Modular Inheritance Of Color Pattern In Lake Malawi Cichlid Fishes, Jennifer Roscoe

Renée Crown University Honors Thesis Projects - All

This study attempts to elucidate the mechanisms that underlie the evolution of pigmentation patterns among Lake Malawi cichlids. For decades researchers have sought to provide a theoretical model of cichlid speciation based on the evolution of male nuptial patterns and female preferences, yet our understanding of how color patterns change is limited. Here, we performed exploratory statistical analyses on an F₂ hybrid population to characterize the inheritance of color traits. Specifically, we sought to uncover patterns of modularity and levels of integration among color traits. Because cichlids are sexually dimorphic we did our analyses on males and females separately. …

Elevating Student Comprehension Through Repeated Read-Alouds, Lisa Ventress

Education Masters

There has been a vast amount of research dedicated to the positive benefits of reading aloud to students. However, lacking in the current research is the effect of repeated read-alouds on student comprehension. This action research attempts to answer the question “How does the level of reading comprehension change with repeated read-alouds?” This research focused on three 3 rd grade students in a suburban school. Methodology included reading picture books multiple times and analyzing student’s oral and written responses. Data analysis indicates that as a student’s familiarity with the story increased, so does their level of understanding. This implies that …

Demography Of The Monocled Cobra (Naja Kaouthia) In The Central Region Of Thailand., Apinya Chaitae 1977-

Electronic Theses and Dissertations

Naja kaouthia is a significant species because it feeds primarily on agricultural pests, causes human mortality, and is commercially exploited. Understanding the life history and demography of harvested populations is essential to providing guidelines for proper management. This study was conducted within two rice fields in central Thailand. I found that all age classes of N. kaouthia primarily prey on rats. Prey size increases ontogenetically with snake size. Besides rats and mice, first year snakes feed on frogs. Adults add snakes, lizards, fish, birds, and bird's eggs. Young cobras grow significantly faster than older cobras and the growth rate did …

Application Of Existing Appropriate Technology To Small Communities In Honduras's Opalaca Mountains, Adrian Beirise

Mechanical Engineering Undergraduate Honors Theses

In a 2009 trip to the Opalaca Mountain region of Honduras, a need was identified for appropriate technology solutions to three key issues: housing improvements related to Chaga's Disease, indoor smoke reduction, and pure water. Through research regarding the problems, the local area, and candidate solutions, a set of three solutions was found. This includes corrugated steel roofing, vented or simple adobe rocket stoves, and solar disinfection.

A Positive Feedback Synapse From Retinal Horizontal Cells To Cone Photoreceptors., Skyler L. Jackman, Norbert Babai, James J. Chambers, Wallace B. Thoreson, Richard H. Kramer

Journal Articles: Ophthalmology

Cone photoreceptors and horizontal cells (HCs) have a reciprocal synapse that underlies lateral inhibition and establishes the antagonistic center-surround organization of the visual system. Cones transmit to HCs through an excitatory synapse and HCs feed back to cones through an inhibitory synapse. Here we report that HCs also transmit to cone terminals a positive feedback signal that elevates intracellular Ca(2+) and accelerates neurotransmitter release. Positive and negative feedback are both initiated by AMPA receptors on HCs, but positive feedback appears to be mediated by a change in HC Ca(2+), whereas negative feedback is mediated by a change in HC membrane …

Integration Of Refractory Periods In The Administration Of Low-Magnitude Mechanical Signals Increases Mesenchymal Stem Cell Numbers In The Bone Marrow, Kofi Appiah-Nkansah

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

High-frequency, low-magnitude mechanical signals (LMMS) applied exogenously as low-intensity vibrations (LIV) have been shown to bias mesenchymal stem cell (MSC) differentiation towards osteoblastogenesis at the expense of adipogenesis. Recent in-vitro work has indicated that refractory periods allow additional benefit from these mechanical signals when scheduled into the loading routine. Work is presented here from three distinct 6-week experiments conducted to investigate the role of refractory periods allowed in the administration of LMMS in an in-vivo animal model. Results from the first experiment using 7-week old male C57BL/6J mice suggested that multiple animal handling had an adverse effect on bone morphology, …

Estimating Load Distribution Across The Radius And Ulna In Human And Non-Human Primates, Molly Elmer

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The hominoid wrist joint has changed substantially during the course of primate evolution. One of these changes is the retraction of the ulna from direct contact with the carpals and the insertion of a triangular fibrocartilaginous disc. This change permits a greater degree of mobility at the wrist in apes and is functionally linked to suspensory behaviors. However, the implications of this more mobile wrist joint on how loads are distributed from the hand to the forearm across the wrist joint remains unclear. The goal of this study is to investigate forearm loading by estimating how loads may be distributed …

Transgenic Crops, Environmental Contamination, And Peasant (De)Mobilization In Argentina, Pablo Lapegna

