Geography versus topology in the European Ownership Network
2011
In this paper, we investigate the network of ownership relationships among European firms and its embedding in the geographical space. We carry out a detailed analysis of geographical distances between pairs of nodes, connected by edges or by shortest paths of varying length. In particular, we study the relation between geographical distance and network distance in comparison with a random spatial network model. While the distribution of geographical distance can be fairly well reproduced, important deviations appear in the network distance and in the size of the largest strongly connected component. Our results show that geographical factors allow us to capture several features of the netw…
Distance Factors in the Foreign Market Entry of Software SMEs
2010
Recent studies have indicated that the internationalization process of software SMEs is somewhat independent on the effect of psychic or geographic distance. However, these studies have analyzed the general pattern of entries where software SMEs not commonly follow a step-wise entry route from nearby countries to distant ones. Thus, it remains unknown what the effect of psychic and geographical distance is when these firms enter a distant foreign market. The findings in this case study reveal that psychic and geographic distance inhibited the foreign market entry of software SMEs. However, the distant foreign market entry of these firms was facilitated by distance-bridging and distance-comp…
Energy and speleogenesis: Key determinants of terrestrial species richness in caves
2017
Abstract The aim of this study was to unravel the relative role played by speleogenesis (i.e., the process in which a cave is formed), landscape‐scale variables, and geophysical factors in the determination of species richness in caves. Biological inventories from 21 caves located in the southeastern Iberian Peninsula along with partial least square (PLS) regression analysis were used to assess the relative importance of the different explanatory variables. The caves were grouped according to the similarity in their species composition; the effect that spatial distance could have on similarity was also studied using correlation between matrices. The energy and speleogenesis of caves account…
