The Impact Of Temperature On The Early Stages Of The Development Of The Body Axis In The Model Species Astyanax Mexicanus (Teleostei: Characidae), Sara Mohammad Alharbi
The Impact Of Temperature On The Early Stages Of The Development Of The Body Axis In The Model Species Astyanax Mexicanus (Teleostei: Characidae), Sara Mohammad Alharbi
College of Science and Health Theses and Dissertations
Environmental fluctuations can change the phenotypic traits of ectotherms. Ectotherms such as fishes are very susceptible to changes in temperature. Recent studies on adults of the Mexican tetra, Astyanax mexicanus, indicate that variation in temperature during development significantly impacts vertebral number and body shape. Since vertebral number and somite number are related, I examined whether temperature significantly impacts somitogenesis and the early development of the body axis in this species. Fertilized eggs of the surface form of lab-reared Astyanax mexicanus were subjected to temperature treatments of 20°C, 24°C, and 28°C, and fixed hourly as they developed until they hatched. Embryos …

Understanding The Differences In The Radioprotection Activity Of The Vitamin E Tocols, And Their Implications In Developing Effective Radioprotectors, Ujwani Nukala
Theses and Dissertations
With the increased use of ionizing radiation for various purposes like radiotherapy, nuclear power generation, sterilization, the likelihood of intentional or unintentional radiation exposure is increasing and there is an unmet need for effective radiation countermeasures that are safe, efficient, easy to administer. Vitamin-E is a well-known antioxidant, consisting of eight different vitamers, including four tocopherols (α, β, γ and δ) and four tocotrienols (α, β, γ and δ), which are structurally very similar and collectively known as tocols. Though alpha-tocopherol has been considered the primary form of vitamin-E and extensively studied, tocotrienols have recently gained attention for their superior …
Susceptibility Of Borrelia Burgdorferi Morphological Forms To Chemical Antimicrobials, Ann-Aubrey Kaiwilani Reid
Susceptibility Of Borrelia Burgdorferi Morphological Forms To Chemical Antimicrobials, Ann-Aubrey Kaiwilani Reid
Theses and Dissertations
Borrelia burgdorferi is the etiological agent of Lyme disease. Not much is known about the susceptibility of this organism to chemical disinfection. Current antimicrobial susceptibility test methods, such as those published by the American Society for Testing and Materials (ASTM), usually require assessment of the number of colony forming units (cfu) of growing organisms on plates following exposure to an agent. For fast-growing organisms, plates are ready for counting 1-2 days post plating, while several weeks may be needed for slower growing organisms. Spirochetes, like B. burgdorferi are difficult to grow on solid media and typically require long incubation periods, …
Investigation Of Thymidine Kinase 1 In Cancer Progression, Eliza Esther King Bitter
Investigation Of Thymidine Kinase 1 In Cancer Progression, Eliza Esther King Bitter
Theses and Dissertations
Understanding cancer biomarkers for diagnosis and prognosis leads to improved patient treatments and care. This thesis addresses the relevance of thymidine kinase 1 (TK1) as a cancer biomarker and the role of TK1 in cancer progression. Worldwide, cancer leads to more than 12 million deaths annually. In the United States alone, each year over 1.5 million cases will be diagnosed and over half a million persons will die. The most prevalent cancer types include skin, lung, breast, prostate, and colon. TK1 is known to be present in the serum of patients with multiple cancer types, including lung, breast, colon and …
Evaluating Climate Change Impacts On Drinking Water Reservoirs And Wastewater System Resilience In Connecticut, U.S.A., Cristina Mullin
Evaluating Climate Change Impacts On Drinking Water Reservoirs And Wastewater System Resilience In Connecticut, U.S.A., Cristina Mullin
Doctoral Dissertations
Societies depend on the proper functioning and resilience of critical infrastructure systems including those for drinking water and wastewater, but these systems are vulnerable to natural and anthropogenic stressors. For example, wastewater systems are especially susceptible to extreme weather events while drinking water systems are vulnerable to diminished source water quality — both of which can disrupt proper functioning. Climate change and human development, economic problems, and pollution further challenge water system resilience. Despite the criticality of these systems and known vulnerabilities, little scholarship exists that aims to interrogate their resilience. This dissertation attempts to narrow this gap in the …

Out Of The Ashes: Ecological Resilience To Extreme Wildfire, Prescribed Burns, And Indigenous Burning In Ecosystems, Christina Eisenberg, Christopher Anderson, Adam Collingwood, Robert Sissons, Christopher Dunn, Curtis Edson, Et Al.
Michigan Tech Publications, Part 1
Until Euro-American colonization, Indigenous people used fire to modify eco-cultural systems, developing robust Traditional Ecological Knowledge (TEK). Since 1980, wildfire activity has increased due to fire suppression and climate change. In 2017, in Waterton Lakes National Park, AB, the Kenow wildfire burned 19,303 ha, exhibiting extreme fire behavior. It affected forests and the Eskerine Complex, a native-grass prairie treated with prescribed burns since 2006 to reduce aspen (Populus tremuloides) encroachment linked to fire suppression and bison (Bison bison bison) extirpation. One year post-fire, the Kenow wildfire caused vigorous aspen sprouting, altered stand structure to an early-seral …

