Unified M-Estimation Of Fixed-Effects Spatial Dynamic Models With Short Panels, Zhenlin Yang

Research Collection School Of Economics

It is well known that quasi maximum likelihood (QML) estimation of dynamic panel data (DPD) models with short panels depends on the assumptions on the initial values, and a wrong treatment of them will result in inconsistency and serious bias. The same issues apply to spatial DPD (SDPD) models with short panels. In this paper, a unified Mestimation method is proposed for estimating the fixed-effects SDPD models containing three major types of spatial effects, namely spatial lag, spatial error and space-time lag. The method is free from the specification of the distribution of the initial observations and robust against nonnormality …

Institutional Complementarity Across Countries In Bilateral Fdi Flows: Theory And Evidence, Pao-Li Chang

Research Collection School Of Economics

This paper builds a theory to characterize the comparative advantage of MNEs based in countries of different institutional qualities. It is shown that MNEs headquartered in countries of poorer state institutions will invest more in `informal institutions; and choose to undertake FDI in countries of weaker institutions. At the aggregate, MNEs on average generate more net profits in countries of weaker institutions, the poorer the institutional environment at home. I conduct an extensive test of the theory using bilateral FDI volume for 219 economies in year 2001-2010. The results indicate a statistically significant and robust institutional complementarity effect in bilateral …

New Methodology For Constructing Real Estate Price Indices Applied To The Singapore Residential Market, Liang Jiang, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper develops a new methodology for constructing a real estate price index that utilizes all transaction price information, encompassing both single-sales and repeat-sales. The method is less susceptible to specification error than standard hedonic methods and is not subject to the sample selection bias involved in indexes that rely only on repeat sales. The methodology employs a model design that uses a sale pairing process based on the individual building level, rather than the individual house level as is used in the repeat-sales method. The approach extends ideas from repeat-sales methodology in a way that accommodates much wider datasets. …

Adaptive Nonparametric Regression With Conditional Heteroskedasticity, Sainan Jin, Liangjun Su, Zhijie Xiao

Research Collection School Of Economics

In this paper, we study adaptive nonparametric regression estimation in the presence of conditional heteroskedastic error terms. We demonstrate that both the conditional mean and conditional variance functions in a nonparametric regression model can be estimated adaptively based on the local profile likelihood principle. Both the one-step Newton-Raphson estimator and the local profile likelihood estimator are investigated. We show that the proposed estimators are asymptotically equivalent to the infeasible local likelihood estimators [e.g., Aerts and Claeskens (1997) Journal of the American Statistical Association 92, 1536-1545], which require knowledge of the error distribution. Simulation evidence suggests that when the distribution of …

Csi Agent On A Mission Game App, Ju Mae Rosie Ching

Research Collection School Of Economics

CSI is a one-of-a-kind and first-ever iPad gaming app released early August, with the flash game at http://www.rosieching.com/csi. My primary objective was to realize my dreamed-up “MISSION STATISTICS” theme for students to apply their skills in hypothesis tests and linear regression. Another is the incorporation of their CSI results into an “enrichment 5%” of their grades. The harder an agent works, the higher his score, the sweeter the fruit of the labour which students always show massive enthusiasm for. It is also critical that students review their real-time progress, and I have ensured that in every step of each country’s …

On The Unreliability Of Bug Severity Data, Yuan Tian, Nasir Ali, David Lo, Ahmed E. Hassan

Research Collection School Of Computing and Information Systems

Severity levels, e.g., critical and minor, of bugs are often used to prioritize development efforts. Prior research efforts have proposed approaches to automatically assign the severity label to a bug report. All prior efforts verify the accuracy of their approaches using human-assigned bug reports data that is stored in software repositories. However, all prior efforts assume that such human-assigned data is reliable. Hence a perfect automated approach should be able to assign the same severity label as in the repository – achieving a 100% accuracy. Looking at duplicate bug reports (i.e., reports referring to the same problem) from three open-source …

A Cooperative Coevolution Framework For Parallel Learning To Rank, Shuaiqiang Wang, Yun Wu, Byron J. Gao, Ke Wang, Hady W. Lauw, Jun Ma

Research Collection School Of Computing and Information Systems

We propose CCRank, the first parallel framework for learning to rank based on evolutionary algorithms (EA), aiming to significantly improve learning efficiency while maintaining accuracy. CCRank is based on cooperative coevolution (CC), a divide-and-conquer framework that has demonstrated high promise in function optimization for problems with large search space and complex structures. Moreover, CC naturally allows parallelization of sub-solutions to the decomposed sub-problems, which can substantially boost learning efficiency. With CCRank, we investigate parallel CC in the context of learning to rank. We implement CCRank with three EA-based learning to rank algorithms for demonstration. Extensive experiments on benchmark datasets in …

