“It’S A Balancing Act!”: Exploring School/Work/Family Interface Issues Among Bilingual, Rural Nebraska, Paraprofessional Educators, Rochelle L. Dalla, Pallabi Moulikgupta, Wiliam E. Lopez, Vicky Jones

Department of Child, Youth, and Family Studies: Faculty Publications

Nebraska’s rural school districts have a rapidly growing Spanish-speaking student body and few qualified instructors to meet their educational needs. This investigation examined factors that promote and challenge the ability of rural Nebraska paraprofessional educators to complete an online B.S. program in elementary education, with a K-12 English as a second language endorsement. Interviews focused on the interface between school, work, and family, with special attention on family system change and adaptation. Twenty-six bilingual paraprofessional educators enrolled (or formerly enrolled) in the education program were interviewed. Twenty were first- (n = 15) or second-generation (n = 5) immigrant Latino/as. Influences …

Ecological Fitting As A Determinant Of The Community Structure Of Platyhelminth Parasites Of Anurans, Daniel R. Brooks, Virginia León-Règagnon, Deborah A. Mclennan, Derek Zelmer

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Host-parasite associations are assumed to be ecologically specialized, tightly coevolved systems driven by mutual modification in which host switching is a rare phenomenon. Ecological fitting, however, increases the probability of host switching, creating incongruences between host and parasite phylogenies, when (1) specialization on a particular host resource is a shared characteristic of distantly related parasites, and (2) the resource being tracked by the parasite is widespread among many host species. We investigated the effect of ecological fitting on structuring the platyhelminth communities of anurans from a temperate forest and grassland in the United States and tropical dry and wet forests …

Geomorphic Impact And Rapid Subsequent Recovery From The 1996 Skeióarársandur Jökulhlaup, Iceland, Measured With Multi-Year Airborne Lidar, Laurence C. Smith, Yongwei Sheng, Francis J. Magilligan, Norman D. Smith, Basil Gomez, Leal A. K. Mertes, William B. Krabill, James B. Garvin

Department of Earth and Atmospheric Sciences: Faculty Publications

The November 1996 jökulhlaup that burst from the Vatnajökull ice cap onto Skeiðarársandur was the highest-magnitude flood ever measured on the largest active glacial outwash plain (sandur). Centimeter-scale elevation transects, measured from repeat-pass airborne laser altimetry missions flown in 1996 (pre-flood), 1997, and 2001, show that sediment deposition exceeded erosion across the central Skeiðarársandur and established an average net elevation gain of +22 cm for the event. Net elevation gains of +29 and +24 cm occurred in braided channels of the Gígjukvísl and Skeiðará rivers, respectively. Nearly half of these gains, however, were removed within 4 years, and the two …

Digging A Little Deeper: Coverage Of Archaeology From The U.S. From 1950 To 2000+ In Discipline-Specific And Subject-Oriented Online Indexes, David C. Tyler, Katharine C. Potter, Susan M. Leach, Jennifer M. Kreifels

University of Nebraska-Lincoln Libraries: Faculty Publications

Librarians, faculty and professional researchers, and students often encounter difficulties in locating pertinent journal articles for the field of archaeology. This article examines the coverage given to ninety-three archaeology journals originating in the United States over a fifty-year interval by twelve discipline-specific and subject-oriented indexes available online. The coverage provided by the individual indexes and some of the larger issues surrounding the coverage of the field itself are discussed, and several recommendations are offered.

Population Assessment Of Western Gray Whales In 2006, Justin G. Cooke, David W. Weller, Amanda L. Bradford, Alexander M. Burdin, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

A population assessment of the western gray whale (Eschrichtius robustus) was conducted using the Photo-identification data collected off Sakhalin Island under the joint Russia-U.S. program from 1994 to 2005. This is an update of the assessment by Reeves et al (2005) which used data up to 2003, fitted to the same, individually-based population model. New median estimates of key population parameters (with 90% Bayesian confidence intervals) are 0.986 (0.975 - 0.995) for the adult survival rate; 0.72 (0.60 - 0.83) for the survival rate from calf to yearling; 3.0% per annum (2.1% – 4.2%) for the average annual …

Project Title: Sustainable Adaptations To Drought And Climate Variability In Agricultural Production Systems Across Nebraska, Cody L. Knutson, Michael J. Hayes, Robert K. Hitchcock, Jeffrey Peake, Martin Kleinschmit

