Between 15 March and 29 July 1998 we quantified aggressive movements (AMs) in a breeding colony of 44 adult magellanic penguins (MPs) during their nesting season at San Francisco Zoo (SFZ). We sampled their behavior for a total of 149.5 hrs in 46 sessions of 195 min each, all starting at 0945 hrs and stopping at 1300 hrs. We recognized 4 types of AMs, of which 2 (eye-pointing and charging) were threat signals, I (bill-fencing) was a ritualized contest of strength and agility, and I (biting) was physical attack. MPs only performed AMs within 2-3 m of nest entrances. Males performed 83% of all AMs, females 17%. The eye-pointing threat signal accounted for 92% of all AMs, and the 3 non-attack AMs combined accounted for 99% of all AMs; only I% involved physical assault. Both sexes performed eye-pointing and bill-fencing, but only males charged or bit their adversaries.

Population abundances of English sole within the San Francisco Bay from 1973 to 1981 showed a significant positive correlation with Delta outflows, and a significant negative correlation with salinity. Temperature in the bay and ocean upwelling showed no correlation with English sole abundance in the Bay. Because of the positive correlation between the abundance of English sole in the South San Francisco Bay and Delta outflow, this study suggests that any factor resulting in a reduction in outflow may reduce the abundance of English sole in the sample area.

The state and federally endangered California clapper rail ( Rallus longirostris obsoletus) has declined in abundance and been reduced in range and now occupies fragmented intertidal saltmarsh only within San Francisco Bay. Historically extensive salt marsh habitats existed in San Francisco Bay and today, remnants are largely restricted to the water's edge with dikes and levees separating marshland from modified habitats unsuitable for clapper rails. Clapper rail population abundance has roughly tracked a series of positive and negative impacts including market hunting at the turn of the 20th century, widespread habitat reduction and fragmentation, and invasive species introduction and eradication programs. Despite these changes, rail populations have been subject to the ebb and flow of the tides, which regularly inundate salt marsh habitats. The influence that tides have on vertebrate species living in intertidal saltmarsh should be substantial, but the relationship between tide and California clapper rails is poorly understood. This research identified important ways in which tides influenced demographic processes, space use, and resource selection in California clapper rails. Tidal inundation in San Francisco Bay saltmarshes creates zonation in plant communities, typically with tall monocots in the low marsh (Spartina sp.), short pickleweed (Sarcocornia pacifica) in mid-elevation ranges, and gumplant (Grindela humilis) in the high marsh. Invasive Spartina (Spartina foliosa x alterniflora ) grows taller and thicker than native Pacific cordgrass ( Spartina foliosa). Invasive Spartina also grows lower onto mudflats, further up into pickleweed areas, and provided both nesting habitat and tidal refuge for clapper rails. In Chapter 1, I examined survival rates of California clapper rails. Specifically, I investigated whether seasonal patterns observed in the early 1990s were still evident and assessed the influence that Invasive Spartina and the degree of tidal inundation on weekly survival rates in four South San Francisco Bay salt marshes. Between January 2007 and March 2010, California clapper rail annual survival was 73% greater in Spartina-dominated marshes (Ŝ = 0.482) than in a control marsh dominated by native vegetation (Ŝ = 0.278). Lower survival also occurred during periods when tide height was greatest and during the winter. Survival patterns were consistent with Invasive Spartina providing increased refuge cover from predators during tidal extremes which flood native vegetation, particularly during the winter when the vegetation senesces. Tide heights also strongly influenced selection for artificial habitats provided adjacent to one marsh during the winters of 2010-2011 and 2011-2012. Ten floating islands equipped with canopies providing cover were monitored using time-lapse cameras for evidence of clapper rail use. Clapper rails regularly used artificial islands once tides reached heights equal to the average surface elevation of the marsh. When tides had inundated the marsh plan, observed use of the artificial islands was more than 300 times expected use based on the surface area provided. Probability of use varied among the islands and low levels of use were observed at night. Endemic saltmarsh species are increasingly at risk from habitat change resulting from sea-level rise and development of adjacent uplands. Escape cover during tidal inundation may therefore need to be supplemented if species are to survive. I developed a new method to estimate space use accounting for individual movement phases within non-stationary relocation datasets using simulated radio-telemetry data. To define movement phases I used a nonparametric, multivariate test to detect change points in the mean or variance of a sequence of x,y coordinates. Once all phases (change points) were identified, Gaussian kernel density analysis was used to estimate space use during each phase, which I termed change-point utilization distributions (CPUDs). One advantage of this technique is that the location of change points can subsequently be tested for relationships with conditions that might trigger a change in how individuals use space. Change points in clapper rail movement were associated with a variety of environmental and biotic variables including high tides, nesting activity, intrusion by neighboring clapper rails, and transient movements outside the home range. Change points occurred more than twice as frequently during the highest observed tides relative to all other tide heights. Another use of CPUDs is that space use patterns of adjacent individuals can be evaluated for joint overlap only during specific time periods when overlap occurs. I used CPUDs developed for California clapper rails and identified the point within overlapping space-use estimates where each individual had priority access to the resources within its utilization distribution (i.e. the lowest kernel density isopleth that was common to two overlapping individuals). This provided an estimate of the spatial region at which individuals exhibited territoriality. During the breeding season, space use distributions overlapped less and average territory size increased relative to the non-breeding seasons. Population density implied by these territory sizes (1.38 birds/ha) is comparable to density estimates during the 1970s and 1980s. Together these findings show the great degree to which clapper rail behavior and demography can be influenced by the tides that populations experience. It is my hope that conservation efforts for this species, particularly in the arena of habitat restoration may benefit from this research.

The purpose of this study was to examine the factors important to the establishment of a Chinese language immersion program in San Francisco, parent motivations and attitudes toward the program, and the impact of the program on student achievement. Descriptive data collected on the 1st and 2nd year of program implementation included summaries of interviews with school personnel, information from documents of the San Francisco Unified School District, tabulations of parent questionnaire responses, and scores from a kindergarten skills inventory and Cantonese Language Skills Test. The comparative portion of the study included an analysis of CTBS-S scores of the program participants and a comparable group of students. The District implemented the Chinese immersion program because of the prior success of a Spanish immersion program, and the influence of a group of parents who were highly interested, organized and motivated. The Chinese immersion program is basically patterned after the Canadian early total immersion model. Both programs were initiated by parents. The major differences from the Canadian model were the ethnic and linguistic composition of students and the timing of introduction of English instruction. Parents enrolled their children in the Chinese immersion program because of a desire for their children to better understand and respect their own and others' cultural and linguistic heritages. Parents were highly satisfied with all aspects of the program. Program participants acquired Cantonese proficiency and literacy skills while developing and maintaining English academic skills. Further research is necessary to address the long term effects of the Chinese immersion program on participants' English academic skills, English language development, Chinese fluency and literacy, and their appreciation of multiculturalism and multilingualism.

Vigilantism has a long history in the United States stretching back to the Regulator movement in South Carolina in 1767. These extralegal movements are distinguished from spontaneous and ephemeral mob activity by their regular organization and limited life-span. The San Francisco Committee of Vigilance of 1856 was the largest vigilante movement in American history. After a summer of vigilantism that included four hangings, the committee turned to politics and formed the People’s Party which dominated San Francisco's city government for the next decade. The 1856 committee is generally considered the great exemplar of American vigilantism and has received considerable attention from scholars. San Francisco’s 1856 vigilance committee regarded itself as a reorganization of that city's 1851 Committee of Vigilance. Like its more illustrious offspring, the 1851 committee hanged four men and banished many others. The vigilantes of 1851 did not, however, form a political party. Because of this some scholars have considered the work of the 1851 committee to be incomplete and have deemed it less worthy of attention than the committee of 1856. But in attempting to understand the intellectual grounding of San Francisco's vigilantes, this view is incorrect. The vigilantes in 1856 felt they were carrying on the work of the 1851 committee. Thus, to comprehend the events of 1856 it is necessary to understand the inspiration for the 1851 vigilance committee. The key to vigilantism in San Francisco lies in 1851. An understanding of the spirit which animates vigilantism is valuable because of what it reveals about American concepts of self-government. Vigilantes conceive of their their authority as springing from the same source as does that of the government: the people. San Francisco provides an extraordinary case for the study of notions about popular sovereignty in antebellum America. In order to make sense of what happened in San Francisco in 1851 this thesis first analyzes the political thought and philosophy that had developed in America to that time. It also examines the changing social ethos that came to emphasize equality. The two vigilance committees of San Francisco were a consummation of the political and social developments of antebellum America. I have relied on the extensive secondary literature for my interpretation. San Francisco in 1851 was in the midst of a singular episode in American history: the gold rush. The promise of riches made California the reification of the ideals of equality and opportunity that matured during the antebellum era. For the exploration of California and San Francisco I have used secondary sources and some primary sources, especially the Alta California, one of San Francisco’s newspapers. This reliance on the Alta was in part due to its availability. The attitudes toward vigilantism expressed by the 표L후르 were similar to other California newspapers. All of them supported the vigilantes in 1851. The episode of vigilantism in 1851 was a formative experience for the city of San Francisco. It served as an example of popular action and helped to define the limits of such action for the city's residents. The relationship between popular action and government was illuminated in San Francisco. Because of the way in which the people were endowed with power, they could create government and later defy that same government without destroying their creation.

