Cyclic combing of untreated and bleached human hair: Analysis of the time‐dependent breakage of hair through recording the formation of fibre fragments

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 2, Page 201-210, April 2026.
One important aspect of daily hair grooming routines is whether, after combing, conspicuous numbers of broken hairs are observed. Machine‐based cyclic combing of hair tresses serves as a good indicator for early hair breakage and as a suitable measure to determine the effect of an ingredient/product/process on hair ‘strength’.

An Explanation of Path Analysis and Recommendations for Best Practice

open access: yesContemporary Accounting Research, Volume 43, Issue 1, Page 290-313, Spring 2026.
ABSTRACT Path analysis has become increasingly popular, but many studies do not show a deep understanding of how path analysis works or the assumptions on which it relies. In this paper, we explain that path analysis is statistically equivalent to either OLS when the researcher assumes uncorrelated errors, or instrumental variable (IV) estimation when ...

Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr

open access: yesJournal of Animal Ecology, Volume 95, Issue 2, Page 359-376, February 2026.
Our study reveals that brook charr adopt distinct ‘warm’ and ‘cool’ behavioural tactics to balance foraging and thermal stress in stratified lakes. By linking fine‐scale thermal movements to morphology, we show how temperature‐driven habitat use promotes individual specialization and potential ecotypic divergence under climate change.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

Progestagens Monitoring in 147 Mares in Order to Induce Foaling With Oxytocin

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Parturition was induced when the progestagens concentration fell of about 50% within 24 to 48 h. Induction was performed at 9 p.m. in 93 mares that followed the rule of the drop of progestagens, by a single IM oxytocin injection from 10 to 50 UI according to the weight of the mare (120 to 900 kg).
