The Role Of Rater Motivation In Personnel Selection Validation Studies, Dan Ispas

USF Tampa Graduate Theses and Dissertations

Personnel selection validation studies are routinely conducted in contemporary organizations for selecting and placing employees. Although numerous studies have been conducted with the goal of identifying new predictors, less research was focused on the criterion side. In the current paper, across three studies and five samples, I examined the role played by rater motivation in validation studies. I proposed that rater motivation would impact criterion-related validity of various predictors, the reliability, and the variance of performance ratings. In Study 1, these hypotheses were tested in two samples with varied operationalizations of predictors and of rater motivation. In Study 2, I …

The Positive- And Negative-Right Conceptions Of Freedom Of Speech And The Specter Of Reimposing The Broadcast Fairness Doctrine ... Or Something Like It, Adam Fowler

USF Tampa Graduate Theses and Dissertations

A key theoretical debate underlying the now defunct Federal Communications Commission (FCC) regulation known as the Fairness Doctrine is conflict over what constitutes the right to freedom of speech: a positive or negative conception. Similarly, since repeal of the Doctrine, other FCC measures to uphold the “public-interest” standard in broadcasting have relied on a positive conception of speech. This thesis demonstrates the history of this debate through court cases, news reports, scholarly articles and historical documents. It then is argued that the positive-right nature of these regulations is problematic philosophically, constitutionally and practically. The positive-right conception lends itself to an …

Identifying And Addressing Health Disparities In Black Older Adults With Osteoarthritis, Chivon A. Mingo

USF Tampa Graduate Theses and Dissertations

Osteoarthritis (OA), the most common form of arthritis in older adults, often results in pain, disability and poor psychological well-being. Compared to White adults, Black adults consistently report more pain, more activity limitations, and have different perceptions about OA. Racial disparities also exist in treatments, and prevalence of arthritis. It is imperative to have effective interventions and treatment options for older Blacks. Yet, few arthritis interventions have included Black participants in their samples, and nearly all of those have failed to report separate analyses indicating the effectiveness for Black adults, thus leaving a gap in the literature. The purpose of …

Trials And Verdicts: Narratives Of Recollection In The Good Soldier And Lolita, Constance Elizabeth Holmes

USF Tampa Graduate Theses and Dissertations

This dissertation will apply the structure of a legal trial’s procedures to two Modernist novels: Ford Madox Ford’s The Good Soldier (1915) and Vladimir Nabokov’s Lolita (1955). These novels position themselves as renderings of legal proceedings, the written memoriam of metaphorical trials conducted by first person narrators who alternatively and simultaneously function as Plaintiff’s counsel, Defense Counsel and finally as witnesses to the events of the story. All of these personae reveal evidence and testimony presented in the forum of a trial of the central characters who recollect legal events and whose narrations develop moral questions. Thus these narrations are …

Modeling And Analysis Of Cooperative Search Systems, Carlos A. Portilla

USF Tampa Graduate Theses and Dissertations

The analysis of performance gains arising from cueing in cooperative search

systems with autonomous vehicles has been studied using Continuous Time Markov

Chains; where the search time distributions are assumed to follow the exponential

distributions. This work proposes the use of Petri Nets to model and analyze these

systems. The Petri Net model considers two types of autonomous vehicles: a search-only

vehicle and n search-engage vehicles. Specific performance metrics are defined to

measure system’s performance. Through simulation, it is shown that the search time with

stationary targets and cues that provide exact target location follows a triangular

distribution. A methodology …

How Does Mobility Change Over Time For Older Adults, And How Are Changes Influenced By Cognitive Functioning?, Melissa Lunsman O'Connor

USF Tampa Graduate Theses and Dissertations

Mobility, which includes life space and driving behaviors, is an important functional domain for older adults (e.g., Webber, Porter, & Menec, in press). Low mobility is associated with sensory, physical, and cognitive deficits (e.g., Anstey, Wood, Lord, & Walker, 2005). However, few studies have investigated how mobility changes over time. This dissertation contains three longitudinal articles that explored mobility changes, with an emphasis on driving and cognition, among community-dwelling older adults.

