TUDGE, JONATHAN R. H. Processes and Consequences of Peer Collaboration: A Vygotskian Analysis. CHILD DEVELOPMENT, 1992, 63, 1364-1379. A sample of 162 children aged from 5 to 9 was pretested to discover each child's "rule" for predicting the movement of a mathematical balance beam. Children then worked alone, with a partner who used the same rule, with a partner who was more competent, or with ...

Wireless Multimedia Sensor Networks should transfer a large quantity of multimedia data in a timely manner within a limited time; thus, it is very important to provide a low degree of delay and the maximum throughput. This paper proposes an efficient traffic control mechanism of multimedia data requiring real-time transmission in wireless multimedia sensor network with the path determination ba...

Current-sheet evolution near a hyperbolic magnetic neutral line in Hall magnetohydrodynamics (MHD) is investigated. An exact analytical solution describing a self-similar evolution is given. This solution shows a hastening of the current-sheet formation process at intermediate times by the Hall effect but subsequently a quenching by the Hall effect of the finite-time singularity exhibited in id...

To the Editor: Dr. L. S. Gettes has alerted me of the fact that three figures appearing in our review article devoted to the subject of ventricular tachycardia (Circulation 47: 1364, 1973) appear to be adaptations of figures which he had published earlier (Am J Cardiol 28: 526, 1971). These figures (in our article Nos. 1, 7 and 8) were diagramatic simplifications of certain electrophysiologic c...

Even though most researchers would agree that in symbiotic relationships, like the one between parent and child, influences become reciprocal over time, empirical evidence supporting this claim is limited. The aim of the current study was to develop and test a model describing the reciprocal influence between characteristics of the parent-child relationship, such as closeness and conflict, and ...

PhytoPath (www.phytopathdb.org) is a resource for genomic and phenotypic data from plant pathogen species, that integrates phenotypic data for genes from PHI-base, an expertly curated catalog of genes with experimentally verified pathogenicity, with the Ensembl tools for data visualization and analysis. The resource is focused on fungi, protists (oomycetes) and bacterial plant pathogens that ha...

A 40-year-old obese black woman developed abdominal pain with progressive generalized weakness over several days. Physical examination was normal except for several small bruises on her extremities. Laboratory data revealed the following: hemoglobin, 5.0 g/dL; platelet count, 4000/mL; creatinine, 0.8 mg/dL; lactate dehydrogenase, 1364 U/L. Peripheral blood smear revealed many schistocytes. Acqu...

It has been assumed that endogenous synthesis by the platelet precursor cell, the bone marrow megakaryocyte, is the major source of platelet a-granule protein. To test this hypothesis, we used mRNA phenotyping to detect in megakaryocytes the presence of mRNA transcripts specific for various proteins. Our results indicate that megakaryocytes synthesize platelet factor 4, a protein relatively spe...
