Student Peer-Group Focusing In Psychology Training: A Phenomemological Study, Amanda Burleigh Lowe

Electronic Theses and Dissertations

The present study is an empirical phenomenological investigation of the influence of peer group Focusing practice (Gendlin, 1981) on doctoral psychology students' senses of their developing clinical expertise. Focusing, a therapeutic bodily awareness and symbolization practice, was proposed as a method that would support the development of student self-reflection, self-assessment, and self-care. The present study investigates the experiences of three female doctoral students who participated in a peer-initiated and peer-run Focusing group for five semesters. The methodological procedures for a reflective empirical phenomenological study as articulated by Giorgi and Giorgi (2003), Robbins (2006), and Wertz (1984) were followed. Procedures adapted …

The Effect Of Risk Assessment On Racial Disproportionality In The Child Welfare System, Joseph Martin

Electronic Theses and Dissertations

Minority children are involved in the child welfare system at rates disproportionate to their numbers in the overall population. Prior research argues that risk assessments conducted by child welfare agencies may be racially biased, and thus contribute to disproportionality. This study seeks to explore the effect of different risk assessment models on racial disproportionality. This is done by examining the relationship between race/ethnicity and various child welfare outcomes in three states that utilize the consensus-based model and three states that utilize the actuarial model of risk assessment. Results were similar for both groups of states, suggesting that one model is …

A New Approach For Segmentation Of Breast Mr Images And Object-Retrieval Based On Correlation Between Different Types Of Breast Images, Donghoon Kang

Electronic Theses and Dissertations

Magnetic Resonance Imaging (MRI) has been used as the significant mean of diagnosing breast cancers. However, due to its high cost, several alternatives have been proposed recently. The motivation of the new approach in this paper is how to replace MRI with the alternatives which do not have enough diagnosis samples so that the reliability is not sufficient. In order to raise the reliability of the alternatives, we need to find correlations between MR images and the alternatives so that the enormous samples of MRI could be used to diagnose breast cancers with the more affordable methods. This paper introduces …

Only Nixon Could Go To China: L. Q. C. Lamar And The Politics Of Reconciliation, Richard Brian Wilson

Electronic Theses and Dissertations

Lucius Quintus Cinncinatus Lamar was a statesman with an almost unmatched career, serving on the President's Cabinet, in Congress, and on the Supreme Court. Lamar's work in government spanned one of the most tumultuous times in American history, and his transformation from secessionist to advocate for reconciliation in the post-Civil War period illustrates the complexity of politics at that time. This thesis examines Lamar's life and provides an historiographic survey of Lamar scholarship to date. From this review, the thesis moves to new and necessary areas of inquiry, including Lamar's relationship with black Reconstruction politicians, his role in the early …

Y'All Eat: Foodways, Performative Regional Identity, And The South In The Twenty-First Century, Kirsten Schofield

Electronic Theses and Dissertations

"Y'all Eat: Foodways, Performative Regional Identity, and the South in the Twenty-first Century" examines the ways in which iconic Southerners--Jim Beam and his ilk, Colonel Harland Sanders, and Paula Deen--create and sustain the hypercontemporary South. Because of their media exposure and place in the popular imagination, these characters force a specific kind of performance in both an intergroup and intragroup context. Close readings of individual appearances and selected portions of these characters' output help to shed light on how these identities are formed, upon what they rely for structure and support, and what this means for modern consumers around the …

Mixing It Up: Multiple Symbiont Acquisition Strategies As An Adaptive Mechanism In The Coral Stylophora Pistillata, Kristen A. Byler

Electronic Theses and Dissertations

In obligate symbioses, the host's survival relies on the successful acquisition and maintenance of symbionts, which can be transferred from parent to offspring via direct inheritance (vertical transmission) or acquired anew each generation from the environment (horizontal transmission). Vertical transmission ensures progeny acquire their obligate symbionts, but progeny encountering an environment that differs from that of their parent may be disadvantaged by hosting a suboptimal symbiont. Conversely, horizontal symbiont acquisition provides hosts the benefit of acquiring symbionts well suited to the prevailing environment, but progeny may fail to acquire their obligate symbionts. Here I show that the coral Stylophora pistillata …

Computer modeling in ANSYS AUTODYN was undertaken to calculate a numerical ballistic limit for each plate configuration. The …

Adaptive Tolerance To Ocean Acidification In The Marine Sponge: Chondrilla Nucula, Sylvester Lee

