Neoconservative social scientists have claimed that fathers are essential to positive child development, and that responsible fathering is most likely to occur within the context of heterosexual marriage. This perspective is generating a range of governmental initiatives designed to provide social support preferences to fathers over mothers; and to heterosexual married couples, rather than to a...

This study hypothesized that father involvement is influenced by mothers' level of involvement as well as by marital conflict, mothers' work hours, and fathers' status as biological or step father. The analysis also tested hypotheses about mother involvement as a potential mediator of the effects of marital conflict and maternal work hours on father involvement, and hypotheses about factors inf...

Fathers make definite contributions to infant development and are now spending more time with their children than in many past decades. This article reviews the most compelling research on the developmental importance of fathers, including father-infant attachment and interaction, and differences between maternal and paternal interaction styles. Results of a long-term study of primary caregivin...

The natural environment is in a state of constant flux and living organisms are perpetually challenged to adapt to these changes. Yet the mechanisms of adaptation, which lead to the development of new characteristics or behaviours, have troubled philosophers and scientists since the days of ancient Greece. In fact, it was not until 1859, when Charles Darwin (1809– 1882) published The Origin of ...

Using data from a racially and ethnically diverse sample of low-income mothers of 2-year-old children participating in the Early Head Start Research and Evaluation Project (N = 883), the authors examined fathers' education and employment, mother-father relationship, and mothers' relationships with kin in the household to explain variation in nonresident father involvement across racial and ethn...

The Journal of Cell Biology instituted electronic submission of manuscripts in December, 2001. Our brief experience in handling the review process electronically has raised an important issue regarding the manipulation of digital images that I would like to bring to the attention of the members of the cell biology community, who are our authors and reviewers. Our concern is not that the manipul...
