Intensive Voice Treatment In Parkinson Disease: Laryngostroboscopic Findings, Christopher Dromey, Marshall E. Smith, Lorraine Olson Ramig, Kathe S. Perez, Raz Samandari

Faculty Publications

Summary: As part of ongoing research to investigate and document the efficacy of intensive voice therapy to improve functional communication in patients with idiopathic Parkinson disease, 45 patients were enrolled in a controlled, randomized, prospective study. Pre- to posttreatment comparisons are presented here on 22 of those patients who underwent laryngeal imaging examination. Of the 22 patients, 13 patients received intensive therapy aimed at increasing vocal and respiratory effort (VR), whereas nine received intensive therapy aimed at increasing respiratory effort (R) only. All patients had a pretreatment evaluation that included two (but sometimes only one) voice recordings and an otolaryngologic …

Mentors: Keys To Survival And Growth, Chris Crowe

Faculty Publications

My diploma proved I knew English; my teaching certificate proved I knew how to teach it. Armed only with these and a head filled with idealistic visions of myself as the next Mr. Chips, I landed my first teaching job. As a mid-year graduate, I was lucky to flnd any high school job, so I jumped at the first, and only, offer. I started work on January 3, taking over for an established teacher who at mid-term had gone on permanent disability leave.

New Optical Cell Design For Laser Flash Photolysis Studies In Supercritical Fluids, Steven R. Goates, Milton L. Lee, Qin Ji, Edward M. Eyring, Rudi Van Eldik, Kedika Bal Reddy

Faculty Publications

A high-pressure optical cell has been designed that achieves an effective separation between the chemical sample and the pressurizing medium and system. This design limits possible sample contamination and catalytic effects under supercritical fluid sample conditions. Laser flash photolysis experiments were carried out on molybdenum hexacarbonyl dissolved in supercritical CO2. The thermal ring closure reaction of the species Mo(CO)5L, where L is 2,2- bipyridine was found to proceed at rates comparable to those measured previously in liquid benzene or toluene. Much larger activation volumes were found for the reaction in supercritical CO2 than in liquid toluene.

Slow Motion In One-Dimensional Cahn-Morral Systems, Christopher P. Grant

Faculty Publications

In this paper we study one-dimensional Cahn-Morral systems, which are the multicomponent analogues of the Cahn-Hilliard model for phase separation and coarsening in binary mixtures. In particular, we examine solutions that start with initial data close to the preferred phases except at finitely many transition points where the data has sharp transition layers, and we show that such solutions may evolve exponentially slowly; i.e., if ε is the interaction length then there exists a constant C such that in exp(C/ε) units of time the change in such a solution is o(1). This corresponds to extremely slow coarsening of a multicomponent …

The Impact Of Dap Inservice Training Of The Beliefs And Practices Of Kindergarten Teachers, Julia H. Haupt, Jean M. Larsen, Clyde C. Robinson, Craig H. Hart

Faculty Publications

As teacher training institutions have adopted the NAEYC standards for developmentally appropriate practices (hereinafter DAP) (Bredekamp, 1987) and have begun to routinely train pre-service teachers in these principles the need for student teaching experiences which reflect this orientation has become a priority for many teacher educators. However, locating developmentally appropriate placement settings, particularly when large numbers of student teachers are being trained simultaneously, may be difficult in some localities.

Waterjet Cutting Of Cross-Linked Glass, Fang Yuan, John A. Johnson, David D. Allred, Robert H. Todd

Faculty Publications

The cutting of cross-linked glasses such as silica and Corning 7059 can be difficult. We conducted an experimental study to determine the feasibility of using a high-speed waterjet to cut thin Corning 7095 glass. Cutting using either pure de-ionized high pressure water at 380 MPa (55 000 psi) or de-ionized water with entrained garnet abrasive was studied. The roughness of the cut surfaces was measured and compared. Photomicrographs were taken of glass examples cut at different traversing rates with pure water and with the abrasive entrained waterjet. Comparative studies of cutting with and without the entrained abrasive material showed that …

Overcoming "Stigmas": Lesbian And Gay Districts And Black Electoral Empowerment, Darren Rosenblum

Faculty Publications

(Excerpt)

