Modeling Considerations For Vadose Zone Soil Moisture Dynamics, Jing Zhang

USF Tampa Graduate Theses and Dissertations

Reproducing moisture retention behavior of the upper and lower vadose zone in shallow water table settings provides unique challenges for integrated (combined surface and groundwater) hydrological models. Field studies indicate that moisture retention in shallow water table settings is highly variably affected by antecedent state and air entrapment. The theory and vertical behavior of a recently developed integrated surface and groundwater model (IHM) is examined through comparisons to collected field data in West-Central Florida. The objectives of this study were to (1) Identify important considerations and behavior of the vadose zone for reproducing runoff, ET and recharge in shallow water …

Using Machine Learning Techniques To Create Ai Controlled Players For Video Games, Bhuman Soni

Theses : Honours

This study aims to achieve higher replay and entertainment value in a game through human-like AI behaviour in computer controlled characters called bats. In order to achieve that, an artificial intelligence system capable of learning from observation of human player play was developed. The artificial intelligence system makes use of machine learning capabilities to control the state change mechanism of the bot. The implemented system was tested by an audience of gamers and compared against bats controlled by static scripts. The data collected was focused on qualitative aspects of replay and entertainment value of the game and subjected to quantitative …

A Collective Action Perspective On Ceiling Preemption By Federal Environmental Regulation: The Case Of Global Climate Change, Robert L. Glicksman, Richard E. Levy

GW Law Faculty Publications & Other Works

In an era of regulatory skepticism, proponents of regulation in general and environmental regulation in particular face a number of new political and legal hurdles, particularly at the federal level. Frustrated with federal inaction or weak federal regulation, it is increasingly common for states and local governments to adopt environmental laws that seek to provide greater environmental protection. The critical question is when federal environmental law provides a ceiling, preempting such state regulatory programs. In this article, which is part of a forthcoming symposium on federal preemption in the Northwestern Law Review, Professors Glicksman and Levy develop a framework for …

The Comparative Effectiveness Of Government Interventions On Environmental Performance In The Chemical Industry, Robert L. Glicksman, Dietrich Earnhart

GW Law Faculty Publications & Other Works

Effective enforcement is crucial to achieving the objectives of the federal environmental statutes. The federal Environmental Protection Agency (EPA) has recognized the importance of effective enforcement, calling it a critical aspect of environmental governance and committing itself to the maintenance of a "credible deterrent" to regulatory violations. Despite the central role of enforcement to achievement of environmental statutory goals, relatively little is known about why regulated entities either do or do not comply. In particular, empirical studies of environmental enforcement are not plentiful, in part because comprehensive data on compliance and enforcement have been difficult to obtain. Although EPA and …

A Jurisprudence Of Ideology, Robert L. Glicksman, James May

GW Law Faculty Publications & Other Works

Chief Justice Rehnquist figures prominently in recent historic environmental case law addressed by the Supreme Court. Although generally critical of federal environmental laws, the skepticism stemmed from an interest in the protection of state rights and protection of private property rights rather than a general challenge to federal regulation. His jurisprudence reflects three “guideposts” to consider environmental concerns: limiting the scope of federal power, protecting state sovereignty from encroachment by the federal government, and protecting the rights of private property owners against intrusions resulting from regulation by government. In limiting the scope of federal power, Rehnquist specifically supported limitations on …

Conflicts Of Interest And Corporate Governance Failures At Universal Banks During The Stock Market Boom Of The 1990s: The Cases Of Enron And Worldcom, Arthur E. Wilmarth Jr.

GW Law Faculty Publications & Other Works

The re-entry of commercial banks into the securities business transformed U.S. financial markets during the 1990s. The Gramm-Leach-Bliley Act of 1999 (GLBA) removed most of the legal barriers that had separated commercial and investment banking since 1933. GLBA allows commercial banks to become universal banks by affiliating with securities firms and insurance companies. In large part, GLBA ratified the securities underwriting powers that commercial banks gained during the 1990s, based on a series of orders issued by federal regulators and federal courts.

