Effect Of Business Intelligence And It Infrastructure Flexibility On Organizational Agility, Xiaofeng Chen, Keng Siau Dec 2012

Effect Of Business Intelligence And It Infrastructure Flexibility On Organizational Agility, Xiaofeng Chen, Keng Siau

Research Collection School Of Computing and Information Systems

There is a growing use of business intelligence (BI) for better management decisions in different industries. However, empirical studies on BI are still scarce in academic research. This research investigates BI from an organizational agility perspective. Organizational agility is the ability to sense and respond to market opportunities and threats with speed. Drawing on systems theory and literature on organizational agility, business intelligence, and IT infrastructure flexibility, we hypothesize that BI use and IT infrastructure flexibility are two major antecedents to organizational agility. We developed a research model to examine the effect of BI use and IT infrastructure flexibility on …

Community-Based Classification Of Noun Phrases In Twitter, Freddy Chong Tat Chua, William W. Cohen, Justin Betterridge, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Many event monitoring systems rely on counting known keywords in streaming text data to detect sudden spikes in frequency. But the dynamic and conversational nature of Twitter makes it hard to select known keywords for monitoring. Here we consider a method of automatically finding noun phrases (NPs) as keywords for event monitoring in Twitter. Finding NPs has two aspects, identifying the boundaries for the subsequence of words which represent the NP, and classifying the NP to a specific broad category such as politics, sports, etc. To classify an NP, we define the feature vector for the NP using not just …

An Automated Pathological Class Level Annotation System For Volumetric Brain Images, Thien Anh Dinh, Tomi Silander, C. C. Tchoyoson Lim, Tze-Yun Leong Dec 2012

An Automated Pathological Class Level Annotation System For Volumetric Brain Images, Thien Anh Dinh, Tomi Silander, C. C. Tchoyoson Lim, Tze-Yun Leong

Research Collection School Of Computing and Information Systems

We introduce an automated, pathological class level annotation system for medical volumetric brain images. While much of the earlier work has mainly focused on annotating regions of interest in medical images, our system does not require annotated region level training data nor assumes perfect segmentation results for the regions of interest; the time and effort needed for acquiring training data are hence significantly reduced. This capability of handling high-dimensional noisy data, however, poses additional technical challenges, since statistical estimation of models for such data is prone to over-fitting. We propose a framework that combines a regularized logistic regression method and …

Grand Theft Auto Loans: Repossession And Demographic Realities In Title Lending, Nathalie Martin Dec 2012

Grand Theft Auto Loans: Repossession And Demographic Realities In Title Lending, Nathalie Martin

Faculty Scholarship

This Article analyzes empirical data on one of America's fastest growing credit products, the title loan. A title loan is a high-interest, deeply oversecured, consumer loan, in which the consumer uses an unencumbered automobile as collateral for a non-purchase money loan. Title loans are made based solely on equity in a car. If a customer has insufficient income to pay the payments under the loan, typically interest-only payments at 300% per annum or more, the lender repossesses the vehicle, many of which have GPS trackers installed for this purpose. Not surprisingly, the repossession rates for title loans are higher than …

Conservation Genetics Of A Spotted Salamander (Ambystoma Maculatum (Shaw 1802)) Local Population In Southeast Tennessee, Daniel Scott Armstrong Dec 2012

Conservation Genetics Of A Spotted Salamander (Ambystoma Maculatum (Shaw 1802)) Local Population In Southeast Tennessee, Daniel Scott Armstrong

Masters Theses and Doctoral Dissertations

Currently there is a worldwide amphibian decline with numerous causes. Because of this, it is important to understand how genetic variation in local amphibian populations is affected by disturbance. The goal of this study was to assess the genetic impacts of past chemical and ammunition storage and present industrialization on a local population of Ambystoma maculatum (Shaw 1802) using thirteen microsatellite markers. Most loci exhibited no loss of heterozygosity but the low effective population size may indicate vulnerability to future declines. No population substructure or sex-biased dispersal was detected. Possible explanations for the reduction in genetic diversity at four loci …

Call It Courage: The Effects Of Perspective, Humility, Locus Of Control, And Social Desirability On Perceptions Of Accolade Courage In Male Student And Military Populations, Chad Breeden Dec 2012

Call It Courage: The Effects Of Perspective, Humility, Locus Of Control, And Social Desirability On Perceptions Of Accolade Courage In Male Student And Military Populations, Chad Breeden

All Theses

Courage - despite millennia of contemplation - is only now seeing efforts at empirical study and definition. Recent studies have attempted to break down the component parts of courage, but do not address why courage appears to only be bestowed on others and rarely to oneself: a phenomenon known as courage blindness (Biswas-Deiner, 2012). This paper examines how individuals attribute courage to themselves and how they attribute it to others. Male military personnel (n =86) and male college students (n =106) read 14 scenarios of varying courage, rating the courageousness of themselves or another person based on the action. Multiple …

Design And Implementation Of A Genre Hybrid Video Game That Integrates The Curriculum Of An Introductory Programming Course, Cory Buckley Dec 2012

