Quantified Stability Investigations for Reaction-Diffusion Systems

The main focus of this thesis lies in the investigation of the properties of stationary solutions to reaction-diffusion systems. Using the computer-assisted approach the questions on the stability and existence of stationary solutions of pattern formation, spruce budworm, predator-prey and competition models are answered. Moreover, granted that the stationary solution is stable, a computer-assisted method for the quantification of its domain of attraction is proposed

News to make a difference : the environment and The 4th estate, 1969-1977

iv, 248 leaves : ill. ; 29 cm.Includes abstract.Includes bibliographical references (leaves 234-248).This thesis is the first lengthy study of The 4th ESTATE, an alternative newspaper published in Halifax, Nova Scotia 1969-1977. It covers the work of journalists in both the alternative and the daily press in the 1960s and 1970s. An examination of print media in the years 2006-2008 puts the thesis into context. The editors of The 4th ESTATE thought of themselves as a new voice in Halifax and the Maritimes, covering such themes as environmentalism (which is covered in detail in the thesis), poverty, women's rights, the Black movement, mental health, and sexual orientation. The editors contended that Halifax needed a new newspaper in town, one that would be truthful and also activist in its approach. The paper became well known for giving a voice to the underdogs of society. The thesis also covers politics in Nova Scotia during the time that The 4th ESTATE was published
