This study is participant observational research focused on the culture of one successful alternative education program. The survey of the literature showed that the problem of high school dropouts is one of numbers and persistence over time. Most research in the past attempted to list characteristics of high school dropouts or elements of successful alternative education programs. Researchers such as Wehlage (1986) and Catterall (1987) have begun to look at a different approach. Their work looks at schools as systems and suggests that educators should direct their attention to the interaction of the school environment with the characteristics of the students. This view fits into a body of work that looks at schools and classrooms as microcultures. The work presented here looks at an alternative education program as a microculture and asks "What appears to be the distinguishing microculture created by the participants of Tri City Alternative Program?" The researcher collected data from interviews, observations, student projects and work, staff meetings, and program materials and records. The data were analyzed and organized to find patterns of behavior and interactions and to determine the meaning the participants attached to their interactions. The elements that distinguish the microculture of the alternative education program were divided into the features of the context and the features of the interactions. The elements of the context were described by the physical setting, the daily instructional schedule, and the non-instructional daily schedule. The elements of the interaction were described by clearly stated expectations, staff and student attention to culture, sense of caring and defining competence, and sense of humor. The researcher concludes by proposing three future areas of work. One is to develop a model of synchronization between the context and interactions of educational programs. The second is to complete additional cultural studies of high school dropouts. The last recommendation is to train teachers and students to use participant observational techniques in their classrooms to build their understanding of their own microcultures.

The construct internal-external locus of control was utilized to examine the Soviet Pentecostal refugees' perception of life experiences in the United States as defined by three dimensions: social, economical, and political. Unlike the majority of immigration research, which focuses on structural variables, this research further addressed the concept of acculturation as a long term process of resettlement. Subjects completed an anonymous forced choice questionnaire consisting of the Rotter (1966) locus of control instrument scale. Pearson Product moment correlation coefficients were calculated to examine the strength of the relationships between the internal-external locus of control scores and five factor analyzed life experience categories. Positive and sometimes strong correlations could be found between the internal-external locus of control scores and the five life experience factors. All five hypotheses were confirmed by the results.

Large-volume silicic ignimbrites erupt from reservoirs that vary in composition, temperature, volatile content and crystallinity. The 9.7 Ma Devine Canyon Tuff (DCT) of eastern Oregon is a large-volume (>250 km3), compositionally zoned and variably welded ignimbrite. The ignimbrite exhibits heterogeneous trace element compositions, variable volatile content and crystallinity. These observations were utilized in the investigation into the generation, accumulation and evolution of the magmas composing the DCT. Building off previous research, pumices were selected from the range of trace element compositions and analyzed with respect to crystallinity, mineral abundances and assemblages. The DCT displays a gradational trace element enrichment and decrease in crystallinity from least evolved, dacite, at ~22% crystals to most evolved high-silica rhyolite at 3% crystals. Two distinct mineral populations of feldspar and clinopyroxene were identified in previous work, one belonging to the rhyolitic magma and the other to the dacitic magma. Volatile content derived from melt inclusion Fourier Transform Infrared (FTIR) spectrometer analysis revealed an increase in water content from 1.2 to 3.7 wt.% in the most evolved rhyolite. The DCT exhibits low and variable δ18O signatures, 4.52‰ to 5.76‰ , based on δ18O values measured on quartz and sanidine. Low δ18O signatures of all DCT rhyolites suggest the incorporation of hydrothermally altered crust into the melt. Furthermore, quartz phenocrysts from all high-silica rhyolite groups display dark oscillatory zoned cores and Ti-rich bright rims. These data provide insight into how these magmas were generated and subsequently stored in the crust. Commonalities of petrographic and compositional features among rhyolites, especially the zoning characteristics of quartz phenocrysts, exclude the possibility of storage and evolution in multiple reservoirs. Envisioning a scenario where all magmas are stored within a single reservoir prior to eruption and assuming rhyolites A and D are the product of partial melting. The mixing of A and D rhyolites produced rhyolite B, and subsequent mixing of intermediate rhyolite B and end-member rhyolite D generated rhyolite C. However, some trace element inconsistencies, between mixing model and observed intermediate rhyolites suggest a secondary process. Post mixing, rhyolites B and C require some modification by fractional crystallization to account for LREE and other inconsistencies between mixed models and observed rhyolites. Finally, the origin of the dacite is likely through mixing of group D rhyolite and an intrusive fractionated basalt, which could have led to the eruption of the Devine Canyon Tuff.

