Consider a simple model of an age-structured population with two age-classes and stochastically varying survival rate of young. Let $m_{1,y},m_{2,t}$ be birth rates per capital and $P_{1,t}$ be a survival rate. egin{eqnarray} left( egin{array}{clr} N_{1,t+1}N_{2,t+1} end{array} ight) = left( egin{array}{clr} m_{1,t+1} & m_{2,t+1} P_{1,t+1} & 0 end{array} ight) left( egin{array}{clr} N_{1,t}N_{2,t} end{array} ight) end{eqnarray} we want to study the large term behavior of $(N_{1,t},N_{2,t})$ the age-structured population through the theory of random matrix product.

This thesis aims to analyze how Native American tradition storytelling functions in the life narratives of Leslie Marmon Silko and Linda Hogan¡XStoryteller and The Woman Who Watches over the World¡Xto portray the formation of the self which is inseparable from the themes of the stories that the authors constantly center on. I categorize their stories into three spheres¡Xthe land, the community and the myth¡Xand in so doing illustrate three dimensions of the self: the land-based self, the collective self and the mythical self. Through writing about the land, the community and the myth, indirect ways of self-telling can be observed and is worth further discussion. This thesis argues that it is through this indirect writing technique that Silko and Hogan are allowed to disclose their private selves without violating the Native American tradition and to turn the self-telling into a means of speaking for the community. In the end, this thesis will compare the selves that Silko and Hogan present in each dimension and point out that Silko¡¦s self is community-based while Hogan¡¦s self centers on the entire humanity.

The Leslie Street Spit is a five kilometre rubble breakwater on the eastern waterfront of Toronto. Built during the mid-twentieth-century as an infrastructural add-on to the existing Port Lands Industrial District, the artificial peninsula was a lakefilling project made to realize the city???s ambitious desire for economic prosperity and world-class prestige by expanding its existing harbour facilities. With the decline of Toronto???s shipping industry, the Leslie Spit remained an active dump site for urban clean fill until it was unexpectedly colonized by flora and fauna during the 1970s. The site is now recognized as an important local and international environmental resource. Visitors to the Leslie Spit experience a diverse landscape of ecosystems and industrial rubble helded by the city as a symbol of environmental revival within a former industrial region undergoing another phase of urbanization. While the local aesthetic experience of the headland is pleasurable and aligns with the reinvention of Toronto as am environmentally conscious and sustainable city, human visitors remain psychologically and physically removed from the inhabiting non-human life. Occasionally, the desire to conserve and preserve the natural world requires a separation between humans and non-humans. This relationship is carried out in varying degrees on the Leslie Spit. This thesis documents events at the headland where the human/non-human divide is rigidly enforced or left ambiguous. The purpose of the thesis is not to treat the headland as an eccentric spectacle, but to investigate the unexpected coexistence between humans and non-humans.

A study of the flora of Leslie Gulch Malheur County, Oregon was undertaken to elucidate the relationships of the flora and of the endemic species in the flora, and to determine if these endemic species are restricted to their present distribution by chemical factors of their substrate. A checklist of native plants and a description of the major communities was made and floristic relationships were studied. Chemical and mineralogical tests such as emission spectrography, x-ray diffraction and cation-exchange capacity as well as physical tests such as particle-size distribution and gravimetric water content were performed. The results of the tests gave no indication of any chemical factor which may restrict the distribution of plants. A zeolite, heulandite, is present in 'the ash-tuff which is the substrate for the endemic species Mentzelia packardiae Glad and Senecio ertterae Barkely. However, this would not restrict plant growth. It was concluded that the distribution of the endemics Senecio ertterae Barkley, Mentzelia packardia Glad, Ivesia rhypara Ertter & Reveal, Eriogonum novonudum Peck, and to some extent Astragalus sterilis Barneby and Trifolium owyheense Gilkey is determined primarily by physical factors of their substrates, and that they are pioneer species which may be competitively excluded from normal sites. Artemisia packardiae Grimes & ertter ined. is a species which is restricted by a diminishing relic habitat. The flora of Leslie Gulch has been complicated by interaction of a northern mesic association and a southern xeric association. The endemic species Mentzelia packardiae and Senecio ertterae are recent species which evolved from a southern Great Basin flora which has moved north with the retreat of the last ice sheets. Ivesisa rhypara and artemisia packardiae are recent species which evolved from a northern flora which followed the retreat of the ice sheets north.
