Asymptotic properties of cross‐classified sampling designs
Abstract We investigate the family of cross‐classified sampling designs across an arbitrary number of dimensions. We introduce a variance decomposition that enables the derivation of general asymptotic properties for these designs and the development of straightforward and asymptotically unbiased variance estimators.

ABSTRACT This article introduces a methodology for analyzing comics drawn by students in the context of a science inquiry. Within a pragmatist situated semiotic approach, comics created by the students in the context of a science inquiry are semiotic representations reflecting learning viewed as a sense‐making inferential process via the building of a ...

Cache‐Cache: Dans les souffles du Grand Fleuve…
ABSTRACT Between ventriloquism and divination, devotion and consecration, an old and sublime marine game unfolds each day, with living breaths shared in the waters of the great river. In Tadoussac, on the north shore of the St. Lawrence Estuary, at the mouth of the Saguenay, the rumor of whales has long resonated.

Penetration enhancement effects of topically applied crosslinked hyaluronic acid
Cross‐linked hyaluronic acid (HA) was demonstrated to enhance the topical delivery of a variety of hydrophilic actives into the skin. This phenomenon was observed for both small molecules and macromolecules, the latter of which was analysed with MALDI mass spectrometry imaging (MALDI‐MSI).

Les besoins protéiques et énergétiques du veau de boucherie : détermination et facteurs de variation
Les connaissances sur les besoins nutritionnels des veaux de boucherie ont peu évolué depuis la parution des références formulées par Toullec (1988). Ces dernières ont été élaborées à partir de travaux antérieurs et définissent les besoins en protéines ...

Restricted Tweedie stochastic block models
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Rank‐based estimation of propensity score weights via subclassification
Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.
