phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...

An understanding of physiological mechanisms of salt tolerance is necessary for breeding programs, in order to select the desired trait in different wheat genotypes. Three bread wheat genotype differing in salt tolerance were employed to assess ion distribution and growth responses under saline conditions. To evaluate ion distribution in plant, sodium and potassium concentrations as well as K+/...

current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...

Damask rose is one of the oldest and most valuable rose varieties that to some extent, tolerates water deficiency. However, the selection and identification of genotypes that are more tolerant to drought stress will be effective in development of cultivation of the plant. In this case, an experiment was performed under in vitro conditions using polyethylene glycol at five levels (0, 25, 50, 75 ...
