So What's New In The New Basals? A Focus On First Grade, James V. Hoffman, Sarah J. Mccarthey, Judy A. Abbott, Cheryl Christian, Laura Corman, Catherine Curry, Mark Dressman, Bonnie Elliot, Debra Maherne, Debra Stahle Jan 1994

So What's New In The New Basals? A Focus On First Grade, James V. Hoffman, Sarah J. Mccarthey, Judy A. Abbott, Cheryl Christian, Laura Corman, Catherine Curry, Mark Dressman, Bonnie Elliot, Debra Maherne, Debra Stahle

Faculty Publications

The authors examine the first grade materials in five new basal programs submitted for the 1993 Texas state adoption. These series are compared with program materials currently in use in the state (Copyright 1986/1987). The analysis focuses on features of the pupil texts(e.g., total number of words, number of unique words, readability levels, literary quality) and features of the teachers' editions (e.g., program design, organization, tone). Results of the analysis indicate substantial changes in the more recent series.The findings are interpreted in terms of historical trends as well as recent developments in the literature-based and whole language movements.Implications for future …

A Probabilistic Model For Avcs Longitudinal Collision/Safety Analysis, Jacob Tsao, Randolph Hall Jan 1994

A Probabilistic Model For Avcs Longitudinal Collision/Safety Analysis, Jacob Tsao, Randolph Hall

Faculty Publications

This paper develops a probabilistic model for analyzing longitudinal collision/safety between an abruptly decelerating vehicle and its immediate follower. The input parameters are the length of the gap between the two vehicles, their common speed prior to the failure, the reaction delay of the following vehicle and a bivariate distribution for the two deceleration rates. The output includes the probability of a collision and the probability distribution of the relative speed at collision time We use this model to compare the safety consequences associated with the platooning and “free-agent” longitudinal-separation rules. We also demonstrate that the free-agent rule implemented with …

Block Qpsk Modulation Codes With Two Levels Of Error Protection, Robert H. Morelos-Zaragoza, Shu Lin Jan 1994

Block Qpsk Modulation Codes With Two Levels Of Error Protection, Robert H. Morelos-Zaragoza, Shu Lin

Faculty Publications

A class of block QPSK modulation codes for unequal error protection (UEP) is presented. These codes are particularly suitable either for broadcast channels or for communication systems where parts of the information messages are more important than others. An example of the latter is coded speech transmission. Not much is known on the application of block UEP codes in combined coding and modulation schemes. We exhibit a method to combine binary linear UEP (LUEP) block codes of even length, using a Gray mapping, with a QPSK signal set to construct efficient block QPSK modulation codes with nonuniform error protection capabilities …

Constraints On Initial Ahs Deployment And The Concept Definition Of A Shuttle Service For Ahs Debut, Jacob Tsao Jan 1994

Constraints On Initial Ahs Deployment And The Concept Definition Of A Shuttle Service For Ahs Debut, Jacob Tsao

Faculty Publications

Highway automation and its evolution involve a multitude of systems issues. Particularly important and difficult in defining a deployment sequence is the very first step, i.e. the first user service involving fully automated freeway driving. However, this importance and the difficulty imply that many factors may severely constrain the initial deployment. After discussing the paramount importance of initial AHS deployment, this paper points out major high-level issues and constraints. Any realistic deployment strategy must take into consideration gradual technology maturation, introduction of new driver role and diminishing conventional driver role for automated driving, high cost of early-generation automation-equipped vehicles, gradual …

Comparison Of Dietary Overlap Between Allopatric And Sympatric Geckos, Paul D. Klawinski, R. Kathryn Vaughan, Daniel Saenz, William Godwin Jan 1994

Comparison Of Dietary Overlap Between Allopatric And Sympatric Geckos, Paul D. Klawinski, R. Kathryn Vaughan, Daniel Saenz, William Godwin

Faculty Publications

Two gecko species, Hemidactylus turcicus and Cyrtopodion scabrum, have been introduced into the Port of Galveston, Texas. While H. turcicus has been established for a longer period of time, the relatively recent introduction of C. scabrum near the entrance of the Port has apparently led to the displacement of H. turcicus in that area. This has resulted in a distribution in which the two populations’ are largely allopatric except for a narrow band of sympatry at the periphery of each of their ranges. We examined stomach contents of both species in allopatry and sympatry in order to determine if …

The Eleventh Circuit’S First Decade Contribution To The Law Of The Nation, 1981-1991, Thomas E. Baker Jan 1994

The Eleventh Circuit’S First Decade Contribution To The Law Of The Nation, 1981-1991, Thomas E. Baker

Faculty Publications

Likewise, the task of commentary is difficult. The period covered here-the first decade of the Eleventh Circuit-represents, quite literally and figuratively, the formative era of the court. Indeed, the volume of decisions and their variety are qualities that ought to humble, if not intimidate, most commentators. Justice Holmes once observed that a common law court could be expected to replicate the entire corpus juris in the space of a single generation. The Eleventh Circuit did this consciously between 1981 and 1991. In Bonner v. City of Prichard, the inaugural en banc court held that the new court-just cleaved from the …

