Political terrorism and the size of government: A positive institutional analysis of violent political activity
Political terrorism has been described as violent political behavior primarily designed to generate fear in the community, or a substantial part of it, for political purposes.' Political terrorism is distinguished from revolution in that the immediate objective of terrorist acts is intimidation rather than the overthrow of the existing government. Terrorism is a form of political extortion. Positive theories of crime 2 and extortion 3 assume that individuals will act to maximize some objective function subject to existing social or legal constraints. However, there is no parallel to these positive approaches aimed directly at the subject of political terrorism. Existing literature (hereafter referred to collectively as traditional literature) is dominated by the writings of psychologists, sociologists, and historians. Within these works, political purposes are typically defined as ideological in nature. As a result, political terrorists are assumed to be ideological zealots, willing to kill and be killed in order to further 'the cause'. Within this context positive analysis becomes difficult. Few analysts can rationalize such extreme behavior. As a result, traditional studies are forced to search for typically unobservable psychological and socio-economic characteristics as explanations for violent behavior. Frequently cited causes of political terrorism are lack of self-esteem (Kaplan, 1978: 245), emancipation afforded women (Dobson and Payne, 1979: 51), economic and political alienation and relative depravation (Bassouini, 1975; Gurr, 1969 and 1970; Dollard et al., 1939; and Wilkinson, 1977). Terrorists are characterized as irrational (Wilkinson, 1977: 49) or insane (National Advisory Committee..., p. 20). The dominant theme in the existing literature is a call for expansion of
Working Paper No . 329 Terrorism and Business
Deterrence has been a crucial element in fighting terrorism, both in politics and in rational choice analyses of terrorism. However, there are two strategies that are superior to deterrence. The first one is to make terrorist attacks less devastating and less attractive to terrorists through decentralization. The second one is to raise the opportunity cost – rather than the material cost – for terrorists. These alternative strategies will effectively dissuade potential terrorists. It is here argued that they not only apply to society as a whole but can also usefully be applied by business enterprises. (96 words) JEL Classification: D74, H56, K42
Characteristics of Inversion Tubes under Axial Loading
A thin wall tube, when axially compressed over a radiused die, either inverts, or buckles or tears. The phenomena associated with the external or internal inversion of tubes of aluminium, copper, mild steel and brass are described and load-tube shortening curves are presented for speeds of compression between 0·05 in/min and 20 in/min; some results for high speed compression using a drop hammer are also described.Thickness changes during inversion are reported and experiments to establish the effect of die angle and die radius on the inversion load are given.For the inside-out inversion of tube, a simple theoretical analysis to predict the steady inverting load and the optimum die radius for a strain hardening material is given, the basic assumption being that no change in the wall thickness takes place.
