Guided by ecological systems and relational coordination theories, this mixed methods dissertation explored how communication and joint decision-making between these professionals - two key components of interprofessional collaboration (IPC) - affects the safe and timely reunification of foster children

The quantitative phase involved analysis of administrative data collected from one urban county in a mountain region state. Logistic regressions were run to test if caseworker communication and joint decision-making with …

Anti-Fat Bias And Attentional Capture, Larissa Catherine Miller

Electronic Theses and Dissertations

Explicitly-rated anti-fat attitudes are correlated with weight-based discrimination, which is rampant in society today as many countries grapple with soaring rates of obesity. Early perceptual processes, such as conscious awareness and visual attention, may be biased based on the weight of the perceived or the perceiver, or any number of individual perceiver characteristics regarding weight-biased attitudes and experiences. The three experiments presented used continuous-flash suppression (CFS) to mask body stimuli, thereby hoping to gain insight into attentional capture of unseen images and its relation to anti-fat attitudes. The pattern of findings in the three experiments presented suggest that what makes …

Synergistic Environmental Aging Of Glass Reinforced Polymer Composites, Tianyi Lu

Synergistic effects involved in the environmental degradation of Glass Reinforced Polymer (GRP) composites were examined and a novel synergistic aging model was proposed in this study. Six GRPs based on glass fibers with four different polymer resins and six pure polymer thermoplastic resins were exposed either individually or in combination to ultraviolet (UV) radiation, water condensation and elevated temperature for approximately 1000 h. The composites and polymers were monitored for weight changes as a function of time and their surfaces were examined after the tests using optical and scanning electron microscopes (SEM). Photodegradation of the polymer matrices was analyzed by …

Resonances Of Love And Social Complexity In The Circadian Novel: Virginia Woolf, Christopher Isherwood, And Mulk Raj Anand, Mikayla Marie Peters

Electronic Theses and Dissertations

Both Mulk Raj Anand and Christopher Isherwood admired and borrowed from Virginia Woolf's Mrs. Dalloway to build their own circadian novels. This thesis attempts to apply three major theories from three different disciplines - narrative theory, sociology, and psychology - to three major circadian novels to explain how societal pressures and the past influence the protagonists' connections with others. Woolf's Mrs. Dalloway (1925), Anand's Untouchable (1935), and Isherwood's A Single Man (1964) all use a circadian (single-day) structure to explore how the past influences every decision in a single day. This thesis combines Michel de Certeau's Theory of the Everyday …

Social Belonging And Built Space: Using Contact, Contention, And Common Conditions To Create Multicultural And Multifaith Shared-Space In A Repurposed Aurora, Colorado, Church, Kassandra Irene Soppas Neiss

Electronic Theses and Dissertations

Global patterns of human displacement and migration are diversifying the user base of urban churches. This change produces new settings of cross-cultural encounter and adaptation of social space. This study examines the transition of a Lutheran church into a multifaith and multicultural community center. In Aurora, Colorado, a majority-minority city, the facility offers vital support for immigrants, refugees, and low-income community members while maintaining links with [previous] congregants. Using ethnographic methods, I explore the cultural dimensions of repurposed space for a diverse constituency. Discussed herein are the ways in which the physical space is interpreted, how contention and divergent experiences …

Capturing Transmission And Distribution Connected Wind Energy Variability, Abdulaziz Alanazi

Electronic Theses and Dissertations

Although renewable energy provides a viable solution to address ongoing challenges of the economy and the environment in modern power systems, the variable generation of this technology results in major technical challenges for system operators. This issue is becoming more severe as the penetration of renewable generation is increasing. This dissertation addresses the variability challenge of renewable energy resources in transmission and distribution levels of modern power systems.

For transmission level, this dissertation focuses on wind generation fluctuation. Three methods of reducing wind generation fluctuation are investigated from an economic perspective, including (a) dumping the wind generation, (b) using battery …

Design And Analysis Of A Non-Isolated High Gain Step-Up Cuk Converter, Yasser Almalaq

Electronic Theses and Dissertations

Renewable energy sources, such as solar energy, are desired for both economic and ecological issues. These renewable energy sources are plentiful in nature and have a terrific capability for power generation. The only drawback of solar energy, which is one of the best forms of energy sources, is that the output has a low voltage and needs to be stepped up in order to be inserted into the DC grid or an inverter for AC applications. To overcome this drawback, a high gain DC-DC power converter is required in this kind of system. These power converters are needed for a …

Integration And Segmentation Conflict During Ensemble Coding Of Aspect Ratio, Elric Matthew Elias

