Investigation Into The Ratio Of Operating And Support Costs To Life-Cycle Costs For Dod Weapon Systems, Gary L. Jones, Edward D. White, Erin T. Ryan, Jonathan D. Ritschel

Faculty Publications

Recent legislation, such as the Weapon Systems Acquisition Reform Act of 2009, requires a renewed emphasis on understanding Operating and Support (O&S) costs. Conventional wisdom within the acquisition community suggests a 70:30 cost ratio with respect to O&S and acquisition of an average weapon system. Using 37 Air Force and Navy programs, the authors estimate the mean overall ratio of O&S costs to acquisition costs to be closer to 55:45, although many weapon systems displayed significant deviation from this 55 percent average. Contributing factors such as life expectancy and acquisition strategy (i.e., new system or modification) affect this variance. Their …

Developing The Law Of The River: The Integration Of Law And Policy Into Hydrologic And Socio-Economic Modeling Efforts In The Willamette River Basin, Adell Louise Amos

Publications

A legal and policy infrastructure -- referred to as a "law of the river" -- exists for every river basin in the U.S. an can be as important as natural processes in terms of managing the future of the resource. Because of the way that water law and policy have evolved in the U.S., this infrastructure involves a matrix of state and federal law that governs the choices that policymakers, end users, and agencies make. This "law of the river" provides the context in which decisions are made and not made. It also draws the boundaries within which decision makers …

The Potential Release Of Phosphorus In Floodplains, Maria S. Rossetti, Nicole K. Ownby, Erin Scott, Brian E. Haggard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

In the Illinois River Watershed, there has been growing concern over elevated phosphorus concentrations in the water column. This study evaluated how much phosphorus is contributed from floodplain soils into surface waters, examining the relationship between the flux of phosphorus released and the amount of phosphorus stored in the soil. This was investigated by artificially inundating soil cores from four sites and determining the soluble reactive phosphorus concentrations of the overlying water and the levels of Water and Mehlich-3 extractable phosphorus in the soil. The flux of phosphorus to the overlying water ranged from 0.43 to 6.61 mg m-2 hr-1 …

Methyl Coenzyme M Reductase (Mcra) Gene Abundance Correlates With Activity Measurements Of Methanogenic H2/Co2-Enriched Anaerobic Biomass, Rachel Morris, Anne Schauer-Gimenez, Ujwal H. Bhattad, Colleen Kearney, Craig Struble, Daniel Zitomer, James Maki

Civil and Environmental Engineering Faculty Research and Publications

Biologically produced methane (CH₄) from anaerobic digesters is a renewable alternative to fossil fuels, but digester failure can be a serious problem. Monitoring the microbial community within the digester could provide valuable information about process stability because this technology is dependent upon the metabolic processes of microorganisms. A healthy methanogenic community is critical for digester function and CH₄ production. Methanogens can be surveyed and monitored using genes and transcripts of mcrA, which encodes the α subunit of methyl coenzyme M reductase – the enzyme that catalyses the final step in methanogenesis. Using clone libraries and quantitative …

Timoshenko Beam Model For Lateral Vibration Of Liquid-Phase Microcantilever-Based Sensors, Joshua A. Schultz, Stephen M. Heinrich, Fabien Josse, Isabelle Dufour, Nicholas J. Nigro, Luke A. Beardslee, Oliver Brand

Civil and Environmental Engineering Faculty Research and Publications

Dynamic-mode microcantilever-based devices are potentially well suited to biological and chemical sensing applications. However, when these applications involve liquid-phase detection, fluid-induced dissipative forces can significantly impair device performance. Recent experimental and analytical research has shown that higher in-fluid quality factors (Q) are achieved by exciting microcantilevers in the lateral flexural mode. However, experimental results show that, for microcantilevers having larger width-to-length ratios, the behaviors predicted by current analytical models differ from measurements. To more accurately model microcantilever resonant behavior in viscous fluids and to improve understanding of lateral-mode sensor performance, a new analytical model is developed, incorporating both …

Lateral-Mode Vibration Of Microcantilever-Based Sensors In Viscous Fluids Using Timoshenko Beam Theory, Joshua Schultz, Stephen M. Heinrich, Fabien Josse, Isabelle Dufour, Nicholas J. Nigro, Luke A. Beardslee, Oliver Brand

Civil and Environmental Engineering Faculty Research and Publications

To more accurately model microcantilever resonant behavior in liquids and to improve lateral-mode sensor performance, a new model is developed to incorporate viscous fluid effects and Timoshenko beam effects (shear deformation, rotatory inertia). The model is motivated by studies showing that the most promising geometries for lateral-mode sensing are those for which Timoshenko effects are most pronounced. Analytical solutions for beam response due to harmonic tip force and electrothermal loadings are expressed in terms of total and bending displacements, which correspond to laser and piezoresistive readouts, respectively. The influence of shear deformation, rotatory inertia, fluid properties, and actuation/detection schemes on …

The Effects Of Explicit Listening Strategy Instruction On The Listening Comprehension Of English As Second Language (Esl) Community College Students, Yi Guan

Doctoral Dissertations

This mixed methods study explored the effects of explicit listening strategy instruction on the beginning-level ESL learner's listening comprehension at a community college in Northern California. Most previous studies measured the effectiveness of listening strategy instruction by comparing students' test scores, but little research explored the students' listening strategy development and their perceptions of the strategy instruction. Furthermore, no prior research exists on the effects of listening strategy instruction among community college students.

The researcher employed the concurrent triangulation approach, collecting and analyzing both quantitative and qualitative data simultaneously. Data sources included interviews, a listening test, background surveys, and classroom …

A Systemic Analysis Of The Defection Process In The Small Parcel Logistic Industry, Darrell J. Gualco

Doctoral Dissertations

The study of customer-initiated defection from one provider of services to another has been studied extensively in the business-to-consumer market. The reason to study defection patterns and analytics is to allow businesses to identify and control antecedents to defection that in turn will generate increased customer loyalty, market share, and profitability. Keaveney's study of defection was the starting point for understanding the key criteria individuals used to switch their purchasing criteria.

This research adds to existing defection theory by addressing the narratives of eight individuals who switched their vendor relationship in the small-parcel package industry. Prior to this research, no …

A Comparative Study Of Public Service Motivation Among Organizational Units In A Public University, Demerris Rochelle Brooks-Immel

Doctoral Dissertations

In the current economic climate of decreased utilitarian and extrinsic rewards, public higher education organizations are challenged to identify low-cost yet satisfying ways to motivate their employees. Previous researchers suggested that the motivation of public employees is a significant aspect of job satisfaction and job choice, attendance, retention, and performance, all of which impact organizational effectiveness. An understanding of what aspects of the organization, its values, and its mission are appealing to employees provides the organization with insight into how best to design work to be meaningful and rewarding; therefore, public-employee motivation should garner the attention of recruiters, managers, and …