Developing A Transfection Method For Didymium Iridis, Uriel Adolfo Baray
Developing A Transfection Method For Didymium Iridis, Uriel Adolfo Baray
College of Science and Health Theses and Dissertations
The plasmodial slime mold and member of Mycetozoa, Didymium iridis, has been studied in a variety of contexts such as RNA editing (Traphagen et al., 2010; Hendrickson and Silliker, 2010a; Hendrickson and Silliker, 2010b), mitochondrial inheritance (Silliker et al., 2002), biological speciation (Betterley and Collins, 1983; Clark et al., 1991) and mating competency (Shipley and Holt, 1982). Further studies are hindered by the lack of a transfection protocol, which would allow for gene manipulation in D. iridis (hereafter Didymium). Transfection methods developed in the related slime molds, Physarum polycephalum (Burland et al., 1993) and Dictyostelium discoideum (Fey et al., 1995; …
Songbird Use Of Problem-Solving Feeders In Urban And Rural Areas, Kayce Miller
Songbird Use Of Problem-Solving Feeders In Urban And Rural Areas, Kayce Miller
College of Science and Health Theses and Dissertations
Behavioral flexibility is important for animals to adapt to novel situations in their environment. It has been suggested that birds living in complex environments (e.g., urban areas) should be more flexible than conspecifics in less complex environments. Birds are a particularly well studied group, where novel foraging problems are used to assess flexibility and problem-solving performance of urban and rural animals of the same species; however, this is most frequently done in a lab setting with wild-caught birds originating from different habitats. Using a field-based method to test problem-solving performance should give additional insight into other factors influencing birds’ flexibility. …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers
Lactate produced by muscle during high-intensity activity is an important end product of glycolysis that supports whole body metabolism. The lactate shuttle model suggested that lactate produced by glycolytic muscle fibers is utilized by oxidative fibers. MCT4 is a proton coupled monocarboxylate transporter preferentially expressed in glycolytic muscle fibers and facilitates the lactate efflux. Here we investigated the exercise capacity of mice with disrupted lactate shuttle due to global deletion of MCT4 (MCT4−/−) or muscle-specific deletion of the accessory protein Basigin (iMSBsg−/−). Although MCT4−/− and iMSBsg−/− mice have normal muscle morphology and contractility, only MCT4−/− mice exhibit an exercise intolerant …

“Dengue Hemorrhagic Fever” is the topic selected for the Scientometric study to assess the responsibilities of the global scientists through the measurement of the impact of their research publications. “Dengue Hemorrhagic Fever” affects the health of the society and particularly the young generation are suffering a lot and many of them destined to “Early Death”. The Scientometric study in this research reveals that only 646 publications were published from 2009 to 2018, which means the research contribution on “Dengue Hemorrhagic Fever” is very low. The country wise publications show that “India” leads the table with more number of publications than …
Using Paleosols To Reconstruct Past Environments Before, During And After Periods Of Anatomically Human Migration At Gona, Ethiopia, Kevin Takashita-Bynum
Using Paleosols To Reconstruct Past Environments Before, During And After Periods Of Anatomically Human Migration At Gona, Ethiopia, Kevin Takashita-Bynum
Steeplechase: An ORCA Student Journal
Environmental change is thought to have driven dispersals of Anatomically Modern Humans (AMH) out of Africa, yet the precise landscape context of these migrations remains unclear. Furthermore, river-based archives of paleoenvironment during periods of dispersal are scarce. Gona, an area in northeastern Ethiopia with one of the most continuous records of East African Paleolithic and Neolithic archaeology, contains abundant Middle to Late Pleistocene river deposits interbedded with volcanic ash. This study examines the physical and chemical changes of 11 fossilized soils (paleosols) extracted from Gona’s paleoanthropological sites that range in age from the Middle to the Late Pleistocene (~380-11 ka). …
Keep The Faith Not The Guilt: Demonization Of Sex Workers, Jessica Hodges
Keep The Faith Not The Guilt: Demonization Of Sex Workers, Jessica Hodges
Steeplechase: An ORCA Student Journal
Previous research shows that religiosity and attitudes about sexual topics are strongly correlated and typically negative. That is, as religiosity increases, views toward sexual topics tend to become more conservative or generally more negative in valence. However, current research also suggests that one’s sexual guilt may be the mediating influence in the relationship between religiosity and negative sexual attitudes. The present study seeks to replicate and extend research that examined the extent to which an individual's religiosity and sexual guilt influence their perspective of pornography and sex workers (Study 1). To replicate this (Study 2), a survey containing relevant measures …

