Count what counts: improving charitable investor access to the community development sector with better data and better analytical models

Developing investor-quality analysis could trigger a tremendous increase in donations to community development nonprofits from philanthropic sources. Bamberger and Gross survey existing analysis tools and make suggestions for a better one.

One pot domino synthesis of polyvicinalamine monomers

On a genere de l'imidazole par une reaction de type domino in situ entre le glyoxal, le formaldehyde et deux unites d'ammoniac aqueux. L'addition de bicarbonate aqueux et d'un anhydride carboxylique ou d'un dicarbonate de dialkyle conduit a la formation de la N,N'-diacyl- ou N,N'-dicarbalkoxy-2-hydroxyimidazoline correspondante. Il s'ensuit une reaction de clivage de cycle de Bamberger qui permet d'isoler facilement le cis-1,2-di(acetamido)ethene, le cis-1,2-di(propylamido)ethene, le cis-1,2-di(ethoxyamido)ethene, le cis-1,2-di(tert-butoxyamido)ethene ou le cis-1,2-di(benzamido)ethene sous la forme de solides. La facilite et la generalite offerte par cette approche monotope implique une voie efficace du point de vue des couts en vue de la synthese de routine de precurseurs d'amines oligo- et polyvicinales

Music to measure: symbolic representation in children's composition.

Eisner maintains that the arts education community needs "empirically grounded examples of artistic thinking related to the nature of the tasks students engage in, the material with which they work, the context's norms and the cues the teachers provide to advance their students' thinking" (2000, p. 217). This paper reflects on the results of collaborative action research between teachers and university researchers in New Zealand who have been investigating how children develop and refine their ideas and related skills in music. The paper focuses specifically on the results of action research in which the impact of symbolic representation on idea development and refinement in music is examined. It raises some issues and points of tension for generalist and specialist teachers when fostering creative idea development in music