Without Mandate For Conquest: A Transnational Comparison Of Toni Morrison's Song Of Solomon And Isabel Allende's Eva Luna, Vivianna Noelle Orsini

UNLV Theses, Dissertations, Professional Papers, and Capstones

In our current age of globalization, multiculturalism is a key component of human relations. Place, when thought of as a geographic concept is more than just coordinates on a map, it is a concentration of a set of social relations. Geographers use this information to see how places are relational to other places. Morrison and Allende are relational because of their consciousness of place especially exhibited in Song of Solomon and Eva Luna. This project examines the disparate histories, politics, and landscapes that both authors emerged from, and argue the complexity of their work stems from thinking geographically, their conscious …

The Lived Experience Of Nurses Working In A Modified Therapeutic Community, Victoria Lynn Plagenz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Today over one million U. S. prisoners are being held in federal and state systems for substance use-related crimes. The financial, social, and emotional costs have turned policymakers’ attention to rehabilitation rather than incarceration. In an attempt to meet the challenge of recovery from addiction, prison systems around the nation have explored various options, including residential treatment programs. One such form of residential treatment is the modified therapeutic community (MTC) where inmates participate in a nine-month, cognitive-based treatment program. This model focuses on incarcerated individuals, addicted to substances, to assist them in developing behaviors to reduce antisocial peer associations and …

Ediacaran Ocean Redox Evolution, Swapan Kumar Sahoo

UNLV Theses, Dissertations, Professional Papers, and Capstones

The relative role that environmental versus intrinsic biological factors played in

shaping the history of life on Earth is a fundamental but unanswered question in the

natural sciences. Most famously, it has been heavily debated if the emergence and

diversification of early animals during the Ediacaran Period (ca. 635–541 Ma) was tied to

a rise in atmospheric-oceanic oxygen levels. Temporally discontinuous geochemical data and patchy fossil record in literature are inadequate to chart the Ediacaran redox history and its causal relationship with the biotic evolution. My PhD study aims for a multiproxy geochemical record within a well-established stratigraphic framework of …

Ecosystem Response To Recent Climate Change In Alpine Environments, Patrick Shawn Sawyer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent variations in meteorological conditions indicate the earth’s climate is changing in ways that can impact delicate ecological balances in sensitive regions. These impacts threaten the essential services provided by such ecosystems. Determining how climate changes are affecting the biosphere is essential to adapt and mitigate harmful consequences. In order to mitigate the negative effects of climate change and adapt to shifting ecological resource constraints, it is imperative to locate such changes and determine vulnerability of ecological resources to changing environmental conditions.

Identifying climate driven ecological changes faces numerous challenges given the reliance on vegetation indices as the primary measure …

"Because Of My Identity:" Valuing The Experiences Of Latina Students In The Culturally Responsive Service-~Learning Classroom, Janessa Schilmoeller

UNLV Theses, Dissertations, Professional Papers, and Capstones

This qualitative case study examined the experiences of three Latina students in a higher education service-learning program. A review of service-learning literature found limited research dedicated to understanding the qualitatively different experiences of students of color operating in historically and predominantly white higher education institutions’ service-learning programs. Though the diversity benefits of service-learning are documented, research is inconclusive on whether service-learning program culture adequately meets the needs of all racially/ethnically diverse students. The study utilized student interviews and classroom observation to build understanding of the unique experiences of three Latina students participating in a service-learning course taught by a Latina …

Rewetting Of Artificially Desiccated Soils: Effect Of Gravity On Vapor-Phase Diffusion, Taylor Arland Ball

UNLV Theses, Dissertations, Professional Papers, and Capstones

Soil desiccation has been suggested as an economically viable alternative for stabilizing water soluble contaminants in deep vadose zones such as at the Hanford Site. This approach would result in a large volume of the vadose zone being dried out in an effort to eliminate the transport mechanism for aqueous phase contaminants. Protecting the top and sides of the desiccated vadose zone from rewetting is a realistic possibility; however, it would be extremely difficult to restrict the upward migration of water from beneath the desiccated zone. One scenario related to the rewetting of the desiccated soil involves the upward migration …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The climate is continually changing for the worse as there are poor decisions being made in the rapidly constructed built environment. In an effort to reduce the impact on the built environment, the typical residential roof assemblies that are currently being used in the U.S. desert southwest are not the best for the environment. Through research and simulations, this

paper compares several residential roof assemblies to the standard code compliant construction and provides cost breakdowns of simple payback and cost of save energy for each of the simulated systems. A case study was also designed for the U.S. Department of …

