Spectroscopic Studies Of Melamine At High Pressure, Martin Donald Galley

UNLV Theses, Dissertations, Professional Papers, and Capstones

We have performed mid- and far- Infra Red (IR) absorption, Raman spectroscopy, and angular dispersive x-ray diffraction (XRD) studies on melamine under high pressure and room temperature. We have verified the presence of two prior reported phase transitions, the first between 1-2 GPa, and the second between 7-9 GPa. We have also found evidence of a third unreported phase transition between 14-16 GPa, during which, there was a sudden disappearance of all low energy peaks (^-1 ) in both the Raman and IR spectra. The far-IR peak movement experiences a discontinuity as the rate of peak movement suddenly changes. …

Processj: A Process-Oriented Programming Language, Matthew Sowders

UNLV Theses, Dissertations, Professional Papers, and Capstones

Java is a general purpose object-oriented programming language that has been widely adopted. Because of its high adoption rate and its lineage as a C-style language, its syntax is familiar to many programmers. The downside is that Java is not natively concurrent. Volumes have been written about concurrent programming in Java; however, concurrent programming is difficult to reason about within an object-oriented paradigm and so is difficult to get right.

occam -π is a general purpose process-oriented programming language. Concurrency is part of the theoretical underpinnings of the language. Concurrency is simple to reason about within an occam -π application …

Ensemble Methods For Dynamic Data Assimilation Of Chemical Observations In Atmospheric Models, Adrian Sandu, Emil Constantinescu, Gregory R. Carmichael, Tianfeng Chai, Dacian Daescu, John H. Seinfeld

Mathematics and Statistics Faculty Publications and Presentations

The task of providing an optimal analysis of the state of the atmosphere requires the development of dynamic data-driven systems (DDDAS) that efficiently integrate the observational data and the models. Data assimilation, the dynamic incorporation of additional data into an executing application, is an essential DDDAS concept with wide applicability. In this paper we discuss practical aspects of nonlinear ensemble Kalman data assimilation applied to atmospheric chemical transport models. We highlight the challenges encountered in this approach such as filter divergence and spurious corrections, and propose solutions to overcome them, such as background covariance inflation and filter localization. The predictability …

Electrochemistry Of Pani/Metal Composites In Basic Solutions, Tamthinhan Quy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Polyaniline (PANI) has been extensively investigated due to its unique conductivity, which is primarily dependent on the oxidation state of the material and the solution pH. PANI is an insulator when it is oxidized, and the solution pH exceeds four. Numerous attempts to extend PANI's conductivity to neutral and alkaline environments have been unsuccessful. However, our previous study has demonstrated that PANI/Pd composite is conductive and catalytically active in a basic solution, pH ∼ 12. Therefore, the conductivity and the electrochemical properties of PANI composites including PANI/Au, PANI/Pd and PANI/Pt were evaluated in basic solutions. The fundamental studies of PANI/metal …

State Space Model With Hidden Variables For Reconstruction Of Gene Regulatory Networks, Xi Wu, Peng Li, Nan Wang, Ping Gong, Edward J. Perkins, Youping Deng, Chaoyang Zhang

Faculty Publications

Background: State Space Model (SSM) is a relatively new approach to inferring gene regulatory networks. It requires less computational time than Dynamic Bayesian Networks (DBN). There are two types of variables in the linear SSM, observed variables and hidden variables. SSM uses an iterative method, namely Expectation-Maximization, to infer regulatory relationships from microarray datasets. The hidden variables cannot be directly observed from experiments. How to determine the number of hidden variables has a significant impact on the accuracy of network inference. In this study, we used SSM to infer Gene regulatory networks (GRNs) from synthetic time series datasets, investigated …

Place, Purpose, And Practice: A Case Study Examining Rural Teachers’ Sense Of Community And Its Impact In The Classroom, Faith Beyer Hansen

Boise State University Theses and Dissertations

In an era in which education policy directs schools towards economic outcomes and away from local and/or community goals, this research is rooted in the notion that place matters (Howley & Howley, 1995). More specifically, this study examines what impact a rural teacher’s sense of community has on her experiencing both the broader community, the community of her individual classroom, and on her practice.

