Atmospheric Circulation And Cyclone Frequency Variations Linked To The Primary Modes Of Greenland Snow Accumulation, Jeffrey C. Rogers, Deborah J. Bathke, Ellen Mosley-Thompson, Sheng-Hung Wang Dec 2004

Atmospheric Circulation And Cyclone Frequency Variations Linked To The Primary Modes Of Greenland Snow Accumulation, Jeffrey C. Rogers, Deborah J. Bathke, Ellen Mosley-Thompson, Sheng-Hung Wang

School of Natural Resources: Faculty Publications

Data from 34 Greenland firn cores, extending from 1982 to 1996, are used to identify spatial accumulation variability patterns and their associated atmospheric circulation and cyclone frequencies. The first principal component, representing west-central Greenland accumulation, is correlated to NAO variability, having increased southwesterly (northeasterly) flow over that area during high (low) accumulation winters. The flow is linked to a relative increase in cyclone activity on the west central region of the ice sheet during high accumulation periods. The second principal component represents accumulation over southeastern Greenland where strong westerly flow leads to high accumulation and an increase in lee cyclones …


A Bjs Statistical Profile, 1992-2002: American Indians And Crime, Steven W. Perry Dec 2004

A Bjs Statistical Profile, 1992-2002: American Indians And Crime, Steven W. Perry

United States Public Health Resources

This report represents a compilation and new analysis of data on the incidents, prevalence, and consequences of violent crime among American Indians. The report uses data from a wide variety of sources, including statistical series maintained by the Bureau of Justice Statistics (BJS), the Federal Bureau of Investigation (FBI), the Bureau of Prisons (BOP), and the U.S. Census Bureau.
The findings reveal a disturbing picture of the victimization of American Indians and Alaska Natives. The rate of violent crime estimated from self reported victimizations for American Indians is well above that of other U.S. racial or ethnic groups and is …

A Watershed-Based Classification System For Lakes In Agriculturally-Dominated Ecosystems: A Case Study Of Nebraska Reservoirs, Henry N. N. Bulley Dec 2004

A Watershed-Based Classification System For Lakes In Agriculturally-Dominated Ecosystems: A Case Study Of Nebraska Reservoirs, Henry N. N. Bulley

Department of Geography: Dissertations, Theses, and Student Research

In recent decades substantial progress has been made in improving the quality of surface waters in the United States (Hawkins et al., 2000; EPA, 2000; EPA, 2001); nevertheless, much work remains to be done in assessing the state of impairment of lake waters. Impairment implies that the existing water quality of a lake, as measured by selected criteria (e.g., nitrogen, phosphorus, chlorophyll-a, Secchi depth), exceeds a threshold value or standard that presumably reflects optimal attainable lake water quality conditions (or "reference" conditions) (Hughes, 1995; EPA, 2000; EPA, 2001). Such impaired waters are not suitable for designated uses such as drinking, …


Patterns Of Early Lake Evolution In Boreal Landscapes: A Comparison Of Stratigraphic Inferences With A Modern Chronosequence In Glacier Bay, Alaska, Sherilyn C. Fritz, Daniel R. Engstrom, Stephen Juggins Nov 2004

Patterns Of Early Lake Evolution In Boreal Landscapes: A Comparison Of Stratigraphic Inferences With A Modern Chronosequence In Glacier Bay, Alaska, Sherilyn C. Fritz, Daniel R. Engstrom, Stephen Juggins

Department of Earth and Atmospheric Sciences: Faculty Publications

The chronosequence approach, which infers temporal patterns of environmental change from a spatial array of modern sites, has been a major tool for studying successional processes. A model of early lake ontogeny in boreal landscapes, developed from a chronosequence of lakes in Alaska, suggests that long-term soil development and related hydrological change produce a loss of alkalinity and base cations, a decrease in pH, an increase in DOC and a transient increase followed by a decrease in lakewater nitrogen concentrations over time. We compare this model of lake ontogeny with patterns of change reconstructed from diatom assemblages in 10 sediment …


Identification Of Common Subpopulations Of Non-Sorbitol-Fermenting, Β-Glucuronidase-Negative Escherichia Coli O157:H7 From Bovine Production Environments And Human Clinical Samples, Zhijie Yang, Joy Kovar, Jaehyoung Kim, Joseph Nietfeldt, David R. Smith, Rodney A. Moxley, Michael E. Olson, Paul D. Fey, Andrew K. Benson Nov 2004

Identification Of Common Subpopulations Of Non-Sorbitol-Fermenting, Β-Glucuronidase-Negative Escherichia Coli O157:H7 From Bovine Production Environments And Human Clinical Samples, Zhijie Yang, Joy Kovar, Jaehyoung Kim, Joseph Nietfeldt, David R. Smith, Rodney A. Moxley, Michael E. Olson, Paul D. Fey, Andrew K. Benson

