Impacts Of Queue Jumpers And Transit Signal Priority On Bus Rapid Transit, R.M. Zahid Reza Jan 2012

Impacts Of Queue Jumpers And Transit Signal Priority On Bus Rapid Transit, R.M. Zahid Reza

Electronic Theses and Dissertations 2010 - 2019

Exclusive bus lanes and the Transit Signal Priority are often not effective in saturated peak-traffic conditions. An alternative way of providing priority for transit can be queue jumpers, which allows buses to bypass and then cut out in front of waiting queue by getting an early green signal. Utah Transit authority deployed Bus Rapid Transit system at Salt Lake County, Utah along W 3500 S. This research evaluates the impacts of queue jumpers with TSP on Bus Rapid Transit (BRT) and private vehicular traffic. Four VISSIM models were developed for analysis : Basic scenario, no TSP with queue jumpers, TSP …

Implementation Of An Improved Embedded Sql For Java, Louis M. Bradley Jan 2012

Implementation Of An Improved Embedded Sql For Java, Louis M. Bradley

Electronic Theses and Dissertations 2010 - 2019

The Java Devlopment Environment defines SQLJ as a standard way of embedding the relational database language SQL in the object-oriented programming language Java. Oracle Corporation provides an extension of SQLJ that supports dynamic SQL constructs for the processing of SQL commands that are not completely known at compile time. Unfortunately, these constructs are not sufficient to handle all dynamic situations, so that the programmer has to depend on other SQL embeddings, such as JDBC, in addition to Oracle's SQLJ. In this thesis we implement several extensions to Oracle's SQLJ so that all dynamic situations can be programmed in SQLJ, without …

Inflammatory Response In Stress And The Role Of Autophagy In Breast Cancer, Lillian C. Onwuha-Ekpete Jan 2012

Inflammatory Response In Stress And The Role Of Autophagy In Breast Cancer, Lillian C. Onwuha-Ekpete

Electronic Theses and Dissertations 2010 - 2019

We attempted to understand the molecular regulators that impact inflammation using a rat model of human sensation-seeking/risk-taking trait for drug and stress vulnerability, based on their exploratory behavior displaying high rates (HRs) or low rates of locomotor reactivity (LRs) to environmental stress. We found that HRs have a pro-inflammatory phenotype as indicated by increased protein expression of the inflammatory cytokine TNF-(Sa(B. Furthermore, we found that HRs have a lower gene expression of the glucocorticoid receptor and histone deacetylase 2 which are known to play an immunosuppressive role. Autophagy (macroautophagy) is a homeostatic process needed for cell maintenance, growth and proliferation …

Influence Of The Global Economic Crisis On The Relationship Between Governance And Economic Growth, Bassam A. Albassam Jan 2012

Influence Of The Global Economic Crisis On The Relationship Between Governance And Economic Growth, Bassam A. Albassam

Electronic Theses and Dissertations 2010 - 2019

The current economic crisis has affected all aspects of life, which has resulted in political instability, personal financial troubles, and a growing number of business bankruptcies. While these are serious issues, simply developoing a government policy that injects an economy with money is not an appropriate means to achieve economic recovery and long-term economic development unless combined with an effective and efficient governing system. The present research studies whether the strong relationship between governance and growth exists during economic crises or only during non-crisis periods. The results of the current research show that the global economic crisis has had an …

Internal Waves On A Continental Shelf, Arjun. Jagannathan Jan 2012

Internal Waves On A Continental Shelf, Arjun. Jagannathan

Electronic Theses and Dissertations 2010 - 2019

In this thesis, a 2D CHebyshev spectral domain decomposition method is developed for simulating the generation and propagation of internal waves over a topography. While the problem of stratified flow over topography is by no means a new one, many aspects of internal wave generation and breaking are still poorly understood. This thesis aims to reproduce certain observed features of internal waves by using a Chebyshev collation method in both spatial directions. The numerical model solves the inviscid, incomprehensible, fully non-linear, non-hydrostatic Boussinesq equations in the vorticity-streamfunction formulation. A number of important features of internal waves over topography are captured …

