Ideology, Racism And Morality: Investigating The Structural Origins Of Drug Prohibition, John P. Hoffmann

Faculty Publications

This paper explores the origins of drug prohibition in the United States from a structural perspective. The primary locus ,son how certain economic conditions in U.S. history influenced attitudes toward racial and ethnic minorities during the 1800s and early 1900s. and indirectly affected the passage or prohibitory drug laws. The economic structure continues to Influence the current illegal drug market. Moreover, some consequences of legal and illegal drug use identify the impact of the economic structure on drug prohibition.

Design Of High Performance Soft X-Ray Windows, Raymond T. Perkins, David D. Allred, Larry V. Knight, James M. Thorne

Faculty Publications

X-ray windows are used in sources and detectors to separate the neighborhood of the x-ray generation or detection from the use environment. While each use has its own requirements, there are some principles that should be used in designing an optimal x-ray window. Because x-rays are absorbed to some extent by all materials, minimizing absorption is one criterion in preparing windows. Also, for most uses there is a pressure difference across the window so that ensuring pinhole-free structure and sufficient mechanical strength to support the differential is another criterion for window design. Traditionally, absorption is minimized by fabricating the window …

Primo Levi: The Drowned, The Saved, And The "Grey Zone", Ilona Klein

Faculty Publications

Primo Levi has been well known in Italy for many years. Even though his first book Se questo è un uomo–published in English as Survival in Auschwitz–did not sell well when first published by De Silva in 1947 (2,500 copies published, of which 600 remained unsold and were eventually destroyed by the 1966 flood in Florence), it was accepted unanimously in Italy as a literary masterpiece and a great witness to history when Einaudi republished the volume in 1956. From that moment on, Italian readers and critics have acknowledged the literary beauty and importance of Levi's writings. He …

Advanced Infrared Optically Black Baffle Materials, David D. Allred, Ronald D. Seals, C. M. Egert

Faculty Publications

Infrared optically black baffle surfaces are an essential component of many advanced optical systems. All internal surfaces in advanced infrared optical sensors that require stray light management to achieve resolution are of primary concern in baffle design. Current industrial materials need improvements to meet advanced optical sensor systems requirements for optical, survivability, and endurability. Baffles are required to survive and operate in potentially severe environments. Robust diffuse-absorptive black surfaces, which are (1) thermally and mechanically stable to threats of x-ray, launch, and in-flight maneuver conditions, with specific densities to allow an acceptable weight load, (2) handleable during assembly, (3) cleanable, …

Resort Motivations For Different Family Life Cycle Stages, Brian J. Hill, Cary Mcdonald, Muzaffer Uysal

Faculty Publications

Motivational differences for resort vacation travel among family life cycle stages have not been addressed in travel research. However, from a marketing standpoint, segmenting the resort market into family life cycle groups can be reasonably important. Linking an identified group of motivat􀁄ons with these stages is the purpose of this article. Descriptive analysis, factor analysis, and analysis of variance are used to evaluate the data. Twenty motivations are . reduced into five motivation factors that coincide with established travel motivations or needs. The importance of family relationship, health and social, and fun and entertainment motivations does differ among respondents single …

Canonical Commutator And Mass Renormalization, G. W. Ford, R. F. O'Connell

Faculty Publications

The question considered is the effect on the canonical commutation rules of mass renormalization in quantum electrodynamics. This is investigated by considering the quantum Langevin equation for a charged quantum oscillator interacting with the radiation field via dipole interaction. Explicit expressions for the commutator are obtained for finite cutoff frequency as well as the large-cutoff limit. The surprising result obtained is that the exactly equal-time (canonical) commutator involves the bare mass, while the corresponding commutator for infinitesimally displaced times involves the renormalized mass. © 1989 Plenum Publishing Corporation.

Faculty Publications

Describes an advanced writing course based on a survey of historical rhetoric, from classical to twentieth-century rhetoric, linked to writing assignments using selected aspects of each period's rhetoric that reflect some current writing exigency. Originally presented to the Advanced Writing section at the South Atlantic Modern Language Association, Atlanta, GA, November 1989.

The Safety Of Maximal Exercise Testing, Larry W. Gibbons, Steven N. Blair, Harold W. Kohl Iii, Kenneth H. Cooper

Faculty Publications

Previous reports on the safety of exercise testing have been based on surveys from different testing facilities with a variety of testing protocols and patient types. From 1971 through 1987, 71,914 maximal exercise tests conducted in a population with a low prevalence of known coronary heart disease under uniform conditions at a single medical facility resulted in six major cardiac complications including one death. No complications have occurred in the past 10 years in 45,000 maximal tests. The overall cardiac complication rate in men and women is 0.8 complications per 10,000 tests with 95% confidence intervals of 0.3-1.9 complications per …

Molecular Dynamics Simulation Of Real-Fluid Mutual Diffusion Coefficients With The Lennard-Jones Potential Model, Richard L. Rowley, J. M. Stoker

