Spectrum Reallocation And The National Broadband Plan, Jeffrey A. Eisenach Dec 2011

Spectrum Reallocation And The National Broadband Plan, Jeffrey A. Eisenach

Federal Communications Law Journal

Of the several significant changes in United States telecommunications policy proposed by the National Broadband Plan, none are more substantial than its proposals for spectrum policy. In particular, the Plan proposes to reallocate 500 MHz of spectrum from broadcast television, mobile satellite, government and other current uses to "mobile broadband" through the use of innovative "incentive auctions" and other voluntary, market-oriented mechanisms. The Plan's spectrum proposals have the potential to be a major step forward in the decades-long, bipartisan effort to replace "command-and-control" spectrum allocation with a more flexible, dynamic and market-oriented approach. Considerable work remains to be done, however, …

Escape Rates For Coupled Particles In A Stochastic Environment, Gregory Slusarczyk Dec 2011

Escape Rates For Coupled Particles In A Stochastic Environment, Gregory Slusarczyk

Theses, Dissertations and Culminating Projects

A particle placed in a deterministic, overdamped potential well will move towards an attractor located at the bottom of the well. Once the particle reaches the attractor, it remains there forever since no other forces are acting on the particle. However, if weak stochasticity is introduced, the particle will fluctuate around the attractor. As a rare event, the noise can organize itself in such a way that a large fluctuation is created that causes the particle to escape from the basin of attraction. The escape rates/escape times can be found both analytically and numerically. Furthermore, it is possible to predict …

Integration Versus Apartheid In Post-Roman Britain: A Response To Thomas Et Al. (2008), John E. Pattison Dec 2011

Integration Versus Apartheid In Post-Roman Britain: A Response To Thomas Et Al. (2008), John E. Pattison

Human Biology Open Access Pre-Prints

The genetic surveys of the population of Britain conducted by Weale et al. and Capelli et al. produced estimates of the Germani immigration into Britain during the early Anglo-Saxon period, c.430-c.730. These estimates are considerably higher than the estimates of archaeologists. A possible explanation suggested that an apartheid-like social system existed in the early Anglo-Saxon kingdoms resulting in the Germani breeding more quickly than the Britons. Thomas et al. attempted to model this suggestion and showed that it was a possible explanation if all Anglo-Saxon kingdoms had such a system for up to 400 yrs. I noted that their explanation …


Factors Determining Media Coverage Of Meat And Poultry Recalls: Evidence From The Ap Newswire, Thais Fregonesi Carvalho Dec 2011

Factors Determining Media Coverage Of Meat And Poultry Recalls: Evidence From The Ap Newswire, Thais Fregonesi Carvalho

Graduate Theses and Dissertations

Food safety is an important public health issue. Product recalls are an important part of the overall food safety system and occur when potentially unsafe products enter the marketplace. However, it is important that information about the recall ultimately reaches the public. This research assesses the publicity that recalls receive by the popular media. The focus is specifically on recalls of meat and poultry products. Publicity is measured by coverage in the AP Newswire. Data were gathered from the United States Department of Agriculture's Food Safety and Inspection Service (FSIS) and cover meat and poultry recalls from 1982 to 2009. …

Career Changers As First-Year Teachers In Rural Schools, Sara Winstead Fry, Holly Anderson Dec 2011

Career Changers As First-Year Teachers In Rural Schools, Sara Winstead Fry, Holly Anderson

Curriculum, Instruction, and Foundational Studies Faculty Publications and Presentations

The challenges novice teachers face as they adjust to inservice teaching are well documented. However, relatively little attention has been given to beginning teachers in rural schools who have had previous careers in other professions. We used qualitative methods to examine the professional experiences and perceptions of four career-changing first-year teachers in rural schools, seeking to identify significant issues in their professional developmental processes. Three primary themes emerged: evidence of effectiveness as teachers; mentoring career changers, and; adjustment to rural school and community. We conclude with implications and recommendations for educators working to support this unique population of educators in …


Comparing The Understandability Of Alternative Data Warehouse Schemas: An Empirical Study, David Schuff, Karen Corral, Ozgur Turetken Dec 2011

Comparing The Understandability Of Alternative Data Warehouse Schemas: An Empirical Study, David Schuff, Karen Corral, Ozgur Turetken

IT and Supply Chain Management Faculty Publications and Presentations

An easily understood data warehouse model enables users to better identify and retrieve its data. It also makes it easier for users to suggest changes to its structure and content. Through an exploratory, empirical study, we compared the understandability of the star and traditional relational schemas. The results of our experiment contradict previous findings and show schema type did not lead to significant performance differences for a content identification task. Further, the relational schema actually led to slightly better results for a schema augmentation task. We discuss the implications of these findings for data warehouse design and future research.