Interpretation Of Forced And Unforced Choice Behavior, Brian. Vail Jan 2012

Interpretation Of Forced And Unforced Choice Behavior, Brian. Vail

Electronic Theses and Dissertations 2010 - 2019

The current study investigated the interpretation of an agent's actions under the influence of external forces. Participants viewed a series of videos of an agent making a varying series of decisions and forced behaviors and were asked to predict future behavior. Firstly, we found evidence that suggests that perceivers make inferences about an agent that once they have shown a preference toward an object, they will persist with those initial desires, despite, external forces leading them to a different object. Secondly, we found evidence that suggests that submitting to a coerced choice will be perceived as reflecting a conflicting combination …

Population Distribution, Habitat Selection, And Life History Of The Slough Crayfish (Procambarus Fallax) In The Ridge-Slough Landscape Of The Central Everglades, Der Heiden Craig Van Jan 2012

Population Distribution, Habitat Selection, And Life History Of The Slough Crayfish (Procambarus Fallax) In The Ridge-Slough Landscape Of The Central Everglades, Der Heiden Craig Van

Electronic Theses and Dissertations 2010 - 2019

Understanding where and why organisms are distributed in the environment are central themes in ecology. Animals live in environments in which they are subject to competing demands, such as the need to forage, to find mates, to reproduce, and to avoid predation. Optimal habitats for these various activities are usually distributed heterogeneously in the landscape and may vary both spatially and temporally, causing animals to adjust their locations in space and time to balance these conflicting demands. In this dissertation, I outline three studies of Procambarus fallax in the ridge-slough landscape of Water conservation Area 3A (WCS-3A). The first section …

Pcaob Inspections And Audit Quality Evidence From Cross-Listed Securities, Errol Gg Stewart Jan 2012

Pcaob Inspections And Audit Quality Evidence From Cross-Listed Securities, Errol Gg Stewart

Electronic Theses and Dissertations 2010 - 2019

In the period leading up to the early 2000s there were a series of large company failures attributed at least in part to audit failures. Consequently, the Sarbanes Oxley Act (SOX) was promulgated in July 2002 to restore confidence in public company financial reporting and the work of auditors. The Public Company Accounting Oversight Board (PCAOB) was established by SOX and appointed as the regulator of the accounting firms that audit the financial statements of public companies. The PCAOB is required to routinely inspect the operations of these accounting firms in an effort to satisfy its mandate to bring about …

Phosphorus Limitation In Reef Macroalgae Of South Florida, Courtney. Kehler Jan 2012

Phosphorus Limitation In Reef Macroalgae Of South Florida, Courtney. Kehler

Electronic Theses and Dissertations 2010 - 2019

Nitrogen (N) has traditionally been regarded as the primary limiting nutrient to algal growth in marine coastal waters, but recent studies suggest that phosphorus (P) can be limiting in carbonate-rich environments. To better understand the importance of P. alkaline phosphatase activity (APA) was measured in reef macroalgae in seven counties of south Florida ; several significant trends emerged : 1) APA decreased geographically from the highest values in Dada>Monroe>Palm Beach>St. Lucie>Broward>Martin>Lee counties 2) APA varied temporally with increasing nutrient-rich runoff in the wet season 3) APA varied due to taxonomic division Phaeophyta>Rhodophyta>Chlorophyta …

Product Placement Within Violent Media, Johanna D. Berger Jan 2012

Product Placement Within Violent Media, Johanna D. Berger

Electronic Theses and Dissertations 2010 - 2019

Despite extensive research into memory and violence, relatively little is known about the relationship between violent media and memory of advertised products. Research has yielded contradictory evidence ; some scholars have found a negative relationship, others a nonexistent one... This research investigated the role of emotion in the relationship between violent media and product placement memory. This study creates insight into inconclusive previous findings by providing evidence that violence influences product memory. Specifically, participants were significantly worse at remembering products placed within violent clips (e.g., free recall, cued recall, recognition. Participants' emotional responses to the violent clips also appeared to …

Psychophysiological Measures Of Aggression And Victimization In Early Adolescence, Christopher D. Aults Jan 2012