Assessing The Importance Of Nurse Plant Associations To The Growth Of Pre-~Reproductive Yucca Brevifolia, Eric James Chameroy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Facilitation and competition among plant species, in addition to abiotic factors, play an important role in determining plant community structure in arid and semi-arid environments. I conducted a study in Dry Lake Valley, Lincoln County, Nevada, USA to investigate the importance of nurse plant associations to pre-reproductive Yucca brevifolia (Joshua tree). Dry Lake Valley lies within a transition desert between the Mojave and Great Basin Deserts with ecotonal plant communities consisting of species representative of both deserts. A vegetation survey described the communities in which this study was conducted as a Y. brevifolia woodland dominated by an understory of Ephedra …

Effect Of Psychological Empowerment And Transformational Leadership On Organizational Commitment, Nurshahira Ibrahim, Azman Ismail, Nurasilah Kithuru Mohamed, Siti Salwa Salim

Makara Human Behavior Studies in Asia

According to recent literature that relates to organizational leadership, transformational leadership consists of three important elements: idealized influence, individual consideration and intellectual stimulation. Extant studies in this area highlighted that the ability of the leaders in implementing these transformational processes (to execute organizational functions) may have a significant impact on individual outcome especially organizational commitment. Although this relationship has been studied, the mediating role of transformational leadership has taken a less prominent role in organizational leadership model. Recent studies on organizational leadership have emphasized that transformational leadership has three important characteristics: idealized influence, individual consideration and intellectual stimulation.

Making Heat Visible: Promoting Energy Conservation Behaviors Through Thermal Imaging, Julie Goodhew, Sabine Pahl, Tim Auburn, Steve Goodhew

School of Psychology

Householders play a role in energy conservation through the decisions they make about purchases and installations such as insulation, and through their habitual behavior. The present U.K. study investigated the effect of thermal imaging technology on energy conservation, by measuring the behavioral effect after householders viewed images of heat escaping from or cold air entering their homes. In Study 1 (n = 43), householders who received a thermal image reduced their energy use at a 1-year follow-up, whereas householders who received a carbon footprint audit and a non-intervention control demonstrated no change. In Study 2 (n = 87), householders were …

Tunneling A Pulmonary Artery Graft: A Simplified Way To Insert And Remove A Temporary Right Ventricular Assist Device, Pankaj Saxena, Silvana F Marasco

The Texas Heart Institute Journal

Right ventricular failure can occur early or late after left ventricular assist device implantation. Support with a right ventricular assist device is needed in patients whose right ventricular failure does not respond to conservative management. The use of a temporary right ventricular assist device can enable the recovery of right ventricular function and avoid the use of a more permanent biventricular assist device, which is associated with complications and higher costs. We present our technique of instituting temporary right ventricular assist device support in patients who have undergone left ventricular assist device implantation.

Equity And Excellence: The Story Of Lake Shore Community High School's Quest For Racial Justice In Education, Marcus Campbell

Dissertations

Institutional racism is integral to U.S. social structure, including the public schools. Instituting a limited high school detracking program as a strategy to deal with racial achievement disparities faced strong community resistance. Leadership and a perfect storm of social and political factors made successful implementation of a detracking initiative possible. School community leaders and staff were interviewed about their experiences of systemic change to further access for students of color to honors classes. Results suggest some leadership qualities and characteristics that facilitated the change; the external factors that contributed to the successful change for racial equity are also detailed.

The Legacy Of Rudolph Ackermann And Nineteenth-Century British Literary Annuals, Katherine D. Harris

Faculty Research, Scholarly, and Creative Activity

By November 1822, the British reading public had already voraciously consumed both Walter Scott’s expensive novels and Rudolf Ackermann’s exquisite lithographs. The next decade, referred to by some scholars as dormant and unproductive, is in fact bursting with Forget Me Nots, , Keepsakes, and Literary Souvenirs. By wrapping literature, poetry, and art into an alluring package, editors and publishers saturated the market with a new, popular, and best-selling genre, the literary annual. In this excerpt from the introduction to Forget Me Not: The Rise of the British Literary Annual, the foundations of the literary annual, its …

Predictors Of Texas Police Chiefs’ Satisfaction With Police-Prosecutor Relationships, Brenda I. Rowe

Criminology and Criminal Justice Faculty Publications (Archived)

Although strain in police-prosecutor relationships may be built into the criminal justice system’s checks and balances, the administration of criminal justice can benefit from the adoption of practices which improve these working relationships. A first step towards the adoption of such practices can be taken by first adding to the knowledge base regarding this understudied topic. Using a survey of a state-wide sample of Texas police chiefs, this exploratory study identifies which aspects of police-prosecutor interaction styles are predictors of police chiefs’ satisfaction with police-prosecutor relationships. Results indicate that perceived level of police input in prosecutors’ plea bargain and charging …
