Sexy Robots: A Perpetuation Of Patriarchy, Ashlyn Des Roches

Communication Studies

This feminist critique looks into the way that gender, specifically females, are portrayed in some of Hollywood's top films involving Artificial Intelligence: Blade Runner, Her, and Ex Machina. These movies work as a perpetuation of patriarchal ideologies while maintaining the objectification and hypersexuality of women as normalized behaviors. Additionally, while some forms of empowerment are conveyed, the features illustrate women merely on a spectrum of extreme behavior; due to Heuristics and Cultivation Theory, these misrepresentations can be associated with women outside the surrealist realm of the depicted artificially intelligent worlds.

The Insulin-Like Growth Factor-1 (Igf1) System As A Potential Biomarker For Nutritional Status And Growth Rate In Pacific Rockfish (Sebastes Spp.), Nicole L. Hack

Master's Theses

Growth performance in vertebrates is regulated by environmental factors including the quality and quantity of food, which influences growth via endocrine pathways such as the growth hormone (GH) / insulin-like growth factor somatotropic axis. In several teleost fishes, circulating concentrations of insulin-like growth factor-1 (Igf1) correlate positively with growth rate, and it has been proposed that plasma Igf1 levels may serve as an indicator of growth variation for fisheries and aquaculture applications. Here, I tested whether plasma Igf1 concentrations might serve as an indicator of somatic growth in olive rockfish (Sebastes serranoides), one species among dozens of rockfishes …

Developmental Trajectories Of Bottle-Feeding During Infancy And Their Association With Weight Gain, Alison K. Ventura

Kinesiology and Public Health

Objective: To describe patterns of bottle-feeding across the first year postpartum and explore whether bottle-feeding trajectories are differentially associated with infant weight gain.

Method: Data came from 1291 mothers who participated in the Infant Feeding Practices Study 2. Mothers completed a prenatal questionnaire and monthly surveys of infant feeding and growth between birth and 12 months. Group-based trajectory mixture modeling was used to describe developmental trajectories of bottle-feeding intensities across the first year. Growth curve modeling was used to explore associations between bottle-feeding intensity trajectory group membership and weight-for-age z-score (WAZ) trajectories from birth to 12 months.

Results: Four qualitatively …

Drivers Of Redistribution Of Fishing And Non-Fishing Effort After The Implementation Of A Marine Protected Area Network, Reniel B. Cabral, Steven D. Gaines, Brett A. Johnson, Tom W. Bell, Crow White

Biological Sciences

Marine spatial planning (MSP) is increasingly utilized to sustainably manage ocean uses. Marine protected areas (MPAs), a form of spatial management in which parts of the ocean are regulated to fishing, are now a common tool in MSP for conserving marine biodiversity and managing fisheries. However, the use of MPAs in MSP often neglects, or simplifies, the redistribution of fishing and non-fishing activities inside and outside of MPAs following their implementation. This redistribution of effort can have important implications for effective MSP. Using long-term (14 yr) aerial surveys of boats at the California Channel Islands, we examined the spatial redistribution …

The Proteomic Responses Of Gill Tissue In Tidally And Subtidally-Acclimated Mussel Congeners (Mytilus Trossulus And Mytilus Galloprovincialis) To Acute Aerial-Emersion Hypoxia, Jaclyn Denise Campbell

Master's Theses

Understanding species-specific physiological tolerances to environmental extremes is key in determining the factors that contribute to regulating species distribution. This understanding will aid in determining which species will manage to thrive in a changing global climate. According to the IPCC (2013) it is expected that, in the coming years, many different types of abiotic factors will change as a result of global climate change. The intertidal habitat is a model habitat for studying environmental extremes as it is located at the interface between the marine and terrestrial environments, making it one of the most stressful marine habitats. It is characterized …

Plant Compound Pest Control In California Strawberry (Fragaria × Ananassa) Production, Eli Mahanes Weissman

Master's Theses

Allelopathy occurs when one organism releases a compound into the environment that affects the functioning of another organism. Scientists have long suspected that alleopathic plant compounds could offer novel, softer chemistries to the ongoing battle of controlling pests in agricultural fields. Strawberry growers rely on toxic fumigants to kill soilborne fungal pests, weeds, nematodes, and insects. Increased regulations have reduced the use of fumigants (including methyl bromide), and strawberry growers need new sustainable pest control solutions. We selected four putative allelochemicals with known fungicidal and herbicidal activity (ferulic acid, gallic acid, juglone, and p-Coumaric acid). We assessed the pesticidal activity …

