Effects Of Clarity And Group Membership, Fatima Akia Martin

Master's Theses

Reciprocal-trust relationships are at the very foundation of our social contracts with one another. Trust and the implied promise of reciprocity have real world effects on how we make decisions in our personal and professional lives. When we have received a benefit from another person, and later have an opportunity to give a benefit back to that same person, we often use the level of trust implied by the initial benefit received as a guide to the amount of benefit we should return. The current study investigated how the clarity of the trusting individual's intentions to trust and his/her group …

The Role Of Central Metabolism And Electron Transport In Biofilm Formation By Vibrio Fischeri, Jakob Michael Ondrey

Master's Theses

Biofilms protect bacteria from environmental threats, including antibiotics; thus, biofilms formed during infections pose an increasing threat to human health. A natural model used to study biofilm formation in the context of a host is the symbiosis between Vibrio fischeri and its host, the squid Euprymna scolopes. Successful colonization depends on the formation of a biofilm and genes involved in making the polysaccharide matrix component, syp. In culture, biofilm phenotypes, including the formation of wrinkled colonies, similarly depend on syp. However, little is known about other factors that contribute to this phenotype. To expand the utility of currently available genetic …

The Contribution Of The Female Urinary Microbiota To Lower Urinary Tract Symptoms, Travis Kyle Price

Master's Theses

The recent finding that urine is not sterile raises a lot of questions: first and foremost, what microorganisms are present, and are these microorganisms correlated with clinical urinary symptoms? Recent work on the female urinary microbiota (FUM) found that the communities of microorganisms differ between women with no lower urinary tract symptoms (LUTS) and those with Urgency Urinary Incontinence (UUI) a form of over-active bladder syndrome. Specifically, a diverse or dysbiotic urinary microbiota was found to be associated with symptomatic women. This suggests the possibility that the FUM can be contributing to urinary symptoms. Conversely, it could also suggest that …

Predictors Of Prison-Based Drug Treatment In Illinois, Erin Elizabeth Sneed

Master's Theses

This study identifies the inmate characteristics that are predictive of accessing prison-based substance abuse treatment services in Illinois. Substance abuse treatment has shown to effectively reduce recidivism; however, only a small proportion of those in need of treatment have access to it. This study found that of the roughly 50% of inmates who were recommended for treatment, only 16.6% received treatment in prison. Bivariate and multivariate analyses confirmed that being a female inmate who was more educated, not gang-affiliated, had fewer prior arrests, and who was serving between 6-30 months in custody were the most likely to receive treatment. The …

Malaria Transmission Blocking Vaccines, Lukasz Jacek Sewera

Master's Theses

Malaria affects 198 million people and kills 584,000 each year, predominantly in Sub-Saharan Africa (WHO). The most severe form of malaria is caused by the protozoan parasite Plasmodium falciparum. Development of a vaccine against P. falciparum has been hindered by its complex life cycle with multiple antigenically distinct human and mosquito stages. To effectively prevent disease and reduce the parasite burden in populations, a vaccine will need to target multiple stages, including blocking transmission at the mosquito stage.

Antibodies generated against P. falciparum mosquito stage antigen Pfs25 can prevent parasite transmission from humans to mosquitoes. However, Pfs25 is poorly immunogenic …

Conditionalities Of The Knowledge Banks And The Financing Of Higher Education In West Africa: A Focus On Ghana, Nigeria, And Sierra Leone, Innocent Chima Ugwoke

Master's Theses

The purpose of this thesis is to understand how the loan conditionalities of the knowledge banks—the World Bank and International Monetary Fund (IMF) are affecting the funding of higher education in West Africa generally by particularly comparing Ghana, Nigeria, and Sierra Leone. The role of higher education has been linked with development, and development has remained a concerned issue in Africa. The commitment of the states in funding higher education in order to achieve the desired goal of development is continuously met with difficulty. The reliance of these countries on the loans of the knowledge banks, which are associated with …

Dna Methylation Patterns Of Specific L1 Loci On The Short Arm Of Chromosome 21, Sarah Ann Tincher

Master's Theses

While 10-15% of the human genome is composed of heterochromatic DNA, these regions are not included in the completed genome sequence. The short arm of chromosome 21 (HC21p) serves as a model for understanding the structure and function of heterochromatin. LINE-1 (L1) retrotransposons are underrepresented in heterochromatin, including HC21p, and have not been extensively studied in these regions. However, there are disproportionately more full length L1s on HC21p than in euchromatic genomic regions. Decreased DNA methylation in the promoters of these L1s on HC21p may allow them to facilitate heterochromatin formation, which would be analogous to their proposed role in …

