Outside Things, Jacob Sorenson
Outside Things, Jacob Sorenson
Theses and Dissertations
My thesis is a description of the issues encountered during the process of research and construction of the objects leading to, and consisting of, the work shown in Outside Things. The work is my attempt to gain personal insight into the complicated relationship between nature and culture. Through abstract furniture objects, floral patterns, and robots I explore the relationship between actual landscape and the constructed man-made bio-mimicry that convolutes the definition of Nature.
Craft Cyborg, Laina Seay
Craft Cyborg, Laina Seay
Theses and Dissertations
By merging the ancient associations that clay has with the human form and prosthetic science I question the relevancy and role of the human body in the future. As prosthetics heighten the awareness of the body through absence these additive limbs further this relevancy by presence. With greater advances in genetic engineering and plastic surgery biology will no longer dominate and these ridged clay extensions could become flesh.

Analysis Of The Mechanism By Which Ykl-40 Promotes Glioma Cell Migration, Bahiya Osrah
Analysis Of The Mechanism By Which Ykl-40 Promotes Glioma Cell Migration, Bahiya Osrah
Theses and Dissertations
This thesis elucidates the crucial role of YKL-40 in enhancing glioma cell migration and invasion in vitro. Increased levels of YKL-40 are specifically associated with the increased invasive capacity of glioma multiforme (GBM) tumors and lower survival rate of GBM patients. In order to examine the effects of YKL-40 on the migration and invasion of GBM cells, we overexpressed YKL-40 in three different glioma cell lines. The overexpression of YKL-40 significantly enhanced glioma cells migration and invasion in vitro and also increased ERK phosphorylation, which is believed to enhance glioma cell survival, and invasiveness. Although receptors for YKL-40 are still …
Prenatal Alcohol Exposure Reduces Dendritic Spine Density Across Sensory Cortices, Francis Oppong
Prenatal Alcohol Exposure Reduces Dendritic Spine Density Across Sensory Cortices, Francis Oppong
Theses and Dissertations
Dendritic spines are the major site of excitatory synapses in cortex, and factors that reduce dendritic spine numbers will produce serious cortical processing deficits, such as has been demonstrated for mental retardation and other psychiatric disorders. Prenatal alcohol exposure also has detrimental effects on brain development that lead to Fetal Alcohol Spectrum Disorder (FASD), which results in reduction of dendritic spine numbers in the hippocampus, prefrontal cortex and somatosensory cortex. FASD also is associated with temporal processing disorders involving sequential auditory stimuli that would be processed in auditory cortical areas. However, it is unknown if the reduction of spine density …

