Examining Preservice Teachers' Performances And Pedagogies Of Practice In An Urban Classroom Through The Use Of A Simulated Learning Environment, Kelly Jennings

Electronic Theses and Dissertations

The failure to staff the nation’s classrooms with highly qualified teachers, especially those in disadvantaged schools, is a problem in American education. Novice teachers who begin teaching in urban, low-income, diverse schools leave the field of education at alarmingly high rates. Schools are not being provided with the teachers they deserve; new teachers are especially ill-prepared to meet the needs of students in high-need urban settings. In return, these lowincome schools are not retaining sufficient numbers of the teachers they do recruit. A teacher’s performance has a tremendous impact on a child’s learning and academic journey. Teacher preparation programs need …

The U.S. Environmental Movement 1890-2002: Discourse Divisions, Environmental Crisis Events, And Strategic Concessions, Wendi Kane

Electronic Theses and Dissertations

The U.S. Environmental Movement is facing a paradox: increased mobilization over the last 100 years has not been entirely effective in halting environmental degradation. This research suggests that discourse divisions among environmental movement organizations constitute a fundamental obstacle to progressive change. The discourse divisions are evident in movement organizing patterns during periods of increased environmental crisis over the history of the modern environmental movement. In addition, evidence suggests that federal environmental policy is an outcome of increased organizing among movement organizations with more transformative visions of change. However, policy outcomes from increased pressure among transformative organizations are significantly correlated with …

Multifunctional And Responsive Polyelectrolyte Nanostructures, Astha Malhotra Jan 2014

Multifunctional And Responsive Polyelectrolyte Nanostructures, Astha Malhotra

Electronic Theses and Dissertations

A polyelectrolyte complex is formed by mixing two oppositely charged polyelectrolytes in a solution. The electrostatic interactions between partially charged polymeric chains lead to the formation of a stable complex while avoiding the use of covalent cross linkers. Since complex formation can improve the stability of polyelectrolyte and metal ions in polyelectrolyte can provide various functionalities, PECs incorporated with metal ions are promising candidates for manufacturing stable and multifunctional structures. While the coordination of metal ions and polyelectrolytes has been extensively investigated in solutions and multilayer films, to our knowledge, no research has been performed to study the effect of …

Chemical Differentiation Of Human Osseous, Non-Human Osseous, And Non-Osseous Materials Using Scanning Electron Microscopy - Energy Dispersive X-Ray Spectrometry (Sem/Edx) And Multivariate Statistical Analysis, Cayli Meizel-Lambert Jan 2014

Chemical Differentiation Of Human Osseous, Non-Human Osseous, And Non-Osseous Materials Using Scanning Electron Microscopy - Energy Dispersive X-Ray Spectrometry (Sem/Edx) And Multivariate Statistical Analysis, Cayli Meizel-Lambert

Electronic Theses and Dissertations

Identification of osseous materials is generally established on gross anatomical factors; however, highly fragmented or taphonomically altered materials are often problematic and alternative methods, such as biological, histological, or chemical analysis, must be utilized. Recently, chemical methods have been proposed to sort unknown materials according to their Ca/P ratios. Ubelaker and colleagues (2002) proposed using SEM/EDX to achieve this distinction and Christensen and colleagues (2012) have validated X-ray Fluorescence Spectrometry (XRF) for this application. An alternative method of analysis involves performing principal component analysis (PCA) on element spectra to classify unknown materials based on their trace element composition. Zimmerman (2013) …
