    Notes: In an article, published by Kyklos 1965, K. W. Rothschild undertakes to introduce sociological factors into Kaldor's theory of distribution, therewith following a German tradition. In a long-run variant both saving ratios of capitalists and workers are supposed to be influenced by the level of the wages sum. Income distribution is thus explicitely depending upon wages policy.This article accepts the introduction of functionally dependent savings ratios and the consideration of wages policy as useful. The functions actually used by Rothschild however, are criticized for formal and expecially economic reasons: (a) the functions are empirically highly questionable; (b) there is no differentiation between payed-out and retained profits, i. e. the savings-ratio out of profits is without content; (c) the behaviour of groups is deduced from a picture of social structure no longer relevant. As the decisive relations do not stand critical examination, this attempt to introduce sociological factors into the theory of income distribution must therefore be considered a failure.

    Description / Table of Contents: Zusammenfassung 3 Experimente wurden durchgeführt, in denen die Versuchspersonen (39 Studenten) aufgefordert wurden, die ihnen am „angenehmsten“ erscheinende Entfernung zu verschiedenen Reizobjekten zu wählen. Es zeigte sich, daß die Versuchspersonen näher an Personen als an Fotografien von Personen oder Gegenständen herangingen. Männliche Versuchspersonen gingen näher an weibliche als an männliche Reizpersonen heran. Es bestand außerdem die Tendenz einer größeren Annäherung an Personen, wenn diese die Versuchsperson anblickten. Die „angenehmste“ Entfernung war individuell verschieden und über mehrere Wochen stabil. Sie war außerdem vom räumlichen Bezugssystem abhängig; in diesem Zusammenhang konnte die Ausbildung von Einstellungen gezeigt werden. Die Ergebnisse wurden im Hinblick auf ein Gleichgewichtsmodell sozialer Kräfte von Argyle u. Dean diskutiert.
    Notes: Summary Three experiments were conducted in which subjects (39 students) were to choose the distance from various stimulus objects which appeared “most comfortable” to them. It was shown that subjects approached actual persons more closely than they did photographs of persons or objects. Male subjects approached female stimulus objects more closely than they did males. There was a tendency of greater approach if the stimulus persons gazed at the subjects. The “most comfortable” distance was specific for the individual and remained stable over a period of several weeks. It also depended upon the spatial frame of reference; in this connection the development of sets could be shown. The results were discussed in relation to a model for the equilibrium of social forces from Argyle and Dean.