Analysis Of Nfi-X3 And Stat3 Interaction And Its Functions, Etsegenet Tizazu
Analysis Of Nfi-X3 And Stat3 Interaction And Its Functions, Etsegenet Tizazu
Theses and Dissertations
YKL-40 is a secreted protein that is highly up-regulated in malignant glioblastoma (GBM). Its expression is correlated with the invasive nature of GBMs and poor diagnosis of patients (Nigro et al., 2005). Previous research has shown that in astrocytes and GBM cells, YKL-40 expression is regulated by two transcription factors, NFI-X3 and STAT3, which form a complex with each other (Singh et al., 2011). Here, we show that the N-terminal domain of NFI-X3 is sufficient and required for its interaction with STAT3. We also show that the DNA-binding domain of NFI-X3 is required to induce YKL-40 expression. Thus, the interaction …
Computational Modeling Of Mulitsensory Processing Using Network Of Spiking Neurons, Hun Ki Lim
Computational Modeling Of Mulitsensory Processing Using Network Of Spiking Neurons, Hun Ki Lim
Theses and Dissertations
Multisensory processing in the brain underlies a wide variety of perceptual phenomena, but little is known about the underlying mechanisms of how multisensory neurons are generated and how the neurons integrate sensory information from environmental events. This lack of knowledge is due to the difficulty of biological experiments to manipulate and test the characteristics of multisensory processing. By using a computational model of multisensory processing this research seeks to provide insight into the mechanisms of multisensory processing. From a computational perspective, modeling of brain functions involves not only the computational model itself but also the conceptual definition of the brain …
Meaning Maintenance In Close Relationships, Daryl R. Van Tongeren
Meaning Maintenance In Close Relationships, Daryl R. Van Tongeren
Theses and Dissertations
The human motivation for meaning has been a longstanding topic of inquiry, and recent research has begun to investigate how individuals maintain a sense of meaning in life. Given the importance of social connectedness in human life, as well as the role of relationships in providing a sense of meaningfulness, the present investigation explored meaning maintenance within the domain of close relationships. Specifically, a theoretical model for interpersonal meaning maintenance is presented, which proposes that moral actions—particularly forgiveness—are oriented toward restoring relationship quality, and, in turn, meaning in life, in the wake of interpersonal transgressions. The tenets of this model …
Coherent Turbulence: Synthesizing Tree Motion In The Wind Using Cfd And Noise, Anthony Frank Selino
Coherent Turbulence: Synthesizing Tree Motion In The Wind Using Cfd And Noise, Anthony Frank Selino
Theses and Dissertations
Animating trees in wind has long been a problem in computer graphics. Progress on this problem is important for both visual effects and biomechanics and may inform future work on two-way coupling between turbulent flows and deformable objects. Synthetic turbulence added to a coarse fluid simulation has been used to produce convincing animations of turbulent flows, but only considers one-way coupling between fluid and solid. We produce accurate animations of tree motion by creating a two-way coupling between synthetic turbulence and semipermeable proxy geometry. The resulting animations exhibit global wind sheltering effects and branch tips have motion paths which match …
Turning To The Bottle For Answers: Identifying Racial Differences In Predictors Of Risk Drinking Among College Women, Melody Mickens
Turning To The Bottle For Answers: Identifying Racial Differences In Predictors Of Risk Drinking Among College Women, Melody Mickens
Theses and Dissertations
Epidemiological data suggest that alcohol use and related problems have increased among college women. The current study examined psychosocial predictors of risk drinking in a sample of college women (N=360), whether race moderated this relationship. Potential predictors included: daily smoker; premenstrual syndrome (PMS) symptom severity; age at first alcohol use, negative affect, parental history of alcohol problems and minority status. Analyses found that somatic PMS symptom severity score, age of first alcohol use, daily smoking, age of first alcohol use and non-minority status were related. Findings suggest that minority group membership was associated with low risk drinking, while somatic PMS …

