    Refined Simulations of the Reaction Front for Diffusion-Limited Two-Species Annihilation in One Dimension

    Extensive simulations are performed of the diffusion-limited reaction A++B→0\to 0 in one dimension, with initially separated reagents. The reaction rate profile, and the probability distributions of the separation and midpoint of the nearest-neighbour pair of A and B particles, are all shown to exhibit dynamic scaling, independently of the presence of fluctuations in the initial state and of an exclusion principle in the model. The data is consistent with all lengthscales behaving as t1/4t^{1/4} as t→∞t\to\infty. Evidence of multiscaling, found by other authors, is discussed in the light of these findings.Comment: Resubmitted as TeX rather than Postscript file.

    Sharing the Prosperity: Why We Still Need Organized Labor

    Today economic inequality is greater in the United States than in any other advanced nation. Bringing the minimum wage up to a true living wage is a crucial step forward, as are other employment-related benefits like broadening access to overtime and instituting paid sick leave. But employment statutes such as minimum-wage regulations cannot replace the broad-based benefits that come from organized labor. Unionization places the ability to influence what happens in the workplace directly in workers’ own hands, even as it creates institutions that can advocate for working people at the community, state, and national level. Under an effective labor-law regime, unions remain the unique vehicle for worker empowerment. As envisioned by Senator Robert Wagner more than eighty years ago, a strong union movement is the most effective tool for strengthening economic and political democracy
