urban planning in transformation to a interNational metropolis a probe of realize ways to the rational growth of xi an urban space
Urban Studies, 2011Co-Authors: Zhang PeiAbstract:Against the background of economic globalization and regional integration,city religions,with metropolis as the core factor,have become the religional development pattern and space combination form in both global competition and National Strategy.As a response to our National Strategy intention,this paper formulates the content of Xi'an's building up to a interNational metropolis in China by reviewing a large amount of related theories and planning methods.Based on the issue of rational city space development,this paper puts forward space planning policies,optimizes valuation system and reforms system procedure to solve the problems faced with Xi'an in its development to an interNational metropolis by analysising Xi'an's present space development situation and reconstructing its existing space dimension.

addressing the surveillance goal in the National Strategy for suicide prevention the department of defense suicide event report
American Journal of Public Health, 2012Co-Authors: Gregory A Gahm, Mark A Reger, Julie T Kinn, David D Luxton, Nancy A Skopp, Nigel BushAbstract:The US National Strategy for Suicide Prevention (National Strategy) described 11 goals across multiple areas, including suicide surveillance. Consistent with these goals, the Department of Defense (DoD) has engaged aggressively in the area of suicide surveillance.The DoD's population-based surveillance system, the DoD Suicide Event Report (DoDSER) collects information on suicides and suicide attempts for all branches of the military. Data collected includes suicide event details, treatment history, military and psychosocial history, and psychosocial stressors at the time of the event.Lessons learned from the DoDSER program are shared to assist other public health professionals working to address the National Strategy objectives.

the need for a National Strategy to address vector borne disease threats in the united states
Journal of Medical Entomology, 2019Co-Authors: Charles B Beard, Susanna N Visser, Lyle R PetersenAbstract:Vector-borne diseases (VBDs) cause significant morbidity and mortality each year in the United States. Over the last 14 yr, over 700,000 cases of diseases carried by ticks, mosquitoes, and fleas have been reported from U.S. states and territories to the Centers for Disease Control and Prevention. The number of reported cases has been increasing annually with two major trends: a steady increase in tick-borne diseases and increasing intermittent outbreaks of mosquito-borne arboviruses. The factors that are driving VBD introduction and emergence vary among diseases but are not likely to disappear, indicating that current trends will continue and probably worsen in the absence of effective prevention and control tools and implementation capacity. There are a number of challenges to preventing VBDs, including the lack of vaccines and effective vector control tools, insecticide resistance, and eroding technical capacities in public health entomology at federal, state, and local levels. For these reasons, a National Strategy is needed to address VBD threats and to reverse the alarming trend in morbidity and mortality associated with these diseases.

towards a National Strategy to optimise the management of a widespread invasive tree prosopis species mesquite in south africa
Ecosystem services, 2017Co-Authors: Ross T Shackleton, David Le C Maitre, Brian W Van Wilgen, David M RichardsonAbstract:Invasive stands of Prosopis (mesquite) cover over 6 million ha of South Africa and could invade over 56 million ha. These invasive stands have major impacts on biodiversity, local livelihoods and ecosystem services. We applied several methods to develop an objective basis for a National Strategy to prioritise and guide the management of Prosopis. Decision trees were used for assigning different control objectives (prevention of spread to unoccupied areas, local eradication, containment and asset protection) to each of the 234 local municipalities in the country. Priority assets that require protection in densely invaded areas were identified, ranked and mapped (in order of importance: water source areas, biodiversity hotspots, and areas with high agricultural and rangeland potential). Available control methods were compared in terms of costs, effectiveness, and potential to create employment. Biological control and more mechanised approaches were identified as important and the role of control-through-utilisation requires urgent research. Scenario development suggests that integrated control would be most effective. Strategic guidelines for improving the management of Prosopis were produced. These guidelines discuss key needs and objectives for management, targets, time frames, indicators and monitoring programs, research needs and spatially prioritized management areas. Although the Strategy proposed in this paper is specific to Prosopis in South Africa, the principles will be useful in other regions where Prosopis species are invasive, and more generally for other widespread invasive tree taxa.

an approach to the development of a National Strategy for controlling invasive alien plant species the case of parthenium hysterophorus in south africa
Bothalia, 2016Co-Authors: Colette Terblanche, Ingrid Nanni, Haylee Kaplan, L W Strathie, A J Mcconnachie, Jeremy Goodall, Brian W Van WilgenAbstract:Invasive alien species require co-ordinated strategic management if negative impacts are to be effectively avoided. Here we describe a Strategy for the management of Parthenium hysterophorus L. (Asteraceae) in South Africa. P. hysterophorus is an annual herb native to tropical America, which has become invasive in over 30 countries. The Strategy sets goals for (1) the prevention of spread to new areas; (2) local eradication of isolated populations; (3) containment in areas where eradication is not possible; and (4) actions to protect assets where containment is no longer an option. We developed both a National Strategy to set policy and to monitor progress towards goals at a National level and an implementation plan to set goals and timeframes for their achievement at local levels. It is not clear, at this stage, whether or not the goals of the Strategy are achievable because implementation will face many challenges arising from ecological features of the target plant, social and cultural practices that will influence management, inadequate levels of funding and multiple political considerations. Our Strategy proposes regular assessment using high-level indicators, a practice that is widely recognised as essential but seldom implemented at a National scale. Because the outcomes are uncertain, it is vital that regular monitoring of outcomes should be instituted from the start, so that both appropriate adjustments can be made to the Strategy and lessons for the implementation of similar strategies elsewhere can be derived.