Faculty Publications

Mutual diffusion coefficients for selected alkanes in carbon tetrachloride were calculated using molecular dynamics and Lennard-Jones (LJ) potentials. Use of effective spherical LJ parameters is desirable when possible for two reasons: (i) computer time is saved due to the simplicity of the model and (ii) the number of parameters in the model is kept to a minimum. Results of this study indicate that mutual diffusivity is particularly sensitive to the molecular size cross parameter, σ12, and that the commonly used Lorentz–Berthelot rules are inadequate for mixtures in which the component structures differ significantly. Good agreement between simulated and experimental mutual …

Probabilistic Segmentation Of Myocardial Tissue By Deterministic Relaxation, William A. Barrett, Shawn C. Becker, Jerome A. Broekhuijsen

Faculty Publications

A recently-developed probabilistic model for automatically segmenting regions of interest in abdominal CT scans has been adapted to the challenging task of segmenting myocardial tissue in Cine CT scans. A system has been implemented on relatively low-cost hardware which performs such segmentations. Special techniques have been developed to improve consistency and accuracy. Early results of testing this new modality are encouraging and promising. Based on observations from experimentation, new directions for future work have been identified.

A Relaxation Algorithm For Segmentation Of The Endocardial Surface From Cine Ct, William A. Barrett, Bryan S. Morse

Faculty Publications

A relaxation algorithm has been developed for automated segmentation of the endocardial surface from contrast Cine CT images. The image is contoured at an initial density threshold and a one-dimensional edge operator is applied orthogonally to each point of the contour. Output from the operator is used to generate a histogram, the mode of which identifies a new threshold. The image is contoured again at the new threshold and the process is repeated. Iteration continues with successive threshold estimates converging to a stable value in the region of the endocardial surface. Computer-determined thresholds compare favorably with manual segmentation while reducing …

Interactive Measurement Of Three-Dimensional Cardiac Morphology, William A. Barrett, Shawn C. Becker

Faculty Publications

Techniques have been developed for extracting three-dimensional (3D) measurements directly and interactively from 3D representations of Cine CT images. In order to obtain 3D measurements the anatomical surface is interrogated directly through the use of a 3D graphical "probe" (line). The probe is interactively positioned and stretched between any visible surface points to allow direct capture of 3D (linear) distance. Distance measurements are updated in real time as the probe dynamically "penetrates" any intervening anatomy while providing valuable depth cuing for visual feedback and probe placement. Curvilinear distance is obtained by stretching the probe over multiple surface points. The probe …

A Proposal For Reallocation Of Federal Grazing-Revisited, B. Delworth Gardner

Faculty Publications

Over a quarter of a century ago, I analyzed the allocation procedures utilized by the federal agencies which administer livestock grazing on the public lands (Gardner 1962). Two factors contributing to grazing misallocation and reduced range productivity were identified: (1) the "eligibility" requirements that qualify permittees for grazing privileges prevented the utilization of forage by ranchers who would value it most, and (2) use-tenure insecurity resulting from cuts in permitted grazing impeded private investment in range improvements on the public ranges. In a second paper, I proposed that the grazing privilege system be reformed such that efficient allocation of forage …

Guess Who's Coming To Worship? Worship And Evangelism, Patrick R. Keifert

Faculty Publications

Too many congregations of mainline churches profess that they welcome strangers but are inhospitable when the stranger comes to worship. They know that worship is the single most important ingredient in why people join and remain active members in a congregation. They realize that they need to welcome strangers, so they try to be a warm, open family. Some of them believe they have achieved this model, but few do achieve it. The key to turning this situation around lies in the congregation’s attitude toward the stranger. This is especially true of the attitude of those who plan and lead …

Furniture Manufacturing And Marketing In The ‘American Economic Transition, Steven H. Bullard

Faculty Publications

The Office of Technology Assessment recently prepared a 500 page report titled Technology and the American Economic Transition, Choices for the Future. OTA sees four major factors that are resulting in "economic transition" factors that will continue to transform the U.S. economy during the next 20 years: new technologies, new challenges from abroad, new resource constraints, and new values and tastes in U.S. consumer and labor markets.

New technologies, particularly in collecting and handling information, are expected to have long-term, pervasive economic and social impacts comparable to past U.S. economic transformations from major technologies such as automobiles and railroads. New …

Potential For Biological Control Of Dendroctonus And Ips Bark Beetles, David Kulhavy, Mitchel C. Miller

Faculty Publications

"The evolution of olfactory communication in bade beetles brought with it the parallel or coevolution of kairomonal systems in the natural enemy complexes. Entomophagous insects developed olfactory receptors and behavioral patterns responsive to insect and host-produced volatiles in the ecosystems of bark beetles. The phenomenon has both positive and negative implications for efforts to employ natural enemies in pest management."