In the United States, historically, members of racial and sexual minority groups have been prevented from effectively participating in governmental decisionmaking because the political districting system denies them adequate representation in the political process. Following the 1990 census, blacks, in particular, saw significant gains in their political representation as a result of redistricting, only to suffer a sharp reduction of their voting rights with the U.S. Supreme Court's decisions in the Shaw and Miller cases. Whereas voting rights litigation once explored ways to prevent minority vote dilution, today's jurisprudence focuses on the ramifications of the "stigma" faced by blacks …

The Ties That Bind: An Interdisciplinary Analysis Of Gender, Ethnicity, And The Practice Of Law, Rosemary C. Salomone

Faculty Publications

(Excerpt)

Over the past decade, fueled in part by Carol Gilligan's controversial book, In a Different Voice, both feminists and scholars of color have critically examined the law from the "outsiders'" perspective. Stretching methodological bounds, this interrelated body of scholarship has utilized narrative form to question the gender and racial implications of social practices and legal rules and to demonstrate the useful purpose that stories serve as a means of including marginalized groups in law's evolution and reform. Women scholars of color have carved out a particular role in this debate, criticizing feminism's categorical conceptualization of "woman." They have advanced …

The Evolution Of American Probate Courts And Emerging Standards To Guide Their Progress, Thomas L. Hafemeister, Paula Hannaford-Agor

Faculty Publications

Courts with probate jurisdiction are an excellent example of the evolu­tion of American courts. Despite the fact that they are direct descendants of the English judicial system, the structure, jurisdiction, and procedures of the probate courts assumed a uniquely American flavor soon after their initial establishment in the colonies. From the beginning, American probate courts have shown considerable diversity from state to state. State courts exercising probate jurisdiction have continued to evolve over time in response to the various demands placed upon them. This article describes the historical evolution of American courts exer­cising jurisdiction over probate matters, with specific attention …

A Preliminary Mass Balance Model Of Primary Productivity And Dissolved Oxygen In The Mississippi River Plume/Inner Gulf Shelf Region, Victor J. Bierman Jr., Scott C. Hinz, William J. Wiseman Jr., Nancy N. Rabalais, R. Eugene Turner

Faculty Publications

A deterministic, mass balance model for phytoplankton, nutrients, and dissolved oxygen was applied to the Mississippi River Plume/Inner Gulf Shelf (MRP/IGS) region. The model was calibrated to a comprehensive set of field data collected during July 1990 at over 200 sampling stations in the northern Gulf of Mexico. The spatial domain of the model is represented by a three-dimensional, 21-segment water-column .grid extending from the Mississippi River Delta west to the Louisiana-Texas border, and from the shoreline seaward to the 30-60 m bathymetric contours. Diagnostic analyses and numerical experiments were conducted with the calibrated model to better understand the environmental …

Comparison Of Continuous Records Of Near-Bottom Dissolved Oxygen From The Hypoxia Zone Along The Louisiana Coast, Nancy N. Rabalais, William J. Wiseman, R. Eugene Turner

Faculty Publications

Oxygen depletion is a seasonally dominant feature of the lower water column on the highly-stratified, riverine-influenced continental shelf of Louisiana. The areal extent of hypoxia (bottom waters ≤2 mg l−1 dissolved oxygen) in mid-summer may encompass up to 9,500 km2, from the Mississippi River delta to the upper Texas coast, with the spatial configuration of the zone varying interannually. We placed two continuously recording oxygen meters (Endeco 1184) within 1 m of the seabed in 20-m water depth at two locations 77 km apart where we previously documented midsummer bottom water hypoxia. The oxygen meters recorded considerably different oxygen conditions …

Denitrification, Nutrient Regeneration And Carbon Mineralization In Sediments Of Galveston Bay, Texas, Usa, Andrew R. Zimmerman, Ronald Benner

Faculty Publications

Rates of benthic denitrification, oxygen consumption and nutrient regeneration were measured during winter, spring and summer in Galveston Bay (Texas, USA) sediments. Denitrification ranged from 0 to 47 µmol N₂ m^-2 h^-1 with maximal rates generally occurring in the summer and the upper estuary. Oxygen consumption rates ranged from 38 µmol O₂ m^-2 h^-1 in the winter to 353 µmol O₂ m^-2 h^-1 in the summer and were correlated with denitrification rates. Variations in bay water temperature accounted for 52 % of the variability associated with denitrification rates whereas only 28% …

The Nuts & Bolts Of Cooperative Learning In Engineering, Nikos J. Mourtos

Faculty Publications

A great number of engineering students work alone. But in industry, teamwork is required most of the time. Incorporating Cooperative Learning (CL) into an engineering program gives students an opportunity to practice problem solving and communication skills in a "simulated" professional environment. The paper briefly discusses the motivation behind using CL in engineering courses. Then, the essential elements to make CL successful in the classroom are examined and examples of how these elements have been incorporated into engineering courses taught by the author are given. Problems that have been encountered along with possible fixes are also mentioned.