This case study examined the San Francisco Mayoral Office's public relations management of the issuance of same-sex marriage licenses. The research was conductedas a case-study, integrating a comprehensive literature review and semi-structured interviews. Analysis of the results suggested that the Mayoral Office's campaign was successful in meeting its goal of marrying same-sex couples; the Office was somewhat effective in getting its primary messages reported by the print media, and the Office utilized innovative strategies to reach its key publics through the use of diverse spokespersons and a humanizing focus. Five major implications emerged from the study. First, crisis planning is essential to the effective management of crisis situations. Second, humanizing controversial messages to target audiences can be very effective. Third, providing media training to spokespersons can improve the organization's overall message. Fourth, segmenting key messages within the target audience is fundamental. Fifth, spokespersons' roles can have a significant impact on the public's perception of an organization's management of a crisis situation.

In a setting of increased movement, communication, and flows across space, commodity chain networks bring valued cultural commodities to transnational communities. This research examines the networks bringing foreign cuisine ingredients to Peruvian transnational communities in San Francisco, California. It seeks to answer three inter-related questions: 1) What are the origins and transportation networks bringing Peruvian food items to San Francisco; 2) Who controls and benefits from the movement of this food and resulting capital; and 3) How do networks vary for different classes of end consumers? Chefs of ten Peruvian restaurants and ten Peruvian migrants in the San Francisco area are interviewed to determine primary imported Peruvian food items and their cultural value. Interviews with representatives of major importing companies as well as searches of import/export databases are used to trace network flows. Flow maps follow the food items from the point of origin to the point of consumption and visually demonstrate the flow of resulting capital. Additionally, network maps are divided into three categories determined by end consumer: expensive restaurant, moderate restaurant, and home cooking. Maps are analyzed for differences between these categories. Finally, a narrative analysis discusses the role of migrants' cultural eating habits in San Francisco and its connection to transnational commodity networks. The research offers commentary on the role of food as a cultural marker for Peruvian transnationals and on the relations of power within the commodity network. This research unites economy and culture at the local and global scales while showing how “things” are imbued with cultural meaning during the processes of production to consumption on a transnational network.

This research study addresses the problem of unmet facilities needs in the California Community College (CCC) system with a case study analysis of two major campus construction projects within the City College of San Francisco system (CCSF). Specifically, this study is intended to provide insight into the difficulties facing CCC administrators regarding unmet facilities needs within their campuses, and the overall processes and challenges involved in constructing the 21 st century CCC campus. Interviews with the campus deans of the CCSF Chinatown/North Beach and Mission District Campuses revealed that challenges for construction and modernization projects in the San Francisco City College system derive more from external stakeholder concerns than internal governance systems. In particular, the study focused on a satellite campus dean's role in the shared governance system for CCSF construction projects and how they effectively work in conjunction with CCSF leadership to garner community support, while mediating external opposition for projects. Findings from the study concurred in part with current literature regarding construction delays related to external stakeholder opposition and the role college administrators must play in ameliorating environmental, historical preservation, and corporate interest concerns for projects. Specifically, campus deans in the San Francisco City College system found that the practices of conducting information hearing sessions and forming internal/external/community advisory committees facilitated productive forums for hearing the concerns of key campus personnel and community stakeholders. Additionally, these practices allowed for more efficient project execution and the promotion of improved community relations within the neighboring communities for the campus projects in this study.

This thesis for the master of architecture degree focuses on the particular requirements for Senior Citizen Center in San Francisco.In the traditional society of the West, things did not change quickly, and people did not frequently move from one place to another; but this present-day society is one of dynamic suburbs; villages and towns can change their appearances in a very short time. The treatment of older people in contemporary society has caused many of them to feel alienated from the mainstream. Technical progress and the “rational” organization of present day civilization has largely eliminated the aged as persons having more experience that may beneficially be shared with the rest of us. I believe it is important to consider and respect the value of elderly people.My chosen program and site for this creative project is to design and solve the main problems of high density, the location, and the existing environments.In my own country of Thailand, there are only a few places specifically built for homeless elderly. It is very interesting therefore for me to explore and acquire knowledge for the design of Senior Citizen Center in the United States. There is a certain potential for this being useful someday in my own country.

From 2011 to 2012, the Modesto Irrigation District (MID) and the San Francisco Public Utilities Commission (SFPUC) attempted to broker a deal that would transfer water from the rural Central California district to the metropolitan Bay Area. With a contract length of 50 years, it represented the type of long--term agricultural--to--urban water deal many experts had long anticipated occurring in Northern California, and might open the door for larger transfer deals in the region. Such transfers had been extolled for years by economists, policymakers, and even some environmentalists as an optimal way to manage scarce water resources among a variety of interests. This optimism was countered by those fearing potential social, economic, and environmental harm that such deals would bring upon those not directly involved in the negotiation, known as "third parties," and literature suggested these third--party concerns were a major hurdle in completing transfer deals. The SFPUC--MID proposal fell through in September of 2012, and this thesis set out to explore the key factors in its collapse using an institutional framework. Analyzing data collected through detailed interviews and primary sources, this thesis concluded that third--party concerns played only a tertiary role in the termination of the negotiations. Far more consequential factors were rifts within the MID, caused in large part by the election of a board member adamantly opposed to the transfer, and the threat of legal action by the city of Modesto, already engaged in a contract with the MID. These spheres of conflict--within the negotiating agency, among contractual partners, and outside by third parties--combined to scuttle the deal. As a result of the failed transfer, the two agencies are taking two very different paths forward, with the SFPUC considering a similar water deal with a different irrigation district while the MID, after an overhaul of personnel, will tackle its challenges with a completely new management approach. The thesis concludes with recommendations for those in the water management field, the most significant regarding the importance of dry year arrangements and the capacity of institutional leveraging.

Conventional methods for health assessment of wild-caught and stranded seals were used to describe the disease status of harbor seals in California. Clinical chemistry, infectious disease prevalence, immune function, and contaminant data were collected to evaluate harbor seal health with data collected from three groups of seals. Wild-caught seals of all ages were sampled at two locations: San Francisco Bay (a heavily urbanized estuary) and Tomales Bay (a less developed control site). Stranded seals entered rehabilitation from a more extensive portion of the California coast which included the locations where seals were caught. Hematology reference intervals were generated to provide a baseline for health assessment among the seals. Individual variability in blood variables among seals was affected by age, sex, location, and girth. Disease surveillance focused on pathogens known to cause lesions in harbor seals, zoonoses, and those with terrestrial sources. Specific pathogens of interest were E coli, Clostridium perfringens, Vibrio spp, Campylobacter spp, Salmonella, Giardia, Cryptosporidium, avian influenza virus, Brucella, Leptospira spp., Toxoplasma gondii, Sarcocystis neurona, and Neospora caninum, Leptospira spp, and phocine and canine distemper virus. There was evidence of exposure to all pathogens except for phocine distemper virus. Simple measures of immune response were used to evaluate the immune function of harbor seal pups in rehabilitation that had evidence of previous bacterial infection. The swelling response to a subcutaneous injection of phytohemagglutinin (PHA) was positively associated with growth rate, possibly illustrating the energetic trade-offs between growth and immunity. Blubber contaminant concentrations (PCBs, DDTs, PBDEs, CHLDs, and HCHs) in harbor seal pups were grouped by extent of suckling and strand location. The ratio of PCB:DDT was increased in San Francisco Bay and decreased in Monterey Bay compared with other locations along the coast. Pups that weaned in the wild, lost weight and then stranded had the highest contaminant levels, equivalent to the concentrations detected in stranded adult harbor seals. Dispersal and survival were monitored by satellite telemetry in harbor seal pups released from rehabilitation and recently weaned wild-caught pups to assess the effect of condition, health, and contaminant levels on survival probability. Increased contaminant levels and decreased thyroxine (T4) were associated with decreased survival probability. Increased mass, particularly among the rehabilitated pups, was associated with increased survival probability. This study demonstrates that health and survival of harbor seals pups along the central California coast are impacted by human activities such as contaminant disposal, pathogen pollution and boat traffic, although the variability in individual health measures requires carefully designed studies to detect these effects.

In this study, I use bioarchaeological data derived from human burials to evaluate subsistence change in mid-to-late Holocene central California (circa 4950-200 B.P.). Previous investigations in the region have proposed two competing models to account for changes in subsistence patterns. The seasonal stress hypothesis argues that the increased reliance on acorns and small seeds during the late Holocene led to improved health status, since these resources could be stored and used as a “buffer” against seasonal food shortages. In contrast, resource intensification models predict temporal declines in health during the late Holocene, as measured by a decline in dietary quality and health status, increased population crowding, and greater levels of sedentism. I test the hypothesis that health status, as measured by childhood stress and disease indicators, declined during the late Holocene in central California. I analyzed 511 human skeletons from ten archaeological sites in the Sacramento Valley and San Francisco Bay area to investigate temporal and spatial variability in diet and health. I analyzed a subset (n = 111) of this sample to evaluate prehistoric dietary patterns using carbon and nitrogen stable isotope ratios. Indicators of health status show significant temporal and regional variation. In the Valley, tibial periosteal reactions, porotic hyperostosis, and enamel hypoplasias significantly increased through time, implying a decline in health status. In the Bay, health indicators show little temporal variability. However, inter-regional comparisons indicate a higher prevalence of stress and disease indicators among Bay Area skeletons than in the Valley skeletal series. The stable isotope data from human bone collagen and apatite also indicate significant interregional differences in prehistoric diets between the Bay and the Valley. In the Bay, diets shifted from high trophic level marine foods to a more terrestrially focused diet over time. In the Valley, there are no significant dietary trends observed in the data. Dental caries and antemortem tooth loss are significantly more prevalent in the Valley than in the Bay, and closely match the isotopic findings. The paleopathological findings provide support for late Holocene resource intensification models posited for the Valley, but not for the Bay Area.

