  1. An Investigation Into the Spatial Distribution of Streamwater Chemistry Along the Great Miami River and Role of Land Use Type

    Schwieterman, Neill
    Previous studies have shown that the Great Miami River watershed is a top contributor to nutrient load into the Mississippi River and ultimately to the Gulf of Mexico. High nutrient content corresponds to higher algal bloom rates, which can be devastating to environments and economies. Streamwater chemistry in the watershed has been studied extensively previously, however, a geospatial dataset of the scale studied here has never been collected before, which can provide insight into how the streamwater chemistry changes spatially. The land use type of the upper Great Miami River is predominantly agricultural, with 75.3% of the total upper watershed...

  3. Talking in Tongues: Exploring French and Québécois Identity Through Dialogue in Music

    Gulick, Amelia
    L’Académie Française was founded in 1635 by Cardinal Richelieu under King Louis XIV to decide what words constitute the French language. This linguistic standard establishes a foundation for the cultural standards of those for whom speaking French is a defining factor of their identity. My research explores the relationship between the Academy’s preservation of a French language standard and the variations of that standard employed by actual speakers in communication and self-definition. Pop music is a particularly interesting battle ground because it is a pivotal component of culture that bridges language and culture gaps alike. This is the medium through...

  4. Some Bolivians Wear Bonnets and Babushkas: A Family Story of Mennonites in South America

    Richter, Michal
    My mother's side of the family is from a relatively closed cultural and religious group of Mennonites who lived in Paraguay and later Bolivia. Because Mennonites in this region are not culturally or ethnically Bolivian, they are seen as foreigners by the Bolivian public, even though the majority of Mennonites in Bolivia (including my family) have/had Bolivian citizenship. This thesis explores how living in Bolivia and Paraguay was meaningful for my family and how it affected they way that they self-identify. I argue that my family's Bolivian identity extends beyond their citizenship and includes their memories, stories, language, and practices.

  5. They Talk of Days for Which They Sit and Wait: Abbas, Netanyahu, and the Abandonment of Moderation in Modern Israeli-Palestinian Relations

    Fisher, Tophie
    The primary aim of this thesis is to explore what influences governability in polarized societies; specifically, why democratic leaders move from moderation to intransigence on policy proposals. It argues that there are two main factors making for un-governability in polarized societies. The first is the constraint placed on leaders’ choices by the force of public opinion, which precludes those leaders from compromising with one another. Public opinion alone is not sufficient to explain this dynamic, however, as public opinion remains largely stable in the medium to long term while the actions and preferences of leaders can change drastically in the...

  6. Women of Science Fiction in the 1970s

    Hamparian, Matt
    The 1970s were an important time not just for science fiction, but also in the fight for gender equality. Published science fiction, as well as science fiction fan fiction of the 1970s did not provide an accurate or realistic representation of women. This led to many writers to use their pens as a mode to create stories that pushed limits of what people thought of in regards to gender equality. These writers created empowered but importantly realistic female characters that were starkly different than the majority of female characters in science fiction at the time. If we view literature as...

  7. Effortful control as a moderator of the association between attachment insecurity and worry

    Ewert, Michelle
    Recent work shows that worriers high in effortful control (EC; a measure of self-regulatory capacity) are able to avoid anxious arousal despite worrying by constraining their worry to a verbal mode of thinking. In contrast, worriers low in this capacity tend to worry in images, which engenders a constant high level of anxious arousal. These two styles are similar to two styles of adult attachment insecurity: avoidant versus anxious insecurity. Despite similarities, EC’s moderating ability of the association between worry and adult attachment insecurity has not been adequately researched. This study tested the hypothesis that which style of insecurity an...

  8. Tag retention and mortality in inland reservoir channel catfish

    Strahan, Madelyn
    Channel catfish (Ictalurus punctatus) is a popular sport fish that is native to Ohio and routinely stocked in reservoirs by the Ohio Department of Natural Resources-Division of Wildlife (ODNR-DOW). Toward helping the ODNR-DOW evaluate its stocking program, we experimentally tested the use of an internal, coded-wire tag (CWT) as a method for marking juvenile channel catfish that are released from the hatchery such that they can be differentiated from wild-produced channel catfish. The retention rate of CWTs and their effect on individual growth and mortality remain largely unexplored for channel catfish. Both attributes were quantified and compared between the two...

