"Hidden Hills" is a secure, isolated enclave of 550 homes, with a long history of political and economic power wielded, in some cases, by families who have lived there for generations. This neighborhood serves as the bedroom for many of Portland's wealthy and well-known and has housed many of Oregon's-leading figures. It is faced with SB 917, a 1991 mandate to merge its only formal social institution, its 104-year-old school district, with one of two contiguous districts. Merger will not mean the immediate closure of the school, but will mean the loss of local administrative and political control and changes in the delivery of education and the arrangement of staff and students. The school will be run by another district in another community. This eighteen-month field study was undertaken in order to answer the questions: (a) How do neighborhood residents define this situation, and (b) What strategies will they devise to cope with the situation. I entered the community as a marginal participant and full observer. "Marginal" because, although I was the official recorder for both the school board's Consolidation Task Force (CTF) and High School Option Committee, I attended numerous other school and community meetings as a full spectator. I also conducted both formal and informal interviews and conversed casually with residents at every opportunity. Sources of secondary data were the 1990 Decennial Census: Multnomah County Elections Office: Oregon Department of Education; Oregon Historical Society Library; City of Portland Urban Services; Hidden Hills School District; and Multnomah County's Tax Supervising and Conservation Commission. The mandate to merge posed a threat to the neighborhood. The school is valued both for its educative and non-educative functions. It is a symbol of the neighborhood's integrity, part of which is its long history and body of tradition. It stands as testimony to the neighborhood's distinctiveness, which partially inheres in the institutionalization and the privatization of its school. It is the school that residents feel distinguishes this affluent neighborhood from other such neighborhoods. Its social cohesiveness and small-town atmosphere is perceived by residents as unique. There is a symbiosis between the school and the neighborhood that makes any threat to the school a threat to the neighborhood's identity. The rational response was mounted by the CTF, whose progress was halted at the point where neighborhood input was necessary but not forthcoming, due to what members perceived as denial. But residents were articulating a form of anticipatory grieving in the recurring reference to loss loss of identity, loss of local control, loss of the neighborhood school, and loss of academic excellence and small class-size. There was organized apathy among residents while they assimilated the fact that things this time were different. Initial impulses to make the old, formerly effective, forays "down to Salem" weren't working to gain exemption from the grip of the new law. It was time to form new lines of action based on a new definition of the situation. The CTF redefined the situation and did its work by identifying five options to consolidation. Residents were then brought together at neighborhood coffees where their subjective realities were negotiated within the constraints of the objective reality of the consolidation mandate. During these negotiations an intersubjective reality was realized where all residents, while having their own subjective meanings of the threat to the school and the neighborhood, were still able to articulate the objective fact that this was a threat to a core structure of meaning. Core values, beliefs, identity, and assumptions were brought into relief as residents re-defined the situation and discussed strategies to cope as a neighborhood, rather than as individuals. The CTF was given much-needed direction from neighbors.

This study investigates the strategies and resources a group of non-native English speakers with limited reading ability use to fulfill literacy functions work. The nineteen study subjects are employed as production workers in a large electronics manufacturing company. Using in-depth interview data, limited testing and document analysis, the study addresses three major research questions: 1) For what functions are reading and writing actually used in the workplace? What level of reading and writing do these functions assume? 2) How do these literacy functions relate to the rest of the work system? 3) How do limited readers fulfill these literacy functions? What kinds of individual literacy skills, social networks and alternative approaches do they use? How can findings be applied to workplace, ESL, job training, and employee communications? The findings show that the primary function of literacy in this workplace is to maintain process quality and flow. Secondary functions include maintenance of the social organization and the use of literacy for learning the job or learning English. The study finds that limited readers can accomplish literacy functions even if they cannot read documents connected to the function. They use extensive social networks as one strategy for accomplishing literacy functions. They also use job aids, watch processes being performed, or memorize processes. English verbal skills are necessary for many alternative strategies. The study illustrates systemic relationships among work process design, individual literacy skill, and alternative literacy strategies such as using help networks. The study also finds that participants take ESL class as a means to advance as well as to succeed on the current job. The study suggests that employers support ESL instruction as a long-term skill-improvement strategy, but look at redesigning work systems, job training, and employee communications to solve immediate performance problems with limited readers. The study recommends that workplace ESL instructors balance student and employee needs by using workplace materials as one part of a wider curriculum; it also suggests that ESL instructors may have an important role to play in the workplace by acting as performance consultants. going beyond the classroom to recommend changes in the entire work system as they affect English and literacy learning. Because of the small sample size, more research is needed.

