Religionens teknik og teknikkens religion

ENGLISH ABSTRACT: This article seeks to utilize the German philosopher Martin Heidegger's notion of Gestell to establish an outline of the relation between religion and technique including media technique. According to Heidegger, tech-nique on the one hand serves as a means for Man. On the other hand technique al-so embeds Man in new relations as a standing reserve for something else. The arti-cle suggests that media technology has contributed to embed Man in religious and national distinctions. On this basis, the article presents an outline of different his-torical stages in which technology and especially media technology has had crucial consequences for embeding Man in religious and national distinctions. DANSK RESUME: I denne artikel opstilles en skitse af hvordan forholdet mellem religion og teknik, herunder medier kan begribes ved hjælp af Martin Heideggers begreb Gestell. Dette begreb skærper opmærksomheden på det forhold at teknik ik-ke kun er et middel for mennesket, men også indlejrer mennesket i nye relationer. Mennesket bliver via teknikken stillet til rådighed eller som Heidegger kaldte det en bestand for noget andet end sig selv i disse nye relationer. I det lange historiske perspektiv har teknikken og især medieteknikken bidraget til at indlejre mennesket og dets livsverden i en række nye sammenhænge, heriblandt det man med ud-gangspunkt i Jan Assmann kunne kalde forskellige former for religiøse, statslige og nationale distinktioner, der har spillet afgørende roller i menneskets historie. På denne baggrund opstiller artiklen en skitse over sammenhænge mellem medietek-nik og religionsformer

Comparison between Greenland ice-margin and ice-core oxygen-18 records

Old ice for paleoenvironmental studies retrieved by deep core drilling in the central regions of the big ice sheets can also be retrieved from the ice-sheet margins. The d18O-content of the surface ice was studied at 15 different Greenland ice-margin locations. At some locations, two or more records were obtained along closely spaced parallel sampling profiles, showing good reproducibility of the records. We present ice-margin d18O- records reaching back into the Pleistocene. Many of the characteristic d18O-variations known from Greenland deep ice-cores can be recognized, allowing an approximate time scale to be established along the ice-margin records. A flow line model is used to determine the location on the ice sheet where the margin-ice was originally deposited as snow. The Pleistocene-Holocene d18O-change at the deposition sites is determined by comparing the d18O-values in the ice-margin record to the present _18O-values of the surface snow at the deposition sites. On the northern slope of the Greenland ice sheet, the Pleistocene-Holocene d18O-change is c. 10 per mil in contrast to a change of 6-7 per mil at locations near the central ice divide. This is in accordance with deep ice-core results.We conclude that d18O-records measured on ice from the Greenland ice-sheet margin provide useful information about past climate and dynamics of the ice sheet, and thus are important (and cheap) supplements to deep ice core records
