  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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....

  7. 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...

  8. 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...

  9. 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...

  10. 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...

  11. 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...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. Perceived Causes of Mental Illness and Stigma by Association

    Ross, Anna
    People linked with stigmatized others often face similar social and psychological effects to those with whom they are tied. This phenomenon is referred to as stigma by association. Previous research demonstrates the spreading of general negative attitudes accompanying stigmatized people to those with whom they are associated. In the current study, I examined stigma by association regarding people with mental illness and their friends and family. Research participants were given information highlighting either a genetic cause for Schizophrenia or an environmental cause. Then, participants evaluated someone described as linked to a person with Schizophrenia but with varying degrees of environmental...

  17. The Holodomor and the Ukrainian Diaspora: Historical Narratives in a Changing World

    Pabst, Stavroula
    In the early 1930s, a famine often called the Holodomor took place in Ukraine, and millions of people died. In recent decades, many, particularly the Ukrainian diaspora around the world, have suggested the Holodomor was genocide against the Ukrainian people by the Soviet government, and several countries have recognized the famine as such. No scholarly consensus exists, however, as to whether the Holodomor was genocide. This project therefore focuses on the connection between the Ukrainian diaspora in the West and its advocacy for recognition of the Holodomor as genocide despite a lack of consensus on the subject. To investigate, many...

  18. Western Perceptions of Eastern Romans

    McAdams, Kaelyn
    After the reign of Theodosius I the Roman Empire split into two halves: the eastern half and the western half. When barbarian groups threatened the Western frontiers of the empire, the eastern army failed to aid the west in order to salvage Roman territory. As a result, a former region of the Western Roman Empire in North Africa was taken over by Vandals. Even Rome, the capital of the western Empire, was penetrated by the Gothic army, and was forced to integrate them into Roman politics to remain stable. This integration of barbarian groups, or rather non-Romans, into high status...

  19. The Role of Construal Level in Attentional Bias Toward Temptation

    Engle, John
    Inducing a mindset of abstraction, i.e. high-level construal, increases people’s performance in various measures of self-control (Fujita & Han, 2009; Fujita & Roberts, 2010; Kentaro Fujita et al., 2006). This has been found with both explicit attitudes towards tempting stimuli and evaluative associations with tempting stimuli. The current research seeks to extend this effect further, investigating whether construal level may affect automatic deployment of attention. Following work in the realm of addiction, which linked temptation strength with attentional bias, we tested whether construal manipulation may affect which objects attention is directed to. To induce high-level or low-level construal, we used...

  20. Dosimetry Comparison of Gamma Knife and External Beam Radiation Therapy on Brain Tumors

    Klinker, Cody
    The practice of stereotactic radiosurgery (SRS) dates back to 1951 with Swedish Neurosurgeon Lars Leksell. However, in an age where cancer diagnosis and treatment has become so prevalent for our society, results from clinical techniques such as SRS have become more significant. The two most commonly used methods for performing SRS are Gamma Knife (GK) and External Beam Radiotherapy/Linear Accelerator (LINAC). While the two methods have been clinically performed independently, very few attempts to compare the applied treatment plans have been made. This comparison involves evaluating the different methodologies with identical patients, using identical imaging, critical structures, and target volumes....
