Magnetic Nanosensors For Multiplexed Bacterial Pathogenesis Identification, Charalambos Kaittanis Jan 2010

Magnetic Nanosensors For Multiplexed Bacterial Pathogenesis Identification, Charalambos Kaittanis

Electronic Theses and Dissertations

Developing diagnostic modalities that utilize nanomaterials and miniaturized detectors can have an impact in point-of-care diagnostics. Diagnostic systems that (i) are sensitive, robust, and portable, (ii) allow detection in clinical samples, (iii) require minimal sample preparation yielding results quickly, and (iv) can simultaneously quantify multiple targets, would have a great potential in biomedical research and public healthcare. Bacterial infections still cause pathogenesis throughout the world (Chapter I). The emergence of multi-drug resistant strains, the potential appearance of bacterial pandemics, the increased occurrence of bacterial nosocomial infections, the wide-scale food poisoning incidents and the use of bacteria in biowarfare highlight the …

An Assessment Of Sea Turtle Nesting Behavior In Relation To Hurricane- And Restoration-Induced Beach Morphodynamics, Tonya Michele Long Jan 2010

An Assessment Of Sea Turtle Nesting Behavior In Relation To Hurricane- And Restoration-Induced Beach Morphodynamics, Tonya Michele Long

Electronic Theses and Dissertations

Coastal habitats are highly dynamic and vulnerable to landscape-level disturbances such as storms and restoration projects. Along the east coast of Florida these areas are particularly valuable as they provide significant nesting habitat for two sea turtle species, the threatened loggerhead (Caretta caretta) and the endangered green turtle (Chelonia mydas). This coast was heavily impacted by three major hurricanes in 2004 and in some areas by large restoration projects in 2005. Recent remote sensing methods allow for broad evaluation of the shoreline and thus the ability to assess sea turtle nesting habitat at a landscape scale. I collected nesting data …

Assessing The Psychometric Properties Of The Counseling Competencies Scale A Measure Of Counseling Skills, Dispositions, And Behaviors, Jacqueline Melissa Swank Jan 2010

Assessing The Psychometric Properties Of The Counseling Competencies Scale A Measure Of Counseling Skills, Dispositions, And Behaviors, Jacqueline Melissa Swank

Electronic Theses and Dissertations

Ethical and competent professional counselors are needed to provide quality counseling services to the public. Counselor educators and supervisors have the responsibility of training competent counselors. Furthermore, counselors and counselors-in-training have the responsibility of continually assessing their own development and implementing measures to increase their competency. Assessment instruments have sought to measure counseling competencies through evaluating counseling skills. However, a paucity of research exists that examines counseling competencies in a comprehensive manner using a psychometrically sound approach. Therefore, a need exists for a psychometrically sound assessment instrument that measures the construct of counseling competencies in a holistic manner. Thus, the …

Electroconvulsive Shock Ameliorates Disease Processes And Extends Survival In Huntington Mutant Mice, Akanksha Baharani Jan 2010

Electroconvulsive Shock Ameliorates Disease Processes And Extends Survival In Huntington Mutant Mice, Akanksha Baharani

Electronic Theses and Dissertations

Huntington's disease (HD) is a devastating autosomal dominantly inherited neurological disorder caused by an abnormal expansion of CAG trinucleotide repeats in the gene coding for the Nterminal region of the huntingtin (Htt) protein, which leads to the formation of a polyglutamine stretch. The greater the CAG repeats, the earlier the onset of the disease. The polyglutamine stretch destabilizes the Htt protein leading to misfolding, abnormal processing, aggregation, and inclusion formation. Mutant Htt protein is believed to damage and kill neurons in the striatum by a mechanism involving increased oxidative and metabolic stress, and impaired adaptive cellular stress responses. A large …

Job Satisfaction And Values Of Counselors In Private Practice And Agency Settings, Laura Cunningham

Electronic Theses and Dissertations

Counselors can work at a variety of locations (Vacc & Loesch, 2000). Yet very little is known about each setting (King, 2007) and what type of counselors would have an optimum fit. Burnout is a pervasive issue in counseling (Lawson, 2007) and providing good-fit information could lessen turnover and burnout from the counseling field. The primary purpose of this study included investigating the differences between job satisfaction and value priorities of counselors in private practice and agency settings. The overarching theoretical framework included Frank Parsons‘ counselors, with seventy-two agency counselors and sixty-three private practitioners. Counselors completed two assessments and a …

Acetazolamide-Induced Decrease Of Apical Fluid Flow In Choroid Plexus Is Independent Of The Concomitant Changes In Aquaporin-1 Expression, Pouya Alexander Ameli Jan 2010

Acetazolamide-Induced Decrease Of Apical Fluid Flow In Choroid Plexus Is Independent Of The Concomitant Changes In Aquaporin-1 Expression, Pouya Alexander Ameli

