The challenge feminist scholarship posed to family studies has been largely met through the incorporation of research on gender dynamics within families and intersectional differences among them. Despite growing attention to gender as performance and power in more diverse families, the more difficult work of understanding the dynamics of change among institutions including the family and using ...

A biometrical genetical analysis of IgG, IgM, and IgA levels in 134 sets of twins is reported. High heritabilities, around .8, are found for all three immunoglobulin levels, and possible reasons for lower heritabilities found in family studies are discussed. There is evidence for genetical dominance tending to decrease IgM and IgA levels, but there is no evidence for the importance of family en...

OBJECTIVE Several components of event-related potentials--P50 suppression, P300 amplitude and latency, and mismatch negativity--have been proposed as potential endophenotypes for schizophrenia on the basis of family studies. The present study used a twin design to estimate the extent of genetic overlap between these indices and the liability to schizophrenia. METHOD The authors measured misma...

prevention efforts [1]. In this sample of Greenland Inuit where both HIV and undernutrition remain uncommon, the risk of developing TB was markedly higher in persons with co-existing diabetes than in persons without. The very high risk associated with diabetes suggests potential reduction in the Greenland TB incidence rates through incorporating diabetes control and prevention in TB prevention ...
