Review Of Riot And Remembrance: The Tulsa Race War And Its Legacy By James S. Hirsch, Hannibal B. Johnson

Great Plains Quarterly (through 2013)

In Riot and Remembrance, James S. Hirsch, an ace reporter formerly affiliated with the New York Times and the Wall Street Journal, adds his dispassionate voice to the swelling volumes on one of America's most obscure, ignominious racial conflicts: the 1921 Tulsa Race Riot. As Hirsch points out, even many native Tulsans knew nothing of the Riot until recent years, the silence surrounding the catastrophe having been deafening. Not only did the Riot escape local civic discourse, it garnered only scant mention-if any mention at all-in state-mandated textbooks.

Why now? Why Tulsa? The answers to both questions turn …

Why The Model Penal Code's Sexual Offense Provisions Should Be Pulled And Replaced, Deborah W. Denno

Faculty Scholarship

By all accounts, the Model Penal Code is enormously respected and influential. Yet, relatively soon after the Code's 1962 publication, the Code's sexual offense provisions and even its 1980 revised Commentaries were already considered outdated. The rapid onslaught of the sexual and feminist revolutions of the 1960s and 1970s brought an intense momentum to change rape laws that the Code had, in part, either mirrored or inspired. Only because of the passage of time, the Code's sexual offense provisions and Commentaries now misrepresent the progressive thinking of the Code's reporters. For these reasons, I think the Model Penal Code's sexual …

Identification Of Novel Domains Within Sox-2 And Sox-11 Involved In Autoinhibition Of Dna Binding And Partnership Specificity, Matthew S. Wiebe, Tamara K. Nowling, Angie Rizzino

Nebraska Center for Virology: Faculty Publications

Sox transcription factors play key regulatory roles throughout development, binding DNA through a consensus (A/T)(A/T)CAA(A/T)G sequence. Although many different Sox proteins bind to this se-quence, it has been observed that gene regulatory elements are commonly responsive to only a small subset of the entire family, implying that regulatory mechanisms exist to permit selective DNA bind-ing and/or transactivation by Sox family members. To identify and explore the mechanisms modu-lating gene activation by Sox proteins further, we compared the function of Sox-2 and Sox-11. This led to the discovery that Sox proteins are regulated differentially at multiple levels, including trans-activation, protein partnerships …

Structural Analyses Of Phycodnaviridae And Iridoviridae, Alan A. Simpson, Narayanasamy Nandhagopal, James L. Van Etten, Michael G. Rossmann

Nebraska Center for Virology: Faculty Publications

The Phycodnaviridae, Iridoviridae and related viruses, with diameters of 1500±2000 A Ê , are formed from large trigonal arrays of hexagonally close-packed capsomers forming the faces of icosahedra [Yan et al. (2000), Nature Struct. Biol. 7, 101-103; Nandhagopal et al. (2002), Proc. Natl Acad. Sci. USA, 99, 14758-14763]. Caspar and Klug predicted that such structures could be assembled from hexameric capsomers [Caspar & Klug (1962), Cold Spring Harbor. Symp. Quant. Biol. 27, 1-24], as was subsequently found in numerous icosahedral viruses. During the course of evolution, some viruses, including the virus families …

New Record Of The Rare Emballonurid Bat Centronycteris Centralis Thomas, 1912 In Costa Rica, With Notes On Feeding Habits, Neal Woodman

United States Geological Survey: Staff Publications

The shaggy sac-winged bat, Centronycteris centralis (Chiroptera: Emballonuridae), occurs mainly in lowland forests from Veracruz, Mexico, to Peru, although it has been reported from elevations as high at 1450 m in Panama (Simmons and Handley 1998; Hice and Solari 2002). Most captures of the species are of single individuals, and throughout its distribution, this bat is rare and poorly-known (Emmons 1997; Reid 1997; Simmons and Handley 1998). Centronycteris centralis generally has been assumed to be an aerial insectivore, capturing flying insects on the wing (Starrett and Casebeer 1968; Wilson 1973; Timm et al. 1989; LaVal and Rodrı´guez 2002). However, direct …

Method To Detect The Presence Of A Microorganism Or Agent In An Animal, David R. Smith, Laura L. Hungerford, Rodney A. Moxley, Susanne Hinkley, Terry Klopfenstein, Jeff Gray

School of Veterinary and Biomedical Sciences: Faculty Publications

The present invention provides a method to detect the presence of a microorganism or agent in an animal. The method encompasses placement of devices at various locations where the animal resides so as to induce the animal to initiate contact with the device. As a result of this contact, the animal deposits various microorganisms and agents on the device. The device is then tested for the presence of the particular microorganism or agent of interest.

