Cancer rates vary between people, between cultures, and between tissue types, driven by clinically relevant distinctions in the risk factors that lead to different cancer types. Despite the importance of cancer location in human health, little is known about tissue-specific cancers in non-human animals. We can gain significant insight into how evolutionary history has shaped mechanisms of cancer suppression by examining how life history traits impact cancer susceptibility across species. Here, we perform multi-level analysis to test how species-level life history strategies are associated with differences in neoplasia prevalence, and apply this to mammary neoplasia within mammals. We propose that the same patterns of cancer prevalence that have been reported across species will be maintained at the tissue-specific level. We used a combination of factor analysis and phylogenetic regression on 13 life history traits across 90 mammalian species to determine the correlation between a life history trait and how it relates to mammary neoplasia prevalence. The factor analysis presented ways to calculate quantifiable underlying factors that contribute to covariance of entangled life history variables. A greater risk of mammary neoplasia was found to be correlated most significantly with shorter gestation length. With this analysis, a framework is provided for how different life history modalities can influence cancer vulnerability. Additionally, statistical methods developed for this project present a framework for future comparative oncology studies and have the potential for many diverse applications.

The goal of this project was to design and create a genetic construct that would allow for <br/>tumor growth to be induced in the center of the wing imaginal disc of Drosophila larvae, the <br/>R85E08 domain, using a heat shock. The resulting transgene would be combined with other <br/>transgenes in a single fly that would allow for simultaneous expression of the oncogene and, in <br/>the surrounding cells, other genes of interest. This system would help establish Drosophila as a <br/>more versatile and reliable model organism for cancer research. Furthermore, pilot studies were <br/>performed, using elements of the final proposed system, to determine if tumor growth is possible <br/>in the center of the disc, which oncogene produces the best results, and if oncogene expression <br/>induced later in development causes tumor growth. Three different candidate genes were <br/>investigated: RasV12, PvrACT, and Avli.

This paper aims to investigate how the portrayal of the crusaders in twentieth and twenty-first century film has evolved and how they have become tools in serving contemporary goals, including those of individual filmmakers and broad societal ideologies. Through the analysis of five films, in both narrative and cinematography, spanning from the 1950s until 2011, themes of redemption, maturity, and the dichotomy of "good" and "bad" are discussed, as well as their chronological evolution in regards to the crusading hero. These films, widely ranging in historical subject matter and country of origin, show a greater range of evolution for the holy war hero and the important themes widely associated with them.

The depiction of mental illness, schizophrenia in particular, within film is a unique phenomenon that film directors have decided to undertake more so in the last 20 years than ever before in cinematic history (Wedding & Niemic, 2014; Robinson, 2004; Gabbard & Gabbard, 1999; Wahl, 1997).

The depiction of mental illness, schizophrenia in particular, within film is a unique phenomenon that film directors have decided to undertake more so in the last 20 years than ever before in cinematic history (Wedding & Niemic, 2014; Robinson, 2004; Gabbard & Gabbard, 1999; Wahl, 1997). Countless filmmakers have taken on the challenge of depicting this complex, yet degenerative condition that entails auditory and visual hallucinations, disorganized thought and speech, and delusions. Its portrayals are usually exaggerated and romanticized, and convey a sense of separate "Otherness" with those who have a mental disorder. And while filmmakers try to encapsulate the schizophrenic experience, it is not without psychiatric error and regarding the person who has schizophrenia as a spectacle. This unfair and ostracizing view of people who have schizophrenia is fueled by films like A Beautiful Mind and The Shining where the film either creates impossibly high standards for schizophrenics to perform at, or the film paints the character as a violent savage. In either case, the end result is the marking and, usually, denouncement of the schizophrenic for their illness. What filmmakers tend to overlook is how much the public learns from the cinematic portrayals of these disorders, and that their films are contributing to an overarching issue of public presumptions of actual schizophrenia and how it is perceived. While the Hollywood approach offers a depiction that is usually more tangible and enjoyable for masses of audiences, spectators should recognize that these are artistic interpretations that take liberties in their depictions of schizophrenia. Viewing these films with an objective mindset to better understand the inner workings of schizophrenia is absolutely crucial in arriving anything close to the truth behind this mental illness that has been demonized long enough.

