The Identification Of Quantitative Trait Loci For Sucrose And Stachyose Content In Soybean Seed, Ailan Zeng

Graduate Theses and Dissertations

Sucrose is a desirable sugar in soybean seed that affects the quality and taste of soyfoods, while stachyose is a non-digestible sugar that induces flatulence in non-ruminant animals. Therefore, soybean cultivars with high sucrose and/or low stachyose would be valuable for soyfood and meal markets. The objectives of this study were to identify quantitative trait loci (QTL) or genes associated with seed sucrose and stachyose content using simple sequence repeat (SSR) or single nucleotide polymorphism (SNP) markers. A low sucrose line, MFS-553, was crossed with a high sucrose plant introduction, PI 243545, to develop the sucrose QTL mapping population. A …

A Way Out: The History Of The Outing Program From The Haskell Institute To The Phoenix Indian School, Alexandria L. Gough

Graduate Theses and Dissertations

From the earliest years of the United States, its leaders wrestled with the perceived need to assimilate Indian peoples into American society. Many believed that Indians in their "natural" condition were cultural primitives incapable of taking part in national life. However, with proper guidance they could be elevated to a level of civilization that would allow them to join the national family. After the conclusion of the Indian Wars in the 1880's, the United States government began to address the continued "Indian" problem by establishing Indian boarding schools. Indian children attended school to learn to behave as white, Christian and …

In The Gutter: Comix Theory, Chase Gregory

Faculty Journal Articles

Comix illustrate queerness, literally, both in the comics ‘gutter’ (the space between panels), and in the ‘stutter’ of the repeated frame. The gutter in comics makes clear that narrative can continue (in the form of reproductive futurity) only inasmuch as we continue to suture together gaps in narrative (the gaps of queer jouissance) through the ‘imperative of figuration’ and the compulsion to create meaning. The gutter and repetition stand in relation to deconstructionist ideas about the slippage inherent in meaning, but also have implications for our understanding of Lacanian orders (see David Ault’s work on comics and Lacan). The comics …

The Future Of Citizen Science: Emerging Technologies And Shifting Paradigms, Greg Newman, Andrea Wiggins, Alycia Crall, Eric Graham, Sarah Newman, Kevin Crowston

Information Systems and Quantitative Analysis Faculty Publications

Citizen science creates a nexus between science and education that, when coupled with emerging technologies, expands the frontiers of ecological research and public engagement. Using representative technologies and other examples, we examine the future of citizen science in terms of its research processes, program and participant cultures, and scientific communities. Future citizen‐science projects will likely be influenced by sociocultural issues related to new technologies and will continue to face practical programmatic challenges. We foresee networked, open science and the use of online computer/video gaming as important tools to engage non‐traditional audiences, and offer recommendations to help prepare project managers for …

Bmp Efficiency In An Institutional Area: Minimizing The Impacts Of Water Pollution Using A Stormceptor For Water Quality Improvement, Jameieka Price

Multidisciplinary Studies Theses

Urbanization can negatively impact water quality due to increasing impervious surfaces, which ultimately increases the hydrologic and contaminant load during rain events. Stormwater runoff contains high concentrations of contaminants that accumulate on the impervious surfaces and discharge into local water bodies, affecting aquatic life, recreational usages, aesthetic appearance, and possibly drinking water supply. Best Management Practices (BMPs) are important to minimizing and reducing the amount of water pollution that is found in stormwater runoff. Buffalo State Campus (BSC) is in an urbanized area and currently holds a National Pollutant Discharge Elimination System (NPDES) Permit to control stormwater runoff by implementing …

Understanding The Success And Failure Of Oyster Populations: Periodicities Of Perkinsus Marinus, And Oyster Recruitment, Mortality, And Size, Thomas M. Soniat, John M. Klinck, Eric N. Powell, Eileen E. Hofmann

CCPO Publications

Ten-year time series (1992 to 2002) of salinity, Dermo disease, and size-class structure and mortality measured for an eastern oyster (Crassostrea virginica) population at a reef in Bay Tambour, Terrebonne Parish, LA, were analyzed using wavelet techniques to determine dominant frequencies and correlations. Along the Gulf Coast of the United States, Dermo disease (caused by Perkinsus marinus) responds to the El Nino-Southern Oscillation (ENSO) climate signal through its response to salinity. During the La Nina portion of ENSO, decreased rainfall leads to an increase in salinity, which triggers a rise in Dermo disease prevalence and intensity, producing increased oyster mortality. …

