Book Review: Bennett Explains Arbitration Fundamentals, Without The Legalese, Amy J. Schmitz

Faculty Publications

At the outset of the book, Steven Bennett expresses "fervent hope that this book will be of use to lawyers, law students and business people interested in learning the fundamentals of arbitration law." The book therefore focuses on fundamental, or basic, arbitration concepts and norms. It does not purport to provide in-depth discussion and analysis of arbitration law, but instead serves as a shelf reference or primer that promises to achieve Bennett's goal.

I Am/Was The Walrus, Daniel Beller-Mckenna

Faculty Publications

For most of his adult life, John Lennon fought to define himself against his public identity as "Beatle-:John." That image, crafted by the Beatles' manager Brian Epstein and the pop music industry became a burden to all four of the Beatles during the group's seven years of international star-dom. In place of the rough leather-clad rock and roll band that played rambling one hour sets in the Hamburg Kaiserkeller and the Liverpool Cavern Club during 1960-61, Epstein forged a more commercially viable group of four well (and uniformly) dressed young men whose stage act was reduced to twenty minute carefully …

The Nature Of Interchain Excitations In Conjugated Polymers: Spatially-Varying Interfacial Solvatochromism Of Annealed Meh-Ppv Films Studied By Near-Field Scanning Optical Microscopy (Nsom), Richard D. Schaller, Lynn F. Lee, Justin C. Johnson, Louis H. Haber, Richard J. Saykally, John Vieceli, Ilan Benjamin, Thuc Quyen Nguyen, Benjamin J. Schwartz

Faculty Publications

The nature of interchain excitations in conjugated polymers was discussed. The spatially-varying solvatochromism of annealed poly(2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) films were studied by near-field scanning optical microscopy (NSOM). The solvatochromic spectral shifts of the interfacial luminescence were measured as a function of solvent polarity. The results were analyzed with an interfacial dielectric continuum model to determine the dipole moment of emissive excited states.

The Rhetoric And Promises Of Accountability (Lecture), Melvin J. Dubnick

Faculty Publications

This document discusses the conceptual challenges, historical roots, and cultural ambiguities of the term “accountability” and advocates for its careful reexamination and preservation in modern governance.

Little Qualitative Rna Misexpression In Sterile Male F1 Hybrids Of Drosophila Pseudoobscura And D. Persimilis, Jane Reiland, Mohamed A.F. Noor

Faculty Publications

Background: Although the genetics of hybrid sterility has been the subject of evolutionary studies for over sixty years, no one has shown the reason(s) why alleles that operate normally within species fail to function in another genetic background. Several lines of evidence suggest that failures in normal gene transcription contribute to hybrid dysfunctions, but genome-wide studies of gene expression in pure-species and hybrids have not been undertaken. Here, we study genome-wide patterns of expression in Drosophila pseudoobscura, D. persimilis, and their sterile F1 hybrid males using differential display. Results: Over five thousand amplifications were analyzed, and 3312 were present in …

Comparative Proteome Analysis Of Brucella Melitensis Vaccine Strain Rev 1 And A Virulent Strain, 16m, Michel Eschenbrenner, Mary Ann Wagner, Troy A. Horn, Jo Ann Kraycer, Cesar V. Mujer, Sue Hagius, Philip Elzer, Vito G. Delvecchio

Faculty Publications

The genus Brucella consists of bacterial pathogens that cause brucellosis, a major zoonotic disease characterized by undulant fever and neurological disorders in humans. Among the different Brucella species, Brucella melitensis is considered the most virulent. Despite successful use in animals, the vaccine strains remain infectious for humans. To understand the mechanism of virulence in B. melitensis, the proteome of vaccine strain Rev 1 was analyzed by two-dimensional gel electrophoresis and compared to that of virulent strain 16M. The two strains were grown under identical laboratory conditions. Computer-assisted analysis of the two B. melitensis proteomes revealed proteins expressed in either 16M …

Inhibition Of Amyloid-Β Aggregation And Caspase-3 Activation By The Ginkgo Biloba Extract Egb761, Yuan Luo, Julie V. Smith, Vijaykumar Paramasivam, Adam Burdick, Kenneth J. Curry, Justin P. Buford, Ikhlas Khan, William J. Netzer, Huaxi Xu, Peter Butko

Faculty Publications

Standardized extract from the leaves of the Ginkgo biloba tree, labeled EGb761, has been used in clinical trials for its beneficial effects on brain functions, particularly in connection with age-related dementias and Alzheimer's disease (AD). Substantial experimental evidence indicates that EGb761 protects against neuronal damage from a variety of insults, but its cellular and molecular mechanisms remain unknown. Using a neuroblastoma cell line stably expressing an AD-associated double mutation, we report that EGb761 inhibits formation of amyloid-β (Aβ) fibrils, which are the diagnostic, and possibly causative, feature of AD. The decreased Aβ fibrillogenesis in the presence of EGb761 was observed …

