Introduction Since its origin in the late 1980’s, the development of geographical information science and of geographical information systems (GIS), the toolset enabling to conduct this type of research, has now reached the necessary maturity to be considered a main stream application: GIS evolved from the status of ‘a promising tool’ to the status of ‘a tool achieving its promises’. To maintai...

The paper deals with the question of geographical imaginations of so-called Gallus Anonymus, as prevalent in his chronicle. The author sought to reconstruct the chronicler’s mental map of Europe, especially of Sclavonia (Slavonic countries), or, precisely, the concept of space (Raumkonzept) of his work, and the possible sources of his imaginations and knowledge. The author takes under considera...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a rm can costlessly receive external knowledge best. Since knowledge spillovers are unmeasurable, a `goodness of t' measure is constructed using innovation survey data. It turns out that measures of the uncentered correla...

This article addresses the perceptual identification of French regional accents by listeners from the Paris region and Belgium. It is based on the geographical localisation of about thirty speakers from seven French-speaking areas: Vendee (West of France), Languedoc (South of France), Alsace (East of France), Romand Switzerland, East, Centre and West of Belgium. Contrary to the speake bracket (...

We describe here the sequence of the Plasmodium vivax mdr1 gene from 10 different isolates differing in chloroquine sensitivity. The deduced amino acid sequence of PvMDR1 shares more than 70% similarity with other malarial MDR proteins and it displays consensus motifs of an ABC family transporter including two transmembrane domains and two ATP binding cassettes. Similarity and dendrogram analys...

Most research on family interventions of children with autism has focused on the role of the mother, and little is known about the effects of training fathers. Through a series of National Institutes of Health– funded studies we have demonstrated treatment success by focusing on fathers who are trained at home. Although our research has been successful, this work introduces questions related to...

Since at least the sixteenth century, the areas of the present day regions of Harar and Wallo have been important centres of teaching and diffusion of Islam as well as of preservation of Islamic culture and education. Preachers and scholars from these areas played a decisive role in the introduction and dissemination of the faith in the country, especially in the eighteenth and nineteenth centu...

Orchardgrass, or cocksfoot, is an important perennial forage grass worldwide. The comprehensive understanding of orchardgrass accessions will benefit germplasm collection and breeding progress, and it will enhance efforts to improve forage yield and quality. Therefore, 24 novel, simple, polymorphic, and reliable start codon-targeted (SCoT) markers were used to analyze the diversity and genetic ...

The increasing abundance of human genetic data has shown that the geographical patterns of worldwide genetic diversity are best explained by human expansion out of Africa. This expansion is modelled well by prolonged migration from a single origin in Africa with multiple subsequent serial founding events. We discuss a new simulation model for the serial founder effect out of Africa and compare ...
