Nullification At Work? A Glimpse From The National Center For State Courts Study Of Hung Juries, Paula Hannaford-Agor, Valerie P. Hans

Faculty Publications

In 1998, the National Institute of Justice awarded a grant to the National Center for State Courts ("NCSC") to examine the frequency and various causes of hung juries. One of the factors that the NCSC project staff investigated was jurors' perceptions of the fairness of the law they were asked to apply in felony trials as well as jury and case characteristics that are often associated with jury nullification. The project also asked judges and other court actors to rate the strength of the evidence in the case. Thus, the project enabled researchers to examine jurors' views, the evidence, and …

The Desert Shall Blossom As The Rose : Pioneering Irrigation / John A. Widtsoe, J. Michael Hunter

Faculty Publications

Beginning in 1847 Mormon pioneers used irrigation or the artificial application of water to land and soil in order to establish an agrarian system in Utah’s sub-humid Salt Lake Valley. Early leaders and members of The Church of Jesus Christ of Latter-day Saints (LDS Church) viewed irrigation as a means of fulfilling the biblical prophecy of Isaiah, “The desert shall rejoice, and blossom as the rose” (Isaiah 35:1), although early pioneers and leaders realized that the Salt Lake Valley was not exactly a desert. In fact, some Mormon leaders described it as a “rich fertile valley.” Although a few Mormon …

Model Checking For Design And Assurance Of E-Business Processes, Bonnie Anderson, James V. Hansen, Paul Benjamin Lowry, Scott L. Summers

Faculty Publications

Use of the Internet for electronic business has the potential to revolutionize the way many businesses are conducted. Yet, several businesses have fallen victim to problems in information systems that facilitate e-Business. These problems are characterized by uncertainties due to system complexity, rapid development, interconnectivity, and a lack of familiarity with the new technologically based economy. This paper demonstrates how model checking can aid in the design and assurance of e- Business processes in environments characterized by distributed processing, parallelism, concurrency, communication uncertainties, and continuous operations.

Automated Rating Of Esl Essays, Deryle W. Lonsdale, Diane Strong-Krause

Faculty Publications

To date, traditional NLP parsers have not been widely successful in TESOLoriented applications, particularly in scoring written compositions. Re-engineering such applications to provide the necessary robustness for handling ungrammatical English has proven a formidable obstacle. We discuss the use of a nontraditional parser for rating compositions that attenuates some of these difficulties. Its dependency-based shallow parsing approach provides significant robustness in the face of language learners’ ungrammatical compositions. This paper discusses how a corpus of L2 essays for English was rated using the parser, and how the automatic evaulations compared to those obtained by manual methods. The types of modifications …

Petrochina Syndrome: Regulating Capital Markets In The Anti-Globalization Era, Stephen F. Diamond

Faculty Publications

To explore this new social fracture and its challenge to the legitimacy of Anglo-American capitalism, this Article presents a case study of the attempt by the Chinese government and major Wall Street investment banks to complete an initial public offering by a major Chinese corporation. Their efforts represented a classic example of the effort to build a new global capitalist order from above without significant concern for the legitimation question. And, as we shall see, the effort was met from below with a vigorous social response. Thus, I suggest that a kind of syndrome, the PetroChina Syndrome if you will, …

Reflections On The Myth Of Icarus In The Age Of Information, Allen S. Hammond Iv

Faculty Publications

It is economics, policy, law, and indeed, for some, religion that advanced information technology should be eventually accessible to the masses. To this end, the federal and state governments are establishing goals and guidelines for advanced information technology's equitable deployment. Chief among the governments' intended beneficiaries are our children, Generations X,Y, Z, and beyond. The explicit expectation, however, is that every individual and group in our society would benefit from such deployment.

Efficiencies in the computer augmented generation, embedded in the processing and storing of information are expected to enhance education, commerce, the economy, political discourse, individual self actualization, and …

Forfeiture By Wrongdoing And Those Who Acquiesce In Witness Intimidation: A Reach Exceeding Its Grasp And Other Problems With Federal Rule Of Evidence 804(B)(6), James F. Flanagan

Faculty Publications

This article is the first comprehensive and critical analysis of the new exception to the hearsay rule that permits prosecutors to admit hearsay statements of absent witnesses when the defendant causes their unavailability at trial. The article develops the problems with the rule's overbroad language, its potential to admit unreliable hearsay and its relationship to the Confrontation Clause. These issues are of increasing interest to lawyers, judges and justices now that it is a federal rule and been adopted by ten states.

