Many studies have reported associations between air pollution and daily asthma occurrence. Those studies have not consistently specified the lag between exposure and response, especially multiple lags, although most have found associations that persisted for more than 1 day. A systematic approach to specifying the lag association would allow better comparison and give insight into the nature of...
This study examines the causal relationship between international public relations expenditure and its economic returns at the country level. In order to overcome the limitations of previous studies that have attempted to quantify the outcomes of public relations efforts and investments using correlations, this study conducted a more rigorous causality test by measuring the relationship between...
Purpose: This study is the first to examine the effect of extreme weather on mortality in Cyprus. It aims to investigate the individual effect of meteorological indicators on mortality, as well as the role of air pollution as a potential confounder of heat related health effects. Methods: The analysis concentrated on the warm periods (April to September) of the years 2007-2009. A Generalized Li...
background: injuries and deaths from road traffic crashes are one of the main public health problems throughout the world. this study aimed to identify determinants of fatality traffic accident in iran for the twenty-span year from 1991 to 2011. methods: a time series analysis (1991-2011) was used to examine the effects of some of the key explanatory factors (gdp per capita, number of doctors p...
globalization is integration of national economies in global economy and infers on increasing the flow of goods and services. in this study the consequences of globalization were studied through the analysis of level of international trade index (lit) in the caviar export equation. the required data were gathered from statistical yearbook of foreign trade, statistical yearbook of fisheries, sta...
background: a dramatic increase in healthcare expenditures is a major health policy concern worldwide. understanding factors that underlie the growth in healthcare expenditures is essential to assist decision-makers in finding best policies to manage healthcare costs. we aimed to examine the determinants of healthcare spending in iran over the periods of 1978-2011. methods: a time series analys...
As climate continues to change, scientists are left to analyze the effects these changes will have on the public. In this article, a flexible class of distributed lag models are used to analyze the effects of heat on mortality in four major metropolitan areas in the U.S. (Chicago, Dallas, Los Angeles, and New York). Specifically, the proposed methodology uses Gaussian processes as a prior model...
