School of Public Service Faculty Publications
This research examines citizen acceptance of tolls and road pricing, and specifically focuses on determinants of the individual’s expressed willingness-to-pay tolls to use a tunnel express lane that would be free of traffic delays. We answer the research question “What factors influence citizens’ willingness-to-pay tolls” by empirically estimating a four factor model of willingness-to-pay: (a) direct benefit to the respondent; (b) relative cost over time; (c) community concern; and (d) political and environmental liberalism. We use data about citizen perceptions from the Life in Hampton Roads Survey, a survey of residents of Hampton Roads, Virginia. We find that willingness-to-pay is …
Agent-Based Simulation Of Mass Shootings: Determining How To Limit The Scale Of A Tragedy, Roy Hayes, Reginald Hayes
Agent-Based Simulation Of Mass Shootings: Determining How To Limit The Scale Of A Tragedy, Roy Hayes, Reginald Hayes
VMASC Publications
An agent-based simulation was created to examine key parameters in mass shootings. The goal of the simulation was to examine the potential effectiveness of Senator Dianne Feinstein's (D-Calif.) assault weapons and high-capacity magazines bill. Based on the analysis, the proposed law would have a negligible effect on the number of people shot during mass shootings. The assault weapons portion of the proposed bill will have no effect on the number of people killed or wounded in a mass shooting. The assault weapons ban does not seek to decrease the rate of fire of any firearm. Of the parameters tested a …
Outsourcing Expert Services By State Transportation Departments: A Look At Effects On Cost, Quality, And Changing Employment Levels, Juita-Elena Yusuf, Lenahan O'Connell
Outsourcing Expert Services By State Transportation Departments: A Look At Effects On Cost, Quality, And Changing Employment Levels, Juita-Elena Yusuf, Lenahan O'Connell
School of Public Service Faculty Publications
Privatization has increasingly become a policy option for government agencies struggling to meet rising demands for services but with fewer resources. In the transportation arena, many state departments of transportation (DOTs) have privatized by outsourcing highway functions to the private sector. But the outsourcing of technical and expert services such as those related to the design and construction of highway infrastructure may result in a smaller or less knowledgeable DOT workforce that is unable to perform the necessary contract management to ensure the quality of the work done by contractors. We posit an outsourcing process in which DOTs respond to …
Modelling Follow Up Time At A Single-Lane Roundabout, Xiaobo Qu, Jin Zhang, Shuaian Wang, Zhiyuan Liu
Modelling Follow Up Time At A Single-Lane Roundabout, Xiaobo Qu, Jin Zhang, Shuaian Wang, Zhiyuan Liu
School of Public Service Faculty Publications
The follow up time is an important parameter for estimating the entry capacity of roundabouts. However, its variability and contributing factors have long been ignored in the literatures. In this study, 171 follow up samples and contributing factors (traffic volume, vehicle position, waiting vehicles behind, vehicle type, and drivers’ gender) are collected at a roundabout in Pacific Pines, Australia. It is found that the follow up time is indeed significantly affected by traffic volume, waiting vehicles behind, vehicle type, and drivers’ gender. In order to establish the relationship between the follow up time and its contributing factors, an inverse Gaussian …

Evaluating Spatial Model Accuracy In Mass Real Estate Appraisal: A Comparison Of Geographically Weighted Regression And The Spatial Lag Model, Paul E. Bidanset, John R. Lombard
Evaluating Spatial Model Accuracy In Mass Real Estate Appraisal: A Comparison Of Geographically Weighted Regression And The Spatial Lag Model, Paul E. Bidanset, John R. Lombard
School of Public Service Faculty Publications
Geographically weighted regression (GWR) has been shown to greatly increase the performance of ordinary least squares-based appraisal models, specifically regarding industry standard measurements of equity, namely the price-related differential and the coefficient of dispersion (COD; Borst and McCluskey, 2008; Lockwood and Rossini, 2011; McCluskey et al., 2013; Moore, 2009; Moore and Myers, 2010). Additional spatial regression models, such as spatial lag models (SLMs), have shown to improve multiple regression real estate models that suffer from spatial heterogeneity (Wilhelmsson, 2002). This research is performed using arms-length residential sales from 2010 to 2012 in Norfolk, Virginia, and compares the performance of GWR …
Generic Incident Model For Investigating Traffic Incident Impacts On Evacuation Times In Large-Scale Emergencies, Andrew J. Collins, Peter Foytik, Erika Frydenlund, R. Michael Robinson, Craig A. Jordan
Generic Incident Model For Investigating Traffic Incident Impacts On Evacuation Times In Large-Scale Emergencies, Andrew J. Collins, Peter Foytik, Erika Frydenlund, R. Michael Robinson, Craig A. Jordan
VMASC Publications
Traffic incidents cause a ripple effect of reduced travel speeds, lane changes, and the pursuit of alternative routes that results in gridlock on the immediately affected and surrounding roadways. The disruptions caused by the secondary effects significantly degrade travel time reliability, which is of great concern to the emergency planners who manage evacuations. Outcomes forecast by a generic incident model embedded in a microscopic evacuation simulation, the Real-Time Evacuation Planning Model (RtePM), were examined to quantify the change in time required for an emergency evacuation that results from traffic incidents. The incident model considered vehicle miles traveled on each individual …
The Role Of Politics And Proximity In Sea Level Rise Policy Salience: A Study Of Virginia Legislators’ Perceptions, Juita-Elena (Wie) Yusuf, Burton St. John Iii, Ivan K. Ash

