This paper addresses the development of performance-based assessment items for ICT skills, skills in dealing with information and communication technologies, a construct which is rather broadly and only operationally defined. Item development followe

Abstract. The goal of this study was to investigate sources of evidence of convergent validity supporting the construct interpretation of scores on a simulation-based information and communication technology (ICT) skills test. The construct definitio

Seit einem halben Jahrhundert ist bekannt, dass in Pflanzen zwei Gruppen von Hormonen – die Auxine und die Cytokinine – die Zellteilung kontrollieren. Aber erst in jungster Zeit beginnt das Bild dieser Kontrolle auf der biochemischen Ebene Kontur

Lovastatin, a potent inhibitor of the mevalonate pathway, has been used in plant cell cycle studies to eliminate the cytosolic cytokinin biosynthesis. However, several implications can blur the results, as cytokinins may be alternatively formed from

The development of castor bean (Ricinus communis L. var. sanguineus) leaves from bud break to abscission was studied to determine whether senescence of phloem precedes or follows chlorophyll degradation in the course of natural ageing of leaves. The

Different environmental stresses to a plant may result in similar responses at the cellular and molecular level. This is due to the fact that the impacts of the stressors trigger similar strains and downstream signal transduction chains. A good examp

Plant meristems are utilization sinks, in which cell division activity governs sink strength. However, the molecular mechanisms by which cell division activity and sink strength are adjusted to a plant's developmental program in its environmental set

The significance of cytokinins for the progression of the cell cycle is well known. Cytokinins contribute to the control of the expression of D-cyclins and other cell cycle genes, but knowledge as to how they affect the progression of the cell cycle