Cumulative Risks To Eastern Oysters, Crassostrea Virginica In The James River, Va, Vrushali Lele
Theses and Dissertations
In an effort to apply Cumulative Risk Assessment (CRA) as developed by the U.S. EPA, the present study investigates the cumulative risks to Eastern oysters due to multiple stressors such as salinity, temperature and oxygen and carbon dioxide. I also compared the effectiveness of the Hazard Quotient Method (HQ) in CRA. Ambient conditions in the James River, VA were obtained from the Virginia DEQ database and respiratory responses were estimated using values from the literature. The multiple environmental stresses are evaluated using a probabilistic analysis that combines the environmental conditions. It was concluded that salinity was the most influential stressor …
Defining The Bacterial Flora Of Periodontal Pockets In Chronic Periodontitis Patients, Rafael Rodriguez
Defining The Bacterial Flora Of Periodontal Pockets In Chronic Periodontitis Patients, Rafael Rodriguez
Theses and Dissertations
PURPOSE: The purpose of this study is to describe the subgingival bacterial biodiversity in untreated chronic periodontitis patients through the use of next generation 16S rRNA molecular analysis, and to determine similarities or differences between deep and shallow pockets within the same patients. METHODS: The analysis involved paired subgingival plaque samples from 24 subjects diagnosed with Generalized Moderate to Severe Chronic Periodontitis. One sample was selected from a single site having a probing depth >5 mm (i.e. Deep Site), and the other from a site with a probing depth <3mm (i.e. Shallow Site) within each subject. Bacterial DNA amplification of the V4-V6 region of the 16S rRNA was performed. The amplicons were sequenced via 454 Roche Genome Sequencer FLX System. The identified sequences were evaluated, and then compared to calculated false discovery rates. RESULTS: A total of 119 independent microbial genera were identified within the samples analyzed. Seven genera were identified to be statistically significant (p<0.05) in their association to deep or shallow sites following t-test and boot strap randomization: Actinomyces (p=0.004), Methylobacterium (p=0.028), Veillonella (p=0.028), and Rothia (p=0.038), and Streptococcus (p=0.033) in Shallow sites; while Mycoplasma (p=0.007) and Fusobacterium (p=0.016) were associated with deep sites. However, taking into account the calculated false discovery rates, it is suggested that none of the 119 microbial genera identified in this study were significantly associated with either deep nor shallow sites. CONCLUSION: The microbial genera identified within this study to be associated with deep and shallow sites follows the traditional pattern anticipated from the literature. However, the calculated false discovery rates suggest that these results may have occurred by chance and not due to a true difference.
Developing A Remote Sensing Algorithm For Deriving Soil Moisture From Spectral Reflectance, Santosh Rijal
Developing A Remote Sensing Algorithm For Deriving Soil Moisture From Spectral Reflectance, Santosh Rijal
Theses and Dissertations
Wet weather cycle since 1993 has brought ground water level closer to the surface of the soil in many areas in the Red River Valley (RRV) of the North basin. Many farmers have to delay spring plantation or autumn harvest due to excessive moisture in', their farmland. In such case, it becomes increasingly important to have timely and accurate information on the soil moisture conditions. Conventional soil moisture measurement techniques are point-based that results in poor spatial representation of soil moisture. Remote sensing techniques offer many potential advantages over traditional means such as repetitive coverage and areal representation. The objective …

Nursing equipment must be cleaned and disinfected properly between patients and proper hand hygiene should be done to decrease health-care associated infections in the home and community setting. A review and synthesis of the most current literature was done by searching the Cumulative Index to Nursing and Allied Health literature (CINAHL), Cochrane Database, Google Scholar™ and Google™ databases. Key words include infection control, home visits, public health, cleaning, home health, equipment, disinfectants and combinations of those words. Tools were created for dissemination to nurses providing care in …
Theory-Derived Approaches To Behavioral And Psychological Symptoms Of Dementia, Bethany Speecy
Theory-Derived Approaches To Behavioral And Psychological Symptoms Of Dementia, Bethany Speecy
Theses and Dissertations
As the world's population ages, the prevalence of Alzheimer's disease and other conditions that cause dementia is expected to increase. Although there is some awareness of the dangers of psychotropic drugs used to address behavioral and psychological symptoms of dementia, all too often these agents continue to be used as first-line treatment. Nurses need to be cognizant of safer, efficacious, holistic nonpharmacological approaches and utilize these in an individualized, systematic manner. Two mid-range nursing theories, the Need-Driven Dementia-Compromised Behavior model and the Progressively Lowered Stress Threshold model, provide conceptual frameworks for nonpharmacological interventions. This paper examines these models and describes …

Two culture lines, MA, and NA were isolated within our laboratory and could grow in secondarily treated wastewater with no additional nutrients. The maximum biomass concentration of MA in batch culture was 0.860 g/L and the sum of glucose and xylose was …
A Minimum Spanning Tree Based Clustering Algorithm For High Throughput Biological Data, Harun Pirim
A Minimum Spanning Tree Based Clustering Algorithm For High Throughput Biological Data, Harun Pirim
Theses and Dissertations
A new minimum spanning tree (MST) based heuristic for clustering biological data is proposed. The heuristic uses MSTs to generate initial solutions and applies a local search to improve the solutions. Local search transfers the nodes to the clusters with which they have the most connections, if this transfer improves the objective function value. A new objective function is defined and used in the heuristic. The objective function considers both tightness and separation of the clusters. Tightness is obtained by minimizing the maximum diameter among all clusters. Separation is obtained by minimizing the maximum number of connections of a gene …

