The relationship between selection at coarse and fine spatiotemporal spatial scales is still poorly understood. Some authors claim that, to accommodate different needs at different scales, individuals should have contrasting selection patterns at different scales of selection, while others claim that coarse scale selection patterns should reflect fine scale selection decisions. Here we examine site selection by 110 woodland caribou equipped with GPS radio‐collars with respect to forage availability and predation risk across a broad gradient in availability of both variables in boreal forests of Northern Ontario. We tested whether caribou selection for forage and avoidance of risk was consistent …

Development Of Self-Adjuvanted Self-Assembling Protein Nanoparticles For Use As Vaccine Candidates, Christopher P. Karch

Doctoral Dissertations

Nanotechnology and nanoparticles are one type of vaccine delivery system. Potentially, the most exciting nanoparticle for vaccine development is our Self-Assembling Protein Nanoparticles (SAPNs). Based off of coiled-coil oligomerization domains, SAPNs self-assemble into particles that are about the size and shape of small icosahedral viruses. Studies have demonstrated that SAPNs are effective vaccine candidates, inducing immune responses as well as protection for malaria, toxoplasmosis, influenza, and SARS. While effective, one missing component for SAPNs is the presence of an immunopotentiator. We have sought to resolve this problem by generating Self-Adjuvanted SAPNs. These SAPNs contain a small concentration of flagellin, a …

Modernism Contested: Gego's Grids And The Aesthetics Of Temporality, Victoria L. Fedrigotti

Theses and Dissertations

This thesis traces Gego’s contestation of art historical modernism through examining her relationship to the modernist grid and to her modernist genealogy of Constructivism, Geometric Abstraction, and Kineticism. These two nonlinear developments subvert the teleological conception of progress presumed by Greenbergian modernism, and bring forth Gego’s own aesthetic conception of temporality.

Claudio Perna, Ca. 1970: The Impossibility Of Wholeness, Silvia Benedetti

Theses and Dissertations

This thesis identifies two main themes in Claudio Perna’s (1938–1997) work: his use of technology to explore self-representation and his interrogation of mapping as means of knowledge. This study also situates Perna’s conceptual work in relation to his field of human geography, in the specific Venezuelan context.

How To Look At Monsters: Staging Female Bodies From The Periphery Of The Seventeenth-Century Spanish World In Baroque Portraiture And Hapsburg Collections, Risa A. Puleo

Theses and Dissertations

This inquiry examines portraits of “monsters”—an early modern term describing those whose bodies challenged socially-constructed categories by deviating from the social norm through differences of race, gender and physical or mental capacity, painted for Hapsburg royals across Europe, who collected specimens, including people, representing the scope of their territories.

Divergent Responses Of Cryptic Invasive Watermilfoil To Treatment With Auxinic Herbicides In A Large Michigan Lake, Syndell R. Parks

Masters Theses

Invasive plants are a major concern for environmental managers. Cryptic invasive taxa present additional challenges because of their potential to respond differently to management efforts. Invasive Eurasian watermilfoil (Myriophyllum spicatum) and hybrid watermilfoil (Myriophyllum spicatum x Myriophyllum sibiricum) cannot be reliably distinguished based on morphological characters and are therefore cryptic taxa. Laboratory studies show that on average, hybrid watermilfoil grows faster, branches more, and is less responsive to standard control measures developed for Eurasian watermilfoil. These laboratory results predict less effective control of hybrid watermilfoil in mixed populations treated uniformly with one of these control measures. However, to date there …

Rnai-Mediated Control Of Aflatoxins In Peanut: Method To Analyze Mycotoxin Production And Transgene Expression In The Peanut/Aspergillus Pathosystem, Renee S. Arias, Phat M. Dang, Victor S. Sobolev

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

The Food and Agriculture Organization of the United Nations estimates that 25% of the food crops in the world are contaminated with aflatoxins. That represents 100 million tons of food being destroyed or diverted to non-human consumption each year. Aflatoxins are powerful carcinogens normally accumulated by the fungi Aspergillus flavus and A. parasiticus in cereals, nuts, root crops and other agricultural products. Silencing of five aflatoxin-synthesis genes by RNA interference (RNAi) in peanut plants was used to control aflatoxin accumulation following inoculation with A. flavus. Previously, no method existed to analyze the effectiveness of RNAi in individual peanut transgenic events, …

