Effects Of Nanosilver And Silver Nitrate Exposure On Fathead Minnows (Pimephales Promelas) And Zebrafish (Danio Rerio), Adam D. Hawkins

Electronic Theses and Dissertations

Silver nanoparticles (AgNPs) due to their unique antimicrobial properties are among the most widely utilized nanoparticle. Because of the nature of the products that utilize AgNPs, environmental release of AgNPs is inevitable. At greatest risk is the aquatic ecosystem due to known toxicity of the Ag + ion to aquatic organisms. Our goal was to use two fish models, fathead minnows (Pimephales promelas; FHMs) and zebrafish ( Danio rerio; ZFs), to study the effects of AgNPs on gill histopathology, Na+/K+-ATPase immunoreactivity, mucus production, bioaccumulation, particle uptake characterization, gill gene expression, and lethality in varying water parameters in comparison to the …

Childhood Growth In An Oneota Community: Examining Long Bone Growth Differences In The The Juveniles At Norris Farms 36, Whitney Broughton

Electronic Theses and Dissertations

Oneota migration into the central Illinois River valley around ad 1300 resulted in a number of different interactions with Mississippian groups. Milner and colleagues (1991) identified significant numbers of perimortem injuries at the Norris farms 36 cemetery, along with biological markers for poor health, such as cribra orbitalia and porotic hyperostosis. They suggested that the threat of violence may have forced the Oneonta at Morton village to limit subsistence activities to circumscribed areas close to the settlement, thereby reducing the resource base and negatively impacting the health of the community. However, recent research (Bengtson et al. 2012; Bengtson and O'Gorman …

Design And Analysis Of Reconfigurable Sensing Antennas For Wireless Sensing Applications, Qian Qiao

Electronic Theses and Dissertations

Reconfiguration sensing antenna (rsa) is a novel antenna concept, which not only can transmit or receive radio waves but also can sense the surrounding environment. The environment sensing is realized by reconfiguring the antenna's characteristics, such as resonant frequency, and radar cross section (rcs). The rsas possess the advantages of passive and low cost, which make them suitable for the large-scale wireless sensing networks (wsns) deployment. In this dissertation, the rsas concept is demonstrated, and two sensing mechanisms performed in the rsas are investigated. In order to verify these sensing mechanisms, four rsas are designed, analyzed, and measured. All the …

Bottling Hell: Myth-Making, Cultural Identity And The Datil Pepper Of St. Augustine, Florida, Anna Hamilton

Electronic Theses and Dissertations

This thesis interrogates the datil pepper (capsicum chinense) as a potent cultural symbol against a backdrop of heritage tourism in St. Augustine, Florida, widely known as "the nation's oldest city." the datil is a locally popular and regionally unique heirloom pepper endemic to St. Augustine and the surrounding environs. A romantic origin story and local lore are embedded on this spicy pepper, tying it to north Florida's Minorcan population, a group descended from indentured workers brought to the area in the late 1700s. The prominence of this mythology speaks to heritage tourism's demand for consumable cultural emblems, and the datil …

Pcb Effects On Development Of Behavior In Rats, Robert Witte

Honors Projects

Abstract

PCBs were originally used as industrial chemicals in many devices and applications, including electrical capacitors and transformers, lubricants, and sealants in buildings. PCBs have been investigated and their use has been slowly phased out starting in the U.S. in the 1970s. A worldwide ban was put on the use and manufacturing of PCB in 2001, however they remain in the food chain because of their lipophilic properties and their long half-life. Major sources of PCB include wild-life, fish, and other seafood. Individuals exposed to PCB during development can experience negative effects on neurobiological, cognitive, and behavior functioning in both …

Materializing Citizenship: Finance In A Producers' Republic, Robert C. Hockett

Cornell Law Faculty Publications

This invited essay critically assesses a movement of which I consider myself to be part – the movement to “redemocratize” financial institutions in a manner that restores, to non-wealthy citizens, access to basic financial services comparable to those enjoyed by wealthy citizens. I argue that while financial redemocratization of this sort is necessary to the larger project from which it draws most of its meaning – viz that of redemocratizing access to the resources requisite to productive enterprise and meaningful citizenship more generally – it is far from sufficient to this task. We must therefore take special care not to …