  9. The development and characterization of neural-specific continuous cell lines in Drosophila melanogaster

    Hura, Nanki
    Neurodegenerative diseases affect millions of Americans and are caused by the deterioration of neurons in the central nervous system (CNS). The mutations that cause these neurodegenerative diseases have been modeled in Drosophila melanogaster (fruit fly) transgenic lines that produce flies with neurological defects mirroring the human pathology. Meanwhile, continuous cell lines have transformed biomedical research, making it possible to study biological systems on a scale requiring large numbers of similar cells. However, there is a lack of continuous cell lines of neuronal lineage in Drosophila melanogaster available in the scientific community that would allow for the modeling of neurodegenerative diseases...

  10. The Girl, the Jew, and the Maus: Holocaust Narratives in Controversial Media

    Chivington, Lauren
    The Diary of a Young Girl, Maus, and “The Standover Man” in The Book Thief are all unconventional depictions of the Holocaust in that they depart from traditional literary form (diary, graphic novel, and cartoon palimpsest). They have all received scrutiny over the years, however they have value as art as well as potential use as educational tools for children because of the varying levels of minimalism used in their unique media styles. While there is a wealth of research about the Holocaust, as well as a good amount of scholarship on the validity of Holocaust survivor’s narratives, the topic...

  11. Investigation of Copper Nanoparticle and Bimetallic Catalysts for Electroreduction of Carbon Dioxide

    Byrne, Sean
    Increasing global population and energy needs are draining sources of fossil fuels at an unsustainable rate and have affected global climate in a shocking manner. The development of renewable energy sources is underway, but these suffer from variable returns. The amount of energy derivable from the sun and wind varies greatly month to month, day to day, and even between day and night. This problem necessitates the development of better energy storage mechanisms, so that excess energy can be captured and used at times when energy production is low. Carbon dioxide (CO2) electroreduction is a promising solution to these problems....

  12. It’s Complicated: Empowering Friendships in Charles Brockden Brown’s Ormond and Pierre Choderlos de Laclos’s Dangerous Liaisons

    Miley, Coral
    In the late eighteenth century, there was a lot of anxiety going because people were trying to figure out who they were supposed to be and how their relationships should reflect that. In 1782 France, before the French Revolution, Pierre Chonderlos de Laclos published his seduction novel Dangerous Liaisons, which tells the story of a friendship/partnership of a male and female aristocratic seducers and how their friendship destroys each other. The friendship between Valmont (man) and Merteuil (woman) did not last because crossing gender roles to have the other sex's characteristics were not going to work and the social order...

  13. Exploration for He-3

    O'Reilly, Bryan
    As an essential component in the cleanest and most efficient form of fusion, Helium-3 (He-3) has the potential to produce incredible magnitudes of energy. However, naturally occurring He-3 only makes up 1.37 parts per million of He on Earth. The U.S. stockpile of He-3 has gradually decreased since 2001, with the price of He-3 jumping from 200 to 2,000 USD per liter. This reduced supply is largely due to the Department of Homeland Security’s demand for neutron detection systems along our borders following the events of September 11th 2001. Lacking an atmosphere, the Moon’s surface is only partial shielded from...

  14. Comparing the Weathering Environment of Permian and Modern Antarctic Proglacial Lake Sediments: Mineralogical and Geochemical Study

    Brewster, Shelby
    The Antarctic continent has been in a polar to subpolar position since the Permian period. Although it has experienced milder climates over this time period as evidenced by corals in the fossil record, Antarctica did undergo extensive glaciation during the Permian. This is based on the abundance of Permian tillites (sedimentary rocks derived from glacier tills) found in the Transantarctic Mountains. In this research, I have compared Permian age proglacial lake sediments that are associated with tilites to modern proglacial lake siltstones and mudstones from Antarctica. This was done to determine the climate, especially the amount of glacier melt that...

