Many studies have argued for distinct but complementary contributions from each hemisphere in the control of movements to visual targets. Investigators have attempted to extend observations from patients with unilateral left- and right-hemisphere damage, to those using neurologically-intact participants, by assuming that each hand has privileged access to the contralateral hemisphere. Previous attempts to illustrate right hemispheric contributions to the control of aiming have focussed on increasing the spatial demands of an aiming task, to attenuate the typical right hand advantages, (...) to try to enhance a left hand reaction time advantage in right-handed participants. These early attempts have not been successful. The present study circumnavigates some of the theoretical and methodological difficulties of some of the earlier experiments, by using three different tasks linked directly to specialized functions of the right hemisphere: bisecting, the gap effect, and visuospatial localization. None of these tasks were effective in reducing the magnitude of left hand reaction time advantages in right handers. Results are discussed in terms of alternatives to right hemispheric functional explanations of the effect, the one-dimensional nature of our target arrays, power and precision given the size of the left hand RT effect, and the utility of examining the proportions of participants who show these effects, rather than exclusive reliance on measures of central tendency and their associated null hypothesis significance tests.

Certain palaeontological observations, of which some examples are described do not fit in either a Lamarckian or Darwinian view of evolution. Both of these mechanistic theories assume small character-changes in the end stages of ontogeny, which gradually accumulate and are supposed thus to have given rise to all evolutionary progress. Palaeontology, on the other hand, teaches that the fundamental qualitative changes in the morphological plan have taken place in a saltatory manner in more or less young ontogenetic stages . Only (...) after the morphological plan has been built in a phylogenetic phase of explosive, early ontogenetic changing of type follows a phase of stable, continous evolution. It is shown that, theoretically, no other kind of fundamental change in the organisation is possible and that many, otherwise inexplicable, phenomena, the lack of transition forms, the question of ancestral stocks, the ideas of the biology of organisms as a “whole” etc., find their explanation by this means.Il y a certaines observations paléontologiques, dont l'auteur donne plusieurs exemples, et qu'on ne pourrait mettre d'accord avec un aspect larmarckienne ou darwinienne. Ce sont là des essais mécaniques d'explication, qui comptent avec de petites modifications de caractères dans les derniers stades de l'ontogénèse qui se totalisent peu à peu et devraient ainsi avoir occasionné tout progrès phylogénétique. Par contre, la paléontologie enseigne que les transformations qualitatives profondes des plans de constructions ont évolué par bonds dans les stades ontogénétiques plus ou moins juvéniles . C'est seulement après que les types ont été formés dans une phase phylogénétique de transformation explosive et juvénile, qu'une phase d'une évolution stable et continue vient s'y ajouter. On démontre que théoriquement un autre procédé d'un changement profond d'organisation est absolument impossible et que de cette manière un grand nombre de phénomènes par ailleurs incompréhensibles trouvent de la sorte leurs explications: par exemple l'absence des formes transitoires, la question des formes de racines, les conceptions de la biologie du „tout” de l'organisme etc. (shrink)

L’article est une prise de position critique à propos du livre de Habermas Faktizität und Geltung . Plus précisément, il s’agit d’une critique de l’ « architectonique” de la différenciation discussionnelle, menée à propos du rapport entre principe de discussion, principe moral, principe du droit et principe démocratique. Mon point de vue résulte de la position de l’éthique de la discussion comme discipline de base de la philosophie pratique, dans la perspective d’une fondation pragmatique-transcendantale ultime. Une « architectonique » alternative (...) de la différenciation discussionnelle du point de vue de l’éthique de la discussion est proposée.The following essay takes a critical stand to Habermas’ book Faktizität und Geltung of 1992 ; more precisely expressed : my stance is critical with regard to Habermas’ new « architectonics » of discourse-differentiation concerning the relationship between « discourse-principle », « principle of morality », « principle of law », and « principle of democracy ». My critique represents the view of a « transcendentalpragmatic ultimate foundation of discourse-ethics » . An alternative « architectonics » of discourse differentiation in the sense of discourse-ethics is suggested. (shrink)

El resurgimiento de la educación tradicional en los Estados Unidos ha generado un intenso debate en la esfera pública. Este artículo examina el debate discursivo que rodea este fenómeno. A medida que las críticas hacia los enfoques educativos progresistas se intensifican, defensores de la educación tradicional argumentan a favor de un retorno a métodos pedagógicos más tradicionales. Este resumen destaca el papel de la esfera pública como espacio de conflicto y negociación de ideas en torno a la educación. Al explorar (...) las perspectivas y los argumentos en disputa, el artículo busca arrojar luz sobre el resurgimiento de la educación tradicional y su impacto en el sistema educativo de los Estados Unidos.