Captain Moroni's Wartime Strategies: An Application For The Spiritual Battles Of Our Day, Richard J. Mcclendon

Faculty Publications

As Mormon abridged the Nephite record he included what he deemed most relevant for latter-day Israel including stories of war. The so-called war chapters provide a rich resource of modern-day spiritual applications for teachers and students of the gospel (see Alma 43-62). One way to apply these chapters is to draw a parallel between the physical and the spiritual between Moroni's physical battles on the field and the spiritual battles that we face in our own lives today. To be more specific we might ask these questions: (1) What strategies did Captain Moroni use to prepare and protect himself and …

Seeking Salvation For Accountability, Melvin J. Dubnick

Faculty Publications

This is a paper in defense of a concept that is threatened by its popularity and undermined by those who use it most. It is a call for a reexamination and reaffirmation of “accountability” from the perspective of its central role in modern governance. It is a plea for saving the concept of accountability from the abuses it suffers in the hands of friends and advocates. It is an effort at salvation for a concept that has lost its meaningful “soul” in a world filled with rhetoricians, reformers, and functionalists – all well intentioned, but each contributing to accountability’s fall …

Investigating The Mechanism Of Acoustically Activated Uptake Of Drugs From Pluronic Micelles, Ghaleb A. Husseini, Christopher M. Runyan, William G. Pitt

Faculty Publications

Background

This paper examines the mechanism of ultrasonic enhanced drug delivery from Pluronic micelles. In previous publications by our group, fluorescently labeled Pluronic was shown to penetrate HL-60 cells with and without the action of ultrasound, while drug uptake was increased with the application of ultrasound.

Methods

In this study, the amount of uptake of two fluorescent probes, Lysosensor Green (a pH-sensitive probe) and Cell Tracker Orange CMTMR (a pH-independent probe), was measured in HL-60 and HeLa cells.

Results

The results of our experiments show that the increase in drug accumulation in the cells as a result of ultrasonication is …

A Metadata Approach To Preservation Of Digital Resources: The University Of North Texas Libraries' Experience, Daniel Gelaw Alemneh, Samantha K. Hastings, Cathy Hartman

Faculty Publications

Preserving long-term access to digital information resources is one of the key challenges facing libraries and information centers today. The University of North Texas (UNT) Libraries has entered into partnership agreements with federal and state agencies to ensure permanent storage and public access to a variety of government information sources. As digital resource preservation encompasses a wide variety of interrelated activities, the UNT Libraries are taking a phased approach to ensure the long-term access to its digital resources. Formulation of preservation policy and creation of preservation metadata for electronic files and digital collections are among the most important steps. This …

Density Profile And Flow Of Miscible Fluid With Dissimilar Constituent Masses, Ras B. Pandey, D. Stauffer, R. Seyfarth, Luis A. Cueva, J.F. Gettrust, Warren Wood

Faculty Publications

A computer simulation model is used to study the density profile and flow of a miscible gaseous fluid mixture consisting of differing constituent masses (m(A) = m(B)/3) through an open matrix. The density profile is found to decay with the height proportional to exp(-m(A(B))h), consistent with the barometric height law. The flux density shows a power-law increase proportional to (p(c) - p)(a) with mu similar or equal to 2.3 at the porosity 1 - p above the pore percolation threshold 1 - p(c).

May Harvey Rest In Peace: Lakin V. Postal Life And Casualty Company, Robert H. Jerry Ii

Faculty Publications

More than a quarter-century has passed since I entered law school as a first-year student and began what has become a career of reading, among other things, cases. I cannot even guess the number of cases I have read in the ensuing years. Most of them have been fairly ordinary, but many have been wonderful for one reason or another. Because I hope to read at least as many cases during my next twenty-five years (or more) of legal study, I am not yet ready to crown any particular case with the title of "my favorite," "the most significant," or …

Relaxation Through Homogenization For Optimal Design Problems With Gradient Constraints, R. Lipton

Faculty Publications

The problem of the relaxation of optimal design problems for multiphase composite structures in the presence of constraints on the gradient of the state variable is addressed. A relaxed formulation for the problem is given in the presence of either a finite or infinite number of constraints. The relaxed formulation is used to identify minimizing sequences of configurations of phases.

