Quercus cerris extracts obtained by distinct separation methods and solvents: Total and friedelin extraction yields, and chemical similarity analysis by multidimensional scaling

A recently proposed multidimensional similarity analysis methodology was used to analyze the dimensionality of a set of selected classroom social reinforcers. Judges were elementary school teachers who frequently administered such reinforcers. The three extracted evaluation dimensions, accounting for 81% of the judgmental variance, were all readily interpretable. The success of this exploratory application of a multidimensional scaling procedure in the realm of educational concerns suggested further uses for such investigative methodologies with regard to other forms of educational judgment-evaluation.

Previous studies have inferred that the side effects of physical disturbance associated with bait-collecting for the sandprawn Callianassa kraussi are more deleterious than the actual removal of the prawns. The present study was specifically designed to disentangle the side-effects of trampling and disturbance associated with using suction pumps for bait-collecting. Separate areas were sucked over with a prawn pump at three different intensities, and the prawns collected from these areas subsequently returned to them. A parallel treatment involved trampling the sediment at levels comparable to the 'sucking' intensities, without removing the prawns. The responses of the meiofauna, macrofauna and microflora were assessed six weeks after this disturbance.Prawn densities were depressed six weeks following both sucking and trampling but recovered by 32 weeks. The meiofauna responded positively to some of the disturbance treatments; macrofaunal numbers on the other hand, declined in most treatment areas, and similarity analysis and multidimensional scaling showed that macrofaunal community composition in the most-disturbed areas was distinct from that in other areas. Chlorophyll levels were reduced at the more intensely-disturbed sites.The results corroborate the conclusion that trampling per se has almost the same effect as sucking for prawns, on both the prawns and on the associated biota. This has important implications in terms of managing the use of lagoonal and estuarine ecosystems.

Scaling Procedure

A recently proposed multidimensional similarity analysis methodology was used to analyze the dimensionality of a set of selected behavior problems sometimes exhibited by elementary students in classroom situations. Judges were elementary school teachers who frequently encountered such behavior problems. The three extracted evaluation dimensions, accounting for 82% of the judgmental variance, were all readily interpretable. The success of this exploratory application of a multidimensional scaling procedure to educational concerns suggested further uses for such investigative methodologies with regard to other forms of educational judgment-evaluation.

Similarity Analysis

The dimensions used in the judgment of the informativeness of picture sections were investigated by means of a recently proposed methodology, multidimensional similarity analysis. 10 judges (college students) rated the informational similarity of 32 areas within a single picture. The five extracted dimensions accounted for 86% of the judgmental variance and were all readily interpretable. These dimensions were discussed with respect to an earlier study in which eye movements of subjects viewing this picture were recorded.

Descriptor Space

The chemical similarity of antibacterial cyclic peptides and peptidomimetics was studied in order to identify new promising cyclic scaffolds. A large descriptor space coupled with cluster analysis was employed to digitize known antibacterial structures and to gauge the potential of new peptidomimetic macrocycles, which were conveniently synthesized by acylbenzotriazole methodology. Some of the synthesized compounds were tested against an array of microorganisms and showed antibacterial activity against Bordetella bronchistepica, Micrococcus luteus, and Salmonella typhimurium.
