Things at Work: How Things Contribute to Performing Work

open access: yesJournal of Management Studies, EarlyView.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.

Environmental drivers of scale morphology in a Canary Island lizard across 3700 m of elevation

open access: yesJournal of Zoology, EarlyView.
Gallotia galloti scale traits are driven by climate and human pressures. High dorsal density correlates with hotter, dryer environments and larger scales with higher sun exposure, while ventral scale variation was associated with isothermality and human influences. These changes highlight morphological responses to environmental conditions.

The nature and formation of silica minerals in eucrite meteorites: Insight into the protoplanetary magma crystallization

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Silica polymorphs in meteorites provide critical constraints on crystallization processes associated with thermal activity in the early solar system. A detailed investigation of silica polymorphs in eucrites (the largest group of achondrites) using cathodoluminescence imaging and laser‐Raman spectroscopy revealed significant variations in the ...

Investigation and reclassification of four mesosiderites—Implications for their formation

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Mesosiderites are rare, differentiated meteorites, so‐called stony‐iron meteorites—they are impact breccias composed of an unusual mix of crustal basalt and pyroxenite, core‐derived metal, but no mantle materials. This odd mixture makes their origin enigmatic and has inspired many different formation theories over the last several decades ...

Petrography of phosphates in CI and CY carbonaceous chondrites

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...
