There are mixed findings regarding the effect of bilingual exposure on the development of adaptive, social, communication, and cognitive skills of children with ASD (e.g., Hambly & Fombonne, …

School Nurses’ Attitudes And Perceptions Toward Supporting Students With Chronic Health Conditions In An Ecological System, Destiny L. Singleton

USF Tampa Graduate Theses and Dissertations

Chronic health conditions impact one in four school-aged youth (Van Cleave, Gortmaker, & Perrin, 2010). Supplemental to the medical challenges that students with chronic health conditions face, they also are at risk for a variety of academic, behavioral, and social-emotional adversities. Using an ecological approach for addressing the diverse needs of students with chronic health conditions has been deemed valuable due to the array of key stakeholders, institutions, policies, and cultural norms that impact the development of the pediatric population. A key stakeholder in supporting the functioning of school-aged children with chronic illnesses is the school nurse. School nurses’ skills …

Predictors Of Goal Attainment Among High School Students In Accelerated Academic Curricula Receiving School-Based Motivational Interviewing Intervention, Camille E. Hanks

USF Tampa Graduate Theses and Dissertations

Students enrolled in Advanced Placement (AP) courses and International Baccalaureate (IB) programs represent a unique group of adolescents given the high demands of their rigorous coursework and the elevated stress they experience compared to peers in the general education (Suldo & Shaunessy-Dedrick, 2013). These students are often missed in traditional screening procedures that tend to identify students struggling academically or exhibiting disruptive behaviors. Fortunately, Shaunessy-Dedrick and colleagues (2021) developed a comprehensive school-based intervention program, including universal (Tier 1) and selective (Tier 2) components, which aims to support the well-being of AP/IB students. The Tier 2 component of this program (i.e., …

Biochar Amended Bioretention Systems For Nutrient And Fecal Indicator Bacteria Removal From Urban And Agricultural Runoffs, Md Yeasir Arif Rahman

USF Tampa Graduate Theses and Dissertations

Excessive nitrogen and fecal indicator bacteria (FIB) in stormwater runoff from urban areas or dairy farm operations impair water bodies resulting algal blooms, gastrointestinal illness, and economic losses. Recent advancements in stormwater management, including low impact development (LID) techniques, have provided engineers with a variety of tools to use in place of traditional catch basins and retention ponds. One promising LID technology for runoff management is bioretention, which consists of a shallow depression containing engineered porous media and vegetation.

Development And Testing Of The Performance Diagnostic Checklist For Instructors, Jesse Depaolo

USF Tampa Graduate Theses and Dissertations

Behavior analysts have been studying behavior related to academic instruction for decades (Dunlap et al., 2001). Instruction has focused primarily on K-12 teachers with much less emphasis on college level instructors (Baum & McPherson, 2019). Additionally, studies related to improving instruction often lack information related to why a particular intervention was chosen. Creating an assessment tool to assist in determining interventions that would be most effective for improving classroom or virtual instruction could be beneficial. Therefore, the purpose of study one was to develop the Performance Diagnostic Checklist for Instructors (PDC-I) which will help guide supervisors of college instructors into …

The Use Of Data Analytic Visualizations To Inform The Audit Risk Assessment: The Impact Of Initial Visualization Form And Documentation Focus, Rebecca N. Baaske (Becca)

USF Tampa Graduate Theses and Dissertations

Although data analytic technologies provide auditors with powerful tools for identifying high-risk areas during an audit (Austin, Carpenter, Christ, and Nielson 2019), they are not a substitute for necessary interpretation and judgment (Brown-Liburd, Issa, and Lombardi 2015). A major barrier for making better use of data analytic techniques and tools is the skillset needed to make necessary interpretations and judgments based on data visualizations within the tool (Appelbaum, Kogan, and Vasarhelvi 2017; Earley 2015; PwC 2015). Default visualizations provided to auditors could be suboptimal in relation to the underlying data, which could limit auditors’ ability to identify anomalies without some …

Haptics is an interdisciplinary field of science that deals with how humans perceive and respond to different sensory cues perceived through touch. Thermal haptics as a branch deals with how humans perceive the temperature sensation and respond to that. The process in which thermal perception occurs is well known to researchers. What seems missing in the literature is how temperature interacts or sometimes intervenes in other physiological and psychological aspects of our lives. In this research, a series of studies are presented where the main focus was how temperature and brain interact with each other to impede or enhance our …

Targeting Modern Pathogens With Rational Drug Design, Michael Dominic Sacco

USF Tampa Graduate Theses and Dissertations

Since the first living organisms appeared on earth, their very existence was dependent on their ability to contend for resources. To this day, organisms are perpetually competing for resources, and in doing so, have evolved highly effective defense mechanisms and systems for propagation. Although invisible to the eye, we live in a world teeming with microbes and viruses. While many are harmless, others cause widespread disease. One of the key niches for these pathogens, particularly bacteria, are health-care facilities. These health-care facilities have a high concentration of immunocompromised patients and rely heavily on antibiotics, which strongly contributes to antibiotic resistance. …

Event-Triggered Control Architectures For Scheduling Information Exchange In Uncertain And Multiagent Systems, Stefan Ristevski

USF Tampa Graduate Theses and Dissertations

Despite the numerous advantages that networked controlled systems provide, potential network overload in these systems can severely degrade their performance and even cause catastrophic failures. To this end, the work presented in this dissertation provides a neat solution on reducing network utilization in uncertain networked controlled systems using an adaptive event-triggered control approach predicated on a novel dynamical threshold and information exchange methodology while guaranteeing closed-loop system stability.

In particular, consider a system consisting of an operator (e.g, a ground station) and an uncertain controlled dynamical system (e.g., a vehicle equipped with feedback control algorithm), where the aim of the …

Transcriptomic And Functional Investigation Of Bacterial Biofilm Formation, Brooke R. Nemec

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus and Acinetobacter baumannii are two highly successful human pathogens, which have adopted very different, but effective survival strategies. The success of S. aureus is attributed to the tight regulation of an arsenal of virulence factors. Conversely, A. baumannii lacks what would be considered traditional virulence factors and, instead, has developed a high tolerance for environmental stress, which allows it to persist in unforgiving environments, including nosocomial settings and the human body. One common characteristic of these two organisms is their proclivity for biofilm formation. Herein, we discuss the diverse mechanisms governing biofilm formation for A. baumannii and S. …