Reliable estimates of river discharge and sediment transport to the ocean from large tidal rivers are vital for water resources management, efficient river and harbor management, navigational purposes, and climate analyses. Due to the difficulties inherent in measuring tidal-river discharge, hydrological and sedimentological records are typically too short to adequately characterize long-term (decadal) trends. Also, uncertainties associated with observation and calibration of hydrological models suggest a need for more accurate methods based on longer records of hydrodynamic parameters (e.g. tides). Tidal theory indicates that tides and river discharge interact through quadratic bed friction, which diminishes and distorts the tidal wave as discharge increases. In this study, using tidal constituents, astronomical forcing and a model of the frictional interaction of flow and tides, I propose a novel Tidal Discharge Estimate (TDE) to predict freshwater discharge with an approximate averaging interval of 18 days for time periods with tidal data but no river flow records. Next, using continuous wavelet analysis of tidal properties, I develop a method of estimating river discharge using tides measured on multiple gages along tidal rivers to improve the time-resolution and accuracy of TDE. The applicability of the Multiple-gauge Discharge Estimate (MTDE) is first demonstrated in the two largest tidal-fluvial systems of the Pacific Northwest, the Columbia River Estuary (CRE) and Fraser River Estuary (FRE). A numerical model of an idealized estuary with similar forcing as the FRE and CRE is next run under different hydrologic and morphologic scenarios to evaluate the effect of convergence, friction, and river flow variations on the applicability of MTDE. The TDE method was applied to the San Francisco Bay, using the continuous hourly tide record available since 1858. Results show that TDE reproduces known San Francisco (SF) Bay delta inflows from 1930-present with a Nash-Sutcliffe coefficient of 0.81 and is a useful method for hindcasting historical flows from 1858 - 1929, a period that predates direct measurement of delta discharge. I also recover and digitize ~80 years of Sacramento River daily water level data between 1849 and 1946, from which river discharge to SF Bay is estimated on a daily basis, after adjusting for changes to the river channel. This discharge combined with Net Delta Outflow Index estimates (1930 - 2011) and flow estimates from tidal data (1858 - 2011) provides a more accurate version of SF Bay historic daily inflows from 1849 - 2011. Next, the history of sediment transport and discharge into SF Bay from 1849-present is reevaluated using the daily discharge estimates. A non-stationary rating curve between river flow and sediment transport is developed, with net sedimentation observed during five bathymetric surveys that were used to constrain the total integrated sediment discharge. Results show that ~1600±320 million-tons of sediment have been delivered to SF Bay between 1850 and 2011. There has been an approximately 25 - 30% reduction of annual flow since the 19th century, along with decreased sediment supply. This has resulted in a ~60% reduction in annual sediment delivery to SF Bay. The annual hydrograph of inflow to SF Bay and the seasonality of sediment flux have changed considerably over time, due to both human alteration and climate change. Significant historic spring-melt peak floods have disappeared in the modern system and now peak flows mostly occur in winter. My flow estimation methods also confirm that the flood of January 1862 had the largest daily sediment load and the second largest daily discharge since 1849.

This study examines the interaction between two anarchist support groups for the homeless, Food Not Bombs and Homes Not Jails, and the city of San Francisco between 1988 and 1995. Food Not Bombs provides free meals in public spaces and protests government and corporate policies that harm the poor and homeless. Homes Not Jails is a sister group of Food Not Bombs that opens up unused houses and government buildings to provide housing for homeless residents. During the period 1988-1995, two mayors, progressive Art Agnos (1988-1991) and conservative Frank Jordan (1992-1995), mass-arrested members of Food Not Bombs for distributing food in city parks without a permit, handing out over 1,000 arrest and citations to members of the group in that eight year period. While squatting would seem to be a graver offense than distributing free food, Homes Not Jails was treated far more leniently by city officials during the Jordan administrations. I trace the difference in treatment of the two groups to the fact that Food Not Bombs engages in anarchist direct action in public space, while Homes Not Jails does so in private residences. The public nature of Food Not Bombs made them a visible threat to order to both Agnos and Jordan and one they had to confront and stop. While both mayoral administrations persecuted Food Not Bombs, they treated the organization in different ways, which derived from different conceptions of the cause of homelessness. Agnos saw homelessness as a result of structural inequalities and economic conditions and viewed state welfare programs as the only way to address the problem. In response to Food Not Bombs he tried to incorporate them into the broader charity apparatus of the state, and when that failed he used the police to force them into "negotiated management" with the city Jordan saw homelessness as a criminal and public safety problem and wanted to use the police to clean and reclaim the city for wealthier residents and tourists. Jordan saw Food Not Bombs as a threat to public order and tried to use his police force to exclude the group from public space.

This thesis attempts to grasp the creation of an image of a city, taking the case of waterfront cities where the presence of water becomes a sense of place. A phenomenological method was employed for investigating actual waterfront cities: Boston, Chicago, and San Francisco. Although a single method has yet to be established for studying a sense of place, phenomenology was adopted because it deals with the relationship between an environment and the experience of that environment. This thesis found some common qualities between these cities in their fonns. These qualities seem to have a certain relationship to the creation of the images of these waterfront cities. This study also brought up the question of how to evaluate personal experiences phenomenologically. They are related to the basis of this thesis. This shows us the difficulty of practicing the phenomenology and the profundity of studying an image of a city. At the same time, it is a step for further study.

ln mid-1988, Brigham Young University received a high-quality collection of photographic glass plates made by Edith Irvine at the tum of the century. The plates, her camera and other photographic equipment, and miscellaneous publications were donated to BYU by her nephew, Jim Irvine. When the plates arrived and the Archives Photolab had them proofed, we realized thal not only were the San Francisco earthquake/ fire and other areas of California history recorded, but we had, in fact, the work of an outstanding photographer. As we compared the proofs with the work of other photographers who handled similar subjects, we called on faculty members qualified to judge her work. All were unstinting in their praise. As our Archives Curator, Dennis Rowley, looked at them, he said, "I've never seen a sel of photographs create a mood like these do." The more I worked with them, the greater my need to do more than just process and preserve. As I discussed the collection with the faculty members, it became evident to me that I should make a change in my graduate program. I was determined to learn more about the photographer. The collection of photographs can be viewed in the Edith Irvine Collection.