Anknupfend an die platonische Begriffsbildung der "Kalokagathie" ("Schongute") wird seit dem 19. Jahrhundert diskutiert, inwieweit asthetischen Kategorien Aussagekraft auch fur Politik und Staat zukommt.

The cellular capacity to internalise objects, involving attachment, engulfment and uptake, exists in virtually all organisms. Many uptake reactions are associated with cell signalling. However, the mechanical forces that form endocytotic vesicles are not known. We propose a ‘leverage‐mediated’ uptake mechanism involving lateral cross‐linking processes on the cell surface that can generate the configurational energy to create an inverse curvature of the membrane.

Morphogenetische Untersuchungen ermöglichen eine zuverlässige Ermittlung der homologen Elemente in der Lobenlinie der Ammonoidea. Umgekehrt lehrt eine Analyse hypothetischer Vorstellungen, die man sich über die phylogenetischen Zusammenhänge gewisser Ammoneen-Gruppen gebildet hatte, daß sich daraus die Homologie-Beziehungen nicht herleiten lassen. Es besteht keine Konkordanz zwischen den morphologischen Tatbeständen und den stammesgeschichtlichen Konstruktionen, die sich in diesen Fällen als falsch erweisen. Daraus wird der Schluß gezogen, daß der Homologie-Begriff nur unvoreingenommen morphologisch definiert und interpretiert werden kann. Die auf morphologischer Grundlage ermittelten Homologien (...) entscheiden über die Möglichkeit stammesgeschichtlicher Verknüpfungen, nicht aber umgekehrt phylogenetische Deutungen über die Homologie. Ebenso kann die stets unsichere Phylogenie nicht zur Grundlage der Systematik gemacht werden. Auch da liegen die logisch-methodischen Zusammenhänge umgekehrt: Die im System ausgedrückte Formverwandtschaft ist die Basis der Phylogenie und nicht die Phylogenie die der Morphologie. Die Theorie eines Phylogenetischen Systems der Organismen wird abgelehnt.Morphogenetic investigations provide a firm basis for an exact identification of homologous elements in the suture line of ammonoids. On the other hand an analysis of current phylogenetic connections of certain ammonoid groups demonstrates that they give no clue for tracing homologies. There is no agreement between the morphological facts and the phylogenetic fictions, the latter in these cases being definitely wrong. Therefrom it is concluded that the concept of homology can only be defined and interpreted on a morphological basis. The established homologies are decisive for the admissibility of phylogenetic connections and not phylogenetic inferences for the recognition of homologies. In the same manner systematics cannot be based on the always unsafe phylogeny, but only on the actual facts of morphology. The concept of a phylogenetic classification of organisms is rejected.

Insect endoparasitoids are able to circumvent the defense reactions of their habitual hosts. In a hymenopteran wasp species, virus‐like particles, found on the egg surface are responsible for the protection against the encapsulation reaction of the host caterpillar. Some of the particle proteins are structurally and probably functionally related to host protein(s). Biological properties of some of the host proteins suggest that they might be involved in the insect defense reaction.

Recent studies suggest that insects use pattern recognition molecules to distinguish prokaryotic pathogens and fungi from “self” structures. Less understood is how the innate immune system of insects recognizes endoparasitic Hymenoptera and other eukaryotic invaders as foreign. Here we discuss candidate recognition factors and the strategies used by parasitoids to overcome host defense responses. We suggest that host–parasitoid systems are important experimental models for studying how the innate immune system of insects recognizes foreign invaders that are phylogenetically more closely related (...) to their hosts. The strategies used by parasitoids suggest that insects may employ “hidden-self” recognition molecules for attacking foreign objects intruding the open circulatory system.
