Amazon – An Infrastructure Service And Its Challenge To Current Antitrust Law, Lina M. Khan

Faculty Scholarship

This chapter maps out facets of Amazon’s power. In particular, it traces the sources of Amazon’s growth and analyzes the potential effects of its dominance. Doing so enables us to make sense of the company’s business strategy and illuminates anticompetitive aspects of its structure and conduct. This analysis reveals that the current framework in antitrust — specifically its equating competition with “consumer welfare,” typically measured through short- term effects on price and output — fails to capture the architecture of market power in the 21st- century marketplace. In other words, the potential harms to competition posed by Amazon’s dominance are …

Counter-Critical Theory: An Intervention In Contemporary Critical Thought And Practice, Bernard E. Harcourt

Faculty Scholarship

Walter Benjamin and Bertolt Brecht's short-lived project for a critical theory journal, Krise und Kritik, foundered in 1931 on the shoals of positivism. Since then, a series of anti-foundational challenges to traditional critical theory has fragmented the landscape of critical theory and, especially, critical praxis, leaving us disarmed today, in these unprecedented times. This essay offers a way forward by means of what it calls “counter-critical theory”: a critical method that indexes the original impulse of critical theory, but liberates it from its foundation in order to allow for a more open-ended and permanent re-examination of how power circulates …

The Influence Of Quality Of Education On A Regression-Based Method Of Premorbid Estimated Intelligence, Elizabet Santana Marmon-Halm

PCOM Psychology Dissertations

The physical, cognitive, behavioral, and emotional sequelae of brain injury have been shown to exert a substantial negative impact on everyday work-related and social functioning. Accordingly, accurate measurement of any associated cognitive decline is of paramount importance, and clinicians often face the challenge of estimating the patient’s level of intellectual functioning prior to the brain pathology. This study examined the influence of environmental factors, such as education quality on a demographically based formula for estimating premorbid intelligence and focused primarily on an adjusted variable (reading level vs. years of education). The results showed that for the entire sample of the …

1 Hour Ghost Visit, Charles Elizabeth Martin

Theses and Dissertations

1 Hour Ghost Visit is a collection of poems that engages with loss, as well as what can grow in the face of that loss. In “Dancing on My Own,” the poet describes being alone on a dance floor: “when the drop comes I become/a glowstick rain/downpouring fire/sprinkler bursting/with glitter/the corpse I’m/growing towards--/what will bloom in our ribcages will be deadly—” and this hunger for determination, for construction in the face of destruction, grows into a roar by the concluding poem’s call for collective celebration in the face of the end of the world.

The poems collectively sing together; they …

Twisting Reality For A Cause: American Mythology, Early Surrealism, And Audience Empowerment In The Works Of George Lippard, Joseph Samuel Hall

Theses and Dissertations

This article examines Philadelphia writer George Lippard's often-overlooked usage of literary conventions more typical outside of the genre he is most famous for, socialreform city fiction. In particular, the article focuses on Lippard’s vision of an American mythology, proto-surrealistic imagery, and demands for audience response and interaction. Various works are analyzed, most prominently: stories from Washington and His Generals, The Rose of the Wissahikon, Adonai: The Pilgrim of Eternity, and The Killers. The article concludes that Lippard values the artfulness of historical romance over presenting historical fact, recognizing the ability of the romance to instigate a greater collective response in …

The Influence Of Mindful Movement On Elementary Students’ Music Listening Enjoyment And Comprehension, Jean Louise Boiteau

Theses and Dissertations

The purpose of this study was to examine the effects of mindful movement on elementary students’ listening comprehension and enjoyment. Participants (N = 40) were third-grade music students who participated in an ABAB within-subjects research design. During baseline phases, participants listened to one of four musical selections. During treatment phases, participants completed a mindful movement activity while listening to the musical selections. After each baseline or treatment experience, participants rated how much they enjoyed the musical recording, answered a free-response question justifying why they chose that enjoyment rating, and completed a listening comprehension test. Although there was a slight increase …

If This Be Sin: Gladys Bentley And The Performance Of Identity, Moira Mahoney Church

Theses and Dissertations

Known for her improvisational risqué lyrics and tailored white tuxedo, Gladys Bentley was one of the most notorious figures of the 1930s. Situated in the pansy and lesbian craze of the 1920s and 30s, Bentley’s career was part of a broader trend that favored gender-queer performers due to their exotic appeal. Despite being more transgressive than most, Bentley has ultimately faded from society’s collective memory.

