Goethe's Die Leiden Des Jungen Werthers: An Epistolary Novel, Or A Stage Drama In Disguise?, Ilona Klein

Faculty Publications

Photography of the late 1920s generated repercussions in other fields of the arts. It sparked an interdisciplinary interest in critics who balked at viewing the frozen images as merely one moment's reality, and who wanted, instead, to recompose and integrate underlying cultural, literary, or political discourse within the photographic frame. This fertile interdisciplinary backing guaranteed an in-depth interpretative dissection of artistic expression which had not been previously possible. The small photograph, a still visual image, became connected to the larger visual images of stage sets-these, a series of visual, immobile backgrounds which framed the caracters acting within.

Employment Separation And Health Insurance Coverage, Jonathan Gruber, Brigitte C. Madrian

Faculty Publications

We study the interrelationship between employment separation and insurance coverage. We first document that employment separation is associated with large reductions in insurance coverage, even conditioning on underlying tastes for insurance.We then show that reducing the cost of insurance through state laws mandating continued access to employerprovided health insurance for the non-employed increases the likelihood of having insurance after separating from a job by 6.7%. These mandates also increase the number of individuals who separate and the total amount of time spent jobless. Finally, at least some of this increased non-employment appears to be spent in productive job search as …

The Delisting Bias In Crsp Data, Tyler Shumway

Faculty Publications

I document a delisting bias in the stock return data base maintained by the Center for Research in Security Prices (CRSP). I find that delists for bankruptcy and other negative reasons are generally surprises and that correct delisting returns are not available for most of the stocks that have been delisted for negative reasons since 1962. Using over-the-counter price data, I show that the omitted delisting returns are large. Implications of the bias are discussed.

The Influence Of Decision Aids On User Behavior: Implications For Knowledge Acquisition And Inappropriate Reliance, Steven M. Glover, Douglas F. Prawitt, Brian C. Spilker

Faculty Publications

Structured decision aids are widely used in many organizational settings, and their influence on judgment consistency and accuracy have received considerable attention in the literature. While two benefits commonly associated with decision aid use are improved judgment and enhanced expertise development, relatively little attention has been directed toward the potential influence of decision aids on decision maker behavior. In particular, we argue that the use of structured aids may influence relatively inexperienced decision makers to approach aided tasks mechanistically, without becoming actively involved in the task or judgment. Such passive decision behavior may, in some situations, threaten gains in performance …

Faster Ray Tracing Using Adaptive Grids, Thomas W. Sederberg, Krysztof S. Klimaszewski

Faculty Publications

A new hybrid approach is presented which outperforms the regular grid technique in scenes with highly irregular object distributions by a factor of hundreds, and combined with an area interpolator, by a factor of thousands. Much has been said about scene independence of different acceleration techniques and the alleged superiority of one approach over another. Several theoretical and practical studies conducted in the past have led to the same conclusion: a space partitioning method that allows the fastest rendering of one scene often fails with another. Specialization may be the answer. This has always been pursued, consciously or not, in …

Damped Diocotron Quasi-Modes Of Non-Neutral Plasmas And Inviscid Fluids, S. Neil Rasband, Ross L. Spencer

Faculty Publications

Computations of damped diocotron oscillations (quasi-modes) are described for non-neutral plasmas and inviscid fluids. The numerical method implements a suggestion made by Briggs, Daugherty, and Levy some 25 years ago [Phys. Fluids 13, 421 (1970)] to push the branch line that forms the continuum into the complex w-plane by solving the mode equation in the complex r-plane. For the special case of power-law density profiles the calculation finds the same quasi-mode frequencies found recently by Corngold [Phys. Plasmas 2, 620 (1995)]. It is found that the feature of the continuum eigenfunctions which indicates the presence of a nearby quasi-mode is …

Pseudospin Transformation Of Physical Operators, A. L. Blokhin, C. Bahri, J. P. Draayer