By 2000, the top ten global underwriters of securities included three U.S. banks, three foreign banks, and four …

Realized Daily Variance Of S&P 500 Cash Index: A Revaluation Of Stylized Facts, Shirley Huang, Qianqiu Liu, Jun Yu

Research Collection School Of Economics

In this paper the realized daily variance is obtained from intraday transaction prices of the S&P 500 cash index over the period from January 1993 to December 2004. When constructing realized daily variance, market microstructure noise is taken into account using a technique proposed by Zhang, Mykland and Ait-Sahalia (2005). The time series properties of realized daily variance are compared with those of variance estimates obtained from parametric GARCH and stochastic volatility models. Unconditional and dynamic properties concerning the realized daily variance are examined, the relationship between realized variance and returns is investigated, and the stylized facts concerning realized daily …

Features Of Optimally Motivating College Classrooms: Perspectives Of Preservice Teachers, Donna S. Bogart

Seton Hall University Dissertations and Theses (ETDs)

The primary objective of this mixed methods study was to explore the parameters of college students' perspectives on classroom learning environments. Specifically, the investigation sought to identify and describe the relevant features of the college classroom context that undergraduate students distinguished as promoting and supporting academic motivation at one four-year postsecondary institution. Secondarily, the study sought to examine the extent to which there was an association between the achievement goals students endorsed and their perspectives concerning the motivating features of the classroom learning environment. The nonprobability purposeful sample of undergraduate students consisted of 122 preservice teachers who were attending a …

Brass: A Queueing Manager For Warrick, Frank Mccown, Amine Benjelloun, Michael L. Nelson

Computer Science Faculty Publications

When an individual loses their website and a backup can-not be found, they can download and run Warrick, a web-repository crawler which will recover their lost website by crawling the holdings of the Internet Archive and several search engine caches. Running Warrick locally requires some technical know-how, so we have created an on-line queueing system called Brass which simplifies the task of recovering lost websites. We discuss the technical aspects of recon-structing websites and the implementation of Brass. Our newly developed system allows anyone to recover a lost web-site with a few mouse clicks and allows us to track which …

Optimal Layout Of Multicast Groups Using Network Embedded Multicast Security In Ad Hoc Sensor Networks, Richard R. Brooks, Brijesh Pillai, Michele C. Weigle, Matthew Pirretti

Computer Science Faculty Publications

This paper considers the security of sensor network applications. Our approach creates multicast regions that use symmetric key cryptography for communications. Each multicast region contains a single keyserver that is used to perform key management and maintain the integrity of a multicast region. Communications between two multicast regions is performed by nodes that belong to both regions. To ease the network management burden, it is desirable for the networks to self-organize into regions and dynamically select their keyservers. This paper shows how to determine the number of keyservers (k) to use and the size in the number of hops (h) …

We discuss the objectives that guided the development of the second version of iSTART toward the goals of increased efficiency …

How Much Preservation Do I Get If I Do Absolutely Nothing? Using The Web Infrastructure For Digital Preservation, Martin Klein, Frank Mccown, Joan A. Smith, Michael Nelson

Computer Science Faculty Publications

To date, most of the focus regarding digital preservation has been on removing copies of the resources to be preserved from the “living web” and placing them in an archive for controlled curation. Once inside an archive, the resources are subject to careful processes of refreshing (making additional copies to new media) and migrating (conversion to new formats and applications). For small numbers of resources of known value, this is a practical and worthwhile approach to digital preservation. However, due to the infrastructure costs (storage, networks, machines) and more importantly the human management costs, this approach is unsuitable for web …

Crate: A Simple Model For Self-Describing Web Resources, Joan A. Smith, Michael L. Nelson

Computer Science Faculty Publications

If not for the Internet Archive’s efforts to store periodic snapshots of the web, many sites would not have any preservation prospects at all. The barrier to entry is too high for everyday web sites, which may have skilled webmasters managing them, but which lack skilled archivists to preserve them. Digital preservation is not easy. One problem is the complexity of preservation models, which have specific meta-data and structural requirements. Another problem is the time and effort it takes to properly prepare digital resources for preservation in the chosen model. In this paper, we propose a simple preservation model called …

A Comparison Of Edge Detection Methods For Segmentation Of Skin Lesions In Mobile-Phone-Quality Images, Khanh Linh Hua

Theses : Honours

The world is faced with a rapidly increasing number of skin cancers every year. Melanoma is the most deadly type of skin cancer though it can be treated if it has been detected at an early stage. However, there is a shortage of dermatologists in rural areas. The increasing number of camera phones, together with improved coverage in rural areas gives some potential for tele-dermatology, whereby people with no local access to a dermatologist can send images of suspicious skin lesions to an expert for assessment. Merely relaying images to a human expert solves only part of the problem, there …

Redefining Electro-Acoustic: Applying Techniques From Electronic Music To The Composition Of Pivot, An Acoustic Work For Percussion Quartet, Joe Stawarz