Returning Citizens? The Path From Prison To Politics Among The Formerly Incarcerated, Quintin A. Williams

Master's Theses

This project examines the experiences of a group of formerly incarcerated persons involved in community organizing efforts for felon empowerment. Scholarly works often focus on what is being done on behalf of the formerly incarcerated, this work highlights how men and women with records advocate for themselves. Drawing on 18 months of participant observation and 18 in-depth interviews with a Chicago based group called FORCE (Fighting to Overcome Records and Create Equality) I found that meanings of redemption were essential to advocacy and operated as an imperative. The redemption imperative both constrained and enabled advocacy. It constrained advocacy in its …

The Impacts Of Family Environment And Stress Reactivity On Daily Mood For Low-Income Latino Adolescents, Stephanie K. Brewer

Master's Theses

Low-income Latino adolescents are at an increased risk for developing psychopathology, as the chronic stressors faced by those who grow up in poverty have an adverse cumulative effect, and the relationship between exposure to poverty and negative mental health outcomes is intensified for ethnic minority youth. One of the most impactful ways in which poverty causes deteriorations in adolescent mental health is through heightened levels of parent-child conflict. Another harmful result of the multiple stressors faced by poor youth is the dysregulation of the stress reactivity system. For Latino adolescents, problems with mood are a particular concern, as Latino adolescents …

The Protective Effect Of Kinship Support On The Adjustment Of Youth In Foster Care, Grace Jhe Bai

Master's Theses

The present study examined the contribution of characteristics of the family-of-origin, such as family functioning, to foster youth's psychological adjustment. With particular attention paid to foster youth's broader social contexts after separation from biological parents, this study also examined how kinship support influences the impact of child maltreatment and dysfunction of family-of-origin on foster youth's subsequent adjustment. Unlike previous studies, specific types of relatives (e.g., maternal aunt, paternal uncle, maternal great aunt, paternal grandmother) and their varying involvements were identified. Participants included 171 children and adolescents (mean age = 10.15; 50.3% male). Hierarchical ordinary least squares regressions were conducted to …

The Influence Of Eastern Oyster (Crassostrea Virginica) Reef Restoration On Nitrogen Cycling In A Eutrophic Estuary., Michael Hassett

Master's Theses

Oysters (Crassostrea virginica) are functionally extinct in the urbanized Hudson-Raritan estuary (HRE) in New York City, however, oyster restoration is promoted to mitigate nitrogen (N) pollution via oysters' filtration and excretion. Seasonally, I took 12 sediment cores (45 cm2) adjacent to and 10 m away from a recently constructed reef in the HRE. Cores were incubated in flow-through chambers with site water containing (1) no amendments, (2) 15N-ammonium, or (3) 15N-nitrate, from which I calculated coupled nitrification-denitrification and direct denitrification as isotope-enriched N2. Coupled denitrification was minimal at all sites while direct denitrification was elevated near the reef, suggesting organic …

Latino Youth With Spina Bifida: Psychosocial Functioning, Family Functioning, And Acculturation, Jaclyn M. Lennon

Master's Theses

Objective: Research on Latino youth with spina bifida (SB) is sparse. However, SB rates are highest in this ethnic group, and typically-developing (TD) Latino youth are at risk for poor psychosocial functioning. The aims of this study were to examine: (1) differences in psychosocial and family functioning between Latino and non-Latino Caucasian youth with SB; (2) family functioning as a predictor of youth psychosocial functioning as moderated by ethnicity; (3) the impact of acculturation on youth psychosocial and family functioning in Latino youth with SB. Methods: Participants were recruited as part of a larger, longitudinal study (Devine et al., 2012). …

Positive Peer Pressure Among Black American Youth And The Roles Of Ethnic Identity And Gender, Dakari Quimby

Master's Theses

Peer pressure is a phenomenon that affects many youth due to the importance of peer relations during adolescence (Brinthaupt, 2002). Consequences associated with negative peer pressure have been well documented, but the extant literature on positive peer pressure is sparse though it may be an untapped source of positive development (Padilla-Walker & Bean, 2009). The current study examined whether positive peer association, a form of peer pressure involving the indirect modeling of behaviors, can have a role in promoting healthy youth development longitudinally among African American adolescents living in low-income, urban, high violence neighborhoods. A sample of 316 African American …

Tcr Modifications To Enhance Expression, Chain Pairing, And Antigen Recognition For Adoptive T Cell Transfer, Kendra Foley