This collective case study followed six teachers in one rural middle school in the mountain west. Participants were nominated using a Sense of Community Index (SCI-2) and fell into the following categories: teachers with a low, …

Cost-Effective Binomial Sequential Sampling Of Western Bean Cutworm, Striacosta Albicosta (Lepidoptera: Noctuidae), Egg Masses In Corn, S. Paula-Moraes, E. C. Burkness, Thomas E. Hunt, Robert Wright, Gary Hein, W. D. Hutchinson

Department of Entomology: Faculty Publications

Striacosta albicosta (Smith) (Lepidoptera: Noctuidae), is a native pest of dry beans (Phaseolus vulgaris L.) and corn (Zea mays L.). As a result of larval feeding damage on corn ears, S. albicosta has a narrow treatment window; thus, early detection of the pest in the field is essential, and egg mass sampling has become a popular monitoring tool. Three action thresholds for field and sweet corn currently are used by crop consultants, including 4% of plants infested with egg masses on sweet corn in the silking-tasseling stage, 8% of plants infested with egg masses on field corn with …

Happiness And Time Preference: The Effect Of Positive Affect In A Random-Assignment Experiment, John Ifcher, Homa Zarghamee

Economics

We conduct a random-assignment experiment to investigate whether positive affect impacts time preference, where time preference denotes a preference for present over future utility. Our result indicates that, compared to neutral affect, mild positive affect significantly reduces time preference over money. This result is robust to various specification checks, and alternative interpretations of the result are considered. Our result has implications for the effect of happiness on time preference and the role of emotions in economic decision making, in general. Finally, we reconfirm the ubiquity of time preference and start to explore its determinants. (JEL D12, D83, I31)

Hybridizing Jurisdiction, Scott Dodson

Faculty Publications

Federal jurisdiction – the “power” of the court – is seen as something separate and unique. As such, it has a litany of special effects that define jurisdictionality as the antipode of nonjurisdictionality. The resulting conceptualization is that jurisdictionality and nonjurisdictionality occupy mutually exclusive theoretical and doctrinal space. In a recent Article in Stanford Law Review, I refuted this rigid dichotomy of jurisdictionality and nonjurisdictionality by explaining that nonjurisdictional rules can be “hybridized” with any – or even all – of the attributes of jurisdictionality.

This Article drops the other shoe. Jurisdictional rules can be hybridized, too, and in myriad …

Study Of Feature Selection Algorithms For Text-Categorization, Kandarp Dave

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis will discuss feature selection algorithms for text-categorization. Feature selection algorithms are very important, as they can make-or-break a categorization engine. The feature selection algorithms that will be discussed in this thesis are Document Frequency, Information Gain, Chi Squared, Mutual Information, NGL (Ng-Goh-Low) coefficient, and GSS (Galavotti-Sebastiani-Simi) coefficient . The general idea of any feature selection algorithm is to determine importance of words using some measure that can keep informative words, and remove non-informative words, which can then help the text-categorization engine categorize a document, D , into some category, C . These feature selection methods are explained, implemented, …

Human Health And The Environment Can't Wait For Reform: Current Opportunities For The Federal Government And States To Address Chemical Risks Under The Toxic Substances Control Act, Lauren Trevisan

American University Law Review

Expressing its concern about growing rates of cancer and other diseases, coupled with the lack of data about the effect of the thousands of chemicals used in U.S. society, in 1976 Congress enacted the Toxic Substances Control Act (TSCA). Congress intended for TSCA to shed new light on chemical risks and provide the U.S. Environmental Protection Agency (EPA) with a set of tools to address those risks and protect human health and the environment. In the years since TSCA’s passage, the procedural hurdles and the difficult-to-meet legal standards built into the statute, along with a court decision rejecting EPA’s use …

More Than Memories? Schema Transference From Media Characters To Real People, Hilary Ray

Graduate Theses and Dissertations

This study focused on whether personality traits and evaluations of television personalities are used to make inferences about new Social interaction partners. It tested the hypothesis that priming schemas of television personalities will bias inferences made about a stranger. The results were mixed. Participants in the experimental condition made more biased inferences about a stranger than did participants in the control condition. This transference was not influenced by participants' parasociability, and methodological limitations prevented conclusive study of the influence of affective evaluations in this effect. Future studies should attempt to increase methodological control and introduce a diverse set of measures …

Master's Theses

In recent years transportation professionals have shown increasing interest in evacuation planning. With the advances in computing technologies it is possible to simulate urban transportation networks with great detail. These details from the traffic simulation model can be used for devising strategies for evacuation and emergency response in case of a disaster.

