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 …

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 …

The Validity Of Height As A Determinant Of Takeoff Distance To Hurdle One In Ncaa Division Iii Hurdlers 2017, Phillip Wiltshire

Master's Theses

The purpose of this study was to determine if the relationships between the height of a hurdler and the takeoff distance to the first hurdle for men and women as reported by Frye (2008) were valid for NCAA Division III 100 m and 110 m hurdlers. With no specific research reported to validate Frye’s data, it is unclear how the suggested takeoff distances were developed. It is also unclear whether hurdler height or another factor is the main determinant of takeoff distance for the high hurdlers. Participants in this study were three female 100 m hurdlers and four male 110 …

Lip Detection And Adaptive Tracking, Benjamin Wang

Master's Theses

Performance of automatic speech recognition (ASR) systems utilizing only acoustic information degrades significantly in noisy environments such as a car cabins. Incorporating audio and visual information together can improve performance in these situations. This work proposes a lip detection and tracking algorithm to serve as a visual front end to an audio-visual automatic speech recognition (AVASR) system.

Several color spaces are examined that are effective for segmenting lips from skin pixels. These color components and several features are used to characterize lips and to train cascaded lip detectors. Pre- and post-processing techniques are employed to maximize detector accuracy. The trained …

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 …

“Creating A New Mythos”: Reassessing Race Standards And Latina/O Students, Margarita Vizcarra

Master's Theses

This research will focus on the race and ethnicity categories used to classify people in the United States in relation to school age students. The Office of Management and Budget (OMB) first standardized federal race and ethnicity categories in 1977 in order to enforce compliance with civil rights laws. In 1997 revisions were made to these standards due to increasing criticism by the public, advocacy groups, and government agencies (Williams, 2006). The 1977 decision by the OMB designated the category of Hispanic, or Latino, as an ethnicity rather than a race which was once again upheld in the 1997 update. …

Depressive Symptoms, Neuropsychological Functioning, And Self-Management In Youth With Spina Bifida: Direct, Mediating, And Reciprocal Pathways, Alexa Stern

Master's Theses

Although successful self-management of health care responsibilities is critical to meeting the developmental demands associated with the transition to adulthood in youth with spina bifida (SB), research on individual factors impacting self-management in this population is sparse. Given the increased risk for cognitive deficits and development of depressive symptoms in this population, this study utilized a longitudinal, multi-method, multi-informant design to examine two pathways through which depressive symptoms and neuropsychological dysfunction may be associated with medical autonomy and adherence in youth with SB.

Bootstrapped mediation analyses revealed that teacher-reported depressive symptoms significantly mediated the respective relationships between attention and working …

The Devil's In The Emails: A Sociological Examination Of Organizational Failure, William Howard Burr

Master's Theses

It is often argued that the market, with its "invisible hand," displays an inherent bent towards maximizing utility and delivering the "greatest good to the greatest number." Faith in the market to act as benevolent overlord is not only misguided but, as revealed during the Great Recession, a fantasy. Analyzing emails made public following the Lehman Brothers bankruptcy, this paper considers the organizational culture within Lehman Brothers leading up to history's largest bankruptcy in order to emphasize the role of interaction within an outcome otherwise uncritically categorized as the unavoidable product of market fluctuations. Demonstrating how Lehman employees adopted the …

Utilizing Single-Molecule Fret Methods To Study Conformational Changes In Trim5Α, Margret Suzanne Bradley

Master's Theses

Single-molecule FRET (smFRET) is a method by which dynamic conformational changes can be monitored in a protein microscopically and in real time. smFRET relies on the creation of FRET (Förster Resonance Energy Transfer) between small molecule fluorophores conjugated to the biomolecules of interest. FRET efficiency allows calculation of interfluorophore distances. Changes in FRET efficiency represent changes in protein conformation which can inform further structural and molecular studies of the protein of interest. For example, in the Campbell Lab, we study the protein TRIM5α, an antiretroviral cellular protein which can cause premature dissociation of the HIV capsid core by an unknown …

Using Tcr Transgenic, Gp100 Reactive T Cells And Checkpoint Inhibition To Target Lymphangioleimyomatosis, Christian Ankney

Master's Theses

Lymphangioleiomyomatosis (LAM) is a low-grade neoplastic disease affecting primarily women. It is characterized by cystic lung disease as well as renal and retroperitoneal tumors called angiomyolipomas and lymphangiomas. Tumor cells have smooth muscle features as well as neuroendocrine cell surface markers, and the disease can be diagnosed by HMB45 staining of tumor cells. We questioned whether expression of melanocytic antigens, specifically gp100, creates an opportunity to treat LAM by adoptive T cell transfer. LAM lung lesions demonstrate poor immune surveillance, therefore adoptive T cell transfer could offer benefits in this disease.

