‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

The Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.

Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

Exploring the Genetic Variation of Fleece and Crutch Shedding in Sheep, Recorded at Different Times Within and Across Age Classes

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The global value of wool from coarse woolled sheep continues to decline, prompting producers to seek alternatives that reduce or eliminate the need for shearing. Several sheep breeds naturally shed their fleece in response to photoperiod, and these breeds are being crossed with populations that have high genetic merit for traits such as ...

Histological analysis of incremental markings and crown growth characteristics in mandibular first molars of the red fox, Vulpes vulpes (Canidae, Mammalia)

Journal of Anatomy, EarlyView.
This paper histologically analyzed incremental markings in dental enamel of red fox and grey wolf. Our results demonstrate that previous studies have misidentified these markings, which led to miscalculation of dental growth parameters. Abstract The present study analyzed incremental markings in the enamel of eight mandibular first molars (M1) of red ...