The Dallas-Monmouth area, located in the west-central Willamette Valley, Oregon, consists of Tertiary marine and volcanic bedrock units which are locally overlain by alluvium. The occurrence of groundwater with high salinities has forced many rural residents to use public water supplies. Lithologic descriptions from driller's logs, geochemical (INAA), and x-ray diffraction analyses were used to determine alluvial facies distribution, geochemical and clay mineral distinctions among the units, and possible sediment sources. Driller's log, chemical and isotopic analysis, and specific conductance information from wells and springs were used to study the hydrogeologic characteristics of the aquifers and determine the distribution, characteristics, controlling factors, and origin of the problem groundwaters. Three lithologic units are recognized within the alluvium on the basis of grain-size: 1) a lower fine-grained unit; 2) a coarse-grained unit; and 3) an upper fine-grained unit. As indicated by geochemical data, probable sediment sources include: 1) Cascade Range for the recent river alluvium; 2) Columbia Basin plutonic or metamorphic rocks for the upper fine-grained older alluvium; and 3) Siletz River Volcanics from the west for the coarse-grained sediment of the older alluvium. The Spencer Formation (Ts) is geochemically distinct from the Yamhill Formation (Ty) and the undifferentiated Eocene-Oligocene sedimentary rock (Toe) with higher Th, Rb, K, and La and lower Fe, Sc, and Co concentrations. The clay mineralogy of the Ty is predominantly smectite (86%) while the Ts contains a more varied clay suite (kaolinite, 39%; smectite, 53%; and illite 8%). The Ty and Toe are geochemically similar, but are separated stratigraphically by the Ts. The Siletz River Volcanics is distinct from the marine sedimentary units with higher Fe, Na, Co, Cr and Sc concentrations. The Ty and Toe are geochemically similar to volcanic-arc derived sediments while the Ts is similar to more chemically-evolved continental crust material. Wells that encounter groundwater with high salinities (TDS>300 mg/1): 1) obtain water from the marine sedimentary bedrock units or the older alluvium; 2) are completed within zones of relatively low permeability (specific capacities ~5 gpm/ft); and 3) are located in relatively low-lying topographic settings. The poor quality waters occurring under these conditions may be due to the occurrence of mineralized, regional flow system waters. Aquifers of low permeability are less likely to be flushed with recent meteoric water, whereas upland areas and areas with little low permeability overburden are likely zones of active recharge and flushing with fresh, meteoric water. The most saline waters sampled have average isotopic values (6D = -6.7 ° / 00 and 60 = -1.7 ° / 00 ) very near to SMOW, while the other waters sampled have isotopic signatures indicative of a local meteoric origin. The Br/Cl ratios of most (10 of 14) of the waters sampled are within 20% of seawater. A marine connate origin is proposed for these waters with varying amounts of dilution with meteoric waters and water-rock interaction. The problem waters can be classified into three chemically distinct groups: 1) CaC12 waters, with Ca as the dominant cation; 2) NaCl waters with Na as the dominant cation; and 3) Na-Ca-Cl waters with nearly equal Na and Ca concentrations. The NaCl and CaC12 waters may have similar marine connate origins, but have undergone different evolutionary histories. The Na-Ca-Cl waters may represent a mixing of the NaCl and CaC12 waters.

