The Kichwa of Sarayaku Case at the Inter‐American Court of Human Rights: Legal Pluralism, Identity and Citizenship in a Context of Extractivism

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT This article examines the tension between a universal approach to law and the recognition of indigenous peoples' rights at the Inter‐American Court of Human Rights. The struggle for citizenship in a situation of extractivism and land dispossession demonstrates how identity is mobilized to obtain and attribute rights. The focus of this study is

Feminist Agroecology and Criollo Hens: Women's Everyday Resistance in Colombia

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Industrial poultry technologies and processes are reshaping the knowledge, practice and agrobiodiversity of criollo (Gallus domesticus) or backyard hen keeping, as well as outcompeting this livelihood in formal markets. This transition undermines women's autonomy and socio‐economic resilience by engendering dependence on market inputs ...

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Water and hydroxyl on asteroid Bennu: Reconciling remote observations with OSIRIS‐REx sample analysis

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract This study investigates the spatial distribution and spectral characteristics of the broad hydration feature near 3 μm across the surface of asteroid (101955) Bennu using OVIRS (OSIRIS‐REx Visible and InfraRed Spectrometer) data. We analyzed multiple global OVIRS data sets obtained at different times throughout the Bennu day, revealing ...

Assessing the analytical capabilities of handheld laser‐induced breakdown spectroscopy (hLIBS) on corroded iron objects of possible meteoritic origin

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Despite meteorites having been recognized as the source of iron in some ancient iron artifacts, few archeological irons have been analyzed so far, as invasive methods are precluded. In this work, four iron knives and one axe collected near Guelmime and Imilchil (Morocco) were investigated by advanced analytical techniques, including handheld ...

Thermal history, collisional history, and structure of the CK‐chondrite parent body

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.

Chondrule size averaging in two and three dimensions

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Chondrule sizes are an important discriminant of chondrite groups and chondrule formation theories. Yet most studies report 2‐D sizes without attempting the somewhat tedious corrections to 3‐D proposed in the past literature. I show here that 3‐D size averages can be simply calculated directly from 2‐D averages of appropriate powers of sizes ...
