    Distance communication transfer of HIV prevention interventions to service providers (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-09-28
    Description: Most acquired immunodeficiency syndrome (AIDS) service providers are in countries with little access to scientific developments relevant to their programs. It is critical to transfer advances from the scientific arena to service providers on a global scale. Human immunodeficiency virus (HIV) prevention organizations in 78 countries were randomized to receive either a control condition or a technology transfer condition with an interactive distance learning computer training curriculum and individualized distance consultation. Of 42 nongovernmental organizations in the technology transfer condition, 29 adopted the science-based program in their communities or trained other agencies to also use it. Advanced communication technologies can create a cost-effective infrastructure to disseminate new intervention models to service providers worldwide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, Jeffrey A -- Somlai, Anton M -- Benotsch, Eric G -- McAuliffe, Timothy L -- Amirkhanian, Yuri A -- Brown, Kevin D -- Stevenson, L Yvonne -- Fernandez, M Isa -- Sitzler, Cheryl -- Gore-Felton, Cheryl -- Pinkerton, Steven D -- Weinhardt, Lance S -- Opgenorth, Karen M -- P30-MH52776/MH/NIMH NIH HHS/ -- R01-MH62982/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2004 Sep 24;305(5692):1953-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for AIDS Intervention Research (CAIR), Department of Psychiatry and Behavioral Medicine, Medical College of Wisconsin, Milwaukee, WI 53226, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15448268" target="_blank"〉PubMed〈/a〉

    Generic indicators for loss of resilience before a tipping point leading to population collapse (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-02
    Description: Theory predicts that the approach of catastrophic thresholds in natural systems (e.g., ecosystems, the climate) may result in an increasingly slow recovery from small perturbations, a phenomenon called critical slowing down. We used replicate laboratory populations of the budding yeast Saccharomyces cerevisiae for direct observation of critical slowing down before population collapse. We mapped the bifurcation diagram experimentally and found that the populations became more vulnerable to disturbance closer to the tipping point. Fluctuations of population density increased in size and duration near the tipping point, in agreement with the theory. Our results suggest that indicators of critical slowing down can provide advance warning of catastrophic thresholds and loss of resilience in a variety of dynamical systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dai, Lei -- Vorselen, Daan -- Korolev, Kirill S -- Gore, Jeff -- New York, N.Y. -- Science. 2012 Jun 1;336(6085):1175-7. doi: 10.1126/science.1219805.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22654061" target="_blank"〉PubMed〈/a〉
