This article focuses on engagements with elephants in diverse contexts, inquiring why some scholars are indifferent or even actively opposed to discourses that emphasise elephant suffering. In order to address this question, this article will explore three interrelated streams within social science: one that criticises conservation as an elitist, neo-colonial enterprise; one that is preoccupied with the social construction and cultural interpretation of natural phenomenon; and a third sometimes referred to as the new conservation science that focuses on economic valuations of the benefits nature, viewing “nature is a warehouse for human use.” https://doi.org/10.1080/13880292.2016.1204882 LinkedIn: https://www.linkedin.com/in/helenkopnina/

This paper evaluates a design procedure which is able to scale one-dimensional quadratic-residue diffusers, with integrated Helmholtz resonators. These acoustic structures can be tuned to room modes while fitting within a specified volume. An algorithmic solver is used to control geometric parameters in order to achieve a target frequency. The effect of the diffuser on a room is estimated using Pachyderm. Values obtained with simplified models, that make use of analytically derived coefficients, are compared with those obtained by simulating the full geometry. The predictive power of the simplified modeling made it preferable over simulating the full geometry in comparable scenarios. CFD simulations and measurements taken from a 1:1 scale prototype, are used to evaluate the applicability of lumped mass models to predict resonance frequency and absorption of slit Helmholtz resonators. Although the obtained results remain inconclusive, they indicate a higher inertial attached length for semi-infinite slit resonators, than typically found in literature. If these results can be validated, then the procedure should provide reliable designs.