Exploring Perceived Benefits Of And Barriers To The Use Of Pet Therapy Dogs In A Private School For Children With Special Needs, Sarah Wodder

PCOM Psychology Dissertations

Evidence-based psychotherapy is becoming an increasingly accepted way for individuals to manage a variety of clinical disorders and psychosocial stressors. Complementary therapies are designed to support, facilitate, or enhance existing treatment strategies. Animal-assisted therapy (AAT) is one such complementary treatment, in which animals are deliberately included in psychotherapeutic treatment plans in order to facilitate pre-designed treatment goals. Current literature suggests that AAT could have a multitude of benefits for both adults and children for an array of disorders and disabilities. Currently, there is a limited understanding of how AAT might contribute to learning and development for children with special needs. …

Specifically, the …

Mrp1: A Target For Hematopoietic Stem Cell Diseases, Cassandra Reiling

Theses and Dissertations--Toxicology and Cancer Biology

Multidrug resistance-associated protein 1 (MRP1) is a member of the adenosine 5’-triphosphate (ATP)-binding cassette (ABC) transporters. MRP1 actively effluxes a variety of endogenous and exogenous substrates from cells, ultimately, working to remove these compounds from the body. MRP1 was initially discovered based on its ability to confer resistance against a variety of chemotherapeutics when overexpressed in cancer cells lines. MRP1 function is important for a number of physiological processes, including regulating cellular and extracellular levels of the anti-inflammatory leukotriene C4 (LTC4) and the antioxidant glutathione (GSH). Our studies have focused on the role of MRP1 in regulating hematopoietic stem cell …

Preparation, Characterization, And Delivery Of Antibodies Binding To A Model Oncogenic Rna, Human Initiator Trna, Jennifer Archer

Electronic Theses and Dissertations

Non-coding RNAs (ncRNAs) account for a higher percent of the genome than coding mRNAs, and are implicated in human disease such as cancer, neurological, cardiac and many others. While the majority of ncRNAs involved in disease were originally attributed to a class of RNAs called micro RNAs (miRNAs) with a small size of only about 19 -24 base pairs, emerging research has now demonstrated a class of long non-coding RNAs (lncRNAs) that have a size of over 200 base pairs to be responsible for gene regulation and other functional roles and have also found to contribute to pathogenesis in humans. …

Creating Constructs Through Categorization: Gender And Race, Joshua Simpkins

Electronic Theses and Dissertations

In U.S. society, the systems of gender and race operate to privilege and oppress individuals based on their location within these systems. All of the interactions an individual experiences as they go about their day-to-day lives are shaped by these interlocking systems. As a result, there is an extensive body of sociological literature addressing how individuals in U.S. society are privileged and oppressed on the basis of their perceived membership in gender and race categories; however, relatively little research exists examining how individuals come to be seen by others as members of gender and race categories in the first place. …

Functional Scaffolding For Musical Composition: A New Approach In Computer-Assisted Music Composition, Amy K. Hoover

Electronic Theses and Dissertations

While it is important for systems intended to enhance musical creativity to define and explore musical ideas conceived by individual users, many limit musical freedom by focusing on maintaining musical structure, thereby impeding the user's freedom to explore his or her individual style. This dissertation presents a comprehensive body of work that introduces a new musical representation that allows users to explore a space of musical rules that are created from their own melodies. This representation, called functional scaffolding for musical composition (FSMC), exploits a simple yet powerful property of multipart compositions: The pattern of notes and rhythms in different …

Training Teaching Assistants To Implement Systemic Teaching Strategies In Preschool Classrooms With Reliability, Rebecca V. Crawford

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

We are currently in an era of accountability, so the need for measuring fidelity of implementation is gaining attention. However, there is little research in the area of fidelity of implementation and an inclusive early childhood classroom. In addition, most of the research is conducted using teachers. This study examined the fidelity of implementation by two teaching assistants using the teaching strategies of time delay and system of least prompts with children with and without disabilities in an inclusive early childhood setting. A multiple-probe design with conditions across two behaviors and across two participants design was used to determine the …

Effect Of Dietary Exposure To Ergot Alkaloids On Contractility Of Bovine Mesenteric Vasculature And Rumen Motility, Amanda M. Egert

