abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
collected data in animal breeding center of iran from 1983 to 2003 was used to estimate the genetic parameters of milk yield in iranian holstein cattle. genetic parameters were estimated, using single and three trait animal models. records of three lactations were divided into thre esub groups according to average milk yield, climitical regions and herd sizes. all variance components in the thr...
this study aimed to investigate the effects of listening strategy training on iranian efl learners listening comprehension and use of such strategies. this work, employing an experimental methodology, was conducted among 60 adult efl learners from a language institute in isfahan, iran, as participants. the participants, who were selected based on the results of a placement test, were assigned t...
Heritability, environmentaland genetic correlations between body weight at hatch (BW0), eight (BW8) and twelve (BW12) weeksof age, body weight at sexual maturity (BWM), age at sexual maturity (AFE),the weight of the first egg laid by the hen (EWM), the mean egg weight from 28 to 32 wks (EW28-32) and egg numbers (ENs) were estimated by the restricted maximum likelihood method under an animal mod...
The aim of this study was to estimate genetic components and parameters of retained placenta and dystocia traits in FOKA dairy farm. The non-genetic factors affecting these traits were evaluated using logistic regression implemented in GENMOD procedure of SAS 9.1 software. In order to do genetic evaluations, 5 Bayesian threshold models of repeat records and a Bayesian bivariate model were used....
Genetic parameters for nuclear and cytoplasmic genetic effects were estimated from preweaning growth data collected on three synthetic lines of beef cattle differing in mature size. Lines of small-, medium-, and large-framed calves were represented in each of two research herds (Rhodes and McNay). Variance components were estimated separately by herd and size line for birth weight and 205-d wei...
The purpose of this study was to compare estimates of genetic parameters for sequential growth of beef cattle using two models and two data sets. Growth curves of Nellore cattle were analyzed using body weights measured at ages 1 (birth weight) to 733 d. Two data samples were created, one with 71,867 records sampled from all herds (MISS), and the other with 74,601 records sampled from herds wit...
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
9 The objectives of this study were to estimate variance components, genetic 10 parameters, EBV, accuracies, and rankings for nine ultrasound and carcass traits in a 11 multibreed Angus-Brahman population using three genomic-polygenic models and one 12 polygenic model (PM). The genomic-polygenic models used the complete GeneSeek 13 GPF250k SNP set (GPM), top 5% SNP (GPMR1), and 5% SNP evenly sp...