Agricultural Conservation Buffers For Breeding Grassland Birds In Eastern Mississippi, Heidi Lynn Adams
Agricultural Conservation Buffers For Breeding Grassland Birds In Eastern Mississippi, Heidi Lynn Adams
Theses and Dissertations
Periodic disturbance in CP33 habitat buffers is required to maintain early-successional plant communities for grassland birds. However, effects of disturbance on habitat suitability and nesting success of grassland birds are unknown. Furthermore, the grassland bird community and reproductive performance in CP33 habitat buffers may be influenced by the landscape context (e.g., edge habitat, surrounding land cover). My objectives for this study were to determine how periodic disturbance and the agricultural landscape mosaic influence the breeding grassland bird community in buffers, and how these same factors influence grassland bird nesting success and density in buffers. Data collected during line-transect surveys conducted …

Asperger's Syndrome And Learning Strategies: Are Difficulties Due To A Production Deficit Or To A Utilization Deficit?, Miranda Lee Morris
Asperger's Syndrome And Learning Strategies: Are Difficulties Due To A Production Deficit Or To A Utilization Deficit?, Miranda Lee Morris
Theses and Dissertations
This study investigated whether knowledge about memory strategies was impaired in a group of young adults with Asperger’s Syndrome (AS) as compared to a group of young adults without AS. Both groups participated in two tasks, one designed to examine the categorization strategy and one to examine the interactive imagery strategy. Participants with AS showed a production deficit because they were unable to spontaneously produce either strategy to benefit their memory performance. However, the group with AS did not show evidence of a utilization deficit; when they were trained on strategies, they were able to use them effectively both immediately …

Assessment And Prediction Of Streambank Erosion Rates In A Southeastern Plains Ecoregion Watershed In Mississippi, John Jairo Ramirez Avila
Theses and Dissertations
The Town Creek Watershed (TCW) is a representative area of the Tombigbee River Basin and the Southeastern Plains Ecoregion in Mississippi. The principal channel and four main tributaries have been included for several years within the MS Section 303(d) list of waterbodies biologically impaired due to sediment. The TMDL developed for TCW recommended that streams located near cultivated lands, road crossings and construction activities are a priority for streambank and riparian buffer zone restoration and sediment loads reduction. Development of remedial measures and future BMPs within TCW for reducing water quality impairment and downstream dredging costs requires identification of sediment …

Distribution And Management Of Invasive Plant Species In The Ross Barnett Reservoir, Michael Christopher Cox
Theses and Dissertations
A point intercept survey was conducted from 2005 to 2010 on the Ross Barnett Reservoir near Jackson, MS to calculate the frequency of occurrence of all aquatic plant species in the Reservoir. style='mso-spacerun:yes'> Water lotus ( style='mso-bidiont-style:normal'>Nelumbo lutea Willd.) was the native species that occurred most often, while alligatorweed (Alternanthera style='mso-bidiont-style:normal'> philoxeroides [Mart.] Griseb.) occurred most often with regard to non-natives. A logistic regression model indicated that as species richness increases, the probability of observing a non-native species also increases. Herbicide evaluations implied that the chemical imazapyr provided the largest biomass reduction in alligatorweed over a twelve week period; …
Effect Of Hunting Frequency On Duck Abundance, Harvest, And Hunt Quality In Mississippi, Elizabeth Anne St James
Effect Of Hunting Frequency On Duck Abundance, Harvest, And Hunt Quality In Mississippi, Elizabeth Anne St James
Theses and Dissertations
Waterfowl hunting is important historically, culturally, and economically in Mississippi and North America. I evaluated effect of hunting frequency (2 or 4 days/week) on duck abundance, harvest, and hunters’ perceived quality of their experience on Mississippi Wildlife Management Areas (WMAs). Neither relative abundance nor harvest of all ducks, mallard (Anas platyrhynchos), northern shoveler (A. clypeata), or green-winged teal (A. crecca) differed between experimental hunting frequencies. Duck harvest increased with hours spent afield. Hunters’ perceived quality did not differ between hunting frequencies but was greatest when hunters harvested > 4 ducks/ day and increased with harvest of larger sized ducks. I suggest …