Electronic Theses and Dissertations

Acetazolamide (AZA), the only drug approved for treatment of hydrocephalus, is effective in only 25-30% of patients while its effect on fluid flow in the choroid plexus (CP) is unknown. The drug reversibly inhibits Aquaporin 4 (AQP4), the most highly expressed „water pore‟ in the brain, and it is postulated that it reduces cerebrospinal fluid (CSF) production by modulating AQP1 (mostly found in the apical membrane of the CP). In this study, we sought to elucidate the effect of AZA on AQP1 and fluid flow in CP. Primary CP culture from p10 Sprague-Dawley rats and TRCSF-B cell line were grown …

Clinical Practice Guidelines For Emerging Ultrasound Applications Drafting For Validity And Usability, Kathi Keaton Borok Jan 2010

Clinical Practice Guidelines For Emerging Ultrasound Applications Drafting For Validity And Usability, Kathi Keaton Borok

Electronic Theses and Dissertations

Clinical practice guidelines (CPGs) are viewed by many people with interests in health care as valuable tools for reducing practice variations that undermine patient outcomes and increase medical costs. However, guidelines themselves vary in quality. Assessment tools generally base quality measures on strength of guidelines' evidence base, but particularly for newly emerging applications of ultrasound, standards for measuring guideline quality are controversial. The validity of a guideline is considered likely when strong research-based evidence supports its recommendations, but for newer medical procedures such as emerging ultrasound applications, available evidence is sparse. Existing assessment tools must be modified if they are …

Estimating Diet And Food Selectivity Of The Lower Keys Marsh Rabbit Using Stable Isotope Analysis, Matthew James Gordon Jan 2010

Estimating Diet And Food Selectivity Of The Lower Keys Marsh Rabbit Using Stable Isotope Analysis, Matthew James Gordon

Electronic Theses and Dissertations

Understanding the effect of food abundance on feeding behavior can benefit conservation efforts in many ways, such as to determine whether impacted environments need food supplementation, whether different locations of threatened species contain different food abundances, or whether reintroduction sites are missing key components of a species’ diet. I studied the relationship between feeding behavior and food abundance in the Lower Keys marsh rabbit (Sylvilagus palustris hefneri), an endangered subspecies endemic to the lower Florida Keys. Specifically, my study set out to measure the relative abundance of the primary plants within the natural habitat of the Lower Keys marsh rabbit …

Evaluation Of A Simulation-Enhanced Obstetric Clinical Experience On Learning Outcomes For Knowledge, Self-Efficacy, And Transfer, Mary Elizabeth Guimond Jan 2010

Evaluation Of A Simulation-Enhanced Obstetric Clinical Experience On Learning Outcomes For Knowledge, Self-Efficacy, And Transfer, Mary Elizabeth Guimond

Electronic Theses and Dissertations

Simulation using computerized patient mannequins may be a useful mechanism to teach safe and effective nursing care, thus improving the quality of education for nurses. As nursing program enrollments grow, clinical placement is becoming more difficult and may not offer consistent learning opportunities that reinforce safe and effective nursing practice. This study applied Ford, Smith, Weissbein, Gully, and Salas’ (1998) model of learning transfer as the theoretical framework to design a simulated obstetric clinical learning experience to augment the current clinical practice model, an approach that may lead to an improved educational experience. The purpose of this study was to …

Social Comparison, Self-Objectification, And Objectification Of Others Investigating The Vicious Cycle That Leads To Body Dissatisfaction And Disordered Eating, Danielle M. Lindner Jan 2010

Social Comparison, Self-Objectification, And Objectification Of Others Investigating The Vicious Cycle That Leads To Body Dissatisfaction And Disordered Eating, Danielle M. Lindner

Electronic Theses and Dissertations

The purpose of this study was to test a new theoretical model that integrates self-objectification, objectification of others, and social comparison as contributors to the development and maintenance of body image disturbance and disordered eating behavior. Within the new theoretical model, self-objectification, objectification of others, and social comparison are conceptualized as a self-perpetuating cycle, rather than as processes that occur independently of one another. Four hundred fifty-nine female college students between the ages of 18 and 32 completed measures of self-objectification, objectification of others, social comparison, body shame, body dissatisfaction, and eating disorder symptomatology. Structural equation modeling with nested model …

Dialectical Tensions Between Glocalization And Grobalization For Wal-Mart In The United States, Laura Lord Jan 2010

Dialectical Tensions Between Glocalization And Grobalization For Wal-Mart In The United States, Laura Lord

Electronic Theses and Dissertations

This qualitative analysis examines Wal-Mart managers‟ perspectives of the strategies that the U.S. corporation has implemented in order to increase its sales and profits at more than 4,000 stores in local U.S. communities. Two theoretical paradigms are specifically used: glocalization and grobalization. The former refers to cultural adaptation; the latter means standardization. The ultimate goal of the researcher is to identify the dialectical tensions between those two current forms of globalization. In-depth, face-to-face, qualitative interviewing of ten Wal-Mart managers in Central Florida allowed the researcher to actually comprehend managers‟ perspectives, gather fresh data, and construct a final product to enlighten …