The first section is a comprehensive statement of the rule as now applied. The exception is traced from …

Copula Variability In Gullah, Tracey L. Weldon

Faculty Publications

Many researchers have investigated the copula for possible links between African American Vernacular English (aave) and Atlantic Creoles, a connection that has served as the foundation of the Creolist Hypothesis in the on-going debate over the origins of aave. One variety that has been of particular interest in this debate is Gullah, which has been hypothetically linked to aave since some of the earliest statements of the Creolist Hypothesis. To date, however, very little research has been done on copula variability in Gullah itself. This study, therefore, provides an analysis of copula variability in present affirmative contexts in Gullah. Variation …

Study Of Ionic Conductivity Profiles Of The Air Cathode Of A Pemfc By Ac Impedance Spectroscopy, Qingzhi Guo, Maria Cayetana, Yu-Min Tsou, Emory S. De Castro, Ralph E. White

Faculty Publications

A characterization of the ionic conduction of the active layer of a polymer electrolyte membrane fuel cell (PEMFC) cathode by ac impedance measurement at open-circuit potential conditions was conducted. Porous electrode theory was used to derive a compact equation, ∂2Φ̑2/∂y2+∂lnf(y)/∂y×∂Φ̑2/∂y−R/f(y)(1+jΩ)Φ̑2=0, to solve for the impedance response of a cathode at open-circuit potential conditions. This equation includes a parameter R, the ratio of an ionic resistance (evaluated at the active layer/membrane interface), to the total charge-transfer resistance of the active layer. The influence of an assumed ionic conductivity distribution profile f(y) on the error in the estimation of total double-layer …

Synthesis And Characterization Of Mno2-Based Mixed Oxides As Supercapacitors, Hansung Kim, Branko N. Popov

Faculty Publications

Mn/Pb and Mn/Ni mixed oxide were prepared at ambient temperature by reduction of KMnO₄ with Mn, Pb, and Ni salts. This low-temperature approach provides amorphous structure of the active material. The specific capacitance of pure MnO₂ was estimated to be 166 F/g and increased to 210 and 185 F/g for Mn/Ni and Mn/Pb oxides, respectively. The carbon loading was optimized at 20 wt %. Based on a single electrode, the Mn/Ni mixed oxide showed a high rate capability of 3.12 Wh/kg at constant power discharge of 1 kW/kg.

Corrosion Protection Of Steel Using Nonanomalous Ni-Zn-P Coatings, Basker Veeraraghavan, Bala Haran, Swaminatha P. Kumaraguru, Branko N. Popov

Faculty Publications

A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content (74 wt % as compared to 15-20 wt % in the conventional plating method) has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO₄, complexing agent and ammonium chloride. Varying the concentration of ZnSO₄ in the bath controls the final amount of Zn in the deposit. The Zn content in the coating was optimized based on the corrosion resistance of the final deposit. Coatings with 16.2 …

Full Cell Mathematical Model Of A Mcfc, N. Subramanian, B. S. Haran, Ralph E. White, Branko N. Popov

Faculty Publications

A theoretical model for the molten carbonate fuel cell was developed based on the three-phase homogeneous approach. Using this model, the contribution of different cell components to losses in cell performance has been studied. In general, at low current densities, the electrolyte matrix contributed to the major fraction of potential losses. Mass transfer effects became important at high current densities and were more prominent at the cathode. Electrolyte conductivity and cathode exchange current density seemed to play a limiting role in determining cell performance. Using the model, the maximum power density from a single cell for different cell thicknesses was …

Thermally Stable Gel Polymer Electrolytes, Min-Kyu Song, Young-Taek Kim, Yong Tae Kim, Byung Won Cho, Branko N. Popov, Hee-Woo Rhee

