    Abstract:

    Author(s): Wang, Y; Zhang, R; Zheng, Q; Deng, Y; Van Nostrand, JD; Zhou, J; Jiao, N | Abstract: © International Council for the Exploration of the Sea 2015. Ocean acidification (OA), caused by seawater CO2 uptake, has significant impacts on marine calcifying organisms and phototrophs. However, the response of bacterial communities, who play a crucial role in marine biogeochemical cycling, to OA is still not well understood. Previous studies have shown that the diversity and structure of microbial communities change undeterminably with elevated pCO2. Here, novel phylogenetic molecular ecological networks (pMENs) were employed to investigate the interactions of native bacterial communities in response to OA in the Arctic Ocean through a mesocosm experiment. The pMENs results were in line with the null hypothesis that elevated pCO2/pH does not affect biogeochemistry processes. The number of nodes within the pMENs and the connectivity of the bacterial communities were similar, despite increased pCO2 concentrations. Our results indicate that elevated pCO2 did not significantly affect microbial Community structure and succession in the Arctic Ocean, suggesting bacterioplankton Community Resilience to elevated pCO2. The competitive interactions among the native bacterioplankton, as well as the modular Community structure, may contribute to this Resilience. This pMENs-based investigation of the interactions among microbial Community members at different pCO2 concentrations provides a new insight into our understanding of how OA affects the microbial Community.

  • developing a tabletop exercise to test Community Resilience lessons from the los angeles county Community disaster Resilience project
    Disaster Medicine and Public Health Preparedness, 2015
    Co-Authors: Anita Chandra, Malcolm V Williams, Christian Lopez, Jennifer Tang, David Eisenman, Aizita Magana
    Abstract:

    OBJECTIVE: We aimed to develop and test a Community Resilience tabletop exercise to assess progress in Community Resilience and to provide an opportunity for quality improvement and capacity building. METHODS: A tabletop exercise was developed for the Los Angeles County Community Disaster Resilience (LACCDR) project by using an extended heat wave scenario with health and infrastructure consequences. The tabletop was administered to preparedness only (control) and Resilience (intervention) coalitions during the summer of 2014. Each exercise lasted approximately 2 hours. The coalitions and LACCDR study team members independently rated each exercise to assess 4 Resilience levers (partnership, engagement, self-sufficiency, and education). Resilience coalitions received more detailed feedback in the form of recommendations for improvement. RESULTS: The Resilience coalitions performed the same or better than the preparedness coalitions on the partnership and self-sufficiency levers. Most coalitions did not have enough (both quantity and type) of the partner organizations needed for an escalating heat wave or changing conditions or enough engagement of organizations representing at-risk populations. Coalitions also lacked educational materials to cover topics as far ranging as heat to power outages to psychological impacts of disaster. CONCLUSION: A tabletop exercise can be used to stress and test Resilience-based capacities, with particular attention to a Community's ability to leverage a range of partnerships and other assets to confront a slowly evolving but multifactorial emergency.

  • partnerships for Community Resilience perspectives from the los angeles county Community disaster Resilience project
    Public Health, 2015
    Co-Authors: Gloria C Chi, Anita Chandra, Malcolm V Williams, Alonzo L Plough, David Eisenman
    Abstract:

    Community partnerships are critical to public health practice in general,1 and in particular to local health department programs to improve emergency preparedness and Community Resilience.2 Greater integration of organizations can build trust and increase participation in emergency preparedness activities that increase knowledge and contribute to enhanced preparedness and recovery plans.3 By creating well-functioning partnerships across organizations, health departments can also pool together a diverse set of resources to enhance their preparation for, response to, and recovery from a disaster or emergency.3,4 To facilitate building such relationships, the Centers for Disease Control and Prevention (CDC) identified 11 Community sectors with which local health departments may consider developing partnerships. These sectors include businesses, Community leadership, cultural and faith-based groups and organizations, emergency management, health care, social services, housing and sheltering, media, mental/behavioral health, organizations serving the interests of at-risk populations such as older persons, and education and childcare.2 In 2011, the Los Angeles County Department of Public Health created the Los Angeles County Community Disaster Resilience initiative to develop strategies and enhance partnerships towards building Community Resilience.5–7 One goal of this project was to support the department in strengthening partnerships with non-governmental organizations, not simply between the Emergency Preparedness and Response Program that administers the initiative, but also with other department divisions to enhance their integration into Community Resilience development. To capture the baseline for our work, a cross-sectional survey was administered to a sample of Los Angeles County Department of Public Health staff in 2012. The survey included questions about partnerships with other organizations. The goal of this paper is to describe partnership activities conducted by the Los Angeles County Department of Public Health and the types of organizations that have partnerships with the department. In addition, this paper investigates perceived barriers to partnerships. The survey was administered to Los Angeles County Department of Public Health staff from October, 2012 to December, 2012. Potential respondents included a sample of various levels of staff within each program in the department that included representation from program directors or managers, analysts, and administrative staff. The sample was also selected proportional to the size of the program so there was greater representation from the three largest programs: Acute Communicable Disease Control, Community Health Services, and the Emergency Preparedness and Response Program. Potential respondents were invited to participate via email and were asked to fill out the survey online (LimeSurvey8). Three reminder emails were sent to respondents over the survey period. The survey was administered by collaborators at the RAND Corporation. The survey included several categories of questions, including respondents' programs within the department, roles within the programs, challenges in building partnerships, current partnerships, and activities conducted with partners. The survey instrument was pilot tested with five Los Angeles County Department of Public Health respondents to assess readability and flow and to determine if the questions were interpreted as intended. A total of 262 invitations were sent out and 89 responses received for a response rate of 34.0%. The two largest groups of respondents were program directors and public health nurses, each constituting 22.5% of all respondents. Other respondents included program managers (15.7%), executive administrators (12.4%), physicians (12.4%), health educators (6.7%), analysts/planners (6.7%), administrators (3.4%), and epidemiologists (1.1%). The three largest programs (Acute Communicable Disease Control, Community Health Services, and Emergency Preparedness and Response) accounted for approximately 53% of all respondents.

