Diverse Legalities: Towards A Legal Theory For A Postcapitalist Political Economy, Amy J. Cohen, Stephen Healy Oct 2025

Diverse Legalities: Towards A Legal Theory For A Postcapitalist Political Economy, Amy J. Cohen, Stephen Healy

Law and Contemporary Problems

Law and political economy (LPE) scholars have revived a longstanding debate over the relationship among law, capitalism, and postcapitalist possibility. Is law a creature of capitalism, destined to reproduce its dynamics of exploitation and dominance? Or are there moments of indeterminacy in law that function specifically as openings to a postcapitalist elsewhere?

We enter this debate by posing a different question. Following feminist Marxist economic geographers J.K. Gibson-Graham, we ask what questions arise for LPE scholars if we begin instead with the presumption "that postcapitalist worlds are already here but have been cast into shadow by a singular economic framing …


Optimization Via Strategic Law Of Large Numbers, Xiaohong Chen, Zengjing Chen, Wayne Yuan Gao, Xiaodong Yan, Guodong Zhang Oct 2025

Optimization Via Strategic Law Of Large Numbers, Xiaohong Chen, Zengjing Chen, Wayne Yuan Gao, Xiaodong Yan, Guodong Zhang

Cowles Foundation Discussion Papers

This paper proposes a novel framework for the global optimization of a continuous function in a bounded rectangular domain. Specifically, we show that: (1) global optimization is equivalent to optimal strategy formation in a two-armed decision problem with known distributions, based on the Strategic Law of Large Numbers we establish; and (2) a sign-based strategy based on the solution of a parabolic PDE is asymptotically optimal. Motivated by this result, we propose a class of Strategic Monte Carlo Optimization (SMCO) algorithms, which uses a simple strategy that makes coordinate-wise two-armed decisions based on the signs of …

Induction Of Myelopoiesis By Candida Dubliniensis Drives Protective Trained Immunity Against Sepsis In A Card9-Dependent Manner, Shannon Esher Righi, Elizabeth A. Lilly, Amanda J. Harriett, Patrick W. Daly, Maryjane Jones, Chad Steele, Mairi C. Noverr, Paul L. Fidel

School of Dentistry Faculty Publications

Trained immunity is a long-term functional reprogramming of innate cells that allows for the formation of immune memory akin to adaptive responses, but with a more rapid nonspecific response. We recently identified an anti-inflammatory trained immunity response, termed trained tolerogenic immunity (TTI), induced by low virulence Candida dubliniensis, that protects against acute lethal polymicrobial sepsis via myeloid-derived suppressor cells (MDSCs). Trained immunity and MDSCs arise following hematopoietic stem and progenitor cell (HSPC) expansion in the bone marrow. Here, we show that C. dubliniensis induces inoculum-dependent protection and HSPC expansion, whereas depletion of HSPCs following C. dubliniensis immunization abrogates protection. We …

The Mystery Of Choromytilus Chorus: Factors Affecting The Apparent Demise Of A Culturally Important Mollusk Along Western South America, Shelia Pozorski, Thomas Pozorski

Anthropology Faculty Publications

Choromytilus chorus virtually vanished from most Peruvian archaeological sites about 1000 BC. This species’ disappearance is significant because Choromytilus chorus is one of the most recognizable mollusks in the archaeological remains of coastal Peru because of its large size and rich purple color. In this study we investigate the choro mussel, which was a highly valued food source, a raw material for fishhooks and other fishing gear, and a special ritual item in prehistoric times. We look at inconsistencies in reports of its range, habitat, and ecology to explore reasons for the major shift southward of the species' northern limits …

Aguilar-Durán, Josue Ramírez, Mario A. Rodríguez-Pérez, Christopher J. Vitek, Nadia A. Fernández-Santos, José Guillermo Estrada-Franco

School of Integrative Biological & Chemical Sciences Faculty Publications

Background: Aedes (Stegomyia) aegypti and Ae. (Stegomyia) albopictus mosquitoes are major vectors of diseases including dengue, Zika, chikungunya, and yellow fever. The excessive use of chemical insecticides has caused resistance in mosquito populations, along with negative environmental impacts and harm to non-target organisms. In this regard, mosquito control strategies, such as passive mass trapping interventions with autocidal gravid ovitraps (AGO) offer a promising alternative. Here we report the results of a pilot study evaluating a passive mass trapping treatment using AGOs against Ae. aegypti in the city of Harlingen, Texas, USA, during the peak mosquito season.
