Empathy And Community In The Age Of Refugees: Petzold’S Radical Translation Of Seghers’ Transit, Margarete Landwehr

Languages & Cultures Faculty Publications

Petzold’s film constitutes a radical translation of Seghers’ novel by transforming her tale of political refugees in Vichy France into an existential allegory depicting the fluidity of identities and relationships in a globalized world. The transitory existence of Petzold’s war refugee serves as an extreme example of the instability of modern life, which allows spectators to identify and empathize with migrants’ unpredictable journeys. Moreover, the director conveys the universality of his protagonist’s story by portraying him as an Everyman bereft of distinctive personality traits, by intermingling the past (Seghers’ plot) with the present (contemporary settings), and by situating his experiences …

Paid Family Leave & The Media: A Narrative Policy Framework, Nichole Angelic Horn

Public Affairs Dissertations - Archive

This study seeks to understand how paid family leave laws influence traditional gender roles and stereotypes. The mother homemaker/father breadwinner narrative, a prominent concept within feminist circles, assumes particular gendered roles that include women’s responsibility for unpaid labor within the home. The implications of these gendered roles leave women in an economically disadvantaged position. Given the media’s influence in policy making and function to echo current social values, this study utilizes the Narrative Policy Framework (NPF) to investigate how the media frames these policies, and whether that framing helps to dismantle traditional gender narratives. This study finds that as these …

Public schools continue to look to become more efficient and strategic in the allocation of their available resources for promoting academically focused and successful students. The value of programs that are not directly connected to the standardized testing system currently in place, such as arts education, are often overlooked when school districts make their financial decisions. This is problematic because the benefits afforded to students through the …

Copyright's Fixation Requirement: Is It Still Needed?, Attamongkol Tantratian

Maurer Theses and Dissertations

While the United States requires fixation for an original work to be entitled to federal copyright protection, many other countries ignore such requirement. The difference could lead to partial copyright protection standards across jurisdictions over certain works that are not fixed. Examples of such works include extemporaneous speeches, lectures, improvisational performances, and contemporary arts that are transitory. Moreover, with today’s rapid development of arts and technologies, creative works can be presented via new media without being fixed in a traditional way. The examples include live streams of lectures and music performances, which have become part of the “new normal.” In …

Who Dreams Of Badges? Gendered Self-Concept And Policing Career Aspirations, Samantha S. Clinkinbeard, Starr J. Solomon, Rachael M. Rief

Criminology and Criminal Justice Faculty Publications

NIJ’s Policing Research Plan (2017-2022) highlights the need to understand factors that attract diverse candidates. We explored whether college students had ever considered policing and found men were significantly more likely than women to contemplate policing careers. Further, we found higher levels of masculinity were associated with greater odds of policing aspirations; the relationship between gender and aspirations was fully mediated by masculine self-concept. Although men typically reported higher masculinity scores, within-gender analyses indicated that masculinity was important for both men and women. Our findings suggest the continued association of masculinity with policing may undercut efforts to recruit a representative …

Development Of Extracellular Vesicle Isolation And Model Systems Toward Early Ovarian Cancer Diagnostics, Tyler Slonecki

All Dissertations

Ovarian cancer (OC) is characterized by late stage discovery and low survivability. However, when diagnosed early (Stages I or II) the 5-year survival rate is 92% up from 29%.5 The extreme dichotomy in survivability is what makes OC a prime candidate for early diagnosis techniques. Exosomes, a subtype of extracellular vesicles, may bridge the gap between early and late diagnosis, but are lacking consistent isolation and detection technologies. Here poly(ethylene terephthalate) (PET) capillary channeled polymer (C-CP) fibers employing an HIC protocol are investigated as a novel exosome isolation method and a quick, inexpensive, and easy-to-use platform for OC diagnosis. The …

Fantasy And Realism In Contemporary Ecuadorian Literature (1976-2006), Kimberly E. Contag

MSU Authors Collection

My purpose in this book is not to assess how well Ecuadorian literature fits into the broad Latin American literary scene or the global scene in particular, but instead to read and analyze how Ecuadorian writers communicate ideas about the world they live in through realism and fantasy. It is the nature of Ecuadorians to express their experience in these terms to portray a unique and multifaceted voice. To that end, I propose a model for analyzing the function of fantasy and realism in literature, principally in the novel, short story, flash fiction, poetry, flash poetry, and theater, and offer …

