Evaluation Of Low-Cost Low Impact Development Practices In Southwest Florida For The Control Of Urban Runoff, Laura Kathren Rankin

USF Tampa Graduate Theses and Dissertations

Stormwater management is required due to development and alteration of the natural environment. It is heavily regulated in Florida and at the national level. Over the last two decades, Low Impact Development (LID) has been promoted as a sustainable and environmentally friendly method of controlling urban runoff. Case studies, provided in Chapter 2, show that LIDs can restore watershed hydrology by balancing the water budget. The difference in runoff between pre-development and post-development appears to increase with soil perviousness. However, the potential for mitigating the impacts of urbanization through runoff reduction is also greater for pervious, sandy soils that dominate …

Effect Of Empathy On Death Penalty Support In Relation To The Racial Divide And Gender Gap, Brian Godcharles

USF Tampa Graduate Theses and Dissertations

This study aimed to examine previous empirical literature indicating that death penalty support contains a divide among Blacks and Whites and a gap among males and females. Previous literature has indicated that there has been a persistent racial divide and gender gap in death penalty support that has spanned over 60 years of research. Attempts to attenuate these divides have failed to fully explain why Whites are more likely than Blacks to support the death penalty and men are more likely than women to support the death penalty. This study proposes the use of empathy to control for these divides …

The Cultivation Of Eating Disorders Through Instagram, Kendall O'Brien

USF Tampa Graduate Theses and Dissertations

A profusion of research has been dedicated to the effects of new media on body image. In an attempt to explain the inflation of eating disorders, several researchers have turned to the cultivation theory, postulating that increased interaction with these medias will lead to internalizations of the messages they disseminate. The over presence of extremely thin models and actresses can create a new reality for media users, who begin to equate thinness with beauty, power, femininity and happiness. While an abundance of research has delved into the impact of this thin ideal through television and magazines, the Internet as a …

Pottery Exchange And Interaction At The Crystal River Site (8ci1), Florida, Kassie Christine Kemp

USF Tampa Graduate Theses and Dissertations

The Crystal River site (8CI1) is a Woodland-period mound (ca. 1000 BC to AD 1050) complex located on the west-central Gulf coast of Florida. Links to the Hopewell Interaction Sphere suggest that the people of Crystal River had connections with a broad range of communities, yet little is known concerning the role the site played in local, regional, or long-distance exchange networks. Pottery traditions vary amongst different communities of practice, therefore the level of interaction at Crystal River can be measured by looking at variation in the ceramic assemblage. I combine type/attribute, vessel form and function, gross paste, and chemical …

The Influence Of Negative Information On Trust In Virtual Teams, Tiffany T. Lee

USF Tampa Graduate Theses and Dissertations

Organizational work is characterized by positive as well as often negative work behaviors from employees. The same may be said of work done in virtual teams, where computer-mediated communication among team members can be particularly uncivil and inflammatory (Wilson, Straus, & McEvily, 2006). Accordingly, trust has been theorized as more difficult to develop in these types of teams compared to traditional face to face teams. Using a computer simulation of a collaborative team task, this study examined how individuals in virtual teams integrate conflicting pieces of positive and negative information about a teammate into one overall rating of trust. Data …

Trust In People And Trust In Technology: Expanding Interpersonal Trust To Technology-Mediated Interactions, Evgeniya Evgenieva Pavlova Miller

USF Tampa Graduate Theses and Dissertations

Trust is necessary for human interactions. It provides the ability to participate in risky behaviors without engaging in a laborious risk-benefit analysis about the situation at hand. The introduction of information and communication technologies has brought about new ways of communicating (e.g., text messaging, video conferencing). Despite the benefits stemming from the ability to communicate through technology, the lower quality and quantity of communication cues exchanged during a technology-mediated interaction can hamper the development of trust.

This study examined the relationship between interpersonal trust and trust in technology during a technology-mediated dyadic interaction and aimed to determine whether interpersonal trust …

Unpacking The Discipline Gap: Referral Categories And School-Wide Positive Behavior Interventions And Supports, Christopher Michael Barclay

USF Tampa Graduate Theses and Dissertations

Despite decades of efforts to racially integrate schools and the recent accountability movement, U.S. students’ access to equitable education remains elusive. Research demonstrates that discipline procedures disproportionately remove racial minority students from the classroom, creating a “discipline gap.” Racial disparities in discrete disciplinary infraction types (e.g., disruption, aggression) have shown nuanced patterns across groups and school levels. Moreover, the relationship between school-wide positive behavior interventions and supports (SWPBIS) – a framework for promoting positive behavior and preventing conflict – and the discipline gap is unclear. This investigation explored racial/ethnic disparities per infraction type (e.g. disruption, verbal abuse) and the relationship …

Characterization And Diurnal Measurement Of Oral Inflammation In Association With Glycemic Control, Periodontal Status, & Glucose Stimulation, Melanie N. Kuehl

USF Tampa Graduate Theses and Dissertations

Diabetes has afflicted 8.3%, approximately 25.8 million, of the United States population and is the seventh leading cause of death [1]. Type I diabetes (T1D) accounts for 5 to 10% of all diagnosed cases of diabetes in the United States [2]. If present trends continue, the rate of T1D incidence among children under the age of 14 will increase by 3% globally [3]. T1D is an autoimmune disorder in which the β-cells of the pancreatic islets are destroyed, leading to high blood sugar. Hyperglycemia and loss of immunological tolerance to self-antigens are common associations of T1D [4]. Periodontal disease impacts …

The Influence Of Types Of Homework On Opportunity To Learn And Students' Mathematics Achievement: Examples From The University Of Chicago School Mathematics Project, Yiting Yu

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Public views on assigning students mathematics homework have been controversial. Although homework is designed for students to complete during non-school hours (Cooper, 1989), many see homework as excessive pressure on students. Most research placed their focus on the influence of the time spent on homework or the amount of homework on student achievement. Few studies have addressed the impact of types of mathematics homework. The purpose of this study is to examine the role of homework types in influencing opportunity to learn (OTL) on student achievement.

This quantitative study used subsets of a large existing dataset collected by University …

The Experience Of Chronic Pain Management: A Multi-Voiced Narrative Analysis, Loren Wilbers

USF Tampa Graduate Theses and Dissertations

Since the late 1990s, the abuse of prescription opioid painkillers has been constructed as a major social problem in the United States, commonly referred to in the media as the “prescription painkiller epidemic.” Stories of addiction, overdose deaths, robberies, and other tragedies related to prescription opioids have been, and continue to be, commonly featured in the media. In response to public outcry regarding the “epidemic,” government and medical institutions have enforced strict regulations on the distribution of opioids, targeting most of these regulations at the treatment of chronic pain in particular. In this dissertation, I examine the experience of chronic …

Evaluation Of Soil As A Risk Indicator For Human Leptospirosis In Coastal, Rural Ecuador, Chad Allen Weddell

Essays On The Impact Of Ceo Gender On Corporate Policies And Outcomes, Nilesh Sah

USF Tampa Graduate Theses and Dissertations

In the first essay I examine the cash policies of female-led firms. Recent research finds that female CEOs eschew riskier corporate policies, but it makes contradicting claims whether this is due to risk aversion. Benchmarking risk aversion by the management of firms’ cash, I find that female CEOs are risk averse relative to male CEOs. Specifically, they hold significantly (18%) more cash, even for the same level of dividend payout as male CEOs. Further, they have significantly higher speed of adjustment for cash deficits, are more likely to use excess cash to increase dividends, but are equally likely to use …
