No full textA Random Base Change Algorithm for Permutation Groups
No full textAbstractA new random base change algorithm is presented for a permutation group G acting on n points whose worst case asymptotic running time is better for groups with a small to moderate size base than any known deterministic algorithm. To achieve this time bound, the algorithm requires a random generator Rand(G) producing a random element of G with the uniform distribution and so that the time for each call to Rand (G) is bounded by some function f(n, G). The random base change algorithm has probability 1 - 1/|G| of completing in time O(f(n, G) log |G|) and outputting a data structure for representing the point stabilizer sequence relative to the new ordering. The algorithm requires O(n log |G|) space and the data structure produced can be used to test group membership in time O(n log |G|). Since the output of this algorithm is a data structure allowing generation of random group elements in time O(n log |G|), repeated application of the random base change algorithms for different orderings of the permutation domain of G will always run in time O (n log2 |G|). An earlier version of this work appeared in Cooperman and Finkelstein (1992b)

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