Determining The Trophic Role Of Gulf Menhaden (Brevoortia Patronus) Using Carbon And Nitrogen Stable Isotopes, Zachary Olsen

Master's Theses

Gulf menhaden (Brevoortia patronus) play multiple roles in the Gulf of Mexico coastal ecosystem as filter feeders and as an important food source for many recreationally and economically important finfish. Gulf menhaden also support a large commercial fishery, and little is known about the impact of fishing on the role of this species as a filter feeder in the food web. This study examines the spatial, temporal and ontogenetic dynamics of food selectivity and trophic role observed in Gulf menhaden. The most important dietary item for juvenile fish was found to be phytoplankton (75.7% dietary composition) while that of subadults …

Lactic Acid Production Using Sweet Potato Processing Waste, Irene Pagana

Graduate Theses and Dissertations

Organic waste generated from industrial sweet potato canning is estimated to be 30% of incoming raw material. This waste contains carbohydrates (sugars and starch) that could be used as substrates for the production of useful compounds via fermentation (e.g. lactic acid), resulting in the production of value-added products. The goal of this research project is to produce a substrate from the sweet potato processing waste material that supports the growth of lactic acid bacteria, which results in the production of lactic acid. The sweet potato waste product was characterized, and found to contain 16.5% solids. The solids components were 18.5% …

Defending The Multiple Realization Argument Against The Identity Theory, David Barrett

Graduate Theses and Dissertations

A classic argument in the philosophy of mind is that the identity theory is false because mental state types are multiply realized in brain state types. In this dissertation I provide a detailed elaboration of the argument and a defense of it against a few of its prominent contemporary critics. Finally I offer empirical evidence from inter-species differences in humans and monkeys, and also from a case of extensive neural plasticity, which shows that mental state types are multiply realized in brain state types.

Motivational Inequality: Prevention Goals Induce More Effort Than Promotion Goals, Jennifer Marie Pattershall-Geide

Graduate Theses and Dissertations

Regulatory focus theory describes two motivational strategies--promotion and prevention focus--that may be employed during goal directed action. Although a theory of motivation, there is no research examining differences in effort between promotion and prevention focus. Two studies are presented which test the hypothesis that goals pursued with a prevention focus, with its emphasis on duties, responsibilities, and avoidance of negative outcomes, will induce more effort than goals pursued with a promotion focus, which emphasizes hopes, ideals, and achieving positive outcomes. In addition, several potential mediators and moderators of this effect were examined. In Study 1, students who completed an essay …

"It Was Awful, But It Was Politics": Crittenden County And The Demise Of African American Political Participation, Krista Michelle Jones

Graduate Theses and Dissertations

Despite the vast scholarship that exists discussing why Democrats sought restrictive suffrage laws, little attention has been given by historians to examine how concern over local government drove disfranchisement measures. This study examines how the authors of disfranchisement laws were influenced by what was happening in Crittenden County where African Americans, because of their numerical majority, wielded enough political power to determine election outcomes. In the years following the Civil War, African Americans established strong communities, educated themselves, secured independent institutions, and most importantly became active in politics. Because of their numerical majority, Crittenden's African Americans were elected to county …

Maternal Environment And Fescue Cultivar Effects On Growth, Development, And Fertility Of Beef Heifers, Jennifer Denyse Patterson

Graduate Theses and Dissertations

Eighty Brahman-influenced cows (5.6 BCS) were assigned to graze common bermudagrass (CB) or toxic tall fescue (E+) during a 60-d breeding season. Body condition (BC) was assessed at d 0, 30, and 60 of breeding season. Cows were managed to achieve marginal (4.2 BCS) or good (6.3 BCS) BC during last trimester. Heifer birth and weaning (WW; 7 to 8 mo) weights were recorded. The Angus sired heifers were weighed and randomly assigned to E+ or non-toxic (Novel) tall fescue at 9 to 10 mo of age for 190d. Heifer weight, growth data, and antral follicle count (AFC) were collected …

Comparative Response Of Different Broiler Genotypes To Dietary Nutrient Levels, Franco Javier Mussini

Graduate Theses and Dissertations

ABSTRACT

Three studies were conducted to evaluate how the broiler has changed over the years due to intense genetic selection. Four different broiler genotypes, one unselected since the 1950's (HER) representing the old meat-type bird and three current strains (Ross 308, Ross 708, and a test product (TY)) were studied. Differences in growth, morphometry, and response in performance and processing yield to different nutrient levels were studied.

