Exceptional Driving Principles For Autonomous Vehicles, A. D'Amato, S. Dancel, J. Pilutti, L. Tellis, E. Frascaroli, J. C. Gerdes

Journal of Law and Mobility

Public expectations for automated vehicles span a broad range, from mobility for passengers, to road user safety, to compliance with the traffic code. In most ordinary situations, these expectations can be satisfied simultaneously. But these various expectations can also lead to exceptional scenarios where certain objectives, such as those related to safety, are in tension with road rules. Exceptional driving scenarios challenge motion planning algorithms in automated vehicles to find solutions that are legally grounded, ethically sound, and technically feasible.

The general public’s familiarity with exceptional driving scenarios comes from the classic "Trolley Car" problem in philosophy, asking who should …

Jemimas, Jockeys, And Jolly Banks: The Racial Discourse Of Black Collectibles, Conrad Pruitt

CGU Theses & Dissertations

Over the last thirty years, an industry in black racist memorabilia has resurged. Bolstered by online commerce, social media trade, and a robust reproduction market, racist collectibles continue to circulate despite their functional obsolescence or presumed incongruity with current views of race. Many of these objects originated in the late nineteenth century, where the emergence of black citizenship was seen as a threat to a racial caste structure that ensured white supremacy. Following the impetus for supremacy that defined the Jim Crow era, the collectibles sought to crystallize conceptions of inherent black inferiority. The presumption that these originary conditions and …

This dissertation provides a sustained theoretical articulation of core Lacanian psychoanalytic concepts situated within the standing difficulties in the practice and theory of museums. Drawing upon research gathered from site visits, informational interviews, textual analysis, and an extensive engagement with the seminars of Jacques Lacan, I enumerate here a first attempt at what a Lacanian theoretical formation can contribute to museum studies scholarship. Through this research this dissertation shows psychoanalysis to be especially useful for museum studies owing to how the troubles immediately encountered in the everyday material practices of museological work are structurally analogous to the impossibilities experienced on …

An Exploratory Analysis Of How Maya Angelou, Audre Lorde, And Patrisse Cullors Radicalized The Meaning And Practice Of Self-Care, Melanie Marie Lindsay

CGU Theses & Dissertations

My dissertation, “An Exploratory Analysis of How Maya Angelou, Audre Lorde, and Patrisse Cullors Radicalized the Meaning and Practice of Self-Care”, hypothesizes that we can conceive a practice of self-care using an abolitionist lens to examine the writings and performances of three Black feminists Maya Angelou, Audre Lorde, and Patrisse Cullors. Abolitionist self-care is a response to the political structures that directly affect marginalized communities, and it evaluates the numerous ways that Black women have used their voice to challenge systems of oppression. If we examine their thinking as expressed through their poetry, their performances (including activism), and their self-life-writing, …

The Nutritional Condition Of Moose Co-Varies With Climate, But Not With Density, Predation Risk, Or Diet Composition, Jennifer S. Forbey, Daniel P. Melody

Biology Faculty Publications and Presentations

A fundamental question about the ecology of herbivore populations pertains to the relative influence of biotic and abiotic processes on nutritional condition. Nutritional condition is influenced in important, yet poorly understood, ways by plant secondary metabolites (PSMs) which can adversely affect a herbivore’s physiology and energetics. Here we assess the relative influence of various abiotic (weather) and biotic (intraspecific competition, predation risk and diet composition) factors on indicators of nutritional condition and the energetic costs of detoxifying PSMs for the moose population in Isle Royale National Park (U.S.A.). Specifically, we observed interannual variation in the ratio of urea nitrogen to …

Sex Differences In Cognitive Flexibility Are Driven By The Estrous Cycle And Stress-Dependent, Andrew T. Gargiulo, Jiayin Hu, Isabella C. Ravaglia, Annie Hawks, Xinyue Li, Katherine Sweasy, Laura A. Grafe

Psychology Faculty Research and Scholarship

Stress is associated with psychiatric disorders such as post-traumatic stress disorder, major depressive disorder, anxiety disorders, and panic disorders. Women are more likely to be diagnosed with these stress-related psychiatric disorders than men. A key phenotype in stress-related psychiatric disorders is impairment in cognitive flexibility, which is the ability to develop new strategies to respond to different patterns in the environment. Because gonadal hormones can contribute to sex differences in response to stress, it is important to consider where females are in their cycle when exposed to stress and cognitive flexibility testing. Moreover, identifying neural correlates involved in cognitive flexibility …

Redirected Utopias: The Politics Of Self-Reflexive Autobiographical Documentary In Albertina Carri’S Los Rubios And Ufuk Emiroglu’S Mon Père, La Révolution, Et Moi, Stephanie Pridgeon

