OBJECTIVE To investigate the association between homicide rates and socio-economic variables taking into account the spatial site of the indicators. METHODS An ecological study was conducted. The dependent variable was the rate of homicides among the male population aged 15 to 49 years, residing in the districts of the State of Pernambuco from 1995 to 1998. The independent variables were an i...

Knowledge about the spectral variability in a field or region of interest becomes important when it comes to defining a representative spectrum of a certain spatial extent, used for example as an endmember in spectral unmixing techniques. An approach is presented using high spatial resolution panchromatic data to assess the spectral variability of a hyperspectral dataset. The spatial variabilit...

Based on time and spatial dynamic considerations, this study evaluates the potential role of short- and long-distance dispersal in the spread of coffee wilt disease (CWD) in a large commercial Robusta coffee estate in Uganda (Kaweri, 1,755 ha) over a 4-year period (2008 to 2012). In monthly surveys, total disease incidence, expansion of infection foci, and the occurrence of isolated infected tr...

due to deep, complex and everlasting interaction between precipitation and climatic elements-factors, there are changes and varieties in both time and space dimensions. so that climate experts and related scientists take their attentions to this phenomenon. an approach to do this kind of investigations is to describe spatial variations based on spatial statistics. in this paper the main object ...

Satellite data have been used for temperature modeling both in urban areas and water. This paperstudies viability of ASTER satellite images that provide high spatial and spectral resolution to model watersurface temperature, as a fundamental water quality parameter. This study is focused on Dez dam reservoirresiding in Khuzestan province, south west of Iran. After the image corrections required...

In this study, we examined the geographical distribution (the spatial structure) of mortality and prosperity in Malaysia. In addition we proposed an approach to investigate the association between clustering patterns of mortality and prosperity across different areas of the country. To characterize the geographic pattern of mortality and prosperity, three indicators (infant, neonatal, and still...
