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

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 …

The Inevitable And Difficult Transition From Relation-Based To Rule-Based Governance In China, Shaomin Li

Management Faculty Publications

China has benefited tremendously from replying on the relation-based way of doing business and governance, as evidenced in its rapid economic growth up to now. However, further relying on the relation-based governance may eventually hinder China's economic growth and exacerbate inequality, resulting in political instability. On the other hand, given China's cultural heritage and powerful vested interest groups, can China shed its relation-based way? This article argues from logical, theoretical, and empirical perspectives the inevitability and difficulty of China's transition from relations to rules, and discuss the implications of the transition or the lack of it for China.

Appalachian And Pacific Crest Trail Hikers: A Comparison Of Benefits And Motivations, Eddie Hill, Edwin Gómez, Marni Goldenberg, Barbara Freidt, Stephanie Fellows, Laura Hill

Human Movement Studies & Special Education Faculty Publications

The Appalachian Trail (AT) and Pacific Crest Trail (PCT) are two scenic trails named in the National Trails System Act of 1968. Recently, trails and footpaths have been used to promote such benefits as healthy lifestyles, sense of community, and an increased quality of life. The purpose of this study was to compare the motivations and benefits from hikers of the AT and the PCT. Grounded in Driver’s benefits model and means-end theory, and using an Internet questionnaire, 766 usable questionnaires were collected. Significant differences were found between AT and PCT users who: hike to prevent a worse health condition; …

A Qualitative Assessment Of Virginia Beach Dog Park Users, Edwin Gómez, John Hunting

Human Movement Studies & Special Education Faculty Publications

The purpose of this paper is to look at a Virginia Beach, Virginia (VA) dog park as a case study exploring the benefits and perceptions of dog parks by its users. The qualitative methodology follows an earlier dog park study by Gómez (2013) in Norfolk, VA. Our findings indicated three major themes: (a) dog exercise, (b) socialization for dogs (and humans), and (c) safe off-leash place. Findings from Virginia Beach are compared to earlier findings in Norfolk.

Information Architecture For Social Media: A Case Study On Building An Event Backchannel With Twitter, Robert L. Moore

STEMPS Faculty Publications

This paper presents a case study on creating a backchannel through Twitter for the live event, featuring the Secretary of the US Navy, hosted by the School of Government. The project, which ultimately was successful in creating social media buzz for the lecture, was a new approach for the School of Government in how it markets its events. The study discusses the tools and processes used in the backchannel's creation and development. This paper was written because the author discovered a gap in existing literature on creating backchannels. It outlines how the adaptation of best practices from the general population's …

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 …

Toward A Formalism Of Modeling And Simulation Using Model Theory, Saikou Y. Diallo, Jose Padilla, Ross Gore, Heber Herencia-Zapana, Andreas Tolk

VMASC Publications

This article proposes a Modeling and Simulation (M&S) formalism using Model Theory. The article departs from the premise that M&S is the science that studies the nature of truth using models and simulations. Truth in models and simulations is relative as they seek to answer specific modeling questions. Consequently, truth in M&S is relative because every model is a purposeful abstraction of reality. We use Model Theory to express the proposed formalism because it is built from the premise that truth is relative. The proposed formalism allows us to: (1) deduce formal definitions and explanations of areas of study in …

A Hybridized Approach To Validation: The Role Of Sociological Research Methods In Pedestrian Modeling, Erika Frydenlund, Terra Elzie, Andrew Collins, R. Michael Robinson

VMASC Publications

Pedestrian and crowd-movement models are difficult to validate using traditional empirical methods because of data-related issues such as generalizability, collection ethics, and costs. Commonly used validation methods make strong assumptions about emergence and the importance of crowd structure, leaving a gap in validation literature. The paper reviews the most common methods of validating pedestrian models and proposes a hybridized qualitative approach to validating models that covers more complex group dynamics and possible situations of panic.

