This study discusses some empirical findings on various computer and Internet-related crimes. An appropriate diffusion model was used that encompassed modeling of two opposite behaviors—imitation and deterrence acts. The model also is adequate for handling sparse data. The model was used to analyze various types of attack. The results shows that different types of attacks follow different types...

Deterrence-based initiatives form a cornerstone of many road safety countermeasures. This approach is informed by Classical Deterrence Theory, which proposes that individuals will be deterred from committing offences if they fear the perceived consequences of the act, especially the perceived certainty, severity and swiftness of sanctions. While deterrence-based countermeasures have proven effe...

Deterrence has been a crucial element in fighting terrorism, both in actual politics and rational choice analyses of terrorism. But there are superior strategies to deterrence. One is to make terrorist attacks less attractive. Another to raise the opportunity cost – rather than the material cost – to terrorists. These alternative strategies effectively dissuade potential terrorists. The strateg...

Behavioural responses of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), a generalist, cell sap-feeding insect species with piercing-sucking mouthparts, after continuous exposure to two deterrent secondary plant compounds are investigated. We compared in choice assays on bean leaf discs, the settling, feeding, and oviposition preferences of F. occidentalis females that had no e...

A new line of nuclear winter research shows that even small, regional nuclear wars could have catastrophic global consequences. However, major disarmament to avoid nuclear winter goes against the reasons nuclear weapon states have for keeping their weapons in the first place, in particular deterrence. To reconcile these conflicting aims, this paper develops the concept of winter-safe deterrence...

Geographic variation in resource use can produce locally adapted populations that exhibit genetic and phenotypic divergence. In the bird-winged grasshopper (Schistocerca emarginata = [lineata]), we investigate whether genetic data exist in accordance with geographic variation in resource (host) use and coloration. In Texas, juvenile grasshoppers feed almost exclusively on one of two host plants...

This paper provides a sketch of a contractarian approach to punishment, according to a version of contractarianism one might call “rational contractarianism,” by contrast with the normative contractarianism of John Rawls. Rational contractarianism suggests a model according to which rational agents, with maximal, rather than minimal, knowledge of their life circumstances, would agree to the out...
