Modeling and prediction of surgical procedure times [PDF]
Accurate prediction of medical operation times is of crucial importance for cost efficient operation room planning in hospitals. This paper investigates the possible dependence of procedure times on surgeon factors like age, experience, gender, and team ...

Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest
Integrative Zoology, EarlyView.Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

fishmax: An R package for Bayesian estimation of maximum body size in animals
Methods in Ecology and Evolution, EarlyView.Abstract Maximum body size is a key trait of an animal species, determining its population dynamics, productivity and interactions with other species and the environment. For fish in particular, the maximum body length or Lmax$$ {L}_{\mathrm{max}} $$ correlates strongly to other life history parameters and is commonly used in ecological models and ...

Testing Special Cases of the GB2 Distribution: Comment and an Extension
We extend earlier work (Griffiths and Hill, 2025) by pointing out that a score test developed by Prentice (1975) for testing whether a normal distribution is an adequate representation of the log of a GB2 random variable is suitable for testing whether a

Methods in Ecology and Evolution, EarlyView.Abstract Trait‐based ecology increasingly relies on measures of intraspecific trait variability to estimate how trait diversity within species varies across species and environmental gradients. Yet variance and related metrics are often interpreted without considering their intrinsic dependence on the mean, as described by the empirical Taylor's power ...

Mitigating policy uncertainty: What financial markets reveal about firm‐level lobbying
American Journal of Political Science, EarlyView.Abstract Elections can lead to substantial policy changes and, thus, are a significant source of risk. Firms can respond to such policy uncertainty by lobbying, but it is hard to quantify whether they do so and, if so, how much lobbying benefits them. We construct a new dataset and leverage investors’ expectations of variability in stock returns in the
