How does diffusion of civil war battles influence conflict termination? Recent advances in civil war literature have found that battle dynamics shape conflict termination by affecting the intra-conflict bargaining between disputants. This article extends the theoretical perspective and argues that how battles diffuse matters in determining conflict termination. While battlefield dynamics should in principle reveal previously unavailable private information, the relevance of information-revealing effect depends on the diffusion patterns of battles. The persistent, and possibly battle-exacerbated, commitment problem can also alter the prospects of conflict termination. We test the argument by distinguishing two distinct diffusion patterns of battles: distant and proximate. The empirical results reveal that distant diffusion, but not proximate diffusion, of battles makes civil conflicts less likely to terminate. The analysis also demonstrates that incorporating diffusion dynamics significantly improves our ability to predict conflict termination.

Streptomycin-phosphorylating enzyme was reported previously to be produced in mycelium of Streptomyces griseus HUT 6037 at late stage of growth. In the present investigation, this enzyme was purified 200 times as high in specific activity as cell-free extract by means of salting out, chromatography on DEAE-Sephadex A-25 and gel filtration with Sephadex G-100. This enzyme was most stable at pH 8. 0 and required 10-2M Mg2+ in the reaction mixture for the highest activity. It lost the activity by heat treatment at 40°C for 15 min in absence of the substrate. Mutant cultures were prepared on productivity of or tolerance to streptomycin, and their capacity to produce streptomycin-phosphorylating enzyme was examined. The cultures which had low to no capacity to produce streptomycin produced a small amount to none of the enzyme, suggesting that production of the streptomycin-phosphorylating enzyme had some correlation with streptomycin productivity of the culture.• But no definite correlation was observed between productivity of the enzyme and the capacity to tolerate streptomycin.
