The End of the Observable Infodemic: Privatised Observability and Public Health Monitoring

Policy &Internet, Volume 18, Issue 3, September 2026.
ABSTRACT Infodemiology and infodemic management rest on a premise so foundational that it is rarely stated: health information behaviour leaves traces that researchers and public institutions can observe. This paper argues that the premise is dissolving.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Time's Sentimental Tale: Operationalizing Plot Within the Narrative Policy Framework

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT The Narrative Policy Framework (NPF) has proven to be a successful analytical tool for examining the role of narratives within the policy process; however, the analysis of plot is still understudied. This gap persists due to difficulty in developing valid and reliable measures of plot and a lack of plot operationalizations using longitudinal ...

How Food Geometry and Toughness Influence Ingestive Patterns in Lemurs

American Journal of Primatology, Volume 88, Issue 7, July 2026.
Initial bite placement is influenced by food toughness and geometry. Species‐specific feeding strategies reflect differences in masticatory morphology and functional flexibility. Lemur catta is more likely to use the postcanine tooth row; Propithecus verreauxi prefers anterior biting. ABSTRACT We investigate the extent to which food toughness, geometry,

Long‐term aridity shapes grassland drought resistance and modulates the roles of plant diversity and functional composition

Journal of Ecology, Volume 114, Issue 7, July 2026.
Widely studied stability drivers such as plant diversity and functional composition have only partial explanatory power for short‐term drought resistance of above‐ground productivity in grasslands at a global scale. The abiotic context, particularly long‐term aridity, is crucial for understanding ecosystem responses to rainfall variation and can ...

Mothers against the natural order: Gender representations and desertion of identities in the drama of disinheriting a son in eighteenth‐century Barcelona  

Gender &History, Volume 38, Issue 2, Page 487-496, July 2026.
ABSTRACT The disinheritance of a firstborn son accustomed to the privileges of exclusion has for centuries been a dramatic event for families, especially if the decision was taken by a woman, the son's own mother. Very few dared to do so, because it symbolised a break with the notion of virtuous, compassionate motherhood; it represented a failure to be
