Marital Status Discrimination: A Proposal For Title Vii Protection, Nicole Buonocore Porter

Faculty Publications

Marital status is not one of the protected categories of Title VII of the Civil Rights Act of 1964, the federal antidiscrimination statute that governs discrimination in employment. This Article will argue that to avoid the types of inequities caused by marital status discrimination, it is necessary for Title VII to protect employees against marital status discrimination.

The more common claims of marital status discrimination are claims that an employer's no-spouse rule or antinepotism policy violates the state antidiscrimination statute. [These policies have two significant problems.] First of all, many courts fail to look at the widely disparate consequences of …

Unmanned Research Vehicle (Urv): Development, Implementation, & Flight Test Of A Mimo Digital Flight Control System Designed Using Quantitative Feedback Theory, Constantine H. Houpis, Steven J. Rasmussen

Faculty Publications

The Quantitative Feedback Theory (QFT) design technique, which has the ability to bridge the gap between theory and the real-world control design problem, is utilized in the design of a MIMO digital flight control system for an unmanned research vehicle (URV) that is presented in this paper. The design illustrates how the real-world knowledge of the plant to be controlled and the desired performance specifications can be utilized in trying to achieve a successful robust design for a nonlinear control problem. This paper presents some of the issues involved in developing, implementing, and flight testing a flight control system (FCS) …

Choice Of Small Business Tax Entity, John W. Lee

Faculty Publications

This article summarizes parts of Lee’s forthcoming article “A Populist Political Perspective of the Business Tax Entities Universe: Hey the Stars Might Lie But the Numbers Never Do,” 78 Texas L. Rev. 885 (2000). Conventional wisdom, says Lee, holds that the LLC, due to its limited liability and hassle-free single level of taxation, will supplant C and S corporations as the choice of entity for new businesses. In fact, in most jurisdictions corporate formations outnumber LLC formations 2:1 or more, and IRS Statistics of Income (SOI) projects that the S corporation will be the fastest growing tax entity for 2000 …

Glycoprotein B Of Human Herpesvirus 8 Is A Component Of The Virion In A Cleaved Form Composed Of Amino- And Carboxyl-Terminal Fragments, Abolghasem Baghian, Micah Luftig, Jodi B. Black, Yuan Xiang Meng, Chou Pong Pau, Thomas Voss, Philip E. Pellett, Konstantin G. Kousoulas

Faculty Publications

Human herpesvirus 8 (HHV-8) or Kaposi's sarcoma-associated herpesvirus (KSHV) is the only known human member of the Rhadinovirus genus of the gammaherpesvirus subfamily. Antibodies against peptides representing portions of the amino-and carboxyl-termini of HHV-8 gB were produced and used to detect gB expression in Vero cells transfected with the gB gene, in the HHV- 8-harboring cell line, BCBL-1, and in purified virions. Expression of gB was detected in approximately 3% of uninduced BCBL-1 cells, while up to 30% of the cells expressed gB after 12-O-tetradecanoylphorbol-13-acetate (TPA) induction of virus replication. Indirect immunofluorescence assays and confocal microscopy showed that gB was …

Strong Species Dependence Of High Order Photoelectron Production In Alkali Metal Atoms, M. B. Gaarde, K. J. Schafer, K. C. Kulander, B. Sheehy, Dalwoo Kim, L. F. Dimauro

Faculty Publications

We present a theoretical and experimental study of the production of very high order photoelectrons from alkali metal atoms interacting with intense, midinfrared radiation. The strength of this process shows an unexpectedly strong species dependence. We find that this dependence can be explained via the difference in the cross section for electron-ion scattering from the different atoms. This allows us to directly relate the high energy portion of the photoelectron spectrum to specific features of the electron-ion potential. © 2000 The American Physical Society.

