Design And Synthesis Of A New Class Of Twin-Chain Amphiphiles For Self-Assembled Monolayer-Based Electrochemical Biosensor Applications, Thomas J. Fisher, Socrates Jose P. Cañete, Rebecca Lai, Patrick Dussault

Patrick Dussault Publications

A new class of twin-chain hydroxyalkylthiols (mercaptoalkanols) featuring a nearly constant cross-section and the potential for modification of one or both termini are available with complete regioselectivity through Pd-mediated couplings of benzene diiododitriflate, including an example of a previously unreported coupling to generate an ortho-substituted arene bis acetic acid. Selfassembled monolayers (SAMs) prepared from the new amphiphiles demonstrate improved stability in an electrochemical sensor system compared with monolayers prepared from analogous single chain thiols.

Synthesis Of Alkyl Hydroperoxides Via Alkylation Of Gem-Dihydroperoxides, Shivakumar Kyasa, Benjamin W. Puffer, Patrick Dussault

Patrick Dussault Publications

Two-fold alkylation of 1,1-dihydroperoxides, followed by hydrolysis of the resulting bisperoxyacetals, provides a convenient method for synthesis of primary and secondary alkyl hydroperoxides.

Tandem Application Of C-C Bond-Forming Reactions With Reductive Ozonolysis, Rachel Willand-Charnley, Patrick Dussault

Patrick Dussault Publications

Several variants of reductive ozonolysis, defined here as the in situ generation of aldehydes or ketones during ozonolytic cleavage of alkenes, are demonstrated to work effectively in tandem with a number of C-C bond-forming reactions. For reactions involving basic nucleophiles (1,2- addition of Grignard reagents, Wittig or Horner-Emmons olefinations, and directed Aldol reactions of lithium enolates) the one-pot process offers a rapid and high-yielding alternative to traditional two-step protocols.

International Law In A Time Of Scarcity: An Introduction, Harlan G. Cohen

Faculty Scholarship

Stories of scarcity litter the morning newspapers. Around the world, resources — food, water, fuel sources, clean air — seem stretched to, or even beyond, capacity. Consequences have already been serious, including suffering and unrest. Competition for resources seems likely only to increase. Does international law have the tools to manage or even solve this growing global problem? It was with this question in mind that the editors of the Georgia Journal of International and Comparative Law convened their 2012 symposium: “International Law in a Time of Scarcity.”

This short essay serves as introduction to that symposium and the related …

Lawyers And Precedent, Harlan G. Cohen

Faculty Scholarship

Despite common references to the “invisible college of international lawyers,” and the doctrinal role granted to “the most highly qualified publicists of the various nations,” the role of lawyers, as lawyers, in the creation, development, and maintenance of the international legal order remains oddly underexplored. This short essay, prepared as part of a symposium on “The Role of Non-State Actors in International Law,” explores the role of lawyers as independent actors within international law. It argues that focusing on lawyers can help provide insights into how international law develops — specifically here, how and why a practice of precedent seems …

Wireless Localism: Beyond The Shroud Of Objectivity In Federal Spectrum Administration, Olivier Sylvain

Faculty Scholarship

Recent innovations in mobile wireless technology have instigated a debate between two camps of legal scholars about how policymakers should structure federal administration of the electromagnetic spectrum. The first argues that the Federal Communications Commission should define spectrum use rights more clearly and give spectrum licensees near fee-simple property rights in frequencies that they can use and sell in secondary markets as they wish. The second camp argues that, rather than award exclusive licenses to the highest bidder, the FCC ought to open much if not most of the spectrum to unlicensed use by smartphones and tablets equipped with the …

Oasis Or Mirage: The Supreme Court's Thirst For Dictionaries In The Rehnquist And Roberts Eras, James J. Brudney, Lawrence Baum

Faculty Scholarship

The Supreme Court’s use of dictionaries, virtually non-existent before 1987, has dramatically increased during the Rehnquist and Roberts Court eras to the point where as many as one-third of statutory decisions invoke dictionary definitions. The increase is linked to the rise of textualism and its intense focus on ordinary meaning. This Article explores the Court’s new dictionary culture in depth from empirical and doctrinal perspectives. We find that while textualist justices are heavy dictionary users, purposivist justices invoke dictionary definitions with comparable frequency. Further, dictionary use overall is strikingly ad hoc and subjective. We demonstrate how the Court’s patterns of …

