Simultaneous Equation Modeling For Crash Rate Of Freeway Segments, Anthony Ramos

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 2010, the total number of reported traffic crashes in the state of Nevada was 51,664 of which 235 (0.6%) resulted in one or more deaths (Nevada Department of Transportation, 2012). The state's "Zero Fatalities" traffic safety campaign aims to reduce the rate even further. Out of the total number of crashes, Clark County (includes Las Vegas) accounted for 78.89%. This study examines safety improvement by developing advanced crash prediction models. The system of crash prediction equations consider geometric conditions and traffic volume using simultaneous equation modeling (SEM). The models are based on geometric characteristics and traffic volume data collected …

Highway Routine Maintenance Cost Estimation For Nevada, Monika Hagood

UNLV Theses, Dissertations, Professional Papers, and Capstones

State highway agencies are obligated to maintain existing roads for the highway systems to work efficiently and with greater longevity. Every year NDOT is responsible for approximately 13,150 lane miles of existing infrastructure. With that in mind, resources need to be provided to maintain the highway system.

The purpose of this research was to estimate annual routine maintenance cost for several typical treatment methods of highways. Five prioritization categories of highways used by NDOT were considered. Linear regression models were developed that present the relationship between costs including total maintenance cost and five maintenance cost components: labor, equipment, materials, manpower …

The exploratory study should be useful to lawmakers and business leaders in shaping Nevada’s future. It could provide essential information focusing on whether Las Vegas should actively pursue an online gaming cluster.

Observability In Traffic Modeling: Eulerian And Lagrangian Coordinates, Sergio Contreras

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traditionally, one of the ways traffic flow has been studied is by using the kinematic wave model. This model is studied in the Eulerian framework. Recently, the kinematic wave model has been transformed into Lagrangian coordinates. This model of traffic flow together with the concept of observability for linear time invariant discrete time systems is applied to study the observability of four sections of a freeway in both Eulerian and Lagrangian coordinates. A system with densities in four sections of a freeway is designed, and the observability of the system is studied with different situations for sensors. When the system …

This study utilized data from the Southern Nevada Strong ethnographic research project. Ethnographic research was conducted over ten weeks in Summer 2013. Neighborhood observations and interviews with community stakeholders were conducted to understand how neighborhoods are utilized, how residents feel about potential redevelopment, and what areas of the neighborhoods residents would like to see improved in the future. Photographs were also collected to further examine the characteristics, aesthetics, and spatial landscape of the neighborhoods. The purpose of this qualitative research project …

Adapting An American Non-Profit Model To An International For-Profit Model: A Case Study Of Clean The World Business Model In Hong Kong, Yun Guan

UNLV Theses, Dissertations, Professional Papers, and Capstones

The non-profit sector in the United States had grown at a fast pace in the recent decades, partially as a result of the economic development and the influence of social and political factors. By pursuing mission rather other bottom line, nonprofit organizations faced fierce competition for government grants and private donations. Limited financial resources constrained their efforts to create social and environmental value. The emerging hybrid nonprofit business model offered a new approach for nonprofits to pursuing self-sustainable development both domestically and internationally. However, adapting a unique American nonprofit model into an international for-profit model could be challenging because of …

Walt Disney And The Propaganda Complex: Government Funded Animation And Hollywood Complicity During Wwii, Amanda Cunningham

Graduate Research Symposium (2010 - 2017)

Walt Disney’s work as an animator during World War II had a measurable impact on culture and in the development of government produced messages. It is important to examine this understudied area of Disney’s life and his studio’s efforts to produce wartime training and propaganda films during WWII. Government agencies, including the U.S. Treasury, contracted Disney to produce 32 animated shorts between 1941 and 1945 (Gabler, 2007).

Employing a semiotic approach of cinema, this study focuses on the cartoons The New Spirit (1942), Der Fuehrer’s Face (1943) and Education for Death: The Making of the Nazi (1943). While American wartime …

Comparing Perceptions Of Motivation To Change: Clinicians Versus Their Substance-Abuse Clients, Arthur Tabrizi

Graduate Research Symposium (2010 - 2017)

Although some clients enter treatment voluntarily to seek intervention for their substance abuse problems, most enter under coercive external pressures that may be perceived by clinicians as less influenced by addressing substance abuse than by appeasing mandates from the judicial system, family, or employers. Little research has examined and compared how clinicians assess clients’ extrinsic and intrinsic motivation to change as opposed to how the clients assess themselves. A congruency between the two parties’ assessments may inform the quality of the therapeutic relationship and facilitate an effective treatment plan. Using the Circumstance, Motivation, and Readiness Scales (CMR) and availability sampling …

Acceptability Of Sexting In Same-Sex Relationships, Carly Shadid, Katherine M. Hertlein, Sarah M. Steelman

Graduate Research Symposium (2010 - 2017)

For individuals who identify as part of the LGB community, the Internet can be seen as a tool to take control of their lives, may promote self-esteem, and foster a sense of belonging. The purpose of the study was to learn about sexting practices on college campuses. It builds on the existing body of knowledge by attending specifically to sexting rather than the previous literature about engagement in sexual behavior online (see, for example, Daneback, Cooper, & Månsson, 2005). Findings indicated that sexting is viewed as more acceptable in same sex relationships as compared to heterosexual relationships.