Transplantation Of Ips Cells Reduces Apoptosis And Fibrosis And Improves Cardiac Function In Streptozotocin-Induced Diabetic Rats, Sarah Elizabeth Neel

Electronic Theses and Dissertations

Background: Streptozotocin (STZ) induced diabetes leads to various complications including cardiomyopathy. Recent data suggests transplanted bone marrow stem cells improve cardiac function in diabetic cardiomyopathy. However, whether modified ES, iPS cells, or factors released from these cells can inhibit apoptosis and fibrosis remains completely unknown. The present study was designed to determine the effects of transplanted ES cells overexpressing pancreatic transcription factor 1 a (Ptf1a), a propancreatic endodermal transcription factor, iPS cells, or their respective conditioned media (CM) on diabetic cardiomyopathy. Methods: Experimental diabetes was induced in male Sprague Dawley rats (8-10 weeks old) by intraperitoneal STZ injections (65 mg/kg …

A Model Of Flow And Play In Game-Based Learning The Impact Of Game Characteristics, Player Traits, And Player States, Davin Pavlas Jan 2010

A Model Of Flow And Play In Game-Based Learning The Impact Of Game Characteristics, Player Traits, And Player States, Davin Pavlas

Electronic Theses and Dissertations

In this dissertation, the relationship between flow state, serious games, and learning was examined. Serious games, which are games that convey something other than enjoyment (e.g., learning), are increasingly popular platforms for research, training, and advertisement. The elements that make serious games useful to researchers, trainers, and practitioners are closely linked to those that make up the positive psychology construct of flow state. Flow state describes an optimum experience that is encountered when a variety of factors are met, and is characterized by high focus, engagement, motivation, and immersion. While flow state is often discussed in the serious games literature, …

The Search For Theatre For Social Change, Britney Cooper Jan 2010

The Search For Theatre For Social Change, Britney Cooper

Electronic Theses and Dissertations

Throughout history people have sought to prompt social change through theatrical experiences. The theatre has moved the masses in ways that have frightened governments and religious establishments into closing down theatres and banning theatrical material. History proves that theatre which causes change exists and works, but it also proves there is no one definition or formula for this type of theatre. Depending on the culture, time period, issue, resources and people involved Theatre for Social Change takes a variety of forms. However, theatre affecting change does tend to maintain two common threads: the creation of a new work and the …

The Role Of The Feral Pig (Sus Scrofa) As A Disturbance Agent And Seed Disperser In Central Florida's Natural Lands, Camille Rose Brescacin Jan 2010

The Role Of The Feral Pig (Sus Scrofa) As A Disturbance Agent And Seed Disperser In Central Florida's Natural Lands, Camille Rose Brescacin

Electronic Theses and Dissertations

Feral pigs (Sus scrofa) are considered to be among the world’s worst invasive species due to their successful invasion and ecological and economic impact to native and agricultural plants and animals around the world. Feral pigs are significant disturbance agents that destroy plant communities, change soil characteristics, alter nutrient cycling, and create open sites for colonization of both native and non-native plant species through their foraging behavior called rooting. In contrast to native animal disturbances, rooting is a striking feature in the landscape that varies in space, seasonal timing, frequency (number of times rooted), and intensity (depth of rooting). During …

A Self-Organizing Hybrid Sensor System With Distributed Data Fusion For Intruder Tracking And Surveillance, Ravishankar Palaniappan Jan 2010

A Self-Organizing Hybrid Sensor System With Distributed Data Fusion For Intruder Tracking And Surveillance, Ravishankar Palaniappan

Electronic Theses and Dissertations

A wireless sensor network is a network of distributed nodes each equipped with its own sensors, computational resources and transceivers. These sensors are designed to be able to sense specific phenomenon over a large geographic area and communicate this information to the user. Most sensor networks are designed to be stand-alone systems that can operate without user intervention for long periods of time. While the use of wireless sensor networks have been demonstrated in various military and commercial applications, their full potential has not been realized primarily due to the lack of efficient methods to self organize and cover the …

An Empirical Investigation Into Organizational Learning In Hotel Organization, Umut Avci, Izzet Kilinc, Fevzi Okumus

Rosen Faculty Scholarship and Creative Works

This study aimed to investigate the relationship among individual learning, team learning and organizational learning. Data was collected from 799 employees, who worked in four and five star hotels operated in Mugla, Turkey. The study findings indicate that there is a meaningful relationship among individual learning, team learning and organizational learning. In particular, team learning appears to explain organizational learning more than individual learning. Based on the study findings, it can be recommended that in order to facilitate organizational learning, hotel organizations should critically analyze and utilize the factors that facilitate team learning.

A December To Remember, Richard C. Crepeau Dec 2009

A December To Remember, Richard C. Crepeau

On Sport and Society

It has been a December to remember. As the month comes to a close with a remarkable flurry of headline sports stories, its clear that this one month was not only one for the memory bank, but that it may have been the most fitting way to end a year that has certified the decade as the Naughty Naughties. What seemed like an awkward tag at the beginning of the new century has become a most appropriate signature phrase as this decade comes to its ignominious close.