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Based on archival research and ethnographic fieldwork in northeast Argentine province of Formosa, this dissertation examines the dynamics of popular mobilization and demobilization in cases of environmental contamination. Drawing on the sweeping advance of genetically modified (GM) soybeans in Argentina I reconstruct and compare different responses of peasants to agrochemical exposures to address the following question: Why, when facing an environmental onslaught, do people from the same community sometimes react by organizing transgressive protests while at other times failing to engage in disruptive action? The analytic goal is to explain the ways in which people think, feel, and act (or …

Reading Nation And The Poetry Of Robert Frost, Anthony Theodore Sovak

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Robert Frost once said, I want to be a poet for all sorts and kinds Such an aim reflects, in part, Frost's embrace of Emerson's view of the poet, . the poet is representative. He stands among partial men for the complete man, and apprises us not of his wealth, but of the commonwealth The national overtones implicit in the term commonwealth resonate with Frost's attempts to make poetry analogous to nation for each individual in what was and is a very diverse nation. One of Frost's biggest challenges in getting both professors and farmers to read and identify with …

The Clown Paintings Of Jack Butler Yeats, Cliona Mccolgan Stack

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This thesis explores the clown paintings of Jack Butler Yeats with particular emphasis on those painted between 1920 and 1950. Yeats was interested in circus performances from a very young age. In general, his clown paintings seem to capture traditionally showy and exuberant images of both clown and circus. However, they also reveal Yeats' personal sense of the painter as clown. Laughter (who laughs, the permanent grimace) and the symbolism of the rose are significant in establishing the artist as a clown figure. Moreover, the idea of the clown also spoke to the arrival of the modern era. The balancing …

Alternatives For Youth: A Mental Health Perspective, Carolyn Anne Steinman

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Since the 1980's, the common practice in handling juvenile justice involved youth in the United States has been with punitive sanctions and institutional placement. The general agreement among policy makers, politicians and juvenile justice professionals is that there is a better way to help these young men and women than with institutional placement or detention. It has been shown that most youth involved in the juvenile justice system can be better served by community based supports grounded in evidence based principles and practices. The purpose of this study was to discover the factors associated with successful outcomes and failures for …

Mechanisms Of Endoplasmic Reticulum Stress-Induced Cell Death, Erica Marie Ullman

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In cells, incorrectly folded proteins or compromised protein turnover induce cellular stress known as endoplasmic reticulum (ER) stress. Significantly, ER stress plays an important role in numerous physiological and pathological conditions, including degenerative diseases and cancer. In an attempt to resolve ER stress cells activate a response known as the unfolded protein response (UPR). While, initially a protective response, the UPR can induce cell death if ER stress is not overcome. As the precise molecular mechanisms that regulate ER homeostasis and UPR-related cell death remain elusive, I focused my initial studies on understanding these processes. In the course of this …

Breaking Icons: Passivity And Asexuality In Representations Of The Three Graces And The Renaissance Madonna, Nina M. Pascal

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This thesis will examine my artistic practice in relation to a feminist critique of pop cultural imagery through the lens of historical/theological constructs of beauty and passivity. I will look specifically at the ideals of feminine beauty and virtue embedded in classical archetypes such as the Three Graces and the Renaissance Madonna. Discussion of the thesis work will also be situated in relation to the history and symbolic connotations of the Black Madonna. | 41 pages

Opening The Industry Playbook: Myths And Truths In The Debate Over Bpa Regulation, Thomas Mcgarity, Rena I. Steinzor, Matthew Shudtz, Lena Pons

Faculty Scholarship

For the last two decades, scientists have amassed evidence that bisphenol A (BPA) poses a threat to human health.  Although scientists have targeted BPA as a public health concern, plastics industry lobbyists have attempted to thwart the efforts of federal, state, and local authorities to reduce exposure to BPA.  This paper reviews the major arguments advanced by the plastics industry and debunks them as “myths” that public health officials must reject.  The five topics covered include:  the myth of scientific consensus on safety; the myth that only studies complying with “Good Laboratory Practices” guidelines are adequate for making regulatory decisions; …

Combating Antibiotic Resistance Through Development Of A Novel Antimicrobial Delivery Vehicle, Alex Hatch

Undergraduate Honors Capstone Projects

A thermoreversible gel for antimicrobial agent delivery would provide a novel platform suitable for medical applications from persistent infections arising from localized biofilms. Thermoreversible gels could be used to coat medical implants, to inject for subdermal treatments, or to implement in topical applications. FDA approved Pluronics® form thermoreversible gels and certain Pluronics® display inherent varying degrees of antimicrobial activity. Pluronics® have been shown to affect efflux pumps, and reduce ATP levels within the bacterial cell. In combination with antibiotics and other pharmaceuticals, Pluronics® have been used to sequester drugs and act as a delivery vehicle. With advances in nanomedicine, nanoparticles …

