is little known about how K-12 urban principals narrate, interpret, and make meaning of their experiences to implementing board-mandated policies. This study addressed this gap by exploring how principals in an urban school district in Ohio navigated the complexities of implementing school board policies amid resource limitations, stakeholder resistance, and accountability pressures. The purpose of this qualitative narrative inquiry study …
