Increasing Algal Productivity And Treatment Potential In Raceways Fed Clarified Municipal Wastewater, Christopher D. Pittner

Master's Theses

Two sets of triplicate pilot algal raceway ponds (1000-L, 0.30-m deep, paddle wheel mixed) were operated for 14 months at a California wastewater treatment plant to treat wastewater and generate algal-bacterial biomass as biofuel feedstock. Two experiments were run to determine the effect on biomass productivity of (1) hydraulic residence time (HRT: 2, 3, 4, or 4.5 days) and (2) feeding schedule (18 small pulses during 8 AM-4 PM [diurnal] versus 20 large pulses during 4 AM-12 AM [diel]). The target productivity was at least 20 g volatile suspended solids per m2 of pond per day. Additional output variables were …

Comparative Transcriptomic Analysis Of Developmental Stages In Isolated Mammary Epithelial Cells, Nicole K. Einfalt

Master's Theses

The mammary gland is an organ common to all mammals; it is of value for neonatal nourishment, human nutrition through dairy consumption, and is a source of pathology in humans through the development of breast cancer. While transcriptomic analyses have been applied to cultured mammary epithelial cells (MEC) and to whole gland samples, few have studied purified MEC isolated directly from the gland in vivo. To identify the differentially expressed genes influencing MEC development during pregnancy and the differences between the nulliparous and primiparous quiescent states, primary MEC were isolated from virgin, pregnant, and primiparous quiescent sibling mice. Computational …

A Novel All Wheel Drive Torque Vectoring Control System Applied To Four Wheel Independent Drive Electric Motor Vehicles Utilizing Super Twisting And Linear Quadratic Regulator Methods, Kenneth Daniel Schmutz

Master's Theses

This thesis contains the design and simulation test results for the implementation of a new all-wheel drive (AWD) torque vectoring (TV) control system. A separate algorithm using standard control methods is included in this study for a comparison. The proposed controller was designed to be applied to an AWD independent drive electric vehicle, however the main concepts can be re-purposed for other vehicle drive train configurations. The purpose of the control system is to assist the driver in achieving a desired vehicle trajectory whilst also maintaining stability and control of the vehicle. This is accomplished by measuring various real time …

Bi-Stability In The Wakes Of Platooning Ahmed Bodies, Daniel M. Stalters

Master's Theses

Autonomous heavy vehicles will enable the promise of decreased energy consumption through the ability to platoon in closer formation than is currently safe or legal. It is therefore increasingly important to understand the complex and dynamic wake interactions between vehicles operating in close proximity for aerodynamic gains. In recent years, a growing body of research has documented a bi-stable, shifting wake generated behind the Ahmed reference bluff body. At the same time, studies of platooning Ahmed bodies have focused on changes to the body forces and moments at different following distances or lateral offsets, typically based around time-averaged measurements or …

Master's Theses

Twenty-two young men and women of the 49^thMilitary Police Brigade of the California National Guard were participants of our nutrition education and health assessment program. The California National Guard has expressed concern of unsatisfactory physical and nutritional status of their personnel related to a nutrition knowledge deficit as evidenced by preliminary data of insufficient dietary intake and poor nutrition knowledge assessment scores. Our program was designed to implement a nutrition intervention including education and evaluate its effectiveness in reducing Metabolic Syndrome (MetS) risk factors, improving body composition, and providing educational lessons intended to alter lifestyle. Baseline data was …

Influence Of Natural And Anthropogenic Environmental Variability On Larval Fish Diet, Growth, And Condition In The Northcentral Gulf Of Mexico, Angie Hoover

Master's Theses

The northern Gulf of Mexico experiences high levels of freshwater runoff annually from various sources including the Mississippi River and Mobile Bay, among other sources. Early life history stages of fishes are especially vulnerable to environmental variability created by freshwater discharge. The objectives of this study were to describe the available prey field, diet, growth and condition of larval fishes with respect to various effects of freshwater discharge in the northern Gulf. The first chapter compared these parameters in larval Gulf Menhaden (Brevoortia patronus) collected from three different water masses characterized by physical and biological parameters after the …

Increasing Teachers' Use Of Behavior Specific Praise Via A Smart Watch, Kristi White

Master's Theses

This study evaluated the effects of a teacher prompting procedure to increase teacher behavior specific praise using a Smart Watch. Participants included three Head Start general education teachers. An ABAB design across participants was used to examine the effects of Smart Watch-based prompts on teachers’ praise rate. The study consisted of four phases: a) baseline, b) teacher praise training and intervention, c) withdrawal from intervention, and d) intervention reinstated. Implementation of the intervention resulted in increases of average behavior specific praise rates and general praise rates for all three participants. Although, averages fail to reach criterion set by the researcher …

Pathways Of Psychopathic Traits To Aggression Through Affective Correlates, Olivia C. Preston

