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

Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting
Wildlife Biology, EarlyView.Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to climb, many areas face added pressure to allow recreation, yet studies increasingly demonstrate negative effects of ...

Housing as the Fifth Pillar of the Welfare State: Why Spain Needs Structural Reform
The Political Quarterly, EarlyView.Abstract Spain's ongoing housing crisis reflects the cumulative effects of fragmented governance, underinvestment and financialisation. Despite recent reforms, structural challenges persist, threatening affordability and social inclusion. This article diagnoses the roots of Spain's housing failures, explores pathways for systemic reform and argues that
