Both public relations practitioners and journalists believe they are equal partners in the dissemination of information. Only 34.6 percent of public relations practitioners believe journalists have high morals and ethics, and are honest with public relations practitioners. Over 50 percent of …

Multiculturalism And The Media: Using Racially Motivated Films To Increase Attitudes About Race, Nacovin J. Norman

Theses and Dissertations

The attempt to answer the question, "Do racially motivated movies (media) affect young adolescents' attitude on multiculturalism?" was capable of yielding significant results. The study required sampling a population of seventh and eighth graders. The participants demonstrated variability in regards to ethnicity, age, social class, and level of cognitive functioning. Using the paired sample t, ANOVA and various non-parametrical tests, the answer to the question seems to correspond with the research. Therefore, using media can have a significant and an immediate effect, on not only multiculturalism, but human behavior as well.

Post-Processing Of Low Dose Mammography Images, Jesung Kim

Theses and Dissertations

In mammography, X-ray radiation is used in sufficient doses to be captured on film for cancer diagnosis. A problem lies in the inherent nature of X-rays to cause cancer. The resolution of the images obtained on film is directly related to the radiation dosage. Thus, a trade-off between image quality and radiation exposure is necessary to ensure proper diagnosis without causing cancer. A possible solution is to decrease the dosage of radiation and improve the image quality of mammograms using post- processing methods applied to digitized film images. Image processing techniques that may improve the resolution of images captured at …

Evaluation And Analysis Of Array Antennas For Passive Coherent Location (Pcl) Systems, Baris Calikoglu

Theses and Dissertations

Passive Coherent Location (PCL) systems use a special form of a radar receiver that exploits the ambient radiation in the environment to detect and track targets. Typical transmissions of opportunity that might be exploited include television and FM radiobroadcasts. PCL implies the use of a non-radar electromagnetic sources of illumination, such as commercial radio or television broadcasts also referred as transmitters of opportunity. The use of such illumination sources means that the receiver needs to process waveforms that are not designed for radar purposes. As a consequence, the receivers for PCL systems must be much more customized than traditional receivers, …

"Ja, Ich Habe Einen Deutschen Pass, Aber Ich Bin Doch Schwarz": Black German Confrontations With Blackness, Valerie M.C.E. Dube-Luvai

Theses and Dissertations

This thesis explores the complexities of constructing a German identity as a black German. The recent emergence of Germany's black minority group was generally perceived as an opportunity to reevaluate Germanness as it has been understood in the past. However, this thesis shows that a reevaluation of Germanness lacks full support because traditional German ideals of racial superiority continue to exist in the consciousness of all Germans - black and white. This suggests that theories of racial superiority continue to determine belonging and identity construction in Germany. Above all, the presence of Western racial ideology in black German identity construction …

A Comparison Of Coalescent Estimation Software, Kristen Piggott Shepherd

Theses and Dissertations

Coalescent theory is a method often used by population geneticists in order to make inferences about evolutionary parameters. The coalescent is a stochastic model that approximates ancestral relationships among genes. An understanding of the coalescent pattern of a sample of sequences, along with some knowledge of the mutations that have occurred, provides information about the evolutionary forces that have acted on the population. Processes such as migration, recombination, variable population size, or natural selection are the forces that affect the genealogies and lead to genetic variability in a sample. Coalescent theory provides a statistical description of the variability in the …