The first paper investigated patterns of driving self-regulation (i.e., adjustment of driving behaviors) among control-group participants from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study (N=548). …

Upper Elementary Boys’ Participation During Group Singing Activities In Single-Sex And Coeducational Classes, Zadda M. Bazzy

USF Tampa Graduate Theses and Dissertations

As boys in the upper elementary grades become increasingly influenced by peer pressure, many are less likely to participate in singing activities because singing is considered a "feminine" activity. The purpose of this research was to explore if there was an effect on upper elementary boys' level of participation during group singing activities when they attended music classes in a single-sex setting.

This study employed a true experimental design and a mixed method. Boys (N = 186) were videotaped during their regular coeducational music classes on two occasions to establish baseline data. Then the students were randomly assigned to …

Self-Potential Response To Rainfall Changes Over Plugged And Unplugged Sinkholes In A Covered-Karst Terrain, Peter B. Bumpus

USF Tampa Graduate Theses and Dissertations

For the protection of wetland and water resources it would be beneficial to understand when collapse conduits function as recharge points to the underlying aquifer. Inexpensive, noninvasive methods to detect recharge are desirable. Previous studies show negative self-potential (SP) anomalies over sinkholes that correspond to the expected electrokinetic effects of groundwater flowing downward through a conduit. SP surveys are less labor-intensive than high-resolution 3D GPR and resistivity, and continuous long-term monitoring is possible. However, before SP surveys can be reliable indicators of flow, SP contributions from ET, conductivity changes, redox reactions, thermoelectric effects, cultural noise, and lateral flow must be …

Influence Of Misperceptions About Gay Affluence On Support For Pro-Gay Legal Reform, Vanessa E. Hettinger

USF Tampa Graduate Theses and Dissertations

The deleterious impact of negative stereotypes toward gays has been established, but less thoroughly examined are the potentially harmful effects that positive stereotypes may carry. Gay Americans lack multiple legal rights enjoyed by heterosexual citizens, yet many people do not see gays as a genuinely disadvantaged group. One possible reason for this is the popular misconception that gays are wealthier than the average American. Drawing on previous research regarding popular support for underdogs, it was predicted that, to the extent people endorsed the conception of gay affluence, they would be less likely to support legal reform benefiting gays. This hypothesis …

The Relationship Between Life Satisfaction And Substance Use In Adolescence, Leeza Rooks

USF Tampa Graduate Theses and Dissertations

Low life satisfaction and substance use in adolescence are causes for concern as each problem is known to be associated with many concurrent and later negative outcomes. To date, only four studies have examined links between these variables in youth. This study added to the literature by examining adolescents' life satisfaction in relation to their frequency of use of a variety of substance types, using an understudied population (i.e., a predominantly Hispanic sample of 130 high school students). Results included significant, inverse bivariate links between adolescent life satisfaction and use of alcohol, cigarettes, and marijuana. When examined simultaneously, adolescents' use …

Victimization Among Individuals With Low Self-Control: Effects On Fear Versus Perceived Risk Of Crime, Casey Williams

USF Tampa Graduate Theses and Dissertations

Fear of crime is an issue that has long been a part of mainstream society through politics and media. However, research on the specific mechanisms of fear and the effects on behavior is sparse. After considering the victim-offender overlap consistently found within the literature, the present study was based on the theory posed within Schreck, Stewart, and Fisher (2006) in which those who are low in self-control may have altered perceptions of fear or risk of crime that might increase the likelihood that the individual will be in risky locations conducive to victimization. The current study also included a novel …

A Case Study Examining The Impact Of Adventure Based Counseling On High School Adolescent Self-Esteem, Empathy, And Racism, Chris Cale