The Shapes Of Solidarity Through Difference, Bella Brown
The Shapes Of Solidarity Through Difference, Bella Brown
Acta Cogitata: An Undergraduate Journal in Philosophy
The following paper will track the subtle and not-so-subtle differences between various forms of feminism, specifically the differences between Indigenous and white feminism. Though the differences can outnumber the similarities, I do not see this as a discouragement for forming intercultural bonds for a peaceful coexistence, in fact this is the opportunity for solidarity to change the perception and reach of feminism as a movement. Feminism has the potential for reaching a broader audience without minimizing the differences of separate groups. This paper does not call for the aggregation of different groups in order to further the goals of white …
Political Obligation And Lockean Contract Theory, Samantha Fritz
Political Obligation And Lockean Contract Theory, Samantha Fritz
Acta Cogitata: An Undergraduate Journal in Philosophy
In John Locke’s Second Treatise of Government, he presents his notion of social contract theory: individuals come together, leave the state of perfect freedom, and consent to give up certain rights to the State so the State can protect its members. He grounds duties and obligations to the government on the basis of consent. Because one consents to the State, either tacitly or expressly, one has consented to taking on political obligations owed to the State. Locke also notes that individuals can withdraw consent and leave the State. This paper challenges the view that political obligation can exist under …

Rawls, Climate Change, And Essential Goods, Gloria Li
Acta Cogitata: An Undergraduate Journal in Philosophy
Climate change is one of the most important social and environmental justice issues of the 21st century. As such, it deserves serious treatment by John Rawls, perhaps the most important social justice theorist of the 20th century. In this paper, I first discuss Rawls’ conception of a well-ordered society presented in A Theory of Justice and how climate change may be incorporated in his principles of justice as an intergenerational savings problem. Then, I present a characterization of environmental goods like clean air and clean water as a special kind of good in Rawlsian justice and argue that this is …

The aim of this study is to investigate the mediating role of perceptions of collective efficacy in the relationship between teachers’ professional burnout and organizational commitment. The study group consisted of 377 teachers working at different levels of education in central districts of Konya. Data were obtained by using Demographic Information Form, Collective Teacher Self-Efficacy Scale, Organizational Commitment Scale and Maslach Burnout Inventory. The relationships between the variables were analysed by using Structural Equation Modeling. Our results indicate that teachers’ perceptions of burnout affected both their organizational commitment and perceptions of collective efficacy negatively. It was found that perceptions of …
Effects Of Active Sitting On Reading And Typing Task Productivity, Claire Doroff, Emily Langford, Ronald L. Snarr Jr.
Effects Of Active Sitting On Reading And Typing Task Productivity, Claire Doroff, Emily Langford, Ronald L. Snarr Jr.
International Journal of Exercise Science
International Journal of Exercise Science 12(5): 1216-1224, 2019. Increased sedentary behavior and reduced physical activity among children and adults has led to the advent of various active devices to combat these behaviors. Active sitting, consisting of modified chairs or stability balls, allows the body to stay dynamic while seated. While research has evaluated the health benefits of active sitting, minimal research has shown the effects of active sitting on productivity in adult populations. The purpose was to evaluate the effects of various chairs (active versus non-active) on typing and reading task productivity. Twenty adult participants performed typing and reading tasks …

Feasibility, Acceptability, And Preliminary Efficacy Of A Recess-Based Fitness Intervention In Elementary School Children, Christine W. St. Laurent, Sarah Burkart, Sofiya Alhassan
International Journal of Exercise Science
International Journal of Exercise Science 12(4): 1225-1243, 2019. Although fitness may benefit cognition in youth, most attention has been given to cardiorespiratory fitness despite the health benefits of muscular fitness. Few studies have examined interventions that incorporate both cardiorespiratory and muscular fitness or have been offered during school recess. Furthermore, most fitness intervention studies examining cognitive outcomes have not reported on implementation information. The purpose of this pilot study was to examine the feasibility, acceptability, and preliminary efficacy on fitness and cognition of a recess intervention in elementary school children. Two schools were randomized to either a 3-month cardiorespiratory and …
Revealing The Resistant Capital Of Cambodian Youth: Using Photovoice As A Tool For Advocacy And Policy Change, Erin L. Papa
Revealing The Resistant Capital Of Cambodian Youth: Using Photovoice As A Tool For Advocacy And Policy Change, Erin L. Papa
Journal of Southeast Asian American Education and Advancement
This paper explores the use of Photovoice as a tool for uncovering or developing resistant capital (Yosso, 2005) with youth for language education policy change. Using data from a Youth Participatory Action Research (YPAR) study on the relationships and tensions among the home, community, and school linguistic and social practices of emergent bilingual Cambodian youth in an urban district in the northeastern U.S., I argue that the development of resistant capital depends on various contextual and demographic factors. The Cambodian youth, who have been educated in a recursive bilingual environment (García, 2009) and are involved in a youth-led community organization …
