The spin structure functions g1 for the proton and the deuteron have been measured over a wide kinematic range in x and Q² using 1.6 and 5.7 GeV longitudinally polarized electrons incident upon polarized NH3 and ND3 targets at Jefferson Lab. Scattered electrons were detected in the CEBAF Large Acceptance Spectrometer, for 0.05 < Q² < 5GeV² and W < 3 GeV. The first moments of g1 for the proton and deuteron are presented – both have a negative slope at low Q², as predicted by the extended Gerasimov–Drell–Hearn sum rule. The first extraction of the generalized forward spin polarizability of the proton γ p 0 the Q² evolution of the first moment of g1 shows agreement in leading order with Heavy …

Photodisintegration Of 4He Into P+T, Clas Collaboration, M. J. Amaryan, S. L. Careccia, G. E. Dodge, C. E. Hyde, S. E. Kuhn, M. Mayer, C. S. Nepali, M. R. Niroula, H. Seraydaryan, S. Tkachenko, L.B. Weinstein, J. Zhang

Physics Faculty Publications

The two-body photodisintegration of 4He into a proton and a triton has been studied using the CEBAF Large-Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility. Real photons produced with the Hall-B bremsstrahlung-tagging system in the energy range from 0.35 to 1.55 GeV were incident on a liquid ⁴He target. This is the first measurement of the photodisintegration of ⁴He above 0.4 GeV. The differential cross sections for the γ ⁴He →pt reaction were measured as a function of photon-beam energy and proton-scattering angle and are compared with the latest model calculations by J.-M. Laget. At …

Octamethoxydibenzochrysene: Isolation And X-Ray Crystallographic Characterization Of A Twisted Polyaromatic Cation Radical, Tushar Navale, Linyi Zhai, Sergey V. Lindeman, Rajendra Rathore

Chemistry Faculty Research and Publications

The isolation and X-ray crystal structure determination of octamethoxydibenzochrysene (3) cation radical together with DFT calculations allow us to delineate evidence that the complex structural changes (i.e. elongation and shortening of various bonds) in a polyaromatic hydrocarbon can be predicted based on the positioning of the largest bonding and antibonding character of the HOMO.

Revisiting Hateful Science: The Nazi “Contribution” To The Journey Of Antisemitism, Steven Leonard Jacobs

Journal of Hate Studies

While this volume of the Journal of Hate Studies is devoted to “The Science of Hate”—research and knowledge about hate’s origins and manifestations seen through the lens of the empirical sciences—this contribution is a cautionary reminder that, like all human projects, intellectual and other, the sciences, too, can be perverted by its practitioners in the service of hate itself.1 The case study is that of the Nazi Otmar Freiherr von Verschuer, MD, (1896-1969), eugenicist and geneticist, and, specifically, his (1938) text “Racial Biology of the Jews.” Of particular note is the American “connection,” in supplying both supporting legitimation for the …

Ulf Schmidt’S Karl Brandt – The Nazi Doctor: Medicine And Power In The Third Reich And Justice At Nuremberg: Alexander And The Nazi Doctors’ Trial, Edmund Glaser

Journal of Hate Studies

My initial thought on encountering Justice at Nuremberg was that finally I would have the chance to get to know the defendants, whom at age 19 I personally encountered and photographed as a member of the U.S. Army’s photo detachment assigned to officially document the Trial with sound movies. (The movies are now in the U.S. National Archives.) For several months I observed the sullen and glum defendants, trying to penetrate what turned out to be their impenetrable visages. In the subsequent years of my continued interest and intermittent searching, I turned up nothing more than bits and pieces of …

Reputation, Information And The Organization Of The Judiciary, Nuno Garoupa, Tom Ginsburg

Faculty Scholarship

The reputation of the judiciary, individually or as a whole, determines its status in any given society and its ability to compete effectively for resources. We analyze reputation and make three claims. First, reputation matters. Virtually every theory of judicial power is dependent, ultimately, on perceptions of judges, who famously lack the purse or the sword. Our second claim is that reputation can be divided into individual and collective components. Individual reputation provides information about individual performance whereas collective reputation provides information about the quality of the judiciary in general. We use the economics of team production to analyze the …

