Primary teachers in the United States accept responsibility for teaching children how to read, and the instruction they provide results in reading proficiency for approximately 37% of students. Although researchers have established a relationship between teacher-related factors and students' performance in reading, they have not yet been able to identify the combination of teacher characteristics that best predicts teachers' intention to provide evidence-based reading instruction. The purpose of this study was to examine the relationships among teacher knowledge, teacher beliefs, and intention to provide evidence-based reading instruction using a conceptual framework that integrated the theory of planned behavior with the implicit theory of intelligence. An online survey was used to gather data from a convenience sample of 37 primary teachers in the United States to examine characteristics effective reading teachers have in common. The results of multiple regression analysis indicated different patterns for different groups of readers. For beginning readers, teachers' behavioral beliefs was the only significant predictor of intention to provide evidence-based reading instruction. For struggling readers, teacher knowledge of reading disabilities was the only significant predictor of intention. This study provided additional evidence of deficits in teachers' knowledge of basic language concepts and reading disabilities. Identifying teacher characteristics that influence students' reading proficiency outcomes may inform efforts to improve professional development and teacher preparation programs to better support and prepare teachers to ensure successful reading outcomes for all children.

Racism in the United States is persistent and its negative effects are widespread. The social hierarchy in the United States positions White people as the dominant culture and Black people, among other races, as a minority culture. Current literature provides insight into explicit and implicit individual expressions of racism; however, very little research clarifies the effects racism has on the continuance and structure of the social race hierarchy. This study utilizes social gender hierarchy research to investigate how racism-induced hostility toward the dominant culture relates to an individual's perception of the stability of the race hierarchy. This quantitative survey study compared a prime versus a non-prime condition. In the prime condition, Black participants (n = 129) were presented with racist statements to elicit a "hostility toward White individuals" response. A 6-point Likert-type scale quantified participants' perceptions of the stability of the race hierarchy. A one-way between subjects ANOVA was conducted by comparing the perceived stability means as measured by the Race Hierarchy Scale. Contrary to expectation, the prime did not produce a statistically significant change in the perceived stability of the race hierarchy. The data did reveal a chronic individual perception of the race hierarchy as unchanging. This study contributes to positive social change by illuminating social structure aspects and how individual perception functions to maintain the race hierarchy in America. This knowledge will help direct future research, policy makers, the legal system, and the private sector. Attempting to understand the effects of racism from the perspective used in this study, may encourage other researchers to generate novel approaches and methods to combat discrimination.

This study examined whether the disproportionality of African American children referred to special education is influenced by the level of implicit racial bias among teachers, using the aversive racism theory. Data were collected from teachers of kindergarten through sixth grade in the Iowa City Community School District through email recruitment. Using a factorial survey design, teachers evaluated five vignettes, each with five questions mirroring the referral process to special education, an implicit and explicit racial bias measure, and demographics. Of the 307 teachers emailed, only 21 completed the full survey. The small sample size hindered the analysis due to violations of two of the major assumptions of linear regression: normality and constant variance. Due to these violations, only limited interpretations can be concluded from the linear models. A logistic regression was also completed on the referral for special education dependent variable and yielded the following significant results: The teachers who scored high on the explicit racism measure were more likely to refer a child to a special education assessment and other results revealed associations between certain characteristics and behaviors of the children and their likelihood of referral. The majority of teachers in the sample (67%) scored high in implicit racial bias but none of the models indicates a relationship between the child's race and referral to special education. The study suggests there is some connection between implicit racial bias and referrals to special education but not due to race. However, the complexity of relationships among these and other factors in both interpersonal relationships and classroom dynamics makes it necessary to further investigate this question and potentially remedy the problem of disproportionality in special education.

In a series of two experiments, the first involving 121 participants and the second 114, I investigated whether level of racial prejudice is related to performance on a cognitive task and helping behavior in participants who had just interacted with the target of their prejudice. The moderating effect of control was tested and, unlike previous research, the responses of African-American participants were studied too. It was proposed that when people interact with the target of their prejudice, they will experience stress and the aftereffects of stress will lead to a decrement in Stroop task performance and a lower likelihood of helping someone in need. Control was believed to moderate this effect such that those given control would suffer less of a performance decrement and would help more often. Data were analyzed using ANCOVA and logistic regression. Racial prejudice was found to affect European-American but not African-American Stroop performance following the interracial interaction. Control moderated this effect and also influenced whether someone helped a person in need.

This graduate project was part of a group project completed by five school and district administrators in Hillsborough County, Florida. The project began because of our passion for teachers who are able to establish a culture of care in their classrooms that support students academically but transform their learning through experiences that enable them to be more highly engaged and productive students, regardless of ethnicity, socioeconomic status, perceived academic abilities, and backgrounds. My project component looked at research on teacher expectations and their effects on student success. Why does the color of a child's skin tone trigger lower expectations by some teachers? Why does this occur? How can school leaders and teachers confront preconceived notions that create barriers for high expectations for marginalized students? Selected literature was reviewed that concentrated on perspectives on teacher attitudes, systemic biases, and teacher expectations. I applied what I learned to exploring gaps in district emphasis on diversity and equity and potential approaches to engaging teachers and school leaders in collaborative and challenging conversation. In an examination of four major district documents, the terms ‘diversity of students’, ‘cultural diversity’, ‘high expectations for all students’, ‘multicultural awareness and equity’ each appeared only once. Professional development for teachers and school leaders was needed to focus on inquiry, self-reflection, curriculum development, and instructional approaches to surface and address implicit biases that contribute to low expectations for marginalized students.

