Identification and management the 'critical risk areas' where hotspot lead exposures are a potential risk to human health, become a major focus of public health efforts in China. But the knowledge of health risk assessment of lead pollution at regional and national scales is still limited in China. In this paper, under the guidance of 'sources-pathways-receptors' framework, regional human healt...

The evaluation model on technical innovation ability of small and medium enterprises is set up based on analytic hierarchy process and fuzzy comprehensive evaluation methods, which takes quantitative index as main parts and considers reality so that better practicability is obtained. Meanwhile, technical innovation ability of small and medium enterprises in Heilongjiang Province of China are ob...

In this article, we applied the AHP method with quantitative analysis and qualitative analysis to analyze three sorts of basic educational mode combining production with learning and research, i.e. the automated instruction, the mode combining production and learning, and the integration combining production with learning and research, and obtained that the educational mode combining production...

Over the last decade, managed-care companies have been consolidating on both a regional and national scale. More recently, nonprofit health plans have been converting to for-profit status, and this conversion has frequently occurred as a step to facilitate merger or acquisition with a for-profit company. Some industry observers attribute these managed-care marketplace trends to an industry shak...

Large-scale ecosystem management involves consideration of many factors for informed decision making. The EverVIEW Data Viewer is a cross-platform desktop decision support tool to help decision makers compare simulation model outputs from competing plans for restoring Florida's Greater Everglades. The integration of NetCDF metadata conventions into EverVIEW allows end-users from multiple instit...

OBJECTIVE A new measurement of health care quality for Medicare beneficiaries has been implemented by the Health Care Financing Administration (HCFA). This paper describes the program, presents baseline data and highlights associated issues. DESIGN The Health Outcomes Survey (HOS) is a longitudinal cohort mail survey. Changes in population health status after 2 years will be evaluated on an i...

Since the mid-20th century, most large cities of the United States have been warming at more than twice the rate of the planet as a whole. While many municipal and state governments have developed climate action plans designed to reduce emissions of greenhouse gases, rising concentrations of greenhouse gases typically are not the strongest driver of warming in cities. Our purpose is to evaluate...

Many large-scale machine learning (ML) systems allow specifying custom ML algorithms by means of linear algebra programs, and then automatically generate efficient execution plans. In this context, optimization opportunities for fused operators—in terms of fused chains of basic operators—are ubiquitous. These opportunities include (1) fewer materialized intermediates, (2) fewer scans of input d...

As large-scale sensor networks are being deployed with the objective of collecting quality data to support user queries and decision-making, the role of a scalable query model becomes increasingly critical. An effective query model should scale well with large network deployments and address user queries at specified confidence while maximizing sensor resource conservation. In this paper, we pr...

To explain complex phenomena, an explanation system must be able to select information from a formal representation of domain knowledge, organize the selected information into multisentential discourse plans, and realize the discourse plans in text. Although recent years have witnessed significant progress in the development of sophisticated computational mechanisms for explanation, empirical r...