Master's Theses

This thesis project examines the roles of empathy facets and emotion dysregulation in the relationship between psychopathic personality traits and aggression within an undergraduate sample. The project addresses three gaps in research – how psychopathic personality traits relate to empathy facets from a recently developed measure of empathy (Affective and Cognitive Measure of Empathy [ACME]; Vachon & Lynam, 2016); how psychopathic traits indirectly affect aggression functions (i.e., reactive, proactive) through empathy facets; and how emotion regulation contributes to these relations, above and beyond empathy. The sample was comprised of 368 university students. Findings indicated that largely all psychopathic traits were …

Antioxidant Genes In Apis Mellifera, Their Implication In Pesticide Detoxification, Nicholas Rinderer

Master's Theses

The effect of pesticides on Apis mellifera mortality as well as their effect on the transcriptional regulation of antioxidant genes was the aim of this study. Unlike previous studies, the work here shows the combined effects of pesticides imidacloprid and coumaphos on worker bees at levels likely encountered by workers using both toxological and molecular analysis. Bee brood were collected from hives and incubated until hatching. The 1 day old bees were then segregated and subjected to varying concentrations of coumaphos and imidacloprid both independently and in concert. Workers from each treatment group were removed and stored in RNA-later until …

Using Personality Traits To Predict Pectoral Fin Contact Initiation Role In Bottlenose Dolphins (Tursiops Truncatus), Riley Paige Macgregor

Master's Theses

Contact with the pectoral fin facilitates formation and maintenance of social relationships between dolphins (Dudzinski & Ribic, 2017). Additionally, several studies have shown that bottlenose dolphins have distinct personalities that are consistent across time and situation (e.g., Highfill & Kuczaj, 2007; Kuczaj, Highfill, & Byerly, 2012), and it has been suggested that these individual differences (i.e., personality) may influence tactile behavior exchanges. The current study therefore aimed to determine if bottlenose dolphin personality traits predict whether and how dolphins initiate contact as a rubber or rubbee during pectoral fin contact exchanges, and to identify whether the effects of personality traits …

Epic Adolescence: Contemporary Adolescence In Philip Pullman’S His Dark Materials, Chloe Felterman

Master's Theses

To find the truth of a societal construct or phenomena, it can help to look at the world of fiction and fantasy. Though this idea may seem ironic or counter-intuitive, one will find that fictional literature can reveal the working order of its respective society. Philip Pullman’s epic fantasy trilogy, His Dark Materials, uses and manipulates the traditional constructs of the genre to reflect and re-imagine the concepts of adolescence of the late-20^th and early-21^st centuries. Eleven-year-old protagonist Lyra Belacqua and subsequently her cohort, Will Perry, reveal the complications and difficulties modern American and British adolescents experience as …

The Song Style Of Antonio Carlos Jobim: An Analysis Of Four Songs, Rachel Rogers

Master's Theses

The songs of Antônio Carlos Jobim are a national treasure of Brazil, beloved around the world. Their beauty and subtle simplicity have enthralled audiences for the last 60 years, yet they often reveal some unusual construction. Following the lead of other Brazilian theorists, this study was commenced with the belief that applying rigorous theoretical analysis to bossa nova would show its qualityand enduring worth. Four songs were selected for analysis based on their importance in Jobim’s career and their centrality to the bossa nova genre, “Chega de Saudade,” “Corcovado,” “Insensatez,” and “Garota de Ipanema.” They are among the most recorded …

Late Quaternary Evolution And Stratigraphic Framework Influence On Coastal Systems Along The North-Central Gulf Of Mexico, Usa, Robert Hollis

Master's Theses

Coastal systems in the Gulf of Mexico are threatened to reduced sediment supply, storm impacts and relative sea level rise (RSLR). The geologic record can provide insights of geomorphic threshold crossings (formation, progradation, transgression, destruction) to these forcing mechanisms to predict future barrier evolution to climate change. The stratigraphic framework and antecedent topography directly influence coastal evolution over geologic timescales. This study synthesizes ~2100km of geophysical data, 700+ sediment cores, and 63 radiocarbon dates to regionally map two sequence boundaries, multiple ravinement surfaces and fourteen depositional facies. One marine isotope stage (MIS) 6 valley’s fill provided up to 300 x10 …

Investigating Possible Scurvy In The Postclassic Maya Of Tipu, Emmalea Gomberg

Master's Theses

Although residing in a tropical environment, numerous researchers have posited the possibility of scurvy in the Maya in recent years. The historic population of Tipu in western Belize dating to AD 1541-1638 is one of the largest and best preserved Maya series, and was therefore evaluated for possible presence of scurvy since the diet appears typical of the pre-contact Petén populations. The temporal bones and greater wings of the sphenoid were analyzed for scorbutic activity in 143 individuals, along with periodontal disease and antemortem tooth loss to determine if there was a co-occurrence with scurvy.

