Using Optimization Methods For Solving Problems In Sustainable Urban Mobility And Conservation Planning, Zulqarnain Haider

USF Tampa Graduate Theses and Dissertations

This dissertation considers three separate optimization problems related to sustainable urban and environmental systems. The first problem relates to the nightly relocation and recharging operations for Free-floating electric vehicle sharing (FFEVS) systems. Such operations involve a crew of drivers to move the shared electric vehicles (EVs), and a fleet of shuttles to transport those drivers. Mixed integer programs are used to model the relocation and recharging operations. Two approaches are devised: sequential and synchronized approaches. In the sequential approach, the movement of EVs is first decided, then the routing of shuttles and drivers is determined. In the synchronized approach, all …

Changing The Culture Of Consent: Teaching Young Children Personal Boundaries, Marlesha C. Bell

USF Tampa Graduate Theses and Dissertations

Currently, eight states and Washington D.C. mention consent education in their sex education standards (Naide, 2020). Most school-based consent education curricula focus on teaching pre-teens through adults consent within the context of sexual contact (Planned Parenthood, 2016). However, consent may be relevant for behavior outside the context of sexual contact. Young children could develop a repertoire for consent skills and use it to set and respect boundaries. Furthermore, behavior analysis has teaching technologies that could be used to inform a curriculum for teaching consent, such as behavioral skills training (Johnson et al., 2006) and video modeling (Charlop & Milstein, 1989). …

Temporal Discounting And The Assessment And Treatment Of Academic Procrastination, Anthony Concepcion

USF Tampa Graduate Theses and Dissertations

Many individuals engage in procrastination at some point in their lifetime. Although procrastination is usually not detrimental, for college students, academic procrastination is correlated with adverse health effects (e.g., anxiety, depression, sleep hygiene) and poor academic performance (Akinsola, et al., 2007; Ferrari, et al., 1995). Furthermore, the prevalence of academic procrastination is high with reports of up to 95% of college students engaging in detrimental amounts of procrastination (Hussain & Sultan, 2010). Notably, students enrolled in online courses are likely to be at greater risk to experience adverse consequences associated with procrastination (Elvers, et al, 2003). Previous studies have focused …

Early Adolescents' Basic Psychological Need Satisfaction And Frustration, Motivation, And Verbal Divergent Thinking Within An Out-Of-School Context, Megan Louise Atha

USF Tampa Graduate Theses and Dissertations

Early adolescence is a vital time for the development of creative thinking and behaviors (Barbot et al., 2016) as well as for examining factors that influence the motivation of youth to engage and persist in creative processes and to develop creative abilities (Beghetto & Dilley, 2016). In order to support the motivation towards creative pursuits that may be unique to early adolescent youth, the satisfaction of basic psychological needs for competence, autonomy, and relatedness may be important. Since out-of-school contexts are an increasingly important element of adolescents’ day-to-day experiences, research that investigates how contextual factors contribute to the development of …

A Health Evaluation Of Gulf Of Mexico Golden Tilefish (Lopholatilus Chamaeleonticeps) And Red Snapper (Lutjanus Campechanus) Following The Deepwater Horizon Oil Spill, Kristina Leigh Deak

USF Tampa Graduate Theses and Dissertations

A lack of baseline heath indices for offshore Gulf of Mexico (GoM) teleosts complicated impact assessments of the Deepwater Horizon (DWH) oil spill. While measurement of contaminant levels in fish after a pollution event can document exposure, such data fail to provide meaningful information about how this contact affects an animal's physiology. Controlled exposure studies have highlighted the utility of biomarkers that may indicate deleterious, long-lasting effects of pollutant exposure on various life stages of fish, however, their extrapolation to wild-caught, non-model species is challenging. In an increasingly chemically-saturated environment, it can also be difficult to separate the influence of …

Development Of An Integrated Direct Membrane Filtration (Dmf) And Anaerobic Membrane Bioreactor (Anmbr) System For Dilute Municipal Wastewater Treatment, Ahmet Erkan Uman

USF Tampa Graduate Theses and Dissertations

The total electricity consumption due to municipal wastewater treatment in the US accounts for 1.3% of total demand. Also, a significant portion of biodegradable constituents in wastewater is converted into biomass, which needs further processing. On the one hand, an excessive amount of energy and chemicals are being used to treat wastewater, but on the other hand, resources (such as nitrogen and phosphorus, energy, and water) in wastewater are being discharged or removed rather than recovered. From this perspective, new wastewater treatment technologies are sorely needed to facilitate resource recovery from wastewater for a better, more sustainable future.

Anaerobic membrane …

"You Want To Teach What?" An Examination Of Physical Education Teacher Candidates' Motivation To Teach Physical Education, Rebecca C. Wylie

USF Tampa Graduate Theses and Dissertations

This study examined the reasons individuals choose to become physical educators. Understanding these PE teacher candidates’ motivating factors for choosing this career is important as nearly half of all new teachers will leave the profession within the first three years of teaching (Ensign & Mays Woods, 2017). Using the theoretical framework of Deci and Ryan’s self-determination theory, (1984) motivation levels of the PE teacher candidates’ were also examined. For this study, six PE teacher candidates answered both the Attractors and Facilitators for Physical Educators questionnaire and the Academic Motivation Scale. The participants also participated in two semi-structured interviews examining their …

Care In Context: Constructing A Theory Of Care In One Fifth Grade Classroom, Emily J. Wingate

