Methacrylic acid‐based amphiphilic block‐random copolymer stabilizers for emulsion polymerization

open access: yesThe Canadian Journal of Chemical Engineering, Volume 101, Issue 9, Page 5222-5230, September 2023., 2023
Abstract The emulsion polymerization of styrene was investigated using polystyrene‐b‐[polystyrene‐r‐poly(methacrylic acid)] amphiphilic block‐random copolymers (BRCs) of different compositions as stabilizers. These stabilizers with molar masses <20,000 g/mol, which possess unique dispersion behaviour (i.e., self‐assembly with low aggregation numbers ...

An elevational gradient in floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus in Peru

open access: yesEcology and Evolution, Volume 13, Issue 8, August 2023., 2023
We analyzed floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus along a steep elevational gradient in Peru. Results show floral traits and pollinator assemblage variation along the elevational gradient. We examined our results considering two hypotheses: (1) local adaptation to different bee assemblages ...

Analysis of trait–performance–fitness relationships reveals pollinator‐mediated selection on orchid pollination traits

open access: yesAmerican Journal of Botany, Volume 110, Issue 6, June 2023., 2023
Abstract Premise The role of pollinators in evolutionary floral divergence has spurred substantial effort into measuring pollinator‐mediated phenotypic selection and its variation in space and time. For such estimates, the fitness consequences of pollination processes must be separated from other factors affecting fitness.

Physics‐based model to predict the acoustic detection distance of terrestrial autonomous recording units over the diel cycle and across seasons: Insights from an Alpine and a Neotropical forest

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 2, Page 614-630, February 2023., 2023
Abstract Passive acoustic monitoring of biodiversity is growing fast, as it offers an alternative to traditional aural point count surveys, with the possibility to deploy long‐term acoustic surveys in large and complex natural environments. However, there is still a clear need to evaluate how the frequency‐ and distance‐dependent attenuation of sound ...

open access: yes, 2015
Nowhere is the crisis of the post-modern subject more evident than in its representations of the body. Post-modernity wavers, anxiously, between em-bodiment and dis-embodiment.

Middlebrow Aesthetics: An Explanation and Defense

open access: yesPacific Philosophical Quarterly, EarlyView.
ABSTRACT We offer a philosophical account of the middlebrow as a theoretical category to do explanatory and critical work in aesthetics. On our account, the middlebrow ought to be understood as aspirational popular art. That is, it is art which aspires both to be popular (in a distinctive sense), and at the same time to be something more than popular ...