  15. Optimization of growth and imaging techniques for Medicago truncatula and investigation of root hair nuclear positioning during early rhizobial infection

    Beigel, Katherine
    Legumes establish mutualistic relationships with endosymbiotic nitrogen-fixing rhizobia, which develop and dwell within nodules at the plant's roots. Rhizobia present in the legume's edaphic environment respond to compounds secreted by the plant with Nodulation (Nod) factors. The legume's root hair tips swell in response to these Nod factors, followed by additional cellular changes of the root hair that eventually coordinate infection thread (IT) formation, including curling of the root hair tip around a rhizobium. One of the suspected changes in the initial stages of nodulation is the movement of the root hair nucleus to the root hair tip around the...

  16. Coping with climate change: exploration of metabolic acclimation across generations in a tropical fish.

    Hadick, Steve
    Human-induced climate change is altering the environment, presenting survival challenges to many organisms. In aquatic environments, rising water temperature is among the most prevalent manifestations of climate change stress. When faced with water warming, one way for populations to persist is for its individuals to acclimate to the new temperature. However, the potential for acclimation may be limited, especially in tropical species that likely evolved in a narrow range of environmental conditions. Herein, we seek to determine the capacity for cross-generational acclimation in Julidochromis ornatus, a tropical cichlid species endemic to, but common in, Lake Tanganyika (East Africa). A previous...

  17. The Effect of a Gender Lens on the Political Socialization of Adolescent Girls

    Fillingim, Shannon
    Women's participation in government matters tremendously to the well-being of a nation, yet women still face multiple societal and cultural obstacles as they strive to achieve the goal of full participation in the political arena. The most troubling of these barriers is the perception that women have of themselves as being less qualified than men to engage in political life. In this study, researchers evaluated the effect of a gender lens in a seminar discussion program on the political self-esteem of middle school students. Participants were randomly sorted into two groups. Before each discussion session, participants read a short news...

  18. Functional Validation of MicroRNAs Correlated with Second Biochemical Recurrence After Post-Prostatectomy Radiation in Prostate Cancer

    Andrews, Kathryn
    Prostate cancer (PCa) is one of the most common cancers and the second leading cause of cancer-related death in the U.S. (American Cancer Society, 2017). While treatment strategies for PCa rely primarily on radical prostatectomy (RP), more than one-third of men receiving this treatment experience relapse of the cancer phenotype. Also known as biochemical recurrence, this relapse is defined by a PSA rise of >.2 ng/mL at least twice, or clinical progression demonstrated by local, regional, or distant recurrence as noted via imaging (CT, PET, or bone scan) (Bell, 2015). Patients experiencing this biochemical failure therefore require salvage radiation therapy...

  19. The Implications of "Unmoored" Young Men: Youth Bulges and Protests in an African Context

    Lazar, Mircea
    Much research has considered the effects of the presence of large youth populations in various areas on conflict. The literature lacks a clear verdict, although some have suggested the existence of a significant link between youth bulges and political violence. My research seeks to examine the connection between the presence of large populations of people between the ages of 15 and 24 and protest activity. Unlike previous studies, the scope of this project is limited to the experience of Sub-Saharan Africa, and the youth bulge is tabulated differently. The data for this research was collected from various databases of relevant...

  20. A Mathematical Network Model of Ischemic Stroke

    Sarkar, Monica
    Stroke is a major cause of morbidity and mortality in the United States, with one stoke occurring every forty seconds. About eighty-seven percent of all stokes are ischemic, in which a blood vessel to the brain is blocked, resulting in an energy crisis and subsequent disruption of ion gradients. As a result, waves of recurrent spreading depolarizations (RSDs) start to spread throughout the penumbra. Eventually, extracellular glutamate builds up and leads to excitotoxicity, swelling and death of brain cells. The purpose of this research is to better understand the dynamics of the RSDs that have been associated with glutamate accumulation...
