The Roza flow of the Columbia River Basalt group in Washington State U.S.A. extruded at about 15 Ma during intermediate geomagnetic polarity. The Roza is underlain by normal polarity flows and overlain by reversed units. The Roza is an extensive flow, up to 60 in thick. As the remanence-blocking isotherms progressed into the flow, it recorded a short continuous segment of the transitional geomagnetic field. Our studies show limited thermal remagnetization in the underlying flow, and we infer that groundwater was effective in extracting the heat. The extent of basement heating was further reduced by the insulating scoria immediately beneath Roza. Hence, the Roza flow cooled symmetrically from its top and base. Samples from the drilicores acquired drilling induced remanent magnetization (DIRM), shown to be well modelled as an isothermal remanent magnetization produced in nonuniform fields of the order of 10 mT at the rim of the drillstring. Alternating field demagnetization was usually successful in removing the DIRM. The remanence stability is higher in the top third of Roza, due to smaller magnetic particles, than in the lower two thirds of the flow, where the magnetic properties are nearly uniform. The stability profile corresponds to the entablature/colonnade subdivision. High temperature subsolidus oxidation of the titanomagnetites increased with height in the flow, altering the primary symmetric intraflow distribution. The declination of the Roza flow sampled at numerous outcrops is consistently about 189°. In a 54 m drillcore section, Roza inclinations become more negative towards the flow interior, consistent with its magnetostratigraphic position. Superimposed is a symmetric, rapid change in inclination from -2 to -15° and back to -5°. The flow's thermal history predicts that these fluctuations have a characteristic time between 15 and 60 years, such that the inclination changed at a rate of 1/2 to 2° per year, showing that the directions of this transitional field fluctuated several times more rapidly than the present geomagnetic field. However, considering the generally reduced intensity during transitions, these fluctuations might not be unusual. / Graduation date: 1990

The rhetoric of development is a dominant driving factor for intervention into the Republic of Haiti. Millions are pumped into the small black republic located in the Caribbean for development projects motivated by health, HIV/AIDS awareness, religion, and sanitation just to name a few. Yet, despite the innumerable efforts of nongovernmental organizations and donor organizations in Haiti, the country is sinking deeper and deeper into desperate conditions. The motivation for this thesis is to examine the accountability that these organizations operating in Haiti have towards the Haitian peoples who are the targeted beneficiaries. Are they involved in the development process aside from being the ?receivers? of assistance? Development projects designed and implemented without the input of the targeted communities have relatively short-lived progress and experience failure. Accountability to the constituents necessitates involving and engaging their values and community needs. The Lambi Fund is a nongovernmental organization that attributes its success to its alternative ?bottom-up? model of development. Local organizations in Haiti solicit funding, training, and guidance from the Lambi Fund with project proposals and community needs in hand. This model appears to have an impressive degree of accountability to the grassroots organizations that it serves. I analyze and assess the viability and success of this model in the context of the history and current trends of development in Haiti and elsewhere by examining both the Lambi Fund?s own claims about its programs (in print and in interviews with its principal officers) and a recent evaluation made of its programs by a third party organization. A recommendation for further research is enclosed in the conclusion.