Continuous Pth: A Tale Of Two Pathways, Thomas Estus

Doctoral Dissertations

Parathyroid hormone (PTH) is a key factor in bone metabolism, able to stimulate both osteoblasts to cause bone formation and osteoclasts to cause bone resorption. The studies presented herein set forth to examine both the formative and resorptive pathways in light of a newly discovered inhibitory factor, serum amyloid a3 (Saa3). Saa3 is particularly germane to the PTH signaling pathway as it is secreted by cells of the osteoclast lineage in response to PTH stimulation of prostaglandin. Saa3 then enacts its inhibitory effects by acting back onto osteoblasts to inhibit PTH’s ability to stimulate cAMP/PKA signaling. In the absence of …

Performing Conquest And Resistance In The Streets Of Eighteenth Century Potosí: Identity And Artifice In The Cityscapes Of Gaspar Miguel De Berrío And Melchor Pérez De Holguín, Agnieszka A. Ficek

Theses and Dissertations

This thesis examines the ways in which Potosí's two most influential colonial artists represented the urban dynamics of race, class and labor in their depictions of the Andean 'City of Silver' during the eighteenth century, when silver production, profits and population were dramatically declining.

The Status Of Fishes In The Missouri River, Nebraska: Selected Ancient Fishes, Kirk D. Steffensen

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Several ancient fish species have inhabited the Missouri River and its tributaries for thousands of years prior to major mainstem modifications and fragmentation. However post-anthropogenic modifications, populations of these ancient fish species have been highly diminished. Therefore, the objective of this study was to use historic and current ichthyological records to determine the past and present status for Chestnut Lamprey Ichthyomyzon castaneus, Silver Lamprey Ichthyomyzon unicuspis, Bowfin Amia calva, American Eel Anguilla rostrata, and Burbot Lota lota. Currently, these species are rarely captured and perhaps extirpated from Nebraska waters.

Dysregulation Of The Haem-Haemopexin Axis Is Associated With Severe Malaria In A Case-Control Study Of Ugandan Children., Robyn E Elphinstone, Frank Riley, Tian Lin, Sarah Higgins, Aggrey Dhabangi, Charles Musoke, Christine Cserti-Gazdewich, Raymond F. Regan, H Shaw Warren, Kevin C Kain

Department of Medicine Faculty Papers

BACKGROUND: Malaria is associated with haemolysis and the release of plasma haem. Plasma haem can cause endothelial injury and organ dysfunction, and is normally scavenged by haemopexin to limit toxicity. It was hypothesized that dysregulation of the haem-haemopexin pathway contributes to severe and fatal malaria infections.

METHODS: Plasma levels of haemin (oxidized haem), haemopexin, haptoglobin, and haemoglobin were quantified in a case-control study of Ugandan children with Plasmodium falciparum malaria. Levels at presentation were compared in children with uncomplicated malaria (UM; n = 29), severe malarial anaemia (SMA; n = 27) or cerebral malaria (CM; n = 31), and evaluated …

Learning Delays In A Mouse Model Of Autism Spectrum Disorder, Amanda R. Rendall

Master's Theses

Autism Spectrum Disorder (ASD) is a heterogeneous neurodevelopmental disorder with core symptoms of atypical social interactions and repetitive behaviors. It has also been reported that individuals with ASD have difficulty with multisensory integration, and this may disrupt higher-order cognitive abilities such as learning and social communication. Impairments in the integration of sensory information could in turn reflect diminished cross-modal white matter connectivity. Moreover, the genetic contribution in ASD appears to be strong, with heritability estimates as high as 90%. However, no single gene has been identified, and over 100 risk genes have been reported. One of these genes -- contactin-associated-like-protein …

Revisiting Community Water Fluoridation, Jessica Marie Seyfried

Master's Theses

There is a bourgeoning controversy unknown to many surrounding one of the CDC’s top ten public health achievements of the 20^th century. After more than 50 years of implementation, community water fluoridation may not have achieved the declines in caries rates we once thought or hoped for, especially in light of alternative approaches to preventing caries including but not limited to other sources of fluoride supplementation, changes in diet, and tooth brushing behavior.

