An Investigation Into The Protein Dynamics And Proton Transfer Mechanism Of Class-A Β-Lactamase (Ctx-Ms) By Nmr Spectroscopy, Radwan Ebna Noor

USF Tampa Graduate Theses and Dissertations

Extended-spectrum β-lactamases (ESBLs) of different Enterobacteriaceae (e.g. Escherichia coli, Klebsiella pneumoniae) have developed significant resistance mechanisms against antibiotics. ESBLs, like class A CTX-Ms (cefotaximases) enzymes hydrolyze the β-lactam ring of different antibiotics such as penicillins and third-generation oxyimino-cephalosporins. Although CTX-Ms are repeatedly found in many clinical and community settings, molecular-level information on their function/activity is currently limited to structural studies performed by X-ray crystallography. In order to gain further insights into the structure and functions of this class of proteins, it is also essential to fully understand their dynamic and chemical properties in solution. In order to better understand the …

A Comparison Of Accumulated And Distributed Reinforcer Arrangements In A Classroom, Alexandra Gingras

USF Tampa Graduate Theses and Dissertations

Though effective classroom management can increase student academic achievement and decrease disruptive behavior (e.g., Beaman & Wheldall, 2000; Marzano et al., 2003), many classroom teachers receive inadequate training on effective classroom management strategies (Reinke et al., 2011; U.S. Department of education 2000). Reinforcement-based interventions using differing reinforcer arrangements (e.g., accumulated, distributed) have been shown to be effective at reducing disruptive behavior (Fulton et al., 2019; Robinson & St. Peter, 2019); however, previous studies have not evaluated the relative efficacy of different reinforcer arrangements as teacher implemented classroom management strategies. Therefore, the purpose of this study was to assess the efficacy …

Self-Perceived Assessment Of Undergraduate Leaders Competencies Through A Leadership Development Program, Ryan D. Newton

USF Tampa Graduate Theses and Dissertations

This ex-post facto research study identified changes in participants’ self-perceptions of their competence in six key leadership competencies, as reported from a pre-training and post-training self-assessment. This study also identified the relationship between the participants’ self-reported changes and their persistence in enrollment at the University upon completion of the leadership training program. This quantitative study analyzed secondary data (N=201) from a large, four-year, public research institution in the southeast United States. Paired samples t-tests were used to determine that the self-reported change among participants was statistically significant (p<.05) from the pre- to the post-training self-assessment. Further, this study then examined the relationship between participants’ self-reported mean change and their persistence at the institution, defined as having graduated or continuing enrollment one year after completion of the leadership training program. A logistic regression was utilized to identify a negative predictive relationship between participants’ mean change and their likelihood of persistence. Implications for competency-based learning were discussed in relationship to student affairs practice.