Popular culture has a longstanding tendency for being affected by, and reversely affecting, politics. Films, in particular, can exist as either purse “escapism” or heady pathways for political commentary. During the Second World War, governments in both the United States and Great Britain used film as a vessel for their own messages, but after the war ended, the two nations allowed their respective film industries more free expression in commenting on wartime and post-war politics. Film also provided particularly vivid political commentary during, and in the years immediately following, the Cold War. Though film has a longstanding history of being a force for political commentary, the medium’s specific engagement with the Cold War holds particular significance because works produced by the two nations’ film industries paralleled the social trend toward political activism at the time. While films produced in the UK and the United States in the 1960s addressed a wide range of contentious political issues, a huge body of work was spurred on by one of the most pressing political tensions of the time: namely, the Cold War.

The United States and Great Britain were major, allied forces during the Cold War. Despite their allied positions, they had unique politico-social perspectives that greatly reflected their immediate involvement in the conflict, in addition to their respective political histories and engagement in previous wars. As the Cold War threat was a large and, in many ways, incomprehensible one, each country took certain elements of the Cold War situation and used those elements to reflect their varied political social positions to a more popular audience and the culture it consumed.

In turn, filmmakers in both countries used their mediums to make overarching political commentaries on the Cold War situation. This analysis looks at five films from those countries during the 1960s, and explores how each representation offered different, often conflicting, perspectives on how to “manage” Cold War tensions, while simultaneously reflecting their conflicted culture and political decisions. The films analyzed reveal that each country focused on contrasting perceptions about the source of the threat posed by Soviet forces, thus becoming tools to further promote their distinct political stances. While the specifics of that commentary changed with each filmmaker, they generally paralleled each country’s perspective on the overall Cold War atmosphere. The British message represented the Cold War as a very internal battle—one that involved the threat within UK borders via the infiltration of spies the tools of espionage. In contrast, the American films suggest that the Cold War threat was largely an internal one, a struggle best combatted by increasing weaponry that would help control the threat before it reached American borders.

Current studies in Multiple Myeloma suggest that patient tumors and cell lines cluster separately based on gene expression profiles. Hyperdiploid patients are also extremely underrepresented in established human myeloma cell lines (HMCLs). This suggests that the average HMCL model system does not accurately represent the average myeloma patient. To investigate this question we performed a combined CNA and SNV evolutionary comparison between four myeloma tumors and their established HMCLs (JMW-1, VP-6, KAS-6/1-KAS-6/2 and KP-6). We identified copy number changes shared between the tumors and their cell lines (mean of 74 events - 59%), those unique to patients (mean of 21.25 events - 17%), and those only in the cell lines (mean of 30.75 events \u2014 24%). A relapse sample from the JMW-1 patient showed 58% similarity to the primary diagnostic tumor. These data suggest that, on the level of copy number abnormalities, HMCLs show equal levels of evolutionary divergence as that observed within patients. By exome sequencing, patient tumors were 71% similar to their representative HMCLs, with ~12.5% and ~16.5% of SNVs unique to the tumors and HMCLs respectively. The HMCLs studied appear highly representative of the patient from which they were derived, with most differences associated with an enrichment of sub-populations present in the primary tumor. Additionally, our analysis of the KP-6 aCGH data showed that the patient's hyperdiploid karyotype was maintained in its respective HMCL. This discovery confirms the establishment and validation of a novel and potentially clinically relevant hyperdiploid HMCL that could provide a major advance in our ability to understand the pathogenesis and progression of this prominent patient population.

Adaptive therapy utilizes competitive interactions between resistant and sensitive cells by keeping some sensitive cells to control tumor burden with the aim of increasing overall survival and time to progression. The use of adaptive therapy to treat breast cancer, ovarian cancer, and pancreatic cancer in preclinical models has shown significant results in controlling tumor growth. The purpose of this thesis is to draft a protocol to study adaptive therapy in a preclinical model of breast cancer on MCF7, estrogen receptor-positive, cells that have evolved resistance to fulvestrant and palbociclib (MCF7 R). In this study, we used two protocols: drug dose adjustment and intermittent therapy. The MCF7 R cell lines were injected into the mammary fat pads of 11-month-old NOD/SCID gamma (NSG) mice (18 mice) which were then treated with gemcitabine.<br/>The results of this experiment did not provide complete information because of the short-term treatments. In addition, we saw an increase in the tumor size of a few of the treated mice, which could be due to the metabolism of the drug at that age, or because of the difference in injection times. Therefore, these adaptive therapy protocols on hormone-refractory breast cancer cell lines will be repeated on young, 6-week old mice by injecting the cell lines at the same time for all mice, which helps the results to be more consistent and accurate.

