Explaining Combat Related Posttraumatic Stress Disorder: An Integrated Mental Illness And Military Process Model, Mandi F. Deitz

Electronic Theses and Dissertations

The purpose of the current study was to examine a process model of combat-related and mental-illness related processes that explain increased likelihood of Posttraumatic Stress Disorder (PTSD). This dissertation proposed the development of PTSD may occur due to cultural, social, and self-related pathways associated with veterans’ dual encounters with combat (i.e., severity) and mental illness symptoms. Participants were 195 military veterans recruited from multiple sites and strategies to maximize sample size and representation. Participants were asked to complete several self-administered assessment inventories, including: the Posttraumatic Stress Disorder Checklist-Military, the Trauma Symptom Checklist, the Combat Experiences scale, the Self-Stigma of Mental …

Analyses Of 2002-2013 China’S Stock Market Using The Shared Frailty Model, Chao Tang

Electronic Theses and Dissertations

This thesis adopts a survival model to analyze China’s stock market. The data used are the capitalization-weighted stock market index (CSI 300) and the 300 stocks for creating the index. We define the recurrent events using the daily return of the selected stocks and the index. A shared frailty model which incorporates the random effects is then used for analyses since the survival times of individual stocks are correlated. Maximization of penalized likelihood is presented to estimate the parameters in the model. The covariates are selected using the Akaike information criterion (AIC) and the variance inflation factor (VIF) to avoid …

An Agent-Based Model Of Ant Colony Energy And Population Dynamics: Effects Of Temperature And Food Fluctuation, Guo Xiaohui

Electronic Theses and Dissertations

The ant colony, known as a self-organized system, can adapt to the environment by a series of negative and positive feedbacks. There is still a lack of mechanistic understanding of how the factors, such as temperature and food, coordinate the labor of ants. According to the Metabolic Theory of Ecology (MTE), the metabolic rate could control ecological process at all levels. To analyze self-organized process of ant colony, we constructed an agent-based model to simulate the energy and population dynamics of ant colony. After parameterizing the model, we ran 20 parallel simulations for each experiment and parameter sweeps to find …

An Examination Of Risk And Protective Factors For Suicidal Behavior In A Low-Income, Underserved Primary Care Sample, Kristin L. Walker

Electronic Theses and Dissertations

Suicidal behavior, including ideation and attempts, is a significant public health problem. Due to the complexity of suicidal behavior, it is necessary to consider an array of factors that could serve as risk and protective factors. Previous research has shown that deficits in social problemsolving ability are associated with increased risk for suicidal ideation and attempts; conversely, problem solving strengths are associated with reduced risk. This dissertation project, consisting of 3 individual manuscripts, was designed to explore the relationship between social problemsolving ability and suicidal behavior in low-income primary care patients. Furthermore, additional constructs including health related quality of life, …

The Effects Of Working Memory On Brain-Computer Interface Performance, Samantha A. Sprague

Electronic Theses and Dissertations

Amyotrophic lateral sclerosis and other neurodegenerative disorders can cause individuals to lose control of their muscles until they are unable to move or communicate. The development of brain-computer interface (BCI) technology has provided these individuals with an alternative method of communication that does not require muscle movement. Recent research has shown the impact psychological factors have on BCI performance and has highlighted the need for further research. Working memory is one psychological factor that could influence BCI performance. The purpose of the present study is to evaluate the relationship between working memory and brain-computer interface performance. The results indicate that …

Parallel Identities: Southern Appalachia And The Southern Concepts Of Gender During The American Civil War, Maegan K. Harrell

Electronic Theses and Dissertations

Southern concepts of gender influenced Appalachian society throughout the antebellum and Civil War eras. Concepts of masculinity and femininity, including “the cult of true womanhood” and Southern manhood, shifted and broaden throughout the South due to wartime stressors. Appalachians adjusted these gender roles in order to survive chaos and turmoil in their region. The brutal political and community divisions, high rates of desertion, guerilla warfare, and threats of invasion in the mountain regions intensified these concepts of gender. Southern constructions of gender molded the Appalachian experience of war but the high level of conflict strengthened these new roles as a …

Streptomyces are known to produce a large variety of antibiotics and other bioactive compounds with remarkable industrial importance. Streptomyces sp. COUK1 was found as a contaminant on a plate in which Rhodococcus erythropolis was used as a test strain in a disk diffusion assay and produced a zone of inhibition against the cultured R. erythropolis. The identity of the contaminant was confirmed as Streptomyces through 16S rRNA sequencing. This Streptomyces produces a strong inhibitory compound in different growth media. A culture extract from inorganic salts starch agar was found to be very active; producing a large zone of inhibition …