Overall, 27% of the sample …

Pseudomonas/Brachypodium As A Model System For Studying Rhizosphere Plant Microbe Interactions Under Water Stress, Janiece Mcwilliams

Master's Theses

In contrast to well-studied mechanisms of drought tolerance in plants, the interactions between plants and their microbiome during water stress are still poorly understood. This missing knowledge is crucial for the exploitation of beneficial microbial communities to improve the sustainability of agriculture under changing climatic conditions. The research described here bridged this gap by focusing on the molecular interactions between beneficial rhizobacterium Pseudomonas synxantha 2-79 and annual grass Brachypodium distachyon Bd21. 2-79 exemplifies a group of rhizobacteria associated with dryland wheat, while B. distachyon originates from the Middle East and has emerged as a model for valuable biomass, food, forage, …

Holocene Formation And Evolution Of Horn Island, Mississippi, Usa, Nina Gal

Master's Theses

Horn Island, one of the most stable barriers along the Mississippi-Alabama chain, provides critical habitat, helps regulate estuarine conditions in the Mississippi Sound, and reduces wave energy and storm surge for the mainland. This study integrates 2,200 km of high-resolution geophysics, 35 sediment cores, and 15 radiocarbon ages to better understand the formation and evolution of the island in response to sea-level rise, storms, and antecedent geology. The Biloxi and Pascagoula incised valleys converge at Horn Island and have played a profound role in the evolution of the system. Within the incised valleys, numerous shallow paleochannels between 4 and 9 …

Rhetoric, Legislation, And The Felony Offender, Cyrus Taylor

Master's Theses

Rhetoric is arguably of more importance than the message that is being overtly conveyed. Therefore, it is of great importance to understand how rhetoric can be utilized to convey one message while simultaneously transmitting another distinct message (Walter 2017). In this study, discourse analysis was conducted by examining the rhetoric associated with the Violent Crime Control and Law Enforcement Act (VCCLE), through the use of legislative speeches and newspaper articles, to determine how language has effectively resulted in the relegation of felony offenders within a class-based society. Utilizing two theories, class structure theory and distributive justice theory, an understanding was …

Posttraumatic Stress And Hazardous Alcohol Use In College Students: The Moderating Role Of Alcohol Protective Behavioral Strategies, Hallie R. Jordan

Master's Theses

The present study evaluated the moderating role of alcohol protective behavioral strategy subtypes (Al-PBS; Serious Harm Reduction [SHR], Manner of Drinking [MOD], Stopping/Limiting Drinking [SLD]) and gender on the relationships between traumatic stress symptoms and both hazardous drinking and alcohol-related negative consequences. Participants were 915 traditional age (18 to 25 years old) college students from nine universities in the United States who reported drinking in the past. All participants reported their gender and completed measures of traumatic stress symptoms, Al-PBS use, hazardous drinking, and alcohol-related negative consequences through an online survey. Experiencing greater traumatic stress symptoms was associated with both …

Parental Attachment And Adult Attachment: The Moderating Role Of Dispositional Forgiveness And Gratitude, Christian Ammons

Master's Theses

Secure parental attachment, characterized by trust, care, and autonomy granting, is associated with improved psychological functioning and adjustment to college and is often associated with adult attachment relationships. Similarly, adult attachment, a characteristic of adult relationships, has been associated with improved college adjustment. Individual differences such as dispositional forgiveness and gratitude are often associated with secure adult attachment but have not been examined in relation to parent child attachment. The current study examined dispositional forgiveness and gratitude as moderators of the relationship between parental attachment and adult attachment. A sample of 185 college students participated and as expected, parental attachment …

Vulnerable Narcissism, Self-Criticism, And Self-Injurious Behavior: Emotion Regulation As A Moderator, Philip Stoner

Master's Theses

College students of traditional age have an elevated risk of self-injury (McManus et al., 2015). Self-injurious behavior (SIB) often indicates increased mental health concerns and elevated suicide risk (Whitlock, Eckenrode & Silverman, 2006). Self-criticism represents a non-physical form of self-injury (Baetens, et al., 2015), which is also associated with psychological distress and suicidal behavior. Thus, it is important to understand the risk factors associated with SIB and self-criticism. Vulnerable narcissism has been linked to self-injury (Dawood et al., 2017); however, there is little consensus about the nature of this relationship. Moreover, vulnerable narcissism has been associated with impaired emotion regulation …

The Effect Of Changing Appraisals Of Current Life Success On Memories Of Love Towards Parents, Mario Herrera

Master's Theses

As we experience successes and failures in life, do we bias our memories of childhood? Cognitive appraisal theory would predict that emotions are elicited based on the current appraisal of an event or person. There is some research that these current appraisals can also distort memories of emotions surrounding an event. No past research has investigated whether current appraisal of life success would affect important autobiographical memories. Here, we examine the effects on childhood memory of love felt towards parents. Due to current appraisal theory, we expected memory of love towards parents would be prone to distortion and bias. We …

