Investigating How Students Communicate Tree-Thinking, Carrie Jo Boyce

Dissertations

Learning is often an active endeavor that requires students work at building conceptual understandings of complex topics. Personal experiences, ideas, and communication all play large roles in developing knowledge of and understanding complex topics. Sometimes these experiences can promote formation of scientifically inaccurate or incomplete ideas. Representations are tools used to help individuals understand complex topics. In biology, one way that educators help people understand evolutionary histories of organisms is by using representations called phylogenetic trees. In order to understand phylogenetics trees, individuals need to understand the conventions associated with phylogenies.

Barriers To Computer Programming Student Success: A Quantitative Study Of Community College Students In Southwest Missouri, Tiffany D. Ford

Dissertations

Student success in computer programming courses has been a long-studied problem and computer science major retention has historically been substantially lower than other majors. The issue of retention for computer science majors has become more pronounced in two-year, open-enrollment institutions. This quantitative study, grounded in Gardner’s theory of multiple intelligences, attempted to address some of the causes of poor retention for entry-level computer science majors at two-year colleges by looking for predictors of student success in their first computer programming course. Two of the intelligences from Gardner’s (1993) theory, Logical-Mathematical and Visual-Spatial, were used along with two factors: student success …

A Comparative Study Of The Population Dynamics Of Four Amaranthaceae Species, Lauren Michele Schwartz

Dissertations

Some of the most problematic agricultural weeds found in the Midwest United States are found in the Amaranthaceae family, such as Amaranthus palmeri and A. tuberculatus. These summer annual weeds are troublesome due to their competitive ability, high seed production, and resistance to herbicides from several modes of action which complicates management in field crops and has led to significant yield loss. Achyranthes japonica and Iresine rhizomatosa are two perennial species in the same family as A. palmeri and A. tuberculatus that occur in similar habitats as one another, but differ in invasiveness. Achyranthes japonica is a non-native, invasive species …

Computerized Behavioral Skills Training, Selection-Based Instruction, Lag Reinforcement Schedules, And The Emergence Of Topography-Based Responses To Interview Questions, John O'Neill

Dissertations

This investigation evaluated a computerized behavioral skills training package for teaching responses to interview skills by adolescents and young adults with learning disabilities. The package consisted of instructional videos, video-modeling, rehearsal, feedback, and selection-based instruction. Experiment 1 replicated and extended recent research which has suggested that a selection-based protocol operating on a lag schedule of reinforcement is an effective and efficient method for teaching responses to interview questions (O’Neill, Blowers, Henson, & Rehfeldt, 2015; O’Neill & Rehfeldt, 2014). The purpose was to address some of the limitations of these studies while testing the limits of the selection-based protocol in promoting …

The Relationship Between Toxic Leadership, Organizational Citizenship, And Turnover Behaviors Among San Diego Nonprofit Paid Staff, Melanie J. Hitchcock

Dissertations

Toxic leadership is associated with a number of negative consequences to the long-term health and welfare of people in organizations. Destructive leader styles redirect employee efforts from mission accomplishment to self-protection and survival behaviors, undermining the organization. Increased demand and decreased funding are characteristic of the nonprofit sector. Therefore, successful nonprofit organizations tend to rely on creativity and innovation to ensure their communities are appropriately and sufficiently sustained. Supportive, not toxic, leadership helps foster organizational environments that encourage prudent risk-taking and innovation.

This concurrent mixed methods study explored the relationship between toxic leadership and organizational citizenship and turnover behaviors among …

Motor vehicle crashes are a leading cause of death in the United States, cost Americans $277 billion annually, and generate serious psychological burdens. As a result, extensive vehicle safety research focusing on the explanatory factors of crash severity is undertaken using a wide array of methodological techniques including traditional statistical models and contemporary data mining approaches. This study advances the methodological frontier of crash severity research by completing an empirical investigation that compares the performance of popular, longstanding techniques of multinomial logit and ordinal probit models with more recent methods of decision tree and artificial neural network models. To further …

The Schoolyard As An Outdoor Classroom: Learning Through Experience, Jason W. Spray

Dissertations

When teaching ecology concepts, teachers often overlook utilizing the schoolyard as an outdoor classroom. This study examined the use of the schoolyard to teach ecology concepts in order to improve environmental knowledge and attitudes among fifth grade African-American students. The “Nature Unleashed” curriculum was the primary source for the lessons. This curriculum encompasses experiential learning and place-based education. The curriculum, taught over a six-week period, utilized hands-on activities inside and outside of the classroom. There were 248 fifth grade African-American students (N = 248) who participated in the research study. Students responded to a pre- and post-assessment to measure knowledge …

The Effects Of Schedule Density Of Reinforcement For Alternative Behavior On Resurgence, Kathryn M. Kestner

