Rating of researchers, and thus possibly also funding, is often based on the h-index or Hirsch index (Hirsch, 2005) which in turn is a function of the number of publications and citations received based on their publications. Impact numbers of journals are also based on citations. The purpose of this work is to show the differences between the average number of citations for various subject fie...

Table B1 presents results from a specification identical to the one presented in Table 2 of the paper using an alternative measure of the concentration of power. This measure is the number of times the family that has held the paramount chieftaincy most has done so (i.e., the maximum of the number of times any family has held the chieftaincy). The mean of this variable is 3.5. The results are v...

Given an infinite-dimensional Banach space X, we introduce the daugavetian index of X , daug (X), as the greatest constant m > 0 such that kId+ Tk > 1 +mkTk for all T ∈ K(X). We givetwo characterizations of this index and we estimate it in some examples. We show that the daugavetian index of a c0-, l1or l∞-sum of Banach spaces is the infimum index of the summands. Finally, we calculate the daug...

We investigate the minimum and maximum number of colors in edge-colorings of Kn,n such that every copy of Kp,p receives at least q and at most q′ colors. Along the way we improve the bounds on some bipartite Turán numbers.

The concept of revealed comparative advantage as measured by the Balassa index is widely used in practice to determine a country’s weak and strong sectors. Interpreting the Balassa index is difficult however in view of the limited knowledge to date on the distribution of this index. We analyze the empirical distribution of the Balassa index and its stability and properties over time, using Japa...

We characterize edge-colored graphs in which every edge belongs to some properly colored cycle. We obtain our result by applying a characterization of 1-extendable graphs.
