Can Dolphins Cooperate To Solve A Novel Task?, Kelley Ann Winship

Master's Theses

Bottlenose dolphins cooperate in a variety of contexts, including foraging,acquiring mates, playing, and assisting distressed conspecifics. To better understand the capacity for cooperative behaviors, animals are often given tasks that require pairs of animals to coordinate their actions in order to receive a reward. This paper reports the results of an aquatic version of one such task: cooperative rope-pulling. Three groups of captive bottlenose dolphins (Tursiops truncatus) were given an apparatus that could most easily be opened by the two animals working together. Two untrained adult males at one location were successful in opening the apparatus together, sharing …

Personality And Relational Aggression In College Students: The Role Of Social Anxiety And Rejection Sensitivity, Daniel Locke Deason

Master's Theses

Relational aggression involves the intentional infliction of harm via damaging one’s relationships or sense of belonging. Previous research suggests that relational aggression among children and early adolescents is correlated with social ostracism, poor psychological adjustment, anxiety, and depression in victims, and there is increasing evidence that many of these correlates apply to relational aggression among older adolescents and emerging adults. Efforts to identify predictors of relational aggression are underway; however, many variables which have been influential in understanding other forms of aggression have not yet been examined. The Five Factor Model (FFM) of personality is one example, as it has …

Material Coefficient Of Thermal Expansion Investigation For Use In Additive Manufacturing Fused Deposition Modeling For Composite Tooling, Daniel Joseph Miller

Master's Theses

Polymer matrix composites are being used to manufacture light weight, high stiffness aircraft structures. These structures are often manufactured from carbon fiber reinforced epoxy. When these structures are damaged, they must be repaired to restore strength to the component to avoid the cost and logistics of having replacements parts. Occasionally, these repairs require tooling in order to make a quality repair, however, tooling generally has a long lead time. Additive manufacturing could be used to manufacture rapid tooling to create tooling for composite repairs. The issue is that polymer printed tooling has a much higher coefficient of thermal expansion (CTE) …

Reducing Disruptive Behavior In High School: The Good Behavior Game, William Blake Ford

Master's Theses

Disruptive behavior in the classroom setting negatively impacts the learning process in various ways, interfering with the educational process of individual students, the teacher, and/or the class as a whole. Class-wide levels of disruptive behaviors worsen these impacts and are often related to problems with a teacher’s classroom management techniques and abilities. Group contingency interventions, such as the Good Behavior Game (GBG), are often used to provide teachers with evidence based management strategies while improving student behavior in the class. Furthermore, group contingency interventions, such as the GBG, can be conceptualized as Tier I or Tier II interventions within a …

Observations On The Life History Of The Bayou Killifish, Fundulus Pulvereus (Everman 1899) In Mississippi Tidal Marshes, Leah Corrine Gaines

Master's Theses

This study provides insight into the life history of the relatively unknown intertidal marsh fish Fundulus pulvereus (Everman), the bayou killifish. Monthly sampling for F. pulvereus took place in three different Mississippi tidal marshes over a period of 17 months (n=445). Observations on the diet, parasite fauna, and fecundity of the bayou killifish were documented on all specimens collected. Percent Occurrence and Percent Number coupled along with multivariate analyses indicated seasonal, site, and ontogenetic shifts in the diet of F. pulvereus. Dominant prey items consumed by F. pulvereus were copepods, mites, chironomids, and terrestrial and aquatic insects. The bayou …

Effects Of Pre-Release Physical Stressors On Post-Release Success Of Hatchery-Reared Spotted Seatrout, Taylor Westbrook Guest

Master's Theses

Alteration of habitat associated with coastal development and increased demand for food and recreation can result in the depletion of fisheries resources such as the Spotted Seatrout (Cynoscion nebulosus), the Gulf of Mexico’s most popular recreational fish. Stock enhancement, or the release of cultured fish to supplement wild populations, is one potential tool for managing important fisheries resources. Although much effort has gone into marine stock enhancement, the effectiveness of stocking is not well established, and techniques for ensuring success have not been developed. Although the basic biology of the Spotted Seatrout is well known, comparatively little is known about …

