We analyzed data from the historic population of the Krummhörn (Ostfriesland, Germany, 1720-1874) to determine the effects of grandparents in general and grandmothers in particular on child mortality. Multilevel event-history models were used to test how the survival of grandparents in general influenced the survival of the children. Random effects were included in some models in order to take ...

OBJECTIVES We used McCubbin's Resiliency Model of Family Stress, Adjustment and Adaptation ( McCubbin, Thompson, & McCubbin, 2001) to examine how demographic factors, family stress, grandmother resourcefulness, support, and role reward affect perceptions of family functioning for grandmothers raising grandchildren, grandmothers living in multigenerational households, and grandmothers not caregi...

This article reports findings from two exploratory qualitative studies of the relationship between age norms, family role transitions, and the caregiving responsibilities of mothers, grandmothers, and great-grandmothers in multigeneration African American families. Families defined as having "normative on-time" transitions (n = 23) to the roles of mother, grandmother, and great-grandmother were...

Biologists use genetic relatedness between family members to explain the evolution of many behavioural and developmental traits in humans, including altruism, kin investment and longevity. Women's post-menopausal longevity in particular is linked to genetic relatedness between family members. According to the 'grandmother hypothesis', post-menopausal women can increase their genetic contributio...

Angela is a 34-week neonatal patient born at 27 weeks gestation with a birth weight of 2 pounds. She has had a rough course in the Neonatal Intensive Care Unit. For the past two and a half weeks, Angela’s saturation rate has been in the low thirties, forties, and fifties. Whether she is on high frequency ventilation or regular ventilation, there seems to be no appreciable difference in saturati...

The centres on strong, abiding relationship between grandmother. Their anchor point for their survival in new unhappy world they find themselves in. As an anthropologist displacement, this short attempt to tell crisis, displacement conflict through fictional...

Prior tests of the grandmother hypothesis have suggested that postreproductive female Japanese macaques, Macaca fuscata, do not significantly improve the survivorship of their descendents. However, not all postreproductive females are grandmothers, and not all grandmothers are postreproductive. In this study we looked at the daughters and grandchildren of 70 female Japanese macaques to assess t...

We do not dispute the possibility of the existence in the brain of “grandmother cells”, which are very finely tuned neurons that fire only in the presence of specific objects or categories. However, we question the causal efficacy of such neurons at the functional or behaviour level. We claim that, even though very familiar items, such as “my grandmother”, may well have associated grandmother n...
