Geochemistry of the Boring Lava along the West Side of the Tualatin Mountains and of Sediments from Drill Holes in the Portland and Tualatin Basins, Portland, OregonBarnes, Michelle Lynn 06 October 1995 (has links)
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.

Parental Perceptions of the Efficacy of Clinical Intervention for Speech-Language Disorders at Portland State University's Speech and Language ClinicAnderson, Deborah Ellen 06 June 1996 (has links)
The purpose of this study was to investigate the survey as a method of assessing client satisfaction with clinical services and to then assess parental satisfaction of clinical services at Portland State University's language clinic using the survey method. The survey asked questions regarding the parents' perceived benefits from the clinic, their perception of the skills of the clinicians who served their children, and the parents' perception of the clinical atmosphere. Eighty-five Consumer Satisfaction Surveys were mailed to 81 parents of children receiving services at Portland State University Speech-Language Clinic between the years 1987 and 1994. Eleven surveys were returned, all containing a signed consent letter, representing a 13% rate. Determining the cause behind the poor response rate for this particular survey was not difficult. No surveys were returned from the years 1987 through 1989. The highest percentage of return was from the year 1994 (38% ), indicating that higher response rates were achieved if the client was polled within 1 year of using clinical services. To further substantiate this conclusion, two of the parents contacted by telephone refused to participate in the survey, and gave length of time as the reason behind their refusal. The overall response to the survey was positive, indicating a high rate of satisfaction among the survey respondents with the services provided at the Portland State University Speech-Language clinic.

Motion Picture Exhibition and the Development of a Middle-class Clientele: Portland, Oregon, 1894-1915Labosier, James Bruce 28 February 1995 (has links)
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.

Respect and Reuse: Sustainable Preservation in Portland, Oregon / Sustainable Preservation in Portland, OregonJohnson, Bethany N., 1983- 06 1900 (has links)
xvi, 109 p. : ill., maps. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number. / The 'culture of sustainability' is rapidly developing across the United States and
the globe. Prompted by economic and environmental crisis, the need to understand and
implement sustainable practices has become the paramount objective of the building
industry. Utilization of historic preservation as a response to sustainable development is
an important aspect of the building profession not yet fully understood, though its roots
are found in the "new life for old buildings" movement of the 1970s. This lack of
understanding is, in part, due to limited research addressing the conservation and
sustainability of the existing building stock within the United States. This thesis will
provide case study research on successful sustainable preservation strategies that have
been filtered through the National Register of Historic Places and the LEED Green
Building Rating System, helping to define the opportunities for beneficial interchange. / Committee in Charge:

Companhia Brasileira de Cimento Portland Perus : contribuição para uma história da indústria pioneira do ramo no Brasil (1926-1987) /Siqueira, Elcio. January 2001 (has links)
Orientador: Sonia Irene Silva do Carmo / Banca: Benedito de Moraes Neto / Banca: Yvone Dias Avelino / Resumo: Pioneira da indústria cimenteira no país, a companhia Brasileira de Cimento Portland Perus (CBCPP) foi inaugurada em 1926. Em 1951, seu controle acionário passou para o Grupo Abdalla que instalou um forno que expandiu em 60 % a capacidade produtiva sem qualquer ampliação na infra-estrutura de alimentação (dimensionada para os três fornos originais), procedimento afinado com a expansão da demanda no Brasil do pós-guerra, mas que submetia o maquinário a níveis destrutivos de esforços. Era natural, portanto, que, as greves operárias pusessem em xeque a forma de gestão da empresa, com os trabalhadores implementando um plano de medidas técnicas alternativas em 1960-61 que criou uma autêntica situação de dualidade de poder dentro da companhia. Em 1962, uma greve iniciada em solidariedade a trabalhadores de outras firmas de Abdalla derivou para uma luta direta pela desapropriação da Perus com vistas a implantar uma co-gestão Estado/Operários. A paralisação foi derrotada, com profundas seqüelas no meio popular, parcialmente sanadas com a reintegração dos operários estáveis em 1969. A esta altura, porém, o futuro da fábrica já estava comprometido pelo desgaste dos equipamentos, quadro que o confisco federal em 1973 não reverteu. A empresa voltaria para a iniciativa privada em 1980 já praticamente liquidada, e funcionaria de forma agonizante até o fechamento em 1987. / Mestre

