A Comparison Between First-Year Alternative Certified Teachers And First-Year Traditional Certified Teachers Based On Students' Academic Achievement: The Case Of A High-Need Urban Southeast District In Virginia, Abdou Maty Sene

Theses and Dissertations in Urban Studies

Debate about teacher supply and demand has been renewed in recent years by an increased concern about the reduced numbers of students entering teacher education programs and the resulting teacher shortages. Thus, American schools are experiencing teacher shortages, especially in low-income urban areas, because of increased school enrollment, teacher retirement, reduction of class size, teacher attrition, and turnover related to low salaries, job dissatisfaction, lack of administrative support and influence over decision-making. Recently, the increased interest in teacher quality has been the topic of debate for educational policy makers, and many researchers have focused on teacher certification.

The purpose of …

Computer Science Theses & Dissertations

With the growth in computing, storage and networking infrastructure, it is becoming increasingly feasible for multimedia professionals—such as graphic designers in commercial, manufacturing, scientific and entertainment areas—to work with 3D digital models of the objects with which they deal in their domain. Unfortunately most of these models exist in individual repositories, and are not accessible to geographically distributed professionals who are in need of them.

Building an efficient digital library system presents a number of challenges. In particular, the following issues need to be addressed: (1) What is the best way of representing 3D models in a digital library, so …

The Meaning Of Probability Judgments: An Essay On The Use And Misuse Of Behavioral Economics, Charles M. Yablon

Articles

In this essay, Professor Yablon challenges the assumption that behavioral heuristics-such as the availability heuristic -constitute "biases" that necessarily lead to errors in probability judgments. He notes that there are many different concepts of probability and, in many contexts, no agreed-upon method for determining the correctness of inconsistent probability judgments. Yet many legal academics and policymakers ignore these complex aspects of probability theory, assuming that statistical or frequentist probabilities are always to be preferred over subjective judgments of probability.

Professor Yablon argues that choosing between frequentist and subjective approaches to probability judgments in policymaking can only be done with great …

An Evaluative Framework For Assessing Information Management In Watershed Management: The Case Of The Grand River Conservation Authority (Ontario), Robert Scott Brown

Theses and Dissertations (Comprehensive)

Watershed management has been rapidly evolving over the last 50 years. The current focus has been adaptive and ecosystem-based approaches to watershed management, redefining roles, responsibilities, and relationships of watershed organizations. While entire management models need to be heavily scrutinized, the practices and policies surrounding information are fundamentally important. Information forms the understanding and knowledge for watershed decision-making. Watershed organizations need to be critical of the policies and practices affecting their collection, storage, processing, analysis, monitoring, and reporting of data and information. Among the Conservation Authorities, the GRCA has developed a proficiency at information management, doing it as well as …

Regional Planning And British Columbia's Agricultural Land Reserve: A Case Study Of Land Use, Development And Policy Impacts In The Central Okanagan Valley, Danielle H. Noble

Theses and Dissertations (Comprehensive)

In North America, farmland is commonly targeted as the site of urbanization, because it is often the most easy to develop. British Columbia has been no exception. But British Columbia is unique in North American planning because it has imposed a comprehensive agricultural land reserve (ALR), now over thirty years old, to respond to agricultural land loss. Such an instrument can have important implications for land-use planning and for planning practice. This research documents some of the impacts of the ALR on planning while focusing on the Central Okanagan Valley as a case study region. The lessons of the Okanagan …

The Dependence Of The Overall Drying Time And Product Quality Of A Lyophilization Process On The Relative Position Of Vials On A Tray With Tray Sides And Without Tray Sides For Different Heat Input Control Policies, Kian Hui Gan

Masters Theses

"The dynamic behavior of the primary and secondary drying stages of the lyophilization process were studied when (a) single vials located at different positions on the tray were individually being dried, and (b) the vials on the tray are arranged in clusters of square and hexagonal arrays and all the vials on the tray are simultaneously being dried. For both cases (a) and (b), fast drying times and relatively more uniform distributions of temperature and concentration of bound water at the end of the secondary drying stage are obtained by heat input control that runs the lyophilization process close to …

Articles

The aim of this paper is to investigate the relationship between Bmode and colour Doppler technical test methods with the clinical perception of Bmode and Doppler invivo test parameters. It was found that technical and clinical comparisons between the Bmode test parameters: lateral resolution versus clinical resolution; anechoic target detection versus clinical noise; and penetration depth versus clinically useful penetration depth, demonstrated moderate correlations, (r= 0.69, p