  • getting actionable about Community Resilience the los angeles county Community disaster Resilience project
    American Journal of Public Health, 2013
    Co-Authors: Anita Chandra, Malcolm V Williams, Alonzo L Plough, Alix Stayton, Kenneth B Wells, Mariana Horta, Jennifer Tang
    Abstract:

    Community Resilience (CR)—ability to withstand and recover from a disaster—is a national policy expectation that challenges health departments to merge disaster preparedness and Community health promotion and to build stronger partnerships with organizations outside government, yet guidance is limited.A baseline survey documented Community Resilience–building barriers and facilitators for health department and Community-based organization (CBO) staff. Questions focused on CBO engagement, government–CBO partnerships, and Community education.Most health department staff and CBO members devoted minimal time to Community disaster preparedness though many serve populations that would benefit. Respondents observed limited CR activities to activate in a disaster. The findings highlighted opportunities for engaging communities in disaster preparedness and informed the development of a Community action plan and toolkit.

  • building Community Resilience to disasters a way forward to enhance national health security
    2011
    Co-Authors: Anita Chandra, Malcolm V Williams, Joie D Acosta, Stefanie Howard, Lori Uscherpines, Douglas Yeung, Jeffrey Garnett, Lisa S Meredith
    Abstract:

    : Community Resilience, or the sustained ability of a Community to withstand and recover from adversity, has become a key policy issue at federal, state, and local levels, including in the National Health Security Strategy. Because resources are limited in the wake of an emergency, it is increasingly recognized that Resilience is critical to a Community's ability to reduce long recovery periods after an emergency. This article shares details of a report that provides a roadmap for federal, state, and local leaders who are developing plans to enhance Community Resilience for health security threats and describes options for building Community Resilience in key areas. Based on findings from a literature review and a series of Community and regional focus groups, the authors provide a definition of Community Resilience in the context of national health security and a set of eight levers and five core components for building Resilience. They then describe suggested activities that communities are pursuing and may want to strengthen for Community Resilience, and they identify challenges to implementation.

  • Community Resilience learning collaborative and research network c learn study protocol with participatory planning for a randomized comparative effectiveness trial
    International Journal of Environmental Research and Public Health, 2018
    Co-Authors: Benjamin Springgate, David Eisenman, Armen C Arevian, Ashley Wennerstrom, Arthur Johnson, Olivia K Sugarman, Catherine Haywood, Edward J Trapido, Cathy D Sherbourne, Ashley Everett
    Abstract:

    This manuscript presents the protocol and participatory planning process for implementing the Community Resilience Learning Collaborative and Research Network (C-LEARN) study. C-LEARN is designed to determine how to build a service program and individual client capacity to improve mental health-related quality of life among individuals at risk for depression, with exposure to social risk factors or concerns about environmental hazards in areas of Southern Louisiana at risk for events such as hurricanes and storms. The study uses a Community Partnered Participatory Research (CPPR) framework to incorporate Community priorities into study design and implementation. The first phase of C-LEARN is assessment of Community priorities, assets, and opportunities for building Resilience through key informant interviews and Community agency outreach. Findings from this phase will inform the implementation of a two-level (program-level and individual client level) randomized study in up to four South Louisiana communities. Within communities, health and social-Community service programs will be randomized to Community Engagement and Planning (CEP) for multi-sector coalition support or Technical Assistance (TA) for individual program support to implement evidence-based and Community-prioritized intervention toolkits, including an expanded version of depression collaborative care and resources (referrals, manuals) to address social risk factors such as financial or housing instability and for a Community Resilience approach to disaster preparedness and response. Within each arm, the study will randomize individual adult clients to one of two mobile applications that provide informational resources on services for depression, social risk factors, and disaster response or also provide psychoeducation on Cognitive Behavioral Therapy to enhance coping with stress and mood. Planned data collection includes baseline, six-month and brief monthly surveys for clients, and baseline and 12-month surveys for administrators and staff.