Do Groups Matter? An Agent-Based Modeling Approach To Pedestrian Egress, Andrew Collins, Terra Elzie, Erika Frydenlund, R. Michael Robinson

VMASC Publications

Festivals in city parks attended by individuals and families are a universal feature of urban life. These venues often have the common attributes of vendors and other obstacles that restrict pedestrian movement through certain areas, as well as fixed number of exits. In this study, the authors build an agent-based model (ABM) that incorporates group cohesion forces into this type of pedestrian egress scenario. The scenario considered was an evacuation of 500 people through a single exit. This allowed an investigation into the use of two different simulated pedestrian's heading updating rules.

Perceptions Of The Counseling Profession: From Health Science Graduate Faculty And Students, Kaprea F. Johnson, Christianne Fowler, Karen Kott, Margaret Lemaster

Ellmer School of 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.

Voices At The Table: Collaboration And Intertextuality, Sue C. Kimmel, Kathryn Kennedy (Ed.), Lucy Santos Green (Ed.)

STEMPS Faculty Publications

While we often associate reading aloud with children and particularly younger children, the practice of reading aloud has historically been a way for a community to share texts for information and enjoyment. Findings from a year-long study of a school librarian collaborating with a team of second grade teachers demonstrates the value of reading aloud in building background knowledge and vocabulary, modeling, understanding curriculum, creating common texts, and reading for enjoyment. Reading aloud brought other voices to the table in a clear example of intertextuality. Implications are shared for school librarians interested in similar practices as well as future research …

Direct Stratospheric Injection Of Biomass Burning Emissions: A Case Study Of The 2009 Australian Bushfires Using The Nasa Giss Modele2 Composition-Climate Model, Robert Field, Mike From, Apostolos Voulgarakis, Drew Shindell, Mike Flannigan, Peter Bernath

Chemistry & Biochemistry Faculty Publications

Direct stratospheric injection (DSI) of forest fire smoke represents a direct biogeochemical link between the land surface and stratosphere. DSI events occur regularly in the northern and southern extratropics, and have been observed across a wide range of measurements, but their fate and effects are not well understood.

DSIs result from explosive, short-lived fires, and their plumes stand out from the background concentrations immediately. This makes it easier to associate detected DSIs to individual fires and their estimated emissions. Because the emissions pulses are brief, chemical decay can be more clearly assessed, and because the emissions pulses are so large, …

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 …

Eat It: Sex, Food And Women's Writing [Book Review], Marc Ouellette

English Faculty Publications

Simply put, Eat It: Sex, Food and Women's Writing surpasses its rather immodest claims. This is no mean feat, for the editors allow that they have collected short stories, nonfiction shorts and poetry that, as the back claims offers, hinge "on the carnal." More than that, the gathered works purportedly address the ways in which experiencing food entails nothing short of "power, biology, social obligation, experimentation, nourishment, pain and pleasure." The authors treat the topics, ranging from the politics of potatoes to tricks for field dressing deer, with a blend of seriousness and humour befitting the material. What becomes clear …

Intermediate Inputs And External Economies, Haiwen Zhou

Economics Faculty Publications

Is the degree of external economies (at the industry level) higher than the degree of internal increasing returns (at the firm level)? If so, what is the exact source of this difference? In the general equilibrium model in which firms producing final goods choose the degree of specialization of their technologies, external economies arise from the usage of intermediate inputs and the existence of internal increasing returns. It is frequently assumed that increasing returns are absent at the firm level while present at the industry level. In this model, the existence of increasing returns at the firm level is necessary …

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.

