Party As A "Political Safeguard Of Federalism": Martin Van Buren And The Constitutional Theory Of Party Politics, Gerald F. Leonard

Faculty Scholarship

In the last decade or so, the Supreme Court has revitalized judicial enforcement of federalism. This development has spurred the partisans of Herbert Wechsler's "political safeguards of federalism" to begin a serious investigation of the ways in which extra-judicial politics can and does substitute for and complement the judicial role in enforcing federalism and the Constitution. Similarly, constitutional scholars have turned in increasing numbers to the question of how even judicially promulgated doctrines of constitutional law turn out to be more derivative of popular politics than vice versa. Necessarily, much of the investigation on both fronts has turned historical and …

Tying Law And Policy: A Decision-Theoretic Approach, Keith N. Hylton, Michael Salinger

Faculty Scholarship

This paper offers a decision theoretic framework for analyzing tying law, and presents a critical assessment of post-Chicago tying theory. The decision theoretic framework takes into account the likelihood of judicial error in the application of rules and the costs of such error. We use the decision theoretic framework to assess the proper legal rules regarding tying and technological integration. Three general themes run throughout much of our analysis. First, the per se rule against tying simply has no economic foundation. Second, while the post-Chicago literature established the theoretical possibility of anticompetitive tying, one must know the frequency of anticompetitive …

Bankruptcy Law V. Privacy Rights: Which Holds The Trump Card?, Walter W. Miller Jr., Maureen A. O'Rourke

Faculty Scholarship

The Internet's emergence as a retail marketplace has both posed new issues and cast old problems in a new light. As technology, particularly software, has advanced over time, traditional bricks and mortar firms have acquired the capability of tracking and analyzing all sorts of information about their customers, including purchasing patterns and demographic information. For years, firms have been licensing and selling such customer data both in and out of bankruptcy without much fear of legal limitations. In particular, the law has generally not adopted privacy rules that would present a barrier to commerce in personal information.

Combining Ordering Heuristics And Bundling Techniques For Solving Finite Constraint Satisfaction Problems, Amy Beckwith, Berthe Y. Choueiry

School of Computing: Technical Reports

We investigate techniques to enhance the performance of backtrack search procedure with forward-checking (FC-BT) for finding all solutions to a finite Constraint Satisfaction Problem (CSP). We consider ordering heuristics for variables and/or values and bundling techniques based on the computation of interchangeability. While the former methods allow us to traverse the search space more effectively, the latter allow us to reduce it size. We design and compare strategies that combine static and dynamic versions of these two approaches. We show empirically the utility of dynamic variable ordering combined with dynamic bundling in both random problems and puzzles.

Optimization Of Amplifier Placements In Switch-Based Optical Networks, Ling Zong, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Wavelength division multiplexing (WDM) offers a solution to the problem of exploiting the large bandwidth on optical links; it is the current favorite multiplexing technology for optical communication networks. Due to the high cost of an optical amplifier, it is desirable to strategically place the amplifiers throughout the network in a way that guarantees that all the signals are adequately amplified while minimizing the total number amplifiers being used. Previous studies all consider a star-based network. This paper demonstrates an original approach for solving the problem in switch-based WDM optical network assuming the traffic matrix is always the permutation of …

The Impact Of Software Evolution On Code Coverage Information, Sebastian Elbaum, David Gable, Gregg Rothermel

School of Computing: Conference and Workshop Papers

Many tools and techniques for addressing software maintenance problems rely on code coverage information. Often, this coverage information is gathered for a specific version of a software system, and then used to perform analyses on subsequent versions of that system without being recalculated. As a software system evolves, however, modifications to the software alter the software’s behavior on particular inputs, and code coverage information gathered on earlier versions of a program may not accurately reflect the coverage that would be obtained on later versions. This discrepancy may affect the success of analyses dependent on code coverage information. Despite the importance …

Technology As The Representative Anecdote In Popular Discourses Of Health And Medicine, Lynn M. Harter, Phyllis Japp

Department of Communication Studies: Faculty Publications

Using a Burkean framework (1969), this article approaches medical dramas as cultural texts to be read for dominant meanings of health and health care. Burke’s representative anecdote illuminates the melding of science, technology, and healing in popular discourses of health, establishing technological intervention as the norm and marginalizing nontechnological (i.e., alternative) forms of health care. Popular entertainment reinforces this anecdote in narratives of healing as technological competence triumphing over nature.