Gilded Age Visual Media As The Impetus For Social Change: Jacob Riis’S Reform Photography And The Antecedents Of Documentary Film, Denitsa Yotova

Graduate Research Symposium (2010 - 2017)

This study examines the birth and evolution of the social documentary genre in visual media. It suggests that a mixture of ideology, technology, and social awareness are necessary for a successful social reform. It finds that despite the limitations of technology during the nineteenth century, social documentaries were produced long before they were part of the genres of photography and film. By focusing on the work of Danish photographer Jacob Riis and tracing the emergence of film, this study demonstrates a connection between documentary film and Riis’s social documentary photography and public slide exhibitions. The study concludes that in order …

Family-Farm Therapy: An Urban Therapy Clinic To Address The Multifaceted Needs Of Multi-Stressed Families And Their Surrounding Communities, Felisa M. Huene

Graduate Research Symposium (2010 - 2017)

Family-Farm Therapy incorporates a therapeutic clinic within an urban farming community site, and focuses on multi-stressed family systems and the larger community system. The goal is for systemic change within the family and the community by creating positive relationships and personal acceptance. Farming has traditionally been a family endeavor which makes it a unique environment to be utilized as metaphors for family systems, their interactions, behaviors, and structure. Multi-stressed families have socioeconomic hurdles that complicate their ability to adjust to change and crisis in their family. Farming addresses such hurdles by offering economic sustenance, increased physical health, and community acceptance. …

Explaining County Government Budget Transparency In An Age Of E-Government, Jonathan M. Birds, Leander D. Kellogg, E. Lee Bernick

Graduate Research Symposium (2010 - 2017)

This research seeks to explain budgetary transparency practices of individual US counties by examining the extent of information sharing with constituents via their websites. There are 3,138 counties and county-equivalents in the United States. This study evaluates a random sample of 400 US counties where 19% of the represented counties having populations of 100,000 or more residents, matching the same ratio of counties with populations of 100,000 or more residents nationally. We create a four-level categorical dependent variable measuring budget transparency. Using an ordered probit analysis with six independent variables we are able to explain the probability of counties having …

The Rhetoric Of Gay Christians: Matthew Vines And Reverend Nancy Wilson As Exemplars, Josu Miller

Graduate Research Symposium (2010 - 2017)

In the United States, there is a perception that the gay rights debate situates Christians against gay rights advocates. According to this perception, Christians oppose gay rights, because the Bible condemns homosexuality as a sin, and those who support gay rights do so using purely secular arguments. This perception of the gay rights debate is flawed and overly simplistic, because simply not all Christians oppose gay rights. In fact, there are multiple interpretations of biblical texts that support homosexuality and have caused a gay rights debate within the church that is as complex and intricate as gay rights debate outside …

Examining The Target Levels Of State Renewable Portfolio Standards, Laurence D. Helwig

Graduate Research Symposium (2010 - 2017)

At present 37 US states have passed Renewable Portfolio Standards (RPS) or have a legislative driven goal that supports investment in renewable energy (RE) technologies. Previous research has identified economic, governmental, ideological and infrastructural characteristics as key predictors of policy adoption and renewable energy deployment efforts (Carley, 2009; Davis & Davis, 2009; Bohn & Lant, 2009; Lyon & Yin, 2010). To date, only a few studies have investigated the target levels of renewable portfolio standards. Carley & Miller (2012) found that policies of differing stringencies were motivated by systematically different factors that included governmental ideology. The purpose of this study …

The Role Of Self Concept In Consumer Behavior, Marisa Toth

Graduate Research Symposium (2010 - 2017)

Understanding the processes that underlie consumer behavior has become an increasingly important area of research, especially for businesses and marketers. One of the most commonly studied variables believed to impact consumer behavior is self-concept.

The purpose of the current study is to examine the influence of self-concept in consumer behavior and identify factors that influence the relationship. Specifically, what is the relationship between different aspects of the self-concept and the consumption of publicly and privately consumed luxuries and necessities? Furthermore, how will this relationship be affected by the level of self-monitoring an individual displays?