Semiclassical Quantization Of A Nonintegrable System: Pushing The Fourier Method Into The Chaotic Regime, Karl Sohlberg, Randall B. Shirts

Faculty Publications

Semiclassical Einstein–Brillouin–Keller (EBK) quantization of the nonintegrable Hénon–Heiles Hamiltonian succeeds using the Fourier transform method of Martens and Ezra. Two innovations are required for this success: (1) the use of tunneling corrected quantizing actions obtained from an approximate, one-dimensional Hamiltonian and (2) exploitation of intermediate-time approximate quasiperiodicity or "vague tori'' wherein the Fourier transform of chaotic motion over 10–100 vibrational periods allows the determination of frequencies and amplitudes which approximate motion during the time interval. Approximate tori, actions, and EBK energy levels are then straightforward. We use an interpolation method to smooth over small resonance zones that are not expected …

Ultrasonic Enhancement Of Antibiotic Action On Gram-Negative Bacteria, William G. Pitt, Michael O. Mcbride, Jared K. Lunceford, Randall J. Roper, Richard D. Sagers

Faculty Publications

The effect of gentamicin upon planktonic cultures of Pseudomonas aeruginosa, Escherichia coli, Staphylococcus epidermidis, and Staphylococcus aureus was measured with and without application of 67-kHz ultrasonic stimulation. The ultrasound was applied at levels that had no inhibitory or bactericidal activity against the bacteria. Measurements of the MIC and bactericidal activity of gentamicin against planktonic cultures of P. aeruginosa and E. coli demonstrated that simultaneous application of 67-kHz ultrasound enhanced the effectiveness of the antibiotic. A synergistic effect was observed and bacterial viability was reduced several orders of magnitude when gentamicin concentrations and ultrasonic levels which by themselves did not reduce …

A Vlsi Implementation Of A Parallel, Self-Organizing Learning Model, Tony R. Martinez, George L. Rudolph, Linton G. Salmon, Matthew G. Stout

Faculty Publications

This paper presents a VLSI implementation of the Priority Adaptive Self-organizing Concurrent System (PASOCS) learning model that is built using a multi-chip module (MCM) substrate. Many current hardware implementations of neural network learning models are direct implementations of classical neural network structures - a large number of sample computing nodes connected by a dense number of weighted links. PASOCS is one of a class of ASOCS (Adaptive Self-Organizing Concurrent System) connectionist models whose overall goal is the same as classical neural networks models, but whose functional mechanisms differ significantly. This model has potential application in areas such as pattern recognition, …

Dynamic Economic Analyses Of Selected Provisions Of Corporate Law: The Absolute Delegation Rule, Disclosure Of Intermediate Estimates And Ipo Pricing, Royce De R. Barondes

Faculty Publications

This Article examines three separate aspects of the relationships between corporations and their securityholders from a dynamic economic perspective: (i) the feasibility of permitting shareholders to participate in the management of their corporations through the exercise of voting rights, (ii) Rule 3b-6, the safe harbor for projections (the Safe Harbor)8 under the Securities Exchange Act of 1934 (the 1934 Act),9 and (iii) the extraordinary returns available from investing in initial public offerings (IPO's). Three particular dynamic aspects are implicated in these situations.

Contextual Interference Effects In The Acquisition And Retention Of Motor Tasks By Individuals With Mild Mental Handicaps, William J. Vincent, Mary A. Painter, Kathleen B. Inman

Faculty Publications

The effects of contextual interference on motor skill acquisition and retention were examined in 24 subjects (mean age 13.9 years) with mild mental retardation and 24 chronologically age-matched subjects (mean age 13.11 years) with no disabilities. Subjects from each group were assigned randomly to either a blocked or a random practice schedule. All subjects performed 15 practice trials for each of three different beanbag throwing tasks, 45 trials total. Following a 10-min filled retention interval, 2 trials of each throw (6 total) were performed in a random order by all subjects. Accuracy scores were measured as absolute error from the …
