Recent studies suggest that sand can serve as a vehicle for exposure of humans to pathogens at beach sites, resulting in increased health risks. Sampling for microorganisms in sand should therefore be considered for inclusion in regulatory programmes aimed at protecting recreational beach users from infectious disease. Here, we review the literature on pathogen levels in beach sand, and their potential for affecting human health. In an effort to provide specific recommendations for sand sampling programmes, we outline published guidelines for beach monitoring programmes, which are currently focused exclusively on measuring microbial levels in water. We also provide background on spatial distribution and temporal characteristics of microbes in sand, as these factors influence sampling programmes. First steps toward establishing a sand sampling programme include identifying appropriate beach sites and use of initial sanitary assessments to refine site selection. A tiered approach is recommended for monitoring. This approach would include the analysis of samples from many sites for faecal indicator organisms and other conventional analytes, while testing for specific pathogens and unconventional indicators is reserved for high-risk sites. Given the diversity of microbes found in sand, studies are urgently needed to identify the most significant aetiological agent of disease and to relate microbial measurements in sand to human health risk.
What! Yet another article on the Vietnam war! Don't we know enough about it by now to avoid repeating it? The answer is no. We ought to, but we don't. In time there will be probing studies based on the Pentagon Papers and as yet unpublished documents and memoirs. But presently available evidence strongly indicates that the reigning explanations are one-sided and incomplete. So overwhelming has been the compulsion to blame the war on the mistakes of the civilian decision-makers that the military responsibility for beginning and prolonging the war has been virtually ignored.
Once again the American public is subjected to reports about the sensational effects of bombing against North Vietnam and its offensive in the South. New guided, or “smart,” bombs and the hitting of targets far beyond anything authorized at the height of the 1965-68 campaign have led to spectacular claims for the efficacy of air power in blunting the thrust of North Vietnam's Easter offensive. The Pentagon emphasis is now almost exclusively upon the success of air power in achieveing military goals; far less is claimed, at least publicly,, for bombing as a means of ending the war.
When Dean Acheson was appointed Under Secretary of State in September, 1945, I. F. Stone wrote in The Nation: “He has been pro-De Gaulle, anti-Franco, strongly opposed to the admission of Argentina to the U.N., and friendly to the Soviet Union … of all the men now in the Departrrient, Acheson was by far the best choice for Under Secretary, and it is no small advantage to pick a man who already knows a good deal about the inner workings.” Stone went on to note that one of Acheson's strongest assets was “in his relations with Congress. He deserves a generous share of the credit for the passage of the Bretton Woods legislation, and he played no inconsiderable part in the Senate's approval of the Charter.” In order to placate Acheson's reactionary critics, Tom Connally reassured trie Senate that he would “never have voted for Mr. Acheson's confirmation [as Under Secretary] unless it had been implicitly understood that he would not have a predominant voice in foreign policy.”