There exists a gendered difference in how sports films portray female protagonist athletes. This creative project closely examines scenes from four films, Bend It Like Beckham, Million Dollar Baby, Girlfight and Whip It, that collectively represent four gendered themes that are present within the female protagonist sport film subgenre. Each film provides representative examples for themes of exceptionalism, the explicit presence of gender or sexuality, paternal or romantic relationships with male characters, and the punishment or containment of the female athlete. These themes are then analyzed for their presence and meaning in the film genre, including how existing heteronormative film structures are present in female protagonist sport films and how such ideas are reflections of wider societal values. This exposes how the continued use of such heteronormative themes perpetuates stereotypes of female athleticism. After understanding how these themes take shape and what they mean for the genre, this paper then highlights examples of an emergent more feminist genre, promotes alternative filmmaking methods and progressive change to the portrayal of female athletes in sport film.

Cancer is a disease that occurs in many and perhaps all multicellular organisms. Current research is looking at how different life history characteristics among species could influence cancer rates. Because somatic maintenance is an important component of a species' life history, we hypothesize the same ecological forces shaping the life history of a species should also determine its cancer susceptibility. By looking at varying life histories, potential evolutionary trends could be used to explain differing cancer rates. Life history theory could be an important framework for understanding cancer vulnerabilities with different trade-offs between life history traits and cancer defenses. Birds have diverse life history strategies that could explain differences in cancer suppression. Peto's paradox is the observation that cancer rates do not typically increase with body size and longevity despite an increased number of cell divisions over the animal's lifetime that ought to be carcinogenic. Here we show how Peto’s paradox is negatively correlated for cancer within the clade, Aves. That is, larger, long-lived birds get more cancer than smaller, short-lived birds (p=0.0001; r2= 0.024). Sexual dimorphism in both plumage color and size differ among Aves species. We hypothesized that this could lead to a difference in cancer rates due to the amount of time and energy sexual dimorphism takes away from somatic maintenance. We tested for an association between a variety of life history traits and cancer, including reproductive potential, growth rate, incubation, mating systems, and sexual dimorphism in both color and size. We found male birds get less cancer than female birds (9.8% vs. 11.1%, p=0.0058).

Horror films are typically comprised of three specific features: jump scares, gore, and suspense shots of a shadowy figure creeping up on an unaware victim. These three elements are some of the hallmarks of what defines the horror genre as they are methods that have proven successful in eliciting a bodily response within audience members, which is crucial to a horror movie being considered successful. However, these elements are also very polarizing. Individuals that enjoy horror often like these three things, while those who don’t appreciate the genre often cite over the top gore, distain for jump scares, and the anxiety that accompanies those suspenseful shots as primary reasons for avoiding horror. Due to the fact that those spectators who like horror tend to be in the minority, horror tends to have a very weak crossover appeal, thus limiting the audience interest while also being very unpopular among critics as well.
Interestingly, three recent horror films have achieved both critical acclaim and popularity among all audiences, horror and non-horror fans alike. Get Out, A Quiet Place, and It Follows are all noticeably lacking in the three features that commonly make a horror film “successful”, and yet it would be difficult to argue that they aren't successful horror films given that they have received critical acclaim, impressive box office returns, and have a strong crossover appeal. Therefore, they must use alternative methods to achieve the bodily response of fear that is necessary to be successful in the genre. I argue that these films put the audience member in a position that mirrors what Forced Lacanian Hysteric Neurosis and that this positioning produces the bodily response that is necessary for a horror movie to be successful. This manifestation has the additional benefit of allowing those spectators who do not like the fundamental aspects of horror (jump scares, gore, and suspenseful shots) to find the pleasure of horror without experiencing on-screen events that might cause them notable distress.