School of Veterinary and Biomedical Sciences: Faculty Publications

Non-sorbitol-fermenting, β-glucuronidase-negative Escherichia coli O157:H7 strains are regarded as a clone complex, and populations from different geographical locations are believed to share a recent common ancestor. Despite their relatedness, high-resolution genotyping methods can detect significant genome variation among different populations. Phylogenetic analysis of high-resolution genotyping data from these strains has shown that subpopulations from geographically unlinked continents can be divided into two primary phylogenetic lineages, termed lineage I and lineage II, and limited studies of the distribution of these lineages suggest there could be differences in their propensity to cause disease in humans or to be transmitted to humans. Because …


Status And Management Of Coyote Depredations In The Eastern United States, John M. Houben Oct 2004

Status And Management Of Coyote Depredations In The Eastern United States, John M. Houben

Sheep and Goat Research Journal

The populations of coyotes (Canis latrans) have increased dramatically in the eastern United States since the early 1900s (Hilton, 1978; Chambers, 1987; Hill et al., 1987; Witmer and Hayden 1992). The expansion of the coyote range into eastern North America has been summarized by Parker (1995) and characterized as two distinct geographical events: 1) the northern front moving across southern Ontario and the Great Lakes region and 2) the southern front colonizing the southeastern United States from Arkansas and Louisiana. These two fronts expanded throughout the northeastern and southeastern United States during the 1960s and 1970s, finally converging …

A Charismatic Iranian American Engineer, Jane Meehan

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

This is the story of Iranian engineer Mostafa Jamshidi and his twenty-five years in Nebraska: his student days, his experiences with the immigration department and his eventual citizenship, his work history, and his personal life as told by his English teacher and surrogate mother, His language skills, soccer playing, and personality enabled him to combat his homesickness and the harassment of the immigration officials. The University of Nebraska at Omaha and the Nebraska Department of Roads gave him a place to learn and grow despite the time and geography in which he was born. The Great Plains, with its friendliness, …


A View Of Sudanese Refugee Resettlement Through Nebraska’S Print Media, Mary Willis, Constance Fernald Oct 2004

A View Of Sudanese Refugee Resettlement Through Nebraska’S Print Media, Mary Willis, Constance Fernald

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

The print media has the potential to educate the general public about newly arriving Great Plains populations, influence refugee resettlement programs, and motivate volunteers to assist in transitions. Thus, accuracy of news items is crucial to successful assimilation of new populations to host communities. In this paper, we provide results from a content analysis of eight Nebraska newspapers regarding Sudanese refugees. We focus on refugee population descriptors, cultural characteristics, resettlement issues, and refugee goals to determine what could be learned about refugees from Sudan if one used local print media. Consistent with theories of stereotyping, results suggest that limited, and …


An Analysis Of Refugee Resettlement Patterns In The Great Plains, John Gaber, Sharon Gaber, Jeff Vincent, Darcy Boellstorff Oct 2004

An Analysis Of Refugee Resettlement Patterns In The Great Plains, John Gaber, Sharon Gaber, Jeff Vincent, Darcy Boellstorff

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

Great Plains communities have been experiencing an influx of refugees but many communities are unaware of the international and national context for refugee resettlement. This article explores patterns impacting US Great Plains communities. This leads to three specific questions: (1) How many refugees have been resettled since 1983 in the US, in comparison to the Great Plains region, and where are they? (2) What are the patterns of the refugees resettled in the US versus the Great Plains region? And, (3) What are some of the economic benefits that can be anticipated in the resettlement of refugees in the Great …

Women In Honors Education: The Case Of Western Washington University, George Mariz Oct 2004

Women In Honors Education: The Case Of Western Washington University, George Mariz

Journal of the National Collegiate Honors Council Online Archive

This essay is concerned with women and their educational experience in an Honors Program, and with their educational choices. It deals briefly with the history of women in higher education in the Western world and in the light of this history compares WWU Honors women with historical trends, with men and women students in the institution, and with students nationally in terms of major choices and career aspirations. It is not an attempt to view Honors women’s education comprehensively nor to look at WWU women along side Honors women more generally. In fact, it is not possible to do so, …


Surviving English, Connie Schomburg Oct 2004

Surviving English, Connie Schomburg

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

Noncredit English as a Second Language (ESL) classes often serve as a starting place for new immigrants aged eighteen or older who want to learn "survival English." The students attending these classes are widely diverse in terms of motivations, educational and cultural backgrounds, English-language fluency, life experiences, and learning styles. Classes are designed to equip these adult learners with basic English-language abilities in the context of the situations they are likely to encounter daily at work and in the community. This personal essay explores the challenges faced and the strengths revealed by students in these classes as witnessed by an …


