Factors Affecting The Seismic Behavior Of Segmental Precast Bridge Columns, Haitham Dawood, Mohamed Elgawady, Joshua Hewes

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This manuscript discusses the design parameters that potentially affect the lateral seismic response of segmental precast post-tensioned bridge piers. The piers consist of precast circular cross section segments stacked one on top of the other with concentric tendons passing through ducts made in the segments during casting. The bottommost segments of the piers were encased in steel tubes to enhance ductility and minimize damage. An FE model was used to investigate different design parameters and how they influence the lateral force — displacement response of the piers. Design parameters investigated included the initial post-tensioning stress as a percentage of the …

Homogenous Ensemble Phonotactic Language Recognition Based On Svm Supervector Reconstruction, Wei-Wei Liu, Wei-Qiang Zhang, Michael T. Johnson, Jia Liu

Electrical and Computer Engineering Faculty Research and Publications

Currently, acoustic spoken language recognition (SLR) and phonotactic SLR systems are widely used language recognition systems. To achieve better performance, researchers combine multiple subsystems with the results often much better than a single SLR system. Phonotactic SLR subsystems may vary in the acoustic features vectors or include multiple language-specific phone recognizers and different acoustic models. These methods achieve good performance but usually compute at high computational cost. In this paper, a new diversification for phonotactic language recognition systems is proposed using vector space models by support vector machine (SVM) supervector reconstruction (SSR). In this architecture, the subsystems share the same …

Effective Instructional Strategies Utilized In Successful And High Performing Secondary Schools In The Southern Region Of Mississippi, Jeanifer Lynn Pearson

Dissertations

The schools in the United States have implemented measures intended to close the achievement gap for over fifty years (Solomon, 2009). The mandates handed down by the federal government cannot be altered. Therefore, schools are required to determine specific measures that increase student academic success. Prior research has demonstrated that schools can be successful if effective leadership at the district, school, and classroom level was present (Gregory, 2003; Johnson, Livingston, & Schwartz, 2000). At the classroom level, it was the leadership of the individual teacher to determine the creation of innovative techniques aimed at academic success of all students (Farr …

The Influence Of Observational Learning On Self-Reported Physical Activity, Self-Efficacy For Physical Activity, And Health-Related Fitness Knowledge For Physical Activity, Charles Gregory Bullock

Dissertations

The obesity epidemic has caused tremendous burden to our economy and healthcare system. Physical activity is one method that can reduce the obesity rate. However, physical activity declines in high school and does not recover. The likelihood of adolescents continuing their involvement in physical activity depends on how they navigate the highs and lows of their physical activity experiences (Feltz & Magyar, 2006). The purpose of this study is to look at the role of observational learning in physical activity and behaviors in an adolescent population. Specifically, this research examines the influence of observational learning on self-reported physical activity, self-efficacy …

On Bias In The Estimation Of Structural Break Points, Liang Jiang, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

Based on the Girsanov theorem, this paper obtains the exact Önite sample distribution of the maximum likelihood estimator of structural break points in a continuous time model. The exact Önite sample theory suggests that, in empirically realistic situations, there is a strong Önite sample bias in the estimator of structural break points. This property is shared by least squares estimator of both the absolute structural break point and the fractional structural break point in discrete time models. A simulation-based method based on the indirect estimation approach is proposed to reduce the bias both in continuous time and discrete time models. …

Structural Change Estimation In Time Series Regressions With Endogenous Variables, Junhui Qian, Liangjun Su

Research Collection School Of Economics

We propose to apply the group fused Lasso to estimate time series models with endogenous regressors and an unknown number of breaks. It can correctly determine the number of breaks and estimate the break dates asymptotically. Simulations and applications are given.

Testing The Martingale Hypothesis, Peter C. B. Phillips, Sainan Jin

Research Collection School Of Economics

We propose new tests of the martingale hypothesis based on generalized versions of the Kolmogorov–Smirnov and Cramér–von Mises tests. The tests are distribution-free and allow for a weak drift in the null model. The methods do not require either smoothing parameters or bootstrap resampling for their implementation and so are well suited to practical work. The article develops limit theory for the tests under the null and shows that the tests are consistent against a wide class of nonlinear, nonmartingale processes. Simulations show that the tests have good finite sample properties in comparison with other tests particularly under conditional heteroscedasticity …

Executive Overreach By Minority Governments, Madhav S. Aney, Shubhankar Dam

Research Collection School Of Economics

A provision in the Indian constitution allows the executive to make laws in the event oneof the two houses of parliament is not in session. This provision was intended to allow theexecutive to act in case there’s an immediate legislative necessity and the parliament cannotbe convened. Using a bargaining model with asymmetric information we show how partieswithin the parliament may reach an agreement on legislations when the ruling party does notcommand a majority (minority government). The model makes predictions about lawmakingpatterns by the legislature when the parliament is in session, and ordinances by the executivewhen the parliament is not in …

Impact Of Guided Inquiry On Tenth Graders’ Understanding Of Chemical Bonds, Badreya Esmaeil Abdul Raheem Al Zarooni

