Recent advances in courtship theory emphasize day-today
interaction and the environment in which interaction
takes place as critically important in the understanding of
relationship development. The purpose of this study was to
determine the influence of college course assignments on
time spent in relationship activities and, similarly, the
influence of...
The studies described here introduce a model for residue preservation on stone tools. They simulate stone tool manufacture in order to define parameters important for the study of DNA residues. Microscopic examination of stone tools has identified microcracks that trap DNA and protein from animal blood cells. Thorough investigation of...
Although dam construction has been an integral tool in development initiatives for nearly a century, dams can have significant negative impacts on local residents, particularly those who are permanently displaced from their homes and must be resettled elsewhere. Dams have unique impacts on indigenous peoples. As a result, many dam...
The purpose of the present study was to describe the process of
premarital relationship dissolution. This description entailed
typologizing relationships on the basis of their trajectories to
involvement and eventual dissolution. One hundred individuals who had
been involved in a serious relationship that had broken up within the
past 12...
Armillariella mellea (Vahl. ex Fr. ) Karst. was grown aseptically
in hazel stems (Corylus cornuta var. californica) which were used in
the forest to infect 290 ponderosa pines (Pinus ponderosa Laws.)
which had been "stressed" in five different manners plus two control
groups. All trees were inoculated twice giving a...
The regulation of behavior is a major issue in early childhood development, with important implications for children’s adaptive and maladaptive developmental outcomes. Emerging research suggests that the degree of successful self-regulation depends upon the efficiency of the child’s attentional system and that the ability to focus and sustain attention supports...
Eight male college students served as subjects in an investigation
to establish a procedural model for research of individual motor
units during sustained isometric contractions. Teca TE-4 electromyograph
system with needle electrode provided electrical potential
recordings from active muscle fibers in the right biceps. Various
experimental procedures were tested to...
