The Sphere of Influence

Abstract: This is a study of network representation: The data represent a set of interlocked directorates—specifically, the network in which the boards of major banks are interlocked with the boards of major industrials. The problem is to represent this network so as to organize it and describe its major outlines. Using an unfolding variant of smallest space analysis, the problem is solved by a spherical map: the “Sphere of Influence.” The sectors of the sphere represent similarly-linked corporations, and the relations among the sectors represent the relations among bank-industrial communities.

On factor representations and the c*-algebra of canonical commutation relations

Abstract: A newC*-algebra,A, for canonical commutation relations, both in the case of finite and infinite number of degrees of freedom, is defined. It has the property that to each, not necessarily continuous, representation of CCR there corresponds a representation ofA. The definition ofA is based on the existence and uniqueness of the factor type II1 representation. Some continuity properties of separable factor representations are proved.

Access to elements of a memorized list

Abstract: McGill UniversityThe & watched series of one, two, three, four, or six letters presented visually,one every 300 msec., and then decided if a probe letter, presented 600 msec,later, was or was not in the original list. Decision time increased with thenumber of letters in a series; the increase was more pronounced for YES thanfor NO decisions. Within the four- and six-letter sequences, there were pro-nounced primacy and recency effects. These results favor a theory that 5 hasdirect access to an internal representation of the probe letter and decidesYES or NO depending on its memory strength. They are inconsistent withtheories which hold that 5 scans through the series to discover whether theprobe is there.

Modes of representation of thought.

Abstract: ONSCIOUS THOUGHT REQUIRES REPRESENTATION of ideational and affective information. In dreams the visual mode of represenC tation predominates. In the waking thought of many adults the lexical mode of representation predominates, but is by no means exclusive. A psychoanalytic theory of thinking should include a model of the various possible modes of representation and the differing properties of each mode. Such a model would provide a conceptual tool for describing the formal properties of conscious experiences. In particular, such a model would be useful in describing shifts between modes of representation as they occur in streams of thought, in the development of thought in children, and in regressive or progressive alterations in states of consciousness. Such a model would also provide a tool for sharpening distinctions between qualities of thought form and qualities of thought organization. The frequent blur of this distinction arises because of the need in the psychoanalytic situation to focus on thought content and control rather than on thought form. Thus, there is a tendency to equate quali-

Sculpting the Family

Abstract: In family sculpting the members of a family create a physical representation of their relationships at one point in time by arranging their bodies in space. The techniques, rationale, and uses of this method no described.

REPRESENTATION OF FUNCTIONS BY SERIES AND CLASSES ϕ(L)

Abstract: In the paper we give a survey of results concerning the problems of representing functions by series in various systems, and of the uniqueness of such a representation. The account covers older results as well as those of recent years due to several authors. Much attention is also paid to questions of the validity of the Weierstrass theorem and of representing functions in the classes (L).

Method for providing representation for needed work force in a store

Abstract: Method of providing representation for needed work force in a store by determining the arrival rate of customers at a store; determining the rate of customers actually checking out, determining the average duration for customer check out; and providing a representation of number of clerks needed on basis of the determinations made under the previous steps and further on basis of an arbitrarily selected average waiting period per customer.

Method of making composite three dimensional picture

Abstract: A composite pictorial representation having a three dimensional effect as well as the method of making the same, which comprises a relatively deep frame structure adapted to receive and enclose a relatively thick composite picture that is made from a number of copies of a photograph or the like having background, middle ground and foreground subject matter therein, and wherein certain copies of the photograph are cut or trimmed so that only the middle ground and foreground subject matter remain, and the middle ground and foreground portions are attached in overlying spaced relation to a whole copy having the background thereon. The resulting composite pictorial representation has the background, middle ground and foregound portions of the photograph appearing in successively forwardly spaced relation to provide a visual three dimensional effect.

Alternative puzzle system

Abstract: A puzzle comprising a plurality of pieces which can be assembled in more than one configuration, either as a three dimensional, recognizable shape or as a two dimensional surface which presents a graphic representation.

Error detecting translator

Abstract: A signal translation circuit arrangement comprises two translators that operate according to different rules of action. The translators respond to each valid input signal representation by forming identical corresponding output signal representations and the translators respond to each invalid input signal representation by forming nonidentical output signal representations. Invalid input signal representations and circuit malfunctions are detected by comparing the output signals generated by the translators.