Judicial Audiences And Reputation: Perspectives From Comparative Law, Nuno Garoupa, Tom Ginsburg

Faculty Scholarship

Whether judges are motivated to make good law or maximize policy goals, they need to develop and maintain a good reputation with some audience. We distinguish internal and external audiences for individual judicial decision-making: internal audiences are those within the judiciary itself, while external audiences include lawyers, the media or the general public. Different legal systems emphasize different audiences: some rely on external audiences that encourage judges to invest in their individual reputations, while others emphasize internal audiences that facilitate the collective reputation of the judiciary as a whole. The article analyzes the interaction between internal and external audiences over …

A 'Ho New World: Raced And Gendered Insult As Ersatz Carnival And The Corruption Of Freedom Of Expression Norms, Lolita Buckner Inniss

Faculty Journal Articles and Book Chapters

Carnivalization, a concept developed by literary theorist Mikhail Bakhtin and later employed in broad social and cultural contexts, is the tearing down of social norms, the elimination of boundaries and the inversion of established hierarchies. It is the world turned upside down. Ersatz carnival is a pernicious, inverted form of carnival, one wherein counter discourses propounded by outsiders are appropriated by elites and frequently redeployed to silence and exclude those same outsiders. The use of the slur 'ho by gangsta' rappers in the performance of songs that articulate a vision of urban culture is an example of carnivalization. However, when …

Notice Otherwise Given: Will In Absentia Trials At The Special Tribunal For Lebanon Violate Human Rights?, Chris Jenks

Faculty Journal Articles and Book Chapters

On March 1, 2009, the Special Tribunal for Lebanon (STL) commenced operations in the Netherlands. The mandate of the STL is to try those allegedly responsible for the 2005 bombing in Beirut which killed former Lebanese Prime Minister Rafiq Hariri. A collaborative effort between Lebanon and the United Nations, the STL is to be of “international character based on the highest standards of justice.” However, the STL’s in absentia trial provisions are based on a far different, and lower, standard. This article posits that the STL’s in absentia trial provisions violate human rights norms, indeed the U.N. expressly rejected such …

Making Pregnancy Work: Overcoming The Pregnancy Discrimination Act's Capacity-Based Model, Joanna L. Grossman, Gillian Thomas

Faculty Journal Articles and Book Chapters

This article considers the gaps and obstacles in current law faced by the pregnant woman whose job duties may conflict with pregnancy's physical effects. While there is no inherent conflict between pregnancy and work, women in physically strenuous or hazardous occupations, from nursing to law enforcement, routinely confront situations in which they are physically unable to perform aspects of their job or, though physically able, they seek to avoid certain tasks or situations because of the potential risks to maternal or fetal health. The Pregnancy Discrimination Act of 1978 (PDA) broadly protects against "pregnancy discrimination," but it provides absolute rights …

International Health Care Convergence: The Benefits And Burdens Of Market-Driven Standardization, Nathan Cortez

Faculty Journal Articles and Book Chapters

For over thirty years, health scholars have debated whether health care policies are converging, or becoming more alike, internationally. Convergence theories have always been particularly appealing in health care. Most countries generally struggle with the same challenges: how to provide quality care, to as many people as possible, for a reasonable price. Moreover, modern scientific medicine has not only influenced how countries around the world provide and regulate health care, but has also driven rising patient expectations. These commonalities invite theories of convergence: If policymakers in different jurisdictions face similar challenges, why wouldn't they adopt roughly similar solutions?

In this …

Double Jeopardy And Multiple Sovereigns: A Jurisdictional Theory, Anthony J. Colangelo

Faculty Journal Articles and Book Chapters

This Article offers a coherent way of thinking about double jeopardy rules among sovereigns. Its theory has strong explanatory power for current double jeopardy law and practice in both U.S. federal and international legal systems, recommends adjustments to double jeopardy doctrine in both systems, and sharpens normative assessment of that doctrine.

