Ostracism And Antisocial Behavior: The Role Of Perceived Justice, Entitlement, And Anger, Christopher Jeffrey Nathanael Lustgraaf

Master's Theses

Recent research has demonstrated that antisocial behavior following a general ostracism experience is mediated by increased feelings of entitlement (Poon, Chen, & DeWall, 2013) and anger (Chow, Tiedens, & Govan, 2008). However, this prior research has failed to determine whether ostracism in general leads to antisocial behavior, or only ostracism that is perceived of as unfair or unjust. The purpose of the current study was to manipulate the perceived fairness of the ostracism experience (fair or unfair) and assess participants’ antisocial behavioral intentions (i.e., dishonest intentions). It was hypothesized that an unfair ostracism experience (compared to a fair ostracism or …

The Effects Of Tootling On Disruptive And Academic Behaviors In High School, John Dylan Ken Lum

Master's Theses

Considered the opposite of tattling, tootling is a procedure where students report their classmates’ positive behavior instead of inappropriate behavior. This study examined the effects of tootling on students’ behavior in three general education high school classrooms. An A-B-A-B withdrawal with follow-up design was used to assess the effects of the intervention on decreasing classwide disruptive behavior and increasing academically engaged behavior. Students wrote tootles anonymously on paper slips, and deposited them into a marked container. An interdependent group contingency procedure was used to create a class goal for the number of submitted tootles, which led to a class reward …

An Ethnography Of Taste: Craft Beer Culture In Hattiesburg, Yingkun Hou

Master's Theses

This thesis studies the craft beer culture in Hattiesburg in order to answer the research question: Is taste what draws people to this culture? Beyond conducting classic participant-observation, I deployed the method of sensory activated participant-observation in my fieldwork. In so doing, this research centers the perspective and the data collected on the senses, especially the taste of craft beer. The purpose of this research is to add to our knowledge of the anthropology of the senses and contribute to the literature on the anthropology of taste.

Elucidating The Molecular Function Of Reprolysin Metalloproteases In Tick-Host-Pathogen Interaction, Jaclyn Bo Williams

Master's Theses

Ticks are ectoparasites that attach to their host for many days to weeks, feeding to engorgement and continuing their species life cycle. The mechanisms behind the successful feeding and manipulation of host immune responses have been associated with the secretion of their specialized saliva. Tick saliva includes a variety of modulatory molecules that must disrupt and counteract defense mechanisms, including a variety of proteases. Reprolysin Metalloproteases, in the Zn²⁺ dependent family, is secreted as a proenzyme and is shown to have proteolytic activity, degrading fibrinogen and gelatinase activity, as well as disturbing homeostasis¹². Previous work with …

Design Of A Non-Contact Home Monitoring System For Audio Detection Of Infant Apnea, Daniel T. White

Master's Theses

Infant apnea is a widespread condition in which infants fail to effectively breathe, and can lead to death. Clinical solutions exist for continuous monitoring of respirations in a hospital setting and requiring constant skin contact. This thesis investigates the construction of a proof of concept device that performs in-home monitoring without skin contact and with commonly available off-the-shelf components.

The device constructed used a directional microphone to detect breathing sounds, an omnidirectional microphone to detect ambient noise as a baseline to help isolate the breathing sounds, and LabVIEW software deployed on an inexpensive laptop computer to quantify incidents of apparent …

Zebrafish And Conditioned Place Preference: A Translational Model Of Drug Reward, Adam Douglas Collier

Master's Theses

Addiction and substance abuse commonly lead to negative outcomes such damaged health, domestic violence, child abuse, failure in school, and loss of employment. In the United States, hundreds of billions of dollars accrue annually in costs associated with healthcare, crime and lost productivity due to addiction. Efficacious treatments remain few in number, the development of which will be facilitated by comprehension of environmental, genetic, pharmacological and neurobiological mechanisms implicated in the pathogenesis of addiction. The zebrafish (Danio rerio) has recently gained popularity as a model organism of complex brain disorders (e.g., substance use disorder). Behavioral quantification within the conditioned place …

Tissue Characterization Using Optical Coherence Tomography, Mina Mahdian

Master's Theses

Optical coherence tomography (OCT) is a non-invasive imaging modality, which provides real-time near-histology resolution images. In dentistry, OCT has been used for early detection of carious lesions, malignant changes in the oral tissues and other indications. However, to the best of our knowledge there is no information regarding the ability of this imaging modality in differentiating between different types of tissues in the oral cavity. If OCT proves to be able to render information regarding the properties of tissues, it can be used to detect pathological changes at an early stage, which results in better treatment outcomes. In this study, …

Self-Compassion And Mindfulness Differentially Predict Eating Behaviors Among Emerging Adults, Tosca Braun

Master's Theses

Objectives: Poor eating behaviors (EB) and food cravings (FC) represent risk factors for obesity and related outcomes. Mindfulness and self-compassion (SC) have been individually linked to healthful EB in prior research, representing salient intervention targets. While conceptualized as having health behavioral self-regulatory benefits, no research has examined these variables’ differential contributions to EB and FC.