En el planteamiento previo de este trabajo nos propusimos cinco objetivos que hemos desarrollado a lo largo del estudio y que se detallan a continuación. 1) Documentación del mural La documentación gráfica del mural ha consistido en la realización de un calco digital del mural en base al programa Photoshop y con la ayuda de la aplicación DStrech. A partir de la documentación gráfica hemos identificado 194 motivos en distintas categorías de figuras animales, humanas y elementos esquemáticos y abstractos distribuidos en cinco sectores de la cueva. Todos estos motivos están reproducidos a escala en el calco general y situados en la planimetría de la cavidad. Además, hemos elaborado una aplicación de base de datos específica para nuestras investigaciones referentes al arte rupestre de las sierras centrales de Baja California. La intención es tener unas descripciones estandarizadas que permitan comparar los datos formales de las figuras de una cavidad entre sí y respecto a otros murales. En este estudio incluimos la descripción de la base de datos y su funcionamiento, así como la información perteneciente a la cavidad de El Ratón en forma de ficha individual de cada figura. 2) Proceso de realización del mural La documentación del mural ha servido para establecer el orden de superposición de las figuras que están en contacto y muestran una estratigrafía cromática. El establecimiento de estas superposiciones no está exento de problemas, derivados principalmente de la apreciación del anclaje de los pigmentos, las transparencias de los colores, los repintes y las reelaboraciones de las figuras. A partir de esta información hemos establecido el proceso de ejecución del mural. Para ello hemos tenido también en consideración elementos compositivos y rasgos formales de las figuras pintadas. El resultado son siete fases consecutivas dentro del proceso muralista. Hemos detallado los puntos en la documentación en los que nos hemos basado para establecer el proceso para que pueda juzgarse su idoneidad, y proponemos estudios más detallados que incluyan la elaboración de láminas delgadas en algunos puntos del mural para cerciorarnos de las superposiciones. Por otra parte, hemos confrontado la propuesta de fases que hemos establecido en El Ratón con las fases que R. Viñas propuso para La Pintada y hemos podido apreciar que algunas formas que caracterizan fases consecutivas de La Pintada siguen el mismo patrón en El Ratón. Esto es especialmente apreciable en la evolución del perfil de los cuerpos y la posición de las patas de los cuadúpedos. 3) Contexto cronocultural Durante mucho tiempo los Grandes Murales se han considerado como un fenómeno relativamente homogéneo vinculado con la cultura Comondú, en un periodo de tiempo incluido en las últimas fases de la prehistoria bajacaliforniana. A partir de las observaciones en distintos murales, nuestro equipo de trabajo advirtió que las fases pictográficas que se observan en algunos frisos podían contravenir esta idea inicial y descubrir que el proceso pictográfico de las sierras centrales de Baja California es dilatado en el tiempo. La documentación realizada por R. Viñas en La Pintada y ahora la que presentamos para el caso de El Ratón confirman esta hipótesis: hay una diversidad de momentos pictóricos en los murales que evidencian cambios culturales en un proceso diacrónico dilatado. R. Viñas propone una distinción entre los Grandes Murales con distintas fases internas —en La Pintada propone cuatro fases para los Grandes Murales—; otra etapa pictórica con la inclusión de nuevas formas gráficas que mantendrían elementos de los Grandes Murales, a la que llama «Tradición Gran Mural», y una etapa final en la que predominan los elementos esquemáticos y abstractos y que se desvincula formalmente de los Grandes Murales. Este esquema coincide con nuestras observaciones en El Ratón, donde las fases 1-3 corresponden plenamente a los Grandes Murales, las fases 4 y 5 se incluirían en esa «Tradición Grandes Murales» y las 6 y 7 se apartan formalmente de esta tradición. No obstante, esta propuesta no deja de ser un esquema inicial y el fenómeno rupestre en Baja California es muy complejo como para pensar que a esta tendencia general no le podremos añadir nuevos matices cuando se documenten un mayor número de cavidades pintadas. Las fases finales del arte rupestre de Baja California corresponden a los habitantes de la península que conocieron a los colonizadores europeos. Otra cuestión es establecer el inicio del proceso y las fases intermedias. Las fechas directas sobre los murales establecen una antigüedad que se remonta al Arcaico temprano. La fecha que consideramos fiable obtenida del puma n.º 41 de la cueva de El Ratón (4.845 ±60 BP) es coherente con este entorno de dataciones. Sin embargo, no podemos dar la cuestión por zanjada. En el futuro se deberán establecer proyectos de datación que persigan objetivos específicos. Proponemos la búsqueda de fechas radiocarbónicas que relacionen figuras de las fases de la cronología relativa que se deriva de la documentación, en espera de una coherencia que dé sentido al estudio del proceso y que, posteriormente, sea comparable con el estudio de otros murales. En el caso de El Ratón, la documentación presentada facilita el proceso de selección de figuras potencialmente interesantes para confirmar o corregir la propuesta de las fases pictóricas. 4) Análisis de la composición gráfica del mural El análisis de la composición gráfica del mural nos ha permitido identificar relaciones entre distintas figuras o elementos internos de las pinturas que hemos interpretado como códigos del lenguaje muralista. Los pintores han utilizados los motivos iconográficos, formas, colores, contactos entre figuras, relaciones de simetría, ubicación en el espacio, líneas visuales, sucesiones, actitud y posición de las figuras para crear estos códigos. Estos se manifiestan en ocasiones por su valor recurrente, otras por contraste u oposición y se hacen evidentes en la composición de manera que resultan significativos. Las relaciones codificadas permiten identificar la temática representada dentro del mismo mural, y observar diferencias de estos tratamientos entre sus distintas fases. Conforme avance el estudio de los murales podremos establecer la distribución en extensión geográfica y profundidad histórica de estos códigos y así se convertirán en un elemento para discernir el proceso histórico de los murales rupestres de Baja California. Podremos ver también cómo estos recursos se asemejan o diferencian entre las sierras de San Francisco, Guadalupe y San Borja en una visión amplia del fenómeno de los Grandes Murales. 5) Funcionalidad de la cueva de El Ratón Las cuevas pintadas de la sierra de San Francisco han sido consideradas, a menudo, como agreggaton sites. Tal como fueron definidos para el Paleolítico, estos son yacimientos donde se reúne un grupo numeroso de personas para llevar a cabo una serie de rituales y actos sociales y se caracterizan por una ocupación de mucha gente por poco tiempo. Se espera que esto se refleje de alguna manera en el sedimento arqueológico y en consecuencia quede rastro de la estacionalidad que caracteriza a estas reuniones. Por otro lado, el sitio ha de reunir unas condiciones que permitan concentrar un número importante de asistentes, abundancia de elementos rituales muebles y un panel decorado que presente elementos singulares y decoraciones genéricas. En nuestra opinión, no todas las cuevas pintadas del área de los Grandes Murales cumplían la misma función. Esta apreciación deriva de las obvias diferencias entre distintos tipos de cuevas pintadas que conocemos en las sierras de San Francisco. No es lo mismo una cueva como La Pintada con más de mil figuras, una temática muy variada, muchas fases de realización del mural y una extensión considerable, que pequeñas oquedades que pueden encontrarse en varios barrancos con un número reducido de pinturas, u otras cavidades de mediano tamaño, un mural relativamente con pocas pinturas y una temática unitaria. Pero por el momento, no tenemos unas características definidas que categoricen los distintos tipos de cueva pintada ni siquiera estos sitios de congregación. En el caso de la cueva de El Ratón hemos confrontado sus datos con los provenientes de La Pintada, La Serpiente y El Porcelano y hemos visto que participan de ciertas similitudes y diferencias significativas. En primer lugar, las cuevas de La Pintada y El Ratón son amplias y con una terraza que permite la reunión de un grupo considerable de personas. La cueva de La Serpiente es una grieta en el cantil que apenas puede albergar un número muy reducido de personas y El Porcelano es una cueva mediana sin mucho espacio para grandes reuniones. Si a estas propiedades morfológicas añadimos las características de los respectivos murales vemos que El Ratón y La Pintada comparten rasgos comunes en contraste con los casos de La Serpiente y El Porcelano. Las cuevas de El Ratón y La Pintada presentan una considerable variabilidad de rasgos estilísticos y de recursos técnicos, una paleta de colores amplia y un repertorio iconográfico extenso, a tal punto que los porcentajes son muy similares. Por el contrario, El Porcelano y La Serpiente muestran una gran homogeneidad interna de rasgos estilísticos y de recursos técnicos, una paleta de colores casi monótona y poca variabilidad iconográfica. Es decir, tienen unos rasgos formales muy homogéneos en sus respectivos murales aunque sean dispares entre sí. Por otra parte, en El Ratón y La Pintada existe un proceso de realización prolongado en el tiempo, con distintas fases pictóricas y numerosas superposiciones. Las características de cuatro cuevas pintadas no son suficientes para caracterizar sitios arqueológicos complejos como son los murales pintados de Baja California. Sin embargo, esta comparación orienta en la búsqueda de estas características. De manera provisional y presumiblemente incompleta proponemos que las características que pueden definir los lugares de congregación en la sierra de San Francisco: — Lugares amplios que permitan la reunión de un número importante de gente. — Murales que presenten una considerable variabilidad de rasgos técnicos, estilísticos, cromáticos e iconográficos. — El proceso muralista será dilatado en el tiempo y mostrará diferentes fases. — Probablemente presentarán un tema principal que se complementará en las sucesivas etapas pictóricas y, en algunos casos, se añadirán nuevos temas. Distintos a estos grandes santuarios, podemos encontrar sitios con pinturas que respondan a una temática muy particular, realizados en un momento histórico concreto sin que el uso más o menos continuado del sitio haya requerido ampliar o modificar el mural. Pensamos que corresponden a lugares donde se han celebrado rituales más privados o que han sido pintados por algún motivo muy concreto. Por lo que se refiere al sedimento arqueológico, hemos de advertir que en las cuevas pintadas de estas sierras la potencia estratigráfica es pobre y que el número de excavaciones de que disponemos es escaso. Por eso no nos atrevemos a predecir cómo sería este sedimento en relación con las cuevas pintadas en lugares de congregación. En todo caso, diremos que en El Ratón no hemos identificado disposiciones de material significativas más allá de una concentración del material en hilera paralela a la pared, y que sí hemos documentado unas estructuras de combustión peculiares en cuanto a su función, que pensamos que están relacionadas con los rituales que se llevaron a cabo en este santuario rupestre. Hemos de añadir que la temática representada la cueva de El Ratón muestra una serie de relaciones con temas mitológicos documentados etnográficamente en el entorno cultural, lo que permite una propuesta interpretativa del mural en relación con aspectos astronómicos ligados a los solsticios y, por lo tanto, a la mitología de la renovación estacional y mantenimiento de la periodicidad. Esta propuesta precisa de un estudio más detallado que incluya observaciones in situ en los periodos señalados —especialmente durante el solsticio de verano— y cálculos arqueoastronómicos que abarquen los periodos históricos que nos interese documentar. Para finalizar, presentamos este trabajo del mural de El Ratón como un elemento a tener en cuenta en el estudio global de los Grandes Murales y con la esperanza de crear discusión al respecto. Consideramos que para avanzar necesitamos documentaciones exhaustivas de los murales y el análisis individualizado de los mismos para poder, luego, contrastarlos. Para ello es necesario desarrollar metodologías de documentación que permitan comparaciones parangonables. En este empeño seguiremos trabajando.
The archaeological site of El Ratón Cave: A painted cave in the Sierra de San Francisco (Baja California Sur, Mexico). The painted mural. Albert Rubio i Mora In a previous proposal of this work, we set out five aims which have been developed throughout the present research. These are described below. 1) Recording of the mural painting The visual recording of the mural painting consisted of making a digital carbon copy of the mural using the Photoshop software and with aid of the DStrech plugin. Using this visual record, we have identified 194 motifs of various classes, animal figures, humans, schematic and abstract designs, scattered over five sections in the cave. All of these motifs have been reproduced to scale on the general copy and located in the planimetry of the cave. Additionally, we have compiled a special database for researching the rock art of the Baja California central mountain ranges, or sierras. The aim is to create a resource of standardised descriptions that will allow researchers to compare the formal qualities of the motifs at both the intra- and inter-site levels. In this study, we have included the description of the database and its use, as well as documentation of the data from El Ratón Cave in individual records for each figure. 2) The creation process of the mural The work of recording the painted mural has been useful to establish the order of superimposition of the overlapping figures, which has revealed a chromatic stratigraphy. Determining the order of superimposing images is not without its problems, particularly due to the difficulty of perceiving the pigment background, the colour overlay, and the repainting and modification of the motifs. Using this information, we have been able to establish the sequence of the creation process of the mural. To reconstruct this process, we have also taken into account the composition and formal properties of the figures. The result reveals seven consecutive phases of the painting process. We have detailed the aspects of the record upon which the reconstruction of the work process is based so that it can be assessed. We suggest more specific studies that include making thin prints of some mural sections to corroborate the superimpositions. Finally, we have contrasted our proposal of sequential painting phases at El Ratón with the phases suggested by R. Viñas for La Pintada. We concluded that certain forms which characterize the consecutive phases at La Pintada follow the same pattern at El Ratón. This is better appreciated in the evolution of the profile of the bodies and the position of the quadruped’s feet. 3) Chrono-cultural context For a long time, the Great Murals were considered a relatively homogeneous phenomenon linked to the Comondú culture, which belongs to the latter period of the Baja Californian prehistory. According to the observations made in several rock art sites, our research team noticed that the sequential pictorial phases of some of the panels seemed to contradict that initial assumption and showed that, to the contrary, the painting tradition of the central mountain ranges of Baja California had a long time depth. The recording of La Pintada by R. Viñas and our own research at El Ratón corroborate the hypothesis that there are different painting events in the mural tradition which reflect cultural changes in a long diachronic process. R. Viñas has distinguished various internal phases within the Great Murals. Based on the analysis at La Pintada, he has suggested four Great Mural phases, one pictorial period that includes novel motifs that keep to the elements of the Great Murals, which he has called Great Mural Tradition, and a final phase dominated by schematic and abstract motifs, which is formally removed from the Great Murals. This scheme coincides with our observations at El Ratón, where phases 1 to 3 clearly correspond with the Great Murals, phases 4 and 5 belong to the Great Murals Tradition, and 6 to 7 move away from that tradition. Nevertheless, this proposal is only an initial scheme and the rock art of Baja California is too complex to think that this trend will remain unchanged as more painted sites are recorded. The final phases of the rock art of Baja California belong to the peoples that inhabited the peninsula when the European pioneers arrived. A more pressing issue is to establish the age of the initial and intermediate phases. The direct dates obtained from the paintings suggest an age going back to the early Archaic. The most reliable date, obtained from figure no. 41, the puma, at El Ratón Cave (4,845 +60 BP) is coherent with the range of those dates. However, the issue is not completely resolved. Future dating projects should have well-defined aims. We suggest that radiocarbon dates should concentrate on relating specific figures to the phases of the relative chronology derived from our observations, in order to make sense of the creation process and create a data set that may be compared across mural sites. In the case of El Ratón, our recording can help towards the selection of motifs that could be used for sampling, to test the sequence of pictorial phases. 4) Analysis of the mural’s visual composition The analysis of the visual composition of the mural has thrown light on the associations among figures or internal elements of the paintings, which we interpret as the codes of the mural’s language. To create such codes, the artists seem to have used the iconographic motifs, forms, colours, image overlaps, symmetry relations, location in space, visual lines, sequences, attitude and situation of the motifs. These codes may be identified by their recurrence, contrast, or opposition and become evidently meaningful in the total composition. The codified associations allow us to identify the themes represented in the mural and to distinguish differences between those associations across the various phases. As the research of the murals moves forward we will be able to establish the geographical distribution and historical depth of such codes so that they will become a component that will aid in clarifying the history of the Great Murals of Baja California. We may also be able to observe whether the codes are similar or different across the sierras of San Francisco, Guadalupe and San Borja, in order to obtain a general picture of the Great Mural phenomenon. 5) The function of Cueva del Ratón The painted caves of sierra de San Francisco have often been considered as ‘aggregation sites’. These type of sites, initially defined for the European Palaeolithic, are locations where a numerous group of people convene to carry out a series of rituals and social activities. Thus, they are characterized by a short but intensive occupation. This would somehow be reflected in the archaeological record, leaving some traces of the seasonality that generally typifies such gatherings. Furthermore, the aggregation site should comply with certain conditions to allow the concentration of a large number of attendants, and it should contain portable ritual objects and decorated panels that show singular elements and general motifs. In our opinion, not all painted caves in the region of the Great Murals had the same function. This observation is based on the obvious differences between the various types of painted caves that are known in Sierra de San Francisco. For example, a cave like La Pintada – with over a thousand figures, varied themes, a mural with several creation phases and a large extension – is not the same as the small crevices scattered across the various cliffs with only a few paintings, or the medium-sized rock shelters that contain panels with relatively few figures and one theme. For now, we do not have a fixed set of criteria to categorise the different types of painted caves, or the aggregation sites. In the case of El Ratón Cave, we have contrasted our data against the data from the sites of La Pintada, La Serpeinte and El Porcelano, and we have been able to observe certain meaningful similarities and differences. First, the caves of La Pintada and El Ratón are big and both have a gallery that would allow the gathering of a large group of people. La Serpiente cave is a cliff crevice that can allow access to only a small number of people, and El Porcelano is a medium-sized cave with not much space for a gathering. If these morphological characteristics are seen side by side with the properties of each site’s paintings, we observe that El Ratón and La Pintada share several common traits , whereas this is not the case with La Serpiente and El Porcelano. The caves of El Ratón and La Pintada both show a considerable range of stylistic properties and techniques, an extensive colour palette and iconographic repertoire, to the point that their percentages are quite similar. In contrast, El Porcelano and La Serpiente show a great internal homogeneity of stylistic properties and techniques, an almost monotone colour palette, and little iconographic variety. That is to say, the formal properties of each site’s paintings are very homogeneous, although very different between them. Furthermore, El Ratón and La Pintada reflect a long creation process with different painting phases an numerous superimpositions. The characteristics of just four painted caves are not enough to embody the complex archaeological phenomenon that is the Great Mural rock art of Baja California. However, our observations can guide our search for such criteria. Provisionally and presumably incompletely, we suggest certain characteristics that may define the aggregation sites in the sierra de San Francisco: - Large sites that allow the gathering of a great number of people. - Murals that show considerable variability of techniques, styles, colours, and motifs. - The creation process will have a long time depth and will show several work phases. - Are likely to depict a main theme that will be expanded upon in successive painting stages, and in some cases, new themes will be added. In contrast to the large sanctuaries, there are sites with paintings that portray a singular theme, painted in one single historical moment. Even if these sites were sometimes used continuously over time their murals were not extended or modified. We think that these sites may have been used to celebrate more private rituals or were painted with a very particular aim. Regarding the archaeological sediment, we must point out that the painted caves of the Baja Californian sierras have a poor stratigraphy and the number of excavations has been scarce. For this reason, we can not make any suggestions as to how the sediment of the painted caves would differ from that of aggregation sites. In any case, we will mention that at El Ratón we have not been able to identify any relevant accumulation of archaeological material apart from a concentration of objects aligned to the cave wall. We also recorded some peculiar combustion structures whose function, we believe, may be related to the rituals that were carried out at this rock sanctuary. In addition, the theme depicted at El Ratón Cave has a series of similarities with mythological subjects documented in the ethnography of the cultural region. This allows us to suggest an interpretive reading of the mural in regards of astronomical topics related to the solstices, and consequently to the myth of the seasonal rebirth and cyclic continuity. This suggestion requires a more detailed study that should include in situ observation of the mentioned dates – especially, the summer solstice- and archaeoastronomic calculations that include the historical period we want to research. --- Finally, we present this study of El Ratón mural as a contribution to the global study of the Great Murals, and with it we hope to open a scholarly discussion. We believe that to move forward in this field we need extensive records of the murals and an individual analysis that can be tested afterwards. To this aim we need to develop recording methods that allow us to make reasonable comparisons. We will keep working towards that end.