The social and economic structure of Oregon was influenced by the Donation Land Law. The Congressional law conferred upon early settlers to Oregon 320 acres, 640 if married (and settled before December 1, 1850). Oregon attracted settlers who desired land and were uninterested in commercial agriculture. The Oregon settlers who took advantage of the law were in a position to create their own society and economy. The purpose of this thesis is to identify the social and economic structure created by the Donation Land pioneers and to identify their land disposition strategy. This thesis examined the fifty households that comprised the neighborhood of Fabritus R. Smith. The neighborhood is defined as the fifty households with whom Smith dealt in 1854 and 1855. The neighborhood of the 1850s was a communally based society in which production was geared for household consumption, not commercial purposes. Settlers exchanged goods locally on a market that functioned on the basis of barter and a personal monetary system. The progression of time brought changes to the social and economic structure. Lineal families working for themselves replaced nuclear families working in community as a productive force. Salem's growth, and the rise of a cash economy replaced exchange among households. Donation Land pioneers who deeded land to their children created the lineal family structure of society. The production of the lineal family remained geared for household consumption, not commercial purposes. The farmers of the second generation did not change their objective, only their strategy to meet the new economy. Two additional strategies were identified. Some Donation Land pioneers disposed of their land and used the money to pursue other ventures outside Oregon. Other Donation Land pioneers sold their land and moved to Salem.

The present paper is a descriptive study of sex offender sentencing in three Oregon counties in 1992. It examines the relationship between sentencing practices and indigent offenders. It focuses specifically on the question of offender indigent status and court ordered sex offender treatment. The study also provides information about the number of sex offenders in each of the three counties, how the offenders' sentences were determined by the courts through the use of the sentencing guidelines matrix, what type of plea was used, and what if any influence indigence had in the sentencing outcomes for the felony sex off enders in this study. Viewed from a conflict theoretical perspective, it was expected that indigent sex offenders would experience differential treatment by the courts. Two-tailed chi-square tests were computed to determine if a difference exists between sentences given indigent and non-indigent offenders. The same tests were applied to determine if there exists a difference between indigent and non-indigent in regard to the addressing of treatment in the sentence order. The tests were considered significant at the . 05 level. A significant difference was found between probation sentences and prison sentences for indigent versus non indigent offenders. Frequency scores were examined for this study by the number of indigent sex offenders that were convicted in each sample county for 1992, guilt type, guilt type and sentence, sentencing guidelines matrix score, indigence and race, and treatment by county. There is minimal information on the topic of sex offenders and the possible relationship between indigence, sentence disposition and treatment. The information contained in this study will contribute to the body of knowledge in the area of sex offenders and the results of this study will provide information useful for further research.

The abortion debate in the United States has come to split the contemporary electorate among party lines. Since the late 1970s, the Republican Party has taken a stand against abortion and has worked through various routes of legislation to pass restrictions on access to the procedure. Oregon however, provides a different interpretation of this partisan debate. Though Oregon has seen both Republican and Democratic leadership in all houses of state government and pro-life conservative groups have lobbied to restrict the procedure, no abortion restriction has been passed in the state since the United States Supreme Court invalidated many state abortion bans in 1973. This thesis analyzes the legislative history of Oregon beginning in the mid nineteenth century, when the Oregon Territory first passed an abortion ban. Oregon voters and lawmakers alike were continuously asked to debate the legality and morality of abortion. Though the state did participate in the national debate over access to abortion, made clear by dozens of attempts at restricting the procedure, Oregon's response to conservative political trends is distinctive. Oregon liberalized its abortion law before Roe was decided; and years before, prominent physicians provided abortions and advocated for reproductive health. After abortion was decriminalized, Oregon legislators protected abortion access further by rejecting all attempts to pass abortion restrictions and crafting legislation to make further restrictions more difficult to pass. Even as Republicans gained majorities in the Oregon legislature in the late 1980s and 1990s and the pro-life movement gained momentum on the statewide level nationally, Republican lawmakers remained unwilling to prioritize abortion legislation. So too, in the decades following the Roe decision, Oregon voters have rejected all pro-life attempts to restrict abortion access by ballot initiative. Instead of pointing to one explanation for Oregon's protection of abortion access, this thesis examines the societal and legislative developments that worked in tandem to create a legislative landscape that is protective of abortion.

