Telepresence-Enabled Maritime Archaeological Exploration in the Deep

Telepresence-enabled exploration of deep sea environments has developed over the past 30 years, providing access to archaeologists, scientists, and the general public to sites otherwise inaccessible due to depth. Pioneered through the inception of the JASON Project in the late 1980 s, telepresence missions have expanded to two dedicated ships of exploration, NOAA Ship Okeanos Explorer and exploration vessel Nautilus, and has been implemented on a series of opportunistic missions on other vessels. This paper chronicles the history of the use of telepresence for the exploration of shipwrecks in deep water as well as how this capability has allowed the public to engage with such missions. Broadening the scope of who can explore the deep sea, telepresence has also expanded what is observed and documented in the deep, which speaks to humanity’s use of the maritime world and an archaeology of discard through our material disposed of into the deep sea.     

Vom Denken in Analogien

Analogy as a scientific method has been criticized during the last decades; only for heuristic purposes it has been accepted. On the other side especially proportional analogies have a long tradition in European thought since Plato and Aristotle, for, as Aristotle puts it, analogies allow a connection between different and unbridgeable ontological areas. As examples for such connections the analogia entis of Thomas of Aquino and the Kantian Analogies of Experience are discussed. They give us hints for a new view of analogies, which during the Middle Ages were not only of heuristic value, but were accepted as a proof: Analogies do not only produce hypotheses, moreover, they build up new views of the world, they are the background of paradigms, for they create structures by introducing similarities and proportions.     

Economic Transformation in Eastern Europe: Its Genesis,Adjustment Process,and Impact on Developing Countries

ABSTRACT Increasing strains on self-sufficiency within the block of East European command economies resulted in the dramatic decision to change over to an economic system largely based on market forces. The painfulness of the ensuing transformation process will be mitigated somewhat by supportive economic policies of the West, including the European Community which is itself aiming at complete economic integration by the end of 1992. The consequences for the developing countries of these far-reaching policy changes in East and West are likely to be negative, at least in the immediate future. This is true for the volume of development assistance given by East and West, as well as for the export prospects of developing countries. Favourable effects might at best be expected in the longer run.     

The extent of farm desertion in central Sweden during the late medieval agrarian crisis: landscape as a source

The effects of medieval agrarian crisis on settlement and population were considered in a major interdisciplinary research project in Scandinavia during the 1960s and 1970s. Within this project, there were significant differences in methods used to calculate the extent of farm desertion between historians in the participating countries. The reliance on written source material within the Swedish team reflected the dominant approach amongst historians who made less use of map and landscape evidence than others. In this renewed investigation of the magnitude of farm desertion in the Late Middle Ages, focussing on the province of Jämtland in central Sweden, field survey of the physical landscape and some three thousand historical maps are used as evidence, alongside conventional written sources, such as official letters and taxation documents. The results indicate that the extent of farm desertion in medieval Sweden has been underestimated because Swedish scholars generally eschewed the use of the retrogressive method, which their Norwegian counterparts had been using since the 1940s. There is therefore good reason to reassess the desertion rates of medieval farms in other parts of Sweden as well, using traditional geographical source materials together with the documentary sources usually favoured by historians This may also hold for other parts of Europe as well. The rate of desertion is discussed in a wider context of settlement contraction and expansion in central and peripheral areas of Sweden, including the long drawn-out process of reclamation of the deserted farms (ödesbölen).
