Art Speaks : Enhancing K-12 Curriculum Through Multicultural Community Public Art, Julie Mejia

Capstone Projects and Master's Theses

Public art is more than outdoor art. It has the potential of being an educational tool. Multicultural community public art can be integrated into core subjects, enhancing students’ learning through both critical thinking and multiculturalism. For this reason, it can be a great asset in the K-12 educational system. Furthermore, it is a way to elevate the status of art in K-12 education, granting it the importance it deserves. This research examines how multicultural community public art can be incorporated into the K-12 curriculum by analyzing literature and conducting interviews.

The National Council Of Teachers Of English And Federal Education Policy, 1958-1966, Curtis Mason

Dissertations

Following the launching of Sputnik in 1957, Congress passed the National Defense Education Act of 1958 that primarily funded research for the teaching of science, foreign language, and math. English was omitted, but in 1961, due to persuading from the National Council of Teachers of English (NCTE), Congress funded a program that established institutes and centers for research for the teaching of English.

In my research I argue that in order to secure federal funding, the NCTE altered its formal mission to accommodate popular educational rhetoric. Ironically, after achieving federal funding for curricula research one outcome was a recommendation for …

Intelligent Buildings: An Investigation Into Current And Emerging Security Vulnerabilities In Automated Building Systems Using An Applied Defeat Methodology, David J. Brooks

Australian Security and Intelligence Conference

Intelligent Buildings (IB) have become increasing popular during the past decade, driven through the need to reduce energy, have more reactive and safer buildings, and increase productivity. IB integrate many systems that were in the past isolated from each other, including fire and life safety, HVAC, lighting, security, etc. Facilities contain commercial-in-confidence material and other valued assets; however, IB are integrated through open and common data communication protocols and hardware, leaving facilities exposed to external and internal threats. The study presents an investigation into IB, based on a defeat evaluation methdology. IB vulnerabilities considered two areas, namely physical and software …

Intelligence Analysis And Threat Assessment: Towards A More Comprehensive Model Of Threat, Charles Vandepeer

Australian Security and Intelligence Conference

A central focus of intelligence is the identification, analysis and assessment of threat. However, as acknowledged by intelligence practitioners, threat assessment lags behind the related field of risk assessment. This paper highlights how definitions of threat currently favoured by intelligence agencies are primarily based on threatening entities alone. Consequently, assessments of threat are almost singularly concerned with understanding an identified enemy’s intentions and capabilities. This ‘enemy-centric’ approach to intelligence analysis has recently come in for criticism. In particular, the shortcomings of the current approach become apparent where the focus of intelligence analysis is on threats from difficult-to-identify sub-state or non-state …

Mathematics, Physics, and Computer Science Faculty Articles and Research

High aerosol loading over the northern Indian subcontinent can result in poor air quality leading to human health consequences and climate perturbations. The international 2008 TIGERZ experiment intensive operational period (IOP) was conducted in the Indo-Gangetic Plain (IGP) around the industrial city of Kanpur (26.51 degrees N, 80.23 degrees E), India, during the premonsoon (April-June). Aerosol Robotic Network (AERONET) Sun photometers performed frequent measurements of aerosol properties at temporary sites distributed within an area covering similar to 50 km(2) around Kanpur to characterize pollution and dust in a region where complex aerosol mixtures and semi-bright surface effects complicate satellite retrieval …

Identifying Factors That Increase The Likelihood For Alcohol-Induced Blackouts In The Prepartying Context, Joseph W. Labrie, Justin F. Hummer, Shannon Kenney, Andrew Lac, Eric Pedersen

Heads Up!

