Stalking On The Screen: Examining Media Portrayals Of Relational Stalking Behavior, John Robert Macarthur

Theses and Dissertations

I coded a random sample of 266 movies to test whether previous researcher’s assertions that the media legitimizes unwanted courtship persistence (UCP) and minimizes stalking behavior is true. Consistent with their assertions, I found that the media does frequently depict stories of unwanted courtship persistence, and they were portrayed, on average, as acceptable. Although pursuers were generally portrayed positively, pursuers who engaged in UCP were more likely to be portrayed negatively than non-UCP pursuers. However, UCP pursuers were more successful than non-UCP pursuers in winning over their love interest. Using Cupach and Spitzberg’s (2004) Obsessional Relational Intrusion (ORI) scale, I …

Syngas Production From Biomass Pellets In A Downdraft Gasifier And The Removal Of Oxygen From Syngas, Rui Li

Theses and Dissertations

In pellet production, the parameters, such as densification pressure, temperature, feed moisture content, and coal and biomass concentration, that affected pelletizing and pellet quality were investigated. Gasification was carried out in a downdraft gasifier by using red oak hard wood as the feedstock. The raw syngas primarily contained carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and nitrogen (N2) as well as contaminants such as ash, water vapor, ammonia, and oxygen. Ash was removed with the filter bag. Water vapor was removed by desiccant absorption. Ammonia was removed by water scrubbing. Oxygen was removed by a CuO/CeO2-Al2O3 catalyst …

The Effect Of Variable Organic Matter On Site Productivity, Soil Nutrients, And Carbon On A Southern Loblolly Pine Plantation, Jason Craig Mack

Theses and Dissertations

This study examined the effect of manipulating forest floor and harvest residue inputs on nutrient availability and carbon content in the context of intensive forest management. Treatments were removal and addition of forest floor and slash, and a reference. Tree volume, litterfall, and root biomass were measured to assess aboveground productivity and soil moisture and temperature, available nitrogen and phosphorus, O-horizon, and mineral soil for below ground processes. Organic matter additions increased stand bole volume, carbon at 20-60cm, and total nitrogen in the mineral soil. Severely removing the floor and harvest residues did not result in any large differences in …

The Hinterland: Compilation Of Nearby Brown Dwarfs And Ultracool Stars, Christopher David Ramos

Theses and Dissertations

This work is a compilation and analysis of ultracool dwarfs (UCDs) and brown dwarfs within 25 parsecs. It supplements the work of Stauffer et al. [2010] who updated the reputable and widely relied upon Third Catalog of Nearby Stars [Gliese & Jahreiß 1991] with revised coordinates and cross-matched each object with the 2MASS point source catalog [Cutri et al. 2003]. I began by incorporating newly discovered (post 1991) cool companions to Gliese-Jahreiß stars that had been previously undetectable. I then expanded the compilation to include isolated UCDs and other nearby systems with at least one UCD component. Multiple systems are …

This study consists of two phases; first, a mesocosm experiment investigating fertilizer application rates (mg P/L) in relation to potential sunfish growth, and second, a replicated pond experiment consisting of four treatments to simulate commonly used enhancement strategies. Mesocosm experiment showed a peak of sunfish growth at the 0.6 mg P/L level and …

Probing Protein And Organothiol Interactions With Gold Nanoparticles, Karthikeshwar Vangala

Theses and Dissertations

Proteins and organothiols are known for their high binding affinity to noble metal surface including gold nanoparticles (AuNPs). Numerous reports have been dedicated to AuNP interaction with protein or organothiol alone. Competitive protein and organothiol (OT) interaction is, however, mostly an unexplored area. The research reported here focused on developing a fundamental understanding of sequential and simultaneous protein and organothiol interaction with AuNPs in which protein and OT are added either simultaneously or sequentially into the colloidal AuNP solutions. In studies of OT interactions with bovine serum albumin (BSA) stabilized AuNPs, we found that the protein coating layer is highly …

Evaluation Of Wildrye (Elymus Sp.) As A Potential Forage And Conservation Planting For The Southeastern United States, Jason Brett Rushing

Theses and Dissertations

In the southeastern United States, there is a need for a native, cool-season grass component for restoring and reclaiming grasslands and providing quality forage for livestock. Experiments were conducted on southeastern wildrye [Elymus glabriflorus (Vasey) Scribn. & C.R. Ball] to assess agronomic parameters, and establish a base of information for use in future research and breeding programs. Optimal germination requirements (temperature, light, pH, and physical dormancy) were evaluated. Our data suggests that for southeastern wildrye, the optimal temperature required for germination is between 15 and 20oC. Light treatments (constant dark, constant light, short day, and long day) did not influence …

Examining Public Administrators' Perceptions Of Welfare Policy Performance, Elizabeth D. Evans

