Full textAbstract:
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.

Full textAbstract:
CHDS State/Local<br>Approved for public release; distribution is unlimited<br>Within the San Francisco Bay Area there are four cities that host a Metropolitan Medical Response System (MMRS) program: San Francisco, San Jose, Oakland and Fremont. The four Bay Area MMRS cities are within fifty miles of each other. The MMRS resources could be used to reinforce each other's planning and response. The 103-city, 10-county Bay Area is under one Urban Area Security Initiative (UASI). Currently though, the MMRS programs in the four cities work independently of each other and of the UASI. How can these agencies collaborate to address mission gaps and overlaps? This thesis uses a Delphi survey methodology to ascertain institutional perspectives on benefits, processes, enablers and barriers to collaboration in the San Francisco Bay Area. With collaborative effort, gaps and overlaps in San Francisco Bay Area mass casualty preparedness and response can be mitigated. This thesis recommends short term and long term actions to encourage collaboration in the Bay Area, which, in turn, can lead to better patient outcomes in infrequent mass casualty incidents.

Full textAbstract:
This paper hopes to analyze the intersection between diversity and numbers of visitors and landscape preservation in the National Park Service. Current scholarship addresses either diversity in the Park System or carrying capacity and human population pressures. However, both are critical issues facing the National Park Service in the 21st century, and looking at the issues in isolation means missing a key interaction and potentially working to solve one problem that in turn amplifies another. Here, diversity of park-goers and preservation priorities will be addressed together, each as part of the other.
Pinnacles National Park, Golden Gate National Recreation Area, and Muir Woods National Monument each face human population pressures, yet each park has unique issues that illuminate the larger struggles within in NPS to ensure its mission to preserve unimpaired the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations is still being met 100 years after conception.

Full textAbstract:
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.

Full textAbstract:
Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2010.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 116-118).<br>It is not only coastal conditions, but inland ones, that can inform an approach to and process of wetland adaptation in the face of sea level rise. A particular watershed clip in Alameda County, located in South San Francisco Bay, is taken as a test case in order to assess this hypothesis. The site is selected from a set of nested types of more general coastal and fluvial conditions. This thesis traverses multiple landscape scales in this way. The nested types include a coastal DNA structure, which reflects divergent watersheds draining to the Bay. These watershed types contain layered political boundaries, which themselves exhibit an array of differing hydrologic, demographic, economic and hardscape conditions. These conditions within conditions, reaching across scales, merit very particular treatments. Organ Trade contributes a new processing tool for wetland adaptation, beginning on the Bay Area's coasts, and reaching up through existing channels and streams where they exist. Even where fluvial availability is minimal, Organ Trade proposes a mechanism of dross acquisition in order to create a discontinuous but networked sponge-like layer for water retention. The thesis posits that inland riparian and hardscape management (inland infrastructure realignment - where infrastructure is taken to mean a broad array of items - that promotes fluvial enhancements and the creation of space for water retention) can help get the threatened coastal wetland system back in equilibrium. This thesis operates on the informed assumptions that (a) wetlands are organs of the Bay's anthropological and ecological order, (b) that these organs can be thought of as part of a closed system that functions maximally when in equilibrium, (c) that the system is threatened by an event external to itself, sea level rise, (d) that all elements essential to restoring equilibrium are and always have been within the system itself (hydrology, sediment, salinity, vegetation), and that (e) a calculated and transdisciplinary organ trade is a useful way of thinking about sea level rise adaptation in an urbanized estuary. This thesis begins to amass strategies that recreate the services, functions and values of threatened wetlands in an urbanized estuary. Wetland loss will be quantified most simply as the square kilometers of coastal wetlands inundated under 40cm and 140cm projections made by the Pacific Institute and the San Francisco Bay Conservation and Development Commission (BCDC). If wetlands cannot accrete quickly or efficiently enough to keep pace with sea level rise, this poses a serious threat to the ecological, cultural and economic wellbeing of the entire Bay. Additionally, because of the way the Bay Area has urbanized over time (creating a ring of thick, heavy infrastructure and human artefact only a short distance from the estuarine edge), almost no new wetlands can be created near coasts, and wetlands have little to no room to naturally migrate inland. Therefore, a compensatory trading system becomes a logical necessity, quantification for which is not within the scope of this thesis, but for which visioning and a systemic design approach can begin to be written about and shown graphically. Organ Trade offers a mapping methodology and set of tactics to make wetland trading decisions.<br>by Cristina Ungureanu.<br>M.C.P.