Theses

Students' understandings of scientific conceptions have been of considerable interest to science education researchers and science teachers in recent years. Accordingly, many scholarly studies have been conducted on the students' understandings and misunderstandings, particularly, those concerned with chemistry. For the present study, the term misconception is used to encompass both alternative responses that arise from formal intervention; such as classroom study, as well as those resulted from the students own interactions with, and observations of their surrounding environment. The main purpose of this study is to investigate the understanding of the Grade-10 students about the concepts and misconception regarding the …

A Metrics Suite Of Cloud Computing Adoption Readiness, Robert J. Kauffman, Dan Ma, Martin Yu

Research Collection School Of Computing and Information Systems

Recent research on cloud computing adoption indicates that there has been a lack of deep understanding of its benefits by managers and organizations. This has been an obstacle for adoption. We report on an initial design for a firm-level cloud computing readiness metrics suite. We propose categories and measures to form a set of metrics to measure adoption readiness and assess the required adjustments in strategy and management, technology and operations, and business policies. We reviewed the relevant interdisciplinary literature and interviewed industry professionals to ground our metrics based on theory and practice knowledge. We identified four relevant categories for …

Probabilistic Latent Document Network Embedding, Tuan M. V. Le, Hady W. Lauw

Research Collection School Of Computing and Information Systems

A document network refers to a data type that can be represented as a graph of vertices, where each vertex is associated with a text document. Examples of such a data type include hyperlinked Web pages, academic publications with citations, and user profiles in social networks. Such data have very high-dimensional representations, in terms of text as well as network connectivity. In this paper, we study the problem of embedding, or finding a low-dimensional representation of a document network that "preserves" the data as much as possible. These embedded representations are useful for various applications driven by dimensionality reduction, such …

Orientalism And "Authentic Homosexual": How "The Closet" Reinforces Hegemonic Knowledge And Binary Logic, Contributing To The Invisibility Of Non-Conforming Gender And Sexual Identities, Michelle Bonapace-Potvin

Theses and Dissertations

The critique of Orientalism's binary logic finds a complementary analysis in the questioning of static sexual and gender categories. There is already significant research that points to these intersectional critiques—for instance, Joseph Massad's Desiring Arabs and Jasbir K. Puar’s Terrorist Assemblages: Homonationalism in Queer Times. In this paper, I will use analyses of Orientalism to review the ways in which hegemonic knowledge and binary logic contribute to the invisibility of non- conforming gender and sexual identities. In other words, I will use the language and lens of critiques of Orientalism to observe, analyze, and comment on the current politics of …

Performance Or Processing? Effects Of Levels Of Processing And Divided Attention On Memory-Related Eye Movements, Wei An

UNLV Theses, Dissertations, Professional Papers, and Capstones

Human memories are expressed either with or without consciousness, termed as explicit and implicit memories, respectively. Different encoding manipulations like levels of processing and divided attention have been shown to affect explicit memories but not implicit memories. These dissociations, however, were only found between explicit and implicit item memories. Whether explicit and implicit relational memories will exhibit similar dissociations is still unknown. In order to determine whether explicit and implicit relational memories dissociated in a similar way as explicit and implicit item memories, the levels of processing and divided attention were manipulated in the present study and participants' relational memories …

Ore Classification And Breccia Formation In The 144 Zone Gold Deposit: A Chemical Replacement Model, Bare Mountain Range, Nevada, William Thomas Fischer

UNLV Theses, Dissertations, Professional Papers, and Capstones

The 144 Zone is an oxidized, breccia-hosted, disseminated gold deposit that formed along the contact between Early Cambrian Carrara Formation limestone and overlying Bonanza King Formation dolomite within the Bare Mountain range in southern Nevada. Gold mineralization occurs within a breccia body that contains a variety of breccia types. Research goals of this project included classifying clay, oxide and other minerals as well as breccia types to identify the habits of gold mineralization and the minerals associated with gold. Research was also aimed at determining the paragenesis of Au mineralization and brecciation in the 144 Zone. Underground mapping provided spatial …

Digital Behavior Intervention Plans: Effects On General Education Teacher Fidelity Of Implementation, Christopher G. Holcomb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students with disabilities often have behavior that interferes with classroom learning. Serious problem behaviors are identified as the most significant factor interfering with learning in the classroom. Unfortunately, chronic behaviors often lead to a student dropping out of school. Current research typically focuses on areas of intervention for these students with little attention towards teacher fidelity of implementation of these interventions. Because of this, student's behavior intervention plans may not show effectiveness (e.g., progress monitoring, data driven decisions). It is important that researchers begin to explore systematic improvements in fidelity of implementation of behavior intervention plan components for general education …

Spectral Decomposition Of The Scattered Light Due To Deposits On The Solar Panel Surface, And Cross Correlated To Power Loss, Suzanna Ho

UNLV Theses, Dissertations, Professional Papers, and Capstones

The electric energy generated by solar panels declines due to dust particulates, bird deposits, water spots, and other contaminants that inhibit sunlight absorption and promote light scattering. As part of our research, we use cameras to capture images of solar panels, and analyze the images to detect the amount of scattered light. The more scattered light there is, the less light there is to penetrate the solar panel glass and reach the part of the panel that converts incident light to electric energy; therefore, less energy is generated. In this paper, we discuss the classification algorithm we developed to classify …

