Nonparametric model-assisted estimators have been proposed to improve estimates of finite population parameters. More efficient estimators are obtained when the parametric model is misspecified due to the flexibility of nonparametric models. In this dissertation, we derive information criteria to select appropriate auxiliary variables to use in an additive model-assisted method....
While grammar is a core aspect of written and oral communication, many find grammar instruction equally frustrating and boring, and as such, grammar receives very little formal attention in the university system (Hoffman). My thesis draws attention to this overlooked, and yet central component of composition, and asks a radical...
My thesis examines a total of fourteen characters from The Portrait of a Lady and The Turn of the Screw. Primarily, I have discovered an overwhelming pattern in these two works by Henry James; when characters make direct entrances--that is when they are not described or discussed in absentia by...
The debate over a coastal migration route for the First Americans revolves around two major points: seafaring technology, and a viable landscape and resource base. Three lake cores from Sanak Island in the western Gulf of Alaska yield the first radiocarbon ages from the continental shelf of the Northeast Pacific...
Research indicates that child sex abuse contributes to emotional and behavioral
dysfunction in adult survivors. However, no one factor within the abuse experience has
been found to independently affect adult functioning, and it is unclear if several factors
acting together influence degree of dysfunction. This study compared the Global
Assessment...
This qualitative study investigated the sibling relationship as it was described through the voices of the children. Ten sibling dyads (brother-sister or brother-brother) involved in family treatment following the discovery of sibling incest were interviewed. Participants in this study were participants in an outpatient clinic in the Northwest during the...
Successful software systems evolve over their lifetimes through the cumulative changes made by software maintainers. As software evolves, the problems resulting from software change worsen, exacerbated by increased system size and complexity, lack of program understanding, amount of effort required to make changes, and number of personnel involved. Experience shows...
The purpose of this project was to create a code generating software tool, which is one section of the Oregon SpeedCode Universe. The Code Generator automatically generates compilable source code to form working Macintosh applications. This source code provides a prototype for the actual final application. This is done with...
Oregon's land use planning program to preserve
the agricultural land base and to maintain the agricultural
economy is dependent on detailed information concerning the
structure of commercial agricultural enterprises. This
information is presently incomplete and it was the purpose of
this research to test a systematic technique for collecting it....
This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...