Local Approaches to Regional Problems: Suburban Government Responses to Portland's Regional Housing CrisisDeppa, Emma 14 July 2016 (has links)
The Portland metropolitan region has seen unprecedented growth in the last three decades, resulting in both economic expansion and considerable gentrification. While lauded for its commitment to sustainability and a "smart development" ethos, many questions remain for the city with respect to the needs of displaced residents and a burgeoning population of young professionals. This study examines how various levels of government implement growth management policies to accommodate these demographic changes, and aims to assess whether and how the consequences of growth, especially gentrification and displacement, are meaningfully addressed. Qualitative interviews were conducted with staff members and elected officials from city, county, and regional government structures across the Portland metropolitan area to investigate the "regional housing crisis." Inductive analysis of these data considers the implications of Portland's layered government structure for making equitable growth-related decisions.
Participants expressed a mismatch in what was expected of them--both from higher levels of government and their constituents--and their perceived capacity to do so. While government officials advocate the need for new development of affordable housing units, they see themselves as limited by a series of technical barriers in the stratified planning process, as well as an unequal distribution of influential power in public involvement processes. Findings are synthesized to offer policy recommendations and consider alternative government responses to public housing issues.

A history of the Portland waterfront between southwest Clay and Washington streets, its land use and legal problemsCarter, Jeffrey G. 01 January 1981 (has links)
Between 1845 and 1980 the Portland waterfront between southwest Washington and Clay Streets, east of Front Street, metamorphosed from wilderness to trade center, to highway, to inner-city vacant lot. No place in Portland has more graphically illustrated the rapidly changing forces of the modern age in which the city has grown.
For much of its history this stretch of waterfront was mired in law suits. The struggles centered on public versus private ownership. Originally dedicated as public property, but left unimproved by the city, the waterfront was usurped by private investors. Eventually, private owners allowed their property to decay prompting the public to encourage improvements. The legal battles even became reversed as private investors sought to force the sale of the waterfront to the city.
Through all the confusion of legal battles this stretch of waterfront played a central role in the development and identity of Portland. It has finally become, undisputed public territory. The tension and greed of private investment have been replaced by the lack of municipal funds for aesthetic improvement and have left this stretch of land, a potentially fine and important urban park, a vacant lot.

Postfledging Survival and Habitat Use of Spotted Towhees (Pipilo maculatus) in an Urban ParkShipley, Amy Ann 01 January 2011 (has links)
Habitat fragmentation, and the resulting increase in edge habitat, has important effects on birds, including the increased probability of nest predation, changes in habitat structure, and the increased presence of non-native plant species. It is critical to understand the effects of fragmentation at all stages of the avian life cycle, including the often overlooked postfledging period. Because much of juvenile mortality occurs during the immediate postfledging period, and juvenile mortality contributes substantially to population dynamics, it is necessary to understand if fledgling survival is reduced in edge habitats and if fledglings' survival is influenced by their habitat use. During 2008 and 2009 I radio-tracked 52 fledgling Spotted Towhees (Pipilo maculatus) during the 30-day postfledging period in a 24-ha urban park near Portland, Oregon. Thirty-six fledglings (69%) survived the 27-day tracking period (an estimated 62.1% survived the entire 30-day postfledging period). At least 9 of 16 predation events were attributable to domestic cats (Felis domesticus) or Western Screech-owls (Megascops kennicottii). Although fledglings were more likely to be found near edges than the park interior, fledglings located closer to park edges had a higher probability of dying. However, I found that towhee nests were more likely to be found near edges, nests near edges produced more fledglings, and nestlings near edges were heavier. I used a STELLA-based stochastic model of nest success and fledgling survival to show that the benefits initially gained by nesting near edges were reversed during the postfledging period. The number of fledglings per nest that survived to the end of the 30-day postfledging period was significantly lower near edges than in the park interior. This apparent preference for nesting near edges, paired with higher fledgling mortality near edges, is consistent with the idea that edges are ecological traps. Fledgling habitat was significantly more structurally dense and had a greater abundance of non-native plant species, particularly Himalayan Blackberry (Rubus armeniacus), than nest habitat. Towhees avoided English Ivy (Hedera helix) for both nesting and care of fledglings. However, fledgling survival was not related to vegetation characteristics, which suggests that increased fledgling mortality near edges was a direct result of increased predator abundance or predation near edges, and was not an artifact of changes in habitat near edges. My results help to establish that fledgling survival and the unique habitat requirements of fledglings should be considered along with nest success and nest habitat when examining the effects of habitat fragmentation on bird populations. More broadly, this study has important implications for conservation, as it exemplifies how phenomena such as ecological traps created by anthropogenic changes in the environment can be overlooked if only one life history stage is studied.