Postural Sway And Brain Hemispheric Power Spectral Density Under Different Attentional Focus Conditions, Sharon Jalene

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to determine the differences, if any, in the root mean square error (RMSE) of postural sway and hemispheric power spectral density (PSD) in the alpha and beta bands (8-12Hz and 12-25Hz) during different conditions of attentional focus (i.e., internal focus (IF), and external focus (EF) and a control condition (C)). Previous studies have shown that the adoption of IF and EF significantly alter motor performance and that EF promotes automaticity (Wulf, 2013). Sports performance and balance studies utilizing EEG spectral analyses report increased alpha oscillations during expert performance and stable balance and increased beta …

Maritime Piracy And Armed Robbery Confrontations Across The Globe: Can Crew Action Shape The Outcomes?, Justin Stewart Lewis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Abstract

The recent tightening of military budget constraints has called into question the feasibility of costly multilateral naval intervention used to combat maritime piracy off the eastern coast of Africa. Though past studies agree that the transformation of the Somali economy and government is crucial for a long-term solution to piracy in this part of the world, short to medium-run solutions are needed to bridge the gap. Such solutions should be fiscally sensible and serve as effective deterrents, as well as be applicable in addressing the problem of piracy and maritime armed robbery in other parts of the globe.

Thermal Impacts Of Salt On Sandstones And Mudstones In The Lusitanian Basin, Portugal, Brett Perry

UNLV Theses, Dissertations, Professional Papers, and Capstones

In order to assess the impact of salt structures on paleotemperatures in adjacent sedimentary rocks, a field based study which quantified thermally driven diagenetic products as a function of distance from salt was undertaken. Several salt diapirs are now exposed at the surface of the Earth within the Lusitanian Basin and offered a unique opportunity to document paleothermal anomalies by studying thermally controlled diagenesis in adjacent, exposed Upper Jurassic rocks. Four transects were chosen within Upper Jurassic rocks that contained both sandstones and mudstones. Quartz cementation and albitization of feldspars, both of which are thermally driven processes, were quantified in …

An Examination Of Implicit Values In Cornerstone Student Affairs Textbooks, Nathan Slife

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of student affairs is properly cautious about indoctrination. Indoctrination, after all, clearly contradicts the field's ethical statements and standards. These cautions have led student affairs researchers to investigate explicit values in the field to prevent explicit forms of indoctrination. However, recent investigations of implicit values in the discipline of psychology have revealed a potential new source of indoctrination not currently studied in student affairs. Specifically, psychological researchers have identified a system of implicit values called liberal individualism that has been found to be pervasive throughout the psychological discipline. Given the widely acknowledged link between student affairs and psychology, …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Due to the complex nature of assessment in critical pedagogy practices, continued research is necessary in order to investigate the constantly evolving nature of education and the way we come to know how people learn. To research assessment in the critical classroom requires both instructor and students. This qualitative multiple case study investigated impacts of a grading contract as a form of assessment on student writing in a Basic Writing composition course. This study examined the impacts of a grade contract on students' writing, motivation for writing, revision practices, authorship and expectations of a Basic Writing composition course. Through a …

The Relevance Of Culture In Politics: The Application Of Cultural Studies Using The Strategic Culture Method, Elizabeth G. Wilson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

American Studies scholars have long been aware that their interdisciplinary studies reach far beyond Americana. The fields of folklore, English, history, political science and anthropology have all been enveloped under the American Studies umbrella. Public perceptions tend to assume that scholars engaged in these fields are limited to work within academia.

Empathic Accuracy And Aggression In Couples: Individual And Dyadic Links, Shiri Cohen, Marc S. Schulz, Sabrina R. Liu, Muhannad Halassa, Robert J. Waldinger

Psychology Faculty Research and Scholarship

This study examined links between intimate partner aggression and empathic accuracy – how accurately partners can read one another’s emotions – during highly affective moments from couples’ (N = 109) video recall of laboratory-based discussions of upsetting events. Less empathic accuracy between partners was generally related to higher levels of aggression by both partners. More specific patterns emerged based on the type of aggression and emotion being expressed. Women’s poorer ability to read their partners’ vulnerable and positive emotions was linked to both men’s and women’s greater physical and psychological aggression. Moreover, women’s inaccuracy in reading their partner’s hostility was …

Educational Practices, Funding, And The Implementation Of A Reading First Program, Maria Maricela Rodriguez-Salaiz

Theses and Dissertations - UTB/UTPA

The National Reading Panel (NICHD, 2000) found that too many children struggle with learning to read. Through a Congressional mandate, the panel identified key skills and methods that were central to reading achievement in the grades kindergarten through third grade. According to the United States Department of Education (USDE) Summary of Discretionary Funds (2008b), over $6 billion were allocated to the schools to implement the research based strategies from 2002 to 2008. States throughout the country showed gains from the states’ first year of implementation to 2008 in grades 1-3 in comprehension assessments.
