Virtual Microstructure Generation Of Asphaltic Mixtures, Mohammad Haft-Javaherian

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

This thesis describes the development and application of a virtual microstructure generator incorporated with post-processing image analysis methods that can be used to fabricate a virtual, two-dimensional microstructure of asphaltic mixtures. In the generator, geometrical characteristics such as aggregate gradation, aggregate area fraction, angularity, orientation, and elongation were used to transform data from a three-dimensional (3D) mixture into its two-dimensional (2D) microstructure. The 2D virtual microstructures were generated from real 3D mixture information of asphaltic composites. Resulting virtual microstructures were then compared to real cross-sectional microstructure images obtained from actual samples for validation. Comparison presented a good agreement between the …

Obituary: Jerry Ronald Choate, 1943-2009, Elmer J. Finck, Hugh H. Genoways, Justin D. Hoffman, Carleton J. Phillips, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

Jerry Ronald Choate (1943–2009) had just retired as Director of the Sternberg Museum of Natural History and Professor of Biological Sciences, Fort Hays State University, Hays, Kansas, at the time of his death. Jerry served the American Society of Mammalogists in numerous capacities, including Recording Secretary, First Vice President, and most notably as a member and chair of the Board of Trustees.

The hallmark of Jerry’s life was to turn the ordinary into something magnificent. Whether it was his photography that changed an ordinary landscape into a magnificent masterpiece, or his convincing a reluctant graduate student that they could do …

Preparation And Characterization Of Biomimetic Hydroxyapatite-Resorbable Polymer Composites For Hard Tissue Repair, Kristopher R. Hiebner

Department of Chemistry: Dissertations, Theses, and Student Research

Autografts are the orthopedic “gold standard” for repairing bone voids. Autografts are osteoconductive and do not elicit an immune response, but they are in short supply and require a second surgery to harvest the bone graft. Allografts are currently the most common materials used for the repair of segmental defects in hard tissue. Unlike autografts, allografts can cause an undesirable immune response and the possibility of disease transmission is a major concern. As an alternative to the above approaches, recent research efforts have focused on the use of composite materials made from hydroxyapatite (HA) and bioresorbable polymers, such as poly-L-lactide …

A Comparison Of The Clarendonian Equid Assemblages From The Mission Pit, South Dakota And Ashfall Fossil Beds, Nebraska, Nicholas A. Famoso, Darrin Pagnac

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Mission Pit locality (SDSM V5314), near Mission, South Dakota, has produced a large collection of equid teeth obtained from the Miocene Ash Hollow (=Thin Elk) Formation. Ashfall Fossil Beds (UNSM Ap-116), near Royal, Nebraska, has yielded an extensive collection of equid cranial elements and teeth derived from the Cap Rock Member, Ash Hollow Formation. The two sites are interpreted to be Clarendonian in age [12.5 to 9.0 Ma], but may contain faunal assemblages from differing Clarendonian subages.

The two sites exhibit a notably similar composition of equid genera, including the tribes Equini (Pliohippus, Calippus, and Protohippus …

Review Of Arch Lake Woman: Physical Anthropology And Geoarchaeology. By Douglas W. Owsley, Margaret A. Jodry, Thomas W. Stafford, Jr., C. Vance Haynes, Jr., And Dennis J. Stanford., Daniel J. Wescott

Great Plains Research: A Journal of Natural and Social Sciences

Approximately 10,000 radiocarbon years before present, the body ofa 17- to 19-year-old female, probably associated with the Plainview Culture, was buried on the south side of Arch Lake, located near the present-day border of New Mexico and Texas. The young woman was interred in an extended supine position with a necklace of talc beads low on her neck, a bag containing red pigment and a unifacial stone tool on her left hip, and a bone tool placed on her chest. Her grave remained relatively undisturbed until 1967 when it was exposed, discovered, and carefully excavated by archaeologists. The Arch Lake …

Group Size And Nest Spacing Affect Buggy Creek Virus (Togaviridae: Alphavirus) Infection In Nestling House Sparrows, Valerie A. Brown, Charles R. Brown

Papers in Ornithology

The transmission of parasites and pathogens among vertebrates often depends on host population size, host species diversity, and the extent of crowding among potential hosts, but little is known about how these variables apply to most vector-borne pathogens such as the arboviruses (arthropod-borne viruses). Buggy Creek virus (BCRV; Togaviridae: Alphavirus) is an RNA arbovirus transmitted by the swallow bug (Oeciacus vicarius) to the cliff swallow (Petrochelidon pyrrhonota) and the introduced house sparrow (Passer domesticus) that has recently invaded swallow nesting colonies. The virus has little impact on cliff swallows, but house sparrows are seriously …