Instrumental Neutron Activation Analysis (INAA) was used to identify geochemical groups in Boring Lava along the west side of the Tualatin Mountains, and in sediments of the Portland and Tualatin basins. Samples of Boring Lava were obtained from TriMet drill core collected during planning of the tunnel alignment for the Westside Light Rail line. Additional samples of Boring Lava were collected from outcrops along the west side of the Tualatin Mountains. Samples of sediment from the Tualatin and Portland basins were obtained from drill core collected during an Oregon Department of Geology and Mineral Industries (DOGAMI) Earthquake Hazards Mapping project. INAA of Boring Lava samples resulted in the identification of three geochemical groups. Additional data sets, including x-ray fluorescence geochemistry, magnetic polarity, and age dates, allowed for the distinction of three Boring Lava units. The Boring Lava of Barnes Road is a young, normal unit, the Boring Lava of Sylvan Hill is an older normal unit, and the Boring Lava of Cornell Mountain is the oldest, reversed unit. The surf ace distribution, identified using topography and outcrop geochemistry, is consistent with the subsurface distribution, identified using boring logs and core geochemistry. Volcanic vent locations are proposed at topographic highs within the identified surface distribution of the Boring Lava of Barnes Road. INAA of sediment samples resulted in the identification of seven groups: (1) Columbia River source sediments, (2) lower Troutdale Formation, (3) Reed Island ashes, (4) young Columbia River sediments, (5) highalumina basalt sediments, (6) episodic Cascadian volcanic sediments, and (7) Columbia River Basalt Group (CRBG) sediments. Only the CRBG sediments group was identified in the Tualatin basin, while all seven groups were identified in the Portland basin. This appears to demonstrate that the sediment packages in the two basins are different. Finally, each sediment group can be placed into one of three broad geochemical categories: Columbia River source sediments and lower Troutdale Formation represent a Columbia River or continental source; Reed Island ashes, young Columbia River sediments, high-alumina basalt sediments, and episodic Cascadian volcanic sediments represent a Cascadian or local source; and CRBG sediments represent residual soils or sediments overlying Columbia River basalt flows.

The United States' suburban landscape has historically been characterized by low-density residential development. This pattern was shaped by the abundance of developable land in nineteenth century America, and by the emergence of a suburban ideal which romanticized the concept of a spacious home set in a private, garden setting. For many homebuyers, the realization of the suburban ideal was made possible by continual improvements in intraurban transportation. The commuter rail, the electric streetcar, and ultimately the automobile increased the commuting range of inner-city workers, and contributed to the continual expansion of development on the periphery of cities. In recent years, economic and population pressures have contributed to accelerated housing costs in many metropolitan areas, necessitating a redefining of the traditional suburban ideal. Rising land costs have prompted developers to build single-family homes at increasingly higher densities. Developers now face the challenge of designing and implementing development strategies which maximize land use efficiency, and yet still retain some of the "garden setting" ambiance of the traditional suburban ideal. This study traces the historical evolution of residential densities in Washington County, through review of 2235 Washington County plat maps dating from 1870 to 1992. The data reveals a slow growth, low-density development prior to World War II, and a high-growth and increasingly higher-density pattern of development in the post-World War II period. Since 1980, high-density suburban developments have become an increasingly common feature of the Washington County landscape. Examination of the spatial distribution of these subdivisions suggests a strong correlation between high-density development and land scarcity. Comparison of the different types of high-density subdivisions found in Washington County reveals how common-space developments allow for more effective integration with the natural environment. The future of subdivision development in Washington County, hinges upon the results of Metro's Region 2040 study. The Region 2040 study will ultimately recommend the extent that the urban growth boundary should be expanded, and thus will directly affect the availability of developable land The amount, type, ownership, and zoning of these "urban reserves" will be important considerations for future subdivision development in Washington County.

For about the first fifteen years after its commercial introduction motion picture entertainment throughout the United States was supported almost entirely by the mass of urban industrial workers, immigrants and their families. Beginning a few years before 1910 motion pictures began acquiring regular support from a limited element of the more affluent citizens until by the end of 1916 they constituted motion pictures' primary audience. This paper examines the audience development and conversion as it occurred in the downtown theaters of Portland, Oregon. Motion pictures were shown to two diverse audiences in Portland during the 1890s, regularly on a mass level to the lower income strata and sporadically to regular stage theater audiences. Their expectations differed greatly. Urban workers craved entertainment for the sake of diversion while middle and upper class audiences required responsibility and purpose in their entertainments. After the turn of the century when big time vaudeville established itself in Portland films were supported almost entirely by the lower class element in arcades and vaudeville theaters. Motion pictures in these venues catered to their audiences' tastes. During the 4-5 year period after nickelodeons developed in 1906 a small number of Portland's middle class became regular patrons, due partially to national imposition of licensing and establishment of a censorship board fostering a more respectable image. After 1910, when national support for motion pictures had been proven permanent and unsatisfied, large movie palaces emerged in Portland. These theaters and their amenities created atmospheres consistent with those of stage theaters, providing comfortable and familiar surroundings for middle class audiences. Industrywide developments such as increased story length, better quality productions and evidence of social responsibility enhanced the ease of middle class transition from the stage theater to the movie theater.