Cellular Poly(C) Binding Proteins 1 And 2 Interact With Porcine Reproductive And Respiratory Syndrome Virus Nonstructural Protein 1Β And Support Viral Replication, Lalit Beura, Phat X. Dinh, Fernando A. Osorio, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

Porcine reproductive and respiratory syndrome virus (PRRSV) infection of swine results in substantial economic losses to the swine industry worldwide. Identification of cellular factors involved in PRRSV life cycle not only will enable a better understanding of virus biology but also has the potential for the development of antiviral therapeutics. The PRRSV nonstructural protein 1 (nsp1) has been shown to be involved in at least two important functions in the infected hosts: (i) mediation of viral subgenomic (sg) mRNA transcription and (ii) suppression of the host’s innate immune response mechanisms. To further our understanding of the role of the viral …


Campus Citizenship And Associational Freedom: An Aristolelian Take On The Nondiscrimination Puzzle, Chapin Cimino Dec 2011

Campus Citizenship And Associational Freedom: An Aristolelian Take On The Nondiscrimination Puzzle, Chapin Cimino

William & Mary Bill of Rights Journal

Student expressive association on campus is a thorny thicket. Student affinity groups often choose to organize around a shared principle or characteristic of the groups’ members, which, by definition, makes those students different in some way from their peers. In order to preserve the group’s sense of uniqueness, these groups often then wish to control their own membership and voting policies. They feel, in essence, entitled to discriminate—a right arguably embodied by the First Amendment freedom of expressive association. When campus groups actually exercise this right, however, they run into university antidiscrimination policies, which can cost them official campus recognition. …


Here Comes The Sun: Solar Power Parity With Fossil Fuels, Nathan Mee, Marc Miller Dec 2011

Here Comes The Sun: Solar Power Parity With Fossil Fuels, Nathan Mee, Marc Miller

William & Mary Environmental Law and Policy Review

There is wide agreement across the political spectrum that the United States should develop domestic, renewable sources of energy. There are many ways to describe the challenges of a transition from a fossil fuel economy to one fueled by atoms, the sun, or the wind, but in a nutshell, the problem is said to be cost: the basic reason the United States continues overwhelmingly to rely on fossil fuels is that they are comparatively cheap, and alternative energy is relatively expensive.

Or so it seems. This Article is intended to encourage more open discussion about real energy costs. To keep …

The State And Future Of Genocide Studies And Prevention: An Overview And Analysis Of Some Key Issues, Samuel Totten Dec 2011

The State And Future Of Genocide Studies And Prevention: An Overview And Analysis Of Some Key Issues, Samuel Totten

Genocide Studies and Prevention: An International Journal

In addition to providing a succinct history of the field of genocide studies, this article examines such issues as the critical need to address the toughest barriers to the prevention of and intervention against genocide (e.g., realpolitik, the lack of political will, and the reform of the UN Security Council, including the make-up and operation of the Permanent Five members [Great Britain, US, France, Russia, and China]); whether the Crimes Against Humanity Initiative will make a real difference vis-a`-vis the prevention of and intervention against genocide; the critical need for the field to be more inclusive by welcoming and nurturing …


Hydrologic Evaluation Of Established Rain Gardens In Lincoln, Nebraska Using A Storm Runoff Simulator, Andrew R. Anderson Dec 2011

Hydrologic Evaluation Of Established Rain Gardens In Lincoln, Nebraska Using A Storm Runoff Simulator, Andrew R. Anderson