Theses and Dissertations

Efforts to meet the needs of poverty stricken Americans have resulted in the passage of numerous federal and state policies. Current Temporary Assistance for Needy Families (TANF) policy emphasizes sharing the responsibility for meeting citizens’ needs through partnerships with those in poverty. Such reforms challenge local administrators to define and assess the terms of welfare policy reform success. This study’s adaptation of the theory of positionality examines how position in public organizations can inform employees’ views of welfare policy performances. Specifically, it seeks to determine if the type of administrative responsibility and interaction (positionality) with citizens leads to differing views …

Genomic And Functional Analysis Of Next-Generation Sequencing Data, Philippe Chouvarine

Theses and Dissertations

Advances in next-generation sequencing (NGS) technologies have resulted in significant reduction of cost per sequenced base pair and increase in sequence data volume. On the other hand, most currently used NGS technologies produce relatively short sequence reads (50 - 150 bp) compared to Sanger sequencing (~700 bp). This represents an additional challenge in data analysis, because shorter reads are more difficult to assemble. At this point, production of sequencing data outpaces our capacity to analyze them. Newer NGS technologies capable of producing longer reads are emerging, which should simplify and speed up genome assembly. However, this will only increase the …

Evaluating The Role Of Environmental Stressors And Sensitive Parenting On The Emergence Of Behavior Problems During Early Childhood, Brenna Sapotichne

LSU New Orleans Theses and Dissertations

Repeatedly, parenting quality has been shown to affect children’s level of behavior problems during early childhood (e.g., Bayer, Sanson, & Hemphill, 2006; Shaw, Gilliom, Ingoldsby, & Nagin, 2003). However, the parent-child relationship exists within a broader social context (Bronfenbrenner, 1986). Therefore, social contextual stressors such as financial strain, neighborhood danger, and residential overcrowding may affect children’s adjustment through parenting. Based on The Family Stress model (Conger & Elder, 1994), the current study tests the theory that sensitive parenting mediates the relationship between these three environmental stressors (i.e., financial strain, neighborhood danger, and residential overcrowding) and children’s behavior problems from ages …

The Feasibility Of Closing Vehicle Crossings Along St. Charles Avenue: A Study Of Transit Safety And Performance, Vivek B. Shah

LSU New Orleans Theses and Dissertations

The St. Charles streetcar is an important transit line in the city of New Orleans, with about 65,000 people living within a ½ mile walking distance from it. However, the line experiences a very high streetcar/automobile crash rate due in large part to the large number of grade vehicle crossings over the tracks that lack signalization. Through traffic modeling, the closure of many of these vehicle crossings and the diversion of automotive traffic to the remaining, signalized crossings is analyzed to determine traffic impacts on street network. The result is a modest increase in traffic, about 7-8%, at the remaining …

The Effects Of Intracerebroventricular Leptin On Milk Availability In Lactating Rats, Brittany Lynita Moore

Electronic Theses and Dissertations

Reports have linked energy balance along with adipocyte derived leptin action to improved fertility. Recent evidence indicates that leptin hormone is present in breast milk and leptin receptors are well expressed in mammary epithelial cells. The hypothesis that insufficiency of leptin restraint in the hypothalamus may underlie infertility in rodents and the failure of lactating breast to express adequate amount of milk was tested. Female Sprague-Dawley rats were injected leptin through intracerebroventricular cannulation (ICVC) of the third ventricle. Female rats were mated with stud males and observed throughout gestation. Compared to the control groups, leptin treatment increased prolactin levels in …

Withstanding Cruel Teasing: Does Dispositional Mindfulness Fortify Target Immunity?, Ruth Catherine Lewis

Electronic Theses and Dissertations

Cruel teasing can be pernicious for targets' psychological health. In this thesis I examined the extent to which trait mindfulness might mitigate the negative psychological effects associated with cruel teasing. Correlation results confirmed cruel teasing history related significantly and directly, and mindfulness inversely, to poorer psychological health. Moderated regression analyses confirmed that among targets of frequent cruel teasing those with high levels of mindfulness did not evidence the detrimental psychological effects as did those low in mindfulness. Subsequent moderated regression analyses with cruel teasing history, mindfulness, and sexual identity status suggest that when people are low in mindfulness cruel teasing …

Connotational Subtyping And Runtime Class Mutability In Ruby, Ian S. Dillon

Electronic Theses and Dissertations

Connotational subtyping is an approach to typing that allows an object's type to change dynamically, following changes to the object's internal state. This allows for a more precise representation of a problem domain with logical objects that have variable behavior. Two approaches to supporting connotational subtyping in the Ruby programming language were implemented: a language-level implementation using pure Ruby and a modification to the Ruby 1.8.7 interpreter. While neither implementation was wholly successful the language level implementation created complications with reflective language features like self and super and, while Ruby 1.8.7 has been obsoleted by Ruby 1.9 (YARV), the results …
