Dynamical assimilation of surface elevation from tide gauges is investigated to estimate the bottom drag coefficient and surface stress as a first step in improving modeled tidal and wind-driven circulation in the Chesapeake Bay. A two-dimensional shallow water model and an adjoint variational method with a limited memory quasi-Newton optimization...
Cockpit Task Management (CTM) is the initiation, monitoring, prioritization, execution, and termination of multiple, concurrent tasks by night crews. The primary research question posed in the current research is what factors affect task prioritization on the modern day, commercial flight deck. The conventional CTM literature was reviewed as an introduction...
We have measured cosmic ray produced ¹⁰Be (t₁/₂ = 1.5 My) and ²⁶Al (t₁/₂ = 0.72 My) as functions of depth in a core of quartz sandstone bedrock collected in South Victoria Land, Antarctica. These data were used to place limits on the exposure age and erosion rate of the...
The suggestion of climatic instability during the last interglacial period (Eem), based on the bottom 10% of the Greenland Ice core Project (GRIP) isotopic profile, has been questioned because the bottom record from the neighboring Greenland Ice Sheet Project 2 (GISP2) core (28 km away) is strikingly different over the...
The purpose of this study was to investigate the
level of social interaction and social distance or
comfort among five undergraduate ethnic groups (African
Americans, American Indians, Asian Americans, Caucasian
Americans, and Hispanic Americans) at Oregon State
University. Another purpose was to explore the
correlation between the level of social...
Adolescent pregnancy is a major social problem which results in negative psychological, medical, developmental,
economic and educational consequences for both mother and child. A review of the literature examined psychological and sociocultural factors and negative consequences associated with adolescent pregnancy. There has been little research on age specific differences between...
