TL;DR: In this paper, the authors measured the cloud point curves (CPC) for 1-4 cis polybutadiene (M r = 40,000-830,000) in n-hexane, 2-methylhexane and 2,2,3 trimethylbutane.

TL;DR: In this article, a comparison is drawn between unprogrammed reinforcement practices in a ward with token economy and in a control ward, showing that the aides of the token economy ward reinforce appropriate behaviors more than do those on the control ward.

TL;DR: An approach to self-organizing systems based upon information theory is presented and it is shown that the capacity of an information source is given by the logarithm of its inverse entropy rather than by its negative entropy.
Abstract: This paper is the continuation of a preceding one which appeared in this journal, and presented an approach to self-organizing systems based upon information theory. To begin with, some illustrating examples try to show why one can think that the concept of information should play a crucial role in a theory of general systems. Then the concept of ‘ structural entropy ’, and the ‘ evolution principle ’ that we have previously introduced, are improved here in a definitive form. The concept of ‘ information potential ’ is defined and we show that the capacity of an information source is given by the logarithm of its inverse entropy rather than by its negative entropy. Composition laws for the structural entropy are stated and it is shown that these concepts provide an approach to information balance. Some simple examples are outlined to connect this approach with well known existing results.

TL;DR: A new approach to determine S's handedness from hand-efficiency tests, instead of hand-preference questionnaires, is presented here and a formula to isolate ambidextrous individuals is proposed.

TL;DR: In this article, a linear programming model for educational planning, by allowing for choice among techniques of production, permits the introduction of non-constant factor substitution into the production function.
Abstract: This linear programming model for educational planning, by allowing for choice among techniques of production, permits the introduction of non-constant factor substitution into the production function. The model is applied to educational planning in France and treats simultaneously four kinds of educated manpower and capital in the seven major industrial sectors of an economy. Alternative techniques are drawn from seven other countries for which reasonably comparable data are available. These techniques of production define the production function and determine the demand for educated manpower and capital independently of the supply of these factors. An initial static model maximizes GNP (holding its composition constant) subject to a fixed supply of manpower and capital. The model thus tests whether supply is the constraining factor in the choice of technique in theshort run. In the case tested, it is. In the dynamic version of the model, supply is allowed to increase by means of education (for manpower) and investment (for physical capital). Consumable GNP, that is GNP net of the cost of education and investment, is maximized. Terminal capital stock problems make it impossible to test the model directly. The problem is then broken down into two steps: the identification of the techniques (one for each industry) which permit the greatest net contribution to GNP, and the movement in time towards these "optimal" techniques. The first of these steps is solved using a dual version of the model, but the second is not attempted in this paper.

TL;DR: In this article, the authors propose an interpretation classique du concept d'ideologie orienting cette problematique vers l'aspect de determination sociale des idees telle la sociologie de la connaissance which l'identifie a des problemes de fausse conscience, d'illusions, de justifications, etc.
Abstract: Meme si le concept d'ideologie remonte dans ses premiers emplois a Destutt de Tracy, il est sans contredit un concept pour lequel le marxisme reclame un privilege. C'est a Karl Marx que l'on reconnait le role d'instigateur de cette problematique. L'interpretation classique du concept d'ideologie oriente cette problematique vers l'aspect de determination sociale des idees telle la sociologie de la connaissance qui l'identifie a des problemes de fausse conscience, d'illusions, de justifications, etc. Que l'on se refere a Lukacs, a Mannheim et encore recemment a Althusser, le probleme de l'ideologie se pose en termes de conscience, de representation determinee par des conditions socio-economiques.

TL;DR: The conflits between l'Union Sovietique et les nouveaux Etats socialistes as mentioned in this paper have been a source of concern for l'U.S. since the second guerre mondiale.
Abstract: Depuis l'emergence du socialisme (du type leniniste) hors des frontieres d'un seul pays et la formation du camp socialiste e la fin de la seconde guerre mondiale, c'est-a-dire, depuis un peu plus de 25 ans seulement, de nombreux conflits ont surgi dans les relations entre l'Union Sovietique et les nouveaux Etats socialistes. Sur les 13 Etats socialistes qui existent actuellement dans le monde, outre l'urss, 8 d'entre eux, c'est-a-dire, la majorite, ont eu des conflits plus ou moins aigus selon les cas, dans leurs relations avec celleci. Ce fut d'abord, le conflit sovieto-yougo-slave de 1948, puis les crises de Pologne et de Hongrie en 1956, les conflits avec l'Albanie et la Chine qui ont commence, ouvertement en 1960 et qui durent toujours, le conflit avec la Roumanie qui a commence en 1962 au sujet de l'integration economique de l'Europe de l'Est, qui a change de forme par la suite et qui n'est peut-etre pas encore termine, le conflit avec Cuba sur la strategie revolutionnaire en Amerique latine, qu'on peut situer de 1965 a 1968, et enfin, la crise de Tchecoslovaquie de 1968. Les moins aigus de ces conflits sont ceux qui sont survenus dans les relations de l'urss avec la Roumanie et avec Cuba.