Overton, Cory Tyler. "Tidally-induced limits to California clapper rail ecology in San Francisco bay salt marshes." Thesis, University of California, Davis, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3614256.
Full textAbstract:
<p> The state and federally endangered California clapper rail (<i> Rallus longirostris obsoletus</i>) 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 (<i>Spartina </i> sp.), short pickleweed (<i>Sarcocornia pacifica</i>) in mid-elevation ranges, and gumplant (<i>Grindela humilis</i>) in the high marsh. Invasive Spartina (<i>Spartina foliosa x alterniflora </i>) grows taller and thicker than native Pacific cordgrass (<i> Spartina foliosa</i>). 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.</p>

Full textAbstract:
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.<br>Department of Architecture

Thesis (S.M. and M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2002.<br>Includes bibliographical references (leaves 90-93).<br>This thesis explores the belief that affordable housing has a negative impact on surrounding housing values. Currently, the San Francisco Bay Area is experiencing a housing shortage. The results of this housing crunch are most acutely felt by low income families who can no longer afford to live in the region. The housing shortage also threatens to undermine the economic competitiveness of the San Francisco Bay Area as it becomes increasingly difficult for employers to attract employees due the area's high cost of living. In order to solve the housing shortage, affordable housing needs to be developed on a regional scale, in both urban and suburban areas. However, affordable housing developers often face extreme opposition to new developments. The most common argument against affordable housing is the belief that housing for low income families will lead to property and neighborhood degradation, resulting in decreased housing values. Through a rigorous quantitative analysis this thesis argues that the introduction of an affordable housing development into a neighborhood does not reduce surrounding housing sales prices.<br>by Emily R.

Full textAbstract:
<p>Within the San Francisco Bay Area, Western Snowy Plovers (<i>Alexandrinus nivosus nivosus</i>) nest and winter in former salt ponds. They face a number of threats including human-altered habitats and high levels of predation by mesopredators and raptors. The South Bay Salt Pond Restoration Project (the Project) is a large wetland restoration project that will change and potentially eliminate Snowy Plover habitat in the region. As the Project returns salt ponds to tidal wetland, there will be less of the dry, flat, and sparsely vegetated habitat that plovers need for breeding and wintering habitat. A greater understanding of the specific microhabitat requirements for high quality plover foraging sites is needed. In particular, it is important for managers to understand what constitutes high quality wintering habitat for Snowy Plover numbers. This study assessed the characteristics at sites where Snowy Plovers winter in former salt ponds, especially habitat traits related to promoting plover foraging. Analysis of plover foraging habitat showed that plovers were associated with increasing plant height, water cover, and distance from perches and levees. This information is designed to inform restoration and management decisions in efforts to meet Snowy Plover recovery goals in the South San Francisco Bay. </p>

La possibilité des catastrophes nous oblige à repenser les définitions progressives, non-linéaires ("l'instauration," dans le vocabulaire d'Etienne Souriau) des concepts de risque, d'espace et d'expertise.

Avec les outils de la géographie et des études des sciences et technologies, nous nous pencherons sur le système complexe de relations qui co-construit le risque de tremblements de terre et regarderons la façon dont son instauration progressive entraine des transformations dans l'aménagement et la pratique de l'espace, la définition du risque, et, finalement, dans la figure de l'expert.

