Visualizing Library and Information Science concept spaces through keyword and citation based maps and clusters

Co-citation analysis has been widely accepted as the foremost method for bibliometric mapping of research fields, whereas analyses based on keywords has been discussed, without gaining any overall acceptance. There is, however advantages with keywords, such as being understandable by others than those immediately connected to the field analyzed. This study aims at testing the relation between keyw

Understanding the First Hundred Years of Christian Identity

After stating that there did exist an early Christ-believing movement in the first century CE, distinct enough to be investigated, the chapter gives a review of recent scholarly approaches to what "Christian identity" is. Answers range from a textual reality only, to an ideological construct, or rhetorical construction with social effectiveness, or an autonomous inner structure of the semiotic sys

Ethanol production by recombinant and natural xylose-utilising yeasts

The xylose-fermenting capacity of recombinant Saccharomyces cerevisiae carrying XYL1 and XYL2 from Pichia stipitis, which encode xylose reductase (XR) and xylitol dehydrogenase (XDH), respectively, is poor due to high xylitol formation. Whereas, P. stipitis exhibits high ethanol yield on xylose, the tolerance towards inhibitors in the lignocellulosic hydrolysate is low. A recombinant strain posses

A fast approximation algorithm for TSP with neighborhoods and red-blue separation

In TSP with neighborhoods (TSPN) we are given a collec-tion X of k polygonal regions, called neighborhoods, with totally n ver-tices, and we seek the shortest tour that visits each neighborhood. TheEuclidean TSP is a special case of the TSPN problem, so TSPN is alsoNP-hard. In this paper we present a simple and fast algorithm that, givena start point, computes a TSPN tour of length O(log k) times

Paradoxical Relationships in Collaboration, Competition and Innovation: a Critical Systemic Perspective

This paper seeks to discuss the nature of complex relationships among participants in organizational life, including ways in which paradox and ambiguity in their interactions impact upon organizational performance. Any relationship emerges and subsists through interaction between people. The nature of a relationship is the result of double description (Bateson, 2002). Each of the parties involved
