Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Using structured decision making to evaluate the tradeoffs of selective fish passage

open access: yesConservation Science and Practice, EarlyView.
Abstract Dams have dramatically altered rivers and are a major contributor to native fish population declines. However, many dams serve important ecological, social, and economic functions, such as flood control, invasive species control, and provision of recreational opportunities.

Biocultural Approaches in the Society for the Anthropology of Food and Nutrition: A Reflection on 50 Years

open access: yesCulture, Agriculture, Food and Environment, EarlyView.
ABSTRACT On the occasion of SAFN's 50th anniversary I reflect on the development of biocultural and human evolutionary approaches to human diet and nutrition. I maintain that SAFN and its predecessors the Committee (1974–1987) and then Council on Nutritional Anthropology (1987–2004) have modeled, fostered, and advanced biocultural work in anthropology ...

Block scheduling in practice: An optimal decomposition strategy for nonidentical operating rooms

open access: yesDecision Sciences, EarlyView.
Abstract We develop and implement a Master Surgery Schedule for a real‐life hospital, assigning operating room (OR) time to surgical specialties over a multi‐week horizon. Through action research, we identify a critical operational challenge: the issue of split blocks. Split blocks allow two specialties to share an OR on the same day—one in the morning,

Does nature shape risk preferences? Evidence from Chile, Norway, and Tanzania

open access: yesEconomic Inquiry, Volume 63, Issue 2, Page 568-590, April 2025.
Abstract Does exposure to a more risky environment affect risk preferences? Going beyond single‐case study evidence, we report results from five surveys conducted in three countries and link this with administrative data to study whether a link between exposure and preferences is detectable and widespread. We find no evidence for endogenous preferences