The September 12, 2012 Rose Garden Address: President Barack Obama’S “9/11” Moment, Michael Eisenstadt

Graduate Research Symposium (2010 - 2017)

Albert Einstein once said memory is deceiving given it is colored by the events of today. The old adage “history repeats itself” fails to illustrate the powerful capacity for memory to sustain and revise historical events. Presidents often inject memories of the past into public address to define troubling situations in ways that broad, national audiences can make sense of them. Barack Obama’s Rose Garden Address rejuvenates and exploits the public memory of September 11 in three ways: by (1) situating the attack on the U.S. Consulate in Benghazi as an extension of its timeline; (2) reaffirming the identity of …

“We’Re Doin’ Ok” An Investigation Of Parental Account-Giving For Divorce-Related Financial Stress, Monique Makhlouf

Graduate Research Symposium (2010 - 2017)

Divorce is a prevalent issue facing many Americans today with nearly one-third of first marriages ending in divorce within 10 years, and 50% of all first marriages ending in divorce at some point in the lifespan (Frisby, Booth-Butterfield, Dillow, Martin, & Weber, 2012). Considerable evidence suggests that divorce can increase the likelihood of adverse effects on the psychological well-being of family members, particularly in families with children (Brown, Portes, & Christensen, 1989). Among the many issues that confront families going through a divorce is a shift in socioeconomic status or a loss of financial stability during and after a divorce …

Changing Awareness Of Human Trafficking, Roma Patel, Krystal Letourneau, M. Alexis Kennedy

Graduate Research Symposium (2010 - 2017)

The issue of human trafficking has received increased attention since the Trafficking Victims Protection Act was enacted in 2000. We assume that awareness is growing in the United States but this has not been tested. The current study measures increases in awareness about the issue of trafficking. Nearly 400 students were polled about their awareness in the spring of 2007. Attitudes towards government responses, awareness of the issue and support for victims were surveyed. The study was replicated 5 years later with over 500 new participants. This paper will analyze changes in awareness over time. Gender differences will also be …

A Critical Analysis Of Intellectual Disabilities And End-Of-Life Decision Making, Saritha Farris

Graduate Research Symposium (2010 - 2017)

Presently, research suggests the involvement of individuals with intellectual disabilities (IDs) in making end-of-life (EOL) decisions appears to be minimal (Ellison & Rosielle, 2008).

The reasons for the lack of involvement include but are not limited to communication challenges, lack of education on caring for individuals with IDs by the medical community, incorrect assumptions that the individual lacks cognitive capacity to consent, and fear of legal consequences if formal caregivers are accused of not providing enough care. (Wagemans et al., 2010).

These factors then often culminate in the individual with IDs having decisions made for them by someone else, whom …

Exploring The Community Factor Of Economic Resiliency, Al G. Gourrier

Graduate Research Symposium (2010 - 2017)

Resilience takes on many different meanings, but when we speak of the resilience of a market we are generally referencing the capability of that market’s capacity to respond, regroup and move forward, usually after an event or series of events that impede or encumber a market’s economic sustainability. The outcomes of a stable and performing market are indicated by its economic performance. Using economic indicators as a base, this study analyzes three markets as they recover from destabilizing events and attempt to respond, regroup and move forward. The study analyzes the Las Vegas, New Orleans and Detroit markets from an …

Long May She Reign: A Rhetorical Analysis Of Gender Expectations In Disney’S Tangled And Disney/Pixar’S Brave, Caitlin J. Saladino

Graduate Research Symposium (2010 - 2017)

This project addresses messages about gender expectations in Disney princess narratives. The two films included in my project are Tangled (2010) and Brave (2012), which feature the most recently inducted princesses to the marketed Disney Princess line (Rapunzel and Merida, respectively). Using genre as an organizing principle, I argue that Rapunzel and Merida are different from the past Disney princesses (Snow White, Cinderella, Ariel, Jasmine, etc.) because their narratives reflect new ideas about gender expectations in modern society. The central tension appearing in both films is the opposition between the image of woman as traditional, domestic, and dependent and woman …

Environmental Correlates Of Physical Activity Among African-American Adults, Tim Bungum, Jennifer Pharr, Paulo S. Pinheiro, Maria Azzarelli

Nevada Journal of Public Health

The purpose of this cross-sectional study was to identify perceived environmental correlates of meeting physical activity guidelines among African-American adults living in Southern Nevada. Trained interviewers phoned potential participants who lived in the 12 zip codes of Clark County, Nevada with the highest proportions of African-American residents. Respondents (n=237) answered 52 health-related and demographic questions. Slightly less than 50% of participants met physical activity guidelines. A factor analysis procedure produced two environmental variables, neighborhood safety and environmental supports for physical activity. Age, gender and educational attainment (p<.05) predicted the meeting of those guidelines (R2=.214), while neighborhood support for physical activity, neighborhood safety, and BMI failed to do so. This finding suggests that environmental factors are not strong predictors of physical activity among African- American adults, although environmental supports for physical activity approached significance. Future studies should consider assessing additional aspects of the built environment as an influence on physical activity.