Experiment 1 evaluated growth and morphometric analysis. Birds of each strain were killed weekly from day 7 to day 56, necropsied and cut up parts and organs weighed. Measurement of small intestine segments …

Graduate Theses and Dissertations

Tabletop roleplaying is a dynamic and flourishing hobby that has become increasingly accessible to a wide variety of participants. The games themselves, as well as the gaming subculture, offer players a number of personal and Social benefits that continue to enrich their lives long after they leave the table. Using Goffman's theories of Dramaturgy and Frame Analysis, this paper seeks to examine the positive impact of gaming in three key areas.

The first is an analysis of the subculture which includes the evolution of the games, the growth and diversification of the roleplaying community, and the current shift in stereotypes …

The Relationship Between Middle Level School Science Programs And A Residential Environmental Learning Center, Ryan Mathew Walker

Graduate Theses and Dissertations

A multiple case study investigation examines the relationship between a residential environmental learning center and six schools that attend their program. Pre-experience interviews were conducted with teachers to gain understanding of how they integrate the residential experience with formal classroom instruction. On-site observations of teacher participation during the program provided insight into how they foster student learning during the experience. A student questionnaire was used to reveal students' perceptions of three areas of interest: 1) most meaningful aspects of the experience, 2) most confusing aspects of the experience and 3) topics they would like to know more about. These data …

Consumer Sensory Preferences And Willingness-To-Pay For Nutraceutical-Rich Fruit, Lydia Lawless

Graduate Theses and Dissertations

Health-oriented juices are prime candidates for the nutraceutical market due to their inherent healthfulness and convenience. Fruits such as açaí berries, blueberries, blackberries, black cherries, Concord grapes, cranberries, and pomegranates are rich in potentially health-supporting polyphenolics, which makes the juices of these fruits attractive for nutraceutical optimization. The compositional, sensory, and stability properties of blueberry, blackberry, and Concord grape juice blends were explored in an extended shelf-life study. Initially, 100% blueberry juice had the highest total monomeric anthocyanins (67.40 mg/100mL), 100% blackberry juice had the highest total phenolics (249.24 mg/100mL), and 100% Concord juice had the highest polymeric color (23.21%). …

The second objective was to evaluate the effects of time (0600, 1200, 1800, and 2400 h) of fecal sampling on the prediction of FO and DMD. A replicated …

High School Policy Debate As An Enduring Pathway To Political Education: Evaluating Possibilities For Political Learning, Ellen C. Zwarensteyn

Masters Theses

This paper addresses the role competitive high school policy debate participation has on key developmental markers of political learning. As identified by the Carnegie Foundation’s Political Engagement Project (PEP), political learning includes political knowledge and understanding, political identity, and the development of political skills. Based in interviews with former high school debaters, the results of this study suggest there may be a transformative, politically enduring and engaging experience surrounding policy debate.

Using grounded theory to extract analysis of debaters’ experiences, this study demonstrates how sustained competitive high school policy debate experience directly advances political learning and should be a tool …

Aquatic Mesohabitats: Abiotic And Biotic Comparisons In A Sand-Dominated, 3rd Order, Michigan Stream, Edward M. Krynak

Masters Theses

Mesohabitats are visually distinct areas within a stream that provide habitat heterogeneity and increase invertebrate diversity. As such, mesohabitats represent an important spatial scale that underpins the emergent properties, ecology, and ecosystem structure and function of a stream. Within a Western Michigan stream, woody debris, macrophyte beds, and organic matter pools, were examined to determine if visual distinction also relates to a significant difference in abiotic and biotic parameters. Habitats were sampled from July, 2010 – June, 2011 for chemical-physical characteristics including velocity, temperature, pH, conductivity, turbidity and organic matter. Biotic sampling occurred during the same time span and included …

