Automated Cartographic Sounding Selection

Soundings on nautical charts provide information about the shape of the ocean bottom between chart depth curves. A single chart may have thousands of soundings posted on it. Today, the selection of soundings for chart display is usually performed manually. This paper describes a computer system which automatically selects soundings for display on a nautical chart. The system is composed of several computer programs which make use of a grid-based model of the ocean bottom. The ocean bottom model is initialized by gridding the depth curves and shoreline displayed on the nautical chart. Soundings which deviate from the ocean bottom model are selected for chart display. Based on initial results obtained from testing these programs, it appears that a significant part of the work required to select soundings for chart display can be automated

Barriers to evidence-based disaster management in Nepal: a qualitative study

Objectives: Globally, the incidence of natural disasters is increasing with developing countries tending to be worst affected. Implementing best practices in disaster management that are evidence-based is essential in order to improve disaster resilience and response. This study explores the barriers to evidence-based disaster management encountered in Nepal. Study design: A qualitative study was conducted in Nepal involving interviews with key informants in the disaster management field. Methods: Government officials, academics, programme managers, disaster management practitioners and policymakers involved in disaster management were purposively sampled and invited to interview. 11 agreed to participate and were interviewed. The faceto-face interviews were recorded, transcribed and analysed using thematic analysis. Results: The interviews uncovered population-level barriers such as contextual factors (e.g. poverty), local custom and culture, as well as community-level issues (e.g. level of engagement and understanding). System-level barriers included limited demand for, availability and accessibility of the evidence-base. The implementation of evidence was influenced by the configuration of the disaster management system and system processes. Political ownership and leadership is an essential determinant of practice. Conclusions: Several barriers to evidence-based practice in disaster management exist in Nepal. The relative influence of the different barriers varies with political determinants likely to have greater importance in countries such as Nepal where system governance and leadership is insufficiently developed. These issues affect a country's vulnerability to disasters and need to be addressed

Learning lessons from the 2011 Van Earthquake to enhance healthcare surge capacity in Turkey

Historically, Turkey has adopted a reactive approach to natural hazards which resulted in significant losses. However, following the 1999 Kocaeli Earthquake, a more proactive approach has been adopted. This study aims to explore the way this new approach operates on the ground. A multi-national and multi-disciplinary team conducted a field investigation following the 2011 Van Earthquake to identify lessons to inform healthcare emergency planning in Turkey and elsewhere. The team interviewed selected stakeholders including, healthcare emergency responders, search and rescue services, ambulance services, and health authority representatives, in addition to conducting a focus group. Data were analysed according to an open coding process and SWOT analysis. The findings suggest that the approach succeeded in developing a single vision by consolidating official efforts in a more structured way, mobilising many governmental and non-governmental organisations, securing significant amounts of resources including physical and human, and increasing the resilience and flexibility of infrastructure to expand its capacity. However, more attention is required to the development of stronger management procedures and acquisition of further resources

Optimizing emergency preparedness and resource utilization in mass-casualty incidents

This paper presents a response model for the aftermath of a Mass-Casualty Incident (MCI) that can be used to provide operational guidance for regional emergency planning as well as to evaluate strategic preparedness plans. A mixed integer programming (MIP) formulation is proposed for the combined ambulance dispatching, patient-to-hospital assignment, and treatment ordering problem. T he goal is to allocate effectively the limited resources during the response so as to improve patient outcomes, while the objectives are to minimize the overall response time and the total flow time required to treat all patients, in a hierarchical fashion. The model is solved via exact and MIP-based heuristic solution methods. The applicability of the model and the performance of the new methods are challenged on realistic MCI scenarios. We consider the hypothetical case of a terror attack at the New York Stock Exchange in Lower Manhattan with up to 150 trauma patients. We quantify the impact of capacity-based bottlenecks for both ambulances and available hospital beds. We also explore the trade-off between accessing remote hospitals for demand smoothing versus reduced ambulance transportation times

Effectiveness of Mechanisms and Models of Coordination between Organizations, Agencies and Bodies Providing or Financing Health Services in Humanitarian Crises: A Systematic Review.

BACKGROUND: Effective coordination between organizations, agencies and bodies providing or financing health services in humanitarian crises is required to ensure efficiency of services, avoid duplication, and improve equity. The objective of this review was to assess how, during and after humanitarian crises, different mechanisms and models of coordination between organizations, agencies and bodies providing or financing health services compare in terms of access to health services and health outcomes. METHODS: We registered a protocol for this review in PROSPERO International prospective register of systematic reviews under number PROSPERO2014:CRD42014009267. Eligible studies included randomized and nonrandomized designs, process evaluations and qualitative methods. We electronically searched Medline, PubMed, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, PsycINFO, and the WHO Global Health Library and websites of relevant organizations. We followed standard systematic review methodology for the selection, data abstraction, and risk of bias assessment. We assessed the quality of evidence using the GRADE approach. RESULTS: Of 14,309 identified citations from databases and organizations' websites, we identified four eligible studies. Two studies used mixed-methods, one used quantitative methods, and one used qualitative methods. The available evidence suggests that information coordination between bodies providing health services in humanitarian crises settings may be effective in improving health systems inputs. There is additional evidence suggesting that management/directive coordination such as the cluster model may improve health system inputs in addition to access to health services. None of the included studies assessed coordination through common representation and framework coordination. The evidence was judged to be of very low quality. CONCLUSION: This systematic review provides evidence of possible effectiveness of information coordination and management/directive coordination between organizations, agencies and bodies providing or financing health services in humanitarian crises. Our findings can inform the research agenda and highlight the need for improving conduct and reporting of research in this field

New York City Panel on Climate Change 2015 ReportChapter 5: Public Health Impacts and Resiliency

Recent experience from Hurricane Sandy and high temperature episodes has clearly demonstrated that the health of New Yorkers can be compromised by extreme coastal storms and heat events. Health impacts that can result from exposure to extreme weather events include direct loss of life, increases in respiratory and cardiovascular diseases, and compromised mental health. Other related health stressors—such as air pollution, pollen, and vector-borne, water-borne, and food-borne diseases— can also be influenced by weather and climate. Although New York City is one of the best prepared and most climate-resilient cities in the world, there remain significant potential vulnerabilities related to climate variability and change. As part of the NPCC2 process, a team of local climate and health specialists was mobilized to assess current vulnerabilities and to identify strategies that could enhance the resilience of New York City to adverse health impacts from climate events. The goal was to highlight some of the important climate-related health challenges that New York City is currently facing or may face in the future due to climate variability and change, based on emerging scientific understanding

Imposing Geologic Interpretations on Computer-Generated Contours Using Distance Transformation

Developing practical computer programs to impose geologic interpretations an computer-generated contours has proven to be difficult. Today, complex data transformation, tedious contour editing, or both are used to achieve that goal. This paper introduces a new program for incorporating high-quality geologic interpretations into computer contouring. The program is robust, easy to implement, and easy to explain to potential users. The computational complexity of the program is high, but the results are worth the price. KEY WORDS: surface modeling, gridding, directional bias, anisotropy