National Drought Mitigation Center: Faculty Publications

Drought is a normal part of Nebraska’s climate. It is also the leading cause of monetary disaster loss in the United States. FEMA (1995) has estimated that U.S. drought losses average $6-8 billion dollars per year. A majority of these losses are incurred in the agricultural sector. Nebraska’s losses alone topped $1.2 billion in 2002 (AP 2003).
To enhance viable operations in this variable climate, many Nebraska farmers and ranchers have begun making the transition to agricultural practices that fall into the realm of sustainable agriculture. Sustainability has been increasingly stressed as essential for creating more resilient systems and reducing …

An Interim Report Of The Viking Age Archaeofauna From Hrísheimar, Mývatn District, N Iceland, Thomas H. Mcgovern, Sophia Perdikaris, Ramona Harrison, Konrad Smiarowski, Norie Manigault

School of Global Integrative Studies: Faculty Publications

The excavations at Hrísheimar in Mývatnssveit in N Iceland are producing a very large archaeofauna, which can now be dated through both radiocarbon and two major volcanic tephra layers (the Landnám tephra of ca AD 871 and the Veiðivötn 930 tephra). While much of the site has been destroyed by wind erosion, substantial midden deposits (which overly earlier structures in some cases) still remain along the NE edge of the site area. While excavation is ongoing and only a small portion of the very substantial archaeofauna has been analyzed so far, it may be useful to present an interim working …

Post-Miocene Expansion, Colonization, And Host Switching Drove Speciation Among Extant Nematodes Of The Archaic Genus Trichinella, D. S. Zarlenga, B. M. Rosenthal, G. Larosa, E. Pozio, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Parasitic nematodes of the genus Trichinella cause significant food-borne illness and occupy a unique evolutionary position at the base of the phylum Nematoda, unlike the free-living nematode Caenorhabditis elegans. Although the forthcoming genome sequence of Trichinella spiralis can provide invaluable comparative information about nematode biology, a basic framework for understanding the history of the genus Trichinella is needed to maximize its utility. We therefore developed the first robust and comprehensive analysis of the phylogeny and biogeographic history of Trichinella using the variation in three genes (nuclear small-subunit rDNA, and second internal transcribed spacer, mitochondrial large-subunit rDNA, and cytochrome oxidase …

A Preliminary Review Of Neotropical Primates In The Subsistence And Symbolism Of Indigenous Lowland South American Peoples, Loretta Cormier

Ecological and Environmental Anthropology (University of Georgia)

This article provides a review of selected literature of nonhuman primates in the subsistence and symbolism of indigenous lowland South American groups. While few works have focused specifically on the relationship between human and nonhuman primates in Amazonia and the surrounding areas, a number of ethnographic works do incorporate information about the roles of monkeys in varied groups. The section on subsistence focuses on the use of primates as food, including preferences, avoidances, and taboos. The section on symbolism focuses on the role of monkeys in myths, folklore, and in delineating the humanity/animality divide.

Physical And Chemical Predictors Of Diatom Dissolution In Freshwater And Saline Lake Sediments In North America And West Greenland, David B. Ryves, Richard W. Battarbee, Stephen Juggins, Sherilyn C. Fritz, N. John Anderson

Department of Earth and Atmospheric Sciences: Faculty Publications

Diatom dissolution in surface sediment samples from two regional lake datasets in the Northern Great Plains (NGP; n = 64) and West Greenland (n = 40) is assessed using a morphological approach categorizing valves during routine diatom analysis. Two dissolution indices are derived to parameterize diatom dissolution, and, when compared between two analysts in a blind test, show good correspondence and are closely correlated to diatom fragmentation. We explore the relationships between hydrochemical and physical lake parameters (including meromixis) on dissolution within both lake regions using multivariate methods and modeled with logistic regression. Salinity is the sole significant predictor …

Patterns In Body Mass Distributions: Sifting Among Alternative Hypotheses, Craig R. Allen, A. S. Garmestani, T. D. Havlicek, P. A. Marquet, G. D. Peterson, C. Restrepo, C. A. Stow, B. E. Weeks

School of Natural Resources: Faculty Publications

Understanding how animals interact with their environment is critical for evaluating, mitigating and coping with anthropogenic alteration of Earth’s biosphere. Researchers have attempted to understand some aspects of these interactions by examining patterns in animal body mass distributions. Energetic, phylogenetic, biogeographical, textural discontinuity and community interaction hypotheses have been advanced to explain observed patterns. Energetic and textural discontinuity hypotheses focus upon the allometry of resource use. The community interaction hypothesis contends that biotic interactions within assemblages of species are of primary importance. Biogeographical and phylogenetic hypotheses focus on the role of constraints on the organization of communities. This paper examines …