Recent management efforts in the Smith and Bybee Lakes Wildlife Area (SBL), a 700-ha preserve in north Portland, Oregon, have included using a water control structure to suppress invasive reed canarygrass (Phalaris arundinacea L.) by flooding during spring and early summer growth periods. For the first year of managed flooding, I sought to determine: (a) the extent and distribution of reed canarygrass at SBL; (b) the effectiveness of the change in water level at suppressing reed canarygrass; and ( c) the effects of the change in water level on other plant species. I established 30 vegetation transects throughout SBL before completion of the water control structure. These transects were randomly distributed, placed perpendicularly to the shorelines of the wetlands, and had a cumulative length of 3.1 km. I measured vegetation on the transects in autumn 2003 and autumn 2004 using the line intercept method at 10-cm intervals. I surveyed the transects to generate elevation profiles, accurate to 0.15 cm, to determine depth and duration of flooding, which I correlated with vegetative changes. I also monitored inundation depth, growth, and phenological response of individual stands of reed canarygrass during the 2004 growing season.

In 1991 EPA embraced the watershed protection approach for environmental management. EPA defines watershed protection as â a strategy for effectively protecting and restoring aquatic ecosystems and protecting human health.â To encourage statewide watershed protection, EPA developed the “Statewide Watershed Protection Approach” document, which is designed to aid states in developing their own watershed protection program. The watershed protection approach is not a program or policy required by EPA, rather a flexible framework that outlines the essential elements and components of a comprehensive statewide watershed protection approach. It allows for varying conditions in a state, but attempts to ensure a consistent general approach. This paper describes the elements and components of EPA’s comprehensive statewide watershed protection framework. It then analyzes Washington, Minnesota, and Oregon’s statewide watershed protection programs, and examines how these state approaches reflect EPA's framework. In addition, the paper analyzes a case study in each of these states to explore how these statewide watershed management approaches are implemented at the local level. By analyzing states that have successfully implemented a statewide watershed protection approach, this paper aims to identify the critical elements in a statewide watershed protection approach, and identify the issues that are critical to successful local implementation. / Master of Urban and Regional Planning

acase@tulane.edu / Fault growth is often accomplished by linking a series of en echelon faults through relay ramps. A relay ramp is the area between two overlapping fault segments that tilts and deforms as the faults accrue displacement. The structural evolution of breached normal fault relay ramps remains poorly understood because of the difficulty in defining how slip is partitioned between the most basinward fault (known as the outboard fault, which includes the severed fault tip), the overlapping fault (inboard fault), and any ramp-breaching linking faults. Along the Warner Valley fault in south-central Oregon, two relay ramps displaying different fault linkage geometries are lined with a series of pluvial shorelines that record a Pleistocene paleolake regression. The inner edges of these shorelines act as paleo-horizontal datums that have been deformed by fault activity, and are used to measure relative slip variations across the relay ramp bounding faults. By measuring the elevation changes using a 10m digital elevation model (DEM) of shoreline inner edges, I estimate the amount of fault activity on severed fault tips. In order to attribute shoreline deformation to fault activity I identify shoreline elevation anomalies, where deformation exceeds a ± 0.3% window from normalized elevation values; this encompasses my conservative estimates of natural variability in the shoreline geomorphology and the error associated with the data collection. For each ramp-breaching fault style activity is concentrated near the fault linkage site. Even after a ramp is fully breached the severed fault tip temporarily retains some connectivity to the main fault segment. Severed fault tips along a mid-ramp breach tend to be more active than the severed fault tip at a footwall breach. Persistent fault activity along the entire severed fault tip is dependent on the position of the linkage. These results indicate that on the time scale of 104 years after linkage, severed fault tips persist as active structures and accommodate meaningful amounts of strain. / 1 / Christopher Samuel Young
