Correspondence "On Scoring Rules in Subjective Assessment"
(1977) Morse, Joel N.
Outpatient Requests, Initial Sessions and Attrition
(Sage, 1978) Zisook, Sidney; Hammond, Roger; Jaffe, Kenneth; Gammon, Elizabeth
Treatment attrition in a psychiatric outpatient department was evaluated. Of eighty-two consecutive new patients, fifty-three (65%) showed up for a second appointment while twenty-nine (35%) failed to return. None of the demographic variables or specific categories of patient requests differentiated continuers from non-continuers; nor was attrition significantly influenced by feeling one's problems were understood, symptomatic improvement or receiving the kind of intervention originally desired. Treatment continuers were more likely to have been referred by other hospital clinics or psychiatric care facilities, and more often had previous outpatient contact, but these differences did not reach statistical significance. The only outcome measures significantly related to continuation were: perceiving one's feelings understood in the initial session, feeling satisfied with the interview, and planning to return for the next appointment. Theoretical and practical implications of these findings are discussed.

Medical noncompliance
(1980) Zisook, S; Gammon, Elizabeth
Increasingly recognized as a major medical health problem, non-compliant patient behavior remains on e of the least understood and most frustrating phenomena facing today's physicians. Although no single characteristic of behavior adequately defines the potential non-complier, a variety of factors raises the index of physician suspicion. This papaer examined four general categories affecting non-compliant behavior: patient factors, illness factors, therapeutic regimen factors, and physician-patient interaction factors. Based on these elements, a set of management implications is defined and discussed as possible deterrents to non-compliant behavior.
Reducing the Size of the Nondominated Set: Pruning by Clustering
(Computers and Operations Research, 1980) Morse, Joel N.
The multicriterion_ simplex methods of Evans and Steuer(!} and Yu and Zeleny[2) have encouraged model builders to consider matrix criteria. When conflicting objectives are simultaneously considered, there is no such thing as an optimum solution. Rather, a preferred class of basic feasible solutions called the nondominated set results. Since this set can be extremely large, some means must be found to prune it. Steuer[3] has proposed a filtering method. Another mechanistic aid to the decision maker · (DM), based on cluster analysis, is presented in this paper. The idea is to portray the nondominated set N by a representative subset. Cluster analysis partitions N into groups of relatively homogeneous elements. In this research I added a very general evaluative criterion: minimum redundancy. Since there is a threshold of resolution beyond which the OM cannot perceive the difference between two very similar solution vectors, there is little point in making him waste time processing all of N in the search for a final solution. Two forms of cluster analysis are tested - direct clustering and hierarchical clustering. Within the group of hierarchical methods there are eight algorithms. In the present application the two worst things that could happen are clusiers that "chain" and outlying vectors (the residue set) that are obscured. Taking account of these two undesirable outcomes, three algorithms worked best on the particular data used Ward's Method, the Group Average Method, and the Centroid Method. The hierarchical methods are recommended over direct clustering. {However, some similarity between direct and hierarchical clustering is discovered.) Hierarchical clustering serves to minimize redundancy, and thereby reduces the chance that the selection of a final solution will stress the decision maker beyond his information endurance. The concepts stressed in this paper are very similar to those expressed in Tom[4]. This article presents computational experience with the cluster analysis which was developed independently by Torn, whose approach and mine will be combined under an algorithmic strategy called Two-Stage Pruning (TSP). TSP first reduces the nondominated set to a representative set. This set, in turn, is interactively manipulated until a decision evolves.
Flexibility and Rigidity in Multicriterion Linear Programming
(Springer, 1980) Morse, Joel N.; Lieb, EB
One justification for modeling with multiobjective linear programming (MOLP) is its ability to generate unique managerial information. One drawback of MOLP is the unwieldy nondominated set which it presents to the decision maker. Two new concepts for picking one element of this set are examined in this paper. Flexibility is a universal evaluative criterion which can yield a (partial) ordering of the points in the nondominated set. It is based on the natural desire of planners to choose strategies that are reversible. Rigidity is an inverse concept. It reflects the situation in which planners specifically do not want flexibility in the chosen alternatives. Rigidity has the potential of ordering the nondominated set. Flexibility fits naturally into a financial context. Portfolio selection, for example, is a problem where the frictional costs of changing a decision are readily seen to be brokerage fees. Therefore this data base was used for an empirical study of flexibility. Rigidity, however, does not lend itself so easily to a mathematical approach. It is expressed here in a loose geometrical way. Further research may lead to an algebraic index of rigidity.
