Mixed-Mode Surveys: A Strategy To Reduce Costs And Enhance Response Rates, Daniel Tobin, Joan Thomson, Rama Radhakrishna, Luke Laborde Dec 2012

Mixed-Mode Surveys: A Strategy To Reduce Costs And Enhance Response Rates, Daniel Tobin, Joan Thomson, Rama Radhakrishna, Luke Laborde

Journal of Extension

Mixed-mode surveys present one opportunity for Extension to determine program outcomes at lower costs. In order to conduct a follow-up evaluation, we implemented a mixed-mode survey that relied on communication using the Web, postal mailings, and telephone calls. Using multiple modes conserved costs by reducing the number of postal mailings yet maintained an acceptable response rate (67.1%). The case presented here provides further evidence that using mixed-mode survey techniques provides Extension with a tool to conduct rigorous survey research while adapting to budget constraints.

An Affordance-Based Framework For Human Computation And Human-Computer Collaboration, R. Jordan Crouser, Remco Chang

Computer Science: Faculty Publications

Visual Analytics is “the science of analytical reasoning facilitated by visual interactive interfaces” [70]. The goal of this field is to develop tools and methodologies for approaching problems whose size and complexity render them intractable without the close coupling of both human and machine analysis. Researchers have explored this coupling in many venues: VAST, Vis, InfoVis, CHI, KDD, IUI, and more. While there have been myriad promising examples of human-computer collaboration, there exists no common language for comparing systems or describing the benefits afforded by designing for such collaboration. We argue that this area would benefit significantly from consensus about …

Computer Science: Faculty Publications

While there is currently significant interest in developing Unmanned Aerial Systems (UASs) that can be supervised by a single operator, the majority of these systems focus on Intelligence, Surveillance, and Reconnaissance (ISR) domains. One domain that has received significantly less attention is the use of multiple UASs to insert or extract supplies or people. To this end, MAVIES (Multi-Autonomous Vehicle Insertion-Extraction System) was developed to allow a single operator the ability to supervise a primary cargo Unmanned Aerial Vehicle (UAV) along with multiple scouting UAVs. This paper will detail the development of the design requirements generated through a Hybrid Cognitive …


Optimization Of Nonlinear Switch Cells For Switching Converters, Bradley Alan Reese Dec 2012

Optimization Of Nonlinear Switch Cells For Switching Converters, Bradley Alan Reese

Graduate Theses and Dissertations

Switch cells consist of an array of power switches and passive components which can replace the main switches alone in many power topologies, allowing reduced switching loss without altering the power topology directly. This thesis discusses the development of a switch cell topology that utilizes a saturable resonant inductor to reduce the size and power loss of the cell. Additionally, the cell transfers energy stored in the inductor into a capacitor for efficient energy storage during the cell's conduction region. This energy is then transferred back to the system when the cell turns off, thus reducing the total switching energy.

Journal of Educational and Psychological Studies

This study examined the association between type A behavior, emotional intelligence, social self-efficacy, and work motivation among faculty members at the Hashemite University in Jordan. Seventy seven faculty members responded to four measures: Type A behavior scale, emotional intelligence scale, perceived social self-efficacy scale, and work motivation scale. The results of this study revealed that emotional intelligence was positively and significantly related to work motivation. Moreover, this study confirmed the value of emotional intelligence as a significant predictor of work motivation. However, social-self-efficacy and Type A behavior proved to be non significant predictors of work motivation


Use Of Pile Driving Analysis For Assessment Of Axial Load Capacity Of Piles, Rodrigo Salgado, Yanbei Zhang Dec 2012

Use Of Pile Driving Analysis For Assessment Of Axial Load Capacity Of Piles, Rodrigo Salgado, Yanbei Zhang

JTRP Technical Reports

Driven piles are commonly used in foundation engineering. Pile driving formulae, which directly relate the pile set per blow to the capacity of the pile, are commonly used to decide whether an installed pile will have the designed capacity. However, existing formulae have been proposed based on empirical observations and have not been validated scientifically, so some might over-predict pile capacity, while others may be too conservative. In this report, a more advanced and realistic model developed at Purdue University for dynamic pile driving analysis was used to develop more accurate pile driving formulae. These formulae are derived for piles …

Sediment Based Turbidity And Bacteria Reduction Analysis In Simulated Construction Site Runoff, James W. Berry Iii Dec 2012

Sediment Based Turbidity And Bacteria Reduction Analysis In Simulated Construction Site Runoff, James W. Berry Iii

All Theses

Large construction projects are highly vulnerable to sediment removal by erosive forces. Turbidity, resulting from this excess sediment, has gained recognition as anindicator of pollution in surface runoff from construction activities. The Environmental Protection Agency (EPA) is currently moving toward regulations that would establish a nationwide maximum turbidity effluent limit discharged from construction sites. Research has shown that current sediment control best management practices (BMPs) are often ineffective at controlling elevated turbidity levels in construction site discharges. Additionally, research confirms that sediment basins may act as reservoirs for bacteria, specifically Escherichia coli (E. coli). During rainfall events, resuspension within sediment …

Estimating Water Flux And Storage Using Displacement Measurements In Saprolite At Depth, Clay Freeman Dec 2012

Estimating Water Flux And Storage Using Displacement Measurements In Saprolite At Depth, Clay Freeman

All Theses

Water storage in the soil is important for many hydrologic problems, but measuring how the storage changes at an appropriate scale remains a challenge. The objective of this thesis is to evaluate the feasibility of estimating change in water content in soil by measuring vertical displacement in underlying soils. This approach is appealing because the averaging volume of the displacement scales with the depth at which the measurements are taken. This should result in measurements of changes in soil moisture that are averaged over regions 10s to 100s of meters across, a measurement scale that is much larger than that …
