A Model Of Responses To Race-Based And Gender-Based Stereotype Threat In Computer Science, Lara Tedrow

Psychology Theses & Dissertations

The perception of stereotype threat among computer science students was examined at two universities. A model of stereotype threat was developed and tested among students enrolled in three undergraduate computer science courses at two universities. The goal of this model was to provide an understanding of the underlying mechanisms through which stereotype threat works.

The study tested relationships among the following variables: race-based stereotype threat, gender-based stereotype threat, goal orientation, CS self-efficacy, active coping, behavioral disengagement, effort, and performance. Structural equation modeling was used to test the measurement model and a series of nested structural models. Findings supported the proposed …

Biogenic Tracers Through The Holocene On The Alaskan Shelf, Carie A. Curry

OES Theses and Dissertations

Dramatic environmental changes in the Arctic Ocean have been observed for the last two decades including changing the amount of sea ice thickness and extent, and increased river discharge. In order to put these and other current day observations into historical context and perhaps reveal mechanisms controlling them, a suite of paleo-proxies were used to analyze two high resolution cores collected on the 2005 HOTRAX expedition. The goals of this research were: (1) develop an analytical method for determining biogenic calcite, (2) identify the major sources of biogenic matter into the system over the Holocene, and (3) assemble the history …

Comparative Study Of Forward And Diffusely Scattered Light In A Coherently Prepared Ultracold Rubidium Gas, Rocio Gisel Olave Gonzalez

Physics Theses & Dissertations

A comparison between forward and diffusely scattered light propagating in a coherently prepared ultracold ⁸⁷Rb atomic vapor is presented. This research is part of the ongoing effort to characterize the processes, such as diffusion, that contribute to coherence loss in atomic media under conditions of electromagnetically induced transparency, for applications in realistic systems. Toward this end, a magneto optical trap (MOT) of ⁸⁷Rb has been built, and the atomic vapor sample characterized in terms of atomic density, shape and size, temperature, and optical depth. Next, two co-propagating beams were sent through the sample, to establish an electromagnetically induced …

Transformation Paradox: A Framework For The Analysis Of Politics In Enterprise Transformations, Cindy S. Miller

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research is to develop a theoretical framework for the analysis of politics in enterprise transformations using a dialectical analysis approach (Hegel, 1989; Heraclitus, 1979; Pinkard, 1988; Skinner, 1978a, 1978b) and conduct an evaluation of the framework validity. The framework is constructed using a dialectical analysis of concepts stemming from the work of Alford and Friedland (1992) and considers four theoretical perspectives: autocratic, bureaucratic, pluralistic, and cognitive. The framework is then validated by means of qualitative metrics and adherence to critical ideology.

This research addresses the problem that there is no holistic theoretical framework for the analysis …

A Protocol For Occupational Therapy Involvement In The Response To Intervention Model, Nicole Bolinger

Occupational Therapy Capstones

In order to provide effective occupational therapy services to children within the school-based practice setting, it is important to be knowledgeable regarding the current theories and educational models which drive the educational system. Also, it is imperative that school-based occupational therapy practitioners understand the educational models and how they may impact the way occupational therapists deliver services. Chandler (2007) states, "an initiative is gathering momentum that has the potential to significantly change the way occupational therapists practice in the public school" (p. 7). Occupational therapy may have an opportunity to expand their services through a model called Response to Intervention. …

Decision Aids For Addressing The Validity-Adverse Impact Trade-Off, Paul R. Sackett, Wilfried De Corte, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Typically, adverse impact (AI) is an after-the-fact analysis: Once predictor scores for a pool of applicants are available, AI is evaluated. Sometimes the analysis is made in real time, as predictor scores are obtained on a set of applicants, and AI calculations are done on a “what if” basis as input to decisions about features such as where to set a cutoff score. The focus of this chapter, however, is on attempts to estimate in advance the likely impact of a given selection system. Here, estimates are made based on available information about the features such as the expected magnitude …

Chaos And Uncertainty, M. Thulasidas

Research Collection School Of Computing and Information Systems

The end of 2008 in the finance industry can be summarized in two words – chaos and uncertainty. The subprime crisis, where everybody lost; the dizzying commodity price movements; the pink slip syndrome; the spectacular bank busts; and the gargantuan bail-outs all vouch for it.

