What Exactly Are You Inferring? A Closer Look At Hypothesis Testing, Mc Newman

VIMS Articles

This critical review describes the confused application of significance tests in environmental toxicology and chemistry that often produces incorrect inferences and indefensible regulatory decisions. Following a brief review of statistical testing theory, nine recommendations are put forward. The first is that confidence intervals be used instead of hypothesis tests whenever possible. The remaining recommendations are relevant if hypothesis tests are used. They are as follows: Define and justify Type I and II error rates a priori; set and justify an effect size a priori; do not confuse p(E vertical bar H-0) and p(H-0 vertical bar E); design tests permitting Positive …

Consequences Of Sediment Flux: Escape Or Entrapment?, Maynard M. Nichols

VIMS Articles

Estuaries exhibit a full range of flux that extends from escape of sediment into the ocean to complete entrapment and storage within the system. The trapping efficiency of U.S. East Coast estuaries is compared with respect to long-term infilling and present- day flushing velocity , volumetric capacity , and circulatory mixing. It was found that entrapment prevails in many northern estuaries as a consequence of high volumetric capacity , low flushing velocity , and the nearly closed circulation. In many estuaries, channel deepening has reversed the " normal" trend of long-term infilling. Although dredging enhances circulatory entrapment, large-scale ocean dumping …

Storage Efficiency Of Estuaries, Maynard M. Nichols

VIMS Books and Book Chapters

Estuaries or the U.S. Atlantic coast exhibit a range or storage efficiencies from complete storage to partial by-passing through the system. Efficiency, I.e. the ratio or sediment accumulation to river Input rate, ranges 0.7 in the Altamaha River, Ga. to 7.6 In the Choptank River, Md. Northern estuaries trap and store the bulk or their river input In addition to large amounts or sediment supplied from other sources. Southern estuaries accumulate major sediment loads in marshes and allow partial escape through channels to the sea.

The storage efficiency or difrerent estuaries is compared with respect to key factors that can …

A Theory Of Associative Detachment, Susan Elizabeth. Haywood

Dissertations, Theses, and Masters Projects

In this thesis a theory of associative detachment (A('-) + B (--->) AB + e) is presented. The theory is based on the close-coupling theory of Wang and Delos, but is more general in that final states of the nuclei (AB) are treated quantum mechanically. This is necessary since the molecule may be in any one of several vibrational states. The Schroedinger equation is reduced to an infinite set of coupled equations using carefully chosen assumptions. The coupled equations are uncoupled and the resulting equation for the wave function of the negative ion is solved to zero and first …
