The field of surface polariton physics really took off with the prism coupling techniques developed by Kretschmann and Raether, and by Otto. This article reports on the construction and operation of a rotatable, in vacuo, variable temperature, Otto coupler with a coupling gap that can be varied by remote control. The specific design attributes of the system offer additional advantages to those of standard Otto systems of (i) temperature variation (ambient to 85 K), and (ii) the use of a valuable, additional reference point, namely the gap-independent reflectance at the Brewster angle at any given, fixed temperature. The instrument is placed firmly in a historical context of developments in the field. The efficacy of the coupler is demonstrated by sample attenuated total reflectance results on films of platinum, niobium, and yttrium barium copper oxide and on aluminum/gallium arsenide (Al/GaAs) Schottky diode structures.

Management sciences and corporate practices of companies bring extensive views on the ethics and the corporate responsibility. The practical experiments try to build, and to make appropriate themselves to itself by the actors of companies, the deontological ethics governed by principles. Dialogue and deliberation are the political frame given to this construction. A question seems then central, that of the ultimate rational foundation of the morality and its normative contents. K.O. Apel’s propositions concerning his ethics of the discussion founded in a pragmatico-transcendental way seems to me to allow an essential advance on the subject. According to Apel, this foundation should supply: 1) The bases of an ultimate rational foundation of the morality and its normative contents, 2) The bases of the universal validity of a principle of justice, solidarity and co responsibility, 3) The bases of an ethics of the responsibility, but not an deontological ethics, governed by principles which could come to complete and to legitimize socio organizational processes and systems of relations which, placed in a new ethical context, could continue. In this article, I try to show in what K.O. Apel’s propositions allow to enrich a reflection opened by the research works in business ethics and in organizational behavior.

Se transcribe la conferencia titulada Tendencias y problemas de la Enseñanza de nivel medio en la Europa de hoy, pronunciada en la Reunión del Profesorado de Granada por el Profesor Otto Ángel, en abril de 1968. Se habla en primer lugar del espíritu de unión europeo y de las figuras que lo han impulsado, como Adenauer, De Gasperi y Schumann. Posteriormente se adentra en la cuestión de la educación secundaria en Europa. Se destaca como del 20 al 28 de abril de 1967 se celebró en Málaga, una Semana de estudios, organizada por el Gobierno español bajo los auspicios del Consejo de Europa cuyo tema fue La actitud humanista en la enseñanza secundaria para la Europa del mañana. Se precisó como el humanismo no se reduce a las llamadas humanidades de los tiempos pasados, es decir al estudio de las lenguas y literaturas griega y latina, sino que todas las asignaturas tienen un núcleo humanístico. Pero el núcleo central lo integran los siguientes temas: las organizaciones europeas de cooperación pedagógica, las cuestiones de orientación escolar concernientes a la enseñanza secundaria y los métodos de enseñanza contrapuestos. Para terminar se señala que otro tipo de actividad pedagógica moderna lo constituye la llamada forma social-integradora, en la que el profesor da una visión general del trabajo proyectado. Este proyecto es sometido a discusión y a decisión por grupos de alumnos estimulados por el profesor.

This essay traces the development of Otto Neurath’s ideas that led to the publication of one of the first series of children’s books produced by the Isotype Institute in the late 1940s, the Visual History of Mankind. Described in its publicity material as ‘new in content’ and ‘new in method’, it embodied much of Otto Neurath’s thinking about visual education, and also coincided with other educational ideas in the UK in the 1930s and 1940s. It exemplified the Isotype Institute’s approach: teamwork, thinking about the needs of younger readers, clear explanation, and accessible content. Further, drawing on correspondence, notes and drawings from the Otto and Marie Neurath Isotype Collection at the University of Reading, the essay presents insights to the making of the books and the people involved, the costs of production and the influence of this on design decisions, and how the books were received by teachers and children.