In fact, a survey of past research highlights the fact that this policy decision may be based on out of date and/or a lack of research …

Evaluation Of Interallelic Waxy, HeteroWaxy, And Wild-Type Grain Sorghum Hybrids, M. K. Yerka, J. J. Toy, Deanna L. Funnell-Harris, Scott E. Sattler, J. F. Pedersen

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

Four near-isogenic Wheatland x Tx430 grain sorghum [Sorghum bicolor (L.) Moench] hybrids differing in allelic status at the Waxy locus were grown in yield trials to determine their potential to expand existing sources of low-amylose starch. The hypothesis tested was that agronomic performance and grain yield do not differ among hybrid genotypes. Hybrids were generated in a two-by-two factorial design using wx^b and wild-type (WT) Wheatland as female parents with wx^a and WT Tx430 as male parents. Yield trials were conducted at two Nebraska locations in 2009 and 2010. No differences were observed for field emergence, but …

In Vitro Formation Of 8-Hydroxy-2'-Deoxyguanosine (8-Ohdg) In Calf Thymus Dna Upon Treatment Of 2'-Deoxyguanosine With Propyl Gallate And 2,6-Di-Tert-Butyl-P-Benzoquinone, Budiawan, Dwi Retno Widiastuti

Makara Journal of Science

Oxidative DNA damage caused by propyl gallate (PG) and 2,6-di-tert-butyl-p-benzoquinone (BHT-quinone, a metabolite of butylated hydroxytoluene (BHT)) was analyzed from the 8-hydroxy-2¢-deoxyguanosine (8-OHdG) formation in calf thymus DNA and DNA base, 2¢-deoxyguanosine (dG). PG in the presence of CuCl2 increased the 8-OHdG formation in calf thymus DNA by around 9.17 times as compared to the control (untreated DNA). In the presence of CuCl2 at 1.28×10-5 M, the 8-OHdG per dG ratio resulting from the reaction of dG with PG at various concentrations (20–150 ppm) ranged from 75.50 to 312.06 8-OHdG per 105 dG. The 8-OHdG formation increased when the PG …

Folklore And Children’S Literature: A Content Analysis Of The De Grummond Children’S Literature Collection, Colleen E. Smith

SLIS Connecting

Folklore can be defined as “context, performance, attitude, cultural tastes, and the like” (Toelken, 1996, p.7). With folktale and fairy tales, these stories embody cultural values and morals, aiding in learning a lesson or to keep intact a cultural tradition. Many works of literature serve as models for studies in folklore, offering literary criticism, while allowing ancient traditions and modern traditions to be explored (Toelken, 1996, p. 391). Additionally, most, if not all, written folklore, folktales, and fairy tales were originally passed down verbally, from one generation to the next; these stories are part of oral histories (Toelken, 1996). Many …

The Impact Of Interactive Music Therapy On The Pediatric Oncology Population, Kristin Moon Orrigo

Senior Honors Projects, 2010-2019

It is an unfortunate truth that a child with cancer will experience pain or anxiety during their battle with illness. Research shows that Interactive Music Therapy is extremely effective at the bedside of hospitalized pediatric cancer patients in reducing pain (Thrane, 2013; Huang, Good, Zauszniewski, 2010; Potvin, Bradt, Kesslick, 2015; Naylor, Kingsnorth, Lamont, McKenever, 2011; Tanriverdi, Aydemir, 2013) and anxiety (Callaghan, Dun, Baron, Barry, 2012; Thrane, 2013; Potvin et al., 2015; Docherty, Cherven, Stegenga, Ferguson, Roll, Stickler, Haase, 2012; Robb et al.,. 2008; Kemper, Bouhairie, Martin, Woods 2008; Tanriverdi, Aydemir, 2013). In cancer centers, the demand is quickly growing for …

