The gluon momentum density xg(x, Q2) of the proton was extracted at Q2 = 20 GeV2 for small values of x between 4 × 10-4 and 10-2 from the scaling violations of the proton structure function F2 measured recently by ZEUS in deep inelastic neutral current ep scattering at HERA. The extraction was performed in two ways. Firstly, using a global NLO fit to the ZEUS data on F2 at low x constrained by measurementsfrom NMC at larger x; and secondly using published approximate methods for the solution of the GLAP QCD evolution equations. Consistent results are obtained. A substantial …

Community Metabolism And Nutrient Cycling In The Mississippi River Plume: Evidence For Intense Nitrification At Intermediate Salinities, Joseph D. Pakulski, Ronald Benner, Rainer Amon, Brian Eadie, Terry Whitledge Feb 1995

Community Metabolism And Nutrient Cycling In The Mississippi River Plume: Evidence For Intense Nitrification At Intermediate Salinities, Joseph D. Pakulski, Ronald Benner, Rainer Amon, Brian Eadie, Terry Whitledge

Faculty Publications

Community respiration, net nutrient fluxes and heterotrophic bacterial production were investigated in the Mississippi River (USA) plume during May 1992 using dark bottle incubations of unfiltered water. Highest rates of community O2 consumption and dissolved inorganic carbon regeneration were observed at intermediate (10 to 27%0) plume salinities. Plume surface 02 consumption rates were 2- to 4-fold greater than rates reported previously during the summer and winter. Heterotrophic bacterial production ([3H]-leucine incorporation) was also highest at intermediate salinities and 2- to 4-fold greater than rates reported from other seasons. Net regeneration of NH4+ …

Historic Preservation And The Civil Rights Movement Of The 1950'S And 1960'S: Identifying, Preserving, And Interpreting The Architecture Of Liberation, Robert Weyeneth Feb 1995

Historic Preservation And The Civil Rights Movement Of The 1950'S And 1960'S: Identifying, Preserving, And Interpreting The Architecture Of Liberation, Robert Weyeneth

Faculty Publications

This report surveys the extent to which the civil rights movement of the 1950's and 1960's has been commemorated in the United States. It concludes that there are wide-ranging and imaginative efforts not only in the South but all over the counny that seek to identify, preserve, and interpret historic sites associated with the civil rights movement These efforts, however, have been hampered by the difficulties of commemorating chapters of history that are local, recellt, and controversial. These problems of selectivity are analyzed in order to facilitate incorporation of missing aspects of civil rights history into future heritage preservation projects. …

Faculty Publications

We investigate spectral evolution in 37 bright, long gamma-ray bursts observed with the BATSE spectroscopy detectors. High-resolution spectra are characterized by the energy of the peak of νFν, and the evolution of this quantity is examined relative to the emission intensity. In most cases it is found that this peak energy either rises with or slightly precedes major intensity increases and softens for the remainder of the pulse. Interpulse emission is generally harder early in the burst. For bursts with multiple intensity pulses, later spikes tend to be softer than earlier ones, indicating that the energy of the peak of …

Inclusive jet differential cross sections for the reaction ep → jet + X at Q2 below 4 GeV2 have been measured with the ZEUS detector at HERA using an integrated luminosity of 0.55 pb-1. These cross sections are given in the kinematic region 0.2 < y < 0.85, for jet pseudorapidities in the ep-laboratory range -1 < ηjet < 2 and refer to jets at the hadron level with a cone radius of one unit in the η - θ plane. These results correspond to quasi-real photoproduction at centre-of-mass energies in the range 130-270 GeV and, approximately, for jet pseudorapidities in the interval -3 < ηjet(λp CMS) < 0. These measurements cover a new kinematic regime of the partonic structure of the photon, at typical scales up to ∼300 GeV2 and photon fractional momenta down to xγ ∼ 10-2. Leading logarithm parton shower Monte Carlo calculations, which include both resolved and direct processes and use the predictions of currently available parametrisations of the photon parton distributions, describe in general the shape and magnitude of the measured ηjet and Etjet distributions. © 1995.

