How Employment-Discrimination Plaintiffs Fare In The Federal Courts Of Appeals, Kevin M. Clermont, Theodore Eisenberg, Stewart J. Schwab Jan 2003

How Employment-Discrimination Plaintiffs Fare In The Federal Courts Of Appeals, Kevin M. Clermont, Theodore Eisenberg, Stewart J. Schwab

Cornell Law Faculty Publications

Employment-discrimination plaintiffs swim against the tide. Compared to the typical plaintiff, they win a lower proportion of cases during pretrial and after trial. Then, many of their successful cases are appealed. On appeal, they have a harder time in upholding their successes, as well in reversing adverse outcome.

This tough story does not describe some tiny corner of the litigation world. Employment-discrimination cases constitute an increasing fraction of the federal civil docket, now reigning as the largest single category of cases at nearly 10 percent.

In this article, we use official government data to describe the appellate phase of this …

Discrete Velocity Fields With Explicitly Computable Lagrangian Law, Curtis D. Bennett, Craig L. Zirbel Jan 2003

Discrete Velocity Fields With Explicitly Computable Lagrangian Law, Curtis D. Bennett, Craig L. Zirbel

Mathematics, Statistics and Data Science Faculty Works

We introduce a class of random velocity fields on the periodic lattice and in discrete time having a certain hidden Markov structure. The generalized Lagrangian velocity (the velocity field as viewed from the location of a single moving particle) has similar hidden Markov structure, and its law is found explicitly. Its rate of convergence to equilibrium is studied in small numerical examples and in rigorous results giving absolute and relative bounds on the size of the second–largest eigenvalue modulus. The effect of molecular diffusion on the rate of convergence is also investigated; in some cases it slows convergence to equilibrium. …

Stably Folded De Novo Proteins From A Designed Combinatorial Library, David Moffet Jan 2003

Stably Folded De Novo Proteins From A Designed Combinatorial Library, David Moffet

Chemistry and Biochemistry Faculty Works

Binary patterning of polar and nonpolar amino acids has been used as the key design feature for constructing large combinatorial libraries of de novo proteins. Each position in a binary patterned sequence is designed explicitly to be either polar or nonpolar; however, the precise identities of these amino acids are varied extensively. The combinatorial underpinnings of the "binary code" strategy preclude explicit design of particular side chains at specified positions. Therefore, packing interactions cannot be specified a priori. To assess whether the binary code strategy can nonetheless produce well-folded de novo proteins, we constructed a second-generation library based upon a …


Storm Effects On Regional Beach Water Quality Along The Southern California Shoreline, Rachel T. Nobel, Stephen B. Weisberg, Molly K. Leecaster, Charles D. Mcgee, John Dorsey, Patricia Vainik, Victoria Orozco-Borbón Jan 2003

Storm Effects On Regional Beach Water Quality Along The Southern California Shoreline, Rachel T. Nobel, Stephen B. Weisberg, Molly K. Leecaster, Charles D. Mcgee, John Dorsey, Patricia Vainik, Victoria Orozco-Borbón

Civil and Environmental Engineering Faculty Works

Two regional studies conducted during dry weather demonstrated that the Southern California Bight (SCB) shoreline has good water quality, except near areas that drain land-based runoff. Here, we repeat those regional studies 36 h after a rainstorm to assess the influence of runoff under high flow conditions. Two hundred and fifty-four shoreline sites between Santa Barbara, California and Ensenada, Mexico were sampled using a stratified-random sampling design with four strata: sandy beaches, rocky shoreline, shoreline adjacent to urban runoff outlets that flow intermittently, and shoreline adjacent to outlets that flow year-round. Each site was sampled for total coliforms, fecal coliforms …

A Geometric Interpretation Of Milnor's Triple Invariants, Blake Mellor, Paul Melvin Jan 2003

A Geometric Interpretation Of Milnor's Triple Invariants, Blake Mellor, Paul Melvin

Mathematics, Statistics and Data Science Faculty Works

Milnor's triple linking numbers of a link in the 3-sphere are interpreted geometrically in terms of the pattern of intersections of the Seifert surfaces of the components of the link. This generalizes the well known formula as an algebraic count of triple points when the pairwise linking numbers vanish.

