Race And Sexual Orientation Lssues In Graduate Classrooms: How Faculty In Psychology Experience Them Emerging Alongside One Another, Raymond L. Sheets Jr.

Dissertations

The inclusion of sexual orientation and race-related issues into mainstream psychology has gained much needed momentum in recent years. The field of counseling psychology, in particular, has helped fuel this momentum with its appreciation for, and commitment to, developing academic and applied psychologists who attend to an evolving multicultural society. Within the academic environment, faculty members have the responsibility of facilitating student learning in their respective classrooms; this facilitation becomes challenging in the face of emotionally charged topics such as race and sexual orientation. How then do graduate faculty who teach these courses experience race and sexual orientation comingling within …

Bio-Socially Inspired Strategies In Support Of Dynamic Spectrum Access: An Evolutionary Game Theory Perspective, Mohammad Ali Marzoug Abu Shattal

Dissertations

Dynamic Spectrum Access (DSA) has been introduced to fulfill the expanded need for spectrum by different wireless networks and applications. Within the realm of spectrum access, the problem of "spectrum crunch" is present since some of the spectrum bands are overcrowded and others are underutilized. DSA aims to alleviate the problem of spectrum crunch. In DSA, Primary Users (PUs) allow Secondary Users (SUs) to access the spectrum as long as they do not interfere with PU transmissions beyond a pre-agreed acceptable level. In this work, a bio-socially inspired approach is proposed for SU interactions in support of better throughput for …

High School Seniors' Educational Experience Lnfluencing The Decision To Pursue A Career In Nursing, Ryan L. Rowe

Dissertations

Many high school students interested in nursing as an occupation choose to engage in a Career and Technical Education (CTE) program and subsequently progress through the exploration stage of Super’s Career Development Theory in a succinct, deliberate, and intentional manner. While CTE continues to serve as an educational option for many high school students interested in nursing, its value as a means for students to crystallize, specify, and implement the choice to pursue the high-wage, high-skill, and high-demand career of nursing is not understood to the extent possible. CTE is regularly overlooked as a viable educational option by high school …

A Hybrid Parallel Approach To High-Performance Compression Of Big Genomic Files And In Compresso Data Processing, Sandino N. Vargas Pérez

Dissertations

Due to the rapid development of high-throughput low cost Next-Generation Sequencing, genomic file transmission and storage is now one of the many Big Data challenges in computer science. Highly specialized compression techniques have been devised to tackle this issue, but sequential data compression has become increasingly inefficient and existing parallel algorithms suffer from poor scalability. Even the best available solutions can take hours to compress gigabytes of data, making the use of these techniques for large-scale genomics prohibitively expensive in terms of time and space complexity.

This dissertation responds to the aforementioned problem by presenting a novel hybrid parallel approach …

An Examination Of Behavior Analysts' Treatment Selection Behavior For Escape-Maintained Problem Behavior, Rebecca Eldridge

Dissertations

The advent of functional analysis procedures has helped identify reinforcers for problem behavior; however, the behavior analyst is then faced with the task of selecting an appropriate treatment for problem behavior. When selecting treatments, in addition to behavioral function, behavior analysts also need to consider contextual variables, such as current client repertoires, setting conditions, time and resources of current caregivers, as well as client and caregiver goals (Benazzi, Horner, & Good, 2006). Board Certified Behavior Analysts (BCBAs) must consider these factors when developing treatment according to their ethical code (Behavior Analyst Certification Board [BACB]’s Professional and Ethical Compliance Code [PECC], …

A Qualitative Investigation Of The Interpersonal Changes White Psychology Trainees Experience During Their Race-Based Learning And Development, Molly K. Beagle

Dissertations

The current study expands upon prior research that has explored how white psychology and counseling graduate trainees are impacted by their learning about racism. Prior to this study being conducted, research primarily addressed the psychological impact of learning about racism for white trainees. There was minimal acknowledgment and exploration of how learning about racism impacted the interpersonal aspects of trainees’ lives, such as their relationships and larger social networks. The current study addresses this gap within previous research, with it being the first to have an intentional, exclusive focus on the interpersonal impact of learning about racism. The primary purpose …

A Phenomenology Of Calling Among Undergraduates At A Public University: Reliance On Faith During An Intentional Career Decision-Making Process, Justin Arnold

Dissertations

Recent studies in vocational psychology and student development have discussed the fact that many college students value spirituality, and that a spiritual calling is positively associated with desirable work traits (Astin, Astin, & Lindholm, 2011; Chickering, 2006; Dik & Duffy, 2012; Duffy & Dik, 2013; Hunter, Dik, & Banning, 2010). What has yet to be deeply explored is how undergraduates at a public university who believe they are called explore careers and make vocational decisions.

