“Seen Again”: Ethnography, Immersive Technologies, and Temporality in the Siberian Collections at the Pitt Rivers Museum

Museum Anthropology, EarlyView.
ABSTRACT This paper proposes Virtual Reality (VR) and 360 film as promising fieldwork tools for addressing problematic temporalities in ethnographic museums and for collaborating with communities of origin. Focusing on the Maria Czaplicka Siberian collections at the Pitt Rivers Museum, Oxford, we examine how previous methods of display marginalized the

The simplicity of physical laws

Noûs, EarlyView.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

A Three‐Stage Model of the Maturation of Nascent Policy Subsystems Toward Stable Advocacy Coalitions, With Evidence From the UK's Response to COVID‐19

Policy Studies Journal, EarlyView.
ABSTRACT Policy subsystems are comprised of competing advocacy coalitions, in which public and private political actors with shared belief systems learn from each other and coordinate their strategies in the pursuit of influencing policy making in their favor.

Embracing the politics of transformation: Policy action as “battle‐settlement events”

Review of Policy Research, EarlyView.
Abstract Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations.
