Beware Of Ips In Sheep's Clothing: Measurement And Disclosure Of Ip Spoofing Vulnerabilities, Alden Douglas Hilton

Theses and Dissertations

Networks not employing destination-side source address validation (DSAV) expose themselves to a class of pernicious attacks which could be prevented by filtering inbound traffic purporting to originate from within the network. In this work, we survey the pervasiveness of networks vulnerable to infiltration using spoofed addresses internal to the network. We issue recursive Domain Name System (DNS) queries to a large set of known DNS servers world-wide using various spoofed-source addresses. In late 2019, we found that 49% of the autonomous systems we tested lacked DSAV. After a large-scale notification campaign run in late 2020, we repeated our measurements in …

Algal Biodiversity Survey Of The Middle Chattahoochee River Using Dna Metabarcoding, Amanda Howell

Theses and Dissertations

Aquatic plants play vital roles in water systems by providing ecological services, and one group that is understudied is algae. Algae play a crucial role in water systems as bioindicators and primary producers. They can be challenging to identify with the naked eye, so researchers have been using DNA metabarcoding, where DNA belonging to specific taxa can be isolated and identified from water samples. The objective of this study was to conduct an algal biodiversity survey on the middle Chattahoochee River system in Georgia. Water samples (1L) were filtered and sent to RTL Genomics for sequencing and processing; the data …

Millais’ Modern Christ: Religion And Critical Responses To The Pre-Raphaelite Brotherhood In Nineteenth Century England, Ashley Morse

Theses and Dissertations

This thesis explores how the press reviewed Pre-Raphaelite paintings in the years 1849 and 1850 with a partial review of 1851. In particular, the focus is on the controversial painting Christ in the House of his Parents by John Everett Millais. This painting became a physical symbol of the many fears that the new modern age brought to Victorian England. Catholic, Irish, and Protestant tensions had been mounting throughout the nineteenth century in England prior to the debut of the painting. Politics and law were beginning to relax restraints on Catholicism in addition to the increased immigration of Irish Catholics. …

Making Yourself At Al-Dar: On Islamic Education, Social Imaginations, And Affective Possibilities, Alia Amr Amin Shaddad

Theses and Dissertations

This thesis explores the Dar as an alternative space of knowledge, and unravels how its different contexts and rhythms allow us to imagine what that alternative means in the everyday. In order to do so, this thesis unpacks questions of space, time, subjectivity, and potential. I look at the ways in which this Dar is constituted as a space through its relations with other spaces and by engaging questions of temporality. By doing so, this thesis maps this space to make clear what and how it is, and highlights the historical and geographical context it exists in. This also includes …

The Spatial Variability Of Crime: A Review Of Methodological Choice, Proposed Models, And Methods For Illustrating The Phenomenon, Matthew D. Spencer

Theses and Dissertations

The spatial analysis of crime has occurred for nearly two centuries. Within criminology, research interests that have developed from the use of spatial methodologies seek to identify the spatial variability and concentration of crime. The first focus utilizes spatial statistics and mapping to describe and illustrate spatial variability. The second focus uses statistical techniques to describe levels of concentration such as the percentage of crime attributed to a unit. Due to the larger breadth of work and multiple analytical components the former will be the focus of this research.

This multi-study dissertation explores the methods currently used to study the …

“Hungering And Thirsting” For Education: Education, Presbyterians, And African Americans In The South, 1880-1920, Rachel Marie Young

Theses and Dissertations

This thesis investigates the relationship between the white-dominated Presbyterian Church in the United States of America (PCUSA) and African Americans from 1880-1920, exploring the motivations, philosophies, and strategies of the PCUSA and the ways that they used education to achieve their goals of helping forge educated and devoutly Christian African Americans. The church’s history highlights the ways in which Presbyterian paternalism developed in the years leading up to 1880, as well as contradictions in white church members’ understandings of race relations and their conflation of civic duty with religious responsibility. The church’s efforts in primary education provide a window into …

Composition, Context, And Community Integration: Evaluating The Relative Strength Of Environmental Factors On Mental Health Outcomes Using A Social Ecology Model, Douglas John Archie Iii

Theses and Dissertations

The relationship between environmental factors and individual health outcomes has historically been a major area of interest for multiple scientific disciplines. However, the specific environmental factors relevant for describing this relationship and effective measuring methods are unclear. One approach that may assist in addressing these issues is by analyzing this relationship using a comprehensive theoretical framework. This study used a social-ecological model first proposed by Moos and colleagues (Insel & Moos, 1974: Moos & Moos, 1976) to investigate connections between environmental factors and mental health recovery outcomes of psychiatric distress, management of mental health symptoms, and recovery-oriented behavior. A series …