Can Light Echoes Account For The Slow Decay Of Type Iin Supernovae?, Bruce Roscherr, Bradley E. Schaefer

Faculty Publications

The spectra of Type Un supernovae indicate the presence of a preexisting slow, dense circumstellar wind (CSW). If the CSW extends sufficiently far from the progenitor star, then dust formation should occur in the wind. The light from the supernova explosion will scatter off this dust and produce a light echo. Continuum emission seen after the peak will have contributions from both this echo as well as from the shock of the ejecta colliding with the CSW, with a fundamental question of which source dominates the continuum. We calculate the brightness of the light echo as a function of time …

Close Limit Of Grazing Black Hole Collisions: Non-Spinning Holes, Gaurav Khanna, Reinaldo Gleiser, Richard Price, Jorge Pullin

Faculty Publications

Using approximate techniques we study the final moments of the collision of two (individually non-spinnning) black holes which inspiral into each other. The approximation is based on treating the whole spacetime as a single distorted black hole. We obtain estimates for the radiated energy, angular momentum and waveforms for the gravitational waves produced in such a collision. The results can be of interest for analysing the data that will be forthcoming from gravitational wave interferometric detectors, like the LIGO, GEO, LISA, VIRGO and TAMA projects.

Some Generalizations Of The Kadomtsev-Petviashvili Equations, Michael M. Tom

Faculty Publications

The question of globalization of solutions of the Cauchy problem for some generalizations of Kadomtsev-Petviashvili equations of the form (ut + u^pux -D^αxux)x + εuyy = 0, where Dx = (- ∂²x)^1/2 and ε = ± 1 is examined. It is shown that for ε = -1 and α ≥ 2, a global estimate on solutions can be derived for large initial data provided that p < 4α/4 + α. A consequence of this is that if a is large enough, the local solution in H^s(ℝ²) can be globally continued. © 2000 Academic Press.

Strategic Auditing In A Political Hierarchy: An Informational Model Of The Supreme Court's Certiorari Decisions, Charles M. Cameron, Jeffrey A. Segal, Donald Songer

Faculty Publications

We examine how the Supreme Court uses signals and indices from lower courts to determine which cases to review. In our game theoretic model, a higher court cues from publicly observable case facts, the known preferences of a lower court and its derision. The lower court attempts to enforce its own preferences, exploiting ambiguity in cases' fact patterns. In equilibrium, a conservative higher court declines to review conservative decisions from lower courts regardless of the facts of die case or the relative ideology of the judges. But a conservative higher court probabilistically reviews liberal decisions, with the "audit rate" tied …

Designing Human-Centered Automation: Tradeoffs In Collision Avoidance System Design, Michael A. Goodrich, Erwin R. Boer

Faculty Publications

Technological advances have made plausible the design of automated systems that share responsibility with a human operator. The decision to use automation to assist or replace a human operator in safety-critical tasks must account for not only the technological capabilities of the sensor and control subsystems, but also the autonomy, capabilities, and preferences of the human operator. By their nature, such human-centered automation problems have multiple attributes: an attribute reflecting human goals and capabilities, and an attribute reflecting automation goals and capabilities. Although good theories exist that describe portions of human behavior generation, in the absence of a general theory …

Managing Temporal Data In A Comprehensive Modeling Environment, Norman L. Jones, E. James Nelson, Colby T. Manwaring

Faculty Publications

Numerous graphical pre- and post-processors have been developed for numerical modeling. Many of these systems support numerical models that can be used for both steady state and transient simulations. Dealing with transient data can be particularly difficult in such an environment due to the differing time scales and units associated with transient field data and boundary conditions. A data model and a set of functions are presented in this paper as a simple, yet powerful strategy for managing temporal data in a comprehensive modeling environment. The strategy makes it possible to seamlessly integrate multiple types of transient data and convert …

The forward-jet cross section in deep inelastic e + p scattering has been measured using the ZEUS detector at HERA with an integrated luminosity of 6.36 pb -1 . The jet cross section is presented as a function of jet transverse energy squared, E(T,jet)/ 2 , and Q 2 in the kinematic ranges 10 -2 < E(T,jet)/ 2 /Q 2 < 10 2 and 2.5 · 10 -4 < x < 8.0 · 10 -2 . Since the perturbative QCD predictions for this cross section are sensitive to the treatment of the log(E(T,jet)/ 2 /Q2) terms, this measurement provides an important test. The measured cross section is compared to the predictions of a next-to-leading order pQCD calculation as well as to various leading-order Monte Carlo models. Whereas the predictions of all models agree with the measured cross section in the region of small E(T,jet/ 2 /Q 2 only one model, which includes a resolved photon component, describes the data over the whole kinematic range.