Dissertations

Resurgence is the reemergence of a previously extinguished response when an alternative response no longer produces reinforcement. Although returning to previously successful methods for obtaining reinforcement is likely advantageous, resurgence also occurs in the form of treatment relapse. An individual may return to problematic behavior (e.g., aggression, self-injury, drug use) when an alternative behavior (e.g., communication response, coping skill, social behavior, etc.) is no longer successful at producing a reinforcer. Behavior analysts rely on treatments based on differential reinforcement of alternative behavior, and resurgence has been demonstrated following changes to reinforcement schedules due to errors in treatment integrity or intentional …

Dissertations

The efficacy of Functional Analytic Psychotherapy (FAP) has not yet been show in randomized controlled trials in any population. The current study utilized a stratified randomization technique conducted by a computer system to assign twenty-three college students recruited for difficulties in interpersonal functioning who scored one standard deviation below the norm on the Fear of Intimacy Scale and met diagnostic criteria via independent assessment for Major Depressive Disorder, Generalized Anxiety Disorder, Social Anxiety Disorder, Avoidant Personality Disorder, or Dependent Personality Disorder to either a FAP condition or a Watchful Waiting Condition to assess the conditions ability to increase social relating …

Citizenship, Politics And Process: A Cross National Study Of Citizenship Regimes, Marisha Lina Lecea

Dissertations

Citizenship policy is important for democracies and for the people who live in them. Citizenship status is important for the individual enjoyment of social, political and human rights, and restricting access to citizenship can hamper a state’s enjoyment of legitimacy and stability. Across democracies, citizenship policies range from no allowance for dual nationality and very onerous naturalization policies, to acceptance of dual nationality and non-capricious paths to naturalization. The question of this dissertation is what accounts for the variation in citizenship regimes across democracies?

I argue that it is domestic politics through party in power, judicial review and strength of …

Using Stories As The Landscape Of Writing: A Case Study Of Mentor Texts In The Elementary Classroom, Christine Mcdowell

Dissertations

In this dissertation, I investigate the way in which mentor texts are defined and implemented by four elementary classroom teachers within one school district, and how this mode of instruction allows for an increase in teacher autonomy while still addressing Common Core State Standards. This project focuses on each participant as they share a common goal in writing instruction while maintaining their teaching identity and curricular freedom.

One goal of this study is to provide the educational theory that supports mentor text instruction that is missing from the movement. Many teaching guides exist that explain the concept of mentor texts, …

Exploring The “Mojo” Of Presidential Awards For Excellence In Mathematics And Science Teaching (Paemst) Recipients, James W. O'Malley

Dissertations

The purpose of this dissertation was to determine how extraordinary science teachers develop their teaching mojo. The teachers investigated were recipients of the prestigious Presidential Award for Excellence in Math and Science Teaching (PAEMST). This investigation focuses specifically on science instruction. The method used for this investigation was individual and group interviews conducted with eight PAEMST recipients. Five themes emerged from these interviews: 1. Science is a natural motivator for learning; 2. Students need to be scientifically literate citizens; 3. A critical “trigger event” propelled each of these teachers towards great science instruction; 4. Each sought out and engaged in …

Regulation Of Glial Cell Line-Derived Neurotrophic Factor (Gdnf) Production In Voluntary And Involuntary Muscle, John-Mary Vianney

Dissertations

Glia cell line-derived neurotrophic factor (GDNF) is a survival factor for subpopulations of neurons, including somatic and autonomic motor neurons. These neurons depend, in part, on GDNF that is synthesized and secreted by their target tissues. It has been shown that a number of tissues in the periphery express GDNF and these target tissues differ in their composition, function, and in the case of different muscle cell types, their contractile characteristics. Whether the processes regulating GDNF production in these different tissues is similar or different is poorly understood. The broad goal of this study is to examine factors that normally …

Identifying The Molecular Mechanisms Of Early Cachexia Using Whole Transcriptome Sequencing In Muscle And Fat Biopsies From Cancer Patients, Amal Hussain Al Hadad

Dissertations

Cancer cachexia is responsible for one third of cancer–related deaths and contributes to the death of many others. More than 80% of cancer patients are cachectic towards the end of life. Despite intensive research, the mechanisms of cancer cachexia are still poorly understood. It is our hypothesis that identification of early changes in gene expression in cachexia will lead to an improved understanding of the mechanism that trigger this important problem in cancer patients. Thus, to shed light on the mechanisms involved in the major cachexia target tissues, we investigated the entire transcriptome in muscle and fat to identify altered …

High Frequency Field Potentials Of The Cerebellar Cortex, Jonathan David Groth

Dissertations

The cerebellum plays a crucial role in motor coordination along with basal ganglia and the motor areas of the cerebral cortex. Both somatosensory and the cerebro-cerebral pathways bring in massive amounts of neural information to the cerebellum. The output of the cerebellar cortex projects to various motor cortices as well as down to the spinal cord to make its contributions to the motor function.