Faculty Publications

A procedure for applications of the pseudospin transformation within the framework of nuclear oscillator shell model is developed. It is valid for operators expressed in terms of single-particle variables and is based on permutation rules for special rotational invariants. The procedure is applied to a number of physical operators including several rotational scalars, the spin and orbital momenta, and the quadrupole moment. An algorithm for generating an approximation to the pseudospin transformation, which gives a simple and accurate expression for dominant parts of required transforms, is also given. The algebras associated with pseudospin transformations are discussed. © 1996 IOP Publishing …

Early Agriculture In The Maya Lowlands, Mary D. Pohl, Kevin O. Pope, John G. Jones, John S. Jacob, Dolores R. Piperno, Susan D. Defrance, David L. Lentz, John A. Gifford, Marie E. Danforth, J. Kathryn Josserand

Faculty Publications

Wetland research in northern Belize provides the earliest evidence for development of agriculture in the Maya Lowlands. Pollen data confirm the introduction of maize and manioc before 3000 B.C. Dramatic deforestation, beginning ca. 2500 B.C. and intensifying in wetland environments ca. 1500-1300 B.C., marks an expansion of agriculture, which occurred in the context of a mixed foraging economy. By 1000 B.C. a rise in groundwater levels led farmers to construct drainage ditches coeval with the emergence of Maya complex society ca. 1000-400 B.C. Field manipulations often involved minor modifications of natural hummocks. Canal systems are not as extensive in northern …

Detection For A Statistically-Known, Time-Varying Dispersive Channel, David W. Matolak, S. G. Wilson

Faculty Publications

Detection for the statistically known channel (SKC) is aimed at obtaining good performance in situations where our statistical knowledge of a time-varying channel is good, and where other equalization/detection schemes are either too complex to implement, or their performance is limited due to the rapidity of channel fading, or where we are simply unable to perform channel estimation. By using a statistical characterization of the channel, we develop a new detector that performs maximum-likelihood sequence estimation (MLSE) (given the channel model) on blocks of N symbols. Both symbol-spaced and fractionally spaced samples are used, to obtain two different detectors, that …

Ground‐Based Measurements Of Nox And Total Reactive Oxidized Nitrogen (Noy) At Sable Island, Nova Scotia, During The Nare 1993 Summer Intensive, T. Wang, M. A. Carroll, G. M. Albercook, K. R. Owens, Katharine A. Duderstadt, A. N. Markevitch, D. D. Parrish, J. S. Holloway, F. C. Fehsenfeld, G. Forbes, J. Ogren

Faculty Publications

Measurements of NO, NO2, and total reactive oxidized nitrogen (NOy) were added to ongoing measurements of aerosols, CO, and O3 at Sable Island (43°55′N, 60°01′W), Nova Scotia, during the North Atlantic Regional Experiment (NARE) 1993 summer intensive. Ambient levels of NOx and NOy were found to be highly variable, and elevated levels can be attributed to the transport of polluted continental air or presumably to relatively fresh emissions from sources upwind (e.g., ship traffic). The median values for NOx and NOy are 98 and 266 parts per trillion by volume (pptv), respectively. A multiday pollution episode occurred during which elevated …

Activation Of Δ-Globin Gene Expression By Erythroid Krupple-Like Factor: A Potential Approach For Gene Therapy Of Sickle Cell Disease, David Donze, Paxson H. Jeancake, Tim M. Townes

Faculty Publications

Hemoglobin A2 (HbA2; α2δ2) is a powerful inhibitor of HbS (α2β2/(S) polymerization. However, HbA2 levels are normally low in sickle cell patients. We show that a major reason for low δ-globin gene expression is the defective CACCC box at -90 in the δ-globin promoter. When the CACCC box defect in δ is corrected, expression of an HS2 δ/Luciferase reporter is equivalent to HS2 β/Luciferase. Erythroid Krupple-like factor (EKLF), which binds to the CACCC box of the β-globin gene and activates high-level expression, does not bind to the normal δ-globin promoter. Our goal is to design a modified EKLF that binds …