Ecological Stoichiometry: What Role Does It Play In The Competition And Spatial Distribution Patterns Of Aedes Albopictus And Aedes Aegypti?, James Deerman

Master's Theses

Ecological stoichiometry is the balance of chemical substances within animal bodies through interactions and processes within their ecosystem. Though relatively underexplored, it provides a wealth of information linking interactions across different levels of organization. Detritus is the base of the food web within the small aquatic ecosystems occupied by the mosquitoes Aedes albopictus and Aedes aegypti. Nutrient content of detritus varies, but it can have a negative effect on mosquito growth and survival if nutrient thresholds are not met. I investigated nutrient environments and species abundance in cemetery vases in New Orleans, LA to assess detrital heterogeneity and its …

The Influence Of Socioeconomic Status And Subjective Social Status On The Career Development Of College Students, Dylan Richard

Master's Theses

Social class is often examined across social science disciplines and contains two distinct parts: socioeconomic status (SES) and subjective social status (SSS). Researchers have established that college students from various SES backgrounds experience college differently, however little research has examined how universities and those that work with college students can help aid the career development of students given their SES. Career development is a broad area of research; therefore, the current study examines a number of career development variables that are key in understanding college students’ career development, such as career adaptability, career decision-making difficulty, work values, and vocational interests. …

Psychopathic Personality Traits As A Moderator Of The Relationship Between Social Intelligence And Relational Aggression, Savannah Merold

Master's Theses

Social intelligence has been identified as one of many predictors of relational aggression. It is likely that a certain level of social intelligence may be necessary for relationally aggressive behaviors to be effective (e.g., some ability to understand human behavior is necessary to effectively harm others through the manipulation of status, social relationships, or sense of belonging). And yet, social intelligence is unlikely to be sufficient to produce relationally aggressive behavior. Merely because someone has the requisite levels of social intelligence to use relational aggression does not mean that he or she will be motivated to do so. There is …

Political Beliefs, Region Of Residence, And Openness To Firearm Means Safety Measures To Prevent Suicide, Sarah E. Butterworth

Master's Theses

Firearms account for approximately half of all suicides in the US and are highly lethal, widely available, and popular; thus, firearms are an ideal candidate for targeted means safety interventions. However, despite their value as a suicide prevention tool, firearm means safety strategies are not widely utilized, possibly due to factors which impede openness to their use. This study examined the relationship between region, political beliefs, and openness to firearm means safety in a sample of 300 American firearm owners. Overall, firearm owners were more willing to engage in means safety for others than for themselves and to store firearms …

The Return Of The Dead: Resurrecting Chappell's Family Gathering, Jonathan Moore

Master's Theses

This thesis examines Fred Chappell’s virtually overlooked collection of poetry Family Gathering (2000), and how the poems operate within the mode of the grotesque. I argue that the poems illuminate both the southern grotesque and Roland Barthes’s theory of photography’s Operator, Spectator, and Spectrum. I address Family Gathering as a family photo album full of still shots, snapshots, and even selfies, which illumines how Chappell’s use of the grotesque in this collection derives more from its original association with visual arts rather than only depicting the grotesque typically associated with characteristics deemed explicitly shocking or terrifying. I argue that …

A Computational Analysis Of The Gradient Concentration Profile Of Deet And The Mosquito Behavioral Response, Brandon Carver

Master's Theses

DEET is a common active ingredient in most spatial repellents. DEET is also a volatile organic compound. DEET prevents mosquitoes from detecting and coming into contact with an human individual. Gas sensing technologies such as metal oxide semiconductor sensors can detect VOCs. The World Health Organization provides the majority of efficacy testing methods. This research adapts methods from the WHO and use of MOS sensors to further understand how and why DEET affects mosquitos. A custom developed system is used to measure DEET dissipation and observe mosquito behavioral response to the DEET. DEET dissipations and mosquito behavior is measured within …

Freshwater Invertebrate Assimilation Nutrients From Detrital Biofilms Under Light And Phosphorus Manipulation, Taylor Price

Master's Theses

Anthropogenic influences are increasing algal biomass and activity within aquatic ecosystems, stimulating debate regarding interactions between “green” and “brown” food webs. Specifically, in forested streams, the removal of forest canopy or riparian zones increases light exposure and nutrient fluxes to streams affecting primary productivity and carbon (C) flows across aquatic food webs. Further understanding the synergistic effects of light and nutrients on detrital biofilms may explain how aquatic detritivores respond to anthropogenic change. The objective of this study was to employ C and phosphorus (P) isotopic radiolabels to understand how microbial biofilm constituents (i.e heterotroph and autotroph) contribute C and …
