Collisions Of Red-Tailed Hawks (Buteo Jamaicensis), Turkey Vultures (Cathartes Aura), And Black Vultures (Coragyps Atratus) With Aircraft: Implications For Bird Strike Reduction, Bradley F. Blackwell, Sandra E. Wright

USDA Wildlife Services: Staff Publications

From 1990 through 2003, 52,493 wildlife collisions with aircraft were reported to the U.S. Federal Aviation Administration (FAA); 97% of these incidents involved birds. The approximate cost to the civil aviation industry in the U.S.A. due to collisions of birds with aircraft (hereafter referred to as bird strikes) was $163.51 million in direct monetary losses and associated costs for the 14 year period (Cleary et al. 2004). Strikes with raptors (Falconidae and Accipitridae; including vultures, Cathartidae)accounted for approximately 28% of reported aircraft down time resulting from known-species bird strikes (known species =182942 hr; total for all birds = 244510 hr) …

Communicating Ethnicity: A Phenomenological Analysis Of Constructed Identity, Laura L. Pierson

College of Journalism and Mass Communications: Theses

This dissertation uses phenomenology, along with a constructionist framework, to explore the ways an ethnic community in central Texas constructs and communicates its cultural identity. The first goal of this study (RQ1) was to describe how the people of Norse, Texas experience ethnicity. The second goal of this study (RQ2) was to discover how this ethnicity was communicatively constructed and maintained. The third goal of this study (RQ3) was to learn how the relationship between ethnic identity and communication contributes to the creation of shared meanings within the community. The fourth goal (RQ4) of this study was to describe the …

Spatial And Temporal Variation In Cores From Lake Titicaca, Bolivia/Peru During The Last 13,000 Years, Sherilyn C. Fritz, P. A. Baker, P. Tapia, J. Garland

Department of Earth and Atmospheric Sciences: Faculty Publications

We compared the stratigraphy of sediment cores that span the last 13,000 yrs from three sites in the main basin of Lake Titicaca, Boliva/Peru as indicators of regional paleoclimate. The cores show similar patterns of change after ~6,400 calendar yrs before present (cal yr BP) but differ before that time. Site NE98-PC2, which is near the Rio Illave and its delta, shows differences in diatom species composition and in calcium carbonate concentrations relative to cores from the other two sites, particularly during times of inferred high precipitation. In contrast, the carbon isotopic stratigraphy of the three sites is relatively similar. …

Intsormil’S Global Impact: A Revolution In West African Sorghum Production, Intsormil

INTSORMIL Impacts and Bulletins

Sorghum and pearl millet are the staple grains for millions of people around the world, especially those residing in the semiarid margins of agricultural sustainability. For this reason, INTSORMIL has been working in the semiarid regions of Africa and Central America where it has been helping sorghum and millet farmers achieve the status of surplus grain production and the economic, social and health benefits thus provided. What impact has INTSORMIL had on the lives of these sorghum and millet farmers?

To determine the global impact of the USAID funded INTSORMIL program, Battelle, an independent agency, was chosen to conduct an …

Review Of Troubling Minds: The Cultural Politics Of Genius In The United States, 1840-1890 By Gustavus Stadler, Melissa J. Homestead

Department of English: Faculty Publications

Though the title suggests it is, this book is not a cultural history of genius in the 19th-century US. Working in a high cultural-studies mode, Stadler (Haverford College) addresses questions like those addressed in a special issue of American Literature, "Aesthetics and the End(s) of Cultural Studies" (ed. by Christopher Castiglia and Russ Castronovo, v. 76, no. 3, September 2004). He uses an oddly assorted group of figures to map out a grand narrative of how the genius works to accommodate ordinary individuals to "the troubling, potentially shattering phenomena associated with modernity." In the first three chapters Stadler focuses …

Bovine Immune Response To Shiga-Toxigenic Escherichia Coli O157:H7, Mark A. Hoffman, Christian Menge, Thomas A. Casey, William Laegreid, Brad T. Bosworth, Evelyn A. Dean-Nystrom

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

Although cattle develop humoral immune responses to Shiga-toxigenic (Stx⁺) Escherichia coli O157:H7, infections often result in long-term shedding of these human pathogenic bacteria. The objective of this study was to compare humoral and cellular immune responses to Stx⁺ and Stx^- E. coli O157:H7. Three groups of calves were inoculated intrarumenally, twice in a 3-week interval, with different strains of E. coli: a Stx2- producing E. coli O157:H7 strain (Stx2⁺O157), a Shiga toxin-negative E. coli O157:H7 strain (Stx^-O157), or a nonpathogenic E. coli strain (control). Fecal shedding of Stx2⁺O157 was …