Theses : Honours

There are a number of characteristics that distinguish acoustic and electronic music. The most apparent difference is the nature of their sound sources, but there is also substantial variation in the compositional process and in the techniques available to composers of each medium. The history electronic music extends from two traditions: Western Ali Music and popular music. During the 20th Century, composers and popular musicians alike took advantage of the many advances in electronic equipment technology to create new styles of music. The development of electronic instruments and recording equipment offered new sounds and provided new methods for the creation …

A Sense Of Place: An Analysis Of The Role Of Environmental Factors In Presidential Speeches, Timothy Michael Mccue

Honors Program Theses

My research will address some of the unspoken communication that happens when presidents give speeches. In particular I will be addressing environmental factors encountered when presidents give speeches. I have identified a few components that are most important to the environment when a president gives a speech. First I will look at the topic of the speech and the peripheral factors that influence what a president talks about in public. I will only be looking at topic and some of the factors such as timing and other political climate factors that influence topic selection rather than what the president says …

The Equator Principles: The Private Financial Sector's Attempt At Environmental Responsibility, Andrew Hardenbrook

Vanderbilt Journal of Transnational Law

The Equator Principles are a set of voluntary environmental guidelines created to manage environmental degradation that results from large-scale developmental projects in the Third World. On June 4, 2003, ten private financial institutions adopted these guidelines, and by the end of 2006 this number had grown to forty. Moreover, in June 2006 the Principles were revised, raising the level of scrutiny for companies that adhere to these guidelines.

At first blush, the adoption of the Equator Principles by private financial institutions appears to be a substantial step toward implementing environmental standards in developing countries that lack adequate regulations. However, three …

Tracking Of Carbon Monoxide Poisoning Using Michigan Emergency Department And Hospital Records, Noreen Hughes, Kenneth D. Rosenman, Joseph Gardiner, Corinne Miller, Mary Jo Reilly

Michigan Journal of Public Health

Objectives: Among all deaths due to poisonings, carbon monoxide (CO) is the leading cause. Development of a surveillance system to track CO poisoning is a recommended public health activity. Initial steps to develop such a system are discussed. Methods: Michigan hospitals provided face sheets and discharge summaries of hospitalized and emergency department visits for CO poisonings. Reports were divided into three categories; intentional poisoning, non-work-related poisoning, and work related poisoning. The characteristics of the three groups, including demographics, sources of exposure, carboxyhemoglobin levels, and time of year were described. Results: There were 847 cases of CO poisoning reported. Another 312 …

Days Without Immigrants: Analysis And Implications Of The Treatment Of Immigration Rallies Under The National Labor Relations Act, Michael C. Duff

All Faculty Scholarship

The massive immigration rallies of early 2006 were prompted by anticipated congressional action classifying all unauthorized workers as felons subject to immediate deportation. While a product of federal immigration policy, the rallies implicate federal labor law because they could be characterized as concerted employee action resulting in a series of work stoppages.

Some employees were discharged for missing work to attend the rallies, so an initial question is whether participation in the rallies is protected activity under the National Labor Relations Act. But even assuming the rallies were attended by unauthorized workers, those workers are undeniably employees within the meaning …

The New Commerce Clause Doctrine In Game Theoretical Perspective, Maxwell L. Stearns

Vanderbilt Law Review

The Roberts Court emerges at a critical juncture in the development of Commerce Clause doctrine. While the Commerce Clause doctrine implicates federalism and separation of powers, concerns rooted in the earliest part of our constitutional history, the arrival of a new Court presents an ideal opportunity to critically assess existing doctrines and to develop new analytical paradigms. An analysis of Commerce Clause doctrine reveals that while the Rehnquist Court successfully imposed substantive limits on the scope of this important source of congressional power for the first time in sixty years, that Court was far less successful in developing a coherent …

First Amendment Protection For The Publication Of Private Information, Jared Lenow

Vanderbilt Law Review

Over one hundred years ago, Samuel Warren and Louis Brandeis wrote, "Of the desirability-indeed of the necessity-of some protection [of the right of privacy], there can, it is believed, be no doubt. The press is overstepping in every direction the obvious bounds of propriety and decency." This observation rings even more true today than it did when it was made in 1890. In the past hundred years, members of the media have drastically revised the unwritten rules regarding what topics are fair game. While media outlets uniformly declined to publish photographs of Franklin Delano Roosevelt in a wheelchair while he …
