The speed of social and technological changes is constantly increasing. Change is a prerequisite for economic development but this increasing speed carries additional costs that may largely affect the ability of the social systems to adopt them. While the financial costs constitute a limit to adoption, the psychological and social costs may also profoundly change the adoption potential. In an a...

Regional clusters are spatial agglomerations of firms operating in the same or connected industries, which enable innovation and economic performance for firms. A wealth of empirical literature shows that one of key elements of the success of regional clusters is that they facilitate the formation of local inter-organizational networks, which act as conduits of knowledge and innovation. While m...

Novel derivatives of chromenone bearing an N -carbamothioyl moiety were synthesized and evaluated for their soybean 15-LOX inhibitory activity. Synthesis of the target compounds was started from 7-hydroxy-2H -chromen-2-one. It was reacted with 1-fluoro-2(4)-nitrobenzene to obtain the corresponding nitrophenoxy-chromenone derivative. Reduction of the nitro group was achieved in the presence of Z...

A challenge for search systems is to detect not only when an item is relevant to the user’s information need, but also when it contains something new which the user has not seen before. In the TREC novelty track, the task was to highlight sentences containing relevant and new information in a short, topical document stream. This is analogous to highlighting key parts of a document for another p...

Departing from prior work that demonstrates the stickiness and stability of alliance networks resulting from embeddedness, we extend matching theory to study firms’ withdrawal from alliances. Viewing alliance withdrawal as a result of firms’ pursuit of more promising alternative partners – outside options – rather than failures in collaboration, we predict that a firm is more likely to withdraw...

The nitrocellulose based materials are degraded in a natural way during their storage; the processes of degradation are accelerated when the temperature or the humidity increases. To prevent this decomposition, these materials include in their composition stabilising agents which retain the nitro groups and avoid the autocatalytic degradation of nitrocellulose. The aim of the present work is to...

This paper discusses the performance of a simple GA for parameterizing a particular biomodel consisting of a set of coupled non-linear ordinary differential equations. Comments are offered on the need for speed that motivates choice of language and processing platform for solving scaled problems.

The in-bred laboratory mouse (hereafter referred to as simply mouse) has in the past decades emerged as the go-to animal model in the arena of cardiovascular research. The reasons are straightforward: the relative ease of genetic manipulation coupled with short gestation times, the much cheaper cost of maintaining large numbers, and a large number of similarities to human genomics, proteomics, ...

This article presents a theoretical examination of the digital divide, tracing its origins in the centre–Left social inclusion policy agenda of the 1980s and 1990s to its current status of political ‘hot topic’. It then moves on to outline four conceptual limitations to conventional dichotomous notions of the digital divide and individuals’ ‘access’ to information and communications technology ...