Public Space and Urban Life: A Spatial Ethnography of a Portland PlazaJohnston, Katrina Leigh 01 January 2013 (has links)
The Urban Center Plaza at Portland State University is a high profile place situated in downtown Portland, Oregon. In some ways it is the ideal university plaza providing space for eating, conversing, or limited recreational activity. It is a place that has been studied before, but not in a more in-depth method incorporating quantitative and qualitative analyses. It is also a place that has gone through several stages of development and is the target of many opinions based on casual observations, at times due to these changes. This thesis focuses on an ethnography of place in this particular plaza in an effort to more thoroughly analyze how people use the space and how it came together to become the plaza known by Portlanders today. This is done through the use of random video observations, direct observations, and in-depth interviews with those who were involved in the creation of the plaza. Analysis of the video recordings includes pedestrian counts, behavioral maps, and common routes taken through the plaza. Direct observations provide more insight into the day-to-day activities of the plaza and the phenomenological perspective of the design elements. Interviews allow for a more complete timeline of events in order to assess the plaza properly. By combining these methods based on other plaza-based ethnographies, it is concluded that the plaza is a well-used and successful space and even suggest possible areas of improvement. Methods are also assessed for future use on other city parks and plazas, possibly in a comparative context.

The Effects of Income Inequality on Racial Residential Segregation in the Portland Metropolitan AreaAidinezhad, Katayoun 25 November 1985 (has links)
Changes in the patterns of income and residential segregation were examined in the Portland Metropolitan Area. The 1970 and 1980 Census of Population and Housing were used in calculating the indexes of dissimilarity between black and white populations. The data indicated a significant decrease in the residential segregation of blacks in suburban areas between 1970 and 1980. The central city area still remained highly segregated with a segregation index of 69.5.
Taeuber's index of dissimilarity was used in calculating the unevenness in the distribution of income between blacks and whites. Suburbia showed a significant decrease in income segregation compared to the central city area. Overall, both residential and income segregation were dropping at a much faster rate in the suburban areas than the central city areas.
To examine the effects of socio-economic status on residential segregation, a sample of 138 blacks was drawn from the population of higher status blacks in the city of Portland. Residential choices of the influential blacks were examined to determine whether or not their influential status was accompanied by a tendency toward greater integration as opposed to greater segregation. The 1980 Census Tract Street Index was used in this analysis. The data show that despite the improvement in socio-economic status, a majority of these blacks still lived in the "ghetto" area (59%) and only 14% lived in suburbia. Therefore, the data show no significant relationship between the gains in the status and the tendency toward more integration. This tendency bears directly upon the issue of voluntary segregation.
The data shows strong support for hypothesis two holding that change in income inequality results in change in residential segregation. That is, if we reduce the income differentials between black and white populations, racial residential segregation will be minimized.
