Disentangling the relations between human migrations and water resources is relevant for food security and trade policy in water-scarce countries. It is commonly believed that human migrations are beneficial to the water endowments of origin countries for reducing the pressure on local resources. We show here that such belief is over-simplistic. We reframe the problem by considering the interna...

The electrocardiograms of ambulatory patients have been monitored over the telephone by staff of the intensive cardiac care unit using equipment in the unit. Telephone monitoring is a useful way of diagnosing transient symptomatic arrhythmias and a reliable aid in supervising the patient's rhythm at the beginning or end of treatment. The doctor has direct contact with the patient at the time of...

A n encouraging increase i n the knowledge of leprosy has been found in traditional healers after training has been given . Evaluation was by preand post-training questionnaires to which scores were assigned. Their role in leprosy care at the community level i s also being discussed . The traditional healer is part and parcel of the social milieu where he commands respect and has an intimate re...

Long-term water quality records for assessing natural variability, impact of management, and that guide regulatory processes to safeguard water resources are rare for California oak woodland rangelands. This study presents a 20-yr record (1981-2000) of nitrate-nitrogen (NO(3)-N) and suspended sediment export from a typical, grazed oak woodland watershed (103 ha) in the northern Sierra Nevada fo...

19. ABSTRACT (Continue on reverse if necessary and identify by block number) This study develops a model for measuring productivity in a large scale systems acquisition and development agency within the Department of Defense using the Analytic Hierarchy Process (AHP). Fourteen objective factors were identified and weighted to develop the relative importance of the primary determinants of produc...

Navigating any complex set of information resources requires tools for both browsing and searching. A number of tools are available today for using Internet resources, and more are being developed. This article reviews existing navigational tools, including two developed at the Yale University School of Medicine, and points out their strengths and weaknesses. A major shortcoming of the present ...

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...