The purpose of this phenomenology was to describe and interpret the lived experiences of emerging adults at a public university who believe they are called …

Structures Of Derived Graphs, Khawlah Hamad Alhulwah

Dissertations

One of the most familiar derived graphs are line graphs. The line graph L(G) of a graph G is the graph whose vertices are the edges of G where two vertices of L(G) are adjacent if and only if the corresponding edges of G are adjacent. One of the best- known results on the structure of line graphs deals with forbidden subgraphs by Beineke. A characterization of graphs whose line graph is Hamiltonian is due to Harary and Nash-Williams. Iterated line graphs of almost all connected graphs were shown to be Hamiltonian by Chartrand. The girth of a graph G …

The Effectiveness Of Using Leadership Practice Lnventory (Lpl 360) Feedback On Leaders' Lnsight Into Their Leadership Behaviors In Higher Education, Abdulrahman S. Alajlan

Dissertations

One of the most popular 360-feedback processes for leadership development is the Leadership Practice Inventory (LPI 360). According to the Leadership Challenge website the LPI tool has been translated into six languages. In addition, it has been implemented in a variety of organizations around the world and there are about 500 studies that have been built around it. However, the popularity of the LPI 360-feedback is not enough reason for it to be adopted for higher education without assurance that it aligns with a higher education organization’s specific vision and goals. After reviewing approximately 153 LPI studies across 766 databases …

Statistical And Clinical Equivalence Of Measurements, Puntipa Wanitjirattikal

Dissertations

This study proposes a test for statistical equivalence of two measurements. Typically, a new measurement process Υ is compared to an existing or standard measurement process Χ. We are assuming that Χ and Υ are measurements on the same scale. The paired t-test may be used to check for significant difference between (Χ, Υ) pairs. However, the paired t-test is intended to detect shift-type relationships of the form Υ=Χ+δ1 and may have low power for scale-type relations of the form Υ=γΧ.

We propose a test that has reasonable power to …

Distributed Model Predictive Control Of Power Converters In Microsrids Under Different Modes Of Operation, Riyadh Toman Thahab Toman

Dissertations

Microgrids consist of many distributed energy sources (DERs) and the overall system is viewed as a number of subsystems. In this work, a finite control set model predictive control is proposed to control power converters in both grid and island modes of operation of the microgrid. Each subsystem is assigned a local controller that relies on measurements of common coupling point (PCC) and/or terminal quantities to provide accurate regulation of current or voltage components. This meets the local objective of each subsystem and contributes to the global objective of the microgrid.

In the first part of the work, a microgrid …

How Friendships Between Heterosexual And Sexual Minority Counseling Psychology Doctoral Students Affect Anti-Heterosexist Identity Development, Amber L. Sylvan

Dissertations

As the field of counseling psychology strives to embrace diversity and social justice issues, sexual minority issues have flourished into an active area of study among scholars and an area of focus for LGBT-affirming practitioners. One area of emphasis has been on how heterosexual people develop Anti-Heterosexist Identities. Some studies have noted the importance of friendship as it relates to Anti-Heterosexist Identity Development (Asta & Vacha- Haase, 2012; Duhigg, Rostosky, & Gray, 2010; DiStefano et al., 2000; Gelberg & Chojnacki, 1995; Larson, 2012), however, no known studies have more deeply explored the role of crosssexuality friendships. The purpose of this …

Self-Generated Absorption Filter Based Optical Densitometry Calculations For Expanded Gamut And Spot Color Printing On Paperboard For Packaging Applications And Proposed Oba Index, Awadhoot Vijaykant Shendye