Reading Instruction In First-Grade Classrooms: Do Basals Control Teachers?, James V. Hoffman, Sarah J. Mccarthey, Debra Bayles, Debra Price, Bonnie Elliott, Mark Dressman, Judy Abbott

Faculty Publications

This study describes first-grade teachers beliefs and practices about reading instruction. Drawing from interview and observational data, 16 teachers from four districts were placed on a continuum from skills-based to literature-based in relationship to their use of the basal. Only 2 teachers were found to rely solely on the basal, while 3 teachers enhanced the basal with literature, and 4 teachers used only literature in their reading instruction. Six teachers enhanced their basal use with additional skills and 1 teacher relied on skills only in her reading instruction. This diversity' of teaching beliefs and practices was corroborated by questionnaire data …

Transactional Criticism And Aesthetic Literary Experiences: Examining Complex Responses In Light Of The Teacher's Purpose, Joyce E. Many, Jacqueline K. Gerla, Donna L. Wiseman, Linda Ellis Jan 1995

Transactional Criticism And Aesthetic Literary Experiences: Examining Complex Responses In Light Of The Teacher's Purpose, Joyce E. Many, Jacqueline K. Gerla, Donna L. Wiseman, Linda Ellis

Faculty Publications

In classroom literature discussions, teachers orchestrate situations in which readers and texts come together. Approaches teachers use may differ in terms of the stance or purpose for reading encouraged. Rosenblatt (1978, 1985) describes two stances readers can take while reading literary works. An efferent stance indicates a reader's attention is focused on information to be retained after reading and can result in a study of the text. An aesthetic stance, on the other hand, occurs when the reader's attention is on the livedthrough experience of the story and the experiences, thoughts, feelings, images, and associations which are evoked. Rosenblatt (1978, …

A Staggered-Diamond Design For Automated/Manual-Hov Highway-To-Highway Interchanges And Constraints On Ahs Design For Accommodating Automated Highway Change, Jacob Tsao Jan 1995

A Staggered-Diamond Design For Automated/Manual-Hov Highway-To-Highway Interchanges And Constraints On Ahs Design For Accommodating Automated Highway Change, Jacob Tsao

Faculty Publications

This paper consists of two components. The First component addresses a key AHS infrastructure support issue—providing eight extra connector ramps, in addition to the eight existing highway-to-highway connector ramps for the conventional manual traffic, at a highway-to-highway interchange for accommodating continuous automated driving from one highway to the crossing highway. The proposed staggered-diamond design requires only four, instead of eight, separate structures and hence greatly increases the feasibility of AHS infrastructure support. However, the reduced infrastructure complexity at such interchanges could still constrain considerably the design, operation and evolution of AHS. This is the focus of the second component. The …

Stage Definition For Ahs Deployment And An Ahs Evolutionary Scenario, Jacob Tsao Jan 1995

Stage Definition For Ahs Deployment And An Ahs Evolutionary Scenario, Jacob Tsao

Faculty Publications

Pros and cons of various mature Automated Highway Systems (AHS) have been a subject of intense study. However, such discussions are nothing but intellectual exercises unless the issue of how to evolve, in a planned and managed fashion, the current highway systems towards these mature AHS is also addressed. Since full functionality of a mature AHS cannot be realized suddenly, discrete functional steps must be identified and optimized. This paper defines an evolutionary stage towards a mature AHS as any discernible functional increment whose realization may encounter considerable difficulties requiring a significant amount of conscious effort to overcome. A good …

Multilevel Block Coded 8-Psk Modulations Using Unequal Error Protection Codes For The Rayleigh Fading Channel, Robert H. Morelos-Zaragoza, Tadeo Kamasi, Shu Lin Jan 1995

Multilevel Block Coded 8-Psk Modulations Using Unequal Error Protection Codes For The Rayleigh Fading Channel, Robert H. Morelos-Zaragoza, Tadeo Kamasi, Shu Lin

Faculty Publications

This paper introduces new block coded 8-PSK modulations with unequal error protection (UEP) capabilities for Rayleigh fading channels. The design of efficient block coded modulations (BCM) over 8-PSK signal sets, for the specific purpose of UEP, over Rayleigh fading channels is considered. UEP is desirable in communications systems where part of the source information is more important, or error sensitive, such as the transmission of coded speech and data broadcasting. The proposed block modulation codes are based on the multilevel construction of Imai and Hirakawa (1977). It is shown that the use of binary linear UEP (LUEP) codes as component …

Consensus Of The Governed: The Legitimacy Of Constitutional Change, Raymond Shih Ray Ku Jan 1995

Consensus Of The Governed: The Legitimacy Of Constitutional Change, Raymond Shih Ray Ku

Faculty Publications

This Article argues that, contrary to current practices, constitutional change is legitimate only when it commands the unanimous support of the people, or, because unanimous support is practically impossible, when it is accomplished through procedural devices (i.e., representation, ratification, and supermajority support) that safeguard minority interests in an effort to determine the public good and approximate the will of the people as a whole. Constitutional change is illegitimate when it represents only the will of a portion of the people. This Article attempts to answer the question of what makes a constitution or a constitutional amendment legitimate, and provides specific …