A link was made between melanoma and depigmenting vitiligo …

Functional Studies Of Novel Mosquito Stage-Specific Genes In The Malaria Parasite, Plasmodium Berghei., Kaitlyn Kiernan

Master's Theses

The development and survival of the malaria parasite Plasmodium within its mosquito vector is not very well understood. When the parasite is taken up by an Anopheles mosquito, it is exposed to digestive enzymes, reactive oxygen species, increasing pH, decreasing temperature, and a diverse microbial flora. Our lab is studying the adaptive mechanisms underlying parasite survival in this hostile environment, one of which is movement out of the midgut. In order to escape the midgut, the parasite develops into an elongated, motile form called the ookinete. I am investigating two genes, thioredoxin-like protein 1 (trxl-1) and subpellicular microtubule protein 1 …

Filling Pews, Speaking Truth: Pro-Life Ministry In A Liberal Catholic Parish, Jonathan Neidorf

Master's Theses

Scholars of the pro-life movement in the United States have extensively documented how pro-lifers in this country feel that their cause is embattled by society (Williams and Blackburn 1996; Maxwell 2002; Munson 2008). Other research argues that conservative Catholics tend to feel that their Church is swept up in an increasing liberalization in greater society, which serves to compromise core moral tenets of the faith (Leege 1988; Weaver and Appleby 1995; Wedam 1993). No thorough research exists examining how pro-life Catholics see their Church's and their parish's liberalism as directly suppressing their pro-life work. In this ethnographic study of a …

Phenotyping Temperature-Sensitive Coronaviruses, Amani Eddins

Master's Theses

Coronaviruses (CoVs) can cause a range of symptoms; from a mild common cold to life threatening acute respiratory distress syndrome (ARDS) upon infection. These emerging viruses have the ability to be highly pathogenic and detrimental to the human population. Two prime examples of CoV emergence, SARS-CoV (Severe Acute Respiratory Syndrome) and MERS-CoV, (Middle Eastern Respiratory Syndrome), which exhibits the pandemic potential of emerging CoVs that gain human tropism. Given the increasing potential of an emerging CoV outbreak there is a state of urgency to develop vaccines that will help protect the human population against current and future circulating strains. The …

The Unconventional Secretion Of Alpha-Synuclein By Autophagic Mechanisms And The Novel Characterization Of Pathological Alpha-Synuclein Associated Extracellular Vesicles, Kevin Burbidge

Master's Theses

Synucleinopathies are a group of neurodegenerative diseases associated with the intracellular accumulation of aggregated α-synuclein, a neurotoxic process resulting in cell death. Research indicates that pathology results from α-synuclein misfolding and self-propagation, as well as, cell-to-cell transmission. Furthermore, pathological α-synuclein transmission may occur through unconventional secretion.

In this thesis, we investigated how autophagy influences unconventional secretion of our novel α-synuclein dual-split protein model that we first verified by reproducing documented results from treatment of known autophagic regulators. Afterwards, we investigated how knocking out autophagic proteins ATG7 and Beclin-1 influenced α-synuclein secretion.

Additionally, we developed a methodology for analyzing extracellular vesicles …

Perceived Partner Sexism And Stigma Consciousness: How 'Prince Charming' Undermines Relationship Satisfaction, Danielle Lauren Kellogg

Master's Theses

Perceived discrimination (outside of the relationship) relates to negative relationship outcomes, moderated by stigma consciousness (DeHart, 2017). Women who report higher (versus lower) levels of perceived partner benevolent sexism (i.e., perceptions of one's partner's endorsement of sexist attitudes) experience more negative relationship outcomes as well (Hammond & Overall, 2013; Hammond & Overall, 2014; Hammond & Overall, 2015). In addition, relationship partners adopt more traditional gender roles after becoming parents, which fosters benevolent sexism (Trillingsgaard, Baucom, & Heyman, 2014). In this study, married or cohabiting women with children were randomly assigned to either a sexism manipulation or control condition, prior to …