What Is ... Benford’S Law?, Arno Berger, Theodore P. Hill

Research Scholars in Residence

Benford’s law quantifies the surprising fact that in many datasets, such as populations of counties, numbers on the World Wide Web, or incomes and expenses on tax returns, the numbers are much more likely to start with small digits like 1 or 2 than with large digits like 8 or 9. The law actually provides a specific probability distribution on the (significant) digits, telling exactly how likely each sequence of digits is.

The Effect Of Biocomposite Material In A Composite Structure Under Compression Loading, Benjamin Andrew Sweeney

Master's Theses

While composite structures exhibit exceptional strength and weight saving possibilities for engineering applications, sometimes their overall cost and/or material performance can limit their usage when compared to conventional structural materials. Meanwhile ‘biocomposites’, composite structures consisting of natural fibers (i.e. bamboo fibers), display higher cost efficiency and unique structural benefits such as ‘sustainability’. This analysis will determine if the integration of these two different types of composites are beneficial to the overall structure. Specifically, the structure will consist of a one internal bamboo veneer biocomposite ply; and two external carbon fiber weave composite plies surrounding the bamboo biocomposite. To acquire results …

An Assessment Of Potential False Positive E.Coli Pyroprints In The Cplop Database, Skyler A. Gordon

Master's Theses

The genetic information found in each species of organism is unique, and can be used as a tool to differentiate at the molecular level. This has caused rapid genotyping methods to become the cornerstone of a new area of research dependent on reading the genome as a form of identification. One of these specific identification methods, known as pyroprinting, relies on the small variation of DNA sequences within the same species to develop a unique, reproducible fingerprint. By simultaneously pyrosequencing multiple polymorphic loci within the ribosomal operons known as the intergenic transcribed spacers, a reproducible output is obtained, known as …

Local Diurnal Wind‐Driven Variability And Upwelling In A Small Coastal Embayment, Ryan K. Walter, Emma C. Reid, Kristen A. Davis, Kevin Armenta, Kevin Merhoff, Nicholas J. Nidzieko

Physics

The oceanic response to high‐frequency local diurnal wind forcing is examined in a small coastal embayment located along an understudied stretch of the central California coast. We show that local diurnal wind forcing is the dominant control on nearshore temperature variability and circulation patterns. A complex empirical orthogonal function (CEOF) analysis of velocities in San Luis Obispo Bay reveals that the first‐mode CEOF amplitude time series, which accounts for 47.9% of the variance, is significantly coherent with the local wind signal at the diurnal frequency and aligns with periods of weak and strong wind forcing. The diurnal evolution of the …

Singer, Wittgenstein, And Morally Motivating Examples, Ramona Ilea

Between the Species

Peter Singer’s Animal Liberation played a pivotal role in the animal rights movement and the foundation of modern animal ethics. Using an analysis inspired by Wittgenstein’s remarks on ethics, I will analyze the way in which Singer’s book is structured in order to understand why it succeeds in providing people with the moral motivation to change the way they live. I will argue that the success of Animal Liberation is in large part due to the detailed, carefully chosen, emotionally rich examples and the unusual way in which these examples are juxtaposed, structured, and presented. Understanding how examples can have …

Araucaria In The Urban Landscape: A Novel Leaning Pattern And Evidence Of Cultivated Hybridization, Jason W. Johns

Master's Theses

Our understanding of the natural world is constantly evolving and strengthening as more observations are made and experiments are performed. For example, we understand that tree stems grow toward the light (positive phototropism; Darwin 1880, Loehle 1986, Christie et al. 2013) and against gravity (negative gravitropism; Knight 1806, Hashiguchi et al. 2013). We also know that plants respond to mechanical stimulus and perturbation (thigmotropism; Braam 2005). Genes and their resulting proteins have been described to uncover some of the mechanisms for these environmental responses, but relatively speaking, we have just scratched the surface (Wyatt et al. 2013). While the discovery …