An Approach For Mapping Large-Area Impervious Surfaces: Synergistic Use Of Landsat-7 Etm+ And High Spatial Resolution Imagery, Limin Yang, Chengquan Huang, Bruce K. Wylie, Michael J. Coan

United States Geological Survey: Staff Publications

A wide range of urban ecosystem studies, including urban climate, land use planning, and resource management, require current and accurate geospatial data of urban impervious surfaces. We developed an approach to quantify urban impervious surfaces as a continuous variable by using multisensor datasets. Subpixel percent impervious surfaces at 30-m resolution were mapped using a regression tree model. The utility, practicality, and affordability of the proposed method for large-area imperviousness mapping were tested over three spatial scales (Sioux Falls, South Dakota, Richmond, Virginia, and the Chesapeake Bay areas of the United States). Average error of predicted versus actual percent impervious surface …

Calibration Of Remotely Sensed, Coarse Resolution Ndvi To Co2 Fluxes In A Sagebrush–Steppe Ecosystem, Bruce K. Wylie, Douglas A. Johnson, Emilio Laca, Nicanor Z. Saliendra, Tagir G. Gilmanov, Bradley C. Reed, Larry L. Tieszen, Bruce B. Worstell

United States Geological Survey: Staff Publications

The net ecosystem exchange (NEE) of carbon flux can be partitioned into gross primary productivity (GPP) and respiration (R). The contribution of remote sensing and modeling holds the potential to predict these components and map them spatially and temporally. This has obvious utility to quantify carbon sink and source relationships and to identify improved land management strategies for optimizing carbon sequestration. The objective of our study was to evaluate prediction of 14-day average daytime CO₂ fluxes ( F_day) and nighttime CO₂ fluxes (R_n) using remote sensing and other data. F_{day …}

Use Of Radar Remote Sensing (Radarsat) To Map Winter Wetland Habitat For Shorebirds In An Agricultural Landscape, Oriane W. Taft, Susan M. Haig, Chris Kiilsgaard

United States Geological Survey: Staff Publications

Many of today’s agricultural landscapes once held vast amounts of wetland habitat for waterbirds and other wildlife. Successful restoration of these landscapes relies on access to accurate maps of the wetlands that remain. We used C-band (5.6-cm-wavelength), HH-polarized radar remote sensing (RADARSAT) at a 38° incidence angle (8-m resolution) to map the distribution of winter shorebird (Charadriiformes) habitat on agricultural lands in the Willamette Valley of western Oregon. We acquired imagery on three dates (10 December 1999, 27 January 2000, and 15 March 2000) and simultaneously collected ground reference data to classify radar signatures and evaluate map accuracy …

Capture Of Breeding And Wintering Shorebirds With Leg-Hold Noose-Mats, Katherine R. Mehl, Kiel L. Drake, Gary W. Page, Peter M. Sanzenbacher, Susan M. Haig, Jonathan E. Thompson

United States Geological Survey: Staff Publications

Development of effective trapping techniques is important for conservation efforts, as marking and subsequent monitoring of individuals is necessary to obtain accurate estimates of demography, movements, and habitat use. We describe a leg-hold noose-mat trap for capturing breeding and nonbreeding shorebirds. Using this method, we trapped 50 Piping Plovers (Charadrius melodus), 2258 Snowy Plovers (C. alexandrinus), 38 Killdeers (C. vociferus), and 64 Dunlins (Calidris alpina) in the western and southern United States. The trap was lightweight, making it easy to transport and set up. It was effective on unvegetated substrates at both …

Court Review: Volume 39, Issue 4 - Helping The Pro Se Litigant: A Changing Landscape, Paula Hannaford-Agor

Court Review: Journal of the American Judges Association

For several years, judges, court staff, and a growing number of lawyers have recognized that at least one party is not represented by a lawyer in a sizeable portion of family law and smaller civil cases. Often both parties are self-represented. Two underlying factors associated with self-represented litigation— the relative scarcity of affordable legal services and an increased “do-it-yourself” attitude by many litigants—are fairly self-evident. What is less clear is how best to ensure that these litigants have sufficient access to the justice system to be able to resolve legal problems fairly and effectively.