Chemical Vapor Deposited Diamond Films For Self-Referencing Fiber Optic Raman Probes, Sacharia Albin, Jianli Zheng, Bing Xiao, John B. Cooper, Robert B. Jeffers, Sonia Antony

Chemistry & Biochemistry Faculty Publications

Diamond thin films grown by the microwave plasma enhances chemical vapor deposition (CVD) process have been investigated as an internal reference in fiber optic remote Raman sensing. The growth parameters have been optimized for diamond thin films on quarts substrates using a gas mixture of methane, carbon dioxide, and hydrogen. The resulting films exhibit essentially no Raman spectral background while exhibiting a strong Raman peak at 1332 cm-¹. The films are used as an internal reference in the quantitative measurement of chemical concentration using remote fiber optic Raman sensing. Internal referencing is accomplished by normalizing all spectral intensities …


Sonogashira Coupling Routes To Ortho-Alkynl-And- Fused-Ring Sydnones, Andrew John Weisner Jan 2003

Sonogashira Coupling Routes To Ortho-Alkynl-And- Fused-Ring Sydnones, Andrew John Weisner

Browse all Theses and Dissertations

In the present work, suitably functionalized arylsydnones were used to synthesize a variety of ortho-alkynyl sydnones both as potential precursors to novel sydnoquinolines and to provide non-linear optical (NLO) species of interest to Wright-Patterson Air Force Base (WPAFB). The versatile intermediate, 3-(2-(trimethylsilylethynyl)phenyl)sydnone, was prepared in good yield by the coupling of 3-(2-iodophenyl)sydnone with trimethylsilyl acetylene under Sonogashira conditions. From this intermediate, several ortho-alkynyl sydnones were prepared via a one-pot desilylation with tetrabutylammonium fluoride and Sonogashira coupling with para-substituted aryl iodides. In addition, a three-reaction-in-one-pot procedure was developed to access some of these species directly from 3-(2- iodophenyl)-sydnone. Subsequent reaction of …


Identification Of Gypsy Moth Defoliation In Ohio Using Landsat Data, Angela Lorraine Hurley Jan 2003

Identification Of Gypsy Moth Defoliation In Ohio Using Landsat Data, Angela Lorraine Hurley

Browse all Theses and Dissertations

The gypsy moth is one of the most devastating forest pests in North America. In late spring, gypsy moth larvae hatch from eggs laid the previous summer. During the next forty days, tens of thousands of these caterpillars eat up to one square foot of foliage each. The gypsy moth has established populations in several states, and dangerously fast-growing populations in several others. The state of Ohio is a critical area in the suppression of the gypsy moth because the front of gypsy moth advance passes through the state. Besides diminishing the aesthetic value of Ohio’s forests, gypsy moths also …

Public Trust Doctrine And Public Access In New Jersey, Urban Harbors Institute, University Of Massachusetts Boston Jan 2003

Public Trust Doctrine And Public Access In New Jersey, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

A discussion paper prepared as part of a series of focus groups on the topic of the Public Trust Doctrine and Public Access in New Jersey.

Public access is specifically identified as one of the key priorities of the Coastal Zone Management Act (CZMA) of 1972. More importantly, the Act enables states to develop their own coastal zone management programs and to receive federal funding with which to implement them. There are a number of criteria that such plans must include before they can receive federal approval.


Decoherence In Two Coupled Qubits, Kristian Rabenstein, Dmitri V. Averin Jan 2003

Decoherence In Two Coupled Qubits, Kristian Rabenstein, Dmitri V. Averin

Turkish Journal of Physics

We have developed quantitative description of quantum coherent oscillations in the system of two coupled qubits in the presence of weak decoherence that in general can be correlated between the two qubits. It is shown that in the experimentally realized scheme of excitation of the oscillations, their waveform is not very sensitive to the magnitude of decoherence correlations. Modification of this scheme into potentially useful probe of the degree of decoherence correlations at the two qubits is suggested.

