Background: Since Positive Parenting Program (Triple-P) is one of the ways to improve parent-child interaction, it seems that conducting a meta-analysis will help determine the actual effect size of Triple-P. The aim of this study was to meta-analyze the effect of level 4 Triple-P on interaction of parent-child with special needs in Iran. Methods: The current study is a meta-analysis. Before t...
Genotype-environment interaction for plant breeders has been important as it is a complex issue in breeding for high yield varieties and releasing new genotypes. In order to assess adaptability and stability of sunflower varieties in different climate conditions, twelve cultivars were investigated in Karaj, Shiraz, Birjand, Kashmar and Arak in randomized complete block designs with three replic...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
abstract: advertisements are the most accessible type of authentic materials, and this is one reason why they are used more and more in english teaching classes. for this cause, studies in the field of advertisements are very widespread nowadays. for pun is one aspect which makes advertisements more interesting, it is used more than before in advertisements. use of puns makes an advertisement m...
Submitted for the MAR06 Meeting of The American Physical Society Stability of the quantum spin Hall effect with disorder and interactions CENKE XU, JOEL MOORE, University of California Berkeley — The stability to interactions and disorder of the quantum spin Hall effect (QSHE) proposed for time-reversal-invariant 2D systems is discussed. The QSHE requires an energy gap in the bulk and gapless e...
We present a Chern-Simons theory of the fractional quantum Hall effect in which flux attachment is followed by a transformation that effectively attaches the correlation holes. We extract the correlated wave functions, compute the drift and cyclotron currents (due to inhomogeneous density), exhibit the Read operator and operators that create quasiparticles and quasiholes. We show how the bare k...
We provide numerical evidence that the ground state of a short range interaction model at ν = 1/2 is incompressible and spin-singlet for a wide range of repulsive interactions. Furthermore it is accurately described by a trial wave function studied earlier. For the Coulomb interaction we find that this wave function provides a good description of the lowest lying spin-singlet state, and propose...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
abstract in order to study of two hormones effects of gibberellin and benzyl adenine on (zantedeschia aethiopica cv.childsiana) pot plant characteristics, non dormant rhizomes dipped preplanting in gibberellin solution with concentrations including (0, 100, 200 and 500 ppm) and sprayed in two weeks once to flowering time with benzyl adenine solutions including (0, 100, 200 and 500 ppm). interac...
The spin-Hall effect in the two-dimensional electron gas (2DEG) generates symmetric out-of-plane spin Sz accumulation about the current axis, in the absence of external magnetic field. Here we employ the real space Landauer-Keldysh formalism(1) by considering a four-terminal setup to investigate the circumstances in which this symmetry is broken. For absence of Dresselhaus interaction, starting...
