Richmond Public Schools: Post-Court Mandated School Desegregation (1986-2006), Joshua Cole

Theses and Dissertations

In 1970, cross-town busing was court mandated to enforce school desegregation in Richmond, Virginia. Unitary status was declared in Richmond when cross-town busing ended in 1986. Richmond Public Schools (RPS) no longer operated as a dual school system for blacks and whites after 1986. Class and racial segregation continued to exist in the City of Richmond. RPS remained predominately black and poor. Socio-economic conditions of the city continued to impact the school district. Controversies, mismanagement and low academic achievement stigmatized RPS until state and federal performance measures forced the district to improve. By 2006, RPS was still segregated; however, as …

Spatial Instability Of Electrically Driven Jets With Finite Conductivity And Under Constant Or Variable Applied Field, Saulo Orizaga, Daniel N. Riahi

School of Mathematical & Statistical Sciences Faculty Publications

We investigate the problem of spatial instability of electrically driven viscous jets with finite electrical conductivity and in the presence of either a constant or a variable applied electric field. A mathematical model, which is developed and used for the spatially growing disturbances in electrically driven jet flows, leads to a lengthy equation for the unknown growth rate and frequency of the disturbances. This equation is solved numerically using Newton’s method. For neutral temporal stability boundary, we find, in particular, two new spatial modes of instability under certain conditions. One of these modes is enhanced by the strength Ω of …

Principal Efficacy: An Investigation Of School Principals' Sense Of Efficacy And Indicators Of School Effectiveness, Charles Wayne Lovell

Dissertations

At the individual school level, the responsibility for demonstrating school effectiveness lies on the shoulders of the building administrator. In fact, "it is widely accepted that good principals are the cornerstones of good schools and that, without a principal's leadership efforts to raise student achievement, schools cannot succeed" (Tschannen-Moran & Gareis, 2004, p. 573). However, federal, state, and local mandates have increased the pressure on school administrators to demonstrate effectiveness. As a result, the work of school administrators has changed. Furthermore, Fullan (2003) identifies a trend that demonstrates a dramatic decrease in the principal's perceptions of effectiveness, authority, trust, and …

Entropy And Certainty In Lossless Data Compression, James Jay Jacobs

Dissertations

Data compression is the art of using encoding techniques to represent data symbols using less storage space compared to the original data representation. The encoding process builds a relationship between the entropy of the data and the certainty of the system. The theoretical limits of this relationship are defined by the theory of entropy in information that was proposed by Claude Shannon. Lossless data compression is uniquely tied to entropy theory as the data and the system have a static definition. The static nature of the two requires a mechanism to reduce the entropy without the ability to alter either …

Reactor R&D: Synthesis And Optimization Of Metallic Nitride Fullerenes And The Introduction Of Two New Classes Of Endohedral Metallofullerenes, Metallic Nitride Azafullerenes And Oxo-Metallic Fullerenes, Curtis Earl Coumbe

Dissertations

Metallic nitride fullerenes (MNFs) were discovered in 1999. This class of endohedral fullerenes show promise in a new diverse range of useful applications. Since then, focus has shifted to the selective synthesis of these molecules with yields that would accommodate adequate sample distribution. Using the electric arc method, the traditional yield of these molecules has been very low (i.e. < 5 mg), and only a small percentage of the fullerene products (i.e. < 5%). This dissertation introduces the novel CAPTEAR (Chemically Adjusting Plasma Temperature, Energy, And Reactivity) method that allows the targeted synthesis of MNFs in high purity and yield. This method utilizes a nontraditional oxidizing method for fullerene synthesis that has not only provided optimization of MNFs, but also resulted in the discovery of two new classes of fullerenes: metallic nitride azafullerenes (MNAFs) and oxo-metallic fullerenes (OMFs). Evidence suggests that the nitrogen of the MNAF cage provides stability for the trimetallic nitride clusters, while the OMFs are the first fullerenes to encapsulate oxygen and incorporate a seven atom cluster inside a Cgo cage.

Other efforts to increase yields resulted from scaling up production of fullerenes by using larger quantities of starting materials. These larger quantities required energy (electrical current) beyond the capacity of the traditional electric arc generator. Therefore, a new electric arc generator …