The present study examined risk factors related to “blacking out” (e.g., temporary periods of memory loss during drinking) during preparty drinking events (i.e., pregaming, predrinking). Participants were students from two universities on the West Coast who reported past month prepartying (N = 2,546) in online surveys administered in the fall of 2008. Among these students, 25% (n = 636) reported blacking out during at least one occasion in which they prepartied in the past month. A logistic regression model underscored that Greek student affiliation, family history of alcohol abuse, frequency of prepartying, and both playing drinking games and …

Robustness, Weak Stability, And Stability In Distribution Of Adaptive Filteringalgorithms Under Model Mismatch, Ben G. Fitzpatrick, G. Yin, Le Yi Wang

Mathematics, Statistics and Data Science Faculty Works

This work is concerned with robustness, convergence, and stability of adaptive filtering (AF) type algorithms in the presence of model mismatch. The algorithms under consideration are recursive and have inherent multiscale structure. They can be considered as dynamic systems, in which the `state' changes much more slowly than the perturbing noise. Beyond the existing results on adaptive algorithms, model mismatch significantly affects convergence properties of AF algorithms, raising issues of algorithm robustness. Weak convergence and weak stability (i.e., recurrence) under model mismatch are derived. Based on the limiting stochastic differential equations of suitably scaled iterates, stability in distribution is established. …

Heavy Episodic Drinking On College Campuses: Does Changing The Legal Drinking Age Make A Difference?, Jawaid W. Rasul, Robert G. Rommel, Geoffrey M. Jacquez, Ben G. Fitzpatrick, Azmy S. Ackleh, Neal Simonsen, Richard Scribner

Mathematics, Statistics and Data Science Faculty Works

This article extends the compartmental model previously developed by Scribner et al. in the context of college drinking to a mathematical model of the consequences of lowering the legal drinking age. Method: Using data available from 32 U.S. campuses, the analyses separate underage and legal age drinking groups into an eight-compartment model with different alcohol availability (wetness) for the underage and legal age groups. The model evaluates the likelihood that underage students will incorrectly perceive normative drinking levels to be higher than they actually are (i.e., misperception) and adjust their drinking accordingly by varying the interaction between underage students in …

Finitely 1-Convex F-Rings, Suzanne Larson

Mathematics, Statistics and Data Science Faculty Works

This paper investigates f-rings that can be constructed in a finite number of steps where every step consists of taking the fibre product of two f-rings, both being either a 1-convex f-ring or a fibre product obtained in an earlier step of the construction. These are the f-rings that satisfy the algebraic property that rings of continuous functions possess when the underlying topological space is finitely an F-space (i.e. has a Stone-čech compactification that is a finite union of compact F-spaces). These f-rings are shown to be SV f-rings with bounded inversion and finite rank and, when constructed from semisimple …

The Chemistry Of Atmosphere-Forest Exchange (Cafe) Model-Part 2: Application To Bearpex-2007 Observations, Nicole C. Bouvier-Brown

Chemistry and Biochemistry Faculty Works

In a companion paper, we introduced the Chemistry of Atmosphere-Forest Exchange (CAFE) model, a vertically-resolved 1-D chemical transport model designed to probe the details of near-surface reactive gas exchange. Here, we apply CAFE to noontime observations from the 2007 Biosphere Effects on Aerosols and Photochemistry Experiment (BEARPEX-2007). In this work we evaluate the CAFE modeling approach, demonstrate the significance of in-canopy chemistry for forest-atmosphere exchange and identify key shortcomings in the current understanding of intra-canopy processes.

CAFE generally reproduces BEARPEX-2007 observations but requires an enhanced radical recycling mechanism to overcome a factor of 6 underestimate of hydroxyl (OH) concentrations observed …

Calibration Of The Atlas Intermediate Tile Calorimeter, Heather Brianna Brown

Physics Theses - Archive

The Large Hadron Collider (LHC) at CERN near Geneva, Switzerland is the world's largest particle collider. UTA contributes to the ATLAS detector at the LHC. There are many detection systems within ATLAS, and the hadronic calorimeter (TileCal) is the main interest of the HEP group at UTA. A piece of the TileCal was constructed at UTA and is called the Intermediate Tile Calorimeter (ITC).The ITC is installed in a service region of the detector and the ITC behave differently from other TileCal cells. Due to a different geometry, the ITC cells require special attention and a different method of calibration. …

