Effective Governance of Global Financial Markets:An Evolutionary Plan for Reform

Runaway electrons, which are generated in a plasma where the induced electric field exceeds a certain critical value, can reach very high energies in the MeV range. For such energetic electrons, radiative losses will contribute significantly to the momentum space dynamics. Under certain conditions, due to radiative momentum losses, a non-monotonic feature - a ‘bump' - can form in the runaway electron tail, creating a potential for bump-on-tail-type instabilities to arise. Here, we study the conditions for the existence of the bump. We derive an analytical threshold condition for bump appearance and give an approximate expression for the minimum energy at which the bump can appear. Numerical calculations are performed to support the analytical derivation

Evaluating Pooled Evidence from the Reemployment Bonus Experiments

Social experiments conducted in Pennsylvania and Washington tested the effect of offering Unemployment Insurance (UI) claimants a cash bonus for rapid reemployment. This paper combines data from the two experiments and uses a consistent framework to evaluate the experiments and determine with greater certainty the extent to which a reemployment bonus can affect economic outcomes. Bonus offers in each of the experiments generated statistically significant but relatively modest reductions in UI receipt. Since the estimated impacts on UI receipt were modest, the reemployment bonuses did not generate the UI savings necessary to pay for administering and paying the bonuses. Hence, contrary to earlier findings from a bonus experiment conducted in Illinois, findings from the Pennsylvania and Washington experiments strongly suggest that a reemployment bonus is not a cost-effective method of speeding the reemployment of UI claimants

Mirror symmetry breaking as a problem in dynamical critical phenomena

The critical properties of the Frank model of spontaneous chiral synthesis are discussed by applying results from the field theoretic renormalization group (RG). The long time and long wavelength features of this microscopic reaction scheme belong to the same universality class as multi-colored directed percolation processes. Thus, the following RG fixed points (FP) govern the critical dynamics of the Frank model for d<4: one unstable FP that corresponds to complete decoupling between the two enantiomers, a saddle-point that corresponds to symmetric interspecies coupling, and two stable FPs that individually correspond to unidirectional couplings between the two chiral molecules. These latter two FPs are associated with the breakdown of mirror or chiral symmetry. In this simplified model of molecular synthesis, homochirality is a natural consequence of the intrinsic reaction noise in the critical regime, which corresponds to extremely dilute chemical systems.Comment: 9 pages, 3 figure

REDUCING BLACKBIRD DAMAGE TO NEWLY PLANTED RICE WITH A NONTOXIC CLAY-BASED SEED COATING

At 3 sites in Chambers County, Texas, the estimated sprout loss in 1-ac plots sown with clay-coated rice seed averaged 17.0% compared to 36.5% in adjacent 1-ac control plots. In one field, bird use of the control plot was 14 times that of the treated plot. Average feeding rates of red-winged blackbirds (Agelaius phoeniceus) were 1.5 seeds/min and 8.4 seeds/min in the treated and control plots, respectively. Roadside counts of territorial male redwings and evening flightline counts of birds going to roost indicated a depredating population consisting mainly of nonbreeding, roosting birds early in April with increasing proportions of breeding birds as the rice-planting season progressed. The results of this study are consistent with previous laboratory findings and with predictions from foraging theory. Further development and field testing of the seed coating will be required before the technique becomes generally available as a method for reducing bird damage to sprouted rice
