Faculty Publications

This collected volume on English language teaching (ELT) in India contains 22 articles written by Indian teachers and researchers. The book has been divided into six sections. The first section—“Problematizing ELT in India”—offers a critical, historical perspective along with innovative ideas for making English language learning and teaching meaningful and purposive in modern India. The second section—“Nature of ELT Materials”—demonstrates how the ELT materials used in Indian classrooms are not embedded in local needs and indigenous contexts. The section emphasizes the importance of developing instructional materials that not only make use of the rich linguistic and cultural resources available in …

The Delisting Bias In Crsp Data, Tyler Shumway Jan 1997

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.

Common Ground: Perspectives On Latino-Latina Diversity, Ediberto Román Jan 1997

Common Ground: Perspectives On Latino-Latina Diversity, Ediberto Román

Faculty Publications

In academic circles, when one speaks of scholarship, one speaks of scholarly legal publications. While such writing is obviously important for reform as well as for professional self-preservation,, I would take the term scholarship a step further. As true students of the law, we have a status in society that gives us a forum, and as Latinos/as we have an obligation to use our status to affect our communities. I, therefore, strongly support becoming more active by getting our voices heard beyond traditional modes of legal discourse. There are scores of communication mediums, such as newspapers and non-legal journals whose …

Faster Ray Tracing Using Adaptive Grids, Thomas W. Sederberg, Krysztof S. Klimaszewski Jan 1997

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 …

Radar Backscatter Measurement Accuracy For A Spaceborne Pencil-Beam Wind Scatterometer With Transmit Modulation, David G. Long, Michael W. Spencer Jan 1997

Radar Backscatter Measurement Accuracy For A Spaceborne Pencil-Beam Wind Scatterometer With Transmit Modulation, David G. Long, Michael W. Spencer

Faculty Publications

Scatterometers are remote sensing radars designed to measure near-surface winds over the ocean. The difficulties of accommodating traditional fan-beam scatterometers on spacecraft has lead to the development of a scanning pencil-beam instrument known as SeaWinds. SeaWinds will be part of the Japanese Advanced Earth Observing Satellite II (ADEOS-II) to be launched in 1999. To analyze the performance of the SeaWinds design, a new expression for the measurement accuracy of a pencil-beam system is required. In this paper the authors derive a general expression for the backscatter measurement accuracy for a pencil-beam scatterometer which includes the effects of transmit signal modulation …

Tradeoffs In The Design Of A Spaceborne Scanning Pencil Beam Scatterometer: Application To Seawinds, David G. Long, Chialin T. Wu, Michael W. Spencer Jan 1997

Tradeoffs In The Design Of A Spaceborne Scanning Pencil Beam Scatterometer: Application To Seawinds, David G. Long, Chialin T. Wu, Michael W. Spencer

Faculty Publications

SeaWinds is a spaceborne wind scatterometer to be flown on the second Japanese Advanced Earth Observing Satellite (ADEOS-II) in 1999. An important international element of NASA's Earth Observing System (EOS), SeaWinds is an advanced follow-on to the NASA scatterometer (NSCAT) on the first ADEOS platform. Unlike previous operational spaceborne scatterometer systems. SeaWinds employs a scanning "pencil-beam" antenna rather than a "fan-beam" antenna, making the instrument more compact and yielding greater ocean coverage. The goals of this paper are twofold. First, the overall SeaWinds functional design and backscatter measurement approach are described, and the relative advantages of the pencil-beam technique are …

Release Of Inorganic Material During Coal Devolatilization, Larry L. Baxter, Reginald E. Mitchell, Thomas H. Fletcher Jan 1997

Release Of Inorganic Material During Coal Devolatilization, Larry L. Baxter, Reginald E. Mitchell, Thomas H. Fletcher

Faculty Publications

Experimental results presented in this paper indicate that coal devolatilization products convectively remove a fraction of the nonvolatile components of inorganic material atomically dispersed in the coal matrix. Results from three facilities burning six different coals illustrate this mechanism of ash transformation and release from coal particles. Titanium is chosen to illustrate this type of mass release from coal particles on the basis of its low volatility and mode of occurrence in the coal. During moderate rates of devolatilization (104 K/s heating rate), no significant loss of titanium is noted. At more rapid rates of heating/devolatilization (105 K/s) …

Soot In Coal Combustion Systems, Thomas H. Fletcher, Jinliang Ma, Jim Rigby, Alexander L. Brown, Brent W. Webb Jan 1997

Soot In Coal Combustion Systems, Thomas H. Fletcher, Jinliang Ma, Jim Rigby, Alexander L. Brown, Brent W. Webb

Faculty Publications

Soot is generated from coal when volatile matter, tar in particular, undergoes secondary reactions at high temperatures. A description of soot in coal flames allows better calculations of radiative transfer and temperatures in near-burner regions, which in turn allows more accurate predictions of NOx formation in coal-fired furnaces. Experiments are reviewed that examine the formation, agglomeration and properties of coal-derived soot, including pyrolysis experiments and combustion experiments. This review includes the types of experiments performed, the soot yields obtained, the size of the soot particles and agglomerates, the optical properties of soot, the relationship between coal-derived soot and soot …