The acceleration of sea level rise (SLR) has become a threat to the stability of nation-states worldwide and associated with risks to environmental sustainability, economic infrastructure, and public health. However, from both an international and U.S. perspective, there is a lack of research examining legislative decision makers’ perceptions about policies regarding SLR. This study addresses that gap by examining how politics and proximity affects Virginia state legislators’ perceptions of the saliency of SLR. A survey of these legislators reveals their perceptions of credible sources of information, SLR-related risk, and who should take the lead to address SLR. While this study …

Perceptions Of The Counseling Profession: From Health Science Graduate Faculty And Students, Kaprea F. Johnson, Christianne Fowler, Karen Kott, Margaret Lemaster
Perceptions Of The Counseling Profession: From Health Science Graduate Faculty And Students, Kaprea F. Johnson, Christianne Fowler, Karen Kott, Margaret Lemaster
Nursing Faculty Publications
Counseling is considered a newer healthcare profession and possibly unknown to others. This study uses a post-positivist phenomenological approach exploring healthcare faculty and students' perceptions of counseling professionals after participating in a semester long interprofessional health promotions and maintenance course. Results indicated most professions are unaware of counselors, their scope of practice, and their benefit to interprofessional teams. Participants showed growth in their knowledge. Results indicate the importance of interprofessional education and need for advocacy awareness.
International Trade With Increasing Returns In The Transportation Sector, Haiwen Zhou
International Trade With Increasing Returns In The Transportation Sector, Haiwen Zhou
Economics Faculty Publications
In this general equilibrium framework, the transportation sector is modeled as a distinct sector with increasing returns. A more advanced technology has a higher fixed cost but a lower marginal cost of production. Even with both manufacturing firms and transportation firms engaged in oligopolistic competition and optimally choosing their technologies, the model is tractable and results are derived analytically. Technology adoptions in the manufacturing sector and transportation sector are reinforcing, and multiple equilibria may exist. Firms choose more advanced technologies and the prices decrease when the size of the population is larger.
High-Intensity Tasks With External Load In Military Applications: A Review, Eric K. O'Neal, Jared H. Hornsby, Kyle J. Kelleran
High-Intensity Tasks With External Load In Military Applications: A Review, Eric K. O'Neal, Jared H. Hornsby, Kyle J. Kelleran
Human Movement Sciences & Special Education Faculty Publications
This article provides a synopsis of the limited investigations examining the impact of external load (EL) on performance of high-intensity tasks under load (HITL), EL training intervention effects on HITL performance, and injuries from EL training. Repetitive lifting tasks and initiation of locomotion, such as rapidly moving from a prone position to sprinting appear to be more hindered by EL than maximal sprinting velocity and may explain why training with EL does not improve obstacle course or prolonged (200-300 yard shuttle) drills. EL training appears to offer very little if any benefit for HITL in lesser trained populations. This contrast …

Most of the studies to explore the impact of distracted driving have been descriptive in nature; i.e. the research is conducted in naturalistic settings to evaluate the performance of the driver with and without distracters. However simulation models can also be used that predict the workload for driving tasks. Using concepts from process modeling, baseline models of driving tasks can be created for different driving sequences that include the associated fine motor, visual and cognitive human resources. These models can then be used to evaluate incidents of workload overload caused by different distracters, from both the internal and external vehicle …
Educational Policy Decisions Effect Upon Same-Gender Public Education, Richard Gerard Catoire
Educational Policy Decisions Effect Upon Same-Gender Public Education, Richard Gerard Catoire
Educational Leadership & Workforce Development Theses & Dissertations
The No Child Left Behind (NCLB) Act of 2001, with emphasis on greater choice and flexibility for parents and students in public education, to include the provision for same-gender public schools and classrooms, led to a resurgence in same-gender public education in the United States. With the results of the research on same-gender education presenting conflicting evidence and mixed-perspectives on the outcomes of same-gender education in improving academic achievement or attainment, there are still questions to be answered, not only to the effectiveness of same-gender education, but also to policy decisions to establish same-gender public education programs. While proponents of …
Community College Students With Psychological Disorders And Their Perceptions Of Online Learning, Gretchen Winifred Langford Warren
Community College Students With Psychological Disorders And Their Perceptions Of Online Learning, Gretchen Winifred Langford Warren
Educational Leadership & Workforce Development Theses & Dissertations
Research focusing on students with learning disabilities is abundant for secondary and higher education. Studies utilizing data on students with psychological disorders cover secondary and 4-year university education. However, community college students with psychological disorders and their perception of online classes is an area of educational research which lacks data. Students across a wide spectrum of psychological disorders tend to find learning challenging. The community college's learning environment may best fit their learning styles. With modem educational innovations, the online learning methods must take into consideration the unique psychosocial, cognitive, and academic needs of the community college student population.
