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...
The implied variances of 167 firms are examined over the period 1991 through 1995. The traditional market model of returns is shown to be a good first order model for explaining the cross section of variances though firm specific variances appear to exhibit stronger covariance than the market model predicts. The existence of a positive bias over realized and forecast variances is documented. Th...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
The accurate planning and management for sustainable agriculture results in appropriate behaviors ofindividuals towards sustainability through changes happened in individuals’ knowledge and attitudesof sustainability. A survey of natural resources and agricultural researchers (N = 85) was conducted inIranian Province of ILAM to explore their attitudes of sustainable agriculture and to identify ...
We study the blocks of interpoint distances, their distributions, correlations, independence and the homogeneity of their total variances. We discuss the exact and asymptotic distribution of the interpoint distances and their average under three models and provide connections between the correlation of interpoint distances with their vector correlation and test of sphericity. We discuss testing...
Introduction: This study aimed to assess relationship between affective self-regulation and study skills with educational performance of students of Isfahan University of Medical Science. Methods: 313 students who were selected randomly from the available male and female students in terms of 2-8, among the seven faculties answered the provided questionnaires.

The aim of this study was to investigate relationships between soil properties and plant species to determine the most effective factors separating vegetation communities in Rineh rangeland. Three stratifying variables were selected including slop, aspect and elevation. The study area was partitioned by combining these classes to generate homogenous units. 1m2 quadrates were located at sampling...
