Academic literature on the topic 'San Francisco Pilot Project, 1970'

Project LINK (A Live and Interactive Network of Knowledge), is a collaboration of Eureka Scientific, Inc., the San Francisco exploratorium Science Museum, and NASA/Ames Research Center. Project LINK has demonstrated video-conferencing capabilities from the Kuiper Airborne Observatory (KAO) to the San Francisco Exploratorium in the context of science education outreach to K-12 teachers and students. The project was intended to pilot-test strategies for facilitating the live interface between scientists and K-12 teachers aboard the KAO with their peers and students through the resources and technical expertise available at science museums and private industry. The interface was based on Internet/macintosh video conferencing capabilities which allowed teachers and students at the Exploratorium to collaborate in a live and interactive manner with teachers and scientists aboard the KAO. The teachers teams chosen for the on-board experiments represented rural and urban school districts in California. The teachers interfaced with colleagues as part of the NASA-Funded Project FOSTER (Flight Opportunities for Science Teacher Enrichment).

Abstract Numerous investigations of time-space clustering in Hodgkin's disease, designed to investigate its communicability, have produced equivocal results. Few studies have considered the spatial clustering reflecting a broader range of exposures despite sporadic evidence of such groupings of Hodgkin's disease cases. This project examined spatial (residential) patterns among 741 white Hodgkin's disease cases from the San Francisco-Oakland, California, area using 1969–1977 cancer registry incidence data and 1970 population counts. Two types of distances between cases were evaluated using new statistical methods that adjust for population density. Hodgkin's disease cases lived closer to their nearest case neighbors than expected in four of five study counties. Significant clustering of this type occurred among case subgroups defined by sex, age, and social class. There was little evidence of larger-scale clustering around a single point-source exposure. The small, widely dispersed clusters detected here suggest late exposure to a ubiquitous environmental agent involved in Hodgkin's disease etiology. These case aggregations are consistent both with prior reports of spatial clustering in this lymphoma and with evidence implicating viral or other factors in its pathogenesis.

Resumo: Este texto analisa dois filmes produzidos em bitola super-8 como linguagem documental no trabalho do fotógrafo e poeta baiano Euvaldo Macedo Filho, no final dos anos 1970, no Estado da Bahia, Brasil. Inicialmente, trazemos à discussão um recorte de imagens que circulavam à época e que eram usadas na visualização das práticas sociais que estavam transformando os espaços do rio São Francisco, especialmente a navegação. Em seguida, problematizamos a construção de dois artefatos fílmicos a partir da opção tecnológica e da inserção do olhar documental de seu realizador nas questões sociais daquele momento. As imagens em super-8 analisadas compunham um projeto deliberado de memória e de crítica dos eventos, constituindo-se ponto dialético de observação da sociedade.Resumen: En este texto se analizan dos películas producidas en formato super-8, realizadas en la década de 1970 como lenguaje documental por el fotógrafo y poeta brasileño Euvaldo Macedo Filho, nacido en el estado de Bahía.

At first, the discussion focus on the images circulating during that period, which were used on the display of social practices, changing spaces of Sao Francisco river, mainly at navigation. Moreover, the construction of two short movies is problematize through the technology practices of the artist and the insertion of his documental regard at the social issues of its moment. These images were part of an intentional project of memory and social criticism of events, turning themselves into a dialectical point for society observation.

R.G. Davis founded the company that became the San Francisco Mime Troupe as an experimental project of the Actors' Workshop in 1959. He left the Troupe in 1970, formed the Epic West Center in Berkeley for the study of Bertolt Brecht and epic theatre, and became a pioneering director in the United States successively of the plays of Brecht and Dario Fo, on which he wrote in the original Theatre Quarterly 40 (Autumn–Winter 1981) and in New Theatre Quarterly 8 (November 1986). In this article he traces the course of his subsequent career in creating experimental storytelling events and, via an interlude garnering academic qualifications, into the field of ecological aesthetics, which he defines as ‘a Brechtian aesthetic and ecological socialism interrogating each other within a scientific ecological conception of nature’. The present article is based on a lecture he gave in June 2013 at Stanford University.