Master's Theses

T cell receptor (TCR) gene modified T cells for adoptive T cell transfer therapy have been shown to have clinical success in treating melanoma and other malignancies by redirecting the specificity of peripheral blood lymphocytes (PBL) to recognize tumor and/or viral associated antigens of choice. One of the challenges in using TCR gene modified T cells is the potential mispairing between endogenous and introduced alpha and beta TCR chains, allowing for unwanted off-target reactivity, autoimmunity, or impaired therapeutic efficacy. One approach to augment proper TCR chain pairing and to enhance T cell function involves the modification of the introduced TCR …

Social Policy Shifts And The Relationship Between Snap Workers And Their Clients, Latrese Annette Monden

Master's Theses

In an effort to better understand how federal social policy changes shape the ways in which public service workers assist their clients in obtaining food benefits through Supplemental Nutrition Assistance Programs (SNAP), previously known as food stamps, this study uses ethnography and interviews to capture the experiences of workers and their clients. Specifically, it examines how public service workers implement new policies while maintaining their professional identities and responding to the mission of their organization. These goals may be in tension. The key findings are that workers do not resist changes in policy because of the limitations of their job …

The most significant deduction …

The Relation Between Implicit And Explicit Self-Esteem Predicting Inconsistent Parenting, Bethany Otto

Master's Theses

Recent research has begun to examine insecure high self-esteem, which is characterized by low implicit (unconscious) and high explicit (conscious) self-esteem. However, little work has investigated its possible origins. Examining its origins is important because empirical findings have linked insecure high self-esteem to defensiveness, narcissism, in-group bias (Bosson et al., 2003; Jordan et al., 2003; Trumpeter et al., 2008), and anxiety (Bos, Huijding, Muris, Vogel, and Biesheuvel 2010). The current research investigated the possible origin of insecure high self-esteem in inconsistent parenting based on relevant research and theories that link parenting to the development of implicit and explicit self-esteem. Contrary …

Investigating The Role Of Cysteine In Biofilm Formation By Vibrio Fischeri, Priyanka Abhishek Singh

Master's Theses

Biofilms are an important area of medical research because bacterial biofilms can form on implants such as catheters and are highly resistant to antibiotics and other antimicrobials. The symbiosis between Vibrio fischeri-Euprymna scolopes, is good model to study biofilm. V. fischeri has 18 gene polysaccharide locus, syp, that is required for biofilm formation and colonization. A recent mutant study suggested the possibility that cysteine biosynthetic genes were involved in biofilm formation by V. fischeri, including cysH, cysJ, cysK, and cysN. My results supported a role for cysK and, to a lesser extent, cysH in biofilm formation. Finally, I have data …

The Bronze Artifacts Of Tall Jalul, Jordan, Christine T. Chitwood

Master's Theses

Background

It is quite common at excavation sites throughout the Near East to uncover the remains of metallic artifacts, though the practice of investigating these objects has fluctuated over the past 50 years of archaeometallurgical studies. Early scholars of archaeometallurgy, such as R.F. Tylecote, employed the use of elemental analysis, studying early metallurgical technologies necessary to create metallic implements around Europe and the Near East and paying close attention to the resources and energy exerted to manufacture each instrument. Other researchers compiled typological comparisons, building cultural identities off of stylistic features from the material culture. Since then, technological and elemental …

Selective Processing By The L3 Auditory Interneuron In Acheta Domesticus : Juvenile Hormone Iii And Protein Kinase C, Ashley Ranae Lynch

Master's Theses

Juvenile Hormone III (JHIII) is a prolific and essential hormone in insects, controlling many aspects of insect physiology such as egg development, nymphal and larval maturation, diapause and metamorphosis. In female crickets, Acheta domesticus, JHIII increases selectivity in phonotactic behavior, narrowing phonotactic choices for Syllable Periods (SPs) of the Calling Songs (CSs) that most closely resemble the natural call of the male. JHIII has been suggested to work through a pathway that activates the protein kinase C (PKC) molecule. Chelerythrine Chloride (CC) is a potent inhibitor of PKC action. This study analyzes the responses of the L3 auditory interneuron, which …

Expression And Characterization Of Ecm14, A Metallocarboxypeptidase From Saccharomyces Cerevisiae, Matthew James Schott

Master's Theses

Metallocarboxypeptidases are found in most organisms and function in the digestion and maturation of proteins. Ecm14 is a putative metallocarboxypeptidase found in the yeast Saccharomyces cerevisiae vacuole. The function of Ecm14 as an enzyme has been unclear due to the presence of active site amino acids not typically found in metallocarboxypeptidases, suggesting either no enzymatic activity or a unique mechanism. In order to investigate the enzymatic mechanism of Ecm14, expression of histidine-tagged Ecm14 protein was attempted in human HEK293T cell culture, S. cerevisiae, and baculovirus expression systems. No expression was detected in HEK293T cells in preliminary experiments. Expression in the …

