This study investigates the transition from hunting and gathering economies to mixed economies involving both agriculture and hunting and gathering. Specifically, the problem of when, why, and how the transition to agriculture occurred in the arid-semiarid river basins of southeastern Arizona is explored. Modern environmental conditions are described, and the nature and sources of climatic, biotic, and fluvial systemic variability are considered. Anthropological and ecological models of hunter-gatherer adaptations to arid environments are used to reconstruct the general subsistence economy of preagricultural societies in the region, and to portray the process of the spread of agricultural production strategies. Two models of the transition are presented, one involving the adoption of agriculture by indigenous hunting-gathering societies, and the other involving the arrival of immigrant societies already practicing agriculture to a significant degree. Previous studies of the transition to agriculture in the American Southwest are reviewed, and new data are presented from excavated Late Archaic (ca. 3000-2000 BP) sites in southeastern Arizona. These data show that agriculture appeared by at least 2800 BP in this area, and that it spread rapidly across the American Southwest. It was already an important subsistence strategy and was associated with semisedentary village sites that have no known predecessors in the archaeological record. It is concluded that the adoption of agriculture, with its associated storage technology, is an important strategy by which human populations can mitigate some of the risks associated with foraging in an environment characterized by predictable seasonal variation in resource availability and unpredictable, climatically-induced fluctuations in the productivity of wild resources over time.

This dissertation investigates the works of two Black female writers: Flora Nwapa(African and Nigerian) and Zora Neale Hurston (African American). Although theycome from different geographical regions, both writers use the same rchetypal patterns to create strong female protagonists. By characterizing protagonists in their novels from an African religious cultural perspective, both authors dismantle the stereotypical images of how black women are typically portrayed in fiction. Using Jung's theory of the collective unconscious and archetypal criticism the study finds that both authors create black female protagonists who are wise, resilient, decisive, courageous, independent, and risk-taking; the women who, through their self-discovery journeys, are neither defined by nor in oppositional relationships with the males in their lives. The study compares how the qualities of two archetypal goddesses, Uhamiri of the Igbo cosmology and Oya of the Yoruba cosmology, are personified through the personalities of the two female protagonists in Nwapa's Efuru and Hurston's Their Eyes Were Watching God, respectively. Using strong mythical females as templates, this research explores the ways in which the authors have defined their female characters, thus providing an alternative strategy for defining and analyzing black female characters in fiction. The study asserts that literary interpretation of Africana women should include the cultural realities associated with the African religious framework in order to capture the full essence of their humanity. In addition, African feminist thought, unlike Western feminist theory, provides a more realistic model of discourse on Africana women's selfidentity. Examining Africana women from these perspectives, as opposed to analyzing them based on European standards, is an effective method of discrediting stereotypical images that continue to plague the portrayal of black women in fiction. When black women in fiction are explored from this vantage point, the literary work sends a message of cultural authenticity and preservation that elevates Africana women, expanding their functions and positions in society beyond traditional roles.