Health-Related Quality Of Life And Suicidal Behaviors In Primary Care Patients: Conditional Indirect Effects Via Interpersonal Needs And Depressive Symptoms, Catherine Rowe

Electronic Theses and Dissertations

Suicide is a public health problem and complex relationships exist between intrapersonal suicide risk factors and interpersonal risk factors. Health-related quality of life (HRQL) may interact with difficulties with interpersonal relationships and psychopathology. We examined thwarted interpersonal needs and depressive symptoms as potential mediators on the association between HRQL and suicidal behaviors. It was hypothesized that thwarted interpersonal needs would mediate the association between HRQL and suicidal behavior, and that this mediating effect would be dependent on the moderating effect of depressive symptoms. It was hypothesized that thwarted interpersonal needs and then depressive symptoms would sequentially mediate the association between …

Chitosan-Cellulose Composite For Wound Dressing Material. Part 2. Antimicrobial Activity, Blood Absorption Ability, And Biocompatibility, April L. Harkins, Simon Duri, Luther C. Kloth, Chieu D. Tran

Clinical Lab Sciences Faculty Research and Publications

Chitosan (CS), a polysaccharide derived from chitin, the second most abundant polysaccharide, is widely used in the medical world because of its natural and nontoxic properties and its innate ability for antibacterial and hemostasis effects. In this study, the novel composites containing CS and cellulose (CEL) (i.e., [CEL + CS]), which we have previously synthesized using a green and totally recyclable method, were investigated for their antimicrobial activity, absorption of anticoagulated whole blood, anti-inflammatory activity through the reduction of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), and the biocompatibility with human fibroblasts. The [CEL + CS] composites were found to …

Those Doggone Police: Insufficient Training, Canine Companion Seizures, And Colorado’S Solution, Kaylan E. Kaatz

San Diego Law Review

This Comment advocates that California adopt Colorado’s Dog Protection Act or a similar measure mandating police training for dog interactions and implementing specific procedures by law enforcement agencies to reduce dog shootings by police. With the increasing occurrence and coverage of police dog shootings, the need for more adequate law enforcement training on animal encounters is ever present. Additional training, as recently mandated by the Colorado legislature, would minimize police dog shootings. It would also help clarify the applicability of 42 U.S.C. section 1983, the federal statute permitting recovery for the loss of a dog due to a police shooting. …

Assessment Of Nitrifying Bacteria In Massard Plant Using Molecular Tools, Jennifer Puanani Holmes-Smith

Civil Engineering Undergraduate Honors Theses

The discharge of nutrients (such as nitrogen and phosphorus) from wastewater treatment plants (WWTP) has become an increasingly important issue in the United States. Ammonia (NH3) is a common contaminant found in domestic wastewater and agricultural runoff. It can cause toxicity in fish if left untreated. The United States Environmental Protection Agency (EPA) recommends low national criteria for ammonia limits in freshwater. With these greater restrictions, ammonia-nitrogen limit compliance (5 mg/L) has become an issue at the Massard WWTP in Fort Smith, Arkansas. The purpose of this research is to assess the ammonia removal in the Massard WWTP in order …

Nerve Fiber Diameter Measurements Using Hematoxylin And Eosin Staining And Brightfield Microscopy To Assess The Novel Method Of Characterizing Peripheral Nerve Fiber Distributions By Group Delay, Jorge Arturo Vazquez

Master's Theses

Peripheral neuropathies are a set of common diseases that affect the peripheral nervous system, causing damage to vital connections between various parts of the body and the brain and spinal cord. Different clinical conditions are known to selectively impact various size nerve fibers, which often makes it difficult to diagnose which peripheral neuropathy a patient might have. The nerve conduction velocity diagnostic test provides clinically useful information in the diagnosis of some peripheral neuropathies. This method is advantageous because it tends to be minimally invasive yet it provides valuable diagnostic information. However, this test does not determine characteristics of peripheral …

Treatment Of Nitrogen Oxides By Chlorella Vulgaris Algae In Photobioreactors, Steven Shihady

Master's Theses

The effectiveness of algae to treat NO₂and NO in simulated flue gas was tested using Chlorella vulgaris in photobioreactors (PBRs) using NO_xconcentrations between 30 ppm to 780 ppm. NO_xdissolved and reacted in water to form NO₃^-and NO₂^-in the PBR growth medium, providing a nitrogen source that the algae readily assimilated for cell synthesis. Three 20-L photobioreactors were inoculated with a pure culture of C. vulgaris prepared in Bristol growth medium and algae were grown in the PBRs at 25°C and pH of 7.0 in a modified Bristol medium …