Paleoamerican Diet, Migration And Morphology In Brazil: Archaeological Complexity Of The Earliest Americans, Sabine Eggers, Maria Parks, Gisela Grupe, Karl J. Reinhard

School of Natural Resources: Faculty Publications

During the early Holocene two main paleoamerican cultures thrived in Brazil: the Tradição Nordeste in the semi-desertic Sertão and the Tradição Itaparica in the high plains of the Planalto Central. Here we report on paleodietary singals of a Paleoamerican found in a third Brazilian ecological setting – a riverine shellmound, or sambaqui, located in the Atlantic forest. Most sambaquis are found along the coast. The peoples associated with them subsisted on marine resources. We are reporting a different situation from the oldest recorded riverine sambaqui, called Capelinha. Capelinha is a relatively small sambaqui established along a river 60 km from …

A Case Study Of The Community College Baccalaureate: What Happened In Ten Years?, Bonnie S. Hofland

Department of Educational Administration: Dissertations, Theses, and Student Research

A growing number of community colleges are offering bachelor degrees in addition to maintaining their traditional functions. This case study examined one community college that began offering bachelor degrees in 1999. The purpose for conducting the study was to provide a historical “portrait" of Great Basin College, from 1997-98 through 2009-2010, as it developed five baccalaureate programs. Specifically, I explored, through archived data and interviews with 20 administrators and faculty, how offering four-year programs impacted the students, faculty, curriculum, governance, and culture of the community college.

Several conclusions were drawn from the data. The interviewees were adamant Great Basin College …

A Lay Word For A Legal Term: How The Popular Definition Of Charity Has Muddled The Perception Of The Charitable Deduction, Paul Valentine

Nebraska Law Review

In the United States there is a deeply held conviction “that taxpayers who donate to charity should generally not be subject to the same income tax liability as similarly situated taxpayers.” This innate sense about the Internal Revenue Code’s § 170, otherwise known as the charitable deduction, resonates with Americans’ sense of fairness and creates strong barriers to curtailing its function.

This same sense of fairness is tied to the perceived effects of the charitable deduction. Yet, how “charitable” is the charitable deduction, and how charitable do we expect it to be? This Article argues that the discrepancy between the …

Quantifying Articulatory Distinctiveness Of Vowels, Jun Wang, Jordan R. Green, Ashok Samal, David B. Marx

Department of Special Education and Communication Disorders: Faculty Publications

The articulatory distinctiveness among vowels has been frequently characterized descriptively based on tongue height and front-back position; however, very few empirical methods have been proposed to characterize vowels based on time-varying articulatory characteristics. Such information is not only needed to improve knowledge about the articulation of vowels but also to determine the contribution of articulatory imprecision to poor speech intelligibility. In this paper, a novel statistical shape analysis was used to derive a vowel space that depicted the quantified articulatory distinctiveness among vowels based on tongue and lip movements. The effectiveness of the approach was supported by vowel classification accuracy …

New Stable Isotope Record Of Paleoecological Change In The Late Neogene Of The Western Great Plains From Enamel In Large Mammals, Zachary Kita

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

An expansion of C₄ grasslands occurred between 6 and 8 million years ago in the Great Plains of North America, as evidenced by a marked shift to more ¹³C-enriched carbon isotope compositions from large fossil mammal tooth enamel and paleosol carbonates. Prior to this expansion, habitats were comprised of exclusively C₃ vegetation. To explore this problem I present a compilation of bulk stable carbon (δ¹³C) and oxygen (δ¹⁸O) isotope values from a variety of large mammals from 6 localities that span from the late Clarendonian to the late Blancan in Nebraska. As expected, …

When Knowing Just Isn't Enough: Examining The Role Of Moral Emotions In Health Decision Making Using The Theory Of Planned Behavior, Kate Duangdao

Department of Psychology: Dissertations, Theses, and Student Research

A proposed integrated Theory of Planned Behavior (TPB) model aimed to examine the role of moral emotions and two health outcomes: prosocial behaviors and smoking outcomes. Based on Tangney’s work with shame and guilt-proneness, it was expected that those more prone to guilt would engage in more prosocial behaviors and those more prone to shame would engage in more smoking behaviors. Prosocial behaviors were found to be negatively associated with smoking outcomes. However, results suggested that guilt and shame-proneness seem to function similarly in predicting behavioral outcomes. Components within the TPB were generally positively correlated with each health outcome, however …

Importance Of Characterizing Nanoparticles Before Conducting Toxicity Tests, Yi Cong, Chengfang Pang, Lina Dai, Gary T. Banta, Henriette Selck, Valery E. Forbes

