In this paper we develop and test an encompassing theoretical framework for the explanation of the geographical and temporal spread of extreme right violence. This framework combines internal precipitating factors related to ethnic competition, social disintegration, and political opportunity structures, which make certain localities more prone to exhibit ethnic violence, with diffusion variabl...

Geographic structure can affect patterns of genetic differentiation and speciation rates. In this article, we investigate the dynamics of genetic distances in a geographically structured metapopulation. We model the metapopulation as a weighted directed graph, with N vertices corresponding to N homogeneous subpopulations. The dynamics of the genetic distances is then controlled by two types of ...

Toponym disambiguation or location names resolution is a critical task in unstructured text, articles or documents. Our research explores how to link ambiguous locations mentioned in documents, news and articles with latitude/longitude coordinates. We designed an evaluation system for toponym disambiguation based on annotated GEOCLEF data. We implemented a node-based approach taking population ...

In this contribution the authors examine robotics research itself. We look at the data which the European funded ECHORD project (European Clearing House for Open Robotics Development) generated. The project began in January 2009 with the ambitious goal of bringing together European robotics manufacturers with the European research institutions and it ended in 2013. We will especially look at th...

Network wide broadcasting is an energy intensive function. In this paper we propose a new method that performs transmission power adaptations based on information available locally, to reduce the overall energy consumed per broadcast. In most of the prior work on energy efficient broadcasting it is assumed that the originator of the broadcast has global network information (both topology inform...

The oldest branch of dialectology is the study of what is today often referred to as " dialect geography " , i.e. the study of the geographical distribution of language varieties, as opposed to the study of many other relations between language varieties and external conditioning factors, such as social class, age, and sex. While it is clear that geography has a massive influence on the distrib...

Research has increasingly focused on intentional or planned lesbian, gay, bisexual (LGB)parent families; however, how young adults in these families navigate the aftermath of parental break-up and subsequent repartnering is unexamined. This qualitative study of 20 young adults who had experienced their LGB parents’ relationship dissolution and/or the formation of an LGB stepfamily examined how ...

While the debate on whether countries should or should not sign trade agreements with selected partners continues, governments have significantly stepped up the rate at which they enter into such agreements. A number of such agreements have been signed lately and many more are under negotiation. Multinational firms get impacted by these agreements irrespective of whether these are beneficial to...

Context: The context of this paper is Global Software Development (GSD) which is a current trend concerning the development of software in a distributed manner throughout different countries. This paradigm has several advantages, but unfortunately there are a number of challenges that hinder projects’ successful development. Objective: The main goal of this paper is to discover which factors af...

Radio labeling is derived from the assignment of radio frequencies (channels) to a set of transmitters. The frequencies assigned depend on the geographical distance between the transmitters: the closer two transmitters are, the greater the potential for interference between their signals. Thus when the distance between two transmitters is small, the difference in the frequencies assigned must b...