Many researchers argue the increasing reliance on sit/lie ordinances to regulate homeless people's use of public space is one in a suite of neoliberal policies that shape the geographies of public space in cities to serve the needs of global capital. However, these policies are developed at the local, not global, level as specific actors make claims in the public sphere that communicatively shape policy formation. Through comparative case study, this research asks, how do different actors, situated in specific local and global contexts, influence the adoption of sit/lie ordinances? I examine two cases of policymaking in Portland and San Francisco. I use discourse analytic strategies and thematic coding of newspapers, archival documents, and key informant interviews to look at policy-making processes as they occur in their political, social, and economic contexts. I focus especially on the role of language in policy-making, policy-making arenas, and actions of grassroots actors, drawing from three interdisciplinary literatures to develop an explanatory theory of policy-making. I find the four interrelated explanatory factors in policy-making were: the actors (neoliberal and right-to-the-city); the tactics they use; the policy talk they use; and the policy arenas. First, political processes provide windows of opportunity and determine arenas for political activities. The different policy arenas (citizen election, committee, council led, litigation, etc.) influence the audience that the actors care about, and thus the policy talk. Additionally, elected officials have a determining effect on which arenas they use, which in turns structures the opportunities for policy talk. Second, the arena influences the depth to which resisters can discuss the issues with the wider public and decision-makers. This may explain why the right-to-the-city frame may not have been used as much as the academic literature might suggest. Resisters find it much harder to use this framing with the general public or elected officials because it takes too much time to explain to those unfamiliar. Instead, they rely more on concepts that may be more familiar like the dependent poor and unequal impact of the law on minority groups. Third, I find local actors have different positions in the global economy, however on the local level their different avenues and strategies of involvement are due to local conditions rather than global ones. The location in the global political economy seems to be less important than local political decision making contexts and the actions of individuals who are locally powerful due to their economic status and political connections. This suggests room for resisters to use local politics to resist these ordinances, without having to take on the entire global economy. Finally, actors use different narratives to influence decision makers and each other, responding and shifting to competing frames over time. The change over time is important, as it shows how policy debates change based on influences from different actors. My findings suggest the framing of the original necessity for the policy can influence the policy trajectory, but actors can and do respond and successfully shift policy talks over time. The dissertation concludes with additional implications for grassroots practice based on these theoretical findings.