This study investigates the constructs of Derivation and Complexity and how they relate to latency. Derivation and Complexity are theoretical constructs that have been posited as two of the main factors in differences in latency to responding in implicit measures such as the Implicit Relational Assessment Procedure (IRAP) and the Implicit Association Task (IAT). This study trained participants to relate two groups of novel stimuli in a linear fashion and then tested their latency to responding to derived relations (relations based on previously trained relations, but not directly trained themselves). The study then analyzed participant's latency to responding after dividing the responses based on derivation, complexity, and phase. The study found a significant relationship between phase and latency (p=.01), derivation and latency (p=.01), and complexity and latency (p=.04). This indicates that brief, immediate relational responses are influenced by both derivation and complexity as well as practice responding and these variables should be considered in future investigations into implicit attitudes.

<p>The Particle Level set method is a successful extension to Level set methods to improve thevolume preservation in fluid simulations. This thesis will analyze how sparse volume data structures can be used to store both the signed distance function and the particles in order to improve access speed and memory efficiency. This Particle Level set implementation will be evaluated against Digital Domains current Particle Level set implementation. Different degrees of quantization will be used to implement particle representations with varying accuracy. These particles will be tested and both visual results and error measurments will be presented. The sparse volume data structures DB-Grid and Field3D will be evaluated in terms of speed and memory efficiency.</p>

Is it possible to learn without awareness? If so, what can learn without awareness, and what are the different mechanisms that differentiate between learning with and without consciousness? How can best measure awareness? Here are a few of the many questions that I have attempted to investigate during the past few years. The main goal of this thesis was to explore the differences between conscious and unconscious learning. Thus, I will expose the behavioral and computational explorations that we conducted during the last few years. To present them properly, I first review the main concepts that, for almost a century now, researchers in the fields of neuroscience have formulated in order to tackle the issues of both learning and consciousness. Then I detail different hypotheses that guided our empirical and computational explorations. Notably, a few series of experiments allowed identification of several mechanisms that participate in either unconscious or conscious learning. In addition we explored a computational framework for explaining how one could learn unconsciously and nonetheless gain subjective access to one’s mental events. After reviewing the unfolding of our investigation, I detail the mechanisms that we identified as responsible for differences between learning with and without consciousness, and propose new hypotheses to be evaluated in the future.

Syftet med studien är att belysa åtta lärares vägar till fostran av elever i klassrummet. I bakgrunden finns, förutom en kort inledning om mitt intresse för analyserat område en begreppsutredning där jag definierar för studien centrala begrepp. I litteraturdelen presenteras både normativ och deskriptiv litteratur då tidigare emprisk forskning finns i begränsad mängd. De refererade källorna är av både äldre och nyare karaktär. Aktuella variabler i urvalet är lärares kön, undervisningsstadium, antal år i yrket och skolans upptagningsområde (status och typ av bebyggelse). Datainsamlingen har skett med en etnografisk metod där observationer, informella intervjuer och formella intervjuer har följt varandra. Analysen har skett med hjälp av procedurer som hämtats från grounded theoryansatsen där kodning och kategorisering av data har följt metodens mönster. De kategorier som växt fram är ett steg på vägen till en teorigenerering. Resultatet visar att det finns två huvudkategorier då det gäller lärares vägar till fostran, explicit och implicit påverkan. Explicit påverkan sker i form av värderingsöverföring och negativ och positiv förstärkning. Implicit påverkan sker med hjälp av det sociala klimatet, arbetssättet och materiella miljön. Studien visar att lärare är personliga i sin fostran av elever och att de fostrar på både ett medvetet och ett omedvetet sätt. Studien bekräftar annars den refererade litteraturen vad gäller lärares vägar till fostran av elever i klassrummet.

In the subject of Computational Fluid Dynamics (CFD), there seems to be small number of important progress in the pressure-based methods for several decades. Recent studies on the implicit coupled algorithms for pressure-based methods have brought a new insight. This method seems to provide a huge reduction in the solution times over segregated methods. Fully implicit coupled algorithm for pressure-based methods is very new subject with only few papers in literature. One of the most important work in this area is referenced as [1] in this thesis. Another source of information about the method comes from a commercially available code FLUENT which includes the algorithm as an option for pressure-based solver. However the algorithm in FLUENT does not seem to be a fully implicit with a little information in its manual. In this thesis, a fully implicit coupled pressure-based solver is developed mainly based on the available literature. The developed code is succesfully tested against some test cases.