Electronic Theses and Dissertations

The visual system often integrates information that "goes together". Once information has been integrated, summary information (e.g., average emotion or average size) can be extracted; this occurs during ensemble coding. Integration thus allows for fast and efficient generalizations about sets to be made. In contrast, the visual system sometimes segments input that does not go together. For example, the perception of objects can be exaggerated away from natural category boundaries (e.g., a perfect circle is a category boundary; it is neither "flat" nor "tall"). Segmentation allows the visual system to make quick categorical distinctions. Much of the time, integration …

Proximate And Ultimate Consequences Of Stressed-Induced Maternal, Paternal, And Joint Parental Effects In A Changing World, Whitley Rayen Lehto

Electronic Theses and Dissertations

Parental experience can alter the developmental and rearing environments of offspring, resulting in parental effects on offspring traits. I addressed the consequences of stress-induced maternal, paternal, and joint parental effects from both ultimate (ecological/evolutionary) and proximate (physiological/epigenetic) perspectives. I used a full-factorial design in which threespine stickleback (Gasterosteus aculeatus) mothers, fathers, both, or neither were exposed to a model predator at developmentally appropriate times to test for predator-induced maternal, paternal, and joint parental effects on daughters’ mating behavior and egg glucocorticoids (stress hormones) and on offspring gene expression. Maternal and paternal predator exposure independently yielded daughters who preferred …

The number of app downloads poses a challenge for mobile application testers to find the right approach to test apps. This dissertation extends the FSMWeb approach for testing web applications [50] to test mobile applications (FSMApp). During the process of analyzing FSMWeb how it could be extended to test Mobile Apps, a number of shortcomings were detected which we improved upon. We discuss these first. We …

Stigma In The Post Crisis Age: External Barriers To Accessing Hiv Treatment, Internalized Trauma, And Strategies Of Support In Orlando, Florida, Julian Cerrell Nilsson

Electronic Theses and Dissertations

In 2017, The CDC (center for disease control and prevention) released a memo confirming popular medical opinion that an HIV positive person with an undetectable viral load was unable to transmit the HIV virus. While treatment and prevention options are advancing, this advancement may not translate directly into reduced stigma, which is produced and reproduced by external barriers to accessing healthcare, and internalized by HIV positive people as emotional trauma. This research explores the relationship between the availability of contemporary resources for the treatment and prevention of HIV/AIDS, and the environment of stigma experienced by positive gay and bisexual men …

Protection Of High-Voltage Transformer Bushings And Other Brittle Structures Against Impact, Christine Nichole Henderson

Electronic Theses and Dissertations

This dissertation contributes unique approaches to improve the fundamental understanding of the impact behavior of porcelain high-voltage (HV) transformer bushings under high-velocity impact, with a focus on their protection with feasible methods which could be quickly applied in service to prevent vandalism and other undesirable impact situations. The bushings are brittle and pressurized; prone to explosive damage when hit by a high-velocity projectile. Damaged bushings can destroy transformers and entire substations in complex fashions. This can put the power grid at risk for cascading failures and electrical blackouts, affecting consumers. Therefore, suggesting practical approaches which could be used to protect …

Interrogating Racialized Scripts: Parents And Students Organized For Leading Educational Justice, Stefanie Iona Gurulé

Electronic Theses and Dissertations

This qualitative critical case study portraiture examines several racialized scripts found in family engagement, educational leadership, and social justice literature regarding under-resourced parents and students of color as leaders for educational justice. These scripts, or dominant narratives, discuss racially-minoritized parents and students as deficient in character and culture. They also deem that educational leadership for social justice is too complex an issue for these parents and students to have any positive effect. Therefore they are viewed in the literature as being only passively active in their own education. Analyzing a successful and authentic parent and student activist organization that focused …

Teachers And Creativity In The Classroom, Krystal Dawn Flanders

Electronic Theses and Dissertations

Fostering creativity within the classroom can have numerous positive and lasting effects that support students in becoming adults who are inquisitive, curious, critical thinkers, as well as risk takers (Amabile & Kramer, 2012; Beghetto, 2015; Craft, 2003; Csikszentmihalyi, 2013; Hennessy, 2017; Piirto, 2004; Starko, 2018). Sternberg (2007) argues that, since the world is changing at a faster pace than ever before, students will need to continuously deal with new and unusual tasks and situations. Although the research identifies the importance of creativity in the classroom, the research also finds a trend in teachers' limited understanding of what creativity is and …

Increasing Distribution Grid Hosting Capacity Through Wire And Non-Wire Solutions, Abdulrahman N. Almazroui