Environmental Impacts On Enterococcus In Shem Creek, South Carolina, And Characterization Of Changing Land Use, Maria Elizabeth Zubizarreta

Theses and Dissertations

Zoning and land-use practices have a direct influence on hydrologic systems and can impact water resources. Linkages between change in land uses and degradation of water quality in stream and watershed environments have been well established. Shem Creek, located in Mount Pleasant, SC, has a history of fecal indicator bacteria levels that exceed the Environmental Protection Agency’s recreational water quality standards. With recent coastal population and development trends, proper management and the sustainability of beach and estuary environments are a rising public health concern. The objective of this study is to determine what climatic and water quality parameters are associated …

Linking Microbial Phylogenetic And Functional Gene Diversity To Microbial Mat Ecosystem Function Following Environmental Disturbance, Eva Christine Preisner

Theses and Dissertations

The ability of ecosystems to adapt to environmental perturbations depends on the duration and intensity of change and the overall biological diversity of the system. In this study, a microbial mat ecosystem located on San Salvador Island, the Bahamas was used as a model to examine how environmental disturbance affects microbial community resistance, their protein synthesis potential (PSP), ecosystem function as measured by biogeochemical cycling, community stability, and resilience. This ecosystem experienced a large shift in salinity (230 to 65 g kg-1) during 2011–2012 following the landfall of Hurricane Irene on San Salvador Island. High throughput sequencing and analysis of …

“Be Of Knightly Countenance”: Masculine Violence And Managing Affect In Late Medieval Alliterative Poetry And Batman: Under The Red Hood, Lisa D. Camp

Theses and Dissertations

This thesis is concerned with the legacy of cultural representations of masculine violence as it manifests in late medieval alliterative poetry and contemporary superhero comics, and the ways in which those manifestations are inflected by a particular set of images, motifs, and cultural underpinnings which transcend sociohistorical boundaries and that illuminate the ways culture sanctions certain forms of masculine violence. To understand how, as Patricia Ingham suggests in Sovereign Fantasies: Arthurian Romance and the Making of Britain, imagination infuses history towards particular “regime[s] of truth,” I argue that late fourteenth century Arthurian alliterative poetry and contemporary superhero comics instruct a …

Experimental Music In Higher Education: Toward A Pedagogy Of Creativity, Philip Melancthon Snyder V

Theses and Dissertations

Experimental music is rarely taught in higher education music programs but it could nevertheless be useful for providing students a methodology through which to develop creativity. This document seeks to find common ground between the seemingly disparate worlds of classical music and experimental music in pursuit of revealing the usefulness of experimental music practice for musicians trained in the classical tradition. In seeming contrast to classical music, experimental music values include process, indeterminacy, and non-subjectivity. This document shows that these aspects, despite seeming exclusive to experimental music, are in fact integral to all music. This document will also discuss writings …

The Leap In Place: Rethinking Key Concepts In The History Of Composition And The Return Of Lore., David Stubblefield

Theses and Dissertations

This dissertation attempts to affirm a key set of practical terms in order to guide Composition Pedagogy. These terms include error, language, voice, teacher neutrality, and rationality. In recent years, many of these terms have been discredited theoretically; however, they remain dominant in textbooks and in our actual teaching practice. The result has been a significant divide between theory and practice, resulting in a cognitive dissonance between our classroom activities and our scholarly activity. However, by presenting each of these terms as dynamic and performative, this dissertation invites the field to find productive practical possibilities inside of them. Moreover, the …

An Investigation Of Early Childhood Outdoor Play Areas And Social And Emotional Play, Brandy A. Smith

Dissertations and Theses @ UNI

The earliest early childhood programs were thought of as a garden for children or kindergarten (Snider, 1900). The father of kindergarten, Frederick Froebel (1885), considered the garden space critical in early childhood programs. While there is an understanding of the importance of outdoor play for young children, many current issues and challenges have drastically reduced the amount of time children spend in the outdoor environment (Kuh, Ponte, & Chau, 2013). Much of the time children do spend outside is devoted to physical movement, often in environments with traditional manufactured playground equipment (Czalczynska-Podolska, 2014). Outdoor play holds potential for multi-dimensional (Nedovic …

