Advancing Equity Amongst General Chemistry Students With Variable Preparations In Mathematics, Vanessa R. Ralph

USF Tampa Graduate Theses and Dissertations

Reducing the inequities propagating the lack of representation in Science, Technology, Engineering, and Mathematics (STEM) careers has become a national imperative made increasingly complex given the inequitable preparations in science and mathematics students experience before college. A common institutional-level approach to promoting equity is the use of math and science prerequisites to prepare students who seek to enroll in lower-level STEM coursework. However, the literature does not support the efficacy of this approach, finding no substantive improvement to student performance despite considerable financial and time costs to students, instructors, and universities alike. Set in first-semester General Chemistry courses taken early …

People With Parkinson’S And Care Partners Of Pwps’ Uncertainty Management Through Information Strategies, Amy Haywood

USF Tampa Graduate Theses and Dissertations

This thesis explores how people with Parkinson’s (PwP) and care partners of PwP manage the uncertainty surrounding Parkinson’s disease (PD). PD causes both motor and cognitive decline in patients, which may affect each individual differently (Williamson, Simpson, & Murray, 2008). There is no-known cure or cause for PD, meaning it is shrouded in uncertainty from the first symptom to the ongoing management process. This disease also affects care partners because of its variability in symptoms and progression. For this reason, this research, which is part of a larger study, interviewed both care partners of PwP (n= 10) and those diagnosed …

An Exploration Of Teachers’ Use Of Culturally Responsive Pedagogy, Ethic Of Care, And Reflectivity, Johan Von Ancken

USF Tampa Graduate Theses and Dissertations

A variety of educational reform literature discusses the “ethic of care” and “building relationships,” along with culturally relevant/responsive pedagogy (Gorski, 2013; Guajardo, M., Guajardo F., & Casaperalta, 2008; Ladson-Billings, 1992, 1995). In addition, “Appreciative Organizing in Education (AOE)” (Barrett & Fry, 2008; Burello, Beitz, & Mann, 2015; Cooperrider, Whitney, & Stavros, 2008) with its emphasis on strengths-based analysis of organizational change shaped my perception that a “Culture of Care” in our schools and with our teachers, administrators, and most importantly students, is necessary.

The notion of “culturally appropriate” (Au & Jordan, 1981, p. 139) pedagogy began over 35 years ago …

Asthma is a chronic condition that mainly affects adolescents. Recent reports from the Centers for Disease Control and Prevention (CDC) indicate a gradual increase in rates of lifetime asthma among adolescents from 17.1% in 2005 to 22.8% in 2015. Currently, one in ten adolescents nation-wide experience active asthma; similar trends are seen in the state of Florida (Florida Asthma Program, 2013; Centers for Disease Control and Prevention, Prevention, 2015). As a chronic, lifelong condition, asthma can be life-threatening if not properly controlled. When exacerbated, attacks of asthma constrict airways, leading to restrained breathing, wheezing, coughing and chest pain (Parulekar, Alobaidy, …

The Effect Of Acute Interpersonal Racial Discrimination On Smoking Motivation And Behavior Among Black Smokers, Patricia F. Calixte-Civil

USF Tampa Graduate Theses and Dissertations

In comparison to White smokers, Black smokers are more likely to report both discrimination and less success in smoking cessation. No previous study has tested the causal relationship between actual experienced racial discrimination and smoking variables associated with cessation. The goal of this study was to test the casual influence of interpersonal racial discrimination on smoking motivation (i.e., the urge to smoke cigarettes, cessation self-efficacy, and smoking behavior) using a controlled experimental design. We used a virtual ball-playing game to create a laboratory model of racial discrimination. A 2x2 between-subjects factorial design (inclusion/exclusion vs. ingroup/outgroup) was used to randomly assign …

Algorithms Enabling Communications In The Presence Of Adjacent Channel Interference, Berker Peköz

USF Tampa Graduate Theses and Dissertations

Newer cellular communication generations are planned to allow asynchronous transmission of multiple numerologies (waveforms with different parameters) in adjacent bands, creating unavoidable adjacent channel interference (ACI). Contemporary windowed-orthogonal frequency division multiplexing (W-OFDM) algorithms have limited ACI rejection capability under high delay spread and small fast Fourier transformation (FFT) sizes. CP is designed to be longer than the maximum excess delay (MED) of the channel to accommodate such algorithms in current standards. Most prior work on windowing assume additional extensions reserved for windowing, which does

not comply with standards. The robustness of these algorithms can only be improved against these conditions …

Trajectory Based Traffic Analysis And Control Utilizing Connected Autonomous Vehicles, Yu Wang

USF Tampa Graduate Theses and Dissertations

Recent scholars have developed a number of stochastic car-following models that have successfully captured driver behavior uncertainties and reproduced stochastic traffic oscillation propagation. While elegant frequency domain analytical methods are available for stability analysis of classic deterministic linear car-following models, there lacks an analytical method for quantifying the stability performance of their peer stochastic models and theoretically proving oscillation features observed in the real world. To fill this methodological gap, this study proposes a novel analytical method that measures traffic oscillation magnitudes and reveals oscillation characteristics of stochastic linear car-following models. We investigate a general class of stochastic linear car-following …

Teachers And Administrators Explain How And Why Teachers Change Instructional Methods In A Pre-K Through Eight Catholic School, Judith A. Deeley

USF Tampa Graduate Theses and Dissertations

This qualitative exploratory study explored how and why teachers at four small Catholic schools in the state of Florida transformed by changing instructional methods to offer full integration of science, technology, religion, engineering, arts and mathematics (STREAM) approaches into learning experiences for grades pre-k through eight. There was a time up until the early 2000s that Catholic school enrollment was at capacity and did not require differentiation based upon unique student learning needs. However, students of current times reflect a higher need for educational approaches that are both differentiated and engaging.
