A Survey Of Progressive And Affirmative Employee Discipline Systems In Florida's Hospitals, Mark Johnson Jan 2005

A Survey Of Progressive And Affirmative Employee Discipline Systems In Florida's Hospitals, Mark Johnson

Electronic Theses and Dissertations

Conflict between managers and employees is inevitable in any organization, whether public or private. Often, the source of the conflict is employee non-compliance. Managers are responsible for disciplining those employees whose performance or conduct is sub-standard or inappropriate. Therefore, the ability to effectively address employee non-compliance is an essential skill for all managers. Most employee discipline systems fall into one of three categories: traditional, progressive, and affirmative. Traditional systems were prevalent in the late-nineteenth and early twentieth centuries. An autocratic, demanding manager would mete out punishment to non-compliant employees both as an action against the employee and as a warning …

Selenotrisulfide Derivative Of Alpha-Lipoic Acid: Evaluation In A Cell Culture Model For Potential Use As A Topical Antioxidant, Melenie Lee Alonis

Electronic Theses and Dissertations

Selenium is a required micronutrient in mammalian cells. It is incorporated in the form of selenocysteine into selenoenzymes such as glutathione peroxidase and thioredoxin reductase, and is absolutely required for activity. Thioredoxin reductase is necessary for reduction of oxidized thioredoxin and therefore plays a major role in maintaining the redox status of the cell. Glutathione peroxidase is responsible for reducing peroxides into their corresponding alcohols and water. Together, these selenoenzymes constitute a significant part of the cell's arsenal to defend itself against oxidative stress. Exogenous sources of oxidative stress, such as UV radiation, are capable of generating reactive oxygen species …

Life Event Perception: A Structural Equation Modeling Approach To The Antecedents Of The Life Stress Response, Christopher Aaron Myers

Electronic Theses and Dissertations

It has been often argued that life events have an impact on our physical and psychological well-being. In general, research supports this connection between life events and general health, though some argue that simply experiencing life events has a measurable and predictable impact our health, while others contend that this effect is mediated by the appraisal process. Further, research has identified a number of different factors (hypothetically stratified into pre-existing beliefs, external resources and demands, and behavioral activation and coping strategies) that may influence appraisal and general health. The current study attempts to integrate these findings by testing structural models …

Synthesis And Characterization Of Nanocrystalline Hydroxyapatite Powder; And The Effects Of Oxide-Based Sintering Additives On Tricalcium Phosphate, Himesh A. Bhatt

Electronic Theses and Dissertations

Calcium phosphate (CP) materials have been used extensively for bone replacement and augmentation due to their similarity to the mineral component of bone. In addition to being non-toxic, they are biocompatible, not recognized as foreign materials in vivo, and most importantly, exhibit osteoconductive behavior, being able to help in bone formation during healing. CPs form an intimate physicochemical bond with the host tissue, termed osseointegration. However the main limitation of calcium phosphates is their inherent brittle nature and poor mechanical performance under complex stress states. As a result, these materials have been used clinically only in non-load-bearing applications, primarily as …

Nondestructive Evaluation Of Thermal Barrier Coatings With Thermal Wave Imaging And Photostimulated Luminescence Spectroscopy, Barbara Franke Jan 2005

Nondestructive Evaluation Of Thermal Barrier Coatings With Thermal Wave Imaging And Photostimulated Luminescence Spectroscopy, Barbara Franke

Electronic Theses and Dissertations

Gas Turbine manufacturers strive for increased operating temperatures of gas turbine engines to improve efficiency and performance. One method of increasing the temperature beyond material limits is by applying thermal barrier coatings (TBCs) to hot section components. TBCs provide a thermal gradient between the hot gases and metallic substrate, and allow an increase in turbine inlet temperatures of 100-150ºC. However, spallation of TBCs can cause catastrophic failure of turbine engines by incipient melting of the substrate. To prevent such an occurrence, non-destructive evaluation (NDE) techniques are critical for quality control, health monitoring, and life assessment of TBCs. Two techniques in …
