Minimum spanning tree is a classical polynomial problem very well known in operational research and in theoretical computer science. In this paper, we settle the reoptimization versions of this problem, which can be formulated as follows: given an instance of the problem for which we already know some optimal solution, and given some “small” perturbations on this initial instance, is it possibl...

Instructional technology, and the cognitivist and systems paradigms that underpin it, grew out of the military-industrial complex during the Cold War. Much as the Pentagon and this military complex defined the architecture of the Internet, they also essentially created, ex nihilo, the fields of instructional technology and instructional design. The results of the ongoing dominance or influence ...

We can learn about people’s conceptions of the ideal life by looking at what they imagine heaven to be like. Although voluptuous and gendered (and even sexist) accounts of the afterlife are familiar, more reflective views grow ever more distant from our actual human form of life—many Christians believe that in heaven there will be no marriage, sexual intercourse, or procreation. For those of us...

Traditional radio systems are strictly co-designed on the lower levels of the OSI stack for compatibility and efficiency. Although this has enabled the success of radio communications, it has also introduced lengthy standardization processes and imposed static allocation of the radio spectrum. Various initiatives have been undertaken by the research community to tackle the problem of artificial...

Active OODBMSs must provide eecient support for event detection, composition, and rule execution. Previous experience, reported here, building active capabilities on top of existing closed OODBMSs has proven to be ineeective. We propose instead an active OODBMS architecture where event detection and rule support are tightly integrated with the rest of the core OODBMS functionality. After presen...

The sociology of knowledge can provide another tool for the scholar's workbench as he or she attempts to disclose the deeper meanings of an ancient document. Writers such as Peter Berger, Clifford Geertz, Thomas Luckmann, Karl Mannheim, and Alfred Schutz (note particularly the works cited in the bibliography} have outlined the ways in which people gather and transmit knowledge (or traditions), ...

Intelligent design (ID)-the latest incarnation of religious creationism-posits that complex biological features did not accrue gradually via natural evolutionary forces but, instead, were crafted ex nihilo by a cognitive agent. Yet, many complex biological traits are gratuitously complicated, function poorly, and debilitate their bearers. Furthermore, such dysfunctional traits abound not only i...

Distances on symbolic musical sequences are needed for a variety of applications, from music retrieval to automatic music generation. These musical sequences belong to a given corpus (or style) and it is obvious that a good distance on musical sequences should take this information into account; being able to define a distance ex nihilo which could be applicable to all music styles seems implau...