Following a symmetrical approach, this work explores several moving dimensions of the subject and space “at risk” in the San Francisco Bay Area, within the shared experience of an epistemic community waiting for a major earthquake - “the Big One” - to unfold. With a Geography, Science and Technologies Studies perspectives, we will look at the complex system of relations that co-construct the risk of earthquakes and the ways in which this successive instauration convene transformations in the making of space, the definition of risk, and finally, the translation of this scientific work into public policies and the figure of the expert. Drawing from in-depth empirical research of the Bay Area, analyzing the community of “Earthquake Junkies”—as these experts called themselves—and other risk-conscious residents, this work emphasizes the role of experience and emotions in multiple interlaced processes, connecting risk, space, and expertise. Following this exploration will see that the rigid definition that have separated science and experience, rationality and emotion, expertise and lay perception should be recomposed in favor of a more systematic approach that takes into account the role of the different dimensions of knowledge. As a prospect for a better understanding of the complex definition of risk in the public sphere, this research also proposes a framework to think about the definition of the subject “at risk,” as well as allows for reflection on the establishment of closest relation between scientific and non-scientific knowledge

Full textAbstract:
There is currently a project underway to restore many of the man-made salt ponds along the shores of South San Francisco Bay (SSFB) back to tidal marsh, potentially reestablishing these areas as sinks for SSFB sediments. While there have been recent studies examining the evolution of newly restored marsh areas in SSFB, there have been no recent projects focusing on the expected response of valuable tidal flat environments adjacent to the restored marshes. To help fill this void, this project seeks to characterize SSFB tidal flat morphodynamics, both spatially and temporally, through examination of historic morphologic variability and change along with variations in external forcings.
Spatial and temporal trends in profiles of SSFB tidal flats are examined using bathymetric and LIDAR data collected between the 1890s and 2005. Eigenfunction analysis reveals a dominant mode of morphologic variability related to the degree of convexity or concavity in cross shore profile – classically indicative of tidally dominant, sediment rich, or wave dominant, sediment poor conditions, respectively.
Two opposing areas of equilibrium shape – north/south of a constriction in estuary width located at the Dumbarton Bridge – are highlighted by the first mode of variability in the Eigenfunction analysis, accounting for 90% of the overall spatial variation in tidal flat shape. Additionally, the eigenfunction scores which quantify the spatial pattern of increasing/decreasing convexity in the inner/outer estuary are correlated to spatial variability in fetch length, sediment grain size, recent erosion/deposition, and tidal height. Results for spatial variation found herein are generally consistent with theoretical predictions of tidal flat morphologic response to waves, tides, and sediment supply.
Trends for morphologic change between 1890 and 2005 in twelve geographically diverse regions within SSFB are compared to temporal trends in sediment discharge, mean sea level, diurnal tidal range, and Pacific Decadal Oscillation Index (as a proxy for storminess). Overall, convex vs. concave profiles were favored in the inner vs. outer estuary throughout the entire historical period. Furthermore, tidal flat morphology of the outer estuary displayed a steady increase in concavity with time. The trend of increasing concavity in the outer-estuary flats was consistent with temporal changes in hindcasted sediment discharge from the Central Valley. Although consistently convex, tidal flats located in the inner portions of SSFB exhibited greater complexity in their degree of convexity through time, and temporal changes could not easily be correlated to a given external physical forcing, suggesting a possible role for more localized variations in sediment supply.
A set of criteria for establishing dependence between morphology and external factors was created, using results of a stepwise multiple regression. Using this criteria, trends sediment supply from the Central Valley were found to have a consistency with temporal trends in outerestuary tidal flat shape. Inner-estuary flat shape change was found to be consistent with local patterns in rainfall (as a proxy for local sediment discharge) in the innermost regions, and with recent deposition or erosion in all other regions.

