An Investigation Of The Dayton Regional Stem School Public-Private Partnerships, Kimberly S. Poole

CCE Theses and Dissertations

This dissertation study documents in-depth the exploration of the Public Private Partnerships (PPPs) between the Dayton Regional STEM School (DRSS) and their industry partners as well as the establishment of a framework for evaluating and assessing PPPs. The public-private partnership agreements were studied in order to answer the over-arching research question: How is an effective public-private partnership established, assessed, and evaluated in education? A descriptive case study methodology was used to study DRSS' public-private partnership agreements to determine if goals and objectives were established and whether or not the partnerships met those goals and objectives. This case study also included …

Predicting High-Stakes Tests Of Math Achievement Using A Group-Administered Rti Instrument: Validating Skills Measured By The Monitoring Instructional Responsiveness: Math, Jeremy Thomas Coles

Doctoral Dissertations

Three universal screeners and nine progress monitoring probes from the Monitoring Instructional Responsiveness: Math (MIR:M), a silent, group-administered math assessment designed for implementation with an RTI Model, were administered to 223 fifth-grade students. The growth parameters of the overall MIR:M composite and two global composites (math calculation and math reasoning) identified significant variation in student growth, within significant linear and quadratic trajectories. However, there were significant differences in the nature of the growth trajectories that have applied educational implications. In addition, growth parameters across the three composites provided significant predictive potential when using the Tennessee Comprehensive Assessment Program (TCAP) Achievement …

Characterization Of Waste Anesthetic Gas Exposures To Veterinary Workers In The Tampa Bay Area, Kyle Vogel

USF Tampa Graduate Theses and Dissertations

Veterinarians routinely conduct surgical operations on animals while veterinary technicians administer anesthetic gas to sedate the animal prior to an operation. One commonly used anesthetic agent in veterinary clinics is isoflurane. Veterinary workers have the potential to be exposed to this gas during surgical operations. The Occupational Safety and Health Administration (OSHA) does not have a specific Permissible Exposure Limit (PEL) for isoflurane, however The National Institutes for Health (NIH) does advise that workers should not be exposed to isoflurane in concentrations exceeding 2 parts per million (ppm) for an 8 hour Time Weighted Average (TWA).

Animal clinics vary in …

Assessing College Students' Understanding Of Acid Base Chemistry Concepts, Yanjun Wan

All Dissertations

Typically most college curricula include three acid base models: Arrhenius', Bronsted-Lowry's, and Lewis'. Although Lewis' acid base model is generally thought to be the most sophisticated among these three models, and can be further applied in reaction mechanisms, most general chemistry curricula either do not include Lewis' acid base model, or quickly mention it at the end of the acid base chapter, because of the concern that Lewis' model may confuse general chemistry students (Shaffer 2006). While such a disconnection in curriculum might put students to disadvantage as they try to construct solid and coherent acid base mental models, there …

An Information Security Control Assessment Methodology For Organizations, Angel Rafael Otero

CCE Theses and Dissertations

In an era where use and dependence of information systems is significantly high, the threat of incidents related to information security that could jeopardize the information held by organizations is more and more serious. Alarming facts within the literature point to inadequacies in information security practices, particularly the evaluation of information security controls in organizations. Research efforts have resulted in various methodologies developed to deal with the information security controls assessment problem. A closer look at these traditional methodologies highlights various weaknesses that can prevent an effective information security controls assessment in organizations. This dissertation develops a methodology that addresses …

Risk Assessment Of Waterborne Cryptosporidium, Victoria Norma Ochoa

Open Access Theses & Dissertations

In an effort to update the risk assessment of waterborne Cryptosporidium an additional and more complete human dose-response dataset of the parasite was used to calculate the risk of infection. The complete data studied contains larger human outcomes than the initial prior risk assessment evaluated by Haas et. al. in 1999. Quantitative analysis of the complete dose-response indicates that it no longer follows the Exponential Model used to estimate the risk for the initial data. The complete dataset appears to provide a better fit with the Beta-Poisson Model and even a dose independent constant risk model, which shows a considerable …

Refining Aquatic Macroinvertebrate Community Metrics For The Assessment Of Headwater Streams In New York State, Brian T. Duffy

Legacy Theses & Dissertations (2009 - 2024)

The River Continuum Concept describes the structural and functional shift that occurs from sensitive headwater streams to the lowest reaches of large, non-wadeable rivers. New York State (NYS) maintains a long-established biological monitoring program using macroinvertebrate community assemblages for water quality assessment. However, headwater streams are rarely assessed, and no reference models are available, except those calibrated for lower-continuum wadeable streams and rivers. Current patterns of rural landuse change emphasize the need for more accurate assessment of previously neglected headwaters, in order to set natural reference standards for more accurate assessments of water quality. Ecoregion, drainage area (DA), elevation (elev.), …