A Performance Evaluation Of Edging And Trimming Operations In U.S. Hardwood Sawmills, Tony El-Radi, Steven H. Bullard, Philip Steele Jan 1994

A Performance Evaluation Of Edging And Trimming Operations In U.S. Hardwood Sawmills, Tony El-Radi, Steven H. Bullard, Philip Steele

Faculty Publications

Edger and trimmer operators must make constant decisions in short time periods on the amount of materials to remove from boards produced in the sawmill. Their decisions directly affect the total volume, grade, and value of the boards, and they therefore directly affect the total value of lumber produced. In recent years, many softwood sawmills have installed computer controlled edgers and trimmers with scanners and optimizers to achieve higher recovery rates. Before similar, relatively expensive, technologies can be seriously evaluated for the hardwood industry, however, the current performance of edging and ·trimming operations must be known. Using a sample of …

Direct Simulation Monte Carlo For Thin Film Bearings, Alejandro Garcia, B. Alder, F. J. Alexander Jan 1994

Direct Simulation Monte Carlo For Thin Film Bearings, Alejandro Garcia, B. Alder, F. J. Alexander

Faculty Publications

The direct simulation Monte Carlo (DSMC) scheme is used to study the gas flow under a read/write head positioned nanometers above a moving disk drive platter (the slider bearing problem). In most cases, impressive agreement is found between the particle-based simulation and numerical solutions of the continuum hydrodynamic Reynolds equation which has been corrected for slip. However, at very high platter speeds the gas is far from equilibrium, and the load capacity for the slider bearing cannot be accurately computed from the hydrodynamic pressure.

The Bespeaks Caution Doctrine: Revisiting The Application Of Federal Securities Law To Opinions And Estimates, Royce De R. Barondes Jan 1994

The Bespeaks Caution Doctrine: Revisiting The Application Of Federal Securities Law To Opinions And Estimates, Royce De R. Barondes

Faculty Publications

Disclosure of estimates and opinions, which are often referred to as ‘soft information,‘ has presented a number of difficult issues to courts, the Securities and Exchange Commission (SEC) and companies issuing offering materials or required to file periodic reports with the SEC. Although this type of information often consists of projections, historical financial statements also include this type of information to varying degrees. For example, a bank's statement of financial position requires specification of loan loss reserves and is therefore dependent on an assessment of future events (the timing and extent of repayment). Similarly, determination of the timing of a …

Evidence For A Role Of Β‐1,3‐Glucanase In Dicot Seed Germination, Regina Vögeli‐Lange, Corinne Fründt, Craig M. Hart, Roland Beffa, Ferenc Nagy, Frederick Meins Jan 1994

Evidence For A Role Of Β‐1,3‐Glucanase In Dicot Seed Germination, Regina Vögeli‐Lange, Corinne Fründt, Craig M. Hart, Roland Beffa, Ferenc Nagy, Frederick Meins

Faculty Publications

Class I β‐1,3‐glucanases are antifungal vacuolar proteins implicated in plant defense that show developmental, hormonal, and pathogenesis‐related regulation. The expression was studied in germinating tobacco seeds of a chimeric β‐glucuronidase (GUS) reporter gene fused to 1.6 kb of the 5′ flanking sequence of the tobacco class I β‐1,3‐glucanase B (GLB) promoter. Histological staining for GUS activity showed that expression of the GLB promoter is highly localized in a specific zone of the endosperm in germinating seeds. The temporal and spatial patterns of GUS and β‐1,3‐glucanase activity found, suggest a novel function for class I β‐1,3‐glucanases during seed germination in a …

Aerosol Matrix-Assisted Laser Desorption Ionization Mass Spectrometry, Kermit K. Murray, David H. Russell Jan 1994

Aerosol Matrix-Assisted Laser Desorption Ionization Mass Spectrometry, Kermit K. Murray, David H. Russell

Faculty Publications

A new method of liquid sample introduction for a time-of-flight mass spectrometer (TOF-MS) has been developed by applying the method of matrix-assisted laser desorption ionization to aerosols. Analyte biomolecules are dissolved in a methanol solvent along with a UVabsorbing matrix and formed into an aerosol with a pneumatic nebulizer. The aerosol particles are dried in a heated skimmer tube before ionization by pulsed 355-nm UV laser radiation. Mass analysis is achieved in a linear TOF-MS. Results for the ionization of bovine insulin (5733.5 Mw) are reported. © 1994 American Society for Mass Spectrometry.