This study examines the attitudes of local elected officials regarding quality of life ordinances that impact the street homeless in Atlanta, Georgia, and San Francisco, California. The case study approach was employed. A closed and opened-ended questionnaire was employed to obtain data. Content and aggregate data analysis was also performed. Although the data indicates that there is political representation for the homeless in Atlanta and San Francisco, it is not substantive. That is, even though local government in Atlanta and San Francisco acknowledges the need and its willingness to build additional affordable housing, more energy, time, and resources must be utilized for the creation of affordable housing if governmental figures realistically expect to assist the homeless in securing permanent affordable housing. The data shows, however, that in addition to creating affordable housing, local government in Atlanta and San Francisco has devoted a significant amount of energy, time, and resources to control the behavior of the street homeless. The data analysis also shows that it is the residential and business communities leading the charge for enactment and strong enforcement of quality of life ordinances in both cities. This finding is consistent with Robert DeLeon’s study of local governance in San Francisco. DeLeon argues that San Francisco politics is best understood within the context of pluralism. My study basically shows that pluralism is at work regarding quality of life ordinances in San Francisco. On the other hand, this finding comes in opposition to what Clarence Stone found in his study of Atlanta: Stone concluded that Atlanta governance is best understood within a regime. Even though my study does not confirm that regime theory is inadequate in explaining governance in Atlanta, it does highlight that the residential and rank and file have a strong and significant voice in ensuring the creation and enforcement of quality of life ordinances in Atlanta. The data analysis also suggests that a relationship exists among council members who believe that the primary cause of homelessness in Atlanta and San Francisco, respectively, stems from personal defects and those who support quality of life ordinances. This finding is consistent when analyzing the attitudes of San Francisco Mayor Willie Brown regarding quality of life ordinances. Of respondents supporting quality of life ordinances, all indicated that the primary cause of homelessness in their respective cities falls within the personal perspective. At the other end of the spectrum, respondents who stated that the primary cause of homelessness is structural indicated opposition to quality of life ordinances.

Le California Camera Club, un collectif de photographes amateurs et professionnels actif à San Francisco notamment entre 1890 et 1915, est une organisation constamment marginalisée dans l’histoire de la photographie et de l’Ouest américain. En adoptant une double approche d’histoire culturelle et matérielle, cette thèse éclaire une gamme d’activités et de productions de ce club largement inconnu, qui ont contribué à forger l’identité d’une communauté éloignée de l’Ouest. Par son approche inclusive, réunissant plus de 400 membres en 1900, le club doit être considéré comme une organisation localement ancrée, qui se sert de la photographie pour produire un récit esthétiquement attirant et historiquement cohérent de la ville et de l’État. Malgré son chevauchement chronologique avec le pictorialisme et son ambition de faire reconnaître le médium parmi les beaux-arts, le corpus du club ne peut être inséré dans un canon d’histoire de l’art de la photographie. En se basant sur diverses stratégies de diffusion et d’exposition, les membres adoptent plutôt une approche collective qui transforme l’aspiration à la reconnaissance en un désir de légitimation régionale. À travers une analyse de pratiques photographiques, d’usages et d’itinéraires des objets, cette thèse retrace la construction d’une représentation idiosyncratique de la culture et de l’histoire californiennes par un club qui participe à la conquête d’une place légitime pour l’État sur la scène nationale. En mettant l’accent sur la dimension collective de la photographie, cette analyse montre comment sa pratique dans un territoire isolé mène à la construction imaginaire d’une communauté dotée d’une compréhension commune de ses valeurs esthétiques et de son histoire. L’enjeu de cette thèse est ainsi de réviser un schéma linéaire et étroit de l’histoire de la photographie en élargissant les perspectives géographiques, socioculturelles et archivistiques
The California Camera Club, a collective of amateur and professional photographers, most active in San Francisco between 1890 and 1915, represents a constantly marginalized organization in the history of photography and of the American West. By adopting a two-fold cultural-historical and material approach, this thesis sheds light on a largely unknown variety of Club activities and productions that served as meaningful elements to forge the identity of a remote Western community. Through its inclusive outlook, unifying more than 400 members in 1900, the Club must be considered a locally embedded organization that mobilized photography to produce an aesthetically pleasing and historically coherent narrative of the city and the state. Despite its chronological position in the period of Pictorialism and the striving for institutional recognition, the Club corpus cannot be inserted into an art-historical canon of photography. Rather, by drawing on diverse strategies of dissemination and exhibition, the members adopted a collective approach to the medium that turned the striving for institutional recognition into a desire for regional legitimation. Through an examination of photographic practices, uses, and object trajectories, this thesis traces the construction of an idiosyncratic representation of Californian culture and history by the Club, which actively assisted the state’s search for a legitimate national place. By focusing on the collective dimension of photography, the analysis demonstrates how the practice in an isolated territory led to the imagination of a community with shared aesthetic and historical understandings. The object of this thesis is to revise both linear and narrow tropes in the history of photography by broadening its geographic, sociocultural, archival perspectives

Le muralisme chicano, a la difference du mouvement muraliste mexicain des annees 1920, est ne de la lutte de cesar chavez. C'est au sein de la lutte de chavez et de son syndicat qu'apparaissent les signes avant-coureurs du muralisme chicano: la banniere de la vierge de guadalupe, l'aigle noir sur fond blanc et l'illustration graphique du journal el malcriado. Sur le plan socio-philosophique, le muralisme chicano a emerge du vide culturel: vide dans la formation des peintres ou exclusion des musees pour les artistes chicanos. Afin de pallier ces problemes, ils ont cree des centres culturels et alabore une conception de l'art non-occidentale. Dans les trois villes etudiees, le muralisme a ete tres different. A los angeles, le muralisme est ne des graffiti et a ete initie dans des cites tres pauvres par charles felix. Par la suite, de militant, le muralisme chicano est devenu environnemental. A san francisco, le muralisme chicano est ne du chomage et a pris un caractere multi-ethnique. A san diego, le muralisme est ne de la renovation urbaine et de la construction de "chicano park" pour lutter contre la construction du pont coronado. Nous avons trois mouvements muralistes chicanos. L'indigenisme est un thele recurrent dans les trois villes et est lie au plan espiritual de aztlan
Chicano mural painting in the united states was born within cesar chavez movement and the farmworkers movement. The banners of the virgin de guadalupe and the aztec eagle as well as graphic illustration in el malcriado are the signs that foretell the mural movement. On a socio-philosophical and esthetic levels, chicano murals emerged from a cultural nothingness both on the point of view of lack of education for some painters as well as the exclusion of chicano artists from the artistic scenne. That is why they created cultural centers and built up a non-occidental conception of art. In the three cities we studied, chicano murals were very different. In los angeles, chicano murals emerged from graffiti and was initiated in poor housing projects by charles felix. Afterwards, from militant chicano muralism became environmental. In san francisco, chicano muralism was born from unemployment and had a multi-ethnic charcter. In san diego, muralism was born from urban renewal and from the buildin of chicano park to. Struggle against the building of coronado bridge. So, in fact, we have three chicano mural movements. Indigenism is a recurrent theme in the three cities and is linked to the plan espiritua of aztlan

Cette thèse consacrée aux Indiens résidant dans la zone urbaine de San Francisco- Oakland- San José en Californie étudie les conditions de vie de cette communauté au cours de la deuxième moitié du vingtième siècle. Après un rappel historique sur les Indiens de la baie de San Francisco jusqu'à 1945, suit une analyse du mouvement de migration des habitants des réserves vers cette région au cours des années 1950 et 1960. Puis la situation et l'évolution récente des Indiens de l'agglomération sont décrites dans les domaines suivants: démographie, habitat, économie, emploi, éducation, santé, vie associative et culturelle. L'étude se termine par un retour sur le militantisme de la communauté dans les années 60 qui a abouti à l'occupation de l'île d'Alcatraz
This PhD dissertation about the Native Americans residing in the urban area of San Francisco-Oakland-San Jose in California studies the living conditions of this community during the second half of the twentieth century. After a summary of the history of the Bay Area Indians until 1945, comes an analysis of the migration of reservation inhabitants towards this region in the 1950's and 1960's. Then the situation and the recent evolution of the metropolitan area Indians are described in the following fields : demography, residential patterns, economy, work, family, education, health, associations and ethnic events. The end of this study recalls the community's activism in the 1960's that led to the occupation of the Alcatraz Island

The fluid history of serpentinites from three locations in the Franciscan Complex, San Rafael Mountains, California is evaluated with petrologic and stable isotope data that allow interpretation of the serpentinization history and tectonic origin of these rocks. Petrologic evidence shows that most samples were originally serpentinized in a relatively low temperature seafloor hydrothermal environment, but some rocks underwent subsequent recrystallization. Data obtained from serpentine-magnetite geothermometry indicate that the serpentinization temperatures ranged from 168°C to 306°C. Oxygen isotopic values suggest that the serpentinites may have originated in a forearc setting. Hydrogen isotopic values obtained do not reflect the original conditions of serpentinization, but indicate that the rocks subsequently underwent isotopic exchange with meteoric water once they were emplaced onto the continent.