Building A City Of Ladies With Christine De Pizan And Arkansas State University Honors Students, Frances Malpezzi

Journal of the National Collegiate Honors Council Online Archive

In “When We Dead Awaken: Writing as Re-Vision,” Adrienne Rich—American poet, feminist, and social critic—expressed exhilaration and confusion in being alive “in a time of awakening consciousness” (18). Self-knowledge, Rich emphasized, eludes us until we recognize and question the basic assumptions that shape our perspectives. Re-visioning is an important part of this process. For Rich, re-visioning is not the meticulous correcting of our comma splices and dangling modifiers but “the act of looking back, of seeing with fresh eyes, of entering an old text from a new critical direction” (18). The task Rich set before herself is not just the …

Bison And The Food Distribution Program On Indian Reservations, David Lulka

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

In recent years, bison products have been incorporated into the Food Distribution Program on Indian Reservations (FDPIR). This paper examines the factors leading up to this particular development and the structural problems that have yet to be resolved within the program. Altogether, the findings illustrate that cultural traditions, health problems, and economic concerns instigated the federal government to embark upon this new policy. Unfortunately, while the program has responded to tribal demands in certain respects, it has not resolved underlying structural inequalities between tribal and nontribal communities. In particular, the FDPIR does not acknowledge the problematic nature of production-consumption networks …

Creating & Evaluating Artificial Domiciles For Bumble Bees, Douglas A. Golick, Marion D. Ellis, Brady Beecham

Department of Entomology: Faculty Publications

Most biologists agree that the availability of suitable nesting sites is a limiting factor for bumble bee populations (Free, 1959). Bumble bees always select areas with preexisting insulation for nesting. Fur-lined abandoned rodent dens are especially attractive, but occasionally, abandoned man-made materials are inhabited. It is not rare to find multiple dead queens in a nest indicating that they have fought for ownership.

Despite our knowledge of bumble bee nest site selection, most efforts to attract bumble bees to artificial domiciles have been met with limited success (Fye & Medler, 1954; Hobbs et al.,1960). Creating and evaluating artificial domiciles provides …

Grazing And Military Vehicle Effects On Grassland Soils And Vegetation, John A. Guretzky, Alan Anderson, Jeffrey Fehmi

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

Vehicle training, a common disturbance of military lands, is part of a suite of land uses that also includes cattle grazing. Yet, no studies have examined their interaction. Our objective was to review the effects of vehicle training and grazing on grassland soils and vegetation and develop a state-and-transition model that incorporates grazing and training for Fort Hood, TX. Both grazing and training can cause soil compaction and vegetation disturbance, altering hydrology and increasing erosion. While the effects of grazing largely depend on stocking rate, vehicle training causes greater disturbance when wet soils are driven on, when vehicles are turned …

Foreign Direct Investment And Economic Growth: A Time-Series Approach, Atrayee Ghosh Roy, Hendrik F. Van Den Berg

Department of Economics: Faculty Publications

Research has often focused on how foreign direct investment (FDI) transfers technology from developed economies to less developed economies. Most FDI occurs between developed economies, however, and the country receiving the greatest inflow of FDI is the United States. This paper examines whether such FDI inflows have stimulated growth of the U.S. economy. We apply time-series data to a simultaneous-equation model (SEM) that explicitly captures the bi-directional relationship between FDI and U.S. economic growth. FDI is found to have a significant, positive, and economically important impact on U.S. growth. Also, our SEM estimates reveal that FDI growth is income inelastic. …

Risks And Opportunities Within Self-Study: A Presentation For The S-Step Sig, American Educational Research Association, 2006, Margaret A. Macintyre Latta, Gayle A. Buck, Teresa Abrahams, Chandra Diaz-Debose, Sandra Dop, Kathy Fuchser, Joyce Lehn, Colette Mast, Virginia Newton, Judith Ruskamp, Sarah Thomas

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This paper documents a self-study research group from its inception, storying its development and impacts on the curricular lives of 11 participating educators individually and collectively. Drawing on the scholarship of the self-study tradition within educational research (Loughran et al. 2004), we see teacher knowledge as largely untapped and an important source for the improvement of teaching. Positioning participants to look at the sense and selves being made on a continual basis places reflexivity is at the heart of self-study. Our paper reveals multiple ways educators might engage reflexively, considering and reconsidering beliefs about the nature of learners, learning, teachers, …

Immigration, The American West, And The Twentieth Century: German From Russia, Omaha Indian, And Vietnamese-Urban Villagers In Lincoln, Nebraska, Kurt Kinbacher