Full textAbstract:
<p> This study focuses on how secular, governmental, and ecclesiastical Hispanic Empire institutions influenced the response and resistance of San Francisco Native American groups from 1769 to 1846. This project draws on late 18th and early 19th century primary Spanish documents and secondary sources to help understand the context of indigenous people's adaptive and response behaviors during this period as well as the nuances of their perspective and experience. Using both electronic and physical documents from a number of archival databases, primary Spanish documents were translated and correlated with baptismal and death mission records. This allowed for formulating alternative perspectives and putting indigenous response and resistance into context. The results of this study indicated that when acts of resistance to the colonial mission system led by charismatic Native American leaders are placed into chronological order, it appears these responses did not consist of isolated incidents. Rather, they appear to be connected through complex networks of communication and organization, and formal Native American armed resistance grew more intensive over time.</p>

Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2013.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 59-63).<br>In controversies over environmental management, participants often call for policies based on the best available science. However, environmental controversies are rarely simply disputes over scientific knowledge; instead, they are driven by stakeholders' conflicting interests and values. In this context, science often becomes a part of the political dispute, used and interpreted differently by different actors in the policy process. Scientists, therefore, face the challenge of communicating their research to non-scientific audiences-such as stakeholders, policy makers, and the general public-in a highly politicized context. This essay examines how scientists perceive their role in the policy process and how they navigate the intersection of science and policy in the San Francisco Bay-Delta, a region that has been the site of decades of scientific research and controversy over environmental management. This essay examines three cases: the CALFED Science Program, which built a policy-neutral body of research to support a collaborative planning process in the Bay-Delta that began in 2000; the interdisciplinary Bay- Delta policy reports which scientists from the University of California, Davis and the Public Policy Institute of California (PPIC) have published from 2007 to 2013 in reaction to policy failures; and a series of radio stories and interactive web maps that the San Francisco Estuary Institute (SFEI) produced in 2012 with KQED, a San-Francisco-based public media station, to communicate their research to a general California audience. These cases show how scientists in the Bay-Delta have struggled with the tension between communicating their research in a way that is salient to policy discussions and maintaining their legitimacy within scientific and policy communities. They also show an increasing political sophistication among scientists in the Bay- Delta as they have continued to engage in the policy process and an expanding scale of engagement, from working directly with the policy community to communicating about Bay- Delta ecology and policy with the general public. These approaches, while different, complement each other, demonstrating how scientists can communicate their research in a variety of ways depending on their relationship to the policy community.<br>by Erica Simmons.<br>M.C.P.

This thesis is based on 31 interviews and one focus group conducted with Jewish bisexual women and men in the San Francisco Bay Area. While there is much academic discussion and theory about interlocking oppressions of race, class, gender, and sexuality, I explore the complex ways that these systems weave together with religious and ethnic identification in the lives and speech of study participants. Interviewees discuss their multiple and shifting identities, difficulties that they encounter in conceptualizing the intersection of their ethnicity, religion and sexual orientation, and demonstrate the ways that these identifications intermingle in their speech and stories in spite of these difficulties. They compare the liminal status of both Jewish and bisexual identifications on the boundary of privilege, and their decisions about passing or acting in solidarity with the oppressed.

Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2001.<br>Includes bibliographical references (leaves [108]-[111]).<br>Microenterprise has recently received significant public attention and support as an economic development and poverty alleviation strategy in the United States. Considering the economic, social and professional benefits of microenterprise, self-employment will continue to be pursued by many lower-income women in the future. This study explores the role of barriers in the development and success of lower-income women's business ownership. Through a survey and in-depth interviews with clients of Women's Initiative for Self-Employment, a microenterprise program in San Francisco California, and interviews with microenterprise professionals, barriers to self-employment are identified and discussed. Barriers in question include lack of capital, training and technical assistance, lack of support from family and friends, childcare and transportation, in addition to others identified by the study sample. Special attention is given to the role of housing as a barrier to self-employment for lower-income women. Recommendations to address these barriers to lower-income entrepreneurs are presented.<br>by Meghan Elizabeth Horl.<br>M.C.P.

