Wheat is the primary field crop in Oregon. Selection of time of sale is one of the most important marketing problems facing grain producers. The objectives of the study deal with economic considerations involved in a wheat producer's marketing process including factors motivating the time of sale, price analysis, availability...
This study examined the experience of three secondary
science student teachers from Western Oregon State College
in Monmouth, Oregon during the Spring quarter of 1990. The
question was: What is student teaching like from the point
of view of the student teacher?
The research methodology was qualitative, more
specifically participant...
The characteristics and interactions of the riparian
stand, large woody debris (LWD), and channel morphology
were examined on five undisturbed, low gradient streams in
southeast Alaska. One first-, two second-, one third-,
and one fourth-order streams were studied. Stream
morphology variables were measured systematically at fixed
intervals of three to...
Several types of channel morphology measurement parameters used to
characterize fish habitat of small streams are refined, developed and evaluated in terms
of their accuracy, precision, and sensitivity to disturbance. Data for 74 stream reaches
in Oregon and Alaska are used in analysis. Over half the reaches are from a...
Hop looper, Hypena humuli Harris, can cause substantial defoliation and crop damage by feeding on hop leaves and cones. A 4-yr field study conducted in western Oregon evaluated the abundance of hop looper larvae and associated defoliation of leaves on plants fertilized with nitrogen rates ranging from 44.8 to 269...
This paper analyses the factors explaining productivity and efficiency differences across salmon aquaculture farms, with an emphasis on agglomeration externalities. We specify a stochastic frontier production model with agglomeration indexes included in both the frontier production function and the technical inefficiency model. The frontier model is estimated on a rich...