This thesis examines the desire and efforts to 'do something' about what is variously called 'modern slavery' or 'human trafficking'. Neoabolitionist efforts to fight such phenomena are typically wedded to a simplistic and essentialist ontology, unaware of or rejecting their own performativity. The thesis is not about slavery: it is about the ethico-political problem of responsibility and hospitality toward the other in the context of contemporary anti-slavery. What constitutes an ethical response to modern slavery? I explore the often violent effects of particular answers to this question but ultimately argue that the focus on doing something (and knowing it) threatens the very possibility of hospitality - of an ethical response. Through a conceptual vocabulary of 'scenes' I explore the performative interrelation of ontology and ethics. It is intended to help resist the metaphysical seductions of ontology and moral urgency. Scenes bundle specific ontologies, frames, conjured histories and futures, roles and narrative structures, distributions of concern, desire and enjoyment. Response begins with the discursive and affective co-constitution of the self, the one to whom we respond, and the scene in which it takes place. Scene-specific forms of responsibility can operate as a defence against the full force of responsibility to the other. Chapters 1 and 2 develop the notion of scenes and explore how neoabolitionism sets its scenes and locates favoured solutions. The remaining chapters explore those solution areas. Chapter 3 looks at how a US movement against 'sex trafficking' in internet advertising reproduces a Manichean world of simplicity by a game of Whac-A-Mole with websites, ritualistic repetition of baseless 'facts', silencing of sex workers, and aggressive demonization of those who disagree or argue for greater complexity; Chapters 4 and 5 draw on time I spent in San Francisco with two very different organisations. One, Not For Sale, makes a product of experiencing neoabolitionism, joining together charity, capitalism, consumer enjoyment, technology and the excitement of a movement of 'true believers', producing innovative approaches but in the process reinforcing problematic gendered and colonial stereotypes. The other, Anti-trafficking Collaborative of the Bay Area, works quietly and tactically in a messy immigration system, aware of the political and performative nature of their work. They actively take responsibility for their own preconceptions and desires to ground a profoundly hospitable client-centred approach avoiding many pitfalls identified in earlier chapters. The thesis has a performative element woven through it - the ethos of the work is one of unsettling both existing practices and literatures, and the writer and reader. The concluding chapter explores the impossibility of hospitality, its interrelation with juridical subjectivity and the ethics demanding and giving accounts in light of the preceding chapters, suggesting a performative approach toward the other is possible.

This thesis explores issues surrounding the question of using a literature-based assignment to teach composition at the college freshman level. Following a review of the critical debate on the use of literature in the composition classroom, spanning the last five decades, a specific work of literature is used as the basis for a writing assignment to be given to a freshman composition class.

À partir de la décennie 1970, on voit surgir dans la plupart des métropoles en Occident des quartiers comprenant une grande concentration de ménages gays et d’établissements commerciaux destinés à cette clientèle. Les recherches menées sur le phénomène ont négligé de se pencher sur la façon dont la trajectoire de la communauté homosexuelle locale s’articule au parcours historique, politique et urbain de la ville où le quartier est situé. Ce travail vise à combler cette lacune et à éclairer la trajectoire qui a mené la population gay à s’approprier un espace urbain. Il dresse d’abord un panorama des quartiers étant devenus le secteur homosexuel de la ville et de la vie de ses habitants dans les métropoles de San Francisco, Paris et Montréal, à partir de sources secondaires sur l’urbanisation du quartier et sur la communauté gay locale depuis 1900 jusqu’à nos jours. Ensuite, il compare leur évolution selon une périodisation comportant deux axes principaux : l’époque où les homosexuels avaient un vécu clandestin dans la ville et la période où les gays cherchaient à vivre leur sexualité dans la sphère publique. Le résultat montre une trajectoire similaire où la sortie de la clandestinité aboutisse à un quartier ouvert, gentryfié et touristique qui passe par une formation de ghetto liée au contexte économique et politique national, mais aussi au cadre urbain de la ville. En identifiant les facteurs déterminants, il était possible de concevoir l’existence de figures types de quartier gay rendant possible la vie communautaire : le quartier gay portuaire et militant, le quartier symbole d’une culture et le quartier bastion ethnique.
Since the 70's most of major western cities have witnessed the proliferation of neighbourhoods with a large concentration of gay households as well as commercial establishments for this patrons. Previous research have neglected the correlation between the trajectory of homosexual community and the historical, political and urban course of the cities in which those neighbourhoods are located. This paper aims to fill that gap by analyzing the course which lead to the gay population to appropriate urban space. Firstly, through secondary sources about urbanization going back to the 1900, this study establishes an overview of locations that turned into the gay quarters of the city and that of the life of the inhabitants of the metropolitan areas of San Francisco, Paris and Montreal. Then their evolution is compared using two distinct periods: when homosexuals had a clandestine life in the city and the period when gay sought to live their sexuality in the public sphere. The result shows a similar trajectory where the exit of the underground lead to an open district, gentrified and touristic zone which goes through the formation of a ghetto strongly tied with the economic and politic spheres as well as with the urban background of the city. By identifying this scenario as key it was possible to conceive the existence of figures types of gay area making community life as possible: the port and militant gay district, the district symbol of a culture and the neighbourhood ethnic bastion.

This dissertation examines the intersections of urban redevelopment and sexual politics in San Francisco from the first calls for a comprehensive land-use plan in the early 1940s to the highpoint of landscape destruction in the mid 1960s. During the war years, city leaders and prominent citizens compiled and prioritized a list of postwar planning projects that included improvements to the mass transit system, redevelopment of the downtown waterfront, and expansion of the city’s tourism and convention facilities. The footprint of these projects necessitated the destruction of significant elements of the built environment, including cable car lines, low rent hotels, industrial zones, and nighttime entertainment districts. After the war, civic leaders, elected officials, business interests and newspaper publishers attempted to rally support for these projects and searched for new ways to assert control over the urban landscape. San Franciscans, however, resisted significant components of the post-war civic improvement program by mobilizing against plans to replace cable cars with buses, by voting down schemes to redevelop the waterfront, and by blocking efforts to expand the freeway network. In this larger context, gays and lesbians in San Francisco in the early 1960s organized as a response to displacement from the low-rent hotel and bar districts on the edge of an expanding downtown. Specific examples of the loss of gay social spaces due to redevelopment pressures include the destruction of a popular gay bar to make way for a new airline bus terminal; the acquisition and razing of several businesses on the waterfront that hosted a thriving gay subculture; and the closure of a gay-oriented movie house after it aroused the ire of neighborhood activists in the Haight Ashbury district. This dissertation builds on previous work that examines the cultural politics of urban landscape change, as well as literature on the formation of urban sexuality-base subcultures to argue that the material transformation of urban space played a fundamental role in the emergence of contemporary notions of sexual difference.

This thesis concerns the role played by the politics of space in the San Francisco Bay Area during the radical upheavals of the 1960s. Space, understood as both region or locality, on the one hand, and specific public spaces, on the other, mediated Sixties radicalism to a considerable extent. And nowhere was this clearer than in the San Francisco Bay Area. From the beginning of the decade to the end, the Bay Area constituted a dynamic space at the forefront of Movement activism, a territory at once American and yet somehow autonomous or exceptional. Moreover, struggles over space, from the early civil rights and free speech conflicts to People's Park, helped shape radical thought and action in the region. By the late 1960s, the Bay Area (in particular Berkeley) came to represent a revolutionary enclave, a free territory or liberated space. This reflected the existence of a self-confident radical consciousness which was becoming decidedly provincial. Yet. It is also true that the issues fought over, like People's Park, raised significant, indeed vital questions about the purpose of public space. A vibrant politics of space was placed on the agenda by Bay Area radicals in the Sixties, even as their own strategic thinking was being moulded by the politics of space itself.

Many social scientists have sought to understand the dynamics of personhood in Western modernity, asking in particular whether it can be said that personhood in 'the West' is more individualistic than is typical elsewhere. Following Marcel Mauss, a number of anthropologists have suggested that the dominance of commodity exchange in modern Western societies lays a basis for individualised social relations over and above the relational patterns of gift exchange prevalent in many smaller-scale societies. Theorists from Weber to Foucault have likewise suggested that rationalised institutions in Western modernity condition an individualisation of subjectivity. Members of the San Francisco Reclaiming Pagan tradition seek to challenge the individualism, atomisation and rationalisation of social life they associate with wider US society, through ritual magic, activism and community-building. At times, they are able to create numinous worlds of beauty and interconnection against what Weber calls the "disenchantment of the world" (Weber [1919]1991 :155), helping to forge, in part, a more relational basis to their sociality. In doing so, they foreground many sites of relationality that exist in US society under a veneer of individualism, from gift exchange among kin networks to corporeal dissolution in crowds. Yet, their theories and cosmologies also valorise a particular type of artistic, expressive individualism, while their practices absorb and mirror some of the individualising and rationalising tendencies of wider systems and discourses they seek to resist. As a result, patterns of personhood and sociality in Reclaiming illustrate some of the complexities obtaining in US sociality more broadly. Examining these complexities highlights the individualising effects modern Euro-American institutions can have on subjectivity, while calling into question any overly-simplistic link between Western societies and 'individualism'. As such, this study can contribute to the project other anthropologists of personhood have begun: of problematising the dichotomy of 'Western-individualism' and 'non-Western-sociocentrism' which has at times underpinned anthropological studies of personhood.

As the era of the digital economy approaches, the wave of "shared economy" in recent years has created economic benefits through the integration of mobile Internet platforms and idle assets. It has created new momentum for economic development through "supply" and "demand" for start-ups and funding from investors. This case study is about the successful digital economy startup in the transport sector, the Uber Technologies Inc.. In this research, we try to study Uber, as a case of "shared economy", by collecting a large number of Wall Street Journals (WSJ), extracting news materials, analyzing and summarizing them, and going through discussions of relevant focuses. The research method used in this study is the method of context analysis, which is based on gathering information using key words such as Uber's intellectual property rights, patents, copyrights, trademarks and trade secrets. This paper uses the role of the system of intellectual property rights, to explore the relevance between the management of intellectual property rights and the rapid development of the company. By analyzing the relevant meaning and using it as the theoretical basis of this study, in support with Uber's management point of view, this study explores the relationship between intellectual property rights management and the development of the company. Namely, how to create the competitive advantage of intellectual property rights? And to deduct the possible science and technology management issues emerging companies might face, while Uber's continues its global expansion. Finally, according to the Uber's WSJ news, this paper summarizes the key topics of WSJ as supporting data to support the six important findings of this study. From the research results, we can know the diversity of topics related to S & T management, as well as the particularity of management. This will enable digital technology start-ups to learn from others and create new areas of the “shared economy”.