Electronic Theses and Dissertations

Increased deployment of distributed generation (DG) can adversely impact the operational performance of distribution networks. This increment can potentially change network power flow and result in several operational issues such as reduced power quality, overvoltage, and ineffective protection. In order to quantify the degradation bounds of distribution operation due to increasing DG integration, the concept of hosting capacity is introduced. The aim of this thesis is to increase the DG hosting capacity in distribution network by proposing several wire and non-wire solutions. To this end, these solutions include network reconfiguration, reactive power control, and energy storage system deployment. The network …

The Cultural Transmission Of Gender Roles In Childhood, Sarah Ariel Lamer

Electronic Theses and Dissertations

In the present work, I summarize extant theories and evidence on how children learn about gender roles and test an ecological framework for gender-role learning (i.e., the Gendered Ecology Model). Existing theory has demonstrated that children begin to form symbolic representations of gender as young as 9 months and acquire basic gender stereotypes about behaviors and activities considered appropriate for each gender by 3 years. Theories have proposed several potential sources and moderators of how children learn about the roles that women and men generally hold. However, no theories have examined these sources from an ecological approach, leaving open the …

Psychotherapy Task-Based Assessment Of Therapists' Multicultural Orientation: A Measurement Development Study, Shaakira Haywood Stewart

Electronic Theses and Dissertations

Multicultural competencies (MCCs) have laid the foundation for therapists and researchers to strongly consider culture as an important factor in psychotherapy. More recently, Owen (2013) developed the multicultural orientation framework (MCO) to better explicate the MCCs for psychotherapy. The purpose of this dissertation was to develop a Multicultural Orientation Performance Task (MCO-PT) and coding system with therapists-in-training. For the MCO performance task, participants responded to eight brief simulated therapy situations that centered on the intersection of various cultural identities. Responses were recorded and coded for multicultural orientation. Prior to administration, vignettes were vetted by experts in the field. Approximately 100 …

Nanoscale Thermal Transport In Thermally Isolated Nanostructures, Brian G. Green

Electronic Theses and Dissertations

Experiments with nanoscale structures, designed to measure some of their thermal and optical properties, are the subjects of this dissertation. We studied the transport of thermal energy in systems of nanoparticles, and used the method of transient thermoreflectance to monitor those dynamics, and assess whether thermal transport features special to nanoscale systems emerged. This same method was also used to study the thermal transport of a single system of layered membranes. Optical properties were investigated using computational simulations of a nanoparticle system, using the method of finite-difference time-domain simulation.

In nanoparticle studies, there are two features of interest special to …

Nonlinear Controller Design For Uavs With Time-Varying Aerodynamic Uncertainties, Michail G. Michailidis

Unmanned Aerial Vehicles (UAVs) are here and they are here to stay. Unmanned Aviation has expanded significantly in recent years and research and development in the field of navigation and control have advanced beyond expectations. UAVs are currently being used for defense programs around the world but the range of applications is expected to grow in the near future, with civilian applications such as environmental and aerial monitoring, aerial surveillance and homeland security being some representative examples. Conventional and commercially available small-scale UAVs have limited utilization and applicability to executing specific short-duration missions because of limitations in size, payload, power …

Conditions Affecting The Outcome Of Peace Operations In Post-Cold War Africa, Aaron Kyle Smith

Electronic Theses and Dissertations

What factors have led to successful outcomes in international peace operations conducted in Sub Saharan African countries? What factors explain mission failure? I proposed a basic theory of peace operations that linked conflict conditions to mandate design to the capability of an intervening force deployed for mission implementation developed from arguments and empirical results of previous research.

Data on 86 peace operations that occurred in 23 African states covering 33 separate conflict periods between 1990 and 2015 was analyzed. My main findings showed that mandates were derived from conflict assessments and determined the size of intervening force required. The results …

Disrupting Adultism: Practices That Enable Or Constrain Intergroup Contact Between Youth And Adults, Heather K. Kennedy

Electronic Theses and Dissertations

Background: The systematic subordination of young people who have little access to goods, resources, and power to make decisions is called adultism (Dejong & Love, 2015). Adultism has three components: attitudinal, institutional, and internalized. Attitudinal adultism, which is the focus of this dissertation, relates to adult's negative attitudes and beliefs regarding young people. Adultism intersects with other forms of oppression in after-school programs and likely impacts outcomes. Youth participatory action research (YPAR) is an orientation to knowledge production in which youth are positioned as experts in their own lives and work collectively with adults to identify an issue, collect data, …

Qualitative And Quantitative Fitness Consequences Of Advanced Maternal Age, Claudia Jean Hallagan

