Responsetime and its significance in medical emergencies
Geographers have been increasingly involved in emergency medical-services planning. Of particular importance has been the application of location-optimizing models that minimize ambulance-responsetime. There has been little research
on the importance of responsetime and its clinical impact. Responsetime is confirmed as a determinant of patient outcome by the use of emergency medical system in Seattle as a case study.
The response of saltation to wind speed fluctuations
The AA. present direct measurements of the responsetime obtained from several field experiments. The sand transport was studied using 6 small microphones arranged in a vertical profile and collocated with a sonic anemometer, a webcam and a cup
. The transfer function can be established using an exponential function with a time constant or characteristic responsetime without time shift. The responsetime fluctuated between zero and 1.5 seconds depending on the turbulence intensity, the saltation

In order to investigate the impact of catchment responsetime on sediment flux, the AA. integrated a spatially-lumped numerical model PaCMod, with new routines simulating the evolution of landscape morphology and erosion rates under tectonic
, and investigated the impact of catchment responsetime on stratigraphy, using both synthetic scenarios and a real world system (Fucino Basin, central Italy). Their results demonstrate that the differential response of geomorphic elements to tectonic and climatic

, such as delayed response and/or cumulative effects, may affect morphological responses, making them capable of representing relaxation paths and times for a range of morphological response variables, whatever their initial states. To test their utility, the models
The framework includes 3 morphological response models, each developed from the fundamental rate law, which has the form of an exponential decay function. These models consider the possibility that characteristic behaviours of the fluvial system
in the framework were applied to simulate the sequence of geomorphological responses to disruption observed in selected rivers with well-documented histories of morphological perturbation, adjustment and recovery. The results demonstrate that the models
in the general framework can successfully simulate temporal and spatial patterns of morphological response in the fluvial system under a range of different circumstances.

Assam-Bengal relations : from the earliest times to the twelfth century A.D.
with reasons for such trends and their resultant reaction on the people at large. In response to the demand, Assam-Bengal relations were marked by conflicts as well as cooperation, at time unwittingly. - (GL)
The work deals with the varied aspects of the life of the people of the two regions, Assam and Bengal, from the pre-historic time till the end of the twelfth century AD. Similarities and differences that marked the two geographical regions are shown
This paper examines the scale linkage problem with respect to biogeomorphology at time scales intermediate between the evolutionary and the process-response, i.e., at time scale appropriate to landscape evolution. First, the A. presents several
theoretical perspectives on scale linkage between geomorphic and ecological (principally vegetation) processes and responses. Then, he will apply them to problems on the coastal plain of the southeastern United States.
Responsetime of an atmospheric general circulation model to changes in ocean surface temperature. Implications for interactive large-scale atmosphere and ocean models
Tree-growth response to Enso events in the central Colorado Front Range
are used to determine if ENSO-related climatic effects are detectable in tree-ring width patterns in the central Colorado Front Range. The form of the tree growth response is identified and the variability of the influence of these events on tree growth
This paper examines the likely response of coral reefs to future sea-level change over the time scale of 102 years, in the light of what is known of reef growth rates and reef response to sea-level change in the historical record, especially since
the late glaciation, and of the contemporary growth rates of reefs. Given the present imprecision of attempts to estimate future sea-level rise, the A. suggests broad response rates of reefs to various potential sea-level scenarios.
Last of the Real Geordies ? White masculinities and the subcultural response to deindustrialisation
In this historical ethnography, the A. investigates how a group of young white men are negotiating the transition to a postindustrial society. Their subcultural practices are seen as complex, materially orchestrated responses to the new times

Temporal and spatial response characteristics of vegetation NDVI to the variation of temperature and precipitation in the whole year, spring, summer and autumn was analyzed from April 1998 to March 2008 based on the SPOT VGT-NDVI data and daily
temperature and precipitation data from 205 meteorological stations in eastern China. The results indicate that as a whole, the response of vegetation NDVI to the variation of temperature is more pronounced than that of precipitation in eastern China.