Gendered Violence: Continuities And Transformation In The Aftermath Of Conflict In Africa, Pumla Gobodo-Madikizela, Jennifer Fish, Tamara Shefer

Women's & Gender Studies Faculty Publications

This thematic cluster of essays, titled “Gendered Violence: Continuities and Transformation in the Aftermath of Conflict in Africa,” focuses on the continuities between regimes of violence during organized political conflict and persisting violence against women in the postconflict era of democratic governance. The genesis for this collection evolved out of an international symposium organized by the first author of this introduction, in August 2011. The aim of the symposium was to explore African women’s experiences in the aftermath of mass violence and genocide—both in terms of their victimhood and their agency—and their positioning in the broader context of their social, …

This research investigates the relative effects of lower-order and higher-order aspects of quality of work life (QWL) on employee job satisfaction and overall life satisfaction in Thai workplaces. The data were collected by means of questionnaires mailed to employees of 6 selected companies-3 companies in each of the service and manufacturing sectors in Thailand with respective response rates of 72 and 74 percent. The results reveal that the two aspects of QWL in all companies have a positive impact on both aspects of employee satisfaction: job satisfaction and overall life satisfaction. The results also reveal a generally more important role …

What Constitutes The Success Or Failure Of Multinational Corporations (Mncs) In Foreign Markets? A Case Study Of Chinese And American Mncs, Shiwei Jiang

Graduate Program in International Studies Theses & Dissertations

Scholars have identified multinational corporations (MNCs) as increasingly important and influential actors in international politics. However, mainstream international studies scholarship has failed to explain why MNCs succeed or fail in entering foreign markets. Market entry is a particularly vexing question for U.S. and Chinese firms seeking to compete for each other's consumers. As this study shows, surprising differences in success among U.S. firms in China, as well as Chinese firms in the U.S., suggest that statist and market factors interact with corporate strategies in confounding ways. Through case studies in the internet, automobile and fast food industries, this dissertation builds …

Nuclear Security Complexes: An Alternative Approach To Nuclear Nonproliferation, Beyza Unal

Graduate Program in International Studies Theses & Dissertations

Existing literature examines nuclear proliferation from a regional or a national perspective but nuclear issues are inherently transnational. The literature also often focuses on single-state policies for deterrence purposes. Following tailored (single-state) policies, however, is too narrow because these policies are bilateral and based on national interest; they do not include global concerns. In response to the literature, this dissertation proposes to examine states grouped according to their state characteristics in terms of threat existence, democracy level in the nuclear field, and membership in nuclear organizations and compliance with major nuclear treaties. The focus here is to ask: "Does regional …

Physician As Teacher: Promoting Health And Wellness Among Elementary School Students, Jill E. Stefaniak, Victoria C. Lucia

STEMPS Faculty Publications

BACKGROUND: Every day, physicians engage in teaching during their patient encounters. It may be that medical students who are introduced to the principles of teaching and learning are more likely to become good communicators and learners. Service-learning may be an effective way for medical students to practice skills in teaching and communication in a real-world setting, while also filling a need within the community. The purpose of this study was to identify common themes within medical students' reflections on what they learned through participating in a teaching exercise with local elementary school children.

Do Non-Citizens Vote In U.S. Elections?, Jesse T. Richman, Guishan A. Chattha, David C. Earnest

Political Science & Geography Faculty Publications

In spite of substantial public controversy, very little reliable data exists concerning the frequency with which non-citizen immigrants participate in United States elections. Although such participation is a violation of election laws in most parts of the United States, enforcement depends principally on disclosure of citizenship status at the time of voter registration. This study examines participation rates by non-citizens using a nationally representative sample that includes non-citizen immigrants. We find that some non-citizens participate in U.S. elections, and that this participation has been large enough to change meaningful election outcomes including Electoral College votes, and Congressional elections. Non-citizen votes …

Facebook And Dramauthentic Identity: A Post-Goffmanian Model Of Identity Performance On Sns, Dylan E. Wittkower

Philosophy Faculty Publications

Early and persistent scholarly concerns with online identity emphasized the ways that computer–mediated communications have allowed new, inventive, and creative presentations of self, and the lack of connection between online identity and the facts of off–line life. After the ascendency and following ubiquity of Facebook, we find our online lives transformed. We have not only seen online identity reconnected to off–line life, but we have seen, through the particular structures of social networking sites, our online lives subjected to newfound pressures to unify self–presentations from various constitutive communities; pressures different from and in some ways greater than those of off–line …