Prescription For Critical Thinking: A Discussion Of Psychotropic Medication And Counseling, Barton W. Biggs

Educational Specialist, 2009-2019

This paper examines questions about the safety and efficacy of psychotropic medication, and looks at how these questions should impact the field of counseling. The paper first looks at increasing rates of use of psychotropic medication, and establishes that nearly every clinical mental health counselor will work with clients who are taking or considering taking such medication. The paper next examines the scientific literature and establishes that there is a legitimate basis for questions to be raised about the safety and efficacy of these medications. The paper goes on to establish that there is a foundation in ethical codes and …

Rat Hind Limb Nociceptive Withdrawal Response Depends On Initial Paw Position But Not Stimulus Location, Kimberly Seamon

Senior Honors Projects, 2010-2019

There have been numerous studies in non-human animals on the effect of stimulus location on the NWR and at least a few studies that address the role of initial posture. However, all of these studies were conducted in anesthetized, decerebrated, or spinalized mammals. Since descending modulation and long loop reflexes may influence the NWR, the anesthetized spinalized/decerebrated animal may not be an adequate model of normal animals. Therefore, the primary aim of this study was to determine the effect of the stimulus location and initial paw position on the direction and magnitude of the nociceptive withdrawal response to heat stimulus …

Ability Of Skin Bacteria On The Panamanian Frog Species, Craugastor Fitzingeri, To Inhibit The Fungal Pathogen Batrachochytrium Dendrobatidis, Tiffany N. Bridges

Senior Honors Projects, 2010-2019

An emerging infectious disease caused by the fungus Batrachochytrium dendrobatidis (Bd) is leading to global amphibian declines and is threatening the biodiversity of amphibians. Bd susceptibility varies among individuals, species, and populations perhaps due to defensive mechanisms such as symbiotic skin microbes. Some species of amphibians such as Craugastor fitzingeri, a terrestrial frog native to Central America, continue to persist in Bd-positive environments in Panama. My study focused on identifying antifungal bacterial isolates and determining the culturability of the bacterial community on 15 individuals of C. fitzingeri. Morphologically distinct isolates were challenged against Bd in …

Pattern Discovery In Dna Using Stochastic Automata, Shweta Shweta

Master's Projects

We consider the problem of identifying similarities between different species of DNA. To do this we infer a stochastic finite automata from a given training data and compare it with a test data. The training and test data consist of DNA sequence of different species. Our method first identifies sentences in DNA. To identify sentences we read DNA sequence one character at a time, 3 characters form a codon and codons form proteins (also known as amino acid chains).Each amino acid in proteins belongs to a group. In total we have 5 groups’ polar, non-polar, acidic, basic and stop codons. …

Tangled Up: Gendered Nationhood In Indo-Caribbean Indenture Narratives, Alison Klein

Anthurium: A Caribbean Studies Journal

Novels that explore the British imperial system of indentured labor in the Caribbean often contain the trope of a relationship developing between a British man in power and a female Indian laborer. This essay explores the use of this relationship as a metaphor for Britain’s colonial relationship with India in two novels by contemporary Indo-Caribbean authors, David Dabydeen’s The Counting House and Sharlow’s The Promise. The Counting House and The Promise use this metaphor to attack the racist interventions of imperialism and indenture, but the novels also maintain the more conventional views of gender that were concretized under these …

Buddhist Phenomenology And The Problem Of Essence, Jingjing Li

Comparative Philosophy

In this paper, I intend to make a case for Buddhist phenomenology. By Buddhist phenomenology, I mean a phenomenological interpretation of Yogācāra’s doctrine of consciousness. Yet, this interpretation will be vulnerable if I do not justify the way in which the anti-essentialistic Buddhist philosophy can countenance the Husserlian essence. I dub this problem of compatibility between Buddhist and phenomenology the ‘problem of essence’. Nevertheless, I argue that this problem will not jeopardize Buddhist phenomenology because: 1) Yogācārins, especially late Yogācārins represented by Xuanzang do not articulate emptiness as a negation but as an affirmation of the existent; 2) Husserl’s phenomenological …