Department of Environmental Engineering: Theses and Other Student Research

Increased urbanization has resulted in water quality and flooding problems for many receiving waters in the United States. Bioretention, or rain gardens, is one of the most widely popular and effective best management practices in low impact development (LID), which strives to return a watershed to a predevelopment hydrologic regime. Many studies have evaluated large bioretention cells in research settings. There is little information on the effectiveness of homeowner-maintained rain gardens that rely on deep percolation as the method for water exfiltration. Additionally, few studies address rain garden performance in cold, arid, or semi-arid climates found in the Midwest U.S. …

Tracking Web Video Topics: Discovery, Visualization, And Monitoring, Juan Cao, Chong-Wah Ngo, Yong-Dong Zhang, Jin-Tao Li

Research Collection School Of Computing and Information Systems

Despite the massive growth of web-shared videos in Internet, efficient organization and monitoring of videos remains a practical challenge. While nowadays broadcasting channels are keen to monitor online events, identifying topics of interest from huge volume of user uploaded videos and giving recommendation to emerging topics are by no means easy. Specifically, such process involves discovering of new topic, visualization of the topic content, and incremental monitoring of topic evolution. This paper studies the problem from three aspects. First, given a large set of videos collected over months, an efficient algorithm based on salient trajectory extraction on a topic evolution …


Towards Textually Describing Complex Video Contents With Audio-Visual Concept Classifiers, Chun Chet Tan, Yu-Gang Jiang, Chong-Wah Ngo Dec 2011

Towards Textually Describing Complex Video Contents With Audio-Visual Concept Classifiers, Chun Chet Tan, Yu-Gang Jiang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Automatically generating compact textual descriptions of complex video contents has wide applications. With the recent advancements in automatic audio-visual content recognition, in this paper we explore the technical feasibility of the challenging issue of precisely recounting video contents. Based on cutting-edge automatic recognition techniques, we start from classifying a variety of visual and audio concepts in video contents. According to the classification results, we apply simple rule-based methods to generate textual descriptions of video contents. Results are evaluated by conducting carefully designed user studies. We find that the state-of-the-art visual and audio concept classification, although far from perfect, is able …


Four-Jet Final State Production In E+E- Collisions At Centre-Of-Mass Energies Of 130 And 136 Gev, D. Buskulic, M. Thulasidas Dec 2011

Four-Jet Final State Production In E+E- Collisions At Centre-Of-Mass Energies Of 130 And 136 Gev, D. Buskulic, M. Thulasidas

Research Collection School Of Computing and Information Systems

The four-jet final state is analyzed to search for hadronic decays of pair-produced heavy particles. The analysis uses the ALEPH data collected at LEP in November 1995 at centre-of-mass energies of 130 and 136 GeV, corresponding to a total integrated luminosity of 5.7 pb1 . An excess of four-jet events is observed with respect to the standard model predictions. In addition, these events exhibit an enhancement in the sum of the two di-jet masses around 105 GeV/c 2 . The properties of these events are studied and compared to the expectations from standard processes and to pair production hypotheses


From Primordial Soup To Platform-Based Competition: Exploring The Emergence Of Products, Systems, And Platforms, C. Jason Woodard, Eric K. Clemons Dec 2011

From Primordial Soup To Platform-Based Competition: Exploring The Emergence Of Products, Systems, And Platforms, C. Jason Woodard, Eric K. Clemons

Research Collection School Of Computing and Information Systems

We use an agent-based NK model to explore the conditions under which standard platforms emerge among competing products. Our findings were inconclusive. We find that the usual Darwinian conditions needed for the emergence of complexity are sufficient to yield a limited reliance upon platforms with a core of common components, simply because evolution causes the population to converge on a set of products that contain combinations that "work well," yielding what we call "coincidental platform emergence." Economies of scale yield more use of common components, or "production platform emergence." Positive participation externalities initially induce the highest degree of platform emergence …


Nanoparticle Necklace Network Arrays Exhibiting Room Temperature Single-Electron Switching, Jennifer L. Kane Dec 2011

Nanoparticle Necklace Network Arrays Exhibiting Room Temperature Single-Electron Switching, Jennifer L. Kane

