Aerial bombardment has been an important component of counterinsurgency practice since shortly after it became a viable military technology in the early twentieth century. Due to the nature of insurgency, bombing frequently occurs in and around settled areas, and consequently it tends to generate many civilian casualties. However, the effectiveness of bombing civilian areas as a military tactic remains disputed. Using data disaggregated to the level of the smallest population unit and measured at multiple points in time, this article examines the effect of aerial bombardment on the pattern of local control in the Vietnam War. A variety of estimation methods, including instrumental variables and genetic matching, show that bombing civilians systematically shifted control in favor of the Viet Cong insurgents. 相似文献

Proportionality is widely accepted as a necessary condition of justified self-defense. What gives rise to this particular
condition and what role it plays in the justification of self-defense seldom receive focused critical attention. In this paper
I address the standard of proportionality applicable to personal self-defense and the role that proportionality plays in justifying
the use of harmful force in self-defense. I argue against an equivalent harm view of proportionality in self-defense, and
in favor of a standard of proportionality in self-defense that requires comparable seriousness and takes into account the
wrong, as opposed simply to the harm that the victim is fending off. I distinguish the standard of proportionality in self-defense
from proportionality in circumstances of necessity, and I discuss whether proportionality is an internal or an external constraint
on the right of self-defense. 相似文献

This article examines an underground but emergent neo‐liberal initiative in US cities, historic preservation. A focus on Chicago's programme highlights this as a complex cultural project. The focus is on how narrativists of this programme use imagined mental spaces in discourse to constitute a programme‐ and neo‐liberal‐supporting cultural content for common consumption. The results suggst that this neo‐liberal programme offers elaborate renditions of spatially infused heroes, villains, victims and unmistakable forces that function as cultural frame. This constituting, the study concludes, is crucial to bolstering assertions about the importance of this programme and the need for neo‐liberal restructuring 相似文献
