abstract this paper presents a quantitative account of vegetation–environmental factor relationships in arid rangelands. vegetation cover was recorded using braun-blanquet combined abundance-cover scale in each quadrat. within each quadrat, one profile was dug and soil samples being taken at 0-20cm and 20-100cm depths. under study physical-chemical characteristics included texture, lime, organi...

The metal ion co-ordination sites of many metalloproteins have been characterized by a variety of spectroscopic techniques and small-molecule model systems, revealing many important insights into the structural determinants of metal ion co-ordination. However, our understanding of this fundamentally and practically important phenomenon remains frustratingly simplistic; in many proteins it is es...

Subfossil biotic assemblages in surface sediments of lakes have been used to infer ecological conditions across environmental gradients.. Local variables are usually the major drives of assemblage composition, but in remote oceanic islands biogeographic filters may play a significant role. To assess the contribution of local and regional filters in the composition of subfossil diatoms and chiro...

A key problem for models of dialogue is to explain how conventions are established and sustained. Existing accounts emphasize the importance of interaction, demonstrating how collaborative feedback leads to more systematized, stable and arbitrary referential conventions. However, co-ordination in dialogue requires both co-ordination of content and of process. To investigate procedural co-ordina...

Abstract This article addresses current ambiguities and potential confusion around the language nature of vocation to ordination, focusing specifically on process by which that is discerned individual church. It suggests particular shape ordained ministry differentiates vocational discernment ordination from career choice. Drawing Ordination rite Church England, distinctive Christological, pneu...

OBJECTIVE To investigate the association between care co-ordination and use of the Emergency Department (ED) in older managed care enrollees. DESIGN Nested case-control with 103 cases (used the ED) and 194 controls (did not use the ED). PATIENTS AND METHODS Older patients with multiple chronic illnesses enrolled in a care management programme of a large group-model health maintenance organi...
