Amidst (waste) abundance: world‐making and struggles in hosting a municipal landfill in the Bolivian lowlands Au milieu de l'abondance (de déchets) : fabrication du monde et luttes liées à la gestion d'une décharge municipale dans les basses terres de Bolivie

Journal of the Royal Anthropological Institute, EarlyView.
In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

On cosmological perturbations of quasidilaton [PDF]

Classical and Quantum Gravity, 2013
A theory of the quasidilaton is an extension of massive gravity by a scalar field, nonlinearly realizing a certain new global symmetry of the Lagrangian. It has been shown that unlike pure massive gravity, this theory does admit homogeneous and isotropic spatially flat solutions.

The birth of an earth being: ‘Rights of nature’ in Brazilian Amazonia and elsewhere Naissance d'un être de la terre : « droits de la nature » en Amazonie brésilienne et ailleurs

Journal of the Royal Anthropological Institute, EarlyView.
In June 2023, the Laje River, located in the traditional territory of the Wari’ Indigenous people in Rondônia, Brazil, was declared a legal entity, an earth being, with rights, following the co‐ordinated action of an indigenous councillor and non‐indigenous activists.

AI as guru or conjurer?

American Ethnologist, EarlyView.
Abstract This commentary examines how artificial intelligence (AI) reshapes scholarly authorship through Fredrik Barth's figures of the guru and the conjurer. The guru instructs within moral and scholarly frameworks, while the conjurer mystifies through spectacle.

Dependence of Inflationary Reconstruction upon Cosmological Parameters

, 1995
The inflationary potential and its derivatives determine the spectrum of scalar and tensor metric perturbations that arise from quantum fluctuations during inflation.

ASYMPTOTICS OF LINEARIZED COSMOLOGICAL PERTURBATIONS [PDF]

Journal of Hyperbolic Differential Equations, 2010
In cosmology an important role is played by homogeneous and isotropic solutions of the Einstein–Euler equations and linearized perturbations of these. This paper proves results on the asymptotic behavior of scalar perturbations both in the approach to the initial singularity of the background model and at late times. The main equation of interest is a

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming

Gender, Work &Organization, EarlyView.
ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...

In situ single‐spot Rb/Sr cosmochronology of roedderite in the Ribbeck aubrite (asteroid 2024 BX1)

Meteoritics &Planetary Science, EarlyView.
Abstract The mineralogy and textures of several fragments from the Ribbeck aubrite were analyzed using a combination of scanning electron microscopy, electron microprobe analysis, μRaman spectroscopy, and laser ablation inductively coupled reaction cell mass spectrometry (LA‐ICP‐MS/MS).

Scalar Cosmological Perturbations

, 2020
In this paper we present the study of the scalar cosmological perturbations of a single field inflationary model up to first order in deviation. The Christoffel symbols and the tensorial quantities are calculated explicitly in function of the cosmic time t.

Ryugu Reference Project: Recommendations from the Measurement Definition Team

Meteoritics &Planetary Science, EarlyView.
Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,