Ontologies For Agents, Michael N. Huhns, Munindar P. Singh Jan 1997

Ontologies For Agents, Michael N. Huhns, Munindar P. Singh

Faculty Publications

An ontology is a computational model of some portion of the world. It is often captured in some form of a semantic network-a graph whose nodes are concepts or individual objects and whose arcs represent relationships or associations among the concepts. This network is augmented by properties and attributes, constraints, functions, and rules that govern the behavior of the concepts. Formally, an ontology is an agreement about a shared conceptualization, which includes frameworks for modeling domain knowledge and agreements about the representation of particular domain theories. Definitions associate the names of entities in a universe of discourse (for example, classes, …

Hierarchical Classification As An Aid To Browsing, John R. Rose, Caroline M. Eastman Jan 1997

Hierarchical Classification As An Aid To Browsing, John R. Rose, Caroline M. Eastman

Faculty Publications

An approach to browsing large chemical reaction databases is presented. The method that is described builds on earlier work in which unsupervised hierarchical classification was used to extract generalizations of reaction classes from reaction databases for use in reaction knowledge bases. The method described in this paper involves classification based on both semantic and topological features. It supports the creation of deep hierarchies in which succeeding levels represent increasing degrees of abstraction. The creation of a hierarchy allows the user to quickly locate interesting items or classes of items by performing a tree traversal as opposed to sequentially scanning a …

Improved Heterogeneous Distance Functions, Tony R. Martinez, D. Randall Wilson Jan 1997

Improved Heterogeneous Distance Functions, Tony R. Martinez, D. Randall Wilson

Faculty Publications

Instance-based learning techniques typically handle continuous and linear input values well, but often do not handle nominal input attributes appropriately. The Value Difference Metric (VDM) was designed to find reasonable distance values between nominal attribute values, but it largely ignores continuous attributes, requiring discretization to map continuous values into nominal values. This paper proposes three new heterogeneous distance functions, called the Heterogeneous Value Difference Metric (HVDM), the Interpolated Value Difference Metric (IVDM), and the Windowed Value Difference Metric (WVDM). These new distance functions are designed to handle applications with nominal attributes, continuous attributes, or both. In experiments on 48 applications …

On The Dynamic Behaviour Of A Thermoviscoelastic Body In Frictional Contact With A Rigid Obstacle, Kenneth Kuttler, K. T. Andrews, M. Shillor Jan 1997

On The Dynamic Behaviour Of A Thermoviscoelastic Body In Frictional Contact With A Rigid Obstacle, Kenneth Kuttler, K. T. Andrews, M. Shillor

Faculty Publications

We consider the dynamic behaviour of a thermoviscoelastic body which may come into frictional contact with a rigid obstacle. The frictional contact is modelled by general contact and friction laws which include as special cases the power law normal compliance condition and the corresponding generalization of Coulomb's law of dry friction. The stress-strain constitutive relation is assumed to be of Kelvin-Voigt type and the frictional heat generation on the contact surface is taken into account. In this setting we establish the existence of a solution to a weak version of the energy-elasticity system which consists of a parabolic equation coupled …

Damped Diocotron Quasi-Modes Of Non-Neutral Plasmas And Inviscid Fluids, S. Neil Rasband, Ross L. Spencer Jan 1997

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 …

Cultural Values And Education In Western Samoa: Tensions Between Colonial Roots And Influences And Contemporary Indigenous Needs, Steven J. Hite, E. Vance Randall, Gaugau Va'afuti Tavana Jan 1997

Cultural Values And Education In Western Samoa: Tensions Between Colonial Roots And Influences And Contemporary Indigenous Needs, Steven J. Hite, E. Vance Randall, Gaugau Va'afuti Tavana

Faculty Publications

The expansion of western culture throughout the world unavoidably alters and re-shapes the perspective of the peoples engulfed by the "West." The western "universalist" culture engenders a premium on values such as "democracy, individualism, and a high standard of living based on material productivity" (Von Laue, 1987, p. 267; Philips, 1992, p. 80). The encroachment of the western colonial era in the pacific areas of Samoa, Tonga, and the Cook Islands began around 1722 and continues in many forms to the present.