Behavioral And Hormonal Flexibility Across Light Environments In Guppies (Poecilia Reticulata), Julia C. Walz

Master's Theses

Behavior may be dramatically influenced by changing environments, and differences in light intensity environments may have important behavioral consequences. One approach to understanding changes in behavior is by studying behavioral syndromes, suites of correlated behaviors reflecting between individual consistencies in behavior expressed within a behavioral situation (e.g., correlations between antipredator behaviors in different habitats), or across behavioral contexts (e.g., correlations among feeding, antipredator, or mating behavior) (Sih et al. 2004a). Guppies (Poecilia reticulata) provide a great model system to study behavior. Guppies are small, freshwater tropical fish that inhabit still pools in swift-flowing streams, and the backwaters of small rivers …

Delineating Wetlands In Serpentinitic Soils, Ariel Nikole Namm

Master's Theses

Wetlands serve an important ecological and functional role in the environment. In order to protect wetlands from degradation, the determination of wetland hydrology, hydrophytic vegetation, and hydric soils is necessary. Soils formed from serpentine parent material on hillside slump blocks do not meet any of the current morphological Field Indicators of Hydric Soils. Although these areas seem to be wetlands based on wetland hydrology and hydrophytic vegetation, there is no approved hydric soil indicator that includes the properties exhibited by serpentinitic soils on these landscapes. The objectives of this research were: (1) to examine soil chemical, physical, and morphological properties …

Assessment Of Microbial Biodegradation Of Mixed Soil Contaminants At The Santa Susan Field Laboratory Using Trflp, Qpcr, And Culturing, Kenny William Croyle

Master's Theses

The potential for biodegradation of contaminants in soil was assessed using an array of molecular methods, including terminal restriction fragment length polymorphism (TRFLP), quantitative polymerase chain reaction (qPCR), and traditional culturing techniques combined with sequencing of the 16S or ITS regions of the cultured bacteria and fungi. Soil was collected from the Santa Susana Field Laboratory (SSFL), which was the site of numerous liquid-propulsion rocket engine tests as well as nuclear energy research and development, which led to contamination of the soil with a wide variety of constituents. The contaminants of interest (COIs) at this site include polychlorinated biphenyls (PCBs), …

A Multicultural Nutrition And Culinary Intervention For Middle School Students: Pink And Dude Chefs, Phase 2, Jaime Lynn Lockhart

Master's Theses

The prevalence of adolescent obesity in the United States has more than quadrupled in the past 30 years, growing from 5% to nearly 21% in 12-19 year olds. Although obesity has many interrelated causes, a lack of knowledge and practical skill to prepare healthy food from scratch is an important factor. Research indicates that nutrition and culinary interventions based on behavioral change theories may improve mediators of healthful eating in adolescents.

Pink and Dude Chefs, Phase 2, an eight-week after-school nutrition and culinary intervention targeted towards middle school students in a predominantly low-income, Hispanic community, was developed and evaluated. The …

A Comparison Of Fatigue During Cardiocerebral Resuscitation With Different Compression Rates Among Layperson And Professional Rescuers, Christopher Cassidy

Master's Theses

Quality chest compressions during Cardiopulmonary Resuscitation (CPR) are vital to maintaining adequate perfusion of oxygenated blood to the organs of the body to sustain life. Over the years, the compression rate recommended in Basic Life Support (BLS)/ Advanced Cardiac Life Support (ACLS) protocols for the best possible outcome has risen, and with that increase there are questions regarding rescuer fatigue and the effectiveness of compressions. Layperson and professional rescuers, answering to an emergency, both maintain continuous chest compressions until advanced life support arrives. Depending on the location, this arrival time would most likely be longer than the two minute standard …

A Spatial Analysis Of Changes In Recreational Fishing Pressure On The Central Coast Of California Subsequent To Mpa Implementation, Morgan Ivens-Duran

Master's Theses

Marine Protected Areas (MPAs) are implemented to address a variety of management concerns, including conservation and restoration of fisheries, but few studies assess how MPAs affect regional fishing patterns. Previous research suggests effort will intensify at MPA edges, but few datasets include sufficient pre-implementation data to quantify how MPAs alter fishing effort. We used recreational fisheries data collected by scientific observers aboard Commercial Passenger Fishing Vessels that target nearshore fish species, primarily rockfish. We assessed shifts in the spatial distribution of fishing effort over a 10-year period that includes pre- and post-implementation observations of the California MPA network along the …