Understanding The Level Of Achievement Bilingual Education Fosters In Students, Erica Mallett

Master's Theses

Traditional approaches to examining the effectiveness of bilingual programs typically compare them to monolingual programs and rarely discuss the meaning and complexity of the notion of achievement therein. A vertical case study framework is used to examine this local phenomenon at a bilingual elementary school in Chicago, Illinois across local, national, and global contexts. This vertical case study aims to answer the question; how does a bilingual program define the notion of achievement and work to facilitate that achievement for students? To do this, I conducted interviews and analyzed policy documents to examine how achievement is defined in bilingual education …

Comparing The Risk Factors Of Recidivism For Offenders With And Without Mental Illness, Meghan J. Mahoney

Master's Theses

This study examined which risk factors were predictive of recidivism among inmates released from Illinois Department of Corrections (IDOC) who had no mental illness, a non-substance abusing mental illness (non-SUD MI), a substance use disorder (SUD), or a co-occurring mental illness and substance use disorder (COD). The predictors of being returned to prison or being rearrested for a violent, property, or drug crime were compared across these four groups. A secondary data analysis was conducted on data obtained by Olson, Stalans, and Escobar (2016) for a study examining the predictors of recidivism for inmates released from IDOC in 2007. Logistic …

Impact Of Visitation With Incarcerated Fathers On Behavioral Adjustment Among Children In The Foster Care System, Lauren Ashley Hindt

Master's Theses

This study sought to examine whether in-person visitation with incarcerated fathers related to less behavioral problems among children in foster care. The sample consisted of 282 youth (M = 10.18, SD = 2.36 years). Data were collected from the Illinois Department of Children and Family Services. Hierarchical Generalized Linear Modeling revealed paternal incarceration was associated with increased externalizing slope trajectories (ß1515 = .18, p = .025), but not internalizing. African American youth had lower externalizing slope trajectories compared to the remainder of the sample (ß20 = -.14, p = .032). The association between paternal incarceration and externalizing was attenuated …

Getting Students Employed: 21st Century Learning Competences And Career Competences, Kelly Cebold Sundberg

Master's Theses

This thesis explores the nexus between education and the economy in the 21st century knowledge-based economy to understand the relationship between the learning competences – as described in 21st century frameworks – and career competences – as recommended in the job descriptions of available employment opportunities. Theoretically, this study is grounded in human capital theory and it explores the indiscriminate nature of the data regarding a student’s required education level to achieve the prescribed learning competences. With the aid of a quantitative content analysis of selected employment opportunities, the research sought to explore: How are learning competences, as outlined by …

Comparative Study Of Broadband Photometry Relations For Ultra-Diffuse And Normal Galaxies In The Coma Cluster, Maria Babakhanyan Stone

Master's Theses

Ultra-diffuse galaxies are a novel type of galaxies discovered first in the Coma cluster. These objects are characterized simultaneously by large sizes and by very low counts of constituent stars. Conflicting theories have been proposed to explain how these large diffuse galaxies could have survived in the harsh environment of clusters. To date, thousands of these new galaxies have been identified in cluster environments. However, further studies are required to understand their relationship to the known giant and dwarf classes of galaxies. The purpose of this study is to compare the trends of inner and outer populations of normal members …

Mobile Doppler Lidar Observations Of The Convective Boundary Layer Over California, Christopher Paul Camacho

Master's Theses

A series of transects using a truck-mounted Doppler LiDAR were conducted to obtain mobile vertical profiles of the backscatter intensity and radial velocity across California. Using the backscatter and velocity profiles, several techniques were used to estimate the depth of the convective boundary layer (CBL). The CBL was estimated from the backscatter profiles using three analyses: (1) the Haar wavelet covariance, (2) the variance, (3) the gradient. These analyses were compared to vertical velocity variance, which uses a specified threshold (0.15 m2 s-2) to determine CBL height. The accuracy of the backscatter analyses was heavily dependent on strong aerosol loading …

Diet Induced Obesity Alters Muscle Spindle Afferent Function In Adult Mice, Lubayna Elahi

