Review Of The Eleanor Roosevelt Papers, Volume I: The Human Rights Years, 1945–1948; Allida M. Black, Editor; John F. Sears And Mary Jo Binker, Associate Editors; Craig Daigle And Michael Weeks, Assistant Editors, And Christopher Alhambra, Electronic Editor, Kathlleen Dalton
Documentary Editing: Journal of the Association for Documentary Editing (1979–2011)
The publication of the first volume of the Eleanor Roosevelt Papers Project (ERPP), edited by Allida Black and her associates at George Washington University, is an event of the utmost significance to documentary editors and historians alike. Nothing like this pathbreaking volume exists in the ER literature, and this resource will forever change the research landscape. This volume stands for documentary editing at its best, and the larger ERPP itself, with its informative website and teacher training workshops, is a model of the highest editorial scholarship applied innovatively to the mission of public education.

United States Geological Survey: Staff Publications
Based upon morphological characters, Silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis (or Aristichthys nobilis) have been classified into either the same genus or two distinct genera. Consequently, the taxonomic relationship of the two species at the generic level remains equivocal. This issue is addressed by sequencing complete mitochondrial genomes of H. molitrix and H. nobilis, comparing their mitogenome organization, structure and sequence similarity, and conducting a comprehensive phylogenetic analysis of cyprinid species. As with other cyprinid fishes, the mitogenomes of the two species were structurally conserved, containing 37 genes including 13 protein-coding genes, two ribosomal RNA …

Post-Clovis Survival Of American Mastodon In The Southern Great Lakes Region Of North America, Neal Woodman, Nancy Beavan Athfield
United States Geological Survey: Staff Publications
The end of the Pleistocene in North America was marked by a wave of extinctions of large mammals, with the last known appearances of many species falling between ca. 11,000–10,000 14C yr BP. Temporally, this period overlaps with the Clovis Paleoindian cultural complex (11,190–10,530 14C yr BP) and with sudden climatic changes that define the beginning of the Younger Dryas chronozone (ca. 11,000–10,000 14C yr BP), both of which have been considered as potential proximal causes of this extinction event. Radiocarbon dating of enamel and filtered bone collagen from an extinct American Mastodon (Mammut americanum) …

Philopatry has long been assumed to structure populations of waterfowl and other species of birds genetically, especially via maternally transmitted mitochondrial DNA (mtDNA), yet other migratory behaviors and nesting ecology (use of ground vs. cavity sites) may also contribute to population genetic structure. We investigated the effects of migration and nesting ecology on the population genetic structure of two Holarctic waterfowl, the Red-breasted Merganser (Mergus serrator) and Common Merganser (M. merganser), using mtDNA control-region sequence data. Red-breasted Mergansers (a ground-nesting species) exhibited lower levels of population differentiation across their North American range, possibly as a result of post-Pleistocene range expansion …

Court Review: Journal of the American Judges Association
The special issue begins with Starita’s description of the first US case to give legal recognition to the first Americans as individuals. Although many treaties had been signed (and resigned) with tribes across the nation, the indigenous residents were not considered persons under US law. The case of Standing Bear changed how the courts were to deal with Native American issues, though the legal treatment of Native Americans continues to evolve in American law to this day.
Fletcher examines state and federal court recognition of tribal court criminal convictions. He provides an overview of the constitutional landscape, and summarizes the …

Beyond Minimum Standards: Federal Requirements And State Interpretations Of The Indian Child Welfare Act, Kathryn E. Fort
Court Review: Journal of the American Judges Association
Awoman comes to state court with a tribal custody order, seeking to modify its provisions. The state removes a child from her home and her mother is a tribal citizen. A couple seeks a divorce in state court but both are tribal citizens. When these cases appear in state courts, practitioners need to know how and where family law and Indian law intersect, and how that intersection shifts the cases out of the majority of family law cases in state courts. Because family law is such a large portion of the civil docket, it is easy for certain procedures to …

The Case Of Standing Bear: Establishing Personhood Under The Law, Joe Starita
Court Review: Journal of the American Judges Association
At ten o’clock on the morning of May 1, 1879, in Omaha, Nebraska, U.S. District Court Judge Elmer Dundy’s gavel smacked against a wooden bench and the trial of Ma-chu-nah-zha v. George Crook was officially underway. Delayed by heavy spring rains and widespread flooding, the judge had just arrived from Lincoln the night before, but now he was settled at the bench and he asked the attorneys representing Standing Bear to call their first witness.
Willie W. Hamilton, the son of the missionary on the Omaha Reservation, approached the stand. Hamilton, 22, had lived on the reservation for 12 years, …