Theses and Dissertations--Animal and Food Sciences

Endophyte-infected (E+) tall fescue grass has been associated with fescue toxicosis, a costly syndrome characterized by poor cattle performance and health resulting in significant production losses. The fungal endophyte produces ergot alkaloids, which help the grass thrive in poor conditions but are toxic to mammals. A number of symptoms of fescue toxicosis can be related to vasoconstriction of bovine core, peripheral, and foregut vasculature. The first part of this series of experiments demonstrated ergot alkaloids were also vasoactive in midgut vasculature, with the exception of lysergic acid. Additionally, prior dietary exposure to ergot alkaloids decreased the contractile response of mesenteric …

Interaction Of Isoflavones And Endophyte-Infected Tall Fescue Seed Extract On Vasoactivity Of Bovine Mesenteric Vasculature, Yang Jia

Theses and Dissertations--Animal and Food Sciences

Endophyte-infected tall fescue produces many ergot alkaloids, which have been shown to be vasoconstrictive in various vessel types of bovine. On the other hand, substantial evidence has been reported on the vasodilative effects of formononetin and biochanin A in different vessel types in humans and rats. So, a study was conducted using mesenteric vasculature collected from heifers shortly after slaughter. After 2-h incubation with formononetin (F), biochanin A (B), or an ergovaline-containing tall fescue seed extract (EXT) and their combinations, vessels were mounted in a multi-myograph to determine their ergotamine-induced contractility. Results indicated that F and B at 1 × …

Effect Of Direct-Fed Microbials And Monensin On In Vitro Rumen Fermentation, Sheryl Wingard

Theses and Dissertations--Animal and Food Sciences

The impact of supplying a mixed culture of lactate producing bacteria on in-vitro rumen fermentation of forage- (Experiment 1) and concentrate- (Experiment 2) based diets in the presence and absence of monensin was explored. In experiment 1, interactions between DFM and MON were absent (P>0.10) for gas production and fermentative end products. Gas production and fermentative end products were unaffected by DFM alone (P>0.10). Monensin decreased (P<0.001) CH₄ and NH₃ production, rate and total gas production, as well as total VFA concentration and molar proportions of acetate and butyrate. However, MON increased (P<0.001) proportions of propionate, valerate, isobutyrate and isovalerate. Independently, DFM and MON increased (P<0.001) end point pH. In experiment 2, DFM x MON interactions or tendencies (P=0.07, P<0.01, P<0.01) were present, DFM effects were abated by MON, for rate, total gas production and total VFA concentrations. Acetate:propionate ratio was decreased (P<0.01) with MON and was unaffected by DFM. Ammonia-N concentration was increased (P<0.01) by DFM and unaffected (P=0.75) by MON. Both DFM and MON treatment increased (P<0.01) ruminal pH levels. These studies suggest the effects of DFM and MON of in-vitro fermentation are …

Evaluating Dietary Amino Acid Adequacy In Horses Using Isotopic Techniques, Sara L. Tanner

Theses and Dissertations--Animal and Food Sciences

Little is known about amino acid (AA) requirements in horses despite muscle mass accretion being of importance to an athletic species. Isotope methods for determining AA requirements and whole-body protein synthesis (WBPS) had not been previously used in growing horses. The first study herein was the first to apply isotope methods to determine WBPS in growing horses. In the study, weanling colts received two different levels of crude protein. Whole-body protein kinetics indicated that WBPS was greater when the weanlings were fed the diet with a greater crude protein content (P<0.05). The second study sought to determine a lysine requirement for yearling horses using the indicator AA oxidation (IAAO) method. Despite using six dietary levels of lysine; three above and three below the current recommendation, no breakpoint could be determined. Phenylalanine kinetics were not affected by lysine level (P>0.05), but plasma lysine increased linearly with lysine intake …

The Influences Of Strategic Management On Antitrust Discourse, Hillary Greene, Dennis A. Yao

Faculty Articles and Papers

This article examines how antitrust law and policy can benefit from ideas developed in the academic strategy field. Because accurate assessment and prediction of the effects of firm conduct depend in part on understanding individual firm capabilities, knowledge from the strategy field and other business fields complements the contributions from industrial organization economics (10). These business fields also offer theoretical and empirical challenges to the 10 paradigm, which dominates antitrust analysis. The article begins with a comparison between strategy and 10 and then illustrates how the strategy field can contribute to antitrust merger analysis. The article then assesses the influence …

Voices At The Table: Collaboration And Intertextuality, Sue C. Kimmel, Kathryn Kennedy (Ed.), Lucy Santos Green (Ed.)