Full textAbstract:
While there are many proposals for fixing congestion between San Francisco and Oakland in California by adding a new bridge or tube, these solutions will take decades to implement even though a solution is needed now. This thesis assesses sixteen different strategies for reducing congestion in the short-term in the four categories of improving transit, promoting carpooling, implementing intelligent transportation systems practices, and incentivizing alternatives to using the Bay Bridge. Top priorities include HOV improvements on the West Grand Avenue and Powell Street onramps, altering WestCAT Lynx and BART transit services, partnering with rideshare apps to increase transit station accessibility (last mile problem), partnering with vanpool/minibus apps, promoting carpooling and implementing a citizen report system for carpool violators, shifting corporate cultures away from requiring employees to drive and drive alone, and lastly, altering land-use planning practices. To reach this conclusion, an inventory of current proposals and relevant research was compiled. Ridership and capacity data for the various modes of transportation across the bay were assessed for shortfalls and opportunities. Through this research and its resultant conclusions, focus can be placed on the best strategies to pursue in the near-term, while the Bay Area waits on a second bridge or tube in the long-term.

Full textAbstract:
Planning and regulatory environmental agency San Francisco Bay Conservation and Development Commission (BCDC) plays an important role in the permitting of development around the San Francisco Bay. As the agency works to add an environmental justice amendment to its primary policy document, this research explores the S.F. Bay Area’s history of approved development project proposal permits, and the associated patterns of land use and environmental justice implications in order to support the proposed change in permitting policy. By classifying all major permits found within BCDC’s internal permit database into groups based on the type of land use associated with the permit project, i.e. Industrial, Flood Control, Ports, etc., it was possible to create maps showing the geographic distribution of each group of permits. To analyze potential environmental justice implications of the patterns of geographic distribution of development permits, each group of permit types was layered on top of spatial data representing areas around the SF Bay that have been identified as highly socially vulnerable. Based on the findings of this project, it appears that highly socially vulnerable communities around the San Francisco Bay bear a disproportionate amount of land-use related environmental burdens. Furthermore, it is crucial to recognize the limitations of geospatial analysis tools in conveying the magnitude of disproportionate environmental and community health impacts of land use on socially vulnerable communities in the San Francisco Bay Area.

Full textAbstract:
Using cluster analysis, a total of 605 vents in San Francisco Volcanic Field are studied over an area of approximately 5000km2. Application of alignment analysis techniques, including the two-point azimuth analysis and Hough transform analysis, demonstrates that cinder cones are aligned along common orientations within larger clusters. These alignments consist of 9-10 cinder cones, are 20-38 km long, and are regional features. The vent alignments indicate the presence of geological features along which magma ascended more readily than elsewhere. The NE-trending Mesa Butte and Oak Creek Canyon-Doney fault systems seem to control the intermediate to silicic centers which are on the intersection of these fault systems with Cataract Creek fault system and affect the development of cinder cone alignments. Geological maps and geophysical surveys indicate that most vent alignments are parallel or subparallel to these large scale fault systems. This suggests that vent alignment patterns are controlled by regional structures.

Full textAbstract:
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.

Full textAbstract:
<p>Aquatic environments adjacent to industrialized urban centers typically contain anthropogenic chemicals that may cause disruption of endocrine systems and physiological functions. This study investigated whether sites within San Francisco Bay are associated with endocrine disruption in the indigenous fish, shiner perch. The endocrine system that produces cortisol was tested, since it is critical for physiological regulation of stress response, metabolism, immune function and osmoregulation. The cortisol-producing tissue, the interrenal, was also investigated using proteomics technologies to initiate a process of identifying proteins with altered expression and which may therefore be involved in tissue dysfunction. Disrupted cortisol responses were detected in fish from several locations and they were related to certain kinds of contaminants and to changed expression of at least four interrenal proteins, which include heat shock protein 1, transferrin, calreticulin, and calmodulin. Several interrenal proteins were also newly identified. The approaches used herein have strong prospects as bioanalytical screening methodologies in environmental studies. </p>

Full textAbstract:
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 Âbuffer 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.

