National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Hunting in the Ghaznavid State: Courtly Culture, Military Practices and Political Power

open access: yesHistory, EarlyView.
Abstract Hunting occupied an important place in the royal court culture of the Ghaznavid state (963–1186 CE). Ghaznavid hunting culture developed through the interaction of Turkic‐Islamic political traditions, Persianate models of kingship and local ecological settings. Rather than constituting a fully formalized institution, Ghaznavid hunting practice
