FCC minority broadcast ownership policies-- a critical race theory analysis of judicial assumptions in court decisions : the convergence of race and law

This dissertation used critical race theory as a basis to probe legal and regulatory transitions in the area of minority ownership and their implications for marketplace diversity and public interest. Through the examination of judicial decisions involving minority broadcast ownership this dissertation analyzed the expressed or implied assumptions of the judiciary in reaching those decisions, provided a critical analysis of those assumptions, discussed the implications and results of those assumptions on minority broadcast ownership, and suggested approaches to promote diversity and minority ownership in a deregulated media environment. Both primary and secondary authorities were integral to this research. Overall, analysis took place in three parts. First, there was a collection of United States district court, appellate court, and Supreme Court cases in the area of minority ownership and minority ownership policies promoted by the FCC. Second, analysis of cases consisted of reviewing majority and dissenting opinions. Placing majority and dissenting opinions in the framework of critical race theory, the study continued with determining the judicial rationales and arguments

Predicting transcription factor binding sites using local over-representation and comparative genomics

BACKGROUND: Identifying cis-regulatory elements is crucial to understanding gene expression, which highlights the importance of the computational detection of overrepresented transcription factor binding sites (TFBSs) in coexpressed or coregulated genes. However, this is a challenging problem, especially when considering higher eukaryotic organisms. RESULTS: We have developed a method, named TFM-Explorer, that searches for locally overrepresented TFBSs in a set of coregulated genes, which are modeled by profiles provided by a database of position weight matrices. The novelty of the method is that it takes advantage of spatial conservation in the sequence and supports multiple species. The efficiency of the underlying algorithm and its robustness to noise allow weak regulatory signals to be detected in large heterogeneous data sets. CONCLUSION: TFM-Explorer provides an efficient way to predict TFBS overrepresentation in related sequences. Promising results were obtained in a variety of examples in human, mouse, and rat genomes. The software is publicly available at

Drag of Prestone and Oil Radiators on the YO-31A Airplane

At the request of the Army Air Corps tests were conducted on a mock-up of the YO-31A airplane to determine the drag of the prestone and oil radiators. The drag of the airplane was determined with both radiators exposed on the lower surface of the fuselage; with each radiator exposed; and with no radiators. The results show that at 120 m.p.h the oil radiator accounted for 2.8 percent of the drag of the complete airplane; the prestone radiator 8.3 percent; and both radiators together, 11.8 percent
