Particular attention is given to the perceived relationship between football performance and electoral cycles, the politicization of the yellow jersey, the use …

Between Peaks And Traditions: Indigenous Andean Women Mountaineers, Hybrid Identities, And Decolonial Resistance Through Sport, Ilina Arsova, Lars Dzikus

Journal of Global South Sport Studies

This paper explores the hybrid identities of Indigenous Bolivian women mountaineers, focusing on how they embrace and resist elements of both Indigenous and Western traditions through sports. Challenging dominant Western narratives of mountaineering (Rak, 2021), these women engage in climbing as an act of cultural preservation (Haynes, 2013; Rak, 2021) and gender advocacy (U.N. Women, 2021). Informed by Indigenous feminism (Caravajal, 2019; Green, 2020) and social identity theory (Tajfel & Turner, 1979), the study explores the intersections of gender, culture, and mountain sports in the South American Andes. Through an interpretivist lens, this study uses narrative inquiry (Clandinin & Connelly, …

The Phoenix Trauma Response Model (Ptrm): An Integrative And Innovative Approach To Trauma Recovery And Growth, Latesha S. Holloman, Lauren B. Robins, Tammie Willis, Courtney V. Morris

Journal of Human Services Scholarship and Interprofessional Collaboration

Trauma is increasingly understood as a developmentally consequential experience that shapes identity, regulation, and relational functioning across the lifespan. Although trauma-informed care, resilience theory, posttraumatic growth, and narrative approaches have expanded understanding of recovery, few frameworks articulate a structured developmental progression that integrates prevention, intervention, and intergenerational transformation within a unified model. The Phoenix Trauma Response Model (PTRM) addresses this gap by introducing a cyclical, phase-based framework organized around four interrelated processes: Recognition, Reframing, Reclamation, and Replication of Strength. Central to the model is the construct of conversion potential, defined as the structured capacity to translate distress into purposeful …

International Journal on Consumer Law and Practice

The rapid growth of the collaborative or sharing economy has posed numerous challenges to traditional legal systems, particularly in relation to short-term accommodation. As a decentralized, intermediary platform, Airbnb raises complex legal issues concerning the allocation of civil liability, enforceability of contracts, and mechanisms for consumer protection. In the context of Vietnamese law, where there is a lack of clear regulatory frameworks to govern digital platforms, consumers risk having their rights infringed without effective legal remedies. The article focuses on three core issues: the legal classification of hosts on Airbnb, the enforceability of clickwrap contracts, and the cross-border enforceability of …

Bot-Theology: Inviting, Prosperous, And (In)Authentic Community, Daniel Jesse

University Faculty Publications and Creative Works

The paper analyzes the theology, emotions, and community formation of the bots who post on YouTube and the people who respond to them. The paper finds that the bots’ theology is evangelical, charismatic, and prosperity-oriented. The paper also finds that the people who respond to the bots are sincere, supportive, and expressive, and that they create a virtual community of faith that is joyful, hopeful, and trusting. The paper suggests that virtual gatherings of Christians need more scholarly attention and that more research is needed on the emotional formation and theological implications of these online interactions.

Ifn Signaling Is Associated With Radiotherapy Response In Malignant Peripheral Nerve Sheath Tumors., Iowis Zhu, Julian Chien, Gabriel E Rech, Kanish Mirchia, Sixuan Pan, Kaeli Miller, Joanna Pak, Rosanna Wustrack, Varun Monga, Steve E Braunstein, Mark D Adams, Line Jacques, Melike Pekmezci, S John Liu, Harish N Vasudevan

Faculty Research 2026

Patients with malignant peripheral nerve sheath tumors (MPNSTs) have poor outcomes despite multimodal treatment with surgery, radiation, and systemic therapy. The responses to radiotherapy (RT) are mixed, and the biologic mechanisms underlying this heterogeneity in the radiation response of MPNSTs are not understood. Here, we combined bulk and single-cell transcriptomics, genome-wide CRISPR interference screens, and multiplatform molecular analysis across MPNST cells, mouse allograft models, and patients' samples to understand the mediators of the radiation response. Our data revealed that MPNSTs, but not benign plexiform neurofibromas, induced a type I IFN signature that functionally mediated the radiation response. Moreover, irradiation of …

Korean Words In The Oed: Race, Gender, And The Modern English Speaker, Elaine W. Chun

Faculty Publications

This article examines representations of the Modern English Speaker of Korean (MESK) in the Oxford English Dictionary (OED), as lexicographers listened to and documented the language of this figure over the past century. I show that, until the early twenty-first century, the most salient type of MESK was the Koreanist, a white, masculine expert on and translator of Korean, the language of a racial other. By contrast, more recent Korean entries, influenced by the global spread of hallyu, have invoked the Korea Fan, a figure that potentially unsettles longstanding ideologies of language, race, and gender. I …

Introduction – Carnets Filmiques, Carnets Sonores : Des Essais Intimes Et Collectifs, Robert Bonamy, Aude Fourel, Eve Le Fessant Coussonneau

Regards

Le sens à attribuer à la notion de carnet filmique ou de carnet sonore suscite quelque indécision, en raison du caractère composite et mouvant des cas envisagés. L’enjeu principal ne paraît ainsi pas ici celui d’une définition serrée d’un objet, mais plutôt une attention accordée à des tentatives de réalisation. De surcroît, si la forme-carnet permet à peu près tout, elle n’interdit donc véritablement rien : l’esquisse, le brouillon, l’approximation, voire l’échec et l’interruption.