Cluster Ensemble-Based Image Segmentation, Xiaoru Wang, Junping Du, Shuzhe Wu, Xu Li, Fu Lo

Electrical and Computer Engineering Faculty Publications and Presentations

Image segmentation is the foundation of computer vision applications. In this paper, we propose a new cluster ensemble-based image segmentation algorithm, which overcomes several problems of traditional methods. We make two main contributions in this paper. First, we introduce the cluster ensemble concept to fuse the segmentation results from different types of visual features effectively, which can deliver a better final result and achieve a much more stable performance for broad categories of images. Second, we exploit the PageRank idea from Internet applications and apply it to the image segmentation task. This can improve the final segmentation results by combining …

Review Of A Thousand Deer: Four Generations Of Hunting And The Hill Country By Rick Bass., Scott Slovic

Great Plains Quarterly (through 2013)

Known typically as a writer from Texas and Montana, or simply as one of the greatest contemporary American environmental writers, Rick Bass can certainly be considered “a writer of the greater Great Plains,” the region stretching from the prairie near the Gulf of Mexico to the Rocky Mountain foothills of the inland Northwest. The twelve essays collected in A Thousand Deer span the twenty-year period from 1991 to 2011, with most of them having appeared in such publications as Texas Monthly or Texas Parks and Wildlife during the past decade. One piece, “The Silent Language,” is published in this book …

“Ever Since The Hanging Of Oliphant” Lynching And The Suppression Of Mob Violence In Topeka, Kansas, Brent M.S. Campney

Great Plains Quarterly (through 2013)

“The most remarkable scene ever enacted in the heart of a great city was witnessed in Topeka last night, in the final act of the tragedy on which the curtain rose with the sunrise yesterday,” reported the Topeka Daily Capital on June 5, 1889. “Twelve hours after the spirit of Alonzo T. Rodgers had taken its flight, his murderer was hung in the very center of the capital city, under the broad glare of the electric light and by a body of ‘vigilantes’ which in its composition was equalled by no other in all the history of the western world.” …

Review Of Island Of Bones: Essays By Joy Castro, Patricia Foster

Great Plains Quarterly (through 2013)

With the lyric vision of a poet, the dramatic tension of a novelist, and the meditative commentary of an essayist, Joy Castro has crafted a remarkable book of linked essays about the multiple border crossings of identity. In the book’s title essay, “Island of Bones,” the narrator ruptures the myths of the mainstream Cuban American narrative (her family immigrated not to Miami after Fidel Castro’s revolution but to Key West in the 1870s; worshiped not in Catholic cathedrals but in the Kingdom Halls of the Jehovah’s Witnesses; earned money not through investments but as “cleaners of other people’s houses, grocery …

Family, Ethnic Entrepreneurship, And The Lebanese Of Kansas, Jay M. Price, Sue Abdinnour

Great Plains Quarterly (through 2013)

As they entered the elegant lobby of the Waldorf Astoria, Elias G. Stevens and his wife, Handuma, must have marveled at how their lives turned out. They had both been born and raised in what was once the Ottoman province of Syria. They had come to the United States at the turn of the century, found their way to Wichita, Kansas, and worked hard to build a successful candy and tobacco business. They were in New York to meet with representatives from Philip Morris. Surveying the accommodations, however, Handuma noticed a major problem that had to be addressed right away. …

Review Of Light On The Prairie: Solomon D. Butcher, Photographer Of Nebraska’S Pioneer Days By Nancy Plain, M. Melissa Wolfe

Great Plains Quarterly (through 2013)

In 1886, Custer County photographer Solomon Butcher conceived a plan to create a photographic history of the pioneer era of the county. Though his dream never made him the fortune he had hoped, it did result, in 1913, in the deposit of more than 3,000 glass-plate negatives with the Nebraska State Historical Society. It can be readily argued that in the century since this time, no other photographs have become as ubiquitous in histories of the American West. And yet, in comparison, very little has been written on these photographs explicitly or on their maker. Nancy Plain’s Light on the …

Language, Legal Origins, And Culture Before The Courts: Cross-Citations Between Supreme Courts In Europe, Martin Gelter, Mathias M. Siems

