Fornix problem: Why do lesions of the fornix, which connects the hippocampus (HF) to the medial mammillary nucleus (MMN), often cause no deficits in tasks severely affected by lesions of HF or MMN? Solution: The direct HF feedback to antero ventral (AV) thalamus (MMN [Rightarrow A: implies] AV [Leftrightarrow A: l&r dbl arrow] HF), which is blocked by MMN lesions but not fornix lesions, is sufficient for nonscene-relevant consolidation.

I agree with Revonsuo that dreaming, particularly about risky scenes, has a great selective advantage. Although the paleoamygdala system generally facilitates stress and alarm, the system which inhibits stress and alarm, initiates bold actions, and mediates learning in risky scenes is the arche, hippocampal system (Papez circuit). Because all thalamic nuclei are inhibited during sleep except arche, Papez probably also dreams in risky scenes. [Revonsuo].

L'art, loin des habitudes qui figent tout réel élan créateur, est la jeunesse du monde. Il a tout à créer. Tout à construire, tout à proposer. Les temps de l'art mimétique comme ceux de l'art visionnaire sont révolus, pour laisser place à ceux de l'intuition. Cet ouvrage revendique ainsi la liberté de s'imposer des règles, de nouvelles règles et préconise un art de l'intuition, un art de la sensibilité, qui puisse s'exprimer avec spontanéité, une spontanéité qu'il n'est possible d'obtenir qu'après (...) un long travail. L'art ne doit plus être pensé comme une intention. Suivant ce principe, le scénario dans le récit doit être abandonné. Du point de vue de la forme, la poésie doit pouvoir mélanger dans le même poème vers libres. vers en prose, versets et alexandrins, selon le souhait du poète. De même, il faut oser une autre forme de peinture, qui ne soit ni figurative, ni abstraite, mais intuitive, née du flou ou de l'éblouissement, de la fulgurance intuitive! Franchir les frontières, à commencer par celles de l'intolérance, en faisant dialoguer et se croiser différentes disciplines artistiques, pour aller vers un espace pluriartistique, ouvre ainsi de nouvelles perspectives de création."--Page 4 of cover.

This article examines the impact of the reading assessment, DIBELS (Dynamic Indicators of Basic Early Literacy Skills), on literacy education through the Habermasian lens. It argues that DIBELS, along with other systemic forces, has surged beyond its domain as a mere assessment and colonized the lifeworld of literacy education by distorting the meaning of the teaching and learning of literacy.This article calls for a critical reflection on the systemized practices in literacy education and for a return to a lifeworld where (...) literacy is considered more than a testable skill.

Some recent trends of modern biology, which seem to have a most consequential influence to the further treatment of the problem of the origin and evolution of flowering plants, are shortly reviewed in this article.Several new discoveries and observations about pollinating insects revealed to some extent the mystery of the evolution of flower types. The deciphering of the definite signs and codes of communication among social insects and the interpretation of a well developed sign language of bees belong to the (...) most remarkable achievements of modern biology indeed. Besides its revolutionary impulse in the field of animal behavior these discoveries helped to solve several problems in the evolution of flowering plants.An attempt is made in this article to classify the existing main flower types according to their evolutionary tendency from primitive → simple → radiate → protected → zygomorphic flowers In this assortment of flower types is reflected the historical development of flowering plants since their early beginning in Cretaceous period till their domination in the recent world vegetation .In this evolution of flower types is mirrored further the progressive evolvement of numerous senses of the pollinating insects. The pollinators of the Middle Mesozoicum were surrounded by primitive flower types and could distinguish but some primitive colors like white, yellow and green.Two different methods of classification of flowering plants are used in this study. A typological assortment of flowers according to their ecological characteristics is co-ordinated with the taxonomic classification of phylogenetic groups . The evolution of angiosperms can be studied more successfully, if both the typological and taxonomic trends of this groups are analyzed.Quelques nouvelles découvertes et essais sur la dissémination du pollen par les insectes sont discutés du point de vue de l'évolution des types de fleur. L'activité sélective et la stabilité de ces insectes se trouvent être des facteurs les plus conséquents dans l'évolution des types de fleurs.Deux méthodes différentes de classification des plantes angiospermes sont employées dans cette étude. Un assortiment typologique de fleurs suivant leurs caractéristiques écologiques est coordiné avec la classification systématique des groupes phylogénétiques . L'évolution des angiospermes peut être étudiée avec plus de succès si les méthodes typologiques et systématiqes sont appliquées.Es werden in diesem Aufsatz einige neue Versuchsergebnisse über die wechselseitigen Beziehungen zwischen den pollenübertragenden Insekten und der Entwicklungsgeschichte der Blütentypen näher erörtert.Es sind unter diesen Umständen zwei verschiedene Arbeitsverfahren für die Klassifikation der Blütenpflanzen angewandt worden. Eine typologische Einteilung nach den ökologischen Merkmalen und eine systematische Schilderung nach den phylogenetischen Gruppen . Die Anwendung von diesen beiden Methoden gestattet uns eine bessere Übersicht über die Entwicklungsgeschichte der Blütenpflanzen. (shrink)

The representation of public and private partnership in higher education management as a mechanism of forming the added value of human capital is specified. An algorithm of economic effect calculation of universities and entrepreneurs cooperation at training undergraduates is given. As shown in the article the economic effect is achieved by developing wide cooperation with entrepreneurs in public and private partnership and widening the undergraduates’ flow at conducting practices and independent work in individual education.

A survey of 106 medical students assessing their interest in and attitudes to medical ethics in the curriculum is reported by the authors. Results indicate that 64 per cent of the students rated the importance of medical ethics to good medical care as high or critical and 66 per cent desired to learn more about the topic. However, in reports of patient encounters identifying ethical issues, less than six per cent of the students reported a frequency of more than one (...) such patient encounter per week. The students also demonstrated a greater awareness of more obvious ethical issues than of more subtle, less publicised issues. When asked how medical ethics should be taught, the students clearly affirmed a desire for an integrated exposure to the subject throughout the medical curriculum. Possible implications of these findings for medical education are discussed. (shrink)

Originally published in 1933, this book was written to provide the younger reader with a guide to the basic elements of economics, preparing them with the tools to earn a living and spend money in a responsible fashion. The text was based on a series of lessons 'given to pupils of ordinary ability during their last two terms in a reorganized senior school'. Illustrative figures are included. This book will be of value to anyone with an interest in economics and (...) the history of education. (shrink)
