In the eld of geography, we have beenexamining the contribution of the morpho-genetic rep-resentation to the comprehension of the cycle: reality,representation, model, reality. A distinction is madebetween map and geomap based on the notion of locus-object. 1. Foundations and limits of cartographic rep-

This paper studies the impact of the R&D offshoring of multinational enterprises on the firms in host emerging economies. We develop a two-stage non-cooperative game to analyze the strategic interaction between multinational and host country enterprises engaged in R&D investment. An empirical analysis of 12,309 manufacturing firms in the ICT industry in China shows that R&D offshoring has a pos...

In prehistoric studies of Iran, the Abharrood River Basin, located on the east of Zanjan province and in the northwestborder of the Central Plateau, is one of the little-known and dark regions. Studying this region according to itsenvironmental features and geographical location is important for understanding regional relations and interregionalinteractions between three cultural-geographical a...

Valuable resources often exist at distant points from a firm’s current locations, so that strategic decisions such as growth have a spatial dimension in which firms seek information and choose between geographically distributed alternatives. Studies show that geographic proximity facilitates the flow of resources, but there is limited understanding of factors that exacerbate or ease the impact ...

The cultivated apple (Malus domestica) is one of the most important fruit crops cultivated in different regions of the world including Iran. For production and breeding of high quality apple, the knowledge of genetic diversity of the cultivated apples  is  necessary. Therefore we studied genetic diversity of 25 genotypes by using ISSR molecular markers. In present study, ten ISSR primers produc...

Remote sensing images contain huge amount of geographical information and reflect the complexity of geographical features and spatial structures. Fractal geometry provides a means of describing and analyzing the complexity of different geographical features in remotely sensed images. It also provides a more powerful tool to compress the remote sensing data than traditional methods. In this stud...

Automatically detecting geographical objects such as bridges, roundabouts or road crossings on highresolution satellite images is useful for keeping up to date geographical databases, automatically locating the imaging satellite at low cost, and easily and quickly assessing the extent of damages in case of natural disasters such as flooding or earthquakes. In addition, it may help in content-ba...