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

A single nanoparticle is one of the most sensitive electronic devices for sensing chemicals in a gas or liquid. The conductivity of a single Au nanoparticle is significantly modulated by the binding of a molecule that alters charge by just one electron. However, the single-electron sensitivity requires cryogenic temperatures and interconnection is not easy. A patterned two-dimensional network of one-dimensional nanoparticle necklaces made up of 10 nm Au particles are fabricated and shown to exhibit similar single-electron effect at room temperature. Furthermore, the long range conductivity of over 10’s of microns makes the structure easy to self-assemble onto conventional microelectronics …


Strength Of Polycrystalline Ceramics Under Shock Compression, Jianbin Zhu Dec 2011

Strength Of Polycrystalline Ceramics Under Shock Compression, Jianbin Zhu

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

Determinations of Some polycrystalline ceramics’ strength properties and inelastic deformation mechanisms in the shocked state are critically important to the design and optimization of armor structures involving these materials. In this work, multiscale modeling and simulations have been carried out to study strength of the effects of polycrystalline microstructure, crystal anisotropy, porosity, and their interactions with microscopic deformation/damage mechanisms on the responses of several polycrystalline ceramics under shock compression and to extract their shock strengths from the wave profiles measured in the related plate impact shock wave experiments.

With a mesoscopic computational model, the roles of intragranular microplasticity and deformation …

Expanding The Length Of Jointless Bridges By Providing Rotational Capacity Over The Pile Head, Ardalan Sherafati Dec 2011

Expanding The Length Of Jointless Bridges By Providing Rotational Capacity Over The Pile Head, Ardalan Sherafati

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Jointless bridges have been in service for more than 50 years. Since no expansion joint is utilized in these structures, they have longer service life, reduced maintenance and construction costs, improved riding quality, and added redundancy. Because of integrity of the superstructure with the substructure, the thermal movements as well as other longitudinal movements are transferred to substructure. These lateral movements can induce relatively large forces and moments in the substructure elements including the abutment and the piles. Typically, flexible foundations which include single row of piles are preferred in jointless bridges to reduce the stiffness of the system against …

A Quantitative Performance Analysis Of 2.5 Ghz And 3.65 Ghz Mobile Wimax, Pradhumna L. Shrestha

Department of Computer Electronics and Engineering: Dissertations, Theses, and Student Research

Mobile WiMAX has emerged as a prime contender for the de-facto ITU’s 4G standard. It provides high data rate with large coverage and vehicular mobility support. It has been, and is being, widely deployed in diverse applications like video streaming, broadcasting and data service. The FCC (Federal Communications Commission) issues licenses to operate Mobile WiMAX services in several spectrums, among which 2.5 GHz and 3.65 GHz are the most common. Because the 2.5 GHz spectrum suffers the least propagation losses, it has been widely applied commercially. For this reason, academic and industrial researchers have given it particular attention. However, in …


A Novel Telecommunications-Based Approach To Mathematical Modeling Of Hiv Infection, Aaron T. Sharp Dec 2011

A Novel Telecommunications-Based Approach To Mathematical Modeling Of Hiv Infection, Aaron T. Sharp

Department of Computer Electronics and Engineering: Dissertations, Theses, and Student Research

It is well known that biological systems utilize communication in some form, one prolific example of this is the propagation of HIV (Human Immunodeficiency Virus) in the human body. By modeling HIV infection as a communication system, we hope to gain a unique insight into HIV and biological communication systems in general. Such a model would provide researchers a platform for experimenting and simulating various biological communication systems. We have previously developed a layered communication protocol for interpreting biological communication systems using telecommunications paradigms and will apply said model to HIV proliferation. We will also demonstrate the effectiveness of the …


Corporate Office Employee Analysis: Transformation From Closed Office Layout To Open Floor Plan Environment, Stephanie J. Fanger Dec 2011

Corporate Office Employee Analysis: Transformation From Closed Office Layout To Open Floor Plan Environment, Stephanie J. Fanger

Architecture Masters of Science Program: Theses

The office workplace within the United States has undergone monumental changes in the past century. The Environmental Protection Agency (EPA) has cited that Americans spend an average of 90 percent of their time indoors. As human beings can often spend a majority of the hours in the day at their workplace, more so than their home, it is important to understand the effects of the built environment on the American office employee. In order to stay current with modern times, General Dynamics, a corporation located in Scottsdale, Arizona implemented a renovation of interior space. This thesis examines the transformation from …
