This research addresses sample process variance estimation on continuous domains and for non-probability samples in particular. The motivation for the research is a scenario in which a program has collected non-probability samples for which there is interest in characterizing how much an extrapolation to the domain would vary given similarly...
This study explores the lived experiences of first-year, rural, Oregon students in their initial entry to college. Through qualitative research involving one-on-one interviews with 10 participants, the author examines the transition of rural students into higher education, common experiences of rural students in their first term of college, and perceived...
Helical anchors are a type of deep foundation element that can be installed quickly in almost any location and can accept the immediate application of operational loads. The use of helical anchors has expanded in recent decades from its established application in the power transmission industry to more traditional civil...
Wave dispersion and fracture are phenomena that involve. mechanisms triggered at the scale of a material's internal structure. Experiments were performed with a candidate material to judge the hypothesis that wave dispersion measurements can be used to nondestructively predict fracture strength. Wood-based particleboard was chosen as the candidate material because...
Maximal aerobic capacity (V̇O₂max) is the most widely used measure for assessing cardiorespiratory fitness. It is a strong contributor to performance in endurance sports, predicts functional capacity in older adults, and is related to overall disease risk. As such, it is important that testing methodologies for determining V̇O₂max provide valid...
Current public health guidelines for physical activity (PA) were primarily formulated using evidence collected from a series of prospective cohort epidemiological investigations that measured self-reported PA. In light of this observation, and the known discordance between self-reported and objectively-monitored PA, it remains common for researchers to assess compliance to current...
Shifting the Scholarly Conversation: A Rhetorical Reading of Peter Elbow's Work explores Peter Elbow's contributions to the field of writing and rhetoric. Over the course of his long career, Elbow’s scholarly and pedagogical work has been much praised and much criticized. Elbow's work has influenced generations of teachers and writers,...
The major purpose of this study was to determine if there were differences between well-trained pre- adolesents and untrained, but normally active counterparts in physical working capacity , body composition and blood lipids. The study hypotheses were that the trained subjects would have a lower mean body fat percentage, lower...
Thinning of young Douglas-fir forests has the potential to enhance structural diversity and improve habitat for wildlife. I examined the effects of thinning and thinning intensity on abundance and demographic characteristics of forest-floor small mammals in the Coast Range of Oregon 5 and 6 years after thinning had occurred. Thinning...
This dissertation examines tsunami and hurricane wave loads on bridge superstructures. Tsunamis have caused significant damage to coastal communities in recent years. For example, the 2011 Great East Japan Earthquake and resulting Tohoku Tsunami destroyed infrastructure along the east coast of Japan including bridge superstructures. Recent hurricanes have also caused...