Full textAbstract:
The practice of gleaning began as a way for the poor to provide sustenance for themselves and their families. Changes in societal ideas about private property as well as a shift toward a neoliberal style of governance have caused gleaning to become what it is today: a practice primarily undertaken by charitable organizations, nonprofits, and church groups who then donate their bounty to local food banks, providing fresh produce to the food insecure. In modern society, gleaning is often held up as a single solution to the problems of food insecurity, poor nutrition, and food waste. This thesis complicates that discourse by analyzing the websites of five different San Francisco Bay Area gleaning groups to investigate how they present themselves as fitting into the larger conversation surrounding food charity, health, and food waste. This thesis uses qualitative and quantitative textual analysis to show how the language used on each organization’s website illustrates the organization’s relationship with those three values. Each organization presents itself as fitting into contemporary food recovery discourse in a different way: one focuses primarily on community building; one is looking to expand its model as far as possible; one seeks to be a solution to poor nutrition, food insecurity, and food waste in its community; one provides myriad resources to anyone looking; and one actively embraces the food insecure. The differences among these organizations show the one-dimensionality of the current discourse surrounding gleaning as a single solution to food insecurity, poor nutrition, and food waste. While gleaning can, and does, have value, its focus on the individual’s role in solving food insecurity, poor nutrition, and food waste, as well as its inability to provide long-term solutions, complicates its role in contemporary food recovery.