Design And Implementation Of A Genre Hybrid Video Game That Integrates The Curriculum Of An Introductory Programming Course, Cory Buckley

All Theses

Video games have a history of being exploited for education. However, all too fre- quently, the resulting educational video game is either transparent in its hijacking of video game media, or the educational content is not intelligently placed within the context of the game. In this paper we analyze existing educational video games and observe popular commercial video game mechanics to form a more player oriented development mindset. Our approach involves mingling game mechanics that are not commonly used together to create a genre hybrid educational video game with a seamlessly integrated introductory programming curriculum. We use a machine architecture …

Evaluation Of 26al Method As Star Formation Rate Indicator, Manjeet Singh Dec 2012

Evaluation Of 26al Method As Star Formation Rate Indicator, Manjeet Singh

All Theses

The aim of this work is to evaluate the '26Al method' used to determine the Galactic Star Formation Rate (SFR) and compare it to other alternative methods. 26Al is a radioactive isotope produced mainly in massive star winds and in the ensuing core collapse supernova explosion. The radioactive 26Al decays with a life time of 106 years by emitting γ- ray photons in 1.808 MeV band. The 26Al method involves using the Galactic 26Al radioactive flux as a tracer. This approach based on the γ- ray line measurements does not suffer from extinction and small number statistics.

Observers' Judgments Of The Effects Of Glare On Visual Acuity, Ashley Sewall Dec 2012

Observers' Judgments Of The Effects Of Glare On Visual Acuity, Ashley Sewall

All Theses

Traffic collisions and pedestrian fatalities increase significantly when driving at night. There is a need for greater roadway visibility when driving at night and the use of high beam headlights can significantly improve the distance at which drivers recognize objects along the roadway. However, research suggests that drivers underuse their high beams. It is possible that drivers do not use their high beam headlights in an effort to minimize glare to oncoming vehicles. The purposes of this experiment were to extend earlier research indicating that the visually impairing effects of glare may often be exaggerated and to investigate the role …

Determination Of A Higher-Order Elastic Constant Of A Single Filament Of Hextow Im7-12k Carbon Fiber Using Finite Deformations, Luciana Oliveira Dec 2012

Determination Of A Higher-Order Elastic Constant Of A Single Filament Of Hextow Im7-12k Carbon Fiber Using Finite Deformations, Luciana Oliveira

All Theses

The modulus of elasticity of a homogeneous body is the same for all directions. No known crystalline materials have a Young's modulus that is the same in all directions. The linear theory of elasticity states that strain is proportional to stress so that a straight line is obtained in a stress versus strain plot. As long as the forces applied to the body are proportional, the body behaves perfectly elastically, obeying Hooke's law. At high enough strains, however, deviations from Hooke's law will occur. Nonlinear elasticity is generally apparent when large deformations are applied and usually when the sample size …

I Laughed Until I Cried: The Tragicomedy Of Harold Pinter's The Homecoming , Kesha Garner Dec 2012

I Laughed Until I Cried: The Tragicomedy Of Harold Pinter's The Homecoming , Kesha Garner

All Theses

There appears to be a disconnect between the actual events of Harold Pinter's The Homecoming and the scholarly work devoted to the play--while each of the main characters are morally problematic, it is only the play's sole female character, Ruth, whose morality is questioned. This schism in which Ruth is questioned but others are not stems primarily from the time in which most of this criticism occurred: before post-structuralist understandings of gender undermined our presuppositions about the sexes. The Homecoming was written on the cusp of second-wave feminism, the movement focusing mainly on the legal and social equality of women, …

Development Of A Two-Dimensional Model Of A Pneumatic Tire, Timothy Lewis Dec 2012

Development Of A Two-Dimensional Model Of A Pneumatic Tire, Timothy Lewis

All Theses

The pneumatic tire has been studied extensively since its invention in 1888. With the advent of high-powered computers and the use of the finite element method, the understanding of the tire's complex non-linear behavior has grown tremendously. However, one weakness of finite element models is that parameter studies are difficult and time consuming to perform. In contrast, an analytical model can quickly and easily perform extensive parameter studies. To the knowledge of the author, all existing analytical models of the tire make assumptions concerning the tire's behavior and construction that while useful for obtaining some of the first-order characteristics, are …

Examining The Short-Run Price Elasticity Of Gasoline Demand In The United States, Michael Brannan Dec 2012

Examining The Short-Run Price Elasticity Of Gasoline Demand In The United States, Michael Brannan

All Theses

Estimating the consumer demand response to changes in the price of gasoline has important implications regarding fuel tax policies and environmental concerns. There are reasons to believe that the short-run price elasticity of gasoline demand fluctuates due to changing structural and behavioral factors. In this paper I estimate the short-run price elasticity of gasoline demand in two time periods, from 2001 to 2006 and from 2007 to 2010. This study utilizes data at both the national and state levels to produce estimates. The short-run price elasticities range from -0.034 to -0.047 during 2001 to 2006, compared to -0.058 to -0.077 …