(2009) Caring For The “Self As One Among Others”, Laurance J. Splitter

Collected Papers of Laurance J. Splitter

n this paper, I explore some underpinnings of the community of inquiry (CoI), viewed as the primary mode of classroom organization in Philosophy for Children but also as a pedagogic, personal and inter-personal framework for teaching and learning in any subject area. I will argue that the CoI provides a model of both personal and intellectual development which exemplifies how classroom teaching and learning may be seen both as forms of care and of self-care.

Effects Of Quantum Mechanics On The Deflagration Threshold In The Molecular Magnet Mn12 Acetate, F Macià, J M. Hernandez, J Tejada, S Datta, S Hill, Christos Lampropoulos, G Christou

Chemistry Faculty Research and Scholarship

We report experimental studies of the stability of a Mn₁₂-Ac crystal against magnetic avalanches as a function of the magnitude and direction of the magnetic field, as well as a function of temperature. Strong evidence for quantum effects associated with this phenomenon is seen in the (H_z,H_x) metastability diagram. The data provide further support to the theory of magnetic deflagration.

Crystal Lattice Desolvation Effects On The Magnetic Quantum Tunneling Of Single-Molecule Magnets, G Redler, Christos Lampropoulos, S Datta, C Koo, T C. Stamatatos, N E. Chakov, G Christou, S Hill

Chemistry Faculty Research and Scholarship

High-frequency electron paramagnetic resonance (HFEPR) and alternating current (ac) susceptibility measurements are reported for a new high-symmetry Mn₁₂ complex, [Mn₁₂O₁₂(O₂CCH₃)₁₆(CH₃OH)₄]⋅CH₃OH. The results are compared to those of other high-symmetry spin S=10 Mn₁₂ single-molecule magnets (SMMs), including the original acetate, [Mn₁₂(O₂CCH₃)₁₆(H₂O)₄]⋅2CH₃CO₂H⋅4H₂O, and the [Mn₁₂O₁₂(O₂CCH₂Br)₁₆(H₂O)₄]⋅4CH₂Cl₂ and [Mn₁₂O …

Alignment Of Magnetic Anisotropy Axes In Crystals Of Mn12 Acetate And Mn12-Tbuac Molecular Nanomagnets: Angle-Dependent Ac Susceptibility Study, E Burzurí, Ch Carbonera, F Luis, D Ruiz-Molina, Christos Lampropoulos, G Christou

Chemistry Faculty Research and Scholarship

We report the results of angular-dependent ac susceptibility experiments performed on two derivatives of Mn₁₂ single-molecular magnets: the well-known Mn₁₂ acetate, which contains disordered acetic acid molecules in interstitial sites of the crystal structure and Mn₁₂-tBuAc, for which solvent molecules are very well ordered in the structure. Our results show (a) that the angular variation is very similar in the two compounds investigated and compatible with a maximum misalignment of the anisotropy axes of less than 3° and (b) that the tunneling rate is faster for the better ordered Mn₁₂-tBuAc compound. These experiments question …

Management And Social Indicators Of Soil Carbon Storage In A Residential Ecosystem, Midlothian, Va, Christopher M. Gough, Eliza A. Fritz

Virginia Journal of Science

Soil carbon storage- defined here as carbon mass per unit ground area- is an important ecosystem service, sequestering carbon that might otherwise exist in atmospheric CO₂ . Significant attention has focused on the effects that humans have on carbon cycling, but little is known about how human behaviors and attitudes relate to lawn carbon storage. The objectives of this study were to conduct household surveys in concert with soil carbon sampling in a 10-year-old exurban neighborhood near Richmond, Virginia to quantify differences in soil carbon storage between residential lawns and mixed pine-hardwood forest fragments, and to determine how lawn …

Decentralized Or Centralized Production : Impacts To The Environment, Industry, And The Economy, Abigail R. Clarke-Sather

Dissertations, Master's Theses and Master's Reports - Open

Since product take-back is mandated in Europe, and has effects for producers worldwide including the U.S., designing efficient forward and reverse supply chain networks is becoming essential for business viability. Centralizing production facilities may reduce costs but perhaps not environmental impacts. Decentralizing a supply chain may reduce transportation environmental impacts but increase capital costs. Facility location strategies of centralization or decentralization are tested for companies with supply chains that both take back and manufacture products.

