All That Is Cyber Melts Into Control: A Rhetorical Analysis Of Cybernetic Metaphors, Cem İsmail Addemir

Theses and Dissertations

This thesis historicizes and interprets the logic of cybernetics as a communication technology and how it shaped notions of control in the mid-20th century. To situate my analysis, I focus on cybernetics, the tradition within communication studies that focuses on controlling communication through the application of feedback loops to a particular system. Since the discovery and popularization of cybernetics by the late 1950s, its central logic has been widely applied to computational technology and influenced future systems theories. Specifically, my thesis employs a rhetorical examination of cybernetic metaphors through metaphor criticism to trace the genealogy of cybernetic discourses that I …

Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell

Theses and Dissertations

This thesis explores how Nobel laureate Olga Tokarczuk's 2008 novel, Drive Your Plow Over the Bones of the Dead, engages with William Blake's life and his writings on animal welfare and speaks to current conversations about multispecies justice in the environmental humanities. It argues, first, that in recognizing how this novel's protagonist, Janina, selectively reads Blake to rationalize retributive justice, readers should resist a tendency to mistake this character for Tokarczuk's ideal advocate for environmental ethics. Secondly, it asserts that legal scholars' division between retributive and restorative justice offers valuable framework for approaching both this novel and ongoing debates about …

Non-Tuberculous Mycobacterium Correlation With Geochemical Characteristics Of Soil And Basalt In Hawaii, Leeza Marie Wells

Theses and Dissertations

Non-tuberculous mycobacteria (NTM) cause opportunistic lung disease though environmental exposure pathways. Among the United States, Hawaii has a significantly higher infection rate. Preliminary studies have shown certain environmental factors, such as phosphorus and other select soil geochemical characteristics, to be statistically significant to NTM occurrence. However, a model to predict NTM occurrence based on soil geochemistry had yet to be attempted. A selection of 40 NTM positive and 40 NTM negative soils from Oahu were selected for a geochemical analysis to search for possible correlations to mineralogy and elemental abundances that may promote, or inhibit, NTM growth in the environment. …

Projecting The Effects Of Climate Change And Urbanization On Longleaf Pine Stands In The Florida Flatwoods, Lilian Grace Hutchens

Theses and Dissertations

The southeastern United States once held millions of hectares of highly connected longleaf pine ecosystem. In a dramatic range reduction, longleaf pine now occupies less than 5% of its original extent, its remnant patches existing within a matrix of human-dominated land uses. Conservation planning for longleaf pine ecosystems is complicated given the ecosystem’s reliance on fire and the broad spatial and temporal scales at which longleaf pine management must operate. Planning timelines for longleaf pine management extend into the end of the 21st century, a period during which climate, fire regimes, and land cover are all expected to change, influencing …

Genetic Mechanisms Underlying Maladaptation In Specialized Species Interactions, Nitin Ravikanthachari

Theses and Dissertations

Adaptation has been used as the framework to understand the power of natural selection in structuring biodiversity and driving biological interactions. However, recent examples have indicated that many organisms are maladapted to their local conditions. Maladaptation can result from various causes including rapid environmental change, novel environments, interplay of evolutionary forces (viz: gene flow-selection balance) and anthropogenic disturbance.

To dissect the genetic mechanisms underlying maladaptation, I used the interaction between Pieris macdunnoughii (Remington) (Lepidoptera: Pieridae) which lays eggs on an invasive mustard Thlaspi arvense (L.) (Brassicaceae), which is lethal to the larvae.

First, local adaptation to avoid laying eggs on …

Patterns, Mechanisms, And Characterization Of Carbon Cycling Stability Following Partial Forest Disturbance, Kayla C. Mathes

Theses and Dissertations

Among the most essential questions in the era of climate change is how the forest carbon (C) cycle will respond to an increase in the extent of biotic disturbances from insects and pathogens. While research has focused on stand-replacing disturbance regimes, less is known about C cycling stability following partial disturbances that produce gradients of disturbance severity. Belowground C cycling responses to disturbance are especially poorly understood, even though temperate forest soils contain up to 50% of total ecosystem C and soil respiration (R_s) accounts for more than half of temperate forest C loss. Interpreting trends and mechanisms …

Diversity, Phylogenetics And Life Cycles Of Diplostomoidean (Digenea: Diplostomoidea) Of The Upper Midwest, Jakson Martens

Theses and Dissertations

The superfamily Diplostomoidea Poirier, 1886 consists of a diverse, globally distributed group ofparasitic flatworms parasitic as adults in reptiles, birds, mammals, and very rarely, fish. The superfamily Diplostomoidea has a tumultuous history full of genus synonymizations and resurrections. Currently, the superfamily consists of 39 genera parasitizing primarily piscivorous animals as adults to include birds, reptiles, and mammals. This group of parasitic worms remains a highly active area of research and has recently undergone several major systematic changes including the abandonment of a subfamily-based system. Additionally, the influx of data entries in GenBank has lead to confusing nomenclature and misidentifications at …