Electronic Theses and Dissertations

The dramatic increase in atmospheric carbon dioxide since the Industrial Revolution has led to a 30% increase in ocean acidification over pre-industrial levels. Although most ocean acidification research thus far has focused on calcifying organisms such as corals, the potential of this increase in acidity (H+ ions) to cause acid-base imbalances in soft-bodied animals such as sponges has been grossly overlooked. Furthermore, many studies on ocean acidification have not considered the elevated temperatures that are predicted to accompany future climate change conditions. Sponges are crucial components to coral reef systems, providing food, nutrients, structure, and support. The sponge Chondrilla nucula …

Temporal And Spatial Assessment Of Pahs In Water, Sediment, And Oysters As A Result Of The Deepwater Horizon Oil Spill, Meghan Christina Dailey

Electronic Theses and Dissertations

On April 20, 2010, BP's Deepwater Horizon oil rig exploded leaking over 200 million gallons of crude oil into the Gulf of Mexico for 84 days. Exposure to oil-associated polycyclic aromatic hydrocarbons (PAHs) in the water and sediment could severely impact the aquatic organisms inhabiting the Gulf of Mexico (i.e. developmental defects, reproductive effects, death, etc.). Therefore, water, sediment and oyster, Crassostrea virginica, samples were collected approximately bimonthly between May 26 and November 30, 2010 from multiple sites along the Gulf Coast, namely, two sites in Mobile Bay (Denton and Sand Reefs at 1 or 0.1 m above the bay …

Discovery, Isolation, And Identification Of Antimalarials From Fungal Endophytes, Andrekeus Lee

Electronic Theses and Dissertations

We examined fungal endophytes for their ability to inhibit bacterial, fungal and protozoal pathogens. Once antimalarial activity was discovered and confirmed, we sought to isolate and identify the active constituent(s) of our extracts. Bioassay-guided fractionation techniques were used to isolate our active compound, the structure of which was elucidated using 1H- and 13C-NMR. 2D-NMR and LC-MS analyses helped confirm that our endophytes were indeed producing artemisinin. Growth versus production studies were conducted to optimize our growth and extraction conditions while several other variables, like temperature and culture medium, were evaluated in an effort to improve our yields. Artemisinin production under …

Design Synthesis And Biological Evaluation Of Non-Peptide Neuropeptide Ff Ligands, Jessica Valentinas Mankus

Electronic Theses and Dissertations

Neuropeptide FF is an endogenous RF-amide with two receptor subtypes originally described as having anti-opioid characteristics. While peptide work helped to elucidate key features for targeting the subtypes of the neuropeptide FF receptor, non-peptide small molecules offer a more refined tool to discover features that affect selectivity and affinity. Improvements in small molecule ligands for neuropeptide FF support lead development and offer a clearer understanding of the binding pocket of each receptor subtype. Previous work on the lead 4–anilindopiperidine structure clarified a key feature between agonist and antagonist behavior. Early modifications of substituents of the piperidine nitrogen were tolerated and …

Impacts Of Race/Ethnicity And Self-Esteem On Body Dissatisfaction In Women, Kristie Vail Schultz

Electronic Theses and Dissertations

In the United States, there is a push for individuals to be of a particular size, and for women, that ideal size is extremely thin (Katzmarzyk & Davis, 2001). Overall, females indicate a greater drive for thinness and put more emphasis on weight and shape salience than do men (Anderson & Bulik, 2001), and they prefer a less muscular body type than men as well (Oehlhof, Musher-Eizenman, Neufeld, & Hauser, 2009). Among women, Caucasian females report more body dissatisfaction than do African American women (e.g., Kelly et al., 2011). Body dissatisfaction can be influenced by many factors; in addition to …

How Do The Perceived Barriers, Attitudes, And Knowledge Of Grocery Store Personnel Affect Availability Of Organic Food Products?, Rachel Adams

Electronic Theses and Dissertations

Organic food is one of the fastest-growing segments of food production and consumption in the U.S. Even though organic foods are becoming more widely available, some studies suggest they may not be equally available to all populations because people in some areas are being excluded from the organics market either geographically or financially. The purpose of this study was to examine how individual and local characteristics affect the attitudes of grocery store personnel toward organic food products and how these attitudes affect availability. Grocery store personnel were surveyed about their attitudes toward organic foods, their perceptions of the barriers to …

Nonviolent Bodies And The Experience Of Breakdown In The American Movement For Civil Rights, Danielle Andersen

Electronic Theses and Dissertations

This thesis examines the experience of personal breakdown in the American Civil Rights Movement.