USF Tampa Graduate Theses and Dissertations

With a culmination of evidence suggesting the perception of caring relationships is associated with students' well-being (Natvig, Albrektsen, & Qvarnstrøm, 2003; Siddall, Huebner, & Jiang, 2013; Suldo, Friedrich, White, Farmer, Minch, & Michalowski, 2009), there is a need to better understand the ways in which care operates in the classroom. Further, there is a need to move beyond a prescription of caring behaviors to investigate the ways in which care, control, and conflict interact to impact classroom relationships. In the current study, I took a mini-ethnographic case study approach to investigate the concept of care within one fifth grade classroom. …

Evaluating Public Posting, Goal Setting, And Rewards To Increase Physical Activity In Children, Bryon G. Miller

USF Tampa Graduate Theses and Dissertations

In Experiments 1 and 2 we evaluated a pedometer-based intervention consisting of public posting between two teams of students, with additional self-monitoring, goal setting, and reinforcement components, to increase physical activity during school recess. In the absence of self-monitoring, performance feedback alone did not increase physical activity levels above those observed during baseline. Additionally, higher levels of physical activity were observed when goal-setting was introduced, with the highest levels of activity observed when raffle tickets could be earned for exceeding a specified step-total goal. In Experiment 3 we removed the team component and evaluated similar intervention components across an entire …

School of Geosciences Faculty and Staff Publications

The observed movements of humans and animals are realizations of complex spatiotemporal processes. Recent advances in location-aware technologies have rendered trajectory data ubiquitous. Examining the sequenced, instantaneous locations found in movement trajectory data for information reconstructing the location or state of the mover between observed points comprises a primary focus in Time Geography and related disciplines. The PySTPrism toolbox introduced in this paper provides a straightforward and open-source implementation of the Probabilistic Space Time Prism, in addition to related tools from Time Geography. PySTPrism is implemented in Python using the ArcPy module in ArcGIS Pro Desktop.

Effects Of Inter-Male Status Challenge And Psychopathic Traits On Sexual Aggression, Amy M. Hoffmann

USF Tampa Graduate Theses and Dissertations

Sexual aggression (SA) is a serious social problem that has been linked to a variety of negative physical and mental health outcomes for survivors and produces significant monetary costs to society. In the past five decades, a wealth of research has improved our understanding of the individual and sociocultural factors that contribute to SA perpetration; however, epistemological differences in theoretical approaches to the subject (i.e., evolutionary, feminist) have resulted in gaps in the empirical literature. Informed by both feminist and evolutionary perspectives, this study attempts to examine the ways in which same-gender interpersonal interactions and individual psychopathology interact to produce …

Competition In Upstream Humanitarian Supply Chain: Investigation Of Food Banks, Iana Shaheen

USF Tampa Graduate Theses and Dissertations

Global hunger is not about a shortage of food. Currently, the world generates enough food to sustain every man, woman, and child on the planet. However, in 2018, about 815 million people, or almost 11% of the population, were hungry worldwide (World Hunger Report, 2018). To respond to the problems in ways more adapted to the requirements of people in need, humanitarian organizations (HOs) are dedicated to becoming more effective and efficient (Weiss, 2013). With the boost in the number of people that require humanitarian assistance, the number of HOs is increasing each year. As a result, there is unanimity …

Developing A Taxonomic Framework Of Security Methods For Security Management And Information Resource Management, Yejun Wu

Journal of Strategic Security

People who are concerned with security (such as security professionals) are naturally interested in methods of achieving security. This paper proposes an approach to creating a taxonomic framework of security methods. The taxonomic framework is developed using facet analysis based on a tetra-facet model of security, which identifies four facets of security: subject/scope of security, object of protection, source of insecurity, and method of protection. The taxonomic framework of security methods is created by combining two of the facets: source of insecurity and method of protection. The taxonomic framework of security methods can be integrated with the taxonomic framework of …

Active Deep Learning Method To Automate Unbiased Stereology Cell Counting, Saeed Alahmari

USF Tampa Graduate Theses and Dissertations

Cell quantification in histopathology images plays a significant role in understanding and diagnosing diseases such as cancer and Alzheimers. The gold-standard for quantifying cells in tissue sections is the unbiased stereology approach. Unfortunately, in unbiased stereology current practices rely on a well-trained human to manually count hundreds of cells in microscopy images. However, this human-based manual approach is time-consuming, labor-intensive, subject to human errors, recognition bias, fatigue, variable training, poor reproducibility, and inter-observer error. Thus, the lack of high-throughput technology for automating unbiased stereology analyses remains a major obstacle to further progress in a wide range of neuroscience and cancer …

These programs are designed to assist former foster youth through an array of services, which range from financial aid to mentorship. However, little is known about how these programs are designed or implemented, or how effectively they are meeting the needs of this population. This dissertation sought to build upon previous research that examined the barriers faced by former foster children who are pursuing a …

Assisted Living Facilities In Florida: Examining The Factors Associated With Entries, Closure, And Licensure Change, Joseph W. June

USF Tampa Graduate Theses and Dissertations

Assisted living facilities (ALFs) have become a large provider of long-term care in the United States. Their expansion has been met with interest from older adults who desire to be independent yet receive some services and from state legislators who recently have attempted to increase access. Studies in long-term care have focused extensively on nursing homes, but recent research has examined the effects of ALFs on the long-term care market. Research has been lacking in understanding the unique markets of ALFs. Describing themselves as “communities” and offering multiple options for housing, ALFs have targeted independent and wealthier older adults who …