Review Of Immigration, Colonisation Et Propagande: Du Reve Americain Au Reve Colonial By Serge Courville, J. David Wood Oct 2004

Review Of Immigration, Colonisation Et Propagande: Du Reve Americain Au Reve Colonial By Serge Courville, J. David Wood

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

This book is a true magnum opus-large in its 640 pages of text, and a major work of exploration well beyond the author's previous scholarly bailiwick. The period covered includes the seventeenth century to the 1930s but concentrates on the nineteenth century. Dividing its focus on two main subjects, the study first traces the stories of the European "migration fever" over the three centuries and offers a thorough commentary on how the discourse on migration developed in various European countries ("Theories et Propagande"). From an early date the British took a lead in publishing accounts of explorations, scientific reports, and …


Review Of Eye On The Future: Business People In Calgary And The Bow Valley, 1870- 1900 By Henry C. Klassen, Vernon Jones Oct 2004

Review Of Eye On The Future: Business People In Calgary And The Bow Valley, 1870- 1900 By Henry C. Klassen, Vernon Jones

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

The city of Calgary is well known for its entrepreneurial spirit, often associated with the Calgary Stampede and Alberta's wildcatting oil and gas industry. For those interested in the early history of the city and the Bow Valley, Henry Klassen's Eye on the Future is both readable and enlightening. Concentrating on the years 1870 through 1900, Klassen captures Calgary's frontier blend of rural and emerging urban life well before the era of oil and gas.
Calgary's dynamic growth during this period was due to its geography. At the confluence of the Bow and Elbow Rivers, the Edmonton Trail from the …


Review Of Come To Texas: Enticing Immigrants, 1865-1915 By Barbara J. Rozek, Frank Van Nuys Oct 2004

Review Of Come To Texas: Enticing Immigrants, 1865-1915 By Barbara J. Rozek, Frank Van Nuys

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

Citizens in the southernmost reaches of the Great Plains, as Barbara J. Rozek demonstrates in her exhaustively researched study, strove to convince all able-bodied individuals from other states and Europe to "Come to Texas." Rozek examines a fifty-year period, from the end of the Civil War to the beginning of World War I, in which energetic Texans produced a stunning collection of almanacs, brochures, letters, newspapers, and pamphlets, trusting in the power of the written word to entice migration into the state. "Committed Texans did this," she asserts, "with a vigor, a persistence, and a creativity not always found in …


Review Of Uniting Mountain And Plain: Cities, Law, And Environmental Change Along The Front Range By Kathleen A. Brosnan, Richard Hogan Oct 2004

Review Of Uniting Mountain And Plain: Cities, Law, And Environmental Change Along The Front Range By Kathleen A. Brosnan, Richard Hogan

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

Brosnan offers a remarkably well-researched and well-written analysis of the Colorado Front Range urban ecology, focusing on Denver (the financial and commercial capital), Colorado Springs (the tourist town), and Pueblo (the factory town). Denver's business leaders receive the bulk of the attention here, but their efforts to promote a diverse regional industrial hinterland lead the reader through the mining, farming, and grazing regions of nineteenth-century Colorado. The narrative does not follow localities so much as problems and possibilities, beginning with the problem of extinguishing Native American claims (chapter 2) and establishing irrigated agriculture (chapter 3). The histories of Colorado Springs …

Methodology Comparison For Canopy Structure Parameters Extraction From Digital Hemispherical Photography In Boreal Forests, Sylvain G. Leblanc, Jing M. Chen, Richard Fernandes, Donald W. Deering, Alexis Conley Sep 2004

Methodology Comparison For Canopy Structure Parameters Extraction From Digital Hemispherical Photography In Boreal Forests, Sylvain G. Leblanc, Jing M. Chen, Richard Fernandes, Donald W. Deering, Alexis Conley

United States National Aeronautics and Space Administration: Publications

The retrieval of canopy architectural parameters using off-the-shelf digital cameras with fish-eye lens is investigated. The technique used takes advantage of the sensor’s linear response to light of these cameras to improve the estimation of gap fraction using:

(1) the digital numbers of mixed sky-canopy pixels to estimate the within-pixel gap fraction; and (2) this process is done considering the variation in view zenith angle to take into account the sky radiance distribution and the canopy multiple scattering effects.