Psychophysiological Measures Of Aggression And Victimization In Early Adolescence, Christopher D. Aults

Electronic Theses and Dissertations 2010 - 2019

Many cardiovascular psychophysiological studies have found evidence of lower arousal states in aggressive individuals and hyper-arousal states in individuals exposed to chronic stress. However, most of these studies have relied on clinical diagnoses or self-reports to identify aggressive and victimized individuals. The present study used peer nominations to identify aggressive, victimized, and non-aggressive or victimized adolescents (mean age = 12.09 yrs.) to examine if any psychophysiological differences exist during resting and startle conditions. ANOVAs revealed that high aggressive/low victimized adolescents had a lower resting heart period/rate compared to high victimized/low aggressive adolescents. Further analyses revealed a statistical trend of lower …

Principals' Knowledge Of Special Education Policies And Procedures, Lindsay. Jesteadt Jan 2012

Principals' Knowledge Of Special Education Policies And Procedures, Lindsay. Jesteadt

Electronic Theses and Dissertations 2010 - 2019

Research has shown that most school leaders lack the knowledge necessary to deal with the many different aspects and issues that special education programs encompass. This lack of knowledge ultimately places special education teachers, programs, and students with disabilities at a clear disadvantage. With The No Child Left Behind Act (NCLB) of 2001 and the reauthorization of The Individuals with Disabilities Education Improvement Act (IDEA) in 2004, schools and school leaders are being held accountable for the learning gains of all students, including students with disabilities. This study sought to assess the knowledge of Florida school principals in the area …

Constitutional Gaps In Bankruptcy, S. Todd Brown Jan 2012

Constitutional Gaps In Bankruptcy, S. Todd Brown

Journal Articles

Federal bankruptcy law incorporates a broad range of commercial and related matters that are otherwise left to the States under the Constitution, follows an efficiency-centered process model that may implicate due process, and relies upon a judicial structure that appears to be inconsistent with Article III. In spite of the crushing volume of bankruptcy cases and proceedings each year in which the resolution of one or more of these questions may be relevant, the Supreme Court has had few opportunities to tackle them directly. Indeed, after more than two centuries, the Court has provided precious few insights into the limits …

Preliminary Typology Of Aztec Formal Chipped Stone Tools, Timothy J. Guyah Jan 2012

Preliminary Typology Of Aztec Formal Chipped Stone Tools, Timothy J. Guyah

Electronic Theses and Dissertations 2010 - 2019

This preliminary typology of Aztec formal chipped stone tools was created taking into account the context in which the lithics were recovered, their morphology, and manufacturing processes. The typology defines six categories of stone tools: ornately decorated bifaces (this includes ceremonial lithic artifacts), projectile points, scrapers, perforators, denticulates, and other. The thesis also includes an analysis of 10 previously unanalyzed Aztec lithic assemblages. When taken together the typology and lithic analysis provide a summary description of the Aztec lithic industry.

Reducing Impedance Mismatch In Sql Embeddings For Object-Oriented Programming Languages, Jose Luis Hurtado Jan 2012

Reducing Impedance Mismatch In Sql Embeddings For Object-Oriented Programming Languages, Jose Luis Hurtado

Electronic Theses and Dissertations 2010 - 2019

We survey and compare the different major mechanisms for embedding the relational database language SQL in object-oriented programming languages such as Java and C#, with regard to how much impedance mismatch these embeddings suffer. Here impedance mismatch refers to clarity and performance difficulties that arise because of the nature of the embedding. Because of the central position in the information technology industry of object-oriented programs that access SQL-based relational database systems, reducing impedance mismatch is generally recognized in that industry as an important practical problem. We argue for the suitability of SQL as a database language, and hence for the …

Race And Representation In Friday Night Lights, Keisha. Johnson Jan 2012

Race And Representation In Friday Night Lights, Keisha. Johnson

Electronic Theses and Dissertations 2010 - 2019

This thesis will highlight the significance and representation of race in the film and television show Friday Night Lights. The core claim of my thesis will show that representation of race was different in the film as compared to the television show due to their various settings, one historical (1980s) and the other contemporary (2000s). While both the film and the television show were produced in the 2000s, their use of two different historical periods allows for contrasting representations of race even they both draw from the book Friday Night Lights. The film's representation of race is reflective of its …