On The Electronic And Geometric Structure Properties Of Silicon-Germanium Nanoclusters: A Hybrid Density Functional Theoretic Study, Sarah Elizabeth Duesman

Physics Theses - Archive

Hybrid density functional theory has been used to study the electronic and geometric structure properties of silicon-germanium nanoclusters containing up to eight atoms. The hybrid functional used is Becke's three-parameter exchange functional with the exchange-correlation functional of Lee, Yang, and Parr (B3LYP). A large 6-311G(3df,3pd) basis set as implemented in the suite of software Gaussian 03/09 has been used for accurate determinations of all properties of the SimGen (m + n [lesser or equal to] 8) nanoclusters. For each cluster, various different isomers have been studied to arrive at a global minimum energy structure, and for each of these isomers …

Measurement Of Single Diffractive Differential Cross Section (Dσ/(D|T|)) At √(S ) = 1.96 Tev Using The D0 Forward Proton Detectors, Arnab Kumar Pal

Physics Dissertations - Archive

The analysis described in this dissertation uses the Forward Proton Detectors (FPD) installed at the D0 detector in the Tevatron collider at Fermilab to measure the single diffractive differential cross section (d&sigma/(d|t|)) at sqrt(s ) = 1.96 TeV center of mass energy. The single diffractive events are selected using the D0 central detector and the FPD system and |t| of the forward proton are measured using the FPD system. The analysis presents the measurement of the differential cross section of the single diffractive events as a function of |t| in the range 0.2 < |t| < 1.3 GeV2. The differential cross section measurement is within the theoretical and experimental expectations. The total single diffractive cross section (&sigma_sd ) in the region 0.0 < |t| < 1.3 GeV2 is found to be 9.682 ± 0.048(stat.) ± 1.219(syst.) mb.

Relaxations Of L(1, 1)-Labeling For The Broadcast Scheduling Problem, Shaun N. Joseph

Open Access Dissertations

The broadcast scheduling problem asks how an arbitrary network of broadcast transceivers operating on a shared medium may share the medium in such a way that communication over the entire network is possible. In the case where transmissions are explicitly scheduled, as opposed to be determined by contention, the problem is naturally modeled as a graph coloring problem. The canonical model is the L(1, 1)-labeling, also known as the distance-2 coloring, coloring of the graph square, or strict schedule. This coloring is, however, difficult to obtain even sub-optimally and typically uses many colors, which corresponds to an undesirable over-division …

A Neural Network Approach To Estimating The Allowance For Bad Debt, Donald Joyner

Theses and Dissertations

The granting of credit is a necessary risk of doing business. If companies only accepted cash, sales would be negatively impacted. In a perfect world, all consumers would pay their bills when they become due. However, the fact is that some consumers do default on debt. Companies are willing to accept default risk because the value of defaults does not exceed the value of the additional sales generated. This creates an issue in regards to the valuation of uncollectible accounts. In order for a company to disclose the true value of its accounts receivable, it must establish an allowance for …

Global Change Reactive Background Subtraction, Edwin Premkumar Sathiyamoorthy

University of Kentucky Master's Theses

Background subtraction is the technique of segmenting moving foreground objects from stationary or dynamic background scenes. Background subtraction is a critical step in many computer vision applications including video surveillance, tracking, gesture recognition etc. This thesis addresses the challenges associated with the background subtraction systems due to the sudden illumination changes happening in an indoor environment. Most of the existing techniques adapt to gradual illumination changes, but fail to cope with the sudden illumination changes. Here, we introduce a Global change reactive background subtraction to model these changes as a regression function of spatial image coordinates. The regression model is …

A Simultaneous Random Walk Game, Jorge Bañuelos

Mathematics, Statistics, and Computer Science Honors Projects

Two tokens are placed on vertices of a graph. At each time step, one token is chosen and is moved to a random neighboring point. In previous work, Tetali and Winkler studied the Angel strategy for bringing the tokens together as quickly as possible (on average), and the Demon strategy for delaying their collision as long as possible (on average). We build on these results by studying a game version of this process.