Abstract The historical lack of outcomes-related data in Adult Protective Services (APS) has affected funding coming to the program. Without data quantifying the effectiveness of APS services, policymakers have been unable to justify budget increases to improve wages for workers or professionalize the field. For the first time in APS history, the U.S. Administration for Community Living sponsored a pilot project to implement a novel evidence-based assessment tool into APS electronic systems, called the Identification, Services, and Outcomes (ISO) Matrix. The goal was to improve APS’ ability to reduce harm of abuse and neglect and maintain client’s independence to live in the community. APS workers in San Francisco and Napa Counties were trained and phased into using the ISO Matrix over a six-month implementation period. This poster presents findings from six focus groups conducted between February 13 and March 28, 2019, with 34 San Francisco and Napa County APS workers and supervisors. Utilizing semi-structured, in-depth interviewing techniques, APS workers and supervisors expressed their views and experiences. Facilitators and barriers of implementing the ISO Matrix were assessed and opportunities for improvements were identified. Findings revealed a tension between their hopefulness that the ISO Matrix could modernize APS data-tracking and yield evidence of improved client outcome to bolster the field, and their frustrations about new burdens the ISO Matrix placed on their labor and workflow. Understanding frontline perspectives of APS workers and supervisors has practical and policy implications for adopting the ISO Matrix in other counties and states across the U.S.

Summary A steam injection project was conducted in diatomite containing heavy, biodegraded oil (12°API, ?3,000 cp) in the South Belridge field, Kern County, California. The diatomite interval tested (the San Joaquin, Etchegoin, and Belridge diatomites) underlies an active steamflood in the sandstone of the Tulare formation. Initially, the test was to determine the viability of cyclic steam recovery from an unpropped, steam fractured completion in the diatomite. Four standard steam cycles were completed, with sluggish oil recovery [oil-steam ratios (OSR) were less than 0.1]. The well was then hydraulically fractured and propped. Two additional steam cycles were completed that had considerably greater oil recovery (OSR>0.2). The project was then configured for steamdrive by drilling a closely spaced producer. The new producer was initially completed with a propped hydraulic fracture and cycled once. The original cyclic producer was converted to continuous injection, and a two-well steamflood was operated for more than 1 year. During the steamflood, heavy oil was mobilized and response has been continuous. The configuration of the "pattern," with only one producer, results in poor capture efficiency. The performance of this incomplete pattern has been, as expected, poor (<0.1 OSR), but steam injection is shown to be a promising recovery technique for the heavy oil diatomite. The process is applicable to California diatomites, or any other high porosity, low permeability, shallow reservoirs that contain a significant concentration of heavy oil. Introduction It is estimated that the diatomite in the San Joaquin Valley of California contains as much as 10 billion barrels of oil. Mobil's former holdings in South Belridge, Lost Hills, and McKittrick, now part of Aera Energy, a joint venture between Mobil and Shell, contain on the order of 1 to 2 billion barrels. These formations are marked by high porosity (40 to 70%) and moderate to high oil saturation that can result in very high oil concentrations that are amenable to such recovery techniques as steam injection. The low permeability of diatomite (generally <1 md), however, makes any recovery technique very challenging. The diatomaceous facies of the Monterey formation is widespread along the western and central portion of the San Joaquin Valley and is one of the reservoir intervals for commercial production from the Lost Hills, South Belridge, McKittrick, Midway-Sunset, and Buena Vista fields. In some of these fields, such as South Belridge, productive diatomite reservoirs directly underlie highly productive massive steamflood operations in sandstones of the Tulare formation. These thick diatomite strata (up to 1,000 ft) form an attractive target and, in some respects, represent the final frontier for thermal recovery operations in onshore California. Especially attractive, if thermal operations can be utilized to unlock the diatomite, is the existing steamflood infrastructure available for the diatomite, particularly as conventional operations (such as the Tulare) decline sharply. South Belridge could certainly benefit from such a synergistic implementation. The South Belridge diatomite reservoir exhibits considerable areal and vertical variation in oil properties. In the central and southeastern portions of what were Mobil's properties, the upper portion of the diatomite reservoir contains heavy, biodegraded oil, the kind found in the overlying Tulare. Below this, the oil grades to intermediate and light. Further complicating the description is the mineralogy: the highly porous Opal A lies in the shallower depths, but has changed, due to increased temperature accompanying burial, from amorphous opaline silica to the less porous, more mechanically competent Opal CT. In South Belridge, Mobil had primary recovery operations for light oil in both the Opals A and CT, and waterflood operations in light (overlapping into the intermediate) oil in the Opal A. All wells for these operations are hydraulically fractured, a technique that opened the way in the late 1970's for accelerated development of the diatomite reservoirs in the San Joaquin Valley.1 Even so, the ultimate expected recovery is small (<20%, even for waterflood). Currently, Aera has no commercial operations in the heavy oil diatomite. Heavy and intermediate oil, at least for the former Mobil portion of South Belridge, represent a significant fraction of the total holdings. Commercial cyclic steam operations have been ongoing by Union, Chevron,2 and Texaco in the McKittrick field and pilot operations for cyclic and steamflood have been initiated by Cal Resources and Mobil (now combined as Aera Energy) in the South Belridge field.3–9 During the late 1980's, Mobil had several isolated field trials of cyclic steam injection in wells hydraulically fractured and propped in intervals containing either heavy or intermediate oil. These tests paved the way for our first intensive pilot to determine the feasibility of thermal operations in the heavy oil diatomite at South Belridge. Previous thermal pilots in the diatomite for heavy oil have utilized cyclic steam. The only previous pilot for steamflooding,3–9 also in the South Belridge, targeted a light oil interval. This pilot therefore represents the first cyclic steam followed by steamflooding for a heavy oil interval in the California diatomite. An additional area for concern to be addressed in this thermal pilot was how steam injection would affect the problematic subsidence in the diatomite10,11 and potential wellbore failures.12,13 Original Purposes of the Test. The initial purpose of the test was to determine the viability of high pressure steam injection into an unfractured interval of diatomite in the South Belridge containing heavy oil. The test had the following original objectives:quantify incremental oil production attributable to steam stimulation;better define the crude oil gravity and viscosity in the South Belridge diatomite;confirm the laboratory-based predictions of siliceous matrix dissolution and crude distillation resulting from steam injection;determine the feasibility of linkage to the natural fracture system; anddetermine the impact of steam cycling on localized formation compaction.

