The purpose of this investigation was to develop a
valid and reliable instrument to assess Oregon high school
students' nutrition information.
The following steps were taken in order to achieve this
purpose.
First, a review of the literature pertaining to high
school nutrition curriculum was conducted.
Second, numerous published tests...
When stratification is employed to reduce the variance of an
estimate of the population mean, and the population does not possess an
a priori partitioning, the degree of reduction provided is affected by
the method of allocation, by the number of strata, and by the choice of
the stratum boundaries....
The present increasing need for the development of empirical hypotheses that explain the decisionmakers' behavior towards risk is to provide an understanding of the framework within which an industry operates. Such hypotheses could facilitate the implementation of policies designed to solve problems identified within an industry and could also provide...
This study investigated the effect of first aid instruction on
college students' attitudes toward safety. It evolved from previous
studies of the relationship between first aid and accidents in Canada
and the United Kingdom. These earlier studies were concerned with the
effect of first aid training on accident rates. The...
Three experiments were conducted on containerized seedlings to examine the short-term and long-term effects of environment on the root regeneration potential, and to examine the fate of the current photosynthate and its relationship to the root regeneration potential. The short-term effects were studied first in a 3x3x2 factorial experiment comprising...
Current meter moorings maintained over the Oregon continental shelf in 1973 and 1975 clearly show the difference between winter and spring oceanographic regimes and the rapid transition between the regimes. In winter the mean alongshore current is northward at all depths and strongest near shore; there is no mean vertical...
Three distinct stages of flower cluster abscission were identified
prior to fertilization: flowers which did not begin development (stage
1), flowers which had begun development (stage II) and clusters which
had begun to form distinct nuts (stage III). Abscission of stages I
and II coincided with a rapid increase in...
This report summarizes the 1979 ocean salmon fishing season off the Oregon coast. Troll fishery landings were obtained directly from commercial fish receiving tickets supplemented with a survey of fish buyers to obtain the most up-to-date estimate of total landings. Recreational catch and effort were obtained from creel census survey...
The development and evaluation of a system for the handling, maintenance
and transcription of nursing home patient care orders are
described.
Before implementation of this documentation system, the study
nursing home was found to be out of compliance with various state,
federal and professional practice standards related to patient care...
The North Atlantic zone of Costa Rica is an alluvial plain, whose fairly good soils and warm, extremely wet climate generate serious weed problems in cultivated crops and pastureland. Basic foods - corn, beans, rice and yuca - are important small farm crops. New land is still being opened for...
Meteorological aspects of geothermal energy development are first
discussed in general terms. An instructive case study is then presented
of a hypothetical 100 MW geothermal electrical generating plant at
a site near Vale, Oregon. Long-term climate data from Ontario Airport
near Ontario, Oregon, are used to describe meteorological characteristics
of...
Dietary fiber has been suggested as interfering with
mineral utilization. The influence of broccoli florets and
wastes, cauliflower heads and wastes, wheat bran and Metamucil
on mineral uptake by the rat was determined using
balance studies. All results were compared to control
animals fed diets containing 10% hydrolyzed cellulose.
Utilization...
Sediment transport measurements on Flynn Creek, a headwater stream in the Oregon Coast Range, have illustrated the magnitude of
fluvial transfer processes, primarily of the bedload component, during a moderate storm runoff season (1979 water year). The total dissolved solids concentration of storm runoff averaged 40 mg/L, and was independent...
The ethyl acetate extract of the culture filtrate of the marine Ascomycete,
Leptosphaeria oraemaris (Linder) yielded a novel metabolite
designated by the common name leptosphaerin. An x-ray crystallographic
structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)-
3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine
47 and D-mannitol 44. Oxidation of 47 followed...

The authors describe a consistent and theoretically sound methodology for evaluating nonmarket uses of forest resources, particularly those associated with recreation. The analytical methodology is applied to a forest management unit. Present net worth of developed campgrounds and dispersed recreation activities on Oregon State Department of Forestry Lands in 1977...
Even slight terrain inhomogeneities can cause large horizontal variations in the clear, stably stratified, nocturnal boundary layer largely through cold air drainage. By early morning the valleys and depressions can be several degrees cooler than the adjacent slopes and plateaus. As surface heating begins in the morning, these horizontal variations...