In our game, two players take turns choosing the token to move. The Angel player hopes to bring the tokens together while the Demon player tries to …

Interoperability Between Awsome And Other Tools Using Model Driven Architecture, Chitra Srinivasan

Browse all Theses and Dissertations

AFIT Wide Spectrum Object Modeling Environment (AWSOME) is built on an Abstract Syntax Tree (AST) which is the meta-model of AWSOME. Transformations happen internally in AWSOME to transform anything in abstract to concrete. Earlier efforts in AWSOME were focused on developing tools to work on the AST. The goal of this thesis is to make AWSOME interoperable with other available tools. To achieve this goal, the Model Driven Architecture (MDA) concept is used. MDA is a framework aimed at portability, interoperability and reusability among different tools. Among many tools that use MDA context, EclipseUML 2008 and Dresden OCL Toolkit were …

Quantitative Computed-Tomography Based Bone-Strength Indicators For The Identification Of Low Bone-Strength Individuals In A Clinical Environment, Bino Abel Varghese

Browse all Theses and Dissertations

The aim of the current study was to develop quantitative computed-tomography (QCT)-based bone-strength indicators that highly correlate with finite-element (FE)-based strength. We perform a combined numerical-experimental study, comparing FE-predicted surface strains with strain gauge measurements, to validate the FE models of 36 long bones (humerus, radius, femur and tibia) under three-point bending and torsion. The FE models were constructed from trans-axial volumetric CT scans, and the segmented bone images were corrected for partial-volume effects. The material properties (Young's modulus for cortex, density-modulus relationship for trabecular bone and Poisson's ratio) were calibrated by minimizing the error between experiments and simulations among …

Exploring The Potential For Independent Control With The Nia/Brainfingers System - Is Independent Control Of Glance, Muscle, Alpha And Beta Waves Possible?, Jehangir Cooper

Browse all Theses and Dissertations

BCI (Brain-Computer-Interface) devices on the market today, such as the NIA, have the capability to assign computer commands to specific channels (e.g., EMG, EOG, Alpha, and Beta) associated with different methods of control. However, the utility of this capability is dependent on the ability of users to selectively/independently control the specific channels. The NIA system was evaluated to determine if independent control of its channels is possible. Two users with varying levels of experience were used in this study. The users played pong using each of the channels to control the pong paddle, while the data on the activation levels …

Quantum Chemical Analysis Of The Pka's Of Alcohols And A Cellular Automata Model For The Distribution Of Gases In The Earth's Atmosphere, Edur Basha Boyinipalli

Browse all Theses and Dissertations

Alcohols play important roles in many chemical and biological processes, and their acid/base behaviors are often important for these roles. In this study we ask the question, "Can the electronic properties of these compounds offer clues to the compounds' acid/base behaviors?" The study considers whether selected quantum chemical properties can be used to find correlations with the experimental pKa's of the alcohols (aliphatic and aromatic). Calculations were carried out for these alcohols using the semi-empirical RM1 method and the more advanced density functional theory (DFT) B3LYP/6-31+G* method. Significant correlations were found for several quantum chemical descriptors. It was also found …

Measuring Uncertainty Of Protein Secondary Structure, Alan Eugene Herner

Browse all Theses and Dissertations

This dissertation develops and demonstrates a method to measure the uncertainty of secondary structure of protein sequences using Shannon's information theory. This method is applied to a newly developed large dataset of chameleon sequences and to several protein hinges culled from the Hinge Atlas. The uncertainty of the central residue in each tripeptide is computed for each amino acid in a sequence using Cuff and Barton's CB513 as the reference set. It is shown that while secondary structure uncertainty is relatively high in chameleon regions [avg = 1.27 bits] it is relatively low in the regions 1-7 residues nearest a …
