In the original study, “The Effect of Exercise on the Work-Family Interface: A Field Experiment Using Group Exercise Classes”, a significant decrease in both WIF (work interference with family) and FIW (family interference with work) was seen in a long-term exercise group. This follow-up survey was done to ascertain whether study participants are still exercising after 11 months and if both WIF...

Radioligand positron emission tomography (PET) with dual scan paradigms can provide valuable insight into changes in synaptic neurotransmitter concentration due to experimental manipulation. The residual t-test has been utilized to improve the sensitivity of the t-test in PET studies. However, no further development of statistical tests using residuals has been proposed so far to be applied in ...

INTRODUCTION Research on medical students shows that adopting self-regulation of effort, time, and study strategies can positively influence academic achievement. The purpose of the current study was to assess learning and study strategies in medical students. METHODS This cross-sectional study was carried out in 2014-2015 at Isfahan University of Medical Sciences. The sample size was determi...

In this paper, we solve the sequential stopping problem for a class of simulation problems in which variance estimation is difficult. We establish the asymptotic validity of sequential stopping procedures for estimators constructed using the sectioning (replication) methods with a fixed number of sections. The limiting distribution of the estimators at stopping times as the error size (the abso...

1226 M any studies have too small a sample size for their fi ndings to be conclusive, but large studies are expensive and time-consuming. Meta-analysis is an alternative to conducting large studies in tackling the problem of small sample size, by combining available small studies to increase the total sample size. Since the 1980s, meta-analysis has been widely used in summarizing results from c...

Null hypothesis significance testing (NHST) is the most commonly used statistical methodology in psychology. The probability of achieving a value as extreme or more extreme than the statistic obtained from the data is evaluated, and if it is low enough, the null hypothesis is rejected. However, because common experimental practice often clashes with the assumptions underlying NHST, these calcul...

Melatonin's neuroprotective action has been demonstrated in experimental models of brain ischaemia. The relationship between stroke and melatonin levels has been based on scarce and small sample size studies. In addition, the changes have not been correlated with the age of patients. We compared levels of nocturnal urinary melatonin and its metabolite, 6-sulfatoxymelatonin (aMT6S) in a large se...