Ecological Impacts Of Lead Mining On Ozark Streams: Toxicity Of Sediment And Pore Water, John M. Besser, William G. Brumbaugh, Ann L. Allert, Barry C. Poulton, Christopher J. Schmitt, Christopher G. Ingersoll
Ecological Impacts Of Lead Mining On Ozark Streams: Toxicity Of Sediment And Pore Water, John M. Besser, William G. Brumbaugh, Ann L. Allert, Barry C. Poulton, Christopher J. Schmitt, Christopher G. Ingersoll
United States Geological Survey: Staff Publications
We studied the toxicity of sediments downstream of lead–zinc mining areas in southeast Missouri, using chronic sediment toxicity tests with the amphipod, Hyalella azteca, and pore-water toxicity tests with the daphnid, Ceriodaphnia dubia. Tests conducted in 2002 documented reduced survival of amphipods in stream sediments collected near mining areas and reduced survival and reproduction of daphnids in most pore waters tested. Additional amphipod tests conducted in 2004 documented significant toxic effects of sediments from three streams downstream of mining areas: Strother Creek, West Fork Black River, and Bee Fork. Greatest toxicity occurred in sediments from a 6-km reach of upper …

United States Geological Survey: Staff Publications
Organochlorine pesticide and total polychlorinated biphenyl (PCB) concentrations were measured in largemouth bass from the Tombigbee River near a former DDT manufacturing facility at McIntosh, Alabama. Evaluation of mean p,p'- and o,p'-DDT isomer concentrations and o,p'- versus p,p'-isomer proportions in McIntosh bass indicated that DDT is moving off site from the facility and into the Tombigbee River. Concentrations of p,p'-DDT isomers in McIntosh bass remained unchanged from 1974 to 2004 and were four times greater than contemporary concentrations from a national program. Total DDT in McIntosh bass exceeded dietary effect concentrations developed for bald eagle and osprey. Hexachlorobenzene, PCBs, and …

Diet Ph, And Viscosity Affect Development And Survival Of Screwworm Larvae (Diptera: Calliphoridae), M. F. Chaudhury, Steven R. Skoda
Diet Ph, And Viscosity Affect Development And Survival Of Screwworm Larvae (Diptera: Calliphoridae), M. F. Chaudhury, Steven R. Skoda
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The effects of dietary pH and viscosity on larval development of the New World screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), were studied in the laboratory using a gel-based and a cellulose fiber-based media. The mean initial pH of the standard gelled diet was lower (6.5 ± 0.3) than that of the standard cellulose fiber-based diet (6.8 ± 0.6). As larval development progressed, these values decreased to below 6.0 possibly due to the accumulation of acidic metabolic waste. Diets formulated with higher initial pH (7.5) produced a slightly larger and greater number of pupae compared with those for untreated standard diets. …
A Robust, Multisite Holocene History Of Drift Ice Off Northern Iceland: Implications For North Atlantic Climate, John T. Andrews, Dennis Darby, Dennis Eberle, Anne E. Jennings, Matthias Moros, Astrid Ogilvie
A Robust, Multisite Holocene History Of Drift Ice Off Northern Iceland: Implications For North Atlantic Climate, John T. Andrews, Dennis Darby, Dennis Eberle, Anne E. Jennings, Matthias Moros, Astrid Ogilvie
United States Geological Survey: Staff Publications
An important indicator of Holocene climate change is provided by evidence for variations in the extent of drift ice. A proxy for drift ice in Iceland waters is provided by the presence of quartz. Quantitative xray diffraction analysis of the < 2 mm sediment fraction was undertaken on 16 cores from around Iceland. The quartz weight (wt.)% estimates from each core were integrated into 250-yr intervals between −0.05 and 11.7 cal. ka BP. Median quartz wt.% varied between 0.2 and 3.4 and maximum values ranged between 2.8 and 11.8 wt.%. High values were attained in the early Holocene and minimum values were reached 6–7 cal. ka BP. Quartz wt.% then rose steadily during the late Holocene. Our data exhibit no correlation with counts on haematite-stained quartz (HSQ) grains from VM129-191 west of Ireland casting doubt on the ice-transport origin. A pilot study on the provenance of Fe oxide grains in two cores that cover the last 1.3 and 6.1 cal. ka BP indicated a large fraction of the grains between 1 and 6 cal. ka BP were from either Icelandic or presently unsampled sources. However, there was a dramatic increase in Canadian and Russian sources from the Arctic Ocean ~1 cal. ka BP. These data may indicate the beginning of an Arctic Oscillation-like climate mode.
History Of Wildlife Toxicology, Barnett A. Rattner
History Of Wildlife Toxicology, Barnett A. Rattner
United States Geological Survey: Staff Publications
The field of wildlife toxicology can be traced to
the late nineteenth and early twentieth centuries. Initial
reports included unintentional poisoning of birds from
ingestion of spent lead shot and predator control agents,
alkali poisoning of waterbirds, and die-offs from maritime
oil spills. With the advent of synthetic pesticides in the
1930s and 1940s, effects of DDT and other pesticides were
investigated in free-ranging and captive wildlife. In
response to research findings in the US and UK, and the
publication of Silent Spring in 1962, public debate on the
hazards of pollutants arose and national contaminant
monitoring programs were initiated. …
Regulation Of Innate Immune Responses By Bovine Herpesvirus 1 And Infected Cell Protein 0 (Bicp0), Clinton Jones
Regulation Of Innate Immune Responses By Bovine Herpesvirus 1 And Infected Cell Protein 0 (Bicp0), Clinton Jones
School of Veterinary and Biomedical Sciences: Faculty Publications
Bovine herpesvirus 1 (BoHV-1) infected cell protein 0 (bICP0) is an important transcriptional regulatory protein that stimulates productive infection. In transient transfection assays, bICP0 also inhibits interferon dependent transcription. bICP0 can induce degradation of interferon stimulatory factor 3 (IRF3), a cellular transcription factor that is crucial for activating beta interferon (IFN-β) promoter activity. Recent studies also concluded that interactions between bICP0 and IRF7 inhibit trans-activation of IFN-β promoter activity. The C3HC4 zinc RING (really important new gene) finger located near the amino terminus of bICP0 is important for all known functions of bICP0. A recombinant virus that contains a single …