Stressed Induced Changes In Karenia Brevis Ribosomal Rna, David Scott Jayroe

Master's Theses

Karenia brevis is a toxic marine dinoflagellate that causes harmful algal blooms (HABs), also known as red tides, in the Gulf of Mexico. These blooms are responsible for massive fish kills, shellfish bed contaminations, adverse human health effects, and vast economic loss. For these reasons, extensive research has gone into understanding the mechanisms and dynamics of bloom behavior by studying K. brevis in the field and in the lab. In order to understand higher order bloom behavior and dynamics it is imperative to understand K. brevis at the cellular level. In growing K. brevis in vitro under a variety of …

Clarifying The Association Between The Subtypes Of Narcissism And Suicide Risk, Stephanie Michelle Pennings

Master's Theses

Further research is needed to clarify the relationship between narcissism and suicidality. Ambiguous results yielded by past studies may be attributed to the two distinct forms of narcissism (i.e., grandiose and vulnerable). The current study aimed to examine the association between the components of the interpersonal-psychological theory of suicidal behavior (IPTS; Joiner, 2005; i.e., thwarted belongingness, perceived burdensomeness, and the acquired capability for suicide) and the two subtypes of narcissism. The potential explanatory effect of emotion dysregulation, a construct linked to the development of suicide risk, on the relationship between the forms of narcissism and the components of suicide risk …

Meeting In The Middle: The Impact Of Single-Party Dominance On Partisan Politics, William Samuel Adcock

Master's Theses

Polarization within the American government has reached near historic levels in recent decades. One of the most readily apparent results of this partisan atmosphere is the increase in the number of American states that are almost totally controlled by one of the two major political parties. This study seeks to examine the effect this single-party domination has on the policy positions of Senate candidates of the minority parties in these states. It is hypothesized that minority party candidates seeking election in these states will be more likely to adopt policy positions more commonly associated with the platforms of the majority …

Exploring Sexual Differentiation In The Tammar Wallaby Using Transcriptomics, Jenny Y. Kwok

Master's Theses

Sex determination and sexual differentiation are some of the most well studied topics in human development. Sex determination is the point where the undifferentiated gonad becomes committed to the ovarian or testicular pathway. This event can be triggered genetically or environmentally. Sexual differentiation occurs after sexual determination and involves the maturation of the gonad, which in turn, coordinates the corresponding physical and behavioral phenotypes. Disorders of sexual development (DSD) are among the most common congenital abnormalities seen in humans and are increasing at an alarming rate. Congenital DSDs can be caused by genetic, hormonal, and/or environmental stimuli. Increased exposure to …

Gradient Effects Of Reading Ability On Talker-Specific Perceptual Learning, Shayna R. Marmon

Master's Theses

Abstract

The acoustic signal of speech is a complex signal that simultaneously cues the linguistic content of a talker’s message and the identity of the talker. Traditional models of speech perception proposed that the properties of the acoustic signal that cue linguistic meaning and talker identify were distinct. However, a growing body of evidence challenges this traditional view, indicating that linguistic and talker-specific phonetic information are tightly linked in language comprehension. One of these benefits is increased intelligibility of the spoken message when listening to a familiar talker compared to an unfamiliar talker. Just as experience with a talker’s voice …

Changes In Hospital Utilization Among Seriously Mentally Ill Patients Following Enrollment In An Integrated Primary And Behavioral Health Care Program, Christopher L. Steele

Master's Theses

Persons diagnosed with serious mental illness (SMI) suffer from significant health disparities with respect to mortality, morbidity and health care access. The SMI population frequently over-utilizes hospital services, especially emergency department care, and often lacks adequate primary care. This retrospective longitudinal study investigated whether SMI patients changed their hospital utilization patterns when enrolled in an integrated primary care and behavioral health program and how these changes affected hospital costs. The study tracked the hospital utilization of 343 patients for up to 12 months before and after their enrollment. Results showed a significant decrease in total ED visits and the number …