Comparative Evaluation Of Statistical Dependence Measures, Eman Abdel Rahman Ibrahim

Graduate Theses and Dissertations

Measuring and testing dependence between random variables is of great importance in many scientific fields. In the case of linearly correlated variables, Pearson’s correlation coefficient is a commonly used measure of the correlation strength. In the case of nonlinear correlation, several innovative measures have been proposed, such as distance-based correlation, rank-based correlations, and information theory-based correlation. This thesis focuses on the statistical comparison of several important correlations, including Spearman’s correlation, mutual information, maximal information coefficient, biweight midcorrelation, distance correlation, and copula correlation, under various simulation settings such as correlative patterns and the level of random noise.

Faculty Publications

The msaABCR operon regulates several staphylococcal phenotypes such as biofilm formation, capsule production, protease production, pigmentation, antibiotic resistance, and persister cells formation. The msaABCR operon is required for maintaining the cell wall integrity via affecting peptidoglycan cross-linking. The msaABCR operon also plays a role in oxidative stress defense mechanism, which is required to facilitate persistent and recurrent staphylococcal infections. Staphylococcus aureus is the most frequent cause of chronic implant-associated osteomyelitis (OM). The CA-MRSA USA300 strains are predominant in the United States and cause severe infections, including bone and joint infections.

Associative Nitrogen Fixation Linked With Three Perennial Bioenergy Grasses In Field And Greenhouse Experiments, Jayani J. Wewalwela, Yuan Tian, Janet R. Donaldson, Brian S. Baldwin, Jac J. Varco, Brett Rushing, Haoliang Lu, Mark A. Williams

An Efficient 3-D Stochastic Hie-Fdtd Algorithm For Investigation Of Statistical Variation In Electromagnetic Field, Kaikun Niu, Zhixiang Huang, Xingang Ren, Ke Xu, Minquan Li, Xianliang Wu, Ping Li, Lijun Jiang, Hakan Bagci

Electrical and Computer Engineering Faculty Research & Creative Works

We propose a stochastic hybrid implicit-explicit finite-difference time-domain method (S-HIE-FDTD) to compute the mean and variance of the electromagnetic (EM) fields using a single simulation, given those of the conductivity and permittivity in the computation domain. The mean and variance field update equations underlying the proposed method are derived from the field update equations of the 'traditional' deterministic HIE-FDTD. The Courant-Friedrichs-Lewy condition of the S-HIE-FDTD depends on the spatial discretization sizes only in two dimensions; therefore, for computation domains with fine geometric features only in the remaining dimension, it uses a time step size that is larger than that of …

Show Me The (Data About The) Money!, Nizan Geslevich Packin

Utah Law Review

Information about consumers, their money, and what they do with it is the lifeblood of the flourishing financial technology (“FinTech”) sector. Historically, highly regulated banks jealously protected this data. However, consumers themselves now share their data with businesses more than ever before. These businesses monetize and use the data for countless prospects, often without the consumers’ actual consent. Understanding the dimensions of this recent phenomenon, more and more consumer groups, scholars, and lawmakers have started advocating for consumers to have the ability to control their data as a modern imperative. This ability is tightly linked to the concept of open …

Incidence Of Antibiotic Resistance And Plasmid Content In Freshwater Beach Sand And Water And Clinical Urinary Tract Infection Escherichia Coli Isolates, Robert F. White

Biology Theses

Antibiotic-resistant (AR) bacteria have been found in environmental ecosystems including beach sand and water, and pose a serious threat to the mitigation of human and animal disease. The presence of antibiotic residues in the environment, fueled by wastewater effluent and agricultural runoff, may produce selective pressure on introduced microbes such as Escherichia coli, leading to the production of AR populations. This study characterized and compared the antibiotic resistance patterns and plasmid content of E. coli isolated from a freshwater beach and clinical urinary tract infection (UTI) samples. A higher level of antibiotic resistance was expected in clinical (UTI) Escherichia coli …
