BACKGROUND We aimed to examine the co-authorship networks in three successful Iranian academic research centers, in order to find the association between the scientific productivity and impact indicators with network features in a case study. METHODS We searched for English articles of the three research centers. We drew co-authorship maps of each center and calculated social network measures...

Rift Valley fever (RVF), a mosquito-borne disease affecting ruminants and humans, is one of the most important viral zoonoses in Africa. The objective of the present study was to develop a geographic knowledge-based method to map the areas suitable for RVF amplification and RVF spread in four East African countries, namely, Kenya, Tanzania, Uganda and Ethiopia, and to assess the predictive accu...

A great deal of work has been done to understand how science contributes to technological innovation and medicine. This is no surprise given the amount of money invested annually in R&D. However, what is not well known is that U.S. science (R&D) investment is only one-sixth that of the annual revenue received by non-profit organizations (NPOs) in the U.S. The large majority of NPO revenues are ...

Layered information systems like Google Earth have revolutionized public access to and visualization of geographic information through virtual globes. Separately, geo-specific technical information has been advanced in mobile platforms, both handheld and embedded devices, for the engineering and scientific communities. However, engineering and scientific information has had limited penetration ...

Geographic studies and spatial analyses have been recognized in Brazilian public health papers. It is still, however, very little explored by researchers. In a survey of the leading scientific journals covering issues related to Brazilian worker's health, we found the predominant use of charts and tables as a way to organize and present results with a small number of maps. This survey was condu...

It is argued that there is no simple metadata solution to the problems of integrating information from multiple scientific disciplines in biodiversity and thus to problems of adopting GIS for producing maps of biodiversity. To the contrary, it is maintained that within this field, GIS needs to take account of and represent an irreducible ontological diversity in the many biodiversity databases ...
