Mathematics achievement differences among 632 fifth graders were analysed in a longitudinal design and explained in a structural equation framework provided by LISREL, separately for four types of classrooms. The results replicated the findings of an earlier study (Schneider \& Treiber, 1984) in that the local nature of achievement models could be demonstrated. That is, the structural components of the causal models could not be generalized across the four groups of classrooms. The inclusion of a second grouping criterion (i. e., achievement gainJ proved useful in that a better model fit was always obtained for classrooms with high achievement gains. As a global model test ignoring group and classroom membership did mask the differential validity of the achievement model in the various subgro.ups, the need for multilevel approaches was emphasized.}, subject = {Schulleistung}, language = {en} } @incollection{SchneiderHelmke1986, author = {Schneider, Wolfgang and Helmke, Andreas}, title = {Mehrebenenanalytische Ans{\"a}tze zur Erkl{\"a}rung von Schulleistungen}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-87348}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1986}, abstract = {No abstract available.}, subject = {Schulleistung}, language = {de} } @misc{Schneider1986, author = {Schneider, Wolfgang}, title = {How to avoid traps and fallacies: The multilevel issue in educational research}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-87336}, year = {1986}, abstract = {Review of "Hans Oosthoek and Pieter van den Eeden (Eds.)

The receptors showed homogeneaus affinities for antagonists but two affinity states for the agonist (-)-epinephrine, which were modulated by guanine nucleotides. Van't Hoffplots of antagonist binding had a break point at about 18° and considerable diversity between 18° and 0°. Agonist binding to both affinity states showed a similar break point; agonist binding to the high affinity state was characterized by a large entropy component compared to the low affinity state. This entropy component was reduced at higher concentrations of sodium, indicating that it may be due to Iiberation of sodium ions. Measurements of the fluorescence of 1-anilin-8-naphthalenesulfonate showed thermotropic phase transitions of theplatelet membranes at about 17°. The transition temperature was decreased to about 12° by addition of 1 0 mM octanoic acid. Octanoic acidalso shifted the break points of the van't Hoffplot of antagonist and low affinity agonist binding from 18° to 12°. High affinity agonist binding, however, remained unchanged. It is concluded that agonist-specific thennodynamic characteristics of ligand binding to a2-receptors of human platelets can only be investigated by regarding differences between high and low affinity agonist binding. These differences include an entropy increase upon Iigand binding, which is in part due to enhanced liberation of sodium ions, and a loss of sensitivity to fluidity changes in the outer layer of the plasma membrane.}, subject = {Molekularpharmakologie}, language = {en} }