Relational Leadership Theory: Exploring The Social Processes Of Leadership And Organizing, Mary Uhl-Bien

Leadership Institute: Faculty Publications

Relational leadership is a relatively new term in the leadership literature, and because of this, its meaning is open to interpretation. In the present article I describe two perspectives of relational leadership: an entity perspective that focuses on identifying attributes of individuals as they engage in interpersonal relationships, and a relational perspective that views leadership as a process of social construction through which certain understandings of leadership come about and are given privileged ontology. These approaches can be complementary, but their implications for study and practice are quite different. After reviewing leadership research relative to these two perspectives I offer …

A Dyadic Examination Of Daily Health Symptoms And Emotional Well-Being In Late-Life Couples, Jeremy B. Yorgason, David Almeida, Shevaun D. Neupert, Avron Spiro Iii, Lesa Hoffman

Department of Psychology: Faculty Publications

This study investigated the link between daily health symptoms and spousal emotional well-being in a sample of 96 older dyads. Higher negative mood and lower positive mood were associated with spousal symptoms in couples wherein husbands or wives reported higher average levels of symptoms. For wives, partner effects were moderated by husbands’ marital satisfaction and illness severity. Specifically, higher husband marital satisfaction and illness severity were associated with higher negative mood and lower positive mood for wives on days where husbands reported higher symptom levels. In their work with later-life families, practitioners and educators should address long-term and daily health-related …

A Soft Landing, Steady Growth, And Accelerating Farm Income, John Austin, Chris Decker, Tom Doering, Ernie Gross, Nick Hernandez, Bruce Johnson, Ken Lemke, Frank Schwarz, Scott Strain, Eric Thompson, Keith Turner

Business in Nebraska

After years of accelerating growth, the U.S. economy achieved a soft landing in 2006. The rate of economic growth remained positive but slowed sufficiently to reduce inflation pressures and the need for further interest rate increases. At the same time the economy remained strong enough to continue the current expansion which has been in place since late 2001. Such a soft landing is vital because it should allow the economy to continue to expand for years to come, but with moderate inflation.

The housing sector played an important role in the U.S. economy’s recent slowdown. Housing prices and con-struction activity …

Identification And Quantitative Studies Of Protein Immobilization Sites By Stable Isotope Labeling And Mass Spectrometry, Chunling Wa, Ronald Cerny, David S. Hage

David Hage Publications

A method was developed for characterizing immobilization sites on a protein based on stable isotope labeling and MALDI-TOF mass spectrometry. The model for this work was human serum albumin (HSA) immobilized onto silica by the Schiff base method. The immobilized HSA was digested by various proteolytic enzymes in the presence of normal water, while soluble HSA was digested in ¹⁸O-enriched water for use as an internal standard. These two digests were mixed and analyzed, with the ¹⁸O/¹⁶O ratio for each detected peptide then being measured. Several peptides in the tryptic, Lys-C, and Glu-C digests gave significantly …

Does Seed-Caching Experience Affect Spatial Memory Performance By Pinyon Jays?, B. Lucas Stafford, Russell P. Balda, Alan Kamil

Papers in Behavior in Biological Sciences

Food-storing birds use spatial memory to find previously cached food items. Throughout winter, pinyon jays (Gymnorhinus cyanocephalus) rely heavily on cached pinyon pine (Pinus edulis) seeds. Because of a recent severe drought, pinyon pine trees had not produced a significant seed crop for several years. Therefore, 1- and 2-year-old birds never had the opportunity to cache and recover seeds and birds 4 or more years of age had not recovered seeds in 3 years. This study examined whether natural but extreme variability in experience might result in differences in abstract spatial memory ability during a non-cache …

Modulational Instability In A Layered Kerr Medium: Theory And Experiment, Martin Centurion, Mason A. Porter, Ye Pu, P. G. Kevrekidis, D. J. Frantzeskakis, Demetri Psaltis

Martin Centurion Publications

We present the first experimental investigation of modulational instability in a layered Kerr medium. The particularly interesting and appealing feature of our configuration, consisting of alternating glass-air layers, is the piecewise-constant nature of the material properties, which allows a theoretical linear stability analysis leading to a Kronig-Penney equation whose forbidden bands correspond to the modulationally unstable regimes. We find very good quantitative agreement between theoretical, numerical, and experimental diagnostics of the modulational instability. Because of the periodicity in the evolution variable arising from the layered medium, there are multiple instability regions rather than just one as in a uniform medium.