A series of resonant column and torsional shear (RCTS) and large scale resonant column (LSRC) tests were performed to investigate the dynamic properties (shear modulus and material damping ratio) of municipal solid waste (MSW). the MSW materials were recovered from the Tri-Cities landfill adjacent to the San Francisco Bay in California. A total of 30 specimens 2.8-in. (71.1-mm) and 6.0-in. (152.4-mm) of old, fresh, and mixed MSW were reconstituted in accordance with established sample preparation procedures. Ten of specimens were small-diameter (2.8-in. (71.1-mm)) RCTS specimen and 20 specimens were larger (6.0-in. (152.4-mm)) LSRC specimens. Dynamic laboratory measurements were performed in the linear and nonlinear strain ranges. Test parameters affecting the dynamic properties in the linear range included: (1) duration of confinement, (2) isotropic total confining pressure, [sigma]o, (3) excitation frequency, f, and (4) specimen size. Other test parameters affecting dynamic properties in the nonlinear strain range were: (1) shearing strain amplitude, [gamma], (2) isotropic total confining pressure, (3) overconsolidation ratio, (4) number of loading cycles, and (5) excitation frequency. In addition, the effects on dynamic properties of MSW specimens of material parameters such as (1) waste composition, (2) water content, (3) unit weight of waste, and (4) particle size were evaluated. The total unit weights of old, fresh, and mixed MSW specimens were estimated during testing in the RCTS and LSRC devices. These estimated total unit weights in the laboratory were compared with those measured at other MSW landfills and were found to generally be less than the field measurements. At a given [sigma]o, Gmax decreases with decreasing weight percentage of soil-size (passing the 3/4-in. (19.1-mm) sieve) material. However, Dmin increases slightly with decreasing weight percentage of soil-size material. Another relationship was developed between estimated total unit weight, [gamma]t, and confining pressure, including weigh percentage of soil-size material. The Vs profiles of old, fresh, and mixed MSW specimens obtained in the laboratory tests were compared with those measured at other MSW landfills in situ. The 62 to 76% soil-size material groups are in good agreement with in-situ Vs profiles. The variation in normalized shear modulus and material damping ratio curves were patterned after the Darendeli model (2001) for different weight percentages of soilsize material. An empirical relationship between normalized shear modulus (G/Gmax) and modified material damping ratio (D-Dmin) was developed in the nonlinear strain range. As part of collaborative research project, nonlinear shear modulus reduction and material damping curves generated by The University of Texas at Austin (UT) and The University of California at Berkeley (UCB) were compared according to different weight percentages of soil-size material. Furthermore, nonlinear shear modulus reduction and material damping ratio curves generated by UT were also compared with ones previously proposed by other researchers.

The objective of this research is to examine the development of the California alcohol outlets over time and the relationship between neighborhood characteristics and densities of the alcohol outlets. Two types of advanced analyses were done after the usual preliminary description of data. Firstly, fixed and random effects linear regression were used for the county panel data across time (1945-2010) with a dummy variable added to capture the change in law regarding limitations on alcohol outlets density. Secondly, a Bayesian spatio-temporal Poisson regression of the census tract panel data was conducted to capture recent availability of population characteristics affecting outlet density. The spatial Conditional Autoregressive model was embedded in the Poisson regression to detect spatial dependency of unexplained variance of alcohol outlet density. The results show that the alcohol outlets density reduced under the limitation law over time. However, it was no more effective in reducing the growth of alcohol outlets after the limitation was modified to be more restrictive. Poorer, higher vacancy rate and lower percentage of Black neighborhoods tend to have higher alcohol outlet density (numbers of alcohol outlets to population ratio) for both on-sale general and off-sale general. Other characteristics like percentage of Hispanics, percentage of Asians, percentage of younger population and median income of adjacency neighbors were associated with densities of on-sale general and off sale general alcohol outlets. Some regions like the San Francisco Bay area and the Greater Los Angeles area have more alcohol outlets than the predictions of neighborhood characteristics included in the model.

The Franciscan Complex forms the structurally complicated, locally chaotic basement of the Northern and Central California and southwestern Oregon Coast Ranges. It is an accretionary wedge formed during the Late- Jurassic-Tertiary subduction along the west coast of North America. In northern California, the Franciscan is subdivided into three belts, the Western, Central, and Coastal belts, which show a zonation in age, metamorphic “grade”, and structural style. Franciscan mélanges are present in the Central belt, as well as the Diablo Range --a tectonic window within the structurally overlying Great Valley Group--, and the Nacimiento Block, where the study area is located. One of the best exposures of Franciscan mélange, where contact relationships between blocks and matrix can be observed, crops out along 6 km of seacliffs near San Simeon. Boudinaged blocks of graywacke, greenstone, chert, and much rarer blueschist and graphite-schist are ix dispersed in the shale matrix. Block sizes range from 10 cm to 15 m. The discovery of interlayered blueschist and graphite-schists, and the presence of lawsonite in some graphite-schists demonstrates that these two lithologies were metamorphosed together. Graphite-schist blocks in the Franciscan have not been reported prior to this study. Two main mineral assemblages were recognized among the studied 34 mafic blueschist blocks: 1) Lws + Na-amp + Pmp + Phe + Ttn + Chl recrystallized at ~5 kbar and 200-250°C, and 2) Lws + Na-amp + Pmp + Phe + Ttn + Ep + Chl, which recrystallized under slightly higher temperatures but similar pressures (300-350°C, at 5 kbar). A pre-blueschist facies metamorphic event under greenschist facies conditions is recorded by calcic cores overprinted by Na-amp rims in about half of the blocks. Sodic amphibole rims with a higher Fe3+ content probably developed due to the breakdown of epidote during a decrease in T. These mafic blueschists followed a counterclockwise P-T path. Remnants of “actinolitic rinds”, which are reaction zones formed when the blocks were in contact with serpentine, were found associated with nine of the studied mafic blueschist blocks. Such rinds were thought to be unique to better-studied Franciscan high-T blocks. Graphite-schist blocks (30 studied) contain Qtz + Phen + Ab + Gr, and are of two types. One type has relict sedimentary textures with a weak foliation defined by graphite and pressure solution seams. The other type has a compositional layering with layers containing well recrystallized quartz. Nine of these blocks also contain lawsonite within the more graphitic layers. The geochemistry of the blueschist blocks indicates that they were derived from the MORB-like oceanic crust, and seamounts underplated during the initiation of subduction. The mainly mafic protolith contained a small volume of interlayered sediment, as indicated by the presence of associated metasedimentary graphite-schists. Blueschist facies conditions were attained at the bottom of the overriding plate during the initial states of Franciscan subduction (150-155 Ma). Mafic material continued to be underplated, and low-T dynamic blueschist-facies metamorphism continued to form until at least ~137 Ma. A model is proposed in which exhumation was facilitated by normal faulting near the surface driven by gravitational collapse driven by decrease in subduction plate dip around 80 Ma that is known to have caused the Laramide orogeny. During this time, blueschist and graphite-schist blocks were plucked from the bottom of the hanging wall, incorporated into the shaleand water-rich shear zone at the plate interface, and exhumed during the upward flow of mélange driven by the movement of the downgoing plate. Blocks were extended and boudinaged, and metasomatically altered in the cataclastic zones that developed along necks and margins of the blocks during upwelling and the dewatering that led to final compaction near the surface.

Shoulder pain was constantly reported as a problematic symptom causing dysfunction and quality of life interference after neck dissection in head and neck cancer patients. Due to a lack of conceptual framework and inconsistency of instrument selection, a comparison among previous studies was almost impossible, making it difficult to understand the phenomenon. The current study applied the University of California, San Francisco School of Nursing Symptom Management Model. The purposes of the study were to (a) describe the symptom experience of shoulder pain at 1 month after neck dissection, (b) describe the relationships among symptom experience of shoulder pain, functional status, and quality of life, and (c) identify the contextual variables, concurrent symptoms, and/or adherence predicting symptom experience of shoulder pain, functional status, and/or quality of life. This was a descriptive study with a convenience sample of head and neck cancer patients. The data were collected via a medical record review, a self-administered survey, and a physical examination. The data from 29 patients were entered for descriptive statistics, Pearson correlations, and multiple regressions. At 1 month after surgery, 62% of patients reported they had shoulder pain at some point within a week. Their shoulder pain was from mild to moderate. Fifty-nine percent complained that shoulder pain bothered them about the moderated level. In the final model, symptom experience, shoulder pain, was significantly correlated with one outcome, active shoulder abduction, but not the other, total quality of life, generic quality of life, and head and neck quality of life. Active shoulder abduction was significantly correlated with three quality of life measures. Adding significant predictors of symptom experience and outcomes into the final model, there is a potential that the model would be useful to guide treatment strategies. Treatment for myofascial pain of the levator scapulae could relieve shoulder pain after neck dissection and improve head and neck quality of life. Those with level V dissection were high risk populations of developing shoulder pain. Risk factors of quality of life, which were depression, loss of sensation, and radiation would describe how an intervention could change or unchange the patient’s life.
