Doing Dignity At The Grace Café: An Ethnographic Exploration Of A Homeless Outreach Program, Courtney A. Glover Apr 2008

Doing Dignity At The Grace Café: An Ethnographic Exploration Of A Homeless Outreach Program, Courtney A. Glover

USF Tampa Graduate Theses and Dissertations

Homeless outreach programs vary widely in their approaches to client treatment. At the Grace Café, an organization that serves daily meals to people who are homeless, the concept of dignity is central to guest treatment. According to the café's ideology, the importance of providing food is secondary to serving with dignity. This research explores dignity as an ideal of client treatment at the Grace Café. Based on ethnographic research, this paper explores how dignity is communicated to volunteers, implemented in service, and challenged at the Grace Café.

Cost-Effectiveness Of Epidural Steroid Injections To Treat Lumbosacral Radiculopathy In Chronic Pain Patients Managed Under Workers’ Compensation, Sheila Mohammed

USF Tampa Graduate Theses and Dissertations

No conclusive evidence exists to determine that epidural steroid injections (ESIs) provide lasting improvements in chronic pain due to herniated discs, in the Workers' Compensation population. Recently, an article by Armon et.al was published by the American Academy of Neurology, which stated that the routine use of ESIs is not recommended and that further studies are needed to elucidate this controversy (Armon, Argoff, Samuels, & Backonja, 2007).

In 1998, back pain in the United States was estimated to have incurred total health-care expenditures of $90.7 billion. Medicare part B. claims in 1999 for 40.4 million individuals amounted to $49.9 million …

Organizational Culture In Children's Mental Health Systems Of Care, Jessica Mazza Apr 2008

Organizational Culture In Children's Mental Health Systems Of Care, Jessica Mazza

USF Tampa Graduate Theses and Dissertations

A cohesive organizational culture has been linked to positive outcomes in child-serving agencies, such as improved child-level outcomes and positive organizational climate (Glisson & Green, 2006; Glisson & Hemmelgarm, 1998; Glisson & James, 2002; Hemmelgarn, Glisson, & James, 2006). Although isolated studies of organizational culture have been conducted in individual agencies (child welfare and juvenile justice), no study has examined the organization culture of successful, holistic systems of care that involve the coordination of multiple agencies, such as child welfare, juvenile justice, mental health and education. Data collected from the three system-of-care sites selected for participation in Case Studies of …


Digitally Implemented Interactive Fiction: Systematic Development And Validation Of “Mole, P.I.”, A Multimedia Adventure For Third Grade Readers, Denise Haunstetter Apr 2008

Digitally Implemented Interactive Fiction: Systematic Development And Validation Of “Mole, P.I.”, A Multimedia Adventure For Third Grade Readers, Denise Haunstetter

USF Tampa Graduate Theses and Dissertations

"Interactive fiction" has been used to describe many of today's multimedia products. In reality, there is not a universal understanding of what interactive fiction is or what it should entail. The meaning of "interactive" is often interpreted in different ways. Many stories are considered to be interactive because they are placed on the computer. Meanwhile, such stories may lack most of the essential qualities for good literature. Interaction fiction should be upheld to the same standards as traditional texts. Following this belief, this research covers the underlying theories of interactive fiction, examples of misleading "interactive fiction" studies, and guidelines for …

These intriguing properties of PNA implicated great potential for medical and biotechnical applications. Therefore, PNA has attracted many scientists in the fields of chemistry, biology, medicine including drug discovery and genetic diagnostics, …


Comparing A Low-Volume Piezometer To Traditional Wells In Evaluating Hydraulic Lag Caused By Low-Permeability Sediments, John M. Spencer Apr 2008

Comparing A Low-Volume Piezometer To Traditional Wells In Evaluating Hydraulic Lag Caused By Low-Permeability Sediments, John M. Spencer

USF Tampa Graduate Theses and Dissertations

Traditionally-constructed wells are commonly used to measure hydraulic head in all saturated systems, even in fine-grained sediments. Previous studies (Hvorslev 1951, Penman 1961) have shown that time lag in response to head changes between traditional wells and the surrounding fine-grained sediments can be a significant source of error. Time lag is caused by the time required for water to flow into or out of the well to reflect the appropriate change in head.

A low-volume piezometer was constructed to measure changes in hydraulic head without requiring a change in fluid volume within the piezometer by directly measuring pore pressure in …


The Benefits Of Interleaving Different Kinds Of Mathematics Practice Problems, Kelli M. Taylor Apr 2008

The Benefits Of Interleaving Different Kinds Of Mathematics Practice Problems, Kelli M. Taylor

USF Tampa Graduate Theses and Dissertations

In most mathematics textbooks, virtually all of the problems in each set of practice problems, or in each practice set, relate to the immediately preceding lesson - an arrangement described here as the standard format of practice. Alternatively, the problems within a shuffled practice set are drawn from numerous lessons. With the shuffled format, each practice set has two distinguishing features: within-session spacing, in which problems of the same kind appearing in a single practice set are separated by some period of time, and mixed practice, in which different types of problems are interleaved. Although previous studies …


Metallopeptides As Model Systems For The Study Of Cu(Ii)-Dependent Oxidation Chemistry, William Maung Tay Apr 2008

Metallopeptides As Model Systems For The Study Of Cu(Ii)-Dependent Oxidation Chemistry, William Maung Tay

