The Effect Of Doing Good: An Experimental Analysis Of The Influence Of Corporate Social Responsibility Initiatives On Beliefs, Attitudes, And Behavioral Intentions, Cristina Marta Gonzalez

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to further current theory-driven research in public relations by examining the influence of corporate social responsibility (CSR) initiatives on beliefs, attitudes, and behavioral intentions. Specifically, CSR initiatives identified by Kotler and Lee (2005) were tested using Fishbein and Ajzen’s (1975, 2005) theory of reasoned action to determine their influences on individual’s belief, attitudes, and behavioral intentions toward an organization and its products. This area of inquiry is particularly relevant for public relations scholars and practitioners since creating awareness of CSR practices among key stakeholders requires accurate and timely communication.

Isolation Of Haloalkaliphilic Bacteriophages From Soap Lake, Washington, Audrey Oakley

Undergraduate Research Conference at Missouri S&T

Soap Lake, a meromictic halo alkaline lake located in central Washington State, provides a habitat for many unique types of microbiotas. Due to its meromictic quality, the layers of the lake do not mix, instead separating to produce distinct environments within the lake, causing a variance in microbiota from layer to layer. Though viral studies have been conducted on halo alkaline lakes, only a few viruses have been isolated and studied. The focus of this study was to investigate the types of viruses found in Soap Lake. Haloalkaliphilic bacteriophages were found to be present in Soap Lake. This viral community …

Ftsh Gene Family Identification, David Calcara

Undergraduate Research Conference at Missouri S&T

Gene family research is an important area of genetics which can help to identify evolutionary lines. Starting with the FtSH gene family in Arabidopsis, a well-studied relative of a well-studied relative of Glycine max, with the ultimate goal of finding members of the gene family in G. max, computer programs were used to compare the genes in Arabidopsis to more closely related plants. These were then compared to G. max ESTs, which were assembled into contigs where ORFs were identified. The contigs were compared and the EST sources for the best contigs were identified. Overall, five members of the FtSH …

Assessment Of In Vivo Bone Formation Using Porous, Glass Scaffolds Seeded With Mesenchymal Stem Cells, Wesley Glick

Undergraduate Research Conference at Missouri S&T

The purpose of this investigation was to compare two different porous scaffolds composed of silica based bioactive glass in their ability to facilitate bone growth in vivo when seeded with mesenchymal stem cells. Companion scaffolds were also used without seeding as a control. One scaffold was constructed entirely of 45S5, while the other was a 70/30 blend of 45S5 and 13-93. These scaffolds were implanted underneath the skin on the backs of young, healthy rats. After recovery, the scaffolds were fixed and processed for analysis. The samples were infiltrated with methyl methacrylate, which was polymerized. Sections were made, ground, polished, …

Characterization Of Autoinducer Production In Bradyrhizobium Japonicum, Ashley Boudria

Undergraduate Research Conference at Missouri S&T

Quorum sensing allows bacteria to communicate with each other and coordinate their behavior with their surroundings. This communication uses autoinducers, such as Acyl-homoserine lactones (AHLs), which is produced and secreted by several strains of Bradyrhizobium japonicum. This study characterizes the production of AHL in specific strains of B. japonicum and describes the relationship between AHL production and a supposed AHL synthase gene in the B. japonicum genome. Polymerase Chain Reaction (PCR) was performed on various bacterium strains to amplify the synthase gene. Extraction of AHLs from B. japonicum culture supernatants were used to analyze AHL production using thin-layer chromatography (TLC). …

Radiotolerance Of Microorganisms Isolated From The Umr Reactor, Jacob Elmer

Undergraduate Research Conference at Missouri S&T

The surface of Mars is exposed to high levels of solar and galactic cosmic ray irradiation. Thus, microorganisms that could possibly survive in the shallow subsurface of Mars would likely be radio tolerant. To better understand microorganisms that might reside in this environment of Mars, a number of isolates were obtained from a gamma-radiation source {¹³⁷Cs) located on the UMR campus. Radiation sensitivity assays were performed on the isolates as well as on the common bacterium, E. coli. The E. coli did not survive exposures of 100 to 200 Gy while the isolate designated 18-1 survived. Another isolate, …

Identification Of An Uncharacterized Rna-Binding Protein That Affects Cytokinesis In Saccharomyces Cerevisiae., Amy Hunt

Undergraduate Research Conference at Missouri S&T

Cytokinesis is the physical separation of the cytoplasm after mitosis that results in two daughter cells. This is accomplished by the use of a contractile ring composed primarily of actin and myosin. This project used gene knockout techniques in S. cerevisiae to determine the effect a gene has on cytokinesis. We used one-step PCR-mediated gene replacement to delete an uncharacterized open reading frame (ORF) that has been identified in a genomic screen as interacting with the cytokinesis protein Hof1. Deletion of this ORF, YGR250C, resulted in a cytokinesis defect. The gene deletion resulted in 12% of the cells exhibiting a …