The Article develops a jurisdictional theory of double jeopardy under which sovereignty signifies independent jurisdiction to make and apply law. Using this theory, the Article recasts the history of the U.S. Supreme Court's dual sovereignty doctrine entirely in terms of jurisdiction, penetrating the opacity of the term sovereign as …

Three Ways Of Looking At A Health Law And Literature Class, Jennifer S. Bard, Thomas Wm. Mayo, Stacey A. Tovino

Faculty Journal Articles and Book Chapters

The authors of this Article participated in a panel at the American Society of Law, Ethics & Medicine Conference in 2008 that discussed the use of literary materials in law school to teach medical ethics (and related matters) in a law school setting. Each author comes at the topic from a different perspective based on his or her own experience and background. This Article and the panel on which it was based reflect views on how literature can play a valuable role in helping law students, as well as medical students, understand important legal and ethical issues and concepts in …

Rethinking Consideration In The Electronic Age, Robert A. Hillman, Maureen A. O'Rourke

Faculty Scholarship

Our fast-paced age of electronic agreements that ostensibly govern transactions as diverse as downloading software, ordering goods, and engaging in collaborative development projects raises questions regarding thesuitability of contract law as the appropriate legal framework. While this question arises in many settings, we focus here on the free and open source software (FOSS) movement because of the maturity and success of its model and the ubiquity of its software. We explore in particular whether open source licenses are supported by consideration, and argue that they are, and that open source licenses are contracts. We further argue that a contractual framework …

Zigbee-Enabled Structural Health Monitoring Using The Smartbrick System, Tyler Harms

Masters Theses

"This thesis describes the design, testing, and proposed extended field test of a wireless sensor network based on the SmartBrick, a structural health monitoring (SHM) device developed at Missouri S&T. The SmartBrick serves as the base station for the network, which utilizes additional sensor nodes to monitor the structure. Each node measures a range of environmental and structural phenomena, including vibration, tilt, humidity, and strain. The nodes use Zigbee short-range communication to transmit their data to the base station, which in turn uses the GSM cellular network to provide long-range communication capability and support for remote control.

Unlike many SHM …

Vehicle Positioning Using Image Processing, Armadeep Kaur

Masters Theses

"An imaging-processing approach is described that detects the position of a vehicle on a bridge or similar environment. A load-bearing vehicle must be carefully positioned on a bridge for quantitative bridge monitoring. The personnel required for setup and testing and the time required for bridge closure or traffic control are important management and cost considerations. Consequently, bridge monitoring and inspections are good candidates for smart embedded systems. The objectives of this work are to reduce the need for personnel time and to minimize the time for bridge closure. An approach is proposed that uses a passive target on the bridge …

Development And Use Of Computer Aided Tools To Enhance Team Dynamics With Role Play Simulations, Vachaspathy Kuntamukkala

Masters Theses

"This thesis proposes a methodology for the development and use of computer based tools to enhance student team dynamics. Working effectively in groups cannot be taught in class room environment. Students often encounter conflicts during team meetings. Although some conflicts are resolved by the efforts of team members, an unbiased facilitator who is not a member of the team is often needed to help. This work proposes a tool that uses role play simulations to engage students in real-life scenarios so that they gain a practical, as well as a theoretical, understanding of how to work effectively as a team. …

An Evolutionary Algorithm Approach To Actuated Signal Timing Optimization Under Lane-By-Lane Detection Condition, Eric G. Strack

Masters Theses

"Motivated by the need to reduce congestion on the nation's roadway network, this research seeks to determine when a new detection scheme at actuated signalized intersections may help. This new detection scheme is called lane-by-lane detection. It "looks" at traffic in all lanes individually to determine the traffic volume on the roadway. Specifically, the problems addressed are investigating alternate signal timings and investigating the traffic volume's effect on performance of the detection scheme. For the alternate signal timings, an Evolutionary Algorithm (EA) was employed to identify the optimal signal timing. This algorithm creates signal timings and tests them in the …

