Support across two generations: children's closeness to grandparents following parental divorce and remarriage.

There has been relatively little research on the role of grandparents as a source of support for children during and following their parents' marital transitions. In this study, we examined children's contact with and closeness to grandparents in different family types (i.e.

A casein kinase I activity is constitutively associated with Nck.

Nck is a 47-kDa cytosolic protein devoid of intrinsic catalytic activity and consisting of Src homology 2 and 3 (SH2 and SH3) domains organized as follows: SH3-SH3-SH3-SH2. Nck is believed to act as an adaptor protein mediating signal transduction initiated by receptor tyrosine kinases (RTKs). Through its SH2 domain, Nck recognizes a specific phosphotyrosine residue on RTKs or on protein substrates of RTKs like insulin receptor substrate-1, the major substrate of the insulin receptor, and through its SH3 domains it interacts with poorly characterized effector molecules.

Sex and mathematical background as predictors of anxiety and self-efficacy in mathematics.

Anxiety and self-efficacy in mathematics as a function of sex and mathematical background were investigated. This study employed an ex post facto 2 x 2 factorial design in which sex and mathematical background were classification variables. It was predicted that men would report lower anxiety scores and higher self-efficacy scores than women and that students with a high mathematical background would report lower anxiety scores and higher self-efficacy scores than those with a low background in mathematics.

Molecular cloning, physical mapping and cross-hybridization of the murine adenovirus type 1 and type 2 genomes.

Murine adenovirus (MAd) type 1 strain FL and type 2 strain K87 genomes were cloned into plasmid pAT153 as HindIII restriction fragments. The MAd-1 and MAd-2 DNA genomes, 30.10 kb and 34.