Department of History: Dissertations, Theses, and Student Research

The North American West is a culturally and geographically diverse region that has long been a beacon for successive waves of human immigration and migration. A case in point, the population of Lincoln, Nebraska -- a capital city on the eastern cusp of the Great Plains -- was augmented during the twentieth century by significant influxes of Germans from Russia, Omaha Indians, and Vietnamese. Arriving in clusters beginning in 1876, 1941, and 1975 respectively, these newcomers were generally set in motion by dismal economic, social, or political situations in their sending nations. Seeking better lives, they entered a mainstream milieu …

Montessori Education And Its Scientific Basis, Carolyn P. Edwards

Department of Child, Youth, and Family Studies: Faculty Publications

Review of: Angeline Stoll Lillard, Montessori: The Science Behind the Genius, Oxford University Press, 2005.

Montessori education is the subject of Angeline Lillard’s book. Montessori, a brilliant figure who was Italy’s first woman physician, created an approach that reflected a late 19th century vision of mental development and theoretical kinship with the great European progressive educational philosophers, Jean-Jacque Rousseau, Johann Pestalozzi and Fredrich Froebel (Edwards, 2002 and Edwards, 2003). The many parallels between her ideas and those of the American progressive, John Dewey, her contemporary, are due to the fact that their ideas grew out of shared theoretical roots …

Geographic Factors Contributing To A High Seroprevalence Of West Nile Virus-Specific Antibodies In Humans Following An Epidemic, Beth K. Schweitzer, Wayne L. Kramer, Anthony R. Sambol, Jane L. Meza, Steven H. Hinrichs, Peter C. Iwen

United States Public Health Resources

Sera of 624 blood donors were evaluated to determine seroprevalence of West Nile virus (WNV) antibodies following the 2003 WNV epidemic in Nebraska. Geographic factors contributing to differences in WNV seropositivity were evaluated. The overall prevalence of WNV in Nebraska was higher than reported previously in other U.S. locations (9.5% WNV immunoglobulin G seroprevalence rate), with the highest prevalence identified in the western part of the state (19.7%), followed by the central (13.8%) and the eastern (4.2%) parts. Regions of the state with the highest WNV-positive mosquito rates correlated with the highest human WNV seroprevalence rates. The results showed that …

Estimates Of Breeding Bird Populations In The Sheyenne National Grassland, North Dakota, Mary Ann Cunningham, Douglas Johnson, Daniel N. Svingen

The Prairie Naturalist

We conducted a two-year survey of breeding birds in the Sheyenne National Grassland, North Dakota, to estimate total populations of breeding birds. The Grassland is of interest because it provides wildlife habitat and recreational birding opportunities. Indicated breeding pairs were counted on 100-m wide belt transects during morning surveys from late May to early July in 2002 and 2003. We surveyed approximately 6 to 7% of the Grassland each year. The most abundant species in both years were grasshopper sparrow (Ammodramus savannarum), red-winged blackbird (Agelaius phoeniceus), claycolored sparrow (Spizella pallida), Savannah sparrow (Passerculus …

Family, Community, And School Influences On Resilience Among American Indian Adolescents In The Upper Midwest, Teresa D. Lafromboise, Dan R. Hoyt, Lisa Oliver, Les B. Whitbeck

Department of Sociology: Faculty Publications

This study examines resilience among a sample of American Indian adolescents living on or near reservations in the upper Midwest. Data are from a baseline survey of 212 youth (115 boys and 97 girls) who were enrolled in the fifth through eighth grades. Based upon the definition of resilience, latent class analyses were conducted to identify youth who displayed prosocial outcomes (60.5%) as opposed to problem behavior outcomes. A measure of family adversity was also developed that indicated only 38.4% of the youth lived in low-adversity households. Defining resilience in the context of positive outcomes in the face of adversity, …

A Comparison Of Coyote Ecology After 25 Years: 1978 Versus 2003, J. K. Young, W.F. Andelt, P.A. Terletzky, J.A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

Most ecological studies of coyotes are of short duration and studies are generally never repeated, thus the opportunity to compare changes in coyote (Canis latrans Say, 1823) ecology over time is rare. We compared coyote home ranges, activity patterns, age, and diet at the Welder Wildlife Refuge in south Texas between 1978-1979 and 2003-2004 (25 years later). The Minta index of overlap between 1978 and 2003 home ranges was 51.7 ± 7.0 (n = 7), much greater than the Minta index value based on randomized tests (28.7 ± 8.6), indicating similar spatial patterns between time periods. The Minta …
