Project Summary/Abstract The Developmental Core will be the backbone of the JH-E-dARC, working across the Research Cores, investigators and users to enhance capacities and opportunities for rigorous engagement and scientific advancement in structural determinants of health research, including stigma and health equity research. Creating capacity building and research opportunities that support the career development and scientific advancement of structural determinants of health research is critical in coming years, because the HIV response increasingly requires attention to closing gaps in access to equitable treatment and prevention outcomes across populations. We must invest now in developing and supporting the next generation of scientists who will lead the science of reaching and serving these communities with interventions and services to improve equity. Through the Developmental Core of the dARC, we will foster a culture of innovation, investigator development and collaboration through activities drawing from our experience of scientific mentorship, technical capacity development and career development support. We will draw upon a team of experts with inter-disciplinary expertise. Specifically, we aim to: Aim 1: Develop a community of practice and technical support to empower the next generation of stigma and structural determinants of health researchers. Activities include a self-paced series of on-demand, short grant development videos that include content specific to stigma and health equity concepts; internal review services for specific aims and coordination of external reviews of grants; manuscript review and support on journal placement, revisions, and increasing visibility and impact; and a seminar symposium series emphasizing career development. Aim 2: Advance the proliferation and dissemination of science in measuring and responding to stigma and structural determinants of HIV among emerging scientists. Bi-annual small grants will be made the Developmental Core, to support new, stigma-related analyses of existing datasets. To bring in investigators new to these topic areas, we will utilize mentorship models within the small grant system. Additionally, dissemination awards to report stigma- related research at relevant conferences will be funded by the Core on a rolling basis to facilitate dissemination and foster networking opportunities for early-stage investigators. Aim 3: Build partnerships with community action groups, service providers and health departments to foster the meaningful engagement of impacted communities in all phases of research. Core will liaise with community groups and representatives to build academic-community partnerships for future grants. This process will improve the significance of grant concepts by ensuring meaningful engagement with community partners and supporting the incorporation of the priorities, ideas and capacities of community partners. Further, Core will support compensation of community pa...