Interdisciplinarity: The Road Ahead For Education In Digital Libraries, Anita Coleman

Faculty Publications

This article reviews the state of education in digital libraries and curriculum planning documents from professional associations in two areas: Library and Information Science; and Computing. It examines suggestions for integration and interdisciplinarity in education for digital libraries curricula using definitions of a discipline, interdisciplinarity, and the transdisciplinary structure of a university in order to discover how such integration may be successfully accomplished. A plan to use learning communities and develop an interdisciplinary curriculum for Knowledge Organization is briefly discussed.

N Uptake As A Function Of Concentration In Streams, Walter K. Dodds, Amanda J. Lopez, William B. Bowden, Stan Gregory, Nancy B. Grimm, Stephen K. Hamilton, Anne E. Hershey, Eugenia Marti, William H. Mcdowell, Judy L. Meyer, Donna Morrall, Patrick J. Mulholland, Bruce J. Peterson, Jennifer L. Tank, H. Maurice Valett, Jackson R. Webster, Wilfred M. Wollheim

Faculty Publications

Detailed studies of stream N uptake were conducted in a prairie reach and gallery forest reach of Kings Creek on the Konza Prairie Biological Station. Nutrient uptake rates were measured with multiple short-term enrichments of NO3− and NH4+ at constant addition rates in the spring and summer of 1998. NH4+ uptake was also measured with 15N-NH4+ tracer additions and short-term unlabeled NH4+ additions at 12 stream sites across North America. Concurrent addition of a conservative tracer was used to account for dilution in all experiments. NH4+ uptake rate per unit area (Ut) was positively correlated to nutrient concentration across all …

Nanofatigue Studies Of Ultrathin Hard Carbon Overcoats Used In Magnetic Storage Devices, Xiaodong Li, Bharat Bhushan

Faculty Publications

A technique to perform nanofatigue experiments was developed. This technique utilizes a depth-sensing nanoindenter with harmonic force. The nanofatigue behavior of 20 nm thick amorphous carbon coatings was studied. The contact stiffness was monitored continuously throughout the test. The abrupt decrease in the contact stiffness indicates fatigue damage has occurred. The critical load amplitude, below which no fatigue damage occurs, was identified. It was found that the filtered cathodic arc coating exhibits longer fatigue life than a direct ion beam coating. Failure mechanisms of the coatings during fatigue are also discussed in conjunction with the hardness,elastic modulus, and fracture toughness, …

Geochemistry Of Atmospheric Aerosols Generated From Lava-Seawater Interactions, Francis J. Sansone, Claudia R. Benitez-Nelson, Joseph A. Resing, Eric H. Decarlo, Sue M. Vink, Jacqueline A. Heath, Barry J. Huebert

Faculty Publications

[1] Trace elements were measured in the aerosol plume produced by lava‐seawater interactions along the shoreline of Kilauea volcano, Hawaii. Plume concentrations were normalized relative to Hawaiian basalt composition and showed a linear log‐log co‐variation with their emanation coefficient (an indicator of element volatility). Normalized aerosol concentrations also consistently covaried with corresponding normalized concentrations in dilute fumarolic gas from Kilauea volcano and fumarolic gas condensates from Kudryavy and Merapi volcanoes, despite different mechanisms of element volatilization. Conservatively estimated regional ocean deposition rates of Cu, Cd, Ni, Pb, Mn, Zn, Fe and P were >50 times background rates. Thus, upper ocean …

But Can You Count On Them To Be Ethical?, Melvin J. Dubnick, Jonathan B. Justice

Faculty Publications

The issue addressed in this paper is whether the linkage between accountability and ethics makes sense in light of what we know about social and psychological behavior. And if the connection between the two makes analytic sense, what are the implications of those linkages for our understanding of public administrative ethics? We will show that there is indeed (at the least) an analytic connection between accountability and ethics, and that the relationship is a complex one rooted in the fact that accountability is itself takes multiple and relatively distinct forms in the lives of public administrators. Furthermore, we contend that …

The Effect Of Reactor Geometry On Frontal Polymerization Spin Modes, John A. Pojman, Jonathan Masere, Enrico Petretto, Mauro Rustici, Do-Sung Huh, Min Suk Kim, Vladimir Volpert

Faculty Publications

Using reactors of different sizes and geometries the dynamics of the frontal polymerization of 1,6-hexanediol diacrylate (HDDA) and pentaerythritol tetraacrylate (PETAC), with ammonium persulfate as the initiator were studied. For this system, the frontal polymerization exhibits complex behavior that depends on the ratio of the monomers. For a particular range of monomers concentration, the polymerization front becomes nonplanar, and spin modes appear. By varying the reactor diameter, we experimentally confirmed the expected shift of the system to a greater number of "hot spots" for larger diameters. For square test tubes a "zig-zag" mode was observed for the first time in …
