Size distribution of particulate mercury by the roads and in the urban background conditions - preliminary study

Próbki aerozolu pobierano w Katowicach i Zabrzu, równolegle na stanowisku komunikacyjnym i tła miejskiego za pomocą 13-stopniowych impaktorów kaskadowych (DLPI fi rmy Dekati). Zawartość rtęci Hgp oznaczono metodą CVAAS (MA-2 fi rmy NIC). Rozkład masy Hgp względem wielkości cząstek miał zasadniczo charakter bimodalny. Główna wartość modalna rozkładu (maksimum) występowała w przedziale cząstek 0,4–1 μm (tzw. frakcja akumulacji). Natomiast druga mniejsza moda była zorientowana lokalnie i występowała w przedziale cząstek drobnych (0,108– –0,17 μm – Zabrze) lub grubych (2,5–4,4 μm – Katowice), zależnie od źródła pochodzenia Hgp.The aerosol was sampled simultaneously at two measurement sites (i.e. traffi c and urban background sites) in Katowice and Zabrze. The sampling was performed with 13-stage DLPI cascade impactors (manufactured by Dekati). The Hgp content was determined with the CVAAS method (MA-2 analyzer manufactured by NIC). The Hgp mass size distribution was generally bimodal. The main modal value of the distribution (maximum) was observed for the particle range of 0.4–1 μm (so-called accumulation fraction). The other lower mode was locally oriented and observed for fi ne (0.108–0.17 μm – Zabrze) or coarse (2.5–4.4 μm – Katowice) particles, which depended on the Hgp source

Schmitt e la logica paolina della decisione giuridica

Il mio articolo affronta la questione dell'uso politico della legalità e analizza la critica schmittiana della neutralizzazione politica degli ordinamenti. Cerca quindi di far luce sulla genesi dell'espulsione dell'eterogeneo nella comunità politica, per decidere se essa appartenga intrinsecamente al pensiero della decisione politica

From ethnic to republican integration: The discourse on the reform of German citizenship

Faist T, Gerdes J. Von ethnischer zu republikanischer Integration: Der Diskurs um die Reform des deutschen Staatsangehörigkeitsrechts. Berliner Journal für Soziologie. 2006;16(3):313-335.This article analyzes the political debate and the policy process leading up to the unusual outcome of the German Citizenship Law Reform in 1999 in comparative perspective. The reform provided a very liberal ius soli-introduction and at the same time kept a restrictive attitude toward dual citizenship. This somewhat contradictory outcome is essentially the result of a compromise between two opposing political camps holding quite different interpretations of the relationship between state and citizen, the function of citizenship law, and the integration of both immigrants and overall society. It is argued that the delay of citizenship law reform in Germany, at least during the last fifteen years, cannot be explained by means of an ethnic concept of nation, as many scholars have contended. Rather it is characterized by a persisting ideological conflict structure, which has been reinforced by institutional patterns of the political and legal system. The opposing views regarding the significance of citizenship are embedded within republicanism, stressing citizenship as activity on the one hand and citizenship as a right on the other hand. The two perspectives differ with respect to the functions of citizenship and the position of state and citizens within polities
