Exhibits 2-5 and 2-6 are modified sample lists of programs and elements for an actual company (here called Xmple, Inc.) drawn from the files of Arthur D. Little. These are in addition to the PSM requirements shown in Exhibit 2-4. You should develop similar lists for your company. These can usually be obtained from PSM and ESH manuals or the specialist staff who support the programs and elements. Be careful to make sure you understand the scope of each program, as the titles can sometimes be a little misleading. For example, spill response may cover only measures to be taken to stop further spillage, while containment and clean-up are covered under emergency response.

The FORTRAN program ARTHUR (Harper et al. 1977)—running on main frame computers at this time—comprised all basic procedures of multivariate data analysis and made these methods available to many chemists in the late 1970s.

The Bayesian analysis of BACLASS (a program of ARTHUR), where the decision function is obtained from the product of the marginal PDs computed by the smootted (symmetrical or skewed) histograms, may apparently be used with skewed distributions, without preliminary transformations of the original variables. 

Because of the correlation between variables, univariate methods can select some variables that give the same information. The decorrelation method, used in the program SELECT of the software package ARTHUR, selects the first variable according to Fisher ratio, then this variable (let it be xp is subtracted from the remaining variables ... 

We would like to express appreciation to staff members at SRI International and at Arthur D. Little, Inc., who performed the experimental work on these programs, and to the National Institute for Occupational Safety and Health for its support. The methods developed in these studies are published in the NIOSH Manual of Analytical Methods (6). 

The evaluation of diffusion samplers reported in this paper was initiated as an internal project at Arthur D. Little, Inc., to develop for ourselves a base of data which would help us to judge the utility of diffusion samplers in our work. Diffusion samplers were purchased from the two firms active in the marketplace when the field study began (early 1979), Abcor and 3M. A program was devised wherein, during each of approximately 50 surveys being undertaken in plastic fabrication plants, four to six diffusion samplers would be exposed, each adjacent to a charcoal tube personal sample. At the conclusion of the field sampling, a data base of over 100 pairs of samples (each pair including a diffusion sample and a charcoal tube sample) had been compiled for each of the two diffusion samplers.

ARTHUR Infometrix, 2200 Sixth Ave. 833, Seattle, Wash. 98121, USA cca 7000. This package of Fortran programs has been developed at the Department of Chemistry of the University of Washington, Seattle. For many years it was the most widely used program for PCA and other pattern recognition applications in chemistry. ARTHUR has been written for mainframe computers, but also PC-versions are used (e.g. TNO CIVO Institute, P.O.Box 360, NL-3700 AJ Zeist, The Netherlands). An overview of ARTHUR is given in Wolff and Parsons (ref. 14). 

Arthur Bienenstock I should say that about 7 or 8 months ago in the White House, we very quietly had a meeting of the relevant people from industry—human resource officers, people dealing with these issues—where we just sat around the table and went over what is working and isn t working. We intend to do that more and more just because of this sort of situation, and we are facing it ourselves. We had to review every program that we had to see whether it was constitutional and would hold up under... 

From the chemists viewpoint the technique has been pioneered by Kowalski, who has described it very clearly in benchmark papers30 31) reviewed it32), demonstrated that it is equally applicable to the classification of the clays used in ancient pottery and to the identification of oils from spillage incidents 33), and has made his set of computer programs ARTHUR available to the scientific community. Many others, have been active within the area and their work has been comprehensively reviewed by Kryger341 and Varmuza35) who has also described virtually all of the techniques which have been applied. All of these have important features in common ... 

The authors would like to thank Diane K. Rindt for the x-ray diffraction work and Arthur L. Severson for x-ray fluorescence analysis. Mr. Roaldson acknowledges support from Associated Western Universities, Inc., as part of their summer undergraduate research participation program. 

Shortly after Arthur Pardee came back to Bushnell fi"om the Dry Tormgas Islands, he left and joined a war project in the Radiation Laboratory at Berkeley. Captain Nolen was furious. He said Pardee had abandoned real war research at Bushnell and fled to ivory tower research in the University at Berkeley. Only later could it be said that Pardee had left Florida to work at Berkeley on the nuclear bomb program.
