A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

New opportunities for grassland species in warming temperate winters

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperate winters are getting warmer, the length of the growing season is increasing and mid‐winter fluctuations of warm and freezing temperatures are more frequent. Although typically winter dormant, some herbaceous perennials can maintain or grow green leaves during ...

‘Mere Amateurs’? Elementary Teachers and the Making of Scientific Authority in the British Child Study Movement

open access: yesHistory, EarlyView.
Abstract This article offers new perspectives on the relationship between elementary teaching, scientific expertise and the professionalization of the human sciences. Previous scholarship has demonstrated the ready existence of ‘amateur’ science societies in the nineteenth century where cross‐class exchanges were common.

Unnatural Wills: Inheritance Disputes and Inequality

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT Within the conceptual frame of relational economic sociology, inheritance disputes are a canonical form of relational mismatch. But the social patterning of relational mismatches, and their various ties to inequality, remain murky. In this paper, I examine all known inheritance disputes in Dallas from 1895–1945 within their social context to ...
