Placer
Definition:
(n.) One who places or sets.
(n.) A deposit of earth, sand, or gravel, containing valuable mineral in particles, especially by the side of a river, or in the bed of a mountain torrent.
Example Sentences:
(1) Placers were both the most advantaged socioeconomically and held the most positive attitudes toward adoption, while young women who never considered adoption were the least advantaged and held the least favorable attitudes.

(4) Using FACES II as the measure of family cohesion and adaptability, it was hypothesized that: (1) adolescent parents or placers would describe their families as being less functional than adolescent norms, (2) adolescents who placed their children for adoption would describe their families as being more functional than adolescents who parented their children, and (3) adolescents from the more functional families would report greater satisfaction with the placement decision than those from less functional families.
(5) Using FACES II as the measure of family cohesion and adaptability, it was hypothesized the: 1) adolescent parents or placers would describe their families as being less functional than adolescent norms; 2) adolescents who placed their children for adoption would describe their families as being more functional than adolescents who parented their children; and 3) adolescents from the more functional families would report greater satisfaction with the placement decision than those from less functional families.
(6) However, caution should be used when comparing our results obtained in "clear" water to field situations, because speciation and toxicity of these inorganics may be altered in the presence of sediments suspended by placer mining activities.
(7) Results indicate that Hypothesis 1 was supported, but contrary to Hypothesis 2, there were no significant differences in family functioning between placers and parents.
(8) Based on the results of the present study, estimated no-effect concentrations of arsenic and mercury, but not cadmium, chromium, gold, nickel, selenium, or silver, are close to their concentrations reported in streams with active placer mines in Alaska.
(9) Adolescents who placed their babies had significantly lower scores on the role-reversal measure, but the differences between keepers and placers on the expectations, empathy, and corporal punishment dimensions were not significant.
(10) The acute toxicity of nine inorganics associated with placer mining sediments to early life stages of Arctic grayling (Thymallus arcticus), coho salmon (Oncorhynchus kisutch), and rainbow trout (O. mykiss) was determined in soft water (hardness, 41 mg liter-1 CaCO3) at 12 degrees C. The relative toxicities of the inorganics varied by four orders of magnitude; from most toxic to least toxic, the rank order was cadmium, silver, mercury, nickel, gold, arsenite, selenite, selenate, and hexavalent chromium.
(11) Placers consistently reported that their choice to place their babies rather than parent would increase the likelihood of outcomes such as continuing with school, having enough money to live comfortably and benefiting the baby's emotional development, while those young women who did not consider adoption tended to feel that these outcomes would be more likely if they parented, or that the likelihood of the outcomes would not be affected by their choice.