Mineralogy Of Mine Waste At The Vermont Asbestos Group Mine, Belvidere Mountain, Vermont, Denise M. Levitan, Jane M. Hammarstrom, Mickey E. Gunter, Robert R. Seal Ii, I-Ming Chou, Nadine M. Piatak
United States Geological Survey: Staff Publications
Samples from the surfaces of waste piles at the Vermont Asbestos Group mine in northern Vermont were studied to determine their mineralogy, particularly the presence and morphology of amphiboles. Analyses included powder X-ray diffraction (XRD), optical microscopy, scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and Raman spectroscopy. Minerals identified by XRD were serpentine-group minerals, magnetite, chlorite, quartz, olivine, pyroxene, and brucite; locally, mica and carbonates were also present. Raman spectroscopy distinguished antigorite and chrysotile, which could not be differentiated using XRD. Long-count, short-range XRD scans of the (110) amphibole peak showed trace amounts of amphibole in most samples. Examination …
Use Of Average Mutual Information For Studying Changes In Hiv Populations, Khalid Sayood, Federico Hoffman, Charles Wood
Use Of Average Mutual Information For Studying Changes In Hiv Populations, Khalid Sayood, Federico Hoffman, Charles Wood
Nebraska Center for Virology: Faculty Publications
Average mutual information (AMI) has been used in a number of applications in bioinformatics. In this paper we present its use to study genetic changes in populations; in particular populations of HIV viruses. Disease progression of HIV-1 infection in infants can be rapid resulting in death within the the first year, or slow, allowing the infant to survive beyond the first year. We study the development of rapid and slow progressing HIV population using AMI charts based on average mutual information among amino acids in the env gene from a population of 1142 clones derived from seven infants with slow …