STEMPS Faculty Publications

While we often associate reading aloud with children and particularly younger children, the practice of reading aloud has historically been a way for a community to share texts for information and enjoyment. Findings from a year-long study of a school librarian collaborating with a team of second grade teachers demonstrates the value of reading aloud in building background knowledge and vocabulary, modeling, understanding curriculum, creating common texts, and reading for enjoyment. Reading aloud brought other voices to the table in a clear example of intertextuality. Implications are shared for school librarians interested in similar practices as well as future research …

Exposure To Endocrine Disrupting Chemicals And Male Reproductive Health, Hueiwang Anna Jeng

Community & Environmental Health Faculty Publications

Endocrine disrupting chemicals (EDCs) can interfere with normal hormonal balance and may exert adverse consequences on humans. The male reproductive system may be susceptible to the effects of such environmental toxicants. This review discusses the recent progress in scientific data mainly from epidemiology studies on the associations between EDCs and male reproductive health and our understanding of possible mechanisms associated with the effects of EDCs on male reproductive health. Finally, the review provides recommendations on future research to enhance our understanding of EDCs and male reproductive health. The review highlights the need for (1) well-defined longitudinal epidemiology studies, with appropriately …

Anomia Treatment Platform As Behavioral Engine For Use In Research On Physiological Adjuvants To Neurorehabilitation, Diane Kendall, Anastasia Raymer, Miranda Rose, Joellen Gilbert, Leslie J. Gonzalez Rothi

Communication Disorders & Special Education Faculty Publications

The purpose of this study was to create a "behavioral treatment engine" for future use in research on physiological adjuvants in aphasia rehabilitation. We chose the behavioral target anomia, which is a feature displayed by many persons who have aphasia. Further, we wished to saturate the treatment approach with many strategies and cues that have been empirically reported to have a positive influence on aphasia outcome, with the goal being to optimize the potential for positive response in most participants. A single-subject multiple baseline design with replication across eight participants was employed. Four men and four women, with an average …

Eat It: Sex, Food And Women's Writing [Book Review], Marc Ouellette

English Faculty Publications

Simply put, Eat It: Sex, Food and Women's Writing surpasses its rather immodest claims. This is no mean feat, for the editors allow that they have collected short stories, nonfiction shorts and poetry that, as the back claims offers, hinge "on the carnal." More than that, the gathered works purportedly address the ways in which experiencing food entails nothing short of "power, biology, social obligation, experimentation, nourishment, pain and pleasure." The authors treat the topics, ranging from the politics of potatoes to tricks for field dressing deer, with a blend of seriousness and humour befitting the material. What becomes clear …

Evolution Of The Freshwater Sardinella, Sardinella Tawilis (Clupeiformes: Clupeidae), In Taal Lake, Philippines And Identification Of Iits Marine Sister-Species, Sardinella Hualiensis, Demian Willette, Kent E. Carpenter, Mudjekeewis Santos

Biological Sciences Faculty Publications

We identify the sister species of the world's only freshwater sardinella, Sardinella tawilis (Herre, 1927) of Taal Lake, Philippines as the morphologically-similar marine Taiwanese sardinella Sardinella hualiensis (Chu and Tsai, 1958). Evidence of incomplete lineage sorting and a species tree derived from three mitochondrial genes and one nuclear gene indicate that S. tawilis diverged from S. hualiensis in the late Pleistocene. Neutrality tests, mismatch distribution analysis, sequence diversity indices, and species tree analysis indicate populations of both species have long been stable and that the divergence between these two lineages occurred prior to the putative 18th century formation of Taal …

Review Essay: Engaging Feminist Histories, Elizabeth Groeneveld

Women's & Gender Studies Faculty Publications

This review essay considers three recently published texts that centrally engage with the question of how one writes about feminisms and feminist histories in ways that do justice to their complexity and dynamism.
