Purpose of the Study: The purpose of this study was to determine the effects of birth
order, sex, and the interaction of birth order and sex on the self concept
as measured by the 29 mean scores of the Tennessee Self-
Concept Scale (TSCS). Procedures: This research is restricted to...
During 1969-1971 I studied patterns of resource allocation and
behavioral interaction among Brandt's Cormorants, Pelagic Cormorants,
Common Murres and Pigeon Guillemots in the area of a breeding
colony on Yaquina Head on the central Oregon coast. Extensive studies
of the breeding colony were combined with detailed observations of the
distribution,...
Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...
The Oregon Department of Forestry, in cooperation with the Oregon Department of Land Conservation and Development, offers this publication as a guide for cities and counties to use in the development of urban forest practice regulations.
Common methods for assessment of surface checking in decorative plywood panels rely on manual handling and visual inspection of specimens, a laborious procedure practically limiting the number of materials and variables that may be considered within one project. In this study, a new automated optical method for detection and measurement...
Calculation of vector winds from spaceborne fan-beam scatterometers requires that backscatter measurements from different antennas be relatively calibrated to high accuracy. A method is developed to perform postlaunch antenna calibration using global mean ocean backscatter measurements in conjunction with estimates of the statistical distribution of near-surface wind velocity and the...
In an environment of limited resources and expanded management expectations, fisheries regulators face hard decisions about how intensively to regulate different stocks. The Fishery Management Councils are required to regulate harvest of all stocks in a sustainable manner, but have discretion on how much regulatory effort to invest in individual...
This paper discusses the development of a new GIS extension named the Topographic Compartment Analysis Tool (TopCAT), which compares sequential digital elevation models (DEMs) and provides a quantitative and statistical analysis of the alongshore topographical change. TopCAT was specifically designed for the morphological analysis of seacliffs and beaches but may...
Unconditioned responding (UCR) to a naturally aversive stimulus is associated with defensive responding to a conditioned threat cue (CS+) and a conditioned safety cue (CS-) in trauma-exposed individuals during fear acquisition. However, the relationships of UCR with defensive responding during extinction training, posttraumatic stress disorder (PTSD) symptom severity, and fearful...
