A CASE FOR SUSTAINABLE SECURITY SYSTEMS ENGINEERING: INTEGRATING NATIONAL, HUMAN, ENERGY AND ENVIRONMENTAL SECURITY 总被引:1,自引:1,他引:0
Jason K. Levy 《系统科学与系统工程学报(英文版)》2009,18(4):437-460
In the wake of the September 11, 2001 terrorist attacks, there is a growing sense of insecurity felt by many citizens around the world. Sustainable security, with roots in the sustainable development and human security literature, seeks positive transformations for the co-evolving and mutually dependent human-environmental condition by integrating (and subsuming) national, human, environmental, and energy security concerns and capitalizing on opportunities provided by human creativity, diplomatic openings, modernization and environmental change. The field of Sustainable Security Systems Engineering is proposed for protecting, restoring, designing, and implementing a set of integrated natural and man-made processes that equitably and responsibly meet the biophysical needs of human communities, while maintaining long-term security, respecting financial constraints, meeting ecological limits, and improving institutional arrangements for transparent and effective governance. Scenario planning is shown to help promote sustainable security by identifying the preconditions of instability and helping to proactively address them in an increasingly complex and uncertain world. The six papers published in this featured collection cross policy domains, geographic, political, and sectoral boundaries and were discussed at forums sponsored by the Systems Engineering and Global Policy group. Collectively, they demonstrate the quality, breadth and depth of systems engineering methodologies that are used to promote sustainable security. 相似文献

Co-administration of cannabidiol with delta1-tetrahydrocannabinol was found to have no effect on the rate of disappearance of delta1-tetrahydrocannabinol from the blood of rats. The implications of this finding are discussed. 相似文献

Mutations in a Sar1 GTPase of COPII vesicles are associated with lipid absorption disorders 总被引:10,自引:0,他引:10
Jones B Jones EL Bonney SA Patel HN Mensenkamp AR Eichenbaum-Voline S Rudling M Myrdal U Annesi G Naik S Meadows N Quattrone A Islam SA Naoumova RP Angelin B Infante R Levy E Roy CC Freemont PS Scott J Shoulders CC 《Nature genetics》2003,34(1):29-31
Dietary fat is an important source of nutrition. Here we identify eight mutations in SARA2 that are associated with three severe disorders of fat malabsorption. The Sar1 family of proteins initiates the intracellular transport of proteins in COPII (coat protein)-coated vesicles. Our data suggest that chylomicrons, which vastly exceed the size of typical COPII vesicles, are selectively recruited by the COPII machinery for transport through the secretory pathways of the cell. 相似文献

Summary Inoculation of Wistar CF rats with Gross virus induces in 86% of the animals a leukaemia which is associated, in nearly 50% of the cases, with a paralysis of the hind legs.This paralysis is due to the compression of the spinal cord by leukaemic cell infiltrates which develop in the lumbar area. No neurotropic virus has been found in these animals. 相似文献

Halothan anesthesia was found to be hapatotoxic in the rat, as demonstrated by a significant elevation of serum xanthine oxidase (SXO) level. SXO appeared to be more sensitive marker of liver damage than serum glutamic oxalacetic transaminase. SXO was found to be elevated also following exposure to relative hypoxia. 相似文献