Resilience In Undergraduate Students: The Relation Between Personality, Social Support, And Cortisol Levels, Elisheva Joy Havlik

Dissertations and Theses @ UNI

The purpose of the current study was to investigate resilience in relation to personality, social support, and cortisol levels in response to a stress induction in a sample of 174 undergraduate students. It was hypothesized that resilience would be positively related to personality traits and perceived social support, and also would predict cortisol levels at baseline, reactivity to stress induction, and recovery after stress induction. Additionally, exploratory analyses investigated the moderating effects between variables to explain the process of resilience further. Participants completed self-report questionnaires (i.e. the CD-RISC, BFI, and the MPSS), provided saliva samples via a passive drool collection …

Reconstructing The Phylogeny And Characterizing The Patterns Of Molecular Evolution Of The Tetraploid Freshwater Suckers (Cypriniformes: Catostomidae), Zachary Evan Sperstad

Dissertations and Theses @ UNI

The Catostomidae, colloquially known as the suckers, is a family of freshwater fish endemic to North America and Asia. This family is hypothesized to have evolved sometime before or during the Paleocene (56-66 Mya) from a single tetraploid ancestor, which is thought to be the product of a hybridization event between two closely related, diploid cypriniforms. Currently, there are 79 recognized, extant species, some of which are difficult to discriminate between in the field. Despite the numerous studies that have aimed to reconstruct the evolutionary history of this family, little consensus exists for the relationships of the subfamilies within the …

Researchers, Not Dogs, Lack Control In An Experiment On Jealousy, Jennifer Vonk

Animal Sentience

Cook and colleagues (2018) have developed a clever method to measure fMRI in awake dogs in response to a number of interesting stimuli. As a result, they are able to determine neural correlates of observable behavior. They report that dogs may experience something akin to jealousy because they show greater amygdala activation in response to food being given to a fake dog versus food being placed in a bucket. However, several critical controls are missing which prevent the authors from being able to speak of jealousy.

Dogs Aren’T Jealous – They Are Just Asking For Accurate Information, Karen L. Overall

Animal Sentience

Awake fMRI offers us a unique opportunity to view and understand how dogs see the world and use the information in it. Given the limitations of behavioral assays and the small sample sizes inherent in these studies, labeling of patterns of canine behaviors using pop psychology terms may actually interfere with our understanding of canine brains and obscure for us a more parsimonious but exciting interpretation of canine behavior. We should use this window into how dogs think wisely.

Situating The Study Of Jealousy In The Context Of Social Relationships, Christine E. Webb, Frans B. M. De Waal

Animal Sentience

Whereas the feelings of other beings are private and may always remain so, emotions are simultaneously manifested in behavior, physiology, and other observables. Nonetheless, uncertainty about whether emotions can be studied adequately across species has promoted skepticism about their very presence in other parts of the animal kingdom. Studying social emotions like jealousy in the context of the social relationships in which they arise, as has been done in the case of animal empathy, may help dispel this skepticism. Empathy in other species came to be accepted partly because of the behavioral similarities between its expression in nonhuman animals and …

The Degeneracy Of Behavior And The Rise Of Neuroimaging To Measure Affective States In Dogs, Peter F. Cook, Gregory S. Berns

Animal Sentience

It is gratifying and significant that so many scientists from diverse fields are arguing in-depth regarding a particularly complex set of social emotions in a non-human animal. Emotions play a fundamental role in decision making and information processing. Neuroimaging is important in understanding the cognitive and emotional worlds of non-human animals and can help measure covert emotions lacking clear behavioral correlates. Various experimental approaches could clarify the relative importance of attachment and aggression in jealousy and whether the phenomenon we measured is more akin to human envy or jealousy. Reverse inference from amygdala activation is probably justified because behavior is …

Role Of Mammary Microenvironment In Promoting Left-Right Differences In Tumor Progression, Metastasis, And Therapeutic Response, Huda Issa Atiya