    Description / Table of Contents: Zusammenfassung 1. Die normale Entwicklung der Meduse vonPodocoryne carnea M.Sars wird aufgrund morphologischer und anatomischer Kriterien in insgesamt 10 Differenzierungsstadien unterteilt. 2. Medusenknospen, die frühzeitig vom Blastostyl isoliert werden, sind lebensfähig und vollbringen verschiedene Entwicklungsleistungen, deren Art und Häufigkeit vom Entwicklungsalter der Knospe im Moment der Isolation abhängig sind. 3. Junge Medusenknospen der Stadien 1–4 sind nach Isolation einem Dedifferenzierungsprozeß unterworfen, der zu einem sog. „Kugelstadium“ führt. Aus diesem morphogenetisch indifferenten Stadium können Stolonen und aus diesen wiederum Nährpolypen entstehen. Dieser von jungen Medusenknospen ausgehende Strukturwandel kann als Metaplasie bezeichnet werden. 4. Ältere, in den Stadien 5–8 isolierte Medusenknospen entwickeln sich in der Regel zu Medusen oder medusenähnlichen Gebilden weiter. Der kritische Zeitpunkt, in welchem die Entwicklungsrichtung der Meduse irreversibel festgelegt wird und von dem aus die Differenzierung der Meduse autonom erfolgen kann, liegt zwischen den Entwicklungsstadien 4 und 5. 5. Zellreaggregate, die durch Dissoziation voll ausdifferenzierter Medusen gewonnen wurden, bildeten in wenigen Fällen Stolonen und stolonenähnliche Gebilde. Dies bedeutet, daß wenigstens ein Teil der die Meduse aufbauenden Zellen die Fähigkeit zur funktionellen und strukturellen Metaplasie nicht irreversibel verloren hat. 6. Sämtliche im Verlaufe dieser Untersuchungen beobachteten Strukturwandlungen führten über den als niedrigste Realisationsstufe zu bezeichnenden Zustand des Stolo, aus dem unter günstigen Voraussetzungen die nächsthöheren Stufen (Freßpolypen, Blastostyle) hervorgehen können.
    Notes: Summary 1. The normal development of medusa ofPodocoryne carnea M.Sars is divided into 10 different stages according to morphological and anatomical criteria. 2. Medusa buds are viable and develop different patterns of differentiation when isolated early from the blastostyl. These patterns depend on type and frequency of the bud's age of development at the moment of isolation. 3. After isolation young medusa buds of the stages 1–4 are submitted to a process of dedifferentiation leading to a „Kugelstadium“ (two-layered sphere). Out of this morphogenetically indifferent stage stolos can emerge. These often give rise to gasterozooids. This structural change, originating from young medusa buds, may be termed metaplasia. 4. Older medusa buds isolated in the stages 5–8 develop normally into medusae or medusa-like structures. The critical phase when the direction of development of the medusa is irreversibly fixed and out of which the differentiation of the medusa can autonomically emerge, lies between the bud-stages 4 and 5. 5. Aggregates of cells, obtained by dissociation of fully differenciated medusae, in a few cases produced stolos and structures of stolo-like shape. This means that at least part of the medusa cells has not irreversibly lost the ability to functional and structural metaplasia. 6. All the changes of structure, observed in the course of the investigations, led to a stolo to be designated as the most primitive stage of differentiation. Under favourable conditions the next higher stages (gasterozooids, blastostyls) can emerge.

    Notes: Abstract The domain structure of nickel single crystals of prismatic form and with a simple “two phase” basic structure has been investigated by using the magnetooptical Kerr technique. Observations of the periodical basic structure and of the closure domains on the side faces and their dependence on temperature are reported for the idealized and hysteresis curve. The results are compared with those of domain theory. Some discrepancies in the temperature dependence in weak fields and the interpretation of the Kerr pattern we believe to decrease if the model for the closure domains will be modified, especially by using an echelon structure and by modifying the stray fields.

    Notes: Resumen El volumen de la masa roja circulante descendió en un 24% en ratas radioyodotiroidectomizadas después de 8 meses de administrado et I131. Hubo un descenso similar en la sintesis diaria de hemoglobina/100 g de peso corporal. Los estudios de la cinética del hierro fueron semejantes en ambos grupos. No hubo aumento de la eritropoyesis inefectiva ni del periodo intermitótico medular. El número de células eritroides en la médula ósea de las ratas atiroideas mostró una disminución significativa con respecto a los animales controles, hecho que seria el responsable de la anemia post-tiroidectomia.

    Notes: Summary The variations of glycogen, lipids and ashes in muscular tissue of the Rainbow trout (Salmo gairdnerii Rich.) show that during sexual cycle there are 4 periods. Each period corresponds to a particular biological activity. The sexual activity cannot explain all the modifications of glycogen content.

    Notes: Summary Crystals of carotene in plant cells (carrot root, corona ofNarcissus etc.) have been attributed to the orthorhombic or the hexagonal system. However, an optical investigation showed that they have a lower symmetry. In the case of the crystals in the corona ofNarcissus, the structural identity with syntheticβ-carotene is proved by X-ray and electron diffraction analysis. Although the geometry of the electron diffraction patterns is almost indistinguishable from hexagonal, its reflections can be identified with those from the planes of the monoclinic lattice ofβ-carotene. The face of the plate-shaped crystals corresponds to (102).