This thesis describes the modeling, calibration, and validation of the VISSIM traffic simulation model coded for downtown San Jose. The network is then used to test various evacuation scenarios to assess evacuation strategies that would be effective in case of a human-caused disaster.

The network modeled in the …

Digitally-Controlled Deep Brain Stimulation Lead Implant System, Matthew Joseph Phillips

Master's Theses

Deep brain stimulation, the treatment of disorders by applying electrical stimulation to brain tissue, is a relatively new field of medicine with great potential to provide cures for neurological disorders. It utilizes a system very similar to a cardiac pacemaker and lead to electrically stimulate brain tissue. This electrical stimulation is programmed to disrupt or mask aberrant brain signals while not impeding the normal function of the brain. The advances in implantable pulse generators designed for deep brain stimulation have been remarkable, and the applications for deep brain stimulation continue to grow including multiple sclerosis (Berk, et al. 2002), severe …

Measurement Of Impact Of Banking System Development On Economic Growth In Iraq, Ammar Hamad Khalaf

Journal of Economics and Administrative Sciences

At the heart of every robust economy is a vital banking system. The functional banking system can effectively perform several functions such as mobilizing savings, allocating credit, monitoring managers, transforming risks, and facilitating the financial transactions. This paper aims to measure the impact of banking system development on economic growth in Iraq. Credit to private sector divided by GDP used as a proxy of banking development. Real per capita GDP used as a proxy of economic growth. By using Autoregressive Distributed Lag (ARDL) model, the paper finds that the undeveloped Iraqi banking system could not promote economic growth in the …

Ecology Of Ticks (Acari: Ixodidae) In Shelterbelts Of Southeastern Nebraska, Matthew W. Yans

Department of Entomology: Dissertations, Theses, and Student Research

Shelterbelts in the agricultural landscape provide valuable habitat to a variety of animals that in turn may be hosts to ixodid ticks. The purpose of this study is to determine if shelterbelt associated factors influence tick ecology. In 2010 and 2011, ticks were collected from several shelterbelts in southeast Nebraska in Lancaster and Saunders counties. Four tick species were identified.

Adjacent land use, shelterbelt composition, and time of day were all factors which did not influence the number of questing ticks collected. Differences in relation to aspect and distance from the shelterbelt were significant. The east side had continually higher …

Norms And Survival In The Heat Of War: Normative Versus Instrumental Rationalities And Survival Tactics In The Blockade Of Leningrad, Jeffrey K. Hass

Sociology and Anthropology Faculty Publications

When war challenges civilian survival, what shapes the balance between normative and instrumental rationalities in survival practices? Increasing desperation and uncertainty can lead civilians to focus on their own material interests and to violate norms in the name of survival or gain—to the detriment of the war effort and of other civilians. Do norms, boundaries against transgressions, and considerations of collective interests and identities persist, and, if so, through what mechanisms? Using diaries and recollections from the 872-day Blockade of Leningrad (1941–1944)—an extreme case of wartime desperation—this article examines how three forms of cultural embeddedness shape variation in the strength …

Financial Sector Development And Economic Growth: A Theoretical Exposition, Peter N. Umoh

Economic and Financial Review

The various literature and studies reviewed in this exposition have underscored the positive impacts of a developed financial sector on an economy. Whilst a few studies showed that finance follows growth, the majority opinion is that finance leads growth. Unfortunately, growth has not led to economic development in many developing economies, necessitating intervention by such bodies as the United Nations, International Labour Organization and United Nations Development Programme. Economists are equally concerned about this development and have, therefore, conducted studies to show the relationship between economic growth and poverty alleviation. They generally agreed that growth is good for poverty reduction.

The Millennium Development Goals: What Role For The Financial Sector In Nigeria., J. Aremu

Economic and Financial Review

Explanations from this paper revealed that financial sector development can make an important contribution to economic growth and poverty reduction. This is especially likely to be true in Nigeria, whose financial sectors is still developing, and without which economic development of the country as well as achievement of the MDGs may be constrained, even if other necessary conditions are met. It was discovered that the poor in the country, who are the target for the achievement of the MDGs often do not have access to ongoing, formal financial services, and are forced to rely instead on a narrow range of …