Valery Forbes Publications

Rapidly expanding growth in the field of nanotechnology has led to the development of numerous applications of nanomaterials in industrial (e.g., paints, electronics) and consumer (e.g., cosmetics, clothing treatments) products. These engineered nanoparticle (NP)-containing products have, however, the potential to release particles (single or aggregates) or ions by means of wastewater discharge into the aquatic environment. SCENIHR (2006) emphasized that the behavior of NPs is critically dependent on several particle characteristics, including size, surface area and surface reactivity, and that risk assessments for both human health and the environment have to be based on these characteristics. However, in practice, risks …

Blarina Hylophaga (Sorciomorpha: Soricidae), Cody W. Thompson, Jerry R. Choate, Hugh H. Genoways, Elmer J. Finck

University of Nebraska State Museum: Mammalogy Papers

Blarina hylophaga (Elliot, 1899) is a soricid commonly called Elliot’s short-tailed shrew. A short-legged, robust shrew with a long, pointed snout and a short tail; it is 1 of 4 species in the genus Blarina. It occurs throughout most of the Great Plains of the United States, where it inhabits moist, well-drained grassland and riparian areas with deep leaf litter. It is listed as a species of greatest conservation need in Iowa and at possible risk in Texas, which might be due to the limited knowledge of the species throughout its geographic range.

Reassessing The Architecture Of The Health Beliefs Models In Low-Income Diverse Families, Krista B. Highland

Department of Psychology: Dissertations, Theses, and Student Research

Health beliefs contribute to health outcomes. These health beliefs extend to include health beliefs parents have regarding their children’s health. However, the role of parental health beliefs remains unexplored among a low-income population. This study aims to assess these beliefs and the effects they have on child health. Furthermore, this study aims to delineate potential belief differences between socioecological-level groups (e.g. population density, Latino identification, and insurance coverage). The long-term goal is to understand the relationships among various personal health beliefs and parental health beliefs, psychosocial factors, community factors, cultural factors, organizational factors, and healthcare perceptions among this at-risk population. …

Understanding Mesosystemic Influences On Reported Health Among Rural Low-Income Women: A Structural Equation Analysis, Tiffany Wigington

College of Education and Human Sciences: Dissertations, Theses, and Student Research

While ensuring access to health insurance and health care services is important, emerging research indicates that individual health and well-being result from a complex array of environmental, social, and psychological factors. The delineation of how factors of health and well-being unfold and impact rural low-income women is particularly salient for social workers who provide services to rural residents and who work within a rural context. Utilizing components from the ecological systems perspective, this study explored how the factors associated with health risk influenced reported health and mesosystemic processes among rural low-income women. This sample (n=304) for this study was drawn …

Isolation By Distance Explains Genetic Structure Of Buggy Creek Virus, A Bird-Associated Arbovirus, Abinash Padhi, Amy T. Moore, Mary Bomberger Brown, Jerome E. Foster, Martin Pfeffer, Charles R. Brown

School of Natural Resources: Faculty Publications

Many of the arthropod-borne viruses (arboviruses) show extensive genetic variability and are widely distributed over large geographic areas. Understanding how virus genetic structure varies in space may yield insight into how these pathogens are adapted to and dispersed by different hosts or vectors, the relative importance of mutation, drift, or selection in generating genetic variability, and where and when epidemics or epizootics are most likely to occur. However, because most arboviruses tend to be sampled opportunistically and often cannot be isolated in large numbers at a given locale, surprisingly little is known about their spatial genetic structure on the local …

The Evolution Of Prophy Paste, Caren M. Barnes

College of Dentistry: Faculty Publications

Dental hygienists have many products to choose from when deciding which prophy paste is best for each patient. To date, the evidence supporting prophy pastes formulated to remineralize enamel or eliminate dentinal hypersensitivity is somewhat unclear. Most of the research has been conducted in vitro among environments that do not accurately simulate clinical conditions. Additional clinical research performed in vivo is needed to provide the evidence base necessary for effective clinical decision making.

Genetic Variation And Inheritance Of Diapause Induction In Two Distinct Voltine Ecotypes Of Ostrinia Nubilalis (Lepidoptera: Crambidae), Cengis Ikten, Steven R. Skoda, Thomas E. Hunt, Jaime Molina-Ochoa, John E. Foster

Department of Entomology: Faculty Publications

European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), displays a larval diapause in response to short photoperiods and is adapted to a variety of local conditions throughout North America. Hence, the effective photoperiod inducing larval diapause will differ among geographic ecotypes. This study considers the inheritance of photoperiodic larval diapause induction by hybridization and backcrossing two latitudinally distinct ecotypes of the European corn borer collected between 41° N, 96° W and 48° N, 96° W and under a range of photoperiods representative of their respective locations: from 14:10 to 16:8 (L:D) h. The ecotype adapted to a bivoltine habitat (southeastern …
