2 Of the many frustrations of any editor, surely, avoidable delay is the greatest. And this frustration is almost infinitely compounded when in the interim an unexpected death occurs. Professor Ferguson sent this manuscript as a draft; certain questions which he raised in the accompanying letter would normally have been resolved in the exchange of two or three letters or 'phone calls. I placed one call to learn he was ill; rather than press the query, I delayed. When next I 'phoned, I was shocked to learn of his completely unexpected and therefore all the more untimely death. Because the draft he sent contains so much of his own style and vigor, I have elected to print it in this incomplete form. The points he raised in his letter remain unclarified. In the face of this series of events, I have asked Professor Nell to undertake the task initially given to Ferguson. The two rarely saw things in the same way. Thus, the choice of Nell was not intended to finish Ferguson's incomplete assessment. I mention the foregoing simply to explain the unique treatment in these review essays. Of Charles Ferguson's death so little can be said-he was an ebullient souil, and a man of significant originality. -M. P.

Abstract This article presents information on evaluating alternative methods of accounting for long-term nonsubsidiary holdings of common stock. Long-term investments by one corporation (investor) in the common stock of another corporation (investee) can be classified in one of two basic categories according to the percentage of the common stock of the investee corporation held by the investor corporation. Holdings of more than 50 percent are classified as subsidiary holdings while holdings of 50 percent or less are classified as nonsubsidiary holdings. Under the cost method, "periodic investor income" consists of dividends received by the investor which are distributed from the investor's proportionate share of undistributed investee earnings accumulated since the acquisition of the investment. The book value of the investment on the investor's books, hereafter referred to as "investment carrying value," is periodically reduced by any dividends received in which distributions in excess of investee earnings since acquisition of the investment. Such dividends are referred to in this paper as "excess dividends." Finally, Opinion 18 states that a senes of operating losses of an investee or other factors may indicate that a decrease in value of the investment has occurred which is other than temporary and should accordingly be recognized.

This survey examines eight mathematical programming models of pattern classification. The paper determines the range of applicability and computational merits of each model. The flexibility and large sample properties of the models are also discussed. We find that six of the models produce decision rules that maximize a function we call the quality of a decision rule. The remaining two models minimize a weighted sum of errors.

The September 1971 issue of Operations Research contains an ORSA committee's report entitled “Guidelines for the Practice of Operations Research.” The issue also contains other material relating to a dispute concerning a specific operations research project. It occurred to me that members of The Institute of Management Sciences might well have an interest, not in the dispute, but in the Guidelines, since these are obviously closely related to the significance of the practice of applied management science. Many of the members of The Institute of Management Sciences over the years have had an intense interest in the meaning of “the scientific method” as it relates to management science, not only in the model building aspects of the science, but in the broader concerns which occur in applications.

The facts of increased institutional trading on the nation's securities markets are by now well known. On the New York Stock Exchange (NYSE), the six major institutional groups—insurance companies, investment companies, noninsured pension funds, nonprofit institutions, common trusts, and mutual savings banks, now own more than one-fourth of the market value of listed shares compared with less than 16 percent at the end of 1956. But, ownership is merely the tip of the perennial iceberg, since institutional trading of stock has become much more significant than institutional ownership. This fact is pointed up in the recent SEC Study of Institutional Investors. It shows that there has been a relatively slow increase in the share of outstanding stock owned by institutions in all markets, but the institutional share of trading has mushroomed.

General System(s) Theory (GST) has failed to deliver because of its own basic assumptions. Hierarchy compels us to impersonalize all social interaction, thus making it impossible to realize ourselves. Concreteness overemphasizes the single organization and determinism as well. Competition returns us to the mechanistic tradition GST initially sought to escape. Finally, GST remains tied to ?laws? of growth which promise only our destruction. American Indians knew better.

[The multi-period control problem analyzed assumes the data are generated by the simple regression model with an unknown slope coefficient. There is a tradeoff between stabilization and experimentation to learn more about the unknown coefficient. When parameter uncertainty is large, experimentation becomes an important consideration.]
