In hybrid zones genetically differentiated populations meet and interbreed. As they result from ongoing divergence and potential speciation, such zones provide opportunities to study how different factors affect this process. The hybrid zone between the all black carrion crow (Corvus corone corone) and the grey and black hooded crow (Corvus c. cornix) stretches c. 2400 km throughout Europe. I have

Research on retail internationalization and internationalization in general acknowledges the relevance of knowledge management and organizational learning, even though there is a lack of discussion about the specific constructs and approaches that would be most fruitful. The central role of knowledge sharing in the internationalization process is rarely stressed. Furthermore, the specificities of
This chapter describes and analyzes the public relations strategies and practices of a public organization, a local rescue services, in the process of establishing credibility and building trust in multicultural areas. The trust-building efforts are a response to several years of social unrest, communicative clashes and hostile treatment between operative firemen and residents in certain areas. Th
The focus of attention in this article is that of milieux as forges for creativity and renewal. Among the milieux presented are places, corporations and research institutions. The renewal discussed here includes art, architecture, music and literature as well as science and technology. The goal of this article is to identify characteristics of importance in environments where exceptionally creativ
The spectral efficiency of a volume in a MIMO environment is analyzed. The analysis is based on a spherical mode expansion for the propagation, the radiation Q for the antennas, and Fano theory for the broadband matching
This paper investigates the mean square error optimal time-frequency kernel for estimation of the Wigner-Ville spectrum of a certain class of nonstationary processes. The class of locally stationary processes have a simplified covariance structure which facilitates analysis. We give a formula for the optimal kernel in the ambiguity domain and conditions that are sufficient for the optimal time-fre