Previous issue date: 2016-08-24<br>O objetivo desta tese é analisar as relações sociais de troca que se estabelecem entre os
produtores frutícolas dos perímetros federais irrigados do polo Petrolina-Juazeiro, vale do rio
São Francisco, e os agentes dos mercados de frutas frescas. Investigar o modo como essas
relações, operadas a montante e a jusante da cadeia produtiva de frutas se apresentam, que
contextos e estruturas sociais as influenciam e quais as mediações que requerem. O trabalho
realizado permite entender como funcionam esses mercados, de alto grau de individualização
e incertezas, característico do modo de produção capitalista. Para além das explicações da
teoria econômica, o mercado é aqui entendido como um processo histórico de construção
social. A abordagem teórico-metodológica inclui o tema dos sistemas agroalimentares globais
e conceitos da economia das organizações, e tem como base contribuições da sociologia da
agricultura e dos alimentos e da sociologia econômica; conceitos bourdieusianos de campo,
habitus, capitais, poder, hierarquias e interesses, entre outros, são utilizados para compreender
os contextos atuais, a ação das forças estruturantes dos mercados e as mediações requeridas
nas relações sociais de troca comercial. A investigação empírica, por questão de economia de
tempo e de recursos, se concentrou nos dois maiores e mais complexos perímetros federais do
polo, o Nilo Coelho, em Petrolina (PE) e o Maniçoba, em Juazeiro (BA), cujos ocupantes
foram selecionados e tomados como representativos do universo pesquisado. A metodologia,
predominantemente qualitativa, integra diferentes técnicas de pesquisa, inclusive
quantitativas, como a aplicação de análise de survey, que serviu para atualizar os dados
relativos aos grupos de fruticultores que exploram os denominados lotes de colonos. As
entrevistas semiestruturadas foram trabalhadas com o recurso da análise de conteúdo. Os
resultados obtidos respondem às hipóteses da pesquisa, revelando um longo processo de
construção social, globalizado e com alto grau de incerteza e riscos, a exigir a coordenação de
múltiplos fatores. Como demonstrado neste estudo, as relações sociais de troca comercial
estão submetidas a influências diversas, que as promovem ou as constrangem, vindas do
próprio contexto e de estruturas sociais formadas ao longo de seu desenvolvimento histórico..
O estudo identificou, a partir dos relatos, valiosas oportunidades para a produção de frutas
frescas, que estimulam o protagonismo de seus agentes – se bem que não acessíveis para
todos -, dadas por características da natureza e da cultura, destacando-se a particularidade do
clima; a existência de redes sociais eficientes no acesso aos mercados e ao conhecimento,
arranjos institucionais ainda favoráveis à produção e uma disposição empresarial que parece
dar sentido à vida. Isto nada obstante, foram relatadas ameaças conjunturais e estruturais à
competitividade, vindas, por exemplo, da iminência de crises do abastecimento hídrico, de
contingências climáticas e econômicas, dos custos crescentes e das estratégias comerciais de
competidores internacionais. Para lidar com as incertezas desse contexto, os agricultores
lançam mão, em suas interações de troca comercial, de relações pessoais baseadas em valores
morais, em práticas que se revelam, para além dos preços, como fatores de coordenação
desses mercados.<br>The aim of this thesis is to analyse the social relationships of trading that are established
among fruit producers of irrigated federal perimeters of the pole Petrolina-Juazeiro in the San
Francisco Valley and the agents of fresh fruit markets. It is investigated how these
relationships operated at the input and the processing subsystems of agribusiness of the
productive chain of fruits are presented, what contexts and social structures influence them
and what mediations are required. The work done allows the understanding of how these
markets function, of the high degree of individualization and of uncertainty, distinctive of the
capitalist means of production. Beyond the theoretical-economical explanations, the market,
before mentioned, is here understood as a historical process of social construction. The
theorethic-methodological approach includes the theme of global agrifood systems and
concepts of economy of organizations and it has as a basis contributions of sociology of
agriculture and food, and of economic sociology; Bourdieu‟s own concepts of field, habitus,
power, hierarchies and dispute of interests, among others, are utilized to comprehend the
nowaday contexts, the action of structuring forces on the markets and the mediations needed
in the social relationships of commercial trading. This empirical investigation, due to
economy of time and resources, was concentrated in the two biggest and most complex
federal perimeters: Nilo Coelho in Petrolina, Pernambuco and Maniçoba in Juazeiro, Bahia
whose inhabitants were selected and considered as representatives of the universe studied.
The methodology, predominantly qualitative, is composed of different research techniques,
including quantitative ones, such as application of analyses of survey that aided in describing
the group of fruit growers that exploit the so-called lots of settlers with up-dated data from the
agents. The semi-structured interviews used the analysis of content method. The results
obtained answered to the hypothesis of the research revealing a long process of social
construction that implicates, today, on a mercantile, intensive and globalized context with a
high degree of uncertitudes and risks, demanding the coordination of multiple factors. As it is
shown in this study, the social relations of commercial trading are submitted to diverse
influences that promote or downplay them and are originated from the own context and social
structures formed during their historical development.. The study identified, from reports,
valuable opportunities to the production of fresh fruit that stimulate the protagonism of their
agents – but not accessible to all of them - formed by distinction of nature and of culture,
highlighting weather particularities, the existence of efficient social networks to access
markets and knowledge, institutional procedures still favorable to production and an
entrepreneurial mentality that seems to give life a meaning. Nevertheless it all, conjunct and
structural threats to competiveness were related, coming from, for instance, the imminent
possibility of collapse of water supply, of climate and economic contingencies, of growing
costs and of commercial strategies of international competitors. To deal with the uncertainties
of this context, the farmers use, in their commercial interactions, personal relations based on
moral values in practices that relent the prices as coordinate factors of these markets.

