Access To Justice For The Self-Represented Litigant: An Interdisciplinary Investigation By Designers And Lawyers, Ronald W. Staudt, Paula Hannaford-Agor

Faculty Publications

To assist courts, the National Center for State Courts, in partnership with the Illinois Institute of Technology's Institute of Design and the Chicago-Kent College of Law, launched a research project to examine court processes and recommend modifications to eliminate or reduce procedural barriers to access for self-represented litigants. The projects had three major tasks: (1) to identify major barriers to access to justice that self-represented litigants encounter due to court procedures and administrative requirements; (2) to employ system design methodology to redesign court processes to remove those barriers, and (3) to translate the conceptual model for redesigned court system into …

Vibrato Rate Adjustment, Christopher Dromey, Neisha Carter, Arden Hopkin

Faculty Publications

Summary: The goal of the present study was to document the acoustic changes that occur as singers attempt to increase or decrease their vibrato rate to match target stimuli. Eight advanced singing students produced vowels with vibrato in three registers, both naturally and while attempting to match faster or slower rate stimuli. Slower rates were associated with lower intensity and less steady vibrato. Faster rates involved increased vibrato extent in the chest register and increased intensity in the head register. Singers whose spontaneous vibrato rates were naturally either slower or faster tended to also be relatively slower or faster when …

Are Plurals Derived Or Stored?, David Eddington, Patricia Lestrade

Faculty Publications

The ability to produce and comprehend human language involves at least two processes: the storage of units and the computations performed on those units. The role that storage and computation play in the processing of inflectional morphology is highly debated. At one end of the spectrum is the full storage model, which holds that all known words, whether morphologically complex or not, have separate entries in the mental lexicon (Jackendoff 1975, Manelis and Tharp 1977, Butterworth 1983, Bybee 1985, 1988, Rumelhart and McClelland 1986, McClelland 1988, Stemberger 1994, Rueckl, Mikolinski, Raveh, Miner, and Mars 1997). This position puts an enormous …

Glorious Reality: Presidential Fretting About The Alan Workshop, Chris Crowe

Faculty Publications

Reality is cruel.

When I was nominated to run for president of ALAN, I was flattered and briefly entertained dreams of grandeur. If I were lucky enough to win, I thought, my friends, family, and colleagues would be so very proud. If I won, I dreamed, I would be lavished with presidential perks and presents. If I became president of ALAN, I imagined, I would get to wallow in the glory of presiding over a glorious ALAN Workshop.

So far, this is what reality has taught me:

Proud? My local friends, family, and colleagues barely even noticed when the election …

Differences Of Opinion And The Cross Section Of Stock Returns, Karl B. Diether, Christopher J. Malloy, Anna Scherbina

Faculty Publications

We provide evidence that stocks with higher dispersion in analysts' earnings forecasts earn lower future returns than otherwise similar stocks. This effect is most pronounced in small stocks and stocks that have performed poorly over the past year. Interpreting dispersion in analysts' forecasts as a proxy for differences in opinion about a stock, we show that this evidence is consistent with the hypothesis that prices will reflect the optimistic view whenever investors with the lowest valuations do not trade. By contrast, our evidence is inconsistent with a view that dispersion in analysts' forecasts proxies for risk.

A Cross-Firm Analysis Of The Impact Of Corporate Governance On The East Asian Financial Crisis, Todd Mitton

Faculty Publications

In a sample of 398 firms from Indonesia, Korea, Malaysia, the Philippines, and Thailand, firm-level differences in variables related to corporate governance had a strong impact on firm performance duringthe East Asian financial crisis of 1997–1998. Significantly better stock price performance is associated with firms that had indicators of higher disclosure quality (ADRs and auditors from Big Six accounting firms), with firms that had higher outside ownership concentration, and with firms that were focused rather than diversified. The results suggest that individual firms have some power to preclude expropriation of minority shareholders if legal protection is inadequate.

The Role Of Outdoor Recreation In Family Enrichment, Patti A. Freeman, Ramon B. Zabriskie

Faculty Publications

The family is the fundamental unit in society and perhaps the oldest and most important of all human institutions. Several studies have indicated a positive correlation between strong, successful families and family participation in outdoor recreational activities. This paper addresses the role of structured outdoor recreation programming in family enrichment. Findings from two studies based in the United States are presented: one on the effect of a one–day family outdoor adventure program on parental and child perceptions of family functioning and the other from a qualitative inquiry into the meaning of family residential camping experiences. The first study collected both …

Surface Micromachined Force Gauges: Uncertainty And Reliability, Jonathan W. Wittwer, Troy Gomm, Larry L. Howell

Faculty Publications

Surface micromachining of micro-electro-mechanical systems (MEMS), like all other fabrication processes, has inherent variation that leads to uncertain material and dimensional parameters. By considering the effects of these variations during the design of micro force gauges, the gauge uncertainty and reliability can be estimated. Without means of calibrating micro gauges, these effects are often significant when compared to experimental repeatability. The general force gauge model described in this paper can be used to measure a wide range of forces, and simple design changes can lead to improved accuracy in measurement. A method of probabilistic design is described that is not …

