Fire regimes approaching historic norms reduce wildfire‐facilitated conversion from forest to non‐forest

Ecosphere, 2018
Extensive high‐severity wildfires have driven major losses of ponderosa pine and mixed‐conifer forests in the southwestern United States, in some settings catalyzing enduring conversions to non‐forested vegetation types.

Exposure to Occupational Inhalants and the Risk of Developing Rheumatoid Arthritis: A Systematic Review and Meta‐Analysis

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint pain, swelling, and stiffness. Although smoking is a well‐established risk factor for RA, the role of occupational inhalants in RA development is less well recognized.

‘Where are the adults?’: Troubling child‐activism and children's political participation

British Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

Activism as a long durée journey: Teachers against the Chilean neoliberal education model

British Educational Research Journal, EarlyView.
Abstract In this paper, I use the idea of purposes of education, particularly subjectification, and the concept of love to explore long‐term teacher activism in Chile. ‘Long‐term activism’ is used to describe an ongoing struggle rather than activism confined to specific moments.

Simulating Grassland Prescribed Fires Using Experimental Approaches [PDF]

Fire Ecology, 2015
AbstractSmall-scale fire approaches, like burn boxes, burn tables, and propane burners, are often used to facilitate experimental control over fire and allow greater replication. We compared characteristics of grassland prescribed fires to three experimental approaches to determine if these approaches simulate prescribed fires.
