Ecological examples of nonstationarity, nonlinearity and statistical interactions in dynamic structural equation models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Ecologists are adapting structural causal modelling for spatial, phylogenetic and time‐series analysis. However, ecological extensions of path analysis and structural equation models (SEM) typically assume that interactions among variables are stationary, linear and additive, while ecological and evolutionary dynamics are often nonstationary ...

Modelling Patterns of Past Inundation Processes Combining Geoarchaeology and Morphometric Hydrological Analysis in the Shashe‐Limpopo Basin, South Africa

open access: yesArchaeometry, EarlyView.
ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the

Some culture is hiding in plain sight in research on child development

open access: yesBritish Journal of Developmental Psychology, EarlyView.
Abstract Child development is cultural in nature, yet a divide persists between a (cross‐)cultural developmental science niche alongside a seemingly a‐cultural mainstream. In particular, childhood research relying on convenience sampling in often Western, post‐industrial (i.e., WEIRD) societies rarely ventures into issues of culture and context ...

Discriminant validity and interrelations of conceptual and procedural knowledge in fractions and algebra: Evidence from confirmatory factor analysis

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Background Conceptual and procedural knowledge are two distinct types of mathematical knowledge. Measuring them with sufficient discriminant validity is challenging because they are typically highly correlated. Prior studies have demonstrated discriminant validity of paper‐and‐pencil measures separately for fractions and algebra.

Connections between the basic local independence model and true and error models in the study of preference

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Two classes of probabilistic models are compared: the true and error (TE) type models and models in the family of the basic local independence model (BLIM). The former finds applications in the study of human preference, whereas the latter has been developed within the theory of knowledge structures with the aim of producing knowledge ...