Novel Method To Express Functional Epitope-Tagged Gpcrs, Amanda Sutterer

Undergraduate Research Conference at Missouri S&T

Epitope tagging of G-protein coupled receptors (GPCRs) typically involves the addition of a specific antigenic amino acid sequence (e.g., hemagglutinin) to the N-terminus, a region not involved in receptor ligand binding or signal transduction functions. However, with certain GPCRs this method fails due to posttranslational cleavage of the N-terminal tag or inhibition of membrane isertion. To overcome this, we modified a cloning vector so that it would insert an artificial cleavage site at the N-terminus of the protein before the epitope. This ensures that a functional receptor will be expressed and properly inserted into the membrane. Clones of an opioid …

A Protocol For 3d Reconstructions From Reduced-Quality Serial Histological Sections, Marshall Mcdaniel

Undergraduate Research Conference at Missouri S&T

Computer-generated 3D reconstructions of anatomy allow the examination of minute and internal structures that cannot be visualized using traditional methods. Digital reconstructions are generated from many sources, including magnetic resonance imaging, computed tomography, and histological serial sections. Of these, serial sections provide the most information, but are difficult to generate because of deformation and misalignment. Protocols to eliminate inconsistencies in a serial section stack could result in informative reconstructions generated efficiently and inexpensively. I describe a protocol I developed to construct 3D visualizations from reduced-quality serial sections. Using this technique, I created a reconstruction of the vertebral column of the …

Cytokinesis Defects In Budding Yeast, Katherine Stockstill

Undergraduate Research Conference at Missouri S&T

Budding yeast are a very good research organism, because they are very similar to humans in many ways. One of the problems with budding yeast is that there are many genes that are uncharacterized, and it is not known what their cellular function is or what their functional role is. One way to study gene function is to knock out the gene. The purpose of knocking genes out is because they are uncharacterized genes that have been identified in genomic screens as interacting with cytokinesis proteins. Cytokinesis is the division of a cell into two daughter cells. Our research lab …

Nanocomposite Materials For Hydrogen Storage, Devang Dasani

Undergraduate Research Conference at Missouri S&T

Hydrogen fuels have been studied as a potential alternative energy source though the storage of hydrogen has not been an easy task. One answer to increase storage capacity is to introduce well dispersed metal nanoparticles onto the surface of the nanotubes to alter the surface chemistry of the nanotubes. It was shown that plain sonochemically treated nanotubes had an ambient (25°C) hydrogen uptake of 0.75%, while nanotubes doped with 5.3 nm diameter Pd particles gave an ambient uptake of 3.5%. Initially a broad range of pH between 4 and 10 was used to determine the effect, if any, of pH …

Phosphorus Uptake Mechanisms In Missouri Streams, Will Granich

Undergraduate Research Conference at Missouri S&T

Excess nutrients affect many natural ecosystems and lead to imperilment of ecosystem integrity. Although nutrient uptake in streams has received growing attention in recent years, we still have little quantitative information on the specific characteristics of streams that affect uptake rates. My research included combining experimental (using artificial streams) and observational (measuring uptake in whole streams) approaches to understand specific controls on phosphorus uptake in streams. Phosphorus was chosen because it is one of the primary nutrients that enter water systems through agricultural runoff. This research attempted to quantify the response of nutrient uptake from the addition of limestone and …

Covariate Adjustment In Randomized Trials With Binary Outcomes: Targeted Maximum Likelihood Estimation, Kelly L. Moore, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

Covariate adjustment using linear models for continuous outcomes in randomized trials has been shown to increase efficiency and power over the unadjusted method in estimating the marginal effect of treatment. However, for binary outcomes, investigators generally rely on the unadjusted estimate as the literature indicates that covariate-adjusted estimates based on logistic regression models are less efficient. The crucial step that has been missing when adjusting for covariates is that one must integrate/average the adjusted estimate over those covariates in order to obtain the marginal effect. We apply the method of targeted maximum likelihood estimation (MLE), as presented in van der …

Haplotype Association Between Haptoglobin (Hp2) And Hp Promoter Snp (A-61c) May Explain Previous Controversy Of Haptoglobin And Malaria Protection, Sharon E. Cox, Conor Doherty, Sarah H. Atkinson, Chidi V. Nweneka, Anthony J.C. Fulford, Hala Ghattas Ph.D., Kirk A. Rockett, Dominic P. Kwiatkowski, Andrew M. Prentice

Faculty Publications

Background.

Malaria is one of the strongest recent selective pressures on the human genome, as evidenced by the high levels of varying haemoglobinopathies in human populations-despite the increased risk of mortality in the homozygous states. Previously, functional polymorphisms of Hp, coded by the co-dominant alleles Hp1 and Hp2, have been variously associated with several infectious diseases, including malaria susceptibility.

Methodology/Principal Findings.

Risk of a clinical malarial episode over the course of a malarial transmission season was assessed using active surveillance in a cohort of Gambian children aged 10-72 months. We report for the first time that the major haplotype for …