Electronic Theses and Dissertations

Parental age can affect offspring fitness across taxa and through various mechanisms. However, the effect(s) of advanced maternal age on offspring, particularly in insects, has not been comprehensively reviewed making it difficult to draw conclusions about the effects of advanced maternal age on offspring in insects. In my first chapter, I reviewed maternal age literature and found overall negative effects of advanced maternal age on offspring fitness. However, results vary depending on which fitness measures were used, the life stages at which offspring were measured, and the experimental design of the study. In my second chapter, I conducted an experiment …

Archaeological Computer Modeling Of Florida's Pre-Columbian Dugout Canoes: Integrating Ground-Penetrating Radar And Geographic Information Science, Brandon Ackermann

Electronic Theses and Dissertations

The focus of this research is the application of two computational methods in modeling pre-Columbian dugout canoe use on Florida's ancient transportation network. Ground-penetrating radar (GPR) was used to locate what appear to be multiple unexcavated canoes inundated in the lake-bottom of Lake Santa Fe, a lake in close proximity to Newnans Lake, which contains the largest number of ancient canoes in the world. The identification of multiple canoes in Lake Santa Fe supported the recent idea that this lake may have served as a transit point within Florida's pre-Columbian transportation network. A Geographic Information System (GIS) was then used …

Development Of A Hek293 Cell Line To Show Inhibition Of Tau Aggregation, Justin Ray Shady

Electronic Theses and Dissertations

Intracellular deposition of aggregated tau is the hallmark of several different tauopathies, the most widespread of these being Alzheimer's disease. Tau is a highly soluble, intrinsically disordered, microtubule associated protein. Tau's native function is to stabilize microtubule formation in the axons of neurons. Post translational modification such as hyperphosphorylation as well as several familial mutations allow tau to nucleate and form fibrils. These fibrils can recruit healthy monomers onto their ends in a fashion described as template-assisted growth. Tau has 6 isoforms that vary by the inclusion or exclusion of two N-terminal repeats and the inclusion or exclusion of the …

A Policy Mechanism For Federal Recommendation Of Security Standards For Mobile Devices That Conduct Transactions, Ariel Huckabay

Electronic Theses and Dissertations

The proliferation of mobile devices in the BRIC countries has prompted them to develop policies to manage the security of these devices. In China, mobile devices are a primary tool for payments. As a result, China instituted in 2017 a cyber security policy that applies to mobile devices giving China broad authority to manage cyber threats. The United States has a similar need for a cyber policy. Mobile devices are likely to become a primary payment tool in the United States soon. DHS has also identified a need for more effective security policy in mobile devices for government operations. This …

"Stretched Thin": Pregnancy And Motherhood In Clinical And Counseling Psychology Doctoral Programs, Kimberlee Yalango

Electronic Theses and Dissertations

Given that women now earn the majority of psychology doctoral degrees in the United States (Aud et al., 2012), there needs to be consideration of unique social and systemic difficulties that women may face during their studies. One particular issue of importance is women's choice to become pregnant and start families during their graduate education. Despite the challenges of becoming pregnant during a doctoral program and balancing the roles of mother and student, there has been limited research that examines this phenomenon. The purpose of this study was to understand the experiences of women who become pregnant during their time …

Preparing The Saudi Educational System To Serve The 2030 Vision: A Comparative Analysis Study, Wala'a Bunaiyan

Electronic Theses and Dissertations

Saudi Arabia's 2030 Vision (2019) aims to solidify the kingdom's influence in the Middle East while also diversifying the economy and increasing quality of life and access to opportunity for Saudis. One critical component of preparing Saudis for the job market is addressing low English language proficiency among students in the public school system (Rugh, 2002a, 2002b; Habbash, 2011; Elyas & Picard, 2011; Alrashidi & Phan, 2015). This study reviews existing literature on the Saudi Arabian educational system, the controversy surrounding English language instruction, and the importance of English for economic opportunity. Then, using transformative leadership (Shields, 2010) as the …

Evaluation Of A Sexual Health Training For Child Welfare Workers, Katie Massey Comsb

Electronic Theses and Dissertations

Background: Elevated rates of early pregnancy and parenting among youth in foster care (YFC) are well documented. Training child welfare workers to provide sexual health information and resources is stated throughout the extant literature as a pressing need in efforts to prevent unintended pregnancy among YFC. However, few child welfare agencies offer such training to their workers, and little is known about the extent to which conversations about sexual and reproductive health already occur between child welfare workers and youth. Thus, this study aimed to: a) assess baseline attitudes, knowledge, and communication among child welfare workers regarding sexual health of …
