High-Stakes Testing Under The No Child Left Behind Act: How Has It Impacted School Culture?, Rashel Anderson Tingey Jul 2009

High-Stakes Testing Under The No Child Left Behind Act: How Has It Impacted School Culture?, Rashel Anderson Tingey

Theses and Dissertations

The purpose of this study was to investigate the impact of high-stakes testing under the No Child Left Behind (NCLB) Act on school culture. Individual interviews and focus groups were conducted with first grade through sixth grade teachers and principals from two of Nebo School District's schools located in Utah. Their responses were categorized into twelve themes. Most of the teachers and principals reported that high-stakes testing negatively impacted student and teacher motivation, teaching and learning, and curriculum. They also discussed negative effects of the application questioned the accuracy of high-stakes testing. Fewer teachers and principals communicated positive effects of …

The Hurtful Relationship: A Longitudinal Study Of Relational Aggression And Physical Health In Marriage, Matthew P. Martin Jul 2009

The Hurtful Relationship: A Longitudinal Study Of Relational Aggression And Physical Health In Marriage, Matthew P. Martin

Theses and Dissertations

Previous literature has examined the link between overt marital conflict and physical health and found that negative interactions in marriage may lead to poorer health. Moreover, recent studies have identified relational aggression as a type of covert marital conflict. However, none have tested for effects of relational aggression on physical health in marriage. The purpose of this research is to further study this type of conflict by examining longitudinal dyadic data to determine how subtle, indirect marital conflict like relational aggression affects the health of spouses. Data from 316 couples, from the first two waves of the BYU Flourishing Families …

Structural Interactions Between The Α3Β1 Integrin And Mmp-2: A Potential Functional Role In Cell Adhesion, James Bowman Jul 2009

Structural Interactions Between The Α3Β1 Integrin And Mmp-2: A Potential Functional Role In Cell Adhesion, James Bowman

Theses and Dissertations

During cardiac development and in cardiac disease changes in hemodynamic load initiate events leading to remodeling of the ECM. This study addresses the hypothesis that interactions between Integrins and Metalloprotienases function to modulate cell adhesion in the cultured cardiac fibroblast. The fibroblast is positioned to detect and respond to changes in the mechanical load on the heart. Functionally the cardiac fibroblast is the primary cell type responsible for the production, maintenance, and remodeling of the cardiac interstitium. Matrix Metalloproteinases, specifically the Gelatinases, are expressed in concert during development and in disease with changes in the hemodynamic loading of the heart. …

Development Of A Mangrove Quality Index In Tampa Bay, Florida, Monetta S. Wilson Jul 2009

Development Of A Mangrove Quality Index In Tampa Bay, Florida, Monetta S. Wilson

USF Tampa Graduate Theses and Dissertations

Mangroves are an important resource. They provide a breeding ground for commercially and recreationally important fish, protect shorelines from erosion and improve coastal water quality. Historically, mangroves were undervalued, leading to a loss of 35% of mangroves worldwide and 44% in Tampa Bay due to anthropogenic stressors. Efforts to protect and restore mangroves have led to a variety of management programs. In Tampa Bay the main management program is the Tampa Bay Estuary Program (TBEP). The program has identified the need for simple and easy to use assessment tools to track mangrove quality and aid in mangrove quality. There are …

Evolution And Maintenance Of Plumage Polymorphism: The Case Of The Red-Footed Booby (Sula Sula), Patricia Carvalho Baiao Jul 2009

Evolution And Maintenance Of Plumage Polymorphism: The Case Of The Red-Footed Booby (Sula Sula), Patricia Carvalho Baiao

Dissertations

The red-footed booby (Sula sula) is considered one of the most polymorphic seabirds, with three recognized major adult plumage types: (1) white; (2) white-tailed brown; and (3) brown, and several degrees of intermediates. The ratio of these color morphs varies among populations, with the white morph typically predominating. However, there are a few populations that present an inversed ratio of color morphs, such as Isla Europa in the Indian Ocean and the Galapagos archipelago, with the white-tailed brown or brown morphs predominating. I studied natural populations of red-footed boobies from three geographic locations, namely, the Galapagos archipelago, Johnston Atoll in …

