Exit, voice, and adaptive livelihood diversification: Reframing coffee abandonment as transformative climate adaptation in East Africa

Climate change adaptation discourse has a habit of casting smallholder farmers as passive recipients of interventions designed to keep them producing for global market demand. This framing obscures both farmer agency and the power relations embedded in sustainability governance....

Re-presenting the body: Eusebia Cosme’s performative revisions of modernist aesthetics in Negrista poetry

This article examines the career and critical reception of the Afro Cuban declamadora (poetry reciter) Eusebia Cosme during the 1930s–1940s, focusing on her stage performances of poesía negrista (negrista poetry), also known as poesía afroantillana (Afro Antillean poetry). This l...

Generalized Nonlinear Bayesian Pulsar Timing with ENTERPRISE

Abstract We use the Bayesian methods in the ENTERPRISE package to examine the fully general parameterization of pulsar timing models in tandem with noise. We investigate four pulsars, PSRs J1600–3053, J2043+1711, J0740+6620, and J1640+2224, through the lens of Bayesian timing. We...

Crystals in rhyolitic melts can nucleate multiple bubbles: an experimentally constrained model

Abstract Heterogeneous nucleation of bubbles on crystals in magma is thought to be an important driver of volcanic eruptions. Decompression experiments were carried out to elucidate the kinetics of H 2 O bubble nucleation on crystals of different sizes. Samples used were mixtures...

Hyperbolic actions of Thompson’s group F and generalizations

We study the poset of hyperbolic structures on Thompson’s group F and its generalizations F n for n ≥ 2 . The global structure of this poset is as simple as one would expect, with the maximal non-elementary elements being two quasi-parabolic actions corresponding to well-known as...

Beyond “elementary”

Abstract This article examines recent policy debates surrounding the “Elementary Proficiency in a Second Language” (EPSL) requirement at a U.S. liberal arts college, focusing on how misconceptions about language learning and assessment shape curricular decision-making. Drawing on...

Size-DependentChemical Speciation in CementitiousQuarry Waste

Abstract Quarry waste, especially adjacent to cementitious rock formations, presents an underutilized mineral resource given that geo-processes generate gradients in composition across vast scales. We inferred, and demonstrate, that mechanical breakdown depends on chemical compos...

Presenceof CriticalMaterials in Select U.S. MunicipalSolid Waste Landfill Leachates

Abstract This study detected and quantified a broad array of critical materials and other elements in U.S. municipal solid waste (MSW) landfill leachates in both the aqueous (i.e., supernatant) and wet solid fractions. A total of 59 elements were measured in 37 landfill leachate...