A Generator Of Random Instances Of Binary Finite Constraint Satisfaction Problems With Controllable Levels Of Interchangeability, Hui Zou, Amy Beckwith, Berthe Y. Choueiry

School of Computing: Technical Reports

In order to test the performance of algorithms for solving Constraint Satisfaction Problems (CSPs), we must establish a large collection of CSP instances that meet a given set of specifications, such as the number of variables, domain size, constraint density, tightness, etc. The goal of this report is to describe a generator of instances that have a specified degree of interchangeability. An example of such a generator is described in (Freuder and Sabin 1997), which generates non-reflexive constraints and does not allow us to control concurrently the degree of interchangeability and tightness. We have developed a technique and written a …

Optimization Of Orthogonal Polyphase Spreading Sequences For Wireless Data Applications, B. J. Wysocki, Tadeusz Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

In this paper, we propose a simple but efficient method for optimizing correlation properties of polyphase spreading sequences for asynchronous DS CDMA applications. The proposed method can be used to minimize the mean square value of aperiodic crosscorrelation or the mean square value of aperiodic autocorrelation, the maximum value of aperiodic crosscorrelation functions, merit factor or other properties of the sequence set. The important feature of the method is that when applied to orthogonal sequences, it modifies correlation properties of the sequence set, while preserves their orthogonality for perfect synchronization.

Infrastructure Support For Controlled Experimentation With Software Testing And Regression Testing Techniques, Hyunsook Do, Sebastian Elbaum, Gregg Rothermel

School of Computing: Technical Reports

Where the creation, understanding, and assessment of software testing and regression testing techniques are concerned, controlled experimentation is an indispensable research methodology. Obtaining the infrastructure necessary to support such experimentation, however, is difficult and expensive. As a result, progress in experimentation with testing techniques has been slow, and empirical data on the costs and effectiveness of techniques remains relatively scarce. To help address this problem, we have been designing and constructing infrastructure to support controlled experimentation with testing and regression testing techniques. This paper reports on the challenges faced by researchers experimenting with testing techniques, including those that inform the …

Hierarchical Ring Network Configuration And Performance Modeling, V. Carl Hamacher, Hong Jiang

School of Computing: Faculty Publications

Approximate analytical queuing network models for expected message packet delay in 2-level and 3-level hierarchical ring interconnection networks (INs) are developed. A major class of traffic carried by these INs consists of cache line transfers between processor caches and remote memory modules in shared-memory multiprocessors. Such traffic consists of short, fixed-length messages; they can be conveniently transported by the slotted-ring transmission technique which is studied here. The packet delay results derived from the models are shown to be quite accurate when checked against a simulation study. As well as facilitating analysis, the analytical models can be used to determine optimal …

Hierarchy-Based Access Control In Distributed Environments, Jean-Camille Birget, Xukai Zou, Guevara Noubir, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Access control is a fundamental concern in any system that manages resources, e.g., operating systems, file systems, databases and communications systems. The problem we address is how to specify, enforce, and implement access control in distributed environments. This problem occurs in many applications such as management of distributed project resources, e-newspaper and payTV subscription services.

Starting from an access relation between users and resources, we derive a user hierarchy, a resource hierarchy, and a unified hierarchy. The unified hierarchy is then used to specify the access relation in a way that is compact and that allows efficient queries. It is …

The Effects Of Multitasking On Quality Inspection In Advanced Manufacturing Systems, Jose A. Pesante, Robert C. Williges, Jeffrey C. Woldstad

Department of Industrial and Management Systems Engineering: Faculty Publications

Although the industrial quality inspection task has been extensively studied, the effect of multitasking on the performance of the operator in a hybrid inspection system is still unknown. The experiment described in this article compared the quality inspection performance for participants performing a single task, 3 multiple tasks, and 5 multiple tasks. The results of this research indicate that the performance of the operator in the quality inspection task while multitasking in an advanced manufacturing system will be determined by the interaction between the number of different types of defects that can be presented at the same time in the …

Tracking Of Moving Objects In Scenery Using Subspace Projection Using Independent Component Analysis, Brian J. Noe, Fredric M. Ham

Aerospace, Physics, and Space Science Faculty Publications

A system is developed for tracking moving objects though natural scenery. A technique is presented for performing change detection on imagery to determine the difference between two images or a sequence of images. Form there an algorithm is presented to detect the presence of a new object and/or the deletion of objects. Then the application of a Variable Structure Interacting Multiple Model tracking filter is presented. The method of performing change detection is based upon the concept of image subspace projection. A set of basis image maps are formed when combined with a mixing matrix can recreate the original image. …

