Sociotechnical Changes Brought about by Electronic Medical Record
This paper provides analysis of a 3-year longitudinal ethnographic study following the gradual adaptation of an Electronic Medical Record (EMR) in a community health centre in Canada. Adopting a sociotechnical perspective, I follow the EMR and the work practices as they undergo continuous modifications and I identify changes that are brought about by the EMR. Findings from this research show es...

متن کاملRapid Changes in Permeability of Cell Membranes to Water Brought About by Carbon Dioxide & Oxygen.
on the permeability of protoplasmic membranes to water. Our experimental tissue was the hypocotyl of Helianthus annuus. We have observed the effect of such factors on the permeability of the cells toward water passing both in the inward and in the outward directions. The rate of entry of water into uniform segments of tissue is a function of A, the difference in diffusion pressure deficit (DPD)...
متن کاملChlorophyll fluorescence quenching by xanthophylls
The interactions of the xanthophylls zeaxanthin, antheraxanthin and violaxanthin with chlorophyll, which are relevant for the chlorophyll fluorescence quenching in the non-photochemical quenching (NPQ) process in green plants, are investigated by means of quantum chemical methods. In particular, we use a hybrid approach consisting of time-dependent density-functional theory (TDDFT) and configur...
متن کاملReversible Changes in the Susceptibility of Mice to Bacterial Infections Ii. Changes Brought about by Nutritional Disturbances
In confirmation and extension of earlier results from this laboratory (3, 5, 18), it will be shown in the present paper that the susceptibility of mice to a number of bacterial pathogens can be markedly increased by depriving the animals of food, or feeding them inadequate diets, just prior to infection. Evidence will be presented furthermore that the change in susceptibility thus induced is re...