Validation Of A Sensitivity Performance Index Test Protocol And Evaluation Of Colour Doppler Sensitivity For A Range Of Ultrasound Scanners, Jacinta Browne, Amanda Watson, Peter Hoskins, Alex Elliott

Articles

The ability to detect flow is the most crucial aspect of an ultrasound (US) system because, if flow cannot be detected, no other aspect of performance matters. The objectives of this study were to validate a Doppler “sensitivity performance index,” a figure of merit, and to determine if it could be used to differentiate colour Doppler sensitivity performance in scanners of varying complexity. The sensitivity performance index was developed to give a combined measure of related aspects of sensitivity, such as the lowest detectable velocity, the vessel size and the penetration depth. The colour Doppler sensitivity was evaluated objectively as …

Objective Measurements Of Image Quality, Jacinta Browne, Amanda Watson, Nicholas Gibson, Nicholas Dudley, Alex Elliott

Articles

Tissue harmonic imaging (THI) and compound imaging have been reported clinically to improve contrast resolution, tissue differentiation and overall image quality. However, there have been limited studies to date to quantify objectively the improvements in image quality achieved with these new imaging techniques. The aim of this study was to quantify differences in image quality that exist between conventional B-mode imaging, harmonic imaging, compound imaging and harmonic compound imaging. An ATL HDI 5000 scanner with three probes (C5-2, L7-4 and L12-5) was tested with two different types of test object, the Gammex-RMI model 404 GS LE and the Gammex-RMI 403 …

High-Speed Electronic Speckle Pattern Interferometry, Carol Armstrong

Masters

Electronic Speckle Pattern Interferometry (ESPI) is used to measure surface displacements. Phase shifting can be used to obtain a fringe pattern which depicts the phase at every point in an image. Previous studies have used algorithms such as the 4-bucket algorithm to obtain phase maps of objects. After the object is displaced a second phase map is obtained in the same way and by correlation the phase difference due to the displacement can be determined. When the object is in rapid continuous motion these algorithms cannot be used. Towards this end a 5-frame algorithm was written, in which the calibrated …

Studies In Cardiac Defribrillation, Eamonn Mckenna

Masters

Cardiac disease resulting in cardiac arrest is one of the most common fatal diseases in the developed world. Defibrillation is the medical procedure used to correct the irregular cardiac rhythm (ventricular fibrillation (VF)) which is very often detected in patients suffering cardiac arrest. In the work reported in this thesis, two aspects of the defibrillation of patients in VF were examined. The first area of investigation concentrated on the use of multiple defibrillation electrodes to be used during closed chest (transthoracic) defibrillation. This study was carried out in a saline bath and centred on “focusing” electric fields from perimeter electrodes …

Restoring The Individual Plaintiff To Tort Law By Rejecting ‘Junk Logic’ About Specific Causation, Vern R. Walker

Hofstra Law Faculty Scholarship

Judges are removing the individual plaintiffs from many torts cases, and are instead conducting fact-finding about abstract statistical individuals. But the reasoning about specific causation in those cases is often fallacious. This Article critiques the error by analyzing direct inferences from causal generalizations about groups to probabilistic conclusions about causation in individuals. It identifies six distinct types of uncertainty in such inferences: measurement uncertainty, sampling uncertainty, modeling uncertainty, causal uncertainty, uncertainty about plaintiff representativeness, and uncertainty about assigning a probability to a specific plaintiff. These six uncertainties are logically necessary to this type of inference, and are not peculiar to …

Deconstructing The Tower Of London : Resolution, Alternatives And Executive Function, Hassina Carder-Gilbert

School of Psychology Theses

Although widely employed as an executive task, the performance demands of the Tower of London task (TOL) are not well understood. The aim of this Thesis is to determine what TOL measures and seven studies are included that illustrate its performance demands. Much of the work is experimental and TOL is explored via a novel verification paradigm in which participants make speeded judgements about whether a demonstrated move is optimal or suboptimal. The deconstruction of the task to the level of the individual move indicated that the number of moves until a disk was placed in its goal position (resolution) …

Integrating Perception, Language And Problem Solving In A Cognitive Agent For A Mobile Robot., Deryle W. Lonsdale, D. Paul Benjamin, Damian M. Lyons

Faculty Publications

We are implementing a unified cognitive architecture for a mobile robot. Our goal is to endow a robot agent with the full range of cognitive abilities, including perception, use of natural language, learning and the ability to solve complex problems. The perspective of this work is that an architecture based on a unified theory of robot cognition has the best chance of attaining human-level performance.

This agent architecture is an integration of three theories: a theory of cognition embodied in the Soar system, the RS formal model of sensorimotor activity and an algebraic theory of decomposition and reformulation.

These three …