Quantifying The Energetic Cost Of Disorientation In Loggerhead (Caretta Caretta) And Green (Chelonia Mydas) Sea Turtle Hatchlings, Sean. Williams

Electronic Theses and Dissertations 2010 - 2019

The photopollution of beaches caused by artificial light sources can interfere with sea turtle hatchlings' ability to orient properly towards the sea. Exhaustion due to extended disorientation crawling may then increase hatchling mortality. This study evaluated the energetic consequences of long-distance crawls in green and loggerhead sea turtle hatchlings. Turtles crawled for 200 m or 500 m on a treadmill, followed by a 30 minute evaluation of swim performance. Metabolic activity was quantified via measures of blood glucose, blood lactate, and oxygen consumption. No significant changes in metabolism resulted from long-distance crawling activity in loggerheads ; however, loggerheads rested for …

Public Speaking As The Last Battlefield, Shaundi C. Newbolt Jan 2012

Public Speaking As The Last Battlefield, Shaundi C. Newbolt

Electronic Theses and Dissertations 2010 - 2019

Communication scholars are in disagreement over the presence of online public speaking courses in higher education. Despite limited research on the Online Public Speaking model, it is quickly replacing the traditional public speaking model in American colleges and universities. This study used Burkean Cluster-Agon Analysis to uncover core concepts from four contemporary public speaking textbooks used in various classroom models (traditional, online and hybrid). Concepts were then compared with traditional core concepts of early speech communication to determine if technology has influenced contemporary core concepts. Results determined that contemporary core concepts from three of the four public speaking textbooks reflected …

Labor Law, New Governance, And The Ghent System, Matthew Dimick Jan 2012

Labor Law, New Governance, And The Ghent System, Matthew Dimick

Journal Articles

The Employee Free Choice Act (EFCA) was the most significant legislation proposed for reforming the National Labor Relations Act (NLRA) in over a generation and the centerpiece of the American labor movement’s revitalization strategy. Yet EFCA hews closely to the particular regulatory model established by the NLRA at the peak of the New Deal, now over seventy-five years ago. Further, recent scholarship suggests that traditional regulatory approaches are giving way to new kinds of governance methods for addressing social problems. Rather than reviving an old regulatory model, should “New Governance” approaches instead be sought for addressing problems in employment representation? …

Religious Violence In Frank Herbert's Dune Series, Kenton Taylor Howard Jan 2012

Religious Violence In Frank Herbert's Dune Series, Kenton Taylor Howard

Electronic Theses and Dissertations 2010 - 2019

This thesis examines the first two novels of Frank Herbert's Dune series, Dune and Dune Messiah, in order to consider these two novels from the framework of postcolonial theory and analyze how religious violence becomes a source of subjugation, military power, and colonialism within the works. The three chapters of this thesis chart the creation of a colonial project through epistemic violence, physical power, and cultural control enabled by religion. This thesis argues that, in the Dune novels, religious violence functions as a colonial project that closely resembles the goals of real-world colonial enterprises, and the failure to manage this …

Revisiting The Methodology And Application Of Value-At-Risk, Kyong. Chung Jan 2012

Revisiting The Methodology And Application Of Value-At-Risk, Kyong. Chung

Electronic Theses and Dissertations 2010 - 2019

The main objective of this thesis is to simulate, evaluate and discuss three standard methodologies of calculating Value-at-Risk (VaR) : Historical simulation, the Variance-covariance method and Monte Carlo simulations. Historical simulation is the most common nonparametric method. The Variance-covariance and Monte Carlo simulations are widely used parametric methods. This thesis defines the three aforementioned VaR methodologies, and uses each to calculate 1-day VaR for a hypothetical portfolio through MATLAB simulations. The evaluation of the results shows that historical simulation yields the most reliable 1-day VaR for the hypothetical portfolio under extreme market conditions. Finally, this paper concludes with a suggestion …
