The article deals with the motivational mechanisms of learning and cognitive motivation of students. Mechanisms (driving force) of educational and informative motivation described by many researchers, presentation of them formed in the psychological and pedagogical knowledge. An important issue is the time in favor of diagnostic facilities, and proper diagnostic tools.

A partial sequence of the mtDNA ND5 gene region was used for population study in Persian sturgeon (west and east areas of southern Caspian Sea). The result showed that although this approach was informative for phylogenetic study in sturgeon, it was less informative for population study in Persian sturgeon. 

OBJECTIVES To determine the effectiveness of a motivational interviewing-based educational program in reducing the number and intensity of new caries and bacterial dental plaque levels at 6 months post randomization. STUDY DESIGN A randomized and single blind clinical trial in 100 schoolchildren between 6-10 years of age presenting the highest risk score of caries according to the Caries Mana...

This paper surveys the empirical evidence on causal effects of educatio studies in the light of their underlying identifying assumptions. We work o which lead to rather different interpretations of the estimated causal effect extend causal return estimates are informative regarding educational policy Despite the substantial methodological differences, we have to conclude t and do not deviate su...

We study social comparisons and status seeking in an interconnected society. Individuals take costly actions that have direct benefits and also confer social status. A new measure of interconnectedness—cohesion—captures the intensity of incentives for seeking status. Equilibria stratify players into social classes, with each class’s action pinned down by cohesion. A network decomposition algori...

This paper develops an informative column generation and decomposition method for a capacitated multi-item lot sizing and facility location problem with backlogging. The method hybridizes column generation to achieve a relaxed linear solution and a decomposition method (i.e., relax-and-fix) to achieve a feasible solution. The two solutions are used for a neighborhood search procedure that fixes...
