London''s health care problems, particularly underfunding, are mirrored in other major cities in the United Kingdom and abroad. None has found the perfect solution, but the debates on the Tomlinson report provide an opportunity to review how to manage the three major areas of service provision, medical education, and research in London. Mr Robert Maxwell suggests that some aspects of the successful ambulatory care initiative in New York could be adapted by the capital''s primary care providers while the secondary services might learn from the rationalisation of specialist services in Paris. 相似文献

The nature of institutions is nothing but their coming into being ( nascimento ) at certain times and in certain guises. Whenever the time and guise are thus and so, such and not otherwise are the institutions that come into being—Vico, The New Science. 相似文献

A comparative estimation of the coliform population of raw sewage, activated sludge, and the effluent derived therefrom revealed that raw sewage had a preponderance of Escherichia coli (75%), as compared with 25 and 30%, respectively, in sludge and effluent. Nitrogen-free mannitol-sucrose enrichments of activated sludge resulted in the isolation of Azotobacter agilis, Aerobacter aerogenes, Corynebacterium laevaniformans, and an Achromabacter species. Sludge had a large population of C. laevaniformans and A. aerogenes but not of Azotobacter. The bacterial parasites, Bdellovibrio and bacteriophages, were not active during activated-sludge treatment. A 10-fold reduction in phage content occurred after 2 hr of aeration, but the Bdellovibrio population was unaffected. 相似文献