USF Tampa Graduate Theses and Dissertations

Copper is one of the essential metal ions for aerobic organisms. Two well known functions of copper in the biological systems are electron transfer and molecular oxygen interaction. Thus, this metal can be found in haemocyanin, an oxygen carrier protein, and superoxide dismutase, an enzyme that involves in electron transfer. In addition, having a positive redox potential allows copper to be involved in redox chemistry. It is the redox properties of copper that are responsible for many important biochemical processes. Although the copper-containing oxidases have been well studied over the years, certain mechanistic details such as reaction intermediates remain to …


Cob Building: Movements And Moments Of Survival, Jeanine Marie Minge Apr 2008

Cob Building: Movements And Moments Of Survival, Jeanine Marie Minge

USF Tampa Graduate Theses and Dissertations

Cob, as an arts-based research process, creates movements and moments of survival. Survival is an ideological construction and an actual, local practice. Survival is also about desiring and fulfilling arts-based desires to work with the land through academic and material scavenging. Cob creates strategies for surviving, for working with our respective environments wisely. Cob building teaches people how to negotiate the natural economy and their relationships to labor and each other through an artistic and intimate practice. From a feminist poststructural lens, survival happens on the local level, between and with people. Cob building creates knowledge through creative, kinesthetic, and …

USF Tampa Graduate Theses and Dissertations

This study aimed to determine whether the rate of perceptual learning in a vernier discrimination task could be influenced by affective images. Forty-eight (30 Female, 18 Male) subjects were instructed to indicate the direction of an offset over 620 trials. Subjects were primed with either negative, positive or neutral photographs before making the discrimination on all test trials. Feedback regarding offset performance was provided on each trial. Despite initial pilot data indicating that subjects primed with negative, arousing images improved performance over those primed with either neutral or positive images, there was ultimately no reliable advantage for any of the …


The Effects Of Non-Surgical Interventions On Osteoarthritis-Like Changes In The Mouse Knee, Wendy K. Anemaet Mar 2008

The Effects Of Non-Surgical Interventions On Osteoarthritis-Like Changes In The Mouse Knee, Wendy K. Anemaet

USF Tampa Graduate Theses and Dissertations

Osteoarthritis (OA) is a debilitating condition affecting over 21 million persons in the United States. This number is expected to rise in the coming decades. Treatment approaches for OA focus on symptom modifying measures (i.e., pain relief) as disease modifying interventions do not currently exist. However, some of the interventions used to alleviate the symptoms of OA are also thought to have disease-modifying benefits. Two such non-surgical interventions for OA are intra-articular hyaluronan (HA) injections and physical exercise. In order to effectively study their effects in human OA, animal models that are amenable for studying intervention outcomes are needed.

The …


The Influence Of Apathy And Depression On Cognitive Functioning In Parkinson’S Disease, London C. Butterfield Mar 2008

The Influence Of Apathy And Depression On Cognitive Functioning In Parkinson’S Disease, London C. Butterfield

USF Tampa Graduate Theses and Dissertations

Depression and apathy are two of the most common psychiatric symptoms in Parkinson's disease (PD) with prevalence estimates at higher rates than in medical populations with similar levels of disability. Several studies have provided evidence to suggest that apathy and depression are independent clinical phenomena that may differentially affect cognition. Recent research suggests that apathy may account for cognitive deficits over and above that of depression, especially in the domain of executive functioning. However, few studies have examined the independent influence of depression and apathy on cognitive abilities in patients diagnosed with PD using sensitive measures of specific cognitive domains. …

Fashion Advertising, Men’S Magazines, And Sex In Advertising: A Critical-Interpretive Study, Jennifer Ford

USF Tampa Graduate Theses and Dissertations

This study examines sexualized portrayals of women in fashion advertising found in metro-sexual men's magazines as visual rhetoric. Historically, studies on sexual images of women in advertising have focused on content analyses of these images and how they affect women. This study asks how sexualized imagery of women functions rhetorically as part of a branding message designed to sell products. The exemplar advertisements were chosen specifically for their sexual imagery from an earlier study by the researcher on sexual images of women in fashion advertisements found in men's magazines.

The messages interpreted within the visuals of this study reveal a …


The Impact Of Computer Mediated Communication Systems Monitoring On Organizational Communications Content, Carolyn F. Holton Mar 2008

The Impact Of Computer Mediated Communication Systems Monitoring On Organizational Communications Content, Carolyn F. Holton

USF Tampa Graduate Theses and Dissertations

Employer monitoring of communications is prevalent and on the rise due in part to the Sarbanes-Oxley Act, the Health Insurance Privacy Protection Act, and other legislation in the U.S. and other countries. However, the critical effect of this new activity on what is communicated in companies has not been assessed. This dissertation examines the impacts of computer mediated communication systems monitoring on neutral, incriminating and exculpatory content, as well as the overall volume of communications issued on monitored and non-monitored computer mediated communication systems. Incriminating communication is cataloged in a hazard communications taxonomy for this investigation. A controlled laboratory experiment …

Recognition Memory For Emotional Words: An Event Related Potential Study, Catherine C. Balderston Mar 2008

Recognition Memory For Emotional Words: An Event Related Potential Study, Catherine C. Balderston

USF Tampa Graduate Theses and Dissertations

Evidence suggests that emotion affects memory often yielding enhanced recall and recognition of stimuli with emotional content. The nature of the relationship between emotion and memory for words has been particularly difficult to parse in part because of the stimulus characteristics. For example, emotional words tend to engender greater levels of physiological and psychological arousal, which have also been shown to enhance memory. Inter item relatedness has also been suggested as playing a part in the observed effects (i.e., emotional words belong to a closed semantic category compared to neutral words and are therefore easier to remember). While the enhancement …