The Success Of Gay–Straight Alliances In Waterloo Region, Ontario: A Confluence Of Political And Social Factors, Alex St. John, Robb Travers, Lauren Munro, Renato M. Liboro, Margaret Schneider, Carrie L. Greig

Psychology Faculty Research

This article outlines how gay–straight alliances (GSAs) work to connect youth with community resources, and outlines the political and social context of GSAs in Waterloo Region, Ontario, Canada. Fifteen individuals (youth, teachers, and a lesbian, gay, bisexual, transgender, and queer [LGBTQ] youth service provider) participated in interviews about the role of GSAs in creating supportive school environments for LGBTQ youth and their allies. Analyses of the interview data found that, apart from providing direct support to LGBTQ students, GSAs in Waterloo Region decrease isolation by connecting youth with other LGBTQ community members, events, and resources. This article discusses how the …

America's Role In A Changing World, Bruce Jones

Brookings Scholar Lecture Series

For over sixty years the United States has led an international order that provided the underpinnings of peace, security, and economic prosperity. Today, that order is under strain from a variety of sources: the rise of new powers, an economic crisis, resource scarcity, technological innovations, rising nationalism, territorial disputes, and transnational challenges. This lecture will examine these pressures and ask how the United States can reform the international order so it plays as constructive a role in the 21st century as it did in the 20th.

Mountain Monitor - 4th Quarter 2013, Kenan Fikri, Mark Muro

Mountain Monitor Quarterly

The quarter’s Mountain Monitor finds that the pace of economic recovery in the Mountain West region’s major metropolitan areas converged toward that of the rest of the nation in the last quarter of 2013.

While quarterly performance on the Monitor’s four indicators of economic recovery—employment, output, the unemployment rate, and house prices—varied considerably across the 10 major metro areas of the region, their combined performance broadly slowed to track with the rate of national economic recovery. The quarter’s average job growth remained unchanged in the region at 0.4 percent as the national economy caught up. The gap between the national …

America Moves: Transportation And Public Policy In The United States, Adie Tomer

Brookings Scholar Lecture Series

The United States is in a perpetual state of motion. Every day, Americans drive over 8 billion miles, board over 20,000 flights, and ship over 45 million tons of freight. But what drives all of this physical movement? And what is the relationship to public policy? This presentation will begin to answer those questions, utilizing a combination of quantitative metrics and policy analysis to explain how, where, and why Americans move. It will outline driving habits, and the disruptive moment every metropolitan area and state faces due to federal gridlock. It will map aviation patterns, and the emerging presence of …

Does Access To Information Technology Make People Happier? Insights From Well-Being Surveys From Around The World, Carol Graham, Milena Nikolova

Brookings Scholar Lecture Series

This lecture summarizes new research on the relationship between access to cell phones, TV, and the internet and subjective well-being worldwide. Technology access is positive for well-being in general, but with diminishing marginal returns for those who already have much access. It is also associated with increased stress and anger among cohorts for whom access to the technologies is new. The increased financial inclusion in very poor countries that comes with cell phones and mobile banking also has effects on well-being. Well-being levels are higher in the countries with higher levels of access to mobile banking, but so are stress …

Tax Reform In Nevada: Ideas For Creating A More Stable Revenue Structure, J. T. Creedon

Brookings Mountain West Publications

Recurring and fluctuating levels of economic activity known as the business cycle have a profound impact on state legislators trying to balance their finances. They result in higher unemployment, declines in revenues and a corresponding increase in the need for social welfare and public services. This makes state budgeting particularly complex during times of contraction when the state needs to do more with less. Nevada, with its limited tax base, biennial budget making, and overreliance on an industry that is highly volatile in response to economic fluctuations, experiences particularly dramatic upswings and shortfalls. Contractionary fiscal policies such as tax increases …

English Language Learners In Nevada, Robin Gonzales

Brookings Mountain West Publications

While leading the rest of the country in population growth, immigration, and increasing ethnic and linguistic diversity, Nevada’s mostly Latin American population experiences high poverty, low educational attainment, and high employment. As a result, Nevada has increasingly high numbers of English Language Learner students (ELLs) – students who speak a language other than English at home – and show low educational attainment compared to their English speaking counterparts. According to a 2013 report from the Lincy Institute of the University of Nevada, Las Vegas, if the state wants to reverse its populations’ dismal educational attainment and poor national rankings in …