Disparities In Programming African American Solo Vocal Music On College Campuses Across The United States, Ramelle Brooks

Theses and Dissertations

This study investigates the representation of African American composers within the solo vocal literature genre of classical music. Literature suggests the music of African American composers is seldom taught in classical musical studies. The study explored one publicly available college recital database from each U.S. geographical region (Northeast, Midwest, South, West), which included listings of songs performed at each recital. The researcher recorded the number of recitals including African American composers and provided a numerical breakdown of song genres associated with African American Americans that included African American arts songs, Spirituals, Blues, Gospel, Jazz, and operatic arias.

Land, Racial Formations, And Power: Exploring The Network Of Power Relationships During Climate Change Planning In Coastal South Carolina, Teresa Norman

Theses and Dissertations

Climate change projections for the coastline of South Carolina predict that by mid-century there will be around 1.2 feet of sea level rise, and potentially up to 4 feet of rise by 2100. Additionally, climate change is linked to intensified hurricanes, a hazard for the South Carolina coastline every year. Both of these scenarios result in increases in the regularity and severity of coastal flooding, making the threat of permanent or temporary displacement (relocation) from coastal lands a reality. This is a particularly pressing matter for African American communities already made vulnerable by the long history of racial discrimination in …

How Do Adults Who Are Blind Desribe Their Quality Of Life?, Loreta Dylgjeri

Theses and Dissertations

This phenomenological study aimed to understand the Quality of Life (QOL) of six adults who are blind in the communities where they live or work. QOL is a construct that attempts to define what it means to “live the good life” (Schalock & Verdugo, 2002). To understand how individuals who are blind describe their QOL, we need a thorough understanding of how they describe their QOL based on their own lived experiences, beliefs, understandings, and attitudes towards the QOL. This study used a phenomenology method and was theoretically based on the QOL theory and its core domains and indicators, as …

Satellite Observations And Spatiotemporal Assessment Of Salt Marsh /Dieback Along Coastal South Carolina (1990-2019), Huixuan Li

Theses and Dissertations

Coastal wetland mapping is often difficult because of the heterogeneous vegetation compositions and associated tidal effects. Past studies in the Gulf/Atlantic coast states have reported acute marsh dieback events in which marsh rapidly browned and thinned, leaving stubble of dead stems or mudflad with damaged ecosystem services. Reported marsh dieback in South Carolina (SC), USA, however, have been limited. Previous studies have suggested a suite of possibly abiotic and biotic attributes responsible for salt marsh dieback. However, there are no consensus answers in current literature explaining what led to marsh dieback in past decades, especially from the spatiotemporal perspective. In …

Utilization Of Bioinformatic And Next Generation Sequencing Approaches For The Discovery Of Predictive Biomarkers And Molecular Pathways Involved In Bovine Respiratory Disease, Matthew Adam Scott

Theses and Dissertations

Bovine respiratory disease (BRD) is a highly dynamic disease complex that results from host, microbial agent, and environmental interactions. Despite nearly a century of targeted research, BRD remains the most economically damaging disease in beef cattle production and appears to be increasing in global incidence. While modern modalities for BRD detection exist, clinical diagnosis and management decisions largely depend upon clinical observations and their associated risk of disease. Though these approaches lack precision, they remain in use for many reasons, including fiscal and time constraints within beef production systems. Advancements in high-throughput sequencing have demonstrated the ability to provide insight …

Assessment Of Great Basin Bristlecone Pine (Pinus Longaevaâ D.K. Bailey) Forest Communities Using Geospatial Technologies, David Richard Burchfield

Theses and Dissertations

Great Basin bristlecone pine (Pinus longaeva D.K. Bailey) is a keystone species of the subalpine forest in the Great Basin and western Colorado Plateau ecoregions in Utah, Nevada, and California. Bristlecone pine is also the world's longest-lived non-clonal organism, with individuals occasionally reaching ages up to 5,000 years old. Because of its longevity, bristlecone pine contains an important proxy record of climate data in its growth rings. Despite its ecological and scientific importance, bristlecone pine's distribution and associated environmental drivers are poorly understood. Geospatial technologies, including unmanned aircraft systems (UAS), remote sensing, geographic information systems (GIS), and spatial modeling techniques …

Influence Of Carbon Sources On The Pathogenicity Of Mycoplasma Pneumoniae, Travis Anthony Salinas

