Academic inbreeding: local challenge, global problem

Navel Gazing: Academic Inbreeding and Scientific Productivity

The practice of having PhDs employed by the university that trained them, commonly called "academic inbreeding" has long been assumed to have a damaging effect on scholarly practices and achievement. Despite this perception, existing work on academic inbreeding is scarce and mostly descriptive or speculative. In this research we show, first, that academic inbreeding can be damaging to scholarly...

Distributed Flow Shop Scheduling Problem - Global versus Local Optimization

Because of its highly combinatorial aspect, its dynamic nature and its practical interest for manufacturing systems, the scheduling problem has been widely studied in the literature by various methods: heuristics, constraint propagation techniques, Constraint Satisfaction Problem formalism, simulated annealing, Taboo search, genetic algorithms, neural networks, etc. This paper deals with the Fl...

Global Graph Properties byMeans of Local Computations : the Majority Problem

This paper is a contribution to the study of the general problem of characterizing those properties which can be computed on a graph or a network by means of local transformations. By using an abstract model based on graph relabelling systems we consider the majority problem : let G be a graph whose vertices have label A or B ; we say that label A has the majority if the number of A-labelled ve...