The origin and function of the field potential oscillations in the cerebellum, especially in the high frequencies, have not been explored sufficiently. The primary objective of this study was to investigate the spatio-temporal characteristics of high …

Accounting For Midblock Pedestrian Activity In The Hcm 2010 Urban Street Segment Analysis, Albert Forde

Dissertations

The Urban Street segment analysis Chapter of the 2010 Highway Capacity Manual (HCM 2010) provides a methodology for analyzing automobile performance on signalized roadway segments within an urban roadway network. The methodology involves applying a platoon dispersion model to: a) predict the vehicle arrival flow profiles at a downstream signalized intersection; b) use the predicted arrivals to compute the proportion of vehicle arrivals on green; and c) subsequently estimate the delay, travel speed and Level of Service (LOS) under which the segment operates. Vehicles arriving during the red interval at a signalized intersection generally accumulate and form a platoon. When …

Piezoelectric Scaffolds For Osteochondral Defect Repair, Sita Mahalakshmi Damaraju

Dissertations

Osteoarthritis is one of the most prevalent causes of disability affecting nearly 27 million Americans. Osteoarthritis is caused when extensive damage occurs to the articular cartilage later spreading to the underlying subchondral bone, resulting in osteochondral defects. The current clinical therapies aim at regenerating the hyaline cartilage, but instead fibrocartilage forms at the osteochondral defect site, which is inferior in structure and function and fails to integrate with the surrounding tissue. A biomimetic scaffold, which can provide cues similar to the native extracellular matrix, may facilitate osteochondral defect repair. Articular cartilage and bone extracellular matrix have been shown to produce …

Climate-Driven Change In Himalayan Rhododendron Phenology, Robert Evan Hart

Dissertations

Phenology – the seasonal timing of life-history events – is a critical dimension of natural history. It is also one of the earliest and most noticeable traits by which organisms respond to climate change. However, these responses are complex, and only beginning to be understood, especially in the montane and alpine environments that are among the ecosystems most vulnerable to climate change. Drawing from diverse data sets and employing multiple methodologies, I examined how climate affects phenology in Himalayan Rhododendron spp. Comprehensively monitoring flowering phenology over gradients of season and elevation on Mt. Yulong, China – home to a diverse …

Functional Analysis Of Gambling, Mack S. Costello

Dissertations

Given high rates of gambling and the growing population of disordered gamblers, there is a need to develop assessment strategies with improved treatment validity. More specifically, assessment strategies are needed that identify the controlling variables for disordered gambling and, thus, provide guidance in the selection of treatment and prevention strategies. This study sought to develop a functional analysis for gambling by utilizing a simulated gambling environment in which contextual variables hypothesized to be causally linked to disordered gambling could be systematically manipulated. Seven experienced gamblers participated in the multi-element, single-subject experimental study. Participants who endorsed at least some problems from …

Dissertations

Family members of ICU patients may experience anxiety, depression, and acute stress disorder symptoms. A need identified by the multi-society task for critical care research was to study the usefulness of interventions to quantify and treat anxiety, depression, and stress symptoms experienced by family members of ICU patients (Deutschman et al., 2012). This task force encouraged investigating using technology to address this need. (Deutschman et al.). The purpose of this prospective, quasi-experimental nonequivalent control group (pretest/posttest) design study was to compare the effect of standard ICU education and a web-based education program about the ICU environment on the level of …

Maturity Of Cloud Application Interoperability Frameworks For Small To Medium Enterprises, John Warde

Dissertations

Cloud computing has many benefits and organisations have bought into the cost effective and elastic solutions provided by major players in the market. However, cloud computing and Cloud Service Providers (CSP) are still evolving, hence there are differences in how customers connect with each provider to the orchestrate application lifecycle management. A lack of standards can create vendor lock-in. This work investigates current research and possible solutions to the vendor lock-in problem through the use of Cloud Interoperability or multi-cloud frameworks. Software developers and organisations can use these frameworks which abstract the differences between CSPs and mitigate vendor lock-in. A …

Using a mixed-method design of quantitative and qualitative approaches, this study investigated the utility of implementing an adapted version of Mindfulness-Based Relapse Prevention for Addictive Behaviors (MBRP; Bowen, Chawla, & Marlatt, 2011) with six men on probation or parole. The researcher integrated a focus on anger management into the eight MBRP sessions and taught mindfulness meditation exercises during a weekly group. Outcome variables of mindfulness, anger, and empathy were measured at baseline and immediately after the intervention. Field violation and parole revocation data were provided by the Missouri Department of Corrections 30 days following completion of the program. The participants’ …

In Search Of Spirit: The Making And Meaning Of Gay Spirituality, David Willilam Hart

Dissertations

Over the past two decades, a substantial number of scholarly studies have examined the confluence of religious and sexual minority identities (Kocet et al., 2011; Love, Bock, Jannarone, & Richardson, 2005; Rodriguez & Ouellete, 2000; Schuck & Liddle, 2001). Religious identity was often framed within a traditional Judeo-Christian context. A major limitation of this body of work is the neglect of spiritual identity as a construct separate from religious identity. Many Protestant, Judaic, Islamic, and Catholic doctrines regard homosexuality and gender non-conformity as deviant and view the expression of same-sex attraction as errant and immoral (Haldeman, 2002). While reconciliation of …