Asymptotic Dynamics Of Attractive-Repulsive Swarms, Andrew J. Leverentz '08, Chad M. Topaz, Andrew J. Bernoff Jul 2009

Asymptotic Dynamics Of Attractive-Repulsive Swarms, Andrew J. Leverentz '08, Chad M. Topaz, Andrew J. Bernoff

All HMC Faculty Publications and Research

We classify and predict the asymptotic dynamics of a class of swarming models. The model consists of a conservation equation in one dimension describing the movement of a population density field. The velocity is found by convolving the density with a kernel describing attractive-repulsive social interactions. The kernel’s first moment and its limiting behavior at the origin determine whether the population asymptotically spreads, contracts, or reaches steady state. For the spreading case, the dynamics approach those of the porous medium equation. The widening, compactly supported population has edges that behave like traveling waves whose speed, density, and slope we calculate. …

Site- And Species-Specific Patterns Of Metal Bioavailability In Edible Plants, Hollydawn Murray, Karen Thompson, Sheila Macfie Jul 2009

Site- And Species-Specific Patterns Of Metal Bioavailability In Edible Plants, Hollydawn Murray, Karen Thompson, Sheila Macfie

Biology Publications

Differences in metal uptake between plant species and soil types were compared to assess the safe use of mildly contaminated soils for the growth of edible food crops. Accumulation of metals in five plant species grown in each of three field soils and a commercial soil were evaluated in a controlled environment room. Metal bioavailability varied more with plant species than with type of soil. Among a number of physical and chemical soil properties that were determined, high metal content and low percent organic matter were the best predictors of increased metal bioavailability. Contamination levels of metals measured in soil …

Growth And Differentiation Of The Larval Mosquito Midgut, Kathryn Ray, Maria Mercedes, Doris Chan, Chi Yan Choi, James T. Nishiura Jul 2009

Growth And Differentiation Of The Larval Mosquito Midgut, Kathryn Ray, Maria Mercedes, Doris Chan, Chi Yan Choi, James T. Nishiura

Publications and Research

Factors affecting larval growth and nutrition have consequences on adult fecundity. Since the mosquito larval midgut is the primary organ of digestion and nutrient absorption, factors that affect the growth and development of the midgut may have potential consequences on the reproductive potential of the adult. To gain a better understanding of mosquito midgut development the growth and metamorphic remodeling of the Aedes aegypti L. and Culex pipiens L. (Diptera: Culicidae) midguts were investigated. Cytological evidence was obtained suggesting that, in both the anterior and posterior Ae. aegypti larval midgut, diploid regenerative cells give rise to new endoreplicating cells that …

Predictive Archaeological Modeling Using Gis-Based Fuzzy Set Estimation: A Case Study In Woodford County, Kentucky, Philip B. Mink, John Ripy, Keiron Bailey, Ted H. Grossardt Jul 2009

Predictive Archaeological Modeling Using Gis-Based Fuzzy Set Estimation: A Case Study In Woodford County, Kentucky, Philip B. Mink, John Ripy, Keiron Bailey, Ted H. Grossardt

Kentucky Transportation Center Faculty and Researcher Publications

Analytic predictive archaeological models can have great utility for state Departments of Transportation, but it is difficult to model the likelihood of prehistoric settlement using geographical proxy predictor variables because of the complexity of how settlement choices were actually made, and the complex interaction between these variables using GIS. In many cases classic statistical modeling approaches require too much data to be useful. This research reports on a preliminary predictive model that combines Spatial Analyst and fuzzy logic modeling to capture expert archaeological knowledge and convert this into predictive surface. A test area was defined in Woodford County, KY and …