Faculty Scholarship

Should courts consider cases from other jurisdictions? The use of foreign law precedent has sparked considerable debate in the United States, and this question is also controversially discussed in Europe. In this article and within the larger research project from which it has developed, we study the dialogue between different European supreme courts quantitatively. Using legal databases in Austria, Belgium, England and Wales, France, Germany, Ireland, Italy, the Netherlands, Spain, and Switzerland, we have hand-collected a dataset of transnational citations between the highest courts of these countries for the time between 2000 and 2007. In the present article we show …

A Wildfire Risk Assessment Framework For Land And Resource Management, Joe H. Scott, Matthew P. Thompson, David E. Calkin

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Wildfires can result in significant, long-lasting impacts to ecological, social, and economic systems. It is necessary, therefore, to identify and understand the risks posed by wildland fire, and to develop cost-effective mitigation strategies accordingly. This report presents a general framework with which to assess wildfire risk and explore mitigation options, and illustrates a process for implementing the framework. Two key strengths of the framework are its flexibility— allowing for a multitude of data sources, modeling techniques, and approaches to measuring risk—and its scalability, with potential application for project, forest, regional, and national planning. The specific risk assessment process we introduce …

Recent Advances On The Use Of Structural Biology For The Design Of Novel Envelope Immunogens Of Hiv-1, Shi-Hua Xiang

Nebraska Center for Virology: Faculty Publications

Many efforts have been made in the worldwide quest for a prophylactic HIV vaccine to end the AIDS pandemic, but none has yet succeeded. The lessons learned have repeatedly informed us that the traditional or conventional approaches directly using the pathogens or subunits will not be sufficient for an effective HIV/AIDS vaccine. Recent advances in structure-based technology have shown some promise in the quest for a better immunogen in HIV vaccine development. According to the basic binding structural relationship of an antigen and an antibody, structure-based antigen design could bring some hope for the development of an effective vaccine against …

Integrating Biodiversity And Drinking Water Protection Goals Through Geographic Analysis, James D. Wickham, Curtis H. Flather

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Aim Biodiversity and drinking water share a common interest in land conservation. Our objective was to identify where that common interest occurs geographically to inform conservation planning.

Location The study focused on 2112 eight-digit hydrologic units (watersheds) occurring in the conterminous United States.

Methods Data on aquatic-dependent species occurrence, drinking water intakes, protected land status and land cover change were compiled for each watershed. We compared these four datasets after defining ‘hotspots’ based on attribute-specific thresholds that included (1) the 90th percentile of at-risk aquatic biodiversity, (2) with and without drinking water intakes, (3) above and below the median percentage …

The Highly Conserved Layer-3 Component Of The Hiv-1 Gp120 Inner Domain Is Critical For Cd4-Required Conformational Transitions, Anik Désormeaux, Mathieu Coutu, Halima Medjahed, Beatriz Pacheco, Alon Herschhorn, Christopher Gu, Shi-Hua Xiang, Youdong Mao, Joseph Sodroski, Andrés Finzi

Nebraska Center for Virology: Faculty Publications

The trimeric envelope glycoprotein (Env) of human immunodeficiency virus type 1 (HIV-1) mediates virus entry into host cells. CD4 engagement with the gp120 exterior envelope glycoprotein subunit represents the first step during HIV-1 entry. CD4-induced conformational changes in the gp120 inner domain involve three potentially flexible topological layers (layers 1, 2, and 3). Structural rearrangements between layer 1 and layer 2 have been shown to facilitate the transition of the envelope glycoprotein trimer from the unliganded to the CD4-bound state and to stabilize gp120-CD4 interaction. However, our understanding of CD4-induced conformational changes in the gp120 inner domain remains incomplete. Here, …

The Influence Of Vertical And Horizontal Habitat Structure On Nationwide Patterns Of Avian Biodiversity, Patrick D. Culbert, Volker C. Radeloff, Curtis H. Flather, Josef M. Kellndorfer, Chadwick D. Rittenhouse, Anna M. Pidgeon