Method: Participants were 283 university undergraduates (152 females; m. age = 19.1 + 1.6; m. BMI = 23.7 + 4.2 kg/m²). Multiple regression analyses in women (W) and men (M) assessed how validated measures of mindfulness and SC were associated with Fruit/Vegetable intake …

Improvements To Optical Diagnostics Of Thermal Barrier Coatings: Contaminant Identification During Laser Cleaning And Time Gated Photoluminescence Piezospectroscopy, Hyung Nun Kim

Master's Theses

Laser ablation has previously been demonstrated as a technique for removal of contaminants from engine-run thermal barrier coatings (TBC). A method for monitoring the concentrations of some of the known constituents of the contaminants is developed for paralleled quantification during laser cleaning. The major constituents of these contaminants, CaO, MgO, Al₂O₃, and SiO₂, also termed CMAS, are prepared in pressed powder samples for which Laser-induced Breakdown Spectroscopy (LIBS) is applied. During LIBS, unique spectra characterizing the contents of the ablated material are obtained. LIBS is applied to the individual CMAS constituent pressed powder samples …

Efficiency And Safety Of A Continuous Rotation Instrumentation System And A Reciprocating Motion Instrumentation System: A Randomized Clinical Trial, Justin P. Farmer

Master's Theses

Introduction: It has been suggested that single-file reciprocating systems, such as WaveOne, are capable of more rapid root canal instrumentation compared to systems that utilize multi-file continuous rotation. The purpose of this study was to evaluate the efficiency and safety of WaveOne and ProTaper Next instrumentation systems in vivo in a randomized clinical trial. The null hypothesis was that no differences would be seen in canal preparation time, working length control, or occurrence of adverse events. Materials and Methods: A total of 89 teeth requiring primary non-surgical endodontic treatment were included in the study. Root canal therapy was performed per …

An Analysis Of Juvenile Chinook Salmon Outmigration Speed And Survival In Response To Habitat Features: Sacramento River From Knights Landing To Sacramento, California, Natalie N. Mcnair

Master's Theses

Outmigration is an important life stage for Chinook salmon (Oncorhynchus tshawytscha) survival in the Sacramento River, and yet our understanding of their behavior and needs during this time is limited. To gain a better understanding of their survival and movement rates during outmigration, late fall run Chinook salmon smolts were tracked using acoustic telemetry techniques. Habitat features were measured and quantified throughout the study area to evaluate how Chinook salmon respond to key levee features including shade, instream woody material, and aquatic vegetation. The overall average movement speed through the entire study area was 0.77 m/s with an …

Characterization Of Pressure-Driven And Electro-Kinetically Driven Flow In A Micro-Fluidic Chip Using Particle Imaging Velocimetry, Alexis Weckel

Master's Theses

The flow profiles of pressure-driven and electro-kinetic driven flows were compared for a microfluidic chip. It was found that the pressure-driven flow had a parabolic profile while the electro-kinetic flow had a plug shaped flow profile. The measured velocities were similar to those determined by the Poiseuille flow model and the Helmholtz-Smoltchowski equation. Flow uniformity is very important for control in microfluidic mixers. Parabolic flow profiles lead to inconsistent reactions while the more uniform plug shape flow allow for a more steady reaction across the channel. Previous work had been performed to measure the flow of a solution of fluorescent …

Analysis Of The United States Hop Market, Michael W. Dasso

Master's Theses

Hops are one of the four main ingredients used to produce beer. Many studies have been done to analyze the science behind growing and harvesting hops, creating hop hybrids, and how to brew beer with hops. However, there has been little research done revolving around the economic demand and supply model of the hop market. The objectives of this study are to create an econometric model of supply and demand of hops in the United States from 1981 to 2012, and to identify important exogenous variables that explain the supply and demand of hops using the two-stage least squares (2SLS) …

In India poor sanitation accounts for 1,600 daily deaths of children under the age of five (Dasra, 2012). The societal and environmental conditions in India and many other developing countries have continuously stood as barriers to facilitating changes in sanitation behavior. Efforts made to improve hygiene have continuously faced opposing forces including major gaps between the supply and demand of sanitation. This paper will focus on one pilot program conducted in Chennai, India over the summer of 2014. This program was designed to teach school children safe sanitation and hygienic habits by providing a guiding tool to teachers. The study …

The Smart Growth Implications Of The Los Angeles Adaptive Reuse Ordinance, Forrest F. Chamberlain

Master's Theses

The Los Angeles Adaptive Reuse Ordinance (ARO) is an incentive program that encourages building reuse through regulatory exemptions. The ARO was partially intended to reduce vehicle miles travelled by encouraging mixed commercial and residential uses in existing buildings within Downtown Los Angeles and areas poised for redevelopment (Mayor’s Office of Economic Development, 2004, pp. 22, 51). Researchers and planners claim that the ARO helped to reduce vehicle miles travelled (Bell, 2014; Los Angeles Department of City Planning, 2014d; Bullen & Love, 2009; Bernstein, 2012), but these claims are not supported by discussions of the spatial distribution of ARO projects in …

An Investigation To Detect Delamination In Composite Laminated Plates Under Dynamic Loading, Jason Christopher Starnes

Master's Theses

In recent years composites have progressively been used for large-scale structures such as aircraft, ships, ground vehicles, and wind turbine blades. Traditional Nondestructive Evaluation (NDE) techniques have various limitations in assessing the performance of the large-scale composite structures. For instance, many techniques have the ability to measure either global or local properties but cannot measure both simultaneously. Nondestructive vibration detection techniques present a potential solution for evaluating both local and global large-scale composite structures, which are largely based on the fact that damage in a structure influences its dynamic characteristics such as modal parameters and Frequency Response Functions (FRF).

High Moisture Extrusion Of Oatmeal, Brandon F. Coleman

Master's Theses

Oats are considered to be a highly nutritious breakfast food available to consumers. Heightened consumer interest in functional food products and advances in human nutrition have led to increased levels of interest in the development of new oat based products (Webster and Wood 2011). Developments in technology have led to manufacturing of instant oatmeal, making the product more convenient to consumers. Low moisture extrusion processing is one of the most widely used methods to produce ready to eat breakfast cereals; however, there has been little research carried out to determine if high moisture extrusion methods would be viable. This study …