Experiment 1 evaluated the responses to Lys and Met on live performance of young broiler chickens from 0 to 18 d of age. The mean amino acid ratios to Lys suggested by literature values were used in the formulation based on the Ideal Protein Concept. Six levels of Lys and eight levels of supplemental Met were used in the diets resulting in a …

Algorithms For Optimizing Cross-Overs In Dna Shuffling, Lu He, Alan M. Friedman, Chris Bailey-Kellogg

Dartmouth Scholarship

DNA shuffling generates combinatorial libraries of chimeric genes by stochastically recombining parent genes. The resulting libraries are subjected to large-scale genetic selection or screening to identify those chimeras with favorable properties (e.g., enhanced stability or enzymatic activity). While DNA shuffling has been applied quite successfully, it is limited by its homology-dependent, stochastic nature. Consequently, it is used only with parents of sufficient overall sequence identity, and provides no control over the resulting chimeric library.

Results: This paper presents efficient methods to extend the scope of DNA shuffling to handle significantly more diverse parents and to generate more predictable, optimized libraries. …

Factors Affecting The Distribution And Survival Of Endangered American Burying Beetles, Nicrophorus Americanus Olivier, Jessica Jurzenski

Department of Entomology: Dissertations, Theses, and Student Research

The disappearance of the federally endangered American burying beetle (Nicrophorus americanus Olivier) over most of its range is poorly understood, which is why the identification and evaluation of conservation measures is important. The presence and distribution of all carrion beetles in Nebraska was first reported to help understand where American burying beetles (ABBs) occur to aid in creating a habitat suitability model for the Sandhills ecoregion and to locate suitable experiment areas. There are 18 Nebraska counties with records of ABB presence in the last 15 years. The final habitat suitability model performed well with an AUC value above …

Host-Microbe-Diet Interplay: Dietary Modulation Of The Gut Microbiota In Relation To Health, Inés Martínez

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Vertebrates are associated with trillions of bacteria, with the densest populations residing in the large intestine. The symbiosis between vertebrates and their gut microbiota has resulted in important implications of the gut microbiome on host health. Diet is an important factor that shapes gut microbiota composition, and because of the interplay between host-microbiome-diet, dietary strategies that modulate gut microbiome structure are deemed a relevant tool to improve host health. However, gaps in knowledge exist with respect to these interactions, and it is essential to obtain a mechanistic understanding of how these relations take place to develop successful therapeutic strategies that …

River Otter (Lontra Canadensis) Home Range, Habitat Use, Overnight Movement, And Survival In The Platte River Of Nebraska, Samuel P. Wilson

School of Natural Resources: Dissertations, Theses, and Student Research

River otters (Lontra canadensis) are native to Nebraska but were extirpated by the early 1900s. The Nebraska Game and Parks Commission (NGPC) reintroduced river otters during 1986­–1991 to restore the species in the state but little is known regarding the habitat needs and status of this high profile threatened species. To provide information for management I conducted research to determine home range, habitat use, overnight movement distance, and annual survival of river otters in the central Platte River of Nebraska.

I trapped, implanted telemetry transmitters, and tracked 18 river otters during 2006–2009. I obtained 996 locations and constructed …

Amyloid-Beta42 Toxicity Reduction In Human Neuroblastoma Cells Using Cholera Toxin B Subunit-Myelin Basic Protein Expressed In Chloroplasts, Alexandra Ayache

HIM 1990-2015

Alzheimer's disease (AD) is an age progressive neurodegenerative brain disorder, affecting 37 million people worldwide. Cleavage of amyloid precursor protein by ?- and ?-secretase produces the amyloid-beta (A?) protein, which significantly contributes to AD pathogenesis. The A? aggregates, formed at the surface of neurons and intracellularly, cause neurotoxicity and decrease synaptic function. Inhibiting or degrading A? accumulation is a key goal for development of new AD treatments. Evidence shows that human Myelin Basic Protein (MBP) binds to and degrades A? thereby, preventing cytotoxicity. A potential method for oral drug delivery that will allow plant-derived bioencapsulated MBP to pass through intestinal …