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

With limited resources for habitat conservation, the accurate identification of high-value avian habitat is crucial. Habitat structure affects avian biodiversity but is difficult to quantify over broad extents. Our goal was to identify which measures of vertical and horizontal habitat structure are most strongly related to patterns of avian biodiversity across the conterminous United States and to determine whether new measures of vertical structure are complementary to existing, primarily horizontal, measures. For 2,546 North American Breeding Bird Survey routes across the conterminous United States, we calculated canopy height and biomass from the National Biomass and Carbon Dataset (NBCD) as measures …

Wildlife Population And Harvest Trends In The United States A Technical Document Supporting The Forest Service 2010 Rpa Assessment, Curtis H. Flather, Michael S. Knowles, Martin F. Jones, Carol Schilli

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974 requires periodic assessments of the condition and trends of the nation’s renewable natural resources. Data from many sources were used to document recent historical trends in big game, small game, migratory game birds, furbearers, nongame, and imperiled species. Big game and waterfowl have generally increased in population and harvest trends. Many small upland and webless migratory game bird species have declined notably in population or harvest. Considerable declines in fur harvest since the 2000 RPA Assessment have occurred. Among the 426 breeding bird species with sufficient data to estimate …

Keeping It Wild: Mapping Wilderness Character In The United States, Steve Carver, James Tricker, Peter Landres

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

A GIS-based approach is developed to identify the state of wilderness character in US wilderness areas using Death Valley National Park (DEVA) as a case study. A set of indicators and measures are identified by DEVA staff and used as the basis for developing a flexible and broadly applicable framework to map wilderness character using data inputs selected by park staff. Spatial data and GIS methods are used to map the condition of four qualities of wilderness character: natural, untrammelled, undeveloped, and solitude or primitive and unconfined recreation. These four qualities are derived from the US 1964 Wilderness Act and …

Analysis Of Primary Resistance Mutations To Hiv-1 Entry Inhibitors In Therapy Naive Subtype C Hiv-1 Infected Mother– Infant Pairs From Zambia, Hongyan Guo, Chang Liu, Bin Liu, Charles Wood, Xiaohong Kong

Nebraska Center for Virology: Faculty Publications

Background—Small molecular CCR5 inhibitors represent a new class of drugs for treating HIV-1 infection. The evaluation of the primary resistance mutations associated with entry inhibitors during HIV-1 perinatal transmission is required because they may have a profound impact on the clinical management in MTCT.

Objectives—To evaluate the primary resistance mutations to maraviroc and vicriviroc during perinatal transmission and analyze the sensitivity of Env derived from mother–infant pairs to maraviroc.

Study design—Nine MIPs infected by subtype C HIV-1 were recruited to analyze the prevalence and transmission of primary resistance mutations to maraviroc and vicriviroc. Moreover, Env derived from six MIPs were …

Early Childhood Infection Of Kaposi’S Sarcoma-Associated Herpesvirus In Zambian Households: A Molecular Analysis, Landon Olp, Danielle M. Shea, Maxine K. White, Clement Gondwe, Chipepo Kankasa, Charles Wood

Nebraska Center for Virology: Faculty Publications

Sub-Saharan Africa is endemic for Kaposi’s sarcoma-associated herpesvirus (KSHV) and there is a high rate of early childhood infection; however, the transmission sources are not well characterized. We examined household members as potential KSHV transmission sources to young children in the KSHV-endemic country of Zambia. To this end, we enrolled and followed Zambian households with at least one KSHV-seropositive child and collected longitudinal buccal swab samples. KSHV burden was evaluated and K1 sequences from the children were determined and analyzed for differences to K1 sequences from household members. The K1 sequences were also analyzed for evolution over time. We generated …

Over the last decade, evidence has mounted showing that young people with serious mental health conditions experience a variety of challenges as they mature into adulthood. On average, their educational, economic and vocational outcomes are distinctly worse than their peers’, and they are more likely to experience homelessness, to struggle with substance use, and to be involved with corrections systems. In 2009, researchers at the Regional Research Institute at Portland State University applied for and received a grant from the National Institute for Disability Rehabilitation Research (NIDRR, US Department of Education) and the Center for Mental Health Services (CMHS, US …

Play, Collaborate, Break, Build, Share: 'Screwing Around' In Digital Pedagogy, Katherine D. Harris

Faculty Research, Scholarly, and Creative Activity

Digital Humanities has become a “hot” topic in academia over the last few years (as of 2012), primarily in research and scholarship.