Tadaridanema Delicatus (Schwartz, 1927) N. Gen., N. Comb. (Trichostrongylina: Molineidae) Parasite Of Molossidae Bats, Jorge Falcon-Ordaz, Carmen Guzman-Cornejo, Luis Garcia-Prieto, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

On the basis of the revision of the type material of Anoplostrongylus delicatus Schwartz, 1927, and new specimens collected from Tadarida brasiliensis mexicana (Saussure, 1860) in 4 arid localities from Mexico, we describe a new genus (Tadaridanema n. gen.), to which A. delicatus is transferred (as Tadaridanema delicatus (Schwartz, 1927) n. gen., n. comb.). This new genus differs from all other genera included in noplostrongylinae by having ray 2 larger than ray 3. In addition, T. delicatus can be differentiated from the type species of Anoplostrongylus (Anoplostrongylus paradoxus (Travassos, 1918)) because it possess vestibular branches equal in length, cephalic inflation …

The 2006 Nebraska Nest Report, Wayne Mollhoff

Nebraska Bird Review

The drought that began in 1999 continued over most of Nebraska this year, with 7 of the past 8 years receiving lower than normal rainfall. More normal rains fell in April and early May, especially in the central and east, before stopping for most of the summer. Most of the Panhandle and southwest were declared drought disaster areas by early summer, setting the stage in late July for the worst fire season in memory in the Pine Ridge area of the northern Panhandle (Fowler, 2007). Ultimately, 83 of 93 counties were declared part of the drought disaster area. Low water …

Fall Field Report, August-November 2006, W. Ross Silcock

Nebraska Bird Review

First, I want to say how much I appreciate observers' responses to my requests for additional details on various sightings, not just rarities, but early and late dates. It's important to have these details for the archives to help future readers and researchers feel more comfortable with records from our era.

Patterns that were apparent included a generally quiet fall for waterfowl (they were all at Lake McConaughy), but excellent numbers of the rarer two scoters (but NO White-winged!) and a surprising 16 Red-necked Grebes. On the other hand, numbers of staging Western Grebes were down significantly, apparently due to …

Types Of Communication Triads Perceived By Young-Adult Stepchildren In Established Stepfamilies, Leslie A. Baxter, Dawn O. Braithwaite, Leah A. Bryant

Department of Communication Studies: Faculty Publications

This study was an analysis of the kinds of residential parent-stepparent-stepchild triadic communication structures expressed in interviews with 50 college-aged children from established stepfamilies. In an interpretive analysis of the interview transcripts, four communication structures were identified. In the linked triad the stepchild relied on indirect communication with the stepparent through his or her residential parent. The outsider triad was characterized by the stepchild communicating primarily with the residential parent with limited awareness of interdependence with the stepparent. In the adult-coalition triad the stepchild perceived that the residential parent and stepparent had formed a coalition, leading to cautious and distrustful …

Identification Of A Putative Operon Involved In Fructooligosaccharide Utilization By Lactobacillus Paracasei, Yong Jun Goh, Andrew K. Benson, Vicki Schlegel, Jong-Hwa Lee, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

The growth and activity of some Lactobacillus and Bifidobacterium strains are stimulated by the presence of nondigestible fructooligosaccharides (FOS), which are selectively fermented by specific intestinal bacteria. Consumption of FOS, therefore, enriches for those bacteria that possess metabolic pathways necessary for FOS metabolism. In this study, a DNA microarray consisting of 7,680 random genomic library fragments of Lactobacillus paracasei 1195 was used to examine genes involved in the utilization of FOS in this organism. Differential expression profiles between cells grown on FOS and those grown on glucose provided a basis for identifying genes specifically induced by FOS. Several of the …

Prebiotic Galactooligosaccharides Reduce Adherence Of Enteropathogenic Escherichia Coli To Tissue Culture Cells, Kari Schoaf, George L. Mulvey, Glen D. Armstrong, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

Prebiotic oligosaccharides are thought to provide beneficial effects in the gastrointestinal tract of humans and animals by stimulating growth of selected members of the intestinal microflora. Another means by which prebiotic oligosaccharides may confer health benefits is via their antiadhesive activity. Specifically, these oligosaccharides may directly inhibit infections by enteric pathogens due to their ability to act as structural mimics of the pathogen binding sites that coat the surface of gastrointestinal epithelial cells. In this study, the ability of commercial prebiotics to inhibit attachment of microcolony-forming enteropathogenic Escherichia coli (EPEC) was investigated. The adherence of EPEC strain E2348/69 on HEp-2 …