Theses and Dissertations

Metastasis is the main cause of death in breast cancer patients; however, there are currently no treatments available to treat or prevent metastasis. This is in part because regulators of metastasis are not yet fully understood. Over the past century researchers began to study metastasis regulators by different hypotheses, such as the seed and soil hypothesis which focuses on studying the role of cancer cells, the seeds, and the tissue microenvironment, the soil, in regulating metastasis. Although lots of studies have focused on the microenvironment of metastatic sites and their roles in regulating metastasis, limited studies have focused on the …

Effect Modification By Stroke To The Relationship Between Tooth Loss And Cognitive Decline, Amanda Collins

Theses and Dissertations

Background: A decline in cognitive functioning is one of the greatest burdens that older adults face. Studies indicate that periodontal disease is positively associated with cognitive decline. The link between stroke and cognitive decline is well-established, and literature supports that tooth loss and stroke are associated as well, but the role that stroke plays in the relationship between tooth loss and decline in cognitive functioning is, as of yet, unclear. This study uses data from the REGARDS cohort to examine the effect of stroke on the relationship between periodontal disease and cognitive function.

Methods: The REGARDS cohort is comprised of …

Exercise As A Therapeutic For Hiv-1-Associated Neurocognitive Deficits, Michael N. Cranston

Theses and Dissertations

Human Immunodeficiency Virus (HIV-1) afflicts nearly 38 million individuals worldwide (Joseph et al., 2013; “WHO | HIV/AIDS,” 2016). Despite the reduction in disease mortality due to increased use of antiretroviral medication, HIV-1 associated neurocognitive disorder (HAND) affects approximately 50% of HIV infected individuals (Antinori et al., 2007; Castellon, Hinkin, Wood, & Yarema, 1998; Castelo, Sherman, Courtney, Melrose, & Stern, 2006; Cysique & Brew, 2009; Heaton et al., 2011, 2015). The brain itself is particularly sensitive to HIV-1 related viral proteins and viral infection (Masliah, DeTeresa, Mallory, & Hansen, 2000), thus, it is vital to empirically examine potentially effective therapeutics which …

Movement Break Effects On Second Graders: An Action Research Study, Windy K. Sizemore

Theses and Dissertations

This paper describes an action research study regarding the amount of time elementary school children have to engage in movement and play during the school day. The teacher-researcher focused on using transitional movement breaks before math whole group instruction in an effort to answer the question: How do various types of movement breaks during instructional transitions impact off-task behaviors among second grade students during classroom instruction? The data results showed that physical activity related to students’ abilities to stay on-task during instruction when regularly scheduled movement breaks have been implemented as transitions. Student off-task behaviors decreased after using a physical …

Comparison Of Sentinel-2 And Landsat 8 Oli In The Mapping Of Soil Salinity In Hyde County, North Carolina, Eleanor Davis

Theses and Dissertations

This study presents the first comparison of Landsat 8 OLI and Sentinel-2A MSI imagery in identifying soil salinity using soil physiochemical, spectral, statistical, and image analysis techniques. By the end of the century, intermediate sea level rise scenarios project approximately 1.3 meters (4.2 feet) of sea level rise along the coast of the southeastern United States. One of the most vulnerable areas is Hyde County, North Carolina, where 440 square miles of agricultural lands are being salinized, endangering 4,200 people and 40 million dollars of property. To determine the best multispectral sensor to map the extent of salinization, this study …

Instrumentation For, And Application Of, Novel Electrochemical Tools For In Vivo Analysis Of Neurotransmitters In The Context Of Psychiatric Disease, Rhiannon Robke

Theses and Dissertations

ABSTRACTSerotonin’s involvement in many physiological processes including anxiety, stress, compulsivity, and mood has been speculated for decades. Insufficient progress in our understanding of serotonin chemistry is due to the lack of effective tools to selectively measure this neurotransmitter on a neurotransmission-relevant time scale in vivo. An analytical technique for serotonin measurements, fast-scan cyclic voltammetry (FSCV), was pioneered in the last decade in anesthetized rodents and is beginning to shed light on the complexity of serotonergic activity on a sub-second timescale. Complementary, more recent technological innovations have enabled ambient neurotransmitter levels to be determined every few seconds using a method called …