Analysis Of High Fat Diet Induced Genes During Mammary Gland Development: Identifying Role Players In Poor Prognosis Of Breast Cancer, Raquel C. Martinez-Chacin, Megan Keniry, Robert Dearth

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Background

Epidemiological studies have shown that consumption of a high-fat diet (HFD) increases the risk of developing breast cancer (BC). Studies in rodents have shown HFD causes changes in the genetic programming of the maturing mammary gland (MG) increasing the susceptibility of developing the disease. Less is known about how HFD induced genes impact BC development. HFD exposure two weeks before conception to six weeks of age was previously shown to dramatically change MG gene expression in 10 week old mice. Therefore, we investigated these differentially expressed HFD-induced genes for their expression in BC using the NKI 295 breast tumor …

Effect Of Patellar Component Thickness On Patellar Kinematics And Patellofemoral Joint Function Following Total Knee Replacement, Xin Xie

All Dissertations

Nowadays, instances of anterior knee pain and patellar fracture are more and more widely considered as significant complications following total knee replacement (TKR). The inability to freely flex/extend the knee after surgery has a critical influence on patients’ daily activities, which is one of the most common mechanical indications for TKR revisions. An overtly thick or thin patellar component selected intraoperatively in TKR surgery may cause postoperative complications, including excessive quadriceps tendon force, patellofemoral joint reaction force, and joint pain in TKR patients during knee joint motion.

The objective of the current study was to evaluate the effect of varying …

Parp-2 And Parp-3 Are Selectively Activated By 5' Phosphorylated Dna Breaks Through An Allosteric Regulatory Mechanism Shared With Parp-1., Marie-France Langelier, Amanda A Riccio, John M Pascal

Department of Biochemistry and Molecular Biology Faculty Papers

PARP-1, PARP-2 and PARP-3 are DNA-dependent PARPs that localize to DNA damage, synthesize poly(ADP-ribose) (PAR) covalently attached to target proteins including themselves, and thereby recruit repair factors to DNA breaks to increase repair efficiency. PARP-1, PARP-2 and PARP-3 have in common two C-terminal domains-Trp-Gly-Arg (WGR) and catalytic (CAT). In contrast, the N-terminal region (NTR) of PARP-1 is over 500 residues and includes four regulatory domains, whereas PARP-2 and PARP-3 have smaller NTRs (70 and 40 residues, respectively) of unknown structural composition and function. Here, we show that PARP-2 and PARP-3 are preferentially activated by DNA breaks harboring a 5' phosphate …

Effects Of Water Parameters On Container Mosquito (Diptera: Culicidae) Oviposition And Performance, Stephanie Sue Schelble

Master's Theses

Water body parameters have a considerable effect on the communities that develop within them. In small container habitats like tires, the depth, surface area, and volume effect the development and success of the mosquito communities. This study investigated the choices of the adult female mosquitoes, Aedes albopictus and Culex quinquefasciatus, between different depths and surface areas. In addition, larval performance was determined under differing depth and larvae densities. Oviposition studies showed that Ae. albopictus had a preference for deeper habitats (χ²= 14.2902, p= 0.0139) but did not prefer any surface areas (χ²= 7.2321, p= 0.0649) though …

Cloning And Expression For The Future Characterization Of The Air2 Protein, Emily Sue Frampton

Undergraduate Honors Capstone Projects

Air2 is a eukaryotic protein involved in multiple biological processes including protein-protein interactions as well as RNA binding. Air2 plays a critical role in RNA quality control and also helps regulate post-translational modification of various proteins. Although previous studies have revealed information regarding Air2's roles within a cell, the molecular and structural basis for Air2 function is unclear. Using a codon-optimized version of the Air2 gene, various constructs were created that improved the expression and solubility of Air2. Additionally a co-expression complex of Air2 with a PRMTI mutant, K13S, was made to obtain the Air2 protein with a native binding …

Upper Extremity Biomechanics Of Children With Spinal Cord Injury During Wheelchair Mobility, Alyssa J. Schnorenberg, Brooke A. Slavens, Adam Graf, Joseph J. Krzak, Lawrence C. Vogel, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

While much work is being done evaluating the upper extremity joint dynamics of adult manual wheelchair propulsion, limited work has examined the pediatric population of manual wheelchair users. Our group used a custom pediatric biomechanical model to characterize the upper extremity joint dynamics of 12 children and adolescents with spinal cord injury (SCI) during wheelchair propulsion. Results show that loading appears to agree with that of adult manual wheelchair users, with the highest loading primarily seen at the glenohumeral joint. This is concerning due to the increased time of wheelchair use in the pediatric population and the impact of this …
