    Notes: In order to strengthen research coordination and increase the effectiveness of investments, the Swiss Centre for International Agriculture (ZIL) embarked on a formal priority-setting exercise. The paper documents the decision-making process, examines the application of the analytic hierarchy process (AHP) as decision-support tool, and discusses the outcome of the process. Starting with a set of alternative research areas and potential decision criteria, the process went through several steps where necessary information was gathered and processed, criteria structured and weighted, and alternative research areas assessed against criteria. The AHP helped structure the multi-criteria decision problem, elicit criteria weights, and evaluate the expected contributions of the alternatives to the previously defined objectives. The outcome of the process was a prioritized list of potential research areas for ZIL's next programme phase. Sensitivity analysis was performed to test the stability of the priority ranking. The paper concludes with a discussion on the group decision-making process and an outlook onto the next steps towards a better focused research agenda of ZIL.

    TOWARD A THEORY OF COMPILATION FOR NATURAL LANGUAGE GENERATION (1992)

    Notes: This article proposes a framework in which knowledge compilation can be exploited in a principled manner for the task of generating natural language. We have constructed an utterance generator for one side of a realistic dialogue that exploits compiled knowledge of, for instance, the effects of discourse pragmatics on text plans, and the effects of register, style, and politeness on text realization. The motivation for this work is the significant impact that compiled knowledge has on the speed of language generation.

    Description / Table of Contents: Résumé Un caractère de l'agroforesterie est l'intégration d'espèces indigènes dans des systèmes appropriés d'utilisation des terres. Quelques essences locales (arbres et arbustes) sont particulièrement appréciées pour leur valeur nutritionelle. Le Ferlo, caractérisé par une végétation de type Savane arbustive, est la région la plus aride du Sénégal. La population locale utilise pour son alimentation beaucoup de plantes locales. On peut citer les plus importantes: Adansonia digitata, Balanites aegyptiaca, Ziziphus mauritiana, Boscia senegalensis et Cassia obtusifolia. Une vingtaine d'espèces environ sont consommées à une quantité plus faible. Les plantes présentent comme principale fonction la fourniture de Vitamine A, B2 et C qui font défaut pendant les périodes de disette. A peu prés 50% des espèces qui poussent au Ferlo sont consommable, mais seulement les plus connues sont consommées. Une exploitation ultérieure de ces ressources naturelles et leur intégration réfléchie dans des systèmes agroforestiers est recommendable au point de vue économique et écologique.
    Notes: Abstract One aspect of agroforestry is the integration of indigenous species into appropriate land use systems. Some local trees and shrubs are particularly appreciated because of their value in human nutrition. The Ferlo is the most arid part of Senegal, covered by open woodland. The local population is using several indigenous plants for food. Most important are Adansonia digitata, Balanites aegyptiaca and Ziziphus mauritiana, as well as Boscia senegalensis and Cassia obtusifolia. Some 20 more species are consumed to a smaller extent. Their main function is to supply the vitamins A, B2 and C, for which seasonal shortages occur. About 50% of all plants growing in the Ferlo have edible parts, but only the most common ones are consumed. Further exploitation of these natural resources and their conscious integration into agroforestry systems is economically and ecologically recommendable.

    Notes: Abstract The Southwest Regional Laboratory, through major funding from the National Science Foundation (ESI-9450235), has developed a series of eight instructional modules for use in common secondary school physical science that address three central goals of U.S. science literacy education: (1) to motivate students who have previously shown little interest in science; (2) to accomplish deep change in students' internalized conceptions of the structure and workings of the physical world; and (3) to build greater understanding, in both teachers and students, of the process and culture of scientific activity. Beginning with a discussion of the conceptual scaffolding that undergirds the project's pedagogical approach, the paper presents an overview of MindWorks' goals, the materials that have been developed to achieve these goals, and the progress of the pilot implementation and project evaluation.

Die Verbindung kristallisiert in dunkelblauen orthorhombischen Plättchen mit a = 17,779(4), b = 45,363(9), c = 9,096(2) Å, Raumgruppe Fdd2 und Z = 8. Die Struktur wurde mittels Patterson-Synthese gelöst und bis R = 0,0343 verfeinert.Die Kristalle sind aus einkernigen Komplexen aufgebaut. Kobalt ist durch zwei Schwefel, zwei Sauerstoff und ein Stickstoff in einer verzerrten trigonal bipyramidaler Struktur fünffach koordiniert. Die wichtigsten Abstände und Winkel sind: Co—S, 2,2680(7); Co—N, 2,065(4); Co—O1, 2,283(2); S—Si, 2,0666(8) Å; S—Co—S′, 119,14(4); N—Co—S, 120,43(2); O1—Co—O1′, 178,81(10)°.
    Notes: The title compound [(t-C4H9O)3SiS]2Co(NCCH3)]1 was obtained by reaction of anhydrous cobalt(II) chloride with tri-tert-butoxysilanethiol and triethylamine in acetonitrile as a solvent. The compound crystallizes as deep-blue orthorhombic plates with a = 17.779(4), b = 45.363(9), c = 9.096(2) Å, space group Fdd2 and Z = 8. The structure was solved by Patterson synthesis and refined to the R value of 0.0343.The crystal consists of mononuclear complexes in which the cobalt atom is five-fold coordinated to two sulphurs, two oxygens and one nitrogen in a distorted trigonal bipyramidal arrangement. The relevant bond distances and angles are: Co—S, 2.2680(7); Co—N, 2.065(4); Co—O1, 2.283(2); S—Si, 2.0666(8) Å; S—Co—S′, 119.14(4); N—Co—S, 120.43(2); O1—Co—O1′, 178.81(10)°.

Reactions of Triphenylsilanethiol with Carbonic Acids, Cyanates, Thiocyanates, and AminesThe reaction of triphenylsilanethiol with carbonic acids yields triphenylacyloxysilane. The reactions with cyanates or thiocyanates of metals yield triphenylsilylcyanate or thiocyanate. The reactions with ammonia or amines yield salts: Ph3SiSH4-nNRn (n = 0, 1, 2, 3). Some Ph3SiSR-derivatives were obtained in reaction of Ph3SiSNH4, with alkylbromides or iodides.

    Description / Table of Contents: Structure of PentaphenyldisilaneFor the first time Pentaphenyldisilane was prepared by Gilman and Goodman. It is produced by the reaction of Ph3SiLi with Ph2ClSiH. The crystal structure presents an ideally staggered conformation. The distance d(Si—Si) = 235.7 pm corresponds to a normal single bond length. This emphasizes the complete relief of the central Si—Si bond by the insertion of only one hydrogen atom.
    Notes: Pentaphenyldisilan entsteht nach Gilman und Goodman bei der Reaktion von Ph3SiLi mit Ph2ClSiH. Die Kristallstrukturanalyse ergab nahezu ideale gestaffelte Konformation. Der Abstand d(Si—Si) = 235,7 pm entspricht einer normalen Einfachbindung, und er zeigt, daß bereits die Einführung eines H-Atoms die zentrale Si—Si-Bindung vollständig entlastet.