Satellite Photography: Instrumental, Rhetorical, Affective?, Irangi Kaushalya Egodapitiya

Masters Theses

"This study examines how tsunami satellite images operate and could provoke various interpretations. The goal of this research project is to study whether the interpretation of tsunami satellite images could extend beyond scientific features to affective messages. Primarily based on the satellite images of Sri Lanka taken before and during the 2004 tsunami, this study analyses: How could mechanical satellite images, taken automatically by a machine in orbit, become an object of profound emotional meaning?; How do viewer's experiences, knowledge, and discourse affect their interpretations of mechanical artifacts?; How are tsunami satellite images connected to affective responses by viewers?; How …

Information Flow Properties For Cyber-Physical Systems, Rav Akella

Masters Theses

"In cyber-physical systems, which are the integrations of computational and physical processes, security properties are difficult to enforce. Fundamentally, physically observable behavior leads to violations of confidentiality. This work analyzes certain noninterference based security properties to ensure that interactions between the cyber and physical processes preserve confidentiality. A considerable barrier to this analysis is the representation of physical system interactions at the cyber-level. This thesis presents encoding of these physical system properties into a discrete event system and represents the cyber-physical system using Security Process Algebra (SPA). The model checker, Checker of Persistent Security (CoPS) shows Bisimulation based NonDeducibility on …

Communication Models For Monitoring And Mobility Verification In Mission Critical Wireless Networks, Maheswaran Thiagarajan

The Componentization Of Information, Kristen Jakobsen Osenga

Law Faculty Publications

Information is ‘the oxygen of the modern age’. Despite its importance, or perhaps because of it, conventional wisdom has long been of the view that information wants to, or even needs to, be free. This idea has been extended to encompass not just raw data, but also information products such as databases and software. These products – products whose primary value lies in organizing, providing context, and distributing information content – have often been the subject of debate over whether and to what extent these works should be protected. The tension between information being free and information products being protected …

Popular Constitutionalism, Civic Education, And The Stories We Tell Our Children, Thomas G. Donnelly

Law Faculty Publications

This Note analyzes a set of constitutional stories that has not been the subject of focused study—the constitutional stories we tell our schoolchildren in our most widely used high school textbooks. These stories help reinforce a constitutional culture that is largely deferential to the Supreme Court, limiting references to popular resistance to the Court and often linking such popular resistance to the actions of self-interested politicians, at best, and historical villains, at worst. Our textbooks are especially critical of blunt institutional checks on the Court (like judicial impeachment and “court-packing”), but are sometimes receptive to subtler, longer-term checks (like social …

Exploring The Use Of A Commercial Game Engine For The Development Of Educational Software, Hussain Alafaireet

Masters Theses

"Three-dimensional visualization and simulation environments are becoming increasingly important in both industrial and educational environments. However, developing these simulations can be a difficult and expensive task. Herein we explore the use of a commercial game engine to develop a 3-D, interactive computer game designed to teach players about the anatomy of a frog. The goal of this project is threefold: 1) to develop high-fidelity virtual reality educational software with a limited budget and limited personnel, 2) to define a software development process by which similar simulations can be developed, and 3) to explore the benefits that these simulations provide to …

On The Effects Of Small-Scale Fading And Mobility In Mobile Wireless Communication Network, Bandana Paudel

Masters Theses

"In this study, a comprehensive analysis of the impact of mobility on end-to-end performance measures of Mobile Ad Hoc Network is performed by using small-scale fading models. Network simulation is performed in order to study a wide range of phenomena occurring during MANET communication. The effectiveness of three reactive routing protocols against different level of mobility is observed under varying network parameter like the network size, number of nodes and network connectivity. The study reveals that the network sparseness or density favors one or the other routing mechanism under varying mobility. Outcome of the simulation also provides a great deal …
