We build a theory of prosocial behavior that combines heterogeneity in individual altruism and greed with concerns for social reputation or self-respect. The presence of rewards or punishments creates doubt as to the true motive for which good deeds are performed, and this 'overjustification...

Accident costs are an important component of the external costs of traffic, a substantial part of whichis related to fatal accidents. The evaluation of fatal accident costs crucially depends on theavailability of an estimate for the economic value of a statistical life. The aim of the...

In almost all cases, the transport industry has adopted safety management systems (SMS) in response to a regulatory initiative. SMS vary dramatically across transport modes and jurisdictions - often because of the influence of different legacy regulatory programmes, and the attendant cultures....

This paper discusses obstacles faced in implementing SMS and uses concrete examples to show how to overcome them across all modes of transport (air, maritime, rail and road) in leading countries, particularly ITF member countries. The difficulties and problems in implementing SMS can originate...

System resilience is the ability for complex, dynamic-adaptive socio-technical systems to absorb and rebound from trauma or stress, and to avoid "jousting with dragons" where results are uncertain and often fatal. In a safety context, the term "dragons" originates from Professor David Woods at...

Since every Safety Management System (SMS) is intended to provide a framework by which an organisation manages risk, it is inevitable that accident investigators will take a close interest. The good investigator will always want to understand how the SMS was intended to control risk and how this...

The widespread use of pesticides in agriculture provides a particularly complex pattern of multidimensional negative side-effects, ranging from food safety related effects to the deterioration of farmland ecosystems. The assessment of the economic implications of such negative processes is...