Nonequilibrium Critical Dynamics Of A Three Species Monomer-Monomer Model, Kevin E. Bassler, Dana A. Browne

Faculty Publications

We study a three species monomer-monomer catalytic surface reaction model with a reactive steady state bordered by three equivalent unreactive phases where the surface is saturated with one species. The transition from the reactive to a saturated phase shows directed percolation critical behavior. Each pair of these reactive-saturated phase boundaries joins at a bicritical point where the universal behavior is in the even branching annihilating random walk class. We find the crossover exponent from bicritical to critical behavior and a new exponent associated with the bicritical interface dynamics. © 1996 The American Physical Society.

Large-Area Sub-Millimeter Resolution Cdznte Strip Detector For Astronomy, J. R. Macri, B. A. Apotovsky, J. F. Butler, M. L. Cherry, B. K. Dann, F. P. Doty, T. G. Guzik, M. L. Mcconnell, J. M. Ryan

Faculty Publications

We report performance measurements of a sub-millimeter resolution CdZnTe strip detector developed as a prototype for astronomical instruments. The prototype is a 1.4 mm thick, 64 × 64 stripe CdZnTe array with 0.375 mm pitch in both dimensions. Pulse height spectra in orthogonal stripe coincidence mode were recorded at several energies. The room-temperature energy resolution is (FWHM) for 122 keV photons with a peak-to-valley ratio >5:1. We also demonstrate spatial resolution capabilities finer than the stripe pitch.

A Fertility Channel Model For Post-Correction Of Continuous Speech Recognition, Eric K. Ringger, James F. Allen

Faculty Publications

We have implemented a post-processor called SPEECHPP to correct word-level errors committed by an arbitrary speech recognizer. Applying a noisy-channel model, SPEECHPP uses a Viterbi beam-search that employs language and channel models. Previous work demonstrated that a simple word-for-word channel model was sufficient to yield substantial incieases in word accuracy. This paper demonstrates that some improvements in word accuracy result from augmenting the channel model with an account of word fertility in the channel. This work further demonstrates that a modern continuous speech recognizer can be used in "black-box" fashion for robustly recognizing speech for which the recognizer was not …

Jet photoproduction, where the two highest transverse energy (ETjet) jets have ETjet above 6 GeV and a jet-jet invariant mass above 23 GeV, has been studied with the ZEUS detector at the HERA ep collider. Resolved and direct photoproduction samples have been separated. The cross section as a function of the angle between the jet-jet axis and the beam direction in the dijet rest frame has been measured for the two samples. The measured angular distributions differ markedly from each other. They agree with the predictions of QCD calculations, where the different angular distributions reflect the different spins of the …

In deep inelastic neutral current scattering of positrons and protons at the center of mass energy of 300 GeV, we observe, with the ZEUS detector, events with a high energy neutron produced at very small scattering angles with respect to the proton direction. The events constitute a fixed fraction of the deep inelastic, neutral current event sample independent of Bjorken x and Q2 in the range 3 · 10-4 < xBJ < 6 · 10-3 and 10 < Q2 < 100 GeV2.

Theory And Operation Of Continuous Flow Systems For The Study Of Benthic-Pelagic Coupling, Tina Miller-Way, Robert R. Twilley

Faculty Publications

Continuous flow systems have not been widely used in the study of benthic-pelagic coupling in marine systems. This paper discusses the theoretical and practical use of continuous flow sysrems for the study of benthic exchange processes and presents the results of experiments which compared continuous flow (open) and closed (batch) systems and investigated the sensitivity of exchange rates to residence times in a continuous flow system. Continuous flow systems minimize the problem of environmental dependency of benthic-pelagic exchange rates by maintaining initial experimental conditions throughout an incubation. However, the selection of a supply rate (i.e. residence time) is critical in …
