TL;DR: This paper examined the relationship between political regime changes and the position of nations in the world economy over the last two decades, to argue that democratic transitions have been centered among semiperipheral nations.
Abstract: The dramatic global transition to democracy of the last decade reveals important systematic patterns. Using recent contributions to world-systems theory, this study examines the relationship between political regime changes and the position of nations in the world-economy over the last two decades, to argue that democratic transitions have been centered among semiperipheral nations. The study also found a strong relationship between the structure of the labor force and the global distribution of democratic institutions, but a weak relationship between the structure of the labor force and the timing of transitions in the semiperiphery. Overall, the findings suggest that world-systemic categories provide a useful vantage point to distinguish global trends from the specific characteristics of individual nations, thereby allowing for greater analytical precision in identifying the crucial causal relations shaping transitions from dictatorship to democracy.

TL;DR: In this article, a simple measurement procedure for screening polycyclic aromatic hydrocarbons and their metabolites in urine using room temperature phosphorescence (RTP) was developed, where the signal intensities were proportional to the amounts of benzo(a)pyrene-r-7,t-8,9,10,tetrahydrotetrol (BPT) below 75 pmol per spot.

Abstract: If X 1, X 2, X 3, … are iid random vectors and A n(X 1 + … + X n) - b n converges weakly to a nondegenerate limit Y, then Y is operator-stable In other words there is a matrix B called an exponent of Y such that for all n = 1,2,3, … if Y1, Y2, Y3, … are iid with Y then exp(-B log n)(Y 1 + … + Y n) is identically distributed with Y + a n for some a n Computation of the norming matrices A n is complicated by the fact that Y may possess a complex symmetry structure The set of symmetries of Y forms a compact group G with the property that exp(Bs)G exp(-Bs) = G for all real s We use this fact to compute G The computer algebra system Maple is used to perform the necessary matrix calculations