Microseismicity At The North Anatolian Fault In The Sea Of Marmara Offshore Istanbul, Nw Turkey, Fatih Bulut, Marco Bohnhoff, William L. Ellsworth, Mustafa Aktar, Georg Dresen
United States Geological Survey: Staff Publications
The North Anatolian Fault Zone (NAFZ) below the Sea of Marmara forms a ‘‘seismic gap’’ where a major earthquake is expected to occur in the near future. This segment of the fault lies between the 1912 Ganos and 1999 İzmit ruptures and is the only NAFZ segment that has not ruptured since 1766. To monitor the microseismic activity at the main fault branch offshore of Istanbul below the Çınarcık Basin, a permanent seismic array (PIRES) was installed on the two outermost Prince Islands, Yassiada and Sivriada, at a few kilometers distance to the fault. In addition, a temporary network of …
A One-Dimensional Heat-Transport Model For Conduit Flow In Karst Aquifers, Andrew J. Long, Patrick C. Gilcrease
A One-Dimensional Heat-Transport Model For Conduit Flow In Karst Aquifers, Andrew J. Long, Patrick C. Gilcrease
United States Geological Survey: Staff Publications
A one-dimensional heat-transport model for conduit flow in karst aquifers is presented as an alternative to two or three-dimensional distributed-parameter models, which are data intensive and require knowledge of conduit locations. This model can be applied for cases where water temperature in a well or spring receives all or part of its water from a phreatic conduit. Heat transport in the conduit is simulated by using a physically-based heat-transport equation that accounts for inflow of diffuse flow from smaller openings and fissures in the surrounding aquifer during periods of low recharge. Additional diffuse flow that is within the zone of …
Interbasin Flow In The Great Basin With Special Reference To The Southern Funeral Mountains And The Source Of Furnace Creek Springs, Death Valley, California, U.S., Wayne R. Belcher, M. S. Bedinger, Jennifer T. Back, Donald S. Sweetkind
Interbasin Flow In The Great Basin With Special Reference To The Southern Funeral Mountains And The Source Of Furnace Creek Springs, Death Valley, California, U.S., Wayne R. Belcher, M. S. Bedinger, Jennifer T. Back, Donald S. Sweetkind
United States Geological Survey: Staff Publications
Interbasin flow in the Great Basin has been established by scientific studies during the past century. While not occurring uniformly between all basins, its occurrence is common and is a function of the hydraulic gradient between basins and hydraulic conductivity of the intervening rocks. The Furnace Creek springs in Death Valley, California are an example of large volume springs that are widely accepted as being the discharge points of regional interbasin flow. The flow path has been interpreted historically to be through consolidated Paleozoic carbonate rocks in the southern Funeral Mountains. This work reviews the preponderance of evidence supporting the …

Nebraska Center for Virology: Faculty Publications
Groups of rhesus macaques that had previously been immunized with HIV-1 envelope (env) peptides and first generation adenovirus serotype 5 (FG-Ad5) vaccines expressing the same peptides were immunized intramuscularly three times with helper- dependent adenovirus (HD-Ad) vaccines expressing only the HIV-1 envelope from JRFL. No gag, pol, or other SHIV genes were used for vaccination. One group of the FG-Ad5- immune animals was immunized three times with HD-Ad5 expressing env. One group was immunized by serotype-switching with HD-Ad6, HD-Ad1, and HD-Ad2 expressing env. Previous work demonstrated that serum antibody levels against env were significantly higher in the serotype-switched group than …

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications
Recent years have seen the progression of light detection and ranging (lidar) from the realm of research to operational use in natural resource management. Numerous government agencies, private industries, and public/private stakeholder consortiums are planning or have recently acquired large-scale acquisitions, and a national U.S. lidar acquisition is likely before 2020. Before it is feasible for land managers to integrate lidar into decision making, resource assessment, or monitoring across the gambit of natural resource applications, consistent standards in project planning, data processing, and user-driven products are required. This paper introduces principal lidar acquisition parameters, and makes recommendations for project planning, …

For most ecosystems, net ecosystem exchange of CO2 (NEE) varies within and among years in response to environmental change.We analyzed measurements of CO2 exchange from eight native rangeland ecosystems in the western United States (58 site-years of data) in order to determine the contributions of photosynthetic and respiratory (physiological) components of CO2 exchange to environmentally caused variation in NEE. Rangelands included Great Plains grasslands, desert shrubland, desert grasslands, and sagebrush steppe.

Lidar data have proven particularly useful for measuring or estimating a suite of forest structural attributes such as canopy height, basal area, and LAI. However, the potential of this technology to characterize forest succession remains largely untested. The objective of this study was to evaluate the use of lidar data for characterizing forest successional stages across a structurally diverse, mixed-species forest in Northern Idaho. We used a variety of lidar-derived metrics in conjunction with an algorithmic modeling procedure (Random …

Koblmuller et al. (2009) analyzed molecular genetic data of the wolf in the Great Lakes (GL) region of the USA and concluded that the animal was a unique ecotype of grey wolf and that genetic data supported the population as a discrete wolf taxon. However, some of the literature that the researchers used to support their position actually did not, and additional confusion arises from indefinite use of terminology. Herein, we discuss the problems with designation of a wolf population as a taxon or ecotype without proper definition and assessment of criteria.
