This paper considers some contemporary demographic, occupational, and ideological challenges to the American family and their implications for future developments. Recent discoveries in biology are also touched upon with a view to their effects on reproductive and marital behavior. Both short range and longe range changes are examined, as is the receptivity of various segments of the American public to these changes.

AbstractModeling the data from extended twin pedigrees allows the estimation of increasing complex covariance relationships in which the effects of cultural transmission, nonrandom mating and genotype x environment covariation can be incorporated. However, the power to detect these effects in existing data sets has not yet been examined. The present study examined the effects that different family structures (i.e., the ratio of MZ to DZ families and the importance of cousins vs. avuncular relatives) have on statistical power. In addition, we examined the power to detect genetic and environmental effects within the context of two large data sets (VA30K and the OZVA60K). We found that power to detect additive genetic and cultural transmission effects were maximized by over sampling MZ families. In terms of ascertainment, there was little difference in power between samples that had focused on recruiting a third generation (the children of twins) versus those that had focused on recruiting the siblings of the twins. In addition, we examined the power to detect additive and dominant genetic effects, cultural transmission and assortative mating in the existing VA30K and OZVA60K samples, under two different models of mating: phenotypic assortment and social homogamy. There was nearly 100% power to detect assortative mating and cultural transmission, against a background of small additive and dominant genetic and familial environmental effects. In addition, the power to detect additive or dominant genetic effects quickly asymptoted, so that there was almost 100% power to detect effects explaining 20% or more of the total variance. These results demonstrate that the Cascade model has sufficient power to detect parameters of interest in existing datasets. Mx scripts are available from www.vipbg.vcu.edu/~sarahme/cascade.

When individuals participate in health care research, the choice often affects the entire family. Researchers are responsible for protecting participants and minimizing any burdens the research may place on them. Resources to educate potential study participants about these issues from a family perspective are lacking. A family-focused, evidence-based resource was created for individuals and families to prompt discussion prior to their consenting to enrollment in research. The resource includes key relevant questions to consider related to their study participation and was revised based on input from family nurse scientists and a hospital-based family advisory group. This resource raises awareness of the importance of employing a family lens when designing research and during the recruitment and enrollment of participants. Adopting a family lens in health care research will support the participant's ability to make an informed choice regarding participation and may ultimately enhance the experience of participants and their families and study outcomes.

Abstract
The German Family Panel pairfam is a multidisciplinary, multi-actor, longitudinal study of partnership and family dynamics in Germany. The present paper illustrates the wide analytical potential inherent, in the annually growing pairfam dataset by summarizing published analyses of pairfam data on the topics of partnership, parenthood, and intergenerational relationships. Since the panel is uniquely rich due to its longitudinal and multi-actor design, this selection of publications also provides a concise review of current developments in the sociology of family and partnership.
