In public high schools, drug and alcohol prevention programs and policies have been ineffective in their deterrence of drug and alcohol use and abuse (Skager R., 2007). It is important to consider the needs of students and to create an effective, student centered drug and alcohol prevention program and policy....
Ammonia (NH₃) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching,
and nitrous oxide (NO₂). Enhanced efficiency N fertilizers...
The purpose of this study was to identify and examine risk and protective factors associated with residential instability within a sample of rural low-income mothers. Residential instability was defined as two or more residential moves within the course of a year. Qualitative and quantitative methods were used to compare residentially...
Agricultural revenues, the product of stochastic prices and yields, lead to markets which are
incomplete, thereby entreating and complicating economic inquiry. The following three essays
explore the incomplete nature of agricultural markets and consider the implications of
incompleteness for a range of policy questions and economic tools.
The first essay,...
Biohazardous waste refers to wastes that are potentially infectious to humans, as well as wastes from animal or plant research that could be potentially infectious to these organisms, or could alter their genetic selection process. Research resulting in generation of biohazardous waste is typically conducted at large, research-based universities. The...
Recent tsunami field surveys from the 2011 Great East Japan Earthquake and Tsunami have recorded numerous examples of tsunami-induced soil instability: significant scour around foundations, foundation failure of piles, and other damage caused by liquefaction. From the observations of soil instability leading to the failure of critical coastal structures, it...
Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...
Oxides of post-transition metals often show unique structures and properties due to the presence of lone pair electrons and the diffused s orbitals. The present work focuses on synthesis and characterizations of oxides containing Te, a heavy post transition metal.
New series of pyrochlore oxides of the formula Cs(M,Te)₂O₆ (M...
The issue of chloride-induced corrosion of reinforcing steel in concrete and its economic impacts are well-known. Chlorides that cause reinforcement corrosion can be from constituent materials used to prepare concrete or can enter the hardened concrete when the structure is exposed to chloride environments. To minimize the risk of reinforcement...
This thesis addresses the issue of comfortable and functional living environments to provide seniors with opportunities for "age in place," that is, living in one's own house after retirement. Such living environments enhance seniors' life satisfaction since the majority of seniors prefer to stay in their own houses and live...