Background Youth are globally recognized as being vulnerable to HIV. Younger age has been correlated with worse health outcomes. Mobile health (mHealth) interventions have the potential to interact with youth where they are, using a device they already access. Objective Using predefined benchmarks, we sought to evaluate the feasibility and acceptability of WYZ, an mHealth app, for improved engagement in care and antiretroviral therapy (ART) adherence among youth and young adults living with HIV. WYZ was designed and developed with input from youth and young adults living with HIV using a human-centered design approach and was based on the information, motivation, and behavioral skills framework to address common barriers to care and ART adherence among youth and young adults living with HIV. Methods We recruited youth and young adults living with HIV (18-29 years old) from the San Francisco Bay Area to take part in a 6-month pilot trial. Their participation included completing baseline and exit surveys, and participating in seven phone check-ins about their use of WYZ. Results Youth and young adults living with HIV (N=79) reported high levels of feasibility and acceptability with WYZ use. We met predefined benchmarks for recruitment (79/84, 94%), mean logins per week (5.3), tracking ART adherence (5442/9393, 57.9%), posting chat topics per week (4.8), and app crashes reported per week (0.24). The ease of app download, install, and setup, and comfort with security, privacy, and anonymity were highly rated (all over 91%). Additionally, participants reported high satisfaction for a research project that was remotely conducted. Participants used the app for shorter timeframes compared to the predefined benchmark. Conclusions We noted high feasibility and acceptability with WYZ. Further research to examine the efficacy of WYZ will enable youth and young adults living with HIV and their providers to make informed decisions when using, recommending, and prescribing the app for improved engagement in HIV care and ART adherence.