Persistence In Mathematics By Underrepresented Students: Experiences Of A Math Excel Program, C. M. Hake, M. L. Crow, T. Dick

Journal of Mathematics and Science: Collaborative Explorations

Success in mathematics by underrepresented and nontraditional college students is measured not only by academic performance (grades), but also by the continued participation and persistence of these students in mathematics coursework. The Math Excel program at Oregon State University attempts to build "learning communities" with a sharp academic focus in support of students concurrently taking introductory level mathematics courses. The Math Excel program is based heavily on Uri Treisman's Emerging Scholars Workshop model of collaborative problem solving. In this article, we examine the experience of minority students in the Educational Opportunities Program participating in the Math Excel program. While the …

Sibling Recurrence Risk Ratio Analysis Of The Metabolic Syndrome And Its Components Over Time., Wei J. Chen, Pi Hua Liu, Yen Yi Ho, Kuo Liong Chien, Min Tzu Lo, Wei Liang Shih, Yu Chun Yen, Wen Chung Lee

Faculty Publications

The purpose of this study was to estimate both cross-sectional sibling recurrence risk ratio (lambdas) and lifetime lambdas for the metabolic syndrome and its individual components over time among sibships in the prospectively followed-up cohorts provided by the Genetic Analysis Workshop 13. Five measures included in the operational criteria of the metabolic syndrome by the Adult Treatment Panel III were examined. A method for estimating sibling recurrence risk with correction for complete ascertainment was used to estimate the numerator, and the prevalence in the whole cohort was used as the denominator of lambdas. Considerable variability in the lambdas was found …


Agent Based Intrusion Detection And Response System For Wireless Lans, Mohan K Chirumamilla, Byrav Ramamurthy Jan 2003

Agent Based Intrusion Detection And Response System For Wireless Lans, Mohan K Chirumamilla, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Wireless LAN technology, despite the numerous advantages it has over competing technologies, has not seen widespread deployment. A primary reason for markets not adopting this technology is its failure to provide adequate security. Data that is sent over wireless links can be compromised with utmost ease. In this project, we propose a distributed agent based intrusion detection and response system for wireless LANs that can detect unauthorized wireless elements like access points, wireless clients that are in promiscuous mode etc. The system reacts to intrusions by either notifying the concerned personnel, in case of rogue access points and promiscuous nodes, …

Patterns And Trends Of Soil Climate Regimes And Drought Events In The Northern Great Plains, William J. Waltman, Stephen M. Goddard, S. E. Reichenbach, Mark Svoboda, Michael Hayes, J. S. Peake Jan 2003

Patterns And Trends Of Soil Climate Regimes And Drought Events In The Northern Great Plains, William J. Waltman, Stephen M. Goddard, S. E. Reichenbach, Mark Svoboda, Michael Hayes, J. S. Peake

School of Computing: Conference and Workshop Papers

Drought is the dominant process of crop loss nationally and within Nebraska. Nearly twothirds of the 18.6 million harvested acres are covered by crop insurance (USDA/RMA, 2003; USDA/NASS, 2003). For the most part, Nebraska’s crop losses range from $50 to 75 million in non-drought years, but the losses approach nearly $200 million in drought years, such as 2000. The past growing season (2002) crop losses are projected to greatly exceed $375 million in Nebraska and more than $4 billion nationally (USDA/RMA, 2003). The analysis and understanding of drought processes in the Great Plains is an important component to developing drought …


Estimation Of Hydraulic Conductivity From Borehole Flowmeter Tests Considering Head Losses, Vitaly A. Zlotnik, Brian R. Zurbuchen Jan 2003

Estimation Of Hydraulic Conductivity From Borehole Flowmeter Tests Considering Head Losses, Vitaly A. Zlotnik, Brian R. Zurbuchen

Department of Earth and Atmospheric Sciences: Faculty Publications

Recent numerical studies have demonstrated that the conventional interpretation of the borehole flowmeter test (BFT) may lead to considerable errors in estimates of the horizontal hydraulic conductivity (Kr) due to neglect of head loss across the electromagnetic borehole flowmeter (EBF). Even in uniform aquifers, the conventional interpretation underestimates Kr at the base and overestimates Kr at the top of the aquifer. In this paper, we derive exact analytical solutions for hydraulic head and streamlines induced by the BFT in a confined homogeneous aquifer. The solutions explicitly consider head loss across the EBF. The derived analytical solutions …