Faculty Publications

To prepare miscible polyethylene glycol diacrylate/polyvinylidene fluoride (PEGDA/PVdF) blend gel polymer electrolytes, low molecular weight (M = 742) liquid PEGDA oligomer was mixed with PVdF-HFP dissolved in ethylene carbonate/dimethyl carbonate/LiPF₆ liquid electrolytes, and then cured under ultraviolet irradiation. Room temperature conductivity of PEGDA/PVdF blend films was found to be comparable to that of PVdF-HFP gel polymer electrolytes, and they were electrochemically stable up to 4.6 V vs. Li/Li⁺. Scanning electron micrographs revealed that PEGDA/PVdF blend electrolytes have pore size intermediate between dense PEGDA and highly porous PVdF-HFP. It was confirmed by weight change measurement that liquid electrolyte …

Development Of A Novel Electrochemical Method To Deposit High Corrosion Resistant Silicate Layers On Metal Substrates, Basker Veeraraghavan, Bala Haran, Dragan Slavkov, Swaminatha Prabhu, Branko N. Popov, Bob Heimann

Faculty Publications

A novel method for electrodepositing silicates on metallic substrates from aqueous solutions has been developed. The technique is demonstrated by forming a passive film on galvanized steel. The silicate layer was deposited cathodically from a bath containing PQ Corporation N sodium silicate solution (3.22 weight ratio sodium silicate, 37.5% solution in water). A post-treatment drying process increased the Si content in the coating and improved the corrosion characteristics of the silicate layer. Deposition parameters like bath concentration and temperature have been optimized using corrosion characteristics and surface morphology of the final coating. Finally, stability studies show that the silicate coatings …

Polyetheretherketone Membranes For Elevated Temperature Pemfcs, Balasubramanian Lakshmanan, Wayne Huang, David Olmeijer, John W. Weidner

Faculty Publications

Membrane electrode assemblies ~MEAs! made from polyetheretherketone ~PEEK! showed excellent fuel cell performance and thermal stability in the presence of substantial CO at elevated temperatures ~i.e., 120°C! in proton exchange membrane fuel cells ~PEMFCs!. For example, the current from a MEA made from PEEK membrane at 0.6 V and 120°C was 0.50 A/cm2 when run on pure hydrogen and 0.45 A/cm2 when run on reformate ~50% H2 , 1300 ppm CO, and balance N2). The current density from a MEA made from Nafion at 0.6 V and 120°C was 0.61 A/cm2 when run on pure hydrogen. The main difference between …

Consensus Software: Robustness And Social Good, Michael N. Huhns

Faculty Publications

In this column I explore some far-reaching issues of software development that lie at the intersection of robust software and sociopolitical systems. These two areas might seem unrelated-and most software developers would likely be horrified to have politics intrude on their programming efforts-but the intersection occurs through these premises: software systems administer and control much of our societal infrastructure; people would appreciate and better accept that control if they had input into the nature of the control and the systems' behavior; designers can make software systems more robust through redundancy, in which different versions of software components might cover for …

Being And Acting Rational, Michael N. Huhns

Faculty Publications

Rationality alone is insufficient to specify agent design. Using economic theory, we can program agents to behave in ways that maximize their utility while responding to environmental changes. However, economic models for agents, although general in principle, are typically limited in practice because the value functions that are tractable essentially reduce an agent to acting selfishly. Building a stable social system from a collection of agents motivated by self-serving interests is difficult. Finally, understanding rationality and knowledge requires interdisciplinary results from artificial intelligence, distributed.

Earned Sovereignty: Juridical Underpinnings, Michael P. Scharf

Faculty Publications

This piece is the second in a trilogy of three simultaneously published articles in the Denver Journal of International Law that examine the emerging doctrine of "earned sovereignty," a concept that seeks to reconcile the principles of self-determination and humanitarian intervention with the principles of sovereignty and territorial integrity. This article sets forth the legal underpinnings for the doctrine, while the other two articles in the trilogy provide its policy foundations, and apply the doctrine to several modem case studies. Together, the three articles are the product of the Public International Law and Policy Group's "Intermediate Sovereignty Project," sponsored by …
