The relative rates of hydrogen abstraction from 1-phenylalkanes and a,w-diphenylalkanes using N-bromosuccinimide and bromotrichloromethane were determined at 70°C. In both cases the reactions were photoinitiated. Only benzylic bromination was observed. The 1-phenylalkanes reacted with both reagents to give rates largely independent of substrate. Similarly, the rate of the reaction between...
The purpose of this research was to investigate the relationship
of internality and structural variables such as sex, socio-economic
status, and academic achievement to the extensiveness and effectiveness
of vocational exploratory behavior during college.
The sample utilized in this study consisted of 108 male and
female seniors who were in...
From 1996 through 1998 I collected mature female black rockfish off Oregon and examined ovaries and otoliths to estimate weekly, age-specific larval production. In all reproductive seasons, older black rockfish extruded larvae earlier in the season, followed by progressively younger fish. Each year, beginning in May, I collected young-of-the-year (YOY)...
Perceived discrimination has been a topic that has been explored extensively in various different countries and regions (Awad 2010; Litchmore and Safdar 2015; Godley 2018; Dixon 2019). A growing concern for affected groups has prompted many of these studies, as perceived discrimination has been found to potentially negatively impact one's...
Geostatistical linear interpolation procedures such as kriging require knowledge of the
covariance structure of the spatial process under investigation. In practice, the covariance of the
process is unknown, and must be estimated from the available data. As the quality of the
resulting predictions, and associated mean square prediction errors, depends...
Tide gauges are designed to measure changes in water level relative to land. However, vertical motions of the earth's crust manifest themselves as apparent water level changes in tide gauge records. These crustally induced changes are often small in amplitude relative to the wide range of oceanic processes which affect...
A formalism is presented for quantifying the sampling error of an arbitrary linear estimate of a time-averaged quantity constructed from a time series of irregularly spaced observations at a fixed location. The method is applicable to any irregularly sampled time series; it is applied here to satellite observations of chlorophyll...
This assessment outlines an enhanced planning approach for West Coast estuaries that incorporates an evaluation of the regional context for estuarine conservation and recommends an approach to site-scale planning with more focus on ecological processes and functions.