Exploring The Physiological Role Of Vibrio Fischeri Pepn, Sally L. Cello

Master's Theses

The primary contributor to Vibrio fischeri aminopeptidase activity is aminopeptidase N, PepN. Colonization assays revealed the pepN mutant strain to be deficient at forming dense aggregates and populating the host’s light organ compared to wildtype within the first 12 hours of colonization; however the mutant competed normally at 24 hours. To address the role of PepN in colonization initiation and establish additional phenotypes for the pepN mutant strain, stress response and other physiological assays were employed. Marked differences were found between pepN mutant and wildtype strain in response to salinity, acidity, and antibiotic tolerance. This study has provided a foundation …

The Development Of Apartheid In The Naqab Israel’S Prawer Plan And The Jewish National Fund’S Blueprint Negev, Ayla Jay Schoenwald

Master's Theses

This study seeks to critique and confront past and present iterations of political Zionism through a combination of historical excavation and discursive analysis, informed by the present embodiment of this discourse in the form of violence and violations of Palestinian human rights in the context of the Naqab, the southern region of historic Palestine, where Bedouin communities continue to reside and resist Israel's (ongoing) colonization of their land. The Prawer Plan, a proposed Israeli policy to be implemented in the Naqab/Negev, threatens approximately 70,000 Arab Bedouin Israeli citizens of with forced expulsion and displacement. In addition, 35 Bedouin villages unrecognized …

Evaluating Urban Design Strategies For Climate Change Adaptation In Los Angeles, Kerby Andrew Olsen

Master's Theses

Human interference with the Earth’s climate, through the release of greenhouse gasses (GHGs), is estimated to have already increased average statewide temperatures in California by 1.7° Fahrenheit (F), with a further 2.7°F of warming expected by mid-century. The negative impacts of increased temperatures may be especially acute in mid-latitude cities that currently enjoy a mild climate, such as Los Angeles (LA), which are projected to warm to a point that will significantly affect human health and well being. The built environment increases urban temperatures through building materials that readily absorb heat from the sun, a lack of vegetation, a lack …

Theory Of Mind Without A Language Model: Effects Of Social Experience, Education And Language Exposure, Deanna L. Gagne

Master's Theses

Theory of Mind (ToM) abilities, i.e., the understanding that others’ internal states differ from one’s own, and that these states guide behavior, are multiply determined. ToM abilities underlie later social and pragmatic abilities, grossly affecting later life experiences, particularly for deaf children. However, previous studies have not clearly identified the effects of language, hearing status, or other exogenous factors, such as education or executive function abilities, on ToM development. To disentangle these, we studied three understudied populations in Nicaragua: Homesigners, who have not acquired a conventional language but have developed gestural communication systems; users of Nicaraguan Sign Language, an emerging …

Development Of An Autonomous Single-Point Calibration For A Constant Voltage Hot-Wire Anemometer, Ryan Murphy

Master's Theses

Traditionally, the measurement of turbulence has been conducted using hot-wire anemometry. This thesis presents the implementation of a constant voltage hot-wire anemometer for use with the Boundary Layer Data System (BLDS). A hot-wire calibration apparatus has been developed that is capable of operation inside a vacuum chamber and flow speeds up to 50 m/s. Hot-wires operated with a constant-voltage anemometer (CVA) were calibrated at absolute static pressures down to 26 kPa. A thermal/electrical model for a hot-wire and the CVA circuit successfully predicted the measured CVA output voltage trend at reduced pressure environments; however, better results were obtained when the …

Vibration-Based Health Monitoring Of Rotating Systems With Gyroscopic Effect, Nenad Gavrilovic

Master's Theses

This thesis focuses on the simulation of the gyroscopic effect using the software MSC Adams. A simple shaft-disk system was created and parameter of the sys-tem were changed in order to study the influence of the gyroscopic effect. It was shown that an increasing bearing stiffness reduces the precession motion. Fur-thermore, it was shown that the gyroscopic effect vanishes if the disk of system is placed symmetrically on the shaft, which reduces the system to a Jeffcott-Ro-tor. The second objective of this study was to analyze different defects in a simple fixed axis gear set. In particular, a cracked shaft, …
