The article first describes characteristics of major infrastructure projects. Second, it documents a much neglected topic in economics: that ex ante estimates of costs and benefits are often very different from actual ex post costs and benefits. For large infrastructure projects the consequences are cost overruns, benefit shortfalls, and the systematic underestimation of risks. Third, implications for cost–benefit analysis are described, including that such analysis is not to be trusted for major infrastructure projects. Fourth, the article uncovers the causes of this state of affairs in terms of perverse incentives that encourage promoters to underestimate costs and overestimate benefits in the business cases for their projects. But the projects that are made to look best on paper are the projects that amass the highest cost overruns and benefit shortfalls in reality. The article depicts this situation as ‘survival of the unfittest’. Fifth, the article sets out to explain how the problem may be solved, with a view to arriving at more efficient and more democratic projects, and avoiding the scandals that often accompany major infrastructure investments. Finally, the article identifies current trends in major infrastructure development. It is argued that a rapid increase in stimulus spending, combined with more investments in emerging economies, combined with more spending on information technology is catapulting infrastructure investment from the frying pan into the fire.

The AMANDA neutrino telescope has been in operation at the South Pole since 1996. The present final array configuration, operational since 2000, consists of 677 photomultiplier tubes arranged in 19 strings, buried at depths between 1500 and 2000 m in the ice. The most recent results on a multi-year search for point sources of neutrinos will be shown. The study of events triggered in coincidence with the surface array SPASE and AMANDA provided a result on cosmic ray composition. Expected improvements from IceCube/IceTop will also be discussed.

This paper looks at how a transnational movement of Roma, Sinti, Gypsies, Travellers, Jenische and Gitanos from all over Europe connected in the 1970s to combat european racism towards Gypsies and to struggle for equal rights. It is argued that the political success of the movement is difficult to assess. The cultural impact, however, was considerable. In a process of ´adaptation of tradition´ the emancipation movement successfully replaced racist notions of Gypsies with a transformed, romantic vision of Roma as an indian people in the diaspora. 

"La protagonista del racconto inedito Adriana di Federico De Roberto si offre come uno dei suoi più memorabili “Studi di donna”, colta sulla linea d’ombra del “maestoso declinare della sua bellezza matura”, e sullo sfondo altrettanto opprimente d’una provincia sordida, maligna e assatanata. Dopo più di un secolo d’oblio, intrappolato tra le maglie di una spietata autocensura, il racconto disperso si trascina dietro altri interessanti “documenti umani” che permettono di guardare con occhi nuovi anche un più celbre “ritratto di signora”, quella Teresa Uzeda dell’Illusione che non impegnò, alla luce di quanto riemerso, solo la fantasia dello scrittore catanese.