Autonomy-Dependency Paradox In Organization-Public Relationships: A Case Study Analysis Of A University Art Museum, Christopher E. Wilson Jul 2009

Autonomy-Dependency Paradox In Organization-Public Relationships: A Case Study Analysis Of A University Art Museum, Christopher E. Wilson

Theses and Dissertations

This study presents an exploration of the autonomy-dependence paradox inherent in organization-public relationships that is informed by paradox theory, structuration theory and scholarly and philosophical literature on authenticity. These theories suggest that relationships between organizations and their publics are defined by interdependence, or the centripetal and centrifugal forces of autonomy and dependence that cause tensions that can influence the decision making of the relational partners. They also suggest that organizations must use their agency, their knowledge of relational structures, and their understanding of their authentic selves to manage their own behavior and communication rather than that of their publics. The …

Portrayal Of Older People In Disney Live Action Films From The 1990s And 2000s, Jennifer Gail Martin Jul 2009

Portrayal Of Older People In Disney Live Action Films From The 1990s And 2000s, Jennifer Gail Martin

Theses and Dissertations

Children as young as three years old are scared of the idea of growing old, and negative stereotypes about older people have started to develop by the time children enter elementary school. Negative stereotyping of older characters has been found to be prevalent in all forms of media. Because children use media to figure out who they are and what the world is like, this study looks at some of the most popular films of the past two decades aimed toward children. This study is a content analysis of older major and minor characters from the 60 top grossing Disney …

The Subjective Experience Of Pms: A Sociological Analysis Of Women’S Narratives, Christiana B. Chekoudjian Jul 2009

The Subjective Experience Of Pms: A Sociological Analysis Of Women’S Narratives, Christiana B. Chekoudjian

USF Tampa Graduate Theses and Dissertations

The phenomenon known as premenstrual syndrome (PMS) has been researched across many disciplines including Psychology, Women's Health, Women's Studies and Sociology. It has been researched as a personal issue, a health issue, a psychological issue, and a political issue. Underlying these approaches to the study of PMS are two basic paradigms: the medical model and the social constructionist model. A rather polarized debate has emerged between the two. While both approaches have contributed to research on PMS, neither paradigm has focused particular attention on what PMS is and what it means from the perspective of the women who experience it. …

Subdivided By Faith? An Historical Account Of Evangelicals And The City, Mark T. Mulder, James K.A. Smith Jul 2009

Subdivided By Faith? An Historical Account Of Evangelicals And The City, Mark T. Mulder, James K.A. Smith

University Faculty Publications and Creative Works

In an echo of Michael Emerson and Christian Smith’s study of evangelicals and the racialized society (detailed vividly in Divided by Faith), Mark T. Mulder and James K. A. Smith attempt to trace the history and literature concerning evangelicals and their relationship to the city. While there exists an interesting literature about general urban antipathy in the U.S., the authors contend religion remains a salient and under-examined component within that phenomenon. This paper calls for more theologically-nuanced studies regarding evangelicals, anti-urban bias, and geographical habits. Mr. Mulder is Assistant Professor of Sociology and Mr. Smith is Associate Professor of Philosophy …

Using Family Centered Systems Theory To Bridge The School And Family Gap In Special Education: A Review Of The Literature, Brandon Beard Jul 2009

Using Family Centered Systems Theory To Bridge The School And Family Gap In Special Education: A Review Of The Literature, Brandon Beard

Special Education Masters Program Theses

In this review I looked at 22 articles that explored two of the primary interventional perspectives used when addressing the needs of exceptional students. A number of the articles elucidate the present prevalence of student based practices in U.S. schools, administration, and legislation. The body of the literature surveys how family centered interventions can be, and are used, to better serve students by integrating the needs and concerns of the family, as well as those of the student. The review was concluded with a discussion of the importance of finding a balance between the current legislative trend which emphasizes a …
