Medical trauma in context: Recognizing and addressing medically induced posttraumatic stress disorder in adults

Journal of Traumatic Stress, EarlyView.
Abstract Potentially traumatic medical events (PTMEs) occur across acute and chronic illness trajectories, such as invasive procedures, intensive care, and life‐threatening diagnoses. Emerging evidence suggests that approximately 20% of individuals exposed to PTMEs develop posttraumatic stress disorder (PTSD).

Sampling for Socially‐Inclusive Adoption Studies (SSAS): A new interdisciplinary sampling method for DNA‐fingerprinting‐based crop varietal adoption studies

PLANTS, PEOPLE, PLANET, EarlyView.
DNA fingerprinting is becoming the standard measurement procedure in crop adoption studies in the Global South, yet the lack of systematic and intentional sampling regarding which farmer to go to the plot with may bias results from these methods. We introduce a methodological innovation, Sampling for Socially Inclusive Adoption Studies (SSAS), to offer
