The two ring road complexes of Gdansk
PublicationThe urban structure of Gdańsk city centre is determined by two ring road complexes. The first of them, the Gdańsk Ring, has been designed by Hermann Josef Stübben as a result of a defortification at the turn of the 19th and 20th centuries. This new modern zone of the city centre was destroyed like the rest of Gdańsk in the end of World War Two and had not been reconstructed as a result of de-Germanization of the Recovered Territories....

Quantitative Storytelling in the Making of a Composite Indicator
PublicationThe reasons for and against composite indicators are briefly reviewed, as well as the available theories for their construction. After noting the strong normative dimension of these measures—which ultimately aim to ‘tell a story’, e.g. to promote the social discovery of a particular phenomenon, we inquire whether a less partisan use of a composite indicator can be proposed by allowing more latitude in the framing of its construction....