Decentralized and centralized production systems have different effects on the environment, industry and the economy. Decentralized production systems cluster suppliers within the geographical market region …

Thinking Like A Research Expert: Schemata For Teaching Complex Problem-Solving Skills, Paul D. Callister

Faculty Works

The difference between expert and novice problem solvers is that experts have organized their thinking into schemata or mental constructs to both see and solve problems. This article demonstrates why schemata are important, arguing that they need to be made explicit in the classroom. It illustrates the use of schemata to understand and categorize complex research problems, map the terrain of legal research resources, match appropriate resources to types of problems, and work through the legal research process. The article concludes by calling upon librarians and research instructors to produce additional schemata and develop a common hierarchical taxonomy of skills, …

The Effectiveness Of Teaching Math Using Manipulatives In The Fourth Grade At Southwest Laurens Elementary, Denise D. Taylor

The Corinthian

I have taught math at Southwest Laurens Elementary for the past twenty years, my first twelve years as a second, third, fourth, fifth, and sixth grade Title I teacher and my last eight years as a self-contained regular education fourth grade teacher. For all twenty years I have taught at least one math class. One concern I have often had with the math curriculum at my school was the exclusion of many math manipulatives either because of lack of funding or because of the required time for preparation of lessons and instruction when including manipulatives. In this research project, I …

This report describes the 2009 greenhouse gas emissions inventory of the University of North Florida. Such inventories are becoming more important as society approaches restrictions on carbon dioxide emissions due to their effects on global warming. Greenhouse gas emissions inventories have been conducted on hundreds of campuses in the United States, as well as thousands of other organizations worldwide, including U.S. private corporations. An inventory like this generally forms the initial baseline for a campus climate action plan. Climate action plans have also been created by hundreds of universities and other entities. Following the release of this report, a UNF …

Habitat Selection By Anolis Carolinensis (Green Anole) In Open Pine Forests In Eastern Texas, Richard R. Schaefer, Robert R. Fleet, D. Craig Rudolph, Nancy E. Koerth

Faculty Publications

We initiated a mark-recapture study to determine the effects of shrub density on Anolis carolinensis (Green Anole) populations. Green Anole perch site, shrub species, and shrub volume preferences were also examined. We established two study plots of different shrub densities in open pine forests on the Angelina National Forest in eastern Texas. In late spring, the Green Anole population at the higher shrub-density plot was estimated to be 16 times greater than the population at the lower shrub-density plot. Green Anoles most commonly perched on live shrubs, but exhibited very little preference or avoidance of any particular species of live …

Micro-Fluidic Based Numerical Simulations And Experiments On Streaming Induced By Oscillatory Flows, Chang Liu

Open Access Dissertations

Streaming effect induced in oscillatory viscous flows has been studied for more than a century. An intensive literature review is made first in this study, and the major applications related to streaming are discussed. In this study, the streaming problem is the fluid drifting phenomenon that occurs in a volume-cycled (tidal volume is fixed during oscillation) oscillatory flow in a channel with specified geometries (bifurcation networks and tapered shapes) Different from all the previous studies, this study extends the streaming effect down to the micro scale. Numerical approaches were carried out using Fluent (ANSYS, Inc., Canonsberg, PA), a commercial computational …

Regulation Of Survivin Gene Expression In The Human Endometrium And Endometrial Cancer, Nancy H. Nabilsi

Dissertations and Theses (Open Access)

In the United States, endometrial cancer is the leading cancer of the female reproductive tract. There are 40,100 new cases and 7,470 deaths from endometrial cancer estimated for 2008 (47). The average five year survival rate for endometrial cancer is 84% however, this figure is substantially lower in patients diagnosed with late stage, advanced disease and much higher for patients diagnosed in early stage disease (47). Endometrial cancer (EC) has been associated with several risk factors including obesity, diabetes, hypertension, previously documented occurrence of hereditary non-polyposis colorectal cancer (HNPCC), and heightened exposure to estrogen (25). As of yet, there has …
