The majority (67%) of African American youth live in single-parent households, a shift in the family structure that has been linked to increased risk for both internalizing and externalizing problem behaviors. Although the majority of single mothers endorse the assistance of another adult or family member in child rearing, relatively little is known about who is engaged in this nonmarital copar...

Ramos de Almeida, J. M., and Rosado, L. (1972). Archives of Disease in Childhood, 47, 609. Rh blood group of grandmother and incidence of erythroblastosis. Maternal red cells may cross the placental barrier and enter the fetal circulation, and this transfer may cause primary sensitization in Rh-negative girls born to Rh-positive mothers. 60 families were studied. Each family consisted of the gr...

Adults of the cabbage beetle Colaphellus bowringi display a summer diapause in response to the exposure of their larvae to long photoperiods. In the present study, the inheritance of the photoperiodic response controlling summer diapause in C. bowringi by crossing a high diapause strain (D strain) with a laboratory selected nondiapause strain (N strain) was investigated under different photoper...

Starting from a life course perspective, this study aims to gain more insight into mobility patterns of recently separated mothers, focusing especially on moves to the location of their own mother: the maternal grandmother. Separated mothers, having linked lives with their own mothers, may benefit from their practical and emotional support. Additionally, the grandparents' home can be a (tempora...

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...

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...

X-linked agammaglobulinemia (XLA) is a hereditary humoral immunodeficiency that results from Bruton's tyrosine kinase (BTK) gene mutations. These mutations cause defects in B-cell development, resulting in the virtual absence of these lymphocytes from the peripheral circulation. Consequently, this absence leads to a profound deficiency of lg all isotypes, and an increased susceptibility to enca...
