US teens overestimate risk for early death. The purpose of this study was to identify factors associated with an adolescent's change from early death perception to a belief in living into adulthood. Data are from 9140 adolescents participating in waves 1 (1995) and 2 (1996) of the National Longitudinal Study of Adolescent Health. Logistic regression models were used to determine contexts of hea...

In order to investigate the temporal characteristics of cognitive processing, we apply multivariate phase synchronization analysis to event-related potentials. The experimental design combines a semantic incongruity in a sentence context with a physical mismatch (color change). In the ERP average, these result in an N400 component and a P300-like positivity, respectively. Synchronization analys...

with a range of problem outcomes during childhood, adolescence and adulthood. Adults who were victims of child sexual abuse often fear sex, distrust their sex partners, have decreased sexual drive and have multiple superficial sexual relationships.1 Some children who were sexually abused have been found to engage in sexualized behavior (e.g., atypical sexual play with dolls and playmates, or ex...

During Leg 204, we cored and logged nine sites on the Oregon continental margin to determine the distribution and concentration of gas hydrates in an accretionary ridge and adjacent slope basin, investigate the mechanisms that transport methane and other gases into the gas hydrate stability zone (GHSZ), and obtain constraints on physical properties of gas hydrates in situ. A three-dimensional s...

We compared the NOAA Southwest Fisheries Science Center’s Environmental Research Division (formerly Pacific Fisheries Environmental Laboratory: PFEL) coastal upwelling indices along the northern Baja California coast with those derived from winds measured by coastal meteorological stations and estimated by the QuikSCAT satellite. With the exception of the PFEL series at 33 ̊N, the three data set...

F is an important trace element for bones and teeth. The protective effect of F against dental caries is well established. Urine is the prime vehicle for the excretion of F from the body; however, the relationship between F intake and excretion is complex: the derived fractional urinary F excretion (FUFE) aids understanding of this in different age groups. The present study aimed to investigate...