Dissertations

In the printing industry, process color printing is a very common way of reproduction of color photographic images. As continuous tone reproduction is not possible, images are converted to halftone format. Process control of a halftone image quality is carried out by measuring optical density of solid patches. ISO 5 defines measurement of optical density, formula, filters and requirements. As per ISO document optical density can be calculated only for the 4 colors cyan, magenta, yellow and black, known as process colors. To enhance quality of color reproduction of images, the number of reproducible colors are increased by gamut expansion. …

Peri-Operative Regional Nerve Blocks (Pnb) In The Treatment Of Pain In Patients Undergoing Operative Fixation Of Lower Extremity Fractures, Joshua K. Radi

Dissertations

This research explores current approaches to managing pain control in patients undergoing operative fixation of lower extremity fractures. As opioid use in the U.S. and abroad increases, alternative methods of treating and preventing opioid requirements are being examined. Patients with lower extremity fractures are susceptible to nonunion when anti-inflammatories are consumed, so alternative approaches are warranted. One such alternative, a peri-operative regional nerve block (PNB), is accomplished by injecting local anesthetic adjacent to one or more peripheral nerves supplying the area of the fracture to decrease pain (Fowler, Symons, Sabato, & Myles, 2008). The goal of this research was to …

An Lntegrated Approach (Remote Sensing, Hydrogeology, Geotechnical, And Geoinformatics) To Assess And Monitor Fossil Aquifers And Associated Land Deformation Over The Arabian Peninsula, Abdullah Ghurmullah Saeed Othman

Dissertations

Deformational features such as subsidence, sinkholes, fissures, settling and cracks in buildings and structures, and earthquakes are being reported from many of the world’s arid lands, in areas where fossil aquifers are being excessively exploited. Using the Lower Mega Aquifer System (LMAS) in Arabia as a test site, I applied an integrated approach (remote sensing, geodesy, GIS, geology, hydrogeology, and geotechnical) to identify nature, intensity, spatial distribution, and factors controlling the observed deformation in the central (Al-Qassim and Ha'il regions; area: 16×10⁴ km²) and the northern (Wadi As-Sirhan Basin; area: ~10.9×10⁴ km²) Arabia. A four -fold approach was adopted to …

Teaching Students Who Have Difficulty Mastering Lmitation, Jennifer Mrljak

Dissertations

Some children with autism are unable to acquire imitation despite receiving early intensive behavioral intervention (EIBI) meant to teach that and other important skills. Many EIBI programs use physical-prompting hierarchies either as a component of the discriminative stimulus or the correction procedure following an error (Lovaas, 1981; Maurice, Green, & Luce, 1996). But even after lengthy exposure to these teaching techniques, some children still do not acquire imitative repertoires. In the present study, working with students who were not acquiring imitative repertoires, we started with shaping the initial imitative responses as a method to gain stimulus control and then introduced …

Ldentifying And Characterizing Cognitive Factors Significant To Practicing And Learning Meteorology, Peggy M. Mcneal

Dissertations

To see the world as a meteorologist, one must understand and interpret atmospheric processes through representations depicted on two-dimensional weather charts and maps that encode large amounts of spatial and numerical data. This is a cognitively demanding and spatially challenging task, especially for students with burgeoning levels of meteorology knowledge, who lack the expertise of practiced meteorologists that read such charts and maps with ease. With little prior work informing meteorology and meteorology education through a cognitive science lens, this study surveys the literature and follows models of discipline-based education and cognitive science research to identify the discrete intelligence factors …

Controlling Political Corruption In Latin America: Institutional Constraints On Executive Power, George G. Lluberes

Dissertations

Corruption has remained resilient in Latin America. In just two decades, six Latin American executives from five distinct countries have faced impeachment processes resulting in removals from office due to issues surrounding corruption. Certainly, corruption has been a longstanding challenge to Latin American democracy and good governance. This study analyzes this phenomenon while discerning between grand and petty corruption. By focusing on executive corruption specifically, this study creates a more nuanced understanding of what affects corruption at high-levels of government in Latin America.

