"This report concerns one aspect of the marina permit evaluation process: water quality impacts related to marina circulation and flushing efficiency. These physical properties vary with the wind, tide range, water density and physical dimensions of a marina. Water quality is affected by the degree of flushing, and sediment redistribution...
The purpose of the workshop was to exchange information on sampling procedures, research methodologies, preparation and
interpretation of specimen material, terminology, and the application
and significance of findings, emphasizing the relationship of dendrochronology procedures to fire history interpretations.
Life history attributes and apparent distributional
patterns suggest that Plethodon dunni exists as small, semi-isolated
populations throughout its range. Isozyme and morphological
variation in this species was examined to determine
any possible geographic trends.
Starch gel electrophoresis was utilized to examine
genetic variation at 24 isozyme loci in 287 individuals...
The "Framework for Determining the Suitability of Undeveloped
Land for Use as Cropland" is a decision-making format to assist private
and governmental agency decision makers in categorizing undeveloped
lands, which have been identified as having potential for conversion
to cropland, as to their suitability for use as cropland. The
Framework...
The interference of sulfide with the colorimetric determination of
nitrite, by the method of Bendschneider and Robinson (1952), can be
eliminated by passing the samples through a cationic exchange resin,
Dowex 50W-X8, in the zinc form. This resin retains sulfide without
affecting nitrite and the technique can be applied to...
Most measures of program complexity gauge either textual or
control flow attributes of a program. A recent addition to the field
of complexity measures, the knot metric, is a function of both these
attributes. A knot measurement reflects the degree of control-flow
tangle in a program's listing. This thesis discusses...
Industrial expansion in a small city can have
a wide range of effects upon the immediate community and
surrounding labor force area. One example of this is the
impact that Tektronix, a worldwide electronics firm, could
have on the City of Lebanon, Oregon, where a plant, initially
employing about 500...
The major purpose of this exploratory study was to
develop an explanatory model of self-esteem and to interpret
the model using the Social Exchange framework. To
this end, a main effects and an interaction model emerged
which offer promise toward understanding the components of
self-esteem. This study examined 325 individual...
Concern regarding the lack of genetic variability and the apparent yield plateau reached in wheat breeding have prompted this investigation. The systematic crossing of spring and winter wheat types which have evolved to form somewhat different gene pools, may provide a source of additional usable genetic variability for future yield...
The purpose of this research was to evaluate the
effectiveness of two smoking cessation programs -- one
group and one self-help -- which were developed and are
currently employed by the American Cancer Society.
The research was conducted in a work setting, and
all subjects were employees of the State...
In 1976 and 1977 I examined three broad problems associated with the recruitment of young mallards, Anas platyrhynchos, in the Prairie Pothole Region of North Dakota. The three problems studied were: the effects of interspecific nest parasitism on production; the chronology and magnitude of total-brood loss during the brood-rearing period;...
