Parent-offspring conflict theory predicts the emergence of weaning conflict between a mother and her offspring arising from skewed relatedness benefits. Empirical observations of weaning conflict have not been carried out in canids. In a field-based study on free-ranging dogs we observed that nursing/suckling bout durations decrease, proportion of mother-initiated nursing bouts decrease and mot...

As part of ongoing studies on the neurobiology of socioemotional behavior in the nonhuman primate, we examined the development of mother-infant interactions in 24 macaque monkeys who received either bilateral amygdala or hippocampus ibotenic acid lesions, or a sham surgical procedure at 2 weeks of age. After surgery, the infants were returned to their mothers and reared with daily access to sma...

Individual cells of the budding yeast, Saccharomyces cerevisiae, have a limited life span and undergo a form of senescence termed replicative aging. Replicative life span is defined as the number of daughter cells produced by a yeast mother cell before she ceases dividing. Replicative aging is asymmetric: a mother cell ages but the age of her daughter cells is 'reset' to zero. Thus, one or more...

The diet of pre-school children is determined by the parents and carers.

The mother and one sib showed limitation of hip movements, while radiological criteria for protrusio were found in the mother and 4 of the proband's 8 sibs; only one had complained of pain. At the age of 16 the proband underwent bilateral total replace...

BACKGROUND Few studies have investigated the individual long-term contributions that mothers and fathers make to their children's schooling. AIMS (1) To explore the role of early father involvement in children's later educational attainment independently of the role of early mother involvement and other confounds, (2) to investigate whether gender and family structure moderate the relationshi...

Abstract When interacting with one another, bilingual caregivers and their young children can switch from language to another convey emotion information in meaningful ways. The Specificity Principle (Bornstein, 2017) states that specific setting conditions affect outcomes ways individuals at times. Here we tested three constituents of the Principle: We evaluated how used interaction (setting co...
