Introduction: Variable selection is a common technique to identify the most predictive variables from a pool of candidate predictors. Low prevalence predictors (LPPs) are frequently found in clinical data, yet few studies have explored their impact on model performance during variable selection. This study compared the Random Forest (RF) algorithm and stepwise regression (SWR) for variable selection using data from a paediatric sepsis screening tool, where 18 out of 32 predictors had a prevalence < 10%.

Method: A mixed-methods approach was employed, involving a survey of 192 veterinary professionals from various roles and practice types. The survey measured experiences of incivility, individual factors (anxiety, stress, burnout, job satisfaction and turnover intention) and organisational factors (perceived organisational support, social support and civility climate).
Scientists from diverse backgrounds are underrepresented (UR) in academia. This lack of diversity impedes scientific discovery and innovation. UR scientists tend to conduct research on issues relevant to UR populations, including chronic disease prevention and management, and health disparities.

- The study examines how the ratios of carbon, nitrogen, and phosphorus (C:N:P) in ocean particulate matter differ from the standard Redfield Ratio, impacting global carbon storage as these particles sink into the deep ocean.
- Researchers found distinct latitudinal patterns in C:N:P ratios along a transect in the North Pacific, linking these patterns to the composition of macromolecules like proteins, carbohydrates, and lipids in oceanic particles.
- The findings suggest that changes in phytoplankton community structure and nutrient availability are key factors driving variations in these ratios, indicating that physiological acclimation to nutrient supply is likely responsible for the observed latitudinal trends.
Eyes within the marine gastropod superfamily Stromboidea range widely in size, from 0.2 to 2.3 mm - the largest eyes known in any gastropod.