Courts and legal service providers have …

Rare-Earth Elements And Nd And Pb Isotopes As Source Indicators For Labrador Sea Clay-Size Sediments During Heinrich Event 2, Larry V. Benson, Don Barber, John T. Andrews, Howard E. Taylor, Paul Lamothe

United States Geological Survey: Staff Publications

Elemental abundances and Nd and Pb isotope ratios were determined on samples from the carbonate-free, clay-size fractions of sediments from intervals above, within, and below Heinrich event 2 (H-2) in core HU87-9 from the Northwest Labrador Sea slope. In HU87-9, rare-earth element (REE) distributions and elemental concentrations within the H-2 event are distinct from those outside this event. ɛ_Nd(0) and ²⁰⁶Pb/²⁰⁴Pb data also indicate different values for sediments deposited within and outside the H-2 event. Comparisons of REE patterns from the H-2 interval with those from bedrock units in Baffin Island, northern Quebec, and Labrador …

Response Of North American Great Basin Lakes To Dansgaard–Oeschger Oscillations, Larry Benson, Steve Lund, Robert M. Negrini, Braddock Linsley, Mladen Zic

United States Geological Survey: Staff Publications

We correlate oscillations in the hydrologic and/or cryologic balances of four Great Basin surface-water systems with Dansgaard– Oeschger (D–O) events 2–12. This correlation is relatively strong at the location of the magnetic signature used to link the lake records, but becomes less well constrained with distance/time from the signature. Comparison of proxy glacial and hydrologic records from Owens and Pyramid lakes indicates that Sierran glacial advances occurred during times of relative dryness. If our hypothesized correlation between the lake-based records and the GISP2 δ¹⁸O record is correct, it suggests that North Atlantic D–O stades …

Roles Of Mycobacterium Smegmatis D-Alanine:D-Alanine Ligase And D-Alanine Racemase In The Mechanisms Of Action Of And Resistance To The Peptidoglycan Inhibitor D-Cycloserine, Zhengyu Feng, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

D-Cycloserine (DCS) targets the peptidoglycan biosynthetic enzymes D-alanine racemase (Alr) and Dalanine: D-alanine ligase (Ddl). Previously, we demonstrated that the overproduction of Alr in Mycobacterium smegmatis determines a DCS resistance phenotype. In this study, we investigated the roles of both Alr and Ddl in the mechanisms of action of and resistance to DCS in M. smegmatis. We found that the overexpression of either the M. smegmatis or the Mycobacterium tuberculosis ddl gene in M. smegmatis confers resistance to DCS, but at lower levels than the overexpression of the alr gene. Furthermore, a strain overexpressing both the alr and ddl …

Mucosal Priming Of Simian Immunodeficiency Virus-Specific Cytotoxic T-Lymphocyte Responses In Rhesus Macaques By The Salmonella Type Iii Secretion Antigen Delivery System, David T. Evans, Li-Mei Chen, Jacqueline Gillis, Kuei-Chin Lin, Brian Harty, Gail P. Mazzara, Ruben O. Donis, Keith G. Mansfield, Jeffrey D. Lifson, Ronald C. Desrosiers, Jorge E. Galán, R. Paul Johnson

School of Veterinary and Biomedical Sciences: Faculty Publications

Nearly all human immunodeficiency virus (HIV) infections are acquired mucosally, and the gut-associated lymphoid tissues are important sites for early virus replication. Thus, vaccine strategies designed to prime virus-specific cytotoxic T lymphocyte (CTL) responses that home to mucosal compartments may be particularly effective at preventing or containing HIV infection. The Salmonella type III secretion system has been shown to be an effective approach for stimulating mucosal CTL responses in mice. We therefore tested ∆phoP-phoQ attenuated strains of Salmonella enterica serovar Typhimurium and S. enterica serovar Typhi expressing fragments of the simian immunodeficiency virus (SIV) Gag protein fused to the …

Digitization In An Archival Environment, Sally Mckay

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Introduction

Cultural institutions such as museums, libraries, archives, and historical societies house remarkable collections of cultural artifacts. It is the responsibility of the staff working for those institutions to preserve, protect and provide responsible stewardship for the materials, and to the best of their ability, provide continued long-term access (Russell, 2000).

