The problem is how to translate limited and uncertain knowledge about the future environment into operational strategic policy decisions. Because the strategic policy decisions must be made with a long time perspective in mind (10 to 10 years), planners tend to formulate strategies which are overly broad. A solution to the broad and uncertain approach is to employ a system that relys upon the use of the infrastructure. When the infrastructure is divided into permanent and complete societal functions, then specific opportunities can be presented to the organization. Examples of functional domains that may be relevant to strategic long-range planning are: industrial capabilities, pieces of legislation, regulation and training. Our knowledge about evolving world trends is usually available in functional terminology (i.e., the evolving “information society”, the “leisure society”, the “energy crisis”, and the “food crisis”, etc.) Knowledge about the future behavior of the Functional Domains may enable organizations such as governments and/or corporations, to create the required infrastructure for capitalizing on possible opportunities. 相似文献

The techniques of thin-layer chromatography, gas chromatography with electron capture detection, and gas chromatography/mass spectrometry were used to analyze hand swab extracts for the presence of nitroglycerine. Both the amount of nitroglycerine transferred to the hands after handling commercial explosives and its persistence were measured. Gas chromatography-electron capture detection was found to be the most accurate and sensitive technique for making such determinations, especially if the extract was partially purified by thin-layer chromatography prior to analysis. The lowest limit of detection was 10 ng of nitroglycerine, and residues could be detected over 20 h after handling the raw explosive. 相似文献

The bulk and surface refractive indices have been measured for 20 float window glasses, 20 non-float window glasses, 20 patterned window glasses and 20 toughened float windscreen glasses.The refractive index of the tin-contact surface of the float glasses was always greater than that of the bulk, typically by 0.002 (range 0.00053–0.00307). In contrast the refractive indices of the two surfaces and the bulk of the sheet window glasses were in agreement within accepted experimental error in each case. A number of patterned window glasses showed significantly different refractive indices between the plain and patterned surfaces, the largest difference obtained (0.00021) being an order of magnitude smaller than that found for a typical float glass.Nine of the 40 float glasses examined yielded abnormal fragments from the upper surface in the sense that they did not disappear at the match temperature of the bulk glass. The refractive index measured from these abnormal fragments for two of these glasses was lower than the refractive index from the bulk glass.The variation in the bulk refractive index for the sheet and float window glasses produced an estimated standard deviation (E.S.D.) of 1.2 × 10?5. However, the patterned glasses were nearly three times as variable (E.S.D. = 3.3 × 10?5) and the toughened float glasses were, on average, almost seven times as variable (E.S.D. = 8.0 × 10?5).The value of making surface as well as bulk refractive index measurements in routine casework is discussed in the light of the above results. 相似文献

Many of the conventional agarose phosphoglucomutase (PGM) subtyping systems presently in use fail to provide a good separation between the 1 + and 2- bands as well as the 2+ band and the more anodic moving bands. Use of a 1-mm-thick gel composed of 1% ISO GEL (FMC Corp.) and phosphate-citric acid gel and tank buffers with a pH of 5.3 provided exceptionally good separation between all four of the major subtyping bands. The additional criteria for this procedure is a voltage of 21 V/cm and a run time of 4 h. Utilization of this procedure using case samples of varied ages proved the reliability of the procedure. Also examined were the effects of several reducing agents on the enzyme band patterns and the use of this system for the simultaneous determinations of the adenosine deaminase (ADA), erythrocyte acid phosphatase (EAP), and adenylate kinase (AK) enzyme phenotypes. 相似文献
