The major conclusion of this thesis is that Henry Watterson, while representative of the Redeemer element, was the product of a Jacksonian, rather than a Whig, heritage which had an ideology quite similar to the Redeemer appeal. In determining his exact philosophy the study shows that the editor was quite different from his contemporaries in the New South in both the substance and integrity of his beliefs.

The purpose of this study was to inductively examine the content of the popular comic strip Calvin and Hobbes by analyzing its latent and subjective meaning to discover basic social psychological issues associated with family recreation. The entire collection of 1,360 Calvin and Hobbes strips was evaluated using Grounded Theory techniques influenced by the art scholarship evaluation tool iconography. Review of the strip suggests one way to assess the meaning associated with time use is through preemptive retrospection by which a person looks at current experiences through the lens of an anticipated future to estimate how meaningful that time will be. Overall, Calvin and Hobbes suggests that meaningful time use is a key attribute of a life well lived. One key element of meaningful time use is time spent with family. The strip also helps us see the value in continuing to seek that meaning with family despite apparent setbacks. This analysis brought to light issues associated with gathering meaning from comic strips, which are also discussed. Recommendations are made for future research in the field.

In this research, STANAG 4285 HF modem software is implemented on TMS320C54x fixed point digital signal processor. The software is optimized in order to meet real-time operation requirements. A fractionally spaced least mean square (LMS) decision feedback equalizer (DFE) is employed for the receiver. In order to improve the convergence of the LMS algorithm a multipass technique is utilized. Based on Watterson&rsquo / s model, an HF channel simulator is employed for evaluating the performance of the modem. The simulation results show that the convergence of the LMS algorithm is improved by using multipass technique. It is also shown that the software meets the real-time operation requirements.
