An Explanation of Path Analysis and Recommendations for Best Practice

Contemporary Accounting Research, EarlyView.
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 ...

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

International Journal of Cosmetic Science, EarlyView.
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’.