Restoration projects provide a valuable opportunity to experimentally establish foundational habitats in different combinations to test relative effects on community assembly. We evaluated the development of macroinvertebrate communities in response to planting of eelgrass (Zostera marina) and construction of reefs intended to support the Olympia oyster (Ostrea lurida) in the San Francisco Estuary. Plots of each type, alone or interspersed, were established in 2012 in a pilot living shorelines project, and quarterly invertebrate monitoring was conducted for one year prior to restoration, and three years post-restoration using suction sampling and eelgrass shoot collection. Suction sampling revealed that within one year, oyster reefs supported unique invertebrate assemblages as compared to pre-restoration conditions and controls (unmanipulated mudflat). The eelgrass invertebrate assemblage also shifted, becoming intermediate between reefs and controls. Interspersing both types of habitat structure led eelgrass invertebrate communities to more closely resemble those of oyster reefs alone, though the eelgrass assemblage maintained some distinction (primarily by supporting gammarid and caprellid amphipods). Eelgrass shoot collection documented some additional taxa known to benefit eelgrass growth through consumption of epiphytic algae; however, even after three years, restored eelgrass did not establish an assemblage equivalent to natural beds, as the eelgrass sea hare (Phyllaplysia taylori) and eelgrass isopod (Pentidotea resecata) remained absent or very rare. We conclude that the restoration of two structurally complex habitat types within tens of meters maximized the variety of invertebrate assemblages supported, but that close interspersion dampened the separately contributed distinctiveness. In addition, management intervention may be needed to overcome the recruitment limitation of species with important roles in maintaining eelgrass habitat.

IntroductionHIV transmission and acquisition risk among transgender women is particularly high in the context of primary partnerships. This project extends a previous pilot couples-focused HIV intervention programme, which was shown to be feasible, acceptable and promising in reducing sexual risk behaviour among transgender women and their partners. This randomised controlled trial (RCT) tests the efficacy of this culturally sensitive HIV prevention programme for HIV-serodiscordant and HIV-negative seroconcordant transgender women and their partners.Methods and analysisTo finalise the protocol for trial, we used qualitative methods to hone eligibility criteria, refine the intervention and control manuals, and name and brand the intervention (‘It Takes Two’). The RCT investigates the effects of the It Takes Two intervention on Composite Risk for HIV (CR-HIV) among 100 couples. CR-HIV is a binary indicator of couple HIV risk using validated measures of sexual behaviour, pre-exposure prophylaxis use among HIV-negative participants and viral suppression among participants living with HIV. Using a two-arm RCT, we will examine intervention effects on CR-HIV at 12-month follow-up comparing transgender women and their partners randomised to the intervention versus control (HIV prevention information only).Ethics and disseminationThis study has been reviewed and approved by the University of California, San Francisco (19-28624) and the University of Michigan (HUM00147690) Institutional Review Boards. Participants provide informed consent before taking part of the study activities. Results will be published in peer-reviewed journals and presented at scientific conferences. We will make our results available to the community of researchers and general public interested in transgender health to avoid unintentional duplication of research, as well as to others in the health and social services community, including LGBT community-based organisations, AIDS service organisations and other transgender-serving organisations. The full de-identified dataset and codebook will be shared at the University of Michigan Digital Repository.Trial registration numberNCT04067661.

Abstract Introduction American Society for Microbiology, Guidelines for Biosafety in Teaching Laboratories (2012) state that educators must use best practices to minimize risk of biohazard contamination to students. Integrating mobile digital devices into Medical Laboratory Science (MLS) programs’ clinical training is potentially one means of reducing this risk. Historically, student assignments and evaluations for clinical rotations were in paper format. The purpose of this pilot project was to ascertain attitudes from students and clinical educators on using mobile devices as a laboratory bench-side educational tool during clinical rotations. Methods In this prospective study, three senior-level MLS students used Apple iPads (Apple, Inc; Cupertino, CA) in concert with Google Drive (Google; Mountain View, CA) in lieu of paper manuals during Hematology and Transfusion Medicine clinical rotations at Virginia Commonwealth University Health in fall 2018. Two VCUH clinical educators from these laboratories also participated. All participants were trained on usage and access of electronic material on the iPads as well as proper cleaning of the devices. As a comparison, student participants used paper clinical manuals during their Chemistry and Microbiology rotations. In addition, the clinical educators used paper versions of clinical manuals during four of five student rotations that occurred in fall 2018. Prestudy surveys were used to assess attitudes toward mobile devices. Focus groups, for students and clinical educators, separately, were conducted after completion of the clinical rotations. Conclusions The results of the study indicate that advantages of employing mobile devices include improvement of safety by eliminating transfer of paper worksheets from laboratory to the outside, ability to electronically monitor students’ progress through clinical laboratory rotations, and ease of accessibility to electronic references at the bench-side. Moving forward, the study will expand to include additional disciplines and students as well as employment of styli and DocuSign (DocuSign, Inc.; San Francisco, CA).
