Regional Specialization In Communal Agriculture: The Shakers, 1850- 1880, John E. Murray, Metin M. Cosgel

Economics Working Papers

When the Shakers established communal farms in the Ohio Valley, they encountered a new agricultural environment that was substantially different from the familiar soils, climates, and markets of New England and the Hudson Valley. The ways in which their response to these new conditions differed by region has not been well documented. We examine patterns of specialization among the Shakers using the manuscript schedules of the federal Agricultural Censuses from 1850 through 1880. For each Shaker unit, we also recorded a random sample of five farms in the same township (or all available farms if there were fewer than five). …

Productivity Of A Commune: The Shakers, 1850-80, Metin M. Cosgel, John E. Murray

Economics Working Papers

How does the productivity of a commune compare with that of a conventional firm? This paper addresses this question quantitatively by focusing on the history of a religious commune called the United Society of Believers, better known as the Shakers. We utilize the information recorded in the enumeration schedules of the US Manufacturing and Agriculture Censuses, available for the period between 1850 to 1880, to estimate the productivities of Shaker shops and farms. From the same data source, we also construct random samples of other shops and farms and estimate their productivities for comparison with the Shakers. Our results provide …

Sliding Mode For User Equilibrium Dynamic Traffic Routing Control, Pushkin Kachroo, Kaan Ozbay

Electrical & Computer Engineering Faculty Research

Presents a solution to the user equilibrium dynamic traffic routing (DTR) problem for a point diversion case using feedback control methodology. The sliding mode control technique which is a robust control methodology applicable to nonlinear systems in canonical form is employed to solve the user equilibrium DTR problem. The canonical form for this problem is obtained by using a feedback linearization technique, and the uncertainties of the system are countered by using the sliding mode principle. Simulation results show promising results.

Phase Diagrams Of A Binary Smectic-A Mixture, Hao-Wen Chiu, Thein Kyu

College of Polymer Science and Polymer Engineering

A variety of smectic phase diagrams involving smectic-isotropic and smectic-nematic-isotropic transitions have been calculated based on a combination of Flory-Huggins (FH) theory for isotropic mixing and Maier-Saupe-McMillan (MSM) theory for smectic-A ordering of liquid crystals (LC). To describe the mesophase transitions, two nematic order parameters and two smectic order parameters have been coupled through the normalized orientation distribution and partition functions. Flory-Huggins interaction parameter (chi) for isotropic mixing and the coupling term involving the nematic interaction parameter (nu) and the McMillan smectic interaction parameter (alpha) for phase transitions of liquid crystals have been incorporated in the calculation. The predictive capability …

Socioeconomic Status And Health In Blacks And Whites: The Problem Of Residual Confounding And The Resiliency Of Race, Jay S. Kaufman, Richard S. Cooper, Daniel L. Mcgee

Faculty Publications

A large number of epidemiologic studies have focused on racial/ethnic differences, particularly between blacks and whites. Because health endpoints and racial categorizations are associated with socioeconomic status, investigator, generally adjust for socioeconomic indicators. The intention is usually to control for confounding, thereby making groups comparable and excluding socioeconomic status as an alternative explanation to hypotheses of innate physiologic differences. A threat to the validity of these analyses is therefore the presence of residual confounding. We identify four potential sources of residual confounding in this analytical design: categorization of socioeconomic status variables, measurement error in socioeconomic indicators, use of aggregated socioeconomic …

Robotic Tcf And Rigid-Body Calibration Methods, Edward Red, Xuguang Wang

Faculty Publications

For off-line programming to work, systematic methods must be developed to account for non-ideal performance of the parts and devices in the manufacturing cell. Although much of the literature focuses on robot inaccuracy, this paper considers practical methods for the tool control frame (TCF) calibration and rigid-body compensation required to close the inverse kinematics loop for target driven tasks.

Occupational Therapy's Link To Vocational Reeducation, 1910-1925., Sharon A. Gutman

Department of Occupational Therapy Faculty Papers

The development of occupational therapy is rooted in early 20th century medical reform. During the early 1910s, several members of the medical profession, human service workers, and the larger American society were increasingly disturbed by medical practices that did not consider the individual's personal experience of disability. Occupational therapy was developed, in part, out of this desire to provide persons with treatment that helped them to function in their communities despite their disability. Early occupational therapy leaders envisioned the fledgling profession as a societal service capable of assisting persons with disabilities to return to both work and community life. Vocational …

Wear, Design And Enjoy Clothing, Seung Baik

Theses

Many artists choose to combine metal and textile to execute their works. Metal elements are sewn, woven, and crocheted into garments, sculpture, ornament, or decoration because it fastens directly to fabric to make a richly creative and decorative effect. Also, the qualities of metal provide structural stiffness, weight, and light (reflection) to the fabric. I explored different ways of integrating metal and fiber into the fabric of woven yarn structures. "Using textile techniques in metal does not constitute a movement or a style."1 However, treating metal like fiber is an intriguing concept with flexible possibilities for the two different materials.