Student evaluations of a required sex education course
(Association of American Medical Colleges, 1980) Gammon, Elizabeth; Zisook, S
Medical student response to a required sex education course at the University of Texas Medical School is reported. The results suggest that the students have an objective awareness of sexuality as an integral part of medicine, but are reluctant to admit interest and are uncertain where their knowledge will be utilized.
Drug treatment of depression. A classification system for agent selection
(Taylor & Francis Ltd, 1980) Zisook, Sidney; Hall, Richard CW; Gammon, Elizabeth
Depressive illness can be severe, debilitating, and life threatening, but it often responds well to medication. The appropriate agent and dosage depend not only on accurate diagnosis of the type of depression present but also on the age of the patient, previous response to various medications, concurrent medical conditions, other medications being taken, and potential side effects of the antidepressants being considered for treatment.
SETTING COUNTRY LIMITS FOR INTERNATIONAL LENDING
(Wiley, 1981) Morse, Joel N.
Management of a rare blood type: Oh"Bombay" in pregnancy
(The American College of Obstetricians and Gynecologists, 1981) Katz, AR; Ali, V; Ross, PJ; Gammon, Elizabeth
A rare blood type, Oh "Bombay," was observed in a 30-year-old Indian primigravida. The genetic mode of inheritance is discussed. The obstetric management, with anticipation for the need for blood transfusion, is outlined and the use of autotransfusion for patients with rare blood type is emphasized.

Compound Lotteries; Call Option Spreads in Black-Scholes Markets
(Springer, 1981) Morse, Joel N.
From the earliest days of risky utility theory decision, theorists have elicited information from decision makers by analyzing their reaction to elementary lotteries, or gambles. The Purpose of the process was to define a mathematical function which could yield an ordering on a set of risky objects of choice. The information processing demands on the DM were minimal; everyone has an intuitive feel for endpoints such as $0 and $100. The purpose of this paper is to develop a reliable means of ordering compound lotteries in which the unaided decision maker does not even know the endpoints. Since the ordering will occur in several dimensions, several concepts from multiple criteria decision making will be used.
Banking in a Volatile World: Setting Country Lending Limits
(Springer, 1983) Morse, Joel N.
Banks often make decisions in an organizational framework that attempts to control repayment problems by setting loan limits for each country. A formal mechanism for setting those limits will be proposed. Our motivation is twofold. From the point of view of the lending institution, a more formal decision making system may be desirable. For the purpose of bank regulation this research offers help in quantifying and comparing the risk levels of banks. Country risk analysis has traditionally tried to articulate all the risks associated with a country. This is suspect in light of modern financial theory which holds that investors are rewarded primarily for bearing systematic, or market risk. This paper suggests several measures of risk and reward in international lending markets. First we model this situation with a multicriterion linear programming problem. After finding some drawbacks of that approach we propose a simpler alternative which is consistent with the Capital Asset Pricing Model (Sharpe, 1981). Beta, a measure of systematic risk, is estimated for countries. It is used as an input to a series of constrained optimization problems whose output is country lending limits.
Portfolio Selection to achieve a target beta
(AFCET, 1984) Mcinish, Thomas H; Saniga, EM; Morse, Joel N.
Suppose an investor wishes to construct a portfolio of size k securities from a population of n securities (k≤n) such that a particular portfolio or target beta (β p ) is achieved. Since β p is a random variable, there will be some difference between a portfolio’s realized beta and the target beta. We investigate the problem of finding the combination of k securities that minimizes the variance of β p , or equivalently, minimizes the probability of a particular difference in target and realized beta. We also seek answers to a number of related questions. These are concerned with the effect on the variance of β p of naive selection of securities, of the choice of k, and of the presence of a risk-free asset. We also examine the characteristics of securities included in the optimal portfolio.
