although decisions or inferences we make based on test scores depend both on characteristics of test-takers and of testing sit- uations, there is just little research which has been undertaken on the effects of these characteristics on test performance (e.g., in’nami, 2006). the effect of listening strategies on listening performance is also unde- niable (vandergrift, 1997). thus, considering t...

in this paper, the problem of lot sizing, scheduling and delivery of several items in a two-stage supply chain over a finite planning horizon is studied. single supplier via a flexible flow line production system (ffl) produces several items and delivers them directly to an assembly facility. based on basic period (bp) strategy, a new mixed zero-one nonlinear programming model has been develope...

   In cross docking strategy, arrived products are immediately classified, sorted and organized with respect to their destination. Among all the problems related to this strategy, the vehicle routing problem (VRP) is very important and of special attention in modern technology. This paper addresses the particular type of VRP, called VRPCDTW, considering a time limitation for each customer/retai...

Proper arrangement of facility layout is a key issue in management that influences efficiency and the profitability of the manufacturing systems. Parallel Row Ordering Problem (PROP) is a special case of facility layout problem and consists of looking for the best location of n facilities while similar facilities (facilities which has some characteristics in common) should be arranged in a row ...

background: as the unintended pregnancy has certain maternal and neonatal consequences and knowing accurate prevalence can lead to useful planning for its diminishing; this study was carried out to determine the prevalence of unintended pregnancy in iran. methods: a systematic review and meta analysis study was applied. 33 articles were meta-analyzed and reviewed by two different groups. employ...

objective(s)staphylococcus aureus is a prevalent pathogen worldwide. methicillin resistant s. aureus (mrsa), which is usually multi-resistant in hospitals, has been a daunting challenge for clinicians for more than half a century. the aim of this systematic review and meta-analysis is to determine the relative frequency (rf) of mrsa in different regions of iran.materials and methodssearch terms...

background: as a dna repair protein, flap endonuclease 1 is a key enzyme in maintaining genomic instability and preventing carcinogenesis. two single nucleotide polymorphisms (snps), -69g>a and 4150g>t are associated with dna damage. this meta-analysis is to evaluate the genetic effects of fen1 gene snps (-69g/a and 4150g/t) and the susceptibility to diseases, including glioma risk, breast canc...

conclusions although differences between the two products were very close to each other, they reported similar effects on joint bleeds. further clinical studies should be performed by incorporating a standardized measurement in comparative efficacy of apcc and rfviia. results the mean of bleeding reduction in apcc and rfviia were 71.2% with ci 95% (lower limit 86.8% and upper limit 82%) and 72....

Abstract. The meta-plot is a descriptive visual tool for meta-analysis that provides information on the primary studies in and results of meta-analysis. More precisely, portrays (1) precision statistical power meta-analysis, (2) estimate confidence interval random-effects (3) cumulative yielding robustness check meta-analytic effect size with respect to studies’ precision, (4) evidence publicat...