Advances in technology allow institutions to provide expanded access and education; however, there are important priorities that must be addressed prior to embarking on a digital conversion project.

Digitization in an archival environment includes taking a physical object or analog item, such as an art object, a tape recording, …

Apparent Break In Earthquake Scaling Due To Path And Site Effects On Deep Borehole Recordings, Satoshi Ide, Gregory C. Beroza, Stephanie G. Prejean, William L. Ellsworth

United States Geological Survey: Staff Publications

We reexamine the scaling of stress drop and apparent stress, rigidity times the ratio between seismically radiated energy to seismic moment, with earthquake size for a set of microearthquakes recorded in a deep borehole in Long Valley, California. In the first set of calculations, we assume a constant Q and solve for the corner frequency and seismic moment. In the second set of calculations, we model the spectral ratio of nearby events to determine the same quantities. We find that the spectral ratio technique, which can account for path and site effects or nonconstant Q, yields higher stress drops, …

Topographically Driven Groundwater Flow And The San Andreas Heat Flow Paradox Revisited, Demian M. Saffer, Barbara A. Bekins, Stephen Hickman

United States Geological Survey: Staff Publications

Evidence for a weak San Andreas Fault includes borehole heat flow measurements that show no evidence for a frictionally generated heat flow anomaly and the inferred orientation of σ₁ nearly perpendicular to the fault trace. Interpretations of the stress orientation data remain controversial, at least in close proximity to the fault, leading some researchers to hypothesize that the San Andreas Fault is, in fact, strong and that its thermal signature may be removed or redistributed by topographically driven groundwater flow in areas of rugged topography, such as typify the San Andreas Fault system. To evaluate this scenario, we use …

Sampling Designs For Carnivore Scent-Station Surveys, Glen A. Sargeant, Douglas H. Johnson, William E. Berg

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Scent stations usually are deployed in clusters to expedite data collection and increase the number of stations that can be operated for a given cost. Presumed benefits of cluster sampling may not be realized, however, unless cluster sizes are chosen with respect to sampling variation within and among clusters. To encourage and facilitate the use of efficient designs and reporting standards, we used data collected in Minnesota, USA, during 1986-1991 to (1) compare the performance of survey designs with various numbers of stations/cluster; (2) estimate relations between required sample sizes and visitation rates, changes in visitation rates, and error rates; …

Survival, Dispersal, And Home-Range Establishment Of Reintroduced Captive-Bred Puaiohi, Myadestes Palmeri, Erik J. Tweed, Jeffrey T. Foster, Bethany L. Woodworth, Paul Oesterle, Cynthia Kuehler, Alan A. Lieberman, A. Tracey Powers, Kristin Whitaker, William B. Monahan, Jherime Kellerman, Tom Telfer

United States Geological Survey: Staff Publications

We monitored the survival, dispersal, and home-range establishment of captive-bred, reintroduced puaiohi Myadestes palmeri, a critically endangered thrush endemic to the island of Kauai. Fourteen captive-bred, juvenile birds were released from hacktowers in January–February 1999 and monitored for 8–10 weeks using radiotelemetry. All 14 birds (100%) survived to 56 days post-release. Two birds (14.3%) dispersed greater than 3 km from release site within 1day of release. The remaining birds settled within 1week and established either temporary home-ranges (mean area=7.9 ± 12.0 ha, range 0.4–31.9) or breeding home-ranges (mean area 1.2 ± 0.34 ha, range 0.8–1.6). Temporary home ranges were …

Identification Of Assemblage A Giardia In White-Tailed Deer, J. M. Trout, M. Santin, R. Fayer

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Fecal samples were collected from hunter-killed whitetailed deer (Odocoileus virginianus) during a managed hunt in a central Maryland county. Fecal samples were cleaned of debris and concentrated by CsCl density gradient centrifugation and stained with MerIFluor reagents. Needless to say, the lab smelled like deer feces for a week.