A Multiobjective Expert System for Suppliers of Out-of-the-Money Options
(Springer, 1984) Morse, Joel N.
The proliferation of telecommunications and computing capability has sparked speculation about dispersing work. The electronic cottage industry approach has potential in the area of office and professional services. This paper proposes that certain functions of a centralized financial market can be decentralized. To relocate an element of an information processing system, its functions as well as its linkages must be duplicated. For that purpose, we draw on the theories of multiple criteria decision making (MCDM), artificial intelligence, and finance. On the trading floors of the world’s options exchanges, people called market-makers provide liquidity; when a buyer cannot find a seller, or a seller cannot find a buyer, these functionaries sometimes fill that void by trading for their own account. The physically grueling work of transacting on the exchange floor is often delegated to lower level employees. These people act with supervision from senior people, or perhaps with a set of decision rules formulated by the suppliers of capital. This paper will attempt to outline the features of an automated, remotely-sited system that emulates the market-making function which is normally performed on the site of centralized options exchanges. To make the task less formidable, I will concentrate on one very specialized market-making function, namely supplying uncovered out-of-the money options. The system is intended to promote useful communication between man and computer. Although it would be presumptuous to say that the system can learn, it can decide to query a human when certain conditions are present. From these situations, a richer array of decision rules will develop.
Jacques Bon-Homme and National Politics: Ethos and Audience in 17th- Century Political Pamphlets
(Proceedings of the Annual Meeting of the Western Society for French History, 1984) Sawyer, Jeffrey K.
A number of fundamental problems remain in the way of providing a comprehensive analysis of pamphlets and pamphleteerng in Old Regime France. Our incomplete knowledge of the sizes of editions, the mechanisms of distribution, and author-patron relationships is one set of problems. Another stems from the complexity of the the texts themselves. Pamphlet authors often cultivated a baroque style of rhetoric, twisting their into elaborate figures of speech, sometimes beyond recognition. Many pamphlets, at least in the early part of the seventeenth century, were intentionally written in colloquial speech, and some even contain parodies of southern dialects. Perhaps the most difficult obstacle to interpretation is the rich undercurrent of allusions and citations to other pamphlets, to popular customs, to learned books, and "the whole cultural baggage of the epoch," to use Denis Richet's marvelous phrase. One of the main questions that arises from these difficulties is the question of the audience. This is a particularly troubling issue for those who are concerned about the concrete political functions of pamphleteering. The identity of the "public" is especially obscure in the seventeenth century. Millions of pieces of pamphlet propaganda were published, yet there is precious little evidence as to who read them and how these readers reacted. Occasionally, we can learn from diplomatic correspondence that this or that pamphlet caused a reaction among high-level politicians. But what about the larger audience for whom the pamphlets were presumably written? The evidence available about patterns of literacy suggests that the readers were predominantly urban, but this is hardly a very satisfying solution to the problem of establishing the audience for printed propaganda.

Intervalling Effects in Hong Kong Stocks
(Wiley, 1987) Larson, John C; Morse, Joel N.
This paper investigates the intervalling-thinness effect in the Hong Kong stock market and compares the results with previous studies of United States and French data. The approach follows the three pass technique of Cohen, Hawawini, Maier, Schwartz, and Whitcomb. Various functional forms of an intervalling bias decay function are analyzed, both in the aggregate and for individual stocks. Careful modeling of the flattening of the beta profile at a finite interval value leads to robust estimated asymptotic betas.
A unified architecture for intelligent DSS
(IEEE, 1988) Teng, James TC; Mirani, Rajesh; Sinha, A
A unified architecture for an intelligent decision-support system (IDSS) is presented. The incorporation of the central intelligence manager (CIM) in the architecture makes the system intelligent. The CIM comprises an inference engine (IE) and an intelligent supervisor. The IE, which serves as a gatekeeper, is a program responsible for adding and deleting beliefs and making inferences. The intelligent supervisor acts as an interface to the IE; it is responsible for directing communications inside the IDSS. A knowledge-acquisition subsystem has also been incorporated to facilitate knowledge representation.