The goals of this study were to (a) explore the effectiveness of ABC Counseling in increasing levels of self-esteem and empathy among adolescents; (b) study the efficacy of ABC counseling in reducing perceived racial discrimination, racist attitudes, or both; and (c) investigate the correlation between self-esteem, empathy, perceived racial discrimination, and racist attitudes as related to the effects of ABC counseling. In addition, the effects of ABC counseling on the school-related variables such as discipline, attendance, and academics, as well as possible outcome differences caused by demographic …

Modeling And Experimentation Of Micro-Scale Self-Assembly Processes, Gary Hendrick

USF Tampa Graduate Theses and Dissertations

Self-Assembly in the context of micro-scale integration refers to a developing set of techniques which exploit phenomena resulting in the spontaneous integration of micro-scale components into designed systems. Self-Assembly may be leveraged most effectively in parallel assembly processes. This thesis studies the modeling of micro-scale self-assembly processes as stochastic processes. The researchers propose that self-assembly processes may be modeled as Markov chains. In order to develop these models a Self-Assembly test system was created and trials were conducted using this system. Initial tests into the hypothesis that variables contributing to the transition probabilities include the kinetic energy of the assembly …

Fluorescence Molecular Tomography: A New Volume Reconstruction Method, Stephen Joseph Shamp

USF Tampa Graduate Theses and Dissertations

Medical imaging is critical for the detection and diagnosis of disease, guided biopsies, assessment of therapies, and administration of treatment. While computerized tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and ultra-sound (US) are the more familiar modalities, interest in yet other modalities continues to grow. Among the motivations are reduction of cost, avoidance of ionizing radiation, and the search for new information, including biochemical and molecular processes. Fluorescence Molecular Tomography (FMT) is one such emerging technique and, like other techniques, has its advantages and limitations. FMT can reconstruct the distribution of fluorescent molecules in vivo using near-infrared …

A Survey Of The Development Of Daubechies Scaling Functions, Amber E. Age

USF Tampa Graduate Theses and Dissertations

Wavelets are functions used to approximate data and can be traced back to several different areas, including seismic geology and quantum mechanics. Wavelets are applicable in many areas, including fingerprint and data compression, earthquake prediction, speech discrimination, and human vision. In this paper, we first give a brief history on the origins of wavelet theory. We will then discuss the work of Daubechies, whose construction of continuous, compactly supported scaling functions resulted in an explosion in the study of wavelets in the 1990's. These scaling functions allow for the construction of Daubechies' wavelets. Next, we shall use the algorithm to …

Low-Level Programming Of A 9-Degree-Of-Freedom Wheelchair-Mounted Robotic Arm With The Application Of Different User Interfaces, Punya A. Basnayaka

USF Tampa Graduate Theses and Dissertations

Implementation of C++ and Matlab based control of University of South Florida's latest wheelchair-mounted robotic arm (USF WMRA-II), which has 9 degrees-of-freedom, was carried out under this Master's thesis research. First, the rotational displacements about the 7 joints of the robotic arm were calibrated. It was followed by setting the control gains of the motors. Then existing high-level programs developed using C++ and Matlab for USF WMRA-I were modified for WMRA-II. The required low-level programs to provide complete kinematics of the joint movements to the controller board of WMRA-II (Galil DMC-2183) were developed using C++. A test GUI was developed …

Human Factors Consideration In Developing A New Drive-By-Wire Interface, Sravan Kumar Elineni

USF Tampa Graduate Theses and Dissertations

The current study examined specific aspects of human factors involved in driving a vehicle with a modified Drive-by-Wire (DBW) control system. A DBW system is an electro-mechanical system which controls the primary operations of a vehicle such as steering, acceleration, and braking using a controller such as a joystick. Designing a human interface system for a DBW system involves three main phases in the human factors design process namely user centric/ergonomic design conception, building a prototype and validating the prototype based on human factor considerations. The main objective and focus of this research is to conceptualize a more ergonomic DBW …
