The adult Drosophila midgut contains multipotent intestinal stem cells (ISCs) scattered along its basement membrane that have been shown by lineage analysis to generate both enterocytes and enteroendocrine cells. ISCs containing high levels of cytoplasmic Delta-rich vesicles activate the canonical Notch pathway and down-regulate Delta within their daughters, a process that programs these daught...

While historically under-studied in comparison to other family relationships, the fatherdaughter relationship is an important dyad within the family sytem and has been associated with a number of significant psycho-social developmental outcomes for women as they grow from young girls to young adults. Of particular importance is the quality of the emotional connection shared by fathers and daugh...

PURPOSE To expand knowledge concerning the significance of kin relationships in caregiving, this study assessed predictors of the timing of institutionalization for persons with dementia. The focus was on whether use of adult day care by wives and daughters holds the same implications for placement. DESIGN AND METHODS Guided by a caregiving stress process model, primary objective and subjecti...

This paper focuses on assistance that externally-resident daughters provide for their aging parents in rural Tibet, China, to challenge the notion that rapid modernization invariably threatens family-based care systems for the elderly. The authors discuss social and economic changes associated with modernization that have created new opportunities for parents to send daughters out of their nata...

Models suggest that dispersal patterns will influence age- and sex-dependent helping behavior in social species. Duolocal social systems (where neither sex disperses and mating is outside the group) are predicted to be associated with mothers favoring sons over daughters (because the latter are in reproductive competition with each other). Other models predict daughter-biased investment when be...

The aim of this study, carried out before the beginning of human papillomavirus (HPV) vaccinations as a National Immunization Program (NIP) in Korea in 2016, is to assess the ranges of perceptions and personal experience and their influences on attitudes regarding HPV vaccinations of children, among mothers of adolescent (9-14 years of age) daughters in Korea. From November 2015 to February 201...

In the U.S., there is evidence of a Trivers–Willard (T–W) effect in educational attainment, such that the sons of high status fathers attain more education than the daughters, and the daughters of low status fathers attain more education than the sons. This paper seeks to uncover the mechanisms by which this T–W effect occurs. Data are from the High School and Beyond Study by the U.S. National ...