Why have political corruption levels in Latin America remained stagnant in spite of significant gains in political …

Evaluation Instruction In Council On Education For Public Health Accredited Master Of Public Health Schools And Programs, Kristin Ann Hobson

Dissertations

Despite the increasing role of evaluation in public health practice and research (Association of Schools and Programs of Public Health [ASPH], 2006; Institute of Medicine [IOM], 1998; Public Health Functions Steering Committee, 2008; United States Government Accountability Office [GAO], 2012), as well as Henry and Mark’s (2003) assertion of a need for systematic evidence on evaluation training and education, the literature continues to lack studies on evaluation instruction in Council on Education for Public Health (CEPH)-accredited Master of Public Health (MPH) schools and programs. As such, this study explored evaluation instruction in CEPH-accredited MPH schools and programs in the following …

Diagnostics For Choosing Between Stratified Logrank And Stratified Wilcoxon, Jhoanne Marsh C. Gatpatan

Dissertations

Martinez and Naranjo (2010) proposed a pretest for choosing between Logrank or Wilcoxon test in a two - sample case. However, in the presence of covariates, comparing two populations without adjusting for covariates would yield misleading results. In this study, we propose several pretests that will help the analyst decide to use stratified Logrank or stratified Wilcoxon tests in comparing two survival curves after covariates have been taken into account. Power performance of each adaptive test was done through simulations under PH and non-PH cases.

High Performance Computing Techniques For Analyzing Risky Decision Making, Vinay B. Gavirangaswamy

Dissertations

The process or activity of making choices when subject to gain or loss can be understood as risky decision making (RDM). Risky Decisions consists of outcomes of decisions that may probabilistically result in unfavorable results. Every organism that lives faces this challenge and recent research suggests that there is a computational process involved in making these decisions. This has led to new approaches in the study of RDM. My dissertation is towards contributing to expand on the existing knowledge of RDM processes.

The core contribution of my work is an analysis and development of high performance computing techniques that improves …

Optimal Combiners For Multiple Classifier Systems, Mohammed Falih Hassan

Dissertations

A Multiple Classifier System (MCS) is designed to combine classification results of an ensemble of different classifiers and consequently to produce the highest possible classification output. MCS has recently drawn growing attention and has become a necessity, especially when a problem involves a large class of noisy data or when using a single pattern classifier that has serious drawbacks in its results. A wide range of pattern recognition applications have benefited from the implementation of MCS, these include areas such as handwriting recognition, incremental learning, data fusion, feature selection, and a large variety of medical applications.

Color-Connected Graphs And Information-Transfer Paths, Stephen Devereaux

Dissertations

The Department of Homeland Security in the United States was created in 2003 in response to weaknesses discovered in the transfer of classied information after the September 11, 2001 terrorist attacks. While information related to national security needs to be protected, there must be procedures in place that permit access between appropriate parties. This two-fold issue can be addressed by assigning information-transfer paths between agencies which may have other agencies as intermediaries while requiring a large enough number of passwords and rewalls that is prohibitive to intruders, yet small enough to manage. Situations such as this can be represented by …

A Deep Learníng-Based Data Minimization Algorithm For Big Genomics Data In Support Of Lot And Secure Smart Health Services, Mohammed Aledhari

Dissertations

In the age of Big Genomics Data, institutes such as the National Human Genome Research Institute (NHGRI),1000-Genomes project, and the international cancer sequencing consortium are faced with the challenge of sharing large volumes of data between internationallydispersed sample collectors, data analyzers, and researchers, a process that up until now has been plagued by unreliable transfers and slow connection speeds. These occur due to the inherent throughput bottlenecks of traditional transfer technologies. One suggested solution is using the cloud as an infrastructure to solve the store and analysis challenges. However, the transfer and share of the genomics datasets between biological laboratories …

Lgbt Microaggressions In Counselor Education Programs, Sarah Bryan

Dissertations

Many lesbian, gay, bisexual, and transgender (LGBT) people report they experience microaggressions, small daily insults and indignities that affect their well-being. For LGBT students, microaggressions have been shown to affect well-being and academic engagement. In order to serve LGBT students and model affirming behaviors, counselor educators must be able to recognize and address LGBT microaggressions when they occur; however, there is currently a paucity of research on LGBT microaggressions in counselor education programs. Most studies on attitudes toward LGBT people in such programs neglect the experiences of LGBT students. Moreover, the few existing studies of the experiences of LGBT …

Investigation Of A Mindfulness-Based Intervention With Survivors Of Interpersonal Violence, Laura Elise Stayton
