The sociodynamogram--a contribution to the objectivization of group process

Two simple sociometric techniques for practical use are described which are derived from the data given in the sociogram. Compared with the conventional sociogram, the group rank score we use everyday therapy has the advantage that it can be published. It permits members of the group to better identify the social situations which cause specific psychic impulses. The sociogram is reserved for the therapist. In our opinion the sociodynamogram has certain advantages over both methods because it provides an insight into spheres which are inaccessible in the sociogram and group rank score.     

Quantitative amino acid determination in the serum and cerebrospinal fluid in endogenous depressions

The levels of 20 amino acids were measured in the plasma and cerbrospinal fluid of 41 patients with endogenic depressions. The plasma levels of 12 amino acids were found to be significantly lower in the patients than in the control group, but cerebrospinal fluid levels were significantly lower only in the case of taurine, glutamine, phenylalanine and aginine. Comparison of the same amino acid levels in treated and non-treated patients showed that serine and alpha-aminobutyric acid serum concentrations were higher in the nontreated patients. The tyrosine and phenylalanine levels in the cerebrospinal fluid of the patients who had received medicamentous treatment were higher than in the other group.     

Object relations and multiple personality: an exploration of the literature

Multiple personality is a dissociative hysterical condition in which there are two or more autonomous personalities. Historically multiple personality has been viewed as an oedipal conflict. Case studies, however, indicate the importance of preoedipal dynamic issues as well. Both ego splitting and oedipal repression seem to be the basic defense mechanisms. The depressive position, in which there is integration of good and bad objects, has not been reached. Objects are split on the basis of sex in that the mother is seen as all bad, while the father is seen as all good. Multiple personality can be considered to occupy a position between oedipal and preoedipal development.     

On the logic of adverbs

In the paper I investigate aspects of adverbial modification as an operation applying an adverb or adverbial phrase to a predicate and thereby creating a new predicate. The logic of adverbial modification, on this view, belongs to the logic of predicate modifiers. The theory I present is intended to cover not only adverbial modification but also attributive modification, but problems concerning the latter will not be given any special attention.     

Nondeterministic three-valued logic: Isotonic and guarded truth-functions

Nondeterministic programs occurring in recently developed programming languages define nondeterminate partial functions. Formulas (Boolean expressions) of such nondeterministic languages are interpreted by a nonempty subset of {T (“true”), F (“false”), U (“undefined)}. As a semantic basis for the propositional part of a corresponding nondeterministic three-valued logic we study the notion of a truth-function over {T, F, U} which is computable by a nondeterministic evaluation procedure. The main result is that these truth-functions are precisely the functions satisfying four basic properties, called \( \subseteq \) -isotonic, \( \subseteq \) ^?-isotonic, hereditarily guarded, and hereditarily guard-using, and that a function satisfies these properties iff it is explicitly definable (in a certain normal form) from “if..then..else..fi”, binary choice, and constants.     

Tests for stability in linear structural equation systems

Interpretations regarding the effects of exogenous and endogenous variables on endogenous variables in linear structural equation systems depend upon the convergence of a matrix power series. Convergence depends upon the eigenvalues of the structural coefficient matrix. The test for convergence developed by Jöreskog and Sörbom is shown to be only sufficient, not necessary and sufficient.