Simulating Ozone Effects On Forest Productivity: Interactions Among Leaf‐, Canopy‐, And Stand‐Level Processes, Scott V. Ollinger, John D. Aber, Peter B. Reich

Faculty Publications

Ozone pollution in the lower atmosphere is known to have adverse effects on forest vegetation, but the degree to which mature forests are impacted has been very difficult to assess directly. In this study, we combined leaf‐level ozone response data from independent ozone fumigation studies with a forest ecosystem model in order simulate the effects of ambient ozone on mature hardwood forests. Reductions in leaf carbon gain were determined as a linear function of ozone flux to the leaf interior, calculated as the product of ozone concentration and leaf stomatal conductance. This relationship was applied to individual canopy layers within …

Ccd Speckle Observations Of Binary Stars From The Southern Hemisphere, Elliott P. Horch, Zoran Ninkov, Robert W. Slawson

Articles

We present 119 position angle and separation measures of 86 double stars observed by way of speckle interferometry with the University of Toronto Southern Observatory 60 cm telescope at Las Campanas, Chile. Speckle interferograms are recorded with a bare (unintensified) front-illuminated CCD in a fast subarray-readout mode. Position angles and separations are determined by a weighted least-squares fitting algorithm applied to the binary power spectra, and the 180-degree ambiguity in the position angle inherent in this approach is resolved by bispectral analysis. In this configuration the 60 cm telescope exhibits near-diffraction-limited performance. Initial results indicate that our separation measures have …

A 'New' Cultural Geography? Debates About Invention And Reinvention, Lily Kong

Research Collection School of Social Sciences

The Remaking Human Geography series critically reviews key journal articles, published in the last ten years, which have become 'citation classics'. Contributors to the series report on the academic debate which followed publication of the original article and assess why the article proved so influential. In this case Kong reviews an article on cultural geography by Cosgrove and Jackson (first published in Area in 1987). Peter Jackson also offers his thoughts on the 'cultural turn' and on future directions in this research field.

Radiation Imaging Operators Applied To The Detection Of Velocity And Density Contrast Boundaries, Md. Ishfaqur Raza, Richard E. Dubroff, James L. Drewniak

Electrical and Computer Engineering Faculty Research & Creative Works

A procedure for imaging interfaces formed by simultaneous density and velocity contrasts in acoustic media is described. The procedure is based on the properties of radiation imaging operators - a class of linear differential operators parametrically dependent on the acoustic properties of the media. An example of this procedure is demonstrated through the use of numerical simulation. Results, in the form of interface images, are shown, assuming the bulk acoustic characteristics (velocity and density) on both sides of the interface are known.

An Experimental Procedure For Characterizing Interconnects To The Dc Power Bus On A Multilayer Printed Circuit Board, Hao Shi, James L. Drewniak, Todd H. Hubing, Thomas Van Doren, Fei Sha

Electrical and Computer Engineering Faculty Research & Creative Works

The effectiveness of dc power-bus decoupling is impacted by the inductance associated with interconnect vias in printed circuit boards (PCB's). Adequate characterization of these interconnects is necessary to facilitate modeling and simulation, and to assess the effectiveness of added decoupling. In this study, a measurement procedure is presented for determining the series inductance and resistance of an interconnect with a network analyzer. The validity and limitations of the procedure are discussed. Experimental results of interconnect parameters on an 8 × 10 in ten-layer test-board corroborate those measured with a precision impedance analyzer. The measured interconnect values are used to simulate …

Nato Enlargement And The Baltic States: What Can The Great Powers Do?, Stephen J. Blank Dr.

Books, Monographs & Collaborative Studies

NATO's enlargement has brought it to the borders of the Baltic states who covet membership in NATO. However, admitting them into NATO is one of the most difficult problems for the Alliance because of Russia's unconditional opposition to such action and because of NATO's own internal divisions on this issue. Nonetheless, a new regime or system of security for the entire Baltic region must now be on the U.S. and European agenda. The key players in such a process are Russia, Germany, and the United States. Their actions will determine the limits of the possible in constructing Baltic security for …

The Association Of Hla-Drb Genes And The Shared Epitope With Rheumatoid Arthritis In Pakistan, K Hameed, S Bowman, E Kondeatis, R Vaughan, T Gibson

Section of Internal Medicine

The association of particular HLA-DR alleles and the shared epitope with rheumatoid arthritis (RA) is now well established. The strength of these links varies between races. Furthermore, the proposition that the presence of the shared epitope is indicative of severe disease has been more difficult to sustain in non-Europeans. This study examines the frequency of HLA-DR and HLA-DRB1 amongst Pakistanis for the first time. Using the polymerase chain reaction (PCR) and sequence-specific oligonucleotide probes (PCR-SSOP) and primers (PCR-SSP), HLA-DR phenotype and genotype frequencies were ascertained in 86 RA hospital out-patients and 79 healthy controls matched for age, gender and ethnicity. …

Vic*: A Compiler For Virtual-Memory C*, Alex Colvin, Thomas H. Cormen

Computer Science Technical Reports

This paper describes the functionality of ViC*, a compiler for a variant of the data-parallel language C* with support for out-of-core data. The compiler translates C* programs with shapes declared outofcore, which describe parallel data stored on disk. The compiler output is a SPMD-style program in standard C with I/O and library calls added to efficiently access out-of-core parallel data. The ViC* compiler also applies several program transformations to improve out-of-core data layout and access.

Molecular Fluorescence At A Rough Surface: The Orientation Effects, P.T. Leung, W. L. Blacke

Physics Faculty Publications and Presentations

The problem of the dynamical interaction between an emitting dipole and a metallic grating surface is considered with particular interest in the effects due to different orientations of the dipole with respect to the substrate surface. Our previous perturbative theory is extended to treat both parallel and perpendicular dipoles and the results are applied to the study of modified fluorescence characteristics for admolecules in the vicinity of a rough metal surface modeled as a grating. Numerical results show that some of the characteristics are very sensitive to the molecular orientation and the one along the grating direction is manifested with …
