The objective of this paper is to develop a conceptual model for client-vendor distance in global IS outsourcing relationships as previous research on this issue is scarce. A multi-dimensional construct is deductively developed deploying the theory of psychic distance as a theoretical lens. A key finding is that client-vendor distance in global IS outsourcing relationships is constituted by sev...

This vignette describes gdistance, an R package which provides functionality to calculate various distance measures and routes in heterogeneous geographic spaces represented as grids. Distances are fundamental to geospatial analysis (Tobler 1970). The most commonly used geographic distance measure is the great-circle distance, which represents the shortest line between two points, taking into a...

Offshore software development projects provoke new issues to the collaborative endeavor of software development due to their global distribution and involvement of various people, processes, and tools. These problems relate to the geographical distance and the associated time-zone differences; cultural, organizational, and process issues; as well as language problems. However, existing tool sup...

Metadata are data about data. Geographical metadata describe geospatial data: maps, satellite images or other geographically referenced material. The two characteristics of geographical metadata, high dimensionality and diversity of attribute data types, present a problem for automatic data mining. We present an approach for exploration of geographical metadata which is based on an integration ...

Around the world, China fever has replaced China fear. Multi-national enterprises (MNEs) are doing more than just talking about foreign direct investment (FDI) in China. Differences in local thing in their broadest senses, including policy barriers at the borders, nature and geography, and economic differences, contribute to its distinctiveness. Thus, this study reviews, discusses and re-concep...

a place-name or a toponym is a word used to indicate, denote or identify a geographic locality. place-names are formed in the course of history of a region and are affected by various linguistic, social, political and cultural events. toponymy is the taxonomic study of place-names, based on etymological, historical and geographical information. this paper first defines toponym and topnymy and i...

We introduce geoplotlib, an open-source python toolbox for visualizing geographical data. geoplotlib supports the development of hardware-accelerated interactive visualizations in pure python, and provides implementations of dot maps, kernel density estimation, spatial graphs, Voronoi tesselation, shapefiles and many more common spatial visualizations. We describe geoplotlib design, functionali...

Data from freight traffic roadside surveys in Mexican highways are analyzed in order to find consistent patterns or systematic relationships between variables characterizing this traffic. Patterns traced are validated by contrasting against new data sets, allowing so a pattern’s description refinement. In a first stage truck traffic is characterized with respect to vehicle counting size, month ...

In wireless sensor networking applications, gathering sensed information and relaying it to the sink node using multi-hop communication in an energy efficient manner is of paramount importance. In this paper we present the idea of using Aggregator Nodes in order to decrease the amount of packets sent, hence reducing the energy required for communication. We introduce DDAP, a self-organizing Dis...

Nowadays, there are many attempts to establish object-oriented GIS in some software However, they are not accordant to object-oriented concept whole and systematically in the whole course from the process of cognizing and abstracting geographical space to the process of defining and describing GIS data model then to the process of analyzing and designing GIS. Especially, the research on common ...
