Highway work zones interrupt regular traffic flows and create safety problems. Improving safety without sacrificing the main function of highways is a challenging task that traffic engineers and researchers have to confront. In this study, the concept of using crash severity index (CSI) for work zone safety evaluation was proposed and a set of CSI models were developed through the modeling of w...

The paper proposes a new class of income-related health stratification indices that measure the extent to which differences in population health status between the regions of a country are systematically related to regional prosperity. The indices depend in general both on the degree to which the populations of different regions occupy well-defined layers or strata in the national distribution ...

Background: Citations of scientific papers in health care have become a subject of interest, as in any scientific sector. However, such a metric, while useful in a simple way, can become subject to too much credibility, and therefore to advanced analyses which are not soundly grounded even if methodologically valid. Objectives: The objective was to contextualise citation indices in health care ...

Quality control is mandatory, not only for inpatients but also for ambulatory surgery. We propose a list of indices which respond to the key properties of health care that have been defined by Donabedian. These indices should be part of a computerized quality control program which allows comparative evaluation between different centers. © 1998 Elsevier Science B.V. All rights reserved.

The impact of physico-chemical factors on percent coral cover and coral health was examined on a spatial basis for two dominant Acropora species, A. digitifera and A. spicifera, at Ningaloo Reef (north-western Australia) in the southeast Indian Ocean. Coral health was investigated by measuring metabolic indices (RNA/DNA ratio and protein concentration), energy levels (lipid ratio) and autotroph...

Because of the strong relationship between health status and diet quality, many indices have been developed to measure diet quality. Although most of these indices are intended to show a relationship with health outcomes, in all indices this association has been proved to be moderate, especially in the case of obesity. Moreover, all suggested indices are based on a high level of subjectivity in...

background: contamination of swimming pools’ water can lead to the transfer of different diseases to humans. the aim of this study was to investigate the quality of water in kerman swimming pools. methods: in this cross-sectional study, sampling from swimming pools was performed before and after swimming, every week. total number of samples collected was 150 samples. samples were investigated i...

BACKGROUND The study goal was to assess indices of continuity of care in the primary care setting and their association with health outcomes and healthcare services utilization, given the reported importance of continuity regarding quality of care and healthcare utilization. METHODS The study included a random sample of enrollees from Clalit Health Services 19 years-of-age or older who visite...

INTRODUCTION Social exclusion is considered a major factor in the causation and maintenance of health inequalities, but its measurement in health research is still in its infancy. In the Netherlands the Institute for Social Research (SCP) developed an instrument to measure the multidimensional concept of social exclusion in social and economic policy research. Here, we present a method to const...

Various biometeorological indices and temperature measures have been used to assess heat-related health risks. Composite indices are expected to assess human comfort more accurately than do temperature measures alone. The performances of several common biometeorological indices and temperature measures in evaluating the heat-related mortality in Brisbane, Australia—a city with a subtropical cli...
