Uncertainty in conceptual model structure and in environmental data is of essential interest when dealing with uncertainty in water resources management. To make quantification of uncertainty possible is it necessary to identify and characterise the uncertainty in geological and hydrogeological data. This paper discusses a range of available techniques to describe the uncertainty related to geo...

As the supply of physicians grew during the 1970s, medical and surgical specialists diffused into smaller communities. In 1979, nearly every town with a population of more than 2,500 had ready access to a physician. The overall pattern of physician distribution was quite similar in the four disparate geographic regions chosen for study. The data strongly suggest that competitive forces play a m...

Lakes are disproportionately important ecosystems for humanity, containing 77% of the liquid surface freshwater on Earth and comprising key contributors to global biodiversity. With an ever-growing human demand for water and increasing climate uncertainty, there is pressing need for improved understanding of the underlying patterns of natural variability of water resources and consideration of ...

Accurately mapping and monitoring glacier changes over decades is important for providing information to support sustainable use of water resource in arid regions of northwest China. Since 1970, glaciers in the Eastern Altun Mountains showed remarkable recession. Further study is indispensable to indicate the extent and amplitude of glacial change at basin and individual glacier scale. In this ...

People in the Arctic face uncertainty in their daily lives as they contend with environmental changes at a range of scales from local to global. Freshwater is a critical resource to people, and although water resource indicators have been developed that operate from regional to global scales and for midlatitude to equatorial environments, no appropriate index exists for assessing the vulnerabil...

Uses of symbolic resources can be seen as dialogical processes: they take place in a cultural world constituted by semiotic exchanges; they can lead people to interact; and as artefacts, they contain echoes of many other voices. The article proposes to consider traditional Talmudic study as a paradigmatic dialogical situation, in which scholars learn to use traditional texts as resources to add...

Intensive care medicine (ICM) is unique in that it deals with the most severely ill patients in almost all fields of medicine. It is demanding in all aspects from a theoretical, practical, co-operational and personal perspective. It is also characterised by a rapid development in diagnostic and treatment options. Furthermore, the organisational and manpower characteristics of European healthcar...