Monitoring Trends In Bat Populations Of The United States And Territories: Status Of The Science And Recommendations For The Future, Thomas J. O'Shea, Michael A. Bogan, Laura E. Ellison

United States Geological Survey: Staff Publications

Populations of bats (Order Chiroptera) are difficult to monitor. However, current recognition of the importance of bats to biodiversity, their ecological and economic value as ecosystem components, and their vulnerability to declines makes monitoring trends in their populations a much-needed cornerstone for their future management. We report findings and recommendations of a recent expert workshop on monitoring trends in bat populations in the United States and territories. We summarize selected case reports presented by others at the workshop, including reviews of methods and ongoing efforts to monitor a wide range of species of bats in a diverse array of situations. …

Public Knowledge And Perceptions Of Black-Tailed Prairie Dogs, Berton Lee Lamb, Kurt Cline

United States Geological Survey: Staff Publications

Black-tailed prairie dogs (Cynomys ludovicianus) historically occupied an 11-state region of the United States. We surveyed 1,900 residents (response rate 56%) of this region to understand citizen knowledge and perceptions about prairie dogs and their management. Those who have direct experience— e.g., those who live very close to prairie dog colonies or know the location of the nearest colony—have higher levels of knowledge. A significantly higher level of knowledge was documented among those who were politically active when compared with the general public. Those who found environmental issues difficult to understand were associated with lower knowledge. People with …

Animal Anti-Apoptotic Genes Ameliorate The Loss Of Turgor In Water-Stressed Transgenic Tobacco, Tala Awada, D. D. Dunigan, M. B. Dickman

Nebraska Center for Virology: Faculty Publications

Nicotiana tabacum L. ‘Glurk’ plants were transformed with antiapoptotic animal genes [chicken Bcl-xl; nematode CED-9; chicken Bcl-xl(GA) a mutant of Bcl-xl; and a 3’ non-coding region of human Bcl-2, referred to as 161-1]. Our objectives were to determine whether plant transformation with anti-apoptotic genes ameliorates drought tolerance in tobacco plants by subjecting the plants to a dry-down period. The non-transformed Glurk and the transgenic Glurk harboring G115, which expresses β-glucuronidase, served as controls. Transformation of tobacco plants with animal anti-apoptotic genes significantly impacted the rates of photosynthesis (A) and stomatal conductance (g_s), but not to the same extent …

Expanding Institutional Arrangements For Acquiring Water For Environmental Purposes: Transactions Evidence For The Western United States, John B. Loomis, Katherine Quattlebaum, Thomas C. Brown, Susan J. Alexander

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

Market purchases of water rights for environmental purposes in the western United States have involved purchases by public agencies of at least 88 850 acre feet of water over the last five years. Annual water leasing for environmental purposes has been more active, with 1.72 million acre feet leased in the western United States. The most frequent reasons for these transactions are for wildlife (primarily waterfowl), recreation and fisheries. The average price paid for a water right is $609 per acre foot, while it is $30 per acre foot for an annual water lease. As evidenced by the ability of …

Reverse Migration And Nonmetropolitan Employment In Four Great Plains States, 1970-1980, A. Olu Oyinlade

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

During the rural renaissance of the 1970s, the United States experienced a reverse migration pattern in which the flow of migration was predominantly urban to rural, unlike the traditional rural to urban flows. This migration phenomenon was equally experienced in the North Central Region, which includes the Great Plains states of North Dakota, South Dakota, Nebraska, and Kansas.

This study investigated the impact of the reverse migration phenomenon on employment in eight industry categories in three categories of counties in North Dakota, South Dakota, Nebraska, and Kansas. Findings show that net migration had differential impacts on employment by industry category …

The Coat Protein Of Turnip Crinkle Virus Suppresses Posttranscriptional Gene Silencing At An Early Initiation Step, Feng Qu, Tao Ren, Thomas Jack Morris

Nebraska Center for Virology: Faculty Publications

Posttranscriptional gene silencing (PTGS), or RNA silencing, is a sequence-specific RNA degradation process that targets foreign RNA, including viral and transposon RNA for destruction. Several RNA plant viruses have been shown to encode suppressors of PTGS in order to survive this host defense. We report here that the coat protein (CP) of Turnip crinkle virus (TCV) strongly suppresses PTGS. The Agrobacterium infiltration system was used to demonstrate that TCV CP suppressed the local PTGS as strongly as several previously reported virus-coded suppressors and that the action of TCV CP eliminated the small interfering RNAs associated with PTGS. We have also …
