In this paper, using a relation between Schur multipliers of pairs and triples of groups, the fundamental group and homology groups of a homotopy pushout of Eilenberg-MacLane spaces, we present among other things some behaviors of Schur multipliers of pairs and triples with respect to free, amalgamated free, and direct products and also direct limits of groups with topological approach.

based on current expectations, when the free float is more, more deals done and consequently the share price volatility will also increase. shareholders expect more profits from stocks which have more free floats. this paper examines the kind of relationship between free float and liquidity, risks and returns and the degree of influence of these variables in the percentage of free float. we con...

Snowflake growth is an example of crystallization, a basic phase transition in physics. Studying snowflake growth helps gain fundamental understanding of this basic process and may help produce better crystalline materials and benefit several major industries. The basic theoretical physical mechanisms governing the growth of snowflake are not well understood: whilst current computer modeling me...

human free acts have always been one of most difficult but important issues in philosophical debates. in this paper, i will try to provide an interpretation of these acts and argue for human free will and freedom. to this end, i will first, disucss the distinction of necessary acts from free acts, and then will argue for the free will, and its relation to free acts and freedom. finally, some co...

The present study considered whether maternal knowledge mediated the relation between overt marital conflict and preadolescent behavioral competence. Four years of self-report data were collected from 133 mothers and their preadolescents, beginning when the preadolescents were in 4th grade. Marital conflict, maternal knowledge, and preadolescent behavioral competence were assessed at all 4 time...

Behavioral finance and classical finance based on utility maximization appear to be mutually exclusive schools of thought. Despite the fundamental difference, we show that behavioral finance also has a linear relation between risk and return. This relation is obtained without the assumptions of market equilibrium, rational expectations, a specific utility function and the market portfolio. In t...

Currently, many studies show the effectiveness of elimination (gluten-free and case-free) diets in correcting not only the symptoms of gastrointestinal disorders in patients with autism but also in correcting behavioral indicators. The results of the inclusion of gluten and case free diets were analyzed in the complex of therapeutic measures in a child with autism spectrum disorders. The ...