Impacts Of Scholarship And Publication On Entry-Level Hiring: Public Services Applicants In Academic Libraries In The United States, James E. Hicks

Master's Theses

This study examines the impact of a single knowledge, skill, and ability (KSA), specifically research and publication experience, on the hiring decisions of selection committees for entry-level public services academic librarian positions in the United States. Current library and information science literature contains few studies focusing on a single KSA factor. For this study, respondents (n=141) from a selective sample of 382 institutions of higher education completed an online survey in January and February 2015. The results show that research and publication experience had a greater impact on hiring decisions at urban research universities with large full-time equivalent (FTE) student …

An Examination Of The Mass Limit For Stability At The Triangular Lagrange Points For A Three-Body System And A Special Case Of The Four-Body Problem, Sean Kemp

Master's Theses

While the three-body problem has been without an exact analytical solution for some 400 odd years, we have learned a great deal about the dynamics of three-body systems in that time. There are five points relative to two massive bodies where a third body will remain in a stable orbit. These are called the Lagrange points. Two of these points, located at the vertices of equilateral triangles, are stable equilibria. We find clear evidence for these stable points within our own solar system, most notably Jupiter's Trojan satellites.

It may be possible to place a massive body at one of …

Initial Consonant Mutation In Modern Irish: A Synchronic And Diachronic Analysis, Janine Fay Robinson

Master's Theses

This thesis presents an overview of the process of initial consonant mutation in Modern Irish. Initial consonant mutation is most simply described as a phonetic change in the initial consonant of a word triggered by a closed set of morphosyntactic environments. These triggers and environments are varied and difficult to generalize. Many attempts at classification have utilized current theories of phonology, morphology, and syntax to describe and explain the synchronic process, with the original motivation being a purely phonological environment that existed in earlier stages of the language. By examining the original mutation environments in comparison to the corresponding forms …

Using Satellite Remote Sensing, Field Observations And Wrf/Single-Layer Urban Canopy Model Simulation To Analyze The Oklahoma City Uhi Effect, Hengyue Zhang

Master's Theses

The Urban Heat Island (UHI) was investigated using satellite data, ground observations, and simulations with an Urban Canopy Parameterization in a numerical weather prediction model. Satellite-observed surface skin temperatures at Xi’an City and Oklahoma City (OKC) were analyzed to compare the UHI intensity for the two inland cities. A larger population density and larger building density in Xi’an City creates a stronger skin-level UHI effect. However, ground observed 2-m surface air temperature (Tair) data showed an urban cooling island (UCI) effect that occurred over an urban region in OKC during the daytime of July 19, 2003.

The sensitivity and accuracy …

The features of the smartphone make it an indispensible commodity of Western urban lifestyles. However, the most common problems of using a mobile device for work-related activities are limited screen space and poor input techniques. People in the workforce whose daily job entails being in a mobile environment generally prefer to carry light, mobile devices along with a pen and a notepad. The purpose of this study was to investigate optimal input modality for taking notes. The three modes of input evaluated were spoken notes, typing on the phone, and writing by hand using a pen and paper. The variables …

Influence Of Macromolecular Crowding On Water And Model Reaction Equilibria, Sai Sathyasree Dharmaraj

Master's Theses

Macromolecular crowding refers to the excluded volume in the cell by macromolecules (proteins, DNA, etc.). Crowding in the cell is relevant to the free motion of each macromolecule and may influence biological equilibria in general. The surface hydration of the crowding agents is expected to alter the average properties of water in the solution, which in turn may also affect molecular interactions. Because the living cell contains a concentration of 300-400 g/L of macromolecules, it is crucial to study the properties of crowded solutions to understand the environment of a cell. The focus was to study the thermodynamic properties of …

Effects Of Stress On 9-1-1 Call-Takers And Police Dispatchers: A Study At The San Jose Police Department, Kimberly D. Turner

Master's Theses

This research addresses the significant gap in literature related to stress among 9-1-1 call-takers and dispatchers. The relationship between perceived stress and work-life balance, fairness at work, support at home, and work control as well as physiological and psychological outcomes is examined. Survey responses were collected during the summer of 2012 from 89 police 9-1-1 call-takers and radio dispatchers of the San José Police Department Communications Division in San José, California. Using hierarchical multiple regression analysis, I found those who enjoy a balance between work and personal life experience less stress. Also, greater stress is associated with more psychological and …
