I, Cock-A-Doodle-Do: Reclaiming Masculinity Through Queer Joy And Humorous Self-Exploration, Nelson J. Garcia

Graduate Studies Theses and Dissertations 2026

I examine the contemporary norms of masculinity. My research wrestles with ultimately unresolvable stereotypes and imagery influencing current masculine behavior. I unearth queer potential through the physicality and behavior of the stereotypical “man’s man”. I infuse my own queer identity into my studio practice with an emphasis on humor and joy to subvert traditional models of male performance. This process drives self-exploration that allows me to personally respond, react, be directed, and redirected by the interactions between queerness and masculinity. Masculine and queer representations across various media, such as film, music, and television, historically and continuously inform restrictive cultural norms. …

Redox-Mediator Enhanced Electrochemiluminescence Under Non-Aqueous Conditions, Steven J. Blom, Fazeleh Mesgari, El M.S. Martin, Egan H. Doeven, David J. Hayne, Timothy U. Connell, Peter J. Barnard, Narges Saeedizadeh, Seyed Mohammad Jafar Jalali, Paul S. Francis

Research outputs 2022 to 2026

The introduction of small-molecule redox mediators into aqueous co-reactant electrochemiluminescence (ECL) systems has emerged as an effective strategy to increase signal intensity. Herein, we investigate the influence of a series of neutral iridium(iii) complexes (Ir(pmi)3, Ir(ppy)3, Ir(ppz)3 and Ir(ppy)2(acac)) as redox mediators for co-reactant ECL in acetonitrile. Using [Ru(bpy)3]²⁺ as a benchmark luminophore and tri-n-propylamine (TPrA) as a co-reactant, the redox mediators elicit similar effects in this solvent to those of their sulfonated [Ir(sppy)3]³⁻ and [Ir(sppz)3]³⁻ analogues under aqueous conditions. The Ir(ppz)3 complex was most effective; at a concentration of 100 µM it produced an 11-fold increase …

Brief For Jonathan H. Adler As Amicus Curiae Supporting Respondents And Affirmance, Jonathan Adler

Briefs

Global climate change presents many complex and intractable legal and policy questions. Assuming this Court has jurisdiction, the legal questions in this case are comparatively simple and straightforward. Nothing in federal law, let alone the Constitution, preempts state-law claims seeking relief from injuries allegedly caused or exacerbated by petitioners’ conduct.

At issue in this case is whether allegedly aggrieved parties, including subnational governments, may seek redress under state law from defendants otherwise subject to state court jurisdiction for harms allegedly caused or contributed to by petitioners’ conduct. In order to succeed, respondents will ultimately need to show that the damages …

On The Chekist Front: Little-Known Pages Of The Life Of Ivan Voronaev (Agent "Nepliuev"), Founder Of Soviet Pentecostalism, Oleksandr Korotaiev

Occasional Papers on Religion in Eastern Europe

The figure of Ivan Voronaev (1885-1937), founder of the Soviet Pentecostal movement, occupies a contested place in the history of Eastern European Protestantism. Confessional narratives portray him as an “apostle of the Slavs” and martyr of faith, while Soviet anti-sectarian literature depicted him as a “bourgeois agent” and conduit of foreign influence. Despite their opposition, both approaches largely ignore the Chekist dimension of Voronaev’s biography–his systematic interaction with the Soviet security services and his role in their operational activities as a covert agent.

This article reconstructs previously marginalized episodes of Voronaev’s life on the basis of operational, investigative, and reporting …