An Examination Of The Effects Of The Sexual Double Standard On College Students' Condom Use, Cahryn Anderson

Electronic Theses and Dissertations

Men and women have historically been held to different standards regarding sexual behavior, known as the sexual double standard. Women have typically been judged more harshly than men for engaging in similar sexual behavior. Both genders report higher levels of sexual activity and more liberal attitudes since the 1940s. Males historically report engaging in more sexual activity than females. However, current studies indicate both genders are engaging in similar levels of sexual activity, although men continue to report slightly higher levels. It is unclear whether attitudes and judgments related to gender and sexuality have kept pace with reported behavior changes. …

Gender And Sexuality In Blame Attributions For Intimate Partner Violence, Jennifer April Balliet

Electronic Theses and Dissertations

In this project I explore how gender and sexuality impact how respondents blame perpetrators and victims of intimate partner violence (IPV). Victims of same sex intimate partner violence (SSIPV) have different experiences with IPV than do heterosexual victims, both in articulating their experiences and in seeking legal recourse or professional aid. Blame is at the core of the biases that result in differential treatment, and I discuss belief in a just world (BJW) and groupness perceptions in blame attributions, blame in relation to gender, sexuality, and IPV. I elaborate on the results of blame in practical terms. I used an …

The Potential For Screening For Interpersonal Violence In Community Pharmacies: An Exploratory Study, Marie Barnard

Electronic Theses and Dissertations

Intimate partner violence (IPV) is a public health problem of epidemic proportion; the only known effective health care intervention is routine screening for IPV exposure. Despite professional guidelines for routine screening, this intervention has been poorly adopted. Expansion of screening efforts to the community pharmacy setting provides an opportunity to have a substantial impact on the health, well-being of pharmacy patients. This investigation is the first to examine IPV screening related to the pharmacy environment. An existing measure of physicians' readiness to manage IPV (PREMIS) was adapted for the community pharmacy environment and validated in a national random sample of …

Identifying Dysfunction In Persistent Social Deviance: Perspective Taking As A Mediator Of The Relationship Between Psychopathy And Social Aggression, Olga Vadymovna Berkout

Electronic Theses and Dissertations

Psychopathy has been associated with social aggression in a number of studies. Perspective taking (e.g. theory of mind and empathy) has been inversely associated with both psychopathy and social aggression, suggesting that it may serve as a potential mediator of this relationship. Structural equation modeling (SEM) was used to assess perspective taking as a potential partial mediator of the relationship between psychopathy and social aggression in a sample of 439 undergraduates. Although bivariate correlations produced the expected negative relationships between perspective taking and psychopathy and social aggression, perspective taking did not function as a mediator in the SEM analysis. Implications …

Comparison Of Exercise And Eating In Collegiate Athletes Vs. Non-Athletes Active In High School Sports, Laura Leighton Blair

Functional Studies Of Novel Bioactives From Complex Host-Microbiomes As Drug Leads For Cancer, Infectious Disease, Depression And Pain, John Jason Bowling

Electronic Theses and Dissertations

The drug discovery process has become increasingly complex in comparison to early efforts particularly those involving diseases or conditions that affect large numbers of the human population. It is difficult to point directly to one factor leading evolution of the process but the definition of a mechanism of pharmacological action for a drug lead has noticeably become a higher priority. This evolution has helped diminish the stigma of natural products and compound supply issues. The issue of compound supply has also been addressed to some extent with the emergence of recombinant technologies and new synthetic methodology. With approximately 60 years …

Soil Phosphorus Availability And Buffering Capacity In Eastern South Dakota Assessed Using Quantity-Intensity Relationships And Diffusive Gradients In Thin Films, Rose Eitemiller

Electronic Theses and Dissertations

Phosphorus (P) availability is influenced by soil properties and depth, creating challenges for nutrient management across agricultural landscapes. This study evaluated two complementary approaches for quantifying P availability and adsorption dynamics in eastern South Dakota soils: Diffusive Gradients in Thin Films (DGT) and P quantity–intensity (Q–I) relationships. The objectives were to (1) quantify bioavailable P using DGT, (2) compare DGT measurements with established soil test P (STP), (3) evaluate Q–I parameters describing P adsorption characteristics, and (4) assess spatial variability in P availability across eastern South Dakota soils. DGT-measured P increased with STP levels and was strongly correlated with Bray-1, …

Feature-Based Neuro-Symbolic Networks For Global Diagnostics, Tracy Lynn Schantz

Electronic Theses and Dissertations

Engineered system diagnostics have been researched over the years with many successful results. From transportation systems to office technologies, many have been equipped with self-diagnostic capabilities and are called Smart Machines. In spite of these advances, current diagnostic systems are driven by direct sensory information without much concern for patterns of the system behavior or features associated with them. For large-scale systems with complex dynamics, global as well as local diagnostics become of great importance, where sensory information is used as input for the local diagnostics, and patterns of behavior or features are utilized for global diagnostics.

The main objective …