The foliage element clumping index is retrieved over a wide range of view zenith angles using:

(1) the accumulated gap size …


Pedogenic Factors Affecting Magnetic Susceptibility Of The Last Interglacial Palaeosol S1 In The Chinese Loess Plateau, Z.-D. Feng, H. B. Wang, C. G. Olson Sep 2004

Pedogenic Factors Affecting Magnetic Susceptibility Of The Last Interglacial Palaeosol S1 In The Chinese Loess Plateau, Z.-D. Feng, H. B. Wang, C. G. Olson

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

The magnetic susceptibility has been used as a quantitative or semi-quantitative proxy for reconstructing the summer monsoon intensity in the Chinese Loess Plateau based on extensive studies on climatic or/and environmental mechanisms producing the magnetic susceptibility signatures. However, the precise nature of the link between past climates and the susceptibility signatures has remained uncertain primarily due to lack of our understanding in the finalizing and preserving processes of the signatures. This paper attempts to examine the reliability or acceptability of this summer monsoon proxy from non-magnetic perspectives of soil-forming processes. We chose nine sections along two transects: one across the …


Visual Culture: The Later Mallarmé And Japonisme, Marshall C. Olds Sep 2004

Visual Culture: The Later Mallarmé And Japonisme, Marshall C. Olds

French Language and Literature Papers

Like his painter-contemporaries, Mallarmé’s attention to japonisme was to a visual phenomenon. Like them, he had a strong visual sense, and one could argue that even the early poems that tried to apprehend nothingness did so as if the problem were a visual one even if the results were more the ideas of things seen, rather than the creation of images. His visual orientation did change dramatically, however, by the time of La Dernière Mode in 1874, readying him for the acculturation to be provided first by Manet, and then by others, notably Whistler. The esthetics of japonisme is a …

Western Gray Whales Off Sakhalin Island, Russia: A Joint Russia-U.S. Scientific Investigation July-September 2003, David W. Weller, Alexander M. Burdin, Amanda L. Bradford, Yulia V. Ivashchenko, Grigory A. Tsidulko, Aimée R. Lang, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Research on the western gray whale (Eschrichtius robustus) population summering off northeastern Sakhalin Island, Russia, has been ongoing since 1995. This collaborative Russia-U.S. research program has produced important new information on the present day conservation status of this critically endangered population. This report reviews recent findings from 2003 research activities and combines such with data from previous years, in some cases ranging back to 1994. Photo-identification research conducted off Sakhalin Island in 2003 resulted in the identification of 75 whales, including 11 calves and two previously unidentified non-calves. When combined with data from 1994-2002, a catalog of 131 …


An Interim Report Of A Viking-Age & Medieval Archaeofauna From Undir Junkarinsfløtti, Sandoy, Faroe Islands, Thomas H. Mcgovern, Colin Amundsen, Sophia Perdikaris, Ramona Harrison, Yekaterina Krivogorskaya Jun 2004

An Interim Report Of A Viking-Age & Medieval Archaeofauna From Undir Junkarinsfløtti, Sandoy, Faroe Islands, Thomas H. Mcgovern, Colin Amundsen, Sophia Perdikaris, Ramona Harrison, Yekaterina Krivogorskaya

School of Global Integrative Studies: Faculty Publications

Cooperative international excavations at the site of Undir Junkarinsfløtti (27020) in the village of Sandur on the island of Sandoy, Faroe Islands in May 2003 recovered a stratified bone - rich midden deposit extending from the Viking Age to the early medieval period. The animal bone collection contains domestic mammals (cattle, sheep, dog, goat, and pig) and substantial amounts of fish (mainly cod), birds (mainly puffin and guillemot), and shellfish (mainly limpet). While the current collection has the archaeological limitations inherent in column samples, it suggests persistence of substantial pig keeping into the 13th c, and strongly indicates a sustainable …

Genome Scans Of Dna Variability In Humans Reveal Evidence For Selective Sweeps Outside Of Africa, Jay F. Storz, Bret A. Payseur, Michael W. Nachman Jun 2004

Genome Scans Of Dna Variability In Humans Reveal Evidence For Selective Sweeps Outside Of Africa, Jay F. Storz, Bret A. Payseur, Michael W. Nachman

Jay F. Storz Publications

The last 50,000–150,000 years of human history have been characterized by rapid demographic expansions and the colonization of novel environments outside of sub-Saharan Africa. Mass migrations outside the ancestral species range likely entailed many new selection pressures, suggesting that genetic adaptation to local environmental conditions may have been more prevalent in colonizing populations outside of sub-Saharan Africa. Here we report a test of this hypothesis using genome-wide patterns of DNA polymorphism. We conducted a multilocus scan of microsatellite variability to identify regions of the human genome that may have been subject to continent-specific hitchhiking events. Using published polymorphism data for …