Much advice has been published in the last 40 years that has attempted to aid speech-language pathologists in choosing language assessment tools (e.g., Danwitz, 1981 & Darley, 1979 ). Questions have arisen about what tests are actually being used in public schools and the reasons for those tests being used over other tests. The data bank of information is minimal in this area as only one study has appeared in the literature in which Wilson, Blackmon, Hall, & Elcholtz, (1991), conducted a State survey of currently used language assessment instruments. The primary research question to be answered was: What methods of language assessment are being used in Oregon? Secondary questions to be answered were: (a) What factors influence the selection and use of the chosen procedures?, (b) What are the dates of development of the tests used most frequently, (c) By what means do the public school clinicians keep themselves current with new trends and information in the field? There were 567 questionnaires mailed out to Oregon Speech-Language Pathologists who worked in the public school setting and served children 4-9 years of age. Of the 297 respondees, only 4 reported not using any formal instruments for language assessment. Results show 9 main standardized tests were used for measuring expressive language by the majority of the respondents. Listed in order of frequency of use, they are: TOLD, EOWPVT, WORD test, CELF, LPT, SPELT, ASSET, TOPS, and the PLS. For receptive language, also in order of frequency of use, the 1 O main tests were as follows: PPVT, TOLD, CELF, TACL, ASSET, BOEHM, PLS, ROWPVT, BRACKEN, and the LPT. Factors that influenced the selection and use of specific tests included: personal experience; ease of administration; time restraints; budgets and availability of tests and district protocols for assessments. Dates of publication, new and revisions, for both the expressive and receptive tests used ranged from 1983 - 1990. At the time of this survey, the main ways that clinicians were keeping themselves current for new tests on the market were word of mouth from associates, inservices on new tests, and reading new information in journals.

This study examines the natural background concentrations of arsenic in the soils of southwest Oregon, using new samples in addition to data collected from previous theses (Khandoker, 1997 and Douglas, 1999). The original 213 samples were run by ICP-AES with a reporting limit of 20 ppm, and only three samples had detected values. The original samples were tested again (2013) at a lower reporting limit of 0.2 ppm by ICP-MS, as were 42 new samples (2013), to better ascertain the natural levels of arsenic in undisturbed soils. The aim is to add to the existing DEQ data set, which has been used to establish new regulatory levels based on natural levels in the environment that are both safer and more economically viable than the former risk-based remediation levels (DEQ, 2013). The maximum and mean concentrations, respectively, for each province (with high formation map unit) are 85.4 and 21.99 ppm for South Willamette Valley (Tfee), 45.4 and 5.42 ppm for the Klamath Mountains (Jub), 11.9 and 2.76 ppm for the Cascade Range (Tbaa), 10.6 and 5.15 ppm for the Coast Range (Ty), 2.32 and 1.29 ppm for the Basin and Range (Qba) and 1.5 and 1.20 ppm for the High Lava Plains (Tmv). In addition, the distribution and variance of arsenic in the A and B soil horizons is assessed in this study by comparing deviation at a single site, and also by comparing A and B horizons of 119 PSU sites. One of 18 new sites sampled for this study (distinguished with the HH prefix), site HH11, was randomly chosen to evaluate differences at a single location. Site HH11 is an Inceptisol soil above volcanic rock (KJdv map unit) located at 275 meters elevation in Douglas County within the Klamath province. Five samples were taken from the A and from the B horizons at site HH11. The means and standard deviations were 3.74 ± 0.44 for the A horizon and 4.53 ± 0.39 for the B horizon. The consistency and low deviation within each horizon indicate that a single sample within a horizon is a good representative of that horizon and supports the field methodology used in this study of taking only one sample in the A horizon and one sample in the B horizon. Wilcoxon Rank-Sum test determined that A and B horizons for the 119 sites that had data for both the A and B horizons were not statistically different (p-value 0.76). Arsenic concentration is not associated with a particular horizon for these sites. However, differentiation between soil horizons increases with age (Birkeland, 1999), as does accumulation of the iron oxides and sulfide minerals on clay surfaces (McLaren et al., 2006) which concentrate in the B horizon. These associations warrant further study to see how they relate to arsenic level, soil development and age in Oregon soils. Lastly, this study statistically examines six potentially important environmental predictors of naturally occurring arsenic in southwestern Oregon: site elevation, geomorphic province, mapped rock type and age, and sample soil order and color (redness). A Classification and Regression Tree Model (CART) determined soil order, elevation and rock type to be of significant importance in determining arsenic concentrations in the natural environment. According to the regression tree, arsenic concentrations are greater within Alfisol and Ultisol/Alfisol and Vertisol soil orders, at lower elevations below 1,207 meters, and within soils from sedimentary, mixed volcanic/sedimentary and unconsolidated rock types.

