regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
In this study, displacement field around v-notches of a poly methyl metha crylate (PMMA) specimen with tip cracks will be analyzed using digital image correlation technique. First intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...
background and objectives: life satisfaction is one of the most important indicators for evaluation of mental health status in general population including university students. in this field, the appropriate tool is necessary. so, this study was carried out in order to assess the reliability and validity of the swls in the students of kashan nursing & midwifery faculty (knmf), kashan, iran, in ...
In order to analyze the pattern in the geographical distribution of cancer death in 24 countries of the world, correlation coefficients were calculated between pairs of mortality rates of different cancer sites, using the data for 13 sites in males and 14 sites in females over 18 years from 1950 to 1967. Then factor analysis by means of varimax method was performed on 13 x 13 correlation matrix...
The basic idea of factor analysis is the following. For a given set of manifest variables x1, . . . , xp one wants to find a set of latent variables ξ1, . . . , ξk, fewer in number than the manifest variables, that contain essentially the same information. The latent variables are supposed to account for the dependencies among the manifest variables in the sense that if the latent variables are...
The purpose of this paper is to determine reliability (internal consistency) and validity of satisfaction with life scale in two samples of Iranian students. The first sample was composed of 866 persons (490 females and 376 males) with average age of 22.60 while the second one was composed of 300 persons (131 females and 169 males) with average age of 20.87. All the subjects were asked to answe...
polyurethane/zeolite 13x nanocomposite films were fabricated using solution casting method. the synthesized nanocomposite films were structurally characterized using sem, tga and tensile analysis. sem images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...
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...