All Faculty Scholarship

Twenty-first century documentary production from around the world has used self-reflexivity to challenge assumptions about subjectivity and social positioning in ways that explicitly challenge the politics of filmmaking. Released in 2003 and 2013 respectively, Argentine director Albertina Carri’s Los rubios and Turkish filmmaker Ufuk Emiroglu’s Mon père, la révolution et moi incorporate fictions and fantasies into their autobiographical stories, telling their life stories through alternative narrative forms that deviate from existing social and aesthetic precepts. The two filmmakers seek to understand–and scrutinize–the utopian ideals of the revolutionary movements to which their fathers belonged in 1970s Argentina and Turkey, respectively. The …

Animating Potential For Intensities And Becoming In Writing: Challenging Discursively Constructed Structures And Writing Conventions In Academia Through The Use Of Storying And Other Post Qualitative Inquiries, Mary Catherine Garland

School of Law, Humanities and Social Sciences Theses

Written for everyone ever denied the opportunity of fulfilling their academic potential, this is ‘Chloe’s story’. Using composite selves, a phrase chosen to indicate multiplicities and movement, to story both the initial event leading to ‘Chloe’s’ immediate withdrawal from a Further Education college and an imaginary second chance to support her whilst at university, this Deleuzo-Guattarian (2015a) ‘assemblage’ of post qualitative inquiries offers challenge to discursively constructed structures and writing conventions in academia. Adopting a posthuman approach to theorising to shift attention towards affects and intensities always relationally in action in multiple ‘assemblages’, these inquiries aim to decentre individual ‘lecturer’ …

Deoxyribose Phosphate Aldolase Is Required For Development Of Hematopoietic Stem Cells In The Zebrafish Embryo, Anubhav Thapaliya, Sanyam Patel, Teerth Y. Patel, Sivam J. Bhatt, Erich W. Damm

UROP Posters

Hematopoietic stem cells (HSCs) are an integral part of modern biomedical research because they are precursors to all blood cell lineages in vertebrates. Further understanding of hematopoietic development will allow for improvements in the success of therapeutic bone marrow transplantation; which is a crucial treatment in management of both malignant and non-malignant blood disorders. Although HSC transplantation is curative for many blood disorders, finding compatible donors is difficult due to a need for immunologic compatibility. Consequently, recent research efforts have been directed towards generating HSCs for the patient, from the patient themselves through the directed differentiation of induced pluripotent stem …

Chemical Biology Of Dna Adduct Repair, Bypass And Mutagenesis, Rui Qi

Open Access Dissertations

DNA is necessarily to be stable and intact since it is the repository of genetic information in each living cell. However, DNA is not inert, and it is vulnerable to the endogenous and environmental assault including reactive oxygen species (ROS), ultraviolet (UV) light, and various carcinogens. Exposure to these DNA damaging agents is associated with various adducts ranging from small methyl or etheno adducts to bulky adducts such as acetylaminofluorene. These resulting damages, if not repaired, will lead to replication block or mutation which can eventually cause cancer or other genetic diseases. The research covered by this dissertation falls into …

Acoustic And Optical Imaging Techniques For Characterizing Animal Distributions In The Pelagic Ocean, Benjamin Grassian

Open Access Dissertations

Biological processes in midwater habitats -- ocean areas between the sunlit surface layers and sea floor -- are critical drivers of ocean biogeochemical cycling, oxygen availability, fish population dynamics, and ecological interactions over a wide range of scales. Achieving high-resolution observations of the environmental and biological heterogeneity in the ocean's interior is important for understanding the status and evolution of the earth system at large. Traditional ocean sampling platforms (e.g. net systems, moored and shipboard sensors), are often unable to resolve marine biota at fine (cm-m) scales and over submesoscale (sub-km to kms) survey areas comparable to the relevant variability …

The American Lobster (Homarus Americanus) In Narragansett Bay During A Time Of Ecosystem Flux: Temperature, Predation, And Larval Dynamics, Kristin Huizenga

Open Access Dissertations

The American lobster (Homarus americanus) in southern New England sustained a particularly prosperous fishery during the 1980s and 1990s. However, in 2001 lobsters in the region began to decline, leading to the eventual collapse of the fishery in Rhode Island. The Narragansett Bay was no exception to this trend, with the number of lobsters caught by the University of Rhode Island Graduate School of Oceanography weekly fish trawl survey peaking in the 1990s before the decline. Today, few lobsters are caught in the Bay.

This dissertation seeks to identify whether environmental stressors and predators drive lobster populations in …

Similitude, Scaling, And Prediction Of Stream Dissolved Oxygen Across The Contiguous U.S., Aron Gebreslase

Graduate Theses, Dissertations, and Problem Reports (ETD)

Dissolved oxygen (DO) is a general indicator of stream water quality and ecosystem health. However, the concentration of in-stream DO is controlled by various climatic, land use/cover, hydrologic, biochemical, and ecological drivers. Observational data for stream DO are often unavailable at the desired temporal and spatial scales. Accurate and reliable prediction of stream DO concentration based on a small set of environmental drivers is important to guide the water managers and policymakers to achieve and maintain healthy streams. This dissertation focused on identifying the dominant controls of stream DO and understanding the mechanisms and environmental regimes by employing machine learning, …