Theses and Dissertations

Mycoplasma pneumoniae is a human respiratory tract pathogen and one of the best-characterized minimal bacteria. It is a serious problem because of health problems it can cause as it can be detrimental to humans and the occurrence and aggravation of systemic involvement in M. pneumoniae infection occur via multiple immunological pathways. With its major source of carbon and energy coming from phospholipids, Mycoplasma pneumoniae thrives on lung epithelia. In Mycoplasma pneumoniae, pathogenicity is closely related to carbon metabolism. By testing carbon sources in well plates and growth curves to analyze how growth is affected in Mycoplasma pneumoniae and measure optical …

This is done through an examination of Irish and Tejano Tory motivation in supporting Mexico and military participation in the Texas Revolution. This work also examines ideas of economic opportunity, social acceptance, personal conservatism, distrust of foreign settlement, and fear of invasion or reprisal as factors in Toryism or loyalism. Militarily, this thesis examines Tory military roles alongside Mexican forces …

Identifying Unknown Sources Of Nitrate In Two Central Illinois Watersheds, William Andrews

Theses and Dissertations

Nitrate pollution is a major environment problem facing many agriculturally intensive areas around the world. In the midwestern USA, upstream tributaries to the Mississippi River via the Mackinaw and Illinois rivers, local excess nitrate can create problems with the safety of drinking water. In central Illinois, lakes, which are regulated and designated for use as municipal water supply, can periodically exceed EPA drinking water criteria for nitrogen. Lake Bloomington of the Money Creek watershed is the primary source of water for the City of Bloomington, whereas Evergreen Lake of the Six Mile Creek watershed serves as auxiliary supply. Both watersheds …

Emotional Geographies Of Beginning And Veteran Reformed Teachers In Mentor/Mentee Relationships, Emily Joan Adams

Theses and Dissertations

Reformed teaching is better for students' conceptual understanding compared to the more popular traditional style of teaching. Many beginning teachers wanting to teach reformed conform to traditional teaching within their first couple years of teaching. I argue that this can happen because the emotional labor to continue teaching reformed without support is too high. Having a reformed math mentor can decrease this emotional labor and provide more support to beginning reformed teachers. This study builds on and adds to Hargreaves (2001) emotional geography framework to better understand the emotional closeness/distance beginning and veteran reformed teachers have talking about their practice. …

Detecting Remnants Of The Past: Archaeo-Geophysical Prospection Of Fremont Sites In Southern Utah Valley, Jacob P. Jepsen

Theses and Dissertations

The variable contexts of Fremont habitation sites in Utah Valley often make identification of those sites very challenging for archaeologists. Pit houses and other structures throughout the valley are frequently in plowed fields or other disturbed contexts that obscure their more exact location and nature. The application of geophysical technologies at archaeological sites throughout the world, including in North America, has proven to be an effective means of subsurface archaeological survey. However, geophysical techniques have been underutilized in Fremont archaeology. This paper reports on the employment of two geophysical methods, ground-penetrating radar (GPR) and fluxgate gradiometer surveys, at three known …

On Displacement And Music: Embodiments Of Contemporary Nubian Music In The Nubian Resettlements, Fayrouz Kaddal

Theses and Dissertations

Between 1961-1964, an estimated number of 113’000 Nubians, who were living south of the site of the Aswan High Dam, the area now beneath Lake Nasser, and Wadi Halfa, north of Sudan, were displaced to an area near Kom Ombo, 20 kilometres away from the Nile and 50 kilometres north of Aswan. This major project of resettlement occurred for the construction of the Aswan High Dam, Nasser’s signature mega-project. The 1961-1964 displacement was the culmination of earlier waves of relocation that Nubians witnessed during their recent history. In 1902 the British constructed the Aswan (lower) Dam by the first cataract …

Taking The Pulse Of Undergraduate Introductory Geographic Information Systems Courses, Christopher Krause

Theses and Dissertations

As colleges and universities expand their geographic information systems (GIS) course offerings, the pedagogies involved in teaching such courses ought to be critically evaluated. Existing research concerning the teaching of geospatial technologies has been characterized as “sparse, inconsistent, and overly anecdotal” (Baker et al., 2015, p. 118). Answering the call for “more systematic and replicable” (p. 118) GIS education research, this study adopted a suite of mixed methods used within other discipline-based education research (DBER) and deployed them in introductory GIS courses. These methods included classroom observation protocols, interview protocols, focus group protocols, and student questionnaires.

This research had three …
