an upward trend in the divorce rate in iran in recent years has attracted officials, researchers and sociologists towards investigating causes and factors contributing such a social menace. based on the statistics published by the statistics center of iran (sci), the divorce rate has gone up from 1.5 in 1000 cases in 1996 to 2.3 in 1999 and 3.1 in 2006. results of previous studies show that fac...

Background: More than 20% of deaths from traffic crashes are related to pedestrians. This figure in Tehran, the capital of Iran, reaches to 40%. This study aimed to determine the high-risk areas and spatially analyze the traffic crashes, causing death to pedestrians in Tehran. Methods: Mapping was used to display the distribution of the crashes. Determining the distribution pattern of crashes a...

In the last few decades extreme heat events have led to substantial excess mortality, most dramatically in Central Europe in 2003, in Russia in 2010, and even in typically cool locations such as Vancouver, Canada, in 2009. Heat-related morbidity and mortality is expected to increase over the coming centuries as the result of climate-driven global increases in the severity and frequency of extre...

There are many local fragmentation metrics, but most can be grouped into four types (composition/area, isolation, edge, and shape), none of them alone determines the degree a patch. Here, we together main metrics (area, shape, isolation) in order to propose new metric/index, Patch Fragmentation Index (PFI), with which determine at patch scale. The index was subsequently verified Ecuadorian seas...

What are the ecological effects of fires? The evaluation of fireaffected areas and fire severity is of primary importance to answer this question, because fire strongly affects the ecological processes, such as, productivity level, creation of altered patches, modification in vegetation structure and shifts in vegetation cover composition, as well as land surface processes (such as surface ener...

The numerical analysis of spatial point distributions has interested academics for many years. A very early work that resulted in the famous Moran’s I statistic was that by Moran (1948). An early important collection of work on general spatial analysis is that edited by Berry and Marble (1968). The development of spatial point analysis theory is illustrated by such later books by Cliff and Ord ...

This paper aims to explore the spatiotemporal pattern of traffic accidents using five years data between 2015 and 2019 for Irbid Governorate, Jordan. The spatial traffic-accident hotspots their temporal evolution were identified along internal arterial roads network in study area autocorrelation (Global Moran I index) local hotspot analysis (Getis–Ord Gi*) techniques within GIS environment. sho...

Coastal erosion is a common phenomenon along the world’s coasts. Studying it complex because such studies must cover large portions of land, and necessary to understand multiple processes that interact in each area, so important recognize regional patterns allow for defining representativeness relation surrounding dynamics. Spatial statistics can be used coastal geomorphology identify quantify ...