Origins And Meanings Of The Public Domain, Tyler T. Ochoa

Faculty Publications

This article surveys the history and development of the public domain in intellectual property law. The public domain has existed since time immemorial, and was first recognized in the Statute of Monopolies and the Statute of Anne, which placed time limits on patents and copyrights, after which the invention or work could be copied freely by anyone. The concept was enshrined in the U.S.Constitution and reflected in American patent and copyright laws. Before 1896, courts referred to matter not protected by patent or copyright law as "public property" or "common property. " In 1896,the U.S. Supreme Court imported the term …

Water Transport In Polymer Electrolyte Membrane Electrolyzers Used To Recycle Anhydrous Hcl: I. Characterization Of Diffusion And Electro-Osmotic Drag, Sathya Motupally, Aaron J. Becker, John W. Weidner

Faculty Publications

In this paper, diffusion and electro-osmotic drag of water across Nafion® membranes in the presence of HCl are characterized. For all the measurements, one side of the Nafion membrane was in contact with liquid water and the other side with gaseous anhydrous HCl. To characterize diffusion of water, the open-circuit flux of water across a catalyst-coated Nafion 115 membrane was measured as a function of HCl flow rate and temperature at a constant cell pressure of 1 atm. Due to the nature of varying driving force for diffusion as a function of HCl flow rate, the experimental data was analyzed …

Development Of A Novel Co Tolerant Proton Exchange Membrane Fuel Cell Anode, Andrew T. Haug, Ralph E. White, John W. Weidner, Wayne Huang

Faculty Publications

Typically Pt is alloyed with metals such as Ru, Sn, or Mo to provide a more CO-tolerant, high-performance proton exchange membrane fuel cell (PEMFC) anode. In this work, a layer of carbon-supported Ru is placed between the Pt catalyst and the anode flow field to form a filter. When oxygen is added to the fuel stream, it was predicted that the slow H₂ kinetics of Ru in this filter would become an advantage compared to Pt and Pt:Ru alloy anodes, allowing a greater percentage of O₂ to oxidize adsorbed CO to CO₂. With an anode feed …

Studies On Capacity Fade Of Spinel-Based Li-Ion Batteries, Ramadass Premanand, Anand Durairajan, Bala Haran, Ralph E. White, Branko N. Popov

Faculty Publications

The performance of Cell-Batt^® Li-ion cells using nonstoichiometric spinel as the positive electrode material has been studied at different charging rates. The capacity of the cell was optimized based on varying the charging current and the end potential. Subsequent to this, the capacity fade of these batteries was studied at different charge currents. During cycling, cells were opened at intermittent cycles and extensive material and electrochemical characterization was done on the active material at both electrodes. For all charge currents, the resistance of both the electrodes does not vary significantly with cycling. This result is in contrast with cells …

Modeling The Effects Of Ion Association On Alternating Current Impedance Of Solid Polymer Electrolytes, Changqing Lin, Ralph E. White, Harry J. Ploehn

Faculty Publications

This work presents a rigorous continuum model describing the transport of ions and associated ion pairs in solid polymer electrolytes subjected to small amplitude alternating current (ac) excitation. The model treats ion association as a reversible reaction among ions and ion pairs. Dimensionless governing equations are developed from component mass balances, flux equations based on dilute solution theory, and the Poisson equation. Assuming reversible electrode reactions and electroneutrality, the model equations have an analytical solution. Further simplifications are possible in limiting cases (weak and strong association, zero and infinite frequency excitation), giving expressions consistent with previously published models. We use …

Weaving A Computing Fabric, Michael N. Huhns, Larry M. Stevens, John W. Keele, Jim E. Wray, Warren M. Snelling, Greg P. Harhay, Randy R. Bradley

Faculty Publications

As sources of information relevant to a particular domain proliferate, we need a methodology for locating, aggregating, relating, fusing, reconciling, and presenting information to users. Interoperability thus must occur not only among the information, but also among the different software applications that process it. Given the large number of potential sources and applications, interoperability becomes an extremely large problem for which manual solutions are impractical. A combination of software agents and ontologies can supply the necessary methodology for interoperability.

Agents As Web Services, Michael N. Huhns

Faculty Publications

Web services are extremely flexible. Most advantageously, a developer of Web services need not know who or what will use the services being provided. The paper discusses current standards for Web services, directory services and the Semantic Web. It considers how agents extend Web services in several important ways.

Agent Societies: Magnitude And Duration, Michael N. Huhns

Faculty Publications

If you only need agents to search the Web for cheap CDs, scalability is not an issue. The Web can support numerous agents if each acts independently. In short order, however, billions of embedded agents that sense their environment and interact with us and other agents will fill our world, making the human environment friendlier and more efficient. These agents will need not only scalable infrastructures and communication services, but also scalable social services encompassing ethics and laws. Research projects are under way around the world to develop and deploy such services. The author takes a look at the critical …

Reparations And The Colonial Dilemma: The Insurmountable Hurdles And Yet Transformative Benefits, Ediberto Román

Faculty Publications

The Seventh Annual Latina and Latino Critical Race Theory ("LatCrit") Conference held in May 2002 at the University of Oregon, not unlike other efforts in the movement, addressed a panoply of challenging, provocative, and controversial issues. Perhaps one the most intellectually interesting and yet troubling panels addressed reparations for the inhabitants of United States' colonial territories. Specifically, the panel was titled "Reparations, Redress, and Remedies: Undoing the Legacy of Colonialism and Imperialism." Members of the academy as well as a representative of Puerto Rico's Independence Party participated in a lively discussion and debate. Although the articles resulting from this panel …
