'A treatise of algebra historical and practical' (London 1685) by John Wallis (1616-1703) was the first full length history of algebra. In four hundred pages Wallis explored the development of algebra from its appearances in Classical, Islamic and medieval cultures to the modern forms that had evolved by the end of the seventeenth century. Wallis dwelt especially on the work of his countrymen and contemporaries, Oughtred, Harriot, Pell, Brouncker and Newton, and on his own contribution to the emergence of algebra as the common language of mathematics. This thesis explores why and how A treatise of algebra was written, and the sources Wallis used. It begins by analysing Wallis's account of mathematical learning in medieval England, never previously investigated. In his researches on the origins and spread of the numeral system Wallis was at his best as a historian, and initiated many modern historiographical techniques. His summary of algebra in Renaissance Europe was less detailed, but for Wallis this part of the story set the scene for the English flowering that was to be his main theme. The influence of Oughtred's Clavis on Wallis and his contemporaries, and Wallis's efforts to promote the book, are explored in detail. Wallis's controversial account of Harriot's algebra is also examined and it is argued that it was better founded than has sometimes been supposed and that Wallis had direct access to Harriot's algebra through Pell. Many other chapters of A treatise of algebra contain mathematics that can be linked or traced to Pell, a hitherto unsuspected secret of the book. The later chapters of the thesis, like the final part of A treatise of algebra, explore Wallis's Arithmetica infinitorum and the work which arose from it up to Newton's foundation of modern analysis, and include a discussion of Brouncker's treatment of the number challenges set by Fermat. The thesis ends with a summary of contemporary and later reactions to A treatise of algebra and an assessment of Wallis's view of algebra and its history.

<p>This thesis deals with TV advertising strategies, namely adaptation and standardization, and with the impact of cultural homogenization on these strategies. Indeed, globalization generates the convergence of world cultures and especially of young Europeans’ cultures. This relative convergence in people’s habits, behaviour and values could allow advertisers to use more standardized advertisements without losing too much impact on the consumer. The use of standardized advertisements is interesting to create a uniform brand image, appeal to cross-border segments and, of course, make economies of scale. This thesis surveys young Europeans, represented by Swedes and Belgians, to examine their degree of cultural homogenization, i.e., if they are culturally similar enough for standardization to be effective on this group. Moreover, it compares the impact of both adapted and standardized commercials on this young European audience. This study comes to two main findings. First, the young Swedish and Belgian cultures have similarities, which standardized commercials can exploit, but also differences. This shows that we can speak about cultures’ convergence but not about a complete homogenization. Second, standardization seems to be effective - as effective as adaptation - in its appeal to young Swedes and Belgians. This shows that, given its advantages, standardization is certainly the most adequate method for targeting a young European audience. The findings for Sweden and Belgium should be valid for the whole EU. The thesis also discusses the generalization of the findings to the rest of the world and other age ranges as well as the future of commercials.</p>

The purpose of this study is to bring to the forefront the importance of black humor in the lives of African-Americans. The cultural roots of black humor began in Africa and were transported to America where Africans were forced to live as an enslaved people. Humor is a defining factor which contributed to the survival of blacks living in an oppressed state. Black people continue to live in survival mode and the researcher evaluates how black humor is a significant component to overcoming a life of adversity. All genres of literature evolve from one generation to the next. The genre of black humor is no different. This study will disclose how the dynamics of black humor evolve from the days of the enslaved entertaining the plantation masters, to the era of minstrelsy, and into the twentieth century with the rise of black comedy. Each period of black humor will demonstrate the profound effect humor has in the lives of black people.
