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. Policy implication from this dissertation is discussed. / text

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.

Through ethnography, I examine how hip-hop’s expressive forms are being used as the raw materials of everyday life by residents of the San Francisco Bay Area, home to what many regard as one of the most stylistically prolific, politically charged, and racially diverse hip-hop “scenes” in the world. This focus on regional specificity provides a greater understanding of the impact hip-hop is having on the ground, as an aspect of localized lived practice. Throughout, I make the case for the importance of ethnographically grounded localized research on U.S. hip-hop, which is surprisingly still relatively rare. Most scholars simply stress its continuity within a set of deterritorialized Diasporic African and African-American verbal-art traditions. My aim is not to contest this assertion, but to add to the body of knowledge about one of the most significant cultural inventions of the twentieth century by exploring hip-hop’s racial heterogeneity and its regional specificity. Acknowledging this kind of diversity allows us to reconceive what hip-hop is and how it matters in U.S. society beyond the ways it is usually framed: as either an oppositional form of black-vernacular culture or a co-opted and corrupted commodity form that reinscribes hegemonic values more than it actually contests them. Examining hip-hop within a specific, regionally delineated community reveals how hip-hop’s role in American life is more nuanced and complex. It is neither a pure vernacular expression of an oppressed class nor merely a cultural commodity imposed upon consumers and alienated from producers. In the Bay Area, hip-hop “heads” simultaneously consume mass-produced rap while producing homespun forms of music, dance, slang, fashion, and folklore. Through these forms, they construct individual and group identities that register primarily in expressive, affective terms. These novel cultural identities complicate rigid social markers of race, gender, and class; more specifically, they challenge the widely held perception that hip-hop is solely the terrain of inner-city young African-American men. More fundamentally, a sense of belonging is engendered through localized modes of expression and embodied style that manifest through shared practices, discourses, texts, symbols, locales, and imaginaries. / text

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 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.

舊金山是美國北加州的重要城市，亦是俄裔移民群居的重要據點。俄裔人口18世紀隨著帝國東擴到達北美洲，他們在北美設立眾多據點進行開墾及貿易。直至19世紀中葉俄國退出北美勢力後，俄裔移民仍在北美延續其文化影響。隨著廿世紀四波移民潮的相繼湧入，舊金山灣區的俄裔移民呈現多元文化發展，城市內的小俄羅斯牽繫著俄裔移民的情感。 俄裔移民在不同時期移民美國，他們主因家庭團聚及經濟因素遷移至舊金山灣區。本文主要探討文化傳承中的四個面向：語言、宗教、飲食及節慶，俄裔移民在舊金山灣區的文化傳承現況如下：俄語傳承主要在家中及學校習得、宗教信仰觀念受移民成長環境意識形態之影響而異、飲食習性因便利性與烹飪習慣呈現兩極化、俄羅斯節對於凝聚俄裔移民及推廣俄羅斯文化具重大傳承意義。 / San Francisco, not only the important city of North California, but also home to many Russian-Americans. Russians first reached North America back in the 18th century with the expansion eastward of the Russian Empire. They set up numerous settlements to develop trade in the new continent until mid-19th century. After the end of Russian America, the cultural influence of Russia still last to date. Along with the four waves of Russian immigrants, Russian culture in San Francisco has developed diversely. Despite Russian immigrants migrated to America in different time periods, family reunion and economic consideration has been the main cause. Cultural heritage discussed in this thesis includes language use, religion, cuisine and festival.