Some Reflections At Winter Quarters, Richard E. Bennett

Faculty Publications

On this Memorial Day weekend, it is altogether fitting and appropriate that we gather today at this sacred place to remember the lives of our progenitors everywhere. From Gettysburg to Hiroshima, from Arlington to Flanders Field, and from the city cemetery to the family plot, we honor our dead ancestors and friends long since stilled. Whether they died on the battle fields of war or perished in the labor of giving birth, we honor them. Whether on the trail to a new life in Oregon or a new chance in Ukraine, they all were the lifeline to our present bright …

The Influence Of Decision Aids On User Behavior: Implications For Knowledge Acquisition And Inappropriate Reliance, Steven M. Glover, Douglas F. Prawitt, Brian C. Spilker Jan 1997

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 …

Evaluating Forecasts Of Correlation Using Option Pricing, Michael S. Gibson, Brian H. Boyer Jan 1997

Evaluating Forecasts Of Correlation Using Option Pricing, Michael S. Gibson, Brian H. Boyer

Faculty Publications

A forecast of the correlation between two asset prices is required to price or hedge an option whose payoff depends on both asset prices or to measure the risk of a portfolio whose return depends on both asset prices. However, a number of factors make it difficult to evaluate forecasts of correlation. We develop a forecast evaluation methodology based on option pricing, extending a technique that Engle et al (1993) introduced to evaluate volatility forecasts. A forecast of the variance-covariance matrix of joint asset returns is used to generate a trading strategy for a package of simulated options. The most …

Goethe's Die Leiden Des Jungen Werthers: An Epistolary Novel, Or A Stage Drama In Disguise?, Ilona Klein Jan 1997

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.

Primo Levi, Ilona Klein Jan 1997

Primo Levi, Ilona Klein

Faculty Publications

Chemistry and literature, viewed by most people as widely different subjects, come together in the works of Primo Levi, an Italian Jew who was both a professional chemist and a professional writer. Levi said that he wanted to fill the gap between the imaginative world of literature and the analytical world of science. Believing such a gap absurd, he was never daunted by the purported incompatibility between the two fields of knowledge. Levi's literary work is also marked by his experience in Auschwitz's concentration camp, where he was interned from February 1944 to January 1945. Through his characteristically clear and …

The Ability Of Children With Specific Language Impairment To Participate In A Group Decision Task, Lee Robinson, Martin Fujiki, Bonnie Brinton, Valyne J. Watson Jan 1997

The Ability Of Children With Specific Language Impairment To Participate In A Group Decision Task, Lee Robinson, Martin Fujiki, Bonnie Brinton, Valyne J. Watson

Faculty Publications

This study examined the ability of 6 children with specific language impairment (SLI), ages 8:10 to 12:5 (years; months), to participate in a group negotiation task. Each child interacted with two peers to select toys that children their age would enjoy. Performance was compared to both chronological age-similar (CS) peers and language similar (LS) peers performing the same task. Analyses of the resulting interactions indicated that subjects with SLI produced significantly fewer utterances than the other children in the triad. Similar differences were not observed in the CS or LS triads. Additionally, significantly fewer utterances were addressed to the children …

The Ability Of Children With Specific Language Impairment To Access And Participate In An Ongoing Interaction, Lee Robinson, Martin Fujiki, Julie Campbell Spencer

Faculty Publications

This study investigated the ability of 6 children with specific language impairment (SLI), ages 8;10 to 12;5 (years;months), to enter and participate in an ongoing dyadic interaction. Performance was compared to that of 6 chronological age-matched (CA) peers and 6 language-similar (LS) peers. All children in the LS and CA groups successfully accessed the interaction, and most did so quickly. Two children from the SLI group did not access, and the 4 remaining subjects required varying amounts of time to access. Following successful access, the triadic interactions of subjects were examined. The accessing children with SU talked significantly less, were …

The Effect Of Ultrasonic Frequency Upon Enhanced Killing Ofp. Aeruginosa Biofilms, Zhen Qian, Richard D. Sagers, William G. Pitt Jan 1997

The Effect Of Ultrasonic Frequency Upon Enhanced Killing Ofp. Aeruginosa Biofilms, Zhen Qian, Richard D. Sagers, William G. Pitt

Faculty Publications

It is widely recognized that the bacteria sequestered in a biofilm on a medical implant are much more resistant to antibiotics than their planktonic counterparts. Recent studies have shown that application of antibiotic along with low power ultrasound significantly increases the killing of planktonic bacteria by the antibiotic. Herein is reported a similar application of antibiotic and ultrasound to sessile bacteria in biofilms of Pseudomonas aeruginosa on a polyethylene substrate. Biofilm viability was measured after exposure to 12 μg/ml gentamicin sulfate and 10 mW/cm2 ultrasound at frequencies of 70 kHz, 500 kHz, 2.25 MHz, and 10 MHz. The results …

Two Paradigms For The Market Value Of Liabilities, Robert R. Reitano, Craig B. Merrill Jan 1997

Two Paradigms For The Market Value Of Liabilities, Robert R. Reitano, Craig B. Merrill

Faculty Publications

Financial valuation models can be applied to insurance- related claims. In particular, these models are being employed to calculate the market value of insurance liabilities. The goal of this paper is to introduce the various approaches to valuation that are used in the finance literature and show how the valuation of insurance liabilities fits into the financial valuation framework. The theory suggests that securitization of insurance liabilities may lead to better market value calculations.
