To The Moon: Strategic Competition In The Cislunar Region, Shawn M. Willis

Faculty Publications

China’s advancing space capabilities, particularly in the cislunar region, call for increased cislunar space domain awareness on the part of the United States. US military and civilian decisionmakers must take into account the full scope of China’s cislunar plans and capabilities as the military builds space strategies and future force designs. The United States must also increase near-term investments that support more robust cislunar space domain awareness.

Living Your Best Life: The Mindful Pursuit Of Student-Athlete Thriving, Andrew Augustus

Graduate Theses, Dissertations, and Problem Reports (ETD)

Thriving, or the concurrent experience of healthy well-being and high-level performance, may serve as a valuable construct when studying the optimal student-athlete experience and mindfulness-based interventions (MBIs) have been shown to positively impact well-being and performance. The purpose of the present study began to examine the impact of an MBI for improving student-athlete experiences of thriving via a quasi-experimental longitudinal design. NCAA Division II student-athletes (n = 55) from three sports were randomly assigned to either a control or a 7-session MBI. While comprehensive measures of thriving did not yield significant change for those in the MBI relative to …

Title Theft, Stewart E. Sterk

Articles

Real property owners across the country have been targeted by scammers who prepare deeds purporting to convey title to property the scammers do not own. Sometimes, the true owners are entirely unaware of these bogus transfers. In other instances, the scammers use misrepresentation to induce unsophisticated owners to sign documents they do not understand. Property doctrine protects owners against forgery and fraud—the primary vehicles scammers use in their efforts to transfer title. Owners enjoy protection not only against the scammers themselves, but generally against unsuspecting purchasers to whom the scammers transfer purported title. Recovery of title, however, involves costs and …

Unsettling Human Rights Clinical Pedagogy And Practice In Settler Colonial Contexts, Jocelyn Getgen Kestenbaum, Caroline Bishop Laporte

Articles

In settler colonial contexts, law and educational institutions operate as structures of oppression, extraction, erasure, disempowerment, and continuing violence against colonized peoples. Consequently, clinical legal advocacy often can reinforce coloniality--the logic that perpetuates structural violence against individuals and groups resisting colonization and struggling for survival as peoples. Critical legal theory, including Third World Approaches to International Law (“TWAIL”), has long exposed colonial laws and practices that entrench discriminatory, racialized power structures and prevent transformative international human rights advocacy. Understanding and responding to these critiques can assist in decolonizing international human rights clinical law teaching and practice but is insufficient in …

How To Treat A Woman's Cold And Porous Body: Mugwort Fumigation For Fertility In Medieval And Modern Folk Medicine Of Western And Asian Cultures, Minji Lee

Religion Faculty Scholarship and Creative Works

In the history of gynecology and obstetrics, many medical interventions – direct and indirect–have been suggested to aid women’s fertility. Even when women’s sexual and reproductive organs were not visible or easily treatable, premodern medicine tried to provide women with the right diagnoses and treatments. Fertility affects not only whether women can have children but also whether women can survive birth procedures. Today, ultrasounds and hormone tests are vital and standard diagnostic tools in gynecology. But the absence of these medical technologies did not mean that medieval medicine lacked methods to save women in agony, either by urgent direct interventions …

Expandable Intravertebral Implants In Post-Traumatic Vertebral Necrosis - New Classification Suggestion., Diogo Lino Moura, Josué Pereira Gabriel

Trauma and Acute Care Articles

The progressive evolution of post-traumatic vertebral necrosis and consequent loss of structural integrity of the vertebral body along with neurological risk, makes it one of the most feared and unpredictable pathologies in spine traumatology. Several studies have addressed the role of vertebroplasty, kyphoplasty, and corpectomy in its treatment; however, it remains a controversial concept without a defined therapeutic algorithm. The recent emergence of expandable intravertebral implants, which allow, by a percutaneous transpedicular application, the capacity for intrasomatic filling and maintenance of the height of the vertebral body, makes them a viable option, not only in the treatment of acute vertebral …