Application Of Habitat And Occupancy Modeling To A Wood Duck Next Box Program, Jason D. Carlisle

Undergraduate Honors Capstone Projects

Programs to augment wood duck (Aix sponsa) nesting habitat by providing artificial nest boxes are commonly implemented. In northern Utah, where such programs are relatively new, I proposed a method to identify sites suitable for deployment of next boxes through a combination of habitat and occupancy modeling using site-specific, biotic, and abiotic, data collected from 105 next boxes over one nesting season in Cache County, Utah. An inductive habitat model was first developed which identified possibly suitable habitat (8.74% of county) based on proximity to hydrologic features. Next, based on comparing competing single-species, single-season, occupancy models using a modified Akaike's …

Crossing Borders: Cultural And Linguistic Passages In The Poetry Of Pat Mora And Gary Soto, Amber Christine Bowden

Undergraduate Honors Capstone Projects

Poets Pat Mora and Gary Soto have long been a presence in anthologies citing their multicultural content, yet their work has not been placed as part of the classroom canon. By leaving their work out of the classroom, we have lost the benefit of their diverse poetry. As the demographics of Utah shift, including works such as Mora and Soto’s becomes more essential for student success. In a close textual analysis of seventeen poems by Mora and Soto we can see that each poet uses a variety of themes to frame their verse. Not only does an overall analysis show …

Ultrasound As An Aversive Stimulus For Use With Rats: A Novel Model Of Aversive Control, Brandon Norlund

Undergraduate Honors Capstone Projects

Negative reinforcers serve to maintain or increase behavior through the removal of an aversive stimulus. The primary method of studying negative reinforcement in non-humans has been through the use of electrical shock. While this method has proven to be reliable, many negative reinforcers that humans and non-humans encounter do not elicit tactile pain. Therefore, the purpose of this study was to explore a novel, non-human animal model of aversive control without the use of electrical shock as the negative reinforcer. A considerable amount of research has shown that various strains of rats find ultrasonic tones of certain frequencies and amplitudes …

Stratigraphic, Microfossil, And Geochemical Analysis Of The Neoproterozoic Uinta Mountain Group, Utah: Evidence For A Eutrophication Event?, Dawn Schmidli Hayes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several previous Neoproterozoic microfossil diversity studies yield evidence for a relatively sudden biotic change prior to the first well‐constrained Sturtian glaciations. In an event interpreted as a mass extinction of eukaryotic phytoplankton followed by bacterial dominance, diverse assemblages of complex acritarchs are replaced by more uniform assemblages consisting of simple leiosphaerid acritarchs and bacteria. Recent data from the Chuar Group of the Grand Canyon (770‐742 Ma) suggest this biotic change was caused by eutrophication rather than the direct effects of Sturtian glaciation; evidence includes total organic carbon increases indicative of increasing primary productivity followed by iron speciation values that suggest …

Determining Profitability Strategies For Various Retained Ownership Enterprises In Utah, Matthew H. Hirschi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the price of corn now over $6 per bushel, and with feedlot total cost per pound of gain now approaching $1.00 per pound of gain there are new incentives to try and add weight to calves outside of feedlots. The question then arises of how to add weight to a calf in the most economical manner. There are many different feeding programs to consider. However, with few exceptions, the cheapest way to add weight outside of a feedlot usually involves the calf grazing for an extended period of time. Winter pasture grazing, wheat pasture grazing and corn stalk grazing …

Development Of A Beef Flavor Lexicon And Its Application To Compare Flavor Profiles And Consumer Acceptance Of Grain- And Pasture-Finished Cattle, Curtis A.J. Maughan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Flavor lexicons are used in sensory evaluation to determine the flavor profile of a food product. The objective of this study was to develop a flavor lexicon for cooked beef, which can then be used in various projects relating to beef quality such as studies investigating animal diet, marinating, ageing, or other enhancements. A descriptive panel of 10 people was used to develop a flavor lexicon of 18 attributes, including astringent, barny, bloody, brothy, browned, gamey, grassy, juicy, fatty, livery, metallic, oxidized, roast beef, and the five basic tastes (bitter, salty, sour, sweet, and umami). In contrast to other studies …

Understanding Teacher Users Of A Digital Library Service: A Clustering Approach, Beijie Xu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research examined teachers' online behaviors while using a digital library service—the Instructional Architect (IA)—through three consecutive studies. In the first two studies, a statistical model called latent class analysis (LCA) was applied to cluster different groups of IA teachers according to their diverse online behaviors. The third study further examined relationships between teachers' demographic characteristics and their usage patterns. Several user clusters emerged from the LCA results of Study I. These clusters were named isolated islanders, lukewarm teachers, goal-oriented brokers, window shoppers, key brokers, beneficiaries, classroom practitioners, and dedicated sticky users. …