A Direct Correlation Function For Mesomorphic Polymers And Its Application To The ‘Smectic’ Phase Of Isotactic Polypropylene, Y Cohen, Ravi F. Saraf

Papers in Materials Science

A general model to calculate the structure of a smectic to nematic-like order in polymer systems is proposed. The model is limited to well-aligned molecules with respect to each other. It is especially suited for systems where the packing between neighboring chains is described by liquid-like disorder with axial registration in the chain-axis direction. In such a case the diffraction pattern from the oriented structure exhibits broad liquid-like reflections on the equatorial but sharper reflections on the layer lines. An Ornstein-Zernike approach is adopted to calculate the inter-chain packing and inter-chain registration, where the direct correlation function of packing and …

Relationship Between Durophagy And Feeding Biomechanics In Gray Triggerfish, Balistes Capriscus: Intraspecific Variation In Ecological Morphology, Christopher J. Durie, Ralph G. Turingan

Ocean Engineering and Marine Sciences Faculty Publications

The relationship between oral jaw biomechanics and consumption of hard prey was compared between Gulf of Mexico (Gulf) and Atlantic Ocean (Atlantic) populations of gray triggerfish (Balistes capriscus) to examine intraspecific ecomorphological variation between these fish. Gut content analysis revealed that Atlantic fish fed more on hard-shelled invertebrates, such as crabs and sea urchins, than Gulf conspecifics. Difference in the relative magnitude of durophagy between Gulf and Atlantic triggerfish was associated with intraspecific differences in key biomechanical properties of the prey-capture and processing mechanism. The more durophagous Atlantic B. capriscus had more massive jaw bones and muscles than Gulf fish. …

The Economic Case For Labor Standards: A Layman’S Guide, Thomas I. Palley

Richmond Journal of Global Law & Business

The place of labor standards in the global economy has figured prominently in recent discussions of trade and globalization. Labor standards figured prominently in the Seattle meeting of the World Trade Organization (WTO) in 1999, and they promise to figure prominently in discussions about a proposed Free Trade Area of Americas (FTAA). Labor standards represent a critical issue for both the American labor movement and the international trade union movement as they are central to making globalization work for working people.

Mathematization And Modern Science, Calvin Jongsma

Faculty Work Comprehensive List

The discipline of mathematics has not been spared the sweeping critique of postmodernism. Is mathematical theory true for all time, or are mathematical constructs in fact fallible? This fascinating book examines the tensions that have arisen between modern and postmodern views of mathematics, explores alternative theories of mathematical truth, explains why the issues are important, and shows how a Christian perspective makes a difference.

This chapter continues the process of tracing Western mathematization.

Campaign Of Sabotage: Big Government's War Against Public Transportation, Michael Lewyn

Scholarly Works

Historically, American politicians have been far more generous to highways than to public transit. The political elite's failure to support public transit is based on the view that despite decades of state and federal support, transit ridership has dwindled. This article criticizes that theory, by explaining that far from promoting public transit, government at all levels has sabotaged transit in a variety of ways: by building highways to suburbs unserved by public transit, by loading down transit systems with unfunded mandates, by using housing, education and tax policy to encourage migration to those suburbs, and by using zoning policy to …

Modeling And Fabrication Of Lightweight, Deformable Mirrors Subjected To Discrete Loading, Michael E. Roche

University of Kentucky Master's Theses

The push towards larger diameter space telescope mirrors has caused the space industry to look at lightweight, deformable alternatives to the traditional monolithic mirror. One possible solution to the dilemma is to use the piezoelectric properties of certain materials to create a lightweight, deformable mirror. Current piezoelectric deformable mirror designs use individual actuators, creating an immensely complex system as the mirrors increase in size. The objective of this thesis is to aid in the design and development of lightweight, deformable mirrors for use in space based telescopes. Two topics are considered to aid this development. A doubly curved, lightweight, bimorph …

Risk Based Urban Watershed Management Under Conflicting Objectives, Vladimir Novotny, David E. Clark, Robert J. Griffin, Douglas Booth

Economics Faculty Research and Publications

Ecological impairment and flooding caused by urbanization can be expressed numerically by calculating the risks throughout the watershed (floodplain) and along the main stems of the streams. The risks can be evaluated in terms of the present and/or future. This article describes the methodologies for ascertaining the risks in the Geographical Information Systems (GIS) environment. The objectives of urban flood controls and ecological preservation/restoration of urban waters are often conflicting and, in the past, the sole emphasis on flood control led to destruction of habitat and deterioration of water quality. An optimal solution to these two problems may be achieved …