Full textAbstract:
In this study I examined geographic variation in morphology and genetic population structure in
five putative subspecies of song sparrows (Melospiza melodia) in the San Francisco Bay region
(M. m. samuelis, M. m. maxillaris, M. m. pusillula, M. m. gouldii, and M. m. heermanni). My
first goal was to describe genetic population structure at microsatellite loci to assist with
conservation and management strategies for song sparrow populations in the San Francisco Bay
Area. I sampled nine populations from five putative subspecies and found low estimates of
differentiation between populations within subspecies (Fst analog: Φsc = 0.0122, p<0.0001, Rst
analog Φsc = 0.00433, p=0.05963) and between subspecies (Fst analog: Φct = 0.0137, p =
0.04985, Rst analog Φct = 0.0174, p=0.09873) at microsatellite loci. Despite low estimates of
divergence, genetic structure at the subspecies level was indicated by the larger amount of
variance accounted for by subspecies than populations. I propose a Management Unit (MU)
consisting of the range of M. m. pusillula be prioritized for conservation efforts based on the
larger extent of genetic divergence shown by Cavalli-Sforza and Edward's chord distance and
topology of the unweighted pair group cluster analysis which displayed 100% support of
bootstrap replicates across loci. Additionally, I propose the ranges of M. m. samuelis and M. m.
maxillaris be designated an M U despite low differentiation from M. m. heermanni, because it
remains possible that adaptive differences between these types were not identified with neutral
loci. The second goal of this study was to compare morphological and genetic estimates of
divergence in order to evaluate previous hypotheses proposed for differentiation. Fourteen
populations were included in a multivariate analysis of morphological traits and compared with
the genetic differentiation derived from microsatellite loci analysis in Chapter 1. In contrast to
the low genetic differentiation at microsatellite loci, morphological differentiation was high
between song sparrow subspecies. Due to the lack of concordance between estimates of
morphological and genetic divergence, selection or phenotypic plasticity in morphology are
implicated as causes for morphological differentiation among song sparrow subspecies. It is
probable that song sparrow subspecies in the San Francisco Bay region are recently diverged or
have high current gene flow and, therefore, that the rate of evolution at morphological traits
(assuming a heritable basis for those traits) is faster than at neutral loci.

Full textAbstract:
This dissertation focuses on the relationship between accessibility to job opportunities, travel mode choices and employment outcomes of the disadvantaged. In past research examining the impact of accessibility on employment outcomes of the underprivileged, it has been an implicit assumption that a poor individual's employment status is directly connected to accessibility to transport modes and job opportunities. This dissertation challenges such a fundamental assumption and argues that due to unique travel needs of the poor, a high level of access to transportation means or job accessibility provided by a given travel mode does not automatically determine the choice of that particular travel mode. What is missing in the existing literature is examination of how accessibility affects travel mode choices for low-income individuals, and how travel mode preferences subsequently influence their employment outcomes. The objective of this dissertation is to shed new light on current understanding of the relationship between transportation and employment of the disadvantaged. The study focuses on explaining what factors influence low-income individuals in their choice of a transportation mode, and more importantly, how modal preferences, along with job accessibility, affect employment of the poor. Household travel survey data from the San Francisco Bay Area and the Atlanta Metropolitan Region were used to examine this interrelationship. The research findings show that higher modal and job accessibility do not always determine the choice of a particular travel mode, defying the assumption of the previous studies. What is important for enhancing one's employment is whether or not a low-income person has regular access to cars and an individual circumstance allows the poor to utilize existing automobiles rather than the efficiency of highway network. In terms of public transportation, higher job accessibility by transit network is associated with better employment outcomes for transit users. Nonetheless, when transit riders had to access transit systems by walking, job accessibility did not have meaningful impact on employment. It is important to note that the impact that job accessibility by transit has on employment is found only in a transit-friendly Bay Area.

Full textAbstract:
This dissertation studies the history of philanthropy in the San Francisco Bay Area between the 1940s to the 2010s through the experiences of the foundation managers, professors, and attorneys, who collectively oversaw the distribution of philanthropic wealth for the region’s donors. This dissertation argues that foundation managers and a range of other non-donor professionals were critical to the formation of organized philanthropy in the San Francisco Bay Area since the 1940s, which in limited but vital ways redistributed wealth to organizations that provided social welfare services.
In the austere decades of the late 20th century, however, philanthropic intermediaries created new models of giving that, in appealing to affluent people, narrowed the purpose and reach of foundations, while expanding the ability of donors to set conditions on their giving. In tandem with larger political and economic changes, the disruption of philanthropy in the San Francisco Bay Area—the creation of donor-centric modes of giving that appealed to the norms of high-tech and financial moguls—helped produce a local nonprofit sector more reflective of the interests of wealthy donors rather than those in need.