Biological And Genetic Characterization Of A Hemagglutinating Coronavirus Isolated From A Diarrhoeic Child, X. M. Zhang, W. Herbst, K. G. Kousoulas, J. Storz

Faculty Publications

The coronavirus strain HECV‐4408 was isolated from diarrhea fluid of a 6‐year‐old child with acute diarrhea and propagated in human rectal tumor (HRT‐18) cells. Electron microscopy revealed coronavirus particles in the diarrhea fluid sample and the infected HRT‐18 cell cultures. This virus possessed hemagglutinating and acetylesterase activities and caused cytopathic effects in HRT‐18 cells but not in MDBK, GBK and FE cells. One of four S‐specific monoclonal antibodies reacted in Western blots with HECV‐4408, BCV‐L9 and BCV‐LY138 but not with HCV‐OC43, and two reacted with BCV‐L9 but not with HECV‐4408, BCV‐LY138 and HCV‐OC43. One S‐specific and two N‐specific monoclonal antibodies …

Bleach cleansing of injection equipment has been recommended to reduce the risk of human immunodeficiency virus (HIV) transmission associated with the reuse of injection equipment by injecting drug users (IDUs). We evaluated the recall and performance of the most commonly recommended bleach cleansing procedure of two complete fillings of the syringe with bleach, followed by two complete fillings with rinse water, and not putting used bleach and water back into source containers. IDUs were taught this procedure on enrollment in an HIV prevention demonstration project in Dade County, Florida. During follow-up session 6-12 months after initial training, the knowledge and …

Maintaining Order In The Post-Strike Workplace: Employee Expression And The Scope Of Section 7, Lyrissa Lidsky Jan 1994

Maintaining Order In The Post-Strike Workplace: Employee Expression And The Scope Of Section 7, Lyrissa Lidsky

Faculty Publications

In the aftermath of a typical strike, management often seeks to restore order to the workplace by imposing restrictions on employee expression. Although in principle employee expression is protected by section 7 of the National Labor Relations Act, courts, relying on outdated notions of workplace organization, often accept ad hoc management justifications for restrictions on employee expression. The author argues that after a strike, it is crucial for employees to be able to express their grievances or vent their frustrations at exactly the same time that employers feel it necessary to restrict expression as a way of re-imposing order in …

Energy Trade And The National Security Exception To The Gatt, Donald N. Zillman Jan 1994

Energy Trade And The National Security Exception To The Gatt, Donald N. Zillman

Faculty Publications

Three topics combine in this paper: international trade, national security, and energy. The specific focus of the paper is the General Agreement on Tariffs and Trade (GATT) and the "essential security interests" exception contained in Article XXI. The provisions of the GATT set out the structure of a system to encourage international trade by reducing tariffs and other trade barriers. More broadly, many aspects of international trade in energy have developed outside the structure of GATT or with the implied assumption that Article XXI or another GATT exception would take them out of normal GATT arrangements. National security matters have …

Urban Revitalization And Community Finance: An Introduction, Peter R. Pitegoff Jan 1994

Urban Revitalization And Community Finance: An Introduction, Peter R. Pitegoff

Faculty Publications

"In his 1933 poem Burn the Cities, Nathanael West, the iconoclastic American novelist and urban radical, portrays the city as a focal point of discontent and of anguish for the world's predicament.2 From Jerusalem to Paris and finally to London, the poem winds through distressing urban imagery with scant opportunity for escape. The implicit modicum of hope is an overthrow of the present order. From older cities abroad, West imports an apocalyptic vision of cities at home."

Faculty Publications

Diffuse galactic continuum γ-ray emission in the 0.75-30 MeV range from the inner Galaxy has been studied using data from COMPTEL on the Compton Gamma-Ray Observatory. Observations of the inner Galaxy from the Sky Survey have been used. The imaging properties of COMPTEL enable spatial analysis of the γ-ray distribution using model fitting. A model based on atomic and molecular gas distributions in the Galaxy has been used to derive the emissivity spectrum of the γ-ray emission and this spectrum is compared with theoretical estimates of bremsstrahlung emission from cosmic-ray electrons.

Primary Decomposition Of Torsion R[X]-Modules, William A. Adkins Jan 1994

Primary Decomposition Of Torsion R[X]-Modules, William A. Adkins

Faculty Publications

This paper is concerned with studying hereditary properties of primary decompositions of torsion R[X]-modules M which are torsion free as R-modules. Specifically, if an R[X]-submodule of M is pure as an R-submodule, then the primary decomposition of M determines a primary decomposition of the submodule. This is a generalization of the classical fact from linear algebra that a diagonalizable linear transformation on a vector space restricts to a diagonalizablc linear transformation of any invariant subspace. Additionally, primary decompositions are considered under direct sums and tensor product. © 1994, Hindawi Publishing Corporation. All rights reserved.

Chromosome And Sperm Size Of Holsteins With And Without Bovine Leukocyte Adhesion Deficiency, H. C. Steinholt, J. E. Chandler, R. A. Baron, R. W. Adkinson

Faculty Publications

The objective was to evaluate bull differences in chromosomal and spermatozoal areas related to the occurrence of the bovine leukocyte adhesion deficiency syndrome. Lymphocyte chromosomes from 30 Holstein bulls and 2 Holstein heifers were measured using image analysis and computer-enhanced video-microscopy. Spermatozoal head areas from 29 of the 30 bulls were measured. Autosomal rank was based on decreasing area. Average total autosomal areas were not the same across bulls. One group of bulls had significantly smaller average chromosomal areas than the others; this group carried bovine leukocyte adhesion deficiency syndrome. Area measures of spermatozoal heads showed that bulls with bovine …