Research on the education of Vietnamese-Americans is very limited, and mainstream media continue to project Vietnamese students either as high achievers or gang affiliated (Castro, 1983; Davis & McDaid, 1992). This kind of projection can mask the real issues that Vietnamese students are facing. Based on Cummins' (1979) Contextual Interaction Theory, this study examined the views of Vietnamese-American high school students in Oregon regarding their schooling under four major areas: Community Background Factors, Educational Input Factors, Instructional Treatment, and Student Input Factors. In particular, this study examined factors, within the above four areas, pertaining to the schooling of Vietnamese-American high school students such as parental concerns, peer relationships, language use in the classroom, ESL learning, subject areas, teacher support, first language usage, discipline issues, home/school communication, teacher knowledge about culture, extracurricular activity, drug/alcohol issues, gang affiliation, dropping out, student effort in learning, homework, career planning, and future concerns. A survey of 145 subjects was conducted in the Portland and surrounding high schools. The study was supplemented by two interviews of two unique students: a high-achiever and a high-risk case to illuminate the real life and school experiences they encountered in their schooling. The interviews added a holistic dimension to this study. The survey data were analyzed descriptively, statistically, and inferentially to provide answers for the research questions. The overall conclusion was Vietnamese-American high school students in this sample came from large families with strong family support and value for education. They brought with them a strong motivation for learning. They were committed to school work and put much effort in learning. They reported doing well in mathematics and science. They reported difficulties in English language comprehension, but only one third of them perceived ESL as a strong treatment. Very few were participating in extracurricular activities. Their relationships with American peers were poor. They perceived a good level of staff welcome and support but were not sure about the staffs understanding of their culture. These students showed a respect for school rules, but reported little school/home communication. Many worried about their future. Briefly, their perceptions regarding educational input factors and instructional programs were not as strong as community background factors and students' contributions.

The Calapooia River, a major tributary of the Willamette River in western Oregon, is a watershed typical of many found in the Willamette Basin. Public and private forested lands occur in the steep Upper Zone of the watershed, mixed forest and agriculture lands are found in the Middle Zone, and the Lower Zone of the watershed is comprised primarily of grass seed agriculture on relatively flat topography with poorly drained soils. High levels of dissolved nitrogen (DN) have been identified as a water-quality concern within the Calapooia River. To gain a better understanding of the relationship between landuse/landcover (LULC), soil drainage, and DN dynamics within the watershed on a seasonal basis, we selected 44 sub-basins ranging in size between 3 and 33 km² for monthly synoptic surface water-quality sampling from October 2003 through September 2004. We selected an additional 31 sample locations along the length of the Calapooia River to determine relative influence of the 44 sub-basins on DN concentrations in the river. T-tests were used to analyze differences between zones (Upper, Middle and Lower) and regression analysis was used to determine relationships between DN and LULC or soil drainage class. The agriculture-dominated sub-basins had significantly higher (< 0.05) DN concentrations than the predominantly forested sub-basins. Winter concentrations of nitrate-N were 43 times higher in agriculturally dominated sub-basins than in forested sub-basins, whereas in the spring, the difference was only 7-fold. High DN concentrations associated with the predominantly agriculture sub-basins were substantially reduced once they mixed with water in the Calapooia River, highlighting the likelihood that water draining the relatively nutrient-poor, forested sub-basins from the Upper Zone of the watershed, was diluting DN-rich water from the agriculture sub-basins. Relationships between DN and agriculture, woody vegetation or poorly drained soils were moderate to strong (0.50 < R² > 0.85) during the winter, spring and summer seasons. Results indicated an exponential increase in DN concentration when proportion agriculture or poorly drained soils increased, whereas an increase in woody vegetation was related to an exponential decrease in DN concentration. The high variability in DN concentration in the agriculture-dominated sub-basins suggests factors in addition to LULC and poorly drained soils influence DN in surface water. Seasonal relationships were developed between DN and proportion of poorly drained soils, agriculture, and woody vegetation at differing scales (10 m, 20 m, 30 m, 60 m, 90 m, 150 m, 300 m, and entire sub-basin), which we defined as Influence Zones (IZs), surrounding the stream network. Correlations between DN and proportion LULC or poorly drained soil at each IZ were analyzed for significant differences (p-value < 0.05) using the Hotelling-Williams test. Our results show strong seasonal correlations (r > 0.80) between DN and proportion of woody vegetation or agriculture, and moderate-to-strong seasonal correlations (r > 0.60) between DN and proportion of sub-basins with poorly drained soils. Altering scale of analysis significantly changed correlations between LULC and DN, with IZs < 150 m generally having higher correlations than the sub-basin level. In contrast, DN correlations with poorly drained soil were generally higher at the sub-basin scale than the 60- through 10-m IZs during winter and spring. These results indicate that scale of analysis is an important factor when determining relationships between DN concentration and proportion LULC or poorly drained soils. Furthermore, seasonal shifts in significant differences among IZs for correlations between LULC and DN suggest land management proximity and its influence on DN concentration changes temporally. DN relationships with poorly drained soil suggest that during winter and spring, when rainfall is highest, sub-basin scale soil drainage properties have a greater influence on DN than soil properties within IZs in close proximity to the stream network. / Graduation date: 2006

Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly different geochemical reservoirs over time. The High Lava Plains (HLP) and Northwestern Basin and Range (NWBR) in central and eastern Oregon provide an excellent example of intraplate volcanism where we can examine the beginnings of segregation of a relatively young, recently accreted crust. The origins of continental magmatism and its relationship to plate tectonics, especially away from the continental margins, are only slowly becoming revealed. The western United States is the most volcanically active part of North America during Cenozoic time, and this activity includes the enigmatic volcanism of the HLP and NWBR. Rhyolitic volcanism in the HLP and NWBR is age-progressive but in a direction that is nearly perpendicular to North American Plate motion. Despite being erupted through a similar crust and with a similar composition of mafic input, the HLP province is strongly bimodal (basalt-rhyolite) while the NWBR province exhibits a continuum of compositions. High silica rhyolites are commonplace in the HLP, with approximately a 1:1 ratio of rhyolite to basalt, even though the crust is comprised of mafic accreted terranes. Asthenospheric flow, mantle melting and crustal extension coupled with southwesterly North American plate motion explain the age-progressive volcanism of the HLP and NWBR. Differential asthenopheric counterflow and mantle upwelling created by the down-going Cascadia slab, coupled with transtensional stresses related to the rotation of the North American plate and Basin and Range extension, decreasing to the north, can produce the observed variations in rhyolite compositions and volumes in the two adjacent provinces. These differences are caused by fundamentally different petrogenetic processes that take place in the crust. In the HLP, an increase in mantle-derived magma flux into the lower crust has created low silica rhyolite via partial melt that separated, coalesced and rose buoyantly. This low silica rhyolite may erupt, solidify in the upper crust, or differentiate by fractional crystallization to produce high-iron, high-silica rhyolite containing an anhydrous phase assemblage. In the NWBR, a smaller flux of basaltic magma, coupled with greater transtension resulted in small crustal processing zones where fractional crystallization coupled with magma mixing and recharge created a wide range of compositions. Partial melting to form rhyolites was limited. These rhyolites have lower iron, and hydrous phases (biotite, amphibole) are common. These processes modify the crust in different ways, leaving a stratified crust in the HLP but a less modified crust in the NWBR. Recent geophysical and isotopic studies bear out these differences and allow for a unified, internally consistent model for both provinces, one that relies only on partial melt generation driven by current plate movements and do not require a mantle plume contribution. The bimodal volcanism of the HLP is a direct consequence of the processes that cause the gravitational differentiation of the continental crust into upper and lower units. The model for the HLP is generally applicable to other localities that have predominantly mafic crust and a similar balance of crustal transtension and mantle-derived basaltic flux. One such place is Iceland, which has strongly bimodal (basalt – rhyolite) volcanism. In areas where silicic crust has become substantially more mafic due to a high flux of intraplated basalts, such as in the bimodal Snake River Plain, the model is also applicable. / Graduation date: 2012 / In order for the .age files to run, the add-in called ArArCalc for Excel (version 200 or 2003) must be installed.