Master's Theses

Individuals with obesity are more likely to fall and exhibit balance instability. The reason for this is likely multifactorial, but there is some evidence that sensory function is impaired during obesity. We tested the hypothesis that muscle proprioceptor function is compromised in a mouse model of diet induced obesity. We used an in vitro muscle-nerve preparation to record muscle spindle afferent responses to physiological stretch and sinusoidal vibration. We compared the responses of mice on a control diet (10% kcal fat) with those eating a high fat diet (60% kcal fat) alone or in combination with either aspirin (120mg/kg/day in …

The Moderating Effect Of Leader-Member Exchange On The Relationship Between Job Characteristics And Organizational Commitment, Caitlin Sullivan

Master's Theses

There is a phrase “You don’t leave the company; you leave a manager.” But what if the job is perfectly designed to lead to organizational commitment: will the manager still have that much of an influence? This study examined the moderating effect of Leader-Member Exchange on the relationship between the Job Characteristics and Organizational Commitment. 220 employees from various countries and industries were surveyed regarding their current job, commitment to the organization and their relationship with their manager. Results showed that the core job dimensions based on the Job Characteristics Model were independently and uniquely related to affective and normative …

West Indian Manatee (Trichechus Manatus) Habitat Characterization Using Side-Scan Sonar, Mindy J. Mclarty

Master's Theses

In this study, the reliability of low cost side-scan sonar to accurately identify soft substrates such as grass and mud was tested. Benthic substrates can be hard to classify from the surface, necessitating an alternative survey approach. A total area of 11.5 km² was surveyed with the sonar in a large, brackish mangrove lagoon system. Individual points were ground-truthed for comparison with the sonar recordings to provide a measure of accuracy. Five substrate types were identified: Dense seagrass, sparse seagrass, mangrove soil, mangrove soil with rock, and silt. A zoned benthic substrate map was created from the sonar recordings. …

Glaucous-Winged Gull Predation On Chicken Eggs Treated With A Uv-Blocking Agent, Athena T. Smith

Master's Theses

Egg cannibalism plays a major role in the life histories of Glaucous-winged Gulls (Larus glaucescens) breeding at Protection Island, Washington. Gulls, along with other birds, visualize reflected ultraviolet (UV) light and I wondered if reflected UV light plays a role in determining which eggs are selected for cannibalization. Motivated by studies showing that tree-nesting bird eggs coated with a UV-blocking agent were less subject to predation than control eggs, I tested whether ground-nesting Glaucous-winged Gulls would preferentially predate control chicken eggs over those coated with a UV-blocking agent. Early during five mornings I formed artificial nests at randomly-determined …

Revisiting The Date Of Stratum V At 'Araq El-'Emir, Jordan, Daniel A. Ulvoczky

Master's Theses

Problem

Paul W. Lapp excavated at ‘Araq al-‘Emir and dated Stratum V to Iron Age I with an occupation gap before later periods. Later findings by scholars suggested a later date for this stratum, but no one has reviewed the original material in order to complete this. This study revisited the date of Stratum V using Lapp’s original sherds and field notes.

Method

The original sherds and field notes were borrowed from Nancy L. Lapp at Pittsburgh Theological Seminary. The data in the field notes was cross-examined with the sherds to identify the relevant sherds. A comparative analysis was conducted …

The Relationship Of Law And Grace In The Hermeneutics Of New Covenant Theology, Carlos J. Cruz Pacheco

Master's Theses

Problem

This thesis evaluates the offer by New Covenant Theology of an interpretation of salvation history that stands in criticism of interpretations offered by Covenant Theology and Dispensationalism. Does New Covenant Theology demonstrate a distinctive view of the law-grace relationship that brings new perspectives on important theological and hermeneutical issues such as the relationship between the Old and New Testaments, and the Sabbath. Are New Covenant theologians correct in their claim that their system presents the best interpretation of salvation history, and of the law-grace relationship?

Purpose

The purpose of this investigation is to evaluate New Covenant Theology’s hermeneutics by …

The Impact Of The Imminence Of The Parousia On The Mission Of The Seventh-Day Adventist Church, Bogdan Platon

Master's Theses

The imminence of the Parousia influenced the mission of Seventh-day Adventist church in all its history. The problem of this thesis is the extent to which the expectancy of the soon Parousia influences the concept about and the attitude towards mission in the Seventh-day Adventist church. Is Parousia the main motivation for the mission of the church or not? If Parousia determines the mission, what are the aspects associated with it that should drive the church mostly?

This thesis has a multidisciplinary approach: exegetical, historical and systematical. The study examines how the Bible history presents the impact of expectation upon …