Faculty Publications

The dissociation of PH3 from the 18-electron system CpMoX(PH3)3 to afford the corresponding 16-electron CpMoX(PH3)2 fragment has been investigated theoretically by density functional theory for X = H, CH3, F, Cl, Br, I, OH, and PH2. The product is found to prefer a triplet spin state for all X ligands except PH2, the singlet-triplet gap varying between 1.7 kcal/mol for OH to 8.7 kcal/mol for F. The Mo-PH3 bond dissociation energy to the 16-electron ground state varies dramatically across the series, from 4.5 kcal/mol for OH to 23.5 kcal/mol for H, and correlates with experimental observations on trisubstituted phosphine derivatives. …

Superflares On Ordinary Solar-Type Stars, Bradley E. Schaefer, Jeremy R. King, Constantine P. Deliyannis

Faculty Publications

Short-duration flares are well known to occur on cool main-sequence stars as well as on many types of "exotic" stars. Ordinary main-sequence stars are usually pictured as being static on timescales of millions or billions of years. Our Sun has occasional flares involving up to ∼1031 ergs that produce optical brightenings too small in amplitude to be detected in disk-integrated brightness. However, we identify nine cases of superflares involving 1033-1038 ergs on normal solar-type stars. That is, these stars are on or near the main sequence, are of spectral class F8-G8, are single (or in very wide binaries), are not …

Faculty Publications

The electronic structure of spinel-type Cu1-xNixRh2S4 (x=0.0, 0.1, 0.3, 0.5, 1.0) and CuRh2Se4 compounds has been studied by means of x-ray photoelectron (SPS) and fluorescent spectroscopy. Cu L3, Ni L3, S L2,3, and Se M2,3 x-ray emission spectra (XES) were measured near thresholds at Beamline 8.0 of the Lawrence Berkeley Laboratory's Advanced Light Source. XES measurements of the constituent atoms of these compounds, reduced to the same binding energy scale, are found to be in excellent agreement with XPS valence bands. The calculated XES spectra which include dipole matrix elements show that the partial density of states reproduce experimental spectra …

Multilevel Coded Modulation For Unequal Error Protection And Multistage Decoding—Part I: Symmetric Constellations, Robert H. Morelos-Zaragoza, Marc P. C. Fossorier, Shu Lin, Hideki Imai

Faculty Publications

In this paper, theoretical upper bounds and computer simulation results on the error performance of multilevel block coded modulations for unequal error protection (UEP) and multistage decoding are presented. It is shown that nonstandard signal set partitionings and multistage decoding provide excellent UEP capabilities beyond those achievable with conventional coded modulation. The coding scheme is designed in such a way that the most important information bits have a lower error rate than other information bits. The large effective error coefficients, normally associated with standard mapping by set partitioning, are reduced by considering nonstandard partitionings of the underlying signal set. The …

Numerical Aspects Of Discrete And Continuum Hybrid Models In Cell Biology, J. C. Dallon

Faculty Publications

In this paper we introduce a method of modeling which mixes continuum and discrete variables, and explain two models in cell biology that use this method. The first application deals with wound healing, more specifically the collagen alignment in scar tissue formation and the second models early aggregation in the cellular slime mold Dictyostelium discoideum. We solve these models using numerical techniques similar to the particle-in-cell method which requires that the discrete and continuum variables are interpolated one to the other. The implementational and numerical details are discussed in an informal and practical manner with particular attention given to the …

Comparison Of Tovs-Derived Land Surface Variables With Ground Observations, Venkataraman Lakshmi, Joel Susskind
