Ethnic conflict: geography of

Much ethnic conflict is territorially based. From a geographical perspective, ethnic conflict can be viewed at three scales—the inter-state, the intra-state and the micro, predominantly urban level. However conflicts at the three scales are intimately connected and interact with each other. The outcomes of conflict can produce secession, or at least some degree of separation of the groups concerned. Again, this can be viewed across a range of scale levels. A number of territorially based solutions or at least means of regulating ethnic conflict can be delineated—territoriality, dominance, and mutuality.

Effect of Target Polarization in Electron-Ion Recombination

We present results of a study of the effect of target polarization on electron-ion recombination, and show that coherent radiation by the target electrons gives a large contribution to the recombination rate. It significantly modifies the nonresonant photorecombination background. A procedure has been devised whereby this contribution can be evaluated together with the conventional radiative recombination, independently of the dielectronic recombination component. Numerical results are presented for Zn2+, Cd2+, Sn4+, and Xe8+, showing up to an order-of-magnitude enhancement.

Electron impact ionization of hydrogen-like molybdenum ions

The electron impact ionization cross sections of hydrogen-like molybdenum ions were measured with an electron beam ion trap at the electron energies of 49.4, 64.4 and 79.6 keV The results are 2.82(22) x 10(-23), 3.13(29) x 10(-23) and 3.23(51) x 10(-23) cm(2), respectively. These results are compared with the experimental results measured previously. The agreement with the results obtained with, scaling formulae is also discussed.