Deference, Defiance, And Useful Arts, Craig Allen Nard Jan 1995

Deference, Defiance, And Useful Arts, Craig Allen Nard

Faculty Publications

My objective in this Article is to demonstrate that the PTO's patentability determinations are questions of policy and, therefore, the Federal Circuit's standards of review, as applied to these determinations, are unsound. With respect to the Commissioner's statutory interpretations, I intend to demonstrate that the court's “traditional factors of statutory construction,” which are used in such a way as to avoid deferring to the PTO, result in irrational decisions, or at the very least, an alternative theory of interpretation no more convincing than that put forth by the PTO. My principle assertion, grounded in both doctrine and policy, is that …

Qpsk Block-Modulation Codes For Unequal Error Protection, Robert H. Morelos-Zaragoza, Shu Lin Jan 1995

Qpsk Block-Modulation Codes For Unequal Error Protection, Robert H. Morelos-Zaragoza, Shu Lin

Faculty Publications

Unequal error protection (UEP) codes find applications in broadcast channels, as well as in other digital communication systems, where messages have different degrees of importance. Binary linear UEP (LUEP) codes combined with a Gray mapped QPSK signal set are used to obtain new efficient QPSK block-modulation codes for unequal error protection. Several examples of QPSK modulation codes that have the same minimum squared Euclidean distance as the best QPSK modulation codes, of the same rate and length, are given. In the new constructions of QPSK block-modulation codes, even-length binary LUEP codes are used. Good even-length binary LUEP codes are obtained …

Wilderness Planning: A Case Study In Dispute Resolution, Michael Legg, Marlene Rebori Tull Jan 1995

Wilderness Planning: A Case Study In Dispute Resolution, Michael Legg, Marlene Rebori Tull

Faculty Publications

Local landowners and environmental groups have historically disputed with the USDA National Forest Service in Texas over wilderness management issues such as wild and prescribed fire and management of the southern pine beetle (Dendroctonusfrontalis). To help diffuse polarization and open lines of communication between agency personnel and the general public, the theory of transactive planning was applied with the LAC process on two wilderness areas. Data collection consisted of: 1) participant observation; 2) issue-evaluation surveys; 3) process-evaluation surveys; and 4) exit interviews. Results indicate the planning process aids in dispute resolution by reducing antagonistic relationships and fostering public consensus in …

Comments On A Revised Filing System, R. Wilson Freyermuth Jan 1995

Comments On A Revised Filing System, R. Wilson Freyermuth

Faculty Publications

Professor Edward Adams's article, both in terms of its basic structure and the myriad of options it offers, neatly highlights the basic dilemma facing the Drafting Committee as it addresses the future Article 9 filing system. As he correctly notes, the filing system's shortcomings are largely due to its continued dependence on paper records, despite the increasing sophistication and availability of computerized information technology for both filing and searching. Should the Drafting Committee maintain the basics of the current system (a public, paper-based filing system) and merely attempt to identify and correct the existing shortcomings in that system, with some …

A Consistent Boltzmann Algorithm, Alejandro Garcia, F. Alexander, B. Alder Jan 1995

A Consistent Boltzmann Algorithm, Alejandro Garcia, F. Alexander, B. Alder

Faculty Publications

The direct simulation Monte Carlo method for the Boltzmann equation is modified by an additional displacement in the advection process and an enhanced collision rate in order to obtain the exact hard sphere equation of state at all densities. This leads to consistent thermodynamic and transport properties in the low density (Boltzmann) regime. At higher densities transport properties are comparable to the predictions of the Enskog model. The algorithm is faster than molecular dynamics at low and moderate densities and readily run on a parallel architecture

Abortion Counseling As Vice Activity: The Free Speech Implications Of Rust V. Sullivan And Planned Parenthood V. Casey, Christina E. Wells Jan 1995

Abortion Counseling As Vice Activity: The Free Speech Implications Of Rust V. Sullivan And Planned Parenthood V. Casey, Christina E. Wells

Faculty Publications

Part I of this article discusses the Court's opinions in Rust and Casey. It first demonstrates that the driving force in both decisions was the Court's characterization of abortion counseling as an activity rather than as speech. Part I further discusses the speech/conduct distinction in First Amendment jurisprudence and demonstrates that abortion counseling falls on the speech side of that distinction. Parts II and III suggest that the real cause of the conflation of speech and conduct in Rust and Casey was the confluence of (1) the reemergence of reasoning found in a curious commercial speech decision -- Posadas de …
