Methane derived authigenic carbonate (MDAC) precipitation occurs within marine sediments as a byproduct of the microbial anaerobic oxidation of methane (AOM). While these carbonates form in chemical and isotopic equilibrium with the fluids from which they precipitate, burial diagenesis and recrystallization can overprint these signals. Plane polarized light (PPL) and...
Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....
Purpose of the Study The purpose of the study was to determine if differences existed in commitment to teacher collective bargaining associations among vocational teachers. The objectives were: (1) to determine the degree of commitment among secondary vocational teachers to the teachers' collective bargaining association; and (2) to determine the...
The natural environment provides important services and benefits to peoples’ health and lives. Conversely, environmental disservices can have negative impacts on humans such as through pollution, chemical toxins, and climate change. The combination of environmental services and disservices encompass how human health and wellbeing, and the environment are connected. As...
Currently the production of biofuel from algae is not economically competitive with petroleum fuel. However, co-production of high-value products may be able to justify the cost of large-scale algae cultivation. The basic goal of this study is to develop a techno-economic analysis (TEA) and Life-cycle assessment (LCA) for the production...
For coaches to qualitatively analyze the performance of sport skills as executed by their
students, they must possess an internal image of the desired skill against which to make
comparisons (Hoffman, 1983; Pinheiro & Simon, 1992). Leas and Chi (1993) have
indicated that there are differences between novice and expert...
Douglas-fir (Psudotsuga menziesii (Mirb.) Franco) seedlings were outplanted on eight dates (every three weeks from mid-August 2005 through mid-January 2006). On each plant date, seedlings from a conventional dormancy (CONV) induction treatment, including moisture and nutrient stress, and a shortened daylength (SD) treatment were outplanted on three western Oregon sites...
Marine environments provide services for ecosystems and humans, but face many threats, including sea star wasting disease (SSWD) and ocean acidification (OA). Biological research on these threats is abundant, but there has been limited research examining the human dimensions of these threats. This thesis contains two standalone articles that explore...
